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.

[0055] In the prior art, the folding knife, the die and the bag-shaped plate of the pocket pasting machine cooperate with each other to act on the bag-shaped cloth, wherein the folding knife can fold the edge of the bag-shaped cloth. When the bag size changes, the folding knife needs to be replaced or adjusted, which affects the working efficiency.

[0056] See also Figure 1 to Figure 3 In one embodiment of the present application, a folding knife synchronous adjustment mechanism of a pocket sticking machine is provided, comprising a base plate 100 and a plurality of folding knife assemblies 300 mounted on the base plate 100. As far as the pocket sticking machine is concerned, the plurality of folding knife assemblies 300 are not strictly limited to all folding knife assemblies 300 in the pocket sticking machine, but at least two or more sets are included. The base plate 100 can be used as a mounting platform for other components. The base plate 100 has a top side and a bottom side opposite to each other. The concave mold 200 and the folding knife assembly 300 are located on the bottom side of the base plate. Each set of folding knife assembly 300 includes:

[0057] A folding knife 310 having a working position for interacting with the bag-shaped cloth;

[0058] A second driving mechanism 320 is mounted on the base plate 100 and is used to drive the folding knife 310;

[0059] The linkage assembly is transmission-connected to the folding knives 310 in at least two sets of folding knife assemblies, and is used for linkage-adjusting the working positions of the corresponding folding knives 310, that is, adapting to the new bag shape size.

[0060] The folding knife synchronous adjustment mechanism of this embodiment can use the linkage assembly to synchronously adjust multiple folding knives 310, greatly improving work efficiency. After the folding knife 310 changes its working position, it can adapt to changes in the bag size. Since the folding knife 310 is a moving part, it has a relative initial position and working position before and after adjustment. When in use, the folding knife 310 reciprocates between the initial position and the working position. If the travel distance between the initial position and the working position is kept unchanged during adjustment, it can also be understood that the initial position is adjusted.

[0061] Each folding knife assembly also includes a locking mechanism 500 connected between the second driving mechanism 320 and the folding knife 310. The locking mechanism 500 has a locking state for maintaining the linkage between the second driving mechanism 320 and the folding knife 310, and a releasing state for releasing the linkage.

[0062] The folding knife synchronous adjustment mechanism also includes a first drive mechanism 400 and is connected to each set of folding knife assemblies 300. When the bag size changes, the initial position of the folding knife 310 needs to be adjusted. At this time, the locking mechanism 500 is switched to the released state, and the initial position of the folding knife 310 is driven and adjusted by the first drive mechanism 400. After the adjustment is completed, the folding knife 310 is in the new initial position, and the locking mechanism 500 is switched to the locked state, that is, the folding knife 310 is connected to the second drive mechanism 320 again.

[0063] Combination Figure 3 to Figure 5 The first driving mechanism 400 includes a torsion shaft 410, which is movably mounted on the base plate 100. The torsion shaft 410 can be manually driven and / or configured with a power source. When manually driven, the torsion shaft 410 can be connected to an operating handle 412 that is convenient for holding or docking auxiliary tools.

[0064] The shape of the operating handle 412 can be set to facilitate docking with other power-assisting tools, such as the polygonal plate shape in the figure, and can also have a bayonet, a coupling pin, etc. for docking with other power-assisting tools.

[0065] The torsion shaft 410 can simultaneously drive all the controlled folding knives 310 through the linkage assembly, which has a simple structure, is easy to operate, and can improve work efficiency. All the controlled folding knives 310 have different adjustment directions, that is, at least two adjustment directions. In this embodiment, all the controlled folding knives 310 have different movement directions during adjustment, and generally have a tendency to converge or diverge outwards during adjustment.

[0066] In order to guide the movement of the folding knife 310, a sliding seat 220 is installed and positioned on the bottom side of the base plate 100. The bottom of the sliding seat 220 is detachably provided with an intermediate piece 210 by means of magnetic attraction. Each folding knife 310 is movably installed on the intermediate piece 210 through a reset piece 350, which is more convenient for disassembly, assembly and maintenance.

