DETAILED DESCRIPTION

[0020] In order to more clearly understand the above objectives, features and advantages of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings of the embodiments of the present application. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] It should be noted that when one component is considered to be "connected" to another component, it can be directly connected to the other component or a middle component can exist at the same time.

[0022] [First Embodiment]

[0023] The box folding machine 1000 is a mechanical device for automatically folding a box 2000, which includes an infeed unit 100, a primary forming unit 300, a secondary forming unit 500, and a discharge unit 700. The semi-finished product of the box 2000 is fed from the infeed unit 100, and each unit is mounted on a workbench 900.

[0024] The box 2000 suitable for the present application can be of existing configuration, generally in the form of a box having a bottom surface and side surfaces connected to the bottom surface, and can be with or without a cover.

[0025] When the folding machine 1000 is in operation, the semi-finished box 2000 in flat state is fed from the feeding unit 100, and after being folded and formed by the primary forming unit 300 and the secondary forming unit 500, the finished box 2000 is discharged from the discharging unit 700.

[0026] The feeding unit 100 is the starting point of the folding machine 1000, and is located at the central position P0 of the folding machine 1000. It is used to place and position the semi-finished box 2000 in flat state. Even if multiple semi-finished boxes 2000 are stacked together, it can ensure that the semi-finished box 2000 is accurately and stably placed at the designated position. The feeding unit 100 is vertically arranged, and multiple semi-finished boxes 2000 to be stacked are stacked inside.

[0027] The primary forming unit 300 is fixedly installed on the desktop of the workbench 900 and is located below the feeding unit 100. A through hole is provided through the desktop of the workbench 900, and the through hole is located directly below the feeding unit 100. The primary forming unit 300 is used to preliminarily fold the semi-finished box 2000, so that the four side surfaces of the box 2000 stand up. The primary forming unit 300 includes a primary forming part 310 and a pull-down part 320. The primary forming part 310 can stand up the side surface of the semi-finished box 2000, and the pull-down part 320 pulls down the semi-finished box 2000 placed by the feeding unit 100 to the primary forming part 310.

[0028] The primary forming part 310 has a main body 315 and a translation mechanism 316. The main body 315 is a plate body with a rectangular structure, and a first shaping groove 311 and a second shaping groove 312 are formed along the length direction thereof. The first shaping groove 311 and the second shaping groove 312 match the shape of the bottom surface of the box 2000. The bottom surface of the first shaping groove 311 and the second shaping groove 312 is provided with an opening 313. The opening 313 is in communication with the through hole of the workbench 900, and is used to pass through the pull-down part 320 to obtain a semi-finished box 2000. Moreover, a plurality of shaping members 314 are arranged on the upper surface of the main body 315. The shaping members 314 vertically extend towards the upper side (i.e. the side of the feeding unit 100), and the first shaping groove 311 is formed by a part of the plurality of shaping members 314, and the second shaping groove 312 is formed by another part of the plurality of shaping members 314.

[0029] The end face of the shaping member 314 facing the corresponding first shaping groove 311 or second shaping groove 312 has a shaping face 3141. The shaping face 3141 is perpendicular to the upper surface of the main body 315, and a plurality of shaping faces 3141 surround the first shaping groove 311, for contacting the side surface of the box 2000, thereby ensuring the accuracy and consistency of the semi-finished product of the box 2000 during the folding process.

[0030] The shaping member 314 can also have a guide face 3142 connected to the shaping face 3141. The guide face 3142 is connected above the shaping face 3141, and as it moves away from the shaping face 3141, it approaches the end face on the opposite side of the shaping face 3141, thereby guiding the semi-finished product of the box 2000 to be folded into the first shaping groove 311 and the second shaping groove 312 without deviation.

[0031] The translation mechanism 316 is installed on the workbench 900 and extends along the length direction of the main body 315, with one end fixedly connected to the main body 315 and the other end fixedly connected to the workbench 900. The translation mechanism 316 is, for example, a structure that can extend and retract in the left-right direction, such as a pneumatic cylinder.

