Bag opening mechanism

Abstract

The invention discloses a bag opening mechanism which comprises a movable arm, a cam, a first pulley wheel, a second pulley wheel, an upper adsorbent and a ratchet mechanism, wherein one end of the movable arm is hinged, the first pulley wheel and the second pulley wheel are connected and are both arranged on the movable arm, the first pulley wheel is fixedly connected with one end of a swing rod,the other end of the swing rod is in contact with the cam, the swing rod is provided with a spring which always applies a force to the direction of the cam to the swing rod, the first pulley wheel rotates along with the swing rod, and the second pulley wheel rotates along with the first pulley wheel; the cam can rotate for a circle when the movable arm is lifted once; the second pulley wheel is connected with the upper adsorbent through a lifting connecting rod which is vertically arranged, and the upper adsorbent is connected with the movable arm through a distance regulating mechanism and is used for adsorbing a bag below the adsorbent; a transport mechanism used for transporting the bag is arranged below the upper adsorbent, and a lower adsorbent corresponding to the position of upperadsorbent is arranged below the transport mechanism. The opening of the bag can be realized only through the mechanical structure, so that the bagging efficiency is improved.

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, diseases and insect pests, and damage from wind, rain and sunlight during the growth process. Will not be scratched by branches. Bagging can produce a local greenhouse effect, keep the fruit at 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, because no pesticides are needed during the growth process, the fruits are of high quality and pollution-free, reaching international standards. [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 veg...

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
