Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic cotton processing, in particular to a cosmetic cotton production, processing and drying device. Background Art

[0002] The raw materials of cosmetic cotton are mainly pure cotton fiber, viscose fiber, absorbent cotton, etc. These raw materials have the characteristics of good water absorption and strong skin affinity. Therefore, cosmetic cotton is usually used to wipe the softer parts such as the face. Pour the makeup remover or makeup remover oil on the cosmetic cotton and then gently wipe the face, which can effectively dissolve and remove makeup, sunscreen and dirt.

[0003] When making cosmetic cotton pads, they need to be washed and then dried to ensure that they are dry and soft. Usually, the moisture inside the cosmetic cotton pads is squeezed out first, and then the cosmetic cotton pads are dried with hot air.

[0004] After long-term use and observation, it was found that squeezing the moisture inside the cotton pad by squeezing the pad may damage the internal structure of the cotton pad, causing the fibers to break or deform.

[0005] To this end, the utility model provides a cosmetic cotton production, processing and drying device. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specific examples are given below.

[0026] like Figures 1 to 5As shown, a cosmetic cotton production, processing and drying device described in an embodiment of the utility model comprises a drying box 1; a motor 11 is provided in the middle of the side wall of the drying box 1; a driving roller 12 is fixedly connected to the output end of the motor 11; a driven roller 13 is provided below the driving roller 12; the driving roller 12 and the driven roller 13 are of the same size; an electric push rod 14 is fixedly connected to the middle of the side wall of the drying box 1; the electric push rods 14 are a pair and are respectively arranged on both sides of the drying box 1; the electric push rods 14 are arranged between the driving roller 12 and the driven roller 13; a fixing frame 15 is fixedly connected to the output end of the electric push rod 14; an upper bracket 16 is fixedly connected to the middle of the side wall of the fixing frame 15; the upper bracket 16 is a pair and is symmetrically arranged on both sides of the fixing frame 15 side; the other end of the upper bracket 16 is fixedly connected to a metal mesh 18; the middle of the side wall of the fixing frame 15 is fixedly connected to a lower bracket 17; the lower bracket 17 is a pair and is symmetrically arranged on both sides of the fixing frame 15; the other end of the lower bracket 17 is fixedly connected to the metal mesh 18; a pair of feed ports 19 are opened in the middle of the side wall of the drying box 1; the pair of feed ports 19 are respectively arranged corresponding to the driving roller 12 and the driven roller 13; the bottom of the side wall of the metal mesh 18 is fixedly connected to a water baffle 110; the water baffle 110 is slidably connected to the side wall of the drying box 1; when working, the staff wraps the cosmetic cotton around the surface of the driving roller 12 and the driven roller 13, and then starts the motor 11, which drives the driving roller 12 to start rotating. At this time, the cotton is wrapped around The cosmetic cotton on the surface of the driving roller 12 will start to move, and the driven roller 13 will rotate synchronously with the driving roller 12 under the action of the driving roller 12 and the cosmetic cotton. When the cosmetic cotton to be dried moves between the pair of metal meshes 18, the motor 11 is turned off, and the cosmetic cotton stops moving. The staff can start the electric push rod 14 at any time, and the electric push rod 14 pushes the fixing frame 15, so that the upper bracket 16 and the lower bracket 17 fixed on the surface of the fixing frame 15 push the pair of metal meshes 18 to approach each other, so that the pair of metal meshes 18 squeeze the cosmetic cotton to be dried. In this step, the motor 11, the driving roller 12 and the driven roller 13 are set to fix the cosmetic cotton on the surfaces of the driving roller 12 and the driven roller 13. When 13 rotates, it pushes the cosmetic cotton wound on the surface of the driving roller 12 and the driven roller 13 to move, and the drying area of ​​the cosmetic cotton is changed by controlling the motor 11 to start and stop at will. The metal mesh 18 can squeeze out the moisture inside the cosmetic cotton by squeezing. Because the metal mesh 18 is a mesh structure, during the squeezing process, the moisture can flow out quickly and in large quantities through the mesh holes. At the same time, the surface of the metal mesh 18 is smooth and it is not easy to adhere to dirt or residue. After squeezing out water, the metal mesh 18 can be easily cleaned by rinsing or wiping to keep it in good working condition. By setting the water baffle 110, the situation that water will drip onto the cosmetic cotton to be dried below when the metal mesh 18 squeezes out the moisture inside the cosmetic cotton can be reduced.

