Description

Technical Field

[0001] This utility model relates to the field of needle cooling technology, and in particular to a needle cooling device for computerized sewing machines. Background Technology

[0002] Computerized sewing machines operate at high speeds. During use, the needles generate heat due to high-speed friction. The high temperature can cause the thread to bleed color. This can affect the quality when sewing shoes with different shades of color. For example, if red thread is sewn on white fabric, the white fabric will be affected by the red thread, and the finished product will not meet the customer's requirements for appearance.

[0003] For example, Chinese Patent Publication No. CN222313501U discloses a needle cooling device for computerized sewing machines, including a computerized sewing machine head, a water tank at the sewing machine head, and a coil inside the water tank; an air inlet pipe is connected to the top of the coil and connected to an external air pump; a connector is provided at the bottom of the coil through the bottom of the water tank for connecting an air blowing pipe; the air outlet of the air blowing pipe is aligned with the needle of the computerized sewing machine head.

[0004] However, in the above scheme, although the device cools the airflow in the pipe with cold water during use, it cannot stir the water in the water tank. As a result, the water near the pipe becomes hotter after heat exchange with the pipe, while the water far away from the pipe remains cold, thus affecting the cooling effect on the airflow in the pipe and reducing the utilization efficiency of the cold water. Utility Model Content

[0005] This invention provides a needle cooling device for computerized sewing machines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A needle cooling device for a computerized sewing machine includes a computerized sewing machine head, a needle body at the bottom of the computerized sewing machine head, a water tank fixedly connected to the side wall of the computerized sewing machine head, a spiral tube fixedly connected inside the water tank, the top of the spiral tube extending out of the top of the water tank, the bottom of the spiral tube extending out of the bottom of the water tank, and an L-shaped air blowing pipe fixedly connected to the bottom of the spiral tube, with one end of the L-shaped air blowing pipe facing the needle body.

[0008] Both sides of the spiral tube are fixedly connected to fixed pipes, and both fixed pipes are connected to the inside of the spiral tube. Rotating rods are rotatably connected to the inside of each fixed pipe via sealed bearings. The two ends of each rotating rod are rotatably connected to the two side walls inside the water tank. Multiple stirring rods are fixedly connected to the outer side walls of each rotating rod. A connecting rod is fixedly connected between the two rotating rods and rotatably connected inside the spiral tube. Multiple blades are fixedly connected to the outer side wall of the connecting rod, and these blades are rotatably connected inside the spiral tube. An inclined guide plate is fixedly connected inside the spiral tube, and the inclined guide plate is located above the connecting rod.

[0009] As a further improvement to this technical solution: a water inlet is fixedly connected to the top of the water tank, the top of the water inlet is provided with a cap, a water outlet is fixedly connected to the bottom of the water tank, and a sealing cap is threadedly connected to the bottom of the water outlet.

[0010] As a further improvement to this technical solution: the water tank is made of heat-insulating material.

[0011] As a further improvement to this technical solution: three reinforcing rods are fixedly connected to the bottom of the water tank, and a reinforcing ring is fixedly connected to one end of each of the three reinforcing rods. The reinforcing ring is slidably connected to the outer side wall of the L-shaped air blowing pipe.

[0012] As a further improvement to this technical solution: a connector is fixedly connected to the bottom of the spiral tube, and the top of the L-shaped air blowing tube is threadedly connected to the connector.

[0013] As a further improvement to this technical solution: the water tank is equipped with a semiconductor cooling chip and a temperature sensor.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this device, cold water can be poured into the water tank through the water inlet. One end of the spiral tube is connected to an external air pump, and the gas enters the L-shaped air blowing tube through the spiral tube. The gas blown out through the L-shaped air blowing tube cools the needle body. The cold water in the water tank can cool the gas in the spiral tube, making the gas blown out by the L-shaped air blowing tube cool air, thereby preventing the needle body from overheating and causing the thread to overflow. The inclined guide plate can block the airflow in the spiral tube, causing the airflow to move along the inclined side wall of the inclined guide plate, so that the airflow flows downward between the inclined guide plate and the inner wall of the spiral tube. At this time, the airflow blows within. At the top of a blade, the blade rotates under the influence of airflow. The blade drives two rotating rods via a connecting rod, which in turn drive multiple stirring rods. The rotation of these stirring rods agitates the water in the tank, making the water temperature more uniform and preventing uneven distribution of temperature, such as higher temperatures near the spiral tube and lower temperatures further away. This improves the cooling effect of the airflow within the spiral tube and enhances the cooling of the needle body. A temperature sensor detects the water temperature in the tank, and when the temperature rises, a semiconductor cooling chip is activated to cool the water. The rotation of the multiple stirring rods further contributes to the rapid and uniform cooling of the water in the tank.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described in more detail below by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0024] For examples, please refer to Figure 1-4 This utility model provides a technical solution: a needle cooling device for computerized sewing machines, including a computerized sewing machine head 1, a needle body 2 at the bottom of the computerized sewing machine head 1, a water tank 6 fixedly connected to the side wall of the computerized sewing machine head 1, a spiral tube 7 fixedly connected inside the water tank 6, the top of the spiral tube 7 extending out of the top of the water tank 6, the bottom of the spiral tube 7 extending out of the bottom of the water tank 6, and an L-shaped air blowing tube 3 fixedly connected to the bottom of the spiral tube 7, with one end of the L-shaped air blowing tube 3 facing the needle body 2.

