Description

Technical Field

[0001] This utility model belongs to the technical field of process conveying equipment, and in particular relates to a rubber tire synchronous conveying device. Background Technology

[0002] As a modern means of transportation, automobiles have become an essential part of daily life. Tires are a crucial component of automobiles, and their quality directly affects the vehicle's safety and comfort. In the tire production process, transferring and conveying tires according to different technological requirements is a vital step.

[0003] Currently, most existing belt conveyors are traditional belt or chain structures, especially those used for loading and unloading in warehouses. These belt conveyors occupy a large area and have limited functionality, only capable of linear conveying at a fixed angle. For conveying at other angles, the conveying equipment needs to be modified. Since the rubber tire grading process requires adjusting the conveying angle according to production process requirements and connecting with conveyors going in different directions, fixed-angle process conveyors cannot meet the requirements. Modification is time-consuming, labor-intensive, and inconvenient for production users to operate during normal processes.

[0004] Chinese invention patent application number 201310054713.1 discloses an angle-adjustable inclined belt conveyor for an automated tire production line. It includes a head power mechanism, a middle rotating mechanism, a tail roller, a machine body, and a belt. The head power mechanism, middle rotating mechanism, and tail roller are connected sequentially via the belt. The machine body is inclined, with the middle rotating mechanism and tail roller installed at both ends of the inclined surface. The middle rotating mechanism drives the machine body to rotate, allowing for adjustable angle between the inclined surface and the ground. The drawback of this structure is that the belt inclination adjustment has a limit. To ensure sufficient friction, the adjustment of the conveying angle is restricted. To maintain the height at one end of the conveyor, the length of the conveyor limits the space between the other end and other process equipment. Space constraints make it difficult to install other conveying devices, affecting process continuity. Conventional belt conveyors are driven by the friction of the rollers, which can lead to slippage. In severe cases, this can cause tire congestion and affect the accuracy of tire transmission. Therefore, there is an urgent need to design a new type of conveying device to solve the above problems, achieve connection with receiving devices at different heights, improve transmission accuracy, and avoid belt slippage. Utility Model Content

[0005] The purpose of this invention is to provide a synchronous conveying device for rubber tires, which overcomes the shortcomings of the prior art. By using two synchronous belts to form the tire conveying path, it adapts to the application scenarios of angle changes when connecting with receiving devices of different heights in the existing rubber tire production process, and can improve the conveying accuracy and avoid slippage.

[0006] To achieve the above objectives, this utility model employs the following technical solution: A rubber tire synchronous conveying device includes a frame, a conveying boom, and a driver. The conveying boom includes two parallel arms, the base of which is connected to a main shaft. The main shaft is connected to the frame via bearing seats. The driver is fixed between the frame and the conveying boom. The driver controls the conveying boom to rotate around the main shaft, corresponding to two conveying directions: high and low. The base of the two arms is provided with a drive wheel, which is connected to the main shaft via a tensioning sleeve. The middle of the arms is connected via a crossbeam, the bottom of which is hinged to the end of the driver. The tip of the arms is provided with a driven wheel. A synchronous belt is wound between the drive wheel, the arms, and the driven wheel. The axle of the driven wheel is connected to a fixed plate, which is bolted to one side of the arms. The main shaft is connected to a conveying motor via a chain drive pair.

[0007] Furthermore, the actuator is any one of a hydraulic cylinder, a pneumatic cylinder, or an electric actuator.

[0008] Furthermore, the inner layer of the synchronous belt is a steel wire or glass fiber webbing, and the surface is covered with a polyurethane or neoprene rubber wear-resistant layer. The inner circumference of the synchronous belt is made into a tooth shape to mesh with the toothed driving pulley and driven pulley.

[0009] Furthermore, the width of the synchronous belt is 40-100mm, and the distance between the two arms is 300-500mm.

[0010] Furthermore, the main shaft section containing the two drive wheels is provided with drive wheel bearing seats, and the diameter of the main shaft section is larger than the diameter of other parts of the main shaft.

[0011] Furthermore, the transmission motor is a cycloidal pinwheel reducer with a reduction ratio of any one of 9, 11, 17, or 23.

