Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette industry, specifically relating to a novel oil-free splitting knife device for cigarette making machines. Background Technology

[0002] Cigarettes are typically cut using a cleaver during the production process, but current cleaver devices have the following problems in use:

[0003] 1) It can easily cause lubricating oil leakage and affect product quality.

[0004] The splitting device uses lubricating oil to lubricate the transmission gears and relies on a sealing structure to seal the lubricating oil. However, it is prone to aging during continuous operation and often leaks oil. Since the splitting device is in direct contact with the tobacco, once the lubricating oil leaks, it will directly contaminate the tobacco and affect the product quality.

[0005] 2) The synchronous adjustment process is cumbersome and difficult.

[0006] The mechanical system adjustment process of the existing splitting device is complex and difficult. Synchronization anomalies frequently occur between the front and rear splitting discs, between the splitting disc and the brush wheel, and between the splitting groove and the cutting disc, affecting the efficiency of the entire production process and the stability of product quality.

[0007] 3) The relative position adjustment of the splitting disc and the brushing wheel is slow, and the operation of adjusting the gap between the two splitting discs after changing the splitting disc of different cigarettes is cumbersome. Utility Model Content

[0008] In order to solve the above-mentioned technical problems in the prior art, this utility model provides a new type of oil-free splitting knife device for cigarette machines that is simple in structure, easy to operate, and ensures that the cigarettes are not contaminated by lubricating oil.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel oil-free splitting blade device for cigarette making machines, comprising a vertically arranged mounting plate, a mounting column fixedly provided on the front side of the mounting plate, the mounting column being horizontally arranged along the front-rear direction in its length direction, a front servo motor and a rear servo motor provided on the rear side of the mounting column, a front splitting blade disc being mounted on the upper end of the main shaft of the front servo motor, a rear splitting blade disc being mounted on the upper end of the main shaft of the rear servo motor, a blade disc gap adjustment device for adjusting the distance between the front servo motor and the rear servo motor being provided on the mounting column, and a blade disc cleaning structure being provided on the mounting plate.

[0010] The cutter head clearance adjustment device includes a lead screw, a front nut slide, and a rear nut slide. From front to back, the right side of the mounting column has a through-type front slide groove, a front through-rod groove, a wrench receiving groove, a rear through-rod groove, and a rear slide groove. The lead screw has the front slide groove, front through-rod groove, wrench receiving groove, rear through-rod groove, and rear slide groove arranged horizontally. The portion of the lead screw's outer diameter within the front slide groove has a front thread section, and the portion within the rear slide groove has a rear thread section. The threads of the front and rear thread sections have opposite directions. The front nut slide is assembled in the front slide groove and screwed to the front thread section of the lead screw. The rear nut slide is assembled in the rear slide groove and screwed to the rear thread section of the lead screw. The outer diameter of the lead screw has a hexagonal structure at the wrench receiving groove. The front nut slide is connected to the base of the front servo motor via a front connecting bolt, and the rear nut slide is connected to the base of the rear servo motor via a rear connecting bolt.

[0011] A front limiting plate is provided on the right side of the mounting column at the front through-rod slot via a front limiting screw, and a rear limiting plate is provided on the right side of the mounting column at the rear through-rod slot via a rear limiting screw.

[0012] The mounting post has countersunk holes above and below the front slide groove, and countersunk holes above and below the rear slide groove. The length of the countersunk holes is horizontal along the front-rear direction. A front positioning bolt for connecting to the base of the front servo motor passes through the front countersunk hole, and a rear positioning bolt for connecting to the base of the rear servo motor passes through the rear countersunk hole.

[0013] The blade cleaning structure includes a lifting cylinder, a cleaning servo motor, and a brush wheel. The lifting cylinder is fixedly mounted on the rear side of the mounting plate. The piston rod of the lifting cylinder is connected to a lifting connecting plate that passes through the mounting plate. A support is provided on the front side of the lifting connecting plate. The cleaning servo motor is fixedly mounted on the front side of the support. The main shaft of the cleaning servo motor is perpendicular to the main shaft of the front servo motor. The outer end of the main shaft of the cleaning servo motor extends to the position between the main shafts of the front and rear servo motors. The brush wheel is installed on the outer end of the main shaft of the cleaning servo motor and is located below the front and rear blade discs.

