[0002] The semi-pallet forming device is a core forming equipment in the packaging machinery field. It is mainly used for automatically folding and shaping packaging cardboard to form a semi-pallet packaging structure to carry materials. In traditional semi-pallet forming devices, the movement of each folding actuator is highly independent and poorly coordinated, resulting in insufficient synchronization of the entire machine's operation. Under high-speed continuous production conditions, problems such as forming deviation and low yield are prone to occur. Traditional equipment has high structural redundancy, complex parts, high assembly and maintenance costs, and poor equipment adaptability and compatibility with operating conditions. It is difficult to meet the multiple requirements of high-speed production stability, low-cost operation, and flexible changeover production.

[0024] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the semi-tray forming apparatus provided in this application includes: 100 racks; The moving component 200 includes a rotating shaft 210, a first moving component 220, and a first folding component 230. The rotating shaft 210 is rotatably mounted on the frame 100. The first moving component 220 is in transmission cooperation with the rotating shaft 210. The first folding component 230 is mounted on the first moving component 220. The first moving component 220 is used to move along the conveying direction of the cardboard. The first folding component 230 can move with the first moving component 220 and is used to fold the front page 001 and / or the back page 002 of the cardboard. The side folding structure 300 is driven by the rotating shaft 210. The rotating shaft 210 can drive the side folding structure 300 to move. The side folding structure 300 includes a second folding member 310, which is disposed on one side of the first moving member 220. The second folding member 310 is used to fold the side leaf 003 of the cardboard.

[0025] Figure 1 and Figure 5 The x-direction shown is the conveying direction. The frame 100 is laid out according to the paperboard conveying direction. The axis of the rotating shaft 210 is arranged parallel to the paperboard conveying plane. The rotating shaft 210 is rotatable. The first moving part 220 and the rotating shaft 210 form a stable transmission cooperation structure. The first folding part 230 is a bending execution component that directly contacts the paperboard. The first folding part 230 is fixedly installed on the outer working surface of the first moving part 220. Along the paperboard conveying direction, the first folding part 230 preferentially contacts the front page 001 of the paperboard.

[0026] It is understood that this application can actively drive the cardboard to move, with the rotating shaft 210 actively rotating to output power, driving the first moving part 220 to produce a displacement matching the cardboard conveying direction, thereby causing the first folding part 230 to actively conform to the forward-moving cardboard and smoothly fold the front page 001; it is also understood that this application can be passively driven to move by the movement of the cardboard, with the cardboard being continuously conveyed forward by other driving components, causing the front page 001 to contact and push the first folding part 230, relying on the pushing force of the cardboard to drive the first moving part 220 to produce a follow-up displacement, at which time the rotating shaft 210 can passively adapt to the rotation and be compatible with the displacement movement of the first moving part 220.

[0027] After the first folding component 230 completes the bending of the front page 001, as the cardboard moves along the conveying direction, the other first folding components 230 fold and shape the rear page 002 of the cardboard.

[0028] The side folding structure 300 is driven by the rotating shaft 210. The side folding structure 300 rotates with the rotation of the rotating shaft 210. The second folding member 310 moves with the rotation of the rotating shaft 210. The second folding member 310 is located on one side of the first moving member 220 and is positioned corresponding to the two side pages 004 of the cardboard along the conveying direction. After the first folding member 230 completes the folding of the front page 001, the second folding member 310 located in the area where the front page 001 is folded completes the folding of the two side pages 003 of the front page 001. After the first folding member 230 completes the folding of the rear page 002 or folds up at least part of the rear page 002, the second folding member 310 located in the area where the rear page 002 is folded completes the folding of the two side pages 003 of the rear page 002.

