A conveyor slat, a conveyor chain assembly using the slat, and a conveyor

Abstract

The present invention relates to a conveyor slat and a conveyor chain assembly and a conveyor using the slat. The slat includes a supporting base plate. The two sides of the supporting base plate are respectively provided with a first arc-shaped matching portion and a second arc-shaped matching portion. The opening direction of the first arc-shaped matching portion is the same as the opening direction of the second arc-shaped matching portion. The first arc-shaped matching portion and the second arc-shaped matching portion are located on the same side of the supporting base plate. The radius of the first arc-shaped matching portion is larger than the radius of the second arc-shaped matching portion. The first arc-shaped matching portion is used for the second arc-shaped matching portion on the adjacent slat to be matched and inserted so as to be buckled up and down and the two are arranged concentrically. There is a gap between the first arc-shaped matching portion of one of the two adjacent slats and the second arc-shaped matching portion matched therewith. Debris can enter the gap and be temporarily retained. When the slat is rotated to the sprocket, the above gap becomes larger, and the retained powdery debris falls from the gap, thereby avoiding the problem of debris falling from the gap between the slats.

[0027] Embodiment 1 of a conveyor of the present invention, as Figure 1-Figure 6 As shown, it includes a frame, a sprocket and a conveying chain assembly are arranged on the frame, and the conveying chain assembly includes two roller chains 2 arranged in parallel and spaced apart and matched with the sprocket transmission and a plurality of slats 1 arranged between the two roller chains 2. The roller chain 2 includes an inner chain plate 21, an outer chain plate 22 and a pin 23, and a roller 24 is arranged on the pin 23. A first connecting hole 14 is arranged on each slat, and a connecting plate is arranged on the inner chain plate 21, and a second connecting hole 25 is arranged on the connecting plate. The first connecting hole and the second connecting hole are connected by a connecting bolt 31 and a nut 32. The roller chain belongs to the prior art, and its structure is not described in detail in this embodiment.

[0028] The slat 1 includes a supporting substrate 11, and the supporting substrate 11 is respectively provided with a first arc-shaped matching portion 12 and a second arc-shaped matching portion 13 on both sides along the conveying direction. In this embodiment, the slat is formed by bending both sides of a metal plate in one piece. The opening direction of the first arc-shaped matching portion 12 is the same as the opening direction of the second arc-shaped matching portion 13, and the first arc-shaped matching portion and the second arc-shaped matching portion are located on the same side of the supporting substrate 11. The radius of the first arc-shaped matching portion 12 is greater than the radius of the second arc-shaped matching portion 13. The first arc-shaped matching portion is used for the second arc-shaped matching portion on the adjacent slat to fit in and fit together to achieve upper and lower snap-fit, and the two are concentrically arranged with the corresponding pin shaft on the roller chain. There is a gap D between the first arc-shaped matching portion of any slat and the second arc-shaped matching portion of the adjacent slat, and the gap D forms a powder retention groove.

[0029] When in use, there is a gap between the first arc-shaped mating portion of one of the two adjacent slats and the second arc-shaped mating portion that matches it. Large pieces of debris are difficult to enter the gap, but small or powdery debris T can enter the gap and be temporarily retained without falling into the conveyor. When the slats are rotated to the sprocket, the gap becomes larger and the retained powdery debris falls from the gap, avoiding the problem in the prior art that debris falls from the gap between the slats, thereby affecting the life of the chain and sprocket.

[0030] A second embodiment of a conveyor of the present invention is as follows: Figure 7As shown, the only difference from the first embodiment is that the structure of the slats is different. In this embodiment, the carrier substrate is provided with raised reinforcing ribs 15 on the conveying surface. The reinforcing ribs can be integrally pressed or subsequently welded. In this embodiment, the reinforcing ribs 15 are integrally pressed and formed into a triangle. In other embodiments, the reinforcing ribs can also be trapezoidal or other shapes. When conveying some relatively smooth materials, such as logs, metals, etc., when there is no requirement for the flatness of the conveying surface of the conveyor, the above-mentioned reinforcing ribs can be well applied to the above situation to improve the friction and overall strength of the slat conveying surface.

[0031] A third embodiment of a conveyor of the present invention is as follows: Figure 8 As shown, the only difference from the first embodiment is that both ends of each slat are provided with a closure plate 16 on the conveying surface to prevent the conveyed material from entering the chain.

[0032] A fourth embodiment of a conveyor of the present invention is as follows: Fig. 9 As shown, the only difference from the first embodiment is that a load-bearing roller 17 is provided between the first arc-shaped matching portion and the second arc-shaped matching portion on the carrier substrate, and the load-bearing roller 17 and the first arc-shaped matching portion and the second arc-shaped matching portion are located on the same side of the carrier substrate. At this time, a track for supporting and matching the load-bearing roller 17 is provided between the two roller chains on the frame, so that the load-bearing roller 17 is always in contact with and supported by the load-bearing roller 17 during the entire movement process, so as to improve the load capacity of the slat, which is suitable for conveying some relatively heavy materials while requiring the conveying surface to be flat. The load-bearing roller can be connected to the carrier substrate by welding, riveting, screws, etc.

[0033] A fifth embodiment of a conveyor of the present invention is as follows: Figure 10-12 As shown, the only difference from the first embodiment is that an arc-shaped buffer wear-resistant sheet 4 is concentrically arranged between the first arc-shaped matching part and the second arc-shaped matching part of two adjacent slats. It is suitable for some occasions with strict noise requirements, or working conditions with higher requirements on the sealing of the conveying surface of the conveyor. The arc-shaped buffer wear-resistant sheet is made of plastic or rubber, and is connected to the inner side of the first arc-shaped matching part by bonding or clamping. Its function is that since the slats are mostly metal slats, the arc-shaped buffer wear-resistant sheet is set to avoid the metal slats from contacting and rubbing with each other, causing large noise, and at the same time fill the bottom gap of the gap, improve the sealing performance here, and reduce the possibility of dust and debris passing through the gap into the conveyor.

[0034] The structure of an embodiment of a conveyor chain assembly of the present invention is the same as that of the conveyor chain assembly in each embodiment of the above-mentioned conveyor, and will not be described in detail here.

[0035] An embodiment of a conveyor slat of the present invention has the same structure as the slats in each embodiment of the above-mentioned conveyor, and will not be described again here.
