DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the present invention. Example

[0027] A bachelor's cap preparation process comprises the following steps: S1. Drawing design: Determine the design framework and draw the design drawings according to the specifications of the bachelor's cap. The drawings are required to include the overall shape, size, tassel style and position of the bachelor's cap; Through precise design drawings, we ensure that all parts of the bachelor's cap (such as the top, body, strap, and tassel) meet the design specifications and functional requirements, avoid errors in the subsequent production process, and improve production accuracy and efficiency.

[0028] S2. Raw material preparation: prepare hat body fabric, cardboard, elastic fabric, lining fabric and tassels according to the drawing requirements; S3, fabric cutting: the hat body fabric is cut into squares and strips by a cutting machine for making the hat top and the hat body respectively, and the lining fabric is cut into strips matching the hat body fabric for the lining; the elastic fabric is cut into strips matching the strips for the hat band; Through precise cutting, the size of each component is ensured to be accurate, reducing the processing difficulties or waste caused by size mismatch in subsequent processes. In particular, the precise cutting of the chin strap and lining fabric lays the foundation for the subsequent chin strap installation.

[0029] S4, production of square plate for hat top: Cut the cardboard into square plates, and then wrap and sew the square fabric cut in S3 to obtain the square plate for hat top: Through the above process, the flatness and strength of the square plate on the top of the hat are ensured, and at the same time, the appearance and touch of the top of the hat are enhanced by wrapping with fabric, providing support for the appearance and structure of the hat.

[0030] S5, sewing the cap body: after overlapping and sewing one strip of fabric and at least four lining fabrics, winding them into a tube and sewing them to obtain a cylindrical cap body with a lining inside, during this process, the hat band prepared in S3 will first be fixedly sewn on the cap body and located between the lining and the cap body; The specific operation steps of S5 are as follows: A1. First, prepare a strip of fabric for the hat body, at least 4 lining fabrics of the same size as the strip of fabric for the lining, and a hat band; A2. Align and overlap the four lining fabrics and sew them together, then sew the overlapping lining fabrics to the inner side of the hat body. At the same time, only the upper edge of the lining fabric is fixed to one side of the strip fabric, and a gap is formed between the two for placing the hat strap. Through the above process, the problem of chin strap installation is solved. The chin strap is fixed in the reserved space between the lining and the cap body, without the need for additional hole drilling and sewing, which simplifies the installation process and improves production efficiency.

[0031] A3. After stuffing the hatband into the gap between the lining fabric and the strip fabric, fix the two ends of the hatband to the strip fabric, and finally let the lining fabric cover the top of the hatband, and then sew the lower edge of the lining fabric to the strip fabric.

[0032] Through the above process, the installation of the hatband is easier, which not only ensures the stability and tightness adjustment function of the hatband, but also avoids leaving stitching marks on the surface of the hat body, thereby improving the aesthetics of the bachelor's cap.

[0033] S6, fixing the square plate on the top of the hat in S4 to the top of the hat body by sewing to complete the connection between the square plate on the top of the hat and the hat body, and then fixing the washing label on the inner side of the hat body; The solid connection between the top and the body of the hat ensures the overall structural strength and stability of the hat. The care label is located inside the hat body, which does not affect the appearance and ensures the standard identification and instructions during use.

[0034] S7, tassel installation: fix the tassel prepared in S2 on the square plate on the top of the hat connected to the hat body in S6 to complete the fixing of the tassel to obtain the bachelor's hat; The installation of the tassels meets the position requirements in the design drawings, ensuring the iconic appearance of the bachelor's cap. The tassels are firmly fixed, beautiful and not easy to fall off.

[0035] S8, finished product inspection and packaging and storage: Use automated testing equipment to inspect the bachelor's caps in S8, and package and store those that pass the inspection.

[0036] Automated testing improves the inspection efficiency of finished products, ensures that the quality of each bachelor's cap meets the standards, standardizes the packaging and storage processes, and ensures the quality stability of bachelor's caps before leaving the factory.

[0037] The gap between the upper edge of the lining fabric and the seam line of the strip fabric is 1 cm, and the gap between the lower edge of the lining fabric and the seam line of the strip fabric is 0.8 cm.

[0038] Through strict control of the seam gap, the overall stability and consistency of the cap body are guaranteed, ensuring the fineness and beauty of the seams.

[0039] The care label is located on the side of the hat body away from the lining fabric and is 5 cm away from the lower edge of the lining fabric. The reasonable position design of the care label does not affect the wearing comfort of the hat, but also ensures the integrity of the label, which meets the production standards and usage requirements. Example

[0040] like Figure 1-8As shown, this embodiment discloses a cutting machine, including a frame 1, a work surface 2 connected to a control system on the frame 1, a laser cutting component 3 located above the work surface 2 and a fabric clamping and tensioning component 4 located on both sides of the work surface 2 are slidably arranged on the frame 1, the cutting component and the fabric clamping and tensioning component 4 are connected to a driving mechanism connected to the control system, wherein the control system includes an electric control box and a terminal connected to the electric control box, the electric control box is provided with electrical components such as a PLC circuit board, and the terminal can be a computer, by importing the design drawings into the computer, the control system can allow the laser cutting component 3 to move on the work surface 2 through the driving mechanism, thereby realizing the cutting of the cloth.

