Description

Technical Field

[0001] This utility model relates to the field of unloading station equipment, and in particular to an adjustable ton bag breaking device. Background Technology

[0002] Among the many stages of industrial production, unloading at the unloading station is a crucial one.

[0003] Traditional unloading methods involve manually breaking open ton bags. This method is not only inefficient, but the flying material powder during unloading can also be inhaled by the personnel, which can have adverse effects on their health. Some methods use bag-breaking devices to break open ton bags. For example, Chinese Patent No. CN219257976U discloses a ton bag breaking knife assembly for a ton bag unloading station. This patent uses blades arranged in a cross shape. When the ton bag is placed on the breaking knife assembly, a cross-shaped opening is formed on the ton bag, allowing the material inside to fall out. Although this patent can replace manual bag breaking, its breaking knife assembly is not adjustable, making it unsuitable for ton bags of different sizes.

[0004] Therefore, it is necessary to design an adjustable ton bag breaking device to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0005] Based on the above problems, the purpose of this utility model is to provide an adjustable ton bag breaking device to solve the problems existing in the prior art.

[0006] The present invention adopts the following technical solution:

[0007] This utility model provides an adjustable ton bag breaking device, including:

[0008] A base is provided with multiple bag-breaking knife assemblies. The tops of the multiple bag-breaking knife assemblies are clustered together and connected to a connecting assembly. A bag-breaking cone is provided on the connecting assembly, and the bag-breaking cone is located above the middle of the multiple bag-breaking knife assemblies.

[0009] The bag-breaking knife assembly includes a detachable knife holder, the bottom of which is movably connected to the base and limited by a limiting member, the top of which is connected to the connecting assembly, and an upwardly extending blade is provided on the side.

[0010] Furthermore, the detachable tool holder includes a tool holder body one, the bottom of which is movably connected to the base and limited by the limiting member. The top of the tool holder body one is detachably connected to a plurality of sequentially connected tool holder bodies three. The top of the tool holder body three furthest from the tool holder body one is detachably connected to a tool holder body two. The top of the tool holder body two is connected to the connecting assembly.

[0011] Furthermore, the connecting assembly includes a vertically arranged tube, on which the bag-breaking cone is disposed; the outer wall of the tube is provided with a plurality of connecting parts corresponding one-to-one with the split-type knife holder, and the top of the split-type knife holder is connected to the tube through the corresponding connecting parts.

[0012] Furthermore, the bag-breaking cone includes a rod and a cone connected to the rod, the rod being inserted into the tube, and the bottom surface of the cone abutting the top surface of the tube.

[0013] Furthermore, the connecting part includes a pair of connecting lugs disposed on the outer wall of the tube body, the top of the split-type tool holder extends between the two connecting lugs, and is connected by a bolt connection pair.

[0014] Furthermore, the side of the detachable blade holder is provided with a mounting groove, the bottom of the blade extends into the mounting groove, and is fixed by a fixing component.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0026] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1-7 As shown, this embodiment discloses an adjustable ton bag breaking device, including a base 1, on which multiple bag breaking knife assemblies 2 are provided. The tops of the multiple bag breaking knife assemblies 2 are clustered together and connected to a connecting assembly 3. A bag breaking cone 4 is provided on the connecting assembly 3, and the bag breaking cone 4 is located above the middle of the multiple bag breaking knife assemblies 2. The bag breaking knife assembly 2 includes a split-type knife holder 21. The bottom of the split-type knife holder 21 is movably connected to the base 1 and is limited by a limiting member 22. The top of the split-type knife holder 21 is connected to the connecting assembly 3, and an upwardly extending blade 23 is provided on the side.

[0028] In this embodiment, the base 1 includes a square frame 101, with fixing holes 102 at each of the four corners of the square frame 101. A connecting frame 103 arranged in a cross shape is provided inside the square frame 101, and the four ends of the connecting frame 103 are fixedly connected to the inner corners of the square frame 101 respectively. The number of bag-breaking knife assemblies 2 is set to four, and the four bag-breaking knife assemblies 2 are symmetrically arranged in pairs on the two axes of the connecting frame 103. The bottom of the split-type knife holder 21 is movably connected to the connecting frame 103. The connecting frame 103 is provided with multiple sets of spaced limiting holes 1031. The limiting member 22 is set as a screw, which passes through the bottom of the split-type knife holder 21 and is threadedly connected to the limiting hole 1031.

