Description

Technical Field

[0001] This utility model relates to the field of radio frequency closed conduit manufacturing technology, and in particular to a coating device. Background Technology

[0002] A medical catheter is a hollow catheter that can be inserted into human tubes, cavities, and blood vessels. Depending on the patient's actual treatment needs, the surface or inner lumen of a medical catheter may be endowed with different functionalities such as antibacterial, hydrophobic, hydrophilic, friction-resistant, and corrosion-resistant properties. These functionalities are mainly achieved through medical coatings. Radiofrequency closure catheters are medical devices used to treat diseases such as varicose veins. Their core function is to close veins using radiofrequency energy.

[0003] Chinese patent document CN118577439B discloses a dual-coating device and method for the surface and lumen of a medical catheter. The dual-coating device includes a chassis with a control panel on one side. Inside the chassis, from top to bottom, are a suction / blowing device, a catheter mounting device, a curing device, and an immersion / recovery device. The catheter mounting device includes a metal carrier plate, a support platform, and coating components. The suction / blowing device includes a ventilation device, a lifting device, and an anti-over-suction device. The curing device includes a curing chamber fixedly mounted on the chassis. At least one side of the curing chamber has an infrared heating lamp, and at least one side also has a heat dissipation device. The immersion / recovery device includes a liquid storage tank located within a recovery tank. The dual-coating device for the surface and lumen of the medical catheter in this application effectively solves the problem of dual-coating of the surface and lumen of medical catheters and reduces the risk of the lumen being blocked by the coating liquid after coating.

[0004] The existing technology has the following problems: The coating device places the conduit after it has been soaked in the coating solution directly into the curing chamber, and the curing chamber and the soaking tank are arranged one above the other. This causes some of the coating solution to drip into the curing chamber during the curing process, which affects cleaning. Alternatively, some of the coating solution may drip onto the infrared lamp tube, and after drying, some solid impurities will adhere to the outside of the lamp tube, affecting the light emission ability of the dried lamp tube.

[0005] This invention provides a coating apparatus to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A coating apparatus includes a frame, a moving mechanism movably mounted on the rear side of the front wall of the frame, a drying mechanism movably mounted on the rear side of the moving mechanism, a lifting mechanism movably mounted on the rear side of the frame, a placement mechanism movably mounted on the front side of the lifting mechanism, and a liquid storage tank fixedly connected to the bottom inner side of the frame. The drying mechanism includes a drying chamber, with several rectangular infrared lamps fixedly connected to the front and rear sides of the inner side of the drying chamber. Two baffles are fixedly connected to the inner side of the drying chamber, with the baffles located above the infrared lamps.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-6 As shown, a coating device includes a frame 1, a moving mechanism 2 is movably mounted on the rear side of the front wall of the frame 1, a drying mechanism 3 is movably mounted on the rear side of the moving mechanism 2, a lifting mechanism 4 is movably mounted on the rear side of the frame 1, a placement mechanism 5 is movably mounted on the front side of the lifting mechanism 4, and a liquid storage tank 6 is fixedly connected to the bottom inner side of the frame 1. The drying mechanism 3 includes a drying chamber 31. Several rectangular infrared lamps 32 are fixedly connected to the front and rear sides of the inner side of the drying chamber 31. Two baffles 33 are fixedly connected to the inner side of the drying chamber 31, and the baffles 33 are located on the upper side of the infrared lamps 32. A flexible pad 34 is attached to the bottom of the inner side of the drying chamber 31. Heat dissipation components 35 are fixedly connected to the left and right sides of the drying chamber 31.

[0019] It should be noted that the structural design of the moving mechanism 2, the lifting mechanism 4 and the liquid storage tank 6 is consistent with the components with the same function in the reference case, which is existing technology and will not be described in detail here. The shielding plate 33 is used to shield the infrared lamp tube 32, and the flexible pad 34 is used to reduce the height of the dripping coating liquid splashing. The flexible pad 34 can be made of sponge pad or other flexible materials.

[0020] like Figure 3 As shown, the heat dissipation assembly 35 includes a connecting pipe 351. The side of the connecting pipe 351 closest to the flexible pad 34 is fixedly connected to the left and right sides of the drying chamber 31. A cooling fan 352 is fixedly connected to the inside of the connecting pipe 351. An installation box 353 is fixedly connected to the left and right sides of the inside of the drying chamber 31. An absorbent cotton 354 is movably sleeved on the inside of the installation box 353.

[0021] It should be noted that the absorbent cotton 354 is used to absorb the evaporated coating liquid and prevent it from falling onto the blades of the cooling fan 352. The connecting pipe 351 is equipped with a humidity sensor to detect the humidity inside the connecting pipe 351, so as to detect whether the cooling fan 352 is saturated, or whether a large amount of dried coating liquid adhering to the absorbent cotton 354 has a significant impact on the adsorption capacity of the absorbent cotton 354.

[0022] like Figure 2 As shown, the upper side of the two baffles 33 and the bottom of the inner side of the drying box 31 are provided with a hydrophobic layer, and the lower inner surface of the drying box 31 is inclined to the lower left.

