Description

Technical Field

[0001] This application relates to the technical field of cardboard box processing, and in particular to a high-efficiency cardboard box folding device for cardboard box processing. Background Technology

[0002] Against the backdrop of the rapid development of modern logistics and packaging industries, cardboard boxes, as the most widely used packaging material, directly impact enterprise costs and market competitiveness through their production efficiency. According to data from the China Packaging Federation, my country's annual cardboard box production exceeded 50 million tons in 2023. However, traditional manual folding methods still account for over 60% of the production process in small and medium-sized packaging enterprises.

[0003] Currently, cardboard box folding operations mainly rely on manual labor. Workers must sequentially complete processes such as cardboard creasing, alignment, and tape application. Taking a common 0201 type cardboard box folding device as an example, a skilled worker can only complete 80-100 folded boxes per hour. During peak e-commerce promotions or holiday order surges (with daily orders exceeding 10,000 pieces), the low efficiency of manual folding becomes particularly pronounced. Data from a small-to-medium-sized logistics company shows that manual folding extends peak order delivery times by 40%, and the error rate due to human fatigue reaches as high as 12%, severely impacting packaging quality.

[0004] Furthermore, the high cost of manual folding is becoming increasingly prominent. With labor costs rising year by year, manual folding accounts for 35% to 45% of the total packaging cost, significantly compressing profit margins. Simultaneously, uneven glue application and insufficient bonding strength during tape bonding increase the rate of carton breakage during transportation, further raising after-sales costs. Therefore, to address these issues, this application provides a high-efficiency carton folding device for carton processing. Utility Model Content

[0005] To address the aforementioned problems, this application provides a high-efficiency carton folding device for carton processing.

[0006] This application provides a high-efficiency carton folding device for carton processing, including a guide rail for carton transportation, a folding mechanism above the guide rail, the folding mechanism including two main push plates fixed in position and two side push plates moving in the horizontal direction, and a pushing mechanism below the main push plates and the side push plates, wherein the cylinder telescopic transmission push rod in the pushing mechanism rotates in the range of 0-90°.

[0007] The pushing mechanism below the side push plate moves first, followed by the pushing mechanism below the main push plate. When the pushing mechanism below the main push plate moves to the 1 / 4 position, the pushing mechanism below the side push plate resets.

[0008] By setting a fixed main push plate and a side push plate that moves in a straight line, the side push plate can open up the flat cardboard box. The pushing mechanism located below the main push plate and the side push plate operates separately to perform separate operations on the bottom of the cardboard box, thereby completing the folding operation of the cardboard box.

[0009] Preferably, the pushing mechanism further includes a support rod welded to the outer wall of the main push plate and the side push plate, a cylinder rotatably connected to the end of the support rod, a connecting rod rotatably connected to the bottom of the main push plate and the side push plate, the top end of the connecting rod being rotatably connected to the output end of the cylinder, and the bottom end of the connecting rod being fixedly connected to the push rod.

[0010] Preferably, a linear module is bolted to the outer wall of the main push plate, and the movable block of the linear module is fixedly connected to the side push plate.

[0011] Preferably, a telescopic cylinder is provided below the guide rail.

[0012] Preferably, a pressure rail is provided above the folding mechanism.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] By setting a fixed main push plate and a side push plate that moves in a straight line, the side push plate can open up the flat cardboard box. The pushing mechanism located below the main push plate and the side push plate operates separately to perform separate operations on the bottom of the cardboard box, thereby completing the folding operation of the cardboard box.

[0019] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.

[0020] Example 1:

[0021] A high-efficiency cardboard box folding device for cardboard box processing, as described in the reference. Figure 1 - Figure 3 A high-efficiency carton folding device for carton processing includes a guide rail 1 for carton transportation, a folding mechanism is provided above the guide rail 1, the folding mechanism includes two main push plates 4 fixed in position and two side push plates 5 that move in the horizontal direction, and a pushing mechanism 7 is provided below the main push plates 4 and the side push plates 5, wherein the cylinder 72 in the pushing mechanism 7 extends and retracts the transmission push rod 73 to rotate within the range of 0-90°.

[0022] The pushing mechanism 7 below the side push plate 5 moves first, followed by the pushing mechanism 7 below the main push plate 4. When the pushing mechanism 7 below the main push plate 4 moves to the 1 / 4 position, the pushing mechanism 7 below the side push plate 5 resets.

[0023] By setting a fixed main push plate 4 and a side push plate 5 that moves in a straight line, the side push plate 5 can open up the flat cardboard box. The pushing mechanism 7 located below the main push plate 4 and the side push plate 5 operates separately to perform separate operations on the bottom of the cardboard box, thereby completing the folding operation of the cardboard box.

[0024] The pushing mechanism 7 also includes a support rod 71 welded to the outer wall of the main push plate 4 and the side push plate 5. A cylinder 72 is rotatably connected to the end of the support rod 71. A connecting rod 74 is also rotatably connected to the bottom of the main push plate 4 and the side push plate 5. The top end of the connecting rod 74 is rotatably connected to the output end of the cylinder 72. The bottom end of the connecting rod 74 is fixedly connected to the push rod 73. The connecting rod 74 has an inverted L-shaped structure. Its corner position is rotatably connected to the middle section of the bottom of the main push plate 4 and the side push plate 5. The length of the support rod 71 is greater than the length of the top end of the connecting rod 74. The top end of the support rod 71 and the connecting rod 74 are connected by the cylinder 72. When the cylinder 72 extends, it pushes the connecting rod 74 to rotate around its corner position toward the side of the carton, thereby pushing the carton to fold. When the cylinder 72 retracts, it resets the connecting rod 73. The initial position of the push rod 73 is directly below the main push plate 4 and the side push plate 5.

[0025] The linear module 6 is bolted to the outer wall of the main push plate 4. The movable block of the linear module 6 is fixedly connected to the side push plate 5. The linear module 6 pushes the side push plate 5 to slide along its setting direction. When the side push plate 5 contacts the two sides of the folded carton, such as Figure 1 As shown, the side will be pushed inward, thereby opening the carton. Finally, each side of the carton is fitted with the main push plate 4 and the side push plate 5 respectively. At this time, the pushing mechanism 7 can be started to operate and the carton can be folded.

[0026] A telescopic cylinder 2 is installed below the guide rail 1. The telescopic cylinder 2 can be a hydraulic cylinder or a pneumatic cylinder 72. When the telescopic cylinder 2 extends, the carton is in a folded state. When the telescopic cylinder 2 retracts, it is in a feeding and unloading state. After the folded carton is placed on the guide rail 1, the telescopic cylinder 2 extends to send the carton into the pushing mechanism 7 for folding. After folding, the telescopic cylinder 2 retracts to put the carton down and convey it to the subsequent tape sealing mechanism.

[0027] A pressure rail 3 is installed above the folding mechanism. The pressure rail 3 limits the top of the carton, thereby ensuring that the bottom of the carton is folded smoothly.

[0028] The foregoing description, with reference to preferred embodiments, illustrates an exemplary embodiment of the efficient carton folding device for carton processing provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
