Description

Technical Field

[0001] This invention belongs to the field of cable production technology, specifically a cable asphalt spraying device. Background Technology

[0002] Currently, in the production process of power cables, in order to improve the performance of the cables, it is necessary to add an asphalt spraying layer during the processing of the cable insulation layer.

[0003] In existing technologies, when spraying asphalt onto cable surfaces, powdered asphalt is mostly sprayed out using atomizing nozzles. The sprayed asphalt powder acts on the cable surface. To ensure that the asphalt powder acts on the cable surface over the largest possible area, the spraying range of the atomizing nozzle needs to be increased. However, when the spraying range of the asphalt powder is increased, some asphalt powder may not act on the cable surface and may escape. The escaped asphalt powder disperses in the surrounding production environment, which will pollute the production environment and be detrimental to the physical and mental health of the workers. In addition, there is a significant waste of asphalt powder, thereby increasing the production cost of the cable. Summary of the Invention

Therefore, they should not be construed as limitations on this invention.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Please see Figure 1 , Figure 2 as well as Figure 3This embodiment provides a cable asphalt spraying device, including a supporting base plate 10, a cable reel 20, a spraying assembly 30, a driving assembly 40, a collecting assembly 50, and a scraping assembly 60. A set of first support plates 101 are fixedly installed at the left and right ends of the upper part of the supporting base plate 10, with the two sets of first support plates 101 distributed opposite each other. A set of cable reels 20 is rotatably installed on one side of each set of first support plates 101. The spraying assembly 30 is located at the middle position of the upper part of the supporting base plate 10 and is used to spray asphalt powder onto the cable surface. The driving assembly... The component 40 is provided in two sets. The two sets of drive components 40 are respectively installed on the side walls of the two sets of first support plates 101, and are used to drive the two sets of coils 20 to rotate respectively. The collection component 50 extends partly to the inside of the spraying component 30 and the other part extends to the outside of the spraying component 30. When the spraying component 30 sprays asphalt powder onto the cable surface, the collection component 50 is used to collect excess asphalt powder. The scraper component 60 is disposed on the upper part of the support base plate 10 and is used to scrape off the asphalt powder collected by the collection component 50.

[0046] For ease of understanding, one set of reels 20 is referred to as the pay-off reel, and the other set is referred to as the take-up reel. The cable to be coated with asphalt powder is wound on the pay-off reel. When coating the cable with asphalt powder, the cable on the pay-off reel can be pulled so that one end of the cable passes through the inside of the coating assembly 30 and connects to the take-up reel. Then, the two sets of drive assemblies 40 drive the pay-off reel and the take-up reel to rotate synchronously. When the pay-off reel rotates, it unwinds the cable, and when the take-up reel rotates, it winds the cable, so that the cable moves along the inside of the coating assembly 30. At the same time, the coating assembly 30 sprays asphalt powder onto the surface of the moving cable, thereby realizing the asphalt coating operation of the cable. When the coating assembly 30 sprays asphalt powder onto the surface of the cable, the excess asphalt powder is collected by the collection assembly 50. At the same time, the scraper assembly 60 scrapes off the asphalt powder collected by the collection assembly 50, thereby realizing the recycling of excess asphalt powder so that it can be reused and avoids waste of asphalt powder.

[0047] Please see Figure 1 , Figure 2 as well as Figure 3In one embodiment, the spraying assembly 30 includes a rectangular box 301, an asphalt powder spray pipe 302, a spraying plate 304, and an atomizing nozzle 305. The outer wall of the rectangular box 301 is fixedly connected to the supporting base plate 10 through a second bracket plate 303. The spraying plate 304 is fixedly installed on the inner top wall of the rectangular box 301. The spraying plate 304 is hollow inside. Several groups of atomizing nozzles 305 are provided, and several atomizing nozzles 305 are fixedly installed at the bottom of the spraying plate 304. One end of the asphalt powder spray pipe 302 is connected to an external air pump (not shown in the figure), and the other end is connected to the inner cavity of the spraying plate 304.

[0048] When spraying asphalt powder onto cables, the cable on the reel can be pulled so that one end of the cable passes through the inside of the rectangular box 301 and connects to the take-up reel. Then, the two sets of drive components 40 drive the two sets of reels 20 to rotate synchronously, thereby moving the cable along the inside of the rectangular box 301. When the cable moves, the asphalt powder is pumped through the asphalt powder spray pipe 302 to the inside of the spray plate 304 by an external air pump, and then sprayed out by several atomizing nozzles 305, thereby acting on the surface of the cable to realize the asphalt powder spraying operation of the cable.

