DETAILED DESCRIPTION

[0021] The utility model will be further described below in conjunction with the accompanying drawings.

[0022] like Figure 1As shown, the preferred embodiment of the heating device of the aluminum-plastic cover separator of the utility model comprises a fixing frame 1, a heating mechanism A, an air outlet pipe 7 and a nozzle 8. The fixing frame 1 is mounted on the feeding mechanism of the aluminum-plastic cover separator, the air outlet pipe 7 is fixed on the fixing frame 1, and a plurality of nozzles 8 are evenly mounted on the air outlet pipe 7. The gap between the nozzles 8 is consistent with the gap between the aluminum-plastic cover on the feeding mechanism of the aluminum-plastic cover separator, so that the nozzles 8 correspond to the aluminum-plastic cover one by one, so that each nozzle 8 can heat the aluminum-plastic cover without wasting the heated air. The air inlet pipe 5 is mounted on the heating mechanism A, and the air enters the heating mechanism A through the air inlet pipe 5. The heating mechanism A is mounted on the air outlet pipe 7, and the heating mechanism A is used to heat the air. The air enters the heating mechanism A through the air inlet pipe 5, and the heating mechanism A heats the air. The air heated by the heating mechanism A enters the air outlet pipe 7, and the air outlet pipe 7 is discharged through the nozzle 8 to heat the aluminum-plastic cover.

[0023] The upper end of the air inlet pipe 5 is provided with a retaining ring 51, which is used to limit the length of the air inlet pipe 5 inserted into the heating mechanism A, and can also prevent the air inlet pipe 5 from falling into the heating mechanism A. The air inlet pipe 5 is inserted into the heating barrel 4, and has an air outlet 52 on the air inlet pipe 5. The air outlet 52 is arranged horizontally, so that the air coming out of the air outlet 52 can prolong the retention time in the heating mechanism A to ensure that the temperature of the heated air meets the requirements. In other embodiments, the air outlet 52 can also be tilted upward to further extend the retention time.

[0024] The heating mechanism A includes an insulated barrel 2, a heater 3, a heating barrel 4, an air inlet pipe 5 and a support frame 6. The heater 3 is in the shape of a hollow cylinder and is used for generating heat. The heating barrel 4 is fixed to the middle of the heater 3 by welding or other fixing methods, so that the heater 3 can heat the heating barrel 4. The bottom of the heating barrel 4 is connected and fixed to the air outlet pipe 7, so that the heated air is introduced into the air outlet pipe 7. The insulated barrel 2 is installed on the heater 3, and the insulated barrel 2 is used to prevent the heater 3 from being exposed to the outside, which can reduce the damage caused by accidentally touching the heating mechanism A; the insulated barrel 2 is filled with an insulating filler 21 in the insulated barrel 2, and the insulating filler 21 can be made of items with low thermal conductivity such as insulating cotton, which further reduces the temperature of the outer wall of the insulated barrel 2. The upper end of the support frame 6 is fixed to the insulated barrel 2, and the lower end of the support frame 6 is connected to the air outlet pipe 7, so that the heating mechanism A can be supported on the air outlet pipe 7 to strengthen the support for the heating mechanism A. In order to slow down the flow speed of the air, the heating barrel 4 may be filled with a non-flammable filler 41 , such as asbestos, etc. The heater 3 heats the barrel 4 , and the air is heated in the heating barrel 4 and then enters the air outlet pipe 7 .

[0025] The support frame 6 is L-shaped, and a strip-shaped fixing hole (not shown) is provided at the bottom of the support frame 6. A fixing protrusion 71 is provided on the air outlet pipe 7. A screw passes through the strip-shaped fixing hole and is screwed on the fixing protrusion 71, thereby fixing the support on the air outlet pipe 7.

[0026] The air outlet pipe 7 is provided with a lower joint 72 , and the bottom of the heating barrel 4 is provided with an upper joint 42 , and the upper joint 42 is connected to the lower joint 72 .

[0027] The heater 3 includes a shell 31 and an electric heating wire 32. The electric heating wire 32 is arranged in the shell 31. The electric heating wire 32 heats the shell 31. The shell 31 transfers heat to the heating barrel 4, so that the heating barrel 4 transfers heat to the air.

[0028] The air enters from the air inlet pipe 5, and then enters the heating barrel 4 through the air outlet hole 52. The heater 3 heats the heating barrel 4. The air enters the air outlet pipe 7 after being heated in the heating barrel 4. The air is ejected from the air outlet pipe 7, thereby heating the aluminum-plastic cover on the feeding mechanism of the aluminum-plastic cover separator. The air does not pass through the heating barrel 4 directly, which prolongs the time the air stays in the heating barrel 4, ensuring that the air can be heated to the required temperature. At the same time, the air is isolated from the heater 3 by the heating barrel 4 and does not come into direct contact with the heater 3, so the heater 3 is not easily damaged.

[0029] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
