Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to an automatic cutting device for the production of modified bitumen flexible waterproof membrane. Background Technology

[0002] In today's booming construction industry, modified bitumen flexible waterproof membranes, as an important waterproofing material, are experiencing a continuous increase in market demand. Automatic cutting devices play a crucial role in their production process, directly impacting the quality of the finished membrane and production efficiency. Precise cutting ensures that the membrane dimensions are compliant, meeting the actual needs of various building waterproofing projects and improving the membrane's practicality and applicability. Highly efficient automatic cutting devices can also significantly shorten production cycles, reduce labor costs, and bring greater economic benefits to enterprises.

[0003] Currently, common automatic cutting devices for modified bitumen flexible waterproof membranes on the market mainly consist of a roll unwinding mechanism, a conveying mechanism, a cutting mechanism, and a rewinding mechanism. The roll is unwound from the unwinding mechanism, conveyed to the cutting mechanism via the conveying mechanism, and then collected by the rewinding mechanism after cutting. The conveying mechanism generally uses a traditional belt conveyor, relying on the friction between the belt and the roll to propel it forward. The cutting mechanism typically uses circular or flat blades to perform the cutting operation while the roll is moving at a constant speed. These devices achieve a certain degree of automated cutting of the roll, meeting basic production needs.

[0004] However, existing equipment has certain problems. During transportation, asphalt rolls are prone to deviating from their intended trajectory due to external factors. In actual production, issues such as core eccentricity and poor flatness of the roll itself can occur during unwinding, interfering with normal transportation. Once the roll deviates from its intended trajectory, its relative position to the cutting blade will also deviate, affecting the accuracy and quality of subsequent cutting. In severe cases, it may even lead to the scrapping of the roll, increasing production costs. Therefore, an automatic cutting device for the production of modified asphalt flexible waterproof rolls is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic cutting device for the production of modified bitumen flexible waterproof membrane, which aims to improve the problem that bitumen membranes are prone to deviating from the predetermined trajectory under the influence of external factors during transportation, thus affecting subsequent cutting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic cutting device for producing modified bitumen flexible waterproof membrane includes a cutting machine, a conveyor belt fixedly connected to the inner wall of the cutting machine, and a stabilizing component and an adjusting component provided on the outer wall of the conveyor belt.

[0008] The stabilizing component includes multiple rubber rollers located at the top of the conveyor belt. A fixed frame is fixedly connected to the inner wall of the cutting machine. Multiple telescopic cylinders are fixedly connected to the top of the fixed frame. A connecting frame is fixedly connected to the output end of each telescopic cylinder.

A connecting plate is fixedly connected to one side of each connecting block. Multiple sliding grooves are formed inside the connecting plate. Multiple connecting blocks are provided on the outer wall of the connecting plate. A sliding strip is fixedly connected to one side of each connecting block. The sliding strip is slidably connected to the inner wall of the sliding groove. A support frame is fixedly connected to the bottom of each connecting block. Each support frame is rotatably connected to the outer wall of the rubber roller.

[0009] As a further description of the above technical solution:

A limit strip is fixedly connected to the inner wall of the connecting frame, and the limit strip is slidably connected inside the connecting block.

[0012] The connecting frame is slidably connected inside the fixed frame, and the connecting plate is slidably connected inside the connecting frame.

[0013] As a further description of the above technical solution:

[0014] The stabilizing component includes multiple guide rollers located on one side of the conveyor belt, and fixed plates are fixedly connected to both sides of the conveyor belt.

[0015] As a further description of the above technical solution:

[0016] The fixed plate is slidably connected to a second connecting frame, and each second connecting frame is rotatably connected to both ends of the guide roller.

[0017] As a further description of the above technical solution:

[0018] A bidirectional cylinder is fixedly connected inside the support plate, and sliders are fixedly connected to both output ends of the bidirectional cylinder.

[0019] As a further description of the above technical solution:

[0022] Each of the transmission plates is rotatably connected to a fixed block, and a second connecting plate is fixedly connected to the top of the fixed block. The top of the second connecting plate is fixedly connected to the bottom of the second connecting frame.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the downward squeezing force and friction of the rubber rollers limit the movement direction of the asphalt roll material. At the same time, the movement of the rubber rollers is adjusted so that the rubber rollers are evenly distributed on the surface of the asphalt roll material, thereby achieving the effect of fixing the movement direction of the asphalt roll material. This solves the problem that asphalt roll material is prone to deviating from the predetermined trajectory under the influence of external factors during transportation, which affects subsequent cutting, and enhances the stability of the asphalt roll material during transportation.

