DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0018] Embodiment: A leather measuring machine for measuring leather size, such as Figures 1-4As shown in the figure, it includes a mounting frame 1, a conveying component 2, a motor 3, a measuring device 4 and a display 5. A conveying component 2 is provided on the mounting frame 1. A motor 3 for driving the movement of the conveying component 2 is arranged at the left part of the front side of the mounting frame 1. A measuring device 4 is arranged at the middle side of the top of the mounting frame 1. The measuring device 4 is located directly above the conveying component. A display 5 is arranged at the front side of the measuring device 4. The display 5 is connected to the measuring device 4 through a circuit. Its characteristics are: It also includes a support 6, a lifting frame 7, a turning frame 8, a first roller 10, a compression spring 11 and a downward pull grip 12. The support 6 is arranged at the left side of the top of the mounting frame 1. Guide rods are arranged on both the left and right sides of the top of the lifting frame 7. The lifting frame 7 is slidably connected to the middle cross bar of the support 6 through the guide rods. A flat bar is arranged between the tops of the two guide rods of the lifting frame 7. Compression springs 11 are sleeved on both guide rods. One end of the compression spring 11 abuts against the flat bar, and the other end of the compression spring 11 abuts against the middle cross bar of the support 6. A downward pull grip 12 is arranged on the left side of the lifting frame 7. The lower part of the lifting frame 7 is rotatably connected to a turning frame 8 through a rotating shaft. Two first rollers 10 are rotatably connected to the lower part of the turning frame 8 through a rotating shaft. The two first rollers 10 are arranged side by side in close contact. When the utility model works, the motor 3 installed at the left front corner of the mounting frame 1 is powered on to drive the rotating shaft to rotate. Then the rotating shaft drives the conveying component 2 to convey to the right. When the leather placed on the conveying component 2 is conveyed to below the first roller 10, the staff holds the downward pull grip 12 and pulls it downward. The downward pull grip 12 drives the lifting frame 7 downward. The support 6 is composed of two C-shaped rods and a middle cross bar. The two feet of one C-shaped rod are fixed at the two left corners of the mounting frame 1. The two feet of the other C-shaped rod are fixed at the front and back sides of the upper surface of the middle position of the mounting frame 1. The two ends of the middle cross bar are respectively fixed at the middle positions of the tops of the two C-shaped rods. Due to the double C-shaped rod design of the support 6, the pulling force of the staff pulling the downward pull grip 12 downward and the gravity of devices such as the lifting frame 7, the turning frame 8 and the first roller 10 are evenly distributed to the four feet at the bottom of the support 6. The lifting frame 7 drives the turning frame 8 downward, and finally drives the first roller 10 downward until it contacts the leather. The turning frame 8 is composed of two parts. Both parts are rotatably connected to the lower part of the lifting frame 7 through a rotating shaft. One first roller 10 is rotatably connected to the lower part of each of the two parts of the turning frame 8. The angle between the two parts is an acute angle. So after the two first rollers 10 contact the leather, they will roll in opposite directions by themselves to flatten the leather to the front and back sides. It also includes a straight spring 9. Two straight springs 9 are sleeved on the rotating shaft at the rotating connection between the lifting frame 7 and the turning frame 8. The two straight springs 9 are respectively located on the left and right sides of the rotating shaft and are clamped between the lifting frame 7 and the turning frame 8. The straight spring 9 can prevent the turning frame 8 and the first roller 10 from moving left and right. Then the staff releases the downward pull grip 12. The lifting frame 7 moves upward as a whole under the drive of the compression spring 11 until the lifting frame 7, the turning frame 8, the first roller 10, the compression spring 11 and the downward pull grip 12 return to the initial position and state. It also includes a connecting frame 13, a roller frame 14 and a second roller 15. A connecting frame 13 is fixed on the left side surface of the measuring device 4.A roller frame 14 is provided below the connecting frame 13, and a second roller 15 is provided below the roller frame 14. The second roller 15 is rotatably connected to the roller frame 14. When there is left-right stacking of the leather that has been flattened front and back, the leather is conveyed by the conveying assembly 2 to the position of the second roller 15, flattened left and right by the second roller 15, and then measured under the measuring device 4. The leather size is displayed on the display 5. Subsequently, the leather is conveyed to the right end of the conveying assembly 2. There are also a placement rack 16, a collection box 17 and a handle 18. The placement rack 16 is fixed to the right side of the mounting rack 1. The single placement rack 16 is in an L shape. A collection box 17 is provided above the placement rack 16. Handles 18 are provided on both sides of the collection box 17. Subsequently, the leather slides into the collection box 17 on the placement rack 16. When the collection box 17 is filled with leather, the staff removes the whole box of leather through the handles 18 on both sides of the collection box 17.,

[0019] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
