Description

Technical Field

[0001] The invention relates to the technical field of cooling equipment, in particular to an extrusion cooling equipment for high-performance plastics, and in particular to a molding process for the extrusion cooling equipment for high-performance plastics. Background Art

[0002] In the plastic extrusion production process, the material will first be melted at high temperature in the extruder and then extruded to obtain high-temperature material strips. The extruded material strips can only be input into the pelletizer for pelletizing after cooling and hardening, and then the next processing. In the plastic production equipment, the water tank filled with cooling water will cool down the high-temperature material strips just extruded, so that they will harden and obtain plastics with optimized strength, impact resistance, heat resistance, hardness and aging resistance.

[0003] Chinese patent CN219381545U discloses a highly efficient cooling device for extruded material of a plastic extruder, comprising a cooling pool corresponding to the extrusion port of a plastic extrusion die, a pretreatment unit installed at the upper end of the extrusion port of the plastic extrusion die, a plurality of conveying rollers evenly arranged in the cooling pool, a support roller is arranged between the conveying roller and the extrusion port, a water absorbing guide unit is arranged at one end of the cooling pool away from the extrusion port, and the extruded material is conveyed from the upper end of the support roller through the conveying roller and the cooling pool to the next processing unit through the water absorbing guide unit. When cooling the extruded material, the utility model achieves the stepwise cooling of the extruded material, avoids the high-temperature extruded material directly contacting with the cooling water of lower temperature to form a huge temperature difference, and improves the qualified rate of the extruded material. At the same time, the setting of the water level alarm, the thermometer and the control system improves the cooling efficiency of the cooling pool, and the degree of automation is high.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] See also Figures 1 to 10As shown, a high-performance plastic extrusion cooling device includes an extrusion temperature control cooling device installed at the discharge end of a plastic extruder 1, the extrusion temperature control cooling device includes a spiral extrusion head 2 installed at the discharge end of the plastic extruder 1, the spiral extrusion head 2 is connected to a kinetic energy conversion device 3, a temperature detector is installed inside the spiral extrusion head 2, and an air guide and heat dissipation mechanism 4 is also installed on the outside of the spiral extrusion head 2, the air outlet end of the air guide and heat dissipation mechanism 4 is coaxially arranged with the discharge end of the spiral extrusion head 2, the driving end of the air guide and heat dissipation mechanism 4 is transmission-connected with the kinetic energy conversion device 3, the kinetic energy conversion device 3 is provided with a multiple cooling and heat dissipation device 6, the liquid inlet end of the multiple cooling and heat dissipation device 6 is connected with the liquid outlet end of the kinetic energy conversion device 3, the kinetic energy conversion device 3, the discharge end of the multiple cooling and heat dissipation device 6 is installed with a circulating conveying pump 5, the liquid outlet end of the circulating conveying pump 5 is connected with the liquid inlet end of the kinetic energy conversion device 3, the extrusion temperature control cooling device also includes an intelligent control module, and the intelligent control module is connected to the temperature detector.

[0035] The extrusion temperature control cooling device is installed at the discharge end of the plastic extruder 1, and the spiral extrusion head 2 is connected to the discharge end of the plastic extruder 1. The staff then installs the extrusion molding head 11 to the discharge end of the spiral extrusion head 2. When the plastic extruder 1 is working, the heated and melted plastic is extruded and transported to the spiral extrusion head 2. When the hot-melt plastic passes through the spiral extrusion head 2, the internal temperature detector can effectively detect the temperature of the plastic. The intelligent control module analyzes the temperature detected by the temperature detector. To ensure that the extruded plastic is quickly cooled and formed, the intelligent control module can control the circulating delivery pump 5 to suck the coolant inside the multiple cooling and heat dissipation device 6 and transport it to the kinetic energy conversion device 3. The kinetic energy conversion device 3 then transports the transported coolant to the inside of the spiral extrusion head 2, which can effectively reduce the spiral extrusion head 2. The temperature of the spiral extrusion head 2 drops, which can effectively cool the plastic that passes through it, so that the plastic that passes through it maintains a suitable extrusion temperature, which is convenient for rapid molding. After the coolant cools the spiral extrusion head 2, the kinetic energy conversion device 3 then transports the coolant to the multiple cooling and heat dissipation device 6. The multiple cooling and heat dissipation device 6 will quickly cool the coolant and can be effectively recycled. When the coolant is transported to the kinetic energy conversion device 3, it will also drive the air guide and heat dissipation mechanism 4 to rotate. When the air guide and heat dissipation mechanism 4 rotates, it will guide the airflow to blow to the newly extruded plastic parts for cooling and shaping. The intelligent control module adjusts the delivery speed of the circulation delivery pump 5 by detecting the temperature of the extruded plastic, which is convenient for effectively controlling the temperature of the extruded plastic. Through this device, the cooling molding efficiency can be effectively improved, while reducing the cooling cost.

