[0072] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. The use of the terms "and / or" includes a set of one or more associated listed items.

[0073] Reference is made to Figures 1 to 6In an embodiment of the present application, a bag folding device for a bagging machine is provided, which comprises a plurality of folding assembly sets 300 arranged around a bag-shaped area 600 and adjustable in position, the bag-shaped area 600 corresponds to a preset bag shape, although the bag shape changes and the bag-shaped area 600 scales accordingly, it has a relative bag opening side 610 and a bag bottom side 620 as a whole, which can be understood as a specific part of the bag-shaped area 600 itself, and as a general direction and area for other components. A center line 630 extends between the bag opening side 610 and the bag bottom side 620, which is generally the axis of symmetry of the bag-shaped area 600.

[0074] The folding assembly set 300 adjustable in position can adapt to changes in the size of the bag shape, for example, the folding assembly set 300 comprises:

[0075] Two first folding assembly sets 310 are located on the bag opening side 610 and arranged on both sides of the center line 630, respectively, and the position adjustment direction of each first folding assembly set 310 is perpendicular to the center line 630.

[0076] A plurality of second folding assembly sets 320 are arranged around the bag-shaped area 600 from the bag opening side 610 to the bag bottom side 620, and the position adjustment direction of each second folding assembly set 320 is arranged parallel or inclined to the center line 630.

[0077] In the present application, each folding assembly set 300 and the unit module hereinafter are symmetrical about the center line 630 in the overall layout without special instructions, but the symmetry of the specific structure is not strictly limited based on this, especially not strictly limited to mirror synchronization during their respective movement or position adjustment.

[0078] The first folding assembly set 310 comprises a first folding cylinder 312 and a first folding blade 313 driven by the first folding cylinder 312, for example, the first folding blade 313 can be connected to the piston rod of the first folding cylinder 312 through a first connecting seat 314 and make linear reciprocating motion.

[0079] Similarly, the second folding assembly set 320 comprises a second folding cylinder 321 and a second folding blade 326 driven by the second folding cylinder 321, for example, the second folding blade 326 can be connected to the piston rod of the second folding cylinder 321 through a second connecting seat 325 and make linear reciprocating motion.

[0080] Referring to Figure 2 The plurality of second folding assembly sets 320 comprise a side edge folding assembly set 3201 and a bag bottom folding assembly set 3203 arranged in sequence from the bag opening side 610 to the bag bottom side 620, wherein the position adjustment direction of the side edge folding assembly set 3201 is arranged inclined to the center line 630, for example, having an included angle of 30-60 degrees, and the position adjustment direction of the bag bottom folding assembly set 3203 is parallel to the center line 630.

[0081] In order to meet the special folding requirements of the bag mouth part, the cutter assembly 300 can further comprise a bag mouth cutter assembly 330, which is two sets and the relative positions are adjustable to adapt to the size change of the bag shape. The overall cutter assembly 300 is on the side away from the second cutter assembly 320 of the first cutter assembly 310. The bag mouth cutter assembly 330 adopts a rotary air cylinder, i.e. a bag mouth cutter air cylinder 331, and drives a reciprocating swinging bag mouth cutter 332.

[0082] For example, the position in the bag shape area 600 is taken as an example, the dashed line represents the bag shape area 600, the left side of the center line 630 shows the state before the position adjustment of the first cutter 313 and the second cutter 326, and the right side of the center line 630 shows the state after the position adjustment of the first cutter 313 and the second cutter 326. Figure 4a

[0083] When the size of the bag shape changes and the layout of the cutter assembly 300 needs to be adjusted, if the first cutter 313 and the second cutter 326 move obliquely downward (one of them is taken as an example in the direction of the arrow L) and away from each other, the bag shape area 600 surrounded by the first cutter assembly 310 and the second cutter assembly 320 is enlarged and moved downward as a whole, deviating from the previous reference position. Especially when the bag mouth cutter assembly 330 is configured, since the bag mouth cutter assembly 330 generally does not move along the center line 630, the first cutter assembly 310 and the second cutter assembly 320 will be away from the bag mouth cutter assembly 330, affecting the cooperation effect of each other, which may cause poor folding effect of the bag shape cloth.

