Description

Technical Field

[0001] This utility model relates to the field of shoe processing technology, specifically to a shoelace cutting device for shoe production and processing. Background Technology

[0002] Shoes are an indispensable means of transportation in people's daily lives, and most shoes are tied with shoelaces during use. During the production process, after the shoelaces are woven, they need to be cut to a certain length according to the shoe body.

[0003] However, existing shoelace cutting devices used in shoe manufacturing still have the following drawbacks during use:

[0004] 1. Existing cutting devices cannot guarantee a high degree of coordination between the feeding and cutting frequency of shoelaces, which easily leads to uneven cutting. In addition, when cutting shoelaces of different lengths, the length adjustment operation is cumbersome and the accuracy needs to be improved.

[0005] 2. Existing cutting devices heat-melt the ends of the shoelaces after cutting, which makes the shoelace ends prone to splitting, which is not conducive to subsequent processing. Some heat-melting methods using the cutting blade will keep the cutting blade heated, which will reduce the hardness of the cutting blade and shorten its service life. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] A preferred embodiment of the present invention, a shoelace cutting device for shoe manufacturing, will be described in detail below, such as... Figures 1-2 As shown, a shoelace cutting device for shoe manufacturing includes a horizontal plate 1 and a support leg 2. The support leg 2 is fixedly installed at the bottom end of the horizontal plate 1. Mounting seats 3 are fixedly installed on the front and rear sides of the top right side of the horizontal plate 1. A conveying assembly 4 is arranged between the mounting seats 3 and inside the right side of the horizontal plate 1. Mounting frames 5 are fixedly installed on the front and rear sides of the top middle part of the horizontal plate 1. A cutting assembly 6 is arranged between the mounting frames 5. A cutting groove 7 is opened at the top middle part of the horizontal plate 1. A heating rod 8 is fixedly installed below the cutting groove 7 inside the horizontal plate 1.

[0031] A roller 9 is inserted into the right side of the horizontal plate 1. The roller 9 is used to connect to the winding cylinder with shoelaces. A conveyor belt 10 is connected to the top of the left side of the horizontal plate 1. The conveyor belt 10 is used to transport and collect the cut shoelaces.

[0032] Furthermore, such as Figures 2-4 As shown, the conveying assembly 4 includes a pressing conveying roller 41. The pressing conveying roller 41 is rotatably connected between the left sides of the mounting base 3. The pushing roller group 42 is rotatably connected between the mounting base 3 and inside the horizontal plate 1, and the pushing roller group 42 is located to the right of the pressing conveying roller 41. The rear end of the rear mounting base 3 is fixedly installed with a motor 43, and the motor 43 is connected to the pressing conveying roller 41. The front sides of the vertically arranged pushing roller groups 42 are all fixedly installed with gear groups 44, and the gear groups 44 mesh with each other. The pressing conveying roller 41 and the upper pushing roller group 42 are alternately connected by a transmission belt 45. The front side of the pressing conveying roller 41 is fixedly installed with a fixed pulley 46.

[0033] Furthermore, such as Figures 4-10As shown, the cutting assembly 6 includes a rotating shaft 61. The rotating shaft 61 is rotatably connected between the top of the mounting bracket 5. A turntable 62 is fixedly installed at one adjacent end of the rotating shaft 61. An eccentric shaft 63 is eccentrically fixedly installed between the turntables 62. A sliding plate 64 is placed between the turntables 62, and the sliding plate 64 wraps around the outside of the eccentric shaft 63. The eccentric shaft 63 is slidably connected within the sliding plate 64. A cutter 65 is fixedly installed at the center of the bottom of the sliding plate 64. The cutter 65 is vertically aligned with the cutting groove 7.

