Description

Technical Field

[0001] This utility model belongs to the technical field of yarn preparation equipment, and in particular relates to a yarn weighing device. Background Technology

[0002] When using yarn as a raw material for production, the weight of the yarn is a factor to consider in product quality. Currently, the weight is generally measured by the yarn's usage time or the processing technology of the product to be processed.

[0003] However, existing technologies have some problems: a significant issue with the methods described above is that the amount of yarn used becomes uncontrollable when the yarn itself changes. This is especially true when using colored yarns, where precise control of the amount of each type of yarn is crucial to achieving the desired color ribbon design and reducing color error rates. In reality, this requires real-time, relatively precise control of yarn usage. Currently, the main shortcomings lie in the control and measurement methods, preventing the precise control of yarn usage. Therefore, we propose a yarn weighing device. Utility Model Content

The working box has an inner cavity, and a motor is fixedly installed inside the inner cavity. The output end of the motor passes through the working box and is connected to the turntable.

[0006] As a preferred embodiment of this invention, the outer wall of the fixed shaft is threaded with a nut.

[0007] As a preferred embodiment of this invention, a limiting shaft is fixedly connected to the middle of the upper outer wall of the turntable, and the limiting shaft is arranged in a polygonal shape.

[0008] As a preferred embodiment of this utility model, the lower outer wall of the take-up drum is provided with a mounting hole for receiving the limiting shaft, the mounting hole being arranged in a polygonal shape, and the upper outer wall of the take-up drum is provided with an inwardly recessed positioning hole.

[0009] In a preferred embodiment of this utility model, the limiting mechanism includes an outer cylinder fixedly connected to the upper outer wall of the work box. The outer cylinder has a tension groove inside, and an inner rod is movably connected inside the tension groove. The upper end of the inner rod extends to the outside of the outer cylinder, and a connecting rod is fixedly connected to the upper end of the inner rod. A positioning rod that fits into a positioning hole is fixedly connected to the lower outer wall of the other end of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses an electronic weighing platform to weigh the yarn bobbin. A motor drives a turntable to rotate, which facilitates the feeding of yarn onto the take-up bobbin. During the rotation of the turntable, the extended block contacts the touch switch of the metering device, so that the turntable contacts the metering device every time it rotates. The metering device counts the number of contacts, which makes it easy to calculate the number of turns of yarn taken up by the take-up bobbin, thus making it easy to know the length of the yarn and achieve the purpose of precise control of the amount of yarn used.

[0015] 2. This utility model, by pulling the connecting rod, drives the inner rod to move inside the stretching groove, which in turn drives the stretching block. The stretching block pulls the stretching spring, causing the inner rod to move out of the stretching groove, making it easier for the positioning rod to move to the upper end of the take-up drum. The rebound of the stretching spring drives the inner rod to reset, making it easier for the positioning rod to reset and extend into the positioning hole. With the use of the limiting shaft, it is easy to limit and fix the take-up sleeve, making it convenient to take up the yarn. Attached Figure Description

[0025] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Example 1:

[0027] like Figure 1 and Figure 2 As shown in the figure, a yarn weighing device provided by this utility model embodiment includes a working box 1. A control panel 11 is connected to the front outer wall of the working box 1, and a display screen is connected to the outer wall of the control panel 11. An electronic weighing platform 12 and a measuring device 3 are fixedly connected to the upper end of the working box 1, and a turntable 15 is movably connected to the upper end of the working box 1. The measuring device 3 is located between the electronic weighing platform 12 and the turntable 15. A fixed shaft 13 is fixedly connected to the upper end of the electronic weighing platform 12. A yarn bobbin 2 for winding yarn is sleeved on the outer wall of the fixed shaft 13. An extension block 151 that contacts the measuring device 3 is fixedly connected to the outer wall of the turntable 15. A detachable take-up bobbin 5 is connected to the upper end of the turntable 15. A stretchable [unclear text - possibly a continuation of the previous paragraph] is fixedly connected to the upper end of the working box 1. A limiting mechanism 4 is provided, with its other end connected to the take-up drum 5. The working box 1 has an inner cavity 16, inside which a motor 17 is fixedly installed. The output end of the motor 17 passes through the working box 1 and is connected to the turntable 15. The weight of the yarn drum 2 is weighed by the electronic weighing platform 12. The motor 17 drives the turntable 15 to rotate, which facilitates the guide of the yarn onto the take-up drum 5. During the rotation of the turntable 15, it contacts the touch switch of the measuring device 3 through the extension block 151, so that the turntable 15 contacts the measuring device 3 every time it rotates. The measuring device 3 counts the number of touches, which is convenient for calculating the number of turns of the take-up drum 5, thus making it easy to know the length of the yarn and achieving the purpose of precise control of the amount of yarn used.

[0028] like Figure 1 As shown, a nut 14 is threaded onto the outer wall of the fixed shaft 13; the nut 14 is provided to limit the position of the spool placed on the fixed shaft 13, which facilitates the wire feeding operation.

