Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to an anti-wear feeding mechanism of a film die-cutting machine. Background Art

[0002] Die-cutting machine is also called die-cutting machine, cutting machine, CNC punching machine, mainly used for die-cutting of some corresponding non-metallic materials, self-adhesive, EVA, double-sided tape, electronics, mobile phone pads, etc. The working principle is to use die-cutting knife, steel knife, hardware mold, steel wire, and apply a certain pressure through the embossing plate to roll and cut the printed product or cardboard into a certain shape. It is often used in the production process of film;

[0003] When the film is conveyed forward with the feed roller, the film is prone to wrinkles during the release and conveying process from the film roll, resulting in the width being unable to correspond to the feed roller during the travel process, thereby tilting, causing the film in transit to tilt toward the bracket or frame, causing wear. It is for this reason that we have proposed an anti-wear feeding mechanism for the film die-cutting machine. Utility Model Content

[0026] Example:

[0027] See also Figure 1-5 , the utility model provides a technical solution of a wear-resistant feeding mechanism of a film die-cutting machine: comprising a conveyor 1 and a feeding roller 2;

[0028] The feed roller 2 is arranged at the right end of the conveyor 1, and a conveyor belt is arranged on the conveyor 1, and the conveyor belt transmits from right to left;

[0029] The feed roller 2 includes an upper clamping roller 5 and a lower clamping roller 6, a feed port 4 is reserved between the upper clamping roller 5 and the lower clamping roller 6, and the feed port 4 is parallel to the top surface of the conveyor belt;

[0030] The front and rear ends of the upper clamping roller 5 and the lower clamping roller 6 are both provided with mounting frames 3, the mounting frames 3 are rotatably connected with the upper clamping roller 5 and the lower clamping roller 6, and the connection between the mounting frames 3 and the upper clamping roller 5 and the lower clamping roller 6 is provided with a positioning ring;

[0031] One end of the mounting frame 3 close to the conveyor 1 is fixed to the conveyor 1, and the upper mounting frame 3 extends obliquely downward and is fixed with bolts;

[0032] The lower mounting frame 3 extends obliquely upward, and a mounting panel is provided at one end close to the conveyor 1, and the mounting panel is fixed to the conveyor 1 by bolts;

[0033] A smoothing frame 8 is provided on the left side of the upper clamping roller 5. The smoothing frame 8 is a rectangular frame welded together. Both left and right ends of the smoothing frame 8 are provided with mounting shafts 11. The mounting shafts 11 are rotatably mounted on the inner side of the upper clamping roller 5.

[0034] A smoothing roller 10 is disposed transversely at the bottom of the smoothing frame 8. The smoothing roller 10 is a solid cylinder, and the edges of the cylinder are all passivated. The smoothing frame 8 extends downward to the top of the feed port 4.

[0035] The upper clamping roller 5 is fixedly installed, and reinforcement rods 12 are arranged at both ends of the upper clamping roller 5 near the mounting frame 3, and both ends of the reinforcement rod 12 are welded to the mounting frame 3 and the upper clamping roller 5 respectively;

[0036] A leveling frame 7 is arranged on the right side of the upper clamping roller 5, and leveling wheels 9 are arranged equidistantly at the bottom of the leveling frame 7. The leveling wheels 9 extend obliquely downward and extend to the top of the feed port 4.

[0037] The left and right ends of the leveling frame 7 are also provided with mounting shafts 11, and the mounting shafts 11 there are also rotatably connected to the inner side of the upper clamping roller 5;

[0038] A reinforcing rod is connected between the leveling frames 7, and the reinforcing rod is a hollow metal rod body;

[0039] The feeding mechanism in this scheme can smooth the surface of the film and reduce wrinkles during use, thereby reducing the damage of the film caused by wrinkles. Specifically, a feeding roller 2 is arranged on the right side of the conveyor 1. The feeding roller 2 is an upper clamping roller 5 and a lower clamping roller 6 that are symmetrical to each other. The lower clamping roller 6 is rotatably installed and rotates with the friction when the film is fed; the upper clamping roller 5 is fixedly installed, and reinforcement rods 12 are welded at both ends so that the upper clamping roller 5 does not rotate with the advancement of the film;

[0040] During operation, the film is conveyed to the conveyor belt through the feed port 4, and is conveyed to the left as the conveyor belt rotates. The film passing through is first squeezed and flattened by the flattening wheel 9. The wheel surface of the flattening wheel 9 contacts the top surface of the film downward, and rolls synchronously with the conveyance of the film to perform preliminary flattening on the surface of the film.

[0041] Then, the film passes through the upper clamping roller 5 and the lower clamping roller 6 and is flattened again by the smoothing rod 8 on the upper left side. A smoothing roller 10 is arranged at the bottom of the smoothing rod 8. The smoothing roller 10 passes over the surface of the film and scrapes the bulges and warped edges of the film to flatten the film as much as possible. The flattened film is more neat, which is conducive to reducing the loss of the wrinkled parts.

[0042] At the same time, the smoothing rod 8 is rotatably installed. When the force applied by the film is too large, the smoothing rod 8 swings along the forward direction of the film driven by the installation shaft 11 to prevent the surface of the film from being scratched and affecting subsequent production.
