Description

Technical Field

[0001] This utility model relates to the technical field of spinning cooling devices, specifically a spinning cooling device for producing high-stability, low-shrinkage polyester industrial yarn. Background Technology

[0002] A rapid cooling device for a spinning tunnel, disclosed in CN218580149U, includes a sleeve with sealing rings at both ends. The sealing rings are coaxially aligned with the sleeve and are sealed and fixedly connected to it. An inlet pipe and an outlet pipe are connected to the sleeve, arranged vertically. A stirring mechanism is installed inside the sleeve, located between the inlet and outlet pipes. This rapid cooling device for the spinning tunnel improves the cooling speed of the spinning process and the tunnel. Furthermore, the multi-angle stirring of the water during the cooling process further enhances the cooling speed. Additionally, water cooling prevents adjacent spinning fibers from easily sticking together and becoming tangled.

[0003] In the aforementioned rapid cooling device for a spinning tunnel, the rotation of the stirring assembly (first blade) and the auxiliary unit (second blade) relies entirely on water flow. When the water inflow is small, the water flow is slow, resulting in low rotation speeds for both the first and second blades and insufficient stirring force. This leads to uneven water temperature distribution within the casing and reduced heat dissipation efficiency. Conversely, when the water inflow is excessive, the high rotation speed may cause turbulent water flow, which in turn increases heat exchange resistance. Furthermore, impurities in the water may jam the blades, causing stirring failure. Utility Model Content

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this invention provides a spinning cooling device for producing high-stability, low-shrinkage polyester industrial yarn. It solves the problem of a rapid cooling device for spinning tunnels where the rotation of the stirring assembly (first blade) and auxiliary unit (second blade) relies entirely on water flow. When the water flow is small, the water speed is slow, resulting in low rotational speeds for both the first and second blades and insufficient stirring force, leading to uneven water temperature distribution within the casing and reduced heat dissipation efficiency. Conversely, when the water flow is excessive, the high rotational speed may cause turbulent water flow, increasing heat exchange resistance. Furthermore, impurities in the water may clog the blades, causing stirring failure.

[0005] Technical solution: To achieve the above objectives, this utility model provides the following technical solution: a spinning cooling device for producing high-stability, low-shrinkage polyester industrial yarn, including a support plate, a sleeve fixedly connected to the upper surface of the support plate, and circular grooves opened on the front and rear inner walls of the sleeve.

[0006] The cooling assembly is set on two circular slots and includes two circular sealing plates, which are respectively rotatably engaged in the inner walls of the two circular slots.

[0007] The two circular sealing plates are fixedly connected to the opposite sides of each other with a fixed sleeve. The inner walls of the two fixed sleeves are fixedly fitted with cooling pipes, and the outer walls of the cooling pipes are fixedly fitted with spiral heat dissipation plates. The spiral heat dissipation plates are located at the opposite sides of the two fixed sleeves.

[0008] Preferably, both ends of the cooling pipe rotatably extend through the outer surface of the sleeve, and both ends of the cooling pipe are rotatably connected to connecting pipes, with both connecting pipes communicating with the interior of the cooling pipe.

[0009] Preferably, a concave plate is fixedly connected to the upper surface of both connecting pipes, and both concave plates are fixedly connected to the upper surface of the sleeve.

[0010] Preferably, a servo motor is fixedly installed on the left side of the connecting pipe on the front side, the output end of the servo motor is fixedly connected to a connecting shaft, and the rear end of the connecting shaft is fixedly connected to a small gear.

[0012] Preferably, a water inlet pipe communicating with the interior is fixedly connected to the rear side of the upper surface of the sleeve, and a water outlet pipe communicating with the interior is fixedly connected to the front side of the right side of the sleeve.

[0013] Preferably, both the outlet pipe and the inlet pipe are equipped with a switch valve.

[0014] Beneficial effects: Compared with the prior art, this utility model provides a spinning cooling device for producing high-stability, low-shrinkage polyester industrial yarn, which has the following beneficial effects:

[0015] 1. This high-stability, low-shrinkage polyester industrial yarn spinning cooling device, through the stable output of the servo motor and the meshing transmission of the pinion and gear, keeps the cooling pipe and spiral heat dissipation plate at a uniform speed, avoiding uneven cooling caused by speed fluctuations, and ensuring that the polyester industrial yarn has high stability and low shrinkage after cooling.

