Description

Technical Field

[0001] This utility model relates to the technical field of UV-resistant and heat-resistant PVC roll flattening device, and in particular to a flattening device for processing UV-resistant and heat-resistant PVC rolls. Background Technology

[0002] UV-resistant heat-resistant PVC rolls are a type of PVC roll with good heat resistance. They need to undergo heat treatment during production. Because the rolls still have residual heat after heat treatment, they are prone to shrinking after the rolls have completely cooled down.

[0003] In the prior art, flattening devices are often used to improve the flatness of PVC rolls in order to address the issue of easy shrinkage. Therefore, how to further improve the flattening effect of the flattening device is a problem that should be solved by those skilled in the art. Utility Model Content

[0004] Therefore, it is necessary to provide a flattening device for processing UV-resistant and heat-resistant PVC rolls to address the aforementioned technical problem of how to improve the flattening effect of the flattening device.

[0005] To achieve the above objectives, this utility model provides a flattening device for processing UV-resistant and heat-resistant PVC rolls, comprising a frame, a conveyor mounted on the frame, a belt mounted on the conveyor, a lower shaft rotatably mounted on the frame, the lower shaft being located below and abutting against the belt, a movable frame slidably engaged on the frame, an upper shaft rotatably mounted on the movable frame, the upper shaft being located above the belt, a cooling shaft rotatably mounted on the movable frame, a cooling water bag mounted on the cooling shaft, the cooling water bag abutting against the upper shaft; a transverse block slidably mounted on the frame, the transverse block being slidably engaged with the movable frame, and a correction shaft rotatably mounted on the transverse block.

[0006] Preferably, a linear actuator is mounted on the frame, and the output end of the linear actuator abuts against the moving frame.

[0007] Preferably, a first gear is mounted on the upper shaft, and a second gear is mounted on the cooling shaft, with the first gear and the second gear meshing together.

[0008] Preferably, the movable frame is equipped with a locking block, and the transverse block is provided with a locking groove, and the locking block is slidably locked in the locking groove.

[0009] Preferably, an L-shaped extension frame is installed on the transverse block, and the correction shaft is rotatably installed on the L-shaped extension frame, with the outer ring of the correction shaft extending out of the L-shaped extension frame.

[0010] Preferably, the cooling water bag is equipped with a water exchange nozzle.

[0011] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0012] 1. By combining the conveyor with the cooling water bag, the temperature of the upper and lower shafts is kept low, thus preventing the PVC roll from remaining at a high temperature after being flattened and shrinking only after flattening, thereby improving the flattening effect.

[0013] 2. By coordinating the moving frame and the transverse block, when the moving frame drives the upper shaft to press down, the PVC roll is subjected to greater pressure and its width increases. The correction shaft can automatically move in coordination, making it less likely for the PVC roll to shift when flattened, thereby improving the flattening effect. Attached Figure Description

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Please see Figures 1 to 3This application provides a flattening device for processing UV-resistant and heat-resistant PVC rolls, including a frame 1, a conveyor 2 mounted on the frame 1, the conveyor 2 being a belt conveyor with a built-in servo motor in the prior art, the servo motor speed being customizable to match the flattening operation, a belt 3 mounted on the conveyor 2, the belt 3 being a belt with good thermal conductivity such as a silicone belt or PTFE belt, a lower shaft 4 rotatably mounted on the frame 1, the lower shaft 4 being located below the belt 3 and abutting against the belt 3, a movable frame 5 slidably engaged on the frame 1, an upper shaft 6 rotatably mounted on the movable frame 5, the upper shaft 6 being located above the belt 3, a cooling shaft 7 rotatably mounted on the movable frame 5, a cooling water bag 8 fixedly mounted on the cooling shaft 7, the cooling water bag 8 abutting against the upper shaft 6; a transverse block 9 slidably mounted on the frame 1, the transverse block 9 being slidably engaged with the movable frame 5, and a correction shaft 10 rotatably mounted on the transverse block 9.

