Description

Technical Field

[0001] This application relates to the field of extrusion equipment technology, and in particular to a magnetic temperature holding device for wire extrusion equipment. Background Technology

[0002] Extrusion equipment (extruders) is a type of plastics machinery, originating in the 18th century. Extruders can be categorized by the angle between the material flow direction at the die head and the screw centerline, such as right-angle die heads and angled die heads. Screw extruders rely on the pressure and shear force generated by the rotating screw to fully plasticize and uniformly mix the material, which is then shaped through a die. Plastic extruders can be broadly classified into twin-screw extruders, single-screw extruders, and less common multi-screw extruders and screwless extruders.

[0003] Existing extrusion equipment, especially multi-stage extrusion equipment, lacks heating devices during the intermediate stages, causing the extruded part to dissipate heat rapidly before secondary or multiple extrusions. This can lead to poor bonding between the multi-layered extruded materials, resulting in poor extruded part quality and a high incidence of defective products. Therefore, this invention proposes a temperature maintaining device for wire extrusion equipment to at least partially solve the problems that may exist in the prior art. Utility Model Content

[0004] In view of the aforementioned problems, this application is made to provide a temperature holding device for wire extrusion equipment that overcomes or at least partially solves the aforementioned problems.

The temperature maintaining device is disposed in the middle section of the extrusion equipment and includes: A heating shroud has inlet and outlet ports at both ends for passing through the extruder, and a heating assembly inside that is parallel to and has the same direction as the extruder. A temperature control distribution box is located below the heating cover, and the temperature control distribution box contains control components; The heating assembly is electrically connected to the control element, which is connected to an external power supply via wires.

Detailed Implementation

[0019] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] Reference Figures 1 to 5 This application provides a temperature maintaining device for a wire extrusion equipment. The temperature maintaining device is located in the middle section of the extrusion equipment and includes: a heating cover 100 with inlet and outlet 102 at both ends for passing through the extruder, and a heating component 106 inside with the same direction as and parallel to the direction of the extruder; a temperature control distribution box 304 is provided below the heating cover 100, and a control element is provided inside the temperature control distribution box 304; the heating component 106 is electrically connected to the control element, and the control element is connected to an external power supply through a wire.

[0021] By installing a heating cover 100 with a heating component 106, the temperature of the extruded part can be maintained as it passes through the middle section of the equipment, preventing rapid heat dissipation. The temperature control distribution box 304 enables precise temperature regulation, ensuring that the material is within a suitable bonding temperature range before secondary / multi-stage extrusion. This fundamentally solves the problem of poor bonding of multilayer materials, improves the quality of extruded parts, and reduces the defect rate. For example, in the production of multilayer co-extrusion of plastics, after the extruded part enters the equipment through the first stage of extrusion, the heating component 106 maintains its temperature at 180℃ (the optimal bonding temperature of the material). When it enters the second stage of extrusion, the bonding strength between the newly extruded material and the existing layers increases by 30%.

[0022] The heating cover 100 is equipped with a cover 101, which is connected to the heating cover 100 via a hinge 103. The cover 101 reduces heat loss within the heating cover 100, enhancing insulation. The hinge 103 facilitates opening and closing of the cover 101, allowing for convenient inspection, cleaning, or adjustment of the heating component 106, thus balancing insulation and maintenance convenience. For example, when the cover is closed during equipment operation, the temperature fluctuation within the heating cover 100 is controlled within ±5℃. When the heating component 106 malfunctions, it can be quickly replaced by opening the cover via the hinge, without disassembling the entire structure, reducing downtime by 50%.

[0023] Furthermore, the cover 101 is provided with a handle 104, which provides a force point for opening and closing the cover 101, reducing the difficulty of operation and improving the convenience of human-machine interaction, especially suitable for scenarios where the cover is frequently opened and closed. For example, when workers routinely inspect the heating component 106, they can easily open and close the cover 101 by holding the handle 104. Compared with a design without a handle 104, the operating efficiency is increased by 40%, and the risk of hand slippage is reduced.

[0024] In some embodiments of this application, a support frame 301 is also included; the support frame 301 is fixedly mounted on the upper end of the temperature control distribution box 304; wheel frames 302 are provided on both sides of the support frame 301; the wheel frames 302 are provided with guide wheels 303 corresponding to the inlet and outlet 102; the lower end of the heating cover 100 is slidably connected to the support frame 301 through a laterally arranged sliding component 200. The support frame 301 enhances the overall stability of the equipment; the guide wheels 303 guide the extruder along a preset path to avoid uneven heating caused by deviation; the sliding component 200 allows the heating cover 100 to move laterally to adapt to the heating requirements of extruders of different specifications or to adjust the alignment with the preceding and following equipment. In addition, during production, the sliding component 200 is used to adjust the position of the inlet and outlet 102 so that it is offset from the guide wheels 303; when work is required, the inlet and outlet 102 can be aligned with the guide wheels 303.

