Description

Technical Field

[0001] The invention belongs to the technical field of cigarette manufacturing, and in particular relates to a device for reducing dust accumulation in a cigarette feeding machine. Background Art

[0002] The function of a tobacco feeder in cigarette making equipment is to process air-fed tobacco into tobacco bundles. The quality of its internal structure is the foundation of cigarette quality. The currently widely used domestic ultra-high-speed dual-track cigarette making machine is a very representative model. The inner and outer track suction and forming processes differ, as do the component structure, shape and size, effective length, and the suction belt path used in the final process.

[0003] like Figure 1-2 As shown, the chopper mechanism's chopper and brush wheel remove excess tobacco from the suction guide according to the target weight, forming a tobacco bundle of the required structural quality. The removed tobacco is then returned to the storage area at the rear of the tobacco feeder for reuse. Due to the high concentration of dust and fines in the tobacco waste, during high-speed production, tobacco falling from the high-level hopper, much of the flying dust, falls and accumulates on the protective cover of the spiral auger, where the space protrudes outward and the inclined plate below it, forming a thick layer of dust. Under the influence of gravity, this accumulated tobacco dust clumps along the inclined plate of the original equipment and enters the tobacco bundle along the steep-angled lifting belt. The accumulated tobacco dust degrades the purity of the tobacco, exceeding the equipment's inherent purification capacity and damaging the inherent quality of the finished cigarette.

[0004] The existing equipment cannot avoid the problem of dust accumulation in the tobacco feeder, which in turn affects the quality of cigarette tobacco. Summary of the Invention

[0005] In view of this, the present invention provides a device for reducing dust accumulation in a tobacco feeder, which can solve the problem of dust accumulation in the tobacco feeder affecting tobacco quality.

[0006] The present invention is achieved in that:

[0007] The present invention provides a device for reducing dust accumulation in a wire feeding machine, comprising a dust collecting device, a partition baffle device, a positive pressure blowpipe, a push-on / off valve and a funnel, wherein the partition baffle device is installed directly below the water level spiral auger of the wire feeding machine, the funnel is connected to the bottom of the partition baffle device, the dust collecting device connects the funnel and the centralized dust removal pipe of the wire feeding machine, the positive pressure blowpipe is installed on the side wall panel of the wire feeding machine away from the return wire inlet, the air outlet of the positive pressure blowpipe is aligned with the surrounding of the rotating dragon cover of the wire feeding machine and the protective door of the wire feeding machine, and is used to blow the falling dust into the funnel, the push-on / off valve is installed at the front end of the branch pipe of the centralized dust removal pipe, and the push-on / off valve is used to adjust the suction wind force of the centralized dust removal pipe.

[0008] On the basis of the above technical solution, the device for reducing dust accumulation in the wire feeding machine of the present invention can also be improved as follows:

[0009] Wherein, the partition baffle device includes an inclined plate and a partition baffle, the inclined plate replaces the original inclined plate part below the spiral auger and is fixedly connected to the partition baffle, the partition baffle is fixed above the inclined plate, the fixing angle between the inclined plate and the partition baffle is greater than 90 degrees, the length of the inclined plate and the partition baffle is equal to the length of the wire feeding machine side wall plate inside the wire feeding machine side wall plate, the inclined plate and the partition baffle are installed between the two wire feeding machine side wall plates by fixing bolts, The partition baffle is used to separate the accumulated dust from the tobacco; the funnel is arranged below the inclined plate, the top surface of the funnel is larger and the bottom surface is smaller, the longest width of the funnel is larger than the inclined plate, one side of the top surface of the funnel is tightly fixed to the folded edge of the bottom surface of the inclined plate, and the funnel is used to collect the fallen dust; the dust collecting device includes a multi-way cluster valve and a funnel hose, the inlet of the multi-way cluster valve is connected to the bottom of the funnel through the funnel hose, and the outlet of the multi-way cluster valve is connected to the centralized dust removal pipe.

[0010] The extension range of the partition baffle exceeds the width of the upper spiral auger.

