[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the implementation mode of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

The output end of the tissue paper gluing device 12 is connected to the suction conveyor belt 13. After the tissue paper is glued by the tissue paper gluing device 12, it is output to the suction conveyor belt 13. The cardboard and tissue paper positioning pasting device 14 and the edge wrapping mechanism 15 are connected and arranged on one side of the suction conveyor belt 13, and the suction conveyor belt 13 is connected. The conveyor belt 13 carries the facial paper to the cardboard and facial paper positioning and pasting device 14, and the cardboard and facial paper positioning and pasting device 14 cooperate to place the cardboard on the facial paper and glue it to form a skin material. Then the material is continuously conveyed by the suction conveyor belt 13 to the edge wrapping mechanism 15, and the edge wrapping mechanism 15 and the suction conveyor belt 13 are connected by a feeding, lifting and transferring robot 16, and the feeding, lifting and transferring robot 16 cooperates to feed the material on the suction conveyor belt 13 into the edge wrapping mechanism 15; wherein, the facial paper feeding device 11 adopts a feeder head paper feeder, the facial paper gluing device 12 includes a gluing roller, and the cardboard and facial paper positioning and pasting device 14 includes a cardboard cover mechanism; this is a mature technology and will not be repeated.

[0030] In this embodiment, in order to improve the speed efficiency, the edge binding mechanism 15 (ie, the edge binding mechanism 15 of the case making machine) is optimized and improved.

[0031] 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; 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; 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; Among them, the longitudinal feeding belt 5 is arranged below the longitudinal moving supporting plate 32. When the front and rear longitudinal moving supporting plates 32 are in a mutually separated state, the material can be released to move downward, and the material can move downward to the longitudinal feeding belt 5, and then the longitudinal feeding belt 5 cooperates to send the material to the second edge wrapping device 4 for cooperation in edge wrapping and direct output after the edge wrapping is completed; a downward feeding device 6 is also arranged between the longitudinal feeding belt 5 and the longitudinal moving supporting plate 32, and the downward feeding device 6 cooperates to move the material downward and transport it, so that the material moves downward stably and accurately to the longitudinal feeding belt 5, avoiding problems such as position offset and instability, and 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; Among them, the second edging device 4 includes a second edging plate 41, and the second edging plate 41 is arranged in pairs on the left and right, that is, it has left and right opposite second edging plates 41, and the left and right opposite second edging plates 41 are used to cooperate in edging the left and right sides of the material (such as short side edging); the second edging plate 41 is arranged on the outside 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 edging plate 41 is located on the left side of the longitudinal feeding belt 5, and the right second edging plate 41 is located on the right side of the longitudinal feeding belt 5.

[0032] The working principle is: after the surface paper is fed into the shell machine (or shell machine), it is sent for gluing. After the gluing is completed, the paper is carried by the suction conveyor belt 13 and positioned and pasted with the cardboard to form the shell material. After that, the feeding, lifting and transferring robot 16 lifts the shell material on the suction conveyor belt 13 and transfers it to the position, and then lowers it to discharge it into the first edge wrapping device 3. This is a mature technology and will not be elaborated.

[0033] 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.

[0034] 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.

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

[0036] For example, the feeding, lifting and placing transfer robot 16 is configured in the downward feeding space, and the feeding, lifting and placing transfer robot 16 cooperates to place the material into the downward feeding space. For example, the feeding, lifting and placing transfer robot 16 includes a lifting suction and release nozzle 17, and the lifting suction and release nozzle 17 cooperates to suck the material and lift it, and then releases the material after transfer. There are many ways and they are more mature, and industrial robots can be used for cooperation and operation. The feeding, lifting and placing transfer robot 16 can also move the pressing block 18 together with the lifting suction and release nozzle 17. The pressing block 18 can cooperate with the pressurized material to make it more stable and flat when placed on the longitudinal moving support plate 32, wherein the corresponding lifting suction and release nozzles 17 and pressing blocks 18 are correspondingly distributed on the transfer frame of the feeding, lifting and placing transfer robot 16.

