Technical Field
[0001] This invention relates to the field of tobacco machining, and more specifically to a positioning and grinding device for tobacco shredder blades that is easy to calibrate. Background Technology
[0002] Tobacco shredders are specialized equipment used to cut tobacco leaves or stems into uniform fine shreds. They are widely used in tobacco processing production lines. The blades of tobacco shredders are key components used to cut tobacco leaves or stems and can directly affect the shredding quality. During the processing of tobacco shredder blades, they need to be ground.
[0003] Tobacco shredder blades are consumables used in large quantities, thus requiring batch processing. However, most existing blade grinding devices process single blades, resulting in severely insufficient processing efficiency and unsatisfactory grinding quality. Therefore, this paper studies and improves existing structures and shortcomings, proposing a positioning grinding device for tobacco shredder blades that is easy to calibrate. Summary of the Invention
[0004] In order to improve the grinding efficiency and grinding quality of tobacco shredder blades, the purpose of this invention is to provide a tobacco shredder blade positioning grinding device that is easy to calibrate.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a tobacco shredder blade positioning and grinding device for easy calibration, comprising a base plate, a positioning component, and a grinding component. Three carrier plates are fixed to the upper side of the base plate, and a fixing clamp is installed on the upper side of each carrier plate. A moving component is embedded in the middle of each carrier plate, and a positioning component is installed on the upper side of the moving component. A mounting plate is fixed to the upper side of the base plate, and an electric telescopic rod is installed on one side of the mounting plate. A support base is fixed to one end of the electric telescopic rod, and a mounting frame is fixed to the side of the support base. Grinding components are installed on both sides of the mounting frame. Each grinding component includes a driving shaft, a driven shaft, a synchronous belt, a mounting cylinder, and grinding rollers. One driving shaft and two driven shafts are rotatably mounted on one side of the mounting frame, and synchronous pulleys are fixed to the outer sides of both the driving and driven shafts. A synchronous belt is provided between the synchronous pulleys. A mounting cylinder is fixed to the other end of the driving and driven shafts, and grinding rollers are installed inside the mounting cylinder.
[0006] Furthermore, the moving component includes a fixed frame, a drive motor, a lead screw, and a moving sleeve. The drive motor is installed inside the fixed frame, and a lead screw is provided on one side of the drive motor. The moving sleeve is sleeved on the outside of the lead screw.
[0007] Furthermore, the movable component also includes a connecting block, the movable sleeve is slidably connected to the side wall of the fixed frame, the connecting block is fixed on the upper side of the movable sleeve, and a folding dust cover is connected between the connecting block and the two sides of the fixed frame.
[0008] Furthermore, the positioning component includes a movable plate and a threaded cylinder, the movable plate being fixedly connected to the connecting block, and the threaded cylinder being embedded in the middle of the movable plate.
[0009] Furthermore, the positioning assembly also includes a locking block and a movable clamping plate. The locking block is screwed into the internal threads of the threaded cylinder, and one end of the locking block is rotatably connected to the movable clamping plate.
[0010] Furthermore, the positioning component also includes a rubber layer, the movable clamp and the fixed clamp are parallel to each other, and the inner surfaces of both the fixed clamp and the movable clamp are bonded with rubber layers, and the blade body is clamped between the two rubber layers.
[0011] Furthermore, limiting components are installed on both sides of the carrier plate, and the limiting components include side plates and sliding grooves. The side plates are fixedly connected to the carrier plate, and the sliding grooves are provided on the inner side of the side plates.
[0012] Furthermore, the limiting component also includes sliding blocks, with sliding blocks fixed on both sides of the movable clamping plate, and the sliding blocks are slidably connected to the slide groove.
[0013] Furthermore, the support base, mounting frame, and base plate are slidably connected, and a dust cover is installed on one side of the mounting frame.
[0014] Furthermore, the grinding assembly also includes a rotary motor, which is mounted on one side of the drive shaft and located on the upper side of the support base.
