Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a novel air-jet spinning drawing and drafting assembly. Background Technology

[0002] Air-jet spinning is a new type of spinning technology that uses airflow to condense and twist fibers in a high-speed rotating spinning cup to produce yarn. It includes multiple components such as carding rollers, spinning cups, and false twisting devices. Cotton yarn production mainly involves four processes: opening, carding, drawing, and roving. Among them, the drawing process fully mixes fibers of different properties, such as chemical fibers and cotton. After drawing, the cotton sliver can be stretched into cotton fibers with higher strength and finer width by the drafting mechanism. The drafting mechanism is divided into two main categories according to its form: roller drafting drawing frame and carding machine.

[0003] For example, Chinese Patent Publication No. CN216550882U discloses an air-jet spinning drawing and drafting mechanism, including a guard plate. The inner side of the guard plate is provided with a base plate, a transfer box, an upper roller, and a lower roller. The aforementioned disclosure ensures the cleanliness of the rollers by continuously cleaning the cotton lint adhering to them during the drafting operation and collecting and processing the cleaned lint. However, this patent is not conducive to the quick installation and disassembly of the upper and lower rollers, and the cleaning effect on the cotton lint on the lower roller is poor, resulting in limited applicability and hindering long-term use and promotion. Therefore, those skilled in the art have provided a novel air-jet spinning drawing and drafting assembly to solve the problems mentioned in the background art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5This utility model provides a novel air-jet spinning drawing assembly technical solution: It includes two sets of support plates 1. A transfer box 101 and a collection box 102 are fixedly installed at the front and rear ends of the bottom of the corresponding outer wall of the two sets of support plates 1. A guide plate 103 and a guide seat 104 are fixedly installed at the front and rear ends of the outer top surface of the transfer box 101. A guide strip hole is also connected through the outer top surface of the guide plate 103. Multiple upper rollers 105 and lower rollers 106 are provided at the top and bottom ends of the corresponding outer wall of the two sets of support plates 1, located above the collection box 102. A replacement assembly 2 for quickly installing and removing the upper rollers 105 and lower rollers 106 is provided on the outer wall of one set of support plates 1. The replacement assembly 2 includes a through-type groove 201 opened on the outer wall of one set of support plates 1, corresponding to the upper rollers 105 and lower rollers 106. The two sets of grooves 201... The inner sliding plate 1 has a slider 202, and the two sliders 202 are respectively rotatably installed with a fixing sleeve 203 corresponding to the upper roller 105 and the lower roller 106. At the same time, the upper and lower ends of the inner side wall of another set of support plates 1 are respectively rotatably installed with a fixing sleeve 204 corresponding to the upper roller 105 and the lower roller 106. The outer peripheral surfaces of multiple upper rollers 105 and lower rollers 106 are respectively slidably inserted into the inner side of the fixing sleeve 203 and the fixing sleeve 204. The outer top surface of one set of support plates 1 fixes the two sliders 202 into the two slide grooves 201 at the same time by positioning screw 205. The inner peripheral surfaces of several fixing sleeves 203 are fixedly connected to multiple upper rollers 105 and lower rollers 106 by positioning screw 206. The outer side walls of the two sliders 202 are respectively fixedly installed with handle 207 and handle 208. First, the cotton strip is output from the guide hole on the guide plate 103, squeezed along the guide seat 104, and stretched between the lower roller 106 and the upper roller 105. When replacing or maintaining the lower roller 106 and the upper roller 105, first turn the positioning screw 1 205 to release the fixed relationship of the slider 202. Then, hold the handle 1 207 and the handle 2 208 in sequence to pull the slider 202 to separate it from the slide groove 201. At the same time, let one end of the multiple upper rollers 105 and lower rollers 106 detach from the inside of the fixing sleeve 2 204 and take it out from the inside of the slide groove 201. Then turn and take out the positioning screw 2 206 to let the other end of the multiple upper rollers 105 and lower rollers 106 detach from the inside of the fixing sleeve 1 203, so as to maintain and replace them. The operation is simple and convenient. At the same time, the reverse operation can quickly reinstall them, improving work efficiency.

