Damping vacuum packing machine

Abstract

The invention relates to a packing machine, in particular to a damping vacuum packing machine, which comprises a machine cover, a vacuum chamber and an uncapping control mechanism; the damping vacuum packing machine is characterized in that the uncapping control mechanism comprises a tension spring, a swing arm, a tension spring connecting seat, roller wheels, an upper damping block and a lower damping block; two ends of the rear side of the machine cover are respectively connected with the upper end of the swing arm; the lower end of the swing arm is rotatably connected with one end of the tension spring connecting seat; the other end of the tension spring connecting seat is connected with one end of the tension spring of which the other end is connected to the outside part of the vacuum chamber; the roller wheels are arranged on the tension spring connecting seat; the upper and lower damping blocks are arranged outside the vacuum chamber to form a horn-shaped channel; the setting position of the horn-shaped channel is consistent with the moving direction of the roller wheels. The invention aims to design the damping vacuum packing machine which is soft in uncapping and small in inertia. Compared with the prior art, the damping vacuum packing machine has the advantages of adjustable uncapping height and speed, slow uncapping stopping speed, small uncapping vibration and the like.

Description

technical field [0001] The invention relates to a vacuum packaging machine, in particular to a damping type vacuum packaging machine. Background technique [0002] The vacuum packaging machine is a device that can automatically extract the air in the packaging bag and complete the sealing process after reaching a predetermined vacuum degree. At present, the mechanisms used in the lid opening control mechanism of vacuum packaging machines include air support mechanisms, spring mechanisms and tension spring mechanisms. The service life of the air support mechanism is not long. After a period of use, there will be oil leakage and air leakage, resulting in pressure failure; the spring mechanism cannot effectively control the spring buffer. When the spring springs up, the inertia is large, which is easy to damage the machine cover and accidental injury Operator: The tension spring mechanism also has a large inertia phenomenon, which cannot effectively control the tension and buf...

The service life of the air support mechanism is not long. After a period of use, there will be oil leakage and air leakage, resulting in pressure failure; the spring mechanism cannot effectively control the spring buffer. When the spring springs up, the inertia is large, which is easy to damage the cover and accidental injury Operator: The tension spring mechanism also has a large inertia phenomenon, which cannot effectively control the tension and buffering of the tension spring. After a period of use, the tension spring becomes weak, the tension is not enough, or the cover is not opened properly, and the cover shakes up and down
