Description

Technical Field

[0001] This utility model relates to the field of toothpick paper production technology, specifically to a feeding device for toothpick paper production and preparation. Background Technology

[0002] Toothpick paper is paper used to package toothpicks into booklets. In the production process, pulp suitable for paper quality is diluted with water to a certain concentration, and then initially dehydrated in the wire section of the paper machine to form a wet sheet. It is then pressed and dehydrated, and then dried into paper. In the production process of toothpick paper, the paper needs to go through many processes from drying to binding and printing.

[0003] A search revealed that patent application number CN202420319984.9 discloses an oil-resistant paper unwinding device. Although this device achieves rapid feeding and fixed positioning of oil-resistant paper unwinding material by setting up a lifting mechanism and rotating rod, it is difficult to adapt to papers with different thicknesses or tension requirements. This can easily lead to paper loosening or breaking during unwinding. When an emergency stop or replacement of the roll is required, it cannot quickly brake the roll rotation, posing a safety hazard. Furthermore, it cannot directly adjust the width and slit the unwound paper, requiring additional slitting equipment and increasing the complexity of the production line. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a feeding device for the production and preparation of toothpick paper, which solves the problems mentioned in the background art.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows:

[0006] A feeding device for toothpick paper production includes a frame on which a roll of material is rotatably mounted;

[0007] One end of the material roll is provided with a power component, and a motor is installed on the outside of the frame. The motor drives the material roll to rotate through the power component. Guide rollers are installed between the frames, and tensioning components and slitting components are installed between the material roll and the guide rollers.

[0008] The power assembly includes a driven wheel and a transmission rod. The motor is located at one end of the transmission rod, and the two ends of the transmission rod are provided with driving wheels. The driven wheels are located at both ends of the material roll. The transmission rod is connected to the material roll through the driving wheels, the transmission belt, and the driven wheels.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the frames are supported by multiple support beams.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] Multiple support beams enhance the overall structural stability and strength of the frame. During the operation of the feeding device, components such as the material roll, power unit, and slitting unit generate certain weight and vibration. A stable frame structure can withstand these external forces, preventing deformation or shaking of the frame and ensuring the smooth and reliable operation of the entire feeding device, extending the service life of the equipment. It also helps to ensure the accuracy and stability of the feeding process, improving the quality of toothpick paper production.

[0013] Furthermore, a protective cover is provided on the outer side of the driven wheel, and first guide plates are provided at both ends of the material roll. Side stops are installed at both ends of the first guide plates, and guide wheels are installed on the side stops. The first guide plates rotate on the outer side of the material roll through the cooperation of the guide wheels and the protective cover. The material roll passes through the first guide plates for guided discharge. The first guide plates are deflected by their own gravity, thereby causing the material roll passing through the first guide plates to tighten.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The protective cover on the outside of the driven pulley serves a protective function, preventing dust and debris from entering the transmission parts between the driven pulley and the drive belt, reducing wear and malfunctions, and ensuring the stability of power transmission. The first guide plate has multiple functions. Firstly, by cooperating with the guide wheel and the protective cover, the first guide plate rotates outside the material roll, guiding the roll out along a predetermined path, preventing deviation and ensuring accurate feeding. Secondly, the first guide plate deflects under its own weight, applying pressure to the passing material roll, achieving initial tension and maintaining appropriate tension during subsequent processing, which helps improve the production quality of toothpick paper.

[0016] Furthermore, a brake module is provided on the outside of the power assembly on the frame. The brake module includes a brake cylinder and a brake lever. The brake lever is driven by the brake cylinder to contact the driven wheel.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The brake module provides effective braking control for the feeding device. During production, in case of emergencies requiring immediate cessation of the material roll rotation, or during equipment maintenance or material roll replacement, the operator can control the brake cylinder to engage the brake block with the driven wheel. The friction between the brake block and the driven wheel quickly and effectively stops the material roll rotation, preventing potential safety accidents or equipment damage caused by continued rotation, thus ensuring the safety of the production process and the reliability of the equipment.

[0019] Furthermore, the tensioning assembly is provided with connecting pipes, and a limit rod is connected between the connecting pipes. The two ends of the limit rod are provided with threaded rods. The limit rod is threadedly connected to the connecting pipe through the threaded rods. A second guide plate is installed on the limit rod through a torsion spring. The second guide plate is deflected by the torsion spring, so that the material roll is tensioned again when it passes through the second guide plate.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The tensioning assembly provides further tension to the material roll. The limiting rod is threaded to the connecting pipe, allowing for easy adjustment of its position to suit different production needs. The second guide plate is mounted on the limiting rod via a torsion spring. As the material roll passes the second guide plate, the spring force deflects the guide plate, applying additional tension. This multi-stage tensioning ensures the material roll maintains appropriate tension throughout the feeding process, preventing issues like slackness and wrinkles, thus improving the production quality of toothpick paper and facilitating subsequent processing.

