Description

Technical Field

[0001] The utility model relates to an inner ring feeding device, in particular to an inner ring feeding device of hair extension buckle assembling equipment. Background Art

[0002] Hair extensions are well-known and popular products used to increase the length or volume of an individual's hair while blending into or becoming integral with the wearer's hair. Hair extensions allow the wearer to modify the appearance of their hair by typically adding multiple extensions of a selected length or lengths and color or colors to achieve a desired look.

[0003] like Figure 3 The figure shows a popular nano hair extension buckle. It consists of an outer ring 8 and an inner ring 9 positioned within the outer ring 8. The outer ring is typically made of metal, while the inner ring 9 is typically made of silicone. Silicone itself has a certain degree of elasticity. Once inserted into the outer ring 8, the inner ring 9 is locked to the outer ring through its own elasticity. To attach the hair, a crochet hook is used to pass the hair through the inner ring 9, which then clamps the hair in place.

[0004] At present, although there are automated assembly equipment for the assembly of the inner ring 9 and the outer ring 8, both the outer ring 8 and the inner ring 9 are loaded through a vibration plate, and the inner ring 9 is made of silicone. Under high temperature conditions, it is easy to stick in the vibration plate and difficult to separate, resulting in poor loading conditions and low work efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an inner ring feeding device for hair extension buckle assembly equipment.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a raw material storage roll, a guide tube, a driving wheel group, a cutting piece, a cutting drive mechanism, an inner ring turntable and a main motor, the main motor drives the inner ring turntable to rotate and the inner ring turntable is provided with an inner ring hole for placing the inner ring, the guide tube is arranged opposite to the inner ring hole, the raw material storage roll is arranged opposite to the guide tube and the silicone tube is provided to the guide tube, the silicone tube passes through the guide tube, the driving wheel group is arranged on both sides of the guide tube and drives the movement of the silicone tube in the guide tube, the cutting piece is arranged between the guide tube and the inner ring turntable, the cutting drive mechanism drives the cutting piece to move, the cutting piece has a cutting state located on the inner ring hole and a non-cutting state located outside the inner ring hole, the outer ring loading device corresponding to the above-mentioned solution can still adopt the vibration plate loading, and then perform corresponding assembly, and the cutting piece can be a blade.

[0007] By adopting the above technical solution, the silicone tube is led out from the raw material storage roll, positioned by the guide tube, and then pulled by the drive wheel group to the cutting position; the main motor drives the inner ring turntable to rotate so that the inner ring hole is aligned with the guide tube outlet, and the cutting drive mechanism pushes the cutting piece to move horizontally above the inner ring hole to complete the cutting, forming a single inner ring and falling into the inner ring hole for transportation; the continuous silicone tube is cut into rings on site, which completely avoids the problem of silicone inner ring sticking due to high temperature when loading on the traditional vibration plate; cutting and turntable transportation are synchronized to achieve precise positioning and efficient separation of the inner ring, thereby improving assembly stability and production efficiency.

[0008] The cam is secured to the drive mechanism and is secured to the cam by a spring that is secured on the cam face and is in a position to move relative to the inner ring hole.

[0009] By adopting the above technical solution, the main motor synchronously drives the pulling disk to rotate. When the arc-shaped transition section contacts the mating wheel, the sliding block overcomes the tension of the tension spring and moves away from the inner ring hole; when the outer circle of the pulling disk presses against the mating wheel, the sliding block maintains the retreat position; when the gap turns to the mating wheel, the tension spring is instantly released to drive the cutting piece to punch the silicone tube. A single motor is used to synchronously realize the turntable indexing and cutting timing control, and the mechanical linkage does not require additional sensors; the tension spring energy storage punching provides instantaneous shear force to ensure that the incision is smooth and there is no silicone residue; the three-state automatic switching improves the reliability of the action and reduces the complexity of the equipment.

[0010] The utility model is further configured as follows: the driving wheel group includes a driving wheel, an active motor and a driven wheel, matching grooves which are respectively adapted to the driving wheel and the driven wheel are provided on both sides of the guide tube, the driving wheel and the driven wheel are respectively provided on both sides of the guide tube and opposite to the matching grooves, the active motor drives the driving wheel to be opposite to each other and constitutes the driving wheel and the driven wheel to drive the silicone tube.

[0011] By adopting the above technical solution, the active motor drives the active wheel to rotate, and through the opposite clamping with the driven wheel at the matching groove of the guide tube, friction drive is formed on the silicone tube; the silicone tube is transported in the guide tube to avoid bending and deformation.

[0012] The utility model is further configured as follows: the driving wheel group also includes a fixed seat, a left moving block and a right moving block, the fixed seat is provided with a fixed track, the left moving block and the right moving block are slidably arranged on the fixed track, the driving wheel and the driving motor are arranged on the right moving block, the driven wheel is arranged on the left moving block, and a left screw and a right screw are respectively provided on both sides of the fixed seat, the left screw extends to abut against the left moving block, and the right screw extends to abut against the right moving block.

[0013] By adopting the above technical solution, rotating the left screw and the right screw can respectively push the left moving block and the right moving block to slide along the fixed track, thereby adjusting the clamping distance between the driving wheel and the driven wheel. Through mechanical fine-tuning, it can adapt to silicone tubes of different diameters and solve the problem of feeding failure caused by the tolerance of silicone raw materials. The modular design facilitates the rapid replacement of raw material specifications, enhances the versatility of the equipment and reduces downtime. BRIEF DESCRIPTION OF THE DRAWINGS

The guide tube 2 is arranged opposite to the inner ring hole 61. The raw material storage roll 1 is arranged opposite to the guide tube 2 and provides the silicone tube to the guide tube 2. The silicone tube passes through the guide tube 2. The driving wheel group 3 is arranged on both sides of the guide tube 2 and drives the movement of the silicone tube in the guide tube 2. The cutting piece 4 is arranged between the guide tube 2 and the inner ring turntable 6. The cutting drive mechanism 5 drives the cutting piece 4 to move. The cutting piece 4 has an inner ring hole 61 located on the inner ring hole 61. In the cutting state and the non-cutting state outside the inner ring hole 61, the outer ring loading device corresponding to the above scheme can still adopt the vibration disk loading, and then perform corresponding assembly. The cutting piece 4 can be a blade, and the silicone tube is led out from the raw material storage roll 1, positioned by the guide tube 2, and pulled and transported to the cutting position by the driving wheel group 3; the main motor 7 drives the inner ring turntable 6 to rotate so that the inner ring hole 61 is aligned with the outlet of the guide tube 2, and the cutting drive mechanism 5 pushes the cutting piece 4 to move horizontally above the inner ring hole 61 to complete the cutting, forming a single inner ring and falling into the inner ring hole 61 for transportation; the continuous silicone tube is cut into rings on site, which completely avoids the problem of material jamming caused by high-temperature adhesion of the silicone inner ring during traditional vibration disk loading; cutting and turntable transportation are synchronized to achieve precise positioning and efficient separation of the inner ring , improving assembly stability and production efficiency.
