Description

Technical Field

[0001] The present invention relates to the technical field of cable production, and in particular to a cable surface treatment device for cable production. Background Art

[0002] Cable oiling refers to applying a layer of protective oil on the cable surface through specific equipment and methods during the cable production process to enhance the protection performance of the cable and extend its service life. The protective oil layer can prevent the cable surface from being eroded by the external environment, reduce friction and wear, and at the same time provide certain insulation and waterproof functions.

[0003] In the prior art, after the cable oiling is completed, the remaining oil needs to be recovered. Manual recovery is mostly used, or an integrated scraping part or an oil absorption block is used to remove the remaining oil on the cable surface. However, the scraping effect of the remaining oil scraping part is not good. During the oil absorption process when the oil absorption block contacts the cable, it also closely adheres to the cable surface for absorption. However, during the absorption process, the oil on the upper half surface of the cable will continuously flow downward due to gravity. Therefore, after the cable passes through the oil absorption block, the remaining oil between multiple cores in the cable will continue to flow downward, resulting in the secondary downward flow and residue of the remaining oil at the position of the lower half surface of the cable, leading to incomplete recovery of the remaining oil and affecting the subsequent drying of the cable. Summary of the Invention

[0004] The present invention provides a cable surface treatment device for cable production, which solves the problem that in the prior art, the remaining oil flows downward for the second time and remains at the position of the lower half surface of the cable, resulting in incomplete recovery of the remaining oil and affecting the subsequent drying of the cable.

[0005] The technical solution of the present invention is as follows:

[0006] A cable surface treatment device for cable production includes an oiling cabin. Two openings are respectively provided on two side walls of the oiling cabin, namely a cable inlet and an outlet. Two conveyor wheel groups are symmetrically arranged inside the oiling cabin, and the two conveyor wheel groups are respectively located at the positions of the two openings;

[0007] It further includes a remaining oil collection mechanism. The remaining oil collection mechanism includes a recovery cabin. The recovery cabin is installed at the cable outlet position of the oiling cabin. A drying cabin is installed at the outlet position of the recovery cabin. An upper oil absorption block and a lower oil absorption block are arranged inside the recovery cabin. The upper oil absorption block and the lower oil absorption block are arranged horizontally. Both the upper oil absorption block and the lower oil absorption block are U-shaped. The opening of the upper oil absorption block faces downward, and the opening of the lower oil absorption block faces upward.

[0008] Furthermore, an installation cover is provided at the top of the recovery cabin. The top of the upper oil absorption block is installed on the lower side of the installation cover through a first mounting plate. The two sides of the top of the lower oil absorption block are installed on the lower side of the installation cover through two second mounting plates.

[0009] Further, permeation and drainage components are connected to the bottoms of the upper oil absorption block and the lower oil absorption block respectively.

[0010] Further, the permeation and drainage components are a first oil seepage block and a second oil seepage block. Two of the first oil seepage blocks are respectively connected to two ends of the bottom of the upper oil absorption block, and one second oil seepage block is connected to the bottom of the lower oil absorption block.

[0011] Further, the top width of the first oil seepage block is greater than the width of the upper oil absorption block, and the top width of the second oil seepage block is greater than the width of the lower oil absorption block. The widths of the first oil seepage block and the second oil seepage block gradually decrease from top to bottom, and the bottoms of the first oil seepage block and the second oil seepage block are pointed ends.

[0012] Further, the residual oil collection mechanism further includes a lifting component and an extrusion component. The lifting component is installed in the recovery cabin, and the extrusion component is installed at the lifting end of the lifting component.

[0013] Further, the extrusion component includes side plates, a second strip plate, a mounting seat, swing rods, telescopic driving parts and connecting rings. There are two side plates, and the two side plates are symmetrically fixed on the inner side walls of both sides of the recovery cabin. The two side plates are respectively located on both sides of the two first oil seepage blocks. The second strip plate is installed at the lifting end of the lifting component, and the mounting seat is installed on the top of the second strip plate. There are two swing rods, and the middle parts of the two swing rods are respectively rotatably connected to the upper ends of both sides of the second strip plate through rotating shafts. Four telescopic driving parts are symmetrically installed on both sides of the mounting seat in pairs. A connecting ring is installed at the telescopic end of each telescopic driving part. Two connecting rings are movably sleeved on each swing rod. The two connecting rings on each swing rod are located on both sides of the rotating shaft on the swing rod. One first extrusion strip is rotatably installed at one end of each swing rod close to the first oil seepage block through a torsion spring rotating shaft seat, and one second extrusion strip is rotatably installed at one end of each swing rod close to the second oil seepage block through a torsion spring rotating shaft seat.

