DETAILED DESCRIPTION

[0037] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this solution.

[0038] Example 1

[0039] like Figures 1 to 10 As shown, this embodiment designs a fully automatic packaging box cover production line, including a shell material feeding line, a leather material feeding line, a cover molding line and a molding material discharging line.

[0040] The foreskin forming line is arranged vertically and can be installed on the forming mechanism 3 in Example 2. A downwardly movable magnetic punch head 311 is provided at the starting point of the foreskin forming line, and a forming base plate 38 is provided at the end of the foreskin forming line. A receiving groove that matches the molding material A3 is provided at the center of the molding base plate 38. As the shell material A1 moves downward against the leather material A2 and enters the receiving groove, the shell material A1 is wrapped around the shell material A1 to form the molding material A3.

[0041] The shell material feeding line is arranged horizontally and is used to convey the shell material A1. The shell material feeding line can be composed of a conveyor line and the shell material loading mechanism 2 of Example 3. The end of the conveyor belt 1 is connected to the material picking station of the shell material loading mechanism 2, so that the shell material loading mechanism 2 can grab the shell material A1 from the conveyor belt 1. The shell material feeding line is used to transfer the shell material A1 to the starting point of the foreskin forming line and install it on the magnetic punching head 311.

[0042] The leather material feeding line is arranged in a horizontal direction and can be provided on the leather material feeding mechanism 4 in embodiment 4. The leather material feeding line is used to transfer the leather material A2 to the middle part of the foreskin forming line, so that the shell material A1 is pushed into the receiving groove of the forming seat plate 38 during the downward movement of the shell material A2 to form the forming material A3.

[0043] The molding material discharge line can be set on the molding mechanism 3 in Example 2, and the molding material discharge line includes a translation section and a grabbing section. The molding seat plate 38 can move back and forth between the starting point and the end point of the translation section, and is grabbed by the discharge suction cup 36 of the grabbing section.

[0044] Example 2

[0045] like Figures 4 and 5 As shown, this embodiment designs a Figures 1 to 2 As shown, this embodiment designs a shell material feeding mechanism 2 of a fully automatic packaging box wrapping production line, which includes three stations: a material picking station, a heating station, and a transfer station. The material picking station is used to provide the shell material A1 to be grabbed to the shell material feeding mechanism 2. The shell material A1 can be transported to the material picking station by a structure such as a conveyor belt, so that the shell material feeding mechanism 2 can grab the shell material A1. A heating table 26 is provided at the heating station. When the shell material A1 is placed on the heating table 26, the heating table 26 can heat the shell material A1. An electric heating wire can be provided in the heating table 26 to achieve the heating of the shell material A1. The transfer station is used for the storage of shell material A1. The shell material A1 at the transfer station can be transferred outward by the transfer tray 210.

[0046] The three stations of material picking, heating and transfer are arranged in a straight line, which facilitates the transfer of shell material A1 between different stations. In addition, the three stations of material picking, heating and transfer are located at the same height, which facilitates the synchronous grasping of shell material A1 by different suction cups.

[0047] A first manipulator and a second manipulator are positioned on opposite sides of the heating station. The first manipulator comprises a first translation mechanism 21, a first lifter 22, and a shell material suction cup holder. The first lifter 22 is fixed to the movable end of the first translation mechanism 21. The shell material suction cup holder is fixed to the lifting end of the first lifter 22. The shell material suction cup holder is provided with a first suction cup 24 and a second suction cup 25, arranged one behind the other along the conveying direction of the shell material A1. The second manipulator comprises a second translation mechanism 27, a second lifter 29, and a tray holder 28. The second lifter 29 is fixed to the movable end of the second translation mechanism 27. The tray holder 28 is fixed to the lifting end of the second lifter 29. A transfer tray 210 is fixed to the tray holder 28.

