[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application's specification are for illustrative purposes only and do not represent the only possible implementation.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level (or in a usage state, or from a certain viewpoint in the drawing) than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level (or in a usage state, or from a certain viewpoint in the drawing) than the second feature.

[0036] Unless otherwise defined, all technical and scientific terms used in this 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 this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0037] In related technologies, the die of a bag-applying machine interacts with the bag-shaped plate through its die wall to apply pressure to the bag-shaped fabric. Then, a folding knife folds the edges of the bag-shaped fabric. When the bag size changes, the die and folding knife need to be replaced, which affects the work efficiency.

[0038] Referring to Figures 1 to 3, this application provides a bag-appliing machine mold scaling mechanism 1, including a base plate 100. The base plate 100 can serve as a mounting platform for other components. The base plate 100 has opposing top and bottom sides, and the die 200 and the folding knife 310 are located on the bottom side of the base plate.

[0039] The substrate 100 also has opposing front and rear sides, with a first upright plate 140 for mounting anti-angle related components and a second upright plate 150 for connecting other power equipment fixed on the rear side.

[0040] The die 200 has a die wall that matches the preset bag shape. As one of the improvements in this application, the die wall adopts a split structure, including multiple interconnected unit walls 210. The relative positions of each unit wall 210 can be changed as needed to adapt to different bag sizes. For easy adjustment, each unit wall 210 is slidably mounted on the bottom side of the substrate 100. That is, when adjustment is needed, it can slide relative to the substrate 100 to change its position, and maintain its position after adjustment.

[0041] The concave wall is generally U-shaped, with opposite open and closed sides. The open side corresponds to the bag opening and the closed side corresponds to the bag bottom. In this embodiment, the unit wall 210 includes six pieces, including two bag bottom unit walls arranged in the center and four side unit walls arranged in pairs on the sides.

[0042] In the bag-sealing machine, the folding device 300 includes folding blades 310 and folding blade driving mechanisms 320 linked to the folding blades 310. Multiple folding blades 310 are present, and multiple sets of folding blade driving mechanisms 320 are correspondingly configured to drive the corresponding folding blades 310 to fold the bag-shaped fabric. In this embodiment, multiple sets of folding blade driving mechanisms 320 are respectively driven by corresponding unit walls 210. When the position of the unit wall 210 relative to the base plate 100 is adjusted, the corresponding folding blade driving mechanism 320 is also adjusted synchronously, simplifying the position adjustment process of the folding blades 310 and allowing them to adapt to different bag sizes. For example, the folding knife drive mechanism 320 can be a cylinder. The folding knife 310 is linked with the piston rod of the cylinder. Relative to the base plate 100, the folding knife 310 has an initial position and a working position after movement. Based on this, the working direction of the folding knife 310 is determined. When cooperating with the bag-shaped plate, the folding knife 310 is relatively far away from the bag-shaped plate in the initial position, and relatively close to the bag-shaped plate in the working position, squeezing and folding the bag-shaped fabric. The folding knife drive mechanism 320 accordingly drives the folding knife 310 to switch between the initial position and the working position.

[0043] In one embodiment, to facilitate the installation of the unit wall 210 and guide its movement, the bag-applying machine mold scaling mechanism 1 further includes an adjusting seat 230. Multiple adjusting seats 230 are connected to the base plate 100 in adjustable positions. Each unit wall 210 is fixed to its corresponding adjusting seat 230. The adjusting seat 230 can be directly slidably installed onto the base plate 100. A guide seat 110 can also be fixed to the bottom side of the base plate 100. A track 240 is slidably installed on the guide seat 110. The top of the adjusting seat 230 is fixed to the track 240, and the track 240 slides into contact with the guide seat 110. The guide seat 110 supports and guides the adjusting seat 230, while the track 240 facilitates the installation and removal of the adjusting seat 230, providing flexible assembly angles and methods. Of course, the guide seat 110 and track 240 are relative terms, and vice versa. This naming convention is merely for ease of reading and does not strictly limit the interchangeability of their positions.

