Description

Technical Field

[0001] This invention relates to the field of chemical fiber production technology, specifically to a high-polymer polyester filament anti-breakage guiding clamping molding equipment. Background Technology

[0002] In the melt spinning process of chemical fibers, after the nascent filament bundle is extruded from the spinneret and cooled and solidified, it needs to go through intermediate processing steps such as bundling, guiding, and oiling before winding. This process allows the dispersed monofilaments to be gathered into a bundle and obtain a stable running path and a lubricated surface. It is a key transitional link connecting spinning and winding, and directly affects the subsequent winding quality and production continuity.

[0003] The molecular orientation of the polyester nascent filament bundle is not yet fully completed, resulting in low breaking strength. Furthermore, during the spinning process, factors such as extrusion pressure fluctuations and side-blowing disturbances can cause instantaneous peak tension in the filament bundle. At the same time, the contact and friction between the high-speed filament bundle and the guiding components can easily generate fuzz and static electricity. Without effective flexible clamping and lubrication measures, it is very easy to cause single filament breakage or even the entire bundle to break off, leading to production interruption.

[0004] In existing technologies, wire guides mostly use rigid ceramic parts or fixed wire guide hooks, and the clamping force is not adjustable, making it impossible to elastically buffer the tension peak. The guiding and oiling are separate stations, the wire path is long and the tension fluctuates greatly. The oiling amount is mostly constant and cannot be adjusted in conjunction with the clamping state, making it difficult to meet the lubrication needs and anti-wire breakage effect under different working conditions. Summary of the Invention

The oiling assembly is located inside the centering clamping plate. It can flexibly clamp the filament bundle while uniformly supplying oil to the filament bundle. It can also work with the auxiliary assembly to adjust the oil output, thereby achieving oiling of the filament bundle and lubrication and friction reduction of the contact surface.

After clamping and oiling, the filaments are smoothly discharged from the outlet and fed into the subsequent winding process, achieving integrated automatic filament centering, peak tension buffering, and uniform oiling, significantly reducing the rate of filament breakage and fuzzing during high-speed spinning.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0019] Therefore, the following detailed description of embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely illustrates some embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the embodiments of the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] The embodiments of the present invention are as follows: See Figure 1-7 As shown, a new polymer polyester filament anti-breakage guiding clamping molding equipment includes: a spinning and winding machine 1, a pair of connecting rods 11 fixedly installed on the spinning and winding machine 1, and a guide 12 fixedly installed at the end of the connecting rods 11 away from the spinning and winding machine 1. The guide 12 is composed of a guide ring 121 and a discharge port 122. The guide ring 121 is provided with a centering clamping device 2. The centering clamping plate 24 included in the centering clamping device 2 can work with the spring 23 to center and limit the cooling nascent filament bundle in a flexible manner, so as to realize the automatic centering of the filament bundle and buffer the peak tension. The oiling component 4 is located inside the centering clamping plate 24. It can flexibly clamp the filament bundle while uniformly supplying oil to the filament bundle. It can also work with the auxiliary component 5 to adjust the oil output, thereby achieving oiling of the filament bundle and lubrication and friction reduction of the contact surface. After cooling, the nascent filaments enter the guide member 12 and first pass through the centering clamping device 2 within the guide ring 121. The centering clamping plate 24, under the elastic action of the spring 23, forms a flexible, encircling clamp on the filaments, causing the filaments that have deviated from the center to automatically return to the central axis of the guide ring 121. When a momentary peak in tension occurs during spinning, the centering clamping plate 24 overcomes the elastic force of the spring 23 to retract, absorbing the impact energy, and then elastically resets after the tension subsides. Simultaneously, the oiling component 4, located within the centering clamping plate 24, uniformly supplies oil to the surface of the clamped filaments. The oil forms a lubricating film between the filaments and the clamping contact surface, reducing frictional resistance. The oil output can be adjusted in conjunction with the clamping state, matching the oiling amount to the filaments' operating conditions. After clamping and oiling, the filaments are smoothly discharged from the outlet 122 and fed into the subsequent winding process, achieving the integration of automatic filament centering, peak tension buffering, and uniform oiling, significantly reducing the rate of filament breakage and fuzzing during high-speed spinning.

