Description

Technical Field

[0001] The invention relates to the technical field of pipe fitting processing, and in particular to a multifunctional pipe fitting spraying device. Background Art

[0002] The main purpose of pipe surface spraying is to prevent corrosion, rust, beautify and prolong service life. Through spraying, a protective film can be formed on the surface of the pipe to isolate corrosive factors such as air and moisture, thereby achieving the purpose of protecting the pipe. At present, most of the coatings are evenly applied on the surface of the pipe by using tools such as spray guns or brushes to ensure uniform coating without missing or sagging.

[0003] For example, the Chinese invention patent with publication number CN110302921B provides a CNC machine tool for metal pipe processing. The device solves the technical problems that the existing spraying equipment cannot adjust the nozzle range of the nozzle according to the diameter of the pipe, resulting in low spraying efficiency. At the same time, due to the different diameters of the pipes during spraying, the distance between the nozzle and the pipe is different, resulting in uneven spraying force, making it impossible for the spraying agent to be sprayed on the outer wall of the pipe.

[0004] Another example is the Chinese invention patent with publication number CN116809277B, which provides an anti-corrosion paint coating device for fire-fighting pipe fittings. The device can control the movement of a driving plate to drive the pipe fittings to be coated to move along a guide ring. When passing through a coating nozzle, the coating nozzle will spray anti-corrosion paint on the pipe fittings. This method can improve the coating efficiency of the anti-corrosion paint and facilitate batch production of pipe fittings.

[0005] It can be seen that the current pipe spraying is mostly carried out by spraying paint through a nozzle. However, after the nozzle stops spraying for a period of time, the paint is easy to solidify and harden, causing the nozzle to be blocked. If the nozzle is blocked, it is necessary to stop the machine and then manually clean or replace the blocked nozzle. It is inconvenient to clean the nozzle quickly, which leads to a decrease in spraying efficiency and an increase in the labor cost of the staff. Summary of the invention

[0040] 1. When the device is in use, the pipe fittings are transported to the support ring through the conveying mechanism, and the paint is supplied to multiple groups of nozzles through the external feeding system, and sprayed onto the surface of the pipe fittings through the spray holes. In the process of spraying, the installation ring can be controlled to rotate back and forth by the power mechanism, so that the paint spraying is more uniform. At the same time, the power mechanism provides power to the conveying mechanism to transport the pipe fittings to continuously spray the pipe fittings. If the spray hole is blocked during the spraying process, the drive frame can be moved downward. During the movement, the drive frame drives multiple groups of cleaning needle holders to rise and fall in the spray hole through the drive mechanism to dredge the spray hole, so that the nozzle cleaning work can be completed quickly without stopping the entire device, effectively preventing the nozzle from being blocked, and no manual cleaning is required, which reduces the labor cost of the staff and improves the spraying efficiency.

[0041] 2. When the device is in use, the driving motor drives the first synchronous wheel to rotate, and drives the second synchronous wheel to rotate through the tension wheel. During the rotation process, the second synchronous wheel drives one set of conveying rollers to rotate through the cooperation of the first bevel gear and the second bevel gear, and drives the other set of conveying rollers to rotate in the opposite direction under the action of the reversing belt. During the rotation process, the two sets of conveying rollers control the conveying rollers to rotate through the belt transmission mechanism to convey the pipes. In the process of cleaning the nozzle by controlling the movement of the driving frame, the driving frame moves down to press the tension wheel, and the slider on one side of the tension wheel compresses the first elastic member, so that the synchronous belt is relaxed, and the conveying roller stops rotating at this time, so that the continuous transmission of the pipe is avoided during the cleaning process of the nozzle, resulting in gaps in the spraying, and there is no need to control the start and stop of the pipe conveying separately, so that the cleaning is synchronized with the stopping of the pipe conveying, which can prevent the gaps in the spraying caused by the untimely stopping of the conveying, and can also prevent the uneven thickness of the spraying caused by the premature stopping of the conveying, further improving the efficiency of the spraying.

