Detailed Embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Referring to Figures 1-4 , a punching device for a flame-retardant composite film, comprising a workbench 1, with frames 2 arranged on both sides of the workbench 1, and a cutter fixing seat 3 is slidably arranged above the workbench 1 for installing a punching cutter.

[0028] Both ends of the cutter fixing seat 3 are connected to the telescopic ends of electric cylinders 4, and the electric cylinders 4 are vertically installed on the frames 2. The telescopic movement of the electric cylinders 4 drives the cutter fixing seat 3 to rise and fall, so as to drive the punching cutter to punch and reset.

[0029] A plurality of cutters 32 are arranged at the lower end of the cutter fixing seat 3, and a blanking plate 321 is slidably arranged in the cutter 32, and a compression spring 322 is connected between the blanking plate 321 and the inner top wall of the cutter 32. When the cutter 32 punches the flame-retardant composite film, the composite film is pressed against the workbench 1 by the elastic force of the compression spring 322, and then the punching is carried out in cooperation with the cutter 32. After the punching is completed, the compression spring resets to drive the blanking plate 321 to extend and push out the cut waste, so as to prevent the waste from accumulating in the cutter 32 and affecting the punching effect of the cutter 32.

[0030] A pressing frame 5 is arranged on the outside of the cutter fixing seat 3, linkage frames 51 are arranged on both sides of the pressing frame 5, and an elastic linkage assembly 52 is connected between the linkage frames 51 and the telescopic ends of the electric cylinders 4. When the electric cylinders 4 extend, that is, when punching the composite film, the elastic linkage assembly 52 drives the pressing frame 5 to press the flame-retardant composite film against the workbench 1. An anti-slip buffer pad can be laid at the lower end of the pressing frame 5 to ensure the fitting effect with the composite film. By pressing the edge of the composite film by the pressing frame 5, it is ensured that the flame-retardant composite film will not stretch and move along with the cutter 32 during punching, so as to ensure the punching accuracy of the flame-retardant composite film.

[0031] Based on the above technical solutions, when punching the flame-retardant composite film, the flame-retardant composite film is sent to a specified position on the workbench 1, the electric cylinders 4 are started to extend, the pressing frame 5 first contacts the flame-retardant composite film and presses it against the workbench 1, the electric cylinders 4 continue to move downward, driving the cutters 32 to cut the composite film. At the same time, the blanking plate 321 presses the composite film to ensure the punching effect. After the punching is completed, the cutters 32 rise. Under the action of the elastic force of the compression spring 322, in cooperation with the blanking plate 321, the punched waste is pushed out of the cutters 32 to ensure the continuous punching effect of the cutters 32.

[0032] In this technical solution, as Figures 1-4 shown, the elastic linkage assembly 52 includes:

[0033] The linkage plate 521 is horizontally and fixedly sleeved on the telescopic end of the electric cylinder 4;

[0034] The guide post 522 is vertically and fixedly installed on the linkage frame 51 and penetrates through the linkage plate 521 for sliding connection therewith;

[0035] The return spring 523 is arranged between the linkage plate 521 and the linkage frame 51 and sleeved on the guide post 522.

[0036] The return spring 523 elastically connects the linkage plate 521 and the linkage frame 51, enabling the linkage frame 51 and the pressure border frame 5 to move up and down with the telescopic movement of the electric cylinder 4, ensuring the edge pressing effect of the pressure border frame 5 on the composite film to guarantee the punching quality. At the same time, in cooperation with the guide post 522, it ensures the stable vertical sliding of the linkage frame 51 and the stable lifting of the pressure border frame 5.

[0037] In this technical solution, as Figures 1-4 shown, the frame 2 includes the vertical columns 22 arranged on both sides and the top plate 21 horizontally arranged at the upper ends of the vertical columns 22. The electric cylinder 4 is vertically and fixedly installed at the lower end of the top plate 21. A plurality of sliding sleeves 511 are arranged on the outer side of the linkage frame 51, and the sliding sleeves 511 are all slidably sleeved on the vertical columns 22. Through the sliding of the sliding sleeves 511 on the vertical columns 22, the stable lifting of the pressure border frame 5 is further ensured, avoiding horizontal sliding in the horizontal direction when the pressure border frame 5 contacts the flame-retardant composite film, and avoiding displacement of the flame-retardant composite film resulting in punching deviation, so as to ensure good punching accuracy of the flame-retardant composite film.

[0038] In this technical solution, as Figures 1-4 shown, a plurality of mounting holes 31 are provided on the cutter fixing seat 3. Locking holes are correspondingly provided at the upper ends of the cutters 32, and locking bolts 311 matching the mounting holes 31 are threadedly connected in the locking holes. Through the design of the mounting holes 31, it is convenient to replace cutters 32 of different models. And through the plurality of mounting holes 31, it is convenient to install the cutters 32 at any position to meet the punching requirements at different positions.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
