Embodiment 1

[0028] Example 1, such as Figure 1-3 As shown, a microinjection device includes an injection sleeve 5 , a piston 2 , a driving device 1 , a feeding hopper 3 and an exhaust valve 4 . Specifically, the injection sleeve 5 is coaxially provided with a hollow cavity with both ends open; the injection sleeve 5 is provided with a piston 2 extending from one end, and the piston 2 slides in the injection sleeve 5 to realize the adjustment of the injection sleeve. 5 pressure and extrusion of accessories. More specifically, the piston 2 is covered with a sealing ring and a guide ring to ensure the tight contact between the piston 2 and the inner wall of the injection sleeve 5 . More specifically, a connecting hole is coaxially arranged on the piston 2, and the piston rod 21 passes through the connecting hole, and the piston rod 21 and the piston 2 are connected together by a locking nut. More specifically, a guide sleeve is provided at the protruding end of the piston rod 21 of the in...

Abstract

The invention belongs to the technical field of blending and modifying equipment, and particularly relates to a micro-injection device which is used for adding auxiliary materials into a main pipeline in a mixing system based on a mixer. The micro-injection device comprises an injection sleeve, a piston, a driving device, a feeding hopper and an exhaust valve, wherein a hollow cavity is formed in the injection sleeve; the injection sleeve is coaxially sleeved with the piston; the driving device is used for driving the piston to slide along the injection sleeve; the end part of the injection sleeve is connected with a pipeline communicated with the main pipeline; and a switch valve is arranged between the feeding hopper and the injection sleeve. The piston is arranged in the injection sleeve, and the heating device is arranged outside the injection sleeve, so that the technical problem that an existing auxiliary material metering device is insufficient in pressurization and cannot add auxiliary materials into a high-pressure and high-viscosity melt pipeline is solved.

Description

technical field [0001] The invention belongs to the technical field of blending and modification equipment, and in particular relates to a micro-injection device. Background technique [0002] Plastic modification refers to the improvement of plastic quality through modification methods, such as density, hardness, precision, appearance, processability, transparency, mechanical properties, electromagnetic properties, chemical properties, corrosion resistance, aging resistance, wear resistance properties, thermal properties, flame retardancy, barrier properties and cost. Plastic modification is the most effective way to reduce costs and improve performance. [0003] Blending refers to mixing together. It is a physical method to uniformly mix several materials to improve material performance. In industry, it is typical to use rubber mixers to uniformly mix different rubber or rubber and plastics into rubber. For example, some special performance components can also be added t...
