Automatic paper feeding device of tissue paper machine

Abstract

The invention discloses an automatic paper feeding device for a paper towel machine, which is arranged at the front end of the paper towel machine and used to provide paper towels for the paper towel machine, including a frame, a conveying device and a supporting device. The groove of the roll; the conveying device can provide power for the paper roll to convey the paper towel to the paper towel machine; the supporting device is used to support the conveying device; the bottom of the groove is provided with a weight sensor for monitoring the paper roll weight, and generate electrical signals; the supporting device includes a controller; the controller is connected with the weight sensor, receives the electrical signal from the weight sensor, and controls the supporting device to provide appropriate supporting force, and adjusts the conveying device and the paper roll pressure between. The present invention uses a controller to control the supporting device to provide proper supporting force for the conveying device, and changes are made at any time as the weight of the paper roll changes.

Description

technical field [0001] The invention relates to the field of paper towel machines, in particular to an automatic paper feeding device for a paper towel machine. Background technique [0002] At present, there are two main types of paper towel machine feeding and cutting, manual and motor-driven. The manual mechanism is composed of a roller, a pressure wheel, a sawtooth knife, and a tension spring. The pressure wheel presses the paper on the roller, and the paper is pulled out by hand. The paper is driven by friction to roll the roller. The serrated knife is installed on the roller, and slowly stretches out as the roller rolls until the paper is cut. , The defect of this mechanism is that paper feeding and cutting must be powered by hand, the length of paper feeding cannot be adjusted, the cutting is not thorough, and the section is not smooth. [0003] So there is a paper towel machine with automatic paper feeding and paper cutting on the market, which includes a frame, a m...

Problems solved by technology

[0002] There are two main types of paper feeding and cutting in the current paper towel machine, manual and motor-driven. The manual mechanism is composed of a roller, a pressure wheel, a sawtooth knife, and a tension spring. The pressure wheel presses the paper on the roller, and the paper is pulled out by hand. The paper is driven by friction to roll the roller. The sawtooth knife is installed on the roller, and slowly stretches out as the roller rolls until the paper is cut. , the defect of this mechanism is that paper feeding and cutting must be powered by hand, the length of paper feeding cannot be adjusted, the cutting is not complete, and the section is not smooth

[0003] So there is a paper towel machine with automatic paper feeding and paper cutting on the market, which includes a frame, a mandrel is arranged in the frame, a paper towel tube is worn on the mandrel, and the paper towels on the paper towel tube are installed on the paper feeding machine. In the gap between the driving shaft and the driven shaft of the device, when using paper, start the paper feeding device to drive the paper towel cylinder to rotate around the core shaft and send out a section of paper towels, and cut the paper towels under the action of the paper cutting device. Because the existing paper towel machine uses two motors to drive the paper feeding device and the paper cutting device respectively, it not only makes the electrical control complicated, but also uses two motors to increase the volume of the paper towel machine, so it is difficult to meet people's use requirements

[0004] The paper feeding device in the prior art mostly uses a fixed connection and an elastic steel sheet to make the conveying device contact with the paper roll. Since the fixed connection is used, the conveying device will always be subjected to a supporting force, and its pressure on the paper roll Timely changes cannot be made according to the size and weight of the paper roll. For example, when the paper roll is just used, the conveying device will be under a very large pressure due to the large paper roll, which makes the pressure between the conveying device and the paper roll very large. The conveying device will cause damage such as embossing and deformation to the paper roll
