A high-elasticity low-shrinkage elastic polyester yarn setting device

Abstract

This utility model relates to the field of polyester filament shaping, and more particularly to a shaping device for high-elasticity, low-shrinkage polyester filaments. Traditional yarn rollers are prone to swaying due to the influence of the take-up roller, which can cause the polyester filaments to get caught inside the device and break. During the winding process, different types of polyester filaments result in varying internal tensions, easily leading to breakage of filaments with lower tension. This utility model includes support legs, a base plate, and a shell. Several support legs are fixedly connected to the top of the base plate, and the shell is fixedly connected to the top of the base plate. This utility model, through the cooperation of a handle and a Π-shaped connecting plate, allows the Π-shaped connecting plate to move downwards, simultaneously moving a wedge block downwards. This disengages the round-headed rod from the wedge block's restraint, preventing the traditional yarn rollers from swaying due to the influence of the take-up roller and thus avoiding the polyester filaments getting caught inside the device and breaking.

Description

Technical Field

[0001] This utility model relates to the field of polyester yarn shaping, and in particular to a high-elasticity, low-shrinkage polyester yarn shaping device. Background Technology

[0002] Polyester filament setting is a key process in fiber production. Traditional setting devices mainly stabilize the polyester filament structure through heating and cooling. High-temperature treatment reduces the polyester filament's sensitivity to heat, making the set polyester filament less prone to wrinkling and able to recover its original shape more quickly, thus reducing shrinkage during subsequent processing or daily use.

[0003] In existing polyester filament setting devices, polyester filaments are usually threaded manually from inside the device to the outlet. The original filament rollers are easily affected by the take-up rollers and oscillate, which can cause the polyester filaments to get caught inside the device and break, greatly affecting work efficiency. Furthermore, during the winding process, different types of polyester filaments will result in different internal tensions, which can easily cause polyester filaments with lower tension to break.

[0004] Therefore, it is necessary to design a high-elasticity, low-shrinkage polyester yarn shaping device to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the shortcomings of the original yarn rollers and their susceptibility to oscillation caused by the take-up rollers, which would cause the polyester yarn to get caught inside the device and break, greatly affecting work efficiency, the following measures are needed: during the winding process, different types of polyester yarn will result in different internal tensions, which can easily cause the polyester yarn with lower tension to break.

The top of several support legs is fixedly connected to the base plate, and the shell is fixedly connected to the top of the base plate. It also includes a drive motor. The drive motor is installed on one side of the shell. The take-up rollers are rotatably connected to both sides of the inner wall of the shell. The output end of the drive motor passes through one side of the shell and is fixedly connected to the take-up roller. The top of the base plate is symmetrically fixedly connected to round shafts. The outer walls of the two round shafts are slidably connected to handles. The outer walls of the round shafts are fitted with first springs.

The two ends of the yarn roller are engaged with the convex round plate. The two sides of the handle are provided with clamping mechanisms for the yarn roller.

[0007] More preferably, the clamping mechanism includes a Π-shaped connecting plate, Π-shaped connecting plates fixed to both sides of the handle, a pressure plate symmetrically and slidably connected to the inner side of the Π-shaped connecting plate, a wedge block fixed to one side of the pressure plate, a second spring fixed to one side of the wedge block, one end of the second spring fixed to the Π-shaped connecting plate, and a concave circular plate rotatably connected to one side of the pressure plate.

[0008] More preferably, the clamping mechanism also includes a first connecting rod, with the first connecting rod fixed to both sides of the outer shell, and a buckle fixed to one side of the first connecting rod. A round-headed rod is engaged inside the buckle, and one end of the round-headed rod contacts the inclined surface of the wedge block.

[0009] More preferably, it also includes a second connecting rod, with two second connecting rods symmetrically fixed to the top of the handle. A square plate is fixed to one end of each of the two second connecting rods. A sliding groove is opened on one side of each of the two square plates. A sliding shaft is slidably connected in each of the two sliding grooves. A heating chamber is fixed to one end of each of the two sliding shafts. The bottom of the inner wall of the outer shell is slidably connected to the two heating chambers respectively. A rectangular through groove is opened on the bottom of both the outer shell and the bottom plate. A steam box is fixedly connected in the rectangular groove of the outer shell and the bottom plate, and the steam box is located directly below the two heating chambers.

[0010] More preferably, it also includes a first connecting plate, with two first connecting plates symmetrically fixed to one side of each of the two heating chambers, and a second connecting plate hinged to one side of each of the two first connecting plates. A hinge shaft is hinged to one end of each of the two second connecting plates, and the bottom of the hinge shaft is slidably connected to the outer shell. A pull rod is fixed to the outer wall of the hinge shaft, and a support block is fixed to one end of the pull rod. A support rod is fixedly connected through the support block. A square block is symmetrically fixed to the bottom of the inner wall of the outer shell, and one end of a third spring is connected to one side of the square block. The other end of the third spring is connected to a guide plate, and the bottom of the guide plate is slidably connected to the outer shell. One end of the support rod contacts one side of the guide plate, and a threaded tube is threadedly connected to the guide plate through a connecting block.

