[0030] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In this application, the directions or positional relationships indicated by the terms "upper", "inner", "outer", "middle", etc. are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0032] like Figure 1-4 As shown, a high-speed kneading machine for producing polyphenylene sulfide composite materials comprises a heating cylinder 1, the upper end of the heating cylinder 1 is connected to a first driving motor 2, a rotating rod 3 is rotatably connected inside the heating cylinder 1, the first driving motor 2 drives the rotating rod 3 to rotate, a heating wire 4 is arranged inside the rotating rod 3, a stirring blade 5 is connected along the circumference of the rotating rod 3, and the stirring blade 5 is spirally arranged along the longitudinal direction of the rotating rod 3, a feed port 6 is connected to the upper end of the side wall of the heating cylinder 1, and a discharge port 7 is connected to the lower end of the side wall of the heating cylinder 1. An appropriate amount of composite material raw material is added to the heating cylinder 1 through the feed port 6, and then the heating wire 4 in the heating cylinder 1 is adjusted to a suitable temperature, and the heating cylinder 1 is preheated to promote the softening and mixing of the composite material raw material. Then the first driving motor 2 is started to drive the rotating rod 3 and the stirring blade 5 to start rotating, and the stirring blade 5 is spirally arranged along the longitudinal direction of the rotating rod 3, and then shearing and mixing are achieved in the stirring process of the composite material raw material, thereby improving the softening speed and mixing efficiency of the raw material and ensuring the uniformity of the composite material.

[0033] The top side wall of the heating cylinder 1 is connected with a vacuum port 8, and the lower end of the heating cylinder 1 is detachably connected with a waste barrel 9, and a support rod 10 is connected inside the waste barrel 9. The top of the support rod 10 is connected with a material receiving plate 11 corresponding to the heating cylinder 1, and the material receiving plate 11 is arranged to be tilted downward, and a sealing strip 12 is connected to the surrounding side of the material receiving plate 11, which ensures the airtightness of the composite material during the defoaming and feeding process. The support rod 10 and the rotating rod 3 are clamped together by a clamping block 13, so that it is convenient to disassemble the heating cylinder 1 and the internal structure, and it is convenient to replace and clean, thereby improving the flexibility of the equipment. The bottom of the support rod 10 is connected with a vibration motor 14, and after the mixing is completed, the heating cylinder 1 can be vacuumed through the vacuum port 8 to ensure that there are no bubbles in the composite material. During the defoaming process, the vibration motor 14 is used for vibration treatment, thereby helping the bubbles to be quickly released from the composite material, thereby effectively removing the bubbles in the composite material, ensuring the bubble-free property of the final product, and improving the product quality. After the raw materials are fully kneaded and mixed in the heating cylinder 1, the discharge port 7 is opened to discharge the mixed polyphenylene sulfide composite material for subsequent treatment. The bottom of the vibration motor 14 is connected to the first cylinder 15 through a rotating block, and the first cylinder 15 is connected to the side wall of the heating cylinder 1. A plurality of drop grooves 16 are evenly opened on the circumference of the waste barrel 9, and a drop hole 17 is opened at the bottom of the waste barrel 9.

The diameter of the stirring blade 5 increases from top to bottom along the direction of the rotating rod 3, so as to facilitate the vacuum defoaming treatment of the composite material and ensure that there are no bubbles in the composite material.

[0035] The working process of the utility model is:

[0036] First, add an appropriate amount of polyphenylene sulfide and its composite material raw materials into the heating cylinder 1 through the feed port 6, and then adjust the heating wire 4 in the heating cylinder 1 to a suitable temperature, preheat the heating cylinder 1, and then promote the softening and mixing of polyphenylene sulfide and its composite material raw materials. Then start the first drive motor 2 to drive the rotating rod 3 and the stirring blade 5 to start rotating. The stirring blade 5 is spirally arranged along the longitudinal direction of the rotating rod 3, and then shearing and mixing are achieved during the stirring process of the raw materials. After the mixing is completed, the heating cylinder 1 can be vacuumed through the vacuum port 8 to ensure that there are no bubbles in the composite material. During the degassing process, the vibration motor 14 is used for vibration treatment to help the bubbles to be quickly released from the composite material. When the raw materials are fully kneaded and mixed in the heating cylinder 1, the discharge port 7 is opened to discharge the mixed polyphenylene sulfide composite material for subsequent treatment. After the discharge of the polyphenylene sulfide composite material is completed, the first drive motor 2 drives the rotating rod 3 and the stirring blade 5 to start rotating, and the vibration motor 14 performs vibration treatment. The remaining composite material in the heating cylinder 1 falls into the receiving plate 11 along with the stirring blade 5 set to be tilted downward, and then the first cylinder 15 drives the motor and the support rod 10 to move downward, and then the support rod 10 drives the receiving material to move downward, and then the remaining composite material slides into the dropping hole 17 through the multiple dropping grooves 16 opened on the side of the waste barrel 9, and then is smoothly discharged through the dropping hole 17.
