Description

Technical Field

[0001] The present application relates to the technical field of waste cigarette sorting, and in particular to a cigarette rubbing device and a waste cigarette sorting system. Background Art

[0002] At present, all cigarette manufacturers will inevitably produce various unqualified and defective waste cigarettes during the production process. These waste cigarettes cannot be used for sales and circulation, and are called waste cigarettes. However, the tobacco contained in these waste cigarettes is still of high value, so it must be recycled. In the process of tobacco recycling, the most important step is to separate the tobacco from the cigarette paper.

[0003] In order to improve the integrity of the recycled tobacco, airflow air selection is currently used to blow the tobacco out of the paper tube of the waste cigarette. In order to ensure the thoroughness of blowing out the tobacco, it is generally necessary to rub the waste cigarettes before the airflow air selection step to loosen the tobacco wrapped in the paper tube. The existing cigarette rubbing mechanism is separated from the surface of the conveyor belt by a cigarette rubbing plate, and the distance between the cigarette rubbing plate and the surface of the conveyor belt is slightly smaller than the diameter of the waste cigarette. Therefore, when the waste cigarette enters the gap between the cigarette rubbing plate and the conveyor belt, the waste cigarette will generate friction with the cigarette rubbing plate in the opposite direction of the conveying direction, thereby rubbing the waste cigarette.

[0004] However, in the existing cigarette rubbing mechanism, the gap distance between the cigarette rubbing plate and the conveyor belt is constant, which easily leads to poor rubbing effect of waste cigarettes, low looseness of tobacco, and difficulty in separating tobacco from cigarette paper, thus affecting the effect of airflow selection.

Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0036] In the description of the present application, it should be understood that if these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0037] In addition, if these terms "first" and "second" appear, these terms are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0038] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined.

[0040] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right", and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0041] The embodiment of this application provides a waste cigarette sorting system, and the waste cigarette sorting system includes a cigarette rubbing device. It can be understood that the cigarette rubbing device is used to rub the waste cigarettes to loosen the tobacco wrapped in the paper tube. Further, the waste cigarette sorting system further includes a pneumatic separation device. The rubbed waste cigarettes can enter the pneumatic separation device, and the pneumatic separation device blows out the tobacco in the paper tube through air flow, so as to realize the separation of the tobacco and the cigarette paper.

[0042] Specifically, please refer to Figure 1 , the cigarette rubbing device 100 includes a cigarette magazine 10, rollers 11, a first conveyor belt 12, a second conveyor belt 13, and a cigarette rubbing assembly 14.

[0043] The cigarette bin 10 is used to hold waste cigarettes, and its material can be metal or plastic. The cigarette bin 10 has a smoke outlet 101, through which waste cigarettes can be discharged. It can be understood that, in order to facilitate the discharge of waste cigarettes, the cigarette bin 10 is generally a funnel-shaped structure with a thick top and a thin bottom, and the smoke outlet 101 is opened at the lower end of the cigarette bin 10. In this way, the volume of the cigarette bin 10 can be effectively increased to hold more waste cigarettes, and the waste cigarettes can be better guided out of the smoke outlet 101.

[0044] In some embodiments, the cigarette bin 10 can vibrate. The cigarette bin 10 can be installed on a vibration base (not shown in the figure) to generate vibration, or the cigarette bin 10 itself can be driven to vibrate by a driving member. In this way, the vibration can effectively prevent waste cigarettes from clogging the cigarette outlet 101, thereby improving the efficiency of waste cigarette sorting.

[0045] See also Figure 1 The roller 11 is rotatably connected to one end of the cigarette bin 10 near the cigarette outlet 101 and is spaced apart from the cigarette bin 10. It is understandable that the roller 11 is rotatably arranged. For example, the roller 11 can be mounted on a bracket or a housing through a rotating shaft and driven by a driving member such as a motor.

[0046] The outer circumferential surface of the roller 11 is provided with a plurality of tooth grooves 111 at intervals along the circumferential direction. It is understandable that each tooth groove 111 can accommodate waste cigarettes, and in general, each tooth groove 111 can and only can accommodate one waste cigarette. Thus, when the roller 11 rotates, the tooth grooves 111 on the roller 11 can sequentially pass the side of the cigarette outlet 101 of the cigarette bin 10, and can accommodate and convey the waste cigarettes discharged from the cigarette outlet 101.

[0047] The tooth grooves 111 are in the shape of long strips and match the shape and size of the waste cigarettes. Furthermore, the long strip tooth grooves 111 extend generally along the rotation axis direction of the roller 11 on the outer peripheral surface of the roller 11 .

