Description

TECHNICAL FIELD

[0001] The present application relates to the field of cigarette processing, in particular to a filter tip attaching machine residual cigarette paper sheet separation tank. BACKGROUND

[0002] In the production process of the ZJ17 filter tip attaching machine, the suction force of the negative pressure generated by the suction device negative pressure generator can smoothly suck all the paper sheets through the pipeline and then discharge them. The discharged tipping paper sheets can be stored in two ways. One way is to be directly discharged into the waste cigarette barrel, but the positive pressure blowing of the paper discharge port can blow the paper sheets in the waste bin and cause the tipping paper sheets and tobacco dust to fly around, resulting in frequent occurrence of defective cigarettes such as double tipping paper cigarettes. The other way is to be discharged into the paper sheet collection tank at the rear of the machine through the pipeline. The paper sheet collection tank can prevent the accumulation of paper sheets in the drum groove and thus prevent the formation of double tipping paper defective cigarettes.

[0003] The tipping paper sheet collection tank is installed in the rear of the YJ27 filter tip attaching machine without a separate motor and fan. However, due to the need to install a fan and a motor in the rear of the YJ27 filter tip attaching machine, the original space for installing the tipping paper sheet collection tank is occupied, so the tipping paper sheet collection tank has to be removed.

[0004] The main function of the tipping paper suction device is to remove the paper sheets discharged from the tipping paper drum to prevent the accumulated tipping paper sheets from being adsorbed on the surface of the drum and then being stuck on the cigarettes, thereby causing defective cigarettes. Therefore, after the tipping paper suction device completes the tipping paper conveying, the tipping paper sheets must be collected and then removed. Therefore, the design of the paper sheet collection tank is very important. If the tipping paper sheet collection tank is not installed, the positive pressure blowing of the paper discharge port of the tipping paper suction device can blow the paper sheets in the waste bin and cause the tipping paper sheets and tobacco dust to fly around, resulting in frequent occurrence of defective cigarettes such as double tipping paper cigarettes. When the air pressure supplied by the negative pressure generator is reduced, the negative pressure suction force of the paper conveying pipeline can be insufficient, although the positive pressure blowing of the paper discharge port is reduced, but the tipping paper sheets can be accumulated at the inlet of the pipeline, the paper sheets can block the outlet of the pipeline and the collector, and other problems can occur. Such problems can occur more than 60 times a day, and double tipping paper defective cigarettes can flow into the next process, which can seriously affect the effective guarantee of product quality.

[0005] Therefore, the research direction is to concentrate the collection, uniformly store the tipping paper sheets, reduce the flying of the paper sheets and tobacco dust, and reduce the occurrence of defective cigarettes with double tipping paper. SUMMARY

[0006] To solve the above problems, the present application provides a filter tip attaching machine residual cigarette paper sheet separation tank to concentrate the collection of tipping paper sheets and residual cigarettes.

[0007] The technical scheme adopted by the present application to solve the technical problems is that:

[0008] A separator for residual cigarette paper in a filter nozzle dispenser includes an upward-opening box, a pull-out upward-opening residual cigarette collection box located at the lower left of the box, and a pull-out tipping paper collection box located at the lower right of the box.

[0009] An isolation plate is provided between the residual smoke collection box and the tipping paper collection box. A smoke guide plate is provided above the tipping paper collection box. The upper end of the smoke guide plate is inclined to the left. The right end of the smoke guide plate is connected to the right side wall of the box body, and its left end extends to the side of the residual smoke collection box. The residual smoke slides down the smoke guide plate into the residual smoke collection box.

[0010] The smoke guide plate is provided with a paper input pipe that extends into the cork paper collection box;

[0011] A gap is left between the top of the isolation plate and the smoke guide plate;

[0012] The wall of the cork paper collection box is provided with pressure relief holes evenly distributed. After the airflow in the cork paper collection box passes through the pressure relief holes, it is then buffered and discharged from the gap between the support plate and the smoke guide plate.

[0013] Furthermore, insertion ports are provided on the left and right sides of the lower part of the front side wall of the box, and the cigarette residue collection box and the tipping paper scrap collection box are respectively inserted into the box through the insertion ports. The front end of the cigarette residue collection box and the tipping paper scrap collection box are respectively provided with handles.

[0014] Furthermore, a support plate is provided on the upper right side of the isolation plate, which is connected to the front and rear walls of the box. A gap is left between the support plate and the isolation plate. The right end of the smoke guide plate is connected to the top of the right side wall of the box, and its left end extends to the side of the residual smoke collection box through the support plate.

[0015] Furthermore, the paper input pipe includes an "L"-shaped paper receiving pipe located inside the cork paper collection box. The paper receiving pipe includes interconnected vertical pipe sections and horizontal pipe sections, and the vertical pipe sections have an inverted conical structure.

