Description

Technical Field

[0001] This utility model relates to the field of sodium hypochlorite tube manufacturing technology, and in particular to a dip coating device for sodium hypochlorite tube manufacturing. Background Technology

[0002] A hypotube is a long metal tube with micro-engineered features throughout. It is a crucial component of catheters used in minimally invasive procedures, requiring the use of balloons and stents to open arterial blockages. The balloon portion of the catheter is attached to the distal end of the hypotube. The hypotube enters the body and pushes the balloon along the complex, winding blood vessel towards the site of the blockage. During this process, the hypotube must avoid kinking and ensure smooth passage within the body's structures. The manufacturing process of hypotubes often requires the use of dipping and coating equipment.

[0003] Patent CN219850417U discloses a dip-coating device for the production of sodium hypochlorite tubes. A column drives two fixed rings to rotate via multiple connecting plates. These two fixed rings, in turn, drive a fixed rod to rotate via multiple connecting rods. During this rotation, the sodium hypochlorite tubes are drawn into the dip-coating box for individual dip-coating, preventing poor coating results. Simultaneously, a rotating shaft drives a transmission shaft, which in turn drives a spiral auger. The spiral auger's rotation causes the dip-coating liquid to flow, ensuring uniform and efficient dip-coating of the sodium hypochlorite tubes. However, this dip-coating device can only coat one sodium hypochlorite tube at a time, and coating multiple groups of tubes takes a long time, thus reducing overall coating efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dip coating device for the production of sodium hypochlorite tubes. When the existing dip coating device for the production of sodium hypochlorite tubes is used, it can only dip coat one sodium hypochlorite tube at a time, and the time required to dip coat several groups of sodium hypochlorite tubes is long, thereby reducing the dip coating efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is a dipping and coating device for the production of sodium hypochlorite tubes, including a main body and a rotating disk located on the side wall of the main body. Several sets of tube winding columns are installed on one side of the rotating disk near the edge. One end of each set of tube winding columns is fixedly connected to a driven rod that penetrates the rotating disk. The other end of each set of driven rods is fastened to a connecting gear.

[0006] A second rotating shaft is provided through the middle of the rotating disk, and a toothed disk is fixedly connected to one end of the second rotating shaft. A movable ring is fixedly sleeved around the outer periphery of the rotating disk.

[0007] As a further embodiment of this utility model: a first motor is fixedly installed on the top side of the main body, the output end of the first motor is fixedly connected to a first rotating shaft that passes through the main body, the other end of the first rotating shaft is fixedly connected to a second motor, and the second motor is engaged with the rotating disk, and the movable ring is movably connected to the main body.

[0008] As a further embodiment of this utility model: the second rotating shaft passes through the rotating disk and is fixedly connected to the output end of the second motor. The gear disk meshes with several sets of connecting gears, and the several sets of connecting gears are evenly distributed at the edge of the rotating disk.

[0009] As a further embodiment of this utility model: a sliding ring disc is movably sleeved on the outer side of several groups of the winding column, four sets of connecting sliders are fixedly connected to the inner side of several groups of the sliding ring discs, a sliding inner disc is fixedly connected between the four sets of connecting sliders, a compression spring is fixedly connected to the inner side of several groups of the sliding inner discs, and a ring baffle is fixedly sleeved on the outer side of several groups of the sliding ring discs.

[0010] As a further embodiment of this utility model: the four sets of connecting sliders are equally spaced between the sliding ring disk and the sliding inner disk, and four sets of connecting slide openings are equally spaced through the several sets of winding columns, with the four sets of connecting sliders located on the inner side of the four sets of connecting slide openings respectively.

[0011] As a further embodiment of this utility model: the sliding inner disc is located inside the winding column, and one end of the compression spring is fixedly connected to the inner end of the winding column.

[0012] Compared with the prior art, the beneficial effects of this utility model include: by starting the first motor on the outside of the main body, the first rotating shaft is driven to rotate, thereby driving the second motor and the rotating disk to rotate together with the movable ring, and then driving several sets of tube columns to rotate around the first rotating shaft. At this time, several sets of sodium hypochlorite tubes pass through the immersion liquid inside the main body in sequence. Then, the second motor on the rotating disk is started to drive the second rotating shaft and the gear disk to rotate together, thereby driving several sets of driven rods to rotate through the meshing gear disk and connecting gear, and then driving several sets of tube columns to rotate individually, thus realizing the uniform immersion coating function of several sets of sodium hypochlorite tubes, and the immersion coating efficiency is high.

