Description

Technical Field

[0001] This utility model relates to the field of bag opening machine equipment, and in particular to a bag folding mechanism based on motor-driven lifting. 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] To improve the translational stability of the material positioning mechanism and the folding mechanism, I previously filed a Chinese invention patent application (application number 202411510832.8) entitled "An Automated Garment Pocket Forming Machine." Additionally, to reduce the space occupied by the equipment, I subsequently filed a utility model patent application (application number 202423009397.9) entitled "A Compact Pocket Processing Mechanism." In practical applications, I have found that in the prior art (referring to the technical solutions disclosed in the aforementioned patents), the driving and lifting of the folding mechanism uses a cylinder drive. Cylinder drives can only control the initial and final positions of the stroke, making fine-tuning difficult. When the folding blade of the folding mechanism folds the edge of the pocket fabric pressed against the positioning mechanism, the folding blade needs to be tightly pressed against the edge of the pocket fabric to ensure folding quality. If the folding blade's descent position is not correct, it may result in an unsatisfactory fold. In addition, after the folding is completed, the lower pressure plate of the positioning mechanism will press the folded edge upward. At this time, the folding knife needs to be withdrawn upward. When the folding knife and the folded edge are in close contact, the folded edge pressed by the lower pressure plate may be pulled out during the upward withdrawal of the folding knife, which will affect the folding quality and needs to be improved. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a bag-folding mechanism based on motor-driven lifting.

[0006] The technical solution adopted in this utility model is: a bag folding mechanism based on motor-driven lifting, mounted on a third driving device, the third driving device being mounted on a translation frame, the translation frame being driven by a first driving device to move left and right along a gantry frame, the bag folding mechanism including a second sliding frame linked to the third driving device, and the bag folding mechanism further including:

[0007] The motor drive device includes at least a motor base fixed on a second sliding frame, a drive motor fixed on the motor base, and a transmission assembly linked to the drive motor. At least one bearing seat is also installed on the second sliding frame. A lead screw is passed through the bearing seat. The lead screw is arranged vertically and one end is linked to the transmission assembly. A nut seat is installed on the lead screw.

[0008] The third lifting plate is fixed to one side of the nut seat;

[0009] The bottom plate is fixed to the third lifting plate;

[0010] Two first folding assemblies are mounted on the bottom plate and arranged at a distance from each other to fold the front and back edges of the processing opening of the pocket fabric piece.

[0011] Two second folding components are mounted on the bottom plate and arranged at left and right intervals to fold the left and right edges of the processing opening of the pocket fabric piece.

[0012] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0013] Preferably, the transmission assembly includes a drive wheel linked to the drive motor, a driven wheel fixed to the lower end of the lead screw, and a synchronous belt disposed between the drive wheel and the driven wheel.

[0014] Preferably, the second sliding frame includes:

[0015] The translation main board is slidably mounted on the right side of the translation frame and is linked to the third drive device mounted on the translation frame;

[0016] A translation subplate is slidably mounted on the left side of the translation frame;

[0017] A connecting plate is fixed between the main translation plate and the secondary translation plate, and is arranged above the translation frame.

[0018] Preferably, the second sliding frame further includes a second mounting plate fixed above the connecting plate, and the bearing seat is fixedly mounted on the second mounting plate.

[0019] Preferably, at least one sensor is mounted on the second mounting plate, the sensor being used to sense the starting position of the nut seat.

[0020] Preferably, the first folding component includes:

[0021] The seventh cylinder is fixed to the bottom plate by a mounting bracket;

[0022] The folding knife pull block is linked to the seventh cylinder, which is used to drive the folding knife pull block to move back and forth.

[0023] The first slider is fixed to the folding knife pull block and slidably mounted above the bottom plate;

[0024] The lower plate is fixed on the first slider and extends below the lower plate;

[0029] The ninth cylinder is fixed on the second slider and is used to drive the fourth lifting plate to rise and fall.

[0030] The second folding blade is fixed to the lower end of the fourth lifting plate.

[0031] Compared with the prior art, this utility model has the following beneficial effects:

[0032] 1. The drive motor, transmission components, and lead screw work together to drive the nut seat to rise and fall along the lead screw. Since the third lifting plate is fixed on one side of the nut seat, the third lifting plate, the bottom plate, the first folding edge component, and the second folding edge component set on the third lifting plate can be driven to rise and fall, resulting in more precise control.

