Description

Technical Field

[0001] This utility model belongs to the technical field of coating devices and relates to an adhesive coating device. Background Technology

[0002] Adhesive bonding refers to the technique of joining the surfaces of homogeneous or heterogeneous objects together with adhesives. It features continuous stress distribution, light weight, sealing, and low processing temperature in most processes. Adhesive bonding technology is particularly suitable for joining different materials, thicknesses, ultra-thin specifications, and complex components. Adhesives have seen the fastest development in modern times, have a wide range of applications, and have a significant impact on the advancement of high-tech science and technology and the improvement of people's daily lives. Therefore, the research, development, and production of various adhesives are of great importance.

[0003] The following technical problems were found in the existing technology: When applying traditional adhesives, it is necessary to use a flat putty knife for manual application. When applying the adhesive, firstly, it is not possible to ensure that the thickness of the coating is uniform, resulting in uneven thickness; secondly, it is not possible to apply the adhesive along a straight line, resulting in inconsistent shapes. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when using a flat putty knife for manual scraping, it is impossible to guarantee a uniform thickness of the putty, resulting in uneven thickness. Furthermore, it is impossible to scrape along straight lines, leading to inconsistent shapes.

[0005] The adhesive scraping device described in this utility model includes a base plate, a support plate symmetrically and fixedly connected to the top surface of the base plate, an electric push rod fixedly connected to each opposite side of the support plate, a clamping mechanism provided at the output end of the electric push rod, hydraulic cylinders fixedly connected to both sides of the top surface of the base plate, an adjusting frame fixedly connected to the output end of the hydraulic cylinders, a mounting frame fixedly connected to one side of the adjusting frame, a servo motor mounted on the top of the mounting frame, a lead screw fixedly connected to the output end of the servo motor, the lead screw being rotatably connected to the adjusting frame, a sliding seat threadedly connected to the outer side of the lead screw, and a scraping mechanism provided below the sliding seat.

[0006] The clamping mechanism includes a clamping plate and a limiting plate. The output end of the electric push rod is fixedly connected to the clamping plate. The top surface of the base plate and the corresponding position of the clamping plate are symmetrically fixedly connected to the limiting plate. The clamping plate and the limiting plate are slidably connected.

[0007] A limiting rod is symmetrically fixedly connected to one side of the adjusting frame and to the corresponding position of the lead screw. A limiting hole is opened at the corresponding position of the sliding seat and the limiting rod. The limiting rod is slidably connected to the sliding seat through the limiting hole.

[0008] The coating mechanism includes an extension plate, a groove, a coating plate, and a second lead screw. The extension plate is fixedly connected to both ends of the bottom surface of the sliding seat. A groove is opened on the opposite side of the extension plate. The coating plate is slidably connected inside the groove. A connecting plate is fixedly connected to the side of the coating plate away from the servo motor. The second lead screw is rotatably connected inside the connecting plate. The second lead screw is threadedly connected to the sliding seat.

[0009] The coating mechanism also includes a coating roller and a feeding trough. The extension plate is rotatably connected to the coating roller, and the side of the extension plate away from the coating plate is fixedly connected to the feeding trough. The cross-section of the feeding trough is a trapezoid with a larger top and a smaller bottom.

[0010] The scraping mechanism also includes a bidirectional lead screw, a slider, and a sealing plate. The extension plate is rotatably connected to the bidirectional lead screw on the side near the material discharge trough. The slider is symmetrically threaded to the outside of the bidirectional lead screw. The bottom end of the slider is fixedly connected to the sealing plate. The sealing plate extends to the material discharge trough outlet and contacts the outlet.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The hydraulic cylinder can drive the adjustment frame to move, which in turn drives the scraping mechanism to adjust the height. Then, the height of the scraping plate is precisely adjusted by the lead screw to control the thickness of the adhesive scraping. Then, the servo motor is started, which drives the lead screw to rotate, which in turn drives the scraping plate to scrape along a straight line, so that the scraping shape is uniform.

[0012] 2. The adhesive is initially applied by a scraping roller, and then finely applied by a scraping plate to ensure the coating effect. Rotating the bidirectional screw can drive the slider to move, which in turn can drive the closing plate to move, thereby adjusting the length of the discharge port of the feeding trough to accommodate the coating of items of different widths, reduce adhesive waste, and prevent a large amount of adhesive from falling onto the base plate, which would increase the subsequent cleaning and maintenance work.

