Description

Technical Field

[0001] The utility model relates to the technical field of a pricking roller tension regulating mechanism, in particular to a tension regulating mechanism and a pricking roller hanging angle. Background Art

[0002] The water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. The frictional traction of water jet weft insertion on the weft yarn is greater than that of air jet weft insertion, and the diffusion is small. It is suitable for the weft insertion of smooth-surfaced synthetic fibers, glass fibers and other filaments. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity during weaving.

[0003] In the prior art, the pricking roller needs to adjust the tension in both the winding and unwinding process to obtain a complete and smooth product. The detection is performed by a detection device, and the tension is adjusted by an adjusting roller.

[0004] However, when a traditional water jet loom is used in conjunction with a pricking roller, not only does it need to repeatedly adjust the tension to achieve an ideal effect, but the pricking roller also needs to be removed from the circular shaft for adjustment, which is very labor-intensive. To this end, the utility model proposes a tension adjustment mechanism and a pricking roller hanging angle to solve the above problems. Utility Model Content

[0026] When the tension adjustment mechanism is in use, the tension of the water jet loom fabric is adjusted by adjusting the height of the roller 10 moving up and down in the adjusting groove 12. The downward pulling force of the connecting spring 132 can avoid the problem of the adjusting roller 10 being offset in the adjusting groove 12, meeting the actual production needs. The setting of the U-shaped hanging angle 7 replaces the traditional round hole through the shaft. When the pricking roller 9 needs to be disassembled, the fixing bolt 602 can be loosened and then the electric push rod 6 can be started to drive the support shaft 603 to move backward. One end of the pricking roller 9 is disengaged from the positioning groove 17, so that the pricking roller 9 can be directly taken out from the U-shaped hanging angle 7, saving a lot of time and manpower. Embodiment 2

[0027] On the basis of the first embodiment, in order to facilitate the disassembly of the pricking roller 9, a U-shaped hanging angle 7 is provided, and a fixing platform 11 is provided on the side of the support frame 2. The fixing platform 11 is an "L"-shaped plate structure as a whole. When the pricking roller 9 is installed on the U-shaped hanging angle 7, the fixing platform 11 can support one end of the pricking roller 9. A positioning groove 17 is provided on the end surface of the positioning shaft 601. One end of the pricking roller 9 can be inserted into the positioning groove 17 and fixed with a fixing bolt 602. The electric push rod 6 is fixedly connected to the bracket 16;

[0028] The U-shaped hanging angle 7 is used to replace the traditional round hole through-shaft. When the pricking roller 9 needs to be removed, the fixing bolt 602 can be directly loosened, and then the electric push rod 6 can drive the supporting shaft 603 and the positioning shaft 601 to move backward, so that the pricking roller 9 is disengaged from the positioning groove 17. Then the pricking roller 9 can be taken out of the U-shaped hanging angle 7. The setting of the fixing platform 11 can support the other end of the pricking roller 9 when one end of the pricking roller 9 is inserted into the positioning groove 17, so as to avoid the problem of displacement of the pricking roller 9 when the positioning groove 17 is pushed. Embodiment 3

[0029] On the basis of the second embodiment, in order to effectively adjust the tension, an adjusting groove 12 is provided, a connecting spring 132 can provide a downward pulling force for the adjusting roller 10, one end of the adjusting roller 10 can be inserted into the adjusting groove 12, the connecting spring 132 can be squeezed up and down in the frame 13, a card slot is provided on the inner surface of the adjusting groove 12, one end of the adjusting roller 10 can be inserted into the card slot, the adjusting groove 12 has a plurality of adjustable gears, and the adjusting roller 10 can be moved in the adjusting groove 12 by different positions in the adjusting groove 12 so that the adjusting roller 10 The height can be adjusted, the support rod 14 is fixed to the side of the support frame 2, the surface of the base 131 and the adjusting roller 10 are wound and fixed by iron wire, when the adjusting roller 10 is disassembled, the adjusting roller 10 can be taken out from the adjusting slot 12, the motor 3 can drive the smooth wheel 4 to rotate, the surface of the support shaft 603 is also sleeved with a smooth wheel 4, and the two groups of smooth wheels 4 are driven by a rotating belt 5, so that the rotating belt 5 can drive the support shaft 603 and the rotating rod 15 to rotate, so that the pricking roller 9 placed in the U-shaped hanging angle 7 can rotate;

[0030] The adjusting roller 10 moves up and down in the adjusting groove 12 to adjust the pressure. The adjusting roller 10 can be moved and positioned in the adjusting groove 12 to adjust the height of the adjusting roller 10. The tension of the cloth surface can be adjusted by changing the height of the adjusting roller 10, thereby realizing the tension adjustment problem, which meets the tension required by actual production and is very convenient. The setting of the connecting spring 132 can provide a downward pulling force to the adjusting roller 10, so that the adjusting roller 10 is fixed in the adjusting groove 12 in cooperation with the card slot opened in the adjusting groove 12 without the problem of offset. When it is necessary to rotate the pricking roller 9, the motor 3 can be directly started to make the smooth wheel 4 cooperate with the rotating belt 5 to drive the support shaft 603 to rotate, so that the pricking roller 9 can be rotated. The setting of the bearing 8 can avoid the problem that the electric push rod 6 will be driven to rotate when the support shaft 603 is rotated.

[0031] In actual use, the tension of the cloth surface of the water jet loom is adjusted by adjusting the height of the roller 10 moving up and down in the adjusting groove 12. The downward pulling force of the connecting spring 132 can avoid the problem of the adjusting roller 10 being offset in the adjusting groove 12, which meets the actual production needs. The setting of the U-shaped hanging angle 7 replaces the traditional round hole through-shaft. When it is necessary to disassemble the pricking roller 9, the fixing bolt 602 can be loosened and then the electric push rod 6 can be started to drive the supporting shaft 603 to move backward. One end of the pricking roller 9 is disengaged from the positioning groove 17, so that the pricking roller 9 can be directly taken out from the U-shaped hanging angle 7, saving a lot of time and manpower. In this way, it is avoided that when the traditional water jet loom is used in conjunction with the pricking roller 9, not only the tension needs to be repeatedly adjusted to the ideal effect, but also the pricking roller 9 needs to be removed from the round through-shaft for adjustment when disassembling, which is very labor-intensive.

[0032] Although 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.
