Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, specifically to a polyester filament cutting device. Background Technology
[0002] Polyester filament is the commercial name for polyester fiber in China. Its characteristics include resistance to chemicals and frequent washing, reducing fading and discoloration in clothing. Therefore, it is used in the manufacture of hotel uniforms, stonewashed denim, sportswear, and children's clothing. Relatively speaking, polyester filament is more durable than rayon. When embroidering, the high-speed operation of the machine allows the high-tenacity polyester thread to withstand significant tensile force. Furthermore, it has extremely high fire resistance, making it resistant to fire even when the garment is near a flame.
[0003] In the current polyester filament manufacturing process, filament cutting is an essential step. Currently, polyester filament is generally guided by a guide roller. To ensure that the filament does not easily deviate during the transmission process, the guide roller is usually equipped with a guide groove. However, if the polyester filament located on the guide groove is to be cut, the presence of the guide groove makes it impossible to completely cut the polyester filament, which easily leads to filament cutting failure. Utility Model Content
[0004] The present invention provides a polyester filament cutting device to solve the above-mentioned technical problems. The device is designed with a wire assembly with a guide groove, on which the polyester filament can be cut.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model for a polyester filament cutting device is as follows:
[0006] The device includes a wire seat, on which a wire assembly is detachably connected. The wire assembly includes a rotating shaft, a front limiting half-shell, a rear limiting half-shell, and a wire wheel. The wire assembly is detachably connected to the wire seat via the rotating shaft. The wire wheel is rotatably connected to the rotating shaft. The front and rear limiting half-shells are respectively fitted onto the front and rear sides of the wire wheel, and both the front and rear limiting half-shells are connected to the rotating shaft by bolts. An outer ring is connected to the middle of the wire wheel. Both the front and rear limiting half-shells have slits on their upper parts. After the front and rear limiting half-shells are connected, the bottom wall of the slit is flush with the upper end of the outer ring, and a wire guide groove is formed between the front and rear limiting half-shells. A wire cutter is vertically slidably connected to the wire seat. A blade is installed on the wire cutter directly above the slit. A control mechanism for controlling the up-and-down movement of the wire cutter is also connected to the wire seat.
[0007] The conductor seat has a first insertion hole; the end of the rotating shaft is inserted into the insertion hole and connected to the conductor seat by bolts.
[0008] The wire seat has a second insertion hole on both the left and right sides; a connecting shaft is inserted into each of the second insertion holes; the connecting shaft is connected to the wire seat by bolts; a wire roller is rotatably connected to the connecting shaft.
[0009] The wire base is connected to mounting panels on both the upper and lower sides; each mounting panel has a connection hole.
[0010] The wire seat has a vertical groove; the shredder is connected to a slide block at the rear; the slide block is slidably connected to the vertical groove, and a limit block is connected to the rear end of the slide block; the slide block is limited to the vertical groove by the limit block and the shredder.
[0011] The control mechanism includes a pump body and a vertical telescopic push rod connected to the pump body; the pump body is installed above the lead wire seat; the lower end of the vertical telescopic push rod is connected to the slide.
[0012] The upper end of the blade is connected to a blade holder; the blade holder is connected to the shredder by bolts.
[0013] The technical effects that this utility model can achieve are:
[0014] 1. The wire assembly of this utility model conducts polyester filament through a wire wheel and limits the polyester filament by a front limiting half-shell and a rear limiting half-shell. The design of connecting the front limiting half-shell and the rear limiting half-shell to the rotating shaft by bolts ensures that the cut always faces upward. Therefore, the cut is always located directly below the blade. After the front limiting half-shell and the rear limiting half-shell are connected, the bottom wall of the cut is flush with the upper end of the outer ring. Therefore, when the blade comes down to cut the polyester filament, the polyester filament is easily and completely cut, thus completing the filament cutting.
[0015] 2. The entire wire assembly of this utility model adopts a detachable connection structure, which makes it easy to replace after damage. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.
[0024] See Figures 1 to 6 .
