Description
Technical field
The utility model relates to a kind of automatic tension-adjusting device, especially a kind of automatic tension-adjusting device of warping machines.
Background technology
Warping is the preparatory process before the crucial weaving, and warping tension force directly has influence on the smooth of warp knitting cloth face, therefore must guarantee the yarn tension basically identical on each coiled hair on the same shuttle.So, people develop various warping machines tension controllers, as Chinese patent ZL91229567.8, the warping machines tension controller of ZL94247535.9 and ZL972473 79.3, all belong to mechanical type single yarn tension controller, they will change the full wafer yarn tension must regulate respectively one by one, extremely inconvenience, and can be because the artificial origin regulates not in place.In addition, this type of tension controller adjustable range is limited, can not thoroughly compensate because the tension variation of the descending process of yarn bobbin.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of easy to adjust, the precision height thoroughly compensates the warping machines automatic tension-adjusting device of tension variation in the descending process of yarn bobbin.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of automatic tension-adjusting device, comprise support, described support is provided with top roller, described top roller is connected with support by the top roller axle, also be provided with swing arm on the described support around the rotation of top roller axle, described swing arm is provided with bottom roll, described bottom roll flexibly connects by bottom roll axle and swing arm, described automatic tension-adjusting device also comprises swing arm driving mechanism, and described swing arm driving mechanism can drive described swing arm and rotate around described top roller axle.
According to another embodiment of the present utility model, automatic tension-adjusting device comprises that further described swing arm driving mechanism can realize by motor.
According to another embodiment of the present utility model, automatic tension-adjusting device comprises that further described swing arm driving mechanism is connected by gear with described swing arm.
According to another embodiment of the present utility model, automatic tension-adjusting device comprises that further described top roller passes through motor-driven.
According to another embodiment of the present utility model, automatic tension-adjusting device comprises that further described automatic tension-adjusting device is used for warping machines.
According to another embodiment of the present utility model, automatic tension-adjusting device comprises that further described swing arm driving mechanism can realize by cylinder.
According to another embodiment of the present utility model, automatic tension-adjusting device comprises that further described swing arm driving mechanism can realize by oil cylinder.
The beneficial effects of the utility model are, warping machines automatic tension-adjusting device tension adjustment scope of the present utility model is big, can thoroughly compensate because when the variation of the humiture of external environment, starting during with operate as normal, the viscosity of oil is different, the tension variation of the descending process of yarn bobbin particularly, easy to adjust, be quick on the draw, the degree of regulation height can improve the warping quality greatly.

Wherein, 1, support, 3, top roller, 5, the top roller axle, 7, swing arm, 9, bottom roll, 11, the bottom roll axle, 13, swing arm driving mechanism, 15, tension detector, 17, control device, 19, motor.
The specific embodiment
With specific embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.Accompanying drawing is the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only shows the formation relevant with the utility model.
Automatic tension-adjusting device shown in Fig. 1～2, comprise support 1, support 1 is provided with top roller 3, top roller 3 is connected with support 1 by top roller axle 5, also be provided with the swing arm 7 around 5 rotations of top roller axle on the support 1, swing arm 7 is provided with bottom roll 9, and bottom roll 9 flexibly connects by bottom roll axle 11 and swing arm 7, automatic tension-adjusting device also comprises swing arm driving mechanism 13, and swing arm driving mechanism 13 can drive swing arm 7 around 5 rotations of top roller axle.Wherein, swing arm driving mechanism 13 can realize by motor-driven, also can use cylinder or hydraulic oil cylinder driving to realize, and, be by gear drive between swing arm driving mechanism 13 and the swing arm 7.
Warping machines as described in Figure 3 mainly is made up of automatic tension-adjusting device, tension detector 15, control device 17, motor 19, and the tension detector 15 main tension force that detect yarn, control device 17 then are 19 runnings of control motor.When implementing the utility model, during the warping machines operation, yarn with certain cornerite attached on top roller 3 surfaces, and there is not relative displacement, when tension detector 15 detected tension force and changes, tension detector 15 signaled to control device 17, and 17 of control device make 13 runnings of swing arm driving mechanism according to signal, and then control swing arm 7, thereby realize regulating automatically yarn tension around 5 rotations of top roller axle.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited in above-mentioned giving an example.Variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
