[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to the accompanying drawings, in the embodiments of this implementation manner, the leather case forming production line includes a face paper feeding device 80, a face paper gluing device 81, a material conveying device 82 (such as a suction conveyor belt, etc.), and a cardboard and face paper positioning laminating device 83 (or a positioning machine, a cover mechanism, etc.). The face paper feeding device 80 is connected to the face paper gluing device 81, the face paper gluing device 81 is connected to the material conveying device 82, and the cardboard and face paper positioning laminating device 83 is connected to the conveying path of the material conveying device 82. The above are mature technologies and will not be elaborated here. In this implementation manner, the leather case forming production line further includes a leather case forming production device. The end of the conveying path of the material conveying device 82 is the feeding station 85 of the leather case forming production device. The material (i.e., the face paper and cardboard that are mutually adhered) waits at the feeding station 85 to enter the leather case forming production device.

[0033] Among them, the leather case forming production device includes a hemming device 1. The hemming device 1 includes a longitudinal side hemming component 10 and / or a transverse side hemming component 11. The hemming device 1 is a mature technology. For example, the relevant hemming and folding structures in various patent documents involved in the background technology. The corresponding hemming components can use hemming plates and / or hemming belts, etc. to cooperate to complete hemming and folding. The sequence of setting the longitudinal side hemming component 10 and the transverse side hemming component 11 can be set according to requirements.

[0034] In the present utility model, in order to smoothly complete the transverse side and / or longitudinal side hemming operations on the material with a special-shaped edge area at a local position on the transverse side and / or longitudinal side and ensure the hemming effect of the transverse side and / or longitudinal side, a local special-shaped edge hemming mechanism 2 is configured on the material input side of the hemming device 1. The feeding station 85 is set on the material input side of the local special-shaped edge hemming mechanism 2. The material output side of the local special-shaped edge hemming mechanism 2 is connected to the material input side of the hemming device 1. The local special-shaped edge hemming mechanism 2 includes a local special-shaped edge hemming component 20. The face paper at the local special-shaped edge is bent and wrapped around the edge part of the cardboard by the cooperation of the local special-shaped edge hemming component 20 (to complete the local special-shaped edge hemming). A local special-shaped edge hemming mechanism 2 is configured between the feeding station 85 and the hemming device 1. The local special-shaped edge hemming mechanism 2 cooperates to perform efficient and stable local hemming treatment on the special-shaped edge area at a local position on the transverse side and / or longitudinal side of the corresponding material. After completing the local special-shaped edge hemming first, the material is then conventionally hemmed by the hemming device 1 (for other areas of the transverse side and / or longitudinal side), and the leather case forming production can be smoothly completed. Among them, the local hemming treatment and the conventional hemming do not interfere with each other, avoiding mutual influence, avoiding the influence of the special-shaped edge area at a local position on the material on the conventional hemming forming production of the leather case (the entire transverse side and / or longitudinal side), and also avoiding the problem that the local special-shaped edge hemming cannot be smoothly completed when hemming and forming the leather case (the entire transverse side and / or longitudinal side). The overall hemming can be smoothly completed, ensuring the overall hemming effect.

[0035] The following optimization or further explanation may be performed based on the above embodiments.

[0036] The partial profiled edge wrapping mechanism 2 further includes a supporting platform 3, which can be used to support materials (cardboard and facial tissue) to cooperate with the partial profiled edge wrapping; the partial profiled edge wrapping component 20 is arranged at the edge of the supporting platform 3 to cooperate with the partial profiled edge wrapping; the partial profiled edge wrapping mechanism 2 further includes an edge wrapping execution drive device 4, which is transmission-connected to the partial profiled edge wrapping component 20, and the edge wrapping execution drive device 4 drives the partial profiled edge wrapping component 20 to run to cooperate with the profiled edge wrapping operation. For example, the partial profiled edge wrapping component 20 adopts a partial edge wrapping execution block.

[0037] There are many ways for the hemming execution driving device 4 to drive the hemming component 20 of the partial special-shaped edge to perform hemming operations, such as a combination of lifting and translation, and a parallelogram structure swing lifting method, etc. In the illustrated embodiment, the hemming execution driving device 4 includes a lifting driving component 40 and a translation driving component 41, which respectively drive the lifting and translation actions of the partial special-shaped edge hemming component 20, that is, up and down movement and left and right movement.

