Description

Generally, permanent magnets are installed on the tobacco processing line to remove strongly magnetic metals. However, this method is not ideal for removing non-magnetic debris such as stainless steel, copper, and aluminum, and it cannot remove dust and fine debris from the tobacco shreds, resulting in low-quality finished products.

The tobacco shreds after being air-classified by the air classifier de-debris device 400 fall into the steep slope feeding conveyor belt 500, and the end of the steep slope feeding conveyor belt 500 extends toward the purified tobacco shreds outlet 600.

[0058] The protective cover 100 primarily protects against impurities from entering while ensuring constant internal temperature and humidity. The tobacco shred vibration screening conveyor belt 200 is a primary vibration screening structure. The vibration frequency of the tobacco shred vibration screening conveyor belt 200 can be adjusted according to the tobacco shred screening requirements. The tobacco shred vibration screening conveyor belt 200 has a debris screening hole array 231. During vibration, tobacco shreds sink and are removed from the holes of the debris screening hole array 231, and the debris falls into the tobacco shred collection device 300. The air separation debris removal device 400 is a secondary tobacco shred purification device. It can separate fine debris from tobacco shreds through the action of air. Fine debris is blown to a distance. The air separation debris removal device 400 has the function of adjusting the direction and magnitude of the airflow to meet the removal requirements of different tobacco shreds. The steep slope conveyor feeding conveyor belt 500 conveys the high-quality tobacco shreds after secondary purification to the elevated purified tobacco shred discharge port 600 for product production. The purified tobacco shred discharge port 600 is an elevated tobacco shred conveying outlet that directly connects to the next production process.

[0059] In some embodiments, the tobacco vibration screening conveyor belt 200 includes a vibration conveying device 210, a bottom strong wind debris removal duct 220, and a horizontal conveyor belt 230; the vibration conveying device 210 is configured to drive the horizontal conveyor belt 230 to move and to cause the horizontal conveyor belt 230 to vibrate in the X and Y directions; the bottom strong wind debris removal duct 220 is disposed at the bottom of the horizontal conveyor belt 230 and is configured to blow debris from the bottom of the horizontal conveyor belt 230 toward the tobacco debris collection device 300; and a debris screening hole array 231 is formed in the horizontal conveyor belt 230.

[0060] The vibration conveying device 210 mainly provides vibration functions in the X and Y directions and the transmission function of tobacco shreds in the Y direction for the primary vibration screening structure. To ensure the stability and uniformity of vibration, the two vibration conveying devices 210 are respectively arranged at the front and rear ends of the tobacco shred vibration screening conveyor belt 200. The bottom strong wind debris removal duct 220 can provide strong wind to blow away the debris at the bottom of the horizontal conveyor belt 230. The blown debris enters the tobacco shred debris collection device 300.

[0061] In some embodiments, the vibration transmission device 210 includes a spring 211, a linear bearing side mounting base 212, an X-direction degree-of-freedom linear bearing 213, a linear bearing housing 214, a keyed drive shaft 215, a roller side mounting surface 216, a roller with a rectangular slot inside the shaft hole 217, an X-direction vibration source motor 218, an eccentric rotating disk 219, a universal coupling shaft end mounting end 2110, a cross universal coupling 2111, a motor mounting base 2112, a stepper motor with a jerky forward movement 2113, a universal coupling motor end mounting base 2114, a keyed drive shaft end mounting base 2115, an L-shaped motor mounting base 2116, and an X-direction vibration source mounting base 2117; One end of the spring 211 is fixed to the side of the linear bearing side mounting base 212, and the other end of the spring 211 is in contact with the roller side mounting surface 216 under pressure. The end of the linear bearing side mounting base 212 away from the spring 211 is fixedly connected to the outer ring of the X-direction degree-of-freedom linear bearing 213, so that the linear bearing side mounting base 212 can move in the X direction. The inner ring of the X-direction degree-of-freedom linear bearing 213 is transitionally connected to the keyed drive shaft 215. The bottom of the linear bearing housing 214 is fixed to the protective cover 100, and the X-direction degree-of-freedom linear bearing 213 is fixed to the linear bearing housing 214. The keyed drive shaft 215 is axially provided with a protruding rectangular key, which passes through... A rectangular slotted roller 217 with a clearance fit is provided between the rectangular slotted roller 217 and the shaft hole, allowing the roller 217 to move in the X direction. A roller-side fixing surface 216 is located at the end of the roller 217. The bottom of the X-direction vibration source motor 218 is fixed to the L-shaped motor mounting base 2116, and the motor shaft of the X-direction vibration source motor 218 is connected to the eccentric rotating disk 219. A universal coupling shaft end fixing end 2110, a cross universal coupling 2111, and a universal coupling motor end fixing seat 2114 are connected sequentially. The universal coupling shaft end fixing end 2110 is connected to a keyed drive shaft end fixing seat 2115. 2115 is connected to the keyed drive shaft 215, and the universal coupling motor end mounting base 2114 is connected to the stuttering forward stepper motor 2113; the bottom of the motor mounting base 2112 is connected to the bottom of the protective cover 100, and the top of the motor mounting base 2112 fixes the stuttering forward stepper motor 2113; the stuttering forward stepper motor 2113 is configured to drive the horizontal conveyor belt 230 to stutter forward in the Y direction; one end of the L-shaped motor mounting base 2116 is connected to the X-direction vibration source mounting base 2117; the X-direction vibration source mounting base 2117 is connected to the outer ring of the X-direction degree of freedom linear bearing 213, so that the X-direction vibration source mounting base 2117 can move in the X direction.

