Description

Technical Field

[0001] This utility model relates to the field of nozzle cooling technology, and in particular to a nozzle cooling mechanism for a floating bushing. Background Technology

[0002] In many industrial equipment, such as engines and injection molding machines, the nozzle temperature rises sharply during operation due to the scouring and friction of high-speed fluid and the generation of internal heat. If the nozzle is not cooled in a timely and effective manner, it will not only affect the nozzle's spraying accuracy and stability, but also shorten the nozzle's service life and may even lead to equipment failure.

[0003] Currently, existing nozzle cooling mechanisms for floating bushings have certain limitations in terms of cooling efficiency and structural stability, and their cooling effect is poor. During long-term use, they are prone to seal failure, which affects cooling performance. Therefore, we propose a nozzle cooling mechanism for floating bushings. Utility Model Content

[0004] The purpose of this invention is to provide a nozzle cooling mechanism for floating bushings, which solves the problems of existing nozzle cooling mechanisms for floating bushings having certain limitations in terms of cooling efficiency and structural stability, poor cooling effect, and easy sealing failure during long-term use, thus affecting cooling performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nozzle cooling mechanism for a floating bushing, comprising a mounting base and a nozzle assembly, the nozzle assembly being fixedly installed on the left side of the mounting base, a floating bushing device being provided on the outer side of the nozzle assembly, a cooling device being provided inside the floating bushing device and on the surface of the mounting base, the floating bushing device comprising an inner bushing and an outer bushing, the inner bushing being fitted onto the outer surface of the nozzle assembly, and the outer bushing being fitted onto the outer surface of the inner bushing, the cooling device comprising a coolant storage tank fixedly installed on the right side of the mounting base, the coolant storage tank being connected to an output pipe and a cooling pipe via a circulation pump, and the cooling pipe being connected to a radiator and a return pipe via a connecting pipe.

[0006] As a preferred embodiment, the cooling pipe is spirally arranged and fixedly installed on the outer circumferential surface of the inner liner. The circulating pump is fixedly installed on the side of the coolant storage tank near the cooling pipe via a motor mount. One end of the output pipe is fixedly installed at the output end of the circulating pump, and the other end is fixedly connected to the cooling pipe.

[0007] As a preferred embodiment, the radiator is fixedly installed on the right end of the surface of the mounting base and located on one side of the coolant storage tank. One end of the connecting pipe is fixedly connected to the cooling pipe, and the other end is fixedly connected to the input end of the radiator.

[0008] As a preferred embodiment, one end of the return pipe is fixedly connected to the output end of the radiator, and the other end is fixedly connected to the coolant storage tank.

[0009] As a preferred embodiment, a thin lubricating layer is provided between the inner wall of the inner bushing and the outer surface of the nozzle assembly, and a sealed annular cavity is formed between the inner bushing and the outer bushing. Sealing annular grooves are provided on the outer surfaces of the upper and lower ends of the inner bushing and the inner surfaces of the upper and lower ends of the outer bushing. A first sealing ring is engaged between the two sets of sealing annular grooves at the upper end, and a second sealing ring is engaged between the two sets of sealing annular grooves at the lower end.

[0010] As a preferred embodiment, multiple sets of first fixing blocks and second fixing blocks are fixedly installed on the outer surfaces of the upper and lower ends of the inner bushing and the inner surfaces of the upper and lower ends of the outer bushing, respectively. Spring columns are fixedly installed between the multiple sets of first fixing blocks and the multiple sets of second fixing blocks. An installation ring is fixedly installed at the bottom of the outer bushing, and a number of installation holes with equal spacing are opened on the surface of the installation ring.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting up a cooling device, the coolant storage tank, circulation pump and spiral cooling pipe work together to circulate the coolant outside the inner bushing, efficiently remove the heat from the nozzle assembly and reduce the temperature of the components. The spiral cooling pipe is set outside the inner bushing to increase the contact area of ​​the coolant and improve the cooling efficiency. The radiator is fixed at the right end of the mounting base next to the coolant storage tank. The connecting pipe and return pipe form a loop, so that the coolant is cooled by the radiator and then flows back to the storage tank, maintaining the temperature of the cooling system and ensuring the continuous and reliable cooling effect.

