Description
Technical field
The utility model belongs to synchronous belt production and processing technical field, and in particular to a kind of overlength seamless polyurethane is synchronous
Band production equipment.
Background technology
Traditional seamless polyurethane synchronous belt is produced by artificial centrifugal casting, and it is fixed to have using circular punch and matrix
Pre-prepared polyurethane solutions are poured into mold cavity by position.After casting complete, mold is transferred to curing oven.It is to be achieved
During the defined time, die sinking, trimming overlap cut shaping.Its maximum perimeter of the synchronous belt processed with the method is no more than
4000mm, it is difficult production that otherwise mold and manufacture craft, which are limited, and a kind of mold can only produce the synchronization of a kind of length and flute profile
Band, manufacture is expensive, and production efficiency is low.
Traditional polyurethane super long type synchronous belt takes the method plugged into be molded mostly.Cut required belt length in advance, so
Connecting port is cut out respectively at the both ends of band afterwards, i.e., synchronous belt both sides are broken into convex, recessed to tooth, is added after being coincide by high temperature
Heat makes connecting port fusion whole for an annular, but the skeleton rope that skeleton function is played in synchronous belt makes still in off-state
Its seam crossing tensile strength is minimum, leaves hidden danger of quality, is easily broken here in use, reduces synchronous belt
Service life.
Synchronous belt of plugging into easily is broken in high-load situations, this in seam crossing.In addition, docking synchronous belt is also easy to occur
It cuts that cut length improper, to the unmatched situation of tooth, causes unnecessary waste, not only influence transmission efficiency, also increase manufacture
Cost.
The content of the invention
The utility model provides a kind of overlength seamless polyurethane synchronous belt production equipment aiming at the above problem.
In order to realize the above-mentioned purpose of the utility model, the utility model adopts the following technical solution, and the utility model surpasses

The open type tooth form mold of belt wheel；It is provided with corresponding to toothed wheel and helping between belt wheel and toothed wheel and helps belt wheel upper extreme point line phase
Corresponding polyurethane extruder；Toothed wheel is provided with pinch roller in rack.
A kind of preferred embodiment of production equipment as the utility model overlength seamless polyurethane synchronous belt, positioned at poly- ammonia
Air knife group is provided between ester extruder and toothed wheel.
Another preferred embodiment of production equipment as the utility model overlength seamless polyurethane synchronous belt, in rack
The lower part of toothed wheel is provided with infantees wheel, cloth magazine is additionally provided in rack, is provided with and the bag above cloth magazine
The corresponding guide wheel group of cotton piece buff.
The beneficial effects of the utility model：The overlength polyurethane synchronous belt of the global formation of the utility model, due to entirety
The even and continuous winding in endless belt of endless belt seamless and tape base inner frame rope, avoids conventional overlength polyurethane synchronous belt
Seam crossing skeleton rope disconnects and causes the critical defect of the easily broken belt of stress concentration.Substantially increase the transmission of polyurethane synchronous belt
Reliability and service life.By contain strap process by strap closely glue be pressed in double wedge and concave tooth surface, improve synchronous belt
While the wearability of tooth, synchronous belt and meshing noise during belt wheel transmission are also reduced.
