Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing, in particular to a non-powered tobacco hemp removing mechanism. Background Art

[0002] Tobacco processing refers to a series of processes of handling and processing tobacco leaves to produce tobacco products that can be used for smoking or other purposes. After the tobacco is dried, some hemp ropes, hemp threads and other hemp fibers will be mixed into the tobacco during the picking process. In order to remove the hemp fibers and purify the tobacco, a tobacco hemp fiber removal mechanism is needed to remove some hemp ropes, hemp threads and other hemp fibers contained in the tobacco.

[0003] However, some tobacco hemp removal mechanisms, when used to remove hemp fibers such as hemp fibers and hemp ropes inside tobacco, generally have complex internal components. Furthermore, the internal hemp removal components are typically powered by electricity, which consumes a certain amount of power during the removal process. Furthermore, after removing the hemp fibers, the hemp removal components cannot be disassembled, making the overall operation cumbersome and time-consuming. This lacks a method for removing hemp fibers from tobacco without power. For example, patent number CN207444255U discloses a novel online hemp fiber removal device for threshing and re-roasting, but it still requires power to operate.

[0004] In summary, a new type of unpowered tobacco hemp removal mechanism is urgently needed to solve the above-mentioned shortcomings. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a non-powered tobacco hemp silk removal device, which can adhere some longer hemp silk contained in tobacco leaves and collect them on the outside of the hemp silk removal roller, and the hemp silk in the tobacco will directly drive the hemp silk removal roller to rotate, without the need to set up additional power for the hemp silk removal roller.

[0006] A non-powered tobacco hemp removal device comprises a mounting seat, a lifting mechanism arranged in the mounting seat, and a hemp removal mechanism connected to the driving end of the lifting mechanism; the hemp removal mechanism comprises a first truss connected to the driving end of the lifting mechanism and two first brackets symmetrically arranged at both ends of the first truss and both extending downward, a hemp removal roller is provided between the two first brackets.

[0009] In a feasible embodiment, it further includes two adapter assemblies respectively provided at both ends of the hemp fiber removing roller;

[0010] The adapter assembly includes a connecting shaft arranged in the slot and an inner shaft connected to one end of the connecting shaft; both ends of the hemp removing roller are provided with inner shaft openings extending into the interior of the hemp removing roller and rotatably connected to the corresponding inner shaft.

[0011] In a feasible embodiment, the hemp fiber removal roller is provided with a plurality of hemp fiber removal sheets which are evenly spaced and extend in the same direction as the hemp fiber removal roller.

[0012] In a feasible embodiment, a plurality of flax sticking balls are provided on the flax removing sheet.

[0013] In a feasible embodiment, the lifting mechanism includes two driving members symmetrically arranged in the mounting seat, a movable rod arranged between the driving shafts of the two driving members and slidably connected thereto, and a plurality of connecting rods arranged below the movable rod and passing through the second truss to be connected to the first truss.

[0014] In a feasible embodiment, the lifting mechanism further includes a transmission rod, which is synchronously and rotatably connected to the driving shafts of the two driving members through gears; and a rotating handle is provided at one end of the transmission rod.

[0015] In a feasible embodiment, two first bevel gears are provided on the transmission rod; and a second bevel gear meshing with the corresponding first bevel gears is provided on the driving shafts of the two driving members.

[0016] In a feasible implementation manner, both first brackets are provided with limiting grooves in the same extension direction as the first brackets, and both second brackets are provided with limiting rods slidably connected to the corresponding limiting grooves.

[0053] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the description of the present invention, it should be noted that the orientations or positional relationships indicated by the terms "left side", "right side", "upper side", "lower side", "above", "below", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0054] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0055] In addition, in the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0056] A non-powered tobacco hemp removal device, see Figure 1, including a mounting base 1, a lifting mechanism 2 arranged in the mounting base 1 and a hemp thread removing mechanism 3 connected to the driving end of the lifting mechanism 2; the hemp thread removing mechanism 3 includes a first truss 31 connected to the driving end of the lifting mechanism 2 and two first brackets 32 symmetrically arranged at both ends of the first truss 31 and extending downward, and a hemp thread removing roller 33 is provided between the two first brackets 32. As an illustration, the utility model is installed above the vibrating conveyor when in use, and the hemp thread removing roller 33 is located above the vibrating conveyor belt. When tobacco is transported on the vibrating conveyor, the hemp rope, hemp thread and other hemp threads in the tobacco usually float on the upper surface of the tobacco. Therefore, when the hemp threads touch the hemp thread removing roller 33, they will push the hemp thread removing roller 33 to rotate, and at the same time, the hemp thread removing roller 33 will adhere to the hemp threads, thereby removing the hemp threads in the tobacco. In addition, the unpowered state described in the present invention means that the hemp removing roller 33 does not require an additional driving mechanism, and the hemp removing roller 33 can be driven to rotate only by the hemp in the tobacco. Once the hemp removing roller 33 starts to rotate, the hemp can be adhered to more evenly, further improving the hemp removing effect of the hemp removing roller 33.

