Description

Technical Field

[0001] This utility model relates to the field of food packaging bag processing technology, specifically to a rapid processing method for food packaging bags.

[0002] Combined equipment. Background Technology

[0003] In the food flexible packaging industry, substrates such as multilayer plastic films, aluminum foil, or metallized films often require dry lamination with adhesives to obtain high-barrier, high-strength packaging bags. Existing rapid lamination equipment typically consists of an unwinding unit, an adhesive coating unit, an oven, a laminating unit, and a rewinding unit connected in series. In actual operation, it has been found that roll-shaped substrates (PET, BOPA, PE, AL, etc.) are highly susceptible to the adhesion of environmental dust, paper scraps, fibers, and low-molecular-weight precipitates during slitting, storage, transportation, and workshop transfer. If these surface contaminants are not effectively removed, the dust becomes trapped between the adhesive layer and the substrate, forming localized areas without adhesive. After curing, this manifests as bubbles or white spots, severely reducing lamination strength and affecting the product's appearance.

[0004] Therefore, a rapid lamination device for food packaging bags is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a rapid lamination device for food packaging bags in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a rapid lamination device for food packaging bags, comprising a frame, an elastic pressure component provided in a through groove on the surface of the frame, and a pressure roller rotatably mounted on the elastic pressure component; several sets of equidistant conveying rollers rotatably inserted into the side walls of the frame; a first motor fixedly mounted on the surface of the frame, the output end of the first motor being fixedly connected to the conveying roller located directly below the pressure roller; an adhesive application component provided inside the frame; a dust removal component provided on the frame for cleaning surface impurities of the substrate; and two sets of electric heating wires fixedly mounted on the inner wall of the frame.

[0007] Furthermore, the two side walls of the frame are rotatably connected with a first limiting roller and a second limiting roller, and the surface of the frame is provided with a feeding groove, and the packaging bag substrate roll is rotatably placed in the feeding groove.

[0008] Furthermore, the elastic pressure application assembly includes a sleeve rod fixedly installed at the top of the through groove, and a rod body is movably inserted into the bottom end of the sleeve rod. A movable block is fixedly installed at the bottom end of the rod body, and the movable block slides vertically within the through groove. A spring is fixedly connected to the top surface of the movable block and the bottom end of the sleeve rod, and pressure rollers are rotatably inserted into the two sets of movable blocks.

[0009] Furthermore, the adhesive application assembly includes adhesive application heads fixedly installed on the inner walls of both sides of the frame. The adhesive application head is used to apply adhesive to the surface of the substrate. The input end of the adhesive application head is fixedly connected to an adhesive supply pipe, and a pump body is provided on the surface of the adhesive application head.

[0010] Furthermore, the dust removal assembly includes two sets of second motors fixedly mounted on the surface of the frame, and the output ends of the second motors are fixedly connected to rotating shafts, with brushes fixedly sleeved on the surface of the rotating shafts. Furthermore, the brush rollers contact the bonding surface of the substrate, and the rotation of the brushes is used for dust removal from the substrate surface.

[0011] The beneficial effects of this utility model are as follows:

[0012] The first motor drives the conveyor roller located below the pressure roller to rotate, providing the main force to the substrate. Before passing through the adhesive coating assembly, the substrate passes through the dust removal assembly, where a high-speed rotating brush mechanically sweeps the surface of the substrate to remove attached dust and fibers. The removed impurities leave the surface of the substrate under the negative pressure or gravity of the frame, thereby preventing bubbles or white spots from forming in the subsequent adhesive layer, ensuring the composite strength and appearance quality. The adhesive between the substrates is then dried by an electric heating wire. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0022] like Figures 1 to 4 As shown, a rapid lamination device for food packaging bags includes a frame 1, with an elastic pressure application component 2 disposed at a through groove 11 on the surface of the frame 1, and a pressure roller 3 rotatably mounted on the elastic pressure application component 2; as shown Figure 1 , Figure 2 and Figure 3 As shown, specifically, the elastic pressure application component 2 includes a sleeve rod 201 fixedly installed on the top of the through groove 11, and a rod body 202 is movably inserted into the bottom end of the sleeve rod 201. A movable block 203 is fixedly installed at the bottom end of the rod body 202, and the movable block 203 slides vertically in the through groove 11. A spring 204 is fixedly connected to the top surface of the movable block 203 and the bottom end of the sleeve rod 201. Pressure rollers 3 are rotatably inserted into the two sets of movable blocks 203.

