Problems solved by technology

[0006] In the production process, the plastic film made into a roll is very light and thin, and the static electricity is extremely high. The plastic film needs to be flattened before cutting, otherwise the static electricity is very large, and it is not easy to keep the plastic film flat, which will affect the quality of the finished product.

Embodiment Construction

[0022] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0023] Such as figure 1 As shown, this embodiment includes the following steps:

[0024] (1) Winding the blow-molded plastic film 1 on the discharge roller, pressing the plastic film 1 on the discharge roller, and discharging it after being leveled by the first material roller;

[0025] (2) Remove static electricity to plastic film 1, prevent plastic film 1 from swinging when removing static electricity, carry out edge sealing after removing static electricity, the plastic film 1 after edge sealing is a plurality of continuous plastic bags; If color printing is required, after edge sealing The plastic film 1 is p...

Abstract

The invention discloses a flattening device used for plastic bag production. The flattening device comprises supports, a connecting rod and two flattening bags. The supports are fixed at two ends of the connecting rod. The flattening bags hang on the connecting rod and are made of cotton. One side of each flattening bag is laid on a bench, and other side of each flattening bag is provided with a ballasting pocket used for accommodating a flexible weight. The flattening device is easy to use, smoothing and antistatic processing are performed on plastic films before cutting, disorderliness never occurs, and continuous production of the whole production line is smooth and ordered.

Description

technical field [0001] The invention relates to a plastic bag making equipment, in particular to a flattening device in the plastic bag production process. Background technique [0002] Plastic bags are common products in daily life, and their production process is generally as follows: The first step is film blowing, which is a plastic processing method that refers to a plastic processing technology that heats and melts plastic particles and then blows them into films. The first step in making plastic bags. [0003] If it is a film blown out of new particles, the color is bright, clean and hygienic, the finished product stretches well, bears a large weight, and the quality of the plastic bag is good, so it can be used for food packaging. If the plastic granules made of recycled waste plastics are usually added with color masterbatch to the raw material granules when blowing the film, the resulting film is prone to uneven coloring, brittle and easy to break, and the resulti...
