Description

Technical Field

[0001] This utility model relates to the technical field of waterproof membrane production equipment, and in particular to a waterproof membrane waste material recycling and winding device. Background Technology

[0002] In building waterproofing projects, materials such as SBS modified bitumen waterproofing membranes and polymer TPO / PVC membranes are widely used in waterproofing construction of roofs, basements, tunnels, and bridges. During actual installation, to accommodate complex structural dimensions, it is often necessary to cut the entire roll of material, resulting in a large amount of strip or sheet-like scraps. If these scraps are piled up haphazardly, they not only occupy construction site space but are also susceptible to aging and degradation due to dust, rainwater, and ultraviolet radiation, reducing their recycling value. Therefore, the centralized collection and orderly processing of waterproofing membrane scraps has become a crucial step in improving the level of civilized construction and resource recycling rates on construction sites.

[0003] Currently, most construction sites still use manual bundling or simple wrapping to handle leftover materials. This process relies heavily on worker experience and lacks standardized procedures, resulting in loose bundling, irregular shapes, and easy unraveling during transport, making subsequent recycling difficult. While some equipment has basic winding functions, it lacks adaptive adjustment mechanisms for leftover materials of different widths, failing to achieve precise guidance and effective limiting. This causes materials to easily shift, wrinkle, or even jam during transport, severely impacting winding quality and operational continuity.

[0004] Therefore, it is necessary to design a waterproof membrane scrap recycling and winding device to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of inconvenient limit adjustment, loose winding, and irregular bundling, this utility model provides a waterproof membrane scrap recycling and winding device.

[0006] The technical solution is as follows: A waterproof membrane scrap recycling and winding device includes a base plate, a bracket, a controller, a frame, a sponge pad, an electric slide rail, an electric slider, a limiting plate, and conveying rollers. Two brackets are fixedly connected to the rear top of the base plate, and the controller is fixedly connected to the outer side of the left bracket. The frame is fixedly connected to the front top of the base plate. Sponge pads are provided at the front and rear edges of the top of the frame. Electric slide rails are fixedly connected to both the front and rear sides of the frame. The electric slide rails are electrically connected to the controller. Two electric sliders are slidably connected to each electric slide rail. The electric sliders are electrically connected to the controller. Limiting plates are fixedly connected between the corresponding front and rear electric sliders. Multiple conveying rollers are rotatably connected inside the frame along its length.

[0007] Preferably, the system also includes a servo motor, pulleys, a transmission belt, a first transmission shaft, and a take-up roller. The servo motor is fixedly connected to the outer side of the right bracket and is electrically connected to the controller. The pulleys include an upper pulley, a lower pulley, and a left pulley. The lower pulley is fixedly connected to the output shaft of the servo motor. The first transmission shaft is rotatably connected between the two brackets. The take-up roller is fixedly connected to the first transmission shaft. The upper pulley is fixedly connected to the right side of the first transmission shaft. The upper pulley and the lower pulley are connected by a transmission belt.

[0008] Preferably, the assembly also includes an inclined plate, a second drive shaft, a movable pressure roller, and an auxiliary pressure roller. Inclined plates are fixedly connected to the front sides of both supports, with the upper end of the inclined plate being higher than the lower end. The second drive shaft is rotatably connected to the upper part of the inclined plate, and a movable pressure roller is fixedly connected to the second drive shaft. An auxiliary pressure roller is rotatably connected to the upper part of the inclined plate, located below the movable pressure roller. A left pulley is fixedly connected to the right side of the second drive shaft. The upper pulley, lower pulley, and left pulley are coplanar and synchronously driven by the same drive belt, so that the winding roller and the movable pressure roller rotate in coordination, achieving stable conveying and tight winding of the excess material.

[0009] As a preferred option, anti-slip pads are symmetrically provided on both the front and back sides of the bottom of the base plate.

[0010] Preferably, the surface of the take-up roller is provided with anti-slip texture.

[0011] Preferably, the sponge pad is made of latex sponge.

[0012] The present invention has the following advantages: 1. The present invention, by setting up a collaborative structure of electric slide rail, electric slider and limiting plate, allows the controller to automatically adjust the distance between the two limiting plates, so as to achieve the effect of adaptive guidance and positioning of waterproof membrane scraps of different widths. This effectively avoids the problems of arbitrary operation, scrap offset and loose winding that exist when manually bundling, and improves the standardization and work efficiency of scrap collection.

[0013] 2. This utility model uses a servo motor to drive the lower pulley, and transmits the power synchronously to the upper pulley and the left pulley via a transmission belt. This drives the winding roller, the movable pressure roller and the auxiliary pressure roller to operate in coordination. Combined with the guide of the inclined plate and the support of the conveying roller, it achieves the effect of stable conveying and tight winding of the residual material. This solves the defects of traditional recycling methods, such as loose winding, bulging and loosening caused by asynchronous transmission or uneven pressure.

[0014] 3. This utility model uses a latex sponge pad on the top of the frame to buffer the impact of residual material on the edge of the equipment. At the same time, the anti-slip texture on the surface of the winding roller enhances the friction, and the anti-slip pad on the bottom of the base plate improves the stability of the whole machine. This achieves the effect of protecting the integrity of the material surface, preventing slippage and equipment slippage, and further ensuring the safety and reliability of the recycling process.

