[0023] See also Figures 1-6 A positioning and cutting device for processing melamine impregnated paper includes a supporting mechanism 1 and a positioning mechanism 2 and a cutting mechanism 3 arranged on the top thereof. The supporting mechanism 1 includes a supporting platform 101:

[0024] Furthermore, the positioning mechanism 2 includes a clamping member 206 correspondingly arranged on the front and rear sides of the top of the support platform 101, and the clamping member 206 includes a mounting plate 207, and the bottom of the mounting plate 207 is slidingly connected to the top of the support platform 101, and the left and right sides of the top of the mounting plate 207 are rotatably connected to the first rotating rod 208, and one end of the first rotating rod 208 is rotatably connected to the clamping plate 209, and the opposite side of the clamping plate 209 is in contact with the front and rear sides of the impregnated paper, and the other end of the first rotating rod 208 is slidably connected to the round table push block 210, and one side of the round table push block 210 is fixedly connected to the second rotating rod 211, and the second rotating rod 211 is threadedly connected to the mounting plate 207, and a first spring 212 is connected between the top of the first rotating rod 208.

[0025] The support mechanism 1 provides a stable platform foundation, namely the support table 101, which is used to carry and position the melamine impregnated paper to be cut. The clamping members 206 are respectively located on the front and rear sides of the support table 101, and are slidably connected to the top of the support table 101 through the mounting plate 207. They can be flexibly adjusted according to the width of the impregnated paper. When the second rotating rod 211 is rotated, the round table push block 210 will push the first rotating rod 208 to move, thereby adjusting the pressure of the clamping plate 209 on the impregnated paper. At the same time, the function of the first spring 212 is to maintain appropriate contact pressure between the clamping plate 209 and the impregnated paper when no external force is applied, which can ensure that the paper is effectively clamped and avoid damage to the paper surface or resin layer by excessive tightening. The front and rear sides of the impregnated paper are adhered and clamped by the clamping plate 209 to achieve precise positioning of the paper. The device realizes flexible positioning and moderate clamping of the impregnated paper through the above structure, which helps to improve cutting accuracy and product quality, and reduces the defective rate caused by paper movement or deformation.

[0026] Furthermore, a threaded sleeve 204 is fixedly connected to the bottom of the mounting plate 207, and the threaded sleeve 204 extends to the bottom of the support platform 101 and is slidably connected thereto. The inner wall of the threaded sleeve 204 is threadedly connected to a bidirectional threaded rod 201, and one end of the bidirectional threaded rod 201 is fixedly connected to a power motor 203.

[0027] When the power motor 203 is started, the positions of the two clamping members 206 can be synchronously adjusted by rotating the bidirectional threaded rod 201 to adapt to melamine-impregnated paper of different widths. The power motor 203 is used to drive the clamping members 206 to achieve rapid and precise adjustment of the spacing between the clamping members 206, greatly improving production efficiency and positioning accuracy. It is particularly suitable for batch production of melamine-impregnated paper cutting operations. At the same time, the electric control method is also more convenient for docking with the automation control system of the entire production line.

[0028] Furthermore, guide grooves 102 are correspondingly opened on the front and rear sides of the top of the support platform 101 , and the guide grooves 102 are slidably connected to the threaded sleeve 204 . The bottom of the support platform 101 is fixedly connected to the base 103 .

[0029] The threaded sleeve 204 will slide along the guide groove 102 during the movement. This design further improves the stability and accuracy of the movement of the mounting plate 207 and the clamping member 206, ensuring that there will be no shaking or deviation during the entire adjustment and positioning process, effectively ensuring the accurate positioning of the melamine impregnated paper. The base 103 serves as the basic support of the entire device. On the one hand, it bears the weight of the entire positioning and cutting device. On the other hand, it also transmits the force generated during the cutting process to the ground, ensuring the stability of the device during operation, reducing the adverse effects of vibration, and thus improving cutting quality and production safety.

[0030] Furthermore, the front and rear ends of the bidirectional threaded rod 201 are rotatably connected to fixed plates 202 , which are fixedly arranged at the bottom of the support platform 101 , and one side of the fixed plate 202 is fixedly connected to a power motor 203 .

[0031] The fixing plate 202 is fixedly arranged at the bottom of the support platform 101. The purpose of doing so is to provide a stable rotation fulcrum for the bidirectional threaded rod 201 to ensure its stability during rotation. At the same time, it also limits the radial displacement of the bidirectional threaded rod 201, ensuring that the bidirectional threaded rod 201 can only perform rotational motion, thereby effectively converting it into a linear reciprocating motion of the mounting plate 207.

[0032] Furthermore, the inner wall of the threaded sleeve 204 is slidably connected to a limiting rod 205 , and the limiting rod 205 is fixedly disposed at the bottom of the support platform 101 .

[0033] The inner wall of the threaded sleeve 204 is also slidably connected to a limit rod 205, which is fixedly arranged at the bottom of the support platform 101. The main function of this limit rod 205 is to provide a limit guide for the moving range of the mounting plate 207, preventing the threaded sleeve 204 and the mounting plate 207 from deviating from the correct trajectory when following the rotation and movement of the bidirectional threaded rod 201, ensuring that the clamping member 206 can move back and forth accurately and smoothly within the set range to adapt to melamine impregnated paper of different widths.

[0034] Furthermore, the cutting mechanism 3 includes a U-shaped frame 301, the bottom of the U-shaped frame 301 is fixedly connected to the front and rear sides of the support platform 101, the top of the U-shaped frame 301 is fixedly connected to an electric push rod 302, the movable end of the electric push rod 302 extends to the bottom of the U-shaped frame 301 and is fixedly connected to a connecting plate 303, the bottom of the connecting plate 303 is fixedly connected to a plurality of positioning seats 304, and the bottom of the positioning seat 304 is fixedly connected to a cutter 305.

[0035] When the electric push rod 302 receives the command, it will drive the connecting plate 303 to move up and down, thereby driving all the cutters 305 to move synchronously, so as to achieve precise cutting of the melamine impregnated paper placed on the support table 101. The entire cutting process can be automated through the precise control of the electric push rod 302, which not only improves the cutting efficiency, but also because the installation position and cutting depth of the cutter 305 are adjustable, the impregnated paper can be cut in a diversified and high-precision manner according to different needs. At the same time, this structural design is also conducive to the maintenance and replacement of the cutter 305, thereby improving the overall convenience of the equipment.

[0036] Furthermore, a sliding rod 306 is fixedly connected to the front and rear sides of the top of the connecting plate 303. The top of the sliding rod 306 extends above the U-shaped frame 301 and is slidably connected to it. A second spring 307 is movably sleeved on the surface of the sliding rod 306 and is fixedly connected between the U-shaped frame 301 and the connecting plate 303.

[0037] Driven by the electric push rod 302, the connecting plate 303 can drive the slide bar 306 to rise or fall smoothly and stably, ensuring the vertical and stable movement of the cutter 305 during the cutting process, preventing shaking or tilting during the cutting process. After the cutter 305 completes the cutting, the rebound force of the second spring 307 helps the connecting plate 303 to reset smoothly. At the same time, it can also absorb part of the impact force generated by the material cutting, thereby reducing the operating noise of the equipment, extending the service life of the equipment, and further ensuring the stability and accuracy of the cutting process.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
