[0041] like Figure 3 、 11 As shown, the roller shaft A27 where the transmission roller A26 is located rotates with the bracket 25, and the two gears C28 at both ends of the roller shaft A27 are respectively engaged with the gear D29 on the corresponding side of the bracket 25. The gear E30 on the shaft where the gear D29 is located is engaged with the gear F31 on the rotating shaft A3212 on the corresponding side of the bracket 25. The rotating shaft A3212 is transmission-connected to the output shaft of the motor B33 on the corresponding side; Figure 7 、 12 As shown, a ring sleeve 36 is nested and rotated on the roller shaft B35 where the transmission roller B34 is located. The ring sleeve 36 is fixedly connected to the turbine 38 installed on the corresponding side of the bracket 25 through a connecting rod 37 equipped with an air pipe B44. The turbine 38 is engaged with a worm 39 that rotates on the bracket 25.

[0043] like Figure 1 、 3 As shown in FIG5 , the pressing mechanism 51 includes a hydraulic cylinder 52, a plate seat 53, a telescopic rod 54, a return spring 59, a pressure roller A60, a vortex spring 63, a roller shaft C65, and a pressure roller B66. Figure 2 、 4As shown in Figure 5, four pressure rollers A60 corresponding to the first, second, sixth and seventh transmission rollers A26 on the front transmission section of the transmission mechanism 24 and three pairs of pressure rollers B66 corresponding to the third, fourth and fifth pressure rollers B66 on the front transmission section of the transmission mechanism 24 are installed under the plate seat 53 that moves vertically under the drive of the hydraulic cylinder 52; each pressure roller A60 is connected to the plate seat 53 through two telescopic rods 54, and the two roller shafts C65 of each pair of pressure rollers B66 are connected to the plate seat 53 through the telescopic rod 54 hinged thereto, and the telescopic rod 54 has a reset spring 59 for its vertical telescopic reset; a vortex spring 63 for its swing reset is matched between the rotating shaft C and the corresponding telescopic rod 54.

[0044] like Figure 5 As shown, the telescopic rod 54 consists of an outer sleeve 55 and an inner rod 57 that are connected to each other; the return spring 59 is in the corresponding outer sleeve 55; the rotating shaft C is installed on the swing seat 62, and the swing seat 62 is hinged to the support ear 61 at the lower end of the corresponding telescopic rod 54 through a hinge pin. The support ear 61 is equipped with two limit blocks 64 that correspond one-to-one with the swing seat 62 and limit the downward swing of the rotating shaft C.

[0045] like Figure 1 、 6 As shown in FIG. 7 , the shaping mechanism 23 includes a steam box 3, a cylinder 6, an electric push rod 9, a ring plate 10, a semi-ring rod 11, a rotating shaft A3212, a sealing film 13, and a motor A19. Figure 9 As shown, the lower end of the steam box 3 has three circular grooves 4 corresponding to the transmission mechanism 24 one by one; in each circular groove 4 6 and 7, there is a cylinder 6 driven by three electric push rods 9 sliding vertically, and the lower end of the cylinder 6 is equipped with a ring plate 10 that presses the edge of the hat against all the transmission rollers B34 of the corresponding transmission mechanism 24; three concentric semi-ring rods 11 are installed in the cylinder 6, and both ends of the semi-ring rods 11 are hinged to the cylinder 6 through the rotating shaft A3212 driven by the motor A19; a spherical sealing membrane 13 is installed between any two adjacent semi-ring rods 11, which closes the ring plate 10 when the three semi-ring rods 11 are unfolded; the bottom of the steam box 3 has a structure for evenly injecting steam into it; a sealing ring 14 is fitted between the two semi-ring rods 11 on both sides and the ring plate 10.

[0046] like Figure 7 、 8 As shown, a telescopic column that is vertically telescopic and transmission-connected to the output shaft of the motor A19 rotates in the guide sleeve 18 in the steam box 3; the gear B16 at the lower end of the telescopic shaft 17 meshes with the gear A15 on a rotating shaft A3212.

