Description

Technical Field

[0001] This utility model relates to the technical field of steel strip coating equipment, and in particular to a dual-position coating device for electrical steel strips that is easy to maintain. Background Technology

[0002] Steel strip, also known as strip steel, is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products. Electrical steel strip is a commonly used production steel strip. In some processing workshops, different types of mechanical products need to be processed and produced in batches. Therefore, it is necessary to coat the electrical steel strip with appropriate coatings according to process requirements.

[0003] Steel strip is usually supplied in rolls. When coating steel strip, a steel strip unpacking device is needed to unroll the rolled steel strip. Then, the movable end of the steel strip is passed through the coating machine. A traction device is then used to pull the movable end of the steel strip so that the steel strip can pass through the coating machine at a uniform speed and be coated with paint as it passes through the coating machine.

[0004] During long-term production, coating machines inevitably experience malfunctions and stop operating, requiring maintenance before work can resume. However, the causes of coating machine malfunctions are varied, and maintenance can be lengthy. Prolonged downtime can affect the coating efficiency of steel strips. Utility Model Content

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a dual-position coating device for electrical steel strips that facilitates maintenance, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a base 1, which has a working area 11 and two maintenance areas 12 spaced apart along a direction perpendicular to the steel belt transport direction, with the working area 11 located between the two maintenance areas 12. Two coating machine bodies 2 are horizontally and linearly slidably mounted on the base 1, and a first driving component 3 is installed on the base 1 to drive the two coating machine bodies 2 to move. Each of the two coating machine bodies 2 is provided with a positioning part, and positioning components 5 for connecting and cooperating with the positioning parts are installed on the base 1 in the working area 11 and each maintenance area 12.

[0021] In this embodiment, one coating machine body 2 is located in the working area 11 for steel strip coating, while another coating machine body 2 is located in one of the maintenance areas 12 as a backup. When the coating machine body 2 in the working area 11 malfunctions, it can be moved out by the first driving component 3, and the backup coating machine body 2 can be moved into the working area 11 to ensure that the steel strip coating operation can be quickly resumed. This has the effect of improving the efficiency of steel strip coating.

[0022] Reference Figure 4 The positioning part includes a positioning column 4 that is vertically slidably mounted on the coating machine body 2. The positioning assembly 5 includes a positioning cylinder 51 and a pressure block 52. The coating machine body 2 is provided with an elastic element 7 for driving the positioning column 4 to move away from the positioning cylinder 51. The base 1 is equipped with a second driving element 6 for driving the pressure block 52 to move vertically downward to abut the top of the positioning column 4 and overcome the elastic force of the elastic element 7 to move the positioning column 4.

[0023] In this embodiment, the coating machine body 2 can be moved by the first driving member 3 so that the positioning post 4 on the coating machine body 2 can be aligned with the positioning cylinder 51; then the pressure block 52 can be driven down by the second driving member 6 so that the positioning post 4 can be moved down and inserted into the positioning cylinder 51, thereby achieving the purpose of positioning the coating machine body 2.

[0024] Specifically, the positioning post 4 includes a first sliding post 41 and a second sliding post 42 coaxially welded and fixed. The outer diameter of the first sliding post 41 is larger than the outer diameter of the second sliding post 42. The coating machine body 2 has a first sliding groove 21 for the first sliding post 41 to slide. A through hole for the second sliding post 42 to pass through is opened in the bottom wall of the first sliding groove 21. The elastic element 7 includes a spring, which is disposed in the first sliding groove 21. The two ends of the spring abut against the bottom of the first sliding post 41 and the bottom wall of the first sliding groove 21, respectively.

[0025] In this embodiment, after the pressure block 52 moves upward and releases the positioning post 4, the positioning post 4 can be driven upward and away from the positioning cylinder 51 by the elastic force of the spring.

[0026] To prevent the two coating machine bodies 2 from colliding and being damaged during movement, a flexible layer 8 is provided on the side of each coating machine body 2 that is close to each other. The flexible layer 8 can be made of rubber.

[0027] Furthermore, a slide block 9 is slidably disposed on the base 1 along the moving direction of the coating machine body 2, and a second slide groove 13 is provided on the top of the base 1 for the slide block 9 to move. The coating machine body 2 is slidably connected to the base 1 via the slide block 9, and a roller 10 is rotatably disposed at the bottom of the slide block 9 for rolling contact with the inner bottom wall of the second slide groove 13.

[0028] In this embodiment, the resistance experienced by the coating machine body 2 during movement can be reduced by using the slide 9 and the roller 10.

[0029] Furthermore, a connector 20 is provided between the coating machine body 2 and the base 1. The connector 20 includes multiple connecting bolts 201. The base 1 has multiple threaded holes of a size adapted to the connecting bolts 201 located in the working area 11 and the maintenance area 12. The bottom of the coating machine body 2 has multiple through holes for the connecting bolts 201 to pass through. After the multiple connecting bolts 201 pass through the through holes, they are threaded into the multiple threaded holes.

[0030] When the positioning pin 4 is inserted into the corresponding positioning cylinder 51, multiple connecting bolts 201 are passed through the through hole and threaded into multiple threaded holes, which can fix the coating machine body 2 and further improve the installation stability of the coating machine body 2.

[0031] In this embodiment, the first driving component 3 includes two drive motors and two screws. The two screws are parallel to the moving direction of the coating machine body 2 and are rotatably disposed in the second slide groove 13. The two coating machine bodies 2 are respectively threadedly connected to the two screws, and the output shafts of the two drive motors are respectively drivenly connected to the two screws. The second slide groove 13 is also provided with a guide rod parallel to the screws, and the guide rod moves through the two coating machine bodies 2.

[0032] The second driving component 6 includes a driving cylinder, which is mounted on the base 1. The piston rod of the driving cylinder is vertically downward and bolted to the pressure block 52.

[0033] The implementation principle of the dual-position coating device for electrical steel strips, which facilitates maintenance, according to an embodiment of this application, is as follows: one coating machine body 2 is located in the working area 11 for steel strip coating, while another coating machine body 2 is located in one of the maintenance areas 12 as a backup. When the coating machine body 2 in the working area 11 malfunctions, it can be moved out by the first driving component 3, and the backup coating machine body 2 can be moved into the working area 11 to ensure that the steel strip coating operation can be quickly resumed. This has the effect of improving the steel strip coating efficiency.
