Description

Technical Field

[0001] This application relates to the technical field of foamed board production, and in particular to a multi-dimensional adjustable shaping and pressing device for a foamed board production line. Background Technology

[0002] In the industrial production of foamed boards made from polymer materials such as PP (polypropylene), multi-hole die extrusion is one of the mainstream molding technologies. The core process involves extruding multiple independent polymer strips with a specific foaming ratio simultaneously into the production line through a dedicated multi-hole die. These strips, freshly extruded from the die in a high-temperature, semi-molten state, possess strong self-adhesion and naturally bond together during subsequent transport, ultimately forming a continuous foamed board with a preset thickness. This process, due to its ability to achieve continuous production and high efficiency, is widely used in the manufacture of foamed boards for building insulation, packaging cushioning, and other applications.

[0003] However, the production method that relies on the self-adhesion of the material strips is affected by factors such as the temperature control accuracy of each flow channel of the extrusion equipment, the uniformity of material melting, and the wear of the die outlet. It is difficult to achieve complete uniformity in the extrusion speed, surface temperature, and foaming degree of each material strip, resulting in differences in contact pressure and bonding time between material strips. This leads to uneven bonding strength inside the finished board, and some areas are prone to weak bonding, internal gaps, or even holes, which seriously affects the structural strength and thermal insulation performance of the board. Utility Model Content

[0004] The purpose of this application is to provide a multi-dimensional adjustable shaping and pressing device for foamed board production lines, which solves the problem that production methods that rely on the adhesiveness of the boards themselves are subject to various factors, resulting in uneven internal bonding strength of the finished boards, weak bonding in some areas, internal gaps or even holes, which affect the structural strength and thermal insulation performance of the boards.

[0005] This application provides a multi-dimensional adjustable shaping and pressing device for a foamed board production line, which adopts the following technical solution: It includes a frame, inside which are two lower fixed plates and two upper fixed plates. Several lower pressure rollers are rotatably connected between the two lower fixed plates, and several upper pressure rollers are rotatably connected between the two upper fixed plates. A support plate is fixedly connected to the upper surface of each upper fixed plate. Several upper positioning plates are fixedly connected inside the frame. A hydraulic rod is fixedly connected to the lower surface of each upper positioning plate. The output shaft of the hydraulic rod is fixedly connected to a lower positioning plate. Two support plates are fixedly connected to both ends of each lower positioning plate. Side plates are provided on the sides of each support plate. Several side pressure rollers are rotatably connected to the lower surface of each side plate. A bidirectional lead screw is rotatably connected between the two support plates. Moving blocks are threaded to the outer sides of both ends of the bidirectional lead screw. Two moving blocks are fixedly connected to two side plates respectively. By adopting the above technical solution, when the device is in use, the lower positioning plate can be driven to descend by the hydraulic rod, which in turn causes the upper fixed plate to drive the upper pressure roller to descend. After the upper pressure roller descends, it can press the plate through the lower pressure roller. At the same time, the bidirectional screw can cause the moving block to move the side plate. After the side plate moves, several side pressure rollers can press the two sides of the plate, thereby squeezing the plate in four directions (up, down, left, and right), so that the materials inside the plate are firmly bonded together. This solves the problem that production methods that rely on the adhesiveness of the plate itself are affected by various factors, which can lead to uneven bonding strength inside the finished plate, and some areas are prone to poor bonding, internal gaps or even holes, affecting the structural strength and thermal insulation performance of the plate.

[0006] Preferably, a plurality of lower fixing blocks are fixedly connected to one side surface of the lower fixing plate, and the lower fixing blocks are fixedly connected to the frame; a plurality of upper fixing blocks are fixedly connected to one side surface of the upper fixing plate; a slide rail is slidably connected to the side surface of the upper fixing blocks away from the upper fixing plate, and the slide rail is fixedly connected to the frame. By adopting the above technical solution, the lower fixing block ensures that the lower fixing plate is stably connected to the frame, preventing the lower pressure roller from shifting during operation; the upper fixing block slides with the slide rail to provide guidance for the lifting and lowering of the upper fixing plate, ensuring accurate positioning of the upper pressure roller during adjustment and improving the stability of the device operation.

[0007] Preferably, a plurality of first transmission belts are provided on the side of one of the lower fixed plates and the side of one of the upper fixed plates. The first transmission belts are internally connected to two first synchronous pulleys. The plurality of first synchronous pulleys are respectively fixedly connected to a plurality of lower pressure rollers and a plurality of upper pressure rollers. A second transmission belt is provided between two adjacent first transmission belts. The second transmission belts are internally connected to two second synchronous pulleys. The plurality of second synchronous pulleys are respectively fixedly connected to a plurality of first synchronous pulleys. By adopting the above technical solution, the first transmission belt cooperates with the first synchronous pulley to realize the synchronous rotation of several lower pressure rollers and several upper pressure rollers, ensuring that the conveying speed of the plate is uniform and avoiding damage to the surface of the plate due to the difference in the rotation speed of the rollers.

