[0002] Carbon fiber is a new type of fiber material with high strength and high modulus fiber with a carbon content of more than 95%. Graphite fiber contains more than 99% carbon. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber after carbonization and graphitization. Carbon fiber has many excellent properties.

[0005] Based on the above search and in combination with the prior art, it is found that during the preforming of the existing carbon fiber badminton racket, the staff is required to manually place the carbon fiber strips on the preforming template, which results in a low preforming efficiency of the subsequent carbon fiber badminton racket, and the entire preforming process can only make the racket form a semi-arc shape, and cannot form a complete badminton racket frame, which cannot meet people's preforming needs for badminton rackets. Therefore, a preforming device for the production of carbon fiber badminton rackets is proposed to improve the above problems. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a preforming device for producing carbon fiber badminton rackets, comprising: Box; A bracket, wherein the bracket is fixedly connected to the bottom outer wall of the box body, a top plate is fixedly connected to the top outer wall of the box body, a through slot is formed on the top of the box body and the top plate, and a conveyor belt is provided inside the through slot; First carbon fiber strips, the first carbon fiber strips are equidistantly distributed on the top of the conveyor belt, the top outer wall of the top plate is fixedly connected with a guard plate, the number of the guard plates is two groups, and the two groups of guard plates are respectively arranged on both sides of the conveyor belt; A console, the console is fixedly connected to an outer wall of one side of the box body, and a fixed cover is fixedly connected to the top outer wall of the top plate; A mold platform, the mold platform is arranged above the top plate, a second carbon fiber strip is wound around the outer wall of the mold platform, and the first carbon fiber strip and the second carbon fiber strip have the same specifications; a forming assembly for winding the second carbon fiber strip; Lift the assembly.

[0008] In the above, the forming assembly includes an extrusion roller arranged above the top plate, a positioning groove is opened on the circumferential outer wall of the extrusion roller, the cross-section of the positioning groove is a right-angled trapezoid, the positioning grooves are distributed in a quarter circle on the circumferential outer wall of the extrusion roller, a pressure groove is opened on one side of the positioning groove, and the pressure groove is connected to the positioning groove.

[0009] As a further supplement to the present application, in the process of the molding component driving the extrusion roller to move, the positioning groove and the pressing groove can be used to limit the movement of the first carbon fiber strip, ensuring that one side of the first carbon fiber strip is inserted into the positioning groove, so that the movement of the extrusion roller drives the movement of the first carbon fiber strip.

[0011] As another improvement supplement to the present application, the staff places the first carbon fiber strip on the conveyor belt in sequence, and then starts the conveyor belt to realize automatic conveyance of the first carbon fiber strip. When the conveyor belt conveys the first carbon fiber strip to one side of the mold table, the first motor and the second motor are started at the same time, and the second motor can be used to drive the second threaded sleeve to drive the extrusion roller under the mounting seat to move horizontally to push the first carbon fiber strip to the mold table. Then the first motor drives the first threaded screw to rotate, which can effectively drive the mounting seat to move along the Z-axis direction, and the second threaded sleeve drives the extrusion roller to move along the X-axis direction. The electric push rod above the extrusion roller can drive it to move along the Y-axis direction, so that the first carbon fiber strip can be pressed against the outer wall of the mold table through the extrusion roller to form a second carbon fiber strip in the shape of a racket frame. The whole process has a high degree of automation, which also improves the forming rate of the first carbon fiber strip.

[0012] As another improvement of the present application, the lifting assembly includes a third motor fixedly connected to the inner wall of the bottom of the box body, the output end of the third motor is fixedly connected to a third threaded screw, the circumferential outer wall of the third threaded screw is meshed with a fourth threaded sleeve, and one side outer wall of the fourth threaded sleeve is fixedly connected to a cross bar, the inner walls of both sides of the box body are respectively fixedly connected to the first shell and the second shell, the fourth threaded sleeve is located inside the second shell, the outer walls of both sides of the cross bar are fixedly connected to an inclined rod, one end of the inclined rod is fixedly connected to the bottom outer wall of the mold platform, the top outer wall of the box body is provided with a lifting groove, and the lifting groove is adapted to the mold platform, the inner walls of both sides of the first shell are fixedly connected to third guide rods, the circumferential outer wall of the third guide rod is sleeved with a second guide cylinder, and one end of the cross rod away from the fourth threaded sleeve is fixedly connected to one side outer wall of the second guide cylinder.

