Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and more specifically, to a powdering device for a protective layer in the cable stranding process. Background Art

[0002] Electric wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electrical and magnetic energy. In a broad sense, electric wires and cables are also simply referred to as cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as an aggregate composed of the following parts: one or more insulated wire cores, and their respective possible coating layers, total protective layer, and outer protective layer. When processing electric wires and cables, powdering treatment is required. When the cable is in the stranding process, multiple copper cores are wound together to present a "twisted" shape. It is necessary to powder the surface through talcum powder to facilitate the subsequent recycling treatment of the cable. When powdering the protective layer in the cable stranding process, there are small gaps at the winding places of multiple copper wires. Since the number of copper core windings in the cable stranding area is different, the sizes of the gaps on its surface are different. It is impossible to adjust the powdering space accordingly according to the characteristics of the cable protective layer, so that the talcum powder closely adheres to the surface of the cable, avoiding the existence of unpowdered areas at the gaps on the surface of the cable, improving the powdering quality. At the same time, it is also impossible to recycle the excess powder on the surface of the cable after powdering to avoid the scattering of talcum powder. In view of the above technical defects, a solution is provided now. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a powdering device for a protective layer in the cable stranding process.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A powdering device for a protective layer in the cable stranding process, including a support frame and a cover plate fixedly installed on its top. Two limiting grooves are symmetrically opened on the top of the cover plate. An adjusting assembly for adjusting the powdering volume is arranged outside the powdering pool. A recycling assembly for recycling the excess talcum powder on the surface of the cable after powdering is arranged at the output end of the powdering pool. The adjusting assembly includes a cylinder arranged below the support frame, and the output end of the cylinder is fixedly connected to the powdering pool. A lower output member is arranged outside the cylinder; mounting blocks are symmetrically arranged on both sides of the powdering pool, and an upper receiving member is arranged outside the mounting blocks.

[0005] Further, the lower output member includes two groups of limiting tubes symmetrically arranged outside the cylinder, and a piston plate I is slidably arranged inside the limiting tube.

[0006] Further, a first piston rod is fixedly arranged above the first piston plate. The top of the first piston rod movably penetrates above the limit pipe, and the tops of the two first piston rods are fixedly connected to a lifting plate together.

[0007] Further, the lifting plate is fixedly connected to the extending end of the air cylinder, and the output end above the limit pipe is connected to an air outlet pipe.

[0008] Further, the upper receiving member includes a movable cavity opened above the mounting block. A second piston plate is slidably arranged inside the movable cavity, and a second piston rod is fixedly installed at the end of the second piston plate.

[0009] Further, the end of the second piston rod movably penetrates into the powder passing pool. A thrust spring is sleeved on the outer wall of the second piston rod located inside the movable cavity, and the output end of the air outlet pipe is communicated with the movable cavity.

[0010] Further, a U-shaped plate is fixedly arranged at the end of the second piston rod. A pair of limit plates are fixedly installed on the side wall of the U-shaped plate. The limit plates are slidably matched with the mounting block, and the two groups of U-shaped plates are symmetrically arranged.

[0011] Further, two groups of stirring rods are symmetrically arranged inside the powder passing pool. A driving shaft is fixedly arranged inside the stirring rod. The end of the driving shaft extends to the outside of the powder passing pool and is fixedly provided with a motor, and the motor is connected to the powder passing pool.

[0012] Further, the recycling assembly includes a recycling box arranged at the output end of the powder passing pool. The end of one driving shaft extends outside the powder passing pool and is connected to a connecting shaft through a transmission member. A driving gear is fixedly arranged on the outside of the connecting shaft; A driven gear is meshed and connected to the outside of the driving gear. A driven shaft is fixedly connected to the center of the driven gear. The ends of the connecting shaft and the driven shaft are jointly connected to a fixing frame, and the fixing frame is connected to the supporting frame.

