Description

Technical Field

[0001] This invention relates to the field of chemical fiber technology, and in particular to a method for cutting chemical fiber tail yarns and a device for processing chemical fiber tail yarns. Background Technology

[0002] my country is a major producer and consumer of textiles. Chemical fibers and cotton are the most important basic raw materials for the textile industry. Polyester filament accounts for 80% of the total chemical fiber production, and the production capacity of my country's chemical fiber filament industry has been growing rapidly in recent years. In the production process of chemical fiber filaments, the filaments are wound onto a paper tube by a winding machine to form a filament cake. When the filament cake reaches the predetermined winding specifications, it is transferred from the winding machine to a doffing machine. The filament cake is generally cylindrical in shape. During the filament cake formation process, because the last loop of fiber cannot be tightly wound, the fiber at the end of the winding cake will form a tail filament. Existing methods for cutting chemical fiber tail filaments cannot effectively cut them, resulting in poor cutting results. Summary of the Invention

[0018] In one embodiment, the cutting device is a heating element disposed on the first clamping plate and used to thermally melt the tail wire bundle to separate the tail wire bundle from the main body of the wire cake.

[0033] Please see Figures 1 to 5 One embodiment of a method for cutting chemical fiber tail yarn includes the following steps:

[0034] S520. Gather the tail strands of the silk cake to form a tail strand bundle.

[0035] S540, Cut the tail wire bundle.

[0036] Understandably, by first gathering the tail strands of the yarn cake into a tail strand bundle and then cutting the tail strand bundle, the flying or drifting strands in the air can be effectively cut off, resulting in a good cutting effect for chemical fiber tail strands.

[0037] In one embodiment, please refer to Figures 1 to 5 Step S520 specifically includes:

[0038] S522, Drive the tail of the silk cake along the first direction X to the gathering plane 221.

[0039] S524. The tail wires within the gathering plane 221 are gathered along the second direction Y to form a tail wire bundle, wherein the first direction X and the second direction Y are set at an angle.

[0040] Understandably, by gathering the scattered filaments in the air to the gathering plane 221, and then gathering the filaments in the gathering plane 221 to form a filament bundle, the scattered filaments in the air can be effectively cut, thereby improving the cutting effect.

[0041] Furthermore, in step S540, the tail wire bundle is specifically heat-fused to break it from the main body of the wire cake. By heat-fused to break the tail wire bundle, the structure is simple and the cutting effect is good. It can also heat-fuse the tail wire bundle together to prevent the cut tail wire bundle from falling or flying again.

[0042] Please see Figures 1 to 5 One embodiment of the chemical fiber tail yarn processing equipment includes a frame 100, a gathering device 200 and a cutting device 300. The gathering device 200 is disposed on the frame 100 and is used to gather the tail yarns of the yarn cake to form a tail yarn bundle. The cutting device 300 is disposed on the frame 100 and is used to cut the tail yarn bundle.

[0043] Understandably, since the gathering device 200 can gather the tail filaments of the yarn cake into a tail filament bundle, and then the cutting device 300 can cut the tail filament bundle, the flying or drifting filaments in the air can be effectively cut off, and the cutting effect of chemical fiber tail filaments is good.

[0044] Specifically, the frame 100 includes a base plate 110, and the gathering device 200 is connected to the base plate 110 to install and fix the gathering device 200.

[0045] In one embodiment, please refer to Figures 1 to 5 The gathering device 200 includes a first gathering component 210 and a second gathering component 220. The first gathering component 210 is disposed on the frame 100 and is used to drive the tail of the yarn cake along the first direction X to the gathering plane 221 of the second gathering component 220. The second gathering component 220 is disposed on the frame 100 and is used to gather the tail of the yarn at the gathering plane 221 along the second direction Y to form a tail yarn bundle. The first direction X and the second direction Y are set at an angle.

[0046] Understandably, the first gathering component 210 gathers the tail strands of the yarn cake to the gathering plane 221, and the second gathering component 220 gathers the tail strands at the gathering plane 221 to form a tail strand bundle. Then, the cutting device 300 performs uniform cutting, which can cut the scattered flying or drifting strands in the air from all directions, further improving the cutting effect.

[0047] Preferably, the angle between the first direction X and the second direction Y is 90 degrees, which facilitates the installation of the first gathering component 210 and the second gathering component 220.

[0048] Specifically, the first gathering assembly 210 includes a first driving member 211 and a pressing rod 212. The pressing rod 212 extends in a direction parallel to the gathering plane 221. The first driving member 211 is connected to the pressing rod 212 and is used to drive the pressing rod 212 to move along a first direction X, so as to drive the tail of the yarn cake to the gathering plane 221 along the first direction X. This can press the chemical fiber tail in the plane of movement of the pressing rod 212 to the gathering plane 221, wherein the first direction X is set at an angle to the gathering plane 221. Preferably, the first direction X is set perpendicular to the gathering plane 221.

[0049] Furthermore, the first driving member 211 is connected to the pressing rod 212 via a telescopic rod 217. The first driving member 211 is a linear motor, which is positioned above the frame 100 and drives the pressing rod 212 to move closer to or away from the converging plane 221. In other embodiments, the first driving member 211 may also be connected to the pressing rod 212 via a chain or rack, etc.

