Automatic deviation rectifying and discharging device for abrasive paper

Abstract

The invention discloses an automatic deviation rectifying and discharging device for abrasive paper. The automatic deviation rectifying and discharging device is composed of a plurality of dischargingframe modules; and each discharging frame module comprises a chassis, an abrasive paper cylinder, a movable support, an abrasive paper tensioning device and an automatic deviation rectifying device,wherein the abrasive paper cylinder is rotatably arranged on the movable support, the movable support can linearly move on the chassis under the driving of a hydraulic oil cylinder, the abrasive papertensioning device is arranged at the position, on the side, in the abrasive paper conveying direction, of the abrasive paper cylinder, of the chassis, the automatic deviation rectifying device comprises a photoelectric sensor and an automatic deviation rectifying control cabinet, the photoelectric sensor is used for sensing the positions where the edges of the two sides of the abrasive paper in the conveying process are located, the automatic deviation rectifying control cabinet is electrically connected to the photoelectric sensor and the hydraulic oil cylinder, and a guide roller is furtherarranged on the position, on the side, in the abrasive paper conveying direction, of the abrasive paper tensioning device, of the chassis. The automatic deviation rectifying and discharging device has the advantages that each layer of abrasive paper can be automatically subjected to deviation rectifying without manual operation, and therefore the production efficiency is improved, the product reject ratio is decreased, and material waste is avoided.

Description

technical field [0001] The invention relates to the field of sandpaper manufacturing equipment, in particular to an automatic deviation-correcting and discharging device for sandpaper. Background technique [0002] Generally, in the sandpaper production line, there is a base paper compounding process that is more important. It directly affects the quality of the entire sandpaper product. The specific operation process is to glue several rolls of base paper with the same size and shape together to form a composite sandpaper regardless of hardness, strength or strength. Base paper with significantly enhanced other physical properties. Several rolls of backing paper need to be aligned and conveyed on a discharge rack before gluing, but the tension on the backing paper is uneven due to the lack of unwinding power on the discharge rack, making the surface wrinkled and the backing paper will inevitably be damaged during transmission. The left and right deviations in the horizonta...

Problems solved by technology

Several rolls of backing paper need to be aligned and conveyed on a discharge rack before gluing, but the tension on the backing paper is uneven due to the lack of unwinding power on the discharge rack, making the surface wrinkled and the backing paper will inevitably be damaged during transmission. The left and right deviations in the horizontal direction cause uneven margins on both sides of the product, which seriously affects product quality. Most manufacturers avoid this problem by manual observation and manual correction. However, this solution is not only inefficient but also produces The quality of the product that comes out is not high
