Description

Technical Field

[0001] This utility model relates to the field of adhesive coating thickness adjustment technology, and in particular to a mechanism for precisely adjusting the adhesive coating thickness of impregnated paper. Background Technology

[0002] Impregnated paper is a functional paper treated with a special coating process. Its surface is covered with a uniform adhesive coating through precise coating technology. During the coating process, the paper substrate is fully bonded to the adhesive by immersion or roll coating, and then dried and cured to form a dense and continuous adhesive film. This process not only enhances the paper's mechanical strength, water resistance, impermeability and dimensional stability, but also endows it with excellent bonding properties or special surface characteristics. Impregnated paper is widely used in the fields of artificial board veneer, composite material reinforcement, industrial filtration, packaging protection and electronic insulation, and is an important deep processing method to achieve high performance and functionality of paper.

[0003] A search revealed that the document with publication number "CN217615760U" mentions "a protective film coating machine adhesive thickness adjustment device, including a bracket and an adjustment component for applying adhesive of different thicknesses to the workpiece. The adjustment component includes two fixed plates on one side of the bracket, a first screw on one side of the fixed plates, a motor at one end of the first screw, a movable frame on the outside of the first screw, a second screw on the top of the movable frame, a sliding frame at one end of the second screw, and a scraper on one side of the sliding frame." In use, by setting up the bracket, scraper, cylinder, rack, and gear, the rack drives the gear to rotate, then the gear drives the second screw to rotate, then the sliding frame drives the scraper to slide up and down on the bracket, and then the movable frame, through the sliding frame, drives the scraper to scrape the adhesive on the workpiece surface. This solves the problem that existing equipment cannot easily adjust the adhesive thickness, easily leading to uneven adhesive thickness and affecting the practicality of the equipment for applying adhesive to workpieces.

[0004] However, traditional glue coating thickness adjustment mechanisms can only adjust the entire metering roller section. They are prone to uneven glue coating thickness due to thermal deformation causing the left and right gaps to become non-parallel. Furthermore, traditional glue coating thickness adjustment mechanisms rely on manual observation and adjustment, which introduces errors and makes it impossible to achieve the ideal glue coating thickness. In addition, traditional glue coating thickness adjustment mechanisms can only apply glue to impregnated paper of a fixed thickness and cannot adapt to impregnated paper of different thicknesses.

[0005] Therefore, we provide a mechanism for precisely adjusting the adhesive coating thickness of impregnated paper to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a mechanism for precisely adjusting the adhesive coating thickness of impregnated paper, aiming to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A precision adhesive coating thickness adjustment mechanism for impregnated paper includes a side plate. A support adjustment assembly is installed at the inner front end of the side plate. The support adjustment assembly includes a base plate installed on the inner side of the side plate. A housing is installed on the upper side of the base plate. A movable lead screw is disposed inside the housing. A connecting sleeve is installed at the upper end of the movable lead screw. A support block is connected to the upper side of the connecting sleeve. A support roller is connected to the inner side of the support block. An adhesive roller is disposed on the upper side of the support roller. A base is connected to the inner rear end of the side plate. A thickness adjustment assembly is installed on the upper side of the base. The thickness adjustment assembly includes a lead screw base plate installed on the upper side of the base. An adjusting lead screw is installed on the upper side of the lead screw base plate. A lead screw slider is connected to the outer side of the adjusting lead screw. A movable plate is connected to the upper side of the lead screw slider. A connecting block is connected to the upper side of the movable plate. A metering roller is connected to the inner side of the connecting block.

[0008] As a further description of the above technical solution: The outer surface of the movable lead screw is connected to a worm wheel, the front side of the worm wheel is connected to a worm, and the end of the worm is connected to a worm motor. The internal thread of the worm wheel meshes with the external thread of the movable lead screw. The worm motor drives the worm to rotate the worm wheel, thereby driving the movable lead screw to perform lifting and lowering movements.

[0009] As a further description of the above technical solution: Two sets of movable lead screws are provided, symmetrical about the support roller. Two sets of worm motors are provided, and the two sets of worm motors drive the worm to rotate synchronously. The movable lead screws are connected to the support block by bolts through connecting sleeves.

[0010] As a further description of the above technical solution: The end of the adjusting screw is connected to a screw motor. There are two sets of adjusting screws, which are symmetrical about the metering roller. The adjusting screws are independently controlled by the two sets of screw motors. The screw motors are servo motors. The screw slider and the screw motor form a forward and backward movement structure through the adjusting screw.