[0014] Further, the lifting component includes a first strip plate and a lifting driving part. The first strip plate is fixed in the recovery cabin. There are two lifting driving parts, and the two lifting driving parts are installed on the first strip plate. The second strip plate is installed at the lifting ends of the two lifting driving parts.

[0015] Further, the bottom edges of the cable inlet and outlet on the oil passing cabin are both higher than the oil liquid level in the cabin.

[0016] Further, a drying channel is arranged in the drying cabin, and the drying channel is communicated with the outlet of the recovery cabin.

[0017] The beneficial effects of the present invention are as follows: It realizes the absorption of the oil on the upper surface of the cable first, and then the absorption of the oil on the lower surface, achieving a step-by-step treatment of the residual oil recovery. Because during the cable transmission process, the oil on the upper part will flow downward due to gravity. Therefore, absorbing the oil on the upper surface first can prevent the oil on the upper part from flowing downward, and then absorbing the oil on the lower part realizes the step-by-step treatment of the oil on the upper and lower parts, avoiding secondary residue caused by the downward flow of the oil on the upper part.

[0030] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] As Figure 1-8 shown, this embodiment proposes a cable surface treatment device for cable production, including an oil passing tank 1. Two openings are respectively provided on the two side walls of the oil passing tank 1, which are respectively a cable inlet and an outlet. Two conveyor wheel groups are symmetrically arranged inside the oil passing tank 1, and the two conveyor wheel groups are respectively located at the positions of the two openings; there are two conveyor wheels 2 in each conveyor wheel group, and the cable passes through the middle of the two conveyor wheels 2 and is conveyed.

[0033] The bottom edge heights of the cable inlet and outlet on the oil passing tank 1 are both higher than the oil liquid level inside its tank.

[0034] It also includes an oil residue collection mechanism. The oil residue collection mechanism includes an oil recovery tank 3. The oil recovery tank 3 is installed at the cable outlet position of the oil passing tank 1. A drying chamber 21 is installed at the outlet position of the oil recovery tank 3. An upper oil suction block 6 and a lower oil suction block 10 are arranged inside the oil recovery tank 3. The upper oil suction block 6 and the lower oil suction block 10 are horizontally arranged. Both the upper oil suction block 6 and the lower oil suction block 10 are U-shaped. The opening of the upper oil suction block 6 faces downward, and the opening of the lower oil suction block 10 faces upward.

[0035] An installation cover 4 is arranged on the top of the oil recovery tank 3. The top of the upper oil suction block 6 is installed on the lower side of the installation cover 4 through a first mounting plate 5. The two sides of the top of the lower oil suction block 10 are installed on the lower side of the installation cover 4 through two second mounting plates 9.

[0036] In this embodiment, when using the cable surface treatment equipment for cable production, the cable to be treated is inserted through the cable inlet, transmitted through two transmission wheels 2 and then enters the oil tank 1, and then exits through the two transmission wheels 2 at the outlet. A sufficient amount of oil is added into the oil tank 1 so that the cable in the oil tank 1 can be submerged, and thus the cable undergoes an oil passing treatment.

