Description

Technical Field

[0001] This invention relates to the field of polyester processing technology, and in particular to an automatic deviation correction and dropping device for polyester yarn cakes. Background Technology

[0002] As the core raw material in the polyester texturing process, the quality of pre-oriented polyester yarn (POY) directly determines the success rate of texturing at the end. The main factors affecting POY yarn breakage during texturing (breakage refers to the breakage that occurs when unwinding the POY yarn after the end of the yarn on the yarn tray has been handed over to the spare yarn end) include paper tube damage, incomplete removal of POY surface yarn, uneven quality of the POY bottom layer yarn, and abnormal texturing splicing quality.

[0003] One cause of paper tube breakage is the imperfection of the automatic unwinding machine. Taking the winding head produced by Zhengzhou Textile Machinery Co., Ltd. as an example, the pusher plate of this winding head is semi-grooved. When the polyester yarn cake is fully wound and waiting for the automatic unwinding machine to unwind it, the empty chuck is winding the yarn, and the polyester yarn cake is gradually increasing in size. Therefore, both chuck shafts will move. The center point of the fully wound chuck shaft will gradually deviate from the center position of the pusher plate groove, which will further reduce the contact area between the pusher plate and the paper tube of the yarn cake on the chuck shaft. During the unwinding process, because the contact area between the paper tube and the pusher plate is small, the force-bearing area is small, which makes the opening of the paper tube easy to be pushed and damaged. The existing solution is to manually unwind the paper tube when the deviation occurs, which is inefficient and needs to be improved. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide an automatic polyester yarn cake correction and dropping device, which realizes the automatic dropping action of the paper tube on the chuck shaft and improves the adaptability to the problem of chuck shaft misalignment.

[0005] To solve the above-mentioned technical problems, the present invention provides an automatic polyester yarn cake correction and feeding device, comprising: a pusher plate, an industrial control computer, a distance sensor and its driving mechanism. The pusher plate is movably disposed on one side of the chuck shaft along the axial direction of the chuck shaft and located behind the paper tube on the chuck shaft. A U-shaped groove passing through the chuck shaft is provided at the end of the pusher plate facing the chuck shaft. A through hole is provided on the pusher plate directly above or below the chuck shaft. The distance sensor is disposed in the through hole and points towards the chuck shaft. The driving mechanism includes a first motor, a guide rail, a first mounting plate, a second mounting plate and a third mounting plate. The pusher plate contains... A circular hole is located on one side of the chuck shaft, and a fixed plate is disposed in the circular hole. A guide rail is disposed parallel to one side of the chuck shaft and passes through the fixed plate. A first mounting plate and a second mounting plate are disposed at both ends of the guide rail. A third mounting plate is disposed parallel to the outside of the guide rail and is located between the first mounting plate and the second mounting plate. A retaining ring is disposed on the push cylinder plate, located on the front and back of the fixed plate. One of the retaining rings has a toothed groove on its inner wall. A first motor is disposed on the fixed plate, and the output end of the first motor is provided with a gear that meshes with the toothed groove. A ranging sensor is connected to an industrial control computer to send signals. The industrial control computer is connected to the first motor to control its rotation.

[0006] In a preferred embodiment of the present invention, the fixed disk is provided with a linear bearing corresponding to the guide rail.

[0007] In a preferred embodiment of the present invention, two synchronous pulleys are arranged at a distance from front to back on the third mounting plate, and a synchronous belt is arranged between the two synchronous pulleys. A cantilever extending into the synchronous belt is provided on the fixed plate.

[0008] In a preferred embodiment of the present invention, a clamping plate corresponding to the cantilever is provided above the synchronous belt, and a first screw connected to the cantilever is provided on the clamping plate.

[0009] In a preferred embodiment of the present invention, the third mounting plate is provided with a second motor that drives one of the synchronous pulleys to rotate.

[0010] In a preferred embodiment of the present invention, the industrial control computer is connected to the second motor for rotation control.

[0011] In a preferred embodiment of the present invention, the guide rail comprises at least two cylinders.

[0012] In a preferred embodiment of the present invention, the retaining ring is provided with a second screw that connects to the push cylinder plate. In a preferred embodiment of the present invention, the retaining ring is concentric with the fixing plate, and the diameter of the fixing plate is larger than the inner diameter of the retaining ring.

[0013] In a preferred embodiment of the present invention, the width of the U-shaped groove is greater than the diameter of the chuck shaft.

[0014] The beneficial effects of this invention are as follows: The automatic correction and dropping device for polyester yarn cakes disclosed in this invention uses a distance sensor to detect the offset of the chuck shaft. When the chuck shaft deviates downward from the center position of the U-shaped groove, the pusher plate is driven to flip downward to maintain the chuck shaft in the center position of the U-shaped groove. This ensures the contact area between the pusher plate and the paper tube when dropping the paper tube, thereby reducing the paper tube breakage problem and helping to reduce the problem of over-tail breakage caused by paper tube breakage during the texturing process of POY raw yarn.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort, wherein: Figure 1 This is a schematic diagram of a preferred embodiment of the automatic correction and dropping device for polyester yarn cakes according to the present invention; Figure 2 yes Figure 1 A sectional view along the AA direction. Detailed Implementation

