The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0046] In the related art, the concave die of the bag attaching machine cooperates with the bag-shaped plate through the concave die wall to form the bag-shaped cloth, and then the edge of the bag-shaped cloth is folded by the folding knife. When the size of the bag-shaped cloth changes, the concave die needs to be replaced, which affects the work efficiency.

[0047] Referring to FIG. 1, an embodiment of the present application provides a concave die automatic scaling mechanism for a bag attaching machine, which includes a base plate 100 that can serve as a mounting platform for other components. The base plate 100 has opposite top and bottom sides. A concave die 200 and a folding knife assembly 300 are located on the bottom side of the base plate. An elevated bracket 130 is fixed above the base plate 100. A first driving mechanism 400 is mounted on the base plate 100 and the bracket 130 to adjust the position of the concave die 200.

[0048] Referring to FIGS. 2 and 3, the concave die 200 in the embodiment has a concave die wall that matches a predetermined bag shape. The concave die wall adopts a split structure and includes a plurality of unit walls 210, such as 2-8 unit walls. The relative positions between the unit walls 210 can be changed as needed to adapt to different bag sizes. For ease of adjustment, the unit walls 210 are slidingly positioned on the bottom side of the base plate 100, i.e., they can slide relative to the base plate 100 to change positions when adjustment is needed. After adjustment is completed, the positions are locked.

[0049] The unit wall 210 is block-shaped, and has a top portion facing the substrate 100, and an opposite bottom portion, the unit wall 210 has an inner side facing one side of the bag-shaped substrate, and has a protruding edge 2101 on the top portion of the unit wall 210, the protruding edge 2101 is arranged on the top side of the bag-shaped substrate during operation, and a step structure 21011 is arranged below the protruding edge 2101, the step structure 21011 has a side wall 2102 facing the bag-shaped substrate, and the side wall 2102 is matched with the edge of the bag-shaped substrate during operation to be used for bagging the cloth.

[0050] The die wall is generally U-shaped as a whole, and has opposite opening sides and closed sides, the opening sides correspond to the bag opening portion, and the closed sides correspond to the bag bottom portion, the unit wall 210 in the embodiment includes five blocks, which are a bag bottom unit wall in the middle, two bottom corner unit walls adjacent to the two sides of the bag bottom unit wall, and two side edge unit walls on the two sides of the opening,

[0051] The first driving mechanism 400 cooperates with the improved transmission mechanism by using the same power device (for example, the motor 440 below), and simultaneously drives all the controlled unit walls 210, and all the controlled unit walls 210 have different adjustment directions, that is, at least two adjustment directions, in the embodiment, the movement directions of all the controlled unit walls 210 are different during adjustment, and generally have the trend of gathering or diverging outward.

[0052] For the adjustment of each unit wall 210, a conventional power mechanism and a position locking mechanism can be respectively arranged, in order to further improve the efficiency, the same first driving mechanism 400 is used in the embodiment, the first driving mechanism 400 is in transmission connection with each unit wall 210, and drives each unit wall 210 to change the relative position. The structure is simplified and the cost is reduced.

[0053] In order to guide the movement of the unit wall 210, each unit wall 210 is fixed to the corresponding sliding seat 220, in some embodiments, the fixing mode adopts a convenient dismounting mode, for example, magnetic attraction cooperation, sliding positioning cooperation, fastener cooperation and the like. The bottom side of the substrate 100 is fixed with a guide seat 110, the sliding seat 220 is in sliding cooperation with the guide seat 110, for example, the top portion of the sliding seat 220 can be fixed with a track 222, and the track 222 is in sliding cooperation with the guide seat 110.

[0054] In order to implement driving, in one embodiment, the substrate 100 is provided with a strip-shaped guide hole 120 corresponding to each sliding seat 220, the first transmission member 221 is connected to the sliding seat 220 and is arranged in the corresponding guide hole 120, the first transmission member 221 and the sliding seat 220 are fixed to each other, and need to be adjusted along the corresponding guide hole 120, a plurality of guide holes 120 are generally radially distributed, and the first transmission member 221 can be a transmission pin fixed vertically on the sliding seat 220 or the like.

