[0002] Carbon fiber is a new fiber material with high strength and high modulus fibers with a carbon content of more than 95%. Those with a carbon content higher than 99% are called graphite fibers. It is composed of flaky graphite microcrystals and other organic fibers stacked along the fiber axial direction, and is obtained by carbonization and graphitization treatment to obtain microcrystalline graphite materials. Carbon fiber has many excellent properties. The axial strength and modulus of carbon fiber are high, the density is low, the specific performance is high, there is no creep, it is resistant to ultra-high temperature in a non-oxidizing environment, has good fatigue resistance, the specific heat and conductivity are between non-metals and metals, the thermal expansion coefficient is small and has anisotropy, has good corrosion resistance, and has good X-ray permeability. It has good electrical and thermal conductivity, good electromagnetic shielding performance, etc. And carbon fiber badminton rackets are one of the application fields of carbon fiber materials.

[0003] At present, the preforming of carbon fiber badminton rackets is carried out by manually heating and pressurizing through a forming die for preforming. The work efficiency is low, the forming size is inconsistent, and it is difficult to ensure the normal progress of the forming process of carbon fiber badminton rackets.

[0005] Based on the above retrieval, combined with the existing technology, it is found that when the existing carbon fiber badminton rackets are preformed, the staff needs to manually place the carbon fiber strips on the preforming template, resulting in low preforming efficiency of the subsequent carbon fiber badminton rackets, and the entire preforming process can only make the racket form a semi-circular arc, and cannot form a complete badminton racket frame, which cannot meet the preforming requirements of people 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

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that when preforming an existing carbon fiber badminton racket, workers need to manually place carbon fiber strips on a preforming template, resulting in low preforming efficiency of the subsequent carbon fiber badminton racket. Moreover, only a semi-circular shape can be formed for the racket during the entire preforming process, and a complete badminton racket frame cannot be formed, which cannot meet the preforming requirements of people for badminton rackets.

[0007] To solve the above problems, the present invention provides a preforming device for the production of carbon fiber badminton rackets, including:

[0008] A box body;

[0009] A support, the support is fixedly connected to the outer wall of the bottom of the box body, the top outer wall of the box body is fixedly connected with a top plate, through grooves are opened on the tops of the box body and the top plate, and a conveyor belt is arranged inside the through grooves;

[0010] The 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;

[0011] A control console, the control console is fixedly connected to the outer wall of one side of the box body, and the top outer wall of the top plate is fixedly connected with a fixed cover;

[0012] A mold table, the mold table is arranged above the top plate, a second carbon fiber strip is wound around the outer wall of the mold table, and the first carbon fiber strip and the second carbon fiber strip have the same specifications;

[0013] A forming assembly for winding the second carbon fiber strip;

[0014] A lifting assembly.

[0015] In the above, the forming assembly includes a pressing roller arranged above the top plate, a positioning groove is opened on the circumferential outer wall of the pressing roller, the cross-section of the positioning groove is in the shape of a right trapezoid, the positioning groove is distributed in a quarter circle on the circumferential outer wall of the pressing roller, and a pressing groove is opened on one side of the positioning groove, and the pressing groove is communicated with the positioning groove.

[0016] As a further supplement to the present application, during the process of the forming assembly driving the extrusion roller to move, the combined action of the positioning groove and the pressing groove can limit the movement of the first carbon fiber strip when it moves, ensuring that one side of the first carbon fiber strip is caught in 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 grooves are distributed in a quarter-circle shape on the circumferential outer wall of the extrusion roller. Therefore, when the first carbon fiber strip is subsequently extruded and formed, the top rotating shaft of the extrusion roller will drive its rotation, enabling the complete side of the extrusion roller to alternately contact the first carbon fiber strip, achieving uniform extrusion and forming of the first carbon fiber strip. At the same time, during the forming process, through the limiting effect of the height of the pressing groove and the positioning groove, it is possible to avoid the situation where the first carbon fiber strip is deformed too much and the height exceeds the standard, making the formed second carbon fiber strip meet the forming requirements of people.

