Internal mixing device for low-temperature-resistant sealing material and control method of internal mixing device

Abstract

The invention discloses an internal mixing device for a low-temperature-resistant sealing material and a control method of the internal mixing device. The internal mixing device has the characteristics of high production efficiency and high forming quality. According to the key point of the technical scheme, the internal mixing device comprises an internal mixer and a PLC control unit, wherein the PLC control unit is used for controlling the operation state of the internal mixer; the internal mixer comprises an internal mixing chamber; a screw is arranged in the internal mixing chamber; a feeding cavity and a top bolt assembly are arranged at the top of the internal mixing chamber; the top comprises two first oil cylinders installed above the internal mixing chamber; piston rods of the two first oil cylinders are connected through a cross beam; a second oil cylinder is arranged on the cross beam, and the lower end of a piston rod of the second oil cylinder is connected with a material pressing mechanism; and the material pressing mechanism comprises a main box body connected with the inner wall of the feeding cavity in a sliding manner and a pressing weight arranged at the bottom of the main box body; and a floating assembly used for controlling the pressing weight to float up and down is arranged in the main box body. The internal mixing device is suitable for the technical field of internal mixing devices.

Description

technical field [0001] The invention belongs to the technical field of banburying devices, in particular to a banburying device for low-temperature-resistant sealing materials and a control method thereof. Background technique [0002] Low-temperature resistant sealing materials mainly refer to rubber sealing materials suitable for low-temperature environments. Rubber materials are mainly mixed and formed through internal mixers. During the mixing process, various additives need to be added to improve the overall performance. [0003] Recently, according to the investigation of the actual use of internal mixers, people have gradually realized that during the internal mixing process, applying a floating pressure that can be automatically adjusted to the rubber material to be mixed in the internal mixing chamber can significantly improve product quality. And greatly improve production efficiency; that is to say, the pressing mechanism device has become a key component that dir...
