DETAILED DESCRIPTION

[0020] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0021] like Figure 1-3 As shown, a novel double-sided coating mechanism includes a frame 1, on which a first coating roller 2, a second coating roller 3 and a glue leveling roller assembly 4 are arranged in sequence along the length direction of the frame 1, a scraper assembly is fixedly arranged on the first coating roller 2 and the second coating roller 3 on the frame 1, and the first coating roller 2 and the second coating roller 3 are staggered; the first coating roller 2, the second coating roller 3 and the glue leveling roller assembly 4 are all driven by a transmission mechanism 5.

[0022] like Figure 4 As shown, the structure of the transmission mechanism 5 is explained below. The transmission mechanism 5 includes a motor 51 fixed to one side of the frame 1, and the rotating shaft of the motor 51 is connected to one end of the universal coupling 52 through a flange, and the other end of the universal coupling 52 faces the frame 1, and is connected to one end of the first coating roller 2, one end of the second coating roller 3 or one end of the glue-leveling roller assembly 4 by a flange, so that when the rotating shaft of the motor 51 rotates, the first coating roller 2, the second coating roller 3 and the glue-leveling roller assembly 4 can be driven to rotate by the universal coupling 52, and the existence of the universal coupling 52 can make it unnecessary for the motor 51 and the first coating roller 2, the second coating roller 3 and the glue-leveling roller assembly 4 to always maintain a consistent lateral position.

[0023] In some embodiments, the motor 51 is arranged facing the ground to reduce the space it occupies horizontally. At this time, the rotating shaft of the motor 51 is also vertically downward. At this time, a gear assembly is required to complete the rotation. A driving gear is coaxially fixed on the rotating shaft of the motor 51, and the driven gear is arranged perpendicular to the driving gear and the driven gear is meshed with the driving gear. The driven gear is coaxially fixed on another driven shaft. One end of the universal coupling 52 is connected to one end of the driven shaft with a flange, and the other end is connected to one end of the first coating roller 2, one end of the second coating roller 3 or one end of the glue roller assembly 4 with a flange. In this embodiment, bevel gears can be used for both the driving gear and the driven gear.

[0024] It also includes a movable assembly, which includes a first frame 6, a first coating roller 2 is rotatably fixed in the first frame 6, and the first coating roller 2 can rotate freely in the first frame 6, a bearing is mounted on the rotating shaft of the first coating roller 2, and the bearing is embedded in the first frame 6, based on the frame 1 is provided with a groove matching the width of the first frame 6, the first frame 6 is embedded in the groove and can reciprocate along the depth direction of the groove, a cylinder is fixedly provided on the frame 1, and the end of the cylinder telescopic rod is fixedly connected to the first frame 6, and the cylinder drives the first frame 6 to reciprocate up and down on the frame 1. When the cylinder telescopic rod is in the retracted state, the first coating roller 2 is pulled up, and the first coating roller 2 can be cleaned or replaced. When the new double-sided coating mechanism works normally, the cylinder telescopic rod is in an extended state, the first frame 6 is pressed into the embedded groove, and the first coating roller 2 is in a working state. At this time, the material film forms a specific wrap angle on the first coating roller 2 and the second coating roller 3, and the coating liquid in the coating roller mesh pit is transferred to the material film, and the coating is completed on both sides at the same time.

[0025] like Figure 5As shown, the following is a detailed description of the glue leveling roller assembly 4. The glue leveling roller assembly 4 includes a first glue leveling roller 41, a second glue leveling roller 42 and a second frame 43. The first glue leveling roller 41 and the second glue leveling roller 42 are both rotatably fixed in the second frame 43, wherein the second frame 43 includes fixed plates at both ends and a plurality of connecting rods arranged in parallel. The first glue leveling roller 41 and the second glue leveling roller 42 are arranged in parallel with the plurality of connecting rods in the second frame 43, and bearings are arranged at the ends of the first glue leveling roller 41 and the second glue leveling roller 42. In this embodiment, the first glue leveling roller 41 is used as the active roller, and one end of the first glue leveling roller 41 is fixed to a section of the universal coupling 52 of the transmission mechanism 5, so as to realize the rotational drive of the first glue leveling roller 41 by the transmission mechanism 5, and the driving of the second glue leveling roller 42 is completed with the help of a gear set. Specifically, a driving gear is coaxially fixed to a section of the first glue leveling roller 41, and a driven gear is coaxially fixed to a corresponding end of the second glue leveling roller 42. A plurality of transmission gears are arranged between the driving gear and the driven gear, and the driving gear and the driven gear are both meshed with the transmission gear, and the transmission gear is rotatably fixed to the inner side of the fixed plate. In this way, the rotational drive of the first glue leveling roller 41 and the second glue leveling roller 42 can be simultaneously completed by a single transmission mechanism 5.