[0011] By setting a partition baffle on the inclined plate, the accumulated dust can be separated from the tobacco, and then the falling dust is collected by the funnel under the inclined plate; by setting a multi-way cluster valve, the inlet of the multi-way cluster valve is connected to the funnel through the funnel hose, and the outlet is connected to the branch pipe of the centralized dust removal pipe, so that the dust collected by the funnel is finally sucked away by the centralized dust removal pipe; by setting a flat push opening and closing valve installed in front of the branch pipe of the centralized dust removal pipe, the suction wind force of the centralized dust removal pipe can be adjusted, which is convenient for use according to needs; by setting a positive pressure blowpipe, excessive dust can be prevented from adhering to the surface of surrounding parts or protective doors. By collecting and sucking away the falling dust, dust can be prevented from mixing into the tobacco, which is beneficial to improving the quality of cigarette tobacco.

[0012] Furthermore, the upper edge of the partition baffle is a beveled edge parallel to the bottom of the spiral auger, and the partition baffle includes a main board, a mesh plate, a hinge and a support assembly. The main board is fixed to the inclined plate through the hinge, and the mesh plate is fixed to the main board. The mesh plate has mesh holes and long holes. The mesh holes are used to allow dust falling on the partition baffle to leak onto the inclined plate, and the long holes are used to adjust the size of the gap between the mesh plate and the bottom of the rotating dragon cover above. The partition baffle can be lifted or lowered around the hinge, and the support assembly is used to position the inclination angle of the partition baffle.

[0013] The support assembly includes a lower support block, the upper support block is fixed on the main board, the upper support block is fixed on the inclined plate, the U-shaped support rod is inserted into the holes of the lower support block and the upper support block, the fixing clip is installed on the support rod, and can move up and down and rotate on the support rod, the long hole of the lower support block is used to move back and forth to adjust the inclination angle of the main board, the shape, size and position of the upper support block are consistent with the slot hole of the long slot, and the fixing clip is installed in the middle of the support rod.

[0014] By setting the mesh holes, dust that falls on the partition baffle can leak onto the inclined plate; by setting the partition baffle, it can be lifted or lowered around the hinge axis, which is convenient for meeting small-scale operation and maintenance needs; by setting the fixing buckle, the support rod can be prevented from falling off from the working position; by setting the fixing buckle and installing it in the middle part of the support rod to form a combination, it can prevent the fixing buckle from being lost due to being too small.

[0015] Furthermore, the inclined plate has a long slot, a funnel fixing screw hole, a partition baffle fixing screw hole, a partition baffle hinge fixing screw hole, a storage area cover fixing screw hole, and a wall panel fastening screw hole. The long slot has a transparent slot hole, the width of the long slot is consistent with the width of the funnel, and the installation position of the long slot corresponds to the funnel. The funnel fixing screw hole is used to bolt the funnel, the partition baffle fixing screw hole is used to bolt the support assembly of the partition baffle, the partition baffle hinge fixing screw hole is used to bolt the hinge of the partition baffle, and the partition baffle hinge fixing screw hole is used to bolt the inclined plate to the storage area cover of the wire feeding machine by bolt connection. The wall panel fastening screw hole is used to bolt the inclined plate to the side wall panel of the wire feeding machine.

[0016] The beneficial effect of adopting the above-mentioned improvement scheme is: by providing a transparent long groove, the width of the long groove is consistent with the width of the funnel, which is conducive to the collection of accumulated dust and sliding into the funnel.

[0017] Furthermore, the funnel has two sub-funnels, and the funnel has a collection outlet, a collection inlet, a flange and a mounting hole. The collection inlet is located at the upper top of the funnel, and the shape and size of the collection inlet are larger than the long groove on the inclined plate. The flange is used to connect the collection inlet and the inclined plate. The opening position of the mounting hole corresponds to the position of the funnel fixing screw hole during installation, and is used to fix the funnel on the inclined plate with screws. The collection outlet is at the bottom of the funnel.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting up two groups of sub-funnel, two dust collection inclined plates are added, which is conducive to the dust gathering at the bottom of the funnel. The space between the sub-funnel is conducive to extending the arm from the middle to remove the screws during maintenance.

