Description

Technical Field

[0001] This utility model relates to the field of textile processing equipment, and more specifically, it relates to a yarn false twisting machine. Background Technology

[0002] A false twisting machine is an important textile processing device. It utilizes the internal friction and tension of the yarn to twist the yarn itself, thereby creating twist. This process mainly relies on the friction between the false twisting element and the yarn, causing the yarn to undergo false twisting deformation under the action of traction force. The false twisting machine can operate continuously. Existing false twisting machines typically include three rotating shafts, each with several friction plates stacked sequentially on adjacent shafts. Support blocks are provided between the friction plates for support. When the friction plates at the bottom or middle are damaged, it is necessary to remove the friction plates one by one from the rotating shafts, which is a cumbersome and inconvenient operation.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a yarn false twisting machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a yarn false twisting machine, comprising a base, a rotating shaft, a support block and a plurality of friction plates, wherein the friction plates include a connecting block and a plurality of friction blocks, the plurality of friction blocks being detachably connected to the connecting block, the connecting block having a groove communicating with its outer wall, and the friction blocks having protrusions fixedly connected to them that can be embedded in the grooves, wherein when the protrusions are embedded in the grooves, the sidewalls of two adjacent friction blocks abut against each other, and the diameter of the connecting block being larger than the diameter of the support block.

[0006] The present invention is further configured such that: the friction plate is provided with two baffles for covering the groove, and a through hole for accommodating the rotating shaft is formed between the two baffles, the diameter of the through hole is equal to the diameter of the support block, and the outer diameter of the baffle is equal to the diameter of the connecting block.

[0007] The present invention is further configured such that: each of the two baffles has a plurality of locking blocks and a slot for accommodating the locking blocks on one side facing each other, and one baffle is fixed to the other baffle by locking blocks into the slots on the adjacent baffle.

[0008] The present invention is further configured such that the groove is a dovetail groove.

[0009] The present invention is further configured such that: two protrusions are provided, and the two protrusions are symmetrically arranged on the friction block.

[0010] The present invention is further configured such that the friction block has rounded corners.

[0011] The present invention is further configured such that a limiting block for the friction plate and the support block to abut against each other is detachably connected to the rotating shaft.

[0012] In summary, this utility model has the following beneficial effects: Through the detachable friction block design, operators only need to apply opposite forces to the two friction blocks when disassembling and replacing worn friction blocks, causing them to move in opposite directions. Once the protrusion disengages from the groove, a quick disassembly operation can be achieved. This operation greatly improves maintenance efficiency, effectively reduces downtime caused by replacing friction blocks, and thus improves overall production efficiency. Because the diameter of the connecting block is larger than the diameter of the support block, the protrusion will not interfere with the support block when disengaging from the groove, thereby ensuring a smooth disassembly process and guaranteeing the efficiency of operator replacement.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] A yarn false twisting machine, such as Figure 1As shown, the device includes a base 1, a rotating shaft 2, a support block 3, and several friction plates 4. Specifically, the base 1, rotating shaft 2, and support block 3 are all made of stainless steel, while the friction plates 4 are made of polyurethane. Since stainless steel has high resistance to most corrosive environments, this allows the false twisting machine to operate stably for a long time in humid or dusty environments, reducing maintenance and replacement costs caused by corrosion. At the same time, stainless steel has excellent mechanical strength and can withstand various stresses and vibrations generated during the operation of the false twisting machine, ensuring the stability and reliability of the equipment. Polyurethane has excellent frictional properties and can provide a stable coefficient of friction, ensuring that the yarn can be evenly stressed during the false twisting process, improving the false twisting effect. In addition, polyurethane material causes less wear on the yarn, ensuring the strength of the yarn.

