DETAILED DESCRIPTION

[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1-Figure 4 A PVC board cutting device shown in the figure comprises a base 1, a cutting mechanism 2 is arranged on the top of the base 1; a fixed structure 3, the fixed structure 3 is arranged on the top of the base 1, and the fixed structure 3 is used to fix the PVC board; an auxiliary structure 4, the auxiliary structure 4 is arranged inside the fixed structure 3, and the auxiliary structure 4 is used to prevent the PVC board from being damaged by excessive extrusion; wherein the fixed structure 3 comprises two support blocks 301 fixedly connected to the top of the base 1 and symmetrically distributed, two connecting blocks 313 are fixedly connected to the opposite back surfaces of the two support blocks 301, two pressure rods 310 are arranged on the top of the support blocks 301, and a connecting rod 309 is fixedly connected between the two pressure rods 310, a guide rod 312 is fixedly connected to the top of one of the connecting blocks 313, and a threaded rod 311 is rotatably connected to the top of the other connecting block 313, and the upper ends of the guide rod 312 and the threaded rod 311 both penetrate the adjacent pressure rods 310;

[0019] The PVC board is placed on the top of the two support blocks 301, and the pressure rod 310 connected thereto can be driven downward by rotating the threaded rod 311. During this process, the pressure rod 310 on the other side can be driven downward synchronously by the connecting rod 309, so as to fix the PVC board. After the PVC board is fixed, the PVC board is cut by the cutting mechanism 2. The cutting mechanism 2 is a common technical means in this field, and the purpose of cutting is achieved by using a motor to drive the cutting disc to rotate, which will not be described in detail here.

[0020] The top of the support block 301 is provided with a mounting groove 302, the inner wall of the mounting groove 302 is slidably connected with a slider 303, the upper end of the slider 303 passes through the mounting groove 302, the top of the slider 303 is embedded with evenly distributed suction cups 304, and the bottom of the suction cups 304 is connected with a connecting pipe 305;

[0021] When the PVC board is placed on the top of the support block 301 , it can shield the suction cup 304 , so that the suction cup 304 is not connected to the outside world.

[0022] The base 1 is provided with a plurality of mounting tubes 306 corresponding to the connecting tubes 305. The inner wall of the mounting tube 306 is slidably connected with a sealing plate. A first spring 308 is fixedly connected between the bottom of the sealing plate and the inner wall of the mounting tube 306. An adjusting cavity is formed between the top of the sealing plate and the inner wall of the mounting tube 306.

[0023] The first spring 308 is provided to ensure the normal position of the sealing plate.

[0024] The lower end of the connecting pipe 305 passes through the supporting block 301, the base 1 and the adjacent mounting tube 306 in sequence and is fixedly connected to the top of the sealing plate. A connecting hole 307 communicating with the regulating cavity is provided on the surface of the connecting pipe 305.

[0025] When the pressure rod 310 is used to fix the PVC board, the PVC board pushes the slider 303 to slide down along the inner wall of the installation groove 302. During this process, the slider 303 can drive the connecting tube 305 to gradually insert into the interior of the installation tube 306, and at the same time drive the sealing plate to move down to squeeze the first spring 308, so that the internal space of the adjustment cavity is increased, and a negative pressure space is formed compared to the outside. Since the adjustment cavity is connected with the connecting tube 305 through the connecting hole 307, the connecting tube 305 can generate suction through the suction cup 304 to adsorb the PVC board, thereby enhancing the fixing effect of the PVC board and effectively preventing the position displacement of the PVC board during the cutting process from affecting the cutting effect.

[0026] The auxiliary structure 4 includes a push rod 401 slidably connected to the inner wall of the support block 301, one end of the push rod 401 passes through the support block 301 and corresponds to the adjacent threaded rod 311, the other end of the push rod 401 passes through the support block 301 and extends to the inside of the mounting groove 302, and a trigger wedge surface 402 is provided at one end of the push rod 401 away from the threaded rod 311.

[0027] A second spring 403 is fixedly connected to the surface of the support rod 401, and the other end of the second spring 403 is fixedly connected to the inner wall of the support block 301;

[0028] In the process of fixing the PVC board by the action of the fixing structure 3, the trigger wedge surface 402 of the push rod 401 can be squeezed by the downward movement of the slider 303, so that it is away from the slider 303 and the second spring 403 is squeezed. In this process, the push rod 401 can apply pressure to the threaded rod 311 until the top surface of the slider 303 is flush with the top surface of the support block 301. At this time, the bottom surface of the PVC board and the top surface of the support block 301 are just released, and at the same time, the push rod 401 is tightly against the threaded rod 311 so that the threaded rod 311 cannot continue to rotate, so that the PVC board can be fixed, avoiding damage caused by excessive squeezing under the hard contact between the PVC board and the support block 301;

[0029] Working principle: Place the PVC board on the top of the two support blocks 301, and by rotating the threaded rod 311, the pressure rod 310 connected thereto can be driven to move downward. In this process, the pressure rod 310 on the other side can be driven to move downward synchronously through the connecting rod 309, so as to fix the PVC board. In the process of the PVC board moving downward, the slider 303 can be driven to slide down along the inner wall of the installation groove 302 synchronously. Since the PVC board blocks the suction cup 304, the slider 303 can drive the connecting pipe 305 to gradually insert into the interior of the installation cylinder 306, and at the same time drive the sealing plate to move downward to squeeze the first spring 308, so that the internal space of the adjustment cavity is increased, and a negative pressure space is formed compared to the outside. Since the adjustment cavity is connected with the connecting pipe 305 through the connecting hole 307, it can generate suction through the suction cup 304 under the action of the connecting pipe 305 to adsorb the PVC board, thereby strengthening the fixing effect of the PVC board and effectively preventing the position deviation of the PVC board during the cutting process from affecting the cutting effect. At the same time, under the action of the auxiliary structure 4, it can prevent the PVC board from being damaged by excessive extrusion under the hard contact with the support block 301.
