Description

Technical Field

[0001] This utility model relates to the field of die-cutting and hot stamping technology, specifically to a flipping plate device. Background Technology

[0002] In die-cutting and hot stamping equipment, different die-cutting frames need to be replaced due to the different products being processed. Usually, the replacement process is done manually. First, the original frame is pulled out, lifted to the designated storage position, and then replaced with a frame suitable for the new product, which is then lifted back into the corresponding station in the equipment.

[0003] Chinese utility model patent publication number "CN104400773B" discloses a plate frame storage unit and its working method, including a flip-up frame, a drive system, a lead screw transmission mechanism, a plate frame storage compartment, and a control system. The flip-up frame is connected to the drive system via the lead screw transmission mechanism. The drive system is connected to the control system. The plate frame storage compartment is located within the range of the flip-up frame. The working method is as follows: unused plate frames are pulled from the die-cutting station onto the flip-up frame; driven by the drive system, the plate frames move upward to the plate frame storage compartment; unused plate frames are pushed into the designated storage station; the drive system transports the flip-up frame to the storage station for replacing the plate frames and then stops, pulling the replacement plate frames onto the flip-up frame; the replacement plate frames are pushed into the die-cutting station to complete the replacement of the die-cutting plate frames.

[0004] However, according to paragraphs

[0026] to

[0041] of the instruction manual for the aforementioned board frame storage unit, the board frame needs to be moved from the die-cutting station into the flip-board frame and then moved upward along the guide rail to the board frame storage compartment before it can be placed in the storage compartment. Then, the replacement board frame is pulled into the flip-board frame, and the drive system drives the flip-board frame to reset, pushing the replacement board frame back into the die-cutting station. The board frame replacement process is lengthy and cannot meet the need for rapid board frame replacement. At the same time, the overall structure is relatively complex, making maintenance and repair difficult.

[0005] Secondly, the die-cutting machine usually has a die-cutting steel plate at the lower die to provide rigid support and ensure the stability and accuracy of the cutting or creasing process. However, the aforementioned plate frame storage unit can only store and replace the plate frame, and cannot simultaneously and quickly replace the die-cutting steel plate, which is quite inconvenient.

[0006] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0007] The purpose of this invention is to provide a simple flipping device that allows for quick replacement of the frame and die-cut steel plate, in order to solve the above-mentioned problems existing in the prior art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a flipping device, including a flipping base, a flipping frame, and a changing chamber, wherein the flipping frame and the flipping base are rotatably connected, characterized in that: the changing chamber is rotatably connected to the flipping frame, the plate frame and the die-cut steel plate are disposed in the changing chamber and are slidably connected to the changing chamber, and the changing chamber rotates around the hinge point with the flipping frame, thereby driving the plate frame to flip up and down.

[0009] By adopting the above technical solution: when it is necessary to replace the plate frame or die-cut steel plate, the plate frame or die-cut steel plate is pulled out from the die-cutting machine and placed in the plate changing chamber. Then, the plate changing chamber is rotated to align the plate frame or die-cut steel plate to be replaced in the plate changing chamber with the die-cutting machine. The replacement plate frame or die-cut steel plate can then be moved into the die-cutting machine. The plate changing chamber and the flipping frame rotate to allow the plate frame to be engaged and rotated in the plate changing chamber, avoiding the complicated pulling out, lifting and pushing steps in traditional equipment. This significantly shortens the replacement time of the plate frame or die-cut steel plate. At the same time, it reduces the complexity of the overall device, facilitates daily maintenance and troubleshooting, and enhances the stability and reliability of the equipment.

[0010] The aforementioned flipping device can be further configured as follows: the flipping compartment includes two sets of symmetrically distributed flipping side beams and several sets of support rods for connecting the two flipping side beams. The two sets of flipping side beams form a board-laying cavity with openings at both ends. Several sets of flipping slide plates are distributed at intervals within the board-laying cavity. The flipping slide plates separate the flipping side beams to form several sets of board frame slide grooves. The board frame is slidably disposed within the board frame slide grooves. The board frame slide grooves are provided with flipping slide rails and rear stops. The flipping slide rails and rear stops can abut against the board frame to prevent the board frame from detaching from the board frame slide grooves.

[0011] By adopting the above technical solution: the plate changing chamber is formed by two sets of flip-plate side beams and support rods to form a plate-laying cavity with openings at both ends. The flip-plate slide plate divides the plate-laying cavity into multiple plate frame slide grooves, allowing the plate frames to slide smoothly along the slide grooves. The flip-plate slide rail and the rear stop block limit and abut against the plate frames respectively, effectively preventing the plate frames from coming out of the slide grooves during flipping or moving. When replacing the plate frames, you only need to push the plate frames in or pull them out along the slide grooves, without the need for complicated lifting, transfer and resetting steps, which greatly shortens the plate frame replacement time. At the same time, the overall structure is compact and the components are simplified, which reduces the equipment manufacturing and maintenance costs and improves the practicality and reliability of the flip-plate equipment.

