Description

Technical Field

[0001] This utility model relates to the field of nozzle angle adjustment technology, specifically to an adjustable nozzle angle mechanism for meltblown equipment. Background Technology

[0002] In today's globalized industrial manufacturing sector, meltblown technology, as a key nonwoven fabric production process, plays a crucial role in numerous industries such as medical and health care, protective equipment, and filter materials. As the core carrier of this technology, the meltblown equipment, particularly its nozzle, directly determines the quality and performance of the meltblown products.

[0003] Adjusting the nozzle angle requires operators to use various tools, such as wrenches and pliers, to disassemble the nozzle's fixing components one by one. Then, the nozzle angle is adjusted by manually bending and rotating the components. Finally, the components need to be reinstalled and fixed. This process involves many steps and is very cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable nozzle angle mechanism for a meltblown equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable nozzle angle mechanism for a meltblown equipment, comprising:

[0006] Mounting plate;

[0007] A transmission assembly is placed inside a mounting plate. The transmission assembly includes a connecting frame fixedly connected to the mounting plate. A fourth gear, a fifth gear, and a sixth gear are slidably connected to the connecting frame. A second connecting rod is fixedly connected to the fifth gear. A second fixing frame is fixedly connected to the second connecting rod. A first connecting rod is fixedly connected to the sixth gear. A third fixing frame is fixedly connected to the first connecting rod. A first fixing frame is fixedly connected to the sixth gear. A first transmission rod is fixedly connected to each of the first, second, and third fixing frames. A first rotating shaft is rotatably connected to the first transmission rod. A second transmission rod is rotatably connected to the first rotating shaft. A second rotating shaft is rotatably connected to the second transmission rod. A mounting frame is rotatably connected to the second rotating shaft.

[0008] The motor is provided in three parts, and a second gear, a third gear and a first gear are respectively fixedly connected to the output end of the three motors. The motor is fixedly connected to the mounting plate.

[0009] Furthermore, the connecting frame has openings, and the third gear has three openings. The fourth gear, the fifth gear, and the sixth gear are slidably connected in the openings on the connecting frame.

[0010] The above technical solution is adopted: by opening holes on the connecting frame, the fourth, fifth and sixth gears are limited.

[0011] Furthermore, a fixing rod is fixedly connected to the inner wall of the connecting frame near the opening.

[0012] The above technical solution involves fixing a rod to the inner wall of the connecting frame near the opening, thus securing the entire connecting frame and preventing it from falling off.

[0013] Furthermore, a fixed chamber is fixedly connected to the mounting plate, and the third gear is slidably connected to the inner wall of the fixed chamber.

[0014] The above technical solution is adopted: by setting a third gear to slide on the inner wall of the fixed chamber, the gear is limited and protected.

[0015] Furthermore, a nozzle body is fixedly connected to the mounting frame.

[0016] The above technical solution involves fixing the nozzle body to the mounting frame, allowing the nozzle body to rotate as the mounting frame rotates.

[0017] Furthermore, the third fixed frame is slidably connected to the top of the second fixed frame.

[0018] The above technical solution is adopted: by setting a third fixed frame to slide on the top of the second fixed frame, the third fixed frame is offset from the second fixed frame, so as to ensure that it can drive different first transmission rods to move respectively.

[0019] Furthermore, both the mounting plate and the mounting frame are provided with threaded holes.

[0020] The above technical solution is adopted: threaded holes are provided on both the mounting plate and the mounting frame, which facilitates the use of bolts to fix the mounting plate inside the machine during use, and the threaded holes on the mounting frame are used to fix the nozzle body.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a motor serves as the power source, fixedly mounted on a mounting plate and connected to the bottom of the first, second, or third gear. When the nozzle angle needs adjustment, the motor on one side is activated, driving the connected gear (such as the second gear) to rotate. This gear meshes with the fifth gear, causing it to rotate. The fourth gear is fixedly connected to the third fixed frame via a first connecting rod, and its rotation drives the third fixed frame to rotate via the first connecting rod. The fifth gear, in turn, drives the second fixed frame to rotate via a second connecting rod fixed to it. The sixth gear directly drives the first fixed frame to rotate. Each of these three fixed frames has a first transmission rod fixed to it. The first transmission rod is connected to the second transmission rod via a first rotating shaft. When the first transmission rod moves with the fixed frame, under the limiting coordination of the other two stationary first transmission rods, it causes one side of the connected second transmission rod to move, ultimately causing the second transmission rod to rotate the mounting frame, thus adjusting the nozzle angle. The entire transmission process is tightly and orderly, with each component cooperating with the others, fully utilizing the driving force of the motor and the linkage efficiency of the gears, connecting rods, and transmission rods. This ensures that the nozzle angle can be flexibly changed according to requirements, solving the problem of cumbersome manual adjustment in existing technologies. Attached Figure Description

[0034] 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.

