Description

Technical Field

[0001] The invention relates to the technical field of preparation or pretreatment of molding materials, and in particular to a device for preparing high-performance textile chemical fiber cloth. Background Art

[0002] Chemical fiber is a fiber with textile properties made from natural polymer compounds or synthetic polymer compounds as raw materials, through the processes of preparing spinning solution, spinning and post-treatment; in the spinning process, the spinneret can transform the viscous polymer melt or solution into fine streams through the spinneret hole, and these fine streams can be solidified by the coagulation medium to form a tow. The spinneret is often used in the production of synthetic fibers. In the production process of synthetic fibers, the molten polyester melt enters the spinning box through the conveying pipe, and then is extruded through the spinneret in the spinning box to form a tow, and then the tow is cooled by the coagulation medium, and finally the tow is wound into shape, thus completing the production of synthetic fibers. However, the existing spinning box cannot intercept and clean impurities, and the impurities in the spinning box are easily squeezed to the spinneret hole, resulting in partial or complete blockage of the spinneret hole, which makes it difficult to extrude the polyester melt, and the produced tows are inconsistent in thickness or easy to break, so that the synthetic fiber is of low quality.

[0003] In view of the above problems, the prior art has proposed some solutions. For example, Chinese patent application number: CN202211293718.5 discloses an anti-blocking device for a chemical fiber spinneret. The present invention scrapes off impurities on the filter plate while the shovel plate moves downward close to the right side of the filter plate to avoid blockage of the filter plate; when the cleaning plate moves downward to the limit, each round rod corresponds to a spinneret hole, and then the cleaning plate is pulled to the left, thereby driving the round rod to move to the left and insert into the corresponding spinneret hole, and the round rod moves to the left to clean the impurities at the spinneret hole; when the shovel plate moves downward to scrape off impurities on the filter plate When the impurities are removed from the second through hole at the bottom, the impurities can be cleaned in time to avoid the accumulation of impurities and blockage in the support tube; the push rod moves downward and intermittently contacts the cleaning plate, so that the round rod moves intermittently to the left and inserts into the spinneret hole, thereby cleaning the impurities at the spinneret hole multiple times; by pulling the lever back and forth, the scraper is driven to move back and forth to scrape off the impurities at the bottom of the shovel plate, thereby avoiding the shovel plate moving upward and bringing the impurities back into the support tube; but when the above scheme is used to clean the spinneret after it is blocked, the existing material needs to be cut off for processing, resulting in the problem that the production equipment cannot work continuously.

[0004] Therefore, a high-performance textile chemical fiber cloth preparation device is proposed to solve the problem that when cleaning a spinneret after being blocked, the existing materials need to be cut off for processing, resulting in the production equipment being unable to work continuously. Summary of the invention

[0005] The purpose of the present invention is to provide a high-performance textile chemical fiber cloth preparation device to solve the problem that when cleaning the spinneret after being blocked, the existing materials need to be cut off for processing, resulting in the production equipment being unable to work continuously.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A high-performance textile chemical fiber cloth preparation device comprises an extruder, a die head and a spinneret, wherein the die head is mounted on the front end face of the extruder, the spinneret is mounted on the lower end face of the die head, an extrusion cavity is arranged in the die head, a plurality of spinneret holes are evenly distributed on the spinneret circumference, a driving assembly and a clearing assembly are arranged on the die head, a driving shell and a driving block are arranged on the driving assembly, the driving shell is mounted on the side of the die head, a driving cavity is opened in the driving shell, the driving cavity is communicated with the extrusion cavity, the driving block is slidably connected in the driving cavity, a plurality of clearing plates are arranged on the clearing assembly, and a plurality of clearing plates are evenly distributed circumferentially and slidably connected on the upper end face of the spinneret, when the spinneret hole is blocked by impurities, the pressure in the extrusion cavity will increase, the driving assembly drives the driving block to move by the pressure in the extrusion cavity, the clearing assembly drives the clearing plate to rotate circumferentially by the driving block, thereby avoiding the problem that the production equipment cannot work continuously when the spinneret is cleaned after being blocked, and ensuring the continuity of the production of the high-performance textile chemical fiber cloth preparation device.