[0050] Specifically, in this embodiment, an elastic pressure pad is provided at the connection between the pressure rod 212 and the gathering plane 221. When the pressure rod 212 moves along the first direction X to the elastic pressure pad, the elastic pressure pad deforms to absorb the pressure generated by the pressure rod 212 and extend the service life of the pressure rod 212.

[0051] In one embodiment, please refer to Figures 1 to 5 The first gathering component 210 also includes a first guide rail 213 and a second guide rail 214. The first guide rail 213 and the second guide rail 214 are arranged opposite to each other on the frame 100. The two ends of the pressing rod 212 are slidably connected to the first guide rail 213 and the second guide rail 214 respectively. By setting the first guide rail 213 and the second guide rail 214 at both ends of the pressing rod 212, the pressing rod 212 can be prevented from rotating during the movement, ensuring that the movement direction of the pressing rod runs smoothly in the expected direction.

[0052] Specifically, a first slider 215 is provided between the first guide rail 213 and the holding rod 212, and a second slider 216 is provided between the second guide rail 214 and the holding rod 212, so that the holding rod 212 can move smoothly between the first guide rail 213 and the second guide rail 214.

[0053] In one embodiment, please refer to Figures 1 to 5 The second gathering component 220 includes a second driving member 222, a first clamping plate 223 and a second clamping plate 224. The second driving member 222 is connected to at least one of the first clamping plate 223 and the second clamping plate 224 in a transmission connection, and is used to drive the first clamping plate 223 to move closer to or further away from the second clamping plate 224 so as to gather the chemical fiber tails.

[0054] Specifically, the second gathering component 220 also includes a fixed plate 225 and a movable plate 226. The surface of the fixed plate 225 forms a gathering plane 221. Multiple first clamping plates 223 are provided and are distributed at intervals along the second direction Y on the fixed plate 225. Multiple second clamping plates 224 are provided and are distributed at intervals along the second direction Y on the movable plate 226. Each first clamping plate 223 is arranged in a one-to-one correspondence with each second clamping plate 224.

[0055] It is understandable that multiple first clamping plates 223 and second clamping plates 224 are provided to reduce the distance between each first clamping plate 223 and each second clamping plate 224, thereby dividing the chemical fiber tails in the gathering plane 221 into multiple tail bundles and improving the cutting effect of the cutting device 300.

[0056] In this embodiment, the second driving member 222 is connected to the moving plate 226 and is used to drive the moving plate 226 to move along the second direction Y, so that the moving plate 226 can drive each second clamping plate 224 to move closer to each first clamping plate 223, so as to gather the tail filaments at the gathering plane 221 along the second direction Y to form a tail filament bundle. The second driving member 222 drives each first clamping plate 223 to move closer to or away from each second clamping plate 224, gathering the chemical fiber tail filaments to form a tail filament bundle, which is convenient for the cutting device 300 to cut. In other embodiments, the second driving member 222 can also be connected to the moving plate 226 through a chain and rack, etc.

[0057] In one embodiment, please refer to Figures 1 to 5 The cutting device 300 is a heating element located on the first clamping plate 223 and is used to thermally melt and cut the tail wire bundle, thereby separating the tail wire bundle from the main body of the wire cake. Specifically, the heating element is a heating plate or heating wire, etc.

[0058] Understandably, the first gathering component 210 and the second gathering component 220 gather the chemical fiber tails to the gathering plane 221, and then melt the chemical fiber tails through the heating element, so that the tail bundles are thermally fused together, preventing the tail bundles from scattering in the air to form flying or drifting fibers, ensuring the normal operation of production activities and improving production efficiency.

[0059] In one embodiment, please refer to Figures 1 to 5 The chemical fiber tail yarn processing equipment also includes a recycling device 400, which includes a recycling channel 410 and a negative pressure recycler 420. The absorption port of the recycling channel 410 is located near the gathering plane 221, and the negative pressure recycler 420 is located on the frame 100 and is connected to the recycling channel 410.

[0060] The recycling device 400 is installed on the frame 100, and the negative pressure recycling device 420 is installed at the end of the recycling channel 410. This facilitates the recycling and reprocessing of the cut chemical fiber tails, further preventing the tail bundles from scattering in the air and causing environmental pollution, which in turn affects the normal operation of the equipment.

[0061] Specifically, two negative pressure recovery units 420 are provided and symmetrically arranged on both sides of the convergence plane 221. By having the two negative pressure recovery units 420 work together, the recovery effect of the recovery device 400 can be further improved.

[0062] Furthermore, the gathering plane 221 includes a proximal side near the yarn cake and a distal side away from the yarn cake, with the second gathering assembly 220 located on the proximal side and the recovery device 400 located on the distal side. Positioning the cutting device 300 and the recovery device 400 on both sides of the second gathering assembly 220 makes the chemical fiber tail yarn processing equipment compact, facilitating the cutting and recovery of the tail yarn bundles within the gathering plane 221.

[0063] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
