Technical Field

[0001] This utility model relates to the field of constant tension control technology, specifically to a hydraulic cylinder constant tension control device. Background Technology

[0002] In the production of paper tubes, the paper tubes need to be fed out of the winding mold by a belt. At the same time, in order to improve the quality of the paper tubes, the belt needs to maintain a constant tension. Currently, most of them use the screw adjustment method, which has the disadvantages of inconvenient adjustment, inaccuracy and instability. Utility Model Content

[0003] The purpose of this invention is to provide a hydraulic cylinder constant tension control device, which solves the problems of inconvenient, inaccurate and unstable adjustment that most existing hydraulic cylinder constant tension control devices currently use screw adjustment.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution: The present invention includes: a frame, on one side of the frame are two symmetrically distributed cantilever tension sensors, and on one side of the frame is a hydraulic cylinder, which is located between the two cantilever tension sensors.

[0005] Preferably, one end of each of the two cantilever tension sensors is fixed to one side of the frame, and the other end of each of the two cantilever tension sensors is provided with a protective bolt.

[0006] Preferably, a swing joint is provided between the two cantilevered tension sensors.

[0007] Preferably, the two ends of the swing joint are respectively mounted on two cantilever tension sensors.

[0008] Preferably, the swing joint is located between the frame and the hydraulic cylinder.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] By adding two symmetrical cantilever force sensors to the hydraulic cylinder, the load force is detected in real time when the hydraulic cylinder is loaded, and the detected result is fed back to the control system. The control system will control the hydraulic cylinder to reduce or increase the tension, thereby achieving the effect of timely control of constant tension in the hydraulic cylinder, making the constant tension adjustment of the hydraulic cylinder convenient, accurate and stable.

[0015] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0016] This embodiment provides a technical solution: a hydraulic cylinder constant tension control device, such as... Figure 1-2 As shown, the device includes a frame 1 and a swing joint 5. Two symmetrically distributed cantilever tension sensors 2 are installed on one side of the frame 1. One end of each cantilever tension sensor 2 is fixed to one side of the frame 1, and the other end of each cantilever tension sensor 2 is provided with a protective bolt 4 to prevent excessive tension from damaging the cantilever tension sensor 2. A hydraulic cylinder 3 is installed on one side of the frame 1 and between the two cantilever tension sensors 2. One end of the telescopic rod of the hydraulic cylinder 3 extends to the other side of the frame 1. The swing joint 5 is located between the two cantilever tension sensors 2, with both ends of the swing joint 5 respectively installed on the two cantilever tension sensors 2. The swing joint 5 is located between the frame 1 and the hydraulic cylinder 3.

[0017] In use: One end of the telescopic rod of hydraulic cylinder 3 is connected to the load. The tension of the load is controlled by controlling the pulling force of hydraulic cylinder 3 to keep it constant. When the load pulling force of hydraulic cylinder 3 increases, the cantilever tension sensor 2 detects the real-time tension and feeds the detection result back to the control system. The control system will control hydraulic cylinder 3 to reduce the pulling force. When the load pulling force of hydraulic cylinder 3 decreases, the cantilever tension sensor 2 detects the real-time tension and feeds the detection result back to the control system. In this way, hydraulic cylinder 3 can be controlled to increase the pulling force in a timely manner to achieve the effect of controlling hydraulic cylinder 3 to maintain constant tension.

[0018] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
