Description

Technical Field

[0001] This utility model relates to the field of spinning, and in particular to a bobbin changing mechanism for a combing machine coiling device. Background Technology

[0002] The main function of a combing machine is to remove shorter fibers and knots (such as neps, wool particles, grass clippings, cocoon skins, etc.) from the fibers, making them straighter and more parallel, ultimately producing combed slivers with a relatively uniform thickness. In the textile industry, combing machines use a series of mechanical and electrical components to finely comb cotton slivers, wool slivers, or synthetic fiber slivers, removing surface impurities and short fibers, making them smoother and more uniform.

[0003] After multiple cotton slivers are combed by the combing machine, they are combined into a single combed sliver. The combined combed sliver is then fed into the coiling mechanism of the combing machine for coiling and feeding, so that the combed sliver is evenly wound into the collecting can. When the collecting can is full of combed sliver, it needs to be removed from the rotating base of the coiling mechanism and replaced with an empty collecting can. However, the rotating base has a certain height, and it takes a lot of physical strength to put on or remove the collecting can, especially when the collecting can is full of combed sliver. Utility Model Content

[0004] The purpose of this invention is to provide a can changing mechanism for the sliver coiling device of a combing machine, which has the advantage of replacing manual replacement of the collection can filled with cotton sliver.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A canister changing mechanism for a combing machine coiling device includes a base with a cavity inside. A motor is fixedly connected to the top of the cavity. The motor output shaft passes through the top surface of the cavity and extends to the outside of the base. A mounting plate is placed on the upper surface of the base, and the motor output shaft is fixedly connected to the mounting plate. A lifting mechanism is provided on the upper part of the mounting plate, and the lifting mechanism is connected to a mounting base. Two columns are rotatably connected to both ends of the mounting base. The lower end of each column passes through the bottom of the mounting base. A transmission mechanism is provided between two connecting arms located at the same end of the mounting base. Each column is connected to a connecting arm, and each connecting arm is fixedly connected to a clamping plate.

[0006] Using the above technical solution, the collecting cylinder is placed between the clamps on two connecting arms located at the same end of the mounting base. The transmission mechanism drives the two connecting arms to rotate, causing the connecting arms to bring the two clamps closer together, clamping the collecting cylinder between them. The lifting mechanism drives the mounting base to rise, which in turn drives the clamps and the collecting cylinder held by the clamps to rise. The motor then drives the mounting base to rotate, which in turn drives the clamps and the collecting cylinder to rotate, bringing the collecting cylinder to the upper part of the rotating base of the coiling device. The lifting mechanism drives the collecting cylinder to descend and place it on the rotating base. The transmission mechanism, through the connecting arms, drives the two clamps to move away from each other, releasing the collecting cylinder. The coiling device then drives the combed slivers into the collecting cylinder. The rotating base drives the collecting cylinder to rotate, ensuring that the combed slivers are evenly placed in the collecting cylinder. When the collecting cylinder is full of combed slivers, the mounting base... An empty cylinder is placed between two clamping plates at the end of the mounting base furthest from the coiling device. The transmission mechanism pushes the two clamping plates to clamp the empty cylinder. At the same time, the transmission mechanism at the other end of the mounting base drives the clamping plate connected to it to clamp the collecting cylinder on the rotating base. The lifting mechanism drives the collecting cylinder and the empty cylinder to rise, separating the collecting cylinder from the bottom surface of the disc base and the empty cylinder from the ground. The motor drives the two empty cylinders to rotate, causing the collecting cylinder to leave the coiling device and the empty cylinder to approach the coiling device. Then, the lifting mechanism drives the two cylinders to rise again, making the bottom surface of the empty cylinder higher than the bottom surface of the rotating base. The mounting base continues to drive the empty cylinder to rotate. The empty cylinder moves to above the rotating base, and the lifting mechanism drives the two cylinders to descend, placing the empty cylinder on the rotating base. The cylinder containing the combed strips is placed on the ground. The cylinders are not manually lifted and placed on or removed from the disc base, saving physical effort.

[0007] Preferably, the transmission mechanism includes a first rotating rod, a second rotating rod, a connecting rod, and a first cylinder. The first rotating rod and the second rotating rod are fixedly connected to the bottom ends of two columns located at the same end of the mounting plate. The first rotating rod is fixedly connected to the bottom end of one column at one end, and the second rotating rod is fixedly connected to the other column between its two ends. A connecting rod is hinged between the first rotating rod and the second rotating rod. The hinge points of the connecting rod and the two rotating rods are located on both sides of the line connecting the lower ends of the two columns. The mechanism also includes a first cylinder. The output shaft end and the bushing of the first cylinder are hinged to the first rotating rod and the second rotating rod, respectively. The hinge point of the first cylinder and the two rotating rods is located on one side of the line connecting the lower ends of the two columns.

[0008] Using the above technical solution, the cylinder's output shaft extends or retracts, driving one of its connected rotating rods to rotate. The rotating rod drives the other rotating rod to rotate in the opposite direction through a connecting rod, thereby causing the two rotating rods to move the two clamping plates closer together or further apart.

[0009] Preferably, the lifting mechanism includes a guide column, a column cylinder, and a second cylinder. There are multiple column cylinders and guide columns. The guide columns are vertically fixedly connected to the upper part of the mounting plate, and the column cylinders are vertically fixedly connected to the bottom of the mounting base. The guide columns are embedded in the column cylinders, and the two are slidably connected. There are multiple second cylinders. The second cylinders are hinged to the upper part of the mounting plate, and the output shaft of the second cylinders is hinged to the column cylinders.

