Description

Technical Field

[0001] The utility model relates to a shoe last processing device, in particular to a shoe last processing fixing and pressing device, belonging to the technical field of shoe last processing. Background Art

[0002] Shoe lasts occupy an important position in the shoemaking industry. Shoe lasts are the mother of shoes and the molding mold of shoes. Shoe lasts not only determine the shape and style of shoes, but also determine whether the shoes fit well and whether they can protect the feet. In the production and processing, different styles of shoes can be produced according to the production of different types of shoe lasts.

[0003] The processing of shoe lasts often involves drilling holes on the top surface of the shoe last. The purpose is to put the shoe last on the shoe last for shaping after the shoe is manufactured. When the shoe last needs to be removed from the shoe, a professional tool is inserted into the drill hole to pull the shoe last and remove the shoe last from the shoe. However, when drilling a hole on the top of the shoe last, the existing device first starts the drilling device, then places the shoe last directly on the base below the drill bit, and then supports the shoe last with one hand and then uses the other hand to pull down. Pull the drilling device to make the drill drill a hole on the top of the shoe last. Since the shoe last is only held by hand and there is no fixing device, the worker needs to press the shoe last vigorously when drilling with the drill to prevent the shoe last from moving, which will cause drilling failure. However, pressing the shoe last for a long time will cause the worker's arm to be tired, making the force of pressing the shoe last smaller, causing the shoe last to move during drilling. At the same time, the movement of the shoe last under the action of the drilling device may also cause injury to the worker. Utility Model Content

[0004] The purpose of the present utility model is to provide a shoe last processing, fixing and pressing device in order to solve the above-mentioned problem. The shoe last is placed between two clamping blocks and then pressed downward so that the shoe last contacts the support plate. At the same time, the clamping blocks are rotated to contact the shoe last, so that the shoe last can be fixed by the clamping blocks. There is no need to press and support with hands, thereby reducing dangerous operations caused by arm fatigue caused by workers pressing the shoe last and reducing the risk of injury to workers.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a shoe last processing, fixing and pressing device, including a base, on which a shoe last is detachably mounted, a fixed structure installed on the top of the base, the fixed structure including a support plate, a support plate slidably connected inside the base, and two sliding rods slidably connected to the side ends of the support plate in a parallel and symmetrical relationship, a fixed shaft fixedly connected to the top of the sliding rod, a rotating column rotatably connected to the sliding rod through the fixed shaft, a torsion spring fixedly connected between the rotating column and the fixed shaft, and a clamping block fixedly connected to the rotating column.

[0006] Preferably, a rubber block is fixedly connected to the top of the clamping block, and the rubber block contacts the shoe last.

[0007] Preferably, the cross section of the clamping block is in a “V” shape, and the cross section of the rubber block is in a “V” shape.

[0008] Preferably, a first baffle is fixedly connected to a side end of the slide rod, the first baffle is slidably connected to the support plate, and a first spring is fixedly connected between the first baffle and the support plate.

[0010] Preferably, a slot is provided on the left side of the guide rod, and an insertion rod is slidably connected in the base, and the insertion rod is plugged into the slot.

[0011] Preferably, the cross-section of the top end of the insertion rod is in the shape of a right triangle, and the cross-section of the slot is in the shape of a right triangle.

[0012] Preferably, a second baffle is fixedly connected to the bottom end of the guide rod, the second baffle is slidably connected to the base, and a second spring is fixedly connected between the second baffle and the base.

[0013] Preferably, a third baffle is fixedly connected to the side end of the insertion rod, the third baffle is slidably connected to the base, and a third spring is fixedly connected between the third baffle and the base.

[0014] Preferably, a resistance block is fixedly connected to the top of the base, the cross section of the resistance block is a "V"-shaped structure, and the resistance block is in contact with the shoe last.

[0015] The beneficial effect of the present invention is as follows: first, the shoe last is placed directly above the two clamping blocks, and then the slide bar is slid to adjust the distance between the two slide bars to a suitable position, and then the shoe last is pressed downwards. When the shoe last conflicts with the clamping block, the shoe last continues to be pressed, and the shoe last will cause the clamping block to rotate.

[0021] See also Figure 1-3 As shown, a shoe last processing, fixing and pressing device includes a base 1, on which a shoe last 2 is detachably mounted, a fixing structure 3 is mounted on the top of the base 1, and the fixing structure 3 includes a support plate 301, and the support plate 301 is slidably connected in the base 1, and the side ends of the support plate 301 are slidably connected to two sliding rods 302 distributed in a parallel and symmetrical relationship, and the top of the sliding rod 302 is fixedly connected to a fixed shaft 303, and the sliding rod 302 is rotatably connected to a rotating column 305 through the fixed shaft 303, and a torsion spring 304 is fixedly connected between the rotating column 305 and the fixed shaft 303, and a clamping block 306 is fixedly connected to the rotating column 305.

[0022] As a technical optimization solution of the present invention, a rubber block 307 is fixedly connected to the top of the clamping block 306, and the rubber block 307 contacts the shoe last 2. The contact between the rubber block 307 and the shoe last 2 prevents the surface of the shoe last 2 from being scratched.

[0023] As a technical optimization solution of the present invention, the cross-section of the clamping block 306 is a "V"-shaped structure, and the cross-section of the rubber block 307 is a "V"-shaped structure. Since the cross-sections of the clamping block 306 and the rubber block 307 are both "V"-shaped structures, multiple points of contact can be achieved when clamping the shoe last 2.

[0024] As a technical optimization solution of the present invention, the side end of the sliding rod 302 is fixedly connected to a first baffle 308, the first baffle 308 is slidingly connected to the support plate 301, and a first spring 309 is fixedly connected between the first baffle 308 and the support plate 301. The distance between the two sliding rods 302 can be adjusted by the first spring 309, and shoe lasts 2 of different sizes can be clamped.

