Description

Technical Field

[0001] The invention relates to the technical field of plastic processing, in particular to an anti-blocking peek extruder. Background Art

[0002] When processing high-viscosity melts, traditional PEEK extruders often experience screw channel blockage due to localized temperature unevenness or impurity accumulation, necessitating frequent shutdowns for cleaning. While increasing the screw pitch or speed can temporarily alleviate blockage, this exacerbates shear thermal runaway of the melt and causes thermal degradation of the material. External vibration-based declogging devices are complex and difficult to adapt to high-temperature and high-pressure operating conditions. Furthermore, impurities such as metal shavings and carbon fiber mixed in recycled PEEK waste tend to accumulate at the extrusion nozzle, requiring frequent replacement of traditional filters, severely impacting production efficiency.

[0003] Currently available anti-blocking solutions mostly rely on static heating or mechanical unblocking, using constant-power electric heating coils for heating. They are unable to dynamically adjust the temperature according to changes in melt pressure, resulting in insufficient melt fluidity at low speeds. Therefore, we propose an anti-blocking peek extruder to solve this problem. Summary of the Invention

[0017] The beneficial effects of the present invention are:

[0018] The cam is driven by the spring to move the feed roller to the feed end, and the ... The scraper and the spiral auger rotate, and the scraper and the rotating frame can stir the engineering plastic particles when they rotate. When the spiral auger rotates, it applies a downward thrust to the engineering plastic, so that it enters the extrusion barrel, so that the plastic particles are evenly distributed and hollows are avoided. When the spiral auger is subjected to resistance from the plastic particles, it pushes the rotating shaft to drive the connecting disk and the lifting disk to move upward, and squeezes the second pressure sensor, so that the compaction degree of the plastic can be judged by the second pressure sensor. When the pressure is greater than the preset value, the controller controls the output shaft of the rotating motor to decelerate the rotation to avoid blockage. When the pressure value monitored by the second pressure sensor is less than the preset value, the controller controls the output shaft of the rotating motor to accelerate the rotation, thereby accelerating the transportation of the plastic particles, so that the plastic particles are evenly distributed in the extrusion barrel. Then the extrusion auger transports the plastic particles horizontally and further heats the plastic particles through the second heating ring. The heated molten plastic is extruded from the extrusion hole and the extrusion nozzle. The main shaft drives the horizontal axis and the lever to rotate to improve the distribution uniformity of the molten plastic.

[0019] 2. In the present invention, the anti-clogging peek extruder monitors the temperature of the molten plastic through a temperature sensor, and controls the temperature of the first heating ring and the second heating ring through a controller to make corresponding adjustments. When the rotational resistance of the extrusion auger and the main shaft increases, the distance the linkage plate moves to the right increases, and drives the conductive cylinder to move synchronously. When the rotational resistance is large enough, the two conductive cylinders are sleeved on the outside of the corresponding resistor bar, so that the circuit of the energy storage power supply and the U-shaped electric heating rod is connected. The current is introduced into the first arc-shaped conductive plate through one of the conductive cylinders and the resistor bar. The first arc-shaped conductive plate guides the current to the U-shaped electric heating rod by abutting with the first conductive ring, and then passes through the second conductive ring, the second arc-shaped conductive plate and another set of conductive cylinders and resistors. The strip returns to the negative pole of the energy storage power supply to form a loop. When the current flows through the U-shaped electric heating rod, it emits heat to heat the main shaft and spiral auger, thereby heating the plastic to prevent its temperature from being too low to affect the fluidity, and to prevent cooling and condensation on the surface of the extrusion auger to cause blockage. At the same time, as the resistance to the extrusion auger increases, the two conductive cylinders move further to the right, and the length of the two resistance strips connected to the circuit becomes shorter, so that the current flowing through the U-shaped electric heating rod increases, and its heat generation increases, thereby improving the heating effect on the plastic and avoiding blockage. When the resistance to the rotation of the extrusion auger is too large, the linkage plate drives the pressing rod to press the touch button, so that the drive motor and the rotating motor are controlled by the controller to stop running, thereby performing shutdown maintenance;

