Description

Technical Field

[0001] This application relates to the technical field of case openers, and particularly to a fast carton case opener. Background Art

[0002] A case opener, also known as a forming machine, refers to a special device that automatically completes case opening, forming, bottom board folding, and pastes the bottom board tape. It opens the carton folded into cardboard, folds the bottom board of the carton according to a certain procedure, and transports it to the packing machine after sealing with tape. An automatic carton forming machine and an automatic case opener are production line devices for automatically opening large quantities of cartons, automatically folding the lower cover, and automatically sealing the lower bottom tape, and are essential devices for large-scale automated production.

[0003] During the case opening process, it is first necessary to grasp and place it on the conveyor belt through a grasping structure. The conveyor belt drives the carton to pass through the case opening structure, folding structure, and sealing structure in sequence. The case opening structure opens the carton, the folding structure folds the bottom board of the carton, and finally the sealing structure seals the bottom board of the carton.

[0004] Therefore, before sealing the carton, multiple structures such as the grasping structure, conveyor belt, case opening structure, and folding mechanism need to cooperate together to achieve it, which makes the entire process take a longer time. Moreover, if one of the structures has a problem, it will slow down the entire case opening speed, thereby reducing the case opening efficiency of the carton. At the same time, the carton bottom has four bottom boards. Therefore, the folding structure needs to use driving forces in multiple directions to push the four bottom boards to rotate. Therefore, the driving forces in these several directions need to cooperate with each other to achieve it. If there is a problem with the driving force in a certain direction, it will have an adverse impact on the case opening effect, thereby reducing the case opening effect. Summary of the Invention

[0005] In order to improve the case opening efficiency and case opening effect of the carton, this application provides a fast carton case opener.

[0006] A fast carton case opener provided by this application adopts the following technical solutions:

[0007] A fast carton case opener includes a frame body, on which a folding mechanism and a sealing mechanism are arranged. The folding mechanism includes:

[0008] A first folding board and a second folding board. The first folding board is arranged on the frame body and is in a horizontal state. The second folding board is arranged on the upper surface of the first folding board and is inclined upward and located on the side of the first folding board away from the sealing mechanism. The distance between the top end of the second folding board and the sealing mechanism is greater than the distance between the bottom end and the sealing mechanism. The first folding board and the second folding board cooperate to fold two opposite bottom boards of the carton.

[0009] Two guide rods, the two guide rods are arranged on the frame body and are located on the side of the first folding plate close to the sealing mechanism, and the distance between the two ends of the two guide rods close to the sealing mechanism is less than the distance between the two ends far from the sealing mechanism; when the carton moves, the folding of the two bottom plates is realized first, and then the folding of the other two bottom plates is realized through the two guide rods;

[0010] An adsorption seat, the adsorption seat adsorbs and positions two adjacent side walls of the carton that are perpendicular to each other in sequence;

[0011] A manipulator, the manipulator is used to drive the adsorption seat to rotate and move. The adsorption seat first adsorbs and positions one side wall of the carton, and drives the carton to move and rotate under the drive of the manipulator. The carton rotates and opens under the action of gravity, and makes the other side wall of the carton abut against the adsorption seat and is adsorbed and positioned by the adsorption seat; the carton realizes folding and sealing in sequence under the drive of the manipulator;

[0012] When the carton moves above the first folding plate, it is in an inclined state, and the distance between the top end and the sealing mechanism is less than the distance between the bottom end and the sealing mechanism. When the carton moves down and contacts the first folding plate, the folding of the first bottom plate is realized. When the carton moves horizontally away from the sealing mechanism and contacts the second folding plate, the folding of the second bottom plate is realized. The carton moves down and rotates to make the carton in a horizontal state, and makes the two bottom plates abut against the first folding plate to maintain the folded state of the two bottom plates.

[0013] By adopting the above technical solution, the manipulator drives the adsorption seat to rotate and move. The adsorption seat abuts against the stacked cardboard carton for adsorption. The adsorption seat drives the carton to move and rotate, so that the contact point between the adsorption seat and the carton turns to the highest point, so that the carton opens under the action of gravity and abuts against the adsorption seat. Then the adsorption seat adsorbs the other side wall of the carton, so that the carton can be opened under the action of gravity, and the state of the carton after opening can also be adsorbed and positioned, so that the carton can be opened and positioned during the conveying process of the carton.

[0014] The carton moves above the first folding plate. The carton and the bottom plate are in an inclined state, and the two bottom plates are at different heights. The carton moves down to drive the bottom plate to move down, so that the bottom plate at the lower position contacts the first folding plate to realize the folding of the first bottom plate. The carton drives the bottom plate horizontally closer to the second folding plate. During the movement, the first folding plate positions the folded bottom plate, so that the bottom plate at the higher position is folded under the push of the second folding plate, so as to realize the folding of the two bottom plates; then the carton moves down along the second folding plate and approaches the first folding plate and rotates, so that the carton is in a horizontal state. At this time, the folding of the two bottom plates is completed and they abut against the first folding plate for positioning.

[0015] The manipulator drives the carton to move horizontally. The carton moves horizontally and folds the other two bottom plates through two guide rods. The carton moves horizontally to the sealing mechanism for sealing. Then the adsorption seat is unlocked and driven back to its original position by the manipulator to prepare for the next carton opening.

