Description

Technical Field

[0001] The utility model belongs to the technical field of flattening devices, in particular to a flattening device for producing plastic bags. Background Art

[0002] Plastic bags are bags made of plastic as the main raw material. Commonly used plastics include polypropylene, polyester, nylon, etc. Plastic bags are lightweight, durable, waterproof, moisture-proof, and have large capacity and are easy to store. They are indispensable items in people's daily lives and are widely used to package food and goods, as well as as garbage bags, transport bags, etc. However, the use of plastic bags also brings environmental problems. Therefore, some areas have begun to restrict the use of non-degradable plastic bags and promote the use of environmentally friendly bags. In the production process of plastic bags, the air in them needs to be squeezed out, and a flattening device is required. The existing patent (Announcement No.: CN219727416U) discloses a flattening device for plastic bag production.

[0019] When in use, the operator starts the first motor 3 to drive the first gear 5 to rotate. When the first gear 5 rotates, the second gear 6 rotates along the first shaft seat 4. When the second gear 6 and the first gear 5 rotate, the shaft rod 7 is driven to rotate along the inside of the shaft sleeve 8. When the two shaft rods 7 rotate, the two squeezing rollers 9 are driven to rotate by the cooperation of the first clamping block 12 and the first clamping groove 10, so that the plastic bag can be flattened. When disassembling, the operator starts the quick disassembly assembly to run forward. When the quick disassembly assembly runs forward, the internal limit of the two second clamping grooves 11 is withdrawn from the quick disassembly assembly to quickly complete the disassembly. When installing, the operator puts the two first clamping grooves 10 on the two squeezing rollers 9 onto the two first clamping blocks 12, and then starts the quick disassembly assembly to run in reverse. When the quick disassembly assembly runs in reverse, it is clamped into the internal of the two second clamping grooves 11 for limit, so as to quickly complete the installation.
