[0045] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the specification of this application are for illustrative purposes only and do not represent the only implementation method.

[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0048] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediate medium. Moreover, a first feature being “above”, “above”, or “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level (or in a state of use, or from a certain perspective of the drawing) than the second feature.

[0049] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those 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 related listed items.

[0050] In the prior art, the die of the pocket pasting 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 needs to be replaced, which affects the working efficiency.

[0051] See also Figure 1 In one embodiment of the present application, an adjustable pocket-sticking machine die scaling mechanism is provided, including a base plate 100, which can be used as a mounting platform for other components. The base plate 100 has a relative top side and a bottom side, and the die 200 and the folding knife assembly 300 are located on the bottom side of the base plate.

[0052] Combination Figure 2 , Figure 3In this embodiment, 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. 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 lock the position after the adjustment is completed.

[0053] The die wall is generally U-shaped, with an opening side and a closed side opposite to each other. The opening side corresponds to the bag opening, and the closed side corresponds to the bag bottom. The unit wall 210 in this embodiment includes five units, namely, a central bag bottom unit wall, two bottom corner unit walls adjacent to both sides of the bag bottom unit wall, and two side unit walls on both sides of the opening.

[0054] Combination Figure 4 , Figure 5 In order to implement the driving, the pocket sticking machine die scaling mechanism also includes an adjusting member 221, which is movably mounted on the base plate 100, and the adjusting member 221 is transmission-connected with the corresponding unit wall 210, driving the unit wall 210 to adjust its position relative to the base plate 100.

[0055] Each cell wall 210 can be independently configured with an adjusting member 221, that is, each can be adjusted independently, and can interact with the substrate 100 to maintain the adjusted position. For example, the adjusting member 221 is directly or indirectly threaded with the cell wall 210, and is adjusted and maintained in position by tightening or loosening.

[0056] Each unit wall 210 may also be configured with a first driving mechanism 400 that can be adjusted in conjunction with each other. For example, an elevated bracket 130 is fixed above the substrate 100 , and the first driving mechanism 400 is installed on the substrate 100 and the bracket 130 to adjust the position of the die 200 .

[0057] The first driving mechanism 400 includes a torsion shaft 410, which is mounted on the base plate 100. The torsion shaft 410 is manually driven and / or is equipped with a power source. In the following embodiments, the torsion shaft 410 is manually driven as an example, and may be connected with an operating handle 412 for holding or docking auxiliary tools.

[0058] The pocket sticking machine die scaling mechanism also includes a linkage assembly, which is transmission-connected between the torsion shaft 410 and each unit wall 210. Through the rotation of the torsion shaft 410, each unit wall 210 slides relative to the base plate 100 to change the relative position, that is, to adapt to the new bag shape size.

[0059] In this embodiment, the torsion shaft 410 can be rotated manually by operating the operating handle 412. The shape of the operating handle 412 is convenient for docking with other power-assisting tools, such as the polygonal plate shape shown in the figure, and can also have a bayonet, a coupling pin, etc. for docking with other power-assisting tools.

[0060] The torsion shaft 410 can simultaneously drive all controlled cell walls 210 through the linkage assembly, which has a simple structure, is easy to operate, and can improve work efficiency. All controlled cell walls 210 have different adjustment directions, that is, at least two adjustment directions. In this embodiment, all controlled cell walls 210 have different movement directions during adjustment, and generally have a tendency to converge or diverge outward during adjustment.

[0061] In order to guide the movement of the unit wall 210, each unit wall 210 is fixed to the corresponding sliding seat 220, and a guide seat 110 is fixed to the bottom side of the substrate 100. The sliding seat 220 slidably cooperates with the guide seat 110. For example, a track 222 can be fixed to the top of the sliding seat 220, and the sliding seat 220 slidably cooperates with the guide seat 110 through the track 222.