[0023] More specifically, the spring 204 always applies a downward elastic force to the movable block 203, causing the pressure roller 3 to elastically press the substrate. The spring 204 also allows the pressure to adapt to changes in the substrate thickness, ensuring that the pressing operation is carried out after the substrate is coated with adhesive.

[0024] Several sets of equidistant conveyor rollers 4 are rotatably inserted into the two side walls of the frame 1, and a first motor 41 is fixedly mounted on the surface of the frame 1. The output end of the first motor 41 is fixedly connected to the conveyor roller 4 located directly below the pressure roller 3. An adhesive application assembly 6 is provided inside the frame 1; Figure 2 and Figure 4 As shown, specifically, the adhesive application assembly 6 includes adhesive application nozzles 601 fixedly installed on the inner walls of both sides of the frame 1. The adhesive application nozzles 601 are used to apply adhesive to the surface of the substrate. The input end of the adhesive application nozzles 601 is fixedly connected to the adhesive supply pipe 602, and the surface of the adhesive application nozzles 601 is provided with a pump body 603.

[0025] More specifically, the adhesive is delivered to the coating nozzle 601 via the glue supply pipe 602 through the pump body 603; the adhesive is then sprayed onto the cleaned surface of the substrate in a quantitative and uniform manner through the coating nozzle 601. Since the dust has been removed in the cleaning process, the adhesive can directly wet the surface of the substrate to form a continuous and defect-free adhesive layer.

[0026] The frame 1 is equipped with a dust removal component 7, which is used to clean surface impurities of the substrate; such as Figure 2 and Figure 4 As shown, specifically, the dust removal assembly 7 includes two sets of second motors 701 fixedly installed on the surface of the frame 1, and the output end of the second motors 701 is fixedly connected to a rotating shaft 702, and a brush roller 703 is fixedly sleeved on the surface of the rotating shaft 702.

[0027] More specifically, the two sets of second motors 701 drive the rotating shaft 702 to rotate at high speed; the bristles of the brush roller 703 on the rotating shaft 702 are in direct contact with the substrate surface, and the tangential force generated by the rotation peels off the dust. The rotation speed of the brush roller 703 is matched with the linear speed of the conveying roller 4 to ensure that the number of brushing times per unit area is constant and to avoid missed brushing.

[0028] like Figure 4 As shown, in some practical applications, the brush roller 703 contacts the bonding surface of the substrate, and the rotation of the brush roller 703 is used to clean the surface of the substrate.

[0029] More specifically, the outer surface of the brush roller 703 is bonded to the substrate, and dust removal is achieved through rotational friction; the brush bristles are made of antistatic nylon to reduce secondary adsorption.

[0030] Two sets of electric heating wires 8 are fixedly installed on the inner wall of the frame 1.

[0031] like Figure 4 As shown, the first limiting roller 12 and the second limiting roller 13 are rotatably inserted into the two side walls of the frame 1. The surface of the frame 1 is provided with a feeding groove 14, and the packaging bag substrate roll 5 is rotatably placed in the feeding groove 14.

[0032] More specifically, the first limiting roller 12 and the second limiting roller 13 on both sides of the frame 1 are used to limit and guide the substrate, and the feeding groove 14 on the surface of the frame 1 enables the upper and lower packaging bag substrate rolls 5 to be rotated and placed.

[0033] In summary: The first motor 41 drives the conveyor roller 4 located below the pressure roller 3 to rotate, so as to provide the main force for the substrate. Before passing through the adhesive coating assembly 6, the substrate passes through the dust removal assembly 7, where a high-speed rotating brush mechanically brushes the surface of the substrate to remove the attached dust and fibers. The removed impurities leave the surface of the substrate under the negative pressure or gravity of the frame 1, thereby avoiding the formation of bubbles or white spots in the subsequent adhesive layer, ensuring the composite strength and appearance quality. The adhesive between the substrates is then dried by the electric heating wire 8.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
