Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 shows a schematic view of the structure of a chain link.

In the figure: 1. a chain link; 11. a rotating shaft; 12. a chain plate; 121. a limiting hook; 13 supporting rods; a 131 clamping part; 132. a roller; 2. a track; 21. a relief portion.

Detailed Description

Referring to fig. 1 and 2, a reduce and pile up conveyer belt, including sprocket (not shown), walk around the chain (not shown) of sprocket and connect the chain link 1 of chain, chain link 1 is connected by pivot 11 and one end chain joint 12 in the pivot 11 constitutes, the spacing hook 121 of one-level echelonment is bent into to the other end of chain joint 12, the both sides of pivot 11 respectively connect one the chain, it is adjacent chain link 1 relies on with pivot 11 to the range order of spacing hook 121 the chain is fixed to constitute the conveyer belt and goes back to the ring, the bottom surface of chain joint 12 is provided with bracing piece 13, is provided with in the conveyer belt goes back to the ring and is used for guiding bracing piece 13 produces undulant track 2.

In the process of blanking the special-shaped workpieces to the conveying belt from the storage bin, the special-shaped workpieces may be slightly hooked with each other, so that the number of the workpieces discharged from the storage bin in unit time is not even, the workpieces are more, less and more, and the workpieces are stacked on the conveying belt. Adopt the utility model discloses a reduction piles up the conveyer belt after, when the link joint drives the bracing piece and reachs the hillside department on the track, the link joint uses the pivot to be the fulcrum by bracing piece jack-up, inclines backward, piles up and builds the work piece of height on the link joint and just topples over backward very easily, and the work piece that does not pile up only can backward move a segment distance, takes place the many times back that fluctuates at the link joint, only remains the individual layer work piece on the link joint basically, greatly reduces the emergence of piling up, is favorable to follow-up surface treatment abundant, even.

In order to sufficiently shake off the stacked workpieces, the undulations 21 on the rails 2 should have more than two.

The track 2 guides the support rod 13 to undulate in two ways including, but not limited to:

firstly the lower extreme of bracing piece 13 is provided with the slider, track 2 is the straight slide rail that just has local undulation in the middle of the both ends for the circular arc. The slide block slides on the slide rail under the driving of the chain, and when the slide block moves to a local fluctuation position, the support rod 13 jacks up the chain plate 12. The sliding rail should be a complete loop, and the sliding block always slides on the sliding rail. This arrangement is highly stable but has high friction and high link stiffness when the belt is steered.

Secondly, the lower end of the supporting rod 13 is provided with a roller 132 which is rotatably connected with the supporting rod 13, and the track 2 is a platform with two ends being cambered surfaces, the middle of which is straight and has local fluctuation. Under the drive of the chain, the roller 132 rolls on the platform, and the support rod 13 jacks up the link plate 12 when the roller 132 travels to the local undulation. The platform may be discontinuous to save space, save material. The rollers 132 contact the platform only where the links travel to the upper portion of the belt and turn, and remain stationary on the axles of the next link by virtue of the spacing catches of the previous link as the links travel to the lower portion of the belt.

Must, the utility model discloses a reduction piles up the conveyer belt and still includes frame and motor, and the sprocket rotatably sets up in the frame, and the output of motor is connected with the axle center of a sprocket, and the frame stretches into the conveyer belt loop in with trapped orbit 2 from the both sides of conveyer belt.

The limiting hooks 121 have double functions, in order to enable the chain plates 12 to incline as much as possible, the supporting rods 13 should be made as long as possible, each chain link is only connected with the chain at the position of the rotating shaft 11, one of the limiting hooks 121 serves as the inclining limit of the chain plates 12 and is clamped below the rotating shaft of the previous chain link, the completeness and continuity of the conveyor belt are guaranteed, and the second function is to prevent a workpiece from being separated from the space between the two chain links when the chain plates 12 incline. Since the support rods 13 should be as long as possible, there is a slight length difference between the support rods 13, in order to reduce the rigidity of the support rods 13 at the undulated positions and the turning positions of the track, the support rods 13 are telescopic, the lower ends of the support rods 13 are provided with the clamping portions 131, and compression springs are arranged between the clamping portions 131 and the chain plates 12 and sleeved on the peripheries of the support rods 13. Besides, the undulation height on the track 2 is not larger than the depth of the limit hook 121, the width of the limit hook 121 is not larger than the diameter of the rotating shaft 11, and the rigidity of the support rod 13 at the undulation position and the turning position of the track can also be reduced. It should be noted that while the proportion of all the links is exaggerated in fig. 1 for clarity of construction, the links should actually be more and less, and an excessive proportion of links relative to the sprocket would increase the stiffness in steering.

The top of the rotating shaft 11 is higher than the top surface of the chain plate 12, when the chain plate 12 inclines, the rotating shaft 11 prevents the workpieces from sliding backwards, namely, the workpieces stacked on the upper layer can topple backwards, and the workpieces positioned at the bottommost layer cannot slide backwards, so that the workpieces on the upper layer can topple backwards more easily, and the conveying efficiency of the conveyor belt is ensured.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and decorations can be made without departing from the principle of the invention, and these modifications and decorations are also regarded as the protection scope of the present invention.
