Description

A household appliance shell processing device

Technical Field

The utility model relates to the technical field of household appliance shells, in particular to a household appliance shell processing device.

Background Art

During the production process of home appliances, the outer shell of the home appliances needs to be painted first, and painting requires the use of a paint spraying device.

Announcement No.: CN209646811U discloses a home appliance paint spraying device with uniform paint spraying, comprising a base plate, the inner wall of the base plate is fixedly connected with a motor, the output end of the motor penetrates the base plate and extends to the outer side of the base plate and is fixedly connected with a turntable. The utility model solves the problem that the existing paint spraying device needs to be operated by personnel and the position of the spray gun needs to be frequently changed, which increases the labor intensity of the operator, and the operator cannot ensure that each surface of the plastic product can be painted consistently. Due to manual errors, the paint spraying on the surface of the home appliance is uneven. The home appliance paint spraying device with uniform paint spraying has the advantage of being able to spray paint evenly, improves the practicality of the paint spraying device, and is convenient for users to use.

The applicant found that there are some deficiencies in use: since the positive and negative threaded columns are directly exposed to the outside, paint will adhere to the positive and negative threaded columns. As the paint accumulates and solidifies, it will affect the sliding of the threaded sleeve, thereby affecting the fixation of the home appliance casing. After painting, it is necessary to wait for the home appliance casing to dry naturally, and the waiting time is long, which affects the price of the next step of the home appliance casing. In addition, during the painting process, excess paint flows directly downward through the casing to the turntable without being collected, resulting in waste.

Therefore, the utility model designs a household appliance shell processing device to solve the problems existing in the prior art.
