[0002] Tires are circular, elastic rubber products that roll against the ground and are installed on various vehicles or machinery. Typically mounted on metal rims, they support the vehicle's body, cushion external impacts, maintain contact with the road, and ensure the vehicle's driving performance.

[0003] After searching, the existing patent with publication number "CN208276670U" for "A grinding device for automobile tire mold" is found: it includes a fixed frame, the side wall of the vertical plate of the fixed frame is fixed with a guide rail by rivets, the side wall of the guide rail is slidably connected to the support plate, one end of the side wall of the support plate is provided with a through hole, and the inner wall of the through hole is fixed with a track by rivets, the side wall of the track is slidably connected to a sliding rod, one end of the sliding rod is fixed to the upper end of the rotating frame by a screw, one end of the rotating frame is threadedly connected to a transmission shaft, the transmission shaft is connected to the first motor through a coupling, the first motor is placed on the upper end of the support plate, and the support plate is welded with a support frame on the upper wall near the sliding rod. The upper side wall of the electric push rod is fixed with a screw, and one end side wall of the electric push rod is installed on the upper end of the fixed frame by screws. Through the arrangement of the fixed frame, the electric push rod, the first motor, the support plate, the fixed plate, the sliding rod, the rotating frame and the sliding block, the first motor drives the rotating frame and the sliding rod to rotate along the track, and the sliding block rotates cyclically around the sliding groove, which plays an auxiliary supporting role in the movement of the grinding disc, thereby ensuring the safety during the grinding process of the tire mold. The simultaneous rotation of the first motor and the second motor can drive the grinding disc to rotate, perform a cyclic circular motion around the tire mold, and cyclically grind the outer surface of the tire mold, thereby improving the working efficiency of the tire grinding.

[0004] However, the above patent still has shortcomings in actual use: since tire molds on the market vary in size, the grinding roller of this patent cannot be adjusted and can only be used to grind tire molds of a certain specification. It has a narrow scope of application and low practicality. In addition, during the grinding process, severe friction is generated between the grinding roller and the tire mold, which will cause the grinding roller and the tire mold to heat up rapidly.

[0016] The present invention has the following beneficial effects:

[0017] 1. By setting up the grinding mechanism and the adjustment mechanism, the distance between the grinding rollers can be adjusted by driving the electric push rod to extend or shorten, so that the entire device can grind tire molds of various specifications, with a wide range of uses and greater practicality;

[0018] 2. When adjusting the distance between the grinding rollers, the adjusting rod will move synchronously, so that the adjusting rod is always in contact with the synchronous belt, so that the synchronous belt remains taut, thereby ensuring normal driving;

[0019] 3. By setting a cooling mechanism, the water pump is started during the grinding process, and water is pumped into the nozzle through the water inlet pipe. The nozzle will spray water onto the grinding area of ​​the grinding roller and the tire mold, thereby effectively cooling the grinding roller and the tire mold to avoid damage caused by high temperature. The sprayed water can also play a certain role in dust reduction.

[0020] 4. By setting a control mechanism, the larger the distance between the grinding rollers, the different positions of the movable block in the groove will be due to the different distances between the grinding rollers, and the contact positions of the conductive block and the resistor bar will be different. As a result, the larger the distance between the grinding rollers, the smaller the resistance of the resistor bar connected to the circuit. At this time, the larger the current in the circuit, the greater the magnetic attraction generated by the electromagnet. At this time, the magnetic block will be closer to the electromagnet, driving the third rotating rod to rotate, and then driving the nozzle to rotate downward, so that the water sprayed by the nozzle is close to the position of the grinding roller, and the water spraying angle of the nozzle can be automatically adjusted according to the distance between the grinding rollers, so that the water spraying angle always follows the grinding roller, which is convenient for cooling;

[0021] 5. Since the distance between the grinding rollers can be adjusted according to the size of the tire mold, and the angle of the nozzle will also be automatically adjusted with the distance between the grinding rollers, the sprayed water can always fall on the contact point between the grinding roller and the tire mold, thereby achieving a better cooling effect. In addition, as the size of the tire mold is larger, if the speed of the motor is always the same, it will take longer to grind one circle. The current supplied to the motor can be adjusted according to the size of the tire mold, and thus the speed of the motor can be adjusted. The smaller the size of the tire mold, the smaller the current supplied, the slower the speed of the motor, and the slower the speed of the grinding roller, which can then allow the tire mold to be finely ground. The larger the size of the tire mold, the greater the current supplied to the motor, and the faster the speed of the grinding roller, which can improve the grinding efficiency.

