[0031] In order to better understand the purpose, structure and function of the utility model, the quantitative shearing device for cotton yarn spinning of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 7 As shown, an embodiment of the utility model provides a quantitative shearing device for cotton yarn weaving, including a processing box 100 for installing processing equipment, a reeling portion 200 for reeling a large roll of cotton yarn is installed on one side of the upper end of the processing box 100, a first conveying portion 300 and a second conveying portion 500 for clamping and conveying the cotton yarn are installed on one side of the reeling portion 200, a shearing unit 400 for shearing the cotton yarn is arranged in the middle of the first conveying portion 300 and the second conveying portion 500, the first conveying portion 300 and the second conveying portion 500 are installed on the upper surface of the processing box 100, a positioning frame 600 for positioning and guiding the cotton yarn is installed on one side of the first conveying portion 300, and a reeling portion 700 for reeling and storing the conveyed cotton yarn is installed on the other end of the second conveying portion 500.

[0033] When it is necessary to divide the large roll of cotton yarn into rolls, the large roll of cotton yarn is placed on the upper end of the unwinding part 200 for fixing, and then one end of the yarn is passed through the positioning wheel and moved to the lower end of the first conveying part 300. The first conveying part 300 can carry the yarn through the middle of the shearing unit 400 installed on one side. If the yarn is cut, the yarn at the lower end of the first conveying part 300 passes through the shearing unit 400, and then is conveyed to the winding part 700 by the second conveying part 500 installed on the other side of the shearing unit 400, the operator can perform knotting and winding. The first conveying part 300 and the second conveying part 500 are matched to transmit the broken part after shearing to avoid the yarn breakage affecting the winding operation and ensure that the broken part can be transported after shearing.

[0034] The shearing unit 400 includes a cutting frame 410 and a lifting frame 420 for shearing and weaving cotton yarn. The cutting frame 410 and the lifting frame 420 are matched and installed in a snap-fitting manner. A first support rod 430 and a second support rod 440 for fixing and installing them are fixedly installed on one side of the cutting frame 410 and the lifting frame 420. The lower ends of the first support rod 430 and the second support rod 440 are driven to rotate by a rotating gear 450. The rotating gear 450 is movably installed inside the box body at the lower end of the inner cavity of the processing machine box 100 through a bearing. Adjustment racks 460 for driving the first support rod 430 and the second support rod 440 to lift and lower are meshed and installed on both sides of the rotating gear 450. The adjusting racks 460 are fixedly installed on the sides of the first support rod 430 and the second support rod 440. A push block for driving the first support rod 430 to lift and lower is fixedly installed on the lower end of the first support rod 430, and the lifting cylinder is connected to the push block.

[0035] When cutting the cotton yarn, the push block installed on the upper end of the lifting cylinder can be pushed to drive the first support rod 430 to rise, and then the cutting frame 410 fixedly installed on one side rises accordingly, so that the first conveying part 300 can pass through, and the first support rod 430 drives the cutting frame 410 to descend for cutting. At the same time, the rotating gear 450 arranged at the lower end drives the adjusting rack 460 to move, and the second support rod 440 drives the lifting frame 420 to rise upward, matching the descending cutting frame 410 for cutting operation, which is convenient for cutting and prevents the spinning line from having too large an angle change during the cutting process to avoid breakage.

[0036] The first conveying part 300 includes a first clamping plate 310 and a second clamping plate 320 for clamping and conveying the yarn. The second clamping plate 320 is controlled by an opening and closing cylinder arranged at the upper end. A first movable frame 330 for driving the first clamping plate 310 and the second clamping plate 320 to move is fixedly installed on the upper end of the first clamping plate 310. The first movable frame 330 is movably installed on one side for supporting and driving a first support frame 340. The first clamping plate 310 and the second clamping plate 320 are installed on the upper end of the processing machine box 100 through the first support frame 340.

[0037] When the cut yarn is transmitted, the first clamping plate 310 and the second clamping plate 320 can be clamped together by a cylinder, and then the first movable frame 330 drives the first clamping plate 310 and the second clamping plate 320 to slide on one side of the first support frame 340, thereby driving the yarn to move, which is convenient for the movement and transmission of the yarn.

