[0047] Embodiment 1:

[0048] See also Figure 1-4 The present invention provides a technical solution: a dough automatic powder sprinkling device with controllable discharge, comprising:

[0049] Device base 1;

[0050] A dough conveying mechanism 2, which is arranged on the device base 1;

[0051] The powder conveying mechanism 3 is elevated on the dough conveying mechanism 2 by means of a first bracket 21; both conveying mechanisms are composed of a conveyor belt, a transmission roller, and a rotating drive device, and the surface of the conveyor belt is smooth;

[0052] A powder stirring mechanism 4 is arranged on the powder conveying mechanism 3, wherein a stirring rod 42 is rotatably arranged in a stirring tank 41 therein, and a plurality of discharge ports 43 are arranged at the bottom of the stirring tank 41;

[0053] The powder spreading mechanism 5 is arranged on the connecting pipe 44 at the bottom of the powder stirring mechanism 4, and comprises a suction pipe 51, a spreading shell 52 and a linkage plate 53. The suction pipe 51 is rotatably and sealedly assembled on the connecting pipe 44 through a convex rib 511 at one end, and a suction chamber 512 therein is connected to the discharge port 43. A discharge groove 513 is arranged on one side of the outer surface of the suction pipe 51. The other end of the suction pipe 51 is sealed and inserted into a pressure-changing chamber 521 on one side of the spreading shell 52, and the pressure-changing chamber 521 is connected to the discharge groove 513. A discharge hole 523 corresponding to the discharge groove 513 is arranged on the spreading shell 52. The linkage plate 53 is elastically hinged in a notch 522 on the surface of the spreading shell 52. A clamping block 532 is arranged on one end of the suction pipe 51. A clamping groove 514 corresponding to the clamping block 532 is arranged on the suction pipe 51.

[0054] A material extraction drive mechanism 6, which is used to drive the suction pipe 51 and the material spreading shell 52 to move relative to each other in the axial direction;

[0055] The powder spreading driving mechanism 7 is used to drive the powder spreading mechanism 5 to rotate.

[0056] The automatic powder sprinkling device of the present invention conveys dough and powder in layers respectively through two conveying mechanisms arranged upper and lower, and throws the powder in the powder stirring mechanism onto the powder conveying mechanism in a uniform and controllable manner through the powder sprinkling mechanism, and then delivers the powder to the dough conveying mechanism through the powder sprinkling mechanism for secondary powder sprinkling, thereby further improving the uniformity of the powder on the dough; wherein, the linkage plate adopts a seesaw arrangement to cooperate with the rotation drive of the sprinkling drive mechanism to switch the connection state of the suction tube and the sprinkling shell, thereby realizing the switching of the negative pressure powder suction and rotation powder throwing use states of the powder sprinkling mechanism, thereby improving the efficiency and controllability of the powder sprinkling.

[0057] The powder conveying mechanism 3 includes a main conveyor belt assembly and a secondary conveyor belt assembly 31 arranged on the side of the main conveyor belt assembly, the main conveyor belt assembly is connected to at least one conveying roller of the secondary conveyor belt assembly 31, and the secondary conveyor belt assembly 31 is connected to a rotation drive device. The above-mentioned conveyor belt assembly is also composed of a conveyor belt, a transmission roller, and a rotation drive device. This design improves the stability of the powder conveying mechanism 3 in powder conveying, avoids the vibration of the mechanism, causes the powder to be lifted, and causes material loss, pollution of the production workshop, and dust explosion hazards.

[0058] One end of the stirring rod 42 is rotatably set on the side wall of the stirring tank 41, and the other end thereof passes through the powder stirring mechanism 4, is sealed and docked with the bearing seat 45 and the output shaft of the driving device, and the driving device is positioned on the side of the powder conveying mechanism 3 through the L-shaped support 32 to improve the stability of the stirring rod 42, improve the stirring effect, and ensure that the dough is loose.