[0025] 2. In this utility model, the sliders on both sides are driven by a bidirectional cylinder to slide in opposite directions inside the support plate, causing the guide roller to move up and down, thereby achieving the effect of adjusting the surface tension of the asphalt roll material. This solves the problem that it is difficult to adjust the surface tension of different asphalt roll materials during transportation, and enhances the applicability of the equipment.

[0032] 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.

[0033] Reference Figures 1-3 An embodiment of this utility model is provided: an automatic cutting device for producing modified bitumen flexible waterproof membrane, including a cutting machine 1, a conveyor belt 3 fixedly connected to the inner wall of the cutting machine 1, and a stabilizing component and an adjusting component provided on the outer wall of the conveyor belt 3.

[0034] The stabilizing components include multiple rubber rollers 12 located on top of the conveyor belt 3, providing good friction and support to ensure the stability of the asphalt roll during transportation. A fixing frame 4 is fixedly connected to the inner wall of the cutting machine 1, providing necessary support and stability for the entire structure. Multiple telescopic cylinders 5 are fixedly connected to the top of the fixing frame 4. These cylinders 5 function to achieve rapid and precise adjustment via air pressure control, ensuring the rubber rollers 12 can adapt to different transportation needs. A connecting frame 6 is fixedly connected to the output end of the telescopic cylinders 5, and an electric telescopic rod 13 is fixedly connected inside the connecting frame 6. The electric telescopic rod 13 is responsible for automated height adjustment, making operation more convenient. Each electric telescopic rod 13 has a connecting block 2 14 fixedly connected to its output end. A connecting plate 1 7 is fixedly connected to one side of the connecting block 2 14. The connecting plate 1 7 has multiple sliding grooves 8 inside. The design of these sliding grooves 8 allows the sliding strips 9 to move smoothly, further improving the flexibility of the component. Multiple connecting blocks 10 are provided on the outer wall of the connecting plate 1 7. A sliding strip 9 is fixedly connected to the side of each connecting block 10. The sliding strip 9 is slidably connected to the inner wall of the sliding groove 8, ensuring the relative movement between components. A support frame 11 is fixedly connected to the bottom of each connecting block 10. The function of the support frame 11 is to transmit force to the rubber roller 12 and enhance its load-bearing capacity. Each support frame 11 is rotatably connected to the outer wall of the rubber roller 12, providing the necessary rotational flexibility. A support plate 24 is fixedly connected to one side of the cutting machine 1. The function of the support plate 24 is to provide additional support for the entire cutting component and ensure its stable operation. A roll unwinding frame 2 is fixedly connected to one side of the support plate 24. The roll unwinding frame 2 is used to store and support the asphalt roll to be processed. The inner wall of the connecting frame 6 is fixedly connected to the limiting strip 15, which is slidably connected inside the connecting block 10, providing necessary restrictions on the movement of the component and ensuring that it operates within a reasonable range. The connecting frame 6 is slidably connected inside the fixed frame 4, realizing flexible movement of the structure. The connecting plate 7 is slidably connected inside the connecting frame 6, further increasing the adaptability and flexibility of the entire structure.

[0035] Specifically, during the transportation of asphalt rolls, the telescopic cylinder 5 is first activated, causing its output end to drive the connecting frame 6 to slide inside the fixed frame 4. This action moves the rubber roller 12 to the top area of ​​the asphalt roll. The rubber roller 12 has high friction characteristics, which effectively enhances the friction between it and the surface of the asphalt roll, thus effectively preventing the asphalt roll from shifting during transportation. Next, the operator activates the electric telescopic rod 13, using its output end to drive the connecting plate 7 on one side of the connecting block 14 to slide inside the connecting frame 6. During its movement, the connecting plate 7 pushes the connecting block 10 at one end of multiple sliding strips 9 along the outer wall of the limiting strip 15 via the sliding groove 8. In this way, the rubber roller 12 is evenly distributed on the surface of the asphalt roll, ensuring that the downward pressure and friction applied by the rubber roller 12 are evenly distributed across the entire surface of the asphalt roll, enhancing the stability of the asphalt roll during transportation, ensuring smooth transportation operations, and reducing the risks caused by shifting or sliding.