[0012] Furthermore, the number of crossbeams is two or three, and they are evenly or unevenly arranged along the arm and length direction.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By using two parallel synchronous belts to form the tire conveying path, it can adapt to the application scenarios of angle changes when connecting with receiving devices of different heights in the existing rubber tire production process. The synchronous belt has strong stability and is minimally affected by angle changes in the conveying direction. The connecting teeth between the synchronous belt and the pulley can improve the transmission accuracy, prevent belt slippage, ensure the stability of the transmission process, and prevent production accidents and safety problems such as material falling due to slippage. This utility model has many advantages such as light weight, anti-slippage, smooth transmission and quiet operation. Attached Figure Description

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0018] See Figure 1-3This is a schematic diagram of an embodiment of the synchronous conveying device for rubber tires of this utility model. It includes a frame 1, a conveying arm 2, and a driver 3. The conveying arm 2 includes two parallel arms 4. The roots of the two arms 4 are connected to a main shaft 5. The main shaft 5 is connected to the frame 1 through a bearing seat 6. The driver 3 is fixed between the frame 1 and the conveying arm 2. The driver 3 controls the conveying arm 2 to rotate around the main shaft 5, corresponding to two conveying directions: high and low. The roots of the two arms 4 are provided with driving wheels 7, which are connected to the main shaft 5 through a tensioning sleeve 16. The middle part of the arms 4 is connected through a crossbeam 9. The bottom of the crossbeam 9 is hinged to the end of the driver 3. The tip of the arms 4 is provided with a driven wheel 8. A synchronous belt 10 is wound between the driving wheel 7, the arms 4, and the driven wheel 8. The axle of the driven wheel 8 is connected to a fixed plate 11. The fixed plate 11 is connected to one side of the arms 4 by bolts. The main shaft 5 is connected to a conveying motor 13 through a chain drive pair 12. The main shaft section 14 where the two drive wheels 7 are located is provided with drive wheel bearing seats 15. The diameter of the main shaft section 14 is larger than the diameter of other parts of the main shaft 5. The drive wheel bearing seats 15 can provide more stable support for the drive wheels 7.

[0019] An expansion sleeve (also known as an expansion sleeve) is a keyless connection device that generates a huge clamping force between the shaft and the hub through the axial force of high-strength bolts. It transmits torque, axial force or combined load by relying on friction. It is widely used in heavy machinery, wind power generation and other fields, and has advantages such as easy installation and overload protection.

[0020] In the embodiments, the actuator 3 can be any of a hydraulic cylinder, a pneumatic cylinder, or an electric actuator, with a pneumatic cylinder being preferred. Pneumatic systems have lower investment and maintenance costs and less environmental impact.

[0021] The inner layer of the synchronous belt 10 is made of steel wire or fiberglass webbing, and the surface is covered with a wear-resistant layer of polyurethane or neoprene rubber. The inner circumference of the synchronous belt 10 is toothed to mesh with the toothed driving pulley 7 and driven pulley 8. The width of the synchronous belt 10 is 40-100mm, preferably 60mm. The distance between the two arms 4 is 300-500mm, preferably 350mm. This model is suitable for various small and medium-sized wheel and tire production lines. The transmission motor 13 is a cycloidal pinwheel reducer with a reduction ratio of 9, 11, 17, or 23, selected according to the speed requirements of the production line.

[0022] The number of crossbeams 9 is two or three, and they are evenly or unevenly arranged along the boom 4 and the length direction. In this embodiment, there are two crossbeams, one of which is hinged to the driver, and the other only serves as a connection to enhance the strength of the conveyor boom 2.

[0023] In use, this embodiment of the invention first aligns the exit height of the conveyor boom 2 with the corresponding production line conveyor equipment according to the production process requirements. Then, the conveyor motor 13 is turned on, and the synchronous belt 10 begins to circulate around the drive wheel 7, boom 4, and driven wheel 8. The boom 4 provides support, preventing unevenness of the synchronous belt and ensuring smooth movement of the tires on the synchronous belt 10. When the conveyor motor 13 rotates in the reverse direction, the synchronous belt 10 moves in the reverse direction, thus determining the flow direction of materials on the production line and meeting the requirements of the production process. Compared with existing roller conveying methods, this embodiment of the invention has many advantages such as light weight, anti-slip, smooth conveying, and quiet operation.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
