Technical Field

The invention relates to a hollow wallboard forming device and a forming method; in particular to a continuous forming device and a forming method of a wood-bamboo hollow forming wallboard with built-in reinforcing ribs.

Background

Wood-structure buildings are the most important form of construction in china for thousands of years. Since the last 60 s, the timber shortage caused by the random felling of forest resources, and together with the concept error, the timber structure building is completely replaced by the reinforced concrete building. At present, wood structure buildings in developed countries generally account for more than 45% of the total building amount, and North America countries achieve more than 85%. The remarkable advantage of developing the wood structure building in these countries is that the forest resources of the countries are extremely abundant. Along with the rapid development of economy in China, the desire of people for a beautiful and comfortable living environment is increasingly urgent, wood structure buildings are rapidly developed again in China, but the development is still stopped due to the constraint of serious shortage of wood resources, and the search for wallboards with similar performance and capable of replacing wood is an extremely urgent task in the field of buildings in China.

The wood-bamboo hollow board (containing the artificial hollow shaving board) has the advantages of high transverse strength, stable thickness and size, low density, heat preservation, heat insulation, sound insulation and raw material saving, and is a possible material for replacing wood and used for wood structural building wallboards. However, the existing production process has inherent defects of low strength in the stamping direction (longitudinal direction) and poor dimensional stability, and cannot produce plates with the thickness of more than 5 cm, and the superior performance of the bamboo-wood veneer can be exerted after the bamboo-wood veneer is coated and subjected to veneering process treatment, so that the production cost is greatly improved, and the production efficiency is reduced. The application of the board is severely restricted, the exertion of the superior performance of the board is restricted, and the board can only be applied to the core boards of various wood doors. In order to enhance the longitudinal compressive strength and the dimensional stability of the wood-bamboo molded hollow slab, people also want to try to add reinforcing ribs in the wood-bamboo molded hollow slab. The existing methods for arranging the reinforcing ribs include two methods, one is to preset a plurality of reinforcing rib holes when the wood-bamboo hollow plate is formed, penetrate the reinforcing ribs into the reinforcing rib holes one by one after the plate is manufactured, and bond the reinforcing ribs with the hole walls of the reinforcing rib holes through a bonding agent. And the other method is to manufacture the molded hollow slab by a flat pressing method, and reinforcing ribs are arranged during manufacturing, so that the aims of improving the strength and the dimensional stability of the slab are fulfilled. Although the reinforcing ribs arranged by the methods improve the longitudinal strength and the dimensional stability of the plate, the methods are either secondary processing or intermittent production, the production efficiency is low, the production cost is greatly improved, and in addition, the plate with the thickness of more than 5 cm cannot be produced technically, and the standard requirements of the wood structure building wall material are far not met, so that the industrialized production cannot be realized.

Detailed Description

The technical solution of the present invention is further specifically described below by way of specific examples.

The outer contour of the wood-bamboo hollow molding wall plate K (shown in figure 25) is a flat rectangular body, wherein holes K1 which are arranged along the length direction and penetrate through two ends of the length direction are formed; in addition, a plurality of reinforcing ribs K2 are arranged, the extending direction of the reinforcing ribs is consistent with the extending direction of the holes, and the arrangement parts of the reinforcing ribs are arranged between every two holes and below the outer surface of the hollow plate, so that better bonding strength with the hollow plate is obtained.

The two setting methods of the reinforcing ribs of the existing wood-bamboo hollow board (one is to preset holes when the wood-bamboo hollow board is formed, then penetrate the reinforcing ribs into the holes one by one after the wood-bamboo hollow board is formed and bond the reinforcing ribs by adopting a bonding agent, and the other is to manufacture the formed hollow board by using a flat pressing method, and simultaneously lay the reinforcing ribs during manufacturing, thereby achieving the purpose of improving the strength and the dimensional stability of the board) are secondary forming or intermittent production processes, so the cost is high, the production efficiency is low, the product performance can not meet the building design standard requirements, and the effect is not good, therefore, the invention carries out brand new design.

The invention provides a continuous built-in forming method of wood-bamboo hollow forming wallboard reinforcing ribs, which comprises the following steps:

1) the punching head reciprocates up and down in the die pressing inner cavity M along a vertical guide rail (the vertical guide rail is vertically arranged on the pillars at the two sides of the rack) under the traction of a power mechanism; meanwhile, the die head and a plurality of inner die forming pipes 4 (the top ends of the inner die forming pipes are fixed on a beam at the upper part of the frame) which are vertically arranged in the die pressing inner cavity and are in sleeve fit with the punching head and a plurality of reinforcing ribs 5 move relatively; the wall part of the mould pressing inner cavity and the wall of the inner mould forming pipe are heated by a heat source heating mechanism to rise the temperature;

the mould pressing inner cavity is defined by two mould pressing plates 12 keeping a parallel distance in the inner cavity thickness direction and two thickness gauges 2 arranged at two ends of the inner cavity in the width direction; the upper end and the lower end of the mould pressing inner cavity are both open.

