A fiberboard lamination processing device

Abstract

The present invention relates to a fiberboard lamination processing device, which includes a forming base, a U-shaped frame, a lifting cylinder, a lamination mold, a connecting cylinder and an output mechanism. The U-shaped frame is installed at the upper end of the forming base. A lifting cylinder is connected between the U-shaped frame and the lamination mold, and the lamination mold is connected to the output mechanism through the connecting cylinder. The present invention can solve the problem that the glue is injected first, and partial solidification may occur during the subsequent lamination process. In the case of glue solidification, it is difficult to further extrude this part of the area subsequently. Moreover, traditional glue is difficult to be quickly and evenly distributed in the raw material layer after injection, resulting in different adhesiveness in different areas of the raw material layer. The area with less glue has a lower degree of cohesion and is extremely easy to be damaged under accidental external collisions in the later stage, thus reducing the quality of the finished product, etc.

Description

Technical Field

[0001] The present invention relates to the technical field of fiberboard processing, and particularly relates to a fiberboard laminating processing device. Background Art

[0002] With the rapid development of China's economy and the continuous improvement of the urbanization rate, fiberboard products with stable quality, high environmental protection level, meeting differentiated demands, and having safety flame retardant functions have broad market space. In the future, the rapid development of industries such as real estate, furniture, interior decoration, and packaging in China, as well as the completion and production of fast-growing industrial timber raw material bases, will drive the steady growth of the demand and export volume of fiberboards. The proportion of fiberboard products in the total production of wood-based panels will also increase significantly. Fiberboard is a wood-based panel formed by the interweaving of wood cellulose fibers and using its inherent adhesive properties. During the manufacturing process, it needs to be laminated and formed. In the traditional lamination process, glue is injected into the raw material layer and then laminated. However, this lamination method often encounters some problems:

[0003] The prior injection of glue may cause partial solidification during the subsequent lamination process. In the case of glue solidification, it is difficult to further extrude this part of the area subsequently. Moreover, the traditional glue is difficult to be quickly and evenly distributed in the raw material layer after injection, resulting in different adhesiveness in different areas of the raw material layer. The area with less glue has a lower degree of cohesion and is extremely easy to be damaged under accidental external collisions later, thus reducing the quality of the finished product. Summary of the Invention

[0004] (I) Technical Solution

[0005] In order to achieve the above object, the present invention adopts the following technical solution: A fiberboard laminating processing device, including a forming base, a U-shaped frame, a lifting cylinder, a laminating die, a connecting cylinder, and an output mechanism. The upper end of the forming base is provided with a U-shaped frame. A lifting cylinder is connected between the U-shaped frame and the laminating die. The laminating die is connected to the output mechanism through a connecting cylinder.

[0006] The laminating die includes a gravity block. The top end of the lifting cylinder is provided with a gravity block. A vertical rod is slidably arranged at the lower end of the gravity block. The lower end of the vertical rod is installed on the laminating plate.

[0007] The output mechanism includes a connecting plate. A connecting cylinder is connected between the gravity block and the connecting plate. A conveying cavity is opened inside the connecting plate. The conveying cavity is communicated with the output port of a conveying pump installed on the connecting plate. The input port of the conveying pump is inserted into a storage frame installed on the connecting plate through a hose. A power supply module located above the connecting plate is connected in series with a driving cylinder. The power supply module is installed on the gravity block through a fixing frame. The top end of the driving cylinder passes through the gravity block and is connected to the laminating plate. An embedding pipe is connected and installed at the lower end of the conveying cavity.

[0008] The described power supply module includes an insulating frame, which is installed on the connecting plate. Inside the insulating frame, a power supply, a contact unit, and a driving cylinder are installed in a loop shape, and the power supply, the contact unit, and the driving cylinder are connected by wires. A contact block corresponding to the contact unit is installed on the connecting plate.

[0009] Among them, the described forming base includes a forming frame. A heating bottom plate is installed at the bottom of the forming frame. An inner groove is opened at the lower end of the forming frame. A pushing cylinder is connected between the inner groove and the heating bottom plate. After lamination, the heating bottom plate is driven to rise by the pushing cylinder, so as to push out the formed fiber board blank. An inlet groove is opened at the front end of the forming frame. An inlet block is slidably arranged back and forth in the inlet groove. The inlet block is pulled forward, and raw materials are poured into the inlet groove. Then the inlet block is pushed back to its original position, so that the raw materials completely enter the forming frame.

