Description

Technical Field

[0001] This utility model relates to a sewing machine suitable for tubular garments. Background Technology

[0002] When sewing a tube skirt or trousers, the seam allowance (the excess edge after two pieces of fabric are sewn together) needs to be ironed separately on both sides. Since the seam allowances on both sides are located inside the garment and may even come into direct contact with the skin, it is necessary to ensure that the seam allowances on both sides are flat and without bulges.

[0003] Currently, seam allowances are typically processed manually by ironing, which separates the seam and flattens it during the ironing process, but this method is inefficient. Alternatively, the seam allowances can be separated automatically, but this only splits the seam allowances on both sides and does not achieve the effect of flattening them, so further flattening processing is still required. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sewing machine suitable for tubular garments, which has high working efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

In the first working position, the adjusting member is located above the steam inlet, and the steam inlet is in communication with the heating channel; in the second working position, the adjusting member is inserted into the sealing member to prevent steam from entering the heating channel.

[0008] In a preferred embodiment, the heating channel is serpentine in shape.

[0009] In a preferred embodiment, the heating module has an inlet and an outlet, the heating channel is located between the inlet and the outlet, the hollow portion of the sealing member is connected to the inlet, and the outlet is connected to the first through hole of the pressure roller.

[0010] In a preferred embodiment, the slit machine further includes an air suction mechanism located below the conveyor belt. The air suction mechanism includes a perforated plate and a fan. The conveyor belt is provided with a plurality of second through holes, and the perforated plate has a plurality of third through holes communicating with the second through holes. The fan is connected to the third through holes through a connecting module.

[0011] In a preferred embodiment, the communication module includes a housing and an air inlet disposed on the housing, the air inlet being connected to the third through hole of the conveying platform, and the fan being connected to the air inlet via a pipe.

[0012] In another preferred embodiment, the communication module further includes a drain port located on the housing, and a partition plate is provided inside the cavity of the housing to prevent liquid from entering the fan.

[0015] The present invention adopts the above solution and has the following advantages compared with the prior art:

[0016] The sew-opening machine of this utility model first passes through a slitting mechanism to separate the seam allowances on both sides of a tubular garment. The separated seam allowances are then conveyed by a conveyor belt to the area directly below a pressure roller. While the pressure roller presses down on the seam allowances, it sprays steam through a first through-hole to iron the seam allowances flat, ensuring that the seam allowances on both sides are flat and without protrusions. In other words, this sew-opening machine can not only perform the function of opening seams, but also iron the seam allowances, resulting in high work efficiency. Attached Figure Description

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Reference Figure 1 As shown, this embodiment provides a seam-opening machine suitable for tubular garments, where tubular garments refer to trousers, skirts, or long-sleeved garments, etc. This seam-opening machine is mainly used to open and iron the seams of these garments. The seam-opening machine includes a frame 1, a machine head 2, a conveyor table 3, and a garment storage space 5. The machine head 2 and the conveyor table 3 are mounted on the frame 1. The machine head 2 is roughly L-shaped, and the conveyor table 3 is generally arc-shaped. The conveyor table 3 is located between the machine head 2 and the garment storage space 5, which is located directly below the conveyor table 3 and can be used to store clothing.

[0034] Furthermore, combined Figure 1 , 2 and Figure 8 As shown, the machine head 2 includes an ironing mechanism 21 and a seam-sewing mechanism 33. The conveyor table 3 includes a conveyor belt 31 and a suction mechanism 32. The conveyor belt 31 is located between the ironing mechanism 21 and the suction mechanism 32, and the conveyor belt 31 is provided with multiple second through holes (not shown in the figure). The seam-sewing mechanism 33 is located in front of the ironing mechanism 21. The direction of movement of the conveyor belt 31 can be referenced to the direction of movement of the conveyor belt 31, which moves from front to back. More specifically, the conveyor belt 31 is used to transport the garment. The ironing mechanism 21 is located above the conveyor belt 31, and the suction mechanism 32 is located below the conveyor belt 31. The seam-sewing machine first separates the seams on both sides of the garment through the seam-sewing mechanism 33 in front, and then uses the ironing mechanism 21 above to iron the separated seams. At the same time, the suction mechanism 32 located below the conveyor belt 31 attracts the garment, forming a negative pressure, making the ironing process more stable.

