Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1 --8. A winding device of a warp knitting machine, comprising a base 1, a fixed side plate 2 being mounted on the upper end of the base 1, a movable side plate 3 being provided on the upper end of the base 1, a winding mechanism 4 being commonly provided between the fixed side plate 2 and the movable side plate 3, the winding mechanism 4 comprising a driving motor 41 mounted on the outer side of the fixed side plate 2, a mounting hole being externally provided on the movable side plate 3, a bearing seat 42 being mounted in the inner cavity of the mounting hole, a support shaft 43 being rotatably connected to the inner cavity of the bearing seat 42, the output ends of the support shaft 43 and the driving motor 41 being connected to a clamping assembly 44, the inner cavity of the clamping assembly 44 being clamped to a plug-in assembly 45, and a winding wheel 46 being commonly connected between the two plug-in assemblies 45.

[0029] A convex groove 8 is provided on the right side of the base 1, and a convex block 7 is movably slidably connected to the inner cavity of the convex groove 8. The upper end of the convex block 7 is connected to the movable side plate 3. A first mounting plate 9 is installed at the bottom end of the inner cavity of the convex groove 8, and a first electric push rod 10 is installed on the outer side of the first mounting plate 9. The output end of the first electric push rod 10 passes through the first mounting plate 9 and is connected to the convex block 7.

[0030] When a new winding wheel 46 needs to be installed, the operator holds the winding wheel 46 that has been wound up by hand, and then opens the first electric push rod 10. The output end of the first electric push rod 10 drives the convex block 7 and the movable side plate 3 to move to the right, so that the support shaft 43 in the inner cavity of the bearing seat 42 outside the movable side plate 3 drives a clamping assembly 44 away from the plug-in assembly 45 on one side of the winding wheel 46. Then the operator manually moves the winding wheel 46 to the right, so that the plug-in assembly 45 on the left side of the winding wheel 46 leaves the clamping assembly 44 on the output end side of the drive motor 41, thereby removing the winding wheel 46 that has been wound up. When loading a new winding wheel 46, the connecting column 451 of the plug-in assembly 45 on one side of the winding wheel 46 is inserted The slot 442 of the socket 441 in the snap-fit ​​assembly 44 on the output end side of the driving motor 41, at the same time, the plug-in block 452 on the outside of the connecting column 451 is inserted into the open groove 443 on the outside of the socket 441, and the limit block 453 on the outside of the connecting column 451 is inserted into the slot 442 in the inner cavity of the slot 442. Then, the movable side plate 3 is reset, so that the other snap-fit ​​assembly 44 is plugged into the plug-in assembly 45 on the outside of the winding wheel 46, thereby effectively snap-fitting and installing the winding wheel 46, thereby facilitating and effectively performing quick installation and disassembly operations on the winding wheel 46, and making it easy to use. The snap-fit ​​assembly 44 and the plug-in assembly 45 inserted into its inner cavity and the winding wheel 46 are driven to rotate by the output end of the driving motor 41, thereby performing winding.

[0031] An in-position detection component 5 is installed at the upper end of the fixed side plate 2. The in-position detection component 5 includes a second mounting plate 51 mounted on the upper end of the fixed side plate 2. A second electric push rod 52 is installed at the lower end of the second mounting plate 51. The output end of the second electric push rod 52 passes through the second mounting plate 51 and is connected to a connecting plate 53. A support plate 54 is connected to one side of the connecting plate 53. An in-position sensor 55 is installed at the lower end of the support plate 54. The in-position sensor 55 is located above the winding wheel 46. The upper end of the second mounting plate 51 is symmetrically connected to a limit column 56 that is movably socketed with the connecting plate 53.

[0032] According to the thickness of the fabric that needs to be wound up by the winding wheel 46, the output end of the second electric push rod 52 drives the connecting plate 53 and the supporting plate 54 to move up and down, thereby driving the in-place sensor 55 to move up and down, and adjusting the vertical distance between the lower end of the in-place sensor 55 and the winding wheel 46. When the winding wheel 46 completes winding, the in-place sensor 55 with the adjusted position detects that the fabric has been wound into place, and transmits this information to the external controller, so that the controller automatically turns off the drive motor 41 and stops winding. At this time, the fabric is already in a taut state, which is convenient for the subsequent tension adjustment mechanism 6 to perform a cutting operation.

[0033] A tension adjustment mechanism 6 is installed at the upper end of the base. The tension adjustment mechanism 6 includes an L-shaped plate 61 installed at the upper end of the base 1. A servo motor 62 is installed at the upper end of one L-shaped plate 61. The output end of the servo motor 62 is connected to a screw rod 63. The lower end of the other L-shaped plate 61 is connected to a positioning column 64. A horizontal plate 65 is provided in front of the fixed side plate 2 and the movable side plate 3. The upper end of the horizontal plate 65 is provided with a threaded hole 67 screwed to the screw rod 63. The upper end of the horizontal plate 65 is provided with a positioning hole 68 movably sleeved with the positioning column 64. A cutting assembly 66 is installed at the upper end of the horizontal plate 65. A tension adjustment groove 610 is provided on the outer side of the horizontal plate 65.

