Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grinding devices, and in particular relates to a plastic spraying layer grinding device. Background Art
[0002] The plastic spray layer grinding device is used to grind the plastic sprayed sheet metal parts, which is convenient for gluing after grinding and makes the adhesion between the glue and the sheet metal parts better. The grinding speed and height can be adjusted according to needs. After grinding the two opposite surfaces, the device can be lifted and rotated 90° to facilitate grinding the remaining two surfaces. However, the grinding depth of most existing grinding devices is uncontrollable, and the grinding position positioning and adjustment are cumbersome or cannot be adjusted.
[0003] Therefore, when using the existing grinding device, the grinding depth cannot be controlled, and the grinding depth will vary. If the grinding is too shallow, a second grinding will be required, which wastes work time, while if the grinding is too deep, the spray-coated layer will be completely worn away to expose the inner surface of the workpiece; and the existing grinding device is cumbersome to adjust the grinding position, which is basically for large-area or full-surface grinding, and cannot grind a fixed position of the workpiece.
[0004] For example, a Chinese invention patent with application publication number CN 105538068 A discloses an end face grinding device for a metal plate before plastic spraying, which clamps the metal plate by setting a clamping cylinder 2 to connect a clamping plate 3, then the grinding motor 6 moves downward, and the grinding head 7 grinds the top surface of the metal plate. The grinding position is adjusted by setting a clamping block 9 to clamp the two ends of the metal plate and slide on a sliding track 8, and an air blowing pipe 13 is provided to blow away the grinding dust, and a dust suction hood 14 is provided to absorb the dust; however, the disadvantage is that it requires frequent manual surface changing and grinding, and the work efficiency is low.

[0017] 4. The function of the spring is to tighten the annular abrasive belt. The function of the annular abrasive belt is to grind the workpiece by cooperating with the contact grinding belt wheel. The function of the sheet metal part is to fix the contact grinding belt wheel and the spring.
[0018] 5. The functions of the contact grinding belt wheel are: first, it is used to tighten the annular abrasive belt, and second, it is used as a contact wheel when grinding together with the annular abrasive belt;
[0019] To summarize, the rotation of the motor drives the pulley to rotate, and drives the annular sanding belt to rotate at high speed, and the workpiece is placed at the specified position on the conveyor plate.