[0059] The bottom of the discharge trough 513 and the side of the transformer chamber 521 corresponding to the discharge hole 523 are both provided with opposite wedge-shaped guide surfaces, so that the scattering drive mechanism 7 drives the powder scattering mechanism 5 to rotate, and the linkage plate 53 positions the suction pipe 51 and the scattering shell 52. When the discharge trough 513 is connected to the discharge hole 523 to scatter the powder, the powder in the transformer chamber 521 can be fully and completely discharged through the guiding effect of the wedge-shaped guide surfaces of the two, thereby ensuring the scattering efficiency.

[0060] The linkage plate 53 is rotatably connected to the shaft passing through the notch 522 through the inner hinge ear, and its center of gravity is offset from its hinge. The elastic member 531 in the notch 522 applies an elastic pre-tightening force to the linkage plate 53 to rotate toward one side. The above design is mainly used to cooperate with the rotation drive of the material spreading drive mechanism 7 to switch the connection state of the suction pipe 51 and the material spreading shell 52. The specific mechanism is that when the material spreading drive mechanism 7 is not running, the elastic force of the elastic member 531 causes the linkage plate 53 to rotate, and the clamping block 532 is separated from the clamping groove 514. At this time, the suction pipe 51 and the material spreading shell 52 can move relatively, and the discharge groove 513 and the discharge hole 523 are staggered, so that the pressure-changing chamber 521 is closed, and the material extraction drive mechanism 6 can be used to drive the suction pipe 51 and the material spreading shell 52 to move relatively, so that the pressure-changing chamber 521 is expanded, and negative pressure is formed inside, thereby making the powder in the powder stirring mechanism 4 pass through the stirring groove 41, the discharge port 43, the inner cavity of the connecting pipe 44, and the suction cavity 512, Press into the pressure-changing chamber 521, as shown in the specific Figure 3 As shown; thereafter, the material spreading driving mechanism 7 can be used to drive the material spreading shell 52 to rotate, so that the block 532 and the slot 514 move to relative positions, and the rotation of the material spreading shell 52 synchronously drives the linkage plate 53 to rotate along the same axis. Because the center of gravity and the hinge on the linkage plate 53 are staggered, it overcomes the elastic force of the elastic member 531 under the action of centrifugation and rotates along the rotating shaft, so that the block 532 and the slot 514 are docked and positioned, the suction pipe 51 and the material spreading shell 52 are positioned, and the discharge groove 513 is docked with the discharge hole 523. When the powder spreading mechanism 5 rotates, the powder is thrown onto the powder conveying mechanism 3, as shown in the figure. Figure 4 As shown; because the center of gravity of the linkage plate 53 deviates from its hinge, the elastic member 531 in the notch 522 applies an elastic preload force to the linkage plate 53 to rotate toward one side. When the material spreading drive mechanism 7 just starts to operate and the speed is low and unstable, the centrifugal effect is small, and the suction pipe 51 and the material spreading shell 52 are not docked and positioned. When the drive mechanism is stable and the speed is sufficient, the centrifugal effect is greater than the preload force provided by the elastic member 531, thereby realizing the structural positioning of the powder spreading mechanism 5. This design can avoid the influence of the poor stability in the initial stage of equipment operation on the uniformity of material spreading, so that when the equipment is operating normally, the powder can be spread to ensure the quality of material spreading.

[0061] The material extraction drive mechanism 6 includes a telescopic drive device, a plurality of slides 61 connected to the telescopic drive device, and a guide rail 62 slidably connected to the slides 61. Adjacent slides 61 are connected via a connecting plate 63. The material spreading drive mechanism 7 is positioned on the slides 61, and its output shaft is connected to the outside of the material spreading shell 52. The guide rail 62 is located on the side of the powder spreading mechanism 5. The above-mentioned drive device adopts a motor, a cylinder or a hydraulic cylinder with a corresponding activity mode.

In addition, in order to ensure the use safety of the above-mentioned design, a static-eliminating component should be arranged in the transformer chamber 521 to avoid dust explosion in a confined space.

This design allows the extraction length of the material spreading shell 52 to be adjusted by the extraction drive mechanism 6, thereby adjusting the amount of powder drawn into the pressure-changing chamber 521. Under different extraction amounts, the clamping block 532 corresponds to different clamping grooves 514, thereby improving the controllability of the powder discharge.
