Description

Technical Field

[0001] This utility model relates to the technical field of heat setting of polyester filament, specifically a heat setting device for low-elasticity fine denier polyester filament. Background Technology

[0002] In the field of chemical fiber production, polyester filament is widely used in textiles, industry and high-performance materials due to its excellent mechanical properties, chemical resistance and processing adaptability. Among them, low-elasticity fine denier polyester filament (monofilament fineness ≤1.0 denier) is increasingly in demand in high-end textiles (such as medical dressings, ultra-thin sports fabrics) and special composite materials due to its softness, lightness and thinness and high-density weaving adaptability.

[0003] For example, CN202320242640.8 discloses a heat-setting device for polyester filaments with uniform heating, relating to the field of polyester filament heat-setting technology. The device includes a housing with sliding openings on both sides. Polyester filaments are slidably disposed within these openings. The housing contains a condensate removal mechanism, two guiding components, and a heating component. The condensate removal mechanism includes a baffle, a driving component, a water receiving tank, and a fixing pipe. The baffle is rotatably connected to the housing and connected to the driving component. The water receiving tank is located on one side of the housing. The two ends of the fixing pipe are respectively fixedly inserted into the water receiving tank and the housing. The driving component includes a mounting base, a fixing base, and a cylinder. The mounting base and the fixing base are respectively located on the top of the baffle and the top wall of the housing. This utility model provides a simple structure and convenient operation for the polyester filament heat-setting device. It not only ensures uniform heating of the polyester filaments but also prevents condensate droplets from dripping back onto the filaments.

[0004] The aforementioned patent can collect water droplets generated during the shaping of polyester filaments by tilting and dripping. However, it cannot guarantee that the water droplets will not drip onto the polyester filaments during the collection process. By tilting the baffle to make the water droplets slide into the water tank, there is still a possibility of water droplets dripping during the sliding process, which will still affect the shaping of the polyester filaments and result in poor treatment of the generated water droplets.

[0005] Therefore, we propose a heat-setting device for low-elasticity fine denier polyester filaments to solve the problems mentioned above. Utility Model Content

Example

[0034] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-8 The extrusion assembly 6 includes a drive motor 61 located at the top right of the fixed groove 5 and a turntable 62 fixedly installed at the output end of the drive motor 61. A fixed shaft 63 is fixedly installed on the left side of the turntable 62 near the top, and a sliding frame 64 is slidably sleeved on the outer side of the fixed shaft 63. Connecting rods 65 are fixedly installed on the bottom of the sliding frame 64 near the front and rear sides. A movable plate 66 is fixedly installed on the lower end of the connecting rods 65. Movable rods 67 are fixedly installed on the bottom of the movable plate 66 near the front and rear sides, and the lower ends of the movable rods 67 slide through and extend into the inner cavity of the fixed groove 5, and are fixedly installed on the extrusion plate 68. The extrusion plate 68 can be driven to move downward, thereby squeezing out the residual water on the wiping sponge 74 and avoiding excessive water affecting the wiping effect on the top plate 20.

[0035] A fixing bracket 611 is fixedly installed at the middle of the top of the drive motor 61, and the lower end of the fixing bracket 611 is fixedly installed on the fixing groove 5, which serves to support and fix the drive motor 61.

[0036] L-shaped plates 641 are fixedly installed on the top of the sliding frame 64 near the front and rear sides, and guide rods 642 are slidably installed through the L-shaped plates 641. The lower ends of the guide rods 642 are fixedly installed on the fixed grooves 5, which guide and limit the movement of the sliding frame 64, so that it moves up and down stably and has high stability.

[0037] In this embodiment: After wiping for a period of time, a lot of water will remain on the wiping sponge 74. When the threaded rod 72 moves and drives the wiping sponge 74 into the fixed groove 5, it can stop running. At this time, the drive motor 61 can be started. When the drive motor 61 runs, it will drive the turntable 62 to rotate. When the turntable 62 rotates, it will drive the sliding frame 64 to move up and down back and forth through the fixed shaft 63. When the sliding frame 64 moves up and down, it will drive the movable plate 66 to move up and down back and forth through the connecting rod 65. When the movable plate 66 moves up and down, it will drive the extrusion plate 68 to move up and down back and forth through the movable rod 67. This can squeeze out the water droplets adsorbed on the wiping sponge 74 and discharge them through the discharge port. After the extrusion is completed, the extrusion plate 68 can be restored, and then the wiping sponge 74 can continue to move left and right to wipe the water droplets on the top plate 20.