[0020] like Figures 1-6As shown, an adhesive scraping device includes a base plate 1. A support plate 2 is symmetrically and fixedly connected to the top surface of the base plate 1. Electric push rods 3 are fixedly connected to opposite sides of the support plate 2. The electric push rods 3 can drive a clamping mechanism. The output end of the electric push rods 3 is provided with a clamping mechanism. Hydraulic cylinders 6 are fixedly connected to both sides of the top surface of the base plate 1. The hydraulic cylinders 6 can drive an adjusting frame 7 to move up and down, making a rough adjustment of the height of the scraping mechanism. The output end of the hydraulic cylinder 6 is fixedly connected to the adjusting frame 7. A mounting frame 8 is fixedly connected to one side of the adjusting frame 7. A servo motor 801 is mounted on the top of the mounting frame 8. The servo motor 801 can drive an adjusting frame 7 to drive a clamping mechanism. The scraping mechanism can be moved horizontally by the lead screw 9. The output end of the servo motor 801 is fixedly connected to the lead screw 9. The lead screw 9 is rotatably connected to the adjusting frame 7. The outer side of the lead screw 9 is threadedly connected to the sliding seat 11. The adjusting frame 7 is symmetrically fixedly connected to the limit rod 10 on the opposite side and at the corresponding position of the lead screw 9. The sliding seat 11 and the limit rod 10 are respectively opened at the corresponding positions. The limit rod 10 is slidably connected to the sliding seat 11 through the limit hole. The limit rod 10 provides guidance for the movement of the sliding seat 11 to prevent the sliding seat 11 from deviating when moving, which would affect the scraping quality. The scraping mechanism is provided below the sliding seat 11.

[0021] The clamping mechanism includes a clamping plate 4 and a limiting plate 5. The output end of the electric push rod 3 is fixedly connected to the clamping plate 4. The top surface of the base plate 1 and the corresponding position of the clamping plate 4 are symmetrically fixedly connected to the limiting plate 5. The clamping plate 4 and the limiting plate 5 are slidably connected. The limiting plate 5 provides guidance for the movement of the clamping plate 4 and prevents the clamping plate 4 from shaking or deviating when it moves.

[0022] In use, first place the item to be coated between the two clamping plates 4, ensuring that the surface to be coated is higher than the top surface of the clamping plates 4. Then, start the electric push rod 3 to move the clamping plates 4 until the item to be coated is clamped and fixed. Then, start the hydraulic cylinder 6 to move the adjusting frame 7 to make preliminary adjustments to the height of the coating mechanism, which will facilitate subsequent coating operations.

[0023] The coating mechanism includes an extension plate 1101, a groove 1102, a coating plate 12, and a lead screw 1202. The extension plate 1101 is fixedly connected to both ends of the bottom surface of the sliding seat 11. A groove 1102 is opened on the opposite side of the extension plate 1101. The coating plate 12 is slidably connected inside the groove 1102. A connecting plate 1201 is fixedly connected to the side of the coating plate 12 away from the servo motor 801. The lead screw 1202 is rotatably connected inside the connecting plate 1201. The lead screw 1202 is threadedly connected to the sliding seat 11. The height of the coating plate 12 can be finely adjusted by the lead screw 1202 to control the coating thickness of the adhesive.

[0024] The coating mechanism also includes a coating roller 13 and a feeding trough 14. The extension plate 1101 is rotatably connected to the coating roller 13, which can perform preliminary coating of the adhesive to make its distribution more uniform. The feeding trough 14 is fixedly connected to the side of the extension plate 1101 away from the coating plate 12.

By moving the closing plate 1601 through the bidirectional lead screw 15, the size of the outlet of the feeding trough 14 can be adjusted to accommodate the coating of items of different sizes and reduce adhesive waste.

[0025] In use, the height of the scraper plate 12 is finely adjusted by the lead screw 1202 to control the thickness of the adhesive coating. Rotating the bidirectional lead screw 15 moves the slider 16, which in turn moves the closing plate 1601, thereby adjusting the length of the discharge port of the feeding trough 14 to accommodate items of different widths, reduce adhesive waste, and prevent a large amount of adhesive from falling onto the base plate 1, thus increasing subsequent cleaning and maintenance work. Then, the servo motor 801 is started, which drives the lead screw 9 to rotate, thereby moving the sliding seat 11 and the scraping mechanism. The scraper roller 13 then performs initial scraping of the adhesive, followed by fine scraping by the scraper plate 12 to ensure the scraping effect and uniform scraping shape.

[0026] During operation, the workpiece to be coated is first placed between the two clamping plates 4, ensuring that the surface to be coated is higher than the top surface of the clamping plates 4. Then, the electric push rod 3 is activated to move the clamping plates 4 until the workpiece is clamped and fixed. Next, the hydraulic cylinder 6 is activated to move the adjusting frame 7, making an initial adjustment to the height of the coating mechanism to facilitate subsequent coating operations. The height of the coating plate 12 is finely adjusted by the lead screw 1202 to control the thickness of the adhesive coating. Rotating the bidirectional lead screw 15 moves the slider 16. 16 can drive the closing plate 1601 to move, thereby adjusting the length of the discharge port of the feeding trough 14 to adapt to the scraping of items of different widths, reduce adhesive waste, and prevent a large amount of adhesive from falling on the base plate 1, increasing subsequent cleaning and maintenance work. Then, the servo motor 801 is started, which drives the lead screw 9 to rotate. The lead screw 9 drives the sliding seat 11 to move, thereby driving the scraping roller 13 to perform preliminary scraping of the adhesive. Then, the scraping plate 12 performs fine scraping to ensure the scraping effect and make the scraping shape uniform.
