The base plate 1, the supporting feet 11 and the base plate 2 are all made of closed-cell foam materials, the closed-cell foam materials are preferably made of EPS foam materials, namely polystyrene foam materials, the closed-cell foam materials are foam plastics with hard closed-cell structures and have the characteristics of low density, high structural strength and abrasion resistance, so that the load of the forklift can be reduced, and the damage of goods caused by transportation vibration can be relieved. Meanwhile, the polystyrene foam material is low in deformation degree, so that the goods on the polystyrene foam material are not prone to being skewed and overturned, and the stability of goods transportation is improved. The base plate 1 and the base plate 2 may simultaneously bear vertical pressure and horizontal shearing force, especially the base plate 1 and the base plate 2 between the adjacent base plates 11 are more easily broken, and based on this, the density of the EPS foam material of the base plate 1 and the base plate 2 of the present embodiment is higher than that of the base plate 11. The base plate 1 and the supporting leg 11 can be fixed by gluing or by bolts.

Referring to fig. 1 and 2, the support legs 11 are 9 and uniformly distributed at the bottom of the rectangular substrate 1, and are specifically arranged in a shape like a Chinese character tian, that is, 8 support legs 11 are distributed around the edge of the substrate 1 at intervals, one is at each of four corners, one is at the center of each of the four edges, and the remaining 1 support legs are distributed in the central area of the substrate 1. As shown in fig. 3, the touchdown area and the horizontal cross-sectional area of each of the 4 supporting legs 11 located at the corners of the substrate 1 are not larger than those of the 5 supporting legs 11 in the other regions, so as to reinforce the central region with concentrated stress and the supporting legs 11 close to the central region, and locally improve the supporting strength thereof, so that the part of the supporting legs 11 bears larger static load and dynamic load, thereby reducing the material consumption of the 4 supporting legs 11 at the corners of the substrate 1 and realizing the optimal allocation of resources; on the other hand, the deformation degree of the supporting legs 11 in the central area and the area close to the center is reduced, the height difference between the substrate 1 and other areas caused by the excessive collapse of the supporting legs 11 in the central area is avoided, and the phenomenon that the substrate 1 is bent or even broken due to the height difference is avoided.

The section of the supporting foot 11 parallel to the bottom surface of the base plate 1 is rectangular, and the section area of the supporting foot 11 parallel to the bottom surface of the base plate 1 is gradually reduced along the direction far away from the base plate 1, so that the supporting foot 11 can be conveniently demoulded during the production and processing of the packaging structure. And the lateral wall of two adjacent kickers 11 forms slot 12, and the width of slot 12 is greater than fork truck's fork, and slot 12 has many, and it wholly is "well" font in base plate 1 bottom and arranges to this makes things convenient for fork truck to insert slot 12 from arbitrary orientation in four directions, thereby drives packaging structure and transports the goods.

The foot 11 is susceptible to wear due to the fork contacting the foot 11 when inserted into the slot 12. Therefore, the arm brace 11 is sleeved with a protective sleeve (not shown in the figure), the protective sleeve is square and can be made of engineering plastics, metals, alloys and the like, the edge of the top opening of the protective sleeve is abutted against the bottom surface of the substrate 1, and the inner wall of the protective sleeve is fixedly bonded with the arm brace 11 through glue.

Referring to fig. 1 and 2, the tie plate 2 is rectangular, the plurality of placing grooves 21 are provided, and each placing groove 21 may have a uniform shape and size for fitting the same kind of goods. And the placing grooves 21 are preferably even, and a plurality of placing grooves 21 are symmetrically distributed along the connecting line of the middle points of the edges of the two sides which are not adjacent on the base plate 2, so that after goods are placed on the base plate 2, the whole gravity center of the packaging structure is positioned at the center of the base plate 2, thereby reducing the inclination of the goods and facilitating the normal transportation of the goods. In another embodiment, each placing groove 21 can be different in shape and size to adapt to different kinds of goods, and meanwhile, the gravity center position of the whole goods and the packaging structure after the goods are placed needs to be tested, and the position of the placing groove 21 is redesigned and adjusted according to the test result.

Be provided with on the 21 inner wall of standing groove and prevent being stained with the layer, antiseized layer can adopt plastic coating or plastic film, and plastic coating can adopt the mode of spraying to arrange, and the plastic film then directly cover in the standing groove can, plastic coating can adopt the teflon coating for products such as dress compressor prevent compressor surface adnexed paint and foam adhesion, be used for conveniently clearing up impurity such as dust, paint piece, machine oil that the product left, thereby conveniently load and unload the product.

