Description

Technical Field

[0001] The invention relates to the technical field of shoe production equipment, in particular to a punching device for shoe making. Background Art

[0002] A shoe punching device is a tool or machine specifically designed to create holes in shoe materials. These holes can be used for a variety of purposes, such as threading, decoration, ventilation or fixing shoelaces. The design of such equipment can range from simple hand tools to complex automated machines, depending on the scale of production and demand.

[0003] Generally speaking, the shoelace holes should be symmetrically distributed on both sides of the shoe. Usually, holes are punched on one side of the shoe first, and then on the other side. This method requires the shoe to be aligned with the punching equipment twice. In traditional manual operation, workers need to place the shoe upper directly under the punching machine, which exposes them to the bottom of the punching machine.

[0017] Beneficial effects:

[0018] 1. This device is equipped with a rotating mechanism, and uses a rotating disk to sequentially convey the upper fabric to the bottom of the punching mechanism for punching, which greatly reduces the chance of direct contact between workers and punching parts and protects workers from injury.

When the upper fabric is placed on the support plate, the upper fabric can be adsorbed on the support plate under the action of the external atmospheric pressure, thereby preventing the upper fabric from shifting. At the same time, waste materials and debris can be quickly sucked into the collecting chamber after punching, which can effectively control the diffusion of waste materials and debris.

[0022] 5. The device is provided with a movable plate that can be opened and closed. When the movable plate is opened, the collected waste can be discharged from the collecting chamber, which can prevent excessive waste from being stored in the collecting chamber, causing the waste to be entangled together to form larger clumps and cause blockage of the collecting chamber. At the same time, when the movable plate is closed, the sealing property of the collecting chamber can be improved, so that the upper fabric can be stably adsorbed on the support plate, and the waste generated by punching can also be quickly sucked into the collecting chamber.

There are four supporting plates 302 fixedly connected to the top of the rotating disk 301, and the four supporting plates 302 are fixedly connected to the top of the rotating disk 301 at equal angles, and a limiting plate is fixedly connected to the top of the supporting plate 302, so that the U-shaped groove of the upper fabric is clamped on the side of the limiting plate to achieve pre-positioning of the upper fabric.

[0038] A first bevel gear 308 is fixedly connected to the top of the first transmission shaft 306, and the bracket 20 is horizontally rotatably connected to the second transmission shaft 307. A second bevel gear 309 is fixedly connected to the outside of the second transmission shaft 307. The second bevel gear 309 meshes with the first bevel gear 308. A plurality of baffles 310 are fixedly connected to the outside of the second transmission shaft 307. The plurality of baffles 310 are arranged in a ring at equal angles on the outside of the second transmission shaft 307, and the number of baffles 310 is consistent with the number of support plates 302.

[0039] During the specific operation, the shoe upper fabric that needs to be punched is placed on the support plate 302 in sequence, so that the U-shaped groove of the shoe upper fabric fits on the limit plate on the top of the support plate 302, and then the second transmission shaft 307 is rotated under the drive of the punching mechanism 50, and the second transmission shaft 307 drives the first transmission shaft 306 to rotate through the mutually meshing first bevel gear 308 and second bevel gear 309, and the rotating first transmission shaft 306 drives the second pulley 305 to rotate, and the limiting mechanism 40 is unlocked during the rotation of the first transmission shaft 306, and the second pulley 305 drives the first pulley 304 to rotate through the synchronous belt 311, and the first pulley 304 drives the rotating disk 301 to rotate through the rotating shaft 303, so that the shoe upper fabric on the support plate 302 is sequentially transported to the bottom of the punching mechanism 50 for punching, and the rotating disk 301 is used to sequentially transport the shoe upper fabric to the bottom of the punching mechanism 50 for punching, which greatly reduces the chance of direct contact between workers and punching components and protects workers from injury.

[0040] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting mechanism 40 includes a slot 401 opened on the side of the rotating disk 301, a rotating plate 403 is rotatably connected to the top of the base 10, and a block 402 is fixedly connected to one end of the rotating plate 403. The block 402 and the slot 401 match each other. A plurality of slots 401 are provided, and the number of the slots 401 is consistent with the number of the support plate 302.

