Description

Tobacco shred separating device and tobacco rubbing mechanism thereof

Technical Field

The invention relates to the technical field of cigarette machinery, in particular to a tobacco shred separating device and a cigarette rolling mechanism thereof.

Background

At present, various cigarette production enterprises can generate various unqualified and defective cigarettes which are difficult to avoid in the production process, and the cigarettes cannot be used for sale and circulation, and are called as waste cigarettes. However, the cut tobacco contained in these waste cigarettes is still of high value and must be recovered. In the tobacco shred recycling process, the most important step is to separate the tobacco shred from the cigarette paper.

In order to improve the integrity of the recovered cut tobacco, air blowing is frequently adopted to blow the cut tobacco out of a paper tube of waste tobacco. In order to ensure the completeness of the blowing of the cut tobacco, the waste tobacco is generally kneaded before the blowing step, so as to loosen the cut tobacco wrapped in the paper tube. The existing cigarette rubbing mechanism comprises a cigarette warehouse, a switch board capable of being opened and closed periodically, a conveying belt and a cigarette rubbing board arranged above the conveying belt. The regular opening and closing of the switch board can make the waste cigarette fall onto the conveying belt, and the conveying belt bears the cigarettes and conveys the cigarettes forwards. Because the distance between the cigarette rubbing plate and the surface of the conveying belt is slightly smaller than the diameter of the waste cigarettes, when the waste cigarettes enter the gap between the cigarette rubbing plate and the conveying belt, the waste cigarettes and the cigarette rubbing plate generate a friction force opposite to the conveying direction, and the cigarettes are rubbed.

However, when the waste cigarettes enter the gap between the cigarette rubbing plate and the conveying belt, the cigarettes are easily twisted together during the cigarette rubbing process due to the small interval between the adjacent cigarettes and even the overlapping, and the cigarettes are broken or stuck in the cigarette rubbing channel. Therefore, the existing cigarette twisting mechanism causes poor reliability of the tobacco shred recycling process.

Referring to fig. 1, the present invention provides a tobacco shred separating mechanism and a tobacco twisting mechanism 100. Wherein, the tobacco shred separating mechanism comprises an air blowing mechanism (not shown) and a cigarette twisting mechanism 100.

The cigarette kneading mechanism 100 is used for kneading waste cigarette to knead the cut tobacco wrapped in the paper tube. Furthermore, the kneaded waste cigarette can enter an air blowing mechanism, and the air blowing mechanism blows out the cut tobacco of the paper tube in an air blowing mode, so that the separation of the cut tobacco and the cigarette paper is realized.

Referring to fig. 2, the cigarette twisting mechanism 100 according to the preferred embodiment of the present invention includes a cigarette storage 110, a roller 120, a conveyor belt 130 and a cigarette conveying assembly 140. The cigarette storage 110, the roller 120, the conveyor belt 130 and the cigarette conveying assembly 140 may be mounted on the same bracket, or may be housed and mounted in the same housing.

The smoke storage 110 is used for containing waste smoke and can be made of metal or plastic. The smoke box 110 has a smoke outlet (not shown), through which waste smoke can be discharged in sequence. To facilitate the discharge of waste tobacco, the tobacco storage 110 is generally in a funnel-shaped structure with a thick upper part and a thin lower part. In particular, in this embodiment, the smoke reservoir 110 may vibrate. The cigarette storage 110 can be arranged on a vibration base, and the waste cigarette can be effectively prevented from blocking the cigarette outlet through vibration.

Referring to fig. 3, a plurality of tooth grooves 121 are formed on the outer circumferential surface of the roller 120, and the plurality of tooth grooves 121 are spaced apart from each other in the circumferential direction of the roller 120. Wherein the roller 120 is rotatably disposed. The roller 120 may be mounted to the bracket or the housing through a rotating shaft and driven by a driving member such as a motor. The tooth grooves 121 are long and matched with the shape and size of the waste smoke. The gullet 121 may be a V-shaped groove, a U-shaped groove, or a circular arc-shaped groove. Typically, each tooth slot 121 can hold one and only one waste cigarette. Therefore, when the waste smoke is recovered for different models, the corresponding model of the roller 120 may be replaced. Further, the elongated spline 121 extends generally along the rotation axis of the roller 120 on the outer circumferential surface of the roller 120.

