Description

Technical Field

[0001] This utility model relates to the field of bag opening machine equipment, and in particular to a compact bag processing mechanism. Background Technology

[0002] There are various types of pockets on clothing, including slip pockets, patch pockets, double-stitched pockets, and single-stitched pockets. To reduce labor costs and improve the efficiency of opening pockets in clothing, pocket opening machines are essential auxiliary processing machinery in the garment manufacturing process. They are mainly used to create pockets in specific locations on clothing, making it convenient to carry small items such as mobile phones and wallets. The traditional method is to first open the pocket opening and the pocket lip or a pocket lip with a pocket lining separately, and then sew the pocket lip or the pocket lip with the pocket lining onto the pocket opening to complete the pocket opening process. The pocket lining consists of two pieces of pocket lining. When only the pocket lip is sewn on, it is a false pocket; when the pocket lip with the pocket lining is sewn on, it is a true pocket.

[0003] The processing technology of the existing bag opening machine is as follows: First, the inner pressure frame of the material setting device closes to the outer pressure frame to position the bag opening of the garment. Then, the laser head of the laser cutting device cuts the bag opening. After the cutting is completed, the material setting device moves to the upper part of the lower support plate on which the bag lip with the bag fabric piece is placed, and the bag folding device performs the bag folding process. Then, the material setting device presses down so that the garment bag opening is stacked on the bag lip. Finally, it moves to the sewing station for sewing.

[0004] In the above process, because the folding device is located above the lower support plate, the translational stroke of the fixing device is relatively long during one bag processing cycle. Furthermore, the bag fabric piece can only be placed above the bag lip after the folding device has completed folding the bag opening, resulting in low efficiency. To further improve bag forming efficiency, Chinese utility model patent CN117966377A discloses a bag opening machine and bag opening sewing process. In this solution, the folding mechanism and the fixing mechanism are integrated and translated together, thereby completing the folding of the opening on the bag fabric piece during the joint translational process. However, for the driving of the folding mechanism and the fixing mechanism, this solution uses a motor and screw arranged inside the frame, with a base set on the screw. The base slides on the screw, thereby driving the folding mechanism and the fixing mechanism to move together. Since the combined weight of the folding mechanism and the fixing 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 are very large during the translation process. After long-term use, the slide rail and the base may even deform to a certain extent, resulting in poor structural stability. Therefore, it cannot meet the requirements of high-speed and high-frequency repetitive actions.

[0005] To address the aforementioned technical issues, I previously applied for a Chinese invention patent with patent number 202411510832.8. In this solution, a gantry frame is installed on the machine frame, and a first driving device and a translation frame are installed on the gantry frame. The first driving device can drive the translation frame, the material fixing mechanism, and the bag folding mechanism to move left and right together, thereby improving the translational stability of the material fixing mechanism and the bag folding mechanism. However, in this solution, since the translation frame includes a first sliding frame and a second sliding frame, with the first sliding frame arranged below the gantry frame and the second sliding frame arranged above the gantry frame (the first sliding frame is used to cooperate in installing the material fixing mechanism, and the second sliding frame is used to cooperate in installing the bag folding mechanism), this results in the translation frame occupying a large space. Consequently, a larger cover is required on the frame of the bag making machine to cover the gantry frame, necessitating improvement. Utility Model Content

Furthermore, since no structure is set above the gantry frame, it is also more convenient to install the cover on the frame, making it highly practical. Attached Figure Description

[0058] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0059] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0060] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0061] Detailed implementation plan: See below Figures 1-21 This utility model is a compact pocket processing mechanism, installed on a pocket machine. The pocket machine includes a frame 100, on which a work panel 110 is provided. The pocket processing mechanism includes:

[0062] A gantry frame 200 is installed above the work panel 110 and extends in the left and right directions. A first drive device 210 is provided on the gantry frame 200, which is used to drive the translation frame 220 to translate in the left and right directions. A second drive device 230 and a third drive device 240 are provided on the translation frame 220. A material fixing mechanism 300 is installed on the first drive device 210 through a first sliding frame 310. The second drive device 230 is used to drive the first sliding frame 310 to translate in the front and back directions.

[0063] The bag folding mechanism 400 is mounted on the second drive device 230 via the second sliding frame 410. The bag folding mechanism 400 is kept above the material fixing mechanism 300. The third drive device 240 is used to drive the second sliding frame 410 to translate in the front-back direction.

[0064] The second sliding frame 410 includes at least a translation main board 411 that is slidably mounted on the left or right side of the translation frame 220, and the translation main board 411 is linked to the third drive device 240.

