[0067] Embodiment 1

[0068] This embodiment provides an online tobacco leaf cutting device. Figure 1 or Figure 2 to Figure 5The online tobacco leaf cutting device comprises a feeding conveying mechanism 1, a bracket 2, a material extruding conveying mechanism 3 and a slitting mechanism 4. The bracket 2 is arranged on the feeding conveying mechanism 1, and the slitting mechanism 4 comprises a lifting driving member 41, which is arranged on the bracket 2, and the lifting driving member 41 drives the material extruding conveying mechanism 3 to be rotatably connected relative to the feeding conveying mechanism 1. The slitting mechanism 4 also comprises a cutter driving member 42, a cutter transmission member 43 and a plurality of upper cutters 44, all of which are arranged on the material extruding conveying mechanism 3. The cutter driving member 42 drives the cutter transmission member 43 and drives the upper cutters 44 to rotate and cut tobacco leaves.

[0069] Here, the functions of each mechanism are briefly described: the feed conveying mechanism 1 is responsible for transporting tobacco leaves from the feed inlet of the feed conveying mechanism 1 to the discharge outlet of the feed conveying mechanism 1. The transport direction L of the tobacco leaves is as follows: Figure 2 The cutting mechanism 4 is responsible for cutting the tobacco leaves in transportation.

[0070] In one specific embodiment, see Figure 1 or Figure 2 to Figure 5 The feed conveying mechanism 1 includes a feed left side plate 13, a feed right side plate 14 and a transport member. The transport member is arranged between the feed left side plate 13 and the feed right side plate 14, and the transport member is responsible for transporting tobacco leaves. Figure 1 to Figure 5 The bracket 2 includes a left bracket 21, a right bracket 22 and a crossbeam 23. The left bracket 21 is arranged on the left feeding plate 13, the right bracket 22 is arranged on the right feeding plate 14, and the crossbeam 23 spans the top of the left bracket 21 and the right bracket 22, and one end is connected to the top of the left bracket 21, and the other end is connected to the right bracket 22.

[0071] In one specific embodiment, see Figure 1 or Figure 2 to Figure 5 The slitting mechanism 4 further includes a push cylinder base 45, a push cylinder swivel seat 46 and a push cylinder force frame 47. The push cylinder base 45 is arranged on the bracket 2, and the push cylinder swivel seat 46 is rotatably connected to the push cylinder base 45. The lifting drive member 41 is connected to the push cylinder swivel seat 46, and the push cylinder force frame 47 is arranged on the extrusion conveying mechanism 3. The lifting drive member 41 includes a push rod head, and the push rod head is connected to the push cylinder force frame 47.

[0072] In order to explain in detail the above-mentioned "the lifting drive member 41 drives the extrusion conveying mechanism 3 to be rotatably connected with the feed conveying mechanism 1", a specific embodiment is provided here: First, the "driven rotation" part is explained. Figure 6 The extrusion conveying mechanism 3 further includes an extrusion left plate 36 disposed on the left side of the extrusion conveying mechanism 3 and an extrusion right plate 37 disposed on the right side of the extrusion conveying mechanism 3. Figure 6The extrusion conveying mechanism 3 further includes an upper active roller 31, which crosses the end of the extrusion left plate 36 and the end of the extrusion right plate 37. The above arrangement enables the extrusion conveying mechanism 3 to rotate around the upper active roller 31, which is equivalent to the upper active roller 31 being the rotation axis of the extrusion conveying mechanism 3, thereby realizing the "driven rotation" part.

