Description

Technical Field

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

[0002] In today's booming beauty and cosmetics industry, makeup brushes are indispensable tools for makeup artists and enthusiasts, and their quality directly affects the makeup effect. A makeup brush consists of two parts: bristles and a handle. The quality of the bristles depends not only on the material but also on the fine finishing of the bristle tips.

[0003] In traditional makeup brush production, bristle polishing largely relies on manual labor. Workers hold the brushes and use simple polishing tools such as sandpaper and grinding wheels to individually polish the bristle tips. This method has many drawbacks: First, manual polishing is extremely inefficient; a skilled worker can only process a limited number of brushes per day, making it difficult to meet the output demands of large-scale industrial production. As market demand for makeup brushes increases year by year, manufacturers face enormous supply pressure, and inefficient manual polishing has become a bottleneck for increasing production capacity.

[0004] Secondly, the quality of manual polishing varies. Different workers have different techniques, strengths, and experiences, making it difficult to guarantee a uniform standard for the evenness and flatness of the brush bristle tips. This reduces the user experience and consequently affects the brand's reputation.

[0005] Existing grinding devices often create blind spots during grinding, requiring manual secondary grinding, which significantly slows down production. Utility Model Content

[0006] The purpose of this invention is to provide a makeup brush polishing device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A makeup brush polishing device includes a support leg, a polishing platform fixedly mounted on the top of the support leg, a bracket fixedly mounted on the top of the polishing platform, a cylinder fixedly mounted on the inner wall of the bracket, a crossbar slidably mounted on the inner side of the bracket, the output end of the cylinder fixedly mounted to the crossbar, a pushing mechanism on the top of the polishing platform capable of pushing and pulling, a clamping mechanism on the top of the polishing platform capable of clamping the makeup brush, a moving mechanism on the top of the polishing platform capable of lateral movement of the makeup brush, a fixing mechanism on the top of the polishing platform capable of reinforcing the clamped makeup brush, a polishing mechanism at the bottom of the crossbar capable of polishing the makeup brush, and a driving mechanism at the bottom of the crossbar capable of rotating the polishing mechanism by pushing.

[0009] A further improvement of this utility model is that the pushing mechanism includes a fixed plate, a first electric push rod, a piston rod, and a fixed frame. Two sets of fixed plates are provided, and the two sets of fixed plates are fixedly installed on both sides of the top of the grinding platform. The top of the fixed plate is fixedly installed with the first electric push rod. The fixed frame is fixedly installed on the top of the grinding platform. The fixed frame is located on the side of the fixed plate away from the support. The piston rod is fixedly installed at the output end of the first electric push rod. The piston rod is slidably installed with the fixed frame.

[0010] By adopting the above technical solution, the cooperation between the fixing plate and the fixing frame can provide good working space for the first electric push rod and the piston rod. The first electric push rod can push and pull the piston rod. When the piston rod is pulled, the clamping rod will clamp the makeup brush, and vice versa, thus improving the efficiency of the clamping mechanism.

[0011] A further improvement of the present invention is that the clamping mechanism includes a fixed rod, a clamping rod, and a first rotating frame. The fixed rod is fixedly installed on both sides of the fixed frame, and the first rotating frame is fixedly installed on both sides of the piston rod away from the first electric push rod. The clamping rod is rotatably installed on both sides of the first rotating frame, and the end of the fixed rod away from the fixed frame is rotatably installed with the clamping rod.

[0012] Using the above technical solution, the connection between the fixed rod and the fixed frame enables the clamping rod to rotate around the fixed rod as the center point when rotating. The cooperation between the first rotating frame and the clamping rod enables clamping and loosening through the pushing and pulling of the piston rod.

[0013] A further improvement of this utility model's technical solution is that the moving mechanism includes a limiting plate, a supporting plate, a second electric push rod, and a suction cup. The limiting plate is fixedly installed on the top of the grinding platform. The limiting plate is located at the end of the piston rod away from the first electric push rod. The limiting plate and the piston rod are movably installed together. The supporting plate is fixedly installed on the side of the limiting plate away from the piston rod. The second electric push rod is fixedly installed on the top of the supporting plate. The output end of the second electric push rod is fixedly installed with the suction cup.

[0014] Using the above technical solution, the combination of the limiting plate and the support plate can limit the piston rod so that it does not move excessively and keeps it within a safe range. The combination of the second electric push rod and the suction cup can pull the makeup brush during polishing so that the part covered by the clamped half ring can be exposed and polished, avoiding omissions when polishing the makeup brush.

