Description

Technical Field

[0002] Tire noise is the noise generated by the interaction between the tires of a moving vehicle and the road surface, the interaction between the tires and the air, and the deformation of the tires. It is one of the two main sources of automobile noise. When the car speed reaches a certain level, tire noise may become the main source of noise. Therefore, it is necessary to stick silent cotton on the inner wall of the tire to reduce the tire noise when the car is driving.

[0004] Existing silent cotton is usually pasted on the tire by squeezing the silent cotton onto the inner wall of the tire with an extrusion roller. It is found during use and observation that the inner wall of the tire is attached with dust and other impurities. These impurities will reduce the contact area between the silent cotton and the inner wall of the tire, reduce the adhesion between the silent cotton and the tire, and cause the silent cotton to easily fall off the tire surface, which will reduce the quality of the equipment for pasting the silent cotton on the tire.

After the tire is placed on the top of the tray 103, the first fixing rod 104 is slid by starting the electric push rod 120, so that the first fixing rod 104 squeezes the outer wall of the tire and fixes the tire. Then the starting device drives the electric slide rail 105 to move with the support plate 106. When the support plate 106 reaches a suitable height, the electric slide rail 105 stops moving. Then the drive motor 102 and the linear motor 109 are started. After the drive motor 102 is started, the tray 103 drives the tire to rotate together, and the linear motor 109 is started to push the first connecting plate 110 to approach the tire. When the connecting plate 110 moves, it will move with the second connecting plate 111. When the second connecting plate 111 moves, it will bring the first roller 112 closer to the tire. When the first roller 112 contacts the inner wall of the tire, the first roller 112 will be squeezed by the inner wall of the tire and the first spring 114 will be bent under pressure. When the first spring 114 bends, the angle of the first roller 112 will also change. As the second connecting plate 111 moves, the first roller 112 will gradually adapt to and adhere to the inner wall of the tire. After the first roller 112 contacts the inner wall of the tire, it will rotate under the action of friction. Then, the air pipe 115 is connected to an air pump to make the air pump The tube 115 draws air into the first roller 112, and the air passes through the fixing seat 119 and flows into the first roller 112. Then, when the airflow reaches the first connecting tube 113, it passes through the second circular hole 117, and a negative pressure state is formed around the first circular hole 116, so that the surrounding air passes through the first circular hole 116 and enters the first roller 112. When the air flows, the impurities attached to the inner wall of the tire are diffused and enter the first circular hole 116 together with the airflow, so that the device pre-cleans the inner wall of the tire. After the cleaning work is completed, the linear motor 109 can be moved in the reverse direction to make the second connecting plate 111 away from the tire, and then the extrusion assembly 1 is started. 07 makes the squeezing component 107 approach the tire with the silent cotton on the surface of the second fixing rod 118. When the squeezing component 107 contacts the tire, it squeezes the inner wall of the tire and adheres the silent cotton to the inner wall of the tire. After the silent cotton is adhered, the cutting component 108 can be started to cut the excess silent cotton on the surface of the squeezing component 107; when the first roller 112 contacts the inner wall of the tire, it will adapt to the shape of the inner wall of the tire as the first spring 114 bends and vacuum the inner wall of the tire, so that the equipment can clean the inner wall of the tire, improve the cleanliness of the inner wall of the tire, make the silent cotton fit closely with the inner wall of the tire, and enhance the quality of the device sticking the silent cotton to the inner wall of the tire. ;

When the air pipe 115 exhausts air into the first roller 112 through the fixing seat 119, the air flow inside the second roller 2 will also enter the first roller 112 through the second connecting pipe 24. At this time, the third circular hole 22 will also vacuum and clean the edge of the inner wall of the tire. When the second roller 2 contacts the edge of the inner wall of the tire, it will adapt to the shape of the edge of the tire along with the bending of the second spring 23, thereby increasing the contact area between the equipment and the tire, improving the cleaning ability of the first roller 112 to the inner wall of the tire, and further reducing impurities attached to the inner wall of the tire.

