A vest bag making machine for plastic packaging with a flattening device and its application method

Abstract

The invention discloses a vest bag making machine for plastic packaging with a flattening device in the technical field of plastic packaging. It includes a bag making machine body and an unwinding roller. Flattening device, the flattening device includes a frame fixedly connected with the outer wall of the top of the bag making machine body, the top of the inner cavity of the frame is provided with a mounting groove, and the top of the cavity of the mounting groove is screwed with a screw, and the bottom of the screw It is rotatably connected with the guide rod, and the bottom end of the guide rod is fixedly connected with the flattening device. The fixed rod is rotated in the device to remove the fixed block from the inner cavity of the fixed groove, and the fixed rod is pushed to the left to make the two groups of flattened blocks move toward each other. Expand the outer side to increase the coverage of the flattening block, ensure that the flattening block is in full contact with the bag-making raw materials, ensure the flattening effect of the flattening block on the bag-making raw materials, and increase the coverage of the flattening block, so that the flattening block can be It is suitable for raw materials with a wider width and increases the use range of the device.

Description

technical field [0001] The invention relates to the technical field of plastic packaging, in particular to a vest bag making machine for plastic packaging with a flattening device and a use method thereof. Background technique [0002] In plastic packaging, plastic packaging bags need to be used. When using a bag making machine to produce vest bags, in order to ensure that the raw materials will not be warped or wrinkled, a flattening device is generally used to flatten the raw materials. However, the existing The flattening plate of the flattening device is generally fixedly installed on the device, resulting in a fixed position of the flattening plate and a fixed size of the flattening plate. If the raw material released by the unwinding roller is not completely under the flattening plate, It will cause the pressing plate to be unable to fully flatten the raw materials, which will affect the quality of the production of vest bags. Therefore, we propose a vest bag making ma...
