The use of slewing bearings and Glyd rings makes distributor maintenance complex, requiring a significant investment of manpower and time, increasing operating costs and operational difficulty. Moreover, their short service life and frequent replacement of wear parts not only increase equipment operating costs but also lead to increased equipment downtime, affecting production efficiency.

A wear-resistant component, replacing a traditional rotary bearing, is provided between the fixed part and the rotating part at the rotary contact surface of the two to reduce wear during relative rotation. Furthermore, the rotating part includes a distribution block, fluid holes, positioning bolts, a connecting shaft, a distribution disc, and distribution holes; the distribution disc is bolted to the rotation center of the planetary turntable; a connecting shaft is fixedly installed inside the distribution disc; the top of the distribution disc is connected to the distribution block via the connecting shaft; a threaded hole is provided inside the distribution block, and a positioning bolt is installed in the threaded hole to connect it to the connecting shaft; several fluid holes are provided in the distribution block; several distribution holes corresponding one-to-one with the fluid holes and communicating with each other are provided inside the distribution disc; each distribution hole is externally connected to an independent nozzle assembly. Furthermore, sealing rings are provided between the connecting shaft and the distribution disc and distribution block for sealing; Furthermore, the fixing part includes a pipe, an inner tube, a set screw, a connecting block, a sealing cap, a connecting plate, and a mask disc. The pipe is used to connect to the machine's piping system, allowing fluid to enter. The inner tube is fixedly connected to the inside of the four mobile phone pipes by a set screw. The top of the distribution block has an installation groove. The inside of the installation groove is equipped with a mask disc, which has several cuts that mate with the fluid holes. The mask disc is fixed relative to the bottom of the inner tube. The top of the distribution block is sequentially connected to the connecting plate, the connecting block, and the sealing cap, combined with a sealing ring, to form a sealing chamber to seal the inner tube. A sealing gasket is provided between the top cap and the pipe. Furthermore, the wear-resistant component includes a wear-resistant block and a wear-resistant disc; the wear-resistant block is embedded in the inner ring of the connecting block and is tightly fitted with the inner tube; the wear-resistant disc is disposed between the MASK disc and the distribution block; the wear-resistant disc and the distribution block are fixedly connected, and several springs are fixedly disposed between the inner tube and the MASK disc; the MASK disc and the distribution disc are fitted together by the pressure of the springs at both ends.

Detailed Implementation

[0008] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in detail below: This utility model discloses a chemical reagent rotary dispenser, such as... Figure 1As shown, a chemical reagent rotary dispenser includes a fixed part 100 for fixed connection to a machine tool, a rotating part 200 for connection to a planetary turntable 300 and rotatable relative to the fixed part 100, and a nozzle assembly arranged in a circumferential array on the outside of the planetary turntable 300. A wear-resistant component, replacing a traditional rotary bearing, is disposed between the fixed part 100 and the rotating part 200 at their rotational contact surface to reduce wear during relative rotation. In this embodiment, the wear-resistant component, replacing a traditional rotary bearing, is disposed at the rotational contact surface between the fixed part 100 and the rotating part 200. When the rotating part 200 rotates relative to the fixed part 100... During rotation, the wear-resistant component bears the friction between the two, reducing wear caused by direct contact. The wear-resistant component includes a wear-resistant block 5 and a wear-resistant disc 10. The wear-resistant block 5 is embedded in the inner ring of the connecting block 4 and fits tightly with the inner tube 2. The wear-resistant disc 10 is placed between the MASK disc 7 and the distribution block 8. They play a buffering and protective role during rotation. The combination of traditional slewing bearings and Glyd rings is complicated to maintain and has a short service life. The use of the wear-resistant component simplifies the structure and reduces the difficulty of maintenance. At the same time, the wear-resistant component can effectively reduce wear during relative rotation, extend the service life of the distributor, and improve the reliability and stability of the equipment. like Figure 2 , 3As shown, the rotating part 200 includes a distribution block 8, fluid holes 9, positioning bolts 11, a connecting shaft 12, a distribution disk 13, and distribution holes 14. The distribution disk 13 is bolted to the rotation center of the planetary turntable 300. The connecting shaft 12 is fixedly installed inside the distribution disk 13. The top of the distribution disk 13 is