[0015] Optionally, the second abutting plate is further provided with a communication gap parallel to the length direction of the second communication hole.

[0016] By adopting the above technical solution, by providing a communication gap in the second abutting plate, the frictional force between the surface layer member and the second abutting plate can be increased, which facilitates the staff to stitch and fix the surface layer member and the base fabric.

[0017] Optionally, a plurality of anti-slip grooves are provided on the side of the second abutting plate close to the ground.

[0018] By adopting the above technical solution, by providing anti-slip grooves on the second abutting plate, the frictional force between the second abutting plate and the surface layer member is increased to facilitate the staff to stitch and fix the surface layer member and the base fabric.

[0034] The following further describes the present application in detail with reference to Figures 1-6 the accompanying drawings.

[0035] An embodiment of the present application discloses an auxiliary tool for producing a luggage case. The auxiliary tool of the present application is used to assist a sewing machine 3 in producing a component of the luggage case.

[0036] Referring to Figure 1 , an auxiliary tool for producing a luggage case, the component of the luggage case includes a base fabric 1 arranged in an arc shape and a surface layer member 2, and the surface layer member 2 is stitched and fixed to the base fabric 1. In this embodiment, the base fabric 1 is a cylindrical fabric; the surface layer member 2 includes a leather part 21 and a PVC transparent film 22. An accommodation through hole for accommodating the PVC transparent film 22 is formed in the middle of the leather part 21. The outer periphery of the PVC transparent film 22 is stitched and fixed to the inner periphery of the leather part 21, and the outer periphery of the leather part 21 is stitched and fixed to the base fabric 1.

[0037] Referring to Figure 2 , the sewing machine 3 for producing a luggage case includes a needle 31 and a bobbin case 32. The bobbin case 32 is used to accommodate and protect the bobbin. In this implementation, the bobbin case 32 is a horizontal cylindrical shape. The sewing thread on the needle 31 and the sewing thread in the bobbin case 32 are intertwined into a lockstitch to complete the sewing work of the base fabric 1 and the surface layer member 2.

[0038] Referring to Figure 2 and Figure 3 , the auxiliary tool for producing a luggage case includes a moving platform 4, a connecting member 5 and a forming die 6. The forming die 6 is fixedly arranged on the moving platform 4, and the moving platform 4 drives the forming die 6 to move along the X-axis or Y-axis on a horizontal plane. The moving platform 4 operates in an electric manner, and the staff can control the movement of the driving end of the moving platform 4 through a foot pedal. The moving platform 4 can be composed of linear modules 42, cylinders 41 and other linear reciprocating driving members with perpendicular movement directions, and the moving platform 4 has many applications on existing electronic controlled pattern sewing machines. The present application does not limit the specific structure of the moving platform 4. In this embodiment, the moving platform 4 realizes the movement of the driving end along the X-axis or Y-axis on a horizontal plane through a cylinder 41 and a linear module 42 arranged perpendicular to each other.

[0039] Refer to Figure 2 and Figure 3 wherein, the driving end of the mobile platform 4 includes a first fixing plate 43 and a second fixing plate 44 which are oppositely arranged, and an elastic member (not shown) disposed between the first fixing plate 43 and the second fixing plate 44; the first fixing plate 43 is fixed on the mobile platform 4, and the second fixing plate 44 is fixedly connected with the connecting member 5; thereby realizing the relative sliding of the first fixing plate 43 and the second fixing plate 44 in the vertical direction. After the staff places the base cloth 1 and the surface layer member 2 between the needle 31 and the bobbin case 32, the staff presses the connecting member 5, so that the second fixing plate 44 drives the connecting member 5 and the forming die 6 to move towards the bobbin case 32, so that the forming die 6 and the bobbin case 32 press the base cloth 1 and the surface layer member 2. The elastic member disposed between the first fixing plate 43 and the second fixing plate 44 has the same working principle as the presser foot of the sewing machine 3, and the specific structure of the elastic member is not limited in this embodiment.