[0029] The side folding structure 300 of this application is driven by the rotating shaft 210. The second folding component 310 obtains power from the rotating shaft 210, eliminating the need for a separate drive source such as a cylinder or motor for the side folding structure 300. This simplifies the equipment structure and reduces manufacturing costs and control complexity. The second folding component 310 moves with the side folding structure 300, completing the folding of the side sheet 003 while moving in the direction of the cardboard conveyor. Since the side folding structure 300 is continuously driven by the rotating shaft 210, it can adapt to the needs of high-speed continuous production. Under continuous conveying conditions, it can simultaneously achieve multi-area bending and forming of the front sheet 001, the rear sheet 002, and the side sheet 003. The forming process has a high degree of integration, effectively improving the overall forming efficiency and forming consistency.

[0030] Understandably, the frame 100 is equipped with a paper guide 110 to help regulate the paperboard conveying trajectory and ensure that the paperboard enters the forming station smoothly.

[0031] Understandably, the first moving component 220 employs a chain structure with corresponding transmission. A sprocket 240 matching the chain is mounted on the shaft 210, and the chain meshes around the outside of the sprocket 240 to achieve power transmission. Understandably, the first moving component 220 is also equipped with another sprocket, which is rotatably mounted on the frame 100. Furthermore, a telescopic tensioner 250 is mounted on the frame 100 at the corresponding chain loop position. The chain simultaneously wraps around the outside of the tensioner 250. The tensioner 250 has a telescopic adjustable structure, allowing for fine-tuning based on chain wear and assembly clearance requirements. This achieves adaptive adjustment of chain tension, ensuring the chain remains taut throughout the transmission process and maintaining the uniform speed and stability of the first moving component 220.

[0032] In some embodiments, the side-folding structure 300 includes a second moving member 320, which is driven by a rotating shaft 210, and a second folding member 310 is disposed on the second moving member 320. The second moving member 320 is disposed on one side of the first moving member 220, and can circulate under the drive of the rotating shaft 210. As the cardboard moves forward continuously along the conveying path, the second moving member 320 drives the second folding member 310 to continuously adhere to the side sheet 003 area of ​​the cardboard, smoothly completing the bending and forming of the side sheet 003 during the conveying process. It is understood that by adjusting the transmission position and length of the second moving member 320, the movement speed and working area of ​​the second folding member 310 can be adjusted to match the continuous conveying conditions of the cardboard over a long period of time.

[0033] It is understood that the second moving part 320 can be selected from various closed-loop flexible transmission components. In this embodiment, a chain structure is preferably used as the second moving part 320. The reversing section is used to realize the chain cyclic reversal, ensuring that the second moving part 320 can continuously reciprocate in a closed loop, and can stably drive the second folding part 310 to continuously complete the bending operation of the side sheet 003 of the cardboard.

[0034] In some embodiments, the side-folding structure 300 further includes an intermediate motion structure 330, which is disposed between the rotating shaft 210 and the second moving member 320. The input end of the intermediate motion structure 330 is driven by the rotating shaft 210, and the output end of the intermediate motion structure 330 is driven by the second moving member 320. An independent intermediate motion structure 330 is provided between the power transmission paths of the rotating shaft 210 and the second moving member 320. The input end of the intermediate motion structure 330 is driven by the rotating shaft 210, receiving the rotational motion power output by the rotating shaft 210. The output end of the intermediate motion structure 330 is driven by the second moving member 320, stably transmitting the rotational power to the second moving member 320. This achieves a gradual and smooth power transmission from the rotating shaft 210 to the second moving member 320 without changing the overall linkage timing, ensuring a uniform and regular operating rhythm for the second moving member 320. The rotational speed of the second moving member 320 can be adjusted by regulating the transmission speed of the intermediate motion structure 330. Then adjust the folding action of the second folding component 310.

