Abstract
Description
Technical Field
[0001] This utility model relates to the field of sunscreen production technology, specifically to a formulation device for sunscreen production. Background Technology
[0002] Sunscreen is a cosmetic product that contains sunscreen agents that can block or absorb ultraviolet rays to prevent the skin from getting tanned or sunburned. Sunscreen works by using inorganic and organic active ingredients. Based on the principle of sun protection, sunscreen can be divided into physical sunscreen and chemical sunscreen.
[0003] The preparation of sunscreen requires mixing multiple raw materials. However, most existing mixing devices simply use a single vertical stirring roller to stir the raw materials. As a result, some raw materials are stuck to the inner wall of the mixing tank due to centrifugal force and cannot participate in the mixing. This leads to uneven mixing of the raw materials, reduces the mixing effect of the device, and affects the quality of the sunscreen. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a formulation device for sunscreen production, so as to solve the technical problems in the background art mentioned above.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a formulation device for sunscreen production, comprising a base, a mounting plate on the top of the base, a groove on one side of the mounting plate, a formulation container mounted inside the groove via a gear cylinder, a transmission gear fixed in the middle of one side of the mounting plate via a connecting shaft, a motor mounted on the other side of the mounting plate, a drive shaft extending into the formulation container connected to the output end of the motor, a drive gear and a drive bevel gear fixed to the outer surface of the drive shaft, a stirring shaft mounted at the lower and upper interior of the formulation container, a driven bevel gear fixed to one end of the stirring shaft, a stirring blade and a fixing rod on the outer surface of the stirring shaft, and a scraper fixed to one end of the fixing rod.
[0006] Furthermore, a mounting box is fixed inside the middle of the preparation tank via a connecting rod, and both the driving bevel gear and the driven bevel gear are located inside the mounting box.
[0007] By adopting the above technical solution, the material can be prevented from getting stuck between the active and driven bevel teeth under the protection of the mounting box.
[0008] Furthermore, the scraper blade is in contact with the inner wall of the preparation tank, and the scraper blade is made of rubber material.
[0009] By adopting the above technical solution, the scraper can scrape off the material adhering to the inner wall of the mixing tank and re-participate in the mixing, and the rubber material can prevent the scraper from damaging the tank wall.
[0010] Furthermore, the driving gear meshes with the transmission gear, and the transmission gear meshes with the gear cylinder.
[0011] By adopting the above technical solution, the rotation of the driving gear can drive the rotation of the transmission gear, and the rotation of the transmission gear can drive the rotation of the gear cylinder.
[0012] Furthermore, the preparation tank is rotatably engaged with the toothed cylinder and the sliding groove.
[0013] By adopting the above technical solution, the toothed cylinder can slide in the groove when it rotates, thereby causing the preparation tank to flip.
[0014] Furthermore, a protective railing is welded to the outer surface of the mounting plate, and the preparation tank is located inside the protective railing.
[0015] By adopting the above technical solution, the guardrail can play a role in isolation, thereby preventing workers from getting injured when they get close to the rotating mixing tank.
[0016] Furthermore, the top of the preparation tank is equipped with a feeding port, and the lower part of the outer surface of the preparation tank is provided with a discharge port.
[0017] By adopting the above technical solution, staff can add materials into the preparation tank through the feeding port, and after the preparation is completed, staff can open the discharge port to discharge the materials.
[0018] Furthermore, an observation window is provided in the middle of the outer surface of the preparation tank, and the observation window is made of tempered glass.
[0019] By adopting the above technical solution, staff can stop the machine at any time through the observation window to check the internal preparation status.
[0020] Furthermore, a control panel is provided on the outer surface of the mounting plate, and the motor is electrically connected to the control panel.
[0021] By adopting the above technical solution, staff can operate the motor through the control panel, controlling its start-up, shutdown, and speed.
[0022] Furthermore, the bottom of the base is provided with an anti-slip pad, which is made of rubber material.
[0023] By adopting the above technical solution, the device is placed more stably thanks to the anti-slip pad made of rubber material.
[0024] In summary, the present invention has the following main advantages:
[0025] 1. This utility model, by comprising a toothed cylinder, a transmission gear, a drive gear, and a chute, allows the mixing tank to rotate during preparation. The rotation of the motor causes the drive shaft to rotate, which in turn causes the drive gear to rotate. The drive gear, in turn, causes the toothed cylinder to rotate within the chute, thereby causing the mixing tank to tumble up and down. This method can prevent the sedimentation of some raw materials with a high specific gravity, allowing the sedimented raw materials to continuously participate in the mixing and ensuring the stirring effect.
[0026] 2. Based on the above-mentioned configuration, this utility model further includes a stirring shaft, a driving conical tooth, a driven conical tooth, a stirring blade, a fixing rod, and a scraper. When the motor drives the drive shaft to rotate, it also drives the driving conical tooth to rotate. The rotation of the driving conical tooth drives the driven conical tooth to rotate, thereby causing the stirring shaft to drive the stirring blade to rotate. The rotation of the stirring blade can rotate laterally, and in conjunction with the up-and-down tumbling of the above-mentioned preparation tank, it accelerates the mixing of various raw materials, thereby improving the mixing effect of the device on the raw materials. Furthermore, the rotation of the stirring shaft also drives the scraper to rotate through the fixing rod. The scraper can continuously scrape the inner wall of the preparation tank, causing the material adhering to the tank wall to be continuously scraped off and mixed, making the raw materials more evenly mixed and ensuring the quality of the sunscreen.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0034] The embodiments of this utility model will be described below based on its overall structure.