[0041] Among them Figure 1-2 As shown in , 8, the laser cutting assembly 3 and the driving mechanism connected thereto are both prior arts, and the improvement of this embodiment mainly lies in the fabric clamping and tensioning assembly 4, so no further elaboration will be made in this embodiment.

[0042] In the existing laser cutting machine, the flatness of the cloth is generally ensured by the adsorption device at the bottom of the work table 2, and the cloth needs to be manually unfolded and arranged, which is very troublesome to operate; in this embodiment, Adding fabric clamping and tensioning components 4 on both sides of the work surface 2 can clamp both sides of the fabric while driving the fabric to move to both sides so that the fabric is in a taut state, making the operation more convenient and quick.

[0043] like Figure 1-3 As shown, the fabric clamping and tensioning assembly 4 includes a mounting frame 41 which is slidably arranged on the frame 1 and located on both sides of the work surface 2. A rotating shaft 42 is rotatably arranged in the mounting frame 41, and one end of the rotating shaft 42 is connected to a driving motor 43. A clamping member 44 which can rotate relatively with the mounting frame 41 is fixedly connected to the rotating shaft 42. The clamping member 44 is used to clamp the two sides of the fabric and can be rotated away from the work surface 2 under the action of the driving motor 43 to pull and tension the fabric to both sides; it also includes a detection assembly 45 which is horizontally arranged on the mounting frame 41 and corresponds to the position of the clamping member 44. The detection assembly 45 is electrically connected to the driving motor 43 through a control system and is used to detect whether the fabric is in a taut state.

[0044] Among them, Figure 3As shown, the mounting frame 41 is slidably arranged on the frame 1 through a pair of rotating motors 47 and a screw 46. The rotating motor 47 can be driven by the control system to rotate to drive the screw 46 to rotate. The rotation of the screw 46 will drive the mounting frame 41 threadedly connected thereto to slide up and down, thereby achieving height adjustment; and a rotating shaft 42 is rotatably connected inside the mounting frame 41, and a clamping member 44 is connected to the rotating shaft 42. The clamping member 44 can clamp both sides of the cloth, thereby achieving the fixing of the cloth position. When the cloth is detected to be uneven by the detection component 45 connected to the control system, the control system will control the driving motor 43 to rotate, and the driving motor 43 will drive the rotating shaft 42 to rotate outward. Since both sides of the cloth are clamped on the rotating shaft 42 by the clamping member 44, when the rotating shaft 42 rotates, both sides of the cloth will be rolled up by the rotating shaft 42 to achieve tensioning.

[0045] The detection component 45 is a photoelectric sensor disposed on the mounting frame 41 and located below the rotating shaft 42. Figure 4 As shown, the photoelectric sensors are arranged diagonally so as to detect a wider range of fabrics; and the photoelectric sensors monitor the displacement or looseness of fabrics by emitting and receiving light beams. If the fabric is loose or wrinkled, the path of the light beam will be disturbed, the sensor will detect the change in light, and feed back the signal to the control system, triggering the drive motor 43 to move until the fabric is flat.

[0046] like Figure 4 As shown, the clamping member 44 includes a clamping cylinder 441 rotatably disposed on the rotating shaft 42, a clamping plate 442 is rotatably connected to the outer circumference of the clamping cylinder 441, a coil spring 443 is disposed between the clamping plate 442 and the clamping cylinder 441, and the coil spring 443 is used to drive the clamping plate 442 to abut against the surface of the clamping cylinder 441.

[0047] The elastic force of the coil spring 443 keeps the clamping plate 442 always close to the surface of the clamping cylinder 441. The rotation of the clamping cylinder 441 drives the clamping plate 442 to clamp the edge of the cloth, and through the cooperation of the roller 7 and the pressing groove 8, the damage to the surface of the cloth is reduced to ensure stable clamping. The rotation of the rotating shaft 42 enables the clamping member 44 to tighten the cloth to both sides at the same time. In order to further reduce the damage to the cloth, a rubber pad can be added to the surface of the clamping plate 442. The rubber pad can increase the friction between the rubber pad and the cloth and reduce the damage to the cloth.