[0084] The present application divides the cutter assembly 300 into the first cutter assembly 310 moving along the vertical center line 630 and the second cutter assembly 320 moving parallel or obliquely relative to the center line 630 according to the position adjustment trend. The first cutter assembly 310 moves horizontally along the arrow W direction in the figure when adjusting the position, and the projection position on the center line 630 remains unchanged and can be used as a position reference. The overall scaling of the bag shape area 600 surrounded by the second cutter assembly 320 is relative to the movement path of the first cutter assembly 310, which also provides an initial reference for the assembly and movement control of the equipment, simplifies the design and processing process, and also ensures the coordination of the cutter assembly 300 with the surrounding matching components before and after adjustment.

[0085] In terms of providing a position reference, the first cutter assembly 310 is two sets and arranged on both sides of the center line 630, but in terms of the position adjustment trend of the cutter assembly, the first cutter assembly 310 is not strictly limited to only two sets. Although two sets are taken as an example in each figure, more can be set as needed.

[0086] ​The first folding knife assembly 310 is adjusted in position in an automatic or manual manner, and the two sets of first folding knife assemblies 310 are independently adjusted in position or are synchronously and reversely adjusted in position in linkage, wherein the linkage adjustment in position is mechanical transmission or is based on a cooperative control signal. Preferably, the two sets of first folding knife assemblies 310 are adjusted in position in linkage, and all the second folding knife assemblies 320 are adjusted in position in linkage.

[0087] In the direction of the center line 630, the folding knives of the first folding knife assembly 310 have a span M1, and the folding knives of the second folding knife assembly 320 have a total span M2. When the second folding knife assembly 320 is arranged in multiple sets in the direction of the center line 630, the total span includes the spacing between the folding knives in addition to the span of each folding knife itself. The span of each folding knife is not the boundary of the component structure and shape, and should be understood as the span of the side of the folding knife that interacts with the bag-shaped cloth, which is substantially parallel to the edge of the corresponding part of the bag-shaped area 600.

[0088] The ratio of M1 to M2 is less than or equal to 30%, for example, the ratio of M1 to M2 is 10% to 25%. According to the approximate proportional relationship, the folding knives of the second folding knife assembly 320 have a larger span ratio, which is more easily adapted to the adjustment of a larger range of the bag-shaped area 600, and can more reasonably distribute the spacing of the folding knife assemblies in the direction of the center line 630.

[0089] Referring to Figure 4b The edge of the bag-shaped area 600 includes a side edge 601 and a bottom edge 602 arranged in sequence from the bag opening side 610 to the bag bottom side 620. The side edge 601 and the bottom edge 602 are mainly divided according to the included angle between the overall extension trend and the center line 630. The included angle between the side edge 601 and the center line 630 is smaller or even parallel, while the included angle between the bottom edge 602 and the center line 630 is larger, for example, greater than or equal to 45 degrees, or even perpendicular. The side edge 601 and the bottom edge 602 can be straight lines, curved lines or broken lines, which are not strictly limited.

[0090] Since the first folding knife assembly 310 serves as a reference for the bag opening side 610, it is preferred to be located only at one end of the side edge 601 away from the bottom edge 602, for example, in the direction of the center line 630, the ratio of the span M1 of the folding knives of the first folding knife assembly 310 to the span of the side edge 601 is less than or equal to 50%, and for example, 10% to 30%.

[0091] Since the folding knife assembly 300 is adjustable in position, the shape of the bag-shaped area 600 is not unique. The above proportions can be understood as the proportional relationship when the folding knife assembly 300 is adjusted to the minimum size of the bag-shaped area 600.

[0092] The above ratio can also be applied to the unit molds in other embodiments, wherein the span of the first unit mold corresponds to the span of the folding knives in the first folding knife assembly 310, the total span of the second unit mold corresponds to the total span of the folding knives in the second folding knife assembly 320, and the span of each unit mold is not the boundary of the component structure profile, and should be referred to the location of the concave mold wall matched with the bag-shaped plate.

[0093] Based on the folding knife device of the bagging machine of the present application, one embodiment further provides a bagging machine, which comprises a base plate 100, a concave mold device and a plurality of folding knife assemblies 300 mounted on the base plate 100, and the concave mold device and the plurality of folding knife assemblies 300 are matched with each other for folding the bag-shaped fabric, wherein each unit mold and each folding knife assembly 300 is positionally adjustable relative to the base plate 100. The base plate 100, as the mounting platform of other components, has opposite top and bottom sides, the concave mold device comprises a concave mold 200 for defining a bag-shaped area 600, and the concave mold 200 is located at the bottom side of the base plate 100. The concave mold 200 of the present application adopts a split structure, i.e. comprises a plurality of unit molds, each of which is slidably and positionally mounted on the base plate 100.

