The cover of a coil book is made of a variety of materials, including plastic, cloth, soft and hard paper, etc. The inner pages are mainly writing paper, which can be used to take notes, or as exercise books and homework books. Its advantage is that it is very convenient to use. A small coil book is like a notepad, which can be carried in a pocket, or a page can be torn off and used at will. At the same time, it does not have the disadvantage of thick notepads that are inconvenient to turn pages. By opening a number of regularly arranged through holes on one side of the notebook page through a punching structure, many notebook pages are connected in series through coils in the through holes.

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] like Figure 1-5As shown, an adjustable notebook page punching structure includes a main body 1, side frames 2 are installed on the inner walls of both sides of the main body 1, a connecting frame 3 is installed on the other end of the side frame 2, a support seat 4 is installed inside the main body 1, a punching component 5 is installed at one end of the main body 1, a movable plate 51 is installed in the punching component 5, a punching column 52 is installed on the outer wall below the movable plate 51, sleeve rods 53 are installed at both ends of the punching column 52, a pressing plate 6 is installed at the lower end of the sleeve rod 53, and a through-wall penetrating hole is provided on the pressing plate 6. Upper through hole 61, an electric telescopic rod 41 is installed just below the movable plate 51, a punching seat 7 is fixedly installed between adjacent electric telescopic rods 41, a lower through hole 71 penetrating the outer wall is opened on the punching seat 7, a collecting bin 72 is installed at the bottom of the punching seat 7, square blocks 8 are installed on both sides of the bottom end of the lower through hole 71, a spring 81 is installed at one end of the square block 8, and a movable block 83 is installed at the other end of the spring 81, a slide groove 82 is installed on the lower outer wall of the punching seat 7, and an arc groove 84 is opened at one end of the movable block 83.

[0027] Combination Figure 1 , Figure 2 As shown, a base 21 is installed at one end of the side frame 2, a guide plate 22 is installed below the base 21, and a support rod 23 is installed between the guide plate 22 and the base 21. The side frame 2 and the base 21 are connected by the support rod 23, the support rod 23 on one side of the side frame 2 passes through the base 21 horizontally, and the support rod 23 on the top of the guide plate 22 passes through the base 21 vertically, and a threaded rod is meshed and installed in the base 21.

[0028] Furthermore, during the notebook punching process, a pulley and a belt are installed to convey the notebook pages to the bottom of the punching component 5, and a guide plate 22 is symmetrically installed in the main body 1. There is a gap between the guide plate 22 and the main body 1 to prevent the pages from falling during the high-speed conveying process; by rotating the threaded rod, the gap between adjacent guide plates 22 can be adjusted, or the height of the guide plate 22 can be adjusted to adapt to the production of notebooks of different sizes.

[0029] Combination Figure 1 , Figure 2 As shown, two connecting blocks 31 are symmetrically installed in the middle of the connecting frame 3, and a support rod 23 is fixedly installed between adjacent connecting blocks 31. A through pin is installed between the connecting frame 3 and the connecting block 31 below. The connecting frame 3 and the connecting block 31 below are rotatably installed, and a connecting block 32 is rotatably installed in the top connecting block 31, and a limit plate 33 is installed through the other end of the connecting block 32.

[0030] Furthermore, due to the high speed of the book page transmission process, the book page may be misaligned when it moves to the punching component 5, resulting in the same hole positions between the punched pages later. Therefore, the position of the book page is adjusted each time the limit plate 33 moves towards each other.

[0031] Combination Figure 2 , Figure 3 As shown, electric telescopic rods 41 are rotatably mounted on both sides of the support seat 4, a connecting rod 42 is mounted on the top of the electric telescopic rod 41, and the connecting rod 42 and the supporting rod 23 between the connecting block 32 are rotatably mounted.

[0032] Furthermore, the electric telescopic rod 41 drives the connecting rod 42 to pull the connecting block 32 to rotate in the connecting frame 3, thereby driving the upper limiting plate 33 to move.

[0033] Combination Figure 4 , Figure 5 As shown, the punching columns 52 are fixedly installed at the same intervals below the movable plate 51, and a spring 81 is installed on the outside of the sleeve rod 53. The distance between the upper through holes 61 is the same as that between the punching columns 52, the inner diameter of the upper through holes 61 is larger than the punching columns 52, and the length of the upper through holes 61 is smaller than that of the punching columns 52.

[0034] Furthermore, the positions of the punching column 52 and the upper through hole 61 and the lower through hole 71 correspond to each other. When punching, the waste chips from the cut parts pass through the upper through hole 61 and the lower through hole 71 and fall into the collection bin 72. At the same time, the spring 81 outside the sleeve rod 53 acts as a buffer to prevent damage to the equipment.

[0035] Combination Figure 4 , Figure 5 As shown, the extended end of the electric telescopic rod 41 passes through both sides of the punching seat 7, the sum of the lengths of the upper through hole 61 and the lower through hole 71 is smaller than the punching column 52, and a door is hinged on one side of the collection bin 72. The slide groove 82 is located between the square block 8 and the lower through hole 71, the movable block 83 is slidably connected to the slide groove 82, and the sharp part of the arc groove 84 is located at the top.

[0036] Furthermore, the waste paper scraps at the punching place are moved to the collecting bin 72 through the upper through hole 61 and the lower through hole 71, close to the bottom of the punching column 52, and contact with the movable blocks 83 on both sides. The internal spring 81 is deformed and compressed. When the punching column 52 moves upward, the spring 81 squeezes the movable block 83 to scrape off the waste paper scraps.

[0037] The working principle of the utility model is:

[0038] During the notebook punching process, by adjusting the position of the guide plate 22 , the book pages moving at high speed are moved to the position of the punching component 5 along the gap between the main body 1 and the guide plate 22 .

[0039] When it moves to the punching component 5, the internal electric telescopic rod 41 pulls the support rod 23 to move inward, so that the bottom connecting block 31 rotates in the connecting frame 3, and the top connecting block 31 pushes the limiting plate 33 to move inward, and the position of the middle book page is adjusted by the relative movement of the limiting plates 33 on both sides to ensure that the position of each punching hole is the same.

[0040] When one side of the book page moves to the top of the punching seat 7, the electric telescopic rod 41 shortens, pulling the movable plate 51 downward. As the interval between the movable plate 51 and the book page shortens, the pressing plate 6 is first pressed on the book page, and the sleeve rods 53 on both sides shorten, and the external spring 81 is deformed and compressed. Then the punching column 52 passes through the upper through hole 61 and presses against the paper inside. The paper at the lower through hole 71 is cut by the interaction force between the punching column 52 and the lower through hole 71, and then continues to move downward to punch the book page. The column 52 passes through the lower through hole 71 and carries the waste paper scraps to the collecting bin 72. When the punching column 52 contacts the movable block 83, the internal spring 81 is deformed and compressed, and the movable block 83 moves to both sides along the slide groove 82. The waste paper scraps of the punching column 52 passing through the arc groove 84 will automatically fall into the collecting bin 72. The waste paper scraps that are close to the bottom of the punching column 52 will be scraped off by the movable block 83 when the punching column 52 moves upward. The bin door can be opened later to clean up the waste paper scraps inside.
