Description

Technical Field

[0001] This utility model relates to the field of polyester elastic yarn production technology, specifically to a cooling and shaping device for low-elasticity polyester yarn. Background Technology

[0002] Polyester low-elasticity yarn is a type of textured yarn from polyester chemical fiber. Cooling and setting devices are required during the production of polyester low-elasticity yarn. A search revealed a patent with authorization announcement number CN218321809U, entitled "A Cooling Device for Processing Polyester Low-Elasticity Yarn," which includes a processing box, a transport mechanism (including a servo motor), two transport rollers rotatably connected to both ends of the processing box's inner cavity, the servo motor mounted on one side of the processing box, and its output connected to one of the transport rollers via a coupling; a water cooling mechanism including a water tank and a drain pipe, the water tank located inside the processing box; and a drying mechanism including a drying fan and an exhaust pipe, the drying fan bolted to the upper end of the processing box. This cooling device for processing polyester low-elasticity yarn can perform water cooling processing on polyester low-elasticity yarn, making cooling more uniform, increasing the cooling effect, and allowing for water recycling, thus saving resources and being environmentally friendly. However, in actual use, the cooling device for processing polyester low-elasticity yarn did not filter the air entering the drying fan, and the air discharged from the drying fan contained dust, which easily contaminated the polyester low-elasticity yarn. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a cooling and shaping device for polyester low-elasticity yarn.

[0004] The technical solution adopted by this utility model to solve its technical problem is a polyester low-elasticity yarn cooling and shaping device, including a box body. Both sides of the box body have notches. A cover plate is fixed to the top of the box body. A housing and a fan are fixed to the top of the cover plate. A U-shaped main pipe is fixed to the air inlet pipe of the fan. A first valve is fixed to one end of the main pipe, and a second valve is fixed to the other end. Both the first and second valves extend into the housing body. Two air inlets are provided on the side of the housing body away from the fan. A partition is fixed inside the housing body. A first filter and a second filter are provided on both sides of the partition. Two slots for the first filter and two slots for the second filter are provided on the inner bottom wall of the housing body. The box has a matching slot, and the tops of the two first and second filters both penetrate the top of the box. A duct is fixed to the exhaust pipe of the fan, and the bottom end of the duct penetrates the cover plate and is fixed to a horizontal pipe. Multiple nozzles are fixed to the bottom end of the horizontal pipe. A coolant tank and a water pump are provided on one side of the box. The water pump is fixed to the top of the coolant tank. A bend is fixed to the water pump's inlet pipe, and the bottom end of the bend extends into the coolant tank. A connecting pipe is fixed to the water pump's drain pipe, and the end of the connecting pipe away from the water pump extends into the box and is fixed to a cooling pipe. A branch pipe is fixed to the end of the cooling pipe away from the connecting pipe, and the bottom end of the branch pipe extends into the coolant tank. An exhaust port is provided on the side of the box away from the water pump, and a protective net is provided inside the exhaust port.

[0005] By adopting the above technical solution, the first valve is opened and the second valve is closed. The polyester low-elasticity yarn that needs to be cooled is inserted through the notch on one side of the box. The water pump draws coolant from the coolant tank, and the coolant enters the cooling pipe through the connecting pipe. The polyester low-elasticity yarn comes into contact with the cooling pipe, and the coolant in the cooling pipe absorbs heat, achieving initial cooling of the polyester low-elasticity yarn. The fan runs, and air enters the box. The first and second filters near the first valve filter the dust in the air. The filtered air is sprayed downwards onto the polyester low-elasticity yarn through the duct and horizontal pipe and multiple nozzles to cool the polyester low-elasticity yarn. This not only prevents dust from contaminating the polyester low-elasticity yarn, but also improves the cooling effect. The branch pipe setting facilitates the circulation of coolant. When it is necessary to clean or replace the first and second filters near the first valve, the first valve is closed and the second valve is opened. The first and second filters near the second valve are used to filter the dust in the air without affecting the cooling operation.

[0006] Specifically, the top of the box is fixed with four blocks, and the top of the box is provided with four locking bolts. Each block is provided with a screw hole that matches the locking bolt.

