Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, specifically to a rodent- and ant-proof, highly flexible drag chain cable and its preparation method. Background Technology

[0002] Electronic products, as one of the most important parts of modern society in the last century, mostly use electrical energy to convert into mechanical energy or to transmit signals, and their transmission carrier is cable. Cable consists of multiple conductors wrapped in a sheath. When cables are used in laser equipment, machine tools, and mechanical equipment, because such equipment often needs to move back and forth, users often find that conventional cables easily entangle and form knots. These knots not only increase the temperature but also increase the friction between the cable and the equipment, thus affecting the use and maintenance of the equipment. To address this problem, highly flexible drag chain cables have been designed, which can move back and forth with the drag chain without easily tangling.

[0003] Since drag chain cables are mostly used in mechanical equipment, if rodents and ants are not prevented in the production workshop, rodents and ants, especially rats, can easily climb onto the drag chain cables by using the drag chain. Since rats' teeth are constantly growing, they have a habit of grinding their teeth, and the outer sheath of the cable is a perfect grinding board. Therefore, it often happens that rats gnaw through the cable to the conductor layer, and even damage the conductor. Since cables are used to transmit electrical energy, this situation will cause a short circuit. The literature ("Science and Technology Wind", "Discussion on the Safety Work of Rodent Prevention in Indoor Substations", author: He Haifan, 2020, (11): 199) discloses the harm of rodents and insects to cables and electrical equipment. Since mechanical equipment and machine tools often use cooling oil and lubricating oil, when the oil adheres to the outer sheath, it will also corrode the outer sheath, causing the internal conductors to be exposed.

[0004] Based on the above problems, existing technologies have solved the problem of short circuits caused by conductor breakage after cables are chewed by rodents and ants; application number CN201810792786.3 discloses a slow-release rodent and ant-proof cable sheath material; application number CN201610361914.X discloses a rodent-proof data cable; existing technologies have two approaches to rodent and ant prevention. One approach is to cover the cable with metal or fiber armor to prevent rodents and ants from chewing it. However, since drag chain cables often need to move back and forth with the drag chain and have bending performance requirements, the method of covering the cable with metal armor is not suitable. The other approach is to add capsaicin to the cable sheath, which produces a spicy smell that rodents and ants will find repulsive and give up chewing after chewing. Summary of the Invention

[0005] The purpose of this invention is to provide a rodent-proof, highly flexible drag chain cable and its preparation method. By using an oil-absorbing strip fitted outside the inner cable layer to absorb waste cooling oil, the rodents are deterred from gnawing on the inner cable due to the irritating smell of the oil. The oil-absorbing strip, together with the oil-proof sleeve, also prevents machine oil from contacting and corroding the inner cable. The cable is prepared by sequentially fitting the oil-proof sleeve and the oil-absorbing strip outside the cable layer.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rodent- and ant-proof, highly flexible drag chain cable and its preparation method, including...

[0008] A cable for transmitting electrical energy; a cable chain for protecting the cable; cable chain guides fixedly connected to both ends of the cable chain; a cable groove is formed along the central axis of the cable chain; the cable is sleeved in the cable groove.

[0009] The protective components include an oil-proof sleeve and a rodent repellent; the oil-proof sleeve is used to prevent oil corrosion and is fitted over the outside of the cable; the rodent repellent includes a liquid reservoir and a fastening component; the liquid reservoir is used to absorb waste cooling oil to repel rodents; the fastening component is used to securely connect the liquid reservoir to the oil-proof sleeve; the waste cooling oil is waste No. 46 cooling oil.

[0010] The oil-proof sleeve is made of isoprene rubber; the oil-proof sleeve and the cable are tightly fitted together.

[0011] The liquid storage sleeve is fitted over the outside of the oil-proof sleeve and is arranged parallel to the oil-proof sleeve.

[0012] The liquid storage sleeve consists of rag strips and a sponge; the rag strips are made of polypropylene meltblown nonwoven fabric; and the sponge is made of oil-absorbing PU sponge.

[0013] The rag strips are wrapped around the outside of the sponge.

