Description

Technical Field

[0001] This invention relates to the technical field of automated equipment for packaging and storing electronic products, particularly for protecting SSD solid-state drives during storage and transportation, and especially to a fully automated equipment for folding and forming paper trays. Background Technology

[0002] As modern electronic products become increasingly sophisticated and integrated—for example, SSDs integrate more and more electronic components within the same size, achieving a significant increase in capacity—increased protection is required during their storage, transportation, and stacking.

[0003] In the design and production of various packaging boxes, to protect the contents and prevent damage from vibration, an inner tray is usually designed to correspond to the shape and structure of the box and its contents. These inner trays are typically made of paper. In actual design and production, inner trays have various structures. For ease of storage and transportation, they are initially generally flat, with creases stamped or sections cut to separate them. When folding and assembly are needed, they are simply folded according to the creases.

[0004] For example, Chinese patent document CN219838753U discloses a product feeding device inside a carton, including a carton conveyor line, a carton opener at the inlet of the carton conveyor line, and an inner tray placement device and a product placement device arranged sequentially along the conveying direction of the carton conveyor line; the inner tray placement device includes an inner tray support frame straddling the top of the carton conveyor line, an inner tray lifting and feeding device at the inner tray feeding end of the inner tray support frame, and a three-axis inner tray gripping device that can move linearly between the inner tray feeding end and the inner tray unloading end is provided on the top of the inner tray support frame corresponding to the lifting end of the inner tray lifting and feeding device.

[0005] For example, Chinese patent document CN213864001U discloses an inner tray edging loading and unloading mechanism, including a bracket, a frame, a transmission device, and an edging machine body. The bracket is fixedly connected to the four corners of the frame, the transmission device is set on the inner frame of the frame, the edging machine body is set on the frame, the frame is provided with a feeding device, the feeding device is provided with a plurality of inner trays, the feeding device is set above the transmission device, and the transmission device includes a rotating roller and a conveyor belt.

[0006] The aforementioned patented solutions are all related equipment for improving the inner packaging trays of products, but their performance does not meet the requirements, especially in the process of folding and forming paper inner trays, where they are not applicable.

[0007] Currently, the production of outer packaging boxes and inner cardboard trays for electronic products used in daily life, especially the folding of the inner trays, is relatively complex. Ordinary mechanical mechanisms are not suitable for automated folding, so manual operation is usually used. This method is inefficient, has high labor costs, and folding the inner trays manually can easily make them dirty and wrinkled, resulting in inconsistent and non-standard product quality. This leads to low production efficiency, high costs, and difficulty in completing production tasks in a timely manner when there are urgent orders, putting the company in a very passive position.

[0008] Although the inner tray of the purchased cardboard has been pre-cut so that it needs to be folded into the shape of an inner tray, the inner tray is only partially cut off but is still on the same plane as the cardboard body. The partially cut inner tray needs to be pressed down and bent to form the shape of the inner tray, so that it can support and accommodate the SSD storage product.

[0009] Currently, the processing method used is still manual folding. Manual folding (4 sizes) takes an average of 28 seconds per piece, requiring 8 people to fold simultaneously to meet the normal production flow of a packaging line. This results in excessively high production costs, and the prolonged repetitive folding motion can easily cause muscle fatigue and strain for workers. To reduce production costs, improve efficiency, and alleviate worker workload, our company has developed this patented technical solution. Summary of the Invention

[0010] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0011] This invention provides a fully automated equipment for folding and forming paper trays, including a frame and a feeding assembly, a transferring assembly, a folding assembly, and a discharging assembly mounted on the frame. The frame has a worktable fixed to it. The feeding assembly is installed at the feeding end of the worktable and is used to convey the paperboard to be processed to the loading station. The transferring assembly and the folding assembly are respectively installed between the feeding end and the discharging end of the worktable.

The folding assembly is used to fold the paperboard to be processed to form a preset tray folding shape. The discharging assembly is installed at the discharging end of the worktable and is used to convey the folded paperboard out of the equipment. The folding assembly (300) is provided with a forming mechanism (310), which is provided with a pressing bracket (311), a pressing cylinder (312), a pressing bearing (313), and a pressing cutter head (320). The pressing bracket (311) is fixed to the worktable (11). The pressing cylinder (312) and the pressing bearing (313) are respectively installed on the pressing bracket (311).

The upper support cylinder (338) is fixed to the forming carrier (330), and the upper support block (337) is driven to the piston rod of the upper support cylinder (338).