[0023] See Figure 3 As shown, the centering clamping device 2 includes a set of guide rods 21 slidably installed in the guide ring 121. Each guide rod 21 is fixedly mounted with a top cover 22. A spring 23 is fixedly mounted on the top cover 22. The end of the spring 23 away from the top cover 22 is fixedly mounted on the guide ring 121. The end of the guide rod 21 away from the top cover 22 is connected to a centering clamping piece 24 through an adapter component 3. A guide head 25 is fixedly mounted on the centering clamping piece 24. The guide head 25 guides the wire bundle into the center channel. After the filament bundle enters the guide ring 121, it contacts the guide heads 25 on each centering clamping piece 24. The guide heads 25 guide the filament bundle into the central channel formed by the multiple centering clamping pieces 24. During normal operation, the spring 23 applies an elastic thrust to the guide rod 21 through the top cover 22. The guide rod 21 slides radially along the guide ring 121, pushing the centering clamping pieces 24 to close towards the center, forming a stable and flexible clamping of the filament bundle. When the tension of the filament bundle increases instantaneously, the radial reaction force of the filament bundle on the clamping pieces is transmitted to the top cover 22 through the guide rod 21, stretching the spring 23. This causes the guide rod 21 to move the centering clamping pieces 24 outward, increasing the passage space of the central channel and thus absorbing the tension peak. After the tension recovers, the spring 23 rebounds and pushes the guide rod 21 back to its original position, and the clamping force is restored accordingly. The adapter component 3 enables the centering clamping pieces 24 to adaptively deflect according to the posture of the filament bundle, avoiding rigid scraping.

[0024] See Figure 4 As shown, the guide head 25 includes a follower guide plate 252 fixedly mounted on the centering clamping plate 24, a memory metal plate 251 fixedly mounted on the follower guide plate 252, and the follower guide plate 252 provides an arc-shaped convergence guide surface; When the filament bundle enters the clamping area, it first contacts the follower guide plate 252. The arc-shaped surface of the follower guide plate 252 smoothly gathers the scattered monofilaments and guides them to the working surface of the centering clamping plate 24. The shape memory metal sheet 251 on the follower guide plate 252 undergoes curvature deformation when the spinning environment temperature changes: when the filament bundle temperature is high, the shape memory metal sheet 251 bends in a preset direction due to heat, reducing the contact curvature of the follower guide plate 252, thus lowering the contact wrap angle between the filament bundle and the guide surface, and consequently reducing frictional resistance, matching the condition of decreased filament strength at high temperatures; when the temperature drops, the shape memory metal sheet 251 restores its original curvature, the contact wrap angle increases, ensuring the stability of the clamping and guiding. The deformation of the shape memory metal sheet 251 is entirely driven by the ambient temperature, requiring no external energy supply; by utilizing the temperature-driven deformation characteristics of shape memory metal, the wrap angle of the guide contact surface automatically adapts to the temperature, automatically reducing friction and preventing filament breakage in the high-temperature zone, and maintaining stable clamping in the low-temperature zone, thus adapting to the spinning production of different materials.

[0025] See Figure 5 As shown, the adapter component 3 includes a rotating block 31 fixedly mounted on the centering clamping piece 24. The rotating block 31 is rotatably mounted inside the guide rod 21. An elastic piece 32 is fixedly mounted on the centering clamping piece 24. One end of the elastic piece 32 away from the centering clamping piece 24 is fixedly connected to the guide rod 21. The rotating block 31 provides the hinged deflection degree of freedom for the clamping piece. When the filament bundle experiences lateral deviation or attitude deflection during operation, the centering clamping plate 24 is subjected to the lateral force of the filament bundle. The rotating block 31 rotates relative to the guide rod 21, allowing the centering clamping plate 24 to deflect synchronously with the filament bundle's sway angle, preventing sharp-angle scraping between the clamping plate edge and the filament bundle. The elastic plate 32 provides elastic restoring force between the centering clamping plate 24 and the guide rod 21. When the filament bundle sway disappears, the elastic plate 32 pulls the centering clamping plate 24 back to its initial centering position, ensuring that the multiple clamping plates always symmetrically enclose the bundle. The elastic deformation of the elastic plate 32 also absorbs the vibration energy during the filament bundle sway process, making the deflection process of the clamping plate smooth and impact-free. This achieves real-time adaptive adjustment of the centering clamping plate 24 to the filament bundle's sway attitude, eliminating the risk of edge scraping.