[0014] The fastening component has a ring structure; the fastening component is sleeved on the outside of the liquid storage sleeve; multiple fastening components are arranged in an array along the length direction of the liquid storage sleeve; one fastening component is arranged at every 200-250mm.

[0015] The fastening component is adhesive tape and / or rubber band; the adhesive tape is VC tape; the rubber band is made of isoprene rubber; the cross-sectional diameter of the fastening component is 1-2 mm.

[0016] The oil-proof sleeve is made of polyethylene plastic; there is a gap between the oil-proof sleeve and the cable; the left and right ends of the oil-proof sleeve are attached to the cable by binding components.

[0017] The binding component is fitted over the oil-proof sleeve; the binding component is an elastic rubber sleeve; the binding component is made of isoprene rubber; the cross-sectional diameter of the binding component is 3-4 mm.

[0018] The method for preparing the rodent-proof and ant-proof high-flexibility drag chain cable includes the following steps:

[0019] S1: Securely fit the oil-proof sleeve onto the outside of the cable;

[0020] S2: Secure the liquid storage sleeve to the outside of the oil-proof sleeve;

[0021] S3: Fit the fastening component onto the outside of the liquid storage sleeve; install one fastening component every 200-250mm.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. In this application, waste cooling oil is sprayed onto the oil reservoir. Since the waste cooling oil contains some metal wires, metal powders and other substances generated during equipment operation, when rodents, especially rats, gnaw on the cable, these metal substances attached to the oil reservoir will stimulate their mouths, preventing them from gnawing on the cable. Moreover, because the cooling oil has a pungent odor, rodents will not approach the cable. Furthermore, the waste cooling oil can not only absorb the heat generated by the cable and prevent high temperatures, but also act as a lubricating layer between the cable and the cable chain, preventing wear on the cable after prolonged use.

[0024] 2. The oil-proof sleeve in this application separates the inner cable layer from the outside, ensuring the internal sealing performance; thus preventing oil from contacting the inner cable layer; at the same time, it can also prevent the external cable chain from damaging the internal cable and causing the conductor to be exposed, thereby improving the service life of the cable.

[0025] 3. When the cable is bent, the oil-proof sleeve in this application will deform at the bending point to ensure a tight seal against the cable; and after the cable is no longer bent, it can also quickly recover its deformation to ensure a tight seal against the cable.

[0035] Please see Figures 1 to 8 This invention provides a rodent- and ant-proof, highly flexible drag chain cable and its preparation method, the technical solution of which is as follows:

[0036] Specific Implementation Example 1: This example is applicable to cable 1 with a diameter of 15-40mm;

[0037] A rodent- and ant-proof, highly flexible drag chain cable, comprising:

[0038] Cable 1, used for transmitting electrical energy; cable chain 5, used for protecting cable 1; cable chain guide plates 51 are fixedly connected to both ends of cable chain 5; cable groove 52 is formed along the central axis of cable chain 5; cable 1 is sleeved in cable groove 52; protective components include oil-proof sleeve 2 and rodent repellent; oil-proof sleeve 2 is used to prevent oil corrosion and is sleeved on the outside of cable 1; rodent repellent includes liquid storage sleeve 3 and fastening component 4; liquid storage sleeve 3 is used to absorb waste cooling oil to repel rodents; liquid storage sleeve 3 is used to absorb waste cooling oil; fastening component 4 is used to fix liquid storage sleeve 3 to oil-proof sleeve 2; waste cooling oil... The oil used is waste No. 46 cooling oil; rodents, ants, and other insects often hide in the shadows, which are also where cables are often laid; and because rodents have gnawing teeth, they often use cables as chew sticks; therefore, cables are often damaged by rodents and ants, leading to short circuits; especially since machine tools and laser equipment often use drag chain cables, rodents and ants can climb up the fixed tracks and gnaw on them; furthermore, machine tools often use machine oil, and if machine oil comes into contact with cable 1, it can easily corrode the outer shell of cable 1, causing the internal wires to be exposed; operators may accidentally come into contact with this, thus posing a great safety hazard.