[0011] As a further description of the above technical solution: Guide rails are provided on both the left and right sides of the adjusting screw, and a guide rail slider is provided on the upper side of the guide rail. The guide rail and the screw base plate are bolted together, and the guide rail slider and the moving plate are bolted together.

[0012] As a further description of the above technical solution: A laser sensor is installed on the front side of the connecting block. There are two sets of laser sensors, which are respectively installed on the connecting blocks on the left and right sides of the metering roller. The laser sensor detects the distance between the metering roller and the rubber roller.

[0013] As a further description of the above technical solution: A metering roller motor is installed at the left end of the metering roller. The metering roller motor and the moving plate are welded together. The metering roller motor is a servo motor, which can precisely control the rotation direction and speed of the metering roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a support adjustment component, the connecting sleeve, support block, and support roller are raised and lowered by the moving screw, thereby adjusting the distance between the support roller and the glue roller to accommodate impregnated paper of different thicknesses and improve applicability. Two sets of worm motors synchronously drive the worm to rotate the worm wheel, which in turn drives the moving screws on both sides of the support roller to move synchronously, ensuring that the support roller and the glue roller are parallel, thus ensuring uniform glue coating thickness. At the same time, the two sets of moving screws can better support the support roller, making the structure stable.

[0015] 2. By setting up a thickness adjustment component, two sets of lead screw motors drive the adjusting lead screws, which independently control the moving plates and connecting blocks on the left and right sides of the metering roller to adjust forward and backward. This allows the gap between the metering roller and the glue roller to be adjusted independently on both sides, preventing uneven glue coating thickness caused by factors such as thermal deformation or bearing wear preventing the metering roller from failing to create a parallel gap with the glue roller. By independently adjusting the gap at both ends of the glue roller, the uniformity of the glue coating thickness is ensured more precisely. At the same time, by setting the lead screw motors to servo motors, the left and right gaps can be adjusted more precisely, improving the accuracy of thickness adjustment. By setting guide rail sliders and guide rails, the moving plates are limited during adjustment, making the adjustment process smoother and providing support. By setting up two sets of laser sensors, the distance between the left and right gaps between the metering roller and the glue roller can be detected more accurately, facilitating the adjustment of the left and right gaps of the metering roller and enabling more precise adjustment of the glue coating thickness. The rotation speed and rotation direction of the metering roller are precisely controlled by the metering roller motor, thereby adjusting the magnitude of the shear force on the glue and further controlling the glue coating thickness.

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-4 As shown, this utility model provides a technical solution: a mechanism for precisely adjusting the adhesive coating thickness of impregnated paper, including a side plate 1. A support adjustment assembly 2 is installed on the inner front end of the side plate 1. The support adjustment assembly 2 includes a base plate 201 installed on the inner side of the side plate 1. A housing 202 is installed on the upper side of the base plate 201. A movable screw 203 is provided inside the housing 202. A connecting sleeve 207 is installed on the upper end of the movable screw 203. A support block 3 is connected to the upper side of the connecting sleeve 207. A support roller 4 is connected to the inner side of the support block 3. A glue roller 5 is provided on the upper side of the support roller 4. A base 6 is connected to the inner rear end of 1. A thickness adjustment component 7 is installed on the upper side of the base 6. The thickness adjustment component 7 includes a lead screw base plate 701 installed on the upper side of the base 6. An adjusting lead screw 702 is installed on the upper side of the lead screw base plate 701. A lead screw slider 704 is connected to the outer side of the adjusting lead screw 702. A moving plate 707 is connected to the upper side of the lead screw slider 704. A connecting block 708 is connected to the upper side of the moving plate 707. A metering roller 8 is connected to the inner side of the connecting block 708.

[0020] Furthermore, a worm gear 204 is connected to the outer surface of the movable lead screw 203, a worm 205 is connected to the front side of the worm gear 204, and a worm motor 206 is connected to the end of the worm 205. The internal thread of the worm gear 204 meshes with the external thread of the movable lead screw 203. The worm motor 206 drives the worm 205 to rotate the worm gear 204, thereby driving the movable lead screw 203 to perform lifting and lowering movements. The lifting and lowering of the movable lead screw 203 drives the connecting sleeve 207, the support block 3, and the support roller 4 to lift and lower, thereby adjusting the distance between the support roller 4 and the glue roller 5 to accommodate impregnated paper of different thicknesses and improve applicability.