[0042] 3. When the device is in use, the pulling block and the pushing column follow the movement of the mounting ring, so that the cleaning ring rotates accordingly. In the process of cleaning the nozzle by moving the driving frame, the control frame at one end of the driving frame pulls the pulling block upward. During the movement of the pulling block, the cleaning ring is controlled to slide along its axis through the cooperation of the pushing column and the inclined track until the cleaning brush extends out and contacts the ends of multiple groups of nozzles, thereby removing impurities pushed out by the cleaning needle frame, further avoiding impurities from adhering to the nozzle, and improving the cleaning effect.

[0065] When in use, the pipe is passed through the support ring 102, and the drive motor 301 can be controlled to start, driving the eccentrically arranged mounting column 302 on its output shaft to make circumferential movement, and then the mounting ring 103 is driven to reciprocate on the support ring 102 through the drive rod 104. During the reciprocating rotation of the mounting ring 103, the paint can be supplied to multiple groups of nozzles 105 through an external feeding system. The paint is pressurized and sprayed from the spray hole 106 onto the pipe, completing the spraying of the pipe. During the spraying process, the movement of the nozzle 105 is controlled to make the spraying of the pipe more uniform.

[0066] like Figures 1 to 4As shown, in this embodiment, a conveying mechanism is also provided on the frame 101, and the power mechanism is connected to the conveying mechanism to drive the conveying mechanism to convey the pipe. The conveying mechanism includes two groups of rotatable conveying rollers 702 arranged on the frame 101, the two groups of conveying rollers 702 are connected by a reversing belt 703, two groups of movable frames 704 are respectively hinged on the two groups of conveying rollers 702, and conveying rollers 706 connected by a belt transmission mechanism 705 are arranged on the two groups of conveying rollers 702. The two groups of conveying rollers 706 are respectively rotatably arranged on the two groups of movable frames 704, and a gap is formed for the pipe to pass through, and the movable frame 704 is connected to the frame 101 by a second tension spring 707. A linkage assembly is arranged on the output shaft of the driving motor 301, and the power of the driving motor 301 is converted into driving one of the groups of conveying rollers 702 to rotate through the linkage assembly. The linkage assembly includes a first synchronous wheel 303 arranged on the output shaft of the driving motor 301, a second synchronous wheel 307 and a tensioning wheel 304 are rotatably arranged on one side of the frame 101, a first bevel gear 309 is arranged on the second synchronous wheel 307, a second bevel gear 701 meshing with the first bevel gear 309 is arranged at the bottom of a group of conveying rollers 702, and the tensioning wheel 304 is connected to the first synchronous wheel 303 and the second synchronous wheel 307 through a synchronous belt 308.

[0067] When the driving motor 301 is started, it drives the first synchronous wheel 303 to rotate. During the rotation process, the first synchronous wheel 303 drives the second synchronous wheel 307 to rotate through the cooperation of the synchronous belt 308 and the tension wheel 304. During the rotation process, the second synchronous wheel 307 drives one set of conveying rollers 702 to rotate through the meshing of the first bevel gear 309 and the second bevel gear 701, and then drives the other set of conveying rollers 702 to rotate in the opposite direction through the reversing belt 703. During the rotation process, the conveying roller 702 can drive the two sets of conveying rollers 706 to move in opposite directions respectively through the belt transmission mechanism 705, so as to convey the pipes between the two sets of conveying rollers 706, thereby achieving the purpose of synchronously controlling the conveying of pipes and controlling the movement of the nozzle 105. And under the action of the second tension spring 707, the two sets of movable frames 704 rotate and close along the axis of the conveying roller 702, so as to control the two sets of conveying rollers 706 to be close to the outer wall of the pipe, so as to convey pipes of different diameters and make the conveying of pipes more stable.

[0068] like Figures 1 to 4 As shown, in this embodiment, a slider 305 is provided on the frame 101 so as to be liftable, a first elastic member 306 is provided between the slider 305 and the frame 101, and the tensioning wheel 304 is rotatably provided on the slider 305. After the driving frame 501 swings, it can abut against the tensioning wheel 304 to drive the slider 305 to slide. After the slider 305 slides, it drives the tensioning wheel 304 to move downward, thereby relaxing the synchronous belt 308 to stop driving the conveying roller 702 to rotate, thereby stopping the conveying of the pipe.

