Description

Technical Field

[0001] The utility model relates to a paper pressing device for a cross cutter. Background Art

[0002] When processing corrugated cardboard, it is necessary to cut the cardboard to meet the designed size. After the cardboard is cut into the corresponding size by a cutter, since the conveyor belt is in a high-speed motion state at this time, the cut cardboard is light in weight and is prone to floating during the conveying process, resulting in displacement of the cardboard during conveying, which affects the subsequent processing of the cross cutter.

[0003] Therefore, we have designed a paper pressing device for a cross cutter that can be used in conjunction with a cross cutter to press the cardboard output at high speed and prevent the cardboard from flying up. Content of the Utility Model

[0023] As Figure 1 shown, a paper pressing device of a cross-cutting machine includes a support body 2 installed above the conveyor belt 1 of the cross-cutting machine. A pressing plate structure 3 is rotatably arranged inside the support body 2. An adjusting device 4 for adjusting the downward pressure of the pressing plate structure 3 is installed at the top of the support body 2. An infrared counter 5 is also arranged inside the support body 2.

[0024] In the above technical solution, the infrared counter 5 is used to count the number of cardboard sheets, and the adjusting device 4 is used to adjust the downward pressure of the pressing plate structure 3 to ensure that the cardboard can smoothly lift the pressing plate structure 3 when passing through.

[0025] Referring to Figure 2 and Figure 3 shown, the pressing plate structure 3 includes a pressing plate 31. An ear plate 32 is arranged at the bottom position of one end of the pressing plate 31. A support shaft 33 is cooperated with the ear plate 32. A bearing 34 is arranged between the ear plate 32 and the support shaft 33. The support shaft 33 is fixedly connected with the support body 2. A notch 35 is arranged at the other end of the pressing plate 31. A pressing roller 36 is arranged at the notch 35. A rotating shaft (not shown) is arranged at the axis center of the pressing roller 36. The rotating shaft is rotatably connected with the pressing roller 36 and fixedly connected with the notch. The adjusting device 4 cooperates with the pressing plate 31.

[0026] In the above technical solution, when the cardboard is conveyed by the conveyor belt and passes through the pressing plate 31, it is pressed by the pressing roller 36 to ensure that the cardboard fits the conveyor belt and avoid the situation where the cardboard flies up due to the high-speed operation of the conveyor belt.

[0027] Refer to Figure 2 and Figure 3 As shown, the adjusting device 4 includes an adjusting plate 41 installed inside the support body 2, and a servo motor 42 installed on the top of the support body 2. The servo motor 42 is connected to a controller 43. The upper end of the adjusting plate 41 is provided with a threaded tube 44 which has internal threads. The output end of the servo motor 42 is installed with a screw rod 45 that cooperates with the threaded tube. A guide rod 46 is provided at the upper end of the adjusting plate 41, and a linear bearing 47 passing through the guide rod 46 is provided at the top of the support body 2. A spring 48 is fixed to the bottom of the adjusting plate 41, and the lower end of the spring 48 is fixedly connected to the pressing plate 31. The infrared counter 5 is connected to the controller 43.

[0028] In the above technical solution, by rotating the screw rod 45, the height of the adjusting plate 41 is adjusted, so that under the pulling action of the spring 48, a distance is maintained between the pressing roller 36 installed at the end of the pressing plate 31 and the conveyor belt. This distance is smaller than the thickness of the conveyed cardboard, so that the cardboard needs to lift the pressing roller 36 when passing through, thereby playing a pressing role on the cardboard. After the cardboard passes through, the pressing plate 31 returns to its original position.

[0029] According to the elasticity of the spring, through the fine adjustment of the servo motor, the pressing roller 36 is maintained at an appropriate height.

[0030] Refer to Figure 2 and Figure 4 As shown, a high-speed air blower 6 is provided on the outside of the support body 2. The high-speed air blower 6 is connected to an air duct 7. The air duct 7 penetrates into the support body 2 and is located above the infrared counter and below the pressing plate 31. The high-speed air blower 6 is connected to the controller. An air outlet nozzle 8 is inclined at the bottom of the air duct 7, and the air outlet nozzle 8 is inclined towards the conveying direction of the conveyor belt 1.

[0031] The inclination angle of the air outlet nozzle 8 with respect to the conveyor belt is 30°.

[0032] In the above technical solution, the distance between the air outlet nozzle 8 and the pressing roller 36 needs to be smaller than the length of the conveyed cardboard. The high-speed air flow blown out by the air outlet nozzle 8 can make the cardboard better fit the conveyor belt, and under the suppression of this air flow, until the pressing roller 36 acts on the cardboard. After the pressing roller 36 acts on the cardboard, as the cardboard continues to be conveyed, the high-speed air flow blows between the cardboard and the conveyor belt and will not cause the cardboard to be blown up.

[0033] The above technical solution also provides another operation method, which is as follows:

[0034] First, the pressing plate 31 is lifted by the servo motor so that the height of the end of the pressing roller 36 from the conveyor belt 1 is greater than the thickness of the cardboard to be conveyed. At this time, the high-speed blower is set to operate intermittently by the controller. When the cardboard passes through the counter, the high-speed blower starts. After the head end of the cardboard is pressed onto the conveyor belt 1, the controller controls the high-speed blower to stop. At this time, the air outlet nozzle 8 will not blow up the tail end of the cardboard until the next cardboard passes through the infrared counter. Repeat the above actions.

[0035] The specific start-up and shutdown times of the high-speed blower are set according to the conveying speed of the conveyor belt.

[0036] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be thought of without creative efforts should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