[0026] See Figure 3 As shown, the oiling assembly 4 includes a storage cavity 43 opened in the centering clamping piece 24, the storage cavity 43 is filled with oil, and the centering clamping piece 24 is provided with capillary holes 44 communicating with the storage cavity 43. The storage cavity 43 stores the oil and provides a stable voltage environment. Under capillary force, the oil in the storage cavity 43 slowly seeps out through the capillary pores 44 on the working surface of the centering clamping plate 24, forming a uniform thin oil film on the contact surface between the clamping plate and the filament bundle. When the filament bundle passes through at high speed, the oil film transforms the direct contact between the filament bundle and the clamping plate into fluid lubrication contact, significantly reducing the coefficient of friction, reducing wear and fuzzing on the surface of the monofilament, and forming a continuous and stable lubricating film on the clamping contact surface through the oil seepage structure of the storage cavity 43 and the capillary pores 44, achieving simultaneous oiling and friction reduction.

[0027] See Figure 3 As shown, each storage cavity 43 is provided with a connecting pipe 42. The end of the connecting pipe 42 away from the storage cavity 43 is connected to an oil guide pipe 41. The oil guide pipe 41 collects and distributes external oil supply. An external oil supply system delivers oil to the oil guide pipe 41, which distributes the oil to each connecting pipe 42. The oil is then injected into the storage cavities 43 within each centering clamping piece 24 via the connecting pipes 42, ensuring synchronized oil levels and pressures across the storage cavities 43 of multiple clamping pieces. The oil guide pipe 41 serves as a common oil supply channel, guaranteeing consistent oil supply pressure across all storage cavities 43. This ensures uniform seepage from the capillaries 44 of each clamping piece, preventing uneven oil distribution on one side. When the level in a storage cavity 43 drops due to consumption, the oil in the oil guide pipe 41 is automatically replenished via the connecting pipes 42, maintaining dynamic balance across all storage cavities 43. The distributed oil supply network formed by the connecting pipes 42 and the oil guide pipe 41 ensures that the uniformity of oil distribution across multiple clamping pieces is unaffected by differences in individual piece consumption.

[0028] See Figure 4-5 As shown, an auxiliary component 5 is provided on the elastic sheet 32. The auxiliary component 5 includes an airbag 51 fixedly installed inside the elastic sheet 32. An air tube 52 is fixedly installed on the airbag 51. The air tube 52 is connected to the storage cavity 43. An air inlet 53 is provided on the airbag 51. A one-way valve is provided in both the air inlet 53 and the air tube 52. The airbag 51 is compressed and released as the elastic sheet 32 ​​deforms. When the centering clamping plate 24 deflects or retracts due to changes in the tension of the filament bundle, the elastic plate 32 undergoes elastic deformation, and the air bladder 51 fixed inside the elastic plate 32 is compressed or released. When the air bladder 51 is compressed, the internal air is forced into the storage cavity 43 through the air tube 52, increasing the air pressure in the storage cavity 43 and accelerating the seepage of the oil from the capillary pores 44, thus increasing the oil output. When the air bladder 51 is released, a negative pressure is formed inside, drawing in outside air through the air inlet 53. At the same time, the one-way valve in the air tube 52 closes to prevent the oil from flowing back into the storage cavity 43. The one-way valve in the air inlet 53 ensures that air can only enter the air bladder 51 in one direction, and the one-way valve in the air tube 52 ensures that air can only flow from the air bladder 51 to the storage cavity 43. Thus, each deformation of the elastic sheet 32 ​​drives the airbag 51 to complete one cycle of air intake and air compression, converting mechanical deformation into air pressure pulsation, adjusting the oil outlet pressure of the storage chamber 43 in real time, and realizing real-time linkage adjustment of the oil output according to the clamping state. When the tension is high, more oil is automatically supplied to enhance lubrication.

[0029] A pressure sensor is installed inside the airbag 51, and the pressure sensor is electrically connected to an external alarm. The airbag 51 is repeatedly compressed and released under the drive of the elastic sheet 32, and its internal air pressure changes dynamically with the clamping state. The pressure sensor monitors the air pressure value inside the airbag 51 in real time and transmits the air pressure signal to the external alarm. During normal spinning, the yarn bundle continuously applies tension to the clamping sheet, the elastic sheet 32 ​​maintains a certain deformation, and the air pressure inside the airbag 51 is maintained within the normal fluctuation range; when the yarn bundle breaks, the tension disappears instantly, the elastic sheet 32 ​​rebounds to the free state, the airbag 51 is completely released, and the internal air pressure drops sharply below the threshold. After the pressure sensor detects the abnormal low pressure signal, it triggers the external alarm to issue an audible and visual alarm.

