DETAILED DESCRIPTION

[0017] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0018] The packaging box 1 (carton) for packaging the battery piece packaging box needs to press the short cover of the packaging box 1 downward after the battery piece packaging box is taken out, then press the long cover of the packaging box 1 downward and make the long cover press above the short cover, then use the adhesive tape to paste the two long covers together to realize the sealing of the box. However, the sealing of the packaging box 1 is generally realized manually at present, which not only increases the labor cost, but also is low in working efficiency.

[0019] As shown in Figure 1 , Figure 2 , in order to solve the above problems, the embodiment of the application provides a box recycling device, which comprises a lifting transmission mechanism 2, a short cover flanging mechanism 3 and a long cover flanging mechanism 4.

[0020] Specifically, as shown in Figure 3 , the lifting transmission mechanism 2 comprises a lifting assembly 21 and a transverse transmission assembly 22, and the lifting assembly 21 is fixed on a gantry (not shown in the figure). The transverse transmission assembly 22 is connected with the lifting assembly 21, and the lifting assembly 21 drives the transverse transmission assembly 22 to move up and down. As shown in Figure 2 , the short cover flanging mechanism 3 is arranged on a recycling bottom plate, and the short cover flanging mechanism 3 comprises a first flanging assembly 31 and a second flanging assembly 32, and the first flanging assembly 31 and the second flanging assembly 32 are arranged in sequence along the transmission direction of the transverse transmission assembly 22. As shown in Figure 4 , Figure 5 , the first flanging assembly 31 comprises a first flanging pressing plate 311, and the short cover on the left side is pressed downward by the first flanging pressing plate 311 during the movement of the packaging box 1 to the left; the second flanging assembly 32 comprises a second flanging pressing plate 321, and the short cover on the right side is pressed downward by the second flanging pressing plate 321 during the conveying of the packaging box 1 to the right. As shown in Figure 2 , Figure 6 , the long cover flanging mechanism 4 is arranged on the gantry, and the long cover flanging mechanism 4 comprises two oppositely arranged pressing push rods 41. The two pressing push rods 41 are located on the opposite sides of the second flanging pressing plate 321, and the long covers on the two sides are pressed downward by the two pressing push rods 41 during the conveying of the packaging box 1 to the right.

[0021] The empty box recycling device of the embodiment of the present application is used in the following way: the empty packaging box 1 of the previous process is first conveyed to the transverse conveying assembly 22, then the packaging box 1 is moved downward by the lifting assembly 21 to the height of the first flange pressing plate 311. Then the transverse conveying assembly 22 moves the packaging box 1 to the left, and the left short cover is pressed downward by the first flange pressing plate 311 during the movement. Then the transverse conveying assembly 22 moves the packaging box 1 to the right, and the right short cover is pressed downward by the second flange pressing plate 321. After the short cover is pressed downward, the packaging box 1 continues to be conveyed to the right, and the two long covers of the packaging box 1 are pressed downward by the two downward pressing push rods 41. The empty box recycling device of the embodiment of the present application can automatically realize the pressing and closing of the short cover and the long cover of the packaging box 1, realize the sealing operation of the packaging box 1, save the labor cost, and improve the work efficiency.

[0022] In an embodiment, in order to realize the lifting and conveying of the packaging box 1, the lifting assembly 21 can be an existing linear module, and the transverse conveying assembly 22 is connected to the linear module through a sliding block, so as to drive the transverse conveying assembly 22 to move upward or downward. The transverse conveying assembly 22 can be an existing conveying belt for conveying materials, which is driven by a motor to move the belt and thus move the packaging box 1 located thereon. The moving direction of the packaging box 1 is changed by changing the rotating direction of the output end of the motor.

[0023] In an embodiment, as shown in Figure 2 、 Figure 4 In order to press the short cover downward, the first flange assembly 31 is two, and the two first flange assemblies 31 are oppositely arranged, and one of the first flange assemblies 31 is located between the second flange assembly 32 and the other first flange assembly 31. The first flange assembly 31 further comprises a flange driving cylinder 312 connected to the first flange pressing plate 311, and the flange driving cylinder 312 drives the first flange pressing plate 311 to move toward the middle part of the transverse conveying assembly 22. Preferably, the upper part of the first flange pressing plate 311 has a flange baffle 313 inclined upward, and the first flange pressing plate 311 and the flange baffle 313 can be an integral structure.