[0062] Spring 211 is a metal spring. One end of spring 211 is welded and fixed to the side end of linear bearing side mounting seat 212, and the other end of spring 211 is in contact with and supported by the roller side mounting surface 216. One end of linear bearing side mounting seat 212 is welded and fixed to spring 211, and the other end of linear bearing side mounting seat 212 is fixed to the outer ring bolt of X-direction degree-of-freedom linear bearing 213 by bolts. Linear bearing side mounting seat 212 can slide along the X-direction. One X-direction degree-of-freedom linear bearing 213 is installed on each side. Each X-direction degree-of-freedom linear bearing 213 includes an inner ring, balls, and an outer ring. The outer ring can slide along the X-direction, and the inner ring is transitionally connected to the keyed drive shaft 215. Linear bearing seat 214 is bolted to X-direction. A linear bearing 213 with directional freedom is bolted to the bottom of a linear bearing housing 214 and a protective cover 100. A keyed drive shaft 215 is a smooth shaft with an axially protruding rectangular key. The rectangular key is clearance-fitted with a roller 217 with a rectangular slot inside the shaft hole via a rectangular slot. The roller 217 has X-direction displacement function. A roller-side fixing surface 216 is bolted to the roller 217, and one side of the roller-side fixing surface 216 is pressurized and positioned by a spring 211. The X-direction vibration source motor 218 is a controllable speed-adjustable motor with a self-locking function. The bottom of the X-direction vibration source motor 218 is bolted to an L-shaped motor mounting base 2116. The rotating shaft is bolted to the eccentric rotating disk 219. During operation, because the motor shaft is located off-center on the side of the eccentric rotating disk 219, dynamic imbalance is easily generated, resulting in vibration at a certain frequency in the X direction. As the speed of the X-direction vibration source motor 218 changes, the vibration frequency in the X direction also changes. The eccentric rotating disk 219 has mass adjustment positioning holes. During unbalanced rotation, the mass of the eccentric rotating disk 219 can be adjusted by disassembling and assembling the counterweight plate to regulate the magnitude of the eccentric imbalance during rotation, thereby adjusting the vibration amplitude. During vibration, the roller 217 with rectangular slots inside the shaft hole overcomes the elastic force of the spring 211 relative to the keyed drive shaft 215 in the X direction. The motion can cause the horizontal conveyor belt 230 to vibrate in the X direction, thereby realizing the function of vibrating and screening the tobacco in the X direction. The universal coupling shaft end fixed end 2110, the cross universal coupling 2111 and the universal coupling motor end fixed seat 2114 are tightly connected by bolts. One end of the cross universal coupling 2111 is fastened to the keyed drive shaft end fixed seat 2115 by bolts through the universal coupling shaft end fixed end 2110, and the other end of the cross universal coupling 2111 is tightly connected to the stepper motor 2113 through the universal coupling motor end fixed seat 2114. The cross universal coupling 2111 can provide X-direction displacement compensation for the X-direction vibration process, thereby realizing the X-direction vibration effect.The bottom of the motor mounting bracket 2112 is bolted to the bottom of the protective cover 100, and the top of the motor mounting bracket 2112 is bolted to the stepper motor 2113. The motor mounting bracket 2112 mainly serves as a transition and buffer. The stepper motor 2113 has a jerky forward movement function, driving the horizontal conveyor belt 230 to move forward jerky in the Y direction, which can cause the horizontal conveyor belt 230 to vibrate in the Y direction. The keyed drive shaft end mounting bracket 2115 connects the keyed drive shaft 215 to the keyed drive shaft end with bolts. The fixed base 2115 is tightly connected and fixed; one end of the L-shaped motor mounting base 2116 is bolted to the X-direction vibration source motor 218, and the other end of the L-shaped motor mounting base 2116 is bolted to the X-direction vibration source fixed base 2117; the X-direction vibration source fixed base 2117 is bolted to the outer ring of the X-direction degree-of-freedom linear bearing 213, and the X-direction vibration source fixed base 2117 has the freedom to slide along the X-direction; the horizontal conveyor belt 230 is a toothed drive belt pulley structure, and the horizontal conveyor belt 230 is driven by the gear teeth on the roller 217 with rectangular slots inside the shaft hole.

