Description

Technical Field

[0001] This utility model relates to the field of wire and cable processing technology, and in particular to an extrusion device for wire and cable processing with a crushing function. Background Technology

[0002] Electric wires and cables are key electrical materials used for power transmission, distribution, and signal transmission, and are widely used in construction, industry, transportation, and other fields. They mainly consist of a conductor and an insulation layer, and may also include a shielding layer, armor layer, and outer sheath depending on functional requirements. The conductor is usually copper or aluminum due to its good conductivity; while the insulation layer is made of materials such as polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE) to ensure the safe transmission of current.

[0003] When extruding cables, uncrushed raw materials (especially recycled materials or large pieces) can lead to inconsistent melting states during extrusion, affecting the quality of the final product. Inconsistent particle size results in varying degrees of heating and plasticization, potentially causing uneven structure in the finished product. Larger materials require longer to fully melt, reducing extrusion speed and impacting overall production efficiency. Furthermore, larger materials can cause feeding difficulties into the extruder, increasing the risk of blockages.

[0004] Therefore, it is necessary to design an extrusion device for wire and cable processing with a crushing function to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, this utility model provides an extrusion device for wire and cable processing with a crushing function.

[0006] Technical Solution: An extrusion device for wire and cable processing with crushing function includes a support, a conveying cylinder, a variable speed motor, a spiral conveying rod, a heating chamber, a temperature controller, heating tubes, an annular extrusion cavity, and a crushing component. The conveying cylinder is fixedly connected to the middle of the support, and a feed inlet is opened at the top of the conveying cylinder. The variable speed motor is fixedly connected to the left side of the conveying cylinder. The output shaft of the variable speed motor passes through the conveying cylinder and is fixedly connected to the spiral conveying rod, which rotates inside the conveying cylinder. The heating chamber is fixedly connected to the outside of the conveying cylinder, and the temperature controller is fixedly connected to the front of the conveying cylinder. Multiple heating tubes are fixedly connected in an axial array between the conveying cylinder and the heating chamber. All heating tubes are electrically connected to the temperature controller. The bottom of the conveying cylinder is connected to and communicates with the annular extrusion cavity, and the crushing component is provided at the top of the conveying cylinder.

[0007] Optionally, the crushing assembly includes a buffer hopper, a discharge hopper, a first servo motor, crushing rollers, and gears. The feed inlet of the conveying cylinder is connected to and communicates with the buffer hopper, the top of the buffer hopper is connected to and communicates with the discharge hopper, the front of the discharge hopper is fixedly connected to the first servo motor, and the discharge hopper has crushing rollers rotatably connected to both sides inside the discharge hopper. One side of the crushing roller is fixedly connected to the output shaft of the first servo motor, and the rear of both crushing rollers extends out of the discharge hopper and is fixedly connected to meshing gears.

[0008] Optionally, both crushing rollers are provided with multiple meshing crushing teeth on their exteriors.

[0009] Optionally, it also includes an air pump, a U-tube, and a drain valve. The air pump is connected and communicated to the right side of the buffer hopper, the U-tube is connected and communicated to the top of the air pump, and the drain valve is connected and communicated to the front side of the U-tube.

[0010] Optionally, it also includes a mounting bracket, a second servo motor, and extrusion wheels.

[0011] Optionally, the outer surfaces of the two extrusion rollers are provided with grooves of a size suitable for the cable cores.

[0012] The beneficial effects of this utility model are: 1. This utility model drives the right crushing roller to rotate through the first servo motor, and the left crushing roller rotates synchronously in the opposite direction by means of the meshing gears, which ensures that the raw material is effectively crushed into smaller particles, improves the uniformity and efficiency of subsequent processing, and the setting of the buffer hopper reduces the impact force when the raw material enters the conveying cylinder, avoids blockage, ensures a smooth and stable feeding process, improves production efficiency, and also enhances the stability and reliability of equipment operation.

[0013] 2. This utility model uses an air pump to extract high-temperature gas from the device and send it into a U-shaped tube to purify it by contacting water. It effectively absorbs or dissolves harmful components such as volatile organic compounds (VOCs) and particulate matter. The U-shaped tube ensures that the gas must pass through the water layer before it can be discharged, which significantly reduces pollutant emissions and protects the environment.

[0014] 3. This utility model uses a second servo motor to drive the lower extrusion roller to rotate. The symmetrically arranged extrusion rollers apply appropriate pressure to the cable core, achieving automatic traction and maintaining its straightness and stable movement. The extrusion rollers not only ensure that the cable core passes smoothly through the annular extrusion cavity, but also assist in uniformly wrapping the molten insulation material around the outside of the cable core, ensuring consistent insulation layer thickness and smooth surface.