[0039] If rodents and ants are not driven away, they will often gnaw on cable 1 due to their need to gnaw, exposing the wires. Operators may accidentally come into contact with the internal wires, creating a safety hazard. The oil-proof sleeve 2 separates the oil from the cable 1, preventing the oil from corroding the cable 1 and improving the cable's safety performance and service life. The liquid storage sleeve 3 can dissipate the pungent odor of waste cooling oil, keeping rats, insects, and especially termites away from cable 1. The oil can only come into contact with the oil-proof sleeve 2, which separates the oil from the cable 1. Rodent-proof cables often use armor, but due to the requirement for small bending radii in drag chain cables, fiber-based armor is not suitable for rodent-proof drag chain cables. The fastening component 4 fixes the liquid storage sleeve 3 to the oil-proof sleeve 2 and sprays waste cooling oil onto the liquid storage sleeve 3, allowing its odor to be slowly released into the air through the liquid storage sleeve 3.

[0040] Because waste cooling oil contains metal wires and powder generated during equipment operation, these metal substances adhering to the oil reservoir will irritate the mouths of rodents, especially rats, when they gnaw on the cables, preventing them from gnawing on the cables. Furthermore, the pungent odor of the cooling oil will deter rodents and ants from approaching the cables. Waste cooling oil not only absorbs heat generated by the cables, preventing overheating, but also acts as a lubricant between the cable and the cable chain, preventing wear and tear on the cables after prolonged use. Since waste cooling oil is difficult to evaporate in the air, it has a longer service life compared to adding minty substances to the outer sheath. It also absorbs splashed cooling oil during cable operation, further extending the replacement cycle. Using waste cooling oil also represents waste utilization and reduces production costs.

[0041] The oil-proof sleeve 2 is made of isoprene rubber; the oil-proof sleeve 2 and the cable 1 are tightly fitted together; the oil-proof sleeve 2 needs to separate the inner cable 1 from the outside to ensure the internal sealing performance; thus preventing oil from contacting the inner cable 1 layer; the rubber material has deformation recovery ability and can have a certain deformation space, which can improve the sealing effect of the cable; therefore, when the cable bends, the oil-proof sleeve 2 deforms at the bending part to ensure the sealing of the cable; and after the cable is no longer bent, it can also quickly deform and recover to ensure the sealing of the cable.

[0042] The liquid storage sleeve (3) is fitted outside the oil-proof sleeve (2) and is arranged in parallel with the oil-proof sleeve (2). Since the liquid storage sleeve 3 is arranged parallel to the cable 1 and is sealed and fitted with the cable 1 by the fastening component 4, it can also serve as the outermost protective layer of the cable when the drag chain cable is stretched, thus preventing the external drag chain from damaging the internal cable 1 and causing the cable to be exposed, thereby improving the service life of the cable.

[0043] The liquid storage sleeve 3 consists of rags and a sponge; the rags are made of polypropylene meltblown nonwoven fabric; the sponge is made of oil-absorbing PU sponge. The rags and sponge can utilize discarded rags or sponges, effectively reducing cable production costs. Since the liquid storage sleeve 3 needs to absorb and evaporate waste cooling oil, it requires a material with high oil absorption and slow evaporation. Furthermore, it needs to be made of a material with high wear resistance while meeting these conditions. The polypropylene meltblown nonwoven fabric has strong water-locking properties; the oil-absorbing PU sponge has a high oil storage capacity. Waste cooling oil can simply be sprayed onto its surface, improving ease of operation. The rags and sponge absorb the sprayed waste cooling oil and then emit a pungent odor, keeping rats away from the cable.

[0044] The rag strips are wrapped around the outside of the sponge; the oil enters the sponge through the rag strips, and at this time the rag strips can also perform preliminary filtration of the oil to prevent impurities in the oil from clogging the pores of the sponge; the sponge can absorb a large amount of oil, while the rag strips can prevent the oil in the sponge layer from escaping from the oil storage sleeve 3 due to compression; this can both increase the oil absorption capacity of the oil storage sleeve 3 and improve the oil retention of the oil storage sleeve 3.

