[0031] Figure 1 The three-dimensional structure diagram of the enclosure forming device of the embodiment of the present application. The enclosure forming device shown in the figure is used to fold and form the enclosure, and through the first forming mechanism 300, the second forming mechanism 400 and the forming die head 21, the enclosure paper blank is folded and formed into the enclosure, and the adhesive paper set at the tail end of the enclosure paper blank is folded and glued to the head end of the enclosure paper blank, so that the enclosure folding and gluing processing are completed at one station.

[0032] See also Figures 1 to 5 The frame forming device of the embodiment of the present application includes a bottom plate 100, on which a pressing die head mechanism 200, a first forming mechanism 300, a second forming mechanism 400 and a pushing mechanism 500 are provided. The pushing mechanism 500 is arranged on the longitudinal front side of the pressing die head mechanism 200, and the first forming mechanism 300 and the second forming mechanism 400 are arranged on the lateral sides of the pushing mechanism 500 and are arranged opposite to each other, wherein,

[0033] The pressing die mechanism 200 includes a forming die 21 . When the forming die 21 is driven to move vertically downward, it presses down the surrounding paper blank supported by the first forming mechanism 300 and the second forming mechanism 400 , and presses the surrounding paper blank downward to be supported by the lifting mechanism 500 .

[0034] In the present embodiment, the forming die 21 is used as a forming die for folding and forming the frame paper blank, that is, the outer shape of the forming die 21 matches the shape of the frame, and it also serves as a fixture for carrying and transferring the frame; it can be understood that a notch for folding the frame paper blank is cut and formed on the frame paper blank, and the cardboard area between two adjacent notches is a side wall of the frame and corresponds to an outer side wall of the forming die 21. After the frame paper blank is transferred to the forming station between the first forming mechanism 300 and the second forming mechanism 400, the bottom end of the forming die 21 is aligned with a cardboard area on the frame paper blank and presses the frame paper blank downward, and the head and tail ends of the frame paper blank are respectively placed on the first forming mechanism 300 and the second forming mechanism 400, and the frame paper blank is subjected to downward pressure and folded along the notch. At this time, the head and tail ends of the frame paper blank are in a V-shaped folded shape.

[0035] After the forming die 21 presses the frame paper blank down to be supported by the lifting mechanism 500, the first forming mechanism 300 and the second forming mechanism 400 cooperate with the forming die 21 to fold the frame paper blank into a frame, and fold the adhesive paper set at the tail end of the frame paper blank and glue it to the head end of the frame paper blank to fix the formed frame.

[0036] In this embodiment, when the forming die 21 is pressed down to a preset position, that is, after being placed on the pushing mechanism 500, the first forming mechanism 300 and the second forming mechanism 400 move toward each other and push the head and tail ends of the frame paper blank, and fold the cardboard areas on the left and right sides (corresponding to the lateral direction) of the forming die 21, so that each cardboard area of ​​the frame paper blank is correspondingly close to an outer side wall corresponding to the forming die 21, until the head and tail ends of the frame paper blank are facing each other and the adhesive paper is turned over to be directly above the head end of the paper blank, after which the frame forming mechanism 300 continues to move, folds the adhesive paper (folds the adhesive paper to the part directly above the head end of the paper blank) and glues it to the head end of the paper blank, so as to glue the head and tail ends of the frame paper blank and form it into a frame.

[0037] In the above-mentioned frame forming device, a pressing die head mechanism 200, a first forming mechanism 300, a second forming mechanism 400 and a pushing mechanism 500 are arranged on the bottom plate 100. When the forming die head 21 of the pressing die head mechanism 200 is driven to move vertically downward, the frame paper blank supported by the first forming mechanism 300 and the second forming mechanism 400 is pressed down, and the frame paper blank is pressed down to be supported by the pushing mechanism 500; after the forming die head 21 presses the frame paper blank down to be supported by the pushing mechanism 500, the first forming mechanism 300 and the second forming mechanism 400 are pressed down. The forming mechanism 300, the second forming mechanism 400 and the forming die head 21 fold the frame paper blank into a frame and fold the adhesive paper arranged at the tail end of the frame paper blank and glue it to the head end of the frame paper blank to fix the formed frame. The frame folding and gluing process can be completed at one workstation. The folded and formed material can be smoothly transferred to the next workstation without loosening, thereby ensuring the quality of the formed frame. This solves the problem that the frame forming device cannot perform forming and gluing at one time, causing the frame to loosen during the transfer process.

