Description

Technical Field

[0001] The present application relates to the technical field of tobacco shred recovery, and in particular to a fence-type rake-nail breaking and rupturing device for cigarettes. Background Art

[0002] In the process of producing cigarettes, cigarette factories often produce defective cigarettes. In order to avoid waste, cigarette factories usually recycle the tobacco in the defective cigarettes. During the recycling process, the cigarettes must first be broken and cracked, and then the broken and cracked cigarettes must be screened. The tobacco can be separated after screening, and then the cigarette paper, filter and other debris are collected and processed. Breaking and cracking defective cigarettes has always been a process explored by cigarette factories. At present, the more commonly used treatment method is to crush the defective cigarettes through a circular screening cylinder. However, the treatment method of the circular screening cylinder has certain disadvantages. For example, the degree of crushing of the cigarettes is not easy to control. If the degree of crushing of the cigarettes is increased by increasing the rotation speed of the circular screening cylinder, the crushing effect of the cigarettes is better, and the tobacco is more likely to be crushed during subsequent screening. It can also be separated very well, but the increase in the degree of crushing leads to a deeper degree of crushing of the cigarette paper and the filter, resulting in more cigarette paper fragments and filter fiber fragments, causing the amount of debris in the tobacco to increase, and reducing the purity of the recycled tobacco. If the purity of the tobacco is to be improved, the rotation speed of the circular screening cylinder must be reduced, and the degree of crushing of the cigarettes must be reduced to avoid the generation of cigarette paper fragments and filter fiber fragments. However, the reduction in the degree of crushing of the cigarettes makes the degree of crushing of the cigarettes insufficient, and the tobacco wrapped in the cigarette paper is not easy to separate, and the separation effect of the tobacco is poor during subsequent screening. Therefore, when using the circular screening cylinder to recycle the tobacco from the defective cigarettes, it is faced with the choice and abandonment among multiple indicators such as the purity of the tobacco and the separation effect of the tobacco. Therefore, there are deficiencies in the recycling of defective cigarettes at this stage. Utility Model Content

[0032] 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.

[0033] like Figure 1-Figure 7 As shown, the embodiment of the present application provides a fence-type rake-nail breaking and rupturing device for cigarettes, which is used in the process of recycling and processing defective cigarettes, specifically breaking and rupturing the cigarettes so as to separate the tobacco and cigarette paper during subsequent screening. In the past, when recycling defective cigarettes, circular screening cylinders were mostly used. However, the circular screening cylinders cannot take into account multiple indicators of the recycling of defective cigarettes during application, such as the purity of the recycled tobacco and the separation effect of the tobacco. In order to improve the separation effect between the tobacco and the cigarette paper during screening, the rotation speed of the circular screening cylinder must be increased to increase the degree of destruction of the defective cigarettes. After the degree of destruction of the cigarettes is improved, it is more conducive to the subsequent screening of the tobacco and the cigarette paper. The separation between the cigarette papers and the filter tip is caused by the increased degree of damage to the cigarettes, and the increase in the degree of damage to the cigarettes makes the cigarette papers and the filters excessively broken, which easily produces more shredded paper and filter tip debris, and the purity of the separated tobacco after screening is affected. If the purity of the tobacco is to be improved, the rotation speed of the circular screening cylinder needs to be reduced to reduce the degree of damage to the cigarettes. Correspondingly, the insufficient degree of damage to the cigarettes makes it difficult for the tobacco to be separated from the cigarette papers in the subsequent screening. Therefore, the process method of the circular screening cylinder has certain shortcomings. The fence-type rake nail breaking and rupture device for cigarettes provided in the present application is intended to improve the processing effect of defective cigarettes. When the processed cigarettes are screened, the tobacco and cigarette paper are easier to separate and the purity of the separated tobacco is improved.

