Description

Technical Field

[0001] This invention relates to the field of quilling workbench technology, and in particular to a CNC workbench for automatic quilling strip rolling. Background Technology

[0002] Paper quilling is a fundamental step in paper quilling art. Usually, the cut paper strips are manually rolled one by one into the required paper rolls using winding tools such as paper rolling needles, cone-shaped rods or electric paper quilling pens. After being glued or shaped, they are used for decorative purposes.

[0003] When rolling paper manually, the operator needs to pick up each piece of paper, align it with the roll, manually control the winding force, and complete the unwinding. This is not only labor-intensive and inefficient, but the diameter, tightness, and flatness of the paper roll are also greatly affected by the operator's experience, making it difficult to ensure the consistency of batch products. Although simple electric paper rollers can achieve rotary winding, they usually only have a single winding function, and the remaining steps still require manual assistance. The degree of automation is low, making it difficult to meet the needs of continuous and batch production.

[0004] Therefore, there is an urgent need for a CNC worktable for automatic rolling of quilling strips to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art and provide an automatic paper quilling strip rolling CNC workbench.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A CNC workbench for automatic quilling strip winding includes a paper storage box, drivers, a controller, a paper lifting mechanism, a feeding mechanism, a conveying mechanism, a winding mechanism, and a loosening mechanism. The paper storage box includes a base and partitions. The feeding mechanism includes paper-feeding rollers. The conveying mechanism includes a conveying roller assembly. The partition array is fixedly mounted on the base, and a paper storage groove is formed between two adjacent partitions. The paper lifting mechanism is mounted on the base. The paper-feeding rollers are rotatably mounted above the paper output end of the paper storage box. Each roller of the conveying roller assembly is rotatably mounted on one side of the paper output end of the paper storage box. The winding mechanism is mounted on the side of the conveying roller assembly away from the paper storage box. The loosening mechanism is mounted on the winding mechanism. The controller is fixedly mounted on one side of the paper storage box. Multiple drivers are respectively connected to the feeding mechanism, the conveying mechanism, the winding mechanism, and the loosening mechanism, and all drivers are electrically connected to the controller.

[0007] Preferably, the paper lifting mechanism includes a lifting plate, a limiting block, an operating rocker arm, a paper lifting linkage, and a paper pressing spring. The lifting plate includes a comb tooth portion and a comb handle portion. Multiple comb teeth portions are respectively located within each of the paper storage slots. The outer contour of the comb tooth portion mates with the inner wall of the paper storage slot. The end of the comb tooth portion away from the paper outlet end of the paper storage box is rotatably connected to the paper storage box. The comb handle portion is fixedly disposed at the end of each comb tooth portion and is located at the paper outlet end of the paper storage box. The limiting block is fixedly disposed at the bottom of the comb handle portion. A limiting step is provided on the base. When the limiting block is pressed down, it abuts against the limiting step. The operating rocker arm is rotatably disposed on the base and located at the lifting plate. Below the cardboard, one end of the paper-lifting linkage is rotatably connected to the limiting block, and the other end of the paper-lifting linkage is rotatably connected to the operating rocker arm. The paper-pressing spring is located between the paper-lifting plate and the base. One end of the paper-pressing spring is fixedly connected to the limiting block, and the other end of the paper-pressing spring is fixedly connected to the base. When it is necessary to fill the paper storage box with paper strips, manually pull the operating rocker arm downwards. The paper-lifting linkage drives the paper-lifting plate to press down. At this time, the quilling strip is placed in the paper storage slot and located on the comb teeth. After filling is completed, release the operating rocker arm. The paper-pressing spring rises upwards, pushing the paper-lifting plate so that the upper surface of the quilling strip can always be in contact with the paper-feeding wheel.

[0008] Preferably, the feeding mechanism further includes an adjusting track, an adjusting slide, a lifting rod, and a mounting frame. The adjusting track is fixedly disposed above the paper outlet end of the paper storage box and extends along the width direction of the paper storage groove. The adjusting slide is slidably disposed on the adjusting track. The mounting frame is disposed below the adjusting slide. The paper feed roller is rotatably disposed on the mounting frame. The lifting rod is disposed between the adjusting slide and the mounting frame. The fixed end of the lifting rod is fixedly connected to the adjusting slide, and the telescopic end of the lifting rod is fixedly connected to the mounting frame. The drivers for the paper roller, adjusting slide, and lifting rod are all electrically connected to the controller. The lifting rod drives the mounting frame to rise, causing the paper roller to leave the quilling strip. The controller controls the adjusting slide to slide along the adjusting track, moving the paper roller to the storage slot where the desired quilling strip is located. The lifting rod descends, causing the paper roller to contact the quilling strip. With the cooperation of the lifting rod and the adjusting slide, the paper roller can move along the adjusting track to above any storage slot. A single paper roller can complete the separate feeding of quilling strips in all storage slots, realizing automated feeding.

