[0017] Beneficial effects

[0018] This invention provides a high-efficiency cardboard box folding device for cardboard box processing. Compared with the prior art, it has the following advantages:

[0019] 1. This high-efficiency carton folding device for carton processing lays the carton to be folded down on a chain conveyor for transport. The openings on both sides of the carton must be kept horizontal. After the chain conveyor transports the carton to the designated position, the first cylinder is activated to drive the assembly block and pressure rod to move at a certain angle. The pressure rod will press on the top of the laid-down carton, and the locking block will abut against one side of the carton. At this time, the second cylinder is activated to drive the slider to move along the slide bar, which will drive the first cylinder to move to one side. At the same time, the first cylinder continues to run and pushes the moving end outward. Combined with the friction between the carton and the chain conveyor, the pressure rod moves diagonally downward to flatten and fold the carton. When the locking block contacts the bottom of the chain conveyor, it will retract into the pressure rod. When the pressure rod moves upward, the locking block will pop out due to the spring force.

[0020] 2. This high-efficiency carton folding device is used for carton processing. After the chain conveyor continues to transport the flattened and folded carton, it is sent to the pressure roller of the auxiliary compaction component. The servo motor is started to drive the drive pulley to rotate. The drive pulley then drives the driven pulley to rotate through the transmission belt. In this way, the drive pulley and the driven pulley can drive the two pressure rollers to rotate at the same time. The pressure rollers will compact the cartons that pass by to prevent them from springing back. At the same time, the rotating pressure rollers will also cooperate with the chain conveyor to assist in the transportation and movement of the cartons. Attached Figure Description

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 5This application provides a high-efficiency carton folding device for carton processing, including a chain conveyor 1, a folding assembly 2 disposed on the outer side of the chain conveyor 1, and an auxiliary compaction assembly 3 disposed on the outer side of the chain conveyor 1. The folding assembly 2 includes a support rod 21, a mounting plate 22 fixedly connected to the top of the support rod 21, a through groove 27 opened inside the mounting plate 22, a protrusion 23 fixedly connected to the top of the mounting plate 22, a slide rod 24 fixedly connected between two protrusions 23, a slider 25 slidably connected to the outer wall of the slide rod 24, a first cylinder 26 fixedly connected inside the slider 25, an assembly block 29 fixedly connected to the movable end of the first cylinder 26, a pressure rod 210 fixedly connected to one side of the assembly block 29, and a second cylinder 28 fixedly mounted on the top of the mounting plate 22, the movable end of the second cylinder 28 being fixedly connected to one side of the slider 25. A spring 211 is fixedly connected to the inner wall of the pressure rod 210, and a locking block 212 is fixedly connected to the movable end of the spring 211. The locking block 212 is slidably connected to the inner wall of the pressure rod 210.

[0031] In practice: The cardboard box to be folded is laid flat on the chain conveyor 1 for transport. The openings on both sides of the cardboard box must be kept horizontal. After the chain conveyor 1 transports the cardboard box to the designated position, the first cylinder 26 is activated to drive the assembly block 29 and the pressure rod 210 to move at a certain angle. The pressure rod 210 will press on the top of the laid-down cardboard box, and the locking block 212 will abut against one side of the cardboard box. At this time, the second cylinder 28 is activated to drive the slider 25 to move along the slide rod 24, which will drive the first cylinder 26 to move to one side. At the same time, the first cylinder 26 continues to move and pushes outward. Combined with the friction between the cardboard box and the chain conveyor 1, the pressure rod 210 moves diagonally downward to flatten and fold the cardboard box. When the locking block 212 contacts the bottom of the chain conveyor 1, it will retract into the pressure rod 210. When the pressure rod 210 moves upward, the locking block 212 will pop out due to the elastic force of the spring 211. The through groove 27 provides the first cylinder 26 with the space to move.

[0032] Reference Figures 1 to 5 In one aspect of this embodiment, the auxiliary compaction assembly 3 includes guard plates 31, with pressure rollers 32 rotatably connected between the two guard plates 31. One end of each pressure roller 32 is fixedly connected to a driving pulley 33 and a driven pulley 35, respectively. A transmission belt 34 is wound between the driving pulley 33 and the driven pulley 35. The auxiliary compaction assembly 3 also includes a servo motor 36, the output shaft of which is fixedly connected to one side of the driving pulley 33.

[0033] In practice: As the chain conveyor 1 continues to transport, the flattened and folded carton is sent to the pressure roller 32 of the auxiliary compaction component 3. The servo motor 36 is started to drive the drive pulley 33 to rotate. The drive pulley 33 then drives the driven pulley 35 to rotate through the transmission belt 34. Thus, the drive pulley 33 and the driven pulley 35 can drive the two pressure rollers 32 to rotate simultaneously. The pressure rollers 32 will compact the cartons that pass by to prevent them from springing back. At the same time, the rotating pressure rollers 32 will also cooperate with the chain conveyor 1 to assist in the transport and movement of the cartons.

[0034] All electrical devices in this plan are powered by an external power source.

[0035] Working Principle: In the carton folding process, the carton to be folded is first placed on the chain conveyor 1 in a laid-down position for transport. During this process, it is necessary to ensure that the openings on both sides of the carton are horizontal to prepare for the subsequent folding process. After the chain conveyor 1 accurately transports the carton to the designated position, the first cylinder 26 is activated. It drives the assembly block 29 and the pressure rod 210 to move at a specific angle. Under this action, the pressure rod 210 will accurately press on the top of the laid-down carton, while the locking block 212 will firmly abut against one side of the carton, providing stable support and positioning for the initial folding of the carton. Next, the second cylinder 28 is activated, driving the slider 25 to move smoothly along the slide bar 24. Since the slider 25 is connected to the first cylinder 26, this movement will in turn drive the first cylinder 26 to move to one side. At the same time, the first cylinder 26 does not stop operating, and its moving end continues to push outward. Under the coordinated action of this series of actions, combined with the friction generated between the carton and the chain conveyor 1, the pressure bar 210 moves diagonally downwards, gradually flattening and folding the carton. When the locking block 212 contacts the bottom of the chain conveyor 1, it automatically retracts into the pressure bar 210. When the pressure bar 210 moves upwards, the locking block 212 quickly pops out under the force of the spring 211, preparing for the next operation. As the chain conveyor 1 continues to transport, the flattened and folded carton is sent to the pressure roller 32 of the auxiliary compaction component 3. At this time, the servo motor 36 starts, driving the drive pulley 33 to rotate. The drive pulley 33 transmits power to the driven pulley 35 through the transmission belt 34, making the two rotate synchronously. Driven by the drive pulley 33 and the driven pulley 35, the two pressure rollers 32 begin to rotate simultaneously. The rotating pressure rollers 32 compact the passing carton, effectively preventing the carton from springing back and ensuring the stability of the folding effect. At the same time, the rotating pressure roller 32 will work in conjunction with the chain conveyor 1 to assist the carton in continuing to move forward and complete the entire process of folding and compacting the carton.