[0022] Furthermore, the slitting assembly is equipped with a fixing plate, which is installed on the inner surface of the frame. A longitudinal slide rail is mounted on the fixing plate, and a first slider is slidably mounted on the longitudinal slide rail. A crossbeam is mounted on the first slider, and lifting cylinders are mounted at both ends of the crossbeam. The crossbeam moves longitudinally via the lifting cylinders, the longitudinal slide rail, and the first slider. A transverse slide rail is mounted on the crossbeam, and a second slider is mounted on the transverse slide rail. A blade holder is mounted on the second slider, and a blade is mounted on the blade holder. The blade slides laterally on the crossbeam via the transverse slide rail and the second slider. A clamping bolt is provided on the blade holder, and the blade holder is locked and fixed after sliding. When the material roll is discharged, it is slid by the blade.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The slitting assembly boasts high flexibility and adjustability. Controlled by a lifting cylinder, the crossbeam moves along the longitudinal slide rail, and the blade holder slides laterally on the crossbeam. Operators can precisely adjust the blade position to meet varying production needs, enabling the slitting of material rolls to different widths and sizes. The blade holder is locked in place by clamping bolts after sliding, ensuring blade stability during slitting and guaranteeing accuracy and quality. This adjustable slitting structure enhances the versatility of the feeding device, meeting diverse production requirements and reducing production costs.

[0025] This utility model provides a feeding device for the production of toothpick paper. It has the following beneficial effects:

[0026] The motor drives the material roll to rotate via a power assembly, which employs a transmission structure consisting of a drive rod, a driving pulley, a drive belt, and a driven pulley. This structure stably and efficiently transmits the motor's power to the material roll, ensuring smooth rotation and guaranteeing continuous and stable feeding. A brake module effectively controls the material roll's rotation. A brake cylinder engages a brake block with the driven pulley, enabling rapid braking of the material roll when needed, such as in emergencies or during equipment maintenance, thus ensuring production safety.

[0027] The device features multi-stage tensioning. The first guide plates at both ends of the roll deflect under their own weight, providing initial tension. The first guide plate in the tensioning assembly deflects via torsion springs, further tightening the roll. This multi-stage tensioning prevents the roll from loosening or wrinkling during feeding, ensuring the quality of the toothpick paper and smooth subsequent processing. The first guide plates at both ends of the roll, in conjunction with guide wheels, guards, and guide rollers between frames, guide the roll along a predetermined path, preventing deviation and ensuring accurate and stable feeding.

[0028] The crossbeam in the slitting assembly can move longitudinally, and the blade holder can slide laterally, and can be locked in place by clamping bolts after sliding. This design allows the blade position to be flexibly adjusted according to different production needs, meeting the slitting requirements of toothpick paper of various widths and sizes, and improving the versatility of the device. The structural design of the slitting assembly ensures the stability of the blades during slitting. The cooperation of each component ensures slitting accuracy and quality, resulting in toothpick paper with neat edges and accurate dimensions.

[0029] The frames are supported by multiple support beams, enhancing their stability and strength. This allows them to withstand the weight of components such as the material rolls, power units, and slitting components, as well as vibrations generated during operation, ensuring stable operation of the entire feeding device. The components are relatively independent yet work together, employing a modular design. This design facilitates installation, commissioning, maintenance, and component replacement, reducing maintenance costs and complexity, and improving maintainability and lifespan.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figures 1 to 7 As shown, the embodiments provided by this utility model are as follows:

[0043] Example 1

[0044] A feeding device for toothpick paper production includes a frame 2, which is supported by multiple support beams 3. These support beams enhance the overall structural stability and strength of the frame 2. During operation, components such as the material roll 4, power assembly 5, and slitting assembly 7 generate weight and vibration. The stable frame 2 structure can withstand these external forces, preventing deformation or shaking, ensuring smooth and reliable operation of the entire feeding device, extending its service life, and also contributing to the accuracy and stability of the feeding process, thus improving the quality of toothpick paper production. The material roll 4 is rotatably mounted on the frame 2, with the power assembly 5 at one end. A motor 1 is mounted on the outside of the frame 2, driving the material roll 4 to rotate via the power assembly 5. A brake module 505 is located on the outside of the power assembly 5 on the frame 2. The brake module 505 includes a brake cylinder 507 and a brake lever 506. The brake lever 506 is driven by the brake cylinder 507 to contact the driven wheel 501. The brake module 505 provides effective braking control for the feeding device. During production, when an emergency occurs and the rotation of the material roll 4 needs to be stopped immediately, or when performing equipment maintenance or replacing the material roll 4, the operator can control the brake cylinder 507 to make the brake block contact the driven wheel 501. The friction between the brake block and the driven wheel 501 can quickly and effectively stop the rotation of the material roll 4, avoiding potential safety accidents or equipment damage caused by the continued rotation of the material roll 4, thus ensuring the safety of the production process and the reliability of the equipment. Guide rollers 8 are installed between the frames 2, and tensioning assembly 6 and slitting assembly 7 are installed between the material roll 4 and the guide rollers 8. The tensioning assembly 6 is provided with connecting pipes 602, and limit rods 603 are connected between the connecting pipes 602. The two ends of the limit rods 603 are provided with threaded rods 604. The limit rods 603 are threaded to the connecting pipes 602 through the threaded rods 604. A second guide plate 601 is installed on the limit rods 603 through a torsion spring. The second guide plate 601 is deflected by the torsion spring, so that the material roll 4 is tensioned again when it passes through the second guide plate 601. The tensioning assembly 6 can further tension the material roll 4. The limiting rod 603 is threadedly connected to the connecting pipe 602 via a threaded rod 604. This connection method facilitates the adjustment of the position of the limiting rod 603 to adapt to different production needs. The second guide plate 601 is mounted on the limiting rod 603 via a torsion spring. When the material coil 4 passes through the second guide plate 601, the elastic force of the torsion spring causes the second guide plate 601 to deflect, thereby applying additional tension force to the material coil 4.Multi-stage tensioning ensures that the material roll 4 maintains appropriate tension throughout the feeding process, preventing problems such as loosening and wrinkling of the material roll 4, thus improving the production quality of toothpick paper and facilitating subsequent processing. The slitting assembly 7 is equipped with a fixing plate 701, which is installed on the inner surface of the frame 2. A longitudinal slide rail 702 is installed on the fixing plate 701, and a first slider 703 is slidably installed on the longitudinal slide rail 702. A crossbeam 705 is installed on the first slider 703, and lifting cylinders 706 are installed at both ends of the crossbeam 705. The crossbeam 705 is connected to the longitudinal slide rail 702 by the lifting cylinders 706 and the lifting cylinders 706. The guide rail 702 and the first slider 703 move longitudinally. A transverse slide rail 704 is installed on the crossbeam 705, and a second slider 707 is installed on the transverse slide rail 704. A knife holder 708 is installed on the second slider 707, and a blade 709 is installed on the knife holder 708. The blade 709 slides laterally on the crossbeam 705 via the transverse slide rail 704 and the second slider 707. The knife holder 708 is equipped with clamping bolts, which lock and fix it after sliding. When the material roll 4 is discharged, it is cut by the blade 709. The cutting assembly 7 has high flexibility and adjustability. The movement of the crossbeam 705 on the longitudinal slide rail 702 and the lateral sliding of the knife holder 708 on the crossbeam 705 are controlled by the lifting cylinder 706. The operator can precisely adjust the position of the blade 709 according to different production needs to achieve cutting of the material roll 4 with different widths and sizes. After the blade holder 708 slides, it is locked in place by clamping bolts, ensuring the stability of the blade 709 position during the slitting process and guaranteeing slitting accuracy and quality. This adjustable slitting structure improves the versatility of the feeding device, meets diverse production requirements, and reduces production costs.

[0045] Example 2

[0046] To maintain tension during the discharge of material coil 4, for example, such as Figures 1 to 7As shown, this utility model also includes: a power assembly 5 comprising a driven wheel 501 and a transmission rod 504, a motor 1 located at one end of the transmission rod 504, driving wheels 503 located at both ends of the transmission rod 504, driven wheels 501 located at both ends of the material roll 4, the transmission rod 504 being connected to the material roll 4 via the driving wheels 503, a transmission belt 502, and the driven wheels 501, a protective cover 509 located on the outer side of the driven wheel 501, and first guide plates 401 located at both ends of the material roll 4, with side stops 508 mounted on both ends of the first guide plates 401. Equipped with guide wheels 510, the first guide plate 401 rotates on the outside of the material roll 4 through the cooperation of the guide wheels 510 and the protective cover 509. The material roll 4 passes through the first guide plate 401 for guidance and discharge. The first guide plate 401 deflects under its own gravity, thereby tightening the material roll 4 that passes through the first guide plate 401. The protective cover 509 on the outside of the driven wheel 501 can play a protective role, preventing dust, debris and other objects from entering the transmission part between the driven wheel 501 and the transmission belt 502, reducing wear and failure, and ensuring the stability of power transmission. The first guide plate 401 has multiple functions. On the one hand, the first guide plate 401 rotates on the outside of the material roll 4 through the cooperation of the guide wheel 510 and the protective cover 509, which can guide the material roll 4 to exit along the predetermined path, avoid the material roll 4 from deviating, and ensure the accuracy of feeding. On the other hand, the first guide plate 401 deflects by its own gravity, applying a certain pressure to the material roll 4 that passes through, realizing the initial tension of the material roll 4, so that the material roll 4 maintains a suitable tension in the subsequent processing, which is conducive to improving the production quality of toothpick paper.

