They have properties such as insulation, corrosion resistance and easy processing, and are widely used in sheet plastic products in packaging, construction and other fields.

[0003] In the production and processing of PVC sheets, roller presses are usually required to improve their physical properties and enhance their quality. Wear-resistant PVC sheet roller presses use wear-resistant rollers to roll PVC sheets. Through the pressure during the rolling process, the internal structure of the sheet is densified, thereby enhancing the wear resistance of the sheet and meeting the needs of demanding application scenarios such as building decoration and industrial packaging.

[0004] However, existing wear-resistant PVC sheet rolling machines have the following shortcomings:

[0005] In the existing technology, wear-resistant PVC sheet rolling machines often require adjusting the distance between the two rolling rollers to adapt to sheets of different thicknesses and adjust rolling process parameters. Therefore, both rolling rollers need to be equipped with motor drives, which makes the electrical system of the equipment more complex, increases the difficulty of wiring layout and control, and significantly increases the cost. In addition, the dual-motor drive system is prone to synchronization problems, resulting in uneven force on the sheet during the rolling process.

[0006] Therefore, we propose a wear-resistant PVC sheet rolling machine to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a wear-resistant PVC sheet rolling machine. By using a transmission mechanism of motor drive combined with bevel gear set, one motor can drive two rolling rollers to rotate synchronously, efficiently completing the rolling operation. With the help of electric push rod drive and relying on the limiting function of the locking component, the distance between the two rolling rollers can be easily and accurately adjusted, and this process will not interfere with the normal transmission of the bevel gear, thus solving the problems mentioned in the background art.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 -Appendix Figure 4 As shown, this utility model provides a technical solution: a wear-resistant PVC sheet rolling machine, including a rolling machine frame 1, a cylinder 2 fixedly installed on the top of the rolling machine frame 1, and the telescopic end of the cylinder 2 movably passing through the interior of the rolling machine frame 1. A sliding frame 3 is fixedly connected to the telescopic end of the cylinder 2, and the outer wall of the sliding frame 3 is slidably embedded in the interior of the rolling machine frame 1. First bearings 4 are fixedly inserted into the inner walls of both the rolling machine frame 1 and the sliding frame 3. Rolling rollers 5 are fixedly inserted between the interiors of the two sets of first bearings 4. First cones are fixedly sleeved on the outer walls of the two rolling rollers 5. Gear 6, the outer walls of the two first bevel gears 6 are meshed with second bevel gears 7, two bearing seats 8 are fixedly installed on one side of the outer wall of the rolling mill frame 1, a rotating shaft 9 is fixedly inserted between the two bearing seats 8, and the outer wall of the rotating shaft 9 is fixedly inserted into the interior of one of the two second bevel gears 7, a drive motor 10 is fixedly connected to the bottom of the rotating shaft 9, two locking blocks 11 are fixedly connected to the outer wall of the rotating shaft 9, two locking slots 12 are opened on the top of the other of the two second bevel gears 7, and the outer walls of the two locking blocks 11 are movably inserted into the interior of the two locking slots 12.

[0026] The overall effect of Embodiment 1 is that, during use, when the drive motor 10 is started, the motor output drives the two second bevel gears 7 to rotate synchronously, which in turn drives the two first bevel gears 6 meshing with them to rotate. The two first bevel gears 6 respectively drive the two rolling rollers 5 to rotate, thereby performing a rolling operation on the PVC sheet located between the two rolling rollers 5. Moreover, this method only requires one motor to drive the two rolling rollers 5 to rotate, reducing the number of motors used, which not only reduces the cost of equipment investment, but also simplifies the electrical control system and improves the stability of equipment operation. When it is necessary to adjust the distance between the two rolling rollers 5, the cylinder 2 is started first. The telescopic end of cylinder 2 drives the sliding frame 3 to move up and down in the vertical direction, which in turn drives the top rolling roller 5 mounted on the sliding frame 3 to move synchronously. At this time, through the sliding cooperation of two locking blocks 11 and two locking slots 12, it is ensured that the bevel gear set connected to the top rolling roller 5 can move smoothly in the vertical direction. At the same time, the rotation of the rotating shaft 9 can drive the top bevel gear set to rotate, so that the adjustment of the distance between the two rolling rollers 5 will not cause any interference to the transmission components. This ensures that the transmission system can still work stably and efficiently during the change of the distance between the rolling rollers 5, thereby realizing the precise rolling operation of PVC sheets of different thicknesses and improving the versatility and processing accuracy of the equipment.

