Description

Technical Field

[0001] This application relates to the field of cigarette production technology, and more specifically, to a cleaning device for a cigarette machine that sucks up a cigarette ribbon. Background Technology

[0002] The tobacco suction belt is a key component in cigarette rolling machines for forming the tobacco strands. It's a conveyor belt made of woven nylon filaments with regularly spaced mesh on its surface. During cigarette production, the tobacco strands are drawn onto the suction belt under negative pressure, forming a uniform bundle. Currently, mainstream cigarette rolling machines such as ZJ17, ZJ112, ZJ116, ZJ118, ZJ119, PROTOS-M5, and PROTOS-M8 all use this suction belt to transport the tobacco strands.

[0003] However, due to the lack of a cleaning device for the suction ribbon in existing cigarette rolling machines, tobacco residue will remain on the surface of the suction ribbon after a period of use. This tobacco residue will block the mesh of the suction ribbon, thereby affecting the suction and forming effect, resulting in quality defects such as empty cigarette ends and unstable cigarette weight.

[0023] This application provides a cleaning device for cigarette machine suction ribbons; please refer to [link / reference]. Figures 1 to 4 An exemplary description is provided for a cleaning device that sucks up the cigarette paper in a cigarette machine: like Figure 1 and Figure 2 As shown, the cleaning device includes: a vacuum base 1 and a cleaning component 2 connected to the vacuum base 1. A vacuum groove 3 is provided on the first surface of the vacuum base 1, and a negative pressure channel is provided on the second surface of the vacuum base 1. The first surface and the second surface are perpendicular to each other. The negative pressure channel is connected to the vacuum groove 3. The cleaning component 2 is provided with a brush 7. The bristles of the brush 7 extend perpendicularly to the groove opening plane of the vacuum groove 3. When the cleaning device is working, the suction ribbon 10 is placed between the vacuum groove 3 and the brush 7, and the running direction of the suction ribbon 10 is parallel to the length direction of the vacuum groove 3.

[0024] Here, the vacuum cleaner base 1 is the basic component of the cleaning device, used to support the vacuuming-related structures and connect with other components, providing a stable installation and working platform for the entire cleaning device. Its material can be a wear-resistant and corrosion-resistant metal, such as stainless steel, to ensure its service life under long-term contact with tobacco and other substances, as well as negative pressure environments. For example, the shape of the vacuum cleaner base 1 can be designed according to the installation space of the cigarette machine, generally in a rectangular shape, to facilitate processing and installation.

[0025] The cleaning component 2 is used to clean the surface of the suction ribbon 10. Its brush 7 contacts the suction ribbon 10, sweeping away impurities such as tobacco residue. Combined with the suction action of the vacuum chamber 3, this achieves a thorough cleaning of the suction ribbon 10. The connection between the cleaning component 2 and the vacuum base 1 needs to be secure and easily adjustable to ensure that the brush 7 maintains appropriate contact pressure with the suction ribbon 10 at all times.

[0026] In an alternative embodiment, the cleaning component 2 can be designed as a plate-like structure that matches the vacuum cleaner base 1, which saves space and facilitates installation and adjustment. For example, the cleaning component 2 can be made of the same metal material as the vacuum cleaner base 1, with the same length as the vacuum cleaner base 1, and its width determined according to the arrangement of the brushes 7 to ensure sufficient space for installing multiple sets of brushes 7. Specifically, the suction groove 3 is a recessed structure formed on the first surface of the suction base 1. Under negative pressure, it can suck in impurities such as tobacco scraps swept off the suction ribbon 10, preventing the impurities from re-adhering to the suction ribbon 10. The shape and size of the suction groove 3 can be designed according to the width of the suction ribbon 10 and the operating conditions to ensure the suction effect. For example, the suction groove 3 can be designed as a long, narrow groove, with a width slightly larger than the width of the suction ribbon 10. This ensures that impurities on the suction ribbon 10 can be effectively sucked into the suction groove 3. For instance, when the width of the suction ribbon 10 is 9.2 mm, the opening width of the suction groove 3 can be set to 10.2 mm; when the width of the suction ribbon 10 is 7.2 mm, the opening width of the suction groove 3 can be set to 8 mm. With the above settings, it can be ensured that impurities on the surface of the suction ribbon 10 can be covered by the suction groove 3 during operation.

