[0035] 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.

[0036] Referring to the accompanying drawings, the casing machine in the embodiments of this embodiment includes a facial tissue feeding lifting table 10, a facial tissue feeding device 11, a facial tissue gluing device 12, a suction conveyor belt 13, a cardboard and facial tissue positioning and pasting device 14, and a edge-wrapping mechanism 15. The facial tissue feeding lifting table 10 and the facial tissue gluing device 12 are connected by the facial tissue feeding device 11. The facial tissue feeding device 11 cooperates to feed the facial tissue into the facial tissue gluing device 12. The output end of the facial tissue gluing device 12 is connected to the suction conveyor belt 13. After the facial tissue is glued in the facial tissue gluing device 12, it is output onto the suction conveyor belt 13. The cardboard and facial tissue positioning and pasting device 14 and the edge-wrapping mechanism 15 are arranged on one side of the suction conveyor belt 13. The suction conveyor belt 13 carries the facial tissue to the cardboard and facial tissue positioning and pasting device 14. The cardboard and facial tissue positioning and pasting device 14 cooperates to place the cardboard on the facial tissue and glue them together to form a casing material. Then, the material is continuously conveyed by the suction conveyor belt 13 to the edge-wrapping mechanism 15. The edge-wrapping mechanism 15 and the suction conveyor belt 13 are connected by a feeding lifting and transferring manipulator 16. The feeding lifting and transferring manipulator 16 cooperates to feed the material on the suction conveyor belt 13 into the edge-wrapping mechanism 15; among them, the facial tissue feeding device 11 uses a feeder head, the facial tissue gluing device 12 includes a gluing roller, and the cardboard and facial tissue positioning and pasting device 14 includes a cardboard covering mechanism; this is a mature technology and will not be elaborated here.

[0037] In this embodiment, in order to improve the speed and efficiency, the edge-wrapping mechanism 15 (i.e., the edge-wrapping mechanism 15 of the casing machine) is optimized and improved.

[0038] The hemming mechanism 15 of the case making machine includes a first hemming device 3 and a second hemming device 4. The first hemming device 3 is used to hem the front and rear edges of the material (such as hemming the long edge), and the second hemming device 4 is used to hem the left and right edges of the material (such as hemming the short edge). A longitudinal feeding belt 5 is provided between the first hemming device 3 and the second hemming device 4, and the longitudinal feeding belt 5 cooperates to transfer the material whose front and rear edges are hemmed by the first hemming device 3 to the second hemming device 4 for subsequent (left and right) hemming. The first hemming device 3 includes a first hemming device 3 and a second hemming device 4. The side plate 31 and the longitudinally moving support plate 32, the first side plate 31 is arranged in a front-to-back pair, and the longitudinally moving support plate 32 is arranged in a front-to-back pair, that is, there are the first side plate 31 opposite to each other and the longitudinally moving support plate 32 opposite to each other, the first side plate 31 opposite to each other is used to cooperate in hemming the front and rear edges of the material (such as hemming the long edge), the first side plate 31 is arranged on the upper side of the corresponding longitudinally moving support plate 32, the first side plate 31 is a longitudinally moving side plate, that is, the first side plate 31 is located on the upper side of the corresponding longitudinally moving support plate 32 for longitudinal movement, and the longitudinally moving support plate 32 can also move longitudinally;

[0039] Among them, a material capacity spacing matching the material thickness is reserved between the first edge wrapping plate 31 and the longitudinally movable supporting plate 32 below, so that when the material (including facial tissue and cardboard) is placed on the longitudinally movable supporting plate 32, the first edge wrapping plate 31 can smoothly move longitudinally above the material to fold the facial tissue to cooperate with the edge wrapping; wherein, the front and rear first edge wrapping plates 31 are separated from each other to form a working position for upward tilting facial tissue, and the front and rear first edge wrapping plates 31 are spaced apart from each other to form a downward moving material feeding space. When in this working position, the material is pushed downward in the downward moving material feeding space between the front and rear first edge wrapping plates 31. Put it in, wherein the front and rear longitudinally movable support plates 32 can cooperate and operate at the front and rear edges of the lower side of the downwardly movable feeding space, and when the material (the cardboard with the face paper pasted on the lower side) is put in downward, the front and rear first edge wrapping plates 31 can bend the face paper at the edge of the cardboard upward at this working position; wherein the front and rear first edge wrapping plates 31 are close to each other to form a working position for folding the face paper in the middle, and after the material is put down into place, the first edge wrapping plates 31 are close to each other at this working position to fold the face paper that is tilted upward toward the middle (front and back) to complete the edge wrapping;