[0008] Optionally, the drive component can be an electric motor, a pneumatic drive or a hydraulic drive. All of the above three drive components can drive the clearing plate. The electric motor realizes mechanical movement through the magnetic force generated by electric current in the electromagnetic field, but the electric motor requires an additional electronic control system for control; the pneumatic drive uses the energy of compressed air to drive mechanical movement, but the pneumatic drive requires regular inspection and maintenance of the air source, pipelines and valves; the hydraulic drive uses liquid (usually oil) to push the piston under pressure to generate movement, but during the use of the hydraulic drive, leakage of hydraulic oil may cause environmental pollution and reduced efficiency; therefore, the above three drive components are not preferred solutions of the present invention.

[0009] Preferably, the driving assembly includes a driving spring, a rack, a gear set and a gear ring, the driving spring is installed in the driving cavity, and the two ends of the driving spring are respectively connected to the driving block and the extruder, a driving groove is opened on the lower end surface of the driving shell, the rack is installed on the lower end surface of the driving block, and the rack is also slidably connected in the driving groove, the gear set is installed on the lower end surface of the driving shell, and an input end and an output end are provided on the gear set, the input end is meshed with the rack, and the output end is meshed with the gear ring, the gear ring is coaxially connected with the clearing assembly, the driving block transfers the pressure in the extrusion cavity to the gear ring, and drives the gear ring to rotate, thereby avoiding the problem that the spinneret is blocked and cannot be cleared, resulting in the spinneret being unable to spin normally, and ensuring the normal operation of the high-performance textile chemical fiber cloth preparation device.

[0010] Optionally, the clearing components include ultrasonic cleaning, chemical cleaning and gas purging, and all three components can clear the spinneret. Ultrasonic cleaning uses the cavitation effect generated by ultrasound in the liquid to form tiny bubbles. These bubbles generate strong impact force when they burst, thereby removing pollutants on the spinneret. However, the investment in ultrasonic cleaning equipment is relatively high, and cleaning fluid is required, which increases operating costs; chemical cleaning uses specific chemicals (such as acid or alkaline solutions) to dissolve deposits and blockages on the spinneret. However, chemical cleaning may cause corrosion to the spinneret material, and chemicals must be selected with caution; gas purging uses high-pressure gas to purge the spinneret to clear blockages in the hole. However, gas purging may cause small particles to scatter and cause secondary pollution, and the effect on stubborn blockages is limited. Therefore, the three clearing components are not preferred solutions of the present invention.

[0011] Preferably, the clearing assembly includes a clearing sleeve, which is installed between the die head and the spinneret, and multiple clearing plates are installed in the clearing sleeve, and the outer ends of the multiple clearing plates are connected to the inner wall of the clearing sleeve, the gear ring is coaxially connected to the clearing sleeve, multiple clearing plates are semi-arc-shaped, and the concave surfaces on the multiple clearing plates are consistent with the rotation direction of the clearing sleeve, thereby avoiding the problem that the spinneret is blocked and cannot be cleared, resulting in the spinneret being unable to spin normally, and ensuring the normal operation of the high-performance textile chemical fiber cloth preparation device.

[0012] Preferably, the clearing sleeve is provided with a plurality of clearing ports, and the clearing sleeve is rotatably connected with a plurality of bin doors, the installation positions of the plurality of bin doors respectively correspond to the side walls of the plurality of clearing ports, and return coil springs are installed at the rotational connections between the plurality of bin doors and the clearing sleeve. A collecting trough is also installed on the outer side wall of the clearing sleeve, and the plurality of clearing ports are all connected with the collecting trough, thereby avoiding the problem of excessive accumulation of impurities in the extrusion cavity, which causes the spinneret to be unable to spin normally, and ensures the normal operation of the high-performance textile chemical fiber cloth preparation device.

