Description
Technical Field
The invention relates to the field of shearing functions of belt cutters, in particular to a rolling and cutting device.
Background
The belt cutting machine is special equipment for cutting auxiliary materials and materials in fixed length by manufacturers such as clothing making, shoe making and bag making, the functions of the belt cutting machine are continuously improved along with market demands along with innovation of sewn product design and continuous change of pattern varieties of the auxiliary materials and the materials, and in order to enhance working efficiency, rolling cutting technologies in other fields are also applied to the belt cutting machine field, so that the cross-industry technology brings more business opportunities for the belt cutting machine industry; however, most of the existing rolling technology uses a motor to drive a hob to rotate at uniform speed and circulate, and patterns to be rolled are engraved on the hob to roll woven belts, materials and the like in a single-circle continuous uniform-speed rotation mode; the feeding of the rotary cutter drives the material to perform feeding action by the rolling of the rotary cutter, and the feeding device is added to some products, but the rotary cutter only maintains the same rolling speed as the rotary cutter to assist in uniformly conveying the material; the inventor applies for and obtains the Chinese patent of patent number ZL201721078767.1 of a stocking blanking machine in 2017 and 25, adopts the rolling and cutting technology, and can fully distribute the blade on the circumferential surface of the whole hob, so the rolling and cutting technology only limits the webbing, materials and the like used for cold cutting and fixing the size and shape to cut, and can not realize the cutting function and hot cutting function which are the same as a belt cutting machine and can randomly adjust the length; in order to realize the random length adjustment with the hot cutting and shearing functions, the inventor applies for and obtains the Chinese patent with the patent number ZL201721142798.9 by the patent name of a novel ultrasonic belt cutter on the 2017, the 09 and 07 date, adopts a hob cutter to combine ultrasonic waves to carry out hot cutting and rolling and cutting on materials such as a braid, and the rolling and cutting actions of the hob cutter are different from those of a stocking blanking machine and a hob cutter with the patent number ZL 201721078767.1; the cutter blades are not fully distributed on the circumferential surface of the whole hob, but the cutter blades are arranged on one half of the circumference of the hob, the cutter blades cannot be arranged on the other half of the circumferential surface of the hob, and the part without the cutter blades can be recessed more than the space for the woven belts and materials to pass through; the rotary motion is not single-circle continuous uniform rotation, but the rotary speed when the position of the blade part on the circumferential surface of the hob contacts with the mesh belt and the material is the same as the conveying speed of the feeding mechanism, the other part does not have the blade, and the rotary speed when the circumferential surface part with a concave space in the middle contacts with the mesh belt and the material is changed: if the short webbing is rolled, the rotation speed of the position without the blade or the position with the hollow space circumference surface in the middle can roll rapidly, and the conveying speed of the feeding mechanism can be exceeded; if the long webbing is rolled, the rotation speed of the part without the blade, namely the part with the hollow space circumference surface in the middle, is slower than the conveying speed of the feeding mechanism, so that the sufficient time for conveying the webbing can be ensured; the method for changing the speed in a circle of rolling and matching with each other can replace the up-and-down motion of the cutter, realize the rolling and cutting function and the hot cutting function which can randomly adjust the length, and adapt to the current market demands with higher efficiency; however, it must be used in combination with ultrasonic equipment to make only hot cuts, and if necessary cold cutting functions are not possible.
