Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a low carbon eco-friendly injection bobbin, in which a low-carbon eco-friendly injection bobbin has a structure in which the injection bobbin is eco-structured in low carbon and eco- And includes a spiral core layer 10, a straight line layer 20, a rounded portion 30 (30 '), and a key portion 40 for constituting an integral structure.

BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a schematic view showing a process of forming a low carbon eco-friendly injection bobbin according to the present invention.

The spiral bank layer 10 according to the present invention is formed by spirally winding a paper tape. The helical core layer 10 is composed of a plurality of layers, and the helical core layer 10 is successively formed by alternately winding the paper tapes in a forward direction and a backward direction so as to have a predetermined length, Thereby forming a straight-line layer 20.

At this time, the linearly wound paper layer 20 is formed by winding paper tape on the surface layer of the spiral bank layer 10 and has extended portions 22 protruding from the spiral bank layer 10 at both ends thereof. The semi-finished product bobbin formed by the spiral bank layer 10 is loaded onto the backing roller, and the paper tape is fed in the direction orthogonal to the longitudinal direction of the semi-finished product bobbin, ).

Here, the paper tape to be formed to form the linearly wound layer 20 is formed longer than the length of the spiral layer 10 in advance. As the paper tape becomes longer, both ends of the straight tube layer 20 protrude to both sides with respect to the spiral core layer 10 to form the extended portion 22. [ Meanwhile, the length of the extended portion 22 is determined according to the size and shape of the rounded portions 30 and 30 'described later.

The semi-finished product bobbin consisting of the spiral bank layer 10 is mass-produced by a continuous process. Then, a paper tape is wound on the surface layer of the spiral bank layer 10 to further form a straight bank layer 20, The helical core layer 10 is safely protected by the linear core layer 20 to prevent the deformation of the helical core layer 10 and the expansion and contraction of the helical core layer due to humidity So that defects such as unwinding and tangling of the yarn due to deformation of the bobbin can be prevented during storage of the bobbin wound with the yarn.

The rounding portions 30 and 30 'according to the present invention are formed by rotationally pressing and molding the extending portions 22 on both sides of the linearly polarizing layer 20 inward. As shown in FIG. 1 (c), the rounding portions 30 and 30 'are formed by pressing a rotary mold frame at both ends of the linearly polarizing layer 20, wherein a round groove is formed in the rotary mold frame, The rounding portions 30 and 30 'are formed while being rolled inward along the grooves. As the frictional force is reduced by the rounding portions 30 and 30 'at the ends of the branch pipe bobbins, damage to the end portions is prevented due to friction with the end portions during the unwinding of the wound yarn.

The key portion 40 according to the present invention is formed so as to engage with the key engagement portion 1a of the injector rotating spindle 1 by press-molding the inner circumferential surface of the one round portion 30. The key portion 40 is formed by pressing a rounded portion 30 formed while being inwardly curled inward at the end of the straight pipe layer 20 with the inner mold. The inner diameter of the rotary spindle 1 is set larger than the outer diameter of the key engagement portion 1a of the rotary spindle 1 so that the key 42 is protruded on the inner peripheral surface or the inner diameter of the key pipe 34 is larger than the outer diameter of the key engagement portion 1a of the rotary spindle 1 So that the key groove 44 is recessed in the inner peripheral surface.

At this time, the mold for forming the key part 40 is inserted into the inside of the pressing part or the round part 30 for forcibly inserting the mold inside the round part 30, and the mold is pressurized from the outside of the corresponding branch pipe by the external mold And a rounded portion is inserted between the inner and outer molds to be molded or rotated.

The rounded portion 30 in which the key portion 40 is formed has an arcuate connection portion 32 and a key pipe 34 spaced apart from the straight pipe layer 20 at the end of the connection portion 32. 2, the rounding portion 30 corresponding to the key portion 40 has a double structure in which a key tube 34 is formed in addition to the straight line layer 20 on the inner side to improve the durability, The engagement with the engaging portion 1a prevents damage during transmission of the rotational force, and prolongs the service life due to repeated use.

Further, the key portion 40 is formed in a state in which the molding heat is maintained immediately after the rounding portion 30 is formed. Immediately after the rounding part 30 is formed, the mold is heated and flexible due to the frictional force with the rotating mold die. Therefore, the molding of the key part 40 can be performed quickly and easily without additional energy.

At this time, a support ring 50 composed of a branch ring or a neck ring is provided in the helical core layer 10. As shown in FIG. 3, the support ring 50 is fixed to the inside of the spiral support tube layer 20 or fixed by an adhesive, and a ring hole penetrating the center is inserted into the rotary spindle 1 to prevent the flow during the rotation of the branch pipe bobbin. Function.

In addition, a slip prevention rib 24 is formed on the outer circumferential surface of the linearly wound layer 20 so that the yarn is positioned. As a result, since the yarn initially wound on the surface layer of the linearly wound layer 20 is prevented from flowing by interlocking with the anti-slip ribs 24, the yarn slips, tangles or loosens due to vibration and pressure in the process of winding the yarn or unwinding the yarn .
