Description

Technical Field

[0001] This application relates to the field of tobacco processing technology, and in particular to a material blending system and its corner conveyor device. Background Technology

[0002] In the tobacco industry, the material conveying process during tobacco processing requires the blending of other materials, which is carried out at a 90-degree angle. The blending section employs a "sandwich" blending method, characterized by layering different materials onto the downstream converging conveyor. Key process parameters to ensure include: uniformity of material distribution across each layer (including uniformity in width and conveying direction); consistent placement of each material's tip on the converging conveyor; and consistent width across each layer.

[0003] However, when existing corner conveyor devices deliver ingredients to the main conveyor belt, the tobacco shreds are clumped up on the conveyor belt, making it impossible to accurately and evenly spread the material along a specific width on the downstream conveyor belt.

[0004] When the aforementioned corner conveyor device transfers materials from the upstream conveyor belt to the downstream conveyor belt at a 90° angle, the blending ratio on a portion of the conveyor belt is inaccurate due to the clumps of tobacco laid out. Utility Model Content

[0005] Therefore, it is necessary to provide a material blending system and its corner conveyor device to address the problem that the blending ratio on a certain length of the conveyor belt is inaccurate when the material is transferred from the upstream conveyor belt to the downstream conveyor belt at a 90° angle due to the clumps of tobacco laid out.

[0006] A corner conveyor device, the corner conveyor device comprising:

[0007] The support platform includes a first support plate, a second support plate, and a support frame. Both the first support plate and the second support plate are arc-shaped structures. The first support plate and the second support plate are respectively disposed on both sides of the top surface of the support frame, and the arc-shaped concave surfaces of the first support plate and the second support plate face the same side.

[0008] A conveying assembly includes a first conveyor roller, a second conveyor roller, a conveyor belt, and a drive motor. The first and second conveyor rollers are rotatably connected between a first support plate and a second support plate, with the first and second conveyor rollers located at opposite ends of the first and second support plates, respectively. The conveyor belt is rotatably fitted onto the first and second conveyor rollers. The drive motor drives the second conveyor roller to rotate.

[0009] The material feeding roller assembly is located on the upper side of the conveyor belt. The two ends of the material feeding roller assembly are respectively connected to the first support plate and the second support plate, and can swing relative to the conveyor belt in a first direction, which is the conveying direction of the conveyor belt.

[0010] In the actual conveying process, the aforementioned corner conveyor device drives the second conveyor roller to rotate via a drive motor. Since the conveyor belt is rotatably mounted on the first and second conveyor rollers, and both rollers are rotatably connected between the first and second support plates, with the first and second rollers located at opposite ends of the first and second support plates respectively, the conveyor belt can reciprocate around the first and second conveyor rollers along a first direction. The first and second support plates are respectively located on opposite sides of the top surface of the support frame, with their concave surfaces facing the same side. Therefore, the conveyor belt can rotate along the first and second support plates, i.e., the first direction is an arc direction, thus enabling corner conveying of tobacco shreds. This simplifies the overall layout, effectively utilizes factory space, and makes the overall equipment layout aesthetically pleasing. This application includes a feeding roller assembly located on the upper side of the conveyor belt. The two ends of the feeding roller assembly are connected to the first support plate and the second support plate, respectively, and can swing relative to the conveyor belt in the first direction. In this way, the clumps of tobacco can be dispersed during the swinging process in the first direction, and the height of the tobacco is the distance between the feeding roller assembly and the conveyor belt. This enables the tobacco to be evenly spread from the first conveying mechanism to the second conveying mechanism, ensuring a more accurate blending ratio of tobacco.

[0011] In one embodiment, the corner conveying device further includes a cover, which covers the conveying assembly and is connected to the first support plate and the second support plate. The cover has a discharge hole at one end along the first direction and a feed hole at the top of the other end.

[0012] In one embodiment, the material feeding roller assembly includes a feeding roller, a rotating shaft, and a handle. The rotating shaft passes through the cover, the first support plate, and the second support plate and is movable relative to the support platform along the first direction. The two ends of the handle are respectively connected to the two ends of the rotating shaft extending out of the cover. The feeding roller is sleeved on the rotating shaft and rotates around the axis of the rotating shaft in a second direction, which is the width direction of the conveyor belt.

[0013] In one embodiment, the first support plate, the second support plate, and the two side walls of the cover along the second direction are all provided with strip-shaped holes along the first direction. The rotating shaft passes through the strip-shaped holes of the second support plate and the two side walls of the cover along the second direction and can move and cooperate with the support platform along the first direction.

