Description

Technical Field

[0001] This utility model relates to the field of cigarette manufacturing technology, specifically to a device for removing cigarette waste from cigarette tow. Background Technology

[0002] In the production process of cigarette filter rod forming equipment, the opening machine is a crucial step. It loosens the tightly wound filaments, making them more dispersed and evenly distributed, thus preparing the filter rods for subsequent forming. The removal of fly ash from the filaments at the plasticizer spray chamber outlet remains a key concern in the industry. For example... Figure 1 As shown, conventional filter rod forming equipment is currently equipped with a fiber fly removal device at the outlet of the plasticizer spray chamber. The suction port of this device is a key component for handling fly accumulation. The suction port of the conventional fiber fly removal device is positioned above the fiber plane and perpendicular to the plasticizer spray chamber outlet. It is mainly used to remove the fiber fly generated after opening, effectively preventing its accumulation at the plasticizer spray chamber outlet and avoiding the resulting filter rod porosity problem.

[0003] However, this type of suction device has significant drawbacks. Firstly, its suction direction is perpendicular to the filament plane, resulting in a limited effective suction area. To completely remove fly ash, a large negative pressure suction is required, which undoubtedly increases energy consumption and operating costs. Simultaneously, the adjustable distance of the suction port is too small, making it difficult to flexibly adapt to different filament opening widths, thus limiting its application in actual production. Secondly, because the suction port of a conventional suction device is higher than the filament plane, it easily comes into contact with the filament edge when the filament width fluctuates. This contact not only interferes with the filament width but may also cause filament snagging, significantly increasing the risk of filter rod porosity and severely affecting filter rod quality.

[0004] To address the problems in existing technologies, a suction device with higher removal efficiency, greater adjustable distance to the left and right, and no interference with the width of the fiber bundle is needed. This device should promptly and completely remove fly ash from the fiber bundle at the outlet of the plasticizer spray chamber, allow for convenient adjustment of the suction position under different fiber bundle width conditions, and never contact the edges of the fiber bundle, thus solving the problem of fly ash accumulation and improving the production efficiency and quality of filter rods. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this utility model provides a fiber fly removal device. By installing the suction component on the opening machine table below the fiber bundle, the effective suction area is greatly increased. Furthermore, it is designed to move in a parallel direction, which greatly increases the adjustable distance to the left and right, allowing it to flexibly adapt to different fiber bundle opening widths and expanding its application range in actual production.

[0006] Specifically, this utility model provides a filament fly removal device, which includes a suction component and a filament fly collection chamber on an opening machine. The key feature is that during the operation of the opening machine, the suction port of the suction component is located below the filament bundle to suck up and clean the filament fly generated during the opening process. An opening is provided on the opening machine table, through which the sucked-up filament fly enters the filament fly collection chamber. The suction component is configured to move parallel to the opening machine table, adapting to different filament fly removal needs under various working conditions.

[0007] Furthermore, bolt holes are provided on the table surface of the opening machine for connecting the suction assembly.

[0008] Furthermore, the suction assembly includes: a mounting plate and fixed knurled bolts;

[0009] The mounting plate is equipped with an adjustment groove, and the fixed knurled bolts pass through the adjustment groove and connect to the bolt holes on the loosening machine table.

[0010] Loosen the fixed knurled bolts to release the fastening between the mounting plate and the opening machine table. Push the mounting plate to move within the length range of the adjustment groove in a direction parallel to the opening machine table to adjust the position of the mounting plate. After adjusting to the appropriate position, tighten the fixed knurled bolts to fix the mounting plate stably on the opening machine table to pick up the fly filaments.

[0011] Furthermore, a groove is provided below the mounting plate, through which the sucked filament fly waste is conveyed to the opening on the opening machine table.

[0012] Furthermore, a conveying port is provided above the mounting plate, and a first air intake is installed on the conveying port. The first air intake is used to suck up the filament fly generated during the operation of the opening machine, and the sucked filament fly enters the groove along the conveying port.

[0013] Furthermore, the connection hole, placement groove, second air intake, and telescopic tube are described; the connection hole is set on the mounting plate, and the sucked-up filaments enter the groove along the connection hole; the placement groove is set on the mounting plate, and the size of the placement groove is set to be adapted to the second air intake for storing the second air intake; the telescopic tube is set to be telescopic, with one end connected to the connection hole and the other end connected to the second air intake, and the filaments sucked up by the second air intake enter the connection hole along the telescopic tube.

[0014] Furthermore, when the telescopic tube opening machine is running, the telescopic tube retracts, and the second air inlet engages and is placed in the placement groove to suck up the filaments generated during the operation of the opening machine;

[0015] When the opening machine is stopped, the telescopic tube is extended and the second air inlet is moved to suck up the fly filaments on the opening machine table.

[0016] Furthermore, the fiber fly waste collection chamber is located below the opening machine table and is used to collect the absorbed fiber fly waste.