[0010] Using the above technical solution, the output shaft of cylinder 2 extends or retracts, pushing the column cylinder to rise or fall along the guide column. The column cylinder drives the mounting base to rise or fall, the motor drives the base to rotate, and the mounting plate drives the mounting base to rotate through the column cylinder and column sleeve.

[0011] Preferably, the mounting base includes an upper base plate, a lower base plate, and a connecting plate. The connecting plate is located between the upper and lower base plates, and both sides of the connecting plate are fixedly connected to the upper and lower base plates respectively. Both ends of the column are rotatably connected to the upper and lower base plates respectively. The lower end of the column passes through the bottom of the lower base plate, and the column cylinder is fixedly connected to the bottom surface of the lower base plate.

[0012] Preferably, a rubber pad is fixedly connected to the surface of the clamping plate.

[0013] By adopting the above technical solution, the stability between the clamping plate and the collecting cylinder is increased, and slippage between the two is prevented. Attached Figure Description

[0017] See Figures 1 to 5A canister changing mechanism for a combing machine coiling device includes a base 1 with a cavity inside. A motor 2 is fixedly connected to the top of the cavity, and the output shaft of the motor 2 passes through the top surface of the cavity and extends to the outside of the base 1. A mounting plate 3 is placed on the upper surface of the base 1. The output shaft of the motor 2 passes through the bottom of a mounting base 4 and is fixedly connected to the mounting plate 3. Multiple vertical guide posts 12 are fixedly connected to the upper part of the mounting plate 3. The mounting base 4 includes an upper base plate, a lower base plate, and a connecting plate. The connecting plate is located between the upper and lower base plates, and its two sides are fixedly connected to the upper and lower base plates respectively. Multiple vertical cylinders 13 that match the guide posts 12 are fixedly connected to the bottom surface of the lower base plate. The guide posts 12 are embedded in the cylinders 13 and the two are slidably connected. Multiple cylinders 14 are hinged to the upper part of the mounting plate 3, and the output shafts of the cylinders 14 are hinged to the cylinders 13. The mounting base 4 has two uprights rotatably connected to its two ends. The two ends of the uprights 5 are rotatably connected to the upper and lower base plates, respectively. The lower ends of the uprights 5 pass through the bottom of the lower base plate. The bottom ends of the two uprights 5 located at the same end of the mounting plate 3 are respectively fixedly connected to rotating rod 1 8 and rotating rod 2 9. Rotating rod 1 8 is fixedly connected at one end to the bottom end of one upright 5, and rotating rod 2 9 is fixedly connected between its two ends to the other upright 5. A connecting rod 10 is hinged between rotating rod 1 8 and rotating rod 2 9. The hinge points of the connecting rod 10 and the two rotating rods are located on both sides of the line connecting the lower ends of the two uprights 5. The mounting base also includes a cylinder 11. The output shaft end and bushing of cylinder 11 are hinged to rotating rod 1 8 and rotating rod 2 9, respectively. The hinge point of cylinder 11 and the two rotating rods is located on one side of the line connecting the lower ends of the two uprights 5. Each upright 5 is connected to a connecting arm 6, and each connecting arm 6 is fixedly connected to a clamping plate 7.

[0018] Working principle: The collection cylinder is placed between the clamping plates 7 on the two connecting arms 6 located at the same end of the mounting base 4. The output shaft of cylinder 11 extends, driving one of the connecting rods to rotate. The rotating rod drives the other rotating rod to rotate in the opposite direction through the connecting rod 10. Thus, the two rotating rods drive the two connecting arms 6 to move closer together, and the connecting arms 6 drive the two clamping plates 7 to move closer together, clamping the collection cylinder between them. The output shaft of cylinder 2 14 extends, pushing the column cylinder 13 to rise along the guide column 12. The column cylinder 13 drives the mounting base 4 to rise, and the mounting base 4 drives the clamping plates 7 and the collection cylinder clamped by the clamping plates 7 to rise. The motor 2 drives the base 1 to rotate, and the mounting plate 3 drives the mounting base 4 to rotate through the column cylinder 13 and the column sleeve. The mounting base 4 drives the clamping plates 7 and the collection cylinder to rotate. Bring the collecting cylinder to the upper part of the rotating base 1 of the coiling device. The output shaft of cylinder 2 14 retracts, driving the column cylinder 13 to descend along the guide column 12. The column cylinder 13 drives the mounting base 4 to descend and place it on the rotating base 1. The output shaft of cylinder 11 retracts, driving the two clamping plates 7 to move away from each other and releasing the collecting cylinder.

[0019] The coiling device draws the combed slivers into the collecting drum. The rotating base 1 rotates the collecting drum, ensuring the combed slivers are evenly distributed within it. Once the collecting drum is full, an empty drum is placed between two clamping plates 7 at the end of the mounting base 4 furthest from the coiling device. The output shaft of cylinder 11 extends, clamping the clamping plates 7 and holding the collecting drum on the rotating base 1 and the empty drum outside the rotating base 1. The output shaft of cylinder 2 14 extends, lifting the collecting drum and the empty drum, separating the collecting drum from the bottom surface of the disc base 1 and the empty drum from the ground. Motor 2 rotates the two drums, moving the collecting drum away from the coiling device and the empty drum closer to it. A lifting mechanism then lifts the two drums again, raising the bottom surface of the empty drum above the bottom surface of the rotating base 1. The mounting base 4 continues to rotate the empty drum, moving it above the rotating base 1. The lifting mechanism then lowers the two drums, placing the empty drum on the rotating base 1 and the drum containing the combed slivers on the ground. This eliminates the need for manual lifting of the collecting drum to place or remove it from the disc base 1, reducing strain and saving labor.
