The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings: like Figure 1-4 As shown, in this embodiment, a top and bottom cover glue spraying box folding machine is provided, including a frame 26, the frame 26 is equipped with a material taking device, a driving motor 1, a feeding device and a forming device, the driving motor 1 is equipped with a commutator, the commutator includes a rotating shaft 6, the rotating shaft 6 is equipped with a transmission assembly, and the rotating shaft 6 controls the linkage of the material taking device, the feeding device and the forming device through the transmission assembly; A discharging assembly 4 is provided below the forming device. The forming device and the taking device are both mounted above the feeding device. A glue dispensing assembly 28 is also provided on one side of the forming device. When the feeding device transports the cardboard 25, the cardboard 25 is open and placed on the guide strip 14. The cardboard 25 will first pass through the glue dispensing assembly 28 and then be sent to the forming device. The glue dispensing assembly 28 will sense that the cardboard 25 moves under it and apply glue.

[0024] In this embodiment, the glue dispensing component 28 is located above the feeding device. The glue dispensing component 28 is arranged between the material taking device and the forming device for dispensing glue during the paper box transportation process. The cardboard 25 is transported to the bottom of the forming device only after the glue is dispensed. The drive motor 1 is connected to the rotating shaft 6 in a transmission manner. The drive motor 1 is the main driving component in the present invention. The drive motor 1 controls the rotation of the rotating shaft 6 to drive the operation of the core device of the whole machine.

[0025] In this embodiment, the transmission assembly includes a first transmission assembly, a second transmission assembly and a third transmission assembly; The forming device includes a punching column 7 slidably mounted on a frame 26, and a rotating shaft 6 controls the punching column 7 to move back and forth in a vertical direction through a first transmission assembly; when the punching column 7 moves up and down, it can control the cardboard 25 to move downward for forming. The specific forming reason is the forming sheet metal group 9 (mentioned below).

[0026] The material taking device includes a flip frame 17 and a suction fixture 20. The rotating shaft 6 controls the flip frame 17 to rotate relative to the frame 26 and controls the suction fixture 20 to rotate relative to the flip frame 17 through the second transmission assembly. The suction fixture 20 is provided with a plurality of suction nozzles, which can generate negative pressure to suck the cardboard 25 out of the storage bin 5. The feeding device includes a sliding plate 12 slidably mounted on a frame 26 , and the rotating shaft 6 controls the sliding plate 12 to reciprocate horizontally relative to the frame 26 through a third transmission assembly.

[0027] In this embodiment, the first transmission assembly includes a driving sprocket fixedly arranged on the rotating shaft 6, a first chain 3, a first transmission shaft 10, a slider crank mechanism 11 and a pair of tensioning sprockets 2, the first transmission shaft 10 is rotatably mounted on the frame 26, a driven sprocket is fixedly arranged at one end of the first transmission shaft 10, the other end of the first transmission shaft 10 is fixedly connected to the first crank block of the slider crank mechanism 11, a pair of tensioning sprockets 2 are rotatably mounted between the driven sprocket and the driving sprocket, and the first chain 3 is meshed with the driven sprocket, the driving sprocket and the pair of tensioning sprockets 2. That is to say, the rotating shaft 6 controls the first transmission shaft 10 to rotate through the first chain 3, the driven sprocket and the driving sprocket, and the rotation of the first transmission shaft 10 can control the first crank block (mentioned below) of the slider crank mechanism 11 to rotate.

[0028] Specifically, the crank slider mechanism 11 includes a first crank block and a connecting rod, which is rotatably connected to one end of the first crank block. The forming device includes a pair of linear guide rails vertically mounted on the frame 26. The punching column 7 is slidably connected to the frame 26 through the linear guide rails. A pressing plate 8 is fixedly arranged at the bottom of the punching column 7. The forming device also includes a forming sheet metal group 9, which is arranged below the pressing plate 8 and above the discharge component 4. The cardboard 25 is transferred between the pressing plate 8 and the forming sheet metal group 9 through the guide strip 14 and the feeding device. When the pressing plate 8 is pressed down, the cardboard 25 will follow the pressing plate 8 and pass through the forming sheet metal group 9 to be formed. After forming, the paper box will fall smoothly onto the discharge component 4 under the action of gravity. The preferred discharge component 4 is a conveyor belt mounted on the frame 26, and the conveyor belt is provided with an independent click to control its own movement. The forming sheet metal group 9 is composed of a forming sheet metal group 9 arranged around the outer peripheral side of the pressing plate 8. The top end of the forming sheet metal is bent and extended outward. The different heights of the forming sheet metal can control the folding order of the long box pages, inner tongue and short box pages of the paper box to achieve the forming purpose.

[0029] In this embodiment, the second transmission assembly includes a crank rocker mechanism 27, which includes a second crank block and a second connecting rod, one end of the second crank block is fixedly connected to the rotating shaft 6, and the other end is rotatably connected to the second connecting rod, one end of the second connecting rod is rotatably connected to one side of the flip frame 17, and the side frame bar rotatably connected to the flip frame 17 and the second connecting rod serves as a rocker of the crank rocker mechanism 27. That is, when the rotating shaft 6 rotates, it will control the flip frame 17 to rotate, and specifically, the flip frame 17 rotates around the positioning shaft 18.