[0035] In some embodiments, the intermediate motion structure 330 includes a driven shaft 331 and a flexible transmission member 332. The driven shaft 331 is rotatably mounted on the frame 100. A first transmission wheel 333 is mounted on the rotating shaft 210, and a second transmission wheel 334 is mounted on the driven shaft 331. The flexible transmission member 332 is sleeved on the first transmission wheel 333 and the second transmission wheel 334. The first transmission wheel 333 and / or the second transmission wheel 334 are detachably mounted on their respective shafts. The second motion member 320 is in a transmission engagement with the driven shaft 331. The first transmission wheel 333 is mounted on the outer side of the rotating shaft 210, and the second transmission wheel 334 is correspondingly mounted on the outer side of the driven shaft 331. The flexible transmission member 332 is closed-loop sleeved on the outer side of the first transmission wheel 333 and the second transmission wheel 334. The first transmission wheel 333 and / or the second transmission wheel 334 adopt a detachable assembly structure, which can be disassembled and replaced according to the actual forming specifications and conveying speed requirements. A third transmission wheel 321 is also provided on the driven shaft 331, and the second moving component 320 is sleeved on the third transmission wheel 321. Another transmission wheel is also provided on the frame 100, and the second moving component 320 is sleeved on this other transmission wheel. The output end of the driven shaft 331 forms a transmission engagement with the third transmission wheel 321 on the second moving component 320, so that power is transmitted step by step through the rotating shaft 210, the flexible transmission component 332, and the driven shaft 331 to drive the second moving component 320 to run stably.

[0036] Understandably, the flexible transmission component 332 preferably adopts a chain structure. The chain is a closed-loop meshing transmission structure, stably sleeved on the outside of the first transmission wheel 333 and the second transmission wheel 334, and power transmission is achieved through meshing transmission. A tension wheel 335 is provided on the frame 100 corresponding to the outside of the flexible transmission component 332. The tension wheel 335 can press against the outer chain segment and can make fine adjustments to the tension compensation according to the chain assembly gap and running wear, so as to ensure the meshing tightness of the chain in real time.

[0037] In some embodiments, the moving component 200 includes two rotating shafts 210 and two first moving parts 220. The two first moving parts 220 are a front page moving part 221 for folding the front page 001 and a rear page moving part 222 for folding the rear page 002, respectively. A front page folding part 231 is provided on the front page moving part 221, and a rear page folding part 232 is provided on the rear page moving part 222. A front page folding part 231 and a rear page folding part 232 are arranged in a group. The semi-carrying forming device also includes at least one driving structure, which is used to drive the rotating shaft 210 connected thereto to rotate. The driving structure is used to adjust the relative movement speed between the front page moving part 221 and the rear page moving part 222 to adjust the relative distance between the front page folding part 231 and the rear page folding part 232 in the same group. A single front page folding part 231 and a single rear page folding part 232 are paired and matched along the conveying direction. A single group of folding parts works together to complete the forming operation of the front page 001 and the rear page 002 of a single piece of cardboard. The drive structure allows independent adjustment of the operating state of the corresponding rotating shaft 210, enabling adjustment of the relative movement speed between the front page moving part 221 and the rear page moving part 222. This, in turn, dynamically adjusts the relative spacing between the front page folding part 231 and the rear page folding part 232 in the same group, adapting to different cardboard length specifications. The relative spacing between the folding parts can be flexibly adjusted through speed matching, accommodating the forming needs of various cardboard length specifications. The equipment has a wide range of adaptability and is highly convenient to debug.

[0038] In the specific assembly layout, with the input cardboard position as the front and the output cardboard position as the rear, one rotating shaft 210 serves as the front power shaft, independently driving the front page moving component 221 to circulate. At the same time, the shaft structure of this rotating shaft 210 supports the front position of the rear page moving component 222 through the setting of a sprocket 240, ensuring the coaxiality of the rear page moving component 222 assembly and the smoothness of operation. The other rotating shaft 210 serves as the rear power shaft, independently driving the rear page moving component 222 to circulate. At the same time, another sprocket 240 is set on the shaft of this rotating shaft 210 to support the rear end limiting structure of the front page moving component 221. This realizes a layout in which the front page moving component 221 and the rear page moving component 222 support each other and drive independently, improving the overall coaxiality of the two sets of motion components and simplifying the structure.

