[0026] In the embodiments of the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0027] In the present utility model, as Figures 1 - 4 shown, an extruder for uniformly hot-melting materials is provided, including: a bottom plate 1, a main machine 101 is provided on the top of the bottom plate 1, a feeding pipe 2 is provided on one side of the main machine 101, and a feeding port 201 is opened on one side of the top of the feeding pipe 2; a feeding assembly, which is arranged on one side of the main machine 101 and is used to drive the material to be fed inside the feeding pipe 2; a hot-melting assembly, which is arranged inside the feeding pipe 2 and is used to quickly hot-melt the conveyed material; and a wrapping assembly, which is arranged at the end of the feeding pipe 2 and is used to quickly wrap the wire.

[0028] Furthermore, the feeding assembly includes: a driving motor 102 provided on the top of the main machine 101, a driving wheel 103 is provided on one side of the driving motor 102; a power rod 104 rotatably connected inside the main machine 101, a auger 105 is provided on one side of the power rod 104, and the edge of the auger 105 is in contact with the inner wall of the feeding pipe 2.

[0029] During the use process, the material enters the feeding pipe 2 from the feeding port 201. The main machine 101 drives the driving wheel 103 through the driving motor 102, and then drives the auger 105 to rotate through the power rod 104, and the material is pushed forward by the rotation of the auger 105. The design of the auger can ensure that the material enters the inside of the feeding pipe 2 evenly and continuously.

[0030] Furthermore, a feeding sleeve 202 is provided on the top of the feeding port 201. The feeding sleeve 202 is arranged in a funnel-shaped structure. During the use process, the funnel-shaped structure of the feeding sleeve 202 facilitates the introduction of the material and can improve the convenience of use of the device.

[0031] Furthermore, the hot-melting assembly includes: a heating kit 3 provided on one side of the feeding pipe 2, a plurality of electric heating tubes 301 are provided inside the heating kit 3, and the plurality of electric heating tubes 301 are arranged around the feeding pipe 2; a protection tube 302 provided on the outer surface of the electric heating tube 301, and the protection tube 302 is made of an insulating and heat-conducting ceramic material.

[0032] During use, the heating element 301 in the heating kit 3 heats the material in the feeding pipe 2. By using multiple heating elements 301, the uniformity of heating is ensured. At the same time, the protection pipe 302 prevents the heating element 301 from coming into direct contact with the outside world and causing electric leakage and other situations.

[0033] Furthermore, a flow-through pipe 303 is provided inside the heating kit 3, and the flow-through pipe 303 is filled with heat-conducting oil. The flow-through pipe 303 is divided into two parts, and the two parts of the flow-through pipe 303 are respectively located inside the feeding pipe 2 and the heating kit 3. A circulation pump 304 is provided inside the flow-through pipe 303.

[0034] During the heating process, the circulation pump 304 can pump the heat-conducting oil inside the flow-through pipe 303 to flow. At this time, the continuously flowing heat-conducting oil will absorb the heat inside the heating kit 3 and continuously conduct it into the flow-through pipe 303. Since the heating is not directly carried out by the heating element 301, the heat of the heat-conducting oil and the material in the feeding pipe 2 will not be as high as that of the heating kit 3, but will be preheated in a relatively medium-temperature environment. During the preheating process, the material can be softened in advance, and the material in the middle position can also obtain more heat in advance for softening, so as to facilitate the subsequent heating process, make the material be heated more quickly and evenly, prevent some materials from overheating while the materials in the middle part are not hot enough, resulting in insufficient melting and waste of materials, and avoid the defect of poor subsequent wrapping effect, and improve the melting sufficiency of the device and the effectiveness of finished product wrapping.

[0035] Furthermore, the wrapping assembly includes: a wire threading platform 4 provided at the end of the feeding pipe 2, and the inside of the wire threading platform 4 is in communication with the inside of the feeding pipe 2; an inlet 401 and an outlet 403 respectively opened on both sides of the wire threading platform 4 for the wire to pass through. A guiding plate 404 is provided at the connecting part between the inside of the wire threading platform 4 and the feeding pipe 2. The guiding plate 404 is inclined upward, and the end of the guiding plate 404 is higher than the inlet 401 and the outlet 403.

[0036] During use, the wire enters the wire threading platform 4 from the inlet 401. At this time, under the action of the guiding plate 404, the wire contacts the molten material and is wrapped. After the wrapping is completed, the wire is sent out from the outlet 403, thus completing the work of material wrapping. The inclined guiding plate 404 can make the material pour down from above the wire. When the inside of the wire threading platform 4 is not filled with material, it can effectively prevent the situation that some positions of the wire cannot be effectively wrapped, and improve the uniformity of feeding and wrapping of the device.

[0037] Further, a plurality of auxiliary rollers 402 are provided on the inner wall of the wire inlet 401, and the plurality of auxiliary rollers 402 are arranged at equal intervals along the circumferential direction of the inner wall of the wire inlet 401. The auxiliary rollers 402 can be used to guide and position the wire, so that the wire is located at the center of the wire inlet 401. After being wrapped with the material and passing through the wire outlet 403, it can be ensured that the wire is also located at the center of the wire outlet 403, so that the thickness of the surface wrapping of the wire is consistent, and the uniformity of the wrapping is further improved.

[0038] Further, a control console 5 is provided on one side of the main machine 101. The control console 5 is electrically connected to the drive motor 102, the electric heating tube 301 and the circulation pump 304. Temperature sensors 501 are provided inside the feeding pipe 2, the heating kit 3 and the wire threading table 4, and the temperature sensors 501 are in signal connection with the control console 5.

[0039] During the use process, the control console 5 monitors the temperature of the entire system in real time through the temperature sensors 501, and adjusts the working states of the drive motor 102, the electric heating tube 301 and the circulation pump 304 based on this. The real-time temperature monitoring helps to maintain the stability of the entire processing process. At the same time, the working parameters of each component can be flexibly adjusted through the control console 5 to meet the requirements of different materials and processes.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
