[0002] In the textile industry, a yarn unwinding machine is a device used to transfer yarn from one type of bobbin to another, playing an important role in the yarn processing process.

[0003] However, in the existing technology, the loading and unloading of traditional yarn bobbins mostly rely on manual operation. They are manually installed onto the rotating shaft of the bobbin loosening machine. After the bobbin is loosened, it is necessary to manually remove the yarn bobbin from the rotating shaft and move it to the designated position. The operation is cumbersome and time-consuming, which seriously affects the working efficiency of the bobbin loosening machine. Especially in large-scale production, frequent loading and unloading of yarn bobbins affects production efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the loading and unloading of traditional yarn bobbins in the existing technology mostly relies on manual operation, which is cumbersome and time-consuming, seriously affecting the working efficiency of the bobbin loosening machine. In particular, in large-scale production, frequent loading and unloading of yarn bobbins affects production efficiency. Therefore, a quick loading and unloading device for yarn bobbins of the bobbin loosening machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick loading and unloading device for yarn bobbins of a yarn loosening machine, comprising a cylinder, one end of the cylinder's telescopic rod being rotatably connected to a drive shaft, the end of the drive shaft being provided with a clamping mechanism, one end of the clamping mechanism being fixedly connected to an end cap, a push rod being penetratingly connected to the center of the outer wall of the end cap, one end of the push rod being fixedly connected to one end of the drive shaft, the other end of the push rod being fixedly connected to a push block, the push block being movably connected to the inner wall of the clamping mechanism, a telescopic groove being penetratingly opened on the outer wall of the clamping mechanism, a top pressing block being rotatably connected to the inner wall of the telescopic groove, and three telescopic grooves being provided, the three telescopic grooves being circumferentially arrayed on the outer wall of the clamping mechanism.

[0006] Preferably, a limiting plate is fixedly sleeved on the outer wall of the clamping mechanism, and a movable groove is provided on one side of the limiting plate.

[0007] Preferably, a rotating rod is provided inside the movable groove, and a connecting shaft is connected through the outer wall of the middle part of the rotating rod, and the connecting shaft is rotatably connected to the inner wall of the movable groove.

[0008] Preferably, a limit clamp is fixedly connected to the outer wall of one end of the rotating rod, and a pressure plate is fixedly connected to the outer wall of the other end of the rotating rod.

[0009] Preferably, a fixed groove is provided on the bottom surface of the inner wall of the movable groove, and a spring is fixedly connected to the inner wall of the fixed groove. The top end of the spring is fixedly connected to the bottom surface of the rotating rod.

[0010] Preferably, a shrinkage groove is provided on the outer wall of one end of the push block, and a spring is provided on the inner wall of the shrinkage groove.

[0011] Preferably, one end of the second spring is fixedly connected to the inner wall of the clamping mechanism.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the pusher is pushed forward by the cylinder-controlled pusher, and its edge is used to squeeze the top pressure block to push it out of the telescopic groove, thereby squeezing and fixing the yarn bobbin outside the clamping mechanism. After the yarn bobbin is wound, the pusher is pulled by the cylinder to retract the top pressure block into the telescopic groove, thereby quickly releasing the yarn bobbin. This makes it easy for users to quickly load and unload the yarn bobbin, greatly shortening the loading and unloading time of the yarn bobbin, reducing the tedious steps of manual operation, and thus improving the overall production efficiency of the yarn bobbin loosening machine.

[0014] 2. In this utility model, by sleeve the yarn bobbin outside the clamping mechanism, the pressure plate is pressed when the yarn bobbin is sleeved outside the clamping mechanism, thereby causing the limiting clamping plate to be lifted at the end of the clamping mechanism. Then, the limiting clamping plate is used to limit the yarn bobbin at the end of the clamping mechanism, thereby preventing the yarn bobbin on the clamping mechanism from falling off and displacing during rotation, and improving the winding stability.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a quick loading and unloading device for yarn bobbins of a yarn loosening machine, including a cylinder 1. One end of the telescopic rod of the cylinder 1 is rotatably connected to a transmission shaft 3. A clamping mechanism 2 is provided at the end of the transmission shaft 3. One end of the clamping mechanism 2 is fixedly connected to an end cap 27. A push rod 26 is passed through the center of the outer wall of the end cap 27. One end of the push rod 26 is fixedly connected to one end of the transmission shaft 3. The other end of the push rod 26 is fixedly connected to a push block 28. The push block 28 is movably connected to the inner wall of the clamping mechanism 2. A telescopic groove 24 is opened through the outer wall of the clamping mechanism 2. A top pressing block 25 is rotatably connected to the inner wall of the telescopic groove 24. Three telescopic grooves 24 are provided, and the three telescopic grooves 24 are distributed in a circumferential array on the outer wall of the clamping mechanism 2.

