A folding roller conveyor and its usage method

Abstract

This invention discloses a folding roller conveyor and its usage method, including a frame, rollers, roller motor, support frame, and folding frame. The rollers are located inside the frame, the roller motor is located on the outside of the frame, the support frame is located at the bottom of the frame, and the folding frame is located between two frames. The folding roller conveyor and its usage method involve rotating an inner shaft driven by the roller motor. The inner shaft drives a chain via sprockets, and the chain's movement drives all sprockets to rotate, thus transporting objects. After transport, rotating the outer plate causes the rack to return to the interior frame, releasing the locking mechanism. One of the frame bodies is then flipped, folding onto the other frame body, and the interior frame is locked again. Finally, the support column is stored in the storage slot, reducing the space occupied by the roller conveyor during transport.

Description

Technical Field

[0001] This invention relates to the field of roller conveyor technology, and in particular to a folding roller conveyor and its usage method. Background Technology

[0002] Roller conveyors are suitable for conveying various bags and other items with flat bottoms. They have a large conveying capacity and are lightweight, making them widely used in various industries and enabling them to provide uniform conveying of items.

[0003] However, the following problems often occur during the use of roller conveyors:

[0004] (1) During the conveying process of the roller conveyor, there will be a problem that the conveying distance of a single roller conveyor is too short. Therefore, during use, it is necessary to provide another roller conveyor to connect with it to extend the conveying distance. However, during the connection process between the first roller conveyor and the second roller conveyor, there will not only be a problem with the transportation of the second roller conveyor, but also a deviation will occur during use after the connection with the first roller conveyor, which may cause other problems such as jamming after the connection, affecting normal conveying.

[0005] (2) During the use of the roller conveyor, it may be necessary to transfer the roller conveyor to the destination. During the overall transportation of the roller conveyor, because of its large size and the fact that most of its additional components also occupy a lot of space, only a single roller conveyor can be transported at a time, and its transportation efficiency is poor. Summary of the Invention

[0006] The purpose of this invention is to provide a foldable roller conveyor and its usage method, which solves the problems of displacement after docking of existing roller conveyors and the inconvenience of transporting the entire roller conveyor, thereby addressing the issues raised in the background art.

[0007] To achieve the above objectives, the present invention proposes the following solution:

[0008] A folding roller conveyor and its method of use include a frame, rollers, roller motor, support frame and folding frame. The rollers are provided inside the frame, the roller motor is provided on the outside of the frame, the support frame is provided at the bottom of the frame, and the folding frame is provided between the two frames.

[0009] The folding frame includes an external end, a connecting shaft, an internal end, a connecting rod, a nested frame, and a mating end. The connecting shaft is fixedly connected to the inner side of the external end. The internal end is fixedly connected to the end of the connecting shaft away from the external end. The connecting rod is fixedly connected to one side of the external end. The nested frame is fixedly connected to the end of the connecting rod away from the external end. The mating end is provided inside the nested frame.

[0010] Furthermore, the external end includes an external frame, an internal rod, an external plate, a limiting groove, and a limiting plate. The internal rod is provided inside the external frame, and one end of the internal rod is inserted into the external plate. A limiting groove is provided on the side of the external frame near the external plate. A limiting plate is provided inside the external plate, and the limiting plate is fixedly connected to the internal rod.

[0011] Furthermore, the built-in end includes a built-in frame, a sliding frame, a rack, and a built-in gear. The built-in frame has a sliding frame inside, and a sliding groove is opened inside the sliding frame. At the same time, a rack is provided inside the sliding groove. The rack is slidably connected to the sliding frame. The built-in gear is provided on the side of the rack away from the sliding frame, and the external teeth on the built-in gear mesh with the tooth groove on the rack.

[0012] Furthermore, the frame includes a body frame, side slots, a bottom frame, a storage slot, and a limiting protrusion. Side slots are provided on both sides of the body frame, and a bottom frame is fixedly connected to the bottom end of the body frame. Storage slots are provided on both sides of the bottom frame, and a limiting protrusion is provided inside the storage slot. The limiting protrusion is fixedly installed on the bottom frame.

[0013] Furthermore, the roller includes an inner shaft, a sprocket, and a chain. The sprocket is provided on the outer side of the inner shaft, and the sprocket is fixedly connected to the inner shaft after being penetrated by the inner shaft. The chain is provided on the outer side of the sprocket, and the chain is nested on the sprocket. The tooth grooves inside the chain mesh with the chain teeth on the sprocket.

