Self-sealing clamping and conveying device

Abstract

The invention discloses a self-sealing clamping conveying device which comprises a left conveying mechanism and a right conveying mechanism which are symmetrically arranged, each conveying mechanism comprises a driving roller, a driven roller and a conveying belt, the driving roller and the driven roller are arranged front and back, the conveying belt surrounds the driving roller and the driven roller, and an air bag body is arranged on the outer side of the conveying belt. The air bag body is arranged on the conveying belt in a pre-stretching mode. The pre-stretching air bag body is adopted, the air bag body automatically generates sealing faces at the positions of the rollers at the two ends through pre-stretching stress, the self-sealing performance is achieved, and the sealing structure is simplified.

Description

technical field [0001] The invention relates to a clamping and conveying device, in particular to a patent application material for a self-sealing clamping and conveying device. Background technique [0002] For the orderly harvesting of stem and leaf vegetables, flexible clamping conveyor belts are generally used to complete the orderly collection and transportation of vegetables, such as patents CN201621390378.8, CN201910159271.4, CN201821348199.7, CN201910127937.8. The flexible conveyor belts run in the same direction, and the end support rollers and the middle floating rollers are used to make the conveyor belt pre-tension. When the vegetable stems are located between the two flexible conveyor belts, the conveyor belt will be bent and deformed. At this time, the tension of the conveyor belt can be given The stem exerts pressure to create a gripping force. When the size of the vegetable stems changes, or when the clamping and conveying are at different positions, the ben...

AI Technical Summary

Problems solved by technology

And because the stems of stem and leaf vegetables are weak and fragile, when the clamping force is too large, the stems and leaves will be brittle, and if the clamping force is too small, the vegetables will fall off. Therefore, the suitable range of clamping force for each vegetable is different and relatively Small

Therefore, due to the uneven clamping force of the existing clamping and conveying mechanism, it is difficult to adapt to the workplace where the size of the stem changes greatly, resulting in a high damage rate

This structure needs to be adjusted when it is used among different varieties of vegetables, resulting in low versatility

In order to overcome the shortcomings of the existing technology, the patent No. CN202021209453.2 has been developed, and the patent name is the equal contact stress clamping conveying device. The contact stress between the conveying mechanism and the vegetable stems provided by this patent remains basically unchanged to adapt to different vegetables. However, the mechanism has the disadvantages of large gas consumption and complicated structure in practical application.
