Therefore, the fabric corner turning auxiliary device can improve the efficiency of turning while ensuring the quality of turning the fabric.

[0031] Figure 1 Schematic diagram of the structure of a fabric corner turning auxiliary device disclosed in the present invention. Figure 1 As shown, the fabric corner turning auxiliary device includes a top corner positioning mechanism 100 and a corner turning clamping mechanism 200. The top corner positioning mechanism 100 includes a top corner piece 110 and a positioning piece 120. The top corner piece 110 has a pointed top end, and the top corner piece 110 is used to lift the corner of the fabric to be turned. The positioning piece 120 is used to mark the position of the pointed top end. The corner turning clamping mechanism 200 includes a corner clamping piece 210 and a driving assembly. The corner clamping piece 210 has an angle portion for clamping the angle of the fabric to be turned. The driving assembly can drive the angle portion to perform translational and rotational movements, and the pointed top end is arranged on the moving path of the angle portion.

[0032] It can be understood that the pointed top end is used to lift up the corner of the fabric to be turned up, and at this time, the pointed top end is arranged in a position corresponding to the corner of the fabric to be turned up. The angle clamping portion is used to clamp the corner of the fabric to be turned up on the pointed top end. Before the turning action is performed, the pointed top end is located on the inner side of the fabric to be turned up, and the angle clamping portion is used to clamp the outer side of the fabric to be turned up.

[0033] Reference Figure 1 As shown, in some examples of this embodiment, the driving assembly includes a rotary driving member 220, which is connected to the angle member 210, and is used to drive the angle member 210 to rotate, and the rotation axis of the rotary driving member 220 is located on the line connecting the tip top and the angle portion. The rotary driving member 220 is used to drive the tip top to rotate around the rotation axis, and its function is to drive the corner of the fabric to be turned to twist a certain angle. This operation can make the corner of the fabric to be turned over fully protrude as much as possible in the subsequent process of turning the fabric, thereby improving the problem that the corner is not sharp enough after turning the corner, and ensuring the quality of the corner turning.

[0034] In some examples of this embodiment, the rotary driving member 220 may be a rotary cylinder, and the angle member 210 may be directly connected to the rotary driving member 220 .

[0035] Reference Figure 1 As shown, in some examples of this embodiment, the driving assembly further includes a translation driving member 230, which is connected to the rotation driving member 220. The translation driving member 230 drives the angle member 210 to perform a translation action by driving the rotation driving member 220, and the translation direction of the translation driving member 230 is located on the line connecting the tip and the angle portion. The translation direction of the translation driving member 230 can be colinear with the rotation axis of the rotation driving member 220, so as to avoid affecting the rotation position of the angle portion during the translation process.

[0036] In some examples of this embodiment, the translation driving member 230 may be a telescopic cylinder. The telescopic action of the telescopic cylinder can drive the angle member 210 to translate.

[0037] In other embodiments, the translation drive member 230 is disposed between the angle member 210 and the rotation drive member 220, so that the angle member 210 can also perform rotation and translation movements. However, this will also cause the translation drive member 230 to rotate together and the rotation position of the angle portion is not easy to fix. Figure 1 The design can better avoid this problem.

[0038] Figure 2 for Figure 1 Schematic diagram of the enlarged structure of the A region in FIG. Figure 2 As shown, in some examples of this embodiment, the angle piece 210 includes a first angle plate 2101 and a second angle plate 2102, the first angle plate 2101 has a straight first angle surface, the second angle plate 2102 has a straight second angle surface, and the first angle surface and the second angle surface cooperate to form an angle portion. Figure 1 The design of the first angle surface and the second angle surface can increase the contact area between the angle portion and the fabric to be turned over, and after turning over the fabric to be turned over, the corner of the fabric can be separated from the angle portion by light pressure.

[0039] Further, refer to Figure 2 As shown, the end of the first angle plate 2101 and the end of the second angle plate 2102 are both pointed, which can further reduce the pressure required for the corner of the fabric to be separated from the angle portion.

