Description

Technical Field

[0001] The present application relates to the field of cable production, and in particular, to a cable oiling and powdering device. Background Art

[0002] Cable oiling and powdering means that during the cable production process, a layer of talcum powder is coated on the core wire. Its main functions are to prevent the cable sheath from adhering to the core wire, making it easy to peel off, and at the same time, it can also improve the insulation performance of the cable and slow down the aging speed of the cable.

[0003] Therefore, it is necessary to pass the cable to be processed through the powdering machine in an orderly manner, and the powdering machine completes the powdering process of the cable. During this process, the cable to be processed enters the interior of the powdering machine through the inlet of the powdering machine. Since the interior of the powdering machine contains raw materials (such as talcum powder), when the cable passes through the powdering machine, the raw materials adhere to the surface of the cable. Subsequently, the cable with the adhered raw materials is removed from the outlet of the powdering machine, completing the powdering process of the cable.

[0004] However, during this process, the raw materials only adhere to the surface of the cable. During the cable transportation process, when the cable is affected by vibration, the raw materials adhered to the surface of the cable will fall off along the surface of the cable, resulting in an unsatisfactory powdering effect. Moreover, the raw materials falling off along the surface of the cable will drop to the production site, affecting the cleanliness of the production site, and there is room for improvement. Utility Model Content

[0005] In order to reduce the amount of raw materials that fall off along the surface of the cable after the cable powdering process is completed, the present application provides a cable oiling and powdering device.

[0006] The cable oiling and powdering device provided by the present application adopts the following technical solutions:

[0007] A cable oiling and powdering device includes a powdering machine. One end of the powdering machine is an inlet, and the other end is an outlet. The powdering machine is used to process the cable. A scraping member is provided at the outlet of the powdering machine. The scraping member is detachably arranged at the outlet of the powdering machine and is used for the cable to pass through and scrape the surface of the cable.

[0008] By adopting the above technical solutions, the cable to be processed enters the powdering machine through the inlet of the powdering machine, and the powdering machine starts to process the cable. After the processing is completed, the cable is sent out through the outlet of the powdering machine. When the cable after the processing is completed reaches the scraping member, the surface of the cable is scraped by the scraping member, so that the raw materials adhered to the surface of the cable are relatively evenly coated on the surface of the cable. At the same time, the scraping member scrapes off some of the excess raw materials adhered to the surface of the cable, which plays a positive guiding role in reducing the amount of raw materials that fall off along the surface of the cable after the cable powdering process.

[0009] Preferably, the scraping member includes a first scraping block and a second scraping block. The second scraping block is disposed at the discharge port of the powdering machine, and the first scraping block is slidably disposed at the discharge port of the powdering machine. When the first scraping block is in contact with the second scraping block, a through hole for the cable to pass through is formed between the first scraping block and the second scraping block, and the diameter of the through hole is larger than the wire diameter of the cable.

[0010] By adopting the above technical solution, when it is necessary to scrape the surface of the cable, the first scraping block can be moved towards the second scraping block until the first scraping block is in contact with the second scraping block, thereby forming a through hole, and the diameter of the through hole is larger than the wire diameter of the cable, so that the cable can smoothly pass through the through hole; when it is not necessary to scrape the surface of the cable, the first scraping block can be separated from the second scraping block, which has high practicability.

[0011] Preferably, a driving member is disposed at the discharge port of the powdering machine, and the driving member is used to drive the first scraping block to approach or move away from the second scraping block.

[0012] By adopting the above technical solution, the driving member is used to drive the first scraping block to act, and there is no need to manually adjust the position of the first scraping block.

[0013] Preferably, the through hole formed between the first scraping block and the second scraping block is provided with a chamfered corner.

[0014] By adopting the above technical solution, the probability of damage to the cable surface caused by the non-smooth edge of the through hole when the cable passes through the through hole, or the probability of the cable being unable to smoothly pass through the through hole is reduced.

[0015] Preferably, a material placing box is disposed on the powdering machine below the first scraping block and the second scraping block, and the material placing box is used to accommodate the raw materials falling off the cable surface.

[0016] By adopting the above technical solution, when the cable passes through the through hole, some of the raw materials scraped off through the through hole will fall into the material placing box, and the material placing box is used to collect the fallen raw materials, which plays a positive guiding role in improving the cleanliness of the production site environment.

[0017] Preferably, guiding members are respectively disposed at the discharge port and the feed port of the powdering machine. The guiding members include a first guiding roller and a second guiding roller. Mounting plates are respectively disposed at the discharge port and the feed port of the powdering machine. The first guiding roller and the second guiding roller are rotatably carried on the mounting plate in the vertical direction, and a gap for the cable to pass through is formed between the first guiding roller and the second guiding roller.

[0018] By adopting the above technical solution, the transmission path of the cable is defined by the first guide roller and the second guide roller, reducing the yaw of the cable during the process from the feeding end of the powder passing machine to the discharging end of the powder passing machine, and improving the stability of the cable when passing through the powder passing machine.

