[0043] Example 2

[0044] like Figures 5-6As shown, this utility model proposes a polyether ether ketone pulverizing device. Compared with Embodiment 1, this embodiment details the structure of the capacity adjustment mechanism.

[0045] The capacity adjustment mechanism includes a fixed rod 701, a sliding disk 702, a sliding groove 703, and positioning holes 704. The fixed rod 701 is located on the side of the rotating disk 612 away from the quantitative conveying mechanism. The top of the fixed rod 701 has a scale. The sliding disk 702 is slidably disposed on the outside of the fixed rod 701. The sliding groove 703 is disposed on the rotating disk 612. The positioning holes 704 are located on the side of the fixed rod 701. The number of positioning holes 704 is the same as the number of scales, and one scale corresponds to one... A positioning hole 704 is provided. A fixing bracket 707 is provided on the outer side of the sliding disk 702. An insert rod 705 is slidably disposed on the inner side of the fixing bracket 707. A spring 706 is provided on the outer side of the insert rod 705. The end of the insert rod 705 is engaged with the positioning hole 704, thereby fixing the position of the sliding disk 702. A pull rod 713 is provided at the end of the insert rod 705. A rotating rod 708 is rotatably disposed on the side of the sliding disk 702 near the rotating disk 612. The rotating rod 708 is away from the sliding disk 702. A fixing member 709 is rotatably mounted at one end, and a sliding block 710 is mounted on the side of the fixing member 709. The side of the sliding block 710 is connected to the outer side of the metering disk 711. A baffle 712 is mounted on the top of the metering disk 711. The baffle 712 is slightly longer than the sliding groove. Pulling up the pull rod 713 causes the insertion rod 705 to disengage from the positioning hole 704. At this time, the sliding disk 702 can slide. Since there are four rotating rods 708, the sliding disk 702 can be moved simultaneously by the four rotating rods 708. The four sliding blocks 710 slide, which in turn drive the metering discs 711 to slide, causing the four metering discs 711 to extend outward or retract inward simultaneously, thereby changing the capacity of the metering slots in the rotating disc 612. Once the scale on the fixing rod 701 is aligned, the sliding disc 702 is moved to the corresponding scale and then stopped. Then the pull rod 713 is released, and the insertion rod 705 is re-engaged into the positioning hole 704 under the action of the spring 706, thereby fixing the position of the sliding disc 702.

[0046] In summary, when using this utility model, pulling up the lever 713 causes the insertion rod 705 to disengage from the positioning hole 704. The moving sliding disk 702 drives the four sliding blocks 710 to slide through the four rotating rods 708 respectively. The sliding blocks 710 drive the metering disk 711 to slide, thereby causing the four metering disks 711 to simultaneously extend outward or retract inward, thus changing the capacity of the measuring groove in the rotating disk 612. After aligning the scale on the fixed rod 701 with the sliding disk 702, stop when it moves to the corresponding scale, and then release the lever. 713. Under the action of spring 706, the insertion rod 705 is re-engaged into the positioning hole 704, thereby fixing the position of the sliding disk 702. After the amount of material to be added to the capacity tank is determined, polyetheretherketone is poured into the feeding port 4. The material enters the capacity tank of the rotating disk 612 through the feeding pipe 603. At the same time, motor 1 501 and motor 2 605 are started. Motor 2 605 drives the rotating shaft 3 611 to rotate, which in turn drives the rotating gear 2 615 to rotate. The rotation of rotating gear 2 615 drives the rotating gear 1 610 to rotate. The first spur gear 610 drives the second rotating shaft 609 to rotate the power rod 617. The power rod 617 drives the rotating block 616 to rotate. When the rotating block 616 rotates onto the intermittent rotating ring, it can cut into the slide rail, thereby driving the intermittent rotating ring to rotate. The intermittent rotating ring drives the rotating disk 612 to rotate, thereby transporting the polyetheretherketone (PEEK) inside the rotating disk 612. When the rotating block 616 disengages from the intermittent rotating ring and rotates outside the intermittent rotating ring, it can no longer drive the intermittent rotating ring to rotate, and the rotating disk 612 stops transporting. The capacity tank at the bottom can feed the polyether ether ketone stored inside into the crushing box 1 through the feed pipe 604. At this time, the motor 501 drives the crushing roller 507 to rotate through the rotating shaft 503. At the same time, the rotating shaft 503 drives the drive wheel 504 to rotate. The drive wheel 504 drives the driven wheel 505 to rotate through the transmission belt 506. The driven wheel 505 drives the crushing roller 507 to rotate through the rotating shaft 503 on it. The two crushing rollers 507 rotate at the same time, thereby crushing the fed polyether ether ketone.
