[0200] like Figure 4 and Fig.24 As shown, the upper folding mechanism 1 includes an upper folding unit, which includes a floating mounting plate 114 that can move up and down, and the floating mounting plate 114 is equipped with an upper buckle edge 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 cloth stop assembly 45, an upper edge expansion assembly 46 and an upper clamp assembly 47. The upper cavity assembly 43 includes an upper cavity plate 433 installed below the floating mounting plate 114, and an upper cavity is provided at the bottom of the upper cavity plate 433 for accommodating an upper cloth piece 6, and the upper cloth piece 6 can be detachably installed in the upper cavity; the upper cavity cloth stop assembly 45 and the upper buckle edge push plate assembly 41 are used to fold the buckle edges 61 of the upper cloth piece, and the upper straight edge push plate assembly 42 and the upper fixed push plate assembly 44 are used to fold the two non-buckle edges 62 of the upper cloth piece; the upper edge expansion assembly 46 is used to shape the gap formed by the folded buckle edges 61 of the upper cloth piece; the upper clamp assembly 47 is used to place the trouser placket between the upper cloth piece 6 and the lower cloth piece 7.

[0201] like Figure 14-15 and Fig.24 As shown, the lower folding mechanism 2 includes a lower folding unit, which is arranged below the upper folding unit, and includes a lower cavity plate 51, a lower side push plate assembly 52, a lower buckle side push plate assembly 53, a lower straight side push plate assembly 54, and a lower cavity cloth stop assembly 55. A lower cavity for accommodating the lower cloth piece 7 is provided on the top of the lower cavity plate 51, and the lower cavity is arranged opposite to the upper cavity up and down. The area between the lower cavity plate 51 and the upper cavity plate 433 is a folding area, that is, the folding area includes the upper cavity, the lower cavity and the space between the two. The lower cavity is connected to the negative pressure mechanism, which is used to negatively adsorb and fix the lower cloth piece 7. The lower cavity cloth stop assembly 55 and the lower side push plate assembly 52 are used to fold the first non-buckled edge 71 of the lower cloth piece, the lower buckle side push plate assembly 53 is used to fold the buckled edge 72 of the lower cloth piece, and the lower straight side push plate assembly 54 is used to limit the lower cloth piece 7.

[0202] like Figure 19-20 As shown, the upper folding and feeding mechanism 8 includes an upper folding and feeding unit arranged below the upper cavity assembly 43, and the upper folding and feeding unit includes a movable upper folding and feeding plate 88, and a plurality of feeding needles 89 are provided on the top of the upper folding and feeding plate 88, which are used to feed the upper cloth piece 6 to the upper cavity.

The folding core unit includes a folding core 901, and the folding core 901 is provided with a plurality of air suction holes. The pressing unit is arranged above the folding core unit, and includes a movable pressing plate, which can be close to or away from the folding core 901. The folding core 901 can be moved into the lower cavity. After the upper folding unit and the lower folding unit complete the folding and interlocking of the upper cloth piece 6 and the lower cloth piece 7, the pressing plate can press the waistband of the pants against the folding core 901, and the folding core unit drives the waistband of the pants to move and exit the folding area.

[0204] The material taking mechanism is used to move the trouser waist on the folding core 901 to the feeding position of the pattern machine. It can specifically adopt a manipulator, which is a prior art and will not be described in detail here.

[0205] When the above-mentioned automatic folding and interlocking device for trouser waist works normally, starting from the initial state, the steps of loading, folding and interlocking, cavity material transfer and material removal are completed in sequence. The working process is as follows:

[0206] Initial state: The floating mounting plate 114 is at a preset loading height, and the distance between the upper cavity and the lower cavity is a preset distance. Each push plate assembly and the cloth blocking assembly in the upper folding unit and the lower folding unit are outside the folding area. The upper folding feed plate 88 is between the upper cavity and the lower cavity. The folding core 901 is in the lower cavity, and the press plate is at the farthest distance from the folding core 901.

