Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a quantitative feeding device for preventing powder spraying. Background Technology

[0002] When the powder is mixed and fed into the powder tank, it is fed quantitatively through a solenoid valve. However, during feeding, the powder tends to accumulate at the funnel-shaped area at the bottom of the powder tank. During a particular feeding, the accumulated powder is very likely to spray or surge.

[0003] In traditional technology, this problem is usually solved by vibration. This method involves adding an air hammer to the funnel tank, which is fixed to the outer wall. When the air hammer works, it strikes the outer wall of the tank and generates vibration. The vibration is transmitted to the powder inside the tank, preventing the powder from accumulating easily, thus achieving the effect of preventing spraying and impact.

[0004] In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been well resolved: However, air hammers are often fixed in one place, and their position cannot be changed. The vibration generated by the air hammer in one place is difficult to transmit to the other end. Even if an air hammer is installed at the other end, the powder in other places will still have the problem of not being able to receive the vibration. If multiple air hammers are used, the cost will increase. The multi-point impact of the air hammer will also cause a certain degree of damage to the tank. If this method is not used, the powder in different places in the powder tank will still accumulate or slightly accumulate. Utility Model Content

[0005] The main purpose of this invention is to provide a quantitative feeding device for preventing powder spraying, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A powder anti-spraying quantitative feeding device includes a powder tank, a funnel-shaped feeding tank below the powder tank, an inner ring outer end block fixed to the outer wall of the middle position of the funnel-shaped feeding tank, an outer ring outer end block sleeved on the outer wall of the inner ring outer end block, an inner annular groove carved in the inner wall of the outer ring outer end block, and a plurality of annular external teeth evenly arranged on the outer wall of the outer ring outer end block. An anti-spraying mechanism is provided at the bottom of the outer ring outer end block. The anti-spraying mechanism includes a base, a motor fixed to one end of the base located outside the outer ring outer end block, a toothed roller fixed to the output end of the motor, a heightening seat fixed to the top of the motor away from the motor, an air hammer fixed to the top of the heightening seat, and brackets fixed to both ends of the top of the base between the motor and the heightening seat. An arc-shaped slider is fixed to the top of the bracket near the toothed roller.

[0008] Preferably, the toothed roller is located outside the outer end block of the outer ring, and the toothed roller is engaged with the annular external teeth on the outer wall of the outer end block of the outer ring.

[0009] Preferably, the arc-shaped slider is located inside the inner annular groove and is slidably connected to it.

[0010] Preferably, the air hammer is located between the inner wall of the outer ring outer end block and the outer wall of the inner ring outer end block, and the output end of the air hammer matches the height of the inner ring outer end block.

[0011] Preferably, a fixing frame is fixed to the top of the outer end block of the outer ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The arc-shaped slider at one end of the bracket slides within the inner annular groove, and the meshing of the toothed roller with the outer annular teeth allows the suppression mechanism to rotate around the outer end block of the outer ring after the motor starts working. The rotation of the base will drive the air hammer on the top of the riser to rotate as well. The rotating air hammer can strike the outer end block of the inner ring on the outer wall of the hopper feed tank. This method can use one air hammer as the striking source and one motor as the power source to strike the hopper feed tank from all directions, eliminating the increased cost and risk of tank damage caused by multiple striking sources. At the same time, it can achieve the effect of multi-point striking, which can suppress the accumulation of powder at the hopper feed tank and has good practicality. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a powder anti-spraying quantitative feeding device includes a powder tank 1, a funnel feeding tank 2 is provided below the powder tank 1, an inner ring outer end block 3 is fixed to the outer wall of the middle position of the funnel feeding tank 2, an outer ring outer end block 4 is sleeved on the outer wall of the inner ring outer end block 3, an inner annular groove 41 is carved on the inner wall of the outer ring outer end block 4, a plurality of annular external teeth 42 are equidistantly arranged on the outer wall of the outer ring outer end block 4, an suppression mechanism 5 is provided at the bottom of the outer ring outer end block 4, the suppression mechanism 5 includes a base 51, a motor 52 is fixed to the top end of the base 51 located outside the outer ring outer end block 4, a toothed roller 53 is fixed to the output end of the motor 52, an elevating seat 54 is fixed to the top of the motor 52 away from the motor 52, an air hammer 55 is fixed to the top of the elevating seat 54, and brackets 56 are fixed to both ends of the top of the base 51 located between the motor 52 and the elevating seat 54, and an arc-shaped slider 57 is fixed to the top end of the bracket 56 near the toothed roller 53.

[0021] Specifically, the toothed roller 53 is located outside the outer end block 4 of the outer ring, and the toothed roller 53 is engaged with the annular external teeth 42 on the outer wall of the outer end block 4 of the outer ring, which facilitates the rotation of the suppression mechanism 5.

[0022] Specifically, the arc-shaped slider 57 is located inside the inner annular groove 41 and is slidably connected to it, providing support to the suppression mechanism 5 and enabling it to slide.

[0023] Specifically, the air hammer 55 is located between the inner wall of the outer end block 4 of the outer ring and the outer wall of the outer end block 3 of the inner ring. The output end of the air hammer 55 is matched with the height of the outer end block 3 of the inner ring. The air hammer 55 can hit the outer end block 3 of the inner ring, thereby transmitting the shock force to the powder in the hopper feed tank 2.

[0024] Specifically, a fixing frame is fixed to the top of the outer ring outer end block 4 to provide support for the outer ring outer end block 4 and the suppression mechanism 5.

[0025] Working principle:

[0026] The arc-shaped slider 57 at one end of the bracket 56 slides within the inner annular groove 41. The meshing of the toothed roller 53 and the outer annular tooth 42 causes the suppressing mechanism 5 to rotate around the outer end block 4 of the outer ring after the motor 52 is working. The rotation of the base 51 will drive the air hammer 55 on the top of the raising seat 54 to rotate together. The rotating air hammer 55 can strike the outer end block 3 of the inner ring on the outer wall of the funnel feed tank 2. This method can use one air hammer 55 as the striking source and one motor 52 as the power source to strike the funnel feed tank 2 from all directions. It does not require the increased cost and increased risk of tank damage caused by multiple striking sources. At the same time, it can achieve the effect of multi-point striking and can suppress the accumulation of powder at the funnel feed tank 2, which has good practicality.
