[0001] The invention relates to the technical field of tobacco recycling, in particular to a tobacco recycling spiral oscillation impurity removal device. Background Art

[0002] During the production process of cigarettes, there are multiple layers of progressive standards for quality control of finished cigarettes. For example, the quality of tobacco is first inspected, and then the quality of other aspects such as cigarette paper, filter, and packaging is inspected. When the quality acceptance except for tobacco fails, the tobacco in the cigarette will be discarded directly, which will result in a great waste. Therefore, the tobacco in discarded cigarettes with qualified quality can be recycled.

[0003] During recycling, the tobacco, filter, cigarette paper and other structures are peeled off from the cigarettes. During the peeling process, the tobacco is easily mixed with impurities such as cigarette paper and filter. At present, it is separated by an oscillating screen. However, when the conventional oscillating screen is used for impurity removal, the tobacco is often accumulated on the outer edge of the oscillating screen, and the screening effect of tobacco and impurities is not good.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In order to solve the above problems, the present invention proposes a tobacco recycling spiral oscillation impurity removal device, which is used to remove impurities from the recycled tobacco and separate the impurities from the tobacco. Figure 1 , Figure 2 , Figure 3 , Figure 4, mainly comprising a spirally oscillating sieve plate 1, a discharge port 9 is arranged just above the center of the sieve plate 1, a sieve plate 2 is arranged on the upper layer of the sieve plate 1, a central diffusion type sieve hole array is arranged in the central area of ​​the sieve plate 2, and an annular diffusion type sieve hole array is arranged in the peripheral area of ​​the sieve plate 2; a spirally diffused baffle 4 is fixedly connected to the upper side of the sieve plate 2, the inner end of the baffle 4 is located on the outer side of the sieve hole array in the central area of ​​the sieve plate 2, and the outer end of the baffle 4 is fixedly connected to the upper side wall of the sieve plate 1, so that the material falling into the center of the sieve plate 2 can be screened by the sieve hole array along the path formed by the spiral interval of the baffle 4 and fall into the lower layer of the sieve plate 1.

[0023] It should be clear that the impurity removal device of the present invention also includes a driving device 5 for driving the upper sieve plate 1 to perform spiral oscillation. In the embodiment of the present invention, the driving device 5 is a cylindrical structure with a groove inside, and an annular abutment plate is provided at the upper port. A connecting shaft 8 is provided at the center of the bottom of the sieve plate 1 to be transmission-connected with the output end of the driving device 5. A plurality of springs 7 are arranged between the bottom wall edge of the sieve plate 1 and the annular abutment plate to balance and stabilize the oscillation amplitude of the sieve plate 1.

[0024] In the embodiment of the present invention, the material includes tobacco and other cigarette materials (such as filter rods, packaging paper, etc.), and impurity removal is to separate tobacco from other cigarette materials, and recover tobacco of qualified quality for secondary use. Based on the peeling operation during cigarette recovery, the size of other cigarette materials is larger than loose tobacco, so after opening the sieve plate 2 in the sieve plate 1 with a suitable aperture 3, only loose tobacco is allowed to fall, and the sundries mixed therein cannot pass through the sieve hole 3.

[0025] The sieve plate 1 of the present invention is bounded by the sieve plate 2, with the upper side being the upper layer and the lower side being the lower layer. The debris is always on the sieve plate 2, i.e. the upper layer; the tobacco shreds gradually loosen and fall through the sieve holes 3 to the lower layer.

[0026] In one embodiment, a debris outlet 12 is provided at the rear side of the fixed position of the outer end of the baffle 4 and the upper side wall of the sieve plate 1, and the end of the path formed by the spiral spacing of the baffle 4 is connected to the debris outlet 12, so that the material entering the center of the sieve plate 1 from the discharge port 9 is discharged from the sieve plate 1 after a complete oscillation screening path. A debris box 13 can be provided at the lower side of the end of the debris outlet 12 to collect debris. It is understandable that the debris outlet 12 can be provided with an extended structure tilted downward to facilitate the collection of debris.