[0037] After the oil passing is completed, the cable is transmitted and leaves from the cable outlet and enters the recovery tank 3. A large amount of remaining oil will be carried on the cable surface. For efficient recovery, the cable after the oil passing process passes below the upper oil suction block 6 and then above the lower oil suction block 10, so that the upper oil suction block 6 abuts against the upper half surface of the cable, and the lower oil suction block 10 fits against the lower half surface of the cable. Both the upper oil suction block 6 and the lower oil suction block 10 are U-shaped. Therefore, the upper oil suction block 6 will first absorb the oil on the upper half surface of the cable. After the absorption of the oil on the upper half surface is completed, it passes through the lower oil suction block 10, and the lower oil suction block 10 will absorb the oil on the lower half surface. Thus, the oil on the upper half surface of the cable is absorbed first, and then the oil on the lower half surface is absorbed, realizing the step-by-step treatment of the remaining oil recovery. Because during the cable transmission process, the oil on the upper part will flow downward due to gravity. Therefore, by first absorbing the oil on the upper half surface, the oil on the upper part is prevented from flowing downward, and then the oil on the lower half surface is absorbed, realizing the step-by-step treatment of the oil on the upper and lower parts and avoiding the secondary residue caused by the downward flow of the oil on the upper part.

[0038] First, the upper half part is subjected to oil suction, and then the lower half part is subjected to oil suction, forming a sequential step-by-step treatment. During the process of absorbing the remaining oil on the upper half part, the remaining oil in multiple wire cores in the cable will flow downward to the position of the lower half surface of the cable, and then the remaining oil on the lower half surface is absorbed, achieving a sufficient absorption effect, leaving time for the remaining oil in the wire cores to flow downward, and avoiding the re-outflow of the remaining oil between the wire cores after wiping.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, as Figure 1-8 shown, both the bottom of the upper oil suction block 6 and the bottom of the lower oil suction block 10 are connected with a penetration and drainage assembly.

[0041] In this embodiment, during the process of using the upper oil suction block 6 and the lower oil suction block 10 to collect the remaining oil, in order to prevent the excessive amount of oil absorbed in the upper oil suction block 6 and the lower oil suction block 10 from not being discharged in time, resulting in the excessive oil leaching onto the cable surface again, a penetration and drainage assembly is proposed to divert the remaining oil in the upper oil suction block 6 and the lower oil suction block 10 downward.

[0042] The penetration and drainage assembly is the first oil seepage block 7 and the second oil seepage block 11. Two first oil seepage blocks 7 are respectively connected to both ends of the bottom of the upper oil suction block 6, and one second oil seepage block 11 is connected to the bottom of the lower oil suction block 10.

[0043] The top width of the first oil seepage block 7 is greater than the width of the upper oil absorption block 6, the top width of the second oil seepage block 11 is greater than the width of the lower oil absorption block 10, the widths of the first oil seepage block 7 and the second oil seepage block 11 gradually decrease from top to bottom, and the bottoms of the first oil seepage block 7 and the second oil seepage block 11 are pointed.

[0044] When the upper oil absorption block 6 and the lower oil absorption block 10 absorb a lot of excess oil, the excess oil penetrates downward and enters the first oil seepage block 7 and the second oil seepage block 11. The upper oil absorption block 6 and the lower oil absorption block 10 can be oil absorption sponges or other oil absorption materials, and the first oil seepage block 7 and the second oil seepage block 11 are materials with better oil absorption and permeability.

[0045] The first oil seepage block 7 and the second oil seepage block 11 are triangular in shape as a whole, and the width of the upper end is large, which can completely receive the oil seeping out from the bottom of the upper oil absorption block 6 and the lower oil absorption block 10. In order to improve the efficiency of the downward seepage of the residual oil in the first oil seepage block 7 and the second oil seepage block 11, the width gradually decreases from top to bottom and gradually becomes a pointed end. As a result, the oil on the upper side gradually converges to the middle during the downward flow. Since gravity will continue to converge downward, the amount of oil per unit volume at the lower tip position of the first oil seepage block 7 and the second oil seepage block 11 will increase rapidly in a short period of time, and finally drip down from the tip, and the residual oil is stored in the recovery cabin 3. Thus, the absorbed residual oil is avoided from being stored in the upper oil absorption block 6, the lower oil absorption block 10, the first oil seepage block 7 and the second oil seepage block 11 for a long time, and the excessive absorption of residual oil is avoided from leaching onto the cable for a second time.

[0046] Example 3

[0047] On the basis of Example 2, Figure 1-10 As shown, the residual oil collection mechanism also includes a lifting component and an extrusion component. The lifting component is installed in the recovery cabin 3, and the extrusion component is installed at the lifting end of the lifting component.