[0065] As a preferred embodiment of this example, please refer to Figure 3 , Figure 4 and Figure 6 As can be seen, the translation mainboard 411 is slidably mounted on the right side of the translation frame 220, and the second sliding frame 410 also includes:

[0066] The translation subplate 413 is slidably installed on the left side of the translation frame 220;

[0067] The connecting plate 412 is fixed between the translation main plate 411 and the translation sub-plate 413, and is arranged above the translation frame 220.

[0068] Here, to ensure that the second sliding frame 410 can move smoothly back and forth along the translation frame 220, in this embodiment, the second sliding frame 410 is configured to include a translation main plate 411, a translation sub plate 413 and a connecting plate 412. The translation main plate 411 and the translation sub plate 413 are slidably installed on the left and right sides of the translation frame 220 through the sliding connection of sliders and slide rails, respectively.

[0069] Then, in this embodiment, the first sliding frame 310 is slidably installed below the translation frame 220, and the translation frame 220, the first sliding frame 310 and the second sliding frame 410 are all arranged below the gantry frame 200.

[0070] Here, the translation frame 220, the first sliding frame 310, and the second sliding frame 410 are all arranged below the gantry frame 200. The first drive device 210 for driving the first sliding frame 310 to move forward and backward, and the second drive device 230 for driving the second sliding frame 410 to move forward and backward, are both mounted on the translation frame 220. This makes the overall structure of the translation frame 220, the first drive device 210, the second drive device 230, the first sliding frame 310, and the second sliding frame 410 very compact and space-saving. Furthermore, the absence of a sliding frame above the gantry frame 200 facilitates the installation of the cover on the frame 100, further reducing the space occupied by the pocket machine.

[0071] For ease of understanding, although I have already provided a detailed explanation of the specific structure and working principle of the material feeding mechanism 300 and the bag folding mechanism 400 in my earlier Chinese invention patent application with patent number 202411510832.8, I will explain them again here:

[0072] Please see Figure 9 , Figure 10 and Figure 13As can be seen, in this embodiment, the material setting mechanism 300 is provided with a material setting plate 340 for placing the pocket fabric piece, and a fixing structure for fixing the pocket fabric piece. The material setting 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.

[0073] Then, in this embodiment, the material setting mechanism 300 includes a first sliding frame 310, on which a first mounting plate 311 arranged vertically is provided. The material setting mechanism 300 also includes:

[0074] The first lifting plate 330 is slidably mounted on the first mounting plate 311 in a vertical direction;

[0075] The first cylinder 320 is fixed on the second sliding frame 410 and is used to drive the first lifting plate 330 to rise and fall.

[0076] The fixed plate 340 is fixed on the first lifting plate 330, and the fixing structure consists of multiple pressing components fixed on the fixed plate 340.

[0077] The material outlet 377 adjustment component 370 is installed on the material plate 340 and is used to adjust the size of the material outlet 377. The material outlet 377 is used to accommodate the placement of the pocket fabric piece.

[0078] Then, please see Figures 9-16 As can be seen, in this embodiment, the pressing assembly includes a first pressing assembly 350, a second pressing assembly 360 and a third pressing assembly 380. The first pressing assembly 350 and the second pressing assembly 360 are used to work together to press down and fix the pocket fabric piece, and the third pressing assembly 380 is used to work together to press up the folded edge formed at the edge of the processing opening.

[0079] Here, the first pressing assembly includes:

[0080] The second cylinder 352 is fixed on the first lifting plate 330;

[0081] 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 lift.

[0082] Connecting plate 353 is fixed on second lifting plate 351;

[0083] The large pressure frame 354 is fixed on the connecting plate 353;

[0084] The front pressure strip 355 is fixed on the large pressure frame 354. Two side pressure strips 356 are fixed on the front pressure strip 355 with left and right spacing (the front pressure strip 355 is provided with multiple adjusting screw holes for adjusting the left and right positions of the side pressure strips 356).

[0085] The working principle of the first pressing assembly 350: When the fixing mechanism 300 is in the initial position, the pocket fabric piece needs to be placed on the 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 down on the front end and the left and right ends of the pocket fabric piece.

[0086] The second pressing assembly 360 includes:

[0087] Fixed bracket 361 is fixed above connecting plate 353;

[0088] The connecting block 363 is slidably mounted vertically on the fixed bracket 361;

[0089] The third cylinder 362 is mounted on the fixed bracket 361 and is used to drive the connecting block 363 to rise and fall.