[0019] Among them, a rubber pad is pasted on the surface of the flange during installation.

[0020] By adding a rubber gasket between the flange and the inclined plate during installation, the sealing between the flange and the bottom surface of the inclined plate is enhanced.

[0021] Each of the sub-funnel has three collecting outlets, and the outlet ends of the collecting outlets are circular tubes.

[0022] By setting each sub-funnel with three collection outlets, compared with the design of each sub-funnel with a single collection outlet, it is beneficial to the uniformity of suction distribution, and can also prevent dust from adhering to and depositing on the inner wall of the sub-funnel and failing to slide to the bottom in time, causing blockage; by setting the outlet end of the collection outlet as a round tube, it is convenient to connect the hose.

[0023] Furthermore, the multi-way cluster valve includes a cylinder, an inlet, an outlet, a bottom plate, an end cover and a fixed plate. The inlet and the outlet are connected to the cylindrical cylinder. Multiple inlets are connected to the collection outlet through the funnel hose. A single outlet is connected to the branch pipe of the centralized dust removal pipe through the funnel hose via the push-open / close valve. The end cover is fixed to the flange above the cylinder with bolts, and the bottom plate is fixed to the fixed plate and the crossbeam of the bottom frame of the wire feeding machine with bolts.

[0024] Furthermore, the cylinder is provided with a gate plate, which divides the inner cavity of the cylinder into two parts and is used to adjust the relative size of the suction air volume leading to the funnel. The gate plate is fixed in the cylinder through a gate plate shaft.

[0025] Among them, a knurled nut is installed at one end of the gate shaft, the upper end of the knurled nut passes through the end cover, and a direction handle is installed on the part of the knurled nut on the end cover, and the direction handle is long and strip-shaped.

[0026] The cigarette making machine hopper has a one-way feeding mode. Since the dust runs at a relatively high speed in the wire feeding pipe, there is a phenomenon that there is more dust on one side of the hopper, resulting in more dust accumulation on the inclined plate behind the wire feeding machine. By adjusting the gate plate, the sub-funnel on the side with more dust can be made to suck more air, which is conducive to balancing the wind force and improving the dust removal effect.

[0027] Furthermore, the flat push opening and closing valve has an inner cone valve body, a flat push tube and a sealing ring, the flat push tube is inserted into the inner cone valve body, and the sealing ring is arranged at the connection between the flat push tube and the inner cone valve body; the inner cone valve body has a positioning groove, a closing cone, a support wing, and a sealing groove, the flat push tube has a positioning boss and a closing cone mouth, the positioning groove is arranged on the tube body of the inner cone valve body, the support wing is arranged on the upper part of the inner cavity of the inner cone valve body, and the sealing groove is used to fix the sealing ring; the positioning boss is arranged on the outer tube wall where the flat push tube contacts the inner cone valve body, and the positioning boss is consistent in size and shape with the positioning groove.

[0028] Among them, the positioning groove has two upper and lower rows of serrations, and the serrations are staggered. The overall closed cone is spindle-shaped, and multiple support wings fix the closed cone on the inner cone valve body. The edges of the support wings are streamlined and rounded.

[0029] By arranging the positioning grooves in a zigzag shape, the number and fineness of positioning on the inner cone valve body in the push-pull tube are increased; by setting the overall closing cone to be spindle-shaped, the supporting wings fix the closing cone to the outer tube, and the edges of the supporting wings are streamlined and rounded, so that the closing cone makes the channel of the push-pull opening and closing valve more streamlined, which is conducive to the passage of gas; compared with traditional valves, in the process of adjusting the opening of the push-pull opening and closing valve without adjusting the suction size, it can better ensure the smoothness of dust passage, and prevent the phenomenon of debris getting stuck on the inner edge of the valve and gathering more and more to cause blockage.