[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Equipped with a movable component, when the lead screw is rotated by the drive motor, the movable sleeve can slide smoothly along the side wall of the fixed frame. This allows the positioning component to be moved horizontally as a whole through the connecting block on the upper side of the movable sleeve, so as to flexibly adjust the positioning position and adapt to the blade body of different thicknesses. The folding dust cover connecting the connecting block and the fixed frame can extend synchronously with the movement of the connecting block, which can effectively prevent grinding dust from entering the fixed frame and contaminating the lead screw and movable sleeve.
[0016] 2. Equipped with a positioning component, the threaded cylinder and locking block are threadedly engaged. Rotating the locking block pushes the movable clamping plate closer to the fixed clamping plate, facilitating the clamping and fixing of the blade body. The rubber layer on the inner sides of both the fixed and movable clamping plates enhances clamping friction, preventing blade slippage, and avoids damage to the blade from rigid clamping. Precise positioning via the movable component followed by further locking via the locking block enables accurate positioning and calibration before grinding, reducing repetitive adjustment steps during calibration. During the movement of the movable clamping plate, its side sliding block engages with the sliding groove of the side plate, providing precise guidance and preventing deviation during clamping.
[0017] 3. Equipped with an electric telescopic rod, the electric telescopic rod on the mounting plate can push the support base and mounting frame to slide along the base plate, thereby realizing the adjustment of the feed between the grinding roller and the blade, adapting to the grinding needs of blades with different wear levels; the distributed layout of the three carrier plates can simultaneously perform positioning grinding on three blade bodies, with good batch processing capability; the synchronous operation of the three corresponding grinding rollers can ensure that the blade body cutting edge is evenly stressed, thereby improving the grinding efficiency and grinding quality of the tobacco shredding blade body; the dust cover on the outside of one side of the mounting frame can limit the dust generated by the grinding components to a local area, reducing the impact of dust on power components such as the rotary motor.
[0018] 4. Equipped with a grinding assembly, the grinding rollers of the grinding assembly form line contact with the blade body, which facilitates improved grinding uniformity. One side of the mounting frame adopts a shaft layout of one active shaft and two driven shafts. After the active shaft is driven to rotate by the rotary motor, it can drive the two driven shafts to rotate synchronously through the transmission of the synchronous pulley and synchronous belt. This allows the grinding rollers in the three mounting cylinders to grind the three blade bodies simultaneously, resulting in high processing efficiency. The independent installation of the three grinding rollers facilitates later maintenance and repair. Attached Figure Description

[0021] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] Please see Figures 1-3 This embodiment provides a tobacco shredder blade positioning and grinding device for easy calibration, comprising a base plate 1, a positioning component 5, and a grinding component 12. Three carrier plates 2 are fixed on the upper side of the base plate 1, and a fixing clamp 3 is installed on the upper side of the carrier plates 2. A moving component 4 is embedded in the middle of the carrier plates 2, and the positioning component 5 is installed on the upper side of the moving component 4. The moving component 4 includes a fixing frame 401, a drive motor 402, a lead screw 403, and a moving sleeve 404. The drive motor 402 is installed inside the fixing frame 401, and the lead screw 403 is provided on one side of the drive motor 402. The moving sleeve 404 is sleeved on the outer side of the lead screw 403. The moving component 4 also includes a connecting block 405. The moving sleeve 404 is slidably connected to the side wall of the fixing frame 401. The connecting block 405 is fixed on the upper side of the moving sleeve 404, and a folding dust cover is connected between the connecting block 405 and the two ends of the fixing frame 401. The specific operation is as follows: when the drive motor 402 drives the lead screw 403 to rotate, the moving sleeve 404 can slide smoothly along the side wall of the fixed frame 401. Thus, the connecting block 405 on the upper side of the moving sleeve 404 drives the positioning component 5 to move as a whole, so as to flexibly adjust the position of the positioning component 5 to adapt to the installation of blade bodies 7 of different thicknesses. The folding dust cover connected between the connecting block 405 and the fixed frame 401 can extend synchronously with the movement of the connecting block 405, thereby effectively preventing grinding dust from entering the interior of the fixed frame 401 and contaminating the use of the lead screw 403 and the moving sleeve 404.
