Description
Technical Field
[0001] The present application relates to the technical field of chain conveying equipment, and in particular to a chain conveyor. Background Art
[0002] Chain conveyors use chains as traction and carriers to transport materials. The chains can be ordinary sleeve roller conveyor chains or various other special chains (such as accumulation chains, double-speed chains). Chain conveyors have large conveying capacity and are mainly used to convey pallets, large turnover boxes, etc. The conveyor chain has various structural forms and a variety of accessories, which makes it easy to achieve accumulation and conveying. It can be used as an assembly production line or for material storage and transportation.
[0003] In the process of goods transmission, the chain-driven conveyor mainly transmits through the chain device, and the chain is engaged on the sprocket. Because the chain is long and heavy, the chain needs to be tensioned when installed. During the use of the chain, normal wear and tear will cause the chain to gradually lengthen, resulting in the gradual increase of chain sag, violent chain jumping, increased chain wear, and even tooth jumping and tooth stripping, which reduces the reliability of the work.
[0004] 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
[0005] In order to reduce the maintenance cost of the chain conveyor during use and improve production efficiency, the present application provides a chain conveyor.

[0015] Preferably, a support plate is further provided on the conveying frame, and the support plate is located between the first sprocket and the second sprocket, and the support plate is used to support an external chain.
[0016] By adopting the above technical solution, due to the large length between the first sprocket and the second sprocket, the chain will sag to a certain extent under the action of its own gravity. The support plate can support the chain and reduce the sagging of the chain, so as to better transport the objects.
[0017] Preferably, it further comprises a fixed block and a connecting piece, wherein the fixed block is connected to the conveying frame, the support plate is connected to the fixed block via the connecting piece, and the connecting piece is lifted and lowered on the fixed block.

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.
[0035] The present application embodiment discloses a chain conveyor. Figure 1 and Figure 2The chain conveyor includes a conveying frame 1, a first sprocket 2, a second sprocket 3 and an adjusting assembly 4. The conveying frame 1 serves as a supporting carrier and is fixedly mounted on the ground. The first sprocket 2 is rotatably connected to the conveying frame 1. Specifically, a driving shaft 5 and a driving gear 6 are respectively mounted on the conveying frame 1. The driving shaft 5 is rotatably connected to the conveying frame 1 and is fixedly connected to the axial position of the first sprocket 2, that is, the driving shaft 5 is perpendicular to the plane where the first sprocket 2 is located. The driving gear 6 is fixedly connected to one end of the driving shaft 5 away from the first sprocket 2. The driving gear 6 is connected to an external driving source, and the external driving source is used to control the rotation of the driving gear 6.
[0036] The adjustment assembly 4 is mounted on the conveyor frame 1, and the second sprocket 3 is rotatably connected to the adjustment assembly 4. The rotation axes of the first sprocket 2 and the second sprocket 3 are parallel to each other, and the external chain is simultaneously engaged with the first sprocket 2 and the second sprocket 3. During use, the external driving source controls the driving gear 6 to rotate, and the driving gear 6 then drives the driving shaft 5 and the first sprocket 2 on the driving shaft 5 to rotate. Under the connection of the chain, the first sprocket 2 and the second sprocket 3 are synchronously rotated.
[0037] The linear distance between the axis of the first sprocket 2 and the second sprocket 3 is adjustable, and the adjustment component 4 is used to control the second sprocket 3 to move in a direction close to or away from the second sprocket 3. When the chain is extended, the adjustment component 4 can be used to control the second sprocket 3 to move in a direction away from the first sprocket 2, thereby changing the axis distance between the first sprocket 2 and the second sprocket 3, so as to better adapt to the chain with changed length. In this way, there is no need to replace the chain, thereby reducing the maintenance cost of the chain conveyor during use and improving production efficiency.
[0038] Reference Figure 2 Specifically, the adjustment assembly 4 includes a guide rail 41, a sliding seat 42, a screw rod 43 and a driving member 44. The guide rail 41 is fixedly mounted on the conveying frame 1, and two guide rails 41 are arranged in parallel; the sliding seat 42 is slidingly connected to the two guide rails 41, and the second sprocket 3 is rotationally connected to the sliding seat 42. The screw rod 43 is rotationally connected to the conveying frame 1 and connected to the sliding seat 42, and the rotation axis of the screw rod 43 is parallel to the moving direction of the sliding seat 42. The driving member 44 is connected to one end of the screw rod 43 and is used to control the rotation of the screw rod 43. The driving member 44 can be a driving motor, and the conveying shaft of the driving motor is fixedly connected to the screw rod 43 to realize automatic control of the rotation of the screw rod 43; it can also be a rotating handle, which is fixed to the end of the screw rod 43, and the personnel drives the screw rod 43 to rotate by controlling the rotation of the rotating handle.
[0039] When the position of the second sprocket 3 needs to be adjusted, the driving member 44 can be operated to control the rotation of the screw rod 43. The rotation of the screw rod 43 is converted into a linear motion of the sliding seat 42, so that the sliding seat 42 moves on the guide rail 41, thereby changing the distance between the first sprocket 2 and the second sprocket 3.
[0040] According to some embodiments of the present application, optionally, please refer to Figure 2 The conveying frame 1 is also respectively installed with a fixed block 7, a connecting piece 8 and a support plate 9. The fixed block 7 is fixedly connected to the conveying frame 1 and is located between the first sprocket 2 and the second sprocket 3. The support plate 9 is installed on the fixed block 7 through the connecting piece 8. The support plate 9 is used to support the external conveying chain to reduce the sagging of the chain so as to better convey the objects. Among them, inclined guide surfaces 10 are provided at both ends of the support plate 9. When the chain rotates, the inclined guide surfaces 10 can guide and transition the rotation of the chain.
[0041] In some embodiments, the connecting member 8 is set on the fixed block 7 for lifting, and the connecting member 8 can move up and down along the vertical direction, so that the vertical distance between the support plate 9 and the ground changes, and the lifting movement of the connecting member 8 can be achieved by linear cylinder drive. The staff can control the lifting of the connecting member 8 according to actual needs, adjust the position of the support plate 9, and change the distance between the support plate 9 and the ground, so that the support plate 9 supports the chain at a suitable height position, thereby improving practicality.
[0042] In addition, a collecting tray 11 is installed at the bottom of the conveying frame 1. The collecting tray 11 is located directly below the first sprocket 2 and the second sprocket 3. The collecting tray 11 is used to collect waste materials dropped during the production process. In actual use, some material slag or debris will fall on the conveying chain inside the chain conveyor, and fall to the ground from the gap of the conveying chain, so that the ground at the bottom of the chain conveyor needs to be cleaned frequently. At the same time, after these material slag and debris fall to the ground, they will be contaminated by the dust on the ground and cannot be recycled, resulting in a certain waste of resources. The collecting tray 11 can collect these waste materials and the lubricating oil dripping from the chain, reduce the pollution to the ground, and reduce the difficulty of cleaning.
[0043] The implementation principle of a chain conveyor in an embodiment of the present application is as follows: during use, an external driving source controls the rotation of the driving gear 6, and the driving gear 6 then drives the driving shaft 5 and the first sprocket 2 on the driving shaft 5 to rotate. Under the connection of the chain, the first sprocket 2 and the second sprocket 3 are synchronously rotated to achieve transportation. After the chain is extended, the driving member 44 can be operated to control the screw rod 43 to rotate, so that the sliding seat 42 moves on the guide rail 41 to change the distance between the first sprocket 2 and the second sprocket 3. In this way, there is no need to replace the chain, thereby reducing the maintenance cost of the chain conveyor during use.
[0044] 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.
