TECHNICAL FIELD

[0001] The utility model relates to the technical field of textile thread, especially a textile thread tension adjusting device. BACKGROUND

[0002] The tension of the textile thread is very important during winding or unwinding, and the textile thread will be broken if too tight or loose, so a tension adjusting structure is usually arranged to adjust the tension of the textile thread, such as the yarn tension adjusting assembly disclosed in patent application No. CN202222948922.8, which adjusts the tension of the yarn by rotating the handle, driving the rotating shaft, rotating the fixed plate, rotating the first bevel gear, rotating the second bevel gear, and moving the movable seat up and down, so that the distance between the yarn feeding wheel at the top end of the movable seat and the yarn feeding wheel fixed at the top end of the fixed seat is changed, thereby changing the tension of the yarn to meet the working needs.

[0003] The existing textile thread tension adjusting device is mainly adjusted manually, and cannot be adjusted in real time during the movement of the yarn, so the efficiency of this textile thread tension adjusting method is very low. UTILITY MODEL CONTENT

[0004] The utility model solves the technical problem of providing a textile thread tension adjusting device to solve the problem of low efficiency and real-time adjustment of the existing textile thread tension adjusting method described in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a textile thread tension adjusting device, comprising

[0006] A mounting plate;

[0007] Two first wire tubes are arranged at both ends of the mounting plate;

[0008] A movable frame is movably arranged on the mounting plate, and the moving direction of the movable frame is perpendicular to the plane where the mounting plate is located;

[0009] A spring is arranged on the side of the movable frame opposite to the mounting plate;

[0010] A moving plate is arranged on the end of the spring opposite to the movable frame;

[0011] A guide column is arranged on the moving plate and slides through the side wall of the spring and the movable frame;

[0012] A pressure sensor is arranged on the moving plate;

[0013] A second wire tube is arranged on the stress surface of the pressure sensor.

[0014] Preferably, both ends of the first and second wire tubes are outwardly flared.

[0015] Preferably, the stress surface of the pressure sensor is provided with a second positioning plate, a second clamping plate is clamped on the second positioning plate, and the second wire tube is clamped by the second positioning plate and the second clamping plate.

[0016] Preferably, the end of the mounting plate is provided with a first positioning plate, a first clamping plate is clamped on the first positioning plate, and the first wire tube is clamped by the first positioning plate and the first clamping plate.

[0017] Preferably, the mounting plate is provided with a pneumatic cylinder, the output end of the pneumatic cylinder is fixedly connected with a moving frame, and the moving frame is provided with a plurality of guide rods slidingly penetrating the mounting plate.

[0018] Preferably, the mounting plate is provided with an electric control box, the electric control box is provided with a PLC controller and a control panel, and the PLC controller is electrically connected with the control panel, the pressure sensor and the pneumatic cylinder.

[0019] The beneficial effects of the above technical solutions are:

[0020] The pressure sensor can sense the pressure of the textile thread applied to the second wire tube, and when the pressure is greater than or less than the set value, the moving frame will move, thereby maintaining the pressure of the textile thread on the second wire tube and maintaining the tension of the textile thread. The spring can make the pressure applied by the textile thread change elastically within a small range, thereby avoiding the breakage of the textile thread. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0025] The embodiment of the present application will be described in detail below with reference to the drawings.

[0026] As​Figures 1-3 In the first embodiment, a textile thread tension adjusting device comprises

[0027] a mounting plate 10;

[0028] two first thread guides 30, respectively arranged at two ends of the mounting plate 10;

[0029] a moving frame 40 movably arranged on the mounting plate 10, the moving direction of the moving frame 40 being perpendicular to the plane on which the mounting plate 10 lies;

[0030] a spring 51, one end of which is arranged on a side of the moving frame 40 opposite to the mounting plate 10;

[0031] a moving plate 50, arranged on the spring 51 opposite to the moving frame 40;

[0032] a guide column 52, one end of which is arranged on the moving plate 50 and the other end of which slides through the side wall of the spring 51 and the moving frame 40;

[0033] a pressure sensor 60, arranged on the moving plate 50;

[0034] a second thread guide 70, arranged on the stress surface of the pressure sensor 60.

[0035] The first embodiment is implemented as follows:

[0036] In use, the textile thread is threaded through the first thread guide 30 and the second thread guide 70. When the textile thread has tension, the textile thread will apply pressure to the pressure sensor 60 through the second thread guide 70. When the pressure sensed by the pressure sensor 60 is greater than a set value, the moving frame 40 will move towards the position of the mounting plate 10, so that the pressure sensed by the pressure sensor 60 reaches the set range. When the pressure sensed by the pressure sensor 60 is less than the set value, the moving frame 40 will move away from the mounting plate 10 until the pressure sensed by the pressure sensor 60 reaches the set range. This can dynamically adjust the tension of the textile thread without manual adjustment.

[0037] Please refer to Figure 1 , 2 , 3, both ends of the first thread guide 30 and the second thread guide 70 are outwardly flared.

[0038] The first thread guide 30 and the second thread guide 70 are arranged in a double-head flared shape, which can reduce the wear of the textile thread.

[0041] Please refer to Figure 1 、 2 , 3, the end of the mounting plate 10 is provided with a first positioning plate 31, the first positioning plate 31 is clamped with a first clamping plate 32, and the first wire tube 30 is clamped by the first positioning plate 31 and the first clamping plate 32.

[0042] The first wire tube 30 is clamped by the first clamping plate 32 and the first positioning plate 31, which facilitates the disassembly and maintenance of the first wire tube 30.

[0044] The cylinder 41 can drive the moving frame 40 to move on the mounting plate 10, and the guide rods 42 can increase the stability of the moving frame 40.

[0045] Please refer to Figure 1 , the mounting plate 10 is provided with an electric control box 20, the electric control box 20 is provided with a PLC controller and a control panel, and the PLC controller is electrically connected with the control panel, the pressure sensor 60 and the cylinder 41.