[0008] Preferably, a first mounting plate is fixedly connected to the side of one of the lower fixing plates, a first motor is fixedly connected to the side of the first mounting plate, and the output shaft of the first motor passes through the first mounting plate and the lower fixing plate and is fixedly connected to one of the lower pressure rollers; a second mounting plate is fixedly connected to the side of one of the upper fixing plates, a second motor is fixedly connected to the side of the second mounting plate, and the output shaft of the second motor passes through the second mounting plate and the upper fixing plate and is fixedly connected to one of the upper pressure rollers. By adopting the above technical solution, the first motor and the second motor provide independent power to the lower pressure roller and the upper pressure roller, respectively, and are securely installed through the first mounting plate and the second mounting plate, which makes it easy to adjust the roller speed according to production needs and adapt to process scenarios with different extrusion speeds.

[0009] Preferably, the surfaces of the side pressure roller, the lower pressure roller, and the upper pressure roller are all coated with a Teflon coating; By adopting the above technical solutions, the Teflon coating on the surface of the side pressure roller, lower pressure roller and upper pressure roller can effectively prevent high-temperature plates from sticking to the roller body, ensure that the plate surface is smooth and undamaged, and at the same time reduce the frequency of roller cleaning and improve production continuity.

[0010] Preferably, a plurality of sliding rods are fixedly connected between the two support plates, and two sliders are slidably connected to the outer side of the sliding rods, with the two sliders respectively fixedly connected to the two side plates; By adopting the above technical solution, the slide bar and the slider work together to provide guidance for the movement of the side plate, avoid the side plate from shifting when it rotates with the bidirectional screw, ensure that the pressure of the side pressure roller on both sides of the plate is uniform, and improve the shaping effect.

[0011] Preferably, a third mounting plate is fixedly connected to the upper surface of one of the support plates, and a third motor is fixedly connected to the upper surface of the third mounting plate; By adopting the above technical solution, the third mounting plate provides a stable mounting carrier for the third motor.

[0012] Preferably, the output shaft of the third motor is fixedly connected to a first gear, and a second gear is fixedly connected to the surface of one of the support plates. The second gear is fixedly connected to a bidirectional lead screw, and the second gear meshes with the first gear. By adopting the above technical solution, the first gear meshes with the second gear to transmit power from the third motor to the bidirectional lead screw, thereby achieving smooth rotation of the bidirectional lead screw.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. This multi-dimensional adjustable shaping and pressing device for a foamed board production line comprises a lower pressure roller, an upper pressure roller, a first synchronous pulley, a second synchronous pulley, a first motor, a second motor, a hydraulic rod, side plates, side pressure rollers, a bidirectional screw, and a third motor. During operation, the hydraulic rod drives the lower positioning plate to descend, which in turn causes the upper fixed plate to move the upper pressure roller. After the upper pressure roller descends, the lower pressure roller presses the board. The third motor, through the first and second gears, rotates the bidirectional screw, causing the moving block to move the side plates. After the side plates move, several side pressure rollers press the sides of the board, thus squeezing the board in four directions (up, down, left, and right), firmly binding the internal materials of the board together. The bonding method solves the problem that production methods relying on the adhesive properties of the boards themselves are susceptible to uneven bonding strength within the finished boards due to various factors. This can lead to weak bonding, internal gaps, or even holes in some areas, affecting the structural strength and thermal insulation performance of the boards. Simultaneously, the hydraulic rod and the third motor can adjust the distance between the upper and lower pressure rollers, as well as the distance between several side pressure rollers. The first and second motors can drive the lower and upper pressure rollers to rotate via the first and second synchronous pulleys. This not only allows the device to flexibly adapt to the production of boards of different thicknesses and widths for extrusion and shaping, but also to process scenarios with different extrusion speeds for traction and conveying of the boards, improving the device's versatility and production line integration.