[0044] Referring to Figures 4 to 7, in one embodiment, a die drive mechanism 400 capable of adjusting each unit wall 210 in conjunction with the die drive mechanism 400 is further configured. The die drive mechanism 400 can be manually driven or synchronously linked to each unit wall 210 through an automatically controlled power source. The die drive mechanism 400 includes a torsion shaft 410, and each unit wall 210 is linked to the torsion shaft via a corresponding adjustment seat 230. The torsion shaft 410 is mounted on the substrate 100 and its axis is perpendicular to the substrate 100. The torsion shaft 410 itself can be manually driven and / or equipped with a power source. When manually driven, an operating handle for easy holding or docking of auxiliary tools can be connected to the top of the torsion shaft 410. When equipped with a power source, a motor 440 or similar method can be used to achieve automatic control.

[0045] For example, a bracket 130 is fixed on the base plate 100. The bottom of the bracket 130 is fixed to the base plate 100 by multiple support columns. The top of the torsion shaft 410 is rotatably engaged with the bracket 130, and the bottom of the torsion shaft 410 is rotatably engaged with the base plate 100. The shaft of the motor 440 (which may include a reduction mechanism) is arranged horizontally, which can reduce the height of the equipment. The motor then transmits power to the vertically positioned torsion shaft 410 through a universal joint 450. Using a universal joint 450 for transmission not only simplifies the structure but also compensates for machining and assembly errors to a certain extent.

[0046] In one embodiment, in order to lock the position after adjusting the unit wall 210, a corner limiting mechanism that cooperates with each other can be provided between the torsion shaft 410 and the bracket 130 to maintain the current position of the torsion shaft 410. In addition, the motor 440 can be self-locked to maintain the current position of the torsion shaft 410.

[0047] The torsion shaft 410 can simultaneously drive all controlled unit walls 210 through a linkage assembly. This design is simple, easy to operate, and improves work efficiency. All controlled unit walls 210 have at least two adjustment directions, enabling interlocking of their movements. When one unit wall 210 moves independently, it can be restricted by the other unit walls 210. The torsion shaft 410 rotates around an axis perpendicular to the substrate 100. Each unit wall 210 is arranged around the axis on the outer periphery of the torsion shaft 410. During adjustment, all unit walls 210 tend to converge towards the torsion shaft 410 or diverge outwards away from it.

[0048] In one embodiment, in order to guide the movement of the adjustment seat 230, the substrate 100 provides a strip-shaped guide hole 120 for each adjustment seat 230. Of course, some adjustment seats 230 with the same adjustment direction can also share the same guide hole 120. The adjustment seat 230 is connected to a transmission member that is inserted into the corresponding guide hole 120, and is connected to the torsion shaft 410 through the transmission member.

[0049] For example, the first transmission component 232 is directly fixed on the adjusting seat 230, and the second transmission component 241 can also be set through the track 240 on the adjusting seat 230. When the transmission component needs to be adjusted, it moves along the corresponding guide hole 120, directly or indirectly driving the adjusting seat 230. According to the adjustment direction of the unit wall 210, multiple guide holes 120 are roughly radially distributed around the torsion axis 410. As for each transmission component itself, it can be a transmission pin that is vertically fixed to the adjusting seat 230 or the track 240, and the shape is not strictly limited.

[0050] In one embodiment, the linkage component includes a synchronization plate 420 and a linkage plate 430. The synchronization plate 420 is fixed to the bottom of the torsion shaft 410 and is located above the substrate 100. The synchronization plate 420 has a connecting hole 422 in the middle. The bottom of the torsion shaft 410 is fixedly inserted into the connecting hole 422. The bottom of the torsion shaft 410 can also extend further downward through the synchronization plate 420, and the extended part is rotatably mounted to the substrate 100.

