Description

Technical Field

[0001] The utility model relates to the technical field of daily chemical product processing equipment, and more specifically to a lotion filling equipment. Background Art

[0002] In the field of cosmetics, lotion is a relatively common skin care product. Lotion has a high water content and can fully replenish moisture for the skin. It is generally a milky fluid with a certain viscosity. After it is circulated to the market, it is usually packaged and sold in cans.

[0003] The existing Chinese utility model patent with announcement number CN218754971U discloses an emulsion filling device, including a base, a lifting plate is arranged above the base, a liquid injection tube is fixedly installed at the bottom of the lifting plate, and the interior of the liquid injection tube is a cylindrical cavity structure, and an infusion hole connected with its inner cavity is arranged at the bottom of the liquid injection tube, and the infusion hole is a circular structure. When the infusion tube is separated from the bottle mouth, the cylinder will push the piston to drop rapidly by 0.5-1cm with the cooperation of the piston rod, and most of the emulsion that is concentrated on the inner side and lower edge of the infusion hole and sticks to the bottle will be blown into the bottle under the impact of air pressure, and then the cylinder will drive the piston to rise and return to its position rapidly. Similarly, under the action of negative pressure, the residual emulsion that is sticky on the inner side and lower edge of the infusion hole will be sucked into the inner side of the infusion hole. At this time, the annular groove can collect and retain these residual emulsions, thereby preventing the emulsion from directly flowing down through the smooth inner wall, and facilitating the next infusion, effectively preventing the emulsion from drawing and dripping, and making the production more perfect.

[0004] The above-mentioned canning equipment is provided with an annular concave platform surrounding the outer edge of the infusion hole at the bottom of the inner cavity of the infusion tube. The emulsion remaining on the inner wall of the infusion tube will slowly flow into the annular concave platform, playing a role of drip buffer. However, the emulsion will remain in the annular concave platform for a long time, which is easy to breed bacteria and affect product quality. Utility Model Content

[0005] The utility model aims to provide an emulsion filling device to prevent the long-term residue of the emulsion from causing bacteria to grow and affecting product quality.

[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A lotion filling device comprises a liquid injection tube and a cylinder, wherein a liquid infusion tube is connected to the side wall of the liquid injection tube, a liquid outlet nozzle is connected to the bottom of the liquid injection tube, the bottom of the inner cavity of the liquid injection tube is a hemispherical recess, a valve stem is movably connected to the top of the liquid injection tube, the bottom of the valve stem is located on the inner side of the liquid injection tube and is fixedly connected to a valve core, the bottom of the valve core is a hemispherical body matched with the hemispherical recess, an ejection part is fixedly connected to the bottom of the valve core, the ejection part is an inverted cone, a liquid outlet channel connected to the liquid outlet nozzle is opened on the hemispherical recess, the size of the liquid outlet channel matches the ejection part, the top of the valve core is located on the outer side of the liquid injection tube and is connected to the output end of the cylinder.

[0008] Furthermore, the infusion tube is arranged to be inclined upward along the feeding direction.

[0009] Furthermore, an annular rod is provided at the bottom of the injection tube surrounding the liquid outlet, and the annular rod is fixedly connected to the bottom of the injection tube through a connecting rod. A plurality of rotating sleeves are rotatably provided on the annular rod, and a fan-shaped rubber sheet is fixedly connected to the rotating sleeve. The plurality of fan-shaped rubber sheets can jointly seal the liquid outlet.

[0010] Furthermore, an air flow channel is opened in the valve stem, one end of the air flow channel extends to the bottom end of the ejection portion, and the other end of the air flow channel extends to the outside of the top end of the valve stem and is connected to a three-way pipe.

