Description

Technical Field

[0001] The utility model belongs to the technical field of cellulose filtration, and particularly relates to a laser cutting device for filter cloth used in viscose cellulose filament spinning. Background Technique

[0002] In the viscose cellulose filament spinning process, the filter cloth is the core filtering component of the spinneret system of the spinning machine, and its performance and quality have a decisive impact on the spinning process. The cutting quality of the filter cloth not only affects the filtration uniformity of the spinning solution, but also directly affects the fineness consistency, mechanical properties and appearance quality of the filament finished product. As the last filtering barrier before the spinning solution enters the spinneret, the filter cloth can effectively intercept impurity particles with a diameter of 1-10 μm to ensure the purity of the spinning solution. In order to cut a large-area filter cloth into a suitable size for use in the filtering equipment, precise cutting operations are required for the filter cloth. However, it still has the following drawbacks in actual use:

[0003] To ensure the size uniformity of the filter cloth, it needs to be cut by a laser cutting device. The cutting is directly carried out through a mechanical cutting structure. During the cutting process of the filter cloth, a large amount of smoke and dust will be generated, and the smoke and dust are directly discharged into the air, causing environmental pollution, etc.;

[0004] Secondly, under the action of laser cutting, the edge of the filter cloth is cut. After cutting, the filter cloth needs to be output on the conveyor belt. However, during the output process of the filter cloth, due to its adhesion to the conveying structure, it is easy to be carried and move under the conveying structure during the output process. Content of the Utility Model

[0005] The purpose of the utility model is to provide a laser cutting device for filter cloth used in viscose cellulose filament spinning, which solves the problems of easy generation of smoke and dust pollution during the laser cutting of the filter cloth, and the cut filter cloth is easy to be carried to the bottom of the conveying structure during output.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a laser cutting device for filter cloth in viscose cellulose filament spinning, which includes a conveying assembly, a negative pressure chamber, a secondary of a first linear motor, and a secondary of a second linear motor. The conveying assembly includes a first electric roller, a second electric roller, and a honeycomb steel belt. The honeycomb steel belt is movably connected to the outside of the two first electric rollers. A second electric roller is arranged below one of the first electric rollers. A negative pressure chamber is arranged inside the honeycomb steel belt. The top of the negative pressure chamber is evenly provided with communication holes. The top of the honeycomb steel belt is provided with a secondary of a second linear motor. A primary of a second linear motor is movably connected inside the secondary of the second linear motor. Both ends of the primary of the second linear motor are fixed with a secondary of a first linear motor. A first linear motor primary penetrates and is movably connected inside both of the secondaries of the first linear motor. A reflecting mirror is fixed on one side of a secondary of the first linear motor close to the secondary of the second linear motor. During operation, the filter cloth is conveyed by the conveying assembly, and negative pressure is set in the negative pressure chamber to extract the dust generated by cutting. Through the cooperation of the secondary of the first linear motor and the primary of the first linear motor, the secondary of the second motor is driven to move for filter cloth cutting.

[0008] Further, the conveying assembly further includes a support plate. Both ends of each first electric roller are rotatably connected to the support plate. The second electric roller is rotatably connected between the support plates at both ends of the upper first electric roller above it and is arranged below the honeycomb steel belt. A brush sleeve in contact with the honeycomb steel belt is fixed on the circumferential side of the second electric roller. The first electric roller and the second electric roller are supported on the ground by the support plate.

[0009] Further, support bars are symmetrically fixed on both sides of the negative pressure chamber, and the support bars are arranged outside the honeycomb steel belt. The negative pressure chamber is supported on the ground by the support bars.

[0010] Further, a fixed pipe is fixedly connected to one side of the negative pressure chamber. A filter is fixedly connected to the end of the fixed pipe away from the negative pressure chamber. An air extraction pipe is fixedly connected to the end of the filter away from the fixed pipe. The air extraction pipe extracts air, so that during the process of extracting the air in the negative pressure chamber, it drives the movement.

[0011] Further, support columns are fixed at both ends of the primary of the first linear motor. A laser focusing lens barrel is fixed on one side of the secondary of the second linear motor. After the laser is focused by the laser focusing lens barrel, the filter cloth is cut.

