[0015] The beneficial effects of this application are: This application discloses a semi-solid quantitative slurry preparation mechanism for magnesium alloys. The quantitative conveying mechanism utilizes a conveying chamber and a quantitative chamber within a conveying pipeline. A conveying structure rotates within the conveying chamber to melt the material and transport it towards the quantitative chamber. Simultaneously, a closing structure moves towards the quantitative chamber to seal it. A push-pull structure, as the material is continuously transported towards the quantitative chamber, pulls the conveying screw away from the quantitative chamber.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0018] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.
[0020] Reference Figure 1 , Figure 2 as well as Figure 3 This application provides a magnesium alloy semi-solid quantitative slurry preparation mechanism, including a pipeline structure 1, a conveying structure 2, a closed structure 3, and a push-pull structure 4 disposed on the pipeline structure 1. The pipeline structure 1 is used to support and install the various structures and to guide the material transport. The pipeline structure 1 includes a conveying pipeline 11, which is an integrally formed structure. The conveying pipeline 11 has a conveying chamber 111 and a quantitative chamber 112. The conveying chamber 111 has an inlet end and an outlet end. The quantitative chamber 112 is located at the outlet end. A plurality of heating elements 12 for heating the conveying chamber 111 are arranged along its length direction. The heating elements 12 can be electric heating wires. The heating elements 12 are arranged along the length direction of the conveying pipeline 11 to heat the conveying chamber 111. A feed hopper 13 is provided at one end of the conveying pipeline. The feed hopper 13 is connected to the conveying chamber 111 and is located at the inlet end. Metal materials can be fed into the conveying chamber 111 through the feed hopper 13. The heating element 12 and the feed hopper 13 are existing technologies and can be purchased. Their specific structure and working principle will not be described in detail.
[0021] The conveying chamber 111 extends along the length of the conveying pipe 11. The conveying structure 2 is disposed within the conveying chamber 111, the push-pull structure 4 is disposed at one end of the conveying chamber 111 along its length, and the sealing structure 3 is disposed at the other end of the conveying chamber 111 along its length. The metering chamber 112 communicates with the conveying chamber 111 and is located at the end of the conveying chamber 111 away from the push-pull structure 4, i.e., the metering chamber 112 and the sealing structure 3 are located at the discharge end of the conveying chamber 111. The metering chamber 112 has a connecting port, which is located on one side of the metering chamber 112. In this embodiment, the connecting port is located on the upper side of the metering chamber 112. The sealing structure 3 is disposed at the connecting port and can close or open the connecting port.
[0022] The conveying structure 2 includes a conveying screw 21 rotatably connected to the conveying chamber 111 and a screw drive assembly 23 for driving the conveying screw 21 to rotate. The conveying screw 21 is located inside the conveying chamber 111 and is arranged along the length direction of the conveying chamber 111. One end of the conveying screw 21 in the length direction faces the metering chamber 112, and the other end of the conveying screw 21 in the length direction is connected to the screw drive assembly 23. In this embodiment, the conveying screw 21 is coaxially connected to a first connecting rod 22, and the screw drive assembly 23 is disposed on the first connecting rod 22. The screw drive assembly 23 includes a screw drive component, which can specifically be a motor and pulley structure, or a motor and gear structure. When the screw drive component is activated, it drives the first connecting rod 22 to rotate. The rotating first connecting rod 22 drives the conveying screw 21 to rotate, thereby continuously moving the molten material towards the metering chamber 112. It should be noted that the first connecting rod 22 and the conveying screw 21 can be coaxially connected by a coupling, in which case the first connecting rod 22 and the conveying screw 21 are two separate rods; the first connecting rod 22 and the conveying screw 21 can also be coaxially connected by integrating the first connecting rod 22 and the conveying screw 21 into one piece, that is, the first connecting rod 22 and the conveying screw 21 are the same rod.
[0023] Reference Figure 2 , Figure 3 as well as Figure 4The sealing structure 3 is located on one side of the metering chamber 112 and can be close to or away from the metering chamber 112. Specifically, the sealing structure 3 includes a sealing support 31 disposed on the conveying pipe 11, a sealing plug 32 slidably connected to the sealing support 31, and a sealing drive 33 for driving the sealing plug 32. The sealing support 31 is fixedly installed on the outer circumferential surface of the conveying pipe 11 to provide support for the sealing plug 32 and the sealing drive 33. The sealing drive 33 is a cylinder, hydraulic cylinder, or electric cylinder. The sealing drive 33 is fixed to the sealing support 31 and faces vertically downward. The sealing plug 32 is coaxially installed and fixed with the piston end of the sealing drive 33. The sealing plug 32 is slidably connected to the connecting port. Under the drive of the sealing drive 33, the sealing plug 32 abuts against or disengages from the connecting port to close or open the connecting port.
