[0004] In the above technical solution, when there are a lot of impurities in the filter box, the filter holes will be blocked, resulting in the filter box needing to be cleaned frequently to ensure the filtering effect. The operation is complicated and seriously affects the filtering efficiency. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0023] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The “first” and “second” involved in the present utility model do not represent specific quantities and orders, but are merely used to distinguish names.

[0026] Combined with Figure 1 and 2 , a raw material filtering device for producing photocurable coatings in this embodiment comprises a tank body 1 and a movable cover 2, the movable cover 2 is threadedly connected to the upper open end of the tank body 1, a motor 3 is arranged on the movable cover 2, and the output shaft of the motor 3 is arranged vertically downward, a rotating shaft 4 and a filter box 5 are arranged in the tank body 1, the rotating shaft 4 is connected to the output shaft of the motor 3, the filter box 5 is installed on the rotating shaft 4, a partition 6 is arranged in the filter box 5, the partition 6 is connected to the rotating shaft 4, the partition 6 is arranged in the middle and lower part of the filter box 5, the partition 6 and the bottom surface of the filter box 5 are spaced apart to form a cavity for accommodating impurities, an annular airbag 7 is arranged between the edge of the partition 6 and the inner wall of the filter box 5, the annular airbag 7 is connected to the partition 6, and an inflatable member 8 connected to the annular airbag 7 is arranged on the lower end surface of the partition 6, when the annular airbag 7 is evacuated to vacuum, a channel allowing impurities to pass is formed between the edge of the partition 6 and the inner wall of the filter box 5.

[0027] The raw material filtering device for the production of photocurable coatings stops rotating after the raw materials in the filter box 5 are filtered each time, and the annular airbag 7 is evacuated to a vacuum state. At this time, the impurities attached to the inner wall of the filter box 5 fall downward to the bottom of the partition 6 due to the centrifugal force. When new raw materials are added, the annular airbag 7 is first inflated to prevent the new raw materials from mixing with the separated impurities. In this way, the cleaning frequency of the filter box 5 can be effectively reduced, and the filtering efficiency of the raw materials can be improved.

[0028] As a preferred solution of the utility model, the upper end surface of the partition 6 is a slope structure with a high middle and a low edge, similar to an inverted cone structure, to prevent excessive impurities from remaining on the partition 6.

[0029] As a preferred solution of the utility model, a counterweight block 9 is provided on the lower end face of the partition 6, which is symmetrically arranged with the inflatable member 8 with the rotating shaft 4 as the center. The weight of the counterweight block 9 is close to the weight of the inflatable member 8, and preferably the same, mainly to reduce the influence of the eccentric force of the partition 6 on the rotating shaft 4 when the partition 6 rotates at high speed.

[0030] As a preferred solution of the utility model, the partition 6 is rotatably connected to the rotating shaft 4 through a bearing. The specific principle is that in the initial stage of rotation of the filter box 5, the annular airbag 7 is in an expanded state. At this time, the filter box 5 drives the partition 6 to rotate through the friction with the annular airbag 7. When the filter box 5 starts to rotate at high speed, the annular airbag 7 is deflated. At this time, the partition 6 loses its force and its rotation speed will slowly decrease, thereby avoiding damage to the inflatable part 8 due to long-term high-speed rotation.

[0031] As a preferred solution of the utility model, in order to increase the falling speed of impurities, a vibration structure 10 for driving the filter box 5 to vibrate is also included. Specifically, the vibration structure 10 includes a movable plate 101 and a cylinder 102. The movable plate 101 is arranged below the filter box 5. The cylinder 102 is installed on the movable cover 2. The cylinder 102 is used to control the movable plate 101 to move up and down in the tank body 1. A vibrator 103 is provided on the upper end surface of the movable plate 101. When the filter box 5 stops rotating, the movable plate 101 moves upward to make the vibrator 103 abut against the lower end surface of the filter box 5 and transmit vibration.

[0032] As a preferred solution of the utility model, in order to improve the uniformity of vibration, the movable plate 101 is an annular structure, and a plurality of vibrators 103 are evenly distributed along the circumferential direction of the movable plate 101. Multiple vibrators 103 simultaneously abut against the lower end surface of the filter box 5 to better transmit vibration and make impurities fall faster.

[0033] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