Detailed Implementation

[0021] Example: An extrusion device for processing wires and cables with a crushing function, such as... Figures 1-6As shown, the system includes a support frame 1, a conveying cylinder 4, a variable speed motor 41, a spiral conveying rod 42, a heating chamber 5, a temperature controller 51, a heating tube 52, an annular extrusion chamber 6, a buffer hopper 3, a discharge hopper 2, a first servo motor 21, a crushing roller 22, and gears 23. The conveying cylinder 4 is screwed onto the middle of the support frame 1. A feed inlet is located on the top left side of the conveying cylinder 4. The variable speed motor 41 is screwed onto the left side of the conveying cylinder 4. The output shaft of the variable speed motor 41 passes through the conveying cylinder 4 and is welded to the spiral conveying rod 42, which rotates within the conveying cylinder 4. A heating chamber 5 is welded to the outer wall of the conveying cylinder 4. A temperature controller 51 is screwed onto the front left side of the conveying cylinder 4. Multiple heating elements are screwed onto the conveying cylinder 4 and the heating chamber 5 in an axial array between them. Heat pipes 52, multiple heating pipes 52 are electrically connected to temperature controller 51. The bottom right side of the conveying cylinder 4 is connected to and communicates with an annular extrusion chamber 6. When this device is needed, the raw materials of the wires and cables to be processed are first added to the conveying cylinder 4 through the feed inlet. These materials may include raw granules, recycled materials, or large pieces. The variable speed motor 41 is started, and its output shaft drives the spiral conveyor 42 to rotate. The spiral conveyor 42 pushes the raw materials forward along the conveying cylinder 4. The heating pipes 52 are started by temperature controller 51, and heat is transferred to the raw materials in the conveying cylinder 4 through the heating chamber 5. Temperature controller 51 monitors and adjusts the temperature in the heating chamber 5 in real time to ensure that the raw materials are heated evenly and reach the required melting state. Under the continuous action of the conveyor rod 42, the raw material is continuously pushed to the end of the conveyor cylinder 4. During this process, it gradually plasticizes into a fluid melt. When the raw material is completely plasticized, the molten material enters the annular extrusion cavity 6. The material is subjected to further pressure and shape constraints to form the required cable insulation layer. The cable core is pulled through the annular extrusion cavity 6, and the extruded cable insulation layer wraps around the cable core, thus completing the cable processing. The feed inlet of the conveyor cylinder 4 is connected to and connected to a buffer hopper 3. The top of the buffer hopper 3 is connected to and connected to a discharge hopper 2. The first servo motor 21 is installed on the front right side of the discharge hopper 2 by screws. Crushing rollers 22 are rotatably connected to both the left and right sides inside the discharge hopper 2. The outer surfaces of the two crushing rollers 22 are provided with multiple meshing crushing teeth. The crushing roller 22 on the right side is fixedly connected to the output shaft of the first servo motor 21. The rear ends of both crushing rollers 22 extend out of the feed hopper 2 and are welded with meshing gears 23. When the raw material is poured into the feed hopper 2, the first servo motor 21 is started, and its output shaft drives the crushing roller 22 on the right side to rotate. The meshing gears 23 cause the crushing roller 22 on the left side to rotate synchronously in the opposite direction. The raw material entering the feed hopper 2 is clamped by the two relatively rotating crushing rollers 22 and crushed into smaller particles or fragments, ensuring that the subsequent processing is more uniform and efficient. After preliminary crushing, the raw material flows smoothly into the feed inlet of the conveying cylinder 4 through the buffer hopper 3 to feed the extrusion. The buffer hopper 3 can reduce the impact force when the raw material enters the conveying cylinder 4 and avoid blockage.

[0022] like Figures 1-6 As shown, it also includes an air pump 7, a U-shaped pipe 71, and a drain valve 72. The air pump 7 is connected to and communicates with the right side of the buffer hopper 3. The top of the air pump 7 is connected to and communicates with the U-shaped pipe 71. The front side of the U-shaped pipe 71 is connected to and communicates with the drain valve 72. First, water is poured into the U-shaped pipe 71. Then, the air pump 7 is started to draw the high-temperature gas generated inside the device into the U-shaped pipe 71 to contact the water for purification. Its function is to extract the high-temperature gas generated inside the device due to the heating process from the buffer hopper 3. This high-temperature gas is sent into the U-shaped pipe 71 through the air pump 7 to contact the water for purification. The gas is first exposed to water. Harmful components in the gas, such as volatile organic compounds (VOCs) and particulate matter, are absorbed or dissolved as they pass through the water, thus achieving purification. The U-shaped tube 71 ensures that the gas must pass through the water layer before it can be discharged, effectively removing most pollutants. The purified gas is discharged from the top of the U-shaped tube 71, reducing environmental pollution. Regularly check and use the drain valve 72 to drain the wastewater in the U-shaped tube 71 to prevent excessive accumulation from affecting the purification effect. Replace or add clean water as needed to ensure purification efficiency.

[0023] like Figure 3 As shown, the system also includes a mounting bracket 8, a second servo motor 81, and extrusion rollers 82. The mounting bracket 8 is welded to the rear right side of the bracket 1. The second servo motor 81 is mounted on the right side of the mounting bracket 8 via screws. The mounting bracket 8 is symmetrically connected to the extrusion rollers 82 in a rotating manner. The outer surfaces of the two extrusion rollers 82 have grooves of a size suitable for the cable cores. The lower extrusion roller 82 is fixedly connected to the output shaft of the second servo motor 81. Driving the second servo motor 81, the output shaft of which drives one of the extrusion rollers 82 to rotate, allows the cable core to contact the extrusion roller 82, automatically pulling the cable core through the annular extrusion cavity 6. The extruded cable insulation layer then wraps around the cable core, thus completing the cable insulation process. The second servo motor 81 is started, and its output shaft drives the lower extrusion roller 82 to rotate. Since the two extrusion rollers 82 are symmetrically arranged and in close contact, they can apply appropriate pressure to the cable core. The cable core is placed near one of the extrusion rollers 82, and the friction between the extrusion rollers 82 is used to automatically pull the cable core through the annular extrusion cavity 6. The extrusion roller 82 not only plays a traction role, but also helps the cable core maintain straightness and smooth movement. When the cable core is automatically pulled through the annular extrusion cavity 6, the molten insulation material is extruded and evenly wrapped around the outside of the cable core. The extrusion roller 82 also plays a certain shaping role in this process to ensure that the extruded insulation layer has a uniform thickness and a smooth surface.
