Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic cutting tables, and more specifically, to a plastic product waste material cutting table. Background Art
[0002] Blow molding technology is a rapidly developing plastic processing method. The bottle-shaped plastic preform obtained after the thermoplastic resin is molded by base or injection molding is placed in a split mold while hot. After the mold is closed, compressed air is immediately introduced into the preform to inflate the plastic preform and cling to the inner wall of the mold. After cooling and demolding, various hollow products are obtained. The blow-molded product needs to be cut through a cutting table to remove the excess part of the bottle mouth, and then placed in a trimming device for trimming. At present, many cutting tables are generally set horizontally when clamping and fixing plastic bottles, which makes it difficult to install and disassemble plastic bottles near the center of the workbench, and the operation is difficult; in addition, when clamping and fixing plastic bottles, the current cutting table generally uses three clamping blocks to clamp the plastic bottles in three directions at the same time, but different plastic bottles have different curvatures, and it is difficult for the clamping blocks to meet the stable clamping of various plastic bottles, and the clamping stability is poor.
