Description

Technical Field

[0001] The utility model relates to the field of textile equipment, in particular to a raw silk frame for a texturing machine. Background Art

[0002] In the post-processing of polyester filament, the raw silk frame of the texturing machine plays a role in placing the raw silk in the post-processing; the utility model patent with the application number: CN201920416408.5 discloses a raw silk frame for a texturing machine, which sets a red line emitter and a receiver for each raw silk, and the raw silk is placed between the emitter and the receiver. When the raw silk is broken, the infrared receiver receives the infrared ray of the infrared emitter, so that the alarm gives an alarm; this kind of broken wire monitoring method requires a lot of groups of infrared emitters and receivers, with a redundant structure and high cost; moreover, the raw silk will vibrate during the movement process, and the raw silk is very thin, so the monitoring area available for the emitter and the receiver is very small, and the vibration of the raw silk is extremely easy to deviate from the monitoring area, causing the alarm to give a false alarm. Summary of the Invention

[0003] The utility model provides a raw silk frame for a texturing machine, aiming to solve the problems of complex broken wire monitoring device, high cost and easy false alarm of the raw silk frame.

[0004] The technical solution it adopts includes a base and a vertical column installed on the base. A wire hanging unit is installed on the column. The wire hanging unit includes a horizontal mounting plate coaxially fixed on the column. A plurality of vertical wire hanging rods are circumferentially and evenly distributed on the mounting plate. A broken wire monitoring unit is arranged on the column above the wire hanging unit. The broken wire monitoring unit includes a disc. The center of the disc is installed on the column through a spherical hinge, so that the disc can rotate in all directions around the center of the spherical hinge. A plurality of radial first wire grooves are circumferentially and evenly distributed on the side wall of the disc. The number of the first wire grooves is the same as the number of the wire hanging rods of each group of wire hanging units. A wire collecting ring is installed at the upper end of the column; the broken wire monitoring unit further includes two distance sensors and an alarm. The distance sensors are vertically installed on the column or the mounting plate below the disc, and the projections of the distance sensors on the disc are not on the same diameter of the disc.

[0005] A horizontal wire collecting disc is installed on the column above the mounting plate and below the disc. Second wire grooves are circumferentially and evenly distributed on the wire collecting disc. The number of the second wire grooves is the same as the number of the wire hanging rods of each group of wire hanging units. After the raw silk is drawn out from the raw silk bobbin, it passes through the second wire grooves one by one and then through the first wire grooves.

[0006] The second wire grooves are in a V shape, one end of the second wire grooves is closed and the other end is open to the side wall of the wire collecting disc.

[0007] The wire hanging unit includes multiple groups distributed up and down.

[0008] The disk surface of the installation disk is hollowed out, and the raw filaments in the lower layer can pass through the upper installation disk through the hollowed-out part.

[0009] In the utility model, multiple raw filaments are evenly distributed outside the disk, and the forces exerted on the disk by the tensions of the raw filaments are balanced to monitor wire breakage. All the raw filaments can be monitored simultaneously, and it is not necessary to set up a set of wire breakage monitoring devices for each raw filament, which simplifies the monitoring structure and equipment cost. Moreover, false alarms will not be caused by the jitter of the raw filaments. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Combined with the attached drawings, the utility model includes a base 1 and a vertical column 2 installed on the base 1. A wire hanging unit is installed on the column 2. The wire hanging unit includes a horizontal installation disk 3. The installation disk 3 is coaxially fixed on the column 2. A number of vertical wire hanging rods 4 are evenly distributed in a circle on the installation disk 3. A wire breakage monitoring unit is arranged on the column 2 above the wire hanging unit. The wire breakage monitoring unit includes a disk 5. The center of the disk 5 is installed on the column 2 through a spherical hinge 6, so that the disk 5 can rotate in all directions around the center of the spherical hinge 6. A plurality of radial first wire grooves 7 are evenly distributed in a circle on the side wall of the disk 5. The number of the first wire grooves 7 is the same as the number of the wire hanging rods 4 of each group of wire hanging units. A wire collecting ring 8 is installed at the upper end of the column 2. The raw wire spools are put on the wire hanging rods 4, and the wire ends are pulled out and respectively clamped in the first wire grooves 7 one by one. All the wire ends then pass through the wire collecting ring 8 together. Since the raw filaments are evenly distributed in a circle on the disk 5, the forces exerted on the disk 5 by the tensions of the raw filaments are balanced, and the disk 5 is in a horizontal state. If one or more raw filaments are broken, the forces exerted on the disk 5 by the remaining raw filaments are no longer balanced, and the disk 5 will surely deflect to one side. The wire breakage monitoring unit further includes two distance sensors 9 and an alarm 10. The distance sensors 9 are vertically installed on the column 2 or the installation disk 3 below the disk 5. The projections of the distance sensors 9 on the disk 5 are not on the same diameter of the disk 5. When a raw filament is broken, the disk 5 deflects, and the monitoring values of at least one distance sensor 9 change, and the alarm 10 gives an alarm.