[0016] The manipulator realizes the rotation and movement of the carton during the whole process, enabling the carton to be opened and positioned during the grasping and conveying process. At the same time, one of the two bottom plates is folded through the first folding plate and the second folding plate, and then the other two bottom plates are folded through two guide rods. Therefore, the whole process only requires one driving source of the manipulator, reducing the probability that the opening speed will be slowed down if one of the multiple driving sources has problems during operation. Thus, the opening efficiency and effect are improved, and energy is saved at the same time.

[0017] The inclined carton and the inclined second folding plate enable the two bottom plates to be folded in a predetermined folding direction, making the two bottom plates rotate towards the inside of the carton, improving the stability during the folding process and the opening effect. Moreover, it also makes the two bottom plates closer to the first folding plate and the second folding plate. At the same time, the carton turns to the horizontal during the folding process of the bottom plates, and then the carton directly moves horizontally to the sealing mechanism for sealing, so that the path for the manipulator to drive the carton to move is shorter. Therefore, the opening effect and efficiency are further improved, and energy is saved.

[0018] Optionally, the adsorption seat includes:

[0019] The first adsorption plate and the second adsorption plate, which are connected to each other and perpendicular and are connected to the manipulator;

[0020] The first suction cup and the second suction cup, which are respectively arranged on the first adsorption plate and the second adsorption plate and are respectively used for adsorbing and positioning adjacent side walls of the carton. The first adsorption plate first abuts against the carton and adsorbs and positions the carton through the first suction cup. After the carton is opened, it abuts against the second adsorption plate and is adsorbed and positioned through the second suction cup. When the carton moves above the first folding plate, the second adsorption plate and the second suction cup are located on the side of the carton away from the sealing mechanism.

[0021] By adopting the above technical solution, the first adsorption plate abuts against the carton, and the first suction cup adsorbs the carton. Then the manipulator drives the carton to rotate and move, making the first suction cup turn to the highest position, so that the carton is suspended. The carton rotates and opens under the action of gravity, making the other side wall of the carton abut against the second adsorption plate. Then the second suction cup adsorbs and positions the carton, so that the carton can be opened and the opened carton can be positioned. In this way, the opening of the carton and the positioning of the opened state of the carton can be realized with a simple structure, improving the opening efficiency and effect.

[0022] When the cardboard box is moved above the first folding plate, the second adsorption plate and the second suction cup are located on the side of the cardboard box away from the sealing mechanism. Therefore, the second adsorption plate pushes the cardboard box to fold the next two bottom plates and approach the sealing mechanism, thereby further improving the stability of the cardboard box during movement and the unpacking effect. At the same time, after the first suction cup and the second suction cup release the adsorption of the cardboard box, the first adsorption plate and the second adsorption plate can directly tilt away from the cardboard box without contacting the cardboard box to move the cardboard box, thereby further shortening the movement path of the manipulator, and thus greatly improving the unpacking efficiency.

[0023] Optionally, a pushing assembly is provided on the frame body to push the four top plates of the cardboard box away from each other and facilitate the placement of items into the cardboard box. The adsorption seat horizontally pushes the cardboard box after folding the bottom plate through the sealing mechanism to the pushing assembly, and when the pushing assembly starts to push the four top plates of the cardboard box away from each other, the cardboard box is positioned through the adsorption seat.

[0024] By adopting the above technical solution, the adsorption seat pushes the cardboard box to be sealed through the sealing mechanism and then moves it to the pushing assembly. The pushing assembly starts to push the four top plates of the cardboard box away from each other, thereby reducing the probability of obstruction when placing items in the subsequent process, further improving the unpacking effect, and the adsorption seat realizes the movement of the cardboard box, thereby improving the unpacking efficiency and unpacking effect.

[0025] Optionally, the pushing assembly includes:

[0026] A sliding frame, which is slidably arranged up and down on the frame body;

[0027] A pushing member, which is arranged on the frame body and used to drive the sliding frame to move;

[0028] Four push plates, the four push plates are arranged on the sliding frame and are respectively used to push the four top plates of the cardboard box away from each other. The four push plates are all in an inclined state, and the distance between the bottoms of the opposite two push plates is less than the distance between the tops.

[0029] By adopting the above technical solution, the pushing member starts to drive the sliding frame to move. The movement of the sliding frame drives the four push plates to move downward. The four push plates push the tops of the top plates to move towards the outside of the cardboard box, thereby realizing the separation of the four push plates from each other. And the push plates are in an inclined state, making it easier for the push plates to enter the inside of the cardboard box and push the tops of the top plates to rotate outward, thus improving the unpacking effect and efficiency of the cardboard box.

[0030] Optionally, a first convex portion in an arc shape is provided on the first folding plate. The contact point between the cardboard box and the first folding plate when moving downward is located on the side of the first convex portion away from the sealing mechanism. A connecting portion parallel to the first folding plate is provided at the bottom of the second folding plate. A second convex portion in an arc shape is provided at one end of the connecting portion close to the first convex portion. Both the first convex portion and the second convex portion are used to push the two bottom plates to turn to the inside of the cardboard box.

