In the startup process of the sizing machine, an operator needs to press a plurality of corresponding knob switches (for example, a two-stage self-locking knob switch) such as a main press roller 42, a pre-press roller 32, a main immersing roller 41, a pre-immersing roller 31, and a circulating pump of a sizing tank down (in the sizing machine view shown in fig. 1, the knob corresponding to the main press roller 42 is operated to the right), the main immersing roller 41 is pressed to the left (in the sizing machine view shown in fig. 1, the knob corresponding to the main immersing roller 41 is pressed to the left), the pre-press roller 32 is pressed down (in the sizing machine view shown in fig. 1, the knob corresponding to the pre-press roller 32 is pressed to the right), the pre-immersing roller 31 is pressed to the left (in the sizing machine view shown in fig. 1, the knob corresponding to the circulating pump is pressed to the left), and the sizing pump is started (in the sizing machine view shown in fig. 1). The circulation pump sizing may be controlled again depending on the production, waiting a period of time after the pre-dip roll 31 is pressed to the left.

In the shutdown process of the sizing machine, an operator needs to turn off the circulation pump (for example, a second-gear self-locking knob switch in the sizing machine view shown in fig. 1) on a plurality of corresponding knob switches (for example, the main press roller 42, the pre-press roller 32, the main immersing roller 41, the pre-immersing roller 31, the circulation pump, etc.) in the sizing machine view, press the pre-immersing roller 31 to the right side (for example, the pre-immersing roller 31 to the right in the sizing machine view shown in fig. 1), lift the pre-press roller 32 (for example, the pre-press roller 32 to the left in the sizing machine view shown in fig. 1), press the main immersing roller 41 to the right (for example, the main immersing roller 41 to the right in the sizing machine view shown in fig. 1), and lift the main press roller 42 (for example, the main press roller 42 to the left in the sizing machine view shown in fig. 1) to shutdown. After turning off the circulation pump, a period of time may be waited for, for example, letting the shower device flush for 30 seconds, and then performing the operation of pressing the pre-submerged roller 31 to the right.

The number of switches on the sizing machine is numerous, and other interference knobs exist, so that even a skilled operator cannot ensure that the problem can not occur forever, however, once errors occur in the working process of the sizing groove, the working progress can be delayed, the product waste and the quality problem are caused, the production efficiency is reduced, and the production cost is increased.

For the above reasons, the present invention provides a sizing machine on-off monitoring system, applied to a sizing machine, as shown in fig. 1, comprising: a slurry tank 10 for accommodating slurry 20; a pre-press roller assembly 30 and a main press roller assembly 40 sequentially disposed along a yarn transfer direction FA; and both the pre-pressing roller assembly 30 and the main pressing roller assembly 40 are arranged in the stock chest 10; the pre-pressing roller assembly 30 comprises a pre-immersing roller 31 and a pre-pressing roller 32, wherein the pre-immersing roller 31 and the pre-pressing roller 32 are sequentially arranged in the slurry tank 10 along the yarn conveying direction FA; the main press roller assembly 40 includes a main submerged roller 41 and a main press roller 42, and the main submerged roller 41 and the main press roller 42 are sequentially disposed in the stock tank 10 in the yarn conveying direction FA.

The power-on trigger signal refers to a signal that can indicate that a user wants to start the sizing machine, for example, a high-level signal generated by triggering when the user presses a power-on button, a control instruction issued by the user through a computer, and the like. Similarly, the shutdown trigger signal refers to a signal that can indicate that the user wants to shutdown the sizing machine, for example, the shutdown trigger signal may be a low-level signal generated by triggering when the user presses a shutdown button, or may be a control instruction issued by a worker through a computer communicatively connected to the controller 1. The controller 1 may be a programmable logic controller 1 or the like.

Specifically, after the slurry is injected into the slurry tank, the yarn SX sequentially passes through the pre-immersing roller 31, the pre-pressing roller 32, the main-immersing roller 41 and the main-pressing roller 42 according to the yarn conveying direction FA, during the sizing operation, a worker sends a start-up trigger signal to the controller 1 through a start-up button or a computer, when the controller 1 receives the signal, the controller sequentially controls the main-pressing roller 42 to descend, the main-immersing roller 41 to side pressure in the yarn conveying direction FA, the pre-pressing roller 32 to descend and the pre-immersing roller 31 to side pressure in the yarn conveying direction FA, and when the yarn SX on the production line is sized or otherwise needs to stop controlling the sizing machine, the worker can send a shutdown trigger signal to the controller 1 through a shutdown button or the computer, and when the controller 1 receives the shutdown trigger signal, the worker sequentially controls the pre-immersing roller 31 to side pressure in the opposite direction of the yarn conveying direction FA, the pre-pressing roller 32 to ascend, and the main-pressing roller 41 to side pressure in the opposite direction FA. The on-off control process does not need manual operation, one-key on-off can be realized, the on-off control can be guaranteed according to a preset sequence, the problem of misoperation caused by the difference of manual experience can be avoided, the production efficiency and the production reliability can be guaranteed, and the quality of the yarn SX is guaranteed.

The pre-soaking roller 31, the pre-pressing roller 32, the main soaking roller 41, and the main pressing roller 42 may be sequentially controlled to be opposite to the yarn conveying direction FA, in the pre-shutdown order by controlling the on/off state of each intermediate relay.
