[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 6 As shown in the embodiment of the present invention, an intelligent take-up device for a circular knitting machine includes a base 1; a first support rod 2 is fixedly connected to the side wall of the base 1; a second support rod 3 is provided on the top of the base 1; a take-up shaft 4 is rotatably connected to the side wall of the first support rod 2; a servo motor 5 is fixedly connected to the side wall of the first support rod 2 via a fixing block; a rotating shaft is provided at the output end of the servo motor 5; one end of the rotating shaft is fixedly connected to the end of the take-up shaft 4; one end of the take-up shaft 4 is located on the side wall of the second support rod 3; a pair of symmetrically distributed take-up grooves 7 are provided on the outer circular wall of the take-up shaft 4; a traction rope 8 is fixedly connected to the bottom of the take-up groove 7; a traction rod 9 is fixedly connected to one end of the pair of traction ropes 8; a placement groove 10 is provided on the outer circular wall of the take-up shaft 4; the placement groove 10 matches the take-up groove 7; a fixing member is provided on the side wall of the traction rod 9; a pair of... Symmetrically distributed receiving rods; an auxiliary rod is rotatably connected to the adjacent sidewalls of a pair of receiving rods. During operation, the output end of the servo motor 5 drives the take-up shaft 4 on the rotating shaft to rotate, thereby the rotation of the take-up shaft 4 drives the traction rope 8 in the take-up groove 7 to take up. Then, the traction rope 8 drives the traction rod 9 to move during take-up. When taking up the knitted fabric, the worker can fix one end of the knitted fabric with a fixing piece, and then start the servo motor 5 to drive the take-up shaft 4 to rotate. Then, the take-up groove 7 on the take-up shaft 4 takes up the take-up rope, which will pull the traction rod 9 that has been fixed to the knitted fabric. Under the adjustment of the speed of the servo motor 5, the pair of traction ropes 8 are straightened and pulled on the auxiliary rod. When the traction rope 8 has been completely taken up by the take-up groove 7, the traction rod 9 will be in the placement groove 10 of the take-up shaft 4, and the knitted fabric will be taken up on the take-up shaft 4, realizing the effect of convenient take-up of the knitted fabric.

[0029] The fixing component includes a limiting block 11; the side wall of the traction rod 9 is provided with a T-shaped through groove 12; a pair of limiting blocks 11 are placed on the groove wall of the T-shaped through groove 12; a first clamping plate 13 is fixedly connected to the side wall of the limiting block 11; a pair of T-shaped grooves 14 are provided on the side wall of the limiting block 11; a T-shaped block 15 is slidably connected to the groove wall of the T-shaped groove 14; a second clamping plate 16 is fixedly connected to the side wall of the pair of T-shaped blocks 15; a limiting component is provided on the side wall of the limiting block 11; the groove wall of the T-shaped through groove 12... A trigger is provided. During operation, the T-shaped block 15 slides in the T-shaped groove 14, thereby moving the second clamping plate 16. When the corner of the knitted fabric is placed between the second clamping plate 16 and the first clamping plate 13, the trigger will cause the second clamping plate 16 to move towards the first clamping plate 13 to clamp and fix the knitted fabric. Under the action of the limiting member, the limiting block 11 can be limited and fixed in the T-shaped through groove 12, which can clamp and fix knitted fabrics of different widths.

[0030] The limiting component includes an L-shaped block 17; the side wall of the limiting block 11 is provided with a sliding groove 18; the wall of the sliding groove 18 is slidably connected to the L-shaped block 17; the wall of the T-shaped through groove 12 is provided with a set of locking grooves 19; the locking grooves 19 match the L-shaped block 17. During operation, when the L-shaped block 17 slides in the sliding groove, when one end of the L-shaped block 17 enters the locking groove 19, it will limit the lateral movement of the limiting block 11 in the T-shaped through groove 12, thereby achieving the effect of limiting the lateral movement of the limiting block 11 in the T-shaped through groove 12.