[0207] Loading: manually place the lower cloth piece 7 on the folding core 901, place the upper cloth piece 6 on the upper folding feed plate 88, and let the feed needle 89 pierce the cloth piece 6. Place the trouser placket on the upper clamp assembly 47. The upper folding feed plate 88 moves to feed the upper cloth piece 6 into the upper cavity, and the upper cavity assembly 43 removes the upper cloth piece 6. Then the upper folding feed plate 88 exits the folding area. The upper cavity cloth blocking assembly 45 acts to bend the upper cloth piece downward against the buckle edge 61. The negative pressure mechanism works, and the lower cloth piece 7 is adsorbed and fixed in the lower cavity due to the negative pressure.

[0208] Folding and interlocking: 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 are operated to fold the two upper cloth pieces' non-buttoning edges 62 inwardly into the upper cavity. Then the upper clamp assembly 47 is operated to make the trouser placket close to the bottom of the upper cloth piece's non-buttoning edge 62 adjacent to the upper cloth piece's non-buttoning side 611; the upper button edge push plate assembly 41 is operated to fold the upper cloth piece's non-buttoning side 611 inwardly into the upper cavity, and to pre-fold the upper cloth piece's buttoning side 612 inwardly into the upper cavity; the upper edge expansion assembly 46 is operated to shape the shape of the gap formed by folding the upper cloth piece's buttoning side 612, so that the shape of the gap reaches a predetermined state; then the upper edge expansion assembly 46 is reset and exits the folding area. The folding action of the lower folding unit is as follows: the lower cavity cloth blocking assembly 55 is actuated to bend the first non-locking edge 71 of the lower cloth piece upward; the lower side edge pushing plate assembly 52 is actuated to fold the first non-locking edge 71 of the lower cloth piece inward into the lower cavity; the folding state of the upper cloth piece 6 and the lower cloth piece 7 is as follows: Fig.24 As shown. The folding actions of the upper folding unit and the lower folding unit can be performed simultaneously. Then the floating mounting plate 114 moves down to the pre-fastening height, and the lower fastening edge push plate assembly 53 is actuated to insert the lower fabric piece fastening edge 72 into the gap formed by the folded upper fabric piece fastening edge fastening side 612, so that the lower fabric piece fastening edge 72 and the upper fabric piece fastening edge fastening side 612 are pre-fastened, as shown in FIG. Fig.25 Then the floating mounting plate 114 moves up to the closing height. During the process of the floating mounting plate 114 moving up to the closing height, the following steps 1) and 2) are performed simultaneously: 1) the upper buckle edge push plate assembly 41 drives the upper buckle edge tongue plate 411 to completely enter the upper cavity; 2) the lower buckle edge push plate assembly 53 drives the lower buckle edge push plate 535 to completely enter the lower cavity. At this point, the folding and interlocking action of the trouser waist is completed, as shown in FIG. Fig.26 shown.

[0209] Cavity material transfer: Press the upper cloth piece 6 and the lower cloth piece 7 onto the folding core 901, with the trouser placket located between the non-fastening edge 62 of the upper cloth piece and the second non-fastening edge 73 of the lower cloth piece. Then the upper cavity assembly 43 releases the fixation of the upper cloth piece 6, and each push plate assembly and cloth stop assembly in the upper folding unit and the lower folding unit exit the folding area. The upper clamp assembly 47 is completely separated from the trouser placket. Then the pressing plate moves to press the trouser waist on the folding core 901. The folding core unit moves, and the folding core 901 and the pressing plate exit the folding area with the trouser waist and arrive at the material removal position. At this point, the cavity material transfer action is completed.

[0210] Material taking: the material taking mechanism moves to the material taking position, moves the trouser waist on the folding core 901 to the material loading position of the pattern machine, and the pattern machine receives the trouser waist and starts sewing.

[0211] As can be seen from the above, the automatic folding and interlocking device for trouser waistbands greatly reduces the requirements for workers' operating skills in the folding and interlocking process through automation, and can ensure the stability and uniformity of the sewing quality of trouser waistbands. The positions of the various mechanisms of the automatic folding and interlocking device for trouser waistbands will constantly change when completing different steps. When the device needs to be stopped and reset due to a fault, if the same reset method is used, it will cause interference and collision between the various mechanisms.

