Description

Technical Field

[0001] This utility model belongs to the field of tire processing technology, and in particular relates to a conveying device for coated tires. Background Technology

[0002] With the rise of new energy vehicles, spare tires have been eliminated to accommodate more battery storage space. Therefore, automakers urgently need self-sealing tires. Self-sealing tires require an internal sealant coating process; currently, tires with sealant applied require manual handling and must cool down before transport, which is time-consuming and takes up space. Otherwise, the freshly applied sealant is hot and will creep under gravity, easily causing uneven sealant thickness and affecting tire dynamic balance. Utility Model Content

[0003] This invention provides a conveying device for coated tires, which can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] A conveying device for coated tires includes a frame, an inlet platform, a conveying assembly, an outlet platform, a back roller rotating assembly, a tire ejection assembly, and a proximity sensor. The inlet platform and the outlet platform are located on the vertical sides at both ends of the frame, and the conveying assembly connects the inlet platform and the outlet platform. The back roller rotating assembly is located at the end of the conveying assembly, and the tire ejection assembly is located below the conveying assembly, corresponding to the outlet platform. The proximity sensor is located on the back roller rotating assembly and faces the tire on the conveying assembly. The conveying assembly includes a bearing seat, conveying rollers, and a motor. The bearing seat is located at both ends of the frame. There are two conveying rollers with an included angle of 0.21°-0.26° and a small distance between their inlet ends. The height difference between the front and rear ends of the two conveying rollers is 20mm-20.5mm, with the inlet end being higher. The motor is fixed to the frame and is linked to the two conveying rollers.

[0006] As a further improvement, the two conveyor rollers are 5.7m ± 100mm long, have an included angle of 0.21°, and a height difference of 20mm.

[0007] As a further improvement, the conveying rollers between the bearing seats are provided with roller assemblies, which are arranged in a "V" shape on both sides of the conveying rollers, and at least one set of roller assemblies is provided at intervals.

[0008] As a further improvement, limit switches are provided on both sides of the two conveyor rollers. The generator and receiver of the limit switches are respectively located on the frame at both ends of the two conveyor rollers, and the line connecting the generator and receiver is parallel to the corresponding conveyor roller.

[0009] As a further improvement, the back roller rotating assembly is provided with a mounting frame, a plurality of back rollers and back roller cylinders. The lower side of the mounting frame is hinged to the machine frame, the back rollers are arranged radially on the mounting frame, and the back roller cylinders are hinged to the machine frame and connected to the mounting frame.

[0010] As a further improvement, the tire ejection assembly is provided with a tire ejection cylinder, an mounting arm and a push plate. The tire ejection cylinder is hinged to the frame, the mounting arm is "L" shaped, one end of the "L" shaped mounting arm is hinged to the frame and the middle of the corresponding side of the mounting arm is connected to the tire ejection cylinder, and the push plate is connected to the other end of the "L" shaped mounting arm.

[0011] As a further improvement, rollers are arranged on the push plate; the angle between the push plate and the "L"-shaped mounting arm is 15°-45°, and the horizontal tilt angle of the push plate is 20°-30° when the rollers contact the tire.

[0012] As a further improvement, each end of the frame is provided with an inlet platform and an outlet platform. The inlet platform is a feed plate that is hinged to the frame and can be folded for storage. The outlet platform is an outlet channel with vertical discharge rollers on both sides. The number of the tire pushing assemblies is the same as the number of outlet platforms.

[0013] As a further improvement, the frame is equipped with protective doors and covers.

[0014] The beneficial effects of this invention are as follows: This device uses a conveying assembly consisting of two conveying rollers to transport tires coated with sealant to the next process. During the conveying process, the tires are rotated, and the internal sealant is dispersed and adheres to the inner wall of the tire through a certain centrifugal force, enhancing the coating effect. The rotation also accelerates heat dissipation. Finally, the tires are transferred from the conveying rollers to the outlet platform through the tire exit assembly, ensuring smooth connection with the upstream and downstream processes. This facilitates the construction of automated production lines, improves overall production efficiency, and enhances production quality. Attached Figure Description

