Description

Technical Field

[0001] The utility model relates to the technical field of brush head production auxiliary structures, in particular to an automatic dotting auxiliary structure for a lip glaze brush head. Background Art

[0002] Lip gloss is a type of lip cosmetics. It is a liquid lipstick that is moisturizing, shiny, and easy to apply. When using it, it needs to be applied to the lips with a brush. The lip gloss brush usually includes a plastic rod and a brush head. During processing, the plastic brush head is usually fixed and inserted into the groove at the end of the plastic rod, and then the two are fixed together by dotting to prevent the brush head from falling off the end of the brush rod.

[0003] The principles of existing automatic dotting mechanisms for brush heads are relatively similar, that is, the loading function is realized through a turntable, and the assembled brush rod and brush head are inserted into the fixed groove of the turntable and transported to the designated position for dotting and fixing by a dotting machine. In this process, since the brush rod and brush head always follow the movement of the turntable and are affected by inertia, and it is difficult to ensure that the rod body is completely vertical during manual plug-in and installation, the rod body may tilt and offset when the brush rod moves to the dotting position, which eventually leads to dotting position offset or dotting failure. Therefore, in view of the above problems, an automatic dotting auxiliary structure for lip glaze brush heads is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an automatic dotting auxiliary structure for a lip glaze brush head, the brush head production auxiliary structure can fix and install lip glaze brushes with different cap sizes through a size-adjustable clamp, when the turntable rotates to transport the brush rod to the dotting position, the brush rod will pass through the constraint groove, and will be straightened and corrected by the inner constraint semi-ring and the outer constraint semi-ring, when the brush rod reaches the specified position, the electric telescopic rod pushes the tapered straightening fork forward, straightens and corrects the brush rod in a direction perpendicular to the previous straightening direction, ensuring that the brush rod to be dotted does not deviate, thereby ensuring the dotting effect, and solving the technical problem in the prior art that the brush rod and brush head always follow the movement of the turntable and are affected by inertia, and it is difficult to ensure that the rod body is completely vertical during manual plug-in installation, and when the brush rod moves to the dotting position, the rod body may be tilted and offset, which ultimately leads to dotting position offset or dotting failure.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0012] In a possible implementation, guide openings are provided at the ends of the inner constraint semi-ring and the outer constraint semi-ring, and a tapered fork opening is provided at the front of the tapered-opening righting fork.

[0013] Through the above-mentioned structural form, the setting of the guide mouth can guide the brush rod before it enters the constraint groove, so that the brush rod can smoothly enter the groove, and the structural form of the tapered fork mouth can squeeze and straighten the offset brush rod through the tapered inner walls on both sides during the continuous forward movement of the tapered mouth straightening fork.

DETAILED DESCRIPTION

[0033] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0034] like Figure 1 - Figure 2 As shown, a lip gloss brush head automatic dotting auxiliary structure provided in this embodiment includes a base plate 1, a rotating platform 2 and an anti-deflection correction mechanism 4, on which six size-adjustable clamps 3 distributed in a circular array are fixedly installed, wherein the anti-deflection correction mechanism 4 includes an inner constraint semi-ring 41 and an outer constraint semi-ring 42 located above the rotating platform 2, and a constraint groove is formed between the two, and a tapered straightening fork 44 is slidably arranged at the lower middle part of the inner constraint semi-ring 41 and the outer constraint semi-ring 42, and a tapered straightening fork 44 is arranged at the rear side thereof with a back side thereof. The connected electric telescopic rod 45 is used to fix and install lip gloss brushes of different cap sizes through the size-adjustable clamp 3. When the rotating table 2 rotates to transport the brush rod to the dotting position, the brush rod will pass through the constraint groove and will be straightened and corrected by the inner constraint semi-ring 41 and the outer constraint semi-ring 42. When the brush rod reaches the designated dotting position, the electric telescopic rod 45 pushes the tapered straightening fork 44 forward to straighten and correct the brush rod in a direction perpendicular to the previous straightening direction, ensuring that there is no obvious deviation of the brush rod to be dotted, thereby ensuring the dotting effect.

[0035] like Figure 2 As shown, two symmetrically arranged triangular support frames 46 are fixedly provided on the base plate 1, and the inner constraint semi-ring 41 and the outer constraint semi-ring 42 are fixedly connected by a U-shaped connecting frame 43, and the end of the U-shaped connecting frame 43 is fixedly connected to the top of the triangular support frame 46. This structural form can play a role in fixing and installing the inner constraint semi-ring 41 and the outer constraint semi-ring 42, and provide the necessary structural basis for their normal functions.

