Description

Technical Field

[0001] This utility model relates to the field of low-temperature resistant sheet processing technology, and in particular to a low-temperature resistant sheet curling and anti-breakage forming processing device. Background Technology

[0002] The demand for low-temperature resistant sheets (such as low-temperature PE and PVC sheets) continues to grow in fields such as cold chain packaging, building pipelines in cold regions, and low-temperature industrial equipment. However, these sheets are prone to problems such as decreased toughness and increased brittleness in low-temperature environments. Therefore, it is necessary to develop a low-temperature resistant sheet curling and anti-breakage molding processing device.

[0003] Low-temperature resistant sheet curling and anti-breakage forming processing equipment can reduce stress concentration and rigid friction of sheets at low temperatures. Ultimately, while ensuring sheet forming accuracy, it significantly reduces the curling breakage rate, improves equipment versatility and production efficiency, and meets the high-quality processing needs of various industries for low-temperature resistant sheets. However, in previous technologies, fixed-specification pressure rollers and curling structures could not adapt to sheets of different thicknesses, and rigid contact at low temperatures easily caused sheet breakage and surface scratches, resulting in poor versatility. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a low-temperature resistant sheet curling and anti-breakage forming processing device, which aims to improve the problems in the existing technology where fixed-specification pressure rollers and curling structures cannot be adapted to sheets of different thicknesses, and rigid contact at low temperatures easily causes sheet breakage and surface scratches, and has poor versatility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature resistant sheet curling and anti-breakage forming processing device, comprising a base plate, a support platform fixedly connected to the upper surface of the base plate, a support plate fixedly connected to the outer wall of the support platform, a cylinder fixedly connected inside the support plate, a sliding frame fixedly connected to the output end of the cylinder, a limit block slidably connected inside the sliding frame, the outer wall of the limit block fixedly connected to the outer wall of the support platform, a connecting shaft fixedly connected to the outer wall of the sliding frame, a rotating frame one and a rotating frame two rotatably connected to the outer wall of the connecting shaft respectively, a rotating shaft rotatably connected inside both rotating frame one and rotating frame two, a moving block rotatably connected to the outer wall of the rotating shaft, a limit strip slidably connected inside the moving block, the outer wall of the limit strip fixedly connected to the outer wall of the support platform, a pressure roller rotatably connected to the outer wall of the rotating shaft, the outer wall of the pressure roller rotatably connected to the outer wall of the moving block, and a pressing assembly provided on the upper surface of the base plate.

[0006] Through the above technical solution: the starting cylinder can push the sliding frame to slide on the outer wall of the limiting block. Then, the movement of the sliding frame can be driven by the connecting shaft to rotate the first and second rotating frames. The rotation of the first and second rotating frames can then drive the two moving blocks to move and clamp each other under the support of the limiting strip through the rotating shaft. This allows the moving blocks and the rotating shaft to drive the two pressure rollers to clamp the sheet. For the shaping requirements of low-temperature resistant sheets, the spacing can be finely adjusted by the movement and clamping of the pressure rollers, which can accurately control the final thickness deviation of the sheet and ensure the flatness of the sheet surface, avoiding local bulges or depressions caused by uneven spacing.

[0007] Preferably, the pressing component includes a support frame, the lower surface of which is fixedly connected to the upper surface of the base plate, a motor is fixedly connected inside the support frame, and a rotating disk is fixedly installed at the output end of the motor.

[0008] Preferably, the inside of the rotating disk is rotatably connected to a drive shaft, and the outer wall of the drive shaft is slidably connected to a sliding block.

[0009] Preferably, a fixed block is slidably connected to the outer wall of the sliding block, and the lower surface of the fixed block is fixedly connected to the upper surface of the base plate.

[0010] Preferably, a spring is fixedly connected to the lower surface of the sliding block, and the lower surface of the spring is fixedly connected to the upper surface of the base plate.

[0011] Preferably, a connecting block is fixedly connected to the upper surface of the sliding block, and a pressing plate is fixedly connected to the upper surface of the connecting block.

[0012] Preferably, a fixing frame and a fixing plate are fixedly connected to the upper surface of the base plate. A rotating shaft is fixedly connected inside the fixing frame and the fixing plate. A guide roller is rotatably connected to the outer wall of the rotating shaft. A pressing plate is fixedly connected to the outer wall of the fixing plate. The pressing plate is located above the pressing plate.

