Description

Technical Field

[0001] The utility model relates to the technical field of dry ice cleaning machines, in particular to a feeding mechanism for a dry ice cleaning machine. Background Art

[0002] The cleaning system of the existing dry ice cleaning machine uses high-pressure air to spray dry ice particles of the dry ice cleaning machine onto the working surface that needs to be cleaned, and uses the physical reaction of temperature difference to make different substances separate at different shrinkage speeds. Dry ice cleaning can achieve a fast, efficient, safe and energy-saving cleaning effect. However, the feeding mechanism that usually feeds with a rotating shaft rotates in the ice cleaning machine, and the dry ice particles will cause wear to the plastic parts wrapped on the outside of the shaft body, and the plastic parts need to be replaced regularly. Patent documents have now been made to improve this.

[0003] For example, Chinese patent CN217569983U discloses a feeding mechanism for a dry ice cleaning machine, comprising a shell, a rotating shaft, and two clamping mechanisms; the rotating shaft is rotatably inserted into the front and rear end surfaces of the shell, and the two clamping mechanisms are elastically slidably inserted into the shell relatively, and the clamping mechanism comprises a plastic part and a side plate, one side surface of the plastic part has an arc-shaped groove, the arc of the arc-shaped groove is the same as the arc of the outer diameter of the rotating shaft, the arc surfaces of the two arc-shaped grooves are rotatably fitted with the rotating shaft, one end of the rotating shaft is connected to the output shaft on the reduction box through a coupling, the two side plates are relatively arranged on the shell, and the plastic part and the side plates are fixedly connected by an elastic part; the utility model has good sealing performance and a long replacement cycle, which effectively reduces the maintenance and replacement cost, can perform automatic wear compensation, and extend the service life of the plastic parts. The plastic parts can be taken out and replaced by disassembling the side plates, which is convenient and quick.

[0004] Although the above patent has good sealing performance and a long replacement cycle, which effectively reduces the maintenance and replacement costs and can perform automatic wear compensation, when the multiple grooves on the bearing transport the dry ice particles, the grooves on the bearing are easily blocked by large pieces of dry ice particles, causing the dry ice particles to gradually accumulate on the bearing and be unable to continue feeding, affecting the feeding efficiency of the dry ice cleaning machine.