[0049] Please see Figure 1 , Figure 2 as well as Figure 6 In one embodiment, the two sets of drive components 40 have identical structures, each including a U-shaped support plate 401, an annular support plate 402, an annular bevel rack 403, a transmission bevel gear 404, a support shaft 405, and a first motor 406. The annular support plate 402 is fixedly disposed on the side wall of the first support plate 101, the annular bevel rack 403 is fixedly disposed on the side of the annular support plate 402 away from the first support plate 101, the U-shaped support plate 401 is disposed inside the annular support plate 402, and the first motor 406 is fixedly mounted on the first support plate 101. On the side wall of a support plate 101, a U-shaped support plate 401 is mounted on the output shaft of the first motor 406. The coil 20 is disposed inside the U-shaped support plate 401. One end of the support shaft 405 is fixedly connected to the side wall of the coil 20, and the other end passes through the U-shaped support plate 401 and is fixedly connected to the transmission bevel gear 404. The support shaft 405 is rotatably engaged with the U-shaped support plate 401. The support shaft 405 is perpendicular to the output shaft of the first motor 406. The transmission bevel gear 404 meshes with the annular bevel rack 403.

[0050] The first motor 406 drives the U-shaped support plate 401 to rotate. The U-shaped support plate 401 drives the coil 20, support shaft 405, and transmission bevel gear 404 to rotate around the output shaft axis of the first motor 406. When the transmission bevel gear 404 rotates, it travels along one side of the annular bevel rack 403. Through the meshing action between the transmission bevel gear 404 and the annular bevel rack 403, the transmission bevel gear 404 can drive the support shaft 405 to rotate relative to the U-shaped support plate 401, thereby driving the coil 20 to rotate around the axis of the support shaft 405. Therefore, when the first motor 406 corresponding to the two sets of drive components 40 is working, the two sets of coils 20 can rotate around the output shaft of the first motor 406. On the one hand, the two sets of reels 20 can rotate around the axis of the support shaft 405. When the two sets of reels 20 rotate around the axis of the support shaft 405, the reel 20, which acts as the unwinding reel, unwinds the cable, and the reel 20, which acts as the take-up reel, unwinds the cable, so that the cable moves horizontally along the inside of the rectangular box 301 relative to the atomizing nozzles 305. When the two sets of reels 20 rotate around the axis of the output shaft of the first motor 406, the two sets of reels 20 can drive the cable to rotate inside the rectangular box 301, so that different surfaces of the cable face the atomizing nozzles 305, so that the atomizing nozzles 305 can spray asphalt powder onto different surfaces of the cable, thereby achieving uniform and comprehensive spraying of the cable.

[0051] Please see Figure 1 as well as Figure 2 In one embodiment, the collecting assembly 50 includes a belt roller 501, a transfer belt 502, a collecting belt 503, and a second motor 504. Two sets of belt rollers 501 are provided, respectively disposed on opposite sides of the rectangular box 301. The transfer belt 502 is sleeved between the two sets of belt rollers 501, and the collecting belt 503 is sleeved outside the transfer belt 502. The transfer belt 502 and the collecting belt 503 are divided into upper and lower parts. The upper part of the transfer belt 502 and the collecting belt 503 passes through the bottom inner side of the rectangular box 301, and the lower part of the transfer belt 502 and the collecting belt 503 passes through the bottom of the rectangular box 301. The second motor 504 is installed at the end of one set of belt rollers 501, and the scraping assembly 60 contacts the outer surface of the transfer belt 503.

[0052] When several atomizing nozzles 305 spray asphalt powder onto the cable surface, excess asphalt powder acts on the outer surface of the collecting belt 503. The second motor 504 drives one set of belt rollers 501 to rotate, which acts as the driving roller. The other set of belt rollers 501 rotates as the driven roller. The two sets of belt rollers 501 cooperate to drive the transfer belt 502 and the collecting belt 503 to operate. When the collecting belt 503 is operating, the asphalt powder acting on its outer surface is output from one end of the rectangular box 301. Then, as the collecting belt 503 continues to operate, the scraping assembly 60 scrapes off the asphalt powder on the outer surface of the collecting belt 503, thus cleaning the asphalt powder. This ensures that after the collecting belt 503 re-enters the rectangular box 301 from the other end, it can continue to collect excess asphalt powder again.

[0053] Please see Figure 4 In one embodiment, a plurality of first strip-shaped protrusions 5021 are spaced apart on the outer surface of the transfer belt 502. The plurality of first strip-shaped protrusions 5021 drive the outer surface of the transfer belt 502 to form a continuous convex-concave surface. The collecting belt 503 is arranged along the convex-concave surface and is thus defined into a convex-concave shape that matches the convex-concave surface.

[0054] The transfer belt 502 is driven by several first strip-shaped protrusions 5021 to form a continuous convex and concave surface on its outer surface, and the collection belt 503 is arranged along the convex and concave surface to form a convex and concave shape. This increases the surface area of ​​the collection belt 503, so as to better collect excess asphalt powder. When excess asphalt powder acts on the outer surface of the collection belt 503, it can enter the concave surface. With the operation of the transfer belt 502 and the collection belt 503, the excess asphalt powder can be smoothly carried out from the inside of the rectangular box 301.

[0055] Please see Figure 1 as well as Figure 5 In one embodiment, the length of the collecting belt 503 is greater than the length of the transfer belt 502, and a stripping roller 103 is provided on the upper part of the support base plate 10. The stripping roller 103 passes between the transfer belt 502 and the collecting belt 503 and is in contact with the inner surface of the collecting belt 503. The stripping roller 103 defines the collecting belt 503 into a triangular structure.