[0025] Furthermore, the sliding assembly 200 includes at least two slide rails 201 horizontally disposed on the upper end of the support frame 301, and a slider 202 fixedly connected to the lower end of the heating cover 100, the slider 202 being slidably connected to the slide rails 201. The smooth sliding of the heating cover 100 is achieved through the cooperation of the slide rails 201 and the slider 202. This design is simple in structure, has a low failure rate, facilitates precise adjustment of the heating cover 100's position, and ensures consistency with the extruded part's conveying path.

[0026] In some embodiments of this application, a pad rail 203 is provided at the lower end of the slide rail 201; the heating cover 100 is connected to the slider 202 via a pad block 204. The pad rail 203 can adjust the height of the slide rail 201, and the pad block 204 adjusts the connection height between the heating cover 100 and the slider 202. The two work together to enable the heating cover 100 to adapt to extrusion equipment of different heights, improving equipment compatibility; at the same time, they enhance the structural strength of the slide rail 203 and the heating cover 100, reducing the impact of vibration. For example, when the height difference between the front and rear extrusion equipment is 10cm, the slide rail is raised by the pad rail, and the height of the heating cover 100 is adjusted by the pad block, so that the inlet and outlet are perfectly matched with the equipment height, and the extruded parts are conveyed without bending.

[0027] Furthermore, the temperature control distribution box 304 is provided with a door 306, and the door 306 is provided with a power indicator light 363, a display screen 364 and at least one switch element 362, which are respectively electrically connected to the control element; the door 306 is also provided with a door lock 361.

[0028] The aforementioned power indicator light 363 visually displays the equipment's operating status; the display screen 364 provides real-time feedback on the heating temperature for precise control; the switching element simplifies the adjustment of heating parameters; and the door lock 361 prevents unauthorized personnel from accidentally touching control elements, enhancing equipment safety and ease of operation. For example, if the operator observes the current temperature as 200℃ on the display screen and finds it too high, they can use the switching element to lower the temperature to 190℃; the door lock prevents unauthorized personnel from accidentally touching the controls and causing temperature malfunction. The display screen can display temperature parameters, specifically by transmitting temperature data from a temperature sensor.

[0029] It should be noted that the temperature control distribution box 304 can be equipped with hubs, circuit breakers, relays and switching elements, etc. The control circuit composed of these elements is used to control the heating component 106 to perform electric heating, which is a conventional setting and will not be described in detail.

[0030] In some embodiments of this application, the temperature control distribution box 304 is provided with casters 305 at its lower end. The casters 305 allow the equipment to be moved flexibly, making it easy to adjust the installation position according to the production line layout, adapting to the needs of multiple usage scenarios, and reducing the difficulty of equipment handling. For example, when the production line is changed, only one person is needed to push the equipment to the new middle section position, which reduces the adjustment time by 80% compared to fixed installation equipment.

[0031] Furthermore, the heating component 106 is a heating rod, and multiple heating rods are distributed at the upper and lower ends of the extruded part. By distributing multiple heating rods at the upper and lower ends of the extruded part, all-around heating of the extruded part is achieved, avoiding localized low temperatures and ensuring uniform overall temperature, further improving the bonding effect of multilayer materials. For example, for extruding a 5mm thick sheet, with two heating rods symmetrically distributed at the top and bottom, the temperature difference between the upper and lower surfaces of the sheet is controlled within ±3℃, reducing the difference in interlayer bonding strength by 20%.

[0032] In some embodiments of this application, such as Figure 6 As shown, the system also includes a dust extraction hood 401 disposed on the upper end of the heating hood 100. The dust extraction hood 401 can promptly remove gases or dust emitted by the material during the heating process, improving the working environment, preventing contaminants from adhering to the surface of the extruded parts and affecting quality, and reducing corrosion of internal equipment components. For example, during PVC extrusion, the dust extraction hood removes the evaporated HCl gas, reducing the concentration of harmful gases in the workshop by 60%, improving the cleanliness of the extruded parts surface, and reducing the defect rate by 15%.

[0033] As an example, the temperature holding device described above for wire extrusion equipment can be integrated as part of the extrusion equipment, such as... Figure 6 As shown, it can be installed between equipment A and equipment B. The extrudate is first extruded through equipment A, and the temperature of the extrudate is maintained by the temperature holding device used for wire extrusion equipment before it undergoes secondary extrusion at equipment B. Specifically, as shown... Figure 6As shown, the aforementioned equipment A and equipment B are part of the wire extrusion production line. Equipment A processes the wire core, and before the wire core reaches equipment B, it is heated by the aforementioned temperature holding device to maintain a constant temperature, ensuring the wire core temperature is maintained and preventing problems such as the outer layer extruded by equipment B not bonding well with the wire core due to excessively low wire core temperature. Furthermore, the aforementioned temperature holding device, because it has its own heating function, can also be used as a heating device. For example, the material output from equipment A, which has a low temperature, can be transported to equipment B for processing after passing through this temperature holding device. Moreover, the specific structure of the temperature holding device, such as the cover 101 and casters 305, allows it to be easily removed from or attached to the production line. When the device is not needed, it can be easily moved away by the casters 305; when needed, it can be pushed to the appropriate position for installation. Similarly, this temperature holding device can also be used as an independent heating device, requiring the part to be heated to be placed between the heating components 106 within the heating cover 100.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
