Description

Technical Field

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

[0002] There are many types of pockets on clothing, including insert pockets, patch pockets, double-stitched pockets, single-stitched pockets, etc. In order to reduce labor costs and improve the efficiency of opening pockets for clothing, pocket opening machines are essential auxiliary processing machines in the clothing processing process. They are mainly used to form pockets at specific locations on clothing to facilitate carrying small items such as mobile phones and wallets. The traditional method is to first open the pocket opening and the pocket lip or the pocket lip with pocket cloth separately, and then sew the pocket lip or the pocket lip with pocket cloth to the pocket opening to complete the pocket opening process. The pocket cloth is composed of two pieces of pocket cloth. The pocket opening is a fake pocket when only the pocket lip is sewn, and a real pocket when the pocket lip with pocket cloth is sewn.

[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 pocket opening is cut by the laser head of the laser cutting device. 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, and then the material fixing device is pressed down so that the pocket opening of the garment is overlapped on the bag lip, and finally moves to the sewing station for sewing.

[0004] In the above process, since the bag folding device is arranged above the lower support plate, the translation stroke of the material setting device is relatively long during one bag processing process, and the bag cloth piece can only be placed above the bag lip after the bag folding device completes the bag folding work on the bag mouth, resulting in low working efficiency. In order to further improve the efficiency of bag forming, the Chinese invention patent with publication number CN117966377A discloses a bag opening machine and bag mouth sewing processing technology. In this solution, the folding mechanism and the material setting mechanism are integrated together and translated together, and then the folding of the opening on the bag cloth piece is completed during the common translation process. However, for the driving 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 sliding of the base on the screw drives 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 be deformed to a certain extent, and the structural stability is poor. Therefore, it cannot meet the requirements of high-speed and high-frequency repetitive actions. Summary of the invention

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0071] Specific implementation plan: see Figure 1-Figure 20 The present invention 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, and the first driving device 210 is used to drive the translation frame to translate in the left-right direction;

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

[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 opening. The fixed structure cooperates to keep the folded edge fixed.

[0075] As a preferred implementation of this embodiment, please refer to Figure 1-Figure 3 It can be seen that the translation frame includes a first sliding frame 220 and a second sliding frame 240 which are arranged in an upper and lower position with an interval, 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 at 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 connection between the first sliding frame 220 and the second sliding frame 240 can be very stable through the two fixing plates 230, so that the first sliding frame 220, the second sliding frame 240 and the fixing plates 230 together form an integral 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 smoother 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, and a first mounting plate 311 arranged vertically is provided on the third sliding frame 310;

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

[0084] The material fixing opening 377 positioning assembly 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 , Fig.11 and Fig.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 upward pressing to form a folded edge at the edge of the processing opening.

[0086] Here, the first pressing component includes:

[0087] A second cylinder 352, 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] A connecting plate 353, fixed on the second lifting plate 351;

[0090] A large pressing frame 354 is fixed on the connecting plate 353;

[0091] The front pressure strip 355 is fixed on the large pressure frame 354 , and 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 a plurality of 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 working 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 to press the front end and the left and right ends of the pocket cloth piece downward.

[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 slidably mounted on the fixing bracket 361 in a vertical direction;

[0096] The third cylinder 362 is installed on the fixed bracket 361 and is used to drive the connection block 363 to rise and fall;

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

[0098] The working principle of the second pressing assembly 360 is as follows: 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, so as to better press the pocket cloth piece downwards.

[0101] The third pressing assembly 380 includes:

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

[0103] The lower pressing plate 382 is linked to the sixth cylinder 381 and arranged below the fixing plate 340. The lower end surface of the fixing plate 340 is provided with an opening groove 341 adapted to place 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. When 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 Fig.13 It can be seen that in this embodiment, the positioning assembly 370 of the fixed material port 377 includes:

[0106] There are two fourth cylinders 371, both of which are fixed on the material fixing plate 340, and are 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 of which are fixed on the material fixing plate 340, and are used to drive the rear pull plate 375 to move forward and backward. A rear material fixing frame 376 is provided between the two rear pull plates 375;

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

[0109] Here, the front material setting frame 373 and the rear material setting frame 376 cooperate to form a material setting opening 377. The fourth cylinder 371 drives the front pull plate 372 to translate forward and backward, and the fifth cylinder 374 drives the rear pull plate 375 to translate forward and backward, so that the front and rear width of the material setting opening 377 can be adjusted, so that pocket fabrics of different sizes can be placed. Note that the position of the material setting opening 377 corresponds to the position of the sewing window 378.