[0012] Further, the laser focusing lens barrel is arranged on the side of the secondary of the second linear motor close to the reflecting mirror. And the reflection surface of the reflecting mirror forms an angle of forty-five degrees with the part between the secondary of the first linear motor 3 close to the secondary of the second linear motor in the top view, so as to reflect and transmit the external laser to the laser focusing lens barrel.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem of easy generation of soot pollution during the laser cutting of filter cloth by setting a conveying component and a negative pressure chamber. During the process of cutting the filter cloth, the air in the suction pipe is extracted by the suction device. At this time, the air in the negative pressure chamber is conveyed to the filter through the fixed pipe, and after being filtered in the filter, the air is discharged into the suction device through the suction pipe, and the negative pressure is formed in the negative pressure chamber, so that the soot is sucked into the negative pressure chamber from the communication holes, reducing the soot pollution generated during laser cutting.

[0015] The utility model solves the problem that the filter cloth after laser cutting is easily carried to the bottom of the conveying structure along with the output by setting a conveying component, a negative pressure chamber, a first linear motor secondary and a second linear motor secondary. When the filter cloth passes through the gap between the first electric roller and the second electric roller above the second electric roller, the rotation of the second electric roller drives the brush sleeve to rotate, sweeping the filter cloth attached to the honeycomb steel belt, preventing the filter cloth from moving to the lower part of the honeycomb steel belt along with the honeycomb steel belt when it is conveyed between the first electric roller and the second electric roller below the first electric roller, and ensuring that the filter cloth is smoothly output to the next processing equipment.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention. Specific embodiment 1

[0026] Please refer to Figure 1 、 2, 6. The utility model relates to a laser cutting device for filter cloth in viscose cellulose filament spinning, which comprises a conveying assembly 1, a negative pressure chamber 2, a secondary of a first linear motor 3 and a secondary of a second linear motor 4. The conveying assembly 1 includes an electric roller 101, an electric roller 1031 and a honeycomb steel belt 104. A honeycomb steel belt 104 is movably connected to the outside of the two electric rollers 101. During the operation of the electric roller 101, it drives the honeycomb steel belt 104 to move, and during the movement of the honeycomb steel belt 104, it drives the filter cloth to be cut to move. An electric roller 1031 is arranged below one of the electric rollers 101. The rotation directions of the electric roller 101 and the electric roller 1031 are the same to prevent the filter cloth from moving under the honeycomb steel belt 104. A negative pressure chamber 2 is arranged inside the honeycomb steel belt 104. The top of the negative pressure chamber 2 is evenly provided with communication holes 201. During the operation of the negative pressure chamber 2, a negative pressure is maintained inside, and the communication holes 201 at its top continuously absorb the dust generated by cutting the filter cloth on the honeycomb steel belt 104. A secondary of a second linear motor 4 is arranged on the top of the honeycomb steel belt 104. During the operation of the secondary of the second linear motor 4, it drives the laser focusing lens barrel 402 to move linearly. A primary of a second linear motor 401 is movably connected inside the secondary of the second linear motor 4. The primary of the second linear motor 401 provides support for the secondary of the second linear motor 4, and after being powered on, it drives the primary of the second linear motor 401 to move. Both ends of the primary of the second linear motor 401 are fixed with a secondary of a first linear motor 3. A primary of a first linear motor 301 is movably connected through both of the secondaries of the first linear motor 3. During the movement of the secondary of the first linear motor 3 after the primary of the first linear motor 301 is powered on, it drives the primary of the second linear motor 401 to move. A reflecting mirror 302 is fixed on one side of a secondary of the first linear motor 3 close to the secondary of the second linear motor 4. The reflecting mirror 302 reflects the laser irradiated from the outside to it after changing the direction by 90 degrees and reflects it into the laser focusing lens barrel 402.

[0027] Specifically, the conveying assembly 1 further includes a support plate 102. Both ends of each electric roller 101 are rotatably connected to a support plate 102, and the electric roller 1031 is rotatably connected between the support plates 102 at both ends of the upper electric roller 101 and is arranged below the honeycomb steel belt 104. A brush sleeve 103 in contact with the honeycomb steel belt 104 is fixed on the circumferential side of the electric roller 1031. The support plate 102 supports the electric roller 101 and the electric roller 1031 on the ground.