[0027] Further, such as Figures 1 to 4As shown, an air storage box 2 is fixedly connected to the middle part of the side wall of the metal mesh 18; an air inlet pipe 21 is fixedly connected to the middle part of the side wall of the air storage box 2; the air inlet pipe 21 is slidably connected to the side wall of the drying box 1; an air outlet pipe 22 is fixedly connected to the bottom side wall of the air storage box 2; during operation, the staff connects the hot air blower to the air inlet pipe 21, and the hot air injected into the air inlet pipe 21 will stay in the air storage box 2, and then flow out from the air outlet pipe 22 and blow to the surface of the cosmetic cotton squeezed between a pair of metal meshes 18. In this step, by setting the air storage box 2, the air inlet pipe 21 and the air outlet pipe 22, the cosmetic cotton can be dried by blowing hot air to the surface of the cosmetic cotton. Hot air drying can dry the cosmetic cotton to an appropriate moisture content in a relatively short time, avoid the hardening or deformation of the cosmetic cotton caused by long-term high-temperature drying, and at the same time, because the hot air can quickly evaporate the moisture inside the cosmetic cotton, the cosmetic cotton can be kept dry and hygienic.

[0028] Further, such as Figure 2 and Figure 4 As shown, a first fixing rod 3 is fixedly connected to the middle part of the side wall of the metal mesh 18; a wind shield 31 is fixedly connected to the other end of the first fixing rod 3; a second fixing rod 32 is fixedly connected to the middle part of the side wall of the wind shield 31; there are multiple wind shields 31 and the sizes of the wind shields 31 decrease from bottom to top; the multiple wind shields 31 are connected by the second fixing rod 32; during operation, when the air outlet pipe 22 blows hot air to the surface of the cosmetic cotton, the multiple wind shields 31 will adjust the direction of the hot air blowing down from various angles. This step can change the direction of the hot air blowing straight downward by setting the first fixing rod 3, the wind shield 31 and the second fixing rod 32. When the hot air contacts the wind shields 31 at different positions, the flow direction will be changed, thereby increasing the contact area between the hot air and the cosmetic cotton, ensuring that all parts of the cosmetic cotton can be evenly supplied with hot air, thereby avoiding local over-drying or over-humidification.

[0029] Further, such as Figures 2 to 4As shown, the top side wall of the metal mesh 18 is provided with a groove 4; the grooves 4 are a pair and symmetrically arranged on the top of the metal mesh 18; a connecting rod 41 is fixedly connected to the middle of the inner side wall of the groove 4; a movable rod 42 is rotatably connected to the middle of the side wall of the connecting rod 41; a stretching block 43 is fixedly connected to the end of the movable rod 42; the movable rod 42 is connected to the connecting rod 41 with a torsion spring; when working, when a pair of metal meshes 18 squeeze the cosmetic cotton, the stretching block 43 will contact the cosmetic cotton and be pushed upward by the cosmetic cotton, and at this time the movement of the stretching block 43 will pull the metal The net 18 deforms outward because the movable rod 42 and the connecting rod 41 are connected by a torsion spring. When a pair of metal nets 18 are separated from the cosmetic cotton, the stretching block 43 returns to its original position and the metal net 18 also returns to its original state. This step sets the connecting rod 41, the movable rod 42 and the stretching block 43. When the stretching block 43 contacts the cosmetic cotton and moves upward, it stretches the metal net 18, causing the metal net 18 to deform, thereby increasing the contact area between the metal net 18 and the cosmetic cotton, so that the metal net 18 can squeeze the cosmetic cotton in a larger range, thereby improving the efficiency of the metal net 18 in squeezing out the cosmetic cotton.

