There are sliders on the inner wall of the limiting ring, and the sliders are placed in the corresponding spiral grooves, so that when the first and second limiting rollers rotate with the rotating power machine as required, the first and second limiting rollers The two limit rings on the roller will move synchronously along the corresponding first and second limit rollers under the cooperation of the slider and the corresponding spiral groove, so as to realize the distance adjustment between the two limit rings and adapt to different Limit requirements for width strips.

A positioning mechanism is arranged on the first and second limiting rollers, and the positioning mechanism includes two positioning rods respectively screwed on the bearings with seats connecting the first and second limiting rollers, and the two positioning rods are respectively locked. It is connected to the groove corresponding to the outer circle of the limit ring, and a positioning block is set on the two positioning rods, so that when the limit rings on the first and second limit rollers are adjusted in place, the two The positioning rod with positioning block is screwed on the bearing with seat, and snapped into the groove corresponding to the outer circle of the limit ring, so that the positioning block restricts the movement of the limit ring, and then completes the positioning of the limit ring, so that the limit The ring no longer moves.

The common ends of the first and second limit rollers pass through the corresponding bearings with seats and are connected to the corresponding drive wheels respectively, the two drive wheels are connected through the transmission mechanism belt, and the second limit roller is connected with the rotating power machine, so that Driven by the rotating power machine, the first and second limiting rollers are rotated through the transmission belt and the pulley.

The utility model has the following advantages and effects: adopting the above scheme, when the first and second limiting rollers can be rotated with the rotating power machine according to the needs, the two limiting rings on the first and second limiting rollers will be Under the cooperation of the slider and the corresponding spiral groove, it moves synchronously along the corresponding first and second limit rollers to realize the adjustment of the distance between the two limit rings, adapting to the limit requirements of strips of different widths, and has a simple structure , The adjustment is convenient and fast. After adjustment, the two limit rings will not move through the positioning mechanism. It has the advantages of flexible limit adjustment, high limit reliability and stability.

Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application are clearly and completely described below in conjunction with the accompanying drawings.

The limit device for strip correction provided by the utility model includes the first and second limit rollers 31 and 32 arranged side by side, which are used for synchronously limiting the new and old strips a11 and a21 before splicing without glue, As shown in Figure 1 and Figure 4, the longitudinal misalignment of the new and old strips a11 and a21 in the splicing section shall be controlled within the range of ±0.5mm;

The common ends of the first limiting roller 31 and the second limiting roller 32 pass through the corresponding belt seat bearings 38 to be connected with the corresponding pulleys respectively, and the two pulleys are connected by a transmission belt 37 to complete the transmission. 32 links to each other with rotary power machine 36, so that under the drive of rotary power machine 36, the first and second limit rollers 31, 32 are rotated by transmission belt 37 and pulley; An axial adjustment mechanism is provided, and the axial adjustment mechanism includes spiral grooves 33 with opposite helical directions respectively arranged on the roller surfaces at both ends of the first and second limit rollers 31 and 32, respectively sleeved on the first and second limit rollers. The limit rings 34 at the two ends of the position rollers 31, 32 are provided with slide blocks 341 on the inner circular wall of each limit ring 34, and the slide blocks 341 are placed in the corresponding spiral grooves 33 so that when the first and second limit rings When the position rollers 31,32 rotate with the rotary power machine 36, the two spacer rings 34 on the first and second spacer rollers 31,32 will all move synchronously along The corresponding first and second limit rollers 31, 32 move to realize the distance adjustment between the two limit rings 34, adapting to the limit of different strips, as shown in Figure 1, so that the new and old strips a11, a21 Both are limited in the two limit rings 34, which are suitable for the limit requirements of strips of different widths; a positioning mechanism is set on the first limit roller 31 and the second limit roller 32, and the positioning mechanism includes screw connection respectively. 1.