[0026] The aforementioned rubber-distributing roller assembly 4 can also rotate a certain angle as a whole. A fixed shaft is fixedly arranged on the outer side of the aforementioned fixed plate, and the fixed shaft can be arranged at the center of the fixed plate. The second frame 43 is rotatably fixed in the frame 1 with the fixed shaft. A worm gear is coaxially fixed on the fixed shaft at one end, and a worm is arranged perpendicular to the worm gear. A hand wheel is coaxially fixed at one end of the worm gear, and the worm gear is driven to rotate by the hand wheel, thereby driving the worm gear to complete the rotation, so as to change the angle of the second frame 43 compared with the frame 1. The worm gear can be fixed to the outer side of the frame 1 by a fixed frame 7, and a bearing is arranged in each fixed frame 7 to assist the rotation of the worm gear.

[0027] The first glue-leveling roller 41 and the second glue-leveling roller 42 are chrome-plated optical axes with mirror-finished surfaces. The glue-leveling roller can be detached from the material film when not in operation and does not contact the coating surface. When glue-leveling is required, the rotating mechanism is adjusted to a certain wrap angle between the glue-leveling roller and the material film, and the hand wheel is shaken to rotate around the center through the worm gear mechanism to adjust the wrap angle of the glue-leveling. After adjustment, it can be self-locking. The glue-leveling roller rotates in the opposite direction to the direction of travel of the substrate, and the rotation speed can be adjusted by the transmission mechanism 5. Power is transmitted to one of the glue-leveling rollers through the universal coupling 52, and the other glue-leveling roller transmits power through gears. When the rotation position of the glue-leveling roller changes, the universal coupling 52 can be offset by a certain angle, so the position of the motor 51 and the reducer does not need to be moved.

[0028] like Figure 6As shown, the scraper assembly is described below. The scraper assembly includes a fixing frame 7, which includes a right-angled trapezoidal side plate, and two side plates are vertically fixed by a cross bar. The fixing point is located at the bottom of the right-angled trapezoidal side plate, and the two side plates are connected by a cross plate at the short side of the trapezoid. A plurality of cylinders are fixed on the cross plate, and a pressure block 8 is movably fixed at the end of the telescopic rod of the plurality of cylinders. The pressure block 8 is pressed from the front side of the cross bar to the cross bar, and the scraper is embedded between the pressure block 8 and the cross bar. The up and down movement of the telescopic rod of the cylinder can make the pressure block 8 and the cross bar pressed tightly, thereby completing the fixing of the scraper.

[0029] Slide blocks 9 are fixedly arranged on both sides of the fixed frame 7. The slide blocks 9 are embedded in the slide rails 10 fixedly arranged on both sides of the frame 1. The fixed frame 7 is driven by the screw transmission mechanism 5 to reciprocate forward and backward. A screw is fixedly arranged to rotate through the width direction of the fixed frame 7. A worm wheel is mounted on the screw, and an internal thread that fits the external thread of the screw is arranged on the inner side of the worm wheel. The worm fits the worm wheel vertically, and a hand wheel is coaxially fixed at one end of the worm. Two groups of scraper assemblies are arranged. The worm drives the worm wheel to rotate through the rotation of the hand wheel, so that the fixed frame 7 is driven to move forward and backward on the frame 1 as a whole through the thread on the inner side of the worm wheel and the screw, and the distance between the scraper and the roller is adjusted so that the scraper is pressed against the surface of the first coating roller 2 and the second coating roller 3.

[0030] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
