[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Combination Figures 1 to 4The positioning device of a film production crimping machine shown in the figure includes an upper module 1, a lower module 2 and a cylinder 3 located on the top of the upper module 1 and fixedly connected, a plurality of guide rods 4 are provided between the upper module 1 and the lower module 2 and are connected by welding, a mounting plate 5 is provided above the lower module 2 and is connected by screws, an arc-shaped workbench 51 is provided above the mounting plate 5 and is connected by screws, a knife drop groove 52 is provided on the arc-shaped workbench 51, trapezoidal mounting seats 53 are fixedly connected on both sides of the arc-shaped workbench 51, a laser receiver 54 is installed inside the trapezoidal mounting seats 53, and a limiting roller group 6 is provided on the side of the lower module 2.
[0023] Among them, a pressure plate 11 is arranged below the upper module 1, the top of the pressure plate 11 is fixedly connected to the output end of the cylinder 3, a fixing plate 12 is installed below the pressure plate 11, and a cutting knife 13 is installed below the fixing plate 12. The pressure plate 11 is used to bear the output pressure of the cylinder 3 and connect the cylinder 3 and the cutting knife 13 at the same time;
[0024] Laser emitters 7 are fixedly arranged on both sides of the fixing plate 12. A plurality of laser heads with lamp heads facing downward are fixedly arranged inside a single laser emitter 7. The laser receiver 54 is provided with light receiving holes with the same number as the laser heads. The laser beam emitted by the laser emitter 7 is irradiated, and then the laser receiver 54 receives these lights and performs corresponding positioning according to the receiving state. When the film is offset and blocks part of the light receiving holes, the transmission and reception of the laser are blocked and this information is sent to the control system of the equipment, and the corresponding stop operation is immediately executed to stop the operation of the equipment.
[0025] The limiting roller group 6 includes a limiting roller 61, and support blocks 62 are provided at both ends of the limiting roller 61. The two support blocks 62 are connected to the lower module 2 by screws. The limiting roller 61 and the support blocks 62 are connected by a rotating shaft. The film passes through the bottom of the limiting roller 61, and the height difference between the arc-shaped workbench 51 and the bottom of the limiting roller 61 generates pressure to tighten the film.
[0026] Both ends of the outer side of the limiting roller 61 are fixed with limiting rings 63 higher than the surface of the limiting roller 61, and the limiting rings 63 limit the position of the film from both sides of the film;
[0027] A through hole matching the guide rod 4 is provided inside the pressure plate 11, and the guide rod 4 passes through the pressure plate 11 through the through hole, so that the pressure plate 11 drives the cutting knife 13 to perform vertical reciprocating motion along the direction of the guide rod 4;
[0028] A connecting block 41 is provided at the lower part of the guide rod 4 , and the connecting block 41 is connected to the guide rod 4 and the mounting plate 5 by screws. A triangular notch 42 is provided on the connecting block 41 to facilitate blowing away the debris in the knife groove 52 from the triangular notch 42 .
[0029] Working principle: When the utility model is in use, after the equipment is started, the cylinder will begin to provide the required pressure to make the pressure plate drive the cutting knife to perform vertical reciprocating motion along the direction of the guide rod. The pressure plate is subjected to the output pressure of the cylinder and transmits the pressure to the cutting knife to make the cutting knife perform vertical reciprocating motion to cut the film. The laser transmitter above the workbench emits a laser beam, and the laser receiver determines the position of the film by detecting the receiving state of the laser. If the film deviates or blocks the laser beam, the receiver will send a signal to the control system to trigger the corresponding shutdown operation to ensure the accuracy of the film position. The bottom of the limiting roller contacts the film through the arc workbench. Due to the height difference between the arc workbench and the bottom of the limiting roller, pressure is generated on the film, and the film is tightened to ensure its stability during the cutting process.
