Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically a cooling device for nonwoven fabric production. Background Technology

[0002] Nonwoven fabric refers to a fabric-like product made from chemical fibers as the basic raw material and bonded together chemically (or thermally). Because it is not woven, it is also called nonwoven fabric. It is made by directly using polymer chips, short fibers or filaments to form a web through airflow or mechanical means, and then reinforced by hydroentangling, needle punching or hot rolling, and finally finished to form a nonwoven fabric.

[0003] As disclosed in CN220450474U, a cooling device for nonwoven fabric production has the following advantages: The nonwoven fabric is output via an unwinding roller, passing sequentially through a water tank and a cooling device. The output is limited by a roller 1 inside the water tank and a roller 2 on the inner wall of a support frame. Upon passing the base frame, a pressure plate removes excess water from the nonwoven fabric. It is then further cooled by the cooling device, and finally, a winding roller rewinds the cooled nonwoven fabric. The water tank and pressure plate ensure uniform cooling of the nonwoven fabric surface, improving the cooling effect. The aforementioned patent involves transferring the nonwoven fabric to water and then cooling it using a cooling device. Although a pressure plate squeezes out the water from the nonwoven fabric surface, it is difficult to completely remove the water. Residual liquid can penetrate the internal structure of the nonwoven fabric, affecting its physical properties such as strength and toughness. Furthermore, during the drying process, residual liquid can leave marks or spots, affecting the product's appearance quality.

[0004] Therefore, there is an urgent need for a cooling device for nonwoven fabric production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for nonwoven fabric production, which has the advantage of good cooling effect and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cooling device for nonwoven fabric production, comprising a carrying plate, with an unwinding roller and a take-up roller respectively arranged on both sides of the top of the carrying plate. Two fixing plates are fixedly connected to the top of the carrying plate, located between the unwinding roller and the take-up roller. Cooling roller 1, cooling roller 2, cooling roller 3, and cooling roller 4 are arranged sequentially from left to right on opposite sides of the two fixing plates. The front ends of cooling roller 1 and cooling roller 2 are rotatably connected to a conveying pipe 1. The rear ends of cooling roller 2 and cooling roller 3 are rotatably connected to a conveying pipe 2. The front ends of cooling roller 3 and cooling roller 4 are rotatably connected to a conveying pipe 3. The rear end of cooling roller 4 is rotatably connected to a transmission pipe. A cooling box is fixedly connected to the top of the carrying plate and to the rear side of the fixing plates. A water pump is installed in the inner cavity of the cooling box. The outlet pipe of the water pump is rotatably connected to the first cooling roller. The rear end of the transmission pipe extends through the inner cavity of the cooling box. The first, second, and third transmission pipes, the transmission pipe, and the outlet pipe of the water pump are all fixedly connected to the fixed plate. The inner cavities of the first, second, third, and fourth cooling rollers are all provided with spiral holes. The spiral holes are respectively connected to the first, second, and third transmission pipes, the transmission pipe, and the outlet pipe of the water pump. The top of the two fixed plates are fixedly connected to the first air guide plate. The top of the first air guide plate is connected to the housing. A fan is installed in the inner cavity of the housing. The opposite sides of the two fixed plates are fixedly connected to the second air guide plate. Three air supply pipes are connected to both sides of the first air guide plate. The air supply pipes extend through to one side of the fixed plate and are connected to the second air guide plate.

[0007] Furthermore, as a preferred embodiment of this utility model, bolts are provided through the four corners of the top of the carrying plate.

[0008] Furthermore, as a preferred embodiment of this invention, the top of the cooling box is connected to a water injection pipe, and the inner wall of the water injection pipe is smooth.

[0009] Furthermore, as a preferred embodiment of this invention, the inner cavity of the housing is filled with a filter screen, which is located above the fan.

[0010] Furthermore, as a preferred embodiment of this utility model, the cooling roller one, cooling roller two, cooling roller three, and cooling roller four are all made of chrome-plated steel.

[0011] Beneficial Effects: The technical solution of this application has the following advantages: This utility model has the advantage of good cooling effect. In actual use, a water pump is used as a power source to transport the coolant, allowing the coolant to circulate within the inner cavity of the spiral hole. This not only ensures the uniform distribution of the coolant but also enhances the cooling effect through its circulatory characteristics. When the nonwoven fabric passes through cooling roller one, cooling roller two, cooling roller three, and cooling roller four in sequence, the chrome-plated steel material of the cooling rollers plays a crucial role. Chrome-plated steel has good thermal conductivity and can quickly absorb the heat from the surface of the nonwoven fabric. This heat is dissipated through the chrome-plated steel material. The heat is transferred to the internal circulating coolant, which carries away the heat, thus achieving primary heat dissipation for the nonwoven fabric and effectively reducing its temperature, ensuring the stability of its production quality. Secondly, two air guide plates are installed. Air guide plate one is located above the nonwoven fabric and blows cold air to directly cool it. At the same time, air guide plate two is located below the nonwoven fabric and blows cold air to cool the bottom of the nonwoven fabric. This design of blowing cold air from both above and below ensures that the nonwoven fabric can be fully and evenly cooled, thus achieving secondary heat dissipation for the nonwoven fabric.