[0013] Preferably, an air pump is installed on the side of the extruder, and a traction sleeve is installed on the lower side of the spinneret. The inner diameter of the traction sleeve is larger than the outer diameter of the spinneret. An air outlet is provided on the traction sleeve, and the air outlet is connected to the air pump. An adjusting plate is installed at the air outlet, and an adjusting rod is installed on the adjusting plate. An adjusting groove is provided on the side wall of the drive shell, and one end of the adjusting rod close to the driving block is slidably connected in the adjusting groove and connected to the driving block, thereby avoiding the problem that the air volume of the air outlet cannot be controlled when the clearing plate clears the blockage of the spinneret, resulting in excessive traction force that tears the chemical fiber yarn, thereby ensuring the continuity of the production of the high-performance textile chemical fiber cloth preparation device.

[0014] Preferably, a ratchet, a pawl and a spring are further provided between the input end and the output end, the ratchet is rotatably connected to the drive housing, one end of the pawl is rotatably connected to the drive housing, and the other end is in contact with the ratchet, and the spring is installed between the pawl and the drive housing, thereby avoiding reversal of the driving force of the ring gear when the drive block returns, thereby reducing the cleaning effect of the clearing plate on the spinneret, and ensuring the cleaning effect of the clearing plate on the spinneret in the high-performance textile chemical fiber cloth preparation device.

[0015] Preferably, a threaded section is provided between the gear ring and the clearing sleeve, the gear ring and the clearing sleeve are connected by threads, and the threads between the gear ring and the clearing sleeve are right-handed, thereby avoiding the problem of a gap between the lower end surface of the clearing plate and the upper end surface of the spinneret, resulting in the inability to clean up the debris on the spinneret, thereby ensuring the clearing effect of the clearing plate in the high-performance textile chemical fiber cloth preparation device.

[0016] Preferably, the clearing plate and the spinneret are made of high-strength and high-toughness materials, including at least any one of tool steel, high-carbon alloy steel and quenched steel. The contact surface between the clearing plate and the spinneret is heat-treated. After processing, the hardness of the contact surface between the clearing plate and the spinneret is between 50 and 60HRC, which avoids the problem of long-term friction between the lower end surface of the clearing plate and the upper end surface of the spinneret when the clearing plate clears the spinneret, resulting in serious wear of the lower end surface of the clearing plate and the upper end surface of the spinneret, thereby ensuring the service life of the high-performance textile chemical fiber cloth preparation device.

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

[0018] 1. The present invention provides a driving assembly and a clearing assembly in the shell.

DETAILED DESCRIPTION

[0030] See also Figures 1 to 8 The present invention provides a high-performance textile chemical fiber cloth preparation device, and the technical solution is as follows:

[0031] A high-performance textile chemical fiber cloth preparation device comprises an extruder 1, a die head 2 and a spinneret 3, wherein the die head 2 is mounted on the front end surface of the extruder 1, the spinneret 3 is mounted on the lower end surface of the die head 2, an extrusion cavity 4 is arranged in the die head 2, a plurality of spinneret holes 5 are evenly distributed on the circumference of the spinneret 3, a driving component and a clearing component are also arranged on the die head 2, a driving shell 701 and a driving block 702 are arranged on the driving component, the driving shell 701 is mounted on the side of the die head 2, a driving cavity 703 is arranged in the driving shell 701, the driving cavity 703 is connected with the extrusion cavity 4, the driving block 702 is slidably connected in the driving cavity 703, a plurality of clearing plates 602 are arranged on the clearing component, and a plurality of clearing plates 602 are evenly distributed on the circumference and slidably connected to the upper end surface of the spinneret 3, when the spinneret holes 5 are blocked by impurities, the number of spinneret holes 5 that can pass through is reduced, resulting in an increase in the pressure in the extrusion cavity 4, at which time the driving block 702 is driven by the pressure in the extrusion cavity 4 to move away The cleaning assembly drives the cleaning plate 602 to rotate in a circle through the driving block 702. At this time, the lower end of the cleaning plate 602 will scrape off the impurities on the upper end of the spinneret 3. The driving assembly of this scheme uses the pressure generated in the extrusion chamber 4 to provide driving force and drives the cleaning plate 602 to keep the spinneret 5 clean. Since the cleaning plate 602 cleans the spinneret 3 in the extrusion chamber 4, there is no air in the extrusion chamber 4 at this time. When the cleaning plate 602 cleans the spinneret 3, the spinneret 3 scraped by the cleaning plate 602 will be refilled with the material in the extrusion chamber 4. At this time, the cutoff part of the material in the spinneret 5 will fit with the material in the extrusion chamber 4, thereby not affecting the continuous spinning of the spinneret 5, avoiding the problem that the production equipment cannot work continuously when the spinneret 3 is cleaned after being blocked, and ensuring the continuity of the production of the high-performance textile chemical fiber cloth preparation device.

