Description

Technical Field

[0001] This utility model relates to the technical field of rubber pressing, and in particular to a rubber calendering device with adjustable thickness. Background Technology

[0002] A calender is a machine that uses two or more rollers arranged in a specific pattern to press and stretch rubber or plastic into sheets of a certain thickness and surface shape at a specific temperature. It can also be used to coat fiber cord fabric or steel wire cord fabric with adhesive. Existing technology publication number CN222768846U discloses a rubber calendering device, including: a frame, calendering rollers, cooling rollers, and a thickness monitoring component. The calendering rollers are horizontally arranged on the frame. A cooling roller is horizontally arranged on one side of the calendering rollers and mounted on the frame. The calendered rubber material is cooled by the cooling roller. A thickness monitoring component is horizontally arranged on the other side of the cooling roller. However, existing calenders cannot easily adjust the thickness of the calendered product; adjusting the thickness of the calendered rubber product is cumbersome and increases the physical exertion of the workers. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a thickness-adjustable rubber calendering device that can adjust the thickness of calendered products, is easy to operate, expands the application range of the device, and can meet the production needs of calendered products of different thicknesses.

[0004] This utility model discloses a rubber calendering device with adjustable thickness, comprising a base, two vertical plates, a lower pressure roller, an upper pressure roller, an adjusting component, a feeding component, and a second adjusting component. Vertical plates are installed at the front and rear ends of the top of the base, and the lower pressure roller is rotatably mounted between the two vertical plates. The feeding component is installed on the left side wall of the vertical plate. The adjusting component is installed on the top of the base, and the upper pressure roller is mounted on the adjusting component, positioned above the lower pressure roller. The second adjusting component is installed on the right side wall of the vertical plate. The distance between the upper and lower pressure rollers can be adjusted using the adjusting component, thereby adjusting the thickness of the calendered product. This design is convenient to operate, expands the device's application range, and can meet the production needs of calendered products of different thicknesses. The feeding component guides and limits the rubber sheet, ensuring it is positioned in the middle of the lower pressure roller, thus guaranteeing processing quality.

[0005] Preferably, the adjusting components include a fixed frame, two threaded rods, two gearboxes, a dual-output motor, two lifting blocks, an adjusting plate, and two adjusting rods. The bottom front and rear ends of the fixed frame are mounted on the top front and rear ends of the base. Adjusting slots are provided at the top front and rear ends of the fixed frame. The threaded rods are rotatably installed in the adjusting slots, and the input end of the threaded rods is connected to the output end of the gearboxes. The dual-output motors are mounted on the top of the fixed frame, and the output ends on both sides of the dual-output motors are connected to the input end of the gearboxes. The lifting blocks are slidably installed in the adjusting slots and screwed onto the outer wall of the threaded rods. An adjusting plate is installed between the two lifting blocks, and adjusting rods are installed at the bottom front and rear ends of the adjusting plate. The upper pressure roller is installed between the lower parts of the two adjusting rods. An insertion slot matching the upper pressure roller is provided at the top of the upright plate. Starting the dual-output motors drives the threaded rods to rotate through the gearboxes, causing the lifting blocks to move within the adjusting slots. The distance between the upper and lower pressure rollers is adjusted by the adjusting plate and adjusting rods, thereby adjusting the thickness of the calendered product. The operation is convenient, expands the application range of the device, and can meet the production needs of calendered products of different thicknesses.

[0006] Preferably, it also includes an upper cooling roller, two extension blocks and a lower cooling roller. An extension block is installed on the lower side of the right side wall of the vertical plate, and a lower cooling roller is rotatably installed between the two extension blocks. The upper cooling roller is installed above the lower cooling roller through a second adjusting component. The rubber material is first calendered by the lower pressure roller and the upper pressure roller. Then, the calendered rubber sheet enters between the upper cooling roller and the lower cooling roller to cool the rubber sheet, stabilize the rubber sheet and prevent deformation during subsequent processing or use.

[0007] Preferably, the second adjusting component includes a fixed plate, an adjusting screw, a mounting plate, two connecting blocks, and a guide assembly. The fixed plate is installed on the top right side of the two upright plates. Diagonal braces are provided between the front and rear ends of the bottom of the fixed plate and the right side wall of the upright plate. The adjusting screw is screwed into the middle of the fixed plate. The mounting plate is rotatably installed on the bottom of the adjusting screw. Connecting blocks are installed on the front and rear ends of the bottom of the mounting plate. The upper cooling roller is rotatably installed between the two connecting blocks. Rotating the adjusting screw pushes the mounting plate downward, and the upper cooling roller is moved through the connecting blocks to adjust the distance between it and the lower cooling roller, thereby meeting the production needs of rolled products of different thicknesses and improving practicality.

