The conventional Fused Deposition Modeling (FDM) is a method in which a filamentary material (e.g., a thermoplastic, wax, or metal fuse) is extruded from a heated nozzle and is deposited at a constant rate according to a predetermined trajectory for each layer of the part. And when one layer is finished, the workbench descends one layer thickness to carry out superposition deposition on a new layer, and the steps are repeated to finally realize the deposition molding of the part.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, the use of directional terms such as "upper, lower, left, right" generally means upper, lower, left, right as viewed with reference to the accompanying drawings, unless otherwise specified; "inner and outer" refer to the inner and outer relative to the profile of the components themselves.

The invention provides a printer, which comprises a mesh base plate 1, a first spray head 2 arranged above the mesh base plate 1 and used for spraying fiber objects on the mesh base plate 1 to print plane fabrics of clothes, and a water jet device used for water jet of the plane fabrics on the mesh base plate 1 through meshes on the mesh base plate 1 to entangle the fiber objects.

Wherein, the diameter of the spray hole of the first spray head 2 can be 0.1-0.5mm, and the first spray head 2 needs to be a high temperature resistant spray head and can be provided with an air pump, which is beneficial for the polymer to form a uniform fiber web under certain temperature and pressure. In addition, the first nozzle 2 can be made of stainless steel, nickel-based alloy, hastelloy and other materials; the reticular bottom plate 1 can be made of stainless steel, rare metal and other materials.

In the technical scheme, the fibers sprayed on the mesh-shaped bottom plate 1 do not need to be regularly arranged, compared with a process of spraying the fibers according to a preset track to form regularly arranged filiform materials and stacking the materials layer by layer, the requirement on the precision of equipment is reduced, the operation difficulty is reduced, the printing efficiency of the garment is obviously improved, the cost is reduced to a certain extent, the fibers can be entangled by a spunlace (spunlace is a technology of utilizing high-pressure sprayed fine water flow to enable the fibers to be mutually crossed and entangled into a net), compared with a mode of depending on self bonding of each layer of material, the strength of the garment is higher, and the user requirements can be better met.

As shown in fig. 1-2 and 5-6, the water jet device preferably comprises a water jet pipe 31 and a water pump 32 connected to the water jet pipe 31, wherein the water jet pipe 31 is provided with a plurality of water jet holes H for performing water jet. In order to ensure that the water flow from the water jet holes H of the water jet pipe 31 can smoothly pass through the mesh base plate 1 to perform the water jet punching on the fiber material on the mesh base plate 1, the water jet holes H are arranged on the pipe wall of the water jet pipe 31 facing the mesh base plate 1. Thus, the fiber material printed on the mesh base plate 1 can be hydroentangled by the water flow having a certain pressure from the water pump 32 while passing through the water jetting holes H of the water jetting pipe 31, so that the fiber material is entangled to improve the strength of the flat fabric.

The arrangement of the water jet pipes 31 under the mesh-type base plate 1 for performing the water jet may be selected variously, and preferably, the portion of the water jet pipes 31 corresponding to the mesh-type base plate 1 is a plurality of linear pipes arranged in rows and communicated with each other, such as a matrix arrangement shown in fig. 2, a similar arrangement of a zigzag shape shown in fig. 3 (in which a first end a of the pipe is connected to the water pump 32 and a second end b thereof is closed in order to make the water sprayed from the water jet holes H have a certain pressure), and an arrangement of a plurality of rows of branch pipes N connected to the same main pipe M in fig. 4 (in which a second end of the plurality of rows of branch pipes N is closed in order to make the water sprayed from the water jet holes H have a certain pressure, a first end c of the main pipe M is connected to the water pump 32 and a second end d thereof is closed or connected to a first end of one of the branch pipes N), or the parts of the water spray pipes 31 corresponding to the mesh-shaped base plate 1 are mutually communicated multi-circle coiled pipes, such as an arrangement mode shown in fig. 6 in which a plurality of annular pipes E are sleeved together and connected with the same water inlet pipe F and a spiral arrangement mode shown in fig. 7 (wherein one end of the inside of the spiral pipe can be closed, and the other end of the outside can be connected with a water pump 32).