[0022] 6. By setting up a dust suction mechanism, the rotation of the shaft will synchronously drive the rotation of the cam. Under the cooperation of the second spring, it will drive the T-bar to move back and forth, drive the sliding plug to slide back and forth, and generate suction force. Then, the dust generated during the grinding process will be sucked into the dust removal box through the dust suction hole and the dust suction pipe. Then the dust will be discharged to the external collection box through the dust exhaust pipe, thereby preventing the dust generated during the grinding process from flying into the air and being easily inhaled by surrounding workers, causing harm to their health.

[0023] 7. By setting up a fixing mechanism, the tire mold is placed on the processing table, and the air in the negative pressure cavity is extracted through an external vacuum pump and exhaust pipe, thereby generating negative pressure in the negative pressure cavity. The tire mold is adsorbed and fixed through the negative pressure hole. The tire mold is placed on the processing table, and the air in the negative pressure cavity is extracted through an external vacuum pump and exhaust pipe, thereby generating negative pressure in the negative pressure cavity. The tire mold is adsorbed and fixed through the negative pressure hole to prevent the tire mold from moving during the grinding process. BRIEF DESCRIPTION OF THE DRAWINGS

The inner walls of the multiple slide grooves 8 are symmetrically provided with two card grooves 9, and the inner walls of the two card grooves 9 are slidably connected to two card blocks 10. The side walls of the two card blocks 10 close to each other are commonly fixedly connected to a slider 11, and the upper end of the slider 11 is rotatably connected to the first rotating rod 12. The lower end of the first rotating rod 12 passes through the lower end of the slider 11 and is fixedly connected to the grinding roller 13. A driving assembly is provided on the mounting frame 4.

The side walls of the plurality of second rotating rods 15 are fixedly connected to gears 151, and the gears 151 are meshed with the ring gear 14. The side walls of the second rotating rods 15 are fixedly connected to the driving wheel 16, and the side walls of the first rotating rod 12 are fixedly connected to the driven wheel 17. The driving wheel 16 is connected to the driven wheel 17 through a synchronous belt. The upper end of the mounting frame 4 is fixedly connected to the motor 18 through a bracket, and the output end of the motor 18 passes through the upper end of the mounting frame 4 and is fixedly connected to the rotating shaft 5.

[0036] Furthermore, the hydraulic cylinder 2 is driven to extend, driving the processing table 3 to move upward, and then driving the fixed tire mold to move upward, so that the tire mold contacts the grinding roller 13, and then the motor 18 is driven to rotate, driving the rotating shaft 5 to rotate, and then driving the fixed rod 6 to rotate, driving the circular plate 7 to rotate, and then driving the grinding roller 13 to perform circular motion. Since the gear 151 is engaged with the ring gear 14, the gear 151 will also rotate at this time, driving the second rotating rod 15 to rotate, driving the driving wheel 16 to rotate, driving the driven wheel 17 to rotate, and then driving the first rotating rod 12 to rotate, driving the grinding roller 13 to rotate, thereby grinding the tire mold.

[0037] An adjusting mechanism is installed on the circular plate 7, which includes a plurality of grooves 19 opened at the upper end of the circular plate 7. The inner walls of the plurality of grooves 19 are slidably connected to moving blocks 20. The upper end of the moving block 20 is fixedly connected to an adjusting rod 21. The side wall of the adjusting rod 21 is fitted with a synchronous belt. The side wall of the adjusting rod 21 is rotatably connected to a first connecting rod 22. The side wall sliding sleeve of the first rotating rod 12 is provided with a first sliding sleeve 121 and a second sliding sleeve 122. The other end of the first connecting rod 22 is rotatably connected to the first sliding sleeve 121. An electric push rod 23 is fixedly connected to the upper end of the circular plate 7. The side wall of the movable end of the electric push rod 23 is rotatably connected to the second connecting rod 24. The other end of the second connecting rod 24 is rotatably connected to the side wall of the second sliding sleeve 122.

[0038] Furthermore, by driving the electric push rod 23 to extend or shorten, the second connecting rod 24 is driven to move upward or downward and rotate synchronously. The second connecting rod 24 drives the first rotating rod 12 to move, and then drives the slider 11 to move, drives the grinding roller 13 to move, and adjusts the distance between the grinding rollers 13, so that the entire device can grind tire molds of various specifications, with a wide range of uses and greater practicality.

[0039] A cooling mechanism is installed on the base 1, which includes multiple mounting plates 25 fixedly connected to the upper end of the base 1, wherein the side walls of two mounting plates 25 located on the same side close to each other are jointly rotatably connected to a third rotating rod 26, and the side wall of the third rotating rod 26 is fixedly connected to a nozzle 27, which is connected to an external water pump through a water inlet pipe 28.

