[0025] The utility model provides a kind of cylinder cleaning, such as Figure 1 And Figure 2 As shown in the figure, the cylinder cleaning is in the shape of a circular tube, and sequentially arranged along its axial direction are a cleaning section 1, a reduced-diameter section 2 and a cleaning section 1, the diameter of the reduced-diameter section 2 is smaller than that of the cleaning section 1, each cleaning section 1 is provided with an open slot 3 extending from the end of the cylinder cleaning to the axial middle part, the open slot 3 penetrates the side wall of the cylinder cleaning, each cleaning section 1 is provided with multiple open slots 3, and the multiple open slots 3 are circumferentially distributed, the open slots 3 on one of the cleaning sections 1 are arranged staggered with the open slots 3 on the other cleaning section 1.
[0026] Based on the above structure, the multiple open slots 3 provided by the cylinder cleaning allow the cleaning section 1 to be compressed to achieve a reduced diameter, and after the open slot 3 after the diameter reduction is placed in the inner wall of the cartridge, the cleaning section 1 can be better fitted to the inner wall of the cartridge when it rebounds, so as to ensure the cleaning effect; in addition, the two cleaning sections 1 provided can clean the inner wall of the cartridge twice, and the cleaning effect is better, the staggered arrangement of the open slots 3 can allow the place that has not been cleaned due to the arrangement of the open slot 3 when the previous cleaning section 1 is cleaned to be cleaned by the next cleaning section 1, avoiding the occurrence of a place that is not cleaned; and when the previous cleaning section 1 is severely worn, the cylinder cleaning can still be used normally after being turned over, reducing the use cost.
[0027] In the embodiments, each cleaning section 1 is provided with 4 open slots 3, and the open slots 3 on one of the cleaning sections 1 are arranged staggered by 45° with the open slots 3 on the other cleaning section 1. The number of open slots 3 can meet the functional requirements of deformation and rebound, and can also ensure the strength of the cylinder cleaning. Preferably, the open slot 3 extends to the axial middle of the cylinder cleaning. Preferably, the end of the open slot 3 extending to the axial middle part is provided with a through hole 31, and the diameter of the through hole 31 is greater than the width of the open slot 3. The length of the open slot 3 and the arrangement of the through hole 31 can both make the deformation amount of the cylinder cleaning meet the requirements.
[0028] In the embodiment, the outer side surface of the cleaning section 1 is a first circular ring outer side surface 11, which is used to tightly contact the inner wall of the material cylinder and remove the residues on the inner wall of the material cylinder as the cleaning sleeve moves; the provision of the front and rear first circular ring outer side surfaces 11 can clean the inner wall of the material cylinder twice in one stroke, and the cleaning effect is better; since the wear degree of the front first circular ring outer side surface 11 is generally greater than that of the rear first circular ring outer side surface 11, the cleaning sleeve can still be used after the cleaning sleeve is turned over when one of the first circular ring outer side surfaces 11 is seriously worn. The provision of the reduced diameter section 2 can make the length of the cleaning sleeve long enough to make the deformation of the cleaning section 1 larger, and the reduced diameter section 2 can be prevented from contacting the inner wall of the material cylinder after the provision of the reduced diameter section 2, so as to reduce the friction between the cleaning sleeve and the inner wall of the material cylinder.
