Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to an eccentric wheel type lifting and transfer device. Background Technology

[0002] In modern industrial automated production, material lifting and transfer are indispensable key links in assembly line operations, and are widely used in many scenarios such as electronic manufacturing, automobile assembly, and logistics warehousing. Lifting and transfer devices are divided into: cylinder lifting, hydraulic drive, and eccentric wheel lifting, etc.

[0003] Cylinder lifting is significantly affected by air pressure fluctuations, and vibration is prone to occur during the lifting process. For the transfer of precision parts, this may cause the parts to shift position, affecting the subsequent processing accuracy. On the other hand, the transfer accuracy is difficult to guarantee. Although hydraulic drive has a large driving force, the hydraulic system has a slow response speed and potential failure risks such as oil leakage. Eccentric wheel mechanism has the characteristics of simple structure, smooth transmission and easy control, and is widely used.

[0004] Chinese Utility Model Patent Publication No. CN221274206U discloses an eccentric wheel type lifting and transfer device. In this device, four cams abut against the bottom of the inner cover. As the cams move, the inner cover drives two belt conveyors and conveyor motors to rise and fall synchronously. The overall structure is reasonably designed and low in cost, and the lifting process is stable. However, this eccentric wheel type lifting and transfer device only uses cams to lift the upper components, which makes it inconvenient to select whether the transfer device should move laterally or longitudinally according to different situations. This results in the overall device being unsuitable for different working conditions, making it less versatile and difficult to promote its use. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an eccentric wheel type lifting and transfer device, which can effectively solve the problem in the prior art that it is not convenient to select whether the transfer device should move laterally or longitudinally according to different situations, resulting in the overall device being unsuitable for different working conditions, making the overall device less versatile and inconvenient to promote and use.

[0006] The technical solution adopted by this utility model is: an eccentric wheel type lifting and transfer device, including a frame and a transverse moving frame. A base and a mounting frame are fixedly installed on the frame. An eccentric wheel transmission assembly is provided on the frame. A transmission motor is fixedly installed at the end of the base away from the frame. A conveying roller is rotatably installed along the inner edge of the mounting frame.

[0007] The eccentric wheel transmission assembly includes a mounting base and a transmission rod. A transmission motor is fixedly mounted on the mounting base. A gear is fixedly mounted on the output end of the transmission motor. A gear is fixedly mounted on the outer edge of the transmission rod. A chain for transmission is meshed between the gear and the gear. An eccentric wheel body is fixedly mounted on both ends of the transmission rod away from the gear. A mounting rod is fixedly mounted on the end of the eccentric wheel body away from the transmission rod. A base plate is fixedly mounted on the end of the mounting rod away from the transmission rod.

[0008] Preferably, a mounting base two is fixedly installed at the outer edge of the transmission rod, and a fixing rod is fixedly installed at the end of the frame away from the base, wherein the fixing rod and the mounting base two are fixedly installed.

[0009] The above technical solution provides support for the transmission rod by fixing the rod to the mounting base, thus preventing the transmission rod from shaking when the eccentric wheel rotates, which would affect normal use.

[0010] Preferably, a connecting bolt is provided at the end of the mounting rod away from the eccentric wheel body, and the mounting rod is fixedly installed to the base plate through the connecting bolt.

[0011] Through the above technical solution, the design of the connecting bolt allows the connecting bolt to pass through the through hole in the base plate and be threaded to the mounting rod, thus achieving a detachable connection between the mounting rod and the base plate. It also facilitates the movement of parts on the base plate via the eccentric wheel transmission assembly.

[0012] Preferably, a mounting bracket is fixedly installed at the end of the base plate away from the frame, and a drive shaft is rotatably installed at the end of the mounting bracket away from the base plate. Multiple drive wheels are fixedly installed at the outer edge of the drive shaft. A second drive motor is fixedly installed on the base plate, and a second drive wheel is fixedly installed on the output end of the second drive motor. A second drive belt is provided between the drive wheels and the second drive wheel.

[0013] Through the above technical solution, the second drive motor drives the second drive wheel to rotate, and the second drive belt drives the drive wheel on the drive shaft to rotate synchronously. The second drive wheel and the drive wheel form a belt drive structure through the second drive belt, which can transmit the second drive motor to the first chain, thereby driving the items above the transverse moving frame to move laterally. The design of multiple drive wheels can enhance the transmission stability and is suitable for multi-station synchronous transfer scenarios.

