By rotating the rotating sleeve 61, the rotating sleeve 61 can drive the gear ring 62 to rotate, which will not affect the extrusion tube 3. A rubber pad is connected to the outside of the rotating sleeve 61. The rubber pad is convenient for manual rotation of the rotating sleeve 61. The rotating sleeve 61 is a circular structure with a smooth surface. It is inconvenient to directly rotate the rotating sleeve 61. Through the setting of the rubber pad, the resistance of the finger to the outside of the rotating sleeve 61 is increased, which is convenient for rotating the rotating sleeve 61 more labor-saving and faster. One end of the rotating sleeve 61 is connected to the gear ring 62, and the rotating sleeve 61 and the gear ring 62 can drive multiple shafts 68 to rotate.

[0021] Reference Figure 3-5The filter screen 5 is connected to the outside with a connecting plate 63. When the connecting plate 63 is fixed inside the fixing groove 66, the filter screen 5 and the extrusion tube 3 are fixedly connected. When the connecting plate 63 is not fixed, the filter screen 5 can be disassembled. A plug-in groove 64 is provided at one end of the connecting plate 63. The extrusion tube 3 is connected to the outside with a support frame 65. A fixing groove 66 is provided at one end of the support frame 65. One end of the connecting plate 63 is located inside the fixing groove 66. A mounting plate 67 is connected to the inside of the support frame 65. The mounting plate 67 is rotatably connected to the rotating shaft 68. The plate supports the rotating shaft 68 and the round rod 612. A rotating shaft 68 is passed through one end of the mounting plate 67. The lower end of the rotating shaft 68 is rotatably connected to one side of the extrusion tube 3. One side of the lower part of the rotating shaft 68 A gear 69 is sleeved, one side of the gear 69 is meshed with the gear ring 62, the gear 69 and the gear ring 62 have a transmission function, the gear ring 62 rotates, so that the rotating shaft 68 rotates, the upper end of the rotating shaft 68 is connected with a circular seat 610, and both sides of the outer side of the circular seat 610 are connected with arc-shaped slide plates 611, and the arc-shaped slide plates 611 are arranged in an arc-shaped structure. When the rotating shaft 68 drives the arc-shaped slide plate 611 to rotate, the arc-shaped slide plate 611 presses the slide bar 616 to move downward, and the movement of the slide bar 616 drives the fixed sleeve 615 and the fixed column 617 to move, and both sides of the upper end of the mounting plate 67 are connected with round rods 612, the upper end of the round rods 612 is connected to the top of the inner wall of the support frame 65, and the outer side of the round rods 612 is sleeved with a moving frame 613;

[0022] The outer sleeve of the round rod 612 is provided with a spring 614, and the movable frame 613 moves downward to squeeze the spring 614. At this time, the spring 614 is in the process of accumulating force, so that the spring 614 is in a compressed state. When the arc-shaped slide plate 611 is separated from the slide bar 616, the spring 614 drives the sleeve 615 to return to the original position under the elastic potential energy of the spring 614. At this time, the arc-shaped slide plate 611 is still separated from the slide bar 616. One end of the spring 614 is connected to one side of the mounting plate 67, and the other end of the spring 614 is connected to one side of the movable frame 613. One end of the movable frame 613 is connected to the sleeve 615, and the sleeve 615 and the fixed column 617 are hollow structures. When the circular seat 610 rotates, the sleeve 615 and the fixed column 617 are driven to move downward. Since the sleeve 615 and the fixed column 617 are hollow structures, the circular seat 610 will not conflict with the fixed column 617, and thus will not affect the upward or downward movement of the fixed column 617. Slide rods 616 are connected to both sides of the sleeve 615. The outside of the slide rod 616 is in contact with the arc-shaped slide plate 611. The upper end of the sleeve 615 is connected to the fixed column 617.

The fixed column 617 passes through the plug-in slot 64 and extends to the outside of the support frame 65.

[0023] The implementation principle of a plastic foam granulator according to an embodiment of the present application is as follows: when in use, in the initial state, the connecting plate 63 is located inside the fixing groove 66, the fixing column 617 is plugged into the plug-in groove 64, the filter screen 5 is fixedly connected to the extrusion tube 3, and when the filter screen 5 needs to be replaced, the rotating sleeve 61 is rotated, the rotating sleeve 61 drives the gear ring 62 to rotate, the gear ring 62 drives multiple gears 69 to rotate, the gear 69 drives the rotating shaft 68 to rotate, the rotating shaft 68 drives the circular seat 610 to rotate, and the circular seat 610 drives the arc The arc-shaped slide plate 611 rotates, and the arc-shaped slide plate 611 contacts the slide bar 616. The arc-shaped slide plate 611 presses the slide bar 616 to move under the rotation of the arc-shaped slide plate 611, and the slide bar 616 drives the sleeve 615 to move. Under the sliding limit of the round rod 612, the sleeve 615 drives the fixed column 617 to move downward along a straight line, and the fixed column 617 moves to the outside of the plug-in slot 64, so that the connecting plate 63 is in an active state, and the filter screen 5 is moved to one side, so that the filter screen 5 can be removed, which is convenient for replacing and cleaning the filter screen 5.