[0048] like Figure 4-5As shown, the clamping plate 442 includes a connecting ring 4421 rotatably connected to both ends of the clamping cylinder 441, and the connecting ring 4421 is extended to the side away from the work table 2 to be provided with a connecting portion 4422 that fits the surface of the clamping cylinder 441, the connecting portion 4422 is arc-shaped, and the end away from the connecting ring 4421 is provided with a clamping portion 4423 tangent to the surface of the clamping cylinder 441, and the clamping portion 4423 tangent to the clamping cylinder 441 can ensure that the cloth is always tangent to the surface of the clamping cylinder 441, thereby ensuring that the cloth will not bend and is always in a horizontal state.

[0049] like Figure 1 , 5 As shown, a feed roller group 6 and a waste winding roller group 5 are arranged at the front and rear ends of the frame 1. The cloth can be placed on the feed roller. During processing, the user passes one end of the cloth through the fabric clamping and tensioning component 4 and the laser cutting component 3, and finally connects it to the waste winding roller group 5. After the laser cutting component 3 completes processing of a section of cloth, the waste winding roller group 5 will wind up the waste. During the waste winding process, the cloth on the feed roller group 6 will be driven to move forward and re-laid on the work surface 2, thereby realizing continuous processing and improving efficiency; and the winding length of the waste winding roller group 5 can be adjusted and controlled by the terminal according to the length of the cloth being processed each time, thereby realizing automatic laying of the cloth.

[0050] And as Figure 4-6 As shown, a plurality of rollers 7 are rotatably provided on one side of the clamping portion 4423 relative to the clamping cylinder 441, the rollers 7 rotate along the length direction of the clamping cylinder 441 and a pressing groove 8 is provided on the surface of the clamping cylinder 441 for abutting and cooperating with the rollers 7, and the roller 7 rotates along the length direction of the rotating shaft 42. Through the cooperation between the rollers 7 and the pressing grooves 8, the friction force of the cloth relative to the work surface 2 can be increased after the cloth is clamped, so that the clamping member 44 can tighten the cloth more smoothly; and when the cloth is processed, when the waste winding roller group 5 drives the cloth to move along the length direction of the rotating shaft 42, the setting of the rollers 7 can make the cloth move more smoothly, avoid the cloth from being damaged due to the friction force of the clamping member 44 on it, and ensure the integrity of the cloth.

[0051] During the waste material winding process, the clamping member 44 will be reset first, and after the fabric is completely laid, the rear fabric will be tensioned and wound again.

[0052] like Figure 7 As shown, a plurality of rotating shafts 42 and clamping members 44 are provided, which are spaced apart along the height direction of the mounting frame 41; each rotating shaft 42 is connected to a driving motor 43, and a sensing member 9 corresponding to the position of each clamping member 44 is provided on the mounting frame 41, and a proximity switch 10 electrically connected to the driving motor 43 through a control system is provided on one side of the work surface 2.

[0053] A plurality of groups of rotating shafts 42 and clamping members 44 distributed along the height direction of the mounting frame 41 can simultaneously cut multiple layers of fabrics to improve production efficiency; and the plurality of clamping members 44 arranged at intervals allow gaps to exist between adjacent fabrics, so that when the laser cutting component 3 cuts the fabric, the fabric will not adhere to and fuse with adjacent fabrics after melting due to the high temperature of the laser, thereby avoiding damage to the fabric; at the same time, a sensing member 9 is arranged at the corresponding position of the clamping member 44, and a proximity switch 10 connected to the control system is arranged on one side of the work table 2. The sensing member 9 is a magnetic block. When it is necessary to process multiple layers of fabrics at the same time, the fabrics are placed in sequence from top to bottom, and due to height issues, the rotating motor 47 is required to make the mounting frame 41 rise. During the rising process of the mounting frame 41, the sensing member 9 will sequentially trigger the proximity switch 10 from top to bottom, and the proximity switch 10 will sequentially control the drive motor 43 to start gradually from top to bottom through the control system, thereby driving the corresponding clamping member 44 and the detection component 45 to start. Example

[0054] like Figure 2 , 7 As shown, an air flow layer 11 is formed between adjacent clamping members 44, cooling nozzles 12 corresponding to the positions of several air flow layers 11 are arranged on the mounting frame 41, gas storage tanks 13 corresponding to several cooling nozzles 12 are arranged on the frame 1, and an electric valve electrically connected to the proximity switch 10 is arranged between the gas storage tank 13 and the cooling nozzle 12.

[0055] The airflow layer 11 disposed between two adjacent clamps 44 allows cold air to pass through the bottom of the fabric. The cooling nozzle 12 corresponding to the position of the airflow layer 11 sprays cooling airflow to the fabric cutting area during laser cutting to prevent the high temperature generated during the laser cutting process from damaging or melting the fabric edge. The airflow layer 11 is designed between the clamps 44 to effectively reduce the temperature of the cutting area and prevent the two adjacent layers of fabric from fusing.

[0056] Through the above equipment, the accuracy and speed of fabric cutting can be effectively improved, thereby improving the production efficiency and production quality of bachelor's caps.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