[0067] 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 a first transmission member 221 inserted into the corresponding guide hole 120. The first transmission 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 first transmission member 221 itself can be a transmission pin vertically fixed to the sliding seat 220.

[0068] When the locking mechanism 500 is in the released state, the sliding seat 220 and the folding knife 310 can maintain a relative position relationship through the reset member 350 to achieve synchronous adjustment. During normal operation, the folding knife 310 moves from the initial position to the working position, the reset member 350 adaptively deforms or moves, and the positions of the sliding seat 220 and the intermediate member 210 remain unchanged relative to the base plate 100.

[0069] 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.

[0070] 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 fastener 131 passes through the arc hole 413 to maintain the relative position of the operating handle and the bracket.

[0071] When adjustment is required, the fastener 131 is 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 fastener 131 .

[0072] 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 .

[0073] There are two linkage plates 430, which are arranged at 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 second transmission member 431 is fixed on each linkage plate 430, and the second transmission member 431 can be a transmission pin fixed vertically on the linkage plate 430 and extends into the corresponding synchronization hole 421.

[0074] 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 second 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), that is, the two linkage plates 430 can move synchronously and oppositely toward or away from the torsion shaft 410.

[0075] Each linkage plate 430 is provided with a plurality of driving holes 432 , and different first transmission members 221 extend into corresponding driving holes 432 , but it is not strictly required that all first transmission members 221 adopt this transmission mode, and it can be understood that at least one first transmission member 221 adopts this transmission mode.

[0076] Since the movement directions of each folding knife 310 and the interlocking plate 430 may not be consistent during adjustment, in one embodiment, for the folding knife 310 that has the same movement direction as the interlocking plate 430, its corresponding first transmission member 221 can be fixed in the driving hole 432, that is, it directly follows the interlocking plate 430.

[0077] In one of the embodiments, for the folding knife 310 whose movement direction is inconsistent with the linkage plate 430, its corresponding first transmission member 221 is movably extended into the driving hole 432. At this time, the driving hole 432 is a strip hole and is oblique to the corresponding guide hole 120 to release the component force in an unexpected direction, thereby ensuring that the first transmission member 221 moves smoothly along the guide hole 120.

[0078] In one of the embodiments, a die 200 is further installed on the bottom side of the substrate 100. The die 200 itself can be combined with the existing technology and have 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. In the improved embodiment, the middle piece 210 is the unit wall, and a plurality of middle pieces 210 together constitute the die 200. When adjusting the folding knife 310, the unit walls can be adjusted synchronously to adapt to different bag sizes.

[0079] 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 intermediate piece 210, i.e., the unit wall, in this embodiment includes five pieces, 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.

[0080] The bag bottom unit wall and the two bottom corner unit walls are linked to one of the linkage plates, and the two side unit walls are linked to the other linkage plate. The bag bottom unit wall directly follows the linkage plate 430, and the adjustment direction of the other four unit walls is inconsistent with the movement direction of the linkage plate 430. The unit wall adopts a modular design and can flexibly adapt to the bag shape and size. In some cases, when a unit wall or the shape of the folding knife itself needs to be adjusted, it needs to be disassembled and replaced. In order to facilitate disassembly and maintenance, the following also provides a preferred method.

[0081] See also Figure 6 , Figure 7 In one embodiment, the sliding seat 220 and the middle piece 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 to each other, and vice versa. Such naming is only for the convenience of reading and does not strictly limit whether the positions of the two can be interchanged.

[0082] 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 middle piece 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.

[0083] A magnetic attraction piece 223 is embedded inside or at the bottom of the sliding seat 220, and is magnetically attracted to the middle piece 210 through the attraction piece 223. A connecting plate 211 may be fixed to the top surface of the middle piece 210, and is attached to the bottom of the sliding seat 220 through the connecting plate 211. When disassembly is required, the middle piece 210 and the folding knife 310 can be separated from the sliding seat 220 by overcoming the magnetic attraction force. A complementary-shaped 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.

