Detailed Description
The invention will be described in detail below with reference to the drawings in connection with embodiments. It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" are used hereinafter to denote only the directions corresponding to the upper, lower, left, and right directions of the drawings, and do not limit the structure.
Example 1
As shown in fig. 1, 2 and 3, the conveying system provided in this embodiment includes a chain 1, a sprocket 2 and a feeding platform 3.
The chain 1 includes a plurality of links 13 alternately connected to at least one pair of outer link plates 11 and/or one pair of inner link plates 12, and a bendable structure formed by pin shafts 14 end to end. The chain 1 may be a roller chain or a bush chain.
The outer link plate 11 and the inner link plate 12 each include a placement surface 101, a forward surface 102 and a reverse surface 103 extending from both ends of the placement surface 101 in a bent manner, and an engagement surface 104 connected between the forward surface 102 and the reverse surface 103. The advancing surface 102 is the front surface of the moving direction by taking the moving direction of the chain as a reference, and the reverse surface 103 is the reverse surface; the upper ends of the outer link plate 11 and the inner link plate 12 are carrying surfaces 101, whereas the lower ends are engaging surfaces 104.
As shown in fig. 2, the radius or distance r1 from the pin center of the outer link plate 11 and/or the inner link plate 12 to the forward surface (102) and/or the reverse surface (103) is greater than 1/2 of the link plate height h or the distance a from the pin center to the link plate loading surface 101 in design, whereby a protrusion 15 is formed at the front end of the link movement direction at the junction of the loading surface 101 and the forward surface 102 when the chain 1 is in an arc operation. When the chain 1 moves horizontally, the protrusion disappears and the entire chain forms a complete continuous plane, i.e. the loading surface 101 for the material.
In this embodiment, the carrying surface 101 and the engaging surface 104 are both straight-sided structures, and the advancing surface 102 and the retracting surface 103 are both circular arc surfaces.
As shown in fig. 1, the number of the sprockets 2 is at least two, and there may be only one driving wheel. The sprocket 2 engages with the engagement surface 104 of the chain 1 and drives the chain 1 to rotate. The feeding platform 3 is positioned at the opposite side of the movement direction of one of the chain wheels 2 and is flush with the normal direction of the root circle of the chain wheel 2.
The working principle of the conveying system provided by the embodiment is as follows:
as shown in fig. 1, the material 200 is a sheet, is vertically arranged on the feeding platform 3 and is displaced towards the direction of the chain wheel 2, the chain wheel 2 rotates anticlockwise as shown in fig. 1, and the chain 1 moves leftwards;
because the feeding platform 3 is level with the normal direction of the root circle of the chain wheel 2, when the chain link 13 rotates into arc motion from the rotation of the chain wheel 2, the convex points 15 stir the vertically placed material to be horizontally placed on the carrying surface 101 and to be leftwards displaced together with the chain 1, thereby realizing the functions of stirring, discharging and conveying. Since it is necessary to ensure that the material 200 is uniformly and intermittently arranged on the carrying surface 101, the displacement speed of the feeding platform 3 and the rotation speed of the sprocket 2 are related to the external dimension of the material 200, and the speed is adjustable.
As shown in fig. 4, the conveying system further includes a second sprocket system 4, the second sprocket system 4 is disposed above the sprocket system, and a channel 5 for conveying materials is formed between a chain 41 of the second sprocket system 4 and a mounting surface 101 of a chain 1 of the sprocket system. The channel 5 can make the distributed materials tighter and smoother. The chain of the second sprocket system 4 may have the same structure as the chain 1 of the sprocket system, or may be a normal chain. The running speed of the chain can be independently adjusted, so that the discharge density can be adjusted as required.
Example two
The conveying system provided in this embodiment is different from the conveying system provided in this embodiment in that, as shown in fig. 5 and 6, the carrying surface 101 and the engaging surface 104 of the chain 1 are both in straight-sided structures, the advancing surface 102 and the retreating surface 103 are adjacent to the carrying surface 101 and are adjacent to the engaging surface 104 are in circular-arc structures.
As shown in fig. 6, in the design, the radius or the distances r1, r2, r3 from the pin center of the outer link plate 11 and/or the inner link plate 12 to the forward surface (102) and/or the backward surface (103) are larger than 1/2 of the link plate height h or the distance a from the pin center to the link plate mounting surface 101, whereby the protrusion 15 is formed at the connection between the mounting surface 101 and the forward surface 102, i.e., the front end in the moving direction of the chain 1.
In addition, as shown in fig. 7, the conveying system of the present embodiment may also be provided with two sprocket systems, and a channel is formed between the two conveying chains to make the dispensed material tighter and flatter, and its structural principle is the same as that of the first embodiment.
The structure, connection relation and movement principle of other components of the present embodiment are the same as those of the first embodiment.
Example III
The difference between the chain provided in this embodiment and the second embodiment is that, as shown in fig. 8, the connection between the forward surface 102, the backward surface 103 and the carrying surface 101 is provided with a rounded chamfer.
The structure, connection relation and movement principle of other components of the embodiment are the same as those of the embodiment.
Example IV
As shown in fig. 9, in the present embodiment, the mounting surface 101 and the engagement surface 104 have a straight-sided structure, and the forward surface 102 and the backward surface 103 each include a straight-sided portion 105 and an arc portion 106 extending from both ends of the straight-sided portion 105 toward the mounting surface 101 and the engagement surface 104, respectively.
The structure, connection relation and movement principle of other components of the embodiment are the same as those of the embodiment.
Example five
As shown in fig. 10, in the present embodiment, the loading surface 101, the advancing surface 102 and the retreating surface 103 are all straight-sided structures, and the engaging surface 104 is a tooth-shaped structure.
The structure, connection relation and movement principle of other components of the embodiment are the same as those of the embodiment.
Example six
As shown in fig. 11 and 12, the distance a from the pin center to the bearing surface with the protrusions is larger than the distance r4 from the pin center to the bearing surface without the protrusions, that is, the bearing surface of the chain is provided with a step from the advancing surface to the retreating surface, and when the chain is converted from rotary motion to linear motion, the protrusions on the advancing surface are in contact with the material, and the retreating surface is not in contact with the material.
The structure, connection relation and movement principle of other components of the embodiment are the same as those of the embodiment.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present invention.
