Detailed implementation manners

[0024] The following combines the accompanying drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0025] "Horizontal" and "surface" are referenced based on the normal use state of the short fiber production device for fiber bundles. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0026] In addition, terms such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the creation of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0027] As Figures 1 - 3 shown, a short fiber production device for fiber bundles disclosed by the present utility model includes a base 1, a cutting member 2, a pressing member 3, and a winding channel 222. The base 1 is provided with a collection chamber 10 and a feeding port 11; the cutting member 2 is rotatably connected to the base 1 around a first rotation center line, includes a plurality of tool grooves 20 extending along the first rotation center line and arranged around it, and a central accommodating portion 200 surrounded by the tool grooves 20, and is connected to a power source 100; the pressing member 3 rotates around a second rotation center line and is adjusted to abut against or separate from the tool grooves 20 through a distance adjusting member 31; the winding channel 222 is clamped between the pressing member 3 and the cutting member 2; the extending directions of the first rotation center line and the second rotation center line are both consistent with the horizontal direction, the notch of the tool groove 20 is set facing away from the first rotation center line, a fiber channel 201 communicating with the central accommodating portion 200 is provided between adjacent tool grooves 20, and the central accommodating portion 200 is provided with an opening facing the collection chamber 10.

[0028] The fiber bundle is fixed on the circumferential side of the cutting member 2 through the winding channel 200, and abuts against the cutting edge installed on the tool groove 20 through the pressing member 3. The fiber cutting is completed by using the cutting force along the abutting direction. The short fibers are squeezed into the central accommodating portion 200 through the fiber channel 201, then fall into the collection chamber 10, and are sent to the next process.

[0029] By rotating the cutting member 2 to abut and cooperate with the cutting edge of the pre-installed blade on the tool groove 20, the cut short fibers fall from the central accommodating portion 200 to the collection chamber 10, realizing the cutting of the fiber bundle and continuous production, and improving production efficiency; in some embodiments, different lengths of fibers can be cut by arranging cutting members 2 with different intervals between the tool grooves 20; in another embodiment, different lengths of fibers can be cut by adjusting the installation interval between the pre-installed blades on the tool groove 20.

[0030] The discharge port 13 of the collection chamber 10 is connected to a vacuum chamber (a device in the next process, not shown). Therefore, the diameter of the discharge port 13 gradually decreases along the discharge direction, preventing the vacuum degree of the vacuum chamber from rising too fast, resulting in incomplete discharge of the short fibers. At the same time, the inclined surface of the discharge port 13 is beneficial to the sliding of the short fibers.

[0031] As Figure 3 shown, the structure of the cutting member is optimized to facilitate the installation and fixation of the blade, and the connection between the detachable cutting member 2 and the base 1. The cutting member 2 includes a bottom plate 21, an annular pressing plate 22 and an annular baffle 23 arranged concentrically. A plurality of tool grooves 20 are clamped between the bottom plate 21 and the annular pressing plate 22. The bottom plate 21 is fixedly connected to the power source 100. The annular pressing plate 22 is provided with a through hole 220 communicating with the tool groove 20. The annular baffle 23 covers the surface of the annular pressing plate 22 and blocks the through hole 220. The bottom plate 21 and the power source 100 are connected by a nut, and the power source 100 is a motor.

[0032] The inner diameters of the bottom plate 21, the annular pressing plate 22 and the annular baffle 23 all determine the size of the opening of the central accommodating portion 100. The outer diameter of the annular baffle 23 can adjust the depth of the winding channel 222. Further, the inner diameter of the annular baffle 23 is equal to or greater than the inner diameter of the annular pressing plate 22, and the outer diameter of the annular baffle 23 is equal to or greater than the outer diameter of the annular pressing plate 22. The outer edge of the annular baffle 23 is provided with a folded edge 230, and the folded edge 230 extends towards the collection chamber 10. The base 1 is provided with an installation chamber for the cutting member 2. Generally, the space of the installation chamber is larger than the specification of the cutting member 2 to facilitate installation. Because there is a gap between the cutting member 2 and the base 1 after installation, the setting of the folded edge 230 prevents the cut short fibers from falling into the gap, which not only affects the rotation of the cutting member 2 but also the collection efficiency of the short fibers.

[0033] Optimize the depth of the winding channel 222. The outer diameters of the bottom plate 21 and the annular pressing plate 22 are equal. The distance from the cutter groove 20 to the inner diameter of the annular pressing plate 22 is less than the distance to the outer diameter of the annular pressing plate 22. The depth of the winding channel 222 determines the number of turns of the fiber bundle winding and the magnitude of the abutting force.

[0034] The feeding port 11 is provided in a long and narrow shape. The extending direction of the feeding port 11 is perpendicular to the first rotation center line. The feeding port 11 and the pressing member 3 are respectively arranged on both sides of the cutting member 2. The feeding port 11 which is long and narrow and has an extending direction perpendicular to the first rotation center line is beneficial for multi-layer wide fiber bundles to converge on the winding channel 222 with a fixed width. In order for the fiber bundle to smoothly enter the feeding port 11 and be fixed, and at the same time ensure the length of the traction section, the feeding port 11 and the pressing member 3 are respectively arranged on both sides of the cutting member 2, which is also beneficial for the equipment to be set in a smaller size and reduce the floor area. An opening is provided on the side of the base 1 close to the pressing member 3, which helps to observe the fiber bundle wound on the winding channel 222 and observe and adjust the distance between the pressing member 3 and the cutting member 2 when they approach each other.

[0035] The collection chamber 10 is provided with an operation window 12 facing the opening of the central accommodating portion 200. The operation window 12 is provided with a transparent glass window (not shown), which is convenient for observing the cutting condition of the short fiber bundle and installing or replacing the cutting member 2. The transparent glass window can be opened.

A fiber channel 201 communicating with the central accommodating portion 200 is arranged between adjacent cutter grooves 20, and the central accommodating portion 200 is provided with an opening facing the collection chamber 10.

[0038] Among them, the cutting member 2 includes a bottom plate 21, an annular pressing plate 22 and an annular baffle 23 which are concentrically arranged. A plurality of knife grooves 20 are clamped between the bottom plate 21 and the annular pressing plate 22. The bottom plate 21 is fixedly connected to the power source 100. The annular pressing plate 22 is provided with a perforation 220 communicating with the knife groove 20. The annular baffle 23 covers the surface of the annular pressing plate 22 and blocks the perforation 220. The cutting member 2 of this structure is convenient for assembling and replacing parts.

[0039] The feed inlet 11 is arranged in a long and narrow shape, and the extending direction of the feed inlet 11 is perpendicular to the first rotation center line.
