[0134] Figure 1 The image shown is a perspective view of the folding and interlocking waistband device of this utility model. In the following description, it will be referred to as... Figure 1 The attached diagram serves as a reference for orientation. The length direction of the lower platform 23 is defined as the left-right direction, with the upper left folding unit 11 located on the left and the upper right folding unit 12 located on the right. The width direction of the lower platform 23 is defined as the front-back direction, with the lower platform 23 located in front of the lower left folding unit 21. The thickness direction of the lower platform 23 is defined as the up-down direction, with the upper folding mechanism 1 located above the lower folding mechanism 2.

[0135] This utility model provides a folding and interlocking device for trouser waistbands, which is used to fold the upper and lower fabric pieces of the waistband. For example... Figure 1 As shown, the device includes an upper folding mechanism 1 and a lower folding mechanism 2.

[0136] like Figure 18 As 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.

[0137] like Figure 1-3 As shown, the upper folding mechanism 1 includes an upper folding fixing plate 32, a first lifting drive source 31 mounted on the upper folding fixing plate 32, and an upper folding lifting plate 33 that is connected to the first lifting drive source 31 in a transmission manner. An upper folding unit is provided on the upper folding lifting plate 33, and the first lifting drive source 31 is used to drive the upper folding unit to move up and down as a whole.

[0138] like Figure 3-11As shown, the upper folding unit includes a second lifting drive source 111 and a floating mounting plate 114 that moves up and down under the drive of the second lifting drive source 111. An upper edge-fastening push plate assembly 41, an upper straight edge push plate assembly 42, an upper cavity assembly 43, an upper fixed push plate assembly 44, an upper cavity baffle assembly 45, and an upper edge-expanding assembly 46 are mounted on the floating mounting plate 114. The second lifting drive source 111 can drive the upper edge-fastening push plate assembly 41, the upper straight edge push plate assembly 42, the upper cavity assembly 43, the upper fixed push plate assembly 44, the upper cavity baffle assembly 45, and the upper edge-expanding assembly 46 to move up and down synchronously.

[0139] Preferably, the upper folding unit further includes a lifting floating plate 112 connected to the second lifting drive source 111, and a third lifting drive source 113 installed at the bottom of the floating mounting plate 114. The third lifting drive source 113 is connected to the lifting floating plate 112. When adjusting the height of the floating mounting plate 114, the second lifting drive source 111 drives the lifting floating plate 112 to move up and down, causing the third lifting drive source 113 and the floating mounting plate 114 to move up and down synchronously, thereby achieving a large-scale adjustment of the height of each component on the floating mounting plate 114. Then, the second lifting drive source 111 stops working, and the third lifting drive source 113 starts working. Since the height of the lifting floating plate 112 is fixed, the third lifting drive source 113 drives the floating mounting plate 114 to move up and down, thereby achieving a small-scale precise adjustment of the height of each component on the floating mounting plate 114.

[0140] The first lifting drive source 31 and the second lifting drive source 111 are both cylinders. The piston rod of the cylinder of the first lifting drive source 31 is connected to the upper folding lifting plate 33, and the piston rod of the cylinder of the second lifting drive source 111 is connected to the lifting floating plate 112. The third lifting drive source 113 is a lead screw motor, the motor part of which is installed at the bottom of the floating mounting plate 114. Its lead screw extends in the vertical direction and passes through the lifting floating plate 112, and its lead screw nut is connected to the lifting floating plate 112. Those skilled in the art can also replace the specific type of linear displacement equipment selected for the first lifting drive source 31, the second lifting drive source 111, and the third lifting drive source 113 as needed.

[0141] like Figure 7 and Figure 18 As shown, the upper cavity assembly 43 includes an upper cavity plate 433 installed below the floating mounting plate 114. The bottom of the upper cavity plate 433 is provided with an upper cavity for accommodating the upper fabric piece 6. The upper fabric piece 6 is detachably installed in the upper cavity.

[0142] Specifically, the upper cavity assembly 43 has the following two embodiments to achieve detachable installation between the upper fabric piece 6 and the upper cavity:

[0143] like Figure 7As shown, in Embodiment 1 of the upper cavity assembly 43, the upper cavity is connected to a negative pressure mechanism for negative pressure adsorption and fixation of the upper fabric sheet 6. The negative pressure mechanism is specifically a vacuum machine.