[0041] The limiting mechanism 40 further includes a paddle 405 fixedly connected to the outside of the first transmission shaft 306, the paddle 405 is arranged at equal angles along the outside of the first transmission shaft 306, a spring 404 is fixedly connected to one end of the rotating plate 403 away from the block 402, and one end of the spring 404 away from the rotating plate 403 is fixedly connected to the top protrusion of the base 10. A plurality of paddles 405 are provided, and the number of paddles 405 is the same as the number of the supporting plates 302.

[0042] During specific operation, when the punching mechanism 50 is pressed down to punch holes, the block 402 is pushed by the elastic force of the spring 404 to be stuck in the slot 401. At this time, the rotating disk 301 is fixed, so that the upper fabric is fixed on the rotating disk 301, avoiding the movement of the upper fabric during punching, and ensuring the consistency of the position of each upper during punching.

[0043] When the punching mechanism 50 moves up and resets after punching, the punching mechanism 50 drives the first transmission shaft 306 to rotate, and drives the paddle 405 to rotate synchronously. The rotating paddle 405 squeezes the end of the rotating plate 403 away from the block 402, so that the rotating plate 403 drives the block 402 to disengage from the slot 401. After that, the rotating mechanism 30 can drive the rotating disk 301 to rotate ninety degrees to transport the new upper fabric to the bottom of the punching mechanism 50.

[0044] See also Figure 1 , Figure 2 , Figure 5 and Figure 7 The punching mechanism 50 is fixedly connected to the hydraulic cylinder 501 at the top of the bracket 20. The output end of the hydraulic cylinder 501 penetrates the bracket 20, and the output end of the hydraulic cylinder 501 is fixedly connected to a mounting seat 502. The bottom of the mounting seat 502 is fixedly connected to a punch 503 for punching. A punching hole 504 is provided on the support plate 302, and the punching hole 504 matches the punching head 503. The punching hole 504 penetrates the support plate 302 and the rotating disk 301 downward, and the punching hole 504 is connected to the collecting chamber 601. The punching holes 504 are arranged in two rows, and the two rows of punching holes 504 are located on both sides of the limit plate at the top of the support plate 302. At the same time, the number and position of the punching holes 504 on the support plate 302 are set to be adjustable, and can be replaced or adjusted according to specific punching requirements. Similarly, the punching head 503 is also set to be adjustable.

[0045] A push rod 505 is horizontally arranged on the side of the mounting seat 502 . One end of the push rod 505 is rotatably connected to the side of the mounting seat 502 via a rotating shaft. A limit block 506 is fixedly connected to the side of the mounting seat 502 . The limit block 506 is located below the push rod 505 .

[0046] During specific operation, when the hydraulic cylinder 501 drives the mounting seat 502 to move downward, the push rod 505 on the side of the mounting seat 502 is blocked by the baffle 310. At this time, the push rod 505 rotates along the side of the mounting seat 502, and the push rod 505 will not move the baffle 310. The mounting seat 502 continues to be pressed down to squeeze the upper fabric directly below the mounting seat 502, and the punch 503 is inserted into the punching hole 504, thereby punching the upper fabric. The waste after punching enters the punching hole 504, so that no waste is accumulated on the surface of the rotating disk 301.

[0047] After drilling, when the hydraulic cylinder 501 drives the mounting seat 502 to move up and reset, the push rod 505 on the side of the mounting seat 502 is blocked by the limit block 506, so that the push rod 505 drives the baffle 310 to rotate, and the rotating baffle 310 drives the second transmission shaft 307 to rotate, and drives the rotating disk 301 to rotate through the rotating mechanism 30. The hydraulic cylinder 501 can drive the rotating disk 301 to rotate ninety degrees every time it moves up and down.

[0048] See also Figure 6 , Figure 7 and Figure 8 The collecting mechanism 60 includes a collecting chamber 601 opened on the upper surface of the base 10, the bottom of the rotating disk 301 extends into the collecting chamber 601, and the collecting chamber 601 is provided with exhaust holes 604 and slag discharge ports 605 in sequence. The slag discharge port 605 is provided with an opening and closing mechanism 70 for controlling the discharge of waste slag from the collecting chamber 601.