[0069] like Figure 2 , Figures 5 to 10 As shown, in this embodiment, a driving mechanism is provided on the support ring 102 , and the driving mechanism is connected to the driving frame 501 and the multiple cleaning needle frames 108 to convert the swing of the driving frame 501 into driving the multiple cleaning needle frames 108 to rise and fall in the spray hole 106 . The driving mechanism includes a sealing frame 107, which is movably arranged on the outer wall of the nozzle 105 and sealed therewith, the sealing frame 107 is connected to the cleaning needle frame 108, a driving column 109 is arranged on the sealing frame 107, a driving ring 201 is arranged on the support ring 102, the driving ring 201 is fixedly connected to the mounting ring 103 through a connecting assembly, a driving disk 202 is arranged on one side of the driving ring 201, a plurality of groups of inclined grooves 203 are provided on the driving disk 202, and the plurality of groups of driving columns 109 are respectively slidably clamped in the plurality of groups of inclined grooves 203, and the connecting assembly includes two groups of abutment plates 402 arranged at intervals, the two groups of abutment plates 402 are respectively arranged on the inner and outer sides of the driving ring 201, wherein a second elastic member 404 is arranged between the two groups of abutment plates 402 and the driving ring 201, and the two groups of abutment plates 402 are fixedly connected through a locking column 403, and the end of the locking column 403 is penetrated into the opening on the mounting ring 103.

[0070] In the initial state, under the action of the second elastic member 404, the locking column 403 arranged on the driving ring 201 is inserted into the opening on the mounting ring 103, so that the mounting ring 103 can drive the driving ring 201 to follow the movement during the reciprocating rotation. The driving frame 501 is provided with a control component connected to the connecting component, and the fixed connection between the connecting component and the mounting ring 103 is released by the control component when the driving frame 501 swings, and the position of the driving ring 201 is fixed. The control component includes a movable column 401 arranged on a group of abutment plates 402 located on the inner side of the driving ring 201, and a pull block 405 is arranged on the movable column 401, and the pull block 405 has a larger diameter than the movable column 401, and the driving frame 501 is provided with a control frame 502, and a limiting groove 503 is provided on the control frame 502, and the movable column 401 is slidably arranged in the limiting groove 503, and the end of the limiting groove 503 is provided with a card slot 504 adapted to the pull block 405.

[0071] In the initial state, the driving frame 501 does not move, so that the movable column 401 slides in the limiting groove 503. When the nozzle 105 needs to be cleaned, the driving frame 501 can be moved downward, and the button 506 for controlling the pause of the feeding system on the driving frame 501 is pressed at the same time. When the driving frame 501 moves, it first stops conveying the pipe fittings, and at the same time, the control frame 502 moves away from the inner side of the driving ring 201, so as to pull the pull block 405 to move the locking column 403 away from the opening on the mounting ring 103, thereby releasing the fixed connection between the driving ring 201 and the mounting ring 103. The friction between the driving ring 201 and the mounting ring 103 drives the driving ring 201 to continue to rotate until the pull block 405 is clamped in the clamping groove 504, and the position of the driving ring 201 is fixed, so that the driving ring 201 and the mounting ring 103 move relative to each other. When the driving ring 201 and the mounting ring 103 move relative to each other, the cooperation between the inclined groove 203 and the driving column 109 drives the sealing frame 107 to rise and fall on the outer wall of the nozzle 105, so that the cleaning needle frame 108 penetrates the spray hole 106 to clean the spray hole 106, and pushes the solidified paint in the spray hole 106 out of the nozzle 105, thereby effectively preventing the nozzle 105 from being blocked, and there is no need to manually clean the nozzle 105 one by one, thereby improving the cleaning efficiency.

