Description

Technical Field

[0001] The invention relates to the technical field of punch feeding devices, in particular to a feeding device for processing livestock ear tags. Background Art

[0002] The ear tag is one of the animal identifications, used to prove the identity of livestock and carry the individual information of livestock. It is applied to the ears of livestock and can be manufactured by stamping and forming using a punch press.

[0003] Stamping die bed is used for blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion of sheet materials through dies, and is widely used in various fields.

[0004] There are two types of existing punch press feeding. One is to control the feeding through CNC, which is expensive, and the other is to manually place the material, which is suitable for manufacturing and use in small and medium-sized factories. When placing the material manually, the operator's hands or fingers need to frequently enter the mold working area. If the equipment is accidentally started or not effectively protected, it is very easy to cause serious injuries such as squeezing, shearing, and broken fingers. Even if a foot switch is used, fatigue, misoperation or equipment failure may still cause accidental stamping. Manual placement is not only unsafe but also inefficient. Therefore, this application provides a feeding device for livestock ear tag processing to meet the needs. Summary of the Invention

When the staff places the ear tag material to be processed, there will be no direct contact with the stamping head 2, which protects the staff's operating risks. At the same time, the punching machine's own power is used to drive the feeding, which has a simple structure, low cost, and high reliability, reducing production costs and improving stability. The unloading assembly 4 is located on one side of the stamping frame 1 and is used to cooperate with the feeding assembly 3 to unload the processed ear tag. The discharge port 72 is used to discharge the stamped ear tag to avoid affecting the stamping of the next ear tag. The discharge hole 71 is used to cooperate with the unloading assembly 4 to eject the formed ear tag from the discharge port 72 through the unloading assembly 4.

[0044] like Figure 1 、 Figure 3 and Figure 13 As shown, the stamping frame 1 consists of an upper plate, a pillar and a lower plate, and the two ends of the pillar are fixedly connected to the upper plate and the lower plate respectively; the upper plate is fixedly connected to a sliding tube 11 on one side close to the feed component 3, and the two sides of the lower plate are fixedly connected to a first mounting ring 12, the lower plate is fixedly connected to a connecting rod 13 on one side close to the feed component 3, and one end of the connecting rod 13 is fixedly connected to a second mounting ring 14, and the lower plate is fixedly connected to a vertical plate 15 on one side close to the unloading component 4, and the bottom of the lower plate is fixedly connected to the corresponding positions on both sides of the material conveyor belt 5 with unloading protrusions 16, and the unloading protrusions 16 are used to unload the waste after stamping; a limiting slide groove 111 is provided on the inner surface wall of the slide tube 11, and the length of the limiting slide groove 111 is greater than the travel length of the output shaft of the punching head 2.

[0045] like Figures 2 to 6As shown, the feed assembly 3 includes a fixed tube 31 fixedly connected to the output shaft of the punch head 2, the outer wall of the fixed tube 31 is fixedly connected to a bent rod 32, the inner wall of the slide tube 11 is slidably connected to a slide cylinder 33, the bent rod 32 and the slide cylinder 33 are fixedly connected, and the bottom of the slide cylinder 33 is rotatably connected to the second connecting rod 37. When the output shaft of the punch head 2 works up and down, it will drive the fixed tube 31 fixed on its outer wall to work up and down, thereby driving the slide cylinder 33 fixedly connected to it to work up and down through the bent rod 32, and then driving the second connecting rod 37 to move up and down through the slide cylinder 33; the inner wall of the first mounting ring 12 is rotatably connected to the second rotating rod 36, and the two ends of the second rotating rod 36 pass through the first mounting ring 12 so that it rotates inside the first mounting ring 12, and the inner wall of the second mounting ring 14 is rotatably connected to the first rotating rod 35, and the first rotating rod 35 is supported and limited by the second mounting ring 14 so that it can only The second link 37 is connected to the two rotating pieces 34 by the clamping unit 38.

