Description

Technical Field

[0001] The utility model relates to the technical field of braiding machines, in particular to heat dissipation equipment for a catheter braiding machine. Background Art

[0002] The woven layer of balloon dilatation catheters commonly used in cardiovascular interventional treatments is usually made of stainless steel wire, while some catheters used for infusion or drainage are usually woven with polymer materials such as polyurethane or polyamide.

[0003] In order to improve braiding efficiency, braiding machines usually run at a higher speed. The rapid reciprocating motion and frequent movements of the components will lead to rapid conversion and accumulation of energy, thereby generating a large amount of heat. In the process of braiding metal catheters and polymer catheters, the metal and polymer materials will experience deformations such as stretching, bending and torsion, and there will be more friction and generate more heat. Due to the poor heat dissipation of the braiding machine itself, the heat of the braided material is more difficult to dissipate through the braiding machine, which can easily cause the metal to overheat and change its strength and hardness. For polymer materials, softening, deformation and static electricity are prone to occur, affecting the quality and performance of the catheter.

[0004] Therefore, those skilled in the art provide a heat dissipation device for a catheter braiding machine to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to provide a heat dissipation device for a catheter braiding machine to solve the following technical problems:

[0006] How to improve the heat dissipation efficiency of the braiding machine, improve the quality of catheter braiding, and ensure the accuracy and consistency of braiding.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A heat dissipation device for a catheter braiding machine comprises a braiding mechanism, a transmission component is connected to the bottom of the braiding mechanism, and a heat dissipation mechanism is fixedly connected to the transmission component;

[0009] The heat dissipation mechanism includes a protective cover, the braided mechanism is located in the middle of the protective cover, an upper cavity and a lower cavity are respectively opened inside the protective cover, and the lower cavity is used to place cold water;

[0010] The outer side of the protective cover is connected to a plurality of fans, the inner side of the protective cover is provided with a ventilation mesh opening, and the upper cavity is connected to the fans and the ventilation mesh opening;

[0011] A plurality of water pipes are connected between the upper cavity and the lower cavity, and one end of the water pipe extends into the upper cavity and is fixedly connected with an atomizing nozzle.

[0012] Furthermore, the plurality of fans and water pipes are arranged in an interlaced manner, and the outer sides of the plurality of water pipes are fixedly connected with electromagnetic valves.

[0013] Furthermore, a water pump is fixedly connected to one side above the transmission component, an input end of the water pump is connected to a cold water tank, the cold water tank is placed below the transmission component, and an output end of the water pump is connected to the lower cavity.

[0014] Furthermore, a heat-conducting component is fixedly connected between the transmission component and the cold water tank, and the heat-conducting component includes a heat-conducting plate and a heat sink. The heat-conducting plate is fixedly connected to the inner bottom of the transmission component, and the heat sink is fixedly connected to the bottom of the heat-conducting plate. The heat sink extends out of the transmission component and into the interior of the cold water tank, and multiple heat sinks are arranged at intervals.

[0018] Beneficial effects of the utility model:

[0019] (1) The utility model is provided with a heat dissipation mechanism. When the knitting machine is working, the water pump fills the water in the cold water tank into the lower cavity of the protective cover, and then the cold water flows into the water pipe and is sprayed out through the atomizing nozzle. At the same time, multiple fans absorb external wind and gather it into the upper cavity, and then blow it out from the ventilation mesh. At this time, the atomized water sprayed by the atomizing nozzle can be blown onto the knitting mechanism together with the wind direction, which can effectively dissipate the heat of the high-speed knitting mechanism and the knitting wire, which is beneficial to prolonging the service life of the knitting machine.

At the same time, it can maintain the physical properties of the woven material, which is conducive to ensuring the accuracy and consistency of the weaving. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Please see attached Figure 1-5 A heat dissipation device for a catheter braiding machine in an embodiment of the utility model comprises a braiding mechanism 1, a transmission component 3 is connected to the bottom of the braiding mechanism 1, the transmission component 3 is used for the braiding mechanism 1 to run and braid, a heat dissipation mechanism 2 is fixedly connected to the driving transmission component 3, and the heat dissipation mechanism 2 can dissipate heat for the braiding mechanism 1;

[0031] The heat dissipation mechanism 2 includes a protective cover 22, the braiding mechanism 1 is located in the middle of the protective cover 22, and an upper cavity 26 and a lower cavity 29 are respectively opened inside the protective cover 22, and the lower cavity 29 is used to place cold water;

[0032] A plurality of fans 24 are connected to the outside of the protective cover 22, a ventilation mesh opening 21 is provided on the inside of the protective cover 22, and an upper cavity 26 is connected to the fans 24 and the ventilation mesh opening 21;

