Description

Technical Field

[0001] This utility model belongs to the field of polyester fiber processing technology, and in particular relates to a shaping device for processing polyester fiber fabrics. Background Technology

[0002] Polyester fiber, as a commonly used synthetic fiber, has the characteristics of high strength, excellent abrasion resistance, and resistance to deformation. It is widely used in textiles, clothing, home textiles and other fields. In the polyester fiber processing process, the fibers after spinning and stretching need to be set to stabilize the molecular structure, improve dimensional stability and mechanical properties, and avoid shrinkage or shape change during subsequent use. The setting device for polyester fiber processing is the core equipment to achieve this step. It uses the principle of heat setting to cause the macromolecules inside the fiber to rearrange and fix, ensuring that the final polyester fiber product meets the requirements of production process and performance. It is a key processing equipment that connects the semi-finished and finished polyester fibers.

[0003] However, existing setting devices are not convenient for adjusting the tension of polyester fiber fabrics during use, which can lead to localized looseness or excessive tightness of the fabric during setting. Loose areas will produce wrinkles, which will become permanent defects after high-temperature setting; excessive tightness will cause fiber deformation, resulting in poor dimensional stability of the fabric after setting. Garments made from this fabric are prone to shrinkage and wrinkling, which not only affects product quality and increases the defect rate, but also reduces the durability of the fabric and shortens its service life. Utility Model Content

[0004] The purpose of this invention is to provide a setting device for processing polyester fiber fabrics. By setting a tension adjustment part, it solves the problem that existing setting devices are not convenient for adjusting the tension of polyester fiber fabrics during use, which leads to localized looseness or excessive tightness of the fabric during setting. Loose areas will produce wrinkles, which will form permanent defects after high-temperature setting; excessive tightness will cause fiber deformation, poor dimensional stability of the fabric after setting, and the finished garments will easily shrink and wrinkle, which will not only affect product quality and increase the defect rate, but also reduce the durability of the fabric and shorten its service life.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a shaping device for processing polyester fiber fabric, comprising a base plate, and further comprising: a shaping part disposed on the top of the base plate; a tension adjusting part disposed on the top of the base plate; and a cleaning part disposed above the base plate. The tension adjusting part comprises a sliding component and a guiding component. Two sliding components are provided, both of which are located above the base plate and are arranged opposite to each other. The guiding component is located above the base plate and between the two sliding components. The sliding component comprises a bracket fixedly connected to the top of the base plate. A rotating block is rotatably connected to the bracket. Two limiting blocks are fixedly connected to the bracket. An arc-shaped rod is fixedly connected between the two limiting blocks. The arc-shaped rod passes through the rotating block. The outer wall of the arc-shaped rod is slidably connected to the rotating block. A spring is sleeved on the outer wall of the arc-shaped rod. The bottom of the spring is fixedly connected to the rotating block, and the top of the spring is fixedly connected to the upper limiting block. The bend of the arc-shaped rod faces downward to the right.

[0007] Furthermore, the guiding assembly includes two limiting grooves respectively opened on two supports, each of which penetrates through the two supports. A connecting block is provided on the inner wall of each limiting groove, and the outer walls of the connecting blocks are rotatably connected to two rotating blocks. A guide member is provided between the two connecting blocks. The two limiting grooves and the two connecting blocks are mirror images of each other, and both limiting grooves are arc-shaped. The guide member includes a positioning roller rotatably connected between the two connecting blocks. Several guide rollers are rotatably connected between the inner walls of the two supports. Three guide rollers are provided, one at the top and two at the bottom. The bottom surfaces of the two lower guide rollers are kept on the same horizontal plane as the center lines of the two openings to prevent the fabric from contacting the side walls of the two openings. With the guiding action of the positioning roller and the multiple guide rollers, the fabric is guided to be conveyed along a predetermined path, ensuring stable movement of the fabric during processing.

[0008] Furthermore, the shaping part includes a heating box fixedly connected to the top of the base plate. The heating box contains fabric, and the inner wall of the heating box has two openings that penetrate the heating box. The inner wall of the heating box is hinged with two doors, and the two openings and the two doors are mirror images of each other.

[0009] Furthermore, the cleaning unit includes a rolling assembly and a hair-absorbing assembly, the rolling assembly being located on the right side of the heating chamber, and the hair-absorbing assembly being located on the right side of the heating chamber.

[0010] Furthermore, the rolling assembly includes two brackets two fixedly connected to the front top of the base plate, and two brackets three fixedly connected to the front and rear sides of the top of the base plate. Two cleaning rollers are rotatably connected to the inner walls of the two brackets three, and both cleaning rollers pass through the two brackets three. A power component is mounted on each of the two brackets two. The two brackets two are located on one side of the fabric and are mirror images of each other. The two brackets three are located on both sides of the fabric and are mirror images of each other. The two cleaning rollers are mirror images of each other, and both cleaning rollers are hollow rods. The power component includes a rotating shaft rotatably connected to the inner wall of the bracket two closest to the fabric, and a shaft rotatably connected to the inner wall of the bracket two furthest from the fabric. A motor is fixedly connected to the inner wall of the second bracket. The output shaft of the motor is fixedly connected to the rotating shaft via a coupling. Three gears are provided on the third bracket located on the front side of the top of the base plate. The two gears on the left are fixedly connected to the two cleaning rollers respectively. The inner wall of the gear on the right is fixedly connected to the rotating shaft. The two gears on the two cleaning rollers mesh with each other. The gear on the lower cleaning roller meshes with the gear on the rotating shaft. Driven by the motor and gears, the two cleaning rollers rotate relative to each other. The soft brush on their outer wall sweeps the surface of the fabric to remove dust, lint, etc.