[0016] Furthermore, the top wall and left and right side walls of the cork paper collection box are evenly provided with pressure relief holes arranged in an array, and the pressure relief holes are also provided on the pipe wall of the horizontal pipe section.

[0017] Furthermore, the wall of the cork paper collection box is provided with dustproof cotton covering the pressure relief hole.

[0018] Furthermore, the rear side wall of the cork paper collection box is configured as an openable rear cover.

[0019] Furthermore, the rear end of the top wall of the cork paper collection box is connected to the top of its rear cover by a hinge, and the rear cover is opened by folding upwards through the hinge.

[0020] Furthermore, the smoke guide slide is set at a 50-degree angle to the right side wall of the cork paper collection box.

[0021] Furthermore, a support is provided at the bottom of the box.

[0022] The beneficial effects of this invention are as follows:

[0023] This application designs a separation box for residual cigarette paper in a filter nozzle filling machine, which has the combined functions of collecting residual cigarettes and collecting paper. The tipping paper paper, which is transported through the tipping paper conveying pipe, is discharged into the tipping paper paper collection box through the paper paper input pipe. Meanwhile, cigarettes that fall off the drum and defective cigarettes that clog the rubbing plate are guided into the residual cigarette collection box by the guide slide. At the same time, the airflow in the tipping paper paper collection box is prevented from flying smoke droplets by the dustproof cotton, and the pressure is released through the pressure relief hole. After being buffered by the gap between the support plate and the isolation plate, it is discharged to avoid the flying of smoke dust.

[0024] The separation box of this application not only realizes the function of centralized collection of residual tobacco and tipping paper, but also ensures normal production, improves the quality of cigarettes, and reduces the labor intensity of operators. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In the description of this invention, it should be understood that the terms "upper side", "lower side", "upper end", "both ends", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] In this invention, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," "link," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Reference Figures 1-8 This embodiment provides a separator for residual cigarette paper in a filter tip dispenser, including a box body 1 with the opening facing upwards, and a separator located at the lower left of the box body 1 (as shown in the image). Figure 1 The handle has an upward-opening pull-out residual smoke collection box 2 (direction determined by the main view) and a pull-out cork paper collection box 3 located on the lower right side of the box body 1.

[0039] Determining the installation location of the separator: Due to space constraints within the rear of the filter tipping machine, the installation of the tipping paper collection box 3 is limited; external installation would affect the aesthetics and neatness of the equipment. Therefore, the separator is positioned at the original residual smoke collection box 2 at the bottom of the filter tipping machine. Since the negative pressure tipping paper transmission pipe is located above the original residual smoke collection box 2 on the far right, to maintain the integrity of the equipment structure, the original residual smoke collection box 2 at the bottom of the filter tipping machine is removed. The original residual smoke collection box 2 is then used as the installation location for the separator. The external dimensions of the separator are determined to be the same as those of the original residual smoke collection box 2, i.e., the external dimensions of the box body 1 are 460mm long, 370mm wide, and 390mm high. The dimensions of the residual smoke collection box 2 are 455mm long, 170mm wide, and 260mm high.

[0040] A support 5 is provided at the bottom of the box body 1. An insertion port 9 is provided on the left and right sides of the lower part of the front side wall of the box body 1. The cigarette residue collection box 2 is inserted into the box body 1 through the left insertion port 9, and the tipping paper scrap collection box 3 is inserted into the box body 1 through the right insertion port 9. The front end of the cigarette residue collection box 2 and the tipping paper scrap collection box 3 are respectively provided with handles 6 to facilitate the pulling out of the cigarette residue collection box 2 and the tipping paper scrap collection box 3.

[0041] A vertical partition 7 is installed between the cigarette residue collection box 2 and the tipping paper scrap collection box 3, separating the cigarette residue collection box 2 and the tipping paper scrap collection box 3 on the left and right sides of the box body 1. A support plate 8 is installed on the upper right side of the partition plate 7, which is connected to the front and rear walls of the box body 1, and a 10mm gap is left between the support plate 8 and the partition plate 7.

[0042] A smoke guide slide 4 is installed above the tipping paper scrap collection box 3. The smoke guide slide 4 is 453mm long and has a height difference of 170mm. Its upper surface is inclined to the left. The right end of the smoke guide slide 4 is connected to the top of the right side wall of the box body 1, and its left end is positioned by the support plate 8 and extends to the side of the residual smoke collection box 2. The residual smoke falls onto the smoke guide slide 4 and slides down the smoke guide slide 4 into the residual smoke collection box 2.

[0043] Among them, the calculation and analysis of the tilt angle design of the smoke guide plate:

[0044] See Figure 4 The mechanical model of a cigarette sliding down the guide plate can be simplified to: Figure 5 Let the mass of the cigarette be m, the local gravitational acceleration be g, the tilt angle of the cigarette guide plate be α, and f be the frictional force acting on the cigarette. N The cigarette is supported by the guide plate, and the coefficient of kinetic friction of the inclined plane is μ.

