It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 3 The present invention provides a technical solution: an automatic cutting saw for cutting plastic sheets, comprising: a frame 1, mounting plates 7 are fixedly installed on both sides of the lower part of the frame 1, and a driving mechanism 2 is provided on one side of the mounting plate 7; a plastic sheet limiting mechanism 8, the plastic sheet limiting mechanism 8 includes a guide rod 81, the guide rod 81 is symmetrically fixedly mounted on one side of the mounting plate 7 close to each other, and a double-headed screw 82 is rotatably installed in the middle of the side close to each other. Both sides of the outer circumference of the double-headed screw 82 are threadedly connected to a moving plate 811. A limiting block 84 is fixedly installed on the top of the moving plate 811, and a clamping groove 813 is opened in the middle of the side close to each other. When the plastic sheet is placed in the clamping groove 813, the driving mechanism 2 can drive the double-headed screw 82 to rotate. Since the outer circumference threads of the double-headed screw 82 rotate in opposite directions, under the cooperation of the threads, the moving plate 811 will drive the limiting block 84 to move axially along the guide rod 81, and then the clamping groove 813 will limit and fix the plastic sheet, which is convenient for the plastic sheet cutting piece 5 to cut the plastic sheet.

[0023] The middle part of the slot 813 is symmetrically slidably installed with a movable rod 87, and the end of the movable rod 87 on the same side away from the mounting plate 7 is fixedly installed with an abutment plate 83, and the end of the movable rod 87 away from the abutment plate 83 is rotatably installed with a connecting rod 2 88, and the end of the connecting rod 2 88 away from the movable rod 87 is rotatably installed with a connecting rod 1 86, and the end of the connecting rod 1 86 away from the connecting rod 2 88 is fixedly installed with a limit plate 85, and the outer periphery of the movable rod 87 is provided with a spring 812, and the middle part of the connecting rod 2 88 is rotatably installed with a rotating shaft 89, and the bottom end of the rotating shaft 89 is respectively fixedly installed on the limit block 84 on the same side, and the limit block 84 is fixedly installed with a pin 810 at the front and rear. It is rotatably installed on the pin shaft 810 on the same side, and one end of the spring 812 is fixedly installed on the side of the abutment plate 83 on the same side close to the limit block 84, and the other end of the spring 812 is fixedly installed in the slot 813 on the same side. When the limit blocks 84 approach each other, the plastic plate will push the abutment plate 83 in the slot 813 to move, and then the movable rod 87 will drive the connecting rod 1 86 and the connecting rod 2 88 to swing, so that the limit plate 85 will abut against the other two sides of the plastic plate, which can enhance the limiting effect of the plastic plate. At the same time, a spring 812 is provided on the outer periphery of the movable rod 87, which can facilitate the abutment plate 83 to wait for the movable rod 87 to be driven to reset, so as to facilitate the next limiting fixation.

[0024] The top of the frame 1 is symmetrically fixed with a guide rail 3, and a movable frame 4 is slidably installed in the guide rail 3. A plastic sheet cutting piece 5 is provided in the middle of the movable frame 4. The plastic sheet cutting piece 5 includes two cylinders 51, and the cylinder 51 is symmetrically fixed in the middle of the movable frame 4. The driving end of the cylinder 51 is fixedly installed with a mounting frame 52, and a cutting saw blade 53 is provided in the middle of the mounting frame 52. The movable plate 811 is slidably installed on the guide rod 81, and an electric push rod 6 is fixedly installed in the middle of the other side of the top of the frame 1. The driving end of the electric push rod 6 is fixedly installed on the movable frame 4. By controlling the cylinder 51, the cylinder 51 can drive the cutting saw blade 53 to move downward. When the cutting saw blade 53 approaches the plastic sheet, the driving part in the mounting frame 52 can drive the cutting saw blade 53 to rotate to cut the plastic sheet. In addition, the electric push rod 6 can adjust the position of the plastic sheet cutting piece 5, which can facilitate the staff to cut the plastic sheet at different positions.

[0025] The driving mechanism 2 includes a stepper motor 23, which is fixedly mounted on the lower part of one side of the frame 1. A driving wheel 24 is fixedly mounted on the driving end of the stepper motor 23. The driving wheel 24 drives the driven wheel 22 to rotate through a belt 21. The driven wheel 22 is fixedly mounted on one end of the double-headed screw 82. By controlling the stepper motor 23, the stepper motor 23 can drive the driving wheel 24 to rotate. Since the driving wheel 24 is connected to the driven wheel 22 through the belt 21, the driven wheel 22 can drive the double-headed screw 82 to rotate. With the cooperation of the thread, the movable plate 811 can drive the limit block 84 to move toward each other, which can facilitate the staff to limit and fix different plastic sheets.

[0026] During actual use, the staff places the plastic sheet to be cut on the limit block 84, and then the stepper motor 23 in the driving mechanism 2 cooperates with the active wheel 24, the driven wheel 22 and the belt 21 to realize the rotation of the double-headed screw 82, and then the movable plate 811 can drive the limit block 84 to move. At the same time, in conjunction with the movable rod 87, the abutment plate 83, the connecting rod 1 86 and the connecting rod 2 88, the limit plate 85 can be driven to approach the plastic sheet, thereby increasing the limiting effect of the plastic sheet and avoiding the plastic sheet from shaking during the cutting process, affecting the cutting accuracy. After the fixation is completed, the electric push rod 6 can drive the plastic sheet cutting piece 5 to move, thereby completing the cutting of the plastic sheet.
