After applying glue on the polymer coil substrate and laminating it with the reinforcing fabric, it still needs to be dried to form.

[0003] Publication No.: CN215002732U includes a drying housing. A right hot air blower is fixedly installed at the top of the drying housing. The air outlet of the hot air blower is communicated with a conveying hose. The bottom of the conveying hose is communicated with a plurality of spray heads. The same rotating shaft is rotatably installed on the inner walls of the left and right sides of the drying housing. Both sides of the top of the conveying hose are fixedly installed with connecting plates. The inner sides of the connecting plates are fixedly connected with the outer sides of the rotating shaft. One end of the rotating shaft extends to the outside of the drying housing and is fixedly installed with a first gear. The structure of the utility model is reasonably designed. The work of the hot air blower enables hot air to be ejected from the spray heads, so as to dry the coil body. The swinging work of the spray heads can improve the drying efficiency and has high reliability.

[0004] The applicant finds that there are some deficiencies in use: during the winding process, since the coil is not flattened and limited, the coil may be wrinkled and uneven after being dried, and the coil may shift during winding, affecting the winding effect. At the same time, it is not convenient to replace the winding roller after it is full.

[0005] Therefore, the utility model designs a drying device for polymer coils to solve the problems existing in the prior art. Summary of the Utility Model

[0011] Preferably, a guiding strip is installed at one end of the driving shaft. A guiding groove slidably connected with the guiding strip is opened in the winding roller. Only when the guiding strip and the guiding groove are aligned can the driving shaft be inserted into the slot. After insertion, the positions of the plug rod and the jack are parallel, which is convenient for the staff to limit the driving shaft and the slot.

[0012] Preferably, an operation groove is opened on the driving shaft. One side of the lead screw penetrates through the operation groove and is installed with a knob, which is convenient for the staff to rotate the lead screw.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the setting of the limiting and flattening mechanism of the present utility model, after the coil is dried, it is conveyed between the two pressing rollers, and the two pressing rollers extrude the coil, which can improve the flatness of the coil. And the limiting rollers at both ends of the coil can limit the conveyed coil to prevent the coil from shifting.

[0015] 2. With the provision of the replacement mechanism in the present utility model, when the winding roller is fully wound, turn the lead screw to make the wire block slide. Through the connecting rod, make the insertion rod leave the jack, and the limit between the driving shaft and the slot can be cancelled. The staff pulls the winding roller towards one end to make the slot leave the driving shaft, and then it can be taken out upwards to replace the winding roller. Replace it with a new winding roller, place one end of the winding roller in the arc-shaped groove, then move the winding roller to connect the slot at the other end of the winding roller with the driving shaft. Then turn the lead screw in the reverse direction to make the insertion rod insert into the jack to fix the winding roller. The operation is convenient and it is easy to replace the winding roller.
