Description

Technical Field

[0001] This utility model relates to the field of powder recovery pipeline connection technology, specifically a quick-connect joint structure for powder recovery pipelines used for color change and cleaning. Background Technology

[0002] In processes such as powder coating, it is often necessary to spray powders of different colors. During color changes, the powder recovery pipeline needs to be cleaned to prevent cross-contamination between different colored powders.

[0003] In processes involving powder recycling, such as powder coating, the existing powder recycling pipeline joint structure has significant drawbacks. Its disassembly and installation are extremely cumbersome, often requiring workers to perform multiple complex operations, such as repeatedly tightening numerous bolts and performing precise alignment. This not only consumes a significant amount of time but also requires substantial manpower. When frequently changing colors, this inefficient operation severely impacts production continuity, leading to a substantial reduction in overall production efficiency.

[0004] Therefore, it is necessary to provide a quick-connect coupling structure for powder recovery pipelines used for color change and cleaning to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a quick-connect coupling structure for a powder recovery pipeline used for color change and cleaning, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-connect fitting structure for a powder recovery pipeline used for color-changing cleaning, comprising:

[0008] A first pipe and a second pipe are connected. An annular box is fixedly installed on the outer wall of one end of the first pipe, and an annular connector is fixedly installed on the outer wall of one end of the second pipe. A number of positioning rods are evenly spaced and uniformly arranged on one side of the annular connector. An insertion hole corresponding to the position and number of the positioning rods is opened on one side of the annular box, and the insertion hole is slidably inserted into the positioning rod. A positioning mechanism corresponding to the position and number of the positioning rods is provided inside the annular box. An annular sealing cover is fixedly installed on the other side of the annular box, and an operating mechanism is provided on the annular sealing cover.

[0009] Preferably, one end of the second pipe is provided with a connecting groove, and one end of the first pipe is fixedly installed with a connecting end that is adapted to the connecting groove, and the connecting end is inserted into the connecting groove. A sealing ring is provided at the connection between the connecting end and the inner wall of the connecting groove.

[0010] Preferably, the positioning mechanism includes a fixed frame, which is fixedly installed inside the annular box. A limit rod is slidably inserted into the bottom of the fixed frame. Slide grooves are provided on both sides of the inner wall of the fixed frame. A symmetrically distributed slider is fixedly installed at the top of the limit rod, and the slider is slidably installed on the slide groove at the corresponding position. A spring is fixedly installed inside the slide groove at the top of the slider. A positioning hole is provided on the positioning rod, and the positioning hole is engaged with the limit rod.

[0011] Preferably, the operating mechanism includes an annular rotating plate, which is rotatably mounted on one side of the annular sealing cover. The inner surface of the annular rotating plate is located inside the annular sealing cover. A through groove corresponding to the position and number of limiting rods is opened on the other side of the annular box. A limiting block is fixedly installed at the top of the limiting rod. An external rod is fixedly installed on the limiting block, and one end of the external rod passes through the through groove and extends into the interior of the annular sealing cover. An arc-shaped movable block corresponding to the position and number of the external rods is fixedly installed on the inner surface of the annular rotating plate.

[0012] Preferably, a number of anti-slip strips are evenly and uniformly bonded to the outer surface of the annular rotating plate.

[0013] Preferably, the contact surface between the arc-shaped movable block and the external rod is an arc-shaped surface.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model utilizes the combined use of a first pipe, a second pipe, an annular connector, a positioning rod, an insertion hole, an annular housing, an annular sealing cover, an arc-shaped movable block, an annular rotating plate, a positioning mechanism, a positioning hole, a through groove, an external rod, a sliding groove, a fixing frame, a spring, a slider, a limiting rod, and a limiting block. During use, the insertion of the positioning rod into the insertion hole ensures the accuracy of the connection between the first and second pipes. The positioning mechanism's position is adjusted via an operating mechanism to lock the positioning rod inside the annular housing, ensuring connection stability. The entire assembly and disassembly process only requires operating the annular rotating plate to fix and unlock the positioning rod, which is simpler than traditional bolt fixing methods and effectively ensures production efficiency in scenarios with frequent color changes.

[0016] 2. This utility model utilizes the combined use of a connecting end and a connecting groove. During the assembly of the first and second pipes, the connecting end of the first pipe is precisely inserted into the connecting groove of the second pipe's mounting end. This insertion-and-fitting method significantly enhances the structural stability of the connection between the first and second pipes, ensuring that the pipe connection will not easily loosen or shift during processes such as powder recovery. Furthermore, a sealing ring is installed at the connection between the connecting end and the connecting groove. This sealing ring forms a reliable sealing barrier at the pipe connection, effectively preventing powder leakage. This not only avoids material waste caused by powder leakage but also significantly reduces the risk of environmental pollution from powder scattering, making the production process more environmentally friendly and efficient.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 One embodiment provided by this utility model:

[0028] A quick-connect fitting structure for a powder recovery pipeline used for color-changing cleaning, comprising:

[0029] The first pipe 1 and the second pipe 2 are connected by a ring-shaped box 7 fixedly installed on the outer wall of one end of the first pipe 1 and a ring-shaped connector 3 fixedly installed on the outer wall of one end of the second pipe 2. A number of positioning rods 4 are evenly spaced and uniformly arranged on one side of the ring-shaped connector 3. A hole 6 corresponding to the position and number of the positioning rods 4 is opened on one side of the ring-shaped box 7, and the hole 6 is slidably inserted into the positioning rods 4. A positioning mechanism 12 corresponding to the position and number of the positioning rods 4 is set inside the ring-shaped box 7. An annular sealing cover 8 is fixedly installed on the other side of the ring-shaped box 7, and an operating mechanism is set on the annular sealing cover 8.

