Direct-drive bottle making machine and direct-drive bottle making method
Technical Field
The invention belongs to the technical field of bottle making machines, and particularly relates to a direct-drive bottle making machine and a direct-drive bottle making method.
Background
When the bottle making machine works, the bottle making A part and the bottle making B part respectively revolve around the axes of the chuck plates, and simultaneously, the bottle making A part and the bottle making B part respectively rotate around the axes of the chucks. Under the revolution of the chuck plate at the part A of the bottle making and the autorotation of the chuck, the part A of the bottle making realizes the processing of the material pipe to form a semi-finished bottle; and under the revolution of the chuck plate of the bottle-making part B and the self rotation of the chuck, the bottle-making part B inputs the bottle-making part A into a semi-finished bottle body of the chuck of the bottle-making part B to process the semi-finished bottle body to form a finished bottle.
Because some processing stations of the part A and the part B of the bottle making, such as a bottle making opening station, a bottle receiving station, a flat bottom station, a bottle unloading station and an edge cutting station of a pre-encapsulation bottle making machine, all need the clamping heads to stop rotating to complete corresponding processing procedures. Therefore, the conventional structure for controlling the rotation of the chucks in the B-part or the a-part of the bottle-making includes not only a rotation driving mechanism for driving the chucks to rotate but also a clutch control mechanism for controlling the chucks to stop rotating. The clutch control mechanism is a lower clutch matched with the upper clutch, a linear moving assembly for controlling the lower clutch to move up and down linearly, and a reset mechanism connected with the lower clutch and used for controlling the lower clutch to move to a position in contact with the upper clutch. When the structure is used for driving the chucks of the part B or the part A to rotate, the motor drives the upper clutch to rotate, the upper clutch is in close contact with the lower clutch, the upper clutch drives the lower clutch to rotate, and therefore the lower clutch drives the bottle dropping pipe to rotate through the outer sliding sleeve; when the clutch control mechanism is used, the linear moving assembly drives the lower clutch to move downwards, so that the upper clutch is separated from the lower clutch, and the bottle dropping pipe stops rotating.
The structure for controlling the autorotation of the part A or the part B of the bottle making in the prior art is adopted, and the following defects exist in the practical application:
one is the complex structure. In the structure of the autorotation of the A part or the B part of the existing bottle-making, the autorotation driving mechanism for driving the autorotation of the chuck of the B part is included, and the clutch control mechanism for controlling the chuck to stop autorotation needs to be additionally arranged, so that the autorotation control of the bottle-making chuck can be realized only by matching two parts of structures as a whole, the autorotation structure of the existing bottle-making chuck is complex in arrangement, high in precision required for machining parts, and difficult to produce and manufacture.
Secondly, the positioning accuracy is low. Because the existing chuck control structure is set more complicated, the control of rotation and braking can be realized only by the mutual matching of all parts, all mechanical parts are easy to wear, particularly, the wear between the upper clutch and the lower clutch is large, the gap between the upper clutch and the lower clutch is gradually increased after the parts are stressed in a long-term and ceaseless operation, the accuracy of the rotating positions of the chuck plates of the A part and the B part of the bottle making machine is greatly influenced, the production quality of bottle bodies processed by the bottle making machine is influenced, the increase of unqualified products is caused, and the production efficiency of enterprises is reduced.
And thirdly, it is inconvenient to control. The structure of the existing bottle-making part B is complex, the positioning accuracy is low, the rotating speed, the rotating angle and the start and stop of the rotation of the chuck of the bottle-making part B are not easy to control, so that the components of the indexing and station setting of the chuck of the bottle-making part B, the bottle-making bottom mechanism, the chuck lifting opening and closing mechanism, the chuck clutch control mechanism, the bottle falling mechanism and the like are not adjustable, the requirement on the machining accuracy of machine parts is high, and the difficulty in assembling and debugging of a bottle-making machine is large.
Fourthly, special bottles with complex structures cannot be produced. Due to poor adjustability among all mechanical components of the existing bottle making machine, when the chuck is matched with a corresponding processing mechanism to make special bottles, bottles with complex structures or higher quality requirements, especially special bottles with threads, special-shaped bottles or bottles with strict requirements on product quality, the existing bottle making machine is difficult to meet the production requirements, limits the types of the processed bottles and has limited application range.
Fifthly, noise pollution is easily caused. The upper clutch and the lower clutch in the existing autorotation structure have larger stress running-in the operation process, can generate larger noise and easily cause noise pollution in a workshop.
And sixthly, energy waste is easily caused. The kinetic energy of the motor is not directly converted into kinetic energy for driving the chuck to rotate in the rotation structures of the A part and the B part of the existing bottle making, multi-stage transmission is needed, and when the chuck is controlled to stop rotating through the clutch control mechanism, the motor continuously transmits the power to the upper clutch, so that more electric energy and maintenance cost are obviously consumed, and the operation cost of an enterprise is greatly increased.
And seventhly, faults are easy to generate, and maintenance is inconvenient. In a production workshop, production equipment is in a 24-hour continuous running state for most of time, frequent inspection and maintenance are required, and the clearance and the precision between an upper clutch and a lower clutch in a chuck self-rotating structure are required to be adjusted after the production equipment is used for half a year or one period, so that the maintenance cost is greatly increased; when the rotational positioning precision of the chuck can not meet the requirement, the clutch control mechanism and the autorotation driving mechanism must be replaced, the service life of the machine parts is short, and the operation and production cost of enterprises is greatly increased.
