Description

Technical Field

[0001] This utility model relates to the field of yarn technology, specifically to an automatic doffing device. Background Technology

[0002] The textile industry is an essential part of people's daily lives. Yarn, as one of the raw materials in the textile industry, is generally produced by winding yarn onto a spool. The spool is usually installed on a doffing machine to wind the yarn. After the existing doffing machine finishes winding the yarn, manual doffing is required. When doffing manually, the yarn spools need to be removed from the doffing machine one by one and transported to the storage room. This doffing efficiency is low and cannot meet the needs of users. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic doffing device that can quickly doff yarn from a yarn roll, thereby improving production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An automatic doffing device includes a flipping module, a winding module, and a doffing conveyor module. The doffing conveyor module is disposed on one side of the flipping module, and the winding module is mounted on the flipping module.

[0006] The flipping module includes a mounting base, a flipping motor, a flipping shaft, and a connecting frame. The mounting base is fixedly installed on the ground. The top of the mounting base has several mounting slots that are adapted to the connecting frame. The connecting frame is installed in the mounting slots. A flipping shaft is provided at the mounting base. The flipping shaft passes through each mounting slot and is fixedly connected to the connecting frame. The end of the flipping shaft is fixedly connected to the output shaft of the flipping motor. The flipping motor is fixedly installed at the mounting base.

[0007] The yarn winding module includes a mounting plate, several rotary motors, a transmission mechanism, and several mounting shafts.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 2 The present invention provides the following technical solution:

[0021] An automatic doffing device includes a flipping module, a winding module, and a doffing conveying module. The winding module is mounted on the flipping module and is used to flip the winding module. The winding module is used to mount a yarn winding spool to wind the yarn. The doffing conveying module is located on one side of the flipping module so that after the flipping module flips the winding module, the yarn spool can fall onto the doffing conveying module.

[0022] The flipping module includes a mounting base 4, a flipping motor 6, a flipping shaft 7, and a connecting frame 8. The mounting base 4 is fixedly installed on the ground. The top of the mounting base 4 has several mounting slots 5, which are adapted to the connecting frame 8. The connecting frame 8 is installed in the mounting slots 5. The mounting base 4 is used to install the connecting frame 8. The mounting base 4 is provided with a flipping shaft 7, which passes through each mounting slot 5 and is fixedly connected to the connecting frame 8. The flipping shaft 7 enables the connecting frame 8 to be stably installed on the mounting base 4. The end of the flipping shaft 7 is fixedly connected to the output shaft of the flipping motor 6. The flipping motor 6 is fixedly installed on the mounting base 4 and is used to drive the flipping shaft 7 to rotate, thereby causing the flipping shaft 7 to drive the connecting frame 8 to move together.

[0023] The yarn winding module includes a mounting plate 10, several rotary motors 11, a transmission mechanism 12, and several mounting shafts 13. The mounting plate 10 is fixedly mounted at the end of the mounting frame, so that the connecting frame 8 can drive the mounting plate 10 to move together. The mounting shafts 13 are rotatably mounted on the mounting plate 10 through bearings. The mounting shafts 13 are used to mount the winding bobbins. The bottom end of the mounting shaft 13 passes through the mounting plate 10, and the ends of each mounting shaft 13 that pass through the mounting plate 10 are connected to each other through the transmission mechanism 12. Several rotary motors 11 are mounted on the mounting plate 10. The output shafts of the rotary motors 11 are connected to the mounting shafts 13 through the transmission mechanism 12. The rotary motors 11 can drive each mounting shaft 13 to rotate through the transmission mechanism 12, thereby causing the winding bobbins on the mounting shafts 13 to rotate and wind the yarn.

[0024] Mounting shaft 13 is an air-expanding shaft. When the air-expanding shaft expands, the winding drum can be stably mounted on mounting shaft 13.

[0025] A support plate 9 is fixedly installed on the side of the mounting base 4 away from the material feeding conveyor module. The support plate 9 abuts against the connecting frame 8. The support plate 9 is used to support the connecting frame 8 and limit the position of the connecting frame 8.

[0026] A limit block 14 is provided on the side of the mounting slot 5 near the unloading conveyor module. The limit block 14 limits the rotation angle of the connecting frame 8 to prevent the connecting frame 8 and the yarn winding module from swinging excessively.

[0027] The transmission mechanism 12 is a chain and sprocket transmission mechanism, which can reliably drive each mounting shaft 13 to rotate.

[0028] The material feeding and conveying module includes a conveyor belt 1 and a baffle 2. The baffle 2 is installed on the side of the conveyor belt 1 away from the flipping module. The baffle 2 can prevent the yarn roll from falling off the conveyor belt 1 when it falls onto the conveyor belt 1.

[0029] An inclined guide plate 3 is installed on the side of the mounting base 4 near the conveyor belt 1. The guide plate 3 is used to guide the yarn roll to fall onto the conveyor belt 1.

[0030] The specific implementation process is as follows:

[0031] When using this automatic doffing device, first install the winding bobbin on the mounting shaft 13, then start the mounting shaft 13 to expand it, thus firmly installing the winding bobbin on the mounting shaft 13. Then start the rotary motor 11, which drives each mounting shaft 13 to rotate through the transmission mechanism 12. The mounting shaft 13 can then rotate to wind up the yarn. After the yarn is wound up, the flip motor 6 starts, which drives the flip shaft 7 to rotate. The flip shaft 7 drives the winding module to flip through the connecting frame 8. After the winding module is flipped into place, the mounting shaft 13 retracts, so that the yarn can fall onto the guide plate 3 under the action of gravity. Through the guiding effect of the guide plate 3 and the blocking effect of the baffle 2, the yarn falls onto the conveyor belt 1 and is transported by the conveyor belt 1. Then the flip module resets.

[0032] This automatic doffing device uses a winding module to install a winding drum, which rotates to wind the yarn onto the drum. A flipping module causes the winding module and the yarn roll on it to flip, allowing the yarn roll to detach from the winding module under the influence of gravity and fall onto conveyor belt 1 for transport. This device can effectively improve the doffing efficiency of yarn, thereby increasing the production efficiency of yarn.