[0012] As a further aspect of the present invention: the feeding assembly is provided with a cardboard hopper and a feeding mechanism. The cardboard hopper is used to stack and store a certain number of cardboard sheets to be processed. The feeding mechanism is provided with a feeding suction cup, a feeding cylinder and a feeding bearing. The feeding suction cup is movably connected to the worktable through the feeding bearing. The feeding cylinder is installed on the worktable and its piston rod is driven to the feeding suction cup, so that the feeding suction cup, driven by the feeding cylinder, picks up the cardboard sheets to be processed from the cardboard hopper and moves them to the feeding station.

[0013] As a further aspect of the present invention: the feeding mechanism is further provided with a shifting push plate, a shifting motor and a shifting screw. The shifting motor and the shifting screw are respectively installed on the worktable. The nut of the shifting screw is fixedly connected to the shifting push plate, and its screw is connected to the output shaft of the shifting motor, thereby causing the shifting motor to operate and drive the shifting push plate to move laterally a certain distance through the shifting screw, thereby pushing the cardboard to be processed and moving it to the preset position of the feeding station.

[0015] As a further embodiment of the present invention: the forming mechanism is further provided with a forming carrier and a bending pallet. The forming carrier is fixedly connected to the worktable, and the bending pallet is installed on the forming carrier and is provided with a bending bevel that matches the folding blade, so that the inner support part of the cardboard is folded between the bending bevel and the folding blade under the folding operation of the folding blade to form a folded shape; the forming mechanism is further provided with an upper support pressure block and an upper support cylinder. The upper support cylinder is fixedly connected to the forming carrier, and the upper support pressure block is drivenly connected to the piston rod of the upper support cylinder.

[0016] As a further embodiment of the present invention: the folding assembly is further provided with a folding mechanism, which is used to fold the four sides of the cardboard to form a preset folding shape; the folding mechanism is provided with a folding bracket, a folding cylinder, a folding bearing, a folding pressure plate, a folding stop block, and a folding bending plate; the folding bracket is fixedly connected to the worktable; the folding cylinder and the folding bearing are respectively fixedly connected to the folding bracket; the folding pressure plate is movably connected to the folding bracket through the folding bearing and forms a transmission connection with the piston rod of the folding cylinder; the folding stop block is elastically connected to the folding pressure plate; and the folding bending plate is fixedly connected to the folding pressure plate.

[0017] As a further embodiment of the present invention: the folding assembly is further provided with a folding carrier, a folding support block, a pressing cylinder, and a pressing stop block. The folding carrier, the folding support block, and the pressing cylinder are respectively installed on the worktable. The folding support block is used to abut the lower part of the cardboard. The pressing stop block is driven to the piston rod of the pressing cylinder, so that the pressing cylinder operates and drives the pressing stop block to perform a reinforced folding operation on the four sides of the bent cardboard, so that the four sides of the cardboard form a preset folded shape.

[0018] As a further aspect of the present invention: the material transfer assembly is provided with a first material transfer mechanism and a second material transfer mechanism. The first material transfer mechanism is used to pick up the paperboard to be processed from the feeding station and move it to the forming station.

[0019] As a further embodiment of the present invention: the material transfer assembly includes a material transfer slide rail, a material transfer slider, a material transfer cylinder, a material transfer suction cup, a synchronous belt, a material transfer pulley, and a material transfer motor. The material transfer slide rail and the material transfer motor are respectively fixed to the worktable. The material transfer pulley is rotatably connected to the worktable. One end of the synchronous belt is sleeved on the material transfer pulley, and the other end is drivenly connected to the output shaft of the material transfer motor. The material transfer slider is fixed to the synchronous belt and cooperates with the material transfer slide rail to form a sliding connection. The material transfer cylinder is fixed to the material transfer slider, and the material transfer suction cup is fixed to the piston rod of the material transfer cylinder.

[0020] As a further embodiment of the present invention: the discharge assembly is provided with a transverse slide rail, a transverse slider, a transverse cylinder, a discharge suction cup, and a discharge cylinder.

The transverse slider is drivenly connected to the piston rod of the transverse cylinder and cooperates with the transverse slide rail to form a sliding connection. The discharge cylinder is fixed to the transverse slider, and the discharge suction cup is fixed to the piston rod of the discharge cylinder.