[0037] It can be further optimized, the first edging plate 31 is installed on the longitudinal slide 33, and the first edging plates 31 of different sizes can be replaced to adapt to material specification requirements or edging shape requirements, wherein the longitudinal slide 33 is configured on the longitudinal track 34 and runs stably. In addition, a front bracket 35 and a rear bracket 36 are provided on the frame of the edging mechanism 15. The front bracket 35 and the rear bracket 36 can be respectively flat plates. The front bracket 35 and the rear bracket 36 are both provided with corresponding first edging plates 31 and longitudinal support plates 32, that is, the front and rear first edging plates 31 are respectively arranged on the front bracket 35 and the rear bracket 36, and the front and rear longitudinal support plates 32 are respectively arranged on the front bracket 35 and the rear bracket 36. A bracket longitudinal adjustment device 37 is provided between the rear bracket 36 and the frame. The rear bracket 36 is adjusted in its longitudinal relative position on the frame by the bracket longitudinal adjustment device 37 (such as including a longitudinal guide rail), so that the distance between the rear bracket 36 and the front bracket 35 is adjusted, so as to realize the adjustment of the distance between the front and rear first edging plates 31 and the adjustment of the distance between the front and rear longitudinal support plates 32, so as to meet the requirements of different material size specifications. The front bracket 35 and the rear bracket 36 are respectively provided with an edge-wrapping longitudinal movement driving component 38 and a material-supporting longitudinal movement driving component 39, and the edge-wrapping longitudinal movement driving component 38 cooperates to drive the first edge-wrapping plate 31 to move back and forth longitudinally. The edge-wrapping longitudinal movement driving component 38 can adopt a cylinder or a motor (such as a servo motor), etc.; for example, the edge-wrapping longitudinal movement driving component 38 includes a motor 380 (such as a servo motor) to drive the main shaft 381 to rotate back and forth, and an eccentric wheel 382 is provided on the main shaft. The eccentric wheel moves back and forth longitudinally with the first edge-wrapping plate 31 through a connecting rod 383, and the two ends of the connecting rod are respectively hinged on the eccentric wheel and the first edge-wrapping plate 31, which is relatively more efficient. The extension distance of the edge-wrapping longitudinal movement can be adjusted by the back-and-forth rotation angle range of the main shaft, which is more convenient; the material-supporting longitudinal movement driving component 39 will drive the longitudinal movement of the material-supporting plate 32 to move back and forth longitudinally. The material-supporting longitudinal movement 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.

[0038] 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.

[0039] The press clamp release swing arm 62 is transmission-connected with a reciprocating swing driving component 64 (such as a cylinder or a motor, in the figure, the cylinder is connected between the press clamp release swing arm 62 and the lifting seat 60, and the cylinder piston rod 641 is hinged at one end of the press clamp release swing arm 62). The reciprocating swing driving component 64 is arranged on the lifting seat 60, and the reciprocating swing driving component 64 cooperates to drive the press clamp release swing arm 62 to swing back and forth on the lifting seat 60. For example, after further optimization, the pressing part 63 adopts a pressing roller, and the supporting member 61 includes a sponge pad, which clamps the material stably and is not easy to damage the material. After the material falls on the longitudinal feeding belt 5, the material can be directly dragged to move longitudinally without waiting for the pressing clamping swing arm 62 to reset and swing to separate the pressing part 63 from the supporting member 61, which is faster and easier to speed up. In addition, the pressing clamping swing arm 62 is also provided with a feeding auxiliary pressing wheel 65, which is located on the side of the pressing part 63. The feeding auxiliary pressing wheel 65 rises and falls and swings with the pressing clamping swing arm 62, and can cooperate with the downward feeding. The feeding auxiliary pressing wheel 65 cooperates to press the material on the longitudinal feeding belt 5.
