Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically to a speed reducer used for mixing cosmetics. Background Technology

[0002] Cosmetic mixing is a core step in the production process. It achieves multiple functions through physical and mechanical action and directly affects the uniformity, stability, and user experience of the product. The reducer in cosmetic mixing equipment is the core transmission component for achieving efficient and stable mixing. Its structural design must take into account requirements such as torque output, speed control, sealing, and corrosion resistance.

[0003] Typically, the speed reducers used for mixing cosmetics require two separate speed reducers to control the forward and reverse rotation of the main and auxiliary blades, resulting in complex equipment, high energy consumption, and difficult maintenance. In terms of sealing, they are usually sealed with sealing rings, which have a simple structure but unsatisfactory sealing effect. Utility Model Content

[0004] This invention provides a speed reducer for mixing cosmetics to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An embodiment of this utility model provides a speed reducer for mixing cosmetics, comprising:

[0007] A motor and a speed reducer, wherein the speed reducer is fixedly connected to the output end of the motor;

[0008] A bevel gear stirring device is provided, located at the output end of a reducer. The device includes a first bevel gear, a second bevel gear, a third bevel gear, a main shaft, a counter-shaft, four dry-well seals, a sealing cylinder, two mechanical seal assemblies, and a housing. The first bevel gear is fixedly connected to the output end of the reducer. The second and third bevel gears are symmetrically meshed on both sides of the first bevel gear. The sealing cylinder is connected to the inner wall of the second bevel gear via a flange. The counter-shaft is rotatably connected to the main shaft. Four dry-well seals are provided, divided into two groups: one group is located on the arc surface of the counter-shaft, and the other group is located on the main shaft. The mechanical seal assemblies are fixedly connected to the dry-well seals. Two mechanical seal assemblies are provided on each opposite side of the housing, and each mechanical seal assembly is fixedly connected to the sealing cylinder. The other end of the main shaft is fixedly connected to the center of the mechanical seal assembly.

[0009] Through the above technical solution, by setting up a bevel gear stirring device and using a bevel gear structure, it can achieve forward and reverse rotation with a single motor, making the cosmetic raw materials more uniform and the medium deposition more stable.

[0010] Furthermore, the bevel gear stirring device also includes a pump, which is fixedly connected to the housing, and a condenser pipe is fixedly connected to the output end of the pump.

[0011] The above technical solution allows the lubricating oil inside the bevel gear agitator to fully contact the outside by setting up a condenser pipe, thus achieving heat dissipation.

[0012] Furthermore, a filter is detachably installed at the output end of the condenser tube, and two filter screens are fixedly connected to the inner wall of the filter, as well as a sponge block is fixedly connected to the inner wall of the filter.

[0013] The above technical solution allows for the filtration of lubricating oil by setting up a filter.

[0014] Furthermore, aluminum fins are fixedly connected to the surface of the condenser tube, and a fan is slidably connected to the surface of the aluminum fins.

[0015] The above technical solution, by setting aluminum fins and a fan, can further achieve heat dissipation of the lubricating oil in the condenser tube.

[0016] Furthermore, the surface of the aluminum fin is provided with a slide rail, the surface of the fan is fixedly connected with a slider, the surface of the aluminum fin is provided with a plurality of fixing holes, and the inner wall of the slider is slidably connected with a fixing pin.

[0017] The above technical solution can be used to adjust the position of the fan.

[0018] Furthermore, a pull block is fixedly connected to one end of the fixing pin, a chamfer is provided at the other end of the fixing pin, a spring is fitted on the arc surface of the fixing pin, one end of the spring is fixedly connected to the pull block, and the other end of the spring is fixedly connected to the slider.

[0019] The above technical solution allows the fan to be fixed onto the aluminum fins.

[0020] The above-described solution of this utility model has at least the following beneficial effects:

[0021] This invention features a bevel gear stirring device. The bevel gear structure allows for forward and reverse rotation with a single motor, resulting in more uniform mixing of cosmetic raw materials and more stable media deposition. The main shaft is made of stainless steel, and the sealing uses a combination of dry gas seal and mechanical seal to minimize leakage of internal lubricating oil and protect the cosmetic raw materials in the mixing tank from contamination. Simultaneously, the lubricating oil flows through the condenser tube via a pump, and during this flow, a fan further reduces the temperature of the lubricating oil in the condenser tube, thus stabilizing the pressure changes on the outer shell caused by the high temperature of the lubricating oil.

[0036] like Figures 1 to 6 As shown, an embodiment of this utility model provides a speed reducer for stirring cosmetics, including: a motor 1 and a speed reducer 2, wherein the speed reducer 2 is fixedly connected to the output end of the motor 1;

[0037] A bevel gear stirring device 3 is located at the output end of the reducer 2. The bevel gear stirring device 3 includes a first bevel gear 301, a second bevel gear 302, a third bevel gear 305, a main shaft 303, a secondary shaft 308, four dry well seals 304, a sealing cylinder 306, two mechanical seal assemblies 307, and a housing 310. The first bevel gear 301 is fixedly connected to the output end of the reducer 2. The second bevel gear 302 and the third bevel gear 305 are symmetrically meshed on both sides of the first bevel gear 301. The sealing cylinder 306 is connected to the inner wall of the second bevel gear 302 via a flange. The secondary shaft 308 is rotatably connected to the main shaft 303. Four dry well seals 304 are provided, divided into two groups, one group being... The arc surface of the secondary shaft 308 is provided, and another set is set on the main shaft 303. The mechanical seal assembly 307 is fixedly connected to the dry well seal 304. Two mechanical seal assemblies 307 are provided on opposite sides of the outer shell 310. The mechanical seal assembly 307 is fixedly connected to the sealing cylinder 306. The other end of the main shaft 303 is fixedly connected to the center position of the mechanical seal assembly 307. By setting the bevel gear stirring device 3, the bevel gear structure allows it to achieve forward and reverse rotation with a single motor 1, making the cosmetic raw materials more uniform and the medium deposition more stable. The main shaft 303 is made of stainless steel, and the seal adopts a combination structure of dry gas seal and mechanical seal to minimize the leakage of internal lubricating oil and protect the cosmetic raw materials in the stirring tank from contamination.