[0026] Reference Figure 1-5 As shown, a conveying device for coated tires includes a frame 1, an inlet platform 2, a conveying assembly 3, an outlet platform 4, a back roller rotating assembly 5, a tire ejection assembly 6, and a proximity sensor 7. The inlet platform 2 and the outlet platform 4 are located on the vertical sides at both ends of the frame 1. The conveying assembly 3 connects the inlet platform 2 and the outlet platform 4. The back roller rotating assembly 5 is located at the end of the conveying assembly 3. The tire ejection assembly 6 is located below the conveying assembly 3, corresponding to the outlet platform 4. The proximity sensor 7 is located on the back roller rotating assembly 5 and faces the tire on the conveying assembly 3. The conveying assembly 3 includes a bearing 31, conveying rollers 32, and a motor 33. The bearing 31 is located at both ends of the frame 1. There are two conveying rollers 32 with an included angle of 0.21°-0.26° and a small distance between their inlet ends. The height difference between the front and rear ends of the two conveying rollers 32 is 20mm-20.5mm, with the inlet end being higher. The motor 33 is fixed on the frame 1 and is linked with the two conveying rollers 32.

[0027] The tire rolls from the inlet platform 2 onto the conveyor assembly 3. The angle between the two conveyor rollers 32 (smaller at the top and larger at the bottom) and the drop design (higher at the top and lower at the bottom) causes the tire to tend to move downstream after falling onto the conveyor rollers 32. The motor 33 drives the conveyor rollers 32 to roll, and the conveyor rollers 32 drive the tire to rotate. Under the action of centrifugal force, the sealant inside the tire spreads to the inner wall of the tire, making the adhesive evenly dispersed and tightly adhered. When the tire moves to the back roller rotating assembly 5, the proximity sensor 7 senses the tire and starts timing. It continues to rotate and dissipate heat for a certain period of time, which can be set to 60 seconds. When the preset time is reached, the tire ejection assembly 6 is activated, pushing the tire out of the conveyor assembly 3. The tire enters the outlet platform 4 and is conveyed to the next process.

[0028] If the angle between the two conveyor rollers 32 is too large, the center of gravity will be too low, making it impossible to match tires of various sizes and specifications, resulting in difficulty in moving or kicking them out. If it is too small, the center of gravity will be too high, and the tires will easily detach from the rollers during rotation. If the drop is too large, the tires will move too fast, and if it is too small, the tires will move too slowly, affecting the stability of movement on the one hand, and the uniformity of the internal adhesive on the other hand.

[0029] Furthermore, the two conveying rollers 32 have a length of 5.7m ± 100mm, an included angle of 0.21°, and a height difference of 20mm.

[0030] If the length of the conveyor roller 32 is too small, it will affect the installation space of the parts, and the remaining space will also be smaller, making installation, debugging and maintenance difficult; if it is too large, it will affect the installation space of the equipment. The overall length of the equipment increases the space requirements, the weight of the conveyor roller will also increase the power of the motor, and the cost will increase.

[0031] The design of this length, angle, and drop allows the tire to transfer power stably to the other end.

[0032] Furthermore, the conveying rollers 32 between the bearing seats 31 are provided with roller assemblies 34, which are arranged in a "V" shape on both sides of the conveying rollers 32, and at least one set of roller assemblies 34 is provided at intervals.

[0033] The roller assembly 34 supports the conveyor roller 32, preventing it from bending and deforming due to its excessive length. The "V"-shaped arrangement of the roller assembly 34 effectively avoids the movement of the tire.

[0034] Furthermore, limit switches 35 are provided on both sides of the two conveying rollers 32. The generator and receiver of the limit switches 35 are respectively provided on the frame 1 at both ends of the two conveying rollers 32, and the line connecting the generator and receiver is parallel to the corresponding conveying roller 32.

[0035] Limit sensor switch 35 prevents the tire from popping out from both sides of the conveyor roller 32, which could cause the tire to be pinched and damaged. When the limit sensor switch detects that the tire has popped out, the motor 33 stops working.

[0036] Furthermore, the back roller rotating assembly 5 is provided with a mounting frame 51, a plurality of back rollers 52 and a back roller cylinder 53. The lower side of the mounting frame 51 is hinged to the frame 1. The back rollers 52 are arranged radially on the mounting frame 51. The back roller cylinder 53 is hinged to the frame 1 and connected to the mounting frame 51.

