Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to an adjustable folding knife mechanism. Background Technology

[0002] In garment manufacturing, pocket opening machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on clothing for users to place small items such as mobile phones, wallets, and keys. The processing of the pocket opening involves cutting, folding, shaping the pocket lip, and sewing. Cutting involves cutting the pocket opening into the predetermined shape; folding involves folding the cut opening inwards to form a folded edge; and shaping the pocket lip involves placing the pocket lip on the folded edge. Therefore, pocket opening machines typically require a folding knife mechanism to fold the cut fabric to form the pocket lip.

[0003] The existing folding knife mechanisms on the market are usually of fixed size and cannot fold bags of different sizes. If the required bag size changes, the entire folding knife mechanism needs to be replaced, so the compatibility is not very good. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, an adjustable folding knife mechanism includes a fixed plate 1, a drive motor 2 mounted on one side of the fixed plate 1, and an L-shaped support 3 movably mounted on the other side of the fixed plate 1. The drive motor 2 passes through the fixed plate 1 and drives the support 3 to move longitudinally. A folding knife mechanism 4 is provided at the lower end of the support 3. The rotation of the shaft of the drive motor 2 drives the support 3 to move up and down, realizing the function of the folding knife mechanism 4 moving up and down. This design can be installed on an automatic pocket opening machine for folding pockets. A cylinder 5 is provided on the support 3 to link the folding knife mechanism 4. The extension and retraction of the cylinder 5 drives the folding knife mechanism 4 to move laterally to fold the cut fabric to form the pocket lip.

[0024] The folding knife mechanism 4 includes a first folding knife assembly 6 and a second folding knife assembly 7. The second folding knife assembly 7 is symmetrical to the first folding knife assembly 6. The first folding knife assembly 6 and the second folding knife assembly 7 move laterally at the same time, and the first folding knife assembly 6 moves in the opposite direction to the second folding knife assembly 7. This design folds the fabric by moving the two folding knife assemblies laterally. Compared with the traditional folding knife which folds the fabric by rotating, the folding knife mechanism 4 of this design has a controllable range of motion and can fold smaller or larger pockets.

[0025] Both the first folding knife assembly 6 and the second folding knife assembly 7 include a downwardly extending connecting plate 8, a folding knife mounting block 9 fixed to the end of the connecting plate 8, several folding knives 10 mounted on the folding knife mounting block 9, and a detachable folding knife limiting block 11 mounted on the folding knife mounting block 9. This design allows for adjusting the number of folding knives 10 to change the size of the folding knives according to the required bag size, enabling the folding of different sized pockets. This achieves a universal compatibility effect; to handle different sized pockets, only the number of folding knives 10 needs to be increased or decreased without replacing the entire folding knife mechanism 4. It is convenient to use and easy to operate.

[0026] The folding knife limiting block 11 is fixed to the folding knife mounting block 9 by screws, pressing down on the folding knife 10 from above to limit its movement. To install or remove the folding knife 10, remove the screws and take out the folding knife limiting block 11. After adjusting the number of folding knives 10, fix the folding knife limiting block 11 back in place using screws.

[0027] The folding knife mounting block 9 has a recessed mounting groove 12, and the folding knife 10 has a mounting block 13 adapted to the contour of the mounting groove 12 below it. The folding knife 10 is assembled by embedding the mounting block 13 into the mounting groove 12.

[0028] An inclined guide portion 14 is provided on one side of the mounting groove 12, and the mounting block 12 also has an inclined surface with a guide portion on one side. When installing the folding knife 10, it can be inserted into the mounting groove 12 along the guide portion 14, which helps to make the assembly of the folding knife 10 easier and also increases the contact surface between the mounting block 13 and the mounting groove 12.

[0029] On the other side of the mounting groove 12, a limiting step 15 is provided. When the mounting block 13 is assembled, it fits into the limiting step 15, further increasing the contact surface between the mounting block 13 and the mounting groove 12, increasing the friction, and increasing the stability of the folding knife 10 after assembly.

[0030] The folding knife 10 includes a horizontal mounting rod 16, a vertical push rod 17, and a bag-folding rod 18 extending outward from the end of the push rod 17. The mounting block 13 is located at the bottom of the mounting rod 16 and is assembled onto the folding knife mounting block 9 via the mounting rod 16. The mounting block 13 is embedded in the mounting groove 12.

[0031] The mounting rod 16 has a protruding block 19 on one side. Every two adjacent folding blades 10 abut against each other through the block 19. The abutment of the block 19 forms a cavity 20 between every two adjacent push rods 17, reducing material consumption.

[0032] The support 2 is provided with a transverse slide rail 21 and a slider 22 that slides on the slide rail 21. The connecting plate 8 is fixed on the slider 22. The slider 22 is moved laterally by the extension and retraction of the cylinder, so as to realize the lateral movement of the folding knife mechanism 4 for folding. The support 2 is provided with two slide rails 21 and slider 22, which correspond to the lateral movement of the first folding knife assembly 6 and the second folding knife assembly 7, respectively.

[0033] The fixed plate 1 has a longitudinal slide rail 21 on the side near the support 3, and a sliding block 23 is provided on the side wall of the support 3. The sliding block 23 can slide up and down on the slide rail 21. The end of the drive motor 2 is provided with a gear 24, and the side wall of the support 3 is also provided with a rack 25 adapted to the gear 24. The gear 24 meshes with the rack, and the rack 25 is fixed to the support 3. The drive motor 2 drives the gear 24 to rotate, and the gear 24 drives the rack 25 to realize the up and down movement of the support 3. The gear 24 is a helical gear, which makes the operation more stable and has a higher load-bearing capacity.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