[0011] Furthermore, the lint-collecting assembly includes two brackets four fixedly connected to the front and rear sides of the base plate. Both brackets four are located outside the two brackets three. A three-way pipe is fixedly connected to the inner wall of the front bracket four. Two suction pipes are connected to the rear side of the three-way pipe. The rear ends of the two suction pipes are fixedly connected to the rear bracket four.

Several soft brushes are fixedly connected to the outer wall of the cleaning roller. The soft brushes are circumferentially distributed, and there are gaps between each soft brush. Each gap extends into the cleaning roller. Through the suction grooves on the suction pipe, the lint and impurities swept out by the cleaning roller are sucked in and collected by the exhaust fan, preventing impurities from re-adhering to the fabric and improving the cleaning effect.

[0012] Furthermore, the spring is made of 17-7PH stainless steel, which has no decrease in elastic modulus below 200℃, and has strong oxidation resistance, and is free from rust and softening.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a tension adjustment unit, when the fabric is pulled, it squeezes the positioning roller, causing the connecting block to move in the limiting groove. The rotating block slides along the arc rod and stretches the spring, increasing the tension. The spring is stretched further, and the positioning roller moves down, shortening the length of the fabric in the heating box to buffer the tension. When the tension decreases, the spring force drives the rotating block to slide, and the positioning roller moves up, increasing the length of the fabric in the heating box to neutralize the tension. This allows the fabric length in the device to be adjusted to adapt to changes in the fabric tension, neutralizing the impact of tension changes. This can prevent fabric defects, ensure product quality, reduce the defect rate, and thus ensure the durability of the fabric and extend its service life.

[0015] 2. By setting up a cleaning section, the motor drives the rotating shaft to rotate, and the two cleaning rollers rotate in opposite directions through gear transmission. The soft brush sweeps away impurities from the fabric. At the same time, the exhaust fan generates suction through the three-way pipe, and the swept-out hair enters the suction pipe through the suction channel and is finally discharged from the device through the three-way pipe. This can clean the fabric before it enters the heating box, sweeping away impurities on its surface and preventing them from affecting the stability of subsequent production, thereby ensuring the stable operation of the device.

[0038] By setting up the cleaning section 3, the fabric 103 can be cleaned before entering the heating box 102, and impurities on its surface can be swept off to avoid affecting the stability of subsequent production, thereby ensuring the stable operation of the device.

[0039] It should be noted that the control of the heating box 102 and the motor 315 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0040] A specific application of this embodiment is as follows: In use, the two doors 105 can be opened, and then the cloth 103 can be passed between the two cleaning rollers 313, through the opening 104 on the right, then around the bottom of the guide roller 224 on the right, then around the top of the positioning roller 223, then around the left side of the upper guide roller 224 and the right side of the lower guide roller 224 respectively, and finally through the opening 104 on the left. The cloth 103 should be kept to pass through the middle area of ​​each of the two openings 104, avoiding contact between the cloth 103 and the inner walls of the two openings 104. Simultaneously, the cloth 103 is pulled to generate a certain tension, which squeezes the positioning roller 223, causing it to move the connecting block 222 within the limiting groove 221. At this time, the rotating block 212 slides on the arc-shaped rod 214, stretching the spring 215 and generating elastic force. Then, the cloth is pulled from the right side of the base plate 101 to the left side of the base plate 101, with the cloth 103 passing between the two cleaning rollers 313. When passing through, the motor 315 can be started, causing its output shaft to drive the right gear 316 to rotate via the rotating shaft 314, thereby driving the two gears 316 on the left to rotate. The two gears 316 on the left rotate in opposite directions. When the two gears 316 on the left rotate, they will drive the two cleaning rollers 313 to rotate, thereby driving several soft brushes 325 to rotate, cleaning the fabric 103. At the same time, the three-way pipe 322 can be ventilated. At this time, the three-way pipe 322 will drive the air in the two suction pipes 323 to flow towards the three-way pipe 322. The hair swept off by the soft brushes 325 will be drawn into the suction groove 324 by the wind and discharged from the device through the three-way pipe 322. After preparation, the two box doors 105 can be closed and the heating box 102 can be started, so that the heating wire inside can be heated and high-temperature steam can be injected through the jet nozzle set in the heating box 102. When the temperature is reached, the fabric 103 will be shaped under the pressure of several guide rollers 224. During the high-temperature setting process, when the tension of the fabric 103 increases, the spring 215 will be further stretched and generate greater elastic force. At this time, the positioning roller 223 will move downward. When the positioning roller 223 moves downward, the length of the fabric 103 in the heating box 102 will decrease, thereby providing a buffer for the tension generated by the fabric 103. When the tension of the fabric 103 decreases, under the action of the elastic force of the spring 215, the rotating block 212 will slide on the arc rod 214. Thus, under the action of the limiting groove 221, the positioning roller 223 will be moved upward through the connecting block 222. At this time, under the action of the positioning roller 223, the length of the fabric 103 in the heating box 102 will increase, thereby neutralizing the reduced tension.
