[0031] See also Figures 1 to 5 The present invention provides a brim processing fixture. The brim processing fixture includes an upper clamping die 1 and a lower clamping die 2 that are hingedly arranged. There is a shaping space 101 between the upper clamping die 1 and the lower clamping die 2 for accommodating a sheet of material. The upper clamping die 1 and the lower clamping die 2 are provided with sewing grooves 102 respectively. The upper clamping die 1 has a first accommodating cavity 11 and a second accommodating cavity 12 arranged in upper and lower positions. The lower clamping die 2 has a third accommodating cavity 21 and a fourth accommodating cavity 22 arranged in upper and lower positions. The first accommodating cavity 11 is provided with a first air duct 13, and the fourth accommodating cavity 22 is provided with a third accommodating cavity 21 and a fourth accommodating cavity 22. Two air ducts 23, the first air duct 13 and the second air duct 23 are both connected to an external exhaust fan, the first air duct 13 is provided with multiple first suction ducts 131, the suction port of the first suction duct 131 is set on the lower end surface of the upper clamping mold 1, the fourth accommodating cavity 22 is provided with a second air duct 23, the second air duct 23 is provided with multiple second suction ducts 231, the suction port of the second suction duct 231 is set on the upper end surface of the lower clamping mold 2, and the second accommodating cavity 12 and the third accommodating cavity 21 are both provided with electric heating wires 3.

[0032] In this example, see Figures 1 to 5The lower end surface of the upper clamping mold 1 and the upper end surface of the lower clamping mold 2 are both arc-shaped. The shape of the molding space 101 formed after the upper clamping mold 1 and the lower clamping mold 2 are buckled together is the molding shape of the brim. In this embodiment, the sewing groove 102 is U-shaped. During processing, the sewing machine head can sew the material piece with the help of the sewing groove 102. In this embodiment, a first partition layer 16 is provided between the first accommodating chamber 11 and the second accommodating chamber 12, and a second partition layer 25 is provided between the third accommodating chamber 21 and the fourth accommodating chamber 22, wherein the first air duct 13 is located inside the sewn groove 102 and is fixed on the first partition layer 16, and the first air duct 13 includes three long tubes 1301 arranged at intervals along the width direction of the upper clamping mold 1, and the length direction of the three long tubes 1301 is the same as the length direction of the upper clamping mold 1, and the same side ends of the three long tubes 1301 are connected by a bent tube 1302, and multiple first suction tubes 131 are arranged on the three long tubes 1301 and the bent tube 1302, and the first suction tube 131 passes through the first partition layer 16 and the second accommodating chamber 12 and is connected to the lower side wall of the upper clamping mold 1, and is connected to the outside world through the suction port provided on the lower end face of the upper clamping mold 1. In this embodiment, the arrangement of the second air duct 23 in the lower mold 2 is the same as the arrangement of the first air duct 13 in the upper mold 1, which will not be elaborated here. When in use, first turn on the external exhaust fan, then stick the upper piece on the lower end surface of the upper mold 1, and stick the lower piece on the lower end surface of the lower mold 2. The exhaust fan is used to generate suction between the first air duct 13 and the second air duct 23, and with the help of the suction port, the upper piece can be adsorbed on the upper mold 1, and the lower piece can be adsorbed on the lower mold 2, and then the upper mold 1 and the lower mold 2 are buckled together, so that the upper piece and the lower piece can be fixed and sewn according to the final forming shape of the brim.

[0033] The brim processing fixture provided by the present invention, compared with the prior art, has the following advantages: during processing, the upper piece is fixed on the upper clamping mold 1 by the suction force generated by the first suction pipe 131, and the lower piece is fixed on the lower clamping mold 2 by the suction force generated by the second suction pipe 231, so that the upper piece is fitted with the lower end surface of the upper clamping mold 1, and the lower piece is fitted with the upper end surface of the lower clamping mold 2. After the upper clamping mold 1 and the lower clamping mold 2 are buckled together, the upper piece and the lower piece are pressed into the shaping space 101, so that the shapes of the upper piece and the lower piece can be kept consistent with the final shape of the brim during sewing, thereby reducing the problem of uneven tightness of the stitches after sewing and the generation of wrinkles. In addition, by providing the electric heating wire 3, the upper piece and the lower piece can be ironed and shaped after sewing, which further ensures the stability of the shape of the piece after sewing, reduces the number of clamping times during brim processing, and improves production efficiency.

[0034] In some embodiments, see Figures 1 to 5, first positioning strips 103 are provided on both sides of the width direction of the upper clamping mold 1, and first positioning teeth 1031 are provided on the first positioning strips 103 at intervals along its length direction. Second positioning strips 104 are provided on both sides of the width direction of the lower clamping mold 2, and second positioning strips 1041 are provided on the second positioning strips 104 along its length direction corresponding to the first positioning teeth 1031. The corresponding first positioning teeth 1031 are engaged with the second positioning teeth 1041. When in use, the first positioning teeth 1031 form a positioning effect on the upper piece, and the second positioning teeth 1041 form a positioning effect on the lower piece, so that the upper piece and the lower piece are accurately positioned during sewing, and there will be no misalignment after sewing.

