Description

Technical Field

[0001] The utility model relates to the technical field of tensioners, in particular to a double-cylinder tensioner. Background Technique

[0002] In modern industrial production, especially in industries such as wire and cable, textile fibers, and precision mechanical part processing, the application of electronic tensioners is crucial. These devices ensure the stability and product quality in the production process by precisely controlling the tension of materials. However, with the continuous progress of production technology and the increasing diversification of product requirements, traditional tensioners are unable to cope with complex process requirements, especially on production lines that require frequent station conversions.

[0003] Previously, we applied for an electronic tensioner with a quick tension switching device (CN214934933U). In the technical content of this tensioner, a single cylinder was used to adjust the tension. When adjusting the tension with a single cylinder, due to different process requirements during winding, for some products, when the winding station is converted, the tensioner needs to provide a certain amount of surplus wire to ensure that the wire does not break during the station conversion. Therefore, we have re-proposed a double-cylinder tensioner. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a double-cylinder tensioner, which solves the problems raised in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A double-cylinder tensioner includes a bearing substrate. Vertically tensioning wheels and horizontally tensioning wheels are respectively rotatably arranged on the front surface of the bearing substrate. Vertically tensioning drive modules and horizontally tensioning drive modules are respectively installed on the back surface of the bearing substrate. Vertically adjusting grooves and horizontally adjusting grooves are respectively formed inside the bearing substrate. The drive ends of the vertically tensioning drive modules and the horizontally tensioning drive modules respectively extend to the front surface of the bearing substrate through the vertically adjusting grooves and the horizontally adjusting grooves, and are correspondingly connected to the vertically tensioning wheels and the horizontally tensioning wheels.

[0006] Further, a tension sensing wheel and a double-groove tension wheel are respectively rotatably connected to the front surface of the bearing substrate. A gravity sensor and a brake are respectively installed on the back surface of the bearing substrate. The detection end of the gravity sensor is connected to the tension sensing wheel, and the braking end of the brake is connected to the double-groove tension wheel.

[0007] Further, several wire passing wheels are rotatably connected between the vertically tensioning wheels, the horizontally tensioning wheels, the tension sensing wheel, and the double-groove tension wheel on the front surface of the bearing substrate. An inlet device is installed at the bottom of the front surface of the bearing substrate. Both sides of the bottom of the bearing substrate are connected with feet.

[0008] Further, a circuit control board and an equipment box are respectively installed on the back surface of the bearing substrate, and the equipment box covers the gravity sensor, the brake, and the circuit control board.

[0009] Further, a touch screen is installed on one side of the equipment box, and a plurality of power supplies and communication connectors are installed on the other side.

[0010] Further, the vertical tensioning drive module includes a base and a vertical drive cylinder installed on the back surface of the bearing substrate. Guide rods are connected between the bases. Springs and lifting seats are respectively arranged outside the guide rods. The springs abut between the bases and the lifting seats. The telescopic end of the vertical drive cylinder is connected to the lifting seat, and the lifting seat is connected to the vertical tensioning wheel.

[0011] Further, the horizontal tensioning drive module includes a horizontal drive cylinder installed on the back surface of the bearing substrate. A linkage is installed at the telescopic end of the horizontal drive cylinder, and the linkage is connected to the horizontal tensioning wheel.

[0012] The present utility model provides a double-cylinder tensioner. Compared with the prior art, it has the following beneficial effects:

[0013] For this tensioner, double-cylinder adjustment is adopted. The advantage of using double cylinders to adjust the wire tension compared with single-cylinder adjustment is that the double-cylinder adjustment has a wider radiation range and can also provide a certain amount of surplus wire to ensure that the wire will not break during the station conversion, so as to meet the requirements of different winding processes.

[0023] 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 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.

[0024] Please refer to Figure 1-8 , the present utility model provides a technical solution: a double-cylinder tensioner, which is composed of a bearing substrate 1, a vertical tensioning wheel 2, a horizontal tensioning wheel 3, a tension induction wheel 4, a double-groove tensioning wheel 5, a plurality of wire passing wheels 6, a vertical tensioning drive module 7, a horizontal tensioning drive module 8, a gravity sensor 9, a brake 10, a circuit control board 11 and an equipment box 12. Among them, the vertical tensioning wheel 2, the horizontal tensioning wheel 3, the tension induction wheel 4, the double-groove tensioning wheel 5, and the plurality of wire passing wheels 6 are all rotatably connected to the front surface of the bearing substrate 1, and the vertical tensioning drive module 7, the horizontal tensioning drive module 8, the gravity sensor 9, the brake 10, the circuit control board 11 and the equipment box 12 are all installed on the back surface of the bearing substrate 1. For the convenience of installation, feet 101 are connected to both sides of the bottom of the bearing substrate 1. In addition, a vertical adjustment groove 102 and a horizontal adjustment groove 103 are respectively opened inside the bearing substrate 1. After the drive ends of the vertical tensioning drive module 7 and the horizontal tensioning drive module 8 pass through the inside of the vertical adjustment groove 102 and the horizontal adjustment groove 103, they are connected to the vertical tensioning wheel 2 and the horizontal tensioning wheel 3. The detection end of the gravity sensor 9 is connected to the tension induction wheel 4, and the braking end of the brake 10 is connected to the double-groove tensioning wheel 5;

[0025] The equipment box 12 covers the outside of the gravity sensor 9, the brake 10, and the circuit control board 11. A touch screen 121 is installed on one side of the equipment box 12, and a plurality of communication connectors 122 are installed on the other side, which is convenient for control box communication;

[0026] The vertical tension driving module 7 includes a base 71 installed on the back surface of the bearing substrate 1 and a vertical driving cylinder 75. A guide rod 72 is connected between the bases 71. Springs 73 and lifting seats 74 are respectively arranged on the outer part of the guide rod 72. The spring 73 abuts between the base 71 and the lifting seat 74. The telescopic end of the vertical driving cylinder 75 is connected to the lifting seat 74, and the lifting seat 74 is connected to the vertical tension pulley 2.

[0027] The horizontal tension driving module 8 includes a horizontal driving cylinder 81 installed on the back surface of the bearing substrate 1. A linkage 82 is installed at the telescopic end of the horizontal driving cylinder 81, and the linkage 82 is rotatably connected to the horizontal tension pulley 3.

[0028] It should be noted that: both between the lifting seat 74 and the vertical tension pulley 2 and between the linkage 82 and the horizontal tension pulley 3 are rigid connections. Bearings are installed in the middle of both the vertical tension pulley 2 and the horizontal tension pulley 3. Both the vertical tension pulley 2 and the horizontal tension pulley 3 can rotate around the middle axis core (screw) through the bearings. Therefore, even with rigid connections, it does not affect the relative rotation between the lifting seat 74, the linkage 82 and the vertical tension pulley 2, the horizontal tension pulley 3 respectively.

[0029] After the wire is wound around the outside of the vertical tension pulley 2, the horizontal tension pulley 3, the tension induction pulley 4, the double-groove tension pulley 5, and several wire passing pulleys 6, the vertical tension driving module 7 drives the vertical tension pulley 2 to move along the vertical adjustment groove 102, so as to be able to perform tension adjustment processing on the tightness of the wire. Similarly, the horizontal tension driving module 8 drives the horizontal tension pulley 3 to move along the horizontal adjustment groove 103, and can also perform tension adjustment processing on the tightness of the wire. Since both the vertical tension driving module 7 and the horizontal tension driving module 8 use cylinders as the power source, a double-cylinder tensioner is formed. And during the adjustment process, the gravity sensor 9 can monitor the wire tension.
