Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a mixing device for silicone rubber foam raw materials. Background Art

[0002] Silicone rubber foam is a lightweight porous material obtained by foaming silicone rubber. It has good elasticity and temperature resistance and is widely used in the fields of electronics, electrical, automotive, construction and medical. When making silicone rubber foam, it is necessary to evenly mix a variety of raw materials such as base rubber, fillers, catalysts, stabilizers, etc. in a certain proportion to provide a prepared mixed material for the subsequent foam molding process. In order to ensure stable stirring, the existing mixing device for silicone rubber foam raw materials needs to place the mixing barrel stably on the table, which causes the mixing barrel to be fixed during the stirring process, resulting in the flow of raw materials in the mixing barrel being restricted. Although the agitator can stir the raw materials, due to the fixation of the barrel body, the flow path and mixing mode of the raw materials are limited, resulting in uneven mixing effect and low efficiency. To this end, the utility model proposes a mixing device for silicone rubber foam raw materials. Utility Model Content

A second motor 8 is fixedly provided at the port of the storage barrel 6 through a support frame, and a stirring rod 9 is fixedly provided at the output end of the second motor 8, and the stirring rod 9 is located inside the storage barrel 6, so as to facilitate uniform stirring of the internal raw materials; a positioning component 10 is provided at the bottom of the storage barrel 6 for support, and a connecting seat 11 is rotatably provided at the bottom of the positioning component 10 through a connecting block. The connecting seat 11 is fixedly connected to the upper surface of the bottom plate 3, which can make the rotation of the storage barrel 6 more stable.

[0029] like Figures 1 to 4 As shown, the driving assembly 5 includes a support ring 51, the inner ring surface of the support ring 51 is provided with a guide groove 52, and the internal rotation of the guide groove 52 is provided with a gear ring 53, which can guide the gear ring 53, and the inner ring surface of the gear ring 53 is fixedly provided with a fixing ring 54, which can limit the gear ring 53 so that the gear ring 53 rotates more stably in the guide groove 52, and the inner ring surface of the fixing ring 54 is fixedly provided with two sliding blocks 57, and the sliding blocks 57 are symmetrically arranged. The sliding blocks 57 are slidably connected to the slide groove 7, which can stably guide the storage barrel 6, and a first motor 55 is fixedly installed on the support ring 51, and the output end of the first motor 55 is fixedly connected to a gear 56, which is meshed with the gear ring 53 to facilitate driving the storage barrel 6 to rotate.

[0030] like Figure 1 and Figure 3As shown, the positioning assembly 10 includes a fixed disk 101, and a placement groove 102 is provided at the upper end of the fixed disk 101, and the placement groove 102 can clamp the bottom of the storage barrel 6 to each other to avoid displacement during rotation. A sliding groove 103 is provided on the inner ring surface of the placement groove 102, and there are two sliding grooves 103, which are symmetrically arranged. A clamping block 104 is slidingly provided inside the sliding groove 103, which can guide the clamping block 104 so that the clamping block 104 can move and clamp the storage barrel 6 more stably. An adjusting rod 105 is rotatably provided on one side of the clamping block 104, and one end of the adjusting rod 105 is fixedly connected to a rotating handle for manual rotation of the adjusting rod 105. The adjusting rod 105 is threadedly connected to the fixed disk 101, which is convenient for pushing the clamping block 104 to fix and clamp the storage barrel 6, thereby ensuring the stability of the rotation of the storage barrel 6.

[0031] Furthermore, the storage barrel 6 is tilted, which can ensure that the raw materials inside the storage barrel 6 are shaken during the rotation process, thereby improving the stirring efficiency.

[0032] Secondly, the clamping block 104 is arranged in an arc-shaped structure, which is convenient for mutual engagement with the outer wall of the storage barrel 6 to position the clamping block 104 .

The output end of second motor 8 drives stirring rod 9 to rotate, stirring the silicone rubber foam raw material in storage barrel 6. During the stirring process, first motor 55 is driven, which drives gear 56 to rotate. Gear 56 engages with gear ring 53 to rotate gear ring 53, which in turn drives fixed ring 54 to rotate. Fixed ring 54, via sliding block 57, drives storage barrel 6 to rotate. The rotation of storage barrel 6 causes the silicone rubber foam raw material inside to shake, causing the mixing barrel to rotate in a circular motion during the stirring process. This circular motion increases the fluidity and contact area of the raw material within the mixing barrel, resulting in more complete stirring, improved uniformity of the mixture, and enhanced stirring efficiency.

[0035] Furthermore, the storage barrel 6 drives the positioning assembly 10 to rotate during the rotation process, and the positioning assembly 10 drives the bottom plate 3 to rotate in the guide groove 2 through the connecting seat 11, thereby ensuring the stability of the storage barrel 6 in the circular movement.

[0036] Furthermore, after the storage barrel 6 is evenly stirred, the adjusting rod 105 is rotated to move away from the storage barrel 6, and the adjusting rod 105 drives the clamping block 104 to move horizontally in the sliding groove 103. Then, the storage barrel 6 is tilted upward, so that the sliding groove 7 on the side of the storage barrel 6 slides with the sliding block 57, and the storage barrel 6 is removed, making it easier to disassemble and assemble the storage barrel 6, remove the raw materials, or clean the storage barrel 6.

[0037] The above specific embodiments are merely several optional embodiments of the present invention.
