Vulcanizing machine with exhaust and expansion mechanism

Abstract

The invention discloses a vulcanizing machine with an exhaust and expansion mechanism. An exhaust mechanism is arranged at the discharging end, wherein an exhaust hood can be adjusted in a lifting mode according to the height of a product to ensure the exhaust effect. The exhaust hood is matched with an exhaust passage through an organ hood to prevent exhaust gas from overflowing while the liftingadjustment is realized. An expansion part seals both ends of the expansion position of a heat-shrinkable tube workpiece through two sets of clamping transmission assemblies, so that the expansion gasis always left at the expansion position, and the heat-shrinkable tube workpiece does not need to be ventilated at all times, so that the wall thickness of each position of a heat-shrinkable tube after expansion is ensured to be consistent, the stability of the expansion process is improved, the expansion effect is ensured, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a vulcanizer with exhaust and expansion mechanism. Background technique [0002] During the production of the heat-shrinkable tube, it needs to be discharged through the extruder and the molding equipment, and then vulcanized by the vulcanization equipment, and finally expanded and formed by the expansion machine; the existing vulcanization equipment will bring out a large amount of waste gas at the outlet of the vulcanization channel. To cause pollution, it is necessary to set up an exhaust channel, and if the exhaust channel is set too high, the exhaust effect will not be good, if it is set too low, it may affect the discharge; and the existing expansion equipment has low efficiency and poor expansion effect , often resulting in inconsistent wall thickness after expansion. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a vulcanizer wit...
