Description

Technical Field

[0001] This utility model relates to the field of coated paper cooling devices, specifically a coated paper cooling device that facilitates heat transfer. Background Technology

[0002] Coated paper is a composite material in which plastic particles are melted and uniformly coated onto the surface of paper using a coating machine. It is oil-proof, waterproof, and heat-sealing. The coating machine, also known as an extrusion casting laminating machine, is a type of extrusion molding machinery. It has advantages such as high degree of automation, simple operation, high production speed, uniform coating thickness, high adhesion, flat winding, environmental protection and pollution-free production, and saving labor and raw material costs. In the production equipment of coated paper, cooling rollers are usually required to absorb heat and cool down the coated paper to set its shape, so as to prevent the high-temperature coated paper from sticking together after winding, which would cause the product to be scrapped.

[0003] The existing equipment has the following shortcomings when in use: the cooling water channel design of the cooling roller is mostly a single inlet and outlet mode, and the water flow is prone to local stagnation in the channel, resulting in uneven temperature distribution on the roller surface, which affects the cooling and setting effect of the coated paper. For paper with a large thickness or a thick coating layer, single-sided roller contact cooling is difficult to quickly dissipate internal heat, resulting in low cooling efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling device for coated paper that facilitates heat transfer, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for coated paper that facilitates heat transfer, comprising an equipment box, a material box, a cooling roller A, a cooling roller B, and a cold air box. An electric telescopic rod is installed in the equipment box, and a mounting frame is installed at one end of the electric telescopic rod. The cooling roller A is rotatably mounted on the mounting frame. A cooling roller B, perpendicularly corresponding to the position of cooling roller A, is placed in the equipment box. An inner mandrel is provided in cooling roller A, and a cooling water channel is formed between the outer wall of cooling roller A and the inner mandrel. Connecting rings are provided between the two ends of the inner mandrel and the inner wall of cooling roller A. A water flow hole is circumferentially opened on the ring wall of the connecting ring, and the water flow hole communicates with the cooling water channel. An inlet pipe and an outlet pipe are respectively provided at both ends of cooling roller A, and the inlet pipe and outlet pipe are connected to a cooling water circulation device. Cooling roller B has the same structure as cooling roller A.

[0006] Using the above technical solution, during use, the raw paper on the feeding roller enters the feed box and comes to the bottom of the extrusion head. The coating material in the feed box is evenly coated on the surface of the raw paper through the extrusion head to form a coating layer. Then, the coated paper enters between cooling roller A and cooling roller B under the guidance of the guide roller. The mounting frame can be driven by the electric telescopic rod to move cooling roller A up and down, thereby adjusting the distance between cooling roller A and cooling roller B to meet the cooling requirements of coated paper of different thicknesses. By synchronously rolling and cooling the upper and lower surfaces of the coated paper, the cooling efficiency and shaping effect are improved. During this process, cooling water enters the connecting ring from the inlet pipe. Through the annularly distributed water outlet holes on the connecting ring, the cooling water flows evenly into the cooling water channel, making full contact with the roller and flowing continuously. This continuously removes the heat absorbed by the roller when it comes into contact with the coated paper. The water that has absorbed the heat enters from the water outlet holes on the other end of the connecting ring and is then discharged from the outlet pipe into the cooling water circulation equipment for cooling treatment before being reused. This completes the circulation of cooling water, effectively avoiding the water stagnation problem caused by single inlet and outlet water, making the temperature distribution on the roller surface more uniform, and improving the cooling and setting effect of the coated paper.

[0007] Preferably, a cold air box is installed in the equipment box, the cold air box has a channel, the cold air box has an air duct, the air duct is connected to the air blowing hole opened on the channel wall, an air inlet box is installed in the equipment box, the air inlet box is equipped with a fan and a filter screen, an air supply pipe is connected to the air inlet box, and the other end of the air supply pipe is connected to the air duct.

[0008] Using the above technical solution, the coated paper, after being cooled and shaped by the cooling roller, passes through the channel opened on the cold air box. The fan installed on the air inlet box is started, and the outside air is filtered by the filter screen on the air inlet box and then transported to the air duct through the air supply pipe. The air is then blown to both sides of the coated paper through the air blowing holes on the inner wall of the channel to further cool the coated paper. This effectively avoids the problem of secondary deformation caused by residual heat and further improves the dimensional stability of the coated paper.

[0009] Preferably, a material bin is installed on the equipment box, the material bin is connected to an extrusion head provided in the equipment box, and a stirring structure is installed on the material bin.

[0010] The above technical solution includes a drive motor, a stirring shaft, and stirring blades. The drive motor drives the stirring blades on the stirring shaft to rotate, which can stir the coating material in the material box, prevent the material from settling and stratifying due to static standing, ensure that the coating layer on the base paper has a uniform thickness, and improve product quality.

[0011] Preferably, the equipment box is equipped with a feeding roller and a receiving roller, and the receiving roller is equipped with a drive motor.

