DETAILED DESCRIPTION
[0018] The present application will now be described in further detail with reference to the drawings. The drawings are simplified schematic illustrations of the basic structure of the present application and therefore only show what is relevant to the present application.
[0019] As shown in the drawings, a packaging box end compression system comprises an abutting mechanism, which comprises: Figures 1-13 a first pressing rod 20, the lower end of the first pressing rod 20 being provided with a first pressing plate 23; a conversion frame 5, which is arranged to slide in the vertical direction, the two ends of the conversion frame 5 being provided with wedge-shaped guide blocks 50; the lower end of the first pressing rod 20 is arranged to slide through the conversion frame 5, and the first pressing rod 20 and the conversion frame 5 are arranged to elastically slide relative to each other; a side limiting rod 53, which is arranged to elastically slide in the horizontal plane perpendicular to the transport direction of the carton 7, one end of the side limiting rod 53 abutting against the wedge-shaped surface 51 of the wedge-shaped guide block 50, and the other end of the side limiting rod 53 being provided with a correcting plate 55. The abutting mechanism is the core functional component of the system, and the first pressing rod 20 serves as a vertical pressure applying base member, and the first pressing plate 23 at the lower end of the first pressing rod 20 can be made of rubber material to avoid direct hard contact and damage to the carton 7.
[0020] The conversion frame 5 is arranged to slide in the vertical direction, the two wedge-shaped guide blocks 50 are symmetrically distributed, and the wedge-shaped surface 51 is inclined towards one side of the side limiting rod 53; the lower end of the first pressing rod 20 is arranged to slide through the conversion frame 5, and the two are connected by an elastic structure, so that the conversion frame 5 can slide vertically relative to the first pressing rod 20.
[0021] The side limiting rod 53 is arranged to elastically slide in the horizontal plane perpendicular to the transport direction of the carton 7, one end of the side limiting rod 53 abutting against the wedge-shaped surface 51 of the wedge-shaped guide block 50, and the other end of the side limiting rod 53 being provided with a correcting plate 55.
[0022] When the posture of the carton 7 is skewed, during the downward sliding of the conversion frame 5, the wedge-shaped surface 51 of the wedge-shaped guide block 50 will press the side limiting rod 53, pushing the correcting plate 55 to abut against the side wall of the carton 7 transversely, so as to first correct the posture; then the first pressing plate 23 further presses the top of the carton 7, realizing the sequential action of "first correction and then pressing". Thus, the problem of inconvenient compression caused by irregular posture in the background art is solved, and the correction and pressing are realized by mechanical linkage to improve the compression precision.
[0023] In some further embodiments, a limiting handle 21 is arranged on a section of the first pressing rod 20 above the conversion frame 5, and a first spring 22 is arranged between the limiting handle 21 and the conversion frame 5.
[0024]
[0025] A limiting handle 21 is arranged on the first pressing rod 20 above the conversion frame 5. The limiting handle 21 can be fixed by screwing a nut or formed integrally. The outer diameter of the limiting handle 21 is larger than the diameter of the through hole of the conversion frame 5 through which the first pressing rod 20 passes, so as to prevent the conversion frame 5 from sliding off the lower end of the first pressing rod 20.
[0026] The first spring 22 between the limiting handle 21 and the conversion frame 5 is sleeved on the first pressing rod 20 and is in a compressed state in the initial state.
[0027] When the conversion frame 5 descends with the first pressing rod 20, the wedge-shaped guide block 50 first pushes the side limiting rod 53 to correct the carton 7. At this time, the first pressing plate 23 has not yet contacted the carton 7. When continuing to descend, the first pressing plate 23 abuts against the top of the carton 7, the conversion frame 5 stops vertical movement under the reaction force of the carton 7, the first pressing rod 20 continues to descend relative to the conversion frame 5, and the first spring 22 is compressed and stores elastic potential energy. The arrangement of the first spring 22 not only provides elastic buffering for the conversion frame 5 to avoid rigid impact in the correction and pressing process, but also ensures the continuous force of the wedge-shaped guide block 50 on the side limiting rod 53 through elastic deformation, so as to ensure the stability of the correction effect and realize the separation of the action time sequence of "correction - pressing".