Detailed Implementation

[0021] Example: A device for recycling and winding residual waterproof membrane material, such as... Figure 1 and Figure 2 As shown, the system includes a base plate 1, a bracket 2, a controller 201, a frame 3, a sponge pad 301, an electric slide rail 4, an electric slider 5, a limit plate 6, and a conveyor roller 7. Two brackets 2 are screwed to the rear top of the base plate 1. Anti-slip pads are symmetrically provided on both the front and rear sides of the bottom of the base plate 1. The controller 201 is screwed to the outer side of the left bracket 2. The frame 3 is screwed to the front top of the base plate 1. Sponge pads 301, made of latex sponge, are provided on the front and rear edges of the top of the frame 3. Electric slide rails 4 are screwed to both the front and rear sides of the frame 3. The electric slide rails 4 are electrically connected to the controller 201. Two electric sliders 5 are slidably connected to each electric slide rail 4. The electric sliders 5 are electrically connected to the controller 201. Limit plates 6 are fixedly connected between corresponding electric sliders 5. Multiple conveyor rollers 7 are rotatably connected inside the frame 3 along its length.

[0022] like Figure 3 and Figure 4As shown, it also includes a servo motor 8, a pulley 9, a transmission belt 10, a first transmission shaft 11, and a take-up roller 12. The servo motor 8 is connected to the outside of the right bracket 2 by screws. The servo motor 8 is electrically connected to the controller 201. The pulley 9 includes an upper pulley 9, a lower pulley 9, and a left pulley 9. The lower pulley 9 is fixedly connected to the output shaft of the servo motor 8. The first transmission shaft 11 is rotatably connected between the two brackets 2. The take-up roller 12 is fixedly connected to the first transmission shaft 11. The surface of the take-up roller 12 is provided with anti-slip texture. The upper pulley 9 is fixedly connected to the right side of the first transmission shaft 11. The upper pulley 9 and the lower pulley 9 are connected by transmission belt 10.

[0023] like Figure 5 As shown, it also includes an inclined plate 13, a second drive shaft 14, a movable pressure roller 15, and an auxiliary pressure roller 16. The front sides of the two brackets 2 are each connected to an inclined plate 13 by screws. The upper end of the inclined plate 13 is higher than the lower end. The upper part of the inclined plate 13 is rotatably connected to the second drive shaft 14. The movable pressure roller 15 is fixedly connected to the second drive shaft 14. The upper part of the inclined plate 13 is rotatably connected to the auxiliary pressure roller 16 at the position below the movable pressure roller 15. The left pulley 9 is fixedly connected to the right side of the second drive shaft 14. The upper pulley 9, the lower pulley 9, and the left pulley 9 are all coplanar and synchronously driven by the same drive belt 10, so that the winding roller 12 and the movable pressure roller 15 keep rotating in coordination, realizing the stable conveying and tight winding of the excess material.

[0024] When this device is needed, the remaining waterproof membrane material to be recycled is first placed on the conveyor roller 7 inside the frame 3. The operator sets the width parameter of the remaining material through the controller 201. After receiving the instruction, the controller 201 automatically controls the electric slide rails 4 on both sides to start, driving the electric sliders 5 on them to slide along the guide rails. The corresponding electric sliders 5 on the front and rear are fixedly connected to the limit plates 6. The electric sliders 5 on both sides move towards each other or away from each other under the synchronous control of the controller 201. Adjusting the distance between the two limit plates 6 realizes automatic limit guidance for the remaining material of different widths, ensuring that the material does not shift or wrinkle during the conveying process. Then, the servo motor 8 is started, and its output shaft drives the lower pulley 9 to rotate. The power is transmitted to the upper pulley 9 and the left pulley 9 through the transmission belt 10, so that the first transmission shaft 11 drives the winding roller 12 to rotate. At the same time, the second transmission shaft 14 drives the movable pressure roller 15 to rotate, and cooperates with the auxiliary pressure roller 16 to apply pressure, so as to realize the stable conveying and tight winding of the remaining material.

[0025] As the take-up roller 12 continues to rotate, the excess waterproof membrane material is evenly wound around its surface. The anti-slip texture on the take-up roller 12 enhances friction, prevents slippage, and ensures tight winding. The inclined plate 13 is set at an angle to guide the excess material smoothly into the winding area. The movable pressure roller 15 and the auxiliary pressure roller 16 work together to prevent loosening or bulging during the winding process. The conveyor roller 7 is distributed along the length of the frame 3 to provide continuous support for the excess material, ensuring its smooth transition to the winding position. The entire transmission system is synchronously driven by the same transmission belt 10, ensuring coordinated operation of the take-up roller 12, movable pressure roller 15, and auxiliary pressure roller 16, thereby improving operational stability and roll quality.

[0026] During operation, the sponge pads 301 on the front and rear edges of the top of the frame 3 are made of latex sponge, which effectively buffers the impact between the excess material and the frame and prevents surface scratches, reducing operating noise. The bottom of the base plate 1 is symmetrically equipped with anti-slip pads on the front and rear sides to enhance the stability of the whole machine and prevent slippage and vibration. All actions are uniformly controlled by the controller 201, including the displacement of the electric slide rail 4 and the start and stop speed of the servo motor 8, to realize automated parameterized operation. When a roll is completed, the material is cut off and the bundle is removed to continue the next cycle.