2) When the punch head moves upwards until a distance is left from the upper end opening of the molding cavity (as shown in fig. 18), the top end inlet (top end feed inlet) of the molding cavity is opened; uniformly applying a certain amount of wood and bamboo crushed aggregates accompanied with glue into the die pressing inner cavity from the top inlet by the feeding device, and supporting the wood and bamboo crushed aggregates by the bottom plate 1 after the wood and bamboo crushed aggregates fall into the die pressing inner cavity;

3) the punching head moves downwards under the traction of the power mechanism to enter the die pressing inner cavity, and the added wood and bamboo crushed aggregates are punched, so that the wood and bamboo crushed aggregates and reinforcing ribs form a tightly combined plate blank (the plurality of reinforcing ribs are uniformly embedded in the plate blank, and each reinforcing rib keeps a distance from the hole and the outer surface of the plate blank), and the plate blank is heated and heated in the die pressing inner cavity; the inner mold forming pipe forms a through hole on the plate blank; a plurality of reinforcing ribs, the plate blank and the bottom plate move downwards for a certain distance (preferably 10-50mm) simultaneously under pressure;

4) the stamping head moves upwards again until the stamping head is separated from the upper end opening of the die pressing inner cavity by a certain distance, and the top end inlet of the die pressing inner cavity is opened again; uniformly applying wood and bamboo crushed aggregates accompanied with glue into the die pressing inner cavity from the top end inlet by the feeding device, and laying the wood and bamboo crushed aggregates on the upper part of the formed plate blank in the previous step after the wood and bamboo crushed aggregates fall into the die pressing inner cavity; the punching head punches the added crushed aggregates, and simultaneously the inner wall of the mould pressing inner cavity and the pipe wall of the inner mould forming pipe perform inside and outside high-temperature heating on the formed plate blank, so that the adhesive is quickly cured when the plate blank is punched and moved at each time.

5) The steps from 3) to 4) are repeated, the wood-bamboo hollow forming wallboard is continuously formed and is gradually led out from the bottom of the mould pressing board to form a product; and cutting the formed wood-bamboo hollow formed wallboard according to the required length.

The invention provides a continuous built-in forming device for wood-bamboo hollow forming wall board reinforcing ribs (as shown in figures 21 to 24): the two mould pressing plates 12 and the two thickness gauges 2 are vertically and fixedly arranged on the frame 18 and enclose a mould pressing inner cavity M with a rectangular cross section, and the upper end and the lower end of the mould pressing inner cavity are communicated with the outside to form an opening; the two mould pressing plates keep parallel distance in the thickness direction of the mould pressing inner cavity, and the two thickness rules are arranged at the two ends of the width direction of the mould pressing inner cavity and used for controlling the thickness of a finished wall plate. The outline of the rectangular cross section is the same as that of the cross section of the wood-bamboo molded hollow slab; a plurality of cylindrical internal mold forming pipes 4 are vertically arranged in a straight shape and fixed in a mold pressing internal cavity (the upper ends of the internal mold forming pipes are fixed with a fixed cross beam 7 of the rack) so as to be used for forming holes of the hollow wallboard, and the size of the internal mold forming pipes and the arrangement mode of the adjacent internal mold forming pipes are the same as the holes of the wood-bamboo formed hollow formed wallboard.

A stamping head 3 which is horizontally arranged and driven by a power mechanism can be positioned in the die pressing inner cavity in a vertically moving way; the stamping head realizes the up-and-down movement in the mould pressing inner cavity through the guide rail mechanisms on the rack support columns at the two ends, and each guide rail mechanism comprises a plurality of vertical guide rails 13 fixed on the rack support columns and a plurality of sliding blocks 14 fixed at four corners of the periphery of the stamping head and in one-to-one sliding fit with the vertical guide rails. A plurality of vertically arranged sliding holes 3.1 are arranged on the punching head, correspond to the inner die forming pipe one by one and are sleeved on the inner die forming pipe in a penetrating way; the periphery of the stamping head is in a shape which is matched with the cross section profile of the mould pressing inner cavity, so that the stamping head and the inner wall of the mould pressing inner cavity cannot be interfered with each other when in moving fit; a plate body of the mould pressing plate and the inner mould forming pipe are internally provided with a heat source heating mechanism (the upper side of the punching head is provided with a fixed cross beam, the fixed cross beam is fixed with all inner mould forming pipes, and the pipes are double-layer; in addition, a feeding device 17 for applying wood and bamboo crushed aggregates to the mould pressing inner cavity is also arranged.