[0073] Next, the "active rotation" part is explained. In order to better understand the "active rotation", the lifting drive member 41 uses a push cylinder. The push cylinder generally includes a push cylinder body and a push rod. The push rod is arranged in the push cylinder body and performs axial linear motion in the push cylinder body. Since the principle of the push cylinder is relatively simple, it will not be repeated here. Figure 1 , the slitting mechanism 4 also includes a push cylinder base 45, a push cylinder swivel 46 and a push cylinder force frame 47. The push cylinder base 45 is arranged on the crossbeam 23, and the push cylinder swivel 46 is rotatably connected to the push cylinder base 45. It is worth noting that the rotatable connection between the push cylinder swivel 46 and the push cylinder base 45 is consistent with the setting method of "driven rotation" above, so it is not repeated here. The push cylinder is connected to the push cylinder swivel 46, and the push cylinder force frame 47 spans the extrusion conveying mechanism 3, and one end is connected to the extrusion left plate 36, and the other end is connected to the extrusion right plate 37. The push rod head of the push cylinder is connected to the push cylinder force frame 47. When the push rod head of the push cylinder is pushed out / retracted, the driving force of the push cylinder is converted into a rotational force, so that the discharge end of the extrusion conveying mechanism 3 is continuously tilted upward, realizing "active rotation". In the process that the discharge end of the extrusion conveying mechanism 3 is continuously tilted upward, the feed end of the extrusion conveying mechanism 3 rotates around the upper active roller 31 to realize "driven rotation". In addition, if we use a metaphor, the movement mode of "active rotation" and "driven rotation" is similar to: the suspension bridge built over the moat in the ancient city, with the iron chain of the suspension bridge replaced by a push cylinder.

[0074] As a supplement, the lifting drive member 41 is generally a push cylinder, which can be a pneumatic push cylinder or an electric push cylinder. The upper cutter 44 is generally a commercially available circular serrated blade.

[0075] In one specific embodiment, see Figure 6 In addition to the upper active roller 31, the extrusion conveying mechanism 3 also includes an upper driven roller 32 and a plurality of extrusion conveying belts 33. Each extrusion conveying belt 33 is arranged around the outer portion of the upper active roller 31 and the upper driven roller 32. Figure 1 The upper active roller 31 is provided with extension sections toward the outside of the left extrusion plate 36 and the right extrusion plate 37. Figure 2 or Figure 3 The left feed plate 13 is provided with a left transfer plate, and the left transfer plate is provided with a left opening, see Figure 4 or Figure 5 The right feed plate 14 is provided with a right transfer plate, and the right transfer plate is provided with a right opening. Figure 2 or Figure 3 The left extension of the upper active roller 31 passes through the left opening, and further reference is made to Figure 4 or Figure 5 The right extension section of the upper active roller 31 passes through the right opening. Figure 4 or Figure 5 The cross beam 23 is also provided with an upper active roller drive motor 31.1, and the drive shaft of the upper active roller drive motor 31.1 is chain-connected to the right extension section of the upper active roller 31. Figure 7 An extrusion conveyor belt interval D is provided between each adjacent extrusion conveyor belt 33, and the number of upper cutters 44 is the same as the number of extrusion conveyor belt intervals D. At the same time, each upper cutter 44 is sequentially arranged in the extrusion conveyor belt intervals D.

[0076] In one specific embodiment, see Figure 8 and Fig. 9 The upper cutter 44 includes a left upper cutter 44.1, a middle upper cutter 44.2 and a right upper cutter 44.3, and the extrusion conveyor belt interval D includes a left conveyor belt interval D1, a middle conveyor belt interval D2 and a right conveyor belt interval D3. The left upper cutter 44.1 is provided in the left conveyor belt interval D1, the middle upper cutter 44.2 is provided in the middle conveyor belt interval D2, and the right upper cutter 44.3 is provided in the right conveyor belt interval D3. Figure 7 The cutter transmission member 43 includes a main transmission shaft 43.1, a left transmission shaft 43.2, a right transmission shaft 43.3, a first middle transmission shaft 43.4 and a second middle transmission shaft 43.5. The main transmission shaft 43.1 crosses the left extrusion plate 36 and the right extrusion plate 37, and the main transmission shaft 43.1 is provided with extension sections to the outside of the left extrusion plate 36 and the outside of the right extrusion plate 37. The left transmission shaft 43.2 penetrates the left extrusion plate 36, and the right transmission shaft 43.3 penetrates the right extrusion plate 37. Figure 7 The left transmission shaft 43.2 is provided at one end outside the left side plate 36 of the extrusion material, and is chain-connected to one end of the total transmission shaft 43.1 extending to the outside of the left side plate 36 of the extrusion material. The left transmission shaft 43.2 is provided at one end inside the left side plate 36 of the extrusion material, and is connected to the upper left cutter 44.1. Similarly, the right transmission shaft 43.3 is provided at one end outside the right side plate 37 of the extrusion material, and is chain-connected to one end of the total transmission shaft 43.1 extending to the outside of the right side plate 37 of the extrusion material. The right transmission shaft 43.3 is provided at one end inside the right side plate 37 of the extrusion material, and is connected to the upper right cutter 44.3. Figure 7, a middle-upper cutter 44.2 adapter plate is also provided on the crossbeam 23, and the first middle transmission shaft 43.4 and the second middle transmission shaft 43.5 are respectively arranged through the middle-upper cutter 44.2 adapter plate. At the same time, one end of the first middle transmission shaft 43.4 is connected to the main transmission shaft 43.1 chain, and the other end is connected to one end of the second middle transmission shaft 43.5, and the other end of the second middle transmission shaft 43.5 is connected to the middle-upper cutter 44.2 chain. In addition, a relay gear is also provided on the middle-upper cutter 44.2 adapter plate, and the relay gear is arranged in the link constructed by the first middle transmission shaft 43.4 and the second middle transmission shaft 43.5. The setting of the relay gear can reduce the frequency of disconnection and chain drop in the link, making the above-mentioned link more stable during transmission, and also improving the safety of the link.