[0010] Among them, heating wires are arranged inside the heating bottom plate. Heating is beneficial to the solidification of the glue, and the increased temperature will not burn the surface of the raw material layer. A handle is arranged at the front end of the inlet block, which is beneficial to the pushing of the inlet block.

[0011] Among them, the upper and lower layers of the laminate are made of steel material. The upper and lower steel material layers improve the hardness. The middle part of the laminate is a rubber layer, and the rubber layer provides a certain buffer area.

[0012] Among them, the contact unit includes a first conductive block, which is fixedly installed on the insulating frame. A second conductive block located below the first conductive block is slidably arranged up and down on the insulating frame, and both the first conductive block and the second conductive block are connected to the wire.

[0013] Among them, the position of the contact block corresponds to that of the second conductive block, and the contact block is made of rubber material, which plays an insulating effect.

[0014] Among them, spray holes are symmetrically opened at the left and right ends of the embedding tube for the spraying of glue. The lower end of the embedding tube is a sealed structure. When the lower end surface of the laminate descends for the second time and is at the same horizontal plane as the lower end surface of the embedding tube, the formed lower end surface is a completely sealed plate surface, which is beneficial to pressing. At the same time, it also ensures the possibility that the glue will not accidentally leak out.

[0015] (II) Beneficial effects

[0016] 1. In the fiberboard laminating processing device of the present invention, the evenly distributed embedding tubes are inserted into the raw material layer from top to bottom during the first lamination, so that the glue is evenly injected into each area of the raw material layer, improving the distribution area of the glue. After the injection is completed, the embedding tubes rise to an appropriate height and then perform secondary lamination until the lower end surfaces of the embedding tubes are at the same horizontal plane position as the lower end surface of the laminate. At this time, the secondary lamination ends. The two-layer laminations improve the extrusion density and also squeeze and fill the holes left by the embedding tubes inserted into the raw material layer. The double-pressure extrusion and the even injection of glue improve the condensation degree of each area of the fiberboard blank and improve the finished product quality.

[0017] 2. In the fiberboard laminating processing device of the present invention, the laminating die is designed with a double-layer plate structure, so that after the gravity block and the laminate synchronously descend, the laminate separately performs secondary descending lamination.

[0018] 3. In the fiberboard laminating processing device of the present invention, the output mechanism adopts the design concept of structural linkage. After the embedding tubes rise to the designated position, the laminate descends until its lower end surface is at the same horizontal plane as the lower end surface of the embedding tubes and then stops descending. Moreover, the design of the multi-point even distribution of the embedding tubes improves the even distribution after the glue injection. The synchronization of the glue injection and the lamination avoids the premature solidification of the glue. BRIEF DESCRIPTION OF THE DRAWINGS

The feed block 14 is pulled forward and the raw material is poured from the feed trough. Then the feed block 14 is pushed back and reset, so that the raw material completely enters the molding frame 11. A heating wire is provided inside the heating base plate 12. Heating is conducive to the solidification of the glue, and the increased temperature will not burn the surface of the raw material layer.

[0028] The laminating mold 4 includes a gravity block 41, and the ejection end of the lifting cylinder 3 is equipped with the gravity block 41. The lower end of the gravity block 41 is slidably provided with an upright rod 42, and the lower end of the upright rod 42 is installed on a laminate 43. The upper and lower layers of the laminate 43 are made of steel material. The upper and lower layers of steel material have improved hardness.

