[0070] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0071] In the description of this utility model, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0072] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0073] Figure 6 The image shown is a perspective view of the waistband folding device of this utility model. In the following description, it will be referred to as... Figure 6 The attached diagram serves as a reference for orientation. The length direction of the lower platform 3 is defined as the left-right direction, with the left second folding unit 11 located on the left and the right second folding unit 12 located on the right. The width direction of the lower platform 3 is defined as the front-back direction, with the lower platform 3 located in front of the left first folding unit 21. The thickness direction of the lower platform 3 is defined as the up-down direction, with the left second folding unit 11 located above the left first folding unit 21.

[0074] This utility model provides a fabric folding mechanism, which includes a first folding unit. For example... Figure 1 As shown, the first folding unit includes a cavity plate 51 and a side pusher assembly 52 disposed on the outside of the cavity plate 51. The cavity plate 51 has a cavity, within which a fabric piece is detachably installed. The cavity can be located at the top or bottom of the cavity plate 51 and is connected to a negative pressure mechanism for negative pressure adsorption and fixation of the fabric piece. Specifically, the negative pressure mechanism is a vacuum machine.

[0075] like Figure 1 and Figure 2As shown, the side pusher assembly 52 includes a side limiting drive source 527, a side tongue drive source 521, and a side pusher drive source 522. The side tongue drive source 521 is used to drive the side tongue 526 to move closer to or away from the cavity, and the side pusher drive source 522 is used to drive the side pusher 525 to move closer to or away from the cavity. The side limiting drive source 527 is disposed between the side tongue 526 and the cavity. It is used to limit the stroke of the side tongue 526 so that the side tongue 526 has three relative positions with respect to the cavity: exiting the cavity, partially entering the cavity, and fully entering the cavity, thereby helping to complete the process of folding the fabric into different lengths.

[0076] Those skilled in the art can, as needed, arrange the side tongue plate 526 and the side push plate 525 on the same side or different sides of the cavity, so that the folding length at different positions on the fabric is different. When the side tongue plate 526 and the side push plate 525 are arranged on the same side of the cavity, they are used to fold different sides of the same edge on the fabric; when the side tongue plate 526 and the side push plate 525 are arranged on different sides of the cavity, they are used to fold two edges on the fabric.

[0077] Specifically, the side push plate assembly 52 also includes a side lifting drive source 524 and a side push plate drive source mounting plate 523 that moves up and down under the drive of the side lifting drive source 524. The side tongue plate drive source 521 and the side push plate drive source 522 are both mounted on the side push plate drive source mounting plate 523 and move up and down synchronously under the drive of the side lifting drive source 524. The side limit drive source 527, the side lifting drive source 524, the side tongue drive source 521, and the side push plate drive source 522 are all cylinders. The cylinder piston rod of the side lifting drive source 524 is connected to the side push plate drive source mounting plate 523. The cylinder piston rod of the side tongue drive source 521 is connected to the side tongue connecting plate 5261. The side tongue 526 is located on the top of the side tongue connecting plate 5261. The cylinder piston rod of the side limit drive source 527 is used to limit the stroke of the side tongue connecting plate 5261 and will not interfere with the folding action of the side tongue 526. The cylinder piston rod of the side push plate drive source 522 is connected to the side push plate connecting plate. The side push plate 525 is located on the top of the side push plate connecting plate and is at the same installation height as the side tongue 526.

[0078] Furthermore, such as Figure 8As shown, in the upper fabric piece 6 of the waistband, the two long straight edges on the left and right sides of the upper fabric piece 6 are both non-button-upper edges 62, and the short straight edge on the back side of the upper fabric piece 6 is the button-upper edge 61. One side of the button-upper edge 61 is the non-button-upper side 611, and the other side is the button-upper side 612. In the lower fabric piece 7 of the waistband, the short straight edge on the back side of the lower fabric piece 7 is the non-button-upper edge 71; the long straight edge on one side of the left or right side of the lower fabric piece 7 is the button-upper edge 72. The button-upper edge 72 is located on the side of the lower fabric piece 7 closest to the button-upper side 612 of the upper fabric piece.