[0026] Another set of support plates 1 has a cleaning assembly 3 on its outer wall for cleaning lint from the lower rollers 106. The cleaning assembly 3 includes rotating shafts 301 that are rotatably mounted on the inner walls of the two sets of support plates 1 and located directly below the multiple lower rollers 106. Brush rollers 302 for cleaning lint from the lower rollers 106 are fixedly mounted on the outer circumferential surfaces of the three rotating shafts 301. One end of the three rotating shafts 301 extends to the outer wall of the other set of support plates 1 and is fixedly mounted with gears 303. The three gears 303 are meshed with each other. Another set of support plates 1 has a drive motor 304 fixedly installed on its outer side wall. The output end of the drive motor 304 is fixedly connected to one of the rotating shafts 301. The outer top surface of the collection box 102 has four corresponding and through holes 305. The inner side wall of each of the four holes 305 is equipped with a suction fan 306. The inner top surface of the collection box 102 is connected to the four holes 305 through a conduit 307. The outer side wall of the collection box 102 is rotatably installed with a sealing door 308. The outer peripheral surface of the multiple lower rollers 106 is textured. When the upper roller 105 and lower roller 106 rotate and perform the drafting operation, the drive motor 304 is started to drive one of the rotating shafts 301 to drive one of the gears 303 to rotate. One of the gears 303 drives the other two gears 303 to rotate through meshing transmission, thereby causing the three rotating shafts 301 to drive the brush roller 302 to rotate synchronously to clean the cotton lint attached to the outer peripheral surface of the lower roller 106 and the outer top surface of the collection box 102. When the cotton lint is raised, the suction fan 306 is started to suck the cotton lint into the guide tube 307 and then into the collection box 102 for centralized treatment. This effectively ensures the cleanliness of the lower roller 106 during the drafting operation, extends the maintenance cycle of the lower roller 106, and reduces the impact of cotton lint attached to the lower roller 106 on the equipment.

[0027] The working principle of this utility model is as follows: When in use, the cotton strip is first transported from the inside of the transmission box 101 to the guide plate 103, and then output along the guide strip hole. After that, it is transported along the guide seat 104 to the rotating lower roller 106 and upper roller 105 for stretching operation.

[0028] Meanwhile, when replacing or maintaining the lower roller 106 and the upper roller 105, first turn the positioning screw 205 to release the fixed relationship of the slider 202. Then, grasp the handle 207 and the handle 208 in sequence to pull the slider 202 to separate it from the slide groove 201. Then, let one end of the multiple upper rollers 105 and the lower roller 106 detach from the inside of the fixing sleeve 204 and take them out along the inner rectangle of the slide groove 201. Then, turn and remove the positioning screw 206 to let the other end of the multiple upper rollers 105 and the lower roller 106 detach from the inside of the fixing sleeve 203, so as to maintain and replace them. At the same time, the reverse operation can be used to quickly install them, thereby improving work efficiency.

[0029] Meanwhile, as the upper roller 105 and lower roller 106 rotate and perform the drafting operation, the drive motor 304 is started to drive one of the rotating shafts 301 to drive one of the gears 303 to rotate. One of the gears 303 drives the other two gears 303 to rotate through meshing transmission, thereby causing the three rotating shafts 301 to drive the brush roller 302 to rotate synchronously, so as to clean the cotton lint attached to the outer peripheral surface of the lower roller 106 and the outer top surface of the collection box 102, thereby effectively ensuring the cleanliness of the lower roller 106 during the drafting operation.

[0030] Then, when the swept-down cotton lint is raised, the suction fan 306 is activated simultaneously to suck in the cotton lint and draw it into the collection box 102 through the conduit 307 for centralized processing.

[0031] Finally, by opening the sealed door 308, the cotton lint inside the collection box 102 can be recycled.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