[0034] A limiting plate 66 is fixedly installed in the middle of the mounting bracket 5, and the cutter 65 passes through the middle of the limiting plate 66 and is slidably connected to the limiting plate 66. A movable pulley 67 is slidably connected to the outer side of the front rotating shaft 61. A belt 68 is connected between the movable pulley 67 and the fixed pulley 46. Springs 69 are fixedly connected to the front rotating shaft 61 at both ends of the movable pulley 67. The movable pulley 67 is composed of two conical wheels that are slidably connected in a staggered manner, and the conical surfaces of the conical wheels are opposite each other. Therefore, the transmission diameter of the movable pulley 67 can be adjusted by the relative and separation movement of the two conical wheels of the movable pulley 67.

[0035] A transmission ratio adjustment component 610 is provided between the top of the front mounting base 3 and the belt 68. The transmission ratio adjustment component 610 includes an inclined pressure rod 6101. The top of the front mounting base 3 is hinged to the inclined pressure rod 6101. The side of the inclined pressure rod 6101 away from the mounting base 3 is rotatably connected to a roller 6102. A fastening hinge seat 6103 is provided at the hinge point between the inclined pressure rod 6101 and the mounting base 3. The inclined rotation of the inclined pressure rod 6101 is limited by the fastening hinge seat 6103.

[0036] The working principle of this utility model is as follows:

[0037] Before cutting, the winding cylinder with shoelaces is attached to the outside of the insertion roller 9 by first pulling out the insertion roller 9, so that the winding cylinder can rotate around the insertion roller 9. Then, the shoelace ends on the winding cylinder are pulled out from the left side and inserted into the push roller group 42.

[0038] During the cutting process, the motor 43 is started, which drives the pressing conveyor roller 41 to rotate. The transmission belt 45 between the pressing conveyor roller 41 and the upper push roller group 42 enables the pressing conveyor roller 41 and the upper push roller group 42 to rotate in the same direction. The gear group 44 meshing with each other on the front side of the push roller group 42 enables the lower push roller group 42 to rotate in the opposite direction to the upper push roller group 42, thereby conveying the inserted shoelace to the left.

[0039] During the rotational conveying process of the pressing conveyor roller 41 and the push roller group 42, the rotation of the pressing conveyor roller 41 can drive the rotating shaft 61 to rotate through the action of the belt 68 between the fixed pulley 46 and the moving pulley 67, which in turn drives the turntable 62 to rotate. During the rotation of the turntable 62, through the cooperation between the eccentric shaft 63 and the slide plate 64 between the turntable 62, and the upper and lower limit sliding connection of the limiting plate 66 to the cutter 65, the slide plate 64 and the cutter 65 can be driven to move up and down.

[0040] As the cutter 65 moves downward, the shoelaces in the conveying process can be cut by the cooperation between the cutter 65 and the cutting groove 7. The cutting rod 8 below the cutting groove 7 inside the horizontal plate 1 can heat melt the cut shoelace ends to prevent them from splitting.

[0041] By driving the pressing conveyor roller 41 to rotate, the push roller group 42 is rotated synchronously to realize the conveying of shoelaces. The rotation of the pressing conveyor roller 41 drives the turntable 62 to rotate, thereby realizing the up and down movement of the cutter 65 for cutting. This achieves a high degree of coordination between the shoelace conveying and cutting frequency, and improves the uniformity of cutting.

[0042] When the cutting length needs to be adjusted, the tilting pressure bar 6101 is rotated to cause the roller 6102 to press down on the top of the belt 68. After a certain degree of pressing is completed, the tilting pressure bar 6101 is limited by the fastening hinge seat 6103. During the downward pressing of the belt 68, the belt 68 on the outside of the moving pulley 67 can be contracted inward, and the moving pulley 67 can be compressed by the spring 69 and moved to both sides, so that the transmission radius of the moving pulley 67 is reduced. After the tilting pressure bar 6101 is released, the moving pulley 67 will move towards the opposite side under the action of the spring 69, so that the transmission radius of the moving pulley 67 is increased, thereby changing the transmission ratio between the fixed pulley 46 and the moving pulley 67, so that the cutting length can be adjusted more precisely.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
