Background
In the current lithium ion power battery production industry, after the coiled pole piece is coated with the electrode slurry, the pole piece is usually heated in the following manner before further shaping: 1. the heating resistor directly heats and dries the circulating air, and then the pole piece is heated by the circulating air; 2. heating heat conducting oil, heating dry circulating air by the heat conducting oil, and heating the pole piece by the dry circulating air; 3. the drying circulating air is heated by high-temperature steam, and then the pole piece is heated by the drying circulating air. These heating methods are all heating a large amount of circulating air, and then heating the pole piece by the hot circulating air. This heating process releases a large amount of heat energy into the space environment by heat radiation, making the overall energy efficiency less than 40%. This results in a great waste of energy and also in a great burden on the environment due to the large amount of heat discharged. The access door rotates the switching among the current heating device, and there is the problem of not tightly closing the access door after closing, because the inside heat energy that is releasing always of heating device for the swing that the access door is slight always collides with the heating device outer wall, has certain limitation.

In order to achieve the purpose, the utility model is realized by the following technical scheme:
a limiting mechanism of an access door of a heating device of a lithium battery pole piece comprises a fixed plate connected with the outer side of the heating device, a door plate is hinged to the lower end of the fixed plate, the upper portion of the fixed plate is connected with the outer surface of the free end of the door plate through a chain, a hinged seat is arranged on the outer side of the heating device below the door plate, the hinged seat is connected with the middle portion of the door plate through an air spring, one end of a cylinder barrel of the air spring is hinged to the middle portion of the door plate, the free end of a piston rod of the air spring with an inclined downward direction is hinged to the outer side of the hinged seat, a rotating piece with an L-shaped section is hinged to the inner side of the hinged seat, two threaded connecting holes are formed in the hinged seat, the free end of a vertical section of the rotating piece is connected with any threaded connecting hole through a locking bolt, an inclined limiting section extends from the side surface of the vertical section of the rotating piece, and a limiting supporting piece is arranged on the upper surface of the limiting section, when the door panel rotates to the vertical state, the top of the limiting support part is abutted against the outer surface of the door panel.
According to the preferable scheme, the limiting support piece is a limiting bolt, the free end of the limiting bolt penetrates through the limiting section, limiting nuts are screwed on the limiting bolts on the two sides of the limiting section, and when the door plate rotates to be in a vertical state, the head of the limiting bolt abuts against the outer surface of the door plate.
As preferred scheme, be located the fixed plate side of door plant top and be provided with spacing abutting contact, when the door plant was in the horizontality, vertical decurrent spacing abutting contact was supported on the door plant upper surface.
As a preferred scheme, the surface of the limiting abutting head is sleeved with an elastic rubber pad.
Preferably, the upper part of the fixing plate and the outer surface of the free end of the door panel are both provided with hanging rings, and two ends of the chain are respectively connected with the corresponding hanging rings.
When the door plate rotates to a vertical state, the operator pushes the horizontal section of the rotating part to enable the top of the limiting supporting piece on the limiting section to abut against the outer surface of the door plate so as to fix the door plate, and the limiting supporting piece adopts the limiting bolt so as to adjust the degree of the limiting bolt abutting against the door plate.
Compared with the prior art, the utility model has the beneficial effects that: the device has avoided the door plant to close the back effectively, because of heating device when releasing a large amount of heat energy to the outside, leads to the slight swing that the door plant made a round trip to incessantly collide with the heating device outer wall, improved the life of access door, improved the security of whole device simultaneously, the device is applicable to in the industrial production, has very strong practicality.
