Description

Technical Field

[0001] This utility model belongs to the technical field of cable production equipment, specifically relating to a surface drying device after the water cooling process in cable production. Background Technology

[0002] Cable production lines typically involve the extrusion of insulation layers. After extrusion, the insulation layer is at a high temperature and needs to be cooled. The conventional method is to install a water cooling tank after the extrusion process to cool the cable using water.

[0003] In existing technologies, to prevent water stains on the cable surface from affecting subsequent processes, the water stains on the cable surface are removed after it leaves the water-cooling tank. This is typically done by blowing in a high-speed airflow. This method involves multiple nozzles arranged around the outer circumference of the cable, spraying high-speed airflow onto the cable surface through these nozzles. However, given the continuous production process and the inherent high transmission speed of cables, this method cannot guarantee complete removal of water stains when the cable diameter is large and the surface has a significant amount of water. The water stain removal effect is poor, and it also requires pressurization equipment, resulting in high manufacturing costs and poor practicality. Utility Model Content

[0004] This utility model provides a surface drying device after the water cooling process in cable production, which aims to solve the problem of poor practicality of existing water stain cleaning methods applied to cable production.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a surface drying device after the water cooling process in cable production, comprising:

[0006] An open box is positioned behind the water-cooling tank along the direction of cable transmission; the open box has an open slot at the top for the cable to pass through horizontally; the direction of cable transmission is defined as a first direction, and the horizontal direction perpendicular to the first direction is defined as a second direction.

[0007] A water-absorbing structure is provided on the open box and has two water-absorbing parts. The two water-absorbing parts are located on both sides of the cable along the second direction and are in contact with the surface of the cable. The water-absorbing structure is used to remove water stains from the surface of the cable through the two water-absorbing parts.

[0008] A drying structure, disposed on the open box and located behind the water-absorbing structure along the first direction, is used to blow hot air onto the surface of the cable from the water-absorbing part.

[0009] In one possible implementation, the water-absorbing structure includes:

[0010] Two rotating shafts are provided, both of which are rotatably mounted on the open box in a vertical direction, and the two rotating shafts are respectively located on both sides of the cable in the second direction;

[0011] Two rollers are provided, and the two rollers are coaxially connected to two rotating shafts respectively. The outer edge of each roller is covered with an annular sponge layer. Each roller and the corresponding annular sponge layer are combined to form the water-absorbing part.

[0012] A drive component, disposed on the open box, is used to drive the two rotating shafts to rotate in opposite directions.

[0013] In one possible implementation, the thickness of each of the annular sponge layers is greater than the radius of the cable.

[0014] In one possible implementation, the top of the open box is provided with two fixed plates that are rotatably connected to the top ends of the two rotating shafts.

[0015] In one possible implementation, the water-absorbing structure further includes two squeezing components, both of which are located in the open groove and correspond one-to-one with each of the rollers. Each squeezing component is located on the side of the corresponding roller away from the cable and abuts against the annular sponge layer on the outer edge of the corresponding roller, for squeezing the annular sponge layer to remove the water adsorbed in the annular sponge layer.

[0016] In one possible implementation, each of the extrusion components includes:

[0017] A sliding rod is slidably disposed on the open box along the second direction; a transition seat is provided at one end of the sliding rod near the roller;

[0018] The pressure roller is rotatably mounted on the adapter, and the axis of rotation is set along the vertical direction;

[0019] A spring, sleeved on the sliding rod, with one end abutting against the inner wall of the open groove and the other end abutting against the adapter seat, is used to spring the sliding rod so that the sliding rod continuously tends to move toward the roller.

[0020] In one possible implementation, the width of the pressure roller is greater than the width of the annular sponge layer in the vertical direction.

[0021] In one possible implementation, the drying structure includes two hot air blowers, both of which are fixed to the top of the open box and respectively positioned on both sides of the cable along the second direction; each hot air blower has an air outlet facing the cable.

[0022] In one possible implementation, the air outlet is an elongated opening extending in the first direction.

[0023] In this implementation, the open box provides an open slot to ensure that water stains removed by the absorption and drying structures are received, preventing water from dripping onto the bottom surface. The two absorbent parts of the absorption structure contact the cable from both sides, absorbing water stains and achieving pre-removal. The drying structure thoroughly removes any remaining water stains from the cable, drying its surface. This device is suitable for cables with large diameters or significant amounts of surface water stains, offering excellent water stain removal, low cost, and high practicality.