[0037] When the back roller 52 is in contact with the tire, it enables the tire to roll more smoothly; the back roller cylinder 53 extends forward in its initial state, so that the tire's state at the end of the back roller rotating assembly 5 is consistent with the exit platform 4, avoiding collision with the exit platform 4 when the tire is pushed out; when the tire is pushed out, the back roller cylinder 53 moves at the same time to retract the mounting frame 51 to avoid the tire's exit direction.

[0038] Furthermore, the tire ejection assembly 6 is provided with a tire ejection cylinder 61, a mounting arm 62 and a push plate 63. The tire ejection cylinder 61 is hinged to the frame 1. The mounting arm 62 is "L" shaped. One end of the "L" shaped mounting arm 62 is hinged to the frame 1 and the middle part of the corresponding side of the mounting arm 62 is connected to the tire ejection cylinder 61. The push plate 63 is connected to the other end of the "L" shaped mounting arm 62.

[0039] The tire ejection cylinder 61 pushes the push plate 63 upward from below, and the push plate 63 pushes the tire towards the exit direction, completing the tire ejection.

[0040] Furthermore, rollers 64 are arranged on the push plate 63; the angle between the push plate 63 and the "L"-shaped mounting arm 62 is 15°-45°, and the horizontal tilt angle of the push plate 63 is 20°-30° when the rollers 64 are in contact with the tire.

[0041] This angle allows the tire to be accurately pushed onto the exit platform 4.

[0042] Furthermore, each of the two sides of the frame 1 is provided with an inlet platform 2 and an outlet platform 4. The inlet platform 2 is provided with a feed plate that is hinged to the frame 1 and can be folded for storage. The outlet platform 4 is an outlet channel, and vertical discharge rollers 41 are provided on both sides of the outlet channel. The number of the tire pushing components is the same as the number of outlet platforms 4.

[0043] By setting up an import platform 2 and an export platform 4, operators can simultaneously operate two adjacent devices, improving work efficiency.

[0044] Furthermore, the frame 1 is provided with a protective door 11 and a protective cover 12.

[0045] Protective doors 11 are installed at the inlet platform 2 and outlet platform 4, as well as at other reserved workstations and inspection equipment that need to be opened. Protective covers 12 are installed at other locations on the frame 1 to protect the internal equipment.

[0046] During operation, the conveyor roller 32 assembly starts, and the tire enters the equipment from the inlet platform 2;

[0047] The tire rotates at a constant speed from the upstream end to the downstream end via the conveyor roller 32. After reaching the downstream end, it comes into close contact with the back roller rotating assembly 5. Limit sensor switches 35 are set on both sides of the conveyor roller 32 from the upstream end to the downstream end. If the tire leaves the conveyor roller 32 during the conveying process, the limit sensor switch 35 on the corresponding side will be triggered, and the motor 33 will stop automatically. The two 5.7m long conveyor rollers 32 form an included angle of 0.21°, with the upstream end smaller and the downstream end larger. The height difference between the front and rear fixed reference surfaces of the two conveyor rollers 32 is 20mm, with the upstream end higher and the downstream end lower.

[0048] Upon reaching the downstream end, the proximity sensor 7 receives a signal and begins timing for 60 seconds, while the tire continues to rotate to dissipate heat.

[0049] When the countdown ends, the back roller cylinder 53 connected to the back roller rotating assembly 5 retracts, and the tire ejection cylinder 61 of the tire ejection assembly 6 extends to drive the push plate 63 to rise and eject the tire. After completion, the back roller cylinder 53 connected to the back roller rotating assembly 5 extends back to its original position, the tire ejection cylinder 61 retracts, the push plate 63 returns to its original position, and the tire enters the tire conveying system through the outlet platform 4.

[0050] During the conveying process, the tire will have an inertia to move downstream as it rotates on the conveyor roller 32. The back roller rotating assembly 5 is connected to the back roller cylinder 53 and kept in an extended state. This is to keep the tire relatively centered on the outlet platform 4 while the push plate 63 is raised, so that the tire can stably pass through the outlet platform 4 and enter the tire conveying system.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