[0021] Compared with the prior art, the beneficial effects of the present invention are: 1. The technical solution of this invention is mainly applied to the forming and processing of cardboard inner trays in the packaging boxes of SSD solid-state drives. By using an automatic control system, the feeding component, the transferring component, the folding component, and the discharging component are automatically controlled. This enables the upper and lower forming mechanisms and folding mechanisms of the folding component, the corresponding transferring manipulators of the transferring component, the automatic feeding device of the feeding component, and the automatic discharging device of the discharging component to be automatically controlled and operated. This achieves automatic feeding, forming, processing, and discharging without manual operation, optimizes the labor intensity of employees, improves production efficiency, and meets the packaging requirements of SSD solid-state drives.

[0022] 2. The feeding mechanism also incorporates a shifting pusher, a shifting motor, and a shifting lead screw to adjust the placement position of the cardboard, allowing it to be pushed to the corresponding preset position. This ensures that the subsequent picking up and placing of the cardboard meets the requirements of the carrier. This improves the positioning accuracy of the cardboard in subsequent operations, reduces subsequent cardboard adjustment steps, optimizes the production process, and increases production efficiency.

[0023] 3. The forming mechanism of the folding component also presses, folds, and squeezes the inner tray of the cardboard to form the inner tray shape of the cardboard, thereby supporting and packaging the SSD solid-state drive product placed inside, and providing shock protection for the product.

[0024] 4. The folding mechanism of the folding component also bends the four sides of the cardboard, forming corresponding folds. The cardboard inner tray can be placed inside the outer packaging box using the four sides, thus packaging the product.

[0025] Therefore, with the above improvements, the present invention can provide a fully automated equipment for folding and forming paper trays, which can automatically produce paper trays, thereby reducing production costs, improving production efficiency, reducing the workload of workers, and improving the production quality of paper trays to meet the packaging requirements of SSD solid-state drive production lines.

Detailed Implementation

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 14In this embodiment of the invention, a fully automated equipment for folding and forming paper trays includes a frame 10, and a feeding assembly 20, a transferring assembly 40, a folding assembly 300, and a discharging assembly 50 installed on the frame 10. The frame 10 has a worktable 11 fixed to it. The feeding assembly 20 is installed at the feeding end of the worktable 11 and is used to convey the paperboard 60 to be processed to the loading station 12. The transferring assembly 40 and the folding assembly 300 are respectively installed between the feeding end and the discharging end of the worktable 11. The transferring assembly 40 is used to pick up the paperboard 60 to be processed and move it to different stations for corresponding processing. The folding assembly 300 is used to fold the paperboard 60 to form a preset inner tray folding shape. The discharging assembly 50 is installed at the discharging end of the worktable 11 and is used to convey the folded paperboard 60 out of the equipment.

[0032] Specifically, to achieve fully automated folding and forming of the cardboard 60 inner tray, corresponding components need to be set up for coordinated operation. These components can be installed inside the frame 10 for easy management. Furthermore, the frame 10 is connected to the electrical and pneumatic components 16 to provide the necessary high-pressure airflow, ensuring the normal operation of all components within the frame 10.

[0033] Secondly, this invention can integrate four different types of folding components 300 onto a single automated device. During production, selective processing can be performed as needed, with the robotic arm of the material transfer component 40 controlled by an existing automated program for separate operations. For example, the corresponding cardboard type 60 can be selected in the automated program, which can then automatically activate the corresponding folding component 300 to fold the cardboard 60, forming the corresponding cardboard 60 inner tray shape.

[0034] like Figure 2 As shown, the folding assembly 300 has a first folding part 301, a second folding part 302, a third folding part 303, and a fourth folding part 304 sequentially installed on the worktable 11, thereby performing preset folding operations on the cardboard 60 to be processed with different folding requirements. Based on the four types of cardboard 60 inner tray shapes currently required by the company, four folding assemblies 300 can be directly installed inside the automated equipment to form the first folding part 301, the second folding part 302, the third folding part 303, and the fourth folding part 304 respectively. This allows one automated equipment to meet the folding processing production of four types of cardboard 60 inner trays. Furthermore, if the company upgrades or adds products in the future, the folding assemblies 300 can be replaced according to the cardboard 60 inner trays required for existing products, thereby extending the service life of the automated equipment and meeting the automated folding processing needs of more types of cardboard 60 inner trays.

