[0034] In order to facilitate the understanding of the present invention, a plurality of embodiments will be given below to provide a more comprehensive description of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.
[0035] The scraper cleaning device in this article is installed in the 3D printing equipment, and the scraper is located at the lower powder outlet of the powder spreader. The black substance is mainly the binder sprayed by the print head during the printing process. Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by technicians in the technical field of the utility model. The terms used in this article in the specification of the utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this article includes any and all combinations of one or more related listed items.
[0036] In one embodiment, the present application provides a scraper cleaning device, which is installed in a 3D printing device, and includes a cleaning component, a rotating component and a moving component. The moving component is drivingly connected to the rotating component, and the cleaning component is connected to the rotating component; the moving component drives the rotating component to move, and the rotating component drives the cleaning component to rotate and clean the scraper.
[0037] The moving component drives the rotating component to move, and the rotating component drives the cleaning component to rotate. During the cleaning process, the cleaning component can clean the scraper while moving and rotating, which not only has high cleaning quality but also high cleaning efficiency.
[0038] The viscous material conveying system is described below in conjunction with a specific embodiment to further understand the concept of the scraper cleaning device. Figure 1 and attached Figure 3 A scraper cleaning device is installed in a 3D printing device, comprising a cleaning component 100, a rotating component 200 and a moving component 300. The moving component is installed on the frame of the 3D printing device, and the rotating component is fixedly connected to the moving end of the moving component, so that when the moving component moves, the rotating component can be driven to move. The cleaning component is drivingly connected to the rotating component, and when the rotating component rotates, the cleaning component can be driven to rotate. When the cleaning component performs cleaning work, it can achieve cleaning while moving and rotating under the drive of the moving component and the rotating component.
[0039] In one embodiment, referring to the attached Figure 3 As shown, the moving component 300 adopts a screw slider mechanism 310. Specifically, the screw is connected to the frame of the 3D printing device, and a connecting plate 320 is fixedly arranged on the slider, and the connecting plate can be set to an L shape. One side of the connecting plate is fixedly connected to the slider. When the screw is rotated, the connecting plate moves linearly. The rotating component 200 is installed on the other side of the connecting plate 320. Furthermore, the rotating component 200 adopts a motor. The motor is fixed on the connecting plate and the output shaft is fixedly connected to the cleaning component. The rotation of the motor drives the cleaning component to rotate, and then cleans the scraper. It should be noted that the moving component mainly realizes the movement of other components (linear operation), and can also adopt belt conveyors, chain conveyors, linear motors and other structures, as long as linear operation can be achieved. The rotating component mainly drives the cleaning component to rotate, and can achieve rotary motion.
[0040] In one embodiment, referring to the attached Figure 2As shown, the moving assembly 300 includes a horizontal moving mechanism and a vertical lifting mechanism. The horizontal moving mechanism adopts the screw slider structure 310 in the above embodiment, and the vertical lifting mechanism adopts the cylinder 330. Specifically, the cylinder base is fixed on the slider, the output end is connected to one side of the connecting plate, and the other side of the connecting plate is connected to the rotating assembly (motor). When the cylinder is extended and retracted, it can drive the rotating assembly to rise and fall, and the rotating assembly moves up and down to adjust the distance between the cleaning assembly and the scraper, so as to more accurately control the coordination between the cleaning assembly and the scraper, so as to improve the cleaning quality and cleaning effect.
[0041] In one embodiment, referring to the attached Figure 1 As shown, the scraper cleaning device also includes a wetting component 500 located on one side of the cleaning component 100. Specifically, the rotating component includes a motor and a mounting plate, and the mounting plate is connected to the moving component. The motor and the wetting component are both fixedly connected to the mounting plate, and the cleaning component is rotationally connected to the motor output shaft, so that the relative positions of the wetting component and the cleaning component remain unchanged. When the moving component is working, the wetting component and the cleaning component can move at the same time. In order to effectively and quickly clean the black matter adhering to the scraper, the setting position of the wetting component is always located in front of the cleaning component. That is, during the cleaning process, the wetting component first wets the scraper, and then the cleaning component cleans it, which can further improve the quality and efficiency of cleaning.
