Description

Technical Field

[0001] The utility model relates to the technical field of bag opening machine equipment, in particular to a highly efficient and stable bag processing mechanism. Background Art

[0002] There are many types of pockets on clothing, including insert pockets, patch pockets, double-stitch pockets, and single-stitch pockets. To reduce labor costs and improve pocket opening efficiency, pocket opening machines are essential auxiliary processing equipment during the garment processing process. They are primarily used to create pockets in specific locations on garments, conveniently storing small items such as mobile phones and wallets. Traditionally, the pocket opening and lip, or the lip with pocket fabric, are separately opened, and then the lip or the lip with pocket fabric is sewn onto the opening to complete the pocketing process. The pocket fabric is composed of two pieces of pocket fabric. When only the lip is sewn onto the opening, the pocket is a false pocket; when the lip with pocket fabric is sewn onto the opening, it becomes a true pocket.

[0003] The processing technology of the bag opening machine in the prior art is as follows: first, the inner pressure frame of the material fixing device is closed toward the outer pressure frame to position the pocket opening of the garment, and then the laser head of the laser cutting device completes the cutting of the pocket opening. After the cutting is completed, the material fixing device moves to the top of the lower support plate where the bag lip with the bag cloth piece is placed, and the bag folding device performs the bag folding process. Then the material fixing device is pressed down so that the pocket opening of the garment is overlapped on the bag lip, and finally the bag is moved to the sewing station for sewing.

[0004] In the above process, because the bag folding device is located above the lower support plate, the material setting device has a long translation stroke during a single bag production process. Furthermore, the bag fabric piece cannot be placed above the bag lip until the bag folding device has completed folding the bag opening, resulting in low efficiency. To further improve bag forming efficiency, Chinese utility model patent publication number CN117966377A discloses a bag opening machine and bag opening sewing process. In this solution, the folding mechanism and the material setting mechanism are integrated and translated together, completing the hem of the bag fabric opening during this translation process. However, for the drive of the folding mechanism and the dosing mechanism, this solution adopts a motor and a screw arranged inside the frame, and a base is set on the screw. The base slides on the screw to drive the folding mechanism and the dosing mechanism to translate together. Since the overall weight of the folding mechanism and the dosing mechanism is very heavy, when they are installed on the same base, the force on the base and the force between the base and the slide rail will be very large during the translation process. After long-term use, the slide rail and the base may even undergo certain deformation, and the structural stability is poor. Therefore, it cannot meet the requirements of high-speed and high-frequency repetitive actions. Utility Model Content

[0068] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0069] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0070] Furthermore, the terms "first," "second," and so forth, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one such feature. Furthermore, the technical solutions of various embodiments may be combined, but only if they are achievable by persons of ordinary skill in the art. If a combination of technical solutions contradicts or is unachievable, such combination shall be deemed non-existent and outside the scope of protection claimed by this utility model.

[0071] Specific implementation plan: see Figures 1-20 The utility model is an efficient and stable pocket processing mechanism, which is installed on a pocket machine. The pocket machine includes a frame 100, and a working panel 110 is provided on the frame 100. The pocket processing mechanism includes:

[0072] The gantry 200 is installed above the working panel 110 and extends in the left-right direction. The gantry 200 is provided with a first driving device 210 for driving the translation frame to translate in the left-right direction.

[0073] The material placement mechanism 300 is mounted on a translation frame, and the translation frame is provided with a second drive device 250 for driving the material placement mechanism 300 to translate in the front-to-back direction. The material placement mechanism 300 is provided with a placement plate 340 for cooperating to place the pocket fabric piece, and a fixing structure for fixing the pocket fabric piece. The placement plate 340 is provided with a sewing window 378, and the pocket fabric piece is provided with a processing opening corresponding to the sewing window 378 (this processing opening is formed by cutting the pocket fabric piece with a laser head, which is a prior art method);

[0074] The bag folding mechanism 400 is installed on the translation frame and remains above the material fixing mechanism 300. The bag folding mechanism 400 has a working state. In the working state, the bag folding end of the bag folding mechanism 400 descends to the material fixing mechanism 300 and folds the edge of the processing port. The fixed structure cooperates to keep the folded edge fixed.

