Description

Technical Field

[0001] This utility model relates to the field of rubber tire compaction technology, and in particular to a rubber tire tread forming and compaction device. Background Technology

[0002] A wheel is a rigid wheel that fixes the inner edge of the tire, supports the tire, and shares the load with the tire. The wheel assembly consists of two main parts: the inner wheel and the outer tire. The outer tire of a children's vehicle wheel is usually heated to expand it before being put on the outside of the inner wheel. After the outer tire is put on the outside of the inner wheel, there are usually imperfections in the fit. Therefore, it needs to be compacted and shaped again to meet the quality requirements. Therefore, a rubber tire tread forming and compacting device is required.

[0003] For example, the patent specification of an existing Chinese patent (publication number: CN210211437U) discloses a device for forming and compacting the tread of rubber tires for children's vehicles. When forming and compacting the tread of rubber tires of different sizes and specifications, the device can be used to compact rubber tires of different sizes and specifications by replacing the arc plate with one of the same size and specifications as the rubber tire. This makes the device versatile and improves its practicality.

[0004] However, in implementing the relevant technology, the above-designed children's vehicle rubber tire tread forming and compaction device has the following problems: the push block and arc plate on the children's vehicle rubber tire tread forming and compaction device are set as detachable structures, so that the arc plate with the same size and specifications as the rubber tire can be replaced, thus making it suitable for compacting different tires. However, disassembly takes time, which not only reduces processing efficiency but also increases the workload of personnel. In view of this, a rubber tire tread forming and compaction device is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rubber tire tread forming and compaction device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rubber tire tread forming and compaction device, comprising an operating table, a fixed frame fixedly installed on the top of the operating table, a fixed shaft fixedly installed at the center of the front side of the fixed frame, a first airbag ring sleeved on the fixed shaft, a fixed ring fixedly installed on the front side of the fixed frame, a second airbag ring provided in the inner ring of the fixed ring, the first airbag ring being located in the inner ring of the second airbag ring, and an inflation component for inflating the first airbag ring and the second airbag ring being provided in the rear side of the fixed frame.

[0007] As a further description of the above technical solution: the inflation assembly includes an air collection box, which is fixedly installed on the rear side of the fixing frame. An air supply pipe and a connecting pipe are fixedly inserted into the top and one side of the air collection box, respectively. The other ends of the air supply pipe and the connecting pipe pass through the fixing frame and are fixedly inserted into the second airbag ring and the first airbag ring, respectively. Two one-way exhaust valves are provided in the air collection box, and the two one-way exhaust valves are respectively connected to the ends of the air supply pipe and the connecting pipe. A one-way air inlet valve is also provided on one side of the air collection box. A first valve and a second valve are also provided on the air supply pipe and the connecting pipe, respectively. An inflation component is provided in the air collection box for guiding air into the air supply pipe and the connecting pipe.

[0008] As a further description of the above technical solution: the inflation component includes a slide rod, which is slidably inserted into the bottom of the air collection box. A piston is fixedly installed on the top of the slide rod, and the piston is slidably connected inside the air collection box. An air vent is provided at the bottom of one side of the air collection box, and the air vent is connected to the inside of the air collection box.

[0009] As a further description of the above technical solution: a pull block is fixedly installed at the end of the slide rod away from the piston. The diameter of the pull block is larger than the diameter of the slide rod, which makes it convenient for personnel to push and pull the slide rod, bringing convenience to the operator.

[0010] As a further description of the above technical solution: the outer surface of the pull block is provided with anti-slip texture. By providing anti-slip texture on the pull block, the friction between the person's hand and the pull block can be increased, thereby helping to solve the problem of slipping when the person pushes the pull block.

[0011] As a further description of the above technical solution: the inner ring of the second airbag ring and the outer surface of the first airbag ring are both coated with wear-resistant paint, which improves the wear resistance of the first airbag ring and the second airbag ring and helps to extend the service life of the first airbag ring and the second airbag ring.

[0012] As a further description of the above technical solution: a return spring is also movably sleeved on the slide rod. The return spring is set between the piston and the bottom wall of the gas collection box. By setting the return spring, the piston can be pulled down and reset by the elastic force of the return spring itself when the personnel release the pull block, which can further reduce the workload of the personnel.

[0013] This utility model has the following beneficial effects:

[0014] The rubber tire tread forming and compaction device designed in this utility model involves fitting the tire onto the first airbag ring, and then, with the help of an inflation component, inflating the first airbag ring to facilitate stable positioning of the tire. Then, with the help of the inflation component, the second airbag ring can also be inflated until the second airbag ring completely covers the outer surface of the tire, thereby compacting the tire. In addition, this device can also easily perform compaction operations on tires of different diameters, improving the convenience of use.

[0015] The rubber tire tread forming and compaction device designed in this utility model has a reset spring. When the operator releases the pull block, the piston is pulled down and reset by the spring's own elasticity, which can further reduce the operator's workload. By setting anti-slip texture on the pull block, the friction between the operator's hand and the pull block can be increased, which helps to solve the problem of slippage when the operator pushes the pull block.

