[0013] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] Refer to Figure 1-2, this specific embodiment adopts the following technical solution: a new type of foot-operated pneumatic cardboard cutting machine, including a machine frame 1, a loading table 2, a vertical baffle 3, a pressure roller 4, an upper knife 5, a lower knife 6, a fixed-scale baffle 7, a cylinder 8, a connecting mechanism 9, a spring 10, a pneumatic solenoid valve 11 and a foot switch 12. The machine frame 1 is fixed with a loading table 2, and a vertical baffle 3, a pressure roller 4, an upper knife 5, a lower knife 6 and a fixed-scale baffle 7 are installed on the loading table 2. The upper knife 5 and the lower knife 6 are arranged between the vertical baffle 3 and the fixed-scale baffle 7, and the upper knife 5 is located above the lower knife 6. The pressure roller 4 is installed between the upper knife 5 and the vertical baffle 3. The upper knife 5 is connected to the connecting mechanism 9, the connecting mechanism 9 is installed under the loading table 2, the connecting mechanism 9 is connected to the piston rod of the cylinder 8, and the connecting mechanism 9 is also connected to the loading table 2 through a spring 10; the cylinder 8 is connected to the pneumatic solenoid valve 11, the pneumatic solenoid valve 11 is fixed on the machine frame 1, and the pneumatic solenoid valve 11 is connected to the foot switch 12; a tool clearance adjustment device 13 for adjusting the clearance between the upper and lower knives is also installed on the loading table 2, and the clearance between the upper knife 5 and the lower knife 6 is adjusted by the bolt on the tool clearance adjustment device 13 to make the knife clearance reach the optimal state.
[0015] It should be noted that two springs 10 are provided, symmetrically installed at the two short rod ends of the connecting mechanism 9. The lower end of the spring 10 is connected to the connecting mechanism 9, and the upper end of the spring 10 is fixed to the bottom surface of the loading table 2. The connecting mechanism 9 is pulled by the spring 10 to lift the upper knife 5 back to its original position.
[0016] In addition, the foot switch 12 and the coil of the pneumatic solenoid valve 11 are connected in series to the 220V switch power supply 14. The foot switch 12 is in the normally open state. When the foot steps on the foot switch 12, the switch is in the conducting state. When the foot releases the foot switch 12, the switch is in the open state. The circuit is switched on and off by stepping on and releasing the foot switch 12.
[0017] In this specific embodiment, the pressure roller 4, the vertical baffle 3 and the fixed-scale baffle 7 play a key role in positioning and deforming and irregular cardboard. Among them, the pressure roller 4 can make the cardboard enter the shearing straight, the vertical baffle 3 can make the cardboard always enter the shearing at 90°, and the fixed-scale baffle 7 can be adjusted according to actual requirements and keep the cut paper corner guard in a right angle.
[0018] When this specific embodiment works, the raw material paper corner guard is placed on the loading table 2, close to the vertical baffle 3, flattened by the pressure roller 4 and sent into the cutting edge to the fixed-scale baffle 7. The opening and closing of the pneumatic solenoid valve 11 are controlled by stepping on the foot switch 12, so as to control the extension of the cylinder 8. The force of the extension of the cylinder 8 is transmitted to the upper knife 5 through the connecting mechanism 9, so that the upper knife 5 presses down to generate a shearing force with the lower knife 6, thereby cutting off the paper corner guard. Specifically, its working principle is as follows:
[0019] On the basis that the slitter is equipped with a 220V switching power supply 14 and a 0.7Mpa air source, place the raw material hard paper corner guard on the loading table 2, lean it to the left against the vertical baffle 3, make the hard paper corner guard perpendicular to the cutting edge of the upper knife 5, and then push it forward. The pressed roller 4 flattens and straightens the bent hard paper corner guard to facilitate passing smoothly through the upper knife 5 and the lower knife 6. When it is pushed to the fixed scale baffle 7 with the cutting length adjusted, step on the foot switch 12. The switch is in a conducting state, triggering the pneumatic solenoid valve 11 installed on the frame 1 to open. The coil of the pneumatic solenoid valve 11 is energized, and the coil iron core generates magnetic force, causing the pilot valve to act. Compressed air enters the cylinder 8, thereby pushing the piston of the cylinder 8 to do work. The piston ejector rod pushes the connecting mechanism 9 to pull down the upper knife 5 downward, generating a shearing force with the lower knife 6, thus cutting the hard paper corner guard; when the operator's foot releases the foot switch 12, the switch is in an open circuit state, and the pilot valve resets under the action of the internal spring of the solenoid valve. The spring 10 pulls the connecting mechanism 9, and the cylinder 8 is pulled back to the initial state. At the same time, the upper knife 5 is lifted, completing the entire shearing process.
[0020] This specific embodiment is safe, efficient, time-saving and labor-saving in shearing, greatly improving the shearing quality of special-shaped cardboard, increasing production efficiency, and at the same time reducing labor costs. The small corner guard products produced by this slitter have a high degree of consistency in specifications, are suitable for shearing deformed or irregular cardboard, and have broad market application prospects.
[0021] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
