Description

Technical Field

[0001] This invention relates to the field of easy-open lid manufacturing technology, specifically to an easy-open lid multi-channel stamping, edge-rolling, and glue-injection production line. Background Technology

[0002] Easy-open lids, also known as pull-tab lids, are used in the food canning industry for sealing and opening metal cans. These lids have pre-etched grooves of a certain depth on the surface during manufacturing and are riveted with a pull ring to allow for safe tearing along the grooves. The grooves typically follow a similar shape to the lid itself, being equidistant lines pointing inwards. Therefore, whether the easy-open lid is round or irregularly shaped, the grooves will resemble the lid's shape. The main function of easy-open lids is sealing and barrier, preventing liquid evaporation and corrosion or contamination of the workplace by external air or debris. They also effectively extend the product's shelf life. Furthermore, easy-open lids play an important role in aesthetic packaging; a good pull-tab easy-open lid can enhance the overall appearance and quality of the packaging.

[0003] Currently, the production of easy-open lids involves multiple processes, including stamping, edge rounding, and sealant application. After one process is completed, workers need to move the finished lids to the next processing location, which reduces production efficiency and increases labor input. Furthermore, after stamping and rolling the edges, workers need to flip multiple lids to facilitate subsequent glue application, further increasing their workload. In the process of applying glue to the surface of the lids, manual glue gun application is mostly used, which not only fails to guarantee the glue quality of each lid but also results in low production efficiency, hindering efficient production operations.

[0032] The lifting structure 5 includes a lifting frame 51, a first motor 52, a first lead screw 53, a first connecting block 54, a guide rail 55, and a guide block 56. The lifting frame 51 is located on the right side of the support frame 4. The first motor 52 is fixed to the top of the lifting frame 51. The first lead screw 53 is rotatably connected inside the lifting frame 51, and the top end of the first lead screw 53 is fixedly connected to the output shaft of the first motor 52. The first connecting block 54 is fixed to the right side surface of the support frame 4, and the first lead screw 53 passes through the first connecting block 54 and is threadedly connected to the first connecting block 54. The guide rail 55 is fixed to the front and rear sides of the left side of the lifting frame 51. Guide blocks 56 are fixed to the front and rear sides of the right side of the support frame 4, and the guide rail 55 passes through the guide block 56. Block 56 is slidably connected to the inner wall of guide block 56, and the bottom of lifting frame 51 is fixedly connected to the top of first electric slide rail 6. When the worker places the easy-open cover material to be processed on the surface of the feeding plate 8, the worker can turn on the first motor 52, so that the output shaft of the first motor 52 drives the first lead screw 53 below to rotate. The first lead screw 53 is threadedly connected to the first connecting block 54, and the guide rails 55 on both sides limit the lifting frame 51 as a whole, so that the lifting frame 51 pushes the first electric slide rail 6 below to fall, so that the vacuum suction cup 7 approaches the easy-open cover material, and opens the vacuum suction cup 7 to adsorb and fix the easy-open cover material so that the easy-open cover material can be stamped.

[0033] The unloading structure 10 includes a fixed frame 101, a drive motor 102, a first threaded rod 103, a threaded sleeve 104, and a lifting rod 105. The fixed frame 101 is fixed to the rear side of the top of the placement platform 3. The drive motor 102 is fixed to the left side of the inner wall of the fixed frame 101. The first threaded rod 103 is rotatably connected to the right side of the inner wall of the fixed frame 101, and the left end of the first threaded rod 103 is fixedly connected to the output shaft of the drive motor 102. The threaded sleeve 104 is threadedly connected to the right side of the surface of the first threaded rod 103. The lifting rod 105 is hinged to the top of the threaded sleeve 104. The top of the lifting rod 105 is hinged to the bottom of the feeding plate 8. After the easy-open cover is stamped and placed on the feeding plate 8, the operator can open the drive motor 102 below, which will cause the first threaded rod 103 to rotate. The threaded sleeve 104 will drive the lifting rod 105 above to move, so that the lifting rod 105 pushes the feeding plate 8 above to move, so that the left side of the feeding plate 8 is lifted. The easy-open cover material that has been processed on the surface of the feeding plate 8 will slide into the storage box 11 on one side, so that the operator can perform subsequent edge rolling processing on the easy-open cover material.

[0034] A limiting groove 28 is provided on the lower part of the inner wall of the fixed frame 101. A limiting rod 29 is fixed to the bottom of the threaded sleeve 104. The bottom end of the limiting rod 29 extends into the interior of the limiting groove 28 and is bolted with a limiting block 30. The limiting block 30 is slidably connected to the inner wall of the limiting groove 28. When the first threaded rod 103 rotates, the lower limiting block 30 limits the upper threaded sleeve 104 through the limiting rod 29, so that the threaded sleeve 104 can only move horizontally left and right on the surface of the first threaded rod 103, so that the lifting rod 105 can push the upper feeding plate 8 to move.