[0079] like Figure 1-5 and Figure 8 As shown, the above-mentioned fabric folding mechanism is a waistband folding mechanism, which includes a lower platform 3, and a first folding unit is installed on the lower platform 3. The cavity is a lower cavity opened at the top of the cavity plate 51, and the lower fabric piece 7 of the waistband is detachably installed inside it. The side tongue plate 526 and the side push plate 525 are both located on the rear side of the lower cavity, and both are arranged in the left-right direction. The first folding unit also includes a lower edge push plate assembly 53, a lower straight edge push plate assembly 54, and a lower cavity baffle assembly 55. The lower cavity baffle assembly 55 and the side push plate assembly 52 are used to fold the non-buttoned edges 71 of the lower fabric piece, and the lower edge push plate assembly 53 is used to fold the buttoned edges 72 of the lower fabric piece.

[0080] like Figure 1-4 As shown, the lower edge push plate assembly 53 and the lower straight edge push plate assembly 54 are respectively disposed on the left and right sides of the cavity plate 51.

[0081] like Figure 3As shown, the lower edge push plate assembly 53 includes a lower edge lifting drive source 533 connected to the lower platform 3 via a lower edge fixing bracket 536. The lower edge lifting drive source 533 is connected to the lower edge lifting bracket 532 and is used to drive the lower edge lifting bracket 532 to move up and down. A lower edge guide drive source 534, a lower edge push plate drive source 531, and a lower edge push plate 535 are sequentially connected to the lower edge lifting bracket 532. Both the lower edge guide drive source 534 and the lower edge push plate drive source 531 can drive the lower edge push plate 535 to translate downwards towards the cavity (i.e., translate in the left-right direction), causing the lower fabric piece to fold inwards towards the button edge 72. Preferably, the lower edge lifting drive source 533 is a lead screw motor, whose motor part is fixedly connected to the lower edge fixing bracket 536, whose lead screw extends in the up-down direction, and whose lead screw nut is connected to the lower edge lifting bracket 532. To guide the vertical movement of the lower edge lifting bracket 532, a lower edge slider 537 extending in the vertical direction is provided on the lower edge fixed bracket 536, and a lower edge guide rail that slides and engages with the lower edge slider 537 is provided on the lower edge lifting bracket 532. Preferably, both the lower edge guide drive source 534 and the lower edge push plate drive source 531 are cylinders. The piston rod of the cylinder of the lower edge guide drive source 534 is connected to the lower edge push plate drive source 531, and the piston rod of the cylinder of the lower edge push plate drive source 531 is connected to the lower edge push plate 535.

[0082] like Figure 4 As shown, the lower straight edge push plate assembly 54 includes a lower straight edge push plate drive source 545 connected to the lower platform 3 via a lower straight edge fixing bracket 544. The lower straight edge push plate drive source 545 is connected to the lower straight edge push plate 541 via a lower straight edge push plate connecting block 542, and is used to drive the lower straight edge push plate 541 to translate downwards into the lower cavity (i.e., translate in the left-right direction) to press the lower fabric piece 7 placed in the lower cavity. Preferably, the lower straight edge push plate drive source 545 is a cylinder, and its cylinder piston rod is connected to the lower straight edge push plate 541 via the lower straight edge push plate connecting block 542. To guide the translation of the lower straight edge push plate 541 and avoid skewing, the lower straight edge push plate assembly 54 also includes a fixedly installed lower straight edge guide rail 543, which extends in the left-right direction, and the lower straight edge push plate connecting block 542 is slidably engaged with the lower straight edge guide rail 543.

[0083] like Figure 1As shown, the lower cavity baffle assembly 55 includes a lower baffle block drive source 551 connected to the lower platform 3 via a lower baffle block bracket 553. The lower baffle block drive source 551 is connected to the lower baffle block 552 and is used to drive the lower baffle block 552 to move up and down. A slot 511 is also opened on the rear side of the cavity plate 51. The lower baffle block 552 can move upward under the drive of the lower baffle block drive source 551 and pass through the slot 511 to enter the lower cavity, causing the lower fabric piece to fold upward against the fastening edge 71. The lower baffle block drive source 551 is preferably a cylinder, and its cylinder piston rod is connected to the lower baffle block 552.

[0084] like Figure 6-8 As shown, the present invention also provides a waistband folding device, which includes the aforementioned fabric folding mechanism and a second folding unit, with the second folding unit disposed above the first folding unit.

[0085] The second folding unit includes a floating mounting plate that can move up and down. The floating mounting plate is equipped with an upper edge pusher assembly 41, an upper straight edge pusher assembly 42, an upper cavity assembly 43, an upper fixed pusher assembly 44, and an upper cavity baffle assembly. The upper cavity assembly 43 includes an upper cavity plate installed below the floating mounting plate. The bottom of the upper cavity plate is provided with an upper cavity. The upper cavity and the cavity are arranged vertically opposite each other. The upper fabric piece 6 of the waistband is detachably installed inside. The upper cavity baffle assembly and the upper edge pusher assembly 41 are used to fold the upper fabric piece with the edge 61 fastened together, while the upper straight edge pusher assembly 42 and the upper fixed pusher assembly 44 are used to fold the upper fabric piece with the edge 62 not fastened together.

