Bag taking and mouth prop-open device and method suitable for single layer or multilayer paper fruit bagging

Abstract

The invention discloses a bag taking and mouth prop-open device and method suitable for single layer or multilayer paper fruit bagging. The device comprises a device bracket, a bag supplying mechanism, a bag taking and mouth prop-open hand claw and a hand claw driving mechanism, the hand claw driving mechanism and the bag supplying mechanism are respectively arranged on the device bracket, and thebag taking and mouth prop-open hand claw is arranged on the hand claw driving mechanism; the bag taking and mouth prop-open hand claw is arranged above the bag supplying mechanism, in the bag takingand mouth prop-open hand claw, a guiding rod passes through the center of an upper slide bushing and the center of a lower slide bushing, and the upper end of the guiding rod is fixed to the hand clawdriving mechanism; a limit stop block is fixedly connected with the lower end of the guiding rod, and three finger supporting components are symmetrically distributed around a center shaft of the guiding rod. The method comprises the steps that the bag supplying mechanism supplies fruit bags, the hand clamp driving mechanism drives the bag taking and mouth prop-open hand claw to keep a closed state and reach inside a fruit bag, and then the fruit bag is taken out, and the bag taking and mouth prop-open hand claw stretches to prop open the fruit bag mouth. According to the bag taking and mouthprop-open device and method, the action is simple in the bag taking and mouth prop-open process, the efficiency is high, the control is easy, the cost is low, and the device and method are better applicable to the agriculture requirements for the multilayer paper fruit bagging.

Description

technical field [0001] The invention relates to the technical field of fruit bagging, in particular to a device and method for taking out bags and supporting mouths suitable for single-layer or multi-layer paper fruit bagging. Background technique [0002] Fruit bagging technology helps to improve the appearance quality of fruits, block pesticide and dust pollution, prevent pest damage and sunburn, and reduce mechanical damage caused by typhoons and hailstorms. However, at present, the fruit bagging operation still relies on manual operation, which has problems such as cumbersome operations, low efficiency, and high labor intensity for fruit farmers. The development of bagging operation equipment has important practical significance for promoting the promotion and application of fruit bagging technology in my country. Young fruit bags are made of non-woven fabrics, plastic films, and paper bags. Paper bagging is environmentally friendly and biodegradable, especially multi-l...

Problems solved by technology

[0005] However, each of the above-mentioned public documents is to improve the structure of ordinary paper bagging, which will not only increase the production cost of bagging, but also adopt the method of taking out the bagging and then opening the mouth of the bag, which takes a long time.

Ordinary multi-layer paper bagging is generally formed by bonding. It is bonded from two sides or one side longitudinal seam, a low seam, and a local point on the top. Opening method, it is difficult to ensure that the inner bag and the outer bag are opened consistently. After bagging, the inner fruit bag is easy to contact with the surface of the fruit, which may easily cause burns on the surface of the fruit.
