[0001] The utility model relates to the technical field of textile machinery, in particular to a full yarn quantity regulating device of a yarn storage device. Background Art

[0002] The yarn storage device mainly includes a housing, a main shaft and a yarn storage drum installed thereon. The yarn storage drum is sleeved with a yarn pressing ring and a tension ring. The main shaft is located at the center of the yarn storage drum, and the main shaft drives the yarn storage drum to rotate to store yarn. The stored yarn is the yarn stored on the feeding wheel, and the fed yarn is the yarn output after passing through the tension ring.

[0003] The yarn storage process of the yarn storage device is as follows: the rotation of the motor drives the yarn storage drum to rotate. During the yarn storage process, the yarn on the yarn storage drum continues to increase. As the yarn increases, the yarn pressure circle continues to move up. When the yarn pressure circle moves up to a certain extent, the contact with the switch device is disconnected. At this time, the motor stops rotating and the yarn storage stops. As the line transmission process proceeds, the yarn on the yarn storage drum continues to decrease, and the yarn pressure circle also moves down. When it moves down to a certain extent, the switch device is triggered to open, and the motor continues to work, driving the yarn storage, and so on. The existing yarn storage device cannot adjust the full yarn amount of the yarn storage device according to needs, that is, the amount of yarn wound on the yarn storage drum when the full yarn triggers the shutdown. Therefore, it is necessary to design an adjustment device that is easy to adjust the amount of yarn storage. Summary of the invention

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] In the prior art, the yarn storage device includes a body 10, a control circuit board is arranged inside the body 10, a yarn storage drum and a motor are arranged on the body 10, a yarn pressing ring 30 and a tension ring are arranged on the top and bottom of the yarn storage drum respectively, the yarn pressing ring 30 rotates with the yarn storage drum, and the tension ring keeps the yarn in a stable and unchanged tension state when output. Among them, the motor is electrically connected to the control circuit board, the control circuit board controls the operation of the motor, and the motor drives the yarn storage drum to operate to complete the storage and transportation of the yarn. For details, please refer to a miniature yarn storage device disclosed in a Chinese patent (authorization announcement number CN210163608U).

[0024] like Figure 1-5 As shown, a full yarn amount adjustment device for a yarn storage device comprises a body 10, a swing block 20 pivotally connected to the lower end of the body 10, and a yarn pressing ring 30 rotatably connected to the swing block 20, the yarn pressing ring 30 is sleeved on the outer periphery of the yarn storage drum and can rotate synchronously with the yarn storage drum, and a toggle rod 21 is provided on the other side of the swing block 20 relative to the yarn pressing ring 30, and the body 10 is provided with a fixed column 11 and a control circuit board, and a tension spring 12 is connected between the fixed column 11 and the toggle rod 21. In an initial state, the toggle rod 21 is deflected to a side facing the fixed column 11, that is, facing a side away from the switch device 50 under the tension of the tension spring 12, so that the swing block 20 is low at one end and high at the other end in the initial state, and correspondingly, the yarn pressing ring 30 is also in a state of one end being low and the other end being high, specifically, the end adjacent to the toggle rod 21 is low, and the end adjacent to the switch device 50 is high.

[0025] The adjusting device also includes a zero position block 40 which is fixed in the machine body 10 and has an adjustable position, and a switch device 50 which is fixedly installed on the upper end of the zero position block 40. The switch device 50 is electrically connected to the control circuit board. The toggle rod 21 extends into the machine body 10 and is arranged opposite to the switch device 50. When the yarn storage drum is full of yarn, the toggle rod 21 can cooperate with the micro switch trigger to enable the control circuit board to control the motor of the yarn storage device to stop rotating. The zero position block 40 is provided with an activity space 41 for the toggle rod 21 to swing back and forth. The position of the zero position block 40 in the machine body 10 is adjusted to adjust the initial distance between the switch device 50 and the toggle rod 21, thereby adjusting the full yarn amount of the yarn storage device.

[0026] When storing yarn, the motor rotates to drive the yarn storage drum to rotate. During the yarn storage process, the yarn is continuously increased on the yarn storage drum. With the increase of yarn, the lower end of the yarn pressing circle 30 is continuously moved upward, thereby driving the swing block 20 and the toggle rod 21 to overcome the tension of the tension spring 12 and swing toward the side close to the switch device 50. When the lower end of the yarn pressing circle 30 moves up to a certain extent, the toggle rod 21 swings to a position in contact with the switch device 50 and triggers it. At this time, the control circuit board controls the motor to stop rotating, and the yarn storage stops.

