Description

Technical Field

[0001] This invention relates to the field of packaging equipment, and in particular to a paper receiving and turning device. Background Technology

[0002] Due to the uneven force between the face paper and the inner paper, paper bending is inevitable. Bending paper is very likely to produce defective products when it is made on equipment such as gluing boxes or die-cutting. Therefore, the problem of paper bending must be addressed in the papermaking process. The usual method is to stack stacks of paper in the direction of bending, alternating between the front and back, and rely on the weight of the paper itself to press the paperboard flat and stabilize it naturally. Flipping stacks of paper is essential during the stacking process. The current method involves rotating the paper stacks one after another on the paper conveyor line by swinging the take-up arm 180 degrees back and forth. While this method achieves the flipping of the paper, its reciprocating structure means that the next paper feeding operation can only begin after both the feeding and output steps are completed. This results in a long work cycle and significantly restricts the working speed. Furthermore, due to its inherent structural limitations, the speed and frequency of the reciprocating swing structure are inherently low, leading to structural inefficiencies and low production efficiency. Additionally, due to the influence of other machine components, the longitudinal and transverse baffles inside the take-up arm can only be fixed and cannot be adjusted according to paper specifications. When the paper specifications are not compatible, slippage or even jamming may occur between the paperboards during the flipping process. After flipping, the paper may be uneven, making automatic stacking difficult. This results in structural inefficiencies and unstable operation.

[0003] Therefore, existing flipping devices have long flipping cycles and low production efficiency. At the same time, due to the influence of other components, the baffle of the paper receiving device can only be designed as a fixed type, which has poor adaptability to the specifications and dimensions of the paperboard. In fact, when the paperboard specifications do not match, flipping may cause the paper to slip or get stuck, resulting in the paperboard being uneven after flipping, which affects the further processing of the paperboard. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, such as long flipping cycle, low production efficiency, and poor adaptability due to unreasonable structure, and to provide a paper collection flipping device.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A paper receiving and flipping device includes a flipping mechanism, characterized in that the flipping mechanism includes a rotating frame main shaft, paper receiving components, and a flipping frame supporting the entire flipping mechanism, wherein the number of paper receiving components is at least two, and each paper receiving component is symmetrically arranged on both sides of the rotating frame main shaft, and the flipping frame is driven by the rotation of the rotating frame main shaft.

[0007] Furthermore, the paper receiving and turning device also includes an auxiliary turning mechanism, which includes a tray, a sprocket assembly, a first chain, a tray drive shaft, a second chain, and a tray drive motor. The first chain is connected to the sprocket assembly, and the tray drive shaft passes through the turning frame and is connected to the sprocket assembly. There are at least two first chains. The two ends of the tray are respectively fixed on the corresponding first chains. The tray drive motor is fixed to the outer body of the machine and drives the sprocket assembly through the second chain.

[0008] Furthermore, the sprocket assembly includes a transmission sprocket, a first sprocket, a second sprocket, a third sprocket, a fourth sprocket, and a drive sprocket;

[0009] The transmission sprocket, the first sprocket, the second sprocket and the fourth sprocket are rotatably connected to the inside of the tilting frame in sequence. The third sprocket is sleeved on the main shaft of the rotating frame. The drive sprocket is connected to the transmission sprocket through the support plate drive shaft. The third sprocket and the drive sprocket are both located on the outside of the tilting frame.

[0010] The third sprocket is connected to the motor sprocket and the drive sprocket via the second chain. The motor sprocket is fixed to the extension end of the output shaft of the drive motor. The transmission sprocket, the first sprocket, the second sprocket and the fourth sprocket are connected via the first chain.

[0011] Furthermore, the number of tray plates is at least two, each tray plate is continuously fixed on the chain, and there is a gap between adjacent tray plates. The size of the gap is in the range of 1-10mm, and the total width of all fixed tray plates is less than or equal to the distance between the axis of the first sprocket and the axis of the second sprocket.

