Description

Technical Field

[0001] The utility model relates to a wire installation device for a spinning screw extruder, belonging to the technical field of spinning screw extruders. Background Art

[0002] The spinning screw extruder is a key component of textile equipment, mainly used to heat, melt, mix and extrude polyester raw materials to form a molten body. The screw extruder consists of a screw, a barrel and a heating tile. The heating tile is connected to the power cord through a terminal. When the screw rotates, the raw material is gradually heated in the barrel and undergoes plasticization and homogenization treatment to ensure the uniformity and stability of the melt. However, the applicant found in actual production that the spinning screw extruder is prone to shutdown due to line damage after running at high temperature for a period of time. After disassembling and analyzing the machine, it was found that the power cord connected to the heating tile is easily damaged. Currently, this problem still occurs after the equipment has been running for a period of time after replacing the wire. It is necessary to conduct research and improvement on this. Utility Model Content

[0003] Based on the above, the utility model provides a wire installation device for a spinning screw extruder to overcome the deficiencies of the prior art.

[0004] The technical solution of the utility model is: a wire installation device for a spinning screw extruder, comprising:

[0005] An extrusion assembly includes a screw, a barrel sleeved on the screw, and a heating tile sleeved on the barrel, wherein the heating tile is provided with a terminal;

[0006] The installation component includes a wire tube installed outside the heating tile and a power cord installed in the wire tube. One end of the power cord is connected to the terminal, and the other end extends outward after passing through the wire tube. The wire tube is an insulated steel tube.

[0007] In one example, the wire tube is fixed to the barrel in an annular direction, and a mounting hole is provided on the wire tube at a position corresponding to the terminal, so that the terminal extends into the wire tube.

[0008] In one example, an inlet and an outlet are respectively provided at both sides of the lower portion of the conduit, a partition is provided between the inlet and the outlet, and the power line enters the conduit through the inlet or the outlet.

[0009] In one example, the inlet is connected to the cold source device through a cold air pipe, a valve is provided on the cold air pipe, the valve is electrically connected to a controller, and a timer is provided on the controller.

[0010] In one example, the power cord is connected to the terminal through a stainless steel high-temperature resistant wire nose.

[0011] In one example, the power wire is a nickel wire.

[0012] The beneficial effects of this utility model are as follows: by enclosing the power cord within the insulated steel tube, compared to the previous method of placing the power cord tightly against the heating tile, the heat is insulated to a certain extent, preventing the heating tile from affecting the power cord, thereby protecting the power cord from damage. Furthermore, by securing the conduit in a circular pattern to the barrel and providing an inlet, outlet, and cold air duct, cold air can be introduced into the conduit, thereby cooling the power cord and further extending its service life.

[0018] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] See also Figure 1 and Figure 2 , this embodiment provides a wire installation device for a spinning screw extruder, including an extrusion component and an installation component.

[0020] The extrusion assembly includes a screw 11, a barrel 12 sleeved outside the screw 11, and a heating tile 13 sleeved outside the barrel 12. The heating tile 13 is provided with a terminal 14, through which power is introduced, and the heating tile 13 realizes the heating function of the barrel 12. The installation assembly includes a wire tube 21 installed outside the heating tile 13 and a power cord 22 installed inside the wire tube 21. One end of the power cord 22 is connected to the terminal 14, and the other end passes through the wire tube 21 and extends outward. The wire tube 21 is an insulated steel tube.

[0021] By sheathing the power cord 22 in the insulating steel pipe, compared with the original power cord 22 being tightly attached to the heating tile 13, heat can be isolated to a certain extent, avoiding the influence of the heating tile 13 on the power cord 22, thereby protecting the power cord 22.

[0022] To improve thermal insulation, a conduit 21 is annularly fixed to the barrel 12. Mounting holes are provided on the conduit 21 corresponding to the terminals 14, allowing the terminals 14 to extend into the conduit 21. This allows the power cord 22 and the terminals 14 to be located within the conduit 21, better protecting the connection points from damage due to high temperatures. The conduit 21 can be mounted outside the heating tile 13.

[0023] In order to further protect the power cord 22, an inlet 23 and an outlet 24 are respectively provided on both sides of the lower part of the wire pipe 21. A partition 26 is installed between the inlet 23 and the outlet 24 to separate the two sides. The power cord 22 passes into the wire pipe 21 through the inlet 23. The inlet 23 is connected to the cold source equipment through the cold air pipe. The cold source equipment can be a cold air duct 27 in the workshop. A valve 28 is provided on the cold air duct. The valve 28 is electrically connected to the controller. The controller is provided with a timer, which can set the time interval for opening the valve 28. When the valve 28 is opened, cold air enters the wire pipe 21 from the cold air duct 27, thereby achieving cooling treatment of the power cord 22.

[0024] In order to increase the service life, the power cord 22 is connected to the terminal 14 through a stainless steel high-temperature resistant wire nose 25, which has a longer service life than a wire nose that is not resistant to high temperatures.

[0025] In order to increase the service life, the power line 22 is a nickel wire, which can withstand a temperature of 800° C. compared to traditional copper wires, thereby extending the service life.

[0026] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