[0022] Reference Figure 1-4 The present invention provides a rubber tire tread forming and compaction device, including an operating table 1, a fixed frame 2 fixedly installed on the top of the operating table 1, a fixed shaft 3 fixedly installed at the center of the front side of the fixed frame 2, a first airbag ring 4 sleeved on the fixed shaft 3, a fixed ring 5 fixedly installed on the front side of the fixed frame 2, a second airbag ring 6 provided in the inner ring of the fixed ring 5, the first airbag ring 4 located in the inner ring of the second airbag ring 6, and an inflation component for inflating the first airbag ring 4 and the second airbag ring 6 provided in the rear side of the fixed frame 2.

[0023] The inflation assembly includes an air collection box 7, which is fixedly installed on the rear side of the fixing frame 2. An air supply pipe 8 and a connecting pipe 9 are fixedly inserted into the top and one side of the air collection box 7, respectively. The other ends of the air supply pipe 8 and the connecting pipe 9 pass through the fixing frame 2 and are fixedly inserted into the second airbag ring 6 and the first airbag ring 4, respectively. Two one-way exhaust valves 10 are provided in the air collection box 7. The two one-way exhaust valves 10 are connected to the ends of the air supply pipe 8 and the connecting pipe 9, respectively. A one-way air inlet valve 11 is also provided on one side of the air collection box 7. A first valve 12 and a second valve 13 are also provided on the air supply pipe 8 and the connecting pipe 9, respectively. An inflation component is provided in the air collection box 7 for guiding air into the air supply pipe 8 and the connecting pipe 9.

[0024] The inflation component includes a slide rod 14, which is slidably inserted into the bottom of the air collection box 7. A piston 15 is fixedly installed on the top of the slide rod 14 and is slidably connected inside the air collection box 7. An air vent 16 is provided at the bottom of one side of the air collection box 7 and is connected to the inside of the air collection box 7.

[0025] In practice, the tire to be compacted is first fitted onto the first airbag ring 4. Then, the second valve 13 is opened and the first valve 12 is closed. Next, the pull block 17 is pushed upward, which causes the pull block 17 to drive the slide rod 14 and the piston 15 to slide upward in the air collection box 7. During this process, the air above the piston 15 is injected into the first airbag ring 4 through the connecting pipe 9 and one of the one-way exhaust valves 10. When the piston 15 moves downward, outside air can enter the air collection box 7 through the one-way intake valve 11. This process is repeated to stabilize the tire. Then, following the same principle, air is injected into the second airbag ring 6 through the air supply pipe 8 until the second airbag ring 6 completely covers the outer surface of the tire, thus compacting the tire. In addition, based on the above principle, it is convenient to compact tires of different diameters, improving the ease of use.

[0026] As a further implementation of the above technical solution: a pull block 17 is fixedly installed at the end of the slide rod 14 away from the piston 15, and the diameter of the pull block 17 is larger than the diameter of the slide rod 14. This facilitates the pushing and pulling of the slide rod 14, providing convenience for the operator.

[0027] As a further implementation of the above technical solution: the outer surface of the pull block 17 is provided with anti-slip texture. By providing anti-slip texture on the pull block 17, the friction between the person's hand and the pull block 17 can be increased, thereby helping to solve the problem of slippage when the person pushes the pull block 17.

[0028] As a further implementation of the above technical solution: the inner ring of the second airbag ring 6 and the outer surface of the first airbag ring 4 are both coated with a wear-resistant coating. This improves the wear resistance of the first airbag ring 4 and the second airbag ring 6, and helps to extend the service life of the first airbag ring 4 and the second airbag ring 6.

[0029] As a further implementation of the above technical solution: a return spring 18 is also movably sleeved on the slide rod 14, and the return spring 18 is located between the piston 15 and the bottom wall of the air collection box 7. By setting the return spring 18, when the personnel release the pull block 17, the piston 15 can be pulled down and reset due to the elastic force of the return spring 18 itself, which can further reduce the workload of the personnel.

[0030] Working principle:

[0031] Before using this utility model, all electrical components involved in the rubber tire tread forming and compacting device need to be connected to an external power source, or a battery pack needs to be installed in an area outside the operating table 1 that does not obstruct other components. Then, the battery pack is connected to the electrical components through a line to supply power to the electrical components, thereby ensuring their normal operation. Since connecting the electrical components to an external power source or setting up a battery pack for power supply is existing technology and is not a problem that needs to be solved in the background technology of this specification, it will not be explained in detail.

[0032] In use, first, the tire to be compacted is fitted onto the first airbag ring 4. Then, the second valve 13 is opened and the first valve 12 is closed. Next, the pull block 17 is pushed upward, which causes the pull block 17 to drive the slide rod 14 and the piston 15 to slide upward in the air collection box 7. During this process, the air above the piston 15 is injected into the first airbag ring 4 through the connecting pipe 9 and one of the one-way exhaust valves 10. When the piston 15 moves downward, outside air can enter the air collection box 7 through the one-way intake valve 11. Repeating this process can stably position the tire. Then, following the same principle, air can be injected into the second airbag ring 6 through the air supply pipe 8 until the second airbag ring 6 completely wraps the outer surface of the tire, thereby compacting the tire. In addition, based on the above principle, it is convenient to compact tires of different diameters, improving the convenience of use.

[0033] By setting a reset spring 18, the piston 15 can be pulled down and reset by the elastic force of the reset spring 18 when the person releases the pull block 17, which can further reduce the workload of the person. By setting anti-slip texture on the pull block 17, the friction between the person's hand and the pull block 17 can be increased, which helps to solve the problem of slippage when the person pushes the pull block 17.

[0034] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
