Description

Technical Field

[0001] The utility model belongs to the technical field of foaming furnaces, and particularly relates to a vertical foaming gas furnace for IXPP films. Background Art

[0002] The technology of plastic foaming has a long origin. The earliest was foam bakelite in the early 1920s, prepared by a method similar to that of manufacturing foam rubber; rigid polyurethane foam and polystyrene foam appeared in the 1930s; polyethylene, polyvinyl chloride, epoxy resin, and phenolic foam appeared in the 1940s; expandable polystyrene foam and flexible polyurethane foam appeared in the 1950s. Basically, all plastics, including thermoplastics and thermosets, can be foamed into foam plastics. Industrial preparation methods include: extrusion foaming, injection foaming, molding foaming, calendering foaming, powder foaming, spraying foaming, and so on.

[0003] Among them, a Chinese patent for a new type of natural gas heating polyolefin vertical foaming furnace, with the application number

[0004] <2022204>43651.8>, includes a furnace body, a preheating pipeline, and a preheating box. The inside of the furnace body is a cavity structure. The preheating pipeline is installed on one surface of the furnace body, the preheating box is installed on the upper surface of the preheating pipeline, a heating fan is installed inside the preheating box, several first ventilation grooves are arranged on the upper surface of the preheating box, a driving shaft is embedded at one end inside the preheating pipeline, a driven shaft is installed at the other end inside the preheating pipeline, conveyor belts are embedded on the circumferential sides of the driving shaft and the driven shaft, the driving shaft and the driven shaft are rotationally matched with the preheating pipeline, a transmission shaft is installed at one end of the driving shaft, and a motor is installed at one end of the transmission shaft.

The internal drive motor 5 of the heating chamber 201 rotates the fan blades 501. With the help of the heating wire 6, the IXPP film foaming material inside the preheating pipe 2 is preheated before entering the furnace body 1. After the IXPP film foaming material enters the furnace body 1, the fan blades 501 rotate through the drive motor 5 inside the heating chamber 3, which can improve the temperature inside the furnace body 1 and make the temperature more uniform. A temperature sensor 9 is installed on the right side inside the furnace body 1. With the help of the heating wire 6 and the temperature sensor 9, it can play an auxiliary heating role, which makes it easier to control the temperature inside the foaming furnace.

[0028] Example 2:

[0029] like Figures 1 to 4As shown, a vertical foaming gas furnace for IXPP film is provided. Ventilation fans 4 are installed on both the front and back of the furnace body 1. The ventilation fans 4 work together to exhaust hot air from inside the furnace body 1, quickly cooling the furnace body 1. Ventilation vents 301 are provided on the outer side of the heating chamber 3. A discharge port 7 is located on the bottom right side of the furnace body 1. Multiple auxiliary positioning rollers 8 are installed at the top of the discharge port 7, the bottom of the preheating pipe 2, and the left side of the furnace body 1 to facilitate the movement and discharge of the IXPP film foaming raw material. 3 is connected to the second connection port 101, and the preheating box 201 is connected to the first connection port 202. The top of the preheating pipe 2 is provided with a mounting base 10, and a hydraulic push rod 11 is provided inside the mounting base 10.

The slidable connection between the two ends of the cutting blade 12 and the preheating pipe 2 makes the cutting process smoother.

[0030] In summary, by using the combined operation of the drive motor, fan blades, and heating wire inside the first connecting port of the preheating box, the IXPP film foaming raw material inside the preheating pipe is preheated before entering the furnace, reducing the energy consumption of gas. The drive motor and fan blades inside the heating box can circulate the temperature inside the furnace, making the temperature more uniform. The heating wire inside the second connecting port and the temperature sensor work together to provide auxiliary heating, which facilitates the temperature control inside the foaming furnace. Ventilation fans are installed on both the front and back of the furnace body. By using the ventilation fans, the hot air inside the furnace body can be discharged, which can quickly cool the furnace body, not only achieving the specified temperature requirements but also rapidly reducing the temperature inside the furnace.