[0019] Preferably, the mounting plate is provided with a waist-shaped groove along its length direction.

[0020] By adopting the above technical solution, the distance between the first guide roller and the second guide roller can be adjusted through the waist-shaped groove, meeting the limiting requirements for cables with different wire diameters. The mechanical structure is simple and has strong applicability.

[0021] Preferably, the scraping member is a scraping member made of Teflon material.

[0022] By adopting the above technical solution, the Teflon material itself has the characteristics of heat resistance and low friction coefficient, which is beneficial to reducing the friction force suffered by the cable and / or the scraping member itself when the cable passes through the scraping member, thereby reducing the probability of the cable being scratched by the scraping member. At the same time, it is also beneficial to extend the maintenance period and service life of the scraping member and reduce the number of replacements of the scraping member.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The surface of the cable is scraped by the scraping member, so that the raw materials adhered to the surface of the cable are relatively evenly coated on the surface of the cable. At the same time, the scraping member scrapes off some of the redundant raw materials adhered to the surface of the cable, which plays a positive guiding role in reducing the amount of raw materials that fall off along the surface of the cable after powder passing treatment.

[0025] 2. When it is necessary to scrape the surface of the cable, the first scraping block can be moved towards the second scraping block to form a threading hole; when it is not necessary to scrape the surface of the cable, the first scraping block can be separated from the second scraping block, which has high practicability.

[0026] 3. The Teflon material itself has the characteristics of heat resistance and low friction coefficient, which is beneficial to reducing the friction force suffered by the cable and / or the scraping member itself when the cable passes through the scraping member.

Detailed implementation manners

[0030] The following further elaborates on this application in conjunction with the attached Figure 1-2 drawings.

[0031] An embodiment of this application discloses a device for passing oil and powder through a cable. Refer to Figure 1 and Figure 2 , a device for passing oil and powder through a cable includes a powder passing machine 1. One end of the powder passing machine 1 is a feeding port, and the other end is a discharging port. The powder passing machine 1 is used to process the cable. A scraping member 2 is arranged at the discharging port of the powder passing machine 1. The scraping member 2 is detachably arranged at the discharging port of the powder passing machine 1. The scraping member 2 is used for the cable to pass through and scrape the surface of the cable.

[0032] Specifically, the powder passing machine 1 is used to coat a layer of raw material (such as talcum powder) on the surface of the core wire of the cable, so as to facilitate the separation of the core wire of the cable from the protective shell, reduce (or lower) the adhesion between the protective shell and the core wire of the cable. It is an existing powder passing device, and its specific composition and working principle will not be elaborated too much here.

[0033] Correspondingly, the scraping member 2 is set as a scraping member made of Teflon material. The Teflon material has the characteristics of heat resistance and low friction coefficient, which is beneficial to reducing the friction force received by the cable and / or the scraping member 2 itself when the cable passes through the scraping member 2, thereby reducing the probability of the cable being scratched by the scraping member 2. At the same time, it is also beneficial to extend the maintenance period and service life of the scraping member 2 and reduce the replacement frequency of the scraping member 2.

[0034] Therefore, the implementation principle of a device for passing oil and powder through a cable in an embodiment of this application is as follows: The cable to be processed enters the powder passing machine 1 along the feeding port of the powder passing machine 1. The powder passing machine 1 starts to process the cable. The processed cable is sent out along the discharging port of the powder passing machine 1. When the processed cable reaches the scraping member 2, the surface of the cable is scraped by the scraping member 2, so that the raw material adhered to the surface of the cable is relatively evenly coated on the surface of the cable. At the same time, the excess raw material adhered to the surface of the cable is scraped off by the scraping member 2, which plays a positive guiding role in reducing the amount of raw material that falls off along the surface of the cable after the cable powder passing treatment.

[0035] Refer to Figure 1 and Figure 2, the scraping member 2 includes a first scraping block 21 and a second scraping block 22. The second scraping block 22 is disposed at the discharge port of the powdering machine 1, and the first scraping block 21 is slidably disposed at the discharge port of the powdering machine 1. When the first scraping block 21 is in contact with the second scraping block 22, a through hole 3 for the cable to pass through is formed between the first scraping block 21 and the second scraping block 22, and the diameter of the through hole 3 is larger than the wire diameter of the cable.

[0036] Specifically, a mounting seat 9 is installed at the discharge port of the powdering machine 1. The mounting seat 9 is located below the discharge port of the powdering machine 1. The second scraping block 22 includes a scraping portion and a base. The outer contours of the scraping portion and the base are arranged in a rectangular parallelepiped shape, and the positional relationship between the scraping portion and the base is perpendicular, and the scraping portion and the base are integrally formed, reducing the probability of the scraping portion breaking or deforming along the base. The base is fixedly connected to the mounting seat 9 by bolts in the vertical direction, so that the second scraping block 22 is stably installed on the mounting seat 9, and at the same time, it is also convenient to replace the second scraping block 22 with different sizes by removing the bolts.