[0038] In order to realize the vertical movement of the transmission forming die head 21, the paper blank of the pressing frame is pressed onto the lifting mechanism 500, referring to Figures 1 to 5 In some embodiments, the pressing die mechanism 200 also includes a supporting seat 22 arranged on the base plate 100, and a first linear guide 23 extending vertically is provided on the side wall of the supporting seat 22, and the first linear guide 23 is slidably connected to a supporting slide 24, and a molding die 21 is installed at one end of the supporting slide 24 away from the sliding connection with the first linear guide 23, and a first driving unit 25 drivingly connected to the supporting slide 24 is also provided on the side wall of the supporting seat 22, wherein the first driving unit 25 is used to drive the supporting slide 24 to move along the first linear guide 23 to drive the molding die 21 to move vertically.

[0039] In some of the optional embodiments, the first drive unit 25 that drives the support slide 24 to move along the first linear guide rail 23 meets the first drive unit 25 of the embodiment of the present application. For example, the first drive unit 25 can be any one of an electric cylinder slide, a linear motor slide, and a linear screw slide, but is not limited to one of them.

[0040] In order to realize the shaping of the frame, refer to Figures 1 to 5In some embodiments, the first molding mechanism 300 and the second molding mechanism 400 both include a mounting seat 31, the mounting seat 31 is provided with a second linear guide rail 32 extending laterally, the first molding mechanism 300 corresponding to the second linear guide rail 32 is provided with a first folding knife 33 that can slide along the corresponding second linear guide rail 32, the second molding mechanism 400 corresponding to the second linear guide rail 32 is provided with a second folding knife 41 that can slide along the corresponding second linear guide rail 32, the first folding knife 33 and the second folding knife 41 are both connected to the second drive unit 34 installed on the corresponding mounting seat 31. Dynamic connection, wherein, after the forming die 21 presses the frame paper blank down to be supported by the lifting mechanism 500, the first folding knife 33 and the second folding knife 41 are respectively driven by the corresponding second driving unit 34 to move toward each other, and the first folding knife 33 and the second folding knife 41 push the head and tail ends of the frame paper blank toward the outer wall of the forming die 21 during the movement towards each other, so as to fold the frame paper blank into a frame; the second folding knife 41 is also driven to move toward the first folding knife 33 after completing the frame forming, so as to fold the adhesive paper set at the tail end of the frame paper blank and glue it to the head end of the frame paper blank.

[0041] In some optional embodiments, the second drive unit 34 includes one of the following: an electric cylinder slide, a linear motor slide, and a linear screw slide.

[0042] In this embodiment, the two first folding knives 33 and the second folding knives 41 are arranged opposite to each other in the transverse direction and are folding knives of two different shapes. The second folding knife 41 is a folding knife with an oblique wedging blade, and the first folding knife 33 is a folding knife with a groove-shaped blade engaged with the oblique wedging blade. When the first folding knife 33 is engaged with the second folding knife 41, the first folding knife 33 and the second folding knife 41 can push the frame paper blank flat to the point where the head and tail ends of the frame paper blank are aligned, and fold the adhesive paper to the top of the head end of the frame paper blank. In the process of the first folding knife 33 approaching the second folding knife 41, The groove-shaped blade avoids the forming die 21, that is, during the process of the first folding knife 33 and the second folding knife 41 biting and closing together, the first folding knife 33 will not be blocked by the forming die 21 due to the existence of the groove-shaped blade. At the same time, the second folding knife 41 will not be blocked by the forming die 21 because its oblique wedging surface is parallel to the oblique surface of the outer wall corresponding to the forming die 21. In this way, the first folding knife 33 and the second folding knife 41 cooperate with the outer wall of the forming die 21 to form the frame paper blank into a frame and glue the head and tail ends of the paper blank with adhesive paper.