[0036] Reference Figure 1 and Figure 4 The stabilizing component includes multiple guide rollers 18, located on one side of the conveyor belt 3, responsible for guiding the stable operation of the asphalt roll and ensuring its smooth movement during transportation. Fixed plates 16 are fixedly connected to both sides of the conveyor belt 3. The fixed plates 16 provide support and a fixed foundation for the guide rollers 18 to ensure the stability of the entire system. Connecting frames 17 are slidably connected inside the fixed plates 16. The flexible sliding of the connecting frames 17 allows them to be adjusted according to actual needs to accommodate asphalt rolls of different widths. Each connecting frame 17 is rotatably connected to both ends of the guide roller 18. This structural design allows the guide roller 18 to rotate flexibly, thereby reducing friction and improving transportation efficiency. A bidirectional cylinder 23 is fixedly connected inside the support plate 24. The bidirectional cylinder 23 provides the necessary power to adjust the guide rollers 18 up and down to accommodate rolls of different specifications. Both output ends of the bidirectional cylinder 23 are fixedly connected to sliders 22, which are slidably connected inside the support plate 24, ensuring smooth and flexible movement. Each slider 22 is rotatably connected to a transmission plate 21. The design of the transmission plate 21 makes force transmission more efficient, thereby optimizing the overall motion mechanism. Each transmission plate 21 is rotatably connected to a fixing block 20, which provides a stable foundation for subsequent connections. A connecting plate 29 is fixedly connected to the top of the fixing block 20, and the top of the connecting plate 29 is fixedly connected to the bottom of the connecting frame 2 17.

[0037] Specifically, in adjusting the surface tension of the asphalt roll, the bidirectional cylinder 23 is first activated. The two ends of this cylinder drive the connected slider 22 to slide in opposite directions inside the support plate 24. As the slider 22 moves, it promotes the up-and-down movement of the fixed block 20 via the connected transmission plate 21. The up-and-down movement of the fixed block 20 further drives the movement inside the fixed plate 16 via the top connecting frame 17 of the connecting plate 19. At this time, the dynamic changes of the fixed block 20 directly affect the synchronous movement of the guide roller 18. By precisely adjusting the up-and-down position of the guide roller 18, the surface tension of the asphalt roll can be effectively adjusted. The smooth execution of this process facilitates subsequent cutting operations, ensuring the efficiency and accuracy of the entire production process.

[0038] Working principle: During the adjustment of the surface tension of the asphalt roll, the bidirectional cylinder 23 is activated. The output ends of the bidirectional cylinder 23 drive the sliders 22 on both sides to slide in opposite directions inside the support plate 24. While the sliders 22 are moving, they will push the fixed block 20 to move up and down through the transmission plate 21. While the fixed block 20 is moving, it will move up and down inside the fixed plate 16 through the connecting frame 17 at the top of the connecting plate 19, thereby pushing the guide roller 18 to move synchronously. By adjusting the up and down movement of the guide roller 18, the surface tension of the asphalt roll is adjusted, which facilitates subsequent cutting.

[0039] During the transportation of asphalt rolls, the output end of the telescopic cylinder 5 drives the connecting frame 6 to slide inside the fixed frame 4, causing the rubber roller 12 to move to the top of the asphalt roll. The high friction of the rubber roller 12 enhances the friction between it and the surface of the asphalt roll, preventing the asphalt roll from shifting during transportation. Next, the electric telescopic rod 13 is activated, and its output end drives the connecting plate 7 on one side of the connecting block 14 to slide inside the connecting frame 6. As the connecting plate 7 moves, it pushes the connecting blocks 10 at one end of multiple sliding strips 9 along the outer wall of the limiting strip 15 via the sliding groove 8. This ensures that the rubber roller 12 is evenly distributed on the surface of the asphalt roll, guaranteeing that the downward pressure and friction of the rubber roller 12 are evenly distributed on the surface, thus enhancing the stability of the asphalt roll during transportation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
