[0001] This utility model relates to the field of coiling machine technology, and in particular to an integrated coiling machine secondary air separation device screening and recycle management system. Background Technology

[0002] The cigarette rolling machine is a core piece of equipment in the tobacco industry. It is mainly used to automatically roll tobacco shreds and cigarette paper into cigarettes and to bond the filter tip to the cigarette paper, forming a complete filter cigarette. The secondary air separation device is an important component of the cigarette rolling machine, mainly used for secondary screening of the tobacco shreds, separating the shreds from the stems to ensure that the finished cigarettes meet quality requirements.

[0003] The waste yarn system in a secondary air separation unit is mainly used to process waste yarn, ensuring its efficient recycling and reuse. However, existing waste yarn systems often face problems such as insufficient dust removal efficiency and high waste yarn breakage rate, leading to a decline in waste yarn quality and resource waste.

[0004] To address the aforementioned shortcomings, an integrated secondary air separation device screening and recycle management system for a winding and splicing machine is provided to effectively improve the quality of recycled yarn. Utility Model Content

[0005] The purpose of this invention is to provide an integrated secondary air separation device screening and rewinding management system for a coiling machine to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides an integrated screening and recycle management system for a secondary air separation device of a cigarette rolling machine. The system includes a screening and recycle management body connected to the secondary air separation device of the cigarette rolling machine. The screening and recycle management body includes a dust collection assembly and a screen fixedly connected to the side plate of the cigarette rolling machine. The screen has an inlet, a return air outlet, and an outlet. The inlet is connected to the output tobacco pipe of the secondary air separation device via a tobacco pipe assembly. The return air outlet is connected to the dust collection assembly via a negative pressure return air pipe assembly. The output end of the dust collection assembly is connected to the central dust collector of the cigarette rolling machine. An inclined discharge long curved pipe is provided on the outlet.

[0007] Preferably, the tobacco pipe assembly includes a first corrugated pipe connected to the feed inlet, and the other end of the first corrugated pipe is connected to the output tobacco pipe of the secondary air classifier through multiple first straight pipes.

[0008] Preferably, the negative pressure return air duct assembly includes a second corrugated pipe connected to the return air inlet, the other end of the second corrugated pipe being connected to the dust collection assembly via multiple second straight pipes, and a make-up air valve being provided at the connection between the second corrugated pipe and the second straight pipes, one end of the make-up air valve being in communication with the air.

[0009] Preferably, the dust collection assembly includes a cyclone dust collector and a dust collection bin. The cyclone dust collector is provided with an air inlet pipe and an air outlet pipe. The air inlet pipe is arranged in a tangential direction and one end of the air inlet pipe is connected to the second straight pipe.

[0010] Preferably, the exhaust pipe is located at the top of the cyclone dust collector, and the exhaust pipe is connected to the central dust collector in sequence through a flexible hose and a steel pipe. The bottom of the cyclone dust collector is snapped into the dust collection bin by a buckle.

[0011] Preferably, the steel pipe is equipped with a pressure gauge and a throttle valve.

[0012] Preferably, the discharge direction of the discharge long bend is directly opposite the lower storage area of ​​the coiling machine.

[0013] Therefore, the integrated secondary air separation device screening and recycle management system for the winding and splicing machine with the above-described structure has the following beneficial effects:

Combine the use of cyclone dust collector and stainless steel dust collection bucket to efficiently separate dust through the dual action of centrifugal force and gravity, reduce the impurity content in the returned shreds, and at the same time reduce the load on the central dust removal system and extend the equipment life.

[0016] (3) By using the inclined design of the discharge long bend pipe, the high-speed airflow is avoided from interfering with the distribution of tobacco shreds in the steep-angle lifting belt, thus reducing the empty head rate and rejection rate; the modular pipe design simplifies the disassembly and assembly process, reduces the secondary impact on the quality of recycled tobacco shreds during maintenance, and improves resource utilization and production economy.