[0033] A plurality of water pipes 23 are connected between the upper cavity 26 and the lower cavity 29. One end of the water pipe 23 extends into the upper cavity 26 and is fixedly connected to an atomizing nozzle 28. The output end of the atomizing nozzle 28 faces the ventilation mesh port 21. A plurality of fans 24 absorb external wind and converge it into the upper cavity 26, and then blow it out from the ventilation mesh port 21 to perform air cooling and heat dissipation on the weaving mechanism 1. At the same time, the atomized water sprayed by the atomizing nozzle 28 can diffuse along the wind direction and be blown out to the weaving mechanism 1 together. The wind can reduce the temperature of the sprayed atomized water, so that water cooling and heat dissipation can be performed at the same time as air cooling and heat dissipation, which is beneficial to The cooling of the braiding mechanism 1 is accelerated, and the atomized water blown out at the same time can be scattered onto the braiding wire. If the braiding wire is made of metal, the sprayed atomized water can effectively reduce the temperature of the metal to prevent its performance changes due to overheating, such as reduced strength and hardness changes. If the braiding wire is made of polymer material, the sprayed atomized water can help control the temperature and keep the performance of the material stable. During the weaving process, polymer materials are prone to static electricity, which may cause the material to absorb impurities such as dust and fiber, affecting the quality and performance of the catheter. Water mist can increase the ambient humidity and reduce the generation and accumulation of static electricity.

[0034] Multiple fans 24 and water pipes 23 are arranged in an interlaced manner, so that multiple atomizing nozzles 28 can dissipate heat more evenly with multiple fans 24, and the outer sides of multiple water pipes 23 are fixedly connected with solenoid valves 8, which control the water pressure to convert the water in the water pipes 23 into atomized water for spraying.

[0035] A water pump 25 is fixedly connected to one side above the transmission component 3, and the input end of the water pump 25 is connected to a cold water tank 27. The cold water tank 27 is placed below the transmission component 3, and the output end of the water pump 25 is connected to the lower cavity 29. A heat-conducting component 6 is fixedly connected between the transmission component 3 and the cold water tank 27. The heat-conducting component 6 includes a heat-conducting plate 61 and a heat sink 62. The heat-conducting plate 61 is fixedly connected to the inner bottom of the transmission component 3, and the heat sink 62 is fixedly connected to the bottom of the heat-conducting plate 61. The heat sink 62 extends out of the transmission component 3 and extends into the interior of the cold water tank 27. Multiple heat sinks 62 are arranged at intervals. Generally speaking, in large industrial knitting machines, in order to protect the transmission components from external interference, reduce safety hazards and maintain the stability and accuracy of the equipment, the transmission components are usually arranged inside. In this way, the casing and protective devices can be used to prevent dust and debris from entering the transmission system, and at the same time prevent operators from accidentally contacting moving parts and causing injuries. The transmission component 3 usually requires rapid reciprocating and frequent movements, which will lead to rapid conversion and accumulation of energy. For example, pulleys, gears, etc., will generate more heat due to frequent friction when running at high speed, and long-term high temperature will easily cause metal parts to expand and deform, and belts will easily age and break, which will easily affect the fit between the transmission component 3 and the weaving mechanism 1 and the weaving accuracy. The heat conducting plate 61 is located at the inner bottom of the transmission component 3, which is more likely to absorb the heat generated by the transmission component 3 when it is working, and conduct the heat to the external air and the cold water tank 27 through multiple heat sinks 62, for effective heat conduction and uniform heat dissipation, so as to maintain the stability of the weaving of the transmission component 3 in cooperation with the weaving mechanism 1.

[0036] The top of the cold water tank 27 is connected with an air vent 9 and a water inlet pipe 7. The heat inside the cold water tank 27 can be discharged outwardly through the air vent 9. The water inlet pipe 7 can replenish water to the cold water tank 27. The air vent 9 and the water inlet pipe 7 are both bent. The bent air vent 9 can prevent the hot air from the cold water tank 27 from dissipating toward the transmission component 3. The bent water inlet pipe 7 is convenient for connection with an external water supply system to keep the temperature and water level of the cold water tank 27 within a certain range. For example, when the water temperature exceeds a certain range, the external water supply system can add water or change water to the cold water tank 27, but generally speaking, when the weaving mechanism 1 and the transmission mechanism 3 are working, the heat dissipation mechanism 2 also works together, so that the water in the cold water tank 27 is in a state of continuous output, and the water inlet pipe 7 can also continuously take in a small amount of water, or when the water level is lower than a certain level, water is added centrally, so that the water level and temperature of the cold water tank 27 can be ensured to be within a certain range, thereby ensuring the stability of the heat conduction and heat dissipation of the transmission component 3 by the heat conductive component 6.

[0037] A controller 4 is fixedly connected to one side of the transmission component 3, and the controller 4 is electrically connected to the transmission component 3, the heat dissipation mechanism 2 and the weaving mechanism 1. A support frame 5 is fixedly connected to the bottom of the transmission component 3. The protective cover 22 is arranged in a circular ring shape, which matches the shape of the multiple components of the weaving mechanism 1. The ventilation mesh port 21 is opened in a ring shape on the inner upper part of the protective cover 22.

[0038] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
