Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and more specifically, it relates to a locking and releasing device that facilitates insertion and removal of bobbins. Background Technology

[0002] The winding machine is one of the essential pieces of equipment in the post-spinning and preparation process. It is mainly used to wind yarn into cones. By processing the bobbins or skeins from the spinning department into cones that meet certain requirements on the winding machine, the production process of cones requires placing the bobbins onto the rotating shaft of the winding machine. The rotating shaft drives the bobbins to rotate, thus completing the purpose of winding the yarn and forming cones.

[0003] Existing winding machines have an inner support device on their rotating shaft, which abuts against the inner wall of the bobbin to limit its movement. At the same time, a spring-loaded device is slidably connected to the winding machine to open the inner support device. When it is necessary to change the wound yarn bobbin, the existing winding machine requires the worker to press the spring-loaded device with one hand and lift the bobbin with the other, which is very inconvenient. Similarly, when a new bobbin needs to be inserted, the spring-loaded device must be pressed down first before the bobbin can be inserted, which increases the worker's workload and affects the efficiency of bobbin replacement.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a locking and releasing device that facilitates insertion and removal of the cylinder in order to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model embodiment is achieved through the following technical solution: a locking and releasing device for easy insertion and removal of the sleeve, including a mounting base and a rotating shaft that rotatably cooperates with the mounting base, a spring block being movably connected to the rotating shaft, a spring being provided between the spring block and the mounting base, a fixing ring being fixedly connected to the spring block, a limiting structure being installed on one side of the mounting base, the limiting structure having a rotatably configured limiting block, and when the spring block moves close to the mounting base, the limiting block hooks the fixing ring.

[0007] The present invention is further configured such that: the limiting structure includes a connecting plate disposed on one side of the mounting base and a limiting block rotatably disposed on the connecting plate; an eccentrically disposed support rod is fixedly connected to the limiting block; the support rod rotatably engages with the connecting plate; the limiting block has a first hook-shaped limiting part and a second hook-shaped limiting part; the first hook-shaped limiting part is provided with a first guide surface and a first abutting surface; the second hook-shaped limiting part is provided with a second abutting surface; when the rebound block moves toward the mounting base, the fixing ring contacts the first guide surface and pushes the limiting block to rotate; when the fixing ring separates from the first guide surface and rebounds, the fixing ring abuts against the first abutting surface and simultaneously the second abutting surface abuts against the connecting plate.

[0008] The present invention is further configured such that the included angle between the first abutting surface and the second abutting surface is 80 degrees to 100 degrees.

[0009] The present invention is further configured such that: the fixing ring is provided with a through groove for the limiting block to pass through, and the fixing rings on both sides of the through groove are provided with a second guide surface.

[0010] The present invention is further configured such that: a slot is provided on one side of the mounting base, the connecting plate is located in the slot and the connecting plate is fixed to the slot by a limiting screw.

[0011] The present invention is further configured such that: a groove is provided inside the rebound block, a rolling bearing is provided between the mounting base and the rotating shaft, and the two ends of the spring abut against the groove and the rolling bearing respectively.

[0012] The present invention is further configured such that: a first groove is provided on the rotating shaft, one side of the rolling bearing is engaged with the first groove, a second groove is provided in the mounting base, a limit ring is engaged in the second groove, and the side of the rolling bearing away from the first groove abuts against the limit ring.

[0013] In summary, this utility model has the following beneficial effects:

[0014] By installing a connecting plate and a limiting block that rotates with the connecting plate on the mounting base, when the completed yarn package needs to be removed, pressing the yarn package causes the spring block to slide down. During the downward movement of the spring block, it abuts against the first guide surface of the limiting block, thereby causing the limiting block to rotate on the connecting plate, allowing the spring block to slide smoothly. When the spring block separates from the limiting block, the limiting block will rotate upward under the action of gravity. At this time, releasing the force on the spring block will cause the fixing ring on the spring block to abut against the contact surface of the limiting block, thereby limiting the spring block and preventing it from sliding upward. This makes it easier for workers to remove the completed yarn package and insert a new yarn package. After the yarn package is replaced, simply rotating the spring block will cause the limiting block to disengage from the spring block through the slot and re-abut against the inner support device, greatly reducing the workload of workers and making yarn package replacement more convenient and effectively improving the efficiency of yarn package replacement.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] In one possible embodiment, please refer to Figure 1 , Figure 2 and Figure 3As shown, a locking device for easy insertion and removal of the cylinder includes a mounting base 1 and a rotating shaft 2 that rotates with the mounting base 1. A spring block 3 is movably connected to the rotating shaft 2. A spring 4 is provided between the spring block 3 and the mounting base 1. The spring 4 can rebound the spring block 3, causing it to rebound and abut against the inner support block. A groove 302 is provided inside the spring block 3. A rolling bearing 8 is provided between the mounting base 1 and the rotating shaft 2. The two ends of the spring 4 abut against the groove 302 and the rolling bearing 8, respectively. By providing the rolling bearing 8, the mounting base 1 will not affect the rotation of the rotating shaft 2. The groove 302 can limit the spring 4 and prevent the spring 4 from disengaging from the spring block 3 and the rolling bearing 8.

