[0039] The utility model provides a particulate material conveying mechanism, which includes a silo, a conveyor belt assembly, and a blocking assembly; the conveyor belt assembly includes a driving unit, a driving wheel, a driven wheel, and a conveyor belt; the driving unit is connected to the driving wheel to drive the driving wheel to rotate; the driven wheel and the driving wheel are spaced apart from each other; the conveyor belt surrounds the driving wheel and the driven wheel, and is located below the discharge port of the silo to receive the particulate material sent out from the discharge port of the silo; the outer surface of the conveyor belt is provided with a receiving hole for accommodating particulate material; the blocking assembly is located at the rear side of the discharge port of the silo to block the material on the conveyor belt located outside the receiving hole; the blocking assembly includes a mounting block and a brush; the mounting block is connected to the discharge port of the silo; the brush is arranged at the bottom of the mounting block and is located above the conveyor belt to block the material on the conveyor belt located above the receiving hole. The granular material conveying mechanism is provided with the conveyor belt assembly, and the conveyor belt is provided with the receiving hole, so that the granular material delivered from the silo can be received and received through the receiving hole. Under the drive of the drive unit, the granular material can be conveyed to the rear side. The belt structure is used to convey the granular material. The overall structure is simple and the volume is small, which can be installed and used in relatively narrow installation areas. The blocking assembly is also provided to block the granular material outside the receiving hole, thereby better ensuring the quantitative conveyance of the granular material by the granular material conveying mechanism.

[0040] Please refer to Figures 1 to 7 This embodiment provides a granular material conveying mechanism 100, which is used to provide a new granular material conveying structure to better adapt to installation in a relatively narrow installation area and more easily realize long-distance conveyance of granular materials. Specifically, the granular material is a granular material for cigarettes.

[0041] The particulate material conveying mechanism 100 includes a silo 10, a conveyor belt assembly 20, and a blocking assembly 30. The silo 10 is used to accommodate particulate materials, the conveyor belt assembly 20 is used to gradually convey the particulate materials in the silo 10 outward, and the blocking assembly 30 is used to block excess particulate materials on the conveyor belt assembly 20.

[0042] The conveyor belt assembly 20 includes a drive unit, a driving wheel 21, a driven wheel 22, and a conveyor belt 23. The drive unit is connected to the driving wheel to drive the driving wheel 21 to rotate. Specifically, the drive unit can be a motor. The driven wheel 22 and the driving wheel 21 are spaced apart from each other. The conveyor belt 23 surrounds the driving wheel 21 and the driven wheel 22. The conveyor belt 23 is located below the discharge port 11 of the silo 10 to receive the granular material sent out from the discharge port 11. When conveying the granular material, the drive unit drives the driving wheel 21 to rotate, and the driving wheel 21 drives the conveyor belt 23 to operate, so that the conveyor belt 23 transports the received granular material to the rear side in a linear movement manner.

[0043] The outer surface of the conveyor belt 23 is provided with a receiving hole 231 for accommodating granular material. Granular material falling from the discharge port 11 can flow into the receiving hole 231 for accommodation. The blocking assembly 30 is located behind the discharge port 11 and is used to block material on the conveyor belt 23 that is outside the receiving hole 231. The location of the blocking assembly 30 behind the discharge port 11 is based on the conveying direction of the conveyor belt 23. When the conveyor belt 23 is in operation, it first passes through the discharge port 11 and then passes through the blocking assembly 30.

[0044] It is understood that when particulate material falls from the discharge port 11 onto the conveyor belt 23, some may fall into the receiving hole 231, while another portion may fall onto the outer surface of the conveyor belt 23, located outside the receiving hole 231. This will cause the amount of particulate material transported by the conveyor belt 23 to vary each time, making it impossible to achieve quantitative transport of particulate material, thereby affecting the stability of quantitative transport of particulate material. However, through the provision of the blocking assembly 30, after the conveyor belt 23 receives particulate material from the discharge port 11, the blocking assembly 30 can block the particulate material located outside the receiving hole 231, thereby ensuring that the particulate material transported to the rear side is only located in the receiving hole 231, thereby achieving quantitative transport of particulate material and better ensuring the stability of quantitative transport of particulate material. The size of the receiving hole 231 can be selected according to the amount of material required to be transported each time. For example, the size of the receiving hole 231 can be adapted to one granular material, so that each of the receiving holes 231 can only accommodate one granular material at a time; or, the size of the receiving hole 231 can be adapted to multiple granular materials, so that each of the receiving holes 231 can simultaneously accommodate multiple granular materials at a time. The size of the receiving hole 231 can be selected according to actual needs.

[0045] The blocking assembly 30 includes a mounting block 31 and a brush 32. The mounting block 31 is connected to the discharge port 11. By directly connecting the mounting block 31 to the discharge port 11, other mounting structures can be eliminated, making the overall structure more compact and simple. The brush 32 is arranged at the bottom of the mounting block 31 and is located above the conveyor belt 23 to block the material located above the receiving hole 231 on the conveyor belt 23. It is understandable that the particulate material for cigarettes is very easy to be damaged. By blocking and scraping the particulate material for cigarettes with the brush 32, it is possible to better avoid the damage of the particulate material and better ensure the reliability of transportation.

