Abstract
The utility model discloses a tensioning structure, and belongs to the field of weaving machine components. The tensioning structure comprises a tensioning wheel, an installing plate, a fixing base, a screw and two adjusting nuts. The tensioning wheel is installed on the installing plate through a shaft, the bottom of the installing plate is provided with a flat key, the top face of the fixing base is provided with a sliding groove matched with the flat key, the fixing base is provided with two long-groove holes parallel to the center line of the sliding groove, the installing plate penetrates through the long-groove holes through bolts to be installed on the fixing base, the fixing base is provided with a thread through hole matched with the screw, the screw penetrates through the thread through hole to be fixedly connected with the installing plate, the two adjusting nuts are arranged on the screw in a sleeved mode in sequence and located on the outer side of the thread through hole, and the tensioning wheel is in a drum shape. Due to the fact that the screw is arranged on the installing plate, the position of the tensioning wheel can be adjusted by rotating the screw to enable the contact position between the tensioning wheel and a belt to be in an appropriate state. The tensioning structure is simple, and the manufacturing cost of a weaving machine is saved.
Description
Technical field
The utility model belongs to loom field of components, especially with between a kind of dobby head and loom main frame adopts bel-drivenn Tensioning structure relevant.
Background technique
Between dobby head and loom main frame, adopt belt transmission, due to belt in use for some time, the elasticity of belt can reduce, length can become, and belt lax in transmission process bears alternate load, has suitable impact force and vibration, need to carry out tensioner to belt, with vibration damping and locking, the existing Tensioning structure for loom and dobby head is comparatively complicated, and installs cumbersome.
Model utility content
The purpose of this utility model is intended to overcome complex structure that existing Tensioning structure exists, the defects such as trouble is installed, and a kind of Tensioning structure simple in structure is provided.
For this reason, the utility model is by the following technical solutions: a kind of Tensioning structure, it is characterized in that, comprise expansion tightening wheel, mounting plate, fixed base, screw rod and two adjusting nuts, expansion tightening wheel is installed on mounting plate by axle, the bottom of mounting plate arranges flat key, the chute that the end face setting of fixed base matches with flat key, fixed base is provided with two slotted holes parallel with chute center line, mounting plate passes slotted hole by bolt and is installed on fixed base, fixed base is provided with the tapped through hole matching with screw rod, screw rod is fixedly connected with mounting plate through tapped through hole, two adjusting nuts are sheathed on successively on screw rod and are positioned at the outside of described tapped through hole, described expansion tightening wheel is cydariform, can prevent that expansion tightening wheel from moving axially on belt, in the time need to regulating the position of expansion tightening wheel, bolt on mounting plate is unclamped, by rotating adjusting nut, screw rod drives mounting plate to move along chute, thereby makes the contact position of expansion tightening wheel and belt reach proper states, then by the bolt-locking on mounting plate, complete adjusting, by two adjusting nuts are set, two adjusting nuts abut against each other, and are difficult for loosening.
Use the utility model can reach following beneficial effect: the utility model is by being arranged on the screw rod on mounting plate, by rotating adjusting nut, regulate the position of expansion tightening wheel, make the contact position of expansion tightening wheel and belt reach proper states, the utility model structure is comparatively simple, has saved the manufacture cost of loom.