[0031] By adopting the above technical solution, after the cardboard box is in an inclined state and moves downward, the first bottom plate is folded, the cardboard box approaches the second folding plate horizontally and moves away from the first convex part, so that the second bottom plate is folded, the cardboard box moves downward and rotates, so that the second bottom plate moves downward and abuts against the connecting part, and the second bottom plate contacts the second convex part. The second convex part pushes the second bottom plate to rotate towards the inside of the cardboard box, and after the convex part contacts the first bottom plate, it also pushes the first bottom plate to rotate towards the inside of the cardboard box, thereby reducing the resilience of the two bottom plates, thus reducing the probability of the two bottom plates rotating back, and therefore improving the stability of the two bottom plates and the unpacking effect of the cardboard box.

[0032] Optionally, the height of the two guide rods at the end close to the sealing mechanism is higher than the height at the end close to the first folding plate. An inclined guide plate is arranged on the frame body and between the two guide rods. The guide plate and the guide rods cooperate to fold the two bottom plates.

[0033] By adopting the above technical solution, the position of one end of the two guide rods close to the first folding plate is the lowest, so that when the guide rods first contact the two bottom plates, they are close to the bottom side of the bottom plates, and the pushing point of the bottom plates is far from the rotation point of the bottom plates. According to the lever principle, the pushing force on the bottom plates is increased, making it easy for the bottom plates to rotate. Moreover, as the bottom plates move, the contact points with the guide rods gradually move upward, so that the bottom plates can continue to contact the guide rods after rotation to push the two bottom plates to rotate and fold.

[0034] The guide plate cooperates with the guide rods to rotate and fold the bottom plates, thereby further reducing the probability of not being able to fold due to non-contact with the bottom plates, and further improving the unpacking effect of the cardboard box.

[0035] Optionally, the sealing mechanism includes:

[0036] A first support arm and a second support arm, the first support arm and the second support arm are rotatably arranged on the frame body. The first support arm is located on the side of the second support arm close to the first folding plate. A first support wheel and a second support wheel are respectively rotatably installed at the tops of the first support arm and the second support arm;

[0037] A linkage rod, the two ends of the linkage rod are rotatably arranged on the first support arm and the second support arm, so that the first support arm and the second support arm rotate simultaneously and in opposite directions;

[0038] A restoring member, the restoring member is arranged on the frame body and connected to the second support arm, and the restoring member drives the first support wheel and the second support wheel to rotate to the same horizontal position and above the frame body;

[0039] A conveying assembly, which is arranged on the frame and is used to convey the end of the tape to a first supporting wheel and is located on the side of the first supporting wheel close to the folding plate. The cardboard box is close to the first supporting wheel, and the first supporting wheel presses the tape against and adheres it to the side wall of the cardboard box.

[0040] A cutting assembly, which is arranged on the frame and is used to cut the sealed tape. After the second supporting wheel is separated from the cardboard box, the cut end of the tape is pressed against and adhered to the side wall of the cardboard box.

[0041] By adopting the above technical solutions, the movement of the cardboard box pushes the first supporting wheel to realize the rotation of the first supporting arm and the second supporting arm, and the first supporting wheel presses the tape against and adheres it to the side wall of the cardboard box. Then, the movement of the cardboard box makes the first supporting wheel press against the two bottom plates, so as to seal the bottom plates with the tape. The first supporting wheel presses against the tape for positioning. At the same time, as the tape in contact with the cardboard box increases, the viscosity between the tape and the cardboard box can also position the tape. The conveying assembly outputs the tape, and after the two bottom plates contact the second supporting wheel, they can continue to press against the tape, thereby further improving the sealing effect of the tape on the two bottom plates.

[0042] When the cardboard box is separated from the first supporting wheel, the cutting assembly is activated to cut the tape, so as to make the cut end of the tape located outside the cardboard box. After the lower surface of the cardboard box is separated from the second supporting wheel, the second supporting wheel rotates back under the action of the restoring member, so that the second supporting wheel presses the cut end of the tape against and adheres it to the side wall of the cardboard box, so that the tape is adhered to the opposite side walls of the cardboard box and is used to seal the bottom plates. At the same time, it can be realized without using a driving source, the structure is simple and the operation is stable, thereby improving the opening effect of the cardboard box and saving energy.

[0043] Optionally, the conveying assembly includes:

[0044] A rubber ring, which is rotatably arranged on the frame and is equipped with a tape.

[0045] A mounting plate, which is arranged on the first supporting arm and is used for guiding and conveying the tape.

[0046] An elastic pressing piece, which is arranged on the first supporting arm and presses against the tape to realize positioning of the tape.

[0047] By adopting the above technical solution, the tape on the rubber ring is moved to the mounting plate and the elastic pressing piece, the elastic pressing piece presses the tape against the mounting plate for positioning, and one end of the tape extends to one side of the supporting wheel 1, and at this time the tape extends above the frame, so after the carton approaches the supporting wheel 1, the supporting wheel 1 presses the tape against the side wall of the carton, and then as the carton moves, the tape seals the two bottom plates, and the movement of the tape pulls the rubber ring to rotate for feeding, and after the carton is separated from the supporting wheel 1, the component pair is cut off. The tape is cut, and the elastic pressing piece and the mounting plate cooperate to position the tape. After the carton is separated from the supporting wheel 2, the supporting wheel 2 pushes the cut end of the tape to adhere to the side wall of the carton for positioning. At the same time, the supporting arm 1 and the supporting arm 2 rotate under the action of the tension member, thereby realizing the transportation of the tape and adhering the tape to the opposite side walls of the carton and sealing the bottom plate. At the same time, it can be achieved without using a driving source, with a simple structure and stable operation, thereby improving the unpacking effect of the carton and saving energy.

