[0002] Cotton is an important economic crop and a renewable natural fiber. It possesses excellent properties unmatched by chemical fibers, such as permeability, warmth retention, durability, wear resistance, washability, and high-temperature ironing capabilities. Cotton leaves are a key organ of cotton, and changes in leaf morphology can reflect the cotton's growing environment, its own growth state, and physiological changes. The veins on the leaves are densely covered, and different cotton species may have unique morphologies. Existing measurement devices have difficulty accurately measuring the thickness of leaves at different locations. Most existing measurement devices are limited to a single measurement function and lack a device to effectively secure the leaves during the measurement process. This deficiency can easily lead to deviations in the measurement results and affect the accuracy of leaf thickness measurements. Therefore, it is urgent and important to develop a cotton leaf thickness measurement device designed specifically for cotton leaves that integrates multiple precise measurements and effective fixation.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0023] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a placement plate 1 and a positioning frame 2, and the positioning frame 2 is fixed on both the left and right sides of the upper part of the placement plate 1 by bolts;

[0024] It also contains:

[0025] The connecting frame 3 is divided into two parts and is respectively rotatably arranged on the upper part of the two positioning frames 2 through hinges. A slide groove 4 is provided on the opposite side walls of the two connecting frames 3. A slider 5 is slidably arranged in the slide groove 4. A movable frame 6 is connected between the two sliders 5. A blade positioning mechanism 7 is provided on the connecting frame 3. Electric push rods 18 are rotatably connected to the left and right side walls of the placement plate 1, and one end of the electric push rod 18 is rotatably connected to the connecting frame 3. By controlling the extension and shortening of the electric push rod 18, the automatic flipping of the connecting frame 3 can be achieved, thereby improving the convenience of use.

[0026] A movable block 8 is movably arranged in a movable groove provided on the movable frame 6. A fixed shell 9 is fixed to the upper portion of the movable block 8 by bolts. A lifting plate 10 is movably provided in the fixed shell 9. An infrared ranging sensor 11 is provided in the groove provided in the upper portion of the movable block 8.

[0027] The lifting rod 12 is movably provided in the movable block 8 and the fixed shell 9. Several guide blocks 16 are distributed on the rounded corners of the ring side wall of the lifting rod 12. The lower part of the guide block 16 is fixedly connected to the lifting plate 10, and the guide block 16 is movably provided in the fixed shell 9. The guide block 16 can not only provide guidance for the up and down movement of the lifting rod 12, but also limit the lifting rod 12 to prevent the lifting rod 12 from rotating. The lifting plate 10 is fixedly sleeved on the lifting rod 12. The lower end of the lifting rod 12 is movably provided with a ball 14. The upper part of the connecting frame 3 on the left is fixed with a digital display screen 13 electrically connected to the infrared ranging sensor 11 by bolts;

[0028] The blade positioning mechanism 7 comprises:

[0029] Positioning press frame 7-1, there are two positioning press frames 7-1, which are respectively arranged on the front and rear sides between the two connecting frames 3. The side walls of the connecting frame 3 are provided with movable grooves 15 at the front and rear sides of the slide groove 4. The left and right sides of the positioning press frame 7-1 are fixed with movable blocks 7-2 by bolts, and the movable blocks 7-2 are movably arranged in the movable grooves 15. The lower part of the positioning press frame 7-1 is fixed with an anti-slip pad 17. When the positioning press frame 7-1 is pressed on the blade, the anti-slip pad 17 can generate a large friction force with the blade surface, thereby fully avoiding the position deviation of the blade during the thickness measurement process;

[0030] There are four vertical rods 7-3, which are fixed in four movable grooves 15 by bolts respectively. The movable block 7-2 is movably sleeved on the vertical rod 7-3. The movable sleeve on the vertical rod 7-3 is provided with a spring 7-4. The upper and lower ends of the spring 7-4 are respectively connected to the inner top wall of the movable groove 15 and the movable block 7-2.

[0031] When using the present invention, the electric push rod 18 is controlled to extend, the connecting frame 3 is flipped upward, and the blade is placed on the placement plate 1, and the electric push rod 18 is shortened to flip the connecting frame 3 downward to a horizontal state. At this time, under the action of the downward rebound thrust applied by the spring 7-4 to the moving block 7-2, the positioning pressure frame 7-1 can be pressed on the blade to achieve the fixation of the blade on the placement plate 1. At the same time, the ball 14 will also contact the blade. Affected by the thickness of the blade and the cooperation of the lifting rod 12, a gap equal to the thickness of the blade is generated between the lifting plate 10 and the infrared ranging sensor 11. At this time, the infrared ranging sensor 11 can measure the distance between it and the lifting plate 10, and the measurement data is displayed on the digital display 13, thereby realizing the measurement of the thickness of the contact position between the blade and the ball 14. Then, the horizontal position of the lifting rod 12 and the ball 14 can be adjusted by the movement of the slider 5 in the slide groove 4 and the movement of the movable block 8 in the movable groove, thereby realizing the measurement of the thickness of other positions of the blade.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. Through the cooperation of the connecting frame 3, the slider 5, the movable frame 6, the movable block 8, the fixed shell 9, the lifting plate 10, the infrared distance sensor 11, the lifting rod 12 and the ball 14, the thickness of each position of the cotton leaf can be detected according to the needs;

[0034] 2. The blade positioning mechanism 7 can be used to fix the blade placed on the placement plate 1 to prevent the blade from being offset during the measurement process, thereby affecting the measurement accuracy of the blade thickness.

[0035] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
