[0018] The following will describe in detail two implementation manners of the present application with reference to the accompanying drawings.
[0019] The first implementation manner: Figures 1 - 7 And Figure 12 Shown is a film laminating device for producing self-adhesive labels, including a machine body 1. A feeding paper roll 2 and an oiling device 17 are respectively rotatably connected to both ends of the machine body 1. A paper material 3 is wound on the feeding paper roll 2. The paper material 3 is composed of a base paper 301 and a face paper 302. Inside the machine body 1, a first cutting roller 4, a first waste roller 5, a feeding film roll 6, a pressing roller 8, a second cutting roller 9, a second waste roller 11 and a hemming device 12 are sequentially installed from left to right. The paper material 3 passes through the first cutting roller 4, the pressing roller 8, the second cutting roller 9, and the hemming device 12 in sequence to complete the processing and is finally wound on a finished product roll 7. When the paper material 3 passes through the first cutting roller 4, the face paper 302 is cut and divided into a label 3021 and waste paper 3022. The first waste roller 5 is used for winding the waste paper 3022. A film 10 is wound on the feeding film roll 6. When the paper material 3 passes through the pressing roller 8, it is adhered to the film 10. The second cutting roller 9 is used for cutting the film 10, and after the film 10 is cut, it is divided into a label film 1001 and a waste film 1002. The label film 1001 covers the label 3021, and the part of the label film 1001 that extends beyond the label 3021 is set as a border film 1003. The second waste roller 11 is used for winding the waste film 1002. When the paper material 3 passes through the hemming device 12, the border film 1003 is squeezed and adhered to the side wall of the label 3021; The above settings can play a role in sealing the edge of the label 3021, improve the sealing performance of the label 3021, and increase the waterproof, moisture-proof effect and service life of the label 3021.
[0020] The hemming device 12 includes a mounting plate 1201 fixedly connected to the machine body 1. A sliding frame 1202 is fixedly connected to the bottom end of the mounting plate 1201. A lifting box 1203 is slidably connected inside the sliding frame 1202. An intermediate plate 1204 is arranged inside the lifting box 1203. A plurality of support rods 1205 are fixedly connected to the bottom end of the intermediate plate 1204. The support rods 1205 penetrate and are slidably connected to the bottom end of the lifting box 1203. The hemming device 12 further includes a bottom plate 1209 fixedly connected to the inner wall of the machine body 1. A plurality of top springs 1206 are fixedly connected between the top end of the intermediate plate 1204 and the inner wall of the top end of the lifting box 1203. An air lifting rod 1210 is fixedly connected to the middle of the mounting plate 1201. The output end of the air lifting rod 1210 is fixedly connected to the top end of the lifting box 1203. A combined plate 1207 is fixedly connected between the bottom ends of the plurality of support rods 1205. A plurality of buckle rings 1208 matching the label 3021 and the border film 1003 are fixedly connected to the bottom end of the combined plate 1207.
[0021] The stock 3 and the film 10 are located between the buckle 1208 and the bottom plate 1209. When the edging device 12 works, the pneumatic lifting rod 1210 starts to drive the lifting box 1203 to move up and down reciprocally. When the lifting box 1203 moves downward, it drives the buckle 1208 to move downward, so that the buckle 1208 covers the edge of the surrounding film 1003 and generates extrusion, making the surrounding film 1003 adhere to the label 3021.
[0022] The second embodiment: Figures 8 - 13 A film laminating device for producing self-adhesive labels is shown. Different from the first embodiment, a third cutting roller 13 is installed inside the machine body 1. The third cutting roller 13 is located between the first waste roller 5 and the feeding film roller 6. An adhesive layer 15 is provided at the bottom end of the face paper 302. When passing through the third cutting roller 13, the adhesive layer 15 is cut and divided into the bottom glue 1501 and the waste glue 1502. The part of the bottom glue 1501 that exceeds the label 3021 matches the surrounding film 1003. A third waste roller 16 is installed inside the machine body 1 and the third waste roller 16 is located between the third cutting roller 13 and the feeding film roller 6. The third waste roller 16 is used to wind up the waste glue 1502.
[0023] In the first embodiment, the waste film 1002 is directly bonded to the side surface of the label 3021, which can wrap the label 3021 to form a complete seal. However, when the waste film 1002 wraps the label 3021, its end is parallel to the bottom surface of the label 3021. At this time, when the label 3021 is adhered, the waste film 1002 does not have adhesiveness, which causes the end of the waste film 1002 to be prone to water ingress during use, and the adhesion ability between the waste film 1002 and the label 3021 is not strong enough, making it easy to curl.
[0024] When cutting the adhesive layer 15, make the bottom glue 1501 exceed part of the label 3021. In this way, when the label film 1001 wraps the label 3021, the end of the surrounding film 1003 can be bonded to the bottom glue 1501, completing the seal of the end of the label film 1001, preventing the label film 1001 from curling, and improving the bonding effect of the self-adhesive label.
[0025] In this embodiment, it is applicable to self-adhesive labels where the face paper 302 and the adhesive layer 15 are easy to peel off. For example, there is no adhesion between the adhesive layer 15 and the base paper 301 because a release layer is provided on the surface of the base paper 301. At this time, a release layer can also be provided on the bottom surface of the face paper 302. When the face paper 302 is cut by the first cutting roller 4, the waste paper 3022 can be better separated from the adhesive layer 15.
[0026] When a release layer is provided on the bottom surface of the face paper 302, the label 3021 is easy to separate from the adhesive layer 15 during use. With the above settings, a complete sealing layer can be formed between the film 10 and the bottom glue 1501, which can prevent the label 3021 from separating outward.
[0027] An oiler 17 is installed inside the machine body 1. The oiler 17 includes three rollers 1701 rotatably connected to the machine body 1. An oil conveyor belt 1702 is rotatably connected between the three rollers 1701. One end of the oil conveyor belt 1702 is in contact with the surface of the third cutting roller 13. The oiler 17 further includes an oil tank 1703 fixedly connected to the machine body 1. A cotton block 1704 is fixedly connected to the bottom end of the oil tank 1703. The bottom end of the cotton block 1704 is in contact with the oil conveyor belt 1702. An oil spray head 14 is fixedly connected to the top end of the oil tank 1703.
[0028] With the above arrangement, the oil spray head 14 sprays release oil onto the surface of the cotton block 1704. The release oil is evenly applied to the surface of the oil conveyor belt 1702 through the cotton block 1704. When the oil conveyor belt 1702 rotates, the release oil can adhere to the surface of the third cutting roller 13, enabling the third cutting roller 13 to better separate from the adhesive layer 15 during cutting to prevent adhesion.
[0029] Release oil (also known as release agent) is a special chemical material used to prevent adhesion in industrial production. Its core function is to form a low surface energy coating on the surface of the mold or substrate, making it easy for the formed part or the adhered object to detach.
[0030] Combined with the current actual requirements, the above implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