[0029] like Figure 2 As shown, a limiting shaft 152 is fixedly connected to the middle of the upper outer wall of the turntable 15. The limiting shaft 152 is arranged in a polygonal shape, and the polygonal shaft facilitates the connection of the take-up drum 5.

[0030] like Figures 3 to 4 As shown, the lower outer wall of the take-up drum 5 is provided with a mounting hole 52 for receiving the limiting shaft 152. The mounting hole 52 is arranged in a polygonal shape. The upper outer wall of the take-up drum 5 is provided with an inwardly recessed positioning hole 51. The mounting hole 52 facilitates the insertion of the take-up drum 5 into the limiting shaft 152, which facilitates the take-up operation of the yarn.

[0031] like Figure 5As shown, the limiting mechanism 4 includes an outer cylinder 41 fixedly connected to the upper outer wall of the working box 1. The outer cylinder 41 has a tension groove 411 inside, and an inner rod 42 is movably connected inside the tension groove 411. The upper end of the inner rod 42 extends to the outside of the outer cylinder 41, and a connecting rod 43 is fixedly connected to the upper end of the inner rod 42. A positioning rod 44, which fits into a positioning hole 51, is fixedly connected to the lower outer wall of the other end of the connecting rod 43. The positioning rod 44, the connecting rod 43, and the inner rod 42 are arranged in a U-shape. A tension block 421 is fixedly connected to one end of the inner rod 42 inside the tension groove 411. A tension spring 45 is connected to the lower end of the 1, and the other end of the tension spring 45 is connected to the inner wall of the tension groove 411. By pulling the connecting rod 43, the inner rod 42 is moved inside the tension groove 411, which in turn moves the tension block 421. The tension block 421 pulls the tension spring 45, causing the inner rod 42 to move outside the tension groove 411, so that the positioning rod 44 can move to the upper end of the take-up drum 5. The tension spring 45 rebounds, causing the inner rod 42 to reset, which in turn causes the positioning rod 44 to reset. The positioning rod 44 is reset and extends into the positioning hole 51. With the use of the limiting shaft 152, the take-up sleeve can be limited and fixed, which is convenient for taking up the yarn.

[0032] like Figure 6 and Figure 7As shown, the measuring device 3 includes a signal transmitter 31 fixedly installed on the upper outer wall of the working box 1. The signal transmitter 31 is wirelessly connected to the control panel 11. A connecting seat 32 and a touch sensor 33 are fixedly connected to the right side of the signal transmitter 31. The outer wall of the right side of the connecting seat 32 is provided with an inwardly recessed movable groove 321. A movable plate 34 is movably connected inside the movable groove 321. The upper and lower outer walls of the connecting seat 32 are provided with inwardly recessed limiting holes 322, which communicate with the movable groove 321. A connecting block 36 is fixedly connected to the outer wall of the movable plate 34 near the connecting seat 32. The connecting block 36 extends into the movable groove 321. A connecting shaft 361 is fixedly connected to the outer walls of both the upper and lower ends of the connecting block 36. The connecting shaft 361 extends into the limiting hole 322. A torsion spring 362 is sleeved on the outer wall of the connecting shaft 361. The upper and lower ends are fixedly connected to the connecting seat 32 and the connecting block 36, respectively. The front outer wall of the movable plate 34 is fixedly connected to a touch pad 35 that contacts the touch sensor 33. During the rotation of the turntable 15, the extension block 151 is driven to rotate. During the rotation of the extension block 151, it contacts the movable plate 34, causing the movable plate 34 to rotate. The movable plate 34 rotates and contacts the touch sensor 33 through the touch pad 35. The touch sensor 33 uploads the number of touches to the display screen on the control panel 11 through the signal transmitter 31 for calculation. When the clamping block rotates away from the movable plate 34, the movable plate 34 is not under force and is reset by the torsion spring 362. Thus, the turntable 15 contacts the measuring device 3 for each rotation. The measuring device 3 calculates the number of rotations of the turntable 15. Based on the diameter of the take-up drum 5, the length of the yarn can be easily counted for subsequent use.

[0033] Working principle of Example 1:

[0034] In use, the motor 17 is started via the control panel 11, which drives the turntable 15 to rotate. During the rotation of the turntable 15, the extension block 151 rotates. The extension block 151 contacts the movable plate 34 during rotation, causing the movable plate 34 to rotate. The movable plate 34 rotates and contacts the touch sensor 33 via the touch pad 35. The touch sensor 33 transmits the number of touches to the display screen on the control panel 11 via the signal transmitter 31 for calculation. When the clamping block rotates away from the movable plate 34, the movable plate 34 is no longer under force and is reset by the torsion spring 362. Thus, the turntable 15 contacts the measuring device 3 for each rotation, and the measuring device 3 calculates the number of rotations of the turntable 15. Based on the diameter of the take-up drum 5, the length of the yarn can be easily counted for subsequent use.
