Technical Field
[0001] This utility model relates to the technical field of mesh belt conveyor structure, specifically to a conveyor chain anti-jamming structure and its mesh belt conveyor. Background Technology
[0002] Mesh belt conveyors are automated equipment that uses metal mesh belts or chains as the transmission carrier for the continuous transport of materials. They are widely used in food processing, metallurgy, chemical industry, electronic assembly and other industries.
[0003] During operation, the chain in the mesh belt conveyor has a loose end and a tight end. The tight end bears the tension of the drive sprocket and is responsible for transmitting power and load. It must maintain high tension to ensure stable meshing between the chain and the sprocket. The loose end is used to absorb changes in chain length caused by load changes, thermal expansion and contraction, or wear.
[0004] However, because there is a certain gap between the chain and the track end in the mesh belt conveyor, after the loose end of the chain droops, the chain rollers or chain links may get stuck in the gap between the track end and the chain gear, resulting in jamming and collision problems. Utility Model Content

[0007] Furthermore, the anti-jamming support plate is arranged inclined downwards from the end connected to the anti-jamming support plate, and the projection of the sprocket engaged with the loose end of the conveyor chain on the anti-jamming support plate in the vertical direction is located inside the anti-jamming support plate.
[0008] The second aspect of this utility model adopts the following technical solution: a mesh belt conveyor, including the anti-jamming structure of the conveyor chain described in the first aspect of this utility model.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] This conveyor chain anti-jamming structure uses an anti-jamming support plate to ensure that the loose end of the conveyor chain can be fully supported on the anti-jamming support plate, which helps to reduce jamming and collision. Attached Figure Description

Detailed Implementation
[0015] The present invention will be further described in detail below through specific embodiments:
[0016] like Figure 1 and Figure 2 As shown, this utility model embodiment proposes an anti-jamming structure for a conveyor chain, including an anti-jamming support plate 1 disposed below the loose end of the conveyor chain 5 and connected to a track that cooperates with the conveyor chain 5. The anti-jamming support plate 1 is slidably supported below the loose end of the conveyor chain 5. The anti-jamming support plate 1 is arranged inclined downward from the end connected to it, and the projection of the sprocket 6 that cooperates with the loose end of the conveyor chain 5 in the vertical direction on the anti-jamming support plate 1 is located inside the anti-jamming support plate 1.
[0017] The anti-jamming structure of this conveyor chain ensures that the loose end of the conveyor chain 5 can be fully supported on the anti-jamming support plate 1 through the design of the anti-jamming support plate 1, which helps to reduce jamming and collision.
[0018] To further reduce the occurrence of jamming and collisions, such as Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, the anti-jamming structure for the conveyor chain has an angle of 25° between the anti-jamming support plate 1 and the horizontal plane.
[0019] To further reduce the occurrence of jamming and collisions, such as Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, the conveyor chain anti-jamming structure wherein the anti-jamming support plate 1 has an integrally formed mesh belt side wheel guard plate 2 located on the loose end side of the conveyor chain 5 for protection.
[0020] In this embodiment, the mesh belt side wheel guard plate 2 is in the shape of a right triangle.
[0021] To further reduce the occurrence of jamming and collisions, such as Figure 2 As shown, according to another embodiment of the present invention, the conveyor chain anti-jamming structure further includes a tension adjustment component 3 connected to a chain gear 6 that cooperates with the tight end of the conveyor chain 5.
[0022] The tension of the conveyor chain 5 is adjusted by the tension adjustment component 3 according to the requirements, so that the conveyor chain 5 meets the transmission requirements and reduces jamming and collision.
[0023] In this embodiment, the tension adjustment assembly 3 includes a slider bearing 31, a support part, and an adjustment screw 32. The slider bearing 31 is rotatably connected to the corresponding sprocket 6. The support part is fixedly connected to the outer side of the slider bearing 31.
[0024] The adjusting screw 32 is rotatably connected to the slider bearing 31 and is threadedly connected to the support.
[0025] The support unit serves as a support frame in the mesh belt conveyor, providing support for the adjusting screw 32. Rotating the adjusting screw 32 drives the slider bearing 31 to move, thereby moving the corresponding sprocket 6 and adjusting the distance between the two sprockets 6, thus adjusting the tension of the conveyor chain 5. Specifically, after the adjusting screw 32 freely passes through the connecting hole on the slider bearing 31, the limiting head on the adjusting screw 32 ensures that the adjusting screw 32 and the slider bearing 31 are stably connected in a rotating manner. The slider bearing 31 is slidably connected to the support frame to prevent the slider bearing 31 from rotating with the adjusting screw 32.
[0026] To further reduce the occurrence of jamming and collisions, such as Figure 2 and Figure 3 As shown, according to another embodiment of the present invention, the conveyor chain anti-jamming structure wherein the top of the anti-jamming support plate 1 is provided with an oil injection component 4 for lubricating the conveyor chain 5.
[0027] The lubrication component 4 sprays lubricating oil onto the conveyor chain 5 as needed to lubricate the conveyor chain 5 and further reduce the occurrence of jamming and collision.
[0028] Based on the above solution:
[0029] The oil injection assembly 4 includes an oil storage box 41, an oil injection hole 42, and an oil injection structure. The oil storage box 41 is fixedly installed on the top and bottom surfaces of the anti-jamming support plate 1. There are multiple oil injection holes 42, which are arranged at intervals along the width direction of the anti-jamming support plate 1 on the top surface of the anti-jamming support plate 1. All oil injection holes 42 are connected to the inside of the oil storage box 41. The oil injection structure cooperates with the oil storage box 41 and is used to squeeze the lubricating oil in the oil storage box 41 out of the oil injection hole 42.
[0030] During use, the lubricating oil in the oil storage box 41 is squeezed out from the oil injection hole 42 and sprayed onto the loose end of the conveyor chain 5 through the oil injection structure to lubricate the loose end of the conveyor chain 5, so as to further reduce the occurrence of jamming and collision.
[0031] The oil injection structure includes a push block 43 and a driving part. The push block 43 is slidably disposed in the oil storage box 41. The driving part is connected to the push block 43 and is used to drive the push block 43 to slide.
[0032] Here, the driving unit can be a manual push rod 44 or an electric telescopic rod connected to the push block 43. The manual push rod 44 manually drives the push block 43 to move within the oil reservoir 41, squeezing the lubricating oil in the oil reservoir 41 out through the oil injection hole 42 and spraying it onto the slack end of the conveyor chain 5 to lubricate it. The electric telescopic rod electrically drives the push block 43 to move.
[0033] Furthermore, an elastic reset member 45 is provided between the push block 43 and the inner wall of the oil storage box 41 to drive the push block 43 to reset. The elastic reset member 45 can be a spring. In this case, the driving part is a manual push rod 44. When the manual push rod 44 is released, the push block 43 moves in the opposite direction under the action of the spring to reset, so as to prevent lubricating oil from seeping out from the oil injection hole 42.
[0034] In the above, the oil storage box 41 can be a groove structure with one end open. The open end of the groove structure is connected to the top and bottom surface of the anti-jamming support plate 1, so the space inside the groove structure is connected to the oil filling hole 42. A filling port is also provided on the groove structure, through which lubricating oil can be added to the groove structure. The filling port is sealed with a sealing plug when not in use.
[0035] The sealing plug can be locked in place with bolts to improve its assembly stability.
[0036] According to another embodiment of the present invention, the mesh belt conveyor includes a conveyor chain anti-jamming structure as described in any of the above embodiments, so that the mesh belt conveyor has the advantages of the above-mentioned conveyor chain anti-jamming structure.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