[0032] Under the drive of the translation mechanism 316, the main body 315 reciprocates along its length direction, so that the main body 315 can reciprocate between the first position P1 and the second position P2. Figure 3 In the front view, the first position P1 is located to the left of the central position P0, and the second position P2 is located to the right of the central position P0.

[0033] When the translation mechanism 316 moves the main body 315 to the first position P1, the first shaping groove 311 is located at the first position P1, and the second shaping groove 312 is located at the central position P0. On the other hand, when the translation mechanism 316 moves the main body 315 to the second position P2, the second shaping groove 312 is located at the second position P2, and the first shaping groove 311 is located at the central position P0.

[0034] The pull-down part 320 is located below the primary forming part 310 and at the central position P0, and has a suction part 321, a guide rod 322, and a lifting mechanism 323.

[0035] The suction part 321 is provided at the upper end of the pull-down part 320, and the suction part 321 can adsorb the semi-finished product of the box 2000. The guide rod 322 extends in the up-down direction and is fixed to the workbench 900. The suction part 321 can be connected to the upper end of the guide rod 322 and provide suction force through the pipeline built in the guide rod 322. The lifting mechanism 323 is, for example, a structure that can extend and retract in the up-down direction, such as a pneumatic cylinder.

[0036] Under the drive of the lifting mechanism 323, the pull-down part 320 can pass through the opening 313 of the primary forming part 310 and reciprocate up and down between the feeding unit 100 and the primary forming part 310.

[0037] When the pull-down part 320 is lifted, it passes through the opening 313 of the primary forming part 310 and contacts the semi-finished product of the lowermost box 2000 in the feeding unit 100 and is adsorbed by the adsorption part 321.

[0038] When the pull-down part 320 is lowered, the state of the adsorption part 321 adsorbing the semi-finished product of the box 2000 is maintained, the semi-finished product of the box 2000 is pulled down, and the pull-down part 320 releases the semi-finished product of the box 2000 before passing through the opening 313 of the primary forming part 310, so that the semi-finished product of the box 2000 is accommodated in the first sizing groove 311 or the second sizing groove 312 located at the central position P0. During the pulling-down process, the part of the semi-finished product of the box 2000 that overlaps with the bottom surface of the first sizing groove 311 or the second sizing groove 312 is accommodated as the bottom surface of the box 2000 in the bottom surface of the first sizing groove 311 or the second sizing groove 312, and the excess part is first lifted by the guide surface 3142 of the plurality of sizing members 314 and then folded by the sizing surface 3141, so that all the side surfaces of the box 2000 are folded and stand up.

[0039] The secondary forming unit 500 is provided with two, one located at the first position P1 and the other located at the second position P2, and the two secondary forming units 500 are the same in structure. The secondary forming unit 500 has a pushing edge part 510 and a pressing edge part 520.

[0040] The pushing edge part 510 is arranged substantially horizontally with the primary forming part 310 and is used to bend a part of the side surface of the box 2000 inward.

[0041] The pushing edge part 510 has left and right pushing edge rods 511A and 511B and left and right pushing mechanisms 521A and 521B. The left and right pushing edge rods 511A and 511B extend toward the front-back direction of the box folding machine 1000 and face each other and can move close to each other under the drive of the left and right pushing mechanisms 521A and 521B. The left and right pushing edge rods 511A and 511B are located slightly higher than the main body 315 of the primary forming part 310 and can push the two side surfaces of the box 2000 placed in the first sizing groove 311 and the second sizing groove 312, so that a part of the two side surfaces of the box 2000 facing each other are bent inward.

[0042] When the pushing edge is performed, the left pushing mechanism 521A moves to the right side and the right pushing mechanism 521B moves to the left side, so that the left and right pushing edge rods 511A and 511B push the opposite two side surfaces of the box 2000 to move close to each other and slightly inward.

[0043] When the pushing edge is completed, the left pushing mechanism 521A is reset and moves toward the left side, and the right pushing mechanism 521B is reset and moves toward the right side.

