Description

Technical Field

[0001] This invention relates to the field of synchronous pitch change technology, specifically to a dual driven wheel synchronous pitch change transfer mechanism. Background Technology

[0002] Synchronous operation of two wheels is a common mechanical motion method in industrial production and is widely used in many fields. In practical applications, this synchronous variable-pitch transfer mechanism with two driven wheels can be widely used in automated production lines, logistics conveying systems and other fields. On automated production lines, it can ensure the accurate transfer of materials, improve production efficiency and product quality. In logistics conveying systems, the distance between the driven wheels can be flexibly adjusted according to the size and weight of different goods to achieve efficient goods transportation.

[0003] Prior art (Chinese Patent No. CN108639703A, published on 2018-10-12) discloses a transport and connection mechanism for a production line, including a base, at least one upright plate mounted on the base, a synchronous drive device, and a synchronous transmission device mounted on the upright plate. The synchronous transmission device includes a driven wheel mounted on the upright plate and a first synchronous pulley group and a second synchronous pulley group respectively located on both sides of the driven wheel. The synchronous drive device includes a main synchronous pulley that is driven by a synchronous shaft and is connected to the driven wheel. The main synchronous pulley drives the driven wheel to rotate through the synchronous shaft, thereby driving the first synchronous pulley group and the second synchronous pulley group to rotate, realizing synchronous operation between production line groups with high synchronization accuracy, and ensuring smooth transition of workpieces between production line groups. It can drive a production line group to operate independently, or multiple upright plates can be set according to production needs and corresponding synchronous transmission devices can be added to the upright plates to achieve the purpose of driving multiple production line groups to operate simultaneously, making it highly versatile.

[0004] Although existing technology can drive two sets of synchronous pulleys to rotate simultaneously via belts, the rotation still involves one synchronous pulley rotating first and then driving the other synchronous pulley to rotate via belt. This transmission method is prone to transmission delay and synchronization error, making it difficult for the rotation speed and angle of the two driven pulleys to be precisely consistent. Especially under high-speed operation or frequent start-stop conditions, the synchronization performance will further deteriorate.

[0005] Therefore, we propose a dual driven wheel synchronous variable pitch transfer mechanism to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a dual driven wheel synchronous variable pitch transfer mechanism to solve the problem mentioned in the background art. Currently, the rotation of the mechanism is still achieved by rotating one synchronous wheel and then driving another synchronous wheel through a belt. This transmission method is prone to transmission delay and synchronization error, making it difficult for the rotation speed and angle of the two sets of driven wheels to be precisely consistent. Especially under high-speed operation or frequent start-stop conditions, the synchronization performance will be further reduced.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dual driven wheel synchronous variable pitch transfer mechanism, comprising a device body, on which two sets of rotating rollers are rotatably mounted, and driven wheel bodies are fixedly connected to the outer side of the rotating rollers, and a linkage belt is sleeved on the outer side of the driven wheel bodies. A synchronization mechanism is provided between the driven wheel bodies and the device body, and the synchronization mechanism achieves synchronous operation of the two sets of driven wheel bodies by driving the rotation of the rollers through the motor contained therein. An auxiliary cavity is provided inside the driven wheel body, and a friction mechanism is provided inside the auxiliary cavity. The friction mechanism drives the abutment column to move outward by the centrifugal force generated when the driven wheel body rotates, increasing the friction between the abutment column and the linkage belt, thereby improving the stability of the rotating roller operation.

[0008] Preferably, the synchronization mechanism includes a motor drive roller, which is mounted on the equipment body and positioned at the middle position above the two sets of driven wheel bodies. The linkage belt is sleeved on the outside of the motor drive roller, and the motor drive roller drives the two sets of driven wheel bodies to rotate through the linkage belt.

[0009] Preferably, the device body is provided with a movable and fixed adjustment plate, and a limit roller is rotatably provided on the adjustment plate. Two sets of limit rollers are symmetrically distributed about the center point of the motor drive roller, and the outer side of the limit roller is in contact with the linkage belt.

[0010] Preferably, the auxiliary cavity is arranged in a "T" shape in cross-section. A connecting flexible rod is fixedly connected to the center of the auxiliary cavity, and an abutting ball is fixedly connected to the outer end of the connecting flexible rod. The highest point of the outer end of the abutting ball is higher than the highest point of the outer surface of the driven wheel body. The connecting flexible rods are arranged in a circular array about the center point of the driven wheel body. When the abutting ball abuts against the linkage belt, the connecting flexible rod is in a bent state.

[0011] Preferably, the friction mechanism includes an adjustment box, which is symmetrically distributed about the center point of the connecting flexible rod. A contact post is slidably connected to the upper side of the adjustment box. A storage groove is provided on the driven wheel body, and the contact post is slidably disposed inside the storage groove. A connecting plate is fixedly connected to the inner end of the contact post, and the interior of the connecting plate is slidably connected inside the adjustment box.

