Description

Technical Field

[0001] The invention relates to the field of plywood, in particular to a rapid hot pressing and shaping device for producing plywood. Background Art

[0002] The main raw materials of plywood are wood and adhesive. The wood should be of good quality and fully dried to ensure the quality and stability of the plywood. Adhesives usually use phenolic resin, urea-formaldehyde resin or phenolic urea-formaldehyde resin, etc. According to different types of adhesives and production processes, the adhesive is mixed with water, hardener, etc. in a certain proportion to achieve a certain viscosity and fluidity. The treated wood is cut according to certain specifications and sizes, and the cut wood is layered in a certain order and direction. Hot pressing can effectively avoid the problems of bubbling and local degumming of plywood. After hot pressing, the slab needs to be left to cool for about 15 minutes to ensure that the product structure is stable, the strength is high, and warping and deformation are avoided.

[0003] After searching, the patent with application number CN202011308041.9 discloses a pressing device for plywood processing and a hot press equipment for plywood production. The working principle of the hot press is to use pulse heating pressure to form a low-resistance surface on the welding head, so that the current flows through the workpiece with minimum resistance and quickly heats the welding head. The hot press can adopt the hydraulic principle to ensure highly balanced pressure application, and has the functions of automatic pressurization, pressure maintenance and pressure compensation.

[0004] In the production process of plywood, three or more layers of boards are usually combined and hot-pressed to form plywood. When the three layers of boards are combined, the boards need to be coated with glue. In the process of coating glue, the staff usually brushes glue manually. After one side of the board is coated with glue, another board is pasted, and then the other side of the board is coated with glue, which seriously delays the subsequent shaping time of the plywood. At the same time, before hot pressing, there may be gaps between the multi-layer boards after coating with glue. When hot pressing in a hot press, the glue distribution and density inside the board are uneven during one-time hot pressing, which increases the time of hot pressing. Therefore, a rapid hot pressing shaping device for plywood production is proposed. Summary of the invention

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a rapid hot pressing and shaping device for plywood production.

[0023] In a typical implementation of the present application, Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a rapid hot pressing and shaping device for producing plywood comprises: A workbench 1 is provided with a top frame 2 for providing a platform for working; The side-placed adhesive component 3 is arranged above the workbench 1 and is used for bonding and conveying the plate. The side-placed adhesive component 3 includes two placement frames 5 arranged on the workbench 1. The placement frames 5 are provided with negative pressure covers 7 and conveying rollers 10. Side plates 13 are provided on the sides of the placement frames 5. The negative pressure covers 7 and conveying rollers 10 are in contact with one side of the side plates 13. A pushing cylinder 4 is fixedly installed on the side of the top frame 2. The output end of the pushing cylinder 4 is fixedly connected to the side of the placement frame 5. A negative pressure fan 6 is installed on the side of the placement frame 5. The negative pressure fan 6 is connected to the negative pressure cover 7. A plurality of conveying shafts 9 are rotatably installed in the placement frame 5. The conveying rollers 10 are fixedly sleeved on the conveying shafts 9. A conveying motor 11 is provided on the top of the placement frame 5. The output end of the conveying motor 11 is fixedly connected to the end of a conveying shaft 9. A conveying drive belt 12 is connected between two adjacent conveying shafts 9. A horizontal plate 8 is installed on the side of the placement frame 5.

[0024] During the production process of plywood, more boards need to be glued together. The side boards 13 and the middle boards 20 that need to be glued are transported by the conveyor belt, and then the staff place the side boards 13 on one side of the two placement frames 5 respectively, and the middle board 20 is placed under the U-shaped placement block 19. When placing the side boards 13, the negative pressure fan 6 on the side placement adhesion component 3 is started to run, and the negative pressure cover 7 can generate negative pressure suction on the side boards 13, and the side boards 13 will not fall down after being placed.