[0029] The output mechanism 6 includes a connecting plate 61, a connecting cylinder 5 is connected between the gravity block 41 and the connecting plate 61, a conveying cavity is provided inside the connecting plate 61, the conveying cavity is communicated with the output port of the conveying pump 62 installed on the connecting plate 61, the input port of the conveying pump 62 is inserted into the storage frame 63 installed on the connecting plate 61 through a hose, a power supply module 64 located above the connecting plate 61 is connected in series with the driving cylinder 65, the power supply module 64 is installed on the gravity block 41 through a fixing frame 66, the ejection end of the driving cylinder 65 passes through the gravity block 41 and is connected to the laminate 43, the lower end of the conveying cavity is connected and installed with an embedded tube 67, the left and right ends of the embedded tube 67 are symmetrically provided with spray holes, the lower end of the embedded tube 67 is a sealing structure for the spraying of glue, when the lower end surface of the laminate 43 is at the same horizontal plane after the laminate 43 is lowered for the second time, the lower end surface formed by the two is in a completely sealed board surface, which is conducive to pressing, and at the same time, it also ensures the possibility that the glue will not accidentally leak out.

[0030] Specifically, for the first lamination, the lamination mold 4 is driven by the lifting cylinder 3 to descend so as to laminate the raw materials. During the descending process, the glue liquid in the storage frame 63 is output through the delivery pump 62 and then evenly injected into each area of the raw material layer. For the second lamination, when the lower end of the embedding tube 67 abuts against the heating bottom plate 12, the lamination mold 4 stops descending. At this time, the connecting plate 61 is driven to rise by the connecting cylinder 5, and the embedding tube 67 rises synchronously. When the lower end of the rising embedding tube 67 is 3 cm away from the upper surface of the raw material layer, it stops rising together with the connecting plate 61. At this time, the power supply module 64 and the driving cylinder 65 form a complete circuit, and the power supply module 64 supplies power to the driving cylinder 65 to drive the laminating plate 43 to descend, so as to further laminate the extruded raw material layer (on the one hand, the density after extrusion is improved, and on the other hand, the holes left in the raw material layer after the embedding tube 67 moves away are compacted). It stops descending when the lower end surface of the descending raw material layer is at the same horizontal plane as the lower end of the embedding tube 67, and the lamination is completed.

[0031] The power supply module 64 includes an insulating frame 641. The insulating frame 641 is installed on the connecting plate 61. A power supply 642, a contact unit 643 and a driving cylinder 65 are installed in a loop inside the insulating frame 641, and the power supply 642, the contact unit 643 and the driving cylinder 65 are connected by a wire 644. A contact block 645 corresponding to the contact unit 643 is installed on the connecting plate 61. The contact block 645 corresponds to the position of the second conductive block 6432, and the contact block 645 is made of rubber material, which plays an insulating role. The contact unit 643 includes a first conductive block 6431. The first conductive block 6431 is fixedly installed on the insulating frame 641.

Specifically, during the ascending process of the connecting plate 61, when the contact block 645 squeezes the second conductive block 6432 into contact with the first conductive block 6431, the power supply module 64 and the driving cylinder 65 form a complete circuit, and the power supply module 64 supplies power to the driving cylinder 65.

[0032] The implementation principle of this embodiment is as follows:

[0033] Push the raw materials into the forming frame 11 to make them evenly distributed in the forming frame 11;

[0034] For the first lamination: The lamination mold 4 is driven by the lifting cylinder 3 to descend so as to laminate the raw materials. At the same time, the glue liquid in the storage frame 63 is output through the delivery pump 62 and then evenly injected into each area of the raw material layer;

[0035] Secondary lamination: When the lower end of the embedding tube 67 abuts against the heating base plate 12, the lamination die 4 stops descending. At this time, the connecting cylinder 5 drives the connecting plate 61 to rise, and the embedding tube 67 rises synchronously. When the lower end of the rising embedding tube 67 is 3 cm away from the upper surface of the raw material layer, it stops rising together with the connecting plate 61. At this time, the power supply module 64 supplies power to the driving cylinder 65 to drive the laminating plate 43 to descend, so as to further laminate the extruded raw material layer. When the lower end surface of the descending raw material layer is at the same horizontal plane as the lower end of the embedding tube 67, it stops descending, and the lamination is completed;

[0036] The lifting cylinder 3 drives the lamination die 4, the connecting cylinder 5 and the output mechanism 6 to rise as a whole. After that, the output mechanism 6 adjusts and resets alone. Then, the pushing cylinder 13 drives the heating base plate 12 to rise to eject the formed fiberboard blank, and the fiberboard blank is taken out.
