[0025] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a front edge paper stop mechanism of a high-speed water-based ink printer, comprising a base 1, a plurality of cylinders 4 are rotatably connected to the inner wall of the base 1, a DC motor 3 is fixedly connected to the right side of the base 1, an output end of the DC motor 3 passes through the base 1 and is fixedly connected to the front cylinder 4, a conveyor belt 5 is arranged on the outer side of the cylinder 4, side panels 6 are fixedly connected to the left and right sides of the top of the base 1, a top panel 7 is fixedly connected to the top of the side panel 6, a baffle 9 is fixedly connected to the rear side of the top panel 7, a slide groove 8 is provided at the bottom of the top panel 7, a movable block 17 is slidably connected to the left and right sides of the inner wall of the slide groove 8, and a front side of the bottom of the top panel 7 is fixedly connected to the top panel 7.

The left and right sides of the top of the moving plate 15 are rotatably connected with rotating plates 16. The two rotating plates 16 are rotatably connected with the corresponding movable blocks 17 respectively. The bottom of the movable block 17 is fixedly connected with a clamping plate 18. The top front side of the base 1 is fixedly connected with a fixed block 10. A plurality of limiting holes 11 are provided on the front side of the fixed block 10.

[0026] Specifically, by starting the DC motor 3, the cylinder 4 can rotate, and at the same time, the outer conveyor belt 5 can be driven to rotate, so that the cardboard above it moves to the rear side, and at the same time, the baffle plate 9 can block the movement of cardboards except the bottom cardboard. When the bottom cardboard passes through the gap below the baffle plate 9, the cardboard above it will fall under the action of its own gravity, so that the bottom cardboard is moved again, so that the cardboards can pass through in sequence, reducing the possibility of paper jams. When the cardboard is long, by adjusting the height of the T-shaped block 12 on the fixed block 10, the cardboard is tilted at an angle so that its center of gravity is above or behind the T-shaped block 12 to prevent it from falling. The position of the T-shaped block 12 can be fixed by the engagement of the cardboard 13 with the limiting hole 11 to prevent accidental sliding and causing the cardboard to fall.

[0027] Reference Figure 3 and Figure 5 The straightening mechanism 2 includes a plurality of filter holes 201, and the plurality of filter holes 201 are opened on the outer side of the side plate 6. A cleaning brush 202 is fixedly connected to the front end of an adjacent side of the side plate 6, and a rotating column 203 is rotatably connected to the rear end of an adjacent side of the side plate 6.

A rolling cylinder 205 is fixedly connected to the outer wall of the rotating column 203, and a groove block 206 with holes is fixedly connected to the left side of the right side plate 6, and a plurality of fans 207 are fixedly connected to the inner wall of the groove block 206 with holes;

[0028] Specifically, by starting the fan 207, air can be blown to the right side to generate air flow inside the cardboard. At the same time, the dust above the cardboard can be basically cleaned by the cleaning brush 202, and the flying dust will be adsorbed on the filter hole 201 along with the air flow generated by the fan 207, thereby reducing the impact of the dust. Through the meshing connection between the first gear 204 and the second gear 208, the rotating cylinder 4 can drive the first gear 204 and the rotating column 203 and the rolling cylinder 205 above it to rotate, so that the cardboard can be rolled and straightened.

[0029] Reference Figure 2 , Figure 3 and Figure 5 The left and right sides of the top of the T-shaped block 12 are rotatably connected with rollers 19, and a plurality of limit grooves 20 are provided on the front side of the baffle plate 9; a positioning plate 23 is fixedly connected to the rear side of the top plate 7, a detection probe 22 is fixedly connected to the bottom of the positioning plate 23, and a rear cover plate 21 is rotatably connected to the rear side of the positioning plate 23; a support column 24 is rotatably connected to the rear side of the left portion of the right side plate 6, and a clamping hole 25 is provided on the front side of the rear cover plate 21, and the support column 24 is engaged with the clamping hole 25; a fixed column 26 is fixedly connected to the right side of the left clamp plate 18, and an electrostatic absorption ball 27 is fixedly connected to the right end of the fixed column 26;

[0030] Specifically, the roller 19 can facilitate the movement of the bottom cardboard, the limiting groove 20 can block the cardboard above the bottom to reduce the pressure on the bottom cardboard, the detection probe 22 can scan and inspect the cardboard that comes out, and the rear cover 21 can form a closed space with the baffle 9 and the side plate 6. By rotating the support column 24 and engaging it with the card hole 25 above the rear cover 21, the rear cover 21 can be supported to open an angle for easy cleaning and maintenance. The fixing column 26 and the static absorption ball 27 can reduce the occurrence of paper jams caused by static electricity on the cardboard.

[0031] Reference Figure 1 and Figure 4 The left side of the left side panel 6 is fixedly connected with a controller 28, and the controller 28 is electrically connected to the DC motor 3, the electric telescopic rod 14 and the fan 207 respectively; the outer side of the controller 28 is fixedly connected with a housing 29, and the outer side of the housing 29 is rotatably connected with a dust cover 30;

[0032] Specifically, the controller 28 can control the starting and operating power of the DC motor 3, the electric telescopic rod 14 and the fan 207 respectively, the outer shell 29 can prevent the controller 28 from being damaged due to collision, and the dust cover 30 can prevent dust from entering the controller 28 and damaging the electronic components inside it.

[0033] Working principle: When using the device, first, place the cardboard to be processed on the conveyor belt 5. After starting the DC motor 3, the cylinder 4 starts to rotate, and at the same time drives the outer conveyor belt 5 to rotate, so that the cardboard moves to the rear side. In the cardboard transmission process, the baffle 9 plays a key role. The baffle 9 can cleverly block the movement of cardboards except the bottom cardboard. When the bottom cardboard passes through the gap under the baffle 9, the cardboard above it will fall under the action of its own gravity, thereby moving the bottom cardboard again. This ensures that the cardboard can pass through the transmission system in turn, greatly reducing the possibility of paper jams. In addition, in order to solve the transmission problem of longer cardboard, by adjusting the height of the T-block 12 on the fixed block 10, the cardboard can be tilted at an angle so that its center of gravity is located above or behind the T-block. This effectively prevents the cardboard from falling during the transmission process and ensures the continuity and stability of production. In order to ensure the stable position of the T-block 12 and prevent accidental sliding from causing When the cardboard falls, the position of the T-shaped block 12 can be fixed by the engagement of the cardboard block 13 with the limiting hole 11, so that it remains stable after adjustment, providing a strong guarantee for the stable transmission of the cardboard, and an airflow can be generated by starting the fan 207. This airflow is blown out from the right side of the mechanism, which not only generates air flow inside the device, but also helps to blow up the dust and debris on the cardboard. At the same time, the cardboard can be effectively cleaned of dust above it through the cleaning brush 202. The blown dust will not float around, but will be adsorbed on the filter hole 201 of the side plate 6 with the air flow generated by the fan 207. In addition, the rotating cylinder 4 can be connected to the meshing of the second gear 208 and the first gear 204, driving the rotating column 203 and the rolling cylinder 205 to rotate, thereby realizing the rolling and straightening of the cardboard. After such treatment, the cardboard not only becomes flatter, but the dust on it is also thoroughly removed, which greatly improves the quality of the cardboard and the efficiency of subsequent processing.