[0212] In order to ensure the smooth operation of the automatic folding and interlocking device for trouser waist, the present invention provides a method for resetting the automatic folding and interlocking device for trouser waist, such as Fig. 27 As shown, the following steps are included:

[0213] The automatic folding and interlocking device for the trouser waist stops working when the feeding action or the folding and interlocking step is completed, and step S1 is executed: first, the upper buckle edge push plate assembly 41 and the lower buckle edge push plate assembly 53 are controlled to exit the folding area respectively; then the upper straight edge push plate assembly 42, the upper fixed push plate assembly 44, the upper cavity cloth stop assembly 45, the lower side edge push plate assembly 52, the lower straight edge push plate assembly 54 and the lower cavity cloth stop assembly 55 are controlled to exit the folding area respectively, at which time the upper folding mechanism 1 and the lower folding mechanism 2 will not interfere with each other; then the floating mounting plate 114 is controlled to move upward, so that the upper folding mechanism 1 is away from the lower folding mechanism 1 and the upper folding feeding mechanism 8 at the same time, and the upper folding feeding plate 88 exits the folding area, at which time the upper folding mechanism 1, the lower folding mechanism 2, the upper folding feeding mechanism 8 and the pressing cavity moving mechanism 9 will not interfere with each other; finally, the pressing cavity moving mechanism 9 and the picking mechanism are controlled to reset, so that the folding core 901 exits the folding area, the pressing plate is at the farthest distance from the folding core 901, and the picking mechanism leaves the picking position.

[0214] The automatic folding and interlocking device of the waistband stops working when the cavity moving step is completed, and executes step S2: first control the folding core 901 to exit the folding area, and the pressing plate is away from the folding core 901. At this time, the pressing cavity moving mechanism 9 will not interfere with the upper folding mechanism 1, the lower folding mechanism 2 and the upper folding feeding mechanism 8; then control the floating mounting plate 114 to move upward, so that the upper folding mechanism 1 is away from the lower folding mechanism 1 and the upper folding feeding mechanism 8 at the same time, and there will be no interference between the three; finally, control the lower folding mechanism 2, the upper folding feeding mechanism 8 and the picking mechanism to reset, so that the lower side push plate assembly 52, the lower buckle side push plate assembly 53, the lower straight side push plate assembly 54 and the lower cavity cloth stop assembly 55 exit the folding area, the upper folding feeding plate 88 exits the folding area, and the picking mechanism leaves the picking position.

[0215] The automatic folding and interlocking device for the waistband stops working when the material picking step is completed, and step S3 is executed: first, the material picking mechanism is controlled to leave the material picking position; then the folding core 901 is controlled to exit the folding area, and the pressing plate is away from the folding core 901. At this time, the pressing cavity moving mechanism 9 will not interfere with the upper folding mechanism 1, the lower folding mechanism 2 and the upper folding feeding mechanism 8; then the floating mounting plate 114 is controlled to move upward, so that the upper folding mechanism 1 is away from the lower folding mechanism 1 and the upper folding feeding mechanism 8 at the same time, and there will be no interference between the three; finally, the lower folding mechanism 2 and the upper folding feeding mechanism 8 are controlled to reset, so that the lower side edge push plate assembly 52, the lower buckle edge push plate assembly 53, the lower straight edge push plate assembly 54 and the lower cavity cloth stop assembly 55 exit the folding area, and the upper folding feeding plate 88 exits the folding area.

[0216] From the above, it can be seen that the reset method provided by the present invention can reset each mechanism in different ways according to the different steps performed before the device stops working, which helps each mechanism to quickly return to its initial state and resume normal work, thereby improving production efficiency and reducing production costs caused by downtime due to faults.

[0217] The following describes the preferred structures of the upper folding mechanism 1, the lower folding mechanism 2, the upper folding and feeding mechanism 8, and the pressing cavity moving mechanism 9 in the automatic folding and interlocking device for trouser waistbands used in the present invention.

Since the height of the lifting floating plate 112 is fixed, the third lifting driving source 113 drives the floating mounting plate 114 to move up and down, thereby realizing a small-scale and precise adjustment of the height of each component on the floating mounting plate 114.

The avoidance driving assembly is used to drive the upper folding feeding driving source 82 and the upper folding feeding plate 88 to approach or move away from the upper cavity assembly 43 at the same time, so as to realize the avoidance action of the upper folding feeding unit 8. The upper folding feeding driving source 82 is used to drive the upper folding feeding plate 88 to enter or exit the upper cavity, so as to complete the feeding action to the upper cavity.

