Description
Technical Field
[0001] This utility model relates to the field of nuclear magnetic resonance instrument manufacturing technology, specifically an electromagnetic shielding coating spraying device. Background Technology
[0002] In the production of nuclear magnetic resonance (NMR) instruments, the fiberglass cylinder is a key component. The inner wall of the fiberglass cylinder needs to be coated with an electromagnetic shielding coating to reduce the impact of external electromagnetic interference on the instrument's performance. A good electromagnetic shielding coating can not only effectively isolate complex external electromagnetic signals, but also prevent the leakage of electromagnetic radiation generated by the instrument itself, avoid interference with surrounding electronic equipment, and ensure the clarity and accuracy of NMR imaging.
[0003] In existing technologies, the electromagnetic shielding coating is mostly applied to the inner wall of FRP cylinders by manually inserting a handheld spray gun. This method is inconvenient to operate, difficult to carry out, and time-consuming and labor-intensive, which seriously affects the spraying efficiency. Furthermore, the limited field of vision when observing the pipeline from the outside results in low spraying accuracy, uneven and incomplete spraying, and the coating effect cannot be guaranteed. In addition, dust on the surface of the FRP cylinder will seriously affect the adhesion of the coating and reduce the electromagnetic shielding performance.
[0004] Based on this, an electromagnetic shielding coating spraying device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] In one embodiment, such as Figures 1-4As shown, an electromagnetic shielding coating spraying device includes a support 100, on which four support wheels 101 are provided. A fiberglass cylinder 200 is mounted on each of the four support wheels 101. A support and positioning mechanism is provided within the fiberglass cylinder 200. One end of the support and positioning mechanism is connected to a coating supply component via a pipe 300. A winding and rewinding component is provided on the support 100. A rotary spraying module is located at the end of the support and positioning mechanism away from the pipe 300. The fiberglass cylinder 200 is suspended between the four support wheels 101 and placed within the fiberglass cylinder 200 for support and fixation. The rotary spraying module performs spraying operations on the fiberglass cylinder 200. The winding and rewinding component can prevent the pipe 300 from interfering with the spraying process.
[0025] In this embodiment, as Figure 2 and Figure 3 As shown, the support and positioning mechanism includes a fixed tube 401, one end of which is fixedly connected to a pipe 300. The other end of the fixed tube 401 is fixedly connected to three rotating seats 402. A rotating tube 403 is rotatably connected to the outer end of the fixed tube 401. A moving ring 404 is threadedly connected to the end of the rotating tube 403 away from the rotating seats 402. Three rotating seats 405 are fixedly connected to the outer end of the moving ring 404. Two rotating rods 406 are rotatably connected to the rotating seats 402. Two rotating rods 407 are rotatably connected to the rotating seats 405. The rotating rods 406 and 407 are rotatably connected. One end of a connecting rod 408 is rotatably connected to the rotating rod 406. A sliding shaft 410 is fixedly connected to the rotating rod 407 and slidably connected in the sliding groove 409. The rotating tube 401... 3. Gear 411 is fixedly connected to the upper part of the frame. Gear 411 meshes with gear 412. Gear 412 is fixedly connected to the output shaft of motor 413. Motor 413 is fixedly connected to the fixed tube 401. A moving unit is provided on the connecting rod 408. When the fixed tube 401 is placed in the fiberglass cylinder 200, motor 413 drives gear 412 to rotate. Gear 412 drives gear 411 to rotate. Gear 411 drives rotating tube 403 to rotate. Since rotating tube 403 is threadedly connected to moving ring 404, moving ring 404 moves towards rotating seat 402. The distance between rotating seat 402 and rotating seat 405 is shortened. Through rotating rod 406 and rotating rod 407, connecting rod 408 moves towards the inner wall of fiberglass cylinder 200, driving the moving unit to support the inner wall of fiberglass cylinder 200, and supporting the rotary spraying module at the center position inside fiberglass cylinder 200.
[0026] In one embodiment, such as Figure 2 and Figure 3As shown, the moving unit includes a first connecting frame 501, which is fixedly connected to one end of a connecting rod 408. A drive wheel 502 is rotatably connected to the first connecting frame 501. The drive wheel 502 is fixedly connected to the output shaft of a second motor 503. The second motor 503 is fixedly connected to the first connecting frame 501. A second connecting frame 504 is fixedly connected to the end of the connecting rod 408 away from the first connecting frame 501. A driven wheel 505 is rotatably connected to the second connecting frame 504. The drive wheel 502 and the driven wheel 505 are supported on the inner wall of the fiberglass cylinder 200. The second motor 503 drives the drive wheel 502 to rotate, thereby moving the device.