[0035] In addition, the present invention also provides a method for folding and forming a paper tray, which realizes the entire process from feeding the cardboard 60 to folding and forming through automated control, thereby achieving full automation of the production of the cardboard 60 tray. Step one: The feeding assembly 20 ensures that the cardboard 60 to be processed is correctly placed at the loading station 12; Step two: The first transferring mechanism 41 of the transferring assembly 40 moves the cardboard 60 from the loading station 12 to the forming station 13 and places it on the forming carrier 330; Step three: The forming mechanism 310 of the folding assembly 300 folds and forms the cardboard 60, so that the tray portion 63 of the cardboard 60 is folded to form the tray shape; Step four: The second transferring mechanism of the transferring assembly 40 then... 42. The folded cardboard 60 is moved from the forming station 13 to the folding station 14 and placed on the folding carrier 350. Step 5: The folding mechanism 340 performs folding processing on the folded cardboard 60, so that the four sides 64 of the cardboard 60 are folded to form a preset shape. Step 6: The unloading component 50 moves the folded cardboard 60 from the folding station 14 to the unloading station 15, so that the folded cardboard 60 is unloaded, thereby completing the entire paper tray folding and forming process.

[0036] like Figure 3 and Figure 4 As shown, preferably, the feeding assembly 20 is provided with a cardboard hopper 21 and a feeding mechanism 22. The cardboard hopper 21 is used to stack and store a certain number of cardboard sheets 60 to be processed. The feeding mechanism 22 is provided with a feeding suction cup 23, a feeding cylinder 24 and a feeding bearing 25. The feeding suction cup 23 is movably connected to the worktable 11 through the feeding bearing 25. The feeding cylinder 24 is installed on the worktable 11 and its piston rod is driven to the feeding suction cup 23, so that the feeding suction cup 23, driven by the feeding cylinder 24, picks up the cardboard sheets 60 to be processed from the cardboard hopper 21 and moves them to the feeding station 12.

[0037] Specifically, the feeding bearing 25 can be a linear motion bearing from the prior art, which cooperates with the cylindrical shaft to achieve linear movement of the feeding suction cup 23. The feeding suction cup 23 can form a negative pressure by communicating with the pneumatic component 16 to adsorb the cardboard 60. The cardboard hopper 21 can be formed by having an opening in the middle and vertical baffles installed on the four sides. A baffle of a certain length needs to be set at the bottom opening to support the cardboard 60 and prevent it from falling off. Understandably, since the feeding suction cup 23 needs to pick up the cardboard 60 from the opening, the length of the baffle should not be too long. It needs to be long enough to prevent the cardboard 60 from falling off while still allowing it to be picked up by the feeding suction cup 23.

[0038] like Figure 4As shown, preferably, the feeding mechanism 22 is further provided with a shifting push plate 26, a shifting motor 27, and a shifting screw 28. The shifting motor 27 and the shifting screw 28 are respectively installed on the worktable 11. The nut of the shifting screw 28 is fixedly connected to the shifting push plate 26, and its screw is connected to the output shaft of the shifting motor 27, thereby causing the shifting motor 27 to operate. The shifting push plate 26 is moved laterally by the shifting screw 28, thereby pushing the cardboard 60 to be processed to the preset position of the feeding station 12.

[0039] Specifically, the shifting screw 28 can be a ball screw from the prior art, typically composed of a screw, nut, steel ball, pre-press plate, reverser, dust collector, etc. Its function is to convert rotary motion into linear motion, allowing the shifting motor 27 to drive the shifting push plate 26 to move laterally, changing the position of the cardboard 60 so that it can be picked up by the subsequent transfer suction cup 46 and correctly placed on the carrier at the corresponding workstation. Understandably, after the feeding suction cup 23 picks up the cardboard 60 from the cardboard hopper 21, the feeding cylinder 24 moves downward to the preset position. Then, the feeding suction cup 23 releases the negative pressure, releasing the suction on the cardboard 60, allowing it to move laterally on the feeding suction cup 23 and be pushed by the shifting push plate 26 to the correct preset position, awaiting pickup by the transfer suction cup 46.

[0040] like Figure 6 and Figure 7 As shown, preferably, the folding assembly 300 is provided with a forming mechanism 310. The forming mechanism 310 is used to fold and form the middle inner support portion 63 of the cardboard 60, so that the middle inner support portion 63 of the cardboard 60 forms a preset inner support folding shape. The forming mechanism 310 is provided with a pressing bracket 311, a pressing cylinder 312, a pressing bearing 313, and a pressing cutter head 320. The pressing bracket 311 is fixed to the worktable 11. The pressing cylinder 312 and the pressing bearing 313 are respectively installed on the pressing bracket 311. The pressing cutter head 320 is movably connected to the pressing bracket 311 through the pressing bearing 313 and forms a transmission connection with the piston rod of the pressing cylinder 312, so that the pressing cylinder 312 operates and drives the pressing cutter head 320 to move a certain distance vertically, thereby performing a pressing operation on the inner support portion 63 of the cardboard 60 to be processed.