Further, the outer peripheral surface of the roller 120 includes a material taking area 101, a conveying area 103, and a material discharging area 102, which are connected in sequence. The material taking area 101, the conveying area 103 and the material discharging area 102 all extend along the peripheral circle of the roller 120. Moreover, when processing the waste smoke, the rotation direction of the roller 120 is from the material taking area 101 to the conveying area 103 and finally to the material discharging area 102. I.e. in the counter-clockwise direction as shown in fig. 1. The waste smoke firstly enters the tooth grooves 121 in the material taking area 101, is conveyed through the conveying area 103, and then enters the blanking area 102 to be discharged from the tooth grooves 121.

It should be noted that the material taking area 101, the conveying area 103, and the material discharging area 102 are not particularly limited to a fixed area on the outer peripheral surface of the roller 120, but refer to a specific portion of the roller 120. For example, a certain area of the outer peripheral surface of the roller 120 is the material taking area 101 at the initial position, and as the roller 120 rotates, the area is sequentially switched to the conveying area 103 and the blanking area 102, and the cycle is repeated.

Specifically, in the present embodiment, the depth direction of each tooth groove 121 is inclined with respect to the radial direction of the roller 120. Specifically, the depth direction of the teeth slots 121 refers to a direction in which the teeth slots 121 are recessed with respect to the outer circumferential surface of the roller 120. Since the depth direction is inclined with respect to the radial direction, the tooth grooves 121 are all inclined grooves.

Also, when the roller 120 is operated, the tooth grooves 121 are inclined in the same direction as the rotation direction of the roller 120. Therefore, the supporting effect of the tooth grooves 121 on the waste smoke is better, and the waste smoke can be effectively prevented from falling off from the tooth grooves 121 in the lifting process.

The conveyor belt 130 may reciprocate. Specifically, the conveyor belt 130 is driven by a drive wheel (not shown). Moreover, the plurality of driving wheels are arranged by position, so that the entire conveyor belt 130 can be in a predetermined shape. The transmission belt 130 includes an arc segment 131 and a straight segment 133 connected to the arc segment 131. The material taking area 101 is located at one end of the arc-shaped section 131 far away from the straight section 133, and the blanking area 102 is located at the connection position of the arc-shaped section 131 and the straight section 133.

Similarly, the arc-shaped segment 131 and the straight segment 133 are not specific to a fixed region of the conveyor belt 130, but refer to a specific functional region of the conveyor belt 130. As the conveyor 130 runs, the areas indicated by the arc segments 131 and the straight segments 133 are also converted into each other. For example, a region of the conveyor belt 130, which in the initial position surrounds the conveying region 103, is referred to as an arcuate segment 131. And as the roller 120 rotates, the area will translate into a straight line segment 133.

The arc-shaped segment 131 is wound around the conveying area 103 of the roller 120. The waste smoke can fall into different tooth grooves 121 after entering the material taking area 101 through the smoke outlet. As the roller 120 rotates, the waste smoke in the tooth slot 121 passes through the conveying area 103, and the waste smoke is prevented from being separated from the tooth slot 121 by the cooperation of the arc-shaped sections 131. Finally, the waste fumes pass from the blanking area 102 in turn into a straight section 133. Since the plurality of tooth grooves 121 are spaced apart from each other, when the waste fumes are sequentially discharged in the blanking region 102, the spacing between the adjacent waste fumes is maintained.

In this embodiment, the surface of the straight line segment 133 is tangent to the blanking region 102 of the roller 120. That is, the straight line segment 133 is in contact with the surface of the roller 120. Therefore, when the waste fume transferred to the blanking region 102 is released from the inside of the tooth slot 121, there is no or very little difference in height between the tooth slot 121 and the surface of the straight line segment 133. At this time, the waste smoke is not bounced off by the violent impact during the release from the tooth slots 121 to the conveyor belt 130, so that the waste smoke maintains a high degree of order on the surface of the straight section 133.

In this embodiment, the roller 120 and the conveyor belt 130 can move synchronously. Specifically, the rotation speed and the rotation direction of the roller 120 and the conveyor belt 130 are the same. Therefore, the roller 120 and the arc-shaped segment 131 can be kept relatively still, so that the waste smoke in the tooth slot 121 is prevented from being brought out due to the relative movement of the roller 120 and the conveyor belt 130.

Further, a smoke kneading passage 104 is formed in a predetermined area of the straight line segment 133. The smoke channel 104 can be formed by matching the straight line segment 133 with a plate-shaped structure and a belt-shaped structure which are suspended on the surface of the straight line segment 133. The height of the cigarette twisting channel 104 is generally slightly less than the diameter of the waste cigarette, so that the waste cigarette entering the cigarette twisting channel 104 can be squeezed, and the tobacco shreds are loosened in the paper tube. Specifically, when the conveyor belt 120 continues to operate and drives the waste cigarette into the cigarette rubbing channel 104, the waste cigarette and the inner wall of the cigarette rubbing channel 104 generate a friction force opposite to the conveying direction. The waste cigarette is also rotated in the opposite direction while being driven to move forwards by the conveyor belt 120, so that the waste cigarette is kneaded.

