Description

Technical Field

[0001] This utility model relates to the field of drainage board technology, specifically to an automatic winding and rolling device for drainage boards. Background Technology

[0002] As is well known, plastic drainage boards are made of polystyrene or polyethylene as raw material. The plastic base plate is stamped to form conical protrusions or stiffening ribs or hollow cylindrical porous shapes. After the drainage board is produced, it needs to be rolled up.

[0003] Existing automatic winding and coiling devices lack precise guidance and tension adjustment through purely mechanical structures, which makes it easy for the drainage board to deviate during the coiling process and for the coiling tension to be uneven. The resulting coils are loose and have inconsistent diameters, affecting subsequent storage, transportation and secondary use. Utility Model Content

[0004] In order to overcome the problems of easy deviation, uneven winding tightness, and loose roll in the existing drainage board winding device, this utility model provides an automatic winding and rolling device for drainage boards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic winding and rolling device for drainage boards, comprising: frame; A winding roller is horizontally positioned in the middle of the frame, with both ends of the winding roller rotatably connected to the frame. A guide assembly is located on the side of the frame near the winding roller; A tension adjustment assembly is provided between the guide assembly and the winding roller, and includes an adjustment frame, an elastic element and a pressure roller. The adjustment frame is fixedly connected to the machine frame, one end of the elastic element is connected to the adjustment frame and the other end is connected to the pressure roller, and the pressure roller is in contact with the surface of the drainage plate. Limiting components, which are respectively sleeved on both ends of the winding roller; A drive assembly, wherein the drive assembly is disposed at one end of the frame; An overlap positioning groove, wherein the overlap positioning groove is formed on the surface of the winding roller and extends along the axial direction of the winding roller; and An anti-slip sleeve is fitted onto the outside of the winding roller, covering the surface of the winding roller, and the outer surface of the anti-slip sleeve is provided with anti-slip texture.

[0006] Preferably, the guiding assembly includes a guide frame and guide rollers. The guide frame is fixedly connected to the machine frame. The guide rollers are distributed at intervals along the vertical direction and are rotatably disposed within the guide frame. The surface of the guide rollers is a smooth curved surface. The spacing between adjacent guide rollers is adapted to the thickness of the drainage plate. The axis of the guide rollers is parallel to the axis of the winding roller.

[0007] Furthermore, the elastic element is a helical spring, which is arranged along the height direction of the pressure roller. In its natural state, the elastic element keeps the pressure roller tending to press downward.

[0008] Furthermore, the limiting assembly includes two limiting plates, which are respectively sleeved on both ends of the winding roller. The limiting plates are detachably connected to the winding roller. The inner surface of the limiting plate is a smooth plane. The limiting plate has a plate-shaped structure. A mounting hole is opened in the center of the limiting plate. A fastening bolt is provided on the inner wall of the mounting hole. The fastening bolt passes through the limiting plate and abuts against the frame for fixation.

[0009] In a further embodiment, the drive assembly includes a drive shaft, transmission gears, and a crank handle. The drive shaft is rotatably connected to the frame. The transmission gears are fixed to the ends of the drive shaft and the winding roller, respectively, and the two transmission gears mesh with each other. The crank handle is fixedly connected to one end of the drive shaft. The transmission gears are spur gears, and the two transmission gears have the same module.

[0012] Furthermore, based on the aforementioned solution, the bottom of the frame is provided with support feet, which are fixedly connected to the frame, and the bottom of the support feet is a flat contact surface.

[0013] Beneficial effects This automatic winding and coiling device for drainage boards features a guide assembly with multiple sets of guide rollers forming a directional channel to limit lateral deviation of the drainage board and ensure axial alignment along the winding roller during the coiling process. The elastic element of the tension adjustment assembly drives the pressure roller to continuously adhere to the drainage board, automatically compensating for tension changes during the winding process and preventing uneven tension of the roll. Limiting plates at both ends of the winding roller form a clamping space to limit the winding range of the drainage board and prevent edge misalignment. The anti-slip sleeve on the surface of the winding roller increases the friction with the drainage board. The overlapping positioning groove fixes the starting end, and with the stable drive of the gear transmission, the roll is tightly wound.

[0014] The guide and limit components work together to reduce the rolling deviation rate and significantly improve the neatness of the roll edges. The tension adjustment component ensures consistent roll tightness and reduces loosening rate. The purely mechanical drive component provides stable transmission and convenient operation, requiring no electricity for outdoor construction scenarios. The anti-slip sleeve and overlap positioning groove work together to make the roll tight and not easy to loosen, improving integrity during storage and transportation and reducing losses.