[0025] Both sides of the spiral tube 7 are fixedly connected to fixed pipes 15, and both fixed pipes 15 are connected to the inside of the spiral tube 7. Both fixed pipes 15 are rotatably connected to rotating rods 10 through sealed bearings 16. The two ends of the two rotating rods 10 are respectively rotatably connected to the two inner side walls of the water tank 6. Multiple stirring rods 19 are fixedly connected to the outer side walls of the two rotating rods 10. A connecting rod 17 is fixedly connected between the two rotating rods 10. The connecting rod 17 is rotatably connected to the inside of the spiral tube 7. Multiple blades 18 are fixedly connected to the outer side walls of the connecting rod 17. The multiple blades 18 are rotatably connected to the inside of the spiral tube 7. An inclined guide plate 14 is fixedly connected inside the spiral tube 7. The inclined guide plate 14 is located above the connecting rod 17.

[0026] Please see Figure 1-3 The water tank 6 is fixedly connected to the top of the water inlet 8, and the top of the water inlet 8 is equipped with a cap. The water tank 6 is fixedly connected to the bottom of the water outlet 12, and the bottom of the water outlet 12 is threaded with a sealing cap, which facilitates the addition or drainage of water into the water tank 6.

[0027] Please see Figure 1-3Water tank 6 is made of heat-insulating material, which can keep the water in water tank 6 warm and prevent the temperature of the water in water tank 6 from being affected by the outside temperature.

[0028] Please see Figure 2-3 The water tank 6 is equipped with a semiconductor cooling chip 9 and a temperature sensor 13. The temperature sensor 13 can detect the temperature of the water source in the water tank 6, and the semiconductor cooling chip 9 can cool and reduce the temperature of the water source.

[0029] Specifically, when using this device, cold water can be filled into the water tank 6 through the water inlet 8. One end of the spiral tube 7 is connected to an external air pump, and the gas enters the L-shaped air blowing pipe 3 through the spiral tube 7. The gas blown out through the L-shaped air blowing pipe 3 cools the needle body 2. The cold water in the water tank 6 can cool the gas in the spiral tube 7, making the gas blown by the L-shaped air blowing pipe 3 cool, thereby preventing the needle body 2 from overheating and causing the thread to overflow. The inclined guide plate 14 can block the airflow in the spiral tube 7, causing the airflow to move along the inclined side wall of the inclined guide plate 14, so that the airflow flows downward between the inclined guide plate 14 and the inner wall of the spiral tube 7. At this time, the airflow blows on the top of one of the blades 18. Rotated by the airflow, the blade 18 drives two rotating rods 10 to rotate via the connecting rod 17. The two rotating rods 10 drive multiple stirring rods 19 to rotate. When the multiple stirring rods 19 rotate, they can stir the water in the water tank 6, making the temperature of the water in the water tank 6 more uniform. This prevents the water near the spiral tube 7 from being hotter and the water far from the spiral tube 7 from being colder, thereby improving the cooling effect of the airflow in the spiral tube 7 and improving the cooling effect of the needle body 2. The temperature of the water in the water tank 6 can be detected by the temperature sensor 13. When the temperature rises, the semiconductor cooling chip 9 can be activated to cool the water. The rotation of the multiple stirring rods 19 can help the water in the water tank 6 to be cooled quickly and evenly.

[0030] Please see Figure 1-2 Three reinforcing rods 5 are fixedly connected to the bottom of the water tank 6. One end of each of the three reinforcing rods 5 is fixedly connected to a reinforcing ring 4. The reinforcing ring 4 is slidably connected to the outer side wall of the L-shaped air pipe 3. The reinforcing ring 4 can limit the L-shaped air pipe 3, thereby improving the stability of the L-shaped air pipe 3 during use and preventing the L-shaped air pipe 3 from bending after long-term use.

[0031] Please see Figure 1-3 The bottom of the spiral tube 7 is fixedly connected to the connector 11, and the top of the L-shaped air tube 3 is threadedly connected to the connector 11, which facilitates quick disassembly and replacement of the L-shaped air tube 3.

[0032] The working principle of this utility model is as follows: When using this device, cold water can be poured into the water tank 6 through the water inlet 8. One end of the spiral tube 7 is connected to an external air pump. Gas enters the L-shaped air blowing pipe 3 through the spiral tube 7 and is blown out through the L-shaped air blowing pipe 3 to cool the needle body 2. The cold water in the water tank 6 can cool the gas in the spiral tube 7, making the gas blown by the L-shaped air blowing pipe 3 cool, thereby preventing the needle body 2 from overheating and causing the thread to overflow. The inclined guide plate 14 can block the airflow in the spiral tube 7, causing the airflow to move along the inclined side wall of the inclined guide plate 14, so that the airflow flows downward between the inclined guide plate 14 and the inner wall of the spiral tube 7. At this time, the airflow blows on the top of one of the blades 18. The blade 18 rotates under the blowing of the airflow. The blade 18 drives the two rotating rods 10 to rotate through the connecting rod 17. The two rotating rods 10 drive the multiple stirring rods 19 to rotate. When the multiple stirring rods 19 rotate, they can stir the water source in the water tank 6, so that the temperature of the water source in the water tank 6 is more uniform. This prevents the water source near the spiral tube 7 from being hot and the water source far away from the spiral tube 7 from being cold, thereby improving the cooling effect of the airflow in the spiral tube 7 and improving the cooling effect of the needle body 2. The temperature of the water source in the water tank 6 can be detected by the temperature sensor 13. When the temperature rises, the semiconductor cooling chip 9 can be activated to cool the water source. The rotation of the multiple stirring rods 19 can help the water source in the water tank 6 to be cooled quickly and evenly.
