Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, in particular to a tire embryo stretching and shaping device. Background Art

[0002] As we all know, when vulcanizing tire embryos, first place the embryos on the tire storage trolley, which is fixed in front of the front manipulator of the vulcanizer in advance. In the automatic state and when there is a tire embryo on the tire storage trolley, the program controls the vulcanizer manipulator to descend along the lifting guide rail to the embryo mouth position, and controls the vulcanizer mechanical claw to grasp the embryo at the mouth position, and then the vulcanizer manipulator rises, and the vulcanizer mechanical claw sends the grasped embryo into the vulcanizer mold under the action of the manipulator rotating device. Tire embryos made of low Mooney materials are prone to deformation. At the same time, the storage time and ambient temperature of the tire embryos also have a great impact on the fluidity of the materials. Especially in summer when the temperature is high, the deformation of the tire embryo is particularly prominent. The deformation of the tire embryo causes the finished tire to have problems of insufficient glue and excess glue at the mouth. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a tire embryo stretching and shaping device, which uses a tire storage trolley and a vulcanizer manipulator to stretch and shape the tire embryo before it enters the vulcanizer, thereby ensuring the original shape of the tire embryo during production to the greatest extent.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a tire embryo stretching and shaping device is provided with a vulcanizer manipulator column frame, a lifting guide rail is fixed on the vulcanizer manipulator column frame, a sliding block is installed on the lifting guide rail, a vulcanizer manipulator is fixed on the block, and a vulcanizer manipulator claw is fixed on the vulcanizer manipulator via a manipulator rotating device. The utility model is characterized in that a tire storage trolley is placed below the vulcanizer manipulator, a tire conveyor belt is installed on the tire storage trolley via parallel rollers, a tire storage mechanical claw lifting tray is installed at the end of the tire storage trolley, a tire storage mechanical claw with the same structure as the vulcanizer mechanical claw is installed on the tire storage mechanical claw lifting tray, a photoelectric sensor is installed on the vulcanizer manipulator, the photoelectric sensor is connected to the signal input end of the PLC controller, and the PLC controller controls the vulcanizer mechanical claw, the vulcanizer manipulator, the manipulator rotating device, the tire storage mechanical claw lifting tray, and the tire storage mechanical claw action.

[0005] The beneficial effect of the utility model is that the green tire is stretched and shaped with the cooperation of the tire storage trolley and the vulcanizer manipulator, especially for tires made of low Mooney materials and under high ambient temperature, where the tires are prone to serious deformation. The tires are stretched and shaped with the cooperation of the vulcanizer manipulator and the tire storage device opening claws, which can effectively prevent the tires from deforming before entering the vulcanizer mold, reduce the situation of lack of glue and excess glue at the mouth of the finished tire, and improve the quality of the finished tire.

DETAILED DESCRIPTION

[0009] In the figure, the utility model is provided with a vulcanizer manipulator column frame 5, a lifting guide rail 7 is fixed on the vulcanizer manipulator column frame 5, a sliding block 8 is installed on the lifting guide rail 7, a vulcanizer manipulator 4 is fixed on the slider 8, a vulcanizer manipulator claw 2 is fixed on the vulcanizer manipulator 4 via a manipulator rotating device 6, a tire storage trolley 3 is placed below the vulcanizer manipulator 4, a tire conveyor belt 9 is installed on the tire storage trolley 3 via parallel rollers, a tire storage mechanical claw lifting tray 10 is installed at the end of the tire storage trolley 3, a tire storage mechanical claw lifting tray 10 is installed with a tire storage mechanical claw 1 with the same structure as the vulcanizer mechanical claw 2, a photoelectric sensor is installed on the vulcanizer manipulator 4, and the photoelectric sensor is connected to the signal input end of the PLC controller. The PLC controller controls the vulcanizer mechanical claw 2, the vulcanizer manipulator 4, the manipulator rotating device 6, the tire storage mechanical claw lifting tray 10, and the tire storage mechanical claw 1.

[0010] According to the specifications of the tire blank, the descending position and stretching time of the vulcanizer manipulator 4 are set in advance on the operation interface. When the vulcanizer manipulator 4 is triggered to grab the tire blank, the vulcanizer manipulator 4 begins to descend along the lifting guide rail 7, and the tire storage mechanical claw hand lifting tray 10 rises at the same time. When the vulcanizer manipulator 4 descends to the point where the photoelectric sensor senses the upper mouth of the tire blank, the photoelectric sensor transmits a signal to the PLC controller, and the PLC controller controls the vulcanizer manipulator 4 to stop, and controls the claws of the vulcanizer mechanical claw hand 2 to open, and at the same time gives the tire storage machine a signal. The mechanical gripper 1 sends a signal, so that the upper end of the tire embryo is caught by the claw of the vulcanizer mechanical gripper 2, and the lower end of the tire embryo is caught by the claw of the tire storage device mechanical gripper 1. After the claw of the tire storage device mechanical gripper 1 opens, the signal is fed back to the PLC controller, so that the vulcanizer robot 4 rises to the set stretching height. At this time, the tire embryo begins to stretch and shape. When the set stretching time is reached, the PLC controller controls the claw of the tire storage device mechanical gripper 1 to release the lower end of the tire embryo. Then the vulcanizer robot 4 completely grabs the tire embryo and sends it into the vulcanizer mold for vulcanization.