[0041] Specifically, since the cardboard 60 to be processed has been pre-cut at a preset position when it enters the equipment, the part that needs to be folded into an inner tray has been cut off, but it is still on the same plane as the cardboard 60. Therefore, the pressing head 320 can press down on the part that needs to be folded under the drive of the pressing cylinder 312, so that it is separated from the plane of the cardboard 60 and bent downward at a certain angle to form the shape of a folded inner tray.

[0042] like Figure 6 and Figure 7 As shown, preferably, the forming mechanism 310 is further provided with a transfer bracket 314, a transfer cylinder 315, and a transfer bearing 316. The transfer bracket 314 is fixed to the guide shaft of the lower bearing 313 and forms a transmission connection with the piston rod of the lower cylinder 312. The transfer cylinder 315 and the transfer bearing 316 are respectively installed on the transfer bracket 314. The lower cutting head 320 is movably connected to the transfer bracket 314 through the transfer bearing 316 and forms a transmission connection with the piston rod of the transfer cylinder 315.

[0043] Specifically, both the pressing bearing 313 and the transition bearing 316 can be linear bearings from existing products, forming a linear motion system used in conjunction with a guide shaft. This allows the corresponding guide shaft to achieve stable linear motion with the support of the linear bearing, enabling the connected components to move linearly synchronously. Since the material transfer assembly 40 needs to place the cardboard 60 onto or remove it from the forming carrier 330, the pressing head 320 needs to move upwards a certain distance after completing the pressing operation to avoid the material transfer assembly 40. Furthermore, the driving force for the downward movement of the pressing head 320 is different from the driving force for pressing the cardboard 60. Therefore, it is preferable to use a pressing cylinder 312 and a pressing bearing 313 to move the pressing head 320 from above to below, approaching or abutting against the cardboard 60. At the same time, a transfer cylinder 315 and a transfer bearing 316 are provided to apply a downward driving force to the downward pressure head 320, so that the downward pressure head 320 can perform a downward pressure operation on the inner support part 63 of the cardboard 60, so that it is bent by the downward pressure to form the inner support shape.

[0044] like Figure 7 As shown, preferably, the forming mechanism 310 is further provided with a pre-pressure plate 317, a pre-pressure bearing 318 and a pre-pressure spring 319. The pre-pressure bearing 318 is fixedly connected to the adapter bracket 314, the pre-pressure plate 317 is fixedly connected to the guide shaft of the pre-pressure bearing 318, and the pre-pressure spring 319 is sleeved on the guide shaft of the pre-pressure bearing 318, with one end abutting against the pre-pressure bearing 318 and the other end abutting against the pre-pressure plate 317.

[0045] Specifically, the pre-press plate 317 is provided with a pre-pressing through hole corresponding to the position of the pressing head 320. The pre-pressing through hole is used to avoid the pressing head 320. When the cardboard 60 to be processed is placed on the forming carrier 330, in order to avoid the cardboard 60 from shifting when the pressing head 320 performs the pressing and folding operation, resulting in defective products, the cardboard 60 can be pre-pressed and fixed by setting the pre-press plate 317 and the pre-pressing spring 319. After the cardboard 60 is fixed in position by the pre-press plate 317, it is then pressed and folded by the pressing head 320.

[0046] like Figure 7 and Figure 8 As shown, preferably, the pressing head 320 is provided with a folding cylinder 321, a folding knife holder 322, and a folding curved blade 323. The folding cylinder 321 is fixedly connected to the pressing head 320, the folding knife holder 322 is throttle-connected to the piston rod of the folding cylinder 321, and the folding curved blade 323 is fixedly connected to the folding knife holder 322. When the folding cylinder 321 is turned, it pushes the folding curved blade 323 to move to both ends of the pressing head 320, thereby causing the folding curved blade 323 to perform an outward folding operation on the inner support portion 63 of the cardboard 60.

[0047] Specifically, the folding cylinder 321 is preferably a double-rod hydraulic cylinder, a type of hydraulic cylinder with piston rods on both sides of the piston. It is generally bidirectionally hydraulically driven and can achieve constant-speed reciprocating motion. The structure of a hydraulic cylinder can be basically divided into five parts: cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device, and venting device. The piston rods on both sides can drive the folding blades 323 on both sides to move synchronously to both sides. If only the inner support portion 63 of the cardboard 60 is pressed downwards to fold it into a sidewall perpendicular to the plane of the cardboard 60, the inner support formed in this way is prone to deformation, either returning to its original shape or returning upwards a certain distance. This results in the inner support of the cardboard 60 being substandard in production, and in later use, when placing an SSD solid-state drive, the drive cannot be properly secured or protected.

