[0035] like Figure 1-8As shown, this embodiment provides a yarn feeder assembly fixture, including a base 1, a first positioning block 2, a second positioning block 3, and a positioning element 4. The first positioning block 2 and the second positioning block 3 are detachably fixed to the left side of the top of the base 1. The first positioning block 2 is located in front of the second positioning block 3. A positioning groove 5 for placing the ceramic head of the yarn feeder is formed between the first positioning block 2, the second positioning block 3, and the base 1. The top of the base 1 on the right side of the positioning groove 5 has a first sliding groove 6. The left end of the first sliding groove 6 is opposite to and communicates with the positioning groove 5, and the right end of the first sliding groove 6 penetrates the right side wall of the base 1. The base 1 is detachably fixed with a positioning element 4 for positioning the yarn feeder rod. The positioning end of the positioning element 4 extends into the first sliding groove 6. During assembly, the ceramic head is placed from top to bottom into the positioning groove 5. The shape of the positioning groove 5 matches the ceramic head, and the positioning groove 5 positions the ceramic head, preventing it from shifting during assembly. Then, insert the yarn feeder rod into the first groove 6 from right to left until the left end of the yarn feeder rod abuts against the right end of the ceramic head. The first groove 6 not only facilitates the guiding insertion of the yarn feeder rod but also positions it from both the front and rear sides. Finally, install the positioning piece 4 on the base 1 to position the yarn feeder rod. This completes the positioning of the yarn feeder rod and the ceramic head, preventing them from shifting during assembly and affecting accuracy. After positioning, the yarn feeder rod and ceramic head can be locked with washers and screws to complete the assembly of the yarn feeder. After assembly, remove the positioning piece 4, and then the yarn feeder can be removed. This invention precisely positions the ceramic head and the yarn feeder rod, preventing them from shifting during locking with washers and screws, improving accuracy, and ensuring consistent accuracy for each assembled yarn feeder. Furthermore, the positioning of the ceramic head and the yarn feeder rod requires only simple operation, making it more convenient and faster. The first positioning block 2 and the second positioning block 3 can be detachably installed, allowing for adaptive replacement of different specifications of yarn feeding nozzles as needed, greatly improving applicability.
[0036] The first positioning block 2 has a first locking block 7 fixed to its right side, and the base 1 on the front side of the first slide groove 6 has a first locking groove 8 on its left side. The first locking block 7 engages with the first locking groove 8. The second positioning block 3 has a second locking block 9 fixed to its right side, and the base 1 on the rear side of the first slide groove 6 has a second locking groove 10 on its left side. The second locking block 9 engages with the second locking groove 10. This engaging mechanism allows for detachable connection between the first positioning block 2, the second positioning block 3, and the base 1, facilitating easy assembly and disassembly.
[0037] The first positioning block 2 has a first sliding strip 11 fixed to its bottom. The base 1 has a second sliding groove 12 on its top left side, with the first sliding strip 11 and the second sliding groove 12 slidingly engaged. The second sliding groove 12 is located behind the first sliding groove 6. The second positioning block 3 has a second sliding strip 13 fixed to its bottom, and the base 1 has a third sliding groove 14 on its top left side, with the second sliding strip 13 and the third sliding groove 14 slidingly engaged. The third sliding groove 14 is located in front of the first sliding groove 6. The cooperation of the first sliding strip 11 and the second sliding groove 12 not only guides the installation and removal of the first positioning block 2, but also positions the first positioning block 2 after installation, preventing it from shifting forward or backward and further ensuring the positioning of the ceramic head. Similarly, the cooperation of the second sliding strip 13 and the third sliding groove 14 not only guides the installation and removal of the second positioning block 3, but also positions it after installation, preventing it from shifting forward or backward and further ensuring the positioning of the ceramic head.
