Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a bobbin installation and detachment structure for a spinning spindle in a textile machinery component. Background Technology

[0002] The spinning spindle is an important component of textile machinery. Yarn is wound around a bobbin to form a yarn tube. The yarn tube is installed on the spindle to feed yarn to the weaving mechanism. After the yarn is used up, the bobbin is removed from the spindle and a new yarn tube is installed. Therefore, the spindle rod and the bobbin need to have a device and structure that facilitates the installation and removal of the bobbin. At the same time, the bobbin must be prevented from rotating on the spindle rod and be coaxial with the spindle rod.

[0003] A bobbin is an I-beam-shaped device that facilitates yarn storage and is fitted onto a spindle. Existing structures that satisfy the above-mentioned assembly relationship between the bobbin and the spindle have two conical openings at both ends of the bobbin mounting hole, with the larger opening facing outwards. A lower support and an upper pressure member are provided between the spindle and the bobbin, both fitted onto the spindle. The lower support has an inner and outer conical surface, and the upper pressure member has an outer conical surface. The outer conical surfaces of the upper and lower pressure members are aligned and fit into the conical openings at both ends of the bobbin. The inner conical surface of the lower support, with its larger opening facing downwards, fits onto the conical platform of the spindle and is axially supported by the spindle. The lower support and upper pressure member achieve anti-rotation and centering of the bobbin on the spindle. The upper pressure member also... The device includes a movable part and a positioning part above the movable part. The outer conical surface of the upper pressure part is located on the movable part. The positioning part has a pin that springs upward along the spindle. The spindle has a pin groove or pin hole. The pin of the positioning part is pressed out of the pin hole and released into the pin hole. This can realize the axial positioning and retraction of the positioning part sleeved on the spindle. A spring is also sleeved on the spindle between the positioning part and the movable part. The spring forms a spring force on the movable part, causing the movable part to press on the tube. This radial pin structure of the positioning part causes the rotating part to be unbalanced, resulting in obvious vibration. Even with a balance block, the vibration at high speed cannot be overcome. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a bobbin installation and removal structure for spinning spindles, which overcomes the problems of imbalance and significant vibration of the rotating parts in the existing bobbin installation and removal structures.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a bobbin installation and detachment structure for a spinning spindle, wherein the bobbin is installed on the spindle rod via a lower support and an upper pressure member that are both sleeved on the spindle rod. The bobbin has a lower conical opening and an upper conical opening. The lower support has an inner conical surface that mates with a frustum on the spindle rod and a first outer conical surface that mates with the lower conical opening of the bobbin. The upper pressure member has a second outer conical surface that presses against the upper conical opening of the bobbin. The upper pressure member applies pressure to the bobbin, thereby axially positioning and circumferentially preventing rotation of the bobbin and fixing it to the spindle rod. The upper pressure member is detachably sleeved on the spindle rod. The structure on the spindle is as follows: the upper pressing member includes a movable member, a strong spring, and a positioning member arranged from bottom to top. The second outer conical surface of the upper pressing member is located on the movable member. The positioning member includes a lock seat and a spring-loaded cover. The strong spring is sleeved on the spindle and its two ends abut against the movable member and the lock seat, respectively. The outer ring of the spindle is provided with an annular locking groove. The lock seat has movable locking rods evenly distributed around the circumference of the spindle. The locking tongue on the locking rod, which is close to the axis of the spindle, can enter the locking groove and restrict the upward movement of the lock seat when entering. The lock seat is provided with a reset locking spring that pushes the locking rod to keep the locking tongue in the locking groove or tends to enter the locking groove. The lock seat, which is restricted from moving upward, pushes the strong spring to create pressure on the bobbin, so that the bobbin is fixedly installed on the spindle. When the spring cover is pressed down, the lock rod is driven to disengage the lock tongue from the lock groove, and the strong spring pushes the lock seat upward to remove the bobbin from the spindle.