[0024] During the movement of the transverse conveying assembly 22 to the left, the flange driving cylinder 312 located on the left side drives the first flange pressing plate 311 to move toward the middle part of the transverse conveying assembly 22, and the left short cover is pressed downward by the first flange pressing plate 311.

[0025] As shown in Figure 1 、 Figure 2As shown, in order to avoid the long cover being folded outwardly during the movement of the packaging box 1, in an embodiment, the empty box recycling device further comprises a blocking and supporting mechanism 6 arranged on the recycling base plate. The blocking and supporting mechanism 6 comprises two oppositely arranged blocking and supporting assemblies 61, and the two blocking and supporting assemblies 61 are respectively located on the opposite sides of the transverse conveying assembly 22. During the movement of the packaging box 1 on the transverse conveying assembly 22, the long cover is blocked and supported by the two blocking and supporting assemblies 61, so as to avoid being folded outwardly. The blocking and supporting assembly 61 can make the long cover in a vertical state or be folded inwardly by a certain angle to the packaging box 1.

[0026] Further, as shown in the drawings, Figure 5 The blocking and supporting assembly 61 is located between the first edge folding assembly 31 and the second edge folding assembly 32, and the blocking and supporting assembly 61 is located below the first edge folding assembly 31. The blocking and supporting mechanism 6 comprises a blocking and supporting driving cylinder 611 and a blocking and supporting plate 612, the blocking and supporting driving cylinder 611 is connected with the blocking and supporting plate 612, and the blocking and supporting driving cylinder 611 drives the blocking and supporting plate 612 to move towards the middle part of the transverse conveying assembly 22. When the packaging box 1 is located on the transverse conveying assembly 22, the blocking and supporting driving cylinder 611 drives the blocking and supporting plate 612 to move towards the middle part of the transverse conveying assembly 22, so that the two long covers of the packaging box 1 are in contact with the blocking and supporting plate 612, thereby avoiding the long cover being folded outwardly. The blocking and supporting plate 612 can be provided with a corresponding length according to the requirement. The blocking and supporting plate 612 has an arc-shaped plate extending outwardly.

[0027] Since the first edge folding assembly 31 has two, after the short cover on the right side is in contact with the first edge folding pressing plate 311 of the first edge folding assembly 31 on the right side, the short cover on the right side can be blocked and supported by the first edge folding pressing plate 311, so as to avoid being folded outwardly. The first edge folding pressing plate 311 can block and support the short cover on the right side, so that the short cover on the right side is in a vertical state or is folded inwardly by a certain angle to the packaging box 1.

[0028] In an embodiment, the length of the transverse conveying assembly 22 can be slightly longer than the length of the packaging box 1, and even if the packaging box 1 moves to the left, the short cover on the right side of the packaging box 1 can be in contact with the first edge folding pressing plate 311 on the right side. At this time, the short cover on the right side can be folded outwardly by a certain angle to the packaging box 1.

[0029] As shown in the drawings, Figure 1 , Figure 2As shown, in order to make the empty box recycling device applicable to the use of packaging boxes 1 of different sizes, a folding edge moving mechanism 7 is fixed on the recycling base plate 5. The folding edge moving mechanism 7 comprises a folding edge transverse moving assembly 71 and a folding edge longitudinal moving assembly 72, the folding edge transverse moving assembly 71 is connected with the folding edge longitudinal moving assembly 72, the folding edge longitudinal moving assembly 72 is connected with a folding edge fixed base 73, and the folding edge driving cylinder 312 of the two first folding edge assemblies 31 and the one block support driving cylinder 611 are both fixed on the folding edge fixed base 73 by bolts. The folding edge transverse moving assembly 71 can be fixed on the recycling base plate 5 by bolts.