[0008] Preferably, the guide assembly includes a connecting plate, two guide slide rods, and two guide sliders. The middle of the connecting plate is rotatably connected to the upper end of the adjusting screw. Guide slide rods are installed at the front and rear ends of the bottom of the connecting plate. The guide slide rods are slidably mounted on the fixed plate, and the bottom of the guide slide rods is connected to the top of the mounting plate. A guide groove is provided on the right side wall of the vertical plate, and guide sliders are installed at the front and rear ends of the left side wall of the mounting plate. The guide sliders are slidably mounted in the guide groove. When the mounting plate moves, it drives the guide slide rods to slide on the fixed plate, guiding them. At the same time, the connecting plate increases the connection strength between the guide slide rod and the adjusting screw, ensuring stability. Meanwhile, when the mounting plate moves, it drives the guide sliders to slide in the guide groove, further guiding and limiting them, ensuring stability during movement and improving machining accuracy.

[0009] Preferably, the feeding component includes two support rods, a feeding guide plate, a rotating rod, two moving blocks, and two guide plates. The two support rods are respectively installed on the left side walls of the two vertical plates. The feeding guide plate is installed at the top of the support rods. Fixed plates are provided at the front and rear ends of the bottom left side of the feeding guide plate. A rotating rod is rotatably installed between the two fixed plates. Threaded grooves are symmetrically opened at the front and rear ends of the rotating rod. The moving blocks are screwed onto the outer wall of the rotating rod. A guide plate is installed on the top of the moving blocks. The guide plate is slidably installed on the top of the feeding guide plate. The feeding guide plate guides the rubber sheet to enter between the lower pressure roller and the upper pressure roller. Rotating the rotating rod adjusts the distance between the two moving blocks, allowing the guide plate to move on the top of the feeding guide plate. This can limit and guide the rubber sheet, ensuring that it is located in the middle position of the lower pressure roller and ensuring processing quality.

[0010] Preferably, it also includes a limiting frame, with the top of the feed guide plate installed at both the front and rear ends of the bottom of the limiting frame, and the top of the guide plate slidably installed at the bottom of the limiting frame; when the moving block drives the guide plate, the top of the guide plate slides at the bottom of the limiting frame to limit and guide it, ensuring stability.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the distance between the upper and lower pressure rollers can be adjusted by adjusting the components, thereby adjusting the thickness of the calendered product. The operation is more convenient, the application range of the device is expanded, and it can meet the production needs of calendered products of different thicknesses. The feeding component can guide and limit the film to ensure that it is located in the middle position of the lower pressure roller, thus ensuring the processing quality. Attached Figure Description

