Description

Technical Field

[0001] This utility model belongs to the field of waterproof membrane production technology, specifically relating to a tape rack damper for a packing machine. Background Technology

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up to prevent leakage. As a leak-proof connection between the foundation and the building, they serve as the first line of defense for waterproofing the entire project, playing a crucial role. Existing asphalt-based waterproof membrane rolling and packaging systems consist of a frame, a rolling device for rolling the membrane, a cutting device for cutting the membrane, a tape-applying device for wrapping the finished membrane, and a pushing device for pushing the finished membrane out of the rolling device. In existing technology, the tape damper on the baling machine's tape rack is a clamping plate type. Each time the tape is changed, the baffle needs to be removed, the tape installed, and then the baffle and top screw reinstalled. The tape clamping plate and top screw loosen after every 2-3 rolls, requiring readjustment and tightening, severely impacting production efficiency. Summary of the Invention

[0003] To overcome the problems of inconvenient tape replacement and frequent adjustment of clamping in the prior art, which seriously affects production efficiency, this utility model provides a tape rack damper for a packaging machine. The tape is fixed by supporting the inner wall of the tape roller with the elastic force of the deformed elastic steel sheet 4, ensuring convenient and quick tape replacement, saving time and effort, and improving work efficiency. The clamping force of the spring 7 on the movable friction plate 6 can be changed by adjusting the nut 8, thereby changing the friction between the fixed friction plate 5 and the movable friction plate 6, ensuring that the tape roll has the required resistance during packaging. Because the spring 7 has a certain elastic extension and contraction, when the fixed friction plate 5 and the movable friction plate 6 wear, the spring 7 compensates by elastic deformation and elongation, ensuring the required friction force, extending the adjustment cycle, and ensuring work efficiency.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A damper for a baling machine tape frame mainly includes a spindle 1, a roller 2, a baffle 3, an elastic steel sheet 4, a fixed friction plate 5, a movable friction plate 6, a spring 7, and an adjusting nut 8. The spindle 1 includes an installation section 11, a support section 12, and a lead screw section 13. The spindle 1 is installed on the baling machine tape frame via the installation section 11 and bolts. The roller 2 has a hollow structure and is rotatably installed on the support section 12 via bearings. The elastic steel sheet 4 is installed on the curved surface of the roller 2 via screws. The fixed friction plate 5 is fixedly installed on the outer end face of the roller 2. The baffle 3 is installed on the other end face of the roller 2 via screws. The movable friction plate 6 is installed on the spindle 1 via splines. The spring 7 is fitted onto the lead screw section 13. The adjusting nut 8 is threadedly connected to the lead screw section 13. The two ends of the spring 7 are respectively supported on the movable friction plate 6 and the adjusting nut 8.

[0005] Furthermore, the outer end face of the roller 2 is provided with a groove, and the fixed friction plate 5 is embedded in the groove.

[0006] Furthermore, the elastic steel sheet 4 is provided with serrations 9 on both sides to increase the friction with the conveyor belt roller.

[0007] The beneficial effects of this utility model are: This invention utilizes the elastic force of a deformed elastic steel sheet to support the inner wall of the tape roller, thus fixing the tape in place. This ensures convenient and quick tape replacement, saving time and effort and improving work efficiency. By adjusting the nut, the clamping force of the spring on the movable friction plate can be changed, thereby altering the friction between the fixed and movable friction plates. This ensures the tape roll has the required resistance during packaging. Because the spring has a certain elastic extension and contraction, when the fixed and movable friction plates wear, the spring compensates by elastically deforming and elongating, ensuring the required friction, extending the adjustment cycle, and maintaining work efficiency.

[0012] This utility model discloses a damper for a strapping machine's tape frame. The damper mainly includes a spindle 1, a roller 2, a baffle 3, an elastic steel sheet 4, a fixed friction plate 5, a movable friction plate 6, a spring 7, and an adjusting nut 8. The spindle 1 includes an mounting section 11, a support section 12, and a lead screw section 13. The spindle 1 is mounted on the strapping machine's tape frame via the mounting section 11 and bolts. The roller 2 has a hollow structure and is rotatably mounted on the support section 12 via bearings. The elastic steel sheet 4 is mounted on the curved surface of the roller 2 via screws. The fixed friction plate 5 is fixedly mounted on the outer end face of the roller 2. The baffle 3 is mounted on the other end face of the roller 2 via screws. The movable friction plate 6 is mounted on the spindle 1 via a spline. The spring 7 is fitted onto the lead screw section 13. The adjusting nut 8 is connected to the lead screw section 13. The rod segment 13 is threaded, and the two ends of the spring 7 are supported on the movable friction plate 6 and the adjusting nut 8, respectively. When installing the tape, the tape roller is fitted onto the roller shaft 2. The tape roller compresses the elastic steel plate 4, causing the elastic steel plate 4 to bend and deform. The elastic force of the deformed elastic steel plate 4 supports the inner wall of the tape roller to achieve the installation and fixation of the tape, ensuring that the tape replacement is convenient and quick, saving time and effort, and improving work efficiency. The clamping force of the spring 7 on the movable friction plate 6 can be changed by adjusting the nut 8, thereby changing the friction force between the fixed friction plate 5 and the movable friction plate 6, ensuring that the tape roll has the required resistance during packaging. Because the spring 7 has a certain elastic extension and contraction, when the fixed friction plate 5 and the movable friction plate 6 wear, the spring 7 compensates by elastic deformation and elongation, ensuring the required friction force, extending the adjustment cycle, and ensuring work efficiency.

[0013] In this embodiment, the outer end face of the roller 2 is provided with a groove, and the fixed friction plate 5 is embedded in the groove.

[0014] In this embodiment, the elastic steel sheet 4 is provided with serrations 9 on both sides to increase the friction with the tape roller. The serrations 9 cut into the inner wall of the tape roller to prevent the tape roll from slipping out and ensure a secure installation.

[0015] Work process: When installing the tape, the tape roller is fitted onto the roller shaft 2. The tape roller compresses the elastic steel sheet 4, causing the elastic steel sheet 4 to bend and deform. The elastic force of the deformed elastic steel sheet 4 supports the inner wall of the tape roller, thus fixing the tape in place. This ensures that tape replacement is convenient and quick, saving time and effort and improving work efficiency. By adjusting the nut 8, the clamping force of the spring 7 on the movable friction plate 6 can be changed, thereby changing the friction between the fixed friction plate 5 and the movable friction plate 6. This ensures that the tape roll has the required resistance during packaging. Because the spring 7 has a certain amount of elastic extension and contraction, when the fixed friction plate 5 and the movable friction plate 6 wear, the spring 7 compensates by elastically deforming and elongating, ensuring the required friction, extending the adjustment cycle, and ensuring work efficiency.

[0016] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