[0030] Specifically, the folding edge transverse moving assembly 71 and the folding edge longitudinal moving assembly 72 can both be cylinders, which drive the first folding edge assembly 31 and the one block support assembly 61 to move in the transverse and longitudinal directions, so as to adjust the positions thereof.

[0031] In an embodiment, the folding edge moving mechanism 7 can be two, and the other folding edge moving mechanism 7 can be connected with the other block support assembly 61. Through the arrangement of the folding edge moving mechanism 7, the positions of the first folding edge assembly 31 and the block support assembly 61 can be adjusted, so as to be applicable to the use of packaging boxes 1 of different sizes.

[0032] After the short cover on the left side of the packaging box 1 is pressed down, the packaging box 1 is continuously moved to the right by the folding edge transverse moving assembly 71. In an embodiment, as shown, Figure 1 A conveying mechanism 8 is also arranged on the recycling base plate 5, the feeding end of the conveying mechanism 8 is connected with the discharging end of the transverse transmission assembly 22, the transverse transmission assembly 22 can directly convey the packaging box 1 to the conveying mechanism 8, and the packaging box 1 is continuously conveyed to the right by the conveying mechanism 8.

[0033] The second folding edge assembly 32 is located above the feeding end of the conveying mechanism 8, and after the packaging box 1 is conveyed to the conveying mechanism 8, the short cover on the right side of the packaging box 1 is pressed down by the second folding edge assembly 32.

[0034] As shown, Figure 2 The short cover folding edge mechanism 3 also comprises a folding edge support rod 33 and a folding edge height adjusting plate 34, and the folding edge support rod 33 can be fixed on the gantry by bolts. The folding edge height adjusting plate 34 is movably connected with the folding edge support rod 33. Specifically, an adjusting groove 35 can be formed in the height direction of the folding edge height adjusting plate 34, and an adjusting bolt is arranged in the adjusting groove 35. After the adjusting bolt passes through the adjusting groove 35, the adjusting bolt is threadedly connected with the folding edge support rod 33. When the adjusting bolt is tightened, the folding edge height adjusting plate 34 and the folding edge support rod 33 can be fixed; when the bolt is loosened, the folding edge height adjusting plate 34 can be moved up and down, so as to adjust the height of the folding edge height adjusting plate 34 and the second folding edge pressing plate 321.

[0035] The second folding pressure plate 321 is connected to the folding height adjustment plate 34 by screws. The cross-section of the end of the second folding pressure plate 321 closest to the first folding pressure plate 311 is arc-shaped. There can be four height adjustment plates, and each of the four height adjustment plates is connected to the second folding pressure plate 321.

[0036] During the process of conveying the packaging box 1 to the conveying mechanism 8, such as Figure 5 As shown, one end of the second folding edge pressure plate 321, which has an arc-shaped cross-section, first contacts the short cover on the right side of the packaging box 1. As the packaging box 1 is conveyed, the second folding edge pressure plate 321 presses the short cover downwards. Then, the packaging box 1 continues to be conveyed to the right, and the two downward push rods 41 press down the two long covers, as shown. Figure 7 As shown, the downward push rod 41 has an approximately L-shaped structure.

[0037] like Figure 2 As shown, to secure the two pressing push rods 41, the long cover folding mechanism 4 also includes a pressing support rod 42, which can be fixed to the gantry frame with screws. Both ends of the pressing support rod 42 are respectively fixed with push rod fixing seats 43 using screws, and the tops of the two pressing push rods 41 are respectively fixed to the two push rod fixing seats 43. Specifically, the pressing push rods 41 can be fixed to the push rod fixing seats 43 with screws; alternatively, a mounting groove can be provided on the push rod fixing seat 43, and the tops of the pressing push rods 41 can be directly inserted into the mounting groove for fixation.

[0038] like Figure 1 As shown, the empty box recycling device also includes a flattening mechanism 9, which is fixed to the gantry. After the long lid of the packaging box 1 is pressed down, the packaging box 1 is then driven by the conveying mechanism 8 to continue to be conveyed to the right, and after passing the flattening mechanism 9, the flattening mechanism 9 flattens the long lid.

