Description

Technical Field

[0001] This utility model belongs to the technical field of packaging bag unpacking devices, specifically relating to a packaging bag unpacking and clumping crushing mechanism and crushing and transfer device. Background Technology

[0002] Many production lines require three to five main raw materials (such as potassium chloride, ammonium sulfate, etc.) depending on the production formula. The raw materials are usually packaged in 50 kg / bag or 25 kg / bag. The packaging bags are made of nylon woven bags. After the raw materials are transported to the factory, the material bags are poured into the feeding port for material mixing.

[0003] In existing technology, the bag is cut open manually with a knife before the material is poured into the feeding port. However, some materials may clump together inside the bag. In this case, it is necessary to observe whether clumps are present before and after cutting the bag. If clumps are found, they need to be manually broken into smaller pieces. This method of manually breaking up clumps is time-consuming and labor-intensive, reduces production efficiency, generates a lot of dust, and poses a significant health hazard and safety risk to workers due to contact with the materials. Therefore, it has poor practicality. Utility Model Content

[0041] Please refer to the following: Figures 1 to 3This invention provides a packaging bag unpacking and clumping crushing mechanism and crushing transfer device. The packaging bag unpacking and clumping crushing mechanism includes a connecting frame 10, positioning structures 20, and an auxiliary crushing component 30. Two positioning structures 20 are provided, spaced apart. Each positioning structure 20 is connected to the connecting frame 10. Each positioning structure 20 has multiple vertically downward extending positioning insertion parts. The positioning structures 20 are used to position the material bag by inserting the positioning insertion parts into the material bag to be unpacked. The auxiliary crushing component 30 is disposed on the connecting frame 10. The auxiliary crushing component 30 has a crushing part located between the two positioning structures 20. The auxiliary crushing component 30 is used to drive the crushing part to reciprocate vertically to crush the material inside the material bag fixed by the two positioning structures 20.

[0042] In this embodiment, two positioning structures 20 are provided, spaced apart on the connecting frame 10. Each positioning structure 20 has multiple positioning insertion parts, each of which extends vertically downward. The positioning insertion parts are inserted into the material bag to be unpacked, and the material bag is positioned by these parts. An auxiliary crushing assembly 30 is also provided on the connecting frame 10. The auxiliary crushing assembly 30 has a crushing part located between the two positioning structures 20. The auxiliary crushing assembly 30 drives the crushing part to reciprocate up and down, thereby crushing the material inside the material bag, which is fixed by the two positioning structures 20.

[0043] This utility model provides a packaging bag unpacking and clumping crushing mechanism. Compared with the prior art, it features a connecting frame 10 with two positioning structures 20 spaced apart on the frame 10. Each positioning structure 20 has multiple positioning insertion parts that extend vertically downwards. These parts are inserted into the material bag to be unpacked, thus positioning the bag. An auxiliary crushing component 30 is also provided on the connecting frame 10. This component has a crushing part located between the two positioning structures 20. The auxiliary crushing component 30 drives the crushing part to reciprocate, thereby crushing the material inside the bag fixed by the two positioning structures 20. In this application, the material bag to be unpacked is first positioned by the two positioning structures 20, and then the material inside is crushed by the reciprocating movement of the crushing part. The bag position remains unchanged, ensuring effective crushing of clumps inside the bag. This method is time-saving, labor-saving, reduces labor intensity, improves work efficiency, and is highly practical.

[0044] In some embodiments, please refer to Figures 1 to 3Each positioning structure 20 includes a crossbar 21 and a connecting post 22. The crossbar 21 is horizontally mounted on the connecting frame 10. The length direction of the crossbar 21 is defined as the first direction. There are multiple connecting posts 22, which are spaced apart on the crossbar 21 along the first direction. Each connecting post 22 is a positioning insertion part. In this embodiment, the crossbar 21 is horizontally mounted on the connecting frame 10, and multiple connecting posts 22 are provided on the crossbar 21. The connecting posts 22 are spaced apart and are used to insert into the material bag to be unpacked to limit the position of the material bag, thereby ensuring that the position of the material bag does not shift.

[0045] In some embodiments, please refer to Figures 1 to 3 The crossbar 21 is rotatably connected to the connecting frame 10. Each positioning structure 20 also includes a first driving cylinder 23, one end of which is rotatably connected to the adapter connecting frame 10, and the other end is rotatably connected to the adapter rod 24 provided on the crossbar 21. Specifically, the adapter rod 24 has a first adapter end and a second adapter end. The first adapter end is hinged to the other end of the first driving cylinder 23, and the second adapter end is connected to the crossbar 21. In this embodiment, the end of the first driving cylinder 23 connected to the adapter rod 24 is a telescopic end. The telescopic end of the first driving cylinder 23 is rotatably connected to the first adapter end of the adapter rod 24, and the second adapter end of the adapter rod 24 is connected to the crossbar 21, thereby driving the adapter rod 24 to rotate through the first driving cylinder 23, and the adapter rod 24 drives the crossbar 21 to rotate. After the auxiliary crushing component 30 has finished crushing the agglomerated material, the first drive cylinder 23 is activated, driving the crossbar 21 to rotate. The insertion pins 22 on the two crossbars 21 rotate towards each other (i.e., the insertion pins 22 rotate towards the two crossbars 21, and the insertion pins 22 on the two crossbars 21 rotate from the vertical direction to the horizontal direction or tilt at a certain angle), ensuring the stability of the insertion pins 22 into the material bag. When it is necessary to position the material bag, the first drive cylinder 23 drives the crossbar 21 to rotate, and the insertion pins 22 on the two crossbars 21 rotate in opposite directions (i.e., the insertion pins 22 rotate downwards) until the insertion pins 22 are in a vertical state.

