Description

Technical Field

[0001] The invention relates to the technical field of blow molding tube cutting, in particular to a centrifugal blow molding tube cutting device. Background Art

[0002] Blow-molded plastic tubes have closed "caps" at both ends. These caps need to be cut off before use, ensuring the cut ends are flush and smooth. Currently, the most common method for cutting blow-molded tubes is to transfer them to the processing workshop after blow molding, where the caps are cut with a circular saw or band saw. The tubes are then placed on a dedicated flattening machine for flattening, ensuring a smooth, even cut surface.

[0003] After searching, we have found a process for cutting both ends of blow-molded pipe fittings in a mold with publication number CN109624271A. The process includes a mold body and a cutting device for cutting. The mold body is provided with a front mold and a rear mold, and a mold cavity is provided between the front mold and the rear mold. The process is used to solve the problem of adding an additional semi-finished product link in the production process, extending the production cycle, and requiring a certain amount of manpower and equipment. At the same time, due to the existence of post-processing, the product size is unstable and defective products are inevitable. The invention has the following problems in use:

[0004] First, the in-mold cutting process has high requirements for equipment and molds. It is difficult to expand and implement on traditional blow molding machines. It cannot be processed on the equipment and molds of traditional blow molding machines. If it is forced to use, the efficiency is low and it is greatly restricted by labor and equipment.

[0005] 2. The tool cannot detect the clamping condition of the pipe during the cutting operation, which may easily cause safety hazards due to the proximity of other personnel or equipment, and the operation safety is low;

[0006] 3. The tool cannot be adjusted for applicability, and its applicability to blow molded tubes of different specifications and wall thicknesses is poor.

[0007] In summary, the present invention provides the centrifugal blow molding tube cutting device. Summary of the Invention