[0013] Compared with the prior art, the beneficial effects of this utility model include: firstly, several sets of sodium hypochlorite tubes are wound onto several sets of winding columns, and then the sliding inner disc is slid along the inner side of the winding column by compression spring. Thus, with the cooperation of four sets of connecting sliders and four sets of connecting sliding ports, the sliding ring disc is driven to slide along the outer side of the winding column until the sliding ring disc presses tightly against one end of the sodium hypochlorite tube, and the end is limited by the ring baffle. This allows for the placement of sodium hypochlorite tubes of different lengths and sizes, making it highly applicable. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1, please refer to Figures 1-4 A dipping device for producing sodium hypochlorite tubes includes a main body 1 and a rotating disk 5 located on the side wall of the main body 1. Several sets of tube winding columns 7 are installed near the edge of one side of the rotating disk 5. One end of each set of tube winding columns 7 is fixedly connected to a driven rod 10 that passes through the rotating disk 5. The other end of each set of driven rods 10 is fastened to a connecting gear 11. A second rotating shaft 8 is provided through the middle of the rotating disk 5. One end of the second rotating shaft 8 is fastened to a gear disk 9. A movable ring 6 is fixedly sleeved around the outer periphery of the rotating disk 5.

[0021] A first motor 2 is fixedly installed on the top side of the main body 1. The output end of the first motor 2 is fixedly connected to a first rotating shaft 3 that passes through the main body 1. The other end of the first rotating shaft 3 is fixedly connected to a second motor 4, and the second motor 4 is engaged with the rotating disk 5. The movable ring 6 is movably connected to the main body 1.

[0022] In this embodiment, the rotation of the rotating disk 5 is achieved through the cooperation of the first rotating shaft 3 and the movable ring 6.

[0023] The second rotating shaft 8 passes through the rotating disk 5 and is fixedly connected to the output end of the second motor 4. The gear disk 9 meshes with several sets of connecting gears 11, and the several sets of connecting gears 11 are evenly distributed at the edge of the rotating disk 5.

[0024] In this embodiment, the meshing action of the gear disc 9 and the connecting gear 11 enables the driven rod 10 and the tube column 7 to rotate together.

[0025] Specifically, by activating the first motor 2 on the outside of the main body 1, the first rotating shaft 3 is driven to rotate, which in turn drives the second motor 4 and the rotating disk 5 to rotate together with the movable ring 6. This, in turn, drives several sets of tube columns 7 to rotate around the first rotating shaft 3. At this time, several sets of sodium hypochlorite tubes pass through the immersion liquid inside the main body 1 in sequence. Then, the second motor 4 on the rotating disk 5 is activated, which drives the second rotating shaft 8 and the gear disk 9 to rotate together. This drives several sets of driven rods 10 to rotate through the meshing gear disk 9 and the connecting gear 11. This drives several sets of tube columns 7 to rotate individually, thus achieving the function of uniform immersion coating of several sets of sodium hypochlorite tubes with high immersion coating efficiency.

[0026] Example 2, please refer to Figures 1-4 A dipping device for producing sodium hypochlorite tubes includes several sets of sliding ring discs 12 movably sleeved on the outer side of the tube column 7, four sets of connecting sliders 13 fixedly connected to the inner side of the several sets of sliding ring discs 12, sliding inner discs 14 fixedly connected between the four sets of connecting sliders 13, compression springs 15 fixedly connected to the inner side of the several sets of sliding inner discs 14, and ring baffles 17 fixedly sleeved on the outer side of the several sets of sliding ring discs 12.

[0027] Four sets of connecting sliders 13 are evenly distributed between the sliding ring disk 12 and the sliding inner disk 14. Several sets of connecting slides 16 are evenly spaced through the winding column 7. The four sets of connecting sliders 13 are located inside the four sets of connecting slides 16.

[0028] In this embodiment, the sliding ring disk 12 moves along the winding tube column 7 through the cooperation of four sets of connecting sliders 13 and four sets of connecting sliding ports 16.

[0029] The sliding inner plate 14 is located inside the winding column 7, and one end of the compression spring 15 is fixedly connected to the inner end of the winding column 7.

[0030] In this embodiment, the compression spring 15 is used to allow the sliding inner disk 14 to move inside the tube column 7.

[0031] Specifically, several sets of sodium hypochlorite tubes are first wound onto several sets of winding columns 7. Then, the inner sliding disc 14 is slid along the inner side of the winding column 7 by the compression spring 15. With the cooperation of four sets of connecting sliders 13 and four sets of connecting sliding ports 16, the sliding ring disc 12 is driven to slide along the outer side of the winding column 7 until the sliding ring disc 12 presses tightly against one end of the sodium hypochlorite tube and limits its end by the ring baffle 17. This method can accommodate sodium hypochlorite tubes of different lengths and sizes, making it highly adaptable.