[0032] See also Figures 1 to 6The driving assembly includes a driving spring 704, a rack 705, a gear set 706 and a gear ring 707. The driving spring 704 is installed in the driving chamber 703, and the two ends of the driving spring 704 are respectively connected to the driving block 702 and the extruder 1. A driving groove 708 is provided on the lower end surface of the driving shell 701. The rack 705 is installed on the lower end surface of the driving block 702, and the rack 705 is also slidably connected in the driving groove 708. The gear set 706 is installed on the lower end surface of the driving shell 701. An input end 709 and an output end 710 are provided on the gear set 706. The input end 709 is meshed with the rack 705, and the output end 710 is meshed with the gear ring 707. The gear ring 707 is coaxially connected with the clearing assembly. When the pressure in the extrusion chamber 4 increases, the driving block 702 will be affected by the pressure in the extrusion chamber 4 and move away from it. The drive spring 704 will be compressed and contracted when the drive block 702 moves, and the rack 705 will also move with the drive block 702 during the movement of the drive block 702, and transmit the pressure to the input end 709. At this time, the output end 710 will generate a rotational force and drive the clearing plate 602 to rotate in a circle, thereby avoiding the problem that the spinneret 3 is blocked and cannot be cleared, resulting in the spinneret 3 being unable to spin normally, thereby ensuring the normal operation of the high-performance textile chemical fiber cloth preparation device. At the same time, the driving component of this solution uses the pressure in the extrusion chamber 4 to provide a driving force and drives the clearing plate 602, thereby reducing the investment cost of the equipment. The driving force that drives the clearing plate 602 to rotate changes with the change of the internal pressure of the extrusion chamber 4, and no additional investment in the electronic control system is required, thereby reducing the cost investment.

[0033] It is worth noting that a traction sleeve 806 is installed on the lower side of the spinneret 3, the inner diameter of the traction sleeve 806 is larger than the outer diameter of the spinneret 3, an air port 807 is provided on the traction sleeve 806, and the air port 807 is connected to the air pump 805. The air pump 805 is installed on the side of the extruder 1, and an adjustment plate 808 is installed at the air port 807. An adjustment rod 809 is installed on the adjustment plate 808. An adjustment groove 810 is provided on the side wall of the drive shell 701, and one end of the adjustment rod 809 close to the drive block 702 is slidably connected in the adjustment groove 810. When the pressure in the extrusion chamber 4 increases, The driving block 702 will be moved in the direction away from the extrusion chamber 4 by the pressure in the extrusion chamber 4. At this time, the adjusting rod 809 connected to the driving block 702 will drive the adjusting plate 808 to move in the direction of the air outlet 807. At this time, the adjusting plate 808 will control the opening size of the air outlet 807. The pressure in the extrusion chamber 4 will be inversely proportional to the air volume of the exhaust port 807. This avoids the problem that when the clearing plate 602 clears the blockage of the spinneret 3, the air volume of the air outlet 807 cannot be controlled, resulting in excessive traction and breaking the chemical fiber yarn, thereby ensuring the continuity of the production of the high-performance textile chemical fiber cloth preparation device.

