Description

Technical Field

[0001] This utility model relates to the technical field of shoe sole rough edge cutting device, specifically a cutting device for shoe sole processing based on thermoplastic polyurethane infiltration composite. Background Technology

[0002] Thermoplastic polyurethane (TPU) infiltrated composite soles are high-performance soles that combine the high abrasion resistance and high elasticity of TPU with the lightweight cushioning properties of other materials (such as EVA and rubber).

[0003] Currently, the production process of thermoplastic polyurethane infiltrated composite shoe soles requires the cutting of rough edges on the soles. However, commonly used cutting equipment is inconvenient for loading and unloading soles. For example, CN220529427U discloses a cutting device for shoe sole processing, which includes a base. The base has multiple fixed plates inside, and multiple first rotating columns are arranged inside the fixed plates. Each first rotating column has a worm gear fixedly connected to its side wall. A worm is meshed with the opposite side of the worm gear. A first connecting plate is rotatably connected to one side of the side wall of the first rotating column, and the first connecting plate is fixedly connected to the worm gear.

[0004] As can be seen from the above-disclosed scheme, the cutting equipment needs to be clamped and fixed by a clamping plate. The clamping plate takes a long time to clamp and fix the sole, which reduces the convenience of feeding the sole. Then, the pressing plate presses the cutting blade downward, and the sole between the cutting blade and the pressing plate is cut. However, the cut sole is inside the cutting blade and needs to be removed, which makes it inconvenient to unload the sole. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cutting device for shoe sole processing based on thermoplastic polyurethane infiltration composite, thereby solving the problem that existing cutting devices are inconvenient for loading and unloading shoe soles.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for shoe sole processing based on thermoplastic polyurethane infiltration composite, comprising a cutting worktable, a support plate fixedly connected to the surface of the cutting worktable, a hydraulic arm fixedly installed on the top of the support plate, a cutting mechanism fixedly connected to one end of the hydraulic arm, a through hole on the surface of the cutting worktable, a positioning sleeve fixedly connected to the outer side of the through hole, a shoe sole positioning fixture movably connected to the inner wall of the positioning sleeve, a guide rail fixedly connected to the bottom of the cutting worktable, and a storage mechanism slidably connected to the surface of the guide rail. Through the provided shoe sole positioning groove, through hole, spring telescopic rod, and extrusion column, the cut shoe sole can be extruded downwards when the cutting blade punches down the rough edges of the shoe sole, allowing the cut shoe sole to exit downwards without needing to be removed, thus improving the convenience of shoe sole loading. Furthermore, through the provided storage mechanism, the cut shoe soles that fall downwards through the through hole can be stored and stacked, allowing workers to remove the stacked shoe soles from the storage groove at once, further improving the convenience of shoe sole unloading.

[0007] Preferably, the cutting mechanism includes a fixed plate, the top of which is fixedly connected to one end of the hydraulic arm, and a plurality of spring telescopic rods are fixedly connected to the bottom of the fixed plate. The other end of each spring telescopic rod is fixedly connected to a connecting plate, and the bottom of the connecting plate is fixedly connected to a cutting blade. The spring telescopic rods can support the position of the cutting blade and also have a buffering effect, thus extending the service life of the cutting blade.

[0008] Preferably, the storage mechanism includes a base plate, and four limiting plates are fixedly connected to the surface of the base plate. The four limiting plates and the base plate together form a storage groove. The center of the storage groove and the center of the through hole are on the same straight line. The storage groove can automatically and neatly store the dropped shoe soles.

[0009] Preferably, a pressing column is fixedly connected to the bottom center of the fixing plate, and a center hole is opened at the center of the connecting plate. One end of the pressing column is located in the center hole. When the spring telescopic rod retracts, the pressing column can press down on the cut shoe sole.

[0010] Preferably, the surface of the shoe sole positioning fixture has a shoe sole positioning groove, the shape of which is the same as the outer contour of the shoe sole, and the shoe sole positioning groove is coaxial with the through hole. The shoe sole positioning groove facilitates quick positioning of the shoe sole to be cut.

[0011] Preferably, an clearance groove is formed between adjacent limiting plates, and a slider and a handle are fixedly connected to the outer side of the limiting plates. The slider is connected to the guide rail, so that the storage mechanism can slide out from the bottom of the cutting workbench, and the handle facilitates the pushing and pulling of the storage mechanism.

[0012] Preferably, the surface of the base plate has strip-shaped holes, which facilitate the downward cleaning of dust from the surface of the base plate.

[0013] Compared with the prior art, this utility model provides a cutting device for shoe sole processing based on thermoplastic polyurethane infiltration composite, which has the following beneficial effects:

[0014] By incorporating a positioning groove, through-hole, spring telescopic rod, and extrusion column on the sole, the cut sole can be extruded downwards when the cutting blade punches down the rough edges of the sole. This allows the cut sole to exit downwards without needing to be removed, improving the convenience of loading the sole. Furthermore, the storage mechanism allows for the collection and stacking of the cut soles that have fallen downwards through the through-hole. Workers can then remove the stacked soles from the storage slot at once, further enhancing the convenience of unloading the sole. Attached Figure Description

[0021] 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.