[0014] In one embodiment, the handle includes a first connector, a second connector, and a gripping member. The two ends of the rotating shaft extending from the cover are respectively connected to the first connector and the second connector, and the two ends of the gripping member are respectively connected to the first connector and the second connector, so that the gripping member is located at the top of the cover.

[0015] In one embodiment, the corner conveying device further includes a baffle assembly that passes through the cover and is movable with the cover in a third direction, the third direction being the vertical direction.

[0016] In one embodiment, the baffle assembly includes a baffle body and a fixing member. The two ends of the baffle along the second direction are respectively slidably engaged with the two sides of the cover along the second direction. The fixing member passes through the cover and can abut or disabut the baffle. The second direction is the width direction of the conveyor belt.

[0017] In one embodiment, the corner conveying device further includes a plurality of support rollers, the two ends of which are connected to the first support plate and the second support plate respectively. The plurality of support rollers are evenly distributed in a fan shape along the first direction, and the support rollers are located between the conveyor belt and the support frame.

[0018] In one embodiment, the corner conveyor further includes a plurality of cross braces and a support plate, the support plate extending along the first direction, the support plate being connected to the first support plate and the second support plate on both sides along the second direction and located between the annular conveyor belt, the cross braces being disposed along the second direction on the side of the conveyor belt near the support plate, the plurality of cross braces being evenly distributed along the first direction, the second direction being the width direction of the conveyor belt.

[0019] A material blending system, the material blending system comprising: a plurality of first conveying mechanisms, a second conveying mechanism, and a plurality of the aforementioned corner conveying devices;

[0020] Multiple first conveying mechanisms correspond one-to-one with multiple corner conveying devices, and the multiple corner conveying devices are arranged sequentially along the conveying direction of the second conveying mechanism;

[0021] One end of the conveyor belt is used to receive the material from the first conveying mechanism, and the other end is used to feed the material to the second conveying mechanism.

[0022] A material blending system includes: multiple first conveying mechanisms, a second conveying mechanism, and multiple corner conveying devices. The multiple first conveying mechanisms correspond one-to-one with the multiple corner conveying devices, and the corner conveying devices are arranged sequentially along the conveying direction of the second conveying mechanisms. One end of the conveyor belt receives material from the first conveying mechanisms, and the other end feeds material to the second conveying mechanisms.

[0023] In the actual conveying process of the aforementioned material blending system, the drive motor drives the second conveyor roller to rotate. Since the conveyor belt is rotatably mounted on the first and second conveyor rollers, and both the first and second conveyor rollers are rotatably connected between the first and second support plates, and the first and second conveyor rollers are located at opposite ends of the first and second support plates respectively, the conveyor belt can reciprocate around the first and second conveyor rollers along a first direction. The first and second support plates are respectively located on both sides of the top surface of the support frame, with their concave surfaces facing the same side. Therefore, the conveyor belt can rotate along the first and second support plates, i.e., the first direction is an arc direction, thus enabling corner conveying of tobacco shreds. This simplifies the overall layout, effectively utilizes factory space, and makes the overall equipment layout aesthetically pleasing. This application includes a feeding roller assembly located on the upper side of the conveyor belt. The two ends of the feeding roller assembly are connected to the first support plate and the second support plate, respectively, and can swing relative to the conveyor belt in the first direction. In this way, the clumps of tobacco can be dispersed during the swinging process in the first direction, and the height of the tobacco is equal to the distance between the feeding roller assembly and the conveyor belt. This allows the tobacco from multiple first conveying mechanisms to be evenly spread on the second conveying mechanism, ensuring a more accurate blending ratio of multiple layers of tobacco on the second conveying mechanism.

[0048] See Figure 2 , Figure 2 A schematic diagram of the structure of a corner conveying device 10 according to an embodiment of this application is shown. The corner conveying device 10 provided in an embodiment of this application includes: a support platform 100, a conveying assembly 200, and a feeding roller group 300.

[0049] See Figure 1 The corner conveyor device 10 of this application is used to rotate the tobacco shreds on multiple first conveyor mechanisms 20 by 90° and then lay them proportionally onto a second conveyor mechanism 30, wherein the extension direction of the first conveyor mechanism 20 is perpendicular to the extension direction of the second conveyor mechanism 30. A material blending system 1 includes: multiple first conveyor mechanisms 20, a second conveyor mechanism 30, and multiple corner conveyor devices 10. The multiple first conveyor mechanisms 20 correspond one-to-one with the multiple corner conveyor devices 10, and the multiple corner conveyor devices 10 are arranged sequentially along the conveying direction of the second conveyor mechanism 30. One end of the conveyor belt 230 is used to receive the material from the first conveyor mechanism 20, and the other end is used to feed the material to the second conveyor mechanism 30.