[0013] 2. By setting up a floating bushing device and a lubricating layer on the inner wall of the inner bushing, the relative motion friction between the inner bushing and the outer surface of the nozzle assembly is reduced, wear is reduced, and the life of the component is extended. The inner bushing and the outer bushing form a sealed annular chamber through the sealing annular groove, the first sealing ring, and the second sealing ring, which ensures the normal operation of the cooling system and blocks external impurities. The two are connected by multiple sets of first fixed blocks, second fixed blocks, and spring columns. The spring columns provide elastic support, allowing the inner bushing to float appropriately, compensating for the working vibration and displacement of the nozzle assembly, and enhancing structural stability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Please see the appendix Figure 1 - Appendix Figure 2 and appendix Figure 5 A nozzle cooling mechanism for a floating bushing includes a mounting base 1 and a nozzle assembly 2. The nozzle assembly 2 is fixedly mounted on the left side of the mounting base 1. A floating bushing device 3 is provided on the outer side of the nozzle assembly 2. A cooling device 4 is provided inside the floating bushing device 3 and on the surface of the mounting base 1. The floating bushing device 3 includes an inner bushing 301 and an outer bushing 302. The inner bushing 301 is fitted onto the outer surface of the nozzle assembly 2, and the outer bushing 302 is fitted onto the outer surface of the inner bushing 301. The cooling device 4 includes a coolant storage tank 401 fixedly mounted on the right side of the surface of the mounting base 1. The coolant storage tank 401 is connected to an output pipe 403 and a cooling pipe 404 through a circulation pump 402. The cooling pipe 404 is connected to a radiator 406 and a return pipe 407 through a connecting pipe 405. The mounting base 1 serves as a basic support component, providing a stable mounting position for the nozzle assembly 2, and also creating conditions for the installation layout of the cooling device 4 and the floating bushing device 3, ensuring the stability of the entire mechanism.

[0022] The cooling pipe 404 is spirally arranged and fixedly installed on the outer circumferential surface of the inner bushing 301. The circulating pump 402 is fixedly installed on the side of the coolant storage tank 401 near the cooling pipe 404 via a motor mount. One end of the output pipe 403 is fixedly installed on the output end of the circulating pump 402, and the other end is fixedly connected to the cooling pipe 404. The spiral arrangement of the cooling pipe 404 on the outside of the inner bushing 301 greatly increases the contact path between the coolant and the inner bushing 301. Combined with the power transmission of the circulating pump 402, it significantly improves the heat exchange efficiency and enhances the cooling effect.

[0023] The radiator 406 is fixedly installed on the right side of the surface of the mounting base 1 and located on one side of the coolant storage tank 401. One end of the connecting pipe 405 is fixedly connected to the cooling pipe 404, and the other end is fixedly connected to the input end of the radiator 406. The radiator 406 is fixed at a specific position on the surface of the mounting base 1, and together with the connecting pipe 405 and the return pipe 407, it forms a coolant heat dissipation circulation link, which accurately and efficiently dissipates the heat carried by the coolant and maintains the temperature stability of the cooling system.

[0024] One end of the return pipe 407 is fixedly connected to the output end of the radiator 406, and the other end is fixedly connected to the coolant storage tank 401. As a key part of the coolant circulation loop, the return pipe 407 ensures that the coolant cooled by the radiator 406 can flow smoothly back to the coolant storage tank 401, ensuring a continuous supply of coolant.

[0025] Specifically, the coolant storage tank 401, circulation pump 402, and spiral cooling pipe 404 work together to circulate the coolant outside the inner bushing 301 of the floating bushing device 3, effectively carrying away the heat generated by the nozzle assembly 2 and effectively reducing the component temperature. The cooling pipe 404 is fixedly installed on the outer circumferential surface of the inner bushing 301 and is arranged in a spiral shape to make full use of space. It increases the contact area between the coolant and the inner bushing 301 within the limited installation space, thereby improving cooling efficiency. The radiator 406 is fixedly installed on the right end of the mounting base 1 and located on one side of the coolant storage tank 401. The connecting pipe 405 and the return pipe 407 form a circulation loop to ensure that the coolant returns to the coolant storage tank 401 after being effectively cooled by the radiator 406, maintaining the temperature stability of the cooling system and ensuring a continuous and reliable cooling effect.