[0043] In this embodiment, after the first forming mechanism 300 and the second forming mechanism 400 complete the forming of the frame paper blank, the two second driving units 34 drive the first folding knife 33 and the second folding knife 41 to move respectively, and the first folding knife 33 and the second folding knife 41 move away from each other and form a forming notch directly above the lifting mechanism 500. At this time, another new frame paper blank to be formed is placed on the first folding knife 33 and the second folding knife 41. At the same time, the corresponding forming die 21 is already above the new frame paper blank, and the lifting mechanism 500 is driven to a preset position. Thereafter, the forming die 21 moves vertically downward, and the first folding knife 33 and the second folding knife 41 are driven toward each other and engage with each other, thereby forming the new frame paper blank into a frame.

[0044] It can be understood that with such an arrangement, the first forming mechanism 300, the second forming mechanism 400 and the forming die head 21 cooperate to complete the folding, forming and gluing of the frame paper blank, so that the folding and gluing processing can be completed in one workstation, and the folded and formed materials will not become loose during transfer, thereby ensuring the accuracy of the formed frame and improving the efficiency of the frame forming.

[0045] To assist in forming the enclosure, refer to Figures 1 to 5 In some embodiments, the first forming mechanism 300 and the second forming mechanism 400 both further include an extrusion assembly 35. The extrusion assemblies 35 of the first forming mechanism 300 and the second forming mechanism 400 are arranged opposite to each other and are located below the corresponding second driving unit 34. The extrusion assembly 35 includes an extrusion plate 351, a guide rod 352 and an extrusion driving unit 353. The guide rod 352 is movably connected to the mounting seat 31. The extrusion plate 351 is arranged at one axial end of the guide rod 352 and is transmission-connected to the extrusion driving unit 353 arranged between the two guide rods 352. During the folding and forming process of the frame, the extrusion driving units 353 of the two extrusion assemblies 35 drive the corresponding extrusion plates 351 to approach the forming die 21, so that the two extrusion plates 351 block the outward expansion of the head and tail ends of the frame paper blank.

[0046] In some optional embodiments, the extrusion drive unit 353 includes but is not limited to one of the following: a drive cylinder, a linear motor.

[0047] In this embodiment, when the forming die 21 presses the cardboard area at the middle position of the frame paper blank onto the pushing mechanism 500, and the first folding knife 33 and the second folding knife 41 press the cardboard areas on both sides of the forming die 21 onto the corresponding outer side walls of the forming die 21, the extrusion drive unit 353 pushes the connecting plate connecting the two guide rods 352 to move, so that the two guide rods 352 can slide laterally relative to the mounting seat 31, and drive the extrusion plate 351 located at the axial front end of the guide rod 352 to move, and the two extrusion plates 351 move towards each other, so that the extrusion plates 351 approach the forming die 21 and push the head and tail of the frame paper blank. The cardboard areas at both ends are squeezed against the forming die 21 or the cardboard areas at both ends of the frame paper blank are blocked from retracting, thereby pulling the two ends of the frame paper blank relatively apart, so as to avoid the looseness of the formed frame; it can be understood that before the two ends of the frame paper blank are not glued with adhesive paper, the first folding knife 33 and the second folding knife 41 fold the cardboard areas, which will cause the local area of ​​the frame paper blank to warp or move away from the forming die 21, thereby making the frame in a loose state and unable to perform the final adhesive paper gluing. By adopting the squeezing component 35, the two ends of the frame paper blank can be blocked from expanding outward, thereby ensuring the quality of the formed frame.