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Please refer to the following: Figure 1 and Figure 2 The present invention describes a surface drying device for cable production after a water-cooling process. The surface drying device for cable production after a water-cooling process includes an open box 10, a water-absorbing structure 20, and a drying structure 30. The open box 10 is positioned behind the water-cooling tank along the transmission direction of the cable 40. The open box 10 has an open groove 11 with an open top for the cable 40 to pass horizontally. The transmission direction of the cable 40 is defined as a first direction, and the horizontal direction perpendicular to the first direction is defined as a second direction. The water-absorbing structure 20 is mounted on the open box 10 and has two water-absorbing parts. The two water-absorbing parts are located on both sides of the cable 40 along the second direction and are in contact with the surface of the cable 40. The water-absorbing structure 20 can remove water stains from the surface of the cable 40 through the two water-absorbing parts. The drying structure 30 is mounted on the open box 10 and is located behind the water-absorbing structure 20 along the first direction. It can blow hot air onto the surface of the cable 40 transmitted by the water-absorbing parts.

[0034] The surface drying device for cable production after the water-cooling process provided in this embodiment, compared with the prior art, provides an open tank 10 with an open slot 11, ensuring that the water stains removed by the water absorption structure 20 and the drying structure 30 are received, preventing water stains from dripping onto the bottom surface. The two absorbent parts provided by the water absorption structure 20 can contact the cable 40 from both sides, thereby absorbing the water stains adhering to the cable 40 and achieving pre-removal of water stains. The drying structure 30 can thoroughly remove the remaining water stains on the cable 40, thereby achieving surface drying of the cable 40. This device can adapt to cables 40 with larger diameters or more surface water stains, providing good water stain cleaning effect, low cost, and strong practicality.

[0035] In some embodiments, the water-absorbing structure 20 described above can be as follows: Figure 2 The structure shown. See also Figure 2 The water-absorbing structure 20 includes a rotating shaft 21, rollers 22, and a driving component 24. Two rotating shafts 21 are provided, each rotatably mounted on the open box 10 along a vertical direction, and positioned on opposite sides of the cable 40 along a second direction. Two rollers 22 are provided, coaxially connected to the two rotating shafts 21, and each roller 22 has an annular sponge layer 23 covering its outer edge. Each roller 22 and its corresponding annular sponge layer 23 combine to form the water-absorbing section. The driving component 24 is mounted on the open box 10 and can drive the two rotating shafts 21 to rotate in opposite directions.

[0036] The rotating shaft 21 ensures the installation of the two rollers 22 and also guarantees the transmission of power from the drive component 24 to the two rollers 22. A channel for the cable to pass through is formed between the two rollers 22, and the annular sponge layer 23 covering the outer edge of the rollers 22 ensures contact with the surface of the cable 40. The sponge material has good water absorption, and the two annular sponge layers 23 can be indented when in contact with and compressed against the surface of the cable 40, thus ensuring complete wrapping of the cable 40. The drive component 24 can drive the two rotating shafts 21 to rotate in opposite directions, that is, one rotating shaft 21 rotates clockwise and the other rotating counterclockwise. This rotation mode can accommodate the transmission of the cable 40. In addition, the way the two rollers 22 drive the two annular sponge layers 23 to rotate ensures rolling contact with the cable 40, avoiding sliding friction between the annular sponge layers 23 and the cable 40, thus effectively protecting the annular sponge layers 23.

[0037] As one embodiment of the driving component 24 in this embodiment, see [link to relevant documentation]. Figure 2 The bottom ends of both rotating shafts 21 can extend out of the open box 10, and a sealed bearing is provided between the open box 10 and the rotating shafts 21. The drive component 24 may include two drive motors, which are respectively connected to the extended ends of the bottom of the two rotating shafts 21.

