Description

Technical Field

[0001] This invention relates to the field of household paper production technology, and in particular to a household paper stacking, folding, and conveying device. Background Technology

[0002] The production of household paper products such as facial tissues, boxed tissues, and toilet paper involves processes including rewinding, stacking, cutting, and packaging. In current production processes, after rewinding and stacking, the paper needs to be separated and transported to the cutting station for further processing. The existing stacking process is primarily accomplished using stacking needles. Because the paper is tightly stacked with very little gap between adjacent stacks, traditional stacking needles often tear the paper during insertion, resulting in low stacking accuracy and fluctuations in the number of sheets per stack.

[0003] In addition, after the paper is stacked, it needs to be transferred to a conveyor belt for transport. During the transport process, because the conveyor belt runs at a high speed and the paper is relatively thin, the airflow generated during transport can easily blow up the top layer of paper, affecting subsequent cutting and packaging. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention discloses a paper-folding, paper-folding and conveying device for household paper, including a frame, a folding mechanism, a gripping mechanism and a paper-folding mechanism. The folding mechanism is mounted on the frame via a first crossbeam, and a receiving plate is provided below the folding mechanism. The gripping mechanism is mounted on one side of the folding mechanism via a longitudinal sliding unit, and the paper-folding mechanism is mounted on one side of the receiving plate.

[0005] Furthermore, the stacking mechanism includes a stacking unit, a first stacking needle, a second stacking needle, and an air blowing pipe. The first and second stacking needles are both connected to the stacking unit in a transmission manner, and the air blowing pipe is disposed on one side of the stacking unit.

[0006] Furthermore, a lifting unit is provided on one side of the stacking unit, and the stacking unit is connected to the lifting unit through a first connecting plate.

[0007] Furthermore, the air blowing pipe is mounted on the first crossbeam via a telescopic unit, and the telescopic unit is provided with a second connecting plate, on which the air blowing pipe is mounted.

[0008] Furthermore, the gripping mechanism includes a horizontal sliding unit and multiple gripping components. The horizontal sliding unit is slidably connected to the vertical sliding unit on both sides, and the multiple gripping components are slidably disposed on the horizontal sliding unit.

[0009] Furthermore, the gripping assembly includes a fixed bracket, a longitudinal drive unit, and a gripping drive unit. The longitudinal drive unit is mounted on the transverse sliding unit via the fixed bracket, and the gripping drive unit is located below the longitudinal drive unit. The longitudinal drive unit is connected to a first clamping plate, and the gripping drive unit is connected to a second clamping plate.

[0010] Furthermore, the folding tail mechanism includes a third crossbeam, a first flipping frame, a second flipping frame, a first flipping drive unit, and a second flipping drive unit. The first flipping frame and the second flipping frame are both disposed on one side of the third crossbeam. The first flipping drive unit is disposed on one side of the first flipping frame and the two are connected in a transmission manner. The second flipping drive unit is disposed on one side of the second flipping frame and the two are connected in a transmission manner.

[0011] Furthermore, the first flipping frame is provided with a plurality of first flipping blocks at intervals, and the second flipping frame is provided with a plurality of second flipping blocks at intervals, and the first flipping blocks and the second flipping blocks are arranged alternately.

[0012] Furthermore, the two ends of the third crossbeam are rotatably connected to the frame, and a third tilting drive unit is provided below the third crossbeam, which is connected to the third crossbeam in a transmission manner.

[0013] Furthermore, a conveyor belt is provided on the outer side of the frame near the folding tail mechanism.

[0015] The paper stacking, folding, and conveying device of the present invention can accurately and efficiently stack paper through the stacking mechanism, ensuring that the paper will not be torn. The gripping mechanism grips the stacked paper to the folding mechanism, which folds the paper tail to prevent the paper from being blown up during the conveying process, thus ensuring normal cutting and packaging in the future.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0040] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0041] In the description of the embodiments, unless otherwise explicitly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] like Figure 1 As shown, the tissue paper stacking, folding, and conveying device of this embodiment includes a frame 10, a stacking mechanism 20, a gripping mechanism 30, and a folding mechanism 40. The stacking mechanism 20 is mounted on the frame 10 via a first crossbeam 50. A receiving plate 60 is provided below the stacking mechanism 20, which is used to support the paper stacks conveyed by the rewinder. The gripping mechanism 30 is mounted on one side of the stacking mechanism 20 via a longitudinal sliding unit 70, and the folding mechanism 40 is mounted on one side of the receiving plate 60.

