Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, and in particular to a device for removing impurities from tobacco filaments. Background Technology

[0002] Tobacco filament impurity removal refers to the process of removing foreign objects such as sand, metal, plastic, and hemp rope mixed in with tobacco leaves and filaments through screening, air separation, magnetic separation, and other processes during the tobacco processing stage. The purpose is to improve the purity of tobacco raw materials, ensure the safe operation of subsequent equipment, and reduce adverse effects on product quality and smoking taste.

[0003] A search revealed that the document with publication number "CN218048926U" mentions "a utility model discloses an oilseed raw material impurity removal device, including a chassis, a screening box, and a feeding box. A frame is installed at the bottom of the chassis, a screening box is provided inside the chassis, sliders are fixed on both sides of the outer wall of the screening box, slide rails connected to the sliders are provided on both sides of the inner wall of the chassis, and a feeding box is provided at the top of the chassis." In use, when soybean raw materials pass between the baffles inside the fixed plate, the air blown by the fan blows from the gaps between the adjacent baffles towards the opening of the feeding box, thereby quickly discharging light waste such as grass leaves mixed in with the soybean raw materials. Furthermore, the reciprocating motion of the screening box can filter out large granular impurities, allowing the device to classify and remove impurities from soybean raw materials used in oilseed production. When the two sealed doors are opened sequentially, the second motor drives the lead screw to rotate, which in turn drives the scraper to quickly discharge the impurities inside the screening box.

[0004] However, during tobacco processing, tobacco filaments often contain various impurities, such as dust, small leaves, stem fragments, and iron filings. These impurities not only affect the quality of tobacco products but may also damage subsequent processing equipment. Existing impurity removal methods mostly employ manual selection or simple mechanical screening, which are inefficient and difficult to completely remove all types of impurities. In addition, although some automated impurity removal equipment improves efficiency, it has a complex structure, high cost, and varying removal effects on different types of impurities.

[0005] Therefore, we provide a tobacco filament debris removal device to solve the above problems. Utility Model Content

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model, through the setting of a tobacco impurity removal component, activates a vibrating motor after the tobacco raw material slides onto the flat plate, causing the flat plate to vibrate, thus distributing the tobacco strands evenly, reducing their accumulation, and improving impurity removal efficiency. The electrostatic generator causes an electrostatic adsorption effect on the flat plate, attracting lightweight impurities such as dust from the tobacco strands. The heavier tobacco strands, however, naturally slide onto the screening plate. As the tobacco strands fall from the end of the flat plate onto the screening plate, the vibration of the vibrating motor causes the screening plate to vibrate slightly, causing the tobacco strands to slide down the screening plate. Impurities such as small leaves and stems are filtered through the mesh of the screening plate by the vibration and fall into the impurity collection tray below, achieving efficient separation.

[0022] 2. This utility model, by setting up a tobacco impurity removal component, allows tobacco shreds to slide down to the end of the flat plate and pass through a magnetic roller. The height of the magnetic roller is adjusted by a hydraulic pump rod according to the feeding speed and thickness of the tobacco shreds. At this time, a rotary motor drives the magnetic roller to rotate, adsorbing iron filings and impurities in the tobacco shreds to the surface. They are then scraped off by a scraper into an iron filings trough. When the iron filings trough is full, it can be removed from the mounting frame for cleaning. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 As shown, this utility model provides a technical solution: a tobacco filament debris removal device, including a debris removal body 1, a feeding assembly 2 installed on the upper side of the debris removal body 1, a tobacco debris removal assembly 3 arranged on the inner side of the debris removal body 1, the tobacco debris removal assembly 3 including a driven rotating shaft 301 installed on the inner side of the debris removal body 1, a flat plate 302 welded to the upper side of the driven rotating shaft 301, a vibration motor 303 installed on the left side of the flat plate 302, an electrostatic generator 304 installed on the left side of the debris removal body 1, a screening plate 311 arranged on the lower side of the flat plate 302, a debris storage tray 312 arranged on the lower side of the screening plate 311, and a plastic cleaning assembly 4 installed at the lower left end of the debris removal body 1.

[0031] Furthermore, the feeding assembly 2 includes a feeding hopper 201 welded to the upper side of the impurity removal machine body 1. A slider 202 is provided on the inner side of the feeding hopper 201. A limiting plate 203 is connected to the surface groove of the slider 202. The limiting plate 203 and the feeding hopper 201 together form a limiting structure. When needed, the tobacco raw material is poured into the feeding hopper 201. Then, according to the feeding speed, the limiting plate 203 moves inward along the slider 202. At this time, under the action of the limiting plate 203, the tobacco raw material slides down into the flat plate 302 at a uniform speed and in layers, avoiding the situation that the thickness is too thick after feeding.

[0032] Furthermore, the electrostatic generator 304 is electrically connected to the flat plate 302, which is tilted at a 20-degree angle. When needed, the electrostatic generator 304 will cause the flat plate 302 to have an electrostatic adsorption effect, which will cause light impurities in the tobacco strands, such as dust, to be adsorbed onto the flat plate 302. The tobacco strands are heavier and will naturally slide down to the screening plate 311.