[0040] The front and rear longitudinal support plates 32 are close to each other to form a working position for supporting materials. When the material is put downward into the downward feeding space, the front and rear longitudinal support plates 32 will cooperate to smoothly receive and support the material at this working position. The material (including facial tissue and paperboard) will be placed on the longitudinal support plates 32 for subsequent hemming operations; the front and rear longitudinal support plates 32 are separated from each other to form a working position for unloading materials. In this working position, the front and rear longitudinal support plates 32 are in a state of being separated from each other, and can release (receive and support) the material to allow the material to move downward;

[0041] Among them, the longitudinal feeding belt 5 is arranged below the longitudinal moving material supporting plate 32. When the front and rear longitudinal moving material supporting plates 32 are in a separated state, the material can be released and moved downward, and the material can move downward onto the longitudinal feeding belt 5. Then, the longitudinal feeding belt 5 cooperates to send the material to the second edge wrapping device 4 for edge wrapping and directly output after the edge wrapping is completed; a lower feeding device 6 is also arranged between the longitudinal feeding belt 5 and the longitudinal moving material supporting plate 32. The lower feeding device 6 cooperates to convey the material downward, and the material is stably and accurately moved downward onto the longitudinal feeding belt 5 to avoid problems such as unstable position deviation. The lower feeding device 6 cooperates with the longitudinal feeding belt 5 to transfer the material from the first edge wrapping device 3 to the second edge wrapping device 4;

[0042] Among them, the second edge wrapping device 4 includes second edge wrapping plates 41. The second edge wrapping plates 41 are arranged in a left-right paired manner, that is, there are second edge wrapping plates 41 opposite to each other left and right. The second edge wrapping plates 41 opposite to each other left and right are used to cooperate in edge wrapping the left and right edges of the material (such as short edge wrapping); the second edge wrapping plates 41 are arranged on the outer sides of the longitudinal feeding belt 5. The left and right middle positions are the inner sides, and the left and right sides are the outer sides. For example, the left second edge wrapping plate 41 is located at the left side position beside the longitudinal feeding belt 5, and the right second edge wrapping plate 41 is located at the right side position beside the longitudinal feeding belt 5.

[0043] The working principle is as follows: After the face paper is fed in the case making machine (or called the case making machine), it is sent for gluing. After gluing, the face paper is carried by the suction conveyor belt 13 and positioned and pasted with the cardboard to form the case material. Then, the feeding lifting and transferring manipulator 16 lifts the case material on the suction conveyor belt 13, rises and transfers it to the designated position, and then descends and discharges it into the first edge wrapping device 3. This is a mature technology and will not be elaborated.

[0044] The working principle of the hemming mechanism 15 of the case making machine is as follows: the material put into the lower feeding space is lifted up by the separated front and rear first hemming plates 31, and no additional operation is required for the first hemming plates 31 at this time; when the material is put into place, the front and rear longitudinally movable supporting plates 32 are brought together to support the material above; then, the front and rear first hemming plates 31 are brought together to fold the upwardly lifted hemming paper toward the middle (front and back), and the hemming (front and back edges) is completed, and the front and rear first hemming plates 31 can be separated and returned to their positions in time to wait for the next feeding; then, the front and rear longitudinally movable supporting plates 32 are separated from each other. In the open state, the material can be released (the supported material) and moved downward (after the downward movement is completed, the front and rear longitudinal support plates 32 move back to their original positions to wait for the next feeding). At this time, the new material to be edged can be prepared to be placed in the downward feeding space, which is relatively more efficient. The front and rear longitudinal support plates 32 are in a separated state from each other, and can release (the supported material) and move downward. The material is transported downward by the downward feeding device 6, and the material moves stably and accurately downward to the longitudinal feeding belt 5, so that the downward feeding device 6 cooperates with the longitudinal feeding belt 5 to transfer the material from the first edge wrapping device 3 to the second edge wrapping device 4.

