Description

Technical Field

[0001] This utility model relates to the field of automatic warping machine technology, specifically to a yarn clamping device for an automatic warping machine. Background Technology

[0002] An automatic warp threading machine is a piece of equipment used in the weaving industry. It automatically guides warp yarns into the weaving process, improving weaving efficiency and accuracy. Currently, when an automatic warp threading machine is in operation, it needs to guide the yarn into the weaving machine. During this process, the yarn needs to be kept taut to prevent it from becoming loose and difficult to guide into the machine. When the yarn is under tension, the pulling force is large, which can easily cause it to break. Broken yarn needs to be quickly and promptly returned to its initial state to avoid affecting the weaving operation. Typically, when the yarn is under tension and breaks, it will quickly retract, making it difficult to return to its original position. This directly reduces work efficiency and increases the difficulty of operation by requiring skilled personnel, thus diminishing the effectiveness of the yarn clamping device on the automatic warp threading machine.

[0003] Therefore, it is necessary to develop an automatic yarn clamping device for warping machines. Utility Model Content

[0004] The purpose of this invention is to provide an automatic warping machine yarn clamping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic warping machine yarn clamping device, including a warping machine frame, a yarn conveying roller group installed on one side of the top of the warping machine frame, an mounting frame installed at the top center of the warping machine frame, fixing plates installed on both sides of the inner top of the mounting frame, and a rotating shaft rotatably connected to the inner front and rear ends of the mounting frame.

[0006] A clamping box is installed on the other side of the top of the threading frame.

[0007] Preferably, a synchronous pulley is installed at the bottom end of the rotating shaft, and a motor is installed at the top front end of the mounting bracket, with the output end of the motor at the front end being fixedly connected to the top end of the rotating shaft at the front end.

[0008] Preferably, a movable seat is threadedly connected to the lower outer wall of the rotating shaft, and support arms are rotatably connected to both outer walls of the movable seat.

[0009] Preferably, one end of the support arm is slidably connected to a movable arm, one end of the movable arm is rotatably connected to the lower side of the outer wall of the fixed plate, and the other end of the movable arm is rotatably connected to a pressure roller.

[0010] Preferably, a telescopic column is installed at the bottom of the inside of the clamping box, and a spring is provided on the upper part of the outer wall of the telescopic column.

[0011] Preferably, an auxiliary roller seat is installed at the top of the telescopic column, a warp feed groove is provided on the upper side of one outer wall of the clamping box, and a cylinder is installed at the top of the clamping box.

[0012] Preferably, a pressure plate is installed at the output end of the cylinder, and a pressure seat is installed on one side of the bottom of the pressure plate.

[0013] Preferably, a clamping block is installed on one outer wall of the pressure plate, the outer wall of the clamping block is slidably connected to the inside of the feed groove, and a clamping plate is provided on both outer walls of the clamping block, and a set of clamping plates is fixedly connected to the pressure plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By installing the auxiliary roller seat at the extension end of the telescopic column on the clamping box, and feeding the yarn sequentially to the auxiliary roller seat via the yarn feeding roller group and the pressure roller, and using the elastic reaction force of the spring fitted on the outer wall of the extension end of the telescopic column, the pressure roller is tensioned by the motor, and then the telescopic column and spring are used to tension the yarn again, ensuring that the yarn is in a taut and non-slack state during the warping process.

[0016] By fixing the pressure seat to the cylinder output end of the clamping box via the pressure plate, and placing the clamping block on the pressure plate in the warp feed groove of the clamping box, when the yarn breaks under tension, the cylinder drives the pressure seat and clamping block to move downwards. The clamping block, in conjunction with the clamping plate, clamps the yarn, and the pressure seat presses down on the auxiliary roller seat, causing the yarn on the auxiliary roller seat to relax. This minimizes the possibility of the yarn breaking again under tension after clamping. Simultaneously clamping one end of the yarn allows for easy retrieval and reset to the working area, reducing yarn retrieval and reset time, and lessening the operational difficulties for technical personnel. This effectively improves the working efficiency of the automatic warping machine and enhances the performance of the yarn clamping device. Attached Figure Description

[0024] This utility model provides the following technical solution: a yarn clamping device for an automatic warping machine, please refer to [link / reference]. Figures 1-5The system includes a warping frame 1, with a yarn conveying roller group 101 mounted on one side of the top of the warping frame 1. A mounting frame 2 is mounted at the center of the top of the warping frame 1. Fixing plates 201 are mounted on both sides of the top of the mounting frame 2. A rotating shaft 3 is rotatably connected to the front and rear ends of the mounting frame 2. A synchronous pulley 301 is mounted at the bottom of the rotating shaft 3.