[0027] Example 2, as Figure 2-4 As shown, a heat sink 13 is fixedly connected to the outer wall of the rolling mill frame 1. Two mounting slots 14 are opened on the outer wall of the heat sink 13. An air intake fan 15 is fixedly inserted into the inner wall of one of the two mounting slots 14, and an exhaust fan 16 is fixedly inserted into the inner wall of the other of the two mounting slots 14. Two embedding slots 17 are opened on the top of the heat sink 13. Filter plates 18 are movably inserted into the inner wall of both embedding slots 17. Handles 19 are fixedly connected to the top of both filter plates 18. Two second bearings 20 are fixedly inserted into the inner wall of the rolling mill frame 1. A conveying roller 21 is fixedly inserted between the interior of the two second bearings 20. A winding roller 22 is movably inserted into the inner wall of the rolling mill frame 1.

[0028] The overall effect achieved in Embodiment 2 is as follows: During the rolling operation, the intake fan 15 and the exhaust fan 16 are turned on first. After the intake fan 15 starts running, it generates strong air pressure, forcibly introducing cold air from the outside into the heat sink 13. After the exhaust fan 16 starts, it creates suction, causing the inside of the heat sink 13 to be in a negative pressure state. In this way, under the synergistic effect of the intake fan 15 and the exhaust fan 16, the outside air flows directionally from the intake fan 15 side to the exhaust fan 16 side, carrying out air cooling of the PVC sheet passing through the inside of the heat sink 13. To ensure the temperature of the sheet remains within a suitable range during the rolling process, excessive temperature can negatively impact sheet performance and rolling quality. Furthermore, the kinetic energy of the flowing air can blow away dust and impurities from the surface of the PVC sheet, effectively cleaning it. During continuous airflow, the left-side filter plate 18 purifies and filters the incoming air, removing impurities and improving air quality. The right-side filter plate 18 filters the exhaust gas, trapping dust and other pollutants to ensure a clean working environment and reduce pollution to the surrounding environment.

[0029] The working principle of the entire equipment is as follows: During use, the distance between the two rolling rollers 5 needs to be adjusted according to the thickness of the PVC sheet. The operator first starts the cylinder 2. The telescopic end of the cylinder 2 drives the sliding frame 3 to move smoothly up and down in the vertical direction. The sliding frame 3 then drives the top rolling rollers 5 to move synchronously, thus achieving precise control of the distance between the two rolling rollers 5. During this process, thanks to the sliding cooperation of the two locking blocks 11 and the two locking slots 12, as well as the meshing of the bevel gear set, the top second bevel gear 7 can move freely in the vertical direction. Furthermore, the rotation of the rotating shaft 9 drives the top second bevel gear 7 to rotate, ensuring that the adjustment of the distance between the two rolling rollers 5 does not interfere with the transmission of the bevel gear assembly. When the distance adjustment is completed and the rolling operation is ready, the drive motor 10 is started. The output end of the drive motor 10 drives the two second bevel gears 7 to rotate. The two second bevel gears 7 then drive the two meshing first bevel gears 6 to rotate synchronously. The two first bevel gears 6 respectively drive the two rolling rollers 5 to rotate at high speed, thereby performing a rolling operation on the PVC sheet between the two rolling rollers 5. Simultaneously, the intake fan 15 and exhaust fan 16 are activated. The intake fan 15 generates strong air pressure, continuously drawing in cool outside air into the heat sink 13. The exhaust fan 16 generates suction, creating a negative pressure inside the heat sink 13. This causes outside air to flow directionally from the intake fan 15 side to the exhaust fan 16 side, cooling the PVC sheet passing through the heat sink 13 and ensuring the sheet maintains a suitable temperature during the rolling process. Furthermore, the kinetic energy of the flowing air can further cool the PVC sheet. The dust and impurities on the surface are blown away, which serves to clean the sheet. During the continuous air flow, the left filter plate 18 purifies and filters the intake air, effectively removing impurity particles in the air and improving the air quality of the intake air. The right filter plate 18 filters the exhaust air, trapping dust and other pollutants in the exhaust gas to ensure a clean working environment. In addition, the operator can easily remove the two filter plates 18 from the corresponding mounting slots 17 by pulling the two handles 19, which greatly facilitates the cleaning, maintenance and replacement of the filter plates 18.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