[0045] The fastening component 4 is a ring structure; the diameter of the fastening component 4 is 15-40mm; the fastening component 4 is sleeved on the outside of the liquid storage sleeve 3; multiple fastening components 4 are arranged in an array along the length of the liquid storage sleeve 3; one fastening component 4 is arranged at every 200-250mm interval; the liquid storage sleeve 3 needs to be attached to the outside of the oil-proof sleeve 2, but due to the bending requirements of the cable, glue or other non-removable fixing connections cannot be used; if the fastening component 4 is not used, the liquid storage sleeve 3 at the bottom will be suspended due to the excessive length of the free end when the cable bends, which will cause the liquid storage sleeve 3 to wrap around the cable chain, causing equipment failure; therefore, the fastening component 4 is used to fix the liquid storage sleeve 3 to the outside of the oil-proof sleeve 2 at intervals of 200-250mm, so that the liquid storage sleeve 3 and the oil-proof sleeve 2 are sealed and attached.

[0046] Fastening component 4 is adhesive tape and / or rubber band; the adhesive tape is VC tape; the rubber band is made of isoprene rubber; the cross-sectional area of ​​fastening component 4 is 1-2 mm²; since the drag chain cable needs to bend, the fastening component 4 located in the middle of the liquid storage sleeve 3 needs to have a certain degree of elasticity; if the fastening component 4 is not elastic, then when the installation part of the fastening component 4 bends, the deformation will cause the diameter of the fastening component 4 to increase, resulting in two situations: one is that the fastening component 4 breaks directly; the other is that the fastening component 4 is forced to increase its diameter, causing the fastening component 4 to no longer be able to seal the liquid storage sleeve 3 and the oil-proof sleeve 2 tightly, thus losing its working performance; when the installation part of the fastening component 4 bends, the adhesive tape uses its adhesiveness to seal the liquid storage sleeve 3 tightly, and the tape also has a certain degree of elasticity to seal and fix the liquid storage sleeve 3 to the oil-proof sleeve 2; the rubber band uses its own elasticity to seal and fix the liquid storage sleeve 3 to the oil-proof sleeve 2.

[0047] The preparation method of rodent- and ant-proof high-flexibility drag chain cable includes the following steps:

[0048] S1: Secure the oil-proof sleeve 2 to the outside of the cable 1;

[0049] S2: Secure the liquid storage sleeve 3 to the outside of the oil-proof sleeve 2;

[0050] S3: Install the fastening component 4 on the outside of the liquid storage sleeve 3; install a fastening component 4 every 200-250mm.

[0051] Specific Embodiment Two: This embodiment is applicable to cable 1 with a diameter of 5-14mm;

[0052] The oil-proof sleeve 2 is made of polyethylene plastic. There is a gap between the oil-proof sleeve 2 and the cable 1. The left and right ends of the oil-proof sleeve 2 are attached to the cable 1 by binding components 21. The oil-proof sleeve 2 needs to separate the inner cable 1 from the outside to ensure the internal sealing performance. This prevents oil from contacting the inner cable 1 layer. Therefore, binding and sealing treatment is required at both ends of the oil-proof sleeve 2. When the cable is bent, the binding components 21 fix the two ends of the oil-proof sleeve 2, so that the oil-proof sleeve 2 is fixed to the outside of the cable 1 layer. The deformation displacement caused by bending is offset by the internal gap, thereby preventing the oil-proof sleeve 2 from slowly slipping off the outer layer of the cable 1 and losing its protective performance after long-term bending movement.

[0053] The binding component 21 is an elastic rubber sleeve; the cross-sectional area of ​​the binding component 21 is 3-4mm; the binding component is made of isoprene rubber; since the drag chain cable needs to bend, the binding components 21 at both ends need to have a certain elasticity; thus, the oil-proof sleeve 2 is sealed and fitted with the cable 1, and cannot enter the gap from both sides to contact the inner layer of the cable 1, improving the working stability of the oil-proof sleeve 2; the tension binding component 21 is fitted onto both ends of the oil-proof sleeve 2, and because it will deform after the tension is lost, the oil-proof sleeve 2 is sealed and fitted with the cable 1.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
