Description

Technical Field

[0001] This invention relates to the field of waste smoke treatment equipment technology, and in particular to a material sorting device. Background Technology

[0002] During the cigarette rolling process, a certain amount of waste cigarettes with substandard rolling or packaging quality will be generated. These waste cigarettes need to be separated from the cigarette materials by waste cigarette treatment equipment. Cigarette materials include cigarette paper, filter rod core, frame paper, aluminum foil, tipping paper, and other non-tobacco debris. Finally, pure, recyclable tobacco is obtained.

[0003] However, in the process of treating waste smoke, there is a type of waste smoke with concentric circles of filter rod core that cannot be fully separated from the tobacco shreds. As a result, the tobacco shreds after purification still contain a large number of concentric circle filter rod cores, making it impossible to directly recycle the tobacco shreds. Instead, they need to be manually removed for secondary separation and purification, which makes the overall process consume a lot of time and manpower. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a material sorting device that can automatically sort materials, separating tobacco shreds and filter rods from the materials. This not only improves the purity of the recycled tobacco shreds but also reduces manual labor and increases production efficiency.

[0005] The technical solution to the problem of this invention is to provide a material sorting device, including a sorting component and a gripping part. The sorting component is provided with a plurality of sorting parts, each sorting part is provided with a gripping part, and a sorting gap is provided between adjacent sorting parts. Each sorting part cooperates with the gripping part to sort the material, so that the tobacco in the material falls into the sorting gap.

[0006] Furthermore, it also includes a sorting area, in which the sorting components are arranged to form a sorting area, and the material drop area is located within the sorting area.

[0007] Furthermore, the sorting assembly also includes multiple positioning seats and multiple driving components. Both ends of each sorting component are rotatably connected to the positioning seats, and the driving components are rotatably connected to the sorting components, so that the driving components drive the sorting components to rotate.

[0008] Furthermore, the material sorting device also includes a support frame, which is used to support the sorting components and is installed in the material drop area. Each sorting component is evenly spaced along the direction of the support frame, and both ends of each sorting component are rotatably connected to the support frame through positioning seats.

[0009] Furthermore, each drive component synchronously and in the same direction drives the rotation of each sub-selection component.

[0010] Furthermore, the width of the sorting gap is greater than the width of the tobacco shreds, and the width of the sorting gap is less than the width of the filter rod in the material.

[0011] Furthermore, the gripping section includes multiple gripping plates, which are continuously laid on the outer periphery of the sorting component. The sides of adjacent gripping plates are joined together, and each gripping plate pushes the filter rods in the material along the arrangement of each sorting component.

[0012] Furthermore, the gripping plate includes a first plate and a second plate, with the sides of the first plate and the second plate joined together, and an included angle between the first plate and the second plate. The outer sides of the first plate and the second plate are respectively connected to the outer periphery of the sorting component.

[0013] Furthermore, the gripping plate is also equipped with multiple gripping blocks, which are evenly spaced and laid on the outer surface of the gripping plate.

[0014] Furthermore, it also includes a first collection component and a second collection component, the first collection component being disposed below each sorting gap, and the second collection component being disposed below the tail end of the sorting component.

[0015] The beneficial effects of this invention are as follows: This invention can automatically sort tobacco shreds in materials, so that the sorted tobacco shreds can be directly recycled and reused, which not only improves work efficiency, but also reduces the workload of workers, and the sorting accuracy is high.

[0016] This invention can also automatically classify and collect the sorted tobacco and filter rods, thereby enabling the sorted tobacco to be centrally recycled and improving work efficiency.

[0017] This invention can also sort other substances by adjusting the spacing between adjacent sorting components, thus expanding its application range. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] First, it should be clarified that the material sorting device of this application is located below the output port of the conveying device used to transport materials. The aforementioned conveying device is prior art, such as a conveyor belt, and belongs to a structure other than the material sorting device of this application. Therefore, the specific structure of the conveying device will not be described in detail in this application.

[0033] It should be noted that this application will use concentric circular nozzle rods as filter rods in the material to explain the usage method and application environment of the material sorting device of this application.

[0034] Please see Figure 1-6 To solve the above problems, the present invention proposes a material sorting device, including a sorting component 1 and a gripping part 2. The sorting component 1 is provided with a plurality of sorting parts 11, each sorting part 11 is provided with a gripping part 2, and a sorting gap is provided between adjacent sorting parts 11. Each sorting part 11 cooperates with the gripping part 2 to sort the material, so that the tobacco in the material falls into the sorting gap.

