Background
Glitter powder is also called glitter powder, and glitter pieces (or glitter pieces) with larger particle size are also called glitter pieces, and the glitter pieces are usually formed by precisely cutting a film material with extremely high brightness and a metal coating. The glitter powder is mainly used for surface decoration of articles.
The shapes of the glitter powder commonly used at present are quadrangle, hexagon, rectangle and the like. In most occasions, the glitter powder is required to be uniform in shape and size, and accordingly, a cutting machine (also called glitter powder cutting machine) is used for precisely cutting the film material to form glitter powder with a specific shape (such as a quadrangle, a hexagon, a rectangle and the like). For example, the utility model patent of the applicant's granted publication number CN217597206U discloses a glitter powder cutting machine, which comprises a frame, a film material clamping and conveying device and a film material cutting device; the film material slitting device comprises a strip-shaped fixed knife, a slitting roller and a driving motor, wherein the strip-shaped fixed knife is installed on the rack and is arranged along the horizontal direction, the slitting roller is rotatably installed on the rack and is parallel to the strip-shaped fixed knife, the slitting roller comprises a roller body, a plurality of strip-shaped movable knives capable of being matched with the strip-shaped fixed knife are arranged on the outer surface of the roller body, and each strip-shaped movable knife extends along the axial direction of the roller body and is arranged at equal intervals around the roller body; the driving motor is arranged on the frame, and an output shaft of the driving motor is in transmission connection with one end of the slitting roller; the film material clamping and conveying device comprises two clamping and conveying seats and two conveying belt groups, the two clamping and conveying seats are arranged side by side up and down, and a film material clamping and conveying channel in the front-back direction is formed between the two clamping and conveying seats; the two conveying belt groups correspond to the two clamping seats one by one, each conveying belt group comprises a plurality of conveying belts which are sequentially arranged from left to right, each conveying belt is provided with a film clamping section which moves from front to back, and the film clamping section is arranged in a film clamping channel; the conveying belts of the two conveying belt groups are the same in number and correspond to one another, and the film material clamping sections of the two corresponding conveying belts are arranged oppositely; the strip-shaped fixed knife is positioned at the output port of the film material clamping and conveying channel, and the extending direction of the strip-shaped fixed knife and the moving direction of the film material clamping and conveying section form an included angle which is larger than zero and smaller than 90 degrees. When the film material cutting device works, a film material waiting for powder cutting passes through a film material clamping and conveying channel formed between the two clamping and conveying seats, all the conveying belts synchronously run, the film material clamping and conveying sections of all the conveying belts are used for clamping and conveying the film material clamping and conveying sections together, so that the film material clamping and conveying sections stably move from front to back, and the film material clamping and conveying sections are output through an output port of the film material clamping and conveying channel and then enter the film material cutting device; meanwhile, the driving motor drives the slitting roller to rotate continuously, each strip-shaped movable knife of the slitting roller in a rotating state is matched with the strip-shaped fixed knife, the film conveyed by the film clamping and conveying device is precisely cut, and the film is cut into glitter powder with a specific shape (such as a regular hexagon).
However, there are applications where irregular glitter powder is needed (e.g., adding irregular glitter powder to injection molding materials, paints, materials such as "31689" or "31689materials, etc., can better represent the layering of the appearance of the finished product), i.e., glitter powder is a collection of glitter powders of different shapes and sizes, which contain different shapes and sizes and have uncertainty, such as: the glitter powder can comprise geometrical shapes with different numbers of sides, such as triangles, quadrangles and the like; the glitter powder with the same side number and geometric shape (such as quadrangle) also has different side length and angle.
In order to obtain the glitter powder with irregular shapes, the method adopted at present is as follows: cutting the membrane material by a cutting machine (such as glitter powder cutting machine disclosed in CN 217597206U) to form glitter powder with specific shape (such as quadrangle, hexagon, rectangle, etc.) and large size; then the glitter powder is added into a grinder, the movable knife of the glitter powder is matched with the fixed knife to carry out further cutting or grinding, and as the glitter powder of each piece reaches the position between the movable knife and the fixed knife of the grinder, the glitter powder with irregular shapes can be obtained. However, glitter powder is small in size and light in weight, and easily flies during cutting or crushing to cause pollution to the environment in a workshop, and in the case of cutting and crushing in two steps using two devices (i.e., the cutting machine and the crushing machine), such pollution is increased, and the increase of the number of processes also causes increase of labor intensity of workers and production cost.
