referring to fig. 1 to 5, a coater oven for PET protection film disclosed in this embodiment includes a box 1 and a hot air assembly.

The box 1 is a cuboid, and the box 1 and two vertical surfaces which are vertical to the length direction and opposite to the length direction are respectively provided with a feed inlet 2 and a discharge outlet 3 which are opposite to each other. When the device is used, the protective film enters the box body 1 from the feeding hole 2 to be dried, and then the box body 1 is moved out from the discharging hole 3.

The hot air assembly comprises a hot air nozzle 4, an air supply pipe 5 and a hot air blower (not shown in the figure). The hot air nozzle 4 is arranged on the inner top surface of the box body 1, the output end of the hot air nozzle faces downwards, one end of the blast pipe 5 is connected with the hot air nozzle 4, and the other end of the blast pipe extends out of the box body 1 and is connected with an air outlet of the air heater. The hot air components are provided with a plurality of groups (five groups are shown in the figure), and hot air spray heads 4 of the hot air components are uniformly distributed along the length direction of the top surface of the box body 1 at intervals. When the air heater starts, the hot air nozzle 4 blows hot air into the box body 1, so that the protective film in the box body 1 can be dried.

Be provided with the backing roll 6 with the same quantity of hot-blast subassembly in the box 1, a plurality of backing rolls 6 distribute between feed inlet 2 and discharge gate 3 and be located same height, and a plurality of backing rolls 6 are used for supporting the protection film that enters into in the box 1.

The same position of each supporting roller 6 is provided with a guide mechanism, the guide mechanism comprises two guide rings 7 which are sleeved on the supporting rollers 6, and an interval for the protective film to pass through is arranged between the two guide rings 7 on each supporting roller 6.

And a locking assembly is arranged on the guide ring 7 and comprises a connecting rod 8, a locking ring 9 and a locking piece 10. The connecting rods 8 are horizontally arranged on the guide rings 7, and the connecting rods 8 on the two guide rings 7 on each supporting roller 6 are respectively welded on vertical surfaces of the two guide rings 7 which are deviated from each other. The locking ring 9 includes a first half ring 91, a second half ring 92, and a connecting shaft 93. One end of the first half ring 91 is rotatably connected with one end of the second half ring 92 through a connecting shaft 93, one end of the connecting shaft 93 is coaxially welded with the connecting rod 8, and the first half ring 91 and the second half ring 92 are jointly encircled on the supporting roller 6. The first half ring 91 is integrally formed with a first engaging lug 11 at an end away from the connecting shaft 93, and the second half ring 92 is integrally formed with a second engaging lug 12 at an end away from the connecting shaft 93. The locking piece 10 is arranged on the first connecting lug 11 and the second connecting lug 12, and the locking piece 10 is used for locking and fixing the first connecting lug 11 and the second connecting lug 12.

Retaining member 10 is locking screw and lock nut, and locking screw runs through engaging lug 11 and two 12 and locking screw's of engaging lug head end and the laminating of engaging lug 11, and lock nut cup joints on locking screw and with the laminating of two 12 of engaging lugs, and lock nut cooperation locking screw's head end is with engaging lug 11 and two 12 tight fixings of clamping of engaging lug.

With the above arrangement, when the locking assembly is locked, the position of the guide ring 7 on the support roller 6 is fixed, and when the locking assembly is unlocked, the guide ring 7 can move along the length direction of the support roller 6. To improve the locking effect of the locking assembly on the guide ring 7: the first half ring 91 and the second half ring 92 are located in the same plane; the opposite surfaces of the first connecting lug 11 and the second connecting lug 12 are attached; the surface of the first half ring 91 in contact with the support roller 6 and the surface of the second half ring 92 in contact with the support roller 6 are both provided with a frosted layer.
