However, such traditional equipment generally suffers from the following technical defects in practical applications: First, during the mixing process, ink raw materials are prone to adhere to the side wall and bottom of the cylinder due to centrifugal force or their own viscosity, and the existing stirring structure is difficult to effectively clean the raw materials adhering to the wall surface; Second, in order to solve the problem of wall adhesion, some equipment has added a fixed wall scraping component, but this type of component is in a fixed position and will always be in contact with the inner wall of the cylinder during stirring, thereby increasing the wear between the two and affecting the service life of the wall scraping component and the cylinder. Therefore, an ink raw material premixing kettle with a wall scraping structure is proposed to solve the above problems. Utility Model Content

The cross section of the sliding block 405 is in the shape of a Chinese character "shi", the "shi"-shaped structure can prevent the sliding block 405 from slipping out of the inner wall of the guide plate 404, improving sliding safety. The hinged position of the bottom scraper 408 and the side scraper 403 forms a forty-five degree angle, this arrangement avoids motion interference generated during storage.

[0023] Refer to Figure 1 , Figure 2 and Figure 5 , the tilting mechanism 5 includes a rotating shaft 502 fixedly connected to the outer arc surface of the cylinder body 1, the rotating shaft 502 is made of stainless steel, which is rust-proof and rotates smoothly, providing rotational support for the tilting of the cylinder body 1. The outer arc surface of the rotating shaft 502 is rotatably connected with a concave plate 501, the lower outer arc surface of the cylinder body 1 is fixedly connected with an insertion block 504, the inner wall of the concave plate 501 is penetrated and threadedly connected with a limiting screw 505, the insertion block 504 provides a locking carrier for the limiting screw 505, ensuring the stability of the cylinder body 1 when it is stationary.

The front part of the cylinder body 1 is fixedly connected with a handle 503, the handle 503 facilitates the operator to push the cylinder body 1 to tilt, saving time and effort.

[0024] Working principle: Before use, prepare the raw material addition: remove the cover plate 2 connected by the flange, add the ink raw material to be premixed into the cylinder 1, and then reinstall the cover plate 2. Adjust the state of the cleaning mechanism 4 according to the premixing requirements. If only normal stirring is required, push the movable ring 401 along the stirring shaft 6 to the upper position by using the toggle plate 4021. When the movable ring 401 moves upward, it will drive the guide plate 404 to move synchronously. At this time, the two sets of sliders 405 will move towards the middle, which will cause the two sets of side scrapers 403 to move upward and move towards the middle synchronously. At this time, the two sets of bottom scrapers 408 will also move upward, so that the side scrapers 403 and bottom scrapers 408 do not contact the inner wall of the cylinder 1. Then use bolts 4022 to lock the movable ring 401 in the corresponding screw hole of the stirring shaft 6. If simultaneous wall scraping and cleaning is required, slide the movable ring 401 to the lower position so that the outer wall of the side scraper 403 is in contact with the inner wall of the cylinder 1 and the bottom of the bottom scraper 408 is in contact with the bottom inner wall of the cylinder 1. Then, lock the position of the movable ring 401 with the bolt 4022 to ensure the stability of the wall scraping process. During the premixing operation, start the variable frequency speed control motor 3. The output end of the motor 3 directly drives the high-strength alloy steel stirring shaft 6 to rotate stably. The stirring shaft 6 drives the movable ring 401 and related wall scraping components to rotate synchronously. The inclined design of the side scraper 403 and the bottom scraper 408 reduces the resistance of the raw materials and scrapes off the adhering raw materials on the inner wall and bottom of the cylinder 1 respectively, achieving full cavity cleaning, ensuring that the raw materials are fully mixed and improving the premixing uniformity. The connecting block 409 provides support for the bottom of the stirring shaft 6, further improving the rotational stability.

[0025] After cleaning, the waste material is poured out through the tipping mechanism 5. First, rotate the limiting screw 505 with the anti-slip knob on the inner wall of the concave plate 501 to disengage it from the insertion block 504 on the lower outer arc surface of the cylinder 1, thereby releasing the static lock of the cylinder 1. The operator holds the handle 503 and pushes the cylinder 1 to make the cylinder 1 rotate around the stainless steel rotating shaft 502 along the concave plate 501 to pour out the internal waste material. After the waste material is poured out, push the cylinder 1 in the opposite direction to reset it, and then insert the limiting screw 505 back into the insertion block 504 to lock it, so as to prevent accidental tipping during subsequent use.
