[0034] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0035] An embodiment of the utility model provides a belt tensioning device for a baling and forming machine, which can be used to bundle finely chopped straw, wherein the baling and forming machine includes a frame 4.

[0036] like Figure 1 and Figure 2 As shown, the belt tensioning device of this embodiment mainly includes a roller assembly 1 and a power assembly 2.

[0037] The roller assembly 1 includes a drum frame 11 and a roller 10 rotatably mounted on the drum frame 11 . The roller 10 is used to support the belt 5 . The drum frame 11 is rotatably mounted on the frame 4 via a rotating shaft 13 .

[0038] The power assembly 2 includes an elastic member 20, a fixed member 21, and a movable member. The first end of the elastic member 20 is connected to the drum frame 11, and the fixed member 21 is fixed to the frame 4. The movable member is mounted on the fixed member 21 and connected to the second end of the elastic member 20. The movable member can move relative to the fixed member 21 to stretch or release the elastic member 20, thereby driving the drum frame 11 to rotate about the axis of the rotating shaft 13 through the elastic member 20 to tighten or loosen the belt 5.

[0039] For example, the movable part can move in a first direction relative to the fixed part 21 to stretch the belt 5, thereby driving the drum frame 11 to rotate clockwise to tighten the belt 5; the movable part can move in a second direction relative to the fixed part 21 to loosen the belt 5, thereby driving the drum frame 11 to rotate counterclockwise to loosen the belt 5.

[0040] In the belt tensioning device of this embodiment, the movable part is connected to the drum frame 11 via an elastic member 20. In this way, the movable part moves relative to the fixed member 21 to stretch or release the elastic member 20, and then the elastic member 20 drives the drum frame 11 to rotate around the axis of the rotating shaft 13 to tighten or loosen the belt 5. The elastic member 20 can ensure that the belt 5 has an appropriate tension so as to bundle different materials.

[0041] like Figure 1 As shown, in some embodiments, the drum frame 11 of the roller assembly 1 may include a first side plate 111 and a second side plate 112, and the roller 10 is rotatably disposed between the first side plate 111 and the second side plate 112. The first side plate 111 and the second side plate 112 are rotatably connected to the frame 4 via a rotating shaft 13.

[0042] There are two groups of power assemblies 2, wherein the first end of the elastic member 20 in one group of power assemblies 2 is connected to the first side plate 111, and the first end of the elastic member 20 in the other group of power assemblies 2 is connected to the second side plate 112. By providing two groups of power assemblies 2, the stability of the rotation of the drum frame 11 can be ensured.

[0043] like Figure 1 As shown, there can be at least two elastic members 20 in each power assembly 2 , and the first ends of the at least two elastic members 20 are connected through a first connecting plate 25 , and the second ends are connected through a second connecting plate 22 .

[0044] In this embodiment, the first connecting plate 25 can form the first ends of at least two elastic members 20, and the second connecting plate 22 can form the second ends of at least two elastic members 20. The first connecting plate 25 can be fixed to the corresponding side plate, and the movable component can be connected to the second connecting plate 22. Providing at least two elastic members 20 can ensure that the belt 5 has sufficient tension.

[0045] Preferably, the elastic member 20 of this embodiment may be a spring.

[0046] like Figure 1 and Figure 2 As shown, in some embodiments, the fixing member 21 may be provided with a through hole. The movable components include a bolt 24 and a nut 23. The bolt 24 passes through the through hole and is connected to the second end of the elastic member 20. The nut 23 is connected to the bolt 24 and abuts against the fixing member 21. Under the elastic force exerted by the elastic member 20, the bolt 24 can be moved along its axial direction by rotating the nut 23, thereby adjusting the elastic force of the elastic member 20.

[0047] The shape of the fixing member 21 of the present invention is not specifically limited. Figure 1 and Figure 2 As shown, in some embodiments, the fixing member 21 can be a plate structure.

[0048] The fixing member 21 includes a bottom plate portion (not shown) and side plates (not shown) located on opposite sides of the bottom plate portion, with the side plates and the bottom plate portion forming an obtuse angle. One of the side plates can be connected to the frame 4 to secure the fixing member 21 to the frame 4.

[0049] The through hole on the fixing member 21 can be located on the bottom plate portion, the bottom plate portion is perpendicular to the bolt 24, the end of the bolt 24 connected to the elastic member 20 is located on one side of the bottom plate portion, and the nut 23 is located on the other side of the bottom plate portion, so that the nut 23 can be abutted against the bottom plate portion, and the bolt 24 can be moved along its axial direction by rotating the nut 23.

[0050] In one embodiment, the fixing member 21 may be fixed to the frame 4 by welding, thereby ensuring the stability of the fixing member 21 on the frame 4 .

[0051] like Figure 2 and Figure 3 As shown, in some embodiments, the belt 5 tensioning device may further include a scraper assembly 3, which is disposed on the drum frame 11 and contacts a side of the belt 5 for conveying materials, thereby scraping off the materials coated on the belt 5.

[0052] like Figure 3 As shown, in some embodiments, the scraper assembly 3 may include a first scraper 31 and a second scraper 32 arranged in a V-shape and a beam plate 33 connecting the two scrapers.

[0053] The first scraper 31 and the second scraper 32 are both in the shape of long strips. The beam plate 33 is connected to the top of the two scrapers respectively. The bottom of the two scrapers is used to contact the surface of the belt 5 to scrape off the materials.

[0054] Furthermore, in some embodiments, a first rib 35 is connected to each end of the beam plate 33, and a second rib 12 is provided on the drum frame 11. The first rib 35 and the second rib 12 are rotatably connected by a pin shaft, so that the scraper assembly 3 can rotate relative to the drum frame 11.

[0055] In some embodiments, the scraper assembly 3 also includes a pressure plate 34 connected to the beam plate 33. The pressure plate 34 extends along the opening direction of the two scrapers. By applying external force to the pressure plate 34, the scraper assembly 3 can be driven to rotate downward or upward relative to the drum frame 11 to increase the contact force between the two scrapers and the belt 5.

[0056] The embodiment of the present invention further provides a baling and forming machine, which can be used to bundle finely chopped straw. The baling and forming machine includes a frame 4 and a belt tensioning device as described in any one of the above embodiments.

[0057] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Furthermore, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
