Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical addition equipment technology, and in particular to a modified pharmaceutical addition device for polymer materials. Background Technology

[0002] Polymer materials are usually composed of compounds with relatively high molecular weight. They have many advantages such as light weight, high strength, corrosion resistance, and good insulation. In the production and processing of polymer materials, it is often necessary to add modifying agents to further improve their performance. Currently, when adding modifiers to polymer materials, the modifiers are often added in large quantities at once. This inevitably leads to uneven distribution of the modifiers during mixing, requiring a significant amount of time for thorough mixing of the polymer materials and the modifiers, and affecting the mixing effect. At the same time, the modifiers are prone to clumping due to factors such as moisture and compression, and clumped modifiers are difficult to disperse quickly, reducing the actual mixing efficiency. Therefore, to solve these problems, designing a device for adding modifiers to polymer materials is something we need to consider. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polymer material modification agent addition device. Addressing usage issues, it incorporates an addition mechanism that controls a motor to rotate a circular plate. Combined with the lower and upper feed inlets, this enables periodic and uniform addition of the agent, improving subsequent mixing efficiency. Furthermore, it includes a pulverizing component to break down any agglomerates within the agent, ensuring efficient mixing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A device for adding a modifier to a polymer material includes a mixer with a feed pipe connected to its inner top; a dosing mechanism including a circular fixed plate fixedly connected to the lower end of the feed pipe, a motor mounted on the lower end of the circular fixed plate, a rotating shaft rotatably connected to the upper end of the circular fixed plate, the lower end of the rotating shaft passing through the circular fixed plate and fixedly connected to the output shaft of the motor, a circular rotating plate fixedly connected to the outer side of the rotating shaft, a conical rotating block fixedly connected to the upper end of the circular rotating plate, a lower feed port vertically opened at the upper end of the circular fixed plate, and an upper feed port opened at the upper end of the circular rotating plate; and a crushing assembly including a mesh plate fixedly connected to the inner wall of the feed pipe, with crushing rollers rotatably connected to both sides of the rotating shaft.

[0005] Preferably, the mesh plate and two rolling rollers are used together, and a baffle is fixedly connected to the inner wall of the feed pipe.

[0006] Preferably, the lower end of the baffle is attached to the upper end of the circular rotating plate, and the right side of the baffle is attached to the left side of the conical rotating block.

[0007] Preferably, the lower feed port and the upper feed port are staggered in the vertical direction.

[0008] Preferably, a protective cover is fixedly connected to the lower end of the circular fixing plate, and the motor is located inside the protective cover.

[0009] Preferably, the upper end of the feed pipe is rotatably provided with a top cover.

[0010] Compared with the prior art, the advantages of this utility model are as follows: A crushing component is installed, which drives two crushing rollers to rotate by starting the motor. Together with the screen plate, it can crush the modified agent in the feed pipe, effectively avoiding the impact of some clumps of the agent on the subsequent mixing efficiency with the polymer material. A dosing mechanism is also installed, which drives the circular rotating plate and the conical rotating block to rotate, so that the upper feed port and the lower feed port are periodically connected. This can achieve uniform addition of the modified agent in the feed pipe, effectively improving the mixing effect of the modified agent and the polymer material, greatly reducing the time required for uniform mixing, and the baffle can scrape the remaining agent in the feed pipe to ensure complete addition of the agent.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1-3A device for adding a modifier for polymer materials includes a mixer 1. The mixer 1 is mainly composed of a frame, a drive system, a stirrer, a discharge port, a control system, etc. It can efficiently mix polymer materials and modifiers. The top of the mixer 1 is connected to a feed pipe 2 for adding modifiers into the mixer 1. The upper end of the feed pipe 2 is rotatably equipped with a top cover 14. The system also includes a dosing mechanism, which comprises a circular fixed plate 3 fixedly connected to the lower end of the feed pipe 2. A motor 4 is mounted on the lower end of the circular fixed plate 3, and a protective cover 13 is fixedly connected to the lower end of the circular fixed plate 3. The motor 4 is located inside the protective cover 13. A rotating shaft 5 is rotatably connected to the upper end of the circular fixed plate 3. The lower end of the rotating shaft 5 passes through the circular fixed plate 3 and is fixedly connected to the output shaft of the motor 4. A circular rotating plate 6 is fixedly connected to the outer side of the rotating shaft 5. A conical rotating block 7 is fixedly connected to the upper end of the circular rotating plate 6. A lower feed port 8 is vertically opened at the upper end of the circular fixed plate 3, and an upper feed port 9 is opened at the upper end of the circular rotating plate 6. The lower feed port 8 and the upper feed port 9 are offset vertically. By controlling the motor 4 to drive the circular rotating plate 6 to rotate, the upper feed port 9 is periodically connected to the lower feed port 8. This allows the agent in the feed pipe 2 to be periodically and evenly added to the mixer 1, thereby improving the mixing effect of polymer materials and modified agents. A baffle 12 is fixedly connected to the inner wall of the feed pipe 2. The lower end of the baffle 12 is attached to the upper end of the circular rotating plate 6, and the right side of the baffle 12 is attached to the left side of the conical rotating block 7. The baffle 12 can scrape the modified agent on the upper end of the circular rotating plate 6 and the outer side of the conical rotating block 7 to ensure the complete addition of the modified agent in the feed pipe 2. The device also includes a crushing assembly, which consists of a screen plate 10 fixedly connected to the inner wall of the feed pipe 2, and two crushing rollers 11 rotatably connected to the left and right sides of the rotating shaft 5. The screen plate 10 and the two crushing rollers 11 cooperate, and the two crushing rollers 11 are driven to move in a circular motion by controlling the motor 4. This can crush the modified agent that is clumped on the screen plate 10 into powder, thereby avoiding the influence of some clumped modified agent on the mixing efficiency with the polymer material.

[0015] In this invention, during use, the polymer material is first put into the mixer 1 and the mixer 1 is started. Then, the top cover 14 is opened and powdered modifier is added into the feed pipe 2. During the addition process, most of the powdered modifier will pass directly through the screen plate 10 and fall onto the upper end of the circular rotating plate 6, while some of the clumped modifier will remain on the upper end of the screen plate 10. After the addition is completed, the top cover 14 is opened and the motor 4 is turned on, which drives the rotating shaft 5 to rotate and drives the two crushing rollers 11 to move in a circle to crush the clumped modifier on the screen plate 10 into powder. This can avoid the clumped modifier from affecting the mixing efficiency with the polymer material. During the rotation of the rotating shaft 5, it drives the circular rotating plate 6 and the conical rotating block 7 to rotate synchronously. During this period, whenever the upper feed port 9 on the circular rotating plate 6 connects with the lower feed port 8 on the circular fixed plate 3, the modified agent in the feed pipe 2 is evenly added to the mixer 1 through the upper feed port 9 and the lower feed port 8. In this way, by periodically adding the modified agent to the mixer 1, the mixing effect of the modified agent and the polymer material is ensured, and the time required for the modified agent and the polymer material to be completely mixed is greatly reduced.

[0016] It is worth mentioning that during the rotation of the circular rotating plate 6, the baffle 12 can scrape the modified agent on the upper end of the circular rotating plate 6 and the outer side of the conical rotating block 7, so as to ensure that the remaining modified agent in the feed pipe 2 can also be completely added to the mixer 1, ensuring the full use of the modified agent. After all the modified agent is added, the mixer 1 can ensure the full mixing of the polymer material and the modified agent, and finally complete the modification agent addition and mixing work of the polymer material. It should be noted that the wiring of motor 4 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control, power supply method and wiring layout of motor 4 will not be explained in detail.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
