Description

An automatic rejecting machine

technical field

The utility model relates to the technical field of automatic sorting equipment, in particular to an automatic rejecting machine.

Background technique

In the automatic packaging production line, the automatic rejecting machine can automatically detect unqualified products, and push them to the conveying line of the picked out products through the automatic rejecting device to prevent them from continuing to enter the qualified product output line.

In the prior art, the automatic rejecting machine is installed between the product detection line and the qualified product output line, including a frame with conveying rollers installed at the rejecting station, and installed on one side of the frame at the rejecting station, and The pick-up product conveying line perpendicular to the conveying direction of the qualified product is equipped with an automatic rejecting device on the frame at the rejecting station, wherein the automatic rejecting device includes a rejecting plate, a cylinder, a slide rod and a slide rod bearing, and the rejecting plate is vertically installed on the In the gap between the conveying rollers, the upper end of the rejecting plate is provided with a push plate, and the lower end is provided with a base for installing the push plate. The base is located below the conveying roller. The rod and the sliding rod are parallel to each other and are perpendicular to the rejecting plate. The sliding rod bearing matches the sliding rod and is installed on the side of the frame where the output line of the picked-up product is connected to play a role of supporting and guiding the movement of the sliding rod. Non-working state, the cylinder rod shrinks, and the rejecting plate is located on the side of the frame far away from the output line of the picked product. When the automatic detection device detects unqualified products, the signal is transmitted to the cylinder drive system of the automatic rejecting device, and the cylinder rod stretches out to push The reject rod moves forward, and at the same time, the two slide rods slide axially in the slide rod bearings, and the unqualified products are pushed to the pick-up conveyor line under the action of the reject plate.

However, in the above structure, the sliding rod bearing is fixed and the sliding rod moves. In actual installation, there is no connector for directional installation of the cylinder rod on the rejecting plate. When the cylinder rod and the two sliding rods are not installed in absolute parallel, the sliding rod bearing is easily damaged; The installation structure of the connection between the cylinder rod and the rejecting plate is compact, the gap is small, and it is inconvenient to maintain; the sliding rod moves while the sliding rod bearing is fixed and supported by one point, resulting in unstable movement of the rejecting plate, high failure rate and short service life.

To sum up, how to further improve the automatic rejecting device, increase its structural stability, further reduce the failure rate, and prolong its service life has become a technical problem to be solved urgently by those skilled in the art.

The automatic rejecting machine provided by the utility model comprises a frame located at the rejecting station and provided with several conveying rollers, a rejecting plate, a cylinder, a slide bar and a slide bar bearing, the two ends of the slide bar are fixed on the frame, and The projections on the same horizontal plane as the conveying roller are parallel to each other. The sliding rod bearing is fixed on the rejecting plate and sleeved on the sliding rod. The cylinder rod of the cylinder is fixed on one side of the rejecting plate and is used to push and pull the rejecting plate to move along the sliding rod. When the cylinder control system receives the rejection signal, the cylinder rod extends, pushes the rejection plate through the slider bearing fixed on it, and slides forward along the fixed slider to realize the rejection of unqualified products. After completion, reset and wait For the input of the next signal, in the above structure, the fixed slide bar plays a guiding role. Compared with the existing technology, the point support during the movement is converted into a line support, which makes the push-pull movement more stable, reduces the failure rate, and prolongs the The service life of the equipment.