[0017] 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.

[0018] See Figures 1-5 An automatic winding and rolling device for drainage boards is disclosed. A frame 1 serves as the foundation of the device, with support feet 21 at the bottom for stability. A winding roller 2 is horizontally mounted in the middle. A guide assembly 3 and a tension adjustment assembly 4 are arranged sequentially on one side of the frame 1. Limiting assemblies 8 are fitted at both ends of the winding roller 2, and a drive assembly 9 is mounted at one end. The surface of the winding roller 2 has overlapping positioning grooves 10 and anti-slip sleeves 11. The guide assembly 3 forms a directional channel to guide the drainage board and prevent it from deviating during winding. The tension adjustment assembly 4, through an elastic element 6, drives a pressure roller 7 to adhere to the drainage board, automatically compensating for tension changes. To prevent uneven tension of the roll, the limiting component 8 limits the winding range and avoids edge misalignment. The driving component 9 drives the winding roller 2 to rotate stably through gear transmission. The overlapping positioning groove 10 fixes the starting end of the drainage board, and the anti-slip sleeve 11 increases friction to ensure the roll is tight. Through the synergy of guiding positioning, tension self-adaptation, limiting and anti-deviation, stable driving, and tight winding, the components solve the problems of winding deviation, uneven tension, and loose roll in traditional devices, and achieve efficient and regular winding of the drainage board, which is suitable for storage and transportation needs in various scenarios such as production and construction.

[0019] First, refer to Figure 1 In this embodiment, the frame 1 is a frame structure with strong overall rigidity, which can stably support all components such as the winding roller 2, the guide assembly 3, and the drive assembly 9. It will not deform even under long-term winding tension and equipment weight, providing a stable foundation for the winding operation. The frame 1 has a reasonable structural layout, with reserved installation space for the winding roller 2 in the middle, one side providing installation positions for the guide assembly 3 and the tension adjustment assembly 4, and one end reserving transmission space for the drive assembly 9. After the components are installed, they can move smoothly together without interference.

[0020] The support foot 21 is fixed to the bottom of the frame 1. The bottom end is a flat contact surface, which can increase the contact area with the ground and make the device stable. Even if vibration occurs during the winding process, it will not shift. The height design of the support foot 21 ensures that the winding roller 2 is in a horizontal state, avoiding the drainage plate from shifting due to tilting, and ensuring the roll is neat.

[0021] Then, refer to Figure 1 In this embodiment, the winding roller 2 is installed in the middle of the frame 1 in the horizontal direction, and its two ends are rotatably connected to the frame 1. It is the core carrier for winding and rolling the drainage board. The surface of the winding roller 2 is smooth. With the anti-slip sleeve 11 and the overlapping positioning groove 10, it can ensure that the drainage board can be wound smoothly and that the roll is tight and not loose.

[0022] The anti-slip sleeve 11 is fitted on the outside of the winding roller 2, covering the entire winding surface. The outer surface is provided with anti-slip texture. The anti-slip texture can increase the friction between the winding roller 2 and the drainage plate, prevent the drainage plate from slipping during the winding process, ensure the roll is tight, and at the same time reduce the wear on the surface of the drainage plate and protect the structural integrity of the drainage plate.

[0023] The overlap positioning groove 10 is opened on the surface of the winding roller 2 and extends along the axial direction. The inner wall is provided with anti-slip protrusions 20. When winding, the starting end of the drainage plate is embedded in the overlap positioning groove 10. The anti-slip protrusions 20 enhance the fixing effect, prevent the starting end from loosening and shifting, lay the foundation for subsequent winding, and ensure that the roll remains regular from the starting end.

[0024] Secondly, see Figure 4 In this embodiment, the guide assembly 3 is installed on the side of the frame 1 near the winding roller 2. It is the key to preventing the winding from deviating. It guides the drainage plate through the directional channel to ensure that it is aligned and wound along the axial direction of the winding roller 2. It includes a guide frame 12 and a guide roller 13. The guide frame 12 is fixedly connected to the frame 1 and has a stable structure. It provides a precise installation reference for the guide roller 13 and ensures that the installation position of the guide roller 13 is parallel to the winding roller 2, thus avoiding the drainage plate from deviating due to installation tilt.