[0012] Preferably, the adjustment box is slidably provided with an inclined block on its side, and the inclined block is located above the connecting plate. The side of the connecting plate is in contact with the inclined side of the inclined block, and a docking rod is fixedly connected to the outside of the inclined block.

[0013] Preferably, the driven wheel body has an air supply cavity inside, and the air supply cavity is positioned corresponding to the adjustment box. The outer side of the tilting block is slidably disposed inside the air supply cavity, and the side of the tilting block contacts the inner wall of the air supply cavity. The tilting block connecting plate and the air supply cavity form an elastic structure.

[0014] Preferably, a return spring is fixedly connected between the side of the inclined block and the inner wall of the air supply chamber, an exhaust channel is provided on the driven wheel body, the exhaust channel corresponds to the side of the linkage belt, and the exhaust channel is connected to the air supply chamber.

[0015] Preferably, the device body is fixedly connected with protrusions, and the protrusions are arranged in a ring array about the center point of the driven wheel body. The sides of the protrusions are arranged in an arc shape, and the outer end of the docking rod is fixedly connected with a contact plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) A motor-driven roller is provided. The motor-driven roller serves as the driving source. When the motor-driven roller rotates, it can synchronously drive the linkage belt to rotate. At this time, the linkage belt will drive the two sets of driven wheels connected to it to rotate synchronously, ensuring that the two sets of driven wheels can run at the same speed and direction, realizing the synchronous operation of the two driven wheels, and improving the stability and efficiency of the entire transfer mechanism.

[0018] (2) Limit rollers are provided on the side of the linkage belt. The linkage belt can be guided by the limit rollers to control the running trajectory of the linkage belt and prevent it from deviating or shaking, thereby ensuring the stability and reliability of the entire transfer mechanism during operation. By adjusting the position of the limit rollers, the tension of the linkage belt can also be adjusted to meet the usage requirements under different working conditions, further improving the flexibility and applicability of the transfer mechanism.

[0019] (3) During the rotation of the driven wheel body, the contact ball is higher than the highest point of the outer surface of the contact ball, and the contact ball will come into contact with the linkage belt. When the contact ball comes into contact with the linkage belt, the connecting soft rod is in a bent state. This elastic contact method can ensure sufficient contact with the linkage belt and avoid excessive wear caused by rigid contact, further improving the reliability and stability of the equipment. As the rotation speed of the driven wheel body increases, the connecting soft rod gradually bends under the action of centrifugal force, so that the contact ball applies continuous pressure to the linkage belt, thereby enhancing the friction between the linkage belt and the driven wheel body. At the same time, its friction automatically adjusts the contact strength according to the change of rotation speed, effectively preventing belt slippage.

[0020] (4) A friction mechanism is set inside the driven wheel body. When the driven wheel body rotates, the centrifugal force generated by the rotation of the driven wheel body will drive the abutment column to move outward. The outwardly moving abutment column will contact the linkage belt. Thus, during the operation of the driven wheel body, the driven wheel body will drive the contact plate to rotate synchronously. When the contact plate moves to the side of the protrusion, the protrusion abuts against the contact plate, causing the contact plate to drive the inclined block to move towards the inside of the adjustment box through the docking rod, thereby abutting the connecting plate, causing the connecting plate to move down, and driving the abutment column to reset. The abutment column moves back and forth through the action of the driven wheel body and the protrusion, further increasing the friction force on the linkage belt, improving the operation stability of the rotating roller, reducing the problem of poor operation caused by slippage, and extending the service life of the equipment.