[0051] Two strip-shaped synchronization holes 421 are formed on the synchronization plate 420, and the extension direction of each synchronization hole 421 is oblique to the radial direction of the torsion shaft 410. There are two connecting plates 430, which are arranged on two opposite sides of the radial direction of the torsion shaft 410, and the synchronization plate 420 is stacked on the two connecting plates 430. A third transmission component 431 is fixed on each connecting plate 430. The third transmission component 431 can be a transmission pin or the like that that is vertically fixed to the connecting plate 430. The third transmission component 431 extends into the corresponding synchronization hole 421.

[0052] The synchronous plate 420 rotates with the torsion shaft 410, and then drives each connecting plate 430 through the synchronous hole 421 and the third transmission member 431. In order to limit the movement direction of the connecting plates 430, each connecting plate 430 is provided with a strip-shaped guide hole 433. A guide member (not shown in the figure, such as a guide pin) extending into the guide hole 433 is fixed on the base plate 100. As can be seen in the figure, all the guide holes 433 have the same extension direction, for example, they all extend in the front-back direction, that is, the two connecting plates 430 can move synchronously in opposite directions, and synchronously move closer to or away from the torsion shaft 410.

[0053] In order to drive each adjustment seat 230, each linkage plate 430 is provided with multiple drive holes 432, and the first transmission member 232 and the second transmission member 241 extend into the corresponding drive holes 432.

[0054] Referring to Figures 7 to 10, since the movement directions of each unit wall 210 and the connecting plate 430 may not be consistent during adjustment, in one embodiment, for the unit wall 210 that moves in the same direction as the connecting plate 430, a track 240 is fixed on the adjustment seat 230 to which it is fixed, and a second transmission member 241 is fixed on the track 240. The second transmission member 241 is fixed to the drive hole 432 where it is located, that is, it is fixed and directly moves with the connecting plate 430.

[0055] Referring to Figures 11 and 12, in one embodiment, for the unit wall 210 whose movement direction is inconsistent with that of the connecting plate 430, the drive hole 432 is a strip-shaped hole and obliquely intersects with the corresponding guide hole 120. The first transmission member 232 is fixed to the adjusting seat 230 and extends into the drive hole 432 with its top movable, so as to release the component force in the unexpected direction and ensure that the adjusting seat 230 moves smoothly along the guide hole 120. The transmission members in the above embodiments can be respectively fitted with bearings, and cooperate with the guide hole 120, the synchronization hole 421 or the drive hole 432 through the corresponding bearings to reduce the resistance during movement and reduce component wear.

[0056] In the embodiments described above, the unit wall 210 adopts a modular design, which can flexibly adapt to the bag size. In some cases, the shape of a certain unit wall 210 itself needs to be adjusted, and the unit wall 210 needs to be replaced. To facilitate disassembly and maintenance, some implementation methods are described below.

[0057] Referring to Figures 8 and 9, in one embodiment, the adjustment seat 230 and the unit wall 210 are detachably connected by magnetic attraction.

[0058] The adjustment seat 230 has a magnetic attraction member 231 embedded inside or at the bottom, and the magnetic attraction member 231 magnetically attracts the unit wall 210. For example, the bottom of the adjustment seat 230 has multiple slots arranged at intervals, and the attraction member 231 is made up of multiple pieces and fixed in the corresponding slots, which also makes the bottom of the adjustment seat 230 relatively flat.

[0059] The unit wall 210 can be directly magnetically attracted to the bottom of the adjusting seat 230. A connecting plate 220 can also be fixed to the top surface of the unit wall 210, and the connecting plate 220 is attached to the bottom of the adjusting seat 230. When disassembly is required, the connecting plate 220 and the adjusting seat 230 can be separated simply by overcoming the magnetic attraction, thus separating the unit wall 210. A complementary interlocking structure can also be provided between the adjusting seat 230 and the connecting plate 220 to further prevent misalignment and improve assembly accuracy.

[0060] Referring to Figures 9-12, the folding knife device 300 is configured with multiple sets, each set including a folding knife 310 and a corresponding folding knife drive mechanism 320. Each set corresponds to one unit wall 210, so that the folding knife drive mechanism 320 and the corresponding folding knife 310 move together with the corresponding unit wall 210. In use, the folding knife 310 moves relative to each unit wall 210 to switch between the initial position and the working position.