[0031] The trigger includes a locking block 20; a pair of locking blocks 20 are placed on the wall of the T-shaped through groove 12; the side wall of the locking block 20 is trapezoidal; the pair of locking blocks 20 are connected to each other by a stop rod 21; the side wall of the stop rod 21 is provided with a square groove 33; an extension rod 30 is placed in the square groove 33; a set of protrusions 31 are fixed to the side wall of the extension rod 30; a set of concave grooves 32 are provided on the side wall of the square groove 33; the concave grooves 32 match the protrusions 31. During operation, due to the trapezoidal shape of the locking block 20, after the L-shaped block 17 limits the limiting block 11, the user can push the stop rod 21, so that the locking block 20 squeezes the limiting block 11. Under the action of the trapezoidal shape of the locking block 20, the limiting block 11 is squeezed to contact the bottom of the T-shaped through groove 12, so that the limiting block 11 is squeezed by the bottom of the T-shaped through groove 12 and the... The locking block 20 limits the movement of the fabric, and its trapezoidal shape also presses the second clamping plate 16, causing it to move towards the first clamping plate 13. This clamps and fixes the knitted fabric between the first clamping plate 13 and the second clamping plate 16. Under the action of the extension rod 30 on the abutment rod 21, when the traction rod 9 is in the placement groove 10 of the take-up shaft 4, the extension rod 30 can first disengage from the abutment rod 21 through the square groove 33 of the abutment rod 21. When it is necessary to release the fixation of the knitted fabric by the second clamping plate 16, the protrusion 31 of the extension rod 30 can be inserted into the concave groove 32 of the square groove 33, and then the extension rod 30 can be pulled, thereby causing the abutment rod 21 to slide against the locking block 20 in the T-shaped through groove 12, so that the second clamping plate contacts the knitted fabric, making it convenient to release the knitted fabric between the first clamping plate 13 and the second clamping plate 16.

[0032] The outer circular wall of the take-up shaft 4 is slidably connected to a pair of symmetrically distributed limiting plates 22; the side walls of the first support rod 2 and the second support rod 3 are both threadedly connected to threaded rods 23; the side walls of the pair of threaded rods 23 are respectively rotatably connected to the side walls of the limiting plates 22. During operation, when the user rotates the threaded rods 23, the threads on the first support rod 2 and the second support rod 3 rotate, which causes the limiting plates 22 to slide on the take-up shaft 4 under the rotation of the threaded rods 23. This limits the side walls of the knitted fabric when it is taken up by the take-up shaft 4, preventing unevenness from occurring on the side walls of the knitted fabric when the take-up on the take-up shaft 4 is completed.

[0033] One end of the take-up shaft 4 is fixedly connected to a square block 24; a circular block 29 is rotatably connected to the side wall of the second support rod 3; the side wall of the circular block 29 is provided with a square through groove; the square block 24 matches the square through groove; the side wall of the second support rod 3 is provided with a movable part. During operation, the square block 24 is in the square through groove of the circular block 29, and under the action of the movable part, the second support rod 3 can be disengaged from the take-up shaft 4, making it convenient to remove the knitted fabric that has been wound up on the take-up shaft 4.

[0034] The movable component includes an L-shaped groove 25; the side wall of the base 1 is provided with an L-shaped groove 25; one end of the second support rod 3 is slidably connected to the bottom of the L-shaped groove 25. During operation, by sliding the second support rod 3 on the bottom of the L-shaped groove 25, the second support rod 3 can be disengaged from the side wall of the take-up shaft 4, making it convenient to extract the knitted fabric on the take-up shaft 4.

[0035] The side wall of the L-shaped groove 25 is provided with a slot 26; the groove wall of the L-shaped groove 25 is provided with a sliding groove; a locking strip 27 is slidably connected to the groove wall of the sliding groove; the locking strip 27 matches the slot 26. During operation, the locking strip 27 slides in the sliding groove. When one end of the locking strip 27 is inserted into the slot 26, it limits the sliding of the second support rod 3 in the L-shaped groove 25, thereby fixing the movement of the second support rod 3.

[0036] The side wall of the traction rod 9 is rounded. During operation, the rounded corners on the traction rod 9 facilitate its easy entry into the placement slot 10.

[0037] The side wall of the traction rod 9 is provided with magnetism; the bottom of the placement groove 10 is provided with a pair of symmetrically distributed electromagnets 28; the traction rod 9 is matched with the electromagnets 28. When working, the electromagnets 28 are on the bottom of the placement groove 10, and when the electromagnets 28 are energized, the traction rod 9 will be magnetically attracted to the bottom of the placement groove 10, so that the traction rod 9 can be fixed in the placement groove 10.

