Technical Field

The utility model belongs to the technical field of lithium-ion battery pole piece processing apparatus, especially, relate to an auxiliary stop gear of lithium-ion battery pole piece heating device access door.

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. Because the impact force that releases a large amount of heat energy production can make the door plant open clockwise a little among the current heating device, leads to thermal a large amount of emissions, consequently need design an auxiliary limit mechanism for door plant, avoids the problem that the door plant opened because of the release of heat energy effectively.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that the impact force that produces because a large amount of heat energy of release can make the door plant open clockwise slightly among the current heating device, leads to thermal a large amount of emissions, in order to improve its weak point, the utility model provides a lithium battery pole piece heating device access door's supplementary stop gear.

In order to achieve the purpose, the utility model is realized by the following technical proposal:

the utility model provides an auxiliary limiting mechanism of lithium battery pole piece heating device access door, the access door is including the fixed plate of being connected with the heating device outside, the fixed plate lower extreme articulates there is the door plant, and the heating device outside that is located the door plant below is provided with articulated seat, be connected through air spring between articulated seat and the door plant, be provided with horizontally U template on the heating device outer wall that is located articulated seat top, the both ears board section free end and the heating device outer wall connection of U template are provided with the diaphragm on the heating device outer wall that is located U template below, set up horizontally waist type groove on the diaphragm, and it has the cross axle to be close to alternate between the both ears board section of U template interlude, has hung the ring on the cross axle that is located between the both ears board section of U template, the ring lower extreme is located waist type inslot and sets up, the door plant side is provided with spacing post.

As preferred scheme, the heating device outer wall is connected with the riser through connecting bolt, the riser upper end is connected with U template otic placode section both ends, and the riser lower extreme is connected with the diaphragm free end, riser, U template and the integrative setting of diaphragm.

As a preferred scheme, a high-temperature-resistant sleeve body is sleeved outside the circular ring.

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 contradicted and is just being on the door plant upper surface.

Preferably, the upper part of the fixing plate is connected with the outer surface of the free end of the door panel through a chain.

The utility model discloses the during operation, when the door plant anticlockwise closes, the spacing post in the door plant outside rotates to between U template and the diaphragm, spacing post is to inboard extrusion ring, make the ring internal surface conflict clockwise rotation on the cross axle, thereby when making the door plant close, spacing hub position is in the inboard setting of ring, when the door plant closes the trend that the back produced clockwise opening because of the heat energy of the inside release of heating device, the cross axle is contradicted on the ring surface, and the ring outer end is contradicted respectively on the interior terminal surface of U template interlude and waist type groove, can't rotate, thereby reached the supplementary spacing effect to the door plant.

Compared with the prior art, the beneficial effects of the utility model are that: the device sets up through the cooperation of spacing axle with the ring, can prevent that the door plant from closing the back because of the inside heat energy that releases of heating device to make the door plant open the problem that leads to the heat to leak slightly, improved the security of whole device, the device is applicable to in the industrial production, has very strong practicality.