[0094] The concave mold 200 has a concave mold wall matched with the edge of the bag-shaped plate, and the bag-shaped area 600 can also refer to the area enclosed by the concave mold wall. The concave mold 200 can be scaled, i.e. the bag-shaped area 600 is changed, and in terms of the whole concave mold wall, it can be understood that each unit mold provides a part of the unit wall. In the present application, when the bag-shaped size is changed, the concave mold device and the plurality of folding knife assemblies 300 are adjusted accordingly, so that the bag-shaped area 600 enclosed by the concave mold device and the plurality of folding knife assemblies 300 always remains consistent.

[0095] The plurality of positionally adjustable unit molds in the present embodiment specifically comprises:

[0096] Two first unit molds 210 are located at the bag mouth side 610 and arranged on both sides of the center line 630, respectively, and the position adjustment direction of each first unit mold 210 is perpendicular to the center line 630;

[0097] A plurality of second unit molds 220 are arranged around the bag-shaped area 600 from the bag mouth side 610 to the bag bottom side 620, and the position adjustment direction of each second unit mold 220 is parallel or inclined to the center line 630.

[0098] In order to adjust each second folding knife assembly 320 and each second unit mold 220, different transmission forms such as cams, connecting rods, and gears can be used. As a preferred embodiment, the folding knife device of the bagging machine of the present application further comprises a first lead screw mechanism 400 mounted on the top side of the base plate 100, and drives each second folding knife assembly 320 and each second unit mold 220 to perform linkage position adjustment in a corresponding transmission manner, which can improve the adjustment efficiency and synchronization.

[0099] The first screw mechanism 400 comprises a first motor 410 (a reducer can be configured according to requirements), a shaft coupling 420, a first screw 430, and a nut seat 440 threadedly connected with the first screw 430. The first support 110 is fixed on the top side of the base plate 100 and can comprise a plurality of support components for supporting two ends of the first motor 410 and the first screw 430, respectively. The bottom of the nut seat 440 is fixed with a driving plate 450 which slides on the top side of the base plate 100. The driving plate 450 is linked with each second folding knife assembly 320 and each second unit mold 220. A guide structure can be arranged between the top side of the base plate 100 and the driving plate 450 to guide the smooth movement of the driving plate 450, for example, one has a guide rail and the other has a guide seat matched with the guide rail.

[0100] To assist automatic control, a first detector 460 can be arranged to sense the position of the nut seat 440, and the second folding knife assembly 320 and the second unit mold 220 are adjusted in position according to the feedback. The extension direction of the first screw 430 is consistent with the center line 630, which can save height space. In the preferred embodiment, the vertical projection position of the first screw 430 corresponds to the position of the center line 630, which is more convenient for symmetrical arrangement of the transmission mechanism.

[0101] The bottom side of the base plate 100 is slidably installed with a first adjusting seat 221 linked with the driving plate 450, and the second unit mold 220 is directly or indirectly fixed to the bottom of the first adjusting seat 221 through a connecting block 225. According to the expected position adjustment direction, a corresponding transmission mode can be adopted between the first adjusting seat 221 and the driving plate 450. Since the driving plate 450 moves along the center line 630 with the nut seat 440, and the position adjustment direction of the second unit mold 220 is arranged obliquely to the center line 630, the transmission mode adopted in this embodiment is that a first hole 101 is arranged on the base plate 100, and a second hole 451 is arranged on the driving plate 450. The first hole 101 and the second hole 451 are arranged obliquely and have an overlapping area. The second hole 451 extends substantially along the vertical direction of the center line 630, and the extension direction of the first hole 101 corresponds to the position adjustment direction of the second unit mold 220. A first transmission member 224 is fixed on the first adjusting seat 221, which can pass through the first hole 101 and the second hole 451 in sequence in an upward direction. The first adjusting seat 221 and the second unit mold 220 are driven by the first transmission member 224 through the cooperation of the first hole 101 and the second hole 451.

[0102] To guide smoothly, a guide rail 222 is arranged on the bottom of the base plate 100, and a sliding block 223 matched with the guide rail 222 is arranged on the top of the first adjusting seat 221. Of course, the guide rail 222 and the sliding block 223 can also be interchanged in position.

