Technical Field

The utility model relates to a powder filling machine, in particular to a high-precision powder quantitative automatic filling machine.

Background

In the process of conveying the powder, the powder needs to be quantitatively treated. In the prior art, manual quantitative treatment operation is adopted, so that in powder conveying, especially for powder with large demand, the manual quantitative treatment has high labor intensity, poor quantitative consistency and low quantitative treatment efficiency, seriously influences the overall rhythm and cannot meet the requirement of sending large-batch powder. In order to solve the problems, a butterfly valve switch is arranged at the bottom of the discharge hopper, the flow speed of the powder is controlled by the opening size of the butterfly valve switch, but in practical application, the opening size of the butterfly valve is not easy to control, the powder is difficult to discharge if the opening size is too small, the flow speed of the powder is too large if the opening size is too large, and the discharge is easy to cause too much, so that a high-precision powder quantitative automatic filling machine is urgently needed.

The object of the utility model is achieved in the following way: the utility model provides a high accuracy powder ration automatic filling machine which characterized in that: the feeding device comprises a blanking box, wherein the lower end of the blanking box is concave inwards to form a discharging cavity, the top of the blanking box is connected with a hopper through a feeding pipe, and the bottom of the feeding pipe penetrates through the blanking box and extends into the discharging cavity; the feeding pipe on be provided with the gate valve, the gate valve is by its switching of electric mechanism drive, feeding pipe lateral wall still install the conveying pipe, install the feeding screw rod in the conveying pipe, the feeding screw rod is by its rotation of ration motor drive, the conveying pipe lower part still be provided with the ration pipe, the ration pipe alternates the unloading case and extends into the ejection of compact intracavity, the conveying pipe switches on with the ration pipe.

The electric mechanism is a driving cylinder.

The feeding pipe is transversely arranged at the upper end of the gate valve.

The quantitative motor is a servo motor or a stepping motor.

The bottom of the blanking box is also provided with a weighing platform, and a box body to be packaged is placed on the weighing platform.

The utility model has the beneficial effects that: 1. simple structure, the cost of manufacture is low, improves market competition. 2. Use butterfly valve control, carry out preliminary filling earlier, promote filling efficiency, reuse the accurate filling of screw rod, guarantee the filling precision. 3. The feeding screw can continuously carry out blanking and filling on the powder in a small quantity, the filling precision is higher, the blanking operation of the powder is accurately controlled, manual operation is not needed in the quantifying process, the labor intensity of people is reduced, and the quantification is consistent and accurate.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a high accuracy powder ration automatic filling machine which characterized in that: the automatic feeding device comprises a feeding box 1, wherein a discharging cavity 11 is formed at the concave lower end of the feeding box 1, the top of the feeding box 1 is connected with a hopper 3 through a feeding pipe 2, and the bottom of the feeding pipe 2 penetrates through the feeding box 1 and extends into the discharging cavity 11; the feeding pipe 2 on be provided with gate valve 4, gate valve 4 is by its switching of electric mechanism drive, feeding pipe 2 lateral wall still install conveying pipe 6, install feeding screw 7 in the conveying pipe 6, feeding screw 7 is driven its rotation by quantitative motor 8, conveying pipe 6 lower part still be provided with ration pipe 9, ration pipe 9 alternates blanking box 1 and extends into out material chamber 11 in, conveying pipe 6 switches on with ration pipe 9.

The electric mechanism is a driving cylinder 5.

The feeding pipe 6 is transversely arranged at the upper end of the gate valve 4.

The quantitative motor 8 is a servo motor or a stepping motor.

The bottom of the blanking box 1 is also provided with a weighing platform 10, and a box body 12 to be packaged is placed on the weighing platform 10.

The working principle is as follows: according to the utility model, the inner part of the lower end of the blanking box is concave to form the discharging cavity, the top of the blanking box is connected with the hopper through the feeding pipe, and the bottom of the feeding pipe penetrates through the blanking box and extends into the discharging cavity. The gate valve is arranged on the feeding pipe and driven to be opened and closed by the motor mechanism, powder enters the feeding pipe through the hopper, the gate valve is opened, and the powder smoothly falls into the feeding pipe to be filled after passing through the feeding pipe.

After the powder is filled to a certain degree, the gate valve is closed, the feeding pipe stops filling, and the quantitative motor is started at the moment. The conveying pipe is installed on the side wall of the feeding pipe, the conveying screw rod is installed in the conveying pipe, after the quantitative motor is started, the conveying screw rod starts to rotate, powder falling onto the conveying screw rod falls into the quantitative pipe on the lower portion of the conveying pipe forwards, the quantitative pipe penetrates through the blanking box and extends into the discharging cavity, the conveying pipe is communicated with the quantitative pipe, the quantitative pipe is used for continuously filling the powder in a small amount, and the powder which can be conveyed by the conveying screw rod at each time is limited in a small amount, so that accurate quantitative filling can be carried out on the powder. Compare with the traditional opening size that utilizes the gate valve in order to reduce the powder velocity of flow, the filling precision of pay-off screw rod is higher, has guaranteed that the unloading operation of powder has all obtained accurate control, and the ration process needn't be operated by the manual work, has reduced people's intensity of labour, and the ration is accurate. Besides, the diameter opening size of the quantitative pipe can be smaller than that of the feeding pipe, and the moving range of powder can be reduced on the premise of reducing the manufacturing cost, so that the powder can be accurately fed.
