Abstract
Description
Technical Field
[0001] This utility model relates to the field of tissue paper stacking technology, and in particular to a tissue paper stacking device. Background Technology
[0002] In the field of tissue paper production and packaging, tissue paper stacking devices are key equipment for achieving orderly tissue paper sorting and facilitating subsequent packaging and use. The rationality of the stacking structure and the level of automation directly affect the user experience and production efficiency of tissue paper.
[0003] Most tissue paper stacking devices currently on the market use a single support component or a simple stacking design, with tissues mostly stacked in parallel during the stacking process. This type of stacking structure has obvious limitations: when pulling out the current tissue, because there is no effective interlocking relationship between the tissues, it is impossible to automatically pull out a segment of the next tissue through friction. Users need to manually pull out each tissue one by one, which is cumbersome and impractical, especially in commercial settings (such as public restrooms and restaurants) or high-frequency usage scenarios.
[0004] Meanwhile, the supporting components of existing devices are mostly fixed installation structures, and the spacing cannot be flexibly adjusted. However, there are various sizes of tissue paper produced (such as small handkerchiefs, medium-sized facial tissues, and large-sized hand towels). When it is necessary to switch between folding different sizes of tissue paper, it is necessary to disassemble and replace special supporting components or adjust the entire machine structure. The operation steps are cumbersome and time-consuming, which not only increases the equipment adaptation cost but also causes production downtime, seriously affecting the continuity and efficiency of folding operations, and making it difficult to meet the diverse tissue paper folding needs.
[0005] In summary, the shortcomings of existing tissue paper stacking devices in terms of the practicality of the stacking structure and the flexibility of size adaptation have become key issues restricting the convenience of tissue paper use and the improvement of production efficiency. There is an urgent need for a stacking device that can achieve precise interlocking and nesting of tissue paper and can flexibly adapt to tissue paper of different sizes. Utility Model Content
[0006] In order to overcome the technical problems mentioned in the background art, the present invention provides a tissue paper stacking device.
[0007] A tissue paper stacking device includes a support frame, conveyor wheels, rotating shafts, support brackets, sliding blocks, a swinging assembly, an adjusting assembly, and a collecting assembly. Two support frames are provided, symmetrically arranged and spaced apart. Two conveyor wheels are rotatably connected between the upper sides of the two support frames, with a gap reserved between the two conveyor wheels for tissue paper conveying. Slide grooves are provided on the front and rear sides of the middle of each support frame. A rotating shaft is slidably connected between the two slide grooves on the front side and between the two slide grooves on the rear side. Sliding blocks are fixedly connected to both ends of the rotating shaft, forming a sliding fit with the corresponding slide groove. Support brackets are fixedly connected to the inner surfaces of both the front and rear rotating shafts, and the two support brackets are arranged opposite each other directly below the conveyor wheels. An adjusting assembly is provided on the outer side of the support frame, a swinging assembly is provided on the sliding block, and a collecting assembly is provided on the lower side of the support frame.
[0008] Furthermore, the support surface of the support frame has an arc-shaped structure.
[0009] Furthermore, the outer circumference of the conveyor wheel is covered with a silicone layer.
[0010] Furthermore, the swing assembly includes a rocker arm, a first motor, a rotating disk, and a protrusion. Both ends of the rotating shaft penetrate the outer side wall of the corresponding side sliding block and are fixedly connected to the rocker arm. The inner end of the rocker arm has a movable groove. The first motor is installed on the outer side of the sliding block. The rotating disk is connected to the output shaft of the first motor. A protrusion is fixedly connected to the eccentric position of the rotating disk. The protrusion is embedded in the movable groove of the corresponding side rocker arm and forms a sliding fit.
[0011] Furthermore, the collection component includes an electric slide rail, a slider, and a collection frame. Electric slide rails are installed on the lower part of the inner sidewalls of the two support frames. The two electric slide rails are arranged symmetrically. A slider is slidably connected to each electric slide rail. A collection frame is fixedly connected between the two sliders. The collection frame is horizontally positioned directly below the two support frames.
