Description

Technical Field

[0001] This utility model relates to paper box forming, and features a specially designed edge-sealing design for the box opening. Background Technology

[0002] In the process of forming a cardboard box, cardboard (such as grey board) needs to be combined with face paper to form the box body. This requires binding the box opening by folding the face paper over the corresponding opening. Box opening binding can be performed either before the forming machine or within the forming machine itself. Some processes prevent binding in either of these two stages. Furthermore, binding the box opening within the forming machine also increases the number of steps and makes the structure more complex. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a box opening edge sealing device for paper boxes.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a box mouth edge-sealing device for a paper box, comprising a horizontal box body conveying mechanism, characterized in that: an upper and lower edge-sealing mechanism for sealing the upper and lower side walls of the box mouth and a left and right edge-sealing mechanism for sealing the left and right side walls of the box mouth are arranged along the conveying path of the horizontal box body conveying mechanism. The upper and lower edge-sealing mechanism comprises an upper edge-sealing component and a lower edge-sealing component. The upper edge-sealing component comprises an upper edge-sealing plate, and the lower edge-sealing component comprises a lower edge-sealing plate. The left and right edge-sealing mechanism comprises a left edge-sealing component and a right edge-sealing component. The left edge-sealing component comprises a left edge-sealing plate, and the right edge-sealing component comprises a right edge-sealing plate.

[0005] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0006] For example, the horizontal box conveying mechanism uses an intermittent horizontal box conveyor belt with a straight conveying path. The horizontal box conveying mechanism has a first edge-sealing station and a second edge-sealing station. One of the upper and lower edge-sealing mechanisms and the left and right edge-sealing mechanisms is located at the first edge-sealing station, and the other is located at the second edge-sealing station. The upper and lower edge-sealing mechanisms are arranged before or after the left and right edge-sealing mechanisms.

[0007] For example, the upper edge-binding component is correspondingly set on the upper side of the lower edge-binding component. The upper edge-binding plate is installed on the first lifting plate and is located on the lower side of the first lifting plate. The upper edge-binding plate moves downward with the first lifting plate and cooperates with the downward edge-flipping action. The upper edge-binding plate moves back and forth on the first lifting plate to cooperate with the edge-inserting action. The lower edge-binding plate is installed on the second lifting plate and is located on the upper side of the second lifting plate. The lower edge-binding plate moves upward with the second lifting plate and cooperates with the upward edge-flipping action. The lower edge-binding plate moves back and forth on the second lifting plate to cooperate with the edge-inserting action.

[0008] In addition, the first lifting plate includes a first pressing part that descends to press the outer wall of the box opening; the upper edge plate moves obliquely outward and forward on the first lifting plate to cooperate with the insertion edge, or the upper edge plate moves straight forward on the first lifting plate to cooperate with the insertion edge; the second lifting plate includes a second pressing part that rises to press the outer wall of the box opening; the lower edge plate moves obliquely outward and forward on the second lifting plate to cooperate with the insertion edge, or the lower edge plate moves straight forward on the second lifting plate to cooperate with the insertion edge; the first pressing part and the second pressing part cooperate to form a box opening clamping space.

[0009] For example, the left edge-binding component is positioned to the left of the right edge-binding component. The left edge-binding plate is mounted on the first sliding plate, which moves left and right. The left edge-binding plate is located to the right of the first sliding plate. The left edge-binding plate moves to the right with the first sliding plate and flips to the right. The left edge-binding plate moves back and forth on the first sliding plate to cooperate with the edge-insertion action. The right edge-binding plate is mounted on the second sliding plate, which moves left and right. The right edge-binding plate is located to the left of the second sliding plate. The right edge-binding plate moves to the left with the second sliding plate and flips to the left. The right edge-binding plate moves back and forth on the second sliding plate to cooperate with the edge-insertion action.

[0010] In addition, the first sliding plate includes a third pressing part that moves to the right for pressing the outer wall of the box opening, and the left edge plate moves obliquely outward and forward on the first sliding plate to cooperate with the insertion edge, or the left edge plate moves straight forward on the first sliding plate to cooperate with the insertion edge; the second sliding plate includes a fourth pressing part that moves to the left for pressing the outer wall of the box opening, and the right edge plate moves obliquely outward and forward on the second sliding plate to cooperate with the insertion edge, or the right edge plate moves straight forward on the second sliding plate to cooperate with the insertion edge; the third pressing part and the fourth pressing part cooperate to form a box opening clamping space.

