Description

Technical Field

[0001] This invention belongs to the field of automation equipment technology and relates to a paper folding machine that facilitates paper shaping. Background Technology

[0002] Paper folding machines are automated devices used to fold paper, frequently employed in the packaging industry. Flat packaging paper is folded to form a three-dimensional box, and the accuracy of the folds directly affects the final product appearance. Existing paper folding machines typically only perform simple folds, making the paper prone to curling edges and difficult to shape, thus impacting the quality of the final packaging. Therefore, a paper folding machine that facilitates paper shaping is needed to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a paper folding machine that facilitates paper shaping. By setting a shaping fixture and a compaction device, and working in conjunction with other devices, the paper is stabilized after folding, and the creases are deepened.

[0004] To achieve the above objectives, embodiments of the present invention provide a paper folding machine that facilitates paper shaping, comprising: a clamping device, a conveying device, a shaping device, a compacting device, an air blowing device, and a fixed base. The clamping device, the conveying device, the shaping device, the compacting device, and the air blowing device are all disposed on the fixed base and mechanically connected thereto.

[0005] The clamping device includes a first guide rail and a fixed baffle and a movable baffle disposed opposite to each other on the first guide rail. The movable baffle can move along the first guide rail according to the stacking width of the paper to be folded.

[0006] The transfer device includes a suction cup, which is disposed on one side of the fixed baffle. The transfer device drives the suction cup to pick up the paper to be folded and then moves the paper to be folded to the shaping device.

[0007] The shaping device includes a shaping fixture and a punching pin disposed directly above the shaping fixture. The punching pin can move vertically downward to press the paper to be folded on the shaping fixture into the interior of the shaping fixture and then fall into the compaction device.

[0008] The compaction device is positioned directly below the shaping fixture to compress and convey the paper.

[0009] The air blowing device is positioned above the shaping fixture to blow away the unshaped paper.

[0010] Furthermore, the clamping device further includes: a first motor and a synchronous belt. The first motor is mechanically connected to the fixed base and driven by the synchronous belt to move the movable baffle along the first guide rail. A plurality of the first guide rails are arranged in parallel in a groove shape to place the paper to be folded. The two ends of the plurality of first guide rails are mechanically connected to the fixed baffle and the movable baffle, respectively.

[0011] Furthermore, the shaping fixture includes: a concave surface of the paper mold, a connecting frame, and a vertical gap, wherein the concave surface of the paper mold is symmetrical about the vertical gap; a vertical base plate is provided on the fixed base; the shaping device further includes a first cylinder and a second guide rail, wherein the first cylinder is mechanically connected to the fixed base, and the second guide rail is vertically arranged on the base plate; the first cylinder is driven by the connecting frame on the shaping fixture through the second guide rail to realize the up and down movement of the shaping fixture.

[0012] Furthermore, the shaping device also includes a second cylinder, which is disposed on the base plate and driven by the stamping needle to realize the up and down movement of the stamping needle. The center of the stamping needle tip is aligned with the center of symmetry of the concave surface of the paper mold on the shaping fixture.

[0013] Furthermore, the compaction device includes a driving rubber roller, a driven rubber roller, a second motor, a conveyor belt, and a gear set. One end of both the driving and driven rubber rollers is mechanically connected to the gear set. The second motor is driven by the other end of the driving rubber roller via the conveyor belt to achieve opposite rotation of the driving and driven rubber rollers. A pressure gap is provided between the driving and driven rubber rollers, and the width of the pressure gap is smaller than the width of the vertical gap on the shaping fixture.

[0014] Furthermore, the transfer device also includes a vertical drive cylinder, a horizontal drive cylinder, a third guide rail, and a longitudinal drive cylinder. The longitudinal drive cylinder is connected to the vertical drive cylinder via the third guide rail. The horizontal drive cylinder is positioned above the vertical drive cylinder and is connected to it. The horizontal drive cylinder is also connected to the suction cup. The transfer device controls the movement of the suction cup in the up-down, left-right, and forward-backward directions through the actions of the horizontal drive cylinder, the vertical drive cylinder, and the longitudinal drive cylinder.