[0144] like Figure 8 As shown, in embodiment 2, the upper cavity assembly 43 includes a needle-punching drive source 437 connected to the floating mounting plate 114 via a needle-punching frame 438, and a needle-punching block 432 that moves up and down under the drive of the needle-punching drive source 437. The needle-punching block 432 is located above the upper cavity plate 433, and its lower end is provided with several sets of fixing needles 4321. Each set of fixing needles 4321 passes through the upper cavity plate 433. When the needle-punching drive source 437 drives the needle-punching block 432 to move down, the fixing needles 4321 enter the upper cavity and needle-punch the upper fabric piece 6 to fix it, thus firmly installing the upper fabric piece 6 in the upper cavity.

[0145] In embodiment two, the top of the upper cavity plate 433 is provided with two needle-punching guide blocks 434, each needle-punching guide block 434 having an inclined surface, and the inclined surfaces of the two needle-punching guide blocks 434 are arranged opposite each other. A needle-punching block 432 is also slidably disposed on each inclined surface. The fixing needle 4321 at the lower end of each needle-punching block 432 has an included angle (preferably 40°) with the lower surface of the upper cavity plate 433 (i.e., the upper surface of the upper cavity), meaning that each set of fixing needles 4321 is inclined to pierce the upper fabric piece 6, effectively preventing the upper fabric piece 6 from falling off the fixing needle 4321. A needle-punching pressure block 435 is connected to the needle-punching drive source 437, and the needle-punching pressure block 435 abuts against the two needle-punching blocks 432 respectively. Simultaneously, a tension spring 436 is also provided between the needle-punching frame 438 and the needle-punching pressure block 435. When the needle-punching drive source 437 is working, it can drive the needle-punching pressure block 435 to move downward against the elastic force of the tension spring 436. The needle-punching block 432 slides down the inclined plane under the force of the needle-punching pressure block 435, so that the fixing needle 4321 enters the upper cavity and completes the needle-punching and fixing of the upper fabric piece 6. The needle-punching drive source 437 is preferably a cylinder, and its cylinder piston rod is connected to the needle-punching pressure block 435.

[0146] Furthermore, the upper cavity assembly 43 also includes a lifting drive source 431 connected to the floating mounting plate 114. The upper cavity plate 433 has a through hole 4332 communicating with the upper cavity. The output end of the lifting drive source 431 can pass through the through hole 4332 to press down the upper fabric piece 6, causing the upper fabric piece 6 to press against the lower fabric piece 7. The lifting drive source 431 is preferably a cylinder, and its output end is a cylinder piston rod.

[0147] like Figure 4-5 , Figure 7-8 and Figure 18As shown, the upper edge pusher plate assembly 41 is located on the rear side of the upper cavity assembly 43. It includes an upper edge fixing plate 418 connected to the floating mounting plate 114. An upper edge pusher plate drive source 413 and an upper edge lifting drive source 417 are fixed on the upper edge fixing plate 418. The upper edge pusher plate drive source 413 is connected to the upper edge pusher plate 412. The upper edge pusher plate drive source 413 can drive the upper edge pusher plate 412 to translate upwards towards the cavity (i.e., translate in the front-to-back direction), so that the upper fabric piece folds inwards at the non-fastening side 611 of the fastening edge. An upper edge lifting bracket 415 is connected to the upper edge lifting drive source 417. An upper edge guide drive source 416, an upper edge tongue plate drive source 414, and an upper edge tongue plate 411 are sequentially connected to the upper edge lifting bracket 415. The upper edge lifting drive source 417 can drive the upper edge tongue plate 411 to rise and fall, while the upper edge guide drive source 416 and the upper edge tongue plate drive source 414 can drive the upper edge tongue plate 411 to move upward into the cavity, causing the upper fabric piece to fold inward at the edge-to-edge 612. Preferably, the upper edge lifting drive source 417 is a lead screw motor, the motor part of which is fixedly connected to the upper edge fixing plate 418, the lead screw of which extends in the vertical direction, and the lead screw nut of which is connected to the upper edge lifting bracket 415. The upper edge push plate drive source 413, the upper edge guide drive source 416, and the upper edge tongue plate drive source 414 are all cylinders. The cylinder piston rod of the upper edge push plate drive source 413 is connected to the upper edge push plate 412; the cylinder piston rod of the upper edge guide drive source 416 is connected to the upper edge tongue plate drive source 414; and the cylinder piston rod of the upper edge tongue plate drive source 414 is connected to the upper edge tongue plate 411.