[0025] As a technical optimization solution of the present invention, a limiting structure 4 is installed in the base 1, and the limiting structure 4 includes a guide rod 401. The guide rod 401 is slidably connected in the base 1, and the guide rod 401 is fixedly connected to the bottom end of the support plate 301. The guide rod 401 can be used to guide the support plate 301 to slide in the base 1.

[0026] As a technical optimization solution of the present invention, a slot 402 is provided on the left side of the guide rod 401, and an insertion rod 403 is slidably connected to the base 1. The insertion rod 403 is plugged into the slot 402. The guide rod 401 can be fixed and limited through the insertion rod 403 and the slot 402.

[0027] As a technical optimization solution of the present invention, the cross-section of the top end of the insertion rod 403 is in the shape of a right triangle, and the cross-section of the slot 402 is in the shape of a right triangle. The cross-section of the top end of the insertion rod 403 is in the shape of a right triangle, so that the guide rod 401 cannot slide when there is no external force pulling the insertion rod 403.

[0028] As a technical optimization solution of the present invention, the bottom end of the guide rod 401 is fixedly connected to a second baffle 404, the second baffle 404 is slidably connected to the base 1, and a second spring 405 is fixedly connected between the second baffle 404 and the base 1. The second spring 405 can drive the guide rod 401 to move upward, thereby separating the shoe last 2 from the base 1, making it convenient to disassemble the shoe last 2.

[0029] As a technical optimization solution of the present invention, the side end of the insertion rod 403 is fixedly connected to a third baffle 406, and the third baffle 406 is slidably connected to the base 1. A third spring 407 is fixedly connected between the third baffle 406 and the base 1. The third spring 407 prevents the insertion rod 403 from separating from the slot 402 under a smaller force, thereby limiting the insertion rod 403.

[0030] As a technical optimization solution of the present invention, a resistance block 408 is fixedly connected to the top of the base 1. The cross-section of the resistance block 408 is a "V"-shaped structure. The resistance block 408 resists the shoe last 2. The position of the shoe last 2 can be located by the resistance block 408 so that the drilling position of the top of the shoe last 2 is the same.

[0031] When the present invention is in use, the shoe last 2 is first placed right above the two clamping blocks 306, and the heel of the shoe last 2 is parallel to the groove of the "V" shape of the conflicting block 408, and then the shoe last 2 is pressed downward. When the shoe last 2 conflicts with the rubber block 307 at the top of the clamping block 306, the shoe last 2 is continued to be pressed, and the shoe last 2 will cause the rubber block 307 and the clamping block 306 to drive the rotating column 305 to rotate on the fixed shaft 303. When the shoe last 2 is pressed downward, the sliding rod 302 will be squeezed according to the width of the shoe last 2, causing the sliding rod 302 to slide in the support plate 301, and the sliding rod 302 drives the first baffle 308 to slide in the support plate 301, so that the first baffle 308 generates a tensile force on the first spring 309. When the shoe last 2 is engaged between the two sliding bars 302, the sliding bar 302 will move towards the shoe last 2 under the action of the first spring 309, so that the rubber block 307 tightly clamps the shoe last 2, and then continues to press the shoe last 2 until the shoe last 2 contacts the support plate 301 and squeezes the support plate 301 into the inside of the base 1, and the support plate 301 drives the guide rod 401 to slide toward the bottom of the base 1. When the top of the support plate 301 is parallel to the top of the base 1, the heel of the shoe last 2 contacts the interference block 408, and the interference block 408 can fix the clamping position of the shoe last 2, so that the drilling position of the top of the shoe last 2 is the same, and under the elastic force of the third spring 407 in the base 1, the third baffle 406 will be driven to move towards the guide rod 401. When the shoe last 2 is fixed on the support plate 301, the third baffle 406 drives the insertion rod 403 to move, so that the insertion rod 403 is plugged into the slot 402. Since the cross-section of the top end of the insertion rod 403 is in the shape of a right triangle, when the insertion rod 403 is plugged into the slot 402, the guide rod 401 will be fixed, so that the support plate 301 can be fixed to prevent the support plate 301 from sliding up and down, so that the shoe last 2 can be fixed on the support plate 301, and the clamping block 306 and the fixed shaft 303 are connected by the torsion spring 304. Under the action of the torsion spring 304, the clamping block 306 will clamp the shoe last 2 tightly and fix it to prevent the shoe last 2 from falling off from the clamping block 306. Then, the drilling device is pulled downward to make the drill drill a hole in the top of the shoe last 2, so that there is no need to use The user presses and supports the shoe last 2 with his hand, and the distance between the two slide bars 302 can be adjusted according to the size of the shoe last 2 through the first spring 309, so that the clamping block 306 can clamp shoe lasts 2 of different widths. The clamping block 306 and the rubber block 307 can be in close contact with the shoe last 2 through the torsion spring 304, and the cross-sections of the clamping block 306 and the rubber block 307 are both "V"-shaped, which can resist the shoe last 2 at multiple points. When the shoe last 2 is drilled, it is only necessary to pull the insertion rod 403 outward to separate the insertion rod 403 from the slot 402, and then drive the second baffle 404 to move upward under the elastic force of the second spring 405, and the second baffle 404 drives the guide rod 401 to move upward, and the guide rod 401 drives the support plate 301 to move upward.This allows the shoe last 2 to be separated from the base 1 without any interference, making it easier to remove the shoe last 2 from the base 1. The clamping block 306 holds the shoe last 2, eliminating the need for workers to constantly press on the shoe last 2 while drilling holes in it. This reduces the risk of dangerous operations caused by arm fatigue from pressing on the shoe last 2 and reduces the risk of injury to workers.