[0035] In some embodiments, see Figures 1 to 5 , a plurality of first support columns 14 are provided in the upper clamping mold 1, and the first support columns 14 pass through the first accommodating cavity 11 and the second accommodating cavity 12 and are connected between the upper side wall and the lower side wall of the upper clamping mold 1, and a plurality of second support columns 24 are provided in the lower clamping mold 2, and the second support columns 24 pass through the second accommodating cavity 12 and the fourth accommodating cavity 22 and are connected between the upper side wall and the lower side wall of the lower clamping mold 2. In this embodiment, the number of the first support columns 14 and the second support columns 24 are both two, and the two first support columns 14 are respectively arranged in the two intervals formed by the three long tubes 1301, and the first support columns 14 pass through the first partition layer 16 and are fixed by the first partition layer 16. The second support columns 24 correspond to the first support columns 14 and have the same layout. By arranging the first support columns 14 and the second support columns 24, the lower end face of the upper clamping mold 1 and the upper end face of the lower clamping mold 2 are effectively supported, thereby enhancing their anti-deformation ability and improving their service life.

[0036] Further, see Figures 1 to 5 The first support column 14 and the second support column 24 are both cylindrical iron cores, and a coil 4 is wound on the first support column 14 and the second support column 24. The coil 4 wound on the first support column 14 is located in the second accommodating chamber 12 and is electrically connected to the electric heating wire 3 arranged in the second accommodating chamber 12. The coil 4 wound on the second support column 24 is located in the fourth accommodating chamber 22 and is electrically connected to the electric heating wire 3 arranged in the third accommodating chamber 21. In use, when the electric heating wire 3 is energized, the first support column 14 and the second support column 24 are magnetized through the action of the coil 4. By arranging the winding direction of the coil 4, the magnetic force generated by the first support column 14 and the second support column 24 can be attracted to each other. In this way, under the action of the magnetic force of the first support column 14 and the second support column 24, the upper and lower sheets can be tightly squeezed together, thereby enhancing the ironing and shaping effect of the electric heating wire 3.

[0037] Further, see Figures 1 to 5In order to further enhance the ironing and shaping effect, a water supply pipe 15 is further provided in the first accommodating chamber 11. The water supply end of the water supply pipe 15 is connected to an external water source. A plurality of water outlet pipes 1501 are provided on the water supply pipe 15. The water outlets of the water outlet pipes 1501 are set on the lower end surface of the upper clamping mold 1. When in use, water is supplied through the water supply pipe 15 to moisten the sheet, and high-temperature steam is generated under the heat action of the electric heating wire 3. The high-temperature steam is used to iron the sheet, thereby improving the ironing effect.

[0038] Specifically, see Figures 1 to 5 The water supply pipe 15 is fixed on the first partition layer 16, and includes a first water pipe 151 and a second water pipe 152 arranged at intervals along the width direction of the upper clamping mold 1. The length direction of the first water pipe 151 and the second water pipe 152 is the same as the length direction of the upper clamping mold 1. The first water pipe 151 and the second water pipe 152 are located between the two first support columns 14 and are symmetrical with respect to the middle long pipe 1301. A plurality of water outlet pipes 1501 are arranged at intervals on the first water pipe 151 and the second water pipe 152. The water outlet pipes 1501 penetrate downwardly through the first partition layer 16 and the first partition layer 16. The second accommodating chamber 12 is connected to the lower end surface of the upper mold 1 and communicates with the outside world through a water outlet provided on the lower end surface of the upper mold 1. To enhance the diffusion of water on the web, a plurality of water diversion grooves 1502 are engraved on the lower end surface of the upper mold 1, which communicate with the outlet of the water outlet pipe 1501. In this embodiment, the water diversion grooves 1502 are spaced apart along the length of the upper mold 1 and extend along the width of the upper mold 1. It should be noted that neither the water diversion grooves 1502 nor the outlet of the water outlet pipe 1501 are connected to the air intake of the first suction pipe 131. During use, water can quickly spread over most of the web through the water diversion grooves 1502, enhancing the wetting effect on the web.

