Description

Technical field:

[0001] The invention relates to a polyester fiber winding device. Background technology:

[0002] Polyester fiber, commonly known as "terylene," is a synthetic fiber made by spinning polyester, a product of the polycondensation of organic dibasic acids and diols. PET fiber, abbreviated as PET, is a high molecular weight compound. Invented in 1941, it is currently the leading synthetic fiber. Its greatest advantages are its excellent wrinkle resistance and shape retention, as well as its high strength and elastic recovery.

[0003] During the preparation process of polyester fiber, it needs to be wound on a winding drum through a winding device. However, when the existing winding device is working, each time the winding drum is replaced, the polyester fiber often needs to be manually wound on the winding drum again before winding can begin, resulting in low work efficiency. Summary of the invention:

[0004] The present invention aims to improve the problems existing in the above-mentioned prior art. That is, the technical problem to be solved by the present invention is to provide a polyester fiber winding device with reasonable design and improved working efficiency.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a polyester fiber winding device, comprising a vertical support base, a turntable rotatably arranged in front of the vertical support base, a pair of winding inflatable shafts symmetrically distributed around the axis of the turntable are provided on the front side of the turntable, and a winding drum is provided on the outer side of the winding inflatable shaft, and a fiber pressing assembly is provided on the outer side of the rear end of each winding inflatable shaft.

[0006] Furthermore, the fiber pressing assembly includes a fiber pressing block, which is driven by a pressing cylinder to reciprocate along the radial direction of the winding drum.

[0007] Furthermore, the clamping drive component includes an annular track coaxially arranged on the outside of the winding inflatable shaft, and a movable slider arranged on the front side of the annular track. The interior of the annular track is coaxially provided with an annular track groove with a notch located at the front end, and the inner circumferential side surface of the annular track groove is provided with an annular rack; the rear end of the movable slider is provided with a transmission shaft extending into the annular track groove, and the transmission shaft is driven to rotate by a motor arranged inside the movable slider, and a transmission gear is installed at one end of the transmission shaft extending into the annular track groove, and the transmission gear is meshed with the annular rack, and the motor drives the rotation along the annular rack, so as to realize the movement of the movable slider along the annular track; the clamping cylinder is installed at the front end of the movable slider.

[0008] Furthermore, an electromagnet is provided at the bottom of the annular track groove at the upper left side of the wound inflatable shaft. When the transmission shaft moves in a circular motion to a position corresponding to the electromagnet, electricity is turned on to adsorb the transmission shaft; the annular track is driven by an electric push rod provided on its rear side to move in the forward and backward directions.

[0009] Furthermore, the fiber pressing block has an arc shape at one end close to the winding drum.

[0010] Furthermore, a fiber pre-tensioning assembly is provided above a pair of winding inflatable shafts, and the fiber pre-tensioning assembly includes a pressure wheel driven to rise and fall by a lifting assembly, and the pressure wheel is used to contact the filament bundle wound on the outside of the winding drum, and the pressure wheel is also driven by a moving assembly to move in the forward and backward directions.

The pressure wheel is arranged on the inner side of the inverted U-shaped mounting frame, and the axis of the pressure wheel extends in the left and right directions. The lifting cylinder drives the pressure wheel to rise and fall through the inverted U-shaped mounting frame.

[0012] Furthermore, the moving component is driven by a ball screw nut pair arranged along the front and rear directions, and the ball screw nut pair is installed at the upper end of the vertical support seat and is located above the turntable; the lifting cylinder is installed on the moving part of the ball screw nut pair, and the ball screw nut pair drives the lifting cylinder, the inverted U-shaped mounting bracket and the pressure wheel to move along the front and rear directions.

