Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
In the figure: the device comprises a base 1, a charging barrel 2, a charging opening 21, a control box 3, a microwave generator 4, a first shell layer 5, a second shell layer 6, an extrusion head 7, a heating mechanism 8, an emission part 9, a screw rod 10, a third shell layer 11, a fixing column 12 and a power motor 13.
The specific implementation mode is as follows:
the following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.
Referring to fig. 1, a novel single screw extruder for a terylene production line comprises a base 1 and a single screw extruder body arranged on the base 1. The single-screw extruder body comprises a control box 3, an extruding mechanism and an ultrasonic mechanism.
Extrusion mechanism includes casing, charging barrel 2, screw rod 10, extrudes head 7 and heating mechanism 8, casing one end is connected with control box 3, and the other end is connected with extruding head 7, heating mechanism 8 establishes on the casing, screw rod 10 establishes in the casing, and with power motor 13 in the control box 3 connects. The charging barrel 2 is fixed on the shell, and a discharge hole 21 of the charging barrel is communicated with the inner cavity of the shell.
The ultrasonic mechanism comprises an ultrasonic generator 4 and an emitting part 9, the ultrasonic generator 4 is arranged in the control box 3, and the emitting part 9 is fixed on the shell and connected with the ultrasonic generator 4.
Further, in order to facilitate the arrangement of the heating mechanism and the ultrasonic mechanism, the housing may be designed to be a layered structure, which includes the first housing layer 5, the second housing layer 6, and the third housing layer 11 from the outside to the inside. The heating means 8 may be arranged in a cavity between the first housing layer 5 and the second housing layer 6, the emitting portion 9 may be arranged in a cavity between the second housing layer 6 and the third housing layer 11, and the emitting portion 9 may be fixedly connected to the second housing layer 6 or the third housing layer 11.
The emitting part 9 may be an emitting rod and an emitting tube, and when the emitting part 9 is an emitting rod, a plurality of emitting tubes may be uniformly disposed in the cavity between the second case layer 6 and the third case layer 11 to improve the ultrasonic efficiency.
