Description

Technical Field

[0001] This utility model relates to the field of yarn breaking technology, specifically a yarn breaking device for warping machines. Background Technology

[0002] Warping machines are important pieces of machinery in the textile industry, mainly used to shape yarn into warp beams or weaving beams according to process requirements for subsequent weaving or spinning processes. Their primary function is to improve the uniformity and quality of yarn through a series of process controls, thereby enhancing the efficiency and quality of weaving or spinning.

[0003] For example, a yarn-cutting device for a warping machine, with announcement number "CN222349233U", is installed on the warping machine. The yarn-cutting knife cuts the yarn, and the mounting base is fixedly installed in the mounting cavity on the lead screw assembly through the matching engagement between the limiting hole and the limiting rod, thus securing the yarn-cutting knife. This installation method is not only quick and convenient but also very secure. However, in this method, the knife is moved by the lead screw, and the sliding groove of the knife lacks dustproof measures. During yarn cutting, dust and other debris can enter the housing, affecting the normal operation of the lead screw. Furthermore, the yarn-cutting knife is fixed by engaging the groove and the locking rod, but gaps exist between the grooves, causing instability and wobbling in the fixed position. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the above-mentioned device, which uses a lead screw to drive the cutter, but the cutter's sliding groove is not equipped with dustproof measures. When cutting yarn, dust and other debris may enter the housing, which may affect the normal operation of the lead screw. At the same time, the above-mentioned device uses a sliding groove and a locking rod to fix the yarn-breaking cutter, but there are gaps between the sliding grooves, which leads to unstable fixing of the yarn-breaking cutter and the problem of shaking. Therefore, this invention proposes a yarn-breaking device for a warping machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a yarn breaking device for a warping machine, including a base plate, a cutting groove machined on the upper end of the base plate, a limiting plate fixedly connected to the upper end of the base plate, the outer wall of the limiting plate being slidably connected to a plurality of limiting blocks, the outer walls of the limiting blocks being fixedly connected to a housing, an anti-dust mechanism being provided inside the housing, and a fixing mechanism being provided below the anti-dust mechanism.

[0007] Preferably, an electric telescopic rod is fixedly connected to the lower end of the limiting plate, and a housing is fixedly connected to the output end of the electric telescopic rod.

[0008] Preferably, the dust prevention mechanism includes a servo motor, the output shaft of which is fixedly connected to a reciprocating screw via a coupling, both ends of which are rotatably connected to the housing via bearings, the outer wall of the reciprocating screw is slidably connected to a slider, and a dust baffle is fixedly connected to the outer wall of the slider.

[0009] Preferably, the outer walls of the dust baffles are slidably connected to the housing, and the outer walls of the servo motors are fixedly connected to the housing.

[0010] Preferably, the fixing mechanism includes bolts, the outer walls of which are threadedly connected to the fixing plate and the bending plate, the outer wall of the fixing plate is slidably connected to the positioning rod, the ends of the positioning rod are fixedly connected to the bending plate, and the inner wall of the yarn-breaking knife is slidably connected to the positioning rod.

[0011] Preferably, the fixing plate holds the yarn-breaking knife against the bending plate with bolts, and the upper end of the bending plate is fixedly connected to the slider.

[0012] The present invention proposes a yarn-breaking device for a warping machine, which has the following advantages: through the cooperation of the dust-blocking device and the housing, the output shaft of the servo motor rotates to drive the reciprocating screw to move, the reciprocating screw rotates to drive the slider to move back and forth, the slider moves to drive the yarn-breaking knife to move back and forth, the yarn-breaking knife moves back and forth to cut the yarn, and the slider moves while driving the dust-blocking plate to move. The dust-blocking plate moves linearly due to the limitation of the housing. By setting the dust-blocking plate to block the slide groove at the lower end of the housing, dust and broken yarn can be prevented from entering the housing during cutting and affecting the operation of the reciprocating screw.

[0013] By using a fixing mechanism, rotating the bolt forward causes it to disengage from the bending plate. Then, the worker moves the fixing plate outward, and the fixing plate moves vertically, limited by the positioning rod. The worker then aligns the three through holes at the top of the yarn-breaking knife with the positioning rod, and moves the yarn-breaking knife so that the positioning rod inserts into the through holes on the yarn-breaking knife. The positioning rod limits the vertical, horizontal, and rotational movement of the yarn-breaking knife. Then, the worker realigns the three through holes at the top of the fixing plate with the positioning rod and pushes the fixing plate inward. Because of the positioning rod, the bolt and the threaded hole coincide. Rotating the bolt in the opposite direction fixes the yarn-breaking knife to the bending plate. Compared to using a sliding groove for clamping, fixing the yarn-breaking knife with bolts is more stable. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figures 1-5 :

[0022] In this embodiment, a yarn breaking device for a warping machine includes a base plate 1, a cutting groove 2 processed on the upper end of the base plate 1, a limiting plate 7 fixedly connected to the upper end of the base plate 1, and a plurality of limiting blocks 8 slidably connected to the outer wall of the limiting plate 7. The limiting blocks 8 are limited to linear movement by the limiting plate 7.

