Description

Technical Field

[0001] This utility model relates to the field of cosmetic production equipment technology, specifically to a splash-proof cosmetic soft tube filling device. Background Technology

[0002] In cosmetic packaging production lines, tube filling is a critical process. Automatic or semi-automatic filling equipment is typically used to quantitatively fill tubes with pastes, liquids, and other materials. During the filling process, splashing is highly likely to occur due to factors such as unstable pressure control, tube misalignment, or material rheological properties. This not only contaminates the filling area and equipment, compromising the cleanliness of the production environment and increasing cleaning and maintenance costs, but also causes unexpected losses of expensive cosmetic raw materials, directly driving up production costs. However, traditional equipment often lacks effective splash-proof designs, making it difficult to recover spilled material, failing to ensure cleanliness and resulting in resource waste. Utility Model Content

[0003] The purpose of this invention is to design a cosmetic tube filling device that can suppress filling splashes, ensure clean operation, and effectively collect overflow to reduce waste.

[0004] This utility model includes a hopper and a filling head disposed below the hopper. A sleeve is screwed to the lower part of the hopper, and at least one guide sleeve is fixed along the circumference of the lower part of the sleeve. Each guide sleeve is provided with a guide rod, and the upper end of each guide rod is fixedly connected to a guide ring sleeved outside the sleeve. Above the guide ring is a cylinder with its body fixed outside the sleeve, and the piston rod of the cylinder is fixedly connected to the guide ring. It also has a splash guard, the lower end of which has an outer protrusion larger than the size of the lower port of the sleeve. The lower ends of each guide rod are fixedly connected to the outer protrusion. The main body of the splash guard can be inserted into the sleeve through the lower port of the sleeve, and a filling head through hole is provided on its upper end face, through which the filling head can pass.

[0005] Furthermore, the filling head perforation is a stepped hole with a larger upper diameter and a smaller lower diameter. A wear-resistant ring is installed inside the filling head perforation. The inner diameter of the wear-resistant ring is smaller than the minimum diameter of the filling head perforation, and the wear-resistant ring is fixed to the stepped surface of the filling head perforation by bolts. The inner diameter of the wear-resistant ring is adapted to the diameter of the filling head.

[0006] Furthermore, the lower end of the splash cap has a base plate, on which a packaging tube fitting protrusion ring protrudes upward, and a drain hole is provided.

[0007] Furthermore, the inner wall of the sleeve is provided with an annular stroke groove, and a guide block or guide ring with a stroke groove is fixed on the side wall of the splash cap. The height of the stroke groove is adapted to the cylinder stroke.

[0008] The beneficial effects of this utility model are as follows: By setting a splash guard on the outside of the filling head and driving the splash guard to dock with the packaging tube fixing seat below the filling head through a guide rod, the splash guard achieves a sealing effect during filling. Under the action of the splash guard, the raw material splashes and contaminates the filling device. The raw material splashed onto the inner wall of the splash guard slides down the inner wall to the bottom plate, where it is collected by the packaging tube and the protruding ring. Then, the raw material can be recovered by connecting to the suction device through the drain hole. Thus, the filling splash is suppressed, the operation is kept clean, and the overflow is effectively collected to reduce waste. Attached Figure Description

[0015] Unless otherwise specified, the inner side of this embodiment is defined as the side closer to the central axis of the filling head 2, and the outer side is defined as the side farther from the central axis of the filling head 2. Figure 1 The diagram shows the up / down and left / right directions defined in this embodiment.

[0016] As shown in the figure, this embodiment includes a hopper 1 and a filling head 2 disposed below the hopper 1. The lower part of the hopper 1 and the filling head 2 are cylindrical and have threads on the outer surface. A sleeve 3 is screwed onto the lower part of the hopper 1 through the threads. The sleeve 3 is a cylindrical shape with openings at the top and bottom. At least one guide sleeve 301 is uniformly welded and fixed to the lower part of the sleeve 3 along the circumference of the outer surface. The guide sleeves 301 are most stable when they are symmetrically evenly arranged.

