[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0034] See also Figure 1-Figure 6 .
[0035] In view of the problems mentioned in the above background technology, the embodiment of the utility model provides a tobacco leaf cutting device to solve the above technical problems, and its technical solution is as follows:
[0036] A tobacco leaf cutting device, comprising: a base 110, a hinge seat 112, two loading platforms 120 and a cutter 140;
[0037] Two loading platforms 120 are fixed on the base 110 at intervals; specifically, the loading platforms 120 are plate structures, and their bottoms are fixed on the base 110 through columns 111;
[0038] The cutting table 130 is fixed on the base 110 and is located between the two loading tables 120;
[0039] The articulated seat 112 is fixed on the base 110 and is located on the same side of the two loading platforms 120; specifically, the center position of the articulated seat 112 is aligned with the middle position between the two loading platforms 120;
[0040] The cutter 140 is located between the two loading platforms 120, and one end of the cutter 140 is hinged on the hinge seat 112;
[0041] The cutting portion 142 of the cutting knife 140 is provided with a vertically penetrating long knife hole 142 a ; when the cutting knife 140 is rotated and pressed downward, the long knife hole 142 a can pass through the cutting table 130 .
[0042] It should be noted that the transverse cross-sectional value of the long knife hole 142 a is greater than the transverse cross-sectional value of the cutting table 130 . In this design, when the cutter 140 is rotated and pressed down, the long knife hole 142 a on the cutter 140 can smoothly pass through the cutting table 130 .
[0043] The working method of a tobacco leaf cutting device provided by the embodiment of the utility model is as follows:
[0044] 1. When cutting tobacco leaves into strips, the experimenter places tobacco leaves of different batches on two loading platforms 120 in batches, and manually adjusts the positions of the tobacco leaves on the loading platforms 120 to ensure that tobacco leaves of different batches are cut at the same position;
[0045] 2. After the tobacco leaves have adjusted their position, the experimenter rotates and presses down the cutter 140 to make the long knife hole 142a pass through the cutting table 130. The tobacco strips cut and left on the cutting table 130 are the tobacco leaf tensile test sample strips required for the experiment; the size of the tobacco leaf tensile test sample strips is generally 1.5cm*24cm.
[0046] It should be noted that in order to prevent the position of the tobacco leaf from being offset during the rotation and pressing of the cutter 140, a tobacco leaf positioning mechanism is provided on the tobacco leaf cutting device. The specific structure of the tobacco leaf positioning mechanism is as follows:
[0047] The tobacco leaf positioning mechanism includes a guide post 220, a spring 230, a blocking piece 240 and a positioning assembly 250;
[0048] The guide post 220 is fixed on the base 110 and is located at the rear side of the hinge seat 112;
[0049] The positioning assembly 250 includes a pressing plate 251, a vertical short rod 252 and a long rod 253;
[0050] The long rod 253 is arranged obliquely, and a vertical hole 253a is arranged at one end of the long rod 253. The vertical hole 253a passes through the guide column 220 to connect the long rod 253 to the guide column 220; the other end of the long rod 253 is hinged to the vertical short rod 252;
[0051] The diameter of the vertical hole 253a is larger than the diameter of the guide column 220, so as to provide a certain avoidance space for the long rod 253 when it moves up and down.
[0052] The pressing plate 251 is located below the long knife hole 142a, and its top is hinged to the bottom of the vertical short rod 252; specifically, the pressing plate 251 is made of metal, which increases the gravity of the pressing plate 251 and facilitates the pressing plate 251 to position the tobacco leaves by its own gravity;
[0053] The baffle 240 is fixed to the top of the guide column 220 , the spring 230 is sleeved on the guide column 220 and is located between the long rod 253 and the baffle 240 , and the upper end of the spring 230 is fixedly connected to the baffle 240 , and the lower end of the spring 230 is fixedly connected to the end of the long rod 253 .
[0054] It should be noted that the setting of the spring 230 here keeps the long rod 253 in an inclined state and gives the pressure plate 251 a pre-tightening force to prevent it from moving up and tilting, thereby improving the tobacco leaf positioning effect. When the spring 230 is in a natural state connected to the long rod 253, the pressure plate 251 is maintained in a horizontal drooping state.
[0055] After cutting the tobacco leaves into strips and adjusting the position of the tobacco leaves, the pressing plate 251 is positioned and pressed against the tobacco leaves under the action of its own gravity and with the help of the vertical short rod 252, the long rod 253 and the spring 230. The experimenter rotates and presses the cutter 140 to directly cut the tobacco leaves into strips.
[0056] In this embodiment, for the end portion where the long rod 253 is hinged to the vertical short rod 252, the maximum width of this end portion is greater than the hole width of the long knife hole 142a.
[0057] The maximum width of this end is designed to be larger than the hole width of the long knife hole 142a. When the experimenter rotates and lifts the cutter 140 upward, the long rod 253 and the pressing plate 251 will also be lifted up by limiting the position because the maximum width of the end where the long rod 253 and the vertical short rod 252 are hinged is larger than the hole width of the long knife hole 142a. At this time, it is convenient for the experimenter to place tobacco leaves under the pressing plate 251.
[0058] In this embodiment, the tobacco positioning mechanism also includes a shell 210, which is buckled on the guide column 220, the spring 230, and the baffle 240, and a slot for the long rod 253 to pass through is provided on the side of the shell 210 facing the hinge seat 112; the shell 210 is provided to cover related structural components and improve the aesthetics of the device.
[0059] In this embodiment, the cutting table 130 is a rectangular structure, and the long knife hole 142a is a rectangular structure; the width of the cutting table 130 is equal to the hole width of the long knife hole 142a; this structural setting can improve the uniformity of tobacco strip cutting and the regularity of the tobacco strip edge when the cutter 140 is rotated and pressed down to cut tobacco leaves into strips.
[0060] In this embodiment, the bottom blade portion 142b of the cutter 140 is in a convex arc shape, which facilitates the cutting operation.
[0061] In this embodiment, a handle 141 is provided at the free end of the cutter 140 for easy gripping.
[0062] A tobacco leaf cutting device provided in an embodiment of the utility model has the following beneficial effects: the utility model designs a tobacco leaf cutting device, which can facilitate experimenters to flexibly sample different tobacco leaves at a uniform position and obtain tobacco leaf tensile test sample strips of uniform specifications, which is simple and convenient.

Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment.
