[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] Reference Figures 1 to 3 In one embodiment of the present invention, the flipping device includes a first crossbeam 1 and a second crossbeam 2 pivotally connected, and a driving member 3 for driving the second crossbeam 2 to flip relative to the first crossbeam 1. One end of the driving member 3 is connected to the first crossbeam 1 and the other end is connected to the second crossbeam 2. When the driving member 3 drives the second crossbeam 2 to flip, so that the first crossbeam 1 and the second crossbeam 2 are in a closed state, the first crossbeam 1 and the second crossbeam 2 cooperate to form a receiving space 4, and the driving member 3 is received in the receiving space 4.

[0031] In this embodiment, the drive component 3 is telescopic. When the drive component 3 is extended, it drives the second crossbeam 2 to flip. Specifically, the drive component 3 can be a pneumatic cylinder or a hydraulic cylinder, etc. The cylinder body of the drive component 3 can be connected to the first crossbeam 1, and the telescopic rod of the drive component 3 can be connected to the second crossbeam 2. When the telescopic rod of the drive component 3 extends, it drives the second crossbeam 2 to flip, so that the first crossbeam 1 and the second crossbeam 2 are in an open state; when the telescopic rod of the drive component 3 retracts, it drives the second crossbeam 2 to flip, so that the first crossbeam 1 and the second crossbeam 2 are in a closed state.

[0032] Reference Figure 3 and Figure 4 Specifically, a first receiving groove 11 is provided in the first crossbeam 1, and a second receiving groove 21 is provided in the second crossbeam 2. When the first crossbeam 1 and the second crossbeam 2 are in a closed state, the first receiving groove 11 and the second receiving groove 21 are connected to form a receiving space 4. In this embodiment, when the first crossbeam 1 and the second crossbeam 2 are in a closed state, the openings of the first receiving groove 11 and the second receiving groove 21 are connected to form the receiving space 4. By housing the driving component 3 within the receiving space 4, the internal space of the first crossbeam 1 and the second crossbeam 2 is effectively utilized, reducing the space occupied by the driving component 3 on the overall space of the flipping device, thereby ensuring the compactness of the flipping device structure.

[0033] Reference Figure 4The two ends of the driving component 3 are respectively connected to the inner walls of the first receiving groove 11 and the second receiving groove 21. When the first crossbeam 1 and the second crossbeam 2 are in a closed state, the central axis of the driving component 3 is inclined relative to the extension direction of the first crossbeam 1 or the second crossbeam 2, and the shape of the receiving space 4 is correspondingly inclined. In this embodiment, the cross-sectional shape of the receiving space 4 is approximately as follows: Figure 4 The parallelogram shown is adapted to accommodate the inclined drive unit 3.

[0034] It is understood that in other embodiments, the shape of the receiving space 4 may also be rectangular or other shapes, as long as it has a volume that can accommodate the driving member 3. The above is only an exemplary description of the shape of the receiving space 4, and this application does not impose any specific limitations on it.

[0035] Reference Figure 4 The first receiving groove 11 is located away from the pivot connection end of the first crossbeam 1, and the second receiving groove 21 is located near the pivot connection end of the second crossbeam 2. The connection position of the driving member 3 with the first crossbeam 1 is away from the pivot connection ends of the first crossbeam 1 and the second crossbeam 2, and the connection position of the driving member 3 with the second crossbeam 2 is close to the pivot connection ends of the first crossbeam 1 and the second crossbeam 2, so as to drive the first crossbeam 1 and the second crossbeam 2 to rotate. Therefore, the positions of the first receiving groove 11 and the second receiving groove 21 are correspondingly matched with the position of the driving member 3 to ensure the compactness of the rotating device structure.

[0036] Reference Figure 4 The flipping device in this embodiment also includes a fixing frame 5 installed on the first crossbeam 1, the fixing frame 5 being away from the pivot connection end of the first crossbeam 1; one of the fixing frame 5 or the second crossbeam 2 is provided with a locking member 6, and the other is provided with a cooperating member 7; when the first crossbeam 1 and the second crossbeam 2 are in a closed state, the locking member 6 can cooperate with the cooperating member 7 to lock the relative position of the first crossbeam 1 and the second crossbeam 2.

