Description
Technical Field
[0001] This utility model relates to the field of covering yarn machines, specifically a yarn tube structure. Background Technology
[0002] Yarn tubes are widely used auxiliary equipment in the textile industry, mainly used for winding yarn to facilitate continuous operation of textile machinery. Traditional yarn tubes typically consist of a tube body and baffles fixed at both ends. The baffles prevent the yarn from falling off the ends of the tube body during winding or unwinding.
[0003] In practical use, yarn inevitably gets tangled at the joint between the tube and the baffle plate, a phenomenon commonly known as "yarn entanglement." This type of entanglement easily gets stuck in the gap between the baffle plate and the tube, making cleaning extremely difficult. Operators often need to use sharp tools to painstakingly remove it, a process that is not only inefficient and labor-intensive but also prone to scratching, prying, or even damaging the yarn tube or baffle plate itself, leading to premature scrapping of the entire yarn tube and increased production costs. Therefore, for thorough cleaning or maintenance of the yarn tube, it is often necessary to remove the baffle plate.
[0004] However, in traditional yarn tube structures, the baffle and tube body are usually glued together. While this method is convenient, it cannot be disassembled without damage once glued. To address this, an interference fit connection is currently used. The interference fit relies on the compressive stress and friction generated by the outer diameter of the baffle insert being slightly larger than the inner diameter of the tube for fixation. Although it can be disassembled, this rigid connection method makes disassembly and assembly extremely difficult: installation requires a huge impact or pressure, which can easily cause micro-cracks and other internal damage to the plastic tube body or insert. Disassembly is even more troublesome, requiring the use of tools to pry it from the inside or knock it from the outside. The operation is rather rough. When cleaning the yarn entanglement or replacing the baffle, this violent disassembly can easily cause permanent plastic deformation, cracking, or even chipping at the end of the insert or tube body, thus causing the connection to fail, resulting in component damage or even complete scrapping. Utility Model Content
[0005] The purpose of this utility model is to provide a yarn tube structure to solve the above-mentioned problems.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a yarn tube structure, including a tube body and baffles detachably installed at both ends of the tube body; The baffle includes a disc body and a tube, the tube being inserted into the end of the tube body, and the tube being provided with several locking mechanisms; The locking mechanism includes a latching member movably disposed on the side wall of the insertion tube. The latching member includes a locking part that protrudes from the outer side wall of the insertion tube and an operating part that protrudes from the inner side wall of the insertion tube. A slot for the locking part to engage is provided on the side wall of the tube end. A first elastic unit and a second elastic unit are provided between the latching member and the insertion tube. The first elastic unit acts on the upper side of the latching member to provide an elastic force that moves the latching member upward so that the locking part protrudes from the outer wall of the insertion tube in its natural state. The second elastic unit is located on the lower side of the latching member to provide an elastic force that moves the latching member downward so that the operating part protrudes from the inner wall of the insertion tube in its natural state. A force-applying groove is provided on the side wall of the operating part.
[0007] As a further feature of this invention, several through grooves are vertically formed on the side wall of the insertion tube, and the fastener can slide up and down within the through grooves.
[0008] As a further feature of this utility model, the two side walls of the through groove are provided with vertical sliding grooves, and the two sides of the buckle are provided with sliders that are slidably connected inside the sliding grooves.
[0009] As a further feature of this invention, the first elastic unit is a tension spring, one end of which is fixedly connected to the inner bottom wall of the slide groove, and the other end is connected to the slider. The second elastic unit is a compression spring, one end of which is fixedly connected to the inner top wall of the slide groove, and the other end is connected to the slider.
[0010] As a further feature of this invention, each of the slide grooves is provided with a guide rod, which passes through the first elastic unit, the slider, and the second elastic unit in sequence.
