Description

Technical Field

[0001] The utility model belongs to the technical field of plate production and manufacturing equipment, in particular to an automatic plate film cutting machine. Background Art

[0002] Film cutting is a process in the production of elevator enclosures, which involves cutting the film encapsulated on the surface of the sheet. During the film cutting process, the film cutting distance and the spacing between the edges of the enclosure need to be accurately measured, and then the tool is used to cut along a straight line. However, it is impossible to accurately measure the distance manually, and it is impossible to strictly control the tool to cut along a straight line. In addition, the tool is also prone to scratching the sheet due to improper force during the cutting process. Automatic film cutting equipment can not only accurately control the knife position and cut strictly according to the designed trajectory, but also is not easy to scratch the sheet, greatly improving production efficiency and product quality.

[0037] The working principle and workflow of this utility model are:

[0038] When the plate arrives at the film cutting machine and the photoelectric proximity switch A detects the plate, the plate conveying unit 5 starts working to convey the plate to the target position; at the same time, the X-axis positioning drive 602 starts to move and extend, raising the X-axis positioning baffle 603; when the photoelectric proximity switches B and C detect the plate at the same time, the Y-axis positioning drive 605 starts to move, driving the Y-axis first positioning baffle 604 to move in the direction close to the Y-axis second positioning baffle 607, thereby realizing the clamping positioning of the plate.

[0039] After positioning is completed, the two X-axis moving unit servo motors 201 operate simultaneously, driving the two X-axis moving unit slides 203 to move synchronously, so that the Y-axis moving unit slide 304 moves along the X-axis direction, adjusting the position of the Y-axis second cutting unit 403 in the X-axis direction, and then adjusting the distance between the Y-axis first cutting unit 401 and the Y-axis second cutting unit 403 to achieve the adjustment of the film cutting width in the X-axis direction; the Y-axis moving unit servo motor 303 drives the Y-axis moving unit slide 304 to move along the Y-axis direction, adjusting the position of the X-axis first cutting unit 402 in the Y-axis direction, and then adjusting the distance between the X-axis first cutting unit 402 and the X-axis second cutting unit 404 to achieve the adjustment of the film cutting width in the Y-axis direction. After the width adjustment of the film to be cut is completed, the tool telescopic driving member 406 of the X-axis first cutting unit 402 and the X-axis second cutting unit 404 drives the cutting tool 405 to extend and act on the film, and the two X-axis moving unit servo motors 201 drive the two X-axis moving unit slides 203 to move synchronously, so that the X-axis first cutting unit 402 and the X-axis second cutting unit 404 move along the X-axis to realize film cutting in the X-axis direction; after the film cutting in the X-axis direction is completed, the tool telescopic driving member 406 of the X-axis first cutting unit 402 and the X-axis second cutting unit 404 drives the cutting tool 405 to retract. Then, the tool telescopic driving member 406 of the Y-axis first cutting unit 401 and the Y-axis second cutting unit 403 drives the cutting tool 405 to extend and act on the film, and the Y-axis moving unit servo motor 303 drives the Y-axis moving unit slide 304 to move, so that the Y-axis first cutting unit 401 and the Y-axis second cutting unit 403 move along the Y-axis to achieve film cutting in the Y-axis direction; after the film cutting in the Y-axis direction is completed, the cutting props 405 of the Y-axis first cutting unit 401 and the Y-axis second cutting unit 405 are retracted to avoid scratching the plate.

[0040] After the film cutting is completed, the X-axis positioning drive 602 contracts to reset the X-axis positioning baffle 603, and the Y-axis positioning drive 605 drives the Y-axis first positioning baffle 604 to move away from the Y-axis second positioning baffle 607. The plate positioning module 6 no longer clamps the plate. At this time, the plate conveying unit 5 continues to convey the plate that has completed the film cutting to the next process.
