DETAILED DESCRIPTION

[0030] Example:

[0031] The following is combined with Figure 1-3 The utility model is described in further detail.

[0032] Uniform speed dumbbell plate pressing equipment, such as Figure 1 As shown, it includes a material mixing mechanism 10, a feeding mechanism 20, a material dropping mechanism 30 and a material pressing mechanism 40. The main body of the material mixing mechanism 10 is a material dropping frame, and a material dropping port 12 is opened on the top of the material mixing mechanism 10, and iron filings mixed with gelling agent are fed in from the material dropping port 12. A material shaking unit is arranged inside the material mixing mechanism 10, which is mainly a vibration motor, which vibrates the material dropping frame so that the iron filings are transported forward in a jumping manner. Specifically, the iron filings fall into the material mixing mechanism 10, accumulate slowly, and continue to spread to the discharge end as the accumulation continues. With the vibration of the material shaking unit, the iron filings are leveled while being transported, and are continuously and stably transported to the next mechanism. A material shaking platform 11 is arranged at the lower part of the rear end face of the material mixing mechanism 10, and a material dropping trough is opened at the corresponding position of the material mixing mechanism 10. The material dropping trough is connected to the material shaking platform 11, so that the iron filings inside can fall onto the material shaking platform 11 at a uniform speed. The material shaking platform 11 is a dustpan structure and vibrates. The iron filings that fall onto the material shaking platform 11 also fall toward the upward material mechanism 20 at a uniform speed.

[0033] The feeding mechanism 20 is divided into two large screening units and a feeding unit. The head end of the screening unit is located below the material shaking platform 11, and the tail end of the screening unit is docked with the feeding unit. The screening unit includes a receiving platform 21 and a screening net 22. The receiving platform 21 is a rectangular topless trough body with a deep groove in the center. A conveyor belt is arranged in the deep groove, and the end of the receiving platform 21 is fitted and docked with the feeding unit. The part of the receiving platform 21 that is not docked with the feeding unit is installed with a screening net 22, which is mainly located at the top of the front end of the receiving platform 21 and directly below the material shaking platform 11. The iron filings that fall from the material shaking platform 11 at a uniform speed fall onto the screening net 22, and the large particles are screened out. The iron filings of qualified size continue to fall into the deep groove and are transported to the feeding unit under the drive of the conveyor belt. The feeding unit includes a feeding pipe 23 and a feeding roll belt 25. The feeding pipe 23 is an inverted U-shaped structure, one end of which is fitted and docked with the end of the receiving platform 21, and the other end is fixed in mid-air by a support frame 24, leaving space for the blanking mechanism 30 to rotate. A corresponding feeding roll belt 25 is arranged in the feeding pipe 23, and the feeding roll belt 25 is arranged parallel to the corresponding section of the receiving pipe. The feeding roll belt 25 is a special conveyor belt or conveyor chain mechanism. The feeding roll belt 25 is the first connected conveying mechanism, and a number of inclined rolls 26 arranged at equal intervals are arranged on the surface, so that the inclined rolls 26 are driven by the feeding roll belt 25 to perform a reciprocating transmission action inside the receiving pipe. The angle between the inclined coil 26 and the feeding coil belt 25 is not greater than 60°. Here, taking the vertical section docking with the receiving platform 21 as an example, the inclined coil 26 and the feeding coil belt 25 are arranged at a certain angle to form a receiving structure that opens obliquely upward, and "scoops" out an equal amount of iron filings from the pile at the bottom, and transfers them to the blanking mechanism 30 along with the feeding coil belt 25. A material hopper 27 is provided at the end where the feeding pipe 23 and the support frame 24 are connected, and the material hopper 27 is connected to the upper end of the blanking mechanism 30. The gathered iron filings are transferred to the blanking mechanism 30.

[0034] like Figure 2 and Figure 3As shown, the blanking mechanism 30 includes a blanking chute 31, a focusing funnel 32 and an annular leak cup 33. The blanking chute 31 is rotatably connected to a suitable position of the support frame 24 and is equipped with a motor for driving. Because of the rotation of the blanking chute 31, it is necessary to add a focusing funnel 32 at the upper end of the blanking chute 31. The focusing funnel 32 and the whole material funnel 27 are not directly connected, but the focusing funnel 32 covers the whole material funnel 27 during the entire rotation process to prevent iron filings from spilling from the junction. An integrally formed annular leak cup 33 is also provided at the end of the blanking chute 31. This is for shaping guidance so that the iron filings can evenly form the prototype of an annular discus after continuing to fall. The annular leak cup 33 is connected from top to bottom and is connected to the chute groove of the blanking chute 31 to ensure that the iron filings naturally slide down the blanking chute 31 and smoothly pass through the annular leak cup 33 and fall into the pressing cavity 41 of the pressing mechanism 40. The blanking chute 31 is lifted up to the level of the annular leak cup 33, at which time the annular leak cup 33 is directly above the pressing chamber 41 of the pressing mechanism 40; after the blanking chute 31 is pressed down, it is ensured that the squeezing column 42 and related platforms of the hydraulic unit on the subsequent pressing mechanism 40 will not be hindered and affected by the blanking chute 31 when they are pressed down.

[0035] The pressing mechanism 40 is provided with a pressing chamber 41, a heating unit and a hydraulic unit. The pressing chamber 41 is a place where iron filings are compacted into discus under the action of external pressure. The extrusion column 42 of the hydraulic unit is directly opposite to the pressing chamber 41, and the heating unit is arranged in the extrusion column 42. The hydraulic mechanism drives the extrusion column 42 to press the material downward along the pressing chamber 41, and the evenly distributed iron filings are continuously heated and compacted into an annular discus. A discharge port 43 is provided at the bottom of the pressing mechanism 40, and the discharge port 43 is connected to the bottom of the pressing chamber 41, and the compacted discus is pushed out from the bottom of the pressing chamber 41. A lining plate that can be pushed forward and backward is provided at the bottom of the pressing chamber 41. The lining plate serves as a base when pressing the material and is removed after the pressing is completed. After the discus falls, it is pushed out from the discharge port.

[0036] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
