Problems solved by technology

[0004] (1) The high-speed gypsum board production line needs to replace the protective paper very frequently. Manual paper splicing can no longer meet the high-speed production requirements, and it is easy to cause paper breaks and stop;
[0005] (2) At the same time, during the use of paper, due to the unstable control of the output tension of the paper, there is a certain difference in the transmission speed, and there is a lack of precise control in the switching control of the paper roll, which may easily cause the tension of the paper roll to change. Fracture, large overlapping length of spliced ​​paper and remaining paper volume of paper roll, low production efficiency and high scrap rate of gypsum board
[0006] (3) Due to the existing errors in the consumption calculation of the existing paper rolls, errors are generated when the rolls are finally changed, and the accumulation of this error will eventually lead to advanced or delayed roll change during roll change and cutting, resulting in roll breakage , then a shutdown correction is required

Embodiment 1

[0037] Such as figure 1 , figure 2 and image 3 As shown, the present invention provides an automatic roll-changing calculation control device for a paper splicer, including a support frame 3 for installing a base paper roll holder 1 and a spare paper roll holder 2, and the base paper roll holder 1 and the backup paper roll holder 2 are both Installed on the support frame 3 through the mandrel 4, and one end of the mandrel 4 is provided with a locking mechanism 5;

[0038] The function of the locking mechanism 5 is to lock the mandrel 4 after the paper roll on the original paper roll holder 1 or the spare paper roll holder 2 is fully used, and its essence can be installed on the motor on one side of the mandrel 4, the motor's A one-way shaft is arranged on the output shaft, and the one-way shaft matches with the end of the mandrel 4, or is other existing mechanisms for locking the shafts.

[0039] The base paper roll holder 1 and the backup paper roll holder 2 are all prov...

Embodiment 2

[0053] An automatic roll-changing operation control method of the splicing machine of the application embodiment 1, comprising the steps of:

[0054] S100. Obtain the consumption rotation rate on the surface of the raw paper roll and the transmission rate of the paper roll through the speed sensor;

[0055] S200. At the same time, acquire the consumption vector data in the radial direction of the raw paper roll through the angle sensor;

[0056] S300. Convert the diameter of the base paper roll through the obtained consumption vector data, and then use the consumption time of the base paper roll at the average speed of the rotation consumption rate, and calibrate through the transmission rate;

[0057] S400. Feedback the calculation of the rotation consumption rate, transmission rate, consumption vector data and consumption time to the drive motor through the controller of the paper splicer, and control the rotation angular velocity of the drive motor through electrical signal...

Abstract

The embodiment of the present invention discloses an automatic roll-changing operation control device for a paper splicer, which includes a support frame for installing a base paper roll frame and a spare paper roll support. On the frame, one end of the mandrel is provided with a locking mechanism, both the original paper roll holder and the spare paper roll holder are provided with a roll counting mechanism, and a transmission roller is arranged on the support frame at the middle top of the original paper roll holder and the spare paper roll holder; and The control method is to obtain the consumption rotation rate of the base paper roll surface and the transmission rate of the paper roll through the speed sensor; and obtain the consumption vector data in the radial direction of the base paper roll through the angle sensor; convert the diameter of the base paper roll through the acquired consumption vector data, Then, the consumption time of the base paper roll is calibrated by the average speed of the rotation consumption rate, and the transmission rate is calibrated, and the real-time feedback method avoids the problem of stopping the calibration and effectively improves the work efficiency.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of gypsum board production, in particular to an automatic roll-changing operation control device and control method for a paper splicer. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one of the new lightweight boards that are currently being developed. Inner partition walls, wall cladding panels (instead of plastering layers), ceilings, sound-absorbing panels, ground-based panels and various decorative panels of various buildings such as office buildings, shops, hotels and industrial plants, etc. It should not be installed in the bathroom or kitchen. [0003] In the existing high-speed gypsum board production control process, the automatic roll changing and automa...
