[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A shoe sole cutting protection device includes a workbench 1, a movable groove 2 is provided on the inner side of the top of the workbench 1, a protective mechanism 3 is rotatably connected to the inner side of the movable groove 2, and a cutting mechanism 4 is threadedly connected to the top of the protective mechanism 3.

[0027] The protective mechanism 3 includes a lead screw 31, a first motor 32, a fixed block 33, a stepper motor 34, a rotating rod 35, a protective pressure plate 36, a limiting block 37, and a baffle 38. The lead screw 31 is rotatably connected to the inner side of the moving groove 2. The first motor 32 is installed on the right side of the workbench 1. The fixed block 33 is welded to both sides of the top of the workbench 1. The stepper motor 34 is installed on the left side of the left fixed block 33. The rotating rod 35 is rotatably connected to the inner side of the fixed block 33. The output end of the stepper motor 34 on the right side passes through the fixed block 33 and is fixedly connected to the left side of the rotating rod 35. The protective pressure plate 36 is welded to the surface of the rotating rod 35. The limiting block 37 is welded to both sides of the right side of the protective pressure plate 36. The baffle 38 is fixedly connected to the surface of the limiting block 37.

[0028] In this embodiment: a workbench 1 provides a stable mounting platform for the protective mechanism 3, the cutting mechanism 4, and the moving groove 2. A PLC controller is installed on the right side of the top of the workbench 1. The moving groove 2 limits the rotation position of the lead screw 31 and cooperates with the threaded sleeve block 42, allowing the lower template 41 to slide horizontally along the top of the workbench 1 when the first motor 32, controlled by the PLC, drives the lead screw 31 to rotate. The lead screw 31 is threadedly connected to the threaded sleeve block 42. When the first motor 32 rotates under the control of the PLC controller, it drives the lower template 41 to move along the workbench 1. Under the control of the PLC controller, the first motor 32 provides power to the lead screw 31, realizing the movement of the lower template 41. The fixing block 33 provides a stable rotation support point for the rotating rod 35, ensuring the protection... The stability of the pressure plate 36 during rotation is ensured by the stepper motor 34, which, under the control of the PLC, controls the rotation angle and speed of the rotating rod 35, causing the protective pressure plate 36 to flip to the top of the lower template 41. This quickly forms a protective barrier before the cutting operation, preventing operators from accidentally contacting the cutting parts and ensuring personnel safety. The rotating rod 35 transmits the power of the stepper motor 34 to the protective pressure plate 36, enabling the protective pressure plate 36 to rotate. The protective pressure plate 36 flips under the drive of the rotating rod 35, working with the limit block 37 and the baffle 38 to protect the cutting area. At the same time, it can also provide auxiliary fixation for the shoe soles placed on the lower template 41, preventing the shoe soles from shifting during cutting. The limit block 37 fixes the position of the baffle 38, which can protect the right side of the protective pressure plate 36.

[0029] Specifically, such as Figure 4 , Figure 5 As shown, the cutting mechanism 4 includes a lower template 41, a threaded sleeve block 42, a mounting plate 43, a threaded rod 44, a limiting rod 45, a threaded sleeve 46, a sliding sleeve 47, a cutting blade 48, and a second motor 49. The lower template 41 is slidably connected to the top of the worktable 1.

[0030] Specifically, such as Figure 4 , Figure 5As shown, the threaded sleeve block 42 is welded to the right side of the bottom of the lower template 41, the threaded sleeve block 42 is threaded to the surface of the threaded rod 31, the mounting plate 43 is welded to both sides of the top of the workbench 1, the threaded rod 44 is rotatably connected to the inner side of the rear mounting plate 43, the left side of the threaded rod 44 is connected to the connecting shaft by a flat key, and the limiting rod 45 is welded to the inner side of the front mounting plate 43.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, the threaded sleeve 46 is threadedly connected to the surface of the threaded rod 44, the sliding sleeve 47 is slidably connected to the surface of the limiting rod 45, the cutting blade 48 is welded to the top of the threaded sleeve 46 and the sliding sleeve 47, the cutting blade 48 is slidably connected to the top of the lower template 41, the second motor 49 is installed on the left side of the rear mounting plate 43, and the output end of the second motor 49 on the right side passes through the mounting plate 43 and is fixedly connected to the left side of the connecting shaft.