[0015] A further improvement of the present invention is that the fixing mechanism includes a clamping half-ring, a second rotating frame, balls, and an anti-slip pad. The second rotating frame is fixedly installed on the inner wall of the clamping rod away from the first rotating frame. The clamping half-ring is rotatably installed on both sides of the second rotating frame. Several sets of balls are provided, and the several sets of balls are rotatably installed on the inner wall of the clamping half-ring in a ring. The anti-slip pad is fixedly installed on the inner wall of the clamping half-ring.

[0016] Using the above technical solution, the combination of the clamping half-ring and the second rotating frame can reinforce the makeup brush. At the same time, the clamping half-ring can rotate at a certain angle according to the curvature of both ends of the makeup brush, which can increase the contact area with the makeup brush and improve the stability during polishing. The ball bearings can make the makeup brush move more smoothly and reduce friction. The anti-slip pads can reinforce the makeup brush to a certain extent and make it less easy to rotate.

[0017] A further improvement of the present invention is that the driving mechanism includes an L-shaped fixed frame, a third electric push rod, a fixed slider, and a sliding frame. The L-shaped fixed frame is fixedly installed on one side of the bottom of the crossbar. The inner side of the L-shaped fixed frame is fixedly installed with the third electric push rod. The output end of the third electric push rod is fixedly installed with the fixed slider. The inner wall of the fixed slider is slidably installed with the sliding frame. The sliding frame is slidably installed with the crossbar.

[0018] Using the above technical solution, the L-shaped fixed frame and the third electric push rod work together to push the fixed slider to move. The fixed slider can make the sliding frame move laterally by pushing the third electric push rod. When the sliding frame moves laterally, it will push the sliding column to rotate. When the sliding column rotates, it will slowly descend, and at that time the sliding frame will also be pulled down by the sliding column.

[0019] A further improvement of this utility model is that the grinding mechanism includes a fixed column, a U-shaped frame, a sliding column, a motor, and a grinding ball. The fixed column is fixedly installed at the bottom of the crossbar, and the end of the fixed column away from the crossbar is fixedly installed with the U-shaped frame. A trapezoidal groove is provided on the inner wall of the U-shaped frame. The sliding column is slidably installed on the inner wall of the U-shaped frame. The motor is fixedly installed on the inner wall of the sliding column. A sliding plate located on the inner wall of the sliding frame is provided on one side of the surface of the sliding column. The output end of the motor is fixedly installed with the grinding ball.

[0020] Using the above technical solution, the combination of the fixed column and the U-shaped frame enables the sliding column to be used and slid stably. The sliding column can slide freely on the inner wall of the U-shaped frame, thereby changing the direction of the polishing ball. The combination of the motor and the polishing ball enables the makeup brush to be polished quickly.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides a makeup brush polishing device. Through the arrangement of a pushing mechanism, a clamping mechanism, a moving mechanism, a fixing mechanism, a driving mechanism, and a polishing mechanism, the pushing and clamping mechanisms work together to clamp and release the makeup brush. The moving mechanism allows the makeup brush to move laterally, exposing hard-to-reach areas for comprehensive polishing. The fixing mechanism reinforces the makeup brush and increases the contact area with the brush, making it more stable. The driving mechanism pushes the polishing mechanism to rotate at a certain angle, improving polishing efficiency. The polishing mechanism can quickly and efficiently polish the makeup brush, effectively reducing polishing dead corners. By using the pushing, clamping, moving, fixing, driving, and polishing mechanisms in combination, this invention solves the problem of dead corners appearing during polishing in the prior art, requiring secondary manual polishing and significantly delaying production.

[0023] 2. This utility model provides a cosmetic brush polishing device. By setting up a fixed plate, a first electric push rod, a piston rod, and a fixed frame, the cooperation between the fixed plate and the fixed frame can provide good working space for the first electric push rod and the piston rod. The first electric push rod can push and pull the piston rod. When the piston rod is pulled, the clamping rod will clamp the cosmetic brush, and vice versa, thus improving the efficiency of the clamping mechanism.

