DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0019] As Figure 1 shown, in this embodiment, the film back gluing device includes a large bottom plate 1, on which a plastic film roll group 4 with plastic film rolls wound thereon is arranged. A glue application valve unit 5 is arranged in the film outlet direction of the plastic film roll group 4. An upper pressing plate 11 is driven by an upper pressing plate cylinder 10 on the large bottom plate 1, and a vacuum suction unit plate 16 driven by a lower pressing plate cylinder 15 is arranged directly below the upper pressing plate 11. The vacuum suction unit plate 16 is a prior art. A film pulling operation belt 13 is connected below the large bottom plate 1, and a film pulling jaw unit 14 that is linked with the film pulling operation belt 13 and runs above the working area of the vacuum suction unit plate 16.

[0020] The large bottom plate 1 is in the shape of a long plate, and a notch is provided on one side of its long side end. The notch is used to avoid the adhesion of the plastic film and the film sheet. The large bottom plate 1 is connected to the support elevated plate 2 through a vertical plate standing on its upper surface. The support elevated plate 2 is opposite to the notch at the long side end of the large bottom plate 1. The upper pressure plate cylinder 10 is connected to the lower surface of the support elevated plate 2 and its output end is set downward.

[0021] The plastic film roll group 4 is installed on the connecting frame 3 located at the short side end of the large bottom plate 1. The glue application valve unit 5 is installed on the vertical plate of the support elevated plate 2 near the plastic film roll group 4. The horizontal height of the plastic film roll group 4 is higher than that of the glue application valve unit 5. The plastic film roll in the plastic film roll group 4 is installed in the middle through two acrylic sheets. A number of roller wheels for tensioning the plastic film output from the plastic film roll are provided on the connecting frame 3.

[0022] The adjacent jaw cylinder 6 and the extending cylinder 7 are connected to the lower side of the large bottom plate 1 near the glue application valve unit 5. The extending cylinder 7 is located at the rear side end of the plastic film tensioning and discharging. The extending cylinder 7 drives a pair of scissors 8. The scissors 8 and the jaws of the jaw cylinder 6 are at the same horizontal height.

[0023] Preferably, the scissors 8 extend towards the vacuum suction unit plate 16 and are located at the end position of this end of the vacuum suction unit plate 16. This is beneficial to the accurate cutting of the plastic film.

[0024] A plastic film guiding shaft 9 extending towards the vacuum suction unit plate 16 is connected to the jaws of the jaw cylinder 6. The plastic film guiding shaft 9 is implemented in a way that guides the plastic film roll to enter the working area of the vacuum suction unit plate 16. It should be noted that the plastic film guiding shaft 9 is not within the working area of the vacuum suction unit plate 16.

[0025] A film pulling operation motor 12 for driving the film pulling operation belt 13 is installed at the short side end of the large bottom plate 1 away from the plastic film roll group 4. The driving connection between the film pulling operation belt 13 and the film pulling operation motor 12 is prior art, so it is not shown in the figure.

[0026] Preferably, the film pulling operation belt 13 is arranged in the same direction as the long side end of the large bottom plate 1. The film pulling operation belt 13 is specifically installed at a position close to the notch at the long side end of the large bottom plate 1. On this basis, the film pulling jaw unit 14 is implemented in a way that pulls the plastic film roll from one end to the other end of the vacuum suction unit plate 16. That is to say, the moving track of the film pulling operation belt 13 driving the film pulling jaw unit 14 covers the entire working area of the vacuum suction unit plate 16.

[0027] A waste cup 17 is also provided beside the glue application port of the glue application valve unit 5.

[0028] The working principle of this embodiment is as follows:

[0029] The plastic film roll in the plastic film roll group 4 is guided by the plastic film guiding shaft 9 and is pressed by the upper pressing block of the film pulling jaw unit 14 that runs to one end side of the plastic film guiding shaft 9 under the linkage of the film pulling running belt 13. Then, the film pulling running motor 12 works to drive the film pulling running belt 13 to transmit, and the film pulling jaw unit 14 pulls out the plastic film. During this process, the glue application valve unit 5 starts to apply glue;

[0030] When the film pulling jaw unit 14 runs to the end point, that is, the other end of the vacuum suction unit plate 16, the glue application work ends;

[0031] Next, the vacuum suction unit plate 16 starts to evacuate, the jaw cylinder 6 clamps the plastic film, and the scissors 8 cut the plastic film under the drive of the extending cylinder 7;

[0032] Next, the film pulling jaw unit 14 releases the plastic film, the lower pressing plate cylinder 15 acts to drive the vacuum suction unit plate 16 to rise. At the same time, the upper pressing plate cylinder 10 drives the upper pressing plate 11 to descend to bond the glue-coated plastic film to the back of the film piece. After the bonding is completed, the operation is completed.

[0033] In addition, every once in a while, the glue application valve unit 5 needs to spit out glue, and it will spit out cyclically within the time period. In order to prevent the glue in the valve pipe from curing, the waste glue will be spit into the waste cup 17.

[0034] This application discloses a device for applying glue to the back of a film piece, which solves the problem of applying glue to the back of the film piece, protects the glue applied to the back of the film piece from sticking to other components during operation, and at the same time eliminates the method of using adhesive tapes. Through glue bonding, the viscosity is greatly enhanced and it is not easy to fall off.

[0035] The above embodiments are not limitations on the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the technical scope of the present invention also fall within the protection scope of the present invention.
