Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 As shown, a yarn tension adjustment device for a yarn frame includes a yarn frame 1. Several fixing mechanisms 2 are installed on the yarn frame 1. A locking plate 3 is engaged with each fixing mechanism 2. A guide mechanism 4 is fixed to the locking plate 3. A bobbin frame 5 is rotatably mounted on the locking plate 3. An adjustment mechanism 6 is provided between two guide mechanisms 4. The adjustment mechanism 6 includes a tension spring 606 and a mounting block 607. The mounting block 607 and a rod 601 are fixedly connected to the locking plate 3. A rotating block 602 is rotatably connected to the rod 601. A swing rod 603 is fixedly connected to the rotating block 602. A tension spring 606 is fixedly installed between the swing rod 603 and the mounting block 607. A connecting rod 604 is fixedly installed at the end of the swing rod 603. A pressure wheel 605 is rotatably connected to the connecting rod 604.

[0025] As a technical optimization of this utility model, the swing rod 603 is inclined, and the connecting rod 604 is located at the end of the swing rod 603 away from the rotating block 602. The pressure wheel 605 is affected by the change in yarn tension, which can cause the connecting rod 604 to drive the swing rod 603 to rotate.

[0026] As a technical optimization of this utility model, the fixing mechanism 2 includes a locking rod 202 and a locking groove 204. A plurality of locking grooves 204 are provided at equal intervals on the weaving frame 1. The locking rod 202 is fixedly installed in the locking groove 204. A locking plate 3 is engaged with the locking rod 202. A positioning block 203 is threadedly connected to the locking rod 202. Two sets of pads 201 are fixedly installed at the bottom end of the weaving frame 1. When the locking plate 3 is engaged with the side wall of the locking rod 202, the positioning block 203 can limit the locking plate 3.

[0027] As a technical optimization of this utility model, the card plate 3 is engaged with the weaving frame 1, and the positioning block 203 is set in a regular hexagonal structure. The setting of the card plate 3 makes it convenient for the operator to install the guide wheel 402 and the pressing wheel 605.

[0028] As a technical optimization of this utility model, the height of the card plate 3 is less than the height of the card slot 204, and the height of the card rod 202 is equal to the height of the card slot 204. The card rod 202 limits the card plate 3, so that the card plate 3 can be fixed in the weaving frame 1.

[0029] As a technical optimization of this utility model, the guiding mechanism 4 includes a support rod 401 and a guide wheel 402. The support rod 401 is fixedly connected to the clamping plate 3, and a connecting shaft 403 is fixedly installed on the support rod 401. The guide wheel 402 is rotatably connected to the connecting shaft 403. During the yarn conveying process, the guide wheel 402 can be rotated along the connecting shaft 403.

[0030] As a technical optimization of this utility model, the two support rods 401 are symmetrically arranged about the pressing wheel 605, and the diameter of the support rod 401 is larger than the diameter of the connecting shaft 403. The pressing wheel 605 contacts the yarn, and the tension of the yarn can be adjusted.

[0031] As a technical optimization of this utility model, both the guide wheel 402 and the pressure wheel 605 are arranged in an "I" shape, and the diameters of the guide wheel 402 and the pressure wheel 605 are equal. The tension of the yarn can be adjusted during the yarn transmission process through the guide wheel 402 and the pressure wheel 605.

[0032] As a technical optimization of this utility model, the pressing wheel 605 is located in the middle of the two guide wheels 402, and the swing rod 603 is located at the bottom of the guide wheel 402. The pressing wheel 605 can adjust the rotation angle of the swing rod 603 according to the change of yarn tension.

[0033] In use, the operator first aligns the insertion hole on the card plate 3 with the card rod 202 fixed on the weaving frame 1. When the card plate 3 is engaged with the side wall of the card rod 202, it can abut against the weaving frame 1. Then, the operator uses a tool to rotate the positioning block 203, which can fix the card plate 3 inside the weaving frame 1. Next, the operator can install the yarn bobbin onto the bobbin frame 5 on the card plate 3. The bobbin frame 5 is rotatably connected to the card plate 3. During yarn feeding, the bobbin frame 5 can rotate along the side wall of the card plate 3, which facilitates yarn feeding. One end of the yarn is wound onto the guide wheel 402 and the pressure wheel 605. During yarn feeding, the yarn tension changes, and the pressure wheel 605 is affected by the yarn. The pressure wheel 605 moves along the side of the connecting rod 604 fixed on the swing arm 603. The wall rotates, and a rotating block 602 is fixed to one end of the swing rod 603 away from the pressure roller 605. When the swing rod 603 rotates, the rotating block 602 can rotate along the insertion rod 601 fixed on the clamping plate 3. A tension spring 606 is provided between the swing rod 603 and the mounting block 607 fixed on the clamping plate 3. When the swing rod 603 rotates, the tension spring 606 can be in an open or closed state. The tension spring 606 can evenly adjust the tension of the yarn through its own elasticity, ensuring that the yarn maintains stable tension during the weaving process and avoiding yarn breakage or fabric defects caused by uneven tension. The yarn slides along the guide wheel 402, which can make the guide wheel 402 rotate along the connecting shaft 403. The connecting shaft 403 is fixedly connected to the support rod 401. The support rod 401 supports the connecting shaft 403, which can improve the guiding effect of the guide wheel 402 on the yarn.