[0023] Please see Figure 2 and Figure 3The positioning component 5 includes a movable plate 501 and a threaded cylinder 502. The movable plate 501 is fixedly connected to the connecting block 405. The threaded cylinder 502 is embedded in the middle of the movable plate 501. The positioning component 5 also includes a locking block 503 and a movable clamping plate 504. The locking block 503 is screwed into the internal thread of the threaded cylinder 502. The movable clamping plate 504 is rotatably connected to one end of the locking block 503. The positioning component 5 also includes a rubber layer 505. The movable clamping plate 504 is parallel to the fixed clamping plate 3. The inner surfaces of the fixed clamping plate 3 and the movable clamping plate 504 are both bonded with rubber layers 505. The blade body 7 is clamped between the two rubber layers 505. The specific operation is as follows: the threaded cylinder 502 is threadedly engaged with the locking block 503. Rotating the locking block 503 will push the movable clamping plate 504 to move it closer to the fixed clamping plate 3, so as to achieve clamping and fixing of the blade body 7. The rubber layer 505 bonded to the inner side of the fixed clamping plate 3 and the movable clamping plate 504 can enhance the clamping friction to prevent the blade from slipping, and also avoid damage to the blade caused by rigid clamping. After precise positioning by the movable component 4, it can be further locked by pushing the locking block 503. This can achieve precise positioning and correction before grinding, and also reduce the repeated adjustment steps during correction.
[0024] Please see Figure 1 and Figure 2 Limiting components 6 are installed on both sides of the carrier plate 2. The limiting components 6 include side plates 601 and sliding grooves 602. The side plates 601 are fixedly connected to the carrier plate 2. The sliding grooves 602 are opened on the inner side of the side plates 601. The limiting components 6 also include sliding blocks 603. Sliding blocks 603 are fixed on both sides of the movable clamping plate 504, and the sliding blocks 603 are slidably connected to the sliding grooves 602. The specific operation is as follows: during the movement of the movable clamping plate 504, the sliding block 603 on its side can slide and cooperate with the sliding groove 602 of the side plate 601, thereby providing precise guidance for the movable clamping plate 504 and preventing it from deviating during clamping and use.
[0025] Please see Figure 1 , Figure 4 and Figure 5 An mounting plate 8 is fixed on the upper side of the base plate 1. An electric telescopic rod 9 is installed on one side of the mounting plate 8. A support base 10 is fixed at one end of the electric telescopic rod 9. An mounting frame 11 is fixed on the side of the support base 10. The support base 10, the mounting frame 11 and the base plate 1 are slidably connected. A dust cover is installed on the outside of one side of the mounting frame 11. The specific operation is as follows: the electric telescopic rod 9 on the mounting plate 8 can push the support base 10 and the mounting frame 11 to slide along the base plate 1, thereby realizing the adjustment of the feed amount between the grinding roller 1206 and the blade, adapting to the grinding needs of blades with different wear levels; the distributed layout of the three carrier plates 2 can simultaneously perform positioning grinding on the three blade bodies 7, with better batch processing capability; at the same time, the synchronous operation of the three corresponding grinding rollers 1206 can ensure that the cutting edge of the blade body 7 is subjected to uniform force, thereby improving the grinding efficiency and grinding quality of the tobacco shredding blade body 7; the dust cover on one side of the mounting frame 11 can limit the dust generated by the grinding assembly 12 to a local area, reducing the impact of dust on power components such as the rotary motor 1202.