[0027] The negative pressure channel is a channel structure located on the second surface of the vacuum cleaner base 1. It is connected to the vacuum cleaner groove 3 and is used to introduce an external negative pressure source into the vacuum cleaner groove 3, thereby generating negative pressure within the vacuum cleaner groove 3 and achieving the vacuuming function. The shape and size of the negative pressure channel can be designed according to the size of the vacuum cleaner groove 3 and the required negative pressure intensity.

[0028] For example, the negative pressure channel can be designed as a groove structure perpendicular to the suction groove 3, with one end connected to the suction groove 3 and the other end connected to an external negative pressure source through a pipe. For example, the cross-section of the negative pressure channel can be rectangular, and its width and depth can be determined according to the required negative pressure flow rate. For example, the width can be 10mm and the depth can be 15mm to ensure that sufficient negative pressure enters the suction groove 3. The brush 7 is a component on the cleaning part 2 that directly contacts and cleans the surface of the suction ribbon 10. Its bristles extend perpendicularly to the plane of the suction groove 3, ensuring good contact between the bristles and the surface of the suction ribbon 10, thus effectively cleaning impurities from the suction ribbon 10. The brush 7 can be made of a soft and elastic material to avoid damaging the surface of the suction ribbon 10. In an optional embodiment, the brush 7 can be made of nylon, which has good abrasion resistance and elasticity, and can maintain good cleaning performance during long-term use. The length of the brush 7 needs to be adjusted according to the distance between the suction ribbon 10 and the cleaning component 2 to ensure that the bristles can make close contact with the surface of the suction ribbon 10. For example, the length of the brush 7 can be set to 20mm, so that when the cleaning component 2 is installed, the bristles can be slightly bent to maintain appropriate contact force with the surface of the suction ribbon 10.

[0029] In one optional embodiment, when the vacuuming groove 3 is formed on the vacuuming base 1, a first groove edge 11 and a second groove edge 12 are formed. The first groove edge 11 and the second groove edge 12 are along the length direction of the vacuuming groove 3. The height of the first groove edge 11 is higher than the height of the second groove edge 12. An installation hole 13 is provided on the first groove edge 11 for installing the cleaning component 2. The first groove edge 11 is the edge portion located on one side of the suction groove 3 formed when the suction groove 3 is opened on the suction base 1. Its height is higher than the second groove edge 12. It is mainly used to install the cleaning component 2, providing a stable installation base for the cleaning component 2. The height of the first groove edge 11 can be designed according to the installation position of the cleaning component 2 and the distance between the brush 7 and the suction ribbon 10. The second groove edge 12 is the edge portion located on the other side of the suction groove 3 formed when the suction groove 3 is opened on the suction base 1. Its height is lower than the first groove edge 11. Together with the first groove edge 11, it forms the two sides of the suction groove 3, providing a certain degree of support and shaping for the suction groove 3. The height of the second groove edge 12 can be designed according to the depth of the suction groove 3 and the operation of the suction ribbon 10. For example, the height of the first groove 11 can be set to 40mm, which provides sufficient space for the installation of the cleaning component 2 while ensuring that the brush 7 on the cleaning component 2 maintains a suitable distance from the surface of the suction ribbon 10. The width of the first groove 11 can be determined according to the installation dimensions of the cleaning component 2, generally 20mm, to ensure that the cleaning component 2 can be securely installed. For example, mounting holes 13 can be provided on the first groove 11, and the cleaning component 2 can be fixed thereon by bolts or other connectors. The height of the second groove 12 can be set to 5mm, which ensures that the vacuuming groove 3 has sufficient depth without affecting the normal operation of the suction ribbon 10. The width of the second groove 12 is the same as that of the first groove 11, generally 20mm, to ensure the structural stability of the vacuuming base 1. For example, the distance between the second groove 12 and the first groove 11 is the width of the opening of the vacuuming groove 3. When the width of the suction ribbon 10 is 9.2mm, this distance can be set to 10.2mm. The mounting holes 13 are perforated structures formed on the first groove edge 11. They are used to position and fix the cleaning component 2 during installation, ensuring that the cleaning component 2 can be accurately installed in the predetermined position and that the relative position between the brush 7 and the suction ribbon 10 is correct. The number and size of the mounting holes 13 can be designed according to the installation requirements of the cleaning component 2. For example, mounting holes 13 can be two M5 threaded holes, located at both ends of the first groove edge 11, so that the cleaning component 2 can be firmly fixed to the first groove edge 11 by bolts or other connecting parts. For example, the distance between the two mounting holes 13 can be determined according to the length of the cleaning component 2. When the length of the cleaning component 2 is 100mm, the distance between the two mounting holes 13 can be set to 80mm to ensure the stability of the installation of the cleaning component 2.

