Description

Technical Field

[0001] The present invention relates to the field of automatic packaging equipment, and particularly to an automatic writing board packaging machine. Background Art

[0002] Before the finished writing board leaves the factory, it needs to be set with a paper shell. The traditional packaging method is to fold the long side of the paper shell, glue it to form a rectangular column with upper and lower openings. At the same time, a foam cotton protective cover is put on the finished writing board, and then the writing board with the protective cover is put into the paper shell, and then the upper and lower openings of the paper shell are closed. The above operations are all completed manually. After putting on the protective cover, the thickness of the writing board increases. Since the paper box is formed first, in order to ensure the fitting degree between the paper box and the writing board, the thickness of the paper box body after forming is almost the same as that of the writing board. As a result, when manually loading the shell, the protective cover of the writing board is prone to rubbing against the paper shell, causing damage to the protective cover or the paper shell, thus affecting the subsequent sale of the overall packaging of the writing board. Summary of the Invention

[0003] To solve the above problems, the present invention provides an automatic writing board packaging machine, which synchronizes the placement of the writing board and the forming of the paper shell through an automated device to reduce damage to the protective cover and the paper shell during the assembly process.

[0032] Refer to Figure 1, the present invention provides a writing board automatic packaging machine. The packaging machine mainly includes a frame 10 serving as the equipment carrier. A workbench 11 is provided inside the frame 10, and the folding process of the paper box is mainly completed on the workbench 11. A transfer mechanism 20 slidably connected to the top of the frame 10, which is used to transport the paper box unfolding pieces and the writing board to the designated processing positions. A paper box processing mechanism 30 slidably connected to the workbench 11, which is used for folding and forming the paper box unfolding pieces. An adhesive applying mechanism 40 provided above the workbench 11, which is used to apply glue to the paper box unfolding pieces so that the folded paper box can maintain a complete paper box state. A pushing mechanism 50 provided on the workbench 11, which is used to push the paper box processing mechanism 30 to further flow on the workbench 11. The following is an elaboration of the specific processing structure and processing process.

[0033] The packaging machine preliminarily forms the paper box through the paper box processing mechanism 30. The paper box processing mechanism 30 includes a bottom frame 31, a cover support 32, and a forming guide block 35. The bottom frame 31 is in the shape of a rectangular cuboid. The cover support 32 is provided above the long side of the bottom frame 31. The forming guide block 35 is fixed on the workbench 11 and is located on the opposite side of the cover support 32. The cover support 32 is used to fold the upper cover of the paper box unfolding piece when the paper box unfolding piece descends, so that the upper cover of the paper box unfolding piece stands up. The initial forming blocks 33 are slidably connected to the two short sides of the bottom frame 31, and the initial forming blocks 33 are used to stand up the side covers of the paper box unfolding piece. A number of secondary forming columns 34 are slidably connected to the initial forming blocks 33, and the secondary forming columns 34 further fold the top of the side cover of the paper box unfolding piece inward. The forming guide block 35 is used to stand up the other long side of the paper box unfolding piece. The forming guide block 35 is provided with a guiding edge, and the guiding edge is used to guide the standing-up process of the long side. Through the above mechanism, the preliminary forming of the paper box is completed while the paper box unfolding piece descends. It should be noted that before the forming guide block 35 and the secondary forming columns 34 move, the writing board needs to be placed in the paper box through the transfer mechanism 20, and then the side of the paper box is folded inward. At the same time, to improve the processing efficiency of the equipment, multiple groups of the paper box processing mechanism 30 can be set. When one paper box processing mechanism 30 continues with subsequent processing, other paper box processing mechanisms 30 can continue with the preliminary forming of the paper box.

[0034] Specifically, several pushing blocks 331 are provided on the top of the primary forming block 33. The primary forming block 33 and the pushing blocks 331 move synchronously, and their movement is pushed by a cylinder. The cylinder is arranged in the bottom frame 31. Through holes are provided in the pushing blocks 331, and the secondary forming columns 34 are slidably connected in the through holes. Connectors are fixed at the ends of the several secondary forming columns 34, and the connectors are connected to another cylinder. Similarly, the secondary forming columns 34 are pushed by a cylinder. Guide inclined platforms 332 are provided on the inner sides of the pushing blocks 331. The guide inclined platforms 332 are used for guiding during the forming of the carton unfolding pieces. Compacting wheels 341 are rotatably connected to the ends of the secondary forming columns 34. When the combination of the carton and the writing board in the carton processing mechanism 30 moves, the compacting wheels 341 can rotate on the surface of the carton, thus avoiding resistance to the movement of the carton.

[0035] Considering that the position of the lid 32 needs to be adjusted during installation, a rotating shaft 12 is rotatably connected to the workbench 11 of this packaging machine. The lid 32 is fixed to the rotating shaft 12. A connecting head 321 is hinged on the lid 32. A lid 32 adjusting cylinder is connected to the connecting head 321. By controlling the telescopic movement of the lid 32 adjusting cylinder, the rotation of the rotating shaft 12 is controlled, and then the rotation of the lid 32 is driven to achieve the effect of adjusting the position of the lid 32.

[0036] For easy understanding, in this packaging machine, the workbench 11 is divided into a forming workbench 111 and a sealing workbench 112. A chute 113 is provided between the forming workbench 111 and the sealing workbench 112. The bottom frame 31 is slidably connected in the chute 113. Sliders and matching slide rails are provided at the bottom of the chute 113. The slide rails are fixed to the frame 10, and the bottom frame 31 is fixed to the sliders. A vertical plate 13 is provided on the sealing workbench 112. A forming hole 131 is provided at the lower part of the vertical plate 13. A pressing roller 132 is provided behind the forming hole 131. The whole carton preliminarily formed by the carton processing mechanism 30 enters the forming hole 131 under the action of the pushing mechanism 50. The upper cover of the carton in the upright state is pressed down through the forming hole 131, and the pressed upper cover of the carton is further shaped by the pressing roller 132.