[0025] A polyester filament cutting device includes a wire seat 1, on which a wire assembly is detachably connected. The wire assembly includes a rotating shaft 2, a front limiting half-shell 3, a rear limiting half-shell 4, and a wire wheel 5. The wire assembly is detachably connected to the wire seat 1 via the rotating shaft 2. Specifically, the wire seat 1 has a first insertion hole 11, and the rear end of the rotating shaft 2 is inserted into the insertion hole 11 and connected to the wire seat 1 by bolts. The wire wheel 5 is rotatably connected to the rotating shaft 2. The front limiting half-shell 3 and the rear limiting half-shell 4 are respectively fitted on the front and rear sides of the wire wheel 5, and both the front limiting half-shell 3 and the rear limiting half-shell 4 are connected to the rotating shaft 2 by bolts. An outer ring 6 is connected to the middle of the wire wheel 5, and a slit 7 is opened on the upper part of both the front limiting half-shell 3 and the rear limiting half-shell 4. After the front limiting half-shell 3 and the rear limiting half-shell 4 are connected, the bottom wall of the slit 7 is flush with the upper end of the outer ring 6, and a wire guide groove 10 is formed between the front limiting half-shell 3 and the rear limiting half-shell 4.
[0026] A slidable shredder 8 is vertically slidably connected to the wire guide 1. Specifically, a vertical groove 21 is provided on the wire guide 1, and a slide 22 is connected to the rear side of the shredder 8. The slide 22 is slidably connected to the vertical groove 21, and a limit block 23 is connected to the rear end of the slide 22. The slide 22 is limited to the vertical groove 21 by the limit block 23 and the shredder 8. A blade 9 is installed on the shredder 8, located directly above the cut 7. Specifically, a blade holder 41 is connected to the upper end of the blade 9, and the blade holder 41 is connected to the shredder 8 by bolts. A control mechanism for controlling the up and down movement of the shredder 8 is also connected to the wire guide 1. Specifically, the control mechanism includes a pump body 31 and a vertical telescopic push rod 32 connected to the pump body 31. The pump body 31 is installed above the wire guide 1, and the lower end of the vertical telescopic push rod 32 is connected to the slide 22.
[0027] Instructions for use: During transmission, the polyester filament of this invention is positioned between the outer ring 6, the front limiting half-shell 3, and the rear limiting half-shell 4. The front and rear limiting half-shells 3 and 4 limit the polyester filament's movement forward and backward, and the transmission is facilitated by the guide wheel 5. Since the rotating shaft 2 itself does not rotate, the design of connecting both the front and rear limiting half-shells 3 and 4 to the shaft 2 via bolts ensures that the cut 7 always faces upward, meaning the cut 7 is always directly below the blade 9. Furthermore, after the front and rear limiting half-shells 3 and 4 are connected, the bottom wall of the cut 7 is flush with the upper end of the outer ring 6 (see reference). Figure 5 Therefore, the polyester filament can be completely cut during the downward movement of the blade 9. In the process of controlling the up and down movement of the blade 9, the pump body 31 needs to be opened first. The vertical extension and retraction of the vertical extension push rod 32 is controlled by the pump body 31 to control the up and down movement of the blade 9 and the wire seat 1.
[0028] The rotating shaft 2, the front limiting half shell 3, the rear limiting half shell 4, and the guide wheel 5 of this utility model are all connected by a detachable connection structure, which makes it convenient to replace them after damage.
[0029] Preferably, the wire seat 1 has a second insertion hole 12 on both the left and right sides, and a connecting shaft 13 is inserted into each of the second insertion holes 12. The connecting shaft 13 is connected to the wire seat 1 by bolts, and a wire roller 14 is rotatably connected to the connecting shaft 13. The wire seat 1 has a mounting panel 15 on both the upper and lower sides, and a connecting hole 16 is opened on each of the mounting panels 15.
[0030] This invention facilitates the conduction of polyester filaments by designing wire rollers 14 on both sides of the wire assembly; and by designing connecting holes 16, it facilitates the installation of this device.