[0045] In the case machine, the structure of the hemming mechanism 15 of the case machine is optimized to make the hemming mechanism 15 of the case machine more efficient. After the material is hemmed (front and rear edges) in the first hemming device 3, the material will be directly moved down to the longitudinal feeding belt 5, and moved by the longitudinal feeding belt 5 to the second hemming device 4 to complete the hemming (left and right edges), which does not affect the feeding of the first hemming device 3 from above, and is more efficient and relatively faster; and when the material is put into the first hemming device 3 downward, the front and rear first hemming plates 31 can directly lift the front and rear surface paper parts of the material to be hemmed upward, and only the front and rear first hemming plates 31 need to be moved longitudinally (towards the middle direction) to complete the hemming of the material (front and rear edges). The first hemming plate 31 and the longitudinal support plate 32 in the first hemming device 3 both adopt the corresponding longitudinal linear movement direction, which is simpler, more stable and more efficient. In the process of material feeding and final output, the material does not need to be withdrawn, and the material transportation is more efficient, which helps to improve efficiency and the overall hemming speed. More objects can be processed in the same time unit and more skins can be produced, which helps to reduce production costs.

[0046] The following optimization or further explanation may be performed based on the above embodiments.

[0047] For example, a lower feeding space is configured with a feeding lifting and transferring manipulator 16, and the feeding lifting and transferring manipulator 16 cooperates to place the material into the lower feeding space. For instance, the feeding lifting and transferring manipulator 16 includes a lifting suction and release nozzle 17. The lifting suction and release nozzle 17 cooperates to suck and hold the material, lift it, transfer it, and then release the material after descending. There are many and relatively mature methods, and industrial robots can be used for cooperation. The feeding lifting and transferring manipulator 16 can also have a pressing block 18 move together with the lifting suction and release nozzle 17. The pressing block 18 can cooperate to press the material so that it is more stable and flat when placed on the longitudinal transfer supporting plate 32. Corresponding lifting suction and release nozzles 17 and pressing blocks 18 are distributed and arranged on the transfer frame of the feeding lifting and transferring manipulator 16.

[0048] It can be further optimized. The first edge - wrapping plate 31 is installed on the longitudinal moving slide 33, and different sizes and specifications of the first edge - wrapping plate 31 can be replaced to adapt to the material specification requirements or edge - wrapping shape requirements. The longitudinal moving slide 33 is configured on the longitudinal track 34 and runs stably. In addition, the frame of the edge - wrapping mechanism 15 is provided with a front support 35 and a rear support 36. The front support 35 and the rear support 36 can respectively adopt flat plates. Corresponding first edge - wrapping plates 31 and longitudinal transfer supporting plates 32 are provided on both the front support 35 and the rear support 36. That is, the front and rear first edge - wrapping plates 31 are respectively arranged on the front support 35 and the rear support 36, and the front and rear longitudinal transfer supporting plates 32 are respectively arranged on the front support 35 and the rear support 36. A support longitudinal position - adjusting device 37 is provided between the rear support 36 and the frame. The rear support 36 is adjusted by the support longitudinal position - adjusting device 37 (such as including a longitudinal guide rail) to adjust its longitudinal relative position on the frame, so that the distance between the rear support 36 and the front support 35 is adjusted, realizing the adjustment of the distance between the front and rear first edge - wrapping plates 31 and the adjustment of the distance between the front and rear longitudinal transfer supporting plates 32 to meet the requirements of different material sizes and specifications. The front support 35 and the rear support 36 are respectively provided with an edge - wrapping longitudinal driving component 38 and a material - supporting longitudinal driving component 39. The edge - wrapping longitudinal driving component 38 cooperates to drive the first edge - wrapping plate 31 to move back and forth longitudinally. The edge - wrapping longitudinal driving component 38 can adopt a cylinder or a motor (such as a servo motor), etc. For example, the edge - wrapping longitudinal driving component 38 includes a motor 380 (such as a servo motor) driving a main shaft 381 to rotate back and forth. An eccentric wheel 382 is provided on the main shaft. The eccentric wheel drives the first edge - wrapping plate 31 to move back and forth longitudinally through a connecting rod 383. Both ends of the connecting rod are respectively hinged to the eccentric wheel and the first edge - wrapping plate 31, which is relatively more efficient. The distance extended during the longitudinal movement of the edge - wrapping can be adjusted by the rotation angle range of the main shaft back and forth, which is more convenient. The material - supporting longitudinal driving component 39 drives the longitudinal transfer supporting plate 32 to move back and forth longitudinally. The material - supporting longitudinal driving component 39 can adopt a cylinder or a motor (such as a servo motor), etc. For example, a cylinder is used in the figure.

