Description

Technical Field

[0001] This invention relates to the field of cable processing equipment technology, and specifically to a belt-type take-up machine for processing highly waterproof cables. Background Technology

[0002] In some electronic products used in underwater environments, such as various sensors, the cables connected to these electrical appliances need to be insulated and waterproofed. This is usually achieved by wrapping the outside of the cable with an insulating sheath to improve the waterproof and insulation effect of the underwater cable.

[0003] However, in some applications with strong currents and many underwater impurities, fine sand and sharp objects can cut through the insulation sheath. Once water enters, it will quickly affect the normal use of the entire cable. Therefore, this single waterproof insulation method cannot meet the long-term use requirements of some electrical appliances used in underwater scenarios.

[0004] Therefore, a belt-type take-up machine for processing highly waterproof cables is proposed to solve the problems mentioned above. Summary of the Invention

[0005] Technical problems to be solved In view of the above-mentioned shortcomings of the prior art, the present invention provides a belt-type winding machine for processing highly waterproof cables, which can effectively solve the problems of the single waterproof insulation method and poor waterproof effect of cables in the prior art.

[0006] Technical solution To achieve the above objectives, the present invention provides the following technical solution: This invention provides a belt-type cable take-up machine for processing highly waterproof cables, comprising a machine body and an oil cylinder. The machine body is provided with a rotatable traction wheel, and a transmission belt is provided below the traction wheel. The cable enters from one side of the machine body and is inserted between the traction wheel and the transmission belt. The oil cylinder is located inside the machine body and is sleeved on the outside of the cable. Inside the oil cylinder, from the inside out, there are interconnected annular sponge rings and an oil storage cylinder. The oil storage cylinder is filled with liquid waterproof oil and is in communication with the sponge rings.

[0007] Among them, an oil squeezing block is provided above the upper oil cylinder. The oil squeezing block is hinged above the upper oil cylinder and can intermittently abut against the outer end face of the cable when the cable starts to drive, scraping the waterproof oil accumulated on the outer end face of the cable evenly.

[0008] Furthermore, the machine body includes a drive cylinder, which is located directly above the upper oil cylinder. The oil squeezing block is elastically hinged inside the drive cylinder. The end of the oil squeezing block away from the cable is inclined, and a stop block that can be elastically raised and lowered is provided on one side. The movement path of the stop block intersects with the inclined surface of the oil squeezing block.

[0009] Furthermore, the abutment block has a protruding tooth on the side facing the traction wheel, and the machine body has a rotatable gear. The protruding tooth extends between two teeth of the gear and intermittently abuts against the protruding tooth as the gear rotates. The gear is connected to the traction wheel via a driven wheel.

[0010] Furthermore, a rubber top pad is provided at one end of the upper oil cylinder facing the drive cylinder. The rubber top pad is a cylindrical shape with a bowl-shaped concave opening at the top, and multiple oil drain holes are opened in the middle. The oil drain holes are connected to the sponge ring. The multiple oil drain holes are distributed circumferentially in the middle of the rubber top pad, and the diameter of the oil drain holes gradually decreases towards the middle of the rubber top pad.

[0011] Beneficial effects The technical solution provided by this invention has the following advantages compared with known public technologies: This invention utilizes an oiling cylinder located inside the machine body, which can adhere to the outer side of the cable during cable transmission to apply waterproof oil to the cable, forming a hydrophobic layer between the cable and the insulating sheath, thereby improving the cable's insulation and waterproofing performance. Simultaneously, four rotating oil-squeezing blocks are arranged above the oiling cylinder to evenly spread the oil that has slid down and accumulated due to gravity after the oiling is completed, improving its effectiveness and without affecting the smoothness of the subsequent sheathing process.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] The present invention will be further described below with reference to embodiments.

[0017] Example: Waterproof cables are commonly used in electronic devices in water-rich environments, such as temperature sensors, pressure sensors, and many other sensors that may be used underwater.

[0018] Currently, in the manufacturing process of these electronic devices specifically designed for underwater environments, most devices have waterproof structures added to their outer casings. However, the waterproofing effect of cables is limited to methods such as adding insulating sheaths. The overall waterproofing effect of the cable itself is poor. When used for a long time, if the sheath is damaged by external forces, water will seep into the cable, causing damage.

[0019] Before cable processing, a winding machine is used to straighten the cable, reducing its bending degree. This improves the overall insulation and waterproofing of the cable, and is combined with... Figure 1-11This invention provides a belt-type take-up machine for processing highly waterproof cables. By applying a layer of waterproof oil (liquid waterproof adhesive can also be used) to the outside of the cable, it not only effectively improves the overall insulation of the cable, but also provides a hydrophobic layer between the cable and the insulating sheath, thereby improving the cable's own waterproofness.

[0020] This design mainly includes a machine body 1 and an upper oil cylinder 3. The machine body 1 has a rotatable traction wheel 11. A guide wheel 12 is located on each side of the traction wheel 11. The cable enters from one side of the guide wheel 12, loops around the traction wheel 11, and exits from the other guide wheel 12. A drive belt 2 is located below the traction wheel 11. The drive belt 2 rotates below the traction wheel 11 via three drive wheels 21 arranged in a triangle. The upper middle part of the drive belt 2 is in close contact with the cable looped around the lower end of the traction wheel 11. The traction wheel 11 and one of the drive wheels 21 are each driven by two drive motors. (The specific structure of the take-up machine is known technology and is not described in detail in this example.) In this example, the upper oil cylinder 3 is a hollow cylinder, located inside the machine body 1 and sleeved on the outside of the cable. Before the cable is about to pass through the machine body 1, oil is applied to the outer end inside the upper oil cylinder 3. Inside the upper oil cylinder 3, from the inside out, there are interconnected annular sponge rings 31 and oil reservoirs 32. The oil reservoir 32 is filled with liquid waterproof oil and is connected to the sponge rings 31. When the cable passes through, the sponge rings 31 will press against the outside of the cable, applying a layer of waterproof oil to the outside of the cable. An oil supply pipe is connected to one side of the oil reservoir 32 to replenish the oil in the oil reservoir 32 (the waterproof oil used in this example is a common and well-known choice, and the specific principle will not be described in detail here).