[0075] As a preferred implementation of this embodiment, please refer to Figure 1-Figure 3It can be seen that the translation frame includes a first sliding frame 220 and a second sliding frame 240 arranged in an upper and lower position with an interval, and at least one fixed plate 230 is provided between the first sliding frame 220 and the second sliding frame 240. The first driving device 210 is installed on the first sliding frame 220, and the second driving device 250 is installed on the second sliding frame 240.

[0076] Then, in this embodiment, there are two fixed plates 230, and the two fixed plates 230 are respectively arranged on the front and rear sides of the gantry 200, the first sliding frame 220 is arranged below the gantry 200, and the second sliding frame 240 is arranged above the gantry 200.

[0077] Here, the two fixing plates 230 provide a very stable connection between the first sliding frame 220 and the second sliding frame 240, thereby allowing the first sliding frame 220, the second sliding frame 240, and the fixing plates 230 to collectively form an integrated translation frame. Therefore, when the first driving device 210 drives the first sliding frame 220 to translate left and right, it is equivalent to driving the entire translation frame to translate left and right.

[0078] In addition, referring to 20, it can be seen that in this embodiment, a first drag chain 270 is provided on one side of the first sliding frame 220, and a second drag chain 280 is provided on one side of the second sliding frame 240. The setting of the first drag chain 270 and the second drag chain 280 can make the left and right translation of the translation frame more stable when the first driving device 210 drives the translation frame.

[0079] See also Figure 5-Figure 8 It can be seen that in this embodiment, the material setting mechanism 300 includes:

[0080] A third sliding frame 310 is installed below the second driving device 250. The third sliding frame 310 is provided with a first mounting plate 311 arranged vertically;

[0081] The first lifting plate 330 is vertically slidably mounted on the first mounting plate 311;

[0082] The first cylinder 320 is fixed on the third sliding frame 310 and is used to drive the first lifting plate 330 to move up and down;

[0083] The fixing plate 340 is fixed on the first lifting plate 330, and the fixing structure is a plurality of pressing components fixed on the fixing plate 340;

[0084] The material fixing opening 377 positioning component 370 is installed on the material fixing plate 340 and is used to adjust the size of the material fixing opening 377. The material fixing opening 377 is used to accommodate the pocket cloth pieces.

[0085] Then, see Figure 5 、 Figure 6 、 Figure 11 and Figure 12 In this embodiment, the pressing assembly includes a first pressing assembly 350, a second pressing assembly 360 and a third pressing assembly 380, wherein the first pressing assembly 350 and the second pressing assembly 360 are used to cooperate with each other to press down and fix the pocket cloth piece, and the third pressing assembly 380 is used to cooperate with the upward pressing to form a fold at the edge of the processing opening.

[0086] Here, the first pressing assembly includes:

[0087] The second cylinder 352 is fixed on the first lifting plate 330;

[0088] The second lifting plate 351 is slidably mounted on the first lifting plate 330 , and the second cylinder 352 is used to drive the second lifting plate 351 to move up and down;

[0089] The connecting plate 353 is fixed on the second lifting plate 351;

[0090] Large pressing frame 354, fixed on connecting plate 353;

[0091] The front pressure strip 355 is fixed on the large pressure frame 354. Two side pressure strips 356 arranged at intervals on the left and right are fixed on the front pressure strip 355 (the front pressure strip 355 is provided with multiple adjustment screw holes for adjusting the left and right positions of the side pressure strips 356).