[0026] Please see Figure 1 and Figure 4 Grinding components 12 are mounted on both sides of the mounting frame 11. The grinding components 12 include a drive shaft 1201, a driven shaft 1203, a timing belt 1204, a mounting cylinder 1205, and a grinding roller 1206. One drive shaft 1201 and two driven shafts 1203 are rotatably mounted on one side of the mounting frame 11. Timing pulleys are fixed on the outer sides of the drive shaft 1201 and the driven shaft 1203. A timing belt 1204 is provided between the timing pulleys. The mounting cylinder 1205 is fixed at the other end of the drive shaft 1201 and the driven shaft 1203. The grinding roller 1206 is installed inside the mounting cylinder 1205. The grinding components 12 also include a rotary motor 1202. A rotary motor 1202 is mounted on one side of the drive shaft 1201. The rotary motor 1202 is located on the upper side of the support base 10. The specific operation is as follows: the grinding roller 1206 of the grinding assembly 12 forms line contact with the blade body 7, which facilitates the improvement of grinding uniformity. The mounting frame 11 adopts a shaft layout of one active rotating shaft 1201 and two driven rotating shafts 1203 on one side. After the active rotating shaft 1201 is driven to rotate by the rotary motor 1202, the two driven rotating shafts 1203 are driven to rotate synchronously through the transmission of the synchronous pulley and the synchronous belt 1204. This allows the grinding rollers 1206 in the three mounting cylinders 1205 to grind the three blade bodies 7 at the same time, which improves the processing efficiency. At the same time, the three grinding rollers 1206 are installed independently, which facilitates later maintenance and repair.
[0027] Working principle: In use, first, the blade body 7 is placed on one side of the fixed clamping plate 3 above the carrier plate 2. Then, the drive motor 402 drives the lead screw 403 to rotate, so that the moving sleeve 404 can slide smoothly along the side wall of the fixed frame 401. This causes the positioning component 5 to move as a whole through the connecting block 405 on the upper side of the moving sleeve 404, so as to flexibly adjust the positioning position and perform preliminary positioning for blade bodies 7 of different thicknesses. Then, rotating the locking block 503 in the threaded cylinder 502 can push the moving clamping plate 504 to move towards the fixed frame 401. The clamping plates 3 come together and lock in place to secure the blade body 7, thereby achieving precise positioning and correction before grinding. In conjunction with the rubber layer 505 on the inner side of the fixed clamping plate 3 and the movable clamping plate 504, the clamping friction is enhanced to prevent the blade from slipping, and the rigid clamping is prevented from damaging the blade. During the movement of the movable clamping plate 504, the sliding block 603 on its side can slide and engage with the sliding groove 602 of the side plate 601, thereby providing precise guidance for the movable clamping plate 504 and preventing it from shifting during clamping. Then, the electric telescopic rod 9 on the mounting plate 8 can push the support base 10 and the mounting frame 11 to slide along the base plate 1, thereby realizing the adjustment of the feed amount between the grinding roller 1206 and the blade, adapting to the grinding needs of blades with different wear levels. The mounting frame 11 adopts a shaft layout with one active rotating shaft 1201 and two driven rotating shafts 1203 on one side. After the rotary motor 1202 drives the active rotating shaft 1201 to rotate, it can drive the two driven rotating shafts 1203 to rotate synchronously through the transmission of the synchronous pulley and synchronous belt 1204, so that the grinding rollers 1206 in the three mounting cylinders 1205 simultaneously grind the three blade bodies 7. The grinding roller 1206 of the grinding assembly 12 forms line contact with the blade body 7, which facilitates the improvement of grinding uniformity. At this time, the distributed layout of the three carrier plates 2 can simultaneously position the three blade bodies 7. The synchronous operation of the three corresponding grinding rollers 1206 can ensure that the cutting edge of the blade body 7 is subjected to uniform force, thereby improving the grinding efficiency and grinding quality of the tobacco shredder blade body 7. The dust cover on the outside of the mounting frame 11 can limit the dust generated by the grinding assembly 12 to a local area, reducing the impact of dust on power components such as the rotary motor 1202. In this way, the entire process of using the tobacco shredder blade positioning grinding equipment that is easy to correct is completed.