[0050] Understandably, both the first support plate 110 and the second support plate 120 are arc-shaped structures, meaning they are both support plates extending along an arc direction. One side of the arc-shaped structure is a concave arc surface, and the other side is a convex arc surface.

[0051] In the aforementioned corner conveying device 10, the support platform 100 includes a first support plate 110, a second support plate 120, and a support frame 130. Both the first support plate 110 and the second support plate 120 are arc-shaped structures. The first support plate 110 and the second support plate 120 are respectively disposed on both sides of the top surface of the support frame 130, and the arc-shaped concave surfaces of the first support plate 110 and the second support plate 120 face the same side. The conveying assembly 200 includes a first conveying roller 210, a second conveying roller 220, a conveyor belt 230, and a drive motor. The first conveying roller 210 and the second conveying roller 220 are rotatably connected between the first support plate 110 and the second support plate 120, and the first conveying roller 210 and the second conveying roller 220 are respectively located at both ends between the first support plate 110 and the second support plate 120. Figure 4The conveyor belt 230 is rotatably mounted on the first conveyor roller 210 and the second conveyor roller 220. The drive motor is used to drive the second conveyor roller 220 to rotate. The feeding roller group 300 is located on the upper side of the conveyor belt 230. The two ends of the feeding roller group 300 are respectively connected to the first support plate 110 and the second support plate 120, and can swing relative to the conveyor belt 230 along the first direction OX, which is the conveying direction of the conveyor belt 230.

[0052] In the actual conveying process, the aforementioned corner conveying device 10 drives the second conveying roller 220 to rotate via a drive motor. Since the conveyor belt 230 is rotatably mounted on the first conveying roller 210 and the second conveying roller 220, and both the first and second conveying rollers 210 and 220 are rotatably connected between the first support plate 110 and the second support plate 120, and the first and second conveying rollers 210 and 220 are located at opposite ends of the first and second support plates 110 and 120 respectively, the conveyor belt 230 can reciprocate along the first direction OX around the first conveying roller 210 and the second conveying roller 220. The first support plate 110 and the second support plate 120 are respectively located on both sides of the top surface of the support frame 130, with their concave surfaces facing the same side. Therefore, the conveyor belt 230 can rotate along the first support plate 110 and the second support plate 120, i.e., the first direction OX is an arc direction, thus enabling corner conveying of tobacco shreds. This simplifies the overall layout, effectively utilizes factory space, and makes the overall equipment layout aesthetically pleasing. This application provides a feeding roller assembly 300 located on the upper side of the conveyor belt 230. The two ends of the feeding roller assembly 300 are connected to the first support plate 110 and the second support plate 120 respectively, and can swing relative to the conveyor belt 230 in the first direction OX. In this way, the clumps of tobacco can be dispersed during the swinging in the first direction OX, and the height of the tobacco is the distance between the feeding roller assembly 300 and the conveyor belt 230. This allows the tobacco to be evenly spread from the first conveying mechanism 20 to the second conveying mechanism 30, ensuring a more accurate blending ratio of tobacco.

[0053] See Figure 2 In one embodiment, the corner conveyor 10 further includes a frame 800, with a support frame 130 disposed on top of the frame 800.

[0054] See Figure 2 and Figure 3In one embodiment, the corner conveyor 10 further includes a cover 400, which covers the conveyor assembly 200 and is connected to the first support plate 110 and the second support plate 120. The cover 400 has a discharge hole 410 at one end along the first direction OX, and a feed hole 420 at the top of the other end. In this embodiment, the height of the first conveyor 20 is higher than that of the corner conveyor 10 of this application, and the height of the discharge hole 410 is higher than that of the second conveyor 30. Therefore, when the first conveyor 20 conveys tobacco to one end of the corner conveyor 10, the tobacco falls into the feed hole 420, thereby reaching the conveyor belt 230, being conveyed via the conveyor belt 230 to the discharge hole 410, and then, after exiting the discharge hole 410, the tobacco falls into the second conveyor 30, thus completing the layered blending of tobacco from multiple first conveyors 20 and tobacco upstream of the second conveyor 30.

[0055] See Figure 2 and Figure 5 In one embodiment, the material feeding roller assembly 300 includes a feeding roller 310, a rotating shaft 320, and a handle 330. The rotating shaft 320 passes through the cover 400, the first support plate 110, and the second support plate 120 and is movable relative to the support platform 100 along the first direction OX. The two ends of the handle 330 are respectively connected to the two ends of the rotating shaft 320 extending out of the cover 400. The feeding roller 310 is sleeved on the rotating shaft 320 and rotates around the axis of the rotating shaft 320 in a second direction, which is the width direction of the conveyor belt 230.

