Description

Technical Field

[0001] The utility model relates to the technical field of extrusion, in particular to a heating melting cavity for extrusion. Background Art

[0002] Extrusion generally refers to extrusion, which is also called extrusion molding or extrusion in plastic processing, and extrusion in rubber processing. It refers to a processing method in which the material passes through the action between the extruder barrel and the screw, is heated and plasticized, and is pushed forward by the screw, and continuously passes through the head to form various cross-section products or semi-finished products. In order to improve the heating and melting efficiency of plastics, a special heating melt chamber is required to heat and melt the plastic, and then convey it for extrusion operation.

[0003] The existing heating melt chamber for extrusion has the following disadvantages: 1. After melting, the material cannot be automatically discharged when the internal air pressure reaches the set value, and the air pressure is used to prevent material blockage and improve the discharge efficiency. To this end, we propose a heating melt chamber for extrusion. Summary of the invention

[0004] The main purpose of the utility model is to provide a heating melting cavity for extrusion, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A heating melt chamber for extrusion, comprising a hot melt chamber, an outer sheath shell, a sealing card cover and a control box, wherein a sealing card cover is engaged with the top of the hot melt chamber and an electric heater is installed on the top of the sealing card cover by bolts, a pressure sensor is installed on one side of the top of the hot melt chamber through a mounting hole, an outer sheath shell is sleeved on the outside of the hot melt chamber and a control box is installed on one end of the outer sheath shell by screws, a single-chip microcomputer controller is installed in the control box by screws, a UPS power supply is installed on the lower end of the single-chip microcomputer controller by screws, and an output pipe is connected to the bottom output port of the hot melt chamber and a solenoid valve is provided on the output pipe.

[0007] Furthermore, the output and input ends of the single-chip microcomputer controller are electrically connected to the input end of the solenoid valve and the output end of the pressure sensor through wires, and the pressure value in the hot melt cavity is detected by the pressure sensor and transmitted to the single-chip microcomputer controller for analysis and processing. When it exceeds the set value, the single-chip microcomputer controller automatically controls the solenoid valve to open and automatically discharge the material.

[0008] Furthermore, the heating tube of the electric heater is located in the hot melt cavity.

[0009] Furthermore, the detection end of the pressure sensor is located in the hot melt cavity, and the sealing card cover is connected to the top of the hot melt cavity through threads, so that the sealing box cover is used to achieve the effect of installing and sealing the control box.

[0010] Furthermore, a sealing box cover is installed on one side of the control box through positioning screws.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model discloses a heating melt chamber for extrusion molding. The sealing card cover is opened to add plastic granule raw materials into the hot melt chamber. Since the heating tube is directly inserted into the plastic granule raw materials and the hot melt chamber is designed in a long cylindrical shape, the heating rate of the hot melt chamber is greatly improved, so that the plastic granule raw materials are melted quickly. When the melting is completed, the hot gas expands and increases the air pressure in the hot melt chamber.

[0013] 2. The utility model is a heating melt cavity for extrusion molding. The pressure value in the hot melt cavity is detected by a pressure sensor and transmitted to the single-chip controller for analysis and processing. When the pressure exceeds the set value, the single-chip controller automatically controls the solenoid valve to open and automatically discharge the material, and increases the discharge rate with the help of air pressure to avoid insufficient injection temperature caused by slow discharge, and also has the effect of preventing material blockage.

[0027] It should be noted that the utility model is a heating melt cavity for extrusion.
