[0024] Reference Figures 1 to 7 In this embodiment of the present invention, a cutting device for a mask machine includes: an operating table 1 and a dust collection mechanism 2. The operating table 1 is the basic platform for the entire cutting operation, and the dust collection mechanism 2 is used to remove dust and waste generated during the cutting process to keep the working environment clean. A cylinder 3 is fixedly connected to one end of the top of the operating table 1, and a cylinder 10 is fixedly connected to the other end of the top of the operating table 1. Both cylinder 3 and cylinder 10 play a lifting and lowering role.

[0025] The movable end of cylinder 13 is equipped with a transverse cutting mechanism 4 for transverse cutting of mask material, and the movable end of cylinder 210 is equipped with a longitudinal cutting mechanism 5 for longitudinal cutting of mask material. One end of the outer side of the operating table 1 is fixedly connected to a motor 6, one end of the inner side of the operating table 1 is rotatably connected to a lead screw 7, and the other end of the inner side of the operating table 1 is slidably connected to a connecting base 8. When the motor 6 drives the lead screw 7 to rotate, the connecting base 8 will move along the axial direction of the lead screw 7.

[0026] The transverse cutting mechanism 4 is equipped with a flattening mechanism 9. The function of the flattening mechanism 9 is to flatten the mask material before cutting to ensure that the cut mask has a regular shape and accurate size. There are two sets of motor 6, lead screw 7 and connecting base 8. The other end of lead screw 7 passes through the operating table 1 and is fixedly connected to the output end of motor 6. Lead screw 7 and connecting base 8 are threaded together. There are two sets of flattening mechanisms 9. The other set of flattening mechanisms 9 is located inside the longitudinal cutting mechanism 5.

[0027] Reference Figure 1and Figure 3 The vacuuming mechanism 2 includes a vacuum cleaner 201, a connecting pipe 202, an elastic telescopic pipe 203, and a suction pipe 204. The vacuum cleaner 201 is the power source of the entire vacuuming mechanism 2. It sucks up dust and waste by generating negative pressure. The connecting pipe 202 is fixedly connected to one end of the vacuum cleaner 201. The elastic telescopic pipe 203 is fixedly connected to one end of the connecting pipe 202. The connecting pipe 202 is used to connect the elastic telescopic pipe 203. The elastic telescopic pipe 203 has a certain degree of elasticity and flexibility, which can adapt to the vacuuming needs of different positions. The suction pipe 204 is fixedly connected to one end of the elastic telescopic pipe 203. The suction pipe 204 further extends the vacuuming range to the working area of ​​the cutting device.

[0028] The long, flat suction nozzle 205, the limiting hook 206, and the universal brake wheel 207 are all included. The long, flat suction nozzle 205 is fixedly connected to one end of the suction tube 204. The long, flat suction nozzle 205 is used to accurately suck up dust and waste generated during the cutting process on the operating table 1. The limiting hook 206 is symmetrically fixedly connected to both sides of the long, flat suction nozzle 205. The limiting hook 206 is movably inserted into the connecting base 8. By inserting the limiting hook 206 into the connecting base 8, the long, flat suction nozzle 205 can move with the connecting base 8 to perform mobile vacuuming. The universal brake wheel 207 is fixedly connected to the bottom of the vacuum cleaner 201. The universal brake wheel 207 allows the vacuuming mechanism 2 to be easily moved and positioned.

[0029] Reference Figure 1 , Figure 5 and Figure 6 The transverse cutting mechanism 4 includes a support base 401, a second motor 402, a second lead screw 403, and a sliding base 404. The support base 401 is the main structure of the transverse cutting mechanism 4, which provides sufficient stability and support force to ensure the smooth progress of the cutting process. The second motor 402 is fixedly connected to one end of the outer side of the support base 401, and the second lead screw 403 is rotatably connected to the inner side of the support base 401. The second motor 402 serves as the power source for driving the movement of the cutting mechanism. By rotating the second motor 402, the rotation of the second lead screw 403 can be driven, thereby realizing the linear movement of the sliding base 404. The sliding base 404 is slidably connected to the other sliding base 404.