[0038] The positioning component 4 includes a mounting bracket 41, a first positioning part 42, a second positioning part 43, a handle 44, and a third locking block 45. The first positioning part 42 is provided on the top of the mounting bracket 41, and the second positioning part 43 is provided on the right inner side wall of the mounting bracket 41. The positioning ends of the first positioning part 42 and the second positioning part 43 both extend into the first sliding groove 6. The handle 44 is fixed to the right outer side wall of the mounting bracket 41, and two third locking blocks 45 are fixed to the right inner side wall of the mounting bracket 41. The front and rear sides of the right end of the base 1 have third locking slots 15, and the third locking blocks 45 engage with the third locking slots 15. The mounting bracket 41 is installed through the cooperation of the third locking blocks 45 and the third locking slots 15, and the installation and disassembly are convenient. The top wall of the yarn feeder rod is positioned by the first positioning part 42, and the upper and lower side walls of the yarn feeder rod are positioned by the bottom wall of the first sliding groove 6. The front and rear side walls of the yarn feeder rod are positioned by the front and rear side walls of the first sliding groove 6. The right side wall of the yarn feeder rod is positioned by the second positioning part 43. The left end wall of the yarn feeder rod abuts against the right end wall of the ceramic head. In this way, the positioning of each wall of the yarn feeder rod is achieved by the first sliding groove 6 combined with the positioning part 4, and the positioning effect is good.
[0039] The first positioning part 42 includes a guide sleeve 421, a guide rod 422, a bolt 423, a first spring 424, and a pressure plate 425. The guide sleeve 421 is fixed to the top of the mounting bracket 41. The bottom end of the guide rod 422 passes through the guide sleeve 421 and is fixed to the pressure plate 425. The first spring 424 is fixed to the top of the pressure plate 425. The top end of the first spring 424 is fixed to the bottom of the guide sleeve 421. The top of the mounting bracket 41 has a threaded hole 411. The bottom end of the bolt 423 passes through the threaded hole 411 and contacts the top of the pressure plate 425. After the mounting bracket 41 is installed on the base 1, the pressure plate 425 extends into the first sliding groove 6 and is located above the yarn feeder rod. Tightening the bolt 423 pushes the pressure plate 425 downward until the pressure plate 425 presses the yarn feeder rod. At this time, the first spring 424 is compressed. When it is necessary to remove the positioning of the yarn feeder rod, loosen bolt 423. Bolt 423 moves upward away from pressure plate 425. Under the action of the first spring 424, it pulls pressure plate 425 upward away from pressure plate 425. The guide rod 422 and guide sleeve 421 ensure the smooth up and down movement of pressure plate 425 and ensure that pressure plate 425 is in a horizontal state to ensure the best positioning effect. Furthermore, the use of the first spring 424 not only ensures the clamping force on the yarn feeder rod, but also can adapt to the positioning of yarn feeder rods of different thicknesses.
[0040] The second positioning part 43 includes a pressure block 431, a second spring 432, a slider 433, and a guide post 434. The guide post 434 is fixed to the right inner wall of the mounting frame 41. The pressure block 431 has a slide rail 435 inside, and the slider 433 is slidably connected in the slide rail 435. The right end of the slider 433 is fixedly connected to the left end of the guide post 434. The left end of the slider 433 is fixed to the second spring 432, and the left end of the second spring 432 is fixed to the left side wall of the slide rail 435. When installing the positioning part 4, the second positioning part 43 is first inserted into the first slide groove 6, and then the mounting frame 41 is pushed from right to left. The mounting frame 41 drives the pressure block 431 to move to the left, so that the pressure block 431 abuts against the right end of the yarn feeder rod. As the mounting frame 41 continues to move to the left, the second spring 432 is compressed, pressing the pressure block 431 tightly against the right end of the yarn feeder rod, ensuring stable positioning of the yarn feeder rod. At this point, the insertion of the third locking block 45 into the third locking slot 15 is also completed. The use of the second spring 432 not only ensures the clamping force on the yarn feeder rod, but also adapts to the positioning of yarn feeder rods of different lengths.
[0041] Rubber pads 46 are fixed to the bottom of the pressure plate 425 and the left side wall of the pressure block 431. The rubber pads 46 not only provide greater friction for better positioning, but also effectively buffer pressure and prevent scratches caused by direct squeezing with the yarn feeder rod.