[0017] As another improvement of the present application, a first motor is fixedly connected to the outer wall of one side of the fixed cover. The output end of the first motor is fixedly connected to a first threaded lead screw. A first threaded sleeve is engaged with the circumferential outer wall of the first threaded lead screw. A reinforcing frame is fixedly connected to one side of the first threaded sleeve. The bottom of the reinforcing frame is fixedly connected to a mounting seat. First guide rods are fixedly connected to the inner walls of both sides of the fixed cover. First guide cylinders are sleeved on the circumferential outer walls of the first guide rods. The first guide cylinders are fixedly connected to the mounting seat through the other reinforcing frame. Partition plates are fixedly connected to the inner walls of both sides of the mounting seat. A second motor is fixedly connected to the outer wall of one side of the mounting seat. The output end of the second motor is fixedly connected to a fourth threaded lead screw. A second threaded sleeve is engaged with the circumferential outer wall of the fourth threaded lead screw. A vertical frame is fixedly connected to the bottom of the second threaded sleeve. A limiting groove is formed in the outer wall of the top of the partition plate. One end of the vertical frame passes through the inside of the limiting groove. A horizontal plate is fixedly connected to the bottom of the vertical frame. An electric push rod is fixedly connected to the outer wall of the bottom of the horizontal plate. The output end of the electric push rod is fixedly connected to a circular plate. A rotating shaft is fixedly connected to the bottom of the circular plate. The rotating shaft is rotatably connected to the outer wall of the top of the extrusion roller.

[0018] As a further improvement supplement of 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 the 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 simultaneously. Through the second motor, the second threaded sleeve can 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, while the second threaded sleeve drives the extrusion roller to move along the X-axis direction, and the electric push rod above the extrusion roller can drive it to move along the Y-axis direction. Thus, the first carbon fiber strip can be closely attached to the outer wall of the mold table by 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, and thus also improves the forming rate of the first carbon fiber strip.

[0019] As a further 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 with a third threaded screw. A fourth threaded sleeve is meshed with the circumferential outer wall of the third threaded screw. One outer wall of the fourth threaded sleeve is fixedly connected with a cross bar. The inner walls of both sides of the box body are respectively fixedly connected with a first shell and a second shell. The fourth threaded sleeve is located inside the second shell. Both outer walls of the cross bar are fixedly connected with inclined bars. One end of the inclined bar is fixedly connected to the outer wall of the bottom of the mold table. A lifting groove is opened on the outer wall of the top of the box body, and the lifting groove is adapted to the mold table. Both inner walls of the first shell are fixedly connected with third guide rods. A second guide cylinder is sleeved on the circumferential outer wall of the third guide rod. One end of the cross bar away from the fourth threaded sleeve is fixedly connected to one outer wall of the second guide cylinder.

[0020] As a further improvement supplement of the present application, the third motor can drive the third threaded screw to rotate. During the rotation of the third threaded screw, the cross bar can be driven to rise as a whole. By rising the cross bar, the mold table located in the lifting groove can be jacked up, so that the second carbon fiber strip can be quickly separated from the mold table.

[0021] As yet another improvement of the present application, a rotating column is fixedly connected to the outer wall of the top of the third threaded lead screw. A first bevel gear is fixedly connected to the circumferential outer wall of the rotating column. The first bevel gear meshes with a second bevel gear. A vertical plate is fixedly connected to the outer wall of the top of the second housing. A second threaded lead screw is rotatably and fixedly connected to the outer wall of one side of the vertical plate. One end of the second threaded lead screw is fixedly connected to the outer wall of one side of the second bevel gear. A third threaded sleeve is meshed with the circumferential outer wall of the second threaded lead screw. A third guiding cylinder is fixedly connected to the outer wall of the top of the third threaded sleeve. A second guiding rod is inserted into the interior of the third guiding cylinder. Two ends of the second guiding rod are respectively fixedly connected to the outer wall of one side of the vertical plate and the inner wall of one side of the box body. A pushing plate is fixedly connected to the outer wall of the top of the third guiding cylinder. A receiving groove is formed in the outer wall of the bottom of the mold table. The pushing plate is located inside the receiving groove. A material pushing groove is formed in the outer wall of one side of the fixed cover.

