Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] During the process of cutting the copper clad laminate, a cutting mechanism needs to be used. The cutting mechanism provided by the present invention is specifically used to cut the material by the meshing of the upper circular knife 105 and the lower circular knife 305 for the copper clad laminate. The cutting efficiency is high, and all the cutting points of the circular rotating blade are evenly distributed. Therefore, the blade wear is small and uniform, and the replacement period is longer. During the use of this mechanism, it is necessary to perform inspection and installation and other preparatory work in advance to ensure the normal use of this mechanism.

[0021] As Figures 1 - 5 shown, the present invention provides a technical solution: an adjustable passive cutting mechanism with meshing, including an installation vertical plate 1. A reference tool rest assembly is arranged on the installation vertical plate 1. The reference tool rest assembly includes a first fixed cylinder 101 fixed in the middle of the bottom surface of the installation vertical plate 1, and an installation cross plate 102 fixed on one side of the bottom surface of the installation vertical plate 1. A first rotating rod is rotatably inserted into the first fixed cylinder 101. A first sleeve block 103 is sleeved and fixed on the front surface of the first rotating rod. An upper circular knife 105 is sleeved and installed on the front surface of the first sleeve block 103. A first installation pressing plate 106 is installed on the front surface of the upper circular knife 105. The back end of the first rotating rod is connected to a driving motor 104, and the driving motor 104 is installed on the first fixed cylinder 101. An adjustment tool rest assembly is arranged below the installation vertical plate 1. A connection assembly is arranged between the adjustment tool rest assembly and the reference tool rest assembly. Among them, the driving motor 104 adopts a servo motor with a self-locking function in the prior art. The whole mechanism adopts a welding process to ensure the stability of the overall structure and is not easy to loosen. After the overall welding is completed, stress relief annealing treatment is carried out to reduce the welding deformation of the whole mechanism.

[0022] In the embodiment, the connection assembly includes a vertical block 2 fixed on the front side of the bottom surface of the installation cross plate 102. A connection cross plate 201 is arranged on the bottom surface of the vertical block 2. The installation cross plate 102, the connection cross plate 201 and the vertical block 2 are fixed as a whole. The adjustment tool rest assembly includes a placement cross plate 3 arranged on the bottom surface of the connection cross plate 201. A second fixed cylinder 301 is fixed on one side of the placement cross plate 3. A second rotating rod 303 is rotatably inserted into the second fixed cylinder 301. Among them, the reference tool rest assembly is the installation reference of this mechanism.

[0023] In an embodiment, a second collar block 304 is sleeved and fixed on the front side of the second rotating rod 303. A lower circular cutter 305 is sleeved and installed on the front of the second collar block 304. A second mounting pressure plate 306 is installed on the front of the lower circular cutter 305. The lower circular cutter 305 meshes with the upper circular cutter 105. Mounting strip-shaped holes 302 are symmetrically formed on the placing cross plate 3. The mounting strip-shaped holes 302 are V-shaped. Corresponding through holes are formed on the connecting cross plate 201. Shaft holes are formed on both the connecting cross plate 201 and the placing cross plate 3. The connecting cross plate 201 and the placing cross plate 3 are adjustably connected through the shaft holes, corresponding through holes, mounting strip-shaped holes 302 and bolts. Among them, the upper circular cutter 105 and the lower circular cutter 305 adopt circular blades. When the circular blades rotate, all cutting points are evenly distributed. Therefore, the circular blades have small and uniform wear, and the replacement period is longer.

[0024] In an embodiment, the upper circular cutter 105 and the first mounting pressure plate 106 are installed on the first collar block 103 through bolts. The lower circular cutter 305 and the second mounting pressure plate 306 are installed on the second collar block 304 through bolts. Mounting opposite holes are symmetrically formed on the mounting vertical plate 1. Among them, this mechanism is made of carbon steel or stainless steel, so as to adapt to different processing environments respectively. Through the setting of the reference tool rest assembly and the adjusting tool rest assembly, the upper circular cutter 105 and the lower circular cutter 305 are used to cut the copper clad laminate material in a meshing manner, so that the service life and replacement time of the upper circular cutter 105 and the lower circular cutter 305 are extended. Moreover, the upper circular cutter 105 and the lower circular cutter 305 are simple and quick to replace, thus saving the time for shutdown maintenance and improving production efficiency. The adjusting tool rest assembly is adjustable in the horizontal direction and circumferential direction, which is convenient for adjusting the meshing angle and meshing distance with the upper circular cutter 105. The interiors of the upper circular cutter 105 and the lower circular cutter 305 are supported by bearings, enabling more flexible rotation. It is convenient to replace the upper circular cutter 105 and the lower circular cutter 305. Just remove the bolts on the first mounting pressure plate 106 and the second mounting pressure plate 306 to replace them. After replacement, it can be directly used without re-calibration.

[0025] Working principle: When using this device, the whole mechanism is installed and adjusted. According to needs, the placing cross plate 3 and the second fixed cylinder 301 as a whole are rotated by a certain angle around the shaft hole, so as to adjust the circumferential position of the lower circular cutter 305. After the adjustment is completed, the rotation of the upper circular cutter 105 will drive the lower circular cutter 305 to perform rotary cutting operation. The cutting efficiency is high, and the upper circular cutter 105 and the lower circular cutter 305 have small and uniform wear, so that the replacement period is longer.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended embodiments and their equivalents.
