Description

Technical Field

[0001] The present invention relates to a spiral cutting and accelerating motion device for defective pearl bursting cigarettes, and belongs to the technical field of cigarette equipment. Background Art

[0002] During the production process of cigarettes, it is inevitable to produce a certain number of defective cigarettes. The defective cigarettes need to be transported to the defective cigarette treatment line for processing, where the tobacco shreds, filter tips and cigarette paper are completely separated, and then the recycled tobacco shreds are reused. Pearl bursting cigarettes are a type of cigarette that has emerged in recent years. The pearl bursting, also known as a brittle capsule, refers to a small liquid gum bead embedded in the cigarette filter tip in the form of a capsule. Pearl bursting cigarettes have the characteristics of flexibility, diversity and personalization, and can meet the changing taste and preference needs of consumers. At present, pearl bursting cigarettes have shown relatively strong vitality in the market and have great development space. To adapt to market competition, pearl bursting cigarettes have been gradually promoted in major domestic cigarette factories. However, in the process of defective pearl bursting cigarettes, it is not allowed to separate the tobacco shreds from the cigarette paper and filter tips on the existing defective cigarette treatment equipment, because the pearl bursting in the filter tip will damage the liquid outflow and cause tobacco shred pollution. At present, defective pearl bursting cigarettes are all manually processed. Generally, for a cigarette packing and wrapping equipment producing pearl bursting cigarettes, at least 5 workers are required to manually process the defective pearl bursting cigarettes in each shift, which is time-consuming and laborious, with low efficiency, a long tobacco shred recycling cycle, water loss of tobacco shreds, ultimately resulting in broken tobacco shreds, low tobacco shred recovery rate, and increased production costs for enterprises.

[0003] A defective cigarette treatment device with the patent number ZL202021573210.7 is an invention patent applied for by our unit and has been authorized. Now the external manufacturing unit has manufactured a prototype according to our requirements. Through on-site experiments, the core functional part basically meets the requirements. The designed conveying channel for defective cigarette sticks of this invention uses two circular knives that are both horizontally arranged, and the two circular knives cut the cigarette sticks along the axis of the cigarette sticks.

[0004] Existing Problems:

[0005] In actual production experiments, the cigarette stick conveying channel conveys the cigarette sticks horizontally, and two circular knives are also horizontally arranged. The two circular knives cut the cigarette sticks along the axis of the cigarette sticks. Since the cigarette sticks move linearly through the horizontal circular knife cutting, the circumferential direction of the cigarette sticks is in a random and arbitrary position, which is uncontrollable. There is a 1-mm glue-free area at the buckle where the cigarette paper wrapping each cigarette is adhered. When the 1-mm glue-free area at the cigarette butt joint is cut by the horizontal circular knife, filamentous fine paper scraps are formed, and these filamentous fine paper scraps will fall together with the tobacco shreds when the tobacco shreds and paper scraps are sorted by a vibrating sieve in the next process, resulting in a reduction in the purity of the sorted tobacco shreds.

[0006] The upgraded version adopted by our unit: A cutting device for defective pearl bursting cigarettes with a variable diameter and inclined channel. The patent authorization announcement number is: CN 21864875 U. Although this device greatly reduces the generation of fine paper scraps and solves the problem of fine paper scraps being mixed in the cut tobacco after sorting, when cutting, the forces on both sides of the cigarette butt incision are inconsistent. After cutting, one side of the cigarette paper is smooth and the other side has stubble, and the cutting effect is not ideal. The round blade edge must be absolutely sharp, and at the same time, the rotational speed of the round knife needs to be increased to 5000 revolutions per minute for the device to basically work properly. This requires frequent replacement of the cutting round knife and will also accelerate the premature damage of the bearings of the round knife rotating mechanism. At the same time, the cigarette is cut obliquely and the round knife cuts horizontally in the cutting groove. The non-glued joint along the generatrix of the cigarette will not be cut in the whole strip. Although it can avoid the generation of fine paper scraps, due to the uneven force on the cigarette butt incision during cutting, there are often situations where cigarettes are blocked during cutting, resulting in low equipment operation efficiency. When cleaning the blocked cigarettes, the entire channel needs to be disassembled, which is rather troublesome and inconvenient.

[0007] When the cigarette moves downward to the next process in the inclined channel, it only relies on the acceleration wheel of the previous process to provide the power for forward movement. The running speed of the cigarette gradually decays. The original device has low efficiency in processing defective pearl bursting cigarettes and cannot effectively and smoothly enter the next sorting process. Summary of the Invention

[0008] In order to overcome the problems existing in the background technology, the present invention can rotate the cigarette.

