Description

TECHNICAL FIELD

[0001] The utility model relates to a winding machine technical field, concretely relates to a yarn tension monitoring and adjusting device for winding machine. BACKGROUND

[0002] The winding machine is a special equipment in the textile industry, and the winding is the last process of spinning and the first process of weaving, which plays a "bridge" role and occupies an important position in the textile field. When winding, the yarn tension needs to be adjusted and the yarn breakage needs to be detected.

[0003] The prior art such as application number: CN202221320736.3 discloses a wire guide device for winding machine, which is contacted by the contact wheel and the yarn winding around the wire guide wheel, the contact force between the contact wheel and the yarn is transmitted to the tension sensor through the lever principle of the connecting arm, the tension sensor measures the tension of the yarn, so that whether the yarn passes through can be detected, and the subsequent equipment is prevented from idling, and the distance between the seat plate and the fixed plate can be adjusted through the screw rod, the nut and the guide rod, so that the tension of the yarn is adjusted.

[0004] However, the adjustment range of the above structure is limited, and the yarn tension cannot be effectively adjusted under the condition that the yarn is loose. UTILITY MODEL CONTENTS

[0005] The utility model discloses a yarn tension monitoring and adjusting device for winding machine, which can effectively adjust the yarn tension and monitor the yarn breakage.

[0006] The utility model discloses a yarn tension monitoring and adjusting device for winding machine, which includes the base, is provided with the mounting seat on both sides of the base, is provided with no.

[0007] When in use, the above device is installed on the winding machine, and the microswitch is electrically connected to the controller of the winding machine. The yarn is passed between the No. 1 pressure wheel and the No. 2 pressure wheel. The yarn squeezes the No. 2 pressure wheel upward, and the end of the No. 2 rod body is disengaged from the microswitch. When the pressure between the No. 1 pressure wheel and the No. 2 pressure wheel is relatively small, the yarn is easier to pull during transportation, so the tension is smaller. By adjusting the nut, the bolt moves downward, so that the spring is compressed, the pressure between the No. 1 pressure wheel and the No. 2 pressure wheel becomes larger, and the yarn is not easy to pull during transportation, so the yarn tension becomes larger. When the yarn is broken, the end of the No. 2 rod body contacts the microswitch again, thereby detecting the break.

[0008] Furthermore, in order to prevent the yarn from escaping from the No. 1 and No. 2 pressure wheels during transportation, yarn guide rings are provided in the middle positions on both sides of the No. 1 and No. 2 pressure wheels, and the yarn guide rings are connected to the mounting seat through connecting rods.

[0009] The utility model provides a yarn tension monitoring and adjusting device for a winding machine, which has the beneficial effect of adjusting the pressure between the first pressure wheel and the second pressure wheel by a nut, thereby adjusting the tension of the yarn, and detecting whether the yarn is broken by a micro switch.

[0012] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0013] Example 1:

[0014] like Figure 1 、 2As shown, the utility model discloses a yarn tension monitoring and adjusting device for a winding machine, comprising a base 1, mounting seats 2 are provided on both sides of the base 1, a rod body 4 is horizontally provided between the two mounting seats 2, a No. 1 rod body 4 is rotatably provided with a No. 1 pressure wheel 12, a No. 2 rod body 6 is provided directly above the No. 1 rod body 4 and parallel to the No. 1 rod body 4, a No. 2 pressure wheel 8 is rotatably provided on the No. 2 rod body 6, and the No. 2 pressure wheel 8 is pressed on the No. 1 pressure wheel 12, a No. 1 through hole is vertically provided at both ends of the No. 1 rod body 4, and the No. 2 rod body 4 is provided with a No. 1 through hole. A No. 2 through hole is provided on the body 6 at a position corresponding to the No. 1 through hole. A bolt 5 is passed through the No. 2 through hole and the No. 1 through hole at the same end from top to bottom. A spring 7 is sleeved on the bolt 5 between the upper end head of the bolt 5 and the No. 2 rod body 6. The two ends of the spring 7 are respectively pressed against the upper end head of the bolt 5 and the No. 2 rod body 6. The lower end of the bolt 5 is located on the lower side of the No. 1 rod body 4. A nut 3 is provided at the lower end of the bolt 5. An upward micro switch 10 is provided on the mounting seat 2, and the end of the No. 2 rod body 6 is pressed against the micro switch 10.
