[0003] The Chinese utility model patent with announcement number CN207580772U discloses a material drop buffer device, which buffers the material falling onto the material receiving plate by arranging a spring under the hinged and rotatable material receiving plate. However, the material receiving plate designed is still of the nature of transfer feeding, and the material receiving point is still on the high-position plate body, and the material receiving range cannot be expanded. In addition, due to the disorder of the falling of workpieces, the dropped materials will be unevenly stacked and chaotically stacked, which is not conducive to space utilization and safe operation. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the utility model discloses a buffering and noise-reducing regular blanking device, which can always maintain a large buffering material receiving interval and orderly regularize the blanking.

[0005] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0006] A buffering and noise-reducing regular blanking device comprises a fixed vertical plate and a movable baffle, wherein the top end of the fixed vertical plate is rotatably connected to one end of the movable baffle via a rotating shaft, so that the movable baffle can rotate to an opening and closing angle corresponding to the plate surface of the fixed vertical plate; an arc-shaped baffle with the axis of the rotating shaft as the virtual center line is arranged below the movable baffle, and the other end of the movable baffle presses against the inner plate surface of the arc-shaped baffle, so that a material-receiving space is formed between the upper plate surface of the movable baffle and the inner plate surface of the arc-shaped baffle, and a spring is connected between the lower plate surface of the movable baffle and the plate body of the fixed vertical plate.

[0007] Furthermore, the outer plate surface of the arc-shaped baffle is supported and connected with a supporting vertical plate, and a bottom plate is connected between the lower end of the supporting vertical plate and the lower end of the fixed vertical plate.

[0008] Furthermore, the opening and closing angle range of the movable baffle and the fixed vertical plate is 0 to 90 degrees.

[0009] Furthermore, the plate surface of the fixed vertical plate is provided with a limit through hole whose body is curved in an arc with the axis of the rotating shaft as the virtual center line, and an arc guide rod is adapted to be movably penetrated in the limit through hole, and the corresponding end of the arc guide rod is fixedly connected to the lower plate surface of the movable baffle plate, and the spring is sleeved on the arc guide rod body located between the movable baffle plate and the fixed vertical plate.

[0010] Furthermore, a plurality of the limiting through holes are vertically spaced apart along the fixed vertical plate.

[0011] Furthermore, a guide sleeve adapted for sliding through the arc-shaped guide rod is fixed on the plate surface of the fixed vertical plate corresponding to the movable baffle, and the two ends of the spring are fixedly connected to the movable baffle and the guide sleeve respectively.

[0012] Furthermore, the rod end of the arc guide rod away from the movable baffle is connected to a guard plate after passing through the limiting through hole.

[0013] Furthermore, two mounting plates are symmetrically provided at both ends of the top end surface of the fixed vertical plate, and both ends of the rotating shaft are rotatably mounted on the two mounting plates through bearings respectively, and the movable baffle is fixedly connected to the rotating shaft.

[0014] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0015] The buffering and noise-reducing device for regular blanking disclosed by the utility model also utilizes a rotatably connected movable baffle, which is supported by a spring to achieve the effect of traditional blanking buffering, and the design of the arc-shaped baffle and the movable baffle cooperating to form a constantly changing pointed-bottom fan-shaped material-receiving space can enable the movable baffle itself to serve as a high-position large-plane material-receiving interval for buffering and noise reduction when there is no material. After blanking, although the movable baffle is tilted, the converged workpieces and the movable baffle together maintain a high-position large-plane material-receiving interval, and the movable baffle that is tilted due to the force of blanking also plays a role in regularizing the blanked workpieces together with the arc-shaped baffle. In summary, compared with the prior art, the utility model can always maintain a larger buffer material-receiving interval and orderly regularize the blanking, thereby improving space utilization and achieving safe operation.

[0020] Combined with Figure 1-2 The buffering and noise-reducing regular blanking device comprises a fixed vertical plate 1 and a movable baffle 4. The top end of the fixed vertical plate 1 is rotatably connected to one end of the movable baffle 4 through a rotating shaft 3, so that the movable baffle 4 can rotate to an opening and closing angle relative to the plate surface of the fixed vertical plate 1; as needed, two mounting plates are symmetrically provided at both ends of the top end surface of the fixed vertical plate 1, and the two ends of the rotating shaft 3 are rotatably mounted on the two mounting plates through bearings respectively, and the movable baffle 4 is fixedly connected to the rotating shaft 3 to ensure the connection stability and rotation flexibility of the movable baffle 4; in addition, the opening and closing angle range of the movable baffle 4 and the fixed vertical plate 1 is 0 to 90 degrees, so that when the material is empty, the movable baffle 4 remains horizontal and has the maximum material storage space at 0 degrees;

[0021] An arc-shaped baffle 6 with the axis of the rotating shaft 3 as the virtual center line is set below the movable baffle 4. The lower end of the arc-shaped baffle 6 can be directly connected to the fixed vertical plate 1, or, as needed, a supporting vertical plate 5 is supported and connected to the outer plate surface of the arc-shaped baffle 6, and a bottom plate 9 is connected between the lower end of the supporting vertical plate 5 and the lower end of the fixed vertical plate 1, thereby maintaining the supporting stability of the entire structure; the other end of the movable baffle 4 is pressed against the inner plate surface of the arc-shaped baffle 6, so that a material-bearing space is formed between the upper plate surface of the movable baffle 4 and the inner plate surface of the arc-shaped baffle 6, and the end of the movable baffle 4 can be in frictional contact with the inner plate surface of the arc-shaped baffle 6, or a gap smaller than the diameter of the long workpiece is left, thereby forming a constantly changing pointed-bottom fan-shaped material-bearing space, and a spring 7 is connected between the lower plate surface of the movable baffle 4 and the plate body of the fixed vertical plate 1, and the spring 7 is used to support the movable baffle 4, so as to buffer the falling material carried by the movable baffle 4.

[0022] When implementing the buffering and noise-reducing regular blanking device of the utility model, the blanking point can be selected at any position on the upper surface of the movable baffle 4 when the material is empty. Once the material is blanked, the movable baffle 4 is forced to rotate and tilt downward, and the blanked workpiece will also roll toward the arc-shaped baffle 6, thereby ensuring the orderly arrangement of the workpieces. The blanking that is continuously gathered between the movable baffle 4 and the arc-shaped baffle 6 can also better maintain the initial blanking material difference, thereby always maintaining the buffering and noise reduction effect.