[0036] See also Figure 3 and Figure 5As shown, the spiral extrusion head 2 includes a conical mounting sleeve 21 installed at the discharge end of the plastic extruder 1, the discharge port of the conical mounting sleeve 21 is provided with a docking mounting port, a mounting bracket 22 is installed inside the conical mounting sleeve 21, and the mounting bracket 22 is also installed with a spiral cooling wheel 23.

[0037] The conical mounting sleeve 21 is used to be installed on the plastic extruder 1. When the plastic extruder 1 is working, the heated and melted plastic is transported to the inside of the conical mounting sleeve 21. The conical mounting sleeve 21 will guide the movement of the plastic. When the melted plastic moves inside the conical mounting sleeve 21, it is guided by the spiral cooling wheel 23 to effectively allow the plastic to pass through the gap between the conical mounting sleeve 21 and the spiral cooling wheel 23. When the melted plastic collides with the spiral cooling wheel 23, the temperature will be transferred to the spiral cooling wheel 23. The spiral cooling wheel 23 will cooperate with the flowing coolant to effectively cool down the plastic, and the plastic passing through the gap between the conical mounting sleeve 21 and the spiral cooling wheel 23 will be cooled synchronously, thereby effectively controlling the temperature of the extruded plastic.

[0038] See also Figures 5 to 7 As shown, the spiral cooling wheel 23 includes a conical rotating wheel 231 mounted on the mounting bracket 22, a conical guide surface 232 is provided at the opposite end of the conical rotating wheel 231, the outer side of the conical rotating wheel 231 is covered with spiral guide strips 233, a limiting guide sleeve 234 is installed inside the conical rotating wheel 231, a guide dividing plate 237 is provided outside the limiting guide sleeve 234, a cooling channel is provided at the gap between the limiting guide sleeve 234 and the conical rotating wheel 231, a liquid inlet pipe 235 and a liquid outlet pipe 236 are symmetrically provided on both sides of the guide dividing plate 237, and the ends of the liquid inlet pipe 235 and the liquid outlet pipe 236 away from the limiting guide sleeve 234 are both connected to the interior of the kinetic energy conversion device 3.

[0039] The conical guide surface 232 of the conical rotating wheel 231 can effectively guide the melted plastic to diffuse and move, so that the melted plastic flows to the gap between the conical mounting sleeve 21 and the conical rotating wheel 231. When the melted plastic flows to the gap between the conical mounting sleeve 21 and the conical rotating wheel 231, the melted plastic will squeeze the spiral guide strip 233 on the outer side of the conical rotating wheel 231. When the spiral guide strip 233 is squeezed, the conical rotating wheel 231 will rotate in a spiral. The outer wall of the conical rotating wheel 231 and the spiral guide strip 233 can effectively conduct heat energy. When the conical rotating wheel 231 needs to be cooled and dissipated, the liquid inlet pipe 235 The coolant flowing in the kinetic energy conversion device 3 is transported to the gap between the limiting guide sleeve 234 and the conical rotating wheel 231. The coolant can effectively perform liquid cooling on the conical rotating wheel 231. When the conical rotating wheel 231 is cooled, the extruded moving plastic will also be cooled. The rotation of the conical rotating wheel 231 can ensure the uniformity of cooling. The guide dividing plate 237 on the limiting guide sleeve 234 can effectively divide the cooling channel between the limiting guide sleeve 234 and the conical rotating wheel 231, so that the coolant entering from the liquid inlet pipe 235 circulates in the cooling channel and is then discharged from the liquid outlet pipe 236, which can effectively cool and dissipate heat.