[0017] Working Principle: Before operating the filament fly removal device, the operator must first check whether all parts of the equipment are intact. Based on the measured filament opening width data, the operator loosens the fixed knurled bolts 32 on the mounting plate 31 of the suction assembly 3, releasing the fastening between the mounting plate 31 and the table. The operator then pushes the mounting plate 31 to move it within the length range of the adjustment groove 34 in a direction parallel to the table of the opening machine 1, adjusting the suction assembly 3 to a position suitable for the filament working conditions. After the suction assembly 3 is in position, the operator tightens the fixed knurled bolts 32 again to firmly fix the mounting plate 31 to the table of the opening machine 1, preventing displacement of the suction assembly 3 during equipment operation and ensuring the stability and reliability of the suction operation.

[0018] Working principle of the first suction port 35: When the opening machine 1 opens the filament bundle and generates filament fly waste, the negative pressure power source connected to the suction assembly 3 is turned on, forming a negative pressure in the suction channel. Under the action of negative pressure, the first suction port 35 on the conveying port 36 above the mounting plate 31 sucks in the filament fly waste generated around the opening machine 1. The filament fly waste enters the groove 37 below the mounting plate 31 along the conveying port 36. Under the continuous airflow, the filament fly waste is conveyed through the groove 37 to the opening 12 on the table of the opening machine 1, and then enters the filament fly waste collection chamber 4 located below the table.

[0019] Working principle of the second air intake 39: When the opening machine 1 is running, the telescopic tube 38 retracts, and the second air intake 39 is engaged and placed in the placement groove 311. Under the action of negative pressure, it sucks up the filaments generated by the operation of the opening machine 1. The sucked-in filaments enter the connecting hole 310 on the mounting plate 31 along the telescopic tube 38, and then flow into the groove 37.

[0020] When the opening machine 1 stops, the telescopic tube 38 extends, and the operator moves the second air inlet 39 to suck up the remaining filaments and fly ash on the table of the opening machine 1.

[0021] Whether the filaments collected during operation or shutdown are in use, they will eventually enter the filament collection chamber 4 through the groove 37 and the opening 12.

[0022] Beneficial effects:

[0023] 1. This invention changes the suction direction by installing the suction component on the opening machine table below the yarn bundle, thus significantly increasing the effective suction area. Compared to conventional devices where the suction direction is perpendicular to the yarn bundle plane, resulting in a limited suction area, this invention can more efficiently remove yarn fly shavings without requiring excessive negative pressure suction to completely remove them, reducing energy consumption and operating costs.

[0024] 2. This utility model features a suction component that can move in a parallel direction, significantly increasing the adjustable distance to the left and right, thus flexibly adapting to different filament opening widths. In actual production, the suction position can be easily adjusted for filaments under various working conditions, greatly expanding the application range of the device and avoiding the problem of being unable to adapt to different filament widths due to the small adjustable distance of the suction port.

[0025] 3. The suction component of this invention is located below the filament bundle, avoiding contact between the suction component and the edge of the filament bundle. When the width of the filament bundle fluctuates, it will not interfere with the width of the filament bundle, nor will it cause filament snagging, effectively reducing the risk of adhesive holes in the filter rod, thereby significantly improving the quality of the filter rod.

[0026] 4. With the design of the adjustment groove and fixed knurled bolts on the mounting plate, the operator can easily adjust the position of the suction component according to the opening width of the filament bundle. The operation is simple and convenient, which improves the operating efficiency and stability of the equipment.

[0027] 5. The first air intake of this utility model is close to the operating area of ​​the opening machine, which can promptly remove the fly filaments generated during the opening process.

[0028] 6. The second air intake of this utility model is connected by a telescopic tube, which adopts different working modes when the loosening machine is running and stopping, further improving the removal effect of filament fly waste, ensuring that filament fly waste can be completely cleaned under various conditions, and improving the overall performance of the device.

[0029] 7. The groove below the mounting plate of this utility model, together with the opening on the opening machine table and the fiber shavings collection chamber, forms a highly efficient fiber shavings conveying and collection system. The groove design facilitates the smooth flow of fiber shavings into the opening and then into the collection chamber. At the same time, the internal structure of the collection chamber effectively separates the fiber shavings from the airflow, achieving efficient collection of fiber shavings and ensuring the smooth progress of the cigarette filter rod forming process.

[0047] The technical solution will now be described in detail with reference to the accompanying drawings of the embodiments of this utility model.

[0048] Example 1

[0049] like Figure 4 , 10 As shown, a filament fly shaving removal device includes: a suction assembly 3, a mounting plate 31, a fixed knurled bolt 32, bolt holes 33, an adjusting groove 34, a first air intake 35, a conveying port 36, a groove 37, and a filament fly shaving collection chamber 4. The suction assembly 3 and the filament fly shaving collection chamber 4 are mounted on an opening machine 1. During the operation of the opening machine 1, the air intake of the suction assembly 3 is located below the filament 2 and is used to suck up the filament fly shavings 21 generated during the opening of the filament 2. An opening 12 is provided on the table 11 of the opening machine 1, and the sucked filament fly shavings 21 enter the filament fly shaving collection chamber 4 through the opening 12. The suction assembly 3 is configured to move in a direction parallel to the table 11 of the opening machine 1 to adapt to the filament fly shavings 21 suction requirements under different working conditions.

