Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, in particular to a material flow diversion device with adjustable proportion. Background Art

[0002] In the existing technology, the belt conveyor has only a single conveying function. When the amount of items transported is large, it is easy to cause items to pile up, causing trouble for sorting personnel and reducing work efficiency.

[0003] Publication number CN113682784A discloses an intelligent belt conveyor with a multi-point blanking function, belonging to the technical field of belt conveyors. The intelligent belt conveyor with a multi-point blanking function comprises a screening mechanism for removing defective products, a multi-point blanking mechanism disposed at one end of the screening mechanism, a rotating mechanism coaxially disposed outside the multi-point blanking mechanism, and a bracket for supporting the screening mechanism and the multi-point blanking mechanism. When sufficient personnel are available, the first and second ring plates do not rotate, allowing multiple workers to directly sort items, improving sorting efficiency. When insufficient personnel are available, the workers stand on the same side, the second motor starts, and the rotating rod drives the gear to rotate. The gear drives the first and second ring plates via the outer ring gear, ensuring that all items pass the workers and preventing items from being missed. When the height sensor detects that the worker is short, the bending cylinder moves downward to the fourth conveyor below, making it easier for shorter employees to sort items.

[0004] The above technical solution has some problems in practical application. Although the technical solution can realize multi-point blanking of products, it cannot realize the screening and individual blanking of products. During the production and transportation process, it is often necessary to screen and blank the products according to the weight of the materials.

The guide plate can move in the gap, thereby realizing the transfer of materials above the feed conveyor belt. The materials can be weighed during the transfer process. The weighing of the materials will not be affected by the external environment, thereby effectively ensuring the detection accuracy of the device for the material weight, and further ensuring the material separation accuracy of the device;

[0035] 3. The present invention arranges a support plate and a movable plate below the guide plate. The support plate, the movable plate and the guide plate form a parallelogram structure.

[0048] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment, and no special limitation is made in this embodiment.

[0049] In this embodiment, a material flow dividing device with adjustable ratio includes:

[0050] A material distribution tee 1 is provided with a feed port at the top and two symmetrically distributed discharge ports at the bottom;

The pneumatic push rod 13 can push the swing arm 12 to drive the distribution barrel 11 to rotate.

[0053] There are two groups of feed conveyor belts 2, both of which are located above the material distribution tee 1.

[0059] The transmission shaft 45 is located at the bottom end of the movable arm 43 and is rotatably disposed inside the support frame 5;

[0060] The transmission shaft 45 can drive the guide plate 4 to swing through the movable arm 43 and the support arm 42. The guide plate 4 can move between the two feed conveyor belts 2 to achieve material transfer. The guide plate 4 moves between the two feed conveyor belts 2 in an intermittent motion manner.

[0061] A drive shaft 47 is located between the two transmission shafts 45 and is rotatably disposed inside the support frame 5;

[0062] The transmission gear 46 and the drive gear 48 are located at one end of the transmission shaft 45 and the drive gear 48 is located at one end of the drive shaft 47 , and the drive gear 48 is meshed with the transmission gear 46 ;

[0063] The worm gear 471 and the worm 472 are located in the middle of the drive shaft 47, and the worm 472 is located inside the support frame 5 and meshes with the worm gear 471. A stepper motor 473 is provided at one end of the worm 472, and the stepper motor 473 is located inside the support frame 5. The stepper motor 473 can drive the movable arm 43, and when the movable arm 43 is perpendicular to the ground, the stepper motor 473 can temporarily stop working to facilitate product weighing;

[0064] A support frame 5 located outside the feed conveyor belt 2;

[0065] The active roller 6 is located at one end of the inner portion of the support frame 5;

[0066] The feed motor 62 is located inside the support frame 5. The output shaft of the feed motor 62 is connected to one end of the active roller 6 through a reduction gear set 63. The feed motor 62 can realize intermittent driving of the feed conveyor belt 2.

[0067] There are multiple driven rollers 7, which are respectively located on the inner sides of multiple feed conveyor belts 2. The outer side of the active roller 6 is provided with multiple grooves 61 corresponding to the feed conveyor belts 2. The grooves 61 can ensure the stability of the active roller 6 in guiding the feed conveyor belt 2. Both sides of the driven roller 7 are rotatably provided with support arms 71 through bearings, and the support arms 71 are located inside the support frame 5. The support arms 71 can support the driven roller 7;

[0068] A base 8 is provided below the material dividing tee 1, the feeding conveyor belt 2 and the unloading conveyor belt 3, and the base 8 can support the above components.

[0069] When using a material adjustable ratio diversion device of this embodiment, the material can be transported through the feed conveyor 2. When the material moves to one end of the feed conveyor 2, the feed conveyor 2 stops moving. At this time, the stepping motor 473 drives the drive shaft 47 to rotate through the worm 472 and the worm gear 471. The drive shaft 47 drives the transmission shaft 45 to rotate through the drive gear 48 and the transmission gear 46. The transmission shaft 45 can drive the movable arm 43 to rotate. The movable arm 43, the support arm 42 and the guide plate 4 form a parallelogram structure. When the movable arm 43 and the support arm 42 are connected, the movable arm 43 and the support arm 42 are connected. When the support arm 42 rotates following the transmission shaft 45, the guide plate 4 moves between the two sets of feed conveyor belts 2. At this time, the guide plate 4 can move the material from one set of feed conveyor belts 2 to the other set of feed conveyor belts 2. During this process, when the material follows the guide plate 4 to move between the two sets of feed conveyor belts 2, the stepper motor 473 stops working temporarily. At this time, the movable arm 43 and the support arm 42 are both perpendicular to the ground. At this time, the material generates downward pressure on the guide plate 4 under the action of gravity, and the weighing sensor 44 can detect this downward pressure to achieve the effect of detecting the weight of the product;

[0070] After the product weight detection is completed, the pneumatic push rod 13 can drive the swing arm 12 to move, so that the swing arm 12 drives the distribution barrel 11 to rotate, so that the discharge port at the bottom end of the distribution barrel 11 switches between the two discharge ports at the bottom end of the distribution tee 1. After the weighing is completed, the product follows the feed conveyor belt 2 to fall into the distribution tee 1, and the distribution is completed under the guidance of the distribution barrel 11. The product after distribution can be transferred by the unloading conveyor belt 3.

[0071] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