[0057] In the non-powered tobacco hemp removing device provided by the embodiment of the present utility model, refer to Figure 1 The mounting base 1 includes a mounting frame 11 and a second truss 12 arranged below the mounting frame 11, and two symmetrical second brackets 13 extending downward are provided at both ends of the second truss 12; the first truss 31 is arranged between the two second brackets 13.

[0058] In the non-powered tobacco hemp removing device provided by the embodiment of the present utility model, refer to Figure 1 and Figure 2 The bottoms of the two first brackets 32 are each provided with an adapter frame 34. Each adapter frame 34 is provided with multiple groups of slots 35 arranged in sequence along the tobacco conveying direction. The ends of the de-hemp roller 33 are respectively located in the slots 35 of the two adapter frames 34. For illustration, the tobacco conveying direction is the conveying direction of the vibrating conveyor. When there is too much hemp adhering to the de-hemp roller 33, the de-hemp roller 33 can be directly lifted upward to disengage the ends of the de-hemp roller 33 from the slots 35 of the two adapter frames 34, thereby removing the de-hemp roller 33. When installing the de-hemp roller 33, the ends of the de-hemp roller 33 are usually installed in the corresponding slots 35 of the two adapter frames 34, that is, the de-hemp roller 33 and the vibrating conveyor belt remain parallel. Of course, in special circumstances, the ends of the de-hemp roller 33 can also be installed in non-corresponding slots 35, so that an angle is formed between the de-hemp roller 33 and the vibrating conveyor belt. Therefore, the installation of the hemp removing roller 33 should be flexible to facilitate the operator to disassemble and assemble the hemp removing roller 33 or adjust the relative position of the hemp removing roller 33.

[0059] In the non-powered tobacco hemp removing device provided by the embodiment of the present utility model, refer to Figures 1 to 3 , further comprising two adapter assemblies 4, one mounted at each end of the de-hemp roller 33; the adapter assembly 4 comprises a connecting shaft 41 disposed within a slot 35 and an inner shaft 42 connected to one end of the connecting shaft 41; both ends of the de-hemp roller 33 are provided with inner shaft 42 openings 33.1 extending into the interior of the de-hemp roller 33 and rotatably connected to the corresponding inner shaft 42. For illustration, the shape of the connecting shaft 41 should match that of the slot 35, typically being rectangular; the shape of the inner shaft 42 should match that of the inner shaft 42 openings 33.1, typically being cylindrical. During use, the connecting shaft 41 and the inner shaft 42 do not rotate. They only serve to limit and relatively fix the hemp removing roller 33. Since the opening 33.1 of the inner shaft 42 in the hemp removing roller 33 matches the inner shaft 42, when the hemp fibers come into contact with the hemp removing roller 33, they push the hemp removing roller 33 to rotate around the inner shaft 42. As a supplementary explanation, a bearing is also provided between the inner shaft 42 and the opening 33.1 of the inner shaft 42.

[0060] In the non-powered tobacco hemp removing device provided by the embodiment of the present utility model, refer to Figure 2 and Figure 3 The hemp removing roller 33 is provided with a plurality of hemp removing sheets 33.2 evenly spaced and extending in the same direction as the hemp removing roller 33. As an illustration, the hemp removing sheets 33.2 are generally rectangular in shape, and the extending distance of the hemp removing sheets 33.2 is generally consistent with the hemp removing roller 33. The hemp removing sheets 33.2 can expand the range of hemp adhesion of the hemp removing roller 33. In a specific embodiment, refer to Figure 1 Four hemp removing sheets 33.2 are evenly distributed on the hemp removing roller 33, and the shape, size and material of the four hemp removing sheets 33.2 are consistent.

