The first cylinder 2 is fixed on the upper surface of the base 1, and the piston rod of the first cylinder 2 extends vertically upward. The mounting rod 3 is a horizontally arranged rectangular rod-shaped structure, and the mounting rod 3 is fixed to the end of the piston rod of the cylinder. The side wall of the mounting rod 3 is provided with a slide groove 31, and the side wall of the mounting rod 3 is provided with a connecting groove 32 connected to the slide groove 31. The vertical rod 4 is a vertically arranged rectangular rod-shaped structure, and the vertical rod 4 is arranged at the bottom of the mounting rod 3. The pressing roller 5 is a round roller-shaped structure, and the pressing roller 5 is rotatably connected to the side wall of the vertical rod 4.

[0032] The cutting assembly 6 is mounted on the mounting rod 3 and is used for cutting lace. The cutting assembly 6 includes a slide rail 61, a linear motor 62, a second cylinder 63 and a cutting head 64. The slide rail 61 is a horizontally arranged rectangular rod-shaped structure, and the slide rail 61 is slidably connected to the inner wall of the slide groove 31. The linear motor 62 is a linear motor 62 commonly used in the prior art and applicable to the present embodiment. The linear motor 62 is mounted on the slide rail 61 and is used to move on the slide rail 61. The second cylinder 63 is fixed at the bottom of the linear motor 62, and the piston rod of the second cylinder 63 extends vertically downward. The cutting head 64 is a cutting head 64 commonly used in the prior art and applicable to the present embodiment, and the cutting head 64 is fixed to the end of the piston rod of the cylinder.

[0033] The limit assembly 7 is mounted on the mounting rod 3 and is used to limit the position of the slide rail 61. The limit assembly 7 includes a threaded rod 71, a sleeve 72 and a rotating block 73. The threaded rod 71 is a horizontally arranged rod-shaped structure, fixed on the side wall of the slide rail 61, and slidably connected with the connecting groove 32. The sleeve 72 is sleeved on the threaded rod 71 and threadedly connected with the threaded rod 71, and the axis of the sleeve 72 coincides with the axis of the threaded rod 71. The rotating block 73 is a hexagonal block structure, fixedly sleeved on the sleeve 72, and the axis of the rotating block 73 coincides with the axis of the sleeve 72.

[0034] When the lace needs to be cut, the staff places the lace on the base 1 and controls the mounting rod 3 to move downward through the first cylinder 2, so that the pressing roller 5 presses down against the lace, and then moves the slide rail 61 to a suitable position and rotates the sleeve 72 through the rotating block 73, so that the sleeve 72 presses against the side wall of the mounting rod 3, thereby limiting the sliding of the slide rail 61 in the slide groove 31, and moves the cutting head 64 downward through the second cylinder 63 and moves the cutting head 64 through the linear motor 62 to cut the lace, which facilitates the adjustment of the position of the cutting head 64, thereby improving the cutting efficiency and practicality of the cutting device.

[0035] In order to further reduce the probability of the sliding rail 61 moving when the sliding rail 61 is cutting, a rubber sheet 8 is fixed to one end of the sleeve 72 close to the mounting rod 3, and the threaded rod 71 passes through the rubber sheet 8 and is loosely fitted. One end of the sleeve 72 is pressed against the side wall of the rubber sheet 8. The rubber sheet 8 is made of rubber material, and its surface has a large friction coefficient. When the staff turns the block 73 to rotate the sleeve 72, the sleeve 72 is fitted with the side wall of the mounting rod 3 and pressed against the rubber sheet 8, thereby increasing the friction between the sleeve 72 and the mounting rod 3, thereby further reducing the probability of the sliding rail 61 moving when the sliding rail 61 is cutting.

[0036] In order to facilitate the staff to operate the limit assembly 7, a plurality of assisting rods 9 are fixedly connected to the side wall of the rotating block 73, and the plurality of assisting rods 9 are evenly distributed about the axis of the threaded rod 71.

A spring 11 is arranged in the sleeve 10, and the upper end of the spring 11 is fixed to the inner top wall of the sleeve 10, and the lower end of the spring 11 is fixed to the upper end of the vertical rod 4. Under the elastic force of the spring 11, the vertical rod 4 drives the pressing roller 5 downward to press against the lace, thereby increasing the buffer between the pressing roller 5 and the lace and reducing the probability of wrinkles or even damage caused by the pressing roller 5 directly pressing against the lace through the first cylinder 2.

[0038] In order to prevent the vertical rod 4 from falling off the sleeve 10 downward, a limit groove 101 is opened on the inner wall of the sleeve 10, and a limit block 12 is fixed to the side wall of the vertical rod 4 which is slidably connected to the limit groove 101. The limit block 12 is slidably connected in the limit groove 101, which limits the moving position of the vertical rod 4, thereby preventing the vertical rod 4 from falling off the sleeve 10 downward, which is conducive to the normal use of the clamping roller 5.
