At the same time, it is also impossible to clean the inner wall of the equipment. After use, liquid will remain on the inner wall of the equipment, causing the previous liquid to be used the next time, thereby reducing the temperature control and scraping effect of the traditional blending kettle. For this reason, an automatic temperature control device for the blending kettle has been introduced. Utility Model Content

During the movement of the pressure block, the connecting rod and the limit block are driven to move, so that the heat inside the heating tube flows out from the notch of the heating tube, thereby realizing cooling of the heating tube and the blending kettle body. When the temperature sensor detects that the temperature inside the blending kettle body is low, it sends a signal to the solenoid valve and the heating device, so that the valve of the solenoid valve is closed while the heating device continues heating, so that the stability of the interior of the blending kettle body is always maintained in a constant temperature state for operation.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1 - Figure 5 A blending kettle automatic temperature control device includes a blending kettle body 1, a motor 5 is fixedly installed on the top of the blending kettle body 1, a heating device 2 is provided on the outer wall of the blending kettle body 1, a controller 3 is fixedly installed on the outer wall of the heating device 2, a heat pipe 4 is fixedly installed on the side of the heating device 2 close to the blending kettle body 1, a placement groove 7 is opened on the inner wall of the blending kettle body 1, a heating pipe 6 is provided on the inner wall of the placement groove 7, an electromagnetic valve 11 is fixedly installed on the end of the heating pipe 6 close to the motor 5, and a temperature sensor 8 is fixedly installed on the inner wall of the blending kettle body 1.

[0023] In the above structure, heat is transferred to the inner wall of the heating tube 6 through the heating device 2 via the heat pipe 4, so that the heating tube 6 heats the inner wall of the blending kettle body 1, and the inner wall of the heating tube 6 is sealed by the solenoid valve 11, so that the heat of the heating tube 6 will not flow out when the solenoid valve 11 is closed.

[0024] In a preferred embodiment: the power output shaft of the motor 5 is fixedly assembled with a rotating shaft 9, the outer wall of the rotating shaft 9 is provided with a scraping assembly 10, the inner wall of the end of the heating tube 6 close to the solenoid valve 11 is fixedly assembled with a fixed block 12, the outer wall of the fixed block 12 is fixedly assembled with one end of a spring 13, the other end of the spring 13 is fixedly assembled with a pressure block 14, the end of the pressure block 14 close to the spring 13 is fixedly assembled with one end of a connecting rod 15, and the other end of the connecting rod 15 is fixedly assembled with a limiting block 16.

[0025] In the above structure, the temperature inside the blending kettle body 1 is continuously monitored by the temperature sensor 8. When the temperature inside the blending kettle body 1 exceeds the preset threshold, the temperature sensor 8 sends a command signal to the solenoid valve 11 and the heating device 2, and the solenoid valve 11 will start the valve opening program, and the heating device 2 will stop the heating process. Subsequently, the pressure inside the heating tube 6 will act on the pressure block 14, pushing the pressure block 14 to move on the inner wall of the heating tube 6. During the movement of the pressure block 14, it will link the connecting rod 15 and the limit block 16 to move accordingly, prompting the heat inside the heating tube 6 to be smoothly discharged from the notch of the heating tube 6, thereby achieving effective cooling of the heating tube 6 and the blending kettle body 1. Conversely, when the temperature sensor 8 detects that the temperature inside the blending kettle body 1 drops to a low threshold, the system will again send a command signal to the solenoid valve 11 and the heating device 2 through the temperature sensor 8. At this time, the solenoid valve 11 will execute the valve closing operation, and the heating device 2 will resume the heating function, ensuring that the temperature inside the blending kettle body 1 is always maintained at a constant state to ensure its normal operation.

[0026] In a preferred embodiment: the scraping assembly 10 includes a rotating rod 1001, the outer wall of the rotating rod 1001 is provided with a limiting groove 1002, the inner wall of the limiting groove 1002 is fixedly equipped with a fixed rod 1003, the outer wall of the fixed rod 1003 is slidably connected to a moving block 1004, the inner wall of the moving block 1004 is rotatably connected to a rotating column 1005, the outer wall of the rotating column 1005 is fixedly equipped with one end of a pressure rod 1006, the other end of the pressure rod 1006 is fixedly equipped with a scraper 1008, and the outer wall of the moving block 1004 is fixedly equipped with a spring 2 1007.