connected to the distribution block 8 via the connecting shaft 12. The distribution block 8 has a threaded hole inside, and the positioning bolts 11 are installed in the threaded hole to connect it to the connecting shaft 12. The distribution block 8 has several fluid holes 9. The distribution disk 13 has several distribution holes 14 that correspond one-to-one with the fluid holes 9 and are interconnected. Each distribution hole 14 is connected to an independent nozzle assembly. In this embodiment, the distribution disk 13 is bolted to the rotation center of the planetary turntable 300, the connecting shaft 12 is fixed inside the distribution disk 13, and the top of the distribution disk 13 is connected to the connecting shaft 12. The distribution block 8 is connected via a connecting shaft 12. The distribution block 8 has a threaded hole inside and is connected to the connecting shaft 12 via a positioning bolt 11, ensuring a stable connection between the distribution block 8 and the connecting shaft 12. The distribution block 8 has several fluid holes 9, and the distribution disc 13 has several distribution holes 14 that correspond one-to-one with and communicate with the fluid holes 9. When the chemical agent enters the inner tube 2 from the pipe 1 of the fixed part 100, then enters the fluid hole 9 through the cut of the MASK disc 7, and is then distributed to each external nozzle assembly through the distribution holes 14, this structural design allows the chemical agent to be orderly transferred from the fixed part 100 to the rotating part 200 and evenly distributed to each nozzle assembly through the distribution holes 14, achieving precise chemical agent distribution. Furthermore, the components are connected by bolts and positioning bolts 11, facilitating installation and disassembly, and making maintenance and replacement convenient. like Figure 2 , 3 As shown, sealing rings are provided between the connecting shaft 12 and the distribution disk 13 and the distribution block 8 for sealing. In this embodiment, sealing rings are provided between the connecting shaft 12 and the distribution disk 13 and the distribution block 8 for sealing. The sealing rings can prevent chemical agents from leaking from the connection between the connecting shaft 12 and the distribution disk 13 and the distribution block 8 during the transmission process, ensuring the airtightness of the chemical agent transmission. This avoids the leakage of chemical agents, which not only improves the utilization rate of chemical agents, but also prevents the damage to equipment and the environment caused by the leakage of agents, and also ensures the normal operation of the distributor. like Figure 2 , 3As shown, the fixing part 100 includes a pipe 1, an inner tube 2, a set screw 3, a connecting block 4, a sealing cap 41, a connecting plate 6, and a mask plate 7. The pipe 1 is used to connect to the machine's pipeline and allow fluid to enter. The inner tube 2 is fixedly connected to the inside of the pipe 1 by the set screw 3. The top of the distribution block 8 has an installation groove. The inside of the installation groove is equipped with a mask plate 7, which has several cuts that cooperate with the fluid holes 9. The mask plate 7 is fixed relative to the bottom of the inner tube 2. The top of the distribution block 8 is connected to the connecting plate 6, the connecting block 4, and the sealing cap 41 in sequence with a sealing ring to form a sealing chamber to seal the inner tube 2. A sealing gasket is provided between the top cap and the pipe 1. In this embodiment, the pipe 1 is used to connect to the machine's pipeline and allow fluid to enter. The inner tube 2 is fixed inside the pipe 1 by the set screw 3 to ensure the relative fixation of the inner tube 2 and the pipe 1. The installation groove on the top of the distribution block 8 is equipped with a mask plate 7, which has several cuts that cooperate with the fluid holes 9. Chemical reagents enter the fluid port 9 through the cut in the MASK disc 7 from the inner tube 2. The top of the distribution block 8 is connected in sequence with the connecting plate 6, connecting block 4, and sealing cover 41, which, together with the sealing ring, form a sealing chamber to seal the inner tube 2 and prevent chemical reagent leakage. A sealing gasket is set between the top cover and the pipe 1 to further enhance the sealing effect. This structural design ensures the stable transmission of chemical reagents from the machine piping to the rotating part 200. At the same time, the setting of the sealing chamber and sealing gasket effectively prevents chemical reagent leakage and improves the safety and reliability of the equipment. like Figure 2 , 3 As shown, the wear-resistant component includes a wear-resistant block 5 and a wear-resistant disc 10. The wear-resistant block 5 is embedded in the inner ring of the connecting block 4 and is tightly fitted with the inner tube 2. The wear-resistant disc 10 is disposed between the mask disc 7 and the distribution block 8. The wear-resistant disc 10 and the distribution block 8 are fixedly connected, and several springs are fixedly installed between the inner tube 2 and the mask disc 7. The pressure of the springs at both ends controls the fit between