Description

Technical Field

[0001] This utility model belongs to the field of processing equipment for PET foam boards, and particularly relates to a rotating chamfering mechanism for PET foam board discs. Background Technology

[0002] PET foam board is a polyterephthalic acid plastic, also known as polyester board. This material has many advantages, including high mechanical strength, rigidity, and hardness; excellent sliding performance and wear resistance; good electrical insulation; creep resistance; and a low and stable coefficient of friction. Existing PET foam boards generally require chamfering, but current chamfering and grinding equipment has a fixed structure. Currently, the chamfering requirements for the PET foam boards extruded by our company vary depending on different customer needs, and the chamfering and grinding mechanism cannot adaptively adjust the angle or bevel according to different positional requirements. This results in inflexible chamfering tooling and time-consuming and labor-intensive processing. Utility Model Content

[0008] Furthermore, limiting grooves are respectively opened on the upper and lower rear sides of the positioning plate; the limiting grooves are respectively distributed corresponding to the threaded channel; T-shaped rods are respectively installed in the limiting grooves; the ends of the T-shaped rods extend into the threaded channel and are connected to the inner end of the locking bolt.

[0009] Furthermore, the positioning disk has an annular groove around its front side; the rotating disk has rotating blocks on its inner side, one above the other; and the rotating blocks are rotatably mounted on the annular groove.

[0010] Furthermore, the two arc-shaped slots opened on the upper and lower parts of the rotating disk form a circular trajectory, and the two arc-shaped slots are symmetrical about the center of the rotating disk.

[0011] Furthermore, the outer end of the locking bolt is provided with a pressing block, which presses against or separates from the outside of the rotating disk.

[0012] The beneficial effects of this utility model are as follows:

[0013] The rotating disk of this invention can rotate on the positioning disk, which can drive the grinding module to rotate, thus realizing the adjustment of the chamfer angle. After adjustment, the locking bolt is rotated and its outer end is pressed against the outside of the rotating disk, thus realizing the positioning of the rotating disk.
