Description

Technical Field

[0001] The utility model relates to equipment and a method for splitting materials into fragments, in particular to a processing mechanism for irregularly shaped glitter powder. Background Art

[0002] Glitter powder, also known as glitter powder, and larger particles are called glitter flakes (or glitter flakes). It is usually made from a highly glossy metal-coated film that is precisely cut. Glitter powder is primarily used for surface decoration.

[0003] Currently, commonly used glitter powder shapes include squares, hexagons, and rectangles. In most applications, uniform glitter powder shapes and sizes are required. Accordingly, a cutting machine (also known as a glitter powder cutter) is used to precisely cut film material into glitter powder with specific shapes (such as squares, hexagons, and rectangles). For example, the applicant's utility model patent, granted publication number CN217597206U, discloses a glitter powder cutter capable of cutting film material into glitter powder with specific shapes (such as regular hexagons).

[0004] However, some applications require irregularly shaped glitter (for example, adding irregularly shaped glitter to injection molding materials, paint, and other materials can enhance the layered appearance of the finished product). Glitter generally consists of a large number of glitters of varying shapes, each containing glitter of varying shapes (and often varying sizes), and the shapes are often uncertain. To obtain such irregularly shaped glitter, a cutting machine (such as the glitter cutting machine disclosed in CN217597206U) can be used to cut the film material to form glitter of a specific shape and larger size. This glitter is then further cut using the cutting equipment. Because the locations of the individual glitter pieces during further cutting are typically random, irregularly shaped glitter can be obtained while also reducing the size of the glitter. However, after further cutting, some glitter is still too large and needs to be sieved out before being re-added to the cutting equipment for further cutting, increasing the labor intensity of the workers. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a processing mechanism for irregularly shaped glitter powder, which can cut larger glitter powder and automatically return the glitter powder that does not meet the required size after cutting to the slitting device for further cutting, thereby obtaining glitter powder of irregular shape but meeting the required size. The technical solution adopted is as follows:

[0006] A processing mechanism for irregularly shaped glitter powder comprises a frame and a slitting device, the slitting device comprises a strip-shaped fixed knife, a slitting roller and a slitting roller driving motor, the strip-shaped fixed knife is arranged in a horizontal direction, the slitting roller is parallel to the strip-shaped fixed knife, the slitting roller comprises a roller body, a plurality of strip-shaped movable knives which can cooperate with the strip-shaped fixed knife are arranged on the outer surface of the roller body, the output shaft of the slitting roller driving motor is transmission-connected to one end of the slitting roller, and is characterized in that: the processing mechanism for irregularly shaped glitter powder further comprises a feeding hopper, a box body and a lifting mechanism; the box body is mounted on the frame, and a slitting chamber and a lifting chamber which are interconnected are provided in the box body, and a shaft which is connected to the slitting chamber is provided on the top of the box body The box body is provided with a feeding port connected to the feeding chamber, and a discharge port connected to the feeding chamber is provided at the bottom of the box body, and a screen is installed at the discharge port; the feeding hopper is installed on the box body, and the bottom opening of the feeding hopper is connected to the feeding port; the strip fixed knife is fixedly installed in the box body, and the slitting roller is rotatably installed on the box body, the strip fixed knife and each strip movable knife are all in the slitting chamber and below the feeding port; the feeding mechanism includes a feeding shaft and a feeding shaft driving motor, the feeding shaft is rotatably installed on the box body and is arranged in the horizontal direction, at least one feeding component is provided on the feeding shaft, and each feeding component is in the feeding chamber, and the output shaft of the feeding shaft driving motor is transmission connected to one end of the feeding shaft.