[0012] Furthermore, the adjustment assembly includes a movable frame, a support frame, a second motor, a screw, and a lifting frame. A second motor is installed on the outer wall of each of the two support frames. A screw is connected to the output shaft of the second motor, and a lifting frame is threaded onto the screw. A support frame is fixedly connected to the support frame directly below the screw. The bottom end of the screw is rotatably connected to the support frame via a bearing. Movable frames are rotatably connected to both ends of the support frame via pins. A long sliding groove is formed in the middle of the movable frame along its length. The long sliding grooves of the two movable frames on corresponding sides are slidably engaged with the connecting shafts at both ends of the lifting frame. A short sliding groove is formed at the upper end of the movable frame along its length, and a sliding block is slidably engaged with the short sliding groove of the corresponding movable frame.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. Two first motors controlled by phase difference drive the support frame to move alternately, accurately folding the continuously fed paper towels into a zigzag structure with staggered ends and nested together. This structure allows the next paper towel to be automatically pulled out by friction when the current paper towel is taken out, providing convenience for continuous use and greatly improving the practicality and automation level of the folding.
[0015] 2. The adjustment component drives the screw via a second motor, which in turn drives the lifting frame and the movable frame to precisely control the position of the sliding block in the slide groove, thereby flexibly adjusting the distance between the front and rear support frames. This design allows a single device to quickly adapt to the production of various sizes and specifications of paper towels, enhancing the versatility and utilization of the equipment.

Detailed Implementation
[0022] like Figures 1-5As shown, a tissue paper stacking device includes a support frame 1, conveyor wheels 2, a rotating shaft 3, a support bracket 4, a sliding block 5, a swing assembly, an adjustment assembly, and a collection assembly. Two support frames 1 are provided, arranged symmetrically and spaced apart. Two conveyor wheels 2 are rotatably connected between the upper sides of the two support frames 1 via bearings. The two conveyor wheels 2 are spaced apart in a horizontal direction, with a gap reserved between them for tissue paper conveying. The conveyor wheels 2 are driven by an external power source to achieve uniform and continuous tissue paper conveying. The outer circumference of the conveyor wheels 2 is covered with a silicone layer to prevent slippage during tissue paper conveying and to buffer the contact pressure between the conveyor wheels 2 and the tissue paper, preventing scratches on the edges of the tissue paper. Sliding grooves are provided on the front and rear sides of the middle of the two support frames 1, allowing sliding between the two grooves on the front side and between the two grooves on the rear side. A rotating shaft 3 is connected to the support frame 2. Sliding blocks 5 are fixedly connected to both ends of the rotating shaft 3. The sliding blocks 5 form a sliding fit with the corresponding sliding grooves. Support frames 4 are fixedly connected to the inner sides of the front and rear rotating shafts 3. The two support frames 4 are arranged opposite each other and are located directly below the conveyor wheel 2. They are used to support and stack the paper towels during the conveying process. The support surface of the support frame 4 has an arc-shaped structure, which can increase the contact area with the paper towels, making the paper towels more stable and reducing paper towel wrinkles caused by local stress. An adjustment component is provided on the outside of the support frame 1 to adjust the distance between the front and rear support frames 4 to accommodate paper towels of different sizes. A swing component is provided on the sliding block 5 to drive the support frame 4 to swing back and forth to achieve paper towel stacking. A collection component is provided on the lower side of the support frame 1 to receive the stacked paper towels and adapt to changes in stacking height.
[0023] like Figures 1-3 As shown, the swing assembly includes a rocker arm 6, a first motor 7, a rotating disk 8, and a protrusion 9. Both ends of the rotating shaft 3 pass through the outer side wall of the corresponding side sliding block 5 and are fixedly connected to the rocker arm 6. The inner end of the rocker arm 6 has a movable groove. The first motor 7 is bolted to the outer side of the sliding block 5. The rotating disk 8 is connected to the output shaft of the first motor 7. A protrusion 9 is welded to the eccentric position of the rotating disk 8. The protrusion 9 is embedded in the movable groove of the corresponding side rocker arm 6 and forms a sliding fit. The protrusion 9 can slide along the length of the movable groove to convert the rotational motion of the rotating disk 8 into the reciprocating swing motion of the rocker arm 6.
[0024] like Figure 5 As shown, the collection assembly includes an electric slide rail 16, a slider 17, and a collection frame 18. The lower part of the inner sidewall of each of the two support frames 1 is screwed with an electric slide rail 16. The two electric slide rails 16 are arranged symmetrically from left to right. A slider 17 is slidably connected to each electric slide rail 16. The collection frame 18 is connected between the two sliders 17 by bolts. The collection frame 18 is horizontally set directly below the two support frames 4 to receive the paper towels after they have been stacked by the support frames 4. The electric slide rail 16 can drive the slider 17 to move the collection frame 18 downward at a uniform speed in the vertical direction, dynamically adapting to changes in the stacking height of the paper towels.