[0014] Furthermore, the support frame includes a support column body, a grounding end, a telescopic column, and a return spring. The support column body is movably connected to the frame. The bottom end of the support column body is fixedly connected to the grounding end. The grounding end has a telescopic column inside, and the inner column of the telescopic column is fixedly installed on the grounding end. The outer column of the telescopic column passes through the grounding end. A return spring is wound on the inner column of the telescopic column. One end of the return spring is fixedly installed on the grounding end, and the other end of the return spring is fixedly connected to the outer column of the telescopic column.

[0015] The present invention provides a technical solution, a method of using a folding roller conveyor, comprising the following steps:

[0016] Step 1: By rotating the outer plate clockwise, the outer plate drives the inner rod to rotate clockwise, and the inner gear rotates accordingly. Through the meshing between the inner gear and the rack, the rack slides down in the sliding frame, so that the sliding frame is completely inside the inner frame, so that the limiting end of the rack can no longer limit the sliding of the inner frame in the side groove. At this time, the two body frames are connected to each other.

[0017] Step 2: After aligning the two fuselage frames, rotate the outer plate counterclockwise again. The outer plate drives the inner rod to rotate counterclockwise, and the inner gear follows the rotation. The inner gear drives the rack to slide upward in the sliding frame, so that the limiting end of the rack moves out of the inner frame and connects with the fuselage frame. The limiting end of the rack restricts the movement of the inner frame in the side slot. At the same time, insert the outer plate into the limiting slot to restrict the rotation of the inner rod and the movement of the rack.

[0018] Step 3: After the two machine frames are connected, start the roller motor. The rotating shaft at the front end of the roller motor drives an inner shaft inside the machine frame to rotate. At the same time, the sprocket on the inner shaft rotates. Through the meshing between the sprocket and the chain, the sprocket drives the chain to move during rotation. The movement of the chain drives the other sprockets to rotate, and their corresponding inner shafts rotate synchronously, which can transport the objects on the roller.

[0019] Step 4: After the conveying is completed, rotate the outer plate clockwise again to put the rack into the inner frame. The inner frame moves freely in the side slot, separating the two body frames to the farthest distance. Flip one of the body frames so that it folds together with the other body frame. Then rotate the outer plate counterclockwise to limit the inner frame and also limit the two folded body frames.

[0020] Step 5: Rotate the support body inward, and the support body enters the storage slot. At the same time, the outer column of the telescopic column is squeezed by the inclined surface of the limiting convex plate and first retracts into the inner column, compressing the return spring. After passing the protrusion of the limiting convex plate, the outer column of the telescopic column is on the inclined surface on the other side. The rebound force of the return spring helps the outer column of the telescopic column extend outward, so that the limiting convex plate limits the outer column of the telescopic column, thereby limiting the support body.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The present invention discloses a folding roller conveyor and its usage method. By using a nested frame to connect the body frames of two roller conveyors to the docking end, the straight connection of the two roller conveyors is maintained. Furthermore, the sliding of the inner frame in the side groove is used to adjust the distance between the two roller conveyors, so that no positional offset is found after the two roller conveyors are docked. At the same time, gaps caused by offset are avoided, allowing objects to be smoothly transported from the first roller conveyor to the second roller conveyor during the conveying process.

[0023] The present invention discloses a folding roller conveyor and its usage method. After two roller conveyors are docked, the frame of one of the roller conveyors is flipped. After the flipping is completed, the frame is locked by a rack and pinion, thereby folding the roller conveyor and storing the support bodies of both roller conveyors in the storage slot. This effectively reduces the space occupied by the two roller conveyors and facilitates the transportation of the roller conveyors. Attached Figure Description

The limiting plate 515 can move back and forth in the inner cavity of the external plate 513. When the external plate 513 rotates, the limiting plate 515 and the internal rod 512 rotate together.

[0036] The built-in end 53 includes a built-in frame 531, a sliding frame 532, a rack 533, and a built-in gear 534. The built-in frame 531 has a sliding frame 532 inside, and a sliding groove is opened inside the sliding frame 532. The rack 533 is also provided inside the sliding groove. The rack 533 is slidably connected to the sliding frame 532. The built-in gear 534 is provided on the side of the rack 533 away from the sliding frame 532.

The limiting protrusion 15 is fixedly installed on the bottom frame 13.

[0038] The roller 2 includes an inner shaft 21, a sprocket 22, and a chain 23. The sprocket 22 is located on the outer side of the inner shaft 21. The roller body is located on the outer side of the inner shaft 21 between the two sprockets 22. The inner shaft 21 is fixedly connected to the roller body. The sprocket 22 is fixedly connected to the inner shaft 21 after being penetrated by the inner shaft 21. The chain 23 is located on the outer side of the sprocket 22. The chain 23 is nested on the sprocket 22. The tooth groove inside the chain 23 meshes with the chain teeth on the sprocket 22. Both the sprocket 22 and the chain 23 are located inside the machine frame 11.