[0020] Specifically, the friction plate 4 includes a connecting block 5 and two friction blocks 6, with the two friction blocks 6 detachably connected to the connecting block 5. The connecting block 5 has a groove 13 communicating with its outer wall. A protrusion 12, which can be embedded in the groove 13, is fixedly connected to each friction block 6. When the protrusion 12 is embedded in the groove 13, the sidewalls of adjacent friction blocks 6 abut against each other. The diameter of the connecting block 5 is larger than the diameter of the support block 3. Through the detachable design of the friction blocks 6, when disassembling and replacing worn friction blocks 6, the operator only needs to apply opposite forces to the two friction blocks 6, causing them to move in opposite directions. Once the protrusion 12 disengages from the groove 13, a quick disassembly operation can be achieved. This operation greatly improves maintenance efficiency, effectively reduces downtime caused by replacing the friction blocks 6, and thus improves... To improve overall production efficiency, since the diameter of the connecting block 5 is larger than that of the support block 3, the protrusion 12 will not interfere with the support block 3 when it is disengaged from the groove 13, thus ensuring the smooth disassembly process and the efficiency of the operators in replacement. Furthermore, the groove 13 is a dovetail groove, and there are two protrusions 12, which are symmetrically arranged on the friction block 6. The dovetail groove design allows the protrusion 12 to be firmly positioned in the groove 13, making it difficult to loosen or fall off, thus ensuring the stability and reliability of the friction plate 4 during operation. The two symmetrically arranged protrusions 12 make the friction block 6 more evenly stressed, reducing the problem of uneven wear caused by uneven stress. The symmetrical design also enhances the structural stability of the friction block 6 and improves its service life.

[0021] The friction plate 4 is provided with two baffles 7 for covering the groove 13. A through hole 8 is formed between the two baffles 7 to accommodate the rotating shaft 2. The diameter of the through hole 8 is equal to the diameter of the support block 3, and the outer diameter of the baffle 7 is equal to the diameter of the connecting block 5. The design of the baffle 7 effectively covers the groove 13 and protects the connection between the friction block 6 and the protrusion 12. During the operation of the yarn false twisting machine, this can prevent external impurities or dust from entering the groove 13 and affecting the normal operation of the friction block 6 and the protrusion 12, thereby ensuring the stability and reliability of the friction plate 4. Since the diameter of the through hole 8 is equal to the diameter of the support block 3, the baffle 7 is tightly connected to the support block 3, ensuring the stability of the baffle 7. And the outer diameter of the baffle 7 is equal to the diameter of the connecting block 5, so that the baffle 7 can completely block the groove 13, preventing dust and impurities from entering the groove 13 and extending the service life of the false twisting machine.

[0022] Furthermore, each of the two baffles 7 has several locking blocks 9 and slots 10 for receiving the locking blocks 9 on its facing side. One baffle 7 is fixed to the other baffle 7 by the locking blocks 9 being inserted into the slots 10 on the adjacent baffle 7. By using the fixing method of locking blocks 9 and slots 10, the installation of the baffles 7 becomes simple and quick. The operator only needs to align the locking blocks 9 with the slots 10 and press gently to fix them, without the need for additional tools or complicated operations. This greatly shortens the installation time and improves work efficiency. Moreover, the tight fit between the locking blocks 9 and the slots 10 ensures the fixed stability between the baffles 7. Once the locking blocks 9 are inserted into the slots 10, a firm connection is formed between the baffles 7, which is not easy to loosen or fall off. This stability helps to prevent equipment failure or performance degradation caused by the displacement or fall off of the baffles 7.

[0023] A limiting block 11 is detachably connected to the rotating shaft 2 for the friction plate 4 and the support block 3 to abut against each other. The friction block 6 has rounded corners. One side of the limiting block 11 has three round holes for the insertion of the rotating shaft 2. The other side of the limiting block 11 is fixedly connected to the lifting machine. People can adjust the height of the limiting block 11 to allow the rotating shaft to be inserted into or removed from the round holes, thereby achieving the effect of limiting and fixing the limiting block 11. The design of the limiting block 11 allows the friction plate 4 to be tightly pressed against the support block 3. With its detachable connection, the limiting block 11 can be installed or removed as needed, thereby adjusting the gap between the friction plate 4 and the support block 3 to ensure that they always maintain close contact during operation. This close contact helps to improve friction efficiency, reduce yarn slippage during false twisting, and thus improve yarn quality and false twisting effect. The rounded corner design helps to reduce wear and resistance of the friction block 6 during operation. The rounded corners make the contact between the friction block 6 and the yarn smoother, reducing wear and breakage caused by sharp edges and corners, thereby extending the service life of the friction block 6 and improving the overall performance and stability of the equipment.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
