Description

Technical Field

[0001] This invention relates to the technical field of box folding machines, and in particular to a box folding machine with top and bottom lids that uses adhesive spraying. Background Technology

[0002] Fruits and agricultural products are typically packaged in hinged cardboard boxes. These boxes are made by applying glue to cardboard and folding it. Manually applying glue and folding the boxes would require a lot of labor and be inefficient. Therefore, automated equipment is used for processing.

[0003] An existing automatic box folding machine with top and bottom lids, CN212949420U, uses equipment on both sides to fold the boxes and requires a production line to transport the box pieces, which takes up a lot of space. In addition, it does not have a feeding device and cannot automatically supply the box pieces.

[0004] Another type of automatic box folding machine, patent number CN202223118974.9, uses cylinders and many scattered power components, resulting in high overall manufacturing costs. In addition, its feeding components and forming folding devices are controlled by their own drive components. The paper box forming part uses many components and parts, making maintenance inconvenient. It requires an additional folding lug component, making the overall design redundant and increasing the cost of manufacturing the machine.

[0005] Therefore, a box folding machine is needed to solve the above-mentioned technical problems. Summary of the Invention

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0036] like Figure 1-4As shown, this embodiment provides a top and bottom cover glue spraying and folding box machine, including a frame 26. The frame 26 is equipped with a material picking device, a drive motor 1, a feeding device and a forming device. The drive motor 1 is equipped with a commutator, which includes a rotating shaft 6. The rotating shaft 6 is equipped with a transmission assembly. The rotating shaft 6 controls the linkage of the material picking device, the feeding device and the forming device through the transmission assembly.

[0037] A discharge component 4 is provided below the forming device. The forming device and the picking device are both mounted above the feeding device. A dispensing component 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 bar 14. The cardboard 25 will first pass through the dispensing component 28 and then be sent to the forming device. The dispensing component 28 will sense the cardboard 25 moving under it and apply glue.

[0038] In this embodiment, the dispensing assembly 28 is located above the feeding device and is arranged between the picking device and the forming device for applying glue during the paper box transportation process. The cardboard 25 is transported to the bottom of the forming device only after the glue is applied. The drive motor 1 is connected to the rotating shaft 6 for transmission. The drive motor 1 is the main driving component in this 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.

[0039] In this embodiment, the transmission assembly includes a first transmission component, a second transmission component, and a third transmission component;

[0040] The forming device includes a stamping column 7 slidably mounted on a frame 26. The rotating shaft 6 controls the stamping column 7 to reciprocate in the vertical direction via a first transmission component. When the stamping 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).

[0041] The material handling device includes a tilting frame 17 and a suction fixture 20. The rotating shaft 6 controls the rotation of the tilting frame 17 relative to the frame 26 and the rotation of the suction fixture 20 relative to the tilting frame 17 through the second transmission component. The suction fixture 20 is equipped with multiple suction nozzles, which can generate negative pressure to suck up the cardboard 25 from the storage bin 5.

[0042] The feeding device includes a sliding plate 12 that slides on the frame 26, and the rotating shaft 6 controls the horizontal reciprocating movement of the sliding plate 12 relative to the frame 26 through a third transmission component.

[0043] In this embodiment, the first transmission assembly includes a drive sprocket fixedly mounted on the rotating shaft 6, a first chain 3, a first transmission shaft 10, a crank-slider mechanism 11, and a pair of tension sprockets 2. The first transmission shaft 10 is rotatably mounted on the frame 26. A driven sprocket is fixedly mounted at one end of the first transmission shaft 10, and the other end of the first transmission shaft 10 is fixedly connected to the first crank block of the crank-slider mechanism 11. The pair of tension sprockets 2 are rotatably mounted between the driven sprocket and the drive sprocket. The first chain 3 meshes with the driven sprocket, the drive sprocket, and the pair of tension sprockets 2. That is, the rotating shaft 6 controls the rotation of the first transmission shaft 10 through the first chain 3, the driven sprocket, and the drive sprocket. The rotation of the first transmission shaft 10 can control the rotation of the first crank block (mentioned below) of the crank-slider mechanism 11.

[0044] Specifically, the crank-slider mechanism 11 includes a first crank block and a connecting rod. The connecting rod 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 stamping column 7 is slidably connected to the frame 26 through the linear guide rails. A pressure plate 8 is fixedly installed at the bottom of the stamping column 7. The forming device also includes a forming sheet metal assembly 9, which is located below the pressure plate 8 and above the discharge assembly 4. The cardboard 25 is moved between the pressure plate 8 and the forming sheet metal assembly 9 through the guide strip 14 and the feeding device. When the pressure plate 8 is pressed down, the cardboard 25 will follow the pressure plate 8 and pass through the forming sheet metal assembly 9 to be formed. After forming, the cardboard box will fall smoothly onto the discharge assembly 4 under the action of gravity. Preferably, the discharge assembly 4 is a conveyor belt mounted on the frame 26. The conveyor belt is equipped with an independent motor to control its own movement. The forming sheet metal assembly 9 is composed of forming sheet metal assemblies surrounding the outer periphery of the pressure plate 8. The top end of the forming sheet metal is bent outwards. The different heights of the forming sheet metal can control the folding sequence of the long box flaps, inner tongue, and short box flaps of the cardboard box to achieve the forming purpose.