[0048] Optionally, the cutting component comprises:

[0049] A cutting arm, the cutting arm is rotatably arranged on the frame and is located between the second supporting arm and the first supporting arm and is located close to the side of the first supporting arm;

[0050] A cutting knife, wherein the cutting knife is arranged on the top of the cutting arm;

[0051] A tension piece, which is arranged on the frame and connected to the cutting arm and causes the cutting knife to rotate to the top of the frame under the action of elastic force;

[0052] An upper shifting plate, which is rotatably disposed on the top of the cutting arm and whose rotation direction is parallel to that of the cutting arm;

[0053] A torque piece is provided on the cutting arm and connected with the upper shifting plate. Under the action of elastic force, the torque piece pushes the upper shifting plate to press against the cutting arm for positioning. When the carton contacts the supporting wheel 1, the upper shifting plate and the cutting arm are pushed to rotate in turn. The cutting arm is separated from the carton and drives the cutting knife to rotate to cut the tape. After the upper shifting plate is separated from the carton, the cut end of the tape is rotated and pressed against the side wall of the carton. After the supporting wheel 2 is separated from the carton, the cut end of the tape continues to be re-pressed.

[0054] By adopting the above technical solution, after the carton pushes the support wheel 1 to rotate, it drives the upper dial plate to rotate. Then, the carton drives the cutting arm and the cutting knife to rotate. At this time, the cutting knife is not in contact with the tape. When the carton disengages from the support wheel 1, since the carton abuts against the support wheel 2, the support wheel 1 does not rotate and remains in its original state. After the carton disengages from the cutting arm, the cutting arm and the cutting knife rotate back under the action of the tension member. Since the upper dial plate continues to press against the carton for positioning, when the carton just disengages from the cutting arm, the rotation angle of the cutting arm is still small. After the carton continues to move for a period of time, the rotation angle of the cutting arm increases, driving the cutting knife to cut the tape. At the same time, the rotation of the cutting arm drives the upper dial plate to be squeezed and rotate downward to avoid interference. After the upper dial plate moves out from below the carton, the upper dial plate rotates back under the action of the torsion member, causing the upper dial plate to push and press one end of the cut tape onto the side wall of the carton. After the upper dial plate disengages from the carton and rotates back to its original position under the action of the torsion member, when the support wheel 2 disengages from the carton, the support wheel 2 continues to press against the side wall of the carton to re-press one end of the cut tape, so that the entire tape is adhered to the side wall of the carton, thereby realizing the cutting of the tape and improving the unpacking effect of the carton.

[0055] Optionally, an upper dial rod extending to the side close to the support wheel 1 is provided on the upper dial plate, and the upper dial rod is located outside the support wheel 1 for avoiding interference.

[0056] By adopting the above technical solution, since the end of the cut tape needs to be located below the highest point of the support wheel 1, the cutting knife needs to be as close to the support wheel 1 as possible. However, a certain length of the tape located outside the carton is also required during tape cutting. Therefore, the upper dial rod needs to contact the carton for avoiding interference and not contact the support wheel 1, so that the support wheel 1 can be as close to the cutting knife as possible, making the length of the cut tape appropriate, and at the same time, the length of the tape located outside the carton after tape cutting is suitable, thereby improving the sealing effect of the carton and the unpacking effect of the carton.

[0057] In summary, the present application includes at least one of the following beneficial technical effects:

[0058] 1. The rotation and movement of the carton throughout the process are realized by the manipulator, enabling the carton to be opened and positioned during the grasping and conveying process. At the same time, the folding of two bottom plates is realized through the folding plate 1 and the folding plate 2, and then the folding of the other two bottom plates is realized through the two guide rods. Therefore, the entire process only requires one driving source of the manipulator, reducing the probability that the unpacking speed will be slowed down if one of the multiple driving sources has a problem during operation. Thus, the unpacking efficiency and effect are improved, and at the same time, energy is saved.

[0059] 2. The inclined carton and the inclined folding plate two enable the two bottom plates to be folded in a predetermined folding direction, causing the two bottom plates to rotate towards the inside of the carton, improving the stability during the folding process and enhancing the unpacking effect. Moreover, it also makes the two bottom plates closer to the folding plate one and the folding plate two. Meanwhile, the carton turns to the horizontal during the folding process of the bottom plates, and then the carton is directly horizontally moved to the sealing mechanism for sealing. As a result, the path for the manipulator to drive the carton to move is shorter, thus further improving the unpacking effect and efficiency, and also saving energy.

[0066] The following further elaborates on the present application in conjunction with the accompanying drawings for 1 - 5.

[0067] An embodiment of the present application discloses a rapid carton opening machine.

[0068] Referring to Figure 1 , the rapid carton opening machine includes a frame body 1, on which a folding mechanism 2, a sealing mechanism 4, and a pushing component 7 are arranged. The folding mechanism 2 is used to grab and convey the carton 15 and open the carton 15. At the same time, the folding mechanism 2 is also used to fold the four bottom plates of the carton 15 and move them to the sealing mechanism 4. The sealing mechanism 4 seals the bottom plate of the carton 15; the pushing component 7 is used to push the tops of the four top plates of the carton 15 away from each other, so as to facilitate the subsequent placement of items into the carton 15.

