The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] A carbon fiber cloth perforated compaction device, such as Figures 1 to 6 As shown, the workbench 100 is provided. Roller frame assemblies 200 are provided on the top of the workbench 100 near the left and right sides. Two sets of upright plates 110 are fixed at the bottom of the workbench 100. A notch 102 is provided at the center of the top of the workbench 100. A punching assembly 130 extending into the notch 102 is installed below the workbench 100.

[0029] The punching assembly 130 includes a drive motor 131 installed inside a set of upright plates 110. The output end of the drive motor 131 is provided with a drive shaft 132 that is rotatably connected to the inner wall of another set of upright plates 110. Two sets of driven discs 133 are fixed on the outer wall of the drive shaft 132. Elliptical grooves 1331 are opened at the front and rear ends of the driven discs 133. A U-frame 134 is sleeved on the outer wall of the two sets of driven discs 133. Rollers 1341 extending into the elliptical grooves 1331 are rotatably provided on the inner wall of the U-frame 134. A base plate 135 is fixed on the top of the U-frame 134. Multiple sets of conical spikes 139 are assembled on the top of the base plate 135. A perforated plate 136 installed on the inner wall of the notch 102 is sleeved on the outer wall of the multiple sets of conical spikes 139. A sponge sheet 137 is fixed on the inner wall of the perforated plate 136. A cross groove 138 for the conical spikes 139 to pass through is opened on the top of the sponge sheet 137.

[0030] The carbon fiber cloth to be drilled is installed on the roller shaft frame assembly 200, and the free end of the carbon fiber cloth is pulled over from under the auxiliary rod 250, then over another set of auxiliary rods 250, and finally fixed on the outer wall of the winding drum 240 in another set of roller shaft frame assemblies 200. At this time, the driving motor 131 can be controlled to work, and its output end will drive the driving shaft 132 to rotate, and the driven disc 133 on the outer wall will rotate synchronously, and the oval groove 1331 on the end surface will drive the U-shaped frame 134 and the top fixed base plate 135 to move up and down through the roller 1341. When the taper 139 is inserted into the carbon fiber cloth to complete the drilling, the taper will pass through the inside of the sponge sheet 137 and be located below it when it is lowered, and the cross groove 138 can make the sponge sheet 137 fully contact with the taper 139, so that the friction between them is larger, which can better remove the residual fiber silk (wiring strip) on the outer wall of the taper 139, and the groove coefficient of the outer surface of the sponge sheet 137 is larger, which can better stick the fiber silk (wiring strip), so that the dyeing phenomenon does not occur when drilling other color carbon fiber cloth, so as to improve the quality of the device for drilling carbon fiber cloth.

[0031] Please refer to Figure 4 , a plurality of tapers 139 are arranged in four columns in the longitudinal direction, and each column of tapers 139 has a connecting strip 1391 fixed at the bottom end. The sidewall of the base plate 135 is provided with a bolt extending into the interior for fixing the connecting strip 1391.

[0032] It is convenient to disassemble and replace the tapers 139 to meet the needs of rolling different size holes in the fiber cloth.

[0033] Please refer to Figure 1 and Figure 2 , a plurality of partition strips are fixed on the inner wall of the notch 102 near the top of the workbench 100, and the spacing between the two connected partition strips corresponds to the taper 139;

[0034] The auxiliary frame 101 is fixed on the top of the workbench 100 outside the notch 102.

[0035] The partition strips can divide the size of the space at the top of the notch 102 to prevent the falling of the object into the notch 102 and affect the lifting of the tapers 139. The auxiliary frame 101 allows the carbon fiber cloth to have a certain gap with the top of the workbench 100 to prevent the carbon fiber cloth from being scratched by friction when the two are in contact.

[0036] Please refer to Figure 5The roller shaft support assembly 200 comprises a first triangular plate 210 fixed on the top of the workbench 100 and close to the rear surface, a second triangular plate 220 movably arranged on the top of the workbench 100 and close to the front surface, a rotating shaft 230 rotatably connected to the side of the first triangular plate 210 close to the second triangular plate 220, and a winding drum 240 movably arranged on the outer wall of the rotating shaft 230.

[0037] The second triangular plate 220 is rotatably arranged with a handle 222 on the side away from the first triangular plate 210, and the end of the handle 222 extends into the end of the rotating shaft 230, and the end surface of the rotating shaft 230 is provided with a blind hole for hiding the handle 222.

[0038] The bottom of the second triangular plate 220 is fixed with a constraint strip 221, and the top of the workbench 100 is provided with a positioning groove matched with the constraint strip 221.

[0039] When the winding drum 240 and the outer wall of the wound carbon fiber cloth are removed, the auxiliary tool is placed on the bottom of the carbon fiber cloth and the outer wall is contacted, and then the handle 222 is rotatable and separated from the rotating shaft 230, at this time, the second triangular plate 220 is pulled upward to separate from the workbench 100, and the winding drum 240 and the outer wall of the wound carbon fiber cloth are exposed, and the auxiliary tool is operated to remove the winding drum 240 and the outer wall of the wound carbon fiber cloth.

[0040] Please refer to Figure 1 and Figure 2 The outer wall of the vertical plate 110 is rotatably connected with a first pulley fixed on the end of the driving shaft 132, and the outer wall of the first triangular plate 210 is rotatably connected with a second pulley fixed on the end of the rotating shaft 230, and the first pulley and the second pulley are connected with a belt 120.

[0041] The use of the belt 120 synchronizes the rotating speed of the driving shaft 132 and the rotating shaft 230, ensures that the wound carbon fiber cloth will not wrinkle, and realizes the high quality of the hole of the carbon fiber cloth.

[0042] In use, the carbon fiber cloth to be pierced is installed on the roller shaft frame assembly 200, and the free end of the carbon fiber cloth is pulled to pass under the auxiliary rod 250, then to pass under another set of auxiliary rods 250, and finally to be fixed on the outer wall of the winding drum 240 in another set of roller shaft frame assemblies 200. At this time, the driving motor 131 can be controlled to work, and the output end of the driving motor 131 drives the driving shaft 132 to rotate, and the driven disc 133 on the outer wall rotates synchronously, and the elliptical groove 1331 on the end surface of the driven disc 133 drives the U-shaped frame 134 and the top-fixed base plate 135 to move up and down through the roller 1341, so that the conical spike 139 can be inserted into the carbon fiber cloth to complete the piercing when the U-shaped frame 134 and the top-fixed base plate 135 are raised, and the conical spike 139 can pass through the inside of the sponge sheet 137 and be located below the sponge sheet 137 when the U-shaped frame 134 and the top-fixed base plate 135 are lowered, and the cross-shaped groove 138 can make the sponge sheet 137 fully contact with the conical spike 139, so that the friction between the sponge sheet 137 and the conical spike 139 is larger, and the fiber silk (wiring strip) on the outer wall of the conical spike 139 can be better removed, and the groove coefficient of the outer surface of the sponge sheet 137 is larger, so that the fiber silk (wiring strip) can be better adhered, and the subsequent piercing of the carbon fiber cloth of other colors will not cause the phenomenon of dyeing, so that the quality of the piercing of the carbon fiber cloth by the device can be improved, and the parts not involved in the device are the same as or can be realized by the prior art.