[0013] As another improvement supplement of the present application, the third motor can drive the third threaded screw to rotate, and during the rotation of the third threaded screw, the cross bar can be driven to rise as a whole. The rise of the cross bar can lift up the mold platform located in the lifting groove, thereby enabling the second carbon fiber strip to be quickly separated from the mold platform.

[0014] As another improvement of the present application, the top outer wall of the third threaded screw is fixedly connected to a rotating column, the circumferential outer wall of the rotating column is fixedly connected to the first bevel gear, the first bevel gear is meshed with the second bevel gear, the top outer wall of the second shell is fixedly connected to a vertical plate, one side outer wall of the vertical plate is fixedly rotatably connected to the second threaded screw, one end of the second threaded screw is fixedly connected to the one side outer wall of the second bevel gear, the circumferential outer wall of the second threaded screw is meshed with a third threaded sleeve, the top outer wall of the third threaded sleeve is fixedly connected to a third guide cylinder, the inside of the third guide cylinder is plugged with a second guide rod, the two ends of the second guide rod are respectively fixedly connected to the one side outer wall of the vertical plate and the one side inner wall of the box body, the top outer wall of the third guide cylinder is fixedly connected to a push plate, the bottom outer wall of the mold platform is provided with a storage groove, the push plate is located inside the storage groove, and the one side outer wall of the fixed cover is provided with a push groove.

[0015] As another improvement supplement to the present application, during the rotation of the third threaded screw, the rotating column can be driven to rotate, and the rotation of the rotating column can drive the first bevel gear to rotate. During the rotation of the first bevel gear, the second bevel gear can be driven to rotate. When the second bevel gear rotates, the second threaded screw can be driven to rotate. The rotation of the second threaded screw can drive the third guide cylinder at its top to move along the Z-axis direction. During the movement of the third guide cylinder along the Z-axis direction, a push plate is fixedly connected to its top, so that the push plate follows the third guide cylinder to move along the Z-axis direction, which can effectively push the formed second carbon fiber strip out of the push trough, thereby completing the unloading of the second carbon fiber strip.

[0016] As another improvement of the present application, the bottom outer wall of the mold table is fixedly connected to a support plate, the circumferential outer wall of the support plate is fixedly connected to an airbag, the specifications of the airbag are compatible with the specifications of the mold table, a pressure sensor is arranged inside the airbag, and the pressure sensor is electrically connected to the console.

[0017] As another improvement supplement of the present application, when the mold platform is lifted up, the support plate fixed underneath it will also rise together. When the support plate rises to the same horizontal plane as the second carbon fiber strip, the circumferential inner wall of the second carbon fiber strip will contact the airbag on the outer wall of the support plate. In the process of the airbag and the second carbon fiber strip contacting and rising, the airbag and the second carbon fiber strip are in contact. If the structure of the second carbon fiber strip is uniform, there is no obvious extrusion between the airbag and the second carbon fiber strip, and the pressure data of the pressure sensor remains within the standard range. On the contrary, if the pressure sensor data increases significantly, it means that the two are squeezed more, or decreases significantly, it means that the two are suddenly out of contact, both of which indicate that the structure of the second carbon fiber strip does not meet the standards, thereby realizing quality inspection of the second carbon fiber strip that has been produced.

