[0055] Specifically, during the operation of the cutting device 28, the servo motor 25 drives the second screw 23 to rotate, thereby causing the second screw 23 to thread the mounting bracket 26 to move, and the mounting bracket 26 slides outside the fixing column 24 to move smoothly, thereby achieving cutting of the plastic sheet.

[0056] like Figure 5 , Figure 6 and Fig. 9 As shown, an expansion component is provided at the lower end of the electric push rod 27, and the expansion component includes a T-shaped support block 29 installed at the lower end of the electric push rod 27, four support rods 31 are fixedly connected to the outside of the T-shaped support block 29, and a funnel 30 is fixedly connected to the end of the four support rods 31 away from the T-shaped support block 29, four second springs 34 are fixedly connected to the outside of the T-shaped support block 29, and a second slider 32 is fixedly connected to the end of the four second springs 34 away from the T-shaped support block 29, and a hook 33 is fixedly connected to the lower end of the second slider 32, and the hook 33 is used to install a stretched nylon bag 36.

[0058] Working principle: when cutting the plastic sheet, after placing the plastic sheet between the rubber tooth column 6 and the rubber roller 40, the output shaft of the micro motor is used to drive the rubber tooth column 6 to rotate, and the rubber tooth column 6 cooperates with the rubber roller 40 to drive the plastic sheet to be transported. When the plastic sheet is transported to the rubber wheel 11, the rubber wheel 11 is lifted up by the plastic sheet away from the support frame 2, and the first spring 12 is used to bounce the T-shaped slide column 9 downward, and the T-shaped slide column 9 pulls the second fixing block 10 to drive the rubber wheel 11 to move downward, and then presses and fixes the plastic sheet, thereby preventing the rubber tooth column 6 from being unable to drive the plastic sheet to move and adjust the cutting area while pressing the plastic sheet. Moreover, the rubber wheel 11 can be increased according to the width of the plastic sheet, thereby facilitating pressing it, so that the cutting device 28 can better cut it, thereby solving the problem that the existing automatic plastic sheet cutting machine directly presses and fixes the plastic sheet by the pressing plate, resulting in the inability to move the plastic sheet for adjustment when the cutting area needs to be adjusted;

During the rotation of the transmission shaft 15, the first bevel gear 16 is driven to rotate, and at the same time, the first bevel gear 16 is meshed with the second bevel gear 18 to rotate, and then the second bevel gear 18 drives the first screw rod 20 to rotate, and then the first screw rod 20 threadedly drives the first slider 21 to slide in the inner cavity of the slide groove 19, and at the same time, the first slider 21 drives the T-shaped fixing block 22 to move, and then the T-shaped fixing block 22 drives the second screw rod 23 and the fixing column 24 to move, and at the same time, the second screw rod 23 drives the second screw rod 23 and the fixing column 24 to move. 23 and the fixed column 24 drive the mounting frame 26 to move, and during the movement of the mounting frame 26, the electric push rod 27 is driven to move, and the electric push rod 27 drives the cutting device 28 to move to adjust the cutting position of the plastic sheet, and after the cutting position of the plastic sheet is adjusted, the cutting device 28 is pushed upward by the output end of the electric push rod 27, and the plastic sheet is cut by the cutting device 28, and during the operation of the cutting device 28, the second screw rod 23 is driven to rotate by the servo motor 25, so that the second screw rod 23 thread-drives the mounting frame 26 to move, and the mounting frame 26 slides outside the fixed column 24 and moves smoothly, thereby realizing the cutting of the plastic sheet;

[0060] In the process of cutting the plastic sheet, the nylon bag 36 is installed on the hook 33, and then the second spring 34 is used to bounce the second slider 32 to slide outside the support rod 31 away from the T-shaped support block 29. In the process of the second slider 32 moving away from the T-shaped support block 29, the hook 33 is driven to move, and then the hook 33 drives the nylon bag 36 to open, and the waste generated by the cutting device 28 when cutting the plastic sheet will fall into the inner cavity of the funnel 30, and then the funnel 30 is used to guide the waste generated by the cutting of the plastic sheet into the inner cavity of the nylon bag 36 for storage, and in the process of cutting the plastic sheet of different sizes, the waste generated by the cutting device 28 will fall into the inner cavity of the funnel 30, and then the waste generated by the cutting of the plastic sheet will be introduced into the inner cavity of the nylon bag 36 for storage. When the small nylon bag 36 is installed and stretched, the telescopic rod 3 can be set as a synchronous push rod according to actual usage, and then the synchronous push rod can be used to push the support frame 2 to lift and adjust its height, and then the nylon bag 36 can be installed on the hook 33, and then the nylon bag 36 can be used to collect the waste generated by cutting the plastic sheet, which can also increase the storage capacity of the waste, thereby solving the problem that the existing automatic plastic sheet cutting machine is inconvenient to collect and store the waste generated by cutting the plastic sheet, causing the waste generated to affect the working environment and increase the workload of later cleaning.