[0040] Combination Figure 1~Figure 2As shown, in some examples of this embodiment, the angle piece 210 further includes an angle driving unit 2103, which is used to drive the first angle plate 2101 and the second angle plate 2102 to open and close, and the opening and closing stroke of the first angle plate 2101 and the second angle plate 2102 is adjustable. The angle driving unit 2103 can be directly connected to the first angle plate 2101 and the second angle plate 2102, and enables the first angle plate 2101 and the second angle plate 2102 to move closer or farther away, so that the opening and closing stroke of the first angle plate 2101 and the second angle plate 2102 is adjustable. The design of adjustable opening and closing stroke can make the angle piece 210 applicable to a variety of fabrics of different thicknesses, which is conducive to broadening the scope of application of the fabric turning angle auxiliary device.

[0041] Reference Figure 1 As shown, in some examples of this embodiment, the fabric corner turning auxiliary device further includes a bracket 300, and the angle piece 210 and the top corner piece 110 are both arranged on the bracket 300 and connected to the bracket 300. The angle piece 210 and the top corner piece 110 are arranged on the same bracket 300, which is conducive to ensuring that the relative position of the angle piece 210 and the top corner piece 110 is more fixed, and the two are convenient for alignment.

[0042] Further, refer to Figure 1 As shown, the positioning member 120 can also be connected to the bracket 300. For example, in this embodiment, the vertex positioning mechanism 100 further includes a positioning mounting plate 140, the positioning member 120 can be connected to the positioning mounting plate 140, the positioning mounting plate 140 is connected to the bracket 300, and the positioning member 120 is connected to the bracket 300 through the positioning mounting plate 140.

[0043] Further, refer to Figure 1 As shown, the driving assembly can be directly connected to the bracket 300, and the angle piece 210 is indirectly connected to the bracket 300 through the driving assembly.

[0044] Reference Figure 1 As shown, in some examples of this embodiment, the top corner piece 110 is detachably connected to the bracket 300. If the top corner piece 110 is detachable, the top corner piece 110 can be replaced when facing fabrics of different sizes. Therefore, this design can also make the top corner piece 110 suitable for fabrics of various sizes, which is conducive to broadening the scope of application of the fabric corner turning auxiliary device. For example, in this embodiment, the top corner positioning mechanism 100 also includes a top corner mounting handle 130. The top corner piece 110 is detachably arranged on the top corner mounting handle 130, and the top corner mounting handle 130 is connected to the bracket 300. The top corner piece 110 is detachably connected to the bracket 300 through the top corner mounting handle 130.

[0045] Reference Figure 1As shown, in some examples of this embodiment, the bracket 300 includes a base plate 310, a first support plate 320 and a second support plate 330, the two ends of the base plate 310 are respectively connected to the first support plate 320 and the second support plate 330, the first support plate 320 is also connected to the driving assembly, the second support plate 330 is also connected to the top corner piece 110 and the positioning piece 120, and the top corner piece 110 is detachably connected to the second support plate 330.

[0046] Reference Figure 1 As shown, in this embodiment, the bottom end of the first support plate 320 is connected to the bottom plate 310, and the top end of the first support plate 320 is connected to the translation driving member 230 in the driving assembly.

[0047] Reference Figure 1 As shown, in this embodiment, the bottom end of the second support plate 330 is connected to the bottom plate 310. The top corner piece 110 is detachably connected to the second support plate 330.

[0048] Reference Figure 1 As shown, in this embodiment, the positioning member 120 can also be connected to the second support plate 330, and the positioning member 120 can be arranged above the top corner member 110, so that the mark of the positioning member 120 can also be located above the top corner member 110, which is more convenient for the operator to observe the mark.

[0049] In some examples of this embodiment, the positioning member 120 includes a point light source, and the pointed top end is arranged on the irradiation path of the point light source. When the fabric to be turned is placed on the pointed top end, the point light source can grow a mark on the fabric to be turned by emitting light, which not only has a simple structure, but also can form a precisely positioned and eye-catching light spot, which is convenient for operators to perform alignment.

