The PP conveyor belt overcomes some disadvantages of traditional belt conveyors, such as tearing, puncturing, and corrosion, and provides a safe, fast, and easy-to-maintain conveying method. During the production process of the PP conveyor belt, the conveyor belt after processes such as extrusion and calendering needs to be cooled and shaped to ensure its dimensional stability and physical properties.

[0003] Currently, the common cooling methods are mostly air cooling or water cooling, but there are problems such as uneven cooling and low cooling efficiency, which affect the quality and production efficiency of the conveyor belt. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the following disadvantages existing in the prior art: there are problems such as uneven cooling and low cooling efficiency, which affect the quality and production efficiency of the conveyor belt, and a cooling and shaping device for PP conveyor belts is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A cooling and shaping device for PP conveyor belts includes a bed frame. Above the bed frame, there are multiple cooling rollers. A cooling cavity is opened inside the cooling rollers. Both ends of the cooling rollers are fixedly communicated with rotating pipes. The rotating pipes are rotationally installed on the bed frame through fixing parts.

One end of the spring rod far away from the cross bar is fixedly installed with a scraping rod. The scraping rod is in sliding contact with the inner wall of the cooling cavity.

[0009] Preferably, a cavity is formed inside the scraping rod, and a plurality of spray pipes are obliquely installed on the scraping rod. The spray pipes are communicated with the inside of the cavity. A liquid inlet pipe communicated with the inside of the cavity is fixedly connected to the scraping rod, and a water injection assembly for inputting cooling water into the cavity is arranged on the cross bar.

[0010] Preferably, the water injection assembly includes a water collecting cylinder fixedly installed on the cross bar, a water injection pipe fixedly installed at one end of the water collecting cylinder, a moving plate sealingly and slidably inserted into the water collecting cylinder, a moving rod slidably installed in the water collecting cylinder through an elastic member, and a transmission member for driving the moving rod to move.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-6 , a cooling and shaping device for a PP conveyor belt, including a bed frame 1, a plurality of cooling rollers 2 are arranged above the bed frame 1, a cooling cavity is opened inside the cooling roller 2, both ends of the cooling roller 2 are fixedly communicated with a rotating pipe 3, the rotating pipe 3 is rotatably installed on the bed frame 1 through a fixing member, a refrigerator 4 is fixedly installed on the bed frame 1, the refrigerator 4 is provided with a water inlet pipe and a water outlet pipe, adapter pipes 5 are respectively installed on both sides of the bed frame 1, one end of the water inlet pipe and the water outlet pipe are respectively communicated with the two adapter pipes 5, one end of each of the plurality of rotating pipes 3 is rotatably sleeved with a connecting sleeve 6, one end of each of the plurality of connecting sleeves 6 is connected with a connecting pipe 7, and the ends of the plurality of connecting pipes 7 away from the connecting sleeves 6 are respectively communicated with the two adapter pipes 5.

[0025] The refrigerator 4 can generate cooling water and transport it into the adapter pipe 5 through the water outlet pipe. The other adapter pipe 5 is connected to the water inlet pipe, and the cooling water can be returned to the refrigerator 4 through the water inlet pipe to realize the recycling of the cooling water.

[0026] The PP conveyor belt is alternately inserted between multiple cooling rollers 2. When the PP conveyor belt moves on the bed frame 1, it drives multiple cooling rollers 2 to rotate. Cooling water flows into the connecting pipe 7 through the rotating connecting pipe 5, and then flows into the cooling cavity opened inside the cooling roller 2 through the connecting sleeve 6 and the rotating pipe 3. The cooling water flowing out of the cooling cavity will flow back to the refrigerator 4 through another rotating connecting pipe 5. When the cooling water flows in the cooling cavity, it will reduce the temperature of the surface of the cooling roller 2. By contacting the PP conveyor belt with multiple cooling rollers 2, the upper and lower surfaces of the PP conveyor belt can be cooled simultaneously, with uniform cooling and high cooling efficiency, effectively improving the production quality and production efficiency of the PP conveyor belt.