[0026] Example

[0027] like Figure 1 As shown, this utility model discloses an integrated secondary air separation device screening and recycle management system for a cigarette making machine. The system includes a screening and recycle management body connected to the secondary air separation device of the cigarette making machine. The screening and recycle management body includes a screener and a dust collection component. In this embodiment, the screener 1 is flanged and connected to the side plate of the feeding and forming machine (VE). The screener 1 is used to separate smoke and tobacco shreds. Its installation position eliminates the need for frequent disassembly and reassembly, significantly simplifying daily maintenance. The dust collection component 2 is also placed below the secondary recycle tape of the VE (inside the housing storing the VE motor and fan). The output end of the dust collection component 2 is connected to the central dust collector of the cigarette making machine to reduce the load and amount of smoke in the central dust collection system, further reducing smoke overflow. By hiding the dust collection component 2 inside the cigarette making machine, the on-site space layout is optimized, making the production environment cleaner and more aesthetically pleasing.

[0028] like Figure 2 As shown, the screener 1 has a feed inlet 3, a return air inlet 4, and a discharge outlet 5. The feed inlet 3 is connected to the output tobacco pipe of the secondary air separation device (such as...) through the tobacco pipe assembly 6. Figure 1 The pipe shown in Figure A is connected to the dust collection assembly 2 via the return air vent 4 through the negative pressure return air duct assembly 7. The flow direction of the tobacco duct assembly 6 is opposite to that of the negative pressure return air duct assembly 7. In this embodiment, a flange is set on the discharge port 5 on the screener 1. The flange of the discharge port 5 is connected to the VE side plate. The flange on the discharge port 5 is connected to the discharge long bend pipe 8. The discharge long bend pipe 8 is inclined and located inside the return vibrating groove protective cover. Its length is relatively long, and the discharge direction is directly facing the lower storage area of ​​the cigarette machine. It is used to directly transport the dust-removed tobacco to the storage area for recycling, so as to avoid the output airflow affecting the distribution and structure of tobacco on the steep-angle lifting belt, and avoid problems such as the increase of the empty tobacco rate and the increase of the rejection rate of too light or too heavy tobacco.

[0029] like Figure 3 As shown, the tobacco pipe assembly 6 is used to transport the tobacco output from the secondary air classifier to the screener 1 for processing. It includes a first corrugated pipe 61 connected to the feed inlet 3, and the other end of the first corrugated pipe is connected to the output tobacco pipe of the secondary air classifier through multiple first straight pipes 62.

[0030] The negative pressure return air duct assembly 7 is used to transport dust-laden gas to the dust collection assembly 2. It includes a second corrugated pipe 71 connected to the return air inlet 4. The other end of the second corrugated pipe 71 is connected to the dust collection assembly 2 via multiple second straight pipes 72. A makeup air valve 73 is installed at the connection between the second corrugated pipe 71 and the second straight pipes 72. One end of the makeup air valve 73 is connected to the second corrugated pipe 71 and the second straight pipe 72, and the other end is connected to the air. By reasonably adjusting the opening and closing degree of the makeup air valve 73, the air volume in the negative pressure return air duct assembly 7 is compensated, thereby regulating the flow rate of the output tobacco and the dust removal intensity. Specifically:

[0031] When the make-up air valve 73 is reduced, the negative pressure in the second bellows 71 increases, which increases the suction force on the tobacco in the screener 1, resulting in a decrease in the output speed of the tobacco. This effectively reduces the mechanical damage to the tobacco caused by the impact of high-speed airflow during the conveying process, thereby maintaining the structural integrity and quality stability of the tobacco. At the same time, the dust removal intensity increases, and the amount of dust in the dust collection bin 22 increases. Similarly, when the make-up air valve 73 is increased, the output speed of the tobacco increases, and the dust removal intensity decreases.

[0032] If the negative pressure return air duct assembly 7 becomes blocked, the make-up air valve 73 can be opened to its maximum and an air gun can be used to clean it, which can effectively unclog the return air duct and improve cleaning efficiency.

[0033] Connectors are used at the corners of the pipes in the tobacco pipe assembly 6 and the negative pressure return air pipe assembly 7, and they are connected in a conventional manner. Flexible first and second corrugated pipes 71 are used between the tobacco pipe assembly 6, the negative pressure return air pipe assembly 7 and the screener 1, which not only ensures the stability of the connection, but also improves the convenience of disassembly and assembly, and reduces the problem of loosening of the interface due to frequent disassembly and assembly.

