[0030] A discharging device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 , Figure 2 and Figure 3 A discharging device according to an embodiment of the utility model includes a hopper 100 and a blowing mechanism.

[0032] For the hopper 100, the hopper 100 has an inner cavity 110, and the inner cavity 110 runs through the hopper 100 from top to bottom. The inner cavity 110 gradually shrinks from top to bottom. The top of the inner cavity 110 has a feed port 120, and the bottom of the inner cavity 110 has a discharge port 130. Therefore, when the divided materials are unloaded, the divided materials enter the inner cavity 110 from the feed port 120 at the top of the inner cavity 110, and the side walls of the inner cavity 110 guide the divided materials to converge at the discharge port 130 for unloading, so that the discharge range of the divided materials is small, and thus it is convenient to load powder materials during unloading.

[0033] A cover 140 is further provided at the bottom of the hopper 100 , and the cover 140 is used to close and open the discharge port 130 .

[0034] It can be understood that when the unloading device is in use, the cover body 140 can be opened so that the discharge port 130 is open, thereby facilitating the discharge of the material from the discharge port 130; when the unloading device is idle, the cover body 140 can be closed so that the cover body 140 can seal the discharge port 130, thereby conveniently blocking dust or foreign matter from entering the inner cavity 110 from the discharge port 130.

[0035] In some specific embodiments, the cover body 140 is hinged to the hopper 100 via a hinge, and a buckle and a slot for snap connection are provided between the cover body 140 and the hopper 100, so as to facilitate opening and closing of the cover body 140.

[0036] As for the blowing mechanism, the blowing mechanism includes a mounting base 150 installed on the side wall of the hopper 100, an air nozzle 160 arranged on the mounting base 150, and an air supply assembly 170 for supplying air to the air nozzle 160. The air outlet end of the air nozzle 160 extends to the inner cavity 110, and the air nozzle 160 blows air into the powder in the inner cavity 110 to disperse the agglomerated powder.

[0037] It can be understood that the air supply component 170 supplies air to the air nozzle 160, so that the air nozzle 160 blows air into the powder in the inner cavity 110, thereby blowing away the accumulated powder, preventing the agglomerated powder from hindering the normal falling of powder or blocking the discharge port 130 during the unloading process, thereby keeping the unloading device from dropping smoothly and ensuring the unloading efficiency.

[0038] In some specific embodiments, at least four blowing mechanisms are provided, and the at least four blowing mechanisms are respectively distributed on the four side walls of the hopper 100, so that the four blowing mechanisms can blow air to the powder in the inner cavity 110 from different directions, thereby making the blowing mechanism more effective in dispersing the agglomerated powder.

[0039] In some specific embodiments, the air outlet end of the air nozzle 160 is provided with at least two air outlets 180, at least one of which is oriented toward the center of the inner cavity 110, and at least one of which is oriented toward the discharge port 130, so that the air nozzle 160 can simultaneously blow away the powder in the falling process in the inner cavity 110 and the powder accumulated at the discharge port 130, thereby making the air nozzle 160 have a larger blowing range for the powder in the inner cavity 110, thereby improving the efficiency of the air nozzle 160 in blowing away the agglomerated powder in the inner cavity 110.

[0040] In some specific embodiments, the mounting seat 150 can be removably installed on the side wall of the hopper 100. The side wall of the hopper 100 is provided with a first mounting hole 190 that passes through the inner cavity 110. The first mounting hole 190 is used to install the mounting seat 150. The first mounting hole 190 has an internal thread. The mounting seat 150 is provided with an external threaded portion 200, and the external threaded portion 200 is connected with the internal thread. Therefore, the mounting seat 150 can be installed in or removed from the first mounting hole 190 by turning the knob mounting seat 150, thereby facilitating the removal, cleaning and replacement of the blowing mechanism.

[0041] Furthermore, an end of the first mounting hole 190 close to the inner cavity 110 has an inner convex ring 210, which is used to limit the outer threaded portion 200, thereby preventing the mounting seat 150 from being inserted too deep into the first mounting hole 190 and falling into the inner cavity 110.

[0042] In some specific embodiments, a sealing ring 220 is provided on the side of the inner convex ring 210 away from the inner cavity 110 , and the sealing ring 220 abuts and seals against the external threaded portion 200 , thereby making the sealing between the hopper 100 and the mounting seat 150 better and preventing powder from leaking from the first mounting hole 190 .

[0043] In some specific embodiments, the air nozzle 160 is rotatably connected to the mounting base 150, so that when the mounting base 150 rotates in the first mounting hole 190, the air nozzle 160 can be stationary relative to the hopper 100 to avoid affecting the connection between the air supply assembly 170 and the air nozzle 160. Furthermore, when the mounting base 150 is rotated to remove the blowing mechanism, the air supply assembly 170 can be avoided from being disassembled, making the disassembly and installation of the blowing mechanism more convenient.

[0044] In some specific embodiments, a ferrule 230 is mounted on the outer surface of the air nozzle 160. The ferrule 230 is slidably connected to the air nozzle 160 along the direction of the rotation axis of the mounting seat 150. One end of the ferrule 230 has a first mating portion 240, and the mounting seat 150 has a second mating portion 250. The ferrule 230 slides to bring the first mating portion 240 and the second mating portion 250 closer to and farther away from each other, and the first mating portion 240 and the second mating portion 250 cooperate to stop rotation.

[0045] It can be understood that by sliding the sleeve 230, the sleeve 230 can be moved closer to and away from the mounting seat 150, so that the sleeve 230 drives the first matching part 240 to move closer to and away from the second matching part 250. When the mounting seat 150 needs to be rotated, the sleeve 230 is slid to disengage the first matching part 240 and the second matching part 250 from each other, thereby allowing the mounting seat 150 to rotate relative to the air nozzle 160. When the mounting seat 150 does not need to be rotated, the sleeve 230 is moved closer to the mounting seat 150 to make the first matching part 240 and the second matching part 250 move closer to and match to stop rotation, thereby preventing the air nozzle 160 from rotating and changing the blowing direction during use.

[0046] In some specific embodiments, a first spring 260 is also mounted outside the air nozzle 160, one end of the first spring 260 abuts against the air nozzle 160, and the other end of the first spring 260 abuts against the ferrule 230. The first spring 260 is used to drive the ferrule 230 to squeeze the mounting seat 150, so that the first spring 260 can drive the ferrule 230 to continuously squeeze the mounting seat 150, thereby preventing the first matching part 240 and the second matching part 250 from being separated from each other when the unloading device is working, thereby affecting the use effect.

[0047] Specifically, one end of the air nozzle 160 away from the air outlet 180 has an outer convex ring, and the first spring 260 abuts against the outer convex ring.

[0048] In some specific embodiments, the first mating portion 240 and the second mating portion 250 are both configured as anti-slip pads with the rotation axis of the mounting seat 150 as the central axis, and the first mating portion 240 and the second mating portion 250 abut against each other for friction to stop rotation, so that the first mating portion 240 and the second mating portion 250 can cooperate with each other when the mounting seat 150 and the air nozzle 160 are rotated to any angle.

[0049] In some specific embodiments, the first matching portion 240 is tilted in a direction close to the rotation axis of the mounting seat 150, and the second matching portion 250 is tilted correspondingly, so that the abutment fit between the first matching portion 240 and the second matching portion 250 is tighter.

[0050] In some specific embodiments, the air supply assembly 170 includes an air pump and an air pipe, and the air pipe connects the air pump and the air nozzle 160 .

[0051] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0052] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