[0006] Specifically, the locking rod is oscillating on the lock seat, and the oscillation surface of the locking rod is parallel to the axis of the spindle. The locking rod has an inner section that is close to the axis of the spindle and an outer section that is far from the axis of the spindle, which are divided by the oscillation fulcrum. The structure of the spring cover driving the locking rod to make the lock tongue exit the lock groove is that the outer section of the locking rod has a sloping surface. When the spring cover moves down, the outer ring of the spring cover presses against the sloping surface to drive the locking rod to oscillate.

[0007] Specifically, the locking rods are three rods that are evenly distributed around the circumference of the lock base.

[0008] Specifically, the reset locking spring also has a first anti-disengagement hook that hooks onto the spring cover, which prevents the spring cover from detaching from the lock seat.

[0009] Specifically, the movable part has at least two second anti-disengagement hooks distributed circumferentially on the lock seat, which prevent the lock seat from detaching from the movable part.

[0010] Specifically, the second anti-detachment hook consists of three hooks evenly distributed around the circumference of the moving part.

[0011] Specifically, a top spring is provided between the lock seat and the spring cover to push the spring cover upward and reset it.

[0012] The beneficial effects of this utility model are as follows: The bobbin installation and disassembly structure of this utility model uses a circumferentially arranged locking rod and a circumferential locking groove on the spindle rod. Pressing the spring cover causes the locking tongue to exit the locking groove to achieve bobbin disassembly, and pressing the locking seat causes the locking tongue to enter the locking groove to achieve bobbin installation. The shape of each part has a structure that is evenly arranged circumferentially around the axis of the spindle rod. The rotation of each rotating part is balanced, without forming obvious vibration, with low noise, less damage to the bearings, and a long service life of the spindle. Attached Figure Description

[0016] The present invention will now be further described with reference to the accompanying drawings, which are simplified schematic diagrams illustrating only the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0017] As attached Figure 1 A bobbin installation and detachment structure for a spinning spindle is disclosed. The bobbin 1 is installed on the spindle rod 2 via a lower support 3 and an upper pressure member, both of which are fitted onto the spindle rod 2. The bobbin 1 has a lower conical opening 1-1 and an upper conical opening 1-2. The lower support 3 has an inner conical surface that mates with the frustum 2-1 on the spindle rod 2 and a first outer conical surface that mates with the lower conical opening 1-1 of the bobbin 1. The upper pressure member has a second outer conical surface 4-1 that presses against the upper conical opening 1-2 of the bobbin 1. Pressure is applied to the bobbin 1 by the upper pressure member, causing the bobbin 1 to be axially positioned and circumferentially fixed to the spindle rod 2 to prevent rotation. The fixing of the bobbin 1 utilizes the mechanical principle of conical surface mating to prevent rotation. The upper pressing component is detachably fitted onto the spindle rod 2. The upper pressing component comprises a movable component 4, a strong spring 5, and a positioning component 6 arranged from bottom to top. These three components are not in an absolute vertical relationship; adjacent components have interlocking parts. The second outer conical surface 4-1 of the upper pressing component is located on the movable component 4. The positioning component 6 includes a locking seat 6-1 and a spring-loaded cover 6-2. The strong spring 5 is fitted onto the spindle rod 2, with its two ends pressing against the movable component 4 and the locking seat 6-1 respectively. An annular locking groove 2-2 is provided on the outer ring of the spindle rod 2. Movable locking rods 6-3 are evenly distributed around the circumference of the spindle rod 2 on the locking seat 6-1. (The last sentence appears to be incomplete and possibly refers to a different component.) Figure 4 and attached Figure 5 The diagram of the lock seat illustrates the distribution of the locking rods 6-3. The locking rods 6-3 are three rods that are evenly distributed around the circumference of the lock seat 6-1. The locking rods 6-3 are oscillating on the lock seat 6-1. The oscillation surface of the locking rods 6-3 is parallel to the axis of the spindle 2. The locking rods 6-3 have an inner section that is close to the axis of the spindle 2 and an outer section that is far from the axis of the spindle 2, which are divided by the oscillation fulcrum.