[0048] In order to carry out longitudinal positioning and calibration of the feeding frame paper blank, refer to Figures 1 to 5 In some embodiments, the first folding knife 33 and the second folding knife 41 are both provided with a positioning assembly 36, the positioning assembly 36 includes a movable positioning block 361 and a positioning baffle 362 which are longitudinally arranged opposite each other, the positioning baffle 362 is fixed on the longitudinal side of the first folding knife 33 and the second folding knife 41, the movable positioning block 361 is transmission-connected with a telescopic cylinder 363 fixed on the other longitudinal side of the first folding knife 33 and the second folding knife 41, wherein the movable positioning block 361 is driven by the telescopic cylinder 363 to move toward the corresponding positioning baffle 362 to position and fix the frame paper blank transferred to the first folding knife 33 and the second folding knife 41.

[0049] In this embodiment, at least one positioning component 36 is provided on the first folding knife 33 and the second folding knife 41. After a new frame paper blank is transferred and placed on the first folding knife 33 and the second folding knife 41, the longitudinal offset position of the frame paper blank can be calibrated through the positioning component 36, and when the frame paper blank is pressed down and folded by the forming die head 21, the front and rear ends of the frame paper blank will not produce longitudinal offset.

[0050] In order to carry out the lateral positioning and calibration of the feeding frame paper blank, refer to Figures 1 to 4In some embodiments, a limit assembly 37 is further provided on the lateral side of the first folding knife 33 away from the second folding knife 41. The limit assembly 37 includes a movable limit plate 371 and a limit driving cylinder 372 which is transmission-connected to the movable limit plate 371, wherein the limit driving cylinder 372 drives the movable limit plate 371 to move in the lateral direction to perform lateral position correction on the frame paper blank fed to the first forming mechanism 300 and the second forming mechanism 400.

[0051] In this embodiment, a limiting component 37 is provided on the lateral side of the first folding knife 33, and the limiting component 37 is used to limit the lateral movement position of the frame paper blank during the feeding process. That is, the limiting component 37 is used to limit the lateral position of the frame paper blank, so that an outer side wall corresponding to the bottom of the forming die head 21 can be pressed on the paper area in the middle position of the paper blank.

[0052] In order to realize the support of the frame paper blank, refer to Figures 1 to 4 In some embodiments, the lifting mechanism 500 includes a lifting cylinder 51, a guide light shaft 52 and a lifting support plate 53. The lifting support plate 53 is movably connected to the bottom plate 100 through the guide light shaft 52, and is transmission-connected to the lifting cylinder 51 installed between the two guide light shafts 52. The lifting cylinder 51 is used to drive the lifting support plate 53 to move vertically to a preset position to support the frame paper blank or frame that is pressed down and folded by the corresponding forming die head 21.

[0053] In this embodiment, when the forming die 21 is located directly above the first folding knife 33 and the second folding knife 41, at this time, the ejection cylinder 51 drives the ejection support plate 53 to move vertically upward to a preset position (this position is the lowest position of the corresponding forming die 21 pressing down the surrounding frame paper blank) under the guidance of the guide light axis 52. When the forming die 21 moves vertically downward and presses the paper blank and the cardboard area corresponding to the side wall of the bottom of the forming die 21 onto the ejection support plate 53 placed at the preset position, the surrounding frame paper blank and the forming die 21 are fixed, so that When the first forming mechanism 300 and the second forming mechanism 400 fold other cardboard areas and glue the adhesive paper, the frame paper blank will not move, and then it will be folded according to the pre-opened grooves to form a frame of a preset shape; and when the frame molding and adhesive paper gluing are completed, the ejecting cylinder 51 will drive the ejecting support plate 53 to move vertically downward to the initial position under the guidance of the guide light axis 52, so that the frame is separated from the ejecting support plate 53. At this time, the frame is placed on the corresponding molding die head 21 and will not be loose.
