Abstract
Description
Technical Field
[0001] This utility model relates to the field of garment processing technology, and in particular to a feeding device for overlocking protective clothing overlocking strips in an overlocking machine. Background Technology
[0002] The overlocking process is frequently used in the manufacturing of protective clothing and other garments. It involves joining two pieces of cut fabric together on the side that needs to be joined, placing a strip of fabric between the two pieces, and then overlocking one side. After unfolding, this process connects the two pieces of fabric to form a complete garment. The strip of fabric protrudes slightly at the seam after overlocking, and its color, different from the fabric, serves both decorative and reinforcing purposes.
[0003] Currently, the main process steps need to be completed in two steps: first, the strip is folded and sewn into shape for later use, and then the strip is sandwiched between two pieces of fabric for overlocking, which leads to low efficiency and increased production costs. Utility Model Content
[0004] The purpose of this invention is to provide a feeding device for the overlock trim of protective clothing for an overlock machine, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A feeding device for overlock sewing machine protective clothing overlock strips includes a guide housing. One end of the guide housing has a vertically flat inlet, and the other end has a horizontally flat outlet. The inlet and outlet are connected to form a guide channel one. The guide channel one gradually narrows from the inlet to the outlet. A downwardly curved extension arc plate is connected to one side of the outlet of the guide housing. Several guide frames are installed at intervals on the extension arc plate. The number of guide frames is not less than two. A horizontally flat guide channel two is provided through the guide frames. The guide channel one and the several guide channels two form an interval arc-shaped channel. The width of the guide channels two is equal to that of the outlet and is smaller than the width of the inlet. A fixing plate is connected to the end of the extension arc plate.
[0006] Preferably, a feed crank is installed on the guide housing at the feed inlet, and the feed crank is composed of multiple U-shaped parts.
[0007] Preferably, the guide housing has a guide groove, which is connected to the guide channel.
[0008] Preferably, there are two guide frames, including guide frame one set on the bottom extension arc plate of the discharge port and guide frame two set at the end of the extension arc plate.
[0009] Preferably, the fixing plate has fixing holes.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention features a downward-curving extension arc plate at the outlet of the guide housing, with several guide frames connected to the extension arc plate. A fixing plate is provided at the bottom of the extension arc plate, facilitating the vertical and tilted installation of the device on the needle plate at the presser foot of the overlock machine. This avoids obstructing the operator's hands during use. The clamping strip is guided and folded through the arc-shaped channel of the guide housing and guide frames before entering the presser foot for a short section of overlock sewing. During use, one side of each of the two pieces of fabric is attached to the upper and lower sides of the clamping strip after overlock sewing. Pulling the fabric and clamping strip from the bottom of the presser foot of the overlock machine allows for one-time overlock sewing, which is convenient, quick, reduces process steps, and improves garment processing efficiency.

[0013] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0014] like Figure 1-2 As shown, a feeding device for overlock sewing machine protective clothing overlock strips includes a guide housing 1. One end of the guide housing 1 is provided with a vertically flat inlet 2, and the other end is provided with a horizontally flat outlet 3. The inlet 2 and the outlet 3 are connected to form a guide channel 1. The guide channel 1 gradually narrows from the inlet 2 to the outlet 3. A downwardly curved extension arc plate 6 is connected to one side of the outlet 3 of the guide housing 1. Two guide frames are installed at intervals on the extension arc plate 6, including a guide frame 1 7 set on the extension arc plate 6 at the bottom of the outlet 3 and a guide frame 2 8 set at the end of the extension arc plate 6.
[0015] A horizontally flat guide channel 2 is provided through the guide frame 1 7 and the guide frame 2 8. The guide channel 1 and the two guide channels 2 form an intermittent arc-shaped channel. The width of the guide channel 2 is equal to that of the discharge port 3 and is smaller than the width of the feed port 2.
[0016] A feed crank 4 is installed on the guide housing 1 at the feed inlet 2. The feed crank 4 is composed of multiple U-shaped parts. By setting multiple U-shaped parts, the clamping strip 16 can be straightened.
[0017] The guide housing 1 is provided with a guide groove 5, which is connected to the guide channel 1, so as to guide the clamping bar 16 through the guide groove 5 so that it passes through the discharge port 3.
[0018] The end of the extended arc plate 6 is connected to a fixing plate 9. The fixing plate 9 has a fixing hole 10. Through the setting of the fixing hole 10, a fixing rod, fixing nail or threaded nail can be inserted into the fixing hole 10, so that the device can be vertically tilted and installed on the needle plate 13 at the presser foot 12 of the overlock machine 11. The exit of the guide frame 2 8 at the end is located on the side of the raised edge of the presser foot 12, which makes it easy to guide the neatly folded strip 16 under the presser foot 12 for sewing.
[0019] like Figure 1 and Figure 3 As shown, in use, the fixing plate 9 is installed on the needle plate 13 through the fixing hole 10, so that the outlet of the guide frame 2 8 is aligned with the lower side of the raised edge of the presser foot 12. The clamping strip 16 is wrapped around the feed crank 4, and then the flat part 17 of the clamping strip 16 is introduced into the feed port 2. The clamping strip 16 is led out of the discharge port 3 through the guide groove 5. Since the width of the discharge port 3 is smaller than that of the feed port 2, the clamping strip 16 in the guide housing 1 forms a bent part 18, and the clamping strip 16 at the discharge port 3 forms a folded part 19 in a folded and fitted state. Then, it passes through the guide frame 1 7 and the guide frame 2 8 in sequence, and the guide housing 1 and the guide frame 1 7 and the guide frame 2 8 pass through the guide frame 2 8. The opening between the two 8 sections facilitates the adjustment of the posture of the folded part 19 of the clamp strip 16, making the folded part 19 flat and aligned. Finally, the clamp strip 16 is introduced under the presser foot 12 and a short section is first overlocked. Then, the sewn parts 20 of fabric 14 and fabric 25 are respectively attached to the sewn parts 20 on the upper and lower sides of the clamp strip 16 under the presser foot 12. By manually pulling fabric 14, fabric 25 and the middle clamp strip 16 from the bottom of the presser foot 12 of the overlock machine 11, the overlocking can be completed in one go, which is convenient and quick, reduces the number of steps, and improves the efficiency of garment processing.