[0028] Furthermore, support bars 205 are symmetrically fixed on both sides of the negative pressure chamber 2, and the support bars 205 are arranged outside the honeycomb steel belt 104. The negative pressure chamber 2 is supported by the support bars 205 and stably arranged inside the honeycomb steel belt 104.

[0029] Further, one side of the negative pressure chamber 2 is fixedly communicated with a fixed pipe 202. One end of the fixed pipe 202 away from the negative pressure chamber 2 is fixedly communicated with a filter 203. One end of the filter 203 away from the fixed pipe 202 is fixedly communicated with an air extraction pipe 204. The fixed pipe 202 communicates the negative pressure chamber 2 and the filter 203, and one end of the air extraction pipe 204 away from the filter 203 is communicated with the input end of the air extraction device. During operation, the air in the negative pressure chamber 2 is extracted, conveyed to the fixed pipe 202 in the negative pressure chamber 2, passes through the filter 203, and is discharged into the air extraction device through the air extraction pipe 204.

[0030] The operation process of this embodiment is as follows: During operation, the filter cloth to be cut is conveyed by an external conveying device and moves onto the upper surface of the honeycomb steel belt 104. Start the two first electric rollers 101 to drive the honeycomb steel belt 104 to move, and move the filter cloth on the honeycomb steel belt 104 from away from the second electric roller 1031 towards the second electric roller 1031. After cutting, it is conveyed above the second electric roller 1031. When the filter cloth passes through the gap between the first electric roller 101 and the second electric roller 1031 above the second electric roller 1031, the rotation of the second electric roller 1031 drives the brush sleeve 103 to rotate, sweeping the filter cloth attached to the honeycomb steel belt 104 to prevent the filter cloth from moving below the honeycomb steel belt 104 when it is conveyed between the first electric roller 101 and the second electric roller 1031 below the first electric roller 101. Specific Embodiment Two

[0031] Please refer to Figures 1-5 , on the basis of Specific Embodiment One, support columns 303 are fixed at both ends of the primary of the first linear motor 301. A laser focusing lens barrel 402 is fixed on one side of the secondary of the second linear motor 4. The primary of the first linear motor 301 is supported on the ground by the support columns 303. After the laser reflected on the reflecting mirror 302 is transmitted into the laser focusing lens barrel 402, the laser is concentrated and cuts the filter cloth passing on the honeycomb steel belt 104.

[0032] Specifically, the laser focusing lens barrel 402 is arranged on the side of the secondary of the second linear motor 4 close to the reflecting mirror 302, and the reflection surface of the reflecting mirror 302 forms an angle of forty-five degrees with the angle between the secondary of the first linear motor 3 close to the secondary of the second linear motor 4 in the top view perspective, so that during operation, the laser irradiated on the reflecting mirror 302 is transmitted into the laser focusing lens barrel 402.

[0033] The operation process of this embodiment is as follows: During operation, when the conveying component 1 is working, the honeycomb steel belt 104 conveys the filter cloth. During the conveyance of the filter cloth, the secondary of the second linear motor 4 and the secondary of the first linear motor 3 are energized. The primary of the first linear motor 301 drives the primary of the second linear motor 401 to move in the same direction and at the same speed as the honeycomb steel belt 104. At the same time, the primary of the second linear motor 401 on the secondary of the second linear motor 4 drives the laser focusing lens barrel 402 to move linearly. At the same time, the laser is transmitted onto the reflecting mirror 302 and then into the laser focusing lens barrel 402, so that during operation, the laser irradiates the filter cloth on the honeycomb steel belt 104 to cut the filter cloth. After cutting, the primary of the first linear motor 301 and the secondary of the first linear motor 3 are restarted to move in the reverse direction to the initial position, and the above-mentioned working process is repeated to perform the cutting cycle of the filter cloth. At the same time, the air extraction device extracts the air in the air extraction pipe 204. At this time, the air in the negative pressure chamber 2 is conveyed through the fixed pipe 202 to the filter 203, and after being filtered in the filter 203, the air is discharged from the air extraction pipe 204 into the air extraction device, and the negative pressure chamber 2 becomes negative pressure, so that the soot is sucked into the negative pressure chamber 2 from the communication hole 201, reducing the soot generated during laser cutting.