[0018] In summary, after adopting the above structure, the present invention has the following advantages compared with the prior art: 1. The above-mentioned conveyor belt and forming assembly can realize automatic preforming of carbon fiber badminton rackets, and the whole forming process does not require manual intervention, which effectively improves the forming efficiency of carbon fiber badminton rackets. Specifically, the staff places the first carbon fiber strip on the conveyor belt in sequence, and then starts the conveyor belt to realize automatic conveying of the first carbon fiber strip. When the conveyor belt conveys the first carbon fiber strip to one side of the mold table, the first motor and the second motor are started at the same time. The second motor can make the second threaded sleeve drive the extrusion roller below the mounting seat to move horizontally to push the first carbon fiber strip to the mold table. Then the first motor drives the first threaded screw to rotate, which can effectively drive the mounting seat to move along the Z-axis direction, and the second threaded sleeve drives the extrusion roller to move along the X-axis direction. The electric push rod above the extrusion roller can drive it to move along the Y-axis direction, so that the first carbon fiber strip can be pressed against the outer wall of the mold table through the extrusion roller to form a second carbon fiber strip in the shape of a racket frame. The whole process has a high degree of automation, which also improves the forming rate of the first carbon fiber strip.

[0019] 2. By adopting the above-mentioned rotating shaft, pressing groove and positioning groove, in the process of the molding component driving the extrusion roller to move, the positioning groove and the pressing groove can be used to limit the first carbon fiber strip when it moves, ensuring that one side of the first carbon fiber strip is inserted into the positioning groove, so that the movement of the extrusion roller can drive the movement of the first carbon fiber strip. At the same time, the positioning groove is distributed in a quarter circle on the circumferential outer wall of the extrusion roller. Therefore, when the first carbon fiber strip is subsequently extruded and molded, the rotating shaft at the top of the extrusion roller will drive it to rotate, so that the complete side of the extrusion roller alternately contacts the first carbon fiber strip, thereby realizing uniform extrusion molding of the first carbon fiber strip. At the same time, during the molding process, the height limiting effect of the pressing groove and the positioning groove can avoid the situation where the first carbon fiber strip is deformed too much and causes the height to exceed the standard, so that the molded second carbon fiber strip meets people's molding needs.

[0020] 3. The above-mentioned lifting assembly can realize automatic unloading of the formed second carbon fiber strip, specifically, by starting the third motor, the third motor can drive the third threaded screw to rotate, and the cross bar can be driven to rise as a whole during the rotation of the third threaded screw, and the mold platform located in the lifting groove can be lifted up by the rise of the cross bar, so that the second carbon fiber strip can be quickly separated from the mold platform, and at the same time, the rotating column can be driven to rotate during the rotation of the third threaded screw, and the first bevel gear can be driven to rotate by the rotation of the rotating column, and the second bevel gear can be driven to rotate during the rotation of the first bevel gear, and when the second bevel gear rotates, the second threaded screw can be driven to rotate, and the rotation of the second threaded screw can drive the third guide cylinder at its top to move along the Z-axis direction. During the movement of the third guide cylinder along the Z-axis direction, since a push plate is fixedly connected to its top, the push plate follows the third guide cylinder to move along the Z-axis direction, so that the formed second carbon fiber strip can be effectively pushed out of the pushing groove, thereby completing the unloading of the second carbon fiber strip.

[0028] In summary, the working principle of the first embodiment is as follows: the staff places the first carbon fiber strip 9 on the conveyor belt 8 in sequence, and then starts the conveyor belt 8 to realize automatic conveyance of the first carbon fiber strip 9. When the conveyor belt 8 conveys the first carbon fiber strip 9 to one side of the mold table 10, the first motor 14 and the second motor 15 are started at the same time. The second motor 15 can make the second threaded sleeve 21 drive the squeezing roller 26 under the mounting seat 18 to move horizontally to push the first carbon fiber strip 9 to the mold table 10. Then the first motor 14 drives the first threaded screw 22 to rotate.