[0061] In the non-powered tobacco hemp removing device provided by the embodiment of the present utility model, refer to Figure 2 , the hemp removing sheet 33.2 is provided with a plurality of hemp sticking balls 33.3. As an explanation, the hemp sticking balls 33.3 can adhere to the hemp in the tobacco, thereby further improving the hemp removal ability of the hemp removing roller 33. As a supplementary explanation, the distribution of the hemp sticking balls 33.3 on the hemp removing sheet 33.2 should not be restricted, and there may usually be no distribution pattern, but the distribution density in each area should be kept consistent as much as possible. As a supplementary explanation, the material of the hemp sticking balls can be polyester or nylon, preferably nylon. The principle of the hemp sticking balls adhering to the hemp is roughly the same as the principle of Velcro adhesion, that is, the hemp is hooked by the hook-shaped structure on the hemp sticking balls.

[0062] In the non-powered tobacco hemp removing device provided by the embodiment of the present utility model, refer to Figure 1 The function of the lifting mechanism 2 is to adjust the height of the gap between the lint removal roller 33 and the belt of the vibrating conveyor. The lifting mechanism 2 includes two driving members 21 symmetrically arranged in the mounting seat 1, a movable rod 22 arranged between and slidably connected to the drive shafts of the two driving members 21, and a plurality of connecting rods 23 arranged below the movable rods 22 and passing through the second truss 12 to connect to the first truss 31. The adjustment method of the lifting mechanism 2 is as follows: the rotation of the driving member 21 drives the movable rod 22 to rise and fall, the rising and falling of the movable rod 22 drives the rising and falling of the first truss 31, and the rising and falling of the first truss 31 drives the rising and falling of the lint removal roller 33. As an example, different types of tobacco usually have different thicknesses. When the thickness of the tobacco is too high, the lint removal roller 33 can easily adhere to the tobacco, resulting in a waste of raw materials. When the thickness of the tobacco is too low, the lint removal roller 33 has difficulty adhering to the lint in the tobacco, thereby reducing the efficiency of lint removal. Therefore, by adjusting the height between the lint removal roller 33 and the vibrating conveyor belt according to the different thicknesses of tobacco, the lint removal roller 33 can be adapted to different thicknesses of tobacco, thereby improving the applicability of the present invention. In a specific embodiment, one of the driving members 21 can be driven by a servo motor and a ball screw, while the other driving member 21 can serve as a driven member and adopt an optical axis and a slider.

[0063] In the non-powered tobacco hemp removing device provided by the embodiment of the present utility model, refer to Figure 1 The lifting mechanism 2 also includes a transmission rod 24, which is synchronously rotatably connected to the drive shafts of the two driving members 21 through gears; a rotating handle 25 is provided at one end of the transmission rod 24, and the operator can rotate the rotating handle 25 to rotate the transmission rod 24. As an explanation, the function of the transmission rod 24 is to synchronize the rotation of the two driving members 21 to ensure that the two driving members 21 can maintain synchronous rotation. Only when the two driving members 21 maintain synchronous rotation can the hemp removing mechanism 3 maintain balance during the lifting process. In a specific embodiment, two first bevel gears 26 are provided on the transmission rod 24, and the drive shafts of the two driving members 21 are provided with second bevel gears 27 that mesh with the corresponding first bevel gears 26. The first bevel gears 26 and the second bevel gears 27 can transmit the rotation of the transmission rod 24 to the drive shafts of the driving members 21, thereby causing the drive shafts of the driving members 21 to rotate synchronously.

[0064] In the non-powered tobacco hemp removing device provided by the embodiment of the present utility model, refer to Figure 1Each of the two first brackets 32 is provided with a limiting slot 32.1 that extends in the same direction as the first bracket 32, and each of the two second brackets 13 is provided with a limiting rod 13.1 that is slidably connected to the corresponding limiting slot 32.1. For illustration, to prevent overextension of the lifting mechanism 2 during the lifting process, the limiting rod 32.1 rises and falls synchronously within the limiting slot 13.1 during the lifting of the first bracket 32. When the limiting rod 32.1 contacts the ends of the limiting slot 13.1, the limiting position is reached.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
