Description

Technical Field

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

[0002] A roller coater is an automated coating device that uses rotating rollers (brushes) to evenly coat the surface of a workpiece (such as sheet metal, paper, metal sheet, plastic film, etc.) with coating materials such as paint, ink, and adhesives. Through mechanical transmission and structural design, it achieves continuous, efficient, and uniform transfer of coatings and is widely used in industries such as furniture manufacturing, building materials processing, printing and packaging, and metal surface treatment.

[0003] The width of existing roller coating machines is mostly non-adjustable. The non-adjustable roller width can only match the fixed size of the workpiece. If a workpiece with a smaller width needs to be processed, it will lead to paint waste. If a workpiece with a larger width needs to be processed, multiple coatings are required, which is not only inefficient, but may also result in uneven coating at the joints. Utility Model Content

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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an adjustable coating width roller coating machine, including a mounting frame 1, a connecting plate 2 fixedly welded to one side of the mounting frame 1, two sets of mounting plates 3 fixedly welded to the upper side of the mounting frame 1 and the connecting plate 2, a power shaft 4 rotatably mounted between the mounting plates 3, a motor 27 mounted on the outer flange of one side of the mounting plate 3, the power end of the motor 27 connected to the power shaft 4 by a coupling, a fixed roller 5 fixedly welded to the outer side of one side of the power shaft 4, the motor 27 drives the power shaft 4, which can drive the fixed roller 5 to rotate, realizing the coating operation, and several... The connecting roller 6, the fixed roller 5, and the connecting roller 6 are provided with an insertion groove 7 on one side. The fixed roller 5 and the connecting roller 6 are provided with four sets of follower grooves 8 that communicate with the insertion groove 7 on one side. The connecting roller 6 is fixedly welded to an insertion shaft 9 that matches the insertion groove 7 on the other side. The insertion shaft 9 is fixedly welded to four sets of follower blocks 10 that match the follower grooves 8 on the other side. By moving the connecting roller 6 along the power shaft 4, the insertion shaft 9 at one end of the connecting roller 6 is inserted into the insertion groove 7, thereby adjusting the coating width and inserting the follower blocks 10 into the follower grooves 8, ensuring that the fixed roller 5 can drive the connecting roller 6 to rotate.

[0023] A mounting groove 11 is provided on one side of the connecting roller 6, and a sealing ring 12 is fitted inside the mounting groove 11 to prevent paint from entering through the gap between the fixed roller 5 and the connecting roller 6, or the gap between the connecting rollers 6.

[0024] A mounting rail 13 is fixedly welded between two sets of mounting plates 3. Two sets of movable plates 15 are slidably installed inside the mounting rail 13. Two sets of rotating shafts 16 are rotatably installed in the middle of the movable plates 15. A baffle 17 is fixedly welded to one side of the rotating shaft 16. Several sets of fixing holes 14 are opened on the upper part of the mounting rail 13. A locking rod 20 that matches the fixing hole 14 is slidably installed inside the movable plate 15. A pulling plate 21 is fixedly welded to the upper part of the locking rod 20. By adjusting the position of the movable plate 15 along the mounting rail 13, the baffle 17 is opened by rotating the shaft 16, so that the baffle 17 can pass through the connecting roller 6. The baffle 17 returns to the vertical direction, so that the baffle 17 is tightly attached to one side of the connecting roller 6, preventing the insertion shaft 9 from disengaging from the insertion groove 7, and blocking the unused connecting roller 6 to prevent the connecting roller 6 from moving arbitrarily. The fixing hole 14 is set in the same position as the side of the connecting roller 6 after connection and the side where the connecting roller 6 is placed when not in use. The locking rod 20 is inserted into the fixing hole 14 to ensure that the baffle 17 can tightly restrict the position of the connecting roller 6.

[0025] A reversing gear 18 that meshes with each other is fixedly welded to the other side of the rotating shaft 16, so that when facing the rotating shaft 16 on one side, the baffles 17 on both sides can be opened at the same time, reducing the number of operation steps.

[0026] A torsion spring 19 is fixedly welded between the reversing gear 18 and the movable plate 15. The torsion spring 19 is sleeved on the outside of the rotating shaft 16. The torsion spring 19 pulls the baffle 17 to ensure that the baffle 17 can be in the vertical direction, preventing the baffle 17 from rotating arbitrarily and affecting the limiting effect.

[0027] A spring 22 is fixedly welded between the pull plate 21 and the moving plate 15. The spring 22 is sleeved on the outside of the locking rod 20. When the spring 22 is in the normal extension and contraction state, it can drive the pull plate 21 to move downward, thereby fixing the locking rod 20 in the fixing hole 14 and ensuring the stability of the locking rod 20.

[0028] An infusion pipe 23 is fixedly welded between the two mounting plates 3. Several sets of outlet pipes 24 are fixedly welded to the lower part of the infusion pipe 23, facing the fixed roller 5 and the connecting roller 6. The outlet pipes 24 are controlled by a solenoid valve. The infusion pipe 23 is connected to the outer paint tank and paint is delivered into the infusion pipe 23. The opening of the outlet pipe 24 is controlled by the solenoid valve, so that the opening of the corresponding outlet pipe 24 is controlled according to the number of connecting rollers 6 used, ensuring that the paint falls smoothly into the fixed roller 5 and the connecting roller 6, which facilitates the painting operation.

[0029] A collection box 25 is fixedly welded between the two mounting frames 1, facing the fixed roller 5 and the connecting roller 6, to ensure that excess paint can fall into the collection box 25 and collect the paint. Two sets of transmission belts 26 are fixedly installed between the two mounting frames 1 to facilitate the transportation of wooden boards and metal plates. The wooden boards and metal plates are moved by the transmission belts 26 on both sides and pass through the fixed roller 5 and the connecting roller 6 to realize the painting operation.

[0030] Working principle: In use, this utility model adjusts the brushing width by moving the connecting roller 6 along the power shaft 4, inserting the insertion shaft 9 at one end of the connecting roller 6 into the insertion groove 7, and inserting the follower block 10 into the follower groove 8, ensuring that the fixed roller 5 can drive the connecting roller 6 to rotate. By adjusting the position of the moving plate 15 along the mounting rail 13, the baffle 17 is opened by rotating the shaft 16, allowing the baffle 17 to pass through the connecting roller 6. The baffle 17 returns to the vertical direction under the pull of the torsion spring 19, thus opening the baffle 17. Closely attached to one side of the connecting roller 6, the locking rod 20 is inserted into the fixing hole 14 to ensure that the baffle 17 can tightly restrict the position of the connecting roller 6. The infusion pipe 23 is connected to the outer paint tank, and paint is delivered into the infusion pipe 23. The opening of the outlet pipe 24 is controlled by the solenoid valve, so that the opening of the corresponding outlet pipe 24 is controlled according to the number of connecting rollers 6 used, ensuring that the paint falls smoothly into the fixed roller 5 and the connecting roller 6. The wooden board and the metal plate are moved by the transmission belts 26 on both sides and pass through the fixed roller 5 and the connecting roller 6 to realize the painting operation.