[0046] The outer wall of the slide cylinder 33 is fixedly connected to the position corresponding to the limit slide groove 111 with a limit slider 331 adapted thereto. The slide cylinder 33 is limited and slides inside the limit slide groove 111 through the limit slider 331. One end of the second connecting rod 37 is provided with a first connecting hole 371, and the other end is provided with a plurality of evenly distributed second connecting holes 372. The inner wall of the slide cylinder 33 is fixedly connected to the first connecting rod 332 adapted to the first connecting hole 371. The first connecting hole 371 is sleeved on the outer wall of the first connecting rod 332; the second rotating rod 36 is fixedly connected to the outer wall of the first mounting ring 12 near the outer wall of the first mounting ring 12. The first mounting ring 12 is rotatably connected to the side opposite to the ratchet 361 by a pawl, and the pawl is meshed with the ratchet 361. Through the cooperation of the pawl and the ratchet 361, the second rotating rod 36 can only move in one direction, thereby making the material conveyor belt 5 only move in one direction and will not carry the material backward, thereby improving the positioning accuracy.

[0047] like Figure 6 and Figure 7When the second locking nut 372 is in the unlocking state, the locking nut 382 is locked and the locking nut 384 is locked. The cam 384 is provided with a locking groove 3821, and the outer wall of the locking groove 3821 is provided with a snap ring 383. The outer wall of the fourth connecting rod 382 is slidably connected with a block 384. The length of the fourth connecting rod 382 is twice the thickness of the block 384. The diameter of the third connecting rod 381 is consistent with the inner diameter of the second connecting hole 372. The two rotating pieces 34 have a limiting slot 341 on the opposite sides. The limiting slot 341 is formed by connecting a plurality of herringbone-shaped slots, wherein the shape of the herringbone-shaped slot is consistent with the shape of the block 384. When the clamping unit 38 is installed on the second connecting hole 372 at different positions, the rotation radius of the second rotating rod 36 can be adjusted, thereby adjusting the periodic conveying distance of the material conveyor belt 5. When installing the clamping unit 38, the blocks 384 on both sides are clamped on the corresponding limiting slots 341, and then the snap ring 383 is clamped on the locking groove 3821 to limit the position of the block 384.

[0048] like Figure 2 and Figures 8 to 11As shown, the unloading assembly 4 includes a unloading rod 41 slidably connected to the vertical plate 15 and a traction plate 44 fixedly connected to one side of the connecting rod 13; one end of the unloading rod 41 is fixedly connected to the stopper 411, and the other end passes through the vertical plate 15 and the unloading hole 71 in sequence and extends to the interior of the stamping die 7, and the outer wall of the unloading rod 41 is sleeved with a return spring 42, and the two ends of the return spring 42 are respectively fixedly connected to the outer wall of the unloading rod 41 and one side of the vertical plate 15; a first sliding groove 443 is provided on one side of the traction plate 44, and second sliding grooves 444 are provided on both sides of the first sliding groove 443, and a traction unit 45 is slidably connected to the two second sliding grooves 444, and a traction hole 441 is provided on the top of the traction plate 44. The stop head 411 is connected to the traction unit 45 by a traction rope 43. The traction unit 45 includes a traction slide bar 452 slidably connected to the second slide groove 444. The outer wall of the traction slide bar 452 is fixedly connected to the traction block 451; the outer surface of the traction block 451 is a convex structure in the middle and concave structure on both sides. The traction plate 44 is a quarter arc structure, and its radius is consistent with the rotation radius of the rotating plate 34. Therefore, when the rotating plate 34 rotates, the top end of the rotating plate 34 fits into the surface wall of the traction plate 44, and the bottom end of the traction plate 44 is an outward-turned structure. The workpiece after stamping can be unloaded through the unloading assembly 4 to avoid the workpiece getting stuck at the unloading port and causing damage to the workpiece during subsequent stamping.

