[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] like Figure 1-Figure 16 As shown, an embodiment of the present application provides a cutting device for a cigarette rolling machine, which is used in a cigarette rolling machine group of a cigarette production line, specifically for cutting cigarettes. The cigarette cutting equipment used in the past includes a knife disc and a blade. The knife disc is in the shape of a disc, and the blade is arranged on the outer peripheral edge of the knife disc. The rotation of the knife disc drives the blade to cut the cigarette. Under the condition of high-intensity cutting of cigarettes by the blade, the blade needs to be replaced regularly. Since the blade and the knife disc are usually connected by a fixed connection such as welding or by a plurality of screws, it is very inconvenient and time-consuming to replace the blade, which results in a long downtime of the cigarette rolling machine group, affecting the production efficiency of the cigarette rolling machine group. The cutting device for the cigarette rolling machine of the present application aims to improve the convenience of replacing the blade, reduce the time-consuming replacement process, avoid excessive downtime of the cigarette rolling machine group, and improve production efficiency.

[0038] Specifically, the cutting device of the curling machine provided by the present application includes a knife disc 1, a mounting seat 11, a connecting assembly and a blade 2, and also includes a driving device 3 and a driving shaft 4. The knife disc 1 is disc-shaped and has an axis. One end of the driving shaft 4 is coaxially connected to the middle of the knife disc 1, and the other end of the driving shaft 4 is connected to the output end of the driving device 3. Under the drive of the driving device 3, the knife disc 1 rotates circumferentially around its own axis. A mounting cavity 101 is formed inside the knife disc 1, and a through groove 1201 is formed on the circumferential outer side of the knife disc 1. The opening direction of the through groove 1201 opens outward along the radial direction of the knife disc 1, and the outer end opening of the through groove 1201 is radially outward. The inner end opening of the through groove 1201 is connected to the mounting cavity 101. The mounting seat 11 is arranged inside the mounting cavity 101, and the blade 2 is arranged in a long strip shape. The inner end of the blade 2 extends to the inside of the mounting cavity 101, and the outer end of the blade 2 extends out of the through groove 1 along the radial direction of the knife disc 1. 201, when the cutter disc 1 drives the blade 2 to rotate, the rotation radius of the outer edge of the blade 2 is greater than the radius of the cutter disc 1, so that the blade 2 can rotate to cut the cigarette, and the connecting component is arranged in the mounting cavity 101. Under the action of the connecting component, the blade 2 and the mounting seat 11 can be detachably connected, thereby limiting the blade 2 from escaping from the through-groove 1201. The through-groove 1201 limits the blade 2 in the direction other than the radial direction, and the connecting component detachably connects the blade 2 and the mounting seat 11 to achieve a stable installation of the blade 2. After the connecting component and the blade 2 are disengaged, the blade 2 can radially outwardly escape from the through-groove 1201, and the disassembly is also convenient. The new blade 2 is penetrated from the outside to the inside into the through-groove 1201, and then the blade 2 is connected to the mounting seat 11 under the action of the connecting component, which can greatly increase the convenience of replacing the blade 2, help to reduce the time for replacing the blade 2, avoid long-term equipment shutdown, and prevent adverse effects on production efficiency.

[0039] Specifically, a mounting groove 1101 is provided on the mounting seat 11, and the mounting groove 1101 is used to install the blade 2. The mounting groove 1101 is recessed on one side of the mounting seat 11, and the opening direction of the mounting groove 1101 is radially outward. The blade 2 can extend into the mounting groove 1101 after passing through the through groove 1201, and then under the action of the connecting component, the blade 2 and the mounting seat 11 are detachably connected to improve the connection stability between the blade 2 and the mounting seat 11.

[0040] In this embodiment, the connecting component can specifically include a holding portion 51 and a matching portion, and the holding portion 51 and the matching portion are connected to each other. The matching portion can extend into the mounting groove 1101 on one side of the mounting seat 11 and realize a snap-fitting fit with the blade 2, thereby realizing the connection between the blade 2 and the mounting seat 11. At least part of the holding portion 51 extends out of the blade disc 1, and the connecting component can be controlled by the holding portion 51 to connect or disconnect the blade 2 and the mounting seat 11 to each other, so as to replace the blade 2.