[0027] A cross bar 8 is arranged inside the cooling cavity. The two ends of the cross bar 8 respectively pass through two rotating pipes 3 and are fixedly connected to two connecting sleeves 6 respectively. A spring rod 9 is fixedly installed on the cross bar 8. One end of the spring rod 9 away from the cross bar 8 is fixedly installed with a scraping rod 10. The scraping rod 10 is in sliding contact with the inner wall of the cooling cavity. Under the action of the elastic force of the spring rod 9, the scraping rod 10 contacts the inner wall of the cooling cavity. The two ends of the cross bar 8 are fixedly connected to two connecting sleeves 6 respectively. When the cooling roller 2 rotates, the two connecting sleeves 6 will not rotate. Therefore, when the cooling roller 2 rotates, the scraping rod 10 will slide relative to the inner wall of the cooling cavity. Under the action of the scraping rod 10, the water groove on the inner wall of the cooling cavity can be removed, avoiding the accumulation of the water groove and affecting the cooling effect of the cooling roller 2.

[0028] A cavity is opened inside the scraping rod 10. A plurality of spray pipes 20 are obliquely installed on the scraping rod 10. The spray pipes 20 are communicated with the inside of the cavity. A liquid inlet pipe 11 communicated with the inside of the cavity is fixedly connected to the scraping rod 10. A water injection assembly for injecting cooling water into the cavity is arranged on the cross bar 8. The water injection assembly includes a water collecting cylinder 12 fixedly installed on the cross bar 8, a water injection pipe 13 fixedly installed at one end of the water collecting cylinder 12, a moving plate 14 sealed and slidably inserted into the water collecting cylinder 12, a moving rod 15 slidably installed in the water collecting cylinder 12 through an elastic member, and a transmission member for driving the moving rod 15 to move. One end of the moving rod 15 is fixedly connected to the moving plate 14. One end of the liquid inlet pipe 11 is connected to the water collecting cylinder 12. A first one-way valve that only allows liquid to flow from the water collecting cylinder 12 into the cavity is arranged in the liquid inlet pipe 11. A second one-way valve that only allows liquid to flow from the cooling cavity into the water collecting cylinder 12 is arranged in the water injection pipe 13.

[0029] The elastic member includes a bracket 16 fixedly installed at one end of the water collecting cylinder 12 and a telescopic spring 17 sleeved on the moving rod 15. A moving hole is opened on the bracket 16. The moving rod 15 is slidably inserted into the moving hole. The two ends of the telescopic spring 17 are respectively fixedly connected to the bracket 16 and the moving plate 14. The moving rod 15 is horizontally slidably installed on the water collecting cylinder 12 through the bracket 16. When the moving rod 15 moves, it will drive the moving plate 14 to move together.

[0030] The transmission components include an arc-shaped guide block 18 fixedly installed on the inner wall of the cooling chamber through a support block and an L-shaped transmission block 19 fixedly installed at one end of the moving rod 15. The transmission block 19 is in sliding contact with the arc-shaped guide block 18.

[0031] During the rotation of the cooling roller 2, it will drive the arc-shaped guide block 18 to rotate around the cross bar 8 and contact the transmission block 19 during the rotation. When the transmission block 19 contacts the arc-shaped guide block 18, the transmission block 19 will move along the inclined surface of the arc-shaped guide block 18, thereby driving the moving rod 15 to move away from the water collecting cylinder 12 and driving the moving plate 14 to move. The telescopic spring 17 is compressed. At this time, the cooling water in the cooling chamber will be sucked into the water collecting cylinder 12 through the water injection pipe 13. When the transmission block 19 is separated from the arc-shaped guide block 18, under the action of the elastic force of the telescopic spring 17, it drives the moving plate 14 to move towards the water collecting cylinder 12. At this time, the cooling water in the water collecting cylinder 12 will be squeezed into the cavity opened inside the scraping rod 10 through the liquid inlet pipe 11, and then sprayed out through multiple spray pipes 20. The sprayed cooling water will impact on the inner wall of the cooling chamber, thereby further improving the cleaning of the water groove.

[0032] In the present utility model, the PP conveyor belt is alternately inserted between multiple cooling rollers 2. When the PP conveyor belt moves on the bed frame 1, it will drive multiple cooling rollers 2 to rotate. The cooling water will flow into the connecting pipe 7 through the adapter pipe 5, and then flow into the cooling chamber opened inside the cooling roller 2 through the connecting sleeve 6 and the rotating pipe 3. When the cooling water flows in the cooling chamber, it will reduce the temperature on the surface of the cooling roller 2. By contacting the PP conveyor belt with multiple cooling rollers 2, the upper and lower surfaces of the PP conveyor belt can be cooled simultaneously, with uniform cooling and high cooling efficiency, effectively improving the production quality and production efficiency of the PP conveyor belt.

[0033] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
