[0002] U-shaped cards are widely used in the field of gift box packaging to fold paper into specific shapes to achieve structural support and decorative effects for gift boxes. Traditionally, the manufacture of gift box packaging usually involves manual operations, including manual folding, positioning and assembly of paper sheets. This traditional manual operation method has a series of problems, such as low production efficiency, relatively high cost, and difficulty in ensuring the consistency of each product.

[0003] With the continuous development of automation technology, the industry gradually tends to adopt automated equipment to improve the production efficiency and product quality of gift box packaging. However, in the field of gift box packaging, folding is a key process in the traditional U-shaped card product manufacturing. The traditional manual folding method has problems such as unstable quality, low efficiency, and high cost. Although automated production lines are widely used in industry, there is no complete and efficient automated solution in the field of U-shaped card folding. Some existing equipment may face problems such as unsatisfactory folding effect, easy rebound, and low production efficiency when realizing U-shaped card folding, requiring more innovative and efficient solutions.

[0028] See also Figures 1 to 5 The present application first provides an embodiment of a U-shaped card folding and forming mechanism, the embodiment comprising:

[0029] The upper mold 011, the lower mold 012, the upper lifting cylinder 013, the lower lifting cylinder 014 and the clamping cylinder 015, the upper mold 011 is connected to the cylinder shaft of the upper lifting cylinder 013, the upper lifting cylinder 013 drives the upper mold 011 to move up and down, the lower mold 012 is connected to the cylinder shaft of the lower lifting cylinder 014, the clamping cylinder 015 is connected to the cylinder shaft of the lower lifting cylinder 014, the lower lifting cylinder 014 drives the lower mold 012 to move up and down, when folding, the clamping cylinder 015 drives the lower mold 012 to clamp the two sides of the U-shaped card, and the upper mold 011 cooperates with the lower mold 012 to extrude the U-shaped card into a U shape.

[0030] The embodiments are described in detail below:

[0031] Upper mold 011: Upper mold 011 is one of the key parts of the U-shaped card folding and forming mechanism. It is connected to the cylinder shaft of the upper lifting cylinder 013 and realizes up and down movement through the movement of the upper lifting cylinder 013. The shape and size design of the upper mold 011 matches the folding requirements of the U-shaped card.

[0032] Upper lifting cylinder 013: The upper lifting cylinder 013 is a power device for controlling the up and down movement of the upper mold 011. Through the cylinder shaft connection of the upper lifting cylinder 013, the upper lifting cylinder 013 can accurately control the position of the upper mold 011 to ensure the accuracy of the folding process.

[0033] Lower mold 012: Lower mold 012 is another key part of the U-shaped card folding and forming mechanism. It is connected to the cylinder shaft of the lower lifting cylinder 014 and realizes up and down movement through the movement of the lower lifting cylinder 014. The shape and size design of the lower mold 012 matches the folding requirements of the U-shaped card.

[0034] Lower lifting cylinder 014: The lower lifting cylinder 014 is a power device for controlling the up and down movement of the lower mold 012. Through the cylinder shaft connection of the lower lifting cylinder 014, the lower lifting cylinder 014 can accurately control the position of the lower mold 012 to ensure the accuracy of the folding process.

[0035] Clamping cylinder 015: Clamping cylinder 015 is a key component for clamping the U-shaped card during folding. Clamping cylinder 015 is connected to the cylinder shaft of lower lifting cylinder 014. Through the movement of lower lifting cylinder 014, clamping cylinder 015 drives lower mold 012 to clamp both sides of the U-shaped card to better complete the folding work, so that the U-shaped card is fully folded between upper mold 011 and lower mold 012.

[0036] Working process:

[0037] Before folding begins, the U-shaped card folding and forming mechanism is in an initial position. The upper mold 011 and the lower mold 012 are respectively located at predetermined positions, and the clamping cylinder 015 is in a released state.

[0038] First, the upper lifting cylinder 013 is started to move the upper mold 011 downward, providing space for the folding of the U-shaped card. After the upper mold 011 moves downward, the card can be fixed between the upper mold 011 and the lower mold 012, and then the lower mold 012 moves upward again to complete the folding of the card.

[0039] The clamping cylinder 015 is activated to clamp the two sides of the U-shaped card. This action ensures that the U-shaped card remains in a stable clamping state during the folding process.

[0040] The lower lifting cylinder 014 is started, causing the lower mold 012 to move upward, and the U-shaped card is gradually folded into a U shape under the coordinated action of the upper mold 011 and the lower mold 012.

[0041] When the upper mold 011 and the lower mold 012 are completely close together, the folding process is completed. The U-shaped card presents a "U" shape, and the clamping cylinder 015 releases the clamping, preparing to transfer the folded U-shaped card to the next workstation or assembly station.

[0042] Furthermore, in order to better complete the folding of the U-shaped card, the upper mold 011 can be provided with an inclined surface so that the flip angle of the U-shaped card when folded exceeds 90 degrees, so as to reserve a certain margin for the rebound of the card.