[0043] A conveyor belt 80 is provided on the outer side of the frame 10 near the paper folding tail mechanism 40. The conveyor belt 80 is connected to the cutting equipment and directly transports the paper stack after paper folding tail to the cutting equipment. An electrical control cabinet 90 for controlling the overall operation of the machine is also provided on the side of the frame 10.

[0044] like Figure 2-3 As shown, the stacking mechanism 20 includes a stacking unit 21, a first stacking pin 22, a second stacking pin 23, and an air blowing pipe 24. The stacking unit 21 is connected to a drive rod 211. The drive rod 211 has racks 212 on both sides. The racks 212 have a first transmission gear block 213 and a second transmission gear block 214 meshing on both sides respectively. The top of the first stacking pin 22 is connected to the first transmission gear block 213, and the top of the second stacking pin 23 is connected to the second transmission gear block 214. When the stacking unit 21 drives the drive rod 211 to move up and down, the opening and closing action of the first stacking pin 22 and the second stacking pin 23 can be realized.

[0045] A lifting unit 25 is provided on one side of the stacking unit 21, and the stacking unit 21 is connected to the lifting unit 25 through a first connecting plate 26. The lifting unit 25 drives the stacking unit 21 to move up and down, thereby inserting the first stacking needle 22 and the second stacking needle 23 into the stack of paper to be stacked.

[0046] The air blowing pipe 24 is mounted on the first crossbeam 50 via a telescopic unit 27. The telescopic unit 27 is equipped with a second connecting plate 28, and the air blowing pipe 24 is mounted on the second connecting plate 28. The air inlet at the upper end of the air blowing pipe 24 is connected to an air source, and the air outlet at the lower end is aligned with the paper stack.

[0047] like Figure 4-5 As shown, during air blowing, high-pressure gas is blown out from the outlet of the air blowing pipe 24, creating a gap in the paper stack. The lifting unit 25 drives the first separating needle 22 and the second separating needle 23 to insert into this gap. At the same time, the separating unit 21 drives the first separating needle 22 and the second separating needle 23 to open outward, separating the two adjacent stacks of paper, thus completing the separating operation. Since the first separating needle 22 and the second separating needle 23 are inserted along the blown-open gap, the problem of the separating needles directly inserting into the paper and causing paper damage can be effectively avoided. Furthermore, the separating accuracy is significantly improved compared to traditional separating methods.

[0048] like Figure 6-7 As shown, the gripping mechanism 30 includes a horizontal sliding unit 31 and a plurality of gripping components 32. The two sides of the horizontal sliding unit 31 are slidably connected to the vertical sliding unit 70, and the plurality of gripping components 32 are slidably disposed on the horizontal sliding unit 31.

[0049] The gripping assembly 32 includes a fixed bracket 321, a longitudinal drive unit 322, and a gripping drive unit 323. The longitudinal drive unit 322 is mounted on the transverse sliding unit 31 via the fixed bracket 321. The gripping drive unit 323 is mounted below the longitudinal drive unit 322. The longitudinal drive unit 322 is connected to a first clamping plate 324, and the gripping drive unit 323 is connected to a second clamping plate 325.

[0050] The gripping drive unit 323 is connected to a drive rack 326, and a transmission gear 327 is connected to one side of the second clamping plate 325. The drive rack 326 meshes with the transmission gear 327.

