Hydraulic transmission open bag sealing device based on hydraulic valve control

Abstract

The invention relates to the technical field of hydraulic transmission, and discloses a hydraulic transmission open bag sealing device based on hydraulic valve control. The hydraulic transmission openbag sealing device comprises a motor, and one end of the motor is movably connected with an oil pump. One end of an oil outlet pipeline is movably connected with an overflow valve, and the bottom endof a movable rod is movably connected with a fixed strip. The surface of a fixed plate is fixedly connected with a fixed ring, and an auxiliary long rod is movably connected in the fixed ring. The bottom end of the auxiliary long rod is movably connected with the lower side of a sealing device body. According to the hydraulic transmission open bag sealing device based on hydraulic valve control,by means of connection of the motor and an electromagnet, the problem that according to an existing heat sealing type sealing machine, mainly manual pressurization is adopted after heating is carriedout, and consequently the labor intensity is large is solved; by means of connection of a movable piston and the lower side of the sealing device body, the problem that gear transmission is adopted bypart of mechanical type sealing machines, and consequently the structure is complex is solved, the problem of expensive machining is solved, cost is reduced, and the practicality is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic transmission, in particular to a hydraulic transmission bag opening and sealing device based on hydraulic valve control. Background technique [0002] With the development of my country's economy, my country's food processing has also entered the road of rapid development. An important part of food processing is the preservation and sealing of food. Among them, the heat-sealing sealing machine is a common sealing machine. The device heats the material at the sealing point to make it reach a viscous flow state, and then pressurizes it to seal it, so that the food in the food bag can be preserved. [0003] The existing heat-sealing sealing machine is mainly manually pressurized after heating, which has high labor intensity, high labor cost, low automation level, and low production efficiency. In addition, the mechanical sealing machine adopts gear transmission, which is not only complicated in stru...
