Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a yarn winding device and its winding process. Background Technology

[0002] In the textile processing industry, warping machines are typically used to wind yarns, arranging multiple yarns on the bobbin in parallel according to specified lengths and tensions and winding them into a warp beam to prepare for subsequent weaving.

[0003] Existing warping machines have certain drawbacks in use. For example, they work by rotating the warp beam winding roller to wind the incoming yarn. Once the yarn on the winding roller reaches a set length, the machine stops the roller. The operator then needs to cut the yarn connected to the winding roller and gather the cut ends together on the machine, attaching them to the machine's tilting frame (to prevent the ends from falling off). Only then can the wound warp beam be unloaded, which is inconvenient. Summary of the Invention

[0004] This invention provides a yarn winding device and its winding process, which can solve the problem in the prior art that it is inconvenient to cut and temporarily fix the connected yarn after the warp winding roller has finished winding.

[0005] A yarn winding device includes a warping machine body, on which a warp beam winding roller is rotatably mounted. Two transverse guide rollers and a vertical guide roller are rotatably mounted on the inner wall of the warping machine body. A left electric push rod and a right electric push rod are movably mounted between the inner walls of the warping machine body. A left L-shaped plate is fixed to the end of the telescopic end of the left electric push rod, and an upper cutting blade is fixed to one side of the left L-shaped plate.

A synchronous displacement mechanism and a relative displacement mechanism are provided within the warping machine body. A thread pressing mechanism and an auxiliary feeding mechanism are also provided on the warping machine body.

[0006] As a further technical solution of the present invention, one end of both the left L-shaped plate and the right L-shaped plate is arc-shaped.

[0007] As a further technical solution of the present invention, the relative displacement mechanism includes a mounting base, a sliding groove is provided on the upper end face of the mounting base, a left sliding block and a right sliding block are slidably arranged in the sliding groove, a left electric push rod is fixed to the upper end face of the left sliding block, a right electric push rod is fixed to the upper end face of the right sliding block, a lead screw is rotatably arranged on the inner wall of the sliding groove, the lead screw thread passes through the left sliding block and the right sliding block, and a working motor for cooperating with the rotation of the lead screw is fixed on one side of the mounting base.

[0008] As a further technical solution of the present invention, the synchronous displacement mechanism includes two lateral grooves formed on the inner wall of the warping machine body, an electric slide rail is fixed between the two lateral grooves, an electric slider is slidably arranged in the electric slide rail, and a mounting base is fixed to the upper end face of the electric slider.

[0009] As a further technical solution of the present invention, the auxiliary feeding mechanism includes a movable seat movably disposed on the inner wall of the warping machine body, the movable seat having a cavity, a movable mounting plate being disposed on one side of the movable seat, one end of the movable mounting plate being movably inserted into the cavity, an elastic unit being disposed in the cavity to cooperate with the movable mounting plate, an abutment plate being fixed at the end of the movable mounting plate away from the cavity, and a translation unit being disposed on the warping machine body to cooperate with the movable seat.

[0010] As a further technical solution of the present invention, the elastic unit includes a plurality of guide rods fixed to one side of the movable mounting plate, one end of each guide rod movably passing through the movable seat, and a plurality of springs fixed between the cavity and the movable mounting plate, each spring being movably sleeved on the outer surface of the guide rod.

[0011] As a further technical solution of the present invention, the translation unit includes two lateral sliding grooves opened on the inner wall of the warping machine body, a lateral slider is slidably arranged in each lateral sliding groove, a movable seat is fixed between the two lateral sliders, and a translation electric push rod is fixed on the inner wall of each lateral sliding groove, the end of the telescopic end of the translation electric push rod is fixedly connected to the lateral slider.

[0012] As a further technical solution of the present invention, the pressing mechanism includes a U-shaped frame fixed to the upper end face of the warping machine body, and two lifting electric push rods are fixedly arranged through the upper end face of the U-shaped frame, and the same pressing plate is fixed to the end of the telescopic end of the two lifting electric push rods.

[0013] As a further technical solution of the present invention, an air extraction hood is fixed on one side of the U-shaped frame, and multiple branch air pipes are connected to the upper end face of the air extraction hood. One end of the multiple branch air pipes is connected to the same main air pipe. A filter interception box and an air extraction pump are fixed on one side of the warping machine body. One end of the main air pipe is connected to the air inlet of the filter interception box, and a connecting pipe is connected between the air outlet of the filter interception box and the air inlet of the air extraction pump.

