Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description word energy
Enough implement according to this.
Should be appreciated that used herein such as " have ", " comprising " and " including " term do not allot one or many
Other element individual or the existence of a combination thereof or interpolation.
As shown in Figure 1, 2, the present invention provides a kind of optional automatic Wrapping apparatus of the many foldings of use in sewing machine, for carrying out to cloth
The optional bound edge operation of many foldings, it is characterised in that including:
Workbench 1；Fixing groove 2, it is arranged on the table, shapes from the upper surface concave downward of workbench, fixing groove
Length direction consistent with the direction of routing of sewing machine, and one end of fixing groove extend to distance needle 10-15cm
Place, the other end of fixing groove extends to the edge of workbench and runs through edge formation " u "-shaped opening；Divide coiling body 3, its
The lamellar body structural integrity coiling and molding the most trapezoidal by planar development, one end 4 of described point of coiling body is by the length of lamellar body structure
It is swirl shape that base is wound into cross section, and the other end 5 of described point of coiling body is wound into cross section by the short base of lamellar body structure
For semicircle arcuation, and the maximum gauge of one end of point coiling body less than or equal to the other end maximum gauge 1/2, described bundling
Sidewall around body does not contacts with each other；As it is shown on figure 3, coiling body, it is by two equal-sized first point of coiling body 3-1
Mutually it is spliced with two right angle waists 6 of second point of coiling body 3-2, and first point of coiling body and the one of second point of coiling body
Hold level with both hands neat；Forming a gap between first point of coiling body and second point of coiling body of two mutual splicings is cloth containing cavity；Institute
Stating that first point of coiling body of coiling body is embedded to be arranged in described fixing groove, the opening of described cloth containing cavity is towards fixing groove
Side, the second bundling is positioned at the surface of described fixing groove around body, and described cloth containing cavity and described workbench be in
One plane, and the length of the length of described coiling body and described fixing groove adapts；Holding part 7, it is by " U " of fixing groove

The vertically distance at least 1cm put foremost；And fixing post 12, its one end is fixed on workbench, and the other end is fixed
On the upper surface of pressing plate.
In such scheme, pressing plate is used for setting corresponding with changeover portion, to ensure to be positioned at the whirlpool of the edge cover strip above cloth
Shape structure to movable workbench spacing and pressing effect, smoothly completes bound edge operation with guarantee with cloth.
As shown in Figure 4, in a preferred version, also include: first guides wheels, and it is embedded is arranged on described changeover portion
Oblique sidewall on, described first guide wheels rotating direction consistent with the direction of routing of sewing machine, described first guide wheel
The upper extreme point of group is less than or equal to the upper surface of workbench.
In such scheme, first guides wheels to be used for mechanical guiding edge cover strip and cloth, and assists pressing swirling structure
Edge cover strip flanging process, it is ensured that more accurate flanging operation.
As shown in Figure 4, in a preferred version, described first guides wheels to include the unequal big wheel body of at least two diameter
13-1 and little wheel body 13-2, and the diameter proportion of described big wheel body and described little wheel body is 2-3:1.
As shown in Figure 4, in a preferred version, also include: second guides wheels, and it is embedded is arranged on described pressing plate,
The rotating direction of described second guiding wheels is consistent with the direction of routing of sewing machine, and described second guides the bottom point height of wheels
In or equal to the upper surface of workbench.
In such scheme, second guides wheels to be used for mechanical guiding edge cover strip and cloth, and assists pressing swirling structure
Edge cover strip flanging process, it is ensured that more accurate flanging operation.
As shown in Figure 4, in a preferred version, described second guides wheels to include the unequal big wheel body of at least two diameter
14-1 and little wheel body 14-2, and the diameter proportion of described big wheel body and described little wheel body is 2:1.
As in figure 2 it is shown, in a preferred version, the other end of described point of coiling body at least winds 540 degree of angles.
In such scheme, different winding degree can complete different flanging quantity, winds 540 degree of angles and can complete bag
Two folding bound edge operations of edge strip.
As shown in Figure 4, in a preferred version, described fixing post is scalable loop bar structure.
In such scheme, fixing post has telescopic action, can regulate the height of pressing plate at any time, to meet the cloth of different-thickness
Material bound edge operation.
