[0027] As a preferred technical scheme, the linkage assembly includes two second protrusions 43 arranged on one side of the first blade 37 and the second blade 38 respectively, the second fixed seat 45 is arranged on the side plate 8, the two connecting rods 41 are reversely rotatably connected in the second fixed seat 45, the fourth gear 44 is arranged on one side of each of the two connecting rods 41, the two fourth gears 44 are engaged with each other, the second sliding hole 42 is arranged on each of the two connecting rods 41, and the two second protrusions 43 and the two second sliding holes 42 are in one-to-one correspondence and slidingly abut each other, the first limiting piece is arranged on the other side of the second blade 38, specifically, in the sliding process of the first blade 37, the second protrusion 43 on the first blade 37 slidingly abuts the corresponding second sliding hole 42 to drive the corresponding connecting rod 41 to rotate, the other connecting rod 41 is reversely rotated through the engagement between the two fourth gears 44, and the second protrusion 43 on the second blade 38 slidingly abuts the second sliding hole 42 on the other connecting rod 41 to make the second blade 38 and the first blade 37 slide in the opposite direction synchronously, so as to open and close the first blade 37 and the second blade 38 to cut the two single-layer cloths.

[0028] As a preferred technical scheme, the first limiting piece comprises a first limiting rod 39 vertically and fixedly arranged at the bottom of the top plate 7, the other side of the second blade 38 is fixedly connected with a connecting block 40, a through hole is formed in the connecting block 40, and the first limiting rod 39 is vertically and slidingly connected in the through hole. Specifically, the inner wall of the second sliding hole 42 provides a pushing force to the second protrusion 43. Since the first limiting rod 39 is vertically and fixedly arranged, the second blade 38 is guided and limited by the first limiting rod 39 through the connecting block 40, and can only slide in the vertical direction, so that the sliding track of the second blade 38 is linear and cannot deviate.

[0029] As a preferred technical scheme, the transmission assembly comprises a moving block 27, a frame 18, a half gear 16, a supporting block 23, and a third gear 4 engaged with the first gear 2. The top of the first blade 37 is fixedly connected with the bottom of the moving block 27. A rotating rod 15 is arranged between the half gear 16 and the third gear 4. Two racks 17 are symmetrically arranged in the frame 18 and engaged with the half gear 16. The supporting block 23 is horizontally and slidingly connected to one side of the frame 18. The top of the supporting block 23 is in abutting engagement with the bottom of the moving block 27. A limiting block 34 is horizontally and slidingly connected to the side plate 8. A second telescopic column 36 is arranged between the limiting block 34 and the side plate 8. A second spring 35 is sleeved on the second telescopic column 36. The end of the limiting block 34 away from the second spring 35 is obliquely arranged towards the moving block 27. The moving block 27 is in abutting engagement with the limiting block 34. A second limiting piece is arranged between the frame 18 and the top plate 7. Specifically, the third gear 4 is rotatably connected to one side of the rack 1 close to the first gear 2. The rotation of the first gear 2 drives the rotation of the third gear 4. The third gear 4 drives the rotation of the half gear 16 through the rotating rod 15. When the thickness of the cloth wound on the first glue-coated roller 12 reaches the preset value, the third gear 4 drives the half gear 16 to rotate one circle. The half gear 16 is engaged with one of the racks 17 first, driving the frame 18 to move upwards. After rotating half a circle, the half gear 16 is engaged with the other rack 17, driving the frame 18 to move downwards, completing one round trip. During the movement of the frame 18 driving the supporting block 23 to move upwards, the top of the supporting block 23 provides an upward pushing force to the moving block 27, causing the moving block 27 to move upwards. The moving upwards of the moving block 27 is in abutting engagement with the limiting block 34. The moving block 27 provides a horizontal pushing force to the obliquely arranged end of the limiting block 34. When the moving block 27 drives the first blade 37 to move to the standby station, the limiting block 34 is horizontally and reversely moved to the bottom of the moving block 27 through the elastic deformation of the second spring 35. At this time, the limiting block 34 provides an upward supporting force to the moving block 27, causing the first spring 29 to be in a stored energy completion state.

[0030] As a preferred technical scheme, the second limiting piece comprises two second limiting rods 19 vertically and fixedly arranged at the bottom of the top plate 7, two first sliding grooves 20 are symmetrically arranged in the frame 18, and the two second limiting rods 19 and the two first sliding grooves 20 are in one-to-one sliding connection. Specifically, through the sliding fit between the second limiting rod 19 and the first sliding groove 20, the frame 18 can only move linearly in the vertical direction, so as to avoid the horizontal displacement between the frame 18 and the half gear 16, which may cause the frame 18 to fall off and damage the device.

[0031] As a preferred technical scheme, the frame 18 is provided with a first sliding rod 25 on the side close to the support block 23, a third spring 26 is sleeved on the first sliding rod 25, the two ends of the third spring 26 are fixedly connected with the frame 18 and the support block 23 respectively, a second sliding groove 24 is horizontally arranged in the support block 23, the first sliding rod 25 is in sliding connection with the first sliding groove 20, a fixed block 22 is fixedly connected to the support block 23, a stop block 21 is fixedly connected to the bottom of the top plate 7, the fixed block 22 is in abutting fit with the stop block 21, and the bottom of the stop block 21 is inclinedly arranged towards the fixed block 22. During the upward movement of the support block 23, when the moving block 27 drives the first blade 37 to be located at the standby station, the fixed block 22 is pressed by the stop block 21, thereby driving the support block 23 to move horizontally along the length direction of the first sliding rod 25. At this time, the third spring 26 is compressed, and the upward pushing force of the support block 23 on the moving block 27 is eliminated. When the frame 18 drives the support block 23 to move downward, the support block 23 moves horizontally in the opposite direction through the third spring 26. Preferably, the end of the support block 23 close to the moving block 27 is inclinedly arranged towards the first blade 37. During the downward movement of the support block 23, the end of the moving block 27 close to the support block 23 gives the support block 23 a horizontal pressing force, so as to avoid the moving block 27 from hindering the downward movement of the support block 23.

