Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing, in particular to a tobacco feeding mechanism. Background Art

[0002] Cigarettes are made from tobacco leaves through multiple processes. For example: after the tobacco is harvested, it will be baked in a tobacco factory first. After the tobacco baking is completed, the tobacco is packed and transported to a cigarette factory, and then the next step of processing is continued. The tobacco leaves are in sheet form, so before being sent to the cigarette factory, the tobacco needs to be packed first to facilitate transportation.

[0003] The common method of packing tobacco (or waste) is that workers pour the tobacco leaves into a compressor (manual feeding), and then the compressor compresses the tobacco leaves into blocks. This manual feeding has low efficiency and affects the packing speed.

[0004] For example, a waste compression packing machine disclosed in Chinese Patent Application No.: CN202222761728.9. Specifically, it discloses that "tobacco waste is loaded in a waste box and transported through a conveying device. A compression device is arranged at the end of the conveying device. The compression device includes a pressing box with a cavity inside. When the waste box loaded with tobacco waste is successively transported to the end of the conveying device, the staff pours the tobacco waste in the waste box into the cavity of the pressing box. After a certain amount of tobacco waste is accommodated in the cavity, the compression device compresses the tobacco waste in the cavity, squeezes the fluffy tobacco waste into a dense geometric body with a certain volume, and then takes out the dense geometric body of tobacco waste from the cavity for transfer". It can be seen that this kind of packing equipment is to manually pour tobacco into the cavity of the pressing box for compression packing (manual feeding), which has the problem of low feeding efficiency and affecting the packing speed.

[0032] Please refer to Figures 1 to 6 as shown, which shows the specific structure of the preferred embodiment of the present invention, and is a tobacco feeding mechanism.

[0033] Among them, the flipping device 20 can flip the first bin 16 on the first conveying device 10, and the first bin 16 automatically falls into the second bin 410. After the tobacco in the second bin 410 is compressed, the bottom plate 46 is withdrawn from the second bin 410, then the box door 413 on the box body 416 is opened, and then the second bin 410 is reset, realizing the automatic feeding of tobacco, eliminating the need for manual feeding, and helping to improve the packing efficiency.

[0034] The present application provides a tobacco feeding mechanism, including a first conveying device 10; a turning device 20 is arranged on the first conveying device 10; the turning device 20 can turn the first bin 16 on the first conveying device 10; a second conveying device 30 is arranged on the lower side of the first conveying device 10; a third conveying device 40 is arranged on the second conveying device 30; a second bin 410 is arranged on the third conveying device 40, and the bottom plate 46 of the third conveying device 40 can be withdrawn from the second bin 410; the second bin 410 includes a box body 416 and a box door 413 that can be opened and closed on the box body 416. The first bin 16 in this embodiment is used to load tobacco, and of course, other materials can also be loaded, such as tobacco waste, leaves, etc. The first bin 16 is placed on the first conveying device 10, and the first conveying device 10 conveys the first bin 16 to the turning device 20. The second conveying device 30 enables the second bin 410 and the third conveying device 40 to move together. When the second bin 410 moves below the turning device 20, the turning device 20 turns one or more first bins 16 and pours them into the second bin 410. Subsequently, the second bin 410 moves to the position of the compressor, and the pressing plate of the compressor presses down into the second bin 410 from top to bottom, and the tobacco is compressed into blocks. After the tobacco is compressed, the bottom plate 46 is withdrawn from the second bin 410, and then the box door 413 of the box body 416 is opened. The second conveying device 30 conveys the second bin 410 and the third conveying device 40 below the turning device 20 to continue receiving tobacco. It can be seen that the efficiency of this automatic tobacco feeding is high, and the degree of automation is high, which helps to improve the feeding efficiency.

[0035] Preferably, the first conveying device 10 includes a first conveyor belt, a first rack track 11 arranged on the upper side of the first conveyor belt, a gearbox 12 arranged on the first rack track 11, and the output shaft of the first motor 15 is connected to one of the gearboxes 12; a transmission shaft 13 is arranged between the two gearboxes 12. The first motor 15 is preferably a servo motor. The first conveyor belt can be a roller conveyor belt. At this time, the first conveyor belt has a certain inclination angle, and the first bin 16 will move to the turning device 20 under the action of gravity. Of course, the first conveyor belt can also be other conveyor belts driven by a motor. After the turning device 20 pours the tobacco in the first bin 16 into the second bin 410, the turning device 20 clamps the first bin 16, and the power of the first motor 15 is transmitted to the gearbox 12. The gearbox 12 drives the turning device 20 to move on the first rack track 11, so that the empty first bin 16 will move to the initial position, facilitating the removal of the empty first bin 16. The transmission shaft 13 is arranged between the gearboxes 12, so that the power of the first motor 15 can be evenly transmitted to the two groups of first rack tracks 11, and the movement is more stable.