[0103] The second folding cylinder 321 in the bag bottom folding cylinder assembly 3203 is arranged on the top side of the base plate 100 and is mounted on the driving plate 450. The piston rod 322 of the second folding cylinder 321 is connected with a connecting seat 323 extending to the bottom side of the base plate 100. The connecting seat 323 is provided with a locking cylinder 324. The second folding cylinder 326 is detachably inserted and fixed on the connecting seat 323 through a second connecting seat 325 and is locked and positioned by the locking cylinder 324. The second connecting seat 325 can also be fixed to the connecting seat 323 by screws or other ways.

[0104] The second folding cylinder 321 in the bag bottom folding cylinder assembly 3203 is arranged on the top side of the base plate 100 and is mounted on the driving plate 450. The piston rod 322 of the second folding cylinder 321 is connected with a connecting seat 323 extending to the bottom side of the base plate 100. The connecting seat 323 is provided with a locking cylinder 324. The second folding cylinder 326 is detachably inserted and fixed on the connecting seat 323 through a second connecting seat 325 and is locked and positioned by the locking cylinder 324. The second connecting seat 325 can also be fixed to the connecting seat 323 by screws or other ways.

[0105] In order to drive the bag opening folding cylinder assembly 330, the top side of the base plate 100 is provided with a second support 120 and is correspondingly provided with a second screw rod mechanism 500. The second screw rod mechanism 500 includes a second motor 510 mounted on the second support 120, a second screw rod 520 connected with the second motor 510, and a pair of mounting seats 540 respectively threadedly matched with the second screw rod 520. The bag opening folding cylinder assembly 330 is provided with two sets of mounting seats 540 respectively arranged in the corresponding mounting seats 540. The second support 120 is further provided with a guide rod 530. Each mounting seat 540 is slidably sleeved on the guide rod 530 to limit the movement direction. In order to assist automatic control, a second detector 550 can be arranged to sense the position of the mounting seat 540, and the position adjustment of the bag opening folding cylinder assembly 330 is correspondingly fed back and controlled. Since the second screw rod 520 is used for driving, the two sets of bag opening folding cylinder assemblies 330 are reversely and synchronously moved during position adjustment, and have high adjustment accuracy.

[0106] Since the bag opening folding cylinder assembly 330, the first folding cylinder assembly 310 and the first unit mold 210 are adjacent in position and have the same position adjustment trend, any two or all of them can be independently position adjusted or position adjusted in linkage.

[0107] For example, when the bag opening folding cylinder assembly 330 and the first unit mold 210 are position adjusted in linkage, it can also be understood that the second screw rod mechanism 500 also drives the two first unit molds 210 to be position adjusted in linkage.

[0108] For example, when the bag opening folding cylinder assembly 330 and the first folding cylinder assembly 310 are position adjusted in linkage, it can also be understood that the second screw rod mechanism 500 also drives the two sets of first folding cylinder assemblies 310 to be position adjusted in linkage.

[0109] In order to cooperate with the bag-shaped plate to clamp the bag-shaped cloth, the side bottom of the base plate 100 is provided with a liftable abutment 700 (electromagnet). The bag-shaped plate can be attracted or released by electromagnetic force. The abutment 700 and the bag-shaped plate can be adjusted in height by automatic or manual way. The transmission way can adopt different ways such as gear and rack, worm and gear, bevel gear, etc.

[0110] In an embodiment of the present application, the top side of the base plate 100 is provided with a right-angle motor 710 to drive the backstop 700 to move up and down. The extension direction of the right-angle motor 710 is consistent with the center line 630 and is below the first screw rod 430, which can optimize the space arrangement and reduce the interference between each other. The output shaft of the right-angle motor 710 is arranged vertically and points to the bottom side of the base plate 100 and is correspondingly linked with the backstop 700. For example, the threaded transmission can be used to convert the rotary motion of the output shaft into the up and down movement of the backstop 700. In order to guide the backstop 700 to move up and down smoothly, the base plate 100 is provided with a guide hole, and the backstop 700 is fixed with a guide column 720 extending upward and slidingly fitted in the guide hole. In order to assist the automatic control, a third detector 730 can be provided to sense the position of the guide column 720, and the corresponding feedback and control the lifting height of the backstop 700.