When the support plate 106 reaches a suitable height, the electric slide rail 105 stops moving, and then the drive motor 102 and the linear motor 109 are started. After the drive motor 102 is started, the tray 103 drives the tire to rotate together, and after the linear motor 109 is started, it pushes the first connecting plate 110 to move closer to the tire. When the first connecting plate 110 moves, it moves with the second connecting plate 111, and when the second connecting plate 111 moves, it As the first roller 112 approaches the tire, when the first roller 112 contacts the inner wall of the tire, the first roller 112 will be squeezed by the inner wall of the tire and the first spring 114 will be bent under pressure. When the first spring 114 bends, the angle of the first roller 112 will also change. As the second connecting plate 111 moves, the first roller 112 will gradually adapt to and adhere to the inner wall of the tire. After the first roller 112 contacts the inner wall of the tire, it will rotate under the action of friction. Then, the air pipe 115 is connected to an external air pump so that the air pipe 115 is pumped into the inside of the first roller 112. The gas will flow into the first roller 112 through the fixing seat 119, and then the airflow reaches the first connecting pipe 113 When the gas flows, the impurities attached to the inner wall of the tire will diffuse and enter the first circular hole 116 together with the airflow, so that the device can pre-clean the inner wall of the tire. After the cleaning work is completed, the linear motor 109 can move in the opposite direction to make the second connecting plate 111 away from the tire, and then the extrusion assembly 107 can be started so that the extrusion assembly 107 brings the silent cotton on the surface of the second fixing rod 118 closer to the tire. When the extrusion assembly 107 contacts the tire, it will squeeze the inner wall of the tire and adhere the silent cotton to the inner wall of the tire. After the silent cotton is adhered, the cutting can be started The cutting assembly 108 cuts off the excess mute cotton on the surface of the extrusion assembly 107; when the second connecting plate 111 moves, it will also drive the second roller 2 to move together, and when the second roller 2 moves, it will come into contact with and be squeezed by the edge of the inner wall of the tire, and the second roller 2 will transmit the pressure to the second spring 23 to make the second spring 23 bend, and the second roller 2 will bend along with the bending of the second spring 23 and adhere to the edge of the inner wall of the tire, and when the air pipe 115 exhausts air into the first roller 112 through the fixing seat 119, the air flow inside the second roller 2 will also enter the first roller 112 through the second connecting pipe 24, and at this time, the third circular hole 22 will also vacuum and clean the edge of the inner wall of the tire;Before the equipment starts the extrusion component 107 to stick the silent cotton on the inner wall of the tire, the linear motor 109 can be started without reverse rotation to ensure that the first roller 112 and the inner wall of the tire are always in contact. At this time, the air pipe 115 can be connected to a hot air blower so that the air pipe 115 can send hot air into the first roller 112. The hot air will be ejected from the first circular hole 116 and reach the inner wall of the tire, causing the internal temperature of the tire to rise. When impurities enter the interior of the first roller 112 through the first circular hole 116, they will pass through the first mesh plate 3 and the second mesh plate 32 with the air flow. When the hot air is ejected from the first circular hole 116, the impurities will be fixed under the interception effect of the first mesh plate 3 and the second mesh plate 32, thereby reducing the pressure of the first roller 112 on the inner wall of the tire. When hot, impurities flow out and cause secondary pollution to the tire; when the second connecting plate 111 approaches the tire, the first roller 112 will come into contact with the inner wall of the tire and stop moving, while the slide bar 4 will continue to move with the second connecting plate 111, and the slide bar 4 will move with the top plate 43 when it moves. When the top plate 43 moves, it will come into contact with the surface of the first roller 112 and be squeezed by the first roller 112. When the top plate 43 comes into contact with the first roller 112, the slide bar 4 will slide along the second connecting plate 111 and put the third spring 42 in a stretched state. Then the