Description

Technical Field

[0001] The utility model relates to the technical field of unpacking, in particular to a tool structure of a plastic bottle brick unpacking machine. Background Art

[0002] Bottle bricks are recycled resource products made from waste plastic bottles through recycling, sorting, cleaning, crushing, and extrusion molding. During the production process of bottle bricks, they also need to be disassembled by an unpacking machine. The working principle of the unpacking machine is mainly to disassemble and unload materials through mechanical devices. The materials to be unpacked are put into the unpacking machine, and the materials slide down along the slide plate by gravity. During the sliding process, the rapidly rotating blades cut the materials, and the cut residual bags and materials slide into the material bag separator for screening.

[0003] Therefore, during the use of the unpacking machine, its tool structure directly affects the processing quality of the device. The existing tool structures of unpacking machines often cannot directly disassemble the upper tool holder assembly. Therefore, when the tools on the tool holder are damaged, only the entire installation shaft can be replaced. As a result, when the tools are damaged, the undamaged tools on it also have to be replaced entirely, resulting in increased losses caused by tool damage. Summary of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0023] As Figures 1-4 shown, a tool structure of a plastic bottle brick unpacking machine proposed by the present utility model includes a box body 1, the box body 1 is provided with a through hole up and down, and a plurality of mounting shafts 5 are rotatably arranged side by side therein. A plurality of detachable tool rest assemblies are arranged side by side on the mounting shafts 5, and the plurality of tool rest assemblies on two adjacent mounting shafts 5 are arranged staggeredly.

[0024] In this utility model, when the device needs to be used, the mounting shaft 5 rotates, thereby driving the tool rest assembly thereon to rotate. Two adjacent mounting shafts 5 both drive the tool rest assemblies provided thereon to rotate, so as to perform the unpacking operation on the material located between the two mounting shafts 5. Moreover, after the device has been used for a period of time, the tool rest assembly on the mounting shaft 5 can be disassembled for maintenance, thereby effectively increasing the service life of the tool 10 and prolonging the service life of the device. In addition, when the tool rest assembly is damaged during use, the damaged tool rest assembly can be disassembled and replaced individually, without replacing the entire mounting shaft 5, thus further effectively reducing the losses caused by the damage of the tool rest assembly in the device.

[0025] In an alternative embodiment, it further includes a motor 3, a speed reducer 4 and a transmission shaft 6. The box body 1 is provided with mounting holes that are equal in number to and in one-to-one correspondence with the plurality of mounting shafts 5. The transmission shaft 6 is rotatably arranged in the mounting holes and is coaxially connected to the mounting shaft 5. The output shaft of the motor 3 is coaxially connected to the input shaft of the speed reducer 4, and the output shaft of the speed reducer 4 is coaxially connected to the transmission shaft 6. When using the device, the motor 3 and the speed reducer 4 are installed on the ground or an installation table. The transmission shaft 6 is driven to rotate by the motor 3 and the speed reducer 4. One end of the transmission shaft 6 extends into the box body 1 and can effectively drive the mounting shaft 5 to rotate.

[0026] In an alternative embodiment, the tool rest assembly includes a mounting ring 7 and a tool 10. The mounting ring 7 is fixedly sleeved on the mounting shaft 5. A plurality of tools 10 are detachably arranged on the outer peripheral surface of the mounting ring 7. The plurality of tools 10 are circumferentially evenly distributed around the center of the mounting ring 7. The tool 10 and the mounting ring 7 are detachably arranged. Thus, when disassembling the tool rest assembly, only the tool 10 needs to be disassembled from the mounting ring 7, that is, further, a certain tool 10 on the mounting ring 7 can be disassembled, so that the device can be maintained more accurately.

[0027] In an alternative embodiment, a plurality of first notches are provided on the outer peripheral surface of the mounting ring 7. The length of one end of the first notch away from the outer peripheral surface of the mounting ring 7 is greater than the length of the end of the first notch close to the outer peripheral surface of the mounting ring 7. The cutting tool 10 is slidably disposed in the first notch and is in sliding contact with its inner wall. A plurality of fixing units for fixing the cutting tool 10 are provided on the mounting ring 7. The number of the plurality of fixing units is equal to and corresponds to the number of the plurality of cutting tools 10 one by one. The cutting tool 10 is placed in the first notch, and the inner wall of the first notch is in contact with the outer end of the cutting tool 10, thereby performing preliminary positioning on the cutting tool 10. After the preliminary positioning of the cutting tool 10 is completed, the cutting tool 10 can be fixed by the fixing unit. Moreover, the length of one end of the first notch away from the outer peripheral surface of the mounting ring 7 is greater than the length of the end of the first notch close to the outer peripheral surface of the mounting ring 7. After the cutting tool 10 enters the first notch, it cannot extend out of the first notch in the direction of the first notch. Therefore, before fixing the cutting tool 10, the staff only needs to limit the cutting tool 10 in one direction, effectively reducing the working intensity of the staff in installing the device. And after the cutting tool 10 is fixed, the stability of the cutting tool 10 after installation can be effectively improved.

[0028] In an alternative embodiment, the fixing unit includes a fixing plate 8, a bolt 9 and a nut 11. The fixing plate 8 is installed at one end of the mounting ring 7. The fixing plate 8 is located at the first notch. A plurality of first through holes are provided on the fixing plate 8. Corresponding second through holes are provided on the cutting tool 10. One end of the bolt 9 sequentially passes through the first through hole and the second through hole. The nut 11 is threadedly sleeved on one end of the bolt 9. The nut 11 abuts against the cutting tool 10, and the bolt 9 abuts against the fixing plate 8. When it is necessary to fix the cutting tool 10, the cutting tool 10 is inserted into the first notch and moved to be in contact with the fixing plate 8. The bolt 9 is sequentially passed through the first through hole and the second through hole, and by rotating the nut 11, the nut 11 gradually abuts against the cutting tool 10 during rotation, and the bolt 9 abuts against the fixing plate 8 during the moving process, thereby completing the fixing of the cutting tool 10. And the operation of fixing the cutting tool 10 by the bolt 9 is simple and convenient for disassembly.

[0029] In an alternative embodiment, the cutting end of the cutting tool 10 is symmetrically arranged along its central axis. Since the cutting end of the cutting tool 10 is symmetrically arranged along its central axis, and the cutting tool 10 can effectively perform the unpacking operation when rotating forward, the cutting tool 10 can also extrude the material between the two mounting shafts 5 when rotating in reverse. And during the extrusion process, the unpacking device can also be carried out on the material, so that when the material enters between the two mounting shafts 5 and is blocked, the blocked material can be effectively moved out of between the two mounting shafts 5 in the reverse direction, and it can also effectively prevent the material moving in the reverse direction from being blocked again when entering the two mounting shafts 5.

[0030] It should be understood that the above specific embodiments of the present utility model are only for illustrative explanation or interpretation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model. In addition, the appended claims of the present utility model are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
