Description

Technical Field

[0001] This application relates to the field of round paper drum packaging technology, and in particular to an automatic bagging machine for round paper drums. Background Technology

[0002] A bagging machine, also known as a shrink packaging machine, is a machine that wraps products with heat-shrink film and then heats it to shrink the film and wrap the product.

[0003] For example, Chinese patent application number CN202011389728.X discloses a bagging machine, including a support frame; a detection device connected to the support frame for detecting container bags; a cutting device connected to the support frame for cooperating with the detection device to cut the container bags; an opening device slidably connected to the support frame vertically for opening the container bags and sliding vertically to cover the opened container bags onto the container; and a bag-pressing device disposed above the opening device for pressing the container bags covered on the container into the container; the cutting device, the detection device, the opening device, and the bag-pressing device are arranged sequentially from top to bottom.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] When using common bagging machines to package large items such as round paper drums, the film needs to be conveyed by multiple conveyor rollers during the gradual unfolding process, which makes the film prone to static electricity. When the film comes into contact with or is close to the round paper drum, this static electricity can easily interfere with the normal operation of devices such as film cutting, film spreading, and film welding, which can easily lead to jamming or even machine stoppage, thus hindering efficient operation.

The film guiding rollers 5 are located directly above the film unwinding roller 4. A film conveying roller group 6 and a drive mechanism 7 are provided at the middle of the top of the stand 3. The drive mechanism 7 is used to drive the film conveying roller group 6 to rotate and clamp the film for downward conveying. An electrostatic elimination mechanism 8 is also provided at the top of the stand 3. The electrostatic elimination mechanism 8 is located directly above the film conveying roller group 6 and is used to eliminate static electricity from the film clamped by the film conveying roller group 6. The film unwinding roller 4, the film guiding roller 5, the film conveying roller group 6, and the electrostatic elimination mechanism 8 are all arranged along the length of the paper drum conveyor line 2.

[0039] In this embodiment, mounting plates 9 are provided on both sides of the top of the support frame 3. The two ends of the film conveying roller group 6 are rotatably mounted on the two mounting plates 9 respectively, and the two ends of the static elimination mechanism 8 are fixedly mounted on the top of the two mounting plates 9 respectively.

[0040] The static eliminator mechanism 8 includes a static eliminator 81 and two sets of brackets 82. The two sets of brackets 82 are fixedly installed on the tops of two mounting plates 9, and the static eliminator 81 is fixedly installed between the two sets of brackets 82. The brackets 82 are sheet metal parts formed by stamping and bending, and the sheet metal parts are fixed to the mounting plates 9 by multiple bolts. The static eliminator mechanism 8 designed above has a simple structure and is firmly installed. When the static eliminator 81 is working, it can blow an airflow containing positive and negative ions toward the conveyed film, thereby achieving a good static elimination effect.

[0041] In this embodiment, the film conveying roller group 6 includes an active roller 61, a movable roller 62, and a clamping power member 63. The position of the active roller 61 is not adjustable relative to the mounting plate 9, while the position of the movable roller 62 is horizontally adjustable relative to the mounting plate 9. The clamping power member 63 has two sets, each corresponding to one of the two mounting plates 9.

A base 42 and a hydraulic brake caliper 43 are provided on the frame 1. The hydraulic brake caliper 43 is installed on the base 42 and adapted to the turntable 41. The hydraulic brake caliper 43 is used to prevent the turntable 41 from rotating.

[0045] The beneficial technical effects of the automatic bagging machine for round paper drums according to the embodiments of this application are roughly as follows:

[0046] During the process of the film conveying roller group 6 clamping the film and conveying it downwards, the static elimination mechanism 8 can perform static elimination treatment on the film held by the film conveying roller group 6, thereby minimizing the amount of static electricity carried on the film. As a result, when the film below the film conveying roller group 6 approaches or contacts the round paper drum, the interference of static electricity on the film cutting, film spreading and film welding processes is reduced, and it is less likely to cause jamming or even machine stoppage, which is conducive to efficient operation.