[0012] The aforementioned flip-board device can be further configured such that: several sets of steel plate slide rails are distributed at intervals on the side wall of the flip-board slide, and a supporting protrusion extends outward from the middle of the steel plate slide rail. The supporting protrusion separates the steel plate slide rails to form a steel plate groove, and the die-cut steel plate slides in cooperation with the steel plate groove.

[0013] By adopting the above technical solution, the steel plate slide rail set on the side wall of the flip-board slide cooperates with the support protrusion plate extending in the middle to form a structurally stable steel plate slide groove, which allows the die-cut steel plate to slide smoothly into or out along the slide groove. The support protrusion plate not only serves to separate the slide groove, but also provides a reliable bearing surface for the die-cut steel plate, ensuring the positional stability of the die-cut steel plate during the flip-board flipping process, effectively preventing the die-cut steel plate from shifting or falling off, and allowing the die-cut steel plate to be replaced quickly without the need for complicated tools, which significantly improves the efficiency and convenience of the die-cut steel plate replacement operation.

[0014] The aforementioned flip-board device can be further configured such that: the side of the flip-board slide has several slide notches, and a slide bearing is provided in the slide notch; the slide bearing is rotatably connected to the flip-board side beam.

[0015] By adopting the above technical solution: the skateboard bearing protrudes from the flip board and is set in the board frame groove. When the board frame slides into the board frame groove, the skateboard bearing can contact the board frame and rotate relative to the board frame, thereby improving the smoothness of the board frame moving into the board changing compartment.

[0016] The aforementioned flip-plate device can be further configured such that: flip-plate fixing seats are provided on both sides of the flip-plate compartment, and a flip-plate rotating shaft is passed through the middle of the flip-plate fixing seat; one end of the flip-plate rotating shaft is rotatably engaged with the flip-plate frame, and the flip-plate compartment is linked with the flip-plate rotating shaft.

[0017] By adopting the above technical solution, the plate changing compartment achieves a stable rotational connection between the plate changing compartment and the flipping frame through the cooperation of the flipping fixing seats on both sides and the flipping rotating shaft in the middle. One end of the flipping rotating shaft is rotated with the flipping frame, and the other end is linked with the plate changing compartment, which allows the operator to easily drive the plate changing compartment to rotate around the shaft and complete the up and down flipping action of the carrying plate frame. This ensures the positioning accuracy and smooth movement of the plate frame during the replacement process, avoids the complex translation and lifting mechanisms in traditional equipment, significantly simplifies the plate frame replacement process, and improves replacement efficiency. At the same time, the rotating shaft connection method has a stable structure and good durability, reducing the maintenance frequency and cost in long-term use.

[0018] The aforementioned flip-plate device can be further configured such that: a limiting component is provided on the flip-plate frame, the limiting component includes a limiting cylinder and a limiting slider, a limiting slot is provided on the outer periphery of the flip-plate fixing seat, the limiting slider is linked with the limiting cylinder through a universal joint, the flip-plate frame is also provided with a slider seat, the slider seat is provided with a sliding groove, the limiting slider passes through the sliding groove and slides with the sliding groove, the limiting cylinder pushes the limiting slider to reciprocate within the sliding groove, causing the end of the limiting slider to pass into or out of the limiting slot.

[0019] By adopting the above technical solution, the limiting component drives the limiting slider to move precisely back and forth within the sliding groove of the slider seat via a limiting cylinder. This allows the end of the limiting slider to reliably enter or exit the limiting slot of the flip-plate fixing seat, achieving automatic locking and rapid release of the changing chamber after it has been flipped into position. The universal joint effectively compensates for installation errors between the limiting cylinder and the limiting slider, ensuring smoothness and reliability of the transmission process. This structure enables the changing chamber to achieve stable mechanical limiting at any flipping angle, effectively preventing accidental displacement or loosening of the plate frame during replacement, significantly improving the safety and stability of equipment operation. Simultaneously, the cylinder-driven automated locking method simplifies the operation process and further improves the efficiency of plate frame replacement.

[0020] The aforementioned flip-plate device can be further configured as follows: the flip-plate base is provided with a flip-plate turntable, the flip-plate frame is linked with the flip-plate turntable, the outer periphery of the flip-plate base is provided with several sets of flip-plate support feet, and the bottom of the flip-plate base is detachably connected with several sets of support feet.

