Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, specifically to a structure for removing the fibrous tissue from fresh tobacco leaves suitable for belt conveyors. Background Technology

[0002] After the fresh tobacco leaves are harvested at maturity, tobacco farmers need to scrape off the main veins of the tobacco leaves using sugarcane knives and peeling knives before piling them up, cutting them into shreds, and sun-drying them. Existing automated equipment mostly uses a separate deveining knife set above the conveyor belt to cut the main veins of the tobacco leaves, such as the Chinese utility model patent "Deveining Tobacco Slicing Machine" (publication number CN209403555U). There is no technical solution to set the deveining knife inside the conveyor belt. Setting the deveining knife above occupies the upper space, resulting in simple pressure rollers being mainly set above the conveyor belt, making it impossible to set up other devices. Furthermore, how to align the tobacco leaves with the knife as they move on the conveyor belt is a problem encountered in use. Therefore, how to set the deveining knife inside the conveyor belt is a direction for the improvement of this technology. Utility Model Content

[0003] This utility model provides a structure for deveining fresh tobacco leaves suitable for belt conveyors. The deveining knife is set inside the conveyor belt, so that it no longer occupies the upper space of the conveyor belt, and it also has the function of guiding tobacco leaves.

[0004] The specific technical solution of this utility model is: a fresh tobacco leaf deveining structure suitable for belt conveyors, including segmented positioning rollers. Segmented positioning rollers are installed at the front and rear ends of the frame respectively. A positioning boss is provided in the middle of the segmented positioning roller. A main rib guide groove, an elastic support plate, and a special-shaped blade are sequentially arranged on the frame opposite to the positioning boss. The special-shaped blade is provided with a V-shaped cutting edge. The opening direction of the V-shaped cutting edge faces the elastic support plate. The special-shaped blade includes a left blade and a right blade. The left blade and the right blade are installed on the frame through a blade holder seat.

[0005] Furthermore, preferably, the positioning boss of the segmented positioning roller is fitted with a left conveyor belt and a right conveyor belt on both sides respectively.

[0006] Furthermore, preferably, the cross-section of the main rib guide groove is semi-circular or arc-shaped, with its concave surface facing upwards.

[0007] Furthermore, preferably, the main rib guide groove has a large opening at the end away from the elastic support piece, and the main rib guide groove has a small opening at the end near the elastic support piece.

[0008] Furthermore, preferably, the elastic support piece is provided with an acute-angled head near the end of the V-shaped blade, which cooperates with the V-shaped blade.

[0009] Furthermore, preferably, the irregularly shaped blade is slightly higher than the belt surface of the left and right conveyor belts.

[0010] Furthermore, preferably, a platform is provided below the left and right conveyor belts on both sides of the elastic support sheet.

[0011] The beneficial effects of this utility model are: by setting a positioning boss in the middle of the segmented positioning roller, the belt roller can fit two belts, forming a gap on the center line. The rib removal device can be installed in the gap, which no longer occupies the space above the conveyor belt. In addition, a tubular main rib guide groove is provided to guide the main rib of the tobacco leaf to move along the groove guide and accurately enter the elastic support plate and the special blade to precisely remove the main vein tobacco stem.

Detailed Implementation

[0019] In order to make the technical problems and technical solutions solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 3 As shown, a fresh tobacco leaf deveining structure suitable for belt conveyors includes a frame-type belt conveyor frame 1, which is an existing design structure, mostly using a frame structure. Belt rollers are installed at both ends of the frame 101. In this utility model, a segmented positioning roller 101 design is adopted, that is, a positioning boss 102 is set in the middle of the original belt roller. The positioning boss 102 divides the belt roller into left and right sections, so that the left conveyor belt 2 and the right conveyor belt 3 can be respectively fitted on both sides of the positioning boss 102 of the segmented positioning roller 101.

[0023] A motor is installed on the frame 101. The motor drives the pulley of the tail section positioning roller 101 to rotate through the transmission belt, thereby driving the tail section positioning roller 101 to rotate, which in turn causes the left conveyor belt 2 and the right conveyor belt 3 to move synchronously. The left conveyor belt 2 and the right conveyor belt 3 will form a gap 5 along the center line.

[0024] On the frame 1, directly opposite the positioning boss 102, there are main rib guide grooves 6, elastic support plates 7 and irregular blades 8 arranged in sequence.

[0025] like Figure 5 As shown, the cross-section of the main reinforcement guide groove 6 is semi-circular or arc-shaped, with its concave surface facing upwards.

[0026] The main rib guide groove 6 has a large opening 601 at the end furthest from the elastic support plate 7, and a small opening 602 at the section of the main rib guide groove 6 closest to the elastic support plate 7. These openings guide the main ribs of the tobacco leaf along the grooves, ensuring accurate entry onto the elastic support plate 7. The upper surface of the elastic support plate 7 is a pressing surface 701. The shaped blade 8 is slightly higher than the belt surface, while the pressing surface 701 is slightly higher than the shaped blade 8. Figure 4 As shown.

[0027] like Figure 6 As shown, the irregular blade 8 includes a left blade 802 and a right blade 803. The left blade 802 and the right blade 803 are mounted on the frame 1 through a blade holder 804. The inclined blade edges of the left blade 802 and the right blade 803 are aligned to form a V-shaped blade edge 801. An elastic support plate 7 is provided with an acute-angled head 702 near the end of the V-shaped blade edge 801 to cooperate with the V-shaped blade edge 801.

[0028] like Figure 1 As shown, a platform 4 is provided below the left conveyor belt 2 and the right conveyor belt 3 on both sides of the elastic support plate 7.

[0029] The present invention has been described in detail above through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