[0030] Furthermore, the positive-pressure blowpipe is used to apply positive-pressure blowing to the surrounding area of ​​the rotating dragon cover and the protective door. The positive-pressure blowpipe comprises a blowpipe, a lower blow port, a rear blow port, a blowing hose, a throttle valve, a control valve, and a connecting hose. The blowpipe is a metal circular tube sealed at one end and open at the other end. The lower blow port and the rear blow port are staggered on the tube wall. The lower blow port is used to blow air toward the long slot, and the rear blow port is used to blow air toward the protective door; the blowing hose is connected to the blowpipe, and the blowing hose passes through the original circular hole of the wire feeding machine side wall panel to the outside of the wire feeding machine; the throttle valve is used to adjust the blowing size of the positive-pressure blower, the control valve connects the connecting hose and the throttle valve, and the connecting hose is connected to the air source pipe of the positive-pressure blower; the positive-pressure blowpipe is fixed to the wire feeding machine side wall panel through the left bracket and the right bracket.

[0031] Wherein, the control valve is a pneumatic pilot valve or a solenoid valve, which is controlled to be turned on by the equipment startup signal.

[0032] Among them, the positive pressure blowpipe is fixed on the side wall panel of the wire feeding machine using the left bracket and the right bracket through the original screw holes of the original equipment.

[0033] By making the rear air outlet blow downward to the protective door, dust accumulation on the protective door is prevented, ensuring that the window on the protective door is clean; the lower air outlet blows toward the long slot to prevent dust accumulation on the surrounding parts; by setting the control valve to be controlled by the equipment start-up signal and stopping the control valve to blow air when the equipment is shut down, the energy loss of compressed air can be reduced.

[0034] Furthermore, it also has a new type of auger guard plate, which is installed on the rotating dragon cover of the wire feeding machine. The new auger guard plate includes a guard plate and an adjustment plate. The side of the guard plate is provided with an inner groove and an outer groove. The inner wall of the guard plate is fixed with a long guard plate hole. The guard plate is fixed to the rotating dragon cover through the long guard plate hole and the dragon cover bolt on the rotating dragon cover. The adjustment plate is installed on the dragon cover bolt corresponding to the inner groove through the long adjustment plate hole. The long guard plate hole is used to fix the guard plate to the rotating dragon cover through the dragon cover bolt.

[0035] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting a guard plate, the length extending out of the edge of the rotating dragon cover can be adjusted within the range of the long hole of the adjustment plate, and the difference in the length of the outer groove and the inner groove extending out of the edge of the rotating dragon cover can also be adjusted to a certain extent.

[0036] The rational shape and size of the long holes in the guard plate allow for a wider adjustment range for the overall distribution of the waste yarn between the inner and outer channels, ensuring a balanced and consistent distribution of waste yarn between the inner and outer channels. The grooves ensure that as much waste yarn as possible falls into the specific section corresponding to the suction guide rail in the suction chamber. The tobacco in this section is attracted to the upper middle layer during the tobacco bundle stacking process, resulting in the upper and lower layers of the tobacco bundle containing more filaments. This ensures that as much waste yarn as possible is wrapped in filaments, preventing repeated scraping and fragmentation, and helping to maintain the structural shape of the tobacco bundle during repeated contraction and expansion.

[0037] Compared with the prior art, the beneficial effects of the device for reducing dust accumulation in the tobacco feeding machine provided by the present invention are as follows: by arranging a separation baffle on the inclined plate, the accumulated dust can be separated from the tobacco, and then the falling dust can be collected by the funnel under the inclined plate; by arranging a multi-way cluster valve, the inlet of the multi-way cluster valve is connected to the funnel through the funnel hose, and the outlet is connected to the branch pipe of the centralized dust removal pipeline, so that the dust collected by the funnel is finally sucked away by the centralized dust removal pipeline; by arranging a horizontal push opening and closing valve installed in front of the branch pipe of the centralized dust removal pipeline, the suction wind force of the centralized dust removal pipeline can be adjusted. It is small and easy to use according to needs; by setting a positive pressure blowpipe, it prevents excessive dust from adhering to the surface of surrounding parts or protective doors, and by collecting and sucking away the falling dust, it prevents dust from mixing into tobacco, which is beneficial to improving the quality of cigarette tobacco; the cigarette making machine hopper is a one-way feeder. Since the dust runs at a relatively fast speed in the wire feeding pipe, there is a phenomenon that one side of the hopper contains more dust, resulting in a phenomenon that more dust accumulates on the inclined plate behind the wire feeding machine. By adjusting the gate, the sub-funnel on the side with more dust can suck more air, which is beneficial to balancing the wind force and improving the dust removal effect.

