Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a tension detection mechanism for a loom. Background Art

[0002] In the weaving process, the tension of the yarn usually needs to be kept within a stable range. If the tension of the yarn is too small, the fabric may bend or knot. If the tension of the yarn is too large, the fabric may break. Therefore, in the weaving process, it is usually necessary to detect and control the tension of the yarn.

[0003] The Chinese utility model patent, authorization announcement number "CN 220033662 U", discloses a tension detection device and a textile production line, which are composed of a sensor bracket, a pressure sensor, a pressure-bearing piece, a first U-shaped surface, a second U-shaped surface and a third U-shaped surface. During the feeding and movement of the yarn, the vibration generated by the yarn on the pressure-bearing piece and the sensor bracket is small, which can reduce the interference with the pressure sensor and thus improve the reliability of yarn tension detection.

[0004] The above scheme solves the technical problems raised in its background technology, but in practical applications, the above scheme still has certain defects. For example, during the yarn detection process, the above device cannot cool down the second U-shaped surface and the third U-shaped surface in time. Since the yarn is constantly rubbed against the second U-shaped surface and the third U-shaped surface, the second U-shaped surface and the third U-shaped surface will generate heat. If they are not cooled down in time, the yarn will be easily damaged by the friction heat. Utility Model Content

The air flowing to the right enters the middle hollow round rod through the ventilation slot on the left, exchanges heat with the middle hollow round rod, and is discharged from the ventilation slot on the right, thereby cooling the middle hollow round rod.

DETAILED DESCRIPTION

[0026] 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.

[0027] This solution is applied in a loom to detect the tension of the yarn.

[0028] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a tension detection mechanism for a loom, comprising a top plate 1, a mounting plate 101 and side plates 2 fixed on both sides of the top plate 1, a pressure sensor 6 is fixed to the middle of the bottom end of the top plate 1, a sensing part 7 is fixed to the bottom end of the pressure sensor 6, a side hollow round rod 3 is fixed to the bottom end of the side plate 2, a vertical plate 8 is fixed to the bottom end of the sensing part 7, a middle hollow round rod 4 is fixed to the bottom end of the vertical plate 8, a yarn 9 is located on the outside of the side hollow round rod 3 and the middle hollow round rod 4, the angle formed by the yarn 9 at the two side hollow round rods 3 is A, and the angle value of A refers to the technical solution disclosed in the Chinese utility model patent with the authorization number "CN210973376 U".

[0029] The yarn 9 feeding process will generate an extrusion force on the opposite hollow round rod 3 to support the opposite hollow round rod 3 and improve the stability of the device. Figure 4 As shown, a support plate 201 is fixed between the side hollow round rod 3 and the bottom end of the top plate 1 .

[0030] The yarn 9 generates friction with the side hollow round rod 3 during the feeding process, so that heat is generated at the bottom of the side hollow round rod 3. In order to prevent the friction heat from damaging the yarn, Figure 1 and Figure 3 As shown, a refrigeration mechanism 5 for cooling the side hollow round rod 3 is arranged on the outside of the side hollow round rod 3 .

[0031] Specifically, Figure 3 As shown, the refrigeration mechanism 5 includes a partition plate 501 and end caps 502 fixed at both ends of the side hollow round rod 3. The partition plate 501 is preferably made of heat-insulating rubber. The two ends of the partition plate 501 are fixed to the sides of the two end caps 502. The partition plate 501 divides the inner cavity of the side hollow round rod 3 into a top cavity and a bottom cavity.

[0032] Circular through holes connected to the top cavity and the bottom cavity are provided at the top and bottom of the end 502. The two circular through holes of one end 502 are connected by a connecting pipe 509, and the two circular through holes of the other end 502 are respectively fixedly connected with connecting pipes 505, and the two connecting pipes 505 are externally connected to a cooling source, thereby achieving connection between the top cavity and the bottom cavity.

[0033] like Figure 3 As shown, the cooling source includes a cooling box 504 fixed on the outside of the end 502, two connecting pipes 505 are fixedly connected to the cooling box 504, a liquid pump 507 is connected to the tube body of one of the connecting pipes 505, and a plurality of semiconductor cooling plates 506 are fixed on the outside of the cooling box 504. It can be seen that the heat dissipation surface of the semiconductor cooling plate 506 is located on the outside of the cooling box 504, and the cooling surface thereof is located inside the cooling box 504.

[0034] In this solution, the cooling source can also be municipal water. Specifically, when in use, one of the connecting pipes 505 is connected to the municipal water pipe, and the other connecting pipe 505 is a water outlet pipe. In this way, the cooling of the hollow round rod 3 on the cooling water side can also be achieved. However, this will inevitably cause a waste of water resources. Therefore, in this solution, we use semiconductor refrigeration plates 506 to cool the refrigerant to achieve the cooling of the hollow round rod 3 on the opposite side, and the cooling liquid is water.

[0035] Specifically, during detection, the side hollow round rod 3 and the yarn 9 generate heat due to friction, and the controller controls the water pump to start. The cooling water in the refrigeration box 504 (the water is cooled by the semiconductor refrigeration plate 506) enters the bottom cavity through the bottom connecting pipe 505. The cold water entering the bottom cavity absorbs the heat at the bottom of the side hollow round rod 3, thereby cooling the opposite side hollow round rod 3. The heated water returns to the refrigeration box 504 through the top cavity and is cooled by the semiconductor refrigeration plate 506. This cycle achieves continuous cooling of the opposite side hollow round rod 3.

[0036] In order to improve the heat dissipation effect, in another specific embodiment of the present invention, as Figure 3As shown, a plurality of heat sinks 508 are fixed between the inner wall of the bottom end of the side hollow round rod 3 and the partition plate 501. The setting of the heat sink 508 can effectively increase the heat dissipation area of ​​the side hollow round rod 3. In order to prevent the side of the end 502 from fitting with the heat sink 508 so that water cannot flow quickly, an arc groove 503 is opened at the bottom of the end 502, and the arc groove 503 is connected to the bottom cavity.

[0037] like Figure 4 As shown, the yarn 9 is fed from the left side to the right side, and the simultaneous feeding of several yarns 9 will drive the air to move along the feeding direction of the yarn 9. In the scheme, ventilation grooves 401 are opened on both sides of the middle hollow round rod 4. The air flowing to the right enters the middle hollow round rod 4 through the left ventilation groove 401, exchanges heat with the middle hollow round rod 4, and is discharged from the right ventilation groove 401, thereby achieving cooling of the middle hollow round rod 4.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood 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 the scope of the present invention is limited by the attached embodiments and their equivalents.