[0021] Furthermore, two sets of movable lead screws 203 are provided, symmetrical about the support roller 4. Two sets of worm motors 206 are also provided, and the two sets of worm motors 206 synchronously drive the worm 205 to rotate. The movable lead screws 203 are bolted to the support block 3 through the connecting sleeve 207. The synchronous drive of the worm 205 by the two sets of worm motors 206 drives the worm wheel 204 to rotate, which drives the movable lead screws 203 on both sides of the support roller 4 to move up and down synchronously. This ensures that the support roller 4 and the glue roller 5 are parallel, thereby ensuring uniform glue coating thickness. At the same time, the two sets of movable lead screws 203 can better support the support roller 4, making the structure stable.

[0022] Furthermore, a screw motor 703 is connected to the end of the adjusting screw 702. Two sets of adjusting screws 702 are provided and are symmetrical about the metering roller 8. The adjusting screws 702 are independently controlled by the two sets of screw motors 703. The screw motors 703 are servo motors. The screw slider 704 and the screw motors 703 form a forward and backward movement structure through the adjusting screws 702. By driving the adjusting screws 702 with the two sets of screw motors 703, the moving plates 707 and connecting blocks 708 on the left and right sides of the metering roller 8 are individually adjusted forward and backward. This allows the gap between the metering roller 8 and the glue roller 5 to be adjusted independently on the left and right sides. This avoids the metering roller 8 from failing to form a parallel gap with the glue roller 5 due to factors such as thermal deformation or bearing wear, which would result in uneven glue coating thickness. By independently adjusting the gap at both ends of the glue roller 5, the uniformity of glue coating thickness is ensured more precisely. At the same time, by setting the screw motors 703 to be servo motors, the left and right gaps can be adjusted more precisely, improving the accuracy of thickness adjustment.

[0023] Furthermore, guide rails 705 are provided on both the left and right sides of the adjusting screw 702, and guide rail sliders 706 are provided on the upper side of the guide rails 705. The guide rails 705 and the screw base plate 701 are bolted together, and the guide rail sliders 706 and the moving plate 707 are bolted together. By setting the guide rail sliders 706 and the guide rails 705, the moving plate 707 is limited during adjustment, making the adjustment process more stable and providing support.

[0024] Furthermore, a laser sensor 709 is installed on the front side of the connecting block 708. Two sets of laser sensors 709 are provided and are respectively installed on the connecting blocks 708 on the left and right sides of the metering roller 8. The laser sensor 709 detects the distance between the metering roller 8 and the glue roller 5. By setting two sets of laser sensors 709, the distance between the left and right gaps between the metering roller 8 and the glue roller 5 can be detected more accurately, which facilitates the adjustment of the left and right gaps of the metering roller 8 and can more accurately adjust the glue coating thickness.

[0025] Furthermore, a metering roller motor 9 is installed at the left end of the metering roller 8. The metering roller motor 9 and the moving plate 707 are welded together. The metering roller motor 9 is a servo motor. The metering roller motor 9 can precisely control the rotation direction and rotation speed of the metering roller 8. By precisely controlling the rotation speed and rotation direction of the metering roller 8 through the metering roller motor 9, the magnitude of the shear force on the adhesive can be adjusted, thereby further controlling the coating thickness.

[0026] Working principle: The equipment is installed in the working position. Based on the thickness of the impregnated paper, two sets of worm gear motors 206 on the upper side of the base plate 201 drive the worm gear 205 inside the housing 202 to rotate, simultaneously driving two sets of moving screws 203 to move the support block 3 and support roller 4 on the upper side of the connecting sleeve 207, thus adjusting the gap between the support roller 4 and the glue roller 5 to a suitable size. Then, based on the required glue thickness, by observing the data on two sets of laser sensors 709, the screw motors 703 on the screw base plate 701 on the upper side of the two sets of base plates 6 drive the adjusting screw 702 to move the upper side of the screw slider 704. The plate 707 and connecting block 708 are adjusted back and forth, and the gap between the metering roller 8 and the glue roller 5 is adjusted left and right separately, thereby precisely adjusting the glue coating thickness. At the same time, by setting guide rail slider 706 and guide rail 705, the moving plate 707 is limited during adjustment, making the adjustment process more stable. During operation, the glue is poured onto the gap between the metering roller 8 and the glue roller 5 on the inner side of the side plate 1. As the metering roller 8 and the glue roller 5 rotate, the glue is evenly covered on the glue roller 5. The glue-impregnated paper passes through the gap between the support roller 4 and the glue roller 5 to apply glue. At the same time, the metering roller motor 9 precisely controls the rotation speed and rotation direction of the metering roller 8, further precisely adjusting the glue coating thickness.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