[0034] Except for the first and second corrugated pipes 71, all other pipes and connectors are made of stainless steel or PVC, which reduces friction and breakage of tobacco during transportation and avoids problems such as loosening of interfaces or air leakage caused by airflow fluctuations or mechanical vibrations. It is suitable for high-speed tobacco transportation and long-term use under complex working conditions.

[0035] like Figure 4 As shown, the dust collection assembly 2 includes a cyclone dust collector 21 and a dust collection bin 22. The cyclone dust collector 21 is provided with an air inlet pipe 23 and an air outlet pipe 24. The air inlet pipe 23 is arranged tangentially and one end of the air inlet pipe 23 is connected to the second straight pipe 72. The air outlet pipe 24 is located at the top of the cyclone dust collector 21. The air outlet pipe 24 is connected to the central dust collector in sequence through a flexible hose 25 and a steel pipe 26 (the central dust collector generates negative pressure airflow, which in turn attracts the airflow in the dust collection assembly 2 and the negative pressure return air duct assembly 7). The flexible hose 25 can simplify the installation process and improve maintenance efficiency. The steel pipe 26 is equipped with a pressure gauge 28 and a throttle valve 29. The throttle valve 29 is used to adjust the flow rate of the gas drawn into the cyclone dust collector 21 (from the cyclone dust collector 21).

[0036] The dust collection assembly 2 has a negative pressure inside, which transports the dust-laden gas tangentially into the cyclone dust collector 21. The gas rotates inside the cyclone dust collector 21, and the dust particles are thrown towards the inner wall under the action of centrifugal force. The rotating airflow gradually moves downward inside the dust collector, and after reaching the bottom, it reverses and rises, forming an internal vortex. The purified gas is discharged through the exhaust pipe 24 at the top of the cyclone dust collector 21. The bottom of the cyclone dust collector 21 is connected to the dust collection bucket 22 by a buckle 27. The dust collection bucket 22 is made of stainless steel and is used to collect the dust separated by the cyclone dust collector 21 and falling due to gravity.

[0037] The screening and rewinding methods of the integrated winding and splicing machine's secondary air separation device screening and rewinding management system are as follows:

[0038] The secondary air separation device transports the dust-laden tobacco shreds to the screener 1 via the tobacco shred pipe assembly 6. Simultaneously, the negative pressure dust removal assembly screens the dust-laden tobacco shreds in the screener 1 via the negative pressure return air shred assembly 7. After dust removal and speed reduction, the tobacco shreds are transported to the storage area for recycling via the discharge long curved pipe 8. The dust-laden gas is drawn into the cyclone dust collector 21. After being processed by the cyclone dust collector 21, the purified gas enters the central dust collector for further centralized dust collection. The separated dust particles fall into the dust collection bin 22 under gravity. The load on the central dust collector can be reduced and its service life extended simply by opening the buckle 27 and cleaning the dust collection bin 22 periodically.

[0039] Therefore, this utility model adopts an integrated secondary air separation device screening and tobacco recycling management system for a cigarette making machine with the above-mentioned structure. By adjusting the air supply valve to control the negative pressure airflow intensity, the tobacco flow rate can be flexibly adjusted, reducing the mechanical friction and airflow impact of the tobacco during the conveying process, significantly reducing the tobacco breakage rate, and ensuring the integrity of the recycled structure and the stability of quality.

[0040] The sieve is fixed to the side plate of the coiling machine, eliminating the need for frequent disassembly and ensuring the continuity and accuracy of the sieving process, effectively separating qualified tobacco shreds from impurities; combined with the use of a cyclone dust collector and a stainless steel dust collection bin, the dust is efficiently separated through the dual action of centrifugal force and gravity, reducing the impurity content in the recycled tobacco shreds, while also reducing the load on the central dust collection system and extending the equipment life;

[0041] The inclined design of the discharge long bend pipe avoids interference from high-speed airflow on the distribution of tobacco shreds in the steep-angle lifting belt, reducing the empty head rate and rejection rate; the modular pipe design simplifies the disassembly and assembly process, reduces the secondary impact on the quality of recycled tobacco shreds during maintenance, and improves resource utilization and production economy.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