[0007] By adopting the above technical solution and setting the locking bolt, the stability of the first and second filters can be improved. Loosening the locking bolt and lifting the first and second filters allows them to be removed for cleaning or replacement.

[0008] Specifically, the top of the coolant tank is provided with a filling port, and a protective cover is provided inside the filling port.

[0009] By adopting the above technical solution, the design of the filling port facilitates the addition of coolant to the coolant tank, and the protective cover prevents debris from falling into the coolant tank.

[0010] Specifically, the coolant tank has multiple through slots on both sides, each through slot has a heat-conducting plate, and each heat-conducting plate is connected to the coolant tank.

[0011] By adopting the above technical solution, the heat-conducting plate is designed to facilitate the cooling of the coolant in the coolant tank.

[0012] Specifically, support legs are fixed at the four corners of the bottom of the box.

[0013] The beneficial effects of this utility model are:

[0014] (1) The polyester low-elasticity yarn cooling and shaping device of this utility model opens the first valve and closes the second valve. The polyester low-elasticity yarn that needs to be cooled is inserted through the notch on one side of the box. The water pump draws the coolant from the coolant tank. The coolant enters the cooling pipe through the connecting pipe. The polyester low-elasticity yarn comes into contact with the cooling pipe. The coolant in the cooling pipe absorbs heat, realizing the initial cooling of the polyester low-elasticity yarn. The fan runs and air enters the box. The first and second filters near the first valve filter the dust in the air. The filtered air is sprayed down onto the polyester low-elasticity yarn through the duct and horizontal pipe and multiple nozzles to cool the polyester low-elasticity yarn. This not only prevents dust from contaminating the polyester low-elasticity yarn, but also improves the cooling effect. The branch pipe setting facilitates the circulation of coolant. When it is necessary to clean or replace the first and second filters near the first valve, close the first valve and open the second valve. Use the first and second filters near the second valve to filter the dust in the air without affecting the cooling operation.

[0015] (2) The polyester low elastic yarn cooling and shaping device of this utility model has a locking bolt that can improve the stability of the first filter screen and the second filter screen. By loosening the locking bolt and lifting the first filter screen and the second filter screen, the first filter screen and the second filter screen can be taken out for cleaning or replacement.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To prevent dust from contaminating the polyester low-elasticity yarn, as one embodiment of this utility model, such as Figures 1 to 5As shown, the polyester low-elasticity yarn cooling and shaping device of this utility model includes a box body 1. Both sides of the box body 1 have notches. A cover plate 2 is bolted to the top of the box body 1. A box body 3 and a fan 4 are bolted to the top of the cover plate 2. A U-shaped main pipe 40 is welded to the air inlet pipe of the fan 4. A first valve 41 is welded to one end of the main pipe 40, and a second valve 42 is welded to the other end of the main pipe 40. Both the first valve 41 and the second valve 42 extend into the box body 3. Two air inlets are provided on the side of the box body 3 away from the fan 4. A partition plate 30 is welded to the inside of the box body 3. A first filter screen 12 and a second filter screen 13 are provided on both sides of the partition plate 30. Two slots for the first filter screen 12 and two slots for the second filter screen 13 are provided on the inner bottom wall of the box body 3. The aperture of the first filter screen 12 is larger than the aperture of the second filter screen 13. The top ends of the first filter screen 12 and the second filter screen 13 both penetrate the top end of the box body 3. A duct 5 is welded and fixed to the exhaust pipe of the fan 4. The bottom end of the duct 5 penetrates the cover plate 2 and is welded and fixed to a horizontal pipe 50. Multiple nozzles 51 are welded and fixed to the bottom end of the horizontal pipe 50. A coolant tank 6 and a water pump 7 are provided on one side of the box body 1. The water pump 7 is fixed to the top of the coolant tank 6 by bolts. A bend 9 is welded and fixed to the inlet pipe of the water pump 7. The bottom end of the bend 9 extends into the coolant tank 6. A connecting pipe 8 is welded and fixed to the drain pipe of the water pump 7. The end of the connecting pipe 8 away from the water pump 7 extends into the box body 1 and is welded and fixed to a cooling pipe 80. A branch pipe 11 is welded and fixed to the end of the cooling pipe 80 away from the connecting pipe 8. The bottom end of the branch pipe 11 extends into the coolant tank 6. An exhaust port is provided on the side of the box body 1 away from the water pump 7. A protective net (existing technology, not shown) is provided inside the exhaust port. The protective net is connected to the box body 1 by bolts.

