Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco production technology, and in particular to a raw tobacco frame with a cleaning function. Background Technology
[0002] Raw tobacco refers to naturally air-dried tobacco leaves that have not undergone any processing or conditioning. During the threshing and re-drying process, after the raw tobacco is sorted and packed into frames, it is often left to stand for a period of time until the batch reaches a certain scale or all modules and grades have been sorted before it is fed into the grid. The traditional framing method for raw tobacco is generally based on the actual production needs and tobacco grade of each re-drying plant. The weight of tobacco leaves in each frame is between 350kg and 450kg. The long-term storage and compression of the tobacco leaves often results in a certain amount of tobacco leaves or fragments accumulating at the bottom of the frame. This is especially true for higher-grade tobacco leaves, which have a higher oil content, and long-term compression makes the tobacco leaves stick even more firmly to the bottom of the frame. When feeding, even if the frame is completely inverted 180 degrees, the stuck tobacco leaves and fragments are still difficult to completely detach from the bottom of the frame.
[0003] In response to the above situation, manual cleaning is often required, which wastes a lot of manpower and the cleaning effect is poor. At the same time, cleaning during the feeding process requires workers to stand at a high place and lean under the frame, which poses a safety hazard.
[0004] Therefore, it is urgent to study a type of original tobacco rack with a cleaning function to solve the above problems. Utility Model Content

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0035] like Figures 1 to 4As shown, this embodiment provides a raw tobacco frame with a cleaning function. The raw tobacco frame with a cleaning function includes a frame 100 and a cleaning component 200. The frame 100 includes a frame bottom 110 and a fence 120 surrounding the frame bottom 110. The cleaning component 200 includes a cleaning element 210, which is movably constrained to the frame 100 along the length direction. Along the length direction, at least one side of the cleaning element 210 has a cleaning shovel 211. The cleaning shovel 211 and the frame bottom 110 are arranged at an angle. The cleaning element 210 is arranged so that it can separate the raw tobacco adhering to the frame bottom 110 from the frame bottom 110 during movement along the length direction.
[0036] During use, the cleaning shovel 211 on the cleaning component 210 can scoop up the raw tobacco adhering to the bottom of the frame 110 during the movement of the cleaning component 210. The scooped-up raw tobacco falls off under the action of gravity, thereby avoiding the waste of a lot of manpower and effectively improving the cleaning effect. At the same time, cleaning is carried out during the feeding process, and the staff only needs to be on the side of the frame 100, reducing safety hazards.
[0037] In some embodiments, the cleaning member 210 extends along its width, has a triangular prism cross-section, and has an abutment surface and two cleaning surfaces circumferentially. The abutment surface contacts or has a gap with the frame bottom 110, and the cleaning surfaces form a cleaning shovel portion 211. This arrangement allows the cleaning member 210 to complete one cleaning cycle by moving in only one direction, greatly improving cleaning efficiency.
[0038] To facilitate shoveling up the raw tobacco, in some embodiments, the included angle between the two cleaning surfaces is an obtuse angle. Furthermore, the angles between the two cleaning surfaces and the frame bottom 110 are also obtuse angles. This arrangement allows the cleaning surfaces to easily enter the gap between the raw tobacco and the frame bottom 110, thereby shoveling up the raw tobacco.
[0039] Regarding the connection method between the cleaning component 210 and the frame 100, in some embodiments, the frame bottom 110 is provided with two limiting grooves 130 spaced apart along the width direction. Both limiting grooves 130 extend in the length direction, and their openings are opposite to each other. The cleaning component 200 includes connecting rods 220 at both ends of the cleaning component 210 and limiting members 230 connected to the corresponding connecting rods 220. The connecting rods 220 pass through the openings of the corresponding limiting grooves 130, and the limiting members 230 are located within the corresponding limiting grooves 130. The outer diameter of the limiting member 230 is larger than the opening width of the limiting groove 130, and the outer diameter of the connecting rods 220 is smaller than the opening width of the limiting groove 130. The limiting groove 130 is a T-shaped groove. The length direction is the front-to-back direction, and the width direction is the left-to-right direction.