[0022] As a supplement to yet another improvement of the present application, during the rotation of the third threaded lead screw, it can drive the rotation of the rotating column. Through the rotation of the rotating column, the first bevel gear can be driven 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 lead screw can be driven to rotate. Through the rotation of the second threaded lead screw, the third guiding cylinder at its top can be driven to move along the Z-axis direction. During the movement of the third guiding cylinder along the Z-axis direction, since a pushing plate is fixedly connected to its top, the pushing plate can thus follow the third guiding cylinder to move along the Z-axis direction, and can effectively push the formed second carbon fiber strip out of the material pushing groove, completing the unloading work of the second carbon fiber strip.

[0023] As yet another improvement of the present application, a support plate is fixedly connected to the outer wall of the bottom of the mold table. An airbag is fixedly connected to the circumferential outer wall of the support plate. The specification of the airbag is adapted to the specification of the mold table. A pressure sensor is arranged inside the airbag. The pressure sensor is electrically connected to the control console.

[0024] As a supplement to yet another improvement of the present application, when the mold table is lifted, the support plate fixed below it will also rise simultaneously. 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 come into contact with the airbag on the outer wall of the support plate. During the upward movement of the airbag in contact with the second carbon fiber strip, if the second carbon fiber strip has a uniform structure, there will be no obvious extrusion between the airbag and the second carbon fiber strip, and when the pressure data of the pressure sensor remains within the standard range. On the contrary, if the data of the pressure sensor increases significantly, it indicates that there is a large extrusion between the two, or if it decreases significantly, it indicates that there is suddenly no contact between the two, both of which can illustrate that the structure of the second carbon fiber strip does not meet the standard, realizing the quality inspection of the completed second carbon fiber strip.

[0025] In summary, after adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0026] 1. By adopting the above conveyor belt and forming assembly, automatic pre-forming of carbon fiber badminton rackets can be achieved, and the entire forming process does not require manual intervention, effectively improving the forming efficiency of carbon fiber badminton rackets. Specifically, the staff sequentially places the first carbon fiber strips on the conveyor belt, and then starts the conveyor belt to automatically convey the first carbon fiber strips. When the conveyor belt conveys the first carbon fiber strips to one side of the mold table, the first motor and the second motor are started simultaneously. The second motor enables the second threaded sleeve to drive the extrusion roller under the mounting seat to move horizontally and push the first carbon fiber strips to the mold table. Subsequently, the first motor drives the first threaded lead screw to rotate, which can effectively drive the mounting seat to move along the Z-axis direction, while the second threaded sleeve drives the extrusion roller to move along the X-axis direction, and the electric push rod above the extrusion roller can drive it to move along the Y-axis direction. Thus, the first carbon fiber strips can be tightly attached to the outer wall of the mold table by the extrusion roller to form the second carbon fiber strips in the shape of a racket frame. The entire process has a high degree of automation, and thus also improves the forming rate of the first carbon fiber strips.

[0027] 2. By adopting the above rotating shaft, pressing groove and positioning groove, during the process of the forming assembly driving the extrusion roller to move, through the combined action of the positioning groove and the pressing groove, the first carbon fiber strips can be limited during movement, ensuring that one side of the first carbon fiber strips is stuck in the positioning groove, so that the extrusion roller can drive the first carbon fiber strips to move. At the same time, the positioning grooves are distributed in a quarter-circle shape on the circumferential outer wall of the extrusion roller. Therefore, when the first carbon fiber strips are subsequently extruded and formed, the rotating shaft at the top of the extrusion roller will drive it to rotate, enabling the complete side of the extrusion roller to alternately contact the first carbon fiber strips, achieving uniform extrusion and forming of the first carbon fiber strips. At the same time, during the forming process, through the limiting effect of the height of the pressing groove and the positioning groove, the situation where the first carbon fiber strips are deformed too much and the height exceeds the standard can be avoided, so that the formed second carbon fiber strips meet the forming requirements of people.