[0017] Each guide sleeve 301 is a cylindrical shape with openings at the top and bottom, and a dynamically fitted guide rod 4 is installed inside. The upper end of each guide rod 4 is fixed to the lower end face of the guide ring 5 that is sleeved outside the sleeve 3 by welding. Above the guide ring 5, a cylinder 6 is installed, with its cylinder body fixed to the upper outer surface of the sleeve 3. The piston rod of the cylinder 6 faces the guide ring 5 and is fixedly connected to the upper end face of the guide ring 5, which can be fixed by welding or bolts. The inner wall of the sleeve 3 is provided with an annular stroke groove 302, the height of which is adapted to the stroke of the cylinder 6.

[0018] This embodiment also includes a splash-proof cap 7, which is a cylindrical shape with an open lower end. The lower end of the splash-proof cap 7 has an outer protrusion 701 larger than the size of the lower port of the sleeve 3. The lower ends of each guide rod 4 are fixedly connected to the upper end face of the outer protrusion 701 by welding, and a sealing ring 709 is provided on the lower end face of the outer protrusion 701. The main body of the splash-proof cap 7 can be inserted into the sleeve 3 through the lower port of the sleeve 3. The upper end face of the splash-proof cap 7 is provided with a filling head through hole 702, through which the filling head 2 can pass.

[0019] The filling head perforation 702 is a stepped hole with a larger upper diameter and a smaller lower diameter. A wear-resistant ring 703 is provided inside the filling head perforation 702. The wear-resistant ring 703 is annular and its inner diameter is adapted to the diameter of the filling head 2. The wear-resistant ring 703 is fixed to the stepped surface of the filling head perforation 702 by bolts. The inner diameter of the wear-resistant ring 703 is smaller than the minimum diameter of the filling head perforation 702 to prevent the filling head 2 from contacting the splash cap 7 and causing wear. The detachable wear-resistant ring 703, which is fixed by bolts, fits well with the filling head 2. When the wear-resistant ring 703 is severely worn, it can be replaced in time, effectively ensuring the service life of the splash cap 7 and reducing costs.

[0020] In this embodiment, the inner wall of the sleeve 3 is provided with an annular travel groove 302. The side wall of the splash cap 7 is fixed with a guide block 704 or guide ring that cooperates with the travel groove 302. The guide block 704 or guide ring is fixed on the upper outer wall of the splash cap 7 by screws. If it is a guide block 704, it is adapted to the arc shape of the outer wall of the splash cap 7 and is symmetrically arranged in pairs on the upper outer surface side wall of the splash cap 7.

[0021] The lower end of the inner wall of the splash cap 7 is provided with a base plate 705. A packaging tube mating protrusion 706 is provided on the base plate 705, which protrudes upward from the upper end surface of the base plate 705. The packaging tube mating protrusion 706 is located on the inner edge of the base plate 705 and protrudes from the upper end surface of the base plate 705. The height of the packaging tube mating protrusion 706 is much smaller than the height of the splash cap 7. After docking with the packaging tube fixing seat, it is lower than or equal to the height of the upper end of the packaging tube 15.

[0022] The lower end face of the base plate 705 is flush with the lower end face of the outer protrusion 701 of the splash cap 7. The base plate 705 is provided with a drain hole 707. The drain hole 707 can be set between the side wall of the base plate 705 and the splash cap 7 and extend outward through the interior of the base plate 705 and the outer protrusion 701. The port of the drain hole 707 can be welded with a connector 708 for connecting the drain pipe 14. During use, the splashed raw materials can be recovered by existing suction devices to prevent resource waste.

[0023] In this embodiment, the packaging tube fixing seats are spaced apart on the conveying mechanism 12 below the hopper 1. The conveying mechanism 12 adopts existing technology and can be a circulating conveyor belt mechanism, a horizontal guide rail mechanism for precise forward and backward movement, or a circulating ring guide rail mechanism, etc., to realize the assembly line filling of the packaging tube 15. The left and right sides of the hopper 1 are fixedly connected to the existing vertical guide rail mechanism 13 to realize overall support and up and down movement.