[0011] Furthermore, a three-way valve is installed on the three-way pipe.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The cylinder pushes the valve core down, and the emulsion in the injection tube is injected into the emulsion container bottle through the liquid outlet nozzle. Then the cylinder drives the valve core to rise and return to its original position rapidly, so that negative pressure is formed in the injection tube. The emulsion at the end of the liquid outlet nozzle flows back into the injection tube under the action of negative pressure, which can effectively prevent drawing and dripping. By setting the hemispherical concave part, it can avoid the long-term residue of emulsion to cause bacterial growth, which affects the product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figures 1 to 4 As shown, a lotion filling equipment comprises a liquid injection tube 1 and a cylinder 2, a liquid infusion tube 3 is connected to the side wall of the liquid injection tube 1, a liquid outlet nozzle 4 is connected to the bottom of the liquid injection tube 1, the bottom of the inner cavity of the liquid injection tube 1 is a hemispherical recess 101, a valve stem 5 is movably connected to the top of the liquid injection tube 1, the bottom of the valve stem 5 is located on the inner side of the liquid injection tube 1 and is fixedly connected to a valve core 6, the bottom of the valve core 6 is a hemispherical body matched with the hemispherical recess 101, an ejection portion 7 is fixedly connected to the bottom of the valve core 6, the ejection portion 7 is an inverted cone, a liquid outlet channel 102 connected to the liquid outlet nozzle 4 is opened on the hemispherical recess 101, the size of the liquid outlet channel 102 matches the ejection portion 7, the top of the valve core 6 is located on the outer side of the liquid injection tube 1 and is connected to the output end of the cylinder 2.

[0020] The infusion tube 3 is arranged to tilt upward along the feeding direction; the infusion tube 3 is arranged to tilt upward to prevent part of the emulsion in the infusion tube 3 from flowing into the injection tube 1 and accumulating on the upper side of the valve core 6 when the valve core 6 moves to the bottom of the inner side of the injection tube 1.

[0021] A ring rod 8 is provided at the bottom of the injection tube 1 around the liquid outlet nozzle 4, and the ring rod 8 is fixedly connected to the bottom of the injection tube 1 through a connecting rod 9. A rotatable sleeve 10 is provided on the ring rod 8, and a plurality of rotating sleeves 10 are fixedly connected to the rotating sleeve 10. The plurality of fan-shaped rubber sheets 11 can jointly block the liquid outlet nozzle 4.

[0022] An air flow channel 501 is provided in the valve stem 5, one end of the air flow channel 501 extends to the bottom end of the ejection portion 7, and the other end of the air flow channel 501 extends to the outside of the top end of the valve stem 5 and is connected to a three-way pipe 12; a three-way valve is installed on the three-way pipe 12.

[0023] Working principle:

[0024] The air flow channel 501 is connected to the external air extraction device and the air supply device through the three-way pipe 12, and the valve core 6 is pushed down by the cylinder 2 to inject the lotion in the injection tube 1 into the lotion container bottle through the liquid outlet nozzle 4. After the injection is completed, gas is injected into the air flow channel 501 through the three-way pipe 12 to blow the lotion attached to the liquid outlet nozzle 4 into the lotion container bottle. Then the cylinder 2 will drive the valve core 6 to rise and return to its position quickly, so that negative pressure is formed in the injection tube 1. At the same time, air is sucked into the air flow channel 501 through the three-way pipe 12, so that the lotion remaining at the end of the liquid outlet nozzle 4 is discharged under the action of negative pressure. At the same time, the fan-shaped rubber sheet 11 is close to the liquid outlet nozzle 4 under the action of negative pressure, and together blocks the liquid outlet nozzle 4, so that a pressure difference is formed inside and outside the liquid outlet nozzle 4, and the fan-shaped rubber sheet 11 is kept blocking the liquid outlet nozzle 4, so as to avoid the air circulation inside and outside the liquid outlet pipe 1. The negative pressure disappears during the filling waiting interval, and the emulsion drips outward through the liquid outlet nozzle 4. When the cylinder 2 pushes the valve core 6 down again, the air in the liquid injection pipe 1 is compressed to form a positive pressure, which pushes the fan-shaped rubber sheet 11, so that the emulsion can flow out through the liquid outlet nozzle 4.