[0043] Specifically, a mold bottom surface 0111 is disposed at the bottom of the upper mold 011, and mold inclined surfaces 0112 are disposed on both sides. The upper ends of the mold inclined surfaces 0112 tend to approach each other, and the lower ends tend to move away from each other.

[0044] In this improved embodiment, the design of the upper mold 011 is further optimized to better complete the folding of the U-shaped card and reserve a certain margin for the rebound of the card. Specifically, the bottom of the upper mold 011 is provided with a mold bottom surface 0111, and mold inclined surfaces 0112 are provided on both sides. The design of the mold inclined surfaces 0112 has a tendency for the upper ends to approach each other and the lower ends to move away from each other.

[0045] In this embodiment, a flat mold bottom surface is provided at the bottom of the upper mold 011 to support the bottom of the U-shaped card to form a flat bottom edge during the folding process.

[0046] The mold slope 0112 is arranged on both sides of the upper mold 011, with the upper ends tending to approach each other and the lower ends tending to move away from each other. The upper ends of the mold slope tend to approach each other, so that during the folding process of the U-shaped card, the upper two sides gradually approach each other, forming an effect of a flip angle exceeding 90 degrees. This design helps to provide a reserve margin for the rebound of the card during the folding process.

[0047] The lower ends of the mold slopes 0112 tend to move away from each other. This design helps to ensure that after the U-shaped card is folded, the two sides of the bottom can be stably maintained at a certain distance to form a U shape.

[0048] The shape of the lower mold 012 can be consistent with that of the upper mold 011. Specifically, the lower mold 012 includes sub-molds 0120 arranged on both sides in a mirror-symmetrical manner. The bottom of the sub-mold 0120 is provided with a pressing bottom surface 0121, and the inner side is provided with a pressing inclined surface 0122. The pressing inclined surface 0122 is parallel to the mold inclined surface 0112, and the pressing bottom surface 0121 is parallel to the mold bottom surface 0111.

[0049] In this improved embodiment, the design of the lower mold 012 is consistent with the upper mold 011, including sub-molds 0120 arranged on both sides in mirror symmetry. The bottom of each sub-mold 0120 is provided with a pressing bottom surface, and the inner side is provided with a pressing inclined surface.

[0050] In this embodiment, the lower mold 012 is composed of two sub-molds 0120 arranged on both sides in a mirror-symmetrical manner, ensuring that the U-shaped card can be evenly stressed during the folding process.

[0051] The bottom of each sub-mold 0120 is provided with a flat pressed bottom surface, which is used to support the bottom of the U-shaped card to form a flat bottom edge during the folding process.

[0052] Each sub-mold 0120 is provided with a pressing inclined surface on its inner side, which is parallel to the mold inclined surface of the upper mold 011. This design helps to guide the upper part of the U-shaped card to gradually approach during the folding process to form a flip angle.

[0053] The pressing bottom surface is parallel to the bottom surface of the upper mold 011, and the pressing inclined surface is parallel to the inclined surface of the upper mold 011. Such a design ensures that the upper mold 011 and the lower mold 012 match each other, so that the U-shaped card can be stably stressed during the folding process, and ensures that the U-shaped card formed after folding has an accurate shape.

[0054] In an optional embodiment, it also includes a support structure 016, the upper lifting cylinder is fixed on the support structure 016, the support structure 016 is provided with a guide hole 017 and a guide column 018, the guide column 018 is arranged in the guide hole 017, and the upper mold 011 is connected to the support structure 016 through the guide column 018.

[0055] The support structure 016 in this optional embodiment provides additional support for the stability and accuracy of the U-shaped card folding and forming mechanism. By fixing the upper lifting cylinder on the support structure 016, the vertical movement of the upper mold 011 is achieved, and the structure of the guide column 018 and the guide hole 017 ensures the accurate guidance of the upper mold 011.

[0056] The support structure 016 is designed to enhance the stability of the upper lifting cylinder, so that the upper mold 011 moves more smoothly during the folding process of the U-shaped card, which effectively supports the implementation of the folding operation. The structure of the guide column 018 and the guide hole 017 not only makes the movement of the upper mold 011 more accurate, but also helps to reduce the vibration caused by unstable movement, thereby improving the working accuracy of the mechanism.

[0057] Furthermore, it also includes a connecting plate 019, and the upper mold 011 is fixed to the guide column through the connecting plate 019.

[0058] In this optional embodiment, a connecting plate 019 is introduced, which connects the upper mold 011 and the guide pillars, further enhancing the fixation and guidance of the upper mold 011. The connecting plate 019 serves as a connecting element, firmly connecting the upper mold 011 to the guide pillars, ensuring the stability and accuracy of the vertical movement of the upper mold 011.

[0059] The design of the connecting plate 019 not only enhances the fixation of the upper mold 011, but also has a fine-tuning function. By setting some adjustment devices on the connecting plate 019, such as adjusting bolts or other adjustable structures, a slight adjustment of the position of the upper mold 011 can be achieved. This fine-tuning design helps to finely adjust the U-shaped card folding and forming mechanism in actual operation to meet the folding needs of U-shaped cards of different specifications or requirements.

