The filament cutter is the most important production equipment on a tobacco filament production line, and the gap between a blade and a knife gate of the filament cutter directly influences the width of tobacco filaments, so that the quality of the tobacco filaments is influenced. Therefore, the key for guaranteeing the shredding quality is to guarantee the clearance between the blade and the knife gate, and when the condition that the clearance between the blade and the knife gate can not be shredded normally, such as diamond abrasion, knife gate replacement and the like, is generated, the clearance between the knife gate needs to be adjusted.
In the prior art, the following method is adopted to adjust the clearance between the blade and the knife gate of the filament cutter. First, the position of the shredder blades is determined. Pasting cigarette paper in the middle and at two ends of the blade, wherein the thickness of the cigarette paper is the required gap between the blade and the knife gate, uniformly coating a small amount of blue ink on three positions corresponding to the knife gate, and then rotating the knife roller by hand to enable the blade stuck with the cigarette paper to pass through the knife gate. If the blue color is uniformly coated on the cigarette paper, the gap is ideal, and the cigarette paper is cut off, so that the gap is too small; if the cigarette paper is not blue, the gap is too large, and the position needs to be adjusted again by manual feed. Next, the position of the grinding wheel is determined. After the position of the blade is determined, the blade is shaken to the position of a grinding wheel by a hand-operated knife roller, the grinding wheel is manually moved downwards to touch the blade, and the position of the grinding wheel is a standard position. Then, the positions of the other blades are determined. And taking the grinding wheel as a reference, manually shaking other blades to be in light contact with the grinding wheel in sequence, and determining the positions of all the blades. Finally, the position of the diamond is determined. And (4) taking the grinding wheel as a reference, adjusting the diamond to be in light contact with the grinding wheel, and determining the position of the diamond. After the position relations between the blade and the knife gate, between the grinding wheel and the diamond and between the blade and the grinding wheel are determined, the value of the gap between the blade and the knife gate is also determined. And when the clearance distance between the blade and the knife gate meets the shredding requirement, finishing the adjusting process, and if the clearance distance between the blade and the knife gate does not meet the shredding requirement, repeating the steps of the method until the clearance distance between the blade and the knife gate meets the shredding requirement.
When the method is adopted to adjust the gap between the blade and the knife gate, an operator needs to judge and determine the positions of the blade, the grinding wheel and the diamond according to own experience and sense through the mutual touch and scratch conditions among the blade, the grinding wheel and the diamond, and judge whether the positions of the blade, the grinding wheel and the diamond meet the requirements. This requires the operator to have a rich adjustment experience, and has the disadvantage of low adjustment accuracy. Due to the low adjustment precision, the adjustment steps are repeated for many times until the gap between the blade and the knife gate meets the shredding requirement. Therefore, the method for adjusting the gap between the knife gates in the prior art has long time consumption, low efficiency, and particularly low precision, and is difficult to effectively ensure the shredding quality of cigarettes.

The specific implementation mode is as follows:
the technical solution of the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.
When the method is implemented, the shredding width of the shredder is set, namely the gap between a blade and a knife gate meeting the shredding requirement of the shredder is set, and then the knife gate gap is adjusted according to the following operation steps.
When the method is adopted, a sensor is arranged on the filament cutter, as shown in figures 1 and 2, a first vibration sensor 12 is arranged on the diamond component 1, when the diamond 11 trims the grinding wheel 21, the first vibration sensor 12 can send out a signal and transmit the signal to a control system of the filament cutter; the knife gate 4 is provided with a second vibration sensor 41, when the blade 31 scratches the knife gate 41, the second vibration sensor 41 can send out a signal, and the signal is transmitted to a control system of the filament cutter; a visual recognition sensor 24 is arranged below the grinding wheel reciprocating device 22, and when the visual recognition sensor 24 detects that the grinding wheel 21 sharpens the spark generated by the blade 31 at any position in the full length range of the blade 31, the visual recognition sensor can send out a signal and transmit the signal to a control system of the filament cutter. After various signals are transmitted to the filament cutter control system, the filament cutter control system controls related execution devices to automatically complete the adjustment of the knife gate gap.
The flow of adjusting the knife gate gap by the method of the present invention is shown in fig. 3.
Firstly, the sharpening device 2 is started to sharpen the blade, the grinding wheel 21 sharpens the blade 31 in the full-length range, and when the visual recognition sensor 24 detects that the grinding wheel 21 sharpens all the blades 31 in the full-field range of the blade, a signal is sent out and is transmitted to the control system of the filament cutter. Thereupon sharpening of the blade 31 is stopped and the grinding wheel 21 is controlled to retract away from the blade 31.
