BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is the front view of the horizontal tension roller pneumatic scraper device.

[0012] Figure 2 for Figure 1 A partial enlarged view of the middle S region.

[0013] Figure 3 It is a side view of the horizontal tension roller pneumatic scraper device. DETAILED DESCRIPTION

[0014] The utility model provides a horizontal tension roller pneumatic scraper device. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0015] See also Figures 1 to 3 The utility model provides a horizontal tension roller pneumatic scraper device. The attached figure is a simplified structural diagram, which is only used to explain the structural principle and is not proportional to the actual product. The attached figure only shows the structure related to the invention point of the application, and some conventional structures are not specifically drawn. Figure 3 Some internal structures (such as the shaft head, push rod, etc.) are drawn directly with solid lines. In fact, these internal structures cannot be directly observed from the outside.

[0016] The horizontal tension roller pneumatic scraper device comprises a scraper blade 11, a scraper clamp 12, a scraper top plate 13, and a scraper frame 30, wherein the scraper top plate is connected to the scraper frame. The scraper frame is provided with a pivot 31, and an axis head 38 is provided at each end of the scraper frame, and each axis head is connected to a support 39, wherein one of the supports is provided with a pneumatic oscillator 7. The scraper clamp and the scraper top plate are used to clamp the scraper blade. The scraper frame is used to support structures such as the scraper blade 11, the scraper clamp 12, and the scraper top plate 13. The significance of setting the vertical axis is to set the scraper frame to a suitable angle during assembly, that is, to set the scraper blade to a suitable angle.

[0017] Furthermore, an airbag bracket 20 is provided on the scraper frame, and the scraper top plate is provided on the airbag bracket; a scraper pressurizing airbag 21 and a scraper unloading airbag 22 are provided on the airbag bracket. The scraper pressurizing airbag and the scraper unloading airbag are provided to facilitate pressurizing or unloading pressure on the scraper during operation. For example, the scraper pressurizing airbag is inflated and expanded, and the scraper unloading airbag is deflated and contracted. At this time, the scraper top plate and the front end of the scraper blade are lowered, and the scraper blade and the roller surface of the horizontal tensioning roller fit more tightly. Conversely, the scraper pressurizing airbag is deflated and contracted, and the scraper unloading airbag is inflated and expanded. At this time, the scraper top plate and the front end of the scraper blade are raised, and the scraper blade and the roller surface of the horizontal tensioning roller fit more tightly. It can be seen that by providing the scraper pressurizing airbag and the scraper unloading airbag, it is convenient to adjust the degree of fit between the scraper and the roller surface online to ensure the cleaning effect.

[0018] Furthermore, the pneumatic oscillator is arranged on an oscillator bracket 70, which is connected to the bracket 39 on the same side; the output end of the oscillator is connected to a push rod 5 through a universal coupling 6, and the push rod is against the shaft head 38 on the same side. For ease of understanding, the air intake pipe and exhaust pipe of the pneumatic oscillator are also schematically drawn in the figure. When the pneumatic oscillator is working, the power is transmitted to the bracket through the universal coupling and the push rod, so that the bracket and the blade can reciprocate within a certain range when working, further providing a cleaning effect.

[0019] The two ends of the pivot are respectively provided with bearing seats 32. This arrangement facilitates the actual installation of the horizontal tension roller pneumatic scraper device.

[0020] Preferably, the scraper top plate is a carbon fiber plate. The scraper blade is preferably a stainless steel scraper blade. This arrangement ensures that the scraper top plate and the scraper blade have sufficient mechanical strength and can adapt to harsh working environments.

[0021] In actual application, the horizontal tension roller pneumatic scraper device is installed on the frames on both sides of the horizontal tension roller 9 (the frames are not shown in the attached figure), and the pneumatic oscillator is connected to the compressed air source of the factory. During the production process, the scraper clamp is not easy to deform, and the scraper blade can fit the roller surface well, which effectively solves the problems of slurry wrapped around the roller surface and slurry accumulation in the scraper. In addition, the horizontal tension roller pneumatic scraper device has a simple structure, and the original scraper blade can be used during the modification, without the need to customize the scraper blade.

[0022] It should be noted that, for ease of understanding, the accompanying drawings show a horizontal tensioning roller 9 , but the horizontal tensioning roller 9 itself is not outside the protection scope of the present application.

[0023] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