[0038] For example, in the figure, the partial special-shaped edge wrapping mechanism 2 also includes a lifting bracket 5, and the lifting drive component 40 is transmission-connected with the lifting bracket 5. The lifting drive component 40 drives the lifting bracket 5 to perform a lifting action. The lifting bracket 5 is provided with a transverse guide rail 50, and the transverse guide rail 50 is provided with two left and right transverse brackets 51. The transverse bracket 51 can move left and right (i.e., transversely) on the transverse guide rail 50. Each transverse bracket 51 is provided with a longitudinal adjustment rail 52, and the longitudinal adjustment rail 52 is provided with a longitudinal adjustment seat 53. The longitudinal adjustment seat 53 can not only move transversely with the transverse bracket 51, but also the longitudinal adjustment seat 53 can move longitudinally on the longitudinal adjustment rail 52 of the transverse bracket 51 to adjust the relative position. In order to meet the requirements of hemming of materials of different specifications and special-shaped edges at different positions, the local special-shaped edge hemming component 20 is arranged on the longitudinal adjustment seat 53, so that the special-shaped edge hemming component can move longitudinally and adjust the position with the longitudinal adjustment seat 53, and can also move horizontally with the transverse support 51; the translation drive component 41 is arranged on the lifting support 5, and the translation drive component 41 is connected with the transverse support 51 by transmission, and the transverse support 51 is driven by the translation drive component 41 to move horizontally; the local special-shaped edge hemming component 20 is distributed on the left and right sides of the supporting platform 3, and the supporting platform 3 can support the material, and the local special-shaped edge hemming component 20 cooperates to hem the special-shaped edge at the local position, and the left and right sides can cooperate with hemming according to the requirements. The structure has a reasonable layout, can be adjusted to meet the requirements of hemming of materials of different sizes and specifications, and meet the requirements of hemming of special-shaped edges at different positions. The structure is relatively compact, and the transverse guide rail 50 can not only be used for transverse movement (i.e. translation action) to cooperate with hemming, but also can be used for transverse adjustment to relatively meet the requirements of materials of different sizes and specifications.

[0039] The number of the partial special-shaped edge hemming components 20 can be set according to requirements. For example, when manufacturing a double-connected paper box cover (such as a wine box cover), two can be set on each of the left and right sides. Both of the two lid units in the double-connected paper box cover have inserting box tongue plate parts, and both sides of the inserting box tongue plate parts can be set as small inclined edges (i.e., partial special-shaped edges) to facilitate insertion into the paper box. When manufacturing the double-connected paper box cover, after hemming the small inclined edges with a total of four partial special-shaped edge hemming components 20 on the left and right, the longitudinal edges and transverse edges of the material can be subjected to subsequent overall longitudinal hemming and transverse hemming. Even during operation, only one of the lid units is subjected to special-shaped edge hemming, and the other lid unit is of a normal common shape (without small inclined edges and no special-shaped edge hemming is required), that is, some of the partial special-shaped edge hemming components 20 are in an idle state or a running state without hemming the material. For example, two longitudinal movement adjusting seats 53 are arranged front and back on each longitudinal adjusting guide rail 52, and corresponding partial special-shaped edge hemming components 20 are arranged on each longitudinal adjusting guide rail 52; the partial special-shaped edge hemming components 20 are rotationally adjusted and set on the longitudinal movement adjusting seats 53, so that the hemming angle can be adjusted to ensure more stable hemming, better hemming effect and tighter hemming; for example, a rotation adjusting support vertical shaft 54 is arranged on the longitudinal movement adjusting seat 53, and a rotation adjusting seat 55 is sleeved and locked (such as by a fastener locking method) on the rotation adjusting support vertical shaft 54, and the partial special-shaped edge hemming components 20 are installed and connected to the rotation adjusting seat 55, so as to replace and disassemble the partial special-shaped edge hemming components 20, and different partial special-shaped edge hemming components 20 can be selected to adapt to different special-shaped edge sizes and styles (such as inclined straight edges, curved edges, arc edges, concave edges, etc.); a material supporting platform 3 can be arranged between the two transverse movement brackets 51 on the left and right, which is convenient to set and has a simple structure.