[0030] One end of the second pipe 2 is provided with a connecting groove 9, and one end of the first pipe 1 is fixedly installed with a connecting end 5 that is compatible with the connecting groove 9. The connecting end 5 is inserted into the connecting groove 9, and a sealing ring is provided at the connection between the connecting end 5 and the inner wall of the connecting groove 9. The insertion and matching method between the connecting end 5 and the connecting groove 9 can significantly enhance the structural stability of the connection between the first pipe 1 and the second pipe 2, and ensure that the pipe connection will not easily loosen or shift during powder recovery and other operations.

[0031] In one embodiment, the positioning mechanism 12 includes a fixing frame 17, which is fixedly installed inside the annular box 7. A limiting rod 20 is slidably inserted into the bottom of the fixing frame 17. Slide grooves 16 are provided on both sides of the inner wall of the fixing frame 17. A symmetrically distributed slider 19 is fixedly installed at the top of the limiting rod 20, and the slider 19 is slidably installed on the corresponding slide groove 16. A spring 18 is fixedly installed inside the slide groove 16 at the top of the slider 19. A positioning hole 13 is provided on the positioning rod 4, and the positioning hole 13 is engaged with the limiting rod 20, realizing the self-locking effect of the positioning rod 4 and ensuring the connection stability of the pipeline.

[0032] In one preferred embodiment, the operating mechanism includes an annular rotating plate 11, which is rotatably mounted on one side of the annular sealing cover 8. The inner surface of the annular rotating plate 11 is located inside the annular sealing cover 8. The other side of the annular housing 7 is provided with a through groove 14 corresponding to the position and number of the limiting rods 20. A limiting block 21 is fixedly installed at the top of the limiting rod 20. An external rod 15 is fixedly installed on the limiting block 21, and one end of the external rod 15 passes through the through groove 14 and extends into the interior of the annular sealing cover 8. An arc-shaped movable block 10 corresponding to the position and number of the external rods 15 is fixedly installed on the inner surface of the annular rotating plate 11 to facilitate the operation of the position of the limiting rod 20.

[0033] In one embodiment, several anti-slip strips are evenly and uniformly bonded to the outer surface of the annular rotating plate 11, which increases the friction between the hand and the annular rotating plate 11, making the rotation operation more labor-saving and stable, and facilitating workers to quickly complete the disassembly and assembly of pipes.

[0034] In one preferred embodiment, the contact surface between the arc-shaped movable block 10 and the external rod 15 is an arc-shaped surface, which allows the two to make a closer contact, reduces frictional loss, and makes the arc-shaped movable block 10 push the external rod 15 to move more smoothly.

[0035] The working principle of this utility model is as follows: All parts not mentioned in this device are the same as or can be implemented using existing technology. During use, in the assembly process, firstly, rotate the annular rotating plate 11 on the outside of the annular sealing cover 8. The rotation of the annular rotating plate 11 causes the arc-shaped movable block 10 to shift. The arc-shaped movable block 10 applies a force to the external rod 15, pushing the external rod 15 to slide within the through groove 14. The movement of the external rod 15 causes the limiting block 21 to move synchronously, thereby causing the limiting rod 20 to move. Simultaneously, the movement of the limiting rod 20 causes the slider 19 to slide on the sliding groove 16 and compresses the spring 18. When the limiting rod 20 moves to the designated position, the installation ends of the first pipe 1 and the second pipe 2 are spliced. At this time, the positioning rod 4 on the annular connector 3 will be inserted into the insertion hole 6 on the annular box 7, and the positioning rod 4, after entering the annular box 7, corresponds to the position of the limiting rod 20. Subsequently, the limiting position of the annular rotating plate 11 is released, and the elastic restoring action of the spring 18 drives the slider 19 to reset, thereby causing the limiting rod 20 to reset and engage with the positioning hole 13 on the positioning rod 4, thus securing the positioning rod 4 within the annular housing 7 and completing the installation of the first pipe 1 and the second pipe 2. During disassembly, rotating the annular rotating plate 11 causes the limiting rod 20 to disengage from the positioning hole 13, releasing the limiting position of the positioning rod 4 within the annular housing 7, allowing the first pipe 1 and the second pipe 2 to separate. The positioning rod 4 is then pulled out of the annular housing 7, completing the disassembly operation. During pipe use, the insertion of the positioning rod 4 into the insertion hole 6 ensures the accuracy of the connection between the first pipe 1 and the second pipe 2. By adjusting the position of the positioning mechanism 12 through the operating mechanism, the positioning rod 4 entering the annular housing 7 is locked, ensuring the stability of the connection. The entire disassembly and assembly process only requires operating the annular rotating plate 11 to fix and unlock the positioning mechanism 12 for the positioning rod 4, which is simpler than the traditional bolt fixing method and can effectively ensure production efficiency in scenarios with frequent color changes.

[0036] During the assembly of the first pipe 1 and the second pipe 2, the connecting end 5 of the first pipe 1 is precisely inserted into the connecting groove 9 of the mounting end of the second pipe 2. This insertion-fitting method between the connecting end 5 and the connecting groove 9 significantly enhances the structural stability of the connection between the first pipe 1 and the second pipe 2, ensuring that the pipe connection will not easily loosen or shift during processes such as powder recovery. Furthermore, a sealing ring is installed at the connection between the connecting end 5 and the connecting groove 9. This sealing ring forms a reliable sealing barrier at the pipe connection, effectively preventing powder leakage from the connection. This not only avoids material waste caused by powder leakage but also significantly reduces the risk of pollution to the surrounding environment from powder scattering, making the production process more environmentally friendly and efficient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
