[0048] Regarding the problem of low adjustment, disassembly, and assembly efficiency of folding knives in the prior art, refer toFigure 1 , Figure 2 , the present application provides a folding knife separation and installation mechanism for a patch pocket machine, including:

[0049] A bottom plate 100 for carrying the corresponding movement of all folding knives 200;

[0050] A movable seat 300 slidably arranged relative to the bottom plate 100;

[0051] A driving mechanism 400 installed on the bottom plate 100 and drivingly connected to the movable seat 300;

[0052] A locking mechanism 500 installed on the movable seat 300, having opposite locking states and release states;

[0053] A folding knife 200 with a handle 201, and the handle 201 is inserted and fixed to the locking mechanism 500 in an adjustable manner.

[0054] The bottom plate 100 provides a foundation, the driving mechanism 400 and the movable seat 300 provide a working stroke for the folding knife 200, and the locking mechanism 500 can quickly switch the coupling relationship between the folding knife 200 and the driving mechanism 400, so as to realize the quick disassembly and assembly of the folding knife 200; the folding knife 200 is adapted to the locking mechanism 500 in an adjustable manner, which can realize the quick adjustment of the folding knife 200, thereby effectively improving the adaptability and further improving the production efficiency.

[0055] In the specific implementation form of the locking mechanism 500, referring to one embodiment, the locking mechanism 500 includes:

[0056] A combined seat 502, provided with a jack for the handle 201 to be inserted and a side hole communicating with the jack;

[0057] A locking pin 503 slidably arranged in the side hole. Since the jack communicates with the side hole, the locking pin 503 can act on the handle 201.

[0058] In the figure, the extending directions of the jack and the side hole are perpendicular to each other. During the switching process between the locking state and the release state, the locking pin 503 moves relative to the side hole. Further, the locking pin 503 abuts and limits the handle 201 along the movement direction perpendicular to the handle 201.

[0059] In the locking state, the locking pin 503 occupies at least a part of the space of the jack to limit the movement of the handle 201 relative to the jack, so as to realize the locking of the handle 201.

[0060] Correspondingly, the structure of the folding knife 200 is adapted to the locking mechanism 500. See Figure 2, in one embodiment, the folding knife 200 further includes a blade portion 203 opposite to the handle portion 201, and a strip-shaped hole 202 is provided in the handle portion 201. The length of the strip-shaped hole 202 corresponds to the adjustable length of the folding knife 200 relative to the movable seat 300. In the figure, the length of the strip-shaped hole 202 is close to the movement stroke of the piston rod of the first cylinder 402, that is, the difference range of the lengths does not exceed 30%. Axially of the handle portion 201, the strip-shaped hole 202 occupies at least 1 / 2 of the handle portion 201. The strip-shaped hole 202 is provided in the middle of the handle portion 201. The strip-shaped hole 202 is an open structure on the side away from the blade portion 203. The locking pin 503 passes through the strip-shaped hole 202, and a clamping head 504 for pressing against the handle portion 201 is provided at the end of passing through.

[0061] Since one side of the strip-shaped hole 202 is an open structure, when it needs to be disassembled, after loosening the locking pin 503, the handle portion 201 can be directly pulled out of the jack without being interfered and blocked by the locking pin 503, and the operation is more convenient, improving the efficiency.

[0062] Further, in one embodiment, the folding knife 200 includes:

[0063] A blade portion 203, which is a plate-like structure for folding cloth;

[0064] A connecting seat 204, which is fixed to one side edge of the blade portion 203;

[0065] A handle portion 201, which is rod-shaped and fixed to the connecting seat 204.

[0066] In Figure 2 , the blade portion 203, the connecting seat 204 and the handle portion 201 are arranged in sequence in the left-right direction in the figure, and are stacked in sequence in the up-down direction in the figure. That is, the blade portion 203 is located below the connecting seat 204, and a part of the connecting seat 204 is located below the handle portion 201. The folding knife 200 as a whole is located below the driving mechanism 400.

[0067] The locking mechanism 500 can be implemented manually or through a control component. For example, in one embodiment, the locking pin 503 is provided by a second cylinder 501 or an electric push rod. See Figure 4, a second cylinder 501 is fixed to the bottom of the movable seat 300. The piston rod of the second cylinder 501 serves as a locking pin 503, and the coupling seat 502 is fixed below the second cylinder 501. The locking and releasing states of the locking mechanism 500 can be achieved by the locking pin 503 itself or by the locking pin 503 driving an elastic member. For example, in the figure, when the second cylinder 501 is disconnected from the air source, the piston rod of the second cylinder 501 moves upward under the action of the elastic member, and at the same time, the elastic member presses against the handle portion 201, causing the locking mechanism 500 to enter the locked state; when the second cylinder 501 is connected to the air source, the piston rod of the second cylinder 501 moves downward under the action of the compressed gas, driving the elastic member away from the handle portion 201, and the locking mechanism enters the released state.

