It is small in size, provides uniform powdering, is not affected by the dryness of the compressed gas, saves powder, and saves electricity.

The liftable base includes a base plate, a support tube, a support rod, and an adjusting bolt. The support tube is vertically installed on the base plate, and the support rod is vertically installed at the bottom of the outer casing. The support rod is inserted downward into the support tube and can be adjusted up and down within the support tube.

[0009] In the above technical solution, the outer box is a metal outer box with a transparent window, and the inner cylinder is a transparent acrylic inner cylinder.
[0010] The beneficial effects of this utility model are: (1) Since the pneumatic reciprocating motor is installed on one side of the outer box and the power output end of the pneumatic reciprocating motor is connected to the fur friction block to drive the fur friction block to reciprocate, this utility model does not use the expensive static generator to generate static electricity, but uses the reciprocating fur friction block to generate static electricity on the surface of the cable, which is conducive to reducing production costs and the fur friction block is easy to maintain; (2) Since this utility model uses a pneumatic rotary motor and a pneumatic reciprocating motor, the compressed gas pipeline can input compressed gas into the pneumatic rotary motor and the pneumatic reciprocating motor, and control the pneumatic rotary motor and the pneumatic reciprocating motor to work through the compressed gas, this utility model does not use electricity to directly drive the motor, but uses the fur friction block to generate static electricity in the cable, and uses compressed gas to drive the pneumatic rotary motor and the pneumatic reciprocating motor to achieve the purpose of cable powdering; small size, uniform powdering, not affected by the dryness of compressed gas, saving powder and saving electricity.

[0015] like Figure 1 As shown, the operating principle of this utility model is as follows:
[0016] Step 1: During the movement of the plastic-insulated cable 100, the surface of the cable 100 comes into contact with the fur friction block 11 with animal fur. The fur friction block 11 moves back and forth quickly under the drive of the pneumatic reciprocating motor 10, causing the plastic insulation of the cable 100 to become statically charged.
[0017] Step 2: Talc powder is injected through the powder injection cylinder 3 and enters the inner cylinder (2) under the action of the machine's own vibration; the fan (8) rotates under the drive of the pneumatic rotary motor 7, raising the talc dust to the height of the cable 100 passing position, and the cable 100 with static electricity on its surface can be evenly adsorbed with a layer of talc powder.

[0019] like Figure 1 and Figure 2 As shown, the lower end side wall of the inner cylinder 2 connected to the powder feeding cylinder 3 is a porous inner cylinder 2 wall. During the injection process, talc powder is injected through the powder feeding cylinder 3, and under the action of the machine's own vibration, it continuously and in small amounts enters the inner cylinder 2 through the porous inner cylinder wall 4, resulting in a uniform flow of talc powder.

The liftable base 12 includes a base plate 121, a support tube 122, a support rod 123, and an adjusting bolt 124.