The forming device is similar to the existing wood-bamboo hollow plate forming device.

The improvement of the invention is that: a bottom plate 1 which is horizontally arranged is arranged below the stamping head, and the periphery of the bottom plate is matched with the inner cavity in shape; the bottom plate is also provided with a plurality of sliding holes 1.1 which correspond to the inner mold forming pipes one by one and are sleeved on the inner mold forming pipes one by one through the sliding holes for sliding fit; the peripheral shape of the bottom plate is matched with the cross section profile of the inner cavity. The bottom plate and the stamping head are respectively provided with a plurality of through holes, and a plurality of reinforcing ribs 5 respectively penetrate through the through holes 8 on the stamping head from top to bottom and then are fixed in the through holes of the bottom plate; fig. 13 and 17 show one of the reinforcing rib fixing methods: the reinforcing ribs downwards penetrate through the through holes of the bottom plate and then penetrate through the clamping ring 6 to be pressed and fixed by the clamping ring (after the clamping screw 9 on the clamping ring is screwed in the inner diameter direction, the reinforcing ribs penetrating through the clamping ring are pressed and fixed), so that the reinforcing ribs are fixed on the bottom plate in a single direction (the reinforcing ribs cannot penetrate through the through holes of the bottom plate to move upwards due to the fact that the diameter of the clamping ring is larger than that of the through holes of the bottom plate, and therefore the reinforcing ribs are fixed in a single direction), and the punching force borne by the bottom plate can.

The reinforcing ribs are gradually released by a plurality of releasing mechanisms (conventional mechanisms) arranged on the rack; each release mechanism comprises a spool 10 around which reinforcing bars are wound (one bar per spool), a damping mechanism to damp the rotation of the spool (the purpose of damping is to create a certain tension in the reinforcing bars), and a number of guide wheels 11 for guiding the movement of the reinforcing bars. As the simplest damping mechanism, only a friction plate needs to be fixed on the rack, and one end of the friction plate is pressed against the wheel plate 10.1 of the spool to generate friction. When the punching head moves downwards to punch the wood and bamboo crushed aggregates, the pressure applied to the bottom plate exceeds the damping force, and the reinforcing ribs are driven to move downwards for a certain distance (the reinforcing ribs are naturally released for a certain distance); thereby the reinforcing rib always keeps certain tension.

The inner wall of the mould pressing inner cavity is also suitable for the surface structure of the wood-bamboo hollow forming wallboard; when the surface of the hollow wood-bamboo shaped wallboard is designed with a plurality of grooves K3 which are longitudinally arranged, the inner cavity wall surface of the rectangular cross section is provided with corresponding bulges so that the hollow wood-bamboo shaped wallboard obtained by mould pressing conforms to the design, thereby preparing the wallboard with the direct surface decoration effect)

The driving mode of the punching head is the prior art. As can be seen from the figure: the two ends of the stamping head extend outwards to the outside of the frame and are driven by a power mechanism arranged on the frame. The power mechanism is a crank-slide rod mechanism driven by a motor 19 through a belt wheel mechanism; the crank is a connecting rod 15 eccentrically hinged on a punching flywheel 16 (a rotating shaft of the punching flywheel is shielded by an upper cross beam 7 in fig. 24), the bottom end of the connecting rod is hinged with the end part of the punching head, the rotating kinetic energy of the punching flywheel is converted into linear punching kinetic energy, and therefore the punching head is driven to slide up and down along a vertically arranged guide rail to punch the bamboo and wood crushed aggregates entering the die pressing inner cavity.

The reinforcing ribs are preferably flexible reinforcing ribs impregnated with thermosetting resin, and can be metal wire ropes, strong fiber wire ropes, particularly aramid fiber reinforcing ropes.

The charging device 17 shown in fig. 23 comprises an outer shell 17.1 and an inner shell 17.2; the outer shell 17.1 forms the outer wall of the feeding device, and the lower punching head is covered by the inner shell to isolate the punching head from the wood and bamboo crushed aggregates. A funnel-shaped output port with a large upper part and a small lower part is formed between the outer shell and the inner shell; the output port is aligned with the top opening of the mould pressing inner cavity, and when the punching head moves upwards to open the top inlet, the wood and bamboo crushed aggregates can be applied to the mould pressing inner cavity; the amount of applied wood or bamboo particles is determined by the size of the top inlet (by the distance the punch head has moved upward).