[0069] The frame body 1 includes a base 11, a first mounting portion 12 and a second mounting portion 13 fixedly installed on the upper surface of the base 11. The first mounting portion 12 and the second mounting portion 13 are arranged at intervals along the length direction of the base 11. An installation groove 18 is formed in the second mounting portion 13 along the length direction of the base 11. The sealing mechanism 4 and the pushing component 7 are arranged at intervals along the length direction of the base 11 on the second mounting portion 13. During the movement of the carton 15, it successively passes through the folding mechanism 2, the sealing mechanism 4, and the pushing component 7 to complete the opening of the carton 15.

[0070] Referring to Figure 1 and Figure 2 , the folding mechanism 2 includes a first folding plate 21, a second folding plate 22, and two guide rods 23. The first folding plate 21 is fixedly installed on the upper surface of the first mounting portion 12, and the length direction of the first folding plate 21 is parallel to the length direction of the base 11. The bottom end of the second folding plate 22 is fixedly installed on the upper surface of the first folding plate 21, and the top end is inclined upward and away from the side of the sealing mechanism 4, so that the distance between the top end of the second folding plate 22 and the sealing mechanism 4 is greater than the distance between the bottom end and the sealing mechanism 4. A support plate 29 is fixedly installed on the top side wall of the second folding plate 22. The bottom end of the support plate 29 is vertically downward and fixedly connected to the upper surface of the first folding plate 21. The support plate 29 is used to support and position the second folding plate 22.

[0071] A first protrusion 25 is fixedly installed on the upper surface of the first folding plate 21 near the end of the sealing mechanism 4. The first protrusion 25 is an internally hollow structure formed by bending a plate. A connecting portion 19 is integrally arranged at the bottom of the second folding plate 22 and near the side of the first protrusion 25. The connecting portion 19 abuts against the upper surface of the first folding plate 21 and extends along the length direction of the first folding plate 21. A second protrusion 27 is fixedly installed on the upper surface of the connecting portion 19 near the end of the first protrusion 25, and the second protrusion 27 is an internally hollow structure formed by bending a plate; the widths of the first folding plate 21, the second folding plate 22, and the connecting portion 19 are the same and smaller than the width of the bottom plate of the carton 15.

[0072] The folding plate one 21 realizes the folding of the first bottom plate of the carton 15, and the folding plate two 22 realizes the folding of the second bottom plate of the carton 15; a guide plate one 26 is fixedly installed on the upper surface of the folding plate one 21. The guide plate one 26 is located on the side of the convex part one 25 away from the sealing mechanism 4. The guide plate one 26 is inclined upward along the length direction of the folding plate one 21 and is fixedly connected to the side wall of the convex part one 25. The guide plate one 26 is used for guiding when the bottom plate moves to the convex part one 25. A guide plate two 28 is fixedly installed on the upper surface of the connecting part 19. The guide plate two 28 is located on the side of the convex part two 27 away from the sealing mechanism 4. The guide plate two 28 is inclined upward along the length direction of the folding plate one 21 and is fixedly connected to the side wall of the convex part two 27. The guide plate two 28 is used for guiding when the bottom plate moves onto the convex part two 27.

[0073] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in FIGS. and, two guide rods 23 are fixedly installed on the side wall of the mounting part two 13 close to the folding plate one 21, and the folding plate one 21 is located between the two guide rods 23. The two guide rods 23 are in a shape of an eight, and the distance between the ends close to the sealing mechanism 4 is smaller than the distance between the ends close to the folding plate one 21, and the height of the ends of the two guide rods 23 close to the sealing mechanism 4 is higher than the height of the ends close to the folding plate one 21. Thus, when the bottom plate just contacts the guide rods 23, the contact point is located on the side close to the bottom of the bottom plate, making it easier for the guide rods 23 to push the bottom plate to rotate. At the same time, after the bottom plate rotates, the bottom of the bottom plate will rotate upward. Therefore, as the height of the guide rods gradually increases, the contact point gradually moves upward, so that it can still contact the bottom plate after the bottom plate rotates and continue to push the bottom plate to rotate for folding.

[0074] A guide plate 14 is fixedly installed on the side wall of the mounting part two 13 close to the folding plate one 21 and between the two guide rods 23. The height of the end of the guide plate 14 close to the sealing mechanism 4 is higher than the height of the end close to the folding plate one 21. The guide plate 14 and the two guide rods 23 cooperate with each other to fold the two un-folded bottom plates. At the same time, the highest points of the guide rods 23 and the guide plate 14 are flush with the upper surface of the mounting part two 13. Thus, when the upper bottom plate of the carton 15 moves to the upper surface of the mounting part 13, it will not collide with the side wall of the mounting part two 13, making the movement of the carton 15 more convenient and stable during the movement process.

[0075] Refer to Figure 1 、 Figure 2 and Figure 3, the folding mechanism 2 further includes a suction seat 3 and a manipulator 24. The suction seat 3 is used to successively adsorb and position two adjacent side walls of the carton 15 that are perpendicular to each other. The manipulator 24 is fixedly installed on the ground on one side of the frame 1, and the suction seat 3 is fixedly installed on the manipulator 24. The manipulator 24 drives the carton 15 to rotate and move. Therefore, within the working range of the manipulator 24, the adjustment of the required position and angle of the carton 15 is realized, and the movement and conveying of the carton 15 are realized.