[0014] Preferably, a gear is rotatably mounted on the outer edge of the transverse moving frame, and a chain is meshed with the outer edge of the gear, the chain being in contact with the transmission wheel.

[0015] With the above technical solution, when the transmission wheel rotates, it drives the chain to move. The chain drives the transverse moving frame to move laterally through the meshing gear, thus avoiding the use of multiple motors, which would otherwise result in higher costs.

[0016] Preferably, the transverse moving frame, gear one, chain one, and drive wheel are in one-to-one correspondence, the transverse moving frame is fixedly installed with the base plate, and the transverse moving frame, gear one, chain one, and drive wheel are respectively located between the two conveying rollers.

[0017] Through the above technical solution, by cooperating with the transverse moving frame, gear one, chain one and drive wheel, a set of transverse moving frame, gear one, chain one and drive wheel can be set between every two conveying rollers. When transverse movement is performed, the gap between the two sets of transverse moving frames, gear one, chain one and drive wheel can be avoided, so as not to affect normal conveying.

[0018] Preferably, a drive wheel is fixedly installed on the output end of the drive motor, and a transmission belt for transmission is provided between the conveying roller and the drive wheel.

[0019] Through the above technical solution, the drive motor drives the conveyor roller to rotate through the drive wheel and the drive belt. The drive wheel and the conveyor roller form a belt drive structure through the drive belt, realizing the longitudinal conveying of materials on the conveyor roller.

[0020] Compared with the prior art, this utility model provides an eccentric wheel type lifting and transfer device, which has the following beneficial effects:

[0021] This eccentric wheel lifting and transferring device uses eccentric wheels at both ends of a transmission rod to rotate with the transmission rod. Due to the geometric characteristics of the eccentric wheels, their rotation causes the base plate to reciprocate up and down via the mounting rod. When the long shaft end of the eccentric wheel body faces upward, the base plate is lifted to its highest position. At this time, the lateral moving frame is inserted under the material, lifting the material from the conveyor roller. When the short shaft end of the eccentric wheel body rotates to face upward, the base plate descends, and the material falls back onto the conveyor roller. The device can be selected to move laterally or longitudinally depending on the actual situation, making the whole device adaptable to different working conditions, thereby improving the versatility of the whole device and facilitating its widespread use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figures 1-6 As shown, the present invention provides an eccentric wheel type lifting and transfer device, including a frame 1 and a transverse moving frame 11. A base 2 and a mounting frame 7 are fixedly installed on the frame 1. An eccentric wheel transmission assembly 19 is provided on the frame 1. A transmission motor 3 is fixedly installed at the end of the base 2 away from the frame 1. A conveying roller 6 is rotatably installed at the inner edge of the mounting frame 7.

[0031] The eccentric wheel transmission assembly 19 includes a mounting base 1901 and a transmission rod 1906. A transmission motor 1902 is fixedly mounted on the mounting base 1901. A gear 1903 is fixedly mounted on the output end of the transmission motor 1902. A gear 1905 is fixedly mounted on the outer edge of the transmission rod 1906. A chain 1904 for transmission is meshed between the gear 1903 and the gear 1905. An eccentric wheel body 1908 is fixedly mounted on both ends of the transmission rod 1906 away from the gear 1905. A mounting rod 1909 is fixedly mounted on one end of the eccentric wheel body 1908 away from the transmission rod 1906. A base plate 8 is fixedly mounted on one end of the mounting rod 1909 away from the transmission rod 1906.

[0032] Specifically, a mounting base 1907 is fixedly installed on the outer edge of the transmission rod 1906, and a fixing rod 18 is fixedly installed on the end of the frame 1 away from the base 2. The fixing rod 18 and the mounting base 1907 are fixedly installed. The advantage is that the fixed connection between the fixing rod 18 and the mounting base 1907 can support the transmission rod 1906, which can prevent the transmission rod 1906 from shaking when the eccentric wheel body 1908 rotates, thus affecting normal use.

[0033] Specifically, a connecting bolt 1910 is provided at the end of the mounting rod 1909 away from the eccentric wheel body 1908. The mounting rod 1909 is fixedly installed to the base plate 8 through the connecting bolt 1910. The advantage is that, through the design of the connecting bolt 1910, the connecting bolt 1910 can be threaded through the through hole of the base plate 8 and fixed to the mounting rod 1909, realizing the detachable connection between the mounting rod 1909 and the base plate 8, and also facilitating the movement of parts on the base plate 8 through the eccentric wheel transmission assembly 19.