[0009] Preferably, the conveying mechanism further includes a paper guide and a tension detector. The conveying roller assembly includes a guide roller, a tension roller, and a traction roller arranged sequentially from the paper storage box to the winding mechanism. Two guide rollers are respectively rotatably disposed on the upper and lower sides of the quilling strip. The paper guide is fixedly disposed between the paper storage box and the guide rollers. The paper guide is a tapered structure that gradually narrows from the paper storage box to the conveying roller assembly. A paper feed groove is formed on the side of the paper guide near the conveying roller assembly. The horizontal height of the paper feed groove is equal to the horizontal height of the contact point between the paper feed roller and the quilling strip. The tension detector is fixedly disposed on the tension roller. The guide roller, tension roller, and traction roller are driven by... Both the actuator and the tension detector are electrically connected to the controller. The paper guide frame guides the quilling strip from the paper feed groove through a tapered inclined surface, ensuring that the quilling strip can enter the gap between the upper and lower guide rollers in parallel, avoiding the quilling strip from deviating or even bending when entering the conveying roller group, thus improving the conveying stability. The traction roller provides traction power, and the tension roller detects the tension of the quilling strip in real time through the tension detector. The controller adjusts the speed of each roller to regulate the conveying tension in a closed loop, keeping the conveying tension of the quilling strip within the set range, avoiding stretching and deformation due to excessive tension or loosening due to insufficient tension, and ensuring continuous, uniform, and stable conveying.

[0010] Preferably, the winding mechanism includes a winding shaft, winding supports, a translation track, a translation slide, paper stop plates, and a centering block. Two winding supports are fixedly mounted on the side of the conveying roller assembly away from the paper storage box. The winding shaft is rotatably mounted on the winding supports and extends along the width direction of the paper storage groove. A clamping groove extending radially along the winding shaft is formed through the winding shaft. The translation track is fixedly mounted below the winding shaft and extends along the width direction of the paper storage groove. The translation slide is slidably mounted on the translation track. Two paper stop plates are slidably sleeved on the winding shaft and located on both sides of the width direction of the quilling strip. The paper stop plates are all mounted on the translation slide. The centering block is fixedly mounted on the translation slide and located between the conveying roller assembly and the winding shaft. A centering groove is provided on the upper part of the winding shaft. The horizontal height of the centering groove is equal to the horizontal height of the winding shaft axis. The winding shaft and the driver of the translation slide are both electrically connected to the controller. The translation slide drives the centering block to move, so that the centering groove is aligned with the future quilling strip, and guides the quilling strip to enter the clamping groove on the winding shaft accurately and parallelly through the centering groove. The axial length of the clamping groove covers the width of the paper storage box. A sensor (not shown in the figure) is fixed on the inner wall of the clamping groove. Two sensors are arranged radially along the winding shaft and are located at the radial far end respectively. When both sensors detect the passage of the paper strip, the winding shaft starts to rotate, driving the quilling strip to wind into a paper roll. The two paper stop discs limit the end faces of the paper roll, constrain the axial width of the paper roll, and ensure that the end faces are flat.

[0011] Preferably, the winding mechanism further includes a pitch-changing assembly, which includes a pitch-changing track, a pitch-changing base, and pitch-changing push rods. The pitch-changing track is fixedly disposed on the top of the translation slide, and its extension direction is parallel to that of the translation track. The pitch-changing base is fixedly disposed in the middle of the pitch-changing track. The paper stoppers slide on the pitch-changing track and are respectively located on symmetrical sides of the pitch-changing base. At least two pitch-changing push rods are respectively disposed between each paper stopper and the pitch-changing base. The fixed ends of the pitch-changing push rods are fixedly connected to the pitch-changing base, and the telescopic ends of the pitch-changing push rods are fixedly connected to each paper stopper. The driver of the pitch-changing push rod is electrically connected to the controller. The pitch-changing push rod drives each paper stopper to move towards or away from each other, thereby changing the distance between the two paper stoppers, realizing the end face limiting of quilling strips of different widths and improving adaptability.

[0012] Preferably, the unwinding mechanism includes unwinding petals and a diameter-changing assembly. Each of the multiple unwinding petals includes a petal body. The paper stop plate includes a first stop plate and a second stop plate. The first stop plate and the second stop plate are respectively located on both sides of the width direction of the quilling strip. Each petal body is installed on the first stop plate and extends toward the second stop plate through the diameter-changing assembly. Each petal body surrounds the outside of the winding shaft and is evenly distributed circumferentially along the winding shaft. The unwinding petal has an avoidance notch. The avoidance notch is opened on the petal body and is located toward the centering block. The clearance notch forms an open notch on the side facing the centering block, allowing the quilling strip to pass smoothly through the petal and into the clamping groove of the winding shaft. It is then wound into a paper roll within the retaining ring formed by the petals. When all the quilling strips have entered the retaining ring, a tight roll is formed. According to the required outer diameter of the paper roll, the diameter of the retaining ring is changed by the diameter-changing component, thereby loosening the tight roll within the retaining ring and realizing online unwinding. This meets the needs of quilling shapes for paper rolls of different diameters and tightness, improving production efficiency and product consistency.

