Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 4, the present embodiment provides a restraint and treatment device for a tow conduction path, which includes a mounting frame, a wheel body 7 and a stopper 9. The wheel body 7 is rotatably mounted on the mounting frame, and a wheel groove 8 for accommodating tows is formed in the wheel circumference of the wheel body 7. The limiting block 9 is fixed on the mounting plate, and the limiting block 9 stretches into the wheel groove 8 so as to limit the tows in the wheel groove 8 and prevent the tows from twisting in the wheel groove 8 through the limiting effect of the limiting block 9. The side surface of the limiting block 9 can be in sliding contact with the side wall of the wheel groove 8, and a gap can be reserved. The width of the gap (if any) should be less than the thickness of the tow to avoid the tow from backing out of the small gap. The gap between the end of the limiting block 9 and the bottom of the wheel groove 8 should be larger than the thickness of the filament bundle and smaller than the width of the filament bundle so as to prevent the filament bundle from twisting in the wheel groove 8.
In the embodiment, the tows are limited in the wheel groove 8 through the limiting block 9, and the torsion of the tows is limited, so that the problems of derailment, winding, torsion and the like of the fiber tows in the laying process are solved, and the working efficiency and quality of the tow laying are ensured.
As one possible example, in this embodiment, the mount includes a first mount layer, a second mount layer, and a connection block 10. The first installation layer and the second installation layer are all in the shape of a flat plate, the first installation layer is parallel to the second installation layer, and the connecting block 10 is fixedly connected with the first installation layer and the second installation layer respectively.
The first installation layer and the second installation layer are provided with the wheel body 7 and the limiting block 9 corresponding to the wheel body 7. The wheel body 7 and the limiting block 9 on the first installation layer are respectively a first wheel body 3 and a first limiting block (not shown in the figure), and the wheel body 7 and the limiting block 9 on the second installation layer are respectively a second wheel body 6 and a second limiting block. The first installation layer is provided with a silk passing position for the silk bundle to pass through so that the first wheel body 3 and the second wheel body 6 can wind the same silk bundle.
By making the tow pass through the tow passing position, the tow guided out by the first wheel body 3 can reach the second wheel body 6 along a straight line, and a guide roller is not required to be additionally arranged, so that the occupation of space is reduced.
As a possible example, in this embodiment, the first mounting layer comprises a first ring-shaped element 1 and a first centre element 2. The first ring member 1 has a first through hole, and the first center member 2 is disposed at a center position of the first through hole (a view along the first through hole axis). The first center piece 2 is provided with a plurality of protruding portions in the circumferential direction thereof, each protruding portion having a first protruding end and a second protruding end. The first extending end is fixedly connected with the first annular piece 1, and a gap is reserved between the second extending end and the first annular piece 1, and the gap is the threading position. The first limiting block is fixed on the first annular piece 1 and is arranged on the threading position. The first wheel body 3 is rotatably mounted on the first ring member 1. In fig. 2, only one of the first wheels 3 is shown in position. In practice, the axis of each first wheel 3 is parallel to the first mounting layer and the axis of each second wheel 6 is parallel to the second mounting layer.
As a possible example, in the present embodiment, the first center member 2 is provided with four protruding portions in the circumferential direction thereof, so that the first center member 2 is approximately cross-shaped as a whole. Correspondingly, the number of the first wheel body 3 and the first limiting block is four. Other shapes of the first central member 2 may be selected by those skilled in the art, depending on the actual needs.
As a possible example, in this embodiment, the second mounting layer comprises a second ring-shaped element 4 and a second centre element 5. The second ring member 4 has a second through hole through which the filament bundle passes, and the second center member 5 is disposed at a center position of the second through hole (a view along the second through hole axis). The second limiting block is fixed on the second central piece 5, and is arranged in a row on two sides of the second central piece 5 (the straight line of the row is parallel to the second installation layer). The second wheel body 6 is rotatably mounted on the second ring member 4.
Referring to fig. 1 and 4, the second wheel bodies 6 corresponding to the second stoppers located in the same row are parallel or approximately parallel to each other, so that the tows having larger included angles can be guided into parallel or approximately parallel tows by redirecting the tows by the second wheel bodies 6.
As a possible example, in this embodiment, the number of the two rows of second limiting blocks is at least four. The two adjacent first limiting blocks are used for limiting the tows, and the tows limited by the two second limiting blocks are respectively limited by the two second limiting blocks positioned in the center of one row of second limiting blocks.

In order to improve the deviation adjusting capability, in the embodiment, the restraint and treatment device of the tow conduction path further comprises a wire feeding roller, a wire feeding roller translation device, a laser sensor and a controller. The wire feeding roller is used for providing conveying power for the wire bundles wound on the wheel body 7, the laser sensor is used for monitoring the positions of the wire bundles and transmitting monitoring results to the controller in real time, and the controller controls the action of the wire feeding roller translation device. The godet translation device is connected with the godet and is used for correcting the deviation of the godet. By monitoring the laser sensor, the real-time deviation adjustment of the filament bundle can be realized.
