Description

Technical Field

[0001] The present invention relates to the technical field of spinning machines, and more specifically, to a melt spinning machine for producing chemical fiber filaments. Background Art

[0002] Melt spinning machine is a machine used to produce synthetic fibers, mainly through the melt spinning method. Its working principle is to melt the polymer raw material into a spinning melt by heating, and then evenly extrude it to the spinneret through the spinning pump, and press it out through the fine holes of the spinneret to form a filament stream, and finally cool and solidify it into fiber in air or water. Melt spinning machine is mainly suitable for polymers with a melting point lower than the decomposition temperature, such as polyamide, polyester, polyolefin, etc. It is mainly used in the field of textile science and technology to conduct melt spinning experiments.

[0003] When the existing melt spinning machine is in use, after the spinning melt enters the spinning device, the spinning melt is evenly squeezed to the spinneret through the spinning device, and is pressed out through the spinneret to form a filament flow, and finally cooled and solidified into fibers through air or water. At the same time, a filter plate is arranged between the spinning device and the spinneret to filter out impurities in the spinning melt to prevent the impurities from affecting the quality of the produced fiber filaments. However, after the filter plate is used for a long time, the use effect of the filter plate will be greatly reduced. Therefore, the filter plate needs to be cleaned and replaced regularly. However, when cleaning and replacing the filter plate, it is first necessary to stop the melt spinning machine and remove the spinneret, and then take out the filter plate for cleaning and replacement, which wastes a lot of time and reduces the working efficiency of the melt spinning machine.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This scheme sets a switching component, first placing the new filter plate in a placement slot on one side, then manually moving the T-shaped block to drive the No. 1 slider to move in the direction of the spinning device, and at the same time drive the No. 2 slider to move, thereby driving the switching block to rotate in the rotating slot, and then rotating the new filter plate into the spinning device, and rotating the old filter plate out of the spinning device, so that the filter plate can be quickly replaced without stopping the melt spinning machine, thereby improving the working efficiency of the melt spinning machine.

[0019] (2) This solution sets a fixing component, and drives the No. 2 card block to be inserted into the No. 1 card slot through the No. 3 spring, thereby fixing the switching block inside the rotating slot. This can prevent the switching block from rotating automatically, so that the filter plate can be stably aligned with the channel in the spinning device, thereby ensuring that the filter plate can stably filter the spinning melt in the spinning device, thereby improving the use effect of the switching component.

[0020] (3) This solution sets up a release assembly. When the placement slot with the old filter plate is rotated to the position of the opening on one side, the two No. 2 trapezoidal sliders on one side are pushed to move into the No. 8 slide slot by the fixed block, and then the No. 1 trapezoidal slider is pushed to be inserted into the triangular slot by the connecting rod, thereby driving the No. 1 clamping block to be pulled out of the annular clamping slot, releasing the fixation of the filter plate, and then the old filter plate can be taken out manually, which reduces the practicality of the switching assembly.

[0046] like Figure 2 , Figure 3 , Figure 4 As shown, there are three placement grooves 56, and the three placement grooves 56 are evenly distributed in a circular shape, there are two through openings 54, and the two through openings 54 are located above the two placement grooves 56 away from the spinning device 2, the outer circular surface of the filter plate 57 is provided with an annular groove 510, and both sides of the inner circular surfaces of the three placement grooves 56 are provided with No. 1 slide grooves 58, and the two No. 1 slide grooves 58 are slidably connected with No. 1 blocks 59 inside, and the outer surfaces of the two No. 1 blocks 59 are provided with No. 1 springs 511 on the side away from the annular groove 510.

[0047] like Figure 5 , Figure 6 As shown, a first arc-shaped slide groove 512 is provided on one side of the outer circular surface of the installation box 51, and the upper end of the inner wall of the first arc-shaped slide groove 512 passes through the rotating groove 52, and a first slider 513 is slidably connected inside the first arc-shaped slide groove 512, and a T-shaped block 514 is fixedly connected to one side of the outer surface of the first slider 513, and three triangular grooves 518 evenly distributed in a circular shape are provided on the outer side of the lower surface of the switching block 53, and a second slide groove 515 is provided on the upper surface of the first slider 513, and a second slider 516 is slidably connected inside the second slide groove 515, and the upper end of the second slider 516 extends into the rotating groove 52, and a second spring 517 is provided on the lower surface of the second slider 516.

[0048] When in use, first add the polymer raw material into the screw extruder in the processing structure 11, and at the same time melt the polymer raw material into a spinning melt through a heating device, then add the spinning melt into the spinning device 2, and the spinning melt is evenly extruded into the spinning die 3 through the spinning device 2, and then the spinning melt is pressed out through the spinning die 3 to form a filament flow, and then the cold air device 4 is started to blow out cooling air to solidify the filaments into fibers, and finally the fiber filaments are wound up through the winding device 10.