[0092] The working principle of the first pressing assembly 350: when the material fixing mechanism 300 is located at the initial work position, it is necessary to place the pocket cloth piece on the material fixing port 377. At this time, the second cylinder 352 works and drives the first lifting plate 330 to descend. Since the connecting plate 353 is fixed on the second lifting plate 351, the large pressing frame 354 is fixed on the connecting plate 353, the front pressing strip 355 is fixed on the large pressing frame 354, and the side pressing strip 356 is fixed on the front pressing strip 355, the front pressing strip 355 and the side pressing strip 356 can be driven downward to press the front end and left and right ends of the pocket cloth piece.

[0093] The second pressing assembly 360 includes:

[0094] A fixed bracket 361 is fixed above the connecting plate 353;

[0095] The connecting block 363 is mounted on the fixing bracket 361 in a vertical sliding manner;

[0096] The third cylinder 362 is mounted on the fixed bracket 361 and is used to drive the connecting block 363 to move up and down;

[0097] The rear pressure strip 364 is fixed on the connecting block 363 .

[0098] The working principle of the second pressing assembly 360: while the first pressing assembly 350 is working, the third cylinder 362 works and drives the connecting block 363 to descend. Since the rear pressing strip 364 is fixed on the connecting block 363, the rear pressing strip 364 can be driven downward to press the rear end of the pocket cloth piece.

[0099] Therefore, the first pressing assembly 350 and the second pressing assembly 360 cooperate with each other to press the pocket cloth piece from above and fix the position of the pocket cloth piece.

[0100] In addition, in this embodiment, the lower ends of the front pressing strip 355 , the rear pressing strip 364 and the side pressing strip 356 are all provided with pressing teeth, thereby better pressing the pocket fabric downwards.

[0101] The third pressing assembly 380 includes:

[0102] The sixth cylinder 381 is fixed on the fixed plate 340;

[0103] The lower pressing plate 382 is linked to the sixth cylinder 381 and is arranged below the fixing plate 340. The lower end surface of the fixing plate 340 is provided with an opening groove 341 for fitting the lower pressing plate 382. The lower pressing plate 382 is provided with an opening 383 corresponding to the sewing window 378.

[0104] In this embodiment, the work of the third pressing assembly 380 needs to be carried out after the bag folding mechanism 400 folds the edge of the processing opening. After the bag folding end of the bag folding mechanism 400 folds the edge of the processing opening, the sixth cylinder 381 works to drive the lower pressure plate 382 to rise and enter the opening groove 341. At this time, the position of the lower pressure plate 382 corresponding to the opening 383 will press the folded edge of the processing opening upward, thereby achieving the fixation of the folded edge.

[0105] Then, see Figure 13 As can be seen, in this embodiment, the positioning assembly 370 of the material port 377 includes:

[0106] There are two fourth cylinders 371, both fixed on the material fixing plate 340, used to drive the front pull plate 372 to move forward and backward. A front material fixing frame 373 is provided between the two front pull plates 372;

[0107] There are two fifth cylinders 374, both fixed on the material setting plate 340, used to drive the rear pull plate 375 to move forward and backward. A rear material setting frame 376 is provided between the two rear pull plates 375;

[0108] The front dosing frame 373 and the rear dosing frame 376 cooperate to form a dosing opening 377 .

[0109] Here, the front and rear feed frames 373 and 376 work together to form a feed opening 377. The fourth cylinder 371 drives the front pull plate 372 to translate forward and backward, while the fifth cylinder 374 drives the rear pull plate 375 to translate forward and backward. This allows the width of feed opening 377 to be adjusted to accommodate pocket fabrics of varying sizes. Note that the position of feed opening 377 corresponds to the position of sewing window 378.

[0110] Then, see Figure 12 It can be seen that in this embodiment, the upper end of the fixing plate 340 is fixed with an upper cover plate 3100, and a notch corresponding to the fixing opening 377 is provided on the upper cover plate 3100. In addition, an external auxiliary plate 3110 is fixedly installed at the front end of the fixing plate 340.

