Description

Technical Field

[0001] The invention relates to the technical field of cable processing, and in particular to a pickling device for cable processing. Background Art

[0002] Cable is a general term for optical cables, electrical cables and other items. Cables have many uses, mainly controlling installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. In the process of cable processing, the cables need to be pickled to ensure the quality of the cables after processing. However, the existing cable pickling equipment still has the following problems: Most of the existing cable pickling equipment passes the cable through a hydrochloric acid solution, allowing the hydrochloric acid to react with the oxide layer on the cable surface, and then polishes the cable surface to remove the oxide layer and impurities on the cable surface. Since the cable is in a state of continuous transportation and the hydrochloric acid is continuously consumed and the concentration becomes lower, the subsequent cable pickling effect is poor, and the oxide layer located close to the cable cannot be corroded, resulting in poor cable pickling effect. At the same time, since the cable cannot rotate in the conveying state, using two parallel polishing rollers for polishing may cause the oxide layer in other uncontacted positions of the cable to be unable to be removed, affecting the treatment effect of the cable. Therefore, how to reasonably solve this problem is what we need to consider. Summary of the invention

[0020] Among them, a control block is provided on the rear side of the vertical plate 2, and an adjusting chamber 32 is provided in the control block. A moving block 34 is provided in the adjusting chamber 32. The moving block 34 is slidably connected to the inner wall of the adjusting chamber 32.

The top space of the vertical chamber is connected to the outside through an air inlet pipe, and the top space of the vertical chamber is connected to the bottom space of the adjusting chamber 32 through an air outlet pipe 31. Both the air inlet pipe and the air outlet pipe 31 are provided with a one-way valve, and the outside gas enters the top space of the vertical chamber in one direction through the air inlet pipe. The gas in the bottom space of the vertical cavity enters the bottom space of the regulating cavity 32 in one direction through the air outlet pipe 31. The bottom space of the regulating cavity 32 is connected with the outside through the exhaust port 33. The exhaust port 33 is provided with a solenoid valve. After the solenoid valve is energized, the exhaust port 33 is in a conducting state. The diameter of the exhaust port 33 is twice that of the air outlet pipe 31. Therefore, when the cable moves from right to left, although gas will enter the bottom space of the regulating cavity 32, the exhaust speed of the exhaust port 33 is faster, so that the moving block 34 can move downward by its own gravity.

[0021] The functional principle of the present invention can be explained through the following operation mode: when pickling the cable, at this time, both ends of the cable can be fixedly connected with traction wires, and then the cable is wound on the winding roller 3 located on the left side, and then one of the traction ropes is sequentially passed through multiple threading holes on the pickling box 5 and the polishing box 8, and at this time, the two drive motors 18 can be started; Since the two first conductors 15 at the bottom are in contact with the plurality of second conductors in the initial state, the two driving motors 18 drive the two first rotating rods 4 and the winding roller 3 to rotate clockwise, and the cables are transported from left to right. During the rotation of the first rotating rod 4 on the left side, the cam 20 is driven to rotate. Due to the elastic action of the first spring 17, the piston 21 and the cam 20 are always in a state of abutment, so that the piston 21 moves up and down. When the piston 21 moves up, the space at the bottom of the vertical cavity increases, and the air pressure decreases, so that the hydrochloric acid solution enters the space at the bottom of the vertical cavity. When the piston 21 moves down, the space at the bottom of the vertical cavity increases, and the air pressure decreases, and then the hydrochloric acid solution is pressed into the hollow plate 6 and sprayed out through multiple liquid outlets, corroding the oxide layer on the surface of the cable; At the same time, when the cable is being transported, the rotation of the first rotating rod 4 on the left side drives the second rotating rod to rotate through the transmission assembly 19, and then drives the reciprocating screw 10 to rotate through the two bevel gears 12, so that the sliding rod drives the grinding assembly 9 to move left and right, and then the annular grinding block 24 processes the surface of the cable, so as to quickly remove the oxide layer after corrosion; In the process of the sliding rod moving left and right, the two second conductors will continuously contact with multiple conductive components, so that the third spring 29 is in a state of continuous power on and power off. When the third spring 29 is powered on, according to the electromagnetic effect, each coil will generate a magnetic field, and the magnetic fields generated by every two adjacent coils are in opposite directions. Every two adjacent coils will generate mutual attraction, so that the third spring 29 contracts and drives the rectangular block and the rack 30 to move backward. At this time, the annular grinding block 24 is driven to rotate through the tooth edge group. When the third spring 29 is powered off, the rectangular block and the rack 30 are moved back under the elastic action of the third spring 29, so that the tooth edge group drives the annular grinding block 24 to rotate, and then in the process of the annular grinding block 24 moving left and right, it can rotate to grind the surface maintenance layer of the cable, thereby improving the grinding effect of the oxide layer after corrosion on the cable surface; During the up and down movement of 21, the gas in the top space of the vertical cavity will continuously enter the bottom space of the regulating cavity 32, so that the gas in the bottom space of the regulating cavity 32 increases, and the air pressure increases, thereby causing the moving block 34 to move up. When the cable is completely wound from left to right on the winding roller 3 on the right side, the push rod is in contact with the touch delay switch 35, so that the exhaust port 33 and the first spring 17 are energized for a period of time. At this time, the gas will be discharged through the exhaust port 33 under the action of the moving block 34. Since the diameter of the exhaust port 33 is twice that of the air outlet pipe 31, the subsequent operation of the drive motor 18 will also allow the gas to enter the regulating cavity 32 in time, and will not affect the downward movement of the moving block 34. When the first spring 17 is energized, the first spring 17 will be energized and contracted to drive the slider 16 to move downward. At this time, the two first wires 15 located above will contact the corresponding multiple third wires. At this time, the two driving motors 18 will drive the two first rotating rods 4 to rotate counterclockwise, so that the cable moves from right to left, so that the cable is polished again and then enters the pickling box 5 again. At this time, the hydrochloric acid solution can wash away the debris on the cable after grinding, and at the same time, after grinding, the oxide layer inside can be corroded again, further improving the effect of pickling of the cable; When the pickling is completed, the two drive motors 18 can be turned off and the cables can be removed.