[0024] To prevent the closed drive component 33 from shifting during installation, the closed structure 3 also includes several closed guide rods 34 and a closed fixing seat 35 mounted on the closed support 31. One end of the closed guide rod 34 is fixed to the conveying pipe 11, and the other end of the closed guide rod 34 is fixedly connected to the closed fixing seat 35. The closed drive component 33 is disposed on the closed fixing seat 35. In this embodiment, there are two closed guide rods 34. The middle part of the closed guide rod 34 has a threaded part, which is fastened to the closed support 31 by a nut. Both ends of the closed guide rod 34 have smooth rod fixing parts. The smooth rod fixing part at one end of the closed guide rod 34 is fixed to the conveying pipe 11, and the smooth rod fixing part at the other end of the closed guide rod 34 is fixed to the closed fixing seat 35. With this setup, during installation, the two closed guide rods 34 are set vertically and the closed support base 31 is set horizontally. Using the closed guide rods 34 and the closed support base 31 as references, the closed fixing base 35 can be set horizontally after the closed guide rods 34 are installed. This ensures that the closed drive component 33 remains horizontal after installation, and its piston end is set vertically, thus ensuring its assembly accuracy.
[0025] Reference Figure 3 as well as Figure 5 It is worth mentioning that, in order to ensure a sealing effect, the end of the sealing plug 32 that mates with the communication port has a sealing end 321, and the communication port has a sealing part that mates with the sealing end 321. The shape of the sealing part is adapted to the shape of the sealing end 321. In this embodiment, both are conical. With this arrangement, when the sealing plug 32 is pressed against the communication port, it can fit tightly against the communication port, thereby ensuring a sealing effect.
[0026] Reference Figure 3 as well as Figure 6The push-pull structure 4 is located at the end of the conveying screw 21 away from the metering chamber 112 and connected to the conveying screw 21. The conveying screw 21 is slidably connected to the conveying chamber 111, allowing the conveying screw 21 to move closer to or further away from the metering chamber 112. The push-pull structure 4 is located at the end of the first connecting rod 22 away from the conveying screw 21. The push-pull structure 4 includes a connecting assembly 41 rotatably connected to the first connecting rod 22 and a push-drive assembly 42 for driving the connecting assembly 41. Specifically, in order to cooperate with the connecting assembly 41, the end of the first connecting rod 22 that cooperates with the connecting assembly 41 has an installation groove. The connecting assembly 41 includes a second connecting rod 411 passing through the installation groove. The push-drive assembly 42 is a cylinder, hydraulic cylinder, or electric cylinder. One end of the second connecting rod 411 in the length direction is coaxially mounted with the piston end of the push-drive assembly 42. Similarly, the second connecting rod 411 can be coaxially mounted with the piston end of the push-drive assembly 42 through a coupling. Alternatively, the second connecting rod 411 can be an integral structure with the piston end of the push-drive assembly 42.
[0027] The second connecting rod 411 is rotatably connected to a plurality of bearings 412 at one end of the mounting groove. The bearings 412 abut against the inner wall of the mounting groove, and the mounting groove is provided with a locking element for limiting the bearings 412. In this embodiment, in order to ensure the limiting and rotation effects, the second connecting rod 411 has a shoulder at one end of the mounting groove, which divides the mounting groove into two sub-mounting grooves, each of which is provided with bearings 412. With this arrangement, when the first connecting rod 22 rotates, the second connecting rod 411 remains independent. That is, the first connecting rod 22 is equivalent to the second connecting rod 411 rotating to drive the conveying screw 21 to rotate, while the second connecting rod 411 does not rotate, and the drive assembly 42 does not rotate either. The purpose of this arrangement is to avoid the failure of the drive assembly 42 due to prolonged rotation, thereby increasing the operational stability of the pulping mechanism.
[0028] Looking back Figure 5 Furthermore, to facilitate the transport of semi-solid metal, a guide block 113 is provided in the metering chamber 112. The guide block 113 is located at the end of the metering chamber 112 away from the conveying screw 21 and below the connecting port. The side of the guide block 113 near the connecting port has a guide slope 1131. With this arrangement, when the conveying screw 21 is driven to move by the drive assembly 42, the conveying screw 21 compresses the semi-solid metal towards the guide slope 1131. Under the guidance of the guide slope 1131, the semi-solid metal can move more smoothly to the connecting port for transport. It is understood that the specific inclination angle and shape of the guide slope 1131 can be adjusted according to actual needs.
[0029] When the magnesium alloy semi-solid quantitative pulping mechanism is running, metal raw materials are fed into the conveying pipe 11 through the feed hopper 13, while the heating element 12 operates and the sealing structure 3 closes the connection port. Driven by the conveying screw 21, the metal raw materials melt into a molten substance and continuously move towards the quantitative chamber 112. The push-pull structure 4 operates, pulling the conveying screw 21 away from the quantitative chamber 112. By controlling the pulling distance of the conveying screw 21, the volume of the quantitative chamber 112 can be controlled. When the quantitative chamber 112 reaches the preset size and is filled with molten substance, quantitative pulping is achieved. Finally, the sealing structure 3 opens the connection port, and the push-pull structure 4 pushes the conveying screw 21, which pushes the molten substance out of the quantitative chamber 112 for pulping and conveying, thus achieving quantitative conveying.