[0243] The avoidance drive assembly specifically includes an upper folding feed bottom plate 86, an upper folding feed connecting plate 84 slidably arranged on the upper folding feed bottom plate 86, a second upper folding avoidance drive source 85 for driving the upper folding feed connecting plate 84 to translate in the left-right direction, and a first upper folding avoidance drive source 83 arranged on the upper folding feed connecting plate 84. The first upper folding avoidance drive source 83 is connected to the upper folding feed drive source 82 through a connecting plate, and is used to drive the upper folding feed drive source 82 and the upper folding feed plate 88 to move up and down simultaneously. The second upper folding avoidance drive source 85 is used to drive the first upper folding avoidance drive source 83, the upper folding feed drive source 82 and the upper folding feed plate 88 to translate in the left-right direction simultaneously.

[0244] Preferably, the first upper folding avoidance drive source 83, the second upper folding avoidance drive source 85 and the upper folding feeding drive source 82 are all cylinders, wherein the lower end of the cylinder piston rod of the first upper folding avoidance drive source 83 is connected to the upper folding feeding connecting plate 84, the upper end of the cylinder piston rod of the upper folding feeding drive source 82 is connected to the upper folding feeding plate 88 through the upper folding feeding bracket 81, and the end of the cylinder piston rod of the second upper folding avoidance drive source 85 is connected to the upper folding feeding connecting plate 84.

[0245] Furthermore, in order to simultaneously complete the folding and interlocking work of the left and right trouser waists and improve work efficiency, Figure 2 As shown, the upper folding mechanism 1 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 folding feeding mechanism 8 includes two upper folding feeding units, namely, the upper left folding feeding unit 801 and the upper right folding feeding unit 802.

[0246] Among them, the upper left folding unit 11 and the lower left folding unit 21 are arranged correspondingly up and down, the upper right folding unit 12 and the lower right folding unit 22 are arranged correspondingly up and down, the upper left folding feeding unit 801 is used to feed materials to the upper left folding unit 11, and the upper right folding feeding unit 802 is used to feed materials to the upper right folding unit 12. The upper left folding unit 11 and the upper right folding unit 12 have the same structure and working process, and the two are arranged symmetrically on the left and right; the lower left folding unit 21 and the lower right folding unit 22 have the same structure and working process, and the two are arranged symmetrically on the left and right.

[0247] Press cavity moving mechanism

[0248] like Figure 1 , Figure 21-23 As shown, the pressing cavity moving mechanism 9 is arranged at the front side of the upper folding mechanism 1 and the lower folding mechanism 2, and includes a core translation driving source 94, a pressing moving bottom plate 93 that is transmission-connected to the core translation driving source 94, a folding core unit that is arranged on the pressing moving bottom plate 93, and a pressing unit that is transmission-connected to the pressing moving bottom plate 93. The core translation driving source 94 is used to drive the pressing moving bottom plate 93, the folding core unit and the pressing unit to translate synchronously along the front-back direction, approaching or moving away from the lower cavity plate 51. Each folding core unit includes a folding core 901 that is mounted on the pressing moving bottom plate 93 through a core support 902, and the folding core 901 is provided with a plurality of suction holes that pass through from top to bottom. The pressing unit is arranged above the folding core unit, and includes a movable pressing plate that can approach or move away from the folding core 901.

[0249] During operation, the core translation driving source 94 drives the pressing material moving bottom plate 93 to approach the lower cavity plate 51, so that the folding core 901 is placed in the lower cavity, and the air suction hole on the folding core 901 is connected with the negative pressure mechanism, and the lower cloth piece 7 can be fixed on the folding core 901 by negative pressure adsorption. At this time, the pressing plate is far away from the folding core 901 and will not interfere with the upper folding unit or the lower folding unit. After the upper folding unit and the lower folding unit work together to complete the folding and interlocking action of the trouser waist, the pressing plate moves down and presses the trouser waist tightly against the folding core 901, and then the core translation driving source 94 drives the pressing material moving bottom plate 93 away from the lower cavity plate 51, so that the folding core 901 exits the folding area, waiting for the material taking mechanism to take the material, and continue to complete the subsequent sewing work of the trouser waist.

[0250] As can be seen from the above, the automatic folding and interlocking device for trouser waist used in the present invention effectively eliminates the influence of the table gap between the lower cavity and the lower table 23 on the material transfer stability by setting the pressing cavity moving mechanism 9, thereby ensuring the smoothness and accuracy of the subsequent material transfer process.