[0013] Preferably, the variable diameter assembly includes a drive gear, a driven gear, and a cam disc. The loosened flap further includes a radial slide and a guide pin. Both the drive gear and the driven gear are rotatably mounted on the first retaining plate. The first retaining plate has a guide groove extending radially along its length. The drive gear is located on the side of the guide groove near the second retaining plate. The driven gear meshes with the drive gear. The cam disc is fixedly mounted on the driven gear and located on the side of the guide groove near the second retaining plate. The cam disc has a through hole and a helical groove. The flap passes through the through hole. Multiple... The helical grooves are all located on the side of the through hole away from the winding shaft. The radial slide is slidably disposed in the guide groove and fixedly connected to the petal body. The guide pin is fixedly disposed on the radial slide and located on one side of the petal body. The guide pin slides in the helical groove. The driver of the drive gear is electrically connected to the controller. The drive gear drives the driven gear to rotate, and the driven gear drives the cam turntable to rotate. The guide pin of the unwinding petal slides along the helical groove, driving the radial slide to move inward or outward along the guide groove, thereby realizing the synchronous radial movement of each petal body and changing the diameter of the retaining ring.

[0014] Preferably, the second baffle has an annular groove that divides it into an inner ring and an outer ring. A connecting plate is fixedly mounted on the side of the second baffle away from the first baffle. The connecting plate spans the inner and outer sides of the annular groove and connects the inner and outer rings. The valve body can pass through the annular groove. When the first and second baffles move toward each other, the annular groove provides a channel for the valve body to penetrate the second baffle. The axial length of the connecting plate is related to the length of the valve body. The axial length of the connecting plate must ensure that when the distance between the first and second baffles is minimal and the depth of the valve body extending into the annular groove is maximum, the opposing end faces of the valve body and the connecting plate still maintain an axial gap, thus ensuring the reliability of the connection between the inner and outer rings while avoiding interference.

[0015] Preferably, the winding shaft includes a rotating part, an insertion part, and a telescopic take-up part connected in sequence. The rotating part is rotatably mounted on a winding support column. One end of the rotating part near the insertion part is fixedly provided with a rod extending towards the insertion part. The insertion part is slidably sleeved on the rod. The fixed end of the telescopic take-up part is fixedly connected to another winding support column away from the rotating part. The other end of the telescopic take-up part is fixedly connected to the end of the insertion part away from the rotating part. The clamping groove is formed on the rotating part and the rod. The driver of the telescopic take-up part is electrically connected to the controller. After the winding and unwinding processes are completed, the translation slide moves the unwinding mechanism and the paper roll on it to the end of the rotating part near the insertion part. The controller controls the telescopic take-up part to move away from the rotating part, causing the insertion part to disengage from the rod, so that the paper roll can be taken out from the end of the clamping groove, reducing the difficulty of take-up and improving the convenience of take-up.

[0016] In summary, the present invention has the following beneficial effects: 1. This invention integrates all the processes of quilling strip rolling onto the same workbench, forming a complete rolling process from paper storage, paper feeding, conveying, winding, and unwinding. It achieves numerical control automation through the coordinated action of drivers and controllers, eliminating the need for operators to pick up each strip of paper individually, manually align the roll, and control the winding force. This effectively reduces labor intensity and improves production efficiency. Furthermore, process parameters such as winding force and feed rate can be set and repeatedly executed, which helps ensure the consistency of batch products and meets the needs of continuous and batch production.

[0017] 2. This invention achieves reliable automatic supply of paper strips from multiple slots through the coordinated operation of the paper lifting mechanism, feeding mechanism, and conveying mechanism; a single paper-feeding roller can feed the quilling strips in different storage slots, eliminating the need to set a separate paper-feeding roller for each storage slot, thus simplifying the feeding mechanism structure; the conical paper guide frame prevents the quilling strips from deflecting or bending when entering the conveying roller group; the tension detector detects the tension of the paper strips in real time, and the controller adjusts the speed of each roller accordingly to maintain the tension of the paper strips within the set range, ensuring continuous and stable conveying, and realizing automatic, continuous, and stable conveying of paper strips of multiple specifications.

