Automatic feeding device of abrasive paper cutting machine

Abstract

The invention discloses an automatic feeding device of an abrasive paper cutting machine. The automatic feeding device comprises a rack, a movable clamping mechanism and two fixed clamping mechanisms;the two fixed clamping mechanisms are distributed on the two sides of the movable clamping mechanism and fixedly connected with the rack, and the movable clamping mechanism is slidably arranged on ascrew rack fixedly connected with the rack in a sleeving mode; and linear guide rails used for ensuring that the movable clamping mechanism linearly slides on the rack are fixedly installed on the rack, a front travel switch and a back travel switch are detachably connected to the lower end of the rack, distributed on the two sides of the movable clamping mechanism respectively and electrically connected with an electric appliance control cabinet, and the electric appliance control cabinet is electrically connected with the movable clamping mechanism and clamping executing parts arranged on the fixed clamping mechanisms. According to the automatic feeding device of the abrasive paper cutting machine, it can be guaranteed that the length of abrasive paper pushed every time is equal, and notonly can an undercut phenomenon be avoided between the last time of abrasive paper cutting and the next time of abrasive paper cutting, but also unnecessary waste of raw materials can be avoided.

Description

technical field [0001] The invention relates to the field of sandpaper manufacturing equipment, in particular to an automatic feeding device on a sandpaper cutting machine. Background technique [0002] In the production process of punching sandpaper (including other shapes), most manufacturers currently use a synchronous pulley mechanism to feed the sandpaper, but due to the small distance between the sandpaper disks, the feeding requirements The repetition accuracy is high, that is, the length of the sandpaper pushed by the feeding device must be the same after each punching is completed. If the pushing length is too large, it will cause material waste, and if the pushing length is too small, it will easily undercut. Therefore how to ensure that the length of the sandpaper that the feeding device pushes every time is equal is a problem worth studying. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide an au...