[0012] Furthermore, the flipping frame includes a first rotating frame side plate and a second rotating frame side plate, the rotating frame main shaft passes through the first rotating frame side plate and the second rotating frame side plate, the first rotating frame side plate and the second rotating frame side plate are fixedly connected to the rotating frame main shaft, one end of the paper receiving component is fixedly connected to the first rotating frame side plate, and the other end is fixedly connected to the second rotating frame side plate.

[0013] Furthermore, the paper receiving component includes a paper receiving plate, a first guide plate, a second guide plate, and a third guide plate. One end of the paper receiving plate is fixedly connected to a first rotating frame side plate, and the other end is fixedly connected to a second rotating frame side plate. The first guide plate, the second guide plate, and the third guide plate are all slidably connected to the paper receiving plate. The end faces of the first guide plate and the second guide plate are perpendicular to the axis of the rotating frame main shaft, and the end face of the third guide plate is parallel to the axis of the rotating frame main shaft.

[0014] Furthermore, the paper receiving plate is provided with a slide rail, and the first, second, and third guide plates are fixed with sliders corresponding to the slide rail. The first, second, and third guide plates are slidably connected to the slide rail on the paper receiving plate through the sliders.

[0015] Furthermore, adjusting nuts are fixed on the first, second, and third paper guides.

[0018] Compared with the prior art, the present invention has the following advantages:

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0027] Example 1

[0028] like Figure 1 As shown, a paper receiving and turning device includes a turning mechanism, which includes a rotating frame main shaft 15, paper receiving components 20, and a turning frame supporting the entire turning mechanism. The number of paper receiving components 20 is at least two, and each paper receiving component 20 is symmetrically arranged on both sides of the rotating frame main shaft 15. The turning frame is driven by the rotation of the rotating frame main shaft 15.

[0029] Working principle: First, the cardboard 2 is conveyed to the receiving component 20 by external equipment to complete the receiving of the cardboard 2; the external drive device drives the rotating frame main shaft 15 to rotate the flipping frame 180° to complete the flipping of the cardboard 2; as the flipped cardboard 2 falls to the lower station, the cardboard conveying mechanism conveys the cardboard 2 to be flipped to another set of receiving components 20 on the flipping device, and then the cardboard 2 is flipped again, and so on.

[0030] This solution sets up two sets of paper receiving components (more than 20 units) so that the paperboard is placed below the entire flipping device while being received above. This avoids the disadvantage of existing flipping devices that require flipping again before receiving the paperboard, and has the advantages of short work order cycle and high work efficiency.

[0031] The paper receiving and turning device also includes an auxiliary turning mechanism, which includes a tray 5, a sprocket assembly, a first chain 7, a tray drive shaft 12, a second chain 21, and a tray drive motor 9. The first chain 7 is connected to the sprocket assembly, and the tray drive shaft 12 passes through the turning frame and is connected to the sprocket assembly. There are at least two first chains 7. The two ends of the tray 5 are respectively fixed on the corresponding first chains 7. The tray drive motor 9 is fixed to the outer body of the machine and drives the sprocket assembly through the second chain 21.

[0032] Working principle: Before or slightly after the paper receiving component 20 receives the paperboard 2, the paper tray 5 is moved above the paper receiving component 20 by rotating the first chain 7. The external drive device causes the main shaft 15 of the rotating frame to drive the flipping mechanism and the auxiliary flipping mechanism to rotate 180°. During this process, the paperboard 2 naturally flips above the paper tray 5 under the action of gravity, and the paper tray 5 supports the paperboard 2.

[0033] The tray drive motor 9 drives the sprocket assembly via the second chain 21. Both ends of the tray drive shaft 12 are connected to sprockets. The sprocket assembly drives the first chain 7. The tray 5 moves under the action of the first chain 7 at both ends. Here, the rotation direction of the first chain 7 is opposite to the flipping direction of the flipping device. As the first chain 7 rotates, a tray 5 with a surface perpendicular to the surface of the tray 2 appears among the multiple trays 5, preventing the tray 2 from rotating with the tray. When the tray 5 is pulled away from under the tray 2, the tray 2 naturally falls into the lower station, assisting the tray 2 in completing the flipping operation. Then, driven by the first chain 7, the tray 5 moves to the top of the upper paper receiving component for the next flipping operation of the tray 2.