[0028] In some further embodiments, a first guide rod 57 is arranged on the conversion frame 5, the top of the first guide rod 57 is slidingly arranged on the rack 4, and the top of the first pressing rod 20 is connected with the telescopic end of the first cylinder 2.
[0029] The first guide rod 57 on the conversion frame 5 can be symmetrically arranged in two, and the top is slidingly arranged in the vertical sliding sleeve of the rack 4 to provide accurate guidance for the upward and downward sliding of the first pressing rod 20 and prevent the first pressing rod 20 from being laterally deviated during the sliding process.
[0030] The top of the first pressing rod 20 is connected with the telescopic end of the first cylinder 2 through a flange or a pin shaft, and the first cylinder 2 is fixed on the top of the rack 4 to provide an automatic power source for the vertical movement of the first pressing rod 20.
[0031] In some further embodiments, a guide rail 56 is arranged on the rack 4, and the wedge-shaped guide block 50 is slidingly arranged on the guide rail 56.
[0032] The guide rail 56 on the rack 4 is arranged in the upward and downward direction and is slidingly matched with the side wall of the wedge-shaped guide block 50, which can adopt a structure of embedding a convex rail into a groove. The guide rail 56 forms sliding limiting for the wedge-shaped guide block 50, so as to ensure that the wedge-shaped guide block 50 always moves along the preset track when the conversion frame 5 slides upward and downward, and avoid the wedge-shaped surface 51 and the side limiting rod 53 from being out of contact due to vibration or uneven force. The guide structure ensures the stability of the lateral movement of the side limiting rod 53, prevents the correction plate 55 from being "stuck" or "deviated", and further improves the reliability of the posture correction of the carton 7.
[0033] In some further embodiments, the rack 4 is provided with a sliding frame 560, the wedge-shaped guide block 50 is located in the area surrounded by the sliding frame 560, the side limiting rod 53 is slidingly arranged on the sliding frame 560, and the sliding frame 560 is provided with an abutting ball head 52 at one end facing the wedge-shaped guide block 50; the second spring 54 is arranged between the abutting ball head 52 and the sliding frame 560, and the second spring 54 is sleeved on the side limiting rod 53.
[0034] The sliding frame 560 on the rack 4 is in a rectangular frame structure, and the wedge-shaped guide block 50 is located in the surrounding area thereof to form a safe limiting for the wedge-shaped guide block 50.
[0035] The side limiting rod 53 is slidingly arranged in the side wall through hole of the sliding frame 560, and a linear bearing can be arranged in the through hole to reduce sliding friction.
[0036] The abutting ball head 52 provided at one end of the sliding frame 560 facing the wedge-shaped guide block 50 can also adopt a ball or spherical convex structure in other embodiments, which is in rolling contact with the wedge-shaped surface 51 to convert sliding friction into rolling friction and reduce component wear.
[0037] The second spring 54 between the abutting ball head 52 and the sliding frame 560 is sleeved on the side limiting rod 53, which initially pushes the side limiting rod 53 to always adhere to the wedge-shaped surface 51; when the conversion frame 5 rises, the extrusion force of the wedge-shaped surface 51 disappears, the second spring 54 pulls the side limiting rod 53 to reset, and the correction plate 55 is separated from the carton 7 to reserve space for the conveying of the next carton 7. Thus, the automatic resetting of the side limiting rod 53 is realized without the need for additional driving parts, which simplifies the structure, reduces energy consumption, and prolongs the service life of the components due to the rolling contact design.