[0032] As a preferred technical scheme, the trigger assembly comprises a first fixing seat 30 fixedly arranged on the side plate 8, a swing rod 31 rotationally connected in the first fixing seat 30, a first protrusion 33 arranged on one side of the limiting block 34, a first sliding hole 32 arranged on the swing rod 31, and the first protrusion 33 is in sliding abutment with the first sliding hole 32. Specifically, the first glue applying roller 12 is always winding the fabric, and the thickness of the fabric wound on the first glue applying roller 12 is constantly increasing. When the thickness of the fabric wound on the first glue applying roller 12 reaches a certain value, the fabric wound on the first glue applying roller 12 abuts against the swing rod 31, the fabric wound on the first glue applying roller 12 gives the swing rod 31 a horizontal pushing force, the first protrusion 33 is given a horizontal pushing force through the first sliding hole 32, the limiting block 34 moves horizontally towards the side plate 8, when the thickness of the fabric wound on the first glue applying roller 12 reaches a preset value, the supporting force of the limiting block 34 on the moving block 27 is released, at this time, the first spring 29 releases energy, pushes the first blade 37 to move downward rapidly, through the linkage assembly, the first blade 37 drives the second blade 38 to slide reversely and synchronously to cut the two single-layer fabrics, the two single-layer fabrics are passively cut, and the length of the double-faced fabric to be cut can be determined.

[0033] Working principle: the first blade 37 is displaced upward by a small distance, so that the double-faced fabric can pass between the first blade 37 and the second blade 38, and the double-faced fabric is pre-cut by a small part, and the two layers of the double-faced fabric are fixed on the first glue roller 12 and the second glue roller 13 respectively. At the outlet of the channel, the connecting line between the two layers of the double-faced fabric is cut by the transversely stretched electric heating wire 11, so as to realize the layering of the double-faced fabric with a width larger than the diameter of the traditional cutting blade, avoid the problems of cutting the fabric and generating burrs, and start the motor 5 to drive the second shaft 46 to rotate, so that the first shaft 14 and the second shaft 46 rotate in opposite directions through the meshing between the first gear 2 and the second gear 3, so as to realize the winding of the single layer fabric in the clockwise and counterclockwise directions by the first glue roller 12 and the second glue roller respectively. At the same time, the rotation of the first gear 2 drives the rotation of the third gear 4, and the third gear 4 drives the rotation of the half gear 16 through the rotating rod 15. When the thickness of the fabric wound on the first glue roller 12 reaches the preset value, the third gear 4 drives the half gear 16 to rotate one circle, and the half gear 16 meshes with one of the racks 17 first, drives the frame 18 to move upward, and in the process of moving the support block 23 upward by the frame 18, the top of the support block 23 gives the upward pushing force to the moving block 27, so that the moving block 27 moves upward, and the process of moving the moving block 27 upward is in abutment with the limiting block 34, and the moving block 27 gives the horizontal pushing force to the one end of the limiting block 34 arranged obliquely, so that the limiting block 34 moves to the bottom of the moving block 27 through the elastic deformation of the second spring 35. At this time, the limiting block 34 gives the upward supporting force to the moving block 27, so that the first spring 29 is in the energy storage completion state. In the process of moving the support block 23 upward, when the moving block 27 drives the first blade 37 to be located in the standby position, the fixed block 22 is pressed by the stop block 21, drives the support block 23 to move horizontally along the length direction of the first slide rod 25, at this time, the third spring 26 is compressed, and the upward pushing force of the support block 23 to the moving block 27 is eliminated. After the half gear 16 rotates half a circle, the half gear 16 meshes with the other rack 17, drives the frame 18 to move downward, and the frame 18 drives the support block 23 to move downward through the elastic deformation of the third spring 26, and the support block 23 moves horizontally in the opposite direction, which can be prepared for the next cutting. The first glue roller 12 is always winding the fabric, and the thickness of the fabric wound on the first glue roller 12 is increasing, and when it increases to a certain value, the fabric wound on the first glue roller 12 abuts against the swing rod 31, and the fabric wound on the first glue roller 12 gives the horizontal pushing force to the swing rod 31 through the first slide hole 32, so that the first protrusion 33 gives the horizontal pushing force to the limiting block 34 through the first slide hole 32, so that the limiting block 34 moves horizontally toward the side plate 8. When the thickness of the fabric wound on the first glue roller 12 reaches the preset value,The support force of the limiting block 34 on the moving block 27 is released, at this time, the first spring 29 releases energy, pushes the first blade 37 to move downward rapidly, through the second protrusion 43 on the first blade 37 slidingly abutting the corresponding second sliding hole 42, drives the corresponding connecting rod 41 to rotate, through the meshing between the two fourth gears 44, makes the other connecting rod 41 reverse rotation, through the sliding abutment between the second protrusion 43 on the second blade 38 and the second sliding hole 42 on the other connecting rod 41, makes the first blade 37 drive the second blade 38 to slide reversely and synchronously, cuts the two single-layer fabrics, realizes the passive cutting of the two single-layer fabrics, and can cut the two single-layer fabrics according to the length of the double-faced fabric to be cut.

[0034] The foregoing merely illustrates some exemplary embodiments of the present application, no doubt numerous modifications can be made by those skilled in the art without departing from the spirit and scope of the present application. Therefore, the above description is in essence illustrative, and should not be understood as limiting the scope of the present application.
