DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

The side walls at both ends of the spray shell 3 are respectively provided with an inlet 301 and an outlet 302 whose central axes coincide with each other. The first coating component 4 and the second coating component are respectively arranged in the spray shell 3 along the moving direction of the cable line; the first coating component 4 includes a plurality of first coating units, and the plurality of first coating units are arranged in the spray shell 3 at equal angles along the central axis direction of the inlet 301. In this scheme, the first coating component 4 is provided, and the first coating component 4 includes a plurality of first coating units. It is worth noting that the first coating component 4 of this scheme also includes a plurality of driving cylinders, and the plurality of driving cylinders are matched with the plurality of first coating units one by one. The output end of any driving cylinder is connected to the corresponding first coating unit. The plurality of first coating units jointly form a first through groove, and the driving cylinder is used to drive the corresponding first coating unit to move, thereby changing the diameter size of the first through groove. Since the diameter of the first through groove will change, adjacent first coating units are not arranged to fit each other, so that the first coating component 4 cannot spray the anti-corrosion coating on the passing cables at one time. Furthermore, the present scheme is provided with a second coating component, which includes a plurality of second coating units, and the plurality of second coating units are arranged in the spray shell 3 at equal angles along the central axis direction of the feed port 301, and the central axis of the second coating unit and the central axis of the first coating unit are parallel to the central axis of the feed port 301, and the central axis of the second coating unit is located in the middle of the gap between the two first coating units; in addition, the diameter of the second through groove formed by the plurality of second coating units of the present scheme is always consistent with the diameter of the first through groove, and the central axis of the first through groove coincides with the central axis of the second through groove. The function of the second coating component of the present scheme is to The cable line that has been sprayed with anti-corrosion paint by the first coating component 4 is subjected to secondary treatment, and the part of the cable line that has not been sprayed with anti-corrosion paint is sprayed to achieve spraying of the entire cable line, which solves the problem that the existing spraying treatment of the cable line is to spray the outer wall of the cable line by setting a paint nozzle with a rotatable angle and variable height. Such a setting will not only cause repeated spraying in some areas of the outer wall of the cable line, resulting in waste of paint; secondly, a single paint nozzle needs to spray one circle of the cable line, and more actions need to be performed, which will actually reduce the spraying speed and efficiency of the entire device.

[0021] In order to ensure the normal operation of the device, it is necessary to ensure that the cable entering the spray shell 3 will not swing left and right. The present solution also includes two positioning rings 5, and the two positioning rings 5 ​​are respectively arranged at both ends of the spray shell 3. The positioning ring 5 is arranged between the cable drum 1 and the spray shell 3, and the other positioning ring 5 is arranged between the spray shell 3 and the winding assembly 2. The central axis of the positioning ring 5 coincides with the central axis of the feed port 301.

[0022] Furthermore, the first coating component 4 of the present solution further includes a first coating box 401, a plurality of first coating tubes 402 and a first coating pump 403, the first coating pump 403 is connected to the first coating box 401, the plurality of first coating tubes 402 are matched with the plurality of first coating units in a one-to-one correspondence, and the two ends of any first coating tube 402 are respectively connected to the first coating unit and the first coating box 401; specifically, the first coating unit of the present solution includes a first coating shell 404 with a hollow interior, a push rod 405, a push block 406 and a discharge valve 6, and the first coating shell A through hole and a discharge hole are respectively provided at the top and the bottom of 404, a push rod 405 is slidably disposed in the first paint shell 404, a push block 406 is connected to the push rod 405, and the push block 406 is slidably and sealedly disposed in the first paint shell 404, the push block 406 divides the space in the first paint shell 404 into a first space and a second space, the through hole and the discharge hole are both located in the second space, one end of the first paint tube 402 is interconnected with the through hole, a discharge valve 6 is disposed in the discharge hole, and the discharge valve 6 can lock or release its sealing cooperation relationship with the discharge hole. It is worth noting that, in this solution, a first paint pump 403 is provided, and the first paint pump 403 transfers the paint in the first paint box 401 to the second space of the first paint housing 404 through the first paint pipe 402. In addition, a one-way valve is also provided at the connection between the first paint pipe 402 and the first paint housing 404 of this solution, so that the paint can only enter the first paint housing 404 through the first paint pipe 402, and cannot flow back from the first paint housing 404 to the first paint pipe 402; when the push block 406 starts to slide, the space of the second space becomes smaller, and the paint pressure in the second space increases, which compresses the discharge valve 6 to release its sealing matching relationship with the discharge hole, and the paint in the second space will flow to the cable through the discharge valve 6. When the space of the second space becomes larger, the paint pressure in the second space decreases, and at this time, the discharge valve 6 re-locks its sealing matching relationship with the discharge hole, and the paint in the second space cannot flow to the cable through the discharge valve 6.