[0036] Preferably, the tipping device 20 includes a first mounting bracket 21, a first sliding module 22 provided on the first mounting bracket 21, a first rotary cylinder 23 provided on the first sliding module 22, and a first driving cylinder 25 connected to the first rotary cylinder 23; the first driving cylinder 25 drives the first rotary cylinder 23 to slide on the first sliding module 22, and the first rotary cylinder 23 clamps and tips the first bin 16, and can pour the material into the second bin 410. The tipping device 20 is arranged on the first rack track 11, and each first rack track 11 corresponds to one first rack track 11. The first mounting bracket 21 is arranged in the gearbox 12, and the first motor 15 drives the tipping device 20 to move back and forth on the first rack track 11. The first rotary cylinder 23 is arranged on the third mounting bracket 24, and the third mounting bracket 24 is arranged on the first sliding module 22. When the first bin 16 moves to the tipping device 20, the first driving cylinder 25 drives the third mounting bracket 24 to move towards the first bin 16, and the clamping blocks at the output end of the first rotary cylinder 23 are embedded into the positioning grooves 17 of the first bin 16, and the clamping blocks on both sides clamp the first bin 16. Subsequently, the first rotary cylinder 23 operates, and then the material in the first bin 16 is poured into the second bin 410. This mechanism eliminates the need for manual feeding and has higher work efficiency.

[0037] Preferably, the first conveying device 10 further includes a hopper 14, which is located below the first bin 16, and the first bin 16, the hopper 14, and the second bin 410 can be aligned with each other. When the first bin 16 tips the tobacco, the tobacco passes through the hopper 14 and then falls into the second bin 410, and this design improves the accuracy during tipping.

[0038] Preferably, the second conveying device 30 includes a first track 31, and a plurality of first rollers 32 are arranged on the first track 31; the third conveying device 40 moves on the first rollers 32. The third conveying device 40 moves on the first rollers 32, and its frictional resistance is very small. Among them, the power source of the second conveying device 30 comes from the second conveyor belt 41. In this embodiment, the second conveyor belt 41 drives the second bin 410 to move on the first rollers 32. This design simplifies the structure and reduces the equipment cost.

[0039] Preferably, the third conveying device 40 includes a second conveyor belt 41 and a second driving cylinder 45; a second mounting bracket 43 is connected between the second bin 410 and the second conveyor belt 41; the second driving cylinder 45 is arranged in the second bin 410, and the output end of the second driving cylinder 45 is connected to the bottom plate 46; the second driving cylinder 45 drives the bottom plate 46 to be withdrawn from the second bin 410. The second conveyor belt 41 is driven by a second motor, and the second motor is preferably a servo motor. The second mounting bracket 43 connects the second conveyor belt 41 and the second bin 410 together, and the power of the second conveyor belt 41 can be transmitted to the second bin 410. Therefore, the second conveyor belt 41 drives the second bin 410 to move back and forth on the first roller 32 of the first track 31, so that the second bin 410 can move back and forth between the turning device 20 and the compressor. During compression, the box door 413 is closed. After compression is completed, the second driving cylinder 45 drives the bottom plate 46 to be withdrawn from the bottom of the second bin 410, and then the third driving cylinder 411 drives the box door 413 to open. Subsequently, the second conveyor belt 41 drives the second bin 410 to reset, the box door 413 closes, and the second bin 410 continues to load tobacco.

[0040] Preferably, a second track 42 is arranged beside the second conveyor belt 41; a second roller 44 is arranged on the second mounting bracket 43, and the second roller 44 rolls on the second track 42. A third track 47 is arranged on the second bin 410, and a third roller 48 is arranged on the bottom plate 46. The third roller 48 moves on the third track 47 and presses on the third track 47. When the second conveyor belt 41 drives the second bin 410 to move, the second roller 44 rolls on the second track 42, and the second roller 44 can play a supporting role; the third roller 48 moves on the third track 47, the third roller 48 presses on the third track 47, and the third roller 48 plays a limiting role. In this way, the movement track of the second bin 410 can be well restricted, preventing the second bin 410 from deviating, and the movement accuracy is high.

[0041] Preferably, a third driving cylinder 411 is provided on the box body 416, and the output end of the third driving cylinder 411 is connected to the box door 413. The third driving cylinder 411 drives the box door 413 to open or close. A fourth driving cylinder 412 is provided on one of the box doors 413, and the output end of the fourth driving cylinder 412 is connected to the bolt 414. The fourth driving cylinder 412 drives the bolt 414 to insert into the lock hole 415 on the other box door 413. When the tobacco is compressed, the third driving cylinder 411 drives the box door 413 to close, and at the same time, the fourth driving cylinder 412 drives the bolt 414 to insert into the lock hole 415 on the other box door 413. In this way, the second material box 410 is closed, and the compression package of the compressor can be pressed into the second material box 410 from the top of the second material box 410 to compress the tobacco leaves. After the compression is completed, the bottom plate 46 is withdrawn from the second material box 410, and the bolt 414 and the box door 413 are opened. The efficiency of compressing by using its own structure is very high.

[0042] In summary, the design focus of the present invention is that the flipping device 20 can flip the first material box 16 on the first conveying device 10 and pour it into the second material box 410. Subsequently, the second conveying device 30 conveys the third conveying device 40 and the second material box 410 to the compression area, and the compressor compresses the tobacco in the second material box 410. After the tobacco is compressed, the bottom plate 46 is withdrawn from the second material box 410, and then the box door 413 on the box body 416 is opened, and then the second material box 410 is reset. It can be seen that this is a design of automatic feeding, with a high degree of automation and is helpful to improve the packing efficiency.