[0014] A yarn winding process, the specific steps of which are as follows: Step 1: The warping machine body drives the warp beam winding roller to rotate and wind the conveyed yarn body. When the yarn body on the warp beam winding roller is wound to the specified length, the warp beam winding roller stops rotating. Step 2: The pressing mechanism works, pressing down the yarn body located on the transverse guide roller. At this time, the yarn body located between the transverse guide roller and the warp winding roller is in a taut state. Step 3: The telescopic ends of the left and right electric push rods extend by half of their total stroke, pushing the corresponding left and right L-shaped plates to move until the upper and lower cutting blades move to one side of the yarn body. Then, under the action of the relative displacement mechanism, the left and right electric push rods are brought closer to each other, causing the upper and lower cutting blades to move closer to each other. During this process, the yarn body located between the left and right L-shaped plates is cut off. Step 4: The left electric actuator extends a certain distance, while the right electric actuator retracts a certain distance. During this process, the left and right L-shaped plates move relative to each other, working in conjunction with the contact layer to gather the ends of the cut yarn body together as much as possible. Step 5: Under the action of the relative displacement mechanism, the left electric push rod and the right electric push rod are moved away from each other. Then, the telescopic ends of the left electric push rod and the right electric push rod are fully retracted, thereby driving the left L-shaped plate and the right L-shaped plate away from the yarn body. Step six: Under the action of the synchronous displacement mechanism, the left and right electric push rods are moved synchronously to the next cutting area until the cutting and gathering of all yarn bodies between the transverse guide roller and the warp winding roller are completed.

[0015] The beneficial effects of this invention are: 1. In use, the warping machine body drives the warp beam winding roller to rotate, winding the conveyed yarn body. When the yarn body on the warp beam winding roller is wound to a specified length (working principle is the prior art), the warp beam winding roller stops rotating. At this time, the pressing mechanism works, pressing the yarn body located on the transverse guide roller. At this time, the yarn body located between the transverse guide roller and the warp beam winding roller is in a taut state. Then, the telescopic ends of the left and right electric push rods extend by half of their total stroke, pushing the corresponding left and right L-shaped plates to move until the upper and lower cutting blades move to one side of the yarn body. Then, under the action of the relative displacement mechanism, the left and right electric push rods are brought closer together, causing the upper and lower cutting blades to move closer together. During this process, the yarn body located between the left and right L-shaped plates is cut. At this point, the cut end of the yarn body is located between the left and right L-shaped plates. Then, the left electric push rod extends a certain distance, while the right electric push rod retracts a certain distance. During this process, the left and right L-shaped plates move relative to each other, and the contact layer helps to gather the cut end of the yarn body together as much as possible (in preparation for subsequent connection with the new warp beam winding roller). No manual operation is required. Then, under the action of the relative displacement mechanism, the left and right electric push rods are moved away from each other. Then, the extension and retraction ends of the left and right electric push rods are fully retracted, thereby driving the left and right L-shaped plates away from the yarn body. Then, under the action of the synchronous displacement mechanism, the left and right electric push rods move synchronously to the next cutting area until the cutting and gathering of all yarn bodies between the transverse guide roller and the warp beam winding roller is completed.

[0016] 2. When the yarn body on the warp winding roller is wound to the specified length, the warp winding roller stops rotating. At this time, the translation unit drives the moving seat to move towards the direction close to the warp winding roller. The moving seat drives the movable mounting plate and the abutment plate to move together until one end of the abutment plate abuts against the outer surface of the yarn body on the warp winding roller. When the yarn body between the transverse guide roller and the warp winding roller is cut, the end of the yarn body connected to the warp winding roller will fall downwards. The movable mounting plate and the abutment plate prevent the cut yarn body from falling directly to the ground. When all the yarn body between the transverse guide roller and the warp winding roller is cut, the warp winding roller is rotated counterclockwise. The abutment plate presses the end of the cut yarn body that has fallen down onto the yarn body on the warp winding roller. Then the warping machine body feeds the warp winding roller.

[0017] 3. When in use, the air pump works, which generates airflow around the air extraction hood, sucking in feathers and other particles from the surrounding air. Then, through the branch vent pipe and the main vent pipe, the air passes through the filter interception box. The filter interception box intercepts and adsorbs the feathers in the air that are sucked in. The air then passes through the filter interception box normally and is discharged by the air pump.

