Description

PE bag production raw materials unreeling device Technical Field The utility model belongs to the technical field of packaging consumable equipment, and particularly relates to a PE bag production raw material unreeling device. Background The PE antistatic packaging bag is a special packaging bag, and is formed by mixing and blowing films of low-density polyethylene (LDPE) +linear low-density polyethylene (LLDPE) +antistatic master batch+color master batch+stabilizer, and then heat-sealing and cutting. The material has soft hand feeling and thickness which can be freely adjusted according to the requirement. The PE antistatic packaging bag has an antistatic function, can effectively prevent static charge accumulation, and protects electronic products from electrostatic damage to electronic components due to mutual friction between insulators. The surface resistivity is low, which is also an important expression of the antistatic property. When the PE antistatic packaging bag is produced, the packaging bag roll is required to be wound and carried for the convenience of subsequent production of packaging bags with corresponding shapes, and then the packaging bag roll is cut into different lengths again by using an unreeling device according to the requirements. The chinese patent literature of application number CN202420174887.5PE discloses a raw materials unreeling device for flat pocket production, comprising a base plate, the bottom plate top surface is provided with two backup pads, two backup pad bottom surfaces and bottom plate top surface fixed connection, two backup pad top surfaces are provided with two line rollers, management line roller bottom surface and two backup pad top surface fixed connection, two backup pad top surfaces are provided with stop gear and pushing down the mechanism, stop gear includes fixed part and spacing portion, spacing portion is located fixed part medial surface, pushing down the mechanism and including pushing down portion and drive division, drive division is located pushing down the portion top surface. Along with the further research of applicant, it is found that because the technical scheme is limited by the structure of the PE bag, offset easily occurs in the unreeling and conveying process of the PE bag, so that uneven and offset occurs when the PE bag is cut, the packaging quality of the PE bag is affected, and the working efficiency is reduced. Disclosure of utility model In order to solve the technical problems, the utility model adopts the following technical scheme: a PE bag manufacturing raw material unreeling device, comprising: the tail part of the frame body is provided with a placing frame; a plurality of bag feeding rotary rollers are sequentially arranged on the frame body along the bag discharging conveying direction; The cutting assembly is arranged at the head of the frame body and used for cutting the bag body; The limit stop is arranged on the feeding side of the blanking assembly and is symmetrically connected with two sides of the frame body; an upper rotating roller and a lower rotating roller are arranged between the bag feeding rotating roller and the blanking component in pairs; And the adjusting structure is used for moving at least one of the upper rotating roller and/or the lower rotating roller so as to enable the upper rotating roller and the lower rotating roller to be close to or far away from each other. Further, the adjusting structure comprises a rotating part and installation side plates symmetrically connected to two sides of the frame body and connected with the upper rotating roller and the lower rotating roller in a rotating mode, sliding blocks are sleeved at two ends of the upper rotating roller, sliding grooves matched with the sliding blocks are formed in the installation side plates, and the rotating part penetrates through the top of the installation side plates and is connected with the sliding blocks. Further, the blanking assembly comprises a tool rest and a lower bottom plate which are connected with the inner wall of the installation side plate in a sliding mode, and a tool body which is matched with the lower bottom plate and acts on the bag body is installed on the tool rest. Further, the blank subassembly still includes the roof that is connected with the installation curb plate, the roof upper end is connected with the extensible member, extensible member free end runs through the top and is connected with the knife rest. Further, be provided with on the knife rest with lower plate matched with holding down plate, the holding down plate upper end is provided with a plurality of guide bars that run through the knife rest along length direction, the guide bar periphery cover is equipped with the spring.