[0013] Furthermore, a pre-tightening spring that extends vertically is provided between the left and right ends of the horizontal section of the inverted U-shaped mounting frame and the central axis of the pressure wheel. The pre-tightening spring applies a downward elastic force to the central axis of the pressure wheel so that the pressure wheel always has a pre-tightening force on the fiber roll after contacting the fiber.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] like Figures 1 to 6As shown, the present invention provides a polyester fiber winding device, comprising a vertical support base 1, a turntable 2 rotatably arranged on the front side of the vertical support base 1, the axis of the turntable 2 extending in the front-to-back direction, and the turntable 2 is driven to rotate by a power motor installed inside the vertical support base 1, and a pair of winding inflatable shafts 3 symmetrically distributed around the axis of the turntable are provided on the front side of the turntable 2, the axes of the winding inflatable shafts extending in the front-to-back direction, and each winding inflatable shaft 3 is driven to rotate by a winding motor arranged in the turntable; a winding drum 4 is provided on the outer side of the winding inflatable shaft 3, and the winding inflatable shaft drives the winding drum to rotate, and a fiber pressing assembly 5 is provided on the outer side of the rear end of each winding inflatable shaft 3, and the fiber pressing assembly 5 presses the filament bundle 6 onto the outer surface of the winding drum 4 along the radial direction of the winding drum 4, and the fiber pressing assembly 5 is driven by the pressing driving member to rotate synchronously with the winding inflatable shaft 3. By equipping each winding air shaft with a fiber pressing assembly, the filament bundle can be automatically wound on the winding drum when the winding drum is replaced, eliminating the need for manual winding operations and effectively improving work efficiency.

[0030] When winding:

[0031] Step S1: A winding drum 4 is placed on the outside of each winding inflatable shaft 3, and the polyester fiber 6 extended from the drafter is wound on the winding drum 4 located on the outside of the winding inflatable shaft 3 above;

[0032] Step S2: The winding air shaft 3 located above drives the winding drum 4 to rotate and starts winding the tow;

[0033] Step S3: During the winding process, the fiber pre-tightening assembly 5 is pressed down and contacts the polyester fiber on the winding drum 4, and the fiber pre-tightening assembly 5 moves along with the winding position of the tow;

[0034] Step S4: After the winding drum 4 is wound by the upper winding air shaft 3, the turntable 2 rotates to swap the positions of the upper and lower winding air shafts 3. The polyester fiber now winds around the upper winding air shaft 3. The fiber pressing assembly 5 of the upper winding air shaft 3 presses the yarn bundle, and then the yarn bundle between the upper and lower winding air shafts 3 is cut.

[0035] Step S5: The fiber pressing assembly 5 of the upper winding air shaft 3 keeps pressing the polyester fiber. Then, the upper winding air shaft 3 starts to drive the winding drum 4 to rotate. The fiber pressing assembly 5 rotates synchronously with the winding air shaft 3 to wind the yarn tow around the winding drum 4 on the winding air shaft 3.

[0036] Step S6: After the filament bundle in step S5 is wound on the winding drum 4 for a certain distance, the fiber pressing assembly 5 is separated from the winding drum 4, and the winding drum 4 continues to wind the filament bundle.

[0037] In this embodiment, the fiber pressing assembly 5 includes a fiber pressing block 7, which is driven by a pressing cylinder 8 to reciprocate radially along the winding drum. During operation, the pressing cylinder drives the fiber pressing block toward the surface of the winding drum, where it presses the tow against the outer surface of the winding drum.

[0038] In this embodiment, the clamping drive component includes an annular track 9 coaxially arranged on the outside of the winding inflatable shaft 3, and a movable slider 10 arranged on the front side of the annular track 9. The interior of the annular track 9 is coaxially provided with an annular track groove 11 with a notch located at the front end, and the inner circumferential side of the annular track groove 11 is coaxially provided with an annular rack 12; the rear end of the movable slider 10 is provided with a transmission shaft 13 extending into the annular track groove 11, and the transmission shaft 13 is driven to rotate by a motor (not shown in the figure) arranged inside the movable slider 10. A transmission gear 14 is installed at one end of the transmission shaft 13 extending into the annular track groove 11, and the transmission gear 14 is meshed with the annular rack 12. The motor drives the rotation along the annular rack, thereby realizing the movement of the movable slider along the annular track; the clamping cylinder is installed at the front end of the movable slider, and the movable slider drives the clamping cylinder and the fiber clamping block to move synchronously along the annular track. When the winding drum starts to wind the tow, the motor in the moving slider and the winding motor of the winding air shaft are started at the same time, so that the speed of the moving slider moving around the circular track is the same as the rotation speed of the winding air shaft, realizing the synchronous rotation of the fiber pressing block and the winding drum.

[0039] In this embodiment, an electromagnet 15 is provided at the bottom of the annular track groove 11 at the upper left side of the winding inflatable shaft 3. When the transmission shaft 13 moves in a circular motion along the annular track 9 to a position corresponding to the position of the electromagnet 15, the electromagnet 15 is energized to adsorb the transmission shaft 13, thereby fixing the position of the fiber pressing block.

