However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0039] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0040] See also Figures 1 to 7 , this embodiment includes:

[0041] The sheet machine body 1 is used for producing and processing plastic sheets. The BMSJ sheet machine mainly produces BMSJ sheet molded plastics, which is a new type of thermosetting molded plastics used in transportation, construction, and electrical appliances. The BMSJ sheet machine is a production equipment for adding a polyester resin composed of a thickener, a filler, a release agent, a curing agent, etc., impregnating glass fiber yarn, and covering both sides with a film to form a sandwich structure. The appearance and size of the graphic are not based on the diagram, and are selected according to actual needs. This application does not specify the state of the sheet machine, so the details are not described in detail;

[0042] A workbench 2 is fixedly connected to the bottom end of the sheet machine body 1;

[0043] Two transverse linear motors 3 are installed on the top of the workbench 2. The moving parts of the two transverse linear motors 3 are commonly connected to an inverted U-shaped connecting plate 4. Two first vertical electric push rods 5 are embedded in the top of the connecting plate 4. The sides of the moving parts of the two first vertical electric push rods 5 are connected to side support plates 6. The sides of the two side support plates 6 are commonly connected to lifting ears 7. The lifting ears 7 are connected to a U-shaped fixed clamping plate 8 through a rotating shaft. A forward and reverse motor 9 for providing power to the rotating shaft is installed on the side of the lifting ear 7. An auxiliary electric push rod 10 is embedded in the side of the fixed clamping plate 8. The moving part of the auxiliary electric push rod 10 is connected to a movable clamping plate 11 for cooperating with the fixed clamping plate 8 to clamp and fix the plastic sheet. The transverse linear motor 3 is controlled to drive the connecting plate 4 to move, so that the fixed clamping plate 8 and the movable clamping plate 11 are directly below the plastic sheet at the guide assembly 26. , by adjusting the first vertical electric push rod 5, changing the height of the fixed clamping plate 8 and the movable clamping plate 11, the fixed clamping plate 8 and the movable clamping plate 11 are aligned with the plastic sheet, the auxiliary electric push rod 10 is extended, the movable clamping plate 11 is moved, and the plastic sheet is clamped and fixed with the fixed clamping plate 8. After clamping, the first vertical electric push rod 5 is controlled to retract and reset, and the horizontal linear motor 3 is controlled to drive the connecting plate 4 to move away from the guide component 26 and pull it to the specified position. The forward and reverse motors 9 rotate the fixed clamping plate 8 to change the direction of the movable clamping plate 11 and rotate it to a horizontal state. At this time, the plastic sheet remains in a taut state of pulling. If it is not in a taut state, when pulling, various operations are performed in the middle. After adjustment, the horizontal linear motor 3 continues to pull, so as to pull to the specified position, so that the plastic sheet is in a taut state;

[0044] The inverted U-shaped auxiliary plate 12 is fixedly connected to the top of the workbench 2 and is located between the guide assembly and the connecting plate 4. The two vertical inner walls of the auxiliary plate 12 are both equipped with vertical linear motors 13. The moving parts of the two vertical linear motors 13 are commonly connected to an upper fixed frame 14. A second vertical electric push rod 15 is embedded in the top of the auxiliary plate 12. The moving part of the second vertical electric push rod 15 is connected to a cutting knife 16 for cutting the plastic sheet. After the plastic sheet is pulled, the third vertical electric push rod 15 is connected to the upper fixed frame 14. The electric push rod 17 is extended to drive the lower fixed frame 18 to move upward, and the vertical linear motor 13 drives the upper fixed frame 14 to move downward. When the plastic sheet is not affected, the plastic sheet is fixed. At this time, the second vertical electric push rod 15 is extended to drive the cutting knife 16 to move downward, and then the plastic sheet is automatically cut. After the cutting is completed, the auxiliary electric push rod 10, the second vertical electric push rod 15, and the third vertical electric push rod 17 are controlled to reset, and the fixed plastic sheet falls onto the conveyor 24;

[0045] Two third vertical electric push rods 17 are embedded in the top of the workbench 2. The tops of the moving parts of the two third vertical electric push rods 17 are commonly connected to a lower fixed frame 18 adapted to the upper fixed frame 14. The top of the upper fixed frame 14 and the bottom of the lower fixed frame 18 are both bonded with rubber pads 19. The heights of the top of the upper fixed frame 14 and the lower fixed frame 18 ensure that the connecting plate 4, the fixed splint 8 and the first vertical electric push rod 5 can pass through normally.

