Description

Technical Field

[0001] This utility model relates to the technical field of equipment for PET monofilament production, specifically a cooling device for PET monofilament manufacturing. Background Technology

[0002] FIBCs and woven bags are flexible packaging containers commonly used in daily life, and are made from flat yarns and components.

[0003] The flat yarn production unit melts PET material to make plastic film, which is then drawn, cooled, and cut into flat yarns to produce woven fabric. After sewing or heat sealing, it is made into container bags or woven bags.

[0004] Traditional PET monofilament cooling devices typically use a single cooling water tank. After the filament bundle is immersed in the tank for initial cooling, a large amount of cooling water adheres to its surface. If it directly enters subsequent processes, this residual moisture will not only affect drying efficiency and increase energy consumption, but may also cause defects or uneven performance on the monofilament surface due to uneven evaporation of water droplets. In addition, the guide rollers in traditional cooling devices are usually in fixed positions, making it difficult to flexibly adjust the tension and cooling contact path, and making it difficult to adapt to the production needs of monofilaments of different specifications. Cooling efficiency and adaptability need to be improved. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a cooling device for PET monofilament manufacturing, thus solving the aforementioned technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for PET monofilament manufacturing, comprising a device body, a cavity inside the device body, a maintenance cover hinged to the top of the device body, and passages communicating with the outside on both inner walls of the cavity. Two transmission boxes protrude from the cavity, and transmission chambers are formed inside the transmission boxes. Two transmission sliders are slidably installed in the transmission chambers. A transmission gear is rotatably installed at the center of the transmission chamber. Both transmission sliders have tooth grooves that mesh with the transmission gear. A guide roller is connected between every two transmission sliders on the same horizontal plane. A servo motor is installed on the device body, and the output shaft of the servo motor is installed on one of the transmission gears. A cooling pool is provided inside the cavity, and a sponge block is slidably installed on the maintenance cover.

[0009] Preferably, the cooling pool is located directly below one of the guide rollers, and the sponge block is located directly above the other guide roller and abuts against it.

[0010] Preferably, the inspection cover is provided with a blower mechanism, the blower mechanism is provided with multiple cooling fans, and a filter screen is fastened to the top of the blower mechanism.

[0011] Preferably, two symmetrical sliding rods are slidably installed on the inspection cover, a sponge block is installed at the bottom of the two sliding rods, and the same connecting plate is installed at the top of the two sliding rods.

[0012] Preferably, each of the two slide rods is fitted with a compression spring, one end of which abuts against the inspection cover, and the other end of which abuts against the sponge block.

[0013] Preferably, both guide rollers have multiple annular grooves formed along the axial direction.

[0014] Preferably, two guide rods are arranged inside the transmission cavity, and each of the two transmission sliders inside the transmission cavity has a sliding hole adapted to the guide rod.

[0015] Compared with the prior art, this utility model provides a cooling device for manufacturing PET monofilaments, which has the following beneficial effects: This utility model, through the cooperation of a transmission slider, transmission gear and guide roller and other structures, allows the PET monofilaments to pass through two through ports and be wound around two guide rollers respectively. This allows the PET monofilaments to pass through the cooling pool for cooling, and then be wiped and dried by a sponge block and a blower mechanism, keeping the cooled PET monofilaments relatively dry. Furthermore, the servo motor drives the transmission gear to rotate, thereby moving the two transmission sliders away from each other. This allows the PET monofilaments to be easily threaded onto the two guide rollers, and also allows the PET monofilaments to remain immersed in the cooling water for cooling when the coolant level in the cooling pool is low.

[0024] Please see Figure 1-4A cooling device for PET monofilament manufacturing includes a main body 1, a cavity 12 inside the main body 1, a maintenance cover 2 hinged to the top of the main body 1 via a hinge 6, and passage openings 7 on both inner walls of the cavity 12 that communicate with the outside. Two transmission boxes 9 protrude from the cavity 12, and transmission chambers 20 are formed inside the transmission boxes 9. Two transmission sliders 15 are slidably installed in the transmission chambers 20. A transmission gear 17 is rotatably installed at the center of the transmission chambers 20. Both transmission sliders 15 have toothed grooves 19 that mesh with the transmission gear 17. A guide roller 23 connects every two transmission sliders 15 that are on the same horizontal plane. A servo motor 24 is installed on the main body 1, and the output shaft of the servo motor 24 is installed on one of the transmission gears 17. A cooling pool 11 is provided inside the cavity 12. A sponge block 22 is slidably installed on the maintenance cover 2. Two rectangular grooves 10 that are symmetrical to each other and adapted to the transmission sliders 15 are formed on the transmission boxes 9.

[0025] Through the coordinated arrangement of the transmission slider 15, transmission gear 17, and guide roller 23, PTE monofilaments can be passed through the two through-holes 7 and wound onto the two guide rollers 23 respectively. This allows the PET monofilaments to pass through the cooling pool 11 for cooling, and then be wiped and dried by the sponge block 22 and the blower mechanism 3, keeping the cooled PET monofilaments relatively dry. Furthermore, the servo motor 24 drives the transmission gear 17 to rotate, causing the two transmission sliders 15 to move away from each other. This facilitates the placement of the PET monofilaments onto the two guide rollers 23, and ensures that the PET monofilaments remain immersed in the cooling water for cooling even when the coolant level in the cooling pool 11 is low.

[0026] Specifically, in this embodiment, the cooling pool 11 is located directly below one of the guide rollers 23, and the sponge block 22 is located directly above the other guide roller 23 and abuts against the guide roller 23.

[0027] The PET monofilaments can be effectively cooled and dried by the provided cooling pool 11 and sponge block 22.

[0028] Specifically, in this embodiment, the inspection cover 2 is provided with a blower mechanism 3, the blower mechanism 3 is provided with multiple cooling fans 8, and the top of the blower mechanism 3 is fastened with a filter screen 4.

[0029] Specifically, in this embodiment, two symmetrical sliding rods 14 are slidably installed on the inspection cover 2, a sponge block 22 is installed at the bottom of the two sliding rods 14, the same connecting plate 5 is installed on the top of the two sliding rods 14, and a compression spring 21 is sleeved on each of the two sliding rods 14. One end of the compression spring 21 abuts against the inspection cover 2, and the other end of the compression spring 21 abuts against the sponge block 22.

[0030] With the provided slide bar 14 and compression spring 21, the elastic potential energy of the compression spring 21 can keep the sponge block 22 in a downward state and keep the sponge block 22 pressed against the surface of the guide roller 23 to dry the PET monofilament.

[0031] Specifically, in this embodiment, both guide rollers 23 are provided with multiple annular grooves 13 along the axial direction, which can separate multiple PET monofilaments and prevent them from getting tangled together.

[0032] Specifically, in this embodiment, two guide rods 18 are arranged in the transmission cavity 20, and two transmission sliders 15 in the transmission cavity 20 are provided with sliding holes 16 that are adapted to the guide rods 18. The movement direction of the transmission sliders 15 can be guided by the guide rods 18 and the sliding holes 16 on the transmission sliders 15.