[0076] The suction seat 3 includes a first suction plate 31, a second suction plate 32, a first suction cup 33 and a second suction cup 34. The first suction plate 31 is fixedly installed on the manipulator 24, and one end of the second suction plate 32 is fixedly installed on one end of the first suction plate 31, and the length direction of the second suction plate 32 is perpendicular to the length direction of the first suction plate 31; the first suction cup 33 is fixedly installed on the side wall of the first suction plate 31 close to the second suction plate 32, and a plurality of the first suction cups 33 are arranged at intervals along the length direction of the first suction plate 31; the second suction cup 34 is fixedly installed on the side wall of the second suction plate 32 close to the first suction plate 31, and one or more second suction cups 34 are provided.

[0077] The manipulator 24 then drives the suction seat 3 to approach the carton 15, so that the first suction plate 31 and the first suction cups 33 are pressed against the side wall of the carton 15 stacked into cardboard, and the side wall of the carton 15 abuts against the second suction plate 32 for positioning. The first suction cups 33 adsorb and position the carton 15. The suction seat 3 drives the carton 15 to rotate away from the carton 15 stacked into cardboard, so that the first suction plate 31 turns to the horizontal state and the second suction plate 32 becomes vertical. Therefore, the carton 15 is in the horizontal state and the first suction cups 33 are located on the upper surface of the carton 15, that is, the first suction cups 33 are located at the highest position of the carton 15, so that the carton 15 stacked into cardboard rotates and opens under the action of gravity, so that the carton 15 abuts against the side wall of the second suction plate 32 and the second suction cups 34. The second suction cups 34 adsorb and position the side wall of the carton 15, so as to realize the opening of the carton 15, and the first suction cups 33 and the second suction cups 34 adsorb on two adjacent side walls of the carton 15 for adsorption and positioning.

[0078] The carton 15 is moved above the first folding plate 21 and rotated, so that the second suction plate 32 turns to the side of the carton 15 away from the sealing mechanism 4. At the same time, the carton 15 is in an inclined state, and the horizontal distance between the top end of the carton 15 and the sealing mechanism 4 is less than the horizontal distance between the bottom end and the sealing mechanism 4. At the same time, at this time, the four bottom plates are also in an inclined state and the inclination directions are the same, that is, the bottom of the bottom plate is inclined towards the side close to the first folding plate 21 and the second folding plate 22. Two bottom plates are located directly above the first folding plate 21 and the other two bottom plates are located on both sides of the first folding plate 21; the carton 15 moves downwards, so that the first bottom plate abuts against the first folding plate 21 to realize the folding of the bottom plate, and the contact point between the bottom plate and the first folding plate 21 is located on the first convex part 25 and the guide plate 26 close to the second folding plate 22.

[0079] The carton 15 moves horizontally to drive the second bottom plate to approach and abut against the second folding plate 22, so that the second bottom plate is folded. The carton 15 moves obliquely downward and rotates parallel to the plane of the second folding plate 22, so that the carton 15 turns to a horizontal state. During the movement and rotation of the carton 15, the second bottom plate passes through the second guide plate 28 and the second protrusion 27 in sequence, so that the second bottom plate turns to the inside of the carton 15. At the same time, the first bottom plate passes through the first guide plate 26 and the first protrusion 25 in sequence, so that the first bottom plate also turns to the inside of the carton 15, thereby reducing the resilience of the two bottom plates and reducing the probability of the two bottom plates rebounding.

[0080] The carton 15 moves horizontally close to the sealing mechanism 4, and the first bottom plate abuts against the first protrusion 25 for positioning, while the second bottom plate abuts against the second protrusion 27 for positioning, so as to maintain the folded state of the two bottom plates. The other two bottom plates are in contact with the two guide rods 23. As the carton 15 moves, the two bottom plates approach each other under the action of the guide rods 23. After the second bottom plate separates from the second protrusion 27, it passes through the first folding plate 21 and the first protrusion 25 in sequence. The two bottom plates in contact with the guide rods 23 are in contact with the guide plate 14. The cooperation of the two guide rods 23 and the guide plate 14 causes the two bottom plates to fold. After the two bottom plates separate from the guide plate 14, they abut against the upper surface of the second mounting portion 13 for positioning, and then the carton 15 moves to the sealing mechanism 4 for sealing.

[0081] Refer to Figure 1 and Figure 4 As shown in FIGS. and, the sealing mechanism 4 includes a first support arm 41, a second support arm 42, a linkage rod 43, a restoring member 44, a conveying assembly 5 and a cutting assembly 6. The bottom ends of the first support arm 41 and the second support arm 42 are rotatably mounted on the second mounting portion 13 through a rotating shaft 45. The first support arm 41 and the second support arm 42 are arranged at intervals along the length direction of the base 11, and the first support arm 41 is located on the side of the second support arm 42 close to the first folding plate 21. The rotating shaft 45 is located in the mounting groove 18. The rotating shaft 45 is in a horizontal state and its axis is perpendicular to the length direction of the base 11. The top ends of the first support arm 41 and the second support arm 42 can turn into the mounting groove 18 or above the second mounting portion 13. A first support wheel 411 is rotatably mounted at the top end of the first support arm 41, and a second support wheel 421 is rotatably mounted at the top end of the second support arm 42. The axes of the first support wheel 411 and the second support wheel 421 are parallel to the axis of the rotating shaft 45.

