[0020] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

[0021] Unless otherwise defined, technical or scientific terms used in the present invention should have the common meanings understood by persons having ordinary skills in the field to which the present invention belongs.

[0022] The words "include" or "comprises" and the like used in the present invention mean that the elements before the word include the elements listed after the word, and do not exclude the possibility of also including other elements. The orientation or position relationship indicated by the terms "inside", "outside", "upper", "lower", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. When the absolute position of the described object changes, the relative position relationship may also change accordingly. In the present invention, unless otherwise clearly specified and limited, the terms "attachment" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] As attached Figures 1-2 As shown, the utility model discloses a rubber scraping device for a rubber mixing machine, comprising a fixing device 1 and a movable plate 2, wherein the movable plate 2 is arranged inside the fixing device 1, and the movable plate 2 can move left and right inside the fixing device 1, and the fixing device 1 is provided with an arc plate 4, which is a convex part of the fixing device 1 inside, and a guide shaft 3 of the movable plate 2 passes through the arc plate 4, and a toggle rod 5 is welded in the middle of the guide shaft 3, and the toggle rod 5 is convex in shape, so it cannot pass through the through hole of the arc plate 4 through which the guide shaft 3 passes, so the toggle rod 5 moves in the hollow part of the arc plate 4, and when the movable plate 2 swings left and right, the toggle rod 5 swings left and right inside the arc plate 4.

[0024] A scraper 7 is provided at the bottom of the fixing device 1 . The scraper 7 is connected to the fixing device 1 via a rotating bearing 8 . The rotating bearing 8 is fixedly connected at a recessed portion at the bottom of the fixing device 1 .

[0025] A fixed shaft 9 is provided at the edge of the blade of the scraper 7, and the fixed shaft 9 is connected to the toggle rod 5 through a spring 6. When the toggle rod 5 swings left and right inside the arc plate 4, the toggle rod 5 drives the fixed shaft 9 to swing left and right through the spring 6, so that the scraper 7 can change direction and the rollers 11 set before and after the rubber mixer 12 can be cleaned.

[0026] The top of the fixing device 1 is connected with a connecting plate 10 , and a cylinder 17 is arranged above the connecting plate 10 . The cylinder 17 drives the fixing device 1 to slide up and down, and the cylinder 17 is fixed under the safety plate 16 of the rubber mixer 12 .

[0027] The movable plate 2 is provided with a toggle buckle 14 on the outer side of the rubber mixing machine 12 for controlling the movable plate 2 to swing left and right.

[0028] Tracks 15 are provided on both sides of the rubber mixer 12 . When the spacing between the rollers 11 is adjusted by the roller adjusting disk 13 , the fixing device 1 can be slid down from the track 15 .

[0029] During the specific implementation process, the cylinder 17 is installed under the safety plate 16, and the cylinder 17 is started. The cylinder 17 drives the connecting plate 10 to move downward, so that the fixing device 1 slides downward in the track 15, and the roller adjustment disk 13 in the rubber mixer 12 adjusts the position between the two rollers 11 set in the front and rear. After the roller 11 completes the work, the toggle buckle 14 is used to adjust the swing of the movable plate 2, and the guide shaft 3 drives the toggle rod 5 to move left or right. Under the constraint of the arc plate 4, the toggle rod 5 is stuck at the edge of the arc plate 4. During this process, the spring 6 uses the fixed shaft 9 to adjust the position of the scraper 7, so that the scraper 7 can contact the roller 11, and the swing of the scraper 7 at the rotating bearing 8 can be adjusted left and right, so that the two rollers 11 set in the front and rear can be scraped.

[0030] Therefore, the utility model adopts the rubber scraping device of the rubber mixing machine, which solves the problem that the existing device cannot clean the rubber mixing machine and the manual cleaning efficiency is low.
