Description

Technical Field

[0001] This utility model relates to a working device on auxiliary equipment of a bag making machine, and in particular to a material feeding mechanism for a stacking and collecting device of a plastic film bag making machine. It is suitable for stacking and collecting foamed film bags and bubble wrap bags. Background Technology

[0002] Existing plastic film bag making machines have various stacking and receiving devices, such as the receiving device for a bag making machine disclosed in Chinese Patent No. 201921214606.X, which includes: a feeding mechanism, including a material platform mounted on the machine frame, the material platform being equipped with a feeding device for delivering finished products to a designated position; a lifting device connected to the material platform, the lifting device being used to drive the material platform to move up and down; a blocking device, including a fixed frame, a baffle plate, and a cylinder, the fixed frame being fixed to the material platform, the cylinder being fixed to the fixed frame, and the baffle plate being fixed to the cylinder and its bottom contacting the feeding device; and a pressure plate. The pressure plate is connected to the baffle and is located above the feeding device. The lifting device drives the material platform, thereby driving the feeding device to gradually descend. The finished products fed to the feeding device are stacked at the blocking point. When the stack of finished products reaches a set quantity, the cylinder drives the baffle and pressure plate to rise, and at the same time, the feeding device sends the finished products to the bottom of the pressure plate. Then, the cylinder drives the baffle and pressure plate to fall, and the pressure plate presses down on the stacked finished products, which are then manually bundled and packaged. Then, the lifting device drives the material platform, thereby driving the feeding device to rise back to its original position, and then the blocking device controls the baffle to descend to its original position, repeating the cycle. However, when this plastic film bag making machine's stacking receiving device receives foamed film bags and bubble wrap bags, the bags often shift due to loose contact between them when stacking, resulting in unevenly bundled bags. If a cylinder mechanism is used to directly compact the gaps between the bags, the excessive travel of the cylinder mechanism's telescopic rod will affect the bag-tapping frequency, thus reducing work efficiency. Summary of the Invention

[0003] In order to overcome the problems of uneven bundling of stacked bags when receiving foamed film bags and bubble wrap bags in the existing technology, and the reduced work efficiency caused by directly compacting the gaps between bags with a cylinder mechanism, the purpose of this utility model is to provide an improved material tapping mechanism for the stacking and receiving device of a plastic film bag making machine, which can overcome the defects of the existing technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a material tapping mechanism for a stacking and collecting device of a plastic film bag making machine, characterized in that: it includes several material tapping plates, a material tapping plate frame, a left lifting rod, a right lifting rod, a left plate seat, a right plate seat, a left lever plate, a right lever plate, a left cylinder, and a right cylinder; wherein the several material tapping plates are evenly distributed and fixed on the material tapping plate frame, and the left plate seat and right plate seat are respectively installed and fixed on the left and right sides of the frame in front of the material blocking device of the plastic film bag making machine; the left lever plate and right lever plate are respectively rotatably fitted on the left plate seat and right plate seat by their rotation fulcrum; the left cylinder and right cylinder are respectively installed and fixed on the left lever plate and right lever plate; one end of the left lever plate is provided with a left first sliding groove, and the other end is provided with a left second sliding groove; one end of the right lever plate is provided with a right first sliding groove, and the other end is provided with a... There is a right second slide groove; the upper end of the left lifting rod is fixed to the left end of the material-tapping plate frame, the middle part slides vertically on the left plate seat, and the lower end slides and rotates on the left first slide groove; the outer end of the telescopic rod of the left cylinder slides and rotates on the left second slide groove; the upper end of the right lifting rod is fixed to the right end of the material-tapping plate frame, the middle part slides vertically on the right plate seat, and the lower end slides and rotates on the right first slide groove; the outer end of the telescopic rod of the right cylinder slides and rotates on the right second slide groove; the length of the left lever plate, with its rotation fulcrum as the boundary, is greater than the length of the left second slide groove; the length of the right lever plate, with its fulcrum as the boundary, is greater than the length of the right first slide groove.