In addition, the arrangement position of the hydroentangling device with respect to the mesh base plate 1 can be, but is not limited to, the following two embodiments.

First embodiment

Preferably, the spunlace device is arranged above the mesh base plate 1, and the spunlace device performs spunlace on the plane fabric from top to bottom. Therefore, water sprayed by the spunlace device can directly flow downwards after passing through the plane fabric, and collection and centralized treatment of the water subjected to spunlace are facilitated. Since the first nozzle 2 is also arranged above the mesh base plate 1, when the first nozzle 2 and the spunlace device are in working positions simultaneously and interfere with each other, the first nozzle 2 and the spunlace device can be movably arranged, so that when the first nozzle 2 needs to work, the spunlace device can be moved away, and the first nozzle 2 is moved above the mesh base plate 1; when the hydroentangling device is required to operate, the first nozzle 2 can be moved away and the hydroentangling device moved above the mesh base plate 1.

In order to collect the water after the water jet entangling, it is preferable that a water storage tank 4 for recovering the water sprayed by the water jet entangling is provided under the mesh-type base plate 1, and in order to allow the water after the water jet entangling to be recycled for cost reduction, the water storage tank 4 and the water pump 32 are communicated to supply water to the water pump 32 in a circulating manner, and further, since the water after the water jet entangling generally has impurities, in order to prevent clogging, a soft water treatment means for filtering, such as a filter screen, is provided between the water storage tank 4 and the water pump 32, and in order to rapidly concentrate the water collected in the water storage tank 4, a water suction means for collecting water, such as a sponge, may be provided between the water storage tank 4 and the water pump 32. Of course, it is understood that the water softening device and the water absorbing device can be other devices which are relatively complex and can perform the function of filtering or collecting water.

Second embodiment

As shown in fig. 1 and 5, the hydroentangling device is preferably disposed below the mesh base plate 1, and the hydroentangling device hydroentangles the fibrous material from bottom to top. Therefore, the installation position of the spunlace device is lower, and the spunlace device is conveniently connected with a water source. Since the fiber material is hydroentangled by the hydroentangling device from bottom to top, a part of the water ejected from the hydroentangling device will fall back after entering the plane fabric through the mesh base plate 1 for water hydroentangling, and another part of the water ejected from the hydroentangling device will flow downward due to the obstruction of the mesh base plate 1, therefore, in order to collect the two parts of the water ejected from the hydroentangling device, it is preferable that the printer includes a water storage tank 4 disposed below the mesh base plate 1, and at the same time, the water ejection pipe 31 is disposed in the water storage tank 4 in order to collect the part of the water ejected from the water ejection pipe 31 and directly falling back without reaching the mesh base plate 1. In order to recycle the water after the water jet treatment, so as to reduce the cost, the water storage tank 4 is communicated with the water pump 32 to supply water to the water pump 32 in a circulating manner, as shown in fig. 1 and 5, a water outlet 41 is arranged on the water storage tank 4, and the water stored in the water storage tank 4 can be supplied to the water pump 32 through the water outlet 41. In addition, in order to fix the spray pipe 31, the top surface of the reservoir 4 may be provided with a net structure to which the spray pipe 31 may be tied by a band.

Further, since the water after the water needling is generally contaminated, in order to prevent the clogging, a soft water treatment means for filtering, such as a filter screen, is provided between the water storage tank 4 and the water pump 32, and in order to rapidly collect the water collected in the water storage tank 4, a water suction means for collecting water, such as a sponge, may be provided between the water storage tank 4 and the water pump 32. Of course, it is understood that the water softening device and the water absorbing device can be other devices which are relatively complex and can perform the function of filtering or collecting water.

