Technical Field
[0001] This utility model belongs to the field of temperature control devices, specifically relating to a temperature control device for an extrusion device. Background Technology
[0002] Cables are primarily used to transmit electrical energy, information, and convert electromagnetic energy. They are typically long and transmit complex types of data. To protect these cables, CPVC (carbon PVC) is generally used to produce cable protection pipes. CPVC possesses characteristics such as high strength, toughness, high temperature resistance, corrosion resistance, good insulation, no pollution, and resistance to aging. CPVC is processed into cable protection pipes through extrusion molding. Currently, the temperature of the screw conveyor chamber is manually controlled during use, but this method is not precise enough. Summary of the Invention

[0007] Furthermore, the refrigeration mechanism includes a first water tank and a first circulation pump.

[0018] Preferred embodiment.
[0019] This embodiment provides a temperature control device for an extrusion apparatus, including an extruder 100 and a temperature control mechanism. The temperature control mechanism is disposed on the extruder 100 and includes a heating mechanism and a cooling mechanism. The heating mechanism includes a first electric heating wire 250 and a first temperature control switch 140. A first heating chamber 110 is provided on the outer side of the extruder 100. The first electric heating wire 250 is wound inside the first heating chamber 110. The first temperature control switch 140 is electrically connected to the first electric heating wire 250. The cooling mechanism includes a first copper tube 200, which is wound inside the first heating chamber 110 and is attached to the first electric heating wire 250.
[0020] Furthermore, a first heat exchange plate 210 is provided on one side of the first copper tube 200, and a first slot 220 is provided in the middle of the first heat exchange plate 210, which is matched with the first electric heating wire 250.
[0021] Furthermore, the refrigeration mechanism includes a first water tank 130 and a first circulation pump 120. One end of the first copper pipe 200 is connected to the first circulation pump 120, and the other end of the first copper pipe 200 is connected to the first water tank 130, thus connecting the first circulation pump 120 to the first water tank 130.
[0022] Furthermore, the cooling mechanism includes a plurality of first temperature sensors 150, which are disposed within the first heating chamber 110.
[0023] Furthermore, the first card slot 220 has first limiting protrusions 230 at both ends of the slot opening, and the first limiting protrusions 230 are arranged opposite each other to form a first constriction 240.
[0024] Working principle: The first copper tube 200 is wound inside the first heating chamber 110, and the first electric heating wire 250 is attached to the first copper tube 200 and placed in the first slot 220. The first constriction 240 limits the first electric heating wire 250, preventing it from falling out of the slot 220, thus ensuring stable installation. When heating and melting the raw material in the extruder 100, the first electric heating wire 250 is energized to heat the extruder 100 to the required temperature. If the temperature is too high, the first temperature control switch 140 can de-energize the first electric heating wire 250, stopping heating. Furthermore, the first temperature sensor 150 can detect the temperature inside the first heating chamber 110, and based on the feedback from the first temperature sensor 150, it can drive the first circulation pump 120 to transport the water in the first water tank 130 into the first copper pipe 200, which can quickly absorb the heat from the first electric heating wire 250 and the first heating chamber 110, and quickly cool down.
[0025] It is worth mentioning that the technical features of the extruder 100 and other related technologies involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the utility model point of this utility model patent. This utility model patent will not elaborate further.
[0026] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
