Description

Technical Field

[0001] The utility model relates to a device for adjusting the take-up speed of an aluminum busbar. Background Art

[0002] In the production process of high-conductivity aluminum busbars, after one end of the aluminum busbar is produced and output by the front-end extruder, the strip is fed forward during the startup process, and the other end of the aluminum busbar is wound up by the winding device, and the rotation and winding speed of the winding device is given by an encoder pressed on the guide wheel in the middle of the production line. However, due to the relatively smooth surface of the aluminum busbar, there is a certain deviation in the speed measurement, resulting in inconsistent speeds of the front and rear strips. There will be too much strip accumulation and sag, scraping the equipment, or the front and rear strips will be tightened and slip, or the aluminum busbar will be stretched and the thickness will deviate, resulting in unqualified products. Utility Model Content

[0003] The utility model improves the above-mentioned problem, that is, the technical problem to be solved by the utility model is to provide a device for adjusting the take-up speed of the aluminum busbar, which has a simple structure and is easy to use. By converting the swing angle of the second guide wheel and the swing arm into the resistance value change of the potentiometer, the problem of inconsistent speed of the front and rear strips is solved, thereby improving product quality.

[0004] The utility model is constructed as follows: it includes a base and a first guide wheel arranged on the upper side of the base, a swingable swing arm is arranged in the middle of the base, a second guide wheel is arranged on the side of the swing arm away from the first guide wheel, the aluminum busbar is guided and transported through the first guide wheel and the second guide wheel, a linkage gear is arranged at the rear of the other side of the swing arm, a potentiometer is arranged below the linkage gear, and the potentiometer gear of the potentiometer is meshed with the linkage gear.

[0005] Furthermore, a cylinder is arranged above the swing arm, the upper end of the cylinder is connected to the base, and the lower end of the cylinder is connected to the swing arm.

[0006] Furthermore, a side of the swing arm close to the first material guide is connected to the linkage gear via a fixed shaft, and the fixed shaft passes through the base and rotates with the base.

[0007] Furthermore, U-shaped grooves are arranged on the outer peripheries of the first guide wheel and the second guide wheel.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the device has a simple structure, reasonable design and is easy to use. When the front end extruder of the equipment conveys the aluminum mother strip forward, and the winding device at the rear end is driven by a motor to wind up the aluminum mother strip of the production number, if there is a speed difference between the winding device and the rolling speed of the equipment, the second guide wheel will swing up and down to adapt to the adjustment. In the process of the second guide wheel swinging up and down, the swing of the swing arm drives the linkage gear behind the swing arm to rotate, and the linkage gear drives the gear of the potentiometer to rotate, thereby adjusting the resistance value of the potentiometer. The change in the resistance value of the potentiometer will be transmitted to the controller of the equipment, thereby adjusting the winding speed of the winding device, so that the winding device matches the rolling speed of the equipment, thereby avoiding the problem of inconsistent speeds of the front and rear strips, preventing the accumulation of too much strip and drooping to scrape the equipment, or the front and rear strips are tightened and slip, or the aluminum mother bar is stretched and the thickness deviation is large and unqualified.

[0010] Figure 2 The structure of the embodiment of the utility model is shown in FIG. Figure 2 . DETAILED DESCRIPTION

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0012] Example: Figure 1~2 As shown, in this embodiment, a device for adjusting the winding speed of the aluminum busbar is provided, including a base 5 and a first guide wheel 1 arranged on the upper side of the base, a swingable swing arm 4 is arranged in the middle of the base, a second guide wheel 2 is arranged on the side of the swing arm away from the first guide wheel, the second guide wheel is pressed against the surface of the aluminum busbar 9, and the aluminum busbar is guided and transported through the upper surface of the first guide wheel and the lower surface of the second guide wheel, a linkage gear 6 is arranged at the rear of the other side of the swing arm, a potentiometer 8 is arranged below the linkage gear, and the potentiometer gear 7 of the potentiometer is meshed with the linkage gear.

[0013] The base is in an inverted U shape.

[0014] The above-mentioned first guide wheel and second guide wheel are used to limit the conveying direction of the aluminum busbar so that the aluminum busbar 9 remains on the center line; the first guide wheel and the second guide wheel themselves are both rotatable, the first guide wheel is installed on the base, and the second guide wheel is installed on the swing arm. During the production process, if the speed difference between the aluminum busbar winding device and the equipment rolling the aluminum busbar changes, the second guide wheel will swing up and down to adjust and adapt.

[0015] In the embodiment of the utility model, a cylinder 3 is arranged above the swing arm, the non-working end of the cylinder is hinged to the base, and the working end of the cylinder is hinged to the middle part of the swing arm.

[0016] A cylinder is installed in the middle of the swing arm connected to the second guide wheel, and the cylinder base is installed on the base to apply a certain pressure to the second guide wheel so that it is pressed tightly against the aluminum busbar, so that the aluminum busbar will not fall out of the U-shaped groove of the second guide wheel during the swinging process.

[0017] In an embodiment of the utility model, the side of the swing arm close to the first material guide is connected to the linkage gear via a fixed shaft, and the fixed shaft passes through the base and rotates with the base.

[0018] In the embodiment of the utility model, U-shaped grooves are arranged on the outer circumferences of the first guide wheel and the second guide wheel.

[0019] In the embodiment of the utility model, when working: the front end extruder of the equipment conveys the aluminum busbar strip forward, and the winding device at the rear end is driven by a motor to wind up the aluminum busbar of the production number. If there is a speed difference between the winding device and the rolling speed of the equipment, the second guide wheel will swing up and down to adapt and adjust. In the process of the second guide wheel swinging up and down, the swing of the swing arm drives the linkage gear to rotate, and the linkage gear drives the gear of the potentiometer to rotate, thereby adjusting the resistance value of the potentiometer. The change in the resistance value of the potentiometer will be transmitted to the controller of the equipment, thereby adjusting the winding speed of the winding device to match the rolling speed of the winding device with the equipment, thereby avoiding the problem of inconsistent speeds of the front and rear strips, preventing the accumulation of too much strip and sagging to scrape the equipment, or preventing the front and rear strips from slipping due to tension, or the problem of large thickness deviation of the stretched aluminum busbar being unqualified.

[0020] The utility model converts the swing angle into a resistance value, and adjusts the wire-reeling speed of the winding device through the feedback resistance value change in the program, so that the wire-reeling device matches the rolling speed.