[0090] The rear pressure strip 364 is fixed on the connecting block 363.

[0091] The working principle of the second pressing component 360: While the first pressing component 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, it can be driven to press the rear end of the pocket fabric piece downward.

[0092] Therefore, the first pressing assembly 350 and the second pressing assembly 360 work together to press the pocket fabric piece on top and fix its position.

[0093] In addition, in this embodiment, the lower ends of the front pressure strip 355, the rear pressure strip 364 and the side pressure strip 356 are all provided with pressure teeth, which can better press the pocket fabric piece downward.

[0094] The third pressing assembly 380 includes:

[0095] The sixth cylinder 381 is fixed on the fixed plate 340;

[0096] The lower pressure plate 382 is linked to the sixth cylinder 381 and is arranged below the material plate 340. The lower end surface of the material plate 340 is provided with an opening slot 341 adapted to the placement of the lower pressure plate 382. The lower pressure plate 382 is provided with an opening 383 corresponding to the sewing window 378.

[0097] In this embodiment, the operation of the third pressing component 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, driving the lower pressing plate 382 to rise and enter the opening groove 341. At this time, the lower pressing plate 382 will press the folded edge of the processing opening upward at the position corresponding to the opening 383, thereby fixing the folded edge.

[0098] Then, please see Figure 13 As can be seen, in this embodiment, the feed inlet adjusting component 370 includes:

[0099] There are two fourth cylinders 371, both of which are fixed on the fixed material plate 340. They are used to drive the front pull plate 372 to move back and forth. A front fixed material frame 373 is provided between the two front pull plates 372.

[0100] There are two fifth cylinders 374, both of which are fixed on the fixed material plate 340. They are used to drive the rear pull plate 375 to move back and forth. A rear fixed material frame 376 is provided between the two rear pull plates 375.

[0101] The front material frame 373 and the rear material frame 376 work together to form the material outlet 377.

[0102] Here, the front and rear material-fixing frames 373 and 376 work together to form the material-fixing opening 377. The front pull plate 372 is moved back and forth by the fourth cylinder 371, and the rear pull plate 375 is moved back and forth by the fifth cylinder 374, allowing adjustment of the front and rear width of the material-fixing opening 377 to accommodate pocket fabric pieces of different sizes. Note that the position of the material-fixing opening 377 corresponds to the position of the sewing window 378.

[0103] Then, please see Figure 11 As can be seen, in this embodiment, an upper cover plate 3100 is fixed to the upper end of the material fixing plate 340, and the upper cover plate 3100 is provided with a notch corresponding to the material fixing port 377. In addition, an external auxiliary plate 3110 is fixedly installed at the front end of the material fixing plate 340.

[0104] Next, please refer to Figure 12 and Figure 20 As can be seen in this embodiment, the lower end of the first lifting plate 330 is provided with two positioning sleeves 390. The positioning sleeves 390 are used to fix the circulating plate 500 below the material fixing mechanism 300. The rear end of the circulating plate 500 is provided with a rear block 530. The rear block 530 is provided with a pin 540 for inserting the positioning sleeves 390. The circulating plate 500 is provided with a through opening 510 corresponding to the sewing window 378.

[0105] Here, the forming accessories that need to be sewn together with the pocket fabric are placed on the circulating plate 500. The circulating plate 500 is fixed below the material setting mechanism 300 by the insertion of the pin 540 and the positioning sleeve 390, so that the forming accessories are placed close to the bottom of the pocket fabric, which is convenient for subsequent sewing processes.

[0106] In this embodiment, the bag folding mechanism 400 is in 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 fixing structure cooperates to keep the folded edge fixed.

[0107] In addition, the bag folding mechanism 400 includes a second sliding frame 410, a second mounting plate 414 fixed above the connecting plate 412, and the bag folding mechanism 400 also includes:

[0108] The third lifting plate 430 is vertically slidably mounted on the second mounting plate 414;

[0109] The seventh cylinder 420 is fixed on the fourth sliding frame and is used to drive the third lifting plate 430 to rise and fall.

[0110] The bottom plate 440 is fixed on the third lifting plate 430;

[0111] Two first folding assemblies 450 are mounted on the bottom plate 440 and are arranged at a distance from each other to fold the front and rear edges of the processing opening.

[0112] Two second folding assemblies 460 are mounted on the bottom plate 440 and are arranged at left and right intervals to fold the left and right edges of the processing opening.

