Description

Technical Field

[0001] This invention relates to the field of tobacco shredder technology, specifically to a tobacco shredder and its control method. Background Technology

[0002] The shredder is an important piece of equipment in tobacco processing equipment. It is a major step in the tobacco processing technology. The uniformity of the shredder width and the stability of the shredder play a very important role in the balance of moisture content and filling value of the dried tobacco.

[0003] Currently, in existing tobacco shredders, the cutting blades experience wear during operation, which over time affects their sharpness. Consequently, some tobacco leaves may not be completely cut and may stick together, reducing the quality of the shredded tobacco. Furthermore, it's inconvenient to sharpen the blades while cutting tobacco using existing shredders. Typically, the machine is stopped, and the blades are disassembled for sharpening. This method not only increases the inconvenience for workers but also consumes considerable time and reduces the shredding efficiency of the machine. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a tobacco shredder and its control method, which solves the problem that traditional tobacco shredders cannot simultaneously sharpen the cutting blade while cutting tobacco. Therefore, the cutting blade can be sharpened while cutting tobacco, avoiding the need to stop the shredder and disassemble it for sharpening after the blade wears down to a certain extent. This reduces the trouble and time wasted for workers, while improving the shredding efficiency of the shredder.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tobacco shredder includes a worktable, a shredder fixedly connected to one end of the worktable, a cutting box fixedly connected to the upper surface of the shredder, a cutter provided inside the cutting box, the two ends of the cutter being slidably connected to the inner sidewall of the cutting box via limiting blocks, a driving mechanism above the cutter, a through hole provided inside the shredder, the through hole being aligned with the cutter, a groove provided on the lower surface of the shredder, the groove being below the through hole, a plurality of springs II being symmetrically fixedly connected to the inner side surface of the groove, a grinding strip fixedly connected to one end of each spring II, the two ends of the grinding strip being connected to the shredder via a support assembly, a support frame fixedly connected to the lower surface of one end of the shredder, a sieve frame slidably connected inside the support frame, one end of the sieve frame being fixedly connected to the support frame via a spring III, and a driving assembly installed on the side surface of one end of the shredder.

[0006] Preferably, the drive assembly includes a second motor, one end of which is fixedly connected to a half gear, and a toothed rod is meshed with the side surface of the half gear. One end of the toothed rod is fixedly connected to the other side surface of the screen frame.

[0007] Preferably, half the circumference of the half gear is the same as the length of the rack.

[0008] Preferably, the other end of the second motor is fixedly connected to a pulley assembly, one end of the pulley assembly is fixedly connected to a pulley, a belt is fitted on the side surface of the pulley, a pulley is fitted on the upper end of the belt, and the inner surface of the pulley is connected to the drive mechanism.

[0009] Preferably, the driving mechanism includes a drive shaft, a support plate rotatably connected to the side surface of the drive shaft, the lower end of the support plate being fixedly connected to the upper surface of the cutting box, one end of the drive shaft being fixedly connected to the inner surface of the second pulley, the other end of the drive shaft being fixedly connected to a drive plate, one end of the drive plate being rotatably connected to a push rod, the lower end of the push rod being fixedly connected to a support frame, and the lower end of the support frame being connected to the cutter through a limiting mechanism.

[0010] Preferably, the limiting mechanism includes a limiting plate, with both ends of the limiting plate fixedly connected to the inner wall of the cutting box, and a limiting rod slidably connected inside the limiting plate. The lower end of the limiting rod is fixedly connected to the upper surface of the cutter, and the upper end of the limiting rod is rotatably connected to the lower end of the support frame.

[0011] Preferably, the support mechanism includes symmetrically arranged side plates, one end of which is fixedly connected to the shredding table. The side plates are symmetrically provided with keyways inside, and a support rod is slidably connected inside the keyways. One end of the support rod is fixedly connected to the grinding strip. A spring is sleeved on the side surface of the support rod, and one end of the spring is fixedly connected to the grinding strip.

[0012] Preferably, the other end of the support rod is aligned with the pulley, and a wedge block is fixedly connected to the inner surface of the pulley, with the wedge block corresponding to the other end of the support rod.

[0013] A tobacco shredder and its control method: The specific steps are as follows: Step 1: First, lay the tobacco neatly on the upper surface of the conveyor belt inside the workbench. Then, start motor one. Motor one will drive the conveyor belt to rotate through gear two and gear three, thereby transporting the tobacco into the cutting box. At the same time, the pressure roller can squeeze the tobacco on the upper surface of the conveyor belt to reduce the looseness of the tobacco and prevent the tobacco from slipping during cutting, which would result in the tobacco shreds being of uneven thickness. Step 2: As the tobacco enters the cutting box, the second motor in the drive assembly is started. At this time, the second motor drives the first pulley to rotate through the pulley group. The first pulley drives the drive shaft to rotate through the belt and the second pulley. Then, the drive shaft drives the support frame to move up and down through the drive plate and the push rod. At this time, the support frame will drive the cutter to move up and down through the limit rod. Therefore, the cutter will cut the tobacco that has entered the cutting box into shreds. The cut tobacco shreds will be gradually pushed into the inside of the screen frame for collection. During the downward cutting process, the cutter will pass through the through hole and then insert into the inside of the sharpening strip. Therefore, the sharpening strip will initially sharpen the blade of the cutter. Step 3: As the grinding strip moves in and out of the lower end of the cutter, the pulley drives the wedge block to rotate, which will push the support rod. At this time, the support rod will push the grinding strip to move horizontally. During the movement of the grinding strip, the blade of the cutter can be further sharpened, thereby improving the sharpening effect of the cutter. Step 4: While cutting the tobacco and sharpening the cutter, motor 2 will drive the half gear to rotate. At this time, the half gear will drive the rack to move, thus pushing the screen frame to move away from the cutting table. When the teeth on the side surface of the half gear have completely passed the rack, the screen frame will be bounced back to its original position by spring 3. This process is repeated to screen the tobacco inside the screen frame, thereby removing impurities and small particles from the tobacco.

