Description

Technical Field

[0001] This utility model relates to the field of cosmetic production equipment technology, specifically a cosmetic anti-powder inner plug installation device. Background Technology

[0002] In the cosmetics manufacturing industry, especially in the assembly process of powder cosmetics, the powder is usually first filled into the cosmetic case, and then an inner plug is installed to achieve a seal. The conventional inner plug installation process often uses a vertical alignment method, that is, a mechanical device presses the inner plug into the cosmetic case from top to bottom, directly opposite the opening. However, this installation method has significant technical drawbacks in actual operation.

[0003] Once the inner plug descends and comes into contact with the opening of the cosmetic case, if pressure continues to be applied to secure it completely, the volume of the internal cavity of the cosmetic case will rapidly decrease due to the compression of the inner plug, resulting in a significant increase in the gas pressure inside the case. Since there is usually a tiny gap between the outer wall of the inner plug and the inner wall of the cosmetic case, the high-pressure airflow will escape outwards along this gap. This high-speed outward airflow will interact with the powder already filled inside the case, carrying some fine powder particles with it, causing powder scattering and loss.

[0004] Powder scattering not only directly leads to insufficient product filling and affects yield, but can also pollute production equipment and the surrounding environment, increasing cleaning and maintenance costs. Furthermore, if scattered powder adheres to the exterior of cosmetic cases or sealing surfaces, it can further affect the product's appearance and sealing reliability.

[0005] Therefore, there is an urgent need for a method that can balance the air pressure inside and outside the cosmetic box during the installation of the inner plug, so as to improve the process quality and production efficiency of powder cosmetic assembly. Utility Model Content

[0006] To address the technical problems in the background art, this utility model discloses a cosmetic anti-powder inner plug installation device.

[0007] This utility model provides a cosmetic anti-powder inner plug installation device for fixing the inner plug to a cosmetic box. During installation, the inner plug abuts against the opening of the cosmetic box, and includes a squeezing member that applies pressure to the inner plug. The inner plug is subjected to pressure from the extruder, extending from one end to the other. When one end of the inner plug is under pressure, it is arranged at an angle; as the pressure extends to the other end of the inner plug, the slope of the inner plug decreases.

[0008] Furthermore, the end of the inner plug that is preferentially subjected to the pressure of the extruder is the end that moves in the direction of the inner plug.

[0009] Furthermore, the lower end face of the extrusion is arranged at an angle, with the end in the direction of the inner plug movement being the lower end and the end in the direction of the inner plug movement being the higher end.

[0010] Furthermore, the extrusion component is a belt, which is driven by a drive motor to move in a ring. The lower part of the extruder moves in the same direction as the inner plug, and at the same speed.

[0011] Furthermore, the belt is installed inside the fixed box; The fixed box is equipped with a first end pulley and a second end pulley at each end of the belt; Multiple linearly arranged, belt-engaging intermediate pulleys are provided between the first end pulley and the second end pulley; The straight line formed by the positions of the central wheels is arranged at an angle.

[0012] Furthermore, the first end wheel is connected to the fixed box through an elongated hole arranged horizontally on the fixed box, so that the horizontal position of the first end wheel can be adjusted.

[0013] Furthermore, the first end wheel is rotatably connected to the fixed box via the first rotating shaft; The end of the first rotating shaft is rectangular and is snapped into an oblong hole; The end of the first shaft, the part located inside the elongated hole, is provided with a horizontally arranged threaded hole. The bolt passes through the fixed box and is threaded into the threaded hole.

[0014] Furthermore, it also includes an adjustment component that can drive the fixed box to rise and fall.

[0015] Furthermore, the adjustment assembly includes guide posts; The fixed box is equipped with a guide sleeve for connecting guide posts; A top plate is fixedly connected to the upper end of the guide post; The top plate is equipped with a rotatable lead screw; The upper end of the fixed box is fixedly equipped with a screw nut that is threadedly connected to the screw.

[0016] The beneficial effects of this invention are as follows: Through the inclined and progressive pressing design, the inner plug is not inserted vertically and synchronously as a whole during installation. Instead, it is tilted and gradually pressed flat from one end. This asymmetrical pressing method creates an opening between the other end of the inner plug and the cosmetic box, allowing air inside the cosmetic box to escape through this opening during the pressing process. This maintains stable air pressure inside the cosmetic box and prevents the internal cavity gas from being drastically compressed due to the inner plug instantly closing the cosmetic box opening. This significantly reduces the possibility of high-pressure airflow being ejected at high speed from the assembly gap, fundamentally solving the problem of powder particles being scattered by airflow, ensuring sufficient powder content, and improving product yield.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] like Figure 1-5 As shown, this utility model discloses a cosmetic anti-powder inner plug installation device, which is used to fix the inner plug 1 to the cosmetic box 2. During installation, the inner plug 1 first abuts against the opening of the cosmetic box 2, including a squeezing member that applies pressure to the inner plug 1; the inner plug 1 is subjected to the pressure of the squeezing member and extends from one end to the other end. When one end of the inner plug 1 is subjected to pressure, it is arranged at an angle; when the pressure extends to the other end of the inner plug 1, the slope of the inner plug 1 decreases.

[0021] The specific structure and installation structure of the extruded part are as follows: The device includes a rectangular fixing box 5, which is composed of an upper plate 52, a side plate 53, and an end plate 54. The upper plate 52 is arranged horizontally; the side plate 53 is arranged vertically and extends along the length of the upper plate 52, with the upper end of the side plate 53 connected to both ends of the lower end face of the upper plate 52 in the width direction; the end plate 54 is arranged vertically and extends along the width direction of the upper plate 52, with both ends of the end plate 54 connected to the side plate 53 in the horizontal direction, thereby forming a rectangular frame with the end plate 54 and the side plate 53.

