Description

Technical Field

[0001] The present application relates to the technical field of transmission conveying devices, and in particular to a cross chain corner conveying device. Background Art

[0002] There are many forms of transmission devices used for power output. Among them, the transmission device suitable for power output over longer distances uses a flexible transmission body as the medium for power transmission. Among the flexible transmission bodies, belts and chains are the most common. Belts and pulleys are used to transmit power, and then used with pulley groups of different specifications to achieve the purpose of speed change. Chains and sprocket groups are used together. Similarly, in addition to transmitting power, they can also achieve the purpose of speed change.

[0003] In actual use, these two types of transmission devices have their own characteristics. The design of the belt and pulley assembly is simpler, but because it can only rely on the friction generated by the belt to achieve the purpose of friction transmission, it is easier to slip during the power transmission process, resulting in the inability to achieve the best efficiency in power transmission. The chain and sprocket assembly are transmitted in the form of chain teeth meshing, so they can maintain a very certain meshing state, making the power transmission efficiency extremely good.

[0004] Chain conveyors use chains as traction and carriers to transport materials. Chain conveyors have large conveying capacity and are mainly used to transport pallets, large turnover boxes, etc. They are easy to realize accumulation and delivery, and can be used as assembly production lines or as material storage and delivery. The chain can be an ordinary sleeve roller conveyor chain or other special chains (such as accumulation and delivery chains, double-speed chains).

[0005] like Figure 1 The cross chain shown in the figure, in the process of conveying goods, the chain conveyor needs to be tensioned during installation because the chain is long and heavy. During long-term use, the normal wear of the chain will gradually lengthen the chain, causing the chain sag to gradually increase, the chain to jump violently, the chain to wear more, and even the phenomenon of tooth jumping and tooth stripping, which reduces the reliability of the work.

[0006] Regarding the above-mentioned related technologies, when the chain is stretched, the traditional method is mostly to directly replace the entire chain. This method has high maintenance costs and low production efficiency, so it needs to be improved. Utility Model Content

[0007] In order to reduce the maintenance cost of the chain conveyor during use, the present application provides a cross chain corner conveyor.

[0008] The cross chain corner conveying device provided in the present application adopts the following technical solution:

[0014] By adopting the above technical solution, when the distance between the first straight rail and the curved rail needs to be adjusted, the operating drive controls the screw to rotate, and the rotation of the screw is converted into linear motion of the moving frame, so that the moving frame moves with the first straight rail and the second straight rail in a direction away from the curved rail, thereby completing the adjustment of the circumference of the entire conveying track.

[0018] By adopting the above technical solution, when the moving frame moves, the guide rod can limit and guide the moving frame, thereby improving the stability of the moving frame during the movement.

[0019] Preferably, the frame is also rotatably connected to a plurality of pulleys, and the movable frame is provided with a slide groove along its own moving direction, and the pulleys roll in the slide groove.

[0020] By adopting the above technical solution, when the movable frame moves linearly, the movable frame and the frame will move relative to each other, and the pulley will rotate in the slide groove at this time, and the pulley can guide the movement of the movable frame.

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples shown in the present application.

[0038] The present application embodiment discloses a cross chain corner conveying device. Figure 2 and Figure 3 The corner conveying device includes a frame 1, a conveying track 2, a connecting component 3 and an adjusting component 4. The frame 1 serves as a carrier, and the conveying track 2 is installed on the frame 1. The conveying track 2 is provided with a cross groove along its circumference, and the cross chain is installed in the cross groove. In this embodiment, the outer surface of the conveying track 2 is coated with a paint layer. The paint layer can form a protective film on the outer surface of the conveying track 2, reduce physical damage, chemical corrosion, etc. on the surface of the conveying track 2, and thus extend the service life. At the same time, the paint layer can also provide color and gloss to improve the aesthetics.

[0039] The conveying track 2 includes a first straight rail 21, a curved rail 22 and a second straight rail 23. The curved rail 22 is arranged in an arc shape. The first straight rail 21 and the second straight rail 23 are parallel to each other and are respectively located at the two ends of the arc of the curved rail 22; the first straight rail 21 and the second straight rail 23 can both be movably arranged, and the first straight rail 21 and the second straight rail 23 are connected by a connecting component 3 and an adjusting component 4. The adjusting component 4 is used to control the first straight rail 21 and the second straight rail 23 to move synchronously.

