[0049] The working principle is as follows: When the device for the tobacco leaf threshing process with the intelligent manufacturing automatic metering and weighing function of the Great Chungkiu Special Line with the above design structure is in use, the operator only needs to manually or by means of corresponding handling equipment carry it to the designated working position for use.

[0050] During use, an external control device controls the motor to operate the conveyor belt on the conveying and weighing device (1). The motor (56) of the vibrating sieve assembly drives the connecting rod (53) to rotate. As the connecting rod (53) rotates, it drives the rotating disk (54) and the first sprocket (55) to rotate. Since bumps are installed on the outer surface of the rotating disk (54), when the rotating disk (54) rotates, the convex rod (514) will drive the sieve plate (51) to move under the action of the bumps. Under the action of the limit pin (511) and the telescopic spring (512), the sieve plate (51) vibrates up and down. After the cut tobacco (9) enters the feed hopper (4), the sieve plate (51) screens out the debris (10) in the cut tobacco (9). The screened debris (10) will fall onto the chip discharge plate (52) and then into the material collection box (72). The cut tobacco (9) after the debris (10) is screened out falls onto the inclined plate (61) along with the vibration of the sieve plate (51). At this time, the baffle plate (622) blocks the cut tobacco (9) on the inclined plate (61). When the first sprocket (55) rotates, the second sprocket (632) drives the fixed rod (63) to rotate under the transmission of the transmission chain (65). As the fixed rod (63) rotates, it drives the driving gear (631) to rotate. When the driving gear (631) meshes with the driven gear (621), it drives the rotating rod (62) to rotate, so that a gap is generated between the baffle plate (622) and the inclined plate (61), and the cut tobacco (9) will flow through the gap into the blanking cylinder (3). When the driven gear (621) and the driving gear (631) are disengaged, under the action of the torsion spring (64), the rotating rod (62) drives the baffle plate (622) to block the cut tobacco (9) on the inclined plate (61) again. Since the blanking cylinder (3) is designed with transparency, the cut tobacco (9) can be observed when it falls in the blanking cylinder (3). At the same time, the inductive phototube (31) can adjust the speed of the conveyor belt according to the level of the cut tobacco (9). After the cut tobacco (9) falls onto the conveyor belt, the conveyor belt will bend under the weight of the cut tobacco (9). When bending, it will cause the sensor to generate an electrical signal. Then the sensor converts these electrical signals into digital signals and processes them through an external control device to calculate the weight of the cut tobacco (9) falling each time. The cut tobacco (9) is conveyed along with the conveyor belt through the protective cover (2). At this time, the moisture content detector (21) in the protective cover (2) detects the moisture content in the cut tobacco (9). When the cut tobacco (9) moves into the fixed cover (81), the vibrator (82) drives the first movable rod (83) to vibrate back and forth under the limitation of the limit rod (86). While the first movable rod (83) vibrates back and forth, it drives the fixed rack (87) to vibrate synchronously. Under the transmission of the rotating gear (89), the second movable rod (85) also vibrates, causing the two first movable rods (83) to form a cross vibration. Then, the cut tobacco (9) on the conveyor belt is leveled by the rivets (84), and the leveled cut tobacco (9) falls to the next process.

[0051] The beneficial effects of the present invention compared with the prior art are as follows:

[0052] 1. In the present invention, due to the provision of a vibrating sieve assembly, it can automatically screen out the debris in the cut tobacco before the conveying and weighing equipment weighs the cut tobacco, reducing the content of debris in the cut tobacco, thereby improving the quality of the cigarette after rolling;

[0053] 2. In the present invention, due to the provision of a baffle assembly, it can control the amount of cut tobacco falling each time, making the amount of cut tobacco falling more uniform and avoiding the situation of blockage at the feed inlet caused by excessive single - time falling of cut tobacco;

[0054] 3. In the present invention, due to the adoption of a flattening assembly, it can realize the function of automatic flattening during the conveying process of the conveying equipment, avoiding the cut tobacco being in a tangled state in subsequent operations, and at the same time adopting cross - vibration to improve the flattening efficiency and looseness of the cut tobacco;

[0055] 4. In the present invention, due to the provision of a flattening assembly, it can ensure that the cut tobacco remains in a uniform and flat state, avoiding problems such as overlapping, knotting or damage of the cut tobacco; at the same time, the automated operation of the cut tobacco flattening assembly reduces the labor input, improves the automation level of the production line, and thus improves the production efficiency and guarantees the product quality.