Several lower fixed blocks 6 are fixedly connected to one side surface of the lower fixed plate 2. The lower fixed blocks 6 are fixedly connected to the frame 1. Several upper fixed blocks 7 are fixedly connected to one side surface of the upper fixed plate 4. The side surface of the upper fixed block 7 away from the upper fixed plate 4 is slidably connected to a slide rail 8. The slide rail 8 is fixedly connected to the frame 1. Several first transmission belts 9 are provided on the side of one of the lower fixed plates 2 and the side of one of the upper fixed plates 4. The first transmission belts 9 are internally connected to two first synchronous pulleys 10. Several first synchronous pulleys 10 are respectively fixedly connected to several lower pressure rollers 3 and several... A second transmission belt 11 is provided between two adjacent first transmission belts 9, and two second synchronous pulleys 12 are internally connected to the second transmission belt 11. Several second synchronous pulleys 12 are respectively fixedly connected to several first synchronous pulleys 10. A first mounting plate 13 is fixedly connected to the side of one of the lower fixed plates 2, and a first motor 14 is fixedly connected to the side of the first mounting plate 13. The output shaft of the first motor 14 passes through the first mounting plate 13 and the lower fixed plate 2 and is fixedly connected to one of the lower pressure rollers 3. A second mounting plate 15 is fixedly connected to the side of one of the upper fixed plates 4, and a second motor 16 is fixedly connected to the side of the second mounting plate 15. The output shaft of the second motor 16 passes through the second mounting plate 15. The upper fixed plate 4 is fixedly connected to one of the upper pressure rollers 5. The surfaces of the side pressure rollers 22, lower pressure rollers 3, and upper pressure rollers 5 are all coated with Teflon. Several sliding rods 23 are fixedly connected between the two support plates 17. Two sliders 24 are slidably connected to the outer side of the sliding rods 23. The two sliders 24 are fixedly connected to the two side plates 21 respectively. A third mounting plate 27 is fixedly connected to the upper surface of one of the support plates 17. A third motor 28 is fixedly connected to the upper surface of the third mounting plate 27. A first gear 29 is fixedly connected to the output shaft of the third motor 28. A second gear 30 is fixedly connected to the surface of one of the support plates 17. The second gear 30 is fixedly connected to a bidirectional lead screw 25 and meshes with the first gear 29.By configuring the lower pressure roller 3, upper pressure roller 5, first synchronous pulley 10, second synchronous pulley 12, first motor 14, second motor 16, hydraulic rod 19, side plate 21, side pressure roller 22, bidirectional lead screw 25, and third motor 28, the device can be used such that, during operation, the lower positioning plate 20 is driven to descend by the hydraulic rod 19, thereby causing the upper fixed plate 4 to drive the upper pressure roller 5 to descend. After the upper pressure roller 5 descends, it can press the plate material through the lower pressure roller 3. The third motor 28 can rotate the bidirectional lead screw 25 through the first gear 29 and the second gear 30, thereby causing the moving block 26 to drive the side plate 21 to move. After the side plate 21 moves, several side pressure rollers 22 can press the sides of the plate material, thereby squeezing the plate material in four directions (up, down, left, and right), making the material inside the plate material firmly bond together. This invention addresses the problem of uneven bonding strength within the finished sheet material, which is often caused by factors affecting the adhesive properties of the sheet itself. This leads to weak bonding, internal gaps, and even holes in some areas, impacting the structural strength and insulation performance of the sheet. Furthermore, the hydraulic rod 19 and the third motor 28 can adjust the distance between the upper and lower pressure rollers 5 and 3, as well as the distance between several side pressure rollers 22. The first motor 14 and the second motor 16 can drive the lower and upper pressure rollers 3 and 5 to rotate via the first and second synchronous pulleys 10 and 12, respectively. This allows the device to flexibly adapt to the production of sheets of different thicknesses and widths for extrusion and shaping, and can also accommodate different extrusion speeds for traction and conveying of the sheets, improving the device's versatility and production line integration.

[0018] The implementation principle of this application embodiment is as follows: In use, the board is positioned above the lower pressure roller 3. Then, according to the thickness specifications of the foamed board to be processed, the hydraulic rod 19 is activated. The output shaft of the hydraulic rod 19 drives the lower positioning plate 20 to rise and fall. The lower positioning plate 20 drives the upper fixed plate 4 through the support plates 17 fixed at both ends, so that the upper fixed plate 4 rises and falls synchronously along the slide rail 8, thereby adjusting the distance between the upper pressure roller 5 and the lower pressure roller 3, so that the two are adapted to the thickness of the board and form stable pressure on the upper and lower surfaces of the board. Then, according to the width specifications of the board, the third motor 28 is activated. The output shaft of the third motor 28 drives the first gear 29 to rotate. After the first gear 29 rotates, the second gear 30 rotates. After the second gear 30 rotates, the bidirectional lead screw 25 rotates. When the bidirectional lead screw 25 rotates, the moving blocks 26 at both ends of it begin to move. When the moving blocks 26 move, they drive the side plate 21 to move synchronously, thereby adjusting the distance of the side pressure rollers 22 rotatably connected below the side plate 21, so that the side pressure rollers 22 apply uniform pressure to both sides of the board, thereby processing the board. In the extrusion and shaping process, when the sheet material needs to be conveyed, the first motor 14 is started. The output shaft of the first motor 14 drives one of the lower pressure rollers 3 to rotate. After the lower pressure roller 3 rotates, it drives the second synchronous pulley 12 of one of the first synchronous pulleys 10 and one of the first transmission belts 9 to rotate. After the second synchronous pulley 12 rotates, it drives the remaining first synchronous pulleys 10 to rotate through the second transmission belt 11, realizing the synchronous rotation of all the lower pressure rollers 3. At the same time, the second motor 16 is started, and through the above method, it drives several upper pressure rollers 5 to rotate synchronously, providing stable power for conveying the foamed sheet material. During this process, the Teflon coating on the surface of the side pressure rollers 22, lower pressure rollers 3, and upper pressure rollers 5 can effectively prevent the foamed sheet material from sticking to the roller surface under high temperature, ensuring the surface quality of the sheet material and the continuity of production. Finally, through the four-way synchronous extrusion of the upper pressure rollers 5, lower pressure rollers 3, and side pressure rollers 22, combined with the synchronous conveying of the upper pressure rollers 5 and lower pressure rollers 3, the dual functions of shaping and pressing and stable conveying of the foamed sheet material are realized.
