[0035] When the equipment is running, the user places the polyvinyl chloride sheet 9 to be processed on a pair of belt conveyors 42, and uses the belt conveyors 42 to convey the polyvinyl chloride sheet 9 to between the baffle 43 and the top port of the dust cover 3; then, the second linear module 413 of a pair of lifting assemblies 41 drives the sliding bracket 412 to descend along the axial direction of the assembly shell 1, and the sliding bracket 412 drives the baffle 43 to descend synchronously. When the sliding bracket 412 descends to a certain height, the polyvinyl chloride sheet 9 is lifted up by the dust cover 3, and the baffle 43 abuts against the polyvinyl chloride sheet 9, and the baffle 43 and the dust cover 3 are used to clamp and position the polyvinyl chloride sheet 9; next, the cutting device 23 is started, and the two-dimensional translation slide 241 drives the cutting device 23 to move radially along the assembly shell 1.

The sheet debris with a smaller volume is sucked into the water tank 6 along with the air flow and is finally captured by the aqueous solution accumulated in the water tank 6. After the ring cutting process is completed, the user can open the hatch 13 to obtain the processed polyvinyl chloride sheet 9 that falls on the sieve plate 22 through the hatch 13.

[0037] During the circular cutting process of the polyvinyl chloride sheet 9, the user can adjust the descending height of the sliding bracket 412 by controlling the second linear module 413, so that the user can use the baffle 43 to press down the polyvinyl chloride sheet 9, so that the polyvinyl chloride sheet 9 squeezes the first flexible spring sheet 31 and the second flexible spring sheet 32, and adjusts the width of the air intake channel 33, thereby achieving the purpose of adjusting the airflow intensity flowing through the air intake channel 33 into the inner cavity of the assembly shell 1.

[0038] Above, refer to Figures 1 to 7 The polyvinyl chloride sheet ring cutting device according to the embodiment of the present invention is described, which has the following beneficial effects: 1. The device arranges the processing module inside the assembly shell 1 and arranges the dust cover 3 at the top port of the assembly shell 1, so that during the ring cutting process of the polyvinyl chloride sheet 9, the top port of the dust cover 3 abuts against the bottom surface of the polyvinyl chloride sheet 9 and corresponds to the processing area of ​​the polyvinyl chloride sheet 9, so as to prevent the debris generated by the ring cutting process of the polyvinyl chloride sheet 9 from splashing to the outside of the assembly shell 1, thereby solving the problem of poor debris splash prevention effect in the prior art, and significantly improving the phenomenon of sheet debris accumulation at the cutting position of the polyvinyl chloride sheet 9, so as to facilitate the user to clean the polyvinyl chloride sheet 9 after the ring cutting process.

[0039] 2. The device is provided with a slag discharge pipe 5 at the bottom of the assembly shell 1 and an end cover 51 at the bottom of the slag discharge pipe 5, so that the user can open the end cover 51 and use the slag discharge pipe 5 to discharge the aqueous solution and plate debris accumulated inside the assembly shell 1, the reflux channel 7 and the water tank 6, thereby facilitating the user to clean the plate debris.

[0040] 3. The device adopts a dust cover 3 composed of a plurality of first flexible spring sheets 31 and a plurality of second flexible spring sheets 32 which are shorter than the first flexible spring sheets 31 and are arranged in an alternating manner, and uses a baffle 43 and the dust cover 3 to support and position the polyvinyl chloride sheet 9, which not only ensures the positioning effect of the device on the polyvinyl chloride sheet 9 during the ring cutting process of the polyvinyl chloride sheet 9, but also enables the first flexible spring sheets 31, the second flexible spring sheets 32 and the polyvinyl chloride sheet 9 to form an air inlet channel, and uses the airflow flowing through the air inlet channel to blow off the sheet debris attached to the bottom surface of the polyvinyl chloride sheet 9. Secondly, the user can also adjust the deformation degree of the first flexible spring sheets 31 and the second flexible spring sheets 32 by controlling the descending height of the baffle 43, thereby achieving the purpose of changing the width of the air inlet channel 33 and adjusting the airflow strength flowing into the inner cavity of the assembly shell 1 through the air inlet channel 33, and further enhancing the effect of blowing off the sheet debris attached to the bottom surface of the polyvinyl chloride sheet 9.