[0034] Specifically, the fence-type rake-nail breaking and rupturing device for cigarettes comprises a cigarette channel 100, a fence assembly 2, a rotating assembly 3 and a driving device 4. In this embodiment, the cigarette channel 100 can be an overall groove-shaped structure and has a certain length, and cigarettes can be moved and transported in the cigarette channel 100. The fence assembly 2 has a certain length. The fence assembly 2 spans the cigarette channel 100 along its own direction. The two ends of the fence assembly 2 are respectively arranged on both sides of the width direction of the cigarette channel 100. A plurality of windows 201 are arranged on the fence assembly 2 along the direction of the fence assembly 2 itself. The window 201 passes through both sides of the fence component 2. The rotating component 3 is rotatably installed on the cigarette channel 100. The rotating component 3 is arranged adjacent to the fence component 2. The rotating component 3 also has a certain length. The direction of the rotating component 3 is parallel to the direction of the fence component 2. The rotating component 3 also spans the cigarette channel 100 along its own length. The two ends of the rotating component 3 are rotatably installed on both sides of the width direction of the cigarette channel 100. A plurality of long arms 301 are arranged on the rotating component 3 along the direction of the rotating component 3. The positions of the plurality of long arms 301 are respectively and sequentially aligned with each other. The positions of the windows 201 on the plurality of fence components 2 are arranged correspondingly, that is, the number of the windows 201 is the same as the number of the long arms 301, one window 201 corresponds to one long arm 301, the driving device 4 is arranged on one side of the cigarette passage 100, the driving device 4 is connected to the rotating component 3, and driven by the driving device 4, the rotating shaft component is rotated around a virtual axis of itself. Specifically, the driving device 4 can be a driving motor, and the output shaft of the driving motor is connected to the rotating component 3, so as to drive the rotating component 3 to rotate. When the rotating component 3 rotates, each long arm 301 also Rotation occurs, so that each long arm 301 periodically passes through the corresponding window 201. When the long arm 301 passes through the window 201, the long arm 301 and the window 201 cooperate to break and rupture the cigarette. The cigarette in the cigarette channel 100 can be pushed forward manually. The specific conveying method will be further explained later. The cigarette moves forward in the cigarette channel 100. When the cigarette moves to the fence component 2 and is in front of the window 201, the rotating component 3 rotates, so that the long arm 301 periodically passes through the window 201, thereby breaking and rupturing the cigarette.

[0035] Specifically, when the rotating component 3 rotates, the long arm 301 periodically passes through the window 201. On the one hand, the long arm 301 and the fence component 2 cooperate to break and rupture the cigarette, and on the other hand, the long arm 301 also exerts a certain striking effect on the cigarette. The cigarette usually includes a filter segment and a tobacco segment. The tobacco segment is tobacco wrapped in cigarette paper, and the filter segment is filter fiber wrapped in corking paper. The toughness and strength of the filter segment are obviously higher than those of the tobacco segment. It is precisely relying on this characteristic that in the process of the long arm 301 and the window 201 cooperating to bend, break and rupture the cigarette, the tobacco segment is more easily broken and ruptured, and the long arm 301 and the window 201 cooperate only to break the tobacco segment. By setting the size of the window 201, the tobacco segment of the cigarette can be folded into several segments. In the subsequent screening, it is beneficial to the separation of tobacco and cigarette paper, and avoids the problem of low purity of recycled tobacco due to excessive damage to the cigarette.

[0036] Specifically, the fence assembly 2 includes a cross arm 202, which spans across the cigarette channel 100. A plurality of vertical arms 203 are arranged on the cross arm 202. One end of each vertical arm 203 is connected to the cross arm 202, and the other end of the vertical arm 203 extends downward toward the bottom of the cigarette channel 100. The plurality of vertical arms 203 are evenly spaced on the cross arm 202. The gap between two adjacent vertical arms 203 forms a window 201 of the fence assembly 2. The long arm 301 passes through the window 201, which means passing through the space between two adjacent vertical arms 203. The long arm 301 and the two adjacent vertical arms 203 cooperate with each other to break and rupture the cigarette. The top end of the vertical arm 203 is connected to the cross arm 202, and the bottom end of the vertical arm 203 extends downward. There is a preset gap between the bottom end of the vertical arm 203 and the bottom of the cigarette channel 100. The size of the preset gap can be adjusted according to the diameter of the cigarette to be processed, which will be described in detail later.