[0048] The first translation mechanism 21 and the second translation mechanism 27 can both include a track mounting base, a translation cylinder, a horizontal track, and a horizontal slide. Compared to a mobile module structure, this can significantly reduce component costs. The horizontal track is mounted on the track mounting base, and the horizontal slide slides in engagement with the horizontal track. The cylinder is connected between the track mounting base and the horizontal slide and controls the horizontal movement of the horizontal slide. The first lifter 22 and the second lifter 29 can both utilize a lifting cylinder, thereby reducing component costs.

[0049] The top surfaces of the heating table 26 and the transfer tray 210 are both provided with grooves into which the shell material A1 fits, thereby facilitating the positioning and heating of the shell material A1. During the transfer process between the material removal station, the heating station, and the transfer station, the shell opening of the shell material A1 faces upward.

[0050] When the shell material loading mechanism 2 in this embodiment is in use, the working process is as follows: the first manipulator can grab the shell material A1 from the material picking station to the heating table 26 through the first suction cup 24, and the shell material A1 is heated by the heating table 26; while the first suction cup 24 grabs the shell material A1, the first manipulator can also grab the shell material A1 from the heating table 26 to the transfer tray 210 at the transfer station through the second suction cup 25. The first suction cup 24 and the second suction cup 25 grab synchronously, and the first manipulator can realize the transfer of two shell materials A1 with the same displacement action, that is, the shell material A1 is transferred between the material picking station and the heating station, and between the heating station and the transfer station, which can effectively improve the processing efficiency. After the transfer tray 210 receives the shell material A1, the second manipulator can transfer the shell material A1 at the transfer station outward by moving the transfer tray 210.

[0051] Example 3

[0052] like Figures 6 to 8 As shown, this embodiment designs a Figures 1 to 3 As shown, this embodiment designs a forming mechanism for a fully automatic packaging box wrapping production line. The forming mechanism is used to wrap the leather material around the shell material to form a forming material, thereby completing the wrapping operation. The forming mechanism includes components such as a magnetic punching head, a side pressure block group, a leather material carrier plate and a forming seat plate.

[0053] The forming mechanism is mounted above a tabletop supporting the machine; a horizontally slidable discharge slide is provided on the tabletop. A track frame is mounted on the supporting machine, and the discharge slide is slidably engaged with the track frame; the discharge slide can be controlled by a cylinder to slide in a horizontal longitudinal direction.

[0054] A discharge rotary cylinder and a discharge lift cylinder are installed at one end of the discharge slide's sliding track; the discharge lift cylinder is mounted on the discharge rotary cylinder's rotating shaft; a discharge rack is mounted on the discharge rotary cylinder's piston rod, and a discharge suction cup is installed on the discharge rack. The discharge suction cup is used to grab the molding material on the molding base plate and discharge the material. The specific process is as follows: the discharge rotary cylinder rotates the discharge rack to the side of the molding base plate, and the discharge lift cylinder controls the discharge suction cup to descend and then rise, causing the discharge suction cup to grab the molding material on the molding base plate. The discharge rotary cylinder rotates the discharge rack away from the molding base plate, and the discharge suction cup releases the molding material.

[0055] The side pressure block assembly, leather carrier plate, and other components are located at the other end of the discharge slide's sliding path. The forming base plate is embedded in the center of the discharge slide and moves horizontally with the slide to discharge the molded material. When the forming base plate moves directly below the side pressure block assembly and leather carrier plate, the molded material can be formed at the center of the forming base plate. When the forming base plate moves to the discharge rotary cylinder, the molded material on the forming base plate is removed by the discharge suction cup.

[0056] The forming base plate, side pressure block group, and leather carrier plate are arranged in an overlapping manner from bottom to top; a receiving groove matching the forming material is provided at the center of the forming base plate. A central hole is provided at the center of the side pressure block group for the leather and shell materials to pass through. The side pressure block group includes four extrusion blocks. When the shell material and the leather side pressure block group are in the center, the four extrusion blocks converge to form the central hole and simultaneously press the leather material against the side of the shell material. A die hole is also provided at the center of the leather carrier plate for the leather and shell materials to pass through; the die hole matches the shape of the shell material. When the shell material drives the leather material through the die hole, the leather material can be deformed and attached to the shell material.