[0020] 3. In the present invention, the anti-blocking peek extruder adjusts the extrusion speed by adjusting the output shaft speed of the driving motor, and the main shaft drives the mounting frame to rotate synchronously, and drives the centrifugal plate to perform circular motion. The centrifugal plate is thrown outward under the action of centrifugal force and squeezes the compression spring. When the rotation speed of the main shaft is large enough, it drives the connecting column to be inserted into the linkage groove, thereby driving the linkage ring and the turntable to rotate synchronously with the main shaft. When the rotating disk rotates, it drives multiple mounting seats to perform circular motion, thereby driving the coil and the electric heating plate to perform circular motion, and the closed coil continuously cuts the magnetic flux lines generated by the permanent magnet, thereby generating an induced electromotive force, thereby generating an induced current in the electric heating plate, causing it to heat up, thereby heating the turntable, thereby being able to simultaneously improve the heating effect of the plastic during high-speed extrusion, and monitoring the pressure on the extrusion nozzle through the second pressure sensor. When the pressure received by the second pressure sensor is too large, the speed of the driving motor is controlled to be reduced to avoid blockage.

[0021] 4. In the present invention, the anti-clogging peek extruder, through the synergistic effect of the linkage mechanism and the driving mechanism, realizes the dynamic perception and adaptive adjustment of the resistance during the extrusion process, effectively solving the technical problem that high-viscosity PEEK materials are prone to clogging. The driving mechanism transmits power through the engagement of the limit groove and the limit bar, and automatically triggers the heating power to increase when the resistance increases, ensuring the fluidity of the melt; the electromagnetic heating mechanism uses the relative movement of the permanent magnet and the coil to generate eddy current heating, which significantly improves the heating effect during high-speed extrusion; the homogenizing mechanism monitors the material compaction degree in real time through the pressure sensor, and intelligently adjusts the feed speed to avoid hollowing or overpressure blockage. The equipment is particularly suitable for the regeneration of recycled PEEK waste containing impurities, and has the advantages of high-efficiency anti-clogging, energy consumption optimization and intelligent control.

The other side of the extrusion cylinder 1 is connected to the discharge cylinder, and the extrusion nozzle 2 is slidably sleeved on the outside of the discharge cylinder.

[0050] In this embodiment, when in use, the driving motor 401 is started to drive the driving column 402 to rotate, and the driving column 402 drives the connecting cylinder 7 to rotate through the cooperation of the limiting groove and the limiting bar 701. The connecting cylinder 7 first drives the main shaft 6 to rotate synchronously through the cooperation of the spiral bar 702 and the spiral groove 1001. The main shaft 6 drives the extrusion auger 606 to rotate, and then the recycled engineering plastic is crushed and added to the feed nozzle 102, so that it enters the extrusion barrel 1, so that the rotating spiral auger 309 conveys the plastic. During the conveying process, the extrusion auger 606 is subjected to resistance, thereby limiting the rotation of the main shaft 6, so that the connecting cylinder 701 is rotated. The spiral groove 1001 in the connecting tube 10 drives the connecting tube 7 to move to the side close to the extrusion tube 1 by cooperating with the spiral strip 702, and drives the linkage plate 501 to move to the right by abutting with the abutting wheel 504, and compresses the reset spring 503. When the pressure on the reset spring 503 is balanced with the rotation resistance of the main shaft 6, the main shaft 6 continues to rotate to transport the plastic particles, heat the plastic particles through the first heating ring 103, and add the engineering plastic particles into the feed hopper 301 at the same time, then start the rotating motor 303 to drive the rotating shaft 308 to rotate, and the rotating shaft 308 drives the rotating frame 3 10. The scraper 311 and the spiral auger 309 rotate. The scraper 311 and the rotating frame 310 can stir the engineering plastic particles when they rotate. The spiral auger 309 applies a downward thrust to the engineering plastic when it rotates, so that it enters the extrusion barrel 1, so that the plastic particles are evenly distributed to avoid hollowing. When the spiral auger 309 is subjected to resistance from the plastic particles, it pushes the rotating shaft 308 to drive the connecting disk 305 and the lifting disk to move upward and squeeze the second pressure sensor 307, so that the compaction degree of the plastic can be judged by the second pressure sensor 307. When the pressure is greater than the preset value, the controller 4 04 controls the output shaft of the rotary motor 303 to decelerate rotation to avoid blockage, and when the pressure value monitored by the second pressure sensor 307 is less than the preset value, controls the output shaft of the rotary motor 303 to accelerate rotation, thereby accelerating the transportation of plastic particles, so that the plastic particles are evenly distributed in the extrusion barrel 1, and then the extrusion auger 606 transports the plastic particles horizontally, and further heats the plastic particles through the second heating ring 104. After heating, the molten plastic is extruded from the extrusion hole 101 and the extrusion nozzle 2, and the main shaft 6 drives the horizontal shaft 604 and the lever 605 to rotate, thereby improving the distribution uniformity of the molten plastic;