[0049] A vacuum pump 603 is fixedly connected to the bottom of the base 10. The air inlet end of the vacuum pump 603 is connected to the exhaust hole 604 through a hose. The exhaust hole 604 is located directly below the punch 503. The angle between the slag discharge port 605 and the exhaust hole 604 is 180 degrees.

[0050] The bottom of the rotating disk 301 is fixedly connected with a partition 602 , which is arranged at equal angles at the bottom of the rotating disk 301 , and the bottom of the partition 602 is in conflict with the bottom of the collecting chamber 601 . A plurality of partitions 602 are provided, and the number of the partitions 602 is the same as the number of the supporting plates 302 .

[0051] During specific operation, when the upper fabric is placed on the support plate 302, since the exhaust hole 604 is located directly below the punch 503, and the bottom of the rotating disk 301 is divided into multiple independent spaces by multiple partitions 602, when punching, the space directly below the punch 503 is always evacuated to the outside by the vacuum pump 603. The vacuum pump 603 is used to evacuate air to the outside, so that a negative pressure is generated in the space directly below the punch 503 at the bottom of the rotating disk 301. When the upper fabric is placed on the support plate 302, the upper fabric can be adsorbed on the support plate 302 under the action of the external atmospheric pressure, thereby preventing the upper fabric from shifting its position.

[0052] After drilling, waste and debris can be quickly sucked into the collection chamber 601, and the waste in the collection chamber 601 is pushed by the partition 602 to the slag discharge port 605 for centralized discharge, which can effectively control the diffusion of waste and debris.

[0053] See also Figure 1 , Figure 2 , Figure 6 , Figure 7 and Fig. 9 The opening and closing mechanism 70 includes a movable plate 701 attached to the bottom of the slag discharge port 605, one side of the movable plate 701 is rotatably connected to a connecting shaft 702, both ends of the connecting shaft 702 are fixedly connected to the bottom protrusion of the base 10, a torsion spring 703 is sleeved on the outside of the connecting shaft 702, one end of the torsion spring 703 is fixedly connected to the connecting shaft 702, and the other end of the torsion spring 703 is fixedly connected to the movable plate 701, and a protrusion 704 is fixedly connected to the top of the movable plate 701, and the top of the protrusion 704 passes through the slag discharge port 605 and extends into the collecting chamber 601.

[0054] In specific operation, during the rotation of the rotating disk 301, the partition 602 at the bottom of the rotating disk 301 successively contacts the top of the protrusion 704, and the protrusion 704 pushes the movable plate 701 downward to rotate. At this time, the slag discharge port 605 is in an open state. The rotating movable plate 701 accumulates force on the torsion spring 703. When the partition 602 is out of contact with the protrusion 704, the elastic force of the torsion spring 703 causes the movable plate 701 to close the slag discharge port 605. When the slag discharge port 605 is opened, the partition 602 2 Pushing the waste to be discharged from the slag discharge port 605 can prevent the collection chamber 601 from storing too much waste, causing the waste to be entangled together to form a large mass and cause the collection chamber 601 to be blocked. At the same time, the centralized collection of waste can avoid the pollution problem caused by the random scattering of waste. When the slag discharge port 605 is closed, the sealing property of the collection chamber 601 can be improved, so that the upper fabric can be stably adsorbed on the support plate 302, and the waste generated by punching can also be quickly sucked into the collection chamber 601.

[0055] Working principle:

[0056] The shoe upper fabrics that need to be punched are placed on the support plate 302 in turn, and the vacuum pump 603 in the collecting mechanism 60 first generates negative pressure to adsorb the shoe upper fabrics on the support plate 302. Then the punching mechanism 50 presses down to punch holes, and the waste generated by the punching is absorbed into the collecting chamber 601 by the collecting mechanism 60. Then the punching mechanism 50 moves up and resets. At this time, the punching mechanism 50 first drives the limiting mechanism 40 to release the fixation of the rotating disk 301, and then the punching mechanism 50 drives the rotating mechanism 30 to rotate ninety degrees, so as to transport the new shoe upper fabric to the bottom of the punching mechanism 50. During the rotation of the rotating disk 301, the opening and closing mechanism 70 is driven to open intermittently to discharge the waste in the collecting chamber 601.
