Description

Technical Field

[0001] The utility model relates to a chain plate conveyor, in particular to a chain plate structure of the chain plate conveyor. Background Art

[0002] Chain conveyors are often used for conveying materials. For example, in food production and chemical production, chain conveyors can be used to transport production to corresponding processing equipment. Chain conveyors generally include an equipment frame, two chains set on the equipment frame, and multiple placement plates set on the links of the two groups of chains in sequence. The multiple placement plates on some chain conveyors are separated. When these placement plates move to the horizontal part above the chain, the edges fit together for material placement. The multiple placement plates on some chain conveyors are hinged together head to tail in sequence, and the hinge points are then connected to the hinge points of the links on the chain in sequence. Multiple placement plates and two groups of chains are assembled into a chain structure. For this type of chain conveyor, it is very inconvenient to remove the chain structure from the chain conveyor, which also affects repair and maintenance. Utility Model Content

[0030] See also Figure 1 and Figure 2 A chain plate structure of a chain plate conveyor comprises a plurality of placement plates 1, a plurality of groups of first connecting pins 2, a group of second connecting pins 3 and two chains 4.

[0031] See also Figure 2 , Figure 4 and Figure 5 , a plurality of first protrusions 1a are arranged on the first side edge of each placement board 1, and a second protrusion 1b is arranged on the opposite second side edge corresponding to the empty space between two adjacent first protrusions 1a. In this way, when the plurality of placement boards 1 are connected end to end to complete the closing, for the first connection between two adjacent placement boards 1, the second protrusion 1b enters the empty space between two adjacent first protrusions 1a.

[0032] Multiple groups of first connecting pins 2 and a group of second connecting pins 3 are sequentially arranged at the first connection points of two adjacent placement plates 1 to complete the hinge connection of two adjacent placement plates 1. That is, the first protrusions 1a and the second protrusions 1b are both provided with through holes, and a group of first connecting pins 2 or a group of second connecting pins 3 penetrate into all the first protrusions 1a and the second protrusions 1b corresponding to a first connection point. In addition, after a group of first connecting pins 2 or a group of second connecting pins 3 are connected to the first connection point, both outer ends extend beyond the placement plate 1 for subsequent chain 4 to be connected.

[0033] For any group of first connecting pins 2, the number can be one, that is, this first connecting pin 2 penetrates into all the first protrusions 1a and the second protrusions 1b corresponding to a first connection, and finally both ends of this first connecting pin 2 exceed the placement plate 1; the number can also be two, that is, the two first connecting pins 2 enter from both sides respectively, and finally the outer ends of the two first connecting pins 2 exceed the placement plate 1.

[0034] For this group of second connecting pins 3, the number must be two. The two second connecting pins 3 can be adjusted in the axial position at the first connection. Specifically, a screw 1c can be threadedly connected to the corresponding first protrusion 1a or the second protrusion 1b. By tightening the screw 1c and squeezing the second connecting pin 3, it can be relatively fixed. By loosening the screw 1c, the second connecting pin 3 can be moved. By moving the two second connecting pins 3, the two outer ends can also be retracted to separate from the outermost first protrusion 1a, that is, the length of the two second connecting pins 3 needs to be set, and a sufficient interval needs to be reserved between the two second connecting pins 3.

[0035] When the two outer ends of the second connecting pins 3 are retracted to separate from the outermost first protrusions 1a, the two placement plates 1 of the first connection can be separated. Specifically, for the first connection, the two outermost first protrusions 1a are normally provided with through holes, and the remaining first protrusions 1a are processed separately, the lower part is removed, and half of the through hole is left to cooperate with the second connecting pins 3.

[0036] See also Figure 3 and Figure 4 Two chains 4 are respectively arranged on both sides of the plurality of placement plates 1. Correspondingly, after the chain plate structure is installed on the chain plate conveyor, the frame of the chain plate conveyor is provided with a shielding part 6 to shield the chains 4 on both sides and the edge parts of both sides of the chain plate structure.