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Reference Figures 1-12 A yarn winding device includes a warping machine body 100, on which a warp beam winding roller 101 is rotatably mounted. Two transverse guide rollers 102 and a vertical guide roller 103 are rotatably mounted on the inner wall of the warping machine body 100. A left electric push rod 104 and a right electric push rod 105 are movably mounted between the inner walls of the warping machine body 100. A left L-shaped plate 106 is fixed to the end of the telescopic end of the left electric push rod 104, and an upper cutting blade 107 is fixed to one side of the left L-shaped plate 106. A [missing information - likely a device name or component] is fixed to the end of the telescopic end of the right electric push rod 105. The right L-shaped plate 108 has a lower cutting blade 109 fixed on one side. The left L-shaped plate 106 and the right L-shaped plate 108 are both provided with cutting notches 110 on their opposite surfaces. The left L-shaped plate 106 and the right L-shaped plate 108 are both provided with mounting notches on their opposite surfaces. An abutment layer 111 is fixed in the mounting notch. The warping machine body 100 is provided with a synchronous displacement mechanism and a relative displacement mechanism that work in conjunction with the left electric push rod 104 and the right electric push rod 105. The warping machine body 100 is provided with a crimping mechanism and an auxiliary feeding mechanism.

[0022] The upper cutting blade 107 and the lower cutting blade 109 are staggered vertically. The cutting notches 110 on the left L-shaped plate 106 and the right L-shaped plate 108 are respectively set to correspond to the upper cutting blade 107 and the lower cutting blade 109, so that the opposite surfaces of the left L-shaped plate 106 and the right L-shaped plate 108 can abut together.

[0023] The working principle of the warping machine body 100 is the existing technology. The warp beam winding roller 101 is detachably mounted on the warping machine body 100. The warping machine body 100 drives the warp beam winding roller 101 to rotate and wind the conveyed yarn body 700. The conveyed yarn body 700 is guided by the set transverse guide roller 102 and vertical guide roller 103.

[0024] In use, the warping machine body 100 drives the warp beam winding roller 101 to rotate, winding the conveyed yarn body 700. When the yarn body 700 on the warp beam winding roller 101 is wound to a specified length (working principle is prior art), the warp beam winding roller 101 stops rotating. At this time, the pressing mechanism works, pressing down the yarn body 700 located on the transverse guide roller 102. At this time, the yarn body 700 located between the transverse guide roller 102 and the warp beam winding roller 101 is in a taut state. Then, the left electric push rod 104... The telescopic end of the right electric push rod 105 extends by half of its total stroke, pushing the corresponding left L-shaped plate 106 and right L-shaped plate 108 to move until the upper cutting blade 107 and lower cutting blade 109 are both moved to one side of the yarn body 700. Then, under the action of the relative displacement mechanism, the left electric push rod 104 and right electric push rod 105 are brought closer together, causing the upper cutting blade 107 and lower cutting blade 109 to move closer together. During this process, the yarn body 700 located between the left L-shaped plate 106 and right L-shaped plate 108 is... The yarn body 700 is cut off, at which point the end of the cut yarn body 700 is located between the left L-shaped plate 106 and the right L-shaped plate 108. Then, the left electric actuator 104 continues to extend a certain distance, and the right electric actuator 105 retracts a certain distance. During this process, the left L-shaped plate 106 and the right L-shaped plate 108 move relative to each other, and the contact layer 111 helps to bring the end of the cut yarn body 700 together as much as possible (in preparation for subsequent connection with the new warp beam winding roller 101). No manual operation is required. Then, the relative displacement mechanism operates... When the left electric push rod 104 and the right electric push rod 105 are moved away from each other, the telescopic ends of the left electric push rod 104 and the right electric push rod 105 are fully retracted, thereby driving the left L-shaped plate 106 and the right L-shaped plate 108 away from the yarn body 700. Then, under the action of the synchronous displacement mechanism, the left electric push rod 104 and the right electric push rod 105 are moved synchronously to the next cutting area until the cutting and gathering of all yarn bodies 700 between the transverse guide roller 102 and the warp beam winding roller 101 are completed. It is convenient to use.

[0025] Both the left L-shaped plate 106 and the right L-shaped plate 108 have an arc shape at one end (the end closest to the yarn body 700).

[0026] This facilitates the insertion of the left L-shaped plate 106 and the right L-shaped plate 108 between the taut yarn body 700.