[0040] Specifically, the connecting assembly 3 includes a fixed block 31 and a connecting block 32. The connecting block 32 is fixedly connected to the first straight rail 21. Two fixed blocks 31 are arranged at intervals. The two fixed blocks 31 are respectively connected to the two ends of the connecting block 32. At the same time, the two fixed blocks 31 are connected to the adjusting assembly 4.

[0041] The adjustment assembly 4 includes a screw rod 41, a movable frame 42 and a driving member 43. The screw rod 41 is rotatably connected to the frame 1, and the movable frame 42 is slidably connected to the screw rod 41. The movable frame 42 moves linearly along the length direction of the screw rod 41. The fixed block 31 is fixedly connected to the movable frame 42 to realize the indirect connection between the first straight rail 21 and the movable frame 42. The driving member 43 is connected to one end of the screw rod 41 to control the rotation of the screw rod 41. The driving member 43 can be a rotary motor, and the output shaft of the rotary motor is connected to the screw rod 41; of course, it can also be a rotating handle, and the rotating handle is directly fixedly connected to the screw rod 41.

[0042] When the driving member 43 is operated, the screw rod 41 starts to rotate, and the rotation of the screw rod 41 can be transformed into the linear motion of the moving frame 42, so that the moving frame 42 moves with the first straight rail 21 and the second straight rail 23 in the direction away from the curved rail 22, thereby completing the adjustment of the circumference of the entire conveying track 2. In this way, the circumference of the conveying track 2 can adapt to the cross chain with a changed length, so that there is no need to replace the entire chain, thereby reducing the maintenance cost of the chain conveying device.

[0043] In addition, the frame 1 is also provided with a guide rod 5 and a pulley 6, respectively. The guide rod 5 and the screw rod 41 are parallel to each other, and the moving direction of the guide rod 5 is the same as the moving direction of the mobile frame 42. The guide rod 5 is connected to the mobile frame 42, and is used to guide and limit the movement of the mobile frame 42, so as to improve the stability of the mobile frame 42 during the movement. Among them, a plurality of pulleys 6 are provided, and each pulley 6 can be rotatably connected to the frame 1; a slide groove 7 is provided on the mobile frame 42 along its own moving direction, and the pulley 6 can roll in the slide groove 7. When the mobile frame 42 moves in a straight line, the mobile frame 42 and the frame 1 will move relative to each other, and at this time, the pulley 6 will rotate in the slide groove 7, and the pulley 6 plays a guiding role for the movement of the mobile frame 42.

[0044] According to some embodiments of the present application, optionally, please refer to Figure 3 . A guide bar 8 is also fixedly connected to the end of the curved rail 22, and the guide bar 8 is arranged along the moving direction of the first straight rail 21; a guide groove 9 is provided at one end of the first straight rail 21 close to the curved rail 22, and the guide bar 8 is clamped in the guide groove 9. The connection method between the second straight rail 23 and the curved rail 22 is the same as that of the first straight rail 21, and is not elaborated here. When the first straight rail 21 gradually moves away from the curved rail 22, the guide bar 8 can move in the guide groove 9, and the connection between the first straight rail 21 and the curved rail 22 is realized without interfering with the relative movement of the first straight rail 21 and the curved rail 22, thereby increasing the stability of the entire conveying track 2.

[0045] The implementation principle of a cross chain corner conveying device in the embodiment of the present application is as follows: the cross chain is arranged along the circumference direction of the conveying track 2. When the cross chain is extended during long-term use, the adjustment component 4 can be used to control the synchronous movement of the first straight rail 21 and the second straight rail 23. The distance between the first straight rail 21 and the curved rail 22 increases, and the distance between the second straight rail 23 and the curved rail 22 also increases accordingly, that is, the circumference of the entire conveying track 2 changes, thereby adapting to the cross chain with a changed length. In this way, there is no need to replace the entire chain, thereby reducing the maintenance cost of the chain conveying device.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