[0049] For example, the downward feeding device 6 includes a lifting seat 60, a material supporting bearing component 61 and a material pressing clamping swing arm 62, the material pressing clamping swing arm 62 is hinged on the lifting seat 60 (its hinge shaft 67 can be arranged longitudinally front and back to form a swinging and rotating support structure), the material pressing clamping swing arm 62 can swing on the lifting seat 60, the material supporting bearing component 61 is arranged on the lifting seat 60, and the material supporting bearing component 61 is used to cooperate in supporting the bearing material, and they (the material pressing clamping swing arm 62, the material supporting bearing component 61) can move up and down together with the lifting seat 60, wherein the lifting and lowering of the lifting seat 60 can be driven by the lifting transmission structure 66, such as the lifting and lowering The transmission structure 66 includes a cylinder or a driving shaft with a gear rack 69 for transmission, etc., and a vertical guide rail 68 can be configured to provide a stable lifting action for the lifting seat 60; wherein, the pressure clamping and releasing swing arm 62 is configured on the outside of the longitudinal feeding belt 5, and the supporting material bearing component 61 is configured on the outside of the longitudinal feeding belt 5 to avoid interfering with the feeding, the left and right middle positions are the inner sides, and the left and right sides are the outer sides (the same below), for example, the left pressure clamping and releasing swing arm 62 and the supporting material bearing component 61 are located on the left side of the longitudinal feeding belt 5, and the right pressure clamping and releasing swing arm 62 and the supporting material bearing component 61 are located on the right side of the longitudinal feeding belt 5. The material pressing and clamping swing arm 62 is provided with a material pressing portion 63, which swings and rises and falls on the lifting seat 60 with the material pressing and clamping swing arm 62, so that the material pressing portion 63 cooperates with the material supporting member 61 to clamp the material; for example, when the material pressing and clamping swing arm 62 swings down toward the material supporting member 61, the material pressing portion 63 will press on the material supporting member 61 to clamp the material, and after clamping the material, the lifting seat 60 can be lowered to cooperate with the downward movement of the material feeding, and when the front and rear longitudinally moving supporting plates 32 are separated from each other, the downward moving feeding device 6 (such as its pressing The material pressing part 63, etc.) cooperates to receive and clamp the material and move it downward to the longitudinal feeding belt 5; for example, when the material pressing and clamping swing arm 62 moves away from the material supporting part 61 and swings upward, the material pressing part 63 separates from the material supporting part 61 and cooperates to release the material. After the downward feeding device 6 (such as its material pressing part 63, etc.) cooperates to receive and clamp the material and move it downward to the longitudinal feeding belt 5, the downward feeding device 6 (such as its material pressing part 63, etc.) can release the material, and then the lifting seat 60 rises again to wait for the next work (downward feeding). Among them, the material supporting component 61 has an ascending high position state and a descending low position state, that is, the material supporting component moves up and down with the lifting seat 60 to form high and low position states; when in the ascending high position state, the material supporting surface of the material supporting component 61 is lower than or flush with the material supporting surface of the longitudinal moving supporting plate 32, ensuring stable transition and receiving of materials; when in the descending low position state, the material supporting surface of the material supporting component 61 is lower than or flush with the feeding surface of the longitudinal feeding belt 5, ensuring that the material is stably placed on the longitudinal feeding belt 5.

[0050] The blank holder release swing arm 62 is drivingly connected with a reciprocating swing driving member 64 (such as including an air cylinder or a motor, in the figure, the air cylinder is connected between the blank holder release swing arm 62 and the lifting seat 60, and the piston rod 641 of the air cylinder is hinged to one end of the blank holder release swing arm 62). The reciprocating swing driving member 64 is arranged on the lifting seat 60, and the blank holder release swing arm 62 is driven by the reciprocating swing driving member 64 to reciprocate and swing on the lifting seat 60.