[0025] As a preferred implementation in this embodiment, Figure 2 and Figure 6 As shown, a double-sided gluing component 25 is arranged on the top frame 2, and is used for performing double-sided gluing operations on the side panels 13 on both sides. The double-sided gluing component 25 includes a moving frame 26 fixedly installed on the bottom of the top frame 2, and a screw motor 27 is fixedly installed on the side of the moving frame 26. The output end of the screw motor 27 extends into the moving frame 26, and an L-shaped screw moving plate 28 is installed on the moving frame 26. The side of the L-shaped screw moving plate 28 is connected to an air inlet pipe 29 and a liquid inlet pipe 31, the side of the air inlet pipe 29 is connected to a plurality of blowing nozzles 30, the side of the liquid inlet pipe 31 is connected to a plurality of nozzles 32, and a brush roller 33 is rotatably installed on the side of the L-shaped screw moving plate 28.

[0026] After the plate is placed, the screw motor 27 on the double-sided glue coating component 25 is started to run. The rotation of the screw can drive the L-shaped screw moving plate 28 to move back and forth. During the forward movement, the air inlet pipe 29 and the liquid inlet pipe 31 are both opened. The air inlet pipe 29 is connected to an external blower, and the liquid inlet pipe 31 is connected to an external bonding solution pump. The gas delivered by the air inlet pipe 29 is blown out through a plurality of blowing nozzles 30. The blowing nozzles 30 are arranged at an angle, and can blow air to the side plates 13 on both sides. The side plates 13 have a surface. The dust on the surface can be blown away to avoid the influence of dust on gluing. The glue delivered by the liquid inlet pipe 31 is sprayed out from multiple nozzles 32. The nozzles 32 on both sides spray glue onto the two side plates 13 respectively to achieve uniform glue spraying. After glue spraying, it will be rolled and brushed by the brush roller 33 at the rear, so that the sprayed glue can be more evenly applied to the side plate 13. One movement can be used to apply glue to two plates at the same time. Compared with traditional manual gluing, it is more convenient and saves a lot of gluing time. After gluing, the L-shaped screw moving plate 28 returns to its position.

[0027] As a preferred implementation in this embodiment, Figure 1 , Figure 5 , Figure 7 and Figure 8 As shown, the middle placing component 14 is arranged between the two placing frames 5 for stably placing the plate in the middle, the middle placing component 14 includes a top plate 15 installed at the bottom of the top frame 2, a U-shaped placing block 19 is installed below the top plate 15, a middle plate 20 is arranged between the U-shaped placing block 19 and the workbench 1, an insertion tube 16 is fixedly installed at the bottom of the top plate 15, an insertion rod 17 is fixedly installed at the top of the U-shaped placing block 19, the top end of the insertion rod 17 extends into the insertion tube 16, a return spring 18 is fixedly installed between the top end of the insertion rod 17 and the top wall of the insertion tube 16, a rotating seat 21 is fixedly installed on the top of the placing frame 5, a pushing top rod 22 is rotatably installed on the rotating seat 21, a bottom supporting block 23 is fixedly installed on the side of the rotating seat 21, the pushing top rod 22 is located on the bottom supporting block 23, an L-shaped pushing top block 24 is fixedly installed on the top of the U-shaped placing block 19, and the L-shaped pushing top block 24 is adapted to the pushing top rod 22.

[0028] Starting the pushing cylinders 4 on both sides can drive the placement frames 5 on both sides to approach each other. When the placement frames 5 move, they will drive the pushing push rods 22 to move. When the placement frames 5 are about to approach the middle plate 20, the pushing push rods 22 will contact the L-shaped pushing push blocks 24. Under the action of the pushing, the U-shaped placement blocks 19 will move up and drive the insertion rods 17 to move up, compressing the reset springs 18. With continuous pushing, the U-shaped placement blocks 19 are separated from the middle plate 20. At the same time, the side plates 13 on both sides will contact, fit and squeeze the middle plate 20. After more plates are fitted, a piece of plywood is formed, forming a preliminary fitting and pressing. At this time, the conveying motor 11 is started and the negative pressure fan 6 is stopped. Under the action of multiple conveying belts 12, multiple conveying shafts 9 are driven to rotate. After multiple conveying rollers 10 rotate synchronously, they will drive the plywood to move to one side, so that the plywood can be conveyed to the upper position of the falling adjustment component 34.