[0023] It should be noted that the hydrophobic layer is used to prevent the coating liquid from adhering to the baffle plate 33 and the drying box 31. The structural design of the drying box 31 allows the coating liquid falling into the drying box 31 to automatically flow to the left and then be discharged from the drying box 31.

[0024] like Figures 4-6 As shown, the mounting mechanism 5 includes a connecting frame 51. Two anti-over-thin components 52 are movably mounted on the upper side of the connecting frame 51, distributed front to back. A fixing frame 53 is fixedly connected to the lower side of the connecting frame 51. A connecting plate 54 is rotatably connected to the lower side of the fixing frame 53. Two shock-absorbing seats 55 are fixedly connected to the lower side of the fixing frame 53, distributed left to right. A vibration motor 56 is provided between the lower side of the two shock-absorbing seats 55 and the upper side of the connecting plate 54.

[0025] It should be noted that the structure of the anti-excessive fineness component 52 is consistent with the structure of the component with the same function in the reference case. Since it is existing technology, it will not be described in detail here. After the conduit is coated, the vibration motor 56 drives the connecting plate 54 to vibrate, shaking off the excess coating liquid. The shock absorber 55 reduces the vibration generated by the vibration motor 56 and transmits it to the upper side.

[0026] like Figure 5 , Figure 6 As shown, four rectangularly distributed first telescopic rods 59 are fixedly connected to the upper side of the connecting plate 54. Each of the four first telescopic rods 59 is fixedly connected to a sleeve 58 on the side away from each other. A mounting plate 57 is movably sleeved on the inner side of the sleeve 58.

[0027] It should be noted that the first telescopic rod 59 is an electric push rod that can move the clamp 58. When the clamp 58 moves, it can fix the four corners of the mounting plate 57, thereby allowing the mounting plate 57 to be quickly installed and removed, avoiding direct fixation on the connecting plate 54, which would consume a lot of time when transferring the conduit.

[0028] like Figure 6 As shown, three second telescopic rods 510 arranged in a ring are fixedly connected to the lower side of the fixing frame 53.

[0029] It should be noted that the second telescopic rod 510 is an electric push rod. The second telescopic rod 510 can control its own length, thereby stabilizing the state of the connecting plate 54 after it vibrates.

[0030] like Figure 6 As shown, a rubber pad is fixedly connected to the upper side of the mounting plate 57, and four rectangular positioning holes 511 are provided on the lower side of the connecting plate 54.

[0031] It should be noted that the mounting plate 57 is provided with positioning posts corresponding to the positioning holes 511, which can facilitate the positioning of the mounting plate 57. The rubber pad is used to fill the gap between the mounting plate 57 and the connecting plate 54 to prevent the positioning holes 511 from moving. The anti-over-thin component 52 is connected to the mounting plate 57 by means of a pipe. Due to the presence of the rubber pad, the mounting plate 57 and the pipe can be sealed, which facilitates the assembly of the mounting plate 57.

[0032] The working principle of this utility model is as follows: First, the baffle plate 33 is used to shield the infrared lamp tube 32. The flexible pad 34 is used to reduce the splash height of the dripping coating liquid. The flexible pad 34 can be made of sponge or other flexible materials. The absorbent cotton 354 is used to absorb the evaporated coating liquid and prevent it from falling onto the blades of the cooling fan 352. A humidity sensor is installed in the connecting pipe 351 to detect the humidity inside the connecting pipe 351, so as to detect whether the cooling fan 352 is saturated, or whether a large amount of dried coating liquid adhering to the absorbent cotton 354 has a significant impact on the adsorption capacity of the absorbent cotton 354. The hydrophobic layer is used to prevent the coating liquid from adhering to the baffle plate 33 and the drying box 31. The structure of the drying box 31 allows the coating liquid falling into the drying box 31 to automatically flow to the left and then be discharged from the drying box 31. Through the shielding of the baffle plate 33 and the receiving of the flexible pad 34, the dripping coating liquid can be prevented from contacting the infrared lamp tube 32 as much as possible, and is automatically collected by the structure of the drying box 31. The system incorporates absorbent cotton 354 to absorb the evaporated coating liquid vapor, preventing it from adhering to the blades of the cooling fan 352, thus improving maintenance convenience and reducing maintenance costs. Finally, the structure of the anti-excessive coating component 52 is consistent with the structure of a component with the same function in the reference case, and is therefore not described in detail here as it is existing technology. After the conduit is coated, the vibration motor 56 drives the connecting plate 54 to vibrate, shaking off excess coating liquid. The shock absorber 55 reduces the upward transmission of vibration generated by the vibration motor 56. The second telescopic rod 510 is an electric push rod; its length can be controlled, thereby stabilizing the connecting plate 54 after vibration. The vibration motor 56 vibrates the connecting plate 54 after coating the conduit, causing excess coating liquid to be shaken off. Subsequently, the second telescopic rod 510 extends to stabilize the connecting plate 54, preventing it from moving and avoiding excessive coating liquid dripping, which could affect the surrounding environment and reduce coating liquid waste, thus lowering maintenance costs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