[0048] Therefore, a folding cylinder 321 and a folding bend 323 can be installed at the pressing head 320. The folding cylinder 321 drives the folding bend 323 to move a certain distance to both sides. Then, the special shape of the folding bend 323 allows the side wall of the inner support of the cardboard 60 to continue to bend to both sides, so that the angle between the side wall and the cardboard 60 is greater than 90 degrees, thereby increasing the folding force and forming the correct inner support shape. Furthermore, the correct inner support shape can be maintained even after the pressing head 320 is removed or after the cardboard 60 is discharged.

[0049] like Figure 8 As shown, preferably, the folding blade 323 is provided with a triangular blade tip 327, which is used to fold the inner support portion 63 of the cardboard 60. The inclination angle of the triangular blade tip 327 is set to 40 to 45 degrees. Preferably, the inclination angle of the triangular blade tip 327 is set to 42 degrees.

[0050] Specifically, when folding the inner support component of the cardboard 60 and then bending it further to both sides, it is preferable to use the triangular blade tip 327 to push the sidewalls of the inner support, allowing it to bend to both sides. It is important to note that although the triangular blade tip 327 of the folding blade 323 is called a blade tip, it does not use the pointed end of the blade to cut the cardboard 60. Instead, it uses the hypotenuse of the triangle of the triangular blade tip 327 to push the sidewalls of the cardboard 60, causing it to bend further to both sides at a certain angle, thus forming a more stable inner support shape. Therefore, the inclination angle of the hypotenuse of the triangular blade tip 327 is preferably set to 40 to 45 degrees, and more preferably 42 degrees.

[0051] like Figure 8 and Figure 10 As shown, preferably, one end of the folding blade 323 is fixed to the folding blade holder 322, and the other end is provided with a first blade 324 and a second blade 325. A blade gap 326 is provided between the first blade 324 and the second blade 325. The blade gap 326 is used to avoid the limiting piece 62 on the cardboard 60, so that the limiting piece 62 will not be folded by the folding blade 323, and will remain on the same plane as the cardboard 60.

[0052] Specifically, when the SSD is installed in the inner support portion 63 of the cardboard 60, a limiting piece 62 can be provided on the cardboard 60 to prevent the hard drive from falling off. This ensures that when the folding assembly 300 is folded, it avoids the limiting piece 62, preventing it from being folded and losing its function. Therefore, a bend gap 326 can be provided between the two bends to avoid the limiting piece 62.

[0053] like Figure 9 , Figure 10 and Figure 13 As shown, preferably, the forming mechanism 310 is further provided with a forming carrier 330 and a bending pallet 331. The forming carrier 330 is fixed to the worktable 11, and the bending pallet 331 is installed on the forming carrier 330 and is provided with a bending bevel 332 that matches the folding blade 323, so that the inner support part 63 of the cardboard 60 is folded between the bending bevel 332 and the folding blade 323 under the folding operation of the folding blade 323, forming a folded shape.

[0054] Specifically, the bending pallet 331 mainly supports the cardboard 60 to be processed, allowing the pressing blade 320 to press down on the cardboard 60. Simultaneously, to facilitate a larger angle bend of the inner support portion 63 of the cardboard 60 by the triangular blade tip 327 of the bending blade 323, a bending bevel 332 can be provided on one side corresponding to the triangular blade tip 327. This bending bevel 332 abuts against the side wall of the inner support portion 63, allowing the side wall to be bent to a preset angle without causing excessive bending and damaging the cardboard 60.

[0055] like Figure 9 , Figure 10 , Figure 12 and Figure 13 As shown, preferably, the forming mechanism 310 is further provided with a pallet guide rail 333, a pallet slider 334, and a pallet cylinder 335. The pallet guide rail 333 and the pallet cylinder 335 are respectively fixed to the forming carrier 330. The pallet slider 334 and the pallet guide rail 333 cooperate with each other to form a sliding connection. The bending pallet 331 is fixed to the pallet slider 334 and is driven to the piston rod of the pallet cylinder 335, so that the pallet cylinder 335 operates and drives the bending pallet 331 to move laterally a certain distance.

