Description

Technical Field

[0001] The utility model relates to the technical field of easy-open lids, in particular to a punching machine for producing and processing easy-open lids. Background Art

[0002] Easy-open lids, also known as easy-open lids, are used for canned food sealing and opening. They are defined as lids that are pre-engraved with a certain depth of score lines and riveted with pull rings, and can be safely torn open along the score lines when opened. They are metal packaging products. They are mostly made of aluminum or tinplate, and come in a variety of sizes, suitable for iron cans, aluminum cans, composite cans, PET plastic cans, and paper cans.

[0003] Easy-open lids are generally formed by stamping, and stamping refers to a processing method in which pressure and molds are used to apply external force to plates, strips, tubes and profiles to cause plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. The punching machine used for the production and processing of easy-open lids is a device for stamping easy-open lids.

[0004] After searching, it is proposed in a patent publication number CN220635970U that "the utility model adds a linkage rod and a spring block to the easy-open lid stamping device, so that the easy-open lid can be quickly picked out from the stamping lower die after being ejected by stamping, thereby effectively improving the working efficiency of the easy-open lid stamping device";

[0005] However, the above scheme still has certain shortcomings in actual use. This scheme is to perform stamping operations by placing the material to be stamped between the stamping upper die and the stamping lower die. However, the stamping of the material is bound to produce a certain amount of waste. After the stamping operation exerts a large pressure on the material, uneven force will be generated at various points on the surface of the material, which can easily cause the waste to fly out of the working area in an undirected manner during the processing. In addition, no protective structure is provided in this scheme, resulting in the flying waste posing a threat to the personal safety of the staff, making the use of the punch press less safe.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model discloses a punching machine for producing and processing easy-open lids, comprising a processing table 1, a punching device 2 and a mounting back plate 3 are fixedly mounted on the top of the processing table 1, a protective structure 4 is fixedly mounted on the front side of the mounting back end, and the protective structure 4 is located above the punching device 2.

[0022] The punching device 2 includes a placement plate 201 , a punching machine 202 and a punching lower die 204 are arranged on the top of the placement plate 201 , a punching upper die 203 is arranged on the movable end of the punching machine 202 , and the punching upper die 203 is located directly above the punching lower die 204 .

[0023] The protective structure 4 includes a driving box 401 and a protective cover shell 402, the driving box 401 and the protective cover shell 402 are slidably connected, the inner wall of the driving box 401 is connected to a follower gear 404 and a driven gear 405 through a driving motor 403, a rotating disk 406 is fixedly installed at the center of the driven gear 405, and two overlapping rods 407 are fixedly connected to the front side of the rotating disk 406, and a lifting block 409 is slidably connected to the inner wall of the driving box 401. A lap plate 411 is fixedly connected to one side of 409, and a lap rod 407 close to the outside of the turntable 406 is in contact with the lap plate 411. A connecting rod 412 is fixedly connected to the other side of the lifting block 409, and the other end of the connecting rod 412 is fixedly connected to the inner wall of the protective cover shell 402 through the connecting rod 412. A through hole 413 is opened on the side of the drive box 401, and one end of the connecting rod 412 away from the lifting block 409 extends to the outside of the drive box 401 through the through hole 413.

[0024] By setting up the protective structure 4, the driving box 401 motor inside the driving box 401 is used to drive the passive gear 405 to drive the overlapping rod 407 on the front side of the turntable 406 to perform circular motion through the follower gear 404, so that the two overlapping rods 407 can alternately contact the overlapping plates 411, and the overlapping plates 411 are driven by the overlapping rods 407 to drive the protective cover shell 402 to gradually cover the outside of the stamping device 2 through the connecting rod 412 on the outside of the lifting block 409, so that the protective cover shell 402 can protect the material, thereby preventing waste from flying out when the stamping machine 202 is working, and providing protection for the personal safety of the staff.

[0025] Specifically, a slide bar 408 is fixedly mounted on the inner wall of the driving box 401 , and the surface of the slide bar 408 is slidably connected to the inner wall of the lifting block 409 .

[0026] In this embodiment, the lifting block 409 can slide along the surface of the sliding rod 408, thereby improving the movement stability of the lifting block 409.

[0027] Specifically, a damping spring 410 is disposed at the bottom end of the lifting block 409 , and the bottom end of the damping spring 410 is connected to the inner wall of the driving box 401 .

[0028] In this embodiment, in the gap between the alternating rotations of the two overlapping rods 407, the automatic rebound resilience of the damping spring 410 can be used to make the lifting block 409 rebound to the initial position automatically, so that the lifting block 409 can drive the protective cover shell 402 to rebound to the initial position automatically.

[0029] When in use, the material is first placed in the stamping lower die 204, and then the protective structure 4 is started, so that the driving motor 403 inside the driving box 401 starts to drive the left follower gear 404 to rotate, and the left follower gear 404 will drive the right follower gear 404 to mesh transmission, and the rotation of the two follower gears 404 will drive the passive gears 405 on both sides to rotate, and the rotation directions of the two follower gears 404 are opposite, so that the two follower gears 404 drive the two turntables 406 to rotate relative to each other, so that the turntable 406 on the left will rotate counterclockwise, and the turntable 406 on the right will rotate clockwise;

[0030] The rotation of the turntable 406 will drive the two overlapping rods 407 on the same turntable 406 to perform circular motion, and the circular motion of the two overlapping rods 407 will alternately contact the overlapping plates 411, so that the overlapping rods 407 will press down the overlapping plates 411, causing the overlapping plates 411 to drive the connecting rods 412 to descend along the through openings 413 through the lifting blocks 409, so that the two connecting rods 412 jointly drive the protective cover shell 402 to gradually overlap with the top of the processing table 1;

[0031] During the process of the protective cover 402 descending, the punching device 2 will be gradually covered in all aspects, so that the material inside the punching device 2 will also be sealed inside the protective cover 402;

[0032] Then, the punching machine 202 is started, so that the movable end of the punching machine 202 drives the upper punching die 203 to descend, so that the upper punching die 203 begins to punch the material in the lower punching die 204, causing the material to be punched into an easy-open lid state.

[0033] To summarize, the punching machine for producing and processing easy-open lids, by setting up a protective structure 4, utilizes the driving box 401 motor inside the driving box 401 to drive the passive gear 405 to drive the overlapping rod 407 on the front side of the turntable 406 to perform circular motion through the follower gear 404, so that the two overlapping rods 407 can alternately contact the overlapping plates 411, and the overlapping plates 411 are driven by the overlapping rods 407 to drive the protective cover shell 402 to gradually cover the outside of the punching device 2 through the connecting rod 412 on the outside of the lifting block 409, so that the protective cover shell 402 can protect the material, thereby preventing waste from flying out when the punching machine 202 is working, and providing protection for the personal safety of the staff.