[0028] 3. By adopting the above-mentioned lifting component, automatic unloading of the formed second carbon fiber strip can be achieved. Specifically, by starting the third motor, the third motor can drive the third threaded screw rod to rotate. During the rotation of the third threaded screw rod, the cross bar can be driven to rise as a whole. By the rising of the cross bar, the mold table located in the lifting groove can be jacked up, so that the second carbon fiber strip can be quickly separated from the mold table. At the same time, during the rotation of the third threaded screw rod, the rotating column can be driven to rotate. By the rotation of the rotating column, the first bevel gear can be driven 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 rod can be driven to rotate. By the rotation of the second threaded screw rod, the third guide cylinder at its top can be driven 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 can follow the third guide cylinder to move along the Z-axis direction, and the formed second carbon fiber strip can be effectively pushed out from the pushing groove, completing the unloading work of the second carbon fiber strip.

[0043] The following will describe in detail two embodiments of the present application with reference to the accompanying drawings.

[0044] The first embodiment:

[0045] The present invention provides a preforming device for the production of carbon fiber badminton rackets. Please refer to Figures 1-10 , including:

[0046] Box body 1;

[0047] Bracket 4, which is fixedly connected to the outer wall of the bottom of the box body 1. The outer wall of the top of the box body 1 is fixedly connected with a top plate 7. Through grooves 6 are opened on the tops of both the box body 1 and the top plate 7, and a conveyor belt 8 is arranged inside the through grooves 6;

[0048] The first carbon fiber strip 9 is evenly distributed on the top of the conveyor belt 8. The outer wall of the top of the top plate 7 is fixedly connected with a guard plate 5. The number of the guard plates 5 is two groups, and the two groups of guard plates 5 are respectively arranged on both sides of the conveyor belt 8;

[0049] The control console 3 is fixedly connected to the outer wall of one side of the box body 1. The outer wall of the top of the top plate 7 is fixedly connected with a fixed cover 2;

[0050] The mold table 10 is arranged above the top plate 7. The outer wall of the mold table 10 is wound with a second carbon fiber strip 11. The first carbon fiber strip 9 and the second carbon fiber strip 11 have the same specifications;

[0051] A forming assembly for winding the second carbon fiber strip 11;

[0052] A lifting assembly, as Figures 1-2 shown, can realize the automatic preforming of the carbon fiber badminton racket, and the whole forming process does not require manual intervention, effectively improving the forming efficiency of the carbon fiber badminton racket.

[0053] In the present invention, the forming assembly includes an extrusion roller 26 arranged above the top plate 7. The circumferential outer wall of the extrusion roller 26 is provided with a positioning groove 2602. The cross-section of the positioning groove 2602 is in the shape of a right trapezoid. The positioning groove 2602 is distributed in a quarter circle on the circumferential outer wall of the extrusion roller 26. A pressing groove 2601 is opened on one side of the positioning groove 2602. The pressing groove 2601 is communicated with the positioning groove 2602. As Figure 9 shown, during the forming process, due to the limiting effect of the heights of the pressing groove 2601 and the positioning groove 2602, the situation that the first carbon fiber strip 9 deforms too much and causes the height to exceed the standard can be avoided, so that the formed second carbon fiber strip 11 meets the forming requirements of people.