[0067] like Figure 7 As shown, further, in the above technical solution, the funnel 3 has two sub-funnels, and the funnel 3 has a collecting outlet 31, a collecting inlet 32, a flange 33 and a mounting hole 34. The collecting inlet 32 ​​is located at the upper top of the funnel 3. The shape and size of the collecting inlet 32 ​​are larger than the long groove 11 on the inclined plate 1. The flange 33 is used to connect the collecting inlet 32 ​​and the inclined plate 1. The opening position of the mounting hole 34 corresponds to the position of the funnel fixing screw hole 12 during installation, and is used to fix the funnel 3 on the inclined plate 1 with screws. The collecting outlet 31 is at the bottom of the funnel 3.

[0068] When in use, align the mounting holes 34 on the flange 33 with the funnel fixing screw holes 12 of the inclined plate 1, place a rubber pad between the funnel 3 and the inclined plate 1, and use bolts to pass through the funnel fixing screw holes 12 and the corresponding mounting holes 34 to fix the funnel 3 and the inclined plate 1 together;

[0069] When dust enters the two sub-funnel collection inlets 32 from the long slot 11 , the dust slides downward along the inclined plates of the sub-funnel to the collection outlet 31 , and is sucked away by the multi-way cluster valve 4 from the collection outlet 31 .

[0070] like Figure 8-9As shown, further, in the above technical solution, the multi-way cluster valve 4 includes a cylinder 41, an inlet 42, an outlet 43, a bottom plate 44, an end cover 45 and a fixed plate 46. The inlet 42 and the outlet 43 are connected to the cylindrical cylinder 41, and multiple inlets 42 are connected to the collection outlet 31 through a funnel hose 401. A single outlet 43 is connected to the branch pipe of the centralized dust removal pipe 74 through the funnel hose 401 via a push-open / close valve 5. The end cover 45 is fixed to the flange mouth above the cylinder 41 with bolts, and the bottom plate 44 is fixed to the fixed plate 46 and the bottom frame beam of the wire feeding machine with bolts.

[0071] Furthermore, in the above technical solution, a gate plate 48 is provided in the cylinder 41 , which divides the inner cavity of the cylinder 41 into two parts and is used to adjust the relative size of the suction air volume leading to the funnel 3 . The gate plate 48 is fixed in the cylinder 41 through the gate plate shaft 481 .

[0072] During use, the gate plate 48 is twisted to increase the suction force of the three inlets 42 on one side and reduce the suction force of the three inlets 42 on the other side. When twisted to a certain angle, the suction force of the inlets 42 on one side can be closed. A 90° twist can completely shut off the suction of the inlets 42 on both sides, even if the multi-way cluster valve 4 enters the closed state. Manually loosen the knurled nut 482 to rotate and change the direction of the gate plate 48. After tightening, the gate plate 48 is circumferentially positioned. The direction handle 49 serves as a rotation handle for the gate plate 48 and also as a circumferential positioning pointer for the gate plate 48.