[0040] See also Figures 3 to 6 As shown, the kinetic energy conversion device 3 includes a flow installation tube 31 installed on the conical installation sleeve 21, and the end of the flow installation tube 31 is provided with a liquid inlet pipe 235 and a liquid outlet pipe 236. The liquid inlet pipe 235 is connected to the liquid inlet pipe 235 of the spiral cooling wheel 23, and the liquid outlet pipe 236 is connected to the liquid outlet pipe 236 of the spiral cooling wheel 23. Both ends of the flow installation tube 31 are installed with a driving bevel gear 34, and the first spiral driving blade 35 is installed inside the driving bevel gear 34. The driving bevel gear 34 is connected to the circulating delivery pump 5. The kinetic energy conversion device 3 also includes a transmission bevel gear 36 installed on the outside of the conical installation sleeve 21, and the transmission bevel gear 36 is meshed with the driving bevel gear 34.

[0041] The liquid inlet pipe 235 and the liquid outlet pipe 236 inside the flow installation pipe 31 are connected to the liquid inlet pipe 235 and the liquid outlet pipe 236 of the spiral cooling wheel 23 respectively. When the coolant needs to be circulated and transported to the spiral cooling wheel 23, the circulating delivery pump 5 sucks the coolant in the multiple cooling and heat dissipation device 6 and transports the coolant to the liquid inlet pipe 235 inside the flow installation pipe 31. The liquid inlet pipe 235 can transport the coolant to the liquid inlet pipe 235 of the spiral cooling wheel 23, and the liquid outlet pipe 236 of the spiral cooling wheel 23 discharges the coolant to the flow installation pipe 31. In the liquid outlet pipe 236, the liquid outlet pipe 236 transports the used coolant to the multiple cooling and heat dissipation device 6. When the coolant enters the flow installation pipe 31, it will pass through the first spiral driving blade 35 inside the driving bevel gear 34. The flow force of the coolant will drive the driving bevel gear 34 to rotate. When the driving bevel gear 34 rotates, it will drive the transmission bevel gear 36 to rotate synchronously. When the transmission bevel gear 36 rotates, it will drive the air guide and heat dissipation mechanism 4 to rotate, effectively guiding the coolant into the spiral extrusion head 2 for circulation, while saving energy consumption and reducing cooling costs.

[0042] See also Figure 3 and Figure 4 As shown, the air guiding and heat dissipation mechanism 4 includes a mounting ring 41 mounted on the transmission bevel gear 36 , and the outer side of the mounting ring 41 is evenly spaced with fan blades 42 . The air guiding and heat dissipation mechanism 4 also includes an air guiding sleeve 43 mounted on the outer side of the conical mounting sleeve 21 .

[0043] The mounting ring 41 is used to connect the transmission bevel gear 36 of the kinetic energy conversion device 3. When the transmission bevel gear 36 rotates, it will drive the fan blades 42 to rotate synchronously. When the fan blades 42 rotate, the flow will be blown to the air guide sleeve 43. The air guide sleeve 43 guides the flowing air flow to the discharge port of the spiral extrusion head 2 to cool the extruded plastic parts.

[0044] See also Figure 4 and Figure 5 As shown, an air collecting scoop 431 is provided at one end of the air guide sleeve 43, and the air collecting scoop 431 is sleeved on the outside of the fan blade 42. An air uniformity guide head 432 is provided at the end of the air guide sleeve 43 away from the air collecting scoop 431. A conical air guide scoop is provided on the air uniformity guide head 432. A straight-outlet vent 433 is provided at the axial position of the conical air guide scoop. A spiral air guide outlet 434 is provided on the outer wall of the conical air guide scoop. A plurality of spiral air guide strips are provided inside the spiral air guide outlet 434. The spiral air guide outlet 434 is coaxially arranged with the straight-outlet vent 433.