[0044] The edge-pressing part 520 is arranged above the pushing edge part 510, and is used to fold a part of the side of the box 2000 inwardly into the box 2000, so that the folded-in part buckles the side and its adjacent side into shape, in other words, all the sides of the box 2000 remain standing.

[0045] The edge-pressing part 520 has a guide rod 521, a downward-pressing mechanism 522, an inward-expanding mechanism 523, an edge-pressing head 524, and a suction head 525.

[0046] The guide rod 521 extends along the up-and-down direction, and is installed on the workbench 900.

[0047] The downward-pressing mechanism 522 is, for example, a structure containing a pneumatic cylinder and the like, and is capable of extending and retracting along the up-and-down direction.

[0048] The inward-expanding mechanism 523 is, for example, a structure containing a pneumatic cylinder and the like, and is capable of extending and retracting along the left-and-right direction.

[0049] The edge-pressing head 524 and the suction head 525 are arranged at the lower end of the edge-pressing part 520. The edge-pressing head 524 is provided with two in the left-and-right direction (i.e. the length direction of the main body 315 of the one-time forming part 310). The suction head 525 is used to suck the finished product of the box 2000 and carry it to the discharging unit 700.

[0050] Under the drive of the downward-pressing mechanism 522, the edge-pressing head 524 moves along the guide rod 521 toward the lower side, and when it moves to a specified position, the inward-expanding mechanism 523 drives the two edge-pressing heads 524 to expand from inside toward outside. Specifically, the edge-pressing head 524 located on the left side moves toward the left side, and the edge-pressing head 524 located on the right side moves toward the right side, and the two edge-pressing heads 524 expand toward the direction of moving away from each other.

[0051] When the edge-pressing is performed, the downward-pressing mechanism 522 drives the edge-pressing head 524 to descend, and in the process, the edge-pressing head 524 contacts the side of the box 2000 and drives the side of the box 2000 to further bend into a folded state. Then, the inward-expanding mechanism 523 drives the edge-pressing head 524 to expand from inside toward outside and press on the side in the folded state, so that the folded state of the side of the box 2000 is maintained, and thus the finished product of the box 2000 is obtained.

[0052] After the completion of the crimping, the inner-expanding mechanism 523 drives the crimping head 524 to reset and move from the outside to the inside. And the suction head 525 suctions the bottom surface of the box 2000. In this state, the lower-pressing mechanism 522 drives the crimping head 524 to rise, and the box 2000 is taken away from the first shaping groove 311 and the second shaping groove 312. And when the discharging unit 700 moves to the lower side, the finished product of the box 2000 is released.

[0053] The discharging unit 700 is provided with two, and the two discharging units 700 are the same in structure. One discharging unit 700 is located at the first position P1, and is responsible for discharging the finished product of the box 2000 received in the first shaping groove 311 at the first position P1. The other discharging unit 700 is located at the second position P2, and is responsible for discharging the finished product of the box 2000 received in the second shaping groove 312 at the second position P2.

[0054] The discharging unit 700 has a conveying belt 710, a mounting portion 720, and a moving mechanism 730. The conveying belt 710 is used to discharge the finished product of the box 2000 placed thereon to the outside of the workbench 900. The moving mechanism 730 is, for example, a structure capable of extending and retracting in the front-back direction, such as a pneumatic cylinder. One end of the mounting portion 720 is fixed to the conveying belt 710, and the other end is fixed to the moving end of the moving mechanism 730, such as the output end of the pneumatic cylinder. Under the drive of the moving mechanism 730, the conveying belt 710 moves together with the mounting portion 720 in the front-back direction.

[0055] Before the finished product of the box 2000 is completed and is suctioned by the suction head 525 and taken to the upper side of the conveying belt 710, the suction head 525 keeps suctioning the finished product of the box 2000, and the conveying belt 710 is located at the rear side. When the finished product of the box 2000 is higher than the conveying belt 710, the conveying belt 710 is moved to the front side by the moving mechanism 730 and is located directly below the suction head 525, and then the suction head 525 releases the finished product of the box 2000, so that the finished product of the box 2000 falls on the conveying belt 710. In addition, the suction head 525 can be slightly lowered so that the bottom surface of the box 2000 approaches or contacts the conveying belt 710, and then the finished product of the box 2000 is released.