[0041] More specifically, the mating portion includes a base 521, on which a plurality of limiting rods 522 are arranged, a first through hole 61 penetrating into the mounting groove 1101 is arranged on one side of the mounting seat 11, a second through hole 62 is arranged on the blade 2, and the second through hole 62 is arranged at the inner end of the blade 2, the inner end of the blade 2 provided with the second through hole 62 can enter into the mounting groove 1101, and after the inner end of the blade 2 enters into the mounting groove 1101, the first through hole 61 and the second through hole 62 can be axially aligned, the limiting rod 522 can penetrate the first through hole 61 and the second through hole 62 to connect the blade 2 with the mounting groove 1101, and then the first through hole 61 and the second through hole 62 are pulled out through the limiting rod 522. The hole 62 or the limiting rod 522 is inserted into the first through hole 61 and the second through hole 62 to realize the mutual disengagement or mutual connection between the blade 2 and the mounting seat 11. The connection method is simple. The limiting rod 522 can be operated through the holding portion 51, which greatly improves the convenience of mutual connection and disengagement between the blade 2 and the mounting seat 11, and facilitates the replacement of the blade 2. By pulling the holding portion 51 outward, the limiting rod 522 is pulled out of the first through hole 61 and the second through hole 62, and the blade 2 and the mounting seat 11 can be disengaged. Pushing the holding portion 51 inward can make the limiting rod 522 enter the first through hole 61 and the second through hole 62, and the blade 2 and the mounting seat 11 are connected together.

[0042] Specifically, the number of the limiting rods 522 is the same as the number of the first through holes 61 , the number of the second through holes 62 , and the number of the blind holes 63 .

[0043] In this embodiment, an elastic member 7 can be arranged between the holding portion 51 and the blade disc 1. The elastic member 7 can push the holding portion 51 inward, thereby driving the limiting rod 522 to enter the first through hole 61 and the second through hole 62, so that the limiting rod 522 remains in the first through hole 61 and the second through hole 62, thereby improving the reliability of the connection between the blade 2 and the mounting seat 11, preventing the limiting rod 522 from accidentally falling out of the first through hole 61 and the second through hole 62 when the blade disc 1 rotates at high speed, and preventing the blade 2 from accidentally detaching.

[0044] Specifically, the holding portion 51 is in the shape of a round rod, and a handle 511 is provided at the outermost end of the holding portion 51. The outer size of the handle 511 is larger than the outer size of the holding portion 51. The elastic member 7 is a spring, and the spring is sleeved on the holding portion 51. One end of the spring is connected to the handle 511, and the other end of the spring is connected to the outer side of the blade disc 1. The spring is in a stretched state, and can maintain a state of pushing the holding portion 51 inward, so that the limiting rod 522 remains in the first through hole 61 and the second through hole 62.

[0045] In this embodiment, the limiting rod 522 is also in the shape of a round rod, the length direction of the holding portion 51 is parallel to the length direction of the limiting rod 522 and is parallel to the axis direction of the cutter disc 1 itself, the base 521 has a certain length, the holding portion 51 and the base 521 are vertically arranged, the limiting rod 522 and the base 521 are vertically arranged, the axis directions of the first through hole 61 and the second through hole 62 are parallel to the axis direction of the cutter disc 1 itself, the holding portion 51 axially extends out of the mounting cavity 101, a part of the holding portion 51 is in the mounting cavity 101, and the other part of the holding portion 51 is outside the mounting cavity 101, The hand 511 is arranged at the outer end of the holding portion 51, one end of the spring is connected to the handle 511, and the other end of the spring is connected to the axial side of the blade 2. In this way, the movement direction of the holding portion 51, the base 521 and the limiting rod 522 is the axial direction of the blade disc 1, which is perpendicular to the rotation direction of the blade disc 1, thereby greatly improving the stability of the limiting rod 522 relative to the first through hole 61 and the second through hole 62 during the rotation process, and can prevent the limiting rod 522 from accidentally falling out of the first through hole 61 and the second through hole 62, thereby further improving the stability and reliability of the mutual connection between the blade 2 and the blade disc 1.

[0046] More specifically, the installation cavity 101 is circumferentially arranged on the cutter disc 1 around the axis of the cutter disc 1 itself, and the opening of the installation cavity 101 faces one side of the axial direction, that is, the installation cavity 101 is a coaxial recessed structure formed on the cutter disc 1, and under the action of the installation cavity 101, the cutter disc 1 is formed into an inner ring portion 13 and an outer ring portion 12. The inner ring portion 13 and the outer ring portion 12 are coaxial, and the outer ring portion 12 surrounds the outside of the installation cavity 101, and the installation cavity 101 surrounds the outside of the inner ring portion 13. A through groove 1201 is formed on the outer ring portion 12, and the through groove 1201 penetrates the outer ring portion 12 along the radial direction of the cutter disc 1, and the through groove 1201 is connected with the installation cavity 101, so that the blade 2 can be inserted into the installation cavity 101 through the through groove 1201.

