Further, be provided with vertical slot hole in the main part frame, the back fixed mounting of main part frame has vertical guide rail, and fixed mounting has elevator motor on the base, and wherein, one side of vertical guide rail is equipped with vertical setting and by elevator motor driven hold-in range, installs the slider on the vertical guide rail, and fixed mounting has the clamp splice of pressing from both sides tight hold-in range on the slider, and the axle core of adjusting drum passes the slot hole and rotates with the slider to be connected.

Furthermore, a rotating shaft of the lifting motor is connected with a magnetic powder clutch through belt transmission and drives the synchronous belt through the magnetic powder clutch.

Furthermore, photoelectric sensors which are respectively arranged at two ends of the long hole and are triggered by the sliding block are arranged on the back surface of the main body frame.

Furthermore, the base is fixedly provided with an unreeling motor for driving the unreeling roller to rotate.

Compared with the prior art, the utility model discloses the beneficial effect who gains does: the utility model discloses a but the adjusting cylinder of vertical lift, the rate of tension in automatic adaptation material area, when the material area was too loose, adjusting cylinder pushed down and made the material area taut, guaranteed the conveying precision in material area.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, a counterweight tensioning mechanism of an unreeling machine includes a base 1, a main body frame 2 and an unreeling roller 3 rotatably mounted on the main body frame 2, a reversing roller 4 parallel to the unreeling roller 3 is rotatably mounted on the top of the main body frame 2, and an adjusting roller 5 capable of axially rotating and vertically lifting is mounted on the main body frame 2. The utility model discloses a but adjusting cylinder 5 of vertical lift, the rate of tension in automatic adaptation material area, when the material area was too loose, the material area was taut when adjusting cylinder 5 pushed down, guaranteed the conveying precision in material area.

Further, be provided with vertical slot hole 6 on the main part frame 2, the back fixed mounting of main part frame 2 has vertical guide rail 7, and fixed mounting has elevator motor 8 on the base 1, and wherein, one side of vertical guide rail 7 is equipped with vertical setting and by elevator motor 8 driven hold-in range 9, installs slider 10 on the vertical guide rail 7, and fixed mounting has the clamp splice 11 of pressing from both sides tight hold-in range 9 on the slider 10, and the axle core of adjusting drum 5 passes slot hole 6 and rotates with slider 10 to be connected. Lifting motor 8 drive adjusting cylinder 5 goes up and down, cooperates pull force detection device, tensile proportion detection device etc. to realize the initiative regulation of adjusting cylinder 5 height, avoids the material area tension and the fracture appears.

Further, a rotating shaft of the lifting motor 8 is connected with a magnetic powder clutch 12 through belt transmission and drives the synchronous belt 9 through the magnetic powder clutch 12. The lifting motor 8 is driven synchronously through the magnetic powder clutch 12, and can only output within a specific power range due to the limitation of the adsorption force of the magnetic powder clutch 12, and the adjusting roller 5 is difficult to continuously descend when the tension degree of the material belt is higher, so that the tension degree of the material belt can be controlled within a preset range by utilizing the limitation of the adsorption force of the magnetic powder clutch 12.

Further, photoelectric sensors 13 which are respectively arranged at two ends of the long hole 6 and are triggered by the slide blocks 10 are arranged on the back surface of the main body frame 2.

Further, an unwinding motor 14 for driving the unwinding roller 3 to rotate is fixedly mounted on the base 1. The unwinding motor 14 drives the unwinding roller 3 to rotate, and only the rotating speed of the unwinding motor 14 needs to be controlled, so that the friction force between the unwinding roller 3 and the material belt is converted into the traction force for the material belt, and the material belt is tensioned.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