[0040] In some embodiments, the limiting member 230 is a rotating wheel, which is rotatably connected to the connecting rod 220 via a bearing 240 and can roll into contact with the upper sidewall 131 or lower sidewall 132 of the limiting groove 130. This arrangement makes the movement of the cleaning member 210 smoother, with less resistance, and easier to operate.
[0041] The limiting groove 130 includes a vertical portion and a horizontal portion that are connected. Two strip-shaped fixing members 133 are spaced apart along the height direction. The fixing members 133 extend along the length direction and are formed by bending a sheet-like fixing plate. The two sides of the fixing plate are bent upwards to form side walls 1332, and a bottom wall 1331 is formed between the two side walls 1332. The upper ends of the side walls 1332 are bent inwards to form a top wall 1333, and an entrance is formed between the two top walls 1333. The bottom wall 1331, the two side walls 1332, and the two top walls 1333 form a cavity. The entrances of the two fixing members 133 are positioned opposite each other. The horizontal portion of the limiting groove 130, i.e., the opening of the limiting groove 130, is formed between the top walls 1333 of the two fixing members 133. The portion between the entrances of the two fixing members 133 and the corresponding bottom wall 1331 forms the vertical portion of the limiting groove 130. The connecting rod 220 is located between the two top walls 1333. A portion of the rotating wheel enters the cavity from the inlet of the upper fixing member 133, and a portion of the rotating wheel enters the cavity from the inlet of the lower fixing member 133.
[0042] In some embodiments, the raw tobacco frame with cleaning function further includes a stop assembly 300, which is disposed at the end of the frame bottom 110 along the length direction. The output end of the stop assembly 300 can move between a stop position and a clearance position. When the output end of the stop assembly 300 is in the stop position, it is located on the movement path of the cleaning component 210; when the output end of the stop assembly 300 is in the clearance position, it is located outside the movement path of the cleaning component 210. This arrangement allows the cleaning component 210 to be held in a fixed position, thereby facilitating the determination of the position of the cleaning component 210 and improving operational efficiency.
[0043] Specifically, the stop assembly 300 includes a stop base 310 and a stop member 320. The stop base 310 is located at the bottom of the frame 110, and the stop member 320 is hinged to the stop base 310 and can swing between a stop position and a clearance position. This configuration is simple to operate and helps to improve cleaning efficiency.
[0044] In use, the cleaning component 210 can be fixed to either end of the frame bottom 110, thus facilitating subsequent reuse. In some embodiments, the stop component 300 is provided with at least two sets, one set being provided at one end of the frame bottom 110 and the other set being provided at the other end of the frame bottom 110.
[0045] To prevent the stop 320 from automatically rotating to the avoidance position, in some embodiments, a damping element is provided between the stop 320 and the stop base 310. The damping element can be a rubber pad, with a pin passing through the stop 320, the stop base 310, and the rubber pad, and the rubber pad being sandwiched between the stop 320 and the stop base 310.
[0046] In some embodiments, the cleaning component 210 is provided with a connecting portion (not shown in the figure), which is arranged to be hooked by a hook and to drag the cleaning component 210 along its length. The connecting portion may be a connecting hole.
[0047] Regarding the driving of the cleaning component 210, a servo motor can be installed at one end of the frame 100 along its length. The output end of the servo motor is equipped with a drive wheel, and the other end of the frame 100 along its length is equipped with a driven wheel. A transmission belt is wound between the drive wheel and the driven wheel and is fixedly connected to the cleaning component 210. The forward and reverse rotation of the servo motor can drive the cleaning component 210 to reciprocate along its length.
[0048] To improve the cleaning effect, in some embodiments, the cleaning component 200 further includes a vibrating element disposed on the cleaning component 210 to vibrate the cleaning component 210 and improve the cleaning effect of the raw smoke. The cleaning component 200 also includes a blowing element disposed on the frame 100 to blow away the raw smoke so that the raw smoke falls into the feeding device. In some embodiments, the blowing element disposed on the frame 100 is used to blow away dust; before use, the dust can be blown away by the blowing element to make the frame 100 cleaner.
[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