[0049] A filter plate 57 is provided at the bottom of the spinning device 2, so that impurities in the spinning melt can be filtered out, thereby improving the quality of the fiber filaments. However, after the filter plate 57 has been used for a long time, the use effect of the filter plate 57 will be greatly reduced. Therefore, the filter plate 57 needs to be cleaned and replaced regularly. However, when cleaning and replacing the filter plate 57, the melt spinning machine needs to be stopped first, and then the spinneret is removed, and then the filter plate 57 is taken out for cleaning and replacement, which wastes a lot of time and reduces the working efficiency of the melt spinning machine. Therefore, a switching component 5 is provided. When the old filter plate 57 needs to be cleaned and replaced, the new filter plate 57 is first placed in the placement groove 56 through the opening 54 on the other side. , and the through hole 55 can facilitate the spinning melt to flow through the filter plate 57 and the through hole 55 into the wire outlet die 3, and then the T-block 514 is manually moved to drive the No. 1 slider 513 to move in the No. 1 arc-shaped slide groove 512, so that the No. 1 slider 513 moves in the direction of the spinning device 2, and at the same time drives the No. 2 slider 516 to move, and then the upper end of the No. 2 slider 516 is engaged with the triangular slot 518, driving the switching block 53 to rotate in the rotating slot 52, thereby rotating the new filter plate 57 into the spinning device 2, and rotating the old filter plate 57 out of the spinning device 2, so that the filter plate 57 can be quickly replaced, and there is no need to shut down the melt spinning machine, thereby improving the working efficiency of the melt spinning machine. At the same time, the old filter plate 57 rotates to the position of the opening 54 on one side, and then the old filter plate 57 is taken out for cleaning, so as to facilitate the reuse of the filter plate 57. And because the No. 1 slider 513 is slidably connected with the No. 2 slide groove 515, the No. 1 slider 513 can move up and down. At the same time, because the triangular slot 518 and the No. 2 slider 516 are engaged, when the No. 1 slider 513 moves in the direction of the spinning device 2, it can drive the switching rotating block 53 to rotate. When the No. 1 slider 513 moves in the direction away from the spinning device 2, it cannot drive the switching rotating block 53 to rotate. The No. 2 spring 517 can better drive the No. 2 slider 516 to move upward. At the same time, when the filter plate 57 is placed in the placement groove 56, the No. 1 spring 511 drives the No. 1 clamping block 59 to move to the outside of the No. 1 slide groove 58, so that the No. 1 clamping block 59 is stuck in the annular clamping groove 510, and the filter plate 57 can be stably fixed in the placement groove 56.

[0050] like Figure 2 , Figure 7 , Figure 8 As shown, a fixing component 6 is arranged between the rotating groove 52 and the switching block 53, and the fixing component 6 includes three evenly distributed No. 1 slots 61 opened on the inner circular surface of the switching block 53, and three evenly distributed No. 3 slide grooves 62 are opened on the inner side of the inner wall of the rotating groove 52, and the three No. 3 slide grooves 62 are all slidably connected with No. 2 blocks 63, and a No. 3 spring 64 is arranged at the end of the No. 2 block 63 away from the No. 1 slot 61.

[0051] like Figure 7 , Figure 8 As shown, No. 4 slide grooves 65 are provided on both sides of the inner walls of the three No. 3 slide grooves 62, and sliding rods 66 are fixedly connected on both sides of the outer circumferential surfaces of the three No. 2 blocks 63, and the sliding rods 66 are slidably connected to the No. 4 slide grooves 65, and No. 5 slide grooves 67 are provided at one end of the inner walls of the six No. 4 slide grooves 65, and a No. 6 slide groove 68 is commonly provided at the lower ends of the six No. 5 slide grooves 67, and trapezoidal slide plates 69 are slidably connected inside the six No. 5 slide grooves 67, and a No. 3 slider 610 is commonly fixedly connected at the lower ends of the six trapezoidal slide plates 69, and the No. 3 slider 610 is slidably connected to the No. 6 slide groove 68, and a straight rod 611 is fixedly connected to the upper surface of the No. 3 slider 610, and the upper end of the straight rod 611 passes through the upper surface of the installation box 51, and the lower end of the straight rod 611 passes through the No. 3 slider 610 and the lower surface of the installation box 51.

