Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a flat chain conveying mechanism. Background Art

[0002] With the rapid development of industrial automation, flat chain conveyors have begun to be used more and more widely in various industries. Flat chain conveyors are a kind of mechanical conveying equipment, which is suitable for conveying items of various shapes and sizes. They can not only transport light items such as parts, food packaging and medicine bottles; they can also be used for the transportation of heavy goods such as steel and auto parts. They have become an indispensable part of modern industry.

[0003] The chain tensioning adjustment of the traditional flat chain conveyor relies on the tensioning roller structure installed on the frame, and the tensioning adjustment is inside the frame, which makes later adjustment and maintenance inconvenient. In addition, today's flat chain conveyors are all designed for independent transportation and cannot be integrated with today's roller conveyor lines and belt conveyor lines. When used in combination, it is difficult to synchronize the conveying speed.

[0004] To this end, we propose a flat chain conveying mechanism. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a flat chain conveying mechanism.

[0006] The utility model discloses a flat chain conveying mechanism, comprising a frame, wherein a front sub-frame and a rear sub-frame are respectively installed at the front and rear ends of the frame, a driving roller is rotatably installed on the inner side of the front sub-frame through a seat bearing, a sub-gear is installed on the outside of one end of the driving roller, a driven gear is rotatably installed on the side of the front sub-frame close to the sub-gear, the sub-gear and the driven gear are meshed and driven by a No. 2 chain, and the driven gear is meshed and driven with a rotating roller horizontally mounted on the top of the inner side of the front sub-frame through a No. 3 chain.

[0007] Furthermore, adjustment rails are installed on both sides of the rear sub-frame, and sliders are slidably installed on the two adjustment rails. A driven roller is installed between the sliders on the two adjustment rails through bearings. A horizontally arranged adjustment screw is rotatably installed at the front ends of the two sliders. The two adjustment screws are located on both sides of the rear sub-frame and are threadedly connected to the rear sub-frame.

[0008] Furthermore, a passive gear is installed at one end of the active roller, and the passive gear is transmission-connected to a driving motor installed on the inner side of the front sub-frame through a No. 1 chain.

[0009] Furthermore, drag chain drive wheels are installed at the relative positions of both ends of the active roller and the driven roller, a chain plate drag chain is installed between the drag chain drive wheels on the active roller and the driven roller, and a support plate is installed on each chain link side of the chain plate drag chain through a right-angle frame.

[0010] Furthermore, a load beam is installed via a bracket at the position of the two chain plate drag chains in the middle of the frame, and a roller that rolls with the load beam is installed on the chain link shaft of each chain plate drag chain.

[0011] Furthermore, each of the pads of the frame, the front sub-frame and the rear sub-frame is equipped with an adjusting foot.

[0012] Furthermore, the length of the support plate is adapted to the inner width of the frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model changes the tensioning adjustment design of the traditional plate chain conveyor and combines the tensioning adjustment mechanism with the driven roller, which can effectively simplify the complexity of the tensioning adjustment mechanism of the plate chain conveyor. Moreover, the operating position of the plate chain tensioning adjustment mechanism is located on the side of the conveyor.

DETAILED DESCRIPTION

[0021] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0022] Example:

[0023] The tension adjustment of conventional flat chain conveyors currently relies mainly on the added tension roller assembly, which complicates the equipment structure. Moreover, the adjustment operation end of this type of tension roller mechanism is generally located inside the frame 1, which makes later adjustment and maintenance more troublesome. For this reason, we design a flat chain conveyor that is convenient for later tension adjustment. The specific plan is as follows:

[0024] like Figure 1 , Figure 2 As shown, the present embodiment discloses a flat plate chain conveying mechanism, specifically comprising a frame 1, wherein a front sub-frame 2 and a rear sub-frame 3 are respectively installed at the front and rear ends of the frame 1, a driving roller 8 is rotatably installed on the inner side of the front sub-frame 2 through a seat bearing, and adjusting rails 4 are installed on both sides of the rear sub-frame 3, sliders 6 are slidably installed on the two adjusting rails 4, and a driven roller 5 is installed between the sliders 6 on the two adjusting rails 4 through a bearing, and a horizontally arranged adjusting screw 7 is rotatably installed at the front ends of the two sliders 6, and the two adjusting screws 7 are located on both sides of the rear sub-frame 3 and are threadedly connected to the rear sub-frame 3. In order to realize flat plate chain conveying, a drag chain driving wheel 9 is installed at the relative positions of the two ends of the driving roller 8 and the driven roller 5, a chain plate drag chain 10 is installed between the driving roller 8 and the drag chain driving wheel 9 on the driven roller 5, and a support plate 11 is installed on each chain link side of the chain plate drag chain 10 through a right-angle frame.

[0025] The entire plate chain tensioning adjustment mechanism changes the tensioning adjustment design of the traditional plate chain conveyor and combines the tensioning adjustment mechanism with the driven roller 5, which can effectively simplify the complexity of the tensioning adjustment mechanism of the plate chain conveyor. Moreover, the operating position of the plate chain tensioning adjustment mechanism is located on the side of the conveyor. Compared with the built-in tensioning adjustment mechanism of the conventional plate chain conveyor, the later tensioning adjustment and maintenance are more convenient.

[0026] like Figure 2 , Figure 3 As shown, a passive gear is installed at one end of the active roller 8, and the passive gear is connected to a driving motor 13 installed on the inner side of the front sub-frame 2 through a No. 1 chain 14.

[0027] At the same time, in order to achieve synchronous coordination between the flat chain conveyor and the roller conveyor line, Figure 3 As shown, a sub-gear 15 is installed on the outside of one end of the active roller 8, and a driven gear 16 is rotatably installed on one side of the front sub-frame 2 close to the sub-gear 15. The sub-gear 15 and the driven gear 16 are meshed and transmitted through the No. 2 chain 17. The driven gear 16 is meshed and transmitted with the rotating roller 12 horizontally installed on the top of the inner side of the front sub-frame 2 through the No. 3 chain 18. The driving motor 13 drives the active roller 8 to rotate through the No. 1 chain 14 in cooperation with the passive gear, and the rotation of the active roller 8 synchronously drives the chain plate drag chain 10 and the rotating roller 12 to rotate, thereby realizing the purpose of one machine with multiple uses and achieving the effect of synchronously driving the flat plate chain and the rotating roller 12.

[0028] In order to improve the load-bearing capacity of the flat chain conveyor during operation and ensure that the chain plate drag chain 10 runs more smoothly, such as Figure 4 As shown, a load beam 20 is installed at the position corresponding to the two chain plate drag chains 10 in the middle of the frame 1 through a bracket 19, and a roller 21 that rolls with the load beam is installed on the chain link shaft of each chain plate drag chain 10.

[0029] like Figure 1 , Figure 2 As shown, each foot of the frame 1, the front sub-frame 2 and the rear sub-frame 3 is equipped with an adjusting foot for adjusting the balance of the entire conveying mechanism.

[0030] like Figure 1 , Figure 2 As shown, the length of the support plate 11 is adapted to the inner width of the frame 1. In this design, the two ends of the support plate 11 slide in cooperation with the inner wall of the frame 1, which can effectively prevent the support plate 11 from sliding left and right inside the frame 1, thereby ensuring that the chain plate drag chain 10 always keeps cooperation with the load beam 20.

[0031] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
