Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cigarette making machines, in particular to a debugging device for a shearing-type paper cutter and a cigarette making machine unit. Background Art
[0002] Tipping paper is processed by the cigarette making unit. A paper cutter and a paper cutting wheel are installed in the cigarette making machine. A paper cutter is installed circumferentially on the knife roller, and a paper cutting groove is formed circumferentially on the paper cutting wheel. The long strips of tipping paper are adsorbed by the paper cutting wheel and then cut by the paper cutter. The tipping paper is cut into fixed lengths and finally transported to the integrated wheel for wrapping.
[0003] However, during the installation of the paper cutter, it is necessary to adjust the distance between the blade on the knife roller and the paper cutting groove. If the distance between the paper cutter and the paper cutting groove is too large, the pressure formed between the paper cutter and the paper cutting groove will be too light, resulting in the inability to cut the kraft paper, affecting the production quality. If the distance between the paper cutter and the paper cutting groove is too small, the pressure between the paper cutter and the paper cutting groove will be too heavy, and the paper cutter is prone to breakage, shortening the working life of the paper cutter and affecting the cigarette machinery and cigarette production quality. In addition, since the degree of wear of each paper cutter and the paper cutting groove is inconsistent, and there is a gear gap, it is relatively difficult to adjust the pressure to the optimal state. It is time-consuming. Under the prior art, the distance adjustment between the paper cutter and the paper cutting slot needs to rely on experience and intuition. At the same time, under the prior art, the worker directly moves the end plate on the knife roller by hand to move the knife roller relative to the rotating shaft inside the knife roller. The manual movement has a large error, and usually requires repeated alignment and adjustment to adapt the distance between the paper cutter and the paper cutting slot, resulting in a long time. If there is insufficient experience, the distance between the paper cutter and the paper cutting slot often exceeds the target value, resulting in the paper cutter being unable to reach the optimal distance with the paper cutting slot, resulting in the inability to cut the tipping paper or the paper cutter breaking, thereby reducing production efficiency. Utility Model Content
[0004] The utility model aims to provide a debugging device for a shearing-type paper cutter and a cigarette making machine unit, so as to solve the problem that the adjustment of the spacing between the paper cutter and the paper cutting groove in the prior art takes a long time and has a large error.
[0005] To achieve this purpose, the utility model adopts the following technical scheme: the utility model provides a debugging device for a shear-type paper cutter, comprising a first fixing member, a second fixing member and an adjusting screw, wherein a first adjusting nut is installed in the first fixing member, the first fixing member is installed on the rotating shaft of the cigarette making unit, a second adjusting nut is installed in the second fixing member, the second fixing member is installed on the end plate and the knife roller of the cigarette making unit, and the adjusting screw passes through the second adjusting nut and is screwed into the first adjusting nut; when the adjusting screw rotates clockwise, the second fixing member approaches the first fixing member, and when the adjusting screw rotates counterclockwise, the second fixing member moves away from the first fixing member.
[0006] Preferably, a first spherical bearing is installed in the first fixing member, and a first adjusting nut is installed at the center of the first spherical bearing.
[0007] Preferably, a second spherical bearing is installed in the second fixing member, and a second adjusting nut is installed at the center of the second spherical bearing.

The distance between the paper cutter and the paper cutting slot can be accurately moved closer or farther away by rotating the adjusting screw. At the same time, by controlling the rotation angle of the adjusting screw, the distance between the paper cutter and the paper cutting slot can be flexibly adjusted, so that the adjustment result is more accurate, the adjustment threshold is lowered, the adjustment time is shortened, and the production efficiency is improved.

DETAILED DESCRIPTION
[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.
[0017] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0018] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0019] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0020] Under the existing technology, the end plate and the knife roller are directly moved manually. Since the adjustment range is very small, the error of manual movement alone is large, which often causes the distance between the paper cutter and the paper cutting slot to be too large or too small, requiring workers to repeatedly make corrections and adjustments, which reduces production efficiency.
[0021] In order to solve the above problems, Figure 1 to Figure 2 As shown, the utility model provides a debugging device for a shear-type paper cutter, comprising a first fixing member 1, a second fixing member 2 and an adjusting screw 30, wherein a first adjusting nut is installed in the first fixing member 1, the first fixing member 1 is installed on the rotating shaft of the cigarette making unit, a second adjusting nut is installed in the second fixing member 2, the second fixing member 2 is installed on the end plate 8 and the knife roller 9 of the cigarette making unit, and the adjusting screw 30 passes through the second adjusting nut and is screwed into the first adjusting nut; when the adjusting screw 30 rotates clockwise, the second fixing member 2 approaches the first fixing member 1, and when the adjusting screw 30 rotates counterclockwise, the second fixing member 2 moves away from the first fixing member 1.
[0022] The thread of the adjusting screw 30 of the utility model is M5, that is, one rotation advances 0.5mm, that is, when the adjusting screw 30 is rotated clockwise, the second fixing member 2 approaches the first fixing member 1 by 0.5mm. Since the first fixing member 1 is fixed on the rotating shaft, the position of the first fixing member 1 will not change, and since the knife roller 9 is fixed on the end plate 8, the knife roller 9 will drive the paper cutter 91 to move 0.5mm toward one side of the first fixing member 1 along the length direction of the adjusting screw 30, that is, 0.5mm closer to one side of the cutting groove 71. Conversely, when the adjusting screw 30 is rotated counterclockwise, the paper cutter 91 will move away from the cutting groove 71. The adjusting screw 30 can be used to achieve fine adjustment of the distance between the paper cutter 91 and the cutting groove 71, thereby reducing the error of manual adjustment.