[0038] In some further embodiments, the abutting mechanism further comprises a second pressing rod 30, and the second pressing rod 30 is arranged obliquely, and the bottom of the second pressing rod 30 is provided with a second pressing plate 35, and the second pressing plate 35 is arranged vertically.
[0039] The top of the second pressing rod 30 is connected to the extension end of the second air cylinder 3.
[0040] The second pressing rod 30 of the abutting mechanism is arranged obliquely, and the inclination angle thereof can be adjusted according to the position of the sealing folded page of the carton 7 (usually 30°-60° with the vertical direction), and the bottom of the second pressing rod 30 is provided with a second pressing plate 35, and the second pressing plate 35 is in the form of a vertical plate and is adapted to the vertical surface of the sealing folded page of the carton 7.
[0041] The first pressing plate 23 mainly realizes the pressing limiting of the top of the carton 7, and the combination of the second pressing rod 30 and the second pressing plate 35 is targeted to act on the sealing folded page, and the oblique pressing rod can avoid the top structure of the carton 7, so that the second pressing plate 35 accurately abuts against the side of the folded page.
[0042] The second pressing plate 35 is provided with a second guide rod 31, which is used to ensure the stability of the sliding of the second pressing rod 30.
[0043] In some further embodiments, the bottom of the second pressing rod 30 is provided with a hinged rod 32, the second pressing plate 35 is provided with a hinged ring 33, the hinged rod 32 is hingedly arranged with the hinged ring 33, and the hinged rod 32 is provided with a torsion spring 34 for driving the bottom of the second pressing plate 35 to move towards the main body direction of the carton 7; the second pressing rod 30 is provided with a limiting column 300 for limiting the rotation of the second pressing plate 35.
[0044] The hinged rod 32 at the bottom of the second pressing rod 30 is hingedly arranged with the hinged ring 33 on the second pressing plate 35, forming a rotatable connection structure. One end of the torsion spring 34 on the hinged rod 32 is connected to the hinged rod 32, and the other end is connected to the second pressing plate 35. The elastic force of the torsion spring 34 always drives the bottom of the second pressing plate 35 to rotate towards the main body direction of the carton 7, ensuring that the bottom of the second pressing plate 35 can have a tendency to press down and fold the distal hinged end of the folded page.
[0045] The limiting column 300 on the second pressing rod 30 is located on the side of the second pressing plate 35 away from the carton 7, and is used to limit the excessive rotation of the second pressing plate 35 under the action of the torsion spring 34 when the second pressing plate 35 does not contact the folded page.
[0046] In some further embodiments, the side of the second pressing plate 35 facing the carton 7 is provided with a third pressing plate 36, and the side of the second pressing plate 35 away from the carton 7 is provided with a sliding rod 37. The sliding rod 37 is provided with a third spring 370, the third pressing plate 36 is provided with a connecting rod 39, and the connecting rod 39 is in sliding cooperation with the sliding rod 37 through a slot provided on the second pressing plate 35.
[0047] The third pressing plate 36 on the side of the second pressing plate 35 facing the carton 7 can be made of flexible rubber material, and the sliding rod 37 on the side of the second pressing plate 35 away from the carton 7 is arranged in the vertical direction. The third spring 370 is sleeved on the sliding rod 37 and abuts against the mounting handle 38 and the connecting rod 39 at both ends.
[0048] The connecting rod 39 on the third pressing plate 36 passes through the slot of the second pressing plate 35 and is in sliding cooperation with the end of the sliding rod 37. The slot extends in the height direction of the second pressing plate 35, providing vertical movement space for the connecting rod 39. When the second pressing plate 35 abuts against the folded page, the third pressing plate 36 will simultaneously press down the top of the carton 7, ensuring that the folded page is bent more solidly.
[0049] In some further embodiments, the number of abutting mechanisms is two groups, and the two groups of abutting mechanisms are symmetrically arranged along the conveying direction of the carton 7. One group of abutting mechanisms is used to abut against the first time sequence sealing folded page 70 at one end of the carton 7, and the other group of abutting mechanisms is used to abut against the second time sequence sealing folded page 71 at the other end.