[0030] Further, such as Figure 2 , Figure 4 and Figure 5 As shown, a heating block 5 is fixedly connected to the middle of the side wall of the upper bracket 16; there are multiple heating blocks 5 and they are evenly arranged on the side wall of the upper bracket 16; a heating lamp 51 is fixedly connected to the middle of the side wall of the heating block 5; when working, by controlling the multiple heating blocks 5, the heating lamp 51 on the side wall of the heating block 5 emits heat radiation to the outside, and the heat emitted by the heating lamp 51 will radiate to the surface of the cosmetic cotton. In this step, by setting the heating block 5 and the heating lamp 51, heat can be transferred to the cosmetic cotton by thermal radiation, so that the water molecules inside the cosmetic cotton can obtain energy and start to move, eventually causing the evaporation of water, and at the same time, the thermal radiation can penetrate into the interior of the cosmetic cotton, so that the interior and the surface are heated at the same time, further improving the drying efficiency of the cosmetic cotton.

[0031] Further, such as Figure 4 and Figure 5 As shown, a reflector 6 is fixedly connected to the middle of the side wall of the lower bracket 17; the reflector 6 is multiple and evenly arranged on the side wall of the lower bracket 17; the reflector 6 is made of smooth material; in this step, by setting the reflector 6 to be made of smooth material, the heat radiated to the surface of the reflector 6 can be reflected back to the surface of the cosmetic cotton, thereby reducing heat loss and increasing the utilization rate of thermal energy.

[0032] Working principle: the staff wraps the cosmetic cotton around the surfaces of the driving roller 12 and the driven roller 13, and then starts the motor 11. The motor 11 drives the driving roller 12 to start rotating. At this time, the cosmetic cotton wrapped around the surface of the driving roller 12 will start to move, and the driven roller 13 will rotate synchronously with the driving roller 12 under the action of the driving roller 12 and the cosmetic cotton. When the cosmetic cotton to be dried moves between a pair of metal meshes 18, the motor 11 is turned off, and the cosmetic cotton stops moving. The staff starts the electric push rod 14 at any time, and the electric push rod 14 pushes the fixing frame 15, so that the upper bracket 16 and the lower bracket 17 fixed to the surface of the fixing frame 15 push the pair of metal meshes 18 closer to each other, so that the pair of metal meshes 18 squeeze the cosmetic cotton to be dried. The staff connects the hot air blower to the air inlet pipe 21. At this time, the hot air injected into the air inlet pipe 21 will stay in the air storage box 2, and then from the air outlet pipe 22 flows out and blows toward the surface of the cosmetic cotton squeezed between a pair of metal meshes 18. When the air outlet pipe 22 blows hot air toward the surface of the cosmetic cotton, multiple wind shields 31 will adjust the direction of the hot air blowing down from various angles. When the pair of metal meshes 18 squeeze the cosmetic cotton, the stretching block 43 will contact the cosmetic cotton and be pushed upward by the cosmetic cotton. At this time, the movement of the stretching block 43 will pull the metal mesh 18 to deform outward. Because the movable rod 42 and the connecting rod 41 are connected by a torsion spring, when the pair of metal meshes 18 are separated from the cosmetic cotton, the stretching block 43 returns to its original position and the metal mesh 18 also returns to its original state. By controlling the multiple heating blocks 5, the heating lamp tube 51 on the side wall of the heating block 5 emits heat radiation to the outside. At this time, the heat emitted by the heating lamp tube 51 will radiate to the surface of the cosmetic cotton. By setting the reflector 6 to a smooth material, the heat radiated to the surface of the reflector 6 can be reflected back to the surface of the cosmetic cotton.