[0007] When the irregularly shaped glitter processing mechanism described above is in operation, the slitting roller drive motor drives the slitting roller to rotate, causing each strip-shaped movable blade to rotate around the axis of the slitting roller and cooperate with the strip-shaped fixed blade. The lifting shaft drive motor drives the lifting shaft to rotate, and each lifting component rotates around the lifting shaft. Larger glitter powder (larger glitter powder can be obtained by cutting film material using a cutting machine, and its shape is usually regular, such as hexagonal or rectangular) is added from the feeding hopper and falls between the strip-shaped fixed blade and the strip-shaped movable blade, or between two adjacent strip-shaped movable blades. Subsequently, when the glitter powder reaches between the movable blade edge of the strip-shaped movable blade and the fixed blade edge of the strip-shaped fixed blade, the strip-shaped movable blade cooperates with the fixed blade (each strip-shaped movable blade on the slitting roller cooperates with the fixed blade in turn) to cut the glitter powder. After cutting, smaller glitter powder falls from the slitting device and into the lifting chamber. Glitter powder that meets the required size can pass through the screen at the discharge port and be discharged from the box. Glitter powder that still does not meet the required size remains in the box and is lifted by the lifting component and falls between the fixed strip knife and the movable strip knife, or between two adjacent movable strip knives, where it is then cut again by the movable strip knife in conjunction with the fixed strip knife. Furthermore, the lifting component fully disperses the glitter powder in the lifting chamber, preventing glitter powder that does not meet the required size from accumulating on the inner surface of the screen, thereby facilitating the timely passage of glitter powder that meets the required size through the screen. Because each piece of glitter powder is randomly positioned between the movable blade of the movable strip knife and the fixed blade of the fixed strip knife, irregular shapes can be obtained after slitting. Furthermore, the lifting mechanism automatically returns glitter powder that does not meet the required size to the slitting device for further cutting, reducing worker labor intensity.

[0008] The slitting roller drive motor is installed on the frame or on the outer wall of the box; the lifting shaft drive motor is installed on the frame or on the outer wall of the box.

[0009] Typically, the slitting roller is rotatably mounted on the box body by connecting its two ends to the left and right walls of the box body through bearings. The lifting shaft is rotatably mounted on the box body by connecting its two ends to the left and right walls of the box body through bearings. The lifting shaft and slitting roller are parallel to each other.

[0010] In a preferred embodiment, the material raising chamber is located at the rear of the slitting chamber, and the bottom inner wall of the slitting chamber is a sloped surface that gradually slopes downward from front to back. In this way, the glitter powder obtained by the slitting device can slide along the sloped surface toward the material raising chamber after falling, and enter the material raising chamber more smoothly.

[0011] In a preferred embodiment, the fixed blade of the strip-shaped fixed knife is linear and parallel to the axis of the slitting roller; the movable blade of the strip-shaped movable knife is spiral, and an angle is formed between the movable blade of the strip-shaped movable knife and the fixed blade of the strip-shaped fixed knife at the shearing engagement. Preferably, the angle of the above-mentioned angle is 3-6°. In the unfolded plan view of the cylindrical surface on which the movable blade of each strip-shaped movable knife is located, the angle between the movable blade of the strip-shaped movable knife and the generatrix is ​​equal to the angle between the movable blade of the strip-shaped movable knife and the fixed blade of the strip-shaped fixed knife. There is an angle between the movable blade of the strip movable knife and the fixed blade of the strip fixed knife at the shearing cooperation position. When the glitter powder is between the movable blade of the strip movable knife and the fixed blade of the strip fixed knife, the movable blade of the strip movable knife and the fixed blade of the strip fixed knife start to shear from one side of the glitter powder to the other side. The required shearing force is small, and the shearing can be completed more smoothly.

[0012] In another preferred embodiment, the fixed blade of the strip-shaped fixed knife is linear and parallel to the axis of the slitting roller; the movable blade of each strip-shaped movable knife extends along the axial direction of the roller body.

[0013] In a specific solution, the strip-shaped movable knives are arranged at equal intervals in the circumferential direction of the roller body.

[0014] In a preferred embodiment, the material lifting component includes a strip material lifting plate and a plurality of connecting rods. The strip material lifting plate and the material lifting shaft are parallel to each other, and two ends of each connecting rod are respectively connected to the strip material lifting plate and the material lifting shaft.

[0015] In a more preferred embodiment, the screen is curved, with a curvature that matches the circular trajectory of the strip lifting plate. Typically, when the strip lifting plate moves along the circular trajectory to a position corresponding to the screen, a slight gap exists between the strip lifting plate and the inner surface of the screen. As the strip lifting plate moves, glitter powder that meets the required size passes through the screen and is discharged from the box, while glitter powder that does not meet the required size continues to move and is lifted by the strip lifting plate, falling between the fixed strip knife and the movable strip knife, or between two adjacent movable strip knives.

[0016] In a preferred embodiment, the material lifting components are arranged at equal intervals in the circumferential direction of the material lifting shaft.

[0017] Generally, a screen with a corresponding mesh size is selected according to the size of the glitter powder to be obtained.

[0018] In a preferred embodiment, the processing mechanism for the irregularly shaped glitter powder further comprises a material receiving slide, which is mounted on the machine frame and is located below the material discharge port.