[0005] The left lifting rod, as described in the above technical solution, has its middle portion vertically slidingly engaged with the left plate seat. This can be achieved by the left sliding block of the middle portion of the left lifting rod slidingly engaged with the left vertical slide rail of the left plate seat, or by the left slide rail block of the middle portion of the left lifting rod slidingly engaged with the left vertical sliding groove of the left plate seat. Similarly, the right lifting rod, with its middle portion vertically slidingly engaged with the right plate seat, can have its right sliding block of the middle portion of the right lifting rod slidingly engaged with the right vertical slide rail of the right plate seat, or by the slide rail block of the middle portion of the right lifting rod slidingly engaged with the right vertical sliding groove of the right plate seat.

[0006] The left lever plate and the right lever plate described in the above technical solution are rotatably fitted on the left plate seat and the right plate seat respectively by their rotation fulcrum, or they can be rotatably fitted on the fixed shaft of the left plate seat and the right plate seat.

[0007] The above technical solution describes a mechanism where the lower end of the left lifting rod slides and rotates on the left first slide groove, the outer end of the telescopic rod of the left cylinder slides and rotates on the left second slide groove, the lower end of the right lifting rod slides and rotates on the right first slide groove, and the outer end of the telescopic rod of the right cylinder slides and rotates on the right second slide groove. This can be achieved by having horizontal shafts on the ends of the lower ends of the left and right lifting rods and the outer ends of the telescopic rods of the left and right cylinders, respectively. Rollers are mounted on these horizontal shafts, and the rollers slide and rotate on the left first slide groove, left second slide groove, right first slide groove, and right second slide groove, respectively.

[0008] Each of the aforementioned material-pressing plates can be equipped with a position adjuster. The position adjuster consists of a sliding sleeve located on the top side of the material-pressing plate and a hand-tightening set screw threaded onto the sliding sleeve. The sliding sleeve is slidably fitted onto the material-pressing plate frame, and the screw end of the hand-tightening set screw engages with the material-pressing plate frame for locking or releasing. The position adjuster is used to adjust the position of the material-pressing plate on the material-pressing plate frame.

[0009] The beneficial effects of this utility model are as follows: First, by setting this patting mechanism in front of the material blocking device of the stacking and receiving device of the plastic film bag making machine, the patting mechanism compacts each foam film bag and bubble wrap bag when the stacking and receiving device receives and stacks them, eliminating the phenomenon of loose contact between the stacked bags. This prevents the bags from shifting during the process of moving to the next work station for bundling and packaging, resulting in neat and uniform bags after stacking and bundling. Second, the specific design of this patting mechanism allows the telescopic rods of the left and right cylinders to have a shorter driving stroke, while achieving a larger running distance for the left and right lifting rods. Due to the shorter driving stroke of the cylinder telescopic rods, the patting frequency of the patting plate can be higher, thereby effectively improving work efficiency.

[0020] When working, refer to Figures 1-3When the plastic film bag making machine automatically throws the finished foamed film bags or bubble wrap bags one by one onto the receiving point 29 in front of the material blocking device 13 on the stacking and receiving device 12 of the plastic film bag making machine, they are stacked one by one within the area defined by the baffle and limiting side plate (not shown) of the material blocking device 13; each time a bag is stacked, the control circuit on the stacking and receiving device 12 of the plastic film bag making machine controls the high-pressure air valve to open the upward passage and close the downward passage, driving the outer ends 18 of the telescopic rods of the left cylinder 10 and the right cylinder 11 to move upward, passing through the left lever plate 8 and the right lever The lever 9 swings around the pivot point 14, driving the left lifting lever 4 and the right lifting lever 5 downwards. This, in turn, drives the patting plate 2 via the patting plate frame 3 to press down on the top surface of the stacked bags, eliminating any loose contact between the stacked bags. Then, the control circuit on the plastic film bag making machine's stacking and receiving device 12 controls the high-pressure air valve to open the downward channel and close the upward channel, driving the outer ends 18 of the telescopic rods of the left cylinder 10 and the right cylinder 11 downwards. At this time, the patting plate frame 3 drives the patting plate 2 upwards, allowing the next bag to enter the defined area for stacking. This cycle repeats continuously. When the receiving point 29 receives stacked bags one by one, the receiving surface of the receiving point 29 gradually and automatically descends, ensuring that the working height of the topmost bag in each stack is always the same. The principle of this gradual automatic descent can be understood by referring to the publication of the applicant's earlier Chinese Utility Model Patent No. CN218704171U.