[0011] In addition, the upper and lower edge-sealing mechanisms and the left and right edge-sealing mechanisms are located on the side of the conveying path. The first edge-sealing station and the second edge-sealing station are also equipped with box clamping and positioning devices, which include left and right clamping components.

[0012] Furthermore, the first edge-sealing station is equipped with a first bottom-pushing box body alignment device, and the second edge-sealing station is equipped with a second bottom-pushing box body alignment device. Each bottom-pushing box body alignment device includes a bottom-pushing movable component that pushes the bottom plate of the corresponding horizontal box body into place towards the box opening; the bottom-pushing movable component is also equipped with a box suction nozzle.

[0013] The horizontal box conveying mechanism can also have a labeling station, and between the labeling station and the second edge-wrapping station, there is a box-turning station for the horizontal box to turn up and down; the labeling station is equipped with a paper box labeling device, the box-turning station is equipped with a lifting frame, the lifting frame is equipped with a flipping frame, and the flipping frame is equipped with left and right clamping plates.

[0014] For example, the box input end of the horizontal box conveying mechanism is also equipped with a box picking and turning robot for switching the box to a horizontal posture for placement; the box picking and turning robot includes a box picking and placing component.

[0015] The beneficial effects of this utility model are that the box mouth sealing device of this paper box can cooperate with the corresponding sealing mechanism to seal the upper and lower edges and the left and right edges respectively during the horizontal paper box body conveying process, forming a pair-to-pair sealing structure (pair-to-pair pairing). The adjacent positions of the box mouth are less likely to interfere with each other during sealing, the sealing is relatively smooth, and the sealing operation is relatively more balanced and stable. The upper and lower sealing can be processed at the same time, and the left and right sealing can also be processed at the same time. The sealing is relatively efficient and can be adapted to complete the sealing of the box mouth after the paper box body is formed. It can be used for sealing selection of different paper box production processes. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Referring to the accompanying drawings, the box opening edge-sealing device in this embodiment includes a horizontal box body conveying mechanism 7 (the conveying can be in a straight line or a turntable manner). An upper and lower edge-sealing mechanism 5 and a left and right edge-sealing mechanism 6 are arranged along the conveying path of the horizontal box body conveying mechanism 7. The horizontal box body conveying mechanism 7 is used to cooperate in conveying the box body placed in a horizontal state so that the box stops at the corresponding position to cooperate with the upper and lower edge-sealing and left and right edge-sealing. The upper and lower edge-sealing mechanism 5 is used for edge-sealing the upper and lower side walls of the box opening, and the left and right edge-sealing mechanism 6 is used for edge-sealing the left and right side walls of the box opening.

[0029] The upper and lower edge binding mechanism 5 includes an upper edge binding assembly 1 and a lower edge binding assembly 2. The upper edge binding assembly 1 includes an upper edge binding plate 10, and the lower edge binding assembly 2 includes a lower edge binding plate 20. The upper edge binding plate 10 is used to bind the upper side wall of the box opening in the horizontal state, and the lower edge binding plate 20 is used to bind the lower side wall of the box opening in the horizontal state. The two work together to complete the upper and lower edge binding of the box opening.

[0030] The left and right edge binding mechanism 6 includes a left edge binding component 3 and a right edge binding component 4. The left edge binding component 3 includes a left edge binding plate 30, and the right edge binding component 4 includes a right edge binding plate 40. The upper edge binding plate 10 is used to bind the upper side wall of the box opening in the horizontal state, and the lower edge binding plate 20 is used to bind the lower side wall of the box opening in the horizontal state. The two work together to complete the left and right edge binding of the box opening.

[0031] As the cardboard box, which is placed horizontally in the horizontal box conveying mechanism 7, is conveyed along the conveying path, the upper and lower side walls of the box opening will be edged at the corresponding upper and lower edge-sealing mechanisms 5, and the left and right side walls of the box opening will be edged at the corresponding left and right edge-sealing mechanisms 6.