[0039] The support frame 4 includes a support body 41, a grounding end 42, a telescopic column 43, and a return spring 44. The support body 41 is movably connected to the frame 1 and rotates around the top of the support body 41. The bottom end of the support body 41 is fixedly connected to the grounding end 42. The telescopic column 43 is provided inside the grounding end 42, and the inner column of the telescopic column 43 is fixedly installed on the grounding end 42. The outer column of the telescopic column 43 passes through the grounding end 42. The return spring 44 is wound on the inner column of the telescopic column 43. One end of the return spring 44 is fixedly installed on the grounding end 42, and the other end of the return spring 44 is fixedly connected to the outer column of the telescopic column 43. When the telescopic column 43 is compressed, the outer column enters the grounding end 42, and the inner column enters the outer column. The return spring 44 is compressed, and the rebound force of the compressed return spring 44 helps the outer column of the telescopic column 43 to pop out and return to its original position.

[0040] The specific operation process is as follows: Step 1: By rotating the outer plate 513 clockwise, the outer plate 513 drives the inner rod 512 to rotate clockwise, and the inner gear 534 follows the rotation. Through the meshing between the inner gear 534 and the rack 533, the rack 533 slides downward in the sliding frame 532, so that the sliding frame 532 is completely inserted into the inner frame 531, so that the limiting end of the rack 533 can no longer limit the sliding of the inner frame 531 in the side groove 12. At this time, the two body frames 11 are connected to each other; Step 2: After the two body frames 11 are aligned, rotate the outer plate 513 counterclockwise again. The outer plate 513 drives the inner rod 512 rotates counterclockwise, and the built-in gear 534 rotates accordingly. The built-in gear 534 drives the rack 533 to slide upward in the sliding frame 532, so that the limiting end of the rack 533 moves out of the interior of the built-in frame 531 and connects with the machine frame 11. The limiting end of the rack 533 restricts the movement of the built-in frame 531 in the side groove 12. At the same time, the outer plate 513 is inserted into the limiting groove 514 to restrict the rotation of the built-in rod 512 and the movement of the rack 533. Third step: After the two machine frames 11 are connected, the roller motor 3 is started. The rotating shaft at the front end of the roller motor 3 drives an inner shaft 21 inside the machine frame 11 to rotate. The inner shaft 21 rotates simultaneously with the sprocket 22 on the inner shaft 21. Through the meshing between the sprocket 22 and the chain 23, the sprocket 22 drives the chain 23 to move during rotation. The movement of the chain 23 drives the other sprockets 22 to rotate, and the corresponding inner shaft 21 rotates synchronously, which can transport the objects on the roller 2. Fourth step: After the transport is completed, rotate the outer plate 513 clockwise again to put the rack 533 into the inner frame 531. The inner frame 531 moves freely in the side groove 12, separating the two machine frame 11 to the farthest distance. Flip one of the machine frame 11 so that it folds together with the other machine frame 11, and then reverse the direction. The outer plate 513 is rotated clockwise to limit the inner frame 531 and also to limit the two folded body frames 11. Fifth step: The support body 41 is rotated inward and enters the storage slot 14. At the same time, the outer column of the telescopic column 43 is squeezed into the inner column by the inclined surface of the limiting convex plate 15 and compresses the return spring 44. After passing the convex point of the limiting convex plate 15, the outer column of the telescopic column 43 is on the inclined surface on the other side. The rebound force of the return spring 44 helps the outer column of the telescopic column 43 to extend outward, so that the limiting convex plate 15 limits the outer column of the telescopic column 43, thereby limiting the support body 41.

[0041] In summary, the present invention proposes a folding roller conveyor and its usage method. During use, the outer frames 511 of two roller conveyors are brought close together, and the mating end 56 of one of the outer frames 511 is nested into the nesting frame 55. The inner frame 531 slides in its respective side groove 12, bringing the two machine frame 11 close together and achieving mating. Then, the rack 533 locks the inner frame 531 to the machine frame 11 to prevent displacement. The roller motor 3 drives the inner shaft 21 to rotate. The inner shaft 21 drives the chain 23 through the sprocket 22. The movement of the chain 23 drives all the sprockets 22 to rotate, realizing the transportation of objects. After the transportation is completed, the outer plate 513 is rotated so that the rack 533 returns to the inside of the inner frame 531 and no longer locks the inner frame 531. One of the body frames 11 is flipped so that one body frame 11 is folded onto the other body frame 11. The movement of the inner frame 531 is locked again. Then the support body 41 is stored in the storage slot 14, which can reduce the space occupied by the roller conveyor during transportation.
