[0002] In the production process of PET film products, there is a requirement for adding flame retardant powder to raw materials. Since most flame retardant powders have extremely small particle sizes, during traditional manual feeding, dust is extremely likely to occur and is easily inhaled into the human body, which harms human health and causes environmental pollution.

[0003] Currently, most powder feeding is done manually. The finer the powder, the easier it is to generate dust, and the dust will exist in the working environment for a long time, which has a great harm to the environment and the health of personnel. At present, there are some automatic feeding devices, but they are not ideal in terms of controlling dust-free and feeding accuracy. Therefore, to solve the above problems, we provide a precise dust-free powder adding device. Summary of the Invention

The telescopic end of the electric push rod is fixedly connected with a connecting plate. The front surface of the connecting plate is fixedly connected with the outer surface of the pneumatic rotary valve.

[0007] Preferably, the upper surface of the moving bottom plate is fixedly connected with a sliding seat. The outer surface of the sliding seat is provided with a sliding groove. The outer surface of the sliding seat is fixedly connected with a moving push handle.

[0008] Preferably, a sliding block is slidably connected inside the sliding groove. The front surface of the sliding block is fixedly connected with the back surface of the connecting plate.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution for an accurate dust-free powder adding device:

[0023] An accurate dust-free powder adding device includes a moving bottom plate 1. A mechanism box 2 is fixedly installed on the upper surface of the moving bottom plate 1. A vacuum pump 3 is fixedly installed on the upper surface of the mechanism box 2. An air suction pipe 4 is fixedly connected to the input end of the vacuum pump 3. A vacuum storage tank 5 is arranged above the moving bottom plate 1. A small reverse blow type bag dust collector 6 is fixedly installed on the upper surface of the vacuum storage tank 5. The top end of the vacuum storage tank 5 is fixedly connected to the top end of the air suction pipe 4. A pneumatic rotary valve 7 is fixedly installed at the bottom end of the vacuum storage tank 5. A feeding hose 8 is fixedly connected to the outer surface of the vacuum storage tank 5. An electric push rod 14 is fixedly installed on the upper surface of the moving bottom plate 1. The electric push rod 14 is a power-driven device that converts the rotational motion of a motor into the linear reciprocating motion of a push rod, and can be used as an actuator in various simple or complex technological processes to achieve remote control, centralized control or automatic control. The electric push rod 14 consists of a driving motor, reduction gears, a screw rod, a nut, a guide sleeve, a push rod, a spring, a housing, a turbine, a micro motion control switch, etc. The telescopic end of the electric push rod 14 is fixedly connected to a connecting plate 13. The front surface of the connecting plate 13 is fixedly connected to the outer surface of the pneumatic rotary valve 7. Through the arrangement of the electric push rod 14 and the connecting plate 13, the pneumatic rotary valve 7 and the vacuum storage tank 5 can be flexibly moved up and down, thereby facilitating the adjustment of the height of the vacuum storage tank 5 and making the powder adding and feeding more flexible and convenient.

[0024] In this embodiment, a sliding seat 10 is fixedly connected to the upper surface of the moving bottom plate 1. A sliding groove 11 is formed on the outer surface of the sliding seat 10.

The front surface of the sliding block 12 is fixedly connected to the back surface of the connecting plate 13. Specifically, through the arrangement of the sliding seat 10 and the sliding groove 11 and the cooperation with the sliding block 12, the vacuum storage tank 5 can be stably lifted and lowered. With the arrangement of the moving push handle 16, it will be more convenient to move the device.

[0025] In this embodiment, two sets of universal wheels 19 are fixedly installed on the bottom surface of the movable bottom plate 1. Both sets of universal wheels 19 are equipped with self-locking braking structures. A flexible connection outlet joint 15 is fixedly installed at the bottom end of the pneumatic rotary valve 7.
