Description

Technical Field

[0001] This utility model relates to the field of flip paper take-up machine technology, specifically an intelligent flip paper take-up machine that prevents deviation. Background Technology

[0002] In industries such as packaging manufacturing, printing, and e-commerce logistics, cardboard (such as cardboard box blanks and packaging box shells) is the core packaging carrier. Its production and processing often involves "conveyance-flipping-positioning-subsequent processing" and other steps. As a key piece of equipment connecting the preceding and following processes, cardboard flipping equipment needs to achieve three core functions: First, accurate reception and positioning, stably receiving cardboard from the conveyor line, avoiding cardboard offset and misalignment, and ensuring the accuracy of subsequent flipping; second, safe and stable flipping, accurately flipping horizontally conveyed cardboard to a vertical position or a specific angle (such as 180° flipping), without the cardboard falling off or deforming during the process, meeting the posture requirements of subsequent processes; and third, efficient continuous operation, realizing the "receive-flipping-output-reset" cyclical operation, adapting to the high-speed production needs of assembly lines.

[0003] There is a certain positional deviation in the paperboard conveying process (such as the paperboard shifting by 5-8mm due to belt misalignment). The existing equipment does not have a pre-positioning compensation mechanism and directly accepts the deviated paperboard. When it is flipped later, the initial positional deviation will cause the paperboard to be in the wrong posture after flipping (such as the paperboard tilting more than 5° when outputting vertically), which requires manual readjustment and affects the work efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 6 This utility model provides a technical solution: Example 1

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, Core structural connection and cooperation: The slide 31 of the flipping mechanism 3 is a steel frame, which is fixed inside the housing 1 by bolts. It is slidably adapted to the first slider 34 by the slide rod to ensure that the first slider 34 rises and falls smoothly along the slide 31. The frame is fixed to the outside of the first slider 34 by welding. The servo motor 35 is installed on the frame by bolts. The output end of the servo motor 35 is connected to the rotating shaft 36 by the flexible coupling. The two ends of the rotating shaft 36 are respectively installed in the bearing seats of the first slider 34 and the second slider 307 by deep groove ball bearings. The bearing seats are fixed to the two sliders by bolts to ensure that the rotating shaft 36 rotates flexibly and without radial offset.

[0023] Two plates are welded to the outside of the rotating shaft 36. A U-shaped frame 37 is welded to the bottom of the plate. The two U-shaped frames 37 are symmetrically distributed and used to support the paperboard. An L-shaped seat 38 is welded to the outside of the carriage 31. A T-shaped groove is opened inside the L-shaped seat 38. A sliding adapter limit plate 39 slides in the groove to block and limit the front end of the paperboard.

[0024] A crossbeam 30 is welded to the outer plate of the rotating shaft 36. A top block 301, which is a metal block, is welded to the top of the crossbeam. An elastic telescopic rod 302 is welded to the bottom of the top block 301. The elastic telescopic rod 302 passes through the through hole on the surface of the rotating shaft 36. A wedge block 303 is welded to the bottom end. The curved part of the wedge block 303 faces the direction of the paper shell. In the initial state, the elastic telescopic rod 302 is in a slightly compressed state, so that the wedge block 303 has a certain pre-pressure.

[0025] Work process: Paperboard conveying and receiving: The external conveyor line conveys the paperboard into the housing 1. At this time, one of the U-shaped material frames 37 is in a horizontal receiving position, and the paperboard falls into the U-shaped material frame 37. At the same time, the small cylinder in the L-shaped seat 38 drives or manually moves the limiting plate 39 upward along the T-shaped groove until the limiting plate 39 fits against the front end of the paperboard, preventing the paperboard from moving forward and avoiding the paperboard from exceeding the range of the U-shaped material frame 37.

[0026] Initial compression and limiting: Under its own elastic force, the elastic telescopic rod 302 pushes the wedge block 303 downward. The curved part of the wedge block 303 is pressed and adhered to the upper surface of the front end of the paper shell. The elastic pressure is used to press the front end of the paper shell tightly against the bottom of the U-shaped material frame 37, further fixing the position of the paper shell and preventing the paper shell from loosening or shifting left and right during subsequent lifting and lowering. Example 2

[0027] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the core structure connections and fit relationships are as follows: A vertical rod 32 is welded to the outside of the slide 31. An electromagnet 33 is fixed inside the vertical rod 32 by bolts. The electromagnet 33 is connected to an external power source through wires, which can realize energization and activation, and de-energization and release. A circular block is fixed inside the second slider 307 by bolts. A magnetic block 314 is glued to the outside of the circular block. The magnetic block 314 and the electromagnet 33 are positioned opposite each other and can generate a repulsive force after being energized. A guide hole is opened inside the rotating shaft 36. A sliding adapter variable diameter column 312 is fitted inside the hole. It is a metal column with a diameter of 30cm at one end and 25cm at the other end. A spring 313 is sleeved on the outside of the variable diameter column 312. One end of the spring 313 is welded to the step of the variable diameter column 312, and the other end is welded to the circular block inside the second slider 307. In the initial state, the spring 313 is in a naturally extended state.