[0054] In the present invention, a first motor 14 is fixedly connected to the outer wall of one side of the fixed cover 2. The output end of the first motor 14 is fixedly connected to a first threaded lead screw 22. A first threaded sleeve 16 is engaged with the circumferential outer wall of the first threaded lead screw 22. One side of the first threaded sleeve 16 is fixedly connected to a reinforcing frame 17. The bottom of the reinforcing frame 17 is fixedly connected to a mounting seat 18. First guide rods 28 are fixedly connected to both inner walls of the fixed cover 2. First guide cylinders 27 are sleeved on the circumferential outer walls of the first guide rods 28. The first guide cylinders 27 are fixedly connected to the mounting seat 18 through another reinforcing frame 17. Partition plates 19 are fixedly connected to both inner walls of the mounting seat 18. A second motor 15 is fixedly connected to the outer wall of one side of the mounting seat 18. The output end of the second motor 15 is fixedly connected to a fourth threaded lead screw. A second threaded sleeve 21 is engaged with the circumferential outer wall of the fourth threaded lead screw. The bottom of the second threaded sleeve 21 is fixedly connected to a vertical frame. A limiting groove 20 is formed in the top outer wall of the partition plate 19. One end of the vertical frame passes through the inside of the limiting groove 20. The bottom of the vertical frame is fixedly connected to a cross plate 23. An electric push rod 24 is fixedly connected to the bottom outer wall of the cross plate 23. The output end of the electric push rod 24 is fixedly connected to a circular plate 25. A rotating shaft 2603 is fixedly connected to the bottom of the circular plate 25. The rotating shaft 2603 is rotatably connected to the top outer wall of the extrusion roller 26. As Figures 3-4 shown, 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 simultaneously. Through the second motor 15, the second threaded sleeve 21 can drive the extrusion roller 26 below the mounting seat 18 to move horizontally to push the first carbon fiber strip 9 to the mold table 10. Subsequently, the first motor 14 drives the first threaded lead screw 22 to rotate, which can effectively drive the mounting seat 18 to move along the Z-axis direction, while the second threaded sleeve 21 drives the extrusion roller 26 to move along the X-axis direction. The electric push rod 24 above the extrusion roller 26 can drive it to move along the Y-axis direction, so that the first carbon fiber strip 9 can be closely attached to the outer wall of the mold table 10 by the extrusion roller 26 to form a second carbon fiber strip 11 in the shape of a racket frame. The whole process has a high degree of automation, and thus also improves the forming rate of the first carbon fiber strip 9. During the process of the forming assembly driving the extrusion roller 26 to move, through the combined action of the positioning groove 2602 and the pressing groove 2601, the first carbon fiber strip 9 can be limited during movement, ensuring that one side of the first carbon fiber strip 9 is clamped into the positioning groove 2602, so that the movement of the extrusion roller 26 can drive the movement of the first carbon fiber strip 9. 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 rotating shaft 2603 at the top of the extrusion roller 26 will drive it to rotate, so that the complete side of the extrusion roller 26 alternately contacts the first carbon fiber strip 9, realizing the uniform extrusion and forming of the first carbon fiber strip 9.

[0055] In the present invention, the lifting assembly includes a third motor 36 fixedly connected to the inner wall of the bottom of the box body 1. The output end of the third motor 36 is fixedly connected to a third threaded lead screw 44. A fourth threaded sleeve 45 is engaged with the circumferential outer wall of the third threaded lead screw 44. One side outer wall of the fourth threaded sleeve 45 is fixedly connected to a cross bar 32. First shells 31 and second shells 35 are respectively fixedly connected to the two inner walls of the box body 1. The fourth threaded sleeve 45 is located inside the second shell 35. Oblique rods 34 are fixedly connected to both outer walls of the cross bar 32. One end of the oblique rod 34 is fixedly connected to the outer wall of the bottom of the mold table 10. A lifting groove 42 is formed in the outer wall of the top of the box body 1. The lifting groove 42 is adapted to the mold table 10. Third guide rods 43 are fixedly connected to both inner walls of the first shell 31. Second guide cylinders 33 are sleeved on the circumferential outer walls of the third guide rods 43. One end of the cross bar 32 away from the fourth threaded sleeve 45 is fixedly connected to one side outer wall of the second guide cylinder 33. As Figure 6 shown, the third motor 36 can drive the third threaded lead screw 44 to rotate. During the rotation of the third threaded lead screw 44, the cross bar 32 as a whole can be driven to rise. By the rising of the cross bar 32, the mold table 10 located in the lifting groove 42 can be jacked up, so that the rapid detachment of the second carbon fiber strip 11 from the mold table 10 can be realized.