[0039] like Figure 2 , Figure 9 As shown, the flattening mechanism 9 includes two opposing flattening plates 91, located above the conveying mechanism 8. The pressing push rod 41 and the flattening plates 91 are sequentially arranged along the conveying direction of the conveying mechanism 8. To fix the flattening plates 91, the flattening mechanism 9 also includes plate support rods 92 and four plate fixing plates 93. The plate support rods 92 are fixed to the gantry frame with screws, and the four plate fixing plates 93 are movably connected to the plate support rods 92. The four flattening plates 91 are connected to the two plate support rods 92 with screws. The connection method between the flattening fixing plates 93 and the flattening support rods 92 is the same as the connection method between the folding height adjustment plate 34 and the folding support rod 33, allowing the flattening fixing plates 93 to move upwards or downwards relative to the flattening support rods 92 to adjust their position. This makes the flattening mechanism 9 suitable for use with packaging boxes 1 of different sizes.

[0040] In an embodiment, as shown in Figure 10 The empty box recycling device further comprises a tape sticking mechanism 10, and the packaging box 1 is conveyed to the lower side of the tape sticking mechanism 10 after passing through the flattening mechanism 9. The tape sticking mechanism 10 is connected with a tape sticking moving mechanism 11, and the tape sticking moving mechanism 11 is fixed on the gantry. The tape sticking moving mechanism 11 drives the tape sticking mechanism 10 to move in the horizontal and vertical directions, and the tape sticking mechanism 10 is used for sticking tapes on the two long covers of the packaging box 1.

[0041] The tape sticking moving mechanism comprises a tape sticking horizontal moving assembly 110 and a tape sticking vertical moving assembly 111, and the tape sticking horizontal moving assembly 110 and the tape sticking vertical moving assembly 111 are connected through a sliding block. The tape sticking mechanism 10 is connected with the tape sticking horizontal moving assembly 110 through a sliding block. Preferably, the tape sticking horizontal moving assembly and the tape sticking vertical moving assembly can be existing linear modules. The tape sticking mechanism 10 can be any existing tape sticking mechanism or tape sticking device, which can stick tapes on the packaging box 1. The two ends of the tape are connected with the two long covers respectively, so as to stick the two long covers together. After the tapes are stuck on the packaging box 1 to realize the sealing of the packaging box 1, the packaging box 1 is continuously conveyed to the next process.

[0042] Since the packaging box 1 is light, as shown in Figure 2 、 Figure 8 In order to better control the conveying, the conveying mechanism 8 comprises two oppositely arranged belt conveying assemblies 81 and two oppositely arranged roller conveying assemblies 82. The two roller conveying assemblies 82 are located between the two belt conveying assemblies 81, and the two belt conveying assemblies 81 drive the packaging box 1 to move on the two roller conveying assemblies 82.

[0043] In order to realize the movement of the packaging box 1, the belt conveying assembly 81 comprises a conveying frame body 811, a conveying driving motor 812, a conveying driving wheel 813, a conveying driven wheel 814 and a conveying belt 815 arranged on the conveying frame body 811. The output end of the conveying driving motor 812 is connected with the conveying driving wheel 813, the conveying driving wheel 813 is connected with the conveying driven wheel 814 through the conveying belt 815, and the conveying belt 815 is tightly attached to the packaging box 1. After the conveying driving motor 812 is started, the conveying driving motor 812 drives the conveying driving wheel 813 to rotate, and the conveying driving wheel 813 drives the conveying driven wheel 814 to rotate through the conveying belt 815. Since the conveying belt 815 is tightly attached to the packaging box 1, the packaging box 1 can be conveyed to the right through the friction between the conveying belt 815 and the packaging box 1.

[0044] In order to make the conveying mechanism 8 applicable to the use of packaging boxes 1 of different sizes, the conveying mechanism 8 further comprises two conveying position adjusting assemblies 83. The conveying position adjusting assemblies 83 are fixed on the recycling bottom plate 5, and the two conveying position adjusting assemblies 83 are connected with the two conveying frame bodies 811 respectively, and the two conveying frame bodies 811 can move towards or away from each other through the two conveying position adjusting assemblies 83.