[0030] In this embodiment, the second transmission assembly further includes a positioning shaft 18 and a follower shaft 19, and the two ends of the flip frame 17 are rotatably connected to the positioning shaft 18 and the follower shaft 19, respectively. The positioning shaft 18 is fixedly connected to the frame 26, and the two ends of the positioning shaft 18 are fixedly provided with synchronous fixed wheels 22, respectively, that is, the positions of the synchronous fixed wheels 22 and the positioning shaft 18 are always stationary relative to the frame 26, and the flip frame 17 will flip relative to the positioning shaft 18 and the synchronous fixed wheels 22 when the flip frame 17 flips. In order to further increase the preload force of the synchronous belt, a tensioning wheel 24 is optionally preset on the flip frame 17 for tensioning the synchronous belt. Synchronous follower wheels 23 are fixedly provided at both ends of the follower shaft 19, and the synchronous fixed wheel 22 and the synchronous follower wheel 23 on the same side are meshed with a synchronous belt. The flip frame 17 flips back and forth around the positioning shaft 18, and the synchronous fixed wheel 22 and the synchronous belt convert the flipping amount of the flip frame 17 into the rotation angle of the synchronous follower wheel 23. Specifically, because the synchronous fixed wheel 22 is fixed on the frame 26, when the flip frame 17 swings and deflects around the positioning shaft 18, that is, the synchronous fixed wheel 22 will rotate relative to the flip frame 17, so the synchronous fixed wheel 22 will control the rotation of the follower shaft 19 through the synchronous belt. The suction fixture 20 is fixedly connected to the follower shaft 19, and the suction fixture 20 is rotationally connected to the flip frame 17 through the follower shaft 19. That is to say, in the material picking device, the rotating shaft 6 controls the flipping of the flip frame 17 and the suction fixture 20 at the same time.

[0031] In this embodiment, the feeding device includes a pair of horizontal linear guide rails installed on the frame 26, and the sliding plate 12 is slid on the frame 26 through the horizontal linear guide rails. The sliding plate 12 is arranged between the forming device and the discharge component 4 in terms of vertical height. The feeding device also includes a pair of parallel guide bars 14, and the guide bars 14 are horizontally fixed on the frame 26. The material taking device sucks the cardboard 25 (the paper box before forming) and places it on the guide bar 14. The guide bar 14 is located above the horizontal linear guide rail. A pushing assembly is installed on the sliding plate 12, and the pushing assembly is used to abut the cardboard 25 placed on the guide bar 14 to push the cardboard 25 to the forming device.

[0032] The third transmission assembly includes a second crank rocker mechanism 16, the crank block of the second crank rocker mechanism 16 is fixedly connected to the rotating shaft 6, the rocker of the second crank rocker is rotatably connected to one end of the push rod 15, the other end of the push rod 15 is hinged to the sliding plate 12, and the rocker of the second crank rocker mechanism 16 controls the horizontal movement of the sliding plate 12 by flipping. The rocker of the second crank rocker mechanism 16 will swing and rotate, and when swinging, it will control the push rod 15 to move forward, and the movement of the push rod 15 will control the sliding plate 12 to move forward. The sliding plate 12 is slidably mounted on the frame 26 through a horizontal linear guide rail, so the sliding plate 12 has only the degree of freedom of forward and backward movement in the horizontal direction; and when the push rod 15 moves forward or backward, it will rotate in a corresponding manner with the rocker of the second crank rocker mechanism 16.

[0033] Specifically, the sliding plate 12 includes a seesaw 13 and a push cylinder through a push assembly. The middle of the seesaw 13 is rotatably connected to the frame 26. The bottom end of the seesaw 13 is hinged with the piston rod of the push cylinder. When the cardboard 25 needs to be pushed out, the push cylinder is pushed out, and the top end of the seesaw 13 will be pushed up. After the push is pushed up, the height of the seesaw 13 is higher than the height of the guide bar 14, that is, the top of the seesaw 13 extends above the guide bar 14 so that the cardboard 25 can be moved forward during the forward movement; after the material is delivered, it is reset. When resetting, the piston rod of the push cylinder retracts, and the top of the seesaw 13 flips counterclockwise and flips to the bottom of the guide bar 14 without interfering with the placed cardboard 25. In this embodiment, two push assemblies are preferably provided.

[0034] To further explain, a storage bin 5 is provided on one side of the material taking device, and the storage bin 5 is used to place unformed paperboards 25 .

[0035] In summary, every time the rotating shaft 6 rotates one circle, it will control the first transmission assembly, the second transmission assembly and the third transmission assembly to perform a cycle of actions, including controlling the action of the material taking device to suck materials and place them on the guide strip 14 once and resetting, including controlling the feeding device to feed materials once and resetting, and also including controlling the pressing and resetting of the punching column 7 of the forming device once. Under the control of the rotating shaft 6 and the transmission assembly, the material taking device, the feeding device and the forming device can coordinately complete their respective actions without interfering with each other, and can independently complete the process from forming the paperboard 25 to the paper box and transport it out through the discharging assembly 4.

[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered as within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
