[0039] As Figure 1-13 shown, this is the structural embodiment provided by the present invention.

[0040] Embodiment 1

[0041] A lid folding mechanism provided in this embodiment includes a feeding platform 3 for feeding the lid, a pressing mechanism 9 for positioning the lid, an upward folding mechanism for upwardly folding the end side plates 45 of the lid, and a side folding mechanism 8 for laterally folding the overlapping portion 46 of the side plates, which are used in cooperation with each other.

[0042] It should be noted that during use, the side plates 44 on both sides of the lid are bent and then placed on the feeding platform 3. The pressing mechanism 9 is used to press the lid placed on the feeding platform 3. Then, the upward folding mechanism is used to upwardly fold the end side plates 45, and the side folding mechanism 8 is used to laterally fold the overlapping portion 46 of the side plates inward. Alternatively, the side folding mechanism 8 can be used to laterally fold the overlapping portion 46 of the side plates inward first, and then the upward folding mechanism is used to upwardly fold the end side plates 45. Through the coordinated actions of the pressing mechanism, the upward folding mechanism, and the side folding mechanism, the folding and positioning of the end side plates and the overlapping portion of the side plates can be automatically completed, reducing manual intervention, lowering the labor intensity, improving the work efficiency, and at the same time, improving the binding accuracy and quality.

[0043] Specifically, this embodiment provides a specific structure of the feeding platform 3, which includes a left feeding platform unit and a right feeding platform unit used in cooperation with each other. The left feeding platform unit and the right feeding platform unit each include one L-shaped alignment clamping plate 39, and the lid is placed between the two, clamping both sides of the lid respectively.

[0044] Preferably, the left feeding platform unit and the right feeding platform unit are symmetrically arranged in structure. The right feeding platform unit includes a fixing 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. A limiting plate 41 is fixedly arranged on the upper end surface of the fixing plate 36. An L-shaped moving plate 40 is arranged on one side of the limiting plate 41. The alignment clamping plate 39 is connected to the L-shaped moving plate 40. The fixing plate 36 is provided with a through hole. The telescopic cylinder 38 is installed on one side of the fixing plate 36, and its piston rod is connected to the linkage plate 42 through the first connecting frame 37. A linkage block 43 is arranged at 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, driving the L-shaped moving plate 40 and the alignment clamping plate 39 to move through the telescopic movement of the piston rod.

[0045] It should be noted that the left feeding platform unit refers to the description of the structure of the right feeding platform unit. In the above structure, a structure for aligning the position of the lid is included.

[0046] When in use, place the box cover on the two alignment clamping plates 39 of the upper left feeding platform unit and the upper right feeding platform unit. Then, start 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 clamping plate 39 to move inward, so as to align the position of the box cover.

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

[0048] Among them, the downward pressing mechanism longitudinal driving component includes a pressing support 29 installed on the feeding platform 3 and a downward pressing cylinder 30. The downward pressing cylinder 30 is longitudinally installed on the pressing support 29, and its piston rod is connected to the lower pressing plate 31.

[0049] It should be noted that during use, the lower pressing plates 31 are driven by the downward pressing cylinders 30 on both sides to press the box cover downward, so as to ensure that the position of the box cover does not change during the subsequent folding and nailing operations.

[0050] Specifically, this embodiment provides a structure of the upward turning mechanism 11, which includes an upward turning mechanism rotation driving component and an upward turning plate 27. The upward turning mechanism rotation driving component drives the upward turning plate 27 to turn within a preset angle range.

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

[0052] Among them, the upward turning mechanism rotation driving component includes a rotating rod 26 and an upward turning plate driving motor 28. The upward turning plate 27 is installed on the rotating rod 26, and the upward turning plate driving motor 28 drives the rotating rod 26 to rotate, thereby driving the upward turning plate 27 to turn.

[0053] Specifically, this embodiment provides a side turning mechanism 8, which includes a left side turning mechanism unit and a right side turning mechanism unit used in cooperation. Both the left side turning mechanism unit and the right side turning mechanism unit include a second bracket 35 that can move left and right and back and forth and is used to side turn the overlapping part 46 of the side plates.

[0054] Among them, the left-side turning mechanism unit and the right-side turning mechanism unit are symmetrically arranged in structure, and both further include a first driving cylinder 32, a first bracket 33, and a second driving cylinder 34. The first driving cylinder 32 is installed on the loading platform 3 in the front-back direction, and its piston rod is connected to a first bracket 33. A second driving cylinder 34 installed in the left-right direction is arranged on the first bracket 33, and the piston rod of the second driving cylinder 34 is connected to a 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. The structure of an L-shaped block plus a flap as shown in the figure can also be selected.

