Description

Technical Field

[0001] This utility model relates to the field of mascara filling, specifically a mascara filling head. Background Technology

[0002] Common mascara bottles are typically automated containers with a built-in brush and a thin stick, containing a cream or liquid product. Since mascara bottles are usually long and narrow cylinders with a small opening, the filling head must be inserted into the bottle opening during filling. There is usually a gap between the filling head and the inner wall of the bottle opening. Because the gap is small, when the mascara is quickly injected into the bottle, air inside the bottle is quickly expelled through the gap between the filling head and the inner wall of the bottle opening. At this time, the air flow rate in the gap is fast, and some of the mascara flowing out of the filling head will overflow the bottle opening due to the airflow, thus contaminating the mascara filling equipment. Utility Model Content

[0003] The purpose of this invention is to provide a mascara filling head that overcomes the aforementioned defects in the prior art.

[0004] According to the present invention, a mascara filling head includes a straight tube with a connector fixed at the upper end of the straight tube. The filling section is fixed at the lower end of the straight tube, and a plurality of radially recessed ventilation grooves are formed on the lower peripheral wall of the filling section. The diameter of the outer circumference circle of the outer peripheral wall of the filling section gradually increases from bottom to top.

[0005] Through the above technical solution, the ventilation groove recessed towards the axis of the filling section allows for an exhaust channel between the outer periphery of the filling section and the inner wall of the bottle mouth when the filling section is inserted into the bottle mouth of the mascara filling bottle. This allows the air inside the filling bottle to be discharged through the exhaust channel during mascara filling. The large airflow and low velocity in the exhaust channel can reduce the overflow of mascara from the bottle mouth.

[0006] Furthermore, a clamping member is detachably fixed to the outer periphery of the straight tube, and two connecting rods are fixed on the clamping member located on its lower side. The two connecting rods are symmetrically arranged with the filling section as the center. An arc plate is fixed to the lower end of the connecting rod, and a positioning part extends radially outward from the lower edge of the arc plate. The positioning part can abut against the shoulder of the mascara filling bottle. The distance between the lower end face of the positioning part and the lower end of the filling section is less than the distance between the bottle mouth and the bottle shoulder.

[0007] The above technical solution facilitates the positioning of the lower end of the filling section with the bottle mouth of the filling bottle.

[0008] Furthermore, the clamping member includes two symmetrically arranged fixing plates, with a sleeve plate fixedly mounted on the upper surface of the fixing plates. The two fixing plates form a ring, and the two sleeve plates form a cylinder. The connecting rod is fixed to the lower surface of the fixing plates. Connecting plates are fixedly mounted on the sides of both the fixing plates and the sleeve plates, and the two connecting plates are fixedly connected by bolts.

[0009] The above technical solution facilitates the assembly and disassembly of the clamping component and the straight pipe.

[0010] Furthermore, a clamp is fixedly provided on the lower end face of the positioning part, and one side of the clamp near the axis of the filling section abuts against the outer periphery of the mascara filling bottle.

[0011] The above technical solution enables the bottle opening to be aligned with the filling section when the two clamps hold the mascara filling bottle.

[0012] Furthermore, a guide portion is fixedly provided on the lower edge of the clamping plate, and the guide portion is inclined outward from top to bottom.

[0013] The above technical solution allows the guide section to guide the filling bottle to the lower side of the filling section when the clamp moves downward.

[0014] Furthermore, the connecting rod is made of stainless steel and has elastic deformation capability.

[0015] Through the above technical solution, the connecting rod is designed so that the arc plate can be bent away from the axis of the filling section, thereby enabling the two clamping plates to hold filling bottles of different diameters.

[0016] Furthermore, a positioning ring is fixed on the outer periphery of the straight pipe, and the upper end face of the sleeve plate abuts against the positioning ring.

[0017] Through the above technical solution, when the positioning part comes into contact with the bottle shoulder, the positioning ring can effectively prevent the sleeve from shifting and ensure accurate positioning.

