DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0043] Embodiment 1

[0044] Refer to Figures 1-4 , a canvas cutting device for shoes, including a main body assembly 1. The main body assembly 1 includes: a cutting table 11 with chutes opened on both sides thereof, and a bracket 12 is slidably connected in the chutes; a cutting knife 13 is slidably connected to the bracket 12; a flattening assembly 2 is arranged on the cutting table 11. The flattening assembly 2 includes: a rotating rod 21 rotatably connected to the front side of the cutting table 11 and extending into the cutting table 11; a handwheel 211 arranged at one end of the rotating rod 21 outside the cutting table 11; a T-shaped steering gear 22, the output shaft of which is fixedly connected to the other end of the rotating rod 21; a reverse lead screw 23 rotatably connected to the inside of the cutting table 11 and fixedly connected to the output shafts on both sides of the T-shaped steering gear 22; a threaded block 24 symmetrically and threadedly connected to the outside of the reverse lead screw 23; a support rod 25 fixedly connected to the top of the threaded block 24, and two through grooves for the support rod 25 to move are opened on the cutting table 11; a fixing mechanism 26 is arranged on the top of the support rod 25. The fixing mechanism 26 includes: a support plate 261 fixedly connected to the top of the support rod 25; a sliding rod 262 passing through and slidably connected to the support plate 261; a pressing plate 263 arranged at the bottom of the sliding rod 262; a spring 264 sleeved outside the sliding rod 262 and located between the support plate 261 and the pressing plate 263; a pull rod 265 arranged at the top of the sliding rod 262. Multiple groups of the sliding rod 262 and the spring 264 are symmetrically arranged.

[0045] In use, the staff places the canvas to be cut on the upper surface of the cutting table 11 and flattens the edges by means of the flattening assembly 2: The staff rotates the handwheel 211, and the handwheel 211 drives the rotating rod 21 to rotate. The torque of the rotating rod 21 is reversed by the T-shaped steering device 22, so that the reverse lead screws 23 on both sides of the T-shaped steering device 22 rotate. The threaded blocks 24 threadedly connected to the reverse lead screws 23 drive the support rods 25 to approach or depart from each other according to the different rotation directions of the reverse lead screws 23. The support rods 25 drive the fixing mechanisms 26 to approach or move away from each other, facilitating the adjustment of the steering and rotation amplitude of the handwheel 211 according to the width of the canvas. After the adjustment according to the canvas width is completed, at this time, the fixing mechanisms 26 are located on both sides of the canvas to fix the canvas: The staff pulls up the pull rod 265, and the pull rod 265 drives the sliding rod 262 and the pressing plate 263 to move upward. At this time, the compression spring 264 is compressed. The handwheel 211 is slightly rotated so that the fixing mechanism 26 and the pressing plate 263 move above the canvas. At this time, the pull rod 265 is released, and the elastic force of the spring 264 pushes the pressing plate 263 downward until it is close to the upper surface of the canvas. The spring 264 is telescopic, facilitating the fixation of canvases of different thicknesses. After the canvas is fixed, the bracket 12 can move along the sliding grooves on both sides of the cutting table 11, and the cutting knife 13 slides on the bracket 12. The cutting knife 13 can move flexibly, facilitating the cutting of the canvas into different shapes. Multiple groups of sliding rods 262 and springs 264 are provided, so that the pressing plates 263 are on the same horizontal line, preventing the pressing plates 263 from tilting during the up and down movement and affecting the normal flattening effect of the pressing plates 263.

[0046] Embodiment 2

[0047] On the basis of Embodiment 1, an auxiliary function is added.

[0048] Refer to Figures 1-4 , a limiting mechanism 27 is provided on the top of the support plate 261. The limiting mechanism 27 includes: a vertical plate 271 provided on the top of the support plate 261; a groove 272 opened on the opposite surfaces of the vertical plate 271; a convex block 273 provided on the opposite surfaces of the vertical plate 271 and located inside the groove 272; a guide rod 274, one end of which is hinged to the top of the pull rod 265 and the other end of which is slidably connected to the groove 272. The height of the convex block 273 is smaller than the length of the sliding rod 262. An accordion shell 251 is provided on the through groove opened on the cutting table 11 for the support rod 25 to move.

[0049] The limiting mechanism 27 is limited when the pull rod 265 is lifted upward: when the pull rod 265 is lifted upward, the guide rod 274 hinged at the top of the pull rod 265 slides upward at the bottom end of the groove 272, and when it slides to the side between the groove 272 and the protrusion 273, the bottom of the guide rod 274 rotates along the position where it is hinged to the pull rod 265, thereby driving the pull rod 265 to move up and down, and the guide rod 274 continues to slide upward in the heart-shaped groove 272 until the top of the guide rod 274 slides to the upper part of the groove 272, and the top of the guide rod 274 is hit by the top of the protrusion 273. The guide rod 274 drives the pull rod 265 to be continuously raised, which makes it convenient for the staff to adjust the position of the fixing mechanism 26. The staff does not need to lift the pull rod 265 all the time. When the limit needs to be released, the pull rod 265 is continuously pulled upward. The pull rod 265 drives the guide rod 274 to disengage from the top of the protrusion 273 and slide downward along the area between the groove 272 and the protrusion 273 until the bottom of the guide rod 274 returns to the bottom of the groove 272. At this time, the pull rod 265 is not subject to tension, and the pressure plate 263 can fix the canvas. The height of the protrusion 273 is smaller than the length of the slide rod 262, which facilitates the movement of the guide rod 274 in the groove 272 to prevent it from getting stuck. The accordion shell 251 expands and contracts with the movement of the support rod 25, shielding the exposed through slot for the support rod 25 to move, preventing canvas or debris from entering the reverse screw rod 23 through the through slot and affecting the normal use of the device.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
