DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] Embodiment 1:

[0035] The present application embodiment discloses a warp knitting machine segmentation device. Figure 1 and Figure 2 The warp knitting machine cutting device includes a frame 1, a first cloth drawing roller 2, a second cloth drawing roller 3, a support rod 4 and a cutting tool. The frame 1 is the main frame 1 of the warp knitting machine. The first cloth drawing roller 2 and the second cloth drawing roller 3 are rotatably connected to the frame 1. The support rod 4 is fixedly installed on the frame 1. The first cloth drawing roller 2, the second cloth drawing roller 3 and the support rod 4 are parallel to each other. The first cloth drawing roller 2 and the second cloth drawing roller 3 are both used for traction and limiting of the fabric. The cutting tool is detachably installed on the support rod 4 for cutting the fabric.

[0036] Specifically, in this embodiment, the first cloth-drawing roller 2 is used for allowing the fabric to pass around so as to limit and guide the fabric being transported, and the second cloth-drawing roller 3 is used for winding the fabric. The frame 1 is provided with a motor (not shown in the figure) for driving the second cloth-drawing roller 3 to rotate, and the first cloth-drawing roller 2 is closer to the feeding position of the frame 1 than the second cloth-drawing roller 3. The support rod 4 is in the shape of a square rod and is located above the gap between the first cloth-drawing roller 2 and the second cloth-drawing roller 3.

[0037] When the fabric is conveyed to the first fabric drawing roller 2, it is wound around the first fabric drawing roller 2 from the side of the first fabric drawing roller 2 away from the support rod 4, and then conveyed to the second fabric drawing roller 3 for winding, so that the support rod 4 and the dividing tool are exposed above the fabric between the first fabric drawing roller 2 and the second fabric drawing roller 3, so that the dividing tool can be replaced and adjusted when the fabric is conveyed.

[0038] Reference Figure 3 and Figure 4 As for the segmentation tool, the segmentation tool includes a mounting frame 5, a blade 6 and a locking member 7. The blade 6 is mounted on the mounting frame 5, and the locking member 7 locks the mounting frame 5 to the support rod 4. By matching the mounting frame 5 with different positions in the length direction of the support rod 4, the position of the blade 6 in the length direction of the support rod 4 is adjusted, thereby adjusting the segmentation size of the fabric.

[0039] Specifically, the mounting frame 5 includes a clamping seat 51, an adjusting rod 52 and a limit piece 53. In the present embodiment, the clamping seat 51 is integrally formed, and a square matching groove 8 is provided on one side of the clamping seat 51 so that the clamping seat 51 forms a U-shape with an opening toward the side. The clamping seat 51 can be sleeved onto the support rod 4 from the outside of the support rod 4 through the matching groove 8.

[0040] The adjusting rod 52 is in the shape of a long rod, and the blade 6 is installed at the bottom of the adjusting rod 52 by bolts. The adjusting rod 52 abuts and slides up and down on the side of the clamping seat 51 away from the matching groove 8. The distance between the blade 6 and the fabric is adjusted by moving the adjusting rod 52 relative to the clamping seat 51, thereby changing the contact position of the blade 6 and the fabric and improving the service life of the blade 6.

[0041] The limiting member 53 includes a through rod 531 and a butt joint 532. The through rod 531 is in the shape of a screw and is threadedly connected to the side of the clamping seat 51 that is away from the matching groove 8. The through rod 531 also passes through the adjusting rod 52. The vertical center line of the adjusting rod 52 is provided with an adjusting hole 9 along its own length direction to make way for the through rod 531. The two ends of the adjusting hole 9 that are far away from each other are respectively close to but do not pass through the upper and lower ends of the adjusting rod 52. The adjusting rod 52 slides up and down relative to the through rod 531 and the clamping seat 51 through the adjusting hole 9, and the axial direction of the through rod 531 is perpendicular to the length direction of the adjusting rod 52.

[0042] The abutment 532 is fixed to one end of the penetrating rod 531 away from the clamping seat 51, and the abutment 532 is in the shape of a plum blossom handle. When the abutment 532 is rotated to drive the penetrating rod 531 to be screwed in the direction close to the clamping seat 51 until the abutment 532 is pressed against the side of the adjusting rod 52 away from the clamping seat 51, the abutment 532 and the clamping seat 51 jointly clamp the adjusting rod 52 so that the adjusting rod 52 and the blade 6 are positioned relative to the clamping seat 51.

[0043] Reference Figure 3 and Figure 4 In this embodiment, the locking member 7 is a screw with a plum blossom-shaped handle, and the screw portion of the locking member 7 is threaded from top to bottom through the top of the clamping seat 51 to the matching groove 8. After the clamping seat 51 is sleeved onto the support rod 4, the clamping seat 51 is pressed against the lower surface of the support rod 4 at the bottom wall of the matching groove 8, and then the locking member 7 is threadedly moved to the bottom of the screw to press against the upper surface of the support rod 4, so that the support rod 4 is clamped between the screw and the clamping seat 51, so that the clamping seat 51 is positioned relative to the support rod 4.