[0030] Furthermore, such as Figure 3 and Figure 4 As shown, a first groove 14 is provided on the surface of the opening of the dust collection groove 3. The length direction of the first groove 14 is parallel to the length direction of the dust collection groove 3. The width of the first groove 14 is smaller than the width of the suction ribbon 10, and the width of the suction ribbon 10 is smaller than the width of the opening of the dust collection groove 3.

[0031] The first groove 14 is a groove structure formed on the surface of the suction groove 3 opening. Its length direction is parallel to the length direction of the suction groove 3. Its main function is to further enhance the adsorption effect of the suction groove 3 on the suction ribbon 10 and prevent impurities from accumulating on the surface of the suction groove 3 opening. The width of the first groove 14 is smaller than the width of the suction ribbon 10. This ensures that during operation, the edge of the suction ribbon 10 can cover the first groove 14, preventing impurities from leaking out from the edge of the suction ribbon 10.

[0032] For example, the width of the first groove 14 can be determined based on the width of the suction ribbon 10, generally about 20% smaller. For instance, when the width of the suction ribbon 10 is 9.2mm, the width of the first groove 14 can be set to 7.4mm; when the width of the suction ribbon 10 is 7.2mm, the width of the first groove 14 can be set to 5.8mm. This ensures that the suction ribbon 10 can cover the first groove 14 while also generating a stronger negative pressure within the first groove 14, thus enhancing the suction effect. The depth of the first groove 14 can be set to 8mm to ensure sufficient space to accommodate the sucked-in impurities.

[0033] Furthermore, such as Figure 3 and Figure 4 As shown, a second groove 4 is provided on the second surface of the vacuum cleaner seat 1. The second groove 4 is connected to the first groove 14 to form a negative pressure channel, so that when the second groove 4 is connected to negative pressure, it provides dust removal negative pressure to the vacuum cleaner 3 through the negative pressure channel.

[0034] The second groove 4 is a groove structure formed on the second surface of the vacuum cleaner base 1. It communicates with the first groove 14 to form a negative pressure channel, which is an important channel for negative pressure to enter the vacuum cleaner slot 3. The shape and size of the second groove 4 can be adapted to the first groove 14 to ensure that negative pressure can smoothly enter the vacuum cleaner slot 3.

[0035] Specifically, the depth direction of the second groove 4 is perpendicular to the depth direction of the first groove 14, and the opening size of the second groove 4 is the same as the opening size of the dust collection groove 3.

[0036] Here, the fact that the depth direction of the second groove 4 is perpendicular to the depth direction of the first groove 14 means that the opening direction of the second groove 4 is perpendicular to the opening direction of the first groove 14. This allows the negative pressure channel to form a right-angle turn, which is convenient for arranging the negative pressure channel on the vacuum cleaner seat 1, and also ensures the smooth flow of negative pressure in the channel.

[0037] In other words, the first groove 14 is formed along the height of the vacuum cleaner base 1, while the second groove 4 is formed along the length of the vacuum cleaner base 1. The two are perpendicular to each other, forming an L-shaped negative pressure channel. For example, the depth direction of the first groove 14 is downward from the opening plane of the vacuum cleaner groove 3, while the depth direction of the second groove 4 is inward from the side of the vacuum cleaner base 1. The two are connected inside the vacuum cleaner base 1. This design can make full use of the space of the vacuum cleaner base 1, making the structure more compact.

[0038] The opening size of the second groove 4 is the same as that of the dust collection groove 3. That is, the length and width of the second groove 4 are the same as those of the dust collection groove 3. This ensures that the negative pressure can be evenly distributed into all parts of the dust collection groove 3, thereby improving the uniformity of the dust collection effect.