[0021] (5) When the protrusion does not contact the contact plate, the tilt block is reset under the elastic force of the return spring. At this time, the tilt block can move along the inside of the air supply chamber and squeeze the gas inside the air supply chamber. The gas is discharged outward through the exhaust channel. The discharged gas directly acts on the side of the linkage belt, which can clean the linkage belt and blow away the dust and debris attached to the linkage belt. This prevents these impurities from affecting the friction between the linkage belt and the driven wheel body, ensuring good contact and transmission effect between the two. The discharge of gas can also reduce the temperature of the linkage belt to a certain extent. During long-term operation, the friction between the linkage belt and the driven wheel body will generate heat. Excessive temperature may cause the performance of the linkage belt to decline, or even cause aging, deformation and other problems. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: To ensure synchronous rotation between the two sets of driven wheel bodies 4, and to prevent one driven wheel body 4 from driving the other driven wheel body 4, as follows: Figure 1 - Figure 4The present invention provides the following technical solution: a dual driven wheel synchronous variable pitch transfer mechanism, wherein two sets of rotating rollers 20 are rotatably arranged on the equipment body 1, and driven wheel bodies 4 are fixedly connected to the outer side of the rotating rollers 20, and a linkage belt 5 is sleeved on the outer side of the driven wheel bodies 4. A synchronization mechanism is provided between the driven wheel bodies 4 and the equipment body 1. The synchronization mechanism realizes the synchronous operation of the two sets of driven wheel bodies 4 through the rotation of the motor drive roller 2 included therein. The synchronization mechanism includes a motor drive roller 2, which is arranged on the equipment body 1 and is located at the middle position above the two sets of driven wheel bodies 4. The linkage belt 5 is sleeved on the outer side of the motor drive roller 2. The motor drive roller 2 drives the two sets of driven wheel bodies 4 to rotate through the linkage belt 5. A movable and fixed adjusting plate 19 is provided on the equipment body 1, and a limiting roller 3 is rotatably arranged on the adjusting plate 19. Two sets of limiting rollers 3 are symmetrically distributed about the center point of the motor drive roller 2, and the outer side of the limiting roller 3 is in contact with the linkage belt 5.

[0034] When the motor-driven roller 2 is powered on and starts operating, the strong friction between its surface and the linkage belt 5 enables it to rotate synchronously. Simultaneously, the linkage belt 5, which is fitted onto two sets of driven pulley bodies 4, rotates itself, driving these two sets of driven pulley bodies 4 to rotate synchronously through friction. This utilizes the principle of belt drive, ensuring that the two sets of driven pulley bodies 4 rotate at exactly the same speed and direction, achieving precise synchronous operation of the two driven pulleys. To further optimize the operation of the linkage belt 5, limit rollers 3 are carefully installed on its sides. The contact between the limit rollers 3 and the linkage belt 5 effectively guides the belt, preventing it from slipping during operation. Even if there is deviation or swaying, the linkage belt 5 can maintain a stable operating state under the guidance of the limit roller 3, thus ensuring the smoothness and reliability of the entire transfer mechanism during operation. At the same time, the operator can precisely adjust the position of the limit roller 3 according to the actual working conditions through a simple adjustment device. When it is necessary to increase the tension of the linkage belt 5, the limit roller 3 is moved closer to the linkage belt 5 to make the belt subject to greater tension, thereby increasing the tension. Conversely, when it is necessary to decrease the tension, the limit roller 3 is moved away from the linkage belt 5. This allows the transfer mechanism to adapt to the transfer needs of materials of different weights and sizes, as well as the usage requirements of different working environments, further improving the flexibility and applicability of the transfer mechanism.

[0035] Example 2: To increase the friction between the drive belt 5 and the driven pulley 4, and to reduce the occurrence of misalignment and loosening of the drive belt 5, as follows: Figure 5 - Figure 8The present invention provides the following technical solution: a dual driven wheel synchronous variable pitch transfer mechanism, wherein an auxiliary cavity 10 is provided inside the driven wheel body 4, and a friction mechanism is provided inside the auxiliary cavity 10. The friction mechanism uses the centrifugal force generated when the driven wheel body 4 rotates to drive the abutment column 11 to move outward, increasing the friction between it and the linkage belt 5, thereby improving the operating stability of the rotating roller 20. The auxiliary cavity 10 is arranged in a "T" shape in cross-section. A connecting flexible rod 7 is fixedly connected to the center of the auxiliary cavity 10, and an abutment ball 6 is fixedly connected to the outer end of the connecting flexible rod 7. The highest point of the outer end of the abutment ball 6 is higher than the highest point of the outer surface of the driven wheel body 4. The connecting flexible rod 7 is arranged in a ring about the center point of the driven wheel body 4. The friction mechanism includes an adjustment box 9, which is symmetrically distributed about the center point of the connecting flexible rod 7. An abutment post 11 is slidably connected to the upper side of the adjustment box 9. A storage groove 21 is provided on the driven wheel body 4, and the abutment post 11 is slidably disposed inside the storage groove 21. A connecting plate 14 is fixedly connected to the inner end of the abutment post 11. The interior of the connecting plate 14 is slidably connected to the interior of the adjustment box 9. An inclined block 15 is slidably disposed on the side of the adjustment box 9. The inclined block 15 is located above the connecting plate 14, and the side of the connecting plate 14 is in contact with the inclined side of the inclined block 15. A docking rod 17 is fixedly connected to the outer side of the inclined block 15.