[0032] The box opening edge-sealing device of this paper box can cooperate with the corresponding edge-sealing mechanism to seal the upper and lower edges and the left and right edges respectively during the horizontal paper box body conveying process, forming a pair-to-pair edge-sealing structure. The adjacent positions of the box opening are less likely to interfere with each other, the edge-sealing is relatively smooth, and the edge-sealing operation is relatively more balanced and stable. The upper and lower edges can be processed at the same time, and the left and right edges can also be processed at the same time. The edge-sealing is relatively efficient and can be adapted to complete the edge-sealing of the box opening after the paper box body is formed. It can be used for edge-sealing selection for different paper box production processes.

[0033] Based on the above embodiments, the following optimizations or further explanations can be made.

[0034] For example, the horizontal box conveying mechanism 7 has multiple conveying methods. For instance, an intermittent horizontal box conveyor belt 70 can stop horizontally placed cardboard boxes at the corresponding upper and lower edge-wrapping mechanisms 5 and left and right edge-wrapping mechanisms 6 during conveying for edge-wrapping processing. The intermittent horizontal box conveyor belt 70 has a relatively mature and simple structure, making it easy to configure in this embodiment. The horizontal box conveyor belt 70 (such as a suction conveyor belt) has a straight conveying path, enabling it to convey cardboard boxes along a straight direction. The horizontal box conveying mechanism 7 has a first edge-wrapping station and a second edge-wrapping station. One of the upper and lower edge-wrapping mechanisms 5 and the left and right edge-wrapping mechanisms 6 is located at the first edge-wrapping station, and the other is located at the second edge-wrapping station. The upper and lower edge-wrapping mechanisms 5 are arranged before or after the left and right edge-wrapping mechanisms 6. In the figure, the upper and lower edge-wrapping mechanisms 5 are arranged in front, and the left and right edge-wrapping mechanisms 6 are arranged behind, completing the upper and lower edge-wrapping first, and then completing the left and right edge-wrapping.

[0035] For example, the upper edge-binding component 1 is correspondingly set on the upper side of the lower edge-binding component 2 to form an upper and lower paired edge-binding structure; The upper edge-sealing plate 10 is installed on the first lifting plate 11. The upper edge-sealing plate 10 moves up and down together with the first lifting plate 11. The upper edge-sealing plate 10 is located below the first lifting plate 11. The upper edge-sealing plate 10 moves down with the first lifting plate 11 to fold the face paper down. The upper edge-sealing plate 10 moves back and forth on the first lifting plate 11 to insert the edge, moving the folded face paper area forward towards the box opening and inserting the edge to cover the inner wall of the box opening, thus completing the upper edge sealing. After that, the upper edge-sealing plate 10 moves back and forth, and then rises up with the first lifting plate 11 to wait for the next operation. The lower edge-sealing plate 20 is installed on the second lifting plate 21. The lower edge-sealing plate 20 moves up and down together with the second lifting plate 21. The lower edge-sealing plate 20 is located on the upper side of the second lifting plate 21. The lower edge-sealing plate 20 moves up with the second lifting plate 21 to cooperate with the upward folding of the face paper. The lower edge-sealing plate 20 moves back and forth on the second lifting plate 21 to cooperate with the edge insertion action, moving the folded face paper area forward towards the box opening and inserting the edge to cover the inner wall of the box opening, thus completing the lower edge sealing. After that, the lower edge-sealing plate 20 moves back and then descends with the second lifting plate 21 to wait for the next operation. For example, the lifting actions of the first lifting plate 11 and the second lifting plate 21 can be driven by cylinders or motors, respectively. The first lifting plate 11 and the second lifting plate 21 can be positioned on the vertical guide rod for lifting actions. In addition, the upper edge plate 10 is driven by cylinder 13 or motor (vertically or obliquely) on the first lifting plate 11 to move back and forth to cooperate with the edge insertion action. The lower edge plate 20 is driven by cylinder 23 or motor (vertically or obliquely) on the second lifting plate 21 to move back and forth to cooperate with the edge insertion action. The upper edge plate 10 and the lower edge plate 20 each move forward into the box opening to insert the edge, and move backward to retract from the box opening to reset.