[0056] 5. The blanking cylinder of the present invention adopts a transparent design. On the one hand, it is convenient to observe the inside of the blanking cylinder. When the cut tobacco is blocked inside the blanking cylinder, it is convenient to deal with it in time; on the other hand, the feeding rate of the feeding equipment can be adjusted by observing the height of the blanking, which can make the weighing of the conveying equipment more accurate and improve the measurement accuracy;

[0057] 6. The present invention adopts an inductive phototube, and combined with the transparent design of the blanking cylinder, the cut tobacco can be observed when the cut tobacco falls inside the blanking cylinder. At the same time, the inductive phototube can feedback the level of the cut tobacco in the blanking cylinder to the external control equipment, and the external control equipment then adjusts the conveyor belt speed of the conveying equipment;

[0058] 7. The conveying and weighing equipment in the present invention is fast and efficient, can achieve high - precision weight measurement, ensure data accuracy, and can measure the weight immediately when the cut tobacco passes through, reducing manual intervention, greatly improving work efficiency, and contributing to quality management and production process control;

[0059] 8. The present invention is provided with a moisture content detector, which can ensure the production quality by detecting the moisture content of the cut tobacco and prevent production problems caused by too high or too low moisture content; at the same time, it can record the data of each measurement, send the data to the external control equipment for storage, provide a data traceability function, facilitate understanding the production situation of each processing link, and contribute to quality management and production process monitoring.

[0086] In summary, the more specific embodiments of the present invention are as follows:

[0087] Embodiment 1

[0089] A blanking cylinder 3, which is arranged at the feeding end of the conveyor weighing device 1;

[0090] A feeding hopper 4, which is connected and arranged at the top of the blanking cylinder 3, and a through opening is formed through the lower part of one side of the feeding hopper 4;

[0091] A vibrating sieve assembly 5, which is arranged above the inside of the feeding hopper 4;

[0092] The partition component 6 is arranged below the vibrating screen component 5 and works in cooperation with the vibrating screen component 5; among them,

[0093] Both the conveying and weighing device 1 and the vibrating screen component 5 are connected to an external control device.

[0094] In the present invention, the conveying and weighing device 1 is a device for measuring and recording the weight of cut tobacco. The conveying and weighing device 1 includes a sensor, a data acquisition system, a display / recording device, and a conveying device, which can quickly and accurately measure the weight of the cut tobacco and transmit the data to the external control device; when the cut tobacco 9 falls onto the conveyor belt of the conveying and weighing device 1, the conveyor belt will be bent under the action of the weight of the cut tobacco 9. When bent, it will cause the sensor to generate an electrical signal, and then the sensor converts these electrical signals into digital signals, and then processes them through the external control device to calculate the weight of the cut tobacco 9 falling once. At the same time, the external control device can control the transmission speed of the conveyor belt of the conveying and weighing device 1.

[0095] Furthermore, as Figure 2 and Figure 3 shown, it further includes: a moisture content detector 21, which is arranged on the inner wall of the protective cover 2;

[0097] Among them, both the moisture content detector 21 and the induction phototube 31 are connected to the external control device.

[0098] In the present invention, the moisture content detector 21 inside the protective cover 2 detects the moisture content of the cut tobacco 9; the induction phototube 31 can feedback the level of the cut tobacco 9 in the blanking cylinder 3 to the external control device, and the external control device then adjusts the conveyor belt speed of the conveying and weighing device 1.

