Technical Field
[0001] This utility model belongs to the technical field of winding machine equipment, specifically relating to a yarn bobbin length control device for a winding machine. Background Technology
[0002] A winding machine, also known as a yarn winding machine or yarn winding machine, is an essential piece of equipment in the post-spinning and preparation processes. Its main function is to rewind the yarn from the twisting machine or spinning machine into a larger volume, and to remove impurities or defects from the yarn and filaments during the winding process, thereby improving the labor and productivity of subsequent processes.
[0003] A winding machine is a device used to produce yarn. Its main function is to transfer yarn from one tube (the original yarn bobbin) to a new tube (the winding bobbin), gradually increasing the yarn tension during the process. The winding machine can transfer yarn from one yarn bobbin to another. During the transfer, the guide rod will reciprocate within a vertical range under the control of the winding machine to adapt to the length of the yarn bobbin being transferred. Since the lengths of different yarn bobbins are different, current winding machines are often controlled by electric guide rails. However, electric guide rails are expensive and require electronic equipment to operate, which cannot meet the needs of some small businesses. Summary of the Invention

Detailed Implementation
[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0018] Example: A yarn bobbin length control device for a winding machine, such as... Figures 1-3 As shown, it includes a horizontally arranged base 1, with vertically fixed seats 2 on both sides of the upper surface of the base 1. The upper part of the outer surface of the two seats 2 is provided with a horizontally extending groove 3 along its length. The interior of the two grooves 3 is vertically slidably connected with sliders. The two end surfaces of the two sliders extend to the inner and outer sides of the two seats 2 respectively. The two ends of the two sliders are fixedly connected with sliding seats 4. A horizontal frame 5 is horizontally fixed between the two sliding seats 4 on the inner side. Multiple yarn guide rods 7 are provided on the front surface of the horizontal frame 5.
[0019] Both uprights 2 have an adjustment structure on their outer surfaces to control the vertical movement range of the crossbeam 5.
[0020] Multiple fixing blocks 6 are fixedly connected at even intervals along the length of the front end of the upper surface of the cross frame 5, and multiple yarn guide rods 7 are respectively fixedly connected laterally to the front end surface of the multiple fixing blocks 6.
[0021] Multiple sliding seats 4 move along the height direction of the upright seat 2 under the action of the slider and the slide groove 3. The multiple sliding seats 4 are driven by the adjustment structures on both sides and are restricted by the two adjustment structures. The two adjustment structures can limit the reciprocating range of the multiple sliding seats 4 in the vertical direction, which also simultaneously limits the movement range of the cross frame 5 and the multiple yarn guide rods 7 on it.
[0022] The adjustment structures on both sides are identical. One of the adjustment structures includes a turntable 8 that is laterally rotatably connected to the lower part of the outer surface of a base 2. A slider groove 9 is provided on the outer surface of the turntable 8 along one of its radial directions. A slider block 11 is slidably connected inside the slider groove 9 along its length direction. A first hinge shaft 12 is laterally fixedly connected to the outer surface of the slider block 11. A second hinge shaft 13 is fixedly connected to the outer surface of the slider seat 4 on the same side. A hinge rod 14 is hinged between the first hinge shaft 12 and the second hinge shaft 13.
[0023] A hinge rod 14 is hinged between the outer surface of the sliding block 11 and the outer surface of the sliding seat 4 on the upright 2. During the rotation of the turntable 8, the sliding seat 4 will be driven to reciprocate vertically through the hinge rod 14. The range of this movement is affected by the distance between the sliding block 11 and the center of the turntable 8. By changing the position of the sliding block 11 on the turntable, the range of movement of the sliding seat 4 can be changed, thereby changing the range of movement of the multiple yarn guide rods 7 on the cross frame 5, so as to adapt to yarn bobbins of different lengths. The overall structure of this structure is simple, easy to operate, and low in cost, which can meet the needs of some small enterprises.
[0024] Multiple locking holes 10 are transversely opened on the inner surface of the slider groove 9 along its length direction. A through hole 15 is opened on the outer surface of the slider block 11. A tension spring 16 coaxial with the through hole 15 is fixedly connected to the outer surface of the slider block 11. An end piece 17 is fixedly connected to the outer end of the tension spring 16. A locking pin 18 adapted to the multiple locking holes 10 is fixedly connected to the inner surface of the end piece 17.
[0025] A pull ring is provided at the outer end of end piece 17.
[0026] The locking pin 18 on the sliding block 11 will be locked into the inside of a locking hole 10 under the action of the tension spring 16, thereby fixing the sliding block 11. When it is necessary to adjust the position of the sliding block 11, the end piece 17 is pulled outward by the pull ring, which causes the locking pin 18 to disengage from the inside of the locking hole 10. Then the sliding block 11 is pushed to slide until it reaches the designated position. Then the pull ring is released, and the locking pin 18 will be sent into the inside of another locking hole 10 under the action of the tension spring 16 to limit and fix the sliding block 11.
[0027] A connecting shaft 19 is rotatably connected to the lower part between the two uprights 2. The two ends of the connecting shaft 19 rotatably pass through the two uprights 2 and are fixedly connected to the inner surfaces of the two turntables 8 respectively. A motor 20 is fixedly connected to the upper surface of the base 1. Pulleys 21 are fixedly connected to the output shaft surface of the motor 20 and the outer surface of the connecting shaft 19. The two pulleys 21 are connected by belt drive.
[0028] During the operation of the motor 20, the pulley 21 on its output shaft will drive another pulley 21 connected to it to rotate, which will synchronously drive the connecting shaft 19 to rotate. The turntables 8 at both ends of the connecting shaft 19 will rotate synchronously, thereby driving the device to operate.
[0029] The principle of this utility model is as follows: A hinge rod 14 is hinged between the outer surface of the sliding block 11 and the outer surface of the sliding seat 4 on the stand 2. During the rotation of the turntable 8, the sliding seat 4 will be driven to reciprocate vertically through the hinge rod 14. The range of this movement is affected by the distance between the center of the sliding block 11 and the center of the turntable 8. By changing the position of the sliding block 11 on the turntable, the range of movement of the sliding seat 4 can be changed, thereby changing the range of movement of the multiple yarn guide rods 7 on the cross frame 5, so as to adapt to yarn bobbins of different lengths. When it is necessary to adjust the position of the sliding block 11, the end piece 17 is pulled outward by the pull ring, which causes the locking pin 18 to disengage from the inside of the locking hole 10. Then, the sliding block 11 is pushed to slide until it reaches the designated position. Then, the pull ring is released, and the locking pin 18 is sent into the inside of another locking hole 10 under the action of the tension spring 16 to limit and fix the sliding block 11.
[0030] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
