Blank key DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-3 As shown, the embodiment of the present invention provides a blank key film cutting assembly, comprising:

[0026] a supporting frame 1;

[0027] A translation clamping assembly is mounted on the support frame 1 and includes a sliding track 2, a horizontally movable sliding seat 3 is slidably connected to the sliding track 2, and a pneumatic finger 4 is fixed to the bottom of the sliding seat 3;

[0028] A hot-pressed easy-tear forming assembly, comprising a connecting frame 5 on which a liftable hot-pressed easy-tear forming device is provided;

[0029] An unwinding assembly, comprising an upper film unwinding mechanism 6 and a lower film unwinding mechanism 7, wherein the upper film unwinding mechanism 6 comprises an upper connecting seat 8 fixed to the support frame 1, and the upper film roll is rotatably connected between the upper connecting seats 8; the lower film unwinding mechanism comprises a lower connecting seat 10, and the lower film roll is rotatably connected between the lower connecting seats 10;

[0030] A cutting assembly is located above the translation clamping assembly and includes a liftable cutting knife 11.

[0031] The process of using the present invention is as follows: the upper film unwinding structure and the lower film unwinding mechanism are respectively connected to the upper film roll and the lower film roll, and the starting end of the lower film roll is pulled out horizontally, and the starting end of the upper film roll is passed around the tensioning roller 9 and pulled out horizontally, so that the upper film roll is located above the lower mold roll, and the starting ends of the upper film roll 23 and the lower mold roll 24 remain overlapped. Then, the clamping hand of the previous process clamps the blank key and places it between the upper film roll and the lower film roll, and starts the hot pressing easy-tear forming component. The upper film roll and the lower film roll in the blank key area are hot pressed by the hot pressing easy-tear forming component. Press and form an easy-to-tear edge at the same time of hot pressing. After a blank key is coated, the translation clamping assembly is started so that the pneumatic fingers 4 on the sliding seat 3 clamp the upper film roll and the lower film roll and move them backward at intervals. The moving distance each time is 3-4 cm. Then the next blank key is placed between the upper film roll and the lower film roll again, and the above action is repeated. When enough blank keys are reached, the cutting assembly is started and the continuous film is cut by lifting the cutting knife 11. After the cutting is completed, the sliding seat 3 moves to the front end again to clamp the film, and finally repeats the above action.

[0032] Furthermore, the pneumatic fingers 4 are fixed on the sliding seat 3, and the number thereof is 2. Specifically, the pneumatic fingers 4 of the present invention are two, so that the film can be clamped firmly.

[0033] Furthermore, the translation clamping assembly further includes a drive motor 12, which is connected to a synchronous belt 13 via a main synchronous belt 13 wheel. The sliding seat 3 is fixedly connected to the synchronous belt 13 via a clamping component. The support frame 1 is also connected to a secondary synchronous belt 13 wheel via a side plate 16 and a bearing seat 14. Specifically, the translation clamping assembly of the present invention includes a drive motor 12, which drives the synchronous belt 13 to rotate via the main synchronous belt 13 wheel. When the synchronous belt 13 rotates, the sliding seat 3 is driven to move, thereby achieving movement of the film.

[0034] Furthermore, the hot-pressed easy-tear-forming device includes a hot-pressing cylinder 17, below which are fixed a hot-pressing block 19 and an easy-tear-forming blade 18. Specifically, the present invention uses the hot-pressing cylinder 17 to drive the hot-pressing block 19 downward, while simultaneously forming the easy-tear-forming blade 18. The hot-pressed easy-tear-forming device is an existing structure and will not be described in detail here.

[0035] Furthermore, the cutting assembly includes a cutting cylinder 20, and the cutting blade 11 is fixed to the cutting cylinder 20. The cutting edge 21 of the cutting blade 11 is a bevel. Specifically, the cutting assembly of the present invention is driven by the cutting cylinder 20. The cutting blade 11 is fixed to the cutting cylinder 20, and its cutting edge 21 is a bevel, which facilitates cutting of the film.

[0036] Furthermore, the support frame 1 is fixed on a bottom plate 22, and the bottom plate 22 is fixed with a lower connecting seat 10. Specifically, by setting the bottom plate 22, the support frame 1 is more stable, and the lower connecting seat 10 is more firmly connected through the bottom plate 22.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