[0015] Furthermore, the transfer device also includes a first buffer and a second buffer, which are respectively disposed at both ends of the third guide rail to buffer the motion of the vertical drive cylinder.

[0016] Furthermore, it also includes a discharge device, which includes a first discharge port and a second discharge port. The first discharge port is located below the compaction device to allow the compressed paper to fall out from the first discharge port. The second discharge port is located below the side of the shaping fixture to allow the air blowing device to blow unshaped defective paper towards and out along the second discharge port.

[0017] Furthermore, the movable baffle is equipped with a pressure sensor for real-time monitoring of the paper to be folded.

[0018] Furthermore, it also includes: an outer shell, which is disposed around the periphery of the folding machine for supporting and protecting it, and the outer shell is mechanically connected to the fixed base.

[0019] This invention relates to a paper folding machine that facilitates paper shaping, and its beneficial effects are as follows:

[0020] The shaping fixture of this equipment has a vertical slit. The thickness of the folded paper is just enough to fall through the vertical slit and enter the next pressing process to deepen the crease. If the paper is not folded properly, it will not be able to fall through the vertical slit and will remain above the shaping fixture, where it will be blown away by the air blowing device. The design of the shaping fixture not only meets the needs of paper folding, but also plays a role in screening out defective products.

[0021] This equipment has a compaction device directly below the shaping fixture to further compact the folded paper, deepen the creases, and prevent the paper from recovering or curling during shaping, thus improving the final paper packaging effect.

[0022] In this device, the paper to be folded is placed between a fixed baffle and a movable baffle to prevent the paper from scattering. The movable baffle moves according to the amount of paper to be folded, limiting the width of the stacked paper to prevent it from scattering or falling over. The first guide rail set between the fixed baffle and the movable baffle not only limits the movement of the movable baffle but also serves as a rack for the paper to be folded, ensuring that each piece of paper picked up by the suction cup is in the same initial state.

[0036] The following is a detailed description of a paper folding machine that facilitates paper shaping, provided by an embodiment of the present invention, with reference to the accompanying drawings.

[0037] Example

[0038] Figure 1 This illustration shows one of the three-dimensional structural diagrams of a paper folding machine that facilitates paper shaping according to an embodiment of the present invention; Figure 2 This invention provides a schematic diagram of one of the three-dimensional structures of a paper folding machine that facilitates paper shaping according to an embodiment of the invention. Figure 3 It shows Figure 2 Enlarged view of part A in the middle; Figure 4 This is a second schematic diagram of the three-dimensional structure of a paper folding machine that facilitates paper shaping, provided by an embodiment of the present invention. Figure 5 This is the third schematic diagram of the three-dimensional structure of a paper folding machine that facilitates paper shaping, provided by an embodiment of the present invention. Figure 6 A schematic diagram of the three-dimensional structure of the shaping tooling provided in an embodiment of the present invention is shown; Figure 7 This is a second schematic diagram of the three-dimensional structure of a paper folding machine that facilitates paper shaping, provided by an embodiment of the present invention. For example... Figures 1 to 7As shown, the folding machine for easy paper shaping provided in this embodiment of the invention, by setting a shaping fixture and a compaction device, can make the paper stable after folding and deepen the creases. The folding machine for easy paper shaping provided in this embodiment of the invention includes: a clamping device, a conveying device, a shaping device, a compaction device, an air blowing device 16, and a fixed base 22. The clamping device, conveying device, shaping device, compaction device, and air blowing device 16 are all set at corresponding positions on the fixed base 22 and are mechanically connected to it, thereby establishing the overall layout structure of the folding machine and providing the corresponding support structure. The clamping device includes a first guide rail 4 and a fixed baffle 1 and a movable baffle 2 disposed opposite to each other on the first guide rail 4. The fixed baffle 1 and the movable baffle 2 are respectively disposed at both ends of the first guide rail 4. The movable baffle 2 can move along the first guide rail 4 according to the stacking width of the paper to be folded and appropriately press the paper to be folded. The paper to be folded is stacked on the first guide rail 4 between the fixed baffle 1 and the movable baffle 2. The paper to be folded can be fed manually or by industrial automation equipment. The feeding method is not specifically limited here.