[0042] It should be noted that in this embodiment, the connecting plate 320 in the above embodiment can be used, and the motor and the wetting component are fixedly connected to one side of the connecting plate. It is also possible to use a mounting plate and a connecting plate at the same time, the mounting plate is connected to the connecting plate, and the motor and the wetting component are fixedly connected to the mounting plate. Further, the mounting plate and the connecting plate can be movably connected, such as providing a strip hole, and the mounting plate can be adjusted up and down relative to the connecting plate through threaded engagement, so that the distance between the cleaning component and the scraper can also be adjusted.
[0043] In one embodiment, the wetting component includes a spraying mechanism or a humidifying mechanism for wetting the scraper surface. For example, the spraying mechanism can spray foam, spray, water or solvent onto the scraper. The humidifying mechanism can be a humidifying sponge or wet cotton cloth or a rubber strip with water, etc., as long as it can wet the scraper.
[0044] In one embodiment, referring to the attached Figure 3 As shown, two groups of wetting components 500 can be provided, respectively located on both sides of the cleaning component 100. Preferably, the two groups of wetting components can be symmetrically arranged on both sides of the cleaning component. When the rotating component rotates forward and reversely, bidirectional cleaning can be achieved, and the cleaning efficiency is higher.
[0045] In one embodiment, referring to the attached Figure 1 and 2As shown, the scraper cleaning device also includes a shielding component 600, which is close to the side of the cleaning component and away from the wetting component. Furthermore, one end of the shielding component abuts against the scraper, and the other end is connected to the rotating component. It should be noted that the rotating output end of the rotating component is driven by the cleaning component, and the shielding component is fixedly connected to the mounting seat of the rotating component, such as the mounting plate in the above embodiment. In this way, the shielding component, the cleaning component and the wetting component can all move synchronously with the moving component. When the cleaning component rotates at high speed for cleaning, sand, flying liquid, etc. will be thrown out, and the shielding component is arranged on one side of the cleaning component for shielding.
[0046] In one embodiment, in order to quickly wet and soften the black substance on the scraper, the liquid used or sprayed by the wetting component may be water or an organic solvent.
[0047] In one embodiment, the scraper cleaning device comprises a cleaning component, a rotating component, a moving component and a shielding component located on one side of the cleaning component. One end of the shielding component abuts against the scraper, and the other end is connected to the rotating component.
[0048] When cleaning components
[0049] In one embodiment, in order to ensure the dustproof effect, a flexible member, such as a brush or a rubber plate, is provided at one end of the shielding assembly close to the scraper, which is in flexible contact with the scraper, not only having a good shielding effect but also not affecting the surface quality of the scraper.
[0050] In one embodiment, the cleaning assembly may include one or more rotating wheels, and a detachable flexible cleaning member is arranged along the circumference of the rotating wheel. The flexible member contacts the scraper and rotates at high speed to remove black matter on the scraper surface. The cleaning member may be linen, cotton cloth, sponge, brush, felt, rubber, etc. In order to improve the cleaning quality and effect, different cleaning members may be installed on each rotating wheel. The cleaning member is detachable, which not only allows the worn cleaning member to be replaced in time, but also allows the cleaning member of different materials or sizes to be replaced for different scrapers or printing environments, so as to have a wider range of adaptability.
[0051] When cleaning the scraper, the sander moves to the cleaning position, and the scraper cleaning device starts working. At this time, the wetting component first wets the scraper, and then the cleaning component performs high-speed rotation cleaning. It should be noted that the cleaning process can be bidirectional cleaning, or multiple reciprocating cleaning can be performed according to the cleaning effect.
[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