[0013] Further, a fan is fixedly connected to the end of the driven shaft. A fan cover is arranged on the outside of the fan, and the fan cover is connected to the fixing frame. The output end of the fan cover is connected to a blowing pipe through a conveying pipe.

[0014] The technical effects and advantages of the present invention: 1. In the present invention, by controlling the extension end of the air cylinder to extend upward, the lifting plate pulls the piston plate one upward, enabling the gas above the piston plate one to enter the interior of the movable cavity through the air outlet pipe. The air pressure inside the movable cavity increases, pushing the piston plate two to one side, causing the piston rod two to push the U-shaped plate to one side. The two U-shaped plates move closer synchronously, cooperating with the powder passing pool to move upward, so that the tops at both ends of the powder passing pool and the tops of the U-shaped plates contact the cover plate, compressing the powder passing space, making the talcum powder closely adhere to the surface of the cable in a twisted shape, avoiding the existence of un-powdered areas at the corners of the cable surface, and improving the powder passing quality.

[0015] 2. In the present invention, the stirring rod continuously stirs the talcum powder inside the powder passing pool, causing the driving shaft to rotate continuously. The rotation of the driving shaft drives the connecting shaft to rotate through the transmission member, and the connecting shaft drives the gear two to rotate through the gear one, realizing the rotation of the driven shaft, and further realizing the rotation of the fan. The wind speed generated by the fan enters the blowing pipe through the conveying pipe, gently blows the surface of the cable after powder passing, blows off the excess talcum powder on it, and recovers the excess talcum powder above it into the interior of the recovery box, avoiding the scattering of talcum powder and saving resources.

[0016] 3. In the present invention, according to the surface characteristics of the cable, the space of the powder passing area is adjusted, so that the talcum powder closely adheres to the surface of the cable, avoiding the existence of un-powdered areas at the corners of the cable surface. At the same time, after powder passing, the excess talcum powder on the cable surface is gently blown, and the excess talcum powder above it is recovered, jointly improving the powder passing quality of the cable.

At the same time, after powder passing, the excess talcum powder on the cable surface is gently blown to recycle the excess talcum powder above it, jointly improving the powder passing quality of the cable.

[0027] Working principle: When the present invention is in use, talcum powder is put into the powder passing tank 8, and the cable after "electrostatic treatment" is passed through the powder passing tank 8 to perform powder passing treatment on the protective layer of the cable; When the surface of the cable is twisted: The extending end of the control cylinder 51 extends upward, the lifting plate 525 pulls the piston rod 523 upward, the piston rod 523 pulls the piston plate 522 upward, so that the gas above the piston plate 522 enters the inside of the movable cavity 531 through the air outlet pipe 524; the air pressure inside the movable cavity 531 increases, pushing the piston plate 52 to one side, so that the piston rod 523 pushes the U-shaped plate 56 to one side, and the two U-shaped plates 56 move closer synchronously, cooperating with the powder passing pool 8 to move upward, so that the tops at both ends of the powder passing pool 8 and the tops of the U-shaped plates 56 contact the cover plate 1, compressing the powder passing space, so that the talcum powder enters the surface of the twisted cable, avoiding the phenomenon that the corners of the cable surface are not coated with talcum powder and improving the powder passing quality; During this process, the stirring rod 7 continuously stirs the talcum powder inside the powder passing pool 8, so that the driving shaft 9 rotates continuously. The rotation of the driving shaft 9 drives the connecting shaft 63 to rotate through the transmission part 62. The connecting shaft 63 drives the gear 2 to rotate through the gear 1, realizing the rotation of the driven shaft 66, and then realizing the rotation of the fan. The wind speed generated by the fan enters the blowing pipe 610 through the conveying pipe 69, gently blows the surface of the cable after powder passing, blows off the excess talcum powder on it, and recovers the excess talcum powder above it into the inside of the recovery box 61, avoiding the scattering of talcum powder.