[0072] like Figure 2 , 5 As shown in , 7, in this embodiment, a mounting frame 601 is slidably disposed on one side of the frame 101, a cleaning ring 602 is rotatably disposed on the mounting frame 601, a cleaning brush 603 is disposed at the end of the cleaning ring 602, and the driving frame 501 is connected to the cleaning ring 602 through a propulsion assembly, and the propulsion assembly converts the swing of the driving frame 501 into driving the cleaning ring 602 to slide out until the cleaning brush 603 contacts the ends of the multiple groups of nozzles 105. The propulsion assembly includes a propulsion column 406 disposed on the pull block 405, and an inclined track 604 is disposed on the cleaning ring 602, and the propulsion column 406 is slidably clamped in the inclined track 604.

[0073] In the initial state, the cleaning ring 602 is in a retracted state and rotates along with the rotation of the driving frame 501 under the cooperation and limitation of the propulsion column 406 and the inclined track 604. The mounting frame 601 does not move. In the process of moving the driving frame 501 to move the pull block 405 upward, the mounting frame 601 and the cleaning ring 602 are driven to translate as a whole through the cooperation of the propulsion column 406 and the inclined track 604 until the cleaning ring 602 extends between the multiple groups of nozzles 105. The nozzles 105 move relative to the annular cleaning brush 603 during the movement. The paint residue pushed out by the cleaning needle holder 108 on the nozzles 105 is removed by the cleaning brush 603 to improve the effect of cleaning the nozzles 105.

[0074] Specific usage and beneficial effects of the present invention:

[0075] When the device is in use, the pipe is transported to the support ring 102 through the conveying mechanism, and the paint is supplied to the multiple groups of nozzles 105 through the external feeding system, and sprayed to the surface of the pipe through the spray hole 106. In the process of spraying, the installation ring 103 can be controlled to rotate back and forth by the power mechanism, so that the paint spraying is more uniform. At the same time, the power mechanism provides power to the conveying mechanism to transport the pipe to continuously spray the pipe. If the spray hole 106 is blocked during the spraying process, the drive frame 501 can be moved downward. During the movement, the drive frame 501 drives the multiple groups of cleaning needle racks 108 to rise and fall in the spray hole 106 through the driving mechanism to clear the spray hole 106, so that the nozzle 105 cleaning work can be completed quickly without stopping the entire device, effectively preventing the nozzle 105 from being blocked, and no manual cleaning is required, which reduces the labor cost of the staff and improves the spraying efficiency.

[0076] When the device is in use, the driving motor 301 drives the first synchronous wheel 303 to rotate, and drives the second synchronous wheel 307 to rotate through the tension wheel 304. During the rotation process, the second synchronous wheel 307 drives one group of conveying rollers 702 to rotate through the cooperation of the first bevel gear 309 and the second bevel gear 701, and drives the other group of conveying rollers 702 to rotate in the opposite direction under the action of the reversing belt 703. During the rotation process, the two groups of conveying rollers 702 control the conveying rollers 706 to rotate through the belt transmission mechanism 705 to convey the pipe. In the process of cleaning the nozzle 105 by controlling the movement of the driving frame 501, the driving frame 501 moves downward to press the tension wheel 304, and the slider 305 on one side of the tension wheel 304 compresses the first elastic member 306, so that the synchronous belt 308 is relaxed, and the conveying roller 706 stops rotating at this time, so that the continuous transmission of the pipe is avoided during the cleaning process of the nozzle 105, resulting in gaps in the spraying, and there is no need to control the start and stop of the pipe transportation separately, which further improves the efficiency of the spraying.

[0077] When the device is in use, the pulling block 405 and the pushing column 406 follow the movement of the mounting ring 103, so that the cleaning ring 602 rotates accordingly. In the process of cleaning the nozzle 105 by moving the driving frame 501, the control frame 502 at one end of the driving frame 501 pulls the pulling block 405 upward. In the process of moving the pulling block 405, the cleaning ring 602 is controlled to slide along its axis through the cooperation of the pushing column 406 and the inclined track 604 until the cleaning brush 603 extends out and contacts the ends of the multiple groups of nozzles 105, thereby removing impurities pushed out by the cleaning needle frame 108, further preventing impurities from adhering to the nozzle 105, and improving the cleaning effect.

[0078] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments. On the basis of the present invention, some modifications or improvements can be made thereto, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
