DETAILED DESCRIPTION

[0036] This application provides an automatic control device for heavy-duty desert tire production, please refer toFigures 1-9 : It includes a workbench 1 for supporting a tire 2, and the center of the workbench 1 is the centering position;

[0037] An execution component 3, which contacts the tire 2 and moves the tire 2 towards the center of the workbench 1 to achieve centering of the tire 2;

[0038] A power component 4, which provides a power source for the execution component 3 to center the tire 2; drives the execution component 3 to move towards the center position of the workbench 1;

[0039] A transmission component 5, and the power component 4 transmits power to the execution component 3 through the transmission component 5.

[0040] Specifically, in actual application, this device is set at the end of the tire production line, and there is no need for the tire 2 to move on the production line subsequently, such as at the position where palletizing is required. At this time, a manipulator is needed to move the tire 2 to the palletizing position, and a centering operation needs to be performed on the tire 2 before that; the conveyor belt belongs to the prior art and will not be described in detail, and no label is given in the figure;

[0041] Under the action of inertia, the tire 2 moves to the upper surface of the workbench 1 through the conveyor belt. At this time, the position of the tire cover 2 is not centered. First, control the power component 4 to work. Through the transmission of the transmission component 5, the power component 4 can drive the execution component 3 to move. The execution component 3 is arranged at the four corners of the workbench 1, and the execution component 3 can move the center of the tire 2 to align with the center of the workbench 1, realizing automatic alignment and ultimately achieving the purpose of centering;

[0042] The position where the execution component 3 contacts the tire 2 can be set to be anti-slip to reduce the probability of the execution component 3 being disengaged; alternatively, the position where the execution component 3 contacts the tire 2 can be set to be a roller to reduce the friction generated by the movement of the tire 2.

[0043] For the first embodiment of the execution component 3, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 6 , the execution component 3 includes sliding grooves 31 opened on the surface of the workbench 1. There are multiple sliding grooves 31, and the extending direction of the sliding grooves 31 points to the center of the workbench 1. A sliding block 32 that is in clearance fit with the sliding grooves 31 is arranged in the sliding grooves 31. An internal thread tube 33 is arranged on the upper surface of the sliding block 32. A screw rod 34 is arranged in the internal thread tube 33. One end of the screw rod 34 extending out of the internal thread tube 33 is provided with a contact head 35, and an anti-slip pattern 36 is arranged on the side surface of the contact head 35. A nut 311 is arranged on the screw rod 34.

[0044] Specifically, in practical applications, the extension line of the chute 31 passes through the center of the workbench 1. When the sliding block 32 slides along the chute 31, it can drive the execution component 3 to move accordingly. Through the settings of the abutting head 35 and the anti-slip lines 36, the center of the tire 2 can be moved to the position in the workbench 1, achieving the purpose of centering. By rotating the screw 34, the distance between the abutting head 35 and the internal thread tube 33 can be adjusted, thereby centering tires 2 with different diameters. The screw 34 can be positioned by tightening the nut 311 to prevent the screw 34 from wobbling back and forth;

[0045] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8 ,the transmission component 5 includes a rectangular ring 51 installed below the sliding block 32. A rack 52 is installed inside the rectangular ring 51. At the four corners of the lower surface of the workbench 1, first bearings 53 are installed. The inner ring of the first bearing 53 is installed with a rotating shaft 54. A first gear 55 meshing with the rack 52 is installed on the rotating shaft 54. A second toothed belt pulley 56 is also installed on the rotating shaft 54. A toothed belt 57 in interference fit with the second toothed belt pulley 56 is installed on the second toothed belt pulley 56; A pressure roller 59 is also installed on one side of the workbench 1.

[0046] Specifically, in practical applications, when the power component 4 works, it can drive the toothed belt 57 to move. While the toothed belt 57 moves, it drives the second toothed belt pulley 56, the rotating shaft 54, and the first gear 55 to rotate synchronously. Through the function of the first bearing 53, the rotating shaft 54 rotates stably, changing the relative position between the rack 52 and the rectangular ring 51. When multiple first gears 55 rotate in the same direction, they can drive multiple sliding blocks 32 to move towards the center position of the workbench 1. The pressure roller 59 can press the toothed belt 57 on the output end of the power component 4 to avoid slipping.

[0047] For the first embodiment of the power component 4, refer to Figure 1 and Figure 2 ,the height of the workbench 1 does not change. The power component 4 includes a drive motor 41 installed on the workbench 1. The drive motor 41 is fixedly connected to the workbench 1 and its rotating end faces downward. A third toothed belt pulley 42 is installed on the rotating end of the drive motor 41. The third toothed belt pulley 42 meshes with the toothed belt 57.

[0048] Specifically, in practical applications, the rotating end of the drive motor 41 directly drives the third toothed belt pulley 42 to rotate, and the third toothed belt pulley 42 directly drives the toothed belt 57 to move, thereby achieving the purpose of centering.