[0056] See Figure 2 and Figure 5 In this embodiment, the handle 330 drives the rotating shaft 320 to swing along the first direction OX, thereby driving the agitator roller 310 to swing along the first direction OX. During the swinging process, the agitator roller 310 rubs against the tobacco and disperses the tobacco while rotating during the agitation process to prevent damage to the tobacco.

[0057] See Figure 2 and Figure 5 In one embodiment, the first support plate 110, the second support plate 120, and the cover 400 all have strip holes 110a along the first direction OX on both side walls along the second direction. The rotating shaft 320 passes through the strip holes 110a on the second support plate 120 and the cover 400 along the second direction and can move and cooperate with the support platform 100 along the first direction OX, thereby realizing the swing of the roller 310 along the first direction OX.

[0058] In other embodiments, a moving component can also be provided on the first support plate 110 and the second support plate 120. The moving component drives the rotating shaft 320 to swing along the first direction OX and move closer to or away from the conveyor belt 230 along the third direction OZ, thereby enabling the tobacco shreds to be dispersed into different thicknesses to adjust the tobacco shred blending ratio.

[0059] See Figure 2 and Figure 3 In one embodiment, the handle 330 includes a first connector 331, a second connector 332, and a gripping member 333. The two ends of the rotating shaft 320 extending from the cover 400 are connected to the first connector 331 and the second connector 332, respectively. The two ends of the gripping member 333 are also connected to the first connector 331 and the second connector 332, so that the gripping member 333 is located at the top of the cover 400. By gripping the gripping member 333, the first connector 331 and the second connector 332 can be swung along the first direction OX, which in turn causes the rotating shaft 320 to swung along the first direction OX, ultimately causing the agitator roller 310 to swung along the first direction OX to disperse the tobacco.

[0060] Preferably, the corner conveying device 10 further includes two protective covers 630, which are respectively covered by the strip hole 110a. The first connector 331 and the second connector 332 extend out of the corresponding protective cover 630. The protective covers 630 prevent the tobacco inside the cover 400 from leaking out of the strip hole 110a, making the conveying process more airtight.

[0061] See Figure 2 In one embodiment, the corner conveying device 10 further includes a baffle assembly 500, which passes through the cover 400 and is movable with the cover 400 along a third direction OZ, where the third direction OZ is the vertical direction.

[0062] See Figure 2 In one embodiment, the baffle assembly 500 includes a baffle body 510 and a fixing member. The two ends of the baffle along the second direction are respectively slidably engaged with the two sides of the cover 400 along the second direction. The fixing member passes through the cover 400 and can abut or release from the baffle.

[0063] Specifically, the baffle assembly 500 also includes a first sliding part and a second sliding part. The first sliding part is disposed on both sides of the cover 400 along the second direction, and the two ends of the baffle along the second direction slide in cooperation with the first sliding part and the second sliding part along the third direction OZ.

[0064] Preferably, the first sliding part and the second sliding part can be a slide rail, a slide groove or a linear bearing, or other types of components, to drive the baffle to move closer to or away from the conveyor belt 230 along the third direction OZ, so as to change the thickness of the tobacco shreds, thereby realizing the change of the tobacco shred blending ratio. Specifically, the baffle assembly 500 is located on the side of the feeding roller group 300 near the feed hole 420.

[0065] See Figure 2 and Figure 3 In one embodiment, the corner conveyor 10 further includes a plurality of support rollers 600. The two ends of the support rollers 600 are connected to the first support plate 110 and the second support plate 120, respectively. The plurality of support rollers 600 are evenly distributed in a fan shape along the first direction OX. The support rollers 600 are located between the conveyor belt 230 and the support frame 130, thereby supporting the side of the conveyor belt 230 close to the support plate by the plurality of support rollers 600, preventing the conveyor belt 230 from deforming in the length direction due to gravity, which would cause the conveyor belt 230 to loosen along the first direction OX.

