Description

A yarn spinning tensioning device

Technical Field

The utility model relates to a tensioning device, in particular to a yarn-wrapped spinning tensioning device.

Background technique

Wrap spinning is a new spinning method that wraps part of the fiber or another yarn around the yarn core to make a special structure of yarn during the spinning process. For ordinary spinning lines, after the tow comes out of the spinneret, it is bundled and oiled, and then directly goes to the winding device. In order to avoid looseness during spinning and winding, a tensioning device is required to keep the spinning in a tensioned state.

For example, a Chinese patent publication with announcement number CN219470320U discloses a yarn spinning tensioning device, which comprises assembly plates symmetrically arranged on the left and right, and a thread-passing gap for the yarn spinning to pass through is formed between the assembly plates, and a swing-type tensioning thread-passing frame is provided in the thread-passing gap, and the swing-type tensioning thread-passing frame is driven by a rotating drive component arranged on the back of the assembly plate, and a front auxiliary tensioning structure and a rear auxiliary tensioning structure are respectively provided on both sides of the swing-type tensioning thread-passing frame, and the yarn spinning passes through the front auxiliary tensioning structure, the swing-type tensioning thread-passing frame, and the rear auxiliary tensioning structure in sequence.

Some problems were found during the use of the above-mentioned existing yarn spinning tensioning device. First, the device is driven by multiple sets of motors and cylinders, and the overall cost is relatively high. Secondly, when the yarn spinning winding becomes loose, the swinging tensioning wire frame is driven by rotating the driving motor to swing to achieve the tensioning of the spinning, and manual control of the driving motor is required. It takes time for the manual reaction from discovering that the yarn spinning winding becomes loose to starting the driving motor, and the tensioning of the spinning cannot be guaranteed in time.

Compared with the existing device, the spinning can always be kept in a tensioned state without manual adjustment and with a fast response speed.

2. Unscrew the threaded limit pin to release the restriction on the sleeve, then rotate the sleeve to drive the connecting disk to rotate.

Detailed ways

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

Please refer to Figures 1-4. The utility model provides a technical solution: a yarn-wrapped spinning tensioning device, including a tensioning shaft 1 and a spinneret 9. A guide plate 2 is slidably installed on the tensioning shaft 1, and support arms 3 are rotatably installed on both sides of the tensioning shaft 1. A connecting shaft 301 is fixedly installed in the support arm 3 and near the edge of the other end. A fixing seat 4 is arranged below the connecting shaft 301. A first connecting ear 401 is fixedly installed on the fixing seat 4 near one side edge, and the first connecting ear 401 is rotatably connected to the connecting shaft 301. A second connecting ear 402 is fixedly installed on the fixing seat 4 near the edge of the other side. A sleeve pipe 5 is rotatably installed in the first connecting ear 401, and a connecting plate 502 is installed on the sleeve pipe 5. A torsion spring 302 is sleeved on the connecting shaft 301, and one end of the torsion spring 302 is fixedly connected to the connecting plate 502, and the other end of the torsion spring 302 is fixedly connected to the support arm 3.

In this embodiment, the connecting shaft 301 can be rotatably installed above the fixed seat 4 through the cooperation of the sleeve tube 5 and the first connecting ear 401, and the torsion spring 302 can provide a certain torque for the support arm 3. The support arm 3 will drive the tensioning shaft 1 to rotate upward due to the torque, thereby lifting the spinning through the tensioning shaft 1 and putting it in a tensioned state. The tensioned spinning will also press down the tensioning shaft 1. At this time, the tensioning shaft 1 and the spinning will be in a balanced state. When the spinning becomes loose, the torsion spring 302 will drive the tensioning shaft 1 to continue rotating, thereby always keeping the spinning tensioned. Compared with manual adjustment, the reaction speed is fast. At the same time, rotating the sleeve tube 5 can drive the connecting disk 502 to rotate. The connecting disk 502 is fixedly connected to one end of the torsion spring 302, so that the rotation of the threaded through hole 503 can adjust the tightness (torque) of the torsion spring 302, thereby avoiding the problem of excessive pressure applied to the spinning by the tensioning shaft 1, which may cause the spinning to break.

Among them, in order to achieve the purpose of adjusting the distance between the guide plates 2, the present device is implemented by adopting the following technical scheme: a limiting groove 101 is opened on the outer wall of the tensioning shaft 1, a limiting pin block 201 is fixedly installed on the inner wall of the guide plate 2, the limiting pin block 201 cooperates with the limiting groove 101, a bolt connecting foot 202 is fixedly installed on one side of the guide plate 2, and a fixing bolt 203 is installed on the inner thread of the bolt connecting foot 202.

The limiting groove 101 cooperates with the limiting pin block 201 so that the guide disk 2 can only slide on the tensioning shaft 1. The guide disk 2 mainly limits the passing filaments so that the filaments coming out of the spinneret can maintain a suitable spacing to avoid the filaments being entangled together. An anti-skid pad is provided at the end of the fixing bolt 203. Rotating the fixing bolt 203 can drive the anti-skid pad to contact the tensioning shaft 1, so that the guide disk 2 is fixed to the tensioning shaft 1 by friction. The fixing bolt 203 can be loosened according to actual requirements to adjust the spacing between the guide disks 2. At the same time, multiple groups of guide disks 2 are arranged on the tensioning shaft 1, and the excess parts are on both sides of the tensioning shaft 1, as shown in Figure 1, acting as redundancy, which can be directly moved to a suitable position when needed.

Among them, in order to achieve the purpose of limiting the arbitrary rotation of the sleeve 5, the present device adopts the following technical solution: a limiting hole 403 is opened on one side of the second connecting ear 402, and a fixing disk 501 is fixedly installed on the sleeve 5 and on one side of the connecting disk 502. A threaded through hole 503 is opened in the fixing disk 501, and a threaded limiting pin 504 is threadedly installed in the threaded through hole 503, and the threaded limiting pin 504 cooperates with the limiting hole 403.

By rotating the threaded limit pin 504 and cooperating with the limit hole 403, after the threaded limit pin 504 is screwed into the limit hole 403, the fixed disk 501 and the second connecting ear 402 can be fixed together, thereby limiting the rotation of the sleeve 5. When the torque of the torsion spring 302 needs to be adjusted, the threaded limit pin 504 can be unscrewed to release the restriction on the sleeve 5.

The working principle and use process of the utility model: when in use, the device needs to be placed in a suitable position, as shown in Figure 4. The torsion spring 302 can provide a certain torque for the support arm 3. The support arm 3 is subjected to the torque and will drive the tensioning shaft 1 to rotate upward, thereby lifting the spinning passing through the tensioning shaft 1 and putting it in a tensioned state. The tensioned spinning will also press down the tensioning shaft 1. At this time, the tensioning shaft 1 and the spinning will be in a balanced state. When the spinning becomes loose, the torsion spring 302 will drive the tensioning shaft 1 to continue to move upward, thereby always keeping the tension of the spinning. When the tensioning force applied to the spinning by the tensioning shaft 1 needs to be adjusted, the threaded limit pin 504 needs to be unscrewed to release the restriction on the sleeve tube 5, and then the sleeve tube 5 is rotated to drive the connecting disk 502 to rotate. The torque of the torsion spring 302 can be adjusted by rotating the connecting disk 502.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