[0016] A horizontal wire collecting disc 11 is installed on the upright post 2 above the mounting disc 3 and below the disc 5. Second wire grooves 12 are evenly distributed in a circle on the wire collecting disc 11. The number of the second wire grooves 12 is the same as the number of the wire hanging rods 4 of each group of wire hanging units. After the raw wires are drawn out from the raw wire reels, they pass through the second wire grooves 12 one by one in correspondence, and then pass through the first wire grooves 7. The second wire grooves 12 have the function of gathering and evenly distributing the raw wires, making the circumferential distribution of the raw wires uniform, and reducing the influence of the vibration of the raw wires caused by the rotation of the raw wire reels on the disc 5.

[0017] The second wire grooves 12 are V-shaped. One end of the second wire groove 12 is closed and the other end opens to the side wall of the wire collecting disc 11. This shape is convenient for threading the wires. The raw wires can be clamped into the second wire grooves 12 from the open ends of the second wire grooves 12 and moved to the closed ends of the second wire grooves 12.

[0018] The wire hanging units include multiple groups distributed up and down, and multiple groups of raw wires can be threaded through for standby.

[0019] The surface of the mounting disc 3 is in a hollow shape, and the raw wires in the lower layer can pass through the mounting disc 3 in the upper layer through the hollow parts.

[0020] When the utility model is in use, the raw wire reels are put on the wire hanging rods 4, and the wire hanging units are standby in turn from top to bottom. After the raw wires are drawn out from the raw wire reels, they pass through the second wire grooves 12 one by one in correspondence, then pass through the first wire grooves 7, and then are concentratedly passed through the wire collecting ring 8 and sent into the texturing machine in the form of a wire bundle.

[0021] When all the raw wires are not broken, since the raw wires are evenly distributed in a circle on the disc 5, the acting forces of the raw wires on the disc 5 are balanced, and the disc 5 is in a horizontal state. At this time, the monitoring values of the two distance sensors 9 remain unchanged. If one or more raw wires are broken, the acting forces of the remaining raw wires on the disc 5 are no longer balanced, and the disc 5 will surely deflect to one side. Then, the monitoring value of at least one distance sensor 9 will become larger or smaller, and the alarm 10 will give an alarm.

[0022] In order to adapt to the disturbance of the disc 5 during the feeding of the raw wires, an allowable fluctuation range can be set for the monitoring values of the distance sensors 9. When the monitoring values fluctuate within this range, the alarm 10 does not give an alarm. Only when the range is exceeded, the alarm 10 will give an alarm for wire breakage.

[0023] The utility model monitors wire breakage by evenly distributing multiple raw wires outside the disc 5 and balancing the acting forces of the tensions of the raw wires on the disc 5. It can monitor all the raw wires at the same time, and it is not necessary to set a set of wire breakage monitoring devices for each raw wire, which simplifies the monitoring structure and equipment cost; moreover, it will not cause false alarms due to the jitter of the raw wires.