The two sets of rotating shafts 3 are rotatably connected and correspondingly mounted at the front and rear ends of the mounting frame 2. The synchronous pulleys 301 on the two sets of rotating shafts 3 are connected by a synchronous belt drive. Because the output end of the motor 302 on the front end of the mounting frame 2 is fixedly connected to the front rotating shaft 3, the motor 302 drives and controls the front rotating shaft 3 to rotate forward or backward, synchronously driving... The rear rotating shaft 3 can rotate forward or backward. A movable seat 303 is threadedly connected to the lower outer wall of the rotating shaft 3. Support arms 304 are rotatably connected to the outer walls of both sides of the movable seat 303. A movable arm 305 is slidably connected to one end of the support arm 304. One end of the movable arm 305 is rotatably connected to the lower outer wall of one side of the fixed plate 201. The other end of the movable arm 305 is rotatably connected to the pressure roller 306. The two sets of movable seats 303 are connected to the outer walls of the two sets of rotating shafts 3 by threaded connection. One end of the movable arm 305 is rotatably connected to one side of the fixed plate 201 on the mounting frame 2, and the other end is rotatably connected to the pressure roller 306. According to the fact that one end of the support arm 304 on the movable seat 303 is slidably connected to the outer wall of the movable arm 305, the motor 302 drives the movable seat 303 to move up or down, and adjusts the angle of the pressure roller 306 synchronously.

[0025] A clamping box 4 is installed on the other side of the top of the warping frame 1. A telescopic column 401 is installed at the bottom of the inside of the clamping box 4. A spring 402 is installed on the upper part of the outer wall of the telescopic column 401. An auxiliary roller seat 403 is installed on the top of the telescopic column 401. The auxiliary roller seat 403 is installed at the extension end of the telescopic column 401 on the clamping box 4. The yarn is fed to the auxiliary roller seat 403 by the yarn conveying roller group 101 and the pressure roller 306 in sequence. The spring 402 is installed on the outer wall of the extension end of the telescopic column 401. The elastic reaction force of the spring 402 is used to tension the yarn under the control of the motor 302. Then, the telescopic column 401 and the spring 402 tension the yarn again to ensure that the yarn is in a taut and non-slack state during the warping process. A warping groove 404 is opened on the upper part of the outer wall of one side of the clamping box 4. A cylinder 405 is installed on the top of the clamping box 4. A pressure roller seat 403 is installed at the output end of the cylinder 405. A pressure plate 406 has a pressure seat 407 installed on one side of its bottom. A clamping block 408 is installed on one outer wall of the pressure plate 406. The outer wall of the clamping block 408 is slidably connected to the inside of the feed groove 404.

The holding block 408 is set in the warp feed groove 404 on the clamping box 4. When the yarn breaks under tension, the cylinder 405 drives the pressure seat 407 and the clamping block 408 to move downward. The clamping block 408 cooperates with the clamping plate 409 to clamp the yarn, and the pressure seat 407 presses down on the auxiliary roller seat 403, so that the yarn on the auxiliary roller seat 403 becomes relaxed, so as to avoid the yarn breaking again under tension after clamping.

[0026] Working principle: When using this utility model, two sets of rotating shafts 3 are rotatably connected and installed at the front and rear ends of the mounting frame 2. The synchronous pulleys 301 on the two sets of rotating shafts 3 are connected by synchronous belt drive. The output end of the motor 302 on the front end of the mounting frame 2 is fixedly connected to the front rotating shaft 3, so that the motor 302 drives the front rotating shaft 3 to rotate forward or backward, which can synchronously drive the rear rotating shaft 3 to rotate forward or backward. The two sets of movable seats 303 are threadedly connected to the outer wall of the two sets of rotating shafts 3, and one end of the movable arm 305 is rotatably connected to... On one side of the fixed plate 201 on the mounting frame 2, the other end is rotatably connected to the pressure roller 306. One end of the support arm 304 on the movable seat 303 is slidably connected to the outer wall of the movable arm 305, causing its motor 302 to drive and control the movable seat 303 to move upwards or downwards, synchronously adjusting the angle of the pressure roller 306. The auxiliary roller seat 403 is installed at the extension end of the telescopic column 401 on the clamping box 4, and the yarn is sequentially conveyed from the yarn conveying roller group 101 and the pressure roller 306 to the auxiliary roller seat 403. A spring 402 is fitted on the outer wall of the extension end of the telescopic column 401, utilizing the spring 402... 02 has an elastic reaction force effect, so that the pressure roller 306, controlled by the motor 302, tensions the yarn, and then the telescopic column 401, together with the spring 402, tensions the yarn again, ensuring that the yarn is in a taut and non-slack state during the warp feeding process. By mounting the pressure seat 407 on the output end of the cylinder 405 on the clamping box 4 from the pressure plate 406, and setting the clamping block 408 on the pressure plate 406 in the warp feeding groove 404 on the clamping box 4, when the yarn breaks under tension, the cylinder 405 drives the pressure seat 407 and the clamping block 408 to move downward. The clamping block 408, in conjunction with the clamping plate 409, clamps the yarn, while the pressure seat 407 presses down on the auxiliary roller seat 403, causing the yarn on the auxiliary roller seat 403 to become slack. This minimizes the risk of the clamped yarn breaking again while under tension. Simultaneously, the yarn at one end of the clamping block 408 can be easily retrieved and reset to the working area, reducing the time spent searching for and resetting the yarn, and also reducing the operational difficulties for relevant technical personnel. This effectively improves the working efficiency of the automatic warping machine and enhances the performance of the yarn clamping device.
