Description

Technical Field

[0001] The utility model relates to the technical field of laminating devices, in particular to a precise laminating device for plastic packaging films. Background Art

[0002] In the packaging industry, packaging materials have also achieved rapid development, but also have undergone severe challenges. The film-laminating device of the packaging material can bond the plastic or cover one layer (base material) with a layer of plastic film.

[0003] In the prior art, laminating rollers are typically used to precisely adhere plastic packaging film to the outer wall of a substrate. However, during the production and transportation of substrates (such as plastics and cardboard), friction generates static electricity, which accumulates on the surface of the substrate, forming an electrostatic field. This electrostatic field attracts dust particles in the air, contaminating the surface of the substrate. During the subsequent lamination process, these dust particles hinder the close fit between the film and the substrate, easily causing defects such as localized loosening, blistering, and wrinkling, thereby affecting the overall quality and aesthetics of the packaging. Therefore, it is necessary to propose a device for precisely laminating plastic packaging film to address these issues. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a precise laminating device for plastic packaging films.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Preferably, the outer wall of the mounting frame is fixedly connected to a limit rod, and the lead screw sleeve is slidably connected to the outer wall of the limit rod.

[0008] Preferably, two groups of limit blocks are fixedly connected to the outer wall of the reciprocating screw, and the radius of the two groups of limit blocks is larger than the radius of the reciprocating screw.

[0009] Preferably, an electric telescopic rod is fixedly connected to the outer wall of the mounting frame, and a pressure plate is fixedly connected to the telescopic end of the electric telescopic rod, and there is a certain small gap between the pressure plate and the device roller 2.

The two sets of transmission wheels are connected to each other through transmission belts, and the two sets of transmission wheels are coaxially fixedly connected to their adjacent device rollers and reciprocating screws.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model drives the cleaning brush to slide horizontally through a reciprocating screw, so that the cleaning brush can remove dust particles adsorbed by static electricity back and forth along the surface of the base material, thereby preventing dust particles from hindering the close fitting of the plastic film and the base material during the laminating process, and significantly reducing defects such as bubbles, looseness or wrinkles caused by dust during the laminating process, ensuring the overall flatness and aesthetics of the laminating effect, and improving the quality of packaging.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 , a precise bonding device for plastic packaging film includes a mounting frame 1, the outer wall of the mounting frame 1 is rotatably connected with a discharge roller 2, a receiving roller 3, two sets of laminating rollers 4, a device roller 1 5 and a device roller 2 6, the discharge roller 2 and the receiving roller 3 are respectively located at both ends of the mounting frame 1, the device roller 1 5 and the device roller 2 6 are located on the same horizontal plane, the outer wall of the mounting frame 1 is rotatably connected with a reciprocating screw 11, the threaded section of the reciprocating screw 11 is threadedly connected with a screw sleeve 14, the outer wall of the screw sleeve 14 is fixedly connected with a cleaning brush 15, and there is a certain gap between the cleaning brush 15 and the device roller 1 5; the cleaning brush 15 slides to effectively remove dust particles on the surface of the base material, and cleans it before laminating to ensure the overall quality and aesthetics after bonding.

[0023] The outer wall of the mounting frame 1 is fixedly connected to a limit rod 13, the screw sleeve 14 is slidably connected to the outer wall of the limit rod 13, and the outer wall of the reciprocating screw 11 is fixedly connected to two groups of limit blocks 12, and the radius dimensions of the two groups of limit blocks 12 are both larger than the radius dimension of the reciprocating screw 11.

[0024] The outer wall of the mounting frame 1 is fixedly connected to an electric telescopic rod 16, and the telescopic end of the electric telescopic rod 16 is fixedly connected to a pressure plate 17. There is a certain small gap between the pressure plate 17 and the device roller 2 6. The outer wall of the mounting frame 1 is rotatably connected to two sets of transmission wheels 8, and the sizes of the two sets of transmission wheels 8 are inconsistent. The two sets of transmission wheels 8 are connected to each other through a transmission belt 9. The two sets of transmission wheels 8 are respectively coaxially fixedly connected to their adjacent device roller 1 5 and the reciprocating screw 11; the set pressure plate 17 can press the base material after the film is laminated, so as to improve the bonding effect.

[0025] Multiple motor groups 1 7 and a single motor group 2 10 are fixedly connected to the outer wall of the mounting frame 1. The multiple motor groups 1 7 are coaxially fixedly connected to the adjacent unwinding roller 2, the receiving roller 3 and the laminating roller 4, respectively. The motor 2 10 is coaxially fixedly connected to the adjacent transmission wheel 8. It should be noted that the roller body with the plastic packaging film curled up is installed on the outside of the mounting frame 1, so that when the packaging film roll needs to be replaced, there is no need to enter the inside of the device, and the operation is more convenient.

[0026] In the present invention, when the device is used specifically: start motor 1 7, drive the discharge roller 2 to gradually send the base material out from the discharge end. As the base material moves, the motor 2 10 drives the device roller 1 5 and the transmission wheel 8 to rotate, and the reciprocating screw 11 drives the cleaning brush 15 to slide horizontally, sliding back and forth along the surface of the base material to remove surface dust particles. After cleaning, the dust on the surface of the base material is effectively removed, providing a clean surface for subsequent lamination, avoiding bubbles, looseness or wrinkles caused by dust.

[0027] The cleaned base material enters the laminating area. First, the motor 7 drives the laminating roller 4 to operate, pulling the outer plastic packaging film from the roller body and evenly sticking it to the surface of the base material. The rolling of the laminating roller 4 ensures that the plastic film is flatly stuck to the base material, and the lamination of the two is initially achieved.

[0028] After the base material and the coating pass through the device roller 2 6, the electric telescopic rod 16 drives the pressing plate 17 to press down, forming a certain pressing effect between the device roller 2 6 to ensure that the surface after bonding is smooth without bubbles or wrinkles. The base material with the coating is wound up by the receiving roller 3 driven by the motor 1 7, completing the entire bonding process.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