[0021] Because some oily residue remains on the outer end of the cable during processing, the waterproofing oil's cohesion is not particularly strong, resulting in accumulation and dripping in practice. Usually, the oil is manually spread out, but this is time-consuming and labor-intensive, and requires constant monitoring of the accumulated areas. Therefore, in this solution, to achieve the best waterproofing oil coating effect, a drive cylinder 4 is specially set at the upper end of the oiling cylinder 3. The four annularly distributed oil squeezing blocks 33 inside the drive cylinder 4 intermittently rub the oiled cable outer end wall against the oil, and the accumulated points are periodically coated downwards on the cable outer wall.

[0022] Specifically, the drive cylinder 4 is equipped with a sliding ring 41 that can slide up and down, and a stop block 34 is connected to the bottom of the sliding ring 41. The stop block 34 moves simultaneously with the up and down movement of the sliding ring 41. In this scheme, four oil squeezing blocks 33 are provided, and they are all elastically hinged in the drive cylinder 4. The cable will pass through the four oil squeezing blocks 33 upwards. When the sliding ring 41 moves down, the stop block 34 will simultaneously abut against one end of the four oil squeezing blocks 33, causing each oil squeezing block 33 to rotate at the same time and abut against the end face of the cable. Thus, the oil on the end face of the cable will be evenly spread. The oil squeezing blocks 33 are hinged above the upper oil cylinder 3 and can intermittently abut against the outer end face of the cable when the cable starts to drive, scraping evenly the waterproof oil accumulated on the outer end face of the cable.

[0023] In this design, the end of the oil squeezing block 33 away from the cable is inclined, and a movable stop block 34 is provided on one side. The moving path of the stop block 34 intersects the inclined surface of the oil squeezing block 33, so that the oil squeezing block 33 can be rotated by the movement of the stop block 34. In this example, a spring 42 is provided between the sliding ring 41 and the drive cylinder 4, so that when the sliding ring 41 is no longer under force, it will return to its original position under the action of the spring force of the spring 42.

[0024] Specifically, a tooth 341 is provided on the side of the sliding ring 41 facing the traction wheel 11, and a rotatable gear 13 is provided on the body 1. The tooth 341 extends into the space between two teeth of the gear 13 and intermittently abuts against the tooth 341 as the gear 13 rotates. The gear 13 is connected to the traction wheel 11 through a driven wheel 131. Teeth are evenly provided on the side wall of the traction wheel 11. When the traction wheel 11 starts to rotate, it will cause the gear 13 to rotate through the driven wheel 131. When the gear 13 rotates, it will abut against the tooth 341. During the travel time of the distance between the two teeth of the gear 13, the entire sliding ring 41 moves down until the tooth abutting against the tooth 341 disengages from the tooth 341. The sliding ring 41 resets and engages with the next tooth of the gear 13.

[0025] Meanwhile, an extrusion block 14 is also provided on the machine body 1 at the outlet of the cable. Two slide rods 141 are inserted on the machine body 1 at the vertical position of the cable, and the extrusion block 14 is sleeved on the two slide rods 141. Each slide rod 141 is fitted with a return spring 142. The return spring 142 abuts against the end of the extrusion block 14 facing the cable. The extrusion block 14 is movably installed on the machine body 1 and can be guided to move in the direction of the cable. The extrusion block 14 is located above the gear 13 and meshes with the gear 13. When the gear 13 starts to rotate, the extrusion block 14 starts to slide guided on the machine body 1.

[0026] In order to ensure that the force of the abutment block 34 against the cable is large enough (that there is sufficient squeezing force when the abutment block 34 abuts against the oil squeezing block 33), the oil squeezing block 33 is rotatably installed in the drive cylinder 4 through a rotating shaft 331, and the distance between the oil squeezing block 33 and its inclined surface from the rotating shaft 331 is greater than the distance between the rotating shaft 331 and its other side, the length of the power arm is increased (the distance between the oil squeezing block 33 and its inclined surface from the rotating shaft 331), so that the force at the contact point with the cable is large enough.

[0027] To prevent the oil squeezed out by the oil squeezing block 33 from dripping everywhere and to allow it to be collected for reuse, a rubber top pad 35 is provided at the end of the upper oil cylinder 3 facing the drive cylinder 4. The rubber top pad 35 is a cylindrical shape with a bowl-shaped concave top, and multiple oil drain holes 342 are opened in the middle. The oil drain holes 342 are connected to the sponge ring 31. The multiple oil drain holes 342 are distributed circumferentially in the middle of the rubber top pad 35, and the diameter of the oil drain holes 342 gradually decreases towards the middle of the rubber top pad 35. Since the thickness of the rubber top pad 35 decreases towards the middle, larger holes are opened in the thicker areas to increase the flow rate and velocity, while the oil drain holes 342 become smaller in the thinner areas to reduce the amount of oil entering. This makes the oil extracted from the entire rubber top pad 35 more uniform and prevents uneven oil distribution on the sponge ring 31.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
