Bottle making machine and its turntable driving device

Abstract

The invention discloses a rotary table driving device for a bottle making machine. The rotary table driving device comprises a part A rotary table driving device arranged on a bedplate, and / or a part B rotary table driving device arranged on the bedplate. The part A rotary table driving device comprises a bearing pedestal, a rotary table hollow shaft and a rack wheel spindle which are arranged above the bedplate, as well as a mounting seat mounted below the bedplate, wherein a first rotary platform is arranged in the mounting seat and driven by a first servo motor, and a first speed reducer is arranged below the mounting seat; the lower end of the rotary table hollow shaft is mounted on the first rotary platform; the lower end of the rack wheel spindle is mounted on an output shaft of the first speed reducer; the bearing pedestal comprises a support cylinder and an outer cylinder sleeve; a coolant passage is arranged on the outer edge of the support cylinder which is matched with the outer cylinder sleeve, and is distributed from bottom to top along a helical line; a lower connecting port and an upper connecting port of the coolant passage are respectively arranged at the lower part and the upper part of the outer cylinder sleeve. The rotary table driving device has the advantages of simplicity in structure, high convenience in operation, and higher stability and precision. The invention further provides the bottle making machine employing the rotary table driving device.

Description

technical field [0001] This application relates to the technical field of glass bottle preparation, in particular to a turntable drive device mainly used in bottle making machines. In the bottle making system, the turntable drive device includes A part turntable drive device and / or B part turntable drive device , mainly used to install and drive the large gear of part A and the turntable of part A and / or install and drive the large gear of part B and the turntable of part B. [0002] In addition, the present application also relates to a bottle making machine using the above-mentioned turntable driving device. Background technique [0003] Existing vertical bottle-making machines that use glass tubes to make glass bottles, such as vertical bottle-making machines for producing vials, generally include a fuselage, A and B parts installed on the fuselage, and other corresponding parts. part. For example, the Chinese invention patent application whose application publication n...

Problems solved by technology

[0004] In practice, the applicant's researchers found that there are at least the following problems: 1). Due to the needs of the production process, the height of the turntable and the corresponding parts of part A is higher than that of part B, so the platen of the fuselage needs to be There is a vertical bearing seat (called the supporting sleeve in CN 103539335 A) for installing the A-part turntable and the A-part gearwheel, etc., and because the whole bottle-making machine is in a relatively high temperature environment, therefore The strength or rigidity of the vertical bearing seat needs to be additionally strengthened, otherwise the vertical bearing seat is easy to deform under the conditions of high temperature and vibration, which will affect the accuracy of the glass bottle; 2). Due to the needs of the production process, the turntable and The height of the corresponding parts needs to be adjusted, and the transmission structure provided in the aforementioned technical solution is complicated, and the structure of the lifting mechanism is complicated