[0045] In order to ensure that cigarettes can slide smoothly into the cigarette residue collection box, it is necessary to design the tilt angle of the cigarette guide slide to prevent the cigarettes from getting stuck on the slide due to friction and thus affecting production activities.

[0046] The force analysis of the cigarette is now performed:

[0047] Assuming the cigarette is stationary on the smoke guide plate, according to the equilibrium condition:

[0048] Decomposing the weight of the cigarette, mg, along directions parallel and perpendicular to the inclined plane, we get:

[0049] mgcosα=f

[0050] mgsinα=F N

[0051] Where f is the static friction force. Roughly assuming the maximum static friction force f′ of the cigarette guide plate is equal to the sliding friction force f, the critical condition for the cigarette to slide at this point is:

[0052] mgcosα=f′=μF N =μmgsinα

[0053] Transforming the above equation, we get:

[0054]

[0055] That is, the coefficient of kinetic friction μ is equal to the cotangent of the smoke guide plate angle.

[0056] To ensure that cigarettes can smoothly enter the collection box and achieve a good sliding effect, the following must be met:

[0057] mgcosα≥μmgsinα, i.e., μ≤cotα

[0058] According to the production data, the material of the smoke guide plate is steel, and the coefficient of dynamic friction μ is taken as 0.6.

[0059] so:

[0060] μ=0.6≤cotα

[0061] α≤arccot0.6=59.04°

[0062] Therefore, the inclination angle α of the smoke guide plate should be less than or equal to 59.04° to ensure that no cigarettes remain on the smoke guide plate and that the cigarettes slide off effectively. Considering the rationality of the spatial layout of the separation device, α of 50° is most suitable, as this angle provides good guidance for cigarettes to slide off and prevents cigarette residue.

[0063] The smoke guide slide 4 is equipped with a paper feed pipe 41 extending into the tipping paper collection box 3. The paper feed pipe 41 includes an "L"-shaped paper receiving pipe 33 located inside the tipping paper collection box 3. The paper receiving pipe 33 includes a vertical pipe section 331 and a horizontal pipe section 332 connected to each other. The vertical pipe section 331 has an inverted conical structure, which improves the downward guiding function of the vertical pipe section 331 in guiding the tipping paper. The pressure relief holes 32 on the wall of the horizontal pipe section 332 are arranged horizontally in a row, which is conducive to rapid venting and smoother paper feeding.

[0064] The top wall and left and right side walls of the cork paper collection box 3 are evenly provided with pressure relief holes 32 arranged in a row. The airflow in the cork paper collection box 3 is guided and depressurized through the pressure relief holes 32, and then discharged after being buffered through the gap between the support plate 8 and the isolation plate 7 to prevent dust from flying.

[0065] The inner wall of the tipping paper collection box 3, which has a pressure relief hole 32, is provided with dustproof cotton. Its function is to guide and relieve the airflow inside the tipping paper collection box 3 through the pressure relief hole 32, while blocking the leakage of tobacco dust inside the paper collection box, and preventing the flying tobacco dust from being rolled into the cigarette to form a cigarette with dust.

[0066] The rear end of the top wall of the tipping paper collection box 3 is connected to the top of its rear cover by a hinge 31. The rear cover is opened by folding upwards through the hinge 31, and the tipping paper in the tipping paper collection box 3 is taken out by opening the rear cover.

[0067] The operation procedure for the separator box for the residual cigarette paper in this filter is as follows:

[0068] Step 1: Install the filter tip receiving machine's residual cigarette paper separator.

[0069] The residual smoke collection box 2 is inserted into the box body 1 through the left insertion port 9, and the tipping paper collection box 3 is inserted into the box body 1 through the right insertion port 9. The smoke guide plate 4 is installed above the tipping paper collection box 3, with its upper end facing to the left. Then the entire separation box is installed in the original position of the residual smoke collection box 2.

[0070] Connect the paper input pipe 41 to the negative pressure water-tight paper transfer pipe of the filter nozzle assembly machine.

[0071] Step 2: Collect the remaining tobacco and cork paper scraps.

[0072] Cigarettes that fall from the drum of the filter nozzle receiving machine and defective cigarettes that clog the washboard are guided into the residual cigarette collection box 2 through the smoke guide slide plate 4;

[0073] The tipping paper sheets transported through the negative pressure tipping paper conveying pipe in step one are collected and discharged into the tipping paper sheet collection box 3 through the paper sheet input pipe 41. The airflow in the tipping paper sheet collection box 3 is guided and depressurized through the pressure relief hole, and then discharged after being buffered through the gap between the support plate 8 and the isolation plate 7.

[0074] Step 3: Remove the remaining tobacco and the piece of tipping paper.

[0075] Pull out the residual smoke collection box 2 and remove the residual smoke from its upward-facing opening;

[0076] Pull out the tipping paper collection box 3, open the back cover, and take out the tipping paper pieces from the back cover.

[0077] It should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