[0027] In one embodiment, such as Figure 2 and Figure 3 As shown, the rotary spraying module includes a rotary tube 601, which is rotatably connected to the end of a fixed tube 401 away from the pipe 300. The rotary tube 601 is fixedly connected to one end of an L-shaped spray pipe 602, and the other end of the L-shaped spray pipe 602 is fixedly connected to a spray head 603. A gear 3 604 is fixedly connected to the outer end of the rotary tube 601. The gear 3 604 meshes with a gear 4 605. The gear 4 605 is fixedly connected to the output shaft of a motor 3 606. Fixedly connected to the fixed pipe 401, during spraying, motor 3 606 drives gear 4 605 to rotate, gear 4 605 drives gear 3 604 to rotate, gear 3 604 drives rotating pipe 601 to rotate, rotating pipe 601 drives L-shaped spray nozzle 602 to rotate. Paint enters the fixed pipe 401 through pipe 300, enters the rotating pipe 601 through the fixed pipe 401, and then enters the L-shaped spray nozzle 602 through the rotating pipe 601, and is sprayed out through nozzle 603. After rotating one revolution, it moves to the next position to continue spraying.
[0028] In one embodiment, such as Figure 3 As shown, three telescopic rods 701 are fixedly connected to the outer end of the rotating tube 601, and cleaning brushes 702 are fixedly connected to the output ends of the three telescopic rods 701. Before spraying, the telescopic rods 701 extend out of the output rods, causing the cleaning brushes 702 to contact the inner wall of the fiberglass cylinder 200. Before spraying, the cleaning brushes 702 rotate with the rotating tube 601 to clean the inner wall of the fiberglass cylinder 200.
[0029] In one embodiment, such as Figure 1 and Figure 4As shown, the sorting component includes a sorting roller 801. One end of the sorting roller 801 is rotatably connected to a fixed plate 802, and the other end of the sorting roller 801 is rotatably connected to a rotating shell 805. One end of a spring 803 is fixedly connected to the inner wall of the rotating shell 805, and the other end of the spring 803 is fixedly connected to a fixed shaft 804. The fixed shaft 804 is fixedly connected to the sorting roller 801. A pipe 300 is wound around the outer end of the sorting roller 801. When the pipe 300 is pulled out, it will drive the sorting roller 801 to rotate, thereby compressing the spring 803. The spring 803 gives the sorting roller 801 a restoring force. When the pipe 300 is released, it will rewind around the outer end of the sorting roller 801.
[0030] In one embodiment, such as Figure 1 and Figure 4 As shown, the coating supply component includes a water pump 901. The output end of the water pump 901 is fixedly connected to the pipe 300, and the input end of the water pump 901 is connected to the storage tank 902. The water pump 901 draws the coating in the storage tank 902 into the pipe 300, enters the rotating pipe 601 through the fixed pipe 401, and then enters the L-shaped spray pipe 602 through the rotating pipe 601, and is sprayed out through the nozzle 603.
[0031] In one embodiment, such as Figure 1 As shown, the lower end of the support 100 is fixedly connected to four casters 102, which facilitates moving the device to a designated position and reduces the labor intensity of workers.
[0032] The above embodiment discloses an electromagnetic shielding coating spraying device, in which a fiberglass cylinder 200 is suspended between four support wheels 101 and placed. A fixed tube 401 is placed inside the fiberglass cylinder 200. A motor 413 drives a gear 412 to rotate, which in turn drives a gear 411 to rotate. The gear 411 then drives a rotating tube 403 to rotate. Since the rotating tube 403 is threadedly connected to a moving ring 404, the moving ring 404 moves towards a rotating seat 402, shortening the distance between the rotating seat 402 and the rotating seat 405. This causes the connecting rod 408 to move towards the inner wall of the fiberglass cylinder 200 via rotating rods 406 and 407, thus supporting the drive wheel 502 and the driven wheel 505 inside the fiberglass cylinder 200. On the wall, motor 2 503 drives the drive wheel 502 to rotate, thereby moving the device. Before spraying, motor 3 606 drives gear 4 605 to rotate, gear 4 605 drives gear 3 604 to rotate, gear 3 604 drives the rotating tube 601 to rotate. The cleaning brush 702 rotates with the rotating tube 601, first cleaning the inner wall of the fiberglass cylinder 200. After cleaning, the water pump 901 draws the paint in the storage tank 902 into the pipe 300, enters the rotating tube 601 through the fixed pipe 401, and then enters the L-shaped spray pipe 602 through the rotating tube 601, and is sprayed out through the nozzle 603. After rotating once, it moves to the next position to continue spraying, increasing the efficiency of spraying. The operation is simple and convenient, saving time and effort, and eliminating the need for manual cleaning and spraying.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