[0012] Using the above technical solution, the feeding roller is used to place the raw paper roll to be processed, and the taking-up roller is driven by the drive motor to wind up the processed coated paper, providing stable power traction for the entire processing of coated paper.

[0013] Preferably, a guide roller is installed in the equipment box.

[0014] Using the above technical solution, the guide roller can guide and tension the raw paper drawn from the feed roller, ensuring that the raw paper remains flat before entering the cooling roller group, and avoiding the impact of raw paper wrinkles on the subsequent coating and cooling setting effect.

[0015] Preferably, an auxiliary telescopic column is provided between the mounting bracket and the inner wall of the equipment box.

[0016] Using the above technical solution, the two ends of the auxiliary telescopic column are fixedly connected to the mounting frame and the inner wall of the equipment box, respectively. When the electric telescopic rod drives the mounting frame to move up and down to adjust the position of cooling roller A, the auxiliary telescopic column can provide stable support for the mounting frame, preventing the mounting frame from shaking or shifting during the movement, and ensuring that cooling roller A and cooling roller B always maintain a precise vertical correspondence, thereby ensuring a stable rolling cooling effect for coated paper of different thicknesses.

[0017] Compared with the prior art, the beneficial effects of this utility model are: The coated paper is guided by the feed rollers and enters between cooling rollers A and B. Cooling water enters the connecting ring from the inlet pipe and flows evenly into the cooling water channel through the annularly distributed water outlet holes on the connecting ring. It makes full contact with the roller body and flows, continuously carrying away the heat absorbed by the roller body when in contact with the coated paper. The water that has absorbed heat enters from the water outlet hole on the other end of the connecting ring and is discharged from the outlet pipe into the cooling water circulation equipment for cooling treatment and reuse. This completes the circulation of cooling water, effectively avoiding the water flow stagnation problem caused by single inlet and outlet water, making the temperature distribution on the roller body surface more uniform and improving the cooling and shaping effect of the coated paper.

[0018] The electric telescopic rod drives the mounting frame to move the cooling roller A up and down, thereby adjusting the distance between cooling roller A and cooling roller B to meet the cooling requirements of coated paper of different thicknesses. By synchronously rolling and cooling the upper and lower surfaces of the coated paper, the cooling efficiency and shaping effect are improved. With the help of the cold air box, the outside air is filtered by the filter screen on the air inlet box and then delivered to the air duct through the air supply pipe. It is then blown onto both sides of the coated paper through the air blowing holes on the inner wall of the duct to further cool the coated paper. This effectively avoids the problem of secondary deformation caused by residual heat and further improves the dimensional stability of the coated paper. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4This utility model provides an embodiment of a cooling device for coated paper that facilitates heat transfer, comprising an equipment box 1, a material box 4, a cooling roller A10, a cooling roller B11, and a cold air box 12. An electric telescopic rod 8 is installed in the equipment box 1, and a mounting frame 9 is installed at one end of the electric telescopic rod 8. The cooling roller A10 is rotatably mounted on the mounting frame 9. A cooling roller B11, perpendicularly corresponding to the position of the cooling roller A10, is placed in the equipment box 1. An inner mandrel 20 is provided in the cooling roller A10. A cooling water channel 21 is formed between the outer wall of the cooling roller A10 and the inner mandrel 20. A connecting ring 22 is provided between the two ends of the inner mandrel 20 and the inner wall of the cooling roller A10. A water flow hole 23 is circumferentially opened on the ring wall of the connecting ring 22. The water flow hole 23 is connected to the cooling water channel 21. A water inlet pipe 24 and a water outlet pipe 25 are respectively provided at both ends of the cooling roller A10. The water inlet pipe 24 and the water outlet pipe 25 are connected to a cooling water circulation device. The cooling roller B11 has the same structure as the cooling roller A10. In use, the raw paper on the feeding roller 2 enters the feed box 4 and comes to the bottom of the extrusion head 6. The coating material in the feed box 4 is evenly coated on the surface of the raw paper through the extrusion head 6 to form a coating layer. Then, the coated paper enters between the cooling roller A10 and the cooling roller B11 under the guidance of the guide roller 7. The mounting frame 9 can be driven by the electric telescopic rod 8 to move the cooling roller A10 up and down, thereby adjusting the distance between the cooling roller A10 and the cooling roller B11 to meet the cooling requirements of coated paper of different thicknesses. By synchronously rolling and cooling the upper and lower surfaces of the coated paper, the cooling efficiency and shaping effect are improved. During this process, cooling water enters the connecting ring 22 from the inlet pipe 24. Through the annularly distributed water flow holes 23 on the connecting ring 22, the cooling water flows evenly into the cooling water channel 21, making full contact with the roller and flowing. It continuously carries away the heat absorbed by the roller when it comes into contact with the coated paper. The water that has absorbed the heat enters from the water flow holes 23 on the other end of the connecting ring 22, and then exits from the outlet pipe 25 into the cooling water circulation equipment for cooling treatment and reuse. This completes the circulation of cooling water, effectively avoiding the water flow stagnation problem caused by single inlet and outlet water, making the surface temperature distribution of the roller more uniform and improving the cooling and shaping effect of the coated paper.