[0099] In the present invention, the external control device is a programmable logic controller or a PLC or a PC.

[0100] Furthermore, as Figures 1 to 3 shown, the blanking cylinder 3 is designed to be transparent, which is convenient for observing the situation of the cut tobacco 9 falling in the blanking cylinder 3. Among them, a leak-proof plate 32 is also provided at the connection between the blanking cylinder 3 and the feeding end of the conveying and weighing device 1.

[0101] Furthermore, as Figures 5 to 9 shown, the vibrating screen component 5 includes:

[0102] A sieve plate 51, both sides of the sieve plate 51 are slidably connected in the limiting grooves of the feeding hopper 4;

[0103] The chip discharging plate 52, one end of the chip discharging plate 52 is inclined and connected below the sieve plate 51, and the other end of the chip discharging plate 52 passes through the through port of the feeding hopper 4 and extends to the outside of the feeding hopper 4;

[0120] Specifically, Figure 8 and Figure 9 As shown in the figure, a protective cover 66 is also provided outside the second sprocket 632 end of the fixed rod 63 and the driven gear 621 end of the rotating rod 62. The protective cover 66 is connected to the outside of the feed hopper 4, and an opening for the transmission chain 65 to work is provided through one side of the protective cover 66;

[0121] One end of the torsion spring 64 is connected to the inner side wall of the protective cover 66, and the other end of the torsion spring 64 is connected to the fixed rod 63;

[0122] The driven gear 621 is a semi-gear or a full gear; the driving gear 631 is a full gear or a semi-gear, and the driving gear 631 is meshed with the driven gear 621; wherein, the driven gear 621 and the driving gear 631 are different gears.

[0123] In the present invention, one end of the fixed rod 63 is also rotatably connected to the inner wall of the protective cover 66; if the driven gear 621 is a semi-gear, then the driving gear 631 is a full gear, and if the driven gear 621 is a full gear, then the driving gear 631 is a semi-gear.

[0124] In the present invention, the baffle 622 blocks the cut tobacco 9 on the inclined plate 61. When the first toothed sprocket wheel 55 rotates, the second toothed sprocket wheel 632 drives the fixed rod 63 to rotate under the drive of the transmission chain 65. As the fixed rod 63 rotates, it drives the drive gear 631 to rotate. When the drive gear 631 meshes with the driven gear 621, it drives the rotating rod 62 to rotate, thereby creating a gap between the baffle 622 and the inclined plate 61, and the cut tobacco 9 flows into the blanking cylinder 3 through the gap. When the driven gear 621 loses engagement with the drive gear 631, under the action of the torsion spring 64, the rotating rod 62 drives the baffle 622 to block the cut tobacco 9 on the inclined plate 61 again.