[0040] In this embodiment, the annular track 9 is driven forward and backward by an electric push rod 16 located at its rear side, the rear end of which is mounted inside the turntable 2. After the initial winding of the tow is completed on the winding drum, the electric push rod drives the annular track backward, and the annular track drives the fiber pressing block to move synchronously. When the winding drum is replaced and the tow needs to be wound, the electric push rod drives the annular track forward, causing the fiber pressing block to move to a position corresponding to the rear end of the winding drum.

[0041] In this embodiment, in order to better fit with the outer surface of the winding drum, the fiber pressing block 7 is arc-shaped at one end close to the winding drum 4 .

[0042] In this embodiment, a fiber pre-tensioning assembly is provided above a pair of winding inflatable shafts 3. The fiber pre-tensioning assembly includes a pressure wheel 16 driven to rise and fall by a lifting assembly. The pressure wheel 16 is used to contact the filament bundle 6 wound on the outside of the winding drum 4. The pressure wheel 16 is also driven by a moving assembly to move in the forward and backward directions.

[0043] In this embodiment, the lifting assembly includes an inverted U-shaped mounting frame 17, which is driven to rise and fall by a lifting cylinder 18 vertically positioned directly above the inverted U-shaped mounting frame 17. The pressure roller 16 is positioned inside the inverted U-shaped mounting frame 17, with its axis extending in the left-right direction. The lifting cylinder 18 drives the pressure roller 16 up and down via the inverted U-shaped mounting frame 17. During the winding process, the lifting cylinder moves toward the winding drum via the inverted U-shaped mounting frame, bringing the pressure roller into contact with the tow. After winding is completed, the lifting cylinder moves away from the winding drum via the inverted U-shaped mounting frame.

[0044] In this embodiment, the moving component is driven by a ball screw nut pair 19 arranged along the front and rear directions. The ball screw nut pair 19 is installed at the upper end of the vertical support seat 1 and is located above the turntable; the lifting cylinder 18 is installed on the moving part of the ball screw nut pair 19, and the ball screw nut pair 19 drives the lifting cylinder 18, the inverted U-shaped mounting frame 17 and the pressure wheel 16 to move along the front and rear directions.

[0045] In this embodiment, a preload spring 20 that extends vertically is provided between the left and right ends of the horizontal section of the inverted U-shaped mounting frame 17 and the central axis of the pressure wheel 16. The preload spring 20 applies a downward elastic force to the central axis of the pressure wheel 16, so that the pressure wheel 16 always has a preload force on the tow roll after contacting the polyester fiber 6. Furthermore, an upper positioning cylinder 22 with an open bottom is provided at the left and right ends of the horizontal section of the inverted U-shaped mounting frame, and a lower positioning cylinder 23 with an open top is provided at the left and right ends of the central axis of the pressure wheel. The upper end of the preload spring extends into the upper positioning cylinder and is connected to the top of the upper positioning cylinder, and the lower end of the preload spring extends into the lower positioning cylinder and is connected to the bottom of the lower positioning cylinder, thereby achieving reliable installation of the preload spring.

[0046] During the winding process, as the diameter of the tow roll increases, the pressure wheel is pushed upward, and the preload spring on the upper end of the pressure wheel is compressed, ensuring that the pressure wheel always has a certain preload force on the tow roll, improving the winding tightness, avoiding the folding of the internal polyester fiber, and improving the winding quality; when the roll diameter is too large, the lifting cylinder drives the inverted U-shaped mounting frame to move upward, increasing the space above the preload spring to prevent the pressure wheel from excessively pressing the winding drum.

[0047] In this embodiment, the central axis of the pressure wheel 16 includes a middle cylindrical section and square sections at both ends, and the pressure wheel 16 can be rotatably installed on the cylindrical section; the left and right vertical sections of the inverted U-shaped mounting frame 17 are both provided with vertical rectangular slide grooves 21, and the vertical rectangular slide grooves 21 are convenient for the square section of the central axis of the pressure wheel 16 to pass through and form a sliding fit along the vertical direction, so as to guide the up and down movement of the pressure wheel.