[0023] The equipment box 1 is equipped with a cold air box 12, which has a channel 13 and an air duct 14. The air duct 14 is connected to the air blowing holes 15 on the wall of the channel 13. The equipment box 1 is also equipped with an air inlet box 17, which has a fan 18 and a filter screen 19. An air supply pipe 16 is connected to the air inlet box 17, and the other end of the air supply pipe 16 is connected to the air duct 14. After being cooled and shaped by the cooling roller, the coated paper passes through the channel 13 in the cold air box 12. The fan 18 installed in the air inlet box 17 is started, and the outside air is filtered by the filter screen 19 in the air inlet box 17 and then delivered to the air duct 14 by the air supply pipe 16. The air is then blown onto both sides of the coated paper through the air blowing holes 15 on the inner wall of the channel 13, further cooling the coated paper and effectively avoiding secondary deformation caused by residual heat, thus further improving the dimensional stability of the coated paper.

[0024] A material bin 4 is installed on the equipment box 1, and the material bin 4 is connected to the extrusion head 6 provided in the equipment box 1. A stirring structure 5 is installed on the material bin 4. The stirring structure 5 includes a drive motor, a stirring shaft, and stirring blades. The drive motor drives the stirring blades on the stirring shaft to rotate, which can stir the coating material in the material bin 4, prevent the material from settling and stratifying due to static standing, ensure that the coating layer on the base paper has a uniform thickness, and improve product quality.

[0025] The equipment box 1 is equipped with a feeding roller 2 and a taking-up roller 3, and the taking-up roller 3 is equipped with a drive motor. The feeding roller 2 is used to place the raw paper roll to be processed, and the taking-up roller 3, driven by the drive motor, winds up the processed coated paper, providing stable power traction for the entire processing of coated paper.

[0026] The equipment box 1 is equipped with a guide roller 7. The guide roller 7 can guide and tension the raw paper drawn from the feed roller 2, ensuring that the raw paper remains flat before entering the cooling roller group, and avoiding the impact of raw paper wrinkles on the subsequent coating and cooling setting effect.

[0027] An auxiliary telescopic column is provided between the mounting frame 9 and the inner wall of the equipment box 1. The two ends of the auxiliary telescopic column are fixedly connected to the mounting frame 9 and the inner wall of the equipment box 1, respectively. When the electric telescopic rod 8 drives the mounting frame 9 to move up and down to adjust the position of the cooling roller A10, the auxiliary telescopic column can provide stable support for the mounting frame 9, preventing the mounting frame 9 from shaking or shifting during the movement, and ensuring that the cooling roller A10 and the cooling roller B11 always maintain a precise vertical correspondence, thereby ensuring a stable rolling cooling effect for coated paper of different thicknesses.

[0028] Working principle: During use, the raw paper on the feeding roller 2 enters the feed box 4 and comes to the bottom of the extruder 6. The coating material in the feed box 4 is evenly coated on the surface of the raw paper through the extruder 6 to form a coating layer. Then, the coated paper enters between the cooling roller A10 and the cooling roller B11 under the guidance of the guide roller 7. The electric telescopic rod 8 can drive the mounting frame 9 to move the cooling roller A10 up and down, thereby adjusting the distance between the cooling roller A10 and the cooling roller B11 to meet the cooling requirements of coated paper of different thicknesses. By synchronously rolling and cooling the upper and lower surfaces of the coated paper, the cooling efficiency and shaping effect are improved. During this process, cooling water enters the connecting ring 22 from the inlet pipe 24. Through the annularly distributed water flow holes 23 on the connecting ring 22, the cooling water flows evenly into the cooling water channel 21, making full contact with the roller and flowing continuously, carrying away the heat absorbed by the roller when in contact with the coated paper. The water, having absorbed heat, enters from the water flow holes 23 on the other end of the connecting ring 22, and then exits from the outlet pipe 25 into the cooling water circulation equipment for further cooling and reuse. This completes the circulation of cooling water, effectively avoiding the water stagnation problem caused by single inlet and outlet water flow, thus ensuring the smooth operation of the roller. The surface temperature distribution is more uniform, which improves the cooling and shaping effect of the coated paper. After being cooled and shaped by the cooling roller, the coated paper passes through the channel 13 opened on the cold air box 12. The fan 18 installed on the air inlet box 17 is started. The outside air is filtered by the filter screen 19 on the air inlet box 17 and then delivered to the air duct 14 by the air supply pipe 16. It is then blown to both sides of the coated paper through the air blowing holes 15 on the inner wall of the channel 13 to further cool the coated paper. This effectively avoids the problem of secondary deformation caused by residual heat and further improves the dimensional stability of the coated paper.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