[0034] This solution uses a tray 5 and its driving mechanism to assist in the flipping of the cardboard 2. The tray 5 moves around the main shaft 15 of the rotating frame to support and flip the cardboard 2, avoiding the swinging flipping mode of the cardboard in the prior art. The structure is simple and ingenious. At the same time, the rotation direction of the first chain 7 is opposite to the flipping direction of the flipping device, so that the process of resetting the tray 5 will not affect the paper receiving component 20 to receive the cardboard, improving the continuity of operation and further improving the flipping efficiency of the cardboard.

[0035] The sprocket assembly includes a transmission sprocket 1, a first sprocket 4, a second sprocket 6, a third sprocket 10, a motor sprocket 14, a fourth sprocket 18, and a drive sprocket 11;

[0036] The transmission sprocket 1, the first sprocket 4, the second sprocket 6 and the fourth sprocket 18 are rotatably fixed on the inner side of the tilting frame in sequence. The third sprocket 10 is sleeved on the main shaft 15 of the rotating frame. The drive sprocket 11 is connected to the transmission sprocket 1 through the support plate drive shaft 12. The third sprocket 10 and the drive sprocket 11 are both located on the outer side of the tilting frame.

[0037] The third sprocket 10 is connected to the motor sprocket 14 and the drive sprocket 11 respectively via the second chain 21. The motor sprocket 14 is fixed to the extension end of the output shaft of the drive motor 9. The transmission sprocket 1, the first sprocket 4, the second sprocket 6 and the fourth sprocket 18 are connected via the first chain 7.

[0038] Working principle: The tray board drive motor 9 drives the third gear 10 through the motor sprocket 14. The third gear 10 drives the drive sprocket 11 to rotate through the second chain 21. The drive sprocket 11 drives the transmission sprocket 1 to rotate through the tray drive shaft 12. The transmission sprocket 1 drives the first sprocket 4, the second sprocket 6 and the fourth sprocket 18 to rotate through the first chain 7. At the same time, the first chain 7 drives the tray board 5 to rotate around the main shaft 15 of the rotating frame.

[0039] This solution ensures that the cardboard 2 is subjected to uniform force during the removal of the cardboard 5 by setting up a cardboard drive motor 9 to drive the sprocket assembly and by using the cardboard drive shaft 12 to ensure the synchronicity of the movement of the first chain 7 at both ends of the cardboard 5. This avoids the problem of uneven force on the cardboard 2 causing wrinkles.

[0040] There are at least two trays 5, each tray 5 is continuously fixed on the first chain 7, and there is a gap between adjacent trays 5. The size of the gap is in the range of 1-10mm. The total width of all fixed trays 5 is less than or equal to the distance between the axis of the first sprocket 4 and the axis of the second sprocket 6.

[0041] The flipping frame includes a first flipping frame side plate 16 and a second flipping frame side plate 17. The main shaft 15 of the flipping frame passes through the first flipping frame side plate 16 and the second flipping frame side plate 17. The first flipping frame side plate 16 and the second flipping frame side plate 17 are fixedly connected to the main shaft 15 of the flipping frame. One end of the paper receiving component 20 is fixedly connected to the first flipping frame side plate 16, and the other end is fixedly connected to the second flipping frame side plate 17.

[0042] The paper receiving component 20 includes a paper receiving plate 19, a first guide plate 3, a second guide plate 13, and a third guide plate 8. One end of the paper receiving plate 19 is fixedly connected to a first rotating frame side plate 16, and the other end is fixedly connected to a second rotating frame side plate 17. The first guide plate 3, the second guide plate 13, and the third guide plate 8 are all slidably connected to the paper receiving plate 19. The end faces of the first guide plate 3 and the second guide plate 13 are perpendicular to the axis of the rotating frame main shaft 15, and the end face of the third guide plate 8 is parallel to the axis of the rotating frame main shaft 15.

