Description

Technical Field

[0001] The utility model relates to the technical field of film bag making machines, in particular to a film bag making machine. Background Art

[0002] Bag making machine is a machine for making various plastic packaging bags or other material packaging bags. Its processing range is packaging bags of various sizes, thicknesses and specifications of plastics or other materials. Generally speaking, plastic packaging bags are the main products.

[0003] In the manufacture of many films, it is necessary to trim the films according to customized requirements. The cutting equipment is used to cut off a part of the structure at the edge of the film so that the entire film bag presents a different shape. When the end of the cutting equipment descends and prepares to trim the film, since the film has no restrictions at this position, it is easy to warp, etc., resulting in deviations in the cutting position. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a film bag making machine to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: comprising: a bag making machine body, a guide frame plate fixed on the upper end of the bag making machine body, and a film body inserted between the guide frames.

[0008] The cutting part is installed at the bottom of the pressing column;

[0009] The clamping plate is arranged on one side of the cutting part, a pressing support rod is fixed on the top of the clamping plate, the top of the pressing support rod is connected to the outer wall of the pressing sleeve ring, the clamping plate is U-shaped, and the U-shaped opening of the clamping plate faces one side of the cutting part.

[0010] Furthermore, a collar limiting groove is provided on the outer wall of the pressing column, and a sliding block which slides along the collar limiting groove is fixed on the inner wall of the pressing collar.

[0011] Furthermore, a positioning slot is provided at the bottom of the pressing column, a cutting portion is inserted into the slot of the positioning slot, and a locking screw is passed through the side wall of the pressing column.

[0012] Furthermore, an electric push rod is fixedly provided on the side wall of the bag making machine body, and the output end of the electric push rod is connected with a downward pressing connecting plate.

[0013] Furthermore, a positive and negative threaded rod is horizontally mounted above the bag making machine body, and one end of the positive and negative threaded rod is connected with a downward pressing connecting plate.

[0014] Furthermore, a telescopic plate is installed on the side wall of the bag making machine body and located opposite to the lower pressing connecting plate. The other end of the positive and negative threaded rods is rotatably connected to the telescopic plate, and a guide rod is fixed between the telescopic plate and the lower pressing connecting plate.

[0015] Furthermore, the outer engagement sleeve of the positive and negative threaded screw is provided with a screw engagement sleeve, the lower half of the screw engagement sleeve is slidingly sleeved outside the guide rod, and the top of the downward pressing column is fixed to the bottom wall of the screw engagement sleeve.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] When the cutting part of the present application descends to perform the edge trimming action on the film body, the clamping plate can fall due to its own weight, so that the clamping plate first contacts the surface of the film body, thereby limiting the position of the film body and keeping the film body in a relatively stable state. In this way, the subsequent cutting can be in a relatively accurate state, thereby improving the quality of edge trimming. The cutting part adopts a quick-release design, and the spacing between the oppositely distributed cutting parts can be adjusted. The position and shape of the cutting can be adjusted according to needs, and the scope of application is wider. BRIEF DESCRIPTION OF THE DRAWINGS