[0048] The specific shape of the tooth groove 111 is not limited. For example, the tooth groove 111 may be a V-shaped groove, a U-shaped groove, or an arc-shaped groove.

[0049] See also Figure 1 The first conveyor belt 12 includes an arc segment 121 and a straight segment 122 connected to the arc segment 121 . The arc segment 121 is wound around a portion of the outer circumferential surface of the roller 11 on a side away from the cigarette bin 10 .

[0050] It should be noted that the arc section 121 and the straight section 122 of the first conveyor belt 12 do not refer to a certain fixed area, but are the names of the parts of the first conveyor belt 12 that play specific roles. It can be understood that as the first conveyor belt 12 rotates, the areas referred to by the arc section 121 and the straight section 122 will also be converted with each other. In this way, after the waste cigarette butts fall into different tooth grooves 111 from the cigarette outlet 101, during the rotation of the roller 11, the arc section 121 wound around the outer circumferential surface of the roller 11 can cooperate with the tooth grooves 111 to prevent the waste cigarette butts from falling out of the tooth grooves 111.

[0051] In a preferred embodiment, please refer to Figure 1 , the roller 11 and the first conveyor belt 12 can move synchronously, that is, the rotation speeds and rotation directions of the roller 11 and the first conveyor belt 12 are the same. In this way, the roller 11 and the arc section 121 can maintain a relatively static state, and further, it can be avoided that the waste cigarette butts are taken out of the tooth grooves 111 due to the relative movement between the roller 11 and the first conveyor belt 12.

[0052] In some embodiments, please refer to Figure 1 , the straight section 122 of the first conveyor belt 12 is tangent to the outer circumferential surface of the roller 11. That is to say, the straight section 122 is in contact with the surface of the roller 11. In this way, when the rotation of the roller 11 aligns the opening of the tooth groove 111 downward along the gravity direction, there is no height difference between the tooth groove 111 and the surface of the straight section 122, and the waste cigarette butts will not rebound during the process of being released from the opening of the tooth groove 111, which can improve the high orderliness of the waste cigarette butts on the surface of the straight section 122 and is beneficial to the subsequent work of the waste cigarette butt processing equipment.

[0053] Please refer to Figure 1 and Figure 2 , the second conveyor belt 13 includes a first conveyor section 131 and a second conveyor section 132. The first conveyor section 131 and the second conveyor section 132 are connected end to end to form a ring. The first conveyor section 131 faces the cigarette outlet 101 and extends to the side of the roller 11 close to the cigarette magazine 10, and the second conveyor section 132 faces the straight section 122 and is arranged in parallel and at intervals with the straight section 122.

[0054] It should be noted that the first conveyor section 131 and the second conveyor section 132 of the second conveyor belt 13 do not refer to a certain fixed area, but are the names of the parts of the second conveyor belt 13 that play specific roles. It can be understood that as the second conveyor belt 13 rotates, the areas referred to by the first conveyor section 131 and the second conveyor section 132 will also be converted with each other.

[0055] In this application, please refer to Figure 1 and Figure 2, the cigarette storage 10, the roller 11, and the first conveying section 131 enclose each other to jointly form a material taking space (not shown in the figure). The waste cigarette sticks discharged from the cigarette outlet 101 will enter the material taking space. The first conveying section 131 can convey the waste cigarette sticks in the material taking space towards the roller 11, so that the waste cigarette sticks can enter the tooth grooves 111 and be conveyed through the roller 11.

[0056] It can be understood that both the first conveyor belt 12 and the second conveyor belt 13 can perform reciprocating motions. Specifically, both the first conveyor belt 12 and the second conveyor belt 13 are driven by driving wheels (not shown in the figure). Moreover, through the arrangement of the positions of multiple driving wheels, the first conveyor belt 12 and the second conveyor belt 13 can both be in a preset shape as a whole.

[0057] Please refer to Figure 1 and Figure 2 , the cigarette rubbing assembly 14 is movably connected to the second conveying section 132 and can remain stationary with the straight section 122 when the second conveyor belt 13 is conveying. The surface of the cigarette rubbing assembly 14 facing the straight section 122 and the conveying surface of the straight section 122 form a cigarette rubbing space 15.

