Bag opening mechanism and assembly for fruit net bags

Abstract

The invention relates to a bag opening mechanism for fruit net bags. The bag opening mechanism comprises a base, a push rod, at least two guide plates and at least two bag opening claws, wherein the guide plates and the bag opening claws are in one-to-one correspondence; and the guide plates are mounted at the lower part of the base, the lower end of the push rod penetrates through the base, the bag opening claws are hinged to the lower end of the push rod through connecting rods, and the upper ends of the bag opening claws are in sliding connection with the guide plates. The invention furtherrelates to a bag opening assembly adopting the bag opening mechanism for the fruit net bags. The bag opening assembly further comprises a driving mechanism, wherein the driving mechanism drives the push rod to move upwards and downwards. The bag opening mechanism has the beneficial effects that automatic bag opening can be realized, the bag opening claws slide along the guide plates, and the bagopening claws are driven to open and close.

Description

technical field [0001] The invention relates to a bag supporting mechanism and its components, in particular to a fruit mesh bag supporting mechanism and its components, belonging to the field of fruit packaging machinery. Background technique [0002] In order to prevent the fruit from bumping during transportation, the fruit is protected by a foam net bag. The traditional fruit net bag packaging (such as apples, pears, pomegranates, etc.) is mostly packaged manually, and the packaging efficiency is extremely low. The fruit mesh bag has a mesh structure, has a certain degree of elasticity, is made of air bubbles, and has a certain friction force on the surface, and when the friction is too large, the air bubbles will be damaged, and even the mesh bag will be broken. [0003] In the prior art, fruit net bag packaging machines are continuously released, but these machines are generally complex in structure, or cannot be automated, and still need manual bag support.

AI Technical Summary

Problems solved by technology

[0007] It is easy to think of using an umbrella-like opening mode to open the net bag. Although it is easy to open the net bag in this way, because the movement process is oscillating and the contraction state is conical, there are still mesh bags. It is not easy to fit on the fruit, and the mesh bag is easy to slip forward due to the forward partial thrust during the stretching process. Once the stretching device is stretched into an inverted cone shape, the mesh bag will be difficult to contact with the manipulator. disengage