[0052] like Figure 8 , Fig. 9 , Fig.10 As shown, an automatic component 7 is arranged above the No. 3 slider 610, and the automatic component 7 includes a No. 4 spring 71 arranged on the upper surface of the No. 3 slider 610, and the straight rod 611 passes through the No. 4 spring 71, and a mounting groove 72 is opened on one side of the inner circular surface of the No. 6 slide 68, and a rotating baffle 73 is rotatably connected inside the mounting groove 72, and a No. 5 spring 74 is arranged on one side of the inner wall of the mounting groove 72, and a through groove 75 is opened on one side of the inner circular surface of the mounting groove 72, and one end of the through groove 75 extends to the inside of the No. 2 slide 515, and a straight plate 76 is slidably connected inside the through groove 75, and the lower end of the rotating baffle 73 is located between the straight plate 76 and the No. 5 spring 74, and a limiting groove 77 is opened on one side of both sides of the inner wall of the through groove 75, and limiting blocks 78 are slidably connected in the two limiting grooves 77, and the two limiting blocks 78 are fixedly connected to the straight plate 76.

[0053] In the above embodiment, a new filter plate 57 is placed in the placement groove 56, and the T-shaped block 514 is manually moved to drive the switching block 53 to rotate, so that the new filter plate 57 is rotated into the spinning device 2, and the old filter plate 57 is rotated out of the spinning device 2, so that the filter plate 57 can be quickly replaced. However, because the switching block 53 is rotatably connected to the rotating groove 52, the switching block 53 can automatically rotate in the rotating groove 52, so that when the switching block 53 drives the filter plate 57 to rotate into the spinning device 2, the filter plate 57 cannot be aligned with the channel in the spinning device 2, resulting in the filter plate 57 being unable to stably pass the spinning melt in the spinning device 2. filtration, thereby reducing the use effect of the switching component 5, therefore a fixing component 6 is provided, and the switching turn block 53 drives the filter plate 57 to rotate into the spinning device 2, when the filter plate 57 is aligned with the channel in the spinning device 2, the No. 2 clamping block 63 is driven to move in the No. 3 slide groove 62 by the No. 3 spring 64, so that the No. 2 clamping block 63 is inserted into the No. 1 clamping groove 61, and then the switching turn block 53 is fixed in the rotating groove 52, which can prevent the switching turn block 53 from rotating automatically, so that the filter plate 57 can be stably aligned with the channel in the spinning device 2, thereby ensuring that the filter plate 57 can stably filter the spinning melt in the spinning device 2, thereby improving the use effect of the switching component 5. When it is necessary to release the fixation of the switching block 53, pressing the lower end of the straight rod 611 drives the third slider 610 to move upward in the sixth slide groove 68, and at the same time drives the trapezoidal slide 69 to move upward in the fifth slide groove 67, thereby pushing the slide bar 66 to move in the fourth slide groove 65 away from the first slot 61, and then drives the second block 63 to move, so that the second block 63 is pulled out of the first slot 61, thereby releasing the fixation of the switching block 53, and by pressing the upper end of the straight rod 611, the trapezoidal slide 69 can be driven to move downward, so that the third spring 64 can push the second block 63 to move from the first slot 61.

[0054] In the above embodiment, the No. 2 card block 63 is pushed into the No. 1 card slot 61 by the No. 3 spring 64, and the switching rotating block 53 is fixed in the rotating slot 52. Then, by manually pressing the lower end of the straight rod 611, the trapezoidal slide 69 can be controlled to move upward to drive the No. 2 card block 63 to be pulled out of the No. 1 card slot 61, thereby releasing the fixation of the switching rotating block 53 and fixing the position of the No. 2 card block 63, thereby closing the fixing assembly 6. Then, by manually pressing the upper end of the straight rod 611, the trapezoidal slide 69 is controlled to move downward to release the fixation of the No. 2 card block 63, thereby opening the fixing assembly 6. However, the fixing assembly 6 cannot be opened in time manually, which reduces the use effect of the fixing assembly 6. Therefore, an automatic assembly 7 is provided. After closing the fixing assembly 6, when the No. 1 slider 513 is driven to move toward the spinning device 2 by the T-shaped block 514, the switching rotating block 53 is also driven to rotate, thereby replacing the filter plate 57. When the No. 1 slider 513 moves to the No. 1 arc slot After the filter plate 57 is replaced, the fixing assembly 6 can be started and the switching block 53 can be fixed, thereby improving the use effect of the fixing assembly 6. After the third slider 610 moves upward and exceeds the rotating baffle 73, the fifth spring 74 drives the rotating baffle 73 to rotate in the opposite direction, so that the upper end of the rotating baffle 73 rotates to the outside of the mounting groove 72, thereby fixing the position of the third slider 610 and preventing the fourth spring 71 from driving the third slider 610 to move downward.