[0033] 2. When the first and second folding blades are folding the edge of the pocket fabric, the drive motor controls the first and second folding blades to descend slightly to ensure that the folded edge on the pocket fabric is pressed tightly. When the lower pressure plate of the positioning mechanism presses the folded edge upward, the drive motor again controls the first and second folding blades to descend slightly so that the first and second folding blades do not come into close contact with the folded edge. During the upward retraction of the first and second folding blades, neither the first nor the second folding blade will pull the folded edge out. Attached Figure Description

[0051] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0052] 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.

[0053] 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.

[0054] 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 with "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.

[0055] Detailed implementation plan: See below Figures 1-15 This utility model is a bag folding mechanism based on motor-driven lifting. It is mounted on a third driving device, which is installed on a translation frame 600. The translation frame 600 is driven by a first driving device to move left and right along a gantry frame. The bag folding mechanism 400 includes a second sliding frame 410 linked to the third driving device. The bag folding mechanism 400 also includes:

[0056] The motor drive device 420 includes at least a motor base 421 fixed on the second sliding frame 410, a drive motor 422 fixed on the motor base 421, and a transmission assembly linked to the drive motor 422. At least one bearing seat 426 is also installed on the second sliding frame 410. A lead screw 427 is threaded through the bearing seat 426. The lead screw 427 is arranged vertically and one end is linked to the transmission assembly. A nut seat 428 is installed on the lead screw 427. A third lifting plate 430 is fixed to one side of the nut seat 428.

[0057] The bottom plate 440 is fixed on the third lifting plate 430;

[0058] 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 of the pocket fabric piece.

[0059] 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 of the pocket fabric piece.

[0060] Please see Figure 4 As can be seen, in this embodiment, the transmission assembly includes a drive wheel 423 that is linked to the drive motor 422, a driven wheel 424 that is fixed to the lower end of the lead screw 427, and a synchronous belt 425 disposed between the drive wheel 423 and the driven wheel 424.

[0061] The working principle of the motor drive device 420: The drive motor 422 works and drives the driving wheel 423 to rotate. Since there is a synchronous belt 425 between the driven wheel 424 and the driving wheel 423, the driven wheel 424 is driven to rotate. Since the lower end of the lead screw 427 is fixed on the driven wheel 424, the lead screw 427 can be driven to rotate. Since the nut seat 428 is installed on the lead screw 427, when the lead screw 427 rotates, it will drive the nut seat 428 to move up and down along the lead screw 427, thereby driving the third lifting plate 430 fixed on the nut seat 428 to move up and down. Since the bottom plate 440 is fixed on the third lifting plate 430, the first folding assembly 450 and the second folding assembly 460 are installed on the bottom plate 440, thereby driving the bottom plate 440, the first folding assembly 450 and the second folding assembly 460 to move up and down together with the third lifting plate 430.

[0062] Next, please refer to Figure 2 As can be seen, in this embodiment, the second sliding frame 410 includes:

[0063] The translation main board 411 is slidably mounted on the right side of the translation frame 600 and is linked to the third drive device mounted on the translation frame 600;

[0064] The translation subplate 413 is slidably installed on the left side of the translation frame 600;

[0065] 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 600.

[0066] Regarding the structural design of the second sliding frame 410, since it has already been described in previous patent documents, it will not be elaborated further here.

[0067] Please see Figure 2 As can be seen, the second sliding frame 410 also includes a second mounting plate 414 fixed above the connecting plate 412, and the bearing seat 426 is fixedly mounted on the second mounting plate 414.

[0068] In addition, please see Figure 2In this embodiment, at least one sensor 429 is installed on the second mounting plate 414. The sensor 429 is used to sense the starting position of the nut seat 428. When the sensor 429 senses that the nut seat 428 has reached the predetermined position, the sensor 429 transmits a signal to the central control mechanism, and the central control mechanism controls the drive motor 422 to stop working.

[0069] Please see Figure 5 As can be seen, the first folding component 450 includes:

[0070] The seventh cylinder 451 is fixed to the bottom plate 440 by a mounting bracket;

[0071] The folding knife pull block 452 is linked to the seventh air cylinder 451, which is used to drive the folding knife pull block 452 to move back and forth.

[0072] The first slider 453 is fixed on the folding knife pull block 452 and is slidably mounted above the bottom plate 440;

[0073] The lower plate 454 is fixed on the first slider 453 and extends below the lower plate 440;

[0074] The first folding blade 455 is fixed to the lower end of the lower connecting plate 454.