[0056] Specifically, by configuring the bending tray 331 to move laterally, a side thickness compensation function can be achieved. That is, using the crank portion of the folding blade 323, it can extend into the bottom of the bending bevel 332 when moving laterally. The bending tray 331 can move accordingly based on the thickness of the side wall of the inner support portion 63, thereby compensating for the thickness of the side wall of the inner support portion 63 of the cardboard 60. This allows cardboard of various thicknesses to be folded. It also ensures that the force on the side wall of the inner support portion 63 is uniform during folding, improving the quality of the inner support of the cardboard 60.

[0057] Meanwhile, the bending pallet 331 can move laterally a certain distance to both sides and can also detach from the inner support part 63 after the cardboard 60 is folded and formed, so that the formed cardboard 60 can be normally picked up, thereby facilitating the material transfer component 40 to pick up the folded cardboard 60. In addition, the bending pallet 331 is also provided with a limiting block 336. The limiting block 336 is positioned corresponding to the limiting piece 62 of the cardboard 60, thereby supporting the limiting piece 62 and preventing it from being bent.

[0058] like Figure 9 , Figure 10 , Figure 12 and Figure 13As shown, preferably, the forming mechanism 310 is further provided with an upper support block 337 and an upper support cylinder 338. The upper support cylinder 338 is fixedly connected to the forming carrier 330, and the upper support block 337 is throttle connected to the piston rod of the upper support cylinder 338, so that the upper support cylinder 338 operates and drives the upper support block 337 to move upward, thereby squeezing the inner support portion 63 of the folded cardboard 60 and folding it into a preset inner support shape.

[0059] Specifically, to support the inner support portion 63 of the cardboard 60, an upper support block 337 can be provided. The upper support cylinder 338 drives the upper support block 337 to a preset height, ensuring that the folded inner support portion 63 rests precisely against the upper support block 337, preventing deformation of the inner support portion 63 after being pressed down, which would affect the final output quality of the inner support cardboard 60. Furthermore, to further fold the inner support portion 63, the bending plate 331 can be moved a certain distance to both sides, allowing the upper support block 337 to further compress the folded inner support portion 63 of the cardboard 60, forming a more accurate preset folded shape and preventing the inner support portion 63 from returning to its original position under the tension of the cardboard 60. Understandably, the further folding and compressing of the upper support block 337 can be adjusted according to different parameters such as the material, hardness, or thickness of the cardboard 60. For example, some cardboard 60 that is not easy to spring back and deform does not need to be folded and squeezed again, while some cardboard 60 that is easier to spring back and deform needs to be folded and squeezed again to increase the strength of the folding of its inner support part 63.

[0060] like Figure 11 As shown, preferably, the folding assembly 300 further includes a folding mechanism 340, which is used to fold the four sides 64 of the cardboard 60 to form a preset folded shape. The folding mechanism 340 includes a folding bracket 341, a folding cylinder 342, a folding bearing 343, a folding pressure plate 344, a folding stop block 345, and a folding bending plate 346. The folding bracket 341 is fixed to the worktable 11. The folding cylinder 342 and the folding bearing 343 are respectively fixed to the folding bracket 341. The folding pressure plate 344 is movably connected to the folding bracket 341 through the folding bearing 343 and forms a transmission connection with the piston rod of the folding cylinder 342. The folding stop block 345 is elastically connected to the folding pressure plate 344. The folding bending plate 346 is fixed to the folding pressure plate 344.

[0061] Specifically, the folding cylinder 342 operates, driving the folding pressure plate 344 to move downward, so that the folding block 345 can abut against the middle of the cardboard 60, and at the same time, the folding bending plate 346 can perform a bending operation on the four sides 64 of the cardboard 60, so that the four sides 64 of the cardboard 60 are folded to form a preset folded shape.

[0062] like Figure 11 As shown, preferably, the folding mechanism 340 is further provided with a folding carrier 350, a folding support block 351, a pressing cylinder 352, and a pressing block 353. The folding carrier 350, the folding support block 351, and the pressing cylinder 352 are respectively installed on the worktable 11. The folding support block 351 is used to abut the lower part of the cardboard 60. The pressing block 353 is driven to the piston rod of the pressing cylinder 352, so that the pressing cylinder 352 operates and drives the pressing block 353 to perform a reinforced folding operation on the four sides 64 of the bent cardboard 60, so that the four sides 64 of the cardboard 60 form a preset folded shape.

[0063] Specifically, since the previous forming station 13 has already folded and formed the inner support part 63 of the cardboard 60 into a downward folded inner support shape, a countersunk hole needs to be set in the middle position of the folded edge support block 351 corresponding to the inner support part, so that the folded inner support part can sink into the countersunk hole and prevent it from being squeezed and deformed by the folded edge support block 351.

