[0027] An arc-shaped plate 2 is slidably connected to the inside of the powder receiving box 1, and two sliding rods 204 are connected to the inside of the powder receiving box 1. A connecting block 205 is slidably connected to each sliding rod 204, and each connecting block 205 is respectively connected to both sides of the arc-shaped plate 2. A driving mechanism for pushing the arc-shaped plate 2 to rise and fall is installed on the powder receiving box 1; by providing a driving mechanism, the arc-shaped plate 2 can move back and forth inside the powder receiving box 1, and the arc-shaped plate 2 drives the talcum powder collected on its surface to move back and forth, so that the bottom end of the wires and cables can be continuously powdered, thereby improving the uniformity of the powdering of the wires and cables.
[0028] In a preferred embodiment, the driving mechanism includes a first motor 201 , a rotating rod 202 , a cam 203 and a return spring 206 ;
[0029] A first motor 201 is installed on the outer wall of the pollen receiving box 1, and a rotating rod 202 is sleeved on the output end of the first motor 201. The rotating rod 202 is rotatably connected to the inside of the pollen receiving box 1. A cam 203 is connected to the rotating rod 202, and the outer wall of the cam 203 is attached to the bottom end of the arc plate 2. A return spring 206 is connected to each sliding rod 204, and the other end of each return spring 206 is connected to the bottom end of the connecting block 205.
[0030] In a preferred embodiment, a triangular plate 4 is connected to the inside of the pollen receiving box 1, and two material guide ports are opened inside the pollen receiving box 1. The outer walls of the two material guide ports are connected together and a loading bin 401 is installed. The loading bin 401 is connected to the outer wall of the pollen receiving box 1, and a loading mechanism is provided inside the loading bin 401.
[0031] In a preferred embodiment, the feeding mechanism includes a second motor 402 and an auger 403;
[0032] A second motor 402 is installed on the top of the feeding bin 401, and an auger 403 is sleeved on the output end of the second motor 402. The bottom end of the auger 403 is rotatably connected to the inside of the feeding bin 401; by providing a feeding mechanism, the talcum powder collected inside the powder receiving box 1 can be reused to avoid waste of talcum powder.
[0033] In a preferred embodiment, two limiting grooves 301 are provided inside the powder receiving box 1 , and the guide plates 3 are rotatably connected inside the two limiting grooves 301 . The outer wall of the powder receiving box 1 is provided with a movable mechanism for driving the guide plates 3 to reset.
[0034] In a preferred embodiment, the movable mechanism includes a connecting rod 302, a baffle 303 and a torsion spring 304;
[0035] The outer wall of each guide plate 3 is connected to a connecting rod 302, and the outer wall of the powder receiving box 1 is connected to a baffle 303. The ends of the two connecting rods 302 are rotatably connected to the baffle 303. The outer wall of each connecting rod 302 is connected to a torsion spring 304, and the other end of each torsion spring 304 is connected to the baffle 303. By providing a movable mechanism, when there is no talcum powder extruded on the surface of the guide plate 3, under the action of the torsion spring 304, the connecting rod 302 will drive the guide plate 3 to quickly return to its original position, thereby reducing the splashing and overflow of talcum powder.
[0036] In a preferred embodiment, the inner walls of the two wire and cable inlets and outlets 102 are connected to a brush ring 5; by providing the brush ring 5, the surface of the wire and cable can be cleaned when the wire and cable enter the powder receiving box 1, and when the wire and cable leave the powder receiving box 1, the excess talcum powder can be scraped off, thereby improving the uniformity of the talcum powder on the surface of the wire and cable.
[0037] Working principle: The wires and cables enter the powder receiving box 1 through the wire and cable inlet and outlet 102, and the wires and cables are pulled out of the powder receiving box 1 at a uniform speed through the traction device. The powder discharging device intermittently spreads talcum powder on the inside of the powder receiving box 1 at the powder outlet 101, and the guide plate 3 is squeezed by the weight of the talcum powder, so that the guide plate 3 rotates inside the limit groove 301, so that the talcum powder falls between the two guide plates 3 to the surface of the wires and cables. When there is no talcum powder squeezing the surface of the guide plate 3, under the action of the torsion spring 304, the connecting rod 302 will drive the guide plate 3 to quickly return to its original position, The talcum powder can be reduced from splashing and overflowing, and the excess talcum powder will slide along the surface of the wires and cables and fall onto the surface of the curved plate 2. By driving the first motor 201 to drive the rotating rod 202 to rotate, the cam 203 is rotated and the curved plate 2 is continuously lifted, so that the curved plate 2 drives the connecting block 205 to slide on the slide rod 204. Under the action of the return spring 206, the curved plate 2 can rebound quickly, so that the curved plate 2 drives the talcum powder collected on its surface to move back and forth, so that the bottom end of the wires and cables can be continuously powdered, thereby improving the uniformity of the powdering of the wires and cables.
[0038] The curved plate 2 drives the talcum powder to vibrate continuously, and some of the talcum powder will separate from the surface of the curved plate 2 due to the vibration and fall onto the triangular plate 4. The talcum powder moves on the surface of the triangular plate 4 and enters the loading bin 401. The second motor 402 drives the auger 403 to rotate, thereby driving the talcum powder entering the loading bin 401 to move upward until it enters the powder receiving box 1, and then moves on the surface of the guide plate 3 and slides to the surface of the wire and cable for powdering.
[0039] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
