[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] Specific embodiments, such as Figure 1-5 The plastic waste recycling and crushing equipment shown includes: a mounting frame 1; a first crushing mechanism 2 for crushing plastic; a second crushing mechanism 3 mounted on the mounting frame 1 for crushing plastic; a conveying mechanism 4 connected to both the first crushing mechanism 2 and the second crushing mechanism 3 for conveying the plastic crushed by the first crushing mechanism 2 to the second crushing mechanism 3 for further crushing; a first recycling hole 5 located below the second crushing mechanism 3 for recycling the plastic crushed by the second crushing mechanism 3; and a second recycling hole 6 located at the end of the second crushing mechanism 3 away from the conveying mechanism 4 for recycling plastic that has not been crushed by the second crushing mechanism 3. In use, plastic waste is placed into the first crushing mechanism for primary crushing. The plastic after primary crushing is conveyed to the second crushing mechanism for secondary crushing via the conveying mechanism. The plastic after secondary crushing is screened out and collected through the first recycling hole, while the plastic that has not been secondary crushed is collected through the second recycling hole and returned to the first crushing mechanism for further crushing, ensuring thorough crushing of the plastic and guaranteeing the quality of subsequent product processing.

[0047] Specifically, the first crushing mechanism 2 includes: a first crushing mounting shell 21, which has a crushing inlet 211 and a crushing outlet 212; a first rotating shaft 22, which is rotatably mounted on the first crushing mounting shell 21 and located between the crushing inlet 211 and the crushing outlet 212; a second rotating shaft 23, which is rotatably mounted on the first crushing mounting shell 21 and correspondingly arranged with respect to the first rotating shaft 22; crushing blades 24, which are staggered and arranged on the first rotating shaft 22 and the second rotating shaft 23; a first rotating shaft drive member 25, which is mounted on the first crushing mounting shell 21 and is used to drive the first rotating shaft 22 to rotate; and a second rotating drive member 26, which is mounted on the first crushing mounting shell 21 and is used to drive the second rotating shaft 23 to rotate. Specifically, the first rotating shaft drive member 25 and the second rotating drive member 26 are motors, which electronically drive the first rotating shaft 22 and the second rotating shaft 23 to rotate, and the crushing blades 24 on the two rotating shafts cooperate to crush the plastic.

[0048] Additionally, the second crushing mechanism 3 includes: a second crushing mounting shell 31, which is mounted on the mounting frame 1 and has one end connected to the discharge port of the guiding mechanism 4; the first recovery hole 5 is located below the second crushing mounting shell 31; and the second recovery hole 6 is located at the end of the second crushing mounting shell 31 away from the guiding mechanism 4; a cylinder 32, which is horizontally disposed inside the second crushing mounting shell 31 and has one end connected to the discharge port of the guiding mechanism 4; and a plurality of through holes 321 are evenly spaced on the circumferential surface of the cylinder 32; a third rotating shaft 33, which is rotatably disposed inside the cylinder 32 along the axial direction of the cylinder 32; a crushing kit 34, which is sleeved on the third rotating shaft 33; a crushing support rod 35, which is disposed on the circumferential surface of the crushing kit 34; a crushing block 36, which is disposed at the end of the crushing support rod 35 away from the crushing support rod 35; and a third rotation drive 37, which is used to drive the third rotating shaft 33 to rotate. The third rotation drive 37 is a motor. The motor drives the third rotating shaft 33 to rotate, which in turn drives the crushing support rod 35 and the crushing block 36 to rotate. The crushing block 36 cooperates with the cylinder 32 to crush the plastic. The crushed plastic falls into the first recycling hole 5 through the equally spaced through holes 321 on the circumference of the cylinder 32 for collection, while the uncrushed plastic comes out directly from the second recycling hole 6 through the cylinder for recycling.

[0049] Furthermore, there are multiple crushing support rods 35, which are arranged axially along the third rotating shaft 33. This improves structural strength.

[0050] More specifically, the second crushing mounting shell 31 is provided with a crushing chamber 7 communicating with the first recycling hole 5 and a recycling chamber 8 communicating with the second recycling hole 6, and the cylinder 32 is disposed in the crushing chamber 7.

[0051] Furthermore, the guiding mechanism 4 includes: a guiding housing 41, which has a first channel 9 communicating with the crushing outlet 212 and a second channel 10 communicating with the cylinder 32, wherein the third rotating shaft 33 is rotatably inserted through the second channel 10; a guiding kit 42, which is sleeved on the third rotating shaft 33; and a spiral guiding protrusion 43, which is provided on the circumferential surface of the guiding kit 42. The third rotating shaft 33 can drive the guiding kit 42 and the spiral guiding protrusion 43 to rotate, so as to guide the plastic into the cylinder 32. This ensures that the plastic is smoothly conveyed to the second crushing mechanism 3.

[0052] Furthermore, the first crushing housing 21 is equipped with a conical guide hopper 11 on its crushing inlet 211, making it more convenient to use.

[0053] Specifically, a door 12 is hinged on the second crushing mounting shell 31.
