Description

Technical Field

[0001] The present application relates to the field of spraying machines, and in particular to a cylinder sleeve for a spraying machine. Background Art

[0002] An airless sprayer is a spraying device that uses a plunger pump to pressurize the paint. The high-pressure paint is transported to the spray gun through a high-pressure hose, and the pressure is released through the nozzle to form atomization, thereby forming a dense coating on the wall surface.

The first cylinder sleeve 210 is arranged inside the outer cylinder 110, and the second cylinder sleeve 220 is threadedly connected to the first cylinder sleeve 210. The heat conducting plate 120 is in contact with the first cylinder sleeve 210 and the second cylinder sleeve 220. The wear-resistant layer 230 is arranged inside the first cylinder sleeve 210 and the second cylinder sleeve 220. A thread groove 211 is arranged inside the first cylinder sleeve 210, and the thread groove 211 can play a connecting role.

[0032] In some specific implementation schemes, a support ring 212 is provided at one end of the first cylinder sleeve 210, and the support ring 212 is in contact with the inside of the outer cylinder 110. The support ring 212 can play a supporting and connecting role. A first sealing gasket 213 is provided on one side of the support ring 212, and the first sealing gasket 213 is in contact with the inside of the outer cylinder 110. The first sealing gasket 213 can improve the sealing performance. A threaded ring 221 is provided at one end of the second cylinder sleeve 220, and the threaded ring 221 is threadedly connected to the thread groove 211. When When the first cylinder liner 210 and the second cylinder liner 220 need to be disassembled, the user can rotate the second cylinder liner 220, and then separate the thread ring 221 from the thread groove 211 to separate the first cylinder liner 210 from the second cylinder liner 220.

The wear-resistant layer 230 is made of high manganese steel to prevent the inner walls of the first cylinder liner 210 and the second cylinder liner 220 from being worn when the piston rod assembly reciprocates.

[0033] The working principle of the cylinder sleeve for the spraying machine is as follows: first, during the operation of the piston rod assembly, the wear-resistant layer 230 is used to prevent the piston rod assembly from wearing the inner walls of the first cylinder sleeve 210 and the second cylinder sleeve 220 when the piston rod assembly reciprocates, thereby improving the strength of the first cylinder sleeve 210 and the second cylinder sleeve 220. At the same time, the heat generated by the first cylinder sleeve 210 and the second cylinder sleeve 220 is conducted through the heat conducting sheet 120, and the outside air contacts the outer cylinder 110 to dissipate the heat of the first cylinder sleeve 210 and the second cylinder sleeve 220. 0 is threadedly connected to the first cylinder liner 210. When the first cylinder liner 210 and the second cylinder liner 220 need to be disassembled, the user can rotate the second cylinder liner 220, and then separate the thread ring 221 from the thread groove 211 to separate the first cylinder liner 210 from the second cylinder liner 220. The disassembly structure can prevent waste of resources. Furthermore, if one of the first cylinder liner 210 and the second cylinder liner 220 is damaged, only the damaged one needs to be replaced, thereby preventing waste of resources and improving practicality.
