Membrane forming mechanism under marinated egg packaging

Abstract

The invention discloses a film forming mechanism under marinated egg packaging, and the film forming mechanism comprises a film rolling switching mechanism, a thermoforming mechanism, a traction mechanism, a connecting mechanism and a controller, wherein the film rolling switching mechanism comprises a first machine shell, an adjustable clamping mechanism, a feeding mechanism and a first infraredsensor; the thermoforming mechanism comprises a workbench, a female die, an upper heating die and a driving mechanism; the traction mechanism comprises a second shell, a guide roller, a driving rollerand a first driving motor; the connecting mechanism comprises a fixed frame, a transverse moving lifting mechanism, a linking mechanism, a supporting mechanism and a heating strip; and the controlleris electrically connected with the film rolling switching mechanism, the thermoforming mechanism, the traction mechanism and the connecting mechanism. According to the invention, after a roll film iscompletely unreeled, a new roll film can be automatically switched through the film rolling switching mechanism, the head end and the tail end of the new roll film and the old film are connected through the connecting mechanism, so that the function of quickly replacing the roll film is realized, the formed lower film is obtained through the thermoforming mechanism, a movable female die is separated from a fixed female die after forming, and the formed lower film is convenient to be separated from the female die.

Description

technical field [0001] The invention relates to the technical field of marinated egg packaging equipment, in particular to a lower film forming mechanism for marinated egg packaging. Background technique [0002] In the packaging of marinated eggs, usually a plurality of egg troughs for placing marinated eggs are pressed on a lower plastic film, then covered with an upper plastic film, and then heated and sealed. The existing lower film forming equipment has the following disadvantages: [0003] 1. The roll film cannot be switched automatically. After unwinding a roll film, it needs to stop, and the worker unloads the inner tube of the empty roll, and then reinstalls the new roll film. Hidden dangers, low degree of automation, not suitable for modern production; [0004] 2. Since the concave mold has grooves, it is not easy to separate from the concave mold after the lower film is formed, and the formed lower film is easily damaged by contact friction with the concave mold...

AI Technical Summary

Problems solved by technology

[0003] 1. The roll film cannot be switched automatically. After unwinding a roll film, it needs to stop, and the worker unloads the inner tube of the empty roll, and then reinstalls the new roll film. This process is time-consuming and laborious, and there is a safety hazard Hidden dangers, low degree of automation, not suitable for modern production;

[0004] 2. Since the concave mold has grooves, it is not easy to separate from the concave mold after the lower film is formed, and the formed lower film is easily damaged by contact friction with the concave mold;

[0005] 3. It does not have the function of automatic deviation correction, which causes the roll film to deviate during the feeding process, and it is easy to produce defective products during forming
