Detailed Description

The present invention will be further described with reference to the following examples and drawings, but the embodiments of the present invention are not limited thereto.

Referring to fig. 1 to 9, the garment hemming and sewing auxiliary device of the present embodiment includes a folding guide block 3 and a support block 4; along the moving direction of the cloth, the folding guide block 3 is gradually twisted and extended to the lower left in an inclined posture to a horizontal posture; the supporting block 4 is arranged on one side of the folding guide block 3, a sliding groove 5 which is used for sliding cloth and has a sealed top is arranged between the supporting block 4 and the folding guide block 3, the rear end of the sliding groove 5 is obliquely arranged, and the front end of the sliding groove 5 is horizontally arranged; a cloth passing groove 8 is arranged between the folding guide block 3 and the table surface of the sewing machine, and the cloth passing groove 8 is communicated with the sliding groove 5.

Referring to fig. 1 to 3 and 5, the folding guide block 3 is disposed in an arc shape along the moving direction of the cloth, and the folding guide block 3 is twisted and extended along the arc bending direction. Through setting up curved folding guide block 3 for the cloth is at the removal in-process, under folding guide block 3's guide, combines the arc crooked, makes the cloth can laminate folding guide block 3 more, thereby makes the clothing end can twist reverse the bending from the gesture of slope gradually along folding guide block 3, finally truns into horizontal word strip, realizes the folding of cloth, so that carry out sewing processing.

Referring to fig. 1-3 and 5, along the moving direction of the cloth, the supporting block 4 is arranged in an arc shape and is arranged corresponding to the folding guide block 3; the sliding groove 5 between the folding guide block 3 and the supporting block 4 is also arranged in an arc shape. The supporting block 4 is arranged in an arc shape and is matched with the folding guide block 3, so that cloth at the tail end of the garment slides in the arc-shaped sliding groove 5 to advance, and the folding is automatically completed under the guidance of the folding guide block 3.

Referring to fig. 6 and 8, the inner side of the supporting block 4 is obliquely disposed. Specifically, the side of the support block 4, which forms the sliding groove 5 with the folding guide block 3, is obliquely arranged. Thus, one side of the sliding groove 5 is the torsion guide surface 13 of the folding guide block 3, and the other side is the inclined surface 12 of the support block 4; under the action of the inclined surface 12, the cloth in the sliding groove 5 is pressed down, so that the tail end of the clothes is further attached to the folding guide block 3, and the folding effect is realized.

Referring to fig. 2 to 9, along the moving direction of the cloth, the top of the end of the folding guide block 3 is open, and the end of the folding guide block 3 is twisted into a horizontal position and then extends forwards to form a horizontal extension section 9. Thus, a horizontal extension 9 with an opened top is formed at the end of the folding guide block 3, and the end of the garment after folding is guided by the horizontal extension 9 and kept moving forward in a folded posture, at this time, since the top is opened, it is convenient for a worker to observe and adjust the position of the fabric at any time so as to be engaged with a needle of a sewing machine, thereby completing the sewing process.

Referring to fig. 2 to 8, the end of the supporting block 4 is open at the top. Like this for whole auxiliary device's end all opens the setting, so that vacate enough space and let the workman observe the adjustment, be favorable to improving subsequent sewing machining precision.

Referring to fig. 2 to 5, the folding guide block 3 is provided at its distal end with a cloth pressing block 6, and the cloth pressing block 6 is lower than the top of the sliding groove 5. Therefore, the height of the sliding groove 5 is reduced through the arrangement of the cloth pressing block 6, the folded cloth is compressed and molded, the folding posture is further consolidated, and the sewing processing of the tail end of the garment in the folding posture is ensured. In the present embodiment, the cloth pressing piece 6 is disposed at the distal end open position of the folding guide piece 3.

Referring to fig. 2-6, the rear end of the cloth pressing block 6 is rotatably connected with the folding guide block 3 and the supporting block 4, the folding guide block 3 and the supporting block 4 are provided with elastic elements 7, and the elastic force of the elastic elements 7 always causes the cloth pressing block 6 to be pressed on the horizontal extension section 9. Because the thickness of the junction of the tail end of the garment is large, the elastic element 7 is arranged, so that when the junction of the tail end of the garment passes through, the cloth can smoothly pass through the upward rotation of the cloth pressing block 6, the self-adaptive function is realized, meanwhile, the folding cloth can adapt to the folding of the cloth with different thicknesses, and the adaptability is good.

Referring to fig. 2 to 8, a connecting assembly is arranged at the top of the folding guide block 3 and the supporting block 4, the connecting assembly comprises two oppositely arranged connecting lugs 10, and the rear end of the cloth pressing block 6 is rotatably connected with the two connecting lugs 10 through a rotating shaft. In this embodiment, the elastic element 7 is a torsion spring, and the torsion spring is disposed on the rotating shaft. Through the setting of coupling assembling, the connection of compress 6 of being convenient for to realize compress 6's elasticity and rotate the connection.

Referring to fig. 1-3, the sewing machine further comprises a plurality of movable rods 2, wherein the movable rods 2 are connected together end to end in a rotating manner, one end of each movable rod 2 is connected to a workbench 1 of the sewing machine in a rotating manner, and the other end of each movable rod 2 is connected to the supporting block 4 in a rotating manner. In this embodiment, a connecting block 11 is arranged on one side of the front end of the supporting block 4, and the connecting block 11 is rotatably connected with the movable rod 2; the movable bar 2 of the present embodiment is provided with two. Through the setting of movable rod 2, realize auxiliary device's nimble removal, put again all the time simultaneously on sewing machine's workstation 1 to workman angle of adjustment and position wantonly facilitates the use.

Referring to fig. 1 to 9, the working principle of the garment hem sewing auxiliary device of the present embodiment is:

when the edge folding and sewing are carried out on the tail end of the garment, the auxiliary device is moved to the rear of a needle of a sewing machine, then the tail end of the garment to be sewn firstly passes through the cloth passing groove 8, and the tail end of the garment is folded along the folding guide block 3, so that the starting sewing position of the tail end of the garment at the front end of the sliding groove 5 is already folded; then, begin to carry out the sewing to the start sewing position of clothing end, in the in-process of pushing away clothing cloth forward, clothing end is folding along folding guide block 3 automatic completion for the staff can continuously carry out the sewing operation, concentrate on the sewing position can, need not to make auxiliary operation or other actions to the folding of clothing end, simplifies the sewing processing step, effectively improves sewing convenience, sewing efficiency and precision.

The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