[0034] Specifically, a mounting bracket 9 is fixedly installed at the end of the base plate 8 away from the frame 1. A drive shaft 10 is rotatably installed at the end of the mounting bracket 9 away from the base plate 8. Multiple drive wheels 14 are fixedly installed at the outer edge of the drive shaft 10. A second drive motor 15 is fixedly installed on the base plate 8. A second drive wheel 16 is fixedly installed on the output end of the second drive motor 15. A second drive belt 17 is provided between the drive wheel 14 and the second drive wheel 16. The advantage is that the second drive motor 15 drives the second drive wheel 16 to rotate, and drives the drive wheel 14 on the drive shaft 10 to rotate synchronously through the second drive belt 17. The second drive wheel 16 and the drive wheel 14 form a belt drive structure through the second drive belt 17, which can transmit the second drive motor 15 to the chain 13, thereby driving the items above the transverse moving frame 11 to move laterally. The design of multiple drive wheels 14 can enhance the transmission stability and is suitable for multi-station synchronous transfer scenarios.

[0035] Example 2: Figures 2-6 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, a gear 12 is rotatably mounted on the outer edge of the transverse moving frame 11, and a chain 13 is meshed with the outer edge of the gear 12. The chain 13 is in contact with the transmission wheel 14. The advantage is that when the transmission wheel 14 rotates, it drives the chain 13 to move. The chain 13 drives the transverse moving frame 11 to move laterally through the meshing gear 12, avoiding the use of multiple motors, which would otherwise result in higher costs.

[0037] Specifically, the transverse moving frame 11, gear 12, chain 13, and drive wheel 14 are in one-to-one correspondence. The transverse moving frame 11 is fixedly installed on the base plate 8. The transverse moving frame 11, gear 12, chain 13, and drive wheel 14 are located between the two conveying rollers 6. The advantage is that, through the cooperation of the transverse moving frame 11, gear 12, chain 13, and drive wheel 14, a set of transverse moving frames 11, gear 12, chain 13, and drive wheel 14 can be set between every two conveying rollers 6. When transverse movement is performed, the gap between the two sets of transverse moving frames 11, gear 12, chain 13, and drive wheel 14 can be avoided to prevent large gaps that would affect normal conveying.

[0038] Specifically, a drive wheel 4 is fixedly installed on the output end of the drive motor 3, and a transmission belt 5 for transmission is provided between the conveying roller 6 and the drive wheel 4. The advantage is that the drive motor 3 drives the conveying roller 6 to rotate through the drive wheel 4 and the transmission belt 5. The drive wheel 4 and the conveying roller 6 form a belt drive structure through the transmission belt 5, realizing the longitudinal conveying of materials on the conveying roller 6.

[0039] Working principle: During use, the eccentric wheel bodies 1908 at both ends of the transmission rod 1906 rotate with the transmission rod 1906. Due to the geometric characteristics of the eccentric wheels, their rotation will drive the base plate 8 to reciprocate up and down through the mounting rod 1909. When the long shaft end of the eccentric wheel body 1908 is facing upward, the base plate 8 is lifted to its highest position. At this time, the transverse moving frame 11 is inserted under the material, lifting the material from the conveying roller 6. When the eccentric wheel body 1908 rotates to the point where the short shaft end is facing upward, the base plate 8 descends, and the material falls back onto the conveying roller 6. The transmission rod 1906 passes through the mounting base 1. 907 is fixed to the frame 1 with the fixed rod 18 to prevent the transmission rod 1906 from shaking when the eccentric wheel rotates. When the transmission wheel 14 rotates, it drives the chain 13 to move. The chain 13 meshes with the gear 12, driving the transverse moving frame 11 fixed on the base plate 8 to make transverse linear motion. The transmission motor 3 drives the conveying roller 6 to rotate through the drive wheel 4 and the transmission belt 5 to realize the longitudinal conveying of materials on the conveying roller 6. When the base plate 8 is lifted, the material is separated from the conveying roller 6 and is carried by the transverse moving frame 11. When the base plate 8 is lowered, the material falls back to the conveying roller 6 to continue longitudinal conveying.

[0040] 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.