[0046] It should be noted that the equipment for conveying granular materials in the prior art is usually a disc-shaped structure, and the distance that can be conveyed is related to the diameter of the disc. If you want to convey granular materials over long distances, the overall structure needs to be designed as a disc-shaped structure with a longer diameter, which is not conducive to installation and use. In addition, the existing disc-shaped structure is limited in installation in a relatively narrow installation area and has limitations. At the same time, the existing conveying equipment uses a disc-shaped structure to dock and convey granular materials in a rotating form, which requires high installation accuracy. When there are errors in the installation, the granular materials are easily squeezed between the components during the material receiving process, causing damage to the granular materials, and the transportation of the granular materials is not stable enough.

[0047] The conveying distance of the granular material conveying mechanism 100 provided in this embodiment is related to the spacing between the driving wheel 21 and the driven wheel 22, as well as the length of the conveyor belt 23. Long-distance conveyance of granular material can be achieved by simply adjusting the spacing between the two wheels and the length of the conveyor belt 23, making installation more convenient. Furthermore, the use of a belt structure to convey granular material has a simple overall structure and a small size, allowing installation and use in relatively narrow installation areas. Furthermore, the conveyor belt 23 receives and conveys granular material in a linear manner, thereby better preventing damage to the granular material and ensuring more stable material transportation.

[0048] Preferably, in one embodiment, the receiving holes 231 are arranged in multiple groups at intervals along the length of the conveyor belt 23, and the spacing between two adjacent groups of receiving holes 231 is equal. By providing multiple groups of receiving holes 231, the particulate material can be continuously and uninterruptedly conveyed, thereby improving conveying efficiency.

[0049] Preferably, in one embodiment, each group of the accommodating holes 231 includes two accommodating holes 231, and the two accommodating holes 231 in each group of the accommodating holes 231 are spaced apart from each other along the length of the conveyor belt 23. That is, in this embodiment, when the conveyor belt 23 is conveying granular material, it can convey the granular material in two accommodating holes 231 to the rear side in groups, and the docking equipment on the rear side can receive the granular material from the two accommodating holes 231 at a time. Specifically, in one embodiment, each accommodating hole 231 is compatible with one granular material. That is, the accommodating hole 231 can only accommodate one granular material at a time, and when the conveyor belt 23 is conveying granular material, it conveys the granular material to the rear side equipment in units of two granular materials.

[0050] Preferably, in one embodiment, the receiving hole 231 is circular. That is, the receiving hole 231 is a circular structure as a whole, and the sidewall of the receiving hole 231 is a curved surface structure, so as to better adapt to the granular material and avoid squeezing the granular material and causing damage.

[0051] Preferably, in one embodiment, the blocking assembly 30 further includes a blocking block 33, and the blocking block 33 includes a mounting portion 331 and a blocking portion 332 connected to the mounting portion 331. The mounting portion 331 is connected to the discharge port 11. By directly connecting the mounting portion 331 to the discharge port 11, other mounting structures can be eliminated, making the overall structure more compact and simple. The conveyor belt 32 passes through the blocking portion 332, and the blocking portion 332 is provided with an avoidance groove 3321. The avoidance groove 3321 is provided corresponding to the accommodating hole 231, and the avoidance groove 3321 is provided along the length direction of the blocking portion 332 and penetrates the blocking portion 332. When the conveyor belt 23 is in operation, the particulate material in the receiving hole 231 on the conveyor belt 23 can flow smoothly through the blocking portion 332 via the avoidance groove 3321, while the particulate material at other locations on the outer surface of the conveyor belt 23 is blocked by the sidewalls on both sides of the avoidance groove 3321, thereby ensuring that the particulate material transported backward is only located in the receiving hole 231, achieving quantitative material transportation. In other words, in this embodiment, the brush 32 can block the particulate material in the height direction, while the blocking portion 332 can block the particulate material in the width direction of the conveyor belt 23, thereby better ensuring the quantitative transportation of the particulate material by the conveyor belt 23. Furthermore, the provision of the avoidance groove 3321 can also better prevent the blocking portion 332 from squeezing the particulate material in the receiving hole 231.

[0052] Preferably, in one embodiment, the blocking portion 332 is located at the rear side of the brush 32. That is, when the conveyor belt 23 is running, the material first passes through the brush 32 and then passes through the blocking portion 332.

[0053] Preferably, in one embodiment, the conveyor belt assembly 20 further includes a negative pressure generating unit, which is in communication with the receiving hole 231 and is configured to provide negative pressure within the receiving hole 231. By providing negative pressure within the receiving hole 231, the negative pressure generating unit can stably adsorb the particulate material within the receiving hole 231 and allow it to travel with the conveyor belt 23. Specifically, when the conveyor belt assembly 20 is configured, grooves can be provided on the side panels of the conveyor belt 23. The grooves can be in communication with the receiving hole 231, and the negative pressure generating unit can be in communication with the grooves to provide negative pressure within the receiving hole 231. The grooves can be positioned only between the discharge port 11 and the discharge position of the conveyor belt 23. When the receiving hole 231 reaches the discharge position, the negative pressure is discontinued. This ensures more stable transport of particulate material by the conveyor belt 23 and facilitates access to the particulate material by subsequent equipment.

[0054] Preferably, in one embodiment, a recovery component 40 is provided below the blocking component 30 so as to recover the particulate material that is blocked and falls.

[0055] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
