Description

Technical Field

[0001] The utility model relates to the technical field of silent sponge tire processing, in particular to a pressure-maintaining mechanism used for silent sponge tire processing. Background Art

[0002] Tire noise is caused by the friction between the tires and the road when the vehicle is traveling at high speed. The amount of tire noise is determined by the road and vehicle conditions. The worse the road conditions, the greater the tire noise. In addition, there is a big difference in tire noise caused by asphalt roads and concrete roads. For this reason, silent sponges are often installed inside car tires for sound insulation.

[0003] After the silent sponge contacts the glue on the tire, it is necessary to maintain pressure between the silent sponge and the tire to bond and fix the silent sponge to the tire. Therefore, a pressure maintaining mechanism for silent sponge tire processing is proposed to solve the above-mentioned problem. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a pressure-maintaining mechanism for processing silent sponge tires, which can perform silent sponge pressure-maintaining processing on tires of different sizes and has a high degree of automation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure-maintaining mechanism for processing silent sponge tires, comprising a frame and a tire body, a lifting frame is installed on the top of the frame, the bottom of the lifting frame is bolted to a limiting frame, a first translation frame is clamped on one side of the bottom of the limiting frame, a driving gear is installed inside the first translation frame, the driving wheel is not limited to a gear, a pulley, or a sprocket can be used, a gear mounting frame is installed on the side of the first translation frame, a driven gear is clamped on the side of the gear mounting frame, the external transmission of the driving gear and the driven gear is connected with a pressure-maintaining conveyor belt, during use, the conveyor belt contacts the sponge to press the sponge, and the conveyor belt can also be removed and the sponge can be directly pressed by the gear.

[0006] Furthermore, a pressure-maintaining roller is installed on one side of the frame, and the pressure-maintaining roller and the tire body are in contact with each other.

[0008] Furthermore, a motor or a cylinder is installed on the top of the second translation frame, and the output shaft of the motor or the cylinder on the top of the second translation frame is meshed with a bidirectional screw through a bevel gear. This component is a mechanism for expanding the tire mouth. In actual operation, the bidirectional screw drives a pair of expansion devices to shrink or expand relatively at the same time to expand the tire mouth.

[0009] Furthermore, a limiting platform assembly is installed at the bottom of the frame.

[0010] Furthermore, an electric guide rail and a support platform are installed on one side of the top of the limit table assembly, and a clamping frame is provided on the top of the electric guide rail. One end of the clamping frame is transmission-connected to a clamping roller.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides the following embodiments: Specific embodiment one:

[0026] See also Figure 1-8 A pressure-maintaining mechanism for processing silent sponge tires comprises a frame 1 and a tire body 18, a cylinder is connected to the top of the frame 1, a lifting frame 2 is connected to the bottom of the piston of the cylinder, a limiting frame 3 is connected to the bottom of the lifting frame 2, a cylinder is mounted on the limiting frame 3, the piston of the cylinder is connected to a first translation frame 4, a motor / cylinder is fixedly mounted on the first translation frame 4, a driving gear 6 is connected to the output shaft end of the motor / cylinder, it should be noted that the driving wheel here is not limited to a gear, it can also be a pulley or a sprocket, a gear mounting frame 7 is mounted on the first translation frame 4, a driven gear 8 is mounted on the side of the gear mounting frame 7, a pressure-maintaining conveyor belt 9 is connected to the external transmission of the driving gear 6 and the driven gear 8, during use, the conveyor belt 9 contacts the sponge and presses the sponge, or the conveyor belt can be removed and the gear 8 can be used to directly press the sponge.

[0027] Furthermore, the frame 1 supports the mechanism to maintain the balance and stability of the mechanism. The cylinder on the frame 1 drives the lifting frame 2 to move up and down. The limit frame 3 is installed on the lifting frame 2 and can move synchronously with the lifting frame 2.

[0028] Furthermore, the cylinder on the limit frame 3 plays a role in pushing the first translation frame 4 and the second translation frame 5 to move. The driving gear 6 is driven by either the motor / cylinder. The driving gear 6 and the driven gear 8 are connected by a pressure-maintaining conveyor belt 9, so that the driving gear 6, the driven gear 8 and the pressure-maintaining conveyor belt 9 can rotate synchronously. It should be noted that the power source can be either pneumatically driven or electrically driven.