[0043] The paper receiving plate 19 is equipped with a slide rail. The first plate 3, the second plate 13 and the third plate 8 are fixed with sliders corresponding to the slide rail. The first plate 3, the second plate 13 and the third plate 8 are slidably connected to the slide rail on the paper receiving plate 19 through the sliders.

[0044] Adjusting nuts are fixed on the first platen 3, the second platen 13, and the third platen 8. The adjusting nut on the first platen 3 is threadedly connected to the screw on the second rotating frame side plate 17; the adjusting nut on the second platen 13 is threadedly connected to the screw on the first rotating frame side plate 16; and the adjusting nut on the third platen 8 is threadedly connected to the screw on the paper receiving plate 19.

[0045] Working principle: The paper receiving component 20, consisting of the paper receiving plate 19, the first guide plate 3, the second guide plate 13, and the third guide plate 8, can fix the paperboard 2 with 4 degrees of freedom. With the support plate 5 above the paper receiving component 20, it can fix the paperboard 2 with 5 degrees of freedom. The first guide plate 3, the second guide plate 13, and the third guide plate 8 are all connected with threaded screw structures, which can adjust the left and right positions of the first guide plate 3 and the second guide plate 13, and the front and back positions of the third guide plate 8, thereby adjusting the size of the paperboard 2 to fix it.

[0046] This solution fixes the cardboard 2 with 5 degrees of freedom, ensuring that the cardboard 2 remains neat during the flipping process, with excellent fixing effect. At the same time, the adjustable baffle allows the device to flip cardboard of various sizes, optimizing the adaptability of the device.

[0047] There is a gap between the upper surface of the third cardboard 8 and the surface of the support cardboard 5, with the gap size ranging from 0.5 to 4 mm.

[0048] The gap between the upper surface of the third cardboard 8 and the surface of the support cardboard 5 should not exceed the thickness of a single cardboard sheet. This is to prevent cardboard from sliding out through the gap between the third cardboard 8 and the support cardboard 5 during the process of the support cardboard 5 being pulled out from under the cardboard 2 after the cardboard 2 is flipped over.

[0049] The outer side of the first chain 7 is also equipped with baffles, and there are multiple baffles.

[0050] Work process:

[0051] 1) such as Figure 1 As shown, before the paper receiving component 20 receives the paperboard 2, the left and right positions of the first paperboard 3 and the second paperboard 13 and the front and back positions of the third paperboard 8 are adjusted by the screw and nut mechanism so that the paper receiving component 20 can receive the paperboard 2 to be flipped. The paperboard support 5 is located above the paper receiving component 20, and the external device conveys the paperboard 2 to the paper receiving component 20.

[0052] 2) such as Figure 2 As shown, after the receiving component 20 receives the paper, the external device drives the rotating frame main shaft 15 to rotate, causing the flipping device and the cardboard 2 to rotate 180° around the rotating frame main shaft 15. Under its own gravity, the cardboard 2 naturally falls above the cardboard support 5, and the surface of the cardboard 2 remains parallel to the plane of the receiving cardboard 2 below. The cardboard support drive motor 9 is turned on to drive the first chain 7 to rotate. The first chain 7 drives both ends of the cardboard support 5 to move together, and the cardboard support 5 is pulled away from below the cardboard 2. The cardboard 2 remains stationary under the action of the third cardboard support 8. After the cardboard support 5 is pulled away, the cardboard 2 falls onto the receiving device below, completing the flipping.

[0053] 3) such as Figure 3As shown, while the paper receiving component below places the cardboard 2 onto the receiving device below, the paper receiving component above receives the cardboard. After the cardboard below completes its flipping, the paperboard support 5, under the action of the paperboard support drive motor 9 and the sprocket assembly, is driven by the first chain 7 to move above another set of paper receiving components 20. At the same time, the cardboard 2 enters the paper receiving component 20 located above the flipping device for the next flipping, and so on in a continuous cycle.

[0054] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
