TECHNICAL FIELD

[0001] The utility model belongs to the technical field of blanking device relates to a powder's blanking device. BACKGROUND

[0002] The printing ink is usually needed to send the raw material powder into the reaction chamber through the blanking device when producing, the raw material powder is a big bag, so needs the blanking device to carry out the blanking, the blanking device is provided with the hopper -shaped blanking hopper, and the raw material powder is guided, but the setting of the blanking hopper can cause the raw material powder to be easily blocked at the blanking port, so that the blanking is not smooth, and the staff needs to dredge continuously.

[0003] In view of the above situation, people develop like Chinese patent application authorized announcement number

CN213612548U

[0004] The above structure is vibrated by spring, so that powder is no longer blocked sieve hole, realizes the quick screening of powder and blanking, but in the process of powder pouring, powder is easily raised to form dust, causes pollution to working environment, affects the working environment of staff. UTILITY MODEL CONTENT

[0005] The utility model aims at the above-mentioned problems existing in prior art, and provides a powder blanking device, and the technical problem to be solved by the utility model is how to solve the problem that the existing blanking device pollutes the working environment seriously when blanking.

[0006] The purpose of the utility model can be achieved by the following technical solutions.

[0007] A powder feeding device includes multiple support legs and a feeding hopper disposed above the support legs. The lower end of the feeding hopper is connected to the support legs by a support spring. The device is characterized in that a dust collection plate is connected to the upper end of the feeding hopper. The dust collection plate has multiple dust collection holes. The dust collection plate is a U-shaped plate. All dust collection plates are covered with dust collection covers. The outer wall of the dust collection plate and the dust collection covers together form a U-shaped dust collection cavity. The outer wall of the dust collection cover has a pipe joint communicating with the dust collection cavity.

[0008] The bagged powder is placed on the hopper, and the bag is pulled to pour the powder into the hopper. If the powder blocks the outlet of the hopper during the pouring process, the dust suction plate can be manually pressed down. The dust suction plate and the hopper move downwards synchronously, and the spring in the hopper depresses. After the pressure is released, the spring can cause the hopper to shake, making it easier for the powder blocking the outlet to be discharged. In order to improve the working environment, this structure is equipped with a dust suction plate. The shape of the dust suction plate makes it easy for workers to place the bag containing powder on the hopper. A dust suction chamber is formed between the dust suction plate and the dust suction hood. Multiple dust suction holes are opened on the dust suction plate. The dust raised by the powder is sucked into the dust suction chamber by an external vacuum cleaner and then sucked out through the external pipe connected to the pipe connector. This improves the working environment and reduces the impact of dust on workers.

[0009] In the powder feeding device described above, the upper part of the dust suction plate is located outside the dust suction hood.

[0010] This structure allows the dustproof plate to further block the higher-flying dust particles within the opening slot, thus improving the dust reduction effect of the feeding device.

[0011] In the powder feeding device described above, the feeding hopper includes a square support plate, and the dust collection plate is placed on the support plate.

[0012] This design allows the dust collection plate to be stably mounted on the support plate, ensuring convenient powder feeding while reducing dust generation.

[0013] In the powder feeding device described above, the dust collection plate has a limiting baffle. The feeding device also includes a placement plate. The feeding hopper includes an upward-opening inlet and a downward-opening outlet. The outside of the placement plate can be placed on the limiting baffle and block the inlet.

[0014] The setting of the placing plate makes the bag containing powder placed on the placing plate first, avoids the bag sliding out of the discharge port of the discharge hopper, and then the powder in the bag is poured out, and then the placing plate is pulled out, thereby improving the discharging efficiency; and when all the powder is in the discharge hopper, the placing plate can be covered, so that the dust raised by the powder in the discharge process is prevented from being raised out of the discharge hopper, the influence of the raised dust on the workers is further reduced, and the working environment is improved.

[0015] In the powder discharging device, a plurality of limiting edges are arranged on the inner wall of the dust collection plate in a circumferential direction.

[0016] The limiting edges make the placing of the placing plate more stable.

[0017] In the powder discharging device, a handle is connected to the placing plate.

[0018] The handle is arranged to facilitate the workers to pull out the placing plate quickly.

[0019] In the powder discharging device, a mounting leg corresponding to each supporting leg is arranged at each corner of the discharge hopper, the upper end of the supporting spring is embedded in the mounting leg, and the lower end of the supporting spring is sleeved on the supporting leg.

[0020] The mounting leg makes the mounting of the supporting spring more convenient, and the mounting leg arranged at the discharge hopper can ensure that the discharge hopper can shake up and down under the action of the supporting spring, and can also avoid large left and right tilting, thereby improving the stability of the discharging of the discharging device.

[0021] Compared with the prior art, the powder discharging device has the following advantages: in order to improve the working environment, the dust collection plate is arranged, the opening groove of the dust collection plate is arranged, the worker can place the bag containing powder on the discharge hopper, the dust collection cavity is formed between the dust collection plate and the dust collection cover, a plurality of dust collection holes are arranged on the dust collection plate, the dust raised by the powder is sucked into the dust collection cavity by an external dust collector, and the external pipe connected by the pipe joint is used to suck out the dust, thereby improving the working environment during work and reducing the influence of the dust on the workers.