[0018] 3. The winding mechanism of the present invention realizes automatic winding and convenient unwinding of quilling strips; the centering block allows the paper strip to enter the clamping groove at a height aligned with the axis of the winding shaft and be clamped and wound, ensuring accurate starting position of winding; the two paper stop discs form a stop on the end face of the paper roll; the variable pitch component precisely adjusts the distance between the paper stop discs to adapt to paper strips of different widths, improving the adaptability of the worktable to paper strips of different specifications and the winding accuracy; when unwinding, the stationary part slides and extends along the axial direction of the insertion rod to remove the paper roll, reducing the difficulty of unwinding and improving the convenience of unwinding.

[0019] 4. In this invention, multiple loosely rolled petals surround the outside of the winding shaft to form a retaining ring, allowing the quilling strip to complete winding within the retaining ring. The diameter-changing component drives each petal to move radially, changing the diameter of the retaining ring. This eliminates the need to replace the winding core or stop the machine for manual intervention, enabling online adjustment of the paper roll diameter and tightness. This meets the needs of quilling designs for paper rolls of different diameters and tightness, improving production efficiency and product consistency. Attached Figure Description

The fixed end of the telescopic take-up part 714 is fixedly connected to another winding support 72 away from the rotating part 712. The other end of the telescopic take-up part 714 is fixedly connected to the end of the plug-in part 713 away from the rotating part 712. A clamping groove 711 is formed on the rotating part 712 and the plug rod 715. The driver 2 of the telescopic take-up part 714 is electrically connected to the controller 3.

[0033] Working principle: According to Figures 1 to 11As shown, during machine operation, the controller 3 uniformly controls the timing and operating parameters of each driver 2, ensuring that each mechanism coordinates its actions in the following sequence: paper storage, paper lifting, paper feeding, paper guiding, winding, width and spacing adjustment, unwinding and diameter adjustment, and unwinding. The operator moves the operating rocker arm 43, causing the lifting plate 41 to press down, placing different colored and wide quilling strips into each paper storage slot 13. After completion, the operating rocker arm 43 is released, and the pressure spring 45 lifts the lifting plate 41, ensuring the top of the quilling strip remains against the paper feeding roller 51, completing multi-slot paper storage. The lifting rod 54 retracts, causing the mounting frame 55 and the paper feeding roller 51 to rise, moving away from the quilling strip. Subsequently, the adjusting slide 53 drives the paper feeding roller 51 to slide along the adjusting track 52. Until it is above the storage trough 13 where the required quilling strip is located, the lifting rod 54 extends and drives the paper-feeding roller 51 to descend until it contacts the paper strip, completing the feeding and positioning; the paper-feeding roller 51 starts, and the paper strip is quilled out of the storage box 1. The quilled paper strip passes through the paper passage trough 621 of the guide frame 62 and enters the conveying roller group 61 in parallel. It is driven by the guide roller 611, tension roller 612 and traction roller 613 to be conveyed to the winding mechanism 7. The controller 3 adjusts the speed of each roller in real time through the feedback signal of the tension detector 63 to maintain stable tension and achieve smooth feeding; the translation slide 74 drives the centering block 76 and the paper stop plate to move until the center line of the centering groove 761 is aligned with the center line of the paper strip to be fed. The paper strip passes through the centering groove 761 of the centering block 76, The paper strip passes through the clearance notch 83 on the petal 811 and enters the clamping groove 715 of the winding shaft 71 in parallel. The variable pitch push rod 773 extends and retracts, causing the first baffle 751 and the second baffle 752 to slide towards or away from each other along the variable pitch track 771, adjusting the distance between the two baffles to match the width of the paper strip. Then, the rotating part 711 of the winding shaft 71 rotates, causing the paper strip to wind into a paper roll within the retaining ring formed by the petals 811, completing the tight winding. The drive gear 821 drives the driven gear 822 and the cam turntable 823 to rotate. The helical groove 825 on the cam turntable 823 pushes the guide pin 813, and the guide pin 813 drives the radial slide 812 to slide radially along the guide groove 7511 on the first baffle 751. This causes the petals 811 to move radially and open, with each petal 811 simultaneously changing its enclosing diameter until the inner diameter of the enclosing diameter equals the required outer diameter of the paper roll, completing the online unwinding. The translational slide 74 moves the paper roll that meets the requirements to the end of the rotating part 711 near the insertion part 712. The variable pitch push rod 773 extends and retracts, causing the first baffle 751 and the second baffle 752 to slide in opposite directions until the paper roll is exposed outside the petals 811. At this time, the operator picks up the paper roll, and the retractable winding part 713 causes the insertion part 712 to slide axially along the insertion rod 714 until the insertion part 712 disengages from the insertion rod 714. The operator can then remove the paper roll from the end of the rotating part 711 for subsequent gluing, shaping, and other operations, completing the unwinding process.