[0014] A cover plate is installed on the right side of the mounting column via countersunk screws.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] 1) The front splitting disc is driven by a front servo motor, the rear splitting disc is driven by a rear servo motor, and the brush wheel is driven by a cleaning servo motor. This eliminates the gear shaft and helical gear transmission mechanism of the original splitting device. The brush wheel, front splitting disc, and rear splitting disc are all directly driven by servo motors, achieving gearless transmission and oil-free operation in the splitting device, completely solving the oil leakage problem. Furthermore, direct servo motor drive reduces transmission noise and facilitates maintenance.

[0017] 2) The brush wheel moves up and down by extending and retracting the lifting cylinder. A high-speed solenoid valve is installed on the air supply line of the lifting cylinder. By controlling the solenoid valve, the lifting cylinder can be activated at any time to raise or lower the height of the brush wheel. When it descends, the brush wheel disengages from the splitting disc (for easy equipment maintenance and observation). When it rises, the brush wheel contacts the bottom surfaces of the front and rear splitting discs. The cleaning servo motor is activated to clean the front and rear splitting discs, brushing away the tobacco shreds adhering to the cut cigarettes.

[0018] 3) When it is necessary to adjust the gap between the front and rear chopping discs, operate the disc gap adjustment device for adjustment. The specific adjustment process is as follows: First, loosen the front and rear positioning bolts. Then, use a wrench to hold the hexagonal structure in the middle of the lead screw, turn the wrench to drive the lead screw to rotate. The front nut slide, which is screwed to the front thread section of the lead screw, and the rear nut slide, which is screwed to the rear thread section of the lead screw, move along the front and rear slides respectively. Since the threads of the front and rear thread sections of the lead screw are in opposite directions, the distance between the front and rear nut slides increases or decreases when the lead screw rotates in the forward or reverse direction. This allows the gap between the front and rear chopping discs to be adjusted. After adjustment, tighten the front and rear positioning bolts.

[0019] 4) The front and rear limit plates are used to keep the lead screw within the front and rear through-rod slots, respectively. The wrench receiving slot runs vertically along its length, facilitating wrench engagement with the hexagonal structure for rotation. Tightening the front and rear positioning bolts ensures that the bases of both the front and rear servo motors are pressed against the mounting post, thus positioning the distance between the front and rear servo motors. The cover plate conceals many slots on the rear side of the mounting post, providing both safety and aesthetic appeal.

[0020] 5) As the brush wheel rises, driven by the lifting cylinder, it simultaneously contacts the edges of the front and rear splitting discs. The cleaning servo motor drives the brush wheel to rotate, cleaning the tobacco debris adhering to the front and rear splitting discs. During descent, the top of the brush wheel disengages from the bottom surface of the front and rear splitting discs, and the cleaning servo motor shuts off.

[0021] In summary, this invention is scientifically sound and simple in structure, avoiding the contamination of cigarettes by lubricating oil. Three servo motors are individually controlled for opening, closing, and rotation speed, enabling rapid adjustment of the relative position of the splitting disc and the brush wheel. The relative position and gap between the splitting discs can be quickly adjusted after replacing them with different cigarette types. The brush wheel can be disengaged from the splitting disc, facilitating equipment maintenance and observation. Attached Figure Description

The outer circle of the lead screw 7 is provided with a hexagonal structure 15 at the wrench receiving groove 12. The front nut slide 8 is connected to the base of the front servo motor 3 through the front connecting bolt 16. The rear nut slide 9 is connected to the base of the rear servo motor 4 through the rear connecting bolt 17.

[0028] On the right side of the mounting post 2, a front limiting plate 19 is provided at the front through rod groove 11 via a front limiting screw 18, and on the right side of the mounting post 2, a rear limiting plate 21 is provided at the rear through rod groove 13 via a rear limiting screw 20.

[0029] The mounting post 2 has a front countersunk hole 22 above and below the front slide groove 10, and a rear countersunk hole 23 above and below the rear slide groove 14. The length of the front countersunk hole 22 and the rear countersunk hole 23 are both horizontally arranged in the front-to-back direction. A front positioning bolt 24 connected to the base of the front servo motor 3 passes through the front countersunk hole 22, and a rear positioning bolt 25 connected to the base of the rear servo motor 4 passes through the rear countersunk hole 23.