[0084] In one embodiment, the second driving mechanism 320 in the folding knife assembly 300 can adopt a push-pull cylinder 322 fixed on the base plate 100, and the folding knife 310 is linked with the piston rod of the push-pull cylinder 322. When the die and the bag-shaped plate clamp the bag-shaped cloth, 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 squeeze and fold the bag-shaped cloth.

[0085] The folding knife assembly 300 is configured in multiple sets, each set corresponds to one of the middle pieces 210. As for the pocket sticking machine as a whole, the folding knife assembly 300 shown in this embodiment or the figure is not strictly limited to all the folding knife assemblies 300 in the pocket sticking machine, but includes at least two sets.

[0086] Since the folding knife 310 moves relative to each intermediate member 210 during operation, in order to adjust the folding knife 310 while adjusting the intermediate member 210, and to allow the intermediate member 210 and the folding knife 310 to move relative to each other during operation, in one embodiment, the connection method between the two is improved, that is, a repositionable movable connection is adopted. Specifically, a knife seat 330 is fixed to the tail of the folding knife 310, a guide rod 224 is fixed to the sliding seat 220 or the intermediate member 210, and the knife seat 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 seat 330 is provided with a limiting head 225, such as This is equivalent to the folding knife 310 being able to slide relative to the middle piece 210. On this basis, a reset member 350 is arranged between the middle piece 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 folding knife 310 moves, the relative position with the middle piece 210 can be maintained under the action of the reset member 350. For example, the reset member 350 pushes the knife seat 330 until it is blocked by the limit head 225. When the folding knife 310 is released from the linkage with the second driving mechanism 320, the folding knife 310 can follow the middle piece 210 to adjust the initial position synchronously, and then restore the linkage with the second driving mechanism 320 after the adjustment is completed.

[0087] The folding knife 310 and the second driving mechanism 320 are connected in a position-adjustable transmission connection through the locking mechanism 500, and the position-adjustable transmission connection can be specifically connected by a locking cylinder, a manual latch, meshing, tight fit, magnetic attraction, etc. When the locking mechanism 500 is released, the relative position of the folding knife 310 and the second driving mechanism 320 is allowed to change.

[0088] In one embodiment, the power of the second driving mechanism 320 can be in the form of 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 an output member 321 located on the downstream side and movable according to the transmission order. 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.

[0089] Since the initial position of the folding knife 310 is not adjusted step by step, it may only be fine-tuned or steplessly adjusted. In order to realize automatic control, an automatic locking member 520 is preferably provided in the position-adjustable transmission connection, which can realize the switching between the locked state and the released state through automatic control, and 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.

[0090] 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.

[0091] 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 (see Figure 5) is a locking bolt disposed on the coupling seat 510 and passing 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 intermediate member 210 and the corresponding folding knife assembly 300 can be quickly removed by the magnetic attraction between the intermediate member 210 and the sliding seat 220.

[0092] 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 341, and the limiting head 513 is located at the end where the piston cylinder passes 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 adjustment of the intermediate member 210 and the folding knife 310 is implemented, the locking cylinder re-locks the handle 340.

[0093] The adjustment direction of the folding knife 310 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 a first direction, and the folding knife 310 moves along a 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, when adjusting, 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.

[0094] In some cases, the first direction and the second direction are inclined to each other, and the folding knife 310 cannot be directly adjusted along the first direction because the folding knife 310 can only move along the second direction relative to the second driving mechanism, and there is a movement direction interference with the first direction.

[0095] 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 a first direction suitable for the movement of the folding knife 310 can be synthesized by the third direction and the second direction. When the folding knife 310 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.

[0096] Based on the above, an embodiment of the present application further provides a pocket sticking machine, which has the folding knife synchronous adjustment mechanism of the pocket sticking machine of each embodiment above. The structure of other parts of the pocket sticking machine can be implemented in combination with the existing technology.

[0097] In the folding knife synchronous adjustment mechanism of the bag pasting machine of the present application, multiple folding knives can be adjusted synchronously and quickly to adapt to different bag shapes and sizes, which can reduce the production and debugging of fixtures and further reduce costs.