[0030] The motor housing 405, the rotating shaft 406, and the cutting blade 407 are fixedly connected to the bottom of the sliding base 404. The rotating shaft 406 is located inside the motor housing 405. The cutting blade 407 is fixedly connected to one end of the outer side of the rotating shaft 406. The rotating shaft 406 is driven to rotate by the motor housing 405, thereby driving the cutting blade 407 to rotate for cutting.

[0031] The longitudinal cutting mechanism 5 and the transverse cutting mechanism 4 have the same structure. The structure of the longitudinal cutting mechanism 5 is exactly the same as that of the transverse cutting mechanism 4, except that its cutting direction is longitudinal. The other end of the lead screw 403 passes through the support base 401 and is fixedly connected to the output end of the motor 402. The lead screw 403 is threadedly connected to the sliding base 404. The motor compartment 405 integrates a motor and gear transmission assembly and is connected to the other end of the rotating shaft 406. There are two sets of cutting blades 407, which are symmetrically arranged at both ends on the outside of the rotating shaft 406.

[0032] Reference Figure 5 and Figure 7 The flattening mechanism 9 includes an H-shaped outer shell 901 and a spring 902. The H-shaped outer shell 901 is the main structure of the flattening mechanism 9, which provides sufficient stability and support. The spring 902 is fixedly connected to the H-shaped outer shell 901 and provides elastic support.

[0033] The telescopic rod 903 and the pressure roller 904 are slidably connected to the inside of the H-shaped outer shell 901. The design of the telescopic rod 903 allows the pressure roller 904 to move up and down within a certain range to accommodate mask materials of different thicknesses. The pressure roller 904 is rotatably connected to one end of the telescopic rod 903. The pressure roller 904 is a key component of the flattening mechanism 9. It flattens the material by rolling. The other end of the spring 902 is fixedly connected to the telescopic rod 903. There are two sets of both the H-shaped outer shell 901 and the pressure roller 904, and four sets of both the spring 902 and the telescopic rod 903.

[0034] The working principle of this utility model is as follows:

[0035] Step 1: The second motor 402 drives the second lead screw 403 to rotate, thereby realizing the linear movement of the sliding base 404, which in turn drives the motor housing 405 to move. The motor housing 405 drives the rotating shaft 406 to rotate, thereby driving the cutting blade 407 to rotate and cut. In this way, the mask material can be cut laterally. The longitudinal cutting mechanism 5 operates in the same way. Then, the first cylinder 3 and the second cylinder 10 respectively raise and lower the transverse cutting mechanism 4 and the longitudinal cutting mechanism 5, thereby adjusting the height of the cutting mechanism to adapt to the cutting of mask materials of different thicknesses or positions.

[0036] Step 2: After the cutting operation, lift the two sets of cutting mechanisms upwards, and then hang the limiting hooks 206 on both sides of the long flat suction nozzle 205 on the two sets of connecting bases 8 in the operating table 1, thereby fixing the connecting bases 8 above the operating table 1. Then, drive the lead screw 7 to rotate through the motor 6, which will move the connecting bases 8 and the fixed long flat suction nozzle 205 on the table surface of the operating table 1. The flexibility of the elastic telescopic tube 203 ensures the stability and continuity of the suction efficiency. Even when the long flat suction nozzle 205 moves, it can maintain effective suction, thereby cleaning the table surface of the operating table 1 in a comprehensive and fast manner, improving cleaning efficiency.

[0037] Step 3: When cylinders 3 and 10 drive the transverse cutting mechanism 4 and the longitudinal cutting mechanism 5 to perform lifting and cutting respectively, the pressure roller 904 presses down on the mask material to prevent it from moving or deforming during the cutting process. The spring 902 provides a certain pressure to the pressure roller 904 to ensure that the pressure roller can fit tightly on the mask material. Through the connection between the telescopic rod 903 and the H-shaped outer shell 901, it can be adjusted for materials of different thicknesses. When cutting longitudinally or transversely, the pressure roller 904 is driven to roll, ensuring that it moves synchronously with the cutting blade 407 during moving cuts. It can stably press down on the mask material, ensuring the accuracy and efficiency of cutting. This not only improves the cutting quality but also improves the adaptability and stability during cutting.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