[0013] Preferably, both the first pressing plate and the second pressing plate have an inner layer inside, and the outer wall of the inner layer has an outer layer.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the two pressure rollers can be driven to move relative to each other through the mutual cooperation between the cylinder, sliding frame, limiting block, connecting shaft, rotating frame one, rotating frame two, moving block, rotating shaft, and limiting strip. By driving and adjusting the distance between the two pressure rollers, low-temperature resistant sheets of different thicknesses can be directly matched, avoiding the problem of excessive pressure on thin materials and poor pressing of thick materials due to fixed distance.

[0015] 2. In this utility model, before the sheet enters the lifting and pressing area, the transmission path is optimized by the set guide roller, thereby preventing the sheet from bending when entering the pressing area. Then, through the cooperation between the motor, rotating disk, drive shaft, sliding block, spring, and connecting block, the lifting and pressing structure can adjust the pressing height through precise lifting and lowering. With the silicone pressing plate one and pressing plate two, uniform pressure is applied to the local area, preventing the sheet from creases or cracks due to local stress concentration. In addition, the set spring can make pressing plate two slowly contact the sheet and gradually apply pressure, thereby reducing the instantaneous impact force and reducing the risk of breakage through buffering.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a low-temperature resistant sheet curling and anti-breakage forming processing device, including a base plate 1, a support platform 2 fixedly connected to the upper surface of the base plate 1, a support plate 3 fixedly connected to the outer wall of the support platform 2, a cylinder 4 fixedly connected to the inside of the support plate 3, a sliding frame 5 fixedly connected to the output end of the cylinder 4, a limit block 6 slidably connected inside the sliding frame 5, the outer wall of the limit block 6 fixedly connected to the outer wall of the support platform 2, a connecting shaft 7 fixedly connected to the outer wall of the sliding frame 5, a rotating frame 8 and a rotating frame 9 rotatably connected to the outer wall of the connecting shaft 7 respectively, a rotating shaft 29 rotatably connected inside the rotating frame 8 and the rotating frame 9, a moving block 10 rotatably connected to the outer wall of the rotating shaft 29, a limit strip 12 slidably connected inside the moving block 10, the outer wall of the limit strip 12 fixedly connected to the outer wall of the support platform 2, a pressure roller 11 rotatably connected to the outer wall of the rotating shaft 29, the outer wall of the pressure roller 11 rotatably connected to the outer wall of the moving block 10, and a pressing assembly provided on the upper surface of the base plate 1; Specifically, the base plate 1 fixes the support platform 2, the support platform 2 fixes the position of the support plate 3, the support plate 3 fixes the position of the cylinder 4, the cylinder 4 pushes the sliding frame 5 to slide on the outer wall of the limiting block 6, the limiting block 6 limits the sliding of the sliding frame 5, the sliding of the sliding frame 5 drives the connecting shaft 7 to move, the movement of the sliding frame 5 drives the rotating frame 8 and the rotating frame 9 to rotate through the connecting shaft 7, and the rotation of the rotating frame 8 and the rotating frame 9 drives the moving block 10 to slide through the rotating shaft 29. At the same time, the limiting strip 12 supports the moving block 10 to limit its movement, and the rotating shaft 29 supports the position of the pressure roller 11. Example 1:

[0020] Reference Figure 1 and Figure 5 The pressing component includes a support frame 20, the lower surface of which is fixedly connected to the upper surface of the base plate 1, and a motor 21 is fixedly connected inside the support frame 20. A rotating disk 22 is fixedly installed at the output end of the motor 21. Specifically, the base plate 1 serves to fix the position of the support frame 20, the support frame 20 serves to fix the position of the motor 21, and the motor 21 drives the rotating disk 22 to rotate synchronously.

