Description

Sanding machine

Technical Field

The application relates to the field of cloth aftertreatment equipment, in particular to a sanding machine.

Background

The sanding treatment refers to that the surface of cloth is sanded by a sanding roller, the fiber on the surface of the cloth is cut off by carborundum on a sanding skin, and then the cut fiber is sanded into fluff, so that a short fluff layer appears on the originally smooth surface of the cloth, the hand feeling of the cloth becomes soft and comfortable, the texture is thick, and meanwhile, the warm keeping function of the cloth is also increased, therefore, the sanded cloth is often used for weaving clothes in winter.

Because the manufacturing amount of the cloth is large, the cost of embedding carborundum on the side wall of the sanding roller is too high, so the sanding roller usually tightly covers a layer of abrasive leather on the surface, then the abrasive leather can be installed on the sanding roller after the beginning and the tail end of the abrasive leather are mutually adhered, and the sanding roller sands the cloth through the abrasive leather.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: when the sand skin needs to be changed, the staff need be earlier manual take-up the sand skin, then be in the same place the beginning and the tail end adhesion of sand skin, because glue needs the certain time just can dry, and then make the sand skin need consume the longer time to can use the start after changing, reduced the work efficiency of sanding machine.

SUMMERY OF THE UTILITY MODEL

In order to solve and need the operating efficiency of certain time drying and then reduced equipment through glue with the sand skin adhesion together, this application provides a sanding machine.

The application provides a sanding machine adopts following technical scheme:

a sanding machine comprises a rack, wherein a sanding roller is rotatably arranged on the rack, an installation groove is formed in the side wall of the sanding roller, the length direction of the installation groove is parallel to the axis of the sanding roller, and the length of the installation groove is greater than the width of a common abrasive belt; the installation groove internal rotation install two with the parallel compression roller of mill hair roller, two be provided with the clearance that supplies husky leather paper to pass between the compression roller, be provided with the clamping mechanism who is used for pressing from both sides tight sand skin on the compression roller, still install fixed establishment and two on the mill hair roller the compression roller is connected.

By adopting the technical scheme, when the sanding leather on the sanding roller is excessively worn and needs to be replaced, a worker firstly separates the fixing mechanism from the two compression rollers, then reversely rotates the compression rollers to release the original sanding leather, then respectively takes off two ends of the old sanding leather from the clamping mechanism, takes off the sanding leather from the sanding roller, then winds a new piece of sanding leather on the sanding roller, respectively winds two ends of the new sanding leather on the two compression rollers, respectively clamps two ends of the new sanding leather on the two compression rollers through the clamping mechanism, can tighten the sanding leather by reversely rotating the two compression rollers, and can finish the tightening installation of the sanding leather after the sanding leather winds around a circle on the compression rollers, the sanding leather is more difficult to fall off from the rollers, and after the sanding leather is tightened, the two compression rollers are fixedly connected with the sanding roller through the fixing mechanism, the tightening installation is simpler, the efficiency is higher, the time consumed for replacing the abrasive leather is reduced, and the working efficiency of the sanding machine is improved.