[0038] It should be noted that the interior of the housing 310 is filled with lubricating oil, thereby reducing the friction between the three bevel gears and improving transmission efficiency. Meanwhile, the dry well seal 304 and the mechanical seal assembly 307 are already mature technologies on the market, so they will not be elaborated on in this article. The dry well seal 304 can improve the airtightness between the main shaft 303, the secondary shaft 308 and the mechanical seal assembly 307. The mechanical seal assembly 307 can prevent the lubricating oil inside the housing 310 from leaking during the rotation of the main shaft 303 and the secondary shaft 308 inside the housing 310.

[0039] When the reducer 2 is running, it drives the first bevel gear 301 to rotate, which in turn drives the second bevel gear 302 and the third bevel gear 305 to rotate synchronously. The rotation directions of the first bevel gear 301 and the second bevel gear 302 are opposite. During this process, the second bevel gear 302 drives the main shaft 303 to rotate, and the third bevel gear 305 drives the secondary shaft 308 to rotate. The main shaft 303 and the secondary shaft 308 move in opposite directions during rotation. At the same time, according to the needs of the scene, the staff can install blades or other components on the shaft surfaces of the main shaft 303 and the secondary shaft 308. The corresponding mounting holes are reserved on the main shaft 303 and the secondary shaft 308 (not shown in the figure). By installing blades on the main shaft 303 and the secondary shaft 308 respectively, the cosmetic raw materials can be stirred in both directions, so that the cosmetic raw materials are stirred more evenly and the medium deposition is more stable.

[0040] like Figures 3 to 5 As shown, the bevel gear stirring device 3 also includes a pump 309, which is fixedly connected to the outer casing 310. A condenser tube 322 is fixedly connected to the output end of the pump 309. By setting the condenser tube 322, the lubricating oil inside the bevel gear stirring device 3 can be fully exposed to the outside to achieve heat dissipation. A filter 319 is detachably installed at the output end of the condenser tube 322. Two filter screens 320 are fixedly connected to the inner wall of the filter 319, and a sponge block 321 is fixedly connected to the inner wall of the filter 319. By setting the filter 319, the lubricating oil can be filtered. Aluminum fins 311 are fixedly connected to the surface of the condenser tube 322, and a fan 312 is slidably connected to the surface of the aluminum fins 311. By setting the aluminum fins 311... The fan 312 can further dissipate heat from the lubricating oil in the condenser 322. The surface of the aluminum fin 311 is provided with a slide rail 313, and the surface of the fan 312 is fixedly connected with a slider 314. The surface of the aluminum fin 311 is provided with several fixing holes 315. The inner wall of the slider 314 is slidably connected with a fixing pin 318, which can realize the adjustment of the position of the fan 312. One end of the fixing pin 318 is fixedly connected with a pull block 316, and the other end of the fixing pin 318 is chamfered. The arc surface of the fixing pin 318 is fitted with a spring 317. One end of the spring 317 is fixedly connected to the pull block 316, and the other end of the spring 317 is fixedly connected to the slider 314, which can fix the fan 312 on the aluminum fin 311.

[0041] In this embodiment of the invention, when stirring is performed, the motor 1 drives the reducer 2, which in turn drives the first bevel gear 301 to rotate. The second bevel gear 302 and the third bevel gear 305 mesh with the first bevel gear 301 at a 120° angle. When the motor 11 rotates in one direction, the second bevel gear 302 and the third bevel gear 305 are alternately subjected to force to generate positive and negative torques. The main shaft 303 drives the stirring head to rotate and stir. During the stirring process, the dry well seal 304 and the mechanical seal assembly 307 ensure the sealing of the bevel gear stirring device 3, so that the bevel gear stirring device 3 never leaks lubricating oil and protects the cosmetic raw materials in the stirring tank from contamination.

[0042] Furthermore, the dry well seal 304 improves the airtightness between the housing 310 and the mechanical seal assembly 307.

[0043] This device also features a filtration and heat dissipation function. The lubricating oil inside the outer casing 310 is pumped into the condenser tube 322 by the pump 309. The condenser tube 322 cools the internal lubricating oil by contacting air. Simultaneously, the fan 312 and aluminum fins 311 also dissipate heat from the lubricating oil inside the condenser tube 322. When the lubricating oil returns to the device from the condenser tube 322, it passes through the filter 319. The filter screen 320 and sponge block 321 in the filter 319 filter the lubricating oil inside the bevel gear stirring device 3. The filter screen's pore size allows the lubricating oil to pass through smoothly. The filter screen and sponge block effectively cool the lubricating oil inside the outer casing. The lubricating oil is filtered to prevent metal debris from forming on the bevel gear during long-term operation, thus extending its service life to some extent. This also ensures the purity of the lubricating oil, guaranteeing its lubricating performance. Operators can pull the lever 316 to remove the fixing pin 318 from the fixing hole 315. At this time, the spring 317 is stretched, and the slider 314 slides on the slide rail 313 to find the appropriate fixing hole 315. Releasing the lever 316 allows the fixing pin 318 to be inserted into the fixing hole 315, thereby adjusting the position of the fan 312.

[0044] The device provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
