[0040] Example 1

[0041] This embodiment provides a box lid folding mechanism, which includes a feeding platform 3 for feeding the box lid, a pressing mechanism 9 for positioning the box lid, an upward folding mechanism for folding the end side plate 45 of the box lid upward, and a side folding mechanism 8 for folding the overlapping part 46 of the side plate to the side.

[0042] It should be noted that during use, the side panels 44 on both sides of the box lid are bent and placed into the loading platform 3. The pressing mechanism 9 is used to press the box lid on the loading platform 3. Then, the flipping mechanism is used to flip the end side panel 45 upwards, and the side flipping mechanism 8 is used to fold the overlapping part 46 of the side panel inwards. Alternatively, the side flipping mechanism 8 can be used to fold the overlapping part 46 of the side panel inwards first, and then the flipping mechanism can be used to flip the end side panel 45 upwards. Through the coordinated action of the pressing mechanism, the flipping mechanism, and the side flipping mechanism, the folding and positioning of the overlapping part of the end side panel and the side panel can be completed automatically, reducing manual intervention, reducing labor intensity, improving work efficiency, and improving the accuracy and quality of binding.

[0043] Specifically, this embodiment provides a specific structure of a loading platform 3, which includes a left loading platform unit and a right loading platform unit used in conjunction with each other. The left loading platform unit and the right loading platform unit each include an L-shaped alignment clamp 39, with the box cover placed between the two, clamping the two sides of the box cover respectively.

[0044] Preferably, the left and right loading platform units are symmetrically arranged. The right loading platform unit includes a fixed plate 36, a first connecting frame 37, a telescopic cylinder 38, an alignment clamping plate 39, an L-shaped moving plate 40, a limiting plate 41, a linkage plate 42, and a linkage block 43. The upper end face of the fixed plate 36 is fixedly provided with the limiting plate 41. An L-shaped moving plate 40 is provided on one side of the limiting plate 41. The alignment clamping plate 39 is connected to the L-shaped moving plate 40. The fixed plate 36 is provided with a through hole. The telescopic cylinder 38 is installed on one side of the fixed plate 36. Its piston rod is connected to the linkage plate 42 through the first connecting frame 37. A linkage block 43 is provided on the upper end of the linkage plate 42. The linkage block 43 passes through the through hole and is connected to the L-shaped moving plate 40. The extension and retraction of the piston rod drives the L-shaped moving plate 40 and the alignment clamping plate 39 to move.

[0045] It should be noted that the description of the left upper loading platform unit refers to the structure of the right upper loading platform unit. The above structure includes the alignment of the box cover.

[0046] When in use, place the box cover on the two alignment clamps 39 of the left and right loading platform units. Then, activate the telescopic cylinders 38 on both sides. The telescopic cylinders 38 drive the first connecting frame 37, the linkage plate 42, the linkage block 43, the L-shaped moving plate 40, and the alignment clamps 39 to move inward, thereby aligning the position of the box cover.

[0047] Specifically, this embodiment also provides a specific structure of the pressing mechanism 9, which includes a left pressing mechanism unit and a right pressing mechanism unit used in cooperation. The left pressing mechanism unit and the right pressing mechanism unit both include a pressing mechanism longitudinal driving component and a pressing plate 31. The pressing mechanism longitudinal driving component drives the pressing plate 31 to rise and fall.

[0048] The longitudinal driving component of the pressing mechanism includes a pressing bracket 29 and a pressing cylinder 30 installed on the loading platform 3; the pressing cylinder 30 is longitudinally installed on the pressing bracket 29, and its piston rod is connected to the pressing plate 31.

[0049] It should be noted that during use, the downward pressing cylinders 30 on both sides drive the downward pressing plate 31 to press the box cover down, thereby ensuring that the position of the box cover does not change during subsequent folding and nailing work.

[0050] Specifically, this embodiment provides a structure for an upward flipping mechanism 11, which includes an upward flipping mechanism rotation drive component and an upward flipping plate 27. The upward flipping mechanism rotation drive component drives the upward flipping plate 27 to flip within a preset angle range.

[0051] It should be noted that the upward flipping mechanism is used to flip the basically horizontal end plate 45 upwards along the crease by about 90 degrees, so that it is in a basically vertical or vertical state.

[0052] The rotating drive component of the flipping mechanism includes a rotating rod 26 and an upper flipping plate drive motor 28. The upper flipping plate 27 is mounted on the rotating rod 26. The upper flipping plate drive motor 28 drives the rotating rod 26 to rotate, thereby causing the upper flipping plate 27 to flip.

[0053] Specifically, this embodiment provides a side-flipping mechanism 8, which includes a left side-flipping mechanism unit and a right side-flipping mechanism unit used in conjunction with each other. Both the left side-flipping mechanism unit and the right side-flipping mechanism unit include a second bracket 35 that can move in the left and right directions and in the front and back directions for flipping the overlapping part 46 of the side plate.

[0054] The left and right flipping mechanism units are symmetrically arranged and each includes a first driving cylinder 32, a first bracket 33, and a second driving cylinder 34. The first driving cylinder 32 is mounted on the loading platform 3 in a front-to-back direction, and its piston rod is connected to the first bracket 33. The first bracket 33 is equipped with a second driving cylinder 34 mounted in a left-to-right direction, and the piston rod of the second driving cylinder 34 is connected to the second bracket 35.

[0055] It should be noted that the shape of the second bracket is not limited, as long as it can meet the folding of the overlapping part of the side plates. Alternatively, an L-shaped block plus a flap structure as shown in the figure can be selected.