[0018] The beneficial effects of this utility model are: the ventilation groove recessed towards the axis of the filling section makes an exhaust channel between the outer periphery of the filling section and the inner wall of the bottle mouth when the filling section is inserted into the bottle mouth of the mascara filling bottle. This allows the air in the filling bottle to be discharged from the exhaust channel during the filling of mascara. The air flow rate in the exhaust channel is large and the flow velocity is small, which can reduce the overflow of mascara from the bottle mouth. Attached Figure Description

[0029] To make the objectives and advantages of this utility model clearer, the following detailed description of the utility model is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up and down and left and right are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. The specific features of this mascara filling head are described in detail below:

[0030] One embodiment of this utility model:

[0031] Reference Figures 1-7This utility model provides a mascara filling head, including a straight tube 10, with a connector 20 fixed at the upper end of the straight tube 10. The feature is that a filling section 11 is fixed at the lower end of the straight tube 10, and a plurality of radially recessed ventilation grooves 111 are formed on the lower peripheral wall of the filling section 11. The diameter of the outer circumference circle of the outer peripheral wall of the filling section 11 gradually increases from bottom to top.

[0032] Reference Figure 5 A clamping component is detachably fixed on the outer periphery of the straight tube 10. Two connecting rods 31 are fixed on the clamping component and located on its lower side. The two connecting rods 31 are symmetrically arranged with the filling section 11 as the center. An arc plate 32 is fixed at the lower end of the connecting rod 31. A positioning part 321 extends radially outward from the lower edge of the arc plate 32. The positioning part 321 can abut against the shoulder of the mascara filling bottle. The distance between the lower end face of the positioning part 321 and the lower end of the filling section 11 is less than the distance between the bottle mouth and the bottle shoulder.

[0033] Reference Figure 5 The clamping component includes two symmetrically arranged fixing plates 30. A sleeve plate 34 is fixed on the upper end surface of the fixing plate 30. The two fixing plates 30 form a ring, and the two sleeve plates 34 form a cylinder. A connecting rod 31 is fixed on the lower end surface of the fixing plate 30. A connecting plate 301 is fixed on the side of both the fixing plate 30 and the sleeve plate 34. The two connecting plates 301 are fixedly connected by bolts.

[0034] Reference Figure 5 A clamping plate 33 is fixedly provided on the lower end face of the positioning part 321, and one side of the clamping plate 33 near the axis of the filling section 11 abuts against the outer periphery of the mascara filling bottle.

[0035] Reference Figure 3 , Figure 5 A guide portion 331 is fixedly provided on the lower edge of the clamping plate 33, and the guide portion 331 is inclined outward from top to bottom.

[0036] Reference Figure 5 The connecting rod 31 is made of stainless steel and has elastic deformation capability.

[0037] Reference Figure 5 , Figure 6 A positioning ring 12 is fixed on the outer periphery of the straight pipe 10, and the upper end face of the sleeve plate 34 abuts against the positioning ring 12.

[0038] In use, the connector 20 is fixed to the mascara filling equipment and moves up and down with the filling equipment.

[0039] During filling, after the mascara bottle moves to the lower side of the filling section 11 with the conveying device, the present invention moves downward with the filling equipment, thereby causing the clamping plate 33 to move downward. When the bottle shoulder of the filling bottle abuts against the guide part 331, due to the inclined setting of the guide part 331, the filling bottle moves to directly below the filling section 11 until the two clamping plates 33 are fitted onto the bottle body, thereby ensuring that the bottle mouth and the lower end of the filling section 11 are aligned.

[0040] After the positioning part 321 abuts against the shoulder of the filling bottle, the lower end of the filling section 11 is inserted into the bottle mouth. Then the filling equipment is started, and the paste is injected into the filling bottle along the straight tube 10 and the filling section 11. After a certain volume is filled, the filling equipment is turned off. The present invention moves upward with the filling equipment until the guide part 331 is located on the upper side of the filling bottle.

[0041] During this process, the friction between the inner side of the clamp 33 and the bottle body is less than the weight of the bottle body, so that when the clamp 33 is lifted off the filling bottle, the filling bottle remains on the conveying device.

[0042] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