[0050] In some examples of this embodiment, the fabric corner turning auxiliary device further includes a protective container 400 . Figure 3 Shown based on Figure 1 The structure diagram of the fabric corner turning auxiliary device is shown as a protective container 400. Figure 3 As shown, the drive assembly can be arranged in the protection container 400, and the angle portion of the angle piece 210 and the pointed end of the top angle piece 110 are located outside the protection container 400. The protection container 400 can be used to protect the drive assembly located therein, and can also prevent the movement of the drive assembly from affecting the operation of the operator.

[0051] Furthermore, the present disclosure also provides a method for turning up the corners of a fabric, which includes steps S1 to S3, as follows.

[0052] Step S1 , using the fabric corner turning auxiliary device as in the above embodiment, the fabric to be turned corner is sleeved on the top corner piece 110 , and the corner of the fabric to be turned corner is aligned with the top end through the mark of the positioning piece 120 .

[0053] It can be understood that the fabric to be turned has relative inner and outer surfaces. When the fabric to be turned is sleeved on the top corner piece 110, the inner surface of the fabric to be turned contacts the top corner piece 110, and the pointed top of the top corner piece 110 can abut against the inner surface of the corner of the fabric to be turned.

[0054] In some examples of this embodiment, in step S1 , the fabric to be turned up can be sleeved on the top corner piece 110 by an operator.

[0055] In some examples of this embodiment, in step S1, when the fabric to be turned up is sleeved on the top corner piece 110, the fabric to be turned up covers the specific position of the pointed top. At this time, the positioning piece 120 can form a mark on the fabric to be turned up by means of a light and indicate the position of the pointed top, thereby facilitating the operator to accurately align the corner of the fabric to be turned up at the pointed top.

[0056] Step S2, using the angle clamping piece 210 to clamp the corner of the fabric to be turned, and making the angle clamping piece 210 drive the corner of the fabric to be turned to rotate.

[0057] It can be understood that the angle clamp 210 can clamp the outer surface of the angle of the fabric to be turned. By controlling the distance between the first angle plate 2101 and the second angle plate 2102 in the angle clamp 210, the angle clamp 210 can stably clamp the fabric to be turned.

[0058] When the angle of the fabric to be turned is driven to rotate, the rotation axis of the angle clamp 210 can be ensured to be located on the fabric to be turned, thereby avoiding displacement of the entire fabric to be turned, and only twisting the angle of the fabric to be turned by a certain angle. The rotation angle of the angle clamp 210 can be, for example, 180°, at which time the angle of the fabric to be turned is also twisted by 180°.

[0059] Step S3, controlling the opening edge of the fabric to be turned up to be turned up from the top corner piece 110 side toward the corner piece 210 side.

[0060] It can be understood that when the fabric to be turned corner is sleeved on the top corner piece 110, the opening edge of the fabric to be turned corner is located on the side of the top corner piece 110 away from the corner piece 210. At this time, the operator can turn the opening edge of the fabric to be turned corner toward the side of the corner piece 210, and continue to pull so that the opening edge of the fabric to be turned corner reaches the side of the corner piece 210 away from the top corner piece 110, that is, the flanging action. In this process, the original inner surface of the fabric to be turned corner is turned to the outside, and its outer surface is turned to the inside, that is, the turning process is completed.

[0061] After the flanging action is completed, the flanging process can be completed by releasing the fabric to be flanged held by the clamping member. Since the corner of the fabric to be flanged is twisted in advance in step S2, when the fabric to be flanged is released, the corner of the fabric to be flanged also pops out spontaneously, thereby ensuring that the corner of the fabric after flanging is prominent, thereby ensuring good flanging quality.

[0062] Through steps S1 to S3, the use of the fabric corner turning auxiliary device can be completed, and the corner turning process of the fabric can also be completed.