[0036] Further optimization: The first lifting plate 11 includes a first pressing part 12. When the first lifting plate 11 descends, the first pressing part 12 will also descend to press the outer wall of the box opening (i.e., the outer wall of the box opening on the upper side of the box body). This can press the box opening so that the upper edge-sealing plate 10 can smoothly seal the edge, and can even play an auxiliary role in supporting the paper box body to cooperate with the clamping and sealing of the edge.

[0037] For example, the upper edge-sealing plate 10 moves straight forward on the first lifting plate 11 to cooperate with the insertion edge; or, the upper edge-sealing plate 10 moves obliquely outward on the first lifting plate 11 to cooperate with the insertion edge. The oblique insertion edge has a better effect and can exert a force on the inner wall of the box opening (obliquely pressing towards the first pressing part 12), resulting in better edge-sealing quality; even, the first pressing part 12 can press the outer wall of the box opening to cooperate with the outside of the box body to provide additional support, and can cooperate with the oblique insertion edge of the upper edge-sealing plate 10 to clamp and press the edge-sealing.

[0038] Further optimization: the second lifting plate 21 includes a second pressing part 22. When the second lifting plate 21 rises, the second pressing part 22 will also rise to press the outer wall of the box opening (i.e., the outer wall of the box opening on the lower side of the box body). This can press the box opening so that the lower edge-sealing plate 20 can smoothly seal the edge, and can even play an auxiliary role in supporting the paper box body to cooperate with the clamping and sealing of the edge.

[0039] For example, the lower edge-sealing plate 20 moves straight forward on the second lifting plate 21 to cooperate with the insertion edge; or, the lower edge-sealing plate 20 moves diagonally outward on the second lifting plate 21 to cooperate with the insertion edge. The diagonal insertion edge has a better effect and can exert a force pressing against the inner wall of the box opening (diagonally pressing towards the second pressing part 22), resulting in better edge-sealing quality; even, the second pressing part 22 can press against the outer wall of the box opening to cooperate with the outside of the box body to provide additional support, and can cooperate with the diagonal insertion edge of the lower edge-sealing plate 20 to clamp and press the edge-sealing edge firmly.

[0040] Furthermore, the first pressing part 12 and the second pressing part 22 can even cooperate to form a clamping space for the box opening. This allows the first pressing part 12 and the second pressing part 22 to clamp the box opening vertically during edge wrapping, applying pressure to the box opening and holding its upper and lower outer edges. This not only stabilizes the box opening position but also limits its vertical position, resulting in more even edge wrapping. It also ensures stable edge wrapping even when there is no mold support inside the box.

[0041] For example, the left edge-binding component 3 is positioned to the left of the right edge-binding component 4, forming a left-right paired edge-binding structure; The left edge-sealing plate 30 is installed on the first sliding plate 31. The first sliding plate 31 moves left and right, and the left edge-sealing plate 30 moves left and right along with the first sliding plate 31. The left edge-sealing plate 30 is located to the right of the first sliding plate 31. The left edge-sealing plate 30 moves to the right with the first sliding plate 31 and flips the edge to the right, thus folding the face paper to the right. The left edge-sealing plate 30 moves back and forth on the first sliding plate 31 to cooperate with the edge-insertion action, moving the folded face paper area forward towards the box opening and inserting the edge to cover the inner wall of the box opening, thus completing the left edge sealing. After that, the left edge-sealing plate 30 moves back and then moves to the left with the first sliding plate 31 to wait for the next operation. The right edge-sealing plate 40 is installed on the second sliding plate 41. The second sliding plate 41 is set to move left and right, and the right edge-sealing plate 40 moves left and right together with the second sliding plate 41. The right edge-sealing plate 40 is located to the left of the second sliding plate 41. The right edge-sealing plate 40 moves to the left with the second sliding plate 41 and flips the edge to the left, thus folding the face paper to the left. The right edge-sealing plate 40 moves back and forth on the second sliding plate 41 to cooperate with the edge-insertion action, moving the folded face paper area forward towards the box opening and inserting the edge to cover the inner wall of the box opening, thus completing the right edge sealing. After that, the right edge-sealing plate 40 moves back and then moves to the right with the second sliding plate 41 to wait for the next operation. For example, the left and right translation movements of the first translation plate 31 and the second translation plate 41 can be driven by cylinders or motors, respectively. The first translation plate 31 and the second translation plate 41 can be positioned on a horizontal guide rod with a left and right orientation for left and right (translation) movements. In addition, the left side edge plate 30 is driven by cylinder 33 or motors on the first translation plate 31 to move back and forth (vertically or obliquely) to cooperate with the edge insertion movement. The lower side edge plate 20 is driven by cylinder 43 or motors on the second lifting plate 21 to move back and forth (vertically or obliquely) to cooperate with the edge insertion movement. The upper side edge plate 10 and the lower side edge plate 20 each move forward into the box opening to insert the edge, and then move backward to retract from the box opening to reset.

