[0038] Example 1

[0039] See also Figure 1-Figure 7 As shown, a technical solution provided by the present invention is:

[0040] A textile Zhangduan cutting device comprises a workbench 1, on which a supporting box 2 is fixedly arranged, a plurality of cloth guide rollers 3 are rotatably arranged on the right side of the workbench 1, a cloth winding roller 4 is rotatably arranged on the left side of the workbench 1, a cutting device 5 is arranged above the supporting box 2, the interior of the supporting box 2 is hollow, and a plurality of rows of through holes 21 are evenly arranged on the top, transmission rollers 6 are symmetrically rotatably arranged on the left and right sides of the supporting box 2, the top of the transmission roller 6 is on the same horizontal plane as the top of the supporting box 2, a connecting hole 22 is opened on one side of the supporting box 2, the connecting hole 22 is sealedly connected to an external vacuum pump through a pipeline, and negative pressure is generated inside the supporting box 2 by the vacuum pump, so that the Zhangduan cloth can always be tightly attached to the top of the supporting box 2, and an adjustment component 7 is also rotatably arranged on the right side of the workbench 1. When in use, the initially woven satin fabric is moved to the top of the support box 2 via a plurality of cloth guide rollers 3 and the right-side transmission roller 6, and is cut by the cutting device 5. The cut satin passes through the left-side transmission roller 6 and enters the cloth winding roller 4 for winding and collection. When the tail end of the satin is close to the cutting device 5, the through hole 21 is adjusted by adjusting the component 7 so that the inside of the support box 2 is always under negative pressure, and the satin fabric is always tightly attached to the top of the support box 2.

[0041] In this embodiment, if Figure 2 , 7 As shown, the cloth guide rollers 3 are preferably three, and the three cloth guide rollers 3 have the same specifications and are arranged vertically, and are rotatably arranged on the right side of the workbench 1. When in use, the satin fabric first passes through the three cloth guide rollers 3 in sequence, and then passes through the right transmission roller 6, so that the satin fabric can always maintain a certain tension during the movement.

[0042] As a preferred embodiment of this embodiment, the cutting device 5 includes fixing frames 51 symmetrically arranged on the front and rear sides of the top of the workbench 1. Between the two fixing frames 51, guide rods 52 are symmetrically and fixedly arranged. Between the two guide rods 52, a first threaded rod 53 is arranged. The two ends of the first threaded rod 53 are respectively rotatably connected to the fixing frames 51 through bearings. On the outside of one fixing frame 51, a first motor 54 is fixedly arranged. The output end of the first motor 54 penetrates the fixing frame 51 and is fixedly connected to one end of the first threaded rod 53. Between the two fixing frames 51, a moving block 55 is also arranged. On the moving block 55, a threaded hole 56 and two guide holes 57 are opened. The moving block 55 is threadedly connected to the first threaded rod 53 through the threaded hole 56. The two guide rods 52 are respectively movably arranged in the two guide holes 57. At the bottom of the moving block 55, a plurality of cutting knives 58 are evenly arranged. The first motor 54 is a forward and reverse motor. By controlling the first threaded rod 53 to rotate through the first motor 54, the moving block 55 is driven to move along the guide rods 52, so that the cutting knives 58 perform a reciprocating motion to perform flocking treatment on the Zhang satin fabric, reducing manual operation and greatly improving the textile efficiency of Zhang satin.

[0043] In this embodiment, positioning plates 11 are symmetrically arranged on the left side of the workbench 1. The two ends of the rotating shaft of the fabric roller 4 are respectively rotatably connected to the positioning plates 11. On the outside of one positioning plate 11, a second motor 12 is arranged. The output end of the second motor 12 penetrates the positioning plate 11 and is fixedly connected to the rotating shaft of the fabric roller 4. By controlling the rotation of the fabric roller 4 through the second motor 12, the Zhang satin after flocking is wound and collected on the fabric roller 4, which is convenient for the storage and transportation of Zhang satin.

[0044] In this embodiment, guide grooves 23 are also symmetrically arranged on the front and rear sides of the top of the support box body 2. The adjustment assembly 7 includes rotating rods 71 symmetrically rotatably arranged on the outside of the workbench 1. One end of the rotating rod 71 is rotatably connected to the workbench 1 through a bearing. The other end of the rotating rod 71 is fixedly connected to a connecting rod 72. The other ends of the two connecting rods 72 are connected to the same U-shaped fixing frame 73. Inside the U-shaped fixing frame 73, sliding grooves 74 are symmetrically opened. A first adjusting plate 75 is slidably arranged in the U-shaped fixing frame 73. When the U-shaped fixing frame 73 rotates to the highest point, the sliding groove 74 on the U-shaped fixing frame 73 abuts against the guide groove 23, and the two are on the same horizontal plane. When the U-shaped fixing frame 73 rotates to the highest point, the connecting rod 72 abuts against the top end of the workbench 1. At this time, the sliding groove 74 on the U-shaped fixing frame 73 abuts against the guide groove 23. At this time, the first adjusting plate 75 can slide from the sliding groove 74 into the guide groove 23 to block the through hole 21 exposed at the end of the Zhang satin fabric, so that the inside of the support box body 2 always maintains a negative pressure environment.