[0045] The wind collecting scoop 431 of the wind guide sleeve 43 can effectively collect and guide the flowing airflow to converge and flow into the conical wind guide scoop, the straight outlet vent 433 of the conical wind guide scoop can effectively guide the flowing airflow to be discharged in a straight line, and the spiral air guide outlet 434 of the conical air guide scoop will form a spiral downward airflow blowing toward the extruded plastic parts. The spiral air guide outlet 434 and the straight outlet vent 433 can cooperate to effectively form a staggered flow of cooling gas to cool the plastic parts.

[0046] See also Figure 3 and Figure 8 As shown, the multiple cooling and heat dissipation device 6 includes a cooling box 61 installed next to the kinetic energy conversion device 3, a spiral heat dissipation cooling rack 62 is installed inside the cooling box 61, the spiral heat dissipation cooling rack 62 is connected to the circulating delivery pump 5, and an air-cooling heat dissipation mechanism 63 is installed at the bottom of the cooling box 61.

[0047] The cooling box 61 is filled with cooling liquid. When the kinetic energy conversion device 3 guides the used cooling liquid to the spiral cooling rack 62, the cooling liquid flows into the spiral cooling rack 62, and the spiral cooling rack 62 rotates. When the spiral cooling rack 62 rotates, the heat energy of the cooling liquid is transferred to the cooling liquid inside the cooling box 61. The cooling box 61 is filled with cooling liquid, which can effectively dissipate heat and cool down the spiral cooling rack 62, so that the coolant inside the spiral cooling rack 62 can be quickly cooled down. The air-cooled heat dissipation mechanism 63 at the bottom of the cooling box 61 can effectively dissipate heat and cool down the cooling liquid inside the cooling box 61. The cooling effect of the cooling liquid can be effectively ensured through multiple heat dissipation and cooling.

[0048] See also Figures 8 to 10 As shown, the spiral heat dissipation cooling rack 62 includes a conical flow bracket 621 installed inside the cooling box 61, the conical flow bracket 621 is provided with a plurality of flow heat dissipation tubes 622, the flow heat dissipation tubes 622 are provided with flow holes, a spoiler 623 is provided at the axial position of the conical flow bracket 621, and a second spiral driving blade 624 is installed at the liquid outlet end of the conical flow bracket 621.

[0049] The spiral heat dissipation cooling frame 62 is a stainless steel metal frame, and the circulation heat dissipation pipe 622 is made of copper. The coolant enters from the top of the spiral heat dissipation cooling frame 62 and is discharged from the bottom of the spiral heat dissipation cooling frame 62. When the coolant is discharged from the bottom of the conical circulation bracket 621, it will pass through the second spiral driving blade 624. When the coolant passes through the second spiral driving blade 624, the conical circulation bracket 621 will rotate. When the conical circulation bracket 621 rotates, it will drive the spoiler 623 and the circulation heat dissipation pipe 622 to rotate synchronously. When the circulation heat dissipation pipe 622 rotates, the circulation hole can effectively allow the heat dissipation liquid inside the cooling box 61 to pass quickly, and the circulation heat dissipation pipe 622 will quickly diffuse the heat energy into the heat dissipation liquid. The spoiler 623 can effectively cause the heat dissipation liquid inside the cooling box 61 to flow in a spiral, and the volatile heat dissipation effect can be effectively improved through the spiral heat dissipation cooling frame 62.

[0050] See also Figure 8 and Fig. 9 As shown, the air-cooled heat dissipation mechanism 63 includes an annular heat dissipation fin 632 installed at the bottom of the cooling box 61, and a plurality of heat pipes 631 are also installed on the annular heat dissipation fin 632. The heat pipes 631 extend into the interior of the cooling box 61. A conical air guide hole 633 is provided at the axial position of the annular heat dissipation fin 632. A fixed bracket 634 is also installed on the annular heat dissipation fin 632. A cooling supply fan 635 is installed on the fixed bracket 634. The cooling supply fan 635 is connected to the conical circulation bracket 621.

