Description

Technical Field

[0001] The utility model relates to the technical field of optical cable steel wire processing equipment, specifically an optical cable steel wire hot melt adhesive coating device. Background Technique

[0002] An optical cable is a cable structure composed of placing one or more optical fibers in loose tubes, then placing these tubes in a strong and well-protective outer skin, and finally coating with a moisture-proof, anti-compound, and metal protective layer. As a hard, corrosion-resistant, and oxidation-resistant material, steel wire is usually embedded in the protective layer of the optical cable, playing a role in supporting, strengthening, and protecting, and can protect the optical fiber from external pressure and other damages. Generally, the steel wire used in the optical cable is called the optical cable strengthening core.

[0003] In the prior art, such as a coating device for producing an optical cable strengthening core proposed in the patent application number "CN202320454886.1", the functions of quickly and evenly coating the optical cable strengthening core are achieved through the installation of a motor, a first gear, a first annular groove, a ball, a rotating block, a second annular groove, a second gear, and a scraper. The scraper evenly smears the glue on the optical cable strengthening core, so that the periphery of the optical cable strengthening core is evenly coated with glue, thus achieving the function of quickly and evenly coating the optical cable strengthening core.

[0004] However, in the above patent application, when coating glue on the optical cable strengthening core, first, the glue is sprayed on the moving strengthening core through a nozzle, and then the scraper is used to smear the glue on the surface of the strengthening core. However, the sprayed glue cannot ensure accurate and comprehensive adhesion to the outer walls of all the strengthening cores to be coated, especially the part of the strengthening core opposite to the nozzle, where the situation of missed coating is likely to occur, resulting in difficulty in ensuring the uniformity of coating during the subsequent scraping by the scraper, and the sprayed glue cannot be well collected centrally, which is likely to cause pollution to the working environment.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 creative efforts shall fall within the protection scope of the present invention.

[0029] The optical cable steel wire hot melt glue coating equipment is used for coating the steel wire body 14 with glue, and includes a base plate 1. A frame 2 is fixedly installed on the upper surface of the base plate 1. A glue tank 4 is fixedly installed on the upper surface of the frame 2. Two support plates 33 are fixedly installed on the upper surface of the base plate 1. A spraying chamber 3 is fixedly installed on the upper ends of the two support plates 33. A glue spraying mechanism is arranged inside the spraying chamber 3. A pretreatment mechanism is arranged at a position near one side of the inner top of the frame 2. Two guide rollers 6 are rotatably connected to both inner side walls of the frame 2. The glue spraying mechanism includes two annular glue storage bins 15. The two annular glue storage bins 15 are both movably installed inside the spraying chamber 3, and the two annular glue storage bins 15 are respectively located near both sides inside the spraying chamber 3. Ring grooves 18 are opened on both inner side walls of the spraying chamber 3.

[0030] A number of sliding rods 19 are inserted into each of the two annular grooves 18, and one end of each sliding rod 19 is fixedly connected to the annular glue storage bin 15. A number of spray nozzles 20 are fixedly installed on the inner wall of the annular glue storage bin 15. The outer wall of the annular glue storage bin 15 is fixedly connected to an annular connecting plate 16. A number of tooth grooves are formed on the outer wall of the annular connecting plate 16. U-shaped plates 31 are installed on the upper surface of the spraying bin 3 near both sides. A gear 17 is rotatably connected inside the U-shaped plate 31 through a shaft rod, and the gear 17 is meshed with a number of tooth grooves. A motor one is installed on the outer side wall of the U-shaped plate 31, and the output end of the motor one is connected to the gear 17 through a shaft rod. When the annular glue storage bin 15 rotates, the sliding rod 19 moves along the annular groove 18 following the annular glue storage bin 15, and the cross-section of the sliding rod 19 is L-shaped, which fits with the annular groove 18, and can limit the rotation position of the annular glue storage bin 15 to prevent the annular glue storage bin 15 from separating from the spraying bin 3.

[0031] Annular sheets 21 are slidably installed on the outer side walls of both annular glue storage bins 15. A glue pump one 23 is installed on the upper surface of the frame 2 near one side of the glue tank 4. One end of the glue pump one 23 is fixedly connected to a connecting pipe three 29, and the other end of the glue pump one 23 is fixedly connected to a glue inlet pipe one 24. The end of the glue inlet pipe one 24 away from the glue pump one 23 is fixedly connected to the annular sheet 21. A glue inlet pipe two 25 is fixedly connected to the outer wall of the glue inlet pipe one 24, and one end of the glue inlet pipe two 25 is fixedly connected to another annular sheet 21. One end of the glue inlet pipe one 24 is communicated with the annular glue storage bin 15, and one end of the glue inlet pipe two 25 is communicated with another annular glue storage bin 15. Due to the limitation of the positions of the two annular sheets 21 by the glue inlet pipe one 24 and the glue inlet pipe two 25 respectively, when the annular glue storage bin 15 rotates, the position of the annular sheet 21 remains unchanged, and one side of the annular glue storage bin 15 slides and rotates along the outer wall of the annular sheet 21.