[0148] like Figure 4 , Figure 6-9 and Figure 18 As shown, the upper straight-edge pusher assembly 42 and the upper fixed pusher assembly 44 are respectively disposed on the left and right sides of the upper cavity assembly 43. The upper straight-edge pusher assembly 42 includes an upper straight-edge pusher drive source 422 connected to the floating mounting plate 114 via an upper straight-edge fixed plate 421, and the upper straight-edge pusher drive source 422 is connected to the upper straight-edge pusher 424 via an upper straight-edge connecting plate 423. The upper fixed pusher assembly 44 includes an upper fixed pusher drive source 442 connected to the floating mounting plate 114 via an upper fixed pusher bracket 441, and the upper fixed pusher drive source 442 is connected to the upper fixed pusher 443 via an upper fixed connecting plate 444. The upper straight-edge push plate drive source 422 and the upper fixed push plate drive source 442 can respectively drive the upper straight-edge push plate 424 and the upper fixed push plate 443 to translate upwards towards the cavity (i.e., translate in the left-right direction), causing the two upper fabric pieces' non-interlocking edges 62 to fold inwards (here and in the following text, "folding inwards" refers to folding between the upper fabric piece 6 and the lower fabric piece 7). Preferably, both the upper straight-edge push plate drive source 422 and the upper fixed push plate drive source 442 are cylinders, and the piston rods of both cylinders are connected to the upper straight-edge connecting plate 423 and the upper fixed connecting plate 444, respectively.

[0149] like Figure 4 , Figure 7-8 , Figure 10 and Figure 18 As shown, the upper cavity baffle assembly 45 includes an upper baffle block drive source 451 connected to the floating mounting plate 114 via an upper baffle block bracket 453. The upper baffle block drive source 451 is connected to the upper baffle block 452 and is used to drive the upper baffle block 452 to move up and down. A first slot 4331 is also opened on the rear side of the upper cavity plate 433. The upper baffle block 452 can move downward under the drive of the upper baffle block drive source 451 and pass through the first slot 4331 to enter the upper cavity, causing the upper fabric piece to fold downward against the fastening edge 61. The upper baffle block drive source 451 is preferably a cylinder, and its cylinder piston rod is connected to the upper baffle block 452.

[0150] like Figure 4 , Figure 11 and Figure 18 As shown, the upper edge widening assembly 46 is disposed near the upper edge push plate assembly 41 (close to the side where the upper edge tongue plate 411 is located), and is used to shape the shape of the seam formed by the fastening side 612 of the folded upper fabric piece. The upper edge widening assembly 46 includes an upper edge widening rod 464, a first drive source 463 for driving the upper edge widening rod 464 closer to or away from the upper cavity assembly 43 (i.e., translating in the left-right direction), and a second drive source 465 for driving the upper edge widening rod 464 to translate in the extension direction of the seam formed by the fastening side 612 of the folded upper fabric piece (i.e., translating in the front-back direction).

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 and right direction), so that the lower fabric piece folds inwards towards the button edge 72.

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.

[0159] Combination Figure 1-19 As can be seen, the working process of the folding and interlocking device for the waistband of this utility model is as follows:

[0160] Initial state: The cylinder piston rods of the first lifting drive source 31 and the second lifting drive source 111 are both in the extended state. The third lifting drive source 113 makes the floating mounting plate 114 at the preset loading height. At this time, the distance between the upper cavity and the lower cavity is the preset distance, which is specifically 30mm.

[0161] 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 cylinder piston rod of the upper fabric block drive source 451 extends, driving the upper fabric block 452 to move downward. The upper fabric block 452 passes through the upper cavity, causing the upper fabric piece to bend downward against the fastening edge 61.

[0162] The specific process of the upper cavity assembly 43 removing the upper fabric piece 6 is as follows:

[0163] When the upper cavity assembly 43 adopts the structure of Embodiment 1, the negative pressure mechanism works, and the upper fabric sheet 6 is adsorbed and fixed in the upper cavity due to the negative pressure.

[0164] When the upper cavity assembly 43 adopts the structure of Embodiment 2, the needle driving source 437 drives the needle block 432 to move downward, and the fixing needle 4321 passes through the upper cavity plate 433, enters the upper cavity and pierces the upper cloth piece 6, thus completing the fixing of the upper cloth piece 6.

[0165] 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 lower side lifting drive source 524 and the lower side tongue plate drive source 521 both extend, and then the cylinder piston rod of the lower side lifting drive source 524 retracts, driving the lower side tongue plate 526 to press onto the lower fabric piece 7.