[0111] The plurality of second unit molds 220 are close to each other to reduce the size of the concave mold 200 and the gap between the concave mold wall and the edge of the bag-shaped plate during position adjustment, or are away from each other to expand the concave mold 200 and increase the gap between the concave mold wall and the edge of the bag-shaped plate during position adjustment. Since the positions of the two first unit molds 210 serve as a reference, the plurality of second unit molds 220 as a whole are correspondingly away from or close to the first unit molds 210 along the center line 630.

[0112] The number of second unit molds 220 can be correspondingly set according to the overall size of the concave mold 200 and the edge shape of the bag-shaped area 600, for example, 2-6, etc. In an embodiment of the present application, a preferred manner is provided, that is, two second unit molds 220 are symmetrically arranged on both sides of the center line 630, the unit wall of each second unit mold 220 is in a broken line shape, which matches the preset bag-shaped area 600, and the position adjustment path of each second unit mold 220 gradually deviates from the center line 630 from the bag opening side 610 to the bag bottom side 620. The position adjustment path of the second unit mold 220 is arranged obliquely to the center line 630, for example, with an included angle of 30-60 degrees. Of course, in other embodiments, the second unit mold 220 located at the bag bottom side 620 can also be adjusted along the direction of the center line 630.

[0113] During position adjustment, each unit mold can be adjusted in an automatic (configured with a power source such as a motor) and / or manual manner, and each unit mold can be independently adjusted or a plurality of unit molds can be linked to adjust, for example, all first unit molds 210 are synchronously and reversely linked to adjust the position, or all second unit molds 220 are linked to adjust the position, or even all unit molds are linked to adjust the position. The linkage position adjustment does not require that each participant moves at the same time and has the same path trend.

[0114] Referring to Figure 7In order to adjust the relative position of the second folding knife 326 and the connecting seat 323 more flexibly, the connecting seat 323 is provided with a bottom-opened sliding groove, and the sliding groove is limited by the locking cylinder 324 and has a plug-in part 3231, the plug-in part 3231 is provided with a plurality of gear holes, the second connecting seat 325 is provided with a slot and a fastener is arranged between the slot and each gear hole, when the fastener is loosened, the second connecting seat 325 is allowed to slide or adjust the gear position relative to the connecting seat 323.

[0115] In the bag attaching machine, in order to better adapt to the thickness or size change of the bag-shaped cloth, simplify the structure of the equipment, the position adjustment of each folding knife assembly and the position adjustment of each unit mold are linked by mechanical structure or circuit control, for example, in one embodiment, the first folding knife assembly 310 and the first unit mold 210 have the same movement trend, so the position adjustment is linked. When the second folding knife assembly 320 and the second unit mold 220 are adjusted, they are close to or away from each other, so the position adjustment is linked. The way of linked position adjustment is mechanical transmission or action according to cooperative control signal.

[0116] Referring to Figures 8 to 10 The first unit mold 210, the bag opening folding knife assembly 330 and the first folding knife assembly 310 are arranged at the bottom of the mounting seat 540 driven by the second lead screw 520, so that the three are synchronized when adjusting the position. The bag opening folding knife cylinder 331 and the first folding knife cylinder 312 are fixed to the mounting seat 540, and the first unit mold 210 is fixed to the cylinder body of the bag opening folding knife cylinder 331. When the position adjustment is implemented, the above three are synchronized to ensure the adjustment accuracy, improve the utilization rate of the driving mechanism and the integration effect of the transmission components.

[0117] Referring to Figures 11 to 12 The main difference between the bag attaching machine provided by another embodiment of the application and the above-mentioned embodiments is that the bag bottom folding knife assembly 3203 in the second folding knife assembly 320, the second folding knife cylinder 321 is arranged at the bottom side of the base plate 100, wherein the base plate 100 is provided with an avoiding hole 103, the bottom of the driving plate 450 is fixed with a second transmission part 452, the second transmission part 452 extends to the lower side of the base plate 100 through the avoiding hole 103 and is fixed with a second adjusting seat 453, the second folding knife cylinder 321 is installed on the second adjusting seat 453, and the second folding knife 326 is connected with the piston rod of the second folding knife cylinder 321.

[0118] The bag-shaped area 600 of each embodiment is an angle shape, referring to Figures 13 to 16The main difference between the bagging machine provided by another embodiment of the present application and the above-mentioned embodiments is that the bag-shaped area 600 is truncated, and the plurality of second cutter assemblies 320 include a side edge cutter assembly 3201, a side bottom cutter assembly 3202, and a bag bottom cutter assembly 3203 arranged in sequence from the bag opening side 610 to the bag bottom side 620, and the second cutter cylinders of the three cutter assemblies 3201, 3202, and 3203 are arranged at the bottom side of the base plate 100 and mounted to the first adjusting seat 221. Therefore, the three cutter assemblies 3201, 3202, and 3203 move synchronously when the second unit mold 220 is adjusted in position.

