Technical Field
[0001] This utility model relates to the field of mixing machine technology, specifically to a mixing machine for preparing antibacterial polypropylene masterbatch that allows for convenient control of feeding. Background Technology
[0002] In the preparation of antibacterial polypropylene masterbatch, in order to ensure that the antibacterial agent is evenly distributed in the plastic base material, a mixer is required to fully mix the raw materials. Although basic mixing can be achieved, it is difficult to accurately control the feeding ratio and mixing sequence of different components (such as polypropylene base material, antibacterial agent, compatibilizer, etc.). When processing high addition ratios or nano-sized antibacterial agents, local aggregation is prone to occur, resulting in a decrease in antibacterial performance. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a simple, rationally designed, and easy-to-use mixer for preparing antibacterial polypropylene masterbatch with convenient feeding control. This mixer uses multiple feeding hoppers to separate the raw materials and controls the flow of the raw materials by driving a movable plate.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a mixer body, a mixing motor is disposed in the upper middle part of the mixer body, and a mixing paddle is disposed after the output shaft of the mixing motor passes through the mixer body; it also includes:

[0006] The number of convex rings is the same as that of the feed bin, and they are fixedly arranged on the upper side of the mixer body with equal circumference and angles, and the feed bin passes through the convex rings;
[0007] The number of clips and rings is consistent with that of the feed hopper. They are respectively sleeved and fixed on the outer ring wall of the feed hopper, and the bottom of the clips and rings is provided with annular grooves. The clips and rings are clamped onto the convex rings through the annular grooves.
[0008] Movable plates, the number of which is the same as that of the guide frame, and which are positioned in contact with the lower side of the guide frame;
[0009] The number of opening and closing components is the same as that of the movable plate, and they are respectively disposed on the upper side of the movable plate;
[0010] The number of reinforcing rings is the same as that of the feed hopper, and they are fixedly installed on the inner top surface of the mixer body in a circumferentially angularly distributed manner, with the bottom end of the feed hopper passing through the reinforcing rings.
[0011] The reinforcing components are several in number, and are arranged in pairs on the left and right sides of the reinforcing ring;
[0012] Through the above technical solution design, the feed hopper is inserted into the body of the mixer and positioned and installed by the locking and cooperation of the clip and ring with the convex ring. Then, the feed hopper is reinforced by the reinforcement component. The raw material enters from the feed hopper and flows into the body of the mixer from the guide frame.

[0013] As a further improvement of this utility model, the opening and closing component includes:
[0014] The support shaft consists of two shafts, which are symmetrically fixed on the front and rear sides of the movable plate. The support shaft is located on the left side of the discharge end of the guide frame, and the outer end of the support shaft is screwed onto the inner ring wall of the feed hopper via a bearing.
[0015] Two connecting blocks are provided, located on the right side of the support shaft and fixedly mounted on the outer wall of the movable plate; a moving groove is provided inside the connecting block, and a through groove is provided on the outer side of the moving groove.

The support rod slides through the moving groove. A strip rod slides through the groove. The inner end of the strip rod is connected to the support rod.
[0018] The above technical solution design involves activating an electric push rod to drive the support rod, causing the movable plate to rotate downwards around the pivot center of the support shaft, opening the movable plate so that the raw material flows downwards along it. Conversely, activating the electric push rod in the opposite direction causes the movable plate to rotate upwards, closing it and sealing the bottom of the guide frame, thus limiting the flow of the raw material.

[0028] The above technical solution design reinforces the connection between the card and the ring and the convex ring.
[0029] The working principle of this utility model is as follows: The feed hopper is inserted into the body of the mixer and positioned by the locking and engagement of the clip and ring with the convex ring. The stability of the clip and ring is reinforced by the tightening engagement of the nut and stud. Then, the rotating motor is started to rotate the rotating component, which drives the drive rod to move the drive block, which in turn moves the insertion platform until it is inserted into the feed hopper. The raw material enters from the feed hopper and flows into the mixer body from the guide frame.