[0058] It can be understood that the height of the cigarette rubbing space 15 is generally slightly smaller than the diameter of the waste cigarette stick, so the waste cigarette stick entering the cigarette rubbing space 15 can be squeezed to loosen the tobacco in the paper tube. Specifically, when the waste cigarette stick is released from the tooth groove 111 onto the straight section 122 and the straight section 122 continues to rotate and drives the waste cigarette stick into the cigarette rubbing space 15, a frictional force opposite to the conveying direction is generated between the waste cigarette stick and the inner wall of the cigarette rubbing space 15. While the straight section 122 drives the waste cigarette stick forward, the waste cigarette stick will also rotate in the opposite direction, thereby realizing the rubbing of the waste cigarette stick.

[0059] The cigarette rubbing device 100 provided by the embodiment of the present application forms a cigarette rubbing space 15 through the surface of the cigarette rubbing assembly 14 facing the straight section 122 and the conveying surface of the straight section 122. After the waste cigarette stick enters the cigarette rubbing space 15, a frictional force opposite to the conveying direction will be generated between the waste cigarette stick and the inner wall of the cigarette rubbing space 15 to realize the rubbing of the waste cigarette stick and make the tobacco in the paper tube loosen, so as to facilitate the subsequent process of separating the tobacco and the cigarette paper of the waste cigarette stick.

[0060] In some embodiments, please refer to Figure 2 and Figure 3, the surface of the cigarette rolling assembly 14 facing the straight section 122 is the cigarette rolling surface 1415, and the cigarette rolling surface 1415 is inclined towards the side close to the straight section 122 along the conveying direction of the straight section 122. Thus, along the conveying direction of the straight section 122, the height of the cigarette rolling space 15 gradually decreases. That is to say, the frictional force generated between the waste cigarette rod and the inner wall of the cigarette rolling space 15 will gradually increase after the waste cigarette rod enters the cigarette rolling space 15, so as to achieve more sufficient rubbing of the waste cigarette rod, thereby effectively ensuring that the tobacco shreds are loosened in the paper tube.

[0061] In some embodiments, please refer to Figure 1 and Figure 2 , there is a preset angle D between the cigarette rolling surface 1415 and the horizontal plane where the straight section 122 is located, and the preset angle D satisfies the condition: 0° < D < 5°. Preferably, the preset angle D between the cigarette rolling surface 1415 and the horizontal plane where the straight section 122 is located is 4°. Thus, along the conveying direction of the straight section 122, the change amount of the height of the cigarette rolling space 15 is relatively moderate, and further ensures that the change amount of the frictional force generated between the waste cigarette rod and the inner wall of the cigarette rolling space 15 is also relatively moderate, thereby avoiding the situation that the waste cigarette rod is damaged due to excessive frictional force, and also being able to avoid the situation that the waste cigarette rod is blocked due to excessive frictional force.

[0062] It should be noted that the specific value range of the preset angle D is not limited. The specific value range of the preset angle D is obtained through experimental tests. The relevant parameters, steps, etc. of the experimental tests related to the intermediate value of the preset range are all conventional techniques for those skilled in the art and will not be elaborated here.

[0063] In some embodiments, please refer to Figure 4 and Figure 5 , the cigarette rolling surface 1415 has a preset length L along the conveying direction of the straight section 122, and the preset length L satisfies the condition: 500mm ≤ L ≤ 550mm. Preferably, the cigarette rolling surface 1415 has a preset length L of 522mm along the conveying direction of the straight section 122. It can be understood that by extending the length of the cigarette rolling surface 1415 along the conveying direction of the straight section 122 in this application, the distance of the waste cigarette rod from the cigarette rolling space 15 to the next process can be shortened, so as to increase the rubbing duration of the waste cigarette rod in the cigarette rolling space 15, which is beneficial to enhancing the rubbing effect. At the same time, it can reduce the time of ineffective work of the waste cigarette rod after being discharged from the cigarette rolling space 15, thereby playing a role in energy saving and efficiency improvement.

[0064] It should be noted that the specific value range of the preset length L is not limited. The specific value range of the preset length L is obtained through experimental tests. The relevant parameters, steps, etc. of the experimental tests related to the intermediate value of the preset range are all conventional techniques for those skilled in the art and will not be elaborated here.

[0065] In some embodiments, please refer to Figure 4and Figure 5 The cigarette rolling assembly 14 includes a main body 141 and a rotating wheel 142. The main body 141 is arranged along the conveying direction of the straight line segment 122, and the surface of the main body 141 facing the straight line segment 122 forms a cigarette rolling surface 1415. The rotating wheel 142 is connected to both ends of the main body 141 along the conveying direction of the straight line segment 122, and the rotating wheel 142 is movably connected to the second conveying segment 132 and can rotate relative to the second conveyor belt 13.

