DETAILED DESCRIPTION

[0022] The utility model will be further described in connection with the drawings.

[0023] The special-shaped roller coating device of the utility model, as shown in Figures 1 to 3 , including coating roller 2, coating roller driving mechanism 3 and scraper bar 6, coating roller driving mechanism 3 drives coating roller 2 to rotate, and the axis of coating roller 2 is vertically arranged, and scraper bar 6 is attached to the back side of coating roller 2, and scraper bar 6 includes round bar body 60, as Figure 1As shown, the coating roller 2 includes a roller body 21, meaning that the round bar body 60 is attached to the rear side of the roller body 21, as... Figures 1 to 3 As shown, the roller body 21 has an irregularly shaped annular groove 211 formed on it to accommodate the irregularly shaped side 991 of the plate 99. That is, the irregularly shaped annular groove 211 is a groove with an irregular cross-section that extends around the entire circumference. An irregularly shaped scraper block 61 is formed on the front side of the scraper 6. The irregularly shaped scraper block 61 is fitted into the irregularly shaped annular groove 211. In other words, the irregularly shaped scraper block 61 protrudes radially from the round rod body 60, and the shape of the irregularly shaped scraper block 61 matches the irregularly shaped side 991. For example, the irregularly shaped side 991 can be a convex arc side, then the irregularly shaped annular groove 211 is a concave arc groove; such as Figure 1 and Figure 2 As shown, the irregular roller coating device of this utility model also includes a scraper lateral adjustment mechanism 5. The scraper lateral adjustment mechanism 5 drives the scraper 6 to move back and forth. In other words, the scraper 6 is slidably set back and forth, and the scraper 6 can be adjusted back and forth by the scraper lateral adjustment mechanism 5. The scraper lateral adjustment mechanism 5 can drive the scraper 6 to adjust back and forth by electric or manual means.

[0024] like Figure 1 and Figure 2 As shown, the coating roller drive mechanism 3 drives the coating roller 2 clockwise (in... Figure 5 Rotate (from the visual direction), such as Figure 5 As shown, paint is sprayed onto the left rear part of the coating roller 2, which can be done by spraying paint directly onto the irregular annular groove 211, so that the irregular annular groove 211 is covered with paint. As the coating roller 2 rotates, the paint reaches the position of the scraper 6. Since the scraper 6 is close to the rear side of the coating roller 2 (specifically the right rear side), and the irregular scraper 61 is adapted to be set inside the irregular annular groove 211, the excess paint on the cylindrical roller body 21 is scraped off by the outer cylindrical surface of the scraper 6, and the excess paint on the inner wall of the irregular annular groove 211 is also scraped off by the irregular scraper 61. Figure 2 As shown, when the sheet material 99 moves to the left past the coating roller 2, the irregularly shaped side 991 adapts to the irregularly shaped annular groove 211. That is to say, the surface of the irregularly shaped side 991 can adapt to and abut the inner wall of the irregularly shaped annular groove 211. Since the irregularly shaped annular groove 211 is annular, the inner wall of the irregularly shaped annular groove 211 gradually approaches the irregularly shaped side 991 of the sheet material 99. Therefore, the paint on the inner wall of the irregularly shaped annular groove 211 has an action of adhering to the irregularly shaped side 991, so that the paint attached to the inner wall of the irregularly shaped annular groove 211 is transferred and adhered to the irregularly shaped side 991 of the sheet material 99. Figure 4 As shown, since the irregularly shaped scraper 61 is circumferentially extended, as Figure 6As shown, this allows excess paint scraped off by the shaped scraper 61 to be quickly discharged between the shaped scraper 61 and the inner wall of the shaped annular groove 211; however, assuming the shaped scraper 61 is a straight extension, since the tangential sides of the part where the shaped scraper 61 and the shaped annular groove 211 are in contact are relatively narrow, it is not conducive to the scraped paint quickly leaving the part where the shaped scraper 61 and the shaped annular groove 211 are in contact. Figure 6 As shown, since the scraper 6 does not need to rotate, the irregularly shaped scraper block 61 can be set to extend circumferentially by approximately 90° to 150°. When the irregularly shaped side 991 is a convex trapezoidal side, the cross-section of the irregularly shaped annular groove 211 is correspondingly processed into a trapezoidal shape. When it is necessary to increase the amount of paint applied to the irregularly shaped side 991, the irregularly shaped scraper block 61 is moved back and adjusted, which slightly increases the gap between the irregularly shaped annular groove 211 and the irregularly shaped scraper block 61, allowing more paint to remain on the inner wall of the irregularly shaped annular groove 211, and the amount of paint transferred to the irregularly shaped side 991 will increase accordingly; similarly, when it is necessary to reduce the amount of paint applied to the irregularly shaped side 991, the irregularly shaped scraper block 61 is moved forward and adjusted.