[0049] For the second embodiment of the power component 4, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, when the height of the workbench 1 changes, the power assembly 4 further includes a horizontal bearing 43 installed on the workbench 1. The inner ring of the horizontal bearing 43 is equipped with a rotating tube 44. The upper end of the rotating tube 44 is installed with a fourth toothed belt pulley 45, and the fourth toothed belt pulley 45 meshes with the toothed belt 57;

[0050] A base 46 is provided below the workbench 1. A column 47 is provided on the base 46. The column 47 passes through the rotating tube 44. A spiral groove 48 is formed on the column 47. A block 49 that is in clearance fit with the spiral groove 48 is installed on the inner ring of the rotating tube 44;

[0051] Limit rings 410 are fixedly installed at the four corners of the workbench 1. The limit rings 410 penetrate the workbench 1. A limit post 411 is installed on the base 46. The limit post 411 passes through the limit ring 410. A tension spring 412 is installed between the upper end of the limit post 411 and the limit ring 410. A positioning block 413 is installed on the limit post 411.

[0052] Specifically, in actual application, when the height of the workbench 1 changes, when the workbench 1 is in the highest position, the elastic force generated by the tension spring 412 is equal to the gravity of the workbench 1 and other parts connected to the workbench 1. At this time, it can just maintain the height of the workbench 1. After the tire 2 moves onto the workbench 1, the workbench 1 is pressed downward by the gravity of the tire 2; when the workbench 1 moves, it drives the horizontal bearing 43, the block 49, the rotating tube 44 and the fourth toothed belt pulley 45 to move downward. At this time, the column 47 and the spiral groove 48 are fixed. By using the relative movement between the spiral groove 48 and the block 49, the block 49 can be driven to rotate. The block 49 drives the rotating tube 44 and the fourth toothed belt pulley 45 to rotate. Through the action of the horizontal bearing 43, the rotating tube 44 rotates stably. The fourth toothed belt pulley 45 can drive the toothed belt 57 to move, and finally achieve the purpose of centering by relying on the gravity of the tire 2;

[0053] When the tire 2 is removed from the outside, the workbench 1 can be in a reset state through the elasticity of the tension spring 412; through the action of the limit post 411 and the limit ring 410, the workbench 1 slides stably.

[0054] For the second embodiment of the actuating assembly 3, refer to Figure 5 , when the height of the workbench 1 changes, the actuating assembly 3 further includes a round hole 37 opened at the center of the workbench 1. A vertical rod 38 is installed at the center of the base 46. A guide plate 39 is installed at the upper end of the vertical rod 38. The guide plate 39 is hinged to the vertical rod 38. A telescopic rod 310 is installed between the lower end of the guide plate 39 and the vertical rod 38.

[0055] Specifically in practical applications, after the tire 2 moves onto the workbench 1, the workbench 1 is pressed downward by the gravity of the tire 2. While the tire 2 moves downward, the guide plate 39 contacts the inner wall of the tire 2. As the tire 2 continues to move, the guide plate 39 moves the tire 2 to the center position of the workbench 1. The inclination of the guide plate 39 is adjusted by the telescopic rod 310 to facilitate the movement of the tire 2. Through this embodiment, the execution component 3, the power component 4, and the transmission component 5 can be integrated into one body.

[0056] Referring to Figure 8 , a linear motor 461 is installed on the base 46. The telescopic end of the linear motor 461 interferes with the limit ring 410, and an infrared sensor 462 is installed on the workbench 1.

[0057] Specifically in practical applications, when all the tires 2 move onto the workbench 1, the tires 2 will block the infrared rays emitted by the infrared sensor 462. At this time, the linear motor 461 is controlled to shorten, and the telescopic end of the linear motor 461 moves away from the lower end of the workbench 1. At this time, the workbench 1 is in a state where it can move downward, making the overall device operate more stably.

[0058] Referring to Figure Figure 3 and Figure 4 , a thimble spring 463 is installed on the base 46.

[0059] Specifically in practical applications, through the action of the thimble spring 463, the workbench 1 can be buffered.

[0060] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , universal balls 11 are installed on the workbench 1, and a baffle 111 is provided on one side of the workbench 1.

[0061] Specifically in practical applications, through the action of the universal balls 11, the friction between the tire 2 and the workbench 1 can be greatly reduced, facilitating the sliding of the tire 2 on the workbench 1.

[0062] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the surface of the guide plate 39 is smoothed.

[0063] Specifically in practical applications, smoothing the surface of the guide plate 39 can reduce the friction with the tire 2;

[0064] Referring to Figure 7 and Figure 9 , the toothed belt 57 can be set to have teeth on one side or both sides, and the second toothed belt pulley 56 can be set to have teeth or no teeth;

[0065] Figure 7 In the second toothed pulley 56, there are no teeth, and it is driven by the frictional force with the toothed belt 57. The disadvantage is that it is easy to slip, but it can prevent overload;

[0066] Figure 9 In the second toothed pulley 56, there are teeth, and it is driven by the meshing force with the toothed belt 57, and it is not easy to slip. The electrical appliance in this application is electrically connected to an external controller.
