Detailed Description
The invention is described in more detail below with reference to the accompanying drawings. A blow-molded article flash trimming mechanism, characterized by: the plastic product cutting machine comprises a positioning seat, a plastic product 1 is fixed in the positioning seat, and further comprises a triaxial servo driving table, a cylinder 2 and a rack 3 driven by the cylinder 2 are mounted on the triaxial servo driving table, a gear 4 meshed with the cylinder is arranged on the rack 3, a central shaft 5 of the gear 4 is connected with the triaxial servo driving table and a connecting block 6, the rack 3 is connected with the cylinder 2 and driven by the cylinder, the connecting block 6 is driven to swing through the gear 4 during movement of the rack 3, one end of the connecting block 6 is connected with the gear 4, the other end of the connecting block is connected with a cutter bar 7, a blade 8 is mounted at the top end of the cutter bar 7, and the blade 8 moves along the outline of the plastic product 1 under the driving of the triaxial servo driving table and the gear rack, so that burrs on the outline of the plastic product 1 are cut.
The connecting block 6 is waist-shaped, one end of the connecting block is fixed with the central shaft 5 of the gear 4, the other end of the connecting block is provided with a guide groove 61, and the cutter bar 7 can be arranged in the guide groove 61 in a swinging mode.
A torsion spring 62 is installed in the guide groove 61, one supporting leg of the torsion spring 62 is positioned in the guide groove 61, the other supporting leg is installed in the cutter bar 7, and the torsion spring 62 generates thrust to drive the cutter bar 7 to swing towards the groove lower direction of the guide groove 61 all the time.
The top end of the cutter bar 7 is provided with a cutter groove 71, and the cutter blade 8 is detachably arranged in the cutter groove 71.
Working principle: the plastic product in the present case is fixed in a positioning seat (not shown in the figure), and the cylinder and the rack are fixedly installed on a triaxial servo driving table (not shown in the figure). The triaxial servo driving table drives the cutter bar to move along the outer contour of the plastic product under the action of the control system. The blade at the top end of the cutter bar is scraped along the outline of the product, and the flash on the product is removed.
As shown in fig. 1 and 2, some plastic products have an inner hole (the position of the handle of the product in the drawing), and when the flash on the inner hole needs to be scraped, the angle of the blade needs to be converted to adapt to the contour direction of the inner hole. At this time, the cylinder 2 drives the rack 3 to perform telescopic motion, thereby driving the gear 4 meshed with the rack to rotate, and when the gear 4 rotates, the connecting block is driven by the central shaft to drive the blade to deflect, so that the cutting angle of the blade is adapted to the scraping track.
Further: in order to uniformly force the blade on the plastic product and prevent the blade from scratching the product, the cutter bar 7 is arranged in the guide groove 61 in a swinging way. A torsion spring 62 is installed in the guide groove 61, one supporting leg of the torsion spring 62 is positioned in the guide groove 61, the other supporting leg is installed in the cutter bar 7, and the torsion spring 62 generates thrust to drive the cutter bar 7 to swing towards the groove lower direction of the guide groove 61 all the time. Therefore, the elastic force generated by the torsion spring forces the blade to be uniformly stressed on the plastic product, so that the scraping stability of the blade is ensured.
Compared with the prior art, the special blade driving structure in the scheme can enable the blade to automatically follow the outline of the product to move, and efficiently and stably scrape the flash on the product, so that the defects of low working efficiency, unstable quality and the like existing in the traditional technology due to manual cutting are avoided.
The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
