Gasket belt turn-over mechanism and double-conveyor type gasket turn-over machine

Abstract

The invention discloses a gasket belt turn-over mechanism, and belongs to the technical field of gasket detection. The gasket belt turn-over mechanism is used for wrapping the end head of a belt conveyor, the wrapping surface of a turn-over belt in the belt turn-over mechanism is of a V-shaped structure, and the upper end and the lower end of the V-shaped structure extend out of the tangent point of a conveying belt and a belt conveying roller, so that the attaching length of the turn-over belt at the feeding end of the belt turn-over mechanism and the conveying belt is increased, then gaskets can be clamped in advance, the gasket conveying distance is reduced, and the continuous feeding efficiency is guaranteed; meanwhile, the attaching length of the belt turn-over belt at the discharging end of the belt turn-over mechanism and the conveying belt is reduced, the gaskets are released in advance, at the moment, the lower end of the belt turn-over mechanism is fixedly connected with a discharging sliding way for bearing discharged materials of the belt turn-over mechanism, the discharging sliding way is attached to the lower end of the V-shaped structure, the gaskets released in advance enter the discharging sliding way and freely slide, and therefore the discharging speed is greatly increased, and the gasket turn-over detection efficiency is effectively improved under the double acceleration of feeding and discharging.

Description

technical field [0001] The invention relates to the technical field of gasket detection, in particular to a gasket belt turning mechanism and a double-conveyor type gasket turning machine. Background technique [0002] Washers are widely used in various industries such as machinery, electronics, vehicles, ships, and chemicals. They are parts that are placed between the connected parts and the nuts. In the manufacturing process of gaskets, gaskets need to be selected before they are counted and stored in order to remove gaskets with surface defects (such as cracks, pits, and defects on the surface) to ensure the quality of gaskets. The existing selection method is Place the gasket on the conveyor belt of the slow-speed conveyor, and select it by employees on both sides of the conveyor belt. During the selection process, the employee first checks one side of the gasket, and then the other side. If there is no defect, it will be sent by the conveyor belt. To the counting devic...

Problems solved by technology

Since each gasket has to be turned over once, the time for inspecting gaskets is basically spent on manual turning over, especially the gaskets with small thickness and large area are not easy to pick up, which makes the efficiency of selecting gaskets very low, making production Costs have risen sharply

[0003] In order to solve the above problems, such as the patent No. "201521115984.4", the invention patent titled "Double Conveyor Type Gasket Automatic Flip Device" realizes the flipping of the gasket by setting the upper and lower conveyors to cooperate with the steering plate, but this method It is too simple, and the structure has certain defects, and sometimes it is easy to fail to turn over

In order to solve the problem that it cannot be 100% turned over, the invention with the patent number "202010264670.X" and the name "a turning wheel installed on a fully automatic tablet turning mechanism" proposes a medicine turning mechanism. The mechanism includes a belt conveyor and an overturning mechanism wrapped at the end of the belt conveyor. The belt conveyor roller at the end of the belt conveyor is replaced by an overturning wheel. The overturning mechanism includes three overturning rollers and an overturning belt, of which two overturning rollers Located above the turning wheel, the other turning roller is located below the turning wheel and extends to the feeding direction of the belt conveyor to form a discharge conveyor belt. The turning mechanism can ensure 100% turning over, but the positions of the three turning rollers and The large size of the turning wheel causes the turning belt at the feed end of the turning mechanism to fit the conveyor belt only at the position where the turning wheel will turn over, so that the tablet will only be clamped by the turning belt when it enters the position where the turning wheel is going to turn. When the tablet is clamped at this position, one end of the tablet is bound to be tilted, so that when the tablets are continuously input, the rear tablet can only enter after the previous tablet has completely entered the clamping surface of the turning belt and the conveyor belt. As a result, the two tablets arranged front and back must have a certain distance, and at the same time, the turning belt at the discharge end fits too long with the conveyor belt, and the tablets can only be discharged slowly under the grip of the belt. In the case of slow speed, the detection efficiency cannot be guaranteed