[0055] In one embodiment, the first driving mechanism 400 includes a motor 440 as a power device, which has the advantages of easy control, high adjustment precision, etc. The motor 440 can also cooperate with a sensor to detect the position signal of the moving part, perform information feedback, and be controlled accordingly. After adjustment is completed, the motor 440 is self-locked to maintain the position of the unit wall 210. The transmission cooperation between the motor 440 and the first transmission member 221 can adopt different forms such as cam, connecting rod, gear, etc.

[0056] In one embodiment, the motor 440 is installed on the bracket 130, and the motor shaft of the motor 440 is connected to the torsion shaft 410 through a universal joint 450. The torsion shaft 410 is arranged vertically, i.e., perpendicular to the base plate 100, and the motor 440 is arranged horizontally to reduce the space occupation. The universal joint 450 can effectively transmit and bear a large torque.

[0057] The top of the torsion shaft 410 is rotatably connected to the bracket 130, and the bottom of the torsion shaft 410 is rotatably connected to the base plate 100. The bottom of the torsion shaft 410 is also fixed with a synchronization plate 420 above the base plate 100. The synchronization plate 420 is provided with two strip-shaped synchronization holes 421. The extension direction of each synchronization hole 421 is obliquely intersected with the radial direction of the torsion shaft 410.

[0058] In one embodiment, in order to link multiple unit walls 210, a linkage plate 430 is also provided. The linkage plate 430 has two plates arranged on two opposite sides of the radial direction of the torsion shaft 410, and the synchronization plate 420 is stacked on the two linkage plates 430. Each linkage plate 430 is fixed with a second transmission member 431, which can be a transmission pin fixed vertically on the linkage plate 430. The second transmission member 431 extends into the corresponding synchronization hole 421.

[0059] The movement mode of the synchronization plate 420 is to rotate with the torsion shaft 410, and then drive each linkage plate 430 through the synchronization hole 421 and the second transmission member 431. In order to limit the movement direction of the linkage plate 430, a strip-shaped second guide hole 433 is formed on each linkage plate 430, and a guide pin 140 fixed on the base plate 100 extends into the second guide hole 433. As shown in the figure, all the second guide holes 433 have the same extension direction, for example, all extend in the front-back direction (corresponding to the up-down direction in FIG. 2). The front-back direction is defined as X, i.e., the two linkage plates 430 can synchronously move in opposite directions and synchronously move close to or away from the torsion shaft 410.

[0060] Each linkage plate 430 is provided with a plurality of drive holes 432, and the first transmission member 221 extends into the corresponding drive hole 432. However, it is not strictly required that all the first transmission members 221 adopt this transmission mode. It can be understood that at least one first transmission member 221 adopts this transmission mode.

[0061] Since the movement direction of each unit wall 210 and the linkage plate 430 may not be consistent during adjustment, in one embodiment, for the unit wall 210 with consistent movement direction, the first transmission member 221 is fixed to the driving hole 432, i.e. directly follows the linkage plate 430.

[0062] In one embodiment, for the unit wall 210 with inconsistent movement direction, the corresponding first transmission member 221 is movably inserted into the driving hole 432, at this time the driving hole 432 is a strip-shaped hole and is obliquely intersected with the corresponding guide hole 120, so as to release the component force in the unintended direction and ensure smooth movement of the first transmission member 221 along the guide hole 120.

[0063] For example, in the five unit walls 210 in FIG. 3, the bag bottom unit wall 210 and two bottom corner unit walls 210 are linked to one of the linkage plates 430, and the two side edge unit walls 210 are linked to another linkage plate 430, wherein the bag bottom unit wall 210 directly follows the linkage plate 430, and the remaining four unit walls 210 have inconsistent adjustment direction with the movement direction of the linkage plate 430.

[0064] In the above embodiments, the unit wall 210 adopts a modular design and can be flexibly adapted to the size of the bag. In some cases, the shape of a unit wall 210 itself needs to be adjusted, and then the unit wall 210 needs to be replaced. In order to facilitate disassembly and maintenance, some embodiments are provided below.

[0065] Referring to FIGS. 6 and 7, in one embodiment, the sliding seat 220 and the unit wall 210 are detachably connected by magnetic attraction. The top of the sliding seat 220 is provided with a track 222 matched with the guide seat 110. Of course, the guide seat 110 and the track 222 are relative, and vice versa, which is the same reason. Such naming is only convenient for reading and does not strictly limit whether the positions of the two are interchangeable.

