[0002] The mixer for silicone rubber production is a key device specifically used for mixing and preparing silicone rubber materials. As a high-performance material, silicone rubber is widely used in the fields of electronics, automobiles, medical treatment, and daily necessities. Its production process has extremely high requirements for the mixing equipment, and it is necessary to ensure the full mixing of materials, uniform stirring, and stable production efficiency.

[0003] In the existing mixers for silicone rubber production, generally, raw materials are placed in a mixing barrel, and then the mixing mechanism is inserted into the raw materials for mixing. Such a mixing method will result in a fixed mixing position, and due to the high viscosity of the raw materials, the mixing effect of the raw materials will be affected, resulting in a long mixing time of the raw materials and a reduction in the production efficiency of silicone rubber. In view of this, we propose a mixer for silicone rubber production. Content of the Utility Model

There is a rotatable connection between the bottom of the inner wall of the chassis frame and the side of the support frame close to it by an electric push rod. Between the two sides of the top of the support frame, several driving rollers are rotationally installed. At the bottom of the support frame, a driving mechanism fixedly connected to the rear end of the driving roller is installed. A mixing barrel is fitted between two adjacent driving rollers;

[0006] The mixing barrel includes a barrel body and a barrel cover. On the side of the barrel cover inside the barrel body, a spiral blade is fixedly provided, and the outer edge of the spiral blade is in contact with the inner wall of the barrel body.

[0007] Through the cooperation of the rotationally installed support frame and the electric push rod, the utility model can adjust the inclination angle of the driving roller, so that the angle of the mixing barrel placed between two adjacent driving rollers changes, facilitating the flow of the raw materials inside the mixing barrel. With the setting of the driving mechanism, the two driving rollers can rotate, and under the influence of friction, the mixing barrel is controlled to rotate, achieving the effect of rotational mixing. With the spiral blade structure on the barrel cover, the raw materials can be divided and fused, further improving the mixing effect of the raw materials. In this way, under the synchronous operation of rotation and flipping, the mixing effect of the raw materials can be enhanced, and the fluidity of the raw materials in the mixing barrel is improved.

[0008] Preferably, a stirring member is provided through the middle of the bucket cover, and a driving member inserted into the stirring member is movably provided on the front side of the support frame.

[0009] Preferably, the stirring member includes a rotating rod. A plurality of stirring blades are annularly arranged on the rod wall of the rotating rod located inside the barrel body. Two limiting rings respectively fitting with the inner and outer side walls of the bucket cover are fixedly provided on the side rod wall of the rotating rod, and a hexagonal block is fixedly provided at the outer end of the rotating rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By the cooperation of the rotatably installed support frame and the electric push rod, the inclination angle of the driving roller can be adjusted in the present utility model, so that the angle of the stirring barrel placed between two adjacent driving rollers changes, which is convenient for the raw materials inside the stirring barrel to flow. With the setting of the driving mechanism, the two driving rollers can rotate, and under the influence of friction, the stirring barrel is controlled to rotate, achieving the effect of rotational mixing.

[0026] In an embodiment of the present utility model, the stirring member 8 includes a rotating rod 801. A plurality of stirring blades 802 are annularly arranged on the rod wall of the rotating rod 801 located inside the bucket body 701. Two limiting rings 803 respectively fitting with the inner and outer side walls of the bucket lid 702 are fixedly disposed on the side end rod wall of the rotating rod 801, and a hexagonal block 804 is fixedly disposed at the outer end of the rotating rod 801; the rotating rod 801 and the stirring blades 802 are integrally connected, and the connection position is an arc angle, which can reduce the problem of difficult cleaning of the right-angle dead corners. The setting of the two limiting rings 803 can limit the position where the rotating rod 801 is combined with the bucket lid 702 without affecting the rotation.

[0027] In an embodiment of the present utility model, the driving member 9 includes a fixing plate 901. A driving motor 902 is installed on the plate wall of the fixing plate 901, and a hexagonal sleeve 903 combined with the hexagonal block 804 is installed at the output end of the driving motor 902; the connection between the hexagonal sleeve 903 and the hexagonal block 804 can combine the driving motor 902 with the rotating rod 801, so as to control the rotation of the rotating rod 801.

[0028] In an embodiment of the present utility model, a T-shaped plate 904 fixedly connected to the support frame 3 is movably installed on the plate wall of the fixing plate 901, and a limiting pin fitting with the fixing plate 901 is inserted into the plate wall of the T-shaped plate 904; the combination of the T-shaped plate 904 passing through the fixing plate 901 and the support frame 3 can facilitate the adjustment of the position of the fixing plate 901.

[0030] In an embodiment of the present utility model, two bearing seats 2 aligned with the middle of the support frame 3 are fixedly disposed on the inner wall of the chassis frame 1, and fixing rods connected to the bearing seats 2 are fixedly disposed on both side edges of the support frame 3; the structures of the two can make the support frame 3 achieve a flip effect.

[0031] Working principle: This embodiment provides a mixer for silicone rubber production. When in use, first place the mixing barrel 7 filled with raw materials between two adjacent driving rollers 5, so that the rear end of the mixing barrel 7 fits against the baffle 301. Then, the driving member 9 can be moved so that the hexagonal sleeve 903 on the driving motor 902 is combined with the hexagonal block 804 on the side end of the rotating rod 801, thereby fixing the placement position of the mixing barrel 7. After completion, the driving mechanism 6 can be started to control the rotation of the driving roller 5. Under the action of friction, the mixing barrel 7 can be driven to rotate, causing the raw materials inside to be turned and mixed. During the rotation, the electric push rod 4 can be started to tilt the mixing barrel 7 driven by the support frame 3, so that the raw materials inside flow obliquely. While the raw materials are flowing and mixing, the raw materials can be divided by the spiral blade 703 structure provided on the barrel cover 702, thereby further improving the mixing effect of the raw materials. In addition, the driving member 9 can be started to drive the mixing member 8 to rotate in the reverse direction, so as to stir the raw materials in the mixing barrel 7, thereby further improving the mixing effect of the raw materials. Through such a structural cooperation, the mixing speed of the raw materials can be increased, the processing time can be reduced, and it is convenient to use.
