Description

Technical Field

[0001] This utility model relates to the technical field of temperature control mechanisms for cable extruders, specifically a temperature control mechanism for cable extruders. Background Technology

[0002] Cable extruders are widely used in the blending and modification of polymer materials such as general-purpose plastics, cross-linked polyethylene, engineering plastics, and thermoplastic rubber, as well as in the processing of special fibers and special adhesives. In existing cable production technology, the high-speed operation of the extruder generates a large amount of frictional and shear heat, which disrupts the thermal balance, causing the temperature to rise excessively high, exceeding the process temperature. This significantly impacts product quality and can even halt production. Therefore, effective temperature control is essential.

[0003] A search revealed that Chinese utility model patent CN207207098U discloses a cable extruder with easy temperature control. The extruder includes a cable extrusion body, a motor mounted on the body, a gearbox on one side of the motor, a feeding hopper on one side of the gearbox, a stirring paddle inside the feeding hopper, a stirring motor mounted on the feeding hopper, a screen at the bottom of the feeding hopper, a heating device at the bottom of the feeding hopper, a control box on one side of the heating device with a temperature control button, a material cylinder on one side of the control box with a temperature sensing element, a cooling box on the material cylinder, a water-cooled control box at the bottom of the cooling box, a base at the bottom of the water-cooled control box, and an extruder head at one end of the material cylinder. This cable extruder incorporates a water-cooled temperature control device, completely encasing the material cylinder within the cooling box for enhanced heat dissipation. Simultaneously, the temperature sensing element allows for real-time temperature measurement, facilitating temperature regulation.

[0004] The existing device has the following shortcomings when in use: The temperature control mechanism of the existing cable extruder controls the temperature by injecting hot water. When the hot water is at one end of the heat exchanger for a period of time, the hot water will be on top and the cold water will be on the bottom because the density of hot water is lower than that of cold water. This makes the temperature in the settling tank uneven and cannot control the temperature well, thus affecting the performance of the cable extrusion. Utility Model Content

[0005] The purpose of this invention is to provide a temperature control mechanism for a cable extruder to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature control mechanism for a cable extruder, comprising a settling tank, a settling spiral pipe, a cold water pipe, a hot water pipe, a hot water circulation tank, a PLC controller, a temperature sensor, and a water flow surfing device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a technical solution: a temperature control mechanism for a cable extruder, comprising a settling tank 1, a settling spiral pipe 3, a cold water pipe 4, a hot water pipe 7, a hot water circulation tank 9, a PLC controller 10, a temperature sensor 11, and a water flow surging device 12. An input pipe 2 is installed on the settling tank 1, and a pump D16 is installed on the input pipe 2. The input pipe 2 is connected to the settling spiral pipe 3 installed inside the settling tank 1. Activating the pump D16 on the input pipe 2 draws the cable solution into the settling spiral pipe 3 installed inside the settling tank 1. Inside the spiral pipe 3, the heated hot water from the hot water circulation tank 9 is then transported to the settling tank 1 through the hot water pipe 7. This allows the hot water in the settling tank 1 to exchange heat with the settling spiral pipe 3, facilitating heat exchange in the cable. The settling tank 1 is equipped with a cold water pipe 4 and a hot water pipe 7, the other end of which is connected to the hot water circulation tank 9. A temperature sensor 11 is installed inside the settling tank 1, and a PLC controller 10 is also installed. A water flow surfing device 12 is installed at the bottom of the settling tank 1. During the heat exchange process… By activating the water flow surfing device 12 installed at the bottom of the settling tank 1, the hot water inside the settling tank 1 can be surfed, ensuring that the hot water in the settling tank 1 is constantly flowing vertically, preventing the stratification of hot and cold water, and ensuring uniform temperature within the settling tank 1. This improves the heat exchange efficiency of the cable solution and also ensures that the temperature detected by the temperature sensor 11 installed inside the settling tank 1 is accurate, facilitating temperature control. A circulation pipe 6 is installed on the settling tank 1, and the other end of the circulation pipe 6 is connected to the hot water circulation tank 9. A pump B14 is installed on the settling tank 1. When the temperature sensor 11 detects a low temperature, it sends a command to the PLC controller 10. The PLC controller 10 controls pumps B14 and C15 to pump out the warm water in the settling tank 1 and then input hot water. A pump A13 is installed on the cold water pipe 4. An electric heating wire layer 8 is installed in the wall of the hot water circulation tank 9. An output pipe 5 is installed on the settling tank 1, and a pump C15 is installed on the hot water pipe 7. The PLC controller 10 is connected to the temperature sensor 11 and the pumps on the cold and hot pipes. The circuit modules and electronic components involved in this application are all existing mature technologies, and there are many products on the market. Furthermore, the protection content of this application does not involve improvements to the software and methods, so they will not be explained in detail here.

[0021] Working principle: The pump D16 installed on the input pipe 2 is activated to draw the cable solution into the settling spiral pipe 3 installed in the settling tank 1. Then, the heated hot water in the hot water circulation tank 9 is transported to the settling tank 1 through the hot water pipe 7. In this way, the hot water in the settling tank 1 and the settling spiral pipe 3 exchange heat, allowing the cable solution to exchange heat. During the heat exchange process, the water flow surfing device 12 installed at the bottom of the settling tank 1 is activated to surf the hot water in the settling tank 1. In this way, the hot water in the settling tank 1 is always in an up-and-down flow state, avoiding the phenomenon of hot and cold water stratification and ensuring the uniformity of temperature in the settling tank 1. This improves the heat exchange effect of the cable solution and also makes the temperature detected by the temperature sensor 11 installed in the settling tank 1 accurate, which is convenient for temperature control. When the temperature sensor 11 detects a low temperature, it will send a command to the PLC controller 10. The PLC controller 10 controls the pumps B14 and C15 to pump out the warm water in the settling tank 1 and then input hot water.