[0251] In order to simultaneously complete the pressing and cavity shifting actions for the left and right waistbands and improve work efficiency, the number of folding core units and pressing units in the pressing cavity moving mechanism 9 is two, including a lower left folding core unit 92 and a lower right folding core unit 91 arranged on the pressing moving bottom plate 93, a left pressing unit 920 arranged above the lower left folding core unit 92, and a right pressing unit 910 arranged above the lower right folding core unit 91, and the right pressing unit 910 is connected to the pressing moving bottom plate 93 through a pressing bracket 905.

The lower left folding core unit 92 also includes a material pressing translation driving source 903 arranged on the material pressing moving bottom plate 93, and a material pressing telescopic bottom plate 904 slidably arranged on the material pressing moving bottom plate 93. The folding core 901 of the left material pressing unit 920 and the lower left folding core unit 92 are both arranged on the material pressing telescopic bottom plate 904. The material pressing telescopic bottom plate 904 approaches or moves away from the lower right folding core unit 91 under the drive of the material pressing translation driving source 903.

[0253] like Fig.23 As shown, the right pressing unit 910 includes a right pressing unit lifting driving source 916 connected to the pressing bracket 905 through a right pressing fixing plate 918, and the right pressing unit lifting driving source 916 is used to drive the right pressing lifting connecting plate 917 to move up and down. The right pressing lifting connecting plate 917 is connected to a pressing guide rail 912 extending in the front-to-back direction, and a pressing slider mounting plate 913 is slidably arranged on the pressing guide rail 912. One end of the pressing guide rail 912 is provided with a right pressing translation driving source 911, and the right pressing translation driving source 911 is connected to a floating joint connecting plate 9191 through a pressing floating joint 919, and the floating joint connecting plate 9191 is connected to the pressing slider mounting plate 913.

[0255] In summary, when the trouser waist automatic folding and interlocking device having the upper folding mechanism 1, the lower folding mechanism 2, the upper folding and feeding mechanism 8, the pressing cavity moving mechanism 9 and the material taking mechanism folds the upper fabric piece 6 and the lower fabric piece 7 of the trouser waist, the folding and interlocking process includes the steps of feeding, folding and interlocking, cavity moving and material taking. The specific folding and interlocking process is as follows:

[0256] Initial state: The cylinder piston rods of the first lifting drive source 31 and the second lifting drive source 111 are both in an extended state, and the third lifting drive source 113 makes the floating mounting plate 114 at a preset loading height. At this time, the distance between the upper cavity and the lower cavity is a preset distance, and the preset distance is specifically 30 mm. Each push plate, tongue plate, cloth block, upper expansion rod 464, and clamp jaw 473 in the upper folding unit and the lower folding unit are all outside the folding area. The cylinder piston rod of the upper clamp lifting drive source 477 is in an extended state, the clamp jaw 473 is in an open state, and the lower jaw 474 and the upper jaw 475 are symmetrical about the upper surface of the upper straight edge push plate 424. The cylinder piston rods of the first upper folding avoidance drive source 83 and the second upper folding avoidance drive source 85 are both in an extended state, and the cylinder piston rod of the upper folding feeding drive source 82 is in a retracted state. The upper folding feeding plate 88 is between the upper cavity and the lower cavity, and the spacing between them is the same. The cylinder piston rods of the core translation driving source 94 and the material pressing translation driving source 903 are both in a retracted state, and the folding core 901 is in the lower cavity. The material pressing plate is at the farthest distance from the folding core 901.

[0257] Loading: manually place the lower cloth piece 7 on the folding core 901, place the upper cloth piece 6 on the upper folding feed plate 88, and let the feed needle 89 pierce the cloth piece 6. Place the trouser placket on the lower clamp 474. The cylinder piston rod of the upper folding feed drive source 82 extends, drives the upper folding feed plate 88 to move upward, and feeds the upper cloth piece 6 into the upper cavity, and the upper cavity assembly 43 removes the upper cloth piece 6. Then the cylinder piston rod of the upper folding feed drive source 82 retracts, drives the upper folding feed plate 88 to move downward, and the upper cloth piece 6 is separated from the feed needle 89. The cylinder piston rods of the first upper folding avoidance drive source 83 and the second upper folding avoidance drive source 85 are both retracted, driving the upper folding feed plate 88 away from the upper cavity assembly 43 and exiting the folding area. The cylinder piston rod of the upper cloth block driving source 451 extends to drive the upper cloth block 452 to move downward, and the upper cloth block 452 passes through the upper cavity, so that the upper cloth piece is bent downward against the buckle edge 61 .