[0019] The utility model can cut larger glitter powders and automatically return glitter powders that do not meet the required size to the slitting device for re-cutting through the lifting mechanism. Since the positions of the individual pieces of glitter powder are random when they arrive between the blades of the movable strip knife and the fixed strip knife, glitter powders of irregular shapes that meet the required size can be obtained. The lifting mechanism automatically returns glitter powders that do not meet the required size to the slitting device for re-cutting, which helps reduce the labor intensity of workers.

[0027] In this embodiment, the material raising chamber 42 is located behind the slitting chamber 41. The bottom inner wall 45 of the slitting chamber 41 is an inclined surface that gradually slopes downward from front to back. After the glitter powder is cut by the slitting device, it can slide along this inclined surface toward the material raising chamber 42 and enter the material raising chamber 42 more smoothly.

[0028] refer to Figure 2 and Figure 3 In this embodiment, the fixed blade 211 of the strip fixed blade 21 is straight and parallel to the axis of the slitting roller 22; the movable blade 2221 of the strip movable blade 222 is spiral, and there is an angle α between the movable blade 2221 of the strip movable blade 222 and the fixed blade 211 of the strip fixed blade 21 at the shearing engagement (the angle α is 3-6°).

[0029] The strip-shaped movable blades 222 are arranged at equal intervals in the circumferential direction of the roller body 221 .

[0030] 6References Figure 4 In this embodiment, the lifting member 52 includes a strip-shaped lifting plate 521 and multiple (e.g., three) connecting rods 522. The strip-shaped lifting plate 521 is parallel to the lifting shaft 51, and each connecting rod 522 is connected at both ends to the strip-shaped lifting plate 521 and the lifting shaft 51, respectively. The screen 6 is curved, and its curvature matches the circular trajectory of the strip-shaped lifting plate 521 during operation. (When the strip-shaped lifting plate 521 moves along the circular trajectory to a position corresponding to the screen 6, a slight gap exists between the strip-shaped lifting plate 521 and the inner surface of the screen 6.)

[0031] The material lifting members 52 are arranged at equal intervals in the circumferential direction of the material lifting shaft 51 .

[0032] The processing mechanism of irregular-shaped glitter powder in this embodiment further comprises a material receiving chute 7, which is mounted on the frame 1 and below the discharge port 44. The material receiving chute 7 is gradually inclined downward from front to back.

[0033] The following is a brief description of the working principle of the irregular shape glitter powder processing mechanism:

[0034] During operation, the slitting roller driving motor drives the slitting roller 22 to rotate, and each strip-shaped movable knife 222 rotates around the axis of the slitting roller 22 and cooperates with the strip-shaped fixed knife 21. The lifting shaft driving motor drives the lifting shaft 51 to rotate, and each lifting component 52 rotates around the lifting shaft 51. Large-sized glitter powder is added from the feeding hopper 3 (large-sized glitter powder can be obtained by cutting the film material with a cutting machine, and its shape is usually regular, such as hexagonal, rectangular, etc.). These large-sized glitter powders fall between the strip-shaped fixed knife 21 and the strip-shaped movable knife 222 or between two adjacent strip-shaped movable knives 222; then, when the glitter powder 8 reaches between the movable knife edge 2221 of the strip-shaped movable knife and the fixed knife edge 211 of the strip-shaped fixed knife (refer to Figure 3), the strip-shaped movable blade 222 cooperates with the strip-shaped fixed blade 21 (each strip-shaped movable blade on the slitting roller cooperates with the strip-shaped fixed blade in turn) to cut the glitter powder 8. After cutting, the smaller glitter powder falls from the slitting device and enters the lifting chamber 42. The glitter powder that meets the required size can pass through the screen 6 at the discharge port 44 and be discharged from the box 4, falling onto the receiving chute 7 for collection. The glitter powder that still does not meet the required size remains in the box 4 and can be lifted by the lifting component 52 and fall between the strip-shaped fixed blade 21 and the strip-shaped movable blade 222 or between two adjacent strip-shaped movable blades 222. It is then cut again by the strip-shaped movable blade 222 in cooperation with the strip-shaped fixed blade 21.

[0035] In addition, under the stirring of the lifting component 52, the glitter powder in the lifting chamber 42 can be fully dispersed, and the glitter powder that still does not meet the requirements is prevented from accumulating on the inner surface of the screen 6, which is conducive to the glitter powder that meets the requirements passing through the screen 6 in time.

[0036] In other embodiments, the fixed blade of the strip-shaped fixed knife is linear and parallel to the axis of the slitting roller; the movable blade of each strip-shaped movable knife extends along the axial direction of the roller body.
