Description

Technical Field

[0001] This utility model relates to the field of particleboard production technology, and in particular to a particleboard hot pressing device. Background Technology

[0002] Particleboard, also known as particleboard, is a type of engineered wood product made by cutting wood and other raw materials into shavings of a certain size (length, width, and thickness), drying them, adding adhesives, hardeners, and waterproofing agents, and then pressing them together under temperature and pressure. The advantages of particleboard include its uniform structure, excellent processing performance, and ability to be processed into large-format boards. It is a high-quality raw material for furniture making, and hot pressing is a crucial step in the particleboard production process.

[0003] Utility model patent CN216328967U discloses a particleboard hot pressing device. This device accelerates airflow across the particleboard surface through the relative flow of two cooling mechanisms. Simultaneously, the operation table incorporates a top plate and copper pipes to rapidly cool the particleboard, thereby improving hot pressing efficiency. However, the top plate directly participates in cooling the particleboard, resulting in a relatively low temperature. This leads to a significant temperature difference between the top and bottom of the particleboard being pressed, affecting the forming quality and causing poor adhesion at the bottom. Utility Model Content

[0004] The purpose of this application is to provide a particleboard hot pressing device to solve the problem mentioned in the background art where the top plate directly participates in the cooling of the particleboard, resulting in a low temperature. This leads to a large temperature difference between the top and bottom of the particleboard being hot-pressed when the top plate is used for the next particleboard hot pressing, which affects the forming quality of the particleboard and causes poor adhesion at the bottom of the particleboard.

[0005] To achieve the above objectives, this application provides the following technical solution: a particleboard hot pressing device, comprising a base, a support plate and a fixing plate mounted on the top of the base, a hydraulic cylinder mounted on the top of the fixing plate, a heat insulation plate fixedly mounted on the output end of the hydraulic cylinder, a hot pressing plate fixedly mounted on the bottom of the heat insulation plate, a traction assembly mounted on the base, a carrier plate mounted on the traction assembly, and the traction assembly being used to move the carrier plate, a first water tank, a second water tank and a water pump mounted on the top of the carrier plate, a connecting pipe fixedly connected between the first water tank and the second water tank, the inlet of the water pump being connected to the first water tank, a height adjustment assembly mounted on the top of the first water tank and the second water tank, two water supply hard pipes mounted on the height adjustment assembly, a water guide hose fixedly connected between the outlet of the water pump and one of the water supply hard pipes, a return hose fixedly connected between the second water tank and the other water supply hard pipe, a rotary joint mounted on the other end of the water supply hard pipe, a water-cooled roller mounted between the two rotary joints, and the height adjustment assembly being used to adjust the height of the water-cooled roller.

[0006] Furthermore, a water injection pipe is fixedly connected to the top of the first water tank, and a valve is installed on the water injection pipe.

[0007] Furthermore, four rollers are installed at the bottom of the carrier plate, and the four rollers are respectively located on both sides of the traction assembly.

[0008] Furthermore, the height adjustment assembly includes a support plate, with the first and second water tanks both installed at the bottom of the support plate. Two electric push rods are mounted on the support plate, and fixed blocks are fixedly installed at the output ends of the electric push rods. The two fixed blocks are respectively fixedly sleeved on the two water supply pipes.

[0009] Furthermore, the traction assembly includes a rectangular frame plate, which is mounted on a base. A lead screw is rotatably connected between the left and right inner walls of the rectangular frame plate via bearings. A carrier block is threaded onto the lead screw. The carrier plate is fixedly mounted on the top of the carrier block, and the carrier block slides against the inner wall of the rectangular frame plate.

[0010] Furthermore, a drive motor is installed on the left side of the rectangular frame plate, and the lead screw is driven by the drive motor.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this invention, a hydraulic cylinder pushes a hot press plate to hot press the particleboard placed on a pallet into shape. The hydraulic cylinder then pulls the hot press plate to move up and reset. A height adjustment component adjusts the height of the water-cooling roller, allowing the water-cooling roller, pulled by the traction component, to roll back and forth on the top of the hot-pressed particleboard. A water pump drives the water in the first water tank, the second water tank, and the water-cooling roller to circulate. The cooling water flowing through the water-cooling roller cools the particleboard, greatly improving the cooling efficiency after hot pressing and increasing the processing efficiency of the particleboard. This also prevents the pallet from being over-cooled, which could affect the subsequent processing of the particleboard.