[0066] The track 222 not only plays a sliding matching role, but can be further extended to assist in supporting the folding knife assembly 300. Since the folding device is fixed relative to the base plate 100 (the relative position is pre-adjusted and locked) during work, and the folding knife assembly 300 needs to reciprocate to act on the bag-shaped fabric, the sliding matching between the folding knife assembly 300 and the track 222 is adopted to avoid hindering the movement of the folding knife assembly 300.

[0067] The inside or bottom of the sliding seat 220 is embedded with a magnetic attraction member 223, and the unit wall 210 is magnetically attracted to the sliding seat 220 through the magnetic attraction member 223. The top surface of the unit wall 210 can be fixed with a connecting plate 211, and the bottom of the sliding seat 220 is attached to the connecting plate 211. When disassembly is needed, the unit wall 210 can be separated by overcoming the magnetic attraction force. The sliding seat 220 and the connecting plate 211 can also be provided with complementary clamping structures to further avoid dislocation between each other and improve assembly accuracy.

[0068] In one embodiment, the folding knife assembly 300 comprises a folding knife 310 and a second driving mechanism 320 connected with the folding knife 310, the second driving mechanism 320 can be a push-pull cylinder 322 fixed on the base plate 100, the folding knife 310 is connected with the piston rod of the push-pull cylinder 322, the folding knife 310 has an initial position and a working position after movement, when the folding device clamps the bag-shaped cloth with the bag-shaped plate, the folding knife 310 is relatively far away from the bag-shaped plate in the initial position, and is relatively close to the bag-shaped plate in the working position to fold the bag-shaped cloth, the second driving mechanism 320 correspondingly drives the folding knife 310 to switch between the initial position and the working position.

[0069] The folding knife assembly 300 is configured with multiple sets, and for the whole bagging machine, the folding knife assembly 300 in this embodiment or shown in the figure is not strictly limited to all folding knife assemblies 300 in the bagging machine, but at least includes two or more sets.

[0070] Each set of folding knife assembly 300 corresponds to one unit wall 210, since the folding knife 310 moves relative to each unit wall 210 during work, in order to adjust the unit wall 210 while adjusting the folding knife 310 and allowing the relative movement of the unit wall 210 and the folding knife 310 in this embodiment, the connection between the unit wall 210 and the folding knife 310 is improved, that is, a resettable movable connection is adopted. Specifically, the tail of the folding knife 310 is fixed with a knife seat 330, the unit wall 210 is fixed with a guide rod 224, the knife seat 330 is provided with a first guide hole 331 for the guide rod 224 to slide through, the end of the guide rod 224 protruding from the knife seat 330 is provided with a limiting head 225, so that the folding knife 310 can slide relative to the unit wall 210, on this basis, a reset member 350 is arranged between the unit wall 210 and the knife seat 330, for example, the reset member 350 is a spiral compression spring sleeved on the guide rod 224, after the movement of the folding knife 310, the relative position between the unit wall 210 and the folding knife 310 can be maintained under the action of the reset member 350, when the folding knife 310 is disconnected with the second driving mechanism 320, the position can be adjusted synchronously with the unit wall 210, and after the adjustment is completed, the connection with the second driving mechanism 320 is restored.

[0071] The folding knife 310 and the second driving mechanism 320 are connected through a locking mechanism 500 to realize position-adjustable transmission, the locking mechanism 500 has a locking state of keeping the second driving mechanism 320 connected with the folding knife 310, and a release state of disconnecting, in order to adapt to the follow-up adjustment of the folding knife 310 and the unit wall 210, the locking mechanism 500 allows the folding knife 310 to change the relative position with the second driving mechanism 320 in the release state.

[0072] The power of the second driving mechanism 320 can be in the form of an electric motor or a pneumatic cylinder, and a corresponding transmission mechanism is provided. In order to drive the folding knife 310, the second driving mechanism 320 as a whole has an output member 321 at the downstream side and movable in transmission sequence. The folding knife 310 is fixed with a handle 340, and the locking mechanism 500 can be connected between the handle 340 and the output member 321. The position-adjustable transmission connection mode can be in the form of a locking cylinder, a manual latch, engagement, tight fit, magnetic attraction, etc.

