Abstract

[0002] Honeycomb paper is a commonly used material nowadays. Before it can be used, it usually needs to be stretched by a honeycomb paper stretching machine to form a honeycomb hollow shape before it can be used.
[0003] A common unwinding method of the automatic unwinding structure is to clamp one end of the honeycomb paper roll and drag it to unwind. This unwinding method will generate a large pulling force on the honeycomb paper during the unwinding process, causing it to be stretched into a honeycomb hollow in advance, and then be squeezed and fail when passing through the clamping position. This phenomenon will greatly affect the use of the honeycomb paper roll.
[0004] Another common unwinding method of the automatic unwinding structure is to drive the honeycomb paper roll to rotate for unwinding. In this unwinding method, the unwinding speed will change regularly during the consumption process of the honeycomb paper roll. This change is affected by multiple factors such as the thickness of the honeycomb paper and the rotation speed of the honeycomb paper roll. The change in the unwinding speed of the honeycomb paper roll will cause the honeycomb paper to accumulate or pull in the automatic unwinding structure. Utility Model Content

[0034] In some embodiments, in combination Figure 1 As shown, the external control center controls the power shaft 1 to rotate at a fixed speed, and the external control center controls the rotation speed of the output component 3 to change regularly. In this control method, the output speed of the automatic unwinding structure changes in a certain trend, but the rotation of the rotating shaft is more stable, and the external control center has a definite value for the speed control of the output component 3, which makes the control process easier to implement.
[0035] In some embodiments, in combination Figure 1 As shown, the external control center controls the output component 3 to rotate at a fixed speed, and the external control center controls the rotation speed of the power shaft 1 to change regularly. In this control method, the output speed of the automatic unwinding structure is more stable, and constant speed output can be achieved, but the control process is more difficult.
[0036] In some embodiments, in combination Figure 1 As shown, the automatic unwinding structure also includes a support frame 4, the support frame 4 is rotatably connected to the power shaft 1, the support frame 4 is fixedly connected to the output component 3, and the entire automatic unwinding structure is assembled on the support frame 4, so that the entire automatic unwinding structure forms a whole and is more convenient to move.
[0037] In some embodiments, in combination Figure 1 As shown, the support frame 4 is further provided with a U-shaped mounting groove 41, and the power shaft 1 is rotatably assembled in the U-shaped mounting groove 41, which greatly simplifies the assembly process of the power shaft 1 and makes the replacement of the honeycomb paper roll faster.

[0043] Working process: the power shaft 1 starts to rotate under the drive of the first motor 5. At this time, the driven speed measuring pressure shaft 2 is pressed against the honeycomb paper roll and rotates together with the honeycomb paper roll under the action of friction. While pressing the honeycomb paper roll to avoid idling, the speed sensor 21 will collect the speed data of the driven speed measuring pressure shaft 2 and return it to the external control center; at this time, the speed of the first motor 5 is fixed, that is, the speed of the power shaft 1 is fixed. Since the surface speed of the dynamic speed measuring pressure shaft 2 is the same as the real-time honeycomb paper unrolling speed, the speed data collected in real time by the speed sensor 21 can reflect the real-time unrolling speed of the honeycomb paper. After the speed sensor 21 transmits the real-time data to the external control center, the external control center combines the data to adjust the working speed of the output component 3 in real time to ensure that the surface speed of the output shaft 31 is the same as the surface speed of the driven speed measuring pressure shaft 2.
[0044] In some embodiments, the speed of the second motor 6 is fixed, that is, the speed of the output shaft 31 is fixed. At this time, the external control center combines the speed data collected in real time by the speed sensor 21 to adjust the speed of the power shaft 1 in real time to ensure that the surface speed of the output shaft 31 is the same as the surface speed of the driven speed measuring shaft 2.