[0023] Specifically, the present solution also includes a control module 9, and the first coating unit also includes a drive cylinder 407. The control module 9 is arranged on the side wall of the discharge port 302, and the drive cylinder 407 is arranged in the first space. The output end of the drive cylinder 407 is connected to the end of the push rod 405 away from the push block 406. The drive cylinder 407 is in communication connection with the control module 9. The control module 9 can lock or release the press-fit relationship between it and the cable. When a cable extends through the discharge port 302, the control module 9 arranged on the discharge port 302 will achieve press-fit with the cable, and the control module 9 will control the drive cylinder 407 to move to achieve the back and forth movement of the push block 406. It is worth noting that the diameter size of the feed port 301 and the discharge port 302 of the present solution will change, and the diameter size of the feed port 301 and the diameter size of the discharge port 302 are always the same as the diameter size of the first through groove.

[0024] It is also worth noting that the structure of the second coating unit of the present solution is consistent with that of the first coating unit, and the control module 9 is communicatively connected with the driving cylinder 407 of the second coating unit.

[0025] The above embodiment mentioned that before the first coating component 4 and the second coating component of the present scheme need to spray the cable, it is necessary to press the control module 9 arranged at the discharge port 302. If the cable is directly pressed to press the control module 9 to drive the first coating component 4 and the second coating component to work, it cannot be guaranteed that when the device starts working, the cable between the discharge port 302 and the discharge hole of the first coating component 4 is sprayed; based on this, the present scheme also includes a guide rod 7 and a connecting rod 8, the connecting rod 8 is coaxially arranged at one end of the guide rod 7, the outer wall of the connecting rod 8 is fitted with the inner wall of one end of the cable, and the end face of the guide rod 7 is fitted with the end face of one end of the cable; in addition, the length of the guide rod 7 of the present scheme is equal to the distance between the discharge port 302 and the discharge hole of the first coating unit, and the outer wall diameter of the guide rod 7 is equal to the outer wall diameter of the cable. Through such a setting, when the guide rod 7 presses the control module 9, the cable is located at the position of the discharge hole of the first coating component 4, so that the device can spray all the cables.

[0026] Specifically, the discharge valve 6 of the present solution includes a discharge shell 601 with a hollow interior, a discharge round block 602, a lifting spring 603 and a plurality of sealing units 11, the discharge shell 601 can be slidably arranged in the discharge hole, the two ends of the lifting spring 603 are respectively connected to the discharge shell 601 and the first coating shell 404, the discharge round block 602 is coaxially sealed and arranged in the discharge shell 601, and the discharge round block 602 is provided with a plurality of sealing holes around its central axis, and the plurality of sealing holes are matched with a plurality of sealing units 11 in a one-to-one correspondence, and any sealing unit 11 can lock or release its matching relationship with the corresponding sealing hole; it should be noted that the sealing unit 11 of the present solution includes a sealing block 1101, a sealing spring 1102 and a connecting rope 1103. 03. The unloading shell 601 is provided with a plurality of sliding grooves, which are matched with a plurality of sealing holes in a one-to-one correspondence. Any sliding groove is interconnected with the corresponding sealing hole to form a sliding space. The sealing block 1101 is slidably sealed in the sliding space. The sealing spring 1102 is arranged in the sliding space. The two ends of the sealing spring 1102 are respectively connected with the sealing block 1101 and the unloading shell 601; the first coating shell 404 is also provided with a plurality of connecting grooves, which are matched with a plurality of sliding spaces in a one-to-one correspondence. Any connecting groove is interconnected with the corresponding sliding space. The connecting rope 1103 is arranged in the corresponding connecting groove. The two ends of the connecting rope 1103 are respectively connected with the sealing block 1101 and the first coating shell 404.

[0027] It is worth mentioning that the working principle of the unloading valve 6 of the present scheme is: when the control module 9 is pressed, the driving cylinder 407 arranged in the first coating shell 404 starts to work, and controls the corresponding pushing rod 405 to move, causing the pushing block 406 to move in the direction close to the unloading hole, thereby causing the space in the second space to decrease, so that the coating pressure in the second space increases, thereby achieving the height reduction of the pressing unloading shell 601. Due to the height reduction of the unloading shell 601, the distance between the sealing block 1101 and the first coating shell 404 increases, and the length of the connecting rope 1103 does not change. Therefore, in the process of the height reduction of the unloading shell 601, the connecting rope 1103 will pull the sealing block 1101 to move in the direction of shrinking in the sliding groove, and the sealing block 1101 releases its connection with the unloading shell. The sealing cooperation relationship of the round block 602, and the paint in the second space flows through the sealing hole and is sprayed onto the outer wall of the cable; when the paint pressure in the second space decreases, the height of the unloading shell 601 will rise again due to the force of the lifting spring 603 and return to its original position. At this time, the sealing block 1101 will realize a sealing cooperation relationship with the unloading round block 602 again due to the force of the sealing spring 1102, and the paint in the second space will no longer flow through the sealing hole to the outside of the first paint shell 404; it should also be noted that when the first paint unit is spraying the cable, the drive cylinder 407 is always moving back and forth, and as long as the speed is fast enough, the cable can be continuously sprayed.

