Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production equipment, in particular to a metering tube cleaning device and a feeding system. Background Art

[0002] Tobacco production requires a stable feeding system to ensure a steady supply of tobacco material, known as a quantitative feeding process. This system includes a flow-buffered feeder, a photoelectric metering tube, and an electronic belt scale mounted at the rear end of the feeder. The feeder comprises a feeding hopper, a bottom belt, and an elevator. During this process, a storage cabinet feeds tobacco leaves of varying grades from the previous process through a vibrating screen into one end of the feeding hopper. The bottom belt transports the leaves to the elevator at the other end of the feeding hopper. The elevator lifts the leaves to the top of the metering tube and unloads them into it. A photoelectric tube is located inside the metering tube. The leaves pass through the metering tube and then fall onto the electronic belt scale, where they are weighed and transferred to the next process.

[0003] However, due to the light weight of tobacco leaves, some of them are easily adsorbed on the photoelectric tube, resulting in incorrect recognition by the photoelectric tube. The tube mistakenly thinks that the material in the metering tube is full and stops the lifting belt, causing the electronic scale to break. Manual cleaning of the photoelectric tube is required, affecting the production rhythm and efficiency. Utility Model Content

[0033] The storage cabinet feeds tobacco leaves of different grades from the previous process through a vibrating screen and into one end of the feed hopper. A bottom belt conveys the leaves to an elevator belt at the other end of the feed hopper. The elevator belt lifts the leaves to the top of a metering tube and unloads them into it. A photoelectric tube is located inside the metering tube. After passing through the tube, the leaves fall onto an electronic belt scale, which weighs them and transfers them to the next process. However, due to the light weight of the tobacco leaves, some of them easily stick to the photoelectric tube, causing the tube to misidentify the leaves and stop the elevator belt, mistakenly thinking that the metering tube is full. This causes the electronic scale to break the material and requires manual cleaning of the photoelectric tube, affecting production rhythm and efficiency.

[0034] In order to solve the above problems, this embodiment provides a feeding system, see Figure 1 and Figure 2, comprising a metering tube 1, a photoelectric tube 2 and a metering tube cleaning device, wherein the metering tube cleaning device and the photoelectric tube 2 are both placed inside the metering tube 1. The metering tube cleaning device comprises a blow pipe 10, a gas assembly 20 and a drive assembly 30. The blow pipe 10 is arranged inside the metering tube 1, and both the metering tube 1 and the blow pipe 10 extend along a first direction. The blow pipe 10 is provided with a plurality of blow holes 11 spaced apart along the first direction to ensure that different heights of the inner wall of the metering tube 1 can be evenly cleaned by compressed air. Specifically, the metering tube 1 is configured as a prismatic tube and extends along a vertical direction, and the blow pipe 10 is configured as a square tube and fits the inner wall of the metering tube 1. The side wall of the square tube is provided with a plurality of circular holes, which serve as the blow holes 11. To improve the uniformity of the blow, the blow holes 11 are evenly spaced apart. In other embodiments, the blow pipe 10 can be configured as a circular tube, etc.

[0035] Furthermore, the gas component 20 includes an air pipe 21 and a gas compressor 22. The air pipe 21 connects the gas compressor 22 and the blowpipe 10. The gas compressor 22 provides gas to the blowpipe 10 through the air pipe 21 and sprays gas from the blowpipe orifice 11. The drive component 30 can drive the blowpipe 10 to move in the metering tube 1. Specifically, the air pipe 21 can be set as a silicone hose to avoid affecting the movement of the blowpipe 10. Furthermore, the gas component 20 also includes a control valve 23. The control valve 23 is provided at one end of the air pipe 21 close to the gas compressor 22 to open or close the air pipe 21. The control valve 23 can prevent the compressed air flow from being too large and blowing dust and tobacco out of the mounting hole of the photoelectric tube 2. In this embodiment, in order to save energy, a solenoid valve for time control can be added to the control valve 23 to allow the compressed air to be periodically intermittently turned on and off. By using the blowing pipe 10 to blow the tobacco leaves in the metering tube 1 and the blowing pipe 10 can move inside the metering tube 1, the blowing area of ​​the metering tube 1 is increased, the tobacco leaves are prevented from adsorbing the photoelectric tube 2, and the photoelectric tube 2 avoids recognition errors, thereby improving the production rhythm and efficiency.

[0036] Furthermore, the drive assembly 30 includes a slide rail 31 disposed within the metering tube 1 along a second direction perpendicular to the first direction. The blowpipe 10 is provided with a slider 12 slidably mounted on the slide rail 31. In this embodiment, the first direction is the Z direction, and the second, opposite direction is the Y direction. In other embodiments, the blowpipe 10 can also be moved along the second direction via the cooperation of the slide rails or the use of a screw nut.

[0037] Furthermore, the drive assembly 30 includes a motor 32, a gear 33, and a rack 34. The rack 34 is fixedly connected to the blowpipe 10 and meshes with the gear 33. The motor 32 can drive the gear 33 to rotate, thereby driving the rack 34 to move in the second direction. In this embodiment, the rack 34 is connected to the blowpipe 10 via a fastener. The fastener can be a bolt. In other embodiments, the rack 34 can also be glued or clamped to the blowpipe 10.

[0038] Furthermore, the motor 32 is arranged at the top of the metering tube 1. Specifically, the drive assembly 30 also includes a fixed frame 39, which is configured as an L-shaped plate, and the motor 32 is fixed to the L-shaped plate by bolts. The drive assembly 30 also includes a first transmission shaft 35, a first bevel gear, a second transmission shaft 36, and a second bevel gear. One end of the first transmission shaft 35 is connected to the motor 32 and the other end is connected to the first bevel gear. One end of the second transmission shaft 36 is connected to the gear 33 and the other end is connected to the second bevel gear. The first bevel gear and the second bevel gear are meshed. The motor 32 drives the gear 33 to rotate through the first transmission shaft 35 and the second transmission shaft 36. Specifically, there are two blowing tubes 10, and two gears 33 are correspondingly provided. The two gears 33 rotate in opposite directions. The motor 32 drives the two blowing tubes 10 to move in opposite directions. The blown air flows intersect with each other to form shear, so that the air flow inside the metering tube 1 flows in multiple directions, ensuring the blowing effect. Specifically, the drive assembly 30 also includes a coupling 37, which connects the first transmission shaft 35 to the motor 32 and the first bevel gear; and the second transmission shaft 36 to the gear 33 and the second bevel gear. Specifically, the drive assembly 30 also includes a bearing seat 38, which is disposed on the top wall of the metering tube 1. The second transmission shaft 36 penetrates the bearing seat 38 and rotates in engagement with the bearing seat 38, thereby increasing the stability of the second transmission shaft 36.

A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