[0029] As a preferred implementation in this embodiment, Figure 3 , Fig. 9 and Fig.10 As shown, a drop adjustment component 34 is arranged at one side of the placement frame 5, and is used for preparing the glued plate before falling. The drop adjustment component 34 includes a bucket-shaped drop hole 35 opened on the top of the workbench 1, and an L-shaped adjustment hole 36 is opened on the side wall of the bucket-shaped drop hole 35. An L-shaped adjustment plate 37 is movably installed on the L-shaped adjustment hole 36, and a plurality of extrusion springs 38 are fixedly installed between the L-shaped adjustment plate 37 and the inner wall of the L-shaped adjustment hole 36. An adjustment push rod 39 is fixedly installed on the side of a placement frame 5, and the adjustment push rod 39 is adapted to the L-shaped adjustment plate 37. Two rows of several shafts are arranged on the top of the workbench 1, and anti-tilt rollers 40 are rotatably installed on both rows of several shafts.

[0030] When the placement frame 5 moves, it will drive the adjustment push rod 39 to move, thereby pushing the L-shaped adjustment plate 37. When the side plate 13 and the middle plate 20 are in contact, the L-shaped adjustment plate 37 will block the bucket-shaped drop hole 35, and the plywood transported to one side will be located above the L-shaped adjustment plate 37. The anti-tilt roller 40 can form a protective effect from both sides. After the plywood is delivered to one side, it pushes the cylinder 4 to return to its position, driving the placement frame 5 to return to its position. At this time, the adjustment push rod 39 will separate from the L-shaped adjustment plate 37. Under the push of the extrusion spring 38, the L-shaped adjustment plate 37 will also return to its position, the bucket-shaped drop hole 35 will open, and the plywood located above will fall.

[0031] As a preferred implementation in this embodiment, Figure 3 and Fig.11As shown, the pre-pressing component 41 is arranged below the drop regulating component 34, and is used for pre-pressing the glued plate. The pre-pressing component 41 includes two sets of mounting plates 42 fixedly mounted on the bottom of the workbench 1, and a plurality of rotating pressure rollers 45 are rotatably mounted between the two sets of mounting plates 42. The two sets of rotating pressure rollers 45 are arranged in a V-shape, and a rotating shaft 43 is rotatably mounted between the two sets of mounting plates 42. The plurality of rotating pressure rollers 45 are fixedly sleeved on the rotating shaft 43. A driving motor 44 is fixedly mounted on the side of the mounting plate 42, and the output end of the driving motor 44 is fixedly mounted on the end of a rotating shaft 43. A pressure roller transmission belt 46 is arranged between two adjacent rotating shafts 43.

[0032] The rotating pressure rollers 45 on both sides are arranged in a V-shape, which can achieve a pre-compression effect on the plywood from both sides. After the driving motor 44 is running, it cooperates with the operation of multiple pressure roller transmission belts 46. After the multiple rotating pressure rollers 45 rotate, they can continuously squeeze the glued board to form a secondary compression. During this compression, the internal air can be effectively removed, reducing the subsequent compression time.

[0033] As a preferred implementation in this embodiment, Figure 2 , Fig.12 , Fig.13 and Fig.14 As shown, a hot pressing component 47 is arranged below the workbench 1 and is used to perform hot pressing on the glued plates. The hot pressing component 47 includes a hot pressing machine 48 arranged below the workbench 1. A plurality of hot pressing plates 49 are arranged in the hot pressing machine 48. A connecting chain 53 is connected between two adjacent hot pressing plates 49. A pulling rope 54 is fixedly connected to the side of the hot pressing plate 49 located at the outermost side. One end of the pulling rope 54 extends to the outside of the hot pressing machine 48 and is connected to a positioning bolt 55. A bolt groove 56 is arranged on the outside of the hot pressing machine 48. The positioning bolt 55 is threadedly installed in the bolt groove. 56, a hydraulic cylinder 50 is arranged on the side of the hot press 48, the output end of the hydraulic cylinder 50 extends into the hot press 48 and is adapted to the outermost hot pressing plate 49, a plurality of bottom rollers 59 are rotatably mounted on the bottom of the hot press 48, a guide column 51 is fixedly mounted on the bottom and side of the hot press 48, a plurality of hot pressing plates 49 are fixedly mounted on the bottom and side of the hot press 48, the guide blocks 52 are slidably sleeved on the guide columns 51, a bottom conveying frame 57 is arranged below the hot press 48, and a telescopic cylinder 58 is arranged between the bottom conveying frame 57 and the hot press 48.