[0045] 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. The side frame strip of the flip frame 17, which is rotatably connected to the second connecting rod, serves as the rocker arm of the crank-rocker mechanism 27. That is, when the rotating shaft 6 rotates, it controls the flip frame 17 to rotate, specifically, the flip frame 17 rotates around the positioning shaft 18.

[0046] In this embodiment, the second transmission assembly further includes a positioning shaft 18 and a follower shaft 19. 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 synchronous pulleys 22 are fixedly mounted at both ends of the positioning shaft 18. That is, the positions of the synchronous pulleys 22 and the positioning shaft 18 relative to the frame 26 remain stationary. The flip frame 17 only flips relative to the positioning shaft 18 and the synchronous pulleys 22 when it flips. To further increase the preload of the synchronous belt, a tensioning pulley 24 can optionally be pre-set on the flip frame 17 for tensioning the synchronous belt. Synchronous follower wheels 23 are fixedly installed at both ends of the follower shaft 19. Synchronous fixed wheels 22 and synchronous follower wheels 23 on the same side are meshed with a synchronous belt. The tilting frame 17 reciprocates around the positioning shaft 18. The synchronous fixed wheels 22 and the synchronous belt convert the tilting amount of the tilting frame 17 into the rotation angle of the synchronous follower wheels 23. Specifically, because the synchronous fixed wheels 22 are fixed to the frame 26, when the tilting frame 17 swings and deflects around the positioning shaft 18, the synchronous fixed wheels 22 rotate relative to the tilting frame 17. Therefore, the synchronous fixed wheels 22 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 rotatably connected to the tilting frame 17 through the follower shaft 19. In other words, in the material handling device, the rotating shaft 6 simultaneously controls the tilting of both the tilting frame 17 and the suction fixture 20.

[0047] In this embodiment, the feeding device includes a pair of horizontal linear guide rails mounted on the frame 26. The sliding plate 12 is slidably mounted on the frame 26 via the horizontal linear guide rails. The sliding plate 12 is arranged vertically between the forming device and the discharge assembly 4. The feeding device also includes a pair of parallel guide bars 14. The guide bars 14 are horizontally fixed on the frame 26. The picking device picks up the cardboard 25 (the cardboard box before forming) and places it on the guide bars 14. The guide bars 14 are located above the horizontal linear guide rails. The sliding plate 12 is equipped with a pushing assembly, which is used to push the cardboard 25 placed on the guide bars 14 to the forming device.

[0048] 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 arm of the second crank-rocker is rotatably connected to one end of the push rod 15, and the other end of the push rod 15 is hinged to the sliding plate 12. The rocker arm of the second crank-rocker mechanism 16 controls the horizontal movement of the sliding plate 12 by flipping. The rocker arm of the second crank-rocker mechanism 16 will swing, and when it swings, it will control the push rod 15 to move forward. 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. Therefore, the degree of freedom of the sliding plate 12 is only the forward and backward movement in the horizontal direction. When the push rod 15 moves forward or backward, it will rotate in accordance with the rocker arm of the second crank-rocker mechanism 16.

[0049] Specifically, the sliding plate 12 is constructed via a push assembly including a rocker plate 13 and a push cylinder. The middle of the rocker plate 13 is rotatably connected to the frame 26, and the bottom end of the rocker plate 13 is hinged to the piston rod of the push cylinder. When the cardboard 25 needs to be pushed out, the push cylinder pushes out, and the top end of the rocker plate 13 is pushed upward. After being pushed upward, the height of the rocker plate 13 is higher than the height of the guide bar 14, meaning that the top of the rocker plate 13 extends above the guide bar 14, allowing the cardboard 25 to be moved forward during the forward movement. After feeding, it resets. During the reset, the piston rod of the push cylinder retracts, and the top of the rocker plate 13 flips counterclockwise to the bottom of the guide bar 14, without interfering with the placed cardboard 25. In this embodiment, two push assemblies are preferably provided.

[0050] To elaborate further, a storage bin 5 is provided on one side of the material handling device, which is used to place unformed cardboard 25.

[0051] In summary, each rotation of the rotating shaft 6 controls the first, second, and third transmission components to perform one cycle of operation. This includes controlling the material-grabbing device to pick up material and place it on the guide bar 14 once, and then resetting; controlling the feeding device to feed material once and then resetting; and controlling the pressing column 7 of the forming device to press down once and then resetting. Under the control of the rotating shaft 6 and the transmission assembly, the material-grabbing device, feeding device, and forming device can work together to complete their respective actions without interfering with each other. The process from cardboard 25 to carton can be completed autonomously and transported out through the discharge component 4.

[0052] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