[0042] Embodiment 3

[0043] As Figures 1-9 As shown, the defective product bursting bead cigarette spiral cutting and accelerating device includes a base 1, a cigarette channel 2, a cigarette cutting mechanism 3, and a cigarette rotating mechanism 4. A cigarette channel 2 for conveying cigarettes is installed on the base 1. In this embodiment, the base 1 includes a bottom plate 101, a vertical plate 102, a support plate 103, and a cigarette channel 2 support column 104. A cigarette cutting mechanism 3 and a cigarette rotating mechanism 4 are also installed on the base 1. The cigarette cutting mechanism 3 is used for cutting cigarettes, and the cigarette rotating mechanism 4 is used for rotating the cigarettes while being cut. The cigarette cutting mechanism 3 and the cigarette rotating mechanism 4 are both detachably fixed on the moving plate 302, and the cigarette channel 2 passes through and is fixed on the cigarette channel 2 support columns 104 on both sides of the vertical plate 102.

[0044] At least one cutting slot 201 for a cigarette cutting mechanism 3 to extend into and contact and cut the internal cigarette is provided on the cigarette channel 2, and at least one notch for a cigarette rotating mechanism 4 to extend into and drive the cigarette to rotate. In this embodiment, a cutting slot 201, a left notch 202, and a right notch 203 are provided at the middle position of the cigarette channel 2. The above three slots are all inclined, and the inclination angles form a 6-degree angle with the axis of the cigarette entering the cigarette channel 2 respectively. The cutting slot 201 is located above the cigarette channel 2, and the left notch 202 and the right notch 203 are located on both sides of the cigarette channel 2, with opposite inclination directions.

[0045] A cigarette accelerating mechanism 6 for accelerating the conveyed cigarette is further installed on the cigarette channel 2. The cigarette accelerating mechanism 6 uses a gas source as the conveying power, and a negative pressure gas source or a positive pressure gas source can be selected. In this embodiment, the cigarette accelerating mechanism 6 includes a negative pressure generator 601. An air inlet 603 and an air outlet 604 are provided on the negative pressure generator 601. The air inlet 603 and the air outlet 604 are connected to an air compressor through a working pipeline. The negative pressure generator 601 is arranged at the tail end of the cigarette channel 2, and the negative pressure generator 601 is installed at the downstream position of the cutting slot 201 and the notch along the cigarette conveying direction, ensuring that the negative pressure position is close to the cutting and rotating positions, so that the cut cigarette can smoothly enter the next process for tobacco shred and paper flower sorting. In addition, the cigarette accelerating mechanism 6 in this embodiment further includes an accelerating pipeline 602 installed on the cigarette channel 2. At least one air nozzle 606 is inclined along the cigarette conveying direction on the accelerating pipeline 602. One air nozzle 606 is provided on each of the left and right sides along the accelerating pipeline 602. An accelerating air passage 605 is opened in the side accelerating pipeline 602. The accelerating air passage 605 communicates with the cigarette channel 2, and the accelerating air passage 605 is inclined, and the inclination direction forms a 25-30° angle with the running direction of the cigarette axis. The air nozzle 606 of the accelerating pipeline 602 is connected to a gas supply pipe, and the air inlet 603 and the air outlet 604 of the negative pressure generator 601 are respectively connected to the working pipeline. When the side accelerating pipeline 602 and the negative pressure generator 601 work, the cigarette starts to be accelerated forward by the airflow at different positions in the cigarette channel 2, reducing the probability of cigarette congestion, and at the same time improving the working efficiency of the whole set of devices for processing defective pearl cigarettes. The cut defective pearl cigarettes can enter the next process more smoothly.

[0046] Specifically, an acceleration pipeline 602 is installed at the upstream position of the cutting groove 201 and the notch along the cigarette conveying direction, and a negative pressure generator 601 is installed at the downstream position of the cutting groove 201 and the notch along the cigarette conveying direction. By installing the negative pressure generator 601 and the acceleration pipeline 602 in the upstream and downstream directions of the cutting groove 201 and the notch, acceleration of the cigarette can be obtained at both sides of cutting and rotation. During cutting, the high-pressure air in the side acceleration pipeline 602 further accelerates the cigarette and conveys it forward, improving the cutting quality. The negative pressure generated by the negative pressure generator 601 at the tail end of the cigarette channel 2 also accelerates the cigarette in the cigarette channel 2, enabling the cut cigarette to smoothly enter the next process for tobacco shred and paper flower sorting.

[0047] The cigarette cutting mechanism 3 includes a motor 301, an adjustable bracket, and a rotary cutter 303. The motor 301 is installed on the base 1 through the adjustable bracket, and a rotary cutter extending into the cutting groove 201 is installed on the output shaft of the motor 301. In this embodiment, it further includes a gland 304 and an axial pressing cover 305. The rotary cutter 303 is clamped in the middle by the gland 304. The gland 304 is fixed on the rotating shaft of the motor 301 through the axial pressing cover 305 using screws 311. The rotary cutter 303 extends into the cutting groove 201 opening of the cigarette channel 2. The rotational speed of the rotary cutter 303 of the cigarette cutting mechanism 3 is 3000 revolutions per minute, and the rotational speed of the rotating disk of the cigarette rotating mechanism 4 is 2800 revolutions per minute.