[0048] In order to further improve the efficiency of the residual oil flowing downward, an extrusion component is proposed in this embodiment, which can further accelerate the extrusion of the oil in the first oil seepage block 7 and the second oil seepage block 11, and accelerate the efficiency of the absorbed residual oil flowing out from the bottom of the first oil seepage block 7 and the second oil seepage block 11, thereby further improving the efficiency of residual oil recovery.

[0049] The extrusion assembly includes side plates 8, second strip plates 14, mounting seats 15, swing rods 16, telescopic driving members 17 and connecting rings 18. There are two side plates 8, and the two side plates 8 are symmetrically fixed on the inner side walls of both sides of the recovery cabin 3. The two side plates 8 are respectively located on both sides of the two first oil seepage blocks 7. The second strip plate 14 is installed at the lifting end of the lifting assembly. The mounting seat 15 is installed on the top of the second strip plate 14. There are two swing rods 16. The middle parts of the two swing rods 16 are respectively rotatably connected to the upper ends of both sides of the second strip plate 14 through rotating shafts. Four telescopic driving members 17 are symmetrically installed in pairs on both sides of the mounting seat 15. A connecting ring 18 is installed at the telescopic end of each telescopic driving member 17. Two connecting rings 18 are movably sleeved on each swing rod 16. The two connecting rings 18 on each swing rod 16 are located on both sides of the rotating shaft on this swing rod 16. One first extrusion strip 19 is rotatably installed at one end of each swing rod 16 close to the first oil seepage block 7 through a torsion spring rotating shaft seat. One second extrusion strip 20 is rotatably installed at one end of each swing rod 16 close to the second oil seepage block 11 through a torsion spring rotating shaft seat.

[0050] Among them, the two first extrusion strips 19 are located between the two first oil seepage blocks 7, and the two second extrusion strips 20 are located on both sides of the second oil seepage block 11.

[0051] The lifting assembly includes a first strip plate 12 and a lifting driving member 13. The first strip plate 12 is fixed in the recovery cabin 3. There are two lifting driving members 13, and the two lifting driving members 13 are installed on the first strip plate 12. The second strip plate 14 is installed at the lifting ends of the two lifting driving members 13.

[0052] A drying channel 22 is provided in the drying cabin 21, and the drying channel 22 is communicated with the outlet of the recovery cabin 3.

[0053] In this embodiment, after the remaining oil enters the first oil seepage block 7 and the second oil seepage block 11, it gradually converges downward to the tip and then drips downward. To speed up the process, an extrusion assembly is used. The two telescopic drive members 17 close to the first extrusion bar 19 extend, and the two telescopic drive members 17 close to the second extrusion bar 20 contract. Then, the two swing rods 16 swing, driving the two first extrusion bars 19 to move away from each other. The two first extrusion bars 19 tightly abut against the two first oil seepage blocks 7, and the other side of the first oil seepage block 7 is abutted by the side plate 8. At the same time, the two second extrusion bars 20 move closer to each other, clamping the second oil seepage block 11 in the middle. Subsequently, the lifting drive member 13 drives the second strip plate 14 to move downward, driving the first extrusion bar 19 and the second extrusion bar 20 to move downward. The two second extrusion bars 20 move downward while pressing the second oil seepage block 11, thereby extruding the remaining oil in the second oil seepage block 11 downward. Then, the remaining oil quickly moves downward in the second oil seepage block 11 and drips down from the tip at the bottom of the second oil seepage block 11. Similarly, the first extrusion bar 19 and the side plate 8 also squeeze the first oil seepage block 7 to move downward, and the remaining oil quickly moves downward in the first oil seepage block 7 and flows out downward, realizing the rapid collection of the absorbed remaining oil. In actual use, an extrusion cycle is set, and the remaining oil is extruded once every cycle, avoiding the long-term retention of the remaining oil in the upper oil absorption block 6, the lower oil absorption block 10, the first oil seepage block 7, and the second oil seepage block 11, improving the efficiency of the remaining oil recovery and greatly improving the effect of the remaining oil recovery.

[0054] After the remaining oil recovery is completed, the cable enters the drying channel 22 of the drying chamber 21 for drying, and the oil-passing operation of the cable can be completed.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
