DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] The present invention provides Figure 1-7 The sole polishing device for leather shoe production shown in the figure comprises a base 001, and a fixing plate 101 is symmetrically installed above the base 001; The driving assembly 002 disposed between the two sets of fixed plates 101 includes a servo motor 201, the servo motor 201 is fixedly connected to one set of fixed plates 101, a screw rod 202 is rotatably connected between the two sets of fixed plates 101, a slide rod 204 is fixedly connected between the two sets of fixed plates 101, a moving seat 203 is screwed onto the screw rod 202, and the moving seat 203 is connected through the slide rod 204; By starting the servo motor 201 , the servo motor 201 can drive the screw rod 202 to rotate, so that the screw rod 202 drives the upper moving seat 203 to slide along the slide bar 1 204 , and the slide bar 1 204 can ensure the stable sliding of the moving seat 203 .

[0022] The fixing assembly 003 disposed between the two sets of fixing plates 101 includes a guide rod 305, which is installed between the two sets of fixing plates 101, and a sliding seat 304 is slidably connected to the guide rod 305, and the sliding seat 304 and the moving seat 203 are in the same vertical horizontal plane; Through the cooperation between the sliding seat 304 and the guide rod 305 , the sliding seat 304 can stably slide between the two sets of fixed plates 101 .

[0023] The grinding assembly 004 disposed above the base 001 includes a trapezoidal plate 410 , which is symmetrically mounted above the base 001 , and a middle area of ​​the trapezoidal plate 410 is in a raised state compared to positions on both sides.

[0024] The protrusions of the trapezoidal plates 410 are symmetrical, so that a larger space exists between the two groups of trapezoidal plates 410, so that the sole can change direction at this place.

[0025] Furthermore, in the above structure, the driving assembly 002 also includes a sleeve 205, which is rotatably connected above the movable seat 203, and a gear 206 is fixedly sleeved on the sleeve 205. A rack 207 is installed between the two sets of fixed plates 101, and the convex tooth part of the rack 207 is located at the raised position of the two sets of trapezoidal plates 410, and the rack 207 is meshed with the gear 206.

[0026] Through the gear 206 on the sleeve 205, the sleeve 205 is continuously moved, and finally the gear 206 and the rack 207 are meshed, so that the sleeve 205 rotates, and when the rotation is in progress, the rack is in a raised position between the two sets of trapezoidal plates 410.

[0027] Furthermore, in the above structure, limiting grooves 208 are symmetrically provided on the inner wall of the sleeve 205, a docking shaft 209 is connected through the sleeve 205, limiting blocks 210 are symmetrically installed on the docking shaft 209, and the limiting blocks 210 are slidably connected to the corresponding limiting grooves 208, and a spring 211 is sleeved on the docking shaft 209.

[0028] Through the cooperation between the limiting block 210 and the limiting groove 208 , the position of the docking shaft 209 can be limited in the sleeve 205 , and the docking shaft 209 can only move up and down but cannot rotate.

[0029] Furthermore, in the above structure, the fixing assembly 003 also includes a sole template 301, which is installed above the docking shaft 209, and both sides of the spring 211 are respectively fitted between the sole template 301 and the sleeve 205.

[0030] By pushing the spring 1 211, the docking shaft 209 slides along the sleeve 205, so that the sole template 301 has an upward force, and the sole template 301 can be replaced according to the size of the sole, and the sole template 301 can avoid excessive grinding.

[0031] Furthermore, in the above structure, a second fixing plate 302 is rotatably connected below the sliding seat 304 , and a plurality of positioning blocks 303 are installed below the second fixing plate 302 , and the positioning blocks 303 are fitted to the upper part of the sole template 301 .

[0032] By moving the sole template 301 upward, the upper part of the sole can fit with the groups of positioning blocks 303 below the second fixing plate 302, thereby completing the fixation of the sole, and this method can ensure that soles of various thicknesses can be effectively fixed.

[0033] Furthermore, in the above structure, the grinding assembly 004 includes a connecting plate 401, and a sliding rod 402 is symmetrically installed on one side of the connecting plate 401, and the sliding rod 402 is connected to the inner wall of the trapezoidal plate 410 through the connecting plate 401, and the connecting plate 401 is provided with multiple groups on one side of the inner wall of the trapezoidal plate 410, and a spring 403 is sleeved on the sliding rod 402, and the two sides of the spring 403 are respectively fitted with the trapezoidal plate 410 and the connecting plate 401.

