A kind of edge inward-folding device for loom is in transmission connection
Technical field
The utility model belongs to technical field of textile machine, especially is in transmission connection relevant with a kind of edge inward-folding device for loom.
Background technology
Synchronous belt pulley transmission is adopted in the weaving rapier loom tuck-in selvage motion of existing common textile machine, is begun by the loom central shaft, takes turns transmission by multi-stage, belt, drives the tuck-in selvage motion.There is following shortcoming in such drive mechanism: the syndeton part, be exposed to the machine outer surface more, and there is potential safety hazard, easily cause industrial accident; Synchronous belt pulley transmission can't change transmission direction; Synchronous belt pulley transmission does not have overload slipping protection function, there is no excessive bearing capacity, and belt is easily broken, needs irregularly to change, and even can affect production efficiency and rhythm.
The utility model content
The belt that the purpose of this utility model is intended to overcome the drive mechanism of existing rapier of loom machine Tucked-in selvage apparatus easily breaks, exists potential safety hazard, defective that production efficiency is low, a kind of integrally closed is provided, uses safety, and can change transmission direction and bearing capacity is larger and the more stable edge inward-folding device for loom of operation is in transmission connection.
For this reason, the utility model is by the following technical solutions: a kind of edge inward-folding device for loom is in transmission connection, comprise the transmission mechanism that is arranged between loom central shaft and Tucked-in selvage apparatus turning cylinder, it is characterized in that, described transmission mechanism comprises respectively two gear drive groups that are connected with turning cylinder with central shaft, described gear drive group comprises two intermeshing axle gears and main drive gear, the gear drive group that is connected with turning cylinder comprises three travelling gears of engaged transmission successively, and wherein last travelling gear is arranged on turning cylinder; Pass through chain gear transmission between described two gear drive groups.
Use the utility model can reach following beneficial effect: by the combination of gear and chain gear transmission, with original comparison that is in transmission connection, but integrally closed uses safer, gear drive not only can change transmission direction but also bearing capacity is larger, and long-play is more stable.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
as shown in Figure 1, the utility model comprises the transmission mechanism that is arranged between loom central shaft 2 and Tucked-in selvage apparatus turning cylinder 11, described transmission mechanism comprises respectively two gear drive groups that are connected with turning cylinder with central shaft, wholeheartedly shaft gear 1 is housed on central shaft 2, itself and a main drive gear 3 mesh, one sprocket wheel 4 is housed in the rotating shaft of main drive gear, it coordinates with sprocket for main drive 5 by chain 6 transmissions, sprocket for main drive coordinates with auxiliary driving sprocket wheel 8 by coaxial sprocket, the auxiliary driving sprocket wheel is by the gear Meshing Pair travelling gear 9 of coaxial setting, auxiliary driving gear 9 and 10 engagements of time travelling gear, inferior travelling gear is arranged on Tucked-in selvage apparatus turning cylinder 11, turning cylinder holds in 7 at a P profile shaft that is fixed in brest beams 12.Only need to pass through transmission step by step during use, the power of inputting from the loom central shaft drives the turning cylinder rotation at last, realizes the Tucked-in selvage apparatus normal operation.
