Description

Technical Field

[0001] The utility model relates to the technical field of easy-open lids, in particular to an easy-open lid forming and discharging mechanism. 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] The main forming process of the easy-open cover is to press the easy-open cover sheet into shape through a mold, completing the processes of forming, extrusion sealing and stamping of the easy-open cover, and finally making the finished product after steps such as packaging, sterilization and boxing.

[0004] After searching, it is found that in a device for forming and discharging easy-open lids with the patent publication number CN219525393U, it is stated that "the utility model can make the iron easy-open lids more neat after being formed and discharged through the coordination between the structures, which is convenient for the packing personnel to pick up and improves the packing efficiency";

[0005] However, the above scheme still has certain shortcomings in actual use. In this scheme, the pull-open lid is arranged horizontally in the chute to complete the discharging process, but the scheme does not provide a limiting structure, resulting in the pull-open lid having to rely on the lateral force of the baffle to complete the limiting support of the pull-open lid. However, this limiting method is not stable enough and the pull-open lid may fall over, resulting in the problem of poor stability in the discharging process of the pull-open lid.

[0022] A control panel is fixedly mounted on the top of the placement table 1 , and the control panel is electrically connected to the discharging device 2 and the abutment structure 3 , respectively.

[0023] The discharging device 2 includes a discharging channel 201 and a conveyor belt structure 202 . The conveyor belt structure 202 is located in the gap inside the discharging channel 201 . A through opening 203 is formed on the inner wall of the discharging channel 201 .

[0025] The limiting structure 4 includes a torsion spring hinge seat 401, the inner side of the torsion spring hinge seat 401 is rotatably connected to a limiting arc plate 402, the outer side of the torsion spring hinge seat 401 is fixedly installed with an external pull rod 403, the outer side of the through-hole 203 is fixedly connected with an external limiting block 404, and the external pull rod 403 passes through the through-hole 203 and is inserted into the interior of the external limiting block 404.

[0026] By setting up a discharging device 2 and a limiting structure 4, the conveyor belt structure 202 included in the discharging device 2 can drive the easy-open lid located inside the discharging channel 201 for rapid transportation, and the torsion spring hinge seat 401 included in the limiting structure 4 can drive the limiting arc plate 402 to always assist in fitting with the side end of the easy-open lid located inside the discharging channel 201, so that the easy-open lid to be discharged is limited between the discharging channel 201 and the two limiting arc plates 402, so that the easy-open lid can be stably discharged horizontally in a standing position, thereby avoiding the easy-open lid from tipping over during the discharging process, and significantly improving the stability of the easy-open lid discharging process.

[0027] Specifically, a slide rail 305 is fixedly installed on the top of the placement table 1 , and a slider 306 is slidably connected inside the slide rail 305 . The slider 306 is fixedly connected to an end of the moving frame 303 away from the threaded block 302 .

[0028] In this embodiment, the slider 306 can slide along the inside of the slide rail 305 along with the moving frame 303 , thereby improving the moving stability of the moving frame 303 .

[0029] Specifically, the outer pull rod 403 and the outer limit block 404 are provided with limit holes 406 inside, and the outer pull rod 403 and the outer limit block 404 are movably connected by a limit pin 405 and the limit hole 406 .

[0030] In this embodiment, the limiting pin 405 is inserted into the limiting hole 406 , thereby completing the limiting process for the torsion spring hinge seat 401 .

[0031] When in use, the easy-open lid is sent into the discharge channel 201 through the external structure, so that the easy-open lid is pressed against the abutment plate 304, and then the outer pull rod 403 is pulled, so that the outer pull rod 403 slides inside the external limit block 404, so that the outer pull rod 403 can drive the torsion spring hinge seat 401 to move in an arc in the discharge channel 201, so that the torsion spring hinge seat 401 can drive the relative position between the limit arc plate 402 and the discharge channel 201 to change, and then the limit pin 405 is inserted into the limit hole 406, thereby completing the limit processing of the torsion spring hinge seat 401;

[0032] At this time, the limiting arc plate 402 inside the torsion spring hinge seat 401 can automatically fit on the side end of the easy-open lid according to the automatic resilience of the torsion spring, so that the easy-open lid to be discharged is limited between the discharge channel 201 and the two limiting arc plates 402;

[0034] As the open lids are continuously fed in, the backward speed of the resistance plate 304 matches the speed at which the conveyor belt structure 202 drives the open lids to move, so that the open lids always remain in a vertical state. As a result, the cylinder formed by the accumulation of open lids moves back in an orderly manner in the discharge channel 201, which can make the open lids more neat after being formed and discharged, making it easier for packers to pick them up, thereby improving packaging efficiency.
