Description

TECHNICAL FIELD

[0001] The present application relates to the field of tire vulcanization equipment, in particular to an automatic adjusting system of a green tire holder of a full-steel vulcanization machine. BACKGROUND

[0002] It is known that the full-steel hot plate type tire vulcanization machine is the mainstream type of the current tire vulcanization equipment, the tire blank is conveyed by an automatic loop, the tire blank is stored on the green tire holder in front of the machine table, and then the tire is grabbed and mounted by a tire mounting mechanical arm. Since there are many production specifications and the diameters of the tire blanks are different, the opening degree of the green tire holder needs to be manually adjusted by a manual lever according to the size of the diameter of the tire blank. The labor intensity of manual adjustment is large, and errors are prone to occur during manual adjustment, thereby causing quality risks. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, the present application provides an automatic adjusting system of a green tire holder of a full-steel vulcanization machine, which can automatically adjust the opening degree of the green tire holder.

[0004] The technical scheme adopted by the present application to solve the technical problem is: an automatic adjusting system of a green tire holder of a full-steel vulcanization machine, which is provided with a green tire holder guard plate, characterized in that an adjusting disc is mounted in the middle of the green tire holder guard plate through a rotating shaft, four guide rails are symmetrically fixed on the outer side of the green tire holder guard plate, one green tire holder claw is slidably mounted on each guide rail, each green tire holder claw is hingedly connected to the adjusting disc through a connecting rod, a servo motor is mounted on the green tire holder guard plate, the servo motor is controlled by a PLC controller, the output shaft of the servo motor is connected to one end of a worm gear and a worm, and the other end of the worm is threadedly connected to one green tire holder claw.

[0005] The present application has the beneficial effects that the opening degree of the green tire holder can be adjusted by the automatic control system driving the servo motor according to different production specifications, the labor intensity of manual adjustment can be reduced, and the quality risks caused by errors during manual adjustment can be eliminated. BRIEF DESCRIPTION OF DRAWINGS

[0006] The present application will be further described below in combination with the drawings and embodiments.

[0007] Figure 1 The structural schematic diagram of the present application.

[0008] In the drawings, 1 is a green tire holder claw, 2 is a connecting rod, 3 is an adjusting disc, 4 is a worm, 5 is a servo motor, 6 is a guide rail, and 7 is a green tire holder guard plate. DETAILED DESCRIPTION

[0009] In the figure, the green tire protector 7 is provided with an adjusting disc 3 in the middle and installed through a rotating shaft, four guide rails 6 are symmetrically fixed on the green tire protector 7 outside the adjusting disc 3, one green tire protector claw 1 is installed on each guide rail 6 in sliding fit, each green tire protector claw 1 is hingedly connected with the adjusting disc 3 through a connecting rod 2, a servo motor 5 is installed on the green tire protector 7, the servo motor 5 is controlled by a PLC controller, the output shaft of the servo motor 5 is connected with one end of a worm and gear 4, and the other end of the worm and gear 4 is threadedly connected with one green tire protector claw 1.

[0010] When the present application is used, the size corresponding to each specification is first archived in the database of the MES, the archived database is bound with the curing specification saved in the MES, the association between the curing specification and the corresponding size is realized, when the curing machine needs to change the specification, the machine will automatically call the specification information consistent with the production specification in the database, the tire blank size information of the corresponding specification is transmitted to the servo driver by the PLC controller of the curing machine, the data is transmitted to the servo motor 5 by the servo driver, the servo motor 5 drives the worm 4 to rotate after receiving the information, the worm 4 drives the green tire protector claw 1 to move along the guide rail 6 when rotating, the green tire protector claw 1 synchronously links and adjusts the other three green tire protector claws 1 through the connecting rod 2 hingedly connected on the adjusting disc 3, and drives the adjusting disc 3 to move in a circle, thus, the automatic adjusting process of the opening size of the green tire protector claw 1 of the curing machine is completed.
