Production method of electromagnetic welding type cleaning brushes and sealing brushes and application thereof

Abstract

The invention relates to a production method of electromagnetic welding type cleaning brushes and sealing brushes in the field of cleaning brushes and sealing brushes. The production method comprises the following steps: i. an electronic circuit board is electrified to generate an alternating magnetic field; ii. a sheet is placed in the region of the alternating magnetic field generated by the electronic circuit board; iii. a fiber material is placed at one end of a support board, wherein the end of the support board is provided with a steel bar, and the fiber materialis in contact with the end of the support board; iv. the end of the support board, which is provided with the steel bar, does the motion of cutting magnetic lines of force in the alternating magnetic filed generated by the electronic circuit board so that the steel bar generates vortexes; v. under the action of the vortexes, iron molecules in the steel bar do high-speed irregular motion, collide and rub with each other to generate heat energy, the steel bar generate heat rapidly, and the heat of the steel bar is transmitted to the sheet and the fiber material; and vi. the contact parts of the sheet and the fiber material are welded together after the heat of the steel is transmitted to the sheet and the fiber material. The invention has the advantages of large welding area, even welding, no pollution, high productivity and lower production cost.

Description

technical field [0001] The present invention relates to the production method and application of cleaning brushes and sealing brushes, in particular to the method of manufacturing cleaning brushes and sealing brushes by electromagnetically welding sheets and fiber materials and the uses of the cleaning brushes and sealing brushes produced by this method. Background technique [0002] At present, the production process of combining the bristles of cleaning brushes and sealing brushes of printers and copiers with the brush handle on the market mainly includes two manufacturing methods: weaving process and ultrasonic welding process. The production methods of weaving process to manufacture cleaning brushes and sealing brushes have the following disadvantages: A. Because the base material is soft after weaving, it is not convenient to install the cleaning brush and sealing brush on the terminal machine, so it can only be bonded, but the bonding has disadvantages such as poor stab...

[0002] At present, the production process of combining the bristles of cleaning brushes and sealing brushes of printers and copiers with the brush handle on the market mainly includes two manufacturing methods: weaving process and ultrasonic welding process. The production methods of weaving process to manufacture cleaning brushes and sealing brushes have the following disadvantages: A. Because the base material is soft after weaving, it is not convenient to install the cleaning brush and sealing brush on the terminal machine, so it can only be bonded, but the bonding has disadvantages such as poor stability and cannot be placed in a high temperature place; B. 1. The weaving process with high production cost must use autocratic weaving machines, and the market price of such machines is relatively high; C. Low production efficiency D. Poor production quality

[0003] For example, the U.S. Patent No. US.NO.7419555 relates to a method for welding fiber materials by ultrasonic technology. Ultrasonic welding is to transmit sound waves to the welding head and then to the plastic processing object. The amplitude makes the two plastic parts rub against each other violently, and instantly welds the plastic joint surface quickly. The advantage of this welding method is that the ultrasonic welding process has the advantages of easy installation, high production efficiency, and high production quality compared with the braiding process; but it also has the following disadvantages : a. The welding process with high production cost must use a proprietary ultrasonic welding machine. The force is small, and there is a hidden danger of "hair removal and hair loss"