[0045] Further, a third motor 13 is provided inside the workbench 1, and a first gear 14 is provided outside the workbench 1. The output end of the third motor 13 penetrates through the workbench 1 and is fixedly connected to the first gear 14. A second gear 711 is fixedly sleeved on one of the rotating rods 71, and the first gear 14 meshes with the second gear 711. By controlling the first gear 14 to rotate through the third motor 13, the first gear 14 drives the second gear 711 meshing with it to rotate, thereby driving the U-shaped fixing frame 73 to rotate, so that the U-shaped fixing frame 73 rotates 90° between the initial position and the highest point.

[0046] Further, two support columns 731 are symmetrically arranged at both ends of the side of the U-shaped fixing frame 73 away from the workbench 1. In the initial position, the U-shaped fixing frame 73 is supported by the support columns 731. An electric cylinder 732 is fixedly arranged in the middle of the side of the U-shaped fixing frame 73 away from the workbench 1. The output end of the electric cylinder 732 penetrates through the U-shaped fixing frame 73 and is fixedly connected to the first adjusting plate 75. The telescopic movement of the electric cylinder 732 facilitates the movement of the first adjusting plate 75 in the chute 74 and the guide groove 23.

[0047] In order to make the device applicable to the flocking of Zhang satin with different width dimensions, as Figure 6 shown, two second threaded rods 24 are rotatably arranged on the front and rear sides inside the support box body 2. The threads on both sides of the second threaded rods 24 are opposite. Two adjusting blocks 25 are symmetrically threadedly connected to both sides of the second threaded rods 24. A second adjusting plate 26 is arranged on the top of the adjusting block 25. The second adjusting plate 26 has a clearance fit with the inner top wall of the support box body 2. A fourth motor 27 is fixedly arranged outside the support box body 2. The output end of the fourth motor 27 is fixedly connected to one end of the second threaded rod 24. The fourth motor 27 is a forward and reverse motor. By controlling the forward and reverse rotation of the second threaded rod 24 through the fourth motor 27, the two adjusting blocks 25 move towards or away from each other, driving the two second adjusting plates 26 to move towards or away from each other. When the two second adjusting plates 26 move away from each other to both ends, the two second adjusting plates 26 block the through holes 21 at both ends. At this time, it can be applicable to the flocking of Zhang satin with a narrower size. When the two second adjusting plates 26 move towards the middle, it can be applicable to the flocking of Zhang satin with a wider size.

[0048] When the textile Zhang satin flocking device in this embodiment is in use, the preliminarily woven Zhang satin fabric moves to the top of the support box body 2 through a plurality of fabric guide rollers 3 and the right transmission roller 6. By means of a vacuum pump, negative pressure is generated inside the support box body 2, so that the Zhang satin fabric is always closely attached to the top of the support box body 2;

[0049] By controlling the first threaded rod 53 to rotate through the first motor 54, and driving the moving block 55 to move along the guide rod 52, the cutting knife 58 makes a reciprocating motion, and the Zhang satin fabric is subjected to flocking treatment;

[0050] The rotation of the cloth winding roller 4 is controlled by the second motor 12, so that the Zhang satin after velvet cutting is wound and collected on the cloth winding roller 4;

[0051] When the tail end of the Zhang satin approaches the cutting device 5, the first gear 14 is controlled to rotate by the third motor 13. The first gear 14 drives the second gear 711 meshing with it to rotate, thereby driving the C-shaped fixed frame 73 to rotate, so that the C-shaped fixed frame 73 rotates counterclockwise by 90° to the highest point;

[0052] The first adjusting plate 75 is slid from the chute 74 to the guide groove 23 by the electric cylinder 732 to block the through hole 21 exposed at the tail end of the Zhang satin fabric, so that a negative pressure environment is always maintained inside the support box body 2;

[0053] When velvet cutting is to be performed on Zhang satins of different width dimensions, the second threaded rod 24 is controlled to rotate forward and backward by the fourth motor 27, so that the two adjusting blocks 25 move towards or away from each other, driving the two second adjusting plates 26 to move towards or away from each other. When the two second adjusting plates 26 move away from each other to both ends, the two second adjusting plates 26 block the through holes 21 at both ends. At this time, velvet cutting of a relatively narrow-sized Zhang satin can be applied. When the two second adjusting plates 26 move towards the middle, velvet cutting of a relatively wide-sized Zhang satin can be applied at this time.

[0054] Embodiment 2

[0055] On the basis of Embodiment 1, this embodiment provides a Zhang satin velvet cutting process for textile, including the following steps:

[0056] The preliminarily woven Zhang satin fabric enters above the support box body 2 through a plurality of fabric guide rollers 3 and the right transmission roller 6;

[0057] Adjust the distance between the two second adjusting plates 26 according to the width of the Zhang satin fabric;

[0058] A negative pressure is generated inside the support box body 2 by the vacuum pump connected to the connection hole 22, so that the Zhang satin fabric is always flat against the top of the support box body 2;

[0059] The Zhang satin fabric is velvet cut by the cutting knife 58 through the reciprocating movement of the cutting device 5;

[0060] The cloth winding roller 4 is controlled to rotate by the second motor 12, and the Zhang satin fabric after velvet cutting is wound and collected on the cloth winding roller 4 through the left transmission roller 6;

[0061] When the tail end of the Zhang satin fabric reaches the right edge of the support box body 2, the adjustment assembly 7 is rotated counterclockwise by 90°, and the first adjusting plate 75 is controlled to move leftward by the electric cylinder 732 to cover the through hole 21 exposed at the tail end of the Zhang satin fabric until all the Zhang satin fabric is wound and collected on the cloth winding roller 4.