[0032] In this embodiment: By setting the lower template 41 to provide a stable support surface for shoe sole cutting, and by connecting with the thread sleeve block 42, the cut shoe sole can be transported to the right side of the top of the worktable 1 under the drive of the lead screw 31. The thread sleeve block 42 converts the rotation of the lead screw 31 into the linear motion of the lower template 41. The mounting plate 43 provides the mounting base for the threaded rod 44 and the limit rod 45. The threaded rod 44 rotates under the drive of the second motor 49 controlled by the PLC controller. Through the threaded engagement with the threaded sleeve 46, it drives the cutting blade. 48 moves along the cutting direction of the shoe sole. The limiting rod 45 limits the sliding sleeve 47 to prevent it from shifting or rotating during the movement. The threaded sleeve 46 cooperates with the threaded rod 44 to convert the rotation of the threaded rod 44 into its own linear motion, which drives the cutting blade 48 to move. The sliding sleeve 47 slides on the limiting rod 45 to provide stable support and guidance for the connecting rod, ensuring the stability of the cutting blade 48 during the movement. The cutting blade 48 can cut the shoe sole. The second motor 49 can drive the threaded rod 44 to rotate through the connecting shaft.

[0033] Specifically, such as Figure 1 As shown, reinforcing rings 5 ​​are welded to both sides of the cutting blade 48, and the surface of the reinforcing rings 5 ​​is coated with anti-corrosion paint.

[0034] Specifically, such as Figure 3 As shown, a protective pad 6 is fitted on the surface of the baffle 38, and the protective pad 6 is made of nitrile rubber material.

[0035] In this embodiment: by setting the reinforcing ring 5, the connection strength between the cutting blade 48 and the threaded sleeve 46 and the sliding sleeve 47 can be enhanced. By setting the anti-corrosion coating, corrosive substances such as humid air and processing debris can be isolated, preventing the cutting blade 48 from being corroded and extending its service life. By setting the protective pad 6, the impact force can be absorbed when the cutting blade 48 accidentally touches the baffle 38. By setting the protective pad 6 to be made of nitrile rubber, the excellent wear resistance and tear resistance of nitrile rubber can effectively resist the friction between the shoe sole and the baffle 38 and the impact of debris during the cutting process, preventing damage to the surface of the baffle 38.

[0036] Specifically, such as Figure 2 As shown, the right side of the rotating rod 35 extends through and to the outside of the right-side fixed block 33, and a limit ring 7 is fixedly connected to the right side of the rotating rod 35.

[0037] Specifically, such as Figure 1 As shown, a support column 8 is welded to the chamfer at the bottom of the workbench 1, and the bottom of the support column 8 is engraved with anti-slip texture.

[0038] In this embodiment: by setting the limiting ring 7, the axial displacement of the rotating rod 35 can be limited, preventing it from moving around when driven by the stepper motor 34. By setting the support column 8, the contact area between the equipment and the ground is increased, effectively improving the overall stability of the equipment. By setting the anti-slip texture, the friction with the ground is increased.

[0039] Working principle: First, the operator places the shoe sole on the lower template 41. Then, the operator controls the first motor 32 to operate via the PLC controller. The first motor 32 drives the lead screw 31 to rotate within the moving groove 2. The lead screw 31 is threadedly connected to the threaded sleeve block 42 at the bottom of the lower template 41, thereby causing the lower template 41 to slide horizontally along the top of the worktable 1, conveying the shoe sole to the cutting position. Next, the operator controls the stepper motor 34 to start via the PLC controller. The output end of the stepper motor 34 drives the rotating rod 35 to rotate within the fixed block 33. The rotating rod 35 causes the protective pressure plate 36 to flip, so that the protective pressure plate 36, together with the limit block 37 and the baffle 38, forms a protective barrier for the cutting area. The barrier, along with the protective pressure plate 36, helps to fix the sole and prevent displacement during cutting. Then, the operator controls the second motor 49 through the PLC controller. The second motor 49 drives the threaded rod 44 to rotate through the connecting shaft. The threaded rod 44 is threadedly engaged with the threaded sleeve 46. At the same time, the limit rod 45 limits the sliding sleeve 47, so that the threaded sleeve 46 and the sliding sleeve 47 drive the cutting blade 48 to move smoothly along the cutting direction of the sole, completing the cutting operation of the sole. Finally, after the cutting operation is completed, the operator controls the first motor 32 to rotate again through the PLC controller, driving the lower template 41 to transport the cut sole to the top right side of the workbench 1 so that the operator can take it out.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