[0025] Guide rollers 13 are distributed vertically at intervals and are rotatably installed inside the guide frame 12. Their surfaces are smooth curved surfaces. The spacing between adjacent guide rollers 13 is adapted to the thickness of the drainage plate. The drainage plate passes through the adjacent guide rollers 13 to form a directional channel. The guide rollers 13 rotate synchronously with the drainage plate, converting sliding friction into rolling friction, reducing resistance, and limiting the lateral movement of the drainage plate to ensure that it is always conveyed to the winding roller 2 in the preset direction, avoiding left and right deviations during the winding process.

[0026] Again, see Figure 2 In this embodiment, the tension adjustment component 4 is located between the guide component 3 and the winding roller 2. It is the key to solving the problem of uneven tension of the roll. It automatically compensates for tension changes through elastic pressure. It includes an adjustment frame 5, an elastic element 6 and a pressure roller 7. The adjustment frame 5 is fixedly connected to the frame 1, providing stable installation and movement space for the elastic element 6 and the pressure roller 7, ensuring that the pressure roller 7 can move flexibly in the vertical direction to adapt to tension changes.

[0027] One end of the elastic element 6 is connected to the adjusting frame 5, and the other end is connected to the pressure roller 7. In its natural state, the pressure roller 7 maintains a downward pressing tendency. During the rolling process, when the tension of the drainage board is too high, the pressure roller 7 is pushed upward, and the elastic element 6 contracts to buffer the tension. When the tension of the drainage board is too low, the elastic element 6 extends to push the pressure roller 7 downward to press the drainage board and replenish the tension. Through this automatic compensation mechanism, the tension of the drainage board is kept stable throughout the rolling process, and the roll is kept tight and loose without any looseness or excessive stretching.

[0028] The pressure roller 7 has a smooth surface that fits tightly against the surface of the drainage board. This prevents damage to the drainage board and ensures uniform pressure distribution, resulting in even tension adjustment and further guaranteeing the neatness of the roll.

[0029] In addition, see Figure 3 In this embodiment, the limiting component 8 is sleeved on both ends of the winding roller 2 to limit the winding range of the drainage plate and prevent edge misalignment and deviation. It includes two limiting plates 14, which are plate-shaped structures with mounting holes 15 in the center. They are sleeved on both ends of the winding roller 2 through the mounting holes 15 and are detachably connected to the winding roller 2. The inner wall of the limiting plate 14 is provided with fastening bolts 16, which pass through the limiting plate 14 and abut against the frame 1 to fix it. This can quickly lock the position of the limiting plate 14 and prevent the limiting plate 14 from shifting during the winding process.

[0030] The inner surfaces of the two limiting plates 14 are smooth planes, forming a clamping space that matches the width of the drainage plate. The drainage plate is wound within this space and will not exceed the range, avoiding edge misalignment and curling. The smooth surface of the limiting plate 14 reduces friction with the edge of the drainage plate, preventing damage to the edge of the drainage plate, while ensuring that the edge of the roll is neat, improving the convenience of subsequent storage and transportation.

[0031] Finally, see Figure 4 In this embodiment, the drive assembly 9 is installed at one end of the frame 1 to provide stable rotational power for the winding roller 2, thereby realizing automatic winding of the drainage board. It includes a drive shaft 17, a transmission gear 18 and a crank 19. The drive shaft 17 is rotatably connected to the frame 1. The transmission gear 18 is fixed at the ends of the drive shaft 17 and the winding roller 2 respectively. The two transmission gears 18 mesh with each other and have the same module to ensure smooth transmission. When the drive shaft 17 is rotated, the winding roller 2 is driven to rotate synchronously through gear meshing. The transmission efficiency is high, there is no slippage, and the winding speed is uniform.

[0032] The crank handle 19 is fixed to one end of the drive shaft 17, making it convenient for operators to manually rotate. It does not require electric drive and is suitable for outdoor construction and other power-free scenarios. The crank handle 19 is ergonomically designed, comfortable to hold, and easy to rotate, reducing the labor intensity of operators. At the same time, it can flexibly control the winding speed according to the actual situation to ensure a smooth winding process.

[0033] Working principle: When using this automatic winding and rolling device for drainage boards, first check whether the connections of each component are firm, the frame 1 and the support foot 21 are securely fixed without looseness, the winding roller 2 rotates smoothly without jamming or abnormal noise, the guide roller 13 of the guide assembly 3 rotates flexibly with a smooth and undamaged surface, the elastic element 6 of the tension adjustment assembly 4 extends and retracts freely, the pressure roller 7 is not deformed and can move up and down smoothly, the limit plate 14 of the limit assembly 8 is firmly installed, the fastening bolt 16 can effectively lock the position, the transmission gear 18 of the drive assembly 9 meshes tightly, and the crank handle 19 rotates without resistance.

