Detailed ways

The following are specific embodiments of the present invention combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, and Fig. 7, an automatic film splicing mechanism includes: a mounting frame 100, a first film supply unit, a second film supply unit, and a second film supply unit. All film unit 400 and bonding unit 600, the automatic film splicing structure can realize the effect of automatic film splicing. It can be used in all production lines that cannot stop the film to complete the automatic docking between two rolls of film, so the application is very Extensively, for example, the automatic film splicing mechanism can be used in a double bond production line.

In the existing repress production line, there are many products that need to be pasted with a layer of appearance film. The film has two layers of protective film and a layer of black and bright film (attached to the product). During the production process, the length of a roll of film Limited. After use, the film must be worn again and the production line cannot be stopped during this process. The film connection takes at least 5 minutes to complete. During this period, all the products processed on the production line will be scrapped, and the waste will be large; It has to start again, resulting in more product scraps. In addition, re-penetrating the film has a large impact on human factors, and product quality problems after the second film-penetrating may cause a lot of waste.

The length of one roll of film is limited, and two rolls of film must be exchanged. Manual roll change will cause waste and poor product quality. In order to solve similar problems, it is necessary to connect two rolls of film. The mechanism only needs to be advanced in advance. Just place the tape and adhesive film. When one roll of film is used up, the mechanism can connect another roll of film to this roll of film and continue the filming action.

The mounting frame 100 is fixedly arranged, and the first film supply unit, the second film supply unit, the first film unit 400 and the bonding unit 600 are all arranged on the mounting frame 100.

The mounting frame 100 can be a plate structure, a bracket structure or other structures. In a specific structure, the mounting frame 100 includes a mounting panel and a mounting bracket. The mounting panel is fixed on the two vertical support arms of the mounting bracket. The first film supply The unit and the second film supply unit can be arranged on the installation panel of the mounting frame 100, and are respectively located on the left and right sides of the installation panel, and the first film unit 400 can be located in the mounting bracket, so that the first film supply unit is located on the first Everything above the membrane unit 400.

The first film supply unit includes a first film roll 210 for storing the main film body 211. Preferably, the first film supply unit is used for storing the main film body 211 and releasing the main film body 211, wherein the first film roll 210 is the structure formed by the main film body 211 wound on the ring body, which stores the main film body 211, and when in use, the main film body 211 can be pulled out from the first film roll 210.

The second film supply unit is arranged on the mounting rack 100. The second film supply unit includes a second film roll 310 for storing a spare film body 311. Preferably, the structure of the second film roll 310 is similar to that of the second film roll 310. A film roll 210 is similar, the spare film body 311 can be pulled out from the second film roll 310. Under normal circumstances, the spare film body 311 will not be used, only when the main film body 211 on the first film roll 210 is used up. After that, the spare film body 311 will be connected.

The first cut film unit 400 is connected to the mounting frame 100, and the first cut film unit 400 is used to cut the main film body 211 on the first film roll 210; preferably, the first cut film unit 400 is actually movably arranged on the mounting frame 100, and the first film unit 400 can be located above or below the first film roll 210, in short, it can correspond to the first film roll 210, and the first film roll After the main film body 211 on the 210 is pulled out, it passes through the first cut film unit 400, so that the first cut film unit 400 can cut the main film body 211 when the first film roll 210 is used up. After the main film body 211 is cut One part is connected with the first film roll 210, and the other part of the main film body 211 is separated from the first film roll 210 and can be bonded with the spare film body 311.

The bonding unit 600 is used to bond the spare film body 311 on the second film roll 310 to the cut main film body 211; preferably, the bonding unit 600 can be separately connected to the mounting frame 100 It can also be connected to the first film unit 400. In short, the bonding unit 600 can bond the main film body 211 and the spare film body 311 together.

In the actual working process, the first film roll 210 supplies the main film body 211. When the first film roll 210 is used up, since the main film body 211 and the first film roll 210 are connected together, the main film body 211 is now It cannot be bonded with the spare film body 311, so the first film unit 400 is required to cut the main film body 211, so that the main film body 211 is separated from the first film roll 210, and the rear end of the main film body 211 after separation It is glued together with the front end of the spare film body 311 on the second film roll 310, which can efficiently complete the butt joint between the two rolls of film, and can ensure that after the film is connected, the butted film has little effect on the product quality, and has a great The saved production cost and improved product quality have greatly improved the subsequent filming process.

Specifically, the first sliding seat 450 can slide back and forth, that is, the first sliding seat 450 can approach the mounting frame 100 or move away from the mounting frame 100, so that the first clamping assembly and the first cutting assembly can be close to the main membrane body. 211 or away from the main film body 211; after the main film body 211 and the spare film body 311 are bonded, since a part of the main film body 211 is located in the first clamping assembly, the bonded film body cannot be connected to the first clamping assembly. The separation hinders the normal use of the membrane body. The first cutting assembly and the first clamping assembly are driven to move by the first sliding seat 450 to solve the above problem. In the actual work process, when the main membrane body 211 needs to be cut, the first A sliding seat 450 moves forward so that the first clamping assembly and the first cutting assembly reach the set position. At this time, the main membrane body 211 is located within the range of the first cutting assembly and the first clamping assembly.