[0027] In one embodiment, the tobacco shreds falling into the lower layer can be collected by the recovery machine 6. If necessary, the bottom wall of the sieve plate 1 can be designed according to the spiral oscillation of the sieve plate 1 so that the tobacco shreds are concentrated at one point of the side wall, which is convenient for the tobacco shreds to be discharged and collected to the outside. The lower side wall of the sieve plate 1 can be provided with a material outlet 11, which is connected to the recovery port of the recovery machine 6, so that the material falling to the lower layer of the sieve plate 1 can be recovered by the recovery machine 6.

[0028] The recycling machine 6 can be a negative pressure machine to suck and collect the materials accumulated on the side wall of the lower layer. The recycling machine 6 can be connected to the material outlet 11 through a soft channel, so that the recycling machine 6 does not need to vibrate synchronously with the sieve plate 1, which can not only reduce the load of the driving device 5, but also help to stabilize the spiral oscillation stability of the sieve plate 1.

[0029] The recycling machine 6 is provided with an outlet 61 , and a material box 62 is provided directly below the outlet 61 , so that the materials recycled by the recycling machine 6 can be accumulated in the material box 62 .

[0030] In the embodiment of the present invention, the sieve plate 2 is provided with sieve holes 3, which include strip holes and round holes. When the sieve holes 3 are located in different areas on the sieve plate 2, the types and postures of the sieve holes 3 are also different, and the arrays formed by the sieve holes 3 are also different. Please refer to Figure 2 , Figure 3 Based on the array form of the sieve holes 3, the sieve hole array on the sieve plate 2 can be regionally divided into an annular array area 31, a diffusion array area 32, and a central array area 33. It can be understood that the size of the strip holes at any position in the present invention can be consistent, and there is only a change in posture.

[0031] In an implementable embodiment, the diffusion array area 32 corresponds to the central area of ​​the sieve plate 2, the sieve holes 3 therein are strip holes, and the sieve hole array is a central diffusion type. Specifically, a plurality of strip holes are arranged obliquely and surround the center of the sieve plate 2 to form a circular array, and a plurality of circular arrays are coaxially arranged with the center of the sieve plate 2 and the inclination angle of the strip holes in the circular array gradually increases, thereby forming a central diffusion type sieve hole array.

[0032] The central array area 33 is located at the center of the diffusion array area 32, and the sieve holes 3 therein are circular holes. The surrounding area of ​​the innermost circular array based on the sieve hole array in the diffusion array area 32 is the basic range, and the sieve holes 3 in the surrounding area are circular holes. Multiple circular holes can be evenly distributed in the surrounding area.

[0033] It can be understood that the discharge port 9 is located above the center of the sieve plate 1. When the material falls, it directly falls into the center of the sieve plate 2. The central array area 33 can first contact the tobacco, but the tobacco at this time is mostly in a clumping state and is not fully loose; with the spiral oscillation of the sieve plate 1, the accumulated tobacco diffuses to the surroundings along the sieve hole array in the diffusion array area 32, gradually enters the spiral interval of the baffle 4, and continues to oscillate and screen along the path formed by the spiral interval; in this process, the clumping tobacco gradually loosens and falls to the lower layer through the sieve holes in the sieve hole array.

[0034] In an implementable embodiment, the annular array area 31 corresponds to the peripheral area of ​​the sieve plate 2, the sieve holes 3 therein are strip holes, and the sieve hole array is an annular diffusion type. Specifically, the sieve holes 3 in the peripheral area of ​​the sieve plate 2 are strip holes, and the head and tail of the strip holes correspond to a circular array with the center of the sieve plate 2 as the center of the circle, and multiple circular arrays are coaxially arranged with the center of the sieve plate 2 to form an annular diffusion type sieve hole array.

[0035] It can be understood that when tobacco and debris enter the annular array area 31, they can be continuously vibrated and screened along the path formed by the spiral intervals, fully vibrating the clumped tobacco and debris adhered to the tobacco, loosening the tobacco so that it is easier to fall through the sieve holes 3 to the lower layer and separate from the debris.

[0036] It should be clear that the spiral oscillation direction of the sieve plate 1 of the present invention matches the spiral direction of the baffle 4, and can be adjusted according to actual production conditions so that the material can run outward along the spiral interval, effectively extending the oscillation screening path.

[0037] Based on the effective diffusibility of the material, the impurity removal device of the present invention can be continuously operated to remove impurities from the material when in use, and can effectively improve the impurity removal efficiency; however, the falling speed of the material should be controlled.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