[0035] The clamping structure 16 includes a second motor 161, a fixed platform 162, a rotating ring 163, a second connecting block 164, and a first movable block 165. The second motor 161 is fixed to the top of the support platform 15, the fixed platform 162 is fixed above the second motor 161, the rotating ring 163 is fixed to the surface of the output shaft of the second motor 161, the second connecting block 164 is rotatably connected to both sides of the surface of the rotating ring 163, and the second connecting block 164 is generally arc-shaped. The first movable block 165 is rotatably connected to the surface above the second connecting block 164, and the clamping plate 17 is fixed. Above the first movable block 165, after the worker stamps the easy-open lid material, the worker can place the stamped easy-open lid material between the clamping plates 17. Then the worker opens the second motor 161 below, which causes the output shaft of the second motor 161 to drive the rotating ring 163 above to rotate. The second connecting blocks 164 on both sides move accordingly, and the clamping plates 17 on both sides move towards each other, thereby clamping and fixing the bottom position of the easy-open lid material, so that the edge-rolling device 13 above can roll the top side position of the easy-open lid material.

[0036] The top of the fixed platform 162 is bolted with a limiting rail 31. The surface of the first movable block 165 is provided with a through groove 32, and the limiting rail 31 passes through the through groove 32 and slides through the inner wall of the through groove 32. When the rotating ring 163 rotates, the limiting rail 31 will limit the first movable block 165, so that the first movable blocks 165 on both sides can only move in opposite directions, so as to clamp and fix the easy-open material.

[0037] The flip-top structure 22 includes a third motor 221, a rotating rod 222, a cylinder 223, and a clamping rod 224. The third motor 221 is fixed to the right side surface of the movable frame 21. The rotating rod 222 passes through one side of the movable frame 21 and is rotatably connected to the movable frame 21. The right end of the rotating rod 222 is fixedly connected to the output shaft of the third motor 221. The cylinder 223 is fixed to the surface of the rotating rod 222, and there are several cylinders 223. The clamping rod 224 is fixed to the output shaft of the cylinder 223. On both sides of the output shaft, and on the surface of the clamping rod 224, there are arc-shaped grooves. The arc-shaped grooves on the surface of the clamping rod 224 are used in conjunction with the easy-open cover. When the easy-open cover material after stamping and rolling is on the surface of the conveyor belt 18, the operator can open the cylinder 223 to make the clamping rods 224 on both sides move towards each other to clamp the easy-open cover material. At the same time, the third motor 221 is turned on, causing the rotating rod 222 to rotate and drive the easy-open cover material to flip over as a whole, so that the easy-open cover material can be used for subsequent glue injection operation.

[0038] The adhesive application structure 25 includes a fourth motor 251, a planetary gear box 252, a rotating disk 253, and an adhesive application nozzle 254. The fourth motor 251 is fixed to the right side of the top of the support platform 24, the planetary gear box 252 is fixed to the left side of the top of the support platform 24, and the output shaft of the fourth motor 251 passes through the interior of the planetary gear box 252. The rotating disk 253 is located on the left side of the bottom of the support platform 24, and a rotating shaft is fixed to the top of the rotating disk 253, with the top end of the rotating shaft passing through the interior of the planetary gear box 252. The adhesive application nozzle 254 is fixed... The adhesive nozzle 254 is positioned on the left side of the support platform 24, and a flexible hose for adhesive to pass through is connected to the top of the nozzle. After the operator turns on the fourth motor 251, the output shaft of the fourth motor 251 drives the rotating disk 253 below to rotate through the planetary gear box 252. This causes the rotating disk 253 to rotate the easy-open lid material. As the rotating disk 253 rotates, the adhesive enters the interior of the adhesive nozzle 254. The adhesive nozzle 254 applies the adhesive to the surface of the easy-open lid material below, and the adhesive is evenly applied as the easy-open lid material rotates.

