Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a simultaneous adjustment device for clamping a track. Background Art

[0002] In the field of industrial automation, clamping conveyor chains are widely used in various production lines and processing equipment as an important tool for material transmission. However, traditional clamping conveyor chains have many shortcomings in terms of adjustment. First of all, most traditional clamping conveyor chains use a single transmission mechanism, which makes it difficult to simultaneously and accurately adjust the position and speed of multiple clamping points. For example, if wine bottles of different sizes need to be produced, the clamping track will adjust the width in turn, resulting in a long adjustment time before production, which delays production efficiency; secondly, since the clamping conveyor chain usually needs to operate in a complex working environment, such as high temperature, high humidity, high dust and other environments, this puts higher requirements on the adjustment device of the clamping conveyor chain, which needs to have higher stability and reliability. In addition, with the continuous improvement of the degree of automation, higher requirements are also placed on the adjustment accuracy and speed of the clamping conveyor chain.

[0003] In order to solve the above problems, some new clamping conveyor chain adjustment devices have appeared on the market. However, most of these devices have complex structures and high costs, and the adjustment accuracy and stability still need to be improved. Therefore, it is of great practical significance and application value to develop a clamping track simultaneous adjustment device with simple structure, low cost, high adjustment accuracy and good stability.
