Description

Technical Field

[0001] The utility model relates to the technical field of polyester spinning equipment, in particular to a polyester spinning device with a special-shaped cross-section. Background Art

[0002] In the production process of fine-denier special-shaped polyester filaments, a corresponding spinning box is required to melt and spray the fine-denier special-shaped polyester materials, and this spinning box requires a corresponding spiral cooling component to promote spinning and forming; Patent No. CN202320911104.2 discloses a spiral cooling component for a fine-denier special-shaped polyester filament spinning box. By arranging an air cooler and a filter tank in the device, during the spinning process, the motor drives the cylinder and the spiral ring to rotate through the gear ring assembly, and the air cooler injects the cold air into the spiral ring through the branch pipe, the ventilation ring, and the ventilation groove. The vacuum pump passes through the filter tank, A conduit, cooling element, vacuum ring, and filter ring extract air from the periphery of the spinneret. The gas passing through the rotating spiral ring is converted into cold air through heat exchange. As the cold air contacts the molten yarn, the molten yarn is cooled and formed. The gas produced by the spinneret is then introduced into a filter tank along with the cold air, where the activated carbon mesh inside the filter adsorbs toxic substances. However, because the vacuum pump extracts exhaust gas from the periphery of the spinning equipment spinneret through a pipe, the suction generated by the vacuum pump directly affects the surface of the polyester yarn, which can affect the fine, partially hardened polyester yarn. To address this issue, we propose a spinning device for polyester with a special-shaped cross-section. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a polyester spinning device with a special-shaped cross-section.

[0005] A coil tube is installed on one side of the outer tank near the open end, and a suction nozzle is installed on the inner circumference of the coil tube, and there are multiple groups of suction nozzles. An air pump is installed on the outer wall surface of the spinning machine body, and a filter is installed on the suction end of the air pump, and a branch pipe for diversion is installed between the filter and the coil tube;

[0006] A vertical cylinder is installed between the branch pipe and the outer tank, and a valve located on the surface of the outer tank is installed between the vertical cylinder and the ring pipe;

[0007] The inner circumference of the vertical cylinder is equipped with a spiral tube, and a guide tube is installed between the spiral tube and the curved tube;

[0008] A tube sleeve located at the periphery of the spinneret is installed between the outer tank and the spinning machine body;

[0009] The coil tube is located at a side of the outer tank away from the spinneret.

[0010] By adopting the above technical solution, when the spinning equipment is used to produce polyester yarn with a special cross-section, the spinneret is convenient for spinning the polyester yarn with a special cross-section, and then the air cooler on the surface of the outer tank is operated to generate cold air, and then the cold air can be guided by the bent pipe and sprayed into the cavity between the outer tank and the cylinder through the nozzle. Then, when the cylinder rotates, the cold air can conveniently pass through the multiple groups of air holes on the outer periphery of the cylinder and contact the polyester yarn, so as to cool it and solidify it into shape. In addition, the continuously rotating cylinder can reduce the impact of the cold air blowing directly on the spinning.

[0011] When the special-section polyester yarn is cooled by the cold air inside the cylinder, it is convenient to be discharged from the opening on the other side of the cylinder. At this time, the vacuum pump on the top of the spinning machine body is convenient to provide suction to the coil tube in the outer tank through the branch pipe, and the gas discharged from the cylinder will pass through the coil tube. At this time, the suction in the coil tube is convenient to extract the gas discharged from the cylinder through the suction nozzle, so that the gas can be guided by the branch pipe and enter the filter for filtration before being discharged. At this time, the yarn has been hardened after cooling, and the suction force generated by the vacuum pump will not affect it, and it is convenient to smoothly extract the gas discharged from the cylinder.

[0012] The valve is convenient for controlling opening and closing, while the vertical tube is convenient for diverting the flow between the straight pipe and the coil pipe, so that the coil pipe can obtain smooth suction force;

[0013] The cold air generated by the air cooler is conveniently guided by the conduit into the spiral tube in the vertical cylinder, and the spiral tube is convenient for volatilizing the cold air into the vertical cylinder. At this time, the gas sucked into the vertical cylinder can exchange heat with the cold air in the spiral tube, which is convenient for cooling the gas and reducing the impact caused by the heat carried in the gas;

[0014] The tube sleeve is convenient for protecting the space between the spinneret and the outer tank, so that garbage and debris will not enter between the outer tank and the spinneret;

[0015] The coil tube is located at the opening of the cylinder in the outer tank, and the spinneret and the cylinder are connected to each other, so that the gas ejected by the spinneret can only be discharged from the opening at one end of the cylinder, and can conveniently pass through the coil tube near the opening end in the outer tank, so that the suction force inside the coil tube can stably extract the exhaust gas, making it easier to treat it.