[0038] The unwinding section 200 includes a positioning plate 210 for mounting a support and a mounting disk 220 mounted on the upper end of the positioning plate 210 for mounting a wire coil. A fixing rod for mounting the coil is fixedly mounted in the middle of the mounting disk 220. Positioning rods 240 for tightening and positioning the coil are evenly arranged on one side of the upper end of the mounting disk 220. The positioning rods 240 are fixedly mounted on the upper end of a guide cylinder 230 that is slidably mounted inside the mounting disk 220. The guide cylinder 230 is slidably mounted in the inner cavity of the mounting disk 220.

[0039] Before the mounting plate 220 is rotated to pay off the yarn, the yarn bobbin can be mounted on the upper end of the positioning rod 240, and then the evenly arranged guide cylinders 230 drive the positioning rod 240 installed on the upper end to expand, thereby fixing the yarn bobbin to prevent the bobbin from shaking during the pay-off process and affecting the pay-off operation.

[0040] Both sides of the interior of the first mobile frame 330 and the second mobile frame 530 are arranged with rotating wheels 511 for driving the first mobile frame 330 and the second mobile frame 530 to move, and the upper end of the rotating wheel 511 is provided with a moving belt 512 for driving the first mobile frame 330 and the second mobile frame 530 to move. The first mobile frame 330 and the second mobile frame 530 are slidably mounted on the upper end of the slide rails set at the upper ends of the first mobile frame 330 and the second mobile frame 530, and the moving belt 512 is fixedly connected to one side of the first mobile frame 330 and the second mobile frame 530.

[0041] When the second moving frame 530 clamps and moves the yarn, the motor drives the rotating wheel 511 to rotate, and then drives the moving belt 512 to move, and further drives the second moving frame 530 to move, so as to transport and move the yarn.

[0042] Specifically, a fixing plate 540 for installation is fixedly installed at the upper end of the moving belt 512, and a positioning pressure plate 550 for fixing the textile is movably installed at the upper end of the fixing plate 540. The positioning pressure plate 550 is lifted and rotated by a rotating cylinder movably installed at the lower end. When the positioning pressure plate 550 moves the yarn, the rotating cylinder drives the positioning pressure plate 550 to rise upward, and when descending, the rotating cylinder drives the positioning pressure plate 550 to rotate and descend, thereby pressing the yarn against the lower end of the positioning pressure plate 550, which is convenient for driving the yarn to move, and the rotating and lifting positioning pressure plate 550 can facilitate the fixing of the yarn and facilitate moving the positioning pressure plate 550 to the upper end of the yarn.

[0043] Specifically, the positioning frame 600 includes a first guide roller 610 and a second guide roller 620 for guiding and conveying the yarn. The first guide roller 610 is fixedly installed on the upper end of the upper frame of the processing box 100, and the second guide roller 620 is movably installed inside a fixed frame 630 installed on the upper end of the processing box 100. In the process of conveying the yarn, the first guide roller 610 and the second guide roller 620 clamp and guide the yarn for feeding, so that the yarn is transmitted smoothly.

[0044] Specifically, the central axis fixed on both sides of the second guide roller 620 is movably installed in the slot opened inside the fixed frame 630, and the height is adjusted by the lifting spring 640 movably installed inside. The second guide roller 620 that can be lifted and lowered can avoid scratching damage to the yarn during transmission, which makes it inconvenient to use.

[0045] Specifically, the second conveying part 500 includes a second support frame 510 for supporting installation and a sensor 520 installed on the upper end of the second support frame 510 for detecting whether there is yarn passing through. The upper end of the second support frame 510 is movably installed with a second movable frame 530 for driving the yarn to move. The internal parts of the first movable frame 330 and the second movable frame 530 are the same. The sensor 520 can be used to return a signal to determine whether the yarn is fixed, so that the operator can cut the yarn and then re-wind it, which is convenient for the operation.

[0046] A quantitative shearing device for cotton yarn weaving works in the following way: when a large roll of cotton yarn needs to be divided into rolls, the large roll of cotton yarn is placed on the upper end of the unwinding part 200 for fixing, and then one end of the yarn is passed through the positioning wheel and moved to the lower end of the first conveying part 300. The first conveying part 300 can carry the yarn through the middle of the shearing unit 400 installed on one side. If the yarn is sheared, the yarn at the lower end of the first conveying part 300 passes through the shearing unit 400, and then is conveyed to the winding part 700 by the second conveying part 500 installed on the other side of the shearing unit 400, the operator can perform knotting and winding. The first conveying part 300 and the second conveying part 500 are matched to transmit the broken part after shearing to avoid the yarn breakage affecting the winding operation and ensure that the broken part can be transported after shearing.
