Detailed Embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figure 1 - Figure 5As shown in the figure, a raw material kneader for aviation tire production with a kneaded material turning structure includes a kneader main body 1, a cylinder 20 and a scraper 23; the cylinder 20 and the fixed shell 21 are fixed by welding, and a gear 24 is rotatably connected to the inner wall of the fixed shell 21. The gear 24 is connected to a servo motor 22, and the gear 24 is sleeved on the output shaft of the servo motor 22. The gear 24 meshes with an arc-shaped rack 25. An activity groove 29 is opened inside the arc-shaped rack 25, and two groups of clamping grooves 30 are opened on the inner wall of the activity groove 29. A moving wheel 31 is slidably connected inside the activity groove 29. A groove 28 is opened on the inner wall of the scraper 23, and the inner wall of the groove 28 contacts the moving wheel 31. Sliders 26 are fixedly welded on both sides of the arc-shaped rack 25, and the sliders 26 are slidably connected inside a chute 27. The sliders 26 contact the inner wall of the chute 27, and the chute 27 is opened on the inner wall of the scraper 23;

[0024] During operation, for the kneaded material turning device of a kneader for tire production in the above technology, the rubber raw material is turned by the reciprocating movement of the scraper. However, the length of the scraper is fixed. During the turning process, only the part of the rubber raw material on the roller in contact with the scraper can be better turned. Through the structural design of the scraper 23 and the arc-shaped rack 25, the function of extending the arc-shaped rack 25 to the outside of the scraper 23, thereby increasing the length of the scraper 23, is realized. When it is necessary to extend the contact length between the scraper 23 and the roller of the kneader main body 1 for better rubber turning operation, first, the servo motor 22 drives the gear 24 to rotate. The gear 24 meshes with the arc-shaped rack 25. Therefore, the arc-shaped rack 25 will move on the scraper 23. Since sliders 26 are fixed on both sides of the arc-shaped rack 25 and the sliders 26 slide on the chute 27, the arc-shaped rack 25 can stably extend from the scraper 23. There is a moving wheel 31 sliding in the activity groove 29, and the rotating shaft part of the moving wheel 31 slides in the clamping groove 30. When the moving wheel 31 abuts against the inner wall of the groove 28, the arc-shaped rack 25 cannot move at this time, so as to limit the moving range of the arc-shaped rack 25 on the scraper 23. Among them, the forward and reverse rotation of the servo motor 22 can be used to control the upward or downward movement of the scraper 23.

[0025] Furthermore, two groups of storage grooves 32 are opened inside the arc-shaped rack 25. The storage grooves 32 are located on both sides of the activity groove 29. A plurality of springs 34 are fixedly welded on the inner wall of the storage groove 32. The springs 34 and the arc-shaped plate 33 are fixed by welding;

[0026] During operation, through the structural design of the arc-shaped plate 33 and the spring 34, when the arc-shaped rack 25 extends outwards, when the arc-shaped plate 33 no longer contacts the inner wall of the scraper 23, under the action of the spring 34, the arc-shaped plate 33 will be ejected into the storage groove 32. At this time, the arc-shaped rack 25 can contact the roller on the mixer main body 1 through the arc-shaped plate 33, so that the extended arc-shaped rack 25 can effectively turn the rubber raw material on the roller. There are two groups of arc-shaped plates 33 and they are located on both sides of the movable groove 29. Therefore, during the process of the scraper 23 and the arc-shaped rack 25 turning the rubber raw material, the arc-shaped plate 33 can effectively prevent the rubber raw material from entering the interior of the movable groove 29.

[0027] Furthermore, a gasket 35 is adhesively fixed on the inner wall of the groove 28, and the gasket 35 is made of rubber material;

[0028] During operation, since the gasket 35 is made of rubber material, it buffers between the inner wall of the groove 28 and the moving wheel 31, thereby reducing the wear generated when the moving wheel 31 abuts against the inner wall of the groove 28.

[0029] Furthermore, the servo motor 22 is welded and fixed on the inner wall of the fixed shell 21. Four groups of pulleys 36 are welded and fixed at the bottom end of the fixed shell 21, and the pulleys 36 are slidably connected to the long groove 37, and the long groove 37 is opened on the support plate 38;

[0030] During operation, the servo motor 22 is fixed inside the fixed shell 21 to protect the servo motor 22. Through the design of four groups of pulleys 36 at the bottom end of the fixed shell 21, the fixed shell 21 can move stably.

[0031] Furthermore, the bottom end of the air cylinder 20 is welded and fixed on the support plate 38, and the support plate 38 is fixed to the front end of the mixer main body 1 by screws;

[0032] During operation, the air cylinder 20 is fixed on the support plate 38 to prevent it from moving during operation, and the bottom end of the support plate 38 is fixed to the mixer main body 1 by screws, which is convenient for installation and disassembly.

[0033] Furthermore, the scraper 23 and the fixed shell 21 are fixed by welding, and inclined surfaces are provided at the top and bottom ends of the arc-shaped plate 33;

[0034] During operation, the scraper 23 and the fixed shell 21 are an integral body. The inclined surfaces provided at the top and bottom ends of the arc-shaped plate 33 facilitate the arc-shaped plate 33 to be smoothly received into the storage groove 32 when the arc-shaped rack 25 is retracted.

[0035] Working principle: In a mixing material turning device for a rubber mill in the prior art, the rubber raw material is turned by the reciprocating movement of a scraper. However, the length of the scraper is fixed. During the turning process, only the part of the rubber raw material on the roller in contact with the scraper can be turned well. In this case, a raw material kneader for aircraft tire production with a mixing material turning structure realizes the function of easily extending the arc-shaped rack 25 to the outside of the scraper 23, thereby increasing the length of the scraper 23 through the structural design of the scraper 23 and the arc-shaped rack 25. When it is necessary to extend the contact length between the scraper 23 and the roller of the kneader main body 1 for better rubber turning operation, first, the servo motor 22 drives the gear 24 to rotate. The gear 24 meshes with the arc-shaped rack 25. Therefore, the arc-shaped rack 25 will move on the scraper 23. Since sliders 26 are fixed on both sides of the arc-shaped rack 25 and the sliders 26 slide on the chute 27, the arc-shaped rack 25 can stably extend from the scraper 23. A moving wheel 31 slides in the movable groove 29, and the rotating shaft part of the moving wheel 31 slides in the card slot 30. When the moving wheel 31 abuts against the inner wall of the groove 28, the arc-shaped rack 25 cannot move at this time to limit the moving range of the arc-shaped rack 25 on the scraper 23. Among them, the up and down movement of the scraper 23 can be controlled by the forward and reverse rotation of the servo motor 22.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, similar improvements, etc. made within the scope of the theory and principles of the present invention shall be included within the scope of protection of the present invention.