[0258] The specific process of removing the upper cloth sheet 6 from the upper cavity assembly 43 is as follows:

[0259] When the upper mold cavity assembly 43 adopts the structure of the first embodiment, the negative pressure mechanism works, and the upper cloth sheet 6 is adsorbed and fixed in the upper mold cavity due to the negative pressure.

[0260] When the upper cavity assembly 43 adopts the structure of the second embodiment, the acupuncture drive source 437 drives the acupuncture 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, thereby completing the fixing of the upper cloth piece 6.

[0261] The negative pressure mechanism works, and the lower cloth piece 7 is fixed in the lower cavity by suction 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 are extended, and then the cylinder piston rod of the lower side lifting drive source 524 is retracted, driving the lower side tongue plate 526 to press on the lower cloth piece 7.

[0262] Folding and interlocking: The folding action of the upper folding unit is as follows: the cylinder piston rod of the upper straight edge push plate driving source 422 extends, and the upper straight edge push plate 424 enters the upper mold cavity; the cylinder piston rod of the upper fixed push plate driving source 442 retracts, and the upper fixed push plate 443 enters the upper mold cavity, folding the two upper cloth pieces' non-buckled edges 62 inward into the upper mold cavity. Then the clamp jaws 473 are closed, and the upper jaws 475 and the lower jaws 474 clamp the trouser placket, so that the trouser placket is tightly attached to the bottom of the upper cloth piece's non-buckled edge 62 adjacent to the upper cloth piece's non-buckled side 611. The cylinder piston rod of the upper buckle edge push plate driving source 413 extends, driving the upper buckle edge push plate 412 to translate toward the upper mold cavity, and folding the upper cloth piece's non-buckled side 611 inward into the upper mold cavity. The upper buckle edge lifting drive source 417 drives its screw to rotate, so that the upper buckle edge lifting bracket 415 moves to the set pre-folding height, and then the cylinder piston rod of the upper buckle edge tongue plate driving source 414 extends, driving the upper buckle edge tongue plate 411 to translate toward the upper cavity, and pre-folding the buckle edge and buckle side 612 of the upper cloth piece inward into the upper cavity. The cylinder piston rods of the upper expansion rod first driving source 463 and the upper expansion rod second driving source 465 are both extended to drive the upper expansion rod 464 into the gap formed by the buckle edge and buckle side 612 of the folded upper cloth piece, and the shape of the gap is shaped so that the shape of the gap reaches a predetermined state. The cylinder piston rods of the upper expansion rod first driving source 463 and the upper expansion rod second driving source 465 are both retracted, and the upper expansion rod 464 is reset to exit the folding area.

[0263] The folding action of the lower folding unit is as follows: the cylinder piston rod of the lower straight edge push plate driving source 545 extends, driving the lower straight edge push plate 541 to move toward the lower cavity and press on the lower cloth piece 7. The cylinder piston rod of the lower side tongue plate driving source 521 retracts, driving the lower side tongue plate 526 to exit the lower cavity. The cylinder piston rod of the lower cloth block driving source 551 extends, driving the lower cloth block 552 to move upward and pass through the lower cavity plate 51, so that the first non-locking edge 71 of the lower cloth piece is bent upward. The cylinder piston rods of the lower side lifting drive source 524 and the lower side limit drive source 527 are both extended to drive the lower side tongue plate drive source 521 and the lower side push plate drive source 522 to move upward; the cylinder piston rods of the lower side tongue plate drive source 521 and the lower side push plate drive source 522 are both extended to drive the lower side tongue plate 526 and the lower side push plate 525 to move toward the lower cavity, and the lower side push plate 525 enters the lower cavity; at the same time, the cylinder piston rod of the lower side limit drive source 527 limits the stroke of the lower side tongue plate 526, so that the lower side tongue plate 526 partially enters the lower cavity, and the first non-locking edge 71 of the lower cloth piece is folded inward into the lower cavity. The folded state of the upper cloth piece 6 and the lower cloth piece 7 is shown in FIG. Fig.24 shown.