[0035] Please see Figure 3 In a specific embodiment of this application, the sorting component 1 includes a positioning seat 12, a driving member 13, and multiple sorting members 11. The gap between adjacent sorting members 11 is the sorting gap. Each sorting member 11, in conjunction with the gripping part 2, rolls the tobacco shreds in the material into the sorting gap and transports the filter rod along the arrangement of the sorting members 11. Specifically, the filter rod is lifted by the gripping part 2, which rotates with the corresponding sorting member 11, and then rolled backward. Each sorting member 11 has a positioning seat 12 at both ends and is rotatably connected to the positioning seat 12. One end of each sorting member 11 on the same side is exposed, and the exposed end of each sorting member 11 is connected to a driving member 13, so that each driving member 13 drives the corresponding sorting member 11 to rotate synchronously and in the same direction.

[0036] For example, the sorting component 11 can be a cylindrical roller, the positioning seat 12 can be cuboid, the two ends of the roller are rotatably connected to the positioning seat 12, and one end of the roller is exposed. The exposed end is rotatably connected to the driving component 13, so that the driving component 13 drives the roller to rotate, and each driving component 13 drives the corresponding roller to rotate synchronously and in the same direction. The exposed ends of each roller can all be located on the same side.

[0037] It is understandable that the speed and direction of all drive components 13 can be controlled by devices such as frequency converters, contactors or encoders, so as to achieve the purpose of each drive component 13 driving the corresponding sorting component 11 to rotate synchronously and in the same direction.

[0038] Please see Figure 5 , Figure 7 and Figure 8 In a specific embodiment of this application, the gripping part 2 includes a plurality of gripping plates 21, which are continuously laid on the outer periphery of the sorting member 11. The sides of adjacent gripping plates 21 are joined together, and each gripping plate 21 pushes the filter rods in the material along the arrangement of each sorting member 11. The structure of the gripping plate 21 specifically includes:

[0039] As one possible implementation method, please refer to Figure 7The gripping plate 21 is a single long plate, and multiple long plates are continuously laid on the outer perimeter of the sorting component 11, completely covering the outer perimeter of the sorting component 11, with the sides of adjacent long plates joined together. The length of each long plate is the same as the length of the sorting component 11, and the width of each long plate can be adaptively adjusted according to the actual number of long plates and the perimeter of the sorting component 11.

[0040] For a preferred embodiment, please refer to Figure 8 The gripping plate 21 is a multi-piece combined long plate, composed of at least two narrow plates joined together. The widths of the narrow plates may differ, and adjacent narrow plates are joined at their sides, with an included angle between them. The angle of the included angle can be adjusted adaptively according to actual application requirements. Multiple combined long plates are continuously laid on the outer perimeter of the sorting component 11. Adjacent combined long plates may be spaced apart or continuously arranged without gaps, and the arrangement can be adaptively adjusted based on the number of combined long plates, the number of narrow plates constituting the combined long plates, the joining angle of adjacent narrow plates, and the perimeter of the sorting component 11. The length of each narrow plate is consistent with the length of the sorting component 11, and the width of each narrow plate can be adaptively adjusted according to actual conditions.

[0041] For example, please refer to Figure 5 and Figure 8 The gripping plate 21 can be composed of two narrow plates, including a first plate 211 and a second plate 212. The width of the first plate 211 and the second plate 212 can be the same. The side of the first plate 211 and the side of the second plate 212 are connected together, and there is an included angle between the first plate 211 and the second plate 212, which is 90°. The outer side of the first plate 211 and the outer side of the second plate 212 are respectively connected to the outer periphery of the sorting member 11. Five gripping plates 21 are arranged continuously and evenly spaced on the outer periphery of the sorting member 11.

[0042] Please see Figure 5 and Figure 6 In order to improve the grabbing rate of tobacco shreds, that is, to improve the sorting rate of tobacco shreds, the friction between tobacco shreds and filter rod and grabbing plate 21 is increased respectively. The surface of grabbing plate 21 is also provided with grabbing blocks 22, and multiple grabbing blocks 22 are evenly spaced and laid on the outer surface of grabbing plate 21.

[0043] For example, the gripping block 22 can be a cylindrical protrusion. The outer surface of the gripping plate 21 is covered with multiple uniformly spaced and continuous gripping blocks 22, which increases the friction between the outer surface of the gripping plate 21 and the tobacco and filter rod. This allows the sorting member 11 to work with the gripping plate 21 and the gripping block 22 to roll the tobacco into the sorting gap, while stopping the filter rod outside the sorting gap and rolling it backward.

[0044] Please see Figure 2In a specific embodiment of this application, the sorting gap is the distance between adjacent sorting members 11 with gripping parts 2. The width of the sorting gap is greater than the width of the tobacco shreds and less than the width of the filter rod in the material.