[0037] More specifically, the vertical arm 203 is arranged vertically, the cross arm 202 is in the shape of a long rod and is arranged horizontally, the vertical arm 203 is in the shape of a long rod and is arranged in the vertical direction, the vertical arm 203 and the cross arm 202 are arranged perpendicular to each other, the cross section of the vertical arm 203 is circular, and when the long arm 301 and two adjacent vertical arms 203 break the cigarette, the smooth outer surface of the vertical arm 203 is more conducive to the sliding and shifting of the cigarette, avoiding minor damage to the outer surface of the cigarette paper of the cigarette, and preventing the appearance of minor cigarette paper debris.

[0038] In this embodiment, a plurality of vertical arms 203 are arranged on the cross arm 202 in a single row along the direction of the cross arm 202 so as to evenly process the cigarettes.

[0039] More specifically, the rotating assembly 3 includes a rotating shaft 302, a plurality of long arms 301 are arranged along the axial direction of the rotating shaft 302 and connected to the rotating shaft 302, the rotating shaft 302 is horizontally arranged, the rotating shaft 302 can be rotatably installed on the cigarette passage 100, one end of the rotating shaft 302 is coaxially connected to the output shaft of the driving motor, so that the driving motor drives the rotating shaft 302 to rotate around the axis of the rotating shaft 302 itself, in the vertical direction, the height of the rotating shaft 302 is lower than the height of the cross arm 202, and the height of the rotating shaft 302 is within the height range of the vertical arm 203, when the rotating shaft 302 drives the long arm 301 to rotate, it can avoid the long arm 301 and the cross arm 202 from generating friction. Interference, specifically, each long arm 301 is perpendicular to the axis of the rotating shaft 302 and is connected to the rotating shaft 302, that is, the extension direction of the long arm 301 is the radial direction of the rotating shaft 302. When the rotating shaft 302 drives the long arms 301 to rotate, each long arm 301 rotates to perform a circular motion, and periodically and repeatedly passes through the gap between the corresponding two adjacent vertical arms 203. Each long arm 301 periodically passes through the space between two adjacent vertical arms 203, that is, when the rotating shaft 302 drives the multiple long arms 301 to rotate around the rotating shaft 302, the multiple long arms 301 periodically intersect and interpenetrate with the multiple vertical arms 203, resulting in the effect of breaking and rupturing the cigarette.

[0040] More specifically, the middle part of the long arm 301 is connected to the rotating shaft 302, and the diameter directions of the long arm 301 and the rotating shaft 302 coincide with each other, so that the two ends of the long arm 301 extend in different directions on both sides of the rotating shaft 302, so when the rotating shaft 302 drives the long arm 301 to rotate, one rotation can make each long arm 301 and the corresponding vertical arm 203 cooperate with each other twice, so that the cigarette is processed twice, which is beneficial to improve the processing efficiency of the cigarette. Specifically, the arrangement of each long arm 301 on the rotating shaft 302 can be a spiral arrangement. Preferably, the long arms 301 are arranged parallel to each other, so that the rotating component 3 is roughly in a row structure, and each vertical arm 203 is also roughly in a row structure. When rotating to process cigarettes, the cigarettes at each position can be broken and ruptured more evenly.