[0047] like Figure 6 、 7As shown in Figures 9 and 9, the top of the steam box 3 has three air inlet holes 5 which correspond one to one with the circular grooves 4 and are connected to the steam generator through the air pipe A20. Below each air inlet hole 5, a cone cover 22 is installed through four circumferentially evenly distributed fixing rods 21 for guiding the steam to diffuse evenly around the steam box 3.

[0048] like Figure 1 、 2 As shown, a multi-degree-of-freedom manipulator 67 is installed on the crossbeam above the bracket 25 of the transmission mechanism 24, which places the hat from the side on the transmission roller A26; a transmission belt A1 is installed on the ground to transport the hat to the front section of the three transmission mechanisms 24 and a transmission belt B2 is installed to transfer the hat that falls freely from the transmission roller B34 in the transmission mechanism 24.

[0049] like Figure 5 As shown, the inner rod 57 has two guide blocks 58 , and the two guide blocks 58 slide in the two guide grooves 56 on the inner wall of the corresponding outer sleeve 55 respectively.

[0050] like Figure 6 As shown, the cylinder 6 has three vertical guide rods 7 evenly distributed around the circumference. The three guide rods 7 are respectively sealed and slid in the circular holes on the top of the steam box 3 and connected to the ring 8. The ring 8 is driven by three electric push rods 9.

[0051] The middle parts of the two pressing rollers A60 in the pressing mechanism 51 close to the steam box 3 are each provided with an annular groove 50 for the top of the hat to pass over when being pressed flat and moving downwards to the shaping mechanism 23 .

[0052] The present invention operates as follows: In the initial state, the four pressure rollers A60 in the pressing mechanism 51 are at their maximum vertical distance from the corresponding transmission rollers A26. The vertical distances between the three pairs of pressure rollers B66 and the corresponding transmission rollers A26 are also at their maximum. Each pair of pressure rollers B66 is tilted downward at a certain angle, and the vortex spring 63 is compressed. Each telescopic rod 54 is fully extended, and the internal return spring 59 is compressed. All transmission rollers B34 in the transmission mechanism 24 are horizontal. The three ring plates 10 in the shaping mechanism 23 are at their maximum height. The three half-ring rods 11 in each cylinder 6 are in an extended state, and the ring plates 10 are closed by two sealing membranes 13, thereby preventing steam loss from the steam box 3.

[0053] When the present invention is used to heat and shape a hat, steam is sequentially injected into the steam box 3 through the three air inlets. Since each ring plate 10 is closed by the corresponding three sealing films 13, the heat of the steam in the steam box 3 will not be lost or will be very little lost. At the same time, the conveyor belts A1 and B2 are started, and the conveyor belt A1 conveys the hat to the three conveying mechanisms 24. At the same time, the air pipe B44 corresponding to each conveying roller B34 on the conveying mechanism 24 is opened so that the air pipe B44 ejects air upward.

[0054] When the hat on the conveyor belt A1 reaches the vicinity of the corresponding conveying mechanism 24, the robot 67 picks up the hat from the conveyor belt and inserts the hat from the side onto the conveyor roller A26 of the conveyor belt mechanism, and starts the hydraulic cylinder 52. The hydraulic cylinder 52 drives the four pressure rollers A60 and three pairs of pressure rollers B66 through the plate seat 53 to move toward the hat on the conveyor roller A26.

[0055] The two pressing rollers A60 on the outermost sides first press the edges of the hat against the corresponding transmission rollers A26, and the two inner pressing rollers A60 then press the edges of the hat against the corresponding transmission rollers A26, while the three pairs of pressing rollers in the middle press down the top of the hat in the middle. Since the end of each pressing roller B66 is tilted downward, in the process of the three pairs of pressing rollers B66 moving downward and pressing down the top of the hat in the middle, the three pairs of pressing rollers B66 simultaneously gather and squeeze the top of the hat in the middle and finally press the top of the hat down to a flat state. There is no overlap between the brim and the top of the hat, ensuring that in subsequent processes, the brim and the top of the hat cannot be effectively supported and shaped due to neutralization and overlap.