[0013] In this invention, the height of the fixing block can be adjusted by using an electric push rod, so that the height of the water supply pipe on the fixing block can be adjusted accordingly. In this way, the height of the water-cooling roller can be appropriately adjusted according to the thickness of the particleboard after hot pressing, ensuring that the water-cooling roller can effectively contact the particleboard after hot pressing, which facilitates the cooling of the particleboard after it is formed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example: Reference Figure 1-4 The illustrated particleboard hot pressing device includes a base 1, a support plate 2 and a fixing plate 3 mounted on the top of the base 1, a hydraulic cylinder 4 mounted on the top of the fixing plate 3, a heat insulation plate 5 fixedly mounted on the output end of the hydraulic cylinder 4, and a hot pressing plate 6 fixedly mounted on the bottom of the heat insulation plate 5. The hot pressing plate 6 is located directly above the support plate 2. A traction assembly is mounted on the base 1, and a carrier plate 7 is mounted on the traction assembly, which is used to move the carrier plate 7. A first water tank 8, a second water tank 9, a water pump 10, and a chiller are mounted on the top of the carrier plate 7. The chiller is used to cool the water in the second water tank 9. A water injection pipe 16 is fixedly connected to the top of the first water tank 8, and a valve is mounted on the water injection pipe 16. Water can be added to the first water tank 8 through the water injection pipe 16. The first water tank 8 and the second water tank 9 are fixedly connected by a connecting pipe. The water inlet of the water pump 10 is connected to the first water tank 8. The top of the first water tank 8 and the second water tank 9 are equipped with a height adjustment component. Two water supply hard pipes 11 are installed on the height adjustment component. The water outlet of the water pump 10 is fixedly connected to one of the water supply hard pipes 11 by a water guide hose 12. The second water tank 9 is fixedly connected to the other water supply hard pipe 11 by a return hose 13. The other end of the water supply hard pipe 11 is equipped with a rotary joint 14. A water cooling roller 15 is installed between the two rotary joints 14. The height adjustment component is used to adjust the height of the water cooling roller 15.

[0022] After the hot press plate 6 is pushed by the hydraulic cylinder 4 to hot press the particleboard placed on the pallet 2, the hydraulic cylinder 4 pulls the hot press plate 6 to move upward and reset. The height adjustment component adjusts the height of the water-cooled roller 15, so that the water-cooled roller 15 pulled by the traction component can roll back and forth on the top of the hot-pressed particleboard. The water pump 10 drives the water in the first water tank 8, the second water tank 9 and the water-cooled roller 15 to circulate. The cold water flowing through the water-cooled roller 15 cools the particleboard, which greatly improves the cooling efficiency of the particleboard after hot pressing and improves the processing efficiency of the particleboard. It also prevents the pallet 2 from being over-cooled and affecting the subsequent processing of the particleboard.

[0023] The height adjustment component includes a support plate 18, a first water tank 8 and a second water tank 9, both of which are installed at the bottom of the support plate 18. Two electric push rods 19 are installed on the support plate 18. A fixing block 20 is fixedly installed at the output end of the electric push rod 19. The two fixing blocks 20 are respectively fixedly sleeved on the two water supply hard pipes 11.

[0024] The height of the fixed block 20 can be adjusted by using the electric push rod 19, so that the height of the water supply pipe 11 on the fixed block 20 can be adjusted accordingly. In this way, the height of the water cooling roller 15 can be appropriately adjusted according to the thickness of the particleboard after hot pressing, ensuring that the water cooling roller 15 can effectively contact the particleboard after hot pressing, which facilitates the cooling of the particleboard after pressing.

[0025] The bottom of the carrier plate 7 is equipped with four rollers 17, which are located on both sides of the traction assembly. The traction assembly includes a rectangular frame plate 21, which is mounted on the base 1. A lead screw 22 is rotatably connected between the left and right inner walls of the rectangular frame plate 21 through bearings. A drive motor 23 is mounted on the left side of the rectangular frame plate 21, and the lead screw 22 is driven by the drive motor 23. A carrier block 24 is threaded onto the lead screw 22. The carrier plate 7 is fixedly mounted on the top of the carrier block 24, and the carrier block 24 slides against the inner wall of the rectangular frame plate 21.

[0026] The drive motor 23 drives the lead screw 22 to rotate, and the lead screw 22 drives the carrier block 24 to move in the lead screw transmission manner. The carrier block 24 pulls the carrier plate 7 to move, thereby driving the water-cooled roller 15 to move on the top of the formed particleboard. With the help of four rollers 17 to assist the movement of the carrier plate 7, the pressure on the lead screw 22 can be distributed, and the movement of the carrier plate 7 can be made more convenient.

[0027] Working principle of this utility model:

[0028] The hydraulic cylinder 4 is extended, causing it to push the hot press plate 6 downward. The hot press plate 6, together with the support plate 2, can heat-press the particleboard on the support plate 2 into shape. Then, the hydraulic cylinder 4 drives the hot press plate 6 upward, causing it to return to the starting position. The electric push rod 19 is extended, causing it to push the fixing block 20 upward. The fixing block 20 drives the water supply pipe 11 upward, causing the water cooling roller 15 between the two water supply pipes 11 to move upward as well. The extension of the electric push rod 19 is stopped when the vertical height difference between the water cooling roller 15 and the support plate 2 is exactly the same as the thickness of the particleboard after heat pressing.

[0029] Operating the water pump 10 causes the water to circulate between the first water tank 8, the second water tank 9, the water supply hard pipe 11, the water guide hose 12, the return hose 13, the water cooling roller 15, and the connecting pipe. The chiller helps cool the water inside the second water tank 9. The drive motor 23 drives the lead screw 22 to rotate. The lead screw 22 drives the carrier block 24 to move in a lead screw transmission manner. The carrier block 24 finally pulls the water cooling roller 15 to move back and forth on the top of the particleboard. The cold water flowing through the water cooling roller 15 helps the particleboard to quickly complete the cooling process, so that the particleboard can be quickly shaped. After the particleboard is shaped, the worker can remove it. At this time, the pallet 2 still has residual heat, and the worker can use the pallet 2 to continue processing the next particleboard.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
