Embodiment 1

[0082] Such as figure 1 As shown, a disc mixer of the present invention includes a mixer main body 1, a power system 2, a transmission component 3, a strip conveying device 4 and a frame 5; wherein the transmission component 3 transmits the power provided by the power system 2 Give mixer body 1. The mixer main body 1 and the power system 2 are mounted on the frame 5 . The strip conveying device 4 is located below the mixer main body 1 and installed on the frame 5 .

[0083] Such as figure 2 Shown, the mixer main body 1 in a kind of disc type mixer of the present invention (serial number sees figure 1 ) connection and installation relations are as follows:

[0084] A screw rod 8 is sleeved in the rotating body 7 of the moving disk, and the screw rod 8 is fixed on the fixed disk 10 through the screw rod mounting screw 9 . The fixed plate 10 is covered with a fixed plate return ring 11 . A bearing housing 12 , a seal 13 , a bearing 14 , a spacer ring 15 , a bearing 2 16 , ...

Embodiment 2

[0098] Such as figure 2 As shown, in order to accurately adjust the gap between the end surface of the rotating body 7 of the moving disk and the upper surface of the fixed disk 10 to meet the processing requirements of different materials, the main body of the present invention also includes a gap adjustment device. In the following, this embodiment will describe in detail the composition of the gap adjustment device and the specific working process of the gap adjustment.

[0099] First, the gap adjustment device includes a depth gauge 20 and a gap adjustment bolt 21 . In the present invention and the embodiment, the locking of the bearing lock nut 17 makes the rotor 7, the bearing housing 12, the seal 13, the first bearing 14, the spacer ring 15, and the second bearing 16 integrated. The specific gap adjustment process is as follows:

[0100] Before the gland mounting screw 26 is tightened, use the gap adjustment bolt 21 to adjust the gap between the end surface of the ro...

Embodiment 3

[0103] The present invention can also adjust the gap between the end surface of the rotor rotating body and the upper end surface of the fixed disk by adding gaskets, and the specific implementation is as in the present invention and the embodiments Figure 9 shown.

[0104] Specifically, the method of increasing the gasket 51 is used to adjust the rotating disc rotating body 7 (serial number is the same as figure 2 ) end face and fixed plate 10 (serial number is the same as figure 2 ) gap between the upper end faces, the specific process is:

[0105] Place some spacers on the machine barrel 19 (serial number is the same as figure 2 ) and bearing housing 12 (the same serial number figure 2 ) between the bosses, as the number and height of the gaskets increase, the bearing housing 12 (serial number is the same as figure 2 ) to rise upwards to drive the moving plate rotating body 7 (serial number is the same as figure 2 ) and the parts on it rise as a whole, and the m...

Abstract

The invention discloses an abrasive disc type mixer and belongs to the field of polymer blending equipment. The mixer consists of a mixer main body, a power system, a transmission component, a material strip conveying device and a rack, wherein the mixer main body is used for fusion, plastification, mixing and extrusion; the power system provides the mixer main body with power; the transmission component transmits the power of the power system to the mixer main body; the material strip conveying device conveys and cools material strips extruded by the mixer main body; and the rack has supporting and locating functions. When the mixer main body works, a screw rod and a fixed disc in the mixer main body are still, but a moving disc rotating body rotates. The screw rod plays a role of conveying and compacting materials, and the moving disc rotating body moves relative to the fixed disc and plays a mixing role. The mixed material flows into a moving disc material collecting tank and is extruded into the strips by a fixed disc discharging opening. An abrasive disc clearance can be adjusted by a clearance adjusting device or a pad. The mixer main body considers bearing sealing and has a temperature controlling function. The abrasive disc type mixer can be used for the blending modification processing process of a polymer-based material.

Description

technical field [0001] The invention provides a disc mixer, which can be used for melting, plasticizing, mixing and extrusion processing of polymer-based materials, and belongs to the field of polymer blending equipment. Background technique [0002] Compounding is an essential process in polymer processing. With the increasing demand for high-performance and high-quality polymer materials, the requirements for further improvement of mixing equipment are also put forward. In the past ten years, designers have cleverly combined traditional stone mills and screw extruders to develop various types of continuous mixing equipment with high shear and dispersion capabilities. After data retrieval, the mixing equipment that uses this design idea mainly includes the following types: [0003] 1 Huang Liping et al. published the title "A Kind of End Face Mixing Extruder" (published in "China Plastics" Vol. Install the fixed plate on the fixed structure opposite the moving plate. Wh...
