Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically a single-beam coaxial multi-stage synchronous belt conveyor. Background Technology

[0002] Existing conveyor mechanisms mostly employ, for example... Figure 1 The structure shown is as follows: bearings 02 are installed at both ends of the conveyor shaft 01, and the conveyor shaft 01 is rotatably supported by the bearings 02 at both ends. One end of the conveyor shaft 01 is connected to the power unit 03, and a pulley is fixedly installed in the middle part of the conveyor shaft 01. A conveyor belt 04 is wrapped around the pulley, and the conveyor belt 04 realizes material conveying.

[0003] The above structure has shortcomings: some material conveying lines are relatively long, and the single-stage conveyor belt 04 structure is prone to insufficient tension of the conveyor belt 04. Therefore, it is often necessary to form a material conveying line with multiple-stage conveyor belt 04 structures. At the same time, seamless connection of conveying is required. However, if the above structure is used, if two adjacent conveyor belts 04 are installed on the same conveyor shaft 01, the adjacent conveyor belt 04 belt groups will interfere when tensioned. If the adjacent conveyor belt 04 belt groups are connected by a cross pattern device, the handover transition section structure is complicated, and disassembly, assembly and maintenance are very inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a single-beam coaxial multi-stage synchronous belt conveyor.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A single-beam coaxial multi-stage synchronous belt conveyor includes a frame, on which a plurality of parallel mounting shafts are fixedly mounted. The mounting shafts are rotatably connected to a first pulley group and a second pulley group. The first pulley group includes two first pulleys respectively disposed at both ends of the mounting shaft, and the second pulley group includes two second pulleys respectively disposed at both ends of the mounting shaft. The second pulleys are disposed outside the first pulleys and are independently disposed from the first pulleys.

[0007] Two synchronous belts are connected between two adjacent mounting shafts via the same pulley set, thus forming a primary synchronous belt conveyor mechanism. The primary synchronous belt conveyor mechanism is equipped with a set of drive mechanisms, which include a motor and a gearbox. The output end of the gearbox includes two output shafts located on both sides. The two output shafts are respectively fixedly connected to power pulleys, and the two power pulleys are connected to the two synchronous belts of the primary synchronous belt conveyor mechanism.

[0008] In the above structure, the synchronous belts of adjacent synchronous belt conveyor mechanisms do not cross and are transmitted coaxially. Each synchronous belt conveyor mechanism can be adjusted independently without interfering with each other. The belt group replacement and tensioning are simple and easy.

[0009] The frame is connected to a tensioning mechanism, which includes a tensioning shaft that is detachably connected to the frame. Two tensioning wheels are respectively provided at both ends of the tensioning shaft. The tensioning wheels are located on the outside of the synchronous belt, and each stage of the synchronous belt conveyor is provided with at least one tensioning mechanism.

[0010] A belt support bracket is fixedly connected to the frame, and the timing belt can slide along the upper surface of the belt support bracket, thereby providing support for the timing belt.

[0011] A raised guide strip is provided on the inner center of the synchronous belt.

[0012] The surfaces of the belt support bracket that contact the timing belt, the outer surfaces of the first pulley and the second pulley are all provided with grooves. The grooves are matched with the shape of the guide strip and slide in fit, thereby ensuring that the timing belt will not deviate when there is a slight error in its installation.

[0013] The upper part of the frame is connected to the support bracket via multiple mounting beams.

[0014] The beneficial effects achieved by this utility model are:

[0015] This utility model uses a single beam with two sets of independent pulleys coaxially installed, so that the two adjacent synchronous belts do not cross and can achieve seamless material conveying.

[0016] The drive mechanism of this utility model is installed at the lower part of the mounting shaft, and each stage of the synchronous belt conveyor is provided with at least one tensioning mechanism. Each stage of the synchronous belt conveyor can be adjusted independently without interfering with each other. The replacement and tensioning of the synchronous belt of each stage of the synchronous belt conveyor is simple and easy.