[0045] For example, the width of the tobacco shreds in the material is 0.7mm to 1.2mm, and the diameter of the concentric round nozzle core is 5mm to 8mm. Therefore, the maximum distance between adjacent sorting members 11 with gripping parts 2 on their outer periphery can be 4.5mm, and the minimum distance can be 2mm. Specifically, when the angles of the gripping plates 21 on two adjacent sorting members 11 are opposite each other, the distance between the two sorting members 11 is the minimum distance; when the gaps between the gripping plates 21 on adjacent sorting members 11 are opposite each other, the distance between the two sorting members 11 is the maximum distance.

[0046] It is understandable that the width of the sorting gap is not limited to the above situation and can be adapted according to the substances that need to be sorted.

[0047] Please see Figure 3 and Figure 4 In order to improve the flexibility of the material sorting device of this application and enable the material sorting device of this application to sort different substances other than tobacco and filter rods, the positioning seat 12 and the support frame 3 are detachably fixed, and the positioning seat 12 and the connection between the support frame 3 are provided with adjustment holes 122 in the horizontal direction.

[0048] For example, the positioning seat 12 can be connected to the support frame 3 through two fixing members 121. The positioning seat 12 is provided with two parallel adjustment holes 122 along the horizontal direction. The support frame is also provided with sliding holes that are adapted to the two adjustment holes 122. The two fixing members 121 are connected to the two sliding holes on the support frame through the two adjustment holes 122. The rotational connection between the sorting member 11 and the support frame is provided with a sliding hole that is adapted to the position adjustment range of the sorting member 11, so that the sorting member 11 follows the positioning seat 12 to adjust its position.

[0049] It is understandable that the fastener 121 can be a mechanical part such as a screw or bolt, which can be adapted to the adjustment hole 122 and the sliding hole to achieve the function of detachable fixing.

[0050] Please see Figure 1 and Figure 2 In a specific embodiment of this application, the sorting components 11 are arranged to form a sorting area, and the sorting area is larger than the material drop area. The arrangement of the sorting components 11 includes:

[0051] As one possible implementation, each sorting component 11 is arranged in a single row. Multiple sorting components 11 are arranged in a single row along the horizontal direction to form a sorting area. Each sorting component 11 is arranged in parallel, and a sorting gap is provided between adjacent sorting components 11. Each sorting component 11 rolls the tobacco into the sorting gap, and at the same time, the filter rod runs along the arrangement of each sorting component 11.

[0052] As another possible implementation, each sorting component 11 is arranged in multiple columns, and multiple sorting components 11 are arranged in multiple columns. Each sorting component 11 in the same column forms a sorting column. Each sorting component 11 in the same sorting column is arranged in parallel, and each sorting column forms a sorting area. A partition plate is provided between adjacent sorting columns.

[0053] For example, each sorting component 11 can be arranged in a single row, with 18 sorting components 11 arranged in parallel and evenly spaced. Each sorting component 11 has a positioning seat 12 at both ends and a driving component 13 at one end. Each driving component 13 drives the corresponding sorting component 11 to rotate in the same direction and synchronously.

[0054] Please see Figure 1-3 In a specific embodiment of this application, the material sorting device of this application further includes a support frame 3, which is mounted on the material drop area. The support frame 3 is equipped with a sorting component 1, and the sorting area of ​​the sorting component 1 is larger than the material drop area. Specifically, the range of the multiple sorting components 11 arranged is larger than the material drop area.

[0055] For example, the support frame 3 includes a fixed frame and a fixed plate. The fixed plate is disposed at the top of the fixed frame, and the sorting component 1 is mounted between the two fixed plates. The positioning seats 12 at both ends of the sorting component 11 are respectively disposed on the outer sides of the two fixed plates. Both ends of the sorting component 11 pass through the fixed plate and are rotatably connected to the positioning seats 12. The driving component 13 corresponding to the sorting component 11 is also disposed on the outer side of one of the fixed frames and is rotatably connected to one end of the sorting component 11. The fixed plate does not affect the rotation of the sorting component 11. The fixed plate has an opening in the area below the sorting component 1, so that the tobacco shreds sorted by the sorting component 1 can be collected.

[0056] The specific support methods for support frame 3 include:

[0057] In one possible implementation, one end of the sorting component 1 is positioned below the output port of the output device, and the sorting component 1 is horizontally positioned, with the sorting area of ​​the sorting component 1 being larger than the material drop area. Tobacco and filter rods are sorted and collected by the rotation of each sorting element 11.

[0058] In a preferred embodiment, one end of the sorting component 1 is positioned below the output port of the output device, and the other end of the sorting component 1 is positioned pointing towards the ground, thereby tilting the sorting component 1. Tobacco and filter rods can be sorted and collected by the rotation of each sorting element 11 and their own gravity, achieving dual-power sorting and improving screening efficiency.

