This not only affects the quality of subsequent processing of plastic materials but also consumes more processing time and costs. To better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new structural composition that differs from the existing technology.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-3 A pretreatment device for composite plastic materials includes a support frame 2. A housing 1 is fixed to the top of the support frame 2 by bolts. A crushing component 9 is provided inside the housing 1. The crushing component 9 includes two crushing rollers and a motor. The motor drives the crushing rollers to rotate and crush the composite plastic material. A discharge pipe 3 is fixed to the bottom of the housing 1. A sliding ring 11 is slidably connected inside the discharge pipe 3. A strainer 10 is fixed inside the sliding ring 11. The crushed material enters the discharge pipe 3. The strainer 10 filters the material after the initial crushing, so that some of the material moves downward through the strainer 10, while the larger part of the material remains on the upper surface of the strainer 10.

[0024] Multiple tension springs 13 are welded to the bottom of the sliding ring 11. Multiple support plates 12 are fixed to the inner circumference of the discharge pipe 3 by bolts, and the tension springs 13 are fixed to the support plates 12 at the corresponding positions. Multiple guide rods 14 are fixed to the bottom of the sliding ring 11 by bolts, and the guide rods 14 are slidably connected to the support plates 12 at the corresponding positions at their bottom. The guide rods 14 can guide the sliding ring 11 so that it can move up and down stably. The tension springs 13 are sleeved on the outside of the guide rods 14. A connecting shaft 16 is rotatably connected to one side of the discharge pipe 3. One end of the connecting shaft 16 extends into the discharge pipe 3 and is welded with a top rod 15, and the top rod 15 is in contact with the sliding ring 11. A power assembly is provided on one side of the discharge pipe 3 to drive the connecting shaft 16 and the spiral blade 20 to rotate.

[0025] A second connecting pipe 7 is fixedly connected to one side of the housing 1. Two fixing blocks 6 are fixed to the outer wall of one side of the housing 1 by bolts. A guide pipe 5 is fixed to the two fixing blocks 6 by bolts, and the top end of the guide pipe 5 is connected to the second connecting pipe 7. A first connecting pipe 4 is fixedly connected between the guide pipe 5 and the discharge pipe 3. The power component connecting shaft 16 drives the push rod 15 to rotate. With the cooperation of the tension spring 13, the push rod 15 pushes the sliding ring 11 to move up and down, so that the material on the sieve plate 10 enters the first connecting pipe 4 along its slope and then falls into the guide pipe 5, which is conducive to the discharge of the material. The guide pipe 5 is equipped with a feeding component, which includes a rotating shaft. The rotating shaft is rotatably connected to the top inner wall of the guide pipe 5. A spiral blade 20 is fixed to the outside of the rotating shaft by bolts. The rotation of the rotating shaft causes the spiral blade 20 to convey the material entering the guide pipe 5 upward and re-enter the housing 1 through the second connecting pipe 7. The above operation is repeated to realize the recycling and crushing of the material and improve the crushing effect.

[0026] It should be noted that the power assembly includes a fixed frame 17, which is fixed to the outer wall of the discharge pipe 3 by bolts. A motor is fixed to the outer wall of the fixed frame 17 by bolts, and one end of the motor output shaft passes through the fixed frame 17 and is fixed to the connecting shaft 16. One end of the connecting shaft 16 is keyed to a first bevel gear 18, and the bottom end of the rotating shaft passes through the guide pipe 5 and is keyed to a second bevel gear 19. The first bevel gear 18 meshes with the second bevel gear 19. When the motor rotates, the connecting shaft 16 drives the first bevel gear 18 to rotate, thereby causing the second bevel gear 19 to drive the rotating shaft to rotate.

[0027] In particular, two inclined guide plates 8 are fixed to the inner walls of both sides of the housing 1 by bolts. There is a gap between the two guide plates 8 for feeding. The guide plates 8 can guide the composite plastic material and make it concentrate into the crushing component 9. The crushing component 9 is located at the bottom of the guide plates 8, and the gap between the two crushing rollers on the crushing component 9 corresponds vertically to the gap between the two guide plates 8. The sliding ring 11 is inclined and located on the side of the first connecting pipe 4.

[0028] Working principle: When it is necessary to crush composite plastic materials, the composite plastic materials to be processed first enter from the opening at the top of the shell 1, and are guided by the guide plate 8 to fall into the crushing component 9 for crushing. The crushed material enters the discharge pipe 3. The sieve plate 10 filters the material after the initial crushing, so that some of the material moves downward through the sieve plate 10, while the larger part of the material remains on the upper surface of the sieve plate 10. Then the motor is started. The motor rotates and the connecting shaft 16 drives the top rod 15 to rotate. With the cooperation of the tension spring 13, the top rod 15 pushes the sliding ring 11 to move up and down, so that the material on the sieve plate 10 enters the first connecting pipe 4 along its slope, and then falls into the guide pipe 5, which is conducive to the discharge of the material. At the same time, the rotation of the connecting shaft 16 drives the first bevel gear 18 to drive the second bevel gear 19 to rotate, so that the rotating shaft drives the spiral blade 20 to rotate, which conveys the material entering the guide pipe 5 upward and re-enters the shell 1 through the second connecting pipe 7. The above operation is repeated to realize the recycling crushing treatment of the material and improve the crushing effect.
