Technical Field

[0001] The utility model relates to the technical field of plastic blister mold edge cutters, in particular to an adjustable plastic blister mold edge cutter. Background Art

[0002] Blister molds are widely used in the plastic processing industry, especially in the manufacture of various plastic packaging, containers and components. During the blister molding process, there are certain burrs around the prepared products. The burr area is also called the bladder edge. At this time, it is necessary to cut the bladder edge so that the plastic product after cutting can reach the required size and shape.

[0003] When performing cutting operations, corresponding cutters are usually required, and the number of cutters is generally two. However, when in use, conventional cutters are fixed to corresponding frames. There is a defect that the distance between the two cutters cannot be adjusted, and it is not possible to flexibly adjust according to specific needs. This results in the need to replace the entire cutter assembly when processing plastic products of different sizes, which increases production costs and processing time and brings inconvenience to users. In view of this, we propose an adjustable cutter for the edge of the blister mold. Utility Model Content

[0025] When in use, the second servo motor 15 is used to drive the forward screw rod 151 and the reverse screw rod 152 to rotate, thereby adjusting the distance between the two cutters 23. The first servo motor 12 is used to drive the support plate 13 to rotate, so that the cutter 23 can be reversed. The cylinder 1 is used to drive the bottom plate 11 to move, thereby driving the cutter 23 to move downward to achieve the cutting operation.

[0026] In this embodiment, the size of the slider 16 is adapted to the size of the slide rail 14, and the outer spirals on the surfaces of the forward screw 151 and the reverse screw 152 have opposite rotation directions, so that the two sliders 16 inside the same slide rail 14 can move in opposite directions, further realizing the adjustment operation of the distance between the two cutters 23.

[0027] Specifically, the telescopic shafts of the two cylinders 1 are fixedly mounted with rectangular plates 10, and the two rectangular plates 10 are fixed to the ends of the top surface of the base plate 11 via multiple fastening bolts.