[0039] In some embodiments, the semi-tray forming apparatus further includes a side guide plate structure 400 disposed on the frame 100. The side guide plate structure 400 is disposed on one side of the first moving member 220 and is used to extend along the conveying direction. At least a portion of the side guide plate structure 400 is used to hold the side sheet 003 of the cardboard at a preset folding angle. After the side sheet 003 of the cardboard is bent by the second folding member 310, it continues to move forward with the cardboard. The bent side sheet 003 can slide smoothly against the inner surface of the side guide plate structure 400. Through the lateral limiting constraint of the side guide plate structure 400, the side sheet 003 is stably maintained at the preset folding angle posture, and the shaping and holding are completed during continuous conveying.

[0040] In some embodiments, the side guide plate structure 400 includes a guide structure 410. One end of the guide structure 410 is connected to the end of the side guide plate structure 400 used for receiving the paperboard. The guide structure 410 retracts towards the first moving member 220, and the other end of the guide structure 410 extends away from the first moving member 220 and in a direction opposite to the conveying direction. The guide structure 410 is used for pre-guiding the side sheet 003. The guide structure 410 has a sloping structure, with one end close to the side of the input paperboard. This end is farther away from the first moving member 220 than the other end. The side sheet 003 can first contact the guide structure 410, and through the sloping guiding effect of the guide structure 410, it completes automatic alignment, correction, and pre-positioning, and then smoothly transitions into the shaping area of ​​the side guide plate structure 400. It is understood that the guide structure 410 is provided with a waist-shaped hole, which, in conjunction with a bolt, can achieve adjustment in a direction perpendicular to the conveying direction.

[0041] The side guide plate structure 400 also includes a side guide plate 420, which is positioned on the side of the guide structure 410 that contacts the cardboard. The side guide plate 420 first contacts the front page 001 of the cardboard and performs a pre-fold, preparing for the front page 001 of the cardboard to contact the guide structure 410 for folding. The folding of the side leaf 003 of the completed second folding piece 310 occurs before the side guide plate 420 completes its pre-fold.

[0042] In some embodiments, the second folding member 310 is used to push the side sheet 003 of the rear page along the conveying direction. The working range of the second folding member 310 is set between the end of the first moving member 220 and the input end of the side guide plate structure 400. The working object of the second folding member 310 is the side sheet 003 corresponding to the rear page 002 of the cardboard. During the movement of the cardboard along the conveying direction, the front page 001 of the cardboard enters the forming station first. The side sheet 003 corresponding to the front page 001 can be pre-bent by the guide structure at the front end of the side guide plate structure 400 and smoothly introduced into the side guide plate structure 400 for posture shaping, completing the forward folding positioning. The forming direction of the side sheet 003 corresponding to the rear page 002 of the cardboard is opposite to the folding direction of the side sheet 003 of the front page 001. Its bending direction is to fit the side of the material to be carried inside the half tray, and the bending direction is opposite to the front folding direction. Therefore, this solution independently limits the bending process of the side sheet 003 of the rear page 002 to a dedicated area downstream of the guide structure and at the feeding front of the side wing guide plate structure 400. This allows the side sheet 003 of the rear page 002 to be bent independently in the reverse direction after the side sheet 003 of the front page 001 has been fully shaped, effectively avoiding interference between the front and rear side sheet forming, preventing the side sheet 003 of the rear page 002 from being mistakenly bent due to the folding trend of the front page, and improving the forming qualification rate.