[0037] Refer to Figure 1It can be known that there are two sealing workbenches 112, and correspondingly, there are also two groups of carton processing mechanisms 30. A pushing mechanism 50 is provided on the opposite side of the sealing workbench 112. The pushing mechanism 50 includes a bottom plate 51 and a top plate 52. The bottom plate 51 is disposed opposite to the forming hole 131, and the bottom plate 51 is slidably connected to the forming workbench 111. The top plate 52 is slidably connected to the bottom plate 51. A top plate 52 driving cylinder is connected to the top plate 52, and a bottom plate 51 driving cylinder is connected to the bottom plate 51. A plurality of folding fingers 522 are provided at the front end of the top plate 52. During the working process, the top plate 52 is pushed out under the action of the top plate 52 driving cylinder, and the side of the carton is pressed down by the folding fingers 522 provided thereon. Then, the entire carton is pushed by the bottom plate 51 into the forming hole 131 for continuous forming.

[0038] In this equipment, the transfer mechanism 20 includes a plurality of optical rods 21 fixed to the top of the frame 10. Two lifting suction cups 22 are slidably connected to the optical rods 21. The lifting suction cup 22 is composed of a suction cup that can be fixed to the end of the cylinder output shaft of the cylinder. The lifting suction cup 22 is used to suck the carton unfolding piece and the writing board. A synchronizing rod 23 is provided between the two lifting suction cups 22 to ensure the synchronization of the lateral movement of the two lifting suction cups 22. The lifting suction cup 22 is fixed to a bearing plate. A through hole is provided on the bearing plate, and the optical rod 21 passes through the through hole. A pushing cylinder 24 is fixedly connected to any one of the lifting suction cups 22. The pushing cylinder 24 pushes the two lifting suction cups 22 to slide on the optical rod 21. During the production process, for the first time, the carton unfolding piece is placed on the bottom frame 31 through the lifting suction cup 22. During the subsequent grasping process, the two lifting suction cups 22 simultaneously grasp the writing board and the carton unfolding piece respectively, and the writing board is placed in the preliminarily formed carton during the descending process, and this cycle is carried out for the placement of the writing board and the carton unfolding piece.

[0039] The gluing process is indispensable for the forming of the carton. The gluing process of this packaging machine is carried out when the carton processing mechanism 30 moves in the chute 113. Specifically, the gluing mechanism 40 includes a glue gun 41 and a guide plate 42. As Figure 2 shown, the glue gun 41 is fixed above the frame 10, the guide plate 42 is fixed to the vertical plate 13, a gap is provided between the guide plate 42 and the vertical plate 13, the glue outlet of the glue gun 41 faces the end of the guide plate 42, the upper cover in the upright state of the preliminarily formed carton passes through the gap, and at the same time, the glue gun 41 evenly applies glue to the upright upper cover. The upper cover with glue is guided by the forming hole 131 and the pressing roller 132 to be attached to the whole carton, so as to realize the sealing of the carton.

[0040] For the convenience of grasping the writing board and the unfolded piece of the paper box, a first clamping position 14 is provided on the forming workbench 111. The first clamping position 14 is used for placing the writing board. A lifting bottom plate 15 is further provided on the frame 10. A lifting drive mechanism is connected to the lifting bottom plate 15. The lifting drive mechanism includes a vertical frame. Rollers are provided at both ends of the vertical frame. A synchronous belt is sleeved on the rollers. A drive motor is connected to the roller at any one end. The lifting bottom plate 15 is fixed to the synchronous belt. The lifting of the lifting bottom plate 15 is realized by driving the rotation of the synchronous belt by the drive motor. A plurality of upright columns 16 are provided on the periphery of the lifting bottom plate 15. A storage cavity is formed by surrounding the upright columns 16. The lifting bottom plate 15 is located at the bottom of the storage cavity. The unfolded piece of the paper box is placed on the lifting bottom plate 15. The unfolded piece of the paper box is lifted to the lower part of the transfer mechanism 20 by the lifting bottom plate 15.

[0041] In summary, the working process of this packaging machine is as follows. First, the unfolded piece of the paper box is transferred into the bottom frame 31 by one of the lifting suction cups 22. During the downward movement of the unfolded piece of the paper box, it is preliminarily formed by the paper box processing mechanism 30. When the unfolded piece of the paper box is sucked again, the other lifting suction cup 22 sucks the writing board and places it into the preliminarily formed paper box. Then, the slider under the bottom frame 31 transfers the paper box processing mechanism 30 to the front of the sealing workbench 112. At the same time, a glue gun 41 is further provided above the workbench 11. When the paper box processing mechanism 30 moves, the glue gun 41 applies glue to the upper cover of the paper shell. Then, through the forming hole 131 and the pressing roller 132 provided on the sealing workbench 112, the upper cover of the paper box is pressed down to form a complete paper box. Since the writing board is placed in the paper box before the paper box is closed in this packaging machine, the situation of damage caused by stuffing the writing board into the paper box in the traditional installation method is reduced. At the same time, the feeding, processing and forming of the writing board and the paper box in this equipment are all realized by automatic equipment, which improves the degree of automation in the packaging process and thus is conducive to improving production efficiency.
