Description

Technical Field

[0001] This utility model belongs to the field of cosmetic preparation technology, and specifically relates to a cosmetic preparation device. Background Technology

[0002] In the process of producing cosmetics, the raw materials need to be stirred and emulsified. In order to improve the emulsification effect and efficiency, the raw materials are also heated.

[0003] Existing cosmetic preparation equipment, while meeting the basic requirements of sufficient heating and stirring of raw materials for emulsification, and capable of scraping away raw materials adhering to the inner wall of the device through a scraping structure to prevent damage from continuous overheating and ensure uniform mixing and thorough discharge, typically relies on a continuously rotating scraping structure driven by a stirring mechanism. However, the device only needs continuous stirring of the raw materials, not continuous scraping of the inner wall. This results in ineffective wear and tear on the scraping structure, significantly shortening its lifespan and requiring frequent replacements, thus failing to fully meet user needs. Utility Model Content

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a cosmetic preparation device that not only meets the basic requirements for cosmetic preparation, but also ensures that the scraping structure only rubs against the inner wall of the device during the scraping process, thereby avoiding ineffective wear of the scraping structure and extending its service life.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a cosmetic preparation device, including a preparation tank, a top cover provided on the top of the preparation tank, an electric heating device provided inside the side wall of the preparation tank, a stirring shaft that is rotatably mounted through the top cover, stirring blades provided on the stirring shaft, a vertical cylinder that is slidably sleeved on the stirring shaft, a connecting slot provided on the inner side wall of the vertical cylinder, a connecting plate that can be inserted into the connecting slot provided on the stirring shaft, and a scraper plate provided on the vertical cylinder through a horizontal plate.

[0006] As a further improvement of this utility model, a telescopic push rod is vertically arranged on the top cover, the output shaft of the telescopic push rod passes through the top cover, a connecting cylinder is rotatably arranged on the vertical cylinder, and a connecting plate connected to the output shaft of the telescopic push rod is arranged at the top of the connecting cylinder.

[0007] As a further improvement of this utility model, a guide tube is also provided on the top cover, and a guide rod that is inserted into the guide tube is provided on the connecting plate.

[0008] As a further improvement of this utility model, the side end of the scraper is also provided with a support groove that can engage with the side end of the stirring blade.

[0009] As a further improvement of this utility model, a drive motor is provided on the top cover, and a gear transmission assembly is provided between the output shaft of the drive motor and the stirring shaft. The drive motor drives the gear transmission assembly to drive the stirring shaft to rotate, and at the same time, the telescopic push rod can be linked to achieve automatic lifting and lowering of the scraping action. The entire system can realize coordinated automated control of stirring and scraping, reduce manual intervention, and improve production efficiency.

[0010] As a further improvement of this utility model, the horizontal plate is provided with a mounting slot, the scraper plate is provided with a mounting plate that engages with the mounting slot, the mounting slot is provided with a mounting bolt that is screwed and fixed to the mounting plate, and the mounting plate is provided with a threaded mounting hole that connects to the mounting bolt.

[0011] As a further improvement of this utility model, the top cover is snapped into the preparation tank, and the top cover is provided with fixing bolts for screwing the preparation tank in place, and the preparation tank is provided with threaded fixing holes for screwing into the fixing bolts.

[0012] As a further improvement of this utility model, a feed cylinder is provided on the top cover, and support legs and a discharge pipe are provided at the bottom of the preparation tank. A control valve is provided on the discharge pipe. A temperature sensor is also embedded in the inner wall of the preparation tank, and a temperature controller electrically connected to the electric heating device and the temperature sensor is provided on the outer wall of the preparation tank. The equipment is equipped with a built-in electric heating device and a temperature sensor, combined with an external temperature controller to achieve precise control of the internal temperature of the preparation tank, meeting the requirements of temperature-sensitive processes in cosmetic preparation and improving product quality consistency.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the scraper is mounted on the stirring shaft via a sliding vertical cylinder. Only when cleaning the inner wall of the tank is required is the vertical cylinder driven downwards by a telescopic push rod. Through the insertion and engagement of the connecting slot and connecting plate, the vertical cylinder is connected to the stirring shaft, allowing the scraper to rotate and scrape the material from the inner wall of the preparation tank. During non-scraping phases, the vertical cylinder is driven upwards by the telescopic push rod, separating from the connecting plate via the connecting slot and disengaging the vertical cylinder from the stirring shaft. This avoids continuous friction during the stirring process, significantly reducing ineffective wear and effectively extending the service life of the scraper structure.