[0056] In summary, the working principle of the first implementation method 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 the 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 simultaneously. Through the second motor 15, the second threaded sleeve 21 can drive the extrusion roller 26 below the mounting seat 18 to move horizontally to push the first carbon fiber strip 9 to the mold table 10. Subsequently, the first motor 14 drives the first threaded lead screw 22 to rotate, which can effectively drive the mounting seat 18 to move along the Z-axis direction, while the second threaded sleeve 21 drives the extrusion roller 26 to move along the X-axis direction. The electric push rod 24 above the extrusion roller 26 can drive it to move along the Y-axis direction. Thus, the first carbon fiber strip 9 can be closely attached to the outer wall of the mold table 10 by the extrusion roller 26 to form a second carbon fiber strip 11 in the shape of a racket frame. The automation degree of the whole process is high, and furthermore, the forming rate of the first carbon fiber strip 9 is improved. During the process of the forming assembly driving the extrusion roller 26 to move, through the combined action of the positioning groove 2602 and the pressing groove 2601, the first carbon fiber strip 9 can be limited during movement, ensuring that one side of the first carbon fiber strip 9 is caught in the positioning groove 2602, so that 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 shape 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 rotating shaft 2603 of the extrusion roller 26 will drive it to rotate, enabling the complete side of the extrusion roller 26 to alternately contact the first carbon fiber strip 9, realizing the uniform extrusion and forming of the first carbon fiber strip 9. At the same time, during the forming process, through the limiting effect of the heights of the pressing groove 2601 and the positioning groove 2602, the situation that the first carbon fiber strip 9 deforms too much and causes the height to exceed the standard can be avoided, making the formed second carbon fiber strip 11 meet the forming requirements of people. Through the third motor 36, the third threaded lead screw 44 can be driven to rotate. During the rotation of the third threaded lead screw 44, the whole cross bar 32 can be driven to rise, and by the rising of the cross bar 32, the mold table 10 located in the lifting groove 42 can be lifted, thus realizing the rapid separation of the second carbon fiber strip 11 from the mold table 10.

[0057] The second implementation method:

[0058] On the basis of Embodiment 1, the following structure is added in this embodiment, and the specific setting is as follows: A rotating column 12 is fixedly connected to the outer wall of the top of the third threaded lead screw 44. A first bevel gear 37 is fixedly connected to the outer wall of the circumference of the rotating column 12. The first bevel gear 37 meshes with a second bevel gear 38. A vertical plate 39 is fixedly connected to the outer wall of the top of the second housing 35. A second threaded lead screw 30 is rotatably and fixedly connected to the outer wall of one side of the vertical plate 39. One end of the second threaded lead screw 30 is fixedly connected to the outer wall of one side of the second bevel gear 38. A third threaded sleeve 40 meshes with the outer wall of the circumference of the second threaded lead screw 30. A third guide cylinder 41 is fixedly connected to the outer wall of the top of the third threaded sleeve 40. A second guide rod 29 is inserted into the inside of the third guide cylinder 41. 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. A push plate 48 is fixedly connected to the outer wall of the top of the third guide cylinder 41. A storage groove 47 is formed in the outer wall of the bottom of the mold table 10. The push plate 48 is located inside the storage groove 47. A material pushing groove 13 is formed in the outer wall of one side of the fixed cover 2. As Figures 7-8 shown, during the rotation of the third threaded lead screw 44, the rotating column 12 can be driven to rotate. By the rotation of the rotating column 12, the first bevel gear 37 can be driven 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 lead screw 30 can be driven to rotate. By the rotation of the second threaded lead screw 30, the third guide cylinder 41 at its top can be driven 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 its top, the push plate 48 can follow the third guide cylinder 41 to move along the Z-axis direction, and the formed second carbon fiber strip 11 can be effectively pushed out from the material pushing groove 13, completing the unloading work of the second carbon fiber strip 11.

[0059] The 3rd embodiment:

[0060] On the basis of Embodiments 1-2, the following structure is added. Please refer to Figures 11-12, the specific settings are as follows: A support plate 51 is fixedly connected to the bottom outer wall of the mold table 10, an airbag 49 is fixedly connected to the circumferential outer wall of the support plate 51, the specification of the airbag 49 is adapted to the specification of the mold table 10, a pressure sensor 50 is arranged inside the airbag 49, and the pressure sensor 50 is electrically connected to the control console 3. When the mold table 10 is lifted, the support plate 51 fixed below it 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. During the process of the airbag 49 rising in contact with the second carbon fiber strip 11, if the second carbon fiber strip 11 has a uniform structure, there will be no obvious extrusion between the airbag 49 and the second carbon fiber strip 11, and when 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 there is a large extrusion between the two, or if it decreases significantly, it means that there is suddenly no contact between the two, both of which can indicate that the structure of the second carbon fiber strip 11 does not meet the standard, realizing the quality inspection of the completed second carbon fiber strip 11.

[0061] Combined with the current actual requirements, the above-mentioned implementation method adopted in this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
