Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment manufacturing, in particular to a movable protective device for a roller coating machine. Background Art

[0002] With the development of plate and strip coating technology, the use of roller coaters is increasing, and the demand for roller coaters' coating effects is also gradually increasing. When the plate and strip pass through the support roller, the residual coating liquid on the roller surface will flow along the roller end to the shaft head, and then flow into the linear guide. In addition, some of the coating liquid on the roller end will drip onto the material tray and the archway, and the dripping coating liquid will splash onto the linear guide. These situations will affect the running smoothness and accuracy of the linear guide, and thus have a great impact on the quality of plate and strip coating. At present, roller coating equipment either has no protective device, or the protective device is fixed and cannot fully protect the linear guide as the linear guide moves. These problems will lead to the following defects in the equipment:

[0003] 1. As the coating liquid accumulates on the linear guide rail, it will hinder the operation of the linear guide rail and cause its operation to be blocked;

[0004] 2. If the running accuracy of the linear guide rail does not meet the standard requirements, it will affect the coating quality of the plate and strip, and then affect the required thickness and uniformity of the plate and strip coating. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a movable protective device for a roller coater so that the linear guide rail and the slider can be fully protected in static and dynamic conditions.

[0006] In order to achieve the above-mentioned purpose of the invention, the protective device of the roller coater of the present invention is installed on both sides of the bearing seat by screws. The protective device protects the entire linear guide rail and the slider. The protective device can move with the up and down movement of the bearing seat and can move with the movement of the roller.

[0007] Furthermore, a gap is provided above the frame of the roller coating machine to enable the protective device to move to the top of the frame.

[0008] Furthermore, the bearing seats on both sides of the roller are slidably connected to the linear guide rails through sliders, the linear guide rails are vertically connected to the frame through screws, and the bearing seats move up and down with the linear guide rails.

[0009] Furthermore, the bearing seat is connected to the top rod end of the oil cylinder, and the cylinder barrel end of the oil cylinder is fixed to both sides of the frame of the roller coater through a pin shaft and a pressure block; the top rod of the oil cylinder moves, causing the bearing seats on both sides of the roller to rise and fall simultaneously.

[0010] Furthermore, a limit block is provided above the linear guide rail.

[0011] Furthermore, the roller is mounted on a bearing seat via a bearing, and the roller can be raised and lowered by the up and down movement of the bearing seat.

[0012] Compared with the prior art, the protective device of the utility model will not fail to provide adequate protection due to the movement of the linear guide rail. No matter the linear guide rail is in a working state or a moving state, it can provide good protection for the linear guide rail, so that the linear guide rail and the slider will not be affected by the coating liquid dripping from the end face of the roller when it splashes during the movement process; at the same time, the protective device can move with the movement of the roller, and will protect the coating liquid flowing out from the end face of the roller, so as to ensure that the protective device can fully play its role and its protective effect will not be reduced due to changes in the position of the roller.

[0017] like Figure 1 、 Figure 2 、 Figure 3 As shown, the roller 4 of the present invention is installed on the bearing seat 5 through bearings 10, and the bearing seats 5 on both sides of the roller 4 are slidably connected to the linear guide 2 through sliders 3. The linear guide 2 is vertically connected to the frame 6 by screws, and the bearing seat 5 moves up and down with the linear guide 2; the cylinder 8 provides power for the movement of the bearing seat 5, and the bearing seat 5 is moved to the required position by the lifting of the top rod of the cylinder 8. The bearing seat 5 is connected to the top rod end of the cylinder 8, and the cylinder end of the cylinder 8 is fixed to the frame 6 of the roller coater through a pin 11 and a pressure block 12. The movement of the top rod of the cylinder 8 causes the bearing seats 5 on both sides of the roller 4 to be lifted and lowered simultaneously on the linear guide 2, thereby making the roller 4 rise and fall with the up and down movement of the bearing seat 5 and ensuring the parallelism of the roller 4; a limit block 9 is provided above the linear guide 2 to ensure that the cylinder 8 can continue to exert force when it reaches the upper limit.

[0018] The protective device 1 of the roller coating machine is a plate-shaped structure, consisting of plate 13 and plate 2 14.， Plate 1 13 and plate 2 14 of the roller coater's protective device 1 are screwed to either side of the bearing seat 5. The protective device 1 protects the entire guide rail 2 and slider 3, and can move with the up and down movement of the bearing seat 5 and with the movement of the roller 4. A notch 7 is provided above the frame 6 of the roller coater, enabling the protective device 1 to be moved above the frame 6, thereby ensuring that the up and down movement of the protective device 1 is not obstructed. The protective device 1 prevents the linear guide rail 2 and slider 3 from being affected by splashes of coating liquid dripping from the end face of the roller 4 during movement. At the same time, the protective device 1 protects the coating liquid from flowing out of the end face of the roller 4. The protective device 1 can move with the movement of the roller 4 to ensure that the protective device 1 can fully function and its protective effect is not reduced due to changes in the position of the roller 4.

[0019] The protective device 1 of the present invention will not cause the situation where protection is not in place as the linear guide rail 2 moves. No matter the linear guide rail 2 is in a working state or a moving state, it can provide good protection effect.