[0066] See Figure 2 and Figure 5 In one embodiment, the corner conveyor 10 further includes multiple cross braces 610 and a support plate 620. The support plate 620 extends along a first direction OX, and its two sides along a second direction are connected to a first support plate 110 and a second support plate 120 respectively, and are located between the annular conveyor belt 230. The cross braces 610 are arranged along the second direction on the side of the conveyor belt 230 near the support plate 620. The multiple cross braces 610 are evenly distributed along the first direction OX, and the second direction is the width direction of the conveyor belt 230. In this application, by setting cross braces, the conveyor belt 230 is tightened along the second direction, thereby ensuring that the conveyor belt 230 can be evenly laid with tobacco along the second direction, and preventing the tobacco from accumulating in the depressions in the second direction due to the slack of the conveyor belt 230 along the second direction. By setting the support plate 620, the upper and lower layers of the annular conveyor belt 230 are separated, and the support plate 620 can support the upper layer of the annular conveyor belt 230, preventing the conveyor belt 230 from slack along the first direction OX.

[0067] See Figure 2 and Figure 5 In one embodiment, the corner conveyor 10 further includes a first track 700 and a second track 710. The two ends of the cross brace extend out of the conveyor belt 230. The first support plate 110 is provided with the first track 700 at both ends along the third direction OZ, and the second support plate 120 is provided with the second track 710 at both ends along the third direction OZ. The two ends of the cross brace slide in cooperation with the first track 700 and the second track 710 along the first direction OX. The third direction OZ is vertical, so that the cross brace can move stably along the first direction OX through the first track 700 and the second track 710.

[0068] See Figure 6 Specifically, the conveyor belt 230 has multiple positioning holes 230a along the first direction OX for mounting cross braces 610. Bearings are mounted at both ends of the cross braces 610, and these bearings are in rolling engagement within the first track 700 or the second track 710. The positioning holes 230a are located on the side of the conveyor belt along the second direction near the first support plate 110. Fasteners are inserted through the positioning holes 230a and connected to the cross braces 610 to connect the cross braces to the conveyor belt 230. The first support plate 110 is an outer ring support plate, with a length greater than that of the second support plate 120. The arc length of the first support plate 110 is 6000-7000 mm, and its radius is 2000-2100 mm. The arc length of the second support plate 120 is 3000-4000 mm, and its radius is 1000-1100 mm. The width of the conveyor belt 230 along the second direction is 900-1000 mm. (See reference...) Figure 5 The conveyor belt 230 has a flat unfolding angle of 179°-181°, and an angle of 89.5°-90.5° after being fitted onto the first conveyor roller 210 and the second conveyor roller 220. The minimum distance between the center of the positioning hole 230a and the first support plate 110 is 20-24mm, the spacing between two adjacent positioning holes 230a is 70-72mm, the number of positioning holes 230a is 80-90, and the diameter of the positioning holes 230a is 7-10mm.

[0069] See Figure 1 A material blending system 1 includes: multiple first conveying mechanisms 20, multiple second conveying mechanisms 30, and multiple corner conveying devices 10. The multiple first conveying mechanisms 20 correspond one-to-one with the multiple corner conveying devices 10, and the multiple corner conveying devices 10 are arranged sequentially along the conveying direction of the second conveying mechanisms 30. One end of the conveyor belt 230 is used to receive material from the first conveying mechanisms 20, and the other end is used to feed material to the second conveying mechanisms 30.

[0070] In the actual conveying process of the aforementioned material blending system 1, the drive motor drives the second conveyor roller 220 to rotate. Since the conveyor belt 230 is rotatably mounted on the first conveyor roller 210 and the second conveyor roller 220, and both the first and second conveyor rollers 210 and 220 are rotatably connected between the first support plate 110 and the second support plate 120, and the first and second conveyor rollers 210 and 220 are respectively located at the two ends between the first and second support plates 110 and 120, the conveyor belt 230 can reciprocate along the first direction OX around the first conveyor roller 210 and the second conveyor roller 220. The first support plate 110 and the second support plate 120 are respectively located on both sides of the top surface of the support frame 130, and the arc-shaped concave surfaces of the first and second support plates 110 and 120 face the same side. Therefore, the conveyor belt 230 can rotate along the first and second support plates 110 and 120, i.e., the first direction OX is an arc direction, thereby enabling the corner conveying of tobacco shreds, simplifying the overall layout, effectively utilizing factory space, and making the overall equipment layout aesthetically pleasing. This application provides a feeding roller group 300 located on the upper side of the conveyor belt 230. The two ends of the feeding roller group 300 are respectively connected to the first support plate 110 and the second support plate 120, and can swing relative to the conveyor belt 230 in the first direction OX. In this way, the clump of tobacco can be dispersed during the swing in the first direction OX, and the height of the tobacco is the distance between the feeding roller group 300 and the conveyor belt 230. This enables the tobacco from multiple first conveying mechanisms 20 to be evenly spread on the second conveying mechanism 30, ensuring a more accurate blending ratio of multiple layers of tobacco on the second conveying mechanism 30.