[0024] The packaging tube fixing seat includes a cylindrical base 8 with an open top. A set of positioning sleeves 801 are symmetrically arranged on the outer circumference of the base 8. Each positioning sleeve 801 is a square tube with open ends and a positioning rod 9 is movably fitted inside. Each positioning sleeve 801 has a threaded hole on its outer side that communicates with its inner wall. The threaded hole is fitted with a fastening bolt 802, which can be used to position the positioning rod 9. A stabilizing ring 10 is provided above each positioning rod 9, and the upper end of each positioning rod 9 is fixedly connected to the lower end face of the stabilizing ring 10. The height of the stabilizing ring 10 can be adjusted by adjusting the positioning rod 9.

[0025] In this embodiment, the upper end face of the stabilizing ring 10 is provided with an annular groove 1002. The annular groove 1002 is adapted to the position and size of the sealing ring 709 provided on the lower end face of the outer protrusion 701 of the splash cap 7. A pair of elastic clamping pieces 1001 are symmetrically provided on the lower end face of the stabilizing ring 10 near the inner wall. After the packaging tube 15 is inserted, it can adapt to the upper outer wall of the packaging tube 15 to support it firmly, ensuring that the upper end of the packaging tube 15 is vertically upward. The upper end of the packaging tube 15 is higher than the upper end face of the stabilizing ring 10.

[0026] The base 8 of the packaging tube fixing seat is symmetrically equipped with clamping mechanisms 11 that penetrate the inner wall of the base 8. The horizontal axis of the clamping mechanism 11 is perpendicular to the horizontal axis of the elastic clamping piece 1001, thereby clamping the lower part of the packaging tube 15. In conjunction with the elastic clamping piece 1001, it can stably clamp packaging tubes 15 of different thicknesses. The clamping mechanism 11 adopts existing technology and will not be described in detail here.

[0027] In this embodiment, the height of the stabilizing ring 10 is first adjusted by adjusting the positioning rod 9 according to the length specification of the packaging tube 15 to be filled. After the adjustment is in place, the positioning rod 9 is fixed by the fastening bolt 802 and the stabilizing ring 10 is locked at the required height. Then the packaging tube 15 is placed into the packaging tube fixing seat, and the packaging tube 15 is firmly clamped by the clamping mechanism 11 and the elastic clamping piece 1001.

[0028] Subsequently, the conveying mechanism 12 drives the packaging tube fixing seat and packaging tube 15 to move directly below the filling head 2. After the detection system identifies the position, the hopper 1 moves down through the vertical guide rail mechanism 13, so that the filling head 2 is accurately inserted into the opening of the packaging tube 15. When the filling head 2 is in position, the guide ring 5 moves downward under the drive of the cylinder 6, and its guide rod 4 drives the splash cap 7 to move down synchronously. During this process, the guide block 704 on the outer wall of the splash cap 7 cooperates with the stroke groove 302 on the inner wall of the sleeve 3, and with the cooperation of the guide rod 4 and the guide sleeve 301, the splash cap 7 and the stabilizing ring 10 are connected. After the position is in place, the filling begins. Under the action of the splash cap 7, the filling splash is effectively suppressed and the operation is kept clean. The raw material splashed onto the inner wall of the splash cap 7 slides down the inner wall to the bottom plate 705. The raw material is collected by the packaging tube and the protruding ring 706. Then, the raw material can be recovered by connecting to the suction device through the drain hole 707, thereby effectively collecting the overflow to reduce waste.

[0029] Structures not specifically described in this embodiment are all existing technologies and will not be elaborated upon here. This invention is not only applicable to flexible tubes but can also be used for filling cylindrical tubes of other materials. When the packaging tube is a flexible tube, the stiffness of its elastic clamping piece must be less than the hardness of the flexible tube to ensure a secure fit without deforming the packaging tube.