[0022] Inside the fixed housing 5, a first end wheel 6 and a second end wheel 7 are respectively installed at both ends along its length. The first end wheel 6 has a first rotating shaft 61 rotatably connected via bearings, and both ends of the first rotating shaft 61 are fixedly connected to the side plate 53. The second end wheel 7 has a fixed second rotating shaft 71, the end of which is inserted into a bearing mounted on the side plate 53 for rotatable connection. A drive motor 4 is installed on the outer side of one of the side plates 53, and its driving end is fixedly connected to one end of the second rotating shaft 71 inside the second end wheel 7. When the drive motor 4 starts, it drives the second end wheel 7 to rotate, thereby driving the belt 3 to move in a ring. In this embodiment, the drive motor 4 is a combination of a motor and a geared motor, the belt 3 is a synchronous belt, and the first end wheel 6 and the second end wheel 7 are synchronous pulleys.

[0023] like Figure 7 As shown, a horizontally arranged elongated hole 51 is provided at the position where the first end wheel 6 is installed on the side plate 53. The end of the first rotating shaft 61 is rectangular and is inserted into the elongated hole 51, allowing the position of the first end wheel 6 to be adjusted to tension the belt 3. Furthermore, the structure at the end of the first rotating shaft 61 also serves as a guide for the movement of the first end wheel 6, making its movement more stable. A threaded hole 62 is provided at the part of the first rotating shaft 61 located within the elongated hole 51, extending along the length of the elongated hole 51. A through hole 55 is provided at the end of the side plate 53, communicating with one end of the elongated hole 51; this through hole 55 is a smooth hole. A bolt passes through the through hole 55 and is threaded into the threaded hole 62. By tightening the bolt, the first end wheel 6 can be driven to move outward, tensioning the belt 3.

[0024] Inside the fixed box 5, between the first end wheel 6 and the second end wheel 7, there are also multiple linearly arranged intermediate wheels 8. The intermediate wheels 8 are also synchronous pulleys and mesh with the lower part of the belt 3. The height of the intermediate wheels 8 decreases along the moving direction of the cosmetic box 2, so that the lower part of the belt 3 is inclined and the height of the lower end face of the belt 3 also decreases along the moving direction of the cosmetic box 2.

[0025] by Figure 2 For reference, the makeup box 2 is moved to the right, the lower end of the belt 3 is higher on the left and lower on the right, and the lower part of the belt 3 also moves to the right. For example... Figure 8 As shown, when the cosmetic box 2 moves to the point where the right end of the inner plug 1 contacts the belt 3, the right end of the inner plug 1 is subjected to pressure from the belt 3. As the cosmetic box 2 continues to move to the right, the right end of the inner plug 1 moves downward, while the left end tilts upward. The left end of the inner plug 1 and the left side of the cosmetic box 2 form a funnel-shaped opening that communicates with the outside. During the insertion of the inner plug 1, the air inside the cosmetic box 2 can be discharged through this opening, thereby maintaining a stable air pressure inside the cosmetic box 2.

[0026] If relative sliding occurs between the belt 3 and the inner plug 1, the inner plug 1 is prone to misalignment and detachment from the cosmetic box 2. Therefore, the moving speed of the belt 3 is the same as the moving speed of the inner plug 1, so that the belt 3 and the inner plug 1 remain relatively stationary when in contact.

[0027] Since the cosmetic box 2 comes in various models, the height of the inner plug 1 also varies. Therefore, this embodiment also includes an adjustment component to adjust the height of the belt 3. The adjustment component includes four vertically arranged guide posts 14, which form a rectangle. Their lower ends are fixedly connected to the ground, and their upper ends are connected via the top plate 10. A guide sleeve 9 is fixedly connected to the upper plate 52, and the guide sleeve 9 fits onto the guide posts 14 to guide the lifting and lowering of the fixed box 5. In this embodiment, the guide sleeve 9 is a linear bearing.

[0028] like Figure 6 As shown, a bearing housing 15 is fixedly installed on the top plate 10, and a thrust ball bearing 16 and a deep groove ball bearing 17 are installed inside the bearing housing 15. The upper end of the lead screw 11 is inserted into the bearing and extends upwards, then inserted into the handwheel 13 and fixedly connected to the handwheel 13. Driving the handwheel 13 will cause the lead screw 11 to rotate around its axis. Moreover, the lead screw 11 will not undergo axial displacement when rotating.

[0029] An upwardly extending connector 18 is fixedly installed on the upper end of the upper plate 52. A screw nut 12, which is threadedly connected to the screw 11, is fixedly connected to the upper end of the connector 18. When the screw 11 rotates, it can drive the fixed box 5 to rise and fall. The connector 18 is hollow, and the lower end of the screw 11 is inserted into the connector 18, thereby providing sufficient space for the screw 11 to be accommodated when the fixed box 5 is raised and lowered.

[0030] Compared to existing technologies, the advantages of this embodiment are: through a tilted, progressive pressing design, the inner plug 1 is not inserted vertically and synchronously as a whole during installation, but rather it begins to tilt and gradually flatten from one end. This asymmetrical pressing method creates an opening between the other end of the inner plug 1 and the cosmetic box 2, allowing air inside the cosmetic box 2 to escape through this opening during the pressing process. This maintains stable air pressure inside the cosmetic box 2 and prevents the inner plug 1 from instantly sealing the opening of the cosmetic box 2, which would cause the internal cavity gas to be rapidly compressed. This significantly reduces the possibility of high-pressure airflow being ejected at high speed from the assembly gap, fundamentally solving the problem of airflow carrying powder particles and ensuring sufficient powder content, thus improving the product yield.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
