Description

Technical Field

[0001] This utility model relates to the field of roller coating equipment technology, specifically a paint roller coating machine. Background Technology

[0002] A roller coating machine uses rollers to apply paint, and then uses the rolling motion between the rollers and the sheet material to achieve the coating function. It is mainly used for surface coating operations of sheets or rolls.

[0003] Chinese patent CN222805448U discloses a water-based paint roller coating machine and a conveyor. The conveyor has a support frame above it, and rollers are mounted on the inner side of the support frame. A feeding component is located on the inner wall of the conveyor above the rollers. The rollers include a paint roller and a leveling roller. The leveling roller is rotatably connected to the inner side of the support frame via a second rotating shaft. Slider blocks are rotatably connected to both sides of the paint roller via a first rotating shaft. A groove is formed on the inner wall of the support frame, and the sliders are slidably connected to the inner wall of the groove. A threaded rod is threadedly connected to the inner wall of the support frame, and the end of the threaded rod is rotatably connected to the side wall of the slider. This invention, by incorporating the threaded rod and slider components, allows for adjustment of the pressure between the paint roller and the leveling roller during coating. This ensures reliable paint transfer from the leveling roller to the paint roller and prevents excessive contact pressure between the paint roller and the leveling roller from increasing the load on the equipment components.

[0004] In the above technical solution, the coating is prone to solidification when exposed to air for a long time, which makes the coating stick to the coating roller. The solidified coating will affect the coating effect of the coating roller, so the coating roller needs to be replaced. However, the coating roller in this device is connected to the slider by a rotating shaft, which makes it difficult to disassemble and replace the coating roller, resulting in low practicality of the device.

[0005] Based on this, the present invention proposes a paint roller coating machine. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a paint roller coating machine that can make the limiting block embed into the connecting column by rotating the knob, thereby releasing the restriction on the connecting column. The connecting column can then be pulled out of the paint roller by rotating the column, thus completing the disassembly of the paint roller. This makes the paint roller easy to replace and improves the practicality of the device.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a paint roller coating machine, including a conveyor, two fixed frames are fixedly connected to the conveyor, two sliding frames are slidably connected in the two fixed frames respectively, a rotating shaft is rotatably connected between the two sliding frames, a leveling roller is fixedly connected to the rotating shaft, a feeding component is provided on the leveling roller, and the machine also includes;

[0008] The sliders are slidably connected to two sliding frames respectively. A paint roller is provided between the two sliders. A rotating sleeve is rotatably connected inside the slider. A through groove is provided on both the paint roller and the rotating sleeve. A connecting column is slidably connected in the through groove. Two limiting strips are fixedly connected to the connecting column. A rotating column is fixedly connected to the connecting column.

[0009] Preferably, two threaded rods are rotatably connected to each of the two sliding frames, and the two threaded rods are threadedly connected to the two fixed frames respectively.

[0010] Preferably, each of the two fixed frames has two grooves, and each of the two sliders has two threaded rods rotatably connected to it, with the two threaded rods threadedly connected to the two sliding frames.

[0011] Preferably, two limiting blocks are slidably connected inside the connecting column, and a bidirectional screw is rotatably connected inside the connecting column, with the two limiting blocks respectively threaded to both ends of the bidirectional screw.

[0012] Preferably, a first bevel gear is fixedly connected to the bidirectional screw, a rotating column is rotatably connected inside the connecting column, and a second bevel gear is fixedly connected to the rotating column, with the first bevel gear meshing with the second bevel gear.

[0013] Preferably, a knob is fixedly connected to the rotating column.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] In this invention, when the paint roller needs to be replaced, the knob is turned, and the rotating column rotates accordingly, driving the second bevel gear to rotate. Since the first bevel gear meshes with the second bevel gear, the initial rotation of the bevel gear drives the bidirectional screw to rotate. Since the limiting block is threaded to both ends of the bidirectional screw, the limiting block moves inward as the bidirectional screw rotates, causing the limiting block to embed into the connecting column, thus releasing the limitation of the limiting block on the connecting column. At this time, the rotating column can be pulled away from the paint roller to remove the connecting column from the paint roller, thereby completing the disassembly of the paint roller, facilitating the replacement of the paint roller, and improving the practicality of the device.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved paint roller coating machine. The technical solution of this utility model is as follows:

