[0001] This utility model relates to the field of textile technology, specifically to a circular knitting machine based on self-replacing take-up rollers. Background Technology

[0002] The circular knitting machine, also known as a circular weft knitting machine or circular weft machine, is a core piece of equipment in the textile industry used to knit circular fabrics. It produces seamless garments, such as athletic shoe uppers and yoga wear, through one-piece molding technology.

[0003] In the current operation of circular knitting machines, the yarn enters the needle hook through the yarn guide, and then the knitting needles move up and down under the control of the triangular track to form loops and interlock. At this time, the fabric is pulled downward and wound onto the take-up roller to form a roll. During the take-up process, manual replacement is required, which is relatively complicated. After replacement, the winding angle and fixed position need to be adjusted, which reduces the take-up efficiency of the product and thus reduces the processing efficiency of the circular knitting machine. This needs to be optimized and improved. Utility Model Content

[0004] The purpose of this invention is to provide a circular knitting machine based on self-changing take-up rollers, in order to solve the problem mentioned in the background art that the operation of collecting rolled fabric is cumbersome and affects the processing efficiency of the equipment.

A telescopic rotating connector is located on the outer side of the take-up frame, and a storage frame is located on one side of the take-up frame. A collection frame is located at the bottom of the take-up frame. The take-up assembly is used for automatic fabric winding and replacement. The slitting adjustment assembly includes a top plate located at the top of the take-up frame. A lifting and reversing roller is located at the bottom of the top plate, and a movable cutter is located on the outer side of the top plate. The slitting adjustment assembly is used for cutting the fabric during winding.

[0007] Preferably, a take-up roller body is provided in the middle of the inner side of the take-up frame, and a lifting limit plate is connected to the bottom end of the take-up frame.

A collection frame 12 is provided at the bottom of the take-up frame 4. The take-up assembly is used for automatic replacement of fabric winding.

[0026] Specifically, such as Figure 3 As shown, a take-up roller body 6 is provided in the middle of the inner side of the take-up frame 4, and a lifting limit plate 11 is connected to the bottom end of the take-up frame 4. The lifting limit plate 11 moves upward to support, so that the telescopic rotating connectors 5 at both ends can be moved out and released from the clamping of the take-up roller body 6.

[0027] Specifically, such as Figure 3 As shown, a buffer ramp 14 is provided at the front end of the take-up frame 4, and a collection frame 12 is provided at the bottom end of the buffer ramp 14. The take-up roller body 6 rolls along the buffer ramp 14 toward the collection frame 12 under the thrust.

[0028] Specifically, such as Figure 3 As shown, a pressure sensor 13 is provided at the front end of the collection box 12. The pressure sensor 13 monitors the change in pressure value and transmits the signal to the terminal to remind the operator to pick up the collected winding roller body 6.

[0029] Specifically, such as Figure 4As shown, a fixed plate 15 is connected to the rear end of the take-up frame 4, and a telescopic push block 16 is connected to the top of the fixed plate 15. An adjustment groove 18 is provided on the inner side of the storage frame 17, and the telescopic push block 16 is located on the inner side of the adjustment groove 18. It can be telescopically slidably adjusted, which facilitates the telescopic push block 16 to limit the empty take-up roller body 6.

[0030] The slitting adjustment assembly includes a top plate 7, which is located at the top of the take-up frame 4. A lifting and reversing roller 9 is provided at the bottom of the top plate 7, and a movable cutter 10 is provided on the outer side of the top plate 7. The slitting adjustment assembly is used for cutting the fabric during take-up.

[0031] Specifically, such as Figure 3 As shown, the bottom end of the top plate 7 is connected to the pressing adjustment plate 8, and the lifting reversing roller 9 is connected to the bottom end of the pressing adjustment plate 8.

[0034] Specifically, this solution involves the following steps when processing the circular knitting machine: Yarn is introduced through the outer yarn feeder 3, then knitted through the needle plate 2. After being knitted into fabric, it is collected by the take-up roller body 6 inside the take-up frame 4. The telescopic rotating connectors 5 on both sides of the take-up roller body 6 can be rotated and adjusted, allowing for position control. When the take-up roller body 6 needs to be replaced, the position of the lifting and reversing roller 9 and the pressing and adjusting plate 8 are controlled by pressing the telescopic rod inside the adjusting plate 8 for squeezing and positioning. The other end is tightened by rotating the take-up roller body 6, keeping the fabric taut. Then, the lifting limit plate 11 moves upward for support, and the fabric is then... The moving cutter 10 cuts the fabric, and then the telescopic pusher 16 descends, causing the empty take-up roller body 6 inside the inclined storage box 17 to roll inward toward the take-up frame 4. The collected take-up roller body 6 rolls along the buffer ramp 14 toward the collection box 12 under the push force. Then, the pressure sensor 13 monitors the pressure value change and transmits the signal to the terminal to remind the operator to pick up the collected take-up roller body 6. At the same time, the empty storage box 17 is replenished. Then, the telescopic rod inside the top plate 7 drives the pressing adjustment plate 8 and the lifting reversing roller 9 to move down together to close to the empty take-up roller body 6 to position the end of the fabric and improve the stability of collection.
