Abstract
The invention discloses a self-sealing clamping conveying device which comprises a left group of conveying mechanisms and a right group of conveying mechanisms which are symmetrically arranged, wherein each group of conveying mechanisms comprises a pair of driving rollers and driven rollers which are arranged front and back, and a conveying belt which surrounds the driving rollers and the driven rollers, wherein an air bag body is arranged on the outer side of the conveying belt, and the air bag body is arranged on the conveying belt in a pre-stretching mode. The invention adopts the pre-stretching air bag body, and the pre-stretching stress is utilized to enable the air bag body to automatically generate sealing surfaces at the rollers at the two ends to form self-sealing performance, thereby simplifying the sealing structure.
Description
Technical Field
The invention relates to a clamping and conveying device, in particular to a self-sealing clamping and conveying device patent application material.
Background
The orderly harvesting of stem and leaf vegetables generally adopts flexible clamping conveyor belts to finish orderly collection and conveying of vegetables, for example, patents CN201621390378.8, CN201910159271.4, CN201821348199.7 and CN201910127937.8, the basic structure of the device is that two opposite flexible conveyor belts travel in the same direction, an end supporting roller and a middle floating roller are used for enabling the conveyor belts to generate pretension, when vegetable stems are positioned between the two flexible conveyor belts, the conveyor belts generate bending deformation, and at the moment, the tension of the conveyor belts can apply pressure to the stems so as to generate clamping force. When the size of the vegetable stem is changed or the vegetable stem is clamped and conveyed at different positions, the bending deformation included angles generated by the flexible belts are different, so that the clamping force of the conveying belt on the vegetable stem is changed. And stem stems of the stem-leaf vegetables are soft and fragile, so that the stem leaves are brittle when the clamping force is too large, and the vegetables fall off when the clamping force is too small, so that the suitable clamping force range of each vegetable is different and smaller. Therefore, the existing clamping and conveying mechanism is difficult to adapt to the working occasions with large changes of the sizes of the stems due to uneven clamping force, and the damage rate is high. When the structure is used among different varieties of vegetables, the structure needs to be adjusted, so that the universality is low. In order to overcome the defects of the prior art, a clamping and conveying device with equal contact stress is developed, which is disclosed in patent No. CN202021209453.2 and is named as an equal contact stress clamping conveying device, the contact stress of the conveying mechanism and the vegetable stems is basically kept unchanged so as to adapt to different vegetables, but the mechanism has the defects of high air consumption and complex structure in practical application.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides the self-sealing clamping conveying device which is simpler in structure and smaller in air consumption.
The utility model provides a self sealss centre gripping conveyor, including the conveying mechanism of two sets of symmetrical arrangement about, every group conveying mechanism is including a pair of tandem initiative gyro wheel and driven cylinder, encircle in main, the outer conveyer belt of driven cylinder, be provided with the gasbag body in the conveyer belt outside, be provided with the air vent of mutual intercommunication on conveyer belt and gasbag body, be provided with the support air duct in the conveyer belt and main, cavity that driven cylinder encloses, be provided with the gas outlet of communicating the conveyer belt on supporting the air duct, the last air vent of gasbag body, its characterized in that: the air bag body is arranged on the conveying belt in a pre-stretching mode.
According to the self-sealing clamping conveying device, the air bag body is arranged on the conveying belt in a pre-stretching mode, and the inner cavity of the pre-stretched air bag body is in a close contact state at the roller under the action of tensile stress, so that the effect of isolating and sealing can be achieved, and a front compression roller and a rear compression roller which are used for compressing the air bag body on the conveying belt and can rotate per se do not need to be arranged at two ends of the conveying mechanism like the CN202021209453.2 patent. Therefore, the structure can be greatly simplified, the equipment cost is reduced, and the maintenance cost is reduced.
A sealing plate is arranged on the outer side of the conveying belt at the side of the air outlet of the supporting air duct.
The sealing plate arranged on the outer side of the conveying belt supporting the air outlet side of the air guide pipe can reduce air leakage, so that the air bag bodies on the air outlet side can be inflated more easily by compressed air until the two air bag bodies in bilateral symmetry contact each other.
The sealing plates on the outer side of the conveying belt are arranged on the upper side and the lower side of the air outlet of the conveying belt.
The sealing plate is of an L-shaped structure, one side of the sealing plate presses the conveying belt, and the other side of the sealing plate presses the supporting air duct.
The sealing plate with the L-shaped structure can better position the conveying belt, thereby strengthening the sealing effect.
The supporting air duct is a rectangular tube.
The sealing plate is matched with the rectangular supporting air guide pipe, so that the air outlet side conveying belt can form a better sealing surface to reduce air leakage when in work.
In summary, compared with the prior art, the invention has the following advantages:
(1) the self-sealing clamping conveying device adopts the pre-stretching air bag body, and the pre-stretching stress is utilized to enable the air bag body to automatically generate the sealing surfaces at the rollers at the two ends to form the self-sealing performance, so that the sealing structure is greatly simplified, and the production cost and the maintenance cost are reduced.
(2) The sealing plate at the air outlet of the air guide pipe is supported to improve the sealing effect and reduce the air consumption.
(3) Because the conveyer belt outside of gas outlet side is equipped with the closing plate, the conveyer belt is inboard and the rectangle support frame has great contact surface, all has sealed effect, consequently also has better sealed effect under less atmospheric pressure. The gas pressure can be adjusted in a large range to adapt to different vegetable varieties. The defect that the prior equal contact stress clamping and conveying device can generate stable sealing only by filling the air bag bodies to be mutually contacted is overcome.