[0056] After the transfer belt 502 and the collection belt 503 are rotated out from one end of the rectangular box 301, the collection belt 503 is separated from the outer surface of the collection belt 503 under the limiting action of the peeling roller 103. At this time, the collection belt 503, which was originally defined into a convex and concave shape by several first strip protrusions 5021, can be straightened so that the scraping assembly 60 can smoothly scrape off the asphalt powder on the outer surface of the collection belt 503, thereby improving the scraping and cleaning effect of the asphalt powder.

[0057] Please see Figure 1 as well as Figure 2 In one embodiment, a pressing assembly is also provided on the side of one of the sets of rollers 501. After the asphalt powder on the outer surface of the collecting belt 503 is scraped off, the pressing assembly is used to press the collecting belt 503 so that the collecting belt 503 is rearranged along the convex and concave surfaces so that when the transfer belt 502 and the collecting belt 503 subsequently re-enter the rectangular box 301, the collecting belt 503 can effectively collect any remaining asphalt powder.

[0058] Please see Figure 2 as well as Figure 7 In one embodiment, the pressing assembly includes a first spur gear 505, a second spur gear 506, and a pressing roller 507. The pressing roller 507 is disposed on one side of one group of belt rollers 501 and distributed along the length direction of the group of belt rollers 501. A plurality of second strip-shaped protrusions 5071 distributed in annular intervals are fixedly disposed on the circumferential sidewall of the pressing roller 507. The first spur gear 505 is fixedly disposed at the end of the group of belt rollers 501, and the second spur gear 506 is fixedly disposed at the end of the pressing roller 507 and meshes with the first spur gear 505.

[0059] When the second motor 504 drives one set of belt rollers 501 to rotate, thereby driving the transfer belt 502 and the collection belt 503 to operate, the set of belt rollers 501 drives the first spur gear 505 to rotate synchronously. When the first spur gear 505 rotates, it drives the pressing roller 507 to rotate through meshing with the second spur gear 506. When the pressing roller 507 rotates, it drives several second strip-shaped protrusions 5071 to rotate. When the several second strip-shaped protrusions 5071 rotate, they interact with several first strip-shaped protrusions 5071 on the outer surface of the transfer belt 502. 21 interlock with each other, thereby pressing the straightened collection belt 503 back into the space between the two adjacent sets of first strip protrusions 5021, so that the collection belt 503 reshapes into a convex-concave shape. Subsequently, as the transfer belt 502 and the collection belt 503 re-enter the rectangular box 301, they can effectively collect excess asphalt powder again. During the interlocking process of the several second strip protrusions 5071 and the several first strip protrusions 5021, the collection belt 503 is pulled and thus runs synchronously with the transfer belt 502.

[0060] Please see Figure 5 In one embodiment, the scraping assembly 60 includes a scraper blade, the upper end of which contacts the outer surface of the collecting belt 503, which is straightened by the stripping roller 103.

[0061] When several second strip protrusions 5071 and several first strip protrusions 5021 engage with each other and pull the collecting belt 503 so that the collecting belt 503 moves synchronously with the transfer belt 502, the outer surface of the collecting belt 503 moves relative to the scraper, and the scraper scrapes off the asphalt powder on the outer surface of the collecting belt 503.

[0062] Please see Figure 1 In one embodiment, a recycling bin 102 is also provided on the upper part of the supporting base plate 10, and the scraper is fixedly installed inside the recycling bin 102.

[0063] After the scraper removes the asphalt powder from the outer surface of the collecting belt 503, the asphalt powder can fall into the recycling box 102 for storage.

[0064] In this embodiment of the invention, for ease of understanding, one set of reels 20 is referred to as the pay-off reel, and the other set of reels 20 is referred to as the take-up reel. The pay-off reel has a cable to be coated with asphalt powder wound on it. When coating the cable with asphalt powder, the cable on the pay-off reel can be pulled, causing one end of the cable to pass through the inside of the coating assembly 30 and connect to the take-up reel. Then, the two sets of drive assemblies 40 drive the pay-off reel and the take-up reel to rotate synchronously. When the pay-off reel rotates, it unwinds the cable; when the take-up reel rotates, it winds the cable, causing the cable to move along the inside of the coating assembly 30. Simultaneously, the cable passes through the coating assembly 30... The asphalt powder is sprayed onto the surface of a moving cable to achieve the asphalt spraying operation. When the spraying component 30 sprays the asphalt powder onto the cable surface, the excess asphalt powder is collected by the collecting component 50. At the same time, the scraping component 60 scrapes off the asphalt powder collected by the collecting component 50, thereby realizing the recycling of excess asphalt powder so that it can be reused and avoids waste of asphalt powder. Compared with the existing technology, when spraying asphalt onto cables, excess asphalt can be recycled and reused, thereby achieving the purpose of energy saving and environmental protection.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0066] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity, and those skilled in the art should consider the specification as a whole.