[0021] By adopting the above technical solution: the flip-plate base is linked with the flip-plate frame via a flip-plate turntable, enabling the flip-plate frame to rotate smoothly and horizontally relative to the base, facilitating precise positioning of the plate-changing compartment to different die-cutting stations. Several flip-plate supports distributed around the outer perimeter of the flip-plate base cooperate with the detachable support feet at the bottom, providing a stable foundation for the entire flip-plate equipment. This effectively absorbs vibrations generated during operation. Simultaneously, the detachable design of the support feet allows for fine-tuning of the height, ensuring the equipment remains level and stable even under less-than-ideal ground conditions. This enhances the equipment's adaptability to different working environments, simplifies installation and leveling processes, and improves the overall structural reliability and service life.

[0022] The aforementioned flip-plate device can be further configured as follows: the flip-plate frame includes two sets of flip-plate columns and a flip-plate connecting plate. The flip-plate columns are detachably connected to the flip-plate turntable. One end of the flip-plate connecting plate is detachably connected to one set of flip-plate columns, and the other end is detachably connected to another set of flip-plate columns. The two sides of the plate changing chamber are respectively rotatably connected to the two sets of flip-plate columns. A rotating base plate is detachably connected to the flip-plate columns. Several sets of guide rail seats are detachably connected to the rotating base plate. Several sets of sliding guide rods are provided on the flip-plate turntable. The sliding guide rods are slidably engaged with the guide rail seats. The guide rail seats slide relative to the sliding guide rods, causing the plate changing chamber to reciprocate along the axial direction of the sliding guide rods.

[0023] By adopting the above technical solution: the flip-plate frame forms a stable frame structure through two sets of flip-plate columns and flip-plate connecting plates. The detachable connection between the flip-plate columns and the flip-plate turntable, as well as the detachable engagement between the flip-plate connecting plates and the flip-plate columns, gives the entire flip-plate frame modular assembly characteristics, facilitating transportation, installation, and subsequent maintenance. The cooperation between the rotating base plate and the guide rail seat allows the plate changing chamber to achieve precise axial movement through the sliding guide rod, ensuring the stability and positioning accuracy of the plate frame during the movement into and out of the die-cutting station. This not only realizes the axial displacement function of the plate changing chamber based on horizontal rotation, enabling the plate frame to accurately align with die-cutting stations at different positions, but also significantly reduces the maintenance complexity of the equipment through the detachable modular design, improving the flexibility and adaptability of equipment use, and effectively meeting the production needs for rapid plate frame replacement.

[0024] The beneficial effects of this utility model are as follows: by rotating the plate changing bin with the flipping frame, the plate frame and the die-cut steel plate can be directly flipped up and down within the plate changing bin through rotation, replacing the complex pulling out, lifting, transferring and resetting process in traditional equipment. Furthermore, the plate changing bin has multiple sets of plate frame slides and steel plate slides formed by the flipping slide plate and steel plate slide rail. With the help of the flipping slide rail, the rear stop block and the supporting protrusion, the plate frame and the die-cut steel plate can slide smoothly and be accurately positioned in the corresponding slides, effectively preventing them from shifting or falling off during flipping or moving, thus improving the stability of the plate frame loading and the safety of operation.

[0025] Meanwhile, a guide rail seat is set on the flip-plate frame to cooperate with the sliding guide rod on the flip-plate base. The drive device pushes the rotating base plate to drive the plate changing chamber to move back and forth along the axis of the sliding guide rod, thereby adjusting the position of the openings at both ends of the plate changing chamber and the die changing port of the die cutting machine, so that the plate frame or die-cut steel plate can be accurately extracted and placed.

[0026] In addition, the flip plate turntable installed on the flip plate base can rotate relative to the flip plate base to adjust the orientation of the plate changing compartment, so that the plate frame or die-cut steel plate can be quickly placed and replaced from the plate changing compartment, which significantly improves the convenience of changing the plate frame and die-cut steel plate.

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

The flip-board frame 2 is rotatably engaged with the flip-board base 1, and the plate changing chamber 3 is rotatably engaged with the flip-board frame 2. The plate frame 6 is placed inside the plate changing chamber 3 and is engaged with the plate changing chamber 3. The plate changing chamber 3 rotates around the hinge point with the flip-board frame 2, causing the plate frame 6 to flip up and down.

[0031] like Figure 2 As shown, the flip base 1 is equipped with a flip turntable 11, the flip frame 2 is linked with the flip turntable 11, the outer periphery of the flip base 1 is provided with several sets of flip legs 12, and the bottom of the flip base 1 is detachably connected with several sets of support feet 14.