[0077] In one specific embodiment, see Figure 8 , further comprising a lower knife roller 11, which is arranged at the discharge end of the feed conveying mechanism 1. A lower knife roller drive motor 11.1 is provided on one side of the feed conveying mechanism 1, and the drive shaft of the lower knife roller drive motor 11.1 is connected to the lower knife roller 11. More specifically, a plurality of lower knife roller intervals T are provided on the lower knife roller 11, and a lower cutter 12 is provided in each lower knife roller interval T. The number of lower knife roller intervals T is the same as that of the extrusion conveyor belt interval D, and the positions correspond. It is worth noting that the lower cutter 12 uses a commercially available circular serrated blade, and at the same time, the diameter of the upper cutter 44 is generally much larger than the diameter of the lower cutter 12. In addition, the lower cutter 12 is coaxially arranged with the lower knife roller 11, and when the lower knife roller drive motor 11.1 is in operation, the lower knife roller 11 and the lower cutter 12 should rotate synchronously. In addition, the diameter of the lower knife roller 11 is generally smaller than the diameter of the upper active roller 31, and the diameter of the lower knife roller 11 is 100-140 mm. The positional relationship between the upper cutter 44 and the lower cutter 12 is now described by way of example: Figure 8 See also Fig. 9 , the lower blade roller interval T includes the lower left blade roller interval T1, the middle lower blade roller interval T2 and the lower right blade roller interval T3. The lower cutter 12 includes the lower left cutter 12.1, the middle lower cutter 12.2 and the lower right cutter 12.3. The lower left cutter 12.1 is arranged in the lower left blade roller interval T1, the middle lower cutter 12.2 is arranged in the middle lower blade roller interval T2, and the lower right cutter 12.3 is arranged in the lower right blade roller interval T2. The lower left blade roller interval T1 corresponds to the left conveyor belt interval D1, the middle lower blade roller interval T2 corresponds to the middle conveyor belt interval D2, and the lower right blade roller interval T2 corresponds to the right conveyor belt interval D3. Taking the upper left cutter 44.1 and the lower left cutter 12.1 as an example, continue to refer to Figure 8 See also Fig. 9 When cutting tobacco leaves, the upper left cutter 44.1 and the lower left cutter 12.1 alternately cut the tobacco leaves passing through the left conveyor belt interval D1 and the lower left knife roller interval T1.

[0078] In one specific embodiment, see Figure 6 A cross brace 37 for an extrusion conveyor is provided between the left extrusion plate 31 and the right extrusion plate 32. The cross brace 37 for an extrusion conveyor plays a role in strengthening the support of the extrusion conveyor mechanism 3. Figure 6 A plurality of rollers 35 are provided between the left extrusion plate 36 and the right extrusion plate 37, and the rollers 35 support each extrusion conveyor belt 33. As a supplementary explanation, when the extrusion conveyor belt 33 rotates around the upper active roller 31 and the upper driven roller 32, a large space will be left in the extrusion conveyor belt 33, and the flowing air in this part of the space will interfere with the rotation of the extrusion conveyor belt 33. Therefore, each roller 35 supports each extrusion conveyor belt 33, so that the space in each extrusion conveyor belt 33 becomes smaller, reducing the interference of each extrusion conveyor belt 33 during rotation. In addition, each extrusion conveyor belt 33 transports tobacco leaves in the feeding conveying mechanism 1, which can provide additional friction for the advancement of the tobacco leaves.

