[0002] Open mixing mill, also known as open rubber mixing mill, is a kind of mechanical equipment mainly used for processing and producing rubber, plastic and polymer materials. Its main components include frame, roller, pitch adjustment device and transmission device.

[0003] At present, in the rubber production process, the mixing mill is one of the commonly used equipment. During the rubber production process, it is easy for the edge rubber to be squeezed into the roller of the mixing mill. The cooked rubber accumulated for a long time will be mixed with other rubbers to cause rubber beans, affecting the quality of the rubber.

[0004] At present, the existing open mixing mill often adopts the method of setting a baffle plate at the upper edge position of the roller to prevent the colloid from alternately entering the edge of the roller of the open mixing mill. However, in actual use, since the colloid will move to both sides after being subjected to force, and the baffle plate cannot completely contact all positions of the edge of the roller, some of the colloid will still alternately squeeze into the edge position. Therefore, a small scraper device for an open mixing mill is proposed to solve the above problem. Utility Model Content

The number of the clamping blocks 55 is set to two, and the top view of the clamping block 55 is a right-angled trapezoid, and the inclined surface of the clamping block 55 is set at the front end. The ends of the two clamping blocks 55 that are away from each other are elastically connected to the inner wall of the mounting groove 54 by a spring 59, and one end of the spring 59 is fixedly connected to the ends of the two clamping blocks 55 that are away from each other, and the other end of the spring 59 is fixedly connected to the inner wall of the mounting groove 54.

[0037] Reference Figure 4 - Figure 6A control slot 56 is provided at the top of the block 55, and a control rod 57 is slidably connected to the inner wall of the mounting slot 54. The bottom end of the control rod 57 is set to a triangle, and the shape of the bottom end of the control rod 57 matches the control slot 56.

[0038] Reference Figure 2 - Figure 3 A pushing assembly 6 is provided inside the main body 1 of the mixing mill, and the pushing assembly 6 includes an air pressure chamber 61. The air pressure chamber 61 is opened on the inner wall of the edge shell part of the main body 1 of the mixing mill, and the front end of the air pressure chamber 61 is consistent with the top of the blade 4. By setting different heights, it is ensured that motion interference can be generated between objects at different heights. The inner wall piston of the air pressure chamber 61 is connected with a push plate 62, and the inner wall piston of the air pressure chamber 61 is connected with a material control plate 63. The moving direction of the material control plate 63 is consistent with the inclination angle of the blade 4.

[0039] Reference Figure 2 - Figure 3 The mounting block 51 is provided with a starting assembly 7 inside, which includes an air pressure chamber 2 71. The top end of the rear end of the air pressure chamber 1 61 is consistent with the top end of the starting block 74. The air pressure chamber 2 71 is opened on the inner wall of the mounting block 51. The inner wall piston of the air pressure chamber 2 71 is connected with a force block 72. The cross-sectional shape of the force block 72 is triangular, and the inclined surface of the force block 72 is arranged at the lower side of the front end. Through the force block 72, it is ensured that when the force block 72 is subjected to an upward or backward force, it can be displaced to achieve a protective effect. The rear end of the force block 72 is elastically connected to the inner wall of the air pressure chamber 2 71 through a spring 4 73. One end of the spring 4 73 is fixedly connected to the rear end of the force block 72, and the other end of the spring 4 73 is fixedly connected to the inner wall of the air pressure chamber 2 71. The inner wall piston of the air pressure chamber 2 71 is connected with a starting block 74.

[0040] Working principle: When in use, the staff first puts the connecting block 52 into the opening at the front end of the mounting plate 2. During installation, the outer wall of the connecting block 52 first pushes the inclined surface of the card block 55, so that the card block 55 moves to the inside of the mounting groove 54. When the connecting block 52 continues to move, when it moves to the point where the bayonet 53 is completely at the same horizontal position as the card block 55, the card block 55 enters the bayonet 53 driven by the spring 59, thereby fixing the position of the mounting block 51 and achieving the effect of fixing the blade 4.

[0041] After the installation is completed, the staff uses the equipment normally. When the colloid moves to a position close to the edge, the colloid can be scraped away from the edge of the roller by the blade 4, and moved toward the middle driven by the inclined surface of the blade 4.

[0042] When the colloid accumulates too much and does not move, the colloid squeezes the force-bearing block 72, causing the force-bearing block 72 to move toward the direction of entering the air pressure chamber 2 71, thereby increasing the air pressure on the inner wall of the air pressure chamber 2 71, thereby causing the starting block 74 to move.

[0043] When the starting block 74 moves, the starting block 74 pushes the push plate 62, thereby increasing the air pressure inside the air pressure chamber 61, so that the material control plate 63 moves outward, thereby pushing the colloid at the front end of the blade 4 to the inner side of the baffle 3, thereby preventing too much colloid from entering the edge of the roller due to accumulation.

[0044] After use, if the staff needs to disassemble the blade 4 for maintenance, the staff presses the reset plate 58 downward, so that the reset plate 58 drives the control rod 57 to move downward, so that the triangular area at the bottom end of the control rod 57 enters the control groove 56, so that the blocking block 55 moves in a direction away from each other. At this time, the connecting block 52 is not restricted, and the staff can smoothly take out the installation block 51, thereby taking out the blade 4.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
