Technology for directly driving transferring apparatus by pouring-blowing hollow molding machine servo motor

Abstract

The invention discloses a technology for directly driving transferring apparatus by a pouring-blowing hollow molding machine servo motor, which comprises a work bench, a turret is arranged on the work bench, the turret is directly connected to the servo motor through a main shaft, the main shaft and the servo motor are coaxially arranged, the servo motor is connected to a connection disc, and the connection disc is connected to the work bench. According to the invention, the main shaft is directly driven by the servo motor, intermediate transmission link is reduced, energy loss is reduced, energy utilization rate is high, usage space is reduced, ventilation space is increased, and the ventilation and heat radiation performances are good.

Description

technical field [0001] The invention relates to the technical field of injection-blow molding machines, in particular to a direct-driven indexing device for a servo motor of an injection-blow molding machine. Background technique [0002] Using plastic (mainly PE, PP, PS, etc.) The existing equipment includes a one-step automatic injection blow molding machine, which combines preform injection molding and bottle body blow molding. The injection molding and blow molding are carried out on the same worktable, so the injection molding and blow molding molds are installed in a On the working table, the turret drives three sets of the same mandrels to transfer to three different stations for injection molding, blow molding and demoulding. The distance between the three stations is 120 degrees, and the turret is driven by the main shaft.

Problems solved by technology

Chinese invention patent 201120190591.5 (authorized announcement number is CN202129985U) discloses a servo motor-driven transposition device for plastic injection blow molding machines. On the other hand, through the gear transmission, the main shaft is driven to rotate. In this way, through the gear transmission, energy is wasted, and if the gear machining accuracy is low or the gear is worn for a long time, the angular accuracy of the main shaft rotation will be reduced.

And because the servo motor is installed on the side of the main shaft, the space volume is increased, and there are many internal parts, which affect the ventilation and poor heat dissipation efficiency