[0014] This invention provides a tobacco shredder and its control method. Compared with the prior art, it has the following advantages: 1. By using the symmetrical arrangement of the grinding strip at one end of the spring 2 on the inner side of the groove on the lower surface of the cutting table, the support rod in the support mechanism at both ends of the grinding strip, the wedge block on the inner side of the spring 1 and the pulley 1, and the drive assembly, the problem of traditional tobacco shredders not being able to grind the cutting blades while cutting tobacco is solved. Therefore, the cutting blade can be ground while cutting tobacco, avoiding the need to stop the shredder and disassemble the cutting blades for grinding after the blades have worn to a certain extent. This reduces the trouble and time wasted for the workers, and improves the shredding efficiency of the shredder.

[0015] 2. Through the interaction of the half gear fixedly connected to the other end of the motor in the drive assembly and the toothed rod meshing with the side surface of the half gear, the screen frame slidably connected to the upper surface of the support frame and the spring at one end of the screen frame, the tobacco shreds can be screened at the same time as the tobacco is cut, removing impurities and fine particles from the tobacco, thereby improving the quality of the tobacco shreds.

The pulley 502 is aligned, and a wedge block 303 is fixedly connected to the inner surface of the pulley 502. The wedge block 303 corresponds to the other end of the support rod 307. The support rod 307, spring 306 and wedge block 303 on the inner surface of the pulley 502 cooperate with each other so that when the cutter 201 passes through the through hole 309 and is inside the sharpening strip 305 during the process of cutting tobacco, it can push the sharpening strip 305 to move horizontally back and forth, thereby sharpening the blade of the cutter 201.

[0026] As a technical optimization of the present invention, a pressure roller 102 is installed on the upper surface of one end of the workbench 1. A gear 103 is fixedly connected to one end of the pressure roller 102. A gear 3 106 is meshed with the side surface of the gear 103. A gear 2 104 is meshed with the side surface of the gear 3 106. A motor 105 is fixedly connected to one side surface of the gear 2 104. A conveyor belt 101 is connected to one side surface of the gear 3 106 through the workbench 1 via a rotating shaft.

[0027] A tobacco shredder and its control method: The specific steps are as follows Step 1: First, lay the tobacco neatly on the upper surface of the conveyor belt 101 inside the workbench 1. Then, start the motor 105. The motor 105 will drive the conveyor belt 101 to rotate through the gear 2 104 and the gear 3 106, thereby transporting the tobacco into the cutting box 2. At the same time, the pressure roller 102 can squeeze the tobacco on the upper surface of the conveyor belt 101 to reduce the looseness of the tobacco and prevent the tobacco from slipping during cutting, which would result in the tobacco shreds being of uneven thickness. Step 2: As the tobacco enters the cutting box 2, the second motor 5 in the drive assembly is started. At this time, the second motor 5 drives the first pulley 502 to rotate through the pulley group 501. The first pulley 502 drives the drive shaft 204 to rotate through the belt 503 and the second pulley 504. Then, the drive shaft 204 drives the support frame 207 to move up and down through the drive plate 205 and the push rod 206. At this time, the support frame 207 will drive the cutter 201 to move up and down through the limit rod 208. Therefore, the cutter 201 will cut the tobacco that has entered the cutting box 2 into shreds. At this time, the cut tobacco shreds will be gradually pushed into the inside of the screen frame 401 for collection. During the downward cutting process of the cutter 201, it will pass through the through hole 309 and then insert into the inside of the sharpening strip 305. Therefore, the sharpening strip 305 will perform preliminary sharpening on the blade of the cutter 201. Step 3: As the grinding strip 305 moves in and out of the lower end of the cutter 201, the pulley 502 drives the wedge block 303 to rotate, which will push the support rod 307. At this time, the support rod 307 will push the grinding strip 305 to move horizontally. During the movement of the grinding strip 305, the blade of the cutter 201 can be further sharpened, thereby improving the sharpening effect of the cutter 201. Step 4: While cutting the tobacco and sharpening the cutter 201, motor 2 5 will drive the half gear 405 to rotate. At this time, the half gear 405 will drive the rack 403 to move. Therefore, the half gear 405 will push the screen frame 401 to move, thereby pushing the screen frame 401 away from the cutting table 3. When the teeth on the side surface of the half gear 405 have completely passed the rack 403, the screen frame 401 will be bounced back to its original position by spring 3 402. This process is repeated to screen the tobacco inside the screen frame 401, thereby removing impurities and small particles from the tobacco.