[0046] In some embodiments, please refer to Figure 1 and Figure 2 The auxiliary crushing component 30 includes a base plate 31 and a telescopic structure. The base plate 31 is horizontally positioned, and multiple protrusions 32 are evenly distributed on its lower surface, each protrusion 32 serving as a crushing part. The telescopic structure is mounted on the connecting frame 10 and has a telescopic end connected to the base plate 31, used to drive the base plate 31 to reciprocate up and down. In this embodiment, the base plate 31 is horizontally positioned, and multiple protrusions 32 are provided on the base plate 31. Simultaneously, the telescopic end of the telescopic structure is connected to the base plate 31, thereby driving the base plate 31 to reciprocate up and down through the telescopic structure, thus crushing clumps in the material bag through the protrusions 32 on the base plate 31, making operation convenient.

[0047] In some embodiments, please refer to Figure 1 and Figure 2 Each protruding structure 32 includes a first inclined plate 321 and a second inclined plate 322. The first inclined plate 321 is inclined and has a first upper end and a first lower end, with the first upper end connected to the base plate 31. The second inclined plate 322 is also inclined and has a second upper end and a second lower end. The second upper end is connected to the base plate 31, and the second lower end is connected to the first lower end. The second inclined plate 322, the first inclined plate 321, and the base plate 31 together form a triangular cross-section. In this embodiment, the first inclined plate 321 and the second inclined plate 322 are both inclined, with the first upper end and the second upper end connected to the base plate 31, and the second lower end connected to the first lower end, thus forming a triangular cross-section. The triangular protruding structures 32 break up the clumps, ensuring effective clumping and improving work efficiency.

[0048] In some embodiments, please refer to Figure 1 and Figure 2 The connecting frame 10 includes a base plate 11, a connecting plate 12, and a vibrating cylinder 13. The connecting plate 12 is located below the base plate 11, and one end of the connecting plate 12 is connected to the base plate 11. The connecting plate 12 is used for mounting the positioning structure 20. The vibrating cylinder 13 is located between the base plate 11 and the connecting plate 12, and the piston rod of the vibrating cylinder 13 is connected to the connecting plate 12. In this embodiment, the vibrating cylinder 13 generates a vibrating effect by rapidly and alternately introducing and discharging compressed air, causing the piston rod to generate a high-frequency short-stroke reciprocating motion (typically a few millimeters) on the piston rod. Preferably, a universal floating joint is provided between the vibrating cylinder 13 and the connecting plate 12, so that the vibrating cylinder 13 causes the connecting plate 12 to generate a vibrating effect.

[0049] In some embodiments, please refer to Figure 1 and Figure 2 The telescopic structure includes a second drive cylinder 33 and a guide rod 34. One end of the second drive cylinder 33 is connected to the base plate 11, and the other end is connected to the bottom plate 31. The guide rod 34 is arranged vertically, with its bottom end connected to the bottom plate 31, its slidable connection to the connecting plate 12, and its top end extending out of the connecting plate 12. In this embodiment, the end of the second drive cylinder 33 connected to the bottom plate 31 is the telescopic end. The bottom end of the guide rod 34 is connected to the bottom plate 31, and the guide rod 34 is slidably connected to the connecting plate 12, thereby driving the bottom plate 31 to reciprocate up and down through the second drive cylinder 33.

[0050] In some embodiments, please refer to Figures 1 to 3The connecting plate 12 includes a plate body 121 and mounting bases 122. The plate body 121 is located below the substrate 11. Multiple mounting bases 122 are provided, each positioned on the side of the plate body 121 away from the substrate 11. Each mounting base 122 is used for rotatably connecting two crossbars 21. In this embodiment, multiple mounting bases 122 are provided on the plate body 121, each used for rotatably connecting two crossbars 21, thereby driving the adapter rod 24 to rotate via the first drive cylinder 23, which in turn drives the crossbars 21 to rotate.

[0051] Based on the same inventive concept, this application also provides a crushing and transfer device, including a packaging bag unpacking and clumping crushing mechanism as described in the above embodiments. Because the crushing and transfer device provided by this utility model includes a packaging bag unpacking and clumping crushing mechanism as described in the above embodiments, it possesses all the beneficial effects of the aforementioned packaging bag unpacking and clumping crushing mechanism. The crushing and transfer device includes a robotic arm connected to a connecting frame 10. Specifically, the robotic arm drives the connecting frame 10 to move to the material bag to be unpacked, facilitating the insertion of the positioning structure 20 into the material bag for positioning. After the auxiliary crushing component 30 has crushed the material inside the material bag, the robotic arm drives the connecting frame 10 to the bag-cutting station to cut open the material bag on the connecting frame 10 and pour out the material. During the pouring process, the shaking cylinder 13 is activated, causing the connecting plate 12 to produce a high-frequency shaking effect, completing the unloading of the packaging bag without any residue. After unloading is completed, the shaking cylinder 13 can also cause the packaging bag on the positioning structure 20 to fall off, so that the positioning structure 20 can reposition the new material bag to be unpacked.