[0035] Example:

[0036] like Figures 1-5 As shown, this utility model provides a technical solution: an adjustable nozzle angle mechanism for a meltblown equipment, comprising:

[0037] Mounting plate 1;

[0038] Transmission assembly 2 is placed inside mounting plate 1. Transmission assembly 2 includes a connecting frame 24 fixedly connected inside mounting plate 1. A fourth gear 25, a fifth gear 26, and a sixth gear 27 are slidably connected to the connecting frame 24. A second connecting rod 212 is fixedly connected to the fifth gear 26. A second fixing frame 29 is fixedly connected to the second connecting rod 212. A first connecting rod 211 is fixedly connected to the sixth gear 27. A third fixing frame 210 is fixedly connected to the first connecting rod 211. A first fixing frame 28 is fixedly connected to the sixth gear 27. A first transmission rod 213 is fixedly connected to the first fixing frame 28, the second fixing frame 29, and the third fixing frame 210. A first rotating shaft 214 is rotatably connected to the first transmission rod 213. A second transmission rod 215 is rotatably connected to the first rotating shaft 214. A second rotating shaft 216 is rotatably connected to the second transmission rod 215. A mounting frame 217 is rotatably connected to the second rotating shaft 216.

[0039] Motor 4, three motors 4 are provided, and the output ends of the three motors 4 are respectively fixedly connected to the second gear 22, the third gear 23 and the first gear 21. The motors 4 are fixedly connected to the mounting plate 1.

[0040] In this invention, motor 4 serves as a power source, fixedly mounted on mounting plate 1, and connected to the bottom of first gear 21, second gear 22, or third gear 23. When it is necessary to adjust the nozzle angle, motor 4 on one side is activated, and motor 4 drives the connected gear (such as second gear 22) to rotate. This gear meshes with fifth gear 26, thereby driving it to rotate. The fourth gear 25 is fixedly connected to the third fixed frame 210 via the first connecting rod 211. When rotating, it drives the third fixed frame 210 to rotate via the first connecting rod 211. The fifth gear 26 drives the second fixed frame 29 to rotate via the second connecting rod 212 fixed to it. The sixth gear 27 directly drives the first fixed frame 28 to rotate. Each of these three fixed frames is fixed with a first transmission rod 213. The first transmission rod 213 is connected to the second transmission rod 215 via the first rotating shaft 214. When the first transmission rod 213 moves with the fixed frame, under the limiting coordination of the other two stationary first transmission rods 213, it drives the second transmission rod 215 connected to it to move to one side, ultimately causing the second transmission rod 215 to drive the mounting frame 217 to rotate, thereby adjusting the nozzle angle. The entire transmission process is tight and orderly, with each component cooperating with each other, giving full play to the driving effect of the motor 4 and the linkage efficiency of the gears, connecting rods, and transmission rods, ensuring that the nozzle angle can be flexibly changed according to the requirements, and solving the problem of the existing technology relying on manual adjustment and cumbersome steps in the background technology.

[0041] Furthermore, such as Figures 1 to 5 As shown, the connecting frame 24 has openings, the third gear 23 has three openings, and the fourth gear 25, the fifth gear 26 and the sixth gear 27 are slidably connected in the openings on the connecting frame 24.

[0042] By providing openings in the connecting frame 24, which act as limiting holes, the fourth gear 25, the fifth gear 26, and the sixth gear 27 are limited.

[0043] A fixing rod 5 is fixedly connected to the inner wall of the connecting frame 24 near the opening. By fixing the fixing rod 5 to the inner wall of the connecting frame 24 near the opening, the connecting frame 24 is fixed in place to prevent it from falling off.

[0044] A fixed chamber 11 is fixedly connected to the mounting plate 1, and a third gear 23 is slidably connected to the inner wall of the fixed chamber 11. By setting the third gear 23 to be slidably connected to the inner wall of the fixed chamber 11, the gear is limited and protected.

[0045] The nozzle body 3 is fixedly connected to the mounting frame 217. By fixing the nozzle body 3 to the mounting frame 217, the nozzle body 3 can also be rotated when the mounting frame 217 is rotated.

[0046] The third fixed frame 210 is slidably connected to the top of the second fixed frame 29. By setting the third fixed frame 210 to be slidably connected to the top of the second fixed frame 29, the third fixed frame 210 and the second fixed frame 29 are staggered, ensuring that they can drive different first transmission rods 213 to move respectively.

[0047] The above solution also has the problem of not specifying how to install the nozzle and the mounting plate 1. Both the mounting plate 1 and the mounting frame 217 have threaded holes. By setting both the mounting plate 1 and the mounting frame 217 to have threaded holes, it is easy to use bolts to fix the mounting plate 1 in the machine. The threaded holes on the mounting frame 217 are used to fix the nozzle body 3.

[0048] Working principle: such as Figures 1-5 As shown, when in use, first use the threaded holes on the mounting frame 217 to fix the nozzle body 3 with bolts, and use the threaded holes on the mounting plate 1 to fix the mounting plate 1 inside the machine.

[0049] When the angle of the mounting frame 217 needs to be adjusted, the motor 4 on one side is started, causing the motor 4 to drive one of the first gear 21, the second gear 22, or the third gear 23 to rotate. This gear will drive the fourth gear 25, the fifth gear 26, or the sixth gear 27 that meshes with it to rotate. The fourth gear 25 drives the third fixed frame 210 to rotate through the first connecting rod 211. The fifth gear 26 drives the second fixed frame 29 to rotate through the second connecting rod 212. The sixth gear 27 directly drives the first fixed frame 28 to rotate, causing the first transmission rod 213 on one side to shift. Under the limiting action of the other two stationary first transmission rods 213, the shifted first transmission rod 213 will drive the second transmission rod 215 to shift on one side, causing the second transmission rod 215 to cause the mounting frame 217 to flip.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