[0022] The specific settings and functions of this embodiment are described below. By placing the yarn bobbin outside the clamping mechanism 2, the cylinder 1 controls the push rod 26 to push the push block 28, and the edge of the push block 28 presses the top pressure block 25 to push it out of the telescopic groove 24, thereby squeezing and fixing the yarn bobbin outside the clamping mechanism 2. After the yarn bobbin is wound, the cylinder 1 controls the push block 28 to pull the top pressure block 25 back into the telescopic groove 24, thereby quickly releasing the yarn bobbin. This makes it easy for users to quickly load and unload the yarn bobbin, greatly shortening the loading and unloading time of the yarn bobbin, reducing the tedious steps of manual operation, and thus improving the overall production efficiency of the yarn bobbin loosening machine.

[0023] Example 2: Figure 1 - Figure 3 As shown, a limiting plate 21 is fixedly sleeved on the outer wall of the clamping mechanism 2. A movable groove 22 is provided on one side of the limiting plate 21. A rotating rod 23 is provided inside the movable groove 22. A connecting shaft 231 is connected through the middle outer wall of the rotating rod 23. The connecting shaft 231 is rotatably connected to the inner wall of the movable groove 22. A limiting clamp 232 is fixedly connected to the outer wall of one end of the rotating rod 23. A pressure plate 233 is fixedly connected to the outer wall of the other end of the rotating rod 23. A fixing groove 221 is opened on the bottom surface of the inner wall of the movable groove 22. A spring 222 is fixedly connected to the inner wall of the fixing groove 221. The top end of the spring 222 is fixedly connected to the bottom surface of the rotating rod 23. A shrinkage groove 281 is opened on the outer wall of one end of the push block 28. A spring 282 is provided on the inner wall of the shrinkage groove 281. One end of the spring 282 is fixedly connected to the inner wall of the clamping mechanism 2.

[0024] The overall effect of this embodiment is that by placing the yarn bobbin outside the clamping mechanism 2 and using the limiting plate 21 for positioning and blocking, the pressure plate 233 is pressed when the yarn bobbin is placed outside the clamping mechanism 2, thereby causing the limiting clamp 232 to rise at the end of the clamping mechanism 2. The limiting clamp 232 then limits the yarn bobbin at the end of the clamping mechanism 2, thereby preventing the yarn bobbin from falling off and displacing during rotation on the clamping mechanism 2, improving winding stability. The setting of spring 222 causes the yarn bobbin to automatically rebound to the rotating rod 23 when it is separated.

[0025] The usage method and working principle of this device are as follows: When in use, the user fixes the clamping mechanism 2 on the unwinding machine, and then puts the yarn bobbin on the outside of the clamping mechanism 2. When the yarn bobbin is on the outside of the clamping mechanism 2, it presses the pressure plate 233, thereby causing the limiting clamping plate 232 to rise at the end of the clamping mechanism 2. The limiting clamping plate 232 then limits the yarn bobbin at the end of the clamping mechanism 2, thus preventing the yarn bobbin on the clamping mechanism 2 from falling off and displacing during rotation. The pressure plate 233 presses the rotating rod 23, and the cylinder 1 controls the push rod 26 to push the push block 28 forward. The edge of the push block 28 is used to squeeze the top pressure block 25 and push it out of the telescopic groove 24, thereby squeezing and fixing the yarn bobbin outside the clamping mechanism 2. When the yarn bobbin is wound, the cylinder 1 controls the push block 28 to pull back, causing the top pressure block 25 to retract into the telescopic groove 24, thereby quickly releasing the yarn bobbin, making it easy for the user to quickly load and unload the yarn bobbin.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