[0038] Working principle: The servo motor 5 drives the take-up shaft 4 on the rotating shaft to rotate. The rotation of the take-up shaft 4 drives the traction rope 8 in the take-up groove 7 to take up the yarn. Then, the traction rope 8 drives the traction rod 9 to move during the take-up. When taking up the knitted fabric, the worker can fix one end of the knitted fabric with a fastener, and then start the servo motor 5 to drive the take-up shaft 4 to rotate. Then, the take-up groove 7 on the take-up shaft 4 takes up the take-up rope, which will pull the traction rod 9 that has been fixed to the knitted fabric. Under the speed adjustment of the servo motor 5, the pair of traction ropes 8 are straightened and pulled on the auxiliary rod. When the traction rope 8 has been completely taken up by the take-up groove 7, the traction rod 9 will be in the placement groove 10 of the take-up shaft 4, and the knitted fabric will be taken up on the take-up shaft 4. This design facilitates the winding of knitted fabrics. The T-shaped block 15 slides within the T-shaped groove 14, causing the second clamping plate 16 to move. When the corner of the knitted fabric is placed between the second clamping plate 16 and the first clamping plate 13, the trigger mechanism moves the second clamping plate 16 towards the first clamping plate 13, clamping and fixing the knitted fabric. The limiting member allows the limiting block 11 to be positioned and fixed within the T-shaped through groove 12, enabling clamping and fixing of knitted fabrics of different widths. When the L-shaped block 17 slides within the sliding groove, and one end of the L-shaped block 17 enters the locking groove 19, it limits the lateral movement of the limiting block 11 within the T-shaped through groove 12, thus controlling the lateral movement of the limiting block 11 within the T-shaped through groove 12. The trapezoidal shape of the locking block 20 limits the movement of the material. After the L-shaped block 17 limits the limiting block 11, the user can push the abutment 21, causing the locking block 20 to press against the limiting block 11. Under the action of the trapezoidal shape of the locking block 20, the limiting block 11 is pressed against the bottom of the T-shaped through groove 12, so that the limiting block 11 is limited by the bottom of the T-shaped through groove 12 and the locking block 20. At the same time, the trapezoidal shape of the locking block 20 also presses against the second clamping plate 16, causing the second clamping plate 16 to move towards the first clamping plate 13, clamping and fixing the knitted fabric between the first clamping plate 13 and the second clamping plate 16. Under the action of the extension rod 30 on the abutment 21, when the traction rod 9 is in the placement groove 10 of the take-up shaft 4, By extending the extension rod 30 within the square groove 33 of the abutment rod 21, the extension rod 30 can first disengage from the abutment rod 21. When it is necessary to release the second clamping plate 16 from the knitted fabric, the protrusion 31 of the extension rod 30 can be inserted into the concave groove 32 of the square groove 33, and then the extension rod 30 can be pulled, thereby causing the abutment rod 21 to slide against the locking block 20 within the T-shaped through groove 12, so that the second clamping plate contacts the knitted fabric, facilitating the release of the knitted fabric from the first clamping plate 13 and the second clamping plate 16. By rotating the threaded rod 23, the threads on the first support rod 2 and the second support rod 3 rotate, causing the limiting plate 22 to slide on the take-up shaft 4 under the rotation of the threaded rod 23, so that when the knitted fabric is taken up by the take-up shaft 4...To prevent unevenness on the sidewalls of the knitted fabric after winding on the take-up shaft 4, the square block 24, located within the square slot of the circular block 29, allows the second support rod 3 to disengage from the take-up shaft 4 under the action of a moving component. This facilitates the removal of the wound-up knitted fabric from the take-up shaft 4. Furthermore, the second support rod 3 slides on the bottom of the L-shaped groove 25, allowing it to disengage from the sidewalls of the take-up shaft 4 and facilitating the extraction of the knitted fabric from the take-up shaft 4. The retaining strip 27 slides within the groove. When one end of the retaining strip 27 is inserted into the retaining groove 26, it limits the sliding of the second support rod 3 within the L-shaped groove 25, thus fixing the movement of the second support rod 3. The rounded corners on the traction rod 9 facilitate its easy entry into the placement groove 10. When the electromagnet 28 is energized, it magnetically attracts the traction rod 9 to the bottom of the placement groove 10, thus securing the traction rod 9 within the placement groove 10.