Since the waste fumes are sequentially discharged in the blanking area 102, the adjacent waste fumes maintain a sufficient interval. Further, the degree of order of the exhaust fumes arranged on the straight line segment 133 is high. Therefore, the condition that adjacent waste cigarettes are mutually wound can be avoided during the cigarette twisting operation, so that the waste cigarettes are prevented from being broken or stuck, and the reliability of the tobacco shred recycling process is effectively improved.

In this embodiment, the conveying zone 103 has an extent greater than one-half of the circumference of the outer circumferential surface of the roller 120. That is, more than one half of the outer circumference of the roller 120 is covered by the arc-shaped section 131. The arc-shaped section 131 is used for covering the opening of the tooth slot 121 and limiting the waste smoke in the tooth slot 121. Thus, as the waste fume is lifted with the rotation of the roller 120, the waste fume can enter the range of the arc-shaped segment 131 before reaching the apex of the roller 120. And due to the limiting effect of the arc-shaped section 131, the waste smoke can be further prevented from falling off from the tooth groove 121 in the lifting process.

As mentioned above, the width of the gullet 121 on the roller 120 is only slightly larger than the diameter of the waste smoke. This is because, if the tooth grooves 121 are too wide, the waste smoke may be shaken in the tooth grooves 121, which may affect the effect of subsequent waste smoke release and may adversely affect the degree of order of the waste smoke arranged on the straight line segment 133. However, the waste cigarette to be treated generally does not have a strict and regular shape like a genuine cigarette, and the waste cigarette generally has the phenomena of small deformation, bending, even breaking, paper tube scattering and the like, which causes the poor effect of the roller 120 in taking the cigarette into the slot, and affects the efficiency of the device in treating the waste cigarette. Even, the exhaust fume that can't go into the groove smoothly can be piled up in the material area 101 of getting, leads to the equipment card to die.

It is the smoke delivery assembly 140 that addresses the above-mentioned problems. The smoke delivery assembly 140 is configured to carry the waste smoke exiting through the smoke outlet and convey the waste smoke toward the material extraction area 101. That is, the waste fumes are discharged from the fume chamber 110 and then fall onto the delivery assembly 140 rather than directly into the material extraction area 101. The smoke delivery assembly 140 may first buffer the waste smoke. More importantly, the smoke delivery assembly 140 provides a force on the waste smoke directed toward the material extraction zone 101 and moves the waste smoke toward the material extraction zone 101. In this way, the waste cigarettes falling onto the cigarette feeding assembly 140 are more likely to enter the tooth grooves 121 by a lateral force, thereby significantly improving the effect of taking the cigarettes into the grooves.

Specifically, in this embodiment, the smoke feeding assembly 140 includes an endless smoke feeding belt 141, and a conveying surface of the smoke feeding belt 141 faces the smoke outlet and extends to the material taking area 101.

The material and structure of the fume conveying belt 141 may be the same as those of the conveyor belt 130, and is generally driven by a driving wheel (not shown). The conveying surface of the cigarette conveying belt 141 is used for carrying waste cigarettes discharged from the cigarette outlet. The running direction of the smoke-feeding belt 141 is adapted to the rotating direction of the roller 120. As shown in FIG. 1, smoke belt 141 is operated counterclockwise.

It should be noted that in other embodiments, smoke delivery assembly 140 may take other forms. For example, the smoke delivery assembly 140 may be a row of side-by-side transport rollers that rotate in a direction toward the take-up area 101. The transport rollers rotate to drive the waste cigarettes to sequentially pass through the transport rollers and finally enter the material taking area 101.

Further, in the present embodiment, the conveying surface of the tobacco feeding belt 141 extends obliquely from the tobacco outlet toward the material extracting section 101. That is, the conveying surface of the smoke feeding belt 141 has a certain slope. Specifically, as shown in fig. 1, the end of the conveying surface near the smoke outlet is higher, and the end near the material taking area 101 is lower. Yet does not divide the conveying surface to extend from right to left downwards. Therefore, due to the height difference, when the waste smoke falls to the conveying surface, the waste smoke can actively roll to the material taking area 101 under the action of gravity, so that the material taking effect of the roller 120 is further improved.