Two fixing plates 4 are fixedly connected to the top of the carrier plate 1, located between the unwinding rollers 2 and take-up rollers 3. From left to right, cooling rollers 5, 6, 7, and 8 are arranged sequentially on opposite sides of the two fixing plates 4.

The front ends of cooling rollers 7 and 8 are rotatably connected to a conveying pipe 11. The rear end of cooling roller 8 is rotatably connected to a transmission pipe 12. A cooling box 13 is fixedly connected to the top of the carrier plate 1 and to the rear side of the fixing plates 4. A water pump 14 is installed inside the cooling box 13. The outlet pipe of the water pump 14... The transmission pipe 12 is rotatably connected to the cooling roller 5. The rear end of the transmission pipe 12 extends into the inner cavity of the cooling box 13. The water outlet pipes of the first transmission pipe 9, the second transmission pipe 10, the third transmission pipe 11, the transmission pipe 12, and the water pump 14 are all fixedly connected to the fixed plate 4. The inner cavities of the cooling roller 5, the second cooling roller 6, the third cooling roller 7, and the fourth cooling roller 8 are all provided with spiral holes 15. The spiral holes 15 are respectively connected to the water outlet pipes of the first transmission pipe 9, the second transmission pipe 10, the third transmission pipe 11, the transmission pipe 12, and the water pump 14. The top of the two fixed plates 4 are fixedly connected to the air guide plate 16. The top of the air guide plate 16 is connected to the housing 17. The inner cavity of the housing 17 is provided with a fan 18. The two fixed plates 4 are fixedly connected to the opposite side of the air guide plate 19. The two sides of the air guide plate 16 are connected to three air supply pipes 20. The air supply pipes 20 extend to one side of the fixed plate 4 and are connected to the air guide plate 29.

[0022] Specifically, bolts 21 are installed through the four corners of the top of the loading plate 1.

[0023] In this embodiment, the bolts 21 are used to install and fix the load plate 1, thereby improving the load stability of the load plate 1.

[0024] Specifically, the top of the cooling box 13 is connected to a water injection pipe 22, and the inner wall of the water injection pipe 22 is smooth.

[0025] In this embodiment, the water injection pipe 22 serves to input coolant into the inner cavity of the cooling tank 13, thereby improving the rationality of the structural layout.

[0026] Specifically, the inner cavity of the housing 17 is filled with a filter screen 23, which is located above the fan 18.

[0027] In this embodiment, the filter 23 filters the air entering the inner cavity of the housing 17, thus preventing it from affecting the hygienic effect of the non-woven fabric.

[0028] Specifically, cooling roller 1 (5), cooling roller 2 (6), cooling roller 3 (7), and cooling roller 4 (8) are all made of chrome-plated steel.

[0029] In this embodiment, the use of chrome-plated steel accelerates the heat absorption of the non-woven fabric, thereby quickly transferring heat to the cooling water.

[0030] The working principle and usage process of this utility model are as follows: The nonwoven fabric is output using the unwinding roller 2. The nonwoven fabric then passes over the surfaces of cooling rollers 5, 6, 7, and 8, and is finally wound up by the take-up roller 3. During the transmission process, the water pump 14 and fan 18 are activated. The water pump 14 extracts the coolant from the inner cavity of the cooling tank 13 and transmits it through the conveying pipes 9, 10, and 11 into the inner cavities of cooling rollers 5, 6, 7, and 8. Since the inner cavities of cooling rollers 5, 6, 7, and 8 are all provided with spiral holes 15, the direction of these spiral holes 15 not only allows the coolant to evenly cover the inner cavities of the cooling rollers, but also improves the heat exchange efficiency of the cooling rollers through their unique direction. The cooling rollers are made of chrome-plated steel, a material with… With excellent thermal conductivity, when the nonwoven fabric comes into contact with the cooling roller, the heat on the surface of the nonwoven fabric is quickly transferred to the cooling roller and carried away by the cooling liquid, thus achieving primary heat dissipation of the nonwoven fabric. At this time, when the nonwoven fabric is being conveyed, the unwinding roller 2 and the winding roller 3 work together to drive the cooling rollers 5, 6, 7, and 8 to rotate, which not only helps to ensure the smooth transport of the nonwoven fabric but also further enhances the cooling effect. Secondly, when the fan 18 starts, the cold air from the outside is blown to the top of the nonwoven fabric through the air guide plate 16, providing direct air cooling for the nonwoven fabric. At the same time, some of the cold air is transmitted through the air supply pipe 20 into the inner cavity of the air guide plate 19 and blown to the bottom of the nonwoven fabric through the air guide plate 19. Both the top and bottom surfaces of the nonwoven fabric can receive sufficient air cooling, thus ensuring the temperature stability of the nonwoven fabric during the production and processing process.