[0039] The transfer device includes a suction cup 6, which is located on one side of the fixed baffle 1. The transfer device uses multiple corresponding drive cylinders to drive the suction cup 6 to pick up the paper to be folded and move the paper to be folded to the shaping device. The fixed baffle 1 has a slit, which allows the suction cup 6 to pass through the slit and contact and adhere to the paper to be folded, thus avoiding positional interference between the fixed baffle 1 and the suction cup 6.

[0040] The shaping device includes a shaping fixture 17 and a punch 14 positioned directly above the shaping fixture 17. The punch 14 can move vertically downward to press the paper to be folded on the shaping fixture 17 into the interior of the shaping fixture 17 and then fall onto the compaction device. The tip of the punch 14 is a blunt needle so as not to puncture the paper. Of course, the punch 14 can also be made of an elastic material such as rubber or nylon.

[0041] The compaction device is positioned directly below the shaping fixture 17 to compress and convey the paper; thereby deepening the creases on the paper and preventing it from recovering or curling during shaping, thus improving the final paper shaping and packaging effect.

[0042] The air blowing device 16 is positioned above the shaping fixture 17 to blow away the unshaped paper, which is also the unqualified paper.

[0043] The shaping fixture 17 in this embodiment of the invention is different from ordinary shaping fixtures. The shaping fixture 17 has a vertical slit 1703. The thickness of the folded paper is just enough to fall through the vertical slit 1703 and enter the next compaction process to deepen the crease. If the paper is not folded properly, it will not be able to fall through the vertical slit 1703 and will remain above the shaping fixture 17, where it will be blown away by the air blowing device 16. The design of the shaping fixture 17 not only meets the needs of paper folding, but also plays a role in screening out defective products.

[0044] In the paper folding machine for easy paper shaping provided in this embodiment of the invention, more specifically, the clamping device further includes: a first motor 3 and a synchronous belt 5. The first motor 3 is mechanically connected to the fixed base 22 and driven by the synchronous belt 5 to move the movable baffle 2 along the first guide rail 4, that is, the movable baffle 2 moves towards or away from the fixed baffle 1 along the first guide rail 4. The movable baffle 2 is mechanically fixedly connected to the synchronous belt 5, which is a belt drive. When the synchronous belt 5 rotates, it simultaneously drives the movable baffle 2 to move. Here, several first guide rails 4 are arranged in parallel in a groove shape to place the paper to be folded. The shape of the groove is adapted to the contour of the paper to be folded. Both ends of several first guide rails 4 are mechanically connected to the fixed baffle 1 and the movable baffle 2, respectively. It is worth noting that the first motor 3 and the movable baffle 2 can also be driven by a gear and rack mechanism, which can also achieve the moving effect of the movable baffle 2. The synchronous belt 5 can be replaced by a gear and rack mechanism.

[0045] Since the first guide rail 4 is located around the lower part of the fixed baffle 1 and the movable baffle 2, when the paper to be folded is placed between the fixed baffle 1 and the movable baffle 2, the first guide rail 4 also acts as a support, preventing the paper from scattering and ensuring that each piece of paper to be folded is in the same initial state when it is sucked away by the suction cup 6. Only when each piece of paper to be folded is in the same initial state when it is sucked away by the suction cup 6 will the folded shape formed in the next step on the shaping fixture 17 be the same. In order to achieve precise control of the paper to be folded, the movable baffle 2 is equipped with a pressure sensor 201 for real-time monitoring of the paper to be folded. Through pressure monitoring, the first motor 3 drives the synchronous belt 5 to adjust the position of the movable baffle 2 in real time.