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

[0057] It should be noted that in this application, the cylinders and motors in the above structure are controlled by a controller to act in sequence, enabling the automatic operation of the folding of the box cover.

[0058] Embodiment 2

[0059] This embodiment provides a box cover binding machine, which includes a head mechanism 7 for nailing the box cover, the box cover folding mechanism described above, and a moving support mechanism for driving the box cover folding mechanism to move.

[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 Figure 2 shown. Among them, the head support 13 is installed on the base 1, the head transverse movement guide rail 15 is arranged on the head support 13, and the two heads 13 are respectively arranged on the head transverse movement guide rail 15, and their positions can be adjusted. And a locking member in the prior art can be provided to fix their positions. The head structure is provided with two heads, which can simultaneously nail the two sides at one end of the box cover. The head 14 adopts the head in the prior art and will not be elaborated here.

[0061] Most box covers need to be nailed multiple times on one side. Therefore, in order to automate the nailing of multiple nails, a moving support mechanism that can move automatically under the control of a controller is provided.

[0062] Specifically, the mobile support mechanism can adopt an existing structure or be set as the following structure: It includes a base 1, a lifting drive motor 2, a lifting frame 4, a longitudinal guide rail 5, a front-back moving frame 6, and a platform support 12. Among them, the lifting frame 4 is arranged above the base 1, the longitudinal guide rail 5 and the lifting drive motor 2 are both arranged 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 a nut block used in cooperation with the longitudinal lead screw is installed on the lifting frame 4, thereby driving the lifting frame to lift and lower; both sides of the lifting frame 4 are provided with front-back guide rails 23, the lower end of the front-back moving frame 6 is slidably connected to the front-back guide rails 23, the lifting frame 4 is provided with a front-back drive motor 20, the front-back drive motor 20 drives the front-back lead screw 21 to rotate, and a nut block used in cooperation with the front-back lead screw 21 is installed on the front-back moving frame 6, thereby driving the front-back moving frame 6 to move back and forth; the upper end of the front-back moving frame 6 is slidably connected to the platform support 12, the front-back moving frame 6 is provided with a transverse drive motor 22, the front-back moving frame 6 drives the moving frame lead screw 24 to rotate, and a nut block used in cooperation 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; the platform support 12 is provided with a platform guide rail 25. The lower ends of the fixing plates 36 of the left feeding platform unit and the right feeding platform unit are both provided with sliders used in cooperation with the slide rails of the platform guide rail 25, so as to adjust the positions of the left feeding platform unit and the right feeding platform unit, and after adjustment, locking is carried out.

[0063] It should be noted that the present application controls the cylinders and motors in the above structure to act in sequence through a controller, and can realize the automatic operation of case cover binding.

[0064] In addition, it further includes a preliminary positioning mechanism 10, which quickly positions the front and back positions of the case cover during feeding. The preliminary positioning mechanism 10 includes a cylinder base plate 16, a feeding positioning plate 17, a positioning plate cylinder 18, and a cylinder moving seat 19. Among them, the piston rod of the positioning plate cylinder 18 is installed with the feeding positioning plate 17, which can drive the feeding positioning plate 17 to stretch and retract a preset length. The positioning plate cylinder 18 is installed on the cylinder base plate 16, the cylinder base plate 16 is connected to the cylinder moving seat 19 through a slide rail and slider mechanism, and the cylinder moving seat 19 is slidably connected to the head transverse moving guide rail 15, thereby being able to adjust the position of the feeding positioning plate 17.

[0065] The operation process is as follows:

[0066] When in use, bend the side plates 44 on both sides of the box cover and place them on the loading platform 3. First, extend the feeding positioning plate 17, and use the initial positioning mechanism to limit the feeding of the box cover in the front-back direction. Then, start 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 clamping plate 39 to move inward, so as to align the position of the box cover left and right. Then, use the pressing mechanism 9 to press the box cover placed on the loading platform 3. After that, the feeding positioning plate 17 retracts. Then, use the upward turning mechanism to turn up the end side plate 45, and then use the side turning mechanism 8 to turn the overlapping part 46 of the side plates inward. Then, use the moving support mechanism to drive the box cover to rise to the nailing position for nailing. The side turning mechanism resets. Continuously change the position and perform nailing multiple times until nailing is completed at this end. Then, the above-mentioned mechanisms reset. Remove the box cover, repeat the above operations, and perform nailing at the other end.

[0067] It should be noted that Figure 14 As a structural schematic diagram of the box cover, the end side plate 45 can be turned up first, and then the overlapping part 46 of the side plates can be turned sideways so that the overlapping part 46 of the side plates is outside the end side plate 45. Or, according to actual needs, the overlapping part 46 of the side plates can be turned sideways first, and then the end side plate 45 can be turned up. Just make routine adjustments to the device.