[0057] The magnetic punching head is arranged above the leather carrier plate; the magnetic punching head can magnetically absorb the shell material, and the shape of the lower part of the magnetic punching head matches the shape of the inner cavity of the shell material to apply uniform force to the shell material; a permanent magnet is installed in the magnetic punching head; the magnetic force of the permanent magnet can be determined according to needs, but it is necessary to ensure that the shell material can be magnetically absorbed to the bottom of the magnetic punching head and will not fall off in the absence of external force. At the same time, it is also necessary to ensure that after the shell material and the leather material are squeezed into the accommodating cavity of the forming seat plate, the forming material can be separated from the magnetic punching head.

[0058] The magnetic punching head is controlled to rise and fall by a punching lifting cylinder. When the piston rod of the punching lifting cylinder extends downward, the magnetic punching head can be controlled to move downward, and then the shell material and leather material are pushed through the center of the leather material carrier plate and the side pressure block group, and pressed into the receiving groove to produce the molding material.

[0059] A leather pressing plate is provided above the leather carrier plate, and the leather pressing plate is raised and lowered by a plurality of pressing plate lifting cylinders. The center hole of the leather pressing plate matches the shape of the magnetic punching head, so that the magnetic punching head can pass through the center hole of the leather pressing plate; the leather pressing plate can be lifted and lowered vertically to press the leather on the leather carrier plate.

[0060] The working process of the forming mechanism in this embodiment is as follows: the shell material is installed on the lower end of the magnetic punching head, and the leather material with preset glue on the upper surface is laid on the upper surface of the leather carrier plate; the pressure plate lifting cylinder controls the leather pressure plate to move downward so that the leather pressure plate presses the edge of the leather material; the stamping lifting cylinder controls the magnetic punching head to move downward, and after the magnetic punching head drives the shell material through the leather pressure plate, the shell material and the leather material are offset, and then the leather material is pushed through the mold hole in the center of the leather carrier plate. During this process, the edge of the leather material gathers inward and adheres to the side of the shell material; when the magnetic punching head pushes the shell material and the leather material to move down to the center of the side pressure block group, the four extrusion blocks are squeezed and gathered inward by the extrusion cylinder, thereby pressing the leather material to the side of the shell material; after the four extrusion blocks move away from each other, the magnetic punching head pushes the shell material and the leather material to continue to move downward and enter the accommodating cavity of the forming seat plate, and the leather material is tightly attached to the bottom surface of the shell material, thereby forming a molding material. After the magnetic punching head, extrusion block, leather carrier and other components are reset, the molding material remains in the accommodating cavity; when the discharge slide slides along the horizontal longitudinal direction to the discharge suction cup, the discharge suction cup grabs the molding material and sends it out; after the leather carrier is reset and the above process is repeated, continuous production of molding material can be achieved.

[0061] In the above process, the magnetic punch head only needs a single lifting motion to complete the molding of the molding material, effectively improving production efficiency. Specifically, during the downward pressing process of the magnetic punch head, the shell material and leather material are squeezed into the accommodating cavity of the molding base plate, and in conjunction with the side pressure block group and leather material carrier plate, the molding material is formed in one go. In addition, during the process of discharging the molding material using the discharge slide, the shell material and leather material can be simultaneously loaded into the molding mechanism to complete the preparation work, further improving production efficiency.

[0062] Example 4

[0063] like Figures 9 and 10 As shown, this embodiment designs a leather material feeding mechanism 4 for a fully automatic packaging box wrapping production line, including a base 44, a material changing translation platform 45, a leather material lifting platform 46, a leather material manipulator and a lifting mechanism 48 and other components.

[0064] The material changing translation platform 45 is arranged above the base 44 and can slide in the horizontal longitudinal direction; the material changing translation platform 45 is connected to the base 44 at the corner through the material changing telescopic device 49. When the material changing telescopic device 49 moves, the material changing translation platform 45 can be controlled to slide along the horizontal longitudinal direction.