[0048] In another embodiment, a polyester fiber preparation device is also included, such as Figure 7-11As shown, the polyester fiber preparation device includes a screw extruder 100, a spinning box 101, a cooling device 102, an oiling device 103, a yarn guide 104 and a stretching device 105 arranged in sequence from top to bottom. The screw extruder extrude and melt the granular raw material into a melt, and then send it to the spinning box. The metering pump metered and evenly distributed the melt to each spinning assembly, and the yarn bundle was extruded through the spinneret of the spinning assembly; the cooling device includes a cooling box 106, the top opening of the cooling box 106 is connected to the outlet of the spinning box 101. The wire ends are connected, and the bottom sealing plate is provided with a plurality of vertical through holes 107 to facilitate the passage of the wire bundle. The interior of the cooling box 106 is provided with a first cooling component 108, a second cooling component 109 and a third cooling component 110 from top to bottom. The first cooling component 108 is used to spray water mist on the wire bundle for cooling; the second cooling component 109 is used to cool the wire bundle by delivering cold air; the third cooling component 110 is used to cool the wire bundle by delivering normal temperature airflow, and the stretching device performs three-stage stretching on the wire bundle. The filament bundles extruded from the spinning box are cooled from top to bottom by spraying water mist, blowing cold air and blowing normal temperature air flow. The three different cooling methods are combined and the freshly extruded filament bundles are quickly cooled by spraying water mist, so that the properties and structure of the filament bundles are quickly stabilized and shaped; then they are cooled for the second time by cold air, which also has a good cooling effect. Finally, normal temperature air flow is used for blowing cooling. Since the water mist has quickly cooled the filament bundles, the subsequent cold air and normal temperature air flow cooling are not likely to increase the dryness rate due to uneven and unstable air flow. The overall cooling effect is good and the cooling efficiency is high.

[0049] The working process is:

[0050] Step S1: The screw extruder extrude and melt the pelletized raw materials into a melt, which is then sent to the spinning box. The metering pump evenly distributes the melt to each spinning assembly, and the filament bundle is extruded through the spinneret of the spinning assembly.

[0051] Step S2: The cooling device sequentially sprays water mist, blows cold air, and blows normal temperature air to cool the tow from top to bottom;

[0052] Step S3: The cooled tow is oiled by an oiling device;

[0053] Step S4: The oiled tow is subjected to three-stage stretching by a stretching device.

[0054] In this embodiment, the first cooling assembly 108 includes an annular spray pipe 111 installed on the inner wall of the cooling box 106. The inner wall of the spray pipe 111 is evenly distributed with multiple circles of first nozzles 112 along the vertical direction, and water mist is sprayed inward through the first nozzles.

[0055] In this embodiment, the second cooling component 109 includes a ring-shaped cold air delivery pipe 113 installed on the inner wall of the cooling box 106. The inner wall of the cold air delivery pipe 113 is evenly distributed with multiple circles of second nozzles 114 along the vertical direction, and cold air is sprayed inward through the second nozzles.

[0056] In this embodiment, the third cooling assembly 110 includes an annular normal temperature air flow conveying pipe 115 installed on the inner wall of the cooling box 106. The inner wall of the normal temperature air flow conveying pipe 115 is evenly distributed vertically with multiple circles of third nozzles 116, and normal temperature gas is sprayed inward through the third nozzles.

[0057] In this embodiment, the cooling box 106 is shaped like a truncated cone with a small diameter at the top and a large diameter at the bottom. The spray tube 111, the cold air delivery tube 113, and the normal temperature air flow delivery tube 115 are also shaped like a truncated cone with a small diameter at the top and a large diameter at the bottom. Multiple circles of first nozzles 112 are vertically distributed in a truncated cone shape on the inner wall of the spray tube 111. Multiple circles of second nozzles 114 are vertically distributed in a truncated cone shape on the inner wall of the cold air delivery tube 113. Multiple circles of third nozzles 116 are vertically distributed in a truncated cone shape on the inner wall of the normal temperature air flow delivery tube 115. The multiple circles of first nozzles, multiple circles of second nozzles, and multiple circles of third nozzles are designed to be distributed in a truncated cone shape to achieve a gradient distribution of cooling at each level. The advantage of this gradient distribution is that when the filaments are transported from top to bottom, the filaments are initially close to the nozzles, facilitating rapid cooling. Subsequently, the distance between the filaments and the nozzles gradually increases, which can reduce the impact on the filaments during cooling and prevent the filaments from shaking or even entanglement.