[0040] Furthermore, during the grinding process, the water pump is started to pump water into the nozzle 27 through the water inlet pipe 28. The nozzle 27 will spray the water onto the grinding area of ​​the grinding roller 13 and the tire mold, thereby effectively cooling the area and preventing the high temperature from making the grinding roller 13 and the tire mold easily damaged. The sprayed water can also play a certain role in reducing dust.

[0041] A control mechanism is installed on the mounting plate 25, and the control mechanism includes an arc-shaped groove 29 opened on the side wall of the mounting plate 25, a magnetic block 30 is fixedly connected to the side wall of the third rotating rod 26, the magnetic block 30 is slidably connected to the inner wall of the arc-shaped groove 29, a first spring 31 is fixedly connected between the inner wall of the arc-shaped groove 29 and the side wall of the magnetic block 30, an electromagnet 32 ​​is fixedly connected to the inner wall of the arc-shaped groove 29, a resistor bar 33 is fixedly connected to the inner wall of the groove 19, a conductive block 34 is fixedly connected to the side wall of the moving block 20, and the motor 18, the electromagnet 32, the resistor bar 33, the conductive block 34 and the external power supply are electrically connected through wires.

[0042] Furthermore, the larger the distance between the grinding rollers 13, the different positions of the movable block 20 in the groove 19 will be due to the different distances between the grinding rollers 13, and the contact positions of the conductive block 34 and the resistor bar 33 will be different. The larger the distance between the grinding rollers 13, the smaller the resistance of the resistor bar 33 connected to the circuit. At this time, the larger the current in the circuit, and the greater the magnetic attraction generated by the electromagnet 32. At this time, the magnetic block 30 will be closer to the electromagnet 32, driving the third rotating rod 26 to rotate, and then driving the nozzle 27 to rotate downward, so that the water sprayed by the nozzle 27 falls on the contact point between the grinding roller 13 and the tire mold, and the water spraying angle of the nozzle 27 can be automatically adjusted according to the distance between the grinding rollers 13, so that the water spraying angle always follows the grinding roller 13, which is convenient for cooling.

[0043] It is worth mentioning that since the distance between the grinding rollers 13 will be adjusted according to the size of the tire mold, the angle of the nozzle 27 will also be automatically adjusted with the distance between the grinding rollers 13, so that the angle of the water spray can always fall on the contact point between the grinding roller 13 and the tire mold, thereby achieving a better cooling effect. In addition, since the size of the tire mold is larger, if the speed of the motor 18 is always the same, the time required for grinding one circle will be longer, and the current passed through the motor 18 can be adjusted according to the size of the tire mold, and the speed of the motor 18 can be adjusted. The smaller the size of the tire mold, the smaller the current passed, the slower the speed of the motor 18, and the speed of the grinding roller 13 will be slower, so that the tire mold can be finely ground. The larger the size of the tire mold, the greater the current passed through the motor 18, and the speed of the grinding roller 13 will be faster, which can improve the grinding efficiency.

[0044] A dust suction mechanism is installed on the processing table 3, which includes a dust suction chamber 35 opened in the processing table 3, and a plurality of dust suction holes 36 are opened on the inner wall of the dust suction chamber 35. A dust removal box 37 is fixedly connected to the upper end of the mounting frame 4, and a dust exhaust pipe 38 is fixedly connected to the upper end of the dust removal box 37. The other end of the dust exhaust pipe 38 is connected to the external collection box. The dust removal box 37 is connected to the dust suction chamber 35 through a dust suction pipe 39. One-way valves are installed on the inner walls of the dust exhaust pipe 38 and the dust suction pipe 39. The one-way valve installed on the inner wall of the dust exhaust pipe 38 only allows the dust in the dust removal box 37 to be discharged, and the one-way valve installed on the inner wall of the dust suction pipe 39 only allows the dust in the dust suction chamber 35 to enter the dust removal box 37.

[0045] The dust collection mechanism also includes a sliding plug 40 that is sealingly and slidingly connected to the inner wall of the dust removal box 37. The side wall of the dust removal box 37 is slidingly connected to a T-shaped rod 41. One end of the T-shaped rod 41 is fixedly connected to the side wall of the sliding plug 40. The side wall of the T-shaped rod 41 is sleeved with a second spring 42. The two ends of the second spring 42 are respectively fixedly connected to the inner wall of the dust removal box 37 and the side wall of the sliding plug 40. The side wall of the output end of the motor 18 is fixedly connected to a cam 421, and the side wall of the cam 421 slides against the T-shaped rod 41.

[0046] Furthermore, the rotation of the rotating shaft 5 will synchronously drive the cam 421 to rotate, and with the cooperation of the second spring 42, it will drive the T-bar 41 to move back and forth, drive the sliding plug 40 to slide back and forth, generate a suction force, and then the dust generated during the grinding process will be sucked into the dust removal box 37 through the dust suction hole 36 and the dust suction pipe 39, and then the dust will be discharged to the external collection box through the dust exhaust pipe 38, thereby preventing the dust generated during the grinding process from flying into the air, which is easily inhaled by the surrounding workers and enters the body, causing harm to the workers' health.

