Description

TECHNICAL FIELD

[0001] The utility model relates to powder processing technical field, specifically, relate to a powder feeding device that prevents dust splashing. BACKGROUND

[0002] Powder refers to the appearance of powder for producing and processing into corresponding product raw material, when the powder is processed, the powder feeding device is needed to feed the powder, and the powder feeding device plays a very important role in the production and processing of the powder.

[0003] However, the powder feeding device is usually used, and the powder is easy to scatter during feeding in the actual use process.

[0004] The utility model discloses a kind of powder feeding devices that avoid powder scattering, including feeding tank, two-way motor is installed in the middle part of the feeding tank, screen, the screen is fixedly connected in the middle part of mounting frame, and mounting frame is fixedly connected in the outside of the connecting rod in horizontal state, the mounting frame and screen are arranged on the outer side wall of connecting rod at equal angles, limiting mechanism, the limiting mechanism is arranged at the edge of protective baffle at equal angles.

[0005] The structure realizes the effect of preventing dust scattering by protective baffle covering top, but its top is still provided with a connecting port to communicate inside for facilitating feeding, and the dust inside can still be scattered outward through the connecting port above, and the anti-scattering effect is not good enough, if cover is added on the connecting port, the cover is removed every time feeding, it is troublesome. UTILITY MODEL CONTENTS

[0006] In summary, in order to overcome the deficiencies of the prior art, the utility model provides a powder feeding device that prevents dust scattering and does not affect feeding.

[0007] To achieve the above purpose, the utility model provides the following technical scheme: a powder feeding device that prevents dust scattering, including feeding tank and protective baffle, the protective baffle is detachably connected with the top of the feeding tank, the protective baffle is provided with a feeding port communicating with the inside of the feeding tank, the bottom of the feeding tank is provided with a feeding cylinder, the two sides of the width direction of one end of the feeding port facing the feeding tank are respectively provided with a top plate and a bottom plate, the top plate and the bottom plate are inclinedly arranged towards the same side wall of the feeding tank, and the distance between the bottom of the bottom plate and the side wall in the inclined direction is greater than the distance between the top plate and the side wall.

[0008] In this way, when in use, the powder can be poured from the position of the feeding opening, and after being poured, the powder will first fall on the bottom plate and then slide down along the inclined bottom plate until sliding into the feeding box, without affecting the feeding process. When the powder in the feeding box is driven by the feeding push plate and other parts and dust is raised, due to the inclined arrangement of the bottom plate, part of the dust raised in the feeding box will directly hit the bottom surface of the bottom plate and slide along the inclined surface to the position on the bottom surface of the protective baffle outside the feeding opening, and will not be scattered from the position of the feeding opening. Due to the fact that the distance between the bottom of the bottom plate and the side wall in the inclined direction is greater than the distance between the top plate and the side wall, the dust floating upwards from the outside of the bottom plate will not directly hit the top plate, but will first hit the bottom surface of the protective baffle. This part of the dust will be blocked by the top surface of the top plate when floating towards the position of the feeding opening, and cannot pass through the feeding opening. The dust blocked by the top plate and the bottom plate reduces the flying of dust and does not affect the feeding process. The protective baffle and the feeding box can be connected by using a conventional thread connection or a bolt and nut structure.

[0009] Further, the bottom plate is a flat plate, the top plate is a circular arc shape concave towards the bottom plate, and the bottom of the top plate is raised.

[0010] In this way, the flat bottom plate does not affect the pouring process of the powder, and the circular arc raised top plate can cover the powder, further reducing the possibility of the powder sliding down along the top plate and entering the feeding opening from below.

[0011] Further, the distance between the bottom of the bottom plate and the top plate is less than the width of the top and bottom.

[0012] In this way, the two form a conical shape, facilitating pouring and reducing the possibility of dust entering from the bottom.

[0013] Further, the two sides of the length direction of the end of the feeding opening facing the feeding box are respectively provided with a side plate, the two side plates are respectively connected with the top plate and the bottom plate, and a gap is arranged between the side plates and the inner wall of the feeding box.

[0014] In this way, the two side plates, the top plate and the bottom plate form a complete whole, further reducing the possibility of dust entering, and the gap between the side plates and the inner wall of the feeding box can prevent scratching when the protective baffle is connected, which is more convenient.

[0015] Further, the top plate, the bottom plate, the side plate and the protective baffle are separately arranged, and the top of the top plate, the bottom plate and the side plate is provided with a connecting ring cover.

[0016] In this way, the top plate, the bottom plate, the side plate and the connecting ring cover can be separately processed into one part, and only one feeding opening can be arranged on the protective baffle, which is more convenient to process.

[0017] Further, the connecting ring cover is connected with the protective baffle by bolts.

[0018] In this way, bolts are used for connection, threaded holes or through holes are arranged on the two, the bolts are passed through the two for connection, and nuts can be additionally arranged for auxiliary connection, so that the structure is simple and the installation is convenient.

[0019] Further, the bottom of the top plate is provided with a swing piece, and the width of the swing piece is greater than the distance between the bottom plate and the bottom of the top plate.

[0020] In this way, the swing piece covers the opening position at the bottom of the top plate and the bottom plate, the swing piece is lifted up when the powder is loaded, and the powder enters normally, and after the loading is completed, the swing piece covers the opening, so that the dust is prevented from entering, and the dust prevention is more thorough.

[0021] Further, the swing piece is made of cloth.

[0022] In this way, the cloth is light in weight and is more easily lifted up, and the connection can be achieved by using glue, screws and the like, so that the installation is convenient.

[0023] Further, the bottom of the swing piece is provided with a strip-shaped block.

[0024] In this way, the strip-shaped block can make the bottom of the cloth heavier than the top, so that the cloth is prevented from being lifted up, and the weight of the strip-shaped block can be selected according to actual use. BRIEF DESCRIPTION OF DRAWINGS