[0041] In this embodiment, a mounting hole 51 can be opened on the rotating shaft 302 corresponding to each long arm 301, and the mounting hole 51 penetrates the rotating shaft 302 along the diameter direction of the rotating shaft 302, and the long arm 301 can pass through the mounting hole 51. A threaded hole 52 is also provided on one side of the rotating shaft 302 at a position corresponding to each mounting hole 51, and the inner end of the threaded hole 52 is connected to the mounting hole 51, and the outer end of the threaded hole 52 is connected to the outside, so an anti-slip screw 53 can be provided in the threaded hole 52, and the anti-slip screw 53 is tightened so that the anti-slip screw 53 is pressed against the long arm 301 inserted into the mounting hole 51, so as to limit the long arm 301 from slipping out of the mounting hole 51, thereby realizing the connection between the middle part of the long arm 301 and the rotating shaft 302. In addition, in order to further increase the stability of the fixation of the long arm 301, a radial blind hole 54 can be provided on one side of the middle part of the long arm 301, and the anti-slip screw 53 is pressed against the blind hole 54 after passing through the threaded hole 52.

[0042] Specifically, the long arm 301 is also in the shape of a long strip, and the cross section of the long arm 301 is circular, so that the long arm 301 and the vertical arm 203 are both circular rods, which further avoids local damage to the cigarette paper and prevents the appearance of fine cigarette paper scraps.

[0043] In this embodiment, when the rotating shaft 302 drives the long arm 301 to rotate, there is also a preset gap between the bottom of the outer edge of the virtual circle of the rotation of the long arm 301 and the bottom of the cigarette channel 100, plus the preset gap between the bottom of the above-mentioned vertical arm 203 and the bottom of the cigarette channel 100. Preferably, the gap values ​​at the two locations are equal. When the equipment is specifically assembled, the gap values ​​at the two locations should be smaller than the diameter of the processed cigarette to prevent the cigarette from passing through the gap without damage, so that the long arm 301 and the vertical arm 203 can cooperate to smoothly break and rupture the cigarette.

[0044] More specifically, another factor that affects the breakage and rupture of cigarettes is the gap between the long arm 301 and the vertical arm 203 when the long arm 301 rotates. In other words, the cigarette channel 100 is rectangular, having a length and a width, and the cross arm 202 and the rotating shaft 302 are both arranged perpendicular to the length direction of the cigarette channel 100. In the projection along the length direction of the cigarette channel 100, the size of the gap between the adjacent long arms 301 and the vertical arms 203 affects the degree of breakage and rupture of the cigarettes. The transported cigarettes move from the cigarette channel 100 to the vertical arm 203 and stop, and the cigarettes and the cross arm 202 remain parallel. Within the length range of the cigarette, the more the number of vertical arms 203 and the number of long arms 301 that can be occupied, the more force points are generated on the cigarettes, and the greater the degree of breakage and rupture of the cigarettes.

[0045] More specifically, when the cigarettes are transported at the vertical arm 203, if the cigarettes are in a single-layer state and are moved to the vertical arm 203 in sequence and are hit and processed by the rotating long arm 301 in sequence, due to the gap between the bottom of the vertical arm 203 and the bottom of the cigarette channel 100 and the gap between the bottom of the rotating virtual circle of the long arm 301 and the cigarette channel 100, the destructive force point for the cigarettes is in a local area on the periphery of the cigarettes, and more importantly, the cigarette paper of the cigarettes is broken in multiple places to prevent the cigarettes from being excessively damaged, which is beneficial to improving the purity of the tobacco during subsequent screening. In addition, if the cigarettes are moved to the vertical arm 203 in a multi-layer arrangement state, under the blocking effect of the vertical arm 203, the cigarettes on the bottom layer are destroyed by the end of the long arm 301, and the cigarettes above are destroyed by the middle part of the long arm 301, so that the tobacco segments of the cigarettes are torn or broken. Under the premise of maintaining an appropriate degree of damage to the cigarettes, a large amount of paper scraps will not be generated.

