2results about How to "Accelerated cooling and solidification" patented technology

The utility model relates to the field of TPU film extrusion molding, specifically discloses a TPU film extrusion head, extrusion mould is used for TPU film extrusion molding, and the extrusion mould includes the mould of upper and lower symmetry, and the flow channel for the film raw material in the molten state is formed between two moulds and passes, side plate is provided with two and is fixed in the left and right sides of extrusion mould respectively, and the side plate is used for blocking the left and right sides opening of flow channel, heat dissipation subassembly is provided with two and is fixed in the upper and lower sides of extrusion mould respectively, and the heat dissipation subassembly includes the casing and heat dissipation structure, and the left and right side edges of casing respectively with the side plate of left and right sides abut, the utility model discloses through multiple heat dissipation fins in heat dissipation structure and the abutment of mould surface, first air inlet pipe blows the airflow to heat dissipation fin, to accelerate the heat transfer of extrusion head film forming position place, thus accelerates the film cooling solidification, to make the extrusion head guarantee higher extrusion speed while ensuring the film forming quality, thereby improve the film extrusion molding efficiency.

The utility model relates to the technical field of junction box processing, in particular to a junction box welding shaping auxiliary device which comprises a machine frame, an air blower fixedly arranged on the surface of the machine frame, a communicating pipe inserted into the top end of the air blower, a three-way pipe inserted into the side wall of the machine frame, and a sliding rail fixedly arranged on the side wall, close to the upper portion of the three-way pipe, of the machine frame. A sliding seat is movably connected to the side wall of the sliding rail, and two first electric push rods are fixedly arranged on the side wall of the sliding seat; compared with a traditional junction box welding shaping auxiliary device, the first support and the metal pipe are matched to improve the mounting and positioning precision of the metal pipe, the sliding rail is started, and the first electric push rod and the second electric push rod can drive the metal pipe to synchronously move along with the welding head; wind power can be generated by starting the air blower and sprayed out through the communicating pipe, the three-way pipe, the plastic pipe and the metal pipe, so that the junction box welded junction and the welding head are blown, cooling and solidification of the welded junction are accelerated, and the quality and efficiency of junction box welding shaping are improved.