[0028] The top of the second slider 307 is welded with a fixed shaft 304. The outer side of the fixed shaft 304 is fitted with a magnetic shielding plate 305, which is a magnetic shielding material plate with a thickness of 3mm. The magnetic shielding plate 305 can slide up and down along the fixed shaft 304. The outer side of the rotating shaft 36 is welded with a cam plate 306, which is a metal plate with a cam-shaped outline. The protruding part of the cam plate 306 can contact the bottom of one end of the magnetic shielding plate 305, pushing the magnetic shielding plate 305 to move up and down.

[0029] A sleeve plate 308 is welded to the center of the rotating shaft 36. An electric push rod 309 is bolted to the top of the sleeve plate 308. A limiting claw 300 is welded to the top of the electric push rod 309 through a connecting plate. The limiting claw 300 is a metal claw, and two are symmetrically distributed. The limiting claw 300 extends through the through hole at the top of the sleeve plate 308 to the bottom and can move up and down under the drive of the electric push rod 309. A reset switch 311 is bolted to the bottom of the sleeve plate 308. The reset switch 311 is connected to the control system of the electric push rod 309 through a wire and is used to control the start and stop of the electric push rod 309.

[0030] An airbag 315, made of rubber, is installed inside the rotating shaft 36. One end of the airbag 315 contacts the reducing column 312, and the other end is connected to the reset sliding frame 316 through a plastic tube. The reset sliding frame 316 is a telescopic plastic frame. A toggle rod 317 is welded to the bottom of the reset sliding frame 316. The outer end face of the toggle rod 317 faces the reset switch 311 and can contact and press with the reset switch 311.

[0031] Working process: Servo motor 35 drives slider 1 34 and slider 2 307 to rise synchronously along the slide bar of slide frame 31, driving U-shaped material frame 37 and paperboard to rise; when it rises to the set position, electromagnet 33 is energized to generate a magnetic field, which generates a repulsive force with magnetic block 314 inside slider 2 307. The repulsive force pushes magnetic block 314 and round block inward, round block squeezes spring 313, and at the same time pushes variable diameter column 312 to move into the rotating shaft 36. Variable diameter column 312 squeezes air bag 315. After being compressed, air bag 315 releases internal air... The body enters the reset sliding frame 316 through the pipe, pushing the reset sliding frame 316 to extend. The reset sliding frame 316 drives the toggle rod 317 to move outward until the toggle rod 317 presses the reset switch 311. After the reset switch 311 is triggered, it sends a signal to the electric push rod 309 control system. The electric push rod 309 starts and extends downward, pushing the limit claw 300 to move down. The bottom of the limit claw 300 is attached to the top of the front and rear ends of the paper shell, which performs secondary limiting on the paper shell to prevent the paper shell from detaching from the U-shaped material frame 37 due to centrifugal force when flipping.

[0032] When the paper rises to the required flipping height for the second time, the servo motor 35 starts, driving the rotating shaft 36 to rotate 180°, which in turn drives the U-shaped material frame 37 to flip synchronously with the paper shell, flipping the paper shell that was originally horizontally supported to the vertical output position. During the flipping process, the limiting claw 300 always presses the front and rear ends of the paper shell, and the wedge block 303 maintains elastic compression on the front end of the paper shell. Multiple limiting measures ensure that the paper shell does not shift or fall off. Example 3

[0033] like Figure 3 , Figure 5 and Figure 6 As shown, After the rotating shaft 36 rotates 180°, it drives the cam plate 306 to rotate synchronously. The protruding part of the cam plate 306 rotates from the bottom to the top, and the round part rotates to the bottom. At this time, the bottom of one end of the magnetic blocking plate 305 is no longer squeezed by the protruding part of the cam plate 306. Under its own gravity, it moves downward along the fixed axis 304 until the magnetic blocking plate 305 is inserted between the electromagnet 33 and the magnetic block 314, isolating the magnetic fields of the two and the repulsive force is greatly reduced.

