Description

Technical Field

[0001] The utility model relates to cleaning equipment, in particular to cleaning equipment using dry ice. 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 reaction 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 surface of the dirt, 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, generating a strong peeling force, quickly and thoroughly removing the dirt from the surface of the object, thereby achieving a fast, efficient, safe and energy-saving cleaning effect. The carbon dioxide used in dry ice cleaning comes from industrial waste gas, high-altitude air separation, etc. Dry ice cleaning itself does not produce carbon dioxide.

[0003] Traditional dry ice cleaning machines are generally used in commercial and industrial fields, so they need to be used with large screw air compressors. They are large in size and inconvenient to use. Research on household dry ice cleaning machines has always been blank. Utility Model Content

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships described in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "installed / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0026] refer to Figure 1-Figure 5 The present embodiment provides a shoulder-type dry ice cleaning machine, comprising: a dry ice cleaning machine body 1, a spray gun and a shoulder strap 2; the shoulder strap 2 is connected to the back of the dry ice cleaning machine body 1. By providing the shoulder strap 2, the user can carry the dry ice cleaning machine body 1 for use. Of course, in order to allow the user to carry the dry ice cleaning machine body 1, the dry ice cleaning machine body 1 needs to be reduced in weight. The present application mainly reduces the weight of the rotary cutting disc and the transmission mechanism. In addition to the double-shoulder shoulder strap shown in the present embodiment, the shoulder strap 2 can also be changed to a single-shoulder shoulder strap or other common shoulder straps.

[0027] In addition, since the dry ice cleaning machine is designed to be miniaturized and lightweight, the corresponding air path diameter is reduced, so the air compressor adapted thereto can also be miniaturized. For this reason, the present embodiment also includes a portable air compressor, whose air outlet end is used to connect to the air inlet end of the dry ice cleaning machine body 1, and the air outlet end of the dry ice cleaning machine body 1 is used to connect to the spray gun.

[0028] In order to reduce the weight of the transmission mechanism and the rotary cutting disc, the dry ice cleaning machine body 1 in this embodiment includes a lightweight rotary cutting device for block dry ice;

[0029] The lightweight peeling device further comprises a transmission device 11, a peeling plate 12 and a container 13; the transmission device 11 is used to drive the peeling plate 12 to rotate;

[0030] The container 13 is used to place dry ice, and a clamping device 14 is provided on the first side of the container 13; the clamping device 14 is used to push the dry ice to the second side, and the peeling plate 12 is provided on the second side, and a blade is fixed on the peeling plate 12, and the blade is inclined from the second side to the first side, and a gap is left between the blade and the peeling plate 12; in this embodiment, the clamping device 14 adopts a push plate driven by a cylinder.

[0031] The side of the peeling plate 12 away from the container 13 is connected to the fixed plate 16 through a connecting column 15; the axis of the fixed plate 16 is provided with a mounting hole for fixing the peeling plate shaft 17; the fixed plate 16 is provided with a through groove along the thickness direction for weight reduction.

[0032] The transmission device 11 is mainly used to drive the peeling plate 12 to rotate. The peeling plate 12 abuts against the dry ice in the container 13 during the rotation process. The blades on the peeling plate 12 can cut the dry ice into pieces. The cut dry ice is blown out by the air blown in by the air compressor to form an airflow with dry ice particles, which is sprayed from the spray gun to achieve the purpose of cleaning. The transmission device 11 includes: a brushless motor 111 and a gear transmission mechanism 112; the gear transmission mechanism 112 includes a first gear arranged on the output shaft of the brushless motor 111, a second gear arranged on the peeling plate rotating shaft 17 of the peeling device, and an intermediate gear connected between the first gear and the second gear. As a simple replacement for this embodiment, the intermediate gear can also be removed, and the first gear and the second gear can be directly meshed.

[0033] By changing the metal chain drive to gear drive, the weight of the transmission mechanism can be greatly reduced. Furthermore, the material of the first gear, the second gear and the intermediate gear can be changed from metal to nylon to achieve the purpose of further weight reduction.

[0034] Furthermore, since the second gear disposed on the peeling plate 12 is relatively large in size, a through groove may be provided in the second gear along the thickness direction to further reduce weight.

[0035] To fix the second gear and the peeling plate shaft 17, the peeling plate shaft 17 is installed on the side of the second gear facing the peeling plate 12 through a fixing pin. Further, the peeling plate shaft 17 includes a shaft body 171 and a mounting plate 172, and the mounting plate 172 is provided with a socket connected to the fixing pin; the mounting plate is provided with a through groove along the circumferential direction for weight reduction.

[0036] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