[0062] See also Figure 4 , Figure 5 In order to implement driving, in one of the embodiments, the substrate 100 is provided with a strip-shaped guide hole 120 for each sliding seat 220, and the sliding seat 220 is connected with an adjusting member 221 inserted into the corresponding guide hole 120. The adjusting member 221 and the sliding seat 220 are fixed to each other, and move along the corresponding guide hole 120 when adjustment is required. The multiple guide holes 120 are roughly radially distributed, and the adjusting member 221 itself can be a transmission pin vertically fixed to the sliding seat 220.

[0063] A bracket 130 is fixed on the base plate 100, the top of the torsion shaft 410 is rotationally matched with the bracket 130, and the bottom of the torsion shaft 410 is rotationally matched with the base plate 100. In order to lock the position after adjustment, in one embodiment, a mutually matching angle limiting mechanism is provided between the torsion shaft 410 and the bracket 130 to maintain the angle of the torsion shaft 410, for example, the angle limiting mechanism includes mutually matching arc holes 413 and fasteners 131.

[0064] The top of the torsion shaft 410 is an operating end 411 extending out of the bracket 130, an operating handle 412 is fixed to the operating end 411 and rotates against the top surface of the bracket 130, and an arc hole 413 is opened in the operating handle 412 and arranged around the torsion shaft 410. The bottom of the fastener 131 is fixed to the bracket 130, and the top passes through the arc hole 413 to maintain the relative position of the operating handle 412 and the bracket 130.

[0065] When the unit walls 210 need to be adjusted, the fasteners 131 are first released to allow the operating handle 412 to rotate relative to the bracket 130 . After the adjustment is completed, the operating handle 412 and the bracket 130 are locked by the fasteners 131 to maintain the position of the unit walls 210 .

[0066] 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 . Two strip-shaped synchronization holes 421 are provided on the synchronization plate 420 . The extension direction of each synchronization hole 421 is oblique to the radial direction of the torsion shaft 410 .

[0067] There are two linkage plates 430, which are arranged on two opposite sides of the torsion shaft 410 in the radial direction, and the synchronization plate 420 is stacked on the two linkage plates 430. A transmission member 431 is fixed on each linkage plate 430, and the transmission member 431 can be a transmission pin fixed vertically on the linkage plate 430. The transmission member 431 extends into the corresponding synchronization hole 421.

[0068] The synchronous plate 420 moves by rotating with the torsion shaft 410, and then drives each linkage plate 430 through the synchronous hole 421 and the transmission member 431. In order to limit the movement direction of the linkage plate 430, each linkage plate 430 is provided with a strip-shaped second guide hole 433, and a guide pin 140 extending into the second guide hole 433 is fixed on the base plate 100. It can be seen in the figure that all the second guide holes 433 have the same extension direction, for example, they all extend in the front-to-back direction (corresponding to Figure 2 In the up and down directions in the figure), that is, the two linkage plates 430 can move synchronously in opposite directions and synchronously approach or move away from the torsion shaft 410.

[0069] Each linkage plate 430 is provided with a plurality of driving holes 432 , and the adjusting members 221 extend into the corresponding driving holes 432 . However, it is not strictly required that all adjusting members 221 adopt this transmission method. It can be understood that at least one adjusting member 221 adopts this transmission method.

[0070] Since the movement directions of the unit walls 210 and the linkage plate 430 may not be consistent during adjustment, in one embodiment, for the unit walls 210 with the same movement direction, for example Figure 6 The bag bottom unit wall and the corresponding adjusting member 221 are fixed to the driving hole 432 , that is, fixed and directly follow the linkage plate 430 .

[0071] In one embodiment, for the unit walls 210 with inconsistent movement directions, for example Figure 7 The bottom corner unit wall in the middle, and its corresponding adjustment member 221 movably extends into the driving hole 432. At this time, the driving hole 432 is a strip hole and is obliquely intersected with the corresponding guide hole 120 to release the component force in an unexpected direction, thereby ensuring that the adjustment member 221 moves smoothly along the guide hole 120.

[0072] In the above embodiments, the cell wall 210 adopts a modular design and can flexibly adapt to the bag size. In some cases, the shape of a cell wall 210 itself 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.