[0033] Furthermore, a hydraulic pump rod 305 is welded to the upper right side of the flat plate 302. A magnetic suction roller 306 is installed in the middle of the hydraulic pump rod 305. A rotary motor 307 is connected to the outer side of the magnetic suction roller 306. A mounting bracket 308 is installed at the front end of the hydraulic pump rod 305. A chip groove 309 is connected to the inner side of the mounting bracket 308. A scraper 310 is welded to the upper side of the chip groove 309. The hydraulic pump rod 305 drives the magnetic suction roller 306 to rise and fall, and the rotary motor 307 drives the magnetic suction roller 306 to rotate. The scraper 310 and the magnetic suction roller 306 rotate together. The motor 307 forms a rotating scraper structure. When needed, the tobacco shreds slide down to the end of the flat plate 302 and pass through the magnetic roller 306. The height of the magnetic roller 306 is adjusted by the hydraulic pump rod 305 according to the feeding speed and thickness of the tobacco shreds. At this time, the rotating motor 307 drives the magnetic roller 306 to rotate, adsorbing the iron filings and impurities in the tobacco shreds to the surface. Then, they are scraped off by the scraper 310 into the iron filings trough 309. When the iron filings trough 309 is full, it can be removed from the mounting bracket 308 for cleaning.

[0034] Furthermore, the flat plate 302 and the impurity removal machine body 1 form a rotating structure through the driven rotating shaft 301, and the vibration motor 303 and the driven rotating shaft 301 cooperate with the flat plate 302 to form a vibration structure. When it is needed, after the tobacco raw material slides into the flat plate 302, the vibration motor 303 starts and drives the flat plate 302 to vibrate, so that the tobacco filaments are evenly distributed, reducing the accumulation of tobacco filaments and improving the impurity removal efficiency.

[0035] Furthermore, the screening plate 311 is connected to the impurity removal body 1 by a slot, and the impurity storage tray 312 is located directly below the screening plate 311. The screening plate 311 is inclined at a 35-degree angle. When needed, it slides down from the end of the flat plate 302 and falls onto the screening plate 311. Due to the vibration of the vibration motor 303, the residual vibration will cause the screening plate 311 to vibrate slightly in sync, thereby causing the tobacco shreds to slide down along the screening plate 311. Impurities contained in the tobacco shreds, such as small leaves and stems, are filtered by the mesh of the screening plate 311 due to the vibration and fall into the impurity storage tray 312 below, achieving efficient separation.

[0036] Furthermore, the plastic cleaning component 4 includes a side baffle 401 welded to the left side of the screening plate 311. A dust blowing screen hole 402 is provided in the middle of the side baffle 401, and a blower 403 is installed on the outside of the side baffle 401. The dust blowing screen hole 402 and the blower 403 are connected by a pipe. When the tobacco shreds on the screening plate 311 slide onto the dust blowing screen hole 402 in the middle of the side baffle 401, the blower 403 is activated and strong air is sent into the dust blowing screen hole 402 through the pipe to blow away the light plastic impurities in the tobacco shreds. The side baffles 401 on both sides send the tobacco shreds that may be blown away back into the dust blowing screen hole 402 until the tobacco shreds are sent out.

[0037] Working Principle: When needed, the cleaning machine 1 is placed in the required position. Then, according to the required feeding speed, the limiting plate 203 is adjusted along the slider 202. Once ready, tobacco shreds are poured into the feed hopper 201, and the tobacco shreds fall uniformly onto the spreading plate 302. At this time, the vibrating motor 303 drives the spreading plate 302 to vibrate, and the spreading plate 302 vibrates vertically via the driven rotating shaft 301, shaking the dust onto its surface. The static electricity generated by the electrostatic generator 304 attracts the dust through the spreading plate 302, and the resulting vibration spreads the tobacco shreds on the spreading plate 302 evenly. As the vibration moves, the tobacco shreds slide to the very end of the spreading plate 302. At this point, according to the thickness of the tobacco shreds, the hydraulic pump rod 305 pushes the magnetic roller 306 to adjust its height, while the rotary motor 307 drives the magnetic roller 306 to rotate forward, and the surface of the magnetic roller 306 does not... The magnetic roller 306 directly contacts the surface of the tobacco strands, attracting iron filings. As the roller rotates, the iron filings are scraped off by the scraper 310 and fall into the iron filings groove 309 within the mounting frame 308. The tobacco strands, now adsorbed by the iron filings, then fall onto the screening plate 311. The residual vibration from the vibrating motor 303 continues to vibrate the screening plate 311, causing the tobacco strands to slide off. The tobacco fragments and impurities then fall through the holes into the waste collection tray 312. When the tobacco shreds slide to the very end of the sieve plate 311, they will slide onto the blow-off screen hole 402. At this time, the blower 403 injects gas into the blow-off screen hole 402, and the gas blows the tobacco shreds up. Since the tobacco shreds are heavier and the plastic material is lighter, the tobacco shreds will fall back onto the blow-off screen hole 402, while the plastic material will be blown away. Even if some tobacco shreds drift out, they will be captured again by the side baffle 401. This completes the process of using a tobacco shred debris removal device.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