The cushion plate 2 is located between the placing grooves 21 and is provided with the hollow grooves 22, the hollow grooves 22 are used for enabling the wall thicknesses of the placing grooves 21 to be equal, the shapes of the hollow grooves 22 need to be determined according to the wall thicknesses of the placing grooves 21, the groove walls of the placing grooves 21 are used for supporting goods, meanwhile, the vibration of the goods is reduced through self small deformation, and the hollow grooves 22 are used for providing deformation spaces for the groove walls of the placing grooves 21. And the wall thickness of the placing groove 21 needs to be tested according to the quality, hardness and the like of the placed goods, so that the situation that the wall thickness of the placing groove 21 is too large and cannot play a role in vibration reduction is avoided, the situation that the wall thickness of the placing groove 21 is too small and the wall thickness of the placing groove 21 is torn is avoided, for example, for goods such as compressor products with large mass, the wall thickness of the placing groove 21 needs to be maintained above 2.5 centimeters, and therefore the wall thickness of the placing groove 21 is kept at the deformation amplitude and the structural strength of a better layer. For the goods of the plastic products, the wall thickness of the groove wall of the placing groove 21 can be reduced to 1-2 centimeters, so that the area of the groove wall of the placing groove 21 on the surface of the base plate is reduced, more placing grooves for placing the goods are conveniently designed on the base plate, the quantity of the goods which can be transported in a single time is increased, and the transportation efficiency is improved.

The embodiment also discloses a processing technology, and with reference to fig. 4, the specific steps are as follows:

s100: and acquiring the shape parameters of the loaded goods.

Specifically, the shape parameter obtaining mode may adopt manual measurement, or directly obtain data such as a factory product report of the goods, or adopt a three-dimensional scanner to perform data acquisition, and finally obtain shape parameters such as length, width, surface curvature, surface characteristics, and the like.

S110, judging whether the loaded goods have historical use records;

if not, go to step S200 a;

if yes, go to step S200 b.

Specifically, the executive body may be a worker, the worker distinguishes whether the goods is designed with a corresponding mold by searching for information, or an intelligent terminal such as a processor inquires whether the goods name, model or number of the entered goods contains information of the goods, if no history record exists, the executive body is determined as a new goods and needs to be entered; if the catalyst exists, the catalyst can be directly used, and intermediate processes are reduced.

S200 a: and calculating the processing parameters of the upper die according to the shape parameters, and storing the processing parameters in the model library.

Specifically, go up the mould and correspond 2 tops of backing plate, the concave part in the convex part corresponds standing groove 21 on the goods, and the concave part on the goods corresponds the convex part of standing groove 21 inner wall, and shape and size is unanimous, to some fold parts or the subregion concave part on the goods, can ignore to this reduces the drawing of patterns degree of difficulty, saves raw and other materials simultaneously.

S200 b: and directly reading the processing parameters of the upper die corresponding to the goods, which are prestored in the model library.

Specifically, if the current goods have historical use records, the processing parameters corresponding to the goods and prestored in the model base can be read, so that the upper die can be processed by directly using the processing parameters, the calculation procedures are reduced, and the workload is reduced; and whether the forming grinding tool corresponding to the goods is stored or not can be inquired, and if the corresponding forming grinding tool is found to be stored in the warehouse, the forming grinding tool corresponding to the goods can be directly called for use, so that the energy and resource loss caused by repeated processing is reduced.

And S300, acquiring preset processing parameters of the lower die.

Specifically, the lower mold corresponds to the bottom of the substrate 1 and corresponds to the supporting legs 11, and therefore grooves corresponding to the number of the supporting legs 11 need to be formed in the lower mold. Because the bottom of the base plate 1 obtained by lower die machining and the part of the supporting feet 11 only need to be matched with the pallet fork of a standard forklift, frequent replacement is not needed, and therefore, the upper die only needs to be replaced to change the placing position and the shape of the placing groove 21 for different goods, so that the die design and the packaging structure machining process are simplified, the cost is reduced, and the packaging structure production efficiency is improved. In another embodiment, for different qualities of goods, the supporting legs 11 and the base plate 1 with different shapes and sizes are selected, generally, the larger the quality of the goods is, the thicker the supporting legs 11 need to be, and the lower die needs to be correspondingly customized and adjusted, so that the supporting legs are adapted to various types of goods, and the application range is expanded.

And S400, processing according to the processing parameters of the upper die and the lower die to obtain the forming die.