[0043] In some embodiments, the semi-tray forming apparatus further includes a side guide rod 500 disposed on the frame 100. The side guide rod 500 is used to fold the side page 004 of the cardboard. The side guide rod 500 has a receiving end and an output end. The receiving end is perpendicular to the conveying direction and away from the first moving member 220, and the output end is perpendicular to the conveying direction and close to the first moving member 220. The output end also extends along the direction of folding the side page 004 and along the conveying direction. The input end of the side guide rod 500 is set to be parallel to the conveying plane of the cardboard, and the output end extends along the folding and gathering direction of the side page 004 and the conveying direction of the cardboard. As the cardboard continues to move along the conveying path, the side page 004 gradually and gently folds inward along the gradual trajectory of the side guide rod 500 to complete the final closing and shaping.

[0044] In some embodiments, the semi-tray forming device includes two sets of moving components 200 and two sets of side folding structures 300. The two sets of moving components 200 are respectively disposed on opposite sides of the frame 100, and each set of moving components 200 is correspondingly provided with a set of side folding structures 300. This application adopts a symmetrical structural layout on the left and right opposite sides of the frame 100 along the conveying direction. The moving components 200 and side folding structures 300 on the left and right sides of the frame 100 operate synchronously and in conjunction. During the continuous conveying of the cardboard, the side sheet 003 and side sheet 004 structures on the left and right sides of the cardboard are symmetrically folded and formed simultaneously.

[0045] In some embodiments, a glue gun 700 is provided on the frame 100 near the input cardboard corresponding to the input end of the side guide rod 500, for spraying glue onto the side page 004 and / or the side sheet 003 before folding the side page 004, so that the side page 004 is bonded to the side sheet 003 after folding.

[0046] With the cardboard conveying plane as the horizontal reference plane, several sets of ball bearing structures 620 are installed in the hollow area between the two symmetrically arranged moving components 200 of the frame 100. These ball bearing structures 620 are evenly distributed in an array below the bottom surface of the cardboard conveyor. The ball bearing structures 620 can roll freely, with their top surfaces slightly convex above the support plane of the frame 100. They can support the middle section of the cardboard throughout the high-speed continuous conveying process, preventing the middle section from being suspended, collapsing, deforming, or sagging. Simultaneously, they convert the sliding friction of the cardboard into rolling friction, reducing conveying resistance.

[0047] In some other embodiments, vertical side plate structures are fixedly installed on the left and right sides of the frame 100, and multiple parallel cross braces 610 are horizontally arranged between the two side plates to form a lateral support frame for the entire machine. Two sets of moving components 200 are respectively fixedly connected to the cross braces 610 via independent assembly brackets, achieving stable hoisting and positioning installation based on the overall rigidity of the cross braces 610. Furthermore, both ends of the cross brace 610 are rotatably connected to the two side plates via hinge structures, and one end of the cross brace 610 is driven by an independent spacing drive structure 600. The cross brace 610 has two sections of threaded structures with opposite directions of rotation, and the assembly brackets on both sides used to connect the moving components 200 are correspondingly provided with matching threaded hole structures. By controlling the rotation of the cross brace 610 through the forward and reverse rotation of the spacing drive structure 600, the two side brackets can be driven to synchronously translate in opposite directions along the cross brace 610, adjusting the symmetrical spacing between the two sets of moving components 200.

[0048] In some other embodiments, the side folding structure 300 employs a gear-driven reversing structure to achieve reverse folding operations. Specifically, it includes a first gear and a second gear fixedly mounted on the rotating shaft 210. The second gear meshes with the first gear to form a stable gear transmission connection. The second folding component 310 is fixedly installed on the end face of the first gear. During the rotation of the rotating shaft 210, the first gear is driven to rotate in the opposite direction through gear meshing, thereby driving the second folding component 310 to perform a reverse circular motion. This allows for folding of the side sheet 003 corresponding to the front page 001 of the cardboard during the cardboard conveying process, adapting to different folding sequence requirements. It is understood that an odd number of first gears can be set for multi-stage meshing transmission according to the actual forming conditions, which can flexibly adjust the rotation direction, speed, and starting position of the second folding component 310 to adapt to the folding requirements of the side sheet 003 of the front page 001 of cardboard with different thicknesses and specifications.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
