Problems solved by technology

However, the temperature of the powder will increase due to the stirring blades in the process of stirring, and due to the characteristics of the polytetrafluoroethylene material itself, it will easily bond into agglomerates as the temperature increases, so that the existing mixing During the mixing process of the machine, it is easy to affect the uniformity of the mixture, which in turn affects the yield of the final product

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] see Figure 1 ~ Figure 3 , a mixer, used for mixing powder, especially for stirring and mixing polytetrafluoroethylene powder. It includes a mixing mechanism 1 and is arranged on a frame 2. The mixer also includes a main driving device 3 , an auxiliary driving device 4 , a cooling mechanism 5 , a feeding mechanism 6 , a filtering mechanism 7 and an air storage tank 8 .

[0024] see Figure 4 The mixing mechanism 1 includes a barrel body 11 and a cover body 12 for closing the barrel body 11. The barrel body 11 is used to contain polytetrafluoroethylene powder, and the barrel body 11 is used for stirring and mixing. The lid body 12 is hinged on the barrel body 11 and can be connected with the lid body driving mechanism 13. The lid body driving mechanism 13 can preferably be an air cylinder, so that the lid body 12 can be opened and clo...

Abstract

The invention discloses a mixing machine, which comprises a mixing mechanism and a main driving device. The mixing mechanism includes a barrel for containing powder, and a bottom for stirring the powder is arranged in the bottom of the barrel. A mixing disc, the mixing disc includes a transmission shaft and a plurality of first paddles connected to the transmission shaft and capable of rotating with the transmission shaft, characterized in that: the main driving device includes a frequency conversion main A motor, the main motor is connected to the transmission shaft and can drive the transmission shaft to rotate. By setting the main motor with frequency conversion, it can be controlled to run at different speeds during mixing, so that by adjusting the stirring speed of the mixing blades and maintaining a certain intermittent time, it can avoid the rapid rise of powder temperature caused by continuous high-speed rotation , so as to ensure the uniformity of the mixture.

Description

technical field [0001] The invention relates to a powder stirring device, in particular to a powder mixing mixer. Background technique [0002] In the suspension system, the elastic elements vibrate due to the impact. In order to improve the smoothness and comfort of the car, a shock absorber is installed in parallel with the elastic elements in the suspension. When there is relative motion between the frame and axle due to vibrations, the piston in the shock absorber moves up and down. Due to the frequent relative movement between the piston and the shock absorber cylinder, it is necessary to coat the surface of the piston with a wear-resistant and low-friction material (lamination), such as polytetrafluoroethylene, to prolong the service life. [0003] PTFE products have good wear resistance, pressure resistance, low friction coefficient and other characteristics, and are sintered by cold pressing of molds. Mixing is the basic process in the manufacture of PTFE products,...