[0029] Furthermore, the gear mounting frame 7 plays a role in maintaining the stability of the driven gear 8 and facilitating the disassembly and assembly of the driven gear 8. The number of driven gears 8 installed on the gear mounting frame 7 can be adjusted to adapt to pressure-maintaining conveyor belts 9 of different widths, so that the pressure-maintaining mechanism can process tires of different sizes.

[0030] Furthermore, the motor / cylinder on the side of the pressure-maintaining roller 10 can play a role in pushing the pressure-maintaining roller 10 to contact the tire body 18 .

[0031] Furthermore, the second translation frame 5 is driven by either a motor or a cylinder.

[0032] Furthermore, the bidirectional screw 11 is driven by either a motor or a cylinder. There are scale blocks on both sides of the bidirectional screw 11. When the bidirectional screw 11 rotates, it can drive the scale blocks to move toward each other. When the scale blocks move toward the two sides away from each other, the tire body 18 can be opened.

[0033] Furthermore, the limiting platform assembly 12, the electric guide rail 13 and the supporting platform 14 are all driven by either a motor or a cylinder.

[0034] Furthermore, the electric guide rail 13 drives the clamping frame 15 to move toward each other. The clamping frame 15 is rotationally connected to the clamping roller 16 to maintain the stability of the clamping roller 16. The clamping roller 16 supports and fixes the tire body 18.

[0035] Furthermore, the support rollers 17 play a role in supporting the tire body 18, and the support rollers 17 are distributed around the center point of the support platform 14, so that the tire body 18 can move slightly on the support rollers 17, making it convenient for the clamping rollers 17 to push the tire body 18 and straighten the tire body 18.

[0036] Follow the steps below during use:

[0037] In step one, the electric guide rail 13 drives the clamping frame 15 and the clamping roller 16 to move. The clamping roller 16 pushes the tire body 18 to be aligned and clamps the tire body 18 to be fixed. It should be noted that the clamping roller 16 and the pressure-maintaining roller 10 move relatively synchronously to fix the position of the sponge.

[0038] Step 2: The pressure-maintaining conveyor belt 9 is driven by the cylinder to move down to a position corresponding to the height of the tire, and the support block is driven by either the corresponding motor / cylinder to move into the tire body 18, and the bidirectional screw 11 is driven to rotate, so that the support block moves toward the two sides away from each other, and the two sides of the tire body 18 are opened to facilitate the pressure-maintaining conveyor belt 9 to enter the tire body 18.

[0039] Step 3: The air cylinders / motors on both sides drive the pressure-maintaining conveyor belt 9 and the pressure-maintaining roller 10 to squeeze the tire body 26 and the silent sponge.

[0040] Step 4: Drive the pressure-maintaining conveyor belt 9 to rotate through either the motor or the cylinder, and drive the tire body 18 to rotate through the corresponding motor or the cylinder, and perform pressure maintenance between the silent sponge and the tire body 18, so that the silent sponge is attached to the inside of the tire body 18 for one circle. Specific embodiment 2:

[0042] See also Figure 1-8 In this device, the external drive and the internal rolling move relatively synchronously, so that the sponge position is fixed, and the clamping roller 16 rotates to provide power to the tire body 18. The tire body 18 as a whole has two rotation modes, and there is also a driving mode similar to the sponge sticking and glue coating form. The tire body 18 is grasped by a claw and rotates with the tire. In this way, the opposite pressure roller 10 is not needed. The advantage is that the pressing angle can be accurately known. The rotation speed of the internal pressure roller and the tire body 18 is adjustable and kept matching, so as to achieve single-sided (inside of the tire) rolling.

[0043] To sum up, the pressure-maintaining mechanism used for processing silent sponge tires can perform pressure-maintaining and pasting operations on tires and silent sponges of different widths by adjusting the number of driven gears 8 and the width of the pressure-maintaining conveyor belt 9. The processing process of pressure-maintaining and pasting the tire body 18 and the silent sponge is highly automated, thereby improving processing efficiency.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
