[0025] Schematic protective structure of the film cutting knife of the laminating machine

[0026] Reference Figure 2 , according to a protective structure of the film cutting knife of a laminating machine in a preferred embodiment of the present utility model, which is installed on the laminating machine and includes a knife seat body 10, a knife wheel 20 and a trigger assembly 30.

[0027] Specifically, the knife seat body 10 has a receiving groove 101, the knife wheel 20 is slidably disposed in the receiving groove 101, the trigger assembly 30 is installed on the knife seat body 10, and the trigger assembly 30 includes a plurality of electromagnets 301. When the electromagnets 301 are energized or de-energized, the knife wheel 20 extends a predetermined distance out of the notch of the receiving groove 101 or the knife wheel 20 is placed in the receiving groove 101.

[0028] It should be noted that under normal conditions, the electromagnet 301 is de-energized, and the cutter wheel 20 is completely immersed in the accommodation groove 101 under the action of external elastic force. At this time, when the operator replaces the film on the upper film cylinder, even if the arm contacts the cutter seat body 10, it will not be scratched by the cutter wheel 20. When working, the operator first makes the cutter seat body 10 contact the film on the upper film cylinder. It should be pointed out that the electromagnet 301 is electrically connected to the film laminating machine power supply in series. When the film laminating machine works, the electromagnet 301 is energized at the same time. The electromagnet 301 exerts an adsorption force on the cutter wheel 20 and makes the cutting edge of the cutter wheel 20 extend a predetermined distance out of the accommodation groove 101. Then, the cutting edge of the cutter wheel 20 will contact and cut the film on the upper film cylinder. It is easy to see that compared with the prior art in which the cutter wheel 20 extends a predetermined distance out of the notch of the accommodation groove 101 under normal conditions, in the embodiment of the present application, by sliding the cutter wheel 20 on the cutter seat body 10 and arranging the trigger assembly 30, the advantages of placing the cutter wheel in the cutter seat under normal conditions, extending the cutter wheel out of the cutter seat during work, and avoiding scratching the operator by the cutter wheel are realized.

[0029] Further, to realize the sliding arrangement of the cutter wheel 20 in the accommodation groove 101, both side walls of the accommodation groove 101 are provided with a sliding groove 102. The protective structure of the film cutting knife of the film laminating machine further includes a wheel shaft 40. The cutter wheel 20 is installed on the wheel shaft 40, and both ends of the wheel shaft 40 are slidably arranged on the sliding groove 102.

[0030] It should be noted that nuts 401 are threadedly connected to both ends of the wheel shaft 40. The groove length of the sliding groove 102 is greater than the diameter of the wheel shaft 40. The groove width of the sliding groove 102 is greater than or equal to the diameter of the wheel shaft 40, and the groove width of the sliding groove 102 is less than the maximum radial dimension of the nut 401. In addition, in the embodiment of the present application, the sliding groove 102 is a kidney-shaped groove.

[0031] Further, to realize that the cutter wheel 20 is immersed in the accommodation groove 101 under normal conditions, a first installation groove 1021 and a second installation groove 1022 are respectively provided on both end walls of each sliding groove 102. The trigger assembly 30 further includes a plurality of elastic members 302. The elastic members 302 are further implemented as springs. One elastic member 302 is provided in each first installation groove 1021, and one electromagnet 301 is provided in each second installation groove 1022. The wheel shaft 40 is located between the elastic member 302 and the electromagnet 301, and both ends of the elastic member 302 are connected to the wheel shaft 40 and the bottom wall of the first installation groove 1021 by welding.

[0032] It should be noted that when the electromagnet 301 is energized and adsorbs the wheel shaft 40, the adsorption force of the electromagnet 301 on the wheel shaft 40 is greater than the elastic force of the elastic member 302, and the elastic member 302 is in a stretched state. After the electromagnet 301 loses power, the electromagnet 301 no longer exerts an adsorption force on the wheel shaft 40, and the wheel shaft 40 is immersed in the accommodation groove 101 again under the action of the elastic force of the elastic member 302.

[0033] Further, to ensure that after the electromagnet 301 adsorbs the wheel shaft 40, the cutting edge of the cutter wheel 20 can extend a predetermined distance from the notch of the accommodation groove 101, when the electromagnet 301 loses power, the distance between the wheel shaft 40 and the electromagnet 301 is greater than the distance between the cutting edge of the cutter wheel 20 and the notch of the accommodation groove 101.

[0034] Further, the protection structure of the film cutting knife of the film laminating machine further includes two intermediate members 50. Both of the intermediate members 50 are rotatably mounted on the wheel shaft 40 through bearings and are symmetrically arranged. Two sides of the cutter wheel 20 are respectively clamped with the two intermediate members 50.

[0035] More specifically, to realize the clamping of the cutter wheel 20 and the intermediate member 50, both sides of the cutter wheel 20 are respectively provided with a plurality of clamping grooves 201, and both sides of the two intermediate members 50 facing each other are respectively provided with a plurality of protrusions 501. The protrusions 501 correspond to the clamping grooves 201 one by one, and each protrusion 501 is clamped with the corresponding clamping groove 201.

[0036] Further, to limit the axial movement of the bearing, a shaft shoulder 402 and a snap ring groove 403 are provided in the middle section of the wheel shaft 40. Both of the intermediate members 50 are located between the shaft shoulder 402 and the snap ring groove 403. It should be noted that a snap ring is provided in the snap ring groove 403. The inner ring of one bearing abuts against the shaft shoulder 402, and the inner ring of the other bearing abuts against the snap ring in the snap ring groove 403. In addition, both ends of the two intermediate members 50 facing away from each other are respectively provided with a bearing groove 502, and each bearing groove 502 is in interference fit with the outer ring of the corresponding bearing.

[0037] In summary, the protection structure of the film cutting knife of the film laminating machine based on the embodiment of the present application is clarified, which provides advantages such as the cutter wheel being placed in the knife seat under normal conditions, the cutter wheel extending out of the knife seat during work, and avoiding the cutter wheel from scratching the operator for the protection structure of the film cutting knife of the film laminating machine.

[0038] It is worth mentioning that in the embodiment of the present application, the protective structure of the film cutting knife of the film laminating machine has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economy. At the same time, for manufacturers, the protective structure of the film cutting knife provided by the present application is easy to produce and has a low cost, which is more conducive to controlling production costs and further conducive to the promotion and use of products.

The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention can have any deformation or modification without departing from the principle.