the mask disc 7 and the distribution disc 13. Both the wear-resistant disc 10 and the wear-resistant block 5 are made of PEEK material. In this embodiment, both the wear-resistant disc 10 and the wear-resistant block 5 are made of PEEK material, which has excellent wear resistance and chemical resistance. The device exhibits excellent corrosion resistance and mechanical properties, maintaining good performance even under prolonged friction and contact with chemical agents. Several springs are fixedly installed between the inner tube 2 and the MASK disc 7. The pressure of the springs at both ends controls the fit between the MASK disc 7 and the distribution disc 13, ensuring that the chemical agent can smoothly enter the distribution hole 14 of the distribution disc 13 from the cut of the MASK disc 7. The wear-resistant disc 10 and wear-resistant block 5 made of PEEK material extend the service life of the wear-resistant components and reduce the replacement frequency. The springs ensure a tight fit between the MASK disc 7 and the distribution disc 13, improving the stability and accuracy of chemical agent transmission. like Figure 2 , 3As shown, the nozzle assembly includes a fluid conduit 15, a nozzle support 16, and a nozzle 17; one end of the fluid conduit 15 is threaded onto each distribution hole 14; the nozzle support 16 is bolted to the outer wall of the planetary disk 300; the nozzle 17 is bolted onto the inside of the nozzle support 16; the nozzle 17 is connected to the other end of the fluid conduit 15; the fluid conduit 15, nozzle support 16, and nozzle 17 are all made of stainless steel; in this embodiment, one end of the fluid conduit 15 is threaded onto each distribution hole 14, and the outer wall of the planetary disk 300 is bolted to the other end of the fluid conduit 15. The nozzle bracket 16 is bolted together, and the nozzle 17 is installed inside the nozzle bracket 16 by bolts. The nozzle 17 is connected to the other end of the fluid pipeline 15. The chemical agent is transmitted from the distribution hole 14 through the fluid pipeline 15 to the nozzle 17, and then sprayed out from the nozzle 17. This structural design makes the installation and disassembly of the nozzle assembly convenient, and facilitates replacement and maintenance. At the same time, the fluid pipeline 15, the nozzle bracket 16, and the nozzle 17 are all made of stainless steel. Stainless steel has good corrosion resistance and can adapt to the corrosive environment of chemical agents, thus extending the service life of the nozzle assembly. like Figure 2 , 3 As shown, an anti-rotation device 18 is provided on the outside of the pipe 1; it is used to connect with the machine and prevent the fixed part 100 from rotating. In this embodiment, the anti-rotation device 18 is provided on the outside of the pipe 1 to connect with the machine and prevent the fixed part 100 from rotating. When the rotating part 200 rotates relative to the fixed part 100, the anti-rotation device 18 can fix the fixed part 100, ensuring the normal operation of the distributor. It avoids the rotation of the fixed part 100, ensures the stability of the chemical agent transmission path, and improves the working accuracy and reliability of the distributor. The implementation principle of this utility model embodiment is as follows: In use, the present invention is first connected to the pipe 1 of the fixing part 100 and the machine tool pipeline, and the fluid is connected to enter; at this time, the chemical agent enters the pipe 1 through the machine tool pipeline, and then passes through the inner tube 2 fixed by the set screw 3; in the fixing part 100, the cut inside the MASK disk 7 corresponds to the fluid hole 9 in the distribution block 8, and the chemical agent reaches the position of the MASK disk 7 through the inner tube 2, and enters the fluid hole 9 of the distribution block 8 through the cut; As the planetary turntable 300 rotates, the rotating part 200 begins to rotate relative to the fixed part 100; the distribution plate 13 is bolted to the rotation center of the planetary turntable 300, and a connecting shaft 12 is fixed inside it, which is connected to the distribution block 8 at the top; due to the presence of wear-resistant components, the wear between the fixed part 100 and the rotating part 200 during rotation is reduced, ensuring long-term stable operation. When the dispensing block 8 rotates together with the rotating part 200, its internal fluid hole 9 remains in communication with the dispensing hole 14 in the dispensing disk 13. Chemical agents flow from the fluid hole 9 into the corresponding dispensing hole 14 and are transmitted to the nozzle 17 on the nozzle holder 16 via the threaded fluid conduit 15. Each dispensing hole 14 is externally connected to an independent nozzle assembly, thereby achieving multi-point uniform dispensing. Ultimately, the chemical agent is precisely sprayed through the stainless steel fluid pipeline 15, nozzle support 16 and nozzle 17 to complete the continuous or intermittent distribution to the target area; the whole process realizes efficient, accurate and low-maintenance automated liquid distribution, solving the problems of easy damage and complicated maintenance of traditional rotary bearings.
