When a first feature is “below”, “below” or “below” a second feature, it can mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level (or in a state of use, or from a certain perspective of the drawing) than the second feature.

[0045] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0046] In the existing technology, the die of the pocket patching machine cooperates with the bag-shaped plate through its die wall to act on the bag-shaped fabric, and then folds the edge of the bag-shaped fabric through a folding knife. When the bag size changes, the die and folding knife need to be replaced, affecting the working efficiency.

[0047] See also Figures 1 to 3 In one embodiment of the present application, a pocket-sticking machine mold scaling mechanism is provided, including a base plate 100. The base plate 100 can serve as a mounting platform for other components. The base plate 100 has a top side and a bottom side relative to each other. The die 200 and the folding knife 310 are located on the bottom side of the base plate.

[0048] The base plate 100 further has a front side and a rear side opposite to each other, and a first vertical plate 140 for mounting components related to the inverted corner and a second vertical plate 150 for connecting other power equipment are fixed to the rear side.

[0049] The die 200 has a die wall that matches the preset bag shape. As one of the improvements of the present application, the die wall adopts a split structure, including a plurality of unit walls 210 that can be linked to each other. The relative positions of the unit walls 210 can be changed as needed to adapt to different bag sizes. For ease of adjustment, each unit wall 210 is slidably positioned and installed on the bottom side of the substrate 100, that is, it can slide relative to the substrate 100 to change its position when adjustment is required, and maintain the position after the adjustment is completed.

[0050] The die wall is generally U-shaped, with an open side and a closed side opposite to each other. The open side corresponds to the bag opening, and the closed side corresponds to the bag bottom. The unit wall 210 in this embodiment includes six pieces, including two centrally arranged bag bottom unit walls and four side unit walls arranged in pairs on the sides.

[0051] In the pocket-stitching machine, the folding knife device 300 includes a folding knife 310 and a folding knife drive mechanism 320 that is linked to the folding knife 310. The folding knife 310 is composed of multiple pieces, and the folding knife drive mechanism 320 is configured in a corresponding manner to drive the corresponding folding knife 310 to fold the bag-shaped fabric. In this embodiment, the multiple sets of folding knife drive mechanisms 320 are respectively driven by the corresponding cell walls 210. When the cell walls 210 are adjusted relative to the base plate 100, the corresponding folding knife drive mechanisms 320 are also adjusted synchronously, simplifying the position adjustment process of the folding knife 310 and allowing it to adapt to different bag sizes. For example, the folding knife driving mechanism 320 can adopt a cylinder, and 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. The working direction of the folding knife 310 is also determined based on this. 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 cloth. The folding knife driving mechanism 320 drives the folding knife 310 to switch between the initial position and the working position accordingly.

[0052] In one embodiment, to facilitate the installation and movement of the cell walls 210, the pocket-sticking machine mold pantograph mechanism further includes an adjustment seat 230. Multiple, positionally adjustable adjustment seats 230 are connected to the base plate 100, with each cell wall 210 secured to a corresponding adjustment seat 230. The adjustment seat 230 can be slidably mounted directly to the base plate 100. Alternatively, a guide seat 110 can be secured to the bottom side of the base plate 100, with a track 240 slidably mounted on the guide seat 110. The top of the adjustment seat 230 is secured to the track 240, and the guide seat 110 slidably engages with the guide seat 110 via the track 240. The guide seat 110 supports and guides the adjustment seat 230, while the provision of the track 240 facilitates assembly and disassembly of the adjustment seat 230, providing flexible assembly angles and methods. Of course, the guide seat 110 and the track 240 are relative terms, and vice versa. This naming is merely for ease of reading and does not strictly limit their interchangeability.

[0053] Combine Figures 4 to 7In one embodiment, a die drive mechanism 400 is further configured to be capable of synchronously adjusting each cell wall 210. The die drive mechanism 400 can be manually driven or automatically driven to synchronize each cell wall 210. The die drive mechanism 400 includes a torsion shaft 410, with each cell wall 210 being linked to the torsion shaft via a corresponding adjustment seat 230. The torsion shaft 410 is mounted on the base plate 100 with its axis perpendicular to the base plate 100. The torsion shaft 410 itself can be manually driven and / or equipped with a power source. When manually driven, an operating handle can be connected to the top of the torsion shaft 410 for easy gripping or docking with auxiliary tools. When equipped with a power source, a motor 440 or other method can be used for automatic control.

[0054] For example, a bracket 130 is fixed to the base plate 100. The bottom of the bracket 130 is fixed to the base plate 100 via multiple struts. The top of the torsion shaft 410 is rotatably engaged with the bracket 130, while the bottom of the torsion shaft 410 is rotatably engaged with the base plate 100. The rotating shaft of the motor 440 (which may include a speed reduction mechanism) is arranged horizontally to reduce the height of the device. The motor is then transmitted to the vertical torsion shaft 410 via a universal joint 450. The use of the universal joint 450 for transmission not only simplifies the structure but also can compensate for processing and assembly errors to a certain extent.