[0027] In the above structure, when the blending kettle body 1 finishes working, the controller 3 sends a signal to make the power output shaft of the motor 5 rotate after receiving the signal, and the motor 5 drives the rotating shaft 9 to rotate, so that the rotating shaft 9 drives the scraping assembly 10 to rotate accordingly during the rotation process, and the scraper 1008 is responsible for scraping the residual liquid on the inner wall of the blending kettle body 1 to ensure the cleanliness of the system. At the same time, the scraper 1008 will apply a certain pressure to the pressure rod 1006 during the operation, so that the pressure rod 1006 drives the rotating column 1005 to move in the moving block after being subjected to the pressure. The inner wall of 1004 rotates. When the rotating column 1005 rotates, it applies a certain pressure to the moving block 1004, causing the moving block 1004 to move on the outer wall of the fixed rod 1003 after being subjected to the pressure. As the moving block 1004 moves, it applies pressure to the spring 2 1007, so that the elastic potential energy accumulated in the spring 2 1007 is released, and then pushes the spring 2 1007 to drive the scraper 1008 to retract and retract, ensuring that the scraper 1008 will not break during operation, thereby ensuring that the entire equipment can operate stably.

[0028] In a preferred embodiment, the heat conducting tube 4 is connected to the inner wall of the heating tube 6 , the second spring 1007 is fixedly assembled with the inner wall of the limiting groove 1002 , and the rotating rod 1001 is fixedly assembled with the outer wall of the rotating shaft 9 .

[0029] In the above structure, the heat generated by the heating device 2 is transported to the inner wall of the heating tube 6 for storage through the heat pipe 4, and the spring 2 1007 is fixed with the limiting groove 1002 and the moving block 1004 to limit the spring 2 1007, and the scraping component 10 is limited by the rotating shaft 9.

[0030] In a preferred embodiment, the motor 5 , the temperature sensor 8 , the solenoid valve 11 and the heating device 2 are all electrically connected to the controller 3 , and the temperature sensor 8 is electrically connected to the solenoid valve 11 and the heating device 2 .

[0031] In the above structure, the controller 3 sends a signal, so that the device works after receiving the signal, and the temperature sensor 8 directly sends a warning to the solenoid valve 11 and the heating device 2.

[0032] In a preferred embodiment, there are two groups of scraping assemblies 10 , and the two groups of scraping assemblies 10 are respectively located on the outer wall of the rotating shaft 9 .

[0033] In the above structure, the two groups of scraping assemblies 10 enable the scraping assemblies 10 to scrape the liquid remaining on the inner wall of the blending kettle body 1 more quickly and neatly.

[0034] Working principle: After strict monitoring of the internal temperature of the system, when the internal temperature of the blending kettle body 1 rises abnormally, the system will send a command signal to the solenoid valve 11 and the heating device 2 through the temperature sensor 8, prompting the solenoid valve 11 to start the valve opening operation, and the heating device 2 will stop heating, so that the pressure inside the heating tube 6 acts on the pressure block 14, pushing the pressure block 14 to move on the inner wall of the heating tube 6. As the pressure block 14 moves, it will drive the connecting rod 15 and the limit block 16 to move accordingly, so that the heat inside the heating tube 6 can flow out smoothly from the preset notch, thereby achieving the cooling effect on the heating tube 6 and the blending kettle body 1. When the temperature sensor 8 detects that the internal temperature of the blending kettle body 1 drops to a safe range, the system will again send a command signal to the solenoid valve 11 and the heating device 2, prompting the solenoid valve 11 to close the valve, and the heating device 2 resumes the heating operation to ensure that the internal temperature of the blending kettle body 1 continues to maintain at a preset constant temperature state. After the equipment completes its working cycle, the controller 3 will send an end signal. After receiving the signal, the motor 5 will trigger the rotation of its power output shaft. Through the rotation of the motor 5, the rotating shaft 9 is further driven to rotate. The rotational movement of the rotating shaft 9 will drive the scraping assembly 10 to rotate synchronously. At this time, the scraper 1008 scrapes the residual liquid on the inner wall of the blending kettle body 1, and applies pressure to the pressure rod 1006 during the working process. The pressure rod 1006 under pressure will drive the rotating column 1005 to rotate on the inner wall of the moving block 1004. The rotating column 1005 will apply pressure to the moving block 1004 during the rotation process, so that the moving block 1004 moves on the outer wall of the fixed rod 1003. As the moving block 1004 moves, pressure is applied to the spring 2 1007 to release the elastic potential energy stored in the spring 2 1007, thereby driving the scraper 1008 to perform telescopic movement, ensuring that the scraper 1008 will not break due to excessive force during the working process.