[0032] A glue pump two 26 is installed on the outer side wall of the frame 2. One end of the glue pump two 26 is fixedly connected to a connecting pipe two 28, and one end of the connecting pipe two 28 is fixedly connected to the spraying bin 3.

[0033] Two fixing plates 32 are fixedly installed on both outer side walls of the frame 2. A winding shaft 5 is rotatably connected between the two fixing plates 32. A motor three is installed on the outer side wall of the fixing plate 32, and the output end of the motor three is connected to the winding shaft 5. A cavity is formed in the inner wall of the glue tank 4, and a number of heating rods 22 are installed inside the cavity. A glue adding pipe is installed on the upper surface of the glue tank 4, and glue can be added into the glue tank 4 through the glue adding pipe.

[0034] When in use, one end of the steel wire 14 wound on one of the winding shafts 5 passes through the frame 2 and passes between the two guide rollers 6, then passes through the annular plate 10 and the annular plate 2 11 and the internal position of the spraying bin 3, and finally passes through the other two guide rollers 6 to connect with the winding shaft 5, and then the motor 3 on the fixed plate 32 drives the winding shaft 5 to rotate, and the steel wire 14 is wound, so that the steel wire 14 starts to transmit. During transmission, the motor 1 on the U-shaped plate 31 drives the gear 17 to rotate, cooperates with each tooth groove, drives the annular connecting plate 16 to rotate, thereby driving the annular glue storage bin 15 to rotate, and each nozzle 20 follows the annular glue storage bin 15 to rotate around the steel wire body 14, and at the same time, the hot melt glue heated by the heating rod 22 in the glue box 4 is pumped out to the glue inlet pipe 1 24 through the glue pump 1 23 in cooperation with the connecting pipe 3 29, and enters the annular glue storage bin 15, and is sprayed by each nozzle 20 to the outer wall of the steel wire body 14, thereby achieving preliminary surrounding glue spraying of the steel wire body 14, and a part of it is diverted by the glue inlet pipe 25 to another annular glue storage bin 15, and is also sprayed by each nozzle 20 to surround the steel wire body 14 that has been initially surrounded by glue spraying again, thereby achieving full coating of the steel wire body 14 with hot melt glue, avoiding missing coating, and spraying evenly;

[0035] The excess hot melt adhesive sprayed onto the steel wire body 14 is all accumulated near the lower part of the spray chamber 3, which will not cause pollution to the working environment. Moreover, through the glue pump 26 and the connecting pipe 2 28, the excess hot melt adhesive accumulated in the spray chamber 3 can be pumped back into the glue box 4 through the connecting pipe 1 27 for secondary spraying to avoid waste.

[0036] The pretreatment mechanism includes a transverse groove 7, which is opened through the top position of the frame 2. A reciprocating screw 8 is rotatably connected inside the transverse groove 7, and a slide 9 is provided on the outside of the reciprocating screw 8. The bottom end of the slide 9 is fixedly connected to an annular plate 10, and an annular plate 2 11 is fixedly installed on one side of the annular plate 10. A motor 2 is installed on the outer wall of the frame 2, and the output end of the motor 2 is connected to one end of the reciprocating screw 8. A number of rolling balls 13 are fixedly installed on the inner wall of the annular plate 2 11, and an annular sponge plate 12 is fixedly installed on the inner wall of the annular plate 10.

[0037] Specifically, when the steel wire body 14 is driven, the steel wire body 14 that has not entered the spraying chamber 3 first passes through the inner positions of the first annular plate 10 and the second annular plate 11. At the same time, the reciprocating lead screw 8 is rotated by the second motor, which can drive the slide plate 9 to move left and right, thereby driving the first annular plate 10 and the second annular plate 11 to move reciprocally left and right. The annular sponge plate 12 and each ball 13 follow the reciprocating movement left and right. Moreover, the inner wall of the annular sponge plate 12 closely adheres to the outer wall of the steel wire body 14, which can wipe and clean the driven steel wire body 14 back and forth. At the same time, each ball 13 also closely adheres to the outer wall of the driven steel wire body 14, which can roll and straighten the steel wire body 14 back and forth. Thus, the steel wire body 14 to be coated with glue can be cleaned to avoid the blockage caused by dust and other impurities adhering to the steel wire body 14. At the same time, straightening treatment is carried out to avoid bending, resulting in coating dead angles and affecting the coating effect.

[0038] The above shows and describes 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 by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
