Description

[Technical Field]

[0001] This invention relates to the technical field of water separators, and in particular to the technical field of continuous surface water separators. [Background Technology]

[0002] Cable is a type of wire used to transmit and distribute electrical energy. It typically consists of one or more insulated cores (each of which may be individually covered by an inner sheath) and an outer sheath covering each insulated core. It can be used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater power transmission lines across rivers and seas.

[0003] In existing cable production processes, extrusion and water cooling are generally required. If the cable is not dehydrated after water cooling, the water adhering to the surface can negatively impact subsequent processing, such as causing blurred printing. Therefore, most factories currently use drying to remove water. However, drying requires heating air, consuming significant amounts of electricity and increasing production costs. Furthermore, excessively high temperatures can cause the outer and inner sheaths to shrink and deform, while insufficient temperatures fail to remove water effectively. In contrast, patent CN111696731B discloses a cable surface dehydration device for cable production lines. This device utilizes two winding mechanisms to connect the cable. As the cable moves in a straight line, a drive mechanism rotates a transmission wheel, causing two levers on the wheel to alternately contact the cable. This deflects the cable off its original trajectory and compresses a spring on the guide wheel mechanism, causing the cable to bounce and shake off surface water. The entire process eliminates the need for drying and consumes less energy. While the shaking method for removing water is energy-efficient, a small amount of moisture can still remain on the cable surface and is difficult to remove completely. An additional drying step is required before printing can proceed directly. [Summary of the Invention]

[0004] The purpose of this invention is to solve the problems in the prior art and propose a continuous surface dewatering device that can simultaneously absorb and scrape water from the cable using cotton strips. It has high overall dewatering efficiency and good dewatering effect. Furthermore, the water squeezing mechanism of the two sets of strip changing machines can intermittently squeeze the cotton strips to drain water, thereby achieving continuous dewatering of the cable.

[0005] To achieve the above objectives, the present invention proposes a continuous surface dehydrator, comprising a guide tube, cotton swabs, a swab changing machine, and a controller. The guide tube has a tube channel and a spiral groove on its outer wall. A notch is provided above the spiral groove to connect the outside to the tube channel. The middle part of the cotton swab is wound around the outside of the guide tube along the spiral groove, and the two ends are respectively in the form of cotton rolls and are wound and unwound by the winding and unwinding mechanism of the swab changing machine. The cotton rolls at both ends of the cotton swab are squeezed by the water squeezing mechanism of the swab changing machine to squeeze out excess water. The controller is electrically connected to two sets of swab changing machines.

[0006] Preferably, the notch is in the form of a spiral groove or a plurality of spaced holes.

[0007] Preferably, the take-up and unwinding mechanism includes a roller support, a winding roller, and a roller motor. The winding roller is rotatably connected to the roller support and is driven to rotate by the roller motor. The dewatering mechanism includes a cylinder and a pressure plate. The pressure plate is installed at the free end of the telescopic rod of the cylinder and can be close to or away from the winding roller.

[0008] Preferably, the guide tube and the two sets of strip changing machine rollers are parallel to each other.

[0009] Preferably, the pressure plate is in the shape of an arc plate.

[0010] Preferably, the roll changing machine further includes an adjustment mechanism, wherein the winding and unwinding mechanism and the dewatering mechanism are driven by the adjustment mechanism to move together linearly along the axial direction of the roll.

[0011] Preferably, the adjustment mechanism includes a rod support, a rod motor, a lead screw, a lead screw nut, and a slide rail. The lead screw is rotatably connected to the rod support and is driven to rotate by the rod motor. The slide rail is fixed to the rod support. The lead screw nut is threaded to the lead screw and simultaneously slidably connected to the slide rail. The roller support is fixed to the lead screw nut, and the cylinder is fixed to the roller support.

[0012] Preferably, the system also includes a water tank, which is located below the two sets of strip changing machines and has openings directly opposite the rollers of the two sets of strip changing machines.

[0013] Preferably, the tampon includes a core and an absorbent cotton layer, with the absorbent cotton layer covering the core.

[0014] Preferably, the absorbent cotton layer is also covered with an absorbent woven sleeve.

[0015] The beneficial effects of this invention are:

[0016] 1) By setting up two sets of sliver changers, the two ends of the sliver can be wound and unwound respectively using their winding and unwinding mechanisms. This allows the middle section of the sliver to be simultaneously absorbed and scraped along the moving cable during the winding and unwinding process. The overall water removal efficiency is high and the water removal effect is good. In addition, the water squeezing mechanism of the two sets of sliver changers can also intermittently squeeze the sliver to drain water, so as to achieve continuous water removal of the cable. The guide tube with spiral grooves and notches can guide the sliver without affecting the sliver's operation. The overall structure is simple, easy to maintain, and has low energy consumption and noise.

[0017] 2) The winding and unwinding mechanism is formed by setting up a roller support, a winding roller and a roller motor. The water squeezing mechanism is formed by setting up a cylinder and a pressure plate and installed on the roller support. An adjustment mechanism is added so that the winding and unwinding mechanism and the water squeezing mechanism can move together in a straight line along the axial direction of the winding roller. This does not interfere with the water squeezing mechanism and allows the cotton sliver to be wound or unwound evenly outside the winding roller, ensuring the normal operation of the water removal work.