[0073] like Figure 10-11 As shown, further, in the above technical scheme, the flat push opening and closing valve 5 has an inner cone valve body 51, a flat push tube 52 and a sealing ring 53, the flat push tube 52 is inserted into the inner cone valve body 51, and the sealing ring 53 is arranged at the connection between the flat push tube 52 and the inner cone valve body 51; the inner cone valve body 51 has a positioning groove 511, a closing cone 512, a support wing 513, and a sealing groove 514, the flat push tube 52 has a positioning boss 521 and a closing cone mouth 522, the positioning groove 511 is arranged on the tube body of the inner cone valve body 51, the support wing 513 is arranged on the upper part of the inner cavity of the inner cone valve body 51, and the sealing groove 514 is used to fix and install the sealing ring 53; the positioning boss 521 is arranged on the outer tube wall where the flat push tube 52 contacts the inner cone valve body 51, and the positioning boss 521 is consistent in size and shape with the positioning groove 511.

[0074] During manufacturing, the horizontal push on-off valve 5 is made by 3D printing.

[0075] When in use, insert the push tube 52 into the inner cone valve body 51, and at the same time put the sealing ring 53 into the sealing groove 514, align the positioning boss 521 of the push tube 52 with the positioning groove 511, so that the push tube 52 is stuck in the appropriate positioning groove 511, thereby fixing the push tube 52 on the inner cone valve body 51.

[0076] like Figure 12 As shown, further, in the above technical solution, the positive pressure blowpipe 6 is used to apply positive pressure blowing to the surrounding of the rotating dragon cover 71 and the protective door. The positive pressure blowpipe 6 has a blowpipe 61, a lower blowing port 62, a rear blowing port 63, a blowing hose 64, a throttle valve 65, a control valve 66, and a connecting hose 67. The blowpipe 61 is a metal circular tube with one end sealed and the other end open. The lower blowing port 62 and the rear blowing port 63 are staggered on the tube wall. The lower blowing port 62 is used to blow air to the long slot. 11 Blowing, the rear blowing port 63 is used to blow air toward the protective door; the blowing hose 64 is connected to the blow pipe 61, and the blowing hose 64 passes through the original round hole of the wire feeding machine side wall panel 73 to the outside of the wire feeding machine; the throttle valve 65 is used to adjust the blowing size of the positive pressure fan, and the control valve 66 connects the connecting hose 67 and the throttle valve 65, and the connecting hose 67 is connected to the air source pipeline of the positive pressure fan; the positive pressure blow pipe 6 is fixed on the wire feeding machine side wall panel 73 through the left bracket 68 and the right bracket 69.

[0077] During use, the original bolts on the wire feeding machine side wall panel 73 are used to pass through the left bracket 68 and the right bracket 69 to fix the blow pipe 61 between the two opposite wire feeding machine side wall panels 73. After the control valve 66 is opened, the throttle valve 65 is used to adjust the wind speed. The wind passes through the lower blowing port 62 to blow positive pressure toward the long slot 11 of the inclined plate 1, and the wind passes through the rear blowing port 63 to blow positive pressure backward and downward on the protective door, so that the fallen dust is brought into the long slot 11 and enters the collection inlet 32 ​​of the funnel 3, preventing dust from accumulating on the protective door.

[0078] like Figure 13 As shown, further, in the above technical solution, there is also a new type of auger guard plate 8, which is installed on the rotating dragon cover 71 of the wire feeding machine. The new auger guard plate 8 includes a guard plate 81 and an adjustment plate 82. The side of the guard plate 81 is provided with an inner groove 811 and an outer groove 812. The inner wall of the guard plate 81 is fixed with a guard plate long hole 813. The guard plate 81 is fixed to the rotating dragon cover 71 through the guard plate long hole 813 and the dragon cover bolt 713 on the rotating dragon cover 71. The adjustment plate 82 is installed on the dragon cover bolt 713 corresponding to the inner groove 811 through the adjustment plate long hole 821.

[0079] When in use, the adjustment plate 82 is installed on the dragon cover bolt 713 corresponding to the inner groove 811 through the adjustment plate long hole 821.