[0034] According to the width of the drainage board to be rolled, adjust the distance between the limiting plates 14 at both ends of the winding roller 2, loosen the fastening bolts 16, move the limiting plates 14 to the preset position, ensure that the distance is adapted to the width of the drainage board, and then tighten the fastening bolts 16 to lock it. Check the distance between the adjacent guide rollers 13 of the guide assembly 3 to ensure that it is adapted to the thickness of the drainage board, so that it can guide the drainage board without excessive compression causing deformation. Confirm that the width of the overlapping positioning groove 10 is adapted to the edge of the drainage board and can firmly fix the starting end.

[0035] Place the device on a flat surface, ensuring that the flat contact surface of the support leg 21 is in close contact with the ground, and that the device is level and not tilted. Clean up any debris in the rolling area and leave enough space for storing and retrieving the rolls.

[0036] Pass one end of the drainage board between the adjacent guide rollers 13 of the guide assembly 3 to ensure that the drainage board is smoothly conveyed along the channel formed by the guide rollers 13 without deviation. Continue to pull the drainage board so that it passes under the pressure roller 7 of the tension adjustment assembly 4. The pressure roller 7 naturally presses the surface of the drainage board under the action of the elastic element 6.

[0037] Embed the starting end of the drainage board into the overlapping positioning groove 10 on the surface of the winding roller 2, ensuring that the edge of the drainage board fits tightly against the inner wall of the positioning groove. The anti-slip protrusion 20 enhances the fixing effect and prevents the starting end from loosening. Gently pull the drainage board to confirm that the starting end is firmly fixed and there is no risk of displacement.

[0038] The operator holds the crank handle 19 and rotates the drive shaft 17 clockwise. Through the meshing of the transmission gear 18, the winding roller 2 rotates synchronously, and the drainage board begins to wind onto the winding roller 2. During the rotation, the crank handle 19 is kept at a uniform speed to avoid uneven tension of the roll due to sudden changes in speed.

[0039] During the winding process, the tension adjustment component 4 works in real time. When the conveying speed of the drainage board is inconsistent with the winding speed, causing tension changes, the pressure roller 7 moves up and down automatically under the action of the elastic element 6 to compensate for the tension. When the tension is too high, the pressure roller 7 moves up to buffer; when the tension is too low, the pressure roller 7 moves down to press, ensuring that the tension of the roll is consistent.

[0040] Observe the winding state of the drainage board. The limiting plate 14 limits the winding range. The drainage board is always wound between the two limiting plates 14. There will be no edge misalignment or deviation. If a slight deviation is found, the position of the guide component 3 can be finely adjusted or the drainage board can be manually and gently corrected to ensure that the edge of the roll is neat.

[0041] Continue turning the crank 19 until the drainage board is wound to the preset roll diameter, or the drainage board is completely wound. During the winding process, the anti-slip sleeve 11 increases the friction to prevent the drainage board from slipping, and the roll remains tight at all times.

[0042] Once the preset roll diameter is reached or the drainage board is wound, stop turning the crank 19, and the winding roller 2 will stop rotating.

[0043] Secure the finished drainage board roll with straps or ropes to prevent it from loosening. Distribute the securing points evenly to ensure the overall stability of the roll.

[0044] Loosen the fastening bolts 16 of the limiting plates 14 at both ends of the winding roller 2, and remove the limiting plates 14 from both ends of the winding roller 2 to reserve space for the removal of the roll body.

[0045] Gently support both sides of the roll and remove it from the winding roller 2. Place it in the preset storage area to avoid squeezing or collision, and ensure that the roll is intact.

[0046] After the winding operation is completed, clean the dust and debris from the surfaces of the winding roller 2, guide roller 13, and pressure roller 7 to prevent residual impurities from affecting the next winding. Clean the dirt in the overlapping positioning groove 10 to ensure the starting end is fixed.

[0047] Regularly inspect the elastic element 6 of the tension adjustment component 4. If the elasticity decreases or deforms, replace it in time. Check the meshing of the transmission gear 18. If wear or excessive clearance occurs, deal with it in time. Check the fastening bolts 16 of the limit plate 14 to ensure that the threads are intact and the locking is reliable. Check the anti-slip texture of the anti-slip sleeve 11. If it is severely worn, replace it in time to ensure friction.

[0048] After maintenance and cleaning, reposition the limit plate 14 onto both ends of the winding roller 2, adjust it to the initial position and lock it, reset the pressure roller 7 to its natural state, and shake the crank 19 to restore the winding roller 2 to its initial position, preparing it for the next use.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