[0075] The second folding component 460 includes:

[0076] The eighth cylinder 461 is fixed to the bottom plate 440 by a mounting bracket;

[0077] The second slider 462 is linked to the eighth air cylinder 461 and is slidably mounted on the bottom plate 440.

[0078] The ninth cylinder 464 is fixed on the second slider 462. The ninth cylinder 464 is used to drive the fourth lifting plate 463 to rise and fall.

[0079] The second folding blade 465 is fixed to the lower end of the fourth lifting plate 463.

[0080] 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 motor driving device 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 seventh 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 ninth 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 eighth cylinders 461 operate and drive the two second sliders 462 to move away from each other. Since the ninth cylinder 464 is fixed on the second sliders 462, the fourth lifting plate 463 is linked and installed on the ninth 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.

[0081] 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.

[0082] For ease of understanding, although I have already disclosed the working principles of the folding mechanism 400, positioning mechanism, gantry frame, and translation frame 600 in my utility model patent application (application number 202423009397.9) entitled "A Compact Pocket Processing Mechanism," I will here explain the working principle of the pocket processing mechanism again with reference to the accompanying drawings:

[0083] The pocket processing mechanism includes a gantry extending in the left-right direction. A first drive device is provided on the gantry for driving a translation frame 600 to translate in the left-right direction. The translation frame 600 is provided with a second drive device and a third drive device. A material fixing mechanism 300 is mounted on the translation frame 600 via a first sliding frame 310. The second drive device is used to drive the first sliding frame 310 to translate in the front-back direction. A bag folding mechanism 400 is mounted on the translation frame 600 via a second sliding frame 410. The bag folding mechanism 400 is held above the material fixing mechanism 300. The third drive device is used to drive the second sliding frame 410 to translate in the front-back direction.

[0084] Please see Figure 7 , Figure 8 and Figure 10 As 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.

[0085] 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:

[0086] The first lifting plate 330 is slidably mounted on the first mounting plate 311 in a vertical direction;

[0087] 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.

[0088] 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.

[0089] 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.

[0090] Then, please see Figures 10-15 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.

[0091] Here, the first pressing assembly includes:

[0092] The second cylinder 352 is fixed on the first lifting plate 330;

[0093] 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.

[0094] Connecting plate 353 is fixed on second lifting plate 351;

[0095] The large pressure frame 354 is fixed on the connecting plate 353;

[0096] 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).

[0097] 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.

[0098] The second pressing assembly 360 includes:

[0099] Fixed bracket 361 is fixed above connecting plate 353;

[0100] The connecting block 363 is slidably mounted vertically on the fixed bracket 361;

[0101] The third cylinder 362 is mounted on the fixed bracket 361 and is used to drive the connecting block 363 to rise and fall.

[0102] The rear pressure strip 364 is fixed on the connecting block 363.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] The third pressing assembly 380 includes:

[0107] The sixth cylinder 381 is fixed on the fixed plate 340;

[0108] 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.

[0109] 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.

[0110] Then, please see Figure 10 As can be seen, in this embodiment, the feed inlet adjusting component 370 includes:

[0111] 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.

[0112] 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.

[0113] The front material frame 373 and the rear material frame 376 work together to form the material outlet 377.

[0114] 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.

[0115] Then, please see Figure 4 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.

[0116] Next, please refer to Figure 8 and Figure 12As 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.

[0117] 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.

[0118] Then, please see Figure 6 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.

[0119] Note that because the motor drive device 420 is used to control the raising and lowering of the first folding blade 455 and the second folding blade 465, the control precision is higher and fine adjustments can be made. When the first folding blade 455 and the second folding blade 465 are folding the processing edge of the pocket fabric, the drive motor 422 controls the first folding blade 455 and the second folding blade 465 to descend slightly to ensure that the folded edge on the pocket fabric is pressed tightly. When the lower pressure plate 382 of the positioning mechanism presses the folded edge upward, the drive motor 422 again controls the first folding blade 455 and the second folding blade 465 to descend slightly, so that the first folding blade 455 and the second folding blade 465 do not come into close contact with the folded edge. During the upward retraction of the first folding blade 455 and the second folding blade 465, neither the first folding blade 455 nor the second folding blade 465 will pull the folded edge out.
