Problems solved by technology

[0004] However, in its technical solution, it is only used to realize a simple flattening action, and at least five motors such as two push rod motors, a first drive motor, a second drive motor, and a third drive motor are arranged, which have the following disadvantages: (1 ) The installation and debugging operation is complicated; (2) There are many motors and the cost is high. Although the flattening action can be realized, the power consumption and cost are too high. In short, the use cost of the above patent is too high, which is not conducive to enterprise use

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 1~4 , in an embodiment of the present invention, a plastic bag flattening mechanism combined with a smoothing roller and hot air, including a frame 1, a smoothing mechanism 2, a fan 5, an electric heating roller 9 and a tensioning mechanism, the two parts of the frame 1 Both sides are fixed with side plates 17, and the frame 1 and side plates 17 form a channel for semi-finished plastic bags 15 to pass through. In this channel, a smoothing me...

Abstract

The invention discloses a plastic bag flattening mechanism characterized by combination of trowelling rollers and hot air. The plastic bag flattening mechanism comprises a machine frame, a trowellingmechanism, a fan, an electric heating roller and a tensioning mechanism. Side plates are fixedly arranged on the two sides of the machine frame, the machine frame and the side plates are combined in an encircling mode to form a channel which allows a semi-finished plastic bag to pass through, and the trowelling mechanism and the tensioning mechanism are installed in the channel. The trowelling mechanism comprises the first trowelling roller and the second trowelling roller, wherein the first trowelling roller and the second trowelling roller are opposite in position and are driven by an external power mechanism to rotate in an opposite mode. The plastic bag flattening mechanism has the beneficial effects that folds on the surface of the semi-finished plastic bag can be stretched towards the two sides by inclined lines which are outwards diffused, and therefore the surface of the semi-finished plastic bag can be flat; then the semi-finished plastic bag is heated and cooled, and therefore the shape of the plastic bag is fixed; and the flattening quality of the plastic bag can be greatly improved, and the later-period processing of the plastic bag is facilitated.

Description

technical field [0001] The invention relates to the technical field of plastic bag processing, in particular to a plastic bag flattening mechanism combined with a smoothing roller and hot air. Background technique [0002] During the processing of plastic bags, it is usually necessary to level the semi-finished plastic bags to facilitate subsequent plastic bag processing and molding operations. The traditional method is to use manual leveling. This method is very inefficient and consumes a lot of human resources. Moreover, because people have to contact with plastic products during processing, it has an impact on the processor and is not environmentally friendly. Simultaneously, the existing equipment specially used for plastic bag leveling has a high manufacturing cost, which is unfavorable for small enterprises to use. [0003] For this reason, CN206551572U discloses a kind of flattening equipment for producing plastic bags, the distance between the first leveling column,...
