Description

Technical Field

[0001] A rotary table mechanism for a disc bottle-making machine belongs to the field of glass machinery technology. Background Technology

[0002] Row-type bottle making machines are common mechanical equipment used to manufacture glass bottles. In traditional row-type bottle making machines, the ratio of the initial mold to the final mold is 1:1, meaning one initial mold corresponds to one final mold. To improve bottle making efficiency, an improved row-type bottle making machine has emerged in the prior art: the disc-type bottle making machine, as described in Chinese Utility Model Patent Application No. 201822051375.7, filed on December 7, 2018, entitled "A Frame-Type Disc-Type Bottle Making Machine." The disc-type bottle making machine, with its row-type structure and rotary table mechanism, allows one initial mold to correspond to at least two final molds, enabling the two final molds to work alternately.

[0003] In a disc-type bottle-making machine, since the two forming molds rotate and work alternately, the turntable distributes the air passages on the two forming sides while rotating, enabling the pneumatic components (such as the positive blowing mechanism) in the two forming molds to operate. This is a crucial step in ensuring the normal operation of the disc-type bottle-making machine. In existing technologies, slip ring structures are commonly used, such as pneumatic-electric slip rings (e.g., the technical solution described in Chinese Utility Model Patent Application No. 201621389049.1, filed on December 16, 2016, entitled "A Stem Glass Buttoning Machine"), or oil-pneumatic slip rings (e.g., the technical solution described in Chinese Utility Model Patent Application No. 202023281109.7, filed on December 30, 2010, entitled "A Glass Bottle-Making Machine with Synchronous Double Positive Blowing").

[0004] In practical use, it has been found that regardless of whether pneumatic or oil-pneumatic slip rings are used, there is a problem of short lifespan when the air distribution is achieved through the slip ring structure. Therefore, designing a more reliable technical solution to increase the service life has become an urgent problem to be solved in this field. Utility Model Content

A fixed shaft 1 is erected on the upper surface of the fixed base 20, passing through the center of the turntable.

[0025] Two air supply chambers are provided at the center of the fixed shaft 1: an upper air supply chamber 3 and a lower air supply chamber 19. The upper air supply chamber 3 extends downward from the top surface of the fixed shaft 1 along its axial direction, while the lower air supply chamber 19 extends upward from the top surface of the fixed shaft 1 along its axial direction. An upper air supply channel 25 is provided at the bottom of the upper air supply chamber 3, with multiple channels radially branched. The outer ends of the upper air supply channels 25 extend to the outer wall of the fixed shaft 1. A lower air supply pipe 21 is connected to the bottom of the lower air supply chamber 19, and a similar air supply pipe (not shown in the figure) is connected to the upper air supply chamber 3.

A set (two) of solenoid valves 12 are arranged in the space formed between the upper plate 10 and the lower plate 13. An air pipe 27 extends from each of the two air outlets, connecting to the air inlets of the two solenoid valves 12 respectively. By controlling the solenoid valves 12, air distribution is achieved, such as the process gas outlet 11 located on the surface of the upper plate 10 and connected to the outlet of the solenoid valve 12 via a pipe. Multiple sets of solenoid valves 12 can also be configured as needed, used for distributing process gas and gas for functional mechanisms.

The rotary wire 7 passes through the upper plate 10 and is connected to the terminals of the two solenoid valves 12 respectively.

[0032] In the rotary bottle-making machine, the use of electric slip rings can increase the system's redundancy. For example, the slip ring system can be configured with 15 fixed lines and 15 rotary lines, including two 10A lines for lubrication pumps and the remaining 5A lines for solenoid valve signals and as backups. This can supply power to eight functional mechanisms or process gas components, with one common line and four backup lines. If a line experiences a short circuit, it can be replaced with a backup line without replacing the entire slip ring system.

[0033] The specific working process and working principle are as follows:

[0034] External air supply is delivered into the upper air supply chamber 3 and the lower air supply chamber 19 via pipelines. One of the two air supply streams is delivered to one of the air pipes 27 via the upper air supply channel 25 and the upper air distribution ring 24, while the other is delivered to the other air pipe 27 via the lower air supply channel 23 and the lower air distribution ring 22. The two air pipes 27 respectively deliver air to the inlet ends of two solenoid valves 12. External control signals are sent to the two solenoid valves 12 via the fixed line 2, the slip ring 5, and the rotary line 7. According to process requirements, when air supply distribution is required, the control signal is sent to the control end of the corresponding solenoid valve 12, and the corresponding solenoid valve 12 actuates to realize the air supply distribution.
