Description

Technical Field

[0001] The present invention relates to the technical field of yarn production, in particular to a device for intelligently melting and heating plastic particles for yarn production. Background Art

[0002] Traditional equipment lacks a dynamic material turning mechanism. After being crushed, plastic particles tend to accumulate locally in the heating area, resulting in uneven heating contact area. Some equipment only relies on gravity to feed the materials without actively stirring the particles, which increases the melt temperature deviation and the breakage rate caused by uneven melting during the drawing process. In addition, the traditional crushing mechanism has rough control over the particle size. The specific surface area of ​​larger particles is small, and the heating time needs to be extended, which not only increases energy consumption but also easily causes small particles to over-melt and degrade.

[0003] Existing heating equipment mostly uses a single heating method and lacks a real-time temperature feedback mechanism, making it difficult to accurately control the melting range of plastic particles. If the temperature of PET particles is lower than 240°C when melting, it will lead to poor plasticization, and if it is higher than 260°C, thermal oxidation degradation is likely to occur. However, traditional equipment cannot dynamically adjust the heating power according to the material state, and the melt quality stability is insufficient, affecting the uniformity of the filaments in subsequent extrusion molding.

[0004] The discharge structure of traditional equipment is mostly vertical discharge, and the melt is easy to remain and solidify in dead corners, which increases the cleaning time when changing materials; the extrusion link lacks a pressure monitoring device, and the extrusion pressure fluctuation increases, resulting in an increase in the filament diameter deviation. In addition, the curing mechanism mostly uses static water cooling, the filament curing speed is slow, and the cooling is uneven, resulting in uneven stress distribution in the filament and an increased risk of breakage during the twisting process. Summary of the Invention

[0016] Compared with the prior art, the present invention provides an intelligent melting and heating device for plastic particles in yarn production, which has the following beneficial effects: 1. This yarn production equipment is used for intelligent melting and heating of plastic particles. The turning mechanism drives the reel-up and unwinding chain through a rotating motor, which drives the folding and unfolding of the stacked sheets. The electric cylinder drives the pusher block to move horizontally, realizing the triple action of "turning-pushing-spreading" of the material. This design can evenly distribute the crushed plastic particles in the heating area, avoiding uneven heating caused by local accumulation, improving the consistency of the melt temperature, and significantly reducing the problem of wire drawing breakage caused by uneven melting. The feeding crushing mechanism crushes the plastic particles into fine particles, and the dynamic stirring of the turning mechanism increases the specific surface area of ​​the particles, improves the heating contact area, and thus shortens the melting time.

[0017] 2. The yarn production equipment is used for intelligent melting and heating of plastic particles. The heating component uses a temperature sensor to monitor the material temperature in real time to ensure that the plastic particles melt in the optimal temperature range, avoiding high-temperature degradation or poor plasticization at low temperatures. While the turning mechanism continuously turns the material, the heating element evenly supplies heat through the outer shell interlayer, forming a "turning-heating-turning again" cycle, which improves the uniformity of the melt temperature and provides a stable material basis for subsequent extrusion molding.

[0018] 3. The yarn production equipment is equipped with intelligent melting and heating equipment for plastic particles. The inclined design of the sloped discharge port uses gravity to assist the melt flow and reduce dead corner residue. The gear pump of the extrusion component cooperates with the pressure monitoring and control component to monitor and adjust the extrusion pressure in real time to ensure that the filament diameter deviation is reduced. The filament curing mechanism rotates the inner trapezoidal pipe through the rotating motor, combined with the spiral water flow cooling of the water injection pipe, to increase the filament curing speed and ensure good curing uniformity. The water tank of the shaping component cooperates with the wire roller to further stabilize the filament structure and reduce the risk of breakage in the subsequent twisting process.

The water injection pipe 63 is set at the end with the smaller inner diameter of the inner trapezoidal pipe 621. The rotating motor 4 61 drives the inner trapezoidal pipe 621 to rotate. The water injection pipe 63 injects ice particles into the end with the smaller inner diameter of the pipe. The ice particles lower the surface temperature of the entire inner trapezoidal pipe 621 along the inner trapezoidal pipe, and the inner trapezoidal pipe 621 quickly cools and solidifies the filaments.

After the ice particles melt, they are discharged from the drain pipe 623 and new ice particles are injected again through the water injection pipe 63. The solidified filaments enter the shaping component 7 through the outer surface of the connecting pipe 622. like Figure 9 As shown, the shaping assembly 7 includes a water tank 71, a rotating motor 72 and a wire roller 73.

[0024] Working principle: Figures 1-10 As shown, plastic particles are fed and crushed: plastic particles are poured from the feed hopper 21 and fall into the crushing box 221; the rotary motor 222 drives the spiral cutter 223 to rotate at high speed, crushing the particles into fine particles through shearing and extrusion; the crushed particles fall into the interior of the shell 1 through the bottom opening of the crushing box, preparing for subsequent melting; Material turning and uniform distribution: After the turning mechanism 3 is started, the rotary motor 31 drives the reel 32 to rotate, and the winding chain 331 pulls the stacked sheets 332 to unfold, pushing the pusher block 35 to move horizontally within the housing; the electric cylinder 34 controls the pushing force of the pusher block to evenly spread the crushed particles in the heating area; at the same time, the folding component 33 realizes the up and down turning of the material through the folding action of the winding chain and the stacked sheets, avoiding local accumulation and ensuring uniform heating; Intelligent heating and melting: A heating element 91 is embedded in the outer shell interlayer and heats the internal material through electromagnetic induction or resistance heating. A temperature sensor 92 monitors the material temperature near the turning mechanism in real time and transmits the data to a temperature control display 94. A spring valve 93 is controlled by the temperature signal. When the material melts into a fluid state, the valve automatically opens, allowing the melt to flow into the sloped discharge port 4. Melt extrusion and pressure control: The melted plastic flows into the extrusion assembly 5 along the sloped outlet 4; the rotary motor 51 drives the gear pump 52 to operate, pressurizing the melt and conveying it to the extrusion hood 54; the pressure sensor 531 monitors the pressure in the pump in real time, and the pressure display 532 feeds back to the control panel 10, automatically adjusting the motor speed to stabilize the pressure; the spinneret in the extrusion hood 54 extrude the melt into filaments; Filament solidification and shaping: The extruded filament is rolled onto the surface of the filament solidification mechanism 6, and the rotating motor 4 61 drives the inner trapezoidal pipe 621 to rotate. The water injection pipe 63 injects ice particles into the end of the pipe with a smaller inner diameter. The ice particles lower the surface temperature of the entire inner trapezoidal pipe 621 along the inner trapezoidal pipe, and the inner trapezoidal pipe 621 quickly cools and solidifies the filament. Since the inner diameter of the inner trapezoidal pipe gradually increases from right to left, the temperature gradually rises, ensuring uniform cooling of the filament. After the ice particles melt, they are discharged from the drain pipe 623, and new ice particles are injected again through the water injection pipe 63. The solidified filament passes through the outer surface of the connecting pipe 622 and enters the shaping component 7. Filament shaping and collection: The water tank 71 of the shaping component 7 is filled with cooling water, and the filaments are immersed in the water for further shaping; the rotary motor 5 72 drives the line roller 73 to rotate, and the filaments are wound around the line roller 73; by adjusting the rotation speed of the line roller 73 to match the extrusion speed, the tension and winding density of the filaments are controlled, and finally a regular chemical fiber roll is formed, which is convenient for subsequent twisting, dyeing and other processes.