[0014] Secondly, the cooperative structure of the guide cylinder and guide rod ensures that the connecting plate remains stable during lifting and lowering, preventing deviation and improving the stability and positioning accuracy of the scraping action, thus guaranteeing a uniform and reliable scraping effect. Because the vertical cylinder is rotatably equipped with a connecting cylinder, which is connected to the output shaft of the telescopic push rod via a connecting plate, and because the connecting plate is also subject to the insertion and engagement of the guide cylinder and guide rod, it prevents the telescopic push rod from having a tendency to rotate under the drive of the stirring shaft, and avoids damage to the telescopic push rod due to torsional forces. Thirdly, the scraper is equipped with a support slot, which can engage with the mixing blade during scraping to form an auxiliary support, preventing deformation or loosening due to excessive force during scraping, thus improving the overall stability and safety of operation.

[0015] Fourth, the scraper blades can be quickly snapped together through the mounting slots and mounting plates on the horizontal plate and fixed with mounting bolts. They are easy to disassemble and assemble, and are convenient for daily cleaning, maintenance or replacement of scraper blades made of different materials to meet the processing needs of different materials.

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2 As shown in Figures 3 and 5, a cosmetic preparation apparatus includes a preparation tank 101. A top cover 102 is provided on the top of the preparation tank 101. An electric heating device is provided inside the side wall of the preparation tank 101. A stirring shaft 103 is rotatably mounted through the top cover 102. The top cover 102 is rotatably connected to the stirring shaft 103 through a first bearing 110. A stirring blade 104 is provided on the stirring shaft 103. A vertical cylinder 105 is slidably mounted on the stirring shaft 103. A connecting slot 106 is provided on the inner side wall of the vertical cylinder 105. A connecting plate 107 that can be inserted into the connecting slot 106 is provided on the stirring shaft 103. A scraper 109 is provided on the vertical cylinder 105 through a horizontal plate 108.

[0021] like Figure 1 , 2 As shown, a telescopic push rod 201 is vertically arranged on the top cover 102. The output shaft of the telescopic push rod 201 passes through the top cover 102. A connecting cylinder 202 is rotatably arranged on the vertical cylinder 105. The connecting cylinder 202 is rotatably connected to the vertical cylinder 105 through a second bearing 203. A connecting plate 204 connected to the output shaft of the telescopic push rod 201 is arranged on the top of the connecting cylinder 202.

[0022] like Figure 1 , 2 As shown, a guide tube 205 is also provided on the top cover 102, and a guide rod 206 that is inserted into the guide tube 205 is provided on the connecting plate 204.

[0023] like Figure 2 , 4 As shown, the side end of the scraper 109 is also provided with a support groove 207 that can engage with the side end of the stirring blade 104.

[0024] like Figure 1As shown, a drive motor 208 is mounted on the top cover 102, and a gear transmission assembly 209 is provided between the output shaft of the drive motor 208 and the stirring shaft 103. The drive motor 208 is a servo geared motor. The drive motor 208 drives the gear transmission assembly 209 to rotate the stirring shaft 103, and at the same time, it can control the telescopic push rod 201 to realize the automatic lifting and lowering of the scraping action. The entire system can realize the coordinated automated control of stirring and scraping, reduce manual intervention, and improve production efficiency.

[0025] Workers can feed cosmetic raw materials into the tank through the feed cylinder 308, and then start the drive motor 208 (servo geared motor). The gear transmission assembly 209 drives the stirring shaft 103 to rotate, and the stirring blades 104 on the stirring shaft 103 begin to uniformly stir the materials inside the tank. Simultaneously, the electric heating device is activated, and a temperature sensor monitors the temperature inside the tank in real time, feeding the signal back to an external temperature controller to achieve closed-loop control of the heating process, ensuring stable reaction of the materials within the set temperature range. At this time, because the connecting slot 106 is separated from the connecting plate 107, and the vertical cylinder 105 is not rotatably connected to the stirring shaft 103, the stirring shaft 103 avoids driving the vertical cylinder 105, horizontal plate 108, and scraper 109 to rotate, thus preventing ineffective rotation and wear of the scraper 109.