[0011] More preferably, it also includes square through slots. Square through slots are formed on the outer walls of both heating chambers. A third connecting rod is slidably connected within the square through slots. One end of the threaded tube can abut against the third connecting rod when it moves. A support plate is fixed to one end of the third connecting rod. One side of the support plate is slidably connected to the heating chamber. A winding wheel is fixed to the outer side of the support plate. The winding wheels are staggered. A fourth connecting rod is fixed to one side of each of the two heating chambers. A cooling chamber is fixed to one end of each of the two fourth connecting rods. One side of the cooling chamber is slidably connected to the outer shell. A fan is installed on one side of the inner wall of each of the two cooling chambers. A condenser pipe is installed at the bottom of the inner wall of each of the two cooling chambers.

One end of each condenser pipe passes through the outer shell and the bottom of the base plate, respectively, and connects to the cooling box. Guide rollers are rotatably connected to opposite sides of the two cooling chambers.

[0012] Compared with the prior art, this utility model has the following advantages: Through the cooperation of the handle and the Π-shaped connecting plate, as the Π-shaped connecting plate moves downwards, it drives the wedge block downwards, causing the round-headed rod to disengage from the wedge block's restraint. Subsequently, the wedge block drives the pressure plate to move, causing the concave and convex circular plates to come into contact and clamp and restrain the yarn roller, preventing the yarn roller from swaying due to the influence of the take-up roller. This allows the polyester yarn to be caught inside the device and broken. Simultaneously, through the cooperation of the second connecting rod, the square plate, and the threaded tube… As the second connecting rod moves downward, it drives the sliding groove inside the square plate to press against the sliding shaft on the heating chamber, causing the heating chambers to move closer together. The heating chambers then drive the first connecting plate to move, causing the first connecting plate to move the pull rod and disengage the guide plate from its limit position. The movement of the guide plate then drives the threaded tube to move the winding wheel on the support plate, causing the winding wheel to stretch the polyester filament. This prevents the polyester filament from breaking due to the different types of polyester filaments having varying internal tensions during the winding process, which could lead to the polyester filaments with lower tension breaking.

One end of the support rod 30 is in contact with one side of the guide plate 31. When the guide plate 31 moves, it can squeeze the support rod 30 to slide. A threaded tube 32 is threadedly connected to the guide plate 31 through a connecting block.

[0030] It also includes a square through groove 34. The outer walls of both heating chambers 24 are provided with square through grooves 34. A third connecting rod 35 is slidably connected in the square through groove 34. When the threaded tube 32 moves, it can abut against the third connecting rod 35. A support plate 36 is fixed to one end of the third connecting rod 35. One side of the support plate 36 is slidably connected to the heating chamber 24.

A cooling chamber 39 is fixed to one end of each of the two fourth connecting rods 38. One side of the cooling chamber 39 is slidably connected to the outer shell 2. A fan 40 is installed on one side of the inner wall of each of the two cooling chambers 39. A condenser pipe 41 is installed at the bottom of the inner wall of each of the two cooling chambers 39. A cooling box 5 is fixed to the bottom of the bottom plate 6. The cooling box 5 is located directly below the two condenser pipes 41. One end of each of the two condenser pipes 41 passes through the bottom of the outer shell 2 and the bottom plate 6, and is connected to the cooling box 5. Guide rollers are rotatably connected to the opposite sides of the two cooling chambers 39.

