[0034] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0035] Example 1

[0036] like Figs. 1-3 As shown in this embodiment, a yarn winding device for automatic quantitative cutting using the gravity of the yarn is provided, including a base plate 1; a cutting assembly 2 is provided on the base plate 1, the cutting assembly 2 includes a cutting table 201, the cutting table 201 is provided on the upper surface of the base plate 1, a gantry frame 202 is provided above the cutting table 201, a cutting blade 204 is slidably connected to the gantry frame 202 via a cylinder 203, the cylinder 203 is fixedly connected to the gantry frame 202, and the lower end of the output shaft of the cylinder 203 is fixedly connected to the side wall of the cutting blade 204; A support assembly 3 is provided on the upper surface of the base plate 1; a winding roller 4 is supported and rotated above the base plate 1 by the support assembly 3 for winding the yarn; a pressure plate 205 is provided on the gantry frame 202, and a slot is provided on the side wall of the pressure plate 205 for the lower end of the cutting blade 204 to pass through. The upper parts of both ends of the pressure plate 205 are fixedly connected to the first guide post 206, the upper end of the first guide post 206 is slidably sleeved on the side wall of the cutting blade 204, and a spring 207 for pressing the pressure plate 205 downward is sleeved on the first guide post 206.

[0037] The winding end of the yarn passes through the cutting table 201 and is wound on the winding roller 4. As the winding roller 4 rotates, the yarn is wound on the winding roller 4. When the yarn is wound on the winding roller 4 to a certain weight, the cylinder 203 is started, so that the cylinder 203 drives the cutting knife 204 and the pressing plate 205 to slide downward. The pressing plate 205 first presses the yarn on the cutting table 201. As the cylinder 203 continues to drive the cutting knife 204 and the pressing plate 205 to slide downward, the pressing plate 205 presses the yarn and does not move. The cutting knife 204 continues to move downward by compressing the spring 207. In this process, the pressing plate 205 always presses the yarn to fix the cut yarn end, which facilitates the next winding work.

[0038] Two ear plates 5 are arranged on the bottom plate 1 and away from the support assembly 3. Two rollers 6 are rotatably connected between the two ear plates 5. A gap for conveying the yarn is arranged between the two rollers 6.

[0039] A cutting groove 2011 is formed in the upper surface of the cutting table 201 and directly below the cutting knife 204.

[0040] Embodiment Two

[0041] As shown in Figs. 1-3 the first embodiment, the support assembly 3 includes a lower support column 301 and an upper support column 302. The lower support column 301 is arranged on the upper surface of the bottom plate 1. The upper support column 302 is arranged above the lower support column 301. A weight sensor 303 is arranged between the upper support column 302 and the lower support column 301. A rotating roller 304 is rotatably arranged on the upper support column 302.

[0042] As the yarn is continuously wound on the winding roller 4, the weight also increases. At this time, the weight of the yarn will correspondingly compress the weight sensor 303. When the weight sensor 303 is compressed to a certain amount, the winding of the yarn is completed, and the winding roller 4 stops rotating. At the same time, the cutting assembly 2 operates to cut the yarn.

[0043] The upper end of the lower support column 301 is fixedly connected with a plurality of second guide columns 7. The upper ends of the plurality of second guide columns 7 are slidably sleeved into the upper support column 302.

[0044] The working process is as follows: the yarn is drawn from the yarn supply device, and wound on the winding roller 4 rotatably installed on the support assembly 3 after passing through the cutting table 201. As the yarn is continuously wound, the weight on the winding roller 4 gradually increases. This weight change is transmitted to the weight sensor 303 through the upper support column 302.

[0045] When the weight of the spun yarn accumulates to a preset value, the weight sensor 303 sends a signal to the control system. Upon receiving the signal, the control system determines that the cutting conditions have been met and then activates the cylinder 203 in the cutting assembly 2. The cylinder 203 responds to the command, pushing the cutting blade 204 and the pressure plate 205 downwards synchronously. The pressure plate 205 first contacts and firmly presses down on the spun yarn to prevent it from moving during the cutting process. Subsequently, the cutting blade 204 continues to descend under the action of the compression spring 207, completing the cutting action of the spun yarn.

[0046] At the same time, the control system can also send a stop signal to the motor driving the winding roller 4 to ensure that the winding roller 4 remains stationary during the cutting process, avoiding the impact on the cutting effect due to continued rotation. After cutting, the yarn ends are firmly held on the cutting table by the pressure plate 205, making it easy for operators or subsequent machinery to pick up, preparing for the next round of winding operations.

[0047] Example 3

[0048] like Figs. 1-3 As shown, based on Embodiment 1, in order to facilitate the disassembly of the winding roller 4, a support roller 9 for connecting the winding roller 4 is fixedly sleeved on the rotating roller 304. A fixed baffle 10 is fixedly connected to one end of the support roller 9 near the upper support column 302, and a movable baffle 11 is threadedly engaged to the other end of the support roller 9 away from the upper support column 302.

[0049] A limiting groove 12 is provided on the side wall of the support roller 9, and a limiting block 13 that cooperates with the limiting groove 12 is provided on the side wall of the center hole of the winding roller 4 to ensure that the winding roller 4 and the support roller 9 rotate synchronously.

[0050] A motor 8 for driving the rotating roller 304 to rotate is provided on the side wall of the upper support column 302.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model.