[0050] like Figure 8 As shown, bolt holes 33 are provided on the table 11 of the opening machine 1 for connecting the mounting plate 31. The mounting plate 31 is provided with an adjustment groove 34, and the fixed knurled bolts 32 pass through the adjustment groove 34 and connect to the bolt holes 33 on the table 11 of the opening machine 1. Loosening the fixed knurled bolts 32 releases the fastening state between the mounting plate and the table 11 of the opening machine 1, and pushes the mounting plate to move in a direction parallel to the table 11 of the opening machine 1 within the length range of the adjustment groove 34 to adjust the position of the mounting plate 31. After adjusting to the appropriate position, tighten the fixed knurled bolts 32 to stably fix the mounting plate 31 on the table 11 of the opening machine 1 to pick up the fly filaments 21.

[0051] like Figure 8 As shown, there are 4 bolt holes 33. Select the appropriate bolt hole 33 to connect the mounting plate 31 according to the required position.

[0052] like Figure 5 , 13 As shown, the groove 37 is located below the mounting plate 31, and the sucked filament fly 21 is conveyed through the groove 37 to the opening 12 on the table 11 of the opening machine 1.

[0053] like Figure 5 As shown, the conveying port 36 is located above the mounting plate 31, and the first suction port 35 is installed on the conveying port 36. The first suction port 35 is used to suck up the filament fly 21 generated during the operation of the opening machine 1. The sucked filament fly 21 enters the groove 37 along the conveying port 36.

[0054] The fiber fly waste collection chamber 4 is located below the table 11 of the opening machine 1 and is used to collect the fiber fly waste 21.

[0055] like Figure 6 As shown, before operating the fiber fly removal device, the operator must first check whether all parts of the equipment are intact. Based on the measured opening width data of the fiber 2, the operator loosens the fixed knurled bolts 32 on the mounting plate 31 of the suction assembly 3, releasing the fastening between the mounting plate 31 and the table 11. The operator then pushes the mounting plate 31 to move it within the length range of the adjustment groove 34 in a direction parallel to the table 11 of the opening machine 1, adjusting the suction assembly 3 to a position suitable for the working conditions of the fiber 2. After the position of the suction assembly 3 is adjusted, the operator tightens the fixed knurled bolts 32 again to firmly fix the mounting plate 31 on the table 11 of the opening machine 1, preventing the suction assembly 3 from shifting during equipment operation and ensuring the stability and reliability of the suction operation.

[0056] When the opening machine 1 opens the filament bundle 2 and generates filament fly 21, the negative pressure power source connected to the suction assembly 3 is turned on, forming a negative pressure in the suction channel. Under the action of negative pressure, the first suction port 35 on the conveying port 36 above the mounting plate 31 sucks in the filament fly 21 generated around the opening machine 1. The filament fly 21 enters the groove 37 below the mounting plate 31 along the conveying port 36. Under the continuous airflow, the filament fly 21 is conveyed through the groove 37 to the opening 12 on the table 11 of the opening machine 1, and then enters the filament fly collection chamber 4 located below the table 11.

[0057] Example 2

[0058] like Figure 10 As shown, the difference from Embodiment 1 is that the suction assembly 3 includes: a telescopic tube 38, a second suction port 39, a connecting hole 310, and a placement groove 311; the second suction port 39 sucks up the filament fly 21, the connecting hole 310 is provided on the mounting plate 31, and the sucked filament fly 21 enters the groove 37 along the connecting hole 310;

[0059] like Figure 11 As shown, the placement slot 311 is disposed on the mounting plate 31, and the size of the placement slot 311 is set to be adapted to the second air intake 39 for storing the second air intake 39.

[0060] like Figure 13 As shown, the telescopic tube 38 is telescopic, with one end connected to the connection hole 310 and the other end connected to the second air intake 39. The filament fly 21 sucked by the second air intake 39 enters the connection hole 310 along the telescopic tube 38.

[0061] like Figure 11As shown, when the telescopic tube 38 is running, the telescopic tube 38 retracts and the second air inlet 39 is engaged and placed in the placement slot 311 to suck up the filament fly 21 generated by the operation of the opening machine 1; when the opening machine 1 is stopped, the telescopic tube 38 is extended and the second air inlet 39 is moved to suck up the filament fly 21 on the table 11 of the opening machine 1.

[0062] like Figure 7 As shown, when the opening machine 1 is running, the telescopic tube 38 retracts, and the second air intake 39 is engaged and placed in the placement groove 311. Under the action of negative pressure, it sucks up the filament fly 21 generated by the operation of the opening machine 1. The sucked-in filament fly 21 enters the connection hole 310 on the mounting plate 31 along the telescopic tube 38, and then flows into the groove 37.

[0063] When the opening machine 1 stops, the telescopic tube 38 is extended, and the operator moves the second air inlet 39 to suck up the remaining filaments and fly ash 21 on the table 11 of the opening machine 1.

[0064] Whether the filament fly 21 is collected during operation or shutdown, it eventually enters the filament fly 21 collection chamber 4 through the groove 37 and the opening 12.