third spring 42 will apply elastic force to the slide bar 4 and make the slide bar 4 squeeze the top plate 43. The top plate 43 will press the surface of the first roller 112 under the action of the elastic force. The first roller 112 is squeezed to make the first roller 112 and the inner wall of the tire fit more closely, and when the first roller 112 contacts the top plate 43, it will also contact the rotating wheel 44. When the first roller 112 rotates, the top plate 43 will also rotate under the action of friction; when the top plate 43 contacts the first roller 112, the first roller 112 will be squeezed under the elastic force of the top plate 43, so that the first roller 112 is subjected to additional force, ensuring that the first roller 112 can be in close contact with the inner wall of the tire; when the rotating wheel 44 rotates, the convex rod 5 will also rotate together, and when the convex rod 5 rotates, it will contact the first circular hole 116 and clean the inner wall of the first circular hole 116, thereby reducing the impurities remaining on the inner wall of the first circular hole 116. When the protruding rod 5 contacts the first circular hole 116, the first circular hole 116 will be blocked. At this time, the air volume at the remaining unblocked first circular holes 116 will be larger, thereby enhancing the cleaning and heating effect of the equipment on the tire; when the electric slide rail 105 moves, it will move with the third connecting plate 6, and when the third connecting plate 6 moves, it will also move with the orifice plate 62. When the orifice plate 62 moves, it will contact the frame 1. At this time, the protruding block 63 will enter the inside of the fourth circular hole 64, and the orifice plate 62 will be fixed under the friction between the protruding block 63 and the fourth circular hole 64. When the first roller 112 cleans the tire, the orifice plate 62 will intercept the dust diffused in the air, thereby reducing the pollution of the tire by the external environment;When the driving motor 102 is started, the tray 103 will drive the first fixed rod 104 to rotate together. When the first fixed rod 104 rotates, it will rotate together with the second magnet 76. When the second magnet 76 rotates, the distance between it and the first magnet 75 will change. When the first magnet 75 and the second magnet 76 are close to each other, the first magnet 75 will be affected by the repulsive force of the second magnet 76. Then the first magnet 75 will transmit the repulsive force to the connecting rod 72 so that the connecting rod 72 approaches the orifice plate 62. When the connecting rod 72 moves, it will move with the first flexible rod 73 and the second flexible rod 74 and bend the torsion spring. The first flexible rod 73 and the second flexible rod 74 will contact the orifice plate 62 and clean and dredge the mesh on the surface of the orifice plate 62, thereby improving the convenience of the equipment for cleaning the orifice plate 62. After the second magnet 76 moves away from the first magnet 75, the connecting rod 72 will be reset under the action of the torsion spring. When the connecting rod 72 reciprocates under the action of the magnetic force between the first magnet 75 and the second magnet 76, the first ball 82 will also move with the connecting rod When the first ball 82 shakes, the first pull rope 8 will also start to shake. When the first pull rope 8 shakes, the second flexible rod 74 will shake. When the second flexible rod 74 shakes, it will contact with more mesh holes on the surface of the orifice plate 62, thereby enhancing the cleaning effect of the device on the surface of the orifice plate 62; when the first fixing rod 104 contacts the outer wall of the tire, the flexible plate 9 will also contact the outer wall of the tire. Because the flexible plate 9 is a flexible material, when the flexible plate 9 contacts the outer wall of the tire, part of the area will sink into the pattern area of ​​the outer wall, thereby increasing the contact area between the first fixing rod 104 and the tire, thereby improving the stability of the device fixing the tire; when the flexible plate 9 contacts the tire, the second pull rope 1001 and the second ball 1002 will also contact the outer wall of the tire, the second pull rope 1001 will bend under the squeezing action of the tire, and when the second ball 1002 contacts the outer wall of the tire, it will enter the pattern on the surface of the tire, thereby further increasing the contact area between the first fixing rod 104 and the tire, thereby reducing the shaking of the tire when the silent cotton is pasted. ;