[0037] Correspondingly, the outer contour of the second scraping block 22 is the same as the outer contour of the first scraping block 21. Arc grooves are formed at one ends of the second scraping block 22 and the first scraping block 21 that are in contact with each other. When the first scraping block 21 is in contact with the second scraping block 22, the arc groove on the first scraping block 21 and the arc groove on the second scraping block 22 are mutually combined to form a through hole 3 for scraping the surface of the cable in sequence.

[0038] At the same time, the through hole 3 formed between the first scraping block 21 and the second scraping block 22 is provided with a chamfered corner, reducing the probability that when the cable passes through the through hole 3, the cable surface is damaged due to the non-smooth edge of the through hole 3, or the probability that the cable cannot smoothly pass through the through hole 3.

[0039] Therefore, when it is necessary to scrape the surface of the cable, the first scraping block 21 can be moved towards the second scraping block 22 until the first scraping block 21 is in contact with the second scraping block 22, thereby forming a through hole 3, and the diameter of the through hole 3 is larger than the wire diameter of the cable, so that the cable can smoothly pass through the through hole 3; when it is not necessary to scrape the surface of the cable, the first scraping block 21 can be separated from the second scraping block 22, which has high practicability.

[0040] Refer to Figure 1 and Figure 2 , a driving member 4 is disposed at the discharge port of the powdering machine 1. The driving member 4 is used to drive the first scraping block 21 to approach or move away from the second scraping block 22.

[0041] Specifically, the driving member 4 can be a motor screw driving mechanism. In this embodiment, since the stroke distance between the first scraping block 21 and the second scraping block 22 is fixed, in order to reduce the cost of the driving member 4, the driving member 4 is set as a driving cylinder 41. The driving cylinder 41 is horizontally installed on the mounting seat 9, and the piston rod of the driving cylinder 41 faces the second scraping block 22. The first scraping block 21 is fixedly connected to the piston rod of the driving cylinder 41 through bolts, so that the driving cylinder 41 can stably drive the first scraping block 21 to move towards the first scraping block 21, or drive the first scraping block 21 away from the second scraping block 22, without the need for manual adjustment of the position of the first scraping block 21. The mechanical structure is simple and easy to maintain.

[0042] Referring to Figure 1 and Figure 2 , a material placing box 5 is arranged on the powder feeder 1 located below the first scraping block 21 and the second scraping block 22. The material placing box 5 is used to accommodate the raw materials falling off along the surface of the cable.

[0043] Specifically, the external contour of the material placing box 5 is arranged in a cuboid shape. The material placing box 5 is recessed in the thickness direction to form a receiving groove for containing raw materials. At the same time, the material placing box 5 is not fixedly placed on the mounting seat 9, so as to quickly remove the material placing box 5 along the mounting seat 9, or place the material placing box 5 on the mounting seat 9. When the material placing box 5 is placed on the mounting seat 9, the receiving groove of the material placing box 5 is located directly below the first scraping block 21 and the second scraping block 22, so that the raw materials falling through the through hole 3 can fall into the material placing box 5 with relatively accurate positions, reducing the scattered raw materials at the production site and playing a positive guiding role in improving the cleanliness of the production site environment.

[0044] Referring to Figure 1 and Figure 2 , guiding members 6 are respectively arranged at the discharge port and the feed port of the powder feeder 1. The guiding member 6 includes a first guiding roller 61 and a second guiding roller 62. Mounting plates 7 are respectively arranged at the discharge port and the feed port of the powder feeder 1. The first guiding roller 61 and the second guiding roller 62 are rotatably carried on the mounting plate 7 in the vertical direction, and a gap for the cable to pass through is formed between the first guiding roller 61 and the second guiding roller 62.

[0045] Specifically, since guiding members 6 are respectively arranged at the discharge port and the feed port of the powder feeder 1, and the installation methods and components of the guiding members 6 are the same. The difference is that the mounting plate 7 at the feed port of the powder feeder 1 is fixedly connected to the powder feeder 1, while the mounting plate 7 at the discharge port of the powder feeder 1 is fixedly connected to one end of the mounting seat 9 away from the powder feeder 1.

[0046] Its function is to define the transmission path of the cable through the first guide roller 61 and the second guide roller 62, reduce the yaw of the cable during the process from the feeding end of the powder passing machine 1 to the discharging end of the powder passing machine 1, and improve the stability of the cable when passing through the powder passing machine 1.

[0047] Meanwhile, a waist-shaped groove 8 is formed in the mounting plate 7 along the length direction. Through the waist-shaped groove 8, the distance between the first guide roller 61 and the second guide roller 62 can be adjusted to meet the limiting requirements for cables with different wire diameters. The mechanical structure is simple and has strong applicability.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
