Detailed Implementation

[0017] A dual-airbag, four-scraper clamp, such as Figure 1-4 As shown, the fixture includes an upper pressure plate 1, a scraper bracket 2, a pivot 3, an airbag 4, a hinge buckle 5, and a lower pressure plate 6. The scraper bracket 2 is fixedly installed on the lower surface of the upper pressure plate 1. The scraper bracket 2 is rotatably connected to the lower pressure plate 6 via the pivot 3 and the hinge buckle 5 connected to the pivot 3. The airbag 4 is located between the lower pressure plate 6 and the scraper bracket 2. The airbag 4 includes a first airbag 41 and a second airbag 42, which are located on both sides of the pivot 3. The scraper bracket 2 has a first bracket 21, a second bracket 22, and a Z-shaped pressure plate 23. Both the first bracket 21 and the second bracket 22 are made of stamped and bent metal plates. The first bracket 21 includes a first base plate 211, a scraper seat 212 located at the front end of the first base plate 211, and vertical baffles 213 located on both sides of the first base plate 211. The second bracket 22 includes a second base plate 221 and side baffles 222 located on both sides of the second base plate 221. The upper pressure plate 1, the first base plate 211, and the second base plate 221 are sequentially attached and riveted together with rivets 7. Multiple scraper supports 2 are provided, all of which are connected in series via a pivot 3 and fixed at equal intervals to the upper pressure plate 1. Simultaneously, three hinge buckles 5 are symmetrically connected in series on the pivot 3, respectively positioned between two adjacent scraper supports 2 at both ends of the pivot 3, and between two adjacent scraper supports 2 in the middle.

[0018] This utility model replaces the original cast bracket with a sheet metal processing assembly bracket. The first and second brackets are formed by stamping and bending metal plates, and the first and second brackets are anchored to the lower pressure plate with rivets. This makes processing convenient, improves product precision, and reduces costs. During product upgrades and use, the product has strong plasticity and low maintenance and replacement costs.

[0019] Preferably, the scraper holder 212 is a U-shaped structure formed by punching and bending the front end of the first base plate 211. A limiting through hole 214 is provided on the side wall connecting the scraper holder 212 to the first base plate 211, and the end face of the other side wall is lower than the lower surface of the first base plate 211. A protruding post 215 is provided on the bottom wall of the scraper holder 212. The vertical baffle 213 is formed by partially cutting and vertically bending both sides of the first base plate 211. Riveting holes are opened in the middle of both the front and rear ends of the first base plate 211. The two sides of the second base plate 221 are vertically bent to form side baffles 222, and the two side baffles 222 together with the base plate form a U-shaped groove structure. A shaft hole 223 is provided on the middle section of the side baffle 222, and the pivot 3 passes through the shaft hole 223. The side baffle 222 has outwardly turned flaps 224 formed by punching and bending in front of and behind the shaft hole 223. The flaps 224 at the front end of the side baffle 222 have a slot 225. The second base plate 221 is stacked on the lower surface of the first baffle, with its front end close to the scraper seat 212. The vertical baffle 213 can be precisely locked in the slot 225. The second base plate 221 also has rivet holes at the two rivet holes of the first baffle. The front ends of the side baffles 222 on both sides of the second base plate 221 have arc-shaped grooves 227. The rear ends of the second base plate 221 have punched holes. The punched holes separate the ends of the side baffles 222 on both sides to form a connecting piece 226. The connecting piece 226 is bent and protrudes towards the surface where the flaps 224 are located. One end of the Z-shaped pressure plate 23 is located below the scraper seat 212, and the other end is attached to the lower front surface of the second base plate 221. The Z-shaped pressure plate 23 also has a riveting hole corresponding to the riveting hole at the front end of the first base plate 211. The Z-shaped pressure plate 23 is riveted and fixed to the second base plate 221, the first base plate 211, and the upper pressure plate 1 by rivets 7. The hinge buckle 5 has a U-shaped plate structure. The two side plates of the hinge buckle 5 have through holes, and the bottom plate of the hinge buckle 5 has a threaded hole. The pivot 3 passes through the through hole. The lower pressure plate 6 is attached to the bottom plate of the hinge buckle 5. The lower pressure plate 6 has a through hole corresponding to the threaded hole. The lower pressure plate 6 and the hinge buckle 5 are fixedly connected by bolts passing through the through hole and the threaded hole. The rear end of the pressure plate 6 is vertically bent to block and limit the rear end of the second airbag 42. The front end of the pressure plate 6 is obtusely bent to limit the first airbag 41. The front end face of the pressure plate 6 is close to the vertical baffle 213.

[0020] In practical use, the scraper's rear end is positioned at the gap between the upper pressure plate and the scraper seat. A limiting through hole is provided on the U-shaped scraper seat, facilitating the insertion of the scraper's rear end into the through hole and creating left and right limiting for the scraper's rear end. The protruding post facilitates positioning of the lower end of the spring, forming an elastic pressure on the scraper thickness. This allows the scraper to elastically contact the roller surface during use, and also improves the scraper's pressure on the roller surface, making it easier to clean debris from the roller surface. The U-shaped groove design and outward flange design of the second bracket can limit and protect the airbag. The obtuse angle bending structure of the lower pressure plate and the bent protruding connecting piece design of the second base plate can effectively improve the unloading efficiency of the first airbag on the scraper blade and the loading efficiency of the second airbag on the scraper blade.

[0021] This utility model is not limited to the specific embodiments described above. For those skilled in the art, all modifications made based on the above concept without creative effort fall within the protection scope of this utility model.