[0046] Specifically, when the rotating shaft 302 drives the long arm 301 to rotate, the top of the rotating virtual circle of the long arm 301 does not interfere with the cross arm 202. More specifically, the setting position of the rotating shaft 302 is located on the side of the vertical arm 203 facing the cigarette, that is, after the cigarette moves to the front of the vertical arm 203 and stops, the stopped cigarette and the rotating shaft 302 are on the same side of the vertical arm 203. More specifically, the rotating shaft 302 and the vertical arm 203 do not contact each other to avoid interference with the rotation of the rotating shaft 302. The rotating shaft 302 and the vertical arm 203 can be set. The gap between the arms 203 is 1-15mm. More specifically, with respect to the rotation direction of the rotating shaft 302, when the long arm 301 rotates, when the end of the long arm 301 reaches the bottom of the virtual circle, it rotates in the direction away from the cigarette. In other words, with respect to the vertical arm 203, if the side where the cigarette is stopped by the vertical arm 203 is set as the front side of the vertical arm 203, and the other side of the vertical arm 203 is set as the rear side, then when the end of the long arm 301 reaches the bottom of the virtual circle, it rotates in the direction away from the cigarette, thereby breaking and rupturing the cigarette.

[0047] Therefore, through the cross-type relative movement coordination of the vertical arm 203 and the long arm 301, the tobacco segment of the cigarette can be effectively destroyed without causing excessive damage to the cigarette paper or the filter segment. Therefore, in the subsequent screening process of the processed cigarettes, the recovered tobacco has high purity and the separation of tobacco and cigarette paper is also smooth.

[0048] Moreover, in the actual processing verification, compared with the previous processing technology of the circular screening cylinder, the tobacco recovered by the fence-type rake nail breaking and rupture device for cigarette paper provided by the present application has a significant improvement in purity, and the separation effect of tobacco and cigarette paper during screening is also significantly improved. The tobacco separation is more thorough and smooth, and the tobacco recovery rate is also improved.

[0049] More specifically, the cigarette channel 100 includes a working area 101 and a conveying area 102. The cigarette channel 100 is trough-shaped as a whole. The bottom of the cigarette channel 100 is planar in the working area 101. The fence component 2 and the rotating component 3 are both arranged in the range of the working area 101. The conveying area 102 is arranged in front of the working area 101. The conveying area 102 conveys the cigarette paper into the working area 101 and is broken and ruptured by the rotation of the long arm 301. The bottom of the cigarette channel 100 in the conveying area 102 can be a planar structure, and the cigarette paper can be conveyed by artificial loosening of cigarettes. A conveying plate can also be set at the bottom of the cigarette paper channel in the conveying area 102. The conveying plate is connected to a vibrating screen so that the conveying plate vibrates to convey cigarettes. More specifically, the conveying plate can be a planar structure to make the cigarette conveying efficiency higher. The conveying plate can also be a Fourier function The curved plate is in a continuous wave shape along the direction of movement of the cigarettes, and can straighten the cigarettes while conveying them, so that when the cigarettes are conveyed to the working area 101, the cigarettes and the rotating shaft 302 remain parallel, which is more conducive to the breaking and rupturing of the cigarettes.

[0050] More specifically, for the installation of the rotating shaft 302 and the cross arm 202, a mounting seat 6 can be set on both sides of the working area 101, and the two mounting seats 6 are relatively arranged on both sides of the cigarette channel 100. The cross arm 202 is detachably mounted on the top of the mounting seat 6 by screws, etc., and the two ends of the rotating shaft 302 can be rotatably mounted on the opposite sides of the mounting seat 6 by bearings. One end of the rotating shaft 302 extends outward from one side of the mounting seat 6 and is connected to the drive motor. The drive motor can be installed at a location such as an equipment rack.

[0051] In addition, a protective cover 7 can be provided, which is buckled on the upper part of the rotating component 3 and the fence component 2 to prevent cigarettes from splashing around when handling cigarettes, while improving safety and preventing accidental injuries caused by the equipment. Specifically, the two ends of the protective cover 7 can be detachably connected to the mounting seats 6 on both sides by screws, which is convenient for installation and disassembly.