[0065] Two leather lifting platforms 46 are arranged side by side above the material-changing translation platform 45. As the material-changing translation platform 45 moves, the two leather lifting platforms 46 are alternately moved to the bottom of the leather manipulator. These leather lifting platforms 46 are used to hold vertically overlapping leather. When the leather manipulator has grabbed all the leather on one leather lifting platform 46, the other leather lifting platform 46 can be moved to the bottom of the leather manipulator, ensuring a continuous supply of leather.

[0066] A lifting mechanism 48 is mounted below the base 44. Its push rod is capable of vertical movement. When the push rod ascends, its upper end moves upward, passing through the base 44 and the re-material translation platform 45. It then lifts one of the leather lifting platforms 46 upward, facilitating the leather manipulator's grasping of the leather. When the push rod descends, its upper end moves downward to below the re-material translation platform 45, preventing it from interfering with the horizontal movement of the re-material translation platform 45.

[0067] The leather manipulator includes components such as a leather translation mechanism 41, a leather lifting mechanism 42 and a leather suction cup frame 43; the leather translation mechanism 41 is fixedly installed above the base 44, and the leather lifting mechanism 42 is installed at the moving end of the leather translation mechanism 41; the leather suction cup frame 43 is installed at the lifting end of the leather lifting mechanism 42; and a plurality of leather suction cups 411 are installed on the leather suction cup frame 43. The leather suction cup frame 43 is also provided with a visual sensor 410 and a plurality of leather suction cups 411, and the leather suction cups 411 are used to grab leather. The leather translation mechanism 41 and the leather lifting mechanism 42 can respectively control the leather suction cups 411 to move in the vertical direction and the horizontal direction to transfer the leather.

[0068] The leather material translation mechanism 41 includes a track mounting base, a translation cylinder, a horizontal track, and a horizontal slide. Compared to a mobile module structure, this significantly reduces component costs. The horizontal track is mounted on the track mounting base, and the horizontal slide slides in contact with the horizontal track. The cylinder is connected between the track mounting base and the horizontal slide and controls the horizontal movement of the horizontal slide. The leather material lifting mechanism 42 uses a lifting cylinder, thereby reducing component costs.

[0069] The leather lifting platform 46 has a leather placement area at its center, surrounded by multiple rod holes. Multiple limiting rods 47 are mounted on the material exchange translation platform 45. These rods 47 pass through corresponding rod holes and abut against the edges of the leather to limit the position of the leather. The rod holes are elongated, and the material exchange translation platform 45 has multiple elongated mounting holes. The limiting rods 47 can be installed at different positions within the mounting holes to adjust their position.

[0070] Guide vertical rods are provided at the four corners of the leather lifting platform 46 , the lower ends of the guide vertical rods are fixedly connected to the material changing translation platform 45 , and the leather lifting platform 46 is slidably matched with the guide vertical rods.

[0071] When the leather material feeding mechanism 4 in this embodiment is in use, the working process is as follows: the leather material manipulator grabs and delivers the leather material through the leather material suction cup 411. After the leather material at the top of the leather material lifting platform 46 is grabbed, the lifting mechanism 48 lifts the leather material lifting platform 46 to a certain distance to ensure that the leather material suction cup 411 can smoothly grab the leather material; when the leather material on one leather material lifting platform 46 is used up, the lifting mechanism 48 is lowered and the material changing telescopic device 49 is telescopically moved, thereby moving another leather material lifting platform 46 loaded with leather material to the bottom of the leather material manipulator, so that the leather material manipulator can grab the leather material again, and new leather material can be manually added to the idle leather material lifting platform 46. In the above process, the replacement and replenishment of leather material is achieved by linearly moving the material changing translation platform 45, which can avoid the influence of centrifugal force on the position of leather material and improve the loading progress of leather material; at the same time, the structure is simple, the cost is low, and it is suitable for promotion.

[0072] The above embodiments are merely examples for the purpose of illustrating the present invention clearly and are not intended to limit the embodiments. It is not necessary and impossible to enumerate all embodiments here. Obvious changes or modifications derived therefrom are still within the scope of protection of this technology.