[0034] It is also worth noting that a ratchet 901, a pawl 902 and a reed 903 are provided between the input end 709 and the output end 710. The ratchet 901 is rotatably connected to the drive housing 701. One end of the pawl 902 is rotatably connected to the drive housing 701 and the other end is in contact with the ratchet 901. The reed 903 is installed between the pawl 902 and the drive housing 701. When the drive block 702 is driven by the pressure of the extrusion chamber, the ratchet 901, the pawl 902 and the reed 903 will transmit the pressure to the output end 710 through the input end 709. When driven by the rebound pressure of the driving spring 704, the ratchet 901, the pawl 902 and the reed 903 will stop the pressure transmitted from the input end 709 to the output end 710, and lock the pressure on the output end 710. At this time, the pressure on the clearing sleeve 601 will cause the clearing sleeve 601 to rotate in a fixed direction, avoiding the reversal of the driving force of the ring gear 707 when the driving block 702 returns, thereby reducing the cleaning effect of the clearing plate 602 on the spinneret 3, and ensuring the cleaning effect of the clearing plate 602 on the spinneret 3 in the high-performance textile chemical fiber cloth preparation device.

[0035] See also Figures 1 to 8 The clearing assembly includes a clearing sleeve 601, which is installed between the die head 2 and the spinneret 3. Multiple clearing plates 602 are installed in the clearing sleeve 601, and the outer ends of the multiple clearing plates 602 are connected to the inner wall of the clearing sleeve 601. The gear ring 707 is coaxially connected to the clearing sleeve 601. The multiple clearing plates 602 are semi-arc-shaped, and the concave surfaces on the multiple clearing plates 602 are consistent with the rotation direction of the clearing sleeve 601. Since the clearing plates 602 are semi-arc-shaped, when the clearing plates 602 are driven by the driving assembly, the clearing plates 602 will rotate in the direction of the concave surface. At this time, the semi-arc-shaped clearing plates 602 will guide the impurities collected during the rotation process to the inner circle direction of the clearing sleeve 601, thereby avoiding the problem that the spinneret 3 is blocked and cannot be cleared, resulting in the spinneret 3 being unable to spin normally, thereby ensuring the normal operation of the high-performance textile chemical fiber cloth preparation device.

[0036] It is worth noting that a plurality of clearing ports 801 are provided on the clearing sleeve 601, and a plurality of bin doors 802 are rotatably connected to the clearing sleeve 601. The installation positions of the plurality of bin doors 802 correspond to the side walls of the plurality of clearing ports 801 respectively. Return coil springs 803 are installed at the rotational connection between the plurality of bin doors 802 and the clearing sleeve 601. A collecting trough 804 is also installed on the outer wall of the clearing sleeve 601. The plurality of clearing ports 801 are all connected to the collecting trough 804. When the clearing plate 602 guides the impurities collected during the rotation process toward the inner circle of the clearing sleeve 601, Due to the semi-arc setting of the clearing plate 602, the pressure during the rotation process of the clearing plate 602 will be transmitted from the inside to the outside along the arc surface in the rotation direction of the clearing plate 602. At this time, the collected impurities will squeeze the bin door 802. When the extrusion force of the impurities reaches the set value, the return coil spring 803 will be pressed to rotate toward the collecting trough 804. At this time, the impurities will be discharged from the extrusion cavity through the clearing port 801, avoiding the accumulation of too many impurities in the extrusion cavity 4, resulting in the problem that the spinneret 3 cannot spin normally, thereby ensuring the normal operation of the high-performance textile chemical fiber cloth preparation device.

[0037] It is also worth noting that a threaded section 904 is provided between the gear ring 707 and the clearing sleeve 601, the gear ring 707 and the clearing sleeve 601 are connected by threads, and the threads between the gear ring 707 and the clearing sleeve 601 are right-handed. When the gear ring 707 transmits pressure to the clearing sleeve 601, due to the setting of the threaded section 904, the pressure transmitted by the gear ring 707 to the clearing sleeve 601 will be decomposed into upward and downward components through the threaded section 904. At this time, the clearing sleeve 601 will be subjected to a rotational pressure and a downward pressure, and the clearing sleeve 601 will be subjected to a rotational pressure and a downward pressure. The downward pressure of the blocking sleeve 601 makes the lower end face of the clearing plate 602 fit tightly with the upper end face of the spinneret 3. At the same time, since the gear ring 707 and the clearing sleeve 601 are rotatably connected to the die head 2 and the spinneret 3 respectively, the force applied by the output end 710 to the gear ring 707 will cause the clearing plate 602 to rotate continuously, avoiding the problem of a gap between the lower end face of the clearing plate 602 and the upper end face of the spinneret 3, which makes it impossible to clean up the debris on the spinneret 3, thereby ensuring the clearing effect of the clearing plate 602 in the high-performance textile chemical fiber cloth preparation device.