[0060] By introducing the design of the connecting plate 019 into the folding and forming mechanism, a more convenient fixing method can be provided for molds of various specifications. The existence of the connecting plate 019 makes the replacement or adjustment of the mold simpler and more flexible.

[0061] Different specifications of U-shaped cards may require molds of different shapes or sizes, and the design of the connecting plate 019 enables these molds to be easily connected to the guide pillars and to make slight position adjustments through the adjustable structure.

[0062] In the present application, there are multiple options for the number of clamping cylinders, for example, it can be 2, 3, 4, 5, 6, etc. When the lower mold 012 is composed of two sub-molds 0120, at least 2 groups of clamping cylinders can be provided, which are respectively arranged on the left and right sides of the lower mold 012, and are respectively connected to the sub-molds 0120 on the left and right sides.

[0063] In the folding and forming mechanism, by setting a plurality of clamping cylinders, the U-shaped card can be better fixed to ensure that no deviation or instability occurs during the folding process.

[0064] When the lower mold 012 is composed of two sub-molds 0120, at least two groups of clamping cylinders are provided, which are respectively connected to the left and right sides of the lower mold 012. The clamping cylinders respectively provided on the left and right sides can provide a balanced clamping force to ensure that the U-shaped card is subjected to uniform force when folding. Multiple groups of clamping cylinders can enhance the clamping stability of the U-shaped card and avoid shaking or instability during the folding process. The setting of multiple groups of clamping cylinders also improves the fault tolerance of the system. When a group of cylinders has a problem, the other groups can still maintain the clamping effect.

[0065] In an optional embodiment, a material dispensing slot plate 020 may be further provided, and a material dispensing slot 021 is provided on the material dispensing slot plate 020 . When folding, the lower lifting cylinder drives the lower mold 012 to extend out of the material dispensing slot 021 .

[0066] In practice, in order to better load the materials, a material-dispensing slot plate 020 may be provided, and the material-dispensing slot 021 on the material-dispensing slot plate 020 can provide a material-dispensing channel to ensure that the unformed U-shaped card is accurately placed in the folding area, providing a good starting point for the subsequent folding operation. Therefore, in order to prevent the formation of motion interference, after the loading is completed, that is, when the folding begins, the lower mold 012 is driven by the lower lifting cylinder to extend from the material-dispensing slot 021 to fold the U-shaped card.

[0067] In this embodiment, by folding after loading, the motion interference between the loading and folding processes is effectively avoided. This ensures that the U-shaped card will not be affected by other moving parts when folding, thereby improving the stability of the system.

[0068] The feeding channel is provided by the feeding trough plate 020, which ensures that the U-shaped card is accurately placed in the folding area. Before folding, the lower mold 012 extends from the feeding trough 021 through the lower lifting cylinder to fix the U-shaped card in the correct position, which helps to achieve accurate folding.

[0069] Furthermore, auxiliary cylinders 022 and auxiliary push blocks 023 are provided on both sides of the material dispensing groove 021. The auxiliary push blocks 023 are connected to the cylinder shafts of the auxiliary cylinders 022. When folding, the auxiliary cylinders 022 drive the auxiliary push blocks 023 to push the lower mold 012 for clamping.

[0070] In this further embodiment, during the folding process, the auxiliary cylinder 022 can drive the auxiliary push block 023 to push the lower mold 012 for clamping. Such a design can ensure that the U-shaped card is subjected to sufficient clamping force while folding, and prevent instability during the folding process.

[0071] The introduction of the auxiliary cylinder 022 helps to improve the clamping stability of the lower mold 012 on the U-shaped card, thereby ensuring the folding quality. Insufficient clamping may cause the U-shaped card to be incompletely folded or irregular in shape, and the introduction of the auxiliary push block 023 can effectively avoid these problems.

[0072] In an optional embodiment, a hollow portion 024 is provided on the upper mold 011 .

[0073] In this optional embodiment, by providing a hollow portion 024 on the upper mold 011, a folding space can be provided for the portion extending from the upper portion of the U-shaped card when the U-shaped card is folded, so that each portion of the U-shaped card can obtain a sufficient folding angle. The provision of the hollow portion 024 provides more folding space for the upper portion of the U-shaped card. This means that during the folding process, the upper portion of the U-shaped card can be folded more flexibly without being restricted by space, thereby ensuring that the shape of the entire U-shaped card can better meet the design requirements.

[0074] In an optional embodiment, at least two groups of lower lifting cylinders are provided, which are respectively connected to the sub-molds 0120 on both sides.

[0075] In the present application, there can be multiple options for the number of lower lifting cylinders, for example, it can be 2, 3, 4, 5, 6, etc. When the lower mold 012 is composed of two sub-molds 0120, at least 2 groups of lower lifting cylinders can be provided, which are respectively connected to the sub-molds 0120 on the left and right sides, for driving the sub-molds 0120.

[0076] In the folding and forming mechanism, by setting a plurality of lower lifting cylinders, the U-shaped card can be better fixed to ensure that no deviation or instability occurs during the folding process.