[0044] Furthermore, a mounting groove 10 is provided at the bottom of the adjusting rod 52, and the mounting groove 10 passes through one side and two opposite sides of the adjusting rod 52, so that the remaining solid part at the bottom of the adjusting rod 52 forms a mounting portion 11, and the mounting portion 11 is in a square shape and close to the other side of the adjusting rod 52. When the blade 6 is installed, it abuts against the side of the mounting portion 11 facing the mounting groove 10, the rod of the bolt passes through the blade 6 and is threaded onto the mounting portion 11, and the head of the bolt abuts against the side of the blade 6 away from the mounting portion 11, so that the blade 6 is positioned relative to the adjusting rod 52. After the blade 6 is installed in the mounting portion 11, the plate surface of the blade 6 coincides with the vertical center line of the adjusting rod 52, so that the fabric unfolded after cutting is symmetrical along the adjusting rod 52, so that the adjusting rod 52 is located at the center of the fabric roll divided into two rolls, so that the fabric roll is not easy to interfere with the adjusting rod 52 after gradually increasing, and the stability of the fabric roll and the adjusting rod 52 is improved.

[0045] The implementation principle of a warp knitting machine segmentation device in the embodiment of the present application is as follows: the position of the clamping seat 51 relative to the support rod 4 is adjusted to adjust the position of the blade 6 in the length direction of the support rod 4 to adjust the segmentation size of the fabric. The vertical position of the adjustment rod 52 relative to the clamping seat 51 is adjusted to adjust the contact point between the blade 6 and the fabric.

[0046] Embodiment 2:

[0047] The difference between the embodiment of the present application and the first embodiment is that the structure of the card seat 51 is different. Figure 5The clamping seat 51 includes a basic block 12, a moving block 13 and an adjusting member 14. The basic block 12 is installed on the support rod 4. The moving block 13 is adjusted by the adjusting member to move on the basic block 12 along the length direction of the support rod 4, and the through rod 531 is threaded on the moving block 13, so that the moving block 13 drives the adjusting rod 52 and the blade 6 to perform fine adjustment of the position.

[0048] Reference Figure 2 and Figure 3 , wherein the matching groove 8 is provided on one side of the base block 12, and the locking member 7 is threaded on the top of the base block 12, and the locking method of the base block 12 and the support rod 4 is consistent with the locking method of the clamping seat 51 and the support rod 4 in the first embodiment. The moving block 13 is composed of a main body 131 and a connecting part 132, both of which are in a square shape, and the connecting part 132 is fixed at the middle position of the top of the main body 131, and the size of the connecting part 132 is smaller than that of the main body 131.

[0049] The side of the base block 12 away from the matching groove 8 is a vertical plane, and the base block 12 is provided with a sliding hole 15, which includes a first sliding hole 151 and a second sliding hole 152. The first sliding hole 151 is provided on the side of the base block 12 away from the matching groove 8 and penetrates the opposite sides of the base block 12 along the length direction of the support rod 4. The second sliding hole 152 is provided on the top wall of the base block 12 in the first sliding hole 151 and also penetrates the opposite sides of the base block 12. The first sliding hole 151 is used for the main body 131 to slide, and the second sliding hole 152 is used for the connecting part 132 to slide. When the main body 131 is matched with the first sliding hole 151, the side of the main body 131 away from the matching groove 8 exceeds the side of the base block 12 away from the matching groove 8. The through rod 531 is threadedly connected to the side of the main body 131 away from the matching groove 8, and the adjustment rod 52 is clamped between the abutment 532 and the main body 131.

[0050] The positioning member 14 includes a threaded rod 141 and an insert 142. One end of the threaded rod 141 is rotatably connected to the connecting portion 132 through a bearing, and a handle is fixed to the other end of the threaded rod 141. The axial direction of the threaded rod 141 is parallel to the length direction of the support rod 4. The insert 142 is in a square shape. The insert 142 is threadedly sleeved on the outer wall of the threaded rod 141. One side of the base block 12 is provided with an insert groove 16 for the insert 142 to be inserted. The insert groove 16 is located above the first sliding hole 151 and opposite to the second sliding hole 152. After the insert 142 is inserted into the insert groove 16, it is locked to the base block 12 by bolts to install the insert 142. After the insert 142 is installed, the threaded rod 141 enters the second sliding hole 152.

[0051] When it is necessary to fine-tune the position of the blade 6 in the length direction of the support rod 4, the threaded rod 141 is rotated to drive the threaded rod 141 to move relative to the insert block 142, so as to drive the moving block 13 to move along the length direction of the support rod 4, thereby driving the adjustment rod 52 and the blade 6 to move, and the threaded rod 141 is stopped from rotating to position the moving block 13 relative to the base block 12.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
