Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper box processing technology, and in particular to a paper box molding plate flipping mechanism. Background Technology
[0002] Flatbed die-cutting machines achieve precise shaping of paper boxes through a combination of steel blade die-cutting and copper wire creasing technology, and are widely used in hanging and display packaging production. Their core technology lies in the precision control of the mold and the matching of pressure parameters, while also requiring coordination of subsequent processes such as hot stamping and lamination.
[0003] Currently, embossing plates are typically fixed to the bottom of the substrate with bolts. Replacement requires removing the entire substrate and embossing plate, hoisting it outside the machine using external tools, and then using a flipping device to flip the embossing plate onto the substrate to complete the replacement. This cumbersome process causes inconvenience in actual production. Utility Model Content
[0004] Therefore, it is necessary to provide a paper box mold plate flipping mechanism to address the problem of the cumbersome replacement of existing paper box mold plates.
[0005] A paper box molding plate flipping mechanism includes: a frame, a chain conveyor and a flipping mechanism, wherein the chain conveyor is fixedly connected to the inner side of the frame, and one end of the chain conveyor extends through the frame.
[0006] In one embodiment, the flipping mechanism includes a drive shaft rotatably connected to the inside of the frame, a servo motor fixedly connected to the frame and driven to the surface of the drive shaft, two flipping discs fixedly connected to the surface of the drive shaft, guide wheels rotatably connected to the opposite ends of the two flipping discs, the highest point of the guide wheels being flush with the highest point of the chain conveyor, and an adjustable positioning guide assembly fixedly connected to the top of the flipping disc, the adjustable positioning guide assembly being disposed above the guide wheels.
[0007] In one embodiment, mounting cavities are provided at opposite ends of the two rotating discs. The adjustable positioning guide assembly includes an electric cylinder fixedly connected to the top of the rotating disc. The output shaft of the electric cylinder extends through the interior of the mounting cavity. A positioning wheel is fixedly connected to the output shaft of the electric cylinder. The end of the positioning wheel facing away from the frame extends through the exterior of the mounting cavity.
[0008] In one embodiment, the output shaft of the electric cylinder is fixedly connected to a guide block that is slidably connected to the mounting cavity, and one end of the guide block is fixedly connected to a positioning wheel.
[0009] In one embodiment, the horizontal cross-sectional shapes of the guide block and the mounting cavity are both convex.
[0010] In one embodiment, the number of guide wheels is four, with every two guide wheels rotatably connected to one end of the same rotating disk, and the two guide wheels are symmetrically distributed on both sides of the positioning wheel.
[0011] In one embodiment, locking casters are fixedly connected to the four bottom corners of the frame.
[0012] In one embodiment, a counterweight placement box is welded to the inner side of the frame, and the drive source and servo motor of the chain conveyor are both located inside the counterweight placement box.
[0013] Beneficial effects
[0014] The aforementioned cardboard box molding plate flipping mechanism achieves automatic conveying and precise positioning of the substrate through the coordinated operation of the chain conveyor and the flipping mechanism. The servo motor drives the transmission shaft to drive the flipping plate to complete a 180° safe flip. The electric cylinder controls the positioning wheel to precisely engage with the arc groove. The entire process simplifies the traditional manual hoisting steps into automated operation, significantly shortening the molding plate replacement time.
[0015] The adjustable positioning guide assembly, through the sliding engagement of the guide block and the convex mounting cavity, combined with the symmetrical distribution design of four sets of guide wheels, enables the positioning wheels to adapt to the arc groove structure of substrates of different thicknesses, expanding the applicability of the flipping mechanism to diverse molds. At the same time, the closed-loop control system ensures the stability of the flipping process. Attached Figure Description

[0028] The following is combined with Figures 1-4 This invention describes the paper box molding plate flipping mechanism.