[0018] The locking tongue 6-3-1 on the locking rod 6-3, which is close to the axis of the spindle 2, can enter the locking groove 2-2 and restrict the upward movement of the locking seat 6-1 during entry, as shown in the attached figure. Figure 1 This refers to the state where the bolt 6-3-1 is located in the lock groove 2-2. The annular lock groove 2-2 has a rectangular groove shape and an upper end face that serves as the locking surface. The upper surface of the bolt 6-3-1 rests on this upper end face. The lock seat 6-1 is provided with a return locking spring 6-4 that pushes the locking rod 6-3 to keep the bolt 6-3-1 in the lock groove 2-2 or to make it tend to enter the lock groove 2-2. The shape of the return locking spring 6-4 is shown in the attached figure. Figure 8 and attached Figure 9 The inner ring of the reset locking spring 6-4 has an elastic arm that presses against the outer section of the locking rod 6-3. The direction of the force exerted by the elastic arm on the outer section of the locking rod 6-3 is opposite to the direction of the driving force exerted by the spring cover 6-2 on the locking rod 6-3 as described below. From the appendix Figure 1 As can be seen above, the lock seat 6-1, which is restricted from moving upward, pushes the strong spring 5 to exert pressure on the movable part 4, so that the tube 1 is fixedly installed on the spindle 2; when the spring cover 6-2 is pressed down, it drives the locking rod 6-3 to make the locking tongue 6-3-1 exit the locking groove 2-2, and the strong spring 5 pushes the lock seat 6-1 to move upward, so that the tube 1 can be detached from the spindle 2; when the spring cover 6-2 is pressed, because the strong spring 5 has a large elastic force, it will not be compressed, but will instead push the lock seat 6-1 to move upward when the locking tongue 6-3-1 exits, and the structure of the spring cover 6-2 driving the locking rod 6-3 to make the locking tongue 6-3-1 exit the locking groove 2-2 is that the outer section of the locking rod 6-3 has a slope surface 6-3-2. When the spring cover 6-2 moves down, the outer ring of the spring cover 6-2 presses against the slope surface 6-3-2 to drive the locking rod 6-3 to swing.

[0019] The following section will explain some of the structural details.

[0020] The reset locking spring 6-4 also has a first anti-disengagement hook 6-4-1 that hooks onto the spring cover 6-2, from the attached Figure 1 Assembly relationship diagram, attachment Figure 8 and attached Figure 9 Schematic diagram and appendix of the reset locking spring 6-4 Figure 6 and attached Figure 7 The schematic diagram of the spring-loaded cover 6-2 shows that the first anti-disengagement hook 6-4-1 prevents the spring-loaded cover 6-2 from detaching from the lock seat 6-1. The hook part of the first anti-disengagement hook 6-4-1 is located in the inner wall groove that is sealed at the lower end of the spring-loaded cover 6-2.

[0021] As attached Figure 2 and attached Figure 3 As shown, three second anti-disengagement hooks 4-2 are evenly distributed around the circumference of the movable part 4, which hook onto the lock seat 6-1. The second anti-disengagement hooks 4-2 prevent the lock seat 6-1 from detaching from the movable part 4. Figure 4 and attached Figure 5 The lock base 6-1 has three holes evenly distributed around its circumference, allowing the second anti-disengagement hook 4-2 to pass through after elastic deformation.

[0022] See appendix Figure 1 A top spring 6-5 is provided between the lock seat 6-1 and the spring cover 6-2 to push the spring cover 6-2 back to its original position. The shape of the top spring 6-5 is shown in the attached figure. Figure 10 and attached Figure 11 The top spring 6-5 has a downward folding part that abuts against the top surface of the support column on the lock seat 6-1 that provides swing support for the lock rod 6-3.