[0052] More specifically, a workbench 1 can be set up, and the cigarette channel 100 is formed by enclosing two opposite side panels 11, and the space between the two side panels 11 is the cigarette channel 100, and the table top of the workbench 1 is the bottom of the cigarette channel 100. A discharge hopper 8 can also be set on one side of the workbench 1, and the discharge hopper 8 is connected to one side of the workbench 1 and corresponds to the position downstream of the working area 101. That is, the cigarettes are processed by the long arm 301 and the vertical arm 203 in the working area 101 and then discharged through the discharge hopper 8, and transferred to the subsequent process for processing. More specifically, the moving direction of the cigarettes on the table top of the workbench 1 can be tilted at a certain angle as a whole, which is beneficial to conveying cigarettes to the working area 101 on the one hand, and also beneficial to transferring the cigarettes in the working area 101 to the discharge hopper 8 on the other hand.

[0053] In addition, the embodiment of the present application also provides a fence-type rake nail breaking and fracturing method for cigarettes, which is applied to the fence-type rake nail breaking and fracturing device for cigarettes. Specifically, the method includes the following steps:

[0054] A. Determine the length and diameter of the defective cigarettes to be processed;

[0055] B. According to the diameter of the defective cigarette, determine the value of the preset gap between the bottom end of the vertical arm 203 and the bottom of the cigarette channel 100 and the value of the preset gap between the bottom of the outer edge of the virtual circumference of the rotation of the long arm 301 and the bottom of the cigarette channel 100. The values ​​of the two preset gaps are equal and recorded as h, which is smaller than the diameter of the defective cigarette determined in step A;

[0056] C. According to the length of the defective cigarette, determine the distance between the adjacent vertical arms 203 and the long arms 301 in the projection in the direction of the vertical rotation axis 302, and record the distance as T, which is less than the length of the defective cigarette determined in step A;

[0057] D. Set the rotating shaft 302 to be located at the front side of the vertical arm 203, where the vertical arm 203 faces the direction of the cigarette;

[0058] E. Place the cigarettes to be processed into the cigarette channel 100, which can be processed manually, by vibrating screen or Fourier function The curved vibrating plate moves the cigarettes to the working area 101 , and the driving device 4 is set as a driving motor, which drives the rotating shaft 302 to rotate at a speed of 30-120 r / min to break and rupture the defective cigarettes in the working area 101 .

[0059] Specifically, in one embodiment:

[0060] First, determine the length and diameter of the defective cigarettes to be processed, and obtain a length of 120 mm and a diameter of 5.5 mm. Then, set the value of the preset gap between the bottom end of the vertical arm 203 and the bottom of the cigarette channel 100 and the value of the preset gap between the bottom of the outer edge of the virtual circle of the rotation of the long arm 301 and the bottom of the cigarette channel 100 to 5 mm, satisfying the requirement that h is less than 5.5 mm. According to the obtained length and diameter of the cigarette, the projection along the length direction of the cigarette channel 100 sets the spacing T between adjacent vertical arms 203 and long arms 301 to 10.5 mm, and the diameter of the long arm 301 is set to 6 mm, the diameter of the vertical arm 203 is set to 12 mm, the diameter of the rotating shaft is set to 12 mm, and the rotating shaft is set to be located at the front side of the vertical arm 203, which is the direction in which the vertical arm 203 moves toward the cigarette. The minimum gap between the rotating shaft and the vertical arm 203 is set to 2 mm , increase the distance between the rotating shaft 302 and the vertical arm 203 as much as possible, so that the long arm 301 tends to be in a vertical state when it contacts the cigarette at the bottom, which is beneficial to improve the breaking and rupturing effect of the cigarette, and then put the cigarette to be processed into the cigarette channel 100, and move the cigarette to the working area 101 manually. The driving device 4 is set to a driving motor, and the driving motor drives the rotating shaft 302 to rotate at a speed of 90r / min to break and rupture the defective cigarettes in the working area 101. The processed cigarettes are discharged to the designated position through the discharge hopper 8 for subsequent screening. In this embodiment, compared with the previous processing process of the circular screening drum, the long arm 301 and the vertical arm 203 are intertwined and broken and torn. The purity of the tobacco is significantly improved after the processing, and the separation between the tobacco and the cigarette paper is also significantly more thorough and smooth during the process.
