Description

Technical Field

[0001] The present application relates to the technical field of 3D printing equipment, and in particular to a magnetic cleaning machine. Background Art

[0002] During the production of 3D-printed products, a significant amount of printing consumables remains on the surface of the finished product immediately after printing. This residue needs to be cleaned to prevent it from drying and affecting the surface precision of the printed product. Currently, many manufacturers, to improve production efficiency, use cleaning machines to simultaneously clean multiple printed products. These machines contain a cleaning agent in a washing bucket equipped with a paddle wheel to agitate the agent. A motor is mounted on the outside of the washing bucket to drive the paddle wheel. Multiple printed products are immersed in the cleaning agent, which agitates the paddle wheel to clean the consumables from the printed products. The motor and paddle wheel are connected by a drive shaft, which runs through the bottom of the washing bucket. This connection creates a risk of cleaning agent leakage, and alcohol is often used as the cleaning agent. When the drive shaft collides with other components during rotation, static electricity is generated, and sparks can ignite the alcohol, posing a serious safety hazard. Summary of the Invention

DETAILED DESCRIPTION

[0026] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0027] An embodiment of the present application provides a magnetic cleaning machine for cleaning printed products. Since the cleaning agent uses ethanol, which is flammable and explosive, the magnetic cleaning machine avoids ethanol leakage and ignition.

[0028] like Figure 1-4As shown, the magnetic cleaning machine 100 includes: a frame 10, a cleaning bucket 20 mounted on the frame 10, a magnetic mechanism 30, and a drive motor 40 in transmission connection with the magnetic mechanism 30. The frame 10 supports the cleaning bucket 20 on the ground. The cleaning bucket 20 includes a horizontally extending bottom wall 1 and a barrel wall 2 surrounding the upper surface of the bottom wall 1. The upper surface of the bottom wall 1 and the inner wall surface of the barrel wall 2 define a cleaning chamber 3 capable of accommodating a plurality of printed products and containing cleaning agent. In the embodiment of the present application, the bottom wall 1 of the cleaning bucket 20 is circular, and the barrel wall 2 surrounds the periphery of the bottom wall 1 to form a cylindrical body with a circular cross-section. The middle of the cleaning chamber 3 has a center line X1 extending in the vertical direction.

[0029] like Figure 4-6 As shown, the magnetic mechanism 30 includes a impeller disk 4 suspended above the bottom wall 1 and a rotating disk 5 arranged below the bottom wall 1. The impeller disk 4 and the rotating disk 5 are arranged relatively to each other up and down, and both have the center line X1 as the axis line. When the rotating disk 5 rotates around the center line X1, the impeller disk 4 suspended above the bottom wall 1 rotates synchronously with the rotating disk 5 around the center line X1.

[0030] The drive motor 40 is mounted on the frame 10 and positioned below the magnetic mechanism 30. It is in driving connection with the rotating disk 5 to drive the rotating disk 5 to rotate about the centerline X1. As the rotating disk 5 rotates about the centerline X1 driven by the drive motor 40, the impeller disk 4 rotates about the centerline X1 within the cleaning chamber 3 without contact with the rotating disk 5 or the cleaning bucket 20. The bottom of the cleaning bucket 20 does not have a through-hole connecting the impeller disk 4 and the rotating disk 5, effectively preventing the detergent contained within the cleaning chamber 3 from leaking through the through-hole and posing a safety hazard.

[0031] A protrusion 6 is provided in the cleaning chamber 3, and the protrusion 6 is located between the bottom wall 1 and the impeller disc 4 to suspend and support the impeller disc 4 above the bottom wall 1, so as to avoid large-area direct friction between the impeller disc 4 and the bottom wall 1 of the cleaning bucket 20 during rotation; the protrusion 6 has a cross-section parallel to the bottom wall 1, and the cross-section of the protrusion 6 gradually increases from top to bottom. The top of the protrusion 6 abuts against the bottom surface of the middle part of the impeller disc 4, thereby reducing the contact between the impeller disc 4 and the cleaning bucket 20. In the embodiment of the present application, the protrusion 6 is made of polytetrafluoroethylene, so that the contact between the protrusion 6 and the rotating impeller disc 4 will not generate sparks that ignite the cleaning agent.

[0032] In the embodiment of the present application, a plurality of first magnetic members 7 are arranged on the impeller disk 4 and are distributed in sequence in the circumferential direction around the center line X1. A plurality of second magnetic members 8 are arranged on the rotating disk 5 and are distributed in sequence in the circumferential direction around the center line X1. The number of the first magnetic members 7 is consistent with the number of the second magnetic members 8. Each first magnetic member 7 is arranged relative to a second magnetic member 8 in the upper and lower directions and is magnetically attracted to each other. The magnetic attraction between the first magnetic member 7 and the second magnetic member 8 plays a positioning role, ensuring that the impeller disk 4 and the rotating disk 5 are always in relative positions in the upper and lower directions during the rotation process. Due to the magnetic force, the impeller disk 4 will rotate synchronously with the rotating disk 5, realizing the power drive of the impeller disk 4 when the rotating disk 5 is not in contact with the impeller disk 4.

[0033] A plurality of stirring blades 9 are provided on the upper surface of the impeller 4, and the stirring blades 9 are distributed in sequence around the circumference of the center line X1. When the impeller 4 rotates around the center line X1, the stirring blades 9 stir the detergent in the cleaning chamber 3 at the lower part of the cleaning chamber 3, thereby improving the cleaning efficiency of the printed products.

[0034] like Figure 7 As shown, in another embodiment, a plurality of first magnetic members are arranged on the impeller disk and are distributed in sequence in the circumferential direction around the center line X1. A plurality of second magnetic members 71 and a plurality of third magnetic members 72 are arranged on the rotating disk. The plurality of second magnetic members 71 and the plurality of third magnetic members 72 are alternately arranged in the circumferential direction along the center line X1. The total number of second magnetic members 71 and third magnetic members 72 is the same as the number of first magnetic members. Each second magnetic member 71 is arranged relative to a first magnetic member up and down, and they are magnetically attracted to each other. Each third magnetic member 72 is arranged relative to a first magnetic member up and down, and they are magnetically repelled from each other. The magnetic repulsion between the third magnetic member 72 and the first magnetic member causes the impeller disk 4 to float above the bottom wall 1. The magnetic attraction between the second magnetic member 71 and the first magnetic member plays a positioning role, ensuring that the impeller disk 4 and the rotating disk 5 are relative to each other up and down, and ensuring that the impeller disk 4 rotates synchronously with the rotating disk 5.

[0035] The magnetic mechanism of the present application utilizes the characteristics of like-charged magnetic parts repelling each other and opposite-charged magnetic parts attracting each other to drive the impeller disk in the cleaning barrel to rotate around the center line X1 without providing a connecting through-hole at the bottom of the cleaning barrel, thereby preventing the cleaning agent in the cleaning barrel from leaking from the connecting through-hole and reducing the contact between the impeller disk and the cleaning barrel, thereby avoiding the generation of sparks that ignite the cleaning agent.

[0036] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. The scope of protection claimed in the present application is defined by the appended claims, the description and their equivalents.