[0111] See also Figure 9 、 Figure 10 and Figure 15 In this embodiment, two positioning sleeves 390 are provided at the lower end of the first lifting plate 330. The positioning sleeves 390 are used to cooperate with the circulation plate 500 to fix it under the material fixing mechanism 300. The rear end of the circulation plate 500 is provided with a rear block 530. The rear block 530 is provided with a pin 540 for cooperating with the positioning sleeve 390. The circulation plate 500 is provided with a through opening 510 corresponding to the sewing window 378.

[0112] Here, the forming auxiliary parts that need to be sewn together with the pocket cloth pieces are placed on the circulation plate 500. The circulation plate 500 is fixed under the material fixing mechanism 300 by plugging the pin 540 and the positioning sleeve rod 390, so that the forming auxiliary parts can be placed closely under the pocket cloth pieces, which is convenient for the subsequent sewing process.

[0113] Also, see Figure 20 As can be seen, in this embodiment, the working panel 110 is provided with suction holes, and the circulation plate 500 is provided with a plurality of through holes 520 corresponding to the areas where the suction holes are located. The through holes 520 are distributed around the opening 510. The pocket machine is equipped with a fan, which absorbs and positions the molding accessories placed on the circulation plate 500 through the suction holes and through holes 520.

[0114] Next, see Figure 16-Figure 18 , it can be seen that, in this embodiment, the bag folding mechanism 400 includes:

[0115] A fourth sliding frame 410 is installed above the third driving device 260. The fourth sliding frame 410 is provided with a second mounting plate 411 arranged vertically;

[0116] The third lifting plate 430 is vertically slidably mounted on the second mounting plate 411;

[0117] The seventh cylinder 420 is fixed on the fourth sliding frame 410 and is used to drive the third lifting plate 430 to move up and down;

[0118] The bottom connecting plate 440 is fixed on the third lifting plate 430;

[0119] Two first folding assemblies 450 are mounted on the bottom plate 440 and arranged in a front-to-back spacing, and are used to fold the front and back edges of the processing opening;

[0120] The two second folding assemblies 460 are mounted on the bottom connecting plate 440 and spaced apart on the left and right sides, and are used to fold the left and right edges of the processing opening.

[0121] More specifically, the first hemming assembly 450 includes:

[0122] The eighth cylinder 451 is fixed to the bottom plate 440 via a mounting bracket;

[0123] The folding knife pull block 452 is linked to the eighth cylinder 451, and the eighth cylinder 451 is used to drive the folding knife pull block 452 to move forward and backward;

[0124] The first slider 453 is fixed to the folding knife pull block 452 and is slidably mounted above the bottom plate 440;

[0125] The lower connecting plate 454 is fixed to the first slider 453 and extends below the bottom connecting plate 440;

[0126] A first folding knife 455 is fixed to the lower end of the lower connecting plate 454;

[0127] The second hemming assembly 460 includes:

[0128] The ninth cylinder 461 is fixed to the bottom plate 440 via a mounting bracket;

[0129] The second slider 462 is linked to the ninth cylinder 461 and is slidably mounted on the bottom plate 440;

[0130] The tenth cylinder 464 is fixed on the second slider 462 and is used to drive the fourth lifting plate 463 to move up and down;

[0131] The second folding knife 465 is fixed to the lower end of the fourth lifting plate 463 .

[0132] Note that in this embodiment, the bottom connecting plate 440 is provided with multiple openings for the front-to-back translation of the lower connecting plate 454 and the left-to-right translation of the second slider 462. Furthermore, since the two first folding knives 455 need to be arranged in a front-to-back position, the folding knife pull blocks 452 on the two first hemming assemblies 450 need to be of different lengths, with one longer and one shorter.