[0026] Please see the appendix Figure 1 - Appendix Figure 4A thin lubricating layer is provided between the inner wall of the inner bushing 301 and the outer surface of the nozzle assembly 2. A sealed annular cavity is formed between the inner bushing 301 and the outer bushing 302. Sealing annular grooves 303 are provided on the outer surfaces of the upper and lower ends of the inner bushing 301 and the inner surfaces of the upper and lower ends of the outer bushing 302. A first sealing ring 304 is engaged between the two sets of sealing annular grooves 303 at the upper end, and a second sealing ring 305 is engaged between the two sets of sealing annular grooves 303 at the lower end. The inner bushing 301 and the outer bushing 302 form a sealing structure through the sealing annular grooves 303, the first sealing ring 304 and the second sealing ring 305, which prevents external impurities from entering, protects the internal structure and maintains the sealing performance of the cooling system.

[0027] Multiple sets of first fixing blocks 307 and second fixing blocks 308 are fixedly installed on the outer surfaces of the upper and lower ends of the inner bushing 301 and the inner surfaces of the upper and lower ends of the outer bushing 302, respectively. Spring pillars 309 are fixedly installed between the multiple sets of first fixing blocks 307 and multiple sets of second fixing blocks 308. An installation ring 306 is fixedly installed at the bottom of the outer bushing 302, and several installation holes with equal spacing are opened on the surface of the installation ring 306. The installation ring 306 and the evenly distributed installation holes at the bottom of the outer bushing 302 facilitate the fixed connection with the mounting base 1 by bolts or other connecting parts. At the same time, the inner bushing 301 and the outer bushing 302 are connected by the first fixing blocks 307, the second fixing blocks 308 and the spring pillars 309, giving the inner bushing 301 a floating buffer function.

[0028] Specifically, the lubricating layer between the inner wall of the inner bushing 301 and the outer surface of the nozzle assembly 2 can effectively reduce friction during relative movement, reduce wear, and improve the service life of the components. At the same time, the inner bushing 301 and the outer bushing 302 form a sealed annular chamber through the sealing annular groove 303, the first sealing ring 304, and the second sealing ring 305, ensuring the normal operation of the cooling system and preventing external impurities from entering. The inner bushing 301 and the outer bushing 302 are connected by multiple sets of first fixing blocks 307, second fixing blocks 308, and spring pillars 309. The spring pillars 309 provide elastic support, allowing the inner bushing 301 to float freely within a certain range. This can effectively compensate for the vibration and displacement of the nozzle assembly 2 during operation and enhance the overall structural stability.

[0029] Working principle of this utility model: This utility model is a nozzle cooling mechanism for a floating bushing. First, the mounting base 1 is firmly fixed to the corresponding position of the equipment by bolts or welding. Then, the nozzle assembly 2 is installed on the mounting base 1, ensuring that the axis of the nozzle assembly 2 is consistent with the fluid spray direction of the equipment, and the sealing of the connection is ensured by a sealing gasket. In the cooling device 4, the coolant storage tank 401 stores coolant. The circulation pump 402 is started, pumping the coolant through the output pipe 403 into the cooling pipe 404, which is spirally fixed to the outer circumferential surface of the inner bushing 301. The coolant flows in the pipe, absorbing the heat generated by the nozzle assembly 2 and the floating bushing during operation, and then flows through the connecting pipe 4. 05 flows into the radiator 406 for heat dissipation and cooling, and finally flows back to the coolant storage tank 401 through the return pipe 407. This cycle maintains cooling. At the same time, in the floating bushing device 3, the lubricating layer on the inner wall of the inner bushing 301 reduces its friction with the outer surface of the nozzle assembly 2. The inner bushing 301 and the outer bushing 302 form a sealed annular chamber through the sealing annular groove 303, the first sealing ring 304 and the second sealing ring 305 to prevent coolant leakage and impurities from entering. Multiple sets of first fixing blocks 307, second fixing blocks 308 and spring columns 309 allow the inner bushing 301 to float freely within a certain range, compensating for the vibration and displacement of the nozzle assembly 2 during operation and ensuring stable operation of the equipment. At this point, the entire process ends.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