[0042] Further optimization: the first translation plate 31 includes a third pressing part 32. When the first translation plate 31 moves to the right, the third pressing part 32 also moves to the right to press the outer wall of the box opening (i.e., the outer wall of the box opening on the left side of the box body). This has the function of pressing the box opening so that the left edge-sealing plate 30 can smoothly seal the edge, and can even play an auxiliary role in supporting the paper box body to cooperate with the clamping and sealing of the edge.

[0043] For example, the left edge banding plate 30 moves straight forward on the first sliding plate 31 to cooperate with the insertion of the edge; or, the left edge banding plate 30 moves diagonally outward on the first sliding plate 31 to cooperate with the insertion of the edge. The diagonal insertion of the edge is more effective and can exert a force that presses against the inner wall of the box opening (diagonally pressing towards the third pressing part 32), resulting in better edge banding quality; even, the third pressing part 32 can press against the outer wall of the box opening to help press the box body from the outside and provide additional support. This can cooperate with the diagonal insertion of the left edge banding plate 30 to clamp and press the edge together to ensure a tight edge banding.

[0044] Further optimization: the second translation plate 41 includes a fourth pressing part 42. When the second translation plate 41 moves to the left, the fourth pressing part 42 also moves to the left to press the outer wall of the box opening (i.e., the outer wall of the right side of the box opening). This presses down the box opening so that the right side edge-sealing plate 40 can smoothly seal the edge. It can even provide additional support for the paper box body to cooperate with the clamping and sealing of the edge.

[0045] For example, the right edge-sealing plate 40 moves straight forward on the second sliding plate 41 to cooperate with the insertion edge; or, the right edge-sealing plate 40 moves diagonally outward on the second sliding plate 41 to cooperate with the insertion edge. The diagonal insertion edge has a better effect and can exert a force pressing against the inner wall of the box opening (diagonally pressing towards the fourth pressing part 42), resulting in better edge-sealing quality; even, the fourth pressing part 42 can press against the outer wall of the box opening to help press the box body from the outside and provide additional support. It can cooperate with the diagonal insertion edge of the right edge-sealing plate 40 to clamp and press the edge-sealing edge firmly.

[0046] Furthermore, the third pressing part 32 and the fourth pressing part 42 can even cooperate to form a clamping space for the box opening. This allows the third pressing part 32 and the fourth pressing part 42 to work together to clamp the box opening on both sides during edge banding. This combined pressure on the outer edges of the box opening not only stabilizes the box opening but also limits its position on both sides, resulting in more balanced edge banding. It also ensures stable edge banding even when there is no mold support inside the box.

