Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag edge sealing, in particular to edge sealing equipment for packaging bag processing. Background Art

[0002] In the process of packaging bag processing, edge sealing of packaging bag is an important process in packaging bag processing. It is necessary to use the heat sealing knife on the edge sealing equipment to heat seal the edge of the packaging bag, so as to facilitate the use of the packaging bag.

[0003] The existing announcement number is CN210792233U, which is a packaging bag edge sealing device. This patent uses a heating plate to heat it, so that the glue dries quickly and strengthens the adhesion. Since the folding plate only exposes the pasting position of the packaging bag and the other positions are pressed by the folding plate, the pressing plate will not squeeze the glue into the packaging bag, so that the glue is evenly distributed on the edge of the packaging bag.

[0004] The inventor found in his daily work that the above-mentioned packaging bag edge sealing equipment has a relatively simple packaging bag positioning method, which is to press the packaging bag by the transmission roller, and the transmission roller is still in an active state, resulting in the packaging bag being easily displaced or warped during the edge sealing process, thereby affecting the subsequent edge sealing quality. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problems in the above background and to provide edge sealing equipment for packaging bag processing.

The clamping plate has the effect of clamping and fixing the packaging bag.

[0009] Preferably, a reinforcing device is provided on the surface of the base, and the reinforcing device includes an L-shaped rod, and the L-shaped rod is fixedly mounted on the surface of the base, and a negative pressure cylinder is fixedly mounted on the surface of one end of the L-shaped rod away from the base, and a connecting pipe is fixedly mounted on the surface of one end of the negative pressure cylinder, and the end of the connecting pipe away from the negative pressure cylinder is connected to the hollow plate, and a plurality of through holes are evenly opened on the surface of the hollow plate. The setting of the L-shaped rod plays the effect of supporting the negative pressure cylinder.

The arrangement of the slide and the round rod has the effect of driving the piston plate to move inside the negative pressure cylinder.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, by setting a pressing device, when it is necessary to seal the edge of the packaging bag, first the packaging bag is placed on the surface of the hollow plate, and then the rotating wheel is rotated. The rotation of the rotating wheel drives the threaded rod to rotate. Since the threads on the surface of the threaded rod are mutually reverse threads with the rotating wheel as the center, when the rotating wheel drives the threaded rod to rotate, the two movable plates threadedly connected on its surface will move in the direction away from each other inside the groove. The two movable plates move in the direction away from each other inside the groove, driving the hinge plate to move. The hinge plate moves and pulls the T-shaped pressing plate to move downward. The T-shaped pressing plate moves downward to press and fix the packaging bag on the surface of the hollow plate. When the packaging bag is pressed and fixed, the cylinder is started. The cylinder starts and drives the heat sealing knife to move downward. When the heat sealing knife moves downward and fits tightly with the packaging bag, the heat sealing knife is used to seal the packaging bag. Through the cooperation of the above structure, the purpose of pressing and fixing the packaging bag is achieved, and the position displacement and warping of the packaging bag are avoided, thereby ensuring the edge sealing quality of the packaging bag.

[0014] 2. In the utility model, by setting a reinforcing device, when it is necessary to strengthen the limiting of the packaging bag, first start the electric telescopic rod, the electric telescopic rod starts to drive the slide plate to move inside the vertical groove, the slide plate moves inside the vertical groove and drives the round rod to move, the round rod moves and pulls the piston plate to move, the piston plate moves to form a negative pressure in the gas inside the negative pressure cylinder, and then the bottom end of the packaging bag is positioned by adsorption through the connecting pipe. Through the cooperation of the above structure, the limiting effect of the packaging bag is further strengthened, so that the position of the packaging bag is more stable when the device is sealing the edge.
