Description

A constant tension take-up machine

technical field

The utility model relates to the technical field of production and processing equipment, and more particularly relates to a constant tension tape take-up machine.

Background technique

After the copper strip is produced, it needs to be wound into rolls to be packaged and sold. The traditional winding method is manual winding, which has low efficiency, heavy workload, strong labor force and high labor cost. There are also automatic tape-winders on the market at present, and the tape-winders are driven by a motor to wind up the tape. Since the outer layer of copper tape will tighten the inner layer of copper tape during continuous winding, the inner layer of copper tape is too tightly attached to the winding wheel, and the whole roll of copper tape is difficult to remove.

Detailed ways

In order to achieve the purpose of full disclosure, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are only used to explain the utility model, and are not used to limit the protection scope of the utility model.

As shown in accompanying drawing 1, the structure of the constant tension take-up machine of the present utility model is shown. The constant tension take-up machine includes a frame 1, a winding wheel 2, a pulley assembly 3, a slider assembly 4, and a sensor 5.

The frame 1 includes a base portion 11 and a pole portion 12 . The reel 2 is connected with the pole part 12 of the frame 1 through the central shaft 6 . The reel 2 is connected with a driving motor (not shown), and is used to rotate around the central axis 6 at a certain speed driven by the driving motor. The pulley assembly 3 is connected with the reel 2 through a copper belt 7 . In the provided embodiment, the pulley assembly 3 includes four pulleys 31, 32, 33, 34 sequentially connected for tensioning the copper strip 7, the diameters of the four pulleys are the same, and are all smaller than the diameter of the winding wheel. The direction of rotation of two adjacent pulleys is opposite in the process of the copper strip, the direction of rotation of the pulley 31 connected with the winding wheel 2 by the copper strip 7 is opposite to the direction of rotation of the winding wheel 2, and in the four pulleys, the pulleys 31, 32, 34 is fixed by its central axis, and pulley 33 is not fixed. The slider assembly 4 includes a slider 41 and a slider frame 42 . The slider frame 42 includes two parts, a left bracket and a right bracket separated by a certain distance. The slider 41 of the slider assembly 4 is connected to the pulley 33, and the slider 41 can move up and down along the left and right brackets along with the pulley 33 under the tension of the copper strip. A sensor one 51 and a sensor two 52 are respectively arranged at a certain distance above and below the longitudinal center of the slider frame 42 on the left bracket of the slider frame 42 . The first sensor 51 and the second sensor 52 are electrically connected to the winding wheel 2, and are used to send signals to the winding wheel 2 to reduce or increase the winding speed.

In the above technical solution, the number of pulleys in the pulley assembly 3 may be two or more, and the diameters of the pulleys in the pulley assembly 3 may be the same or different.

When the copper strip 7 is taken in by the constant tension take-up machine, the copper strip 7 is guided to the pulley 33 by the pulley 34, passes through the slider 41 and winds up to the reel 2 through the pulleys 32, 31, and when the machine is running, if When the tightening reaches a certain strength, the slider 41 is lifted upwards and touches the sensor 51 above, and the sensor 51 sends a signal to the winding wheel 2 to reduce the speed of the winding wheel 2. When the tightening is less than a certain strength, the sliding block The block touches the sensor 52 below, and the sensor 52 gives a signal to the reel, causing the reel to speed up the winding speed.
