Description

Technical Field

[0001] The invention belongs to the technical field of tire production equipment and production process, and in particular relates to a production device for fixed-length and oblique-cutting silent sponge tires, and a production method for silent sponge tires based on the production device. Background Art

[0002] Silent sponge tires use sponge to stick inside the car tire. The porous characteristics of the silent sponge can absorb the resonant noise generated by the tire and the road, which can significantly improve driving comfort.

[0003] The existing silent sponge is specifically made by applying glue on the inner wall of the tire and then sticking the strip of sponge on it. Since there is a certain stress between the sponge and the glue, under extreme conditions of high-speed driving, the sponge will cause the sponge to be glued or even fall off due to factors such as internal wind resistance and stress, thereby affecting driving. Therefore, the applicant applied for an application number of 202223220436.0, named: A utility model patent technology for a silent sponge tire. In this technical scheme, in order to avoid the risk of falling off easily caused by the ordinary vertical structure of the end of the sponge in the prior art under high wind resistance, the sponge is designed to include a bevel cut design at the port and a "V" shape design after the port of a one-piece sponge strip is spliced, a bevel overlap design and the sponge strip port is fixedly bonded with an adhesive or a gap-shaped non-bonded design, a bevel cut design at the port and a "V" shape design after the port of a one-piece sponge strip is spliced, etc.; the above structure can effectively avoid the risk of falling off caused by high wind resistance. Based on the needs of industrialized, large-scale, and automated production, it is necessary to provide a cutting device that can realize the above-mentioned sponge port structure. For example, the application number is 202220293734.3, and the name is a cutting mechanism for a silent sponge. Specifically, the upper pressure plate is driven by a cylinder to move upward. When the pressure plate moves upward, the connecting tubes on both sides of the pressure plate slide on the outside of the pillar to limit the position of the pressure plate. The pressure plate moves upward and cooperates with the upper top plate to jointly pressurize and position the silent sponge, thereby avoiding the displacement of the silent sponge during the cutting process. It can be seen that the cutting device of the above-mentioned silent sponge is an ordinary vertical cross-section cutting, and there is no mature and efficient technical solution to realize the cutting device of the above-mentioned anti-falling silent sponge end structure. Based on this, the technical solution proposes a production device that can cut silent sponge tires in a fixed length and obliquely, which is of great significance for realizing the industrialized, large-scale, and automated production of anti-falling silent sponges.

[0061] As Figures 9-10 shown, a method for producing a sound-absorbing sponge tire with fixed length and oblique cutting uses the above-mentioned device for producing a sound-absorbing sponge tire with fixed length and oblique cutting, and includes the following steps:

[0062] S1. Obtain the tire barcode number and corresponding size information and input them into the computer control system, and perform laser cleaning on the inner wall of the tire. This step is approximately the same as step one in the patent technology of "202210890377.3 A continuous multi-segment silent sponge tire production equipment and its production method" applied by the applicant;

[0065] The cutting part below the first carrier 605 is driven by the first telescopic structure to move horizontally above the cutting and adjusting conveyor mechanism 7 to perform a first cut on the sound-absorbing sponge 8; after the needle punching cylinder structure 706 cooperates with the first lead screw structure and the first sliding structure to push forward and the front end is continuously transported by the sponge transport track, the distance generated by the second cut after a fixed length interval is used as the fixed length interval for cutting.

[0066] S3. The sound-absorbing sponge 8 is transported on the C track and protrudes. Protruding refers to the port side of the cut sound-absorbing sponge 8. The C track is shown in the technical content of the C track in CN202210890377.3 - A continuous multi-section sound-absorbing sponge tire production device and its production method.