[0034] After pre-pressing, the plywood continues to fall into the hot press 48 below. In the initial stage, the pulling rope 54 of the multiple hot pressing plates 49 in the hot press 48 is in a tensioned state. Under the involvement of the connecting chain 53, the multiple hot pressing plates 49 are in an open state. The positioning bolts 55 are threadedly installed in the bolt grooves 56, which can position the opened hot pressing plates 49. After a plywood falls, the telescopic cylinder 58 is operated to push the hot press 48 to move a short distance, so that the next plywood can fall into the pressing gap of another hot pressing plate 49. After repeating this step, there are plywoods between the two adjacent hot pressing plates 49, and then the hot pressing step is started (the hot pressing step is the existing hot pressing equipment), and the plywood is hot pressed. Through the previous preliminary pressing and secondary extrusion, the plywood is extruded multiple times to avoid uneven glue distribution and uneven density inside the board. When hot pressing, the hot pressing time can be reduced while ensuring the performance of the board.

[0035] Working principle of the present invention: During the production of plywood, the staff will place the side panels 13 on one side of the two placement frames 5, and the middle panel 20 will be placed under the U-shaped placement block 19. The negative pressure fan 6 will be operated to generate negative pressure to attract the side panels 13 so that they will not fall down. After the panels are placed, the double-sided glue coating component 25 will be started to operate, driving the L-shaped screw moving plate 28 to move back and forth. The gas delivered by the air inlet pipe 29 will be blown out through multiple blowing nozzles 30, and the dust on the surface of the side panel 13 can be removed. The glue liquid delivered by the liquid inlet pipe 31 is sprayed out from multiple nozzles 32, and the nozzles 32 on both sides spray glue onto the two side plates 13 respectively to achieve uniform glue spraying. After the glue spraying, it will be rolled and brushed by the brush roller 33 at the rear, so that the sprayed glue liquid can be more evenly applied to the side plates 13. One movement can be used to apply glue to two plates at the same time, which is more convenient than traditional manual gluing and saves a lot of gluing time. After the gluing is completed, the L-shaped screw moving plate 28 returns to its original position; Start the pushing cylinders 4 on both sides to run, the placement frames 5 on both sides approach each other, the U-shaped placement block 19 will move up, and with continuous pushing, the U-shaped placement block 19 will separate from the middle plate 20, and at the same time, the side plates 13 on both sides will contact and fit with the middle plate 20 and squeeze, and more plates will be fitted to form a plywood, forming a preliminary fitting and compaction, then start the conveying motor 11 to run, and at the same time stop the negative pressure fan 6 to run, under the action of multiple conveying belts 12, drive multiple conveying shafts 9 to rotate, and multiple conveying rollers 10 will drive the plywood to move to one side after synchronous rotation, so that the plywood can be conveyed to the upper position of the falling adjustment component 34, and the pushing cylinder 4 will run back to its position, driving the placement frame 5 to return to its position, at this time, the adjusting push rod 39 will separate from the L-shaped adjustment plate 37, and the L-shaped adjustment plate 37 will also return to its position, the bucket-shaped drop hole 35 will open, and the plywood located above will fall; The pre-pressing component 41 is set to achieve a pre-pressing effect on the plywood from both sides to form a secondary pressing. The pressing can effectively exclude the internal air and reduce the time of subsequent pressing. The pre-pressed plywood continues to fall into the hot press 48 below. After a plywood falls, the hot press 48 moves a short distance to facilitate the next plywood to fall into the pressing gap of another hot pressing plate 49. After repeating this step, there are plywoods between the two adjacent hot pressing plates 49, and then the hot pressing step is started to perform hot pressing operations on the plywood. Through the previous preliminary pressing and secondary pressing, the plywood is pressed multiple times to avoid uneven glue distribution and uneven density inside the board. When hot pressing is performed, the hot pressing time can be reduced while ensuring the performance of the board.

[0036] It should be noted that: The following proposed in this application: the pushing cylinder 4, the negative pressure fan 6, the conveying motor 11, the screw motor 27, the driving motor 44, the hot press 48, the hydraulic cylinder 50, and the telescopic cylinder 58 are all prior arts, and their specific structures, functions and usages are not described in detail in this article.