[0011] As a further feature of this invention, the tube body, disc body, and insertion tube are all made of PA material.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention eliminates the need for sharp tools to pry or knock; a simple downward pull is all that's required to unlock the device. This significantly reduces disassembly difficulty, labor intensity, and operation time, making the cleaning of tangled yarn and the removal and installation of the baffle plate extremely simple. Furthermore, because the disassembly process is a gentle mechanical action rather than a violent separation, it effectively avoids permanent damage, cracking, or scrapping of plastic parts caused by prying, scratching, knocking deformation, or micro-cracks. This greatly reduces the risk of component damage and effectively extends the service life of the yarn tube structure. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0016] Please see Figure 1-6As shown, a yarn tube structure includes a tube body 1 and baffles detachably installed at both ends of the tube body 1. The tube body 1 is through the tube body 1. The baffles include a disc body 2 and an insert tube 3. The insert tube 3 is used to insert into the end of the tube body 1. The tube body 1, disc body 2, and insert tube 3 are all made of PA material, which has high strength and good wear resistance, thus giving the yarn tube structure good durability. Several locking mechanisms are provided on the insert tube 3. The locking mechanisms include latching parts movably disposed on the side wall of the insert tube 3. The latching parts include a locking part 4 that can protrude from the outer side wall of the insert tube 3 and an operating part 5 that can protrude from the inner side wall of the insert tube 3. A slot 6 for the locking part 4 to be engaged is provided on the side wall of the end of the tube body 1. A first elastic unit 7 and a second elastic unit 8 are provided between the latching parts and the insert tube 3. The first elastic unit... 7 acts on the upper side of the buckle to provide an elastic force that moves the buckle upward, so that the locking part 4 protrudes from the outer wall of the insertion tube 3 in its natural state. The second elastic unit 8 is used on the lower side of the buckle to provide an elastic force that moves the buckle downward, so that the operating part 5 protrudes from the inner wall of the insertion tube 3 in its natural state. A force-applying groove 9 is provided on the side wall of the operating part 5. When the yarn tube structure is installed, the insertion tube 3 can be aligned with the end of the tube body 1 and inserted. During the insertion process, the locking part 4 on the outer wall of the insertion tube 3 will contact the inner wall of the tube body 1 and be squeezed. At this time, the squeezing force will overcome the elastic force of the first elastic unit 7, forcing the entire buckle to move downward, so that the locking part 4 retracts into the through groove 10 of the insertion tube 3, thereby smoothly sliding into the tube body 1. When the insertion tube 3 is inserted... When the locking part 4 is properly aligned with the slot 6 on the side wall of the tube body 1, the elastic force of the first elastic unit 7 is released, immediately pushing the buckle upward to reset, causing the locking part 4 to quickly pop out and engage in the slot 6, forming a mechanical interlock. This securely locks the baffle onto the tube body 1. In this state, the yarn tube needs to be fitted onto the spindle of the textile machine. The spindle will be inserted into the tube 3, and its outer wall will naturally press down the operating part 5 protruding from the inner side wall of the tube 3, keeping it in a retracted state. This allows the locking part 4 to continue to push upward, ensuring the smoothness of the inner wall of the tube 3, not affecting the normal high-speed rotation of the yarn tube on the spindle, and effectively improving the locking stability. When it is necessary to clean the tangled yarn, the yarn tube structure can be removed from the spindle first. After the spindle is pulled out, the control mechanism is lost. The pressure on the operating part 5 releases the elastic force of the second elastic unit 8, pushing the locking member downwards. This causes the operating part 5 and its force-applying groove 9 to protrude again from the inner wall of the insertion tube 3. The operator can then insert a special tool into the insertion tube 3, embed it into the force-applying groove 9, and pull the operating part 5 downwards. This downward force overcomes the elastic force of the first elastic unit 7, causing the entire locking member to move downwards, thereby pulling the locking part 4 out of the slot 6 of the tube body 1 and retracting it into the through groove 10. The locked mechanical connection is immediately released, allowing the insertion tube 3 to be pulled out from the end of the tube body 1, thus disassembling the baffle and facilitating the cleaning of the wound yarn. With the above setup, there is no need for violent prying or knocking with sharp tools; a simple downward pulling action is sufficient to release the lock.This significantly reduces disassembly difficulty, labor intensity, and operation time, making the cleaning of tangled yarn and the removal and installation of the baffle plate extremely simple. Furthermore, because the disassembly process involves gentle mechanical movements rather than forceful separation, it effectively avoids permanent damage, cracking, or scrapping of plastic parts caused by prying, scratching, hammering deformation, or micro-cracks. This greatly reduces the risk of component damage and effectively extends the service life of the yarn tube structure.
[0017] Please see Figure 3-6 As shown, several vertical slots 10 are formed on the side wall of the insertion tube 3, and the latching component can slide up and down within the slots 10. The vertical slots 10 provide precise guidance and a stable movement trajectory for the latching component, ensuring that it does not skew or jam when locking and unlocking, thus improving the reliability and service life of the locking mechanism. Sliding grooves 11 are formed vertically on both sides of the slots 10, and sliders 12 are slidably connected to the sliding grooves 11 on both sides of the latching component. The cooperation between the sliders 12 and the sliding grooves 11 greatly enhances the stability and smoothness of the latching component during sliding, preventing it from wobbling back and forth or left and right within the slots 10, making the locking action more reliable and the unlocking operation smoother. The first elastic unit 7 is a tension spring, and one end of the first elastic unit 7 is fixedly connected to the inner bottom wall of the sliding groove 11. One end is connected to the slider 12. The second elastic unit 8 is a compression spring, and one end of the second elastic unit 8 is fixedly connected to the inner top wall of the slide groove 11, while the other end is connected to the slider 12. It adopts a combination of tension spring and compression spring, which is simple and compact in structure. It can efficiently provide elastic forces in opposite directions, which work together on the buckle to achieve a stable bidirectional protrusion in the natural state. Guide rods 13 are provided inside the slide groove 11, and the guide rods 13 pass through the first elastic unit 7, the slider 12 and the second elastic unit 8 in sequence. By setting the guide rods 13, common support and guidance are provided for the first elastic unit 7, the slider 12 and the second elastic unit 8, thereby preventing the first elastic unit 7 and the second elastic unit 8 from bending or twisting during compression and tension, ensuring that the elastic force always acts in a straight line, and making the slider 12 slide more smoothly.