[0024] 3. This utility model provides a cosmetic brush polishing device. By setting up a fixed rod, a clamping rod and a first rotating frame, the connection between the fixed rod and the fixed frame enables the clamping rod to rotate around the fixed rod as the center point when rotating. The cooperation between the first rotating frame and the clamping rod enables clamping and loosening through the pushing and pulling of the piston rod. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to embodiments:

[0032] Example 1

[0033] like Figure 1-5As shown, this utility model provides a cosmetic brush polishing device, including a support leg 1, a polishing platform 2 fixedly mounted on the top of the support leg 1, a bracket 3 fixedly mounted on the top of the polishing platform 2, a cylinder 4 fixedly mounted on the inner wall of the bracket 3, a crossbar 5 slidably mounted on the inner side of the bracket 3, and the output end of the cylinder 4 fixedly mounted to the crossbar 5.

The first rotating frame 73 is fixedly installed on both sides of the piston rod 63 away from the first electric push rod 62. The clamping rod 72 is rotatably installed on both sides of the first rotating frame 73. The end of the fixed rod 71 away from the fixed frame 64 is rotatably installed with the clamping rod 72. A moving mechanism 8 is provided on the top of the polishing platform 2. The moving mechanism 8 enables the makeup brush to move laterally. The moving mechanism 8 includes a limiting plate 81, a support plate 82, a second electric push rod 83, and a suction cup 84. The limiting plate 81 is fixedly installed on the top of the grinding platform 2. The limiting plate 81 is located at the end of the piston rod 63 away from the first electric push rod 62. The limiting plate 81 and the piston rod 63 are movably installed. The support plate 82 is fixedly installed on the side of the limiting plate 81 away from the piston rod 63. The second electric push rod 83 is fixedly installed on the top of the support plate 82. The output end of the second electric push rod 83 is fixedly installed with the suction cup 84.

[0034] In this embodiment, the arrangement of the pushing mechanism 6, clamping mechanism 7, moving mechanism 8, fixing mechanism 9, driving mechanism 10, and polishing mechanism 11 allows the pushing mechanism 6 and clamping mechanism 7 to clamp and release the makeup brush. The moving mechanism 8 allows the makeup brush to move laterally, exposing hard-to-reach areas for thorough polishing. The fixing mechanism 9 reinforces the makeup brush and increases the contact area with it, making it more stable. The driving mechanism 10 drives the polishing mechanism 11 to rotate at a certain angle, improving polishing efficiency. The polishing mechanism 11 can quickly and efficiently polish the makeup brush and effectively reduce polishing dead areas. The cooperation between the fixing plate 61 and the fixing frame 64 provides good working space for the first electric push rod 62 and piston rod 63. The first electric push rod 62 can... The piston rod 63 is pushed and pulled. When the piston rod 63 is pulled, the clamping rod 72 clamps the makeup brush, and vice versa, which improves the efficiency of the clamping mechanism 7. The connection between the fixed rod 71 and the fixed frame 64 allows the clamping rod 72 to rotate around the fixed rod 71 as the center point. The cooperation between the first rotating frame 73 and the clamping rod 72 can achieve clamping and loosening by pushing and pulling the piston rod 63. The cooperation between the limiting plate 81 and the support plate 82 can limit the piston rod 63 so that it does not move excessively and always keeps it within a safe range. The cooperation between the second electric push rod 83 and the suction cup 84 can pull the makeup brush with the suction of the suction cup 84 during polishing so that the part covered by the clamping half ring 91 can be exposed and polished, avoiding omissions when polishing the makeup brush.

[0035] Example 2

[0036] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the fixing mechanism 9 includes a clamping half-ring 91, a second rotating frame 92, ball bearings 93, and an anti-slip pad 94. The second rotating frame 92 is fixedly installed on the inner wall of the clamping rod 72 away from the first rotating frame 73. The clamping half-ring 91 is rotatably installed on both sides of the second rotating frame 92. Several sets of ball bearings 93 are provided, and the several sets of ball bearings 93 are rotatably installed on the inner wall of the clamping half-ring 91 in a ring. The anti-slip pad 94 is fixedly installed on the inner wall of the clamping half-ring 91. The driving mechanism 10 includes an L-shaped fixing frame 101, a third electric push rod 102, a fixed slider 103, and a sliding frame 104. The L-shaped fixing frame 101 is fixedly installed on one side of the bottom of the crossbar 5. The inner side of the L-shaped fixing frame 101 is connected to the third electric push rod 102. The third electric push rod 102 is fixedly installed with the output end of the fixed slider 103. The inner wall of the fixed slider 103 is slidably installed with the sliding frame 104. The sliding frame 104 is slidably installed with the crossbar 5. The grinding mechanism 11 includes a fixed column 111, a U-shaped frame 112, a sliding column 113, a motor 114, and a grinding ball 115. The fixed column 111 is fixedly installed at the bottom of the crossbar 5. The end of the fixed column 111 away from the crossbar 5 is fixedly installed with the U-shaped frame 112. The inner wall of the U-shaped frame 112 is provided with a trapezoidal groove. The sliding column 113 is slidably installed on the inner wall of the U-shaped frame 112. The motor 114 is fixedly installed on the inner wall of the sliding column 113. A sliding plate located on the inner wall of the sliding frame 104 is provided on one side of the surface of the sliding column 113. The output end of the motor 114 is fixedly installed with the grinding ball 115.