[0014] like Figures 1 to 5As shown, upright plates 2 are installed at the front and rear ends of the top of the base 1, and a lower pressure roller 3 is rotatably installed between the two upright plates 2. The bottom front and rear ends of the fixed frame 4 are installed at the front and rear ends of the top of the base 1. Adjustment grooves are opened at the front and rear ends of the upper part of the fixed frame 4. The threaded rod 5 is rotatably installed in the adjustment groove. The input end of the threaded rod 5 is connected to the output end of the gearbox 6. The dual output motor 7 is installed at the top of the fixed frame 4. The output ends of the dual output motor 7 on both the front and rear sides are connected to the input end of the gearbox 6. The lifting block 8 is slidably installed in the adjustment groove. The lifting block 8 is screwed onto the outer wall of the threaded rod 5. An adjusting plate 9 is installed between the lowering blocks 8. Adjusting rods 10 are installed at the front and rear ends of the bottom of the adjusting plate 9. An upper pressure roller 11 is installed between the lower parts of the two adjusting rods 10. The top of the vertical plate 2 has an insertion groove that matches the upper pressure roller 11. An extension block 20 is installed on the lower side of the right side wall of the vertical plate 2. A lower cooling roller 21 is rotatably installed between the two extension blocks 20. A fixing plate 12 is installed at the top right side of the two vertical plates 2. Diagonal bracing rods are provided between the front and rear ends of the bottom of the fixing plate 12 and the right side wall of the vertical plate 2. An adjusting screw 13 is screwed into the middle of the fixing plate 12. The bottom of the adjusting screw 13 rotates... A mounting plate 15 is mounted on the fixed plate 12. Connecting blocks 18 are mounted at the front and rear ends of the bottom of the mounting plate 15. An upper cooling roller 19 is rotatably mounted between the two connecting blocks 18. The middle part of the connecting plate 14 is rotatably connected to the upper end of the adjusting screw 13. Guide slide rods 16 are mounted at the front and rear ends of the bottom of the connecting plate 14. The guide slide rods 16 are slidably mounted on the fixed plate 12. The bottom of the guide slide rods 16 is connected to the top of the mounting plate 15. A guide groove is opened on the right side wall of the vertical plate 2. Guide sliders 17 are mounted at the front and rear ends of the left side wall of the mounting plate 15. The guide sliders 17 are slidably mounted in the guide groove. Each support rod 22 is installed on the left side wall of the two upright plates 2. The feed guide plate 23 is installed on the top of the support rod 22. The front and rear ends of the bottom left side of the feed guide plate 23 are provided with fixed plates. A rotating rod 24 is rotatably installed between the two fixed plates. The front and rear ends of the rotating rod 24 are symmetrically provided with threaded grooves. The moving block 25 is screwed onto the outer wall of the rotating rod 24. The top of the moving block 25 is provided with a guide plate 26. The guide plate 26 is slidably installed on the top of the feed guide plate 23. The top of the feed guide plate 23 is installed on the front and rear ends of the bottom of the limiting frame 27. The top of the guide plate 26 is slidably installed on the bottom of the limiting frame 27. The rubber sheet is guided by the feed guide plate 23, allowing it to enter between the lower pressure roller 3 and the upper pressure roller 11. Rotating the rotating rod 24 adjusts the distance between the two moving blocks 25, causing the guide plate 26 to move at the top of the feed guide plate 23. This provides limiting guidance for the rubber sheet, ensuring it is positioned in the middle of the lower pressure roller 3 and guaranteeing processing quality. When the moving block 25 moves the guide plate 26, the top of the guide plate 26 slides at the bottom of the limiting frame 27, providing limiting guidance and ensuring stability. Starting the dual-output motor 7 drives the threaded rod 5 through the gearbox 6, causing the lifting block 8 to move within the adjusting groove. The distance between the upper pressure roller 11 and the lower pressure roller 3 is adjusted by the adjusting plate 9 and the adjusting rod 10, thereby adjusting the thickness of the calendered product. The operation is convenient, expanding the application range of the device and meeting the production needs of calendered products of different thicknesses. First, the film undergoes calendering through the lower pressure roller 3 and the upper pressure roller 11. Then, the calendered film enters between the upper cooling roller 19 and the lower cooling roller 21 for cooling treatment, stabilizing the film and preventing deformation during subsequent processing or use. Rotating the adjusting screw 13 pushes the mounting plate 15 downward, which in turn moves the upper cooling roller 19 through the connecting block 18 to adjust the distance between it and the lower cooling roller 21, meeting the production needs of calendered products of different thicknesses and improving practicality. When the mounting plate 15 moves, it drives the guide slide rod 16 to slide on the fixed plate 12 for guidance. At the same time, the connecting plate 14 increases the connection strength between the guide plate 15 and the adjusting screw 13, ensuring stability. Simultaneously, when the mounting plate 15 moves, it drives the guide slider 17 to slide in the guide groove for further guidance and limitation, ensuring stability during movement and improving processing accuracy.

[0015] like Figures 1 to 5As shown, this utility model discloses a rubber calendering device with adjustable thickness. During operation, the dual-output motor 7 drives the threaded rod 5 to rotate via the gearbox 6, causing the lifting block 8 to move within the adjustment groove. The distance between the upper pressure roller 11 and the lower pressure roller 3 is adjusted via the adjusting plate 9 and the adjusting rod 10, thereby adjusting the thickness of the calendered product. The operation is relatively convenient. The rubber material first undergoes calendering processing through the lower pressure roller 3 and the upper pressure roller 11. Subsequently, the calendered rubber sheet enters between the upper cooling roller 19 and the lower cooling roller 21 for cooling treatment, stabilizing the rubber sheet and preventing deformation during subsequent processing or use. Rotating the adjusting screw 13 pushes the mounting plate 15 downwards, driving the upper cooling roller through the connecting block 18. The distance between the moving adjustment and the lower cooling roller 21 is adjusted to meet the production needs of calendered products of different thicknesses. When the mounting plate 15 moves, it drives the guide slide rod 16 to slide on the fixed plate 12 to guide it. At the same time, the connecting plate 14 can increase the connection strength between the mounting plate 15 and the adjusting screw 13 to ensure stability. When the mounting plate 15 moves, it drives the guide slider 17 to slide in the guide groove to further guide and limit it. The feed guide plate 23 guides the rubber sheet to enter between the lower pressure roller 3 and the upper pressure roller 11. The rotating rod 24 adjusts the distance between the two moving blocks 25, so that the guide plate 26 moves on the top of the feed guide plate 23 to limit and guide the rubber sheet to ensure that it is located in the middle position of the lower pressure roller 3.
