Anti-blocking plastic particle melting and feeding device in cable processing process

Abstract

The invention discloses an anti-blocking plastic particle melting and feeding device in the cable processing process, and belongs to the technical field of cable processing. The anti-blocking plastic particle melting and feeding device comprises a melting tank, a heating part is installed at the inner bottom of the melting tank, a first heat preservation jacket is installed on the outer side of the melting tank in a sleeving mode, a first heat preservation cavity is formed in the first heat preservation jacket, an exhaust pipe is fixed to the top of the first heat preservation jacket, a first valve is installed on the pipe section of the exhaust pipe, a plurality of supporting rods are fixed to the top of the exhaust pipe, the same hemispherical shell is fixed to the tops of the supporting rods, and the bottom of the heating part extends into the first heat preservation cavity; and by arranging the first heat preservation jacket and a second heat preservation jacket and heating heat conduction oil in the first heat preservation cavity and a second heat preservation cavity through the heating part, the situation that molten plastic on the inner wall face of the melting tank is hardened can be avoided, the problem that a discharging pipe is prone to being blocked due to the fact that the discharging pipe cannot be heated is solved, the melting speed of plastic particles can be increased, and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of cable processing, and in particular relates to an anti-blocking type plastic particle melting feeding device in the cable processing process. Background technique [0002] Cable is a general term for optical cables, cables and other items. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, and power transmission. It is a common and indispensable thing in daily life. Due to the The purpose is to transmit electric energy, so it is necessary to insulate the cable. At present, most cables are insulated by wrapping a plastic layer outside the metal inner core. [0003] In the existing device for melting plastic granules, a part of the plastic granules will enter the inside of the feeding pipe when feeding. The plastic granules in this part will not melt because they cannot be heated. At the same time, because the feeding pipe cannot be heated. ...

Problems solved by technology

[0004] The purpose of the present invention is to provide an anti-blocking type plastic particle melting feeding device in the cable processing process, which solves the problem that some plastic particles will enter the inside of the feeding pipe when the existing device for plastic particle melting is fed. Part of the plastic particles will not melt because they cannot be heated. At the same time, because the feeding tube cannot be heated, the plastic remaining inside the feeding tube will harden after feeding, causing the problem of blocking the feeding tube.

[0006] Adopting the above scheme, by setting the insulation jacket one and the insulation jacket two, and using the heating part to heat the heat transfer oil in the insulation cavity one and the insulation cavity two, it can not only avoid the melting of the molten plastic on the inner wall of the tank, but also solve the problem. It solves the problem that the discharge pipe is prone to blockage because it cannot be heated, and can accelerate the melting speed of plastic particles, which is practical; by setting the exhaust pipe and valve 1, it is convenient to maintain the insulation chamber 1 and the insulation chamber during the process of heat transfer oil entering and exiting. The balance of the internal air pressure, combined with the support rod and the hemispherical shell, can effectively prevent dust from entering the interior of the insulation chamber 1 and insulation chamber 2; by setting the baffle and the gasket, the gravity of the baffle is used to press the gasket tightly At the end of the feed pipe, it can prevent the material in the melting tank from entering the inside of the feed pipe, and will not adversely affect the feeding of the feed pipe