[0037] In this embodiment, the clamping half-ring 91 and the second rotating frame 92 work together to reinforce the makeup brush. Simultaneously, the clamping half-ring 91 can rotate at a certain angle according to the curvature of both ends of the makeup brush, increasing the contact area with the brush and improving stability during polishing. The ball bearing 93 makes the makeup brush move more smoothly while reducing friction. The anti-slip pad 94 reinforces the makeup brush, preventing it from rotating easily. The L-shaped fixing frame 101 and the third electric push rod 102 work together to push the fixed slider 103 to move. The fixed slider 103 is moved by the third electric push rod 102. The push enables the sliding frame 104 to move laterally. When the sliding frame 104 moves laterally, it pushes the sliding column 113 to rotate. When the sliding column 113 rotates, it will slowly descend. At that time, the sliding frame 104 will also be pulled down by the sliding column 113. The cooperation between the fixed column 111 and the U-shaped frame 112 enables the sliding column 113 to be used and slid stably. The sliding column 113 can slide freely on the inner wall of the U-shaped frame 112, thereby changing the direction of the polishing ball 115. The cooperation between the motor 114 and the polishing ball 115 enables the makeup brush to be polished quickly.

[0038] The working principle of this makeup brush polishing device will be explained in detail below.

[0039] like Figure 1-5 As shown, when using this utility model, first place the polishing platform 2 in a flat position, then place the makeup brush on top of the polishing platform 2, and then activate the first electric push rod 62 to retract it. When the first electric push rod 62 retracts, it will cause the piston rod 63 to pull the first rotating frame 73 and the clamping rod 72. At the same time, when the piston rod 63 retracts, it will cause the clamping rod 72 to rotate around one end of the fixed rod 71. When the clamping rod 72 rotates, it will clamp the brush. When the clamping rod 72 clamps the brush, the clamping half ring 91 will reinforce the makeup brush. At the same time, the second rotating frame 92 is set up... The clamping half-ring 91 can rotate at a certain angle to better fit the makeup brush. When the makeup brush is clamped, the motor 114 is started to drive the polishing ball 115 to rotate. Then, the cylinder 4 is started to pull the crossbar 5 to descend. When the polishing ball 115 contacts the makeup brush, it polishes it. At the same time, the user can start the third electric push rod 102 to push the fixed slider 103 to move. When the fixed slider 103 moves, it pushes the sliding frame 104 to move. When the sliding frame 104 is pushed, it will cause the sliding column 113 to move within the U-shaped frame 1. The brush slides within the 12 slots. As the sliding column 113 slides, it tilts, and the sliding frame 104 slowly descends due to the tilt of the sliding column 113. The sliding column 113 tilts the polishing ball 115, allowing for more thorough polishing of the makeup brush. After polishing, the user can activate the second electric push rod 83 to move the suction cup 84. As the suction cup 84 moves, it grips one end of the makeup brush. Then, the support plate 82 retracts, allowing the makeup brush to move laterally. When the makeup brush reaches a certain angle and is clamped... When the part covered by the tight half ring 91 is exposed, the polishing ball 115 is then operated to polish. The two sets of second electric push rods 83 can be pushed and pulled alternately to achieve comprehensive polishing of the makeup brush surface without dead angles. When the makeup brush moves laterally, the ball bearing 93 will assist its movement and reduce friction on the makeup brush. When the makeup brush is stationary, the anti-slip pad 94 will fix the makeup brush to a certain extent. When the makeup brush is polished, it will rotate due to the inertia of the polishing ball 115. The anti-slip pad 94 can effectively prevent the makeup brush from rotating too fast and thus causing some parts to be missed during polishing.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
