Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a carton folding and packaging device. Background Art

[0002] The packaging carton is a common packaging container, which is widely used in industries such as food, medicine, cosmetics, and clothing due to its advantages of low cost, light weight, and convenient transportation.

[0003] The existing packaging cartons are all provided with creases after leaving the factory. Subsequently, assembly workers are still required to fold the packaging cartons along the creases to form them, so that they can be used for packaging and containing items. However, the speed of manually folding cartons is slow, which will consume high labor costs and time costs. Especially when the volume of the cartons to be folded is small, such as the cartons for packaging paper clips, more production costs are often consumed.

[0004] Currently, there are also devices for automatically folding cartons. However, when the volume of the folded cartons is small, such folding devices are prone to excessively squeezing the cartons during the folding process, which may cause the cartons to deform, and thus the quality of the produced cartons does not meet the standards and cannot meet the production requirements of enterprises. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a carton folding and packaging device.

[0011] Preferably, an upper opening mechanism is provided above the fixed clamp. The upper opening mechanism includes a first upper push rod and a first upper guide plate. The first upper push rod can rotate and push the upper side plate to rotate outward. An inclined downward guide section two is provided on the first upper guide plate, and the guide section two can press the upper side plate towards both sides.

[0012] Preferably, an extension plate one is provided on the first upper guide plate. The extension plate one abuts against the upper side plate downward. A first upper guide rod is provided at the rear side of the extension plate one. An arc section three extending outward is provided at one end of the first upper guide rod, and the arc section three is used to guide the upper end plate to rotate outward.

[0013] Preferably, the second upper push rod can rotate and push the upper side plate to rotate towards the center. An inclined downward guide section three is provided on the second upper guide plate, and the guide section three can press the upper side plate towards the center.

[0014] Preferably, the upper sealing mechanism further includes a second upper guide rod and a folding pressing plate. An extension plate two extending towards the folding pressing plate side is provided on the second upper guide plate. The extension plate two abuts against the upper end plate upward.

The pressing plate is used to press and expand the packaging paper box, and the baffle abuts against the side of the packaging paper box.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. The inclined push block abuts against and pushes the front lower plate to rotate towards the center of the packaging paper box. Then, the lower push rod two and the lower guide plate distributed oppositely cooperate with each other, so that the lower side plates on both sides can rotate towards the center, and the top block is used to press the rear lower plate upwards, so that the insertion plate of the rear lower plate can be inserted into the rear lower plate and the lower side plates to realize the closing of the lower port of the packaging paper box. Subsequently, materials are conveyed into the packaging paper box through the feeding hopper, and then the automatic packaging of the materials is realized by using the packaging paper box. The upper push rod two and the upper guide plate two cooperate with each other, so that the upper side plates on both sides can rotate towards the center, and then the folding pressing plate is used to press downwards to bend the folding edge plate, so that when the lower pressing plate presses down the upper end plate later, the folding edge plate can be pressed down and inserted onto the upper side plate to realize the closing of the upper port of the packaging paper box, and then the folding and packaging operations of the packaging paper box are completed. Compared with the folding and packaging of the existing packaging paper box, the structure of this equipment is simple and exquisitely designed, can meet the use requirements of various packaging paper boxes, improve the folding and packaging efficiency of the packaging paper box while ensuring the packaging quality of the packaging paper box, so as to meet the production needs of enterprises;

[0019] 2. The packaging paper box is transferred by the cooperation of the suction cup, the pressing plate, and the baffle. The flat packaging paper box during transfer is pressed by the pressing plate, so that the packaging paper box can be expanded outwards and clamped on the fixed clamp. Then, the packaging paper box can be folded and processed along with the movement of the fixed clamp. At the same time, through the arrangement of the baffle on the side, the baffle can abut against the side of the expanded packaging paper box to ensure that the packaging paper box will not be deformed due to excessive extrusion, improving the reliability and stability of the transfer of the packaging paper box;

[0020] 3. The lower push rod one rotates to push one side of the lower side plate to rotate outwards. At the same time, during the transfer process of the packaging paper box, the lower side plate on the other side rotates outwards due to the inertia of movement. Then, the two lower side plates will rotate outwards on both sides to avoid interference of the lower side plates with the subsequent folding operations of the rear lower plate and the front lower plate, improving the folding operation efficiency of the packaging paper box and also enhancing the reliability of the folding and packaging of the packaging paper box;

[0021] 4. Through the upper push rod 1 and the upper guide plate 1, the two upper side plates are driven to rotate to both sides, and the upper side plates are pressed downward by the extension plate 1 to ensure that the upper side plates will not rebound. At the same time, the guide rod 1 squeezes the upper end plate, causing the upper end plate to deflect and rotate outward, so as to ensure that the upper port of the packaging carton can open outward, avoiding interference with the materials conveyed inside the packaging carton, and making the packaging operation of the packaging carton smoother and more reliable.

