Description

Technical Field

[0001] This utility model relates to the field of waterproof membranes, and in particular to an active feeding device for the base fabric of modified bitumen waterproof membranes. Background Technology

[0002] Existing modified bitumen waterproofing production lines have a high level of automation, basically covering processes such as automatic feeding, base fabric feeding, storage, drying, traction, pre-impregnation, impregnation coating, film / sand coating, cooling, storage, rolling, and weighing. The entire process is largely automated. The base fabric of modified bitumen waterproofing membranes is generally polyester filament base fabric. On existing production lines, after the base fabric is fed, before the pre-impregnation process, there is a traction device to transport the base fabric to the impregnation section for covering with modified bitumen. However, in the base fabric feeding, storage, and drying stages, although there is no ambient temperature traction and transportation, this section of the production line is still very long, which can easily cause the polyester filament base fabric to be slightly stretched in the longitudinal direction. As a result, even after the product is impregnated with modified bitumen and cooled and shaped, the pre-stretched base fabric is shaped into a slightly stretched state by the entire production line. This slight stretch of only about 1% will cause a 1cm shrinkage seam at the longitudinal overlap of the membrane after use, increasing the risk of water seepage and leakage. Utility Model Content

[0003] To address the problem of stretching of the base fabric caused by traction equipment in existing technologies, this utility model provides an active feeding device for the base fabric of modified bitumen waterproof membrane.

[0008] Furthermore, the locking structure includes a rotating shaft frame, a threaded post, and a locking nut; a locking plate is welded to the outer side wall of the upper cover; a rotating shaft frame is welded to the top of the bottom plate; a threaded post is rotatably connected inside the rotating shaft frame; a locking nut is threaded to the outer side wall of the threaded post; a locking groove is formed on the outer side wall of the locking plate, and the threaded post can be rotated and embedded into the locking groove, and locking is achieved by tightening the locking nut;

[0009] Furthermore, the drive device includes a driven gear, a mounting bracket, a motor, and a driving gear; the driven gear is detachably connected to the outer side wall of the fixed shaft; the mounting bracket is bolted to the outer side wall of the frame; the motor is bolted to the outer side wall of the mounting bracket; the driving gear is detachably mounted to the output end of the motor; the driving gear and the driven gear mesh with each other.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] This invention achieves active feeding of the base fabric from the source by adding an active rotating feeding wheel to the original base fabric feeding center shaft; the feeding shaft is driven to rotate actively by a drive device, no longer relying on the hard pulling of subsequent equipment, thereby reducing the pre-tension caused by passive traction force; from the moment the base fabric begins to be fed, the generation of micro-stretching is avoided, fundamentally solving the problem of longitudinal shrinkage of the roll material caused by micro-stretching.

[0014] The drive unit uses a servo motor, and the operator can precisely adjust the motor speed and direction through the control panel. This allows the rotation speed of the feeding shaft to be precisely controlled according to actual production needs, thereby ensuring that the tension of the base fabric is uniform and stable during the conveying process.

[0028] The implementation principle of this utility model embodiment is as follows:

[0029] First, the staff adjusts the fixing device 4 of the feeding shaft 3 according to the size specifications of the tire base fabric shaft. Then, the upper cover 43 of the fixing device 4 is opened, rotating around the support groove 41 via a hinge to expose the upper roller 44 and lower roller 42 inside. The tire base fabric shaft is installed onto the feeding shaft 3, ensuring accurate alignment of the fixing shafts 31 at both ends of the feeding shaft 3. One fixing shaft 31 is placed inside the rotating bracket 2, which is welded to the top of the frame 1, providing stable and rotatable support for the feeding shaft 3. The other fixing shaft 31 is placed into the support groove 41 of the fixing device 4. Next, the upper cover 43 is closed, causing the upper roller 44 and lower roller 42 to tightly clamp the fixing shaft 31. Then, the locking structure is operated, rotating the threaded post 61 inside the rotating shaft bracket 6 into the locking groove of the locking plate 45, and tightening the locking nut 62 to ensure that the upper cover 43 and the base plate 40 are firmly locked, thereby stabilizing the tire base fabric shaft.

[0030] The operator turns on the control panel 7. On the display screen of the control panel 7, the initial status information of the motor 53 can be seen. By using the knobs and buttons on the control panel 7, the speed, direction and other parameters of the servo motor 53 can be precisely set according to the production process requirements. For example, according to the production speed of the subsequent process, a suitable fabric feeding speed can be set to ensure that the base fabric is conveyed at a uniform speed. After the setting is completed, the equipment enters the standby state.

[0031] Press the start button on the control panel 7, and the servo motor 53 starts running; the drive gear 54 at the output end of the motor 53 rotates accordingly. Since the drive gear 54 and the driven gear 5, which is detachably connected to the outer wall of the fixed shaft 31, mesh with each other, the rotation of the drive gear 54 drives the driven gear 5 to rotate, thereby causing the feeding shaft 3 to start rotating actively; the active rotation of the feeding shaft 3 provides the driving force for the conveying of the base fabric, avoiding the problems caused by the hard pulling and rotation in the traditional method; as the feeding shaft 3 rotates, the base fabric shaft installed on the feeding shaft 3 also rotates synchronously, and begins to release the fabric at a uniform speed; the spring 33 welded to the outer wall of the inner rib 32 is connected to the protrusion 34, which passes through the feeding shaft 3 and has anti-slip texture on the outside; during the fabric release process, the protrusion 34 is in close contact with the base fabric shaft, and the anti-slip texture increases the friction between the two, ensuring that the base fabric shaft can rotate stably with the feeding shaft 3, achieving uniform fabric release; and preventing the base fabric from being deformed by sudden tension.