In this embodiment, the surface of the cigarette feeding belt 141 facing away from the cigarette outlet is spaced from the straight line segment 133, so as to cooperate with the straight line segment 133 to form the cigarette twisting channel 104.

Specifically, the fume conveying belt 141 is located on the side of the straight line segment 133 facing the roller 120. The extending direction of the smoke feeding belt 141 is designed to coincide with the extending direction of the straight line segment 133. As shown in fig. 1, the endless smoke-feeding belt 141 has two upper and lower conveying surfaces. The downwardly facing transport surface cooperates with the straight segment 133 to form the smoke twisting passage 104. Therefore, the cigarette conveying belt 141 not only can play a role of conveying the waste cigarettes, but also can be used for cigarette twisting. On the premise of providing the cigarette feeding belt 141, there is no need to additionally provide a cigarette twisting component, so the structure of the cigarette twisting mechanism 100 can be effectively simplified.

The rotation speed of the smoke feeding belt 141 can be adjusted. Therefore, the rotation speed of the cigarette feeding belt 141 can be adjusted according to the requirement, so that the cigarette feeding belt 141 and the straight line segment 133 have a required speed difference, and a good cigarette rubbing effect is obtained to adapt to different types of waste cigarettes.

Further, in this embodiment, the distance between the fume feeding belt 141 and the straight section 133 is adjustable.

Specifically, the distance can be adjusted by adjusting the position and the tension degree of the driving wheel. The size of the smoke twisting channel 104 can be adjusted by adjusting the distance between the smoke feeding belt 141 and the straight line segment 133. When the type of waste cigarette to be kneaded varies, the size of the kneading passage 104 can be adjusted to fit the diameter of the waste cigarette. Therefore, the cigarette rubbing mechanism 100 is suitable for waste cigarette treatment of various models, and the application range is effectively improved.

It should be noted that in other embodiments, the smoke passage 104 may be obtained in other ways. For example, a cigarette rubbing plate can be disposed at a predetermined position of the straight section 133, opposite to the surface of the straight section 133, and the cigarette rubbing plate can be mounted on the bracket or the housing. Moreover, the smoke-kneading board can be lifted and lowered in the direction perpendicular to the surface of the straight line section 133, so that the size of the smoke-kneading channel 104 can be adjusted.

Furthermore, in the present embodiment, one end of the cigarette feeding belt 141 close to the blanking area 101 is warped in a direction away from the straight line segment 133, so that one end of the cigarette rubbing channel 104 close to the blanking area 101 is funnel-shaped.

The warping of the belt 141 can be achieved by controlling the outer diameter of the drive wheels or the arrangement of the drive wheels. For example, the driving wheel at the left end of the belt 141 is set to be a larger distance from the surface of the straight line segment 133; alternatively, the outer diameter of the drive pulley at the left end of the smoke feeding belt 141 may be set small.

Therefore, when the waste cigarette comes from the blanking area 102 to the straight line segment 133 and enters the cigarette twisting channel 104 through the straight line segment 133, the funnel-shaped opening of the cigarette twisting channel 104 can play a better guiding role, so that the waste cigarette can be prevented from being blocked at the inlet of the cigarette twisting channel 104, and the smooth proceeding of the cigarette twisting process can be ensured.

According to the cut tobacco separating device and the cigarette twisting mechanism 100 thereof, waste cigarettes in the cigarette warehouse 110 can fall to the cigarette feeding assembly 140 from the cigarette outlet, and are conveyed to the material taking area 101 by the cigarette feeding assembly 140. As the roller 120 rotates, the waste fumes from the material extraction area 101 may fall into different tooth slots 121. After the roller 120 rotates a certain angle, the waste smoke in the tooth slot 121 is driven to pass through the conveying area 103, and finally enters the straight line segment 133 of the conveyor belt 130 from the blanking area 102 in sequence. The conveyor belt 130 continues to operate, so that the waste cigarette can be driven to enter the cigarette twisting channel to complete the cigarette twisting operation. Because the tooth grooves 121 on the roller 120 are mutually spaced, and the waste smoke is transferred from the material taking area 101 to the material discharging area 102 through the cooperation of the tooth grooves 121 and the arc-shaped sections 131. Therefore, when the waste cigarettes are sequentially released in the blanking area 102, a sufficient interval can be kept between the adjacent waste cigarettes, so that the adjacent waste cigarettes are prevented from being intertwined when the cigarette twisting operation is carried out. Therefore, the cut tobacco separating device and the cigarette rolling mechanism 100 thereof can improve the reliability of cut tobacco recovery.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be understood as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