[0030] The blade cleaning structure includes a lifting cylinder 26, a cleaning servo motor 27, and a brush wheel 28. The lifting cylinder is fixedly mounted on the rear side of the mounting plate 1. The piston rod of the lifting cylinder 26 is connected to a lifting connecting plate that passes through the mounting plate 1. A support 29 is provided on the front side of the lifting connecting plate. The cleaning servo motor 27 is fixedly mounted on the front side of the support 29. The main shaft of the cleaning servo motor 27 is perpendicular to the main shaft of the front servo motor 3. The outer end of the main shaft of the cleaning servo motor 27 extends to the position between the main shaft of the front servo motor 3 and the main shaft of the rear servo motor 4. The brush wheel 28 is installed on the outer end of the main shaft of the cleaning servo motor 27 and is located below the front splitting disc 5 and the rear splitting disc 6.

[0031] A cover plate 30 is provided on the right side of the mounting column 2 via countersunk screws.

[0032] The working principle and beneficial effects of this utility model are as follows:

[0033] 1) The front splitting disc 5 is driven by the front servo motor 3, the rear splitting disc 6 is driven by the rear servo motor 4, and the brush wheel 28 is driven by the cleaning servo motor 27. This eliminates the gear shaft and helical gear transmission mechanism of the original splitting device. The brush wheel 28, the front splitting disc 5, and the rear splitting disc 6 are all directly driven by servo motors, achieving gearless transmission and oil-free operation in the splitting device, thus completely solving the oil leakage problem. Furthermore, direct drive by servo motors reduces transmission noise and facilitates maintenance.

[0034] 2) The lifting cylinder 26 extends and retracts to move the brush wheel 28 up and down. A high-speed solenoid valve is installed on the air supply line of the lifting cylinder 26. By controlling the solenoid valve, the lifting cylinder 26 can be activated at any time to raise or lower the height of the brush wheel 28. When it descends, the brush wheel 28 disengages from the splitting disc (for easy equipment maintenance and observation). When it rises, the brush wheel 28 contacts the bottom surfaces of the front splitting disc 5 and the rear splitting disc 6. The cleaning servo motor 27 is activated to clean the front splitting disc 5 and the rear splitting disc 6, brushing away the tobacco shreds adhering to the cut cigarettes.

[0035] 3) When it is necessary to adjust the gap between the front chopping disc 5 and the rear chopping disc 6, the chopping disc gap adjustment device is operated for adjustment. The specific adjustment process is as follows: First, loosen the front positioning bolt 24 and the rear positioning bolt 25. Then, use a wrench to hold the hexagonal structure 15 in the middle of the lead screw 7, turn the wrench to drive the lead screw 7 to rotate. The front nut slide 8, which is screwed to the front thread section of the lead screw 7, and the rear nut slide 9, which is screwed to the rear thread section of the lead screw 7, move along the front slide groove 10 and the rear slide groove 14, respectively. Since the threads of the front and rear thread sections of the lead screw 7 are in opposite directions, the gap between the front nut slide 8 and the rear nut slide 9 increases or decreases when the lead screw 7 rotates in the forward or reverse direction. In this way, the gap between the front chopping disc 5 and the rear chopping disc 6 can be adjusted. After the adjustment is in place, tighten the front positioning bolt 24 and the rear positioning bolt 25.

[0036] 4) The front limiting plate 19 and the rear limiting plate 21 are used to limit the lead screw 7 to remain within the front through-rod groove 11 and the rear through-rod groove 13. The wrench receiving groove 12 is along the vertical direction, making it convenient for the wrench to engage the hexagonal structure 15 for rotation. After tightening the front positioning bolt 24 and the rear positioning bolt 25, the bases of the front servo motor 3 and the rear servo motor 4 can be pressed against the mounting post 2, thereby positioning the distance between the front servo motor 3 and the rear servo motor 4. The cover plate 30 covers the multiple grooves on the rear side of the mounting post 2, serving a safe and aesthetic purpose.

[0037] 5) When the brush wheel 28 rises under the drive of the lifting cylinder 26, it simultaneously contacts the edges of the front splitting disc 5 and the rear splitting disc 6. The cleaning servo motor 27 drives the brush wheel 28 to rotate, cleaning the tobacco debris adhering to the front splitting disc 5 and the rear splitting disc 6. When descending, the top of the brush wheel 28 disengages from the bottom surface of the front splitting disc 5 and the rear splitting disc 6, and the cleaning servo motor 27 shuts off.

[0038] In this invention, the front servo motor 3, rear servo motor 4, cleaning servo motor 27, lifting cylinder 26, brush wheel 28, front splitting disc 5, and rear splitting disc 6 are all existing technologies and are commercially available. Their structure and working principle will not be described in detail. Furthermore, the automatic control of the front servo motor 3, rear servo motor 4, cleaning servo motor 27, and lifting cylinder 26 does not involve any new computer program.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
