Detailed Implementation

[0013] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] See as Figure 1 —— Figure 3 As shown, this specific embodiment adopts the following technical solution: it includes a confluence core 1, a mold body 2, a perforated plate 3, a mold surface 4, a flow divider cone 5, a cover 6, a cutting assembly 7, a universal coupling 8, a quick-opening hub 9, a moving linear guide rail 10, a motor 12, and a guide rod 13; the confluence core 1 and the mold body 2 are connected by the quick-opening hub 9, and the quick-opening hub 9 is fixed on the extruder frame by a hinge fixing seat 11, forming an integrated structure, reducing the weight of the die head, and facilitating use and maintenance.

[0015] A perforated plate 3 is fixed between the confluence core 1 and the mold body 2. Opening the quick-opening HALF 9 allows the confluence core 1 to be separated from the mold body 2, enabling cleaning and replacement of the perforated plate 3. The quick-opening HALF 9 allows for rapid opening and closing. The mold body 2 is fixed to the mold surface 4. The feed inlet 14 of the confluence core 1 is figure-eight shaped. Material flows through the confluence core 1, merging two groups of material into one. After merging, the material is compressed into a dense molten material. The material of the confluence core 1 is 40Cr. Due to the PVC belt... It is corrosive. The flow channel is plated with hard chrome (t=0.04-0.06mm) and polished to a surface roughness of Ra=0.1 mirror finish. A flow divider cone 5 is fixed on the inner surface of the mold surface 4. The flow divider cone 5 and the mold body 2 form a flow channel 15. The function of the flow divider cone 5 is to guide the material evenly in the circumferential direction and evenly enter the mold surface 4. The back pressure can be controlled through the flow channel 15 to further improve the plasticizing performance of the material. The mold surface 4 is provided with a small discharge hole 16 for discharge and shaping.

[0016] The cutting assembly 7 includes a blade 71, a blade 72, a handle 73, a spring 74, and a nut 75. One end of the handle 73 is fitted with the blade 71, and the end of the blade 71 is fitted with the blade 72. The spring 74 is fitted onto the handle 73, and the end of the spring 74 is fixed by the nut 75. The other end of the handle 73 is connected to a motor 12 via a universal coupling 8. The motor 12 drives the handle 73 to rotate, causing the blade 71 at the end of the handle 73 to move around the axis of the handle 73. This allows the blade 72 at the end of the blade 71 to move in a circular motion on the surface of the discharge hole 16, achieving the pelletizing function. The spring 74 is used to manually control the fit between the blade 72 and the die surface 4. This ensures the pelletizing effect without causing the blade 72 to fit too tightly against the die surface 4, thus preventing excessive wear and extending the service life of the blade 72.

[0017] The motor 12 is fixed on the motor bracket 17, which is connected to the linear guide rail 10 via the guide rod 13. A cover 6 is provided on the outer periphery of the mold surface 4, and the cover 6 is fixed to the motor bracket 17. By disconnecting the universal coupling 8, the cover 6, the motor 12, the motor bracket 17, and the guide rod 13 can be moved backward along the linear guide rail 10 to clean the residual material on the mold surface 4, making it convenient for use and maintenance.

[0018] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