[0039] For example, when the length of the suction groove 3 is 100mm and the width is 10.2mm, the length of the second groove 4 is also set to 100mm and the width to 10.2mm, so as to ensure that the negative pressure can fully cover the suction groove 3, so that the negative pressure intensity at each position in the suction groove 3 is consistent, thereby ensuring that the impurities on the suction ribbon 10 can be evenly sucked into the suction groove 3.

[0040] In one optional embodiment, a first elongated hole 5 is provided on the third surface of the vacuum cleaner seat 1, the third surface is parallel to the second surface, and the length direction of the first elongated hole 5 is perpendicular to the length direction of the vacuum cleaner groove 3; the cleaning device also includes a first connector 6, which passes through the first elongated hole 5 to position the vacuum cleaner seat 1.

[0041] The first elongated hole 5 is a long, narrow hole structure formed on the third surface of the vacuum cleaner base 1. Its length direction is perpendicular to the length direction of the vacuum cleaner groove 3. It is mainly used to adjust the position of the vacuum cleaner base 1 so as to adjust the distance between the vacuum cleaner groove 3 and the suction ribbon 10 according to the actual situation, thereby ensuring the vacuuming effect. The size of the first elongated hole 5 can be designed according to the adjustment range of the vacuum cleaner base 1. Specifically, the length of the first elongated hole 5 can be set to 30mm and the width can be set to 6mm, which provides sufficient adjustment space for the vacuum cleaner base 1. For example, when it is necessary to adjust the distance between the vacuum cleaner groove 3 and the vacuum cleaner ribbon 10, the first connecting piece 6 can be loosened, and the vacuum cleaner base 1 can be moved along the length direction of the first elongated hole 5. After adjusting to the appropriate position, the first connecting piece 6 can be tightened to fix the vacuum cleaner base 1.

[0042] Optionally, the first connector 6 is used to position and fix the vacuum cleaner base 1 through the first elongated hole 5, and it can be a fastener such as a bolt or screw. The size of the first connector 6 needs to be adapted to the size of the first elongated hole 5 to ensure that the vacuum cleaner base 1 can be effectively fixed.

[0043] For example, the first connector 6 can be made of an M5×30 bolt, the diameter of which matches the width of the first elongated hole 5, and the length of which ensures that it can be firmly connected to the mounting base on the cigarette machine after passing through the first elongated hole 5. For example, after the bolt is passed through the first elongated hole 5, it is screwed into the threaded hole on the mounting base. By tightening the bolt, the dust collection seat 1 is firmly fixed to the mounting base, preventing the dust collection seat 1 from moving during operation.

[0044] In one optional embodiment, the cleaning component 2 includes a mounting block and multiple sets of brushes 7 disposed on the mounting block. The mounting block is connected to a first groove 11 on the vacuum seat 1, and the multiple sets of brushes 7 are distributed along the length direction of the vacuum groove 3.

[0045] The mounting block is the main part of the cleaning component 2, used to mount the brush 7 and connect it to the first groove 11 on the vacuum cleaner base 1, providing stable support for the brush 7. The mounting block can be made of the same metal material as the vacuum cleaner base 1 to ensure its structural strength and durability. Here, the mounting block can be designed as a cuboid, with its length matching that of the vacuum cleaner base 1, and its width determined according to the arrangement of the brushes 7. For example, the mounting block can be 100mm long, 20mm wide, and 10mm thick, which ensures sufficient space for installing multiple sets of brushes 7 while also providing a secure connection to the first groove edge 11.

[0046] The multiple sets of brushes 7 are mounted on the mounting block and distributed along the length of the suction groove 3. Their function is to clean the surface of the suction ribbon 10 from multiple positions, thereby improving the cleaning effect. The number and spacing of the multiple sets of brushes 7 can be designed according to the width of the suction ribbon 10 and the cleaning requirements.

[0047] For example, four sets of brushes 7 can be set up and evenly distributed along the length of the suction groove 3, with a spacing of 20mm between each set of brushes 7. For instance, when the length of the suction groove 3 is 100mm, the four sets of brushes 7 are installed at positions of 0mm, 25mm, 50mm, and 75mm on the mounting block, respectively. This ensures that all parts of the surface of the suction ribbon 10 can be cleaned by the brushes 7 during operation, improving the comprehensiveness of cleaning.