[0045] Further, the conveying position adjusting assembly 83 comprises an adjusting slide rail 831 and an adjusting base 832. The adjusting slide rail 831 is fixed on the recycling bottom plate 5 through screws, and the adjusting base 832 is connected with the adjusting slide rail 831 through a sliding block. A plurality of adjusting holes are formed on the adjusting slide rail 831, and a bolt is installed on the sliding block and can be threadedly connected with any one of the adjusting holes. The conveying frame body 811 is connected with the adjusting base 832 through screws.

[0046] When it is necessary to adjust the position of the conveying frame body 811, the bolt can be screwed out of the adjusting hole, and then the sliding block is moved. When the sliding block is moved to a predetermined position, the bolt is tightened to be threadedly connected with the adjusting hole on the adjusting slide rail 831. Through the arrangement of the conveying position adjusting assembly 83, the distance between the two conveying belts 815 can be adjusted, so as to be applicable to the use of packaging boxes 1 of different sizes, and the conveying belts 815 can drive the packaging boxes 1 to realize conveying.

[0047] A plurality of rotating rollers 821 are arranged on the roller assembly 82, and the bottom of the packaging box 1 is located on the plurality of rotating rollers 821 and drives the rotating rollers 821 to rotate in the process of conveying the packaging box 1.

[0048] In use of the empty box recycling device, since the blocking and supporting assembly 61 is located below the first folding edge assembly 31, after the packaging box 1 is conveyed to the transverse conveying assembly 22, the packaging box 1 is first lifted upward by the lifting assembly 21, so that the short cover can be in contact with the first folding edge assembly 31. Then the packaging box 1 is moved to the left by the transverse conveying assembly 22, and the short cover on the left is pressed downward and closed by the first folding edge pressing plate 311 on the left. Then the packaging box 1 is moved downward by the lifting assembly 21, at this time, the height of the first folding edge pressing plate 311 is higher than the height of the box cover, and the long cover is in contact with the blocking and supporting assembly 61 and is blocked and supported by the blocking and supporting plate 612 of the blocking and supporting assembly 61, so as to avoid the long cover from being folded outward. In this state, even if the short cover on the right is folded outward, since the second folding edge pressing plate 321 is close to the position of the packaging box 1, the short cover will be in contact with the second folding edge pressing plate 321 in the process of being folded outward, so as to avoid further folding outward.

[0049] Then the packaging box 1 is conveyed to the conveying mechanism 8 by the transverse conveying assembly 22, and in the conveying process, the short covers on the right side are first closed by the second flanging plate 321. Then the conveying mechanism 8 continues to convey the packaging box 1 to the right, and when passing through the long cover flanging mechanism 4, the two long covers are pressed downward by the downward pressing rod 41, so that the two long covers are closed. Because the length of the blocking plate 612 is relatively long, the blocking plate 612 can still contact the long cover when the downward pressing rod 41 just contacts the long cover. Due to the arrangement of the blocking plate 612, after the two short covers are closed, the two long covers can be flipped to a certain angle inside the packaging box 1, so as to facilitate the subsequent downward pressing of the downward pressing rod 41.

[0050] After the packaging box 1 passes through the second flanging assembly 32, the packaging box 1 enters below the flattening plate 91, and the long cover and the short cover are flattened by the flattening plate 91. Then the packaging box 1 is continuously conveyed to the tape sticking mechanism 10, and the tape sticking mechanism 10 sticks the tape on the long cover, so as to realize the sealing of the packaging box 1. The existing conveying belt can be connected on the right side of the conveying mechanism 8, and the conveying of the packaging box 1 is realized through the conveying belt.

[0051] The embodiment of the present application can automatically realize the conveying of the packaging box 1, the closing, flattening and pasting of the long cover and the short cover, and the sealing of the packaging box 1, without manual participation, and the whole process is automatic, which improves the work efficiency and saves the labor cost.
