Description

TECHNICAL FIELD

[0001] The present application relates to the field of textile processing, more particularly to a yarn drum automatic replacement device for sweater fabric weaving. BACKGROUND

[0002] Sweater fabric weaving is a complex process that combines traditional techniques with modern technology, involving yarn selection, weaving equipment, process parameter optimization, and the application of innovative technologies. Commonly used yarns for sweaters include wool, cashmere, cotton, blended yarns (such as 32% cotton + 48% acrylic + 20% polyester), and fancy yarns (loop yarns, gradient color yarns, etc.). Different materials affect the hand feel, elasticity, and style of the fabric. High-count yarns (such as 60-count combed cotton) are suitable for delicate jacquard embroidery, while blended yarns can form a short pile surface through the raising process, increasing the weight (such as 320g / m2) and warmth.

[0003] During sweater fabric weaving, yarn drum replacement is a critical process that directly affects production efficiency and product quality. Depending on different production equipment and process requirements, yarn drum replacement can be divided into two main methods: manual operation and automatic replacement. In terms of safety preparation, the operator must first confirm that the machine is in a completely stopped state. For traditional non-automated textile equipment, the principle of "stop first, then operate" must be followed. The power must be cut off and a warning sign must be hung on the control panel to prevent others from making mistakes. It is also necessary to understand the location of the emergency stop button of the equipment and the basic first aid measures. Only after these preparations are fully completed can the actual yarn drum replacement operation stage begin.

[0004] In the prior art, the bobbin clamping piece of the yarn drum deforms due to high temperature after a long period of operation. On the one hand, this causes the yarn drum to be misaligned or to fall off. On the other hand, the loosening of the yarn drum affects the efficiency of yarn feeding or winding. SUMMARY

[0039] As shown in Figures 2 to 6 The locking assembly 28 comprises limiting grooves 281 arranged on the opposite sides of the left and right rotating seats 21.

[0040] The inside of the limiting groove 281 is slidably connected with a limiting column 282, the opposite faces of the limiting columns 282 on the left and right sides are fixedly connected with the sides away from each other of the clamps 22 between the left and right sides, the yarn drum body 285 is inserted between the clamps 22 on the left and right sides, the inside of the rotating seat 21 is provided with a recess 283, the recess 283 is communicated with the limiting groove 281, and the side away from the limiting groove 281 in the inside of the recess 283 is fixedly connected with the pressure spring 284 between the limiting column 282.

[0041] The sides away from each other of the clamps 22 on the left and right sides are fixedly connected with a magnet ring 286, the upper side of the machine body 1 is provided with an embedding groove 288, the clamps 22 are inserted into the inside of the embedding groove 288 after being moved downward, the upper end of the machine body 1 is provided with a slide 289, the inside of the embedding groove 288 on the left and right sides is fixedly connected with a magnet block 287, the magnet block 287 is in the shape of a "U", the rotating seat 21 is in sliding contact with the inner surface of the magnet block 287 after being moved downward, the magnet ring 286 is magnetically attracted to the magnet block 287, and the slide 289 is in front of the embedding groove 288.

[0042] By adopting the above technical scheme, in the process that the rotating seat 21 drives the clamps 22 to move up and down, the yarn drum body 285 between the two clamps 22 also moves with them, when the rotating seat 21 is at the uppermost position in the guide groove 11, the pressure spring 284 in the recess 283 pushes the limiting column 282, so that the limiting column 282 slides in the limiting groove 281, and after the limiting column 282 moves, the clamp 22 fixedly connected with the limiting column 282 also moves due to the movement of the limiting column 282, finally clamping the yarn drum body 285, when the material winding is completed, the rotating seat 21 drives the clamps 22 to move downward through the limiting column 282, when the magnet rings 286 on the sides away from each other of the two clamps 22 are close to the magnet rings 286 on the left and right sides in the inside of the embedding groove 288, the magnet block 287 gradually attracts the magnet ring 286, so that the limiting column 282 extrudes the pressure spring 284, and the clamp 22 gradually separates from the left and right sides of the yarn drum body 285, when the yarn drum body 285 with the wound material reaches the upper side of the embedding groove 288, because the width of the embedding groove 288 is smaller than the diameter of the yarn drum body 285 with the wound material, the yarn drum body 285 cannot enter the inside of the embedding groove 288, after the two clamps 22 are away from the yarn drum body 285, the yarn drum body 285 slides out of the position between the two clamps 22 through the slide 289, because the yarn drum body 285 clamped by the clamp 22 moves away from the yarn drum body 285 during the downward movement of the guide block 12, the yarn drum body 285 is automatically separated and quickly moves out of the winding working environment, so that the yarn drum body 285 is quickly replaced, and the timely supply of the lubricant is ensured.

[0045] By adopting the above technical scheme, in the process of sliding of the guide block 12 inside the guide groove 11, the laser range finder 34 on the inside upper side of the guide groove 11 can detect the position of the guide block 12 in real time, when the guide block 12 starts to move downward, the information detected by the laser range finder 34 is transmitted to the controller 15, and the driving motor 14 is controlled to stop running, when the guide block 12 starts to move upward from the lowermost inside of the guide groove 11 and moves to the same horizontal line as the snap ring 33, the controller 15 starts the second electric push rod 32 to push the snap ring 33, when the vertical part of the front side of the snap ring 33 is separated from the upper feeding seat 31, the bobbin body 285 on the inclined surface of the upper feeding seat 31 rolls into the two vertical parts of the snap ring 33 after losing the limitation of the snap ring 33, and after the second electric push rod 32 cannot continue to stretch forward, the two ends of the bobbin body 285 will be between the two clamps 22, then the two clamps 22 are pushed by the pressure spring 284 due to losing the adsorption of the magnet plate, so that the two clamps 22 clamp the bobbin body 285, at the same time, the material roller always corresponds to the position of the through hole 23, then the first electric push rod 271 continues to push the guide block 12 upward through the stand 274, when the guide block 12 reaches the uppermost inside of the guide groove 11, the controller 15 controls the first electric push rod 271 to stop running, and the driving motor 14 is started again to drive the rotating seat 21 to rotate, and the second electric push rod 32 also pulls the snap ring 33 back to the original position, after the clamp 22 moves downward to feed the bobbin body 285, if the clamp 22 continues to move upward at this time, the bobbin body 285 of other batches will automatically complete the feeding, so as to realize the automatic feeding and discharging of the bobbin body 285, and the waste generated during the winding of the bobbin body 285 can be sucked away by the suction force generated by the through hole 23.

[0046] As shown in Figure 7 and 8 , the inside and outside of the upper feeding seat 31 are jointly provided with a partition assembly 35, which comprises a first sliding groove 351 opened on the upper and lower sides of the front end of the upper feeding seat 31.
