Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a beveling mechanism for a silent noise reduction material. 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] According to a silent sponge tire disclosed in Chinese patent number CN219029032U, it includes a tire body and a sponge strip, the sponge strip is attached to the inner wall of the tire body, the sponge strip is designed in a long strip shape, and is designed with 1-10 sections; the end of the sponge strip is designed in an oblique cut shape, and the end of the one-stage sponge strip is in a 'V' shape after splicing, the sponge strip is designed in an oblique overlap shape, and the end of the sponge strip is fixedly bonded by an adhesive or is designed in a gap shape without bonding. The utility model reduces the damage caused by wind resistance when the tire is running at high speed by cutting the head and tail of the sponge strip into a slope shape during the production process. After the sponge strip is attached to the inner wall of the tire body, the gap between the head and tail forms a V-shaped structure or directly overlaps each other to form a complete sponge strip; and the multi-section slope design can also well avoid the interference between the head and tail sections, thereby increasing the structural strength of the sponge itself, reducing the influence of wind resistance and stress, and ensuring that the tire does not fall off when running at high speed.

[0004] According to a cutting mechanism of a silent sponge disclosed in Chinese patent number CN218476762U, the cutting mechanism includes a body and a silent sponge. The silent sponge is placed on the top of the body, and a pressurizing mechanism is arranged at one end of the body; the pressurizing mechanism includes: a top plate, a pressurizing plate, pillars, a connecting tube, a bottom plate, and a cylinder; wherein a top plate is fixedly installed at one end of the body, pillars are fixedly installed at both ends below the top plate, a bottom plate is fixedly installed at the ends of the two pillars, a cylinder is fixedly installed in the middle of the bottom plate, and a pressurizing plate is fixedly installed at the top of the cylinder. In the cutting mechanism of this silent sponge, when the cylinder works, it drives the upper pressurizing plate to move upward. When the pressurizing plate moves upward, the connecting tubes on both sides of the pressurizing plate slide on the outside of the pillars to limit the position of the pressurizing plate. The upward movement of the pressurizing plate cooperates with the upper top plate to pressurize and position the silent sponge together, thereby effectively avoiding displacement of the silent sponge during the cutting process.

[0005] The above-mentioned comparative documents and prior art have the following technical problems: the cutting device of the silent sponge is a common vertical cross-section cutting, the cutting head and method are single, and the adaptability is poor. Utility Model Content

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0024] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0026] Reference Figure 1-5A beveling mechanism for a silent noise reduction material comprises a support bracket 1 and a silent sponge 15. The support bracket 1 is provided with two groups. A parallel slide rail 3 is provided on the side of the support bracket 1. A load-bearing support plate 2 is provided for sliding between adjacent parallel slide rails 3. A tool holder body 6 is provided on the top surface of the load-bearing support plate 2. A rotating motor 5 is provided on the bottom surface of the load-bearing support plate 2. The output shaft of the rotating motor 5 is connected to the bottom surface of the tool holder body 6. A limiting knife seat 7 is connected to the top of the tool holder body 6. A cutting knife 8 is connected to the end of the limiting knife seat 7. The type of the cutting knife 8 is one or more of a disc knife, an electric heating knife, an electric heating wire, and a plane knife. A mounting bracket 9 is bolted on the side of the support bracket 1. The mounting bracket 9 is provided on the bottom surface of the support bracket 1. A silent sponge 15 is snap-fitted onto the surface of the seat 9. The load-bearing bracket supports the tool holder body 6 and then connects the cutting knife 8 to cut the silent sponge 15. By setting the cutting knife 8 to a variety of knife-type structures such as a disc knife, an electric heating knife, an electric heating wire, and a flat knife, the silent sponge 15 can be cut according to different types of cutting knives 8. With the cooperation of the rotating motor 5 and the driving assembly 4, different cutting methods such as oblique, vertical, and fixed-length cutting can be realized for the silent sponge 15 on the surface of the mounting support 9. The cutting knife 8 and the cutting method are highly adaptable, which is convenient for adapting to the cutting requirements of various silent sponges 15 and is convenient for subsequent tire processing and splicing.

[0027] In order to increase the clamping and pressing of the whole device on the silent sponge 15 and prevent the silent sponge 15 from shaking, the side of the mounting support 9 is bolted to the side of the support bracket 1, and a positioning pressure plate 10 is provided on the side of the mounting support 9, and the positioning pressure plate 10 is connected to the surface of the mounting support 9 with screws. A silent sponge 15 is engaged between the side of the mounting support 9 and the side of the positioning pressure plate 10. The silent sponge 15 is limited by the gap between the positioning pressure plate 10 and the mounting support 9 to prevent the silent sponge 15 from falling and maintain a fixed height position. In order to facilitate the anti-slip treatment of the silent sponge 15, a mounting support 9 is provided with a thorn base 11 bolted inside, and a limiting thorn needle 12 is provided on the surface of the thorn needle base 11, and the limiting thorn needle 12 passes through the surface of the silent sponge 15 along the inclined opening groove 14. The limiting thorn needle 12 connected to the thorn needle base 11 punctures the silent sponge 15, limits the silent sponge 15, prevents the silent sponge 15 from sliding, maintains the stability of the silent sponge 15 during cutting, prevents sliding, thereby reducing cutting errors and improving cutting accuracy.

[0028] In order to facilitate the cutting and adaptation of the silent sponge 15 between the U-shaped bracket and the cutting knife 8, a straight opening groove 13 is provided at the same central position on the surface of the positioning pressure plate 10 and the mounting support 9, and the straight opening groove 13 penetrates the bottom surface of the positioning pressure plate 10 and the mounting support 9. Bevel opening grooves 14 are symmetrically distributed on both sides of the straight opening groove 13. When the cutting knife 8 moves up and down for cutting, the silent sponge 15 can be cut after penetrating along the straight opening groove 13 and the bevel snap groove. Since the bevel opening groove 14 penetrates the limiting needle 12, the straight opening groove 13 is generally used when cutting. If the bevel opening groove 14 is used for cutting, the limiting needle 12 can be penetrated through the straight opening groove 13 to limit the silent sponge 15.

When multiple sets of tool holder bodies 6 are provided on the surface of the load-bearing support plate 2, adjacent tool holder bodies 6 are distributed circumferentially, and the tool holder bodies 6 correspond to the cutting knife 8 groups one by one. A driving component 4 is bolted to the inner side of the support bracket 1 away from the surface of the mounting support 9, and the movable end of the driving component 4 is connected to the top end of the load-bearing support plate 2. The driving component 4 drives the entire load-bearing support plate 2 and its surface structure to move up and down along the surface of the parallel slide rail 3, which is convenient for driving the cutting knife 8 to cut the silent sponge 15 in the vertical direction. Specific embodiment 2:
