[0051] To make the above objects, features, and advantages of the present application more apparent and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0052] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it can be directly on the other component or there may also be an intermediate component. 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 at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the specification of the present application are only for the purpose of illustration and do not represent the only implementation manner.

[0053] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0054] In the present application, unless otherwise clearly specified and limited, the first feature may be in direct contact with the second feature or indirectly in contact with the second feature through an intermediate medium when the first feature is "above" or "below" the second feature. Moreover, the first feature may be directly above or obliquely above the second feature when the first feature is "above", "over" and "on top of" the second feature, or it only means that the first feature is higher than the second feature in terms of the horizontal height (or in a use state, or from a certain perspective of the drawing). The first feature may be directly below or obliquely below the second feature when the first feature is "below", "beneath" and "underneath" the second feature, or it only means that the first feature is lower than the second feature in terms of the horizontal height (or in a use state, or from a certain perspective of the drawing).

[0055] 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.

[0056] 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.

[0057] See also Figure 1 , Figure 2 In one embodiment of the present application, a folding knife automatic adjustment mechanism for 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 die 200 and the 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. The first driving mechanism 400 is mounted on the base plate 100 and the bracket 130, and is used to adjust each set of folding knife assemblies 300.

[0058] Each folding knife assembly 300 includes:

[0059] The folding knife 310 has an initial position and a working position after movement;

[0060] The second driving mechanism 320 is installed on the base plate 100 and is used to drive the folding knife 310 to switch between the initial position and the working position;

[0061] The locking mechanism 500 is 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 automatic adjustment mechanism also includes a first drive mechanism 400, which is connected to each set of folding knife assemblies 300. When the bag size changes, the folding knife 310 needs to be adjusted. At this time, the locking mechanism 500 is switched to the released state, and the folding knife 310 is driven and adjusted by the first drive mechanism 400. After the adjustment is completed, 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] During adjustment, since the travel distance between the initial position and the working position of the folding knife 310 is not changed, it can be understood that the initial position of the folding knife 310 is changed relative to the substrate 100. Similarly, the working position is also adjusted to adapt to the change in the pocket size.

[0064] Combined with Figures 3 to 5 , a plurality of linkage seats 220 are installed on the bottom side of the substrate 100. For example, a sliding installation method can be adopted. Each folding knife 310 is respectively movably installed on the corresponding linkage seat 220 to adapt to the switching between the initial position and the working position. The folding knife 310 follows the linkage seat 220 during adjustment.

[0065] An intermediate member 210 is provided at the bottom of the linkage seat 220 by a fixed connection or a detachable connection method. The detachable connection method is selected from at least one of a magnetic attraction fit, a sliding positioning fit, and a fastener fit.

[0066] The first driving mechanism 400 uses the same power device (such as the motor 440 below) in cooperation with an improved transmission mechanism to simultaneously drive all the controlled linkage seats 220 and then drive the folding knife 310 to adjust the initial position and the working position via the intermediate member 210.

[0067] All the folding knives 310 controlled by the first driving mechanism 400 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 from each other.

[0068] For the adjustment of each folding knife 310, a conventional power mechanism and a position locking mechanism can be respectively configured. In this embodiment, in order to further improve the efficiency, a plurality of folding knives 310 are adjusted synchronously, which simplifies the equipment structure and reduces the cost.

[0069] A guide seat 110 is fixed to the bottom side of the substrate 100. A track 222 can be fixed to the top of the linkage seat 220 and is slidably matched with the guide seat 110 through the track 222. Of course, the guide seat 110 and the track 222 are relative. Vice versa, such naming is only for easy reading and does not strictly limit whether the positions of the two are interchanged.

[0070] In the released state of the locking mechanism 500, the relative position relationship between the linkage seat 220 and the folding knife 310 can be maintained through the reset member 350 to achieve synchronous adjustment. During normal operation, when the folding knife 310 moves from the initial position to the working position, the reset member 350 deforms or moves adaptively, and the positions of the linkage seat 220 and the intermediate member 210 relative to the substrate 100 remain unchanged.

[0071] In order to implement the drive, in one of the embodiments, the substrate 100 is provided with a strip-shaped guide hole 120 for each linkage seat 220, and the linkage seat 220 is connected with a first transmission member 221 inserted into the corresponding guide hole 120. The first transmission member 221 and the linkage 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 linkage seat 220.

[0072] In one embodiment, the first driving mechanism 400 includes a motor 440 as a power device. The motor 440 has the advantages of being easy to control and having high adjustment accuracy. It can also cooperate with a sensor to detect the position signal of the moving part, provide information feedback and control accordingly. After the adjustment is completed, the motor 440 is self-locked to maintain the relative position of each intermediate member 210 and the base plate 100, that is, to maintain the initial position of the folding knife 310. The transmission cooperation between the motor 440 and the first transmission member 221 can adopt different forms such as cams, connecting rods, gears, etc., and the following also provides a preferred method.

[0073] In one embodiment, the motor 440 is mounted on the bracket 130, and the motor shaft of the motor 440 is connected to the torsion shaft 410 through the universal joint 450. The torsion shaft 410 is vertically arranged, that is, perpendicular to the base plate 100, while the motor 440 is horizontally arranged to reduce space occupation, and the universal joint 450 can effectively transmit and load a large torque. The top of the torsion shaft 410 is rotatably matched with the bracket 130, and the bottom of the torsion shaft 410 is rotatably matched with the base plate 100. A synchronization plate 420 located above the base plate 100 is also fixed to the bottom of the torsion shaft 410. Two strip-shaped synchronization holes 421 are provided 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.

[0074] In one embodiment, in order to link multiple folding knives 310, a linkage plate 430 is further provided, and there are two linkage plates 430, which are respectively 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 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.

[0075] 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 2In the up-and-down direction), the two linkage plates 430 can approach or move away from the torsion shaft 410 synchronously and in opposite directions.

[0076] Each linkage plate 430 is provided with a plurality of driving holes 432, and different first transmission members 221 extend into the corresponding driving holes 432. It is not strictly required that all the first transmission members 221 adopt this transmission method, and it is understood that at least one first transmission member 221 adopts this transmission method.

[0077] Since the movement directions of the folding knives 310 and the linkage plates 430 may not be the same during adjustment, in one embodiment, for the folding knives 310 whose movement directions are the same as those of the linkage plates 430, the corresponding first transmission members 221 can be fixed in the corresponding driving holes 432, that is, directly follow the linkage plates 430.

[0078] In one embodiment, for the folding knives 310 whose movement directions are not the same as those of the linkage plates 430, the corresponding first transmission members 221 extend into the driving holes 432 movably. At this time, the driving holes 432 are strip-shaped holes and are obliquely intersecting with the corresponding guiding holes 120, that is, their projections along the vertical direction have an overlapping area, so as to release the component forces in unexpected directions and ensure the smooth movement of the first transmission members 221 along the guiding holes 120.

[0079] In one embodiment, a female mold 200 is further installed on the bottom side of the substrate 100. The female mold 200 itself can be combined with the prior art and has a female mold wall matching the preset bag shape. As one of the improvements of the present application, the female mold wall adopts a split structure, including a plurality of unit walls. In the improved embodiment, the intermediate member 210 is the unit wall, and a plurality of intermediate members 210 together form the female mold 200. When adjusting the folding knives 310, the unit walls can be adjusted synchronously to adapt to different bag sizes.

[0080] As a whole, the female mold wall is generally U-shaped, having an opposite opening side and a closed side. The opening side corresponds to the bag mouth part, and the closed side corresponds to the bag bottom part. In this embodiment, the intermediate member 210, that is, the unit wall, 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 located on both sides of the opening.

[0081] 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. Among them, the bag bottom unit wall directly follows the linkage plate 430, and the adjustment directions of the remaining four unit walls are not the same as the movement direction of the linkage plate 430. In the above embodiment, the unit walls adopt a modular design and can flexibly adapt to the bag size.

[0082] In some cases, when the shape of a certain unit wall or folding knife itself needs to be adjusted, in order to facilitate disassembly and replacement, a preferred method is provided below.

[0083] See Figure 6 and Figure 7 In one embodiment, the linkage seat 220 and the middleware 210 are detachably connected in a magnetic attraction manner. The track 222 on the top of the linkage seat 220 not only plays a role in sliding fit, but can also be further extended to assist in supporting the folding knife assembly 300. In different embodiments, the track 222 can be fixedly or slidably fitted to the top of the linkage seat 220. Since the middleware 210 is fixed relative to the substrate 100 (the relative position is pre-adjusted in place and locked) when the folding device is working, and the folding knife assembly 300 needs to reciprocate to act on the bag-shaped fabric, 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.

[0084] A magnetic attracting member 223 is embedded inside or at the bottom of the linkage seat 220, and the middleware 210 is magnetically attracted through the attracting member 223. A connecting plate 211 can be fixed on the top surface of the middleware 210 and is attached to the bottom of the linkage seat 220. When disassembly is required, only the magnetic attraction needs to be overcome to separate the middleware 210 and the folding knife 310 from the linkage seat 220. A clamping structure with complementary shapes can also be provided between the linkage seat 220 and the connecting plate 211 to further avoid misalignment with each other and improve the assembly accuracy.

[0085] In one embodiment, the second driving mechanism 320 in the folding knife assembly 300 can adopt a push-pull cylinder 322 fixed on the substrate 100. The folding knife 310 is linked with the piston rod of the push-pull cylinder 322. When used in cooperation 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 to squeeze and fold the bag-shaped fabric.

[0086] Multiple sets of folding knife assemblies 300 are configured. As for the whole patch pocket machine, the folding knife assemblies 300 shown in the figure and the embodiments do not strictly require all the folding knife assemblies 300. In this embodiment, each set of folding knife assemblies 300 corresponds to one middleware 210. Since the folding knife 310 moves relative to each middleware 210 during operation, in order to adjust the folding knife 310 while adjusting the middleware 210 and allowing relative movement between the middleware 210 and the folding knife 310 during operation, in one embodiment, the connection method between the two is improved, that is, a resetable movable connection is adopted.

[0087] Specifically, a knife holder 330 is fixed to the tail of the folding knife 310, a guide rod 224 is fixed to the linkage seat 220 or the intermediate member 210, the knife holder 330 is provided with a first guide hole 331 for the guide rod 224 to slide through, and the end of the guide rod 224 passing through the knife holder 330 is provided with a limit head 225. In this way, it is equivalent to that the folding knife 310 can slide relative to the intermediate member 210. On this basis, a reset member 350 is arranged between the intermediate member 210 and the knife holder 330. For example, the reset member 350 is a spiral compression spring sleeved on the guide rod 224. After the folding knife 310 moves, under the action of the reset member 350, the relative position with the intermediate member 210 can be maintained. For example, the reset member 350 pushes the knife holder 330 until it is blocked by the limit head 225. When the folding knife 310 is disengaged from the second driving mechanism 320, the folding knife 310 can synchronously adjust the initial position following the intermediate member 210, and then resume the linkage with the second driving mechanism 320 after the adjustment is completed.

[0088] A position-adjustable transmission connection is realized between the folding knife 310 and the second driving mechanism 320 through a locking mechanism 500. The position-adjustable transmission connection method can specifically adopt a locking cylinder, a manual bolt, meshing, a tight fit, magnetic attraction, etc. When the locking mechanism 500 is in the released state, the folding knife 310 is allowed to change its relative position with the second driving mechanism 320.

[0089] The locking mechanism 500 can include a combination seat 510 and a locking member. The combination seat 510 is mainly used for the transitional connection between the folding knife 310 and the second driving mechanism 320, provides a structural basis for cooperation with other components, and necessary support. The locking member itself can change the locked or unlocked state, so that the locking mechanism 500 switches between the locked state and the released state. According to different driving types, the locking member can be an automatic locking member 520 or a manual locking member 530. The driving method of the automatic locking member 520 is to automatically switch the state of the locking mechanism 500 according to a control signal through a linked power source (such as a motor, a cylinder, etc.); while the driving method of the manual locking member 530 is manual operation to switch the state of the locking mechanism 500.

[0090] In the locking mechanism 500, multiple locking members of the same type or multiple locking members of different types can be configured. Between the second driving mechanism 320 and the combination seat 510, and between the combination seat 510 and the folding knife 310, at least one locking member capable of switching the state of the locking mechanism is configured. When locking members are configured, the types of the locking members can be the same or different.

[0091] Specifically, the transmission method between the second driving mechanism 320 and the folding knife 310 can be:

[0092] In method a), the second driving mechanism 320 is directly driven by the coupling seat 510, and the coupling seat 510 and the folding knife 310 are driven by an automatic locking member 520 or a manual locking member 530.

[0093] The direct drive does not strictly limit the number of components participating in the drive. It is only relative to the automatic locking member 520 and the manual locking member 530, that is, the direct drive always maintains a drive connection during normal use and cannot switch the state of the locking mechanism 500.

[0094] In method b), the second driving mechanism 320 and the coupling seat 510 are driven by a first automatic locking member, and the coupling seat 510 and the folding knife 310 are driven by direct drive, a second automatic locking member, or a manual locking member.

[0095] As a further illustration, automatic locking members can be used simultaneously between the second driving mechanism 320 and the coupling seat 510, and between the coupling seat 510 and the folding knife 310. Of course, the automatic locking members at the two places are configured separately.

[0096] In method c), the second driving mechanism 320 and the coupling seat 510 are driven by a first manual locking member, and the coupling seat 510 and the folding knife 310 are driven by direct drive, an automatic locking member, or a second manual locking member.

[0097] As a further illustration, manual locking members can be used simultaneously between the second driving mechanism 320 and the coupling seat 510, and between the coupling seat 510 and the folding knife 310. Of course, the manual locking members at the two places are configured separately.

[0098] In one embodiment, the power of the second driving mechanism 320 can be in the form of a motor or a cylinder, etc., 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 that is located on the downstream side and is movable in 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.

[0099] Since the adjustment of the initial position of the folding knife 310 is not in a step-by-step manner, it may only be fine-tuning or requires stepless adjustment. To achieve automatic control, an automatic locking member 520 is preferably provided in the position-adjustable drive connection, and the switching between the locked state and the released state can be achieved 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.

[0100] For the convenience of disassembly and assembly and to maintain the relative position between the folding knife 310 and the second driving mechanism 320 before and after disassembly and assembly, a manual locking member 530 may be provided in the locking mechanism 500. During use, the manual locking member 530 remains in linkage. When disassembly is required, the linkage is released for separation. The manual locking member 530 preferably adopts a structure that can be quickly positioned for disassembly and assembly, such as a positioning pin or a clamping method, etc.

[0101] Combined with Figure 8 、 Figure 9 , in one embodiment, in order to implement the above connection method and carry 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.

[0102] In one embodiment, the second driving mechanism 320 is a push-pull cylinder 322, and the output member 321 is a connection seat fixed to the cylinder piston rod. The manual locking member 530 acts between the connection seat and the combination seat 510. For example, the connection seat is provided with a strip hole, and the manual locking member 530 is a locking bolt provided on the combination seat 510 and passing through the adjustment hole. Another example is that there are mating pin holes between the connection seat and the combination seat 510, and the manual locking member 530 is a positioning pin inserted into the corresponding pin hole. During disassembly, the combination seat 510 and the second driving mechanism 320 can be quickly separated through the manual locking member 530. In cooperation with the magnetic attraction between the intermediate member 210 and the linkage seat 220, the intermediate member 210 and the corresponding folding knife assembly 300 can be quickly removed.

[0103] In one embodiment, the bottom of the combination seat 510 is provided with a first limit hole 512, and the handle portion 340 is inserted into the first limit hole 512. The automatic locking member 520 is a locking cylinder installed in the combination seat 510. A limit head 513 acting on the handle portion 340 is provided on the piston rod of the locking cylinder. In order to adapt to the adjustment, disassembly and assembly of the folding knife 310, the handle portion 340 is provided with a strip hole 341 with one end open. The piston cylinder of the locking cylinder passes through the strip hole 341, and the limit head 513 is located at one end where the piston cylinder passes out of the strip hole 341. When adjustment is required, the locking cylinder is released, and the handle portion 340 can move relative to the locking cylinder to any position within the stroke range. After the intermediate member 210 and the folding knife 310 are adjusted by using the first driving mechanism 400, the locking cylinder locks the handle portion 340 again.

[0104] The adjustment direction of the folding knife 310 is restricted by the guiding hole 120, and the arrangement directions of the guiding seat 110 and the track 222 are corresponding to it. For example, the extending direction of the guiding hole 120 is the first direction, and the folding knife 310 moves along the second direction during operation. If the first direction is parallel to the second direction, when adjusting, after the locking mechanism 500 releases the locking of the handle 340 of the folding knife 310, it can be adjusted following the movement, and there is no interference in the movement direction.

[0105] 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 an interference in the movement direction with the first direction.

[0106] To solve this problem, refer to Figure 10 、 Figure 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 within the locking mechanism 500. The setting manner of the sliding joint can be that the combination seat 510 itself is a split structure with sliding fit. One part of the split structure is connected to the second driving mechanism 320, and the other part is connected to the folding knife 310.

[0107] The sliding joint in the figure includes a sliding seat 323 and a sliding rail 324 that cooperate with each other. Among them, the sliding seat 323 is fixed to the bottom of the connecting seat serving as the output member 321, and the sliding rail 324 can be fixed to the combination seat 510 and slide along the third direction. The third direction can be perpendicular to the second direction. Through the third direction and the second direction, a first direction suitable for the movement of the folding knife 310 can be synthesized. When adjusting the folding knife 310, both the sliding seat 323 and the sliding rail 324 slide adaptively. The above-mentioned first direction, second direction, and third direction are all arranged in a plane parallel to the substrate 100.

[0108] Based on the above, an embodiment of the present application further provides a pocket-attaching machine with the folding knife automatic adjustment mechanism for the pocket-attaching machine in the above embodiments. The structures of other parts of the pocket-attaching machine can be implemented in combination with the prior art.

[0109] In the folding knife automatic adjustment mechanism for the pocket-attaching machine of the present application, multiple folding knives can be synchronously and quickly adjusted to adapt to different pocket sizes. By combining with automatic control for scaling, the production and debugging of jigs can be reduced, and the cost can be further reduced.

[0110] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combination examples of the respective embodiments involved.

[0111] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the appended claims.