[0055] like Figure 4 , Fig.11 , Fig.12 As shown, a release assembly 8 is provided on one side of the outer surface of the six No. 1 blocks 59, and the release assembly 8 includes a triangular groove 81 opened on one side of the outer surface of the No. 1 block 59, and a No. 7 slide groove 82 is opened on the inner wall of the No. 1 slide groove 58 near the triangular groove 81, and a No. 1 trapezoidal slider 83 is slidably connected inside the No. 7 slide groove 82, and one end of the No. 1 trapezoidal slider 83 is slidably connected to the triangular groove 81, and a connecting rod 86 is fixedly connected on the side of the outer surface of the No. 1 trapezoidal slider 83 away from the triangular groove 81, and one end of the connecting rod 86 passes through the outer cylindrical surface of the switching rotating block 53, and an annular slide groove 88 is opened on the inner cylindrical surface of the rotating groove 52, and one end of the connecting rod 86 is slidably connected to the annular slide groove 88, and a fixed block 89 is fixedly connected to the position of the inner wall of the annular slide groove 88 near the side opening 54.

[0056] like Fig.11 , Fig.12 As shown, a No. 8 slide groove 84 is provided at a position corresponding to the No. 7 slide groove 82 on the outer circumferential surface of the switching block 53, a No. 2 trapezoidal slider 85 is slidably connected inside the No. 8 slide groove 84, and a connecting rod 86 is fixedly connected to the No. 2 trapezoidal slider 85, and a No. 6 spring 87 is provided on one side of the outer circumferential surface of the connecting rod 86 close to the No. 2 trapezoidal slider 85.

[0057] In the above embodiment, the switching block 53 is driven to rotate by moving the T-shaped block 514, so that the new filter plate 57 is rotated into the spinning device 2, and the old filter plate 57 is rotated out of the spinning device 2, and then the old filter plate 57 is taken out through the opening 54 on one side, thereby completing the replacement of the filter plate 57. However, because the filter plate 57 is inserted into the annular groove 510 through the No. 1 clamping block 59, the filter plate 57 is fixed inside the placement groove 56 and the filter plate 57 cannot be taken out, which reduces the practicality of the switching component 5. Therefore, a release component 8 is provided. When the placement groove 56 with the old filter plate 57 rotates to the position of the one side opening 54, the two No. 2 trapezoidal sliders 85 close to the one side opening 54 simultaneously rotate to the position of the fixed block 89 inside the annular slide groove 88. The second trapezoidal slider 85 on one side is pushed to move into the eighth slide groove 84 through the fixing block 89, and then the first trapezoidal slider 83 is pushed to move in the seventh slide groove 82 through the connecting rod 86, so that the first trapezoidal slider 83 is inserted into the triangular groove 81, thereby driving the first clamping block 59 to be drawn out from the annular clamping groove 510 and moved into the first slide groove 58, thereby releasing the fixation of the filter plate 57, and then when the placement groove 56 of the old filter plate 57 is rotated to the position of the side opening 54, the two first clamping blocks 59 in the placement groove 56 are simultaneously drawn out from the annular clamping groove 510, thereby releasing the fixation of the filter plate 57 in the placement groove 56, and then the old filter plate 57 can be taken out manually, which reduces the practicality of the switching component 5. When the No. 2 trapezoidal slider 85 rotates inside the annular groove 88 to leave the position of the fixed block 89, the No. 2 trapezoidal slider 85 is driven to move into the annular groove 88 by the No. 6 spring 87, and at the same time, the No. 1 trapezoidal slider 83 is driven to be pulled out of the triangular groove 81 by the connecting rod 86, so that the No. 1 clamping block 59 can move into the annular clamping groove 510.

[0058] like Figure 3 , Fig.13 , Fig.14As shown, the lower end of the inner wall of the No. 1 arc-shaped slide 512 is provided with an ejection assembly 9, and the ejection assembly 9 includes a No. 2 arc-shaped slide 91 opened with the lower end of the inner wall of the No. 1 arc-shaped slide 512, and one end of the No. 2 arc-shaped slide 91 is provided with a No. 1 air cavity 92, and an extrusion block 93 is sealed and slidably connected inside the No. 1 air cavity 92, and an arc-shaped slider 94 is fixedly connected to one side of the outer surface of the extrusion block 93, and the arc-shaped slider 94 is slidably connected to the No. 2 arc-shaped slide 91, and a groove 95 is provided on the upper surface of the arc-shaped slider 94, and the No. 1 air cavity 92 is sealed and slidably connected to the inner wall of the No. 1 arc-shaped slide 91. The slider 513 is located inside the groove 95, and a connecting pipe 910 is opened on the side of the inner wall of the No. 1 air cavity 92 away from the extrusion block 93, and a No. 2 air cavity 96 is opened at the other end of the connecting pipe 910. The No. 2 air cavity 96 is located below the one side opening 54, and the No. 2 air cavity 96 is located directly below the through hole 55 in the one side opening 54. A No. 4 slider 97 is slidably connected inside the No. 2 air cavity 96, and an ejector rod 98 is evenly and fixedly connected to the upper surface of the No. 4 slider 97, and the ejector rod 98 passes through the lower surface of the inner wall of the rotating groove 52.

