After the printing work is finished, the motor of the lifting device is driven to rotate reversely under the control of the driver, so that the cylinder system is driven to move downwards integrally, the cylinder system is separated from the bottom surface of the forming chamber, and when the separation distance reaches a set parameter, the driver gives a signal to stop the motor of the lifting device; then, the motor of the synchronous belt transmission mechanism rotates forwards under the control of the driver, the motor shaft drives the cylinder body to move rightwards on the linear guide rail through the speed reducer, the closed loop belt pulley set, the transmission shaft and the open loop belt pulley set, the position of a proximity switch on the right side of the cylinder system lifting platform is adjusted, the sensing distance of the proximity switch just stops the cylinder body right below the forming chamber, at the moment, the driver gives a signal to stop the synchronous belt transmission mechanism, and starts to drive the motor of the lifting device to make the cylinder body drive the sealing strip to move upwards to be in sealing contact with the powder cleaning chamber, when the size of upwards moving reaches the proximity switch inductive distance of fixing on the cylinder body, the driver makes the motor stall, has realized that the cylinder body carries the product and has moved to under the clear powder room automatically, has reduced manual intervention, has improved the degree of automation of equipment, can improve production efficiency, clear powder room side and top are equipped with the convenient clear powder of window and take out the product simultaneously.

After the powder is cleaned and the product is taken out, the cylinder body automatically returns to the initial position under the control of the driver and the proximity switch to carry out the process again.

The invention has the beneficial effects that:

1) the motor of the lifting device can drive the cylinder system lifting platform to move up and down, so that the cylinder body is driven to move up and down, the contact and separation processes of the upper part of the cylinder body with the forming chamber and the powder cleaning chamber can be automatically completed, and the automation performance of the equipment is improved.

2) The motor driving the synchronous belt transmission mechanism can enable the cylinder body to move left and right on the linear guide rail mechanism; after printing work accomplished elevating gear with cylinder body and shaping room separation, then the driver drive synchronous belt drive mechanism's motor removes the cylinder body and the product of printing the completion under to clear powder room to promote the cylinder body height through elevating gear, with cylinder body and the contact of clear powder room, be convenient for clear powder, avoid artifical transport simultaneously, improved the automated performance of equipment.

3) Proximity switches are arranged on the front side face of the cylinder body and two ends of the cylinder system lifting platform, the extending length of a proximity switch probe can be adjusted to change the stop position of the cylinder body, and the precision of the stop position of the cylinder body in lifting and left-right movement can be improved.

4) The side and the top of the powder cleaning chamber are provided with windows, so that the product can be directly taken out after the powder cleaning is finished, and the process is simple and convenient.

The 3D printing cylinder system moving device, the printer and the method according to the embodiments of the present application are described in detail above. The above description of the embodiments is only for the purpose of helping to understand the method of the present application and its core ideas; meanwhile, for a person skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.

As used in the specification and claims, certain terms are used to refer to particular components. As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. "substantially" means within an acceptable error range, and a person skilled in the art can solve the technical problem within a certain error range to substantially achieve the technical effect. The description which follows is a preferred embodiment of the present application, but is made for the purpose of illustrating the general principles of the application and not for the purpose of limiting the scope of the application. The protection scope of the present application shall be subject to the definitions of the appended claims.

It is also noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a good or system that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such good or system. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a commodity or system that includes the element.

It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

The foregoing description shows and describes several preferred embodiments of the present application, but as aforementioned, it is to be understood that the application is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the application as described herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the application, which is to be protected by the claims appended hereto.
