Technical Field

[0002] According to the direction of the material flow in the die and the angle between the center line of the screw, the die head of the extruder can be divided into a right-angle die head and a bevel die head, etc. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and rare multi-screw extruders and screwless extruders. The threaded elements of the extruder will be ground using a grinding device. There are at least the following disadvantages in the use of existing grinding devices: 1. After long-term use, the grinding belt on the existing grinding device is easily worn, affecting the grinding effect, and the removal and replacement of the grinding belt is inconvenient, reducing practicality; 2. The existing grinding device has a poor fixing effect on the threaded elements of the extruder, which causes the threaded elements of the extruder to shake easily during the grinding process, resulting in grinding errors, affecting the quality of the threaded elements of the extruder. Therefore, we introduce a surface grinding device for the threaded elements of the extruder. Utility Model Content

Abrasive belt wheels 10 are movably connected to the upper part and the lower part of the left end of the support frame 9 through bearings respectively. A driving mechanism 11 is inserted and movably connected to the middle of the rear frame wall of the support frame 9. A grinding abrasive belt 12 is jointly sleeved between the outer surface of the driving mechanism 11 and the outer surfaces of the two abrasive belt wheels 10.

[0024] In this embodiment, the driving mechanism 11 includes an electric push rod 111. The output end of the electric push rod 111 penetrates through the rear frame wall of the support frame 9 and is fixedly connected with a moving frame 112. A driving motor 113 is arranged at the rear part of the right end of the moving frame 112.

The left end and the right end of the driving wheel 114 are movably connected with the left frame wall and the right frame wall of the moving frame 112 through bearings respectively; the moving frame 112 is arranged in a C-shaped structure. The diameter length of the driving wheel 114 is the same as the diameter length of the two abrasive belt wheels 10, which is convenient for driving the grinding abrasive belt 12; the controller 7 is electrically connected with the driver 4, the electric push rod 111 and the driving motor 113.

[0025] In this embodiment, the fixing mechanism 6 includes an adjustment frame 61.