[0133] The working principle of the bag folding mechanism 400: The bag folding ends of the bag folding mechanism 400, namely the first folding assembly 450 and the second folding assembly 460, are in the working state, that is, when the bag folding mechanism 400 remains directly above the material setting mechanism 300, the bag folding mechanism 400 is driven forward and translated by the fourth drive device 260, so that its bag folding ends are directly above the pocket fabric of the material setting mechanism 300. Then, the seventh cylinder 420 drives the third lifting plate 430 to descend. Because the bottom plate 440 is fixed to the third lifting plate 430, the first folding assembly 450 and the second folding assembly 460 are both mounted on the bottom plate 440, which drives the first folding assembly 450 and the second folding assembly 460 to descend together. During the descending process, the first folding knife 455 of the first folding assembly 450 will first enter the processing opening of the pocket cloth piece. At this time, the second folding assembly 460 works, specifically: the eighth cylinder 451 works, and through the folding knife pull block 452 and the lower connecting plate 454, drives the two first folding knives 455 to move away from each other, completing the folding of the front and rear ends of the processing opening. Next, the second folding assembly 460 works, specifically: the tenth cylinder 464 works and drives the fourth lifting plate 463 to descend. Since the second folding knife 465 is fixed on the fourth lifting plate 463, the two second folding knives 465 are driven to enter the processing opening of the pocket cloth piece. Then, the two ninth cylinders 461 work and drive the two second sliders 462 to face away from each other. Since the tenth cylinder 464 is fixed on the second slider 462, the fourth lifting plate 463 is installed on the tenth cylinder 464 in a linkage manner, and the second folding knife 465 is fixed at the lower end of the fourth lifting plate 463, and the two second folding knives 465 can be driven to face away from each other, completing the folding of the left and right ends of the processing opening.

[0134] In this embodiment, after the front and rear ends, as well as the left and right ends of the processing opening are folded, the processing opening appears to be a rectangle.

[0135] Then, see Figure 1 、 Figure 4 and Figure 17 It can be seen that in this embodiment, the second sliding frame 240 is provided with a third driving device 260 for driving the bag folding mechanism 400 to translate in the front-to-back direction. In the working state, the bag folding end of the bag folding mechanism 400 translates forward to just above the pocket cloth piece.

[0136] Here, by setting up a third driving device 260, the bag folding mechanism 400 can be driven to translate in the front-to-back direction, and then the bag folding end of the bag folding mechanism 400 can be translated to just above the sewing window 378 according to the position of the sewing window 378 on the material fixing mechanism 300.

[0137] Of course, if the third drive device 260 is not provided, the bag folding end of the bag folding mechanism 400 must be positioned directly above the sewing window 378. In this case, the positions of the laser head used to cut the processing openings in the pocket fabric and the sewing head used to sew the pocket fabric and the forming accessories in the pocket making machine need to be adjusted to prevent the laser head or the sewing head from being easily touched during the translation of the bag folding mechanism 400 and the material setting mechanism 300.

[0138] See also Figure 3-Figure 6 ,as well as Figure 17 As can be seen, in this embodiment, the first drive device 210, the second drive device 250, and the third drive device 260 all utilize a motor-screw structure, and the first sliding frame 220 is slidably mounted on the slide rails of the gantry frame 200 via a slider (since the first sliding frame 220 is part of the translation frame, it is equivalent to the translation frame being slidably mounted on the slide rails of the gantry frame 200). The third sliding frame 310 is slidably mounted on the slide rails of the first sliding frame 220 via a slider, and the fourth sliding frame 410 is slidably mounted on the slide rails of the second sliding frame 240 via a slider. The motor-screw structure, as well as the structural design of the slide rails and sliders (which assist in smoother translation), are conventional prior art and will not be elaborated upon here.

[0139] The driving structure formed by the gantry 200, the motor lead screw and the translation frame can drive the material setting mechanism 300 and the bag folding mechanism 400 to move left and right very smoothly and at high speed. After long-term use, the structure of the gantry 200 and the translation frame will not be damaged due to pressure, and the service life is extended.

[0140] The above description of an efficient and stable pocket processing mechanism of the present invention is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