When the grinding wheel 21 sharpens all the blades 31 in the full range of the blades, the cutting edge of the blade 31 is kept sharp, and all the blades rotate to form a cutting revolving body with a certain diameter, wherein the certain diameter is the diameter which ensures that all the blades are on the same circumference of the knife roller 3, and after all the blades 31 are on the same circumference of the knife roller 3, the lengths of all the blades 31 are consistent, so that the lengths of all the cut tobaccos during shredding can be ensured to be equal.
And controlling the grinding wheel 21 to move out of the full-length range of the blade, specifically, operating the grinding wheel feeding device 23 to lift the grinding wheel 21, simultaneously moving the grinding wheel 21 out of the full-length range of the blade by the grinding wheel reciprocating device 22, and stopping the blade grinding of the blade 31 by the blade grinding device.
The feed device 32 is then activated. The operation of the feed device 32 causes the blade 31 to continuously extend to approach the knife gate 4, and at this time, the cutting rotary diameter which can be formed when the blade 31 rotates is increased until the extended blade 31 scratches the knife gate 4. At this time, the second vibration sensor 41 sends a signal to the shredder control system, and the shredder control system control program determines that the gap between the blade 31 and the knife gate 4 is 0, and stops the feeding. This operation determines the position of the blade 31.
Then, the grinding wheel reciprocating device 22 is activated, the grinding wheel reciprocating device 22 moves the grinding wheel 21 to the middle of the length direction of the blade, that is, the middle of the knife roll 3, the grinding wheel feeding device 23 is activated to lower the height of the grinding wheel 21, and the grinding wheel 21 approaches the blade 31. When the grinding wheel 21 is again sharpened to all the blades 31 over the full length of the blade, the visual recognition sensor 24 sends a signal to the shredder control system. At this time, the shredder control system determines that the gap between the grindstone 21 and the blade 31 is 0, and then stops the feed of the grindstone 21.
After stopping the feeding of the grinding wheel 21, the grinding wheel reciprocating device 22 is started to move the grinding wheel 21 to be right above the diamond 11, and then the diamond assembly 1 is started, and the diamond feeding device 13 raises the diamond 11 to be close to the grinding wheel 21. When the diamond 11 comes into contact with the grinding wheel 21, the first vibration sensor 12 sends a signal and transmits the signal to the shredder control system. At this time, the filament cutter control system considers that the gap between the grinding wheel 21 and the diamond 11 is 0, and then stops the feeding of the diamond 11. The filament cutter control system memorizes the position of the diamond 11 at this time and takes this position as a reference position.
After the diamond reference position is determined, the diamond feeding device 13 reduces the height of the diamond 11, and the reduced height is the set gap value between the blade and the knife gate which meets the shredding requirement of the shredder.
Finally, the sharpening device 2 is started to sharpen, and after a period of sharpening, the diameter of the cutting revolution formed when the blade 31 rotates is reduced, and the position of the grinding wheel 21 is lowered until the diamond 11 contacts the grinding wheel 21. At this point, the first vibration sensor 12 sends a signal to the shredder control system to stop sharpening the knives.
Through these steps, the positional relationship between the blade 31 and the tool gate 4, the grinding wheel 21 and the diamond 11, and the blade 31 and the grinding wheel 21 is determined, and the value of the blade-tool gate gap is determined, and the whole tool gate gap adjusting process is completed. The gap between the blade 31 and the knife gate 41 is the set gap value between the blade and the knife gate which meets the shredding requirement of the shredder.
In other embodiments, diamond assembly 1 is activated to cause its diamond 11 to dress the grinding wheel 21 while the grinding wheel 21 is initially sharpening all blades 31 over the full range of the blades. The purpose of the diamond 11 dressing the grinding wheel 21 is to ensure the correct position of the grinding wheel 21 in such a way as to ensure that the diameter of the cutting revolution formed when the grinding wheel 21 sharpens the blade 31 is constant at any time.
In other embodiments, the first vibration sensor 12 and the second vibration sensor 41 may be velocity vibration sensors or acceleration vibration sensors or other devices capable of detecting the occurrence of a rub between objects, which signals when the objects vibrate.
In other embodiments, the visual recognition sensor 24 is a camera or spark detector or other device capable of recognizing a spark that signals when the object is sparking.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
