Described tenslator comprises the first dancer 9, first carry-over pinch rolls 10 be located between described discharging roll 2 and described first dispense tip 3, be located between described baking oven 5 and described second dispense tip 4 for regulating the first Deviation rectifier 11 of base material both ends of the surface, be located at described baking oven 5 and described rewinding for the first tension pick-up 12, second carry-over pinch rolls 18 and comprising measuring substrate tension and roll up the second Deviation rectifier 13, second tension pick-up 14, the 3rd carry-over pinch rolls 15 and the second dancer 16 between 6.
Being provided with multiple guide roller 17 for leading to base material in described baking oven 5, being provided with multiple for the heater of base material drying in described baking oven 5 bottom drawer, as shown in Figure 1.
Described baking oven 5 is divided into three sections, three sections of baking ovens 5 are arranged on isolation ward 19, avoid the environment temperature of the temperatures involved constant temperature workshop because of baking oven 5, described baking oven 5 comprise baking oven 501 and be located at below described upper baking oven 501 lower baking oven 502, described upper baking oven 501 side plate is provided with the upper cylinder 7 for opening described upper baking oven 501, described lower baking oven 502 side plate is provided with the lower cylinder 20 for opening described lower baking oven 502, as shown in Figure 4 and Figure 5.
Described frame 8 is also respectively equipped with the drive motors that described first dancer 9, first carry-over pinch rolls 10, first Deviation rectifier 11, first tension pick-up 12, second carry-over pinch rolls 18, second Deviation rectifier 13, second tension pick-up 14 of multiple driving, the 3rd carry-over pinch rolls 15 and the second dancer 16 rotate.
Adopt above-mentioned double spread all-in-one to carry out the method be coated with, comprise following process:
A1, blowing: rotated by discharging roll 2 and base material 1 is pulled out from discharging roll 2;
A2, front coating: base material 1 is coated with by front at the first dispense tip 3 place through the first dancer 9, first carry-over pinch rolls 10;
A3, front are dry: entered described baking oven 5 by the base material 1 that front is coated with and dried, and are specially to enter lower baking oven 502 and dried;
A4, reverse side are coated with: by the base material 1 of drying from described baking oven 5 pass through the first Deviation rectifier 11 and the first tension pick-up 12 applied at the second dispense tip 4 reverse side;
A5, reverse side are dry: entered described baking oven 5 once again by the base material 1 that reverse side is coated with and dried, and are specially to enter baking oven 501 and dried;
A6, rewinding: successively received by rewinding volume 6 after the second Deviation rectifier 13, second tension pick-up 14, the 3rd carry-over pinch rolls 15 and the second dancer 16 by the base material 1 of drying.
In the utility model base material 1 be lithium battery diaphragm; the effect of coating machine of the present utility model coats pottery for this lithium battery diaphragm is two-sided; this base material 1 is walked film and is controlled by four sections of tension force altogether on coating machine, guarantees that base material 1 can be stablized smooth by each parts.
Discharging roll 2, first dancer 9 and the first carry-over pinch rolls 10 control the first paragraph tension force of base material, and wherein the first dancer 9 is responsible for detecting and feedback;
First carry-over pinch rolls 10, first dispense tip 3, first Deviation rectifier 11, first tension pick-up 12 and the second carry-over pinch rolls 18 control the second segment tension force of base material, are wherein detected by the first tension pick-up 12 and are fed back;
Second carry-over pinch rolls 18, second dispense tip 4, second Deviation rectifier 13, second tension pick-up 14 and the 3rd carry-over pinch rolls 15 control the 3rd section of tension force of base material, are wherein detected by the second tension pick-up 14 and are fed back;
3rd carry-over pinch rolls 15, second dancer 16 and rewinding volume 6 control the 4th section of tension force of base material, are wherein detected by the second dancer 16 and are fed back;
By detecting and feeding back the tension force on base material 1, the skew of base material 1 on roller of can rectifying a deviation, makes base material 1 both sides concordant and carry out rolling on same vertical plane, ensures that base material 1 both ends of the surface on the rewinding volume 6 after rolling are concordant.
Embodiment described in the utility model is only the description carried out preferred embodiment of the present utility model; not utility model design and scope are limited; under the prerequisite not departing from the utility model design philosophy; the various modification that in this area, engineers and technicians make the technical solution of the utility model and improvement, all should fall into protection domain of the present utility model.
