Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a disposable extrusion connecting tube. Background Technology

[0002] In modern industrial production, many fields, such as plastics processing, food packaging, and chemical raw material extrusion molding, have strict requirements for material extrusion and conveying. Disposable extrusion connectors, as key components connecting the extruder and die to achieve efficient and precise material transfer, directly impact product quality and production efficiency. As production processes continue to evolve towards refinement and efficiency, even more stringent challenges are being placed on the functional characteristics of disposable extrusion connectors.

[0003] Currently, most extrusion connectors on the market employ a simple rigid pipe structure to connect the extruder and die. External heating equipment heats the entire pipe to meet the material plasticization requirements. Temperature monitoring relies on an independent temperature sensor installed outside the pipe, transmitting the temperature signal to a controller to adjust the heating equipment power. Traditional flange or threaded connections are commonly used to ensure a secure connection between the pipe and the equipment.

[0004] Existing extrusion connecting pipes, due to their rigid pipe structure, lack flexibility when facing complex production space layouts, leading to inconvenient installation. At the same time, when subjected to high extrusion pressure, pipe deformation and rupture are prone to occur, affecting the continuity and stability of production. Therefore, a disposable extrusion connecting pipe is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a disposable extruded connecting pipe, which aims to improve the problem that the existing extruded connecting pipes are not pressure resistant enough and are prone to deformation and rupture when subjected to high extrusion pressure, thus affecting the continuity and stability of production.

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

[0007] A disposable extruded connecting tube includes a copper tube with a heating wire wound around its sidewall, a thermocouple provided on the sidewall of the copper tube, nuts on both sides of the copper tube, and the copper tube is flared to ensure that the nuts do not fall off, and insulation cotton is fitted on the sidewall of the copper tube.

[0008] As a further description of the above technical solution:

[0009] The inner wall of the insulation cotton is attached to the heating wire. The insulation cotton is used to maintain the temperature at the connection point and to prevent the risk of burns during operation.

[0010] As a further description of the above technical solution:

[0011] The outer side of the insulation cotton is provided with insulating high-temperature tape, which is used to help the insulation cotton better maintain the temperature at the connection point.

[0012] As a further description of the above technical solution:

[0013] The heating wire is used to heat the copper tube, and both ends of the heating wire are connected to the extruder temperature control system to adjust the extrusion plasticizing temperature.

[0014] As a further description of the above technical solution:

[0015] The nut is used to connect the extruder and the die.

[0016] As a further description of the above technical solution:

[0017] One end of the thermocouple is pre-embedded between the copper tube and the heating wire to detect temperature and is connected to the extruder temperature controller to achieve automatic temperature control.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, by winding heating wires around a copper tube, setting up thermocouples to monitor temperature, using nuts to connect the extruder and the die, wrapping with insulation cotton and insulating high-temperature tape, and leveraging the excellent flexibility of the copper tube itself, the connecting tube achieves functions such as precise temperature control, efficient insulation, and stable connection. This solves the problem that some extrusion connecting tubes are prone to deformation and rupture when subjected to high extrusion pressure, affecting the continuity and stability of production. The above structure effectively improves the pressure resistance performance. Attached Figure Description