[0035] Furthermore, the ironing mechanism 21 includes a pressure roller 211 capable of rotating around its own axis and a housing 214 covering the pressure roller 211. At least a portion of the pressure roller 211 abuts against the tubular garment. The pressure roller 211 is driven to rotate by a drive mechanism 25. The drive mechanism 25 is existing technology and can be a motor, etc., which is not the focus of this utility model and will not be described in detail here. It should be noted that the bottom of the housing 214 has a hollow section to allow part of the pressure roller 211 to be exposed in the housing, facilitating ironing of the garment. The pressure roller 211 is provided with a plurality of first through holes 212 for spraying steam onto the garment. The diameter of the first through holes 212 is 1-2 mm. Specifically, the pressure roller 211 is cylindrical in shape, and the first through holes 212 are spaced apart on the entire circumferential surface of the pressure roller 211, with a diameter of 1 mm.

[0036] Reference Figures 3 to 6 As shown, the ironing mechanism 21 also includes a drive cylinder 22, an adjusting component 23, a heating module 24, and a steam inlet 213 located above the pressure roller 211. The adjusting component 23 is connected to the drive cylinder 22, and the drive cylinder 22 drives the adjusting component 23 to move in the vertical direction. The function of the heating module 24 is to prevent steam liquefaction, and the heating module 24 is located below the adjusting component 23. The steam inlet 213 is connected to an external steam pipe or steam oven.

[0037] Furthermore, the heating module 24 has a heating channel 241, a heating element 242 for heating the heating channel 241, and a sealing element 243 that cooperates with the adjusting element 23. The heating channel 241 is serpentine in shape, which extends the heating path and can heat the steam more effectively. The adjusting element 23 can move in the vertical direction relative to the sealing element 243. Furthermore, the sealing element 243 has a hollow portion 2431, and the adjusting element 23 can be inserted into the hollow portion 2431. The adjusting element 23 has a first working position and a second working position. In the first working position, the adjusting element 23 is located above the steam inlet 213, and the steam inlet 213 is connected to the heating channel 241. In the second working position, the adjusting element 23 is inserted into the sealing element 243 to prevent steam from entering the heating channel 241.

[0038] Furthermore, combining Figure 5 As shown, the heating module 24 has an inlet 244 and an outlet 245. A heating channel 241 is located between the inlet 244 and the outlet 245. A sealing member 243 is inserted into the inlet 244, and the hollow portion 2431 of the sealing member 243 is connected to the inlet 244. The outlet 245 is connected to the first through hole 212 of the pressure roller 211. When the regulating member 23 is in the first working position, steam enters the pressure roller 211 sequentially through the steam inlet 213, the hollow portion 2431 of the sealing member 243, the heating channel 241, and the outlet 245.

[0039] The shape of the slit dividing mechanism 33 is similar to a "mountain" shape. The slit dividing mechanism 33 is located above the conveyor belt 31. After the seam allowances of the tubular garment are separated by the slit dividing mechanism 33, they are then ironed flat by the ironing mechanism 21. Specifically, the slit dividing mechanism 33 includes a bifurcated portion 331 which is used to separate the seam allowances on both sides of the tubular garment.

[0040] Refer to Figure 8 As shown, the air suction mechanism 32 is located below the conveyor belt 31. The air suction mechanism 32 includes a perforated plate 321 and a blower 322. The perforated plate 321 has a plurality of third through holes 3211 to adsorb the garment on the conveyor belt 31. The third through holes 3211 communicate with the second through holes on the conveyor belt 31, and the blower 322 communicates with the third through holes 3211 through the connection module 4.

[0041] Further, as combined Figure 7 As shown, the connection module 4 includes a housing 41, an air inlet 42 and a liquid discharge port 43 located on the housing 41. The liquid discharge port 43 and the air inlet 42 are inserted into the cavity 411 of the housing 41. The air inlet 42 on the housing 41 communicates with the third through holes 3211 of the conveying table 3, and the blower 322 communicates with the air inlet 42 through a pipeline 34. Further, a partition plate 44 is also provided in the cavity 411 to prevent liquid from entering the blower 322. During the operation of the slitting machine, the steam may liquefy into liquid. At this time, the liquid discharge port 43 is required to discharge the liquid, and the blower 322 is also operating while discharging the liquid. In order to prevent the liquid from entering the blower 322 through the pipeline 34, the partition plate 44 is designed to separate the liquid discharge port 43 and the pipeline 34.

[0042] In this embodiment, first, the bifurcated portion 331 of the slit dividing mechanism 33 is used to separate the seam allowances on both sides of the garment. The garment is conveyed by the conveyor belt 31 to directly below the pressing wheel 211, and the pressing wheel 211 irons the seam allowances to make the seam allowances on both sides flat. The working efficiency is relatively high and energy-saving.