[0017] The timing belt of this invention can be equipped with guide strips, and grooves are matched between the middle of the pulley and the belt support to ensure that the timing belt does not run off-center. Attached Figure Description

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example:

[0029] like Figures 2-7 As shown, a single-beam coaxial multi-stage synchronous belt conveyor includes a frame 1, on which multiple parallel mounting shafts 2 are fixedly mounted, and the mounting shafts 2 are horizontally positioned. Figure 6 As shown, the mounting shaft 2 is rotatably connected to a first pulley group and a second pulley group via bearings. The first pulley group includes two first pulleys 12 respectively located at both ends of the mounting shaft 2, and the second pulley group includes two second pulleys 3 respectively located at both ends of the mounting shaft 2. The second pulleys 3 are located outside the first pulleys 12 and are independently configured. The second pulleys 3 and the first pulleys 12 are used to connect the synchronous belts 6 of adjacent stages.

[0030] Two synchronous belts 6 are connected between two adjacent mounting shafts 2 via one of the pulley sets, thus forming a primary synchronous belt conveyor mechanism. The two synchronous belts 6 move synchronously to transport materials. The two synchronous belts 6 are respectively located on both sides of the frame 1.

[0031] The primary synchronous belt conveyor is equipped with a set of drive mechanisms, which include a motor 8 and a reduction gearbox 9. The output end of the reduction gearbox 9 includes two output shafts on both sides. The two output shafts are respectively fixedly connected to power pulleys 10. The two power pulleys 10 are connected to the two synchronous belts 6 of the primary synchronous belt conveyor.

[0032] Gearbox 9 uses a dual-output-shaft reducer.

[0033] The frame 1 is connected to a tensioning mechanism, which includes a tensioning shaft 11. The tensioning shaft 11 is horizontally arranged and detachably connected to the frame 1. Two tensioning wheels 4 are respectively arranged at both ends of the tensioning shaft 11. The tensioning wheels 4 are arranged on the outside of the synchronous belt 6, and each stage of the synchronous belt conveyor is provided with at least one tensioning mechanism.

[0034] The upper part of the frame 1 is connected to the support bracket 5 by multiple mounting beams 7, and the timing belt 6 can slide along the upper surface of the support bracket 5, thereby providing support for the timing belt 6.

[0035] like Figure 6 , Figure 7 As shown, a raised guide strip 13 is provided in the middle of the inner side of the synchronous belt 6. The surface of the belt support bracket 5 that contacts the synchronous belt 6, the outer surface of the first pulley 12, and the outer surface of the second pulley 3 are all provided with grooves. The grooves are shaped and slidably fitted with the guide strip 13, thereby ensuring that the synchronous belt 6 will not deviate when there is a slight error in its installation.

[0036] One implementation method is given to illustrate the specific structure, such as... Figure 2 , Figure 4 As shown, the overall structure includes four mounting shafts 2 and a three-stage synchronous belt conveyor mechanism. The first mounting shaft 2 and the second mounting shaft 2, the second mounting shaft 2 and the third mounting shaft 2, and the third mounting shaft 2 and the fourth mounting shaft 2 form the basic structure of the three-stage synchronous belt conveyor mechanism.

[0037] Looking from left to right, in the first-stage synchronous belt conveyor mechanism, the first-stage synchronous belt 6 is connected to the second pulley 3 of the first mounting shaft 2 and the second mounting shaft 2; in the second-stage synchronous belt conveyor mechanism, the second-stage synchronous belt 6 is connected to the first pulley 12 of the second mounting shaft 2 and the third mounting shaft 2; in the third-stage synchronous belt conveyor mechanism, the third-stage synchronous belt 6 is connected to the second pulley 3 of the third mounting shaft 2 and the fourth mounting shaft 2.

[0038] The three-stage synchronous belt conveyor uses three sets of drive mechanisms, and the power pulley 10 of the drive mechanism is connected to the two synchronous belts 6 of the synchronous belt conveyor.