The number of the water spraying holes H in a unit area can be set according to the strength requirement of the planar fabric, so as to perform water jet punching in different degrees, and in order to enable the mesh-shaped base plate 1 to meet the water jet punching requirements in different degrees, preferably, the aperture ratio of the mesh-shaped base plate 1 is 20% -80%.

In addition, in order to facilitate the determination of the shape of the plane fabric printed by the first ejection head 2, it is preferable that the printer comprises a second ejection head 5 for printing a groove having the outer contour of the plane fabric. The groove with the outer contour of the plane fabric means that the shape enclosed by the inner peripheral wall of the groove is consistent with the outer contour of the plane fabric. In addition, the second showerhead 5 may be a general Fused Deposition Modeling (FDM) showerhead, and the diameter of the orifice of the showerhead 5 may be 0.1-0.5 mm.

Specifically, the second nozzle 5 may be used to print a groove having an outer contour of the planar fabric, that is, the outer contour of the planar fabric to be printed is predetermined by the groove, and then the first nozzle 2 is used to print the planar fabric in the groove, so that the planar fabric printed in the groove is the contour shape of the groove. The printing of the plane fabric can be completed, then the plane fabric can be subjected to spunlace, preferably, the second nozzle 5 can spray water-soluble consumables, so that in the spunlace process, printed grooves can be partially dissolved, in order to be completely dissolved, the grooves can be subjected to water spraying operation, finally, the required plane fabric is obtained, and the customized clothes can be obtained after further processing such as drying, sewing and rough selvedge.

The present invention provides a method for manufacturing a flat fabric for clothing, using the printer described above, the method comprising: step S2, spraying fiber on the reticular bottom plate 1 through the first spray head 2 to print the plane fabric of the clothing; step S4, performing hydroentanglement on the plane fabric on the mesh base plate 1 through the mesh holes on the mesh base plate 1 by using a hydroentanglement device to entangle the fibrous material. The fiber materials sprayed on the reticular bottom plate 1 do not need to be regularly arranged, so that compared with the process of spraying the fiber materials according to a preset track to form regularly arranged filiform materials and laminating the filiform materials layer by layer, the requirement on the precision of equipment is reduced, the operation difficulty is reduced, the printing efficiency of the garment is obviously improved, the cost is reduced to a certain extent, the fiber materials can be entangled through a spunlace process, compared with the mode of bonding each layer of material by self, the strength of the garment is higher, and the user requirements can be better met.

In order to better perform water-inlet spunlace to improve the quality of the plane fabric, preferably, the manufacturing method comprises the following steps: step S3 of performing a pre-wetting treatment and/or an operation of removing bubbles on the plane fabric printed at the step S2, the step S3 being before the step S4. Wherein, the pre-wetting treatment can be carried out by spraying water by a spray can, and the bubble removal can be carried out by pressing by hand.

In order to obtain a planar fabric of a desired shape, preferably, the manufacturing method includes: and step S1, printing a groove with the outer contour of the plane fabric on the mesh base plate 1 through the second nozzle 5, wherein the first nozzle 2 is ejected in the groove to print in the step S2. The groove with the outer contour of the plane fabric means that the shape enclosed by the inner peripheral wall of the groove is consistent with the outer contour of the plane fabric.

The grooves sprayed by the second spray heads 5 are used for determining the outer contour of the plane fabric to be printed, and the first spray heads 2 are convenient to spray the fiber material in the grooves to obtain the plane fabric with the required shape, although in the water-jet process of step S4, the outer contour may be partially dissolved, but in order to completely dissolve the outer contour to obtain the required plane fabric, preferably, the manufacturing method comprises: step S5 of dissolving the groove formed in the step S1, the step S5 being after the step S4. After the required plane fabric is obtained, the customized clothes can be obtained after further processing such as drying, sewing, rough selvedge and the like.

The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, numerous simple modifications can be made to the technical solution of the invention, including combinations of the individual specific technical features in any suitable way.
