Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: an extrusion granulation device for PVB resin production, including a control base box 1, an extrusion module 3 connected to the top of the control base box 1, an extrusion cylinder 4 provided on one side of the extrusion module 3, a feeding box 2 connected to the top of the extrusion module 3, a cutting module 10 connected to the outer wall of the extrusion cylinder 4, an extrusion plate 7 provided on one side of the inner wall of the extrusion cylinder 4, and an adjusting device 8 connected to one side of the extrusion plate 7. The adjusting device 8 includes an adjusting groove 815 and two fixing plates 807, and the inner wall of the adjusting groove 815 slides... An adjusting plate 801 is dynamically connected, and a connecting plate 812 is connected to one side of the adjusting plate 801. A movable groove 814 is formed inside the connecting plate 812. Both sides of the inner wall of the movable groove 814 have stroke grooves 813. A threaded seat 809 is slidably connected inside the movable groove 814. A threaded rod 808 is threadedly connected inside the threaded seat 809. One end of the threaded rod 808 is connected to a knob 811. Both sides of the threaded seat 809 are connected to stroke blocks 810. A second connecting groove 804 is formed on the inner wall of the adjusting groove 815. Adjustment... The groove 815 is formed inside the extrusion plate 7, and one side of the connecting plate 812 extends out of the adjusting groove 815 through the second connecting groove 804. Both sides of the connecting plate 812 are slidably connected to the inner wall of the second connecting groove 804, and the outer wall of the stroke block 810 is slidably connected to the stroke groove 813. A first connecting groove 5 is formed on one side of the inner wall of the extrusion cylinder 4. One end of the connecting plate 812 extends out of the extrusion cylinder 4 through the first connecting groove 5, and one side of the fixing plate 807 is connected to the outer wall of the extrusion cylinder 4. One end of the threaded rod 808 is connected to the fixing plate. One side of the 807 is rotatably connected, and another fixed plate 807 is embedded with a bearing, which is rotatably connected to the outer wall of the knob 811. A rotating groove 806 is opened on one side of the inner wall of the adjusting groove 815, and a rotating ring 803 is slidably connected in the rotating groove 806. One side of the rotating ring 803 is connected to one side of the adjusting plate 801. Multiple sliding grooves 805 are opened on the inner wall of the adjusting groove 815, and a sliding block 802 is slidably connected in the sliding groove 805. One side of the sliding block 802 is connected to the outer wall of the adjusting plate 801.

[0029] In a specific implementation, by setting an adjustment device 8, the knob 811 is rotated, and a turning block on one side is provided. The outer wall of the turning block has an anti-slip groove to prevent slippage during turning, thus preventing operation. The turning block drives the knob 811 to rotate, which in turn drives the threaded rod 808 to rotate. The threaded rod 808 drives the threaded seat 809 to move. Then, the stroke block 810 slides within the stroke groove 813, causing the threaded seat 809 to drive the connecting plate 812 to move to one side. This causes the connecting plate 812 to drive the adjustment plate 801 to rotate. A sliding block 802 slides and is limited within the sliding groove 805, ensuring that the adjustment plate 801 rotates during use. With good support, the adjustment plate 801 is prevented from shifting and affecting its use. The rotation of the adjustment plate 801 causes the granulation holes between the adjustment plate 801 and the extrusion plate 7 to be misaligned, thereby adjusting the granulation size to meet different application scenarios. By setting a rotating ring 803 to rotate within the rotating groove 806 and sealing it, the rotating ring 803 seals the gap between the adjustment plate 801 and the extrusion plate 7, thus avoiding waste of raw materials during granulation. The extrusion module 3 is equipped with a drive unit and an extrusion auger. The drive unit drives the extrusion auger to rotate, so that the extrusion auger extrudes the molten raw materials. This technology is existing technology and does not need to be described in detail.

[0030] A base plate 6 is connected to one side of the control base box 1, and a cleaning device 9 is connected to the top of the base plate 6. The cleaning device 9 includes a support frame 902, the bottom of which is connected to the top of the base plate 6. Both sides of the inner wall of the support frame 902 are provided with built-in grooves 903. A cleaning plate 901 is slidably connected in the built-in grooves 903. Multiple excess grooves 905 are provided on one side of the cleaning plate 901. A spring 907 is connected to one side of the excess groove 905. The other end of the spring 907 is connected to one side of the inner wall of the built-in groove 903. A guide slope is provided on one side of the cleaning plate 901. A fixing groove 906 is provided on one side of the excess groove 905. A fixing rod 904 is slidably connected in the fixing groove 906. The other end of the fixing rod 904 is connected to one side of the inner wall of the built-in groove 903. The spring 907 is sleeved on the outside of the fixing rod 904.

[0031] In a specific implementation, by setting up a cleaning device 9, when the cutting blade of the cutting module 10 rotates, one side of the cutting blade contacts the cleaning plate 901, and through compression, the two cleaning plates 901 move to both sides respectively. During the movement of the cleaning plates 901, the spring 907 is compressed, causing the spring 907 to generate a rebound force. Subsequently, as the cutting blade continues to move, the spring 907, through its rebound, drives the cleaning plate 901 to compress the cutting blade, thereby scraping and cleaning the surface of the cutting blade. This prevents particles from adhering to the surface of the cutting blade during the cutting and granulation process, thus avoiding affecting the cutting effect of the next cut. By setting up a fixing rod 904 to support the spring 907, the spring 907 is prevented from bending during compression, thus avoiding affecting the rebound effect of the spring 907.

[0032] Working principle: During use, the raw material is poured from the feeding box 2 into the extrusion cylinder 4. Then, the drive unit in the extrusion module 3 drives the extrusion auger to rotate, so that the extrusion auger conveys the raw material and granulates it through the extrusion plate 7. When different particle sizes are required, the knob 811 is turned, so that the knob 811 drives the threaded rod 808 to rotate. The threaded rod 808 drives the threaded seat 809 to move, so that the threaded seat 809 drives the stroke block 810 to slide in the stroke groove 813. This causes the stroke block 810 to drive the connecting plate 812 to move to one side, which in turn causes the connecting plate 812 to drive the adjusting plate 801 to rotate, so that the granulation holes between the adjusting plate 801 and the extrusion plate 7 are misaligned, thereby meeting the granulation requirements of different sizes. Then, the cutting blade in the cutting module 10 rotates, so that the cutting blade cuts the particles. Then, the cutting blade continues to rotate, so that one side of the cutting blade squeezes the cleaning plate 901, so that the cleaning plate 901 scrapes the particles on the surface of the cutting blade, preventing the particles from adhering to the surface of the cutting blade and affecting the cutting.
