AI Technical Summary
In existing tire production equipment, the tread scribe system is prone to blockage, resulting in unclear scribe lines, affecting tread identification and production quality.
The push-up all-steel pressure-out line tread marking system is adopted. By installing the color material barrel fixing frame and thrust cylinder on the tread conveyor belt, the compressed air is used to drive the thrust cylinder piston to push the color material into the copper tube to ensure that the color material is evenly attached to the tread.
Maintenance is achieved during the production process, avoiding copper mouth blockage, and ensuring the clarity of tread marking and production continuity.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of tire production equipment, and particularly to a boosting type all-steel extruder tread scribing system. Background Art
[0002] As is well known, the tread extruder is the mainstream type of current tire semi-finished product production equipment. In order to distinguish different patterns of various tires, a method of attaching colorant to the tread is generally used for scribing. The original scribing method used a large colorant container with an air pipe adapter installed at the bottom. The colorant in the container was transported by its own weight through the air pipe for transportation to the scribing copper nozzle, and the copper nozzle attached the colorant to the tread. This set of scribing system often causes blockage due to colorant precipitation and small self-weight pressure, resulting in unscribed treads, affecting the identification of various specifications of treads in the subsequent processes, and extremely likely to produce batches of unqualified treads. Summary of the Invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a boosting type all-steel extruder tread scribing system to solve the problems of unclear scribing and blockage of the scribing copper nozzle.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a boosting type all-steel extruder tread scribing system is provided with a tread conveyor belt. Its characteristics are that a colorant bucket fixing frame is installed above the tread conveyor belt, a colorant bucket is fixed on the colorant bucket fixing frame, a colorant copper pipe communicating with the inner cavity of the colorant bucket is installed at the bottom of the colorant bucket, the end of the colorant copper pipe is installed with a scribing roller through a rotating shaft, a thrust cylinder fixing frame is fixed at the upper end of the colorant bucket fixing frame, the cylinder body of the thrust cylinder is fixed on the thrust cylinder fixing frame, the thrust cylinder piston of the thrust cylinder is located in the colorant bucket, the thrust cylinder piston is slidably matched with the inner cavity wall of the colorant bucket, and an air inlet air pipe and an air outlet air pipe are arranged on the cylinder body of the thrust cylinder.
[0005] The beneficial effect of the utility model is that maintenance-free can be realized during the production process. The colorant is pressurized by the boosting cylinder, and the pressure of the boosting cylinder can be adjusted according to the amount of the colorant. The pressurized colorant can enter the scribing roller through the copper pipe that is not easy to be blocked, and the colorant is evenly attached to the tread by the scribing roller. Brief Description of the Drawings
[0006] The following further illustrates the utility model with reference to the drawings and embodiments.

Detailed implementation mode
[0009] In the figure, the utility model is provided with a tread conveyor belt 12. The feature is that a colorant bucket fixing bracket 8 is installed above the tread conveyor belt 12. The colorant bucket 3 is fixed on the colorant bucket fixing bracket 8. A colorant copper pipe 4 communicating with the inner cavity of the colorant bucket 3 is installed at the bottom of the colorant bucket 3. The end of the colorant copper pipe 4 is installed with a scribing roller 10 through a rotating shaft. The upper end of the colorant bucket fixing bracket 8 is fixed with a thrust cylinder fixing bracket 7. The cylinder body of the thrust cylinder 5 is fixed on the thrust cylinder fixing bracket 7. The thrust cylinder piston 6 of the thrust cylinder 5 is located in the colorant bucket 3. The thrust cylinder piston 6 is in sliding fit with the inner cavity wall of the colorant bucket 3. An air inlet duct 1 and an air outlet duct 2 are arranged on the cylinder body of the thrust cylinder 5.
[0010] During production, the colorant 9 for tread scribing is added to the colorant bucket 3. When the tread 11 extruded from the die plate of the extruder is conveyed to the tread scribing station by the tread conveyor belt 12, 0.8 Mpa compressed air is introduced into the air inlet duct 1. The compressed air enters the thrust cylinder 5 to drive the cylinder rod of the thrust cylinder to act. The thrust cylinder piston 6 at the end of the thrust cylinder 5 will pressurize the colorant 9 in the colorant bucket 3, and then push the colorant 9 into the colorant copper pipe 4. The colorant entering the colorant copper pipe 4 enters the scribing roller 10 under the push of the pressure. During normal production, the tread conveyor belt 12 drives the tread 11 to be transmitted. When the tread 11 is transmitted, it drives the scribing roller 10 pressed on the tread 11 to rotate. As the scribing roller 10 rotates, the pressure colorant extruded by the thrust cylinder 5 is drawn on the tread 11, completing the task of scribing the semi-finished tread.
