Description

Technical Field

[0001] This invention relates to the technical field of giant tire production, and in particular to a giant tire burr trimming device. Background Technology

[0002] Tires are ring-shaped rubber products mounted on the rims (wheels) of automobiles and other vehicles. They are the only part of the vehicle that comes into contact with the ground. After the tire is formed, it needs to have its burrs removed by means of a tire production trimming device disclosed in invention patent CN119526659B and a simple tire bead trimming device disclosed in invention patent CN105773885B.

[0003] However, during the production process, it was found that existing trimming equipment is only suitable for trimming tires of ordinary size. It is difficult to trim giant tires used on non-road engineering vehicles such as giant mining dump trucks and large loaders. Furthermore, debris easily falls into the tire's interior during the trimming process, requiring subsequent cleaning of the tire's interior, which is time-consuming and labor-intensive, resulting in poor practicality. Therefore, there is an urgent need for a giant tire burr trimming equipment to improve the above problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a giant tire edge trimming device that uses a conveying mechanism to transport a giant tire to a support mechanism, then the support mechanism to lift the giant tire, then the support mechanism to clamp the giant tire and stand it upright, and then a trimming mechanism to remove the burrs on the tread and bead of the giant tire. At the same time, a cleaning mechanism removes the debris that has fallen into the giant tire. After the burrs are removed, the support mechanism puts the giant tire back onto the conveying mechanism, and the conveying mechanism sends the giant tire out, thereby improving the practicality of the equipment.

[0005] The present invention provides a giant tire burr trimming device, which includes a conveying mechanism; it also includes a support mechanism, a trimming mechanism and a cleaning mechanism, wherein the support mechanism is installed in the middle of the conveying mechanism, and the trimming mechanism and the cleaning mechanism are both installed on the support mechanism. The conveying mechanism transports the giant tire, the supporting mechanism supports the giant tire and stands it upright, the trimming mechanism removes the burrs on the tire tread and bead, and the cleaning mechanism cleans up the debris that has fallen into the giant tire. The giant tire is transported to the support mechanism via a conveyor, then the support mechanism lifts the giant tire, clamps it, and stands it upright. A trimming mechanism removes burrs from the tread and bead of the giant tire, while cleaning removes any debris that has fallen inside the giant tire. After the burrs are removed, the support mechanism places the giant tire back onto the conveyor, which then sends it out, thus improving the equipment's usability.

[0006] Preferably, the support mechanism includes a base, multiple sets of support seats, a lifting mechanism, and a drive mechanism. The multiple sets of support seats and the lifting mechanism are both mounted on the base, and the drive mechanism is mounted on the lifting mechanism. The lifting mechanism supports the giant tire, and the drive mechanism clamps the giant tire. Then, the lifting mechanism raises the giant tire, and the drive mechanism drives the giant tire to rotate, which facilitates the trimming mechanism to remove burrs from the tread and bead of the giant tire.

[0007] Preferably, the lifting mechanism includes a second support base, a frame, a first hydraulic cylinder, a second hydraulic cylinder, a lifting frame, multiple sets of guide columns, and multiple sets of support platforms. The second support base is mounted on the base, one end of the frame is rotatably mounted on the second support base, one end of the first hydraulic cylinder is hinged to the base, and the other end of the first hydraulic cylinder is hinged to the frame. The second hydraulic cylinder and the multiple sets of guide columns are both fixedly mounted on the frame, and the lifting frame is slidably mounted on the multiple sets of guide columns. One end of the second hydraulic cylinder is connected to the lifting frame, and the multiple sets of support platforms are all mounted on the top of the lifting frame. By extending the second hydraulic cylinder, the lifting frame is guided by the guide columns, so that the support platforms support the giant tire. Then, the giant tire is clamped by the drive mechanism, and then the frame is erected by extending the first hydraulic cylinder, thereby erecting the giant tire.

[0008] Preferably, the drive mechanism includes multiple sets of hydraulic arms, multiple sets of fixed frames, multiple sets of drive wheels, multiple sets of drive motors, multiple sets of hydraulic arms, multiple sets of fixed frames, and multiple sets of driven wheels. Multiple sets of hydraulic arms are mounted on the frame. Multiple sets of fixed frames are mounted on the hydraulic arms. Multiple sets of drive wheels and multiple sets of driven wheels are rotatably mounted on the fixed frames. Multiple sets of drive motors are mounted on the fixed frames and provide power to the drive wheels. By retracting the hydraulic arms, the drive wheels and driven wheels clamp the giant tire. After the frame is erected, the multiple sets of drive motors operate synchronously, causing the drive wheels to rotate and thus rotating the giant tire.

[0009] Preferably, the trimming mechanism includes a tread trimming mechanism and a bead trimming mechanism. The tread trimming mechanism is mounted on the frame, and the bead trimming mechanism is mounted on the tread trimming mechanism. The tread trimming mechanism removes burrs from the tread of the giant tire, and the bead trimming mechanism removes burrs from the bead of the giant tire.