[0125] When the tobacco processing device with automatic metering and weighing function of the above structure is in use, the external control device controls the motor to make the conveyor belt on the conveyor weighing device 1 work. The vibrating screen assembly motor 56 drives the connecting rod 53 to rotate. As the connecting rod 53 rotates, it drives the rotating disk 54 and the first sprocket 55 to rotate. Since bumps are installed on the outer surface of the rotating disk 54, when the rotating disk 54 rotates, the convex rod 514 will drive the sieve plate 51 to move under the action of the bumps. Under the action of the limit pin 511 and the telescopic spring 512, the sieve plate 51 vibrates up and down. After the cut tobacco 9 enters the feed hopper 4, the sieve plate 51 will screen out the debris 10 in the cut tobacco 9. The screened debris 10 will fall onto the chip discharge plate 52. The cut tobacco 9 after the debris 10 is screened out falls onto the inclined plate 61 along with the vibration of the sieve plate 51. At this time, the baffle 622 will block the cut tobacco 9 on the inclined plate 61. When the first sprocket 55 rotates, it drives the second sprocket 632 to drive the fixed rod 63 to rotate through the transmission of the transmission chain 65. As the fixed rod 63 rotates, it drives the driving gear 631 to rotate. When the driving gear 631 meshes with the driven gear 621, it drives the rotating rod 62 to rotate, so that a gap is generated between the baffle 622 and the inclined plate 61, and the cut tobacco 9 will flow into the blanking cylinder 3 through the gap. When the driven gear 621 and the driving gear 631 lose meshing, under the action of the torsion spring 64, the rotating rod 62 drives the baffle 622 to block the cut tobacco 9 on the inclined plate 61 again. Since the blanking cylinder 3 is made of transparent design, the cut tobacco 9 can be observed when it falls in the blanking cylinder 3. At the same time, the inductive phototube 31 can adjust the speed of the conveyor belt according to the level of the cut tobacco 9. After the cut tobacco 9 falls onto the conveyor belt, the conveyor belt will be bent under the action of the weight of the cut tobacco 9. When bent, it will cause the sensor to generate an electrical signal, and then the sensor converts these electrical signals into digital signals, and then processes them through the external control device to calculate the weight of the cut tobacco 9 falling each time. The cut tobacco 9 is conveyed along with the conveyor belt through the protective cover 2. At this time, the moisture content detector 21 in the protective cover 2 will detect the moisture content in the cut tobacco 9, so as to ensure the production quality by detecting the moisture content of the cut tobacco and prevent production problems caused by too high or too low moisture content; at the same time, it can record the data measured each time, send the data to the external control device for storage, provide the data traceability function, facilitate the understanding of the production situation of each processing link, and contribute to quality management and production process monitoring; then it enters the next process.

[0126] Example 2

[0127] Example 2 is basically the same as Example 1, the only difference is that, as Figure 13 and Figure 14 shown, the driven gear 621 is a semi-gear; the driving gear 631 is a full gear, and the driving gear 631 is meshed with the driven gear 621.

[0128] When the above structure is working, the baffle 622 will block the cut tobacco 9 on the inclined plate 61. When the first toothed sprocket wheel 55 rotates, the second toothed sprocket wheel 632 drives the fixed rod 63 to rotate under the drive of the transmission chain 65. As the fixed rod 63 rotates, it will drive the drive gear 631 to rotate. When the drive gear 631 meshes with the driven gear 621, it will drive the rotating rod 62 to rotate, so that a gap is generated between the baffle 622 and the inclined plate 61, and the cut tobacco 9 will flow into the blanking cylinder 3 through the gap. When the driven gear 621 loses meshing with the drive gear 631, that is, when it rotates to the toothless surface, it loses the driving force. Under the reset action of the torsion spring 64, the rotating rod 62 drives the baffle 622 back to the original position, and blocks the cut tobacco 9 on the inclined plate 61 again, and then proceeds to the next working process.

[0129] Specifically, the subsequent working process is the same as that of Embodiment 1 and will not be repeated here.

[0130] Embodiment 3

[0131] Embodiment 3 is the same as Embodiments 1 and 2. The only difference is that it further includes a paving component 8. The paving component 8 is arranged at the discharge end of the conveyor weighing device 1 and is connected to an external control device.

[0132] As Figures 10 to 12 shown, the paving component 8 includes:

[0133] A fixed cover 81, the lower surface of the fixed cover 81 is fixedly connected to the upper part of the discharge end of the conveyor weighing device 1;

[0134] A vibrator 82, the vibrator 82 is fixedly connected to one side of the fixed cover 81 through a support frame;

[0135] A first movable rod 83, the first movable rod 83 is arranged inside the fixed cover 81;

[0136] Rake nails 84, one ends of several rake nails 84 are connected to the first movable rod 83, and the other ends are in contact with the upper surface of the conveyor belt on the conveyor weighing device 1;

[0137] Among them, the output end of the vibrator 82 extends into the fixed cover 51 and is connected to the first movable rod 83 at this end.

