Abstract

The invention discloses a neck bush for high-precision temperature measuring extruder and a production process of the neck bush. The neck bush for the high-precision temperature measuring extruder comprises a temperature measuring probe and a neck bush body assembled into a machine shell. An embedded hole is formed in the outer side face of the neck bush body. The temperature measuring probe is fixedly mounted in the embedded hole. The production process comprises the steps that (1), the inner shape and the outer shape of the neck bush body are machined into the size of a finished product; (2), an embedded hole site is machined on the outer side face of the neck bush body; (3), a heat-conducting medium is added to the embedded hole; and (4), the temperature measuring probe is pressed into the embedded hole and fixed, and the neck bush for the high-precision temperature measuring extruder is obtained. By the adoption of the neck bush for the high-precision temperature measuring extruder, the accuracy of the material temperature control is improved, and the stability of the performance and quality of products in the production process is guaranteed; and furthermore, the production process has the beneficial effects that the mounting and operation are easy, and the production cost is low and has the good application and popularization value.

Description

technical field [0001] The invention relates to an extruder accessory, in particular to a high-precision temperature-measuring extruder inner bushing and a production process thereof. Background technique [0002] With the development of the polymer processing industry, more and more requirements are put forward for the molding and mixing process of polymer materials. In order to meet the requirements of the mixing process in polymer processing, especially hard polyvinyl chloride powder Parallel twin-screw extruders are widely used in the filling, blending, modification, reinforcement, devolatilization of chlorinated polypropylene and superabsorbent resins of rubber, plastics and engineering resins; degradable masterbatches, polyamide polycondensation , Extrusion of polyurethane polyaddition reaction; granulation of carbon powder and magnetic powder, insulation material for cables, sheath material, low-smoke, low-halogen flame-retardant PVC cable material and preparation of ...