[0020] In this embodiment, in order to prevent the PVC roll from shrinking after cooling, the flattening process and the cooling process are carried out simultaneously. The preferred effect is that the PVC roll is also cooled to a suitable temperature when the flattening is completed. Since the PVC roll has a certain temperature when flattened, the upper shaft 6 and the lower shaft 4 are prone to heat up after working for a long time. This can easily lead to the problem that the PVC roll still has a high temperature after flattening and then continues to shrink, thus affecting the flattening effect. During operation, the PVC roll is conveyed by the belt 3 on the conveyor 2. When the PVC roll passes the lower shaft 4, it is flattened by the upper shaft 6 pressing down in conjunction with the belt 3. The lower shaft 4 serves as a support. Since the lower shaft 4 does not directly contact the PVC roll, the temperature of the PVC roll is transferred to the belt 3. Because the belt 3 is long and constantly running without constant contact with the PVC roll, it effectively cools the lower shaft 4. When the upper shaft 6 is pressed down, the cooling water bag 8 on the cooling shaft 7 that is in contact with it can contain a low-temperature water source, which can also cool the upper shaft 6. Ultimately, by cooling the lower shaft 4 and the upper shaft 6, the flattening effect is improved. The belt 3 and the lower shaft 4 can also be cooled by means of fan blowing. Furthermore, when flattening PVC rolls of the same specification, the upper shaft 6 can be pressed down to different heights to give the PVC rolls different thicknesses and widths. When the moving frame 5 drives the upper shaft 6 to press down, the transverse block 9, which is slidably engaged with the moving frame 5, will move laterally due to the inclination angle of the inclined surface between the two. Thus, when the upper shaft 6 presses down, the correction shaft 10 can move laterally to adapt to the different widths of the flattened PVC rolls, thereby achieving automatic guidance and correction of the flattened rolls and preventing the PVC rolls from shifting and failing to flatten the edges and corners of the PVC rolls, thus improving the flattening effect.

[0021] In some embodiments, to facilitate pressing down the upper shaft 6, a linear actuator 11 is fixedly installed on the frame 1. The linear actuator 11 can be an electric cylinder, and the output end of the linear actuator 11 abuts against the moving frame 5.

[0022] In some embodiments, to further improve the cooling effect on the upper shaft 6, a gear 12 is fixedly installed on the upper shaft 6, and a gear 13 is fixedly installed on the cooling shaft 7, with gear 12 and gear 13 meshing together. Through the meshing connection of gear 12 and gear 13, the cooling shaft 7 drives the cooling water bag 8 to rotate, ensuring that all parts inside the cooling water bag 8 can contact the upper shaft 6 for cooling. A temperature sensor can be installed inside the cooling water bag 8 to facilitate periodic replacement of the internal low-temperature water source.

[0023] In some embodiments, to facilitate the sliding engagement between the movable frame 5 and the transverse block 9, a locking block 14 is fixedly installed on the movable frame 5, and a locking groove 15 is provided on the transverse block 9. The locking block 14 is slidably engaged in the locking groove 15. By sliding the locking block 14 in the locking groove 15, when the correction shaft 10 exerts pressure on the PVC roll material for correction and guidance, the pressure can be transmitted through the locking block 14 to the movable frame 5, which can only move up and down, for balance.

[0024] In some embodiments, to facilitate the correction of the PVC roll material by the correction shaft 10, an L-shaped extension frame 16 is fixedly installed on the transverse block 9. The correction shaft 10 is rotatably mounted on the L-shaped extension frame 16, and the outer ring of the correction shaft 10 extends out of the L-shaped extension frame 16. Thus, only the outer ring of the correction shaft 10 contacts the edge of the PVC roll material, and the L-shaped extension frame 16 only facilitates the correction shaft 10 to approach the PVC roll material without contacting it.

[0025] In some embodiments, a water exchange nozzle 17 is fixedly installed on the cooling water bag 8 to facilitate the replacement of the low-temperature water source inside the cooling water bag 8. The water source is replaced by opening the water exchange nozzle 17, and the water exchange nozzle 17 is closed after replacement to prevent the cooling water bag 8 from leaking.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
