Intermittent conveying device provided with brake mechanism and used for mask production line

Abstract

An intermittent conveying device provided with a brake mechanism and used for a mask production line comprises a machine body, a driving roller is installed on the lower portion in the machine body, and a brake assembly is arranged on the outer side of the driving roller. According to the device, through clearance fit between a sliding rail and a sliding rod and symmetrical arrangement of inclined plates and brake pads relative to the driving roller, when an external control module controls an air cylinder to contract, the inclined plates rotate inwards and drive the brake pads to abut against the two sides of the outer wall of the driving roller, the braking effect on the driving roller is achieved, rapid braking is achieved, then, intermittent processing of masks is facilitated, and the processing precision is improved; and the process occurs before the brake pads abut against the driving roller, a gear can be meshed again during reverse operation, then damage caused by sudden stop of a motor is avoided, the motor is protected, the service life of the motor is prolonged, sliding blocks can drive the brake pads to be rapidly replaced, the braking effect is guaranteed, and the machining efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of an intermittent transmission device with a brake mechanism for a mask production line, in particular to an intermittent transmission device with a brake mechanism for a mask production line. Background technique [0002] In order to make the mask effectively prevent air from entering the nose directly from the gap between the mask and the nose without passing through the mask, a soft strip is added to the bridge of the nose of the mask. Enter the nose through here, but there is no equipment on the market that can realize the above functions, all of which are manually processed, and the labor cost is high, so a mask production line is required, and a brake mechanism is essential in the production line.

[0002] In order to make the mask effectively prevent air from entering the nose directly from the gap between the mask and the nose without passing through the mask, a soft strip is added to the bridge of the nose of the mask. Enter the nose through here, but there is no equipment on the market that can realize the above functions, all of which are manually processed, and the labor cost is high, so a mask production line is needed, and the brake mechanism is essential in the production line

[0003] In the prior art, the discontinuous transmission device with a brake mechanism used in the mask production line has a poor braking effect on the driving roller, and cannot achieve fast braking and stopping, which is not convenient for intermittent processing of the mask, which affects the processing accuracy. At the same time, it is not convenient to repair and maintain the internal components of the machine body. It is impossible to separate the motor from the transmission before the driving roller stops, which will easily cause the motor to stop suddenly and cause damage. It cannot protect the motor and shorten the service life of the motor. It is impossible to quickly replace the brake pads, and the braking effect cannot be guaranteed, which further affects the processing efficiency and is inconvenient for people to use