[0073] See also Figure 6 , Figure 7 In one embodiment, the sliding seat 220 and the unit wall 210 are detachably connected by magnetic attraction. A track 222 is provided on the top of the sliding seat 220 to cooperate with the guide seat 110. Of course, the guide seat 110 and the track 222 are relative, and vice versa. Such naming is only for the convenience of reading and does not strictly limit whether the positions of the two are interchangeable.

[0074] The track 222 not only plays a role of sliding fit, but can also be further extended to assist in supporting the folding knife assembly 300. When the folding device is in operation, the unit wall 210 is fixed relative to the base plate 100 (the relative position is pre-adjusted and locked), and the folding knife assembly 300 needs to reciprocate to act on the bag-shaped fabric. Therefore, a sliding fit is also adopted between the folding knife assembly 300 and the track 222 to avoid hindering the movement of the folding knife assembly 300.

[0075] The inside or bottom of the sliding seat 220 is embedded with an attraction piece 223, and is magnetically attracted to the unit wall 210 through the magnetic attraction piece 223. A connecting plate 211 may be fixed to the top surface of the unit wall 210, and is attached to the bottom of the sliding seat 220 through the connecting plate 211. When disassembly is required, the unit wall 210 can be separated by overcoming the magnetic attraction force. A complementary shape snap-fit ​​structure may also be provided between the sliding seat 220 and the connecting plate 211 to further avoid misalignment and improve assembly accuracy.

[0076] The folding knife assembly 300 can be implemented in combination with conventional technology. Of course, an improved method is also provided below. In one embodiment, the folding knife assembly 300 includes a folding knife 310 and a second drive mechanism 320 linked to the folding knife 310. The second drive mechanism 320 can adopt a push-pull cylinder 322 fixed on the base plate 100. The folding knife 310 is linked to the piston rod of the push-pull cylinder 322. The folding knife 310 has an initial position and a working position after movement. 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, so as to squeeze and fold the bag-shaped cloth. The second drive mechanism 320 correspondingly drives the folding knife 310 to switch between the initial position and the working position.

[0077] The folding knife assembly 300 is provided with multiple sets, each set corresponding to one of the cell walls 210. Since the folding knife 310 moves relative to each cell wall 210 during operation, in order to adjust the folding knife 310 while adjusting the cell wall 210, and to allow the cell wall 210 and the folding knife 310 to move relative to each other, the connection method between the two is improved, that is, a resetting movable connection is adopted. Specifically, a knife holder 330 is fixed at the tail of the folding knife 310, a guide rod 224 is fixed on the cell wall 210, the knife holder 330 is provided with a first guide hole 331 for the guide rod 224 to slide through, and one end of the guide rod 224 passing through the knife holder 330 is provided with a limiting head 225, so that the folding knife 310 can slide relative to the cell wall 210. On this basis, a reset member 350 is arranged between the cell wall 210 and the knife holder 330, for example, the reset member 350 is a spiral compression spring sleeved on the guide rod 224.

[0078] When the folding knife 310 is disconnected from the second driving mechanism 320, under the action of the reset member 350, the knife seat 330 is pushed toward and blocked by the limit head 225, and the folding knife 310 can maintain a relative position unchanged with the unit wall 210 and adjust its position synchronously with the unit wall 210, and then resume the connection with the second driving mechanism 320 after the adjustment is completed.

[0079] The folding knife 310 and the second drive mechanism 320 are connected in a position-adjustable transmission connection via a locking mechanism 500. The locking mechanism 500 has a locking state for maintaining the linkage between the second drive mechanism 320 and the folding knife 310, and a released state for releasing the linkage. 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 its relative position with the second drive mechanism 320 in the released state.

[0080] The power of the second driving mechanism 320 can be a motor or a cylinder, and a corresponding transmission mechanism is set. In order to drive the folding knife 310, the second driving mechanism 320 as a whole has a movable output member 321 at the downstream side according to the 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 method can specifically adopt a locking cylinder, a manual latch, meshing, tight fit, magnetic attraction, etc.