[0049] When the punch head 2 is performing the punching work, its output shaft just moves downward, driving the rotary plate 34 to rotate. When the output shaft moves downward to the lowest position, the rotary plate 34 just rotates half a circle to the lowest end. After the punching work is completed, the output shaft starts to move upward, and the output shaft will pull the rotary plate 34 to rotate another half circle. When the rotary plate 34 starts to rotate to a quarter circle, the rotary plate 34 starts to contact the surface of the traction plate 44. As the rotary plate 34 rotates, the rotary plate 34 will drive the traction unit 45 to slide on the second slide groove 444. The sliding traction unit 45 will pull the unloading rod 41 through the traction rope 43, so that the unloading rod 41 at one end of the inner part of the punching die 7 is pulled The unloading rod 41 is pulled into the unloading hole 71 so that the unloading rod 41 will not affect the stamping work. When the rotary piece 34 drives the traction unit 45 to rotate to the bottom end of the traction plate 44, since the bottom end of the traction plate 44 is outward-turned, the rotary piece 34 will squeeze the traction unit 45 into the outward-turned end of the traction plate 44, so that the traction unit 45 and the rotary piece 34 are separated from each other. Without the drive of the rotary piece 34, the return spring 42 will return to its initial state, driving the unloading rod 41 to extend from the unloading hole 71, thereby bouncing the ear tag after stamping to the discharge port 72 for unloading. At the same time, the unloading rod 41 will pull the traction rope 43 to drive the traction unit 45 to return to its initial position.

[0050] like Figure 2 and Figure 12As shown, the material conveyor belt 5 is provided with a number of evenly distributed material placement slots 51, the inner wall of the material placement slot 51 is fixedly connected with a U-shaped material baffle 53, and a slide 52 is provided on one side of the material placement slot 51. When the staff places the ear tag material to be processed, they only need to place the ear tag material to be processed in the adjacent material placement slot 51. As the material processing in the previous material placement slot 51 is completed, the feeding component 3 will drive the material conveyor belt 5 to transmit and transmit the adjacent material placement slot 51 to the bottom of the punching head 2 for punching.

[0051] The working principle of the technical solution provided by the present invention is as follows: when punching and manufacturing ear tags, the staff places the ear tag materials to be processed in the adjacent material placement slots 51 and then starts the punching work of the punch head 2.

[0052] During stamping, when the output shaft of the punching head 2 works up and down, it will drive the fixed tube 31 fixed on its outer wall to work up and down, thereby driving the slide 33 fixedly connected to it to work up and down through the bent rod 32, and then driving the second connecting rod 37 to move up and down through the slide 33, and connecting the second connecting rod 37 to the two rotating plates 34 through the clamping unit 38. Therefore, when the slide 33 drives the second connecting rod 37 to move up and down, the bottom of the second connecting rod 37 will squeeze the clamping unit 38 to drive the rotating plate 34 to rotate in a circle, thereby driving the second rotating rod 36 to rotate, and the rotating second rotating rod 36 drives the roller 6 fixed to it to rotate, thereby driving the roller 6 to rotate, and then drives the material conveyor belt 5 to be transmitted through the roller 6, driving the ear tag material to be processed on the material conveyor belt 5 to move, and as the material processing in the previous material placement slot 51 is completed, the feeding assembly 3 will drive the material conveyor belt 5 to transmit, and transmit the adjacent material placement slot 51 to the bottom of the punching head 2 for stamping.

[0053] When the punch head 2 is performing the punching work, its output shaft just moves downward, driving the rotary piece 34 to rotate. When the output shaft moves downward to the lowest position, the rotary piece 34 just rotates half a circle to the lowest end. After the punching work is completed, the output shaft starts to move upward, and the output shaft will pull the rotary piece 34 to rotate another half circle. When the rotary piece 34 starts to rotate to a quarter circle, the rotary piece 34 starts to contact the surface of the traction plate 44. As the rotary piece 34 rotates, the rotary piece 34 will drive the traction unit 45 to slide on the second slide groove 444. The sliding traction unit 45 will pull the unloading rod 41 through the traction rope 43, so that the unloading rod 41 at one end of the inner part of the punching die 7 is pulled. The pull rod 41 is pulled into the discharge hole 71 so that the discharge rod 41 does not affect the stamping work. When the rotary piece 34 drives the traction unit 45 to rotate to the bottom end of the traction plate 44, since the bottom end of the traction plate 44 is outward-turned, the rotary piece 34 will squeeze the traction unit 45 into the outward-turned end of the traction plate 44, so that the traction unit 45 and the rotary piece 34 are separated from each other. Without the drive of the rotary piece 34, the return spring 42 will return to its initial state, driving the discharge rod 41 to extend from the discharge hole 71, thereby bouncing the ear tag after stamping to the discharge port 72 for unloading. At the same time, the discharge rod 41 will pull the traction rope 43 to drive the traction unit 45 to return to its initial position.

Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.