[0040] Refer to Figure 2 and Figure 3 The connecting member 5 is used to connect the driving end of the mobile platform 4 and the forming die 6, so as to facilitate the staff to replace forming dies 6 of different models. Refer to Figure 4 In this embodiment, the connecting member 5 includes a first connecting plate 51 and a second connecting plate 52 which are perpendicularly arranged, and the first connecting plate 51 and the second connecting plate 52 are integrally formed; the first connecting plate 51 is bolted to the driving end of the mobile platform 4, and the second connecting plate 52 is bolted to the connecting ear plate 62. And the number of bolt connections on the first connecting plate 51 is more than that on the second connecting plate 52; thereby improving the connection strength between the connecting member 5 and the mobile platform 4, and at the same time facilitating the staff to replace forming dies 6 of different models.

[0041] Refer to Figures 2 to 4 The forming die 6 is disposed between the needle 31 and the bobbin case 32 of the sewing machine 3. The forming die 6 includes a forming panel 61 and a connecting ear plate 62, the forming panel 61 and the connecting ear plate 62 are integrally formed, and the connecting ear plate 62 is fixedly connected with the driving end of the mobile platform 4. The forming panel 61 includes a first abutting plate 611 and a second abutting plate 612, the first abutting plate 611 and the second abutting plate 612 are integrally formed, a first communication hole 613 is provided between the first abutting plate 611 and the second abutting plate 612, and the leather part 21 of the surface layer member 2 is disposed in the first communication hole 613. The first abutting plate 611 is used to abut against the base cloth 1, and the second abutting plate 612 is used to abut against the surface layer member 2. In this embodiment, the first communication hole 613 is a groove-shaped communication hole, and the opening direction of the first communication hole 613 faces the mobile platform 4.

[0042] When the staff stitches the surface layer member 2 on the base cloth 1 arranged in an arc shape, the formed panel 61 arranged in an arc shape has a shaping effect on the base cloth 1. Specifically, the first abutting plate 611 has a limiting and guiding effect on the base cloth 1 on both sides of the surface layer member 2, so that the base cloth 1 always maintains an arc shape during the stitching process, thus facilitating the staff to stitch the base cloth 1 and the surface layer member 2 to improve the aesthetics of the finished luggage. The first communication hole 613 is a groove-shaped communication hole, so as to facilitate the staff to stitch and fix the outer periphery of the surface layer member 2 and the base cloth 1.

[0043] In addition, a long strip-shaped second communication hole 614 is formed in the middle area of the second abutting plate 612, and the second communication hole 614 is used for the needle 31 of the sewing machine 3 to pass through. A third communication hole 615 is also formed on one side of the second abutting plate 612 close to the connecting member 5 for the staff to stitch the end of the leather part 21. After the staff initially fixes the surface layer member 2 and the base cloth 1 through the first communication hole 613, the staff can further stitch and fix the base cloth 1 and the surface layer member 2 through the second communication hole 614 and the third communication hole 615 to improve the integrity of the stitching of the outer periphery of the surface layer member 2 and the base cloth 1.

[0044] At the same time, a communication gap 616 is also formed in the second abutting plate 612, and the communication gap 616 is parallel to the length direction of the second communication hole 614; thereby, the frictional force between the surface layer member 2 and the second abutting plate 612 can be increased, so as to facilitate the staff to stitch and fix the surface layer member 2 and the base cloth 1.

[0046] The difference between this Embodiment 2 and Embodiment 1 is that:

[0047] Referring to Figure 6 , a heightening pad 7 is bonded to the side of the first abutting plate 611 close to the ground, and the heightening pad 7 is used to abut against the base cloth 1; to increase the radian of the base cloth 1 during the stitching process and improve the stitching quality between the base cloth 1 and the surface layer member 2. At the same time, a plurality of anti-slip grooves 6121 are formed on the side of the second abutting plate 612 close to the ground to increase the frictional force between the second abutting plate 612 and the surface layer member 2, so as to facilitate the staff to stitch and fix the surface layer member 2 and the base cloth 1.

[0048] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
