Description

Technical Field

[0001] This utility model relates to the field of conductive silicone rubber processing, specifically a conductive silicone rubber raw material drying device. Background Technology

[0002] Conductive silicone rubber is made by compounding and vulcanizing silicone rubber as a base rubber with the addition of conductive fillers, crosslinking agents, etc. The commonly used rubber compound is methyl vinyl silicone rubber, and the commonly used conductive fillers include acetylene black, carbon fiber, superconducting carbon black, graphite, copper powder, silver powder, aluminum powder and zinc powder. Compared with general conductive rubber, conductive silicone rubber has the advantages of low volume resistivity, low hardness, resistance to high and low temperatures, aging resistance, and good processing and manufacturing performance. It is particularly suitable for manufacturing conductive silicone rubber products with good conductivity, complex shape and fine structure.

[0003] Existing technologies for drying conductive silicone rubber raw materials still have certain shortcomings in use. Since conductive silicone rubber raw materials are usually laid flat on the conveying mechanism for transport, the bottom surface of the conductive silicone rubber raw materials is not easy to dry, which increases the drying time. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for conductive silicone rubber raw materials, in order to solve the problem mentioned in the background art that the bottom surface of the conductive silicone rubber raw materials is not easy to dry due to the fact that they are usually laid flat on the conveying mechanism for conveying, which increases the drying time.

[0006] In a further embodiment, the deflecting air duct is designed as a trapezoidal structure, and the deflecting air duct is fixedly connected to the main body of the conductive silicone rubber raw material dryer by bolts.

[0007] In a further embodiment, the two sides of the upper inclined conveyor are fixedly connected to the main body of the conductive silicone rubber raw material dryer by bolts, and the support frame is connected to the upper inclined conveyor by welding.

[0008] In a further embodiment, the telescopic pipe and the deflecting air supply pipe are fixedly connected by threads, and the surface of the telescopic pipe is provided with multiple punches.

[0009] In a further embodiment, the hot air outlet is fixedly connected to the heater by a snap fastener, and the hot air outlet is rectangular in shape.

[0010] In a further embodiment, the deflecting air duct and the heater are fixedly connected by a connecting rod, the top end of the connecting rod is fixedly connected to the heater by a thread, and the bottom end of the connecting rod is fixedly connected to the deflecting air duct by a plug.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By assembling the upper and lower inclined conveyors together, the conductive silicone rubber material can be transported along a curved path, first from bottom to top and then from top to bottom. During the transition, the bottom surface of the conductive silicone rubber material can be loosened to facilitate the entry of hot air into the bottom surface. Rollers are installed inside the lower inclined conveyor, and the conductive silicone rubber material is allowed to slide down quickly from a height using the action of gravity and friction. The roller design allows for better ventilation at the bottom surface of the lower inclined conveyor, facilitating contact between hot air and the bottom surface of the conductive silicone rubber material, thereby increasing the drying speed of the conductive silicone rubber material. The structure is simple and easier to operate. Attached Figure Description

A heater 2 is used to increase the heat inside the main body 1 of the conductive silicone rubber raw material dryer. A hot air outlet 4 is used to blow out hot air. A deflecting air pipe 6 is used to change the direction of hot air delivery. A telescopic pipe 7 is used to adjust the length of the hot air outlet.

[0019] The directional air duct 6 is designed in a trapezoidal shape and is fixedly connected to the main body 1 of the conductive silicone rubber raw material dryer by bolts. The trapezoidal structure makes the connection position of the directional air duct 6 with the upper inclined conveyor 8 and the lower inclined conveyor 9 more coordinated.