[0034] The spring 2 403 can be used to enable the connecting plate 401 to drive the slide bar 2 402 to maintain the moving position of the trapezoidal plate 410, so that the connecting plate 401 always has a force to one side, thereby achieving the effect of grinding in contact with the side of the sole, and the setting of the two sets of slide bars 402 can ensure the stable position of the trapezoidal plate 410.

[0035] Furthermore, in the above structure, a bolt 404 is fixedly connected to one side of the connecting plate 401, and the bolt 404 is connected through the trapezoidal plate 410, a nut 405 is threaded on the bolt 404, and the nut 405 is fitted with the outer side of the trapezoidal plate 410, and a motor 406 is installed on the side of the connecting plate 401 away from the sliding rod 402, and a toothed pulley 407 is installed on the output end of the motor 406.

[0036] By rotating the nut 405 along the bolt 404, the gap between the connecting plate 401 and the trapezoidal plate 410 is changed, so that the spring 2 403 is squeezed, so that the rebound distance is reduced and the required rebound force is increased. In this way, the position of each group of connecting plates 401 can be adjusted individually to achieve corresponding grinding position adjustment according to different shoe shapes and material textures.

[0037] Furthermore, in the above structure, a grinding cylinder 408 is rotatably connected to one side of the connecting plate 401 close to the motor 406, and each group of grinding cylinders 408 is axially connected to a toothed pulley 407, a toothed belt 409 is installed between each group of toothed pulleys 407, and the grinding cylinders 408 on one side of the two groups of trapezoidal plates 410 are arranged opposite to each other, and the two groups of grinding cylinders 408 are at the same horizontal position as the sole template 301.

[0038] The motor 406 can drive the grinding cylinder 408 to rotate. Since a spring 403 is separately provided on one side of each group of grinding cylinders 408, the grinding cylinder 408 can automatically adapt to the shape of the side surface of the sole and perform grinding. The toothed belt 409 cooperates with the toothed pulley 407 to realize the simultaneous rotation of multiple groups of grinding cylinders 408. The use of this structure is not affected by the individual adjustment of the position of each group of grinding cylinders 408, thereby ensuring normal grinding.

[0039] A method for using a sole polishing device for leather shoe production includes the above sole polishing device for leather shoe production, and the specific processing steps are as follows: S1: The shoe sole to be polished is placed on the sole template 301 and fixed by contacting with the second fixing plate 302. At this time, the servo motor 201 of the driving assembly 002 drives the screw 202 to rotate, so that the screw 202 drives the moving seat 203 to move, so that the shoe sole moves along the polishing cylinder 408 between the two sets of trapezoidal plates 410; S2: At this time, the grinding cylinder 408 is driven by the motor 406 to rotate, and the grinding cylinder 408 is attached to the side of the sole under the action of the spring 2 403, so that the grinding cylinder 408 is attached to the side of the sole to grind; S3: As the driving component 002 continues to move, the fixing component 003 drives the sole to rotate as a whole through the cooperation of the gear 206 and the rack 207, so that the front and rear sides of the sole can be polished to avoid polishing dead corners.

[0040] In further optimization of the above embodiment, in order to save resources and reduce processing costs, like Figure 1-7As shown, by pressing the sole template 301 downward, the spring 1 211 is squeezed, and the sole is placed above the sole template 301, and the sole template 301 is loosened. At this time, the spring 1 211 drives the sole template 301 to reset, so that the positioning block 303 under the fixing plate 2 302 fits with the upper part of the sole, thereby completing the entire fixation, and according to the shape and material of the sole to be polished, the nut 405 is rotated to make the nut 405 drive the bolt 404 to move, so that the connecting plate 401 drives the position of the polishing cylinder 408 to change, and at this time, the servo motor 201 is started, so that the screw rod 202 drives the moving seat 203 to move , so that the sole contacts the grinding cylinder 408 for grinding, and with the continuous movement, through the cooperation of the gear 206 and the rack 207, the sole template 301 drives the sole to rotate as a whole, and the grinding of the front and rear sides of the sole is completed during the rotation, and the reciprocating movement can complete the overall grinding, and the cooperation between the sole template 301 and the sole can avoid the excessive grinding of the grinding cylinder 408. Through this structure, the quality and efficiency of the sole grinding can be effectively improved, and the grinding of soles of different shapes and materials can be achieved through the adjustment of the grinding cylinder 408, thereby improving the adaptability of the device.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