[0050] The two sets of abutting mechanisms are symmetrically arranged along the conveying direction of the carton 7, and correspond to the first and second time sequence sealing flaps 70 and 71 (the time sequence difference refers to the order in which the flaps need to be pressed) at the two ends of the carton 7. The abutting mechanism close to the upstream of the conveying line 1 first acts on the first time sequence flap, and completes the preliminary pressing; when the carton 7 continues to convey to the position of the downstream abutting mechanism, the downstream mechanism acts on the second time sequence flap again. The symmetric arrangement realizes the time sequence pressing or simultaneous pressing of the flaps at the two ends of the carton 7, and can adapt to the sealing requirements at the two ends without additional adjustment of the equipment position, which greatly improves the pressing efficiency compared with the back-and-forth operation mode of a single set of mechanism, and the synchronous correction and pressing at the two ends can further ensure the posture stability of the carton 7.
[0051] In some further embodiments, an auxiliary limiting mechanism 6 is further included, and the auxiliary limiting mechanism 6 is located downstream corresponding to the abutting second time sequence sealing flap 71. The auxiliary limiting mechanism 6 includes an arc-linear guide rail 61, a rotating roller 60, and a blocking rod 65; the sliding column 640 is slidably arranged on the arc-linear guide rail 61, the guide sleeve 63 is arranged on the rotating roller 60, the guide column 64 is arranged on the sliding column 640 and slidably matched with the guide sleeve 63, and the fourth spring 630 is arranged in the guide sleeve 63; the blocking rod 65 is connected with the sliding column 640 through the connecting arm 62. The arc segment of the arc-linear guide rail 61 is located more downstream of the conveying line 1 than the linear segment.
[0052] The auxiliary limiting mechanism 6 is located downstream of the abutting mechanism corresponding to the second time sequence sealing flap 71, the arc segment of the arc-linear guide rail 61 is bent upward, the sliding column 640 is slidably embedded in the arc-linear guide rail 61, the guide column 64 on the rotating roller 60 is slidably matched with the guide sleeve 63 on the sliding column 640, and the fourth spring 630 in the guide sleeve 63 is connected at both ends with the guide column 64 and the bottom of the guide sleeve 63, respectively. The blocking rod 65 is fixed with the sliding column 640 through the connecting arm 62, and can be made of plastic or rubber.
[0053] The rotating roller 60 is driven by the motor 600, when the carton 7 with the first time sequence sealing flap 70 sealed reaches the working position of the downstream abutting mechanism, the rotating roller 60 rotates, drives the sliding column 640 to slide from the arc segment to the linear segment, so that the blocking rod 65 moves downward and approaches the first time sequence sealing flap 70 that has been sealed and pressed, thereby realizing secondary insurance sealing and pressing, ensuring the stability of the sealing, and further improving the sealing quality.
[0054] The carton 7 runs on the roller conveying line 1.
[0055] The number of arc-linear guide rails 61 is two, and both are arranged on the roller conveying line 1. The side facing each other of the two arc-linear guide rails 61 is provided with a sliding groove 610 for slidably matching the end of the sliding column 640.
[0056] The roller conveying line 1 is further provided with a blocking mechanism driven by a pneumatic cylinder to ensure accurate positioning of the two abutting positions.
[0057] The specific blocking mechanism can be a blocking plate arranged at the moving end of the pneumatic cylinder.
[0058] It should be noted that the movement of each of the above-mentioned automation mechanisms is realized through a specific PLC program for orderly operation and relies on the signal feedback of the sensor, which is very common in the automation industry and is prior art, and will not be described in detail in this embodiment.
[0059] Obviously, the above-mentioned embodiments are only examples for clear illustration, rather than limitation of the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
