DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] A carton folding device, such as Figure 1-Figure 5 As shown, it includes a support 1, and a fixed pressure plate assembly 2 and a folding pressure plate assembly 3 are provided below the support 1, and the folding pressure plate assembly 3 is provided on the right side of the folding pressure plate assembly; the folding pressure plate assembly 3 includes a rotating rod 31, and the rotating rod 31 is rotatably provided on the support 1 through a hydraulic rod 32, and a telescopic pressure plate assembly 33 is provided at the bottom of the rotating rod 31.

[0025] Specifically, the support 1 is the foundation of the entire device and is used to fix and support other components. The fixed pressure plate assembly 2 is used to perform preliminary pressure plate fixation on the left side of the carton to ensure that the carton maintains the correct position during the folding process. The folding pressure plate assembly 3 is located on the right side of the fixed pressure plate assembly 2 and is responsible for folding and pressing the folding part of the carton to complete the sealing process. The design of the telescopic pressure plate assembly 33 enables the device to adapt to cartons of different sizes, improving the versatility of the device. The rotating rod 31 is rotatably provided on the support 1 through the hydraulic rod 32, so that the folding pressure plate assembly 3 can be adjusted in angle according to the height and folding requirements of the carton, increasing the flexibility of the device. By controlling the rotating rod 31 through the hydraulic rod 32, the automation of the folding process can be achieved, manual operations can be reduced, and production efficiency can be improved.

[0026] In another specific embodiment, one end of the hydraulic rod 32 is hinged to the fixed platen assembly 2 or the support 1, and the other end of the hydraulic rod 32 is hinged to the rotating rod 31. When a folding operation is required, the hydraulic system is activated, and the hydraulic rod 32 begins to move. Because one end of the hydraulic rod 32 is fixed and the other end is hinged to the rotating rod 31, the extension and retraction of the hydraulic rod 32 is converted into the rotation of the rotating rod 31.

[0027] In another specific embodiment, the telescopic pressure plate assembly 33 includes a fixed pressure plate 331 fixedly connected to the rotating rod 31. The fixed pressure plate 331 is provided with a waist-shaped hole, and a movable pressure plate is connected to the waist-shaped hole, which can be adjusted along the waist-shaped hole. The movable pressure plate is connected to the waist-shaped hole of the fixed pressure plate 331 via bolts, pins, or other components, allowing the movable pressure plate to be adjusted within the waist-shaped hole. When the telescopic pressure plate assembly 33 needs to be adjusted to accommodate cartons of different thicknesses, the operator can release the movable pressure plate's fixing mechanism and then move the movable pressure plate along the waist-shaped hole as needed. When the movable pressure plate reaches the desired position, it is re-secured to stabilize it in its new position. In this way, the contact area of ​​the telescopic pressure plate assembly 33 can be adjusted according to the specific size of the carton. By adjusting the movable pressure plate within the waist-shaped hole, the telescopic pressure plate assembly 33 can accommodate cartons of different sizes and thicknesses, thereby improving the versatility of the folding device.

[0028] In another specific embodiment, the middle portion of the fixed platen 331 is connected to the rotating rod 31, and waist-shaped holes extending in the left and right directions are provided on the left and / or right sides of the fixed platen 331. These waist-shaped holes allow the movable platen to move left and right along the fixed platen 331 to accommodate cartons of different sizes or shapes, thereby adjusting the position of the platen to achieve folding.

[0029] As another specific embodiment, the waist-shaped hole on the left side of the fixed pressure plate 331 is connected to a first movable pressure plate 332. The left end of the first movable pressure plate 332 is provided with a round rod extending in the front-to-back direction. When the carton enters the folding device, the fixed pressure plate 331 and the first movable pressure plate 332 work together to compress and fold the edges of the carton. The curved surface of the round rod contacts the carton, providing uniform pressure and helping to form neat creases along the edges. This curved surface design helps minimize damage to the carton and improve the aesthetics of the packaging.

[0030] In another specific embodiment, a second movable platen 333 is connected to the waist-shaped hole on the right side of the fixed platen 331. The right section of the second movable platen 333 is tilted upward. When the carton is folded, a bend edge forms on its edge. The tilted right section of the second movable platen 333 ensures that the bend edge is not stressed during the folding process, thereby preventing damage to the carton structure.

[0031] As another specific embodiment, when the folding platen assembly 3 is rotated downward to the target position, the retractable platen assembly 33 is positioned below the fixed platen assembly 2. Specifically, the width of the fixed platen assembly 2 is greater than the width of a single cover sheet, and the height of the fixed platen assembly 2 is greater than the folded height of the carton. After folding the left and right cover sheets, the fixed platen assembly 2 can maintain both cover sheets in a horizontal position. During folding of the folding platen assembly 3, the carton's flexibility allows the right cover sheet to be inserted between the upper and lower gaps between the carton body and the fixed platen assembly 2.

[0032] As another specific embodiment, the lower right portion of the fixed platen assembly 2 is curved. When the folding platen assembly 3 rotates downward to fold the right cover, the curved portion helps the cover slip more easily into the gap between the carton body and the fixed platen assembly 2. This curved design reduces linear pressure on the carton cover, preventing tearing or damage to the carton edge during the sealing process. The curved edge is relatively soft, better adapting to the flexibility of the carton.

[0033] The carton folding device provided in this embodiment works as follows:

[0034] The carton moves from right to left and enters beneath the fixed platen assembly 2. The left cover of the carton now contacts the right side of the fixed platen assembly 2, causing it to fold to the right. As the hydraulic rod 32 retracts and extends, the rotating rod 31 pivots downward about its hinge point with the support 1 or the fixed platen assembly 2. The left round rod of the retractable platen assembly 33 contacts the right cover, forcing it to insert into the upper and lower gaps between the carton and the fixed platen assembly 2, folding the left and right covers.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention extends to any new features or any new combinations disclosed in this specification, and any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that detailed technical features not disclosed in this embodiment, such as specific structures and connection methods, can be obtained by those skilled in the art from the prior art, and the present disclosed embodiment does not specifically limit them.
