Description

Technical Field

[0001] The invention relates to a texturing machine, and more particularly to a yarn package edge stroke correction mechanism. Background Art

[0002] The texturing machine, also known as the stretch yarn machine and the false twist texturing machine, is a textile equipment that stretches, false twists and deforms the yarn. During the winding process, the edge of the yarn package will form a slope. The formation and correction of this slope is achieved through the motion correction mechanism. The motion correction mechanism can ensure that the position of the yarn changes within the motion correction length (maximum 20mm) of the two edges of the package, thereby avoiding the formation of a harder package at the edge. The motion correction mechanism is usually composed of a driving mechanism and a correction component. The driving mechanism on one side of the correction component drives the correction component to move back and forth, thereby realizing the motion correction of the yarn package. The current correction component is free at the end away from the driving mechanism, and the gap between the correction components is large during the assembly process, which makes the motion correction mechanism have a large free moving distance (moving gap), thereby affecting the yarn winding effect. Therefore, it is urgently needed to improve this. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 7 As shown, the present embodiment discloses a yarn package edge stroke correction mechanism, comprising a groove drum box assembly 1 and a correction assembly, wherein the correction assembly is installed in the groove drum box assembly 1, and the groove drum box assembly 1 is a prior art, and the two ends of the correction assembly are respectively connected with a second tension spring 100 and a driving mechanism 3, and the driving mechanism 3 can drive the correction assembly to move back and forth so that the second tension spring 100 can reciprocate and extend, and one end of the correction assembly is connected to the driving mechanism 3, and the other end is connected to the fuselage 200 through the second tension spring 100. The second tension spring 100 forms a restraining force on the correction assembly, eliminates the free end of the correction assembly, thereby improving the stability of the correction assembly during operation, and through the second tension spring 100, a pulling force can be always applied to the correction assembly, and when the correction assembly has an assembly gap, the free movement of the correction assembly can be limited, thereby improving the yarn winding effect.

[0027] The correction assembly includes a plurality of connecting rods 2, and the plurality of connecting rods 2 are distributed in a straight line. Two adjacent connecting rods 2 are connected by a connecting block 4. The connecting rod 2 near the driving mechanism 3 is connected to the driving mechanism 3, and the connecting rod 2 near the second tension spring 100 is connected to the second tension spring 100. Limiting columns 21 are provided at both ends of the connecting rod 2, and a through hole 22 is provided in the limiting column 21. One end of the second tension spring 100 is connected to the through hole 22 at the connecting rod 2 near the second tension spring 100 and the other end is connected to the fuselage 200. Two adjacent connecting rods 2 are connected by two connecting blocks 4, and the connecting blocks 4 respectively abut against the two sides of the adjacent limiting columns 21 of the two connecting rods 2. The two ends of the connecting block 4 abut against the end of the connecting rod 2 to limit the position, and the two connecting blocks 4 are fixed to the connecting rod 2 by bolts.

[0028] By setting the connecting block 4, the connection between two adjacent connecting rods 2 can be achieved with good connection reliability, and through the cooperation between the first connecting block 4 and the limiting column 21, the assembly error between the two connecting rods 2 can be reduced during installation, the assembly gap can be reduced, and the connection accuracy between the two connecting rods 2 can be improved.

[0029] A fixed block 6 is fixed to the lower part of the connecting rod 2 near the driving mechanism 3, and two movable blocks 7 are provided inside the drum box assembly 1, and the fixed block 6 is located between the two movable blocks 7. The connecting rod 2 moves so that the fixed block 6 can abut against or disengage from the movable block 7. There are two fixed blocks 6, and the two fixed blocks 6 correspond to the two movable blocks 7 one by one. A first protrusion 61 is provided on the side of the fixed block 6, and the movable block 7 includes a second protrusion 71. The first protrusion 61 can abut against or stay away from the second protrusion 71. The distance between the fixed block 6 and the movable block 7 on the same side is the movable distance of the connecting rod 2. When the connecting rod 2 moves back and forth, the corresponding fixed block 6 can hit the left and right movable blocks 7 respectively, thereby limiting the movable distance of the connecting rod 2, eliminating the movable virtual position of the connecting rod 2, and further improving the yarn winding effect.

[0030] like Figure 5 As shown, the two movable blocks 7 can move closer to or farther away from each other, and a transmission mechanism 8 is provided in the groove drum box assembly 1, and the transmission mechanism 8 includes a screw rod 81 and a guide rod 82. The movable block 7 is threadedly connected to the screw rod 81, and the movable block 7 is sleeved on the outside of the guide rod 82 to realize the screw rod transmission connection. Rotating the screw rod 81 can drive the movable blocks 7 to move closer to or farther away from each other. The screw rod 81 includes a first thread segment 811 and a second thread segment 812. The two movable blocks 7 are threadedly connected to the first thread segment 811 and the second thread segment 812, respectively. Through the above design, the distance between the two movable blocks 7 can be adjusted, thereby adjusting the distance between the movable block 7 and the fixed block 6, thereby meeting the requirements for different yarn package thicknesses.