[0086] Combination Figure 1-9 As can be seen, the working process of the waistband folding device of this utility model is as follows:

[0087] Initial state: The floating mounting plate 114 is at the preset loading height. At this time, the distance between the upper cavity and the lower cavity is the preset distance, which is 30mm.

[0088] Feeding: The lower fabric piece 7 is manually placed into the lower cavity, and the upper fabric piece 6 is fed into the upper cavity. The upper cavity assembly 43 removes the upper fabric piece 6. The upper cavity baffle assembly causes the upper fabric piece to bend downwards against the fastening edge 61.

[0089] When the negative pressure mechanism is activated, the lower fabric piece 7 is adsorbed and fixed in the lower cavity due to the negative pressure. The cylinder piston rods of the side lifting drive source 524 and the side tongue drive source 521 both extend, and then the cylinder piston rod of the side lifting drive source 524 retracts, driving the side tongue 526 to press against the lower fabric piece 7.

[0090] Folding: The folding action of the upper folding unit is as follows: the upper straight edge push plate assembly 42 and the upper fixed push plate assembly 44 fold the two upper fabric non-opposite edges 62 inward into the upper cavity. Then the upper snap edge push plate assembly 41 folds the upper fabric snap-on non-opposite side 611 and the upper fabric snap-on side 612 inward into the upper cavity.

[0091] The folding action of the lower folding unit is as follows: The piston rod of the cylinder of the lower straight edge push plate drive source 545 extends, driving the lower straight edge push plate 541 to move horizontally towards the lower cavity and press against the lower fabric piece 7. The piston rod of the cylinder of the side tongue plate drive source 521 retracts, driving the side tongue plate 526 to exit the lower cavity. The piston rod of the cylinder of the lower fabric block drive source 551 extends, driving the lower fabric block 552 to move upward and pass through the lower cavity plate 51, causing the non-fastening edge 71 of the lower fabric piece to bend upward. The piston rods of the cylinders of the side lifting drive source 524 and the side limiting drive source 527 both extend, driving the side tongue drive source 521 and the side push plate drive source 522 to move upward; the piston rods of the cylinders of the side tongue drive source 521 and the side push plate drive source 522 both extend, driving the side tongue 526 and the side push plate 525 to translate downward into the lower cavity respectively, with the side push plate 525 entering the lower cavity; at the same time, the piston rod of the cylinder of the side limiting drive source 527 restricts the stroke of the side tongue 526, causing the side tongue 526 to partially enter the lower cavity, folding the non-buttoned edge 71 of the lower fabric piece inward into the lower cavity. At this time, the folded state of the upper fabric piece 6 and the lower fabric piece 7 is as follows. Figure 8 As shown.

[0092] The folding actions of the aforementioned upper and lower folding units can be performed simultaneously.

[0093] Pre-fastening: The floating mounting plate moves down to the pre-fastening height. The lower fastening edge lifting drive source 533 drives its screw to rotate, causing the lower fastening edge push plate 535 to move to the pre-folding height. Then, the cylinder piston rod of the lower fastening edge push plate drive source 531 extends, driving the lower fastening edge push plate 535 to move downwards towards the cavity, inserting the lower fabric fastening edge 72 into the gap formed by the folded upper fabric fastening edge fastening side 612, so that the lower fabric fastening edge 72 and the upper fabric fastening edge fastening side 612 are pre-fastened, as shown. Figure 9 As shown.

[0094] Furthermore, to simultaneously complete the folding and interlocking of the left and right waistbands and improve work efficiency, such as... Figure 5-7As shown, the waistband folding device of this utility model includes two second folding units and two first folding units, namely, a left second folding unit 11, a right second folding unit 12, a left first folding unit 21, and a right first folding unit 22. The left second folding unit 11 and the left first folding unit 21 are arranged vertically correspondingly, and the right second folding unit 12 and the right first folding unit 22 are also arranged vertically correspondingly. The left second folding unit 11 and the right second folding unit 12 have the same structure and operation process, and are symmetrically arranged horizontally; the left first folding unit 21 and the right first folding unit 22 have the same structure and operation process, and are symmetrically arranged horizontally.

[0095] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