[0138] Specifically, as Figure 11 and Figure 12 shown, it further includes:

[0139] A second movable rod 85, the second movable rod 85 is arranged in parallel with the first movable rod 83, and several rake nails 84 are connected to the lower end of the second movable rod 85;

[0140] Two limiting rods 86, the limiting rods 86 are slidably sleeved in the corresponding first movable rods 84 and second movable rods 85, and one end of the limiting rod 58 is fixedly connected to the inner wall of the fixed cover 81 on the non-vibrator 82 side;

[0141] A fixed rack 87, which is disposed at the middle of the outer wall of the first movable rod 83 and the second movable rod 85;

[0142] The positioning rod 88 has its top rotatably connected to the upper inner wall of the fixed cover 81 , and its lower end is connected to a transmission gear 89 , and both sides of the transmission gear 89 are respectively meshed and connected to the fixed racks 55 of the first movable rod 83 and the second movable rod 85 .

[0143] When in use, it is the same as Example 1 and Example 2, the only difference is that when the tobacco 9 moves into the fixed cover 81, the vibrator 82 will drive the first movable rod 83 to vibrate back and forth in the limiting tube of the limiting rod 86, and while the first movable rod 83 vibrates back and forth, it will drive the fixed rack 87 on the first movable rod 83 to vibrate synchronously, and the second movable rod 85 is also vibrated under the transmission of the transmission gear 89, so that the two movable rods form a cross vibration, and then the tobacco 9 on the conveyor belt is flattened by the nail 84, and the flattened tobacco 9 falls to the next process. In this implementation process, due to the use of a flattening component in the present invention, the function of automatic flattening can be realized during the transmission process of the conveying equipment, avoiding the tobacco in a tangled state in subsequent operations, and at the same time, cross vibration is used to improve the efficiency of tobacco flattening and the looseness of tobacco; and it can ensure that the tobacco remains in a uniform and flat state, avoiding problems such as overlapping, knotting or damage of tobacco; at the same time, the automated operation of the tobacco flattening component reduces manpower input, improves the automation level of the production line, and thus improves production efficiency and ensures product quality.

[0144] Example 4

[0145] This embodiment 4 is the same as the embodiments 1, 2 and 3, with the only difference being that a recovery component 7 may be provided as required, and the recovery component 7 is provided below the external opening side of the feed hopper 4.

[0149] The material collecting box 72 is connected to the other end of the connecting frame 71 and is used for recovering the debris 10 dropped from the chip removal plate 52 .

[0150] Since the present invention is provided with a recycling component, it can achieve the unified collection of cigarette butts, cigarette ash, and debris in shredded tobacco that fall during the cigarette making process, so as to keep the environment clean and hygienic, prevent garbage such as cigarette butts, cigarette ash, and debris in shredded tobacco from polluting the surrounding environment. At the same time, it also facilitates subsequent operators to collect and discard sundries such as cigarette butts, cigarette ash, and debris in shredded tobacco, reducing the subsequent processes that need to be separately processed. It saves time and is efficient while also reducing environmental pollution.

[0151] Specific use and implementation are the same as those in Embodiment 1 to Embodiment 3. The only difference is that after the shredded tobacco 9 enters the feed hopper 4, the sieve plate 51 will screen out the debris 10 in the shredded tobacco 9. The screened debris 10 will fall onto the chip discharge plate 52 and then into the material collection box 72, so as to achieve the unified collection of cigarette butts, cigarette ash, and debris in shredded tobacco that fall during the cigarette making process, keep the environment clean and hygienic, prevent garbage such as cigarette butts, cigarette ash, and debris in shredded tobacco from polluting the surrounding environment. At the same time, it also facilitates subsequent operators to collect and discard sundries such as cigarette butts, cigarette ash, and debris in shredded tobacco, reducing the subsequent processes that need to be separately processed. It saves time and is efficient while also reducing environmental pollution.