[0031] A plurality of threaded holes 23 are provided at the lower portion of the connecting rod 2 near the driving mechanism 3, and the fixed block 6 is fixed to the threaded holes 23 by screws. By fixing the fixed block 6 in different threaded holes 23, the initial position between the fixed block 6 and the movable block 7 can be adjusted, thereby adjusting the moving distance of the connecting rod 2 to meet the requirements of different yarn package thicknesses.

[0032] like Figure 1 and Figure 7 As shown, a plurality of guide wheels 300 are provided in the groove drum box assembly 1, and the guide wheels 300 are located on the upper and lower surfaces of the connecting rod 2. By providing the guide wheels 300, not only can the connecting rod 2 be supported, but also the stability of the movement of the connecting rod 2 can be improved.

[0033] like Figure 3 and Figure 5 As shown, the driving mechanism 3 includes a movable shaft 31, and the movable shaft 31 is connected to the connecting rod 2 through a connecting mechanism 5. The connecting mechanism 5 includes connecting units located on both sides of the movable shaft 31, and the connecting units include a first connecting portion 51 and a second connecting portion 52. The two first connecting portions 51 are fixedly connected to the connecting rod 2 by bolts, and the two second connecting portions 52 are movably connected to the movable shaft 31 through a connecting member 55. The movable shaft 31 can move back and forth to make the movable shaft 31 approach or move away from the connecting rod 2. The movable shaft 31 can drive the connecting rod 2 to move back and forth. A first guide hole 32 is provided inside the movable shaft 31, and the connecting member 55 passes through the first guide hole 32 and both ends of the connecting member 55 are connected to the two first connecting portions 51. Fixed connection, a second guide hole 53 is provided on the side of the second connecting part 52, first convex ribs 34 are provided on both sides of the movable shaft 31, and the two first convex ribs 34 respectively penetrate the second guide holes 53, and a second convex rib 54 corresponding to the first convex rib 34 is provided on the side of the first connecting part 51, and the first convex rib 34 and the second convex rib 54 located on the same side are connected by a first tension spring 56, and a guide groove 33 is provided inside the movable shaft 31, and a return spring 57 is provided in the guide groove 33, and the limit column 21 is inserted into the guide groove 33, and the end of the limit column 21 abuts against one end of the return spring 57, and the driving mechanism 3 is a cylinder or a worm gear transmission mechanism, and the elastic force of the first tension spring 56 and the return spring 57 are both greater than the elastic force of the second tension spring 100.

[0034] In order to ensure that the connecting rod 2 has no movable empty position, the moving distance of the movable shaft 31 is greater than the movable distance of the connecting rod 2. When the movable shaft 31 moves to the right, the first tension spring 56 can pull the connecting rod 2 to move to the right. When the fixed block 6 on the right side abuts the movable block 7 on the right side, the movable shaft 31 continues to move to the right. At this time, the first tension spring 56 is stretched again, and the first convex rib 34 moves to the right along the second guide hole 53, and the left side of the first guide hole 32 is close to the connecting piece 55; when the movable shaft 31 moves to the left, the first tension spring 56 and the second tension spring 100 both rebound, and push the connecting rod 2 to move to the left through the return spring 57. When the fixed block 6 on the left side abuts the movable block 7 on the left side, the movable shaft 31 continues to move to the left. At this time, the return spring 57 and the first convex rib 34 move to the left. Through the above design, not only can the movement of the movable shaft 31 be buffered, but also the connecting rod 2 can respond and move quickly when the movable shaft 31 is working.

[0035] The position of the movable block 7 is adjusted by the driving gear 9. Specifically, one end of the screw rod 81 is connected to the first bevel gear 83. The transmission mechanism 8 includes a rotating shaft 84. The second bevel gear 85 and the third bevel gear 86 are respectively fixed at both ends of the rotating shaft 84. A fourth bevel gear 91 is provided on the front of the driving gear 9. The fourth bevel gear 91 is meshed with the second bevel gear 85, and the third bevel gear 86 is meshed with the first bevel gear 83. Rotating the driving gear 9 can drive the screw rod 81 to rotate, thereby adjusting the distance between two adjacent movable blocks 7, and the distance adjustment is convenient.

[0036] The cam 36 is a hinged seat 35 which is hinged on the hinge seat 35 and is arranged on the upper side of the drive gear 9. The cam 36 is provided with a connecting end 37 on the side of the drive gear 9 away from the drive gear 9. A pull rope 38 is connected to the connecting end 37. The other end of the pull rope 38 is connected to the lower side of the drive gear 31. When the drive shaft 31 moves to the right, the paddle 36 can pass over the drive gear 9. When the drive shaft 31 moves to the left, the end of the paddle 36 can be embedded between two adjacent teeth of the drive gear 9 and push the drive gear 9 to rotate counterclockwise by a tooth. The two movable blocks 7 are driven to move closer through the transmission mechanism 8. The above design can realize that the movable block 7 can be driven to move when the connecting rod 2 moves back and forth. There is no need to control the moving distance of the connecting rod 2 through the computer program of the texturing machine. The operation is convenient and the reliability is good.

[0037] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