[0029] In one embodiment, a paper box molding plate flipping mechanism includes: a frame 100, a chain conveyor 200, and a flipping mechanism 300. The chain conveyor 200 is fixedly connected to the inner side of the frame 100, and one end of the chain conveyor 200 extends through the frame 100. To improve the stability of the flipping mechanism 300 flipping the substrate, arc grooves matching the positioning wheels 352 are opened on the top two sides of the substrate at corresponding positions. Lockable universal wheels 400 are fixedly connected to the four corners of the bottom of the frame 100. A counterweight placement box 500 is welded to the inner side of the frame 100, and the drive source and servo motor 320 of the chain conveyor 200 are both located inside the counterweight placement box 500.
[0030] like Figure 3 and Figure 4 As shown, the flipping mechanism 300 includes a drive shaft 310 rotatably connected to the inner side of the frame 100. A servo motor 320 fixedly connected to the frame 100 is drivenly connected to the surface of the drive shaft 310. Two flipping disks 330 are fixedly connected to the surface of the drive shaft 310. Guide wheels 340 are rotatably connected to the opposite ends of the two flipping disks 330. The highest point of the guide wheels 340 is flush with the highest point of the chain conveyor 200. An adjustable positioning guide assembly 350 is fixedly connected to the top of the flipping disk 330. The adjustable positioning guide assembly 350 is disposed above the guide wheels 340.
[0031] like Figure 4As shown, the two rotating disks 330 have mounting cavities 331 at their opposite ends. The adjustable positioning guide assembly 350 includes an electric cylinder 351 fixedly connected to the top of the rotating disk 330. The output shaft of the electric cylinder 351 extends into the interior of the mounting cavity 331. A positioning wheel 352 is fixedly connected to the output shaft of the electric cylinder 351. One end of the positioning wheel 352 facing away from the frame 100 extends into the exterior of the mounting cavity 331. A guide block 353 is fixedly connected to the output shaft of the electric cylinder 351 and slidably connected to the mounting cavity 331. One end of the guide block 353 is fixedly connected to the positioning wheel 352. The horizontal cross-sectional shapes of the guide block 353 and the mounting cavity 331 are both convex. There are four guide wheels 340. Every two guide wheels 340 are rotatably connected to one end of the same rotating disk 330. The two guide wheels 340 are symmetrically distributed on both sides of the positioning wheel 352.
[0032] Working Principle: The platen replacement operation of the flatbed die-cutting machine utilizes locking casters 400 to enable flexible movement and positioning of the device. After the chain conveyor 200 accurately receives the substrate, it actively transports the substrate into the flipping mechanism 300. The guide wheels 340 and positioning wheels 352 of the flipping mechanism 300 work together to center the substrate. When the electric cylinder 351 drives the positioning wheel 352 into the arc groove, the servo motor 320, through the drive shaft 310 and the flipping disc 330, achieves a 180° safe flip, making the platen face upwards for easy replacement. In the above process, the mechanical linkage between the chain conveyor 200 and the flipping mechanism 300 eliminates manual handling errors, the closed-loop control of the electric cylinder 351 and the servo motor 320 ensures flipping accuracy, and the adaptable structure of the guide wheels 340 and the positioning wheels 352 expands the compatibility of substrates of different thicknesses. The entire operation is standardized and safe, significantly reducing equipment downtime.
[0033] It should be noted that,
[0034] The chain conveyor 200 consists of the following core components:
[0035] Drive unit: includes electric motor, reducer, transmission sprocket and drive sprocket assembly, which drives the chain to rotate through power transmission.
[0036] Dual-chain system: Two high-strength, wear-resistant chains are used as traction components to improve load-bearing capacity and operational stability.
[0037] Tensioning device: The chain tension is adjusted by a screw tensioner, counterweight, or spring mechanism to prevent jumping or abnormal wear during operation.
[0038] Trough and guide rail: including the troughs on both sides of the machine head and tail, forming a guiding and conveying channel.
[0039] The working principle of the chain conveyor 200: The motor drives the double chain to move synchronously in a cycle through the reducer and sprocket assembly, and the double chain drives the base plate to slide horizontally.
[0040] The chain conveyor 200, servo motor 320, electric cylinder 351, and lockable caster wheel 400 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the chain conveyor 200, servo motor 320, and electric cylinder 351 are all powered by AC mains. The specific power supply method will be selected according to the situation and will not be elaborated here.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The above-described embodiments are merely illustrative 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 this utility model. 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 all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