[0027] The relative displacement mechanism includes a mounting base 200. A sliding groove 201 is provided on the upper end face of the mounting base 200. A left sliding block 202 and a right sliding block 203 are slidably disposed in the sliding groove 201. A left electric push rod 104 is fixed to the upper end face of the left sliding block 202, and a right electric push rod 105 is fixed to the upper end face of the right sliding block 203. A lead screw 204 is rotatably disposed on the inner wall of the sliding groove 201. The lead screw 204 is threaded through the left sliding block 202 and the right sliding block 203. A working motor 205 that works in conjunction with the rotation of the lead screw 204 is fixed on one side of the mounting base 200.

[0028] When the lead screw 204 rotates in the forward direction, it will drive the left sliding block 202 and the right sliding block 203 to move closer to each other, thereby driving the left electric actuator 104 and the right electric actuator 105 to move closer to each other. When the lead screw 204 rotates in the reverse direction, it will drive the left sliding block 202 and the right sliding block 203 to move away from each other.

[0029] The synchronous displacement mechanism includes two lateral grooves 300 formed on the inner wall of the warping machine body 100, an electric slide rail 301 fixed between the two lateral grooves 300, an electric slider slidably arranged in the electric slide rail 301, and a mounting base 200 fixed to the upper end face of the electric slider.

[0030] Both the electric slide rail 301 and the electric slider are existing technologies. Through the cooperation of the electric slide rail 301 and the electric slider, the mounting base 200 is driven to move together with the left electric push rod 104 and the right electric push rod 105 to cut the yarn body 700 located in different areas.

[0031] The auxiliary feeding mechanism includes a movable seat 400 movably disposed on the inner wall of the warping machine body 100. A cavity 401 is provided in the movable seat 400. A movable mounting plate 402 is provided on one side of the movable seat 400. One end of the movable mounting plate 402 movably extends into the cavity 401. An elastic unit is provided in the cavity 401 to cooperate with the movable mounting plate 402. An abutment plate 403 is fixed at the end of the movable mounting plate 402 away from the cavity 401. A translation unit is provided on the warping machine body 100 to cooperate with the movable seat 400.

[0032] When the yarn body 700 on the warp winding roller 101 is wound to a specified length, the warp winding roller 101 stops rotating. At this time, the translation unit drives the moving seat 400 to move toward the direction close to the warp winding roller 101. The moving seat 400 drives the movable mounting plate 402 and the contact plate 403 to move together until one end of the contact plate 403 abuts against the outer surface of the yarn body 700 located on the warp winding roller 101. When the yarn body 700 located between the transverse guide roller 102 and the warp winding roller 101 is cut, the yarn body connected to the warp winding roller 101... The end of yarn 700 will fall downwards. The movable mounting plate 402 and the contact plate 403 prevent the cut yarn body 700 from falling directly to the ground. After all the yarn body 700 between the transverse guide roller 102 and the warp beam winding roller 101 has been cut, the warp beam winding roller 101 is rotated counterclockwise. The contact plate 403 presses the end of the cut yarn body 700 that has fallen down onto the yarn body 700 on the warp beam winding roller 101. Then the warping machine body 100 feeds the warp beam winding roller 101.

[0033] The elastic unit includes multiple guide rods 404 fixed to one side of the movable mounting plate 402. One end of each guide rod 404 movably passes through the movable seat 400. Multiple springs 405 are fixed between the cavity 401 and the movable mounting plate 402. Each spring 405 is movably sleeved on the outer surface of the guide rod 404.

[0034] In the initial state, the spring 405 is in the normal state. When the moving seat 400 moves toward the warp winding roller 101, the spring 405 drives the movable mounting plate 402 and the contact plate 403 to move together. When the contact plate 403 abuts against the surface of the yarn body 700 located on the warp winding roller 101, the moving seat 400 continues to move, causing the spring 405 to be squeezed and contracted, thereby applying a reverse force to the movable mounting plate 402 and the contact plate 403, so that the end of the contact plate 403 tightly abuts against the outer surface of the yarn body 700.

[0035] The translation unit includes two lateral slide grooves 406 formed on the inner wall of the warping machine body 100. A lateral slider 407 is slidably arranged in each lateral slide groove 406. The movable seat 400 is fixed between the two lateral sliders 407. A translation electric push rod 408 is fixed on the inner wall of each lateral slide groove 406. The end of the extension end of the translation electric push rod 408 is fixedly connected to the lateral slider 407.