[0035] Example 1: A formulation apparatus for sunscreen production, such as... Figures 1-5 As shown, the system includes a base 1, with a mounting plate 2 on top. A groove 20 is formed on one side of the mounting plate 2, and a mixing tank 7 is mounted inside the groove 20 via a gear cylinder 6. A feeding port 8 is mounted on the top of the mixing tank 7, and a discharge port 23 is located below the outer surface of the mixing tank 7. Workers can add materials to the mixing tank 7 through the feeding port 8. After preparation, workers can open the discharge port 23 to discharge the materials. A transmission gear 12 is fixed to the middle of one side of the mounting plate 2 via a connecting shaft 22. A motor 4 is mounted on the other side of the mounting plate 2. The output end of the motor 4 is connected to a drive shaft 10 extending into the mixing tank 7. A drive gear 11 and a drive cone are fixed to the outer surface of the drive shaft 10. The mixing tank 7 has a connecting rod 21 that connects to a mounting box 13. Both the active conical tooth 19 and the driven conical tooth 18 are located inside the mounting box 13. Under the protection of the mounting box 13, materials can be prevented from getting stuck between the active conical tooth 19 and the driven conical tooth 18. The mixing tank 7 has a stirring shaft 14 installed at the bottom and top. One end of the stirring shaft 14 is fixed with the driven conical tooth 18. The outer surface of the stirring shaft 14 is provided with a stirring blade 15 and a fixing rod 16. One end of the fixing rod 16 is fixed with a scraper 17. The bottom of the base 1 is provided with an anti-slip pad 24, which is made of rubber material. The anti-slip pad 24 makes the device more stable.
[0036] See Figure 2 In the above embodiment, the scraper 17 is in contact with the inner wall of the preparation tank 7, and the scraper 17 is made of rubber material. The scraper 17 can scrape off the material adhering to the inner wall of the preparation tank 7 and re-participate in the stirring. The rubber material can prevent the scraper 17 from damaging the tank wall.
[0037] See Figure 2 , Figure 3 and Figure 5In the above embodiment, the drive gear 11 meshes with the transmission gear 12, and the transmission gear 12 meshes with the gear cylinder 6. The rotation of the drive gear 11 can drive the transmission gear 12 to rotate, and the rotation of the transmission gear 12 can drive the gear cylinder 6 to rotate. The preparation tank 7 is rotatably engaged with the slide groove 20 through the gear cylinder 6. When the gear cylinder 6 rotates, it can slide in the slide groove 20, thereby causing the preparation tank 7 to flip.
[0038] See Figure 1 In the above embodiment, an observation window 9 is provided in the middle of the outer surface of the preparation tank 7, and the observation window 9 is made of tempered glass. The staff can stop the machine at any time to check the preparation status through the observation window 9.
[0039] See Figures 1-2 In the above embodiment, a control panel 3 is provided above the outer surface of the mounting plate 2, and the motor 4 is electrically connected to the control panel 3. The operator can control the motor 4 through the control panel 3 to control the start, stop and speed of the motor 4.
[0040] Example 2: To prevent accidental injury to workers when the mixing tank rotates, Example 2 is an improvement on Example 1. (See attached document.) Figures 1-3 The outer surface of the mounting plate 2 is welded with a protective railing 5, and the preparation tank 7 is located inside the protective railing 5. The protective railing 5 can play an isolation role, thereby preventing workers from getting injured when they approach the rotating preparation tank 7.
[0041] The implementation principle of this utility model is as follows: First, the operator connects the power supply to the device, then pours the raw materials into the preparation tank 7, and then starts the motor 4. The rotation of the motor 4 causes the drive shaft 10 to rotate, which in turn causes the drive gear 11 to rotate. The drive gear 11 then causes the transmission gear 12 to rotate, which in turn drives the gear cylinder 6 to rotate within the slide groove 20. This causes the preparation tank 7 to tumble up and down. This method can prevent the sedimentation of some raw materials with a higher specific gravity. When the motor 4 drives the drive shaft 10 to rotate, it also drives the drive bevel gear 19 to rotate. The rotation drives the driven bevel gear 18 to rotate, which in turn causes the stirring shaft 14 to drive the stirring blade 15 to rotate. The rotation of the stirring blade 15 allows for lateral rotation, which, combined with the up-and-down tumbling of the preparation tank 7, accelerates the mixing of various raw materials, thereby improving the mixing effect of the device. Furthermore, the rotation of the stirring shaft 14 also drives the scraper 17 to rotate via the fixed rod 16. The scraper 17 continuously scrapes the inner wall of the preparation tank 7, causing the material adhering to the tank wall to be continuously scraped off and mixed, making the raw materials more evenly mixed. After the mixing is completed, the operator can open the discharge port 23 to discharge the material.