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-2 The embodiments of the present invention include: like Figure 1 The automatic polyester yarn cake correction and dropping device shown is used for the stable dropping of paper tube 2 onto the chuck shaft 1 of the winding head. It includes: a pusher plate 6, an industrial control computer, a distance sensor 8, and its drive mechanism. The pusher plate 6 is movably disposed on one side of the chuck shaft 1, located behind the paper tube 2 on the chuck shaft 1. One end of the pusher plate 6 facing the chuck shaft has a U-shaped groove 13 that passes through the chuck shaft 1, facilitating contact between the pusher plate 6 and the tail of the paper tube 2, pushing the paper tube 2 forward to achieve automatic dropping. The width of the U-shaped groove 13 is greater than the diameter of the chuck shaft 1, with a gap of approximately 2mm on each side to avoid contact and friction between the chuck shaft 1 and the inner wall of the U-shaped groove 13.

[0018] A through hole 12 is provided on the pusher plate 6, located directly above or below the chuck shaft 1. The distance sensor 8 is installed in the through hole 12 and points towards the chuck shaft 1. The distance sensor 8 is used to detect the offset of the chuck shaft 1 in the U-shaped groove 13.

[0019] like Figure 2 As shown, the driving mechanism includes a first motor 20, a guide rail 3, a first mounting plate 11, a second mounting plate 5, and a third mounting plate 4. The pusher plate 6 has a circular hole located on one side of the chuck shaft 1. A fixing plate 14 is provided in the circular hole, and a bearing can be installed in the circular hole to provide rotational support for the pusher plate 6.

[0020] The guide rail 3 is arranged parallel to one side of the chuck shaft 1 and passes through the fixed disk 14. In this embodiment, the fixed disk 14 is provided with a linear bearing 15 corresponding to the guide rail 3, which facilitates the linear movement of the fixed disk 14 along the guide rail 3. The guide rail 3 uses at least two cylinders to avoid the torsion of the fixed disk 14 and ensures high stability.

[0021] like Figure 1 As shown, the first mounting plate 11 and the second mounting plate 5 are positioned at both ends of the guide rail 3. The ends of the guide rail 3 are connected to the first mounting plate 11 and the second mounting plate 5 respectively using bolts, facilitating assembly. The third mounting plate 4 is arranged parallel to the outside of the guide rail 3 and is located between the first mounting plate 11 and the second mounting plate 5. After the first mounting plate 11, the second mounting plate 5, and the third mounting plate 4 are fixed with bolts, they form a fixed C-shaped structure that can be installed on the frame of the winding head, providing structural stability.

[0022] like Figure 2 As shown, retaining rings 22 are provided on the pusher plate 6, located on the front and back of the fixed plate 14. The retaining rings 22 are equipped with second screws 21 that connect to the pusher plate 6, facilitating assembly. The retaining rings 22 are concentric with the fixed plate 14, and the diameter of the fixed plate 14 is larger than the inner diameter of the retaining rings 22. The retaining rings 22 limit the fixed plate 14 within the pusher plate 6, preventing it from detaching.

[0023] One of the retaining rings 22 has a toothed groove on its inner wall. The first motor 20 is mounted on the fixed plate 14, and the output end of the first motor 20 is provided with a gear 7 that meshes with the toothed groove. The first motor 20 can be fixed to the fixed plate 14 with bolts, making the structure robust. The angle of the pusher plate 6 is adjusted by using the first motor 20 to drive the rotation of the gear 7.

[0024] The ranging sensor 8 is connected to the industrial control computer to send signals. The industrial control computer is connected to the first motor 20 to control the rotation. When the chuck shaft 1 deviates downward from the center position of the U-shaped groove 13, the pusher plate 6 is driven to flip downward, changing the center position of the U-shaped groove 13 and maintaining the chuck shaft 1 in the center position of the U-shaped groove 13. This ensures that the contact area between the pusher plate 6 and the tail end of the paper tube 2 is large when the paper tube 2 is dropped, and the paper tube 2 is subjected to more uniform force, thereby reducing the problem of paper tube 2 breakage.

[0025] like Figure 1 As shown, two synchronous pulleys 10 are arranged at intervals on the third mounting plate 4, and a synchronous belt 9 is arranged between the two synchronous pulleys 10. In this embodiment, a second motor 19 is arranged on the third mounting plate 4 to drive one of the synchronous pulleys 10 to rotate. The industrial control computer is connected to the second motor 19 to control the rotation and realize automatic drum dropping.

[0026] like Figure 2 As shown, the fixed plate 14 is provided with a cantilever 16 extending into the synchronous belt 9. Above the synchronous belt 9, there is a clamping plate 17 corresponding to the cantilever 16. The clamping plate 17 is provided with a first screw 18 connected to the cantilever 16 to clamp the synchronous belt 9, so that the fixed plate 14 can move back and forth with the synchronous belt 9 to provide the power for the cylinder to fall into the cylinder.

[0027] In summary, the automatic correction and dosing device for polyester yarn cakes disclosed in this invention can automatically detect the offset of the chuck shaft and correct the offset by using the angle change of the push plate, ensuring the contact area between the push plate and the paper tube during the dosing process and strengthening the protection of the paper tube.

[0028] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
