Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a stretching and texturing device and process for bright flat polyester filaments. Background Technology

[0002] Polyester filament is an important synthetic fiber material, made from polyester into fine filaments with lengths of over a kilometer. False twist texturing equipment is a key piece of equipment in the textile industry used to produce elastic and textured yarns. This type of equipment uses specific processes to give polyester filaments the required elasticity, bulkiness, and other physical properties.

[0003] Referring to patent application CN112342653B, a texturing device for DTY bright ultra-soft flat yarn is disclosed. The frame has a false twisting mechanism, a feeding mechanism, a discharging mechanism, and a detection mechanism fixedly installed on its front side. The feeding mechanism is located on the left side of the frame, the discharging mechanism on the right side, the false twisting mechanism between the feeding and discharging mechanisms, and the detection mechanism above the discharging mechanism. The detection mechanism includes a detection column, which is I-shaped. A wire block is fixedly connected to the top and bottom of the front side of the detection column. An annular groove is cut into the bottom middle of the detection column, and a spiral ring is fitted inside. Through the detection mechanism, the elasticity of the twisted yarn is automatically detected during the twisting process. This has the advantage of not requiring machine stoppage for detection and allows for continuous detection of the twisted yarn during processing, automatically transmitting signals back to the system, thus improving detection and processing efficiency and the twisting effect.

[0004] However, in the above-mentioned technology, after prolonged operation of the false twisting device for flat polyester yarn, fiber debris easily accumulates on the outside of the false twisting roller. These fine fiber debris not only affect the operating efficiency and accuracy of the false twisting roller, but may also adversely affect the overall quality of the yarn. This necessitates regular cleaning of the false twisting roller. Existing devices typically clean the false twister with a brush and air blower after shutdown, a cumbersome and time-consuming process that reduces overall work efficiency and limits its practicality.

[0025] Beneficial effects

[0026] This invention provides a stretching and texturing device and process for bright flat polyester filaments.

[0027] Compared with existing technologies, it has the following advantages:

[0028] 1. This is a stretching and texturing equipment and process for bright flat polyester filaments. The equipment features a soft brush and an inner cylinder for easy cleaning of the false twist components. When cleaning is required, the drive motor is activated to rotate the driven gear ring, which in turn rotates the driven gear ring. The driven gear ring then drives the fixed cylinder to clean the fiber debris on the outside of the false twist roller through the soft brush and brush disc. At the same time, the air injected through the soft brush enters the inner cylinder and is ejected from the ventilation holes and ventilation slots, improving the efficiency of cleaning debris and dust. This method is convenient, quick, and improves the overall work efficiency.

[0029] 2. This is a stretching and texturing equipment and process for bright flat polyester filaments. The first screw and slider facilitate the separation and cleaning of the false twist rollers. In use, the DC motor is started to drive the first bevel gear shaft to rotate the first screw. Then, the first screw drives the movable cylinder to move the slider through the adjusting plate. At this time, the slider drives the false twister drive seat to separate the false twist rollers. After the DC motor is turned off and the position of the slider is fixed, the false twist rollers can be cleaned. This facilitates subsequent cleaning and makes it easy to observe the wear of the false twist rollers. It is practical.

[0030] 3. This stretching and texturing equipment and process for bright flat polyester filaments uses a fan and filter frame to collect flying dust and fiber debris. When the cleaning component cleans the false twist component, the fan will draw air outward. The suction generated by the fan will draw the dust inside the protective cover into the side box. The filter frame can filter out the fiber debris and dust for collection, preventing the fiber debris and dust from scattering everywhere and further reducing the difficulty of subsequent cleaning work.

[0055] The fan 248 and filter frame 249 can collect flying dust and fiber debris. When the cleaning component 23 cleans the false twist component 21, the fan 248 will draw air outward. At this time, the suction generated by the fan 248 will draw the dust inside the protective cover 246 into the side box 244. The filter frame 249 can filter out the fiber debris and dust for collection, preventing the fiber debris and dust from scattering everywhere and further reducing the difficulty of subsequent cleaning work.

[0056] This invention also discloses a stretching and texturing process for bright flat polyester filaments, specifically including the following steps:

[0057] Step 1: When using the device, install it in a suitable position through the rear plate 1 and connect the air inlet pipe 235 to the external air pump. Then, pass one end of the smooth flat polyester filament through the guide block on the front side of the movable plate 236 and the guide block on the front side of the base plate 3. Then, drive the three output shafts 215 to rotate through the false twister drive seat 211. Then, the three output shafts 215 will drive the insert block 2115 through the slot 2116 to rotate the pull rod 218. Then, the pull rod 218 will drive the clamping plate 2110 through the two clamping slots 217 to rotate the false twist roller 216 to perform false twisting processing on the smooth flat polyester filament.

[0058] Step 2: When the false twist assembly 21 needs to be cleaned after processing, press the clamping plate 2110 to squeeze it out of the lower clamping groove 217, and then pull the pull rod 218 to drive the connecting ring 2114 to pull the insert 2115 out of the slot 2116. At this time, the pull rod 218 will drive the clamping plate 2110 to the position of the upper clamping groove 217. Then, the elastic force of the first spring 219 will drive the clamping plate 2110 to be locked inside the upper clamping groove 217 to fix the position of the pull rod 218. Then, start the cylinder 232 to drive the horizontal plate 233 to move the movable plate 236 forward. Then, the movable plate 236 will drive the fixed cylinder 238 to move above the false twist assembly 21.

[0059] Step 3: Then, start the DC motor 221 to drive the first bevel gear shaft 222, causing the first screw 224 to rotate. The first screw 224 then drives the movable cylinder 223 to pull the slider 226 via the adjusting plate 225. At this time, the slider 226 drives the false twist drive seat 211, causing the false twist roller 216 to separate. Simultaneously, the DC motor 221 drives the first bevel gear shaft 222 to rotate, which in turn drives the double-headed bevel gear shaft 254 to rotate. The double-headed bevel gear shaft 254 then drives the second bevel gear shaft 255, causing the slot 258 to rotate and lowering the output shaft 215. Then, the second movable block 251 drives the fixed box 231. The movable plate 236 is lowered synchronously. At this time, the movable plate 236 will drive the fixed cylinder 238 to insert between the false twist rollers 216. Then, the DC motor 221 is turned off to fix the position of the movable plate 236. Then, the drive motor 234 is started to drive the drive gear 2310 to rotate the driven gear ring 2312. Then, the driven gear ring 2312 will drive the fixed cylinder 238 to clean the fiber debris on the outside of the false twist rollers 216 through the soft brush 237 and the brush plate 239. At the same time, the gas injected through the soft brush 237 will enter the inner cylinder 2318 and be sprayed out from the ventilation hole 2317 and the ventilation groove 2316 to improve the efficiency of cleaning debris and dust.

[0060] Step 4: When cleaning component 23 cleans false twist component 21, fan 248 will draw air outward. At this time, the suction generated by fan 248 will draw the dust inside protective cover 246 into side box 244. Then, the filter frame 249 can filter out fiber debris and dust, preventing fiber debris and dust from flying and affecting the working environment.