[0066] It can be understood that when the second conveying segment 132 is operating, the rotating wheel 142 can rotate relative to the second conveying segment 132, so that the main body 141 can remain stationary relative to the straight line segment 122, thereby ensuring the stability of the cigarette rolling space 15. At the same time, the rotating wheel 142 can prevent the main body 141 from contacting and wearing with the second conveyor belt 13, thereby effectively improving the service life of the product.

[0067] In some embodiments, please refer to Figure 4 and Figure 5 The main body 141 includes a main board 1411 and a plurality of friction sheets 1413. An installation groove 1412 is formed by recessing the surface of the main board 1411 facing the straight line segment 122. The bottom wall of the installation groove 1412 is inclined towards the side close to the straight line segment 122 along the conveying direction of the straight line segment 122. Each friction sheet 1413 is evenly laid on the bottom wall of the installation groove 1412, and the side surfaces of each friction sheet 1413 facing away from the bottom wall protrude from the installation groove 1412 to jointly form the cigarette rolling surface 1415.

[0068] It can be understood that the included angle between the bottom wall of the installation groove 1412 and the horizontal plane where the straight line segment 122 is located satisfies a preset included angle D. In this way, the cigarette rolling surface 1415 jointly formed by evenly laying each friction sheet 1413 on the bottom wall of the installation groove 1412 also satisfies the preset included angle D. In this way, along the conveying direction of the straight line segment 122, the height of the cigarette rolling space 15 gradually decreases, and the change amount of the height of the cigarette rolling space 15 is relatively moderate. Furthermore, it is ensured that the change amount of the frictional force generated between the waste cigarette rod and the inner wall of the cigarette rolling space 15 is also relatively moderate, so as to be able to rub the waste cigarette rod more fully, effectively ensuring that the tobacco shreds are loosened in the paper tube, and at the same time being able to avoid the situation that the waste cigarette rod is damaged due to excessive frictional force, and being able to avoid the situation that the waste cigarette rod is blocked due to excessive frictional force.

[0069] In some embodiments, please refer to Figure 4 and Figure 5 At least some of the side surfaces of all the friction sheets 1413 facing away from the bottom wall are provided with material guiding grooves 1414, and the material guiding grooves 1414 extend to the edges of the friction sheets 1413 and communicate with the external space.

[0070] It can be understood that foreign matters in the cigarette rolling space 15, such as cut tobacco, dust, etc., can enter the material guiding groove 1414. After the waste cigarette enters the cigarette rolling space 15, the acting force generated by the extrusion of the waste cigarette and the friction plate 1413 can discharge the foreign matters in the material guiding groove 1414 to the outside world, thereby preventing the foreign matters from blocking the cigarette rolling space 15.

[0071] For the above-mentioned cigarette rolling device 100, the waste cigarette is discharged from the cigarette outlet 101 of the cigarette magazine 10 and enters the material taking space. Through the first transmission section 131 of the second transmission, the waste cigarette in the material taking space can be conveyed to the roller 11 so that the waste cigarette falls into different tooth grooves 111 of the roller 11; then the roller 11 rotates to realize the conveyance of the waste cigarette; and during the conveyance of the waste cigarette by the roller 11, the first transmission belt can move synchronously with the roller 11. The arc section 121 of the first transmission belt is wound around the outer circular surface of the roller 11, which can prevent the waste cigarette from falling off from the tooth groove 111; the straight section 122 of the first conveyor belt 12 is tangent to the outer circular surface of the roller 11. When the opening of the tooth groove 111 of the roller 11 faces downward along the gravity direction, the waste cigarette can be released from the opening of the tooth groove 111 to the straight section 122; further, the straight section 122 guides the waste cigarette into the cigarette rolling space 15. By generating a frictional force in the opposite direction of the conveying direction between the waste cigarette and the inner wall of the cigarette rolling space 15, the waste cigarette can be kneaded so that the cut tobacco in the paper tube becomes loose, thus facilitating the subsequent process of separating the cut tobacco and the cigarette paper of the waste cigarette. Among them, by setting the cigarette rolling surface 1415 to be inclined toward the side close to the straight section 122 along the conveying direction of the straight section 122, the height of the cigarette rolling space 15 gradually decreases along the conveying direction of the straight section 122, so that the frictional force received by the waste cigarette during the conveyance in the cigarette rolling space 15 gradually increases, thereby realizing more sufficient kneading of the waste cigarette and effectively ensuring that the cut tobacco becomes loose in the paper tube.

[0072] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0073] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