[0022] 5. By arranging the upper guide rod 2 and the limiting plate on both sides of the lower pressing plate, the upper guide rod 2 presses the upper end plate downward to prevent the upper end plate from rebounding. The limiting plate abuts against the limiting folding edge plate, so that the folding edge plate can always maintain a downward trend. The lower pressing plate presses the upper end plate downward, so that the folding edge plate can be inserted downward into the upper side plate of the packaging carton. Through the cooperation of the upper guide rod 2 and the limiting plate, the reliability and efficiency of the insertion and fixation of the folding edge plate are improved.

Detailed implementation manner

[0049] The present utility model will be further described below in conjunction with the accompanying drawings and the detailed implementation manner:

[0050] In the description of this specification, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0051] As Figures 1 to 25 shown, a paper box folding and packaging device includes a frame 1. A number of fixed clamps 11 that move in a cycle are arranged on the frame 1. The moving path direction of the fixed clamps 11 is the front-back direction. Specifically, an annular conveyor belt 12 is arranged on the frame 1. The fixed clamps 11 are installed on the conveyor belt 12. The conveyor belt 12 is used to drive the displacement of the fixed clamps 11. The fixed clamps 11 are used to clamp and fix the packaging paper box 8. The packaging paper box 8 can be displaced synchronously with the fixed clamps 11. A platform 13 is arranged on the frame 1. A stop bar 14 is installed on the platform 13. The stop bar 14 is arranged close to the outside of the fixed clamps 11 to prevent the packaging paper box 8 on the fixed clamps 11 from falling out of the fixed clamps 11 during folding operations and the like.

[0052] The packaging carton 8 includes a peripheral plate 81 with through holes opened vertically. The outer periphery of the peripheral plate 81 abuts against the inner side of the fixed clamp 11. On both sides of the upper end of the peripheral plate 81, two upper side plates 82 are respectively provided. An upper end plate 83 is also provided at the upper end of the peripheral plate 81. A foldable edge plate 831 is provided on the upper end plate 83. On both sides of the lower end of the peripheral plate 81, two lower side plates 84 are respectively provided. A lower front plate 85 and a lower rear plate 86 are oppositely distributed at the lower end of the peripheral plate 81.

[0053] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 10 As shown, a feeding mechanism 2, a lower sealing mechanism 3, an upper opening mechanism 4, a feeding hopper 5, an upper sealing mechanism 6, and a discharging mechanism 7 are arranged in the moving direction of the fixed clamp 11. The feeding mechanism 2 includes a feeding chute 21, a limiting rod 22, a sliding plate 23, a suction cup 24, a rotating member 25, a baffle 26, and a pressing plate 27. A number of flat packaging cartons 8 (reference Figure 14 the state of the packaging carton 8 shown) are placed on the feeding chute 21. The suction cup 24 is used to grasp the packaging carton 8 located on the feeding chute 21 and can reciprocate between the feeding chute 21 and the fixed clamp 11. One end of the suction cup 24 uses negative pressure to suck the peripheral plate 81 of the packaging carton 8 and transfers the packaging carton 8 to the corresponding side of the fixed clamp 11.

[0054] The limiting rod 22 is arranged at one end of the feeding chute 21 close to the fixed clamp 11. By abutting against the packaging carton 8 in the feeding chute 21 through the limiting rod 22, the packaging carton 8 will not fall, and it can be more neatly conveyed in the feeding chute 21.

[0055] The suction cup 24 is installed on the rotating member 25. The rotating member 25 is installed on the sliding plate 23 that can reciprocate. The sliding plate 23 is slidably installed on the slide bar 16 of the platform 13. The sliding plate 23 can slide along the length direction of the slide bar 16 and reciprocate between the feeding chute 21 and the corresponding fixed clamp 11, that is, drive the suction cup 24 to reciprocate between the feeding chute 21 and the corresponding fixed clamp 11.

[0056] The rotating member 25 can drive the suction cup 24 to reciprocally rotate towards the feeding chute 21 or the fixed clamp 11 side. The rotating member 25 can be a rotating cylinder. By the action of the rotating member 25, 180-degree repeated rotation of the suction cup 24 can be realized. When the suction cup 24 grasps the packaging carton 8 in the feeding chute 21, the rotating member 25 drives the suction cup 24 to rotate 180 degrees. At this time, the suction cup 24 rotates towards the corresponding fixed clamp 11. By continuously displacing the suction cup 24, the packaging carton 8 grasped by the suction cup 24 can be transferred to the fixed clamp 11.