[0030] See Figure 3 and 6 As shown, a recovery assembly 6 is provided on the guide ring 121. The recovery assembly 6 includes a recovery box 61 fixedly installed on the guide ring 121, a piston plate 62 slidably installed inside the recovery box 61, an electric push rod 64 fixedly installed on the recovery box 61, the output end of the electric push rod 64 being fixedly connected to the piston plate 62, a recovery pipe 63 fixedly installed on the recovery box 61, the recovery pipe 63 being connected to the oil guide pipe 41, a one-way valve being provided inside the recovery pipe 63, and the recovery box 61 providing an oil recovery storage space. Residual oil enters the recovery box 61 along the guide ring 121. The electric push rod 64 drives the piston plate 62 to slide inside the recovery box 61, creating a negative pressure inside the recovery box 61. This causes the oil in the recovery box 61 to flow back into the oil guide pipe 41 along the recovery pipe 63. The one-way valve in the recovery pipe 63 ensures that the oil can only flow from the recovery pipe 63 into the oil guide pipe 41, preventing backflow. After the piston plate 62 returns to its original position, the residual oil can flow normally into the recovery box 61.

[0031] See Figure 7 As shown, the discharge port 122 is flat and trumpet-shaped, which is used to smoothly discharge the filament bundle after it has been clamped and oiled, reduce the scraping friction when the filament bundle leaves the clamping mechanism, weaken the disturbance of the filament bundle boundary, and reduce the phenomenon of filament drift and single filament splitting at the outlet. After being centered, clamped, and oiled, the filaments enter the discharge port 122 from the guide ring 121. The discharge port 122 has a funnel-shaped structure that gradually increases in size. As the filaments pass through, the cross-section of the channel gradually expands, allowing the filaments to obtain a smooth spatial transition during the process of escaping the clamping constraints, thus providing a stable filament input for the subsequent winding process.

[0032] The overall working principle of this invention is as follows: After cooling, the nascent filament bundle enters the guide member 12 and first passes through the centering clamping device 2 within the guide ring 121. The centering clamping plate 24, under the elastic action of the spring 23, forms a flexible, surrounding clamp on the filament bundle, causing the filament bundle that has deviated from the center to automatically return to the central axis of the guide ring 121. When a momentary peak in tension occurs during the spinning process, the centering clamping plate 24 overcomes the elastic force of the spring 23 to yield, absorbing the impact energy, and then elastically resets after the tension subsides. Simultaneously, the oiling component 4, located within the centering clamping plate 24, uniformly supplies oil to the surface of the clamped filament bundle. The oil forms a lubricating film between the filament bundle and the clamping contact surface, reducing frictional resistance. The oil output can be adjusted in conjunction with the clamping state, matching the oiling amount to the filament bundle's operating conditions. After clamping and oiling, the filament bundle is smoothly discharged from the outlet 122 and sent to the subsequent winding process, achieving the integration of automatic filament bundle centering, peak tension buffering, and uniform oiling, significantly reducing the rate of filament breakage and fuzzing during high-speed spinning. After the filament bundle enters the guide ring 121, it contacts the guide heads 25 on each centering clamping piece 24. The guide heads 25 guide the filament bundle into the central channel formed by the multiple centering clamping pieces 24. During normal operation, the spring 23 applies an elastic thrust to the guide rod 21 through the top cover 22. The guide rod 21 slides radially along the guide ring 121, pushing the centering clamping pieces 24 to close towards the center, forming a stable and flexible clamping of the filament bundle. When the tension of the filament bundle increases instantaneously, the radial reaction force of the filament bundle on the clamping pieces is transmitted to the top cover 22 through the guide rod 21, stretching the spring 23. This causes the guide rod 21 to move the centering clamping pieces 24 outward, increasing the passage space of the central channel and thus absorbing the tension peak. After the tension recovers, the spring 23 rebounds and pushes the guide rod 21 back to its original position, and the clamping force is restored accordingly. The adapter component 3 enables the centering clamping pieces 24 to adaptively deflect according to the posture of the filament bundle, avoiding rigid scraping. When the filament bundle enters the clamping area, it first contacts the follower guide plate 252. The arc-shaped surface of the follower guide plate 252 smoothly gathers the scattered monofilaments and guides them to the working surface of the centering clamping plate 24. The shape memory metal sheet 251 on the follower guide plate 252 undergoes curvature deformation when the spinning environment temperature changes: when the filament bundle temperature is high, the shape memory metal sheet 251 bends in a preset direction due to heat, causing the contact curvature of the follower guide plate 252 to decrease, thus reducing the contact wrap angle between the filament bundle and the guide surface, and consequently reducing frictional resistance, matching the working condition of decreased filament strength at high temperatures; when the temperature drops, the shape memory metal sheet 251 restores its original curvature, the contact wrap angle increases, and the stability of the clamping and guiding is ensured. The deformation of the shape memory metal sheet 251 is entirely driven by the ambient temperature, requiring no external energy supply; by utilizing the temperature-driven deformation characteristics of the shape memory metal, the wrap angle of the guide contact surface automatically adapts to the temperature, automatically reducing friction and preventing filament breakage in the high-temperature zone, and maintaining stable clamping in the low-temperature zone, thus adapting to the spinning production of different materials; When the filament bundle experiences lateral deviation or attitude deflection during operation, the centering clamping plate 24 is subjected to the lateral force of the filament bundle. The rotating block 31 rotates relative to the guide rod 21, allowing the centering clamping plate 24 to deflect synchronously with the filament bundle's sway angle, preventing sharp-angle scraping between the clamping plate edge and the filament bundle. The elastic plate 32 provides elastic restoring force between the centering clamping plate 24 and the guide rod 21. When the filament bundle sway disappears, the elastic plate 32 pulls the centering clamping plate 24 back to its initial centering position, ensuring that the multiple clamping plates always symmetrically surround the bundle. The elastic deformation of the elastic plate 32 also absorbs the vibration energy during the filament bundle sway process, making the deflection process of the clamping plate smooth and impact-free. This achieves real-time adaptive adjustment of the centering clamping plate 24 to the filament bundle's sway attitude, eliminating the risk of edge scraping. Under the action of capillary force, the oil in the storage cavity 43 slowly seeps out through the capillary pores 44 on the working surface of the centering clamping plate 24, forming a uniform thin oil film on the contact surface between the clamping plate and the filament bundle.

