As shown in fig. 2, the prepressing roll 3, the sizing roll 4 and the pressure measuring roll 5 are driving rolls, the prepressing roll 3, the sizing roll 4 and the pressure measuring roll 5 are respectively and rotatably connected to the stock tank 6, a first motor 15 corresponding to the prepressing roll 3, a second motor 16 corresponding to the sizing roll 4 and a third motor 17 corresponding to the pressure measuring roll 5 are fixedly connected to the outer wall of the stock tank 6, the first motor 15 drives the prepressing roll 3 to rotate, the second motor 16 drives the sizing roll 4 to rotate, the third motor 17 drives the pressure measuring roll 5 to rotate, and the first motor 15, the second motor 16 and the third motor 17 are respectively and electrically connected to the controller 13 and respectively controlled by the controller 13.

In this embodiment, the liquid controller 1 is a liquid control roller, the liquid control edge 101 is an axially extending straight line on the roller surface of the liquid control roller, the straight line is closest to the pre-press roller 3, and two ends of the liquid control roller are respectively rotatably connected to a slide block 7.

In practical production, the liquid control device 1 may also be a scraper, as shown in fig. 5, the liquid control edge 101 is a scraper edge, and two ends of the scraper are respectively fixedly connected to a sliding block 7.

The working principle of the invention is as follows: as shown in fig. 1 to 5, the prepressing roll 3, the sizing roll 4 and the pressure measuring roll 5 in the invention are driving rolls, and the rotation center position is kept unchanged in the sizing process, when sizing, the controller 13 respectively controls the rotation speed of the first motor 15, the second motor 16 and the third motor 17, so that the linear speed of the yarn is kept consistent when the yarn passes through the prepressing roll 3, the sizing roll 4 and the pressure measuring roll 5 to eliminate extra drafting, the prepressing roll 3 takes up the size in a triangular area above the contact surface of the prepressing roll 3 and the sizing roll 4 in the rotation process to form a pre-sizing area 18 with a certain amount of size, the yarn 14 is guided into the pre-sizing triangular area 18 through the size inlet roll 2 to perform pre-sizing, then the prepressing roll 3 and the sizing roll 4 perform first extrusion, the yarn is compressed first extrusion and then expanded, the size is taken into the size by the sizing roll 4 in the expansion process to absorb the size into the yarn 14, the yarn 14 absorbs enough size and then is taken out of the size by the sizing roller 4 and enters between the sizing roller 4 and the pressure measuring roller 5 for secondary extrusion, redundant size in the yarn is extruded by the secondary extrusion, and meanwhile, the size is immersed into a deeper layer of the yarn 14, so that the sizing effect is improved.

When the moving speed of the yarn 14 changes due to various reasons, the amount of the sizing carried by the yarn 14 is affected due to the change of the time for soaking the yarn 14 in the sizing solution, for example, when the moving speed of the yarn 14 is reduced, the time for soaking the yarn 14 in the sizing solution is prolonged, when the yarn 14 leaves the sizing solution, the amount of the sizing carried by the yarn is increased, which means that even if the yarn 14 is extruded by the pressure measuring roller 5, the rate of the sizing carried by the yarn is still increased, so that the rate of the sizing carried by the yarn is unstable, at this time, the controller 13 can control the stepping motor 10 to start, the stepping motor 10 drives the screw rod 11 to rotate, the screw rod 11 rotates to drive the slide block 7 to move for a certain distance in the direction close to the pre-pressing roller 3, so that the distance between the liquid controlling edge 101 and the pre-pressing roller 3 is reduced, thereby reducing the sizing solution carried by the pre-pressing roller 3 into the pre-sizing triangular area 18, so that, therefore, the increased slurry carrying amount caused by the prolonged soaking time of the yarn 14 in the slurry is offset, the slurry carrying amount of the yarn 14 when leaving the slurry is always kept consistent, and the stable sizing rate of the yarn is realized under the condition of not changing the squeezing force of the pressure measuring roller 5.

When the moving speed of the yarn 14 is fast, the distance between the liquid control edge 101 and the pre-press roll 3 is increased by reverse operation to increase the amount of the sizing agent in the pre-sizing triangular area 18, thereby increasing the amount of the sizing agent in the pre-sizing of the yarn to offset the amount of the sizing agent reduced by shortening the soaking time of the yarn in the sizing agent, and keeping the amount of the sizing agent unchanged when the yarn leaves the sizing agent.

The controller 13 can monitor the rotating speeds of the first motor 15, the second motor 16 and the third motor 17, and when the rotating speeds of the first motor 15, the second motor 16 and the third motor 17 change, the stepping motor 10 is correspondingly controlled to act to change the size of the sizing liquid in the pre-sizing triangular area 18, so that quick response is realized, and the constant rate of the sizing on the yarn is ensured.
