[0002] According to the purpose, protective films can be divided into digital product protective films, car protective films, household protective films, food preservation protective films, etc. With the popularity of digital products such as mobile phones in China, protective films have gradually become a general term for screen protective films, and their functions in the field of screen protective films are also varied. The basic production process of existing protective films includes blow molding, casting, calendering, aging and slitting. In related technologies, the aging process of protective films is usually carried out in a aging chamber. The protective film is rolled up on the barrel to form a roll, and then multiple rolls are placed in the aging chamber in order. The top of the aging chamber is connected to a hot ventilation duct, which transports hot air downward into the aging chamber to mature the rolls in the aging chamber.

[0003] After searching (application number: 202121418609.2), it can be learned that a hot air reversing mechanism for a maturation chamber includes a wind shield and a fixing assembly; the wind shield is horizontally arranged, and the wind shield is located at the mouth of the hot ventilation duct and directly below it and above the coil; the fixing assembly includes a plurality of hangers and a plurality of fixing nuts corresponding to the hangers one by one, and the plurality of hangers are vertically fixed to the top of the wind shield, and the top of the hanger movably passes through the top of the maturation chamber, and the end of the hanger passing through the top of the maturation chamber is provided with a threaded section, and the fixing nut is threadedly matched with the end of the hanger passing through the top of the maturation chamber, and the bottom of the fixing nut is abutted against the top of the maturation chamber.

[0004] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: although the hot air reversing mechanism for the maturation chamber is detachably assembled through multiple sets of bolts and accessories, which meets the needs of later replacement, this type of limiting combination is more troublesome to install, time-consuming and labor-intensive, and urgently needs to be improved. Therefore, we propose a hot air reversing mechanism for the maturation chamber. Utility Model Content

A limiting groove 53 is provided on the upper side of the rectangular groove 52, and a limiting rod 54 is positioned in the limiting groove 53. Reinforcing ribs are fixedly installed at the corners of the limiting rod 54, and the reinforcing ribs are of a triangular structure. The connection rigidity can be improved by the reinforcing ribs to prevent tearing and rupture. An indicator sign 51 is fixedly installed on the front side of the baffle 5, and a guide pattern is printed on the indicator sign 51. When the operator uses it for the first time, he can know the corresponding operation method according to the guide pattern, which is convenient for correct and smooth disassembly and assembly; a rectangular block 43 is fixedly installed on the bottom of the inner side of the support rod 4, and the rectangular block 43 is positioned in the rectangular groove 52; a flange 41 is fixedly installed in the middle of the support rod 4, and a sleeve 42 is provided on the lower side of the support rod 4 near the flange 41; an insertion rod 21 is fixedly installed at the bottom of the cross bar 2, and the insertion rod 21 is positioned in the rod groove 12.

[0026] In this technical solution, the rectangular groove 52, the insertion rod 21 and the rod groove 12 and other components can be used in combination. During the use of the hot air reversing mechanism for the maturing chamber, each time the reversing mechanism is assembled, the rectangular block 43 can be shallowly inserted into the rectangular groove 52, and the sleeve 42 is held and moved upward to allow the support rod 4 to pass through the opening 11, and then force is applied to squeeze the support rod 4 so that the rectangular block 43 is completely inserted into the rectangular groove 52. At this time, the insertion rod 21 is aligned with the rod groove 12, and the support rod 4 is slowly lowered.

The rod groove 12 and the insertion rod 21 and the rectangular block 43 and the rectangular groove 52 are locked, and the baffle 5 can be realized. The installation can be completed by reverse operation. Compared with the existing multi-group bolt structure positioning method, the disassembly and assembly process is simplified and it is easy to replace later. By providing the slide groove 45 and the limit rod 54, after the insertion rod 21 is aligned with the rod groove 12, the sleeve 42 is loosened, and the limit rod 54 then falls and is stuck in the limit groove 53 of the baffle 5, which can improve the stability of the assembled reversing mechanism.