[0032] like Figure 3 , Figure 4As shown, the flip-plate frame 2 includes two sets of flip-plate columns 21 and flip-plate connecting plates 22. The flip-plate columns 21 are detachably connected to the flip-plate turntable 11. One end of the flip-plate connecting plate 22 is detachably connected to one set of flip-plate columns 21, and the other end is detachably connected to another set of flip-plate columns 21. The two sides of the plate changing chamber 3 are respectively rotatably connected to the two sets of flip-plate columns 21. The flip-plate columns 21 are detachably connected to a rotating base plate 23. The rotating base plate 23 is detachably connected to several sets of guide rail seats 24. Several sets of sliding guide rods 13 are provided on the flip-plate turntable 11. The sliding guide rods 13 are slidably engaged with the guide rail seats 24. The guide rail seats 24 slide relative to the sliding guide rods 13, causing the plate changing chamber 3 to reciprocate along the axis of the sliding guide rods 13.

[0033] like Figure 5 As shown, the pallet changing compartment 3 includes two sets of symmetrically distributed flap side beams 31 and several sets of support rods 32 for connecting the two flap side beams 31. The two sets of flap side beams 31 form a pallet placement cavity 33 with openings at both ends. Several sets of flap sliding plates 34 are distributed at intervals within the pallet placement cavity 33. The flap sliding plates 34 separate the flap side beams 31 to form several sets of pallet frame sliding grooves 35. The pallet frame 6 is slidably disposed within the pallet frame sliding groove 35. The pallet frame sliding groove 35 is provided with a flap slide rail 351 and a rear stop block 352. The flap slide rail 351 and the rear stop block 352 can abut against the pallet frame 6 to prevent the pallet frame 6 from detaching from the pallet frame sliding groove 35.

[0034] The sidewall of the flip-board slide plate 34 is provided with several sets of steel plate slide rails 36 at intervals. A supporting protrusion 361 extends outward from the middle of the steel plate slide rail 36. The supporting protrusion 361 divides the steel plate slide rail 36 to form a steel plate slide groove 362. The die-cut steel plate 7 slides in cooperation with the steel plate slide groove 362.

[0035] The side of the flip-board slide 34 has several slide notches 341, and the slide notches 341 are equipped with slide bearings 342, which are rotatably connected to the flip-board side beam 31.

[0036] like Figure 6 As shown, the changing chamber 3 is provided with flip plate fixing seats 4 on both sides, and a flip plate rotating shaft 41 is inserted through the middle of the flip plate fixing seat 4. One end of the flip plate rotating shaft 41 is rotatably engaged with the flip plate frame 2, and the changing chamber 3 is linked with the flip plate rotating shaft 41.

[0037] The flip-plate frame 2 is equipped with a limiting component 5, which includes a limiting cylinder 51 and a limiting slider 52. A limiting slot 42 is opened on the outer periphery of the flip-plate fixing seat 4. The limiting slider 52 is linked to the limiting cylinder 51 through a universal joint 53. The flip-plate frame 2 is also equipped with a slider seat 54. The slider seat 54 has a sliding groove 541. The limiting slider 52 passes through the sliding groove 541 and slides in cooperation with the sliding groove 541. The limiting cylinder 51 pushes the limiting slider 52 to move back and forth in the sliding groove 541, causing the end of the limiting slider 52 to enter or move out of the limiting slot 42.

[0038] The working principle of this embodiment is as follows: the flip plate base 1 is placed on the side of the die-cutting machine through the support foot 14, the plate frame 6 is slidably arranged in the plate frame slide groove 35 of the plate changing chamber 3, the flip plate slide rail 351 and the rear stop block 352 contact the plate frame 6 and limit the plate frame 6, and the die-cutting steel plate 7 is slidably arranged in the steel plate slide groove 362.

[0039] When the die-cutting machine needs to replace the plate frame 6 or the die-cutting steel plate 7, the original plate frame 6 is pulled into the plate frame slide groove 35 in the middle of the plate replacement chamber 3. Then, the lifting drive device drives the rotating base plate 23 to move downward along the sliding guide rod 13. When the replacement plate frame 6 is aligned with the die-cutting machine, the replacement plate frame 6 is pushed into the die-cutting machine, thus realizing the quick replacement of the plate frame 6 and the die-cutting steel plate 7 in the die-cutting machine.

[0040] When it is necessary to replace the plate frame 6 or the die-cut steel plate 7 in the plate changing chamber 3, the limit cylinder 51 pulls the limit slider 52 to disengage from the limit slot 42 of the flip plate fixing seat 4. The plate changing chamber 3 rotates axially relative to the flip plate frame 2 around the central axis of the flip plate rotating shaft 41, which can quickly pull out or send the plate frame 6 and the die-cut steel plate 7 out of the plate changing chamber 3.

[0041] It should be noted that the plate frame slide 35 in the plate changing compartment 3 can be symmetrically distributed into two sets, which respectively hold two sets of plate frames 6 and die-cut steel plates 7, enabling the die-cutting machines at both ends to be replaced synchronously.

[0042] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
