Description

Technical Field

[0001] The utility model relates to the technical field of tow production, in particular to a tow laying groove. Background Art

[0002] In the production process of tobacco, the main material in cigarette butts is two-acetate fiber tow. In the actual production process, the two-acetate fiber tow needs to be pre-processed, curled, cut, and packaged in sequence to form cigarette butts. During the pre-processing and curling processes, the two-acetate fiber tow is in a strip shape as a whole and is very soft. Starting from feeding, it first passes through a conveying structure such as pinch rolls and enters the curling machine for curling. After curling, the two-acetate fiber tow can no longer be conveyed by the pinch rolls, otherwise the curling effect of the two-acetate fiber tow will be reduced. Therefore, after the two-acetate fiber tow is output from the curling machine, it generally can only be conveyed to the laying platform by a guiding groove with a certain height difference.

[0003] Due to the limitation of the production site, the entire production line cannot be arranged in a straight line as a whole. Therefore, for the intensification of space, generally, the two-acetate fiber tow output from the coiling machine needs to be redirected during the conveying process. Currently, in order to redirect the conveying of the two-acetate fiber tow, the traditional method is to fit the entire guiding groove with the entire production line and integrally form it, which can effectively limit the conveying direction of the two-acetate fiber tow. However, the redirection of the two-acetate fiber tow completely depends on the guiding direction of the guiding groove. In this way, it is easy to cause the two-acetate fiber tow to overly rely on the guiding effect of the inner wall of the guiding groove during the conveying process. At the same time, after passing through the curling machine, the two-acetate fiber tow is in a continuous curled shape as a whole. When the two-acetate fiber tow passes through the turning point of the guiding groove, it does not match the constraint arc of the inner wall of the guiding groove, thereby reducing the smoothness of passing. Therefore, the two-acetate fiber tow is prone to wire hanging and accumulation at this place. Moreover, the properties of the two-acetate fiber tow for different types of cigarettes are different, resulting in different hardness and curling degrees of the two-acetate fiber tow, and different turning radii are required. These factors will all affect the normal conveying of the two-acetate fiber tow. Summary of the Utility Model

Among them, the frame 10 is actually a support platform for supporting and installing the shock-absorbing clamping seat 20. The main purpose of the clamping edge 11 is to facilitate the fixing of the shock-absorbing clamping seat 20.

[0027] It should be noted that the steering groove member 30 is integrally formed by a metal plate or plastic as a whole. It has a certain torsion in space as a whole to adapt to the steering in space. In the above-mentioned embodiment, a ring groove 12 is arranged on the frame 10, and the ring groove 12 and the peripheral edge of the frame 10 form the clamping edge 11. Such a setting enables the staff to adjust the installation position of the shock-absorbing clamping seat 20 according to the actual situation, improving the adaptability.

[0028] This tow laying groove adopts a detachable structural design, which is convenient for later replacement and maintenance.
