[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1: Reference Figure 1-4The feeding mechanism for a bagging machine shown includes a pair of support frames 1. A slot 2 is formed on the inner side of each support frame 1. An installation roller 4 is slidably connected to the inner wall of the slot 2. A groove 13 is formed on the outer side of the installation roller 4. A positioning plate 10 is fixedly connected to the side of each support frame 1. A fixed cylinder 12 is fixedly connected to the bottom of the positioning plate 10. A sliding block 19 is slidably connected to the inner wall of the fixed cylinder 12. A clamping block 20, adapted to the groove 13, is fixedly connected to the bottom of the sliding block 19. A spring 16 is fixedly connected to the inner wall of the fixed cylinder 12. The two ends of the spring 16 are fixedly connected to the inner wall of the fixed cylinder 12 and the sliding block 19, respectively. A triangular block 11 is fixedly connected to the side of the sliding block 19. A sliding groove adapted to the triangular block 11 is formed on the outer side of the fixed cylinder 12. A pushing assembly is provided on the outer side of each support frame 1. The pushing assembly includes components fixedly connected to the side of each support frame 1. A fixed plate 5 is fixedly connected to a hydraulic push rod 6 on its side. A connecting block 7 is fixedly connected to the output end of the hydraulic push rod 6. A push frame 8 adapted to the installation roller 4 is fixedly connected to the outer side of the connecting block 7, which facilitates the installation and replacement of the installation roller 4. A push rod 9 is fixedly connected to the outer side of the push frame 8. The end of the push rod 9 away from the push frame 8 is set with an arc surface, which facilitates the push rod 9 to push the inclined surface of the triangular block 11. A sliding groove 14 is opened on the outer side of the installation roller 4. A guide rail 3 adapted to the sliding groove 14 is fixedly connected to the inner wall side of the empty groove 2 to prevent the installation roller 4 from deviating during the sliding process. A placement groove 17 is opened on the outer side of the guide rail 3. A protrusion 15 is fixedly connected to the inner wall side of the placement groove 17. The protrusion 15 is made of rubber block. The protrusion 15 has deformable ability, which can limit the installation roller 4 while not hindering the movement of the installation roller 4.

[0024] In this embodiment, the mounting roller 4 is placed in the empty groove 2. The hydraulic push rod 6 is controlled to drive the connecting block 7, the push frame 8, and the push rod 9 to move. The push frame 8 pushes the mounting roller 4 to slide along the guide rail 3 until the mounting roller 4 moves to the position where it abuts against the protrusion 15. During the movement, the push rod 9 squeezes the inclined surface of the triangular block 11. The triangular block 11 drives the sliding block 19 and the clamping block 20 to move upward. After pushing the mounting roller 4 to the appropriate position, the hydraulic push rod 6 is controlled to reset. The sliding block 19 is reset under the action of the spring 16. The clamping block 20 engages with the groove 13 to limit the mounting roller 4. Then, the mounting roller 4 is connected to the motor set outside. When the mounting roller 4 needs to be replaced, the new mounting roller 4 is placed in the empty groove 2. By performing the same operation on the mounting roller 4, the mounting roller 4 pushes out the original mounting roller 4, thus realizing the installation of the new mounting roller 4.

[0025] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment also proposes that the inclined surface of the triangular block 11 faces one end of the push rod 9, and the inclined surface of the triangular block 11 is set as a smooth surface to reduce the friction between the push rod 9 and the inclined surface of the triangular block 11; a plurality of load-bearing plates 18 are fixedly connected between a pair of support frames 1, and the load-bearing plates 18 are made of stainless steel plates.

[0026] In this embodiment, multiple load-bearing plates 18 support a pair of support frames 1, and the clamping block 20 is easily raised and lowered by the triangular block 11 and push rod 9.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
