[0002] A plastic bag is a bag made of plastic as the main raw material. Common plastics include polypropylene, polyethylene, polyester and nylon.
[0003] In the prior art, during the processing of plastic bags, it is often necessary to press the zipper head and the plastic bag to ensure the firmness and sealing of the zipper. This is usually done by an ultrasonic press, which detects the position of the zipper end of the plastic bag by ultrasonic wave. The heat generated by the ultrasonic press is discharged through a heat dissipation window fixed by surface bolts.
[0004] However, the heat dissipation window of the conventional ultrasonic press is fixed by bolts. When the heat dissipation window is disassembled to inspect the ultrasonic press, tools are needed, which is not convenient. Utility Model Content
[0005] The utility model aims to provide a zipper end pressing device for plastic bag processing to solve the problems raised in the above background technology.
[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a plastic bag processing zipper end pressing device, the plastic bag processing zipper end pressing device comprises:
[0007] The ultrasonic presser body; a transmission groove is provided on the surface of the ultrasonic presser body, a through hole is provided on the bottom surface of the transmission groove, a connecting groove is provided on the bottom surface of the through hole, a first spherical groove is provided on the arc surface of the inner wall of the transmission groove, a heat dissipation window is provided on the inner wall of the ultrasonic presser body, and a second spherical groove is provided on the arc surface of the heat dissipation window;
[0008] The limit rod has a groove on its arc surface, a guide rod is fixed on its bottom surface, a baffle is fixed on its bottom surface, and a spring is sleeved on its arc surface.
[0009] Preferably, the transmission groove is provided with an annular groove near the port position, a through groove is provided on the surface of the annular groove, a limiting ball is provided on the inner wall of the first spherical groove, a limiting block is fixed on the arc surface near the end position of the limiting rod, a fixing block is fixed on the end surface of the limiting rod, the ultrasonic press body is fixed on the surface of the plastic bag production mechanism, and a cylinder is fixed on the surface of the plastic bag production mechanism.
[0010] Preferably, the size of the first spherical groove is larger than that of the second spherical groove, the size of the second spherical groove is the same as the size of the limiting ball, and the notches at both ends of the first spherical groove are smaller than the diameter of the limiting ball. The inner wall of the first spherical groove has a certain slope, and under the action of gravity, the limiting ball will move into the first spherical groove.
[0011] Preferably, two groups of second spherical grooves are provided, and the two groups of second spherical grooves are symmetrically distributed on the arc surface of the heat dissipation window. Two groups of limiting balls are provided, and the two groups of limiting balls are symmetrically distributed on the inner wall of the first spherical groove, and the limiting balls correspond to the second spherical grooves, and the limiting balls are clamped in the second spherical grooves.
[0012] Preferably, the limit blocks are provided in multiple groups, and the multiple groups of limit blocks are distributed in a circle on the arc surface of the limit rod. Multiple groups of annular grooves are opened, and the multiple groups of annular grooves are symmetrically distributed inside the main body of the ultrasonic press, and the limit blocks correspond to the annular grooves, and the limit blocks are clamped in the annular grooves, and the two are movably connected.
[0013] Preferably, the through grooves are provided in a plurality of groups, and the plurality of through grooves are circumferentially distributed on the surface of the annular groove, and the limit blocks correspond to the through grooves, and the limit blocks are clamped in the through grooves, and the two are movably connected.
[0014] Preferably, the size of the through hole is the same as that of the guide rod, the size of the guide rod is smaller than the size of the baffle, and the guide rod is clamped in the through hole, and the spring is located in the transmission groove.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] When the heat dissipation window needs to be removed, the limit rod is driven to rotate by the fixed block. When the limit block corresponds to the through groove, the limit rod is stopped from rotating. Due to the elasticity of the spring, the spring will push the limit rod to move. Since the groove has a certain slope and the first spherical groove has a certain slope, the limit ball will be disengaged from the second spherical groove when the limit rod moves. When the spring is fully extended, the limit ball is completely disengaged from the second spherical groove. At this time, the limit between the heat dissipation window and the ultrasonic press body disappears, and the heat dissipation window can be taken out of the ultrasonic press body. In the same way, the limit ball can be clamped in the second spherical groove by pressing the limit rod, and then the limit rod can be rotated so that the limit block is no longer corresponding to the through groove. This structure is simple and easy to operate, which realizes convenient disassembly and assembly of the heat dissipation window, and is beneficial to improving its use effect.
