[0047] See also Figure 1 to Figure 3 In view of the problem of spacing adjustment efficiency of the pocket folding knife of the pocket patching machine in the prior art, an embodiment of the present application provides an automatic adjustment mechanism of the pocket folding knife of the pocket patching machine, including a support assembly 100, the support assembly 100 includes a base plate 110 and two supports 120 fixed to the base plate 110 and arranged opposite to each other, the base plate 110 has a front side and a rear side relative to each other, and a plurality of mounting holes are also provided on the front side, and folding knives at other parts can be installed as needed. This embodiment mainly improves the adjustment method of the pocket folding knife, and the relevant components are mainly distributed on the rear side of the base plate 110.

[0048] The synchronization mechanism 200 is installed on the support assembly 100. The synchronization mechanism 200 is used to drive the two sets of bag mouth folding knife assemblies 300 to move synchronously in opposite directions to ensure the adjustment accuracy and efficiency. The synchronization mechanism 200 can be selected from the form of a screw rod, a synchronous belt, or a gear rack pair, so that the two sets of bag mouth folding knife assemblies 300 are linked. The following embodiments take the screw rod 210 as an example, but it is not a strict limitation.

[0049] The guide shaft 130 is installed between the two supports 120, taking into account both structural reinforcement and movement guidance of the pocket knife assembly 300. The two ends of the guide shaft 130 can be fixed to the supports 120 on the corresponding sides respectively. The guide shaft 130 not only guides the movement of the two sets of pocket knife assemblies 300, but also cooperates with the synchronization mechanism 200 to ensure movement and adjustment accuracy. There are two moving seats 140, both of which are slidably installed on the guide shaft 130. Each moving seat 140 also cooperates with the synchronization mechanism 200 and moves in the opposite direction synchronously; the pocket knife assembly 300 is composed of two sets, each set is installed to the corresponding moving seat 140, and when the screw rod 210 rotates, the two moving seats 140 can drive the pocket knife assembly 300 to change the spacing.

[0050] In order to achieve automatic adjustment, in one embodiment, the automatic adjustment mechanism also includes a motor 220 and a transmission assembly, wherein the motor 220 is installed on one of the supports 120, and the transmission assembly is linked between the motor 220 and the synchronization mechanism 200. By presetting the operating parameters of the motor 220 (such as the number of rotations, etc.), the spacing between the two sets of bag mouth folding knife assemblies 300 can be changed as expected.

[0051] Specifically, the screw rod 210 is a positive and negative thread screw rod, the guide shaft 130 and the screw rod 210 are parallel to each other, and the two are arranged horizontally at approximately the same height. The screw rod 210 has a positive thread segment and a negative thread segment on both sides, and the two movable seats 140 are correspondingly matched with the positive thread segment and the negative thread segment.

[0052] The guide shaft 130 and the screw rod 210 are both mounted above the base plate 110, reserving necessary space for the installation and movement of other components. In one embodiment, the movable seat 140 is L-shaped as a whole, including a first connecting portion 141 located at the upper part and standing upright, and the first connecting portion 141 is provided with two mounting holes, one of which is provided with an internal threaded sleeve 142 that cooperates with the screw rod 210, and the other mounting hole is provided with a linear bearing 144 that cooperates with the guide shaft 130. The second connecting portion 143 is located below the first connecting portion 141, and the bag mouth folding knife assembly 300 is installed below the second connecting portion 143.

[0053] The first connecting portion 141 is slidably disposed on the guide shaft 130 . This matching mode enables the bag opening folding knife assembly 300 to operate smoothly and with less noise when being adjusted.

[0054] In order to drive the screw rod 210, the transmission assembly connected between the motor 220 and the screw rod 210 adopts a synchronous belt. For example, the main shaft of the motor 220 is fixed with a driving wheel 221, and the end of the screw rod 210 is fixed with a driven wheel 222. The synchronous belt 223 is wound and connected between the driving wheel 221 and the driven wheel 222 to realize transmission. The motor 220 is relatively large in size. In order to reduce the occupied space, the motor 220 is located between the two supports 120 and fixed to one of the supports 120. The main shaft of the motor 220 extends out of the support 120 on the corresponding side, and the driving wheel 221 is installed on the extended part. Similarly, the end of the screw rod 210 also extends out of the support 120 on the corresponding side, and the driven wheel 222 is installed on the extended part and wound with a synchronous belt 223. The synchronous belt 223 is obliquely extended between the driving wheel 221 and the driven wheel 222 as a whole.

[0055] As for the pocket folding knife assembly 300 itself, it can be combined with the existing technology. One embodiment of the present application is driven by rotation. For example, the pocket folding knife assembly 300 includes a folding knife cylinder 310 and a folding knife 320. The folding knife cylinder 310 is installed on the second connecting portion 143 in the corresponding movable seat 140. The folding knife cylinder 310 adopts a rotating cylinder. The folding knife 320 is directly or indirectly installed on the rotating shaft of the folding knife cylinder 310. Since the folding knife 320 is located below the bottom plate 110 and the movable seat 140 is located above the bottom plate 110, in order to avoid spatial interference, in one embodiment, the bottom plate 110 is provided with an avoidance opening 111, and a connecting seat 311 is fixed on the rotating shaft of the folding knife cylinder 310. The connecting seat 311 extends to the bottom of the bottom plate 110 through the avoidance opening 111, and the folding knife 320 is fixed to the corresponding connecting seat 311. As required, an escape opening may be provided on the support 120 and connected to the escape opening 111 of the bottom plate 110 to prevent the folding knife cylinder 310 from being blocked by the support 120 on the corresponding side when moving horizontally.

[0056] In order to facilitate signal detection and automatic control, in one embodiment, a sensor 400 for detecting the position of the moving seat 140 is installed on the support 120. The sensor 400 can be fixed on the top of the support 120 directly or by means of a mounting seat, and connected to the electronic control system of the bag sticking machine through a circuit to implement signal transmission. When detecting the position of the moving seat 140, the sensor 400 can directly sense whether the edge of a certain side of the moving seat 140 enters or leaves its detection range, or it can sense the position of the folding knife cylinder 310 or other fixed parts relative to the moving seat 140, and the principle is the same. As for the sensor 400 itself, common types of existing technologies can be used, such as travel switches, photoelectric sensors, Hall sensors, etc. The sensor 400 can sense the position of the moving seat 140, that is, the position of the corresponding folding knife 320, and the generated signal can be used for zero point calibration of the motor 220, or logical linkage with other electronic control devices, etc.

[0057] An embodiment of the present application further provides a pocket sticking machine with the automatic adjustment mechanism of the above embodiments. The structure and working method of other parts of the pocket sticking machine can be implemented in combination with the existing technology.

[0058] When the pocket sticking machine of the present application is working, if the pattern, that is, the pocket size, changes, the electronic control system receives the new pattern, measures the size of both sides of the pocket, and sends a control signal to the motor. Of course, as far as the electronic control method itself is concerned, conventional technology can be used, such as calculating the number of motor rotations or angles according to the change in spacing, the motor runs and drives the lead screw through the transmission assembly, and then the two folding knives realize synchronous reverse movement until the expected spacing is reached to adapt to the new pattern.

[0059] The automatic adjustment mechanism of the pocket folding knife of the pocket pasting machine of the present application can accurately and efficiently adjust the spacing between the two sets of pocket folding knife components through a synchronization mechanism, avoiding the tediousness of manual adjustment one by one. When the pocket size changes, the linked position adjustment can be implemented, which is associated with the sewing pattern and automatically adjusted to the desired position, thereby improving work efficiency.

[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0061] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