[0039] The positioning structure 27 includes a mounting platform 271, a hydraulic cylinder 272, a second movable block 273, a connecting plate 274, and a positioning wheel 275. The mounting platform 271 is fixed to the left side of the top of the workbench 23. The hydraulic cylinder 272 is fixed to the rear side of the mounting platform 271, and the output shaft of the hydraulic cylinder 272 passes through the mounting platform 271 and is slidably connected to it. The second movable block 273 is fixed to the front end of the output shaft of the hydraulic cylinder 272. The connecting plate 274 is embedded in the top of the second movable block 273, and the positioning wheel 275 is rotatably connected to the front side of the top of the connecting plate 274. When the easy-open lid material is placed above the rotating disk 26, the operator can open the hydraulic cylinder 272. The output shaft of the hydraulic cylinder 272 pushes the second movable block 273 to move, and the connecting plate 274 drives the positioning wheel 275 to move forward, so that the positioning wheel 275 contacts the side of the easy-open lid material. When the easy-open lid material rotates, the positioning wheel 275 can position and guide the easy-open lid material to prevent glue from being applied to other positions.

[0040] Guide rods 35 are fixed on both the left and right sides of the inner wall of the mounting platform 271. The guide rods 35 pass through the second movable block 273 and are slidably connected to the second movable block 273. When the second movable block 273 moves in the back and forth direction, the guide rods 35 on both sides can guide the second movable block 273 and improve the guiding stability of the positioning wheel 275.

[0041] Working Principle: When processing easy-open cans, the worker first places the raw material on the feeding plate 8 above the placement table 3. Then, the worker turns on the first motor 52, causing the first electric slide rail 6 to lower the vacuum suction cup 7. The worker then opens the vacuum suction cup 7, allowing it to pick up the raw material. Subsequently, the first motor 52 causes the first electric slide rail 6 to raise the vacuum suction cup 7 again. The worker then opens the first electric slide rail 6, pushing the vacuum suction cup 7 onto the stamping die above the stamping processing table 1. The worker then closes the vacuum suction cup 7, causing the raw material below it to fall onto the die surface. Finally, the worker controls the first electric... The slide rail 6 moves the vacuum suction cup 7 back to its original position. The operator opens the stamping equipment 2 and stamps the easy-open lid material. Then, the operator uses the first electric slide rail 6 and the vacuum suction cup 7 to suck the easy-open lid material from above the mold and place it back onto the surface of the feeding plate 8. The drive motor 102 under the feeding plate 8 is turned on, causing the feeding plate 8 to tilt and pour the easy-open lid material into the storage box 11. The operator can then stamp the easy-open lid material to be processed later on the feeding plate 8. The operator takes out the easy-open lid material from the storage box 11 and places it between the clamping plates 17. By turning on the second motor 161 below, the clamping plates 17 clamp and fix the easy-open lid material. The second electric slide rail 102... 4. Opening the platform 15 causes the easy-open lid material to move upwards. The operator opens the edge-rolling device 13 and rolls the edge of the upper surface of the easy-open lid material. The operator places the rolled easy-open lid material on the surface of the conveyor belt 18. When the rolled easy-open lid material is conveyed above the conveyor belt 18, the operator first opens the third electric slide rail 20, which causes the third electric slide rail 20 to move the movable frame 21 backwards. Then, the operator opens the lifting platform 19, causing the movable frame 21 to fall down, which causes the clamping rods 224 to approach the easy-open lid material on the surface of the conveyor belt 18. When the easy-open lid material is between the clamping rods 224, the operator can then open the cylinder 223. The cylinder 223 retracts when the cylinder is opened, causing the clamping rods 224 on both sides to clamp the easy-open lid material. Once clamping is complete, the lifting platform 19 opens again, raising the movable frame 21. Then, the operator activates the third motor 221, causing its output shaft to rotate the rotating rod 222, which in turn causes the clamping rods 224 to flip the easy-open lid material. The third electric slide rail 20 then opens again, pushing the clamping rods 224 forward so that the easy-open lid material is above the conveyor belt 18. The lifting platform 19 then opens again, lowering the movable frame 21. Finally, the operator activates the cylinder 223, causing the clamping rods 224 to release the easy-open lid material.The flipped easy-open lid material falls onto the surface of conveyor belt 18, completing the flipping operation for multiple easy-open lid materials. After flipping, the operator places the material above rotating disk 26. Then, the operator opens the lower hydraulic rod 33, causing the lifting block 34 to push rotating disk 26 upwards, bringing the easy-open lid material on the surface of rotating disk 26 into contact with the upper rotating disk 253. Next, the operator opens one side hydraulic cylinder 272, causing positioning wheel 275 to contact the side of the easy-open lid material. Then, the operator turns on the fourth motor 251 and injects glue into the glue spray nozzle 254. Rotating disk 26 also rotates, and glue spray nozzle 254 evenly sprays glue onto the edge of the upper surface of the easy-open lid material. Finally, hydraulic rod 33 controls rotating disk 26 to fall, allowing the operator to remove the easy-open lid material, thus completing the stamping, curling, and glue injection operations for the easy-open lid.