An external oil supply system delivers oil to the oil guide pipe 41, which distributes the oil to each connecting pipe 42. The oil is then injected into the storage cavities 43 within each centering clamping piece 24 via the connecting pipes 42, ensuring synchronized oil levels and pressures across the storage cavities 43 of multiple clamping pieces. The oil guide pipe 41 serves as a common oil supply channel, guaranteeing consistent oil supply pressure across all storage cavities 43. This ensures uniform seepage from the capillary pores 44 of each clamping piece, preventing uneven oil distribution on one side.

When the air bladder 51 is released, a negative pressure is formed inside, drawing in outside air through the air inlet 53. At the same time, the one-way valve in the air tube 52 closes to prevent the oil from flowing back into the storage cavity 43. The one-way valve in the air inlet 53 ensures that air can only enter the air bladder 51 in one direction, and the one-way valve in the air tube 52 ensures that air can only flow from the air bladder 51 to the storage cavity 43. Thus, each deformation of the elastic sheet 32 ​​drives the airbag 51 to complete one cycle of air intake and air compression, converting mechanical deformation into air pressure pulsation, adjusting the oil outlet pressure of the storage chamber 43 in real time, and realizing real-time linkage adjustment of the oil output according to the clamping state. When the tension is high, more oil is automatically supplied to enhance lubrication. The airbag 51 is repeatedly compressed and released under the drive of the elastic sheet 32, and its internal air pressure changes dynamically with the clamping state. The pressure sensor monitors the air pressure value inside the airbag 51 in real time and transmits the air pressure signal to the external alarm. During normal spinning, the yarn bundle continuously applies tension to the clamping sheet, the elastic sheet 32 ​​maintains a certain deformation, and the air pressure inside the airbag 51 is maintained within the normal fluctuation range; when the yarn bundle breaks, the tension disappears instantly, the elastic sheet 32 ​​rebounds to the free state, the airbag 51 is completely released, and the internal air pressure drops sharply below the threshold. After the pressure sensor detects the abnormal low pressure signal, it triggers the external alarm to issue an audible and visual alarm. Residual oil enters the recovery box 61 along the guide ring 121. The electric push rod 64 drives the piston plate 62 to slide inside the recovery box 61, creating a negative pressure inside the recovery box 61. This causes the oil in the recovery box 61 to flow back into the guide pipe 41 along the recovery pipe 63. The one-way valve in the recovery pipe 63 ensures that the oil can only flow from the recovery pipe 63 into the guide pipe 41, preventing backflow. After the piston plate 62 returns to its original position, the residual oil can flow normally into the recovery box 61. After being centered, clamped, and oiled, the filaments enter the discharge port 122 from the guide ring 121. The discharge port 122 has a funnel-shaped structure that gradually increases in size. As the filaments pass through, the cross-section of the channel gradually expands, allowing the filaments to obtain a smooth spatial transition during the process of escaping the clamping constraints, thus providing a stable filament input for the subsequent winding process.