[0264] The folding actions of the upper folding unit and the lower folding unit can be performed simultaneously.

[0265] The third lifting drive source 113 drives its screw to rotate, so that the floating mounting plate 114 moves down to the pre-buckle height. The lower buckle edge lifting drive source 533 drives its screw to rotate, so that the lower buckle edge push plate 535 moves to the pre-folding height, and then the cylinder piston rod of the lower buckle edge push plate drive source 531 extends to drive the lower buckle edge push plate 535 to translate toward the lower cavity, inserting the lower cloth piece buckle edge 72 into the gap formed by the folded upper cloth piece buckle edge buckle side 612, so that the lower cloth piece buckle edge 72 and the upper cloth piece buckle edge buckle side 612 are pre-buckled, as shown in FIG. Fig.25 shown.

[0266] The third lifting drive source 113 drives its screw rod to rotate, so that the floating mounting plate 114 moves up to the closing height. In this process, step 1) and step 2) are performed simultaneously:

[0267] 1) The upper buckle edge lifting drive source 417 drives its screw to rotate, so that the upper buckle edge tongue plate 411 moves to the same height as the upper buckle edge push plate 412, and at the same time, the cylinder piston rod of the upper buckle edge guide drive source 416 extends to drive the upper buckle edge tongue plate 411 to fully enter the upper cavity;

[0268] 2) The lower buckle edge lifting drive source 533 drives its screw to rotate, so that the lower buckle 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 buckle edge guide drive source 534 extends to drive the lower buckle edge push plate 535 to completely enter the lower mold cavity.

[0269] At this point, the folding and interlocking of the trouser waist is completed. Fig.26 shown.

[0270] Cavity material transfer: The output end of the lifting drive source 431 passes through the through hole 4332 on the upper cavity plate 433, pressing the upper cloth piece 6 and the lower cloth piece 7 onto the folding core 901, and the trouser placket is located between the non-buttoning edge 62 of the upper cloth piece and the second non-buttoning edge 73 of the lower cloth piece. Subsequently, the upper cavity assembly 43 releases the fixation on the upper cloth piece 6, and the cylinder piston rods of the lower buckle edge guide drive source 534, the upper buckle edge tongue plate drive source 414, the upper buckle edge guide drive source 416, the upper buckle edge push plate drive source 413, the upper straight edge push plate drive source 422, the lower side tongue plate drive source 521, the lower side push plate drive source 522, the lower side limit drive source 527, the lower straight edge push plate drive source 545, the upper cloth block drive source 451 and the lower cloth block drive source 551 are all retracted, and the cylinder piston rod of the upper fixed push plate drive source 442 is extended. At this time, each push plate, tongue plate and cloth block in the upper folding unit and the lower folding unit exit the folding area. The clamp jaws 473 are opened, the cylinder piston rod of the upper clamp translation drive source 471 is extended, and the cylinder piston rod of the upper clamp lifting drive source 477 is retracted, driving the upper jaws 475 and the lower jaws 474 to be completely separated from the trouser placket. The third lifting drive source 113 is reset, and at the same time, the upper buckle edge lifting drive source 417 and the lower buckle edge lifting drive source 533 are reset. Then the pressing plate presses the trouser waist on the folding core 901. The cylinder piston rods of the lifting drive source 431 and the first lifting drive source 31 are retracted.

[0271] The cylinder piston rod of the core translation driving source 94 extends out, driving the pressing material moving bottom plate 83 to move forward and away from the lower cavity plate 51, and the folding core 901 and the left pressing plate 924 on the left, and the folding core 901 and the right pressing plate 915 on the right respectively move the two trouser waists away from the lower cavity plate 51 and exit the folding area. Then the cylinder piston rod of the pressing material translation driving source 903 extends out, driving the pressing material telescopic bottom plate 904 to move to the right, that is, the folding core 901 on the left and the left pressing plate 924 move to the right synchronously, and the distance between the left and right trouser waists is reduced to the sewing range of the pattern machine. At this time, the two folding cores 901 arrive at the material picking position, the cavity material moving action ends, and the material picking mechanism is waiting to pick up the material.

