Description

Technical Field

[0001] This application relates to the technical field of material toughening, and in particular to a material toughening molding apparatus. Background Technology

[0002] Currently, material toughening refers to adding toughening agents to the raw materials of a material. In the field of materials science and engineering, fracture toughness is a key mechanical property indicator that measures a material's ability to resist crack propagation. Many advanced materials with excellent strength, hardness, or specific functionalities (such as high-performance ceramics, brittle intermetallic compounds, cemented carbides, glass, and certain engineering plastics and composite matrices) often exhibit inherent brittle behavior. This brittleness means that the material lacks significant plastic deformation capacity before fracture, and tiny internal cracks or defects can easily and rapidly destabilize and propagate under stress, leading to catastrophic, unannounced, and sudden fracture failure.

[0003] Existing material toughening molding apparatuses generally include a frame, a screw extruder mounted on top of the frame, a hopper mounted on top of the frame and connected to the screw extruder, and a cooling water tank mounted outside the frame. The screw extruder includes an extrusion head, which is positioned corresponding to the cooling water tank. A cover plate is bolted to the top of the hopper, and a feeding pipe is connected to the top of the cover plate. A discharge pipe is connected to the bottom of the hopper, and the discharge pipe is connected to the screw extruder. The raw material and toughening agent mixture is added to the hopper through the feeding pipe, and then the raw material and toughening agent mixture is added to the screw extruder through the discharge pipe.

[0004] In the prior art, a certain proportion of crushed waste is sometimes mixed into the raw materials for the purpose of reusing waste. However, the waste can easily cause blockage of the discharge pipe. In the prior art, it is inconvenient to clear the blockage of the discharge pipe. Utility Model Content

[0005] This application provides a material toughening molding device that facilitates the unblocking of the discharge pipe, and adopts the following technical solution: A material toughening molding apparatus includes a frame, a screw extruder mounted on top of the frame, a hopper mounted on top of the frame and connected to the screw extruder, and a cooling water tank mounted outside the frame. A cover plate is bolted to the top of the hopper, and a feeding pipe is connected to the top of the cover plate. A discharge pipe is connected to the bottom of the hopper. A clearing mechanism for clearing the discharge pipe is installed inside the hopper. The clearing mechanism includes a horizontal plate mounted on the inner wall of the hopper, a mounting frame mounted on the bottom of the horizontal plate, and a vertical pipe mounted within the mounting frame. A moving rod is vertically slidably connected inside the vertical pipe, and a clearing rod is fixedly connected to the bottom of the moving rod. The bottom of the clearing rod can slide within the discharge pipe. A spring is sleeved on the clearing rod, and a support ring is threaded to the bottom of the vertical pipe. One end of the spring abuts against the bottom of the moving rod, and the other end abuts against the top of the support ring. A drive assembly for driving the moving rod to move vertically is installed on the side wall of the hopper.

[0006] Preferably, the drive assembly includes a mounting plate installed on the outer wall of the hopper, a drive motor installed on the top of the mounting plate, a horizontal shaft fixed to the output shaft of the drive motor, and a cam eccentrically connected to one end of the horizontal shaft; the top of the moving rod abuts against the outer peripheral surface of the cam.

[0007] Preferably, the vertical pipe is detachably connected to the mounting bracket via a connecting assembly.

[0008] Preferably, the connecting assembly includes a connecting ring fixed to one end of the mounting bracket away from the horizontal plate and sleeved on the outer wall of the vertical pipe, and two limiting rings threaded to the outer wall of the vertical pipe; the vertical pipe is fixedly connected to the connecting ring through the two limiting rings.

[0009] Preferably, a connecting plate is fixed to the bottom of the horizontal plate, and the connecting plate is bolted to the inner wall of the silo.

[0010] Preferably, a support plate is fixedly connected to the top of the horizontal plate, and the horizontal shaft is rotatably connected to the support plate.

[0011] Preferably, a threaded rod is fixed to one end of the horizontal shaft near the cam, a clearance groove is provided at the end of the cam away from the horizontal shaft, and the threaded rod is provided through the side wall of the clearance groove and threadedly connected to a limit nut at the other end of the threaded rod away from the horizontal shaft.

[0012] Preferably, a sealing ring is fixed to the inner wall of the top end of the vertical pipe.

[0013] In summary, this application has the following beneficial effects: When it is necessary to unclog the discharge pipe, the drive assembly first drives the moving rod downward, which in turn moves the unblocking rod downward. Furthermore, the downward movement of the moving rod presses against the spring. At this time, the moving rod can reciprocate under the combined action of the drive assembly and the spring. The reciprocating movement of the moving rod can drive the unblocking rod to reciprocate, thereby unblocking the discharge pipe. In summary, the unblocking mechanism facilitates the unblocking of the discharge pipe. Attached Figure Description

[0019] This application discloses a material toughening molding apparatus, such as Figure 1 and Figure 2 As shown, it includes a frame 1, a screw extruder 2 mounted on the top of the frame 1, a hopper 3 mounted on the top of the frame 1 and connected to the screw extruder 2, and a cooling water tank 4 mounted outside the frame 1; a cover plate 31 is bolted to the top of the hopper 3, a feeding pipe 32 is connected to the top of the cover plate 31, a discharge pipe 33 is connected to the bottom of the hopper 3, and a clearing mechanism 5 for clearing the discharge pipe 33 is installed inside the hopper 3.

One end of the spring 56 abuts against the bottom of the moving rod 54, and the other end abuts against the top of the support ring 57; a drive assembly 6 for driving the moving rod 54 to move vertically is installed on the side wall of the hopper 3. When it is necessary to unclog the discharge pipe 33, the moving rod 54 is first driven downward by the drive assembly 6. The downward movement of the moving rod 54 drives the unblocking rod 55 downward. Furthermore, the downward movement of the moving rod 54 presses against the spring 56. At this time, the moving rod 54 can reciprocate under the combined action of the drive assembly 6 and the spring 56. The reciprocating movement of the moving rod 54 can drive the unblocking rod 55 to reciprocate, thereby unblocking the discharge pipe 33. In summary, the unblocking mechanism 5 facilitates the unblocking of the discharge pipe 33.

When it is necessary to drive the moving rod 54 to move vertically, the drive motor 62 is started first. At this time, the output shaft of the drive motor 62 drives the horizontal shaft 63 to rotate, and the rotation of the horizontal shaft 63 drives the cam 64 to rotate. At this time, under the combined action of the cam 64 and the spring 56, the moving rod 54 can be driven to move vertically back and forth. In summary, the drive assembly 6 is designed to facilitate the vertical movement of the moving rod 54.

[0022] like Figure 2 As shown, the vertical pipe 53 is detachably connected to the mounting bracket 52 via the connecting assembly 7; the connecting assembly 7 facilitates the installation of the vertical pipe 53.

[0023] like Figure 2As shown, a connecting plate 511 is fixedly connected to the bottom of the horizontal plate 51. The connecting plate 511 is bolted to the inner wall of the hopper 3, which facilitates the installation of the horizontal plate 51. A support plate 512 is vertically fixed to the top of the horizontal plate 51. The horizontal shaft 63 is rotatably connected to the support plate 512 through a bearing.
