Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to a rotating frame for a coiling device. Background Technology

[0002] After cotton lint is processed into slivers by the drawing machine, it is evenly wound into sliver cans by the coiling mechanism. When the sliver can is full, the worker takes the can with slivers out of the coiling device and replaces it with an empty can. Since it takes some time to refill the sliver can with a certain amount of slivers, the worker will do other work during the coiling process. It is quite troublesome to come back and replace the can after it is full.

[0003] Therefore, a changing frame is usually set up at the coiling mechanism. Multiple tampons are placed in the changing frame. The changing frame carries one of the tampons into the coiling device to collect the tampons. When the tampon is full, the changing frame takes the tampon out of the coiling device and puts the empty tampon into the coiling device. Once all the tampons on the changing frame are full, the worker returns to change them, reducing the frequency of the worker's back and forth and saving physical strength.

[0004] A typical tampon holder includes a rotating column with multiple mounting arms. Limiting rods are installed on both sides of each mounting arm. The tampon can is positioned between two mounting arms, and the limiting rods prevent it from detaching from the holder. The rotating column drives the mounting arms to rotate, pushing the tampon can into or out of the coiling device. However, when inserting or removing the tampon can from between the mounting arms, one of the limiting rods must be removed so that the tampon can pass between the two mounting arms. After that, the limiting rod must be reinstalled, making the operation cumbersome. Utility Model Content

[0005] The purpose of this invention is to provide a rotating frame for a coiling device, which has the advantage of facilitating the placement of cotton sliver tubes in the coiling mechanism's changing frame.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A rotating frame for a coiling device includes a base, a connecting column rotatably connected to the base, and mounting arms fixedly connected to the outer wall of the connecting column. A placement area is formed between two adjacent mounting arms. Each mounting arm is connected to a first limiting rod and a second limiting rod. The ends of the first and second limiting rods on the same mounting arm face opposite sides of the mounting arm. A vertical stop bar passes through the end of the second limiting rod. The first limiting rod is hinged to the mounting arm. A rotating shaft is fixedly connected to the end of the first limiting rod connected to the mounting arm. The rotating shaft is rotatably connected to the mounting arm and fixedly connected to an internal spline. The device also includes a cylindrical cam cylinder. The inner wall of the cylindrical cam cylinder has a spline groove matching the internal spline, which is embedded in the cylindrical cam cylinder and slidably connected to it. A protruding post is fixedly connected to the mounting arm and embedded in the groove of the cylindrical cam cylinder. A driving mechanism is fixedly connected to the mounting arm, and the cylindrical cam cylinder is connected to the driving mechanism.

[0008] Using the above technical solution, the drive mechanism drives the cylindrical cam cylinder to move. The cylindrical cam cylinder slides relative to the internal spline. The convex column exerts a force on the side wall of the groove of the cylindrical cam cylinder, causing the cylindrical cam cylinder to rotate while moving. The rotating cylindrical cam cylinder drives the rotating shaft and the first limiting rod to rotate through the spline, moving it away from the second limiting rod on the other mounting arm adjacent to its mounting arm. Thus, the cotton swab can be placed between the two adjacent mounting arms without the need to disassemble or assemble the limiting rod, which is more convenient.

[0009] Preferably, the driving mechanism is a cylinder, which is fixedly connected to the mounting arm. A connecting block is fixedly connected to the cylinder output shaft, the connecting block is slidably connected to the mounting arm, and the cylindrical cam cylinder is rotatably connected to the connecting block.

[0010] Using the above technical solution, the cylinder output shaft extends to push the connecting block to move, the connecting block drives the cylindrical cam cylinder to move, and the cylindrical cam cylinder rotates relative to the connecting block under the action of the convex column.

[0011] Preferably, a protective cover is fixedly connected to the mounting arm, and the cylinder, cylindrical cam cylinder and internal spline are located inside the protective cover.

[0012] The above technical solution is adopted to prevent external damage to the cylinder, cylindrical cam cylinder and internal spline.

[0013] Preferably, one end of the limiting rod and both ends of the stop rod are rotatably connected to rollers.

[0014] The above technical solution reduces the friction between the limiting rod and the cotton sliver tube. Attached Figure Description

[0022] See Figures 1 to 5 A rotating frame for a coiling device includes a base 1, a connecting column 2 rotatably connected to the base 1, and mounting arms 3 fixedly connected to the outer wall of the connecting column 2. A placement area is formed between two adjacent mounting arms 3. Each mounting arm 3 is connected to a first limiting rod 4 and a second limiting rod 5. The ends of the first limiting rod 4 and the second limiting rod 5 on the same mounting arm 3 face opposite sides of the mounting arm 3. The first limiting rod 4 and the second limiting rod 5 on two adjacent mounting arms 3 are opposite each other. A vertical stop bar passes through the end of the second limiting rod 5. Rollers 14 are rotatably connected to the end of the first limiting rod 4 and both ends of the stop bar. The first limiting rod 4 is hinged to the mounting arm 3. A rotating shaft 6 is fixedly connected to one end of the first limiting rod 4 connected to the mounting arm 3. The rotating shaft 6 is rotatably connected to the mounting arm 3 and has an internal spline 7 fixedly connected to it. A cylinder 11 is fixedly connected to the mounting arm 3. A connecting block 12 is fixedly connected to the output shaft of the cylinder 11. The connecting block 12 is slidably connected to the mounting arm 3. A cylindrical cam cylinder 8 is rotatably connected to the connecting block 12. A spline groove 9 matching the inner spline 7 is opened on the inner wall of the cylindrical cam cylinder 8. The inner spline 7 is embedded in the cylindrical cam cylinder 8, and the two are slidably connected. A protruding post 10 is fixedly connected to the mounting arm 3. The protruding post 10 is embedded in the groove of the cylindrical cam cylinder 8. A protective cover 13 is fixedly connected to the mounting arm 3. The cylinder 11, the cylindrical cam cylinder 8, and the inner spline 7 are located inside the protective cover 13.

[0023] Working principle: The output shaft of cylinder 11 extends and pushes the connecting block 12 to move. The connecting block 12 drives the cylindrical cam cylinder 8 to slide relative to the inner spline 7. The protruding post 10 exerts a force on the groove sidewall of the cylindrical cam cylinder 8, causing the cylindrical cam cylinder 8 to rotate relative to the connecting block 12 while moving. The rotating cylindrical cam cylinder 8 drives the rotating shaft 6 and the limiting rod 4 to rotate through the spline, moving it away from the limiting rod 5 on the other mounting arm 3 adjacent to its own mounting arm 3. This allows the cotton swab can to be placed between the two adjacent mounting arms 3. There is no need to disassemble or reassemble the limiting rod, making it more convenient.