[0023] The outer walls of the limiting block 8 are all fixedly connected to the box body 4. The box body 4 is equipped with a dust prevention mechanism 5. A fixing mechanism 3 is provided below the dust prevention mechanism 5. An electric telescopic rod 6 is fixedly connected to the lower end of the limiting plate 7. The output end of the electric telescopic rod 6 is fixedly connected to the box body 4. The extension and retraction of the output end of the electric telescopic rod 6 drives the box body 4 to move.

[0024] See attached document Figures 1-2 :

[0025] The dust prevention mechanism 5 includes a servo motor 501. The output shaft of the servo motor 501 is fixedly connected to the reciprocating screw 502 through a coupling. The rotation of the output shaft of the servo motor 501 drives the reciprocating screw 502 to rotate. Both ends of the reciprocating screw 502 are rotatably connected to the housing 4 through bearings.

[0026] The outer wall of the reciprocating screw 502 is slidably connected to the slider 503. The rotation of the reciprocating screw 502 drives the slider 503 to move. The outer wall of the slider 503 is fixedly connected to the dust baffle 504. The movement of the slider 503 drives the dust baffles 504 on both sides to move. The outer walls of the dust baffles 504 are slidably connected to the housing 4. The outer wall of the servo motor 501 is fixedly connected to the housing 4.

[0027] See attached document Figures 1-5 :

[0028] The fixing mechanism 3 includes bolts 301. The outer walls of the bolts 301 are threadedly connected to the fixing plate 302 and the bending plate 303. The outer wall of the fixing plate 302 is slidably connected to the positioning rod 304. The ends of the positioning rod 304 are fixedly connected to the bending plate 303.

[0029] The inner wall of the yarn-breaking knife 305 is slidably connected to the positioning rod 304. The fixing plate 302 presses the yarn-breaking knife 305 against the bending plate 303 by the bolt 301. The yarn-breaking knife 305 is fixed to the bending plate 303 by the bolt 301. The upper end of the bending plate 303 is fixedly connected to the slider 503.

[0030] Working principle:

[0031] The yarn is cut when the warping machine arranges the yarn into warp beams.

[0032] Work process:

[0033] The worker secures the base plate 1 to the warping machine using a threaded rod. When cutting is required, the worker passes the yarn from the front to the back of the box under the machine. By controlling the operation of the warping machine, the yarn is brought to a taut state and stopped. The worker then activates the electric telescopic rod 6, whose output end extends, causing the box 4 to move downwards (e.g., ...). Figure 2 The box 5 is limited by the limiting block 8 to move vertically, the limiting block 8 is limited by the limiting plate 7 to move vertically, the box 4 moves downward to drive the dust prevention mechanism 5 and the fixing mechanism 3 to move downward, and then drive the yarn cutting knife 305 to move downward. After the yarn cutting knife 305 moves downward and enters the cutting groove 2, the yarn below the yarn cutting knife 305 is cut first.

[0034] When the yarn-cutting knife 305 enters the cutting groove 2, the electric telescopic rod 6 is stopped, and then the servo motor 501 is started. The output shaft of the servo motor 501 rotates, driving the reciprocating screw 502 to move. The rotation of the reciprocating screw 502 drives the slider 503 to move back and forth. The reciprocating movement of the slider 503 drives the yarn-cutting knife 305 to move back and forth. When the yarn-cutting knife 305 moves to the right, it cuts the yarn. After the yarn is cut, the yarn-cutting knife 305 moves to the left to reset. At the same time, the slider 503 moves, driving the dust baffle 504 to move. The dust baffle 504 is limited by the linear movement of the housing 4. The dust baffle 504 blocks the slide groove at the lower end of the housing 4 to prevent dust and broken yarn from entering the housing 4 during cutting and affecting the operation of the reciprocating screw 502, thus realizing the yarn-cutting operation. Then, the output end of the electric telescopic rod 6 is controlled to retract to its original position, and the servo motor 501 is stopped at the same time.

[0035] Yarn-cutting knife installation process:

[0036] The worker rotates bolt 301 in the forward direction (e.g.) Figure 3This causes bolt 301 to detach from the bending plate 303. Then, the worker moves the fixing plate 302 outwards. The fixing plate 302 moves vertically, limited by the positioning rod 304. The worker then aligns the three through holes at the upper end of the yarn-breaking knife 305 with the positioning rod 304, and moves the yarn-breaking knife 305 so that the positioning rod 304 inserts into the through holes on the yarn-breaking knife 305 (e.g., ...). Figure 4 The positioning rod 304 limits the vertical, horizontal and rotational movement of the yarn breaker 305. Then, the worker realigns the three through holes at the top of the fixing plate 302 with the positioning rod 304 and pushes the fixing plate 302 inward. Because of the positioning rod 304, the bolt 301 coincides with the threaded hole. Rotating the bolt 301 in the opposite direction fixes the fixing plate 302 to fix the yarn breaker 305 on the bending plate 303.