[0018] 3) By adding a guide core to the absorbent cotton layer, the tensile strength of the tampon can be effectively enhanced, while the absorbent braided sleeve covering the absorbent cotton layer can effectively prevent the surface of the absorbent cotton layer from deforming quickly due to friction, thereby effectively extending the service life of the tampon.

[0019] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0025] Example 1:

[0026] See Figures 1 to 4 The present invention relates to a continuous surface dehydrator, comprising a guide tube 1, a cotton sliver 2, a sliver changing machine 3, and a controller. The guide tube 1 has a tube channel and a spiral groove 11 on its outer wall. The spiral groove 11 has a notch that connects to the outside and the tube channel. The middle part of the cotton sliver 2 is wound around the outside of the guide tube 1 along the spiral groove 11, and the two ends are respectively in the shape of cotton rolls and are wound and unwound by the winding and unwinding mechanism 32 of the sliver changing machine 3. The cotton rolls at both ends of the cotton sliver 2 are squeezed by the water squeezing mechanism 33 of the sliver changing machine 3 to squeeze out excess water. The controller is electrically connected to two sets of sliver changing machines 3.

[0027] The notch is in the shape of a spiral groove.

[0028] The take-up and unwinding mechanism 32 includes a roller support 321, a winding roller 322, and a roller motor 323. The winding roller 322 is rotatably connected to the roller support 321 and is driven to rotate by the roller motor 323. The dewatering mechanism 33 includes a cylinder 331 and a pressure plate 332. The pressure plate 332 is installed at the free end of the telescopic rod of the cylinder 331 and can be close to or away from the winding roller 322.

[0029] The guide tube 1 and the two sets of strip changing machines 3 have their rollers 322 parallel to each other.

[0030] The pressure plate 332 is in the shape of an arc plate.

[0031] The strip changing machine 3 also includes an adjustment mechanism 31, and the winding and unwinding mechanism 32 and the dewatering mechanism 33 are driven by the adjustment mechanism 31 to move together linearly along the axial direction of the winding roller 322.

[0032] The adjustment mechanism 31 includes a rod support 311, a rod motor 312, a lead screw 313, a lead screw nut 314, and a slide rail 315. The lead screw 313 is rotatably connected to the rod support 311 and is driven to rotate by the rod motor 312. The slide rail 315 is fixed to the rod support 311. The lead screw nut 314 is threaded to the lead screw 313 and is slidably connected to the slide rail 315. The roller support 321 is fixed to the lead screw nut 314, and the cylinder 331 is fixed to the roller support 321.

[0033] It also includes a water tank 4, which is located below the two sets of strip changing machines 3 and has openings at the rollers 322 of the two sets of strip changing machines 3.

[0034] The cotton swab 2 includes a core 21 and an absorbent cotton layer 22, with the absorbent cotton layer 22 covering the core 21. The core 21 can be made of a fine rope woven from tough fibers such as aramid, nylon, or polyester, while the absorbent cotton layer 22 can be made of a sponge with good water absorption or cotton fibers with good hydrophilicity.

[0035] The absorbent cotton layer 22 is further covered by an absorbent braided sleeve 23. The absorbent braided sleeve 23 may be made of cotton yarn.

[0036] Working process of this invention:

[0037] Taking an example where the winding rollers 322 of the wire guide drum 1 and the two sets of sliver changers 3 are all horizontal, and the cable 5 to be processed passes horizontally through the drum channel of the wire guide drum 1 and moves from left to right. First, the roller motor 323 of the sliver changer 3 on the left side drives its connected winding roller 322 to rotate in the opposite direction to recover the cotton sliver 2, and the roller motor 323 of the sliver changer 3 on the right side drives its connected winding roller 322 to rotate in the forward direction to release the cotton sliver 2. During this process, the middle part of the cotton sliver 2 moves to the left along the spiral groove 11 outside the wire guide drum 1, thereby scraping the surface of the cable 5 to remove water through the spiral groove notch, and also directly absorbing the moisture on the surface of the cable 5. In addition, the cylinder 331 of the sliver changer 3 on the left side extends or retracts intermittently, thereby causing the pressure plate 332 connected to it to move closer or further away from the winding roller 332 and squeeze the cotton roll multiple times, forcing the water to fall off the cotton roll and temporarily store it in the water tank 4 through the opening. After the left-side changing machine 3 completes its winding operation and the right-side changing machine 3 completes its unwinding operation, the two machines switch roles, allowing the left-side changing machine 3 to unwind while the right-side changing machine 3 performs its winding operation. At this time, the dewatering mechanism 33 of the left-side changing machine 3 stops working, while the dewatering mechanism 33 of the right-side changing machine 3 starts working intermittently.

[0038] For the adjustment mechanism 31 of the two sets of sliver changing machines 3, its rod motor 312 can drive the lead screw 313 to rotate, so that the nut 314 moves horizontally along the lead screw 313 and the slide rail 315, thereby driving the take-up and unwinding mechanism 32 and the squeezing mechanism 33 to move horizontally synchronously, thereby ensuring that the sliver 2 can be evenly wound around the outside of the winding roller 322 or evenly released from the winding roller 322 when the inlet and outlet positions of the sliver 2 of the wire tube 1 remain unchanged.

[0039] Example 2:

[0040] The notch is in the form of several spaced holes.

[0041] Everything else is the same as in Example 1.

[0042] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