[0048] The cigarette rotating mechanism 4 includes a motor 301, an adjustable bracket, and a rotating disk. The motor 301 is installed on the base 1 through the adjustable bracket, and a rotating disk extending into the notch is installed on the output shaft of the motor 301. In this embodiment, the cigarette rotating mechanism 4 is divided into a left rotating mechanism and a right rotating mechanism. The structure of the cigarette rotating mechanism 4 is the same as that of the cigarette cutting mechanism 3, except that the rotary cutter 303 is replaced with a rotating disk, making most of the parts of the cigarette cutting mechanism 3 and the cigarette rotating mechanism 4 the same, which is convenient for repair and maintenance. In this embodiment, the rotating disk of the left cigarette rotating mechanism 4 rotates clockwise, and the rotating disk of the right cigarette rotating mechanism 4 rotates counterclockwise. The two disks rotate together to make the cigarette rotate counterclockwise along the axis while the cigarette is being cut in a straight line. The thickness of the left and right rotating disks is 3 mm, and the outer circular surface is a relatively rough working surface with fine patterns rolled on the working surface. After adjustment, there is a compression amount of 0.1 mm for the cigarette, making it easy for the cigarette to rotate in the required direction. The cutting groove 201, the left notch 202, and the right notch 203 are quadrilateral in shape. The width of the cutting groove 201 is 0.5 mm, the thickness of the rotary cutter 303 is 0.3 mm, the width of the left and right notches 203 is 3.2 mm, and the thickness of the left and right rotating disks is 3 mm.

[0049] The adjustable bracket includes a motor base 306, a moving plate 302, a fixed plate 307, and screws 311. The motor base 306 is fixedly connected to the base 1. Fixed plates 307 are symmetrically arranged on both sides of the motor base 306. The moving plate 302 for fixedly connecting with the motor 301 is slidably connected in the slideway formed by the two fixed plates 307. A countersunk kidney-shaped hole 308 is arranged on the fixed plate 307 along the sliding direction of the moving plate 302. The position of the countersunk kidney-shaped hole 308 is connected and fixed to the moving plate 302 by setting the screw 311. A horizontally arranged opening screw support 310 is installed on the motor base 306. A screw 309 slidably connected to the hole of the screw support 310 is installed on the moving plate 302. An adjusting nut 312 located on the screw support 310 is threadedly connected to the screw 309. In this embodiment, the motor 301 is fixed on the moving plate 302, the moving plate 302 is fixed on the fixed plate 307, the fixed plate 307 is fixed on the vertical plate 102, the screw support 310 is fixed on the fixed plate 307 by the screw 311, the bottom of the screw 309 is connected to the moving plate 302 by thread, the screw 309 passes through the hole on the screw support 310 and is connected to the moving plate 302, and an adjusting nut 312 is installed at the top of the screw support 310. Loosen the screw 311 in the kidney-shaped hole on the fixed plate 307, and the connection between the fixed plate 307 and the moving plate 302 is released. Rotating the adjusting nut 312 on the screw 309 can control the up and down movement of the moving plate 302, so that the motor 301 can move up and down following the moving plate 302 for adjustment, that is, the feed amount of the rotary cutter 303 in the cutting groove 201 can be adjusted respectively, the compression amount of the left rotary disc on the cigarette in the left slot 202, and the compression amount of the right rotary disc on the cigarette in the right slot 203.

[0050] The cigarettes transferred by the accelerating wheel in the previous process enter the cigarette channel 2 from the entrance of the cigarette channel 2. The cigarettes are moving in a straight line. When passing through the left and right cigarette rotating mechanisms 4 on the left and right sides, the two rotating discs respectively give the cigarettes a downward and an upward force in the vertical direction. The two forces form a couple, so that the cigarettes rotate counterclockwise along the cigarette axis while being cut in a straight line. After being cut by the rotary cutter 303 of the upper cigarette cutting mechanism 3, a curved cutting line is formed. The cigarette paper and tipping paper wrapping the whole cigarette are cut into a whole piece of complete auxiliary material, and the 1-mm glue-free area at the cigarette paper lap 502 of the cigarette will not be cut into fine paper scraps. At the same time of cutting, the high-pressure air in the side accelerating pipeline 602 further accelerates the cigarettes forward for conveying, improving the cutting quality. The negative pressure generated by the negative pressure generator 601 at the end of the cigarette channel 2 also accelerates the cigarettes in the cigarette channel 2, so that the cut cigarettes can smoothly enter the next process for tobacco and paper flower sorting.

[0051] The present invention can rotate the cigarette rod, and the rotated cigarette rod can be cut more completely, eliminating the occurrence of fine paper scraps in the cigarette paper at the non-glued area of the cigarette rod joint, improving the purity of the recycled tobacco, greatly reducing the occurrence of cigarette rod congestion, and being more convenient for equipment maintenance and cleaning. In addition, the cigarette rod can be accelerated during the cutting process, better ensuring the cutting effect, so that the cut cigarette rod can enter the next process more smoothly for separating the tobacco and paper scraps; compared with the double circular knife cutting, the single circular knife spiral cutting method of the present device improves the cutting effect while reducing the loss of the circular knife. Since the rotation speed of the circular knife is reduced, the service life of each part of the entire cutting mechanism is prolonged.

[0052] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
