Abstract
The utility model discloses a yarn surface tightening roller adjusting device, which comprises a tightening roller, a tightening device and a tightening device fixing frame used for fixing the tightening device. A rotating shaft of the tightening roller is arranged in a bearing on a bearing block; the end part of the tightening device is connected with the bearing block; two ends of the rotating shaft of the tightening roller are provided with a guide bearing respectively; the guide bearing is arranged in a guide slot on a guide block; and the guide block is fixed on the tightening device fixing frame. The yarn surface tightening roller adjusting device has the advantage of preventing a cylinder from being damaged due to the gravity of the tightening roller.
Description
Technical field
The utility model relates to technical field of textile machine, particularly a kind of regulating mechanism that is used for the holding device that unwinding device holds out against the felt-cloth face.
Background technology
At present, existing yarn face holding device employing holds out against roller the felt-cloth face is held out against, adopt cylinder control to hold out against the flexible of roller, the push rod front end adapter shaft bearing of cylinder is provided with bearing in the bearing seat, the rotating shaft that holds out against roller is arranged in this bearing, the weight that holds out against roller is born by the push rod of cylinder, holds out against in the process holding out against roller, because it is longer to hold out against the length of roller, so hold out against the effect that can be subjected to uneven power in the roller telescopic process in cylinder push-rod control, cylinder damaged.
Summary of the invention
The purpose of this utility model is to provide a kind of yarn face to hold out against roller regulating device at the problem that causes cylinder to damage easily of the existing yarn face holding device existence described in the background technology.
The realization the technical solution of the utility model is as follows:
A kind of yarn face holds out against roller regulating device, it comprises the holding device fixed mount that holds out against roller, holding device and be used for fixing holding device, the described rotating shaft that holds out against roller is arranged in the bearing on the bearing seat, the end of described holding device is connected with this bearing seat, the rotating shaft two ends that hold out against roller are provided with center bearing pilot bearing, this center bearing pilot bearing is arranged in the guide groove on the orienting lug, and orienting lug is fixed on the holding device fixed mount.
Described holding device is a cylinder.
The beneficial effects of the utility model are because yarn face of the present utility model holds out against the roller regulating mechanism and is provided with center bearing pilot bearing at the rotating shaft two ends that hold out against roller, center bearing pilot bearing is arranged on the orienting lug, orienting lug is arranged on the holding device fixed mount, therefore, the weight that holds out against roller mainly is to be born by orienting lug and center bearing pilot bearing, and transfer on the holding device fixed mount, cylinder can't bear the weight that holds out against roller, avoided the damage of the cylinder that causes because be subjected to holding out against the roller gravity effect like this, prolong the service life of cylinder, reduced the expense of safeguarding.
Description of drawings
Fig. 1 is a scheme drawing of the present utility model;
Among the figure, 1 for holding out against roller, and 2 is cylinder, and 3 is the holding device fixed mount, and 4 is center bearing pilot bearing, and 5 is orienting lug, and 6 is bearing seat, and 7 is bearing.
The specific embodiment
Hold out against roller regulating device with reference to a kind of yarn face shown in Figure 1, it comprises and holds out against roller 1, holding device and the holding device fixed mount 3 that is used for fixing holding device, holding device is generally selected cylinder 2 for use, holding device fixed mount 3 is generally selected the let off roll mounting bracket for use, cylinder 2 is fixed on the let off roll mounting bracket, the described rotating shaft that holds out against roller 1 is arranged in the bearing 7 on the bearing seat 6, the end of the push rod of described cylinder 2 is connected with this bearing seat 6, the rotating shaft two ends that hold out against roller 1 are provided with center bearing pilot bearing 4, this center bearing pilot bearing 4 is arranged on the orienting lug 5, this center bearing pilot bearing 4 is arranged in the guide groove on the orienting lug 5, and orienting lug 5 is fixed on the let off roll mounting bracket.In working order down, the push rod of cylinder 2 is released, drive holds out against roller 1 and withstands on the let off roll, the felt-cloth face can be held out against, make cloth cover smooth, the gravity that holds out against roller 1 is mainly transferred on the orienting lug 5 by center bearing pilot bearing 4, orienting lug 5 is provided with guide groove, therefore can be so that the rolling of center bearing pilot bearing 4, and orienting lug 5 is fixed on the let off roll mounting bracket, therefore, the push rod of cylinder 2 does not bear the gravity that holds out against roller 1, and the gravity that holds out against roller 1 is mainly born by the let off roll mounting bracket, passes through this set, can prolong the period of service of cylinder 2, reduce the maintenance cost that the yarn face holds out against roller 1 control apparatus.
Claims (2)
1. a yarn face holds out against roller regulating device, it comprises the holding device fixed mount that holds out against roller, holding device and be used for fixing holding device, it is characterized in that: the described rotating shaft that holds out against roller is arranged in the bearing on the bearing seat, the end of described holding device is connected with this bearing seat, the rotating shaft two ends that hold out against roller are provided with center bearing pilot bearing, this center bearing pilot bearing is arranged in the guide groove on the orienting lug, and orienting lug is fixed on the holding device fixed mount.
2. yarn face according to claim 1 holds out against roller regulating device, it is characterized in that: described holding device is a cylinder.