[0073] Since the adjustment of the unit wall 210 and the folding knife 310 is not in a step-by-step manner, it can be only fine adjustment or stepless adjustment. In order to realize automatic control, in some embodiments, an automatic locking member 520 is provided in the position-adjustable transmission connection, that is, the switching between the locked state and the released state can be realized by automatic control, and it is also suitable for stepless adjustment. The automatic locking member 520 can lock or release the handle 340 and allow the handle 340 to slide for adjustment, for example, by using a locking cylinder.

[0074] In order to facilitate disassembly and maintain the relative position of the folding knife 310 and the second driving mechanism 320 before and after disassembly, a manual locking member 530 can also be provided in the locking mechanism 500. When in use, the manual locking member 530 remains connected, and when disassembly is required, the connection is released to separate. In some embodiments, the manual locking member 530 adopts a structure that can be quickly positioned and disassembled, such as a positioning pin or a clamping mode, etc.

[0075] In combination with FIGS. 8 and 9, in one embodiment, in order to realize the above connection mode and bear related components, the locking mechanism 500 includes a combination seat 510, an automatic locking member 520 and a manual locking member 530. One of the automatic locking member 520 and the manual locking member 530 acts between the combination seat 510 and the second driving mechanism 320, and the other acts between the combination seat 510 and the folding knife 310.

[0076] In one embodiment, the second driving mechanism 320 is a push-pull cylinder 322, the output member 321 is a connecting seat fixed to the piston rod of the push-pull cylinder 322, and the manual locking member 530 acts between the connecting seat and the combination seat 510. For example, the connecting seat is provided with a strip-shaped hole, and the manual locking member 530 is a locking bolt provided on the combination seat 510 and passing through the adjusting hole. For another example, a pin hole is provided between the connecting seat and the combination seat 510, and the manual locking member 530 is a positioning pin inserted into the corresponding pin hole. When disassembled, the combination seat 510 and the second driving mechanism 320 can be quickly separated by the manual locking member 530, and the unit wall 210 and the corresponding folding knife assembly 300 can be quickly removed in combination with the magnetic attraction mode of the unit wall 210 and the sliding seat 220.

[0077] In one embodiment, the bottom of the connecting seat 510 is provided with a first limiting hole 512, the handle 340 is inserted into the first limiting hole 512, and the automatic locking member 520 is a locking cylinder installed in the connecting seat 510. The piston rod of the locking cylinder is provided with a limiting head 513 which acts on the handle 340. In order to adapt to the adjustment and disassembly of the folding knife 310, the handle 340 is provided with a strip hole 341 which is open at one end. The piston cylinder of the locking cylinder passes through the strip hole, and the limiting head 513 is located at the end of the piston cylinder which passes through the strip hole 341. When adjustment is needed, the locking cylinder is released, and the handle 340 can be moved to any position within the stroke range relative to the locking cylinder. After the adjustment of the unit wall 210 and the folding knife 310 by the first driving mechanism 400, the locking cylinder is locked again.

[0078] The adjustment direction of the unit wall 210 is limited by the guide hole 120, and the arrangement direction of the guide seat 110 and the track 222 is corresponding thereto. For example, the extension direction of the guide hole 120 is the first direction, and the folding knife 310 moves along the second direction when it works. If the first direction is parallel to the second direction (such as the embodiment in FIG. 6), for example, the bottom unit wall and the two bottom corner unit walls, when the unit wall is adjusted, the locking mechanism 500 releases the locking of the handle 340 of the folding knife 310, and then adjusts the folding knife 310, and there is no motion direction interference.

[0079] In some cases, for example, in the two side edge unit walls, the first direction and the second direction are inclined to each other. When the unit wall 210 is adjusted along the first direction, the folding knife 310 cannot directly follow the adjustment because it moves along the second direction relative to the second driving mechanism, and there is motion direction interference.

[0080] Referring to FIGS. 10 and 11, in one embodiment, a sliding joint along the third direction is arranged between the locking mechanism 500 and the second driving mechanism, or in the locking mechanism 500. The sliding joint can be a sliding fit split structure of the connecting seat 510 itself, one part of which is connected to the second driving mechanism 320, and the other part is connected to the folding knife 310.

[0081] The sliding joint in FIGS. 10 and 11 includes a sliding seat 323 and a sliding rail 324 which cooperate with each other.