[0047] The fore-and-aft movement of each edging panel is configured on corresponding guide rails, which are set on the inner sides of the corresponding lifting or sliding plates. The guide rails can be slide rails or grooves 14, 24, 34, or 44. Corresponding sliders are configured on the slide rails or grooves for installing the corresponding edging panels. The grooves... In this embodiment, the upper and lower edge-sealing mechanisms 5 and the left and right edge-sealing mechanisms 6 are located beside (on the front side) the conveying path (of the horizontal box conveying mechanism 7). The first edge-sealing station and the second edge-sealing station are also equipped with box clamping and positioning devices 71 to clamp the corresponding box for edge-sealing, and then release the box after edge-sealing is completed. For example, the box clamping and positioning device 71 includes left and right clamping components. The left and right clamping components are used to clamp and position the (horizontal) cardboard box body as it is conveyed from the left and right to the corresponding edge-sealing station, ensuring a more uniform relative position of the box body during edge-sealing and preventing displacement. For example, the left and right clamping components are respectively mounted on a slide that can be adjusted left and right. The slide is equipped with a rotating shaft 75, and the rotating shaft 75 is equipped with a swing arm. The swing arm is driven by a cylinder to swing back and forth, thereby driving the rotating shaft 75 to rotate forward and reverse on the slide. The rotating shaft 75 is equipped with a rod 73 for clamping the cardboard box.

[0048] In addition, the first edge-wrapping station is equipped with a first bottom-pushing box alignment device 721, and the second edge-wrapping station is equipped with a second bottom-pushing box alignment device 722. Each bottom-pushing box alignment device (721, 722) includes a bottom-pushing movable component 72. The bottom-pushing movable component 72 pushes the bottom plate of the horizontal box body towards the box opening, so that the horizontal cardboard box body is more accurately positioned at the corresponding station, ensuring smooth edge wrapping and guaranteeing edge wrapping quality. For example, the bottom-pushing movable component 72 can be driven by a cylinder or motor to move back and forth, pushing the box body towards the box opening. Furthermore, the bottom-pushing movable component 72 is also equipped with a suction nozzle, which has the function of sucking up the cardboard box and pushing it. After the cardboard box is pushed into place, the suction state of the suction nozzle is released. In the diagram, the upper and lower edge-sealing mechanisms 5 are arranged in front, and the left and right edge-sealing mechanisms 6 are behind. The upper and lower edge-sealing is completed first, followed by the left and right edge-sealing. Usually, the second bottom-pushing box body positioning device 722 pushes the box body further forward than the first bottom-pushing box body positioning device 721. The upper and lower edge-sealing mechanisms 5 are closer to the conveying path of the horizontal box body conveying mechanism 7 than the left and right edge-sealing mechanisms 6, resulting in a more reasonable structural layout. In this structure, the left and right edge-sealing mechanisms 6 can also be set in the telescopic box opening limiting baffle 78, which can be equipped with cylinders or motors to cooperate with the telescopic action. The box opening limiting baffle 78 is located between the left edge-sealing assembly 3 and the right edge-sealing assembly 4. When the second bottom-pushing box body positioning device is working, the box opening limiting baffle 78 can cooperate to block and limit the box opening, allowing the paper box body to quickly enter the correct position when pushed by the second bottom-pushing box body positioning device.

[0049] In addition, the horizontal box conveying mechanism 7 also has a labeling station 81 to enable more functions. The labeling station 81 is used to affix labels (such as stickers) to the box body. Furthermore, a box-flipping station 82 can be provided between the labeling station 81 and the second edge-sealing station to flip the horizontal box body up and down, allowing for labeling after the box body is flipped, according to requirements. The labeling station 81 is equipped with a box labeling device, which works in conjunction with the labeling process. For example, a suction nozzle can be used to hold the label and place it on the box body for labeling. For example, the box turning station 82 is equipped with a lifting frame 83 (which can be driven by a cylinder or driven by a motor and a lead screw mechanism). The lifting frame 83 is equipped with a flipping frame 84 (for example, driven by a cylinder to flip 180 degrees and invert). The flipping frame 84 is equipped with left and right clamping plates 85 (including a left plate and a right plate, which are driven by a cylinder or a motor to open and close).

[0050] The horizontal box conveying mechanism 7 also includes a box input end equipped with a box-picking and turning robot 86 for switching the box to a lateral orientation for placement (this is a mature technology, such as CN220720447U, a robot in a strip assembly machine). This robot can be configured to match the direction of the box output from the forming equipment with the conveying path direction of the horizontal box conveying mechanism 7, allowing for flexible layout. The box-picking and turning robot 86 includes box picking and placing components 87 (such as suction nozzles or clamps).
