Description

Technical Field

[0001] The utility model relates to the technical field of yarn drawing machines, in particular to a yarn drawing machine which can prevent the inertia of a roller from winding yarn when the machine is stopped. Background Art

[0002] The yarn drawing machine is a kind of equipment used in the textile industry, which is mainly used to pull the yarn out of the spindle or the yarn tube and form a certain tension. It is an important process in the spinning process, which is used to prepare the yarn for weaving or knitting. The working principle of the yarn drawing machine is to draw the yarn from the spindle or the yarn tube through the yarn drawing mechanism, adjust the tension of the yarn through the tension device, and then transmit it to the subsequent process. In the whole process, it is necessary to pay attention to the tension control and smooth transmission of the yarn to ensure the quality and processing effect of the yarn.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing yarn drawing machine stops using, the yarn roller will rotate under inertia. The existing structure only brakes the driving wheel to stop, and does not make too much design for the roller. The roller will entangle the yarn when rotating by inertia, affecting the subsequent use of the equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a yarn drawing machine that prevents the roller from inertia winding yarn when the machine is stopped, so as to solve the problem raised in the above background technology that when the existing yarn drawing machine stops using, the yarn roller will rotate under inertia, and the existing structure only brakes the driving wheel to stop, and there is not much design for the roller. The roller will entangle the yarn when rotating by inertia, affecting the subsequent reuse of the equipment.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a yarn drawing machine for preventing the inertia winding of a roller when the machine is stopped, comprising:

[0008] The main body assembly includes a base, a vertical plate fixedly connected to the top surface of the base, a side frame fixedly connected to both ends of one side of the vertical plate, a rotating shaft arranged on the side of the side frame, and a roller connected to the rotating shaft;

[0009] The regulating component comprises an electromagnetic brake sleeved on the surface of the rotating shaft and a connecting wire connected to the surface of the electromagnetic brake.

[0010] Furthermore, a bracket is fixedly connected to one side of the top surface of the base;

[0011] Wherein, a driving wheel is rotatably connected to the middle part of the top surface of the bracket.

[0012] Furthermore, a take-up wheel is rotatably connected to one side of the top surface of the base, and a controller is fixedly connected to one side of the top surface of the base.

[0013] Furthermore, a first driven wheel and a second driven wheel are respectively provided on both sides of the driving wheel;

[0014] Wherein, the first driven wheel, the second driven wheel and the driving wheel are equal in length.

[0015] Furthermore, both ends of the first driven wheel and the second driven wheel are provided with rotating shafts of the same structure, and electromagnetic brakes of the same structure are sleeved on the rotating shafts.

[0016] Furthermore, the driving wheel, the first driven wheel, the second driven wheel and the roller wheel are in contact with the yarn respectively.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] By cooperating with the main assembly and the adjustment assembly, the driving wheel and the roller wheel can be locked simultaneously during use, and the electromagnetic locking has a fast response speed, which completely avoids yarn entanglement due to inertia and affects the subsequent use of the equipment.

[0019] During actual use, the equipment is turned on, the driving wheel rotates to drive the yarn to the take-up wheel, the take-up wheel rotates first, the yarn rotates on the roller, and the roller rotates synchronously under the action of the yarn. When the equipment stops using, the three distributed electromagnetic brakes automatically lock the roller, the first driven wheel and the second driven wheel to prevent them from continuing to rotate due to inertia.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figure 1-3 As shown, this embodiment is a yarn drawing machine for preventing the inertia winding of the roller at the time of stopping, comprising:

[0031] The main assembly includes a base 11, a vertical plate 14 fixedly connected to the top surface of the base 11, a side frame 15 fixedly connected to both ends of one side of the vertical plate 14, a rotating shaft 16 arranged on the side of the side frame 15, and a roller 17 connected to the rotating shaft 16;

[0032] The adjusting assembly includes an electromagnetic brake 21 sleeved on the surface of the rotating shaft 16 and a connecting wire 22 connected to the surface of the electromagnetic brake 21;

[0033] A bracket 12 is fixedly connected to one side of the top surface of the base 11;

[0034] The middle part of the top surface of the bracket 12 is rotatably connected to the driving wheel 13.

[0035] A take-up wheel 18 is rotatably connected to one side of the top surface of the base 11, and a controller 19 is fixedly connected to one side of the top surface of the base 11.

[0036] A first driven wheel 31 and a second driven wheel 32 are respectively disposed on both sides of the driving wheel 13;

[0037] The first driven wheel 31, the second driven wheel 32 and the driving wheel 13 are of equal length;

[0038] Working principle:

[0039] When the device is turned on, the driving wheel 13 rotates to drive the yarn to be transported to the take-up wheel 18. The take-up wheel 18 rotates first, and the yarn rotates on the roller 17. The roller 17 rotates synchronously under the action of the yarn. When the device stops using, the three distributed electromagnetic brakes 21 automatically lock the roller 17, the first driven wheel 31 and the second driven wheel 32 to prevent them from continuing to rotate due to inertia.

[0040] This step can avoid the problem of yarn entanglement caused by the roller 17 continuing to rotate under the action of inertia when the equipment stops, which is convenient for the next use of the equipment.