[0037] The second connection points of two adjacent chain links 4a are sequentially connected to the outer ends of the first connecting pin 2 and the second connecting pin 3 that extend beyond the placement plate 1. Specifically, the two chain links 4a can be connected by a connecting sleeve 4b, both ends of which can be riveted, and the connecting sleeve 4b is sleeved onto the corresponding outer ends, and a nut 3a is threadedly connected to the portion of the outer end that passes through the connecting sleeve 4b.

[0038] When the outer ends of the second connecting pins 3 of the group are retracted to be separated from the corresponding two chain links 4a, the two chain links 4a can be separated. Specifically, the two ends of the connecting sleeves 4b on the two chain links 4a do not need to be riveted. In this way, first screw out the nuts 3a corresponding to the connecting sleeves 4b on the two chain links 4a; then move the two second connecting pins 3; and finally pull out the connecting sleeves 4b, and the two chain links 4a can be separated.

[0039] Obviously, the outer ends of the second connecting pins 3 will be separated from the chain link 4a before they are retracted to separate from the outermost first protrusions 1a. Therefore, after the outer ends of the second connecting pins 3 of this group are retracted to separate from the outermost first protrusions 1a, the closed plate chain structure can be disassembled.

[0040] See also Figure 6 Optionally, the chain plate structure further includes a driving mechanism 5. There are two placement plates 1 connected to the two second connecting pins 3, and the driving mechanism 5 is disposed on one of the two placement plates 1 to drive the two second connecting pins 3 to slide axially.

[0041] See also Figure 6 and Figure 7 Furthermore, the driving mechanism 5 uses a bidirectional screw module. Specifically, the bidirectional screw module includes a mounting frame 5a, a bidirectional screw 5b and two mounting slide blocks 5c. The two mounting slide blocks 5c are slidably connected to the mounting frame 5a. The bidirectional screw 5b is rotationally connected to the mounting frame 5a, and the matching screw nuts 3a on the two threaded parts are respectively fixedly connected to the two mounting slide blocks 5c. The two second connecting pins 3 are respectively connected to the two mounting slide blocks 5c, so that the mounting slide blocks 5c can slide together with the connecting pins. The bidirectional screw 5b can be rotated manually or driven by a motor. Because the chain plate structure needs to move cyclically, if a motor is used for driving, it can be powered by a battery, and the battery and the bidirectional screw module are arranged on the placement plate 1 together.

[0042] See also Figure 7 and Figure 8 Furthermore, the driving mechanism 5 further includes a rotating shaft 5d and a bevel gear set 5e, that is, the bidirectional screw 5b is manually rotated. The rotating shaft 5d is rotatably connected to the mounting frame 5a of the bidirectional screw module. The bevel gear set 5e is arranged between the rotating shaft 5d and the bidirectional screw 5b, and transmits the rotation of the rotating shaft 5d to the bidirectional screw 5b. The placement plate 1 for the driving mechanism 5 is provided with a through hole and a plug 1d inserted into the through hole at a position corresponding to the rotating shaft 5d.

[0043] In this way, in normal use, the top surface of the plug 1d and the top surface of the placement plate 1 form a complete placement surface, which will not affect the placement of materials on the placement plate 1. When the plate chain structure needs to be disassembled, the plug 1d can be removed, and the rotating shaft 5d can be rotated by a screwdriver to drive the bidirectional lead screw 5b to rotate, thereby driving the two second connecting pins 3 to slide.

[0044] Optionally, at least one of the two placement plates 1 connected by the second connecting pin 3 is marked, so that when the plate chain structure needs to be disassembled, the position of the second connecting pin 3 can be found more conveniently and intuitively. The mark can be a different color of the placement plate 1, or a sticker attached to the placement plate 1. When the above-mentioned "driving mechanism 5 also includes a rotating shaft 5d and a bevel gear set 5e" is adopted, the plug 1d can be used as a mark.