[0036] In the initial state, the telescopic end of the translation electric actuator 408 is in a retracted state. When the moving seat 400 needs to move toward the warp winding roller 101, the telescopic end of the translation electric actuator 408 extends, pushing the lateral slider 407 to move inward, thereby driving the moving seat 400, the movable mounting plate 402 and the contact plate 403 to move together.

[0037] The pressing mechanism includes a U-shaped frame 500 fixed to the upper end face of the warping machine body 100. Two lifting electric push rods 501 are fixedly and through the upper end face of the U-shaped frame 500. The ends of the extension and retraction ends of the two lifting electric push rods 501 are fixed with the same pressing plate 502. The pressing plate 502 is located on the upper surface of the transverse guide roller 102.

[0038] When the yarn body 700 on the warp winding roller 101 is wound to a specified length, the warp winding roller 101 stops rotating. At this time, the telescopic end of the lifting electric push rod 501 extends, pushing the pressure plate 502 downward toward the transverse guide roller 102 until the yarn body 700 is pressed between the transverse guide roller 102 and the pressure plate 502, so as to prevent the yarn body 700 from falling off the transverse guide roller 102 after it is cut.

[0039] A suction hood 600 is fixed to one side of the U-shaped frame 500. Multiple branch ventilation pipes 601 are connected to the upper end of the suction hood 600. One end of the multiple branch ventilation pipes 601 is connected to the same main ventilation pipe 602. A filter interception box 603 and a suction pump 604 are fixed to one side of the warping machine body 100. One end of the main ventilation pipe 602 is connected to the air inlet of the filter interception box 603. A connecting pipe 605 is connected between the air outlet of the filter interception box 603 and the air inlet of the suction pump 604.

[0040] In use, the air pump 604 operates, thereby generating airflow around the air extraction hood 600, which draws in feathers and other particles from the surrounding air into the air extraction hood 600. Then, guided by the branch vent pipe 601 and the main vent pipe 602, the air passes through the filter interception box 603. The filter interception box 603 intercepts and adsorbs the feathers in the air drawn in, and the air passes through the filter interception box 603 normally before being discharged by the air pump 604.

[0041] A yarn winding process, the specific steps of which are as follows: Step 1: The warping machine body 100 drives the warp beam winding roller 101 to rotate and wind the conveyed yarn body 700. When the yarn body 700 on the warp beam winding roller 101 is wound to a specified length, the warp beam winding roller 101 stops rotating. Step 2: The pressing mechanism works, pressing down the yarn body 700 located on the transverse guide roller 102. At this time, the yarn body 700 located between the transverse guide roller 102 and the warp beam winding roller 101 is in a taut state. Step 3: The telescopic ends of the left electric push rod 104 and the right electric push rod 105 extend by half of their total stroke, pushing the corresponding left L-shaped plate 106 and right L-shaped plate 108 to move until the upper cutting blade 107 and the lower cutting blade 109 both move to one side of the yarn body 700. Then, under the action of the relative displacement mechanism, the left electric push rod 104 and the right electric push rod 105 are brought closer to each other, causing the upper cutting blade 107 and the lower cutting blade 109 to move closer to each other. During this process, the yarn body 700 located between the left L-shaped plate 106 and the right L-shaped plate 108 is cut off. Step 4: The left electric actuator 104 continues to extend a certain distance, and the right electric actuator 105 retracts a certain distance. During this process, the left L-shaped plate 106 and the right L-shaped plate 108 move relative to each other, and cooperate with the contact layer 111 to try to bring the ends of the cut yarn body 700 together. Step 5: Under the action of the relative displacement mechanism, the left electric push rod 104 and the right electric push rod 105 are moved away from each other. Then, the telescopic ends of the left electric push rod 104 and the right electric push rod 105 are fully retracted, thereby driving the left L-shaped plate 106 and the right L-shaped plate 108 away from the yarn body 700 respectively. Step six: Under the action of the synchronous displacement mechanism, the left electric push rod 104 and the right electric push rod 105 are moved synchronously to the next cutting area until the cutting and gathering of all yarn bodies 700 between the transverse guide roller 102 and the warp winding roller 101 are completed.

