TECHNICAL FIELD
[0001] The utility model relates to PP board polishing technical field, concretely is a PP board burr polishing device. BACKGROUND
[0002] PP board, also known as polypropylene (PP) board (PP pure board, modified PP board, reinforced PP board, PP electrode), is a kind of semi-crystalline material. It is more hard than PE and has a higher melting point. In the production process of PP board, a large number of burrs are easily generated at the edge, which affects the overall quality of the PP board and also affects the appearance of the PP board, so it needs to be polished by polishing equipment.
[0003] The existing polishing equipment needs to make the edge of the plate closely contact with the polishing wheel when the edge is trimmed, and because the sizes of the plates are different, single-side polishing is generally adopted. After the polishing of one side of the PP board is completed, the plate is rotated or turned over to make the unpolished side closely contact with the polishing wheel for continuous polishing. However, because the sizes of the plates are different, the thicknesses and weights of the plates are not equal. When the edge of the heavy plate is changed, it is difficult to quickly change the edge of the plate, and a lot of manpower is needed. UTILITY MODEL CONTENTS