[0119] In other embodiments, the bottom side of the base plate 100 is slidingly mounted with the first adjusting seat 221 and a third adjusting seat (not shown) linked with the driving plate 450, wherein the second unit mold 220 and the side edge cutter assembly 3201 are mounted to the first adjusting seat 221, and the side bottom cutter assembly 3202 and the bag bottom cutter assembly 3203 are mounted to the third adjusting seat, so that the position adjustment can be more flexible and controlled, and the first adjusting seat 221 and the third adjusting seat can adopt the same adjusting movement direction.

[0120] Referring to Figures 17 to 19 The main difference between the bagging machine provided by another embodiment of the present application and the above-mentioned embodiments (for example Figure 11 The corresponding embodiment) is the linkage mode of the first unit mold 210, the bag opening cutter assembly 330, and the first cutter assembly 310. In this embodiment, the base plate 100 is provided with a guide groove 102 extending along the vertical center line 630, and a base 311 is slidingly arranged in the guide groove 102. The first cutter assembly 310 is mounted to the base 311, and the base 311 and the base plate 100 are further provided with locking members (for example, bolts) for keeping the positions of each other. In this embodiment, the first cutter assembly 310 is adjusted in position by a manual mode and kept in the adjusted position by the locking members. The bag opening cutter assembly 330 and the first unit mold 210 are arranged at the bottom of the mounting seat 540, and move synchronously when the positions are adjusted.

[0121] Referring to Figures 20 to 21 The main difference between the bagging machine provided by another embodiment of the present application and the above-mentioned embodiments (for example Figure 17The main difference between the corresponding embodiment) is the linkage of the first unit die 210, the bag mouth knife assembly 330 and the first knife assembly 310, the bag mouth knife assembly 330 has been omitted from the figure, and thus the first knife assembly 310 and the first unit die 210 are both mounted on the base 311, and the locking member between the base 311 and the base plate 100 is also provided to keep the positions of each other. In this embodiment, the first knife assembly 310 and the first unit die 210 are adjusted manually, and the adjusted position is kept by the locking member. The bag mouth knife assembly 330 is arranged at the bottom of the mounting seat 540, and the position is adjusted by the driving of the second screw rod mechanism 500.

[0122] Referring to Figures 22 to 23 The bag attaching machine knife folding device of another embodiment of the present application provides a different folding knife assembly arrangement, and its driving method and other components can be combined with the above embodiments. In this embodiment, the first knife assembly 310 is two sets and arranged on both sides of the center line 630, and the second knife assembly 320 is three sets. Although the shapes of the respective knives are different, the overall arrangement is basically symmetrical about the center line 630, that is, one set is in the middle, and the other two sets are distributed on both sides.

[0123] Figure 23 The direction of each arrow in the figure shows the position adjustment trend of part of the folding knife assembly. As can be seen from the figure, the position adjustment direction of the first knife assembly 310 is perpendicular to the center line 630, the position adjustment direction of the centrally located second knife assembly 320 is parallel to the center line 630, and the position adjustment direction of the second knife assembly 320 on both sides is oblique to the center line 630. When adjustment is needed, the first knife assembly 310 is transversely moved and kept as a position reference, each set of second knife assembly 320 diverges away from each other, and all second knife assemblies 320 move away from the movement path of the first knife assembly 310 as a whole.

[0124] When the bag-shaped fabric changes in thickness during the operation of the bag attaching machine, in the standby state, the first screw rod mechanism 400 drives each second unit die 220 and each second knife assembly 320 to change the relative position, and finally realizes the overall scaling of the die 200 and the folding knife assembly 300 and the adjustment of the gap with the edge of the bag-shaped plate. At the same time, the height of the abutment 700 can also be changed by the right-angle motor 710, that is, the gap with the top surface of the bag-shaped plate is adjusted to achieve the best folding effect.

[0125] When the same version but the size changes, the first unit die 210, the bag mouth knife assembly 330 and the first knife assembly 310 can also be adjusted in the vertical center line 630 direction by the second screw rod mechanism 500 at the same time as the above operation to adapt to the new size and achieve the best folding effect.