[0058] In this embodiment, the interior of the spinning box 101 is vertically divided into three cooling chambers 118 by a pair of upper and lower partitions 117. The first cooling assembly 108 is located in the topmost cooling chamber 118; the second cooling assembly 109 is located in the middle cooling chamber 118; and the third cooling assembly 110 is located in the bottommost cooling chamber 118. The partitions 117 are also provided with a plurality of vertical perforations to facilitate the passage of the filament bundles. The three cooling assemblies are respectively arranged in different cooling chambers to reduce mutual interference. The topmost cooling chamber is connected to a nitrogen inlet pipe above the first nozzle. Nitrogen is supplied into the cooling chamber via nitrogen inlet pipe 133, providing nitrogen protection and preventing the filament bundles from being oxidized by the supplied gas at high temperatures.

[0059] In this embodiment, the oiling device includes a pair of oiling rollers 119 distributed in the front and rear. The oiling rollers 119 are arranged horizontally and driven to rotate by an oiling motor 120 arranged on the right side thereof. The outer surface of each oiling roller 119 is provided with a plurality of annular oiling sponges 121 at intervals along its axial direction. The plurality of oiling sponges 121 correspond to the positions of a plurality of vertical perforations, and the filament bundle passes between the oiling sponges 121 at corresponding positions on the pair of oiling rollers. The oiling roller 119 is hollow, with an oil inlet pipe 122 connected to its left end. The outer surface of the oiling roller 119 is provided with multiple annular mounting grooves 123 along its axial direction. These grooves 123 correspond to the positions of multiple oiling sponges 121, which are installed within the corresponding annular mounting grooves 123. Each annular mounting groove 123 has an oil outlet 124 at its bottom to facilitate the flow of oil from the oiling roller 119. The oil inside the oiling roller flows out through the oil outlet holes and comes into contact with the oiling sponges. During operation, the oil inside the oiling roller flows out through the oil outlet holes and comes into contact with the oiling sponges, soaking the sponges. The sponges then come into contact with the filaments to achieve oiling. Because the filaments pass between the two oiling sponges located in front and back, the entire outer surface of the filaments comes into contact with the sponges, effectively improving the uniformity of the oiling.

[0060] In this embodiment, the oil inlet pipe is connected to an oil pump 125, the input end of which is connected to an oil storage tank. The oil in the oil storage tank is pumped into the oiling roller at high pressure by the oil pump. The oil in the oiling roller is pumped into the oiling roller at high pressure by the oil pump. The oil in the oiling roller is then sprayed into the oiling sponge in a high-pressure spray-like state, rapidly soaking the oiling sponge with the oil. This effectively prevents the tow from not being oiled or being insufficiently oiled due to excessively fast conveying speeds.

[0061] In this embodiment, an open-topped oil receiving trough 126 is located directly below each oiling roller 119. The sidewall of the oil receiving trough 126 is connected to the input end of the oil feed pump 125 via a circulation pipe 127. The oil receiving trough receives oil dripping from the oiling sponge, which is then returned to the oiling roller for recycling via the circulation pipe and the oil feed pump.

[0062] In this embodiment, the interior of the oiling roller 119 is evenly spaced along its axial direction with a plurality of electric heating plates 128. The oil is heated by the electric heating plates, and the overall viscosity and surface tension of the oil are reduced evenly, thereby making the spinning oiling uniform, better reducing the friction between the monofilaments and between the filaments and the guide elements, and preventing the generation of lint and static electricity.

[0063] In this embodiment, the stretching device includes three stretching boxes 129 arranged in sequence, each stretching box has a heating element, and each stretching box 129 is provided with a stretching roller group. The stretching roller group includes a turntable 130, and the turntable 130 is equipped with two stretching rollers 132 symmetrically distributed around the turntable axis. The filament bundle is wound in an S shape between the two stretching rollers, and the turntable drives the two stretching rollers to rotate to adjust the stretching tension.

[0064] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integrated molding using a casting process) (except where it is obviously impossible to use an integrated molding process).

[0065] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the present invention to express positional relationships or shapes include states or shapes that are approximate, similar, or close thereto.

[0066] Any component provided by the present invention may be assembled from multiple separate components, or may be a separate component manufactured by an integral molding process.
