The upper end surface of the pad 7 is flush with the upper end surface of the base 1. A lever 70 is vertically provided on the upper end surface of the pad 7.
[0030] The working principle of this utility model is as follows: like Figures 1 to 4 As shown, before use, first screw the shielding frame 2 onto the base 1, then insert the connecting rod 30 into the first opening 201 on the shielding frame 2, and attach one side of the handle 51 to the connecting rod 30 at the insertion end, and then insert the insertion end of the connecting rod 30 onto the other side of the shielding frame 2.
[0031] Then, the lower end face of the tension spring 33 is fixed to the upper end face of the guide block 31, and the guide block 31 is vertically placed into the shielding frame 2 from bottom to top. At the same time, the left and right sides of the guide block 31 in the upward direction are respectively placed in the guide channel 23 formed by the two protruding pillars 232 and the two bent sections 231, so that the guide block 31 can move in a directional manner on the shielding frame 2; at this time, the tension spring 33 is also located in the guide channel 23. Figure 2 (At the position of the dashed circle in the middle); then, the upper end face of the tension spring 33, which is fixedly connected to the guide block 31, is also fixedly connected to the lower end face of the cover 21, and the upper and lower fixed connection positions of the tension spring 33 are all fixed by spot welding; place the cover 21 at the second opening 202 position at the upper end of the shielding frame 2, at this time, the cover plate 25 is placed at the first opening 201 position, and the bolt 212 is inserted through the through hole 211, and the protruding end of the bolt 212 is screwed into the threaded hole 221 to screw the cover 21 onto the shielding frame 2; at the same time, the position of the tension spring 33 is shielded, which can effectively prevent impurities from entering, and the lower end face of the protrusion 511 is abutted against the upper end face of the guide block 31.
[0032] Finally, according to the paper specifications, the positions of the first limiting plate 41 and the second limiting plate 42 need to be adjusted. Since the included angle of the paper is usually set as a right angle, the included angle between the two limiting blocks is also set to a 90° angle value. Similarly, the included angle between the two directional grooves 45 of the guide limiting block is also a 90° angle value. Push the paper from the direction of the limiting block towards the shielding frame 2. When the paper moves to the position below the rounded corner cutter 32, pull down the handle 51. The protrusion 511 abuts against the guide block 31 and pushes the guide block 31 down, thereby stretching the tension spring 33 and causing the blade of the rounded corner cutter 32 to approach the upper end surface of the paper, thereby adjusting the rounded corner cutter 32 to align with the processing position mark on the paper.
[0033] Then, move the two limit blocks together to the outer wall of the paper, tighten the locking bolt 44 on one side, start the linear motor 61, and the pressure rod 62 drives the pressure block 63 to move down and press the paper. Then pull the handle 51 to move the rounded cutter 32 down to check if the processing position is offset so that it can be adjusted further. If there is no offset, immediately tighten the locking bolt 44 on the other side. This completes the positioning adjustment before processing.
[0034] During processing, the paper is pushed from the direction of the limiting block towards the shielding frame 2. After the paper moves to the position below the rounded corner cutter 32 and simultaneously abuts against the limiting blocks on both sides, the linear motor 61 is started. The pressure rod 62 drives the pressure block 63 to move down and press down the paper. Then, the handle 51 is pulled down, and the protrusion 511 abuts against the guide block 31 and pushes the guide block 31 down, thereby stretching the tension spring 33 and driving the blade of the rounded corner cutter 32 to move down to cut the paper. After cutting, the handle 51 is released. Under the elastic force of the tension spring 33, the handle 51 is driven to move up to the initial position to wait.
[0035] After repeated use, one side of the pad 7 is damaged by the impact of the rounded corner cutter 32. In order to effectively protect the cutting effect of the blade, the lever 70 is moved to rotate the pad 7 clockwise in the concave hole, so as to achieve the purpose of changing the side of the pad 7. At the same time, the movement position of the lever 70 is not within the range of paper movement. When the pad 7 is rotated to the correct position, it does not affect the paper feeding. Furthermore, when the pad 7 needs to be replaced, the lever 70 can be pulled upward to remove the pad 7 for replacement.
[0036] In order to prevent the handle 51 from moving upward under the inertia of the elastic force of the tension spring 33 and causing the cover 21 to spring up, threaded holes 221 are also provided on the two protrusions 232, and the two protrusions 232 and the two mounting blocks 22 are arranged in a rectangular shape. That is, four through holes 211 arranged in a rectangular shape are provided on the cover 21. Correspondingly, four bolts 212 are also provided. In this way, the four bolts 212 are screwed into the threaded holes 221 to ensure the installation stability of the cover 21.
[0037] like Figures 1 to 4 As shown, in order to ensure the stability of the handle 51 during the pulling process and to provide clearance and auxiliary limit for the movement of the guide block 31, two handles 51 are arranged in parallel and connected as one piece by a connecting pin (not shown). The cover plate 25 is located between the two handles 51, and the width of the linear motor 61 is also smaller than the distance between the two handles 51 to avoid interference. Other installation structures are the same as those described above, and the appropriate installation state will not be described again here.
[0038] It should be noted that a placement groove (not shown) is provided on the lower end face of the guide block 31, and a base plate (not shown) is provided at the bottom of the rounded corner cutter 32, which is placed in the placement groove. The base plate and the placement groove are fixed by fixing bolts to realize the fixed connection between the rounded corner cutter 32 and the guide block 31, and also to facilitate the replacement of rounded corner cutters 32 of different specifications.
[0039] When disassembly is required, simply knock the connecting rod 30 out of the shielding frame 2, pull the handle 51 horizontally out at the first opening 201 of the shielding frame 2, and finally remove the bolt 212 and lift the cover 21, which will bring out the tension spring 33 and the guide block 31.