[0025] In use, open the first valve 41 and close the second valve 42. Insert the polyester low-elasticity yarn that needs to be cooled through the notch on one side of the housing 1. The water pump 7 draws coolant from the coolant tank 6. The coolant enters the cooling pipe 80 through the connecting pipe 8. The polyester low-elasticity yarn comes into contact with the cooling pipe 80, and the coolant in the cooling pipe 80 absorbs heat, achieving initial cooling of the polyester low-elasticity yarn. The fan 4 operates, and air enters the housing 3. The first filter screen 12 and the second filter screen 13 near the first valve 41 filter the dust in the air. The filtered air passes through the duct 5 and the horizontal pipe 50 and is sprayed downwards from multiple nozzles 51. The polyester low-elasticity yarn exits from the nozzles 51. When passing below, the polyester low-elasticity yarn is cooled, which not only prevents dust from contaminating the polyester low-elasticity yarn, but also improves the cooling effect. The setting of branch pipe 11 facilitates the circulation of coolant. When it is necessary to clean or replace the first filter screen 12 and the second filter screen 13 near the first valve 41, close the first valve 41 and open the second valve 42. Use the first filter screen 12 and the second filter screen 13 near the second valve 42 to filter the dust in the air without affecting the cooling operation. Lift the first filter screen 12 and the second filter screen 13 near the first valve 41 to remove the first filter screen 12 and the second filter screen 13 for cleaning or replacement.

[0026] To improve the stability of the first filter 12 and the second filter 13, for example, such as Figure 3 As shown, four blocks 31 are welded and fixed to the top of the box body 3, and four locking bolts 32 are provided on the top of the box body 3. Each block 31 is provided with a screw hole that matches the locking bolt 32. Tightening the locking bolts 32 close to the first filter screen 12 and the second filter screen 13 will make the ends of the locking bolts 32 fit tightly against the first filter screen 12 and the second filter screen 13, thereby improving the stability of the first filter screen 12 and the second filter screen 13.

[0027] For ease of adding coolant, for example, such as Figure 1 As shown, the top of the coolant tank 6 is provided with a filling port, and a protective cover is provided inside the filling port.

[0028] To facilitate the cooling of the coolant in the coolant tank 6, for example, such as... Figure 1 As shown, the coolant tank 6 has multiple through slots on both sides, and each through slot has a heat-conducting plate 10. Each heat-conducting plate 10 is welded to the coolant tank 6.

[0029] Support legs are welded and fixed at the four corners of the bottom of the box 1.

[0030] In use, the first valve 41 is opened and the second valve 42 is closed. The polyester low-elastic yarn that needs to be cooled is inserted through the notch on one side of the housing 1 and exited through the notch on the other side of the housing 1 and connected to the external traction mechanism or winding mechanism (existing technology). The water pump 7 draws coolant from the coolant tank 6. The coolant enters the cooling pipe 80 through the connecting pipe 8. The polyester low-elastic yarn comes into contact with the cooling pipe 80. The coolant in the cooling pipe 80 absorbs heat, achieving initial cooling of the polyester low-elastic yarn. The fan 4 operates, and air enters the housing 3. The first filter screen 12 and the second filter screen 13 near the first valve 41 filter the dust in the air. The filtered air passes through the duct 5 and the horizontal pipe 50 and is sprayed downward from multiple nozzles 51. When the polyester low-elastic yarn passes under the nozzles 51, it is cooled down. This not only prevents dust from contaminating the polyester low-elastic yarn but also improves the cooling effect.

[0031] The branch pipe 11 facilitates the circulation of coolant. When it is necessary to clean or replace the first filter 12 and the second filter 13 near the first valve 41, close the first valve 41 and open the second valve 42. Use the first filter 12 and the second filter 13 near the second valve 42 to filter dust in the air without affecting the cooling operation. Loosen the locking bolt 32 and lift the first filter 12 and the second filter 13 near the first valve 41 to remove the first filter 12 and the second filter 13 for cleaning or replacement.