[0025] 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.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a disposable extrusion connecting tube, comprising a copper tube 1. The copper tube 1 has good thermal conductivity, enabling rapid and uniform heat transfer to ensure a stable ambient temperature for the material inside the tube during extrusion, which is beneficial for material plasticization and extrusion. A heating wire 2 is wound around the side wall of the copper tube 1 to heat the copper tube 1 and provide the necessary heat for material extrusion. A thermocouple 6 is installed on the side wall of the copper tube 1, with one end of the thermocouple 6 embedded between the copper tube 1 and the heating wire 2. The thermocouple 6 is used to detect the real-time temperature of the copper tube 1 and converts the temperature signal into an electrical signal. After being connected to the extruder temperature controller, automatic temperature control can be achieved. When the detected temperature is lower than the set value, the extruder temperature control system will control the heating wire 2 to increase its heating power; conversely, if the temperature is higher than the set value, the temperature control system will reduce the power of the heating wire 2, thereby ensuring that the temperature inside the copper tube 1 is always maintained within a suitable range for material extrusion and plasticization. Screws are installed on both sides of the copper tube 1. The cap 4 is used to connect the extruder and the mold, and the copper tube 1 is flared to ensure that the cap 4 does not fall off. The cap 4 is used to connect the extruder and the mold. The side wall of the copper tube 1 is covered with heat insulation cotton 3. The inner wall of the heat insulation cotton 3 is attached to the heating wire 2. On the one hand, the heat insulation cotton 3 is used to maintain the temperature at the connection and reduce the heat loss to the surrounding environment, so that the heat generated by the heating wire 2 can be more effectively applied to the copper tube 1 and the material inside the tube, reducing energy consumption. On the other hand, it can prevent the risk of burns during operation. Since the temperature of the copper tube 1 and the heating wire 2 is high when the equipment is working, the heat insulation cotton 3 can act as a heat insulation layer to prevent operators from accidentally touching the high-temperature parts and getting injured. The outside of the heat insulation cotton 3 is covered with insulating high-temperature tape 5. The insulating high-temperature tape 5 is used to help the heat insulation cotton 3 better maintain the temperature at the connection, further enhancing the heat insulation effect and reducing heat leakage. At the same time, the insulating properties of the insulating high-temperature tape 5 can prevent the leakage of electric current from the heating wire 2 and other components from causing safety hazards to the operators, ensuring the safety of equipment operation and personnel operation.

[0027] Working Principle: When using this equipment, tightening nut 4 onto the corresponding interfaces of the extruder and die connects the extruder and die, ensuring that the material can smoothly enter the die from the extruder through the connecting pipe during extrusion, completing the extrusion molding process. Heating wire 2 is wound around the side wall of copper tube 1 to heat it. Both ends of heating wire 2 are connected to the extruder temperature control system, which adjusts the power of heating wire 2 to regulate the extrusion plasticizing temperature. When the extruder temperature control system receives a temperature adjustment command, it changes the current output to heating wire 2, causing it to generate different levels of heat to raise or lower the temperature of copper tube 1. One end of thermocouple 6 is embedded between copper tube 1 and heating wire 2, enabling real-time detection of the temperature of copper tube 1. Thermocouple 6 is connected to the extruder temperature controller, transmitting the detected temperature signal to it. The extruder temperature controller compares the preset temperature value with the actual temperature value fed back by thermocouple 6. If the actual temperature... If the current is lower than the preset value, the output current to the heating wire 2 will increase, causing the heating wire 2 to generate more heat and raising the temperature of the copper tube 1. If the actual temperature is higher than the preset value, the output current will decrease, reducing the heat generated by the heating wire 2, thereby achieving automatic temperature control and ensuring the stability of the extrusion plasticizing temperature. The insulation cotton 3 is sleeved on the side wall of the copper tube 1. The insulation cotton 3 has good heat insulation performance. On the one hand, it can reduce the loss of heat from the copper tube 1 to the external environment, maintain the temperature stability at the connection, and ensure the continuous and stable extrusion plasticizing process. On the other hand, it can prevent the risk of burns caused by the excessive surface temperature of the copper tube 1 during operation, playing a safety protection role. The insulating high-temperature tape 5 is placed on the outside of the insulation cotton 3, which can further assist the insulation cotton 3 in maintaining the temperature at the connection. The insulating high-temperature tape 5 can not only block heat from dissipating through the outside of the insulation cotton 3, but also play a certain insulation role, preventing safety accidents caused by leakage of components such as the heating wire 2. At the same time, it also protects the insulation cotton 3 and extends its service life.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