[0081] Since the adjustment of the cell wall 210 and the folding knife 310 is not in a step-by-step manner, it may only be fine-tuned, or stepless adjustment is required. In order to realize automatic control, an automatic locking member 520 is preferably provided in the position-adjustable transmission connection, that is, the switching between the locked state and the released state can be realized through automatic control, which is also suitable for stepless adjustment. The automatic locking member 520 can, for example, use a locking cylinder to lock or release the handle 340 and allow the handle 340 to slide and adjust.

[0082] In order to facilitate disassembly and assembly, and to maintain the relative position of the folding knife 310 and the second driving mechanism 320 before and after disassembly and assembly, a manual locking member 530 can also be provided in the locking mechanism 500. When in use, the manual locking member 530 remains linked, and when disassembly is required, the linkage is released to implement separation. The manual locking member 530 preferably adopts a structure that can be quickly positioned and disassembled, such as a positioning pin or a snap-fit ​​method, etc.

[0083] Combination Figure 8 , Fig. 9 In one embodiment, in order to realize the above connection mode and load-related components, the locking mechanism 500 includes a coupling seat 510, an automatic locking member 520 and a manual locking member 530. The second driving mechanism 320 is a push-pull cylinder 322, and the output member 321 is a coupling seat fixed to the cylinder piston rod. The manual locking member 530 acts between the coupling seat and the coupling seat 510. For example, the coupling seat is provided with a bar-shaped hole, and the manual locking member 530 ( Figure 6 It can be seen that the locking bolt is arranged on the coupling seat 510 and passes through the adjustment hole. When disassembling, the coupling 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 by the magnetic attraction between the unit wall 210 and the sliding seat 220.

[0084] In one embodiment, a first limiting hole 512 is provided at the bottom of the coupling seat 510, and the handle 340 is inserted into the first limiting hole 512. The automatic locking member 520 is a locking cylinder installed in the coupling seat 510, and the piston rod of the locking cylinder is provided with a limiting head 513 that interacts with the handle 340. In order to adapt to the adjustment and disassembly of the folding knife 310, the handle 340 is provided with a bar hole 341 with one end open, and the piston cylinder of the locking cylinder passes through the bar hole, and the limiting head 513 is located at the end of the piston cylinder passing through the bar hole 341. When adjustment is required, the locking cylinder is released, and the handle 340 can be moved to any position within the travel range relative to the locking cylinder. After the unit wall 210 and the folding knife 310 are adjusted, the locking cylinder re-locks the handle 340.

[0085] 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 corresponds to it. 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 working. If the first direction is parallel to the second direction (such as Figure 6 In the embodiment of the present invention, for example, the bag bottom unit wall and the two bottom corner unit walls, when adjusting the unit wall, the locking mechanism 500 releases the lock of the handle 340 of the folding knife 310 and can be adjusted accordingly without interference in the movement direction.

[0086] In some cases, for example, in two side 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 move directly because it moves along the second direction relative to the second driving mechanism and there is interference in the movement direction.

[0087] To solve this problem, see Fig.10 , Fig.11 In one embodiment, a sliding joint that cooperates along the third direction is provided between the locking mechanism 500 and the second driving mechanism, or in the locking mechanism 500. The sliding joint in the figure includes a slide seat 323 and a slide rail 324 that cooperate with each other, wherein the slide seat 323 is fixed to the bottom of the output member 321, and the slide rail 324 can be fixed to the combination seat 510 and slide along the third direction, wherein the third direction can be perpendicular to the second direction, and the first direction suitable for the movement of the folding knife 310 can be synthesized by the third direction and the second direction. When the unit wall 210 is adjusted, the slide seat 323 and the slide rail 324 both slide adaptively, and the first direction, the second direction and the third direction mentioned above are all arranged on the parallel surface of the substrate 100.

[0088] Based on the above, an embodiment of the present application further provides a pocket sticking machine with an adjustable pocket sticking machine die zoom mechanism of each embodiment above. The structure of other parts of the pocket sticking machine can be implemented in combination with the existing technology.

[0089] In the adjustable pocket-sticking machine die scaling mechanism of the present application, the die 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.