[0010] Preferably, the tread trimming mechanism includes a slide rail, an electric slider, a support plate, and a trimming blade. The slide rail is mounted on the frame, the electric slider is mounted on the slide rail, and the trimming blade is mounted on the electric slider via the support plate. The electric slider slides on the slide rail, bringing the trimming blade close to the tread of the giant tire. Then, during the tire's rotation, the trimming blade cuts off the rough edges on the tread.

[0011] Preferably, the tire bead trimming mechanism includes two sets of sliders, a positive and negative lead screw, a second drive motor, two sets of three hydraulic arms, and two sets of trimming blades. Both sets of sliders are slidably mounted on a support plate, and the positive and negative lead screws are rotatably mounted on the support plate, with threaded connections between the lead screws and the two sets of sliders. The second drive motor is fixedly mounted on the support plate, and its output shaft is connected to one end of the positive and negative lead screws. The two sets of three hydraulic arms are respectively mounted on the two sets of sliders, and the two sets of trimming blades are respectively mounted on the two sets of three hydraulic arms. By turning on the second drive motor, the two sets of sliders move towards each other via the positive and negative lead screws, adjusting the position of the two sets of trimming blades. Then, by retracting the two sets of three hydraulic arms, the two sets of trimming blades approach the tire bead of the giant tire. As the giant tire rotates, the two sets of trimming blades remove the burrs from the tire bead.

[0012] Preferably, the cleaning mechanism includes a suction pipe, an electric control valve, and a telescopic mechanism. The suction pipe is installed on the frame, the electric control valve is installed at the bottom of the suction pipe, and the telescopic mechanism is installed on the frame and the suction pipe. The electric control valve is connected to the suction pipe in the workshop, and then the telescopic mechanism is operated to adjust the suction position. Then the electric control valve is opened to suck out the debris inside the giant tire.

[0013] Preferably, the telescopic mechanism includes a telescopic tube, an air suction pump, an exhaust pump, and a three-way solenoid valve. The air suction pump is mounted on the suction pipe, and a cavity is provided in the side wall of the air suction pump. Both the air suction pump and the exhaust pump are mounted on the frame. The three-way solenoid valve is mounted on the suction pipe, and the exhaust port of the three-way solenoid valve communicates with the cavity in the side wall of the telescopic tube. The two sets of connection ports of the three-way solenoid valve are respectively connected to the air suction port of the air suction pump and the exhaust port of the exhaust pump. When the exhaust pump is running, air is discharged into the cavity of the telescopic tube through the three-way solenoid valve, allowing the telescopic tube to extend into the interior of the giant tire. This facilitates the telescopic tube and the suction pipe to work together to suck out debris from the giant tire. After the giant tire is trimmed, the exhaust pump is turned off, and the air suction pump is run to expel the air from the cavity of the telescopic tube, thereby causing the telescopic tube to retract.

[0014] Preferably, the conveying mechanism includes two sets of guide rails, two sets of support seats, two sets of roller conveyors, and two sets of limit bolts. The two sets of support seats are slidably installed on the two sets of guide rails, the two sets of roller conveyors are fixedly installed on the two sets of support seats, and the two sets of limit bolts are threaded onto the two sets of support seats. By sliding the support seats on the guide rails, the distance between the two sets of roller conveyors is adjusted. Then, the limit bolts are tightened to limit the support seats. After that, the giant tire is placed on the roller conveyor, and the giant tire is conveyed by the operation of the roller conveyor.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The giant tire is erected and driven to rotate by the lifting and flipping mechanism, and with the adjustable trimming cutter, the problem of the burrs on the giant tire that traditional equipment cannot handle is effectively solved. 2. By using the drive wheel to rotate the tire at a constant speed, and combining the electric slider and lead screw to adjust the position of the trimming knife, the burrs on the tire tread and bead are removed automatically and with high precision. 3. The built-in retractable suction pipe can suck up the fallen debris while trimming, eliminating the need for subsequent manual cleaning of the inside of the tire and significantly improving production efficiency.

The trimming mechanism includes a tread trimming mechanism and a bead trimming mechanism. The tread trimming mechanism is mounted on the frame 4, and the bead trimming mechanism is mounted on the tread trimming mechanism. The tread trimming mechanism includes a slide rail 17, an electric slider 18, a support plate 19, and a trimming blade 20. The slide rail 17 is mounted on the frame 4, the electric slider 18 is mounted on the slide rail 17, and the trimming blade 20 is mounted on the electric slider 18 via the support plate 19.

