Description

Technical Field

[0001] The utility model relates to the technical field of silicone rubber production, in particular to a kneading device for pre-treating silicone rubber base material. Background Art

[0002] Silicone sealant is a paste made of polydimethylsiloxane as the main raw material, supplemented by cross-linking agents, fillers, plasticizers, coupling agents, and catalysts mixed under vacuum conditions. After pretreatment, the silicone sealant base material is obtained. During the pretreatment, a kneader is mainly used to disperse and mix the materials and additives. The dispersed and mixed powdered materials and additives form a base material with a certain initial viscosity.

[0003] During the operation of the vacuum kneader, the materials are mainly stirred, dispersed and mixed inside the vacuum kneader. After completing one dispersion and mixing, it is necessary to open the top cover first, and then control the vacuum kneader chassis to flip over as a whole, so that the opening of the vacuum kneader chassis flips 90°, which is convenient for discharging the pre-treated silicone rubber base material in the vacuum kneader chassis. Before discharging, a material receiving box or material receiving bucket should be equipped at the discharging position in advance.

[0004] Since both the top cover and the vacuum kneader chassis adopt a reversible structure, two hydraulic telescopic cylinders are required for separate control. Safety control needs to be carried out in the order of opening the top cover first and then opening the vacuum kneader chassis. If the operation is wrong, the equipment will be damaged by collision, causing unnecessary losses and reducing the safety of equipment operation. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-2 The utility model provides a technical solution: a kneading device for pretreatment of silicone rubber base material, comprising a kneading device body 1 and a cover plate 2 covering the kneading device body 1, a base 3 is provided at the bottom of the kneading device body 1, the kneading device body 1 is rotatably connected to the inside of the base 3, and a connecting shaft 4 is rotatably connected to the inside of the base 3, and the connecting shaft 4 is fixed on both sides of the kneading device body 1, one of the connecting shafts 4 is connected to a motor 5, and a supporting curved rod 6 is welded to the side of the kneading device body 1, and the supporting curved rod 6 is slidably connected to a connecting piece at the end away from the kneading device, and the end of the connecting piece away from the supporting curved rod 6 is fixed to the top of the cover plate 2.

[0021] The connecting member includes a vertical rod 7 welded to the top of the cover plate 2, and a connecting curved rod 8 is fixed to the end of the vertical rod 7 away from the cover plate 2. The end of the connecting curved rod 8 close to the supporting curved rod 6 is slidably connected to the supporting curved rod 6.

[0022] A sliding groove 9 is provided at the end of the connecting bent rod 8 close to the supporting bent rod 6 , and a top block 10 is fixed to the end of the supporting bent rod 6 close to the connecting bent rod 8 , and the top block 10 slides along the sliding groove 9 .

[0023] A fixing rod 11 is hingedly connected to the middle portion of the connecting curved rod 8 , and an end of the fixing rod 11 away from the connecting curved rod 8 is hingedly connected to a fixing seat 12 . The fixing rod 11 is fixedly connected to the base 3 .

[0024] The side surface of the fixing seat 12 is welded and fixed to the side surface of the kneading device body. A groove 13 is provided inside the fixing seat 12 , and the fixing rod 11 is hinged inside the fixing seat 12 .

[0025] When the fixing seat 12 rotates along with the kneading device body, the fixing rod 11 remains in a fixed state, that is, the fixing rod 11 remains in a vertical state.

[0026] The working principle of the present invention is as follows: when the motor 5 drives the connecting shaft 4 to rotate, the kneading equipment body 1 starts to rotate, and at the same time drives the supporting curved rod 6 to rotate. Since the shape of the supporting curved rod 6 remains stable, the top block 10 at the front end of the supporting curved rod 6 starts to slide along the slide groove 9 inside the connecting curved rod 8, and then contacts the connecting curved rod 8. The connecting curved rod 8 starts to rotate along the hinge point with the fixed rod 11. During the rotation, the connecting curved rod 8 is pressed downward by the top block 10 near the end of the supporting curved rod 6, and then the connecting curved rod 8 moves upward near the end of the cover plate 2, and then drives the cover plate 2 to move upward through the vertical rod 7 to open the cover plate 2. At the same time, as the rotation amplitude of the kneading equipment body increases, the opening angle of the cover plate 2 increases, thereby realizing the automatic opening of the cover plate 2.