[0026] When it is necessary to scrape off residual material from the inner wall of the tank (e.g., during mixing or before discharge), the drive motor 208 is first stopped, the mixing shaft 103 is stopped from rotating, and the connecting plate 107 is aligned with the connecting slot 106. Then, the telescopic push rod 201 can be driven to extend downward. The output shaft of the telescopic push rod 201 drives the connecting plate 204 to move downward, thereby pushing the vertical cylinder 105 to slide downward along the mixing shaft 103. As the vertical cylinder 105 moves downward, the connecting slot 106 on its inner wall gradually engages with the connecting plate 107 on the mixing shaft 103, realizing power transmission—at this time, the vertical cylinder 105 can rotate synchronously with the mixing shaft 103. The vertical cylinder 105 drives the scraper 109 to rotate together through the horizontal plate 108. At the same time, the guide rod 206 slides inside the guide cylinder 205, playing a guiding and anti-deviation role, ensuring that the vertical cylinder 105 descends smoothly and preventing the torque caused by rotation from being transmitted to the telescopic push rod 201.

[0027] After the scraper blade 109 descends to its designated position, the support groove 207 on its side engages with the side of the mixing blade 104, forming an auxiliary support structure. This effectively resists the reaction force during scraping, preventing the scraper blade 109 from deforming or loosening, and improving operational safety and scraping efficiency. Driven by the continuous rotation of the mixing shaft 103, the scraper blade 109 rotates close to the inner wall of the tank, scraping the material adhering to the wall back into the tank, achieving efficient self-cleaning, improving material utilization and mixing uniformity, and enhancing the thoroughness of discharge.

[0028] After scraping is completed, the drive motor 208 is first stopped, and the stirring shaft 103 stops rotating. Then, the output shaft of the drive telescopic push rod 201 shortens upward by a certain length and retracts upward, causing the vertical cylinder 105 to move upward along the stirring shaft 103. When the connecting slot 106 is completely disengaged from the connecting plate 107, the transmission between the vertical cylinder 105 and the stirring shaft 103 is disconnected, the scraper plate 109 disengages from the tank wall, and the scraping action stops. At this time, the scraper plate 109 is in a non-working position and no longer contacts the tank wall, avoiding ineffective wear during subsequent stirring.

[0029] According to another embodiment of the present invention, such as Figure 2 , 4 As shown, the horizontal plate 108 is provided with a mounting slot 301, and the scraper plate 109 is provided with a mounting plate 302 that engages with the mounting slot 301. The mounting slot 301 is provided with a mounting bolt 303 that is screwed and fixed to the mounting plate 302. The mounting plate 302 is provided with a threaded mounting hole that connects to the mounting bolt 303. By simply engaging the mounting plate 302 with the mounting slot 301 and then passing the mounting bolt 303 through the side wall of the mounting slot 301 and screwing it into the threaded mounting hole, the scraper plate 109 and the horizontal plate 108 can be flexibly fixed.

[0030] According to another embodiment of the present invention, such as Figure 1 As shown, the top cover 102 is snapped into the preparation tank 101. The top cover 102 is provided with a fixing bolt 304 for screwing the preparation tank 101 in place, and the preparation tank 101 is provided with a threaded fixing hole for screwing into the fixing bolt 304. By simply snapping the top cover 102 into the preparation tank 101 and then screwing the fixing bolt 304 through the side wall of the top cover 102 and into the threaded mounting hole, the top cover 102 and the preparation tank 101 can be flexibly fixed.

[0031] like Figure 1 As shown, a feed cylinder 308 is installed on the top cover 102, and a support leg 305 and a discharge pipe 306 are installed at the bottom of the preparation tank 101. A control valve 307 is installed on the discharge pipe 306. A temperature sensor is also embedded in the inner wall of the preparation tank 101, and a temperature controller electrically connected to the electric heating device and the temperature sensor is installed on the outer wall of the preparation tank 101. The equipment is equipped with a built-in electric heating device and a temperature sensor, combined with an external temperature controller to achieve precise control of the internal temperature of the preparation tank 101, meeting the requirements of temperature-sensitive processes in cosmetic preparation and improving product quality consistency.

[0032] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