[0063] In some embodiments, the air separation and debris removal device 400 includes a tobacco collection hole 410, a debris collection container 420, a fan 430, and a pitch adjustment fixing seat 440; the tobacco collection hole 410 is located near the end of the tobacco vibrating screening conveyor belt 200; the debris collection container 420 is located on the side of the tobacco collection hole 410 away from the air guide of the tobacco vibrating screening conveyor belt 200; the pitch adjustment fixing seat 440 is located at the bottom of the end of the tobacco vibrating screening conveyor belt 200; the fan 430 is located on the pitch adjustment fixing seat 440, the blowing pitch angle of the fan 430 is adjustable, and the blowing direction of the fan 430 extends from the tobacco collection hole 410 to the debris collection container 420.

[0064] Under the action of the air blown by the blower 430, the debris is blown to the far end, and the purified tobacco shreds at the near end enter the steep slope conveyor belt 500 through the tobacco shred collection hole 410 and are transported to the next process; the debris collection container 420 is a bottom-sealed container, which is specially used to collect the debris blown to the far end, thereby improving the quality of the purified tobacco shreds; the wind speed of the blower 430 is adjustable, and the blower 430 is bolted to the pitch adjustment fixing seat 440, so that the blower 430 has the function of pitch angle adjustment, which can meet the debris removal requirements of different tobacco shreds.

[0065] This invention provides a novel two-stage debris removal system for purifying and storing tobacco shreds. It proposes a technology for removing non-magnetic debris and designs a vibrating conveyor belt 200 capable of screening tobacco shreds in both the X and Y directions, as well as an air-separating debris removal device 400. This system achieves two-stage purification of the tobacco shreds, effectively improving tobacco quality, reducing harmful gases produced during combustion, and solving the problem of ineffective removal of non-magnetic debris. It provides controllable and adjustable frequency vibration in both the X and Y directions, and tobacco shred transport in the Y direction. Under bidirectional vibration conditions, it can quickly and effectively remove debris from the debris removal aperture array in the tobacco shreds, thereby improving tobacco quality. The motor shaft is located off-center on the side of the eccentric rotating disk 219, which easily leads to dynamic imbalance, resulting in vibration at a certain frequency in the X direction. As the speed of the X-direction vibration source motor 218 changes, the vibration frequency in the X direction also changes. The eccentric rotating disk 219 has mass adjustment positioning holes. During unbalanced rotation, the mass of the eccentric rotating disk 219 can be adjusted by disassembling and assembling the counterweight plate to adjust the magnitude of the eccentric imbalance during rotation, thereby achieving the function of adjusting the vibration amplitude. During vibration, the roller 217 with rectangular slots inside the shaft hole will overcome the elastic force of the spring 211 and move relative to the keyed drive shaft 215 in the X direction, which can cause the horizontal conveyor belt 230 to vibrate in the X direction, thereby realizing the function of vibrating and screening tobacco in the X direction. The tobacco shreds that have undergone primary purification are conveyed by the tobacco shreds vibrating screening conveyor belt 200 to the air classifier and desiccant device 400. The blower 430 separates the desiccant and tobacco shreds in the primary purification process, achieving the purpose of secondary purification of the tobacco shreds. At the same time, the wind speed of the blower 430 is adjustable. The blower 430 is bolted to the pitch adjustment fixing seat 440, so that the blower 430 has the function of pitch angle adjustment, which can meet the desiccant removal requirements of different tobacco shreds.