[0022] This utility model provides a technical solution for a cutting device for processing shoe soles based on thermoplastic polyurethane infiltrated composites. The device includes a cutting worktable 1, a support plate 14 fixedly connected to the surface of the cutting worktable 1, a hydraulic arm 15 fixedly mounted on the top of the support plate 14, a hydraulic cylinder at one end of the hydraulic arm 15 connected to a start switch, and a cutting mechanism 2 fixedly connected to the other end of the hydraulic arm 15. A through hole 11 is formed on the surface of the cutting worktable 1, a positioning sleeve 12 is fixedly connected to the outer side of the through hole 11, and a shoe sole positioning fixture 3 is movably connected to the inner wall of the positioning sleeve 12. A shoe sole positioning groove 31 is formed on the surface of the shoe sole positioning fixture 3, the shape of which is the same as the outer contour of the shoe sole, and the shoe sole positioning groove 31 is coaxial with the through hole 11. The sole positioning groove 31 facilitates quick positioning of the sole to be cut. The depth of the sole positioning groove 31 is the same as the thickness of the sole parting surface. The rough edges of the sole are all located at the parting surface. After the sole is placed in the sole positioning groove 31, the bottom of the rough edges contacts the surface of the sole positioning fixture 3, which facilitates easy downward cutting by the cutting blade 26. The bottom of the sole positioning groove 31 is provided with a hole with an inner diameter slightly smaller than that of the sole positioning groove 31. This not only facilitates the sole positioning groove 31 to limit the sole, but also allows the sole to fall into the through hole 11 through the hole when it is pressed downward. The bottom of the cutting worktable 1 is fixedly connected to the guide rail 13. The guide rail 13 is a telescopic track, which facilitates the storage mechanism 4 to slide out of the bottom of the cutting worktable 1. The surface of the guide rail 13 is slidably connected to the storage mechanism 4.

[0023] The cutting mechanism 2 includes a fixed plate 21. The top of the fixed plate 21 is fixedly connected to one end of the hydraulic arm 15. Several spring telescopic rods 22 are fixedly connected to the bottom of the fixed plate 21. The other end of the spring telescopic rods 22 is fixedly connected to a connecting plate 24. A cutting blade 26 is fixedly connected to the bottom of the connecting plate 24. The spring telescopic rods 22 can support the position of the cutting blade 26 and also have a buffering effect, extending the service life of the cutting blade 26. A pressing column 23 is fixedly connected to the center of the bottom of the fixed plate 21. A center hole 25 is opened at the center of the connecting plate 24. One end of the pressing column 23 is inside the center hole 25. When the spring telescopic rods 22 retract, the pressing column 23 can press the cut shoe sole downward.

[0024] The storage mechanism 4 includes a base plate 41. Four limiting plates 43 are fixedly connected to the surface of the base plate 41. The four limiting plates 43 and the base plate 41 enclose a storage groove 47. The center of the storage groove 47 is on the same straight line as the center of the through hole 11. The storage groove 47 can automatically and neatly store the dropped shoe soles. An clearance groove 44 is enclosed between adjacent limiting plates 43. The clearance groove 44 makes it easy for fingers to enter and exit the storage groove 47 to lift the stacked shoe soles. A slider 45 and a handle 46 are fixedly connected to the outside of the limiting plates 43. The slider 45 is connected to the guide rail 13, so that the storage mechanism 4 can slide out of the bottom of the cutting workbench 1. The handle 46 facilitates the pushing and pulling of the storage mechanism 4. A strip hole 42 is opened on the surface of the base plate 41. The strip hole 42 facilitates the downward cleaning of dust on the surface of the base plate 41.

[0025] The working principle of this device is as follows: During operation, the operator places the shoe sole to be cut into the shoe sole positioning groove 31, and then activates the hydraulic cylinder, causing the hydraulic arm 15 to extend downwards. The downward extension of the hydraulic arm 15 drives the fixed plate 21 and the connecting plate 24 to move downwards. The downward movement of the connecting plate 24 drives the cutting blade 26 to move downwards to cut the rough edges of the shoe sole. After the cutting blade 26 has completed its downward cutting, the fixed plate 21 continues to move downwards to compress the spring telescopic rod 22. The spring telescopic rod 22, under compression, begins to contract. The contraction of the spring telescopic rod 22 causes the extrusion column 23 to continue to move downwards. The extrusion column 23 moves downwards to compress the cut shoe sole, squeezing the sole. The pressure column 23 presses downwards into the bottom hole of the sole positioning groove 31, leaving the sole positioning groove 31 exposed. At this time, the hydraulic arm 15 drives the cutting blade 26 to retract upwards to complete the punching. Then, the sole to be cut is installed. Next, the sole rough edges are cut in the same way as above, so that the sole is pressed downwards into the sole in the bottom hole of the sole positioning groove 31. At this time, the sole falls through the through hole 11 and enters the storage groove 47 for storage. Then, the sole rough edges are cut in the same way as above. After the sole in the storage groove 47 is full, the storage mechanism 4 is pulled out of the cutting worktable 1. Then, the neatly stacked soles are moved out of the storage groove 47 and placed in the transfer vehicle.