[0166] Folding: The folding action of the upper folding unit is as follows: The piston rod of the cylinder of the upper straight edge push plate drive source 422 extends, and the upper straight edge push plate 424 enters the upper cavity; the piston rod of the cylinder of the upper fixed push plate drive source 442 retracts, and the upper fixed push plate 443 enters the upper cavity, folding the two non-clasp edges 62 of the upper fabric pieces inward into the upper cavity. The piston rod of the cylinder of the upper snap-edge push plate drive source 413 extends, driving the upper snap-edge push plate 412 to move towards the upper cavity, folding the non-clasp side 611 of the snap-edge edge of the upper fabric piece inward into the upper cavity. The upper snap-edge lifting drive source 417 drives its screw to rotate, causing the upper snap-edge lifting bracket 415 to move to the set pre-folding height, and then the piston rod of the cylinder of the upper snap-edge tongue plate drive source 414 extends, driving the upper snap-edge tongue plate 411 to move towards the upper cavity, pre-folding the snap-edge side 612 of the snap-edge edge of the upper fabric piece inward into the upper cavity. The piston rods of the cylinders of the first drive source 463 and the second drive source 465 of the upper edge expanding rod both extend, driving the upper edge expanding rod 464 into the gap formed by the fastening side 612 of the folded upper fabric piece, shaping the gap to a predetermined state. The piston rods of the cylinders of the first drive source 463 and the second drive source 465 of the upper edge expanding rod both retract, and the upper edge expanding rod 464 resets.

[0167] 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 lower side tongue plate drive source 521 retracts, driving the lower 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 rod of the cylinder of the lower side lifting drive source 524 extends, driving the lower side tongue plate drive source 521 and the lower side push plate drive source 522 to move upward; the piston rods of the cylinders of the lower side tongue plate drive source 521 and the lower side push plate drive source 522 both extend, driving the lower side tongue plate 526 and the lower side push plate 525 to move horizontally towards the lower cavity respectively, and the lower side tongue plate 526 and the lower side push plate 525 enter the lower cavity, folding the non-buttoned edge 71 of the lower fabric piece inward into the lower cavity. The folding state of the upper fabric piece 6 and the lower fabric piece 7 is as follows. Figure 18 As shown.

[0168] The folding actions of the aforementioned upper and lower folding units can be performed simultaneously.

[0169] Pre-fastening: The third lifting drive source 113 drives its lead screw to rotate, causing the floating mounting plate 114 to move down to the pre-fastening height. The lower fastening edge lifting drive source 533 drives its lead 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 19 As shown.

[0170] Interlocking: The third lifting drive source 113 drives its lead screw to rotate, causing the floating mounting plate 114 to move upward to the joining height. During this process, steps 1) and 2) are performed simultaneously:

[0171] 1) The upper edge lifting drive source 417 drives its screw to rotate, so that the upper edge tongue plate 411 moves to the same height as the upper edge push plate 412. At the same time, the cylinder piston rod of the upper edge guide drive source 416 extends, driving the upper edge tongue plate 411 to fully enter the upper cavity.

[0172] 2) The lower edge lifting drive source 533 drives its lead screw to rotate, so that the lower edge push plate 535 moves to the same height as the lower straight edge push plate 541. At the same time, the cylinder piston rod of the lower edge guide drive source 534 extends, driving the lower edge push plate 535 to fully enter the lower cavity.

[0173] At this point, the folding and interlocking of the waistband is complete, as follows: Figure 20 As shown.

[0174] Furthermore, to simultaneously complete the folding and interlocking of the left and right waistbands and improve work efficiency, such as... Figure 1 As shown, the upper folding mechanism 1 of this utility model includes two upper folding units, namely, the upper left folding unit 11 and the upper right folding unit 12; the lower folding mechanism 2 includes two lower folding units, namely, the lower left folding unit 21 and the lower right folding unit 22. The upper left folding unit 11 and the lower left folding unit 21 are arranged vertically correspondingly, and the upper right folding unit 12 and the lower right folding unit 22 are also arranged vertically correspondingly. The upper left folding unit 11 and the upper right folding unit 12 have the same structure and operation process, and are arranged symmetrically from left to right; the lower left folding unit 21 and the lower right folding unit 22 have the same structure and operation process, and are arranged symmetrically from left to right.

[0175] 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.