[0057] The baffle 26 is disposed opposite to the extrusion plate 27. The baffle 26 and the extrusion plate 27 are distributed on the path of the suction cup 24 for transferring the packaging carton 8. The extrusion plate 27 is used to extrude and expand the packaging carton 8. Refer to Figures 14 to 15 Regarding the state change of the packaging carton 8, by extruding the flat packaging carton 8 in transit with the extrusion plate 26, the packaging carton 8 can be expanded outward and snapped onto the fixed clamp 11. Then, the packaging carton 8 can be processed subsequently as the fixed clamp 11 moves.

[0058] The baffle 26 abuts against the side of the packaging carton 8. By providing the baffle 26 on the side, the baffle 26 can abut against the side of the expanded packaging carton 8 to ensure that the packaging carton 8 will not be deformed due to excessive extrusion, improving the reliability and stability of the transfer of the packaging carton 8.

[0059] Refer to Figure 1 、 Figures 5 to 9 As shown, the lower sealing mechanism 3 includes a first lower push rod 31, a first lower guide rod 32, a push block 33, a second lower push rod 34, a lower guide plate 35, a second lower guide rod 36, a top block 37, a first upper guide rod 38, and a pressing block 39. The first lower push rod 31 and the first lower guide rod 32 are disposed below the fixed clamp 11. The first lower push rod 31 is rotatably mounted on the frame 1 through a first lower rotating rod 311. Thus, the first lower push rod 31 can rotate and push the lower side plate 84 to rotate outward. Specifically, refer to Figure 5 As shown in the direction, the first lower push rod 31 rotates and abuts against the rear lower side plate 84 to rotate backward (the front-rear direction in this embodiment refers to the front-rear direction of the movement of the fixed clamp 11, that is, Figure 5 the left side in is the rear direction).

[0060] During the transfer process of the packaging carton 8, the lower side plate 84 on the other side rotates outward with the inertia of the movement, that is, deflects forward as the fixed clamp 11 moves. Then, the two lower side plates 84 will rotate outward on both sides. Refer to Figures 15 to 16 The state change of the packaging carton 8.

[0061] By arranging the lower side plates 84 to rotate on both sides, it is possible to avoid interference of the lower side plates 84 with the subsequent folding operations of the rear lower plate 86 and the front lower plate 85, improving the folding operation efficiency of the packaging carton 8 and also enhancing the reliability of the folding and packaging of the packaging carton 8.

[0062] The lower guide rod 1-32 is arranged between the push block 33 and the lower push rod 1-31. An arc section 1-321 extending outward is arranged on the lower guide rod 1-32. The arc section 1-321 is used to guide the lower front plate 85 to rotate towards the center. The arc section 1-321 is arranged close to the lower push rod 1-31. By rotating the lower push rod 1-31, the rear lower side plate 84 is pushed to rotate outward. Then, the lower front plate 85 is squeezed towards the center of the packaging carton 8 through the arc section 1-321, and the lower front plate 85 is abutted upward by the lower guide rod 1-32, so that the lower front plate 85 maintains an inclined state of rotating towards the center. Refer to Figures 16 to 17 The state change of the packaging carton 8.

[0063] The push block 33 is arranged near one end of the lower guide rod 1-32 away from the arc section 1-321. A driving member 1-331 is inclinedly installed on the platform 13. The driving member 1-331 can be a cylinder. The output end of the driving member 1-331 is connected to the push block 33 to drive the push block 33 to reciprocate. The push block 33 is used to push the lower front plate 85 of the packaging carton 8 to rotate towards the center, so that the lower front plate 85 rotates towards the lower port of the closed packaging carton 8. And through the inclined guiding arrangement of the guide rod 1-32, the lower front plate 85 is inclinedly positioned, making the rotation operation of the lower front plate 85 more reliable and stable.

[0064] The lower push rod 2-34 and the lower guide plate 35 are arranged on both sides of the push block 33. A lower rotating rod 2-341 is rotatably installed on the frame 1. The lower rotating rod 2-341 is used to drive the lower push rod 2-34 to reciprocally swing and rotate. The lower push rod 2-34 can rotate and push the lower side plate 84 to rotate towards the center. Refer to Figure 6 As shown, the lower push rod 2-34 rotates to push the front lower side plate 84 to rotate towards the center of the packaging carton 8.

