Description

Technical Field

[0001] The utility model relates to the field of particle dry ice cleaning, and more specifically to a grinding device of a dry ice cleaning machine. Background Art

[0002] Dry ice cleaning machine is a type of cleaning machine. Dry ice cleaning has been developing rapidly around the world. The cleaning system uses high-pressure air to spray dry ice pellets from the dry ice cleaning machine onto the work surface that needs to be cleaned, and uses the physical reflection of temperature difference to make different substances separate at different shrinkage speeds. When the dry ice pellets at -78 degrees Celsius come into contact with the dirt surface, they will produce a brittle explosion phenomenon, causing the dirt to shrink and loosen. Then the dry ice pellets will instantly vaporize and expand 800 times. The product's strong peeling force will quickly and thoroughly remove the dirt from the surface of the object, thereby achieving a fast, efficient, safe and energy-saving cleaning effect.

[0003] Before using dry ice for cleaning, the dry ice needs to be ground into fine particles. Since the existing grinding device is usually fixed as a set, it is difficult to adjust the grinding device according to the size of the grinding particles, resulting in the size of the fine dry ice particles being uncontrollable. It is difficult for users to adjust the grinding device according to their needs to adjust the size of the dry ice particles, which is inconvenient. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-3As shown, in the first embodiment of the grinding device of the dry ice cleaning machine of the present invention, the grinding device 10 includes an inner blade assembly, an outer blade assembly and a base 11.

[0029] The inner blade assembly includes a rotating shaft 12 rotatably disposed on the base 11 and an inner blade seat 13 mounted on the rotating shaft 12 and rotating with the rotating shaft 12 .

[0030] The outer blade assembly includes an outer blade seat 14 installed on the base 11 .

[0031] The inner blade seat 13 is embedded in the outer blade seat 14 , and the embedding depths of the inner blade seat 13 and the outer blade seat 14 are adjustable.

[0032] It can be understood that the rotating shaft 12 is used to be directly or indirectly connected to the output shaft of the driving motor. After the rotating shaft 12 is directly or indirectly connected to the output shaft of the driving motor, the rotating shaft 12 is in a fixed state. At the same time, the inner tool holder 13 installed on the rotating shaft 12 is also in a fixed state.

[0033] When it is necessary to adjust the distance between the inner blade seat 13 and the outer blade seat 14, the position of the outer blade seat 14 on the base 11 can be adjusted, or the positions of the base 11 and the outer blade seat 14 can be adjusted at the same time, so that the embedded depth of the inner blade seat 13 and the outer blade seat 14 is adjusted, thereby adjusting the dry ice particles formed by grinding to be larger.

[0034] When using the grinding device of the dry ice cleaning machine of the utility model, the rotating shaft 12 is directly or indirectly connected to the output shaft of the driving motor to fix the rotating shaft 12 and the inner blade seat 13. When it is necessary to adjust the distance between the inner blade seat 13 and the outer blade seat 14, the position of the outer blade seat 14 on the base 11 can be adjusted, or the positions of the base 11 and the outer blade seat 14 can be adjusted at the same time, so that the embedded depth of the inner blade seat 13 and the outer blade seat 14 can be adjusted. In this process, since the inner blade seat 13 is not displaced, when the outer blade seat 14 moves, the distance between the outer blade seat 14 and the inner blade seat 13 is adjusted to be larger or smaller. When the outer blade seat 14 moves closer to the inner blade seat 13, the dry ice particles formed by grinding are smaller, and when the outer blade seat 14 moves away from the inner blade seat 13, the dry ice particles formed by grinding are larger. Using the grinding device 10 of the present application, the user can adjust the grinding device 10 according to the grinding coarseness and fineness, and the adjustment difficulty is low, which is convenient for the user to operate.

[0035] In a specific embodiment, the grinding device 10 also includes a threaded member 15 disposed on the top of the outer tool seat 14 and rotatably connected to the outer tool seat 14. The outer tool seat 14 is sleeved outside the inner tool seat 13, and the outer tool seat 14 can move relative to the inner tool seat 13 in a direction away from or close to the inner tool seat 13.

[0036] The threaded member 15 is provided with a first thread 16 , and the outer tool holder 14 is provided with a second thread 17 that can be threadedly connected with the first thread 16 .

[0037] It can be understood that a plurality of inner blade teeth are disposed on the inner side wall of the outer blade seat 14, and a plurality of outer blade teeth are disposed on the outer side wall of the inner blade seat 13, and the plurality of inner blade teeth and the plurality of outer blade teeth are arranged opposite to each other.

[0038] The rotating shaft 12 is used to be directly or indirectly connected to the driving motor. The driving motor drives the rotating shaft 12 to rotate, and the rotating shaft 12 can synchronously drive the inner tool holder 13 installed on the rotating shaft 12 to rotate. Specifically, the inner tool holder 13 can be fixed on the rotating shaft 12, or connected to the rotating shaft 12 by a pin key and rotate with the rotating shaft 12. Further, since the rotating shaft 12 is directly or indirectly connected to the driving motor, when the outer tool holder 14 is adjusted, the inner tool holder 13 will not be displaced.

[0039] In this embodiment, the threaded member 15 is a threaded cover that covers the top of the outer tool holder 14, which will be described in detail later. In other embodiments, the threaded member 15 can also be a threaded column that can be threadedly connected to the outer tool holder 14. When adjusting the outer tool holder 14, the threaded column is fixed and the outer tool holder 14 is rotated to form an adjustment.

[0040] In this embodiment, when adjusting the outer blade seat 14, it is only necessary to fix the threaded member 15, rotate the outer blade seat 14 to drive the second thread 17 to rotate relative to the first thread 16 of the threaded member 15, so that the outer blade seat 14 moves relative to the threaded member 15, thereby achieving the outer blade seat 14 to move closer to or away from the inner blade seat 13. When the outer blade seat 14 moves closer to the inner blade seat 13, the dry ice particles formed by grinding are smaller, and when the outer blade seat 14 moves away from the inner blade seat 13, the dry ice particles formed by grinding are larger.

[0041] When using the grinding device 10 of this embodiment, fix the threaded member 15, and then rotate the outer tool holder 14 so that the outer tool holder 14 rotates relative to the threaded member 15, and the first thread 16 and the second thread 17 cooperate with each other and drive the outer tool holder 14 to move relative to the threaded member 15. In this process, since the inner tool holder 13 does not move, when the outer tool holder 14 moves, the distance between the outer tool holder 14 and the inner tool holder 13 is adjusted to become larger or smaller. When the outer tool holder 14 moves closer to the inner tool holder 13, the dry ice particles formed by grinding are smaller, and when the outer tool holder 14 moves away from the inner tool holder 13, the dry ice particles formed by grinding are larger. Using the grinding device 10 of the present application, the user can adjust the grinding device 10 according to the grinding coarseness and fineness, and the adjustment difficulty is relatively low, which is convenient for the user to operate.

[0054] In order to better disassemble and fix the transverse connecting body 26, the seat body 24 includes a first clamping body 31 and a second clamping body 32. The first clamping body 31 and the second clamping body 32 are detachably fixedly connected.
