[0002] As an indispensable part of modern logistics, color boxes bear the important responsibilities of containing, protecting products and beautifying. They are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. When color boxes are produced, they are made of ordinary corrugated paper, by laminating colored films on the surface, and then cutting and packaging. When the color film is pasted on the surface of the color box, it needs to be assisted by the laminating component, but the laminating component still has the following disadvantages in actual use:

[0003] When the laminating component of the color film on the color box surface is laminating, it directly passes through the pressing roller to contact the color film with the cardboard. Since the carton is made of cardboard, the surface is not flat enough, which makes it easy for bubbles to form on the surface of the color film, causing laminating defects;

[0004] When the laminating components of the colored film on the surface of the color box are being laminating, a large amount of dust will remain on the storage space of the cardboard due to the paper quality. When laminating, the dust will be directly adhered to the space between the colored film and the cardboard, causing the colored film to not adhere tightly enough to the cardboard, which can easily cause the colored film to fall off.

[0024] See also Figure 1-5 As shown, the utility model is a bubble-removing and laminating component for a color film on the surface of a color box, comprising a pressing roller 1, a transmission shaft 2, a support plate 3 and a connecting pipe 4. The pressing roller 1 is fixed with a transmission shaft 2 running through it. The pressing roller 1 is used to guide the color film to a suitable film-laminating position on the surface of the paperboard. The power of an external driving device is transmitted to the pressing roller 1 through the transmission shaft 2 to drive the pressing roller 1 to rotate. The peripheral sides of the transmission shaft 2 on the outer sides of both ends of the pressing roller 1 are movably connected with support plates 3. The bottom of the support plate 3 is fixed to an external supporting structure to support the transmission shaft 2 on the supporting structure. The two support plates 3 are symmetrical to each other. A fixing plate 401 is fixed on one side of the two support plates 3. The fixing plate 401 is used to fix the connecting pipe 4 and the support plate 3 to connect the connecting pipe 4 to the support plate 3. A connecting pipe 4 is fixed to the two fixing plates 401. The connecting pipe 4 is used to transfer the high pressure conveyed in the air intake pipe 402. The connecting tube 4 is provided with a plurality of air outlet pipes 403 which are fixedly connected at equal intervals and tilted downward on the circumference of the connecting tube 4. The air outlet pipes 403 convey the high-pressure air transferred in the connecting tube 4 to the jet shell 404. The pressing roller 1 comprises a connecting disk 101 and a flexible outer roller 104. The flexible outer roller 104 is fixedly fixed at the end edge between the two connecting disks 101. The flexible outer roller 104 expands when inflated, and the side of the color film without adhesive is attached thereto. When the film is attached to the surface of the cardboard, the flexible outer roller 104 rotates, and the film is attached to the unprinted position of the cardboard, so that the color film is attached to the surface of the cardboard. Since the flexible outer roller 104 is flexible, the color film of the color box can be well attached to the surface of the cardboard, reducing the generation of bubbles on the surface of the cardboard. The transmission shaft 2 is fixed through the two connecting disks 101, and the central axis of the transmission shaft 2 coincides with the central axis of the connecting disk 101.

The air holes 103 are arranged in a circular array in the middle of the circumference of the inner roller 102. The pressure roller 1 connects the two connecting disks 101 stably together through the inner roller 102, and the inner roller 102 allows the gas filled by the air nozzle 105 to pass between the inner roller 102 and the flexible outer roller 104 through the air holes 103 on the circumference of the inner roller 102, so that the flexible outer roller 104 is inflated.

[0026] Among them Figure 1 , 2As shown, the pressure roller 1 also includes an air nozzle 105 and a barometer 106. The barometer 106 is fixed through the connecting disk 101 on one side of the transmission shaft 2. The air nozzle 105 is fixed through a position symmetrical to the center of the barometer 106 in the connecting disk 101. When the flexible outer roller 104 needs to be inflated, the air nozzle 105 is connected to the external inflation pipe joint to allow high-pressure air to be filled into the flexible outer roller 104, and the air pressure in the flexible outer roller 104 during and after inflation is determined by the barometer 106.

[0027] Among them Figure 1 , 3 As shown in , 4, a limiting disk 201 is fixed on the side of the transmission shaft 2 on the side of the support plate 3 away from the pressure roller 1, and the two limiting disks 201 are respectively fitted with the two support plates 3, and mounting disks 202 are fixed on both ends of the transmission shaft 2. The position of the transmission shaft 2 on the two support plates 3 is limited by the limiting disks 201, and the transmission shaft 2 is respectively installed with the external driving device and the braking device through the mounting disks 202 at both ends.

[0028] Among them Figure 1 , 4 As shown, the upper part of the two support plates 3 close to the pressure roller 1 is fixed with an electric push rod 301, and the telescopic end of the electric push rod 301 is fixed with a limiting bar 302. The support plate 3 drives the limiting bar 302 to move through the electric push rod 301, and after moving to a suitable position on the flexible outer roller 104 through the limiting bar 302, it limits and guides the position of the color box film on the flexible outer roller 104.

[0029] Among them Figure 1 , 5 As shown, one end of several air outlet pipes 403 away from the connecting pipe 4 is fixedly connected to a jet shell 404, the opening of the jet shell 404 is arranged away from the pressure roller 1, one end of the connecting pipe 4 is fixedly connected to an air inlet pipe 402, and one end of the air inlet pipe 402 away from the connecting pipe 4 is connected to an external pipeline for conveying high-pressure air, and the jet shell 404 sprays the high-pressure air conveyed in the air outlet pipe 403 to the unprinted position of the color-printed carton, so as to blow away the dust on the unprinted position of the color-printed carton.

[0030] The specific working principle of the utility model is as follows: when working, first determine the air pressure that needs to be inflated in the flexible outer roller 104. When the flexible outer roller 104 needs to be inflated, the air nozzle 105 is connected to the external inflation pipe joint, so that high-pressure air is filled into the flexible outer roller 104, and the air pressure in the flexible outer roller 104 during and after the inflation is determined by the barometer 106 until the flexible outer roller 104 reaches a suitable air pressure and stops working. The electric push rod 301 on the support plate 3 drives the limiting bar 302 to move, and after the limiting bar 302 moves to a suitable position on the flexible outer roller 104, the position of the color box film guided to the flexible outer roller 104 is restricted. , the air is transported to the connecting pipe 4 through the air inlet pipe 402, and then transported to the jet shell 404 through the air outlet pipe 403 on the side of the connecting pipe 4. The jet shell 404 sprays the high-pressure air transported in the air outlet pipe 403 to the unprinted position of the color-printed carton, blows away the dust on the unprinted position of the color-printed carton, and prevents the dust from forming bubbles on the surface of the carton. The carton is transported under the conveying assembly to the bottom of the pressure roller 1. At this time, the equipment for conveying the color film is conveyed from the outside to the lower part of the peripheral side of the flexible outer roller 104 under the restriction of the restriction strip 302, and fits with the surface of the carton. The flexible outer roller 104 is inflated so that the flexible outer roller 104 fits well with each position of the surface of the carton.