[0023] The adjusting screw 30 of the utility model is equipped with a circular dial, and a 360° scale is formed on the circumference of the dial. When the dial is rotated 1°, the distance between the paper cutter 91 and the cutting groove 71 will change by 0.0013mm, and the cutting pressure generated by the paper cutter 91 can be finely adjusted. The accuracy of the above adjustment method is higher than that of manually adjusting the distance between the paper cutter 91 and the cutting groove 71, so the adjustment accuracy is improved, the number of repeated adjustments is reduced, the adjustment time is shortened, and the learning threshold is lowered.
[0024] A first joint bearing 11 is installed in the first fixing member 1, and a first adjusting nut is installed at the center of the first joint bearing 11. A second joint bearing 21 is installed in the second fixing member 2, and a second adjusting nut is installed at the center of the second joint bearing 21.
[0025] The outer surfaces of the first joint bearing 11 and the second joint bearing 21 are spherical, and the first joint bearing 11 and the second joint bearing 21 can rotate freely in the first fixing member 1 and the second fixing member 2. In the process of adjusting the position of the knife roller 9, the first joint bearing 11 and the second joint bearing 21 can be rotated to avoid the occurrence of limiting phenomenon, so that the adjusting screw 30 will not get stuck during the rotation process, and the degree of freedom is higher.
[0026] A first threaded sleeve 3 is installed at the lower end of the first fixing member 1, and a thread is formed on the inner side of the first threaded sleeve 3. A thread is formed on the lower end of the first fixing member 1. The first stud 5 and the first fixing member 1 are screwed on both ends of the first threaded sleeve 3 respectively. The first stud 5 is screwed in the rotating shaft. The first fixing member 1 and the first stud 5 are connected through the first threaded sleeve 3, which can lengthen the fixing height of the first fixing member 1 so that its height can be on the same horizontal plane as the second fixing member 2, so that the adjusting screw 30 is simultaneously inserted into the first fixing member 1 and the second fixing member 2. The length of the first stud 5 can be flexibly replaced, so that the adjustment device of the utility model has stronger adaptability.
[0027] The second fixing member 2 is provided with a second threaded sleeve 4 at the lower end thereof, the inner side of the second threaded sleeve 4 is provided with a thread, the lower end of the second fixing member 2 is provided with a thread, the two ends of the second threaded sleeve 4 are respectively screwed with a second stud 6 and the second fixing member 2, and the second stud 6 is screwed in the end plate 8 and the knife roller 9. The second stud 6 can be replaced by the same arrangement, so that the height of the second fixing member 2 and the first fixing member 1 are flush, which is convenient for adjusting the screw rod 30 for connection and avoiding the phenomenon of position limitation.
[0028] The first fixing part 1 is a GA8-DO spherical bearing, and the second fixing part 2 is a BNM-6 spherical bearing. The use of standard parts can reduce the manufacturing cost of the debugging device and facilitate procurement. Fixing nuts 20 are installed at both ends of the first threaded sleeve 3 and the second threaded sleeve 4, so that the two ends of the first threaded sleeve 3 and the two ends of the second threaded sleeve 4 are connected more stably without shaking.
[0029] A cigarette making unit includes a rotating shaft and a paper cutting wheel 7. A knife roller 9 is sleeved on the rotating shaft. The rotating shaft drives the knife roller 9 to rotate. Under normal working conditions, the rotating shaft drives the knife roller 9 on the end plate 8 to rotate. A gap is formed between the knife roller 9 and the rotating shaft, so the end plate 8 can drive the knife roller 9 to move and adjust the distance between the paper cutter 91 and the knife groove 71. Three groups of first through holes and three groups of second through holes are formed on the circumference of the end plate 8. The first bolt 40 passes through the first through hole and is screwed on the rotating shaft. The second bolt 50 passes through the second through hole and is screwed on the knife roller 9. The first bolt 40 and the second bolt 50 are alternately distributed on the circumference of the end plate 8.
[0030] When it is necessary to adjust the distance between the paper cutter 91 and the cutting groove 71, it is necessary to remove any adjacent first bolts 40 and second bolts 50, and loosen the remaining two groups of first bolts 40, screw the first fixing member 1 into the screw hole of the removed first bolt 40, and screw the second fixing member 2 into the screw hole of the removed second bolt 50, so that the first fixing member 1 is close to one side of the paper cutting wheel 7 and the adjusting screw 30 is kept horizontal, the second fixing member 2 passes through the end plate 8 and is screwed onto the knife roller 9, the first fixing member 1 passes through the end plate 8 and is screwed onto the rotating shaft, the knife roller 9 is circumferentially installed with a paper cutter 91, a cutting groove 71 is formed on the paper cutting wheel 7, the paper cutter 91 is inserted into the cutting groove 71, and the paper cutter 91 cuts the kraft paper attached to the cutting groove 71.
[0031] The second stud 6 on the second fixing member 2 is equipped with a locking nut 10, which can abut against the end plate 8 to fasten the second fixing member 2 and the end plate 8. During the adjustment process, the position of the first fixing member 1 relative to the paper cutting wheel 7 remains unchanged, and the second fixing member 2 drives the end plate 8 and the knife roller 9 on the end plate 8 to move along the axial direction of the adjusting screw 30, so that the cutting pressure can be finely adjusted. After the adjustment is completed, it is necessary to turn the wheel for one week to test the cutting of the tipping paper. If the cutting pressure is not appropriate and there are still places where the tipping paper cannot be cut, repeat the above process until the paper cutter 91 runs for one week and all the tipping papers can be cut at the cutting position.
[0032] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
