Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor equipment, in particular to a belt conveyor device and a color sorter thereof. Background Art

[0002] Traditional color sorter belt conveyor (such as Figure 7 As shown): It is composed of a prior art transmission frame 100, a prior art drive shaft 200, a prior art driven shaft 300, a prior art power device 400, a prior art load-bearing plate 500, and a prior art belt 600. The prior art transmission frame 100 is used to fix various components. The prior art belt 600 is tensioned by the prior art driven shaft 300 and the prior art drive shaft 200, and the upper belt surface is lifted by the prior art load-bearing plate 500. The prior art power device 400 drives the prior art drive shaft 200 to rotate, and the prior art drive shaft 200 drives the prior art belt 600 to rotate to reach the designed linear speed. The material to be tested enters from the side of the prior art drive shaft 200, and after being accelerated by the prior art belt 600, it is relatively stationary with the prior art belt 600. It is then thrown out from the side of the prior art driven shaft 300 and enters the detection area. However, the following disadvantages still exist in actual use:

[0003] 1. With the development of color sorters, the sorting materials are becoming more and more complex, and the material particles are getting larger and larger. The belt surface of the above-mentioned belt conveyor is flat, and large block materials will roll, and it is impossible to ensure that they are relatively still with the belt before being thrown out;

[0004] 2. The market's demand for output has increased, resulting in wider belt conveyors and an increase in the length of the driven shaft. However, due to the limitations of the color sorter's recognition principle, the shaft diameter cannot be increased, which poses a challenge to the rigidity of the shaft.

[0005] 3. The belt conveyor components configured for machines of different widths are not universal, which increases inventory and management costs. Utility Model Content

[0006] The purpose of the utility model is to provide a belt conveyor device to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A belt conveyor device includes a crossbeam, a plurality of side plates are equidistantly arranged along the length direction of the crossbeam, a driven shaft is rotatably arranged between adjacent side plates, a plurality of belts are wrapped around the driven shaft and arranged axially along the driven shaft, and a support plate is arranged under each group of belts for support and to prevent objects from moving to the sides of the belts.

[0009] Preferably, it also includes a driving shaft passing through the side plate, the driving shaft is circumferentially connected to each group of the belts, and the end of the driving shaft is transmission-connected to the reduction motor.

[0010] Preferably, a roller in contact with the belt is rotatably provided between adjacent side plates for changing the belt transmission direction, and the roller is located on one side of the driving shaft.

[0011] Preferably, a plurality of brackets are provided in the length direction of the crossbeam, and a tensioning wheel which is rotatably provided on the bracket and in close contact with each belt for adjusting the belt tension, and the bracket and the tensioning wheel are located on the other side of the driving shaft.

[0012] Preferably, a plurality of groups of fixed beams are arranged between adjacent side panels, and the support plates are arranged on the fixed beams.

[0013] Preferably, ribs for limiting position are provided on the back side of the belt.

[0014] Preferably, two sides of the support plate are higher than the middle thereof, thereby forming a downwardly concave structure.

[0015] The utility model also provides a color sorter, comprising the belt conveyor device described above.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model can effectively prevent the material from rolling left and right by setting the supporting plate of the supporting belt to be higher on both sides than in the middle, thereby forming a groove with a low middle and high sides;

[0018] 2. The transmission frame is no longer welded as a whole, but is assembled by side plates, crossbeams, support plates and other parts. The width of the belt conveyor can be easily increased by increasing the number of side plates, crossbeams, support plates and driven shafts, without increasing the diameter of the driven shaft;

[0019] 3. The entire belt conveyor device is composed of individual belt conveyor channels. Therefore, when the width of the entire device is adaptively adjusted, the components of each channel can be used universally, effectively reducing the procurement and management costs of components during the production process.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 -7. The utility model provides a technical solution:

[0030] A belt conveyor device comprises a cross beam 1, and a plurality of side panels 2 are arranged equidistantly along the length direction of the cross beam 1. In the technical solution of this embodiment, the side panels 2 are inverted trapezoidal structures, and are provided with three groups in total, namely, the side panels on both sides and the middle side panels in the middle, and the specific number thereof can be set according to the width of the conveyor device in actual application; a driven shaft 3 is rotatably arranged between adjacent side panels 2 through a mounting seat, and by arranging the driven shaft with a longer length in the prior art into a plurality of laterally arranged driven shafts 3, when the width of the entire conveyor device needs to be adjusted, it is only necessary to adjust the number of the driven shafts 3, thereby avoiding the disadvantage of reducing its strength due to increasing the length of the driven shaft; the driven shafts 3 are respectively located at At both ends of the side plates 2, multiple groups of belts 4 are wrapped around the driven shaft 3 and arranged axially along the driven shaft 3. In the technical solution of this embodiment, a total of eight groups of belts 4 are provided, and each group of belts 4 constitutes a conveying channel. By arranging the entire belt in the prior art into multiple groups of single, narrow belts 4, it is convenient to adjust the width of the entire conveying device. More importantly, the parts of each belt 4 channel can be universal, which effectively reduces the procurement and management costs of parts in the production process; a support plate 5 for support is provided under each group of belts 4 to prevent objects from moving to both sides of the belt 4. Multiple groups of fixed beams 11 are provided between adjacent side plates 2, and the support plates 5 are provided on the fixed beams 11;

[0031] It also includes a drive shaft 6 that passes through the side plate 2. The drive shaft 6 is connected to each group of belts 4 in a circumferential manner. The end of the drive shaft 6 is connected to the reduction motor 7 in a transmission manner. In the technical solution of this embodiment, the reduction motor 7 is composed of a motor and a reducer. Specifically, the power input end of the motor is connected to the power input end of the reducer, and the power output end of the reducer is connected to the drive shaft 6, thereby driving it to rotate, and finally driving each belt 4 to rotate synchronously;

[0032] A roller 8 in contact with the belt 4 is rotatably provided between adjacent side plates 2 for changing the transmission direction of the belt 4. The roller 8 is located on one side of the driving shaft 6.

[0033] Multiple groups of brackets 9 are installed by bolts along the length direction of the crossbeam 1. The number of brackets 9 is consistent with the number of belts 4, which are both eight groups. A tensioning wheel 10 that is in close contact with each belt 4 and is used to adjust the tension of the belt 4 is rotatably provided on the bracket 9. The bracket 9 and the tensioning wheel 10 are located on the other side of the drive shaft 6, so that the belt 4 can be tightly wrapped around the drive shaft 6 to avoid slipping between the drive shaft 6 and the belt 4 during rotation; by adapting a group of tensioning devices to each belt 4, it is effectively avoided that the lengths of the belts 4 are different and the tension amounts are different;

[0034] In order to prevent the belt 4 from being skewed during the transmission process, a rib for limiting the position is provided on the back of the belt 4, and corresponding grooves are provided on the driven shaft 3, the support plate 5 and the driving shaft 6, and the ribs on the belt 1 are clamped in the grooves;

[0035] In order to prevent the materials transported on the belt 4 from moving to the left and right and sliding down, the two sides of the support plate 5 are higher than the middle thereof, thereby forming a downwardly concave structure.

[0036] The utility model also provides a color sorter, comprising the above-mentioned belt conveyor device.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
