Description

Technical Field

[0001] This utility model relates to the field of PVC roll production technology, specifically to a high-temperature conveying roller for anti-sticking PVC rolls. Background Technology

[0002] Polyvinyl chloride (PVC) rolls are widely used in numerous fields due to their excellent waterproof, abrasion-resistant, and chemical corrosion-resistant properties. In the construction industry, PVC rolls are commonly used for roof waterproofing, basement damp-proofing, and interior flooring, effectively isolating moisture from external corrosion and extending the building's lifespan. In the packaging industry, PVC rolls can be made into various packaging films and bags; their good flexibility and transparency protect products while facilitating product display. In the industrial sector, PVC rolls are used as conveyor belts and anti-corrosion linings to meet the needs of special working conditions. With the continuous growth of market demand, the PVC roll industry is showing a sustained development trend.

[0003] During the production process, PVC rolls are prone to sticking to the surface of the conveyor rollers due to their inherent stickiness and the effects of high temperatures. Once stuck, this can cause misalignment during transport, preventing the rolls from forming properly in subsequent processing steps, thus affecting product quality and resulting in a large number of defective products. Furthermore, cleaning the stuck PVC rolls requires frequent machine shutdowns, significantly reducing production efficiency, increasing costs, and potentially causing electrical malfunctions and other safety issues due to frequent start-ups and shutdowns.

[0014] Beneficial effects

[0015] This invention provides a high-temperature conveyor roller for preventing sticking of PVC rolls. Compared with the prior art, it has the following advantages:

[0016] (1) The anti-stick PVC roll high temperature conveying roller reduces the adhesion of the conveying roller body from the surface through the anti-stick coating. Combined with the combination of spiral channel and heat sink, it enhances the heat absorption capacity of coolant and efficiently cools down from the inside of the conveying roller body, reducing the possibility of PVC roll sticking to the roller surface due to high temperature.

[0017] (2) The anti-stick PVC roll high temperature conveying roller uses a blower to blow air to cool the surface of the conveying roller body, further reducing the possibility of PVC roll sticking to the roller body surface due to high temperature; and by setting air distribution plates on both sides of the bottom end of the conveying roller body, the air blown out of the air outlet is prevented from blowing directly onto the PVC roll, which would affect the stability of PVC roll conveying. Furthermore, by opening drainage holes on the surface of the air distribution plate, the air is blown out through the drainage holes to form a uniform and gentle airflow, further reducing the impact force on the PVC roll.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1-4 A high-temperature conveying roller for non-stick PVC rolls includes a main body 1, an air-cooling cooling mechanism 2 at the upper end of the main body 1, and a water supply mechanism 3 on one side of the main body 1.

[0026] The main body 1 of the device includes a bottom mounting plate 11, a conveying roller body 13, and a return pipe 18. The upper end of the bottom mounting plate 11 is fixedly connected to a mounting column 12. The two ends of the conveying roller body 13 are fixedly connected to a rotary joint 17. The fixed end of the rotary joint 17 is fixedly connected to the inner side of the top end of the mounting column 12. The two ends of the conveying roller body 13 are rotatably connected to the mounting column 12 through the rotary joint 17. The outer surface of the conveying roller body 13 is provided with an anti-stick coating 14. The interior of the conveying roller body 13 is provided with a spiral channel 15. The inner wall of the spiral channel 15 is evenly distributed with heat sinks 16. The heat sinks 16 are perpendicular to the spiral channel 15 and fixedly connected to the conveying roller body 13.

[0027] The water supply mechanism 3 includes a water tank 31, a booster pump 32 is fixedly installed on the top of the water tank 31, and a water inlet 35 is provided at one point on the top of the water tank 31.

[0028] The input end of the booster pump 32 is fixedly connected to a water pump pipe 33. The end of the water pump pipe 33 away from the booster pump 32 is fixedly connected to the water tank 31 and extends to the bottom of the water tank 31. The output end of the booster pump 32 is fixedly connected to a water delivery pipe 34.

[0029] The end of the water supply pipe 34 away from the booster pump 32 is fixedly connected to the fixed end of the rotary joint 17, the input end of the return pipe 18 is fixedly connected to the fixed end of the rotary joint 17, and the output end of the return pipe 18 is fixedly connected to the water tank 31.

[0030] The water supply pipe 34 is connected to the input end of the spiral channel 15, and the return pipe 18 is connected to the output end of the spiral channel 15.

[0031] In this embodiment, an anti-stick coating 14 is provided on the outer surface of the conveyor roller body 13. The anti-stick coating 14 is a polytetrafluoroethylene coating, which effectively reduces the adhesion between the PVC roll and the roller surface due to its extremely low surface energy and good chemical stability. The rotary joint 17 ensures that the two ends of the spiral channel 15 can still be connected to the water supply pipe 34 and the return pipe 18 when the conveyor roller body 13 rotates. The spiral channel 15 is provided inside the conveyor roller body 13, and heat sinks 16 are provided on the surface of the spiral channel 15, which increases the contact area and contact time between the coolant and the roller, allowing the coolant to more fully remove the heat from the roller. The water tank 31 can store the coolant. The coolant is extracted by the pressure pump 32 and injected into the conveyor roller body 13 to cool the conveyor roller body 13. After passing through the spiral channel 15, the coolant flows back to the water tank 31 through the return pipe 18. The conveyor roller body 13 is cooled by circulating water cooling with coolant, which reduces the possibility of the PVC roll sticking to the roller surface due to high temperature.

[0032] Example 2:

[0033] Please see Figure 1-2 This embodiment provides a technical solution based on embodiment one: the air-cooled cooling mechanism 2 includes a blower 21, a ventilation pipe 23 and an airflow distribution plate 25. The ventilation pipe 23 is located directly below the conveyor roller body 13 and its two ends are fixedly connected to the mounting column 12. Multiple equidistant air outlets 24 are fixedly connected to the top surface of the ventilation pipe 23.

[0034] The output end of the blower 21 is fixedly connected to the air supply pipe 22, and the end of the air supply pipe 22 away from the blower 21 is fixedly connected to the ventilation pipe 23.

[0035] The two ends of the airflow distribution plate 25 are fixedly connected to the mounting column 12. The surface of the airflow distribution plate 25 is evenly distributed with sludge holes 26. The airflow distribution plate 25 is symmetrically distributed on the front and rear sides of the conveyor roller body 13. The airflow distribution plate 25 is set at a 30° angle with the conveyor roller body 13.

[0036] In this embodiment, airflow is blown out by blower 21, and the airflow enters the ventilation pipe 23 through air supply pipe 22. It is then blown onto the bottom surface of the conveyor roller body 13 through air outlet 24 to cool the surface of the conveyor roller body 13, further reducing the possibility of PVC rolls sticking to the roller surface due to high temperature. By setting airflow distribution plates 25 on both sides of the bottom end of the conveyor roller body 13, the airflow blown out of air outlet 24 is prevented from blowing directly onto the PVC roll, which would affect the stability of PVC roll conveying. Furthermore, by opening drainage holes 26 on the surface of airflow distribution plates 25, the airflow is blown out through drainage holes 26 to form a uniform and gentle airflow, further reducing the impact force on the PVC roll.
