Container sealing and packaging machine

Abstract

The invention discloses a container sealing and packaging machine which comprises a machine shell. A machine cover is hinged to the upper portion of the machine shell, a thin film is arranged in the machine shell, a container is arranged in the machine shell in a drawing mode, two sets of installation supports are symmetrically installed in the machine shell, and fixing supports are installed below the two sets of installation supports. The two sets of fixing supports are fixedly connected and form a fixed driving hand section, a power device is arranged in the fixed driving hand section, anda lifting starting hand section is guided by lifting rods to ascend and descend through the driving force of the power device. The lifting starting hand section is composed of the following structuresincluding the multiple lifting rods which are slidably combined on the installation supports of the fixed driving hand section in the vertical direction. As convex parts are respectively formed on the upper side and the lower side, guide rails combined with the side surface of a spherical tray can be inserted into roller grooves formed in the inner side surfaces of the installation supports of the fixed driving hand section, shaking can be prevented when the spherical tray moves forwards and backwards, and poor sealing and packaging phenomena can be prevented when a fed container is arrangedmistakenly.

Description

technical field [0001] The invention relates to the technical field of packaging machines, in particular to a sealing packaging machine for containers. Background technique [0002] Generally, when storing vegetables, fruits, fruits, etc. classified as natural foods, and general restaurant delivery foods, etc., they are mainly put into food containers and then sealed in a food packaging machine. However, in the usual airtight packaging machine for food containers, after placing the food container with food on the container backing plate provided at the lower part of the main body, the container inlet and the container backing plate enter the main body through the motor, and at the same time, the film at the end, the tray Enter after aligning with the film clip. Then, as the cam motor drives, the first cam provided on the shaft will rotate, and since the second cam in contact with the first cam is fixed in the heater plate, the heater plate will finally move to the lower par...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a sealing packaging machine for containers, which solves the problem that if the first cam and the second cam are arranged in the center, the pressure of the heater plate will be biased towards the center, and the corners of the food container will not achieve the sealing effect. The defect rate is high, and it is difficult to make the cam device accurately at the center during the main body production process, and when the food container is small or large, the sealing state is very bad due to the heavy pressure, so it has the disadvantages The problem of rising defective rate, this technical problem