[0021] Reference Figure 2 and Figure 5 The rotating disk 22 is rotatably connected to a drive shaft 23, and a sliding block 24 is slidably connected to the outer wall of the drive shaft 23; a fixed block 19 is slidably connected to the outer wall of the sliding block 24, and the lower surface of the fixed block 19 is fixedly connected to the upper surface of the base plate 1; a spring 25 is fixedly connected to the lower surface of the sliding block 24, and the lower surface of the spring 25 is fixedly connected to the upper surface of the base plate 1; a connecting block 26 is fixedly connected to the upper surface of the sliding block 24, and a pressing plate 18 is fixedly connected to the upper surface of the connecting block 26; a fixing frame 13 and a fixing plate 16 are fixedly connected to the upper surface of the base plate 1, and a rotating shaft 14 is fixedly connected inside both the fixing frame 13 and the fixing plate 16; a guide roller 15 is rotatably connected to the outer wall of the rotating shaft 14; a pressing plate 17 is fixedly connected to the outer wall of the fixing plate 16, and the pressing plate 17 is located above the pressing plate 18. Specifically, the rotation of the rotating disk 22 drives the drive shaft 23 to rotate synchronously. The drive shaft 23 then rotates within the sliding groove of the sliding block 24, causing the sliding block 24 to move vertically. Simultaneously, the fixed block 19 supports the movement of the sliding block 24, and the spring 25 supports and buffers the sliding block 24's vertical movement. The base plate 1 fixes the fixed block 19 and the spring 25 in their positions, and the sliding block 24 fixes the connecting block 26 in its position. When the sliding block 24 moves, the connecting block 26 drives the pressing plate 18 to move synchronously up and down. The base plate 1 also fixes the position of the fixing frame 13, which in turn fixes the position of the rotating shaft 14. The rotating shaft 14 supports the rotation of the guide roller 15. Example 2:

[0022] Reference Figure 2 and Figure 6 Both the pressing plate 17 and the pressing plate 28 have an inner layer 27 inside, and the outer wall of the inner layer 27 has an outer layer 28. Specifically, the inner layer 27 of both the first pressing plate 17 and the second pressing plate 18 is made of highly elastic silicone material, which can directly contact the sheet. The elastic deformation of the silicone disperses the pressing pressure, avoiding the sheet from cracking due to local high pressure points. At the same time, the silicone surface has a moderate coefficient of friction, which can prevent the sheet from slipping and shifting during pressing, ensuring positioning accuracy. The outer layer 28 is made of lightweight aluminum alloy material, which can serve as a support layer to ensure the overall flatness of the pressing plate, avoid uneven pressure distribution due to plate deformation during pressing, and reduce the load on lifting and improving the lifting response speed.

[0023] Working principle: In use, the cylinder 4 is first started to drive the sliding frame 5 to move under the limit of the limiting block 6. Then, the movement of the sliding frame 5 can drive the rotating frame 8 and the rotating frame 9 to rotate through the connecting shaft 7. The rotation of the rotating frame 8 and the rotating frame 9 can drive the moving block 10 to slide on the outer wall of the limiting strip 12 through the rotating shaft 29. Then, the movement of the two moving blocks 10 can drive the two pressure rollers 11 to move and clamp each other. At the same time, the rotating shaft 29 can drive the two pressure rollers 11 to rotate. By adjusting the distance between the two pressure rollers 11, the pressing pressure distribution of the wide sheet can be optimized to prevent the edges from crease due to excessive pressure and the middle from failing to set due to insufficient pressure. Before the sheet enters the lifting and pressing area, the multiple guide rollers 15 optimize the transmission path and prevent the sheet from bending into the pressing area. When the position of the second pressing plate 18 needs to be adjusted, the starter motor 21 can be driven by the rotating disk 22 to rotate. The drive shaft 23 slides in the sliding groove of the sliding block 24, which can drive the sliding block 24 to move under the support of the fixed block 19. At the same time, when the sliding block 24 moves up and down, the spring 25 provides support and buffer. Thus, the movement of the sliding block 24 can drive the second pressing plate 18 to move vertically up and down through the connecting block 26. When processing low-temperature resistant sheets of different thicknesses, the distance between the second pressing plate 18 and the first pressing plate 17 can be adjusted in real time. When processing thick sheets, the position of the second pressing plate 18 is lowered to avoid excessive compression. When processing thin sheets, the position of the second pressing plate 18 is raised to ensure the pressing force and prevent the problem of thick sheets being damaged and thin sheets not being pressed firmly due to the fixed distance.

[0024] 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.