[0059] like Fig.14 As shown, an air outlet 99 is provided on the lower surface of the No. 4 slider 97 at a position directly below the ejector rod 98, and the upper end of the air outlet 99 extends into the ejector rod 98 and penetrates the outer cylindrical surface of the ejector rod 98, a No. 1 air vent 911 is provided at the upper end of one side of the inner cylindrical surface of the No. 2 air cavity 96, a No. 2 air vent 912 is provided on one side of the inner wall of the No. 1 air cavity 92 away from the connecting pipe 910, and one end of the No. 1 air vent 911 and the No. 2 air vent 912 both penetrate the outer cylindrical surface of the mounting box 51.

[0060] In the above embodiment, the two No. 2 trapezoidal sliders 85 near the one side opening 54 are pushed into the No. 8 slide groove 84 by the fixing block 89, and then the No. 1 trapezoidal slider 83 is pushed into the triangular groove 81 by the connecting rod 86, so that the No. 1 clamping block 59 is pulled out from the annular clamping groove 510, and the fixing of the filter plate 57 is released, and then the old filter plate 57 can be taken out manually. However, because the filter plate 57 is located inside the placement groove 56, it is difficult to manually remove the filter plate 57, thereby reducing the use effect of the release component 8. Therefore, a ejection component 9 is provided. When the placement groove 56 with the old filter plate 57 is rotated to the position of the one side opening 54, When the filter plate 57 in the placement groove 56 is fixed, the release component 8 is used to release the fixation, and then the No. 1 slider 513 is driven to move to a position away from the spinning device 2, and the No. 1 slider 513 moves in the groove 95, thereby pushing the arc slider 94 to move in the No. 2 arc slide groove 91, and then pushing the extrusion block 93 to move into the No. 1 air cavity 92, and pushing the air in the No. 1 air cavity 92 into the No. 2 air cavity 96 through the connecting pipe 910, thereby pushing the No. 4 slider 97 to move upward, and at the same time driving the ejection rod 98 to move upward, so that the filter plate 57 in the placement groove 56 can be ejected, thereby facilitating the removal of the filter plate 57, thereby improving the use effect of the release component 8. When the No. 4 slider 97 and the ejector rod 98 are completely moved to the top of the No. 2 air cavity 96, the air below the No. 4 slider 97 in the No. 2 air cavity 96 is discharged through the air outlet 99, reducing the air pressure below the No. 4 slider 97, causing the No. 4 slider 97 and the ejector rod 98 to move downward, and then the air above the No. 4 slider 97 can be discharged through the No. 1 vent hole 911, and the air can enter the No. 1 air cavity 92 through the No. 2 vent hole 912.

[0061] Instructions for use: When the filter plate 57 in the spinning device 2 needs to be replaced, the new filter plate 57 is placed in the placement groove 56 through the opening 54 on the other side, and the No. 1 clamping block 59 is clamped into the annular clamping groove 510, and the filter plate 57 is fixed in the placement groove 56. Then, the lower end of the straight rod 611 is manually pressed to control the trapezoidal slide plate 69 to move upward, and the position of the No. 2 clamping block 63 is fixed, thereby closing the fixing component 6, and then the T-shaped block 514 is moved to drive the No. 1 slider 513 to move, and the switching block 53 is driven to rotate, and the new filter plate 57 is rotated into the spinning device 2. The old filter plate 57 is rotated out of the spinning device 2, and then the automatic component 7 is started at the same time to release the fixation of the No. 3 slider 610, and the No. 3 slider 610 is driven downward by the No. 4 spring 71 to release the fixation of the No. 2 block 63, thereby opening the fixing component 6, fixing the switching block 53, and starting the releasing component 8 at the same time to release the fixation of the filter plate 57 in the placement groove 56 inside the side opening 54, and then drive the No. 1 slider 513 to move to a position away from the spinning device 2, and start the ejection component 9 at the same time to eject the filter plate 57 in the placement groove 56.
