A bag opening mechanism

Abstract

The invention discloses a bag opening mechanism, which comprises a movable arm, a cam, a first pulley, a second pulley, an upper adsorption body and a ratchet mechanism; One end of the swing rod is fixedly connected to the first pulley, and the other end of the swing rod is in contact with the cam. The swing rod is provided with a spring, and the spring always gives the swing rod a force towards the cam. The first pulley rotates with the swing rod, and the second pulley follows The first pulley rotates; the movable arm is raised once, and the cam rotates once; the second pulley is connected to the upper adsorption body through a vertically arranged lifting link, and the upper adsorption body is connected to the movable arm through a distance adjustment mechanism; the upper adsorption body is used for Adsorbing the bag below it; a transmission mechanism for transporting bags is arranged under the upper adsorption body, and a lower adsorption body corresponding to the position of the upper adsorption body is arranged under the transmission mechanism. Only the mechanical structure can realize the opening of the bag and improve the efficiency of bagging.

Description

Technical field[0001]The invention belongs to the field of fruit bagging and relates to a bag opening mechanism.Background technique[0002]Fruit bagging is mainly to prevent the fruit from being attacked by birds, pests and diseases, and damage from wind, rain and sun during the growth process. At the same time, after the fruit is bagged, it can effectively isolate the erosion of the fruit from environmental pollution and prevent the fruit during the growth process. Will not be scratched by branches. Bagging can produce a local greenhouse effect, keep the fruit at the proper humidity and temperature, increase the sweetness of the fruit, improve the luster of the fruit, increase the yield of the fruit, and shorten its growth period. At the same time, since there is no need to apply pesticides during the growth process, the fruits are of high quality and pollution-free, reaching international standards.[0003]The existing fruit baggings are mainly plastic bags. Because plastic bags have...

AI Technical Summary

Problems solved by technology

[0003] Existing fruit bagging is mainly plastic bags, because plastic bags have poor air permeability, high light transmittance, soft texture, and are easy to attach to the surface of fruits, so the growth protection effect on fruits and vegetables is poor, and the produced Both the gloss and color of vegetables and fruits cannot meet the ideal standard

Although paper fruit bagging has good protection performance, light transmission and air permeability can meet the production requirements of fruit, but at present paper bagging can only be bagged by hand, the bagging efficiency is low, and it is difficult to unify Therefore, it is urgent to design a mechanical bag opening mechanism to facilitate fruit bagging