[0042] In use, the warping machine body 100 drives the warp beam winding roller 101 to rotate, winding the conveyed yarn body 700. When the yarn body 700 on the warp beam winding roller 101 is wound to a specified length (working principle is prior art), the warp beam winding roller 101 stops rotating. At this time, the pressing mechanism works, pressing down the yarn body 700 located on the transverse guide roller 102. At this time, the yarn body 700 located between the transverse guide roller 102 and the warp beam winding roller 101 is in a taut state. Then, the left electric push rod 104... The telescopic end of the right electric push rod 105 extends by half of its total stroke, pushing the corresponding left L-shaped plate 106 and right L-shaped plate 108 to move until the upper cutting blade 107 and lower cutting blade 109 are both moved to one side of the yarn body 700. Then, under the action of the relative displacement mechanism, the left electric push rod 104 and right electric push rod 105 are brought closer together, causing the upper cutting blade 107 and lower cutting blade 109 to move closer together. During this process, the yarn body 700 located between the left L-shaped plate 106 and right L-shaped plate 108 is... At the 0-point cutoff, the end of the cut yarn body 700 is located between the left L-shaped plate 106 and the right L-shaped plate 108. Then, the left electric push rod 104 extends a certain distance, and the right electric push rod 105 retracts a certain distance. During this process, the left L-shaped plate 106 and the right L-shaped plate 108 move relative to each other, and the contact layer 111 helps to gather the end of the cut yarn body 700 together as much as possible (in preparation for subsequent connection with the new warp beam winding roller 101). No manual operation is required. Then, the yarn body is moved to the relative displacement machine. Under the action of the mechanism, the left electric push rod 104 and the right electric push rod 105 are moved away from each other. Then, the telescopic ends of the left electric push rod 104 and the right electric push rod 105 are fully retracted, thereby driving the left L-shaped plate 106 and the right L-shaped plate 108 away from the yarn body 700. Then, under the action of the synchronous displacement mechanism, the left electric push rod 104 and the right electric push rod 105 are moved synchronously to the next cutting area until the cutting and gathering of all yarn bodies 700 between the transverse guide roller 102 and the warp beam winding roller 101 are completed. When the yarn body 700 on the warp winding roller 101 is wound to a specified length, the warp winding roller 101 stops rotating. At this time, the translation unit drives the moving seat 400 to move toward the direction close to the warp winding roller 101. The moving seat 400 drives the movable mounting plate 402 and the contact plate 403 to move together until one end of the contact plate 403 abuts against the outer surface of the yarn body 700 located on the warp winding roller 101. When the yarn body 700 located between the transverse guide roller 102 and the warp winding roller 101 is cut, the yarn body connected to the warp winding roller 101... The end of yarn 700 will fall downwards. The movable mounting plate 402 and the contact plate 403 prevent the cut yarn body 700 from falling directly to the ground. After all the yarn body 700 between the transverse guide roller 102 and the warp beam winding roller 101 has been cut, the warp beam winding roller 101 is rotated counterclockwise. The contact plate 403 presses the end of the cut yarn body 700 that has fallen down onto the yarn body 700 on the warp beam winding roller 101. Then the warping machine body 100 feeds the warp beam winding roller 101.

A yarn winding process, applied to the yarn winding equipment according to any one of claims 1-9, characterized in that, The specific steps are as follows: Step 1: The warping machine body (100) drives the warp beam winding roller (101) to rotate and wind the conveyed yarn body (700). When the yarn body (700) on the warp beam winding roller (101) is wound to a specified length, the warp beam winding roller (101) stops rotating. Step 2: The pressing mechanism works to press down the yarn body (700) located on the transverse guide roller (102). At this time, the yarn body (700) located between the transverse guide roller (102) and the warp beam winding roller (101) is in a taut state. Step 3: The telescopic ends of the left electric push rod (104) and the right electric push rod (105) extend by half of their total stroke, pushing the corresponding left L-shaped plate (106) and right L-shaped plate (108) to move until the upper cutting blade (107) and the lower cutting blade (109) move to one side of the yarn body (700).

Step 5: Under the action of the relative displacement mechanism, the left electric push rod (104) and the right electric push rod (105) are moved away from each other. Then, the telescopic ends of the left electric push rod (104) and the right electric push rod (105) are fully retracted, thereby driving the left L-shaped plate (106) and the right L-shaped plate (108) away from the yarn body (700). Step six: Under the action of the synchronous displacement mechanism, the left electric push rod (104) and the right electric push rod (105) are moved synchronously to the next cutting area until the cutting and gathering of all yarn bodies (700) between the transverse guide roller (102) and the warp winding roller (101) is completed.