[0034] The cutting assembly 66 includes a support frame 661 installed at the upper end of the horizontal plate 65, a cutting cylinder 662 is installed at the upper end of the support frame 661, the output end of the cutting cylinder 662 is connected to the connecting frame 663, the lower end of the connecting frame 663 is connected to the cutter 664, the upper end of the horizontal plate 65 is provided with a top groove 69 connected to the tensioning force adjusting groove 610, the cutter 664 is located in the inner cavity of the top groove 69, and the bottom end of the inner cavity of the tensioning force adjusting groove 610 is provided with a cutting groove 611, and the cutting groove 611 is V-shaped.

[0035] When the fabric is being wound, as the diameter of the wound fabric becomes larger and larger, the linear speed of the warp knitted fabric will gradually increase while the rotation speed remains unchanged, that is, the warp knitted fabric is tightened during the winding process. Therefore, the servo motor 62 is turned on by an external controller, so that the output end of the servo motor 62 drives the screw rod 63 to rotate, and the cross plate 65 on the outside of the screw rod 63 is limited by the positioning column 64, and the cross plate 65 moves from bottom to top on the outside of the screw rod 63. Since the warp knitted fabric passes through the tensioning force adjustment groove 610 on the outside of the cross plate 65 and is wound onto the winding wheel 46, when the cross plate 65 is in the initial position (located at the upper end of the base 1 and fits with the base 1), the warp knitted fabric is pulled over by the external traction mechanism, and then passes through the tensioning force adjustment groove 61 and is wound onto the winding wheel In the disk 46, the external traction mechanism is at the same height as the winding wheel 46, so that when the diameter of the warp knitted fabric is wound up, the cross plate 65 gradually moves up, reducing the tension of the warp knitted fabric during winding, avoiding excessive tension of the warp knitted fabric during winding, resulting in deformation, affecting the quality of the product itself, and when the warp knitted fabric on the outside of the winding wheel 46 is wound up, the cutting cylinder 662 is started by the external controller, and the output end of the cutting cylinder 662 drives the connecting frame 663 and the cutter 664 at its lower end to move downward, and after the cutter 664 passes through the top groove 69 and the tension adjusting groove 610, the cutter 664 presses the warp into the V-shaped cutting groove 611, effectively cutting the warp, completing the winding operation, and effectively improving the effect of automated winding and cutting.

[0036] Working principle: The utility model is connected by programming control through an external controller with the drive motor 41, the in-position sensor 55, the servo motor 62, the cut-off cylinder 662 and the first electric push rod 10. This PLC programming technology is a prior art and will not be described in detail here. When in use, the operator holds the winding wheel 46 that has been wound up, and then opens the first electric push rod 10. The output end of the first electric push rod 10 drives the convex block 7 and the movable side plate 3 to move to the right, so that the support shaft 43 in the inner cavity of the bearing seat 42 on the outer side of the movable side plate 3 drives a clamping component 44 away from the plug-in component 45 on one side of the winding wheel 46. Then the operator manually moves the winding wheel 46 to the right. The plug-in assembly 45 on the left side of the winding wheel 46 is separated from the clamping assembly 44 on the output end side of the driving motor 41, thereby removing the winding wheel 46 after winding is completed, and installing a new winding wheel 46 again, and then resetting the movable side plate 3, which is convenient for effectively clamping and fixing the winding wheel 46, thereby facilitating and effectively carrying out quick installation and removal operations of the winding wheel 46, and being easy to use. According to the thickness of the fabric that needs to be wound up by the winding wheel 46, the output end of the second electric push rod 52 drives the connecting plate 53 and the supporting plate 54 to move up and down, thereby driving the in-place sensor 55 to move up and down, adjusting the vertical distance between the lower end of the in-place sensor 55 and the winding wheel 46, and when the winding wheel 46 is completed After the position adjustment is completed, the in-place sensor 55 detects that the fabric has been rolled into place and transmits this information to the external controller, so that the controller automatically turns off the drive motor 41 and stops rolling. At this time, the fabric is already in a taut state, which is convenient for the subsequent tension adjustment mechanism 6 to perform a cutting operation. As the diameter of the rolled fabric becomes larger and larger, the linear speed of the warp knitted fabric will gradually increase under the condition of constant rotation speed, that is, the warp knitted fabric is tightened during the rolling process. Therefore, the servo motor 62 is turned on by the external controller, so that the output end of the servo motor 62 drives the screw rod 63 to rotate, and the cross plate 65 on the outside of the screw rod 63 is limited by the positioning column 64. The cross plate 65 is on the outside of the screw rod 63. Moving from bottom to top, as the diameter of the warp knitted fabric becomes larger and larger during winding, the cross plate 65 gradually moves upward, reducing the tension of the warp knitted fabric during winding, avoiding excessive tension of the warp knitted fabric during winding, resulting in deformation, and affecting the quality of the product itself. When the warp knitted fabric on the outside of the winding wheel 46 is wound, the cutting cylinder 662 is started by the external controller, and the output end of the cutting cylinder 662 drives the connecting frame 663 and the cutter 664 at its lower end to move downward. After the cutter 664 passes through the top groove 69 and the tension adjusting groove 610, the cutter 664 presses the warp into the V-shaped cutting groove 611, effectively cutting the warp, completing the winding operation, and effectively improving the effect of automated winding and cutting.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