[0025] As can be seen from the above, by setting the irregular annular groove 211 structure, the roller coating device of the present invention can effectively coat the irregular side of the plate, and the structural modification is small, so the manufacturing cost is low. Moreover, the manufacturing cost and production cost of the roller coating device of the present invention are relatively low compared with the spraying device, indicating that the irregular roller coating device of the present invention is beneficial to cost reduction.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, the roller coating device of this utility model also includes a support 1, which includes a horizontal plate 11 and a vertical plate 12. The upper end of the vertical plate 12 is fixedly connected (welded) to one end of the horizontal plate 11. The coating roller drive mechanism 3 includes a rotating support 33 and a rotating shaft 34. The coating roller 2 is coaxially mounted on the rotating shaft 34, that is, the rotating shaft 34 coaxially passes through the coating roller 2. Therefore, the axis of the rotating shaft 34 is vertically set. The rotating support 33 is mounted on the horizontal plate 11, and the rotating shaft 34 is rotatably connected to the rotating support 33 through a corresponding bearing. Specifically, the rotating shaft 34 passes through the rotating support 33. Figure 2 As shown, the scraper lateral adjustment mechanism 5 includes a slider 51, a guide seat 52, and an adjustment screw 53. The guide seat 52 is mounted on the vertical plate 12, and the slider 51 is slidably connected to the guide seat 52. For example, the guide seat 52 and the slider 51 are slidably connected through a dovetail groove structure. The adjustment screw 53 is rotatably connected to the vertical plate 12 and screwed onto the slider 51. The scraper 6 is located at the front end of the slider 51. Therefore, when the adjustment screw 53 is rotated electrically or manually, it can drive the slider 51 to move back and forth, thus allowing the scraper 6 to move back and forth for adjustment. The above adjustment mechanism has a simple structure and low cost. Specifically, as shown... Figure 2As shown, the rear end of the position adjusting screw 53 is provided with a hand wheel, i.e. the position adjusting screw 53 can be driven to rotate by manual operation. Figures 1 to 3 As shown, the coating roller driving mechanism 3 further comprises a motor 31 and a speed reducer 32, the speed reducer 32 is a worm and gear speed reducer, the speed reducer 32 is installed at the upper end of the rotating support seat 33, the motor 31 is installed at the input end of the speed reducer 32, the output end of the speed reducer 32 is a hollow shaft, and thus the upper end of the rotating shaft 34 is installed in the output end of the speed reducer 32.

[0027] Further, as shown in Figure 1 and Figure 2 As shown, the front end of the sliding block 51 is provided with a squeegee seat 4, as shown in Figure 5 As shown, the front part of the squeegee seat 4 is formed with a vertical sliding groove 41, i.e. the vertical sliding groove 41 is arranged extending along the up-down direction, specifically, the right side wall of the vertical sliding groove 41 is integrally arranged with the sliding block 51, as shown in Figure 1 As shown, the rear part of the squeegee seat 4 is formed with a vertical position adjusting long hole 401, i.e. the vertical position adjusting long hole 401 is arranged extending along the up-down direction, the vertical position adjusting long hole 401 communicates with the vertical sliding groove 41, as shown in Figure 4 As shown, the rear part of the squeegee 6 is formed with a mounting plane 601, the mounting plane 601 is formed with a mounting screw hole 6011, as shown in Figure 5 As shown, the squeegee 6 is arranged in the vertical sliding groove 41, the mounting plane 601 abuts against the bottom of the vertical sliding groove 41, the vertical position adjusting long hole 401 is installed with a fixing screw 42, the fixing screw 42 is screwed with the mounting screw hole 6011, thus loosening the fixing screw 42 can make the squeegee 6 position adjusting up-down (parallel to the coating roller 2) in the vertical sliding groove 41, during assembly, it is convenient to adapt the height position of the special-shaped squeegee block 61 to the special-shaped ring groove 211, during which the fixing screw 42 can slide in the vertical position adjusting long hole 401.