[0036] In addition, a mounting cross plate 47 is fixedly provided on the rear end surface of the triangular support frame 46, and the electric telescopic rod 45 is fixedly installed on the mounting cross plate 47. An inclined support rod 48 is fixedly connected between the mounting cross plate 47 and the triangular support frame 46. This structural form provides the necessary structural foundation for the fixed installation of the electric telescopic rod 45 with the mounting cross plate 47, and the setting of the inclined support rod 48 can ensure the stability of the mounting cross plate 47.

[0037] like Figure 6 As shown, guide openings 401 are provided at the ends of the inner constraint semi-ring 41 and the outer constraint semi-ring 42, and a tapered fork opening 441 is provided at the front of the tapered fork 44. Through the above-mentioned structural form, the setting of the guide opening 401 can guide the brush rod before it enters the constraint groove, so that the brush rod can smoothly enter the groove, and the structural form of the tapered fork opening 441 can squeeze and straighten the offset brush rod through the tapered inner walls on both sides during the continuous forward movement of the tapered fork 44.

[0038] like Figure 3-Figure 4 As shown, the size-adjustable clamp 3 includes a cylindrical seat 31, on which are provided three slide grooves 32 distributed in a circular array, in which are slidably provided clamping blocks 33, on both sides of the slide grooves 32 are provided externally threaded guide shafts 34 fixedly connected to the outer wall of the cylindrical seat 31, on which are slidably sleeved sliding sheets 35, which are fixedly connected to the outer side surfaces of the clamping blocks 33, and through the above-mentioned structural form, the cap of the lip glaze brush is clamped and fixed by the three clamping blocks 33, so that it can move synchronously with the rotation of the rotating table 2, and because the clamping blocks 33 can change the clamping size by sliding in the slide grooves 32, it can meet the fixing work of lip glaze brushes with caps of different sizes within a certain range.

[0039] In particular, the upper part and both sides of the inner side of the clamping block 33 are processed to form a groove 331, and the slope of the groove 331 is a smooth curved surface. This structural form can make the insertion process when installing the lip glaze brush smoother. The groove 331 applies a thrust to the clamping block 33 to make it slide inward, so that the lip glaze brush can be inserted smoothly.

[0040] In addition, an anti-drop cap 341 is fixedly provided at the outer end of the externally threaded guide shaft 34, a threaded adjustment ring 36 is sleeved on the externally threaded guide shaft 34, and a reset spring 37 sleeved on the outside of the externally threaded guide shaft 34 is provided between the adjustment ring 36 and the sliding sheet 35. Through the above-mentioned structural form, the reset spring 37 can push the clamping block 33 to apply a clamping force to the lip glaze brush installed therein, so that it is clamped and fixed, and when the adjusting ring 36 is turned, it can move back and forth along the externally threaded guide shaft 34 under the action of thread engagement, and the clamping force provided by the clamping block 33 can be changed by changing the compression degree of the reset spring 37.

[0041] like Figure 5 As shown, the rotating table 2 includes a bottom cylinder 21, and two connecting bearings 22 arranged up and down are fixedly installed on the inner wall of the top of the bottom cylinder 21. A rotating cylinder 23 located inside the bottom cylinder 21 is arranged on the top, and the outer wall of the rotating cylinder 23 is fixedly connected to the inner ring of the connecting bearing 22. A table plate 24 is fixedly arranged on the top of the rotating cylinder 23, and a driving motor 25 is fixedly installed in the bottom cylinder 21. The output shaft end of the driving motor 25 is drivingly connected to the center of the lower end surface of the table plate 24. Through the above-mentioned structural form, the driving motor 25 can drive the table plate 24 to rotate, thereby driving the inserted brush rod to rotate and transport it to the marking position. In addition, the two connecting bearings 22 can share most of the vertical load and provide stable support for the table plate 24.

[0042] The use principle and use process of the utility model are as follows: after the lip glaze brush is installed on the size-adjustable fixture 3 with the brush head facing upward, the driving motor 25 in the rotating table 2 drives the table plate 24 to rotate and transport the brush rod to the dotting position. During this process, the brush rod will pass through the constraint groove and will be straightened and corrected by the inner constraint semi-ring 41 and the outer constraint semi-ring 42; when the brush rod reaches the designated dotting position, the electric telescopic rod 45 pushes the tapered straightening fork 44 forward to straighten and correct the brush rod in a direction perpendicular to the previous straightening direction, ensuring that the brush rod to be dotted has no obvious deviation, thereby ensuring the dotting effect.

[0043] In addition, the size-adjustable clamp 3 can fix and install lip gloss brushes with different cap sizes. It clamps and fixes the cap of the lip gloss brush through three clamping blocks 33, so that it can move synchronously with the rotation of the rotating table 2. Since the clamping block 33 can change the clamping size by sliding in the slide groove 32, it can meet the needs of fixing lip gloss brushes with caps of different sizes within a certain range.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