[0082] The two ends of the linkage rod 43 are respectively rotatably connected to the first support arm 41 and the second support arm 42, so that the first support arm 41 and the second support arm 42 rotate simultaneously and in opposite directions; the restoring member 44 is a tension spring. One end of the restoring member 44 is connected to the second mounting portion 13 and the other end is connected to the second support arm 42. In the initial state, the restoring member 44 causes the first support wheel 411 and the second support wheel 421 to be located above the second mounting portion 13, and the highest points of the first support wheel 411 and the second support wheel 421 are flush.

[0083] Reference Figure 1 and Figure 3 Figure 3 , the conveying assembly 5 is arranged on the second mounting part 13 and is used for conveying the adhesive tape 16 to the first supporting wheel 411 and is located on the side of the first supporting wheel 411 close to the first folding plate 21, and the adhesive surface of the adhesive tape 16 is located on the side close to the first folding plate 21; the cutting assembly 6 is arranged on the second mounting part 13 and is used for cutting the adhesive tape 16.

[0084] The carton 15 moves horizontally close to the first supporting wheel 411, so that the first supporting wheel 411 presses and bonds the end of the adhesive tape 16 on the side wall of the carton 15, and pushes the first supporting arm 41 and the second supporting arm 42 to rotate. The first supporting wheel 411 presses on the adhesive tape 16 for positioning. When the carton 15 moves, it will pull the adhesive tape 16 to move. The conveying assembly 5 is used for conveying the adhesive tape 16; the first supporting wheel 411 moves from the side wall of the carton 15 to below the carton 15 and presses on the adhesive tape 16 and the two bottom plates. When the second supporting wheel 421 moves to below the carton 15, it also presses on the adhesive tape 16 and the two bottom plates for positioning, so that the adhesive tape 16 is bonded to the two bottom plates to achieve sealing.

[0085] After the first supporting wheel 411 moves to the carton 15 for a period of time, the cutting assembly 6 is activated to cut the adhesive tape 16, so that there is still the adhesive tape 16 outside the carton 15. When the second supporting wheel 421 moves to the outside of the carton 15, the second supporting wheel 421 presses and bonds the adhesive tape 16 outside the carton 15 to the side wall of the carton 15. Finally, the first supporting wheel 411 and the second supporting wheel 421 rotate back to their original positions under the pulling force of the restoring member 44, so as to realize that the adhesive tape 16 is bonded to the opposite side walls and the two bottom plates of the carton 15, and the bottom of the carton 15 is sealed, so as to realize the opening of the carton 15, and then continue to open the next carton 15.

A mounting rod 55 is rotatably mounted on the second mounting part 13 and below the first supporting arm 41. The axes of the mounting rod 55 and the rotating shaft 45 are parallel.

[0087] The elastic pressing piece 53 is fixedly mounted on the first supporting arm 41, and the elastic pressing piece 53 is located on the side of the mounting plate 52 close to the first folding plate 21. Under the action of elastic force, the elastic pressing piece 53 presses the adhesive tape 16 on the mounting plate 52 for positioning, and the adhesive surface of the adhesive tape 16 is located on the side close to the first folding plate 21.

[0088] In the initial state, the end of the tape 16 is located above the axis of the second mounting part 13 and below the highest point of the first support wheel 411, and the end of the tape 16 is located above the mounting plate 52 and the elastic pressing piece 53. The mounting plate 52 and the elastic pressing piece 53 cooperate to position the tape 16. A guiding roller 54 is rotatably mounted on the side wall of the second mounting part 13. The axis of the guiding roller 54 is parallel to the axis of the rotating shaft 45. The guiding roller 54 is used to guide the tape 16 between the mounting plate 52 and the elastic pressing piece 53, and the guiding roller 54 contacts the surface of the tape 16 on the side away from the sticky side; after the cardboard box 15 approaches the tape 16, the sticky surface of the tape 16 is adhered to the side wall of the cardboard box 15.

[0089] Refer to Figure 1 and Figure 4 As shown in FIGS. and, the cutting assembly 6 includes a cutting arm 61, a cutting knife 62, a tension member 63, an upper dial plate 64 and a torsion member 65. The bottom of the cutting arm 61 is rotatably mounted on the second mounting part 13 and is located in the mounting groove 18. The rotation direction of the cutting arm 61 is parallel to the axis of the rotating shaft 45 and can be rotated into the mounting groove 18 or above the second mounting part 13. The cutting arm 61 is located between the first support arm 41 and the second support arm 42 and is closer to the first support arm 41; a fixing plate 67 is fixedly mounted on the side wall at the top of the cutting arm 61. The cutting knife 62 is fixedly mounted on the lower surface of the fixing plate 67, and the cutting edge extends to the outside of the fixing plate 67 and extends to the side of the fixing plate 67 close to the first support wheel 411; when the cardboard box 15 pushes the cutting arm 61 to rotate, the cutting knife 62 is located below the tape 16 adhered to the bottom plate and does not contact the tape 16.

[0090] The tension member 63 is a tension spring. One end of the tension member 63 is fixedly mounted on the second mounting part 13 and is connected to the cutting arm 61. The tension member 63 is used to maintain the position of the cutting arm 61 and make the cutting knife 62 located above the second mounting part 13.

[0092] Reference Figure 1 and Figure 4 Figure 4 As shown in FIGS.

