[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1

[0031] Refer to Figures 1-3 , an electric wire winder, comprising a first base 1, a motor 2 disposed in the first base 1, and a rotating shaft 3 disposed on the first base 1; the included angle between the rotating shaft 3 and the horizontal plane is 30° - 50°; the rotating shaft 3 is connected to a winding column 4 through a bearing, that is, the winding column 4 is movably connected to the rotating shaft 3 and is not driven by the rotating shaft 3; a winding guide rod 5 is disposed outside the winding column 4; the winding guide rod 5 is fixedly connected to the rotating shaft 3; the free end of the winding guide rod 5 is flush with the upper part of the winding column 4; the free end of the winding guide rod 5 is of a spiral structure; the motor 2 drives the rotating shaft 3 to rotate; when the pulling force increases, the bending degree of the winding guide rod 5 increases.

[0032] In this embodiment, the included angle between the rotating shaft 3 and the horizontal plane is fixed at 45°. Compared with the vertical arrangement, it is more conducive to the introduction of the silk thread; because when the silk thread is input from the external tubular fabric fixing unit, it is generally input horizontally. If it is still input horizontally onto the winding column 4, then there is no need to provide the winding guide rod 5.

[0033] In this embodiment, by setting the angle between the rotating shaft 3 and the horizontal plane at a certain angle, the wire guiding rod 5 can change the angle of the horizontally input silk thread and wind it around the winding column 4. During this process, if the silk thread is pulled, the wire guiding rod 5 will bend to a certain extent, playing a buffering role to avoid wire breakage.

[0034] Preferably, the motor 2 is a servo motor 2 or a stepper motor 2; a chip for detecting the current value of the motor 2 is provided in the first base 1; the chip is used to stop the motor 2 after detecting that the current of the motor 2 exceeds a preset value.

[0035] In the art, this type of chip can be a TMC drive chip such as TMC2209, which has a UART mode.

[0036] Preferably, there are 2 wire guiding rods 5, which are arranged symmetrically with the rotating shaft 3 as the center. Since the winding column 4 is inclined and the wire guiding rod 5 has a certain self-weight, designing two wire guiding rods 5 can balance the weight and make the rotation of the motor 2 smoother; it should be noted that during use, only need to let the silk thread pass through one wire guiding rod 5, and the other wire guiding rod 5 is idle.

[0037] Preferably, the wire guiding rod 5 is L-shaped. This shape design of the wire guiding rod 5 is easier to bend and can absorb a suddenly increased tensile force. In this embodiment, the wire guiding rod 5 is made of stainless steel wire with a certain diameter, such as its diameter is 3 - 5 mm.

[0038] To facilitate connection to the desktop, the first base 1 is provided with a quick-release locking member 6 for connecting to the edge of the peripheral desktop. The quick-release locking member 6 can be realized by the cooperation of a U-shaped clamping plate and a bolt. Weld the first base 1 on the U-shaped clamping plate, the U-shaped clamping plate is stuck on the desktop edge, and then tighten and fix it on the desktop edge through a bolt passing through one side of the U-shaped clamping plate.

[0039] Preferably, a groove 7 is provided at the top of the winding column 4; the groove 7 is used to clip the end of the silk thread so that when the wire guiding rod 5 rotates, the silk thread can be wound around the outer wall of the winding column 4.

[0040] Preferably, the first base 1 extends along the projection direction of the rotating shaft 3 on the horizontal plane; a wire guiding module 8 is provided at the end of the first base 1; the wire guiding module 8 is used to make the silk thread enter the free end of the wire guiding rod 5 along the projection direction of the rotating shaft 3 on the horizontal plane. The wire guiding module 8 is used to turn the silk thread output by the peripheral cylindrical fabric fixing unit by 90° and input it to the free end of the wire guiding rod 5; similar to the material of the wire guiding rod 5, it is also made of stainless steel wire and has a buffering effect; its top also has a spiral structure.

[0041] Embodiment 2

[0042] refer to Figures 4-6 A tubular fabric thread remover comprises two electric thread take-ups as described in Example 1; a tubular fabric fixing unit is provided between the two electric thread take-ups; the tubular fabric fixing unit comprises a second base 9 and a tubular fabric fixer 10; the tubular fabric fixer 10 is outer-mounted with the tubular fabric; the tubular fabric fixer 10 is detachably connected to the second base 9; the tubular fabric fixer 10 is connected to the second base 9 or is placed on the second base 9 in a freely rotatable manner with its own axis as the center.

[0043] During the application process, the usage is:

[0044] First, put the socks on the tubular fabric holder 10;

[0045] Then, find the ends of the two silk threads of the socks, pull out a length, pass them through the spiral structure of the wire module 8 (wind several turns on the spiral structure), and through the spiral structure of the free end of the winding guide rod 5 (wind several turns on the spiral structure), and finally wind the ends of the silk threads into the corresponding grooves on the top of the winding post 4;

[0046] Finally, the motor 2 is started, the winding post 4 rotates, and the silk thread is wound onto the corresponding winding post 4; due to the existence of tension, the tubular fabric holder 10 is driven to rotate; during the disassembly process, if a part of the sock is knotted, but the motor 2 is still rotating, the tension will increase, and this increased tension will be buffered by the winding guide rod 5. When the operator sees that the winding guide rod 5 is bent, he will actively stop the motor 2, or, if it is equipped with a relevant current detection chip, the continuous increase in tension will cause the chip to issue a command to stop the motor 2.

[0047] Preferably, a sleeve 11 is provided on the second base 9; a column 12 is provided in the sleeve 11, and the tubular fabric holder 10 is a cup; the side wall of the cup is used to sleeve the tubular fabric; the cup is buckled on the column 12;

[0048] The advantages of this design are: the cup body has various specifications and can be adapted to socks of different specifications;

[0049] Although the cup is just buckled on the column 12, there is no problem of tilting. In the absence of tension, the cup will indeed tilt, but as long as the two motors 2 apply tension synchronously, the cup will buckle on the column 12.

[0050] Moreover, this design form has a very low cost and can be realized by using an ordinary plastic cup with a certain hardness.

[0051] More preferably, a plurality of annular ridges are preferably designed on the outer wall of the plastic cup to better fix samples such as socks and prevent the socks from detaching from the smooth outer wall of the cup during the pulling process.

[0052] In a laboratory scenario, the cylinder 12 is a mineral water bottle filled with water.