Specifically, after the upper die and the lower die are specified, the overall thickness of the base plate 1 and the base plate 2 after combination needs to be selected and matched, and the overall thickness of the base plate 1 and the base plate 2 is designed according to goods with different weights, goods with different sizes, the placement density of the goods on the base plate 2 and the like. When goods weight is great, need carry out the thickening design to base plate 1, backing plate 2 whole, avoid packaging structure to receive the too big phenomenon of breaking down that takes place of load. When the goods size is comparatively special, for example the aspect ratio is big and when leading to standing groove 21 to deepen, need thicken to the whole package structure to this avoids standing groove 21 tank bottom and base plate 1 bottom too narrow and leads to standing groove 21 to run through or the too thin cracked phenomenon of package structure. The adjustment of the whole thickness of the packaging structure can be realized by setting the sliding stroke of the upper die and/or the lower die.

S500, processing by using a forming die and a preset forming machine according to process data to obtain a packaging structure;

specifically, the preset molding machine adopts an EPS molding machine, and the base plate 1 and the backing plate 2 which are integrally molded from the EPS foam material and meet the expectation are manufactured by the EPS molding machine.

Because the structural strength, toughness, elasticity and the like of the EPS foam material are related to the process data such as the expansion coefficient, the forming density and the like of the EPS foam material, the process data are adjusted according to the designed packaging structure load, and the selection steps of the process parameters are as follows:

s510, acquiring the estimated weight of the loaded goods;

and calculating the load corresponding to the packaging structure according to the estimated weight and the preset area of the base plate.

Specifically, the estimated weight of the loaded goods is generally manually analyzed and evaluated according to the types of the goods and the quantity of the goods to be placed, or a weighing platform is adopted for weighing, and the area of the base plate 2 can be customized according to the size of the goods. The load, specifically the surface load, is calculated by the area of the backing plate 2 and the estimated weight of the goods, the unit is KN/square meter, the static load and the dynamic load can be obtained through testing, or estimated by an estimation simulation algorithm, and details are not repeated here.

S520, obtaining process data of the packing structure filling material according to the load of the packing structure;

and processing according to the process data to obtain the packaging structure.

Specifically, the packing structure filling material is an EPS foam material, the load of the packing structure is a load designed for the cargo to be supported, and the possibility that the packing structure is broken and excessively deformed under the designed load is below a normal level. Through a load test, a load-process parameter reference relation can be obtained, and by referring to the load-process parameter reference relation, a worker can conveniently select corresponding process parameters according to a designed load, adjust the process data such as the proportion of EPS raw materials, process conditions and the like, so as to adjust the final molding density of EPS, and enable the EPS to reach the expected structural strength and other characteristic indexes.

Through tests, the currently more ideal packaging structure size and EPS density standard are as follows:

length or width of the entire substrate 1 and the pad 2: 0.9m-1.2 m;

thickness of the entire substrate 1 and the backing plate 2: 0.08m-0.2 m;

In another embodiment, the toe guard 4 is provided with a limiting hole, the extending direction of the limiting hole is perpendicular to the edge of the toe guard 4, the PP packing belt 42 passes through the limiting hole to pack the product, and the limiting hole replaces a limiting channel to limit the PP packing belt 42 and prevent the PP packing belt 42 from falling off.

The force sensor 43 is arranged on one side, close to the bottom surface of the substrate 1, of the foot protection plate 4, the force sensor 43 is used for detecting acting force between the foot protection plate 4 and the bottom surface of the substrate 1, and the force sensor 43 is connected with an intelligent terminal of a user, such as a mobile phone and a computer, through a wireless radio frequency module, so that mechanical data are sent to the intelligent terminal for the user to check. Force sensor 43 may be a sheet force sensor model HH8204L38 and the wireless radio frequency module may be a SX1278-S model.

The third embodiment of the present application has the following implementation principle: when the force sensor is mounted, the user attaches the toe guard 4 to the edge of the substrate 1, and the side on which the force sensor 43 is placed is attached to the bottom surface of the substrate 1. When the packaging device is used, a user penetrates the PP packaging belt 42 between the limiting pieces 41 of the toe guard 4 and then penetrates the slot 12 to perform a packaging process.

After the binding and packing of the goods are completed, mechanical data are collected to obtain a pressure value, whether the pressure value is between a preset lower limit value and a preset upper limit value or not is judged, and if yes, the fact that the force of the packing belt 42 is moderate is indicated.

If the pressure value is smaller than the preset lower limit value, the fact that the strength of the packing belt 42 is insufficient and too loose is obtained, the goods are prone to toppling and loosening is indicated, and at the moment, the tightness degree of the packing belt 42 needs to be adjusted by a user, so that the stability of goods transportation is improved.

If the pressure value is greater than the preset upper limit value, it indicates that the force of the packing belt 42 is too large and tightened too tightly, and the goods and the packaging structure are easily crushed, and at this time, the tightness degree of the packing belt 42 needs to be adjusted by a user, so that the goods and the packaging structure are protected.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