[0113] In this embodiment, the first folding component 450 includes:

[0114] The eighth cylinder 451 is fixed to the bottom plate 440 by a mounting bracket;

[0115] The folding knife pull block 452 is linked to the eighth cylinder 451, which is used to drive the folding knife pull block 452 to move back and forth.

[0116] The first slider 453 is fixed on the folding knife pull block 452 and is slidably mounted above the bottom plate 440;

[0117] The lower plate 454 is fixed on the first slider 453 and extends below the lower plate 440;

[0118] The first folding blade 455 is fixed to the lower end of the lower connecting plate 454;

[0119] The second folding component 460 includes:

[0120] The ninth cylinder 461 is fixed to the base plate 440 by a mounting bracket;

[0121] The second slider 462 is linked to the ninth cylinder 461 and is slidably mounted on the bottom plate 440.

[0122] The tenth cylinder 464 is fixed on the second slider 462. The tenth cylinder 464 is used to drive the fourth lifting plate 463 to rise and fall.

[0123] The second folding blade 465 is fixed to the lower end of the fourth lifting plate 463.

[0124] Note that in this embodiment, the bottom plate 440 is provided with multiple clearance openings for the lower plate 454 to move back and forth and for the second slider 462 to move left and right. Furthermore, since the two first folding blades 455 need to be arranged in a front-to-back position, the lengths of the folding blade pull blocks 452 on the two first folding edge assemblies 450 are different, requiring one to be longer than the other.

[0125] The working principle of the folding mechanism 400: The folding ends of the folding mechanism 400, namely the first folding assembly 450 and the second folding assembly 460, are in the working state, i.e., when the folding mechanism 400 is positioned directly above the material fixing mechanism 300. The folding mechanism 400 is driven forward by the fourth driving device 260, causing its folding ends to be directly above the pocket fabric piece of the material fixing mechanism 300. Then, the seventh cylinder 420 drives the third lifting plate 430 to descend. Since the bottom plate 440 is fixed on the third lifting plate 430, and both the first folding assembly 450 and the second folding assembly 460 are mounted on the bottom plate 440, they are driven to descend together. During the descent, the first folding blade 455 of the first folding assembly 450 will first enter the processing opening of the pocket fabric piece. At this time, the second folding assembly 460 will work, specifically: the eighth cylinder 451 will work, and through the folding blade pull block 452 and the lower connecting plate 454, it will drive the two first folding blades 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 operates, specifically: the tenth cylinder 464 operates and drives the fourth lifting plate 463 to descend. Since the second folding blade 465 is fixed on the fourth lifting plate 463, both second folding blades 465 are driven into the processing opening of the pocket fabric piece. Then, the two ninth cylinders 461 operate and drive the two second sliders 462 to move away from each other. Since the tenth cylinder 464 is fixed on the second sliders 462, the fourth lifting plate 463 is linked and installed on the tenth cylinder 464. The second folding blades 465 are fixed at the lower end of the fourth lifting plate 463, thus driving the two second folding blades 465 to move away from each other, completing the folding of the left and right ends of the processing opening.

[0126] 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 is rectangular.

[0127] Here, by setting a third driving device 240, the folding bag mechanism 400 can be driven to translate in the front-back direction, and then the folding end of the folding bag mechanism 400 can be translated to be directly above the sewing window 378 according to the position of the sewing window 378 on the material setting mechanism 300.

[0128] Please see Figures 1-8 As can be seen, in this embodiment, the first driving device 210, the second driving device 230, and the third driving device 240 all adopt a motor lead screw structure, and the translation frame 220 is slidably mounted on the slide rail on the gantry frame 200 via a slider. The first sliding frame 310 and the second sliding frame 410 are also slidably mounted on the slide rail on the translation frame 220 via sliders. The motor lead screw structure, as well as the structural design of the slide rail and slider (to assist in smoother translation), are conventional prior art and will not be elaborated on here.

[0129] Then, please see Figure 3 As can be seen, a drag chain 280 is provided on one side of the gantry 200, and a fixed bracket 361 is provided between the translation frame 220 and the drag chain 280.

[0130] Here, by setting the drag chain 280, the first drive device 210 can drive the translation frame 220 to move left and right more smoothly.

[0131] For more details, please see Figure 3 and Figure 7 As can be seen, in this embodiment, the translation frame 220 is equipped with a first sensor 250, a second sensor 260 and a third sensor 270. The first sensor 250 is used to detect the left and right translation position of the translation frame 220, the second sensor 260 is used to detect the front and back translation position of the first sliding frame 310, and the third sensor 270 is used to detect the front and back translation position of the second sliding frame 410.