[0028] Further, as shown in Figure 2 and Figure 5 As shown, the vertical plate 12 is installed with a support block 13 through corresponding screws, the position adjusting screw 53 passes through the support block 13, specifically, the support block 13 is installed with a thrust ball bearing, the rear end of the position adjusting screw 53 is connected with the support block 13 through the thrust ball bearing, the squeegee transverse position adjusting mechanism 5 comprises a locking handle 54, the locking handle 54 is formed with a stud portion 451, the stud portion 451 is screwed with the support block 13, the end of the stud portion 451 abuts against and connects the position adjusting screw 53 radially (i.e. along the radius direction of the position adjusting screw 53), thus rotating the locking handle 54 to make the stud portion 451 away from the position adjusting screw 53 can make the position adjusting screw 53 rotate to position the special-shaped squeegee block 61, and when the locking handle 54 is screwed, the static friction resistance of the stud portion 451 to the position adjusting screw 53 can avoid the position adjusting screw 53 from rotating, thus the special-shaped squeegee block 61 can be avoided from shifting during normal coating process.

[0029] Further, as shown in Figure 3 the upper and lower ends of the coating roller 2 are respectively formed with shaft heads 22, that is to say, the roller body 21 is located between the upper and lower shaft heads 22, the upper end of the rotating shaft 34 is formed with a convex ring 341, the rotating shaft 34 is coaxially fitted through the shaft heads 22, and the convex ring 341 is abutted to connect the corresponding shaft head 22 (that is to say, the upper end surface of the shaft head 22 located at the upper position is abutted to connect the lower end surface of the convex ring 341), so that the coating roller 2 is positioned at the lower side of the convex ring 341, and the shaft heads 22 and the rotating shaft 34 can be connected by means of a flat key.

[0030] In some embodiments, as shown in Figure 3 the lower end of the rotating shaft 34 is screwed with a nut 7, and the coating roller 2 is clamped between the convex ring 341 and the nut 7. Thus, the coating roller 2 is axially positioned. When it is necessary to replace the coating roller 2, the special-shaped scraping block 61 is first moved away from the special-shaped ring groove 211 by the scraping rod transverse positioning mechanism 5, then the nut 7 is disassembled, and then the coating roller 2 is moved downward to be separated from the rotating shaft 34. During this period, as shown in Figure 2 an operating hole 221 can be provided on the shaft head 22 located at the lower position, a cross screwdriver is first inserted into the operating hole 221, and then the nut 7 is rotated by using a wrench.

[0031] In some embodiments, as shown in Figure 7 and Figure 8 the lower end of the rotating shaft 34 is formed with a conical hole 3401, specifically, the conical hole 3401 is machined on the outer cylindrical surface of the rotating shaft 34, the axis of the conical hole 3401 is along the radial direction of the rotating shaft 34, a positioning screw hole 222 is formed on the shaft head 22, a positioning screw 8 is screwed and installed in the positioning screw hole 222, and the end of the positioning screw 8 is formed with a conical head 801, as shown in Figure 7 the conical head 801 is adapted to connect the conical hole 3401; thus, the conical hole 3401 blocks the axial and circumferential displacement of the shaft head 22, so that the rotating shaft 34 and the coating roller 2 are relatively positioned with high strength, and the above-mentioned flat key, operating hole 221 and nut 7 can be omitted. When it is necessary to disassemble the coating roller 2, the special-shaped scraping block 61 is first moved away from the special-shaped ring groove 211, and then the positioning screw 8 is rotated away from the positioning screw hole 222, so that the coating roller 2 can be moved downward to be separated from the rotating shaft 34, and the operation process is relatively simple. The positioning screw hole 222 can be specifically formed on the shaft head 22 located at the lower position. During the process of rotating and inserting the conical head 801 into the conical hole 3401, the conical hole 3401 can guide the conical head 801 to gradually coaxially align the conical head 801 with the conical hole 3401, so that the operation requirement of the worker is not high during the installation of the positioning screw 8.
