Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings.
In the following embodiments, the directions are described with reference to the directions of the front view of the variable pressure take-up pinch roller device in fig. 1, that is, the up-down directions refer to the up-down directions in fig. 1, respectively, and the left-right directions refer to the left-right directions in fig. 1, respectively.
< example one >
Fig. 1 is a schematic structural diagram of a variable-pressure take-up pinch roller device according to a first embodiment of the invention.
As shown in fig. 1, the present embodiment provides a variable pressure take-up pinch roller device 100, which is installed between a processing device and a winding device, and is used for controlling the tension of a cable 200 when the winding device winds, and the variable pressure take-up pinch roller device includes a bracket 1, a connecting mechanism 2, a pinch roller 3, a cylinder 4, and a counterweight mechanism 5.
The cable 200 extends from the processing device towards the spooling device. The winding device continuously pulls out the cable 200 from the processing device by rotation and winds it. The right side of the cable 200 in fig. 1 extends from the processing device and the left side of the cable 200 is wound by the winding device.
The bracket 1 is fixed on the ground between the processing device and the winding device.
The link mechanism 2 is rotatably mounted on the stand 1, and includes a rotating shaft 21, a first link 22, and a second link 23.
The rotating shaft 21 is rotatably mounted on the stand 1.
One end of the first link 22 is fixedly connected to the rotating shaft 21, and the length direction of the first link is perpendicular to the axial direction of the rotating shaft 21, so that the first link can rotate along with the rotating shaft 21.
One end of the second link 23 is fixedly connected to the rotating shaft 21, and is located on the same side of the rotating shaft 21 as the first link 22, and the length direction of the second link is perpendicular to the axial direction of the rotating shaft 21, and can rotate along with the rotating shaft 21.
The wire pressing wheel 3 is rotatably installed on one side of the first link 22 away from the rotating shaft 21, is arranged between the processing device and the winding device, presses the cable 200 to be wound and controls the tension of the cable 200. In this embodiment, the cable 200 is located below the wire pressing wheel 3, and the wire pressing wheel 3 moves downwards to increase the tension of the cable 200, and moves upwards to decrease the tension of the cable 200.
The cylinder 4 has a push rod 41, and the push rod 41 is fixedly connected with a section of the second connecting rod 23 away from the rotating shaft 21. By setting different air pressures for the air cylinder 4, the force provided by the push rod 41 to the second connecting rod 23 is changed, so that the pressing force of the wire pressing wheel 3 on the cable 200 is changed, and the tension of the cable 200 is changed.
The counterweight mechanism 5 is fixedly installed on the rotating shaft, is located on one side far away from the first connecting rod, and is provided with a counterweight rod 51 and a counterweight block 52.
One section of the weight lever 51 is fixedly connected to the rotating shaft 21 and is located on the side away from the first connecting rod 22. In this embodiment, the weight lever 51 is a threaded rod having scales corresponding to the cables 200 of different specifications.
The weight 52 is provided at a predetermined position of the weight lever 51 for providing a pressure of the wire guide to press the cable 200. In this embodiment, the weight 52 has a threaded bore through which it is rotatably received on the threaded rod. Rotating the counterweight 52 causes it to move on the threaded rod, which can change the moment of the counterweight relative to the shaft 21, causing the pressure with which the creasing roller 3 compresses the cable 200 to change, thus changing the tension of the cable 200.
For cables 200 of different specifications, the counterweight block 52 needs to be moved to the position of the corresponding scale on the counterweight rod 51, so that the tension of the cable 200 meets the requirement of winding of the winding device.
The process of controlling the tension of the cable 200 by the variable-pressure take-up pinch roller device of the embodiment is as follows:
the air pressure of the air cylinder 4 is set, and at this time, the push rod 41 provides a downward pulling force to the second link 23 located at one side of the rotation shaft 21, so that the wire wheel mounted on the first link 22 receives a downward force, and the weight 52 located at the other side of the rotation shaft 21 provides a downward pulling force to the weight lever 51, so that the wire wheel mounted on the first link 22 receives an upward force.
When the air pressure of the air cylinder 4 is fixed, the scale position of the cable 200 produced by the generation device on the balance weight rod 51 is determined according to the specification of the cable 200, and the balance weight block 52 is moved to the corresponding scale position on the balance weight rod 51, so that the pressure of the wire pressing wheel 3 pressing the cable 200 and the tension of the cable 200 are changed, and the tension of the cable 200 meets the winding requirement of the winding device.
When the position of the counterweight block 52 on the counterweight sensor 51 is fixed, the downward pulling force provided by the push rod 41 to the second connecting rod 23 on the side of the rotating shaft 21 is adjusted by changing the air pressure of the air cylinder 4, so that the pressure of the wire pressing wheel mounted on the first connecting rod 22 to the cable 200 and the tension of the cable 200 can be changed, and the wire pressing wheel mounted on the first connecting rod 22 is subjected to an upward force.
When the processing device produces the cable 200 with a small size, because the tension limit that the small-size cable 200 can bear is small, even if the air pressure of the air cylinder 4 is set to be the lowest, the pressure of the wire pressing wheel 3 on the cable 200 can still be too large, and the cable 200 is broken due to the too large tension. At this time, the pressure of the wire guide wheel 3 needs to be finely adjusted by moving the weight 52 on the weight lever 51.

Fig. 2 is a schematic structural diagram of a variable-pressure take-up pinch roller device according to a second embodiment of the invention. Fig. 3 is a schematic structural view of a weight according to a second embodiment of the present invention.
As shown in fig. 2-3, the second embodiment provides a variable pressure take-up roller device 100 for changing the tension of a cable 200 by using a fitting part 511 and a weight 521. Compared with the first embodiment, the difference is that the weight rod 51 has the attaching portion 511, and the weight 52 is a plurality of weights 521, which are specifically distinguished as follows:
in the present embodiment, the attaching portion 511 is a square baffle plate provided in the longitudinal direction of the weight 51. The weight 52 is a weight 521 of different weight set according to the specification of the cable 200 to be produced. The weight 521 is a cylindrical structure, and has a bayonet having a width equal to the diameter of the weight rod 51, and the weight 521 can be clamped on the weight rod 51 through the bayonet.
In this embodiment, the process of adjusting the tension of the cable 200 by using the weight mechanism 5 is as follows:
the weight 521 corresponding to the weight is selected according to the specification of the produced cable 200.
The bayonet of the weight 521 is engaged with the weight lever 51, and the end surface of the weight 521 on one side is engaged with the engaging portion 511, so that the pressure of the wire guide 3 on the cable 200 is reduced by the lever principle, thereby reducing the tension of the cable 200.
