Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a high-efficiency protective film laminating device. Background Art

[0002] High-efficiency protective film laminating equipment is an important equipment widely used in modern industrial production. It is mainly used to accurately and quickly apply protective film to the surface of various products to protect the products. Its working principle is mainly to pull the protective film from the roll through a mechanical device and accurately cover the surface of the product, and then use pressure to firmly adhere the protective film to the product.

[0003] During the protective film lamination process, a certain amount of pressure needs to be applied to the protective film to ensure that the protective film can fit tightly and smoothly on the product surface. However, different products may have different shapes, sizes and surface characteristics, which requires the pressure roller to automatically adjust the pressure according to the specific conditions of the product. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the background technology and to propose a high-efficiency protective film laminating device.

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

[0006] A high-efficiency protective film laminating device includes a frame, the top of the frame is fixedly connected to two fixed frames, the tops of the two fixed frames are penetrated by and slidably connected to a sliding rod, the bottom of the sliding rod is fixedly connected to a fixed block, the top of the fixed block is installed with a return spring, the fixed block is penetrated by and rotatably connected to a third rotating shaft, and a second roller is sleeved on the third rotating shaft.

[0007] Preferably, the frame is penetrated by and rotatably connected to two first rotating shafts, and conveyor belts are sleeved on the two first rotating shafts.

[0008] Preferably, a motor is fixedly mounted on the side wall of the frame via a fixing seat, and an output end of the motor is fixedly connected to the first rotating shaft.

[0009] Preferably, two first support rods are fixedly connected to the top of the frame, and the upper ends of the two first support rods pass through and are rotatably connected to a second rotating shaft, and a first roller is sleeved on the second rotating shaft.

[0010] Preferably, two second support rods are fixedly connected to the top of the frame, and the upper ends of the two second support rods pass through and are rotatably connected to a rotating rod.

[0011] Preferably, a metal frame is welded to the top of the rack, and a heating plate is fixedly mounted on the inner wall of the metal frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model provides a fixed frame, a sliding rod, a fixed block, a return spring, a third rotating shaft and a second roller, so that the second roller can always maintain uniform pressure on the protective film and the surface of the laminated product during the laminating process. Regardless of whether there are slight unevenness on the surface of the product or a certain change in the product size, the return spring can automatically adjust the position of the second roller to ensure that the laminating pressure is consistent everywhere, thereby effectively avoiding local loose lamination or defects such as bubbles and wrinkles, and greatly improving the flatness and firmness of the protective film lamination.

[0014] 2. The utility model is able to increase the temperature between the protective film and the laminated product by setting a heating plate, so that the activity of the adhesive or glue layer is enhanced at a certain temperature, thereby improving the adhesion between the two. During the lamination process, heating can make it easier to discharge the air on the surface of the protective film and the product, reducing the generation of bubbles.

DETAILED DESCRIPTION

[0019] 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.

[0020] Reference Figure 1-3A highly efficient protective film laminating device includes a frame 1 having a rectangular shape and an opening in the middle. Two symmetrical fixed frames 10 are fixedly connected to the top of the frame 1. A slide bar 11 is passed through the tops of the two fixed frames 10 and is slidably connected thereto. A fixed block 13 is fixedly connected to the bottom of the slide bar 11. A return spring 12 is mounted on the top of the fixed block 13 and is fixedly connected to the inner wall of the top of the fixed block 13. A third rotating shaft 14 is passed through the two fixed blocks 13 and is rotatably connected thereto. A second roller 15 is sleeved on the third rotating shaft 14.

[0021] The frame 1 passes through and is rotatably connected to two first rotating shafts 2, on which a conveyor belt 3 is sleeved, and a motor 4 is fixedly mounted on the side wall of the frame 1 through a fixed seat, and the output end of the motor 4 is fixedly connected to the first rotating shaft 2. The top of the frame 1 is fixedly connected to two first support rods 5, and the upper ends of the two first support rods 5 pass through and are rotatably connected to a second rotating shaft 6, and a first roller 7 is fixedly sleeved on the second rotating shaft 6;

[0022] A second support rod 8 is fixedly connected to the top of the frame 1, and the upper end of the second support rod 8 passes through and is rotatably connected to a rotating rod 9. A metal frame 16 is welded to the top of the frame 1, and heating plates 17 are fixedly installed on the inner walls on both sides of the upper end of the metal frame 16.

[0023] The detailed working process of this utility model is as follows:

[0024] First, place the protective film on the first roller 7, then pass the end of the protective film under the rotating rod 9, then manually lift the second roller 15, and then place the end of the protective film in the gap between the second roller 15 and the conveyor belt 3, and loosen the second roller 15.

[0025] Then place the product that needs to be fitted with a protective film on the conveyor belt 3, start the motor 4 to drive the first rotating shaft 2 to rotate, and the conveyor belt 3 rotates, and the rotation of the conveyor belt 3 drives the product to move toward the heating plate 17. When passing through the second roller 15, the slide bar 11 slides up and down, and the second roller 15 is squeezed to lift the second roller 15. At the same time, the second roller 15 is against the top of the product. As the product moves, the second roller 15 squeezes the protective film to fit the protective film to the top of the product, and then the heating plate 17 is started for heating.

[0026] 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.