[0065] An inclined upward guiding section 1-351 is arranged on the lower guide plate 35. The guiding section 1-351 can press the lower side plate 84 towards the center. The guiding section 1-351 of the lower guide plate 35 and the lower push rod 2-34 cooperate with each other to squeeze the two lower side plates 84 of the packaging carton 8 towards the center, so as to fold and close the lower port of the packaging carton 8 with the lower front plate 85 and the lower side plate 84 in sequence. Refer to Figures 17 to 18 The state change of the packaging carton 8.

[0066] A lower guide rod 2-36 is arranged at the rear side of the lower guide plate 35. An arc section 2-361 extending inward is arranged on the lower guide rod 2-36. The arc section 2-361 is arranged close to the lower guide plate 35. The arc section 2-361 is used to guide the lower rear plate 86 to rotate towards the center, and the lower rear plate 86 is pressed upward by the lower guide rod 2-36, so that the lower rear plate 86 maintains an inclined state of rotating towards the center. Refer to Figures 18 to 20 The state change of the packaging carton 8.

[0067] A second driving member 371 is installed on the platform 13. The second driving member 371 can be a cylinder. The output end of the second driving member 371 is connected to the top block 37 to drive the top block 37 to reciprocate up and down. The top block 37 is arranged staggered with the second lower guide rod 36 to prevent the second lower guide rod 36 from interfering with the movement of the top block 37. The top block 37 can upwardly press against the lower rear plate 86 of the packaging carton 8 and fix the lower rear plate 86, enabling the lower rear plate 86 to rotate towards the lower port of the packaging carton 8. And through the inclined guiding arrangement of the second lower guide rod 36, the lower rear plate 86 is inclinedly positioned, making the rotation operation of the lower rear plate 86 more reliable and accurate.

[0068] Specifically, the top block 37 can upwardly press against the lower rear plate 86 and insert the insertion plate 861 of the lower rear plate 86 between the lower front plate 85 and the lower side plate 84. By first inclinedly positioning the lower rear plate 86, the insertion operation of the insertion plate 861 is made more accurate. And by inserting the insertion plate 861 between the lower front plate 85 and the lower side plate 84 to fix the lower rear plate 86, and through the cooperation of the lower rear plate 86, the lower front plate 85, and the lower side plate 84, the lower port of the packaging carton 8 is closed. Refer to Figures 20 to 22 the state change of the packaging carton 8.

[0069] Refer to Figure 1 、 Figures 5 to 7 As shown in the reference, the upper opening mechanism 4 is arranged above the fixed clamp 11. The upper opening mechanism 4 includes an upper push rod 41 and an upper guide plate 42. An upper rotating rod 411 is rotatably arranged on the frame 1. The upper rotating rod 411 is used to drive the upper push rod 41 to rotate. The upper push rod 41 can rotate and push the upper side plate 82 to rotate outward. Refer to Figure 5 As shown in the reference, the upper push rod 41 rotates to push the rear upper side plate 82 to rotate outward.

[0070] The upper guide plate 42 is provided with a downwardly inclined guiding section 421. The guiding section 421 can press against the upper side plates 82 on both sides. Through the cooperation of the upper push rod 41 and the guiding section 421 of the upper guide plate 42, the two upper side plates 82 are driven to rotate to both sides.

[0071] Furthermore, an extension plate 422 is arranged on the upper guide plate 42. The extension plate 422 extends backward. The extension plate 422 downwardly abuts against the upper side plate 82 to ensure that the two upper side plates 82 do not rebound and press and shape the upper side plates 82. Refer to Figure 16 the state of the packaging carton 8 in

[0072] A first upper guide rod 38 is provided at the rear side of the first extension plate 422. One end of the first upper guide rod 38 is provided with a third arc segment 381 extending outward. The third arc segment 381 is arranged close to the first extension plate 422 side. The third arc segment 381 is used to guide the upper end plate 83 to rotate outward. Refer to Figure 17 the state of the medium packaging carton 8, and the upper end plate 83 is extruded and guided by the first guide rod 38, so that the upper end plate 83 maintains a state of rotating and offsetting outward, so as to ensure that the upper port of the packaging carton 8 can be opened outward.

[0073] Refer to Figure 5 、 Figure 9 As shown, the feeding hopper 5 is arranged on the moving path of the fixed clamp 11. The feeding hopper 5 is provided with materials to be conveyed into the packaging carton 8, such as paper clips and other materials. A quantitative amount of materials is fed into the feeding hopper 5 through equipment such as a vibrating disk, and then the materials are conveyed into the packaging carton 8 through the feeding hopper 5.

[0074] Furthermore, the feeding hopper 5 is arranged near the other end of the first upper guide rod 38.