[0046] In the paper folding machine for easy paper shaping provided in this embodiment of the invention, more specifically, the shaping fixture 17 includes: a paper mold concave surface 1701, a connecting frame 1702, and a vertical slit 1703. The paper mold concave surface 1701 is symmetrical about the vertical slit 1703, and the shape of the paper mold concave surface 1701 is adapted to the shape of the paper to ensure that the paper can fall into the vertical slit 1703 under the action of the punch 14. When the paper is placed on the paper mold concave surface 1701, the punch 14 moves down and applies a suitable force to the paper. The paper presses down on the paper mold concave surface 1701 to produce a crease. Under the action of gravity, the folded paper falls from the vertical slit 1703 into the compaction process. A vertical base plate 2201 is provided on the fixed base 22, which is used to fix the shaping fixture 17 and other components. The shaping device also includes a first cylinder 12 and a second guide rail 13. The first cylinder 12 is mechanically connected to the fixed base 22, and the second guide rail 13 is vertically arranged on the base plate 2201. The first cylinder 12 is driven by the connecting frame 1702 on the shaping fixture 17 through the second guide rail 13 to realize the up and down movement of the shaping fixture 17. The connecting frame 1702 is provided with a slider for sliding engagement with the second guide rail 13, while ensuring the smooth movement of the connecting frame 1702. It is worth noting that the paper mold concave surface 1701 in the shaping fixture 17 is detachable and replaceable to adapt to different paper sizes and meet various user needs.

[0047] In the paper folding machine for easy paper shaping provided in this embodiment of the invention, more specifically, the shaping device further includes a second cylinder 15. The second cylinder 15 is mounted on the base plate 2201 and is driven by the stamping needle 14 to realize the up-and-down movement of the stamping needle 14. The center of the needle tip of the stamping needle 14 is aligned with the center of symmetry of the concave surface 1701 of the paper mold on the shaping fixture 17. During operation, the first cylinder 12 drives the shaping fixture 17 to move up and down. The height of the shaping fixture 17 is adjustable. When the suction cup 6 picks up the paper, the height of the shaping fixture 17 can be adjusted so that the height of the shaping fixture 17 is lower than the height of the paper picked up by the suction cup 6, so that the suction cup 6 can easily drop the paper onto the shaping fixture 17. When the stamping needle 14 is working, the user can adjust the vertical distance between the shaping fixture 17 and the stamping needle 14 according to actual needs.

[0048] In the paper folding machine for easy paper shaping provided in this embodiment of the invention, more specifically, the compaction device includes a driving rubber roller 18, a driven rubber roller 19, a second motor 7, a conveyor belt 20, and a gear set 21. One end of both the driving rubber roller 18 and the driven rubber roller 19 is mechanically connected to the gear set 21. The gear set 21 includes two meshing gears, each mechanically connected to one end of the driving rubber roller 18 and the driven rubber roller 19 respectively. The second motor 7 is driven by the other end of the driving rubber roller 18 via the conveyor belt 20 to achieve opposite rotation of the driving rubber roller 18 and the driven rubber roller 19. It is worth noting that the conveyor belt 20 can be a belt drive. It can also be a chain drive; a pressure gap is provided between the active rubber roller 18 and the driven rubber roller 19. The width of the pressure gap is smaller than the width of the vertical gap 1703 on the shaping fixture 17. At the same time, the pressure gap is aligned with the vertical gap 1703 in the vertical direction. This pressure gap is the closest distance between the edges of the active rubber roller 18 and the driven rubber roller 19. During operation, after the paper is successfully folded by the shaping fixture 17, it falls from the vertical gap 1703 and into the pressure gap between the active rubber roller 18 and the driven rubber roller 19. The active rubber roller 18 and the driven rubber roller 19 rotate towards each other, pressing the two sides of the paper respectively, deepening the paper creases, flattening the paper, and preventing the paper from curling up at the edges.

[0049] In the paper folding machine for easy paper shaping provided in this embodiment of the invention, more specifically, the transfer device further includes a vertical drive cylinder 8, a horizontal drive cylinder 9, a third guide rail 10, and a longitudinal drive cylinder 11. The longitudinal drive cylinder 11 is driven by the vertical drive cylinder 8 through the third guide rail 10. The horizontal drive cylinder 9 is positioned above the vertical drive cylinder 8 and is driven by the vertical drive cylinder 8, thereby realizing the up-and-down movement of the horizontal drive cylinder 9. The horizontal drive cylinder 9 is driven by the suction cup 6. The transfer device realizes the up-and-down, left-and-right, and forward-and-backward movement of the suction cup 6 through the motion control of the horizontal drive cylinder 9, the vertical drive cylinder 8, and the longitudinal drive cylinder 11. The vertical drive cylinder 8 is provided with a slider, which is slidably connected to the third guide rail 10 and moves along the third guide rail 10. The third guide rail 10 is horizontally set, and the longitudinal drive cylinder 11 drives the vertical drive cylinder 8 to move forward and backward in the horizontal direction along the third guide rail 10. The horizontal drive cylinder 9 drives the suction cup 6 to move horizontally, the vertical drive cylinder 8 drives the horizontal drive cylinder 9 to move up and down, and the vertical drive cylinder 11 drives the vertical drive cylinder 8 to move vertically. Therefore, the suction cup 6 can move up and down, left and right, and forward and backward. By adjusting the movement distance of the three drive cylinders in each direction, the position of the suction cup 6 when picking up paper can be adjusted to ensure that each piece of paper is placed in the same position when it is placed in the shaping fixture 17.