[0025] like Figures 1-4 As shown, a paint roller coating machine includes a conveyor 1, two fixed frames 2 are fixedly connected to the conveyor 1, two sliding frames 4 are slidably connected inside the two fixed frames 2, a rotating shaft 5 is rotatably connected between the two sliding frames 4, a leveling roller 6 is fixedly connected to the rotating shaft 5, a feeding component 7 is provided on the leveling roller 6, and the machine also includes;

[0026] Two sliders 9 are slidably connected to two sliding frames 4 respectively. A paint roller 11 is provided between the two sliders 9. A rotating sleeve 13 is rotatably connected inside the slider 9. A through groove 12 is provided on both the paint roller 11 and the rotating sleeve 13. A connecting post 15 is slidably connected in the through groove 12. Two limit strips 16 are fixedly connected to the connecting post 15. A rotating post 14 is fixedly connected to the connecting post 15. By rotating the knob 22, the limit block 17 is embedded in the connecting post 15, releasing the restriction on the connecting post 15. The connecting post 15 can then be pulled out from the paint roller 11 by rotating the post 14, thereby completing the disassembly of the paint roller 11. This makes the paint roller 11 easy to replace and improves the practicality of the device.

[0027] Furthermore, such as Figure 1As shown, two threaded rods 8 are rotatably connected to the two sliding frames 4 respectively. The two threaded rods 8 are threaded to the two fixed frames 2 respectively. By rotating the threaded rods 8, the sliding frames 4 are moved to adjust the distance between the paint roller 11 and the conveying surface of the conveyor 1 to accommodate boards of different thicknesses.

[0028] Furthermore, such as Figure 1 As shown, two grooves 3 are respectively opened on the two fixed frames 2, and two threaded rods 10 are rotatably connected to the two sliders 9 respectively. The two threaded rods 10 are respectively threaded to the two sliding frames 4. By rotating the threaded rods 10, the distance between the paint roller 11 and the uniform roller 6 is adjusted to facilitate better paint transfer.

[0029] Furthermore, such as Figures 2-4 As shown, two limiting blocks 17 are slidably connected inside the connecting column 15, and a bidirectional screw 18 is rotatably connected inside the connecting column 15. The two limiting blocks 17 are threaded to the two ends of the bidirectional screw 18 respectively. By rotating the bidirectional screw 18, the two limiting blocks 17 are driven to move towards or away from each other.

[0030] Furthermore, such as Figure 2 and Figure 4 As shown, a bevel gear 19 is fixedly connected to the bidirectional screw 18, and a rotating column 20 is rotatably connected inside the connecting column 15. A bevel gear 21 is fixedly connected to the rotating column 20. The bevel gear 19 and the bevel gear 21 mesh with each other. Through the cooperation of the bevel gear 19 and the bevel gear 21, the bidirectional screw 18 and the rotating column 20 rotate synchronously.

[0031] Furthermore, such as Figure 2 and Figure 4 As shown, a knob 22 is fixedly connected to the rotating column 20. The cross section of the knob 22 is in the shape of a cross, which makes it easy for the user to rotate the rotating column 20 by rotating the knob 22.

[0032] The specific working method is as follows: When the paint roller 11 needs to be replaced, turn the knob 22, and the rotating column 20 will rotate accordingly, driving the second bevel gear 21 to rotate. Since the first bevel gear 19 meshes with the second bevel gear 21, the first bevel gear 19 starts to rotate, driving the bidirectional screw 18 to rotate. Since the limiting block 17 is threaded to both ends of the bidirectional screw 18, the limiting block 17 moves inward with the rotation of the bidirectional screw 18, so that the limiting block 17 is embedded in the connecting column 15, releasing the limitation of the limiting block 17 on the connecting column 15. At this time, the rotating column 14 can be pulled to move away from the paint roller 11, and the connecting column 15 can be pulled out from the paint roller 11, thereby completing the disassembly of the paint roller 11, which facilitates the replacement of the paint roller 11 and improves the practicality of the device.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