[0025] When folding tissues, two first motors 7 are activated and operate with a phase difference. The output shafts of the first motors 7 drive the rotating disk 8 and the protrusion 9 to rotate synchronously. The protrusion 9, through its sliding engagement with the movable groove of the rocker arm 6, drives the rocker arm 6 to swing back and forth around the axis of the rotating shaft 3, thereby driving the rotating shaft 3 and the support frame 4 to swing back and forth synchronously. Due to the phase difference between the two first motors 7, the swing directions of the front and rear support frames 4 are alternately opposite. The cut single tissues are continuously fed into the gap between the two conveyor wheels 2 by the upstream mechanism. When the front support frame 4 swings to the pressing position, it presses and positions the tail section (or lower half) of the falling tissue in the collection frame 18. At the same time, the first section (or upper half) of the tissue is still... Driven by the conveyor wheel 2, the paper towels continue to move downwards. Then, the rear support frame 4 swings to the lifting position. Its function is not to press, but to support and guide the first section of the paper towel that falls next (or the upper half of the next paper towel), so that it accurately covers the paper layer that was pressed down last time. This cycle is repeated. Through the high-frequency, alternating, and opposite swinging motion of the front and rear support frames 4, the continuously input paper towels automatically form a zigzag folding structure with alternating ends and nested to each other during the stacking process. As the amount of paper towels stacked increases, the electric slide rail 16 drives the slider 17 to move the collection frame 18 downwards at a uniform speed in the vertical direction, dynamically adapting to changes in stacking height. Moreover, the lateral length of the conveyor wheel 2 can be adapted to the simultaneous operation of multiple sets of paper towels, realizing the simultaneous stacking of multiple sets of paper towels and improving work efficiency.
[0026] like Figure 1 and Figure 4 As shown, the adjustment assembly includes a movable frame 11, a support frame 12, a second motor 13, a screw 14, and a lifting frame 15. The second motor 13 is bolted to the outer walls of both support frames 1. The output shaft of the second motor 13 is connected to the screw 14, and the lifting frame 15 is threaded onto the screw 14. The lifting frame 15 maintains a sliding fit clearance with the outer walls of the support frames 1 to ensure that the lifting frame 15 can move smoothly in the vertical direction. The support frame 12 is bolted to the support frame 1 at a position directly below the screw 14. The bottom end of the screw 14 is rotatably connected to the support frame 12 through a bearing. The front and rear ends of the support frame 12 are rotatably connected to the movable frame 11 through axle pins. The middle part of the movable frame 11 has a long sliding groove along its length. The long sliding grooves of the two movable frames 11 on the corresponding sides are slidably fitted with the connecting shafts at the front and rear ends of the lifting frame 15, respectively. The upper end of the movable frame 11 has a short sliding groove along its length. The sliding block 5 is slidably fitted with the short sliding groove of the corresponding movable frame 11.
[0027] When adjusting the distance between the two support brackets 4 to accommodate different sizes of tissues, the distance is reduced by starting the second motor 13, controlling its output shaft to rotate forward, driving the screw 14 to rotate, and the screw 14 drives the lifting frame 15 to move downward in the vertical direction through the threaded engagement. The lifting frame 15 pushes the front and rear movable frames 11 to rotate inward around the shaft pin connected to the support frame 12 through the sliding engagement with the long slide groove of the movable frame 11. The movable frame 11 pushes the front and rear sliding blocks 5 to move closer to each other along the corresponding slide groove through the short slide groove, thereby driving the rotating shaft 3 and the support brackets 4 to move closer together, thus reducing the distance between the two support brackets 4. To increase the spacing: control the output shaft of the second motor 13 to reverse, causing the screw 14 to rotate in the opposite direction, driving the lifting frame 15 to move upward in the vertical direction. The lifting frame 15, in cooperation with the long slide groove, pulls the front and rear movable frames 11 to rotate outward around the pivot pin. The movable frames 11, in turn, push the front and rear sliding blocks 5 to move away from each other along the slide groove through the short slide groove, thereby causing the rotating shaft 3 and the support frame 4 to move away synchronously, thus increasing the spacing between the two support frames 4. After the adjustment is completed, turn off the second motor 13. Utilize the thread self-locking characteristic of the screw 14 to ensure that the positions of the lifting frame 15, movable frame 11 and sliding block 5 are fixed, thereby keeping the two support frames 4 stably in the adjusted spacing position and preventing displacement during operation.
