Description

Technical Field

[0001] The utility model relates to the technical field of yarn winding, in particular to a fixed-length wire-breaking device for winding polyester yarns. Background Art

[0002] Polyester yarn refers to yarn spun from polyester as raw material. Polyester is a type of polymer fiber made by spinning, mostly referring to fibers produced from ethylene phthalate as raw material. The so-called "yarn" is actually a general term for "yarn" and "thread". In clothing materials science, it is defined as follows: "yarn" is a slender object with certain strength and linear density formed by arranging many short fibers or filaments in an approximately parallel state and twisting them axially; and "thread" is a strand formed by twisting two or more single yarns. Polyester yarn is a cloth-making material, usually used in clothing production. In order to facilitate transportation and storage during the production of polyester yarn, the polyester yarn needs to be rolled into a tube, and the polyester yarn needs to be cut at a fixed length during winding.

[0003] According to the "A fixed-length wire-breaking device for polyester yarn winding (publication number: CN217920851U; application number: 202221679406.3)" published on the patent website, the above application optimizes the problem that "the existing fixed-length wire-breaking device for polyester yarn winding has poor structural rationality, resulting in a low degree of coordination with the winding drum; the existing fixed-length wire-breaking device for polyester yarn winding has a low degree of automation, resulting in poor fixed-length wire-breaking effect". However, when the wire-breaking device in the above application is in use, it is impossible to fix the stress-bearing part of the polyester yarn, so that the polyester yarn will be squeezed by the tool during the cutting process and the position will be shifted. The tool needs to be pressed down multiple times to complete the cutting of the polyester yarn, affecting the working efficiency of the wire-breaking device. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The utility model provides a technical solution:

[0026] Embodiment 1

[0027] Combination Figure 1 and Figure 2 A fixed-length thread-breaking device for winding polyester yarn comprises a base 3, a winding mechanism 1 is arranged on the right side of the top of the base 3, and a tensioning mechanism 2 is arranged on the left side of the top of the base 3.

[0028] The winding mechanism 1 includes a support assembly 11 , a drive assembly 12 and a transmission assembly 13 . The support assembly 11 is arranged on the top right side of the base 3 , the drive assembly 12 is arranged on the top of the base 3 below the support assembly 11 , and the transmission assembly 13 is arranged on the rear side of the drive assembly 12 .

[0030] Furthermore: the staff only needs to start the dual-axis motor 1201 to drive the outer ring of the upper winding roller 1103 to complete the winding of the polyester yarn. The operation is simple and convenient for the staff to use. The outer ring diameter of the transmission wheel 1303 is larger than the outer ring diameter of the driving wheel 1301, so that the rotation speed of the transmission wheel 1303 is lower than the rotation speed of the driving wheel 1301, so that the rotation rate of the winding roller 1103 is more stable, and the polyester yarn will not be misplaced during the winding process due to the winding roller 1103 rotating too fast.

[0031] Embodiment 2

[0032] See also Figures 1 to 4 On the basis of Example 1, it is further obtained that the tensioning mechanism 2 includes a line transmission component 21, a connecting component 22 and a speed difference component 23, the line transmission component 21 is arranged on the left side of the top of the base 3, the connecting component 22 is arranged on the front side of the line transmission component 21, and the speed difference component 23 is arranged on the rear side of the line transmission component 21.

[0033] The wire transmission component 21 includes a fixed frame 2101, which is fixedly connected to the left side of the top of the base 3, and a sleeve frame 2102 is fixedly connected to the top of the fixed frame 2101. The sleeve frame 2102 is rotatably connected to wire transmission rollers 2103 on both sides. The inner ring of the wire transmission roller 2103 is fixedly connected to a second rotating shaft 2104, and the second rotating shaft 2104 is rotatably connected to the outer side of the sleeve frame 2102. The front side of the second rotating shaft 2104 is fixedly connected to a meshing gear 2105, and the meshing gears 2105 on the upper and lower sides are meshed with each other.

[0034] Furthermore: the wire delivery rollers 2103 on the left and right sides rotate by following the start-up of the dual-axis motor 1201 through the transmission of the wire delivery assembly 21, and during the rotation of the left wire delivery roller 2103, since the outer ring diameter of the large roller 2303 is slightly larger than the outer ring diameter of the small roller 2301, the rotation rate of the left wire delivery roller 2103 is smaller than the rotation rate of the right wire delivery roller 2103, so that the polyester yarn located between the left and right wire delivery rollers 2103 can be kept taut during the transmission process, so that the yarn will not be misplaced or offset when the cutting structure cuts the polyester yarn, which makes it easier for the cutting structure to cut the polyester yarn.

[0035] In actual operation, when the device is used, when the polyester yarn needs to be wound, the staff first fixes one end of the yarn to the outer ring of the winding roller 1103, and then only needs to start the double-axis motor 1201. The double-axis motor 1201 starts to drive the driving wheel 1301 to rotate through the rotating shaft 1202, and the driving wheel 1301 rotates through the transmission belt 1302 to drive the transmission wheel 1303 to rotate, and the transmission wheel 1303 rotates through the transmission belt 1302 to drive the transmission wheel 1303 to rotate, and the transmission wheel 1303 rotates to wind the polyester yarn fixed on the outside;

[0036] When the winding roller 1103 is winding the yarn, the driving wheel 2201 rotates along with the rotation shaft 1202, the driving wheel 2201 rotates through the transmission belt 2202 to drive the driving wheel 2203 to rotate, the driving wheel 2203 rotates through the support shaft 2204 to drive the wire feeding roller 2103 at the lower right side to rotate, the wire feeding roller 2103 at the lower right side rotates through the rotating shaft 2104 to drive the small roller 2301 to rotate, the small roller 2301 rotates through the transmission belt 3 2302 to drive the large roller 2303 to rotate in the same direction, the large roller 2303 rotates through the rotating shaft 2104 to drive the wire feeding roller 2103 at the lower left side to rotate, and the wire feeding rollers 2103 at the lower left and right sides rotate and rotate in the opposite direction through the meshing gears 2105 meshing with each other on the upper and lower sides, so that the wire feeding rollers 2103 at the upper and lower sides transmit the middle yarn to the right in the opposite direction;

[0037] When the polyester yarn wound on the outer ring of the winding roller 1103 reaches the standard and needs to be processed for broken wire, the staff first fixes the cutting structure at the top of the base 3 between the left and right wire feeding rollers 2103, so that the cutting structure can cut the wire segment between the left and right wire feeding rollers 2103 when working, and then starts the cutting device to complete the winding and broken wire processing of the polyester yarn.