[0056] In addition, it can be understood that the discharging unit 700 and the suction head 525 can be omitted, and the finished product of the box 2000 can be taken out of the box folding machine 1000 by human operation or other ways.

[0057] In the workbench 900, the feeding unit 100 is installed on the upper layer (for example, the upper surface), a part of the primary forming unit 300 is installed on the middle layer, another part is installed on the lower layer, the secondary forming unit 500 and the discharging unit 700 are installed on the middle layer. The semi-finished product of the flat state of the box 2000 is fed from the feeding unit 100 on the upper layer, is taken to the middle layer by the primary forming unit 300, the first forming, the second forming and the discharging are completed in the middle layer, the travel route of the semi-finished product of the box 2000 is simple, and the integration of the box folding machine 1000 can be high.

[0058] Thus, in the box folding machine 1000, for the box 2000, the semi-finished product of the flat state of the box 2000 as shown in (a) of FIG. 1 is fed from the feeding unit 100; then the semi-finished product of the box 2000 is erected on all sides as shown in (b) of FIG. 1 by the primary forming unit 300; then the two sides opposite to each other of the semi-finished product of the box 2000 are folded inward as shown in (c) of FIG. 1 by the pushing edge part 510 of the secondary forming unit 500; then the sides are pressed down and become the folded state as shown in (d1) of FIG. 1 by the pressing edge part 520 of the secondary forming unit 500, and the sides of the box 2000 are further pressed by the pressing edge part 520 to become the folded state as shown in (d2) of FIG. 1, at this time, the folding process in the box folding machine 1000 is completed, and the finished product of the box 2000 is obtained; finally, the finished product of the box 2000 is discharged in the same state as (d2) of FIG. 1, that is, the state of (e) of FIG. 1. Thus, the cooperation of each unit of the box folding machine 1000 realizes the automatic folding and manufacturing of the box 2000. Figure 12 Figure 12 Figure 12 Figure 12 Figure 12 Figure 12 Figure 12

[0059] ​​​​​​​Moreover, in the box folding machine 1000, for the folding processes at the central position P0, the first position P1 and the second position P2, when the translation mechanism 316 drives the main body 315 to move to the first position P1, the first shaping groove 311 is located at the first position P1, the secondary forming unit 500 at the first position P1 performs the edge pushing action and the edge pressing action on the semi-finished product of the box 2000 in the first shaping groove 311, at the same time, the second shaping groove 312 is located at the central position P0, at this time, the pull-down part 320 moves the semi-finished product of the box 2000 placed by the feeding unit 100 to the second shaping groove 312, the secondary forming unit 500 at the second position P2 does not perform the edge pushing action and the edge pressing action; when the translation mechanism 316 drives the main body 315 to move to the second position P2, the second shaping groove 312 is located at the second position P2, the secondary forming unit 500 at the second position P2 performs the edge pushing action and the edge pressing action on the semi-finished product of the box 2000 in the second shaping groove 312, at the same time, the first shaping groove 311 is located at the central position P0, at this time, the pull-down part 320 moves the semi-finished product of the box 2000 placed by the feeding unit 100 to the first shaping groove 311, the secondary forming unit 500 at the first position P1 does not perform the edge pushing action and the edge pressing action. In this way, the forming of two boxes 2000 can be performed simultaneously on the double stations, so that the box folding machine 1000 can efficiently realize the folding of the box 2000. In addition, the discharge of the finished product of the box 2000 can also be performed simultaneously by the feeding unit 100 at the position where the secondary forming unit 500 does not perform the edge pushing action and the edge pressing action, which can further improve the efficiency of the box folding machine 1000.

[0060] The above merely describes specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which shall be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