[0040] In addition, the lifting drive component 40 may include a lifting drive motor 42 or a lifting drive cylinder, etc.; the translation drive component 41 may include a translation drive motor 44 or a translation drive cylinder, etc. In the figure, the lifting drive component 40 includes a lifting drive motor 42, and the lifting drive motor 42 is connected to the lifting bracket 5 through a first screw nut transmission mechanism 43, and the lifting path and stroke can be set according to the needs, which is convenient for control and has relatively high precision. A lifting guide rod 47 can also be configured to provide the lifting bracket 5 with stable lifting, and a lifting buffer spring can also be configured to make the lifting bracket 5 run more stably; the translation drive component 41 includes a translation drive motor 44, and the translation drive motor 44 is connected to the transverse bracket 51 through a second screw nut transmission mechanism 45, and the lifting path and stroke can be set according to the needs, which is convenient for control and has relatively high precision; the lifting drive motor 42 and the translation drive motor 44 can use servo motors, which are more accurate and efficient. Among them, the second screw nut transmission mechanism 45 includes a forward and reverse bidirectional screw 46, and the left and right lateral moving brackets 51 are connected to each other by the forward and reverse bidirectional screw 46, and the forward and reverse bidirectional screw 46 is connected to the translation drive motor 44. The translation drive component 41 cooperates with the second screw nut transmission mechanism 45 to drive the left and right lateral moving brackets 51 to move horizontally, which can not only be used for lateral movement (i.e., translational movement) to cooperate with hemming, but also can be used for lateral adjustment to relatively meet the requirements of materials of different sizes and specifications.

[0041] In the figure, the partial special-shaped edge wrapping parts 20 are distributed on the left and right sides, and the supporting platform 3 is between the partial special-shaped edge wrapping parts 20 on the left and right sides.

[0042] In addition to supporting the material to cooperate with edge wrapping, the material supporting platform 3 can also have the function of conveying the material. For example, the material supporting platform 3 includes a longitudinal material conveying belt 6 (a suction conveyor belt can be selected to increase the conveying stability). The longitudinal material conveying belt 6 is drivingly connected to a conveying drive motor 60, which is convenient for the material to be input and stay for local special-shaped edge wrapping, and for quickly outputting after edge wrapping, and is also convenient for the front and rear conveying connection. In addition, a material sensor 61 (such as a photoelectric eye) is provided above the longitudinal material conveying belt 6. The material conveyor is drivingly connected to the conveying drive motor 60, so as to receive the material incoming signal through the material sensor 61 and stop in time to ensure that the material is in place for accurate local special-shaped edge wrapping. In addition, a lifting and pressing component 62 (such as a lifting pressing plate, etc.) is provided above the longitudinal material conveying belt 6. The lifting and pressing component 62 is drivingly connected to a pressing drive component 63 (such as a cylinder or a motor, etc.). Pressing the material on the longitudinal material conveying belt 6 to stabilize its position and then performing local special-shaped edge wrapping on it will be more stable, avoiding displacement during the edge wrapping process and affecting subsequent operations. Even more, a lateral pushing and position correcting component 64 (such as a lateral pushing block or a lateral pushing plate, etc.) is provided on the left side and / or the right side of the longitudinal material conveying belt 6. The lateral pushing and position correcting component 64 is drivingly connected to a lateral pushing drive component 65 (such as a cylinder or a motor, etc.). The relative position of the material is corrected by lateral pushing to avoid inaccurate relative position of the material. Among them, the lifting and pressing component 62 and the lateral pushing and position correcting component 64 can be adjusted left and right according to requirements to meet different specifications. Further optimized, the longitudinal material conveying belt 6 can include a left conveyor belt 66 and a right conveyor belt 67. The left conveyor belt 66 is arranged on a left support 68, and the right conveyor belt 67 is arranged on a right support 69. The left support 68 and / or the right support 69 is arranged on a transverse guide rail 70, so that the distance between the left support 68 and the right support 69 can be adjusted to meet the conveying of different specifications of materials and supply the edge position for the operation of the local special-shaped edge wrapping component 20. Among them, the left support 68 and / or the right support 69 is drivingly connected to a transverse movement adjusting drive device 71 (such as a screw and nut mechanism with a motor, etc.). The left conveyor belt 66 and the right conveyor belt 67 can be respectively equipped with motors to drive the feeding operation, or can be driven by the same motor through a transverse spline shaft 72.

[0043] Of course, in addition to using the above-mentioned longitudinal material conveying belt 6 to cooperate with the material conveying, a manipulator can also be used to cooperate with the feeding. That is, the feeding station 85 and the local special-shaped edge wrapping mechanism 2 are connected in cooperation through belt feeding or through a manipulator with a lifting suction nozzle (such as an air nozzle) for feeding in cooperation.