[0051] The temperature of the molten plastic is monitored by the temperature sensor 105, and the temperature of the first heating ring 103 and the second heating ring 104 is controlled by the controller 404 to adjust accordingly. When the rotational resistance of the extrusion auger 606 and the main shaft 6 increases, the distance the linkage plate 501 moves to the right increases, and drives the conductive tube 507 to move synchronously. When the rotational resistance is large enough, the two conductive tubes 507 are sleeved on the outside of the corresponding resistor bar 508, so that the circuit of the energy storage power supply 11 and the U-shaped electric heating rod 601 is connected. The current is introduced into the first arc-shaped conductive plate 509 through one of the conductive tubes 507 and the resistor bar 508. The first arc-shaped conductive plate 509 guides the current to the U-shaped electric heating rod 601 by abutting against the first conductive ring 602, and then returns to the U-shaped electric heating rod 601 through the second conductive ring 603, the second arc-shaped conductive plate 510 and another set of conductive tubes 507 and the resistor bar 508. The negative pole of the energy storage power supply 11 forms a loop, and when current flows through the U-shaped electric heating rod 601, heat is generated to heat the main shaft 6 and the spiral auger 309, thereby heating the plastic, preventing its temperature from being too low to affect its fluidity, and preventing cooling and condensation on the surface of the extrusion auger 606 from causing blockage. At the same time, as the resistance encountered by the extrusion auger 606 increases, the two conductive cylinders 507 move further to the right, and the length of the two resistor bars 508 connected to the circuit becomes shorter, so that the current flowing through the U-shaped electric heating rod 601 increases, and its heat generation increases, thereby improving the heating effect on the plastic and avoiding blockage. When the resistance encountered by the extrusion auger 606 is too large, the linkage plate 501 drives the pressing rod 505 to press the touch button 506, thereby controlling the drive motor 401 and the rotating motor 303 to stop running through the controller 404, thereby performing shutdown maintenance;

[0052] The extrusion speed is adjusted by adjusting the output shaft speed of the drive motor 401, and the main shaft 6 drives the mounting frame 801 to rotate synchronously, and drives the centrifugal plate 802 to perform circular motion. The centrifugal plate 802 is thrown outward under the action of centrifugal force and compresses the compression spring 804. When the rotation speed of the main shaft 6 is large enough, the connecting column 803 is driven to insert into the linkage groove, thereby driving the linkage ring 905 and the turntable 901 to rotate synchronously with the main shaft 6. When the turntable rotates, the multiple mounting seats 902 are driven to perform circular motion, thereby driving the coil and the electric heating plate 904 to perform circular motion, and the closed coil continuously cuts the magnetic flux lines generated by the permanent magnet 906, thereby generating an induced electromotive force, thereby generating an induced current in the electric heating plate 904, causing it to heat up, thereby heating the turntable 901, thereby improving the heating effect of the plastic during high-speed extrusion. The pressure on the extrusion nozzle 2 is monitored by the second pressure sensor 307. When the pressure received by the second pressure sensor 307 is too large, the speed of the drive motor 401 is controlled to decrease to avoid blockage.