[0038] As another embodiment of the driving component 24 in this embodiment, see [link to relevant documentation]. Figure 3 The bottom ends of both rotating shafts 21 can extend out of the open box 10, and a sealed bearing is provided between the open box 10 and the rotating shafts 21. The driving component 24 may include a driving shaft 241, a worm gear 243, and a driver 244. The driving shaft 241 is rotatably disposed at the bottom end of the open box 10 along a second direction. The driving shaft 241 is provided with two worm gear portions 242, which correspond one-to-one with the two rotating shafts 21, and the two worm gear portions 242 are arranged in opposite directions of rotation. There are two worm gears 243, which are coaxially connected to the bottom ends of the two rotating shafts 21 respectively, and respectively mesh with the two worm gear portions 242. When the driver 244 drives the driving shaft 241 to rotate, the two worm gear portions 242 can drive the two worm gears 243 to rotate in opposite directions, thereby ensuring that one driver 244 drives two rollers 22 to rotate in opposite directions.

[0039] In some embodiments, the annular sponge layer 23 may be adopted as follows: Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 Each annular sponge layer 23 has a thickness greater than the radius of the cable 40. This structure can further ensure that when the two annular sponge layers 23 are squeezed by the cable 40, they can completely wrap or cover the cable 40, ensuring the water stain absorption effect.

[0040] In some embodiments, the open box 10 described above can be adopted as follows: Figure 1 The structure shown. See also Figure 1 The top of the open box 10 is provided with two fixed plates 12 for the top ends of the two rotating shafts 21 to rotate and connect. The fixed plates 12 can limit the other end of the rotating shaft 21, thereby ensuring the stability of the rotation of the two rollers 22.

[0041] In some embodiments, the water-absorbing structure 20 described above can be as follows: Figure 1 The structure shown. See also Figure 1 The water-absorbing structure 20 also includes two squeezing components 25, each located in the open groove 11 and corresponding to one of the rollers 22. Each squeezing component 25 is located on the side of the corresponding roller 22 away from the cable 40 and abuts against the annular sponge layer 23 on the outer edge of the corresponding roller 22, thereby squeezing the annular sponge layer 23 to remove the water adsorbed inside the annular sponge layer 23.

[0042] When the annular sponge layer 23 absorbs water, the water is difficult to drain out, which may affect the removal of water stains adhering to the surface of the cable 40. In this case, the annular sponge layer 23 can be squeezed by the squeezing component 25 at the end away from the cable 40 to remove the water inside the annular sponge layer 23, thereby ensuring the water absorption effect of the annular sponge layer 23.

[0043] In some embodiments, the extrusion member 25 may be employed as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 Each extrusion component 25 includes a sliding rod 251, a pressure roller 252, and a spring 253. The sliding rod 251 is slidably mounted on the open box 10 along a second direction. An adapter seat 254 is provided at one end of the sliding rod 251 near the roller 22. The pressure roller 252 is rotatably mounted on the adapter seat 254, with its axis of rotation arranged vertically. The spring 253 is sleeved on the sliding rod 251, with one end abutting against the inner wall of the open groove 11 and the other end abutting against the adapter seat 254, and is able to spring the sliding rod 251 so that the sliding rod 251 continuously tends to move towards the roller 22.

[0044] The sliding rod 251 ensures the installation of the pressure roller 252. The sliding rod 251 is slidably set and bounces through the spring 253. The pressure roller 252 can ensure rolling contact with the annular sponge layer 23. At the same time, the spring 253 can prevent the pressure roller 252 from making hard contact with the annular sponge layer 23, thus protecting the annular sponge layer 23 and extending its service life.

[0045] In some embodiments, the pressure roller 252 may be as follows: Figure 2 The structure shown. See also Figure 2In the vertical direction, the width of the pressure roller 252 is greater than the width of the annular sponge layer 23. This structure can ensure that the annular sponge layer 23 is fully squeezed, thereby ensuring the water removal effect.

[0046] In some embodiments, the drying structure 30 described above may employ, for example... Figure 1 The structure shown. See also Figure 1 The drying structure 30 includes two hot air blowers 31, both of which are fixed to the top of the open box 10 and are respectively arranged on both sides of the cable 40 along the second direction. Each hot air blower 31 has an air outlet facing the cable 40.

[0047] The hot air blower 31 can be a household hair dryer, which does not need to be too powerful or deliver too much heat. It only needs to dry the residual moisture on the surface of the cable 40. It is inexpensive to manufacture and highly practical.

[0048] In some embodiments, the above-mentioned air outlet can be adopted as follows: Figure 1 The structure shown. See also Figure 1 The air outlet is a long strip 32 extending in the first direction.

[0049] The elongated opening 32 extends the contact range between the hot air and the cable 40, thereby ensuring the drying effect.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
