Description

TECHNICAL FIELD

[0001] The utility model relates to transmission mechanism technical field, concretely is adjustable width's multi -position transmission mechanism. BACKGROUND

[0002] The fruit and vegetable packaging machine is a kind of mechanical equipment for the automatic packaging of fruits and vegetables, and is widely used in the fields of agricultural product processing, logistics transportation and supermarket sorting. Through the fruit and vegetable packaging machine, the bagging and sealing packaging process of fruits and vegetables can be efficiently completed, the production efficiency is greatly improved, the labor intensity is reduced, and the appearance and quality of fruits and vegetables during transportation and sales are ensured.

[0003] In the operation process of the fruit and vegetable packaging machine, the feeding transmission mechanism is one of the key links, which functions to convey the fruits and vegetables to be packaged to the packaging equipment through the transmission device. In order to ensure the efficiency of feeding, a workbench is usually provided on both sides of the conveying belt of the transmission mechanism for multiple workers to use. The workers place the fruits and vegetables to be packaged into the fruit and vegetable basket on the workbench, and then place the fruit and vegetable basket neatly on the conveying belt, which is then smoothly conveyed to the packaging machine for subsequent processing.

[0004] In the prior art, the width of the conveying belt of the transmission mechanism is usually designed to be slightly wider than the width of the fruit and vegetable basket to ensure that the conveying belt can stably carry the fruit and vegetable basket and smoothly complete the transmission. However, when the model of the fruit and vegetable basket changes, the width of the conveying belt may be too large or too small relative to the width of the fruit and vegetable basket. If the width is too large, the fruit and vegetable basket may tilt or deviate during transmission; if the width is too small, the fruit and vegetable basket cannot be placed or transmitted normally. In order to solve this problem, the entire transmission mechanism usually needs to be replaced or the conveying belt needs to be adjusted complicatedly, which not only increases the cost of equipment modification, but also reduces the production efficiency, which is not conducive to the flexible use of the equipment. Therefore, we propose a multi-station transmission mechanism with adjustable width. SUMMARY