[0046] For guiding, a guide assembly 26 for guiding the plastic sheet is installed on the top of the workbench 2, and the guide assembly 26 includes:

If it is the first cutting, the plastic sheet at the sheet machine body 1 can be manually passed through the two guide rollers 203 of the guide assembly 26 and dropped to one side of the guide roller 203. If it is not the first cutting, it can be directly operated.

[0049] In order to carry out recording, a plurality of vertical support plates 20 are installed on the top of the workbench 2 , and cameras 27 for recording are installed on the top of the vertical support plates 20 and the sides of the mounting frame 202 .

[0050] A plurality of supporting legs 21 are welded to the bottom end of the workbench 2, a counterweight circular plate 22 is welded to the bottom end of the supporting legs 21, and a plurality of circular holes for bolts to pass through are formed at the top end of the counterweight circular plate 22.

[0051] In order to carry out transportation and adjustment, a mounting groove is opened at the top of the workbench 2, and the inner wall of the mounting groove of the workbench 2 is rotatably connected with a mounting plate 23 through a rotating shaft. A conveyor 24 for conveying plastic sheets is installed on the top of the mounting plate 23, and a servo motor 25 for providing power for the rotating shaft is installed on the outer periphery of the workbench 2. The released plastic sheet falls onto the conveyor 24, and the servo motor 25 drives the rotating shaft and the mounting plate 23 to rotate, thereby changing the inclination angle of the conveyor 24, and the conveyor 24 can convey the plastic sheets.

[0052] The length of the cutting knife 16 is greater than the length of the plastic sheet, and is less than the inner diameter length of the lower fixing frame 18 and the upper fixing frame 14 . A scale line is provided on the top of the workbench 2 .

The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0054] How it works

[0055] The cutting device for the sheet material machine, if it is the first cutting, can manually pass the plastic sheet at the sheet material machine body 1 through the two guide rollers 203 of the guide assembly 26, and fall to one side of the guide roller 203, control the horizontal linear motor 3 to drive the connecting plate 4 to move, so that the fixed clamping plate 8 and the movable clamping plate 11 are directly below the plastic sheet at the guide assembly 26, by adjusting the first vertical electric push rod 5, change the height of the fixed clamping plate 8 and the movable clamping plate 11, so that the fixed clamping plate 8 and the movable clamping plate 11 are aligned with the plastic sheet, the auxiliary electric push rod 10 is extended to move the movable clamping plate 11, and cooperate with the fixed clamping plate 8 to clamp and fix the plastic sheet, after clamping, control the first vertical electric push rod 5 to retract and reset, control the horizontal linear motor 3 to drive the connecting plate 4 to move away from the guide assembly 26, and pull it to At the specified position, the forward and reverse motors 9 rotate the fixed clamping plate 8 to change the direction of the movable clamping plate 11 and rotate it to a horizontal state. After the plastic sheet is pulled, the third vertical electric push rod 17 extends to drive the lower fixed frame 18 to move upward, and the vertical linear motor 13 drives the upper fixed frame 14 to move downward. Without affecting the plastic sheet, the plastic sheet is fixed. At this time, the second vertical electric push rod 15 extends to drive the cutting knife 16 to move downward, and then the plastic sheet is automatically cut. After the cutting is completed, the auxiliary electric push rod 10, the second vertical electric push rod 15, and the third vertical electric push rod 17 are controlled to reset, and the fixed plastic sheet falls onto the conveyor 24. The servo motor 25 drives the rotating shaft and the mounting plate 23 to rotate, changing the inclination angle of the conveyor 24, and the conveyor 24 can transport the plastic sheet.