[0079] In a supplementary embodiment, a first dust cover is provided on the upper cutter 44, a second dust cover is provided at the chain connection between the left transmission shaft 43.2 and the main transmission shaft 43.1, and a third dust cover is provided at the chain connection between the right transmission shaft 43.3 and the main transmission shaft 43.1. The above dust covers can prevent dust from entering to ensure the safety of the operation of the device.

[0080] The tobacco leaf online cutting device includes two states: closed state and cutting state. 1) In the closed state, refer to Figure 2 and Figure 4 , the push rod of the push cylinder retracts, causing the discharge end of the extrusion conveying mechanism 3 to tilt upward, thereby causing the upper cutter 44 to move away from the feeding conveying mechanism 1. In this state, the upper cutter 44 cannot effectively cut the tobacco leaves. 2) In the cutting state, refer to Figure 3 and Figure 5 , the push rod of the push cylinder is pushed out, so that the discharge end of the extrusion conveying mechanism 3 collapses downward, and then the upper cutter 44 is close to the feeding conveying mechanism 1, and forms a cross or scissor shape with the feeding conveying mechanism 1. In this state, when the tobacco leaves move toward the discharge end of the feeding conveying mechanism 1, they will be cut by the upper cutters 44.

[0081] This embodiment also provides a method for using and operating the tobacco leaf cutting device, which is described in detail as follows:

[0082] 1) When the online tobacco leaf cutting device is not started, it should be in a "closed state", that is, the push rod of the push cylinder is retracted, so that the discharge end of the extrusion conveying mechanism 3 is tilted upward, and then the upper cutter 44 is away from the feed conveying mechanism 1, thereby ensuring the safety of the assembly line.

[0083] 2) When preparing to start the online tobacco leaf cutting device, first start the cutting mechanism 4. Push the push rod of the push cylinder to make the discharge end of the extrusion conveying mechanism 3 collapse downward, so that the upper cutter 44 is close to the feeding conveying mechanism 1 and forms a cross or scissor shape with the feeding conveying mechanism 1.

[0084] 3) Next, refer to Figure 7 , start the upper active roller drive motor 31.1, so that the upper active roller 31 rotates, thereby driving each extrusion conveyor belt 33 to rotate around the upper active roller 31 and the upper driven roller 32. At the same time, start the cutter drive 42, and the cutter drive 42 and the main transmission shaft 43.1 are driven by a chain, so that the main transmission shaft 43.1 rotates synchronously with the cutter drive 42. At the same time, continue to refer to Figure 7 The main transmission shaft 43.1 drives the left transmission shaft 43.2, the right transmission shaft 43.3 and the first middle transmission shaft 43.4 to rotate synchronously through chain transmission. Then, the left transmission shaft 43.2 drives the left upper cutter 44.2 to rotate, the right transmission shaft 43.3 drives the right upper cutter 44.4 to rotate, the first middle transmission shaft 43.4 drives the second middle transmission shaft 43.5 to rotate through chain transmission, and the second middle transmission shaft 43.5 drives the middle upper cutter 44.2 to rotate.

[0085] 4) Finally, see Figure 3 , Figure 5 and Figure 8 , start the feed conveying mechanism 1 and the lower knife roller drive motor 11.1, and the lower knife roller drive motor 11.1 drives the lower knife roller 11 and the lower cutter 12 to rotate. When the feed conveying mechanism 1 transports tobacco leaves to the discharge end of the feed conveying mechanism 1, the tobacco leaves touch the rotating upper left cutter 44.1 and lower left cutter 11.1, the middle upper cutter 44.2 and the middle lower cutter 11.2, the upper right cutter 44.3 and the lower right cutter 11.3, so that the tobacco leaves are continuously cut online during transportation. So far, the function of the tobacco leaf cutting device to cut tobacco leaves is realized.

[0086] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
