[0002] In the process of preparing the frame of the packaging box, a paper blank with notches is folded to form a frame of a preset shape, such as a square or diamond. After folding, the frame joints (the connection between the head and tail ends of the paper blank) are glued with adhesive tape to prevent the folded frame from becoming loose during the transfer to the next station, which will affect subsequent processing and the molding quality of the frame.

[0003] In the related art, when adhesive tape is used to glue the joints of the frame, if adhesive tape with a smaller width is used, gaps will exist in the radial direction (the width direction of the paper blank) of the joints of the frame, resulting in loose bonding of the frame and easy tearing of the frame along the gaps; while if adhesive tape with a larger width is used, the adhesive tape will extend along the side edges, which will easily cause burrs on the sides of the frame, affecting the appearance of the frame. At the same time, if adhesive tape with a smaller width or a larger width is used to glue the joints of the frame, only the outer side of the frame will be glued.

The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0031] Figure 1 The three-dimensional structure diagram of the side edge sealing stripping device of the embodiment of the present application. The side edge sealing stripping device of the frame shown in the figure is applied to the molding process of the frame of the packaging box, and two folding fingers 41 are used to turn the two side folds in the longitudinal direction of the frame inwardly into the frame and bond them to the inner wall of the frame, so that the folded side folds are bonded to the joint inside the frame to prevent the head or tail end of the paper blank from being separated from the adhesive tape, and ensure that the joint of the frame is firmly connected; the two clamping components 51 of the stripping mechanism 500 synchronously clamp the frame movement to complete the side folding edge sealing, and ensure that the frame is not deformed and the stripping is completed.

[0032] See also Figures 1 to 5The frame side edge stripping device of the embodiment of the present application includes a base 100, a feeding mechanism 200 and a gantry 300 are provided on the base 100, a folding mechanism 400 is provided on the truss arm 31 of the gantry 300, and the folding mechanism 400 is also located directly above the feeding fixture 21 of the feeding mechanism 200 in terms of the setting position, and the gantry 300 is also provided with a stripping mechanism 500 that is movably connected to the feeding fixture 21, wherein,

[0033] The feeding mechanism 200 is used to drive the feeding fixture 21 to transfer the folded and formed surrounding frame to the docking position with the folding mechanism 400, wherein the joint of the folded and formed surrounding frame is provided with a side folding edge extending along the width direction of the surrounding frame.

[0034] In this embodiment, the loading fixture 21 can receive the frame from the previous workstation (the workstation for folding and forming the frame), and then carry the frame to the docking position with the folding mechanism 400; at the same time, the docking position between the loading fixture 21 and the folding mechanism 400 is also the docking position between the loading fixture 21 and the stripping mechanism 500, that is, after the loading fixture 21 is transferred to the corresponding position, it will perform side edge sealing and stripping in sequence, and then the loading fixture 21 is driven to move to the previous workstation to receive the corresponding frame.

[0035] In this embodiment, the loading clamp 21 also serves as a fixture for supporting and fixing the frame, so that the folding mechanism 400 will not cause deformation of the frame during the side folding and edge sealing process of the frame, and the stripping mechanism 500 will not cause deformation of the frame due to excessive clamping force before the frame is stripped from the loading clamp 21.

[0036] The folding mechanism 400 is used to drive the two folding fingers 41 to move toward each other along the longitudinal direction after moving the two folding fingers 41 to the corresponding positions on the front and rear sides of the loading clamp 21 in the longitudinal direction, so as to turn the side folding edges inward to bond with the inner wall of the frame.

[0037] In this embodiment, after the side folding edge sealing is completed, the two folding fingers 41 are driven to move relatively away from each other so that the folding knife 411 of the folding finger 41 changes from the inserted loading fixture 21 state to the exited loading fixture state 21, and then the two folding fingers 41 are driven to move vertically upward to facilitate the stripping mechanism 500 to strip the frame.

[0038] The stripping mechanism 500 is used to drive two clamping assemblies 51 arranged opposite to each other to move toward the frame with the folded edge completed and clamp the frame, and then drive the two clamping assemblies 51 to clamp the frame and move it along the longitudinal direction, and strip the frame from the loading fixture 21.

[0039] In the above-mentioned enclosure side edge stripping device, a feeding mechanism 200 is used to feed the enclosure with side folded edges to the docking point with the folding mechanism 400, and the enclosure is supported by the feeding fixture 21 of the feeding mechanism 200 so that the enclosure does not deform during the transfer process. After the two folding fingers 41 of the folding mechanism 400 are moved to the front and rear sides of the longitudinal direction of the enclosure, the two folding fingers 41 move toward each other along the longitudinal direction, and the two side folded edges in the longitudinal direction of the enclosure are correspondingly turned inward into the enclosure and aligned with the inner wall of the enclosure. Bonding, by gluing the inwardly folded side folded edges to the joints on the inner side of the frame, prevent the head or tail end of the paper blank from being separated from the adhesive tape, and ensure that the joints of the frame are firmly connected; the two clamping components 51 of the stripping mechanism 500 synchronously clamp the movement of the frame with the side folded edges sealed, and ensure that the frame is not deformed and the stripping is completed, which solves the problem of loose bonding and easy looseness at the joints of the frames formed by the frame forming equipment in the related art, and achieves the beneficial effect of improving the quality of the formed frames and reducing the defective rate of the frames.