[0110] Then, see Fig.12It can be seen that in this embodiment, an upper cover plate 3100 is fixed to the upper end of the fixing plate 340, 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 on the front end of the fixing plate 340.

[0111] See also Fig. 9 , Fig.10 and Fig.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. A rear block 530 is provided at the rear end of the circulation plate 500. The rear block 530 is provided with a pin 540 for cooperating with the positioning sleeves 390. The circulation plate 500 is provided with a through opening 510 corresponding to the sewing window 378.

[0112] Here, the circulation plate 500 is provided with molding auxiliary parts that need to be sewn together with the pocket cloth pieces. 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 molding auxiliary parts can be placed closely under the pocket cloth pieces, which is convenient for the subsequent sewing process.

[0113] Also, see Fig. 20 It can be seen that 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, and the through holes 520 are distributed around the through opening 510. The pocket machine is provided with a fan, and the fan adsorbs and positions the molding auxiliary placed on the circulation plate 500 through the suction holes and the through holes 520.

[0114] Next, see Figure 16-18 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, and a second mounting plate 411 arranged vertically is provided on the fourth sliding frame 410;

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

[0119] Two first folding components 450 are mounted on the bottom connecting 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] Two second folding assemblies 460 are mounted on the bottom connecting plate 440 and arranged at intervals 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 by means of 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 sliding block 453 is fixed on the folding knife pull block 452 and is slidably mounted above the bottom connecting plate 440;

[0125] The lower connecting plate 454 is fixed on the first sliding block 453 and extends below the bottom connecting plate 440;

[0127] The second hemming assembly 460 includes:

[0128] The ninth cylinder 461 is fixed to the bottom plate 440 by means of 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 a plurality of openings for the bottom connecting plate 454 to move forward and backward, and for the second sliding block 462 to move left and right. In addition, since the two first folding knives 455 need to be arranged in a front-to-back position, the lengths of the folding knife pull blocks 452 on the two first folding edge assemblies 450 are different, and one needs to be long and the other short.

[0133] Working principle of the bag folding mechanism 400: The bag folding end of the bag folding mechanism 400, namely the first folding assembly 450 and the second folding assembly 460, is in the working state, that is, when the bag folding mechanism 400 is kept directly above the material fixing mechanism 300, the bag folding mechanism 400 is driven to translate forward by the fourth driving device 260, and its bag folding end is directly above the pocket cloth piece of the material fixing mechanism 300. Then, the seventh cylinder 420 drives the third lifting plate 430 to descend. Since the bottom connecting plate 440 is fixed on the third lifting plate 430, the first folding assembly 450 and the second folding assembly 460 are both installed on the bottom connecting plate 440, thereby driving the first folding assembly 450 and the second folding assembly 460 to descend together. During the descent, 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 component 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 move 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 on the lower end of the fourth lifting plate 463, the two second folding knives 465 can be driven to move 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 presents a rectangular shape.

[0135] Then, see Figure 1 , Figure 4 and Fig.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 along the front-rear 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 driving device 260 is not provided, the bag folding end of the bag folding mechanism 400 needs to be directly arranged above the sewing window 378. In this way, it is necessary to adjust the positions of the laser head used for cutting the processing opening on the pocket fabric piece and the sewing machine head used for sewing the pocket fabric piece and the forming auxiliary parts in the pocket machine to prevent the laser head or the sewing machine head from being easily touched during the translation process of the bag folding mechanism 400 and the material setting mechanism 300.

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

[0139] The driving structure formed by the gantry 200, the motor lead screw and the translation frame can drive the material fixing mechanism 300 and the bag folding mechanism 400 to translate left and right very smoothly 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 longer.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