[0047] Working principle:

[0048] Motor 1 is mounted on the outside of frame 2 and is connected to power assembly 5. Power assembly 5 includes transmission rod 504, drive wheel 503, transmission belt 502, and driven wheel 501. After motor 1 starts, its power is transmitted to transmission rod 504, and the drive wheels 503 at both ends of transmission rod 504 rotate accordingly. The drive wheels 503 drive the driven wheels 501 located at both ends of material roll 4 to rotate through transmission belt 502, thereby realizing the rotation of material roll 4 and providing power for feeding. When the operator turns on motor 1, motor 1 starts running, and power is transmitted to driven wheel 501 through transmission rod 504, drive wheel 503, and transmission belt 502. Driven wheel 501 drives material roll 4 to start rotating, and the feeding device enters the working state.

[0049] The material roll 4 has first guide plates 401 at both ends. Side stops 508 and guide wheels 510 are installed at both ends of the first guide plates 401. The first guide plates 401 rotate outside the material roll 4 through the cooperation of the guide wheels 510 and the protective cover 509 on the outer side of the driven wheel 501. The material roll 4 passes through the first guide plates 401 for discharge. Due to its own gravity, the first guide plates 401 deflect, which initially tightens the material roll 4 and guides it to move in a predetermined direction, preventing deviation. As the material roll 4 rotates, the paper on it passes through the first guide plates 401. The first guide plates 401 naturally deflect under gravity, causing the paper to initially tighten and move in the correct direction during discharge.

[0050] A brake module 505 is located on the outside of the power assembly 5 on the frame 2. The brake module 505 includes a brake cylinder 507 and a brake block. When it is necessary to stop the rotation of the material roll 4, the brake cylinder 507 is activated, causing the brake block to contact the driven wheel 501. Through friction, the driven wheel 501 stops rotating, thereby stopping the rotation of the material roll 4. During production, if an emergency occurs or feeding needs to be paused, the operator controls the brake cylinder 507 to activate, causing the brake block to contact the driven wheel 501, and the material roll 4 stops rotating. When feeding needs to continue, the brake cylinder 507 causes the brake block to separate from the driven wheel 501, and the material roll 4 continues to rotate under the drive of the power assembly 5.

[0051] A tensioning assembly 6 is installed between the material coil 4 and the guide roller 8. A limiting rod 603 is connected between the connecting pipes 602 in the tensioning assembly 6. Both ends of the limiting rod 603 are threaded to the connecting pipes 602 via threaded rods 604. A second guide plate 601 is mounted on the limiting rod 603 via a torsion spring. When the material coil 4 passes the second guide plate 601, the second guide plate 601 deflects under the action of the torsion spring, further tensioning the material coil 4 to ensure it maintains appropriate tension during subsequent processing. After initial tensioning, the material coil 4 continues to move, passing the second guide plate 601 of the tensioning assembly 6. The second guide plate 601 deflects under the action of the torsion spring, applying pressure to the material coil 4 for further tensioning.

[0052] The slitting assembly 7 is used to slit the material roll 4. A fixing plate 701 of the slitting assembly 7 is mounted on the inner surface of the frame 2. The fixing plate 701 has a longitudinal slide rail 702. A first slider 703 on the slide rail can drive the crossbeam 705 to move longitudinally. Lifting cylinders 706 at both ends of the crossbeam 705 can control the longitudinal movement of the crossbeam 705. A transverse slide rail 704 is mounted on the crossbeam 705. A second slider 707 can drive the blade holder 708 to slide laterally on the crossbeam 705. A blade 709 is mounted on the blade holder 708. The blade 709 can be adjusted in position by moving laterally and longitudinally to meet different slitting requirements. After the blade holder 708 slides, it is locked in place by clamping bolts to ensure the stability of the blade 709 during the slitting process. After being tensioned, the material roll 4 moves to the slitting assembly 7. According to production requirements, the operator controls the lifting cylinder 706 to move the crossbeam 705 longitudinally, while simultaneously adjusting the lateral position of the blade holder 708 on the crossbeam 705. After adjustment, the blade holder 708 is fixed with clamping bolts. When the material roll 4 is discharged, the blade 709 slits the material roll 4, dividing it into the required size.

[0053] Guide rollers 8 are installed between the frames 2. Under the guidance of the guide rollers 8, the slit rolls 4 continue to be discharged along a stable path, ensuring that the slit toothpick paper smoothly enters the subsequent processing stage. The slit rolls 4 are discharged along a predetermined direction under the action of the guide rollers 8, and enter the next production process.