[0080] like Figure 14As shown, after being pushed parallel to the fluidized bed, the tobacco accumulates and thickens linearly on the high-speed suction ribbon 87. Taking the outer fluidized bed tobacco layer 83 as an example, it is divided into four sections according to the conventional ratio of waste tobacco. The waste tobacco in the waste section 834 corresponds to the bottom layer of the outer tobacco bundle 85. Most of it will be cut and brushed by the splitter mechanism and transported to the spiral auger 712 at the rear of the tobacco feeder for reuse. It is important to minimize waste tobacco from re-entering this section to prevent repeated breakage. The upper section 831 and lower section 833 correspond to the upper and lower layers of the formed tobacco bundle. The outer groove 812 corresponds to the middle section, ensuring that as much waste tobacco as possible is absorbed by the suction ribbon 87 and placed in the middle layer of the formed tobacco bundle, surrounded by the better-quality tobacco from the upper and lower layers. This not only prevents repeated cutting and brushing, but also, to a certain extent, eliminates quality problems such as broken tobacco at the end of the cigarette, empty ends, bamboo knots, too light, and too heavy cigarettes.

[0081] Through research and improvement on the quality improvement of the inner and outer channel tobacco bundle forming structure on the cigarette making machine, the following achievements have been made: 1. The distribution of inner and outer channel tobacco is more balanced in structure; 2. The purity of tobacco is improved; 3. The stacking distribution of tobacco waste in the cross section of the tobacco bundle is improved, the repeated crushing is greatly reduced, the deterioration of tobacco caused by processing is alleviated, and the waste of tobacco end drop and crushing is reduced; 4. Samples are taken from the inner and outer channels respectively, and it can be seen from the actual measurement graph of cigarette density given by the test bench that the average value of the maximum density of the outer channel tight head is 297.81mg / cm3, while that of the inner channel is 294.28mg / cm3, which are basically close. In particular, the density of the outer channel tobacco rod tight head has been significantly improved, from 280.22mg / cm3 before the improvement to 297.81, which is consistent with the density of the inner channel tight head, and the difference in homogeneity of double-channel forming is significantly reduced. 5. From the shift log report displayed on the equipment centralized control, it can be seen that the previous situation where the inner and outer tracks had a several-fold difference in short-end rejection rates has changed from frequent to extremely rare, and the phenomenon of a large difference between the two tracks has become rare. The number of short-end defects rejected in cigarettes and packaging as a whole has decreased, which is conducive to reducing consumption, increasing efficiency and improving internal quality.

[0082] Among them, throttle valve 65 adopts 304 stainless steel pneumatic air pipe joint speed regulating one-way flow limiting cylinder throttle valve SL6-01 produced by Ningbo Musanjie Automation Technology Co., Ltd. The throttle valve is made of 304 thickened material, which is corrosion-resistant and rust-proof, and can withstand 3.0MPA high pressure and can be used in an environment of -30℃-200℃.

[0083] The control valve 66 adopts the FESTO pneumatic solenoid valve MHE3-MS1H-3 of Xiamen Depin Electric Co., Ltd. This solenoid valve has efficient and fast response, long service life and can be durable.

[0084] Specifically, the principle of the present invention is: the waste wire cut by the chopping knife mechanism 004 is pushed to the waste wire inlet 711, and the spiral auger 712 transports the waste wire into the wire feeding machine and falls downward into the storage area cover 75. The partition baffle 2 extends the storage area cover 75 to the bottom of the rotating dragon cover 71 to prevent external accumulated dust from entering the storage area; when dust enters the collection inlet 32 ​​of the two sub-funnel from the long groove 11, the dust slides downward along the inclined plate of the sub-funnel to the collection outlet 31, and is sucked away from the collection outlet 31 by the multi-way cluster valve 4; after the control valve 66 is opened, the wind speed is adjusted by the throttle valve 65, and the wind blows positive pressure to the long groove 11 of the inclined plate 1 through the lower blowing port 62, and the wind blows backward and downward through the rear blowing port 63 to the protective door with positive pressure, so that the fallen dust is brought into the long groove 11 and enters the collection inlet 32 ​​of the funnel 3, preventing dust from accumulating on the protective door.

[0085] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