[0031] Initially, the untreated polyester yarn on the yarn roller 12 is manually pulled to guide it through the interlaced winding wheel 37 and the gap between the two guide rollers inside the device, and finally wound onto the take-up roller 42. Then, the yarn roller 12 is manually placed on the bracket 10. At this time, the weight of the yarn roller 12 causes the handle 7 under the bracket 10 to move downwards along the circular shaft 8, compressing the first spring 9. The two convex circular plates 11 are then manually pushed, causing them to engage with both ends of the yarn roller 12, thus fixing the yarn roller 12. As the handle 7 moves downwards, it simultaneously moves the Π-shaped connecting plate 13 and the convex circular plates 11 downwards. The Π-shaped connecting plate 13, through the second spring, drives the pressure plate 14, wedge block 15, and concave circular plate 16 to move downwards synchronously. It is worth noting that the second spring is initially under the influence of gravity. In the compressed state, when the handle 7 moves downward, the wedge block 15 contacts and slides with the round-headed rod 19. At this time, relative to the angle of the wedge block 15, the round-headed rod 19 is in an upward moving state through the engagement of the buckle 18 until the round-headed rod 19 disengages from the wedge block 15. Then, the second spring resets, driving the wedge block 15, the pressure plate 14, and the concave circular plate 16 to move closer to the convex circular plate 11 until the concave circular plate 16 and the convex circular plate 11 are in contact, clamping and limiting the yarn roller 12. This ensures that the polyester yarn is subjected to uniform tension during the unfolding process, preventing the yarn roller 12 from swaying due to the influence of the take-up roller 42, thereby hanging the polyester yarn inside the device and breaking it. At the same time, the handle 7 drives the two second connecting rods 20 to move downward. The 0-axis causes the two square plates 21 to move downwards, causing the sliding grooves 22 within the two square plates 21 to press down on the sliding shafts 23 on the two heating chambers 24. The sliding shafts 23, under force, slide along the sliding grooves 22, causing the two heating chambers 24 to move relative to each other until they close. During this relative movement, the two heating chambers 24 respectively cause the two first connecting plates 25 to move relative to each other. The hinge joints between the two first connecting plates 25 and the second connecting plates 26 rotate under force, causing the two second connecting plates 26 to move the hinge shaft 27. The movement of the hinge shaft 27 causes the pull rod 28 and the support block 29 to move synchronously. The support block 29 causes the support rod 30 to slide along the two guide plates 31 until the support rod 30 disengages from the two guide plates 31. At this point, the third spring releases, causing the two guide plates 24 to move simultaneously. The guide plate 31 moves back to its original position. Notably, the third spring is in a compressed state. Simultaneously, the threaded tubes 32 on the two guide plates 31 move and push the two third connecting rods 35 to move. The two third connecting rods 35 respectively drive the winding wheels 37 on the two support plates 36 to move. By having the two winding wheels 37 move closer and closer together, the polyester filaments can be stretched. Then, the steaming chamber 4 is started to heat the polyester filaments in the heating chamber 24. When different types of polyester filaments need to be heated and shaped, the operator can adjust the moving distance of the threaded tube 32 by rotating it according to the different tensions of the polyester filaments. This increases or decreases the distance that the threaded tube 32 pushes the third connecting rods 35 to move, thereby allowing the winding wheels 37 on the support plates 36 to stretch the polyester filaments to different degrees.To avoid uneven internal tension in different types of polyester yarn during the winding process, which could cause the lower tension yarn to break, the two heating chambers 24 move, causing the two fourth connecting rods 38 to move. These fourth connecting rods 38 then close the two cooling chambers 39, bringing the two guide rollers closer together to clamp and guide the polyester yarn. Subsequently, the condenser pipe 41 and fan 40 on the cooling chamber 5 are activated, rapidly reducing the polyester yarn temperature through forced air cooling and condensate circulation. This achieves a low-shrinkage, high-elasticity shaping effect for the polyester yarn within the cooling chamber 39. The drive motor 3 is manually activated, and its output drives the take-up roller 42 to rotate. The shaped polyester filaments are wound up (at this time, the weight of the filament roller 12 keeps the first spring 9 in a compressed state). After winding is complete, the drive motor 3, steaming box 4, and cooling box 5 are manually stopped. The filament roller 12 is released from its fixation by the two convex circular plates 11 and removed. At this time, under the action of the elastic force of the first spring 9, the handle 7 moves upward, and at the same time, the Π-shaped connecting plate 13 and the convex circular plate 11 move upward. The Π-shaped connecting plate 13 drives the second spring, pressure plate 14, wedge block 15, and concave circular plate 16 to move upward. Relative to the angle of the wedge block 15, the round-head rod 19 is in a downward moving state through the engagement of the buckle 18, so that the round-head rod 19 and the wedge block 15 move downward. Upon contact of the shaped block 15, the second spring is compressed, causing the pressure plate 14 and the concave circular plate 16 to move back to their original positions, separating the concave circular plate 16 from the convex circular plate 11. Simultaneously, the handle 7 moves the two second connecting rods 20 upwards, which in turn move the two square plates 21 upwards, causing the sliding grooves 22 within the two square plates 21 to move upwards. The sliding grooves 22 within the two square plates 21 press upwards against the sliding shafts 23 on the two heating chambers 24. The sliding shafts 23, under pressure, move the heating chambers 24 until they separate. During the relative movement of the two heating chambers 24 under pressure, the two first connecting plates 25 are moved respectively. The movement of component 25 causes the two second connecting plates 26 to rotate under force, which in turn causes the hinge shaft 27 to move and reset. The hinge shaft 27 then moves the pull rod 28 and the support block 29. The support block 29 moves the support rod 30 to press against the two guide plates 31 and slide along them, thus limiting their movement. The third spring is compressed, and simultaneously, the two third connecting rods 35 are manually pushed. These rods move the winding wheels 37 on the two support plates 36 to reset. Simultaneously, the movement of the two heating chambers 24 moves the two fourth connecting rods 38, which in turn move the two cooling chambers 39 to separate and reset. The device is now fully reset.
