The plastic film and the cardboard are bonded together through heating and pressing to protect the patterns. And in order to facilitate the bonding of the cardboard after folding to form a carton, generally a plasma gun is used to corona-treat the plastic film, oxidize and polarize the molecules on the surface of the cardboard film laminating, so that the ions of the plasma gun shock and erode the surface of the cardboard film laminating, thereby adjusting the tension of the film laminating and increasing the adhesion ability of the carton film laminating. When corona-treating the cardboard film laminating, due to the different specifications and sizes of the cardboard and the different bonding ranges required, and the limited corona range of the plasma gun, the corona range of the plasma gun is relatively thick or relatively thin, resulting in poor quality of the corona treatment of the cardboard film laminating.

[0020] 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.

[0021] The present utility model provides a technical solution: As Figures 1 to 4 shown, in this embodiment, a cardboard film laminating tension adjusting device includes a cylinder 1. A plasma gun body 4 is fixedly connected to the side wall of the cylinder 1. One end of the plasma gun body 4 is provided with a gun head 5. The telescopic rod of the cylinder 1 and the gun head 5 are on the same side of the plasma gun body 4. The end of the telescopic rod of the cylinder 1 is fixedly connected to a mounting post 2. The other end of the mounting post 2 is rotatably connected to a rotating disk 3. A plurality of mounting holes 8 are formed in the rotating disk 3. Nozzles 6 adapted to the gun head 5 are respectively arranged in the plurality of mounting holes 8. The nozzle diameters of the plurality of nozzles 6 are all different. A positioning mechanism acting on the rotating disk 3 is arranged at one end of the rotating disk 3 close to the cylinder 1.

[0022] Among them, the positioning mechanism is composed of a positioning groove 9, a positioning roller 12 and a clamping component acting on the positioning roller 12. Positioning grooves 9 are respectively formed in the side wall of the rotating disk 3 close to the cylinder 1 at the central positions between the mounting post 2 and the plurality of mounting holes 8. The inner wall of the positioning groove 9 is an arc surface and is mutually adapted to the outer surface of the positioning roller 12. A clamping component acting on the positioning roller 12 is arranged on the mounting post 2. The clamping component is composed of a fixed horizontal plate 10, a U-shaped plate 11, a guide rod 13 and a spring 14. The fixed horizontal plate 10 is fixedly connected to the side wall of the mounting post 2. The fixed horizontal plate 10 is parallel to the rotating disk 3. Two guide rods 13 penetrate through the fixed horizontal plate 10 in a sliding manner. Limit blocks 15 are respectively fixedly connected to the ends of the two guide rods 13 far away from the rotating disk 3. A U-shaped plate 11 is fixedly connected to the ends of the two guide rods 13 close to the rotating disk 3. A positioning roller 12 is rotatably connected between the two parallel plates of the U-shaped plate 11. A spring 14 is wound around the outer surface of the guide rod 13. The two ends of the spring 14 are respectively fixedly connected to the fixed horizontal plate 10 and the U-shaped plate 11.

[0023] The spring 14 is always in a compressed state. Under the extrusion of the spring 14, the positioning roller 12 will always press against the bottom of the rotating disk 3. When the rotating disk 3 is rotated to replace the nozzle 6 with a different size, the positioning roller 12 will roll on the bottom of the rotating disk 3. Whenever the positioning roller 12 rolls into a positioning groove 9, the gun head 5 will be aligned with a nozzle 6, thus quickly completing the alignment of the gun head 5 and the nozzle 6 to be replaced, effectively improving the work efficiency. It should be noted that since the inner wall of the positioning groove 9 is an arc surface and is mutually adapted to the outer surface of the positioning roller 12, after the positioning roller 12 rolls into the positioning groove 9, without being interfered by external forces, the positioning roller 12 will not shake randomly, ensuring the stability of the positioning. And when the rotating disk 3 is rotated forcefully, the positioning roller 12 can roll out of the positioning groove 9 without affecting the rotation of the rotating disk 3.

[0024] Among them, the multiple mounting holes 8 are arranged in a circular array centered on the axis of the rotating disk 3, and the distance between the mounting hole 8 and the axis of the rotating disk 3 is equal to the distance between the gun head 5 and the axis of the rotating disk 3.

[0025] With such a setting, the gun head 5 will be aligned with the nozzle 6 in the mounting hole 8.

[0026] Among them, an external thread 7 is provided on the outer wall of the bottom of the nozzle 6, and an internal thread that is in threaded cooperation with the external thread 7 is provided on the inner wall of the mounting hole 8.

[0027] The nozzle 6 can be threadedly connected to the internal thread on the inner wall of the mounting hole 8 through the external thread 7.

[0028] The utility model provides a cardboard film laminating tension adjusting device, and the specific working principle is as follows:

[0029] During use, when it is necessary to replace the nozzle 6 with different nozzle diameters, control the telescopic rod of the cylinder 1 to extend, so that the rotating disk 3 is separated from the gun head 5, and then rotate the rotating disk 3 to align the nozzle 6 to be installed on the rotating disk 3 with the gun head 5, and then control the telescopic rod of the cylinder 1 to contract, so that the gun head 5 is inserted into the nozzle 6 to be installed, and the replacement of the nozzle 6 with different nozzle diameters can be completed, making the range of the ionized spark ejected by the gun head 5 adjustable, so as to facilitate the corona treatment of cardboard with different corona ranges. In this process, the nozzle 6 and the gun head 5 can be quickly aligned through the provided positioning mechanism;

[0030] Specifically, the spring 14 is always in a compressed state. Under the extrusion of the spring 14, the positioning roller 12 will always press against the bottom of the rotating disk 3. When the rotating disk 3 is rotated to replace the nozzle 6 with a different size, the positioning roller 12 will roll on the bottom of the rotating disk 3. Whenever the positioning roller 12 rolls into a positioning groove 9, the gun head 5 will be aligned with a nozzle 6. Continuously rotate the rotating disk 3 until the gun head 5 is aligned with the nozzle 6 to be installed, and the alignment of the gun head 5 and the nozzle 6 to be replaced can be quickly completed, which can effectively improve work efficiency. It should be noted that since the inner wall of the positioning groove 9 is an arc surface and is adapted to the outer surface of the positioning roller 12, after the positioning roller 12 rolls into the positioning groove 9, without being interfered by external forces, the positioning roller 12 will not shake randomly, ensuring the stability of positioning. Moreover, when the rotating disk 3 is rotated forcefully, the positioning roller 12 can roll out of the positioning groove 9, avoiding the situation where the rotating disk 3 is stuck.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
