Description

Technical Field

[0001] This utility model relates to the field of unpacking equipment technology, specifically an automatic unpacking and feeding mechanism for granular raw material silos. Background Technology

[0002] Granular raw material silos are devices used for storing and processing granular materials. They are widely used in various industries such as chemical, plastics, and food processing. In the process of storing granular raw materials, the packaging bags containing the granules must first be opened and then put into the raw material silo. In order to improve the feeding efficiency of granular raw materials, ton bag unpacking machines are usually installed in the raw material silo to automatically open the packaging bags.

[0003] Currently available unpacking machines typically use robotic arms to grab ton bags containing granules, and then unpack them. While this automatically opens the bags and improves the feeding efficiency of granular raw materials, the unpacking machine can only unpack one bag of granules at a time, making continuous unpacking difficult. Although it does improve feeding efficiency compared to manual unpacking, the time consumed in the process of the robotic arm grabbing the ton bag, waiting for the granules to be released, and releasing the ton bag is relatively long. Therefore, overall, the unpacking efficiency of existing unpacking machines remains low. Utility Model Content

[0035] Embodiment one

[0036] As shown in Figure 3 and Figure 7 , in the embodiment, one side of the hopper 1 is fixedly connected with two symmetrical fixed plates 11, the opposite side of the two fixed plates 11 is rotatably connected with a connecting shaft 53, the two connecting shafts 53 are fixedly connected with a reciprocating screw rod 54, the outer wall of the reciprocating screw rod 54 is threaded with a connecting block 55 fixedly connected with the extension plate 51, one side of one of the fixed plates 11 is fixedly connected with a motor two 56, the output end of the motor two 56 penetrates the fixed plate 11 at the corresponding position and is fixedly connected with the connecting shaft 53 at the corresponding position, the top of the support plate 3 is fixedly connected with a baffle 33 between the two sides of one end close to the saw blade 52, and the two ends of the two sides away from each other of the support plate 3 are fixedly connected with a connecting plate 34 fixedly connected with the hopper 1.

[0037] In the embodiment, the reciprocating screw rod 54 drives the extension plate 51 and the saw blade 52 to reciprocate in the inside of the roller 2 through the driving of the motor two 56, the ton bag is cut off at the waist by the reciprocating saw blade 52 when the ton bag is conveyed to be in contact with the saw blade 52 through the conveying mechanism 4, so that the particles in the ton bag are scattered and fall into the hopper 1, thereby realizing the automatic unpacking function.

[0038] Embodiment two

[0039] As shown in Figure 3 and Figure 8As shown, in this embodiment, retaining rings 21 are fixedly connected to both ends of the roller 2, and multiple fixed rods 22 are fixedly connected at equal angles between the two retaining rings 21. The bottom surface of the support plate 3 is provided with a sliding groove 35, and a sliding rod is fixedly connected between the two ends inside the sliding groove 35. The bag-collecting mechanism 6 includes two symmetrical sliders 61 that slide through the sliding rods at corresponding positions. A moving plate 62 is fixedly connected between the two sliders 61. Multiple insert plates 63 are fixedly connected at equal intervals on the bottom surface of the moving plate 62.