[0064] Secondly, since the folding assembly 300 has four folding sections with different cardboard 60 shapes or different inner tray shapes, it can fold different cardboard 60 or inner tray shapes. However, the folding mechanism 340 does not have four corresponding different folding sections, so the corresponding folding components need to be replaced at the folding mechanism 340. That is, after selecting the appropriate forming mechanism 310 according to the required folding cardboard 60 or inner tray shape, the folding mechanism 340 also needs to be replaced accordingly, such as replacing the folding stop block 345, the folding bending plate 346, the folding carrier 350, the folding support block 351, and the folding stop block 345, etc.

[0065] like Figure 2 and Figure 3 As shown, preferably, the material transfer assembly 40 is provided with a first material transfer mechanism 41 and a second material transfer mechanism 42. The first material transfer mechanism 41 is used to pick up the paperboard 60 to be processed from the feeding station 12 and move it to the forming station 13. The second material transfer mechanism 42 is used to pick up the folded paperboard 60 from the forming station 13 and move it to the folding station 14.

[0066] Specifically, since the paperboard 60 needs to be transferred at different workstations, two sets of transfer mechanisms can be set up to transfer the paperboard 60 in different zones.

[0067] like Figure 3 and Figure 5As shown, preferably, the material transfer assembly 40 includes a material transfer slide rail 43, a material transfer slider 44, a material transfer cylinder 45, a material transfer suction cup 46, a synchronous belt 47, a material transfer pulley 48, and a material transfer motor 49. The material transfer slide rail 43 and the material transfer motor 49 are respectively fixed to the worktable 11. The material transfer pulley 48 is rotatably connected to the worktable 11. One end of the synchronous belt 47 is sleeved on the material transfer pulley 48, and the other end is drivenly connected to the output shaft of the material transfer motor 49. The material transfer slider 44 is fixed to the synchronous belt 47 and cooperates with the material transfer slide rail 43 to form a sliding connection. The material transfer cylinder 45 is fixed to the material transfer slider 44, and the material transfer suction cup 46 is fixed to the piston rod of the material transfer cylinder 45.

[0068] Specifically, the transfer motor 49 operates, driving the synchronous belt 47 to rotate, thereby causing the transfer slider 44 to move synchronously, which in turn drives the transfer cylinder 45 and the transfer suction cup 46 to move between various workstations. The operation of the transfer cylinder 45 can drive the transfer suction cup 46 to move up and down, thereby performing the operation of picking up or putting down the cardboard 60 at the workstation. The transfer suction cup 46 can also be connected to the pneumatic component 16 in the prior art through a pipeline, thereby providing negative pressure air to the transfer suction cup 46 so that it can normally pick up or put down the cardboard 60. In addition, it can be understood that the first transfer mechanism 41 and the second transfer mechanism 42 are respectively equipped with corresponding transfer slide rails 43, transfer sliders 44, transfer cylinders 45, transfer suction cups 46, synchronous belts 47, transfer pulleys 48 and transfer motors 49, so that both can pick up and move the cardboard 60.

[0069] like Figure 3 As shown, preferably, the discharge assembly 50 is provided with a transverse slide rail 51, a transverse slider 52, a transverse cylinder 53, a discharge suction cup 54, and a discharge cylinder 55. The transverse slide rail 51 and the transverse cylinder 53 are respectively fixed to the worktable 11. The transverse slider 52 is drivenly connected to the piston rod of the transverse cylinder 53 and cooperates with the transverse slide rail 51 to form a sliding connection. The discharge cylinder 55 is fixed to the transverse slider 52, and the discharge suction cup 54 is fixed to the piston rod of the discharge cylinder 55.

[0070] Specifically, the operation of the transverse cylinder 53 drives the transverse slider 52 to move laterally along the transverse slide rail 51, thereby causing the discharge cylinder 55 to move laterally synchronously, so that the discharge suction cup 54 moves between the folding station 14 and the unloading station 15. The operation of the discharge cylinder 55 drives the discharge suction cup 54 to move up and down, thereby performing suction or unloading operations on the cardboard 60 at the station. Similarly, the discharge suction cup 54 can also be connected to the pneumatic assembly 16 through a pipeline to provide negative pressure air for suction or unloading operations.

[0071] Secondly, the unloading station 15 can be set outside the frame 10 so that the folded cardboard 60 can be placed into the corresponding area or container, waiting for the next step or station operation.

[0072] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