[0034] After the repulsive force is reduced, the spring 313 resets under its own elastic force, pushing the variable diameter column 312 to move outward of the rotating shaft 36. The air bag 315 is no longer squeezed, and the gas in the reset sliding frame 316 is drawn back. The reset sliding frame 316 contracts, driving the toggle lever 317 to reset, no longer squeezing the reset switch 311. After the reset switch 311 is reset, it sends a signal to the electric push rod 309. The electric push rod 309 contracts upward, driving the limit claw 300 to move upward, releasing the limit on the front and rear ends of the paper shell.

[0035] The flip door 2 inside the housing 1 is opened by the cylinder, revealing the paper output port; external pushing equipment, such as push rod cylinder, pushes the paper out of the U-shaped material frame 37, and the paper enters the subsequent paper receiving process through the output port; then, the servo motor 35 drives the rotating shaft 36 to rotate 180°, so that the U-shaped material frame 37 returns to the horizontal receiving position, and at the same time another set of U-shaped material frames 37 begins to receive the next paper, entering the next work cycle.

[0036] The working principle of this utility model is as follows: After the paperboard is conveyed into the housing 1, it first enters the U-shaped material frame 37 of the flipping mechanism 3. At this time, the limiting plate 39 in the L-shaped seat 38 on the outside of the slide 31 slides along the T-shaped groove to initially block and limit the front end of the paperboard, preventing the paperboard from shifting when it moves upward later. At the same time, the elastic telescopic rod 302 at the bottom of the crossbeam 30 drives the wedge block 303 to move downward. The curved part of the wedge block 303 is pressed and adhered to the front end of the paperboard. The elastic pressure of the elastic telescopic rod 302 is used to further fix the paperboard, preventing the paperboard from loosening or shifting before flipping, thus laying a stable foundation for anti-adhesion flipping.

[0037] The servo motor 35 slides along the slide 31 via the first slider 34 to adjust the lateral position of the rotating shaft 36 so that the U-shaped material frame 37 is aligned with the paperboard receiving and output path; the servo motor 35 drives the rotating shaft 36 to rotate, causing the U-shaped material frame 37 and the paperboard to flip synchronously, and the flipping action outputs the paperboard that is below from above.

[0038] The rotating shaft 36 moves the variable-diameter column 312 inside the sliding adapter upwards, and the magnetic block 314 connected to the variable-diameter column 312 via a circular block moves upwards synchronously until it reaches a height that generates a repulsive force with the electromagnet 33. After the electromagnet 33 inside the vertical rod 32 is energized, it generates a magnetic field, which, together with the magnetic block 314 inside the second slider 307, generates a repulsive force. At the same time, the paper shell is no longer limited by the limiting plate 39 at this height, and under the magnetic repulsive force, the variable-diameter column 312 moves inwards and squeezes the airbag 315. The gas inside the airbag 315 will enter the reset sliding frame 316 through the tube and stretch it. The toggle rod 317 connected to the bottom of the reset sliding frame 316 will move outward accordingly until it pushes the reset switch 311, thereby driving the electric push rod 309 to move downward. The electric push rod 309 pushes the limiting claw 300 to move downward, and after passing through the sleeve plate 308, it performs secondary limiting on the front and rear ends of the paper shell to prevent the paper shell from detaching from the U-shaped material frame 37 under the action of centrifugal force.

[0039] After the cardboard moves up and flips, the rotating shaft 36 drives the cam plate 306 to flip synchronously, and the protruding part at the top flips to the bottom, while the round part moves to the top. At this time, the magnetic blocking plate 305 is no longer squeezed by the protruding part of the cam plate 306, and moves along the fixed axis 304 toward the second slider 307 until the magnetism between the magnetic block 314 and the electromagnet 33 is reduced to the point that it can no longer generate repulsive force. The flip door 2 inside the housing 1 opens, revealing the cardboard output port. At this time, the electric push rod 309 drives the limiting claw 300 to move upward to release the limit. The wedge block 303 resets under the action of the elastic telescopic rod 302. Finally, the airbag 315 re-draws the gas inside the reset sliding frame 316 into its interior. At the same time, under the automatic reset of the reset sliding frame 316, the toggle rod 317 no longer squeezes the reset switch 311. Then the reset switch 311 resets, and at the same time, the electric push rod 309 resets, so that the limiting claw 300 no longer limits the two sides of the paper shell, and the paper shell is pushed out by the external push device.