[0068] To drive the folding knife 200 to move relative to the coupling seat 502 more smoothly, guide pulleys 505 that cooperate with the side edge of the handle portion 201 are provided near the insertion hole of the coupling seat 502. The guide pulleys 505 are arranged in groups, and each group of guide pulleys 505 includes at least two and are respectively located on both sides of the insertion hole. There are two groups of guide pulleys 505 and they are respectively located on the inlet side and the outlet side of the insertion hole. Correspondingly, the edge of the handle portion 201 of the folding knife 200 can also be chamfered to improve the smoothness during the adaptation process between the two, and the same applies to the side edge inside the strip-shaped hole 202. The second cylinder 501 is assembled to the movable seat 300 through a number of fasteners, and the guide pulleys 505 can share the fasteners with the second cylinder 501 to improve the assembly convenience.

[0069] Whether manually implemented or implemented by a control component, the locking mechanism 500 in the present application can enter the locked state or the released state at any position relative to the folding knife 200, thereby realizing stepless adjustment of the folding knife 200 relative to the movable seat 300 and improving the adaptability of the folding knife to pockets of different sizes.

[0070] Similarly to the implementation of the locking mechanism 500, the driving mechanism 400 can also have various forms. In the figure, the driving mechanism 400 is a first cylinder 402, and the movable seat 300 is connected to the piston rod of the first cylinder 402. The first cylinder 402 is installed on the bottom plate 100 through a cylinder seat 401. At the same time, the movable seat 300, the locking mechanism 500, and the folding knife 200 are assembled to the bottom plate 100 through the first cylinder.

[0071] See Figure 3 , Figure 4 , the movable seat 300 is generally L-shaped and includes:

[0072] A vertical portion 301, which is fixed to the piston rod of the first cylinder 402;

[0073] A horizontal folding portion 302, which extends in a direction away from the first cylinder 402, and the locking mechanism 500 is fixed to the bottom surface of the horizontal folding portion 302. In the figure, the locking mechanism 500 is a second cylinder 501.

[0074] See Figure 1 、 Figure 5 The folding knives 200 are provided in multiple sets and are arranged around the edge of the bottom plate 100. The bottom plate 100 has opposite upper and lower sides. The driving mechanism 400 is fixed above the bottom plate 100, and the blade part 203 extends below the bottom plate 100 via the movable seat 300 and the locking mechanism 500. Each folding knife 200 corresponds to an independent driving mechanism 400, movable seat 300, and locking mechanism 500 respectively. Each driving mechanism 400 is arranged radially with respect to the center of the bag-shaped fabric. The blade parts 203 of each folding knife 200 are set differently for different areas of the bag-shaped fabric. In the figure, there are five sets of folding knives 200, which act on different sides of the pocket fabric respectively, or the acting parts between different folding knives 200 overlap each other.

[0075] Based on the above, in one embodiment of the present application, a pocket-attaching machine is further provided, which has the folding knife separation and installation mechanism of the pocket-attaching machine in the present application. Other parts of the pocket-attaching machine can be implemented in combination with the prior art.

[0076] The working process of the pocket-attaching machine in the present application is implemented as described in the following process:

[0077] When it is necessary to change the style of the processed bag type: The second air cylinder 501 is connected to the air source, and the locking mechanism 500 enters the release state. The handle part 201 of the folding knife 200 can be withdrawn from the joint seat 502 to realize the separation and replacement of the folding knife 200. When the corresponding folding knife 200 is installed at the preset position, the second air cylinder 501 disconnects the air source, and the locking mechanism 500 enters the locking state. The relative position between the handle part 201 of the folding knife 200 and the joint seat 502 is locked, and the first air cylinder 402 can drive the folding knife 200 to move relative to the base through the movable seat 300 to complete the folding operation. The above process can realize the rapid replacement of the folding knife 200.

[0078] When the style of the processed bag type remains unchanged but only the size changes: The second air cylinder 501 is connected to the air source, and the locking mechanism 500 enters the release state. The handle part 201 of the folding knife 200 can move relative to the joint seat 502; after moving the folding knife 200 to the required position, the second air cylinder 501 disconnects the air source, and the locking mechanism 500 enters the locking state. The relative position between the handle part 201 of the folding knife 200 and the joint seat 502 is locked. The above process can realize the rapid adjustment of the folding knife 200.

[0079] 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 falling within the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, the drawing can be regarded as also disclosing the combination examples of the various embodiments involved.

[0080] 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 patent 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 belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
