Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 , 2 As shown in Figure 3, this utility model provides a technical solution: a high-speed laminating device for packaging film in packaging bag production, comprising: two support cabinets 1; three connecting rods 2 are provided and fixed between the two support cabinets 1, two sliding frames 3 are slidably connected to the outer side of the connecting rods 2, and a base film roll 4 is rotatably connected between the two sliding frames 3, a motor 5 is fixedly connected to the outer side of one of the sliding frames 3 for adjusting the rotation speed of the base film roll 4 and the tension of the base film; a transmission roller 6 is rotatably installed above the base film roll 4, and a hydraulic cylinder 8 for correction is fixedly connected to one side of the support cabinet 1; two electric heating rollers 14 are provided above and below and placed between the two support cabinets 1, the electric heating rollers conduct heat to the roller surface through internal heating elements (such as electric heating tubes, electric heating wires), thereby heating the roller body. The surface of the roller body transfers heat to the base film or adhesive layer in contact with it through conduction, the heating effect of the electric heating rollers is uniform, and the temperature can be adjusted with high precision; an electrostatic dust removal box 12 is placed above the electric heating rollers 14. The electrostatic precipitator 12 is fixed to the support cabinet 1 at both ends and is used to remove dust from the surface film. The electrostatic precipitator includes the following components: a high-voltage power supply, discharge electrodes, a dust collection plate or electrode, an electrical control system, and air inlets and outlets. The high-voltage power supply provides high voltage to generate an electrostatic field. The discharge electrodes, such as discharge wires, needle electrodes, or electrode plates, generate an electric field that charges the dust particles. The dust collection plate or electrode collects charged dust particles and can be a metal mesh, metal plate, or a plate with a conductive layer. The electrical control system controls the power supply and electric field strength and performs cleaning when necessary. The air inlets and outlets allow air to flow in and out.
[0024] It should be noted that in this invention, the base film roll 4 with the base film wound around it is placed between two sliding frames 3, and then the base film is wound upwards around multiple drive rollers. Then, the surface film to be laminated is passed through the electrostatic dust removal box 12, passes around the drive roller 4 13 and overlaps with the base film. Then, it is pressed by the electric heating roller 14 to complete the lamination of the packaging film. The winding equipment winds up the pressed film. The motor 5 adjusts the speed of the base film roll 4 and, in conjunction with the traction of the winding equipment, adjusts the tension of the base film through the drive roller and the base film.
[0025] Please see Figure 1 , 2As shown in Figure 3, a hydraulic cylinder 2 15 is fixedly connected to one side inside the support cabinet 1, and the output end of the hydraulic cylinder 2 15 is fixedly connected to the sliding frame 3.
[0026] It should be noted that this utility model uses hydraulic cylinder 215 to drive the sliding frame 3 to move to the sides or the middle. When the sliding frame 3 moves to the sides, it is convenient to remove the base film roll 4. When the sliding frame 3 moves to the middle, it is convenient to clamp the base film roll 4, so that the base film roll 4 can be easily disassembled and installed. It can also be used for base film rolls 4 of different lengths. The end of the base film roll 4 is provided with a groove that cooperates with the motor.
[0027] Please see Figure 1 As shown, a support frame 7 is fixedly connected to the inner side of the support cabinet 1, a transmission roller 6 is movably installed between the two support frames 7, a hydraulic cylinder 8 is fixedly connected to one side of the support frame 7, and the output end of the hydraulic cylinder 8 is rotatably connected to the transmission roller 6. Infrared sensors 9 are fixedly connected to the outer sides of both support frames 7 to detect whether the base film is offset.
[0028] It should be noted that the outer side of the support frame 7 of this utility model is fixed with a U-shaped bracket, and an infrared sensor 9 is fixed in the middle of the bracket. The infrared sensor 9 is set perpendicular to the conveyed base film. When the edge of the base film comes into contact with the infrared sensor 9, the infrared sensor 9 detects the signal and sends it to the controller. The controller controls the hydraulic cylinder-8 to drive the transmission roller-6 to slide in the middle of the support frame 7, thereby correcting and adjusting the base film.
[0029] Please see Figure 1 , 2 As shown in Figure 3, a second transmission roller 10 is rotatably connected between the two support cabinets 1, and a third transmission roller 11 is rotatably connected above the first transmission roller 6. The first transmission roller 6, the second transmission roller 10, and the third transmission roller 11 form a triangular structure.
[0030] It should be noted that an ultraviolet lamp is installed on one side of the transmission roller 11 of this utility model for curing or drying the adhesive coated on the base film. The base film is wrapped around the outside of the transmission roller 6 in turn and then around the outside of the transmission roller 10, and then around the top of the transmission roller 11 and through the middle of the electric heating roller 14, so that the electric heating roller 14 can press it.
[0031] Please see Figure 1 , 2 As shown in Figure 3, two drive rollers 13 for conveying the surface film are rotatably connected at the discharge port of the electrostatic dust collector 12.
[0032] It should be noted that the present invention has two transmission rollers 13 arranged vertically. The top of the upper transmission roller 13 is flush with the outlet of the electrostatic dust removal box 12, and the bottom of the lower transmission roller 13 is located between the two electric heating rollers 14, which facilitates the bonding of the surface film and the base film and the conveying to the middle of the electric heating roller 14.
[0033] Please see Figure 1 , 2 As shown in Figure 3, two hollow rollers 16 are rotatably connected to one side of the electric heating roller 14. The hollow rollers 16 are connected to the cold water source through a rotary joint.
[0034] It should be noted that the two hollow rollers 16 of this invention are connected to a cold water source through a rotary joint. Cold water circulates into the hollow rollers 16 to cool the multi-pressed film, thereby ensuring that the composite film material is stable and does not deform.