[0038] The clearing plate 602 and the spinneret 3 are made of high-carbon alloy steel. The contact surface between the clearing plate 602 and the spinneret 3 is heat-treated. After processing, the hardness of the contact surface between the clearing plate 602 and the spinneret 3 is 56HRC, which avoids the problem that the lower end surface of the clearing plate 602 and the upper end surface of the spinneret 3 rub against each other for a long time when the clearing plate 602 clears the spinneret 3, resulting in serious wear of the lower end surface of the clearing plate 602 and the upper end surface of the spinneret 3, thereby ensuring the service life of the high-performance textile chemical fiber cloth preparation device.

[0039] While working, see Figures 1 to 8When the high-performance textile chemical fiber cloth preparation device is working normally, the pressure in the extrusion chamber 4 is offset by the pressure of the driving spring 704. At this time, the driving block 702 will remain stationary, and the warehouse door 802 will also remain stationary under the influence of the return coil spring 803. When the spinneret hole 5 is blocked by impurities, the number of spinneret holes 5 that can pass through is reduced, resulting in an increase in the pressure in the extrusion chamber 4. At this time, the driving block 702 is driven by the pressure in the extrusion chamber 4 to move away from the extrusion chamber 4. At this time, the driving spring 704 will be compressed and contracted, and in the process of the driving block 702 moving, the rack 705 and the adjusting rod 809 will also move with the driving block 702, and the pressure on the rack 705 will be transmitted to the input end 709, and the adjusting rod 809 will be The pressure is transmitted to the adjustment plate 808. At this time, the adjustment plate 808 will control the opening size of the air outlet 807. The pressure in the extrusion chamber 4 will be inversely proportional to the air volume of the exhaust port 807. When the rotational force generated at the output end 710 drives the clearing plate 602 to rotate in a circle, the ratchet 901, the pawl 902 and the reed 903 will transmit the pressure to the output end 710 through the input end 709. When the driving block 702 is driven by the rebound pressure of the driving spring 704, the ratchet 901, the pawl 902 and the reed 903 will terminate the pressure transmitted from the input end 709 to the output end 710, and lock the pressure on the output end 710. At this time, the pressure on the clearing sleeve 601 will cause the clearing sleeve 601 to rotate in a fixed direction.

[0040] Furthermore, when the clearing plate 602 is driven by the pressure of the output end 710, the clearing plate 602 will rotate in the direction of the concave surface. At this time, the semi-arc-shaped clearing plate 602 will guide the impurities collected during the rotation process to the inner circle of the clearing sleeve 601. When the clearing plate 602 guides the impurities collected during the rotation process to the inner circle of the clearing sleeve 601, due to the semi-arc-shaped setting of the clearing plate 602, the pressure during the rotation process of the clearing plate 602 will be transmitted from the inside to the outside along the arc surface of the rotation direction of the clearing plate 602, and the impurities collected during the rotation process will be transmitted to the direction of the warehouse door 802. At this time, the collected impurities will squeeze the warehouse door 802. When the extrusion force of the impurities reaches the set value, the return coil spring 803 will be pressed to rotate in the direction of the collecting trough 804. At this time, the impurities will be discharged out of the extrusion cavity through the clearing port 801.

[0041] It is worth noting that when the ring gear 707 transmits pressure to the clearing sleeve 601, due to the setting of the threaded section 904, the pressure transmitted to the clearing sleeve 601 by the ring gear 707 will be decomposed into upward and downward components. At this time, the clearing sleeve 601 will be subjected to a rotational pressure and a downward pressure. The downward pressure of the clearing sleeve 601 makes the lower end face of the clearing plate 602 fit tightly with the upper end face of the spinneret 3.

[0042] A specific embodiment of the present invention is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above described embodiment.