[0047] Specifically, the blade 2 can be one or more. When multiple blades 2 are provided, the speed of cutting cigarettes can be improved. The number of blades 2, connecting components and mounting seats 11 corresponds, that is, the number of the three is the same. When multiple blades 2 are provided, each mounting seat 11 is symmetrically arranged in the mounting cavity 101 relative to the axis of the cutter disc 1, so that the multiple blades 2 are also centrally symmetrically arranged relative to the axis of the cutter disc 1, so that cigarettes can be cut at a uniform speed.

[0048] More specifically, the first through hole 61 passes through one side of the mounting seat 11 to one side of the mounting groove 1101, and a blind hole 63 can be set on the other side of the mounting groove 1101. The blind hole 63 and the first through hole 61 are coaxial, and the end of the limiting rod 522 can enter the blind hole 63. When the blade 2 is connected, the end of the blade 2 with the second through hole 62 extends into the mounting groove 1101, and the limiting rod 522 passes through the first through hole 61 and the second through hole 62 in turn and pushes into the blind hole 63, which can greatly increase the limiting strength of the limiting rod 522 on the blade 2 and improve the stability of the connection.

[0049] In this embodiment, the mounting cavity 101 is formed as an open cavity surrounded by three sides, and the base 521 falls on the side surface of the mounting cavity 101 that is closest to the center of the cutter disc 1. The side surface is a curved surface surrounding the axis of the cutter disc 1. The base 521 can move along the axial direction of the cutter disc 1 on the side surface, and the length direction of the base 521 is tangent to the circumferential direction of the cutter disc 1. A plurality of limit rods 522 are evenly and spacedly arranged along the length direction of the base 521. One end of the holding portion 51 is connected to the base 521, and the other end of the holding portion 51 extends to one side of the cutter disc 1. By holding the holding portion 51 on the outer side of the cutter disc 1 and pulling the holding portion 51 axially outward, the limit rod 522 is driven to move axially through the base, so that the limit rod 522 is pulled out of the blind hole 63, the second through hole 62 and the first through hole 61, so that the blade 2 and the mounting seat 11 can be separated from each other, and the holding portion 51 is pushed in the opposite direction along the axis. Then, the limiting rod 522 can pass through the first through hole 61 and the second through hole 62 and enter into the blind hole 63, so as to realize the mutual connection between the blade 2 and the mounting seat 11. At this point, when the connecting component is in the first state, that is, the limiting rod 522 passes through the first through hole 61, the second through hole 62 and the blind hole 63, so that the blade 2 and the mounting seat 11 remain connected. When the connecting component is in the second state, that is, the limiting rod 522 escapes from the blind hole 63, the second through hole 62 and the first through hole 61, so that the blade 2 can be separated from the mounting seat 11. In this way, the connecting component can be conveniently converted between the first state and the second state through the holding portion 51 on the outside of the blade disc 1, so as to realize the installation and disassembly of the blade 2 on the blade disc 1. The operation is very convenient, which can greatly reduce the time for replacing the blade 2, thereby helping to reduce the downtime of the winding and splicing unit and avoid adverse effects on the production efficiency of the winding and splicing unit.

[0050] In this embodiment, a step 14 is correspondingly provided on the side of the cutter disc 1 for the position where the holding portion 51 on the cutter disc 1 extends out, and the step 14 protrudes a certain height from the cutter disc 1. An axial through hole is provided at the position on the cutter disc 1 corresponding to the step 14, and a through hole is also provided on the step 14 for the holding portion 51 to pass through. The holding portion 51 passes outward from the step 14, which can increase the sliding fit length between the holding portion 51 and the cutter disc 1 to a certain extent, and improve the stability of the holding portion 51 during operation. A spring sleeve is provided on the holding portion 51, one end of the spring is connected to the handle 511, and the other end of the spring is connected to the step 14, so that the spring is in a stretched state. Therefore, in a natural state, under the tension of the spring, the holding portion 51 has the tendency to move toward one side of the mounting cavity 101. The limit rod 522 is driven by the base to move toward the mounting seat 11, so that the limit rod 522 remains in the first through hole 61, the second through hole 62 and the blind hole 63, so that the connecting assembly is in the first state, that is, the blade 2 is connected to the cutter disc 1. When the blade 2 needs to be removed, the operator holds the handle 511 and pulls the holding portion 51 outward along the axial direction, and then drives the limit rod 522 through the base to move in the direction away from the mounting seat 11, so that the limit rod 522 escapes from the blind hole 63, the second through hole 62 and the first through hole 61. At this time, it is the second state of the connecting assembly, and then the blade 2 can be removed from the mounting groove 1101, and the blade 2 is pulled radially outward from the through groove 1201 as a whole, thus completing the removal of the blade 2.