[0016] 2. This high-stability, low-shrinkage polyester industrial yarn spinning cooling device features a spiral heat dissipation plate fixedly fitted to its outer wall that rotates along with the cooling pipe. The spiral structure increases the contact area with the cooling water inside the pipe, and the rotation agitates the cooling water, ensuring full contact between the cooling water and the spiral heat dissipation plate and the outer wall of the cooling pipe, thus accelerating heat exchange.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a new technical solution: a spinning cooling device for producing high-stability, low-shrinkage polyester industrial yarn, including a support plate 1, a sleeve 2 fixedly connected to the upper surface of the support plate 1, and circular grooves 14 opened on the front and rear inner walls of the sleeve 2, a cooling assembly, the cooling assembly is set on the two circular grooves 14, and the cooling assembly includes two circular sealing plates 12, the two circular sealing plates 12 are respectively rotatably engaged in the inner walls of the two circular grooves 14;

[0024] Among them, the two circular sealing plates 12 are fixedly connected to the opposite sides of the fixed sleeves 11, the inner walls of the two fixed sleeves 11 are fixedly fitted with cooling pipes 13, the outer walls of the cooling pipes 13 are fixedly fitted with spiral heat dissipation plates 10, and the spiral heat dissipation plates 10 are located at the opposite sides of the two fixed sleeves 11.

[0025] Furthermore, both ends of the cooling pipe 13 rotatably extend through the outer surface of the sleeve 2, and both ends of the cooling pipe 13 are rotatably connected to connecting pipes 6, with both connecting pipes 6 communicating with the interior of the cooling pipe 13.

[0026] Furthermore, concave plates 4 are fixedly connected to the upper surfaces of both connecting pipes 6, and both concave plates 4 are fixedly connected to the upper surface of the sleeve 2.

[0027] Furthermore, a servo motor 7 is fixedly installed on the left side of the front connecting pipe 6, and a connecting shaft is fixedly connected to the output end of the servo motor 7. A pinion 8 is fixedly connected to the rear end of the connecting shaft.

[0028] Furthermore, a large gear 5 is fixedly sleeved on the outer wall of the cooling pipe 13, and the large gear 5 meshes with the small gear 8.

[0029] Furthermore, a water inlet pipe 3 communicating with the interior is fixedly connected to the rear side of the upper surface of the sleeve 2, and a water outlet pipe 9 communicating with the interior is fixedly connected to the front side of the right side of the sleeve 2.

[0030] Furthermore, both the outlet pipe 9 and the inlet pipe 3 are equipped with switch valves.

[0031] Furthermore, when using this high-stability, low-shrinkage polyester industrial yarn spinning cooling device, first connect the external water inlet pipe to the water inlet pipe 3, and then connect the external water outlet pipe to the water outlet pipe 9.

[0032] Then, the polyester industrial yarn is passed through the inner wall of the cooling pipe 13 through two connecting pipes 6, and then cooling water is injected into the inside of the sleeve 2. Then the servo motor 7 is started. The output end of the servo motor 7 drives the connecting shaft to rotate, and the connecting shaft drives the pinion 8 to rotate synchronously.

[0033] Among them, since the small gear 8 meshes with the large gear 5 on the outer wall of the cooling pipe 13, the rotation of the small gear 8 will drive the large gear 5 to rotate, and the large gear 5 will in turn drive the cooling pipe 13 to rotate under the support of the two circular sealing plates 12 (the circular sealing plates 12 are rotated and locked in the circular groove 14 of the sleeve 2, which ensures that the cooling pipe 13 can rotate flexibly and prevents the cooling water in the sleeve 2 from leaking).

[0034] When the cooling pipe 13 rotates, the spiral heat dissipation plate 10 fixedly sleeved on its outer wall will rotate together. The spiral structure increases the contact area with the cooling water in the sleeve 2, and the rotation can agitate the cooling water, so that the cooling water can fully contact the spiral heat dissipation plate 10 and the outer wall of the cooling pipe 13, accelerating heat exchange. The polyester industrial yarn on the inner wall of the cooling pipe 13 carries heat during the production process. The heat is transferred to the spiral heat dissipation plate 10 through the pipe wall of the cooling pipe 13, and then transferred to the cooling water in the sleeve 2 by the spiral heat dissipation plate 10, so as to achieve rapid cooling of the polyester industrial yarn.

[0035] The external water inlet pipe continuously injects low-temperature cooling water into the sleeve 2 through the water inlet pipe 3. The cooling water that has absorbed heat is discharged through the water outlet pipe 9 (the water flow rate can be adjusted by the switch valve to control the cooling efficiency), forming a cooling water circulation to ensure that the sleeve 2 always maintains a low temperature and ensures a stable cooling effect.

[0036] Among them, the two connecting pipes 6 are fixed on the sleeve 2 by the concave plate 4 and are rotatably connected to the cooling pipe 13. This does not affect the rotation of the cooling pipe 13, and ensures that the polyester industrial yarn maintains a stable path when passing through the cooling pipe 13, avoiding yarn deviation or wear due to the rotation of the cooling pipe.

[0037] The stable output of the servo motor 7 and the meshing transmission between the pinion 8 and the gear 5 ensure that the cooling pipe 13 and the spiral heat sink 10 maintain a uniform rotation speed, avoiding uneven cooling caused by speed fluctuations and ensuring that the polyester industrial yarn has high stability and low shrinkage after cooling.
