Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The belt pulley group 3 is located the upside of feed roll 2 and wind-up roll 6, and the cloth is walked around from the bottom of feed roll 2, passes through the upside of belt pulley group 3, finally winds on wind-up roll 6.

In another embodiment, the diameter of the middle of the feeding roller 2 is larger than the diameter of the two sides. When the pleated cloth passes around the feed roller 2 of this shape, both sides of the cloth are gradually spread out to both sides due to the large diameter of the middle of the feed roller 2 with respect to both sides, and the large tensile force applied to the middle of the cloth.

Referring to fig. 2 and 3, in order to flatten the folds of the fabric, in this embodiment, the machine body 1 includes a supporting frame 11, a leveling mechanism 4 is fixedly arranged on the supporting frame 11, the leveling mechanism 4 is located at the upper side of the belt pulley group 3, the leveling mechanism 4 includes two frames 41 fixedly arranged on the machine body 1, two belt pulleys 45 rotatably connected with the frames 41, a conveyor belt 44 arranged on the two belt pulleys 45, a plurality of leveling blocks 42 fixedly arranged on the conveyor belt 44, and leveling wheels 43 rotatably connected with the leveling blocks 42, the leveling blocks 42 are equidistantly distributed on the conveyor belt 44 along the transmission direction of the conveyor belt 44, the fabric passes between the belt pulley group 3 and the leveling wheels 43, the two frames 41 are in a splayed subsection, and one side of the two frames 41 close to the winding roller 6 is farther; a pressing plate 31 is arranged in the pulley group 3, and the top surface of the pressing plate 31 is in sliding connection with the bottom surface of the upper belt of the pulley group 3; the pressing plate 31 can prevent the upper layer belt of the belt wheel set 3 from being deformed by the leveling wheel 43, and at the same time, the pressing plate 31 can improve the leveling effect of the leveling wheel 43; the belt pulley 45 drives the conveyer belt 44 to run, so that the leveling wheel 43 at the bottom of the conveyer belt 44 moves to one side close to the wind-up roll 6, the leveling wheel 43 presses on cloth, the pressing plate 31 supports the upper belt of the belt pulley set 3, and the leveling wheel 43 pushes wrinkles of the cloth on the belt pulley set 3 to the edge of the cloth from the middle along the splayed direction to two sides, so that a good leveling effect is achieved.

Referring to fig. 4 and 5, the leveling block 42 is provided with a central shaft 421 for installing the leveling wheel 43, the leveling wheel 43 is in clearance fit with the central shaft 421, a contact switch 422 is arranged on one side of the central shaft 421 away from the conveyor belt 44, the contact switch 422 is electrically connected with a PLC, the frame 41 is provided with a variable speed motor for driving one of the pulleys 45 to rotate, and the PLC is electrically connected with the variable speed motor; when the cloth is leveled, a gap exists between the leveling wheel 43 positioned at the lower side of the conveyer belt 44 and the contact switch 422; when the leveling wheels 43 located at the lower side of the conveyor belt 44 are abutted against the contact switch 422, the PLC controls the variable speed motor to accelerate. When the leveling wheel 43 is positioned at the lower side of the conveying belt 44, under the condition that the cloth is not wrinkled, a gap exists between the leveling wheel 43 and the contact switch 422, when the wrinkled of the cloth moves to the lower side of the leveling wheel 43, the thickness of the cloth is large, the leveling wheel 43 is pushed to move upwards, the leveling wheel 43 is abutted to the contact switch 422, the contact switch 422 transmits a contact signal to the PLC, the PLC controls a variable speed motor on the frame 41 where the leveling wheel 43 is positioned to accelerate, the unfolding speed of the cloth is improved, and after the cloth passes, any part of the wrinkled is prevented from being unfolded. It should be noted that, when the leveling wheel 43 on the upper side abuts against the contact switch 422, the signal is not transmitted to the PLC, i.e. the PLC only collects the signal that the leveling wheel 43 on the lower side abuts against the contact switch 422, so that the rotation speed of the pulley 45 is not affected when the leveling wheel 43 on the upper side abuts against the contact switch 422.

Referring to fig. 1 and 2, in this embodiment, a press roller 5 is rotatably connected to the machine body 1, the press roller 5 is located between two frames 41, and is located at one side of the two frames 41 near the wind-up roller 6, cloth passes between the press roller 5 and the pulley set 3, and a torsion spring is disposed between the press roller 5 and the machine body 1. The wind-up roller 6 actively rotates to draw out the cloth from between the press roller 5 and the belt pulley group 3, and the tension of the cloth is improved under the action of the torsion spring; when the cloth between the press roller 5 and the wind-up roller 6 is loose, the pulling force of the wind-up roller 6 for pulling the cloth is smaller than the torsion force of the torsion spring, so that the press roller 5 cannot rotate; when cloth between the compression roller 5 and the wind-up roller 6 is tensioned, the compression roller 5 is gradually pulled to rotate under the action of friction force, at the moment, the torsion force of the torsion spring can be gradually increased, when the torsion force is balanced with the friction force of the cloth, the compression roller 5 does not rotate any more, the tension force is controlled through the torsion spring, and the cloth on the wind-up roller 6 is prevented from being too loose or too tight.

It is noted that the pulley group 3 is not provided with a motor for driving rotation, and the pulleys in the pulley group 3 and the machine body 1 are lubricated through an oil film, so that the friction force is small. The cloth is pulled by the wind-up roller 6, friction force between the cloth and the belt of the belt pulley group 3 drives the belt pulley of the belt pulley group 3 to rotate and the belt to run, so that the cloth is prevented from being wrinkled due to the fact that the speed of the cloth winding and unwinding by the belt pulley group 3 is not easy to control. The belt of the pulley group 3 is made of a material with smaller friction force, and the friction force between the cloth and the belt of the pulley group 3 is also smaller.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model 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.
