Description

Technical Field

[0001] This invention relates to the field of yarn tube mounting bracket technology, and in particular to an adjustable length yarn tube mounting bracket for spinning machines. Background Technology

[0002] A spinning frame is a spinning machine that turns semi-finished roving into fine yarn through a series of processes during the spinning process. The spinning frame is the main machine for spinning. When spinning, the spinning frame uses yarn bobbins. When the yarn bobbins are used, they need to be mounted on the spinning frame through a mounting frame. The automatic loading and unloading of yarn bobbins on the mounting frame can be achieved through a flipping feeding mechanism.

[0003] For example, application number CN201921503486.5 relates to an installation structure for a collective doffing and tube-handling device for a spinning frame, comprising a spinning frame, which includes a headstock, a body, and a tailstock connected sequentially from front to back. The device is characterized in that a tube-handling device is provided on the front side of the headstock, the device includes a tube-handling compartment, a tube-handling mechanism is provided inside the compartment, a tube storage box is provided on the feed side of the compartment, and an inclined tilting feeding mechanism is provided on one side of the compartment. This utility model's installation structure for a collective doffing and tube-handling device for a spinning frame has the advantages of making reasonable use of space and facilitating later maintenance.

[0004] However, there are still some shortcomings in the current design of the yarn tube mounting bracket for spinning machines. First, the existing yarn tubes are inserted into the spindles. During operation, the spindles drive the yarn tubes to rotate at high speed. Due to the lack of a stable structure at the top of the yarn tube, the yarn tubes will move up and down during rotation, thus affecting the normal use of the yarn tubes. If a stable structure is installed at the top of the yarn tubes, it will affect the flipping feeding mechanism for changing the yarn tubes. Second, since the yarn tubes are inserted into the spindles of the mounting bracket, frequent insertion and removal of the yarn tubes can easily cause internal friction, resulting in gaps in the mounting part of the yarn tubes after assembly, leading to loosening of the installation and affecting the use of the yarn tubes. Summary of the Invention

[0005] To address the above problems, this invention proposes an adjustable-length yarn tube mounting bracket for spinning machines, which increases the stability of the yarn tube during use, does not affect the yarn tube replacement by the flipping feeding mechanism, and uses a movable rod to fix the yarn tube, preventing the yarn tube from becoming loose due to long-term friction.

[0016] This invention provides an adjustable length yarn tube mounting bracket for a spinning machine, which has the following advantages:

[0017] 1. This invention incorporates a sliding mechanism and a transmission mechanism. A lifting component is slidably mounted inside the base, with a round rod-shaped structure on the lifting component extending from the top of the base. A transmission wheel is rotatably mounted at the bottom of the base, and a movable rod is slidably mounted inside the transmission wheel. Two sets of movable rods are connected by a small gear. The movable rod passes through the lifting component of the base, and a rectangular block on the movable rod extends from the upper end of the base. A connecting ring is inserted at the bottom of the yarn tube. In use, the yarn tube is moved to the upper end of the base by a flipping feeding mechanism, and the yarn tube falls onto the round rod on the lifting component. By pressing the yarn tube, the lifting component can be pushed to the lower end of the base. As the lifting component moves, the side block is pushed to bring the two sets of movable rods together towards the middle of the transmission wheel. The rectangular blocks at the top of the two sets of movable rods after retraction can be inserted into the rectangular grooves in the connecting ring. When the lifting component slides to the lower end of the side block, the spring pushes the movable rod to both sides, and the rectangular block is locked in the rectangular groove in the connecting ring. This prevents the yarn tube from moving up and down as it rotates with the movable rod.

[0018] 2. This invention incorporates a lifting mechanism. A lifting rod is slidably mounted on the transmission box, and a top rod is installed on the lifting rod. A rotating component is rotatably mounted on the front side of the top rod. When the yarn tube falls onto the base, the flip-feeding mechanism falls, causing the base to return to its forward position. Simultaneously, as the base moves forward, the lifting rod is driven to fall via the transmission gear, causing the rotating component to engage with the replaced yarn tube. This improves the stability of the yarn tube during rotation. Furthermore, during feeding, the top rod is raised, thus not affecting the replacement of the yarn tube.

[0019] 3. This invention incorporates a sliding mechanism and a transmission mechanism. A trigger plate is installed at the bottom of the base, allowing it to slide against the base via a side rod. The movable rod extends from the bottom of the transmission wheel and contacts the arc-shaped groove inside the trigger plate. When the flipping feeding mechanism flips up and unloads the material, it pushes the trigger plate backward. As the trigger plate moves backward, the arc-shaped groove causes the two sets of movable rods to move closer to the center of the transmission wheel. At this point, the wedge-shaped block on the movable rod loses its limiting effect on the connecting ring, and the lifting component lifts the yarn tube, thereby assisting the flipping feeding mechanism in changing the tube.

[0020] 4. This invention incorporates a lifting mechanism with equidistant circular positioning holes at the upper end of the lifting rod and positioning pins at the rear end of the top rod. When installing the yarn tube, the top rod can be adjusted to the position on the lifting rod according to the length of the yarn tube, allowing the positioning pins to be inserted into the corresponding positioning holes, thereby fixing the top rod on the lifting rod. This provides stability when using yarn tubes of different lengths. Attached Figure Description

[0063] The specific usage and function of this embodiment are as follows:

[0064] In this invention, such as Figures 1 to 11As shown, the transmission box 101 is fixed to the fixed plate 102, and then the fixed plate 102 is fixed to the spinning machine. The toothed plate 2041 is inserted into the rear groove 204 on the rear side of the base 201 and then fixed with bolts. A support rod 1021 is set on the front side of the fixed plate 102. The front end of the support rod 1021 is fixed to the bottom of the base 201, so that the toothed plate 2041 on the rear side of the base 201 extends into the transmission box 101 and the toothed plate 2041 is connected to the transmission gear 1011. The top rod 401 is sleeved onto the lifting rod 4. At the top of 02, insert the positioning bolt 4012 on the top rod 401 into the positioning hole 4021 of the lifting rod 402. When the flipping feeding mechanism is feeding, the feeding frame flips upward and pushes the base 201 backward. As the base 201 moves backward, the top rod 401 is lifted upward by the transmission gear 1011.

At this point, by rotating the transmission wheel 301, the transmission wheel 301 can drive the yarn tube 501 to rotate via the movable rod 302, and... When the yarn tube 501 needs to be replaced during textile work, the feeding frame flips up again and pushes the base 201 backward. As the base 201 moves backward, the rotating part 4011 disengages from the upper end of the yarn tube 501. When the feeding frame flips, it pushes the trigger plate 203 backward, which in turn pushes the movable rod 302 to the middle position of the transmission wheel 301 to close together. At this time, the lifting part 202 pushes the yarn tube 501 up, so that the feeding frame can replace the yarn tube 501.
