Description

Technical Field

[0001] This utility model relates to the field of bag taking and opening of long strip M-shaped kraft paper bags in metal can lid bagging equipment, and particularly to a pull-out bag opening and feeding device. Background Technology

[0002] In recent years, the three-piece can industry has shown a steady growth trend. Three-piece cans are widely used in functional beverages, food and chemical industries. A three-piece can consists of three parts: the can body, the can bottom and the can lid. The can lid is an indispensable part of the production process in various industries. With the increasing demand in beverage, food and chemical industries, improving the production efficiency of traditional can lids is an effective way for can lid manufacturers to increase their product capacity.

[0003] In the traditional metal can lid production process, high-speed punch presses iron sheets into shape, which are then collected by a conveyor line and manually placed into paper bags for packaging. Since manual bagging of metal can lids requires a lot of manpower and involves a large number of repetitive operations, this process is suitable for automation to improve production efficiency. The equipment developed in this patent is suitable for automatic bagging of metal can lids. Utility Model Content

[0026] Reference Figure 1-5This utility model discloses a pull-out bag opening and feeding device, which includes a dual-station bag compartment assembly 1, a swing-type bag picking and opening assembly 2, and a bag supporting and feeding assembly 3. The dual-station bag compartment assembly 1 includes a bag compartment frame 11, and a paper bag placing platform 13 is provided on the upper side of the bag compartment frame 11. The swing-type bag picking and opening assembly 2 is located on the upper right side of the paper bag placing platform 13. A lifting cylinder 12 is fixedly connected to the inner surface of the middle part of the bag compartment frame 11. The output end of the lifting cylinder 12 is fixedly connected to the lower surface of the paper bag placing platform 13. The lifting cylinder 12 facilitates the adjustment of the height of the paper bag. The upper left side of the paper bag placing platform 13... A shifting cylinder 14 is fixedly connected to the surface of the paper bag placement platform 13. Shifting guide rails 15 are provided on both the left and right sides of the platform. Through the shifting cylinder 14 and the shifting guide rails 15, when one bag compartment is empty, the shifting cylinder 14 drives the paper bag placement platform 13 to move the other bag compartment to the lifting position. A paper bag height sensor 17 is fixedly connected to the upper right side of the paper bag placement platform 13, and a paper bag sensor 16 is fixedly connected to the lower surface of the platform. The lifting cylinder 12, shifting cylinder 14, paper bag sensor 16, and paper bag height sensor 17 are all connected to... The external controllers are electrically connected and are all obtained from conventional commercial channels. Their specific structure, working principle, and possible control methods and spatial arrangements can adopt conventional choices in the field and should not be regarded as the innovation of this utility model. This is understandable to those skilled in the art. This utility model patent will not elaborate further. The swing bag opening component 2 includes a swing mounting plate 21. A swing drive cylinder 22 is provided on the right side of the swing mounting plate 21. The output end of the swing drive cylinder 22 is fixedly connected to the outer surface of the right side of the swing mounting plate 21. The lower side of the swing mounting plate 21 is provided with A bag-picking lifting cylinder 23 is provided, and a bag-picking vacuum suction cup 24 is fixedly connected to the output end of the bag-picking vacuum suction cup 23. A lower bag-suction vacuum suction cup 25 is provided on the lower side of the bag-picking vacuum suction cup 24. The bag-picking lifting cylinder 23 drives the bag-picking vacuum suction cup 24 to move downward. The bag-picking vacuum suction cup 24 sucks up the paper bag by the suction force generated by the vacuum generator. Then, the swing drive cylinder 22 will place the bag-picking vacuum suction cup 24 and the paper bag above the lower bag-suction vacuum suction cup 25. At this time, the bag-picking lifting cylinder 23 extends again and, together with the lower bag-suction vacuum suction cup 25, opens the paper bag up and down under the suction force generated by the vacuum generator to complete the action.

[0027] The bag-supporting and feeding assembly 3 includes a bag-feeding translation rodless cylinder 31 and a bag-supporting assembly 32. The bag-supporting assembly 32 is slidably connected to the lower surface of the bag-feeding translation rodless cylinder 31. A lower bag-supporting arc plate 3211 is fixedly connected to the lower side of the bag-supporting assembly 32. The bag-supporting assembly 32 includes a lower bag-supporting cylinder 321. A lower bag-supporting block 3212 is fixedly connected to the output end of the lower bag-supporting cylinder 321. The lower bag-supporting block 3212 is driven by the lower bag-supporting cylinder 321 to lift and press the paper bag to complete the bag-supporting action. The bag-supporting assembly 32 also includes an upper bag-supporting cylinder 322. An upper bag-supporting arc plate 3221 is fixedly connected to the output end of the upper bag-supporting cylinder 322. The upper bag-supporting arc plate 3221 matches the lower bag-supporting arc plate 3211.

[0028] Working principle: When in use, paper bags are placed in the paper bag placement platform 13. The paper bag height sensor 17 senses the height of the paper bag. When the paper bag is lower than the height of the paper bag height sensor 17, the lifting cylinder 12 will lift the paper bag to the specified height. When the paper bags in one bag compartment are used up, the paper bag sensor 16 will send a signal, and the shift cylinder 14 will drive the paper bag placement platform 13 to send another bag compartment to the lifting position.

[0029] When the bag is picked up, the swing drive cylinder 22 extends, the bag picking lifting cylinder 23 extends, and the bag picking vacuum suction cup 24 uses the suction force generated by the vacuum generator to hold the paper bag. After the bag is picked up, the bag picking lifting cylinder 23 retracts. Then the swing drive cylinder 22 will place the bag picking vacuum suction cup 24 and the paper bag above the lower bag suction cup 25. At this time, the bag picking lifting cylinder 23 extends again and, together with the lower bag suction cup 25, opens the paper bag up and down under the suction force generated by the vacuum generator to complete the action, waiting for the bag forming mechanism to feed the bag.

[0030] After the bag opening assembly 2 completes the bag opening action, the bag feeding and conveying assembly 3's rodless cylinder 31 extends the bag opening assembly 32 into the paper bag. The upper bag opening tightening cylinder 322 pushes the upper bag opening arc plate 3221 upward, and the lower bag opening pressing cylinder 321 lifts the lower bag opening pressing block 3212 to press the paper bag, completing the bag opening action. After the bag opening action is completed, the rodless cylinder 31 delivers the paper bag to the bagging position, completing all the actions of this assembly.
