DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0026] Reference Figure 1-6 , an anti-indentation paper cutter comprises a workbench 1, a protective pad 2 and a main bracket 4 are arranged on the workbench 1, a groove perforation 21 is opened on the protective pad 2, a damping ring 22 and a stud cap 3 are arranged in the groove perforation 21, a finger buckle groove 30 and a stud 31 are arranged on the stud cap 3, a controller 41 and a paper cutting cylinder 42 are arranged on the main bracket 4, a paper cutting knife 43 is arranged on the paper cutting cylinder 42, a grinding cylinder 8 is arranged above the workbench 1, a first rotating shaft 80 and a second rotating shaft 81 are arranged on the grinding cylinder 8, a transverse cylinder 44 is arranged on the main bracket 4, an adjusting sleeve 5 is arranged on the transverse cylinder 44, an adjusting slide rod 6 is slidably connected in the adjusting sleeve 5, a compensating spring 61 and a mounting bracket 7 are arranged on the adjusting slide rod 6, a motor 71 is arranged on the mounting bracket 7, the protective pad 2 is made of glass fiber material with a thickness of fifteen millimeters, has the characteristics of high strength, high wear resistance, corrosion resistance, etc., and can effectively disperse the cutting pressure.
[0027] The outer wall of the grinding cylinder 8 has a grinding surface, which is similar to the surface of a grinding stone, and can perform high-speed rotation grinding and polishing on the left and right cutting surfaces of the paper cutter 43.
[0028] In detail, the first rotating shaft 80 is fixedly arranged with the motor shaft of the motor 71, and the second rotating shaft 81 is rotatably arranged with the mounting frame 7. The motor 71 is combined with the first rotating shaft 80 and the second rotating shaft 81 to drive the grinding cylinder 8 to rotate at a high speed.
[0029] Furthermore, the controller 41 is electrically connected to the paper cutting cylinder 42 , and the cross section of the adjusting slide bar 6 is a T-shaped structure, which can prevent the adjusting slide bar 6 from slipping out of the adjusting slide cavity 51 .
[0030] The controller 41 is preset with a PLC, which can control the piston rod of the paper cutting cylinder 42 to move up and down at a constant speed according to a certain vertical distance, and can also control the piston rod of the paper cutting cylinder 42 and drive the paper cutter 43 to move downward to cut the hard paper on the protective pad 2.
[0031] Furthermore, an adjusting slide cavity 51 is provided in the adjusting sleeve 5, and the two ends of the compensating spring 61 are respectively fixed to the inner wall of the adjusting slide cavity 51 and the adjusting slide rod 6. When the grinding cylinder 8 contacts the left and right cutting surfaces of the paper cutter 43, the compensating spring 61 itself is in a compressed state. Since the left and right cutting surfaces of the paper cutter 43 are inclined surfaces, the compensating spring 61 in the compressed state can ensure that the grinding cylinder 8 is always rotating and polishing along the left and right cutting surfaces of the paper cutter 43 at high speed to achieve the compensating effect.
[0032] In more detail, a screw groove 11 is opened on the workbench 1, and the stud 31 passes through the groove through hole 21 and is threadedly connected to the screw groove 11. The stud cap 3 and the stud 31 form a group, and there are four groups symmetrically arranged in total. The four groups of studs 31 improve the installation stability of the protective pad 2.
[0033] Generally speaking, the upper end surface of the stud cap 3 is not higher than the sink hole 21, so as to avoid the stud cap 3 protruding and affecting the horizontal laying effect of the hard paper.
[0034] The finger buckle grooves 30 are arc-shaped inner grooves and are arranged in a circle. The five arc-shaped inner grooves just fit the five fingers on a hand for insertion. The studs 31 can be disassembled and assembled without a screwdriver, which is very convenient.
[0035] Finally, a damping ring 22 is provided on the inner groove wall of the groove perforation 21, and the damping ring 22 is extruded and sleeved with the outer wall of the stud cap 3. The damping ring 22 is made of NBR nitrile rubber, which has high elastic damping and anti-slip properties. It can be damped and extruded with the outer wall of the stud cap 3 to prevent the stud cap 3 from rotating on its own, thereby ensuring the installation stability of the protective pad 2.
[0036] Working method: first start the controller 41, the PLC in the controller 41 will control the piston rod of the paper cutting cylinder 42 to move back and forth at a constant speed at a certain vertical distance, thereby driving the paper cutting knife 43 to move back and forth at a constant speed at a certain vertical distance, and then start the transverse cylinders 44 on both sides, driving the adjustment sleeves 5, the mounting frame 7, and the grinding cylinder 8 on both sides to move closer as a whole, and after the grinding cylinder 8 effectively contacts the cutting surfaces at the left and right ends of the paper cutting knife 43, stop the transverse cylinder 44, and then start the motor 71, drive the grinding cylinder 8 to rotate at a high speed and perform effective symmetrical grinding and polishing on the cutting surfaces at the left and right ends of the paper cutting knife 43 that is moving back and forth at a constant speed, and after the grinding and polishing of the cutting surfaces at the left and right ends of the paper cutting knife 43 are completed, the grinding cylinders 8 on both sides and the paper cutting knife 43 are reset and stopped,
[0037] Then, the hard paper to be cut is placed on the protective pad 2, and the controller 41 is started. The PLC in the controller 41 will control the piston rod of the paper cutting cylinder 42 to move downward quickly for a certain cutting distance, thereby driving the paper cutter 43 to move downward quickly for a certain cutting distance. After the paper cutter 43 cuts the hard paper on the protective pad 2, the PLC in the controller 41 will control the paper cutter 43 to move upward and reset and stop. During the cutting process, the smoothly polished paper cutter 43 ensures the smoothness of the cutting of the hard paper and avoids indentations. At the same time, the protective pad 2 can effectively disperse the cutting pressure of the paper cutter 43 to avoid indentations caused by cutting, thereby improving the anti-indentation property of the paper cutting device used for cutting hard paper as a whole, thereby improving the aesthetics of the finished hard paper.
[0038] In addition, when the protective pad 2 is worn out after being used for a long time and needs to be replaced, the finger is inserted into the finger groove 30 and rotated counterclockwise, driving the stud 31 to rotate counterclockwise and exit the screw groove 11 and be easily removed, so that the old protective pad 2 can be removed and then a new protective pad 2 can be installed, thereby improving the convenience of replacing the protective pad 2.
[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