[0093]

[0093] , the carton 15 pushes the supporting wheel 1-411, causing the supporting arm 1-41 and the supporting arm 2-42 to rotate simultaneously. The side wall of the carton 15 first pushes the upper lever 66 and the upper plate 64 to rotate away from the cutting arm 61. Then, the side wall of the carton 15 pushes the cutting arm 61 to rotate. At this time, the cutting knife 62 is located below the carton 15 and is not in contact with the tape 16. As the carton 15 moves, the two bottom plates are successively pressed against the supporting wheel 1-411, the upper lever 66, the cutting arm 61, and the supporting wheel 2-421, causing the upper plate 64 and the upper lever 66 to be in a horizontal state and rotate from the side of the rotating shaft 68 close to the supporting wheel 1-411 to the side away from the supporting wheel 1-411. At the same time, the upper plate 64 and the upper lever 66 are pressed against the two bottom plates under the torsion of the torsion member 65. Then, the supporting wheel 1-411, the cutting arm 61, the upper lever 66, and the supporting wheel 2-421 are successively separated from the two bottom plates.

[0094] Reference Figure 1 and Figure 5 Figure 5 , the pushing assembly 7 includes a sliding frame 71, a pushing member 72, and four pushing plates 73. A supporting seat 17 extending above the second installation portion 13 is fixedly installed on the side wall of the base 11. The sliding frame 71 is vertically slidably installed on the side wall of the supporting seat 17 and is located above the second installation portion 13. The pushing member 72 is a cylinder or an electric push rod. The pushing member 72 is fixedly installed on the supporting seat 17, and the piston rod is connected to the sliding frame 71 to drive the sliding frame 71 to move vertically.

[0095] Four push plates 73 are fixedly installed on the sliding frame 71 and are arranged in one-to-one correspondence with the four top plates of the carton 15. At the same time, the four push plates 73 are all in an inclined state, and the distance between the bottoms of two adjacent push plates 73 is less than the distance between the tops, and the length of the bottom end of the push plate 73 is less than the length of the top end, so that it is convenient for the bottoms of the four push plates 73 to extend into the carton 15, and the four push plates 73 respectively push the tops of the four top plates of the carton 15 to move away from each other, so that it is convenient for subsequent items to be put into the carton 15, improving the unpacking efficiency of the carton 15; at the same time, during the operation of the pushing assembly 7, the adsorption seat 3 positions the position of the carton 15. After the operation of the pushing assembly 7 is completed, the adsorption seat 3 releases the adsorption and moves away from the carton 15.

[0096] The working principle of the embodiment of the present application is as follows:

[0097] The manipulator 24 drives the adsorption seat 3 to rotate and move, presses the adsorption plate one 31 and the suction cup one 33 against the carton 15 stacked into cardboard, and makes the carton 15 abut against the adsorption plate two 32 for positioning. The suction cup one 33 adsorbs the carton 15 for positioning. After the carton 15 moves and rotates, the suction cup one 33 turns above the carton 15 and the carton 15 is in a horizontal state. After the carton 15 is opened under the action of gravity, it abuts against the adsorption plate two 32. The suction cup two 34 adsorbs the carton 15 for positioning. The carton 15 moves above the folding plate one 21 and is in an inclined state. The carton 15 moves down and abuts against the folding plate one 21 and the first bottom plate is folded. The carton 15 moves horizontally close to the folding plate two 22 and the first bottom plate is folded. The carton 15 moves down obliquely and rotates until the carton 15 turns to a horizontal state. The carton 15 moves horizontally close to the sealing mechanism 4. The two folded bottom plates abut against the convex part two 27, the folding plate one 21 and the convex part one 25 for positioning. The other two bottom plates are folded under the action of the two guide rods 23 and the guide plate 14.

[0098] The carton 15 approaches the support wheel one 411, so that the tape 16 is adhered to the side wall of the carton 15, and the support wheel one 411 presses against the side wall of the carton 15 so that the tape 16 is adhered to the side wall of the carton 15. The carton 15 pushes the support wheel one 411 and drives the support arm one 41 and the support arm two 42 to rotate into the installation groove 18. The support wheel one 411 also moves below the carton 15 and presses against the tape 16 for positioning. The carton 15 moves and pushes the upper shift lever 66 and the upper shift plate 64 to rotate. Then the carton 15 pushes the cutting arm 61 to rotate. Then the carton 15 is separated from the support wheel one 411, the cutting arm 61, the upper shift plate 64 and the upper shift lever 66 in sequence. The cutting arm 61 rotates back under the action of the torsion member 65 to cut the tape 16, and when the upper shift plate 64 rotates back, it pushes the tape 16 to adhere to the side wall of the carton 15. Finally, after the carton 15 is separated from the support wheel two 421, the support wheel two 421 recompresses the tape 16.

[0099] The carton 15 is horizontally moved below the four push plates 73, and the driving member 72 is activated to drive the four push plates 73 to move downward. The four push plates 73 push the tops of the four top plates of the carton 15 away from each other, so as to facilitate the placement of items into the carton 15, thereby realizing the opening of the carton 15; the driving member 72 is activated to drive the four push plates 73 to move above the carton 15, the first suction cup 33 and the second suction cup 34 release the suction effect, and the mechanical arm 24 drives the suction seat 3 to move away to continue the subsequent grasping and conveying of the carton 15. Therefore, the opening and conveying of the carton 15 are realized through the mechanical arm 24, and no additional power source needs to be activated when the four bottom plates are folded, and the structure is simple and stable, thereby improving the opening efficiency and effect of the carton 15, and saving energy at the same time.

[0100] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