The function is to limit the first carbon fiber strip 9 when it moves, ensuring that one side of the first carbon fiber strip 9 is stuck in the positioning groove 2602, so that the movement of the extrusion roller 26 can drive the first carbon fiber strip 9 to move. At the same time, the positioning groove 2602 is distributed in a quarter circle on the circumferential outer wall of the extrusion roller 26. Therefore, when the first carbon fiber strip 9 is subsequently extruded and formed, the top shaft 2603 of the extrusion roller 26 will drive it to rotate, so that the complete side of the extrusion roller 26 is alternately in contact with the first carbon fiber strip 9, thereby achieving uniform extrusion and forming of the first carbon fiber strip 9. During the molding process, the height limiting effect of the pressing groove 2601 and the positioning groove 2602 can avoid the first carbon fiber strip 9 from being over-deformed and causing the height to exceed the standard, so that the molded second carbon fiber strip 11 meets people's molding needs. The third motor 36 can drive the third threaded screw 44 to rotate. During the rotation of the third threaded screw 44, the cross bar 32 can be driven to rise as a whole. The rise of the cross bar 32 can lift the mold platform 10 located in the lifting groove 42, so that the second carbon fiber strip 11 can be quickly separated from the mold platform 10.

The circumferential outer wall of the rod 30 is meshed with a third threaded sleeve 40, the top outer wall of the third threaded sleeve 40 is fixedly connected with a third guide cylinder 41, the interior of the third guide cylinder 41 is plugged with a second guide rod 29, the two ends of the second guide rod 29 are respectively fixedly connected to the outer wall of one side of the vertical plate 39 and the inner wall of one side of the box body 1, the top outer wall of the third guide cylinder 41 is fixedly connected with a push plate 48, the bottom outer wall of the mold table 10 is provided with a storage groove 47, the push plate 48 is located inside the storage groove 47, and the outer wall of one side of the fixed cover 2 is provided with a push groove 13, as shown in FIG. Figure 7-Figure 8 As shown, during the rotation of the third threaded screw 44, the rotating column 12 can be driven to rotate, and the rotation of the rotating column 12 can drive the first bevel gear 37 to rotate. During the rotation of the first bevel gear 37, the second bevel gear 38 can be driven to rotate. When the second bevel gear 38 rotates, the second threaded screw 30 can be driven to rotate. The rotation of the second threaded screw 30 can drive the third guide cylinder 41 at its top to move along the Z-axis direction. During the movement of the third guide cylinder 41 along the Z-axis direction, since the push plate 48 is fixedly connected to the top thereof, the push plate 48 follows the third guide cylinder 41 to move along the Z-axis direction, so that the formed second carbon fiber strip 11 can be effectively pushed out from the push groove 13, thereby completing the unloading of the second carbon fiber strip 11.

[0030] The third implementation method: This embodiment adds the following structure based on the embodiment 1-2, please refer to Figure 11-Figure 12The specific configuration is as follows: a support plate 51 is fixedly connected to the bottom outer wall of the mold platform 10, and an airbag 49 is fixedly connected to the circumferential outer wall of the support plate 51. The specifications of the airbag 49 are adapted to the specifications of the mold platform 10. A pressure sensor 50 is arranged inside the airbag 49. The pressure sensor 50 is electrically connected to the control console 3. When the mold platform 10 is lifted up, the support plate 51 fixed thereunder will also rise together. When the support plate 51 rises to the same horizontal plane as the second carbon fiber strip 11, the circumferential inner wall of the second carbon fiber strip 11 will contact the airbag 49 on the outer wall of the support plate 51. In the process of the airbag 49 contacting and rising with the second carbon fiber strip 11, the airbag 49 contacts with the second carbon fiber strip 11. If the structure of the second carbon fiber strip 11 is uniform, there is no obvious extrusion between the airbag 49 and the second carbon fiber strip 11, and the pressure data of the pressure sensor 50 remains within the standard range. On the contrary, if the data of the pressure sensor 50 increases significantly, it means that the two are squeezed more, or decreases significantly, it means that the two are suddenly out of contact, which can indicate that the structure of the second carbon fiber strip 11 does not meet the standards, thereby realizing the quality inspection of the completed second carbon fiber strip 11.

[0031] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