[0029] During installation, the base 1 is fixed between the unloading station hopper and the ton bag using screws through the fixing holes 102. When the ton bag is placed on the present invention, the bag-breaking cone 4 first contacts the ton bag and forms an opening on the ton bag. Then the ton bag contacts the bag-breaking knife assembly 2. The four blades 23 of the bag-breaking knife assembly 2 form a cross opening on the ton bag, thereby allowing the material inside the ton bag to fall.

[0030] With this design, the length of the detachable knife holder 21 can be adjusted. When the length of the detachable knife holder 21 changes, the position of its bottom on the connecting frame 103 also changes. The limiting member 22 facilitates the limiting and fixing or releasing the limiting and fixing of the detachable knife holder 21. Through the above structure, the structural dimensions and angles of the bag-breaking knife assembly 2 of this utility model can be adjusted, so as to better suit ton bags of different sizes.

[0031] To further optimize the design, the side of the split-type tool holder 21 is provided with a mounting groove, the bottom of the blade 23 extends into the mounting groove and is fixed by a fixing component.

[0032] In this embodiment, when the length of the split-type tool holder 21 changes, the length of the corresponding mounting slot also changes. Then, a blade 23 matching the mounting slot is selected and installed. Specifically, the fixing component consists of multiple spaced hexagonal socket screws. Both the blade 23 and the split-type tool holder 21 have screw holes. When the bottom of the blade 23 extends into the mounting slot, it can be fixed using the hexagonal socket screws and screw holes. After the blade 23 is fixed, the cutting edge of the blade 23 extends 2-3 cm beyond the split-type tool holder 21.

[0033] Further optimization of the design: the detachable tool holder 21 includes a tool holder body 1 211. The bottom of the tool holder body 1 211 is movably connected to the base 1 and is limited by the limiting member 22. The top of the tool holder body 1 211 is detachably connected to multiple tool holder bodies 3 212 connected in sequence. The top of the tool holder body 3 212 farthest from the tool holder body 1 211 is detachably connected to the tool holder body 213. The top of the tool holder body 213 is connected to the connecting component 3.

[0034] In this embodiment, the first blade holder 211 and the second blade holder 213 are essential components, while the number of the third blade holder 212 can be increased or decreased according to the size of the ton bag. The first blade holder 211 and the third blade holder 212, the two third blade holders 212, and the third blade holder 212 and the second blade holder 213 are all detachably connected by hexagonal socket screws and screw holes. With the above structure, the length of the split blade holder 21 can be adjusted according to the size of the ton bag; at the same time, the angle between the split blade holder 21 and the horizontal direction will also change, specifically, the angle is set to 55° to 65°.

[0035] Further optimization of the scheme: the connecting component 3 includes a vertically arranged tube 31, and the bag-breaking cone 4 is set on the tube 31; the outer wall of the tube 31 is provided with multiple connecting parts 32 that correspond one-to-one with the split-type knife holder 21, and the top of the split-type knife holder 21 is connected to the tube 31 through the corresponding connecting parts 32.

[0036] In this embodiment, the bag-breaking cone 4 includes a rod 41 and a cone 42 fixedly connected to the rod 41. The rod 41 is inserted into the tube 31, and the bottom surface of the cone 42 abuts against the top surface of the tube 31. The connecting part 32 includes a pair of connecting lugs 321 fixed to the outer wall of the tube 31. The top of the split-type knife holder 21 extends between the two connecting lugs 321 and is connected by a bolt connection pair 322. Specifically, the top of the knife holder body 213 extends between the two connecting lugs 321, and both the two connecting lugs 321 and the top of the knife holder body 213 are provided with through holes for the bolts of the bolt connection pair 322 to pass through.

[0037] This utility model adopts a steel frame structure to improve its stability and reliability; its structure is simple and low in cost, and it can be flexibly disassembled and assembled, making it easy to promote and apply in actual production.

[0038] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
