Description

Technical Field

[0001] This utility model relates to a dry ice cleaning machine. Background Technology

[0002] A dry ice cleaner is a cleaning device that uses high-pressure gas to blow dry ice particles onto the surface of an object to be cleaned. It typically consists of a feeding assembly, an ice distribution wheel, and a spraying assembly. The ice distribution wheel's function is to transfer the dry ice particles from the feeding assembly to the spraying assembly, where they mix with the high-pressure air before being blown out.

[0003] Therefore, the amount of dry ice particles blown out of the jet assembly depends on the amount of dry ice particles transported by the ice-dispensing wheel. However, after prolonged use, the grooves in the ice-dispensing wheel used to hold dry ice particles can become frosted and icy, causing the grooves to become shallower. This reduces the number of dry ice particles that can be held in the grooves, resulting in fewer dry ice particles being blown out. Consequently, there is a problem of unstable dry ice jet output. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide an ice distribution wheel for a dry ice cleaning machine, which can prevent the frost and ice in the groove of the ice distribution wheel from becoming shallow due to long-term operation, thus affecting the stability of the ice spray volume.

[0005] To solve the above-mentioned technical problems, this utility model provides an ice distribution wheel for a dry ice cleaning machine, which is used to transfer dry ice particles from the feeding assembly to the spraying assembly. The ice distribution wheel is provided with a groove for loading dry ice particles, and the inner wall of the groove is provided with an anti-stick coating.

[0006] In a preferred embodiment: the anti-stick coating is a Teflon coating.

[0007] In a preferred embodiment, the inner wall of the groove is an inclined slope.

[0008] In a preferred embodiment, the inner wall of the groove is an inclined arc surface.

[0009] In a preferred embodiment: the ice-dispensing wheel is driven to rotate around its own axis, so that the groove moves back and forth between the receiving position and the discharging position.

[0010] In a preferred embodiment: the ice-feeding wheel is not provided with an anti-stick coating in the area outside the groove.

[0011] This utility model also provides a dry ice cleaning machine, which includes the ice-dispensing wheel as described above.

[0012] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0013] This invention provides an ice-dispensing wheel for a dry ice cleaning machine. By setting an anti-stick coating in the groove of the ice-dispensing wheel, the occurrence of frost and ice formation in the groove can be greatly reduced, thereby keeping the depth of the groove at a stable state. The amount of dry ice particles transported by the ice-dispensing wheel is also relatively stable, and the dry ice particles will not decrease over time.

[0014] This invention provides an ice-filled wheel for a dry ice cleaning machine. The inner wall of the groove of the ice-filled wheel is an inclined slope or arc surface, which allows the dry ice particles in the groove to fall off more easily, thereby effectively reducing the adhesion of dry ice particles. The effect is even better when used with an anti-stick coating.

[0015] This invention provides an ice-dispensing wheel for a dry ice cleaning machine. The ice-dispensing wheel does not have an anti-stick coating on the area outside the groove, which can avoid the adverse effects of the coating falling off or the gasket being accelerated due to friction between the ice-dispensing wheel and the gasket during rotation.

[0019] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0020] refer to Figures 1-3This embodiment provides an ice-dispensing wheel for a dry ice cleaning machine, used to transfer dry ice particles from a feeding assembly to a spraying assembly. The ice-dispensing wheel 1 is provided with a groove 2 for loading dry ice particles, and the inner wall of the groove 2 is provided with an anti-stick coating 3. The ice-dispensing wheel 1 rotates around its own axis under the action of a driving component, so that the groove 2 reciprocates between a receiving position and a dropping position. For example, the ice-dispensing wheel 1 is positioned between the feeding assembly and the spraying assembly. When the groove 2 of the ice-dispensing wheel 1 rotates to align with the bottom of the dropping assembly, the groove 2 is in the receiving position and can hold dry ice particles. When the groove 2 of the ice-dispensing wheel 1 rotates to align with the inlet of the spraying assembly, the groove 2 is in the dropping position, and the dry ice particles in the groove 2 fall into the spraying assembly. Due to the presence of the anti-stick coating 3, the dry ice particles will not adhere to the inner wall of the groove 2 and accumulate during this process. Therefore, even after prolonged use, there is no accumulation of dry ice particles in the groove 2. This ensures that the amount of dry ice particles carried and dropped in the groove 2 is roughly the same each time, guaranteeing that the number of dry ice particles in the jet ejected by the jet assembly is also roughly the same, thus ensuring stability and preventing the dry ice ejection volume from gradually decreasing with increasing usage time.

[0021] In this embodiment, the anti-stick coating 3 is a Teflon coating, but other anti-stick coatings 3 existing in the prior art can also be used as a replacement, which is a simple replacement in this embodiment.

[0022] To further reduce the adhesion of dry ice particles in the groove 2, the inner wall of the groove 2 is an inclined slope or an inclined arc surface. Combined with the anti-stick coating 3, it can achieve a very good anti-adhesion effect for dry ice particles.

[0023] Furthermore, in this embodiment, the ice-dispensing wheel 1 does not have an anti-stick coating 3 in any area outside the groove 2. This is because during rotation, the area outside the groove 2 of the ice-dispensing wheel 1 must be sealed with the gasket to prevent dry ice particles from leaking out. If an anti-stick coating 3 is provided in the area in contact with the gasket, the anti-stick coating 3 will rub against the gasket during rotation, accelerating the aging and wear of the gasket, and there is also a risk of the coating falling off. To ensure that only the groove 2 has the anti-stick coating 3, the entire ice-dispensing wheel 1 can be sprayed with the anti-stick coating 3 first, and then the surface of the ice-dispensing wheel 1 can be machined by removing the surface coating with a lathe tool, leaving only the coating inside the groove 2. Alternatively, the surface of the ice-dispensing wheel 1 can be masked during the coating spraying process, exposing only the groove 2.

[0024] The ice-matching wheel 1 mentioned above can be widely used in various dry ice cleaning machines.

[0025] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