[0051] After the heat dissipation liquid inside the cooling box 61 dissipates heat and cools down the coolant, the heat dissipation liquid inside the cooling box 61 will rise steadily, and the heat pipe 631 will be inserted into the interior of the cooling box 61. The heat pipe 631 can effectively transfer heat energy to the annular heat dissipation fins 632, and the temperature of the annular heat dissipation fins 632 will rise. When the spiral heat dissipation cooling frame 62 rotates, it will drive the cooling supply fan 635 to rotate synchronously. When the cooling supply fan 635 rotates, it will drive the airflow to blow into the conical air guide holes 633 of the annular heat dissipation fins 632. The multi-layer annular heat dissipation fins 632 and the conical air guide holes 633 can effectively form a stepped diversion effect, which evenly diffuses the flowing airflow to cool the annular heat dissipation fins 632 and the heat pipes 631, thereby effectively ensuring the heat dissipation effect.

[0052] A molding process of an extrusion cooling device for high-performance plastics comprises the following steps;

[0053] S1, the extrusion temperature control cooling device is installed at the discharge end of the plastic extruder 1, the spiral extrusion head 2 is connected to the discharge end of the plastic extruder 1, and then the extrusion molding head 11 is installed at the discharge end of the spiral extrusion head 2. When the plastic extruder 1 is working, the heated and melted plastic is extruded and transported to the spiral extrusion head 2.

[0054] S2. When the hot-melt plastic passes through the spiral extrusion head 2, the internal temperature detector can effectively detect the temperature of the plastic. The intelligent control module analyzes the temperature detected by the temperature detector. To ensure that the extruded plastic is quickly cooled and formed, the intelligent control module can control the circulating delivery pump 5 to suck the coolant inside the multiple cooling and heat dissipation device 6 to deliver it to the kinetic energy conversion device 3. The kinetic energy conversion device 3 then delivers the delivered coolant to the inside of the spiral extrusion head 2, which can effectively reduce the temperature of the spiral extrusion head 2. The drop in the temperature of the spiral extrusion head 2 can effectively cool the plastic that passes through it, so that the plastic that passes through it maintains a suitable extrusion temperature, which is convenient for rapid molding.

[0055] S3. After the coolant cools down the spiral extrusion head 2, the kinetic energy conversion device 3 then transports the coolant to the multiple cooling and heat dissipation device 6. The multiple cooling and heat dissipation device 6 will quickly cool down the coolant and can be effectively recycled. When the coolant is transported to the kinetic energy conversion device 3, it will also drive the air guide and heat dissipation mechanism 4 to rotate. When the air guide and heat dissipation mechanism 4 rotates, it will guide the airflow to blow to the newly extruded plastic parts for cooling and shaping.

When the hot-melt plastic passes through the spiral extrusion head (2), the internal temperature detector can effectively detect the temperature of the plastic. The intelligent control module analyzes the temperature detected by the temperature detector. To ensure that the extruded plastic is quickly cooled and formed, the intelligent control module can control the circulating delivery pump (5) to suck the coolant inside the multiple cooling and heat dissipation device (6) and deliver it to the kinetic energy conversion device (3). The kinetic energy conversion device (3) then delivers the delivered coolant to the inside of the spiral extrusion head (2), which can effectively reduce the temperature of the spiral extrusion head (2). The decrease in the temperature of the spiral extrusion head (2) can effectively cool the plastic that passes through, so that the plastic that passes through maintains a suitable extrusion temperature, which is convenient for rapid molding.

The multiple cooling and heat dissipation device (6) will quickly cool the coolant and can be effectively recycled. When the coolant is delivered to the kinetic energy conversion device (3), it will also drive the air guide and heat dissipation mechanism (4) to rotate. When the air guide and heat dissipation mechanism (4) rotates, it will guide the airflow to blow toward the newly extruded plastic parts to cool and shape them. The intelligent control module adjusts the delivery speed of the circulation delivery pump (5) by detecting the temperature of the extruded plastic, so as to effectively control the temperature of the extruded plastic and improve the efficiency of cold forming.