[0061] The folding knife drive mechanism 320 can be a motor or a cylinder. In one embodiment, taking a cylinder as an example, the cylinder body is directly or indirectly fixed to the adjusting seat 230. In this embodiment, a cylinder support 330 is integrally or separately fixed on the adjusting seat 230. The cylinder body is fixedly connected to the cylinder support 330. The piston rod 321 of the cylinder is connected to a movable support 340. The folding knife 310 is detachably installed on the movable support 340.

[0062] Since the two unit walls 210 in Figure 9 are adjusted synchronously, they can share the adjustment seat 230. However, the two corresponding folding blades 310 move independently. Therefore, two sets of folding blade drive mechanisms 320 are installed on the same cylinder support 330, and each cylinder drives the corresponding folding blade 310.

[0063] In one embodiment, the detachable method of the folding knife 310 can be achieved by using a locking cylinder 350, which facilitates quick assembly. For example, the folding knife 310 is connected to the movable support 340 through the knife holder assembly 360, wherein the movable support 340 is fixed with a connecting seat 341, and the locking cylinder 350 is installed on the connecting seat 341. The connecting seat 341 is provided with a connecting port, and at least a part of the knife holder assembly 360 is movably inserted into the connecting port and positioned and quickly disassembled by the action of the locking cylinder 350.

[0064] In one embodiment, the blade holder assembly 360 specifically includes a locking block 361 inserted into the mating port, and an adjusting bracket connected to the locking block 361, with the folding blade 310 fixedly mounted on the adjusting bracket. The cylinder is located above the base plate 100, and the folding blade 310 gradually descends in height via the movable support 340 and the blade holder assembly 360 until it is positioned below the base plate 100.

[0065] The adjusting frame has a first hole 363. A portion of the bottom of the locking block 361 is exposed at the bottom of the joint. This portion has a slot corresponding to the position of the first hole 363 or multiple positioning holes spaced apart. The adjusting frame is fixed to the bottom of the locking block 361 by fasteners (not shown in the figure), allowing the folding blade 310 to be adjusted in stages or continuously relative to the movable support 340 along the working direction. When the synchronous adjustment of the folding blade 310 and the unit wall 210 cannot meet the requirements, the position of the folding blade 310 can be adjusted independently, further improving the versatility of the mold. It can be understood that "stages" refers to gradually changing the gear position. In this embodiment, it means that the movable support 340 can gradually change the adjustment position.

[0066] The adjustment frame includes a first adjustment frame 362 and a second adjustment frame 365 that are adjustable in height. The first adjustment frame 362 is fixed to the bottom of the locking block 361. A first hole 363 is formed in the first adjustment frame 362. The first adjustment frame 362 has a downwardly extending bent portion, and the bent portion also has a second hole 364 extending in height. The second adjustment frame 365 has a horizontally extending portion for fixing the folding blade 310, and an upwardly extending bent portion that is abutted against the portion where the second hole 364 is located. The first adjustment frame 362 and the second adjustment frame 365 are fixed by fasteners (not shown in the figure), and the relative height of the two can be changed so that the overall height of the folding blade 310 relative to the substrate 100 is adjustable. The adjacent folding blades 310 can be aligned with each other in height (edges are adjacent to each other) or staggered and overlapped by adjusting the height direction (edges can be staggered).

[0067] Based on the above, and referring to Figures 1 and 13, this application also provides a bag-applying machine 1000, including the adjustable bag-applying machine mold scaling mechanism 1 described above. The structure of other parts of the bag-applying machine 1000 can be implemented in conjunction with related technologies.

[0068] In the adjustable bag-appliing machine mold scaling mechanism 1 of this application, the concave mold can be quickly adjusted to adapt to different bag shapes and sizes, which can reduce the manufacturing and debugging work of the fixtures and further reduce costs.

[0069] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0070] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