[0056] When the pressing mechanism 51 presses the hat down for a certain period of time, the two motors B33 in the transmission mechanism 24 are started. The two motors B33 drive a corresponding set of gears F31 and a set of gears L48 to rotate synchronously through the corresponding rotating shaft A3212. Each gear F31 drives all the transmission rollers A26 to rotate through the corresponding gear E30, gear D29, gear C28 and roller shaft A27. At the same time, each gear L48 drives all the transmission rollers B34 to rotate through the corresponding gear K47, gear J46, gear I45 and roller shaft B35.

[0057] The rotating conveyor rollers A26 and B34 eventually transfer the flattened cap to conveyor roller B34, where it faces the corresponding ring plate 10. At this point, motor B33 is stopped, keeping the cap firmly positioned on conveyor roller B34. After the cap is released from the ring groove 50 of pressure roller A60, hydraulic cylinder 52 is activated to position pressure roller A60 and pressure roller B66. During the reset process, pressure roller B66, under the action of vortex spring 63, swings upward a predetermined distance around the hinged joint between the corresponding swing seat 62 and the telescopic rod 54 to reset.

[0058] When the hat reaches the conveying roller B34 of the conveying mechanism 24, the corresponding three electric push rods 9 are first started. The electric push rods 9 drive the ring plate 10 through the ring 8, guide rod 7 and cylinder 6 to press the edge of the hat tightly against the conveying roller B34. At the same time, the air pipe B44 following each conveying roller B34 blows air into the top of the hat in the middle, so that the top of each flattened hat is completely propped up by the action of the gas below.

[0059] Start the motor A19, which drives a semi-ring rod 11 to swing 180 degrees through the telescopic shaft 17, gear B16, gear A15, and rotating shaft A3212, so that the three semi-ring rods 11 swing simultaneously and finally drive the sealing film 13 to open the ring plate 10, so that the steam in the steam box 3 can heat and shape the top of the hat supported by the gas below.

[0060] When the hat is heated and shaped, the motor A19 is started again. The motor A19 drives the three half-ring rods 11 to swing back around the rotating shaft A3212 through a series of transmissions, so that the two sealing films 13 close the ring plate 10 again to prevent the steam in the steam box 3 from leaking after the hat is taken away.

[0061] Then, the two motors C43 in the transmission mechanism 24 are started synchronously. The two motors C43 drive the transmission roller B34 on the corresponding roller shaft B35 to swing down 90 degrees around the axis of the corresponding turbine 38 through the corresponding rotating shaft B42, gear H41, gear G40, worm 39, turbine 38 connecting rod 37 and ring sleeve 36, so that the middle part of all the transmission rollers B34 in the rear section of the transmission mechanism 24 swings down and opens. The hat that has been shaped on the transmission roller B34 loses the support of the transmission roller B34 and falls freely to the conveyor belt B2 below to be transported away.

[0062] The entire hat shaping process is fully automated, saving labor costs and effectively improving hat shaping efficiency.

[0063] In summary, the present invention has the following beneficial effects: The present invention, through the cooperation of the pressing mechanism 51 and the conveying mechanism 24, initially compresses the hat placed on the conveying mechanism 24 into a flat shape with no overlap between the center and the edges, allowing the hat to be horizontally placed within the steam box 3 before being propped up and steam-heated for shaping. This effectively reduces the height of the steam box 3 and saves space. The hat is propped up within the steam box 3 by air pipes B44 blowing upward through the gaps between the pairs of conveying rollers B34 at the end of the conveying mechanism 24. Therefore, the present invention eliminates the problem of the hat shaping mold not matching the hat size. The present invention is suitable for shaping hats of any size and has wide adaptability.

[0064] In the present invention, a sealing film 13 is provided above the ring plate 10 that presses and fixes the edge of the flat hat to the transmission roller B34, which closes the ring plate 10 before the hat enters the range of the steam box 3 or after the hat is taken out of the range of the steam box 3, and opens the ring plate 10 after the hat enters the range of the steam box 3. The sealing film 13 can prevent the steam in the steam box 3 from leaking out through the ring plate 10, thereby achieving the purpose of energy saving.

[0065] In addition, the present invention fully automates the entire hat shaping process, thereby improving the hat shaping efficiency.