A second hydraulic cylinder 6 extends, guiding the lifting frame 7 via a guide column 8, allowing the support platform 9 to support the giant tire. Then, multiple sets of hydraulic arms 10 and 14 retract, clamping the giant tire between multiple drive wheels 12 and driven wheels 16. Next, a first hydraulic cylinder 5 extends, erecting the frame 4. The second hydraulic cylinder 6 retracts and resets, again erecting the giant tire. Multiple drive motors 13 operate synchronously, rotating the drive wheels 12 and causing the giant tire to rotate. Simultaneously, an electric slider 18 slides on a slide rail 17, bringing the trimming blade 20 close to the tread of the giant tire. Then, the wheels... During tire rotation, the burrs on the tire surface are cut off by the trimming blade 20. By turning on the drive motor 23, the two sets of sliders 21 move towards each other via the forward and reverse screws 22, adjusting the position of the two sets of trimming blades 25. Then, the two sets of hydraulic arms 3 24 retract, bringing the two sets of trimming blades 25 closer to the bead of the giant tire. As the giant tire rotates, the two sets of trimming blades 25 remove the burrs from the bead. After the burrs are removed, trimming blades 20 and 25 return to their original positions, and hydraulic cylinder 2 6 extends again, causing the support platform 9 to rest against the giant tire. The frame 4 then returns to its original position, and hydraulic cylinder 2 6 retracts again, placing the giant tire back onto the roller conveyor 34, which then transports the giant tire away, thus improving the practicality of the equipment.

[0020] Example 2 A giant tire burr trimming device, based on Embodiment 1, further includes: The cleaning mechanism includes a suction pipe 26, an electric control valve 27, and a telescopic mechanism. The suction pipe 26 is mounted on the frame 4, the electric control valve 27 is mounted at the bottom of the suction pipe 26, and the telescopic mechanism is mounted on the frame 4 and the suction pipe 26. The telescopic mechanism includes a telescopic tube 28, an air suction pump 29, an exhaust pump 30, and a three-way solenoid valve 31.

The three-way solenoid valve 31 is installed on the suction pipe 26, and the exhaust port of the three-way solenoid valve 31 is connected to the cavity in the side wall of the telescopic tube 28. The two sets of connection ports of the three-way solenoid valve 31 are respectively connected to the air suction port of the air suction pump 29 and the exhaust port of the exhaust pump 30. A giant tire is placed on a roller conveyor 34. The roller conveyor 34 transports the giant tire to above a support platform 9. A second hydraulic cylinder 6 extends, guiding the lifting frame 7 via a guide column 8, allowing the support platform 9 to support the giant tire. Then, multiple sets of hydraulic arms 10 and 14 retract, clamping the giant tire between multiple drive wheels 12 and driven wheels 16. A first hydraulic cylinder 5 extends, raising the frame 4. The second hydraulic cylinder 6 retracts and resets, raising the giant tire. Multiple drive motors 13 operate synchronously, rotating the drive wheels 12 and causing the giant tire to rotate. Simultaneously, an electric slider 18 slides on a slide rail 17, bringing the trimming blade 20 close to the tire tread. During tire rotation, the trimming blade 20 removes burrs from the tire tread. By activating a second drive motor 23, the forward and reverse screws 22 drive two sets of sliders 21 to move towards each other, adjusting the two sets of trimming blades 25. The machine is positioned so that the two sets of hydraulic arms 24 retract, bringing the two sets of trimming blades 25 close to the bead of the giant tire. As the giant tire rotates, the two sets of trimming blades 25 remove the burrs from the bead. After the burrs are removed, trimming blades 20 and 25 return to their original positions, and hydraulic cylinder 26 extends again, causing the support platform 9 to rest against the giant tire. The frame 4 then returns to its original position, and hydraulic cylinder 26 retracts again, placing the giant tire back onto the roller conveyor 34, which then carries the giant tire away. During the trimming process, the exhaust pump 30 operates, and air is discharged into the cavity of the telescopic tube 28 through the three-way solenoid valve 31, allowing the telescopic tube 28 to extend into the interior of the giant tire. The solenoid valve 27 opens, sucking out the debris from inside the giant tire. After the trimming of the giant tire is completed, the exhaust pump 30 is closed, and the suction pump 29 operates to expel the air from the cavity of the telescopic tube 28, causing the telescopic tube 28 to retract, thereby improving the practicality of the equipment.

[0021] The main functions achieved by this invention are: 1. The giant tire is erected and driven to rotate by the lifting and flipping mechanism, and with the adjustable trimming cutter, the problem of the burrs on the giant tire that traditional equipment cannot handle is effectively solved. 2. By using the drive wheel to rotate the tire at a constant speed, and combining the electric slider and lead screw to adjust the position of the trimming knife, the burrs on the tire tread and bead are removed automatically and with high precision. 3. The built-in retractable suction pipe can suck up the fallen debris while trimming, eliminating the need for subsequent manual cleaning of the inside of the tire and significantly improving production efficiency.
