Description
Technical Field
[0001] This application relates to the technical field of sewing devices, and specifically to an automobile seat fabric stitching device. Background Art
[0002] The statements in this part only provide background technical information related to this application and do not necessarily constitute prior art.
[0003] In the stitching of automobile seat fabrics, an electric sewing machine is generally used. However, in large-scale production, during the long-term use of the electric sewing machine, the current and voltage inside the motor will increase, resulting in an increase in the motor temperature, thus generating a heating phenomenon, which affects the service life of the electric sewing machine.
[0004] Patent Publication No.: CN219137121U discloses an automobile seat fabric sewing machine. There is a water tank on the right side of the sewing machine, and an air duct is connected on the right side. There are heat dissipation blocks, copper tubes, etc. inside the air duct. There is a submersible pump in the water tank. Through the collaborative work of components such as a semiconductor refrigeration sheet, a heat conduction component, and a heat dissipation fan, the water in the water tank is cooled, the air in the air duct is cooled, and the low-temperature air is transmitted to the inside of the sewing machine through the wind force of the diversion fan to assist in heat dissipation, improving the processing efficiency. However, there is lubricating oil between the internal mechanical connecting shafts of the sewing machine for lubrication. The cold air conveyed by the diversion fan will dry the lubricating oil, resulting in the loss of lubricating oil, affecting the smooth rotation between the shafts, and further affecting the normal working state and service life of the sewing machine. Therefore, a stitching device that can cool the motor heat generation and does not affect the service life is needed. Summary of the Utility Model

[0021] Embodiment 1
[0022] An automobile seat fabric stitching device, as Figures 1-3 shown, includes: a sewing machine body 1, a liquid storage tank 2, a liquid extraction pump 11, a heat exchanger 3, and a liquid delivery pipe 4. A first cooling pipe 8 is provided on the inner wall of the sewing machine body 1 to cool the sewing machine body 1. A second cooling pipe 9 is provided on the surface of the motor 10 of the sewing machine body 1 to directly cool the motor 10. The liquid inlets of the first cooling pipe 8 and the second cooling pipe 9 are connected to the liquid delivery pipe 4. One end of the liquid delivery pipe 4 away from the first cooling pipe 8 is connected to the liquid extraction pump 11. The liquid extraction pump 11 is located in the liquid storage tank 2. The liquid storage tank 2 is filled with a coolant. The liquid outlets of the first cooling pipe 8 and the second cooling pipe 9 are connected to the liquid inlet of the heat exchanger 3 through a pipeline. The heat exchanger 3 cools the coolant with an increased temperature, and the liquid outlet of the heat exchanger 3 is connected to the liquid storage tank 2 through a pipeline, so that the coolant can be recycled.
[0023] As Figure 3 shown, the first cooling pipe 8 is spirally adhered to the inner surface of the sewing machine body 1 to create a low-temperature working environment for the sewing machine body 1 and prevent the working temperature of the sewing machine body 1 from being too high.
[0024] As Figure 3 shown, the second cooling pipe 9 is spirally wound around the surface of the motor 10. Through the heat transfer of the second cooling pipe 9, the motor 10 can be directly cooled. The cooling directly acts on the surface of the motor 10, and the cooling efficiency is higher.
[0025] As Figure 2 shown, the first cooling pipe 8 and the second cooling pipe 9 are copper pipes with a circular cross-section, which are convenient for shaping and have better heat transfer efficiency.
[0026] As Figure 1 shown, a vent 7 is further provided on the top of the sewing machine body 1 to dissipate heat and observe the working state of the motor 10 inside the sewing machine body 1 through the vent 7.
[0027] As Figure 1As shown in the figure, it further includes a temperature sensor 5 and a controller 6. The temperature probe end of the temperature sensor 5 is inserted into the sewing machine body 1. The signal transmission end of the temperature sensor 5 is connected to the controller 6. The controller 6 is connected to the shell of the sewing machine body 1. The temperature sensor 5 transmits the temperature inside the sewing machine body 1 to the controller 6. When the temperature reaches the set temperature, for example, the set temperature is 50 degrees, the controller 6 then sends an opening signal to the liquid extraction pump 11, and the liquid extraction pump 11 starts to work. The coolant cools the sewing machine body 1 through the first cooling pipe 8 and the second cooling pipe 9.
[0028] The heat exchanger 3 is a micro heat exchanger 3.
[0029] The model of the controller 6 is s7-200, and the model of the temperature sensor 5 is GX1831.
[0030] In the technical solution of this application, after the sewing machine body 1 works for a long time and the motor 10 rotates for a long time, the temperature rises. At this time, the liquid extraction pump 11 is turned on. The liquid extraction pump 11 pumps the coolant out of the liquid storage tank 2 and transports it to the first cooling pipe 8 and the second cooling pipe 9 through the infusion pipe 4. The first cooling pipe 8 adheres to the inner wall of the sewing machine body 1 to cool the whole sewing machine body 1. The second cooling pipe 9 is spirally wound around the surface of the motor 10 to directly cool the motor 10. The motor 10 is the heat source, and the second cooling pipe 9 can directly cool the heat source, and then the first cooling pipe 8 cools the whole sewing machine body 1. Through the two-level cooling method, the inside of the sewing machine body 1 is quickly cooled to prevent the temperature of the motor 10 from being too high and affecting the service life of the sewing machine body 1. The coolant in the first cooling pipe 8 and the second cooling pipe 9 is sent into the heat exchanger 3 through the return pipeline for cooling, and the cooled coolant then flows back into the liquid storage tank 2 for storage, thus realizing the recycling of the coolant.
[0031] Although the specific implementation manners of this application are described above in conjunction with the drawings, it is not a limitation to the protection scope of this application. Those skilled in the art should understand that based on the technical solution of this application, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of this application.