[0039] In some embodiments, see Figure 3 、 Figures 6 to 9The first accommodating chamber 11 is provided with a connecting component 5, and the connecting component 5 is provided with a first chamber 51, a second chamber 52 and a third chamber 53 connected in sequence. The first chamber 51 is provided with a first port 501 connected to an external water source, the second chamber 52 is provided with a second port 502 connected to the water supply pipe 15, and the third chamber 53 is provided with a third port 503 connected to the first air duct 13. A first diaphragm 54 is provided between the first chamber 51 and the second chamber 52, and a first through hole 541 is provided on the first diaphragm 54. A second diaphragm 56 is provided between the second chamber 52 and the third chamber 53, and a second through hole 561 is provided on the second diaphragm 56. A piston 55 is slidably provided between the first diaphragm 54 and the second diaphragm 56. In the second chamber 52, the chamber between the piston 55 and the first diaphragm 54 is a first connecting chamber 521. The second port 502 is provided in the first connecting chamber 521. The piston The chamber between 55 and the second diaphragm 56 is the second connecting chamber 522, and a first spring 57 is provided in the second connecting chamber 522. When in the non-operating state, the piston 55 abuts against the first through hole 541 under the elastic action of the first spring 57, so that the first chamber 51 and the first connecting chamber 521 are not connected to each other, so that the water in the first chamber 51 cannot flow into the water supply pipe 15. During operation, when the upper sheet is attached to the lower end surface of the upper clamping mold 1, the air suction port is blocked. Under the continuous operation of the exhaust fan, a negative pressure is generated in the first air duct 13. Under the action of the negative pressure, the atmosphere presses the piston 55, and the piston 55 moves toward the side of the second diaphragm 56 to compress the first spring 57, so that the piston 55 no longer blocks the first through hole 541, so that the first chamber 51 and the first connecting chamber 521 are connected, and water enters the water supply pipe 15 from the first chamber 51 to wet the sheet.

[0040] Further, see Figures 6 to 9A gate plate 58 is slidingly provided in the third chamber 53. The gate plate 58 is located between the two first support columns 14. The sliding direction of the gate plate 58 is the same as the direction of the line connecting the two first support columns 14. A permanent magnet 581 is provided at the end of the gate plate 58 close to the first support column 14. A second spring 59 is provided between the gate plate 58 and the side wall of the third chamber 53. In this embodiment, the permanent magnets 581 at both ends of the gate plate 58 have opposite magnetic properties. During use, when the coil 4 is energized, the two first support columns 14 generate magnetism through electromagnetic induction. One of the two permanent magnets 581 on the gate plate 58 is attracted by the magnetism generated by the first support column 14 on the same side, and the other is repelled by the magnetic force generated by the first support column 14 on the same side. In this way, under the action of the magnetic force of the two first support columns 14, the gate plate 58 can be pushed to one side, compressing or stretching the second spring 59 and forming a blockage on the third port 503. In this way, the piston 55 is no longer affected by the negative pressure of the first air duct 13. Under the elastic force of the first spring 57, the piston 55 moves to the side of the first diaphragm 54 to re-block the first through hole 541, so that the water supply pipe 15 stops supplying water. Such a setting can avoid excessive water supply, so that the sheet will not be too wet, reduce the operating difficulties of the electric heating wire 3, and improve operating efficiency.

[0041] In some embodiments, a main power supply circuit is also provided on the upper clamping mold 1, and a first branch and a second branch are connected in parallel on the main power supply circuit. The external exhaust fan is connected in series on the first branch, the electric heating wire 3 is connected in series on the second branch, a first switch is connected in series on the main power supply circuit, and a second switch is connected in series on the second branch.

[0042] Optionally, the second switch includes a plug provided on the upper clamping mold 1 and a socket provided on the lower clamping mold 2, wherein the upper clamping mold 1 is snapped onto the lower clamping mold 2 so that the plug is inserted into the socket to open the second branch.

[0043] In this embodiment, operating the clamp described in the present invention includes the following steps. When in use, first open the upper clamp 1 and the lower clamp 2, close the first switch to start the exhaust fan, and then respectively attach the upper sheet to the upper clamp 1 and the lower sheet to the lower clamp 2. After the upper sheet and the lower sheet are adsorbed and fixed, under the action of the exhaust fan, a negative pressure is generated in the first air duct 13, and the negative pressure causes the piston 55 to move toward the side of the second partition 56, so that the water supply source is connected to the water supply pipe 15 and starts to supply water. At this time, the upper clamp 1 is buckled onto the lower clamp 2, and the plug of the upper clamp 1 is plugged into the socket of the lower clamp 2, so that the second switch is closed, the coil 4 and the electric heating wire 3 are energized, so that the first support column 14 and the second support column 24 generate a magnetic force of attraction, thereby clamping the upper clamp 1 and the lower clamp 2. At the same time, Under the action of the magnetic force of the support column 14, the gate 58 is pushed to one side, closing the third port 503, so that the piston 55 is no longer affected by the negative pressure, and is reset under the elastic force of the first spring 57, forming a blockage for the first through hole 541, and the water supply pipe 15 stops supplying water. The sewing machine head starts to sew the material pieces, and at the same time the electric heating wire 3 starts to heat and iron. Sewing and ironing are carried out simultaneously, which improves production efficiency. After sewing and ironing are completed, the first switch is turned off, the exhaust fan stops running, the coil 4 and the electric heating wire 3 stop being energized, the magnetism of the first support column 14 and the second support column 24 disappears, and the gate 58 is reset. At this time, the upper clamp 1 can be easily removed from the lower clamp 2, so that the plug and the socket are separated, that is, the second switch is disconnected, and then the sewn brim is taken out from the lower clamp 2 to complete the sewing of the brim.

[0044] 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 and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