[0040] In order to drive the loading fixture 21 to move to at least the docking position with the folding mechanism 400, refer to Figures 1 to 5 In some embodiments, the feeding mechanism 200 further comprises a support seat 22 disposed on the base 100, a first guide member 23 extending vertically is disposed on the side wall of the support seat 22, the first guide member 23 is movably connected to a slide seat 24, a feeding fixture 21 is disposed on one end of the slide seat 24 away from the movably connected end of the slide seat 24, and a first driving unit 25 drivingly connected to the slide seat 24 is further disposed on the side wall of the support seat 22, wherein,

[0041] The first driving unit 25 is used to drive the slide 24 to move along the first guide member 23 to drive the loading fixture 21 to transfer the folded frame to the docking position with the folding mechanism 400.

[0042] In some of the optional embodiments, the first drive unit 25 that can drive the slide 24 to move along the first guide member 23 is suitable for the first drive unit 25 of the embodiment of the present application. For example, the first drive unit 25 includes but is not limited to one of the following: an electric cylinder slide, a linear motor slide, and a linear screw slide; in this embodiment, the first guide member 23 includes a linear guide rail.

[0043] To achieve the side fold edge sealing, refer to Figures 1 to 5In some embodiments, the folding mechanism 400 further includes a second driving unit 42, a bearing sleeve 43, an optical axis 44 and a mounting seat 45. The truss arm 31 is provided with two longitudinally spaced bearing sleeves 43, each bearing sleeve 43 is provided with a vertically extending optical axis 44, and one end of the optical axis 44 away from the bearing sleeve 43 is connected to the mounting seat 45.

The mounting seat 45 is also connected to the second driving unit 42 which is arranged between the two optical axes 44 and fixed to the bottom end surface of the truss arm 31.

[0044] The second driving unit 42 is used to drive the mounting seat 45 to drive the two optical axes 44 to telescopically move along the corresponding bearing sleeves 43, so as to drive the two folding fingers 41 to move vertically to the longitudinal sides of the loading fixture 21 at the set position through the mounting seat 45.

[0045] In this embodiment, the second drive unit 42 that drives the mounting base 45 to move vertically with the optical axis 44 as the guide axis meets the requirements of the second drive unit 42 of the embodiment of the present application. For example, the second drive unit 42 includes but is not limited to one of the following: a drive cylinder, a linear motor; in some optional embodiments, the drive cylinder is a long-axis cylinder.

[0046] The two folding fingers 41 are used to drive the corresponding folding knives 411 to move toward each other in the longitudinal direction, so that after aligning with the corresponding side folding edges, the two side folding edges of the frame are folded into the inner circle of the frame and folded and pressed until they are bonded to the inner wall of the frame.

[0047] It can be understood that, with such an arrangement, after the two folding fingers 41 of the folding mechanism 400 are moved to the front and rear sides in the longitudinal direction of the frame, the two folding fingers 41 are moved toward each other in the longitudinal direction, and the two side folds in the longitudinal direction of the frame are correspondingly turned inward into the frame and bonded to the inner wall of the frame. The inwardly folded side folds are glued to the joint on the inner side of the frame to prevent the head end or the tail end of the paper blank from detaching from the adhesive tape, thereby ensuring that the joint of the frame is firmly connected.

[0048] In some optional embodiments, the folding finger 41 further includes a first cylinder 412 fixedly connected to the mounting seat 45 , and the folding knife 411 is connected to the piston of the first cylinder 412 .

The two transmission assemblies 53 are connected in transmission through the synchronization assembly 54. The synchronization assembly 54 is also connected in transmission with the third driving unit 55 arranged on the side plate of the hanging seat 52. The bottom end surface of the bottom plate of the hanging seat 52 is fixedly provided with The second guide member 57 extending in the longitudinal direction and the second guide members 57 located on both sides of the suspension seat 52 are respectively movably connected to a sliding plate 56, each sliding plate 56 is transmission-connected to a transmission assembly 53, and a third guide member 59 extending in the transverse direction is provided at the bottom of the sliding plate 56, and the third guide member 59 is connected to the vertical plate 510 arranged vertically, and the vertical plate 510 is also connected to the suspension seat 52 through a telescopic adjustment assembly 58, and the telescopic adjustment assembly 58 can drive the vertical plate 510 to move along the third guide member 59, and the clamping assembly 51 is arranged vertically to the vertical plate 510, and the two clamping assemblies 51 are arranged horizontally opposite to each other, wherein,

[0050] The third driving unit 55 drives the two transmission components 53 through the synchronization component 54 to respectively drive the corresponding sliding plates 56 to move along the corresponding second guide members 57 in the longitudinal direction, so that the clamping component 51 located on the vertical plate 510 moves with the vertical plate 510 and the sliding plate 56;

[0051] After the two clamping assemblies 51 move with the vertical plate 510 and the sliding plate 56 to align with the surrounding frame, they move toward the surrounding frame and clamp the surrounding frame, and in the process of clamping the surrounding frame and moving along the vertical plate 510 and the sliding plate 56 in the longitudinal direction, the surrounding frame is removed from the loading fixture 21.

[0052] It can be understood that, with such an arrangement, the two clamping components 51 of the stripping mechanism 500 synchronously clamp the movement of the frame for side folding and edge sealing, ensuring that the stripping is completed without deformation of the frame.

[0053] It should be understood that the third drive unit 55 of the embodiment of the present application is connected to the synchronization component 54 through the synchronization wheel and the transmission belt, and then connected to the two transmission components 53 through the synchronization component 54. The corresponding transmission relationship is clear and understandable. For those skilled in the art, it is clear that the third drive unit 55 provides power, drives the two transmission components 53 through the synchronization component 54, and drives the corresponding sliding plates 56 to slide.

[0055] It can be understood that, with such a configuration, the two second extrusion assemblies 528 of the stripping assembly 52 are clamped by the surrounding frame and cooperate to drive the two second extrusion assemblies 528 to move longitudinally, thereby achieving fast and effective stripping and improving processing efficiency.
