Description

Technical Field

[0001] This utility model relates to the field of cable extruder technology, and in particular to an infrared heating and slotted heat dissipation screw barrel cable extruder. Background Technology

[0002] Cable is a general term for electrical cables and optical cables. Cables have many uses, mainly for control installation, connecting equipment, transmitting power and so on. They are a common and indispensable item in daily life. Cable processing usually involves three steps: drawing, stranding and wrapping. Wrapping is the process of extruding the material to be wrapped around the cable and then heating and cooling it.

[0003] A search revealed a Chinese patent with publication number CN201820230888.1 that discloses a rapid heating extruder for producing cable sheaths. The extruder uses a heating element to heat the material, and then a heating wire tightly wound along the length of the barrel is used to accelerate the heating process. The extruder has a simple structure, is easy to operate, and has high efficiency.

[0004] The above-mentioned technical solutions have the following drawbacks. In this type of traditional cable extrusion process, the extruder usually uses resistance wire heating or hot oil circulation for heating. However, these traditional heating methods have many shortcomings, such as low heating efficiency, high energy consumption, uneven heating, and limited heat dissipation performance of the screw barrel during extrusion, which can easily cause the material temperature to be too high, affecting the quality of the cable and the continuous working capacity of the extruder. Therefore, an infrared heating cable extruder with a slotted heat dissipation screw barrel is proposed.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This invention provides an infrared heating and slotted heat dissipation screw barrel cable extruder, which solves the problems mentioned in the background art, improves heating efficiency, reduces energy consumption, makes the extruder heating and heat dissipation more uniform, and improves the quality and production efficiency of extruded cables.

[0008] The present invention provides the following solution to the above-mentioned technical problems: An infrared heating and slotted heat dissipation screw barrel cable extruder includes a load-bearing base, a load-bearing frame, a stepper motor, a reducer, a feeding pipe, a feeding hopper, an extrusion screw, a screw barrel, an infrared heating coil, an infrared heating controller, a heat dissipation box, and a heat dissipation fan. The load-bearing frame and the infrared heating controller are fixedly installed on the top of the load-bearing base. The stepper motor and the reducer are both installed on the top of the load-bearing frame. The drive end of the stepper motor is connected to the reducer, and the other end of the reducer is fixedly connected to the extrusion screw. The reducer is fixedly connected to the feeding pipe, which is fixedly connected to the feeding hopper. The heat dissipation box is installed on the top of the infrared heating controller, which is connected to the infrared heating coil. The screw barrel is installed on the inner wall of the heat dissipation box, and the infrared heating coil is installed on the outer wall of the screw barrel. The heat dissipation fan is fixedly connected to the heat dissipation box. The screw barrel is fixedly connected to a cable extruder head. The outer wall of the screw barrel is uniformly provided with heat dissipation grooves, and the screw barrel is provided with temperature measuring holes.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the inner wall of the screw barrel is provided with an extrusion channel adapted to the extrusion screw, and the extrusion screw can rotate on the inner wall of the screw barrel, thereby driving the cable material to be extruded from the extrusion channel.

[0011] Furthermore, multiple infrared heating coils are provided, and the multiple infrared heating coils are evenly fitted on the outer wall of the screw barrel, so that the multiple infrared heating coils can evenly heat the cable material on the screw barrel and the inner wall.

[0012] Furthermore, the outer wall of the heat dissipation box is uniformly provided with heat dissipation holes, and the heat dissipation air of the heat dissipation fan can be transmitted from the heat dissipation holes in the heat dissipation box, thereby cooling the screw barrel and the cable material inside.

[0013] Furthermore, multiple cooling fans are provided, and the multiple cooling fans are evenly connected to the cooling box, so that the multiple cooling fans can evenly cool the screw cylinder inside the cooling box.

[0014] Furthermore, the heat dissipation box has a mounting hole corresponding to the screw cylinder, and the inner wall of the mounting hole is fixedly connected to the screw cylinder.

[0015] Furthermore, the infrared heating controller is equipped with a temperature detection module and a temperature detection probe, and the temperature detection probe is fixedly installed in the temperature measuring hole, and the connection is sealed, so that the infrared heating controller can detect the temperature of the raw material in the screw barrel in real time.

[0016] Furthermore, the outer wall of the screw barrel is provided with a feed port corresponding to the feed hopper. The feed pipe is connected to the screw barrel. The extrusion screw is transmitted from the screw barrel and connected to the reducer through the feed pipe. The cable raw material can be fed into the screw barrel through the feed port. The reducer can drive the extrusion screw to rotate inside the screw barrel.

[0017] This utility model provides an infrared heating and slotted heat dissipation screw barrel cable extruder, which has the following advantages:

[0018] 1. On the outer part of the screw barrel, holes for measuring temperature are specially designed and opened. The presence of these temperature measuring holes allows the temperature measuring element to directly contact the medium inside the screw barrel, thereby realizing direct temperature measurement of the medium. This direct measurement method is more accurate than the traditional indirect measurement method and can reflect the temperature change inside the screw barrel in real time, which makes it easier for the staff to adjust the temperature inside the screw barrel, thus ensuring the quality and production efficiency of the extruded cable.

[0019] 2. Multiple heat dissipation grooves are designed on the outer wall of the screw barrel. The depth and width of these grooves are carefully designed to maximize the heat dissipation area of ​​the screw barrel without affecting its structural strength. The grooves help improve the heat dissipation efficiency of the screw barrel, enabling it to quickly dissipate excess heat during extrusion, thereby maintaining a stable internal temperature and ensuring the quality of the extruded cable.

[0020] 3. The infrared heating coil is set on the outside of the screw and barrel, and heats the barrel by infrared radiation. Infrared heating has the advantages of fast heating speed, uniform heating and high thermal efficiency. Compared with traditional resistance wire heating or hot oil circulation heating, infrared heating can transfer heat to the inside of the barrel more quickly, shorten the heating time of the material, improve production efficiency, and has the characteristics of simple operation and low maintenance cost.

[0021] 4. Its compact structure and small footprint make it suitable for installation in limited spaces. In addition, the low outer surface temperature of the infrared heating coil reduces heat loss, making the working environment more friendly to operators during extrusion. It can effectively solve the problems of low heating efficiency, high energy consumption, and uneven heating in traditional extruders, significantly improving the quality and production efficiency of extruded cables, and has broad application prospects.
