transmission

Abstract

The invention discloses a transmission device. The transmission device includes a conveying line. The conveying line is parallelly provided with multiple product bearing parts in the conveying direction. The transmission device further includes an electromagnetic part and a restoration part. The product bearing parts are provided with accommodating holes and are further provided with bearing bottom plates. One end of each bearing bottom plate is provided with a rotation shaft. The middle of each bearing bottom plate is provided with a bearing part. The other end is parallelly provided with a first magnet attracting part and a second magnet attracting part. The bearing bottom plates are connected with the product bearing parts in a rotation mode through a rotation shaft. The bearing parts cover the openings at the bottoms of the accommodating holes. The first magnet attracting parts are magnet-attracted to the product bearing parts. When the electromagnetic part is energized, M1 is larger than M2, in the formula, M1 refers to a torque relative to the rotation shaft of a magnet repulsive force between the electromagnetic part and the second magnet attracting part, M2 refers to a torque relative to the rotation shaft of a magnet attraction force between the conveying line and the first magnet attracting part. According to the transmission device, in this way, in the whole processof workpiece removing, energy dissipation is needed only when the electromagnetic part is open for a short time, so the energy dissipation is extremely small.

Description

technical field [0001] The invention relates to mechanical equipment, in particular to a transmission device. Background technique [0002] Conveyor line is one of the common equipment in the fields of industry, commerce, agriculture, etc. The products on the conveyor line, whether they are raw materials, semi-finished products, or finished products, almost inevitably have substandard products (defective products) due to various reasons. Most of the design In the conveying process of the conveyor line, the defective product detection device and the rejecting device are designed to remove the unqualified products. [0003] The rejecting devices in the prior art are divided into two categories, one is the rejecting device in a normal working state, such as the authorization announcement number is CN103258701B, the authorization announcement date is February 10, 2016, and the name is "Energy-saving lamps for round row cars". The invention patent of the method and equipment for...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the prior art is that, in order to eliminate defective products, it is necessary to maintain the normalized defective product removal mechanism in working condition, such as air extraction channels, push rod cylinders, etc., which require large energy consumption, and in most cases The proportion of defective products is very small, so it is more energy-consuming to maintain the working state of the defective product rejecting device in such a normalized manner
