[0032] 2) Grinding: Use a file to grind the surface of the brim core plate made in step 1), and repeat the operation three times or more;

[0033] 3) Preparation of the brim: the brim wrapping cloth is cut in advance, and the wrapping cloth is stacked in order near the workbench, and then the brim core plate processed in step 2) is fixed on the workbench by a clamping device, and then a layer of hot melt glue is injected on the surface of the brim core plate by a hot melt glue gun, and then the wrapping cloth is covered on the brim core plate, and pressed by an extrusion roller to realize the compounding of the wrapping cloth and the brim core plate, and then the brim core plate is turned over, and the excess part of the wrapping cloth is bonded to the brim core plate to realize the edging and make the brim;

[0034] 4) Preparation of cap wall: first cut the grey cloth into the specified size, then close the grey cloth into a sleeve shape, connect the closed ends by sewing, and make a cap wall with a diameter gradually decreasing from top to bottom;

[0035] 5) Pre-forming: first place a round cardboard on the model table of the shaping mold, then put the cap wall made in step 4) on the model table and fit it with the round cardboard, then drive the model table to rise so that the edge of the top opening of the cap wall fits with the edge of the round cardboard, and then use a hot melt glue gun to inject a layer of hot melt glue between the two to achieve pre-forming and make a blank;

[0036] 6) Assembly process: Use a hot melt glue gun to inject a layer of hot melt glue on the top of the blank made in step 5), and then place the brim made in step 3) on the top of the blank and press it to make a finished bachelor's cap.

[0037] The present invention adopts a preparation process flow of plate cutting, grinding treatment, brim preparation, hat wall preparation, pre-forming, and assembly processes, and the steps are coherent and orderly, the operation is simple, and the efficiency is high. Among them, through the grinding treatment step, the surface of the brim core plate is repeatedly ground with a file, which greatly improves the roughness of the surface of the brim core plate. When the brim preparation step is performed later, the hot melt adhesive can more easily penetrate the brim core plate, thereby increasing the bonding area of ​​the brim core plate, making the surface of the brim core plate have higher adhesion, thereby greatly improving the bond between the brim core plate and the wrapping cloth. The bonding firmness between the caps is improved, thereby improving the structural firmness of the bachelor's cap. Through the steps of cap wall preparation and pre-forming, a cap wall with a diameter gradually decreasing from top to bottom is first made, and then the cap wall is put on the model table. By driving the model table to rise, the edge of the top opening of the cap wall is fit with the edge of the circular cardboard to achieve the pre-forming of the cap wall. In the assembly process, the brim can be directly bonded to the cap wall for fixation. Since the pre-forming is carried out in advance, the bonding dislocation can be effectively avoided, and the tedious operation of adjustment is eliminated, which greatly improves the preparation efficiency of the bachelor's cap and saves time and effort.

[0038] See also Figure 1 , Figure 2 As shown, the shaping mold includes a shell 1, a model platform 2 and a driving mechanism for driving the model platform 2 to rise and fall are arranged inside the shell 1. When performing the pre-shaping step, a piece of circular cardboard can be placed on the model platform 2 of the shaping mold first, and then the cap wall can be put on the model platform 2. Then, the model platform 2 can be driven to automatically rise by the driving mechanism. The lifting force of the upward movement of the model platform 2 can push the edge of the top opening of the cap wall to automatically fit the edge of the circular cardboard, so as to realize the pre-shaping of the cap wall. The operation is relatively convenient and simple. The driving mechanism includes a cylinder 3, and a lifting platform 5 is connected to the piston rod 4 of the cylinder 3. A positioning groove 11 for embedding the circular cardboard is provided on the top of the model platform 2. By embedding the circular cardboard into the positioning groove 11, the pre-positioning of the circular cardboard can be realized, so that the circular cardboard can be prevented from falling during the rising process of the model platform 2, and the adhesion between the circular cardboard and the cap wall is ensured. The accuracy of the combined position is improved, thereby improving the efficiency of pre-forming, and a connecting rod 6 fixedly connected to the top of the lifting platform 5 is arranged at the bottom of the model platform 2. The piston rod 4 is controlled by the cylinder 3 to be extended and retracted, so that the lifting platform 5 can be driven to rise or fall, so that the model platform 2 can be driven to rise and fall through the connecting rod 6, which is easy to operate and ensures the lifting force on the cap wall. Among them, a partition plate 7 is arranged inside the shell 1, and a plurality of through holes 8 are opened on the partition plate 7, and a plurality of sliding rods 9 penetrating the through holes 8 are arranged at the bottom of the lifting platform 5, and a limiting block 10 is arranged at the bottom of the sliding rod 9. When the lifting platform 5 rises or falls, the sliding rod 9 will slide up and down in the through hole 8 accordingly. The movement direction of the lifting platform 5 can be limited by limiting the sliding rod 9 through the through hole 8, so as to avoid deviation of the lifting platform 5 during movement, thereby improving the smoothness of the lifting of the lifting platform 5.

[0039] See also Figure 2 , Figure 3As shown, a clamping assembly for clamping the cap wall is provided on the outer wall of the shell 1. After the cap wall is put on the model platform 2, the end of the cap wall can be clamped on the outer wall of the shell 1 by the clamping assembly, so that the end of the cap wall can be clamped and positioned, so that the cap wall is not easy to fall off during the process of unfolding with the rise of the lifting platform 5, thereby ensuring the stability of the cap wall during the pre-molding process. The clamping device includes a clamping plate 12, and a clampable space is formed between the clamping plate 12 and the outer wall of the shell 1, and there is a force acting toward each other between the clamping plate 12 and the outer wall of the shell 1, so that the end of the cap wall can be clamped in the clampable space formed between the clamping plate 12 and the outer wall of the shell 1, and when the cap wall needs to be disassembled, it only needs to adjust the clamping plate 12 to make it away from the outer wall of the shell 1, so that the clamping of the cap wall can be released, and the operation is relatively simple. For convenience, the splint 12 is fixedly connected to the outer wall of the shell 1 by an arc segment 13. The arc segment 13 is elastic. When the splint 12 is adjusted to move away from the outer wall of the shell 1, the arc segment 13 will undergo elastic deformation. When the splint 12 is released, the arc segment 13 will automatically rebound and restore its original shape after being freed from the tension, thereby driving the splint 12 to rebound and achieve clamping. A pinching piece 14 is provided at one end of the splint 12 away from the arc segment 13. When adjusting the position of the splint 12, the pinching piece 14 can be pinched to apply force, and the pinching piece 14 can be used as a force application point, thereby making the operation of adjusting the splint 12 easier and more labor-saving. Among them, the splint 12, the arc segment 13 and the pinching piece 14 are all made of stainless steel, which has high strength and hardness and is not easy to rust, so that the clamping assembly has good durability.
