Description

Nozzle mechanism for full-automatic milk powder filling machine

Technical field

The utility model relates to the field of milk powder production and processing, in particular to a nozzle mechanism for an automatic milk powder filling machine.

Background technique

Milk powder is made with fresh milk or goat milk as raw materials. It is processed by freezing or heating to remove almost all of the water in the milk, and then adding appropriate vitamins and minerals after drying.

At present, canned milk powder is usually filled with an automatic filling machine for quantitative filling. The automatic filling machine generally includes a lower hopper. A syringe is usually installed at the bottom outlet of the lower hopper to control the feeding of powdered milk powder. When filling, the conveyor belt transports the empty milk powder tank to the bottom of the syringe in turn, and then fills the milk powder in the lower hopper into the milk powder tank through the syringe. This design can achieve the purpose of fully automatic milk powder filling, but the lower end of the syringe Located above the top of the milk powder tank, the height difference is large, and the goat milk powder is light. When the syringe is fed, the milk powder will be sprayed on the conveyor belt and the surface of the milk powder tank, so that the surface of the milk powder tank sticks to the milk powder.

Utility model content

The purpose of the utility model is to provide a spray nozzle mechanism for a full-automatic milk powder filling machine, which solves the large difference in height between the syringe of the existing full-automatic filling machine and the milk powder tank, so that the milk powder is easily sprayed on the conveyor belt and the surrounding surface of the milk powder tank, resulting in The problem of powdered milk sticking on the surface of the powdered milk tank.

The above-mentioned technical purpose of the present invention is achieved through the following technical solutions:

A nozzle mechanism for a full-automatic milk powder filling machine, including a feeding pipe, a lifting pipe, a dust cover and an air cylinder;

The lifting pipe is sleeved on the outer surface of the blanking pipe, a fixing plate is fixed on the blanking pipe, a connecting plate is fixed on the lifting pipe, the air cylinder is fixed on the fixing plate, and the air cylinder Fixed with the connecting plate and used for driving the lifting pipe to move up and down along the feeding pipe;

The dust cover is arranged around the lifting pipe and is slidably fitted up and down with the lifting pipe, and the dust cover is used to cover the top of the milk powder tank.

With the above structure, after the milk powder tank is conveyed directly below the feeding pipe, the cylinder is activated and the lifting pipe moves down. When the lower end of the lifting pipe rises into the milk powder tank and is close to the bottom of the milk powder tank, the milk powder starts to be poured downwards. With the gradual filling of milk powder, the lifting tube is gradually lifted upward under the drive of the cylinder until the milk powder tank is completely filled with milk powder. As an extension of the feeding tube, the lifting tube penetrates deeply into the milk powder tank to realize the process of gradual filling and moving upward, reducing the feeding height, effectively reducing the flying of milk powder and preventing the milk powder from flying outside the milk powder tank. The dust-proof cover is set on the surface of the milk powder tank, which can reduce the milk powder flying out, and solves the large difference in height between the syringe of the existing automatic filling machine and the milk powder tank, so that the milk powder is easily sprayed on the conveyor belt and the surface of the milk powder tank, causing the surface of the milk powder tank to stick. The problem of milk powder.

It is further optimized that: the outer surface of the discharging pipe is provided with a first protruding strip, the inner surface of the lifting pipe is provided with a first chute, the first protruding strip is embedded in the first chute and slidably fits with it .

With the above structure, the lifting tube can smoothly move up and down on the surface of the feeding tube, and the sliding is relatively stable.

It is further optimized that a second sliding groove is provided on the outer surface of the lifting pipe, a second convex strip is fixed on the dust cover, and the second convex strip and the second sliding groove are both vertically arranged, so The second protruding bar is embedded in the second sliding groove and is slidingly fitted up and down;

The lower end of the second chute is located above the bottom surface of the lifting pipe.

With the above structure, when the lifting tube moves down, the dust cover will move down with the lifting tube, so that the dust cover is placed on the top of the milk powder tank to reduce the powder flying out. When the lifting tube moves upward, the dust cover is under its own gravity. Keep the position unchanged under the action of, until the second protruding bar slides to the lower end of the second chute, at this time the dust cover will move to the top of the milk powder tank along with the lifting tube, and the filling is finished. The dust cover can always be placed on the surface of the milk powder tank until the filling is completed, which can effectively reduce the milk powder flying and prevent the milk powder from flying outside the milk powder tank.

It is further optimized as follows: the dust cover includes an inclined part and a horizontal part;

The inclined portion is located in the middle of the dust cover and has a funnel shape, and the horizontal portion is annular and is arranged on the peripheral edge of the inclined portion and is used to support the top surface of the milk powder tank.

By adopting the above structure, the powdered milk flying to the inner surface of the inclined portion can fall back into the powdered milk tank along the inclined portion, which can effectively reduce the flying of powdered milk.

It is further optimized that the horizontal projection of the inclined part is circular and the diameter is not less than the inner diameter of the milk powder tank.

With the above structure, the milk powder flying to the inner surface of the inclined portion can fall back into the milk powder tank along the inclined portion again, and the dustproof effect is good.

It is further optimized that: the feeding tube is located above the milk powder tank, and the length of the lifting tube is greater than the distance between the bottom surface of the feeding tube and the top surface of the milk powder tank.

By adopting the above structure, the lower end of the lifting pipe can be extended into the milk powder tank, the feeding height is reduced, and the milk powder spreads out.

In summary, the present utility model has the following beneficial effects: after the milk powder tank is transferred directly below the feeding pipe, the air cylinder is activated, and the lifting pipe moves downward under the cooperation of the first convex bar and the first chute. When it rises into the powdered milk tank and is close to the bottom of the powdered milk tank, the powdered milk starts to be poured downwards. With the gradual filling of the powdered milk, the lift pipe is gradually lifted upwards under the drive of the cylinder until the powdered milk tank is completely filled with powdered milk. When the lifting tube moves down, the dust cover will move down with the lifting tube, so that the dust cover is placed on the top of the milk powder tank to reduce the powder flying out. When the lifting tube moves upwards gradually, the dust cover is kept under its own gravity. The position remains the same until the second protruding bar slides to the lower end of the second chute. At this time, the dust cover will follow the lifting tube and move to the top of the milk powder tank, and the filling is completed. As an extension of the feeding tube, the lifting tube penetrates into the milk powder tank to realize the process of gradual filling and moving upward, reducing the feeding height, effectively reducing the flying of milk powder and preventing the milk powder from flying outside the milk powder tank. It solves the problem that the height difference between the syringe of the existing automatic filling machine and the milk powder tank is large, so that the milk powder is easily sprayed on the conveyor belt and the surface of the milk powder tank, causing the surface of the milk powder tank to stick to the milk powder.