[0028] It should also be noted that, since the first coating component 4 and the second coating component are both arranged before the control module 9, such an arrangement results in that, after the first coating component 4 is completed at the end of the cable, the first coating component 4 continues to flow the coating toward the outside of the first coating shell 404, thereby causing a waste of coating. In order to avoid this situation, the present solution also includes a locking unit 10. First of all, it should be noted in advance that when the bottom surface of the discharge shell 601 of the present solution is flush with the bottom surface of the discharge hole, the sealing block 1101 releases its contact with the sealing The sealing matching relationship of the discharge housing 601 and the discharge hole; when the top surface of the discharge housing 601 is flush with the top surface of the discharge hole, the sealing block 1101 locks the sealing matching relationship between the sealing block 1101 and the sealing hole; that is, when the sealing block 1101 locks the sealing matching relationship between the sealing block 1101 and the sealing hole, the bottom surface of the discharge housing 601 and the bottom surface of the discharge hole are separated by a distance, and this scheme defines this space as a locking space, and the locking unit 10 is arranged in the locking space; specifically, the locking unit 10 is arranged in the first coating material housing 404, and the locking unit 10 includes a locking rod 1001, a locking spring 1 002, vertical rod 1003, abutment rod 1004 and hinge rod 1005, the locking rod 1001 is slidably arranged in the first coating shell 404 along the sliding direction of the cable, the two ends of the locking spring 1002 are respectively connected to the locking rod 1001 and the first coating shell 404, one end of the locking rod 1001 can lock or release the matching relationship of extending into the discharge hole, when the top surface of the discharge shell 601 is flush with the top surface of the discharge hole, the top surface of the locking rod 1001 and the bottom surface of the discharge shell 601 are in the same plane; the vertical rod 1003 is vertical It is vertically connected to the locking rod 1001, and the vertical rod 1003 is provided with a vertical groove along its axial direction. The hinged rod 1005 is inclined, and the middle end of the hinged rod 1005 is hinged to the first paint shell 404. The higher end of the hinged rod 1005 can be slidably hinged to the vertical groove, and the other end of the hinged rod 1005 is abutted against the abutment rod 1004. The abutment rod 1004 is vertically slidably set in the first paint shell 404, and one end of the abutment rod 1004 can lock or release its matching relationship extending out of the first paint shell 404.

[0029] It should be noted that when the cable is not extended into the spray device, at this time, one end of the abutment rod 1004 extends into the first through groove of the first coating component 4; when the cable is extended into the spray device, the cable will lock its press-fit relationship with the abutment rod 1004, thereby causing the abutment rod 1004 of this scheme to shrink into the first coating component 4, and as the abutment rod 1004 slides vertically toward the top, the originally inclined hinged rod 1005, its inclination angle gradually decreases, and then the vertical rod 1003 slidably hinged to the higher end of the hinged rod 1005 slides in the direction away from the discharge hole, thereby driving the locking rod 1001 to move along with the movement of the vertical rod 1003, so that the locking rod 1001 releases its abutment relationship with the discharge shell 601, thereby allowing the discharge shell 601 to be raised and lowered as the coating pressure in the second space changes; when the end of the cable is After the spraying process of the first coating component 4 is completed, since the cable no longer abuts against the abutment rod 1004, the abutment rod 1004 will be re-extended into the first through groove of the first coating component 4 due to the action of gravity, and the locking rod 1001 will be re-extended into the unloading hole due to the locking spring 1002, thereby realizing the abutment relationship between the locking rod 1001 and the unloading shell 601, thereby locking the unloading shell 601 and preventing it from moving up and down, and the paint located in the second space cannot flow out of the first coating shell 404 through the unloading valve 6. It should be noted that a pressure module is provided in the second space in the first coating shell 404 of this scheme, and the pressure module is used to detect the paint pressure in the second space. When the pressure module detects that the paint pressure in the second space exceeds a certain level, the pressure module will transmit a signal to the control module 9, and the control module 9 will control the drive cylinder 407 to stop working.
