Automatic pressing device with spring for mesh belt transmission chain

Abstract

The invention discloses an automatic pressing device with a spring for a mesh belt transmission chain. The automatic pressing device is connected to one side of the transmission chain, the transmission chain comprises a plurality of pin shafts and connecting parts, and each connecting part is used for connecting every two pin shafts. The automatic pressing device comprises a pressing wheel, a swinging arm, a fixed support and a spring adjusting device, wherein gears of the pressing wheel are meshed with the pin shafts of the transmission chain; the pressing wheel is fixedly connected onto the fixed support through the swinging arm, and the swinging arm rotates by taking the fixed support as a rotation center; the spring adjusting device is perpendicularly connected to one side of the swinging arm, and is arranged at one end close to the pressing wheel; the spring adjusting device comprises a support rod connected onto the swinging arm, a spring sleeving the outer side of the supporting rod, and a support used for fixing the other side of the supporting rod. Through the adoption of the automatic pressing device provided by the invention, the phenomenon that the temporary halt of the transmission chain is caused by transmission chain looseness during the long-time operation process of the mesh belt transmission chain is avoided, the transmission efficiency of the mesh belt transmission chain is improved, the working efficiency of the mesh belt transmission chain on a food industry automatic production line is particularly improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of food production and transmission, in particular to a spring automatic pressing device for a mesh belt transmission chain. Background technique [0002] The transmission chain structures commonly used in the automatic production lines of the food industry in the prior art include hollow pin shaft chains and self-lubricating chains, wherein the hollow pin shaft chains are used for conveying, and single pitch, double pitch, and long pitch are all available. The attachment or crossbar can be inserted into any link of the chain without dismantling the chain; the self-lubricating chain parts are made of a sintered metal soaked in lubricating oil, the chain has excellent wear resistance and corrosion resistance, and does not require maintenance (maintenance-free). Long life characteristics. It is widely used in occasions with high stress, wear resistance requirements, and frequent maintenance, such as automati...

Problems solved by technology

[0003] However, for the conveyor chain on the recipe industrial automation production line used for long-distance transmission, the phenomenon of chain slack often occurs during the long-distance transmission process. At present, it is often manually maintained and maintained, although anti-loosening alarms are installed on the transmission device. equipment to ensure the normal operation of the automated production line, but people are also inseparable from the production line, and debugging takes time, and the efficiency of food transportation will be greatly reduced

Affects the productivity of food production lines