[0055] In one embodiment, in order to lock the position after adjusting the unit wall 210, a mutually cooperating angle limiting mechanism 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 also be self-locked to maintain the current position of the torsion shaft 410.

[0056] The torsion shaft 410, through a linkage assembly, can simultaneously drive all controlled cell walls 210, resulting in a simple structure, easy operation, and improved work efficiency. All controlled cell walls 210 have at least two adjustment directions, enabling interlocking movement. Independent movement of one cell wall 210 can be constrained by the other cell walls 210. The torsion shaft 410 rotates about an axis perpendicular to the substrate 100, with the cell walls 210 arranged around the axis and circumferentially surrounding it. During adjustment, all cell walls 210 tend to converge toward the torsion shaft 410 or diverge outward from it.

[0057] In one embodiment, in order to guide the movement of the adjustment seat 230, the base plate 100 is provided with 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 inserted into the corresponding guide hole 120 and is connected to the torsion shaft 410 through the transmission member.

[0058] For example, a first transmission member 232 is directly fixed on the adjustment seat 230, and a second transmission member 241 can be set through the track 240 on the adjustment seat 230. When the transmission member needs to be adjusted, it moves along the corresponding guide hole 120, directly or indirectly driving the adjustment seat 230. According to the adjustment direction of the unit wall 210, multiple guide holes 120 are roughly radiated around the torsion axis 410. As for each transmission member itself, it can be a transmission pin fixed upright on the adjustment seat 230 or the track 240, and the shape is not strictly limited.

[0059] In one embodiment, the linkage assembly 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 base plate 100. A coupling hole 422 is provided in the middle of the synchronization plate 420. The bottom of the torsion shaft 410 is fixedly inserted into the coupling hole 422. The bottom of the torsion shaft 410 can also be further extended downward to pass through the synchronization plate 420, and the protruding part is rotatably mounted to the base plate 100.

[0060] The synchronization plate 420 has two strip-shaped synchronization holes 421 defined therein. Each synchronization hole 421 extends obliquely to the radial direction of the torsion shaft 410. Two linkage plates 430 are provided, positioned on opposite radial sides of the torsion shaft 410. The synchronization plates 420 are stacked on top of the two linkage plates 430. A third transmission member 431 is secured to each linkage plate 430. This third transmission member 431 can be a transmission pin or other method vertically fixed to the linkage plate 430. The third transmission member 431 extends into the corresponding synchronization hole 421.

[0061] The synchronizing plate 420 rotates along with the torsion shaft 410, driving the interlocking plates 430 via the synchronizing hole 421 and the third transmission member 431. To limit the direction of movement of the interlocking plates 430, each interlocking plate 430 is provided with a strip-shaped guide hole 433. A guide member (not shown, such as a guide pin) is fixed to the base plate 100 and extends into the guide hole 433. As can be seen in the figure, all guide holes 433 extend in the same direction, for example, in the front-to-back direction. This allows the two interlocking plates 430 to move synchronously in opposite directions, moving toward or away from the torsion shaft 410.

[0062] In order to drive each adjustment seat 230 , each linkage plate 430 is provided with a plurality of driving holes 432 , and the first transmission member 232 and the second transmission member 241 extend into the corresponding driving holes 432 .

[0063] See also Figures 7 to 10Since the movement directions of each unit wall 210 and the linkage plate 430 may not be consistent during adjustment, in one embodiment, for the unit wall 210 that has the same movement direction as the linkage plate 430, a track 240 is fixed to the adjustment seat 230 fixed thereto, and a second transmission member 241 is fixed to the track 240. The second transmission member 241 is fixed to the driving hole 432, that is, it is fixed and directly follows the linkage plate 430.

[0064] See also Figure 11 , Figure 12 In one embodiment, for a unit wall 210 whose movement direction is inconsistent with that of the linkage plate 430, the drive hole 432 is a strip-shaped hole that is obliquely intersected with the corresponding guide hole 120. The first transmission member 232 is fixed to the adjustment seat 230, and the top portion is movable to extend into the drive hole 432 to release the component force in the unintended direction, ensuring smooth movement of the adjustment seat 230 along the guide hole 120. The transmission members of each of the above embodiments can be respectively provided with bearings, and the corresponding bearings can be used to cooperate with the guide hole 120, the synchronization hole 421, or the drive hole 432 to reduce resistance during movement and reduce component wear.

[0065] In the above embodiments, the cell walls 210 are modularly designed to flexibly adapt to the bag size. In some cases, the shape of a cell wall 210 needs to be adjusted, and the cell wall 210 needs to be replaced. In order to facilitate disassembly and maintenance, the following provides a preferred method.

[0066] See also Figure 8 、 Figure 9 In one embodiment, the adjustment seat 230 and the unit wall 210 are detachably connected by magnetic attraction.