[0022] Compared with the prior art, the rotation assembly and the grinding assembly 9 can simultaneously generate lateral friction and tangential friction on the cable, so that the annular grinding block 24 can perform a more complete and uniform grinding process on the cable surface, thereby better removing the oxide layer on the cable surface; By switching the settings of the components, the cable can be polished and pickled twice, so that the hydrochloric acid can contact the inside of the oxide layer on the surface of the cable, thereby better removing the oxide layer on the cable and improving the pickling effect of the cable. Example

[0023] Reference Figure 6-7 The difference between this embodiment and embodiment 1 is that an adjustment groove 37 is provided on the rear side of the adjustment cavity 32, an adjustment plate 38 is provided in the adjustment groove 37, a connecting rod is provided in the adjustment groove 37, the rear side of the connecting rod extends to the outside and is fixedly connected with a pull ring 36, and a scale line is provided on the pull ring 36. According to the indication of the scale on the scale, the backward movement length of the connecting rod can be judged according to the length of the cable, so as to adjust the backward movement distance of the adjustment plate 38. A plurality of card slots 28 are provided at the upper end of the connecting rod, a mounting block is provided on the rear side of the control block, and a latch 13 is provided at the upper end of the mounting block.

[0024] In this embodiment, when pickling, the corresponding scale line is selected according to the length of the cable, so as to judge the length of the pull ring 36 and the connecting rod to be pulled outward. When the pulling is completed, the pin 13 can be pressed downward to fix the connecting rod. At this time, due to the large gravity of the moving block 34, the gas entering the adjustment chamber 32 first presses the adjustment plate 38 to move backward. When the adjustment plate 38 moves backward to the point where it cannot move, the moving block 34 is moved upward, so that the two driving motors 18 drive the two first rotating rods 4 to move clockwise for a longer time, thereby ensuring that the cable can be completely polished and pickled when it is long. It is worth mentioning that since the time for the cable to move from left to right is adjustable, but the time for the cable to move from right to left is a fixed value, when the cable moves from right to left, after the moving block 34 moves back to its original position, it is necessary to manually rotate the winding roller 3 on the left to completely wind the remaining excess cable on the winding roller 3 on the left (or after the moving block 34 moves back to its original position, the controller can be used to control the two drive motors 18 to drive the two first rotating rods 4 to continue to rotate counterclockwise for a period of time).

[0025] Compared with the prior art, by setting the adjustment plate 38, the distance the adjustment plate 38 moves backward can be adjusted by moving the connecting rod, thereby adjusting the time for the cable to move from left to right (and from right to left), so that the equipment can meet the pickling requirements of different cables and improve the applicability of the device.
