Description

Technical Field

[0001] The present invention belongs to the technical field related to plastic product processing, and in particular relates to a plastic product production and processing equipment and a process thereof. Background Art

[0002] The post-molding processing device of molding materials is a device used to further process and handle the already formed sheet plastics. After the initial molding of sheet molding materials (such as sheets, films, etc.), some subsequent processing is often required to meet the requirements of the final product. After the molding of bowl-shaped sheet plastics, a trimming device is required to perform precise edge trimming to ensure the quality and performance of the final product.

[0003] After searching, the applicant found a Chinese invention patent with patent publication number CN119078066A, entitled "A device for post-molding processing of sheet molding plastics". The device can fix the sheet molding fan by setting a fixing mechanism. When the sheet molding fan is placed on the placement table, the hydraulic cylinder pushes the semicircular connecting plate to move upward, and at the same time, the semicircular connecting plate pushes the third connecting rod, the connecting annular plate, and the second connecting rod to move upward. At the same time, the second connecting rod pushes the first sliding ring, the I-shaped annular connecting ring, the second sliding ring, and the inclined push plate to move upward, so that the inclined push plate will push the top block out from the inside of the second connecting rod, thereby fixing the sheet molding fan through the top block extending outward; however, when the above device is actually used, there are some shortcomings. When the bowl-shaped sheet plastic is trimmed, its edge needs to be trimmed into an edge with a certain curvature so that it has a better appearance and better use.

The clamping curved rod (106) can clamp the bottom of the plastic product body (3) under the elastic force of the first spring (105) to initially ensure stability. The output end of the downward pressure cylinder (201) drives the downward pressure plate (204) downward, drives the downward pressure roller (207) downward, and the downward pressure roller (207) contacts the plastic product body (3), which can ensure that the plastic product body (3) is in the center position. Step 2: According to the height and diameter of the plastic product body (3), the positions of the adjusting column (401) and the adjusting frame (403) are adjusted by connecting the bolts (407), and the positions of the adjusting frame (403) and the connecting block (405) are adjusted by connecting the bolts (407), so as to adapt to plastic product bodies (3) of different heights and diameters, so that the trimming head (5) contacts the edge of the plastic product body (3); Step 3: The rotation of the power motor (6) drives the rotating gear (301) to rotate, which in turn drives the rotating ring (303) to rotate, and then drives the trimming motor (4) to rotate. The rotation of the power motor (6) drives the rotating block (505) to rotate. The rotating protrusion (506) provided on the rotating block (505) contacts the moving block (507) and drives the moving block (507) to move, compressing the second spring (514). The guide block (511) moves along the direction of the guide rod (513). The adjusting plate (509) contacts the adjusting inclined plate (504), driving the adjusting inclined plate (504) to rotate, and driving the rotating plate (501) to rotate. Because the rotating protrusion (506) contacts the moving block (507) only once in each adjustment cycle, the rotating plate (501) only rotates to adjust the displacement of the inclined plate (504). After the rotating plate (501) rotates, it is limited under the limit of the limit rod (605), and the trimming motor (4) and the trimming head (5) perform a trimming operation at another angle; when it is necessary to restore the rotating plate (501) to its original position, the torsion spring (607) is compressed by the push plate (609), so that the limit rod (605) is disengaged from the limit groove (602), and the rotating plate (501) can be driven to rotate at this time, and it can be rotated back to the required starting position.