[0067] An engaging member 231 is embedded within or at the bottom of the adjustment base 230, and is magnetically attracted to the cell wall 210 via the engaging member 231. For example, the bottom of the adjustment base 230 is provided with multiple engaging grooves spaced apart, and the engaging members 231 are multiple and fixed in corresponding engaging grooves, making the bottom of the adjustment base 230 relatively flat.

[0068] The cell walls 210 can be directly magnetically attracted to the bottom of the adjustment seat 230. A connecting plate 220 can also be fixed to the top surface of the cell walls 210. The connecting plate 220 is in contact with the bottom of the adjustment seat 230. When disassembly is required, the connecting plate 220 and the adjustment seat 230 can be separated by simply overcoming the magnetic attraction, thereby separating the cell walls 210. A complementary snap-fit ​​structure can also be provided between the adjustment seat 230 and the connecting plate 220 to further prevent misalignment and improve assembly accuracy.

[0069] See also Figures 9 to 12The folding knife device 300 is equipped with multiple sets, each set including a folding knife 310 and a corresponding folding knife driving mechanism 320. Each set corresponds to one of the cell walls 210, so that the folding knife driving mechanism 320 and the corresponding folding knife 310 move together with the corresponding cell wall 210. When in use, the folding knife 310 moves relative to each cell wall 210 to switch between the initial position and the working position.

[0070] The folding knife driving mechanism 320 can adopt a motor or a cylinder. In one embodiment, taking the cylinder as an example, the cylinder body of the cylinder is directly or indirectly fixed to the adjustment seat 230. In this embodiment, the adjustment seat 230 is integrally or separately fixed with a cylinder support 330, the cylinder body of the cylinder is fixedly connected to the cylinder support 330, and the piston rod 321 of the cylinder is connected to the movable support 340. The folding knife 310 is detachably installed on the movable support 340.

[0071] Figure 9 Since the two unit walls 210 are adjusted synchronously, they can share the adjustment base 230, but the corresponding two folding knives 310 move independently. Therefore, two sets of folding knife driving mechanisms 320 are installed on the same cylinder support 330, and each cylinder drives the corresponding folding knife 310 respectively.

[0072] In one embodiment, the folding knife 310 can be disassembled by using a locking cylinder 350 to facilitate quick assembly. For example, the folding knife 310 is connected to the movable support 340 through the knife seat assembly 360, wherein the movable support 340 is fixed with a coupling seat 341, and the locking cylinder 350 is installed on the coupling seat 341. The coupling seat 341 is provided with a coupling port, and at least a part of the knife seat assembly 360 is movably inserted and pulled out of the coupling port and is positioned and quickly disassembled and assembled under the action of the locking cylinder 350.

[0073] In one embodiment, the knife holder assembly 360 specifically includes a locking block 361 inserted into the joint, and an adjustment frame connected to the locking block 361. The folding knife 310 is fixedly mounted on the adjustment frame. The cylinder is located above the base plate 100, and the folding knife 310 is gradually lowered through the movable support 340 and the knife holder assembly 360 to be located below the base plate 100.

[0074] The adjustment frame has a first hole 363, and a partial area of ​​the bottom of the locking block 361 is exposed at the bottom of the joint. This part is provided with a hole corresponding to the position of the first hole 363 or a plurality of positioning holes arranged at intervals, and the adjustment frame is fixed to the bottom of the locking block 361 by a fastener (not shown in the figure), so that the folding knife 310 can be adjusted step by step or continuously along the working direction relative to the movable support 340. When the synchronous adjustment of the folding knife 310 and the unit wall 210 cannot meet the needs, the position of the folding knife 310 can be adjusted separately, thereby further improving the versatility of the mold.

[0075] 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, and a first hole 363 is opened in the first adjustment frame 362. The first adjustment frame 362 has a downwardly extending bending portion, and the bending portion is also provided with a second hole 364 extending in the height direction. The second adjustment frame 365 has a horizontally extending portion for fixing the folding knife 310, and also has an upwardly extending bending portion that is in contact with the portion where the second hole 364 is located. The first adjustment frame 362 and the second adjustment frame 365 are then fixed by fasteners (not shown in the figure), and the relative height of the two can be changed, so that the folding knife 310 as a whole is adjustable in height relative to the base plate 100. Adjacent folding knives 310 can be flush with each other in height (edges are adjacent to each other) or staggered and overlapped with each other (edges can be staggered) through height adjustment according to shape and size requirements.

[0076] Based on the above, an embodiment of the present application further provides a pocket patching machine, which is equipped with the adjustable pocket patching machine mold zoom mechanism of each embodiment above. The structure of other parts of the pocket patching machine can be implemented in combination with existing technologies.

[0077] In the adjustable pocket-sticking machine mold scaling mechanism of the present application, the concave mold can be quickly adjusted to adapt to different bag shapes and sizes, which can reduce the production and debugging work of the fixture and further reduce costs.

[0078] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as no contradiction exists between these combinations of technical features, they should be considered to be within the scope of this specification. When technical features in different embodiments are embodied in the same drawing, it can be deemed that the drawing also discloses examples of combinations of the various embodiments involved.

[0079] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