[0047] A fixing mechanism is installed on the processing table 3, which includes a negative pressure chamber 43 opened in the processing table 3. A plurality of negative pressure holes 44 are opened on the inner wall of the negative pressure chamber 43. An exhaust pipe 45 is fixedly connected to the inner wall of the negative pressure chamber 43, and the other end of the exhaust pipe 45 is connected to an external vacuum pump.

[0048] In the present invention, the tire mold is first placed on the processing table 3, and the air in the negative pressure chamber 43 is extracted through an external vacuum pump and an exhaust pipe 45, thereby generating a negative pressure in the negative pressure chamber 43, and the tire mold is adsorbed and fixed through the negative pressure hole 44. The tire mold is placed on the processing table 3, and the air in the negative pressure chamber 43 is extracted through an external vacuum pump and an exhaust pipe 45, thereby generating a negative pressure in the negative pressure chamber 43, and the tire mold is adsorbed and fixed through the negative pressure hole 44.

[0049] Then, the distance between the grinding rollers 13 is adjusted according to the size of the tire mold. By driving the electric push rod 23 to extend or shorten, the second connecting rod 24 is driven to move upward or downward and rotate synchronously. The second connecting rod 24 drives the first rotating rod 12 to move, and then drives the slider 11 to move, drives the grinding rollers 13 to move, and adjusts the distance between the grinding rollers 13.

[0050] If the size of the tire mold is larger, the slider 11 will be closer to the second rotating rod 15. However, the synchronous belt will become loose at this time, and the first rotating rod 12 will move through the first connecting rod 22, driving the moving block 20 to slide on the inner wall of the groove 19, and then driving the adjusting rod 21 to move, so that the adjusting rod 21 will stretch the synchronous belt, so that the synchronous belt remains taut, thereby ensuring normal drive.

[0051] In addition, the larger the distance between the grinding rollers 13, the position of the moving block 20 in the groove 19 will be different due to the different distances between the grinding rollers 13, and the contact position of the conductive block 34 and the resistor bar 33 will be different. The larger the distance between the grinding rollers 13, the smaller the resistance of the resistor bar 33 connected to the circuit. At this time, the larger the current in the circuit, and the greater the magnetic attraction generated by the electromagnet 32. At this time, the magnetic block 30 will be closer to the electromagnet 32, driving the third rotating rod 26 to rotate, and then driving the nozzle 27 to rotate downward, so that the water sprayed by the nozzle 27 falls on the position where the grinding roller 13 contacts the tire mold, and the water spraying angle of the nozzle 27 can be automatically adjusted according to the distance between the grinding rollers 13, so that the water spraying angle always follows the grinding roller 13, which is convenient for cooling.

[0052] After the distance between the grinding rollers 13 is adjusted, the hydraulic cylinder 2 is driven to extend, driving the processing table 3 to move upward, and then driving the fixed tire mold to move upward, so that the tire mold contacts the grinding roller 13, and then the driving motor 18 is driven to rotate, driving the rotating shaft 5 to rotate, and then driving the fixed rod 6 to rotate, driving the circular plate 7 to rotate, and then driving the grinding roller 13 to perform circular motion. Since the gear 151 is engaged with the ring gear 14, the gear 151 will also rotate at this time, driving the second rotating rod 15 to rotate, driving the driving wheel 16 to rotate, driving the driven wheel 17 to rotate, and then driving the first rotating rod 12 to rotate, driving the grinding roller 13 to rotate, thereby grinding the tire mold.

[0053] During the grinding process, the water pump is started to pump water into the nozzle 27 through the water inlet pipe 28. The nozzle 27 will spray the water onto the grinding area of ​​the grinding roller 13 and the tire mold, thereby effectively cooling the area and preventing the grinding roller 13 and the tire mold from being easily damaged due to high temperature. The sprayed water can also play a certain role in reducing dust.

[0054] The rotation of the rotating shaft 5 will synchronously drive the cam 421 to rotate, and with the cooperation of the second spring 42, it will drive the T-bar 41 to move back and forth, drive the sliding plug 40 to slide back and forth, and generate suction force, so that the dust generated during the grinding process will be sucked into the dust removal box 37 through the dust suction hole 36 and the dust suction pipe 39, and then the dust will be discharged to the external collection box through the dust exhaust pipe 38, thereby preventing the dust generated during the grinding process from flying into the air, which is easy to be inhaled by the surrounding workers and enter the body, causing harm to the workers' health.

[0055] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
