Description
Technical Field
[0001] The utility model relates to the technical field of woven bag cutting machines, in particular to a cutting mechanism for producing plastic woven bags. Background Art
[0002] In the production process of plastic woven bags, cutting operations are required. In the prior art, most of them are done by hot cutting. However, this method is prone to the phenomenon that the two sides of the bag mouth are easily stuck together. Therefore, a cutting device is needed to solve this problem.
[0003] For example, the authorization announcement number is "CN218140158U", which is a cutting device for producing plastic woven bags. The cutting device for producing plastic woven bags drives the threaded rod to rotate through a motor, and the threaded connection block drives the flattening roller to move on the plastic woven bag to flatten the plastic woven bag, thereby flattening the plastic woven bag to prevent the plastic woven bag from curling and causing uneven cuts. However, the above-mentioned cutting device for producing plastic woven bags drives the threaded rod to rotate through a motor, so that the threaded connection block moves left and right, and the plastic woven bag is flattened by the flattening roller under the threaded connection block. When the rolling roller flattens the plastic woven bag, static electricity is easily generated due to the influence of friction, which easily causes the right end of the plastic woven bag to be adsorbed to the surface of the flattening roller, causing the plastic woven bag to wrinkle again and the cutting position to shift, thereby affecting the cutting effect. At the same time, the cutting structure in the above-mentioned cutting structure is fixed in position and does not have an adjustment structure, so it is impossible to cut the plastic woven bag at different positions. Therefore, the device has high limitations. Utility Model Content
