[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a kind of glass fiber short cutter roller, including roller body 1, installation shaft 2 is connected on roller body 1, the surface of roller body 1 is also provided with installation groove 3, closing plug 4 is arranged in installation groove 3, clamping block 5 and cutter 6 are also respectively arranged in installation groove 3, clamping block 5 is located at the two sides of cutter 6, the inner wall of installation groove 3 is also provided with blocking slot 7, the outer side of cutter 6 is also provided with blocking strip 8, installation convex strip 9 is arranged on blocking strip 8, and installation convex strip 9 is located in blocking slot 7.

[0019] Installation groove 3 is distributed on the surface of roller body 1 at equal angles, so that cutter 6 is evenly installed on roller body 1 through installation groove 3 according to specific use requirement. ​

[0020] The closing plug 4 is embedded in the mounting groove 3, one end of the closing plug 4 protrudes from the opening plane of the mounting groove 3, facilitating the closing plug 4 to close the idle mounting groove 3, avoiding the glass fiber being clamped into the idle mounting groove 3, and the one end of the closing plug 4 protruding from the opening plane of the mounting groove 3 is conducive to taking out the closing plug 4 from the mounting groove 3.

[0021] The supporting block 5 is clamped on both sides of the cutter 6, and the supporting block 5 and the cutter 6 are clamped and installed in the mounting groove 3, thereby improving the stability of the cutter 6 installation and avoiding the cutter 6 from shaking left and right during use.

[0022] The cutter 6 is protruded from the opening plane of the mounting groove 3 away from the supporting block 5, facilitating the cutter 6 to cut the glass fiber, and the cutter 6 is distributed at equal angles on the roller body 1, and the cutter 6 distributed at equal angles is conducive to cutting the glass fiber to equal length.

[0023] The blocking strip 8 is made of rubber, the blocking strip 8 is symmetrically distributed on the surface of the cutter 6, the end of the blocking strip 8 away from the mounting protrusion 9 is flush with the cutting edge of the cutter 6, and the inner wall of the blocking strip 8 is attached to the cutting edge of the cutter 6, thereby protecting the cutting edge of the cutter 6 and blocking the glass fiber debris, and avoiding the debris from being clamped into the gap between the cutter 6 and the mounting groove 3.

[0024] Working principle: according to Figures 1-4 As shown in the figure, first, the cutter 6 is installed according to the length cutting requirement of the glass fiber, the supporting block 5 is clamped on both sides of the cutter 6, then the supporting block 5 with the cutter 6 is inserted into the mounting groove 3, at this time the cutter 6 is installed, then the rubber blocking strip 8 is clamped into the clamping groove 7 through the mounting protrusion 9, at this time the blocking strip 8 is installed on both sides of the cutter 6, then the idle mounting groove 3 is closed by the closing plug 4, avoiding the glass fiber being clamped into the idle mounting groove 3.

[0025] When the roller body 1 rotates to drive the cutter 6 to extrude and cut the glass fiber, the rubber blocking strip 8 on both sides of the cutter 6 is abutted against the glass fiber, avoiding the glass fiber from deviating and displacing, and when the cutter 6 cuts the glass fiber, the rubber blocking strip 8 is pushed by the glass fiber on both sides of the cutting edge of the cutter 6 and is attached to the side surface of the cutter 6, thereby preventing the glass fiber from being clamped into the gap between the cutter 6 and the mounting groove 3.