[0051] In this embodiment, a fixed seat 8 can also be included, and a driving shaft 4 is arranged between the driving device 3 and the cutter disc 1, one end of the driving shaft 4 is coaxially connected to the cutter disc 1, and the other end of the driving shaft 4 is connected to the output end of the driving device 3. At that time, the driving device 3 is installed on the fixed seat 8, and a fixing platform 81 is arranged on the fixed seat 8. The fixing platform 81 is a hollow cylindrical structure. Correspondingly, a hole coaxial with the hollow structure of the fixing platform 81 is arranged on the fixed seat 8, so that the driving shaft 4 can pass through and be connected with the driving device 3 on the fixed seat 8. A wear-resistant sleeve can be arranged between the fixing platform 81 and the driving shaft 4, and a bearing can be arranged between the wear-resistant sleeve and the driving shaft 4. The inner side wall of the wear-resistant sleeve can also be made of wear-resistant material. The wear-resistant sleeve includes two symmetrically arranged half sleeves 91. The two half sleeves 91 form a cylindrical structure after being butted together. A flange half ring 92 is arranged at one end of the half sleeve 91. After the two half sleeves 91 are butted together into a cylindrical body, the two flange half rings 92 are also butted together into a whole flange so as to be connected to the fixed platform 81. For the joint surfaces where the two half sleeves 91 are butted together, a positioning column 911 is arranged on one of the two half sleeves 91, and a positioning hole 912 is arranged on the other of the two half sleeves 91. When the two half sleeves 91 are butted together, the positioning column 911 can be adapted to be engaged in the positioning hole 912, which facilitates the butting and joining of the two half sleeves 91 and can also increase the stability of the connection between the two half sleeves 91.

[0052] In addition, it should be noted that the mounting seat 11 and the blade disc 1 can be connected by welding, and the handle 511 and the holding portion 51 can be connected by threads. During actual assembly, the holding portion 51 can first be passed through the blade disc 1 from the mounting cavity 101 to the other side, and then the elastic member 7 and the handle 511 can be installed, and then the mounting seat 11 can be welded in the mounting cavity 101, as long as the installation of each component is convenient.

[0053] The working principle of the present application is as follows: the cigarette making machine cutting device is installed on the cigarette making machine group through the fixing seat 8, so that when the cutter disc 1 rotates, the blade 2 on the cutter disc 1 can cut the cigarette. When the blade 2 needs to be replaced, the machine is shut down first. After the equipment stops running, the operator pulls the handle 511 outward. When the force is greater than the force of the elastic member 7 on the holding portion 51, the holding portion 51 moves along the axial direction and in the direction away from the mounting seat 11, and then drives the limiting rod 522 to move through the base 521, so that the limiting rod 522 disengages from the blind hole 63, the second through hole 62 and the first through hole 61. The connecting component is in the second state at this time. In this state, the blade 2 is pulled radially outward until the blade 2 disengages from the mounting groove 1101. And through-slot 1201, then the new blade 2 is passed through the through-slot 1201 again and partially enters into the mounting slot 1101, so that the second through hole 62 on the blade 2 is coaxial with the first through hole 61 on the mounting seat 11. At this time, the operator releases the handle 511 on the holding portion 51, and under the elastic force of the elastic member 7, the holding portion 51 moves in the opposite direction, so that the limiting rod 522 passes through the first through hole 61 and the second through hole 62 in turn and presses into the blind hole 63. At this time, it is the first state of the connecting component, and the installation of the new blade 2 is completed. The blade 2 is replaced very conveniently every day, which can greatly reduce the time for replacing the blade 2, reduce the downtime of the winding and splicing unit as much as possible, and avoid excessive impact on the production efficiency of the winding and splicing unit.

[0055] It should be easily understood that “on,” “above,” and “over” in the present disclosure should be interpreted in the broadest manner, so that “on” not only means “directly on something,” but also includes the meaning of “on something” with intervening features or layers therebetween, and “above” or “over” not only includes the meaning of “above” or “over,” but also may include the meaning of “above” or “over something” with no intervening features or layers therebetween (i.e., directly on something).

[0056] In addition, spatially relative terms, such as "below," "below," "beneath," "above," "above," etc., may be used herein for ease of description to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. The device may have other orientations (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein may likewise be interpreted accordingly.

[0057] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