[0059] For example, the tilt angle between the sorting component 1 and the horizontal line can be 15°. A support frame 3 is provided at the bottom of the sorting component 1. The sorting area of ​​the sorting component 1 is located at the higher end and is located directly below the output port of the conveying device 5, ensuring that the material can fall directly into the sorting area for sorting. The driving component 13 can drive the sorting component 11 to rotate clockwise, thereby causing the filter rod to roll backward.

[0060] It is understandable that the rotation direction of the drive component 13 driving the sorting component 11 is adaptively adjusted according to the actual situation, specifically taking into account the drop position of the material, the rolling direction, and the arrangement of each sorting component 11.

[0061] Please see Figure 9-11 The specific methods for setting the initial attitude of adjacent sorting components 11 include:

[0062] As one possible implementation, the initial states of adjacent sorting components 11 are different. Possible situations include: First, when running synchronously and in the same direction clockwise, the friction between the filter rod 6 and the gripping blocks 22 at both ends may be too large due to an unsuitable spacing, causing the filter rod 6 to get stuck in the sorting gap. Adjusting to a suitable spacing requires continuous testing. Second, when running synchronously and in the same direction clockwise, the dynamic spacing between adjacent sorting components 11 during rotation may be too large due to an unsuitable spacing, causing the filter rod 6 to fall out of the sorting gap.

[0063] In a preferred embodiment, all sorting components 11 are initially in the same state. In this case, it is only necessary to determine that the maximum distance between the middle parts of adjacent sorting components 11 with gripping parts 2 is less than the filter rod 6 and the minimum distance is greater than the tobacco. Specifically, when the angles of the gripping plates 21 on two adjacent sorting components 11 are opposite each other, the distance between the two sorting components 11 is the minimum distance; when the gaps between the gripping plates 21 on adjacent sorting components 11 are opposite each other, the distance between the two sorting components 11 is the maximum distance.

[0064] Please see Figure 1 In order to classify and collect the sorted tobacco and filter rods, the material sorting component 1 of this application further includes a first collection component 41 and a second collection component 42. The first collection component 41 is located below each sorting gap, and the second collection component 42 is located below the tail end of the sorting component 1.

[0065] Specifically, the first collecting component 41 includes a first guide 411 and a first collecting chamber 412. The first guide 411 is used to receive tobacco falling from the sorting gap and feed the tobacco into the first collecting chamber 412. The first guide 411 is located below the sorting component 1, in the tobacco falling area, and the receiving area of ​​the first guide 411 is larger than the tobacco falling area. The first collecting chamber 412, which has an opening at its upper end, is located below the tail end of the first guide 411, and the opening size of the first collecting chamber 412 is larger than the width of the output port of the first guide 411. The second collection component 42 includes a second guide 421 and a second collection chamber 422. The second guide 421 is used to receive the filter rods transported to the tail end by the sorting component 11 and send the filter rods into the second collection chamber 422. The second guide 421 is located below the tail end of the sorting component 1 and in the drop area of ​​the filter rods. The receiving area of ​​the second guide 421 is larger than the drop area of ​​the filter rods. The second collection chamber 422 is located below the tail end of the second guide 421. The opening size of the second collection chamber 422 is larger than the width of the output port of the second guide 421.

[0066] The specific configuration of the first guide member 411 and the second guide member 421 includes:

[0067] As one possible implementation, the first guide 411 and the second guide 421 are structures without a power source, such as guide plates, cavity structures with openings at the top and bottom ends, etc. The first guide 411 can be inclinedly disposed below the sorting assembly 1, so that tobacco falling from the sorting gap slides from the first guide 411 into the first collection chamber 412 by gravity; the second guide 421 can be inclinedly disposed below the bottom end of the sorting assembly 1, so that the filter rod transported from the sorting assembly 1 to the second guide 421 slides into the second collection chamber 422 by gravity. The inclination angles of the first guide 411 and the second guide 421 can be adaptively adjusted according to actual conditions to ensure that the tobacco and the filter rod can slide into the first collection chamber 412 and the second collection chamber 422 respectively.

[0068] As another possible implementation, the first guide 411 and the second guide 421 are structures with a power source, such as a conveyor belt. The first guide 411 can be inclined or horizontally disposed below the sorting assembly 1, so that tobacco falling from the sorting gap is transported by the first guide 411 to the first collection chamber 412; the second guide 421 can be inclined or horizontally disposed below the tail end of the sorting assembly 1, so that filter rods transported from the sorting assembly 1 to the second guide 421 are transported by the second guide 421 to the second collection chamber 422.

[0069] The above-described contents can be implemented individually or in various combinations, and these variations are all within the protection scope of this invention.