[0056] It should be noted that during use, the second drive cylinder 34 drives the second bracket 35 to extend, folding the overlapping part 46 of the side plate inward along the crease. Then, the first drive cylinder 32 pulls the second drive cylinder 34 and the second bracket back through the first bracket 33, thereby folding the overlapping part 46 of the side plate into place, so as to fit as close as possible to the folded end plate 45.

[0057] It should be noted that this application uses a controller to control the cylinders and motors in the above structure to operate in sequence, thereby enabling the automatic operation of the lid folding.

[0058] Example 2

[0059] This embodiment provides a box lid binding machine, including a head mechanism 7 for nailing the box lid, the box lid folding mechanism, and a moving support mechanism for moving the box lid folding mechanism.

[0060] It should be noted that the head mechanism 7 includes a head support 13, two heads 14, and a head transverse movement guide rail 15, as shown below. Figure 2 As shown. The machine head bracket 13 is mounted on the base 1, and the machine head transverse movement guide rail 15 is mounted on the machine head bracket 13. Two machine heads 13 are respectively mounted on the machine head transverse movement guide rail 15, and their positions are adjustable. This structure can be secured to their positions using existing locking mechanisms. The machine head structure has two machine heads, enabling simultaneous nailing work on both sides of one end of the casing cover. The machine head 14 uses existing machine heads and will not be described in detail further.

[0061] Most box lids require multiple nails on one side. Therefore, to automate the nailing process, a mobile support mechanism that can move independently under the control of a controller is installed.

[0062] Specifically, the mobile support mechanism can adopt an existing structure or be configured as follows: including a base 1, a lifting drive motor 2, a lifting frame 4, a longitudinal guide rail 5, a forward and backward moving frame 6, and a platform support 12; wherein, the lifting frame 4 is disposed above the base 1, the longitudinal guide rail 5 and the lifting drive motor 2 are both disposed on the base 1, the lifting frame 4 is slidably connected to the longitudinal guide rail 5, the lifting drive motor 2 drives the longitudinal lead screw to rotate, and the nut block used in conjunction with the longitudinal lead screw is installed on the lifting frame 4, thereby driving the lifting frame to rise and fall; forward and backward guide rails 23 are provided on both sides of the lifting frame 4, and the lower end of the forward and backward moving frame 6 is slidably connected to the forward and backward guide rails 23. A forward and backward drive motor 20 is installed on the 4th platform, which drives a forward and backward lead screw 21 to rotate. A nut block that cooperates with the forward and backward lead screw 21 is installed on the forward and backward moving frame 6, thereby driving the forward and backward moving frame 6 to move forward and backward. A platform support 12 is slidably connected to the upper end of the forward and backward moving frame 6. A horizontal drive motor 22 is installed on the forward and backward moving frame 6, which drives a moving frame lead screw 24 to rotate. A nut block that cooperates with the moving frame lead screw 24 is installed on the platform support 12, thereby driving the platform support 12 to move left and right. A platform guide rail 25 is installed on the platform support 12. The lower end of the fixing plate 36 of the left loading platform unit and the right loading platform unit is provided with a slider that cooperates with the slide rail of the platform guide rail 25, thereby adjusting the position of the left loading platform unit and the right loading platform unit. After adjustment, the position is locked.

[0063] It should be noted that this application uses a controller to control the cylinders and motors in the above structure to operate in sequence, thereby enabling the automatic operation of the box lid binding.

[0064] Additionally, a preliminary positioning mechanism 10 is included, which quickly positions the front and rear positions of the box lid feed. The preliminary positioning mechanism 10 includes a cylinder base plate 16, a feed positioning plate 17, a positioning plate cylinder 18, and a cylinder moving seat 19. The piston rod of the positioning plate cylinder 18 is mounted on the feed positioning plate 17, which can drive the feed positioning plate 17 to extend or retract by a preset length. The positioning plate cylinder 18 is mounted on the cylinder base plate 16, and the cylinder base plate 16 is connected to the cylinder moving seat 19 through a slide rail slider mechanism. The cylinder moving seat 19 is slidably connected to the machine head transverse moving guide rail 15, thereby adjusting the position of the feed positioning plate 17.

[0065] The process is as follows:

[0066] In use, the side plates 44 on both sides of the box cover are bent and placed into the loading platform 3. The feeding positioning plate 17 extends first, and the initial positioning mechanism limits the feeding of the box cover in the front and back directions. Then, the telescopic cylinders 38 on both sides are activated. The telescopic cylinders 38 drive the first connecting frame 37, the linkage plate 42, the linkage block 43, the L-shaped moving plate 40, and the alignment clamping plate 39 to move inward, thereby aligning the box cover left and right. Then, the pressing mechanism 9 is used to press the box cover placed on the loading platform 3 tightly. After that, the feeding positioning plate 17 is retracted. Then, the flipping mechanism is used to flip the end side plate 45 upward, and the side flipping mechanism 8 is used to fold the overlapping part 46 of the side plate inward. Then, the moving support mechanism is used to lift the box cover to the nailing position for nailing. The side flipping mechanism is reset. The position is changed continuously, and nailing is performed multiple times until the nailing of this end is completed. The above mechanisms are reset. The box cover is removed, and the above operation is repeated to nail the other end.

[0067] It should be noted that, Figure 14 The diagram shows the structure of the lid. The end side plate 45 can be flipped up first, and then the overlapping part 46 of the side side plate can be flipped to the side so that the overlapping part 46 of the side side plate is outside the end side plate 45. Alternatively, the overlapping part 46 of the side side plate can be flipped to the side first, and then the end side plate 45 can be flipped up. The device can be adjusted as usual.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
