Device for separating paper

Abstract

The invention discloses a device for separating paper. After the paper is rubbed out through a paper rubbing wheel, a paper pressing piece in a rotary paper pressing air cylinder set presses exposed lower-layer paper, a suction cup frame moves to the preset position to suck the paper, in the paper sucking process, the suction cup frame adjusts the height and the width in the width direction of two rows of suction cups, and the sucked paper forms a shape that the edge sucked by the suction cups is high, and the middle which is not sucked by the suction cups is sunken. Meanwhile, in the position change process of the suction cups, shaking suction cups on the suction cup frame continuously shake at high frequency in the vertical direction; an air knife group continuously blows air to the lower part of the edge of the paper, through the above manner, the air among the paper is increased, and the lower-layer paper is prevented from being sucked and falls back into a paper pile; and in this way, when the suction cup frame sucks top-layer paper to move to the preset position, all components of the device are ready to start to separate the next paper. Through mutual cooperation of various components and manners, the paper is not prone to being tightly attached together after air enters the paper, and therefore stable, reliable, efficient and convenient paper separation is achieved.

Description

technical field [0001] The invention relates to the field of automatic paper separating equipment, in particular to a device for separating paper. Background technique [0002] In the process of PCB board production, when receiving the board in some processes, in order to prevent the board surface from being crushed, it is necessary to place a layer of spacer paper under the board. Remove one by one and place under the plate. The traditional paper suction mechanism only uses the suction cup holder with a vacuum suction cup to directly absorb the paper. This method is prone to the phenomenon of two sheets. After the lower paper is biased, the subsequent suction cup holder cannot pick up the paper accurately. In fact, the root cause of "continuous sheets" is that the paper is breathable, so when the vacuum suction cup sucks the first sheet of paper, the air between the following sheets of paper is also drawn out, causing the air pressure to decrease, and the following sheets ...

Problems solved by technology

But the pre-absorbing paper assembly in this patent is also easy to suck up multiple sheets of paper, and the main function of the suction cup of the paper-absorbing fixture is the middle of the paper, and the air is not easy to replenish into the paper; although a blowing tube is set to make the top paper fluffy , but in order to prevent the paper pieces from being blown away, the auxiliary separation screw set limits the bulkiness of the paper, so the patented device is still easy to pick up multiple sheets of paper, and the work is not stable and fast enough.