[0050] The workflow of the transfer device and shaping device in the paper folding machine for easy paper shaping provided in this embodiment of the invention is as follows: The paper to be folded is placed on the first guide rail 4 by manual or automatic feeding equipment. The moving baffle 2 is locked with the synchronous belt 5. The pressure sensor 201 judges the contact state with the paper to be folded and gives a corresponding signal. The synchronous belt 5 moves, and at the same time, it drives the moving baffle 2 to move to the left. After the horizontal drive cylinder 9 moves forward to the position, the suction cup 6 picks up the paper to be folded and gives a signal. After receiving the signal, the vertical drive cylinder 8 moves upward to the position and gives a signal. The vertical drive cylinder 11 retracts. At this time, the first cylinder 12 moves forward to the position. The paper on the suction cup 6 falls into the shaping fixture 17. The horizontal drive cylinder 9 retracts to the position. The second cylinder 15 moves downward to the position. The punch 14 inserts the paper into the shaping fixture 17. The vertical drive cylinder 11 moves forward to the position. The vertical drive cylinder 8 moves downward to the position and enters the next cycle. The actions of each of the above cylinders are all realized by the external control system through the air circuit for action timing control.

[0051] In the paper folding machine for easy paper shaping provided in this embodiment of the invention, as a further design improvement, the transfer device further includes: a first buffer 26 and a second buffer 27. The first buffer 26 and the second buffer 27 are respectively disposed at both ends of the third guide rail 10 to buffer the movement of the vertical drive cylinder 8 and avoid rigid collisions. It is worth noting that the first buffer 26 and the second buffer 27 are one type of mechanical buffer or hydraulic buffer, and the specific positions of the first buffer 26 and the second buffer 27 relative to the vertical drive cylinder 8 can be adjusted according to user needs and buffer type.

[0052] In the paper folding machine for easy paper shaping provided in this embodiment of the invention, as a further design improvement, a discharge device is also included. The discharge device includes a first discharge port 23 and a second discharge port 24. The first discharge port 23 is located below the compaction device to allow the compressed paper to fall out of the first discharge port 23. The second discharge port 24 is located to the side and below the shaping fixture 17 to allow the air blowing device 16 to blow unshaped defective paper towards the second discharge port 24 and allow it to fall out along the second discharge port 24. The air blowing device 16, located on the base plate 2201, promptly blows away the unfolded paper stuck on the shaping fixture 17, without affecting the continued folding of the next sheet of paper, and completes the screening of defective products.

[0053] The folding machine for easy paper shaping provided in this embodiment of the invention further includes, as a design improvement, an outer shell 25. The outer shell 25 is disposed on the periphery of the folding machine to provide support and protection. The first discharge port 23 and the second discharge port 24 can be exposed through corresponding openings on the outer shell 25, facilitating material discharge. The outer shell 25 is mechanically connected to the base 22 to fix the relative positions of the various devices on the folding machine, while providing corresponding protection for the various devices inside to prevent contamination by dust, oil, etc., and to avoid collisions between the parts of the various devices, thereby improving the safety and reliability of the equipment.

[0054] Compared with the prior art, the paper folding machine provided by the embodiments of the present invention has a reasonable design and a high degree of automation. It overcomes the problems of uneven folding and curling edges of existing paper folding machines. The paper is stably folded and the creases are deepened, making it easy to shape the paper. It is suitable for automated mass production and meets the specific needs of users.