[0037] In the accompanying drawings of this embodiment, the example shown is that the locking member 6 is installed on the fixing frame 5 and the mating member 7 is installed on the second crossbeam 2. This is not a limitation on the installation position of the locking member 6 and the mating member 7. In other embodiments, the locking member 6 may also be installed on the second crossbeam 2 and the mating member 7 may also be installed on the fixing frame 5.

[0038] Reference Figure 4 and Figure 5The locking component 6 includes a retractable locking shaft 61, and the mating component 7 includes a first cylindrical body 71 with an insertion slot, into which the locking shaft 61 can be inserted. When the driving component 3 drives the second crossbeam 2 to rotate, causing the first crossbeam 1 and the second crossbeam 2 to be in a closed state, the locking shaft can extend into the insertion slot of the first cylindrical body 71 to lock the relative positions of the first crossbeam 1 and the second crossbeam 2. Specifically, the locking component 6 may also include a driving cylinder for driving the retractable movement of the locking shaft 61. It can be understood that when the locking shaft 61 moves away from the insertion slot of the first cylindrical body 71, the driving component 3 can drive the second crossbeam 2 to rotate, causing the first crossbeam 1 and the second crossbeam 2 to be in an open state.

[0039] Reference Figure 5 In one optional embodiment, the flipping device further includes a second cylinder 62, and a locking shaft 61 is slidably inserted within the second cylinder 62. The second cylinder 62 supports the locking shaft 61 and is used to bear force to ensure a locking effect between the first crossbeam 1 and the second crossbeam 2.

[0040] Reference Figure 5 In one optional embodiment, a tapered guide surface 63 is provided on the side of the locking shaft 61 near the first cylinder 71. The tapered guide surface 63 guides the locking shaft 61 to be inserted into the insertion groove of the first cylinder 71.

[0041] Reference Figure 4 and Figure 5 In this embodiment, an elastic buffer layer 8 is provided on the closed contact surface of the first crossbeam 1 and / or the second crossbeam 2. The elastic buffer layer 8 can be installed on the first crossbeam 1 or the second crossbeam 2, and this application does not specifically limit this. The elastic buffer layer 8 can be configured as an elastic pad, such as a rubber block. When the driving member 3 drives the second crossbeam 2 to rotate, causing the first crossbeam 1 and the second crossbeam 2 to be in a closed state, the elastic buffer layer 8 can restrict the second crossbeam 2 from continuing to rotate and provide a certain buffering effect, thereby reducing the probability that the driving member 3 may be damaged by compression. When the second crossbeam 2 rotates to the point where the elastic buffer layer 8 is compressed, the locking member 6 and the mating member 7 can cooperate to lock the first crossbeam 1 and the second crossbeam 2 in the closed position.

[0042] Reference Figure 1 and Figure 2The flipping device of this embodiment can be used in weighing equipment for weighing and packaging various bagged products. This embodiment uses its application to the weighing and packaging of ton bags as an example for illustrative purposes. Based on this, the flipping device of this embodiment includes a pair of parallel first crossbeams 1 and a pair of parallel second crossbeams 2. The pair of first crossbeams 1 are relatively fixed to form a first crossbeam frame, and the pair of second crossbeams 2 are relatively fixed to form a second crossbeam frame. A feeding pipe 9 is installed on the first crossbeam frame, and a bag-expanding unit 10 is installed on the second crossbeam frame. When the first crossbeams 1 and second crossbeams 2 are in a closed state, the bag-expanding unit 10 cooperates with the feeding pipe 9, thus allowing material to be loaded through the feeding pipe 9.

[0043] Reference Figure 1 and Figure 2 Specifically, the bag expansion unit 10 is used to fix and expand the bag opening of the ton bag. When the first crossbeam 1 and the second crossbeam 2 are in a closed state, the bag expansion unit 10 cooperates with the discharge pipe 9 to allow the material to be transported into the ton bag through the discharge pipe 9 to complete the filling work.

[0044] One embodiment of this utility model also discloses a weighing device, including the aforementioned tilting device. It is understood that in the weighing device equipped with the aforementioned tilting device, when the driving member 3 drives the second crossbeam 2 to tilt, causing the first crossbeam 1 and the second crossbeam 2 to be in a closed state, the first crossbeam 1 and the second crossbeam 2 cooperate to form a receiving space 4, and the driving member 3 is received within the receiving space 4. Therefore, it effectively utilizes the internal space of the first crossbeam 1 and the second crossbeam 2, reduces the space occupied by the driving member 3 on the overall tilting device, and thus further ensures the compactness of the weighing device structure.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