[0051] The fixed bracket 321 is connected to the slider via a guide rail and a movable bracket 328. The gripping drive unit 323 is mounted on the movable bracket 328. In the initial state, the second clamping plate 325 is nearly horizontal. When gripping the paper stack, the longitudinal drive unit 322 drives the movable bracket 328 to move downward as a whole, so that the first clamping plate 324 and the second clamping plate 325 are respectively located on both sides of the stacked paper stack. The gripping drive unit 323 pushes the drive rack 326 to move backward, and the transmission gear 327 rotates clockwise, causing the second clamping plate 325 to flip toward the side of the first clamping plate 324, so that the second clamping plate 325 becomes vertical, thereby clamping the paper stack through the cooperation of the first clamping plate 324 and the second clamping plate 325.

[0052] Subsequently, the longitudinal drive unit 322 drives the transverse sliding unit 31 to move towards the folding tail mechanism 40 and places the paper stack on the folding tail station to perform the paper tail folding process.

[0053] like Figure 8-11 As shown, the paper folding tail mechanism 40 includes a third crossbeam 41, a first flipping frame 42, a second flipping frame 43, a first flipping drive unit 44, and a second flipping drive unit 45. The first flipping frame 42 and the second flipping frame 43 are both disposed on one side of the third crossbeam 41. The first flipping drive unit 44 is disposed on one side of the first flipping frame 42 and the two are connected in a transmission manner. The second flipping drive unit 45 is disposed on one side of the second flipping frame 43 and the two are connected in a transmission manner.

[0054] The first flipping frame 42 is provided with a plurality of first flipping blocks 46 spaced apart, and the second flipping frame 43 is provided with a plurality of second flipping blocks 47 spaced apart. The first flipping blocks 46 and the second flipping blocks 47 are staggered to prevent interference between them during flipping.

[0055] The third crossbeam 41 is rotatably connected to the frame 10 at both ends. A third tilting drive unit 48 is provided below the third crossbeam 41, and the third tilting drive unit 48 is connected to the third crossbeam 41 in a transmission manner.

[0056] The third crossbeam 41 is provided with multiple horizontal trays 411 at intervals for supporting paper products. Multiple vertical baffles 412 are also provided at intervals on one side of the third crossbeam 41 to prevent paper products from falling off from one side. The vertical baffles 412 are connected to a baffle drive unit 413 located below the third crossbeam 41, and the baffle drive unit 413 can drive the vertical baffles 412 to rise and fall.

[0057] The gripping mechanism 30 places the paper stack on the horizontal pallet 411. The first flipping drive unit 44 drives the first flipping frame 42 to rotate, thereby causing the first flipping block 46 to flip inward, achieving the first fold of the paper tail (e.g., Figure 9 (As shown).

[0058] The second flipping drive unit 45 drives the second flipping frame 43 to rotate, thereby causing the second flipping block 47 to flip inward, realizing the second fold of the paper tail (e.g. Figure 10 (As shown).

[0059] After the paper tail is folded, the third flipping drive unit 48 drives the third crossbeam 41 to flip, flipping the paper stack onto the conveyor belt 80 and conveying it to the cutting equipment for the cutting process.

[0060] like Figure 11 As shown, the piston rod of the third flipping drive unit 48 is slidably and rotatably connected to the slide rail 49, and the third crossbeam 41 is connected to the upper end of the slide rail 49. When the piston rod of the third flipping drive unit 48 extends, it drives the slide rail 49 to deflect, thereby driving the third crossbeam 41 to rotate, causing the horizontal pallet 411 to flip outward, flipping the paper stack above it onto the conveyor belt 80, and then conveying it to the cutting equipment.

[0061] By folding twice, the paper tail is folded into two layers, increasing the thickness and weight of the paper tail section. During high-speed conveying, the paper tail will not be blown up by the airflow, improving the paper tail folding efficiency and ensuring normal subsequent cutting and packaging.

[0062] It should be noted that each of the transverse drive units and longitudinal drive units in this embodiment adopts a linear drive method commonly used in the art, such as a linear module, a cylinder or hydraulic cylinder, a lead screw and nut transmission method, etc.; each drive unit adopts conventional technical means in the art such as a cylinder, hydraulic cylinder or linear stepper motor.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by the present invention.