[0048] In one optional embodiment, the working end of the brush 7 is conical, the diameter of the cross-sectional area of ​​the end face of the cone at the point where the brush 7 contacts the upper surface of the absorbent ribbon 10 is larger than the mesh diameter of the absorbent ribbon 10, and / or the hardness of the brush 7 is less than the hardness of the absorbent ribbon 10.

[0049] The conical shape of the working end of the brush 7 refers to the cone-shaped end of the brush 7 that contacts the suction ribbon 10. This design allows for more uniform contact between the brush 7 and the surface of the suction ribbon 10, while also enhancing the cleaning effect on impurities within the mesh of the suction ribbon 10. The shape of the cone can be designed according to the surface shape of the suction ribbon 10 and the cleaning requirements.

[0050] Here, the diameter of the conical tail end face that contacts the upper surface of the suction ribbon 10 is larger than the diameter of the mesh of the suction ribbon 10 to ensure that the brush 7 can effectively clean the mesh of the suction ribbon 10 and remove impurities from the mesh. If the diameter of the end face is smaller than the diameter of the mesh, it may not be able to completely cover the mesh, resulting in incomplete cleaning.

[0051] For example, if the mesh diameter of the suction ribbon 10 is generally 0.5mm, then the diameter of the cross-sectional area of ​​the conical tail can be set to 1mm. This way, when the brush 7 contacts the suction ribbon 10, its tail can cover the mesh, and the elasticity of the bristles will sweep out impurities from the mesh. For instance, during the operation of the suction ribbon 10, the conical tail of the brush 7 continuously contacts and rubs against the surface of the suction ribbon 10, causing impurities such as tobacco shreds to be carried out from the mesh, thus achieving the purpose of cleaning the mesh. Furthermore, the hardness of the brush 7 is less than that of the suction ribbon 10 to avoid damaging the surface of the suction ribbon 10 during the cleaning process and to protect its service life. The suction ribbon 10 is generally made of a relatively hard material, possessing a certain degree of hardness and abrasion resistance. The brush 7 can be made of a nylon material with lower hardness, typically 20%-30% lower than the hardness of the suction ribbon 10. For example, if the suction ribbon 10 has a Shore hardness of 80, then the brush 7 can be made of a nylon material with a Shore hardness of around 60. This way, during the cleaning process, the brush 7 can effectively remove impurities without scratching or abrading the surface of the suction ribbon 10.

[0052] In one optional embodiment, a second elongated hole 8 is provided on the mounting block, wherein the plane on which the second elongated hole 8 is provided is parallel to the second surface of the vacuum seat 1, and the length direction of the second elongated hole 8 is parallel to the extension direction of the bristles of the brush 7; the cleaning device also includes a second connector 9, which passes through the second elongated hole 8 to position the cleaning component 2. The second elongated hole 8 is a long strip-shaped hole structure opened on the mounting block. Its opening plane is parallel to the second surface of the vacuum seat 1, and its length direction is parallel to the extension direction of the bristles of the brush 7. It is mainly used to adjust the position of the cleaning component 2 so as to adjust the distance between the brush 7 and the suction ribbon 10 according to the actual situation, and ensure that the brush 7 can maintain a suitable contact force with the surface of the suction ribbon 10. Here, the length of the second elongated hole 8 can be set to 20mm and the width to 6mm, which provides sufficient adjustment space for the cleaning component 2. For example, when it is necessary to adjust the distance between the brush 7 and the suction ribbon 10, the second connector 9 can be loosened, and the cleaning component 2 can be moved along the length of the second elongated hole 8. After adjusting to the appropriate position, the second connector 9 can be tightened to fix the cleaning component 2 in place. The second connector 9 is a component used to position and fix the cleaning component 2 through the second elongated hole 8. Its function is similar to that of the first connector 6, but its size and specifications can be selected according to the weight of the cleaning component 2 and the installation requirements.

[0053] The embodiments of this application have a simple structure, are easy to use, and can clean the suction ribbon online. They have a dust-collecting effect on the suction ribbon, thereby solving the problems of empty cigarette ends and unstable cigarette weight caused by mesh blockage in the suction ribbon in the prior art.