[0272] Material taking: the material taking mechanism moves to the material taking position, moves the trouser waist on the folding core 901 to the material loading position of the pattern machine, and the pattern machine receives the trouser waist and starts sewing.

[0273] Preferably, the method for resetting the above-mentioned trouser waist automatic folding and interlocking device provided by the present invention is as follows: Fig. 27 As shown, the following steps are included:

[0274] If the automatic folding and interlocking device for the trouser waist stops working when completing the feeding action or the folding and interlocking step, execute step S1: first control the upper buckle edge tongue plate 411 and the upper buckle edge push plate 412 of the upper buckle edge push plate assembly 41, and the lower buckle edge push plate 533 of the lower buckle edge push plate assembly 53 to exit the folding area respectively; then control the upper straight edge push plate 424 of the upper straight edge push plate assembly 42, the upper fixed push plate 443 of the upper fixed push plate assembly 44, the upper cloth stop block 452 of the upper cavity cloth stop assembly 45, the lower side edge push plate 525 and the lower side edge tongue plate 526 of the lower side edge push plate assembly 52, the lower straight edge push plate 541 of the lower straight edge push plate assembly 54, and the lower cloth stop block 552 of the lower cavity cloth stop assembly 55 to exit the folding area respectively, at this time, the upper folding mechanism 1 and the lower folding mechanism 2 will not interfere with each other. Then the floating mounting plate 114 is controlled to move upward, and the upper folding feed plate 88 exits the folding area. At this time, the upper folding mechanism 1, the lower folding mechanism 2, the upper folding feed mechanism 8 and the pressing cavity moving mechanism 9 will not interfere with each other; finally, the pressing cavity moving mechanism 9 and the picking mechanism are controlled to reset, so that the folding core 901 exits the folding area, the pressing plate is at the farthest distance from the folding core 901, and the picking mechanism leaves the picking position.

[0275] If the automatic folding and interlocking device for the waistband stops working when the cavity material moving step is completed, execute step S2: first control the folding core 901 to exit the folding area, the pressing plate is away from the folding core 901 and no longer presses the waistband, at this time, the pressing cavity moving mechanism 9 will not interfere with the upper folding mechanism 1, the lower folding mechanism 2 and the upper folding feeding mechanism 8; then control the first lifting drive source 31, the second lifting drive source 111 and the third lifting drive source 113 to make the floating mounting plate 114 move up to the highest point, and the upper folding mechanism 1 is away from the upper folding mechanism 1 at the same time. The lower folding mechanism 1 and the upper folding feeding mechanism 8 will not interfere with each other; finally, the lower folding mechanism 2, the upper folding feeding mechanism 8 and the material picking mechanism are controlled to reset, so that the lower side edge push plate 525 and the lower side edge tongue plate 526 of the lower side edge push plate assembly 52, the lower buckle side push plate 533 of the lower buckle side push plate assembly 53, the lower straight side push plate 541 of the lower straight side push plate assembly 54 and the lower cloth block 552 of the lower cavity cloth stopping assembly 55 exit the folding area, the upper folding feeding plate 88 exits the folding area, and the material picking mechanism leaves the material picking position.

[0276] If the automatic folding and interlocking device for the waistband stops working when the material picking step is completed, execute step S3: first control the material picking mechanism to leave the material picking position; then control the folding core 901 to exit the folding area, and the pressing plate to move away from the folding core 901, at this time, the pressing cavity moving mechanism 9 will not interfere with the upper folding mechanism 1, the lower folding mechanism 2 and the upper folding feeding mechanism 8; then control the first lifting drive source 31, the second lifting drive source 111 and the third lifting drive source 113, so that the floating mounting plate 114 moves up to the highest point , the upper folding mechanism 1 is away from the lower folding mechanism 1 and the upper folding feeding mechanism 8 at the same time, and there will be no interference between the three; finally, the lower folding mechanism 2 and the upper folding feeding mechanism 8 are controlled to reset, so that the lower side edge push plate 525 and the lower side edge tongue plate 526 of the lower side edge push plate assembly 52, the lower buckle side push plate 533 of the lower buckle side push plate assembly 53, the lower straight side push plate 541 of the lower straight side push plate assembly 54 and the lower cloth block 552 of the lower cavity cloth stop assembly 55 exit the folding area, and the upper folding feeding plate 88 exits the folding area.