[0027] The zero position block 40 is provided with a strip groove 42, and the body 10 is provided with an assembly hole 13 at a position corresponding to the strip groove 42. The zero position block 40 is fixedly crimped into the body 10 by connecting the assembly hole 13 with a fastener. The position of the zero position block 40 is adjusted by adjusting the position of the strip groove 42 relative to the assembly hole 13. When the position of the zero position block 40 needs to be adjusted, the fastener is unscrewed and the position of the zero position block 40 is slightly moved, and then the zero position block 40 is fixed by connecting the fastener with the assembly hole 13.

[0028] The zero position block 40 is provided with two groups of strip grooves 42, and the body 10 is provided with a group of assembly holes 13 corresponding to the position of each group of strip grooves 42. The zero position block 40 is fixedly crimped in the body 10 by fasteners connected to the corresponding assembly holes 13. By setting two groups, it can be ensured that when one group of fasteners is not screwed into place or loosened, the other group can still fix the zero position block 40 in the set position, that is, the installation stability of the zero position block 40 can be guaranteed.

[0029] Two guide ribs 14 are arranged at intervals in the body 10, and the zero position block 40 is at least partially arranged between the two guide ribs 14 and cooperates with the two guide ribs 14 for guiding. The guide ribs 14 are used to limit the sliding direction of the zero position block 40 when adjusting its position. Specifically, in the utility model, the zero position block 40 is provided with a horn portion, which includes two horns 43, and guide ribs 14 are arranged on both sides of at least one horn 43. The guide ribs 14 guide the movement of the zero position block 40, so that the position of the zero position block 40 relative to the assembly hole 13 can be easily adjusted.

[0030] The body 10 is provided with a through slot 15 for the toggle lever 21 to swing, and the activity space 41 corresponds to the position of the through slot 15 . Both the through slot 15 and the activity space 41 are strip-shaped notches.

[0031] A bearing seat 22 is provided at the lower end of the swing block 20, and the yarn pressing ring 30 is rotatably arranged on the bearing seat 22 through a bearing (not shown in the figure). The yarn pressing ring 30 is a disc structure with a through hole in the center, and the diameter of the through hole is larger than the outer diameter of the motor. The yarn pressing ring 30 is provided with a plurality of mounting holes near the circumference, and the mounting holes are evenly distributed along the circumference of the central axis and matched with the yarn storage drum. The mounting holes are sleeved on the yarn storage drum, so that the yarn pressing ring 30 can rotate with the rotation of the yarn storage drum.

[0032] Lugs 23 are provided on both sides of the swing block 20, and mounting holes are provided on the lugs 23. Two sets of fixing seats 16 are provided on the body 10, and the lugs 23 are pivotally connected to the fixing seats 16 through a pivot (not shown in the figure) so that the swing block 20 can swing relative to the fixing seats 16.

[0033] Furthermore, in the initial state, the toggle rod 21 is in a separated state from the switch device 50 under the tension of the tension spring 12; the yarn is continuously increased on the yarn storage drum, the lower end of the yarn pressing circle 30 is continuously moved upward and drives the toggle rod 21 to swing toward the trigger switch device 50. When the lower end of the yarn pressing circle 30 moves upward to a certain extent, the toggle rod 21 swings to cooperate with the trigger of the switch device 50, and the control circuit board controls the motor to stop rotating.

[0034] The switch device 50 is a micro switch, and the micro switch is electrically connected to the control circuit board of the yarn storage device.

[0035] In summary, the utility model has the following beneficial effects:

[0036] The full yarn amount adjustment device of the utility model adjusts the position of the zero block 40 in the machine body 10 to adjust the initial distance between the switch device 50 and the toggle rod 21, that is, adjusts the angle required for the toggle rod 21 to swing from the initial position to the trigger position, and accordingly adjusts the upward movement of the lower end of the yarn pressing circle 30 during the yarn storage process, thereby adjusting the full yarn amount of the yarn storage device. In addition, the adjustment method of the utility model is relatively simple and convenient.

[0037] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