[0036] When the driven wheel body 4 starts to rotate, due to the relative motion between the linkage belt 5 and the driven wheel body 4, the abutting ball 6 will naturally come into contact with the linkage belt 5. At this time, the connecting flexible rod 7 exhibits a certain degree of bending due to its own elastic properties, ensuring sufficient contact between the abutting ball 6 and the linkage belt 5. Under the elastic support of the connecting flexible rod 7, the abutting ball 6 is tightly attached to the surface of the linkage belt 5, ensuring effective force transmission. This allows the power of the driven wheel body 4 to be stably transmitted through the linkage belt 5, absorbing and dispersing some of the impact force on the linkage belt 5, thereby greatly reducing the impact on the linkage belt. 5. Excessive wear caused by rigid contact further improves the reliability and stability of the equipment. As the rotational speed of the driven wheel body 4 gradually increases, the bending degree of the connecting flexible rod 7 will gradually intensify under the influence of centrifugal force. As the connecting flexible rod 7 bends, the contact ball 6 will apply a continuous and stable pressure to the linkage belt 5, which enhances the friction between the linkage belt 5 and the driven wheel body 4. When the rotational speed of the driven wheel body 4 increases, the bending degree of the connecting flexible rod 7 increases, the pressure applied by the contact ball 6 also increases, and the friction is correspondingly enhanced, which can effectively prevent belt slippage caused by excessive speed and excessive power.

[0037] When the driven wheel body 4 starts to rotate, the centrifugal force generated by the high-speed rotation of the driven wheel body 4 drives the abutment column 11 to move outward until it comes into close contact with the linkage belt 5. When the contact plate 12 moves to the side of the protrusion 8, the protrusion 8 applies a reverse abutment force to the contact plate 12 and transmits the force to the docking rod 17 through the contact plate 12. The tilting block 15 is located inside the adjustment box 9. When the tilting block 15 is pushed by the docking rod 17, it can move along the inner side of the adjustment box 9. When the tilting block 15 moves inward, it will abut against the connecting plate 14. The connecting plate 14 moves downward under the action of the abutment force of the tilting block 15. The downward movement of the connecting plate 14 directly acts on the abutment column 11. Under the action of the connecting plate 14, the abutment column 11 returns to the initial position along the original path, ready to receive the next centrifugal force drive. The abutment column 11 realizes the reciprocating movement, and the friction force on the linkage belt 5 is significantly increased, greatly reducing the problem of poor operation caused by slippage.

[0038] Example 3: During long-term operation, the linkage belt 5 will inevitably accumulate dust and debris, which will seriously affect the friction between the linkage belt 5 and the driven pulley body 4, leading to a decrease in transmission efficiency and even potentially causing belt slippage. To solve this problem, such as... Figure 6 - Figure 9 The present invention provides the following technical solution: a dual driven wheel synchronous variable pitch transfer mechanism, wherein the driven wheel body 4 has an air supply cavity 13 inside, and the air supply cavity 13 corresponds to the position of the adjustment box 9, and the outer side of the inclined block 15 is slidably disposed inside the air supply cavity 13, and the side of the inclined block 15 contacts the inner wall of the air supply cavity 13. The inclined block 15 and the air supply cavity 13 form an elastic structure through the connecting plate 14. A return spring 16 is fixedly connected between the side of the inclined block 15 and the inner wall of the air supply cavity 13. An exhaust channel 18 is provided on the driven wheel body 4, and the exhaust channel 18 corresponds to the side of the linkage belt 5. The exhaust channel 18 is connected to the air supply cavity 13. A protrusion 8 is fixedly connected on the device body 1, and the protrusion 8 is arranged in a ring array about the center point of the driven wheel body 4. The side of the protrusion 8 is arranged in an arc structure. A contact plate 12 is fixedly connected to the outer end of the connecting rod 17.

[0039] When the protrusion 8 no longer exerts a resisting force on the contact plate 12, the pushing force on the tilting block 15 generated by the contact plate 12 due to the contact with the protrusion 8 disappears. The return spring 16 releases its elastic potential energy instantaneously, converting it into the power to drive the tilting block 15 to reset. Driven by the elastic force of the return spring 16, the tilting block 15 begins to move smoothly and rapidly along the inside of the air supply cavity 13. As the tilting block 15 moves within the air supply cavity 13, it compresses the gas inside the air supply cavity 13. Under the push of the tilting block 15, the pressure of the gas inside the air supply cavity 13 gradually increases. When the body pressure reaches a certain level, the gas will be discharged outward through the exhaust channel 18. The discharged gas acts directly on the side of the linkage belt 5, and the discharged gas will completely blow away the dust, debris and other objects attached to the linkage belt 5, restoring the surface of the linkage belt 5 to cleanliness. This ensures good contact and efficient transmission between the linkage belt 5 and the driven wheel body 4. At the same time, when the discharged gas blows across the surface of the linkage belt 5, it will carry away some heat, playing a role in cooling down the belt and effectively maintaining the stable performance of the linkage belt 5. This provides a strong guarantee for the long-term reliable operation of the entire transmission system.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
