Description

Technical Field

[0001] The utility model relates to the technical field of polyester yarns, in particular to a spandex polyester coated yarn cutting machine. Background Art

[0002] The characteristic of polyester yarn is that it can withstand chemicals and frequent washing, reducing fading and discoloration of clothing. Therefore, hotel uniforms, stone-ground blue denim clothing, sportswear or children's clothing all use polyester yarn. When industrially producing polyester yarn, it is necessary to go through steps such as bobbin winding and cutting. At this time, a spandex polyester coated yarn cutting machine is needed.

[0003] According to a publicly disclosed wire cutting machine for polyester yarn production (Announcement No.: CN218593084U), the control button is started in the above application, and the electric lifting rod drives the sliding block, and the sliding block drives the wire cutting blade and the electric heating wire to move downward, and there are two groups of electric heating wires, which are respectively arranged on both sides of the wire cutting blade, so that the incision can be heat treated while cutting, so that the incision is melted and condensed, avoiding the occurrence of wire shedding and scattering. The structure is simple, easy to use and reasonably designed.

[0004] However, in actual use, after the polyester yarn is cut, the yarn needs to be manually tied to the winding roll before the next cutting can be carried out. When a large number of repeated cuttings are required, manual tying consumes a lot of manpower and time, which reduces the cutting efficiency of the cutting machine. In view of this, we propose a spandex polyester coated yarn cutting machine. Utility Model Content

[0005] The purpose of the utility model is to provide a spandex polyester coated yarn cutting machine to solve the problems raised in the above background technology.

[0007] An electric push rod, the electric push rod is fixedly connected to the end of the base plate, the output end of the electric push rod is fixedly connected to a rotating motor, the output end of the rotating motor is fixedly connected to a bidirectional screw rod, the outer wall of the bidirectional screw rod is threadedly connected to a slide seat, the outer wall of the slide seat is provided with an arc groove, and the outer wall of the slide seat is rotatably connected to a pulley;

[0009] A wire pressing assembly is provided inside the base, and the wire pressing assembly includes a connecting plate, which is hinged on the outer wall of the blade, and a spring is fixedly connected to one end of the connecting plate close to the blade, and the inner wall of the connecting plate is rotatably connected to a pressure wheel, and the outer wall of the pressure wheel is fixedly connected to a self-rotating gear, and the outer wall of the self-rotating gear is engaged with a transmission gear, and the outer wall of the transmission gear is fixedly connected to the wire pressing wheel.

[0010] Preferably, there are two groups of the wire pressing assemblies, which are mirror-imaged and distributed at both ends of the blade, so that when the blade moves downward, the wire pressing assemblies flatten the covering wires at both ends of the blade.

[0011] Preferably, the outer wall of the wire outlet block is provided with a through wire opening, the bottom plate is flush with the lower end of the wire opening, and the lower end of the wire blocking rod is flush with the upper end of the wire opening, so that the friction on the bent part of the coated wire is smaller, and the wire opening is consistent in size with the coated wire, so that the coated wire can pass through the wire opening straightly.

[0012] Preferably, a wire groove is provided on the outer wall of the wire wheel, and the output end of the wire motor is fixedly connected to the wire wheel, so that the wire wheel can be moved downward to guide the coated wire and guide the coated wire onto the wire take-up roller.

[0013] Preferably, the length of the connecting plate is greater than the length of the blade, and the spring is fixedly connected at one end away from the connecting plate, so that when the blade does not cut the coated wire, the pressure wheel contacts and rolls with the bottom plate, thereby causing the self-rotating gear to drive the transmission gear to rotate, causing the wire pressing wheel and the pressure wheel to turn in opposite directions.

[0014] Preferably, the upper end of the blade is fixedly connected to a cutting electric push rod, so that the blade can be pressed down to cut the coated wire. The upper end of the heater is fixedly connected to a heating electric push rod. The heater is located directly above the wire take-up roller.

[0015] Compared with the existing technology, the present invention provides a spandex polyester coated yarn cutting machine, which has the following beneficial effects:

[0016] 1. The spandex and polyester covered yarn cutting machine rotates the bidirectional lead screw by rotating the motor, so that the slides at both ends of the bidirectional lead screw approach each other, causing the slides to clamp the covered yarn. The electric push rod then drives the rotating motor to move, causing the slide to drive the covered yarn to move. When it moves below the wire wheel, the wire wheel presses down and contacts the covered yarn. The wire motor rotates the wire wheel, guiding the covered yarn to the top of the take-up roller, and then the covered yarn is fixed to the take-up roller through the heater, saving labor and time and improving the efficiency of the cutting machine.

[0017] 2. In the spandex polyester coated yarn cutting machine, when the blade is pressed down, the pressure wheel rolls on the bottom plate to rotate the autorotating gear. The rotation of the autorotating gear causes the transmission gear to drive the line pressing wheel to rotate, so that the rotation direction of the pressure wheel is opposite to that of the line pressing wheel. At this time, the line pressing wheel contacts the coated yarn, thereby moving the coated yarn away from the blade, making the coated yarn taut, making the coated yarn easier to cut, and improving the cutting efficiency of the cutting machine.

[0024] In one embodiment of the present utility model, an electric push rod 121 is fixedly connected to the end of the base plate 6, the output end of the electric push rod 121 is fixedly connected to a rotating motor 122, the output end of the rotating motor 122 is fixedly connected to a bidirectional screw rod 123, the outer wall of the bidirectional screw rod 123 is threadedly connected to a slide 124, the outer wall of the slide 124 is provided with an arc groove 125, and the outer wall of the slide 124 is rotatably connected to a pulley 126.

[0026] In one embodiment of the present utility model, a wire pressing assembly 13 is provided inside the base 1, and the wire pressing assembly 13 includes a connecting plate 131, which is hinged on the outer wall of the blade 11, and the end of the connecting plate 131 close to the blade 11 is fixedly connected to a spring 132, the inner wall of the connecting plate 131 is rotatably connected to a pressing wheel 133, the outer wall of the pressing wheel 133 is fixedly connected to a self-rotating gear 134, the outer wall of the self-rotating gear 134 is meshed with a transmission gear 135, and the outer wall of the transmission gear 135 is fixedly connected to a wire pressing wheel 136.

[0027] In addition, there are two groups of wire pressing assemblies 13, and the two groups of wire pressing assemblies 13 are mirror-imaged and distributed at both ends of the blade 11. When the blade 11 moves downward, the wire pressing assemblies 13 flatten the covering wires at both ends of the blade 11, making the covering wires tighter and less likely to loosen, thereby making the covering wires easier to cut.

[0028] In an embodiment of the present utility model, a wire opening is provided on the outer wall of the wire outlet block 5, the bottom plate 6 is flush with the lower end of the wire opening, and the lower end of the wire blocking rod 4 is flush with the upper end of the wire opening, so that the friction on the bent part of the coated wire is smaller, and the wire opening is consistent in size with the coated wire, so that the coated wire can pass through the wire opening straightly, which facilitates the tightening of the coated wire and makes the coated wire easier to cut.

[0029] In an embodiment of the present utility model, a wire groove is provided on the outer wall of the wire wheel 128, and the output end of the wire motor 129 is fixedly connected to the wire wheel 128, so that the wire wheel 128 can move downward to guide the coated wire, and guide the coated wire onto the take-up roller 9.