[0021] For further details, please refer to Figure 1 , Figure 2 and Figure 3 As shown, a first groove 201 is provided on the rotating shaft 2, and one side of the rolling bearing 8 is engaged with the first groove 201. A second groove 102 is provided in the mounting base 1, and a limiting ring 9 is engaged in the second groove 102. The side of the rolling bearing 8 away from the first groove 201 abuts against the limiting ring 9, so that both sides of the rolling bearing 8 abut against the first groove 201 and the limiting ring 9 respectively. The limiting ring 9 and the first groove 201 can support the rolling bearing 8 and prevent the rolling bearing 8 from sliding down.

[0022] For further details, please refer to Figure 1 , Figure 2 and Figure 3 As shown, a limiting structure is installed on one side of the mounting base 1. The limiting structure includes a connecting plate 5 and a limiting block 6 rotatably mounted on the connecting plate 5. A slot 101 is provided on one side of the mounting base 1. The connecting plate 5 is located in the slot 101 and the connecting plate 5 is fixed to the slot 101 by a limiting screw 7. That is, the connecting plate 5 is fixedly installed in the slot 101 of the mounting base 1 by the limiting screw 7. A threaded hole is provided in the slot 101 that is threaded to the limiting screw 7. The limiting block 6 is used to limit the rebound block 3. When the rebound block 3 moves close to the mounting base 1, the limiting block 6 hooks the fixing ring 3. An eccentrically mounted support rod 601 is fixedly connected to the limiting block 6. The support rod 601 is rotatably engaged with the connecting plate 5.

[0023] For further details, please refer to Figure 1 , Figure 2 and Figure 3As shown, the limiting block 6 has a first hook-shaped limiting part 602 and a second hook-shaped limiting part 603. The first hook-shaped limiting part 602 is provided with a first guide surface 6021 and a first abutting surface 6022. When the spring block 3 moves toward the mounting base 1, the fixing ring 3 contacts the first guide surface 6021 and pushes the limiting block 6 to rotate. That is, when it is necessary to remove the completed yarn package, the spring block 3 is driven to slide down by pressing the yarn package. When the spring block 3 slides down, it will abut against the first guide surface 6021, causing the spring block 3 to rotate downward, so that the spring block 3 can slide smoothly. The second hook-shaped limiting part 603 is provided with a second abutting surface 6031. When the fixing ring 3 separates from the first guide surface 6021 and springs back, the fixing ring 3 abuts against the first abutting surface 6022 and at the same time the second abutting surface 6031 abuts against the connecting plate 5. When the spring block 3 continues to slide down and separates from the limiting block 6, the limiting block 6 will rotate upward under the action of the second hook-shaped limiting part 603. When the second abutting surface 6031 abuts against the connecting plate 5, it stops rotating. The included angle between the first abutting surface 6022 and the second abutting surface 6031 is 80 degrees-100 degrees. A fixing ring 301 is fixedly connected to the spring block 3. After the fixing ring 301 slides, it abuts against the first abutting surface 6021. After the force on the spring block 3 is released, the spring block 3 will rebound under the action of the spring 4, so that the fixing ring 301 abuts against the first abutting surface 6021. The limiting block 6 plays a limiting role on the spring block 3, thereby limiting the spring block 3 and preventing the spring block 3 from sliding up, so that the workers can easily take off the processed yarn package and insert the new package.

[0024] For further details, please refer to Figure 1 , Figure 2 and Figure 3 As shown, the fixing ring 301 is provided with a through groove 3011 for the limiting block 6 to pass through. The fixing rings 301 on both sides of the through groove 3011 are provided with second guide surfaces 3012. After the cylinder is replaced, when the spring block 3 needs to spring back, the spring block 3 is rotated so that the limiting block 6 is aligned with the through groove 3011. The second guide surface 3012 can guide the limiting block 6 and help the limiting block 6 slide to the through groove 3011. The limiting block 6 will disengage from the spring block 3 through the through groove 3011 and re-abut against the inner support device, thereby greatly reducing the workload of the staff, making the cylinder replacement more convenient, and effectively improving the cylinder replacement efficiency.
