Abstract
The utility model discloses a rapier belt pulley weft insertion accelerating mechanism. The rapier belt pulley weft insertion accelerating mechanism comprises a big gear and a pinion, wherein the big gear and the pinion are meshed with each other. The pinion is installed on a gear mounting rack, the gear mounting rack comprises a fixing seat and a rotating shaft, and the rotating shaft is movably connected to the fixing seat through a bearing. The pinion and a rapier belt pulley are fixed on the rotating shaft respectively. The rapier belt pulley weft insertion accelerating mechanism can effectively promote the rotation speed of the rapier belt pulley and improve the efficiency of wide-width weaving in the production process of large-wide-width fabrics.
Description
Technical field
The utility model relates to a kind of sword belt wheel wefting insertion speed increasing mechanism, belongs to field of textile machinery.
Background technology
The effect of weft insertion device is that the regular linear reciprocation that the uniform speed rotation with rapier loom main shaft is converted into the sword head moves.At present, the Weft insertion mechanism of rapier loom of selling on the market at home mainly comprises: (1) conjugate cam weft insertion device, the type mechanism is easy to satisfy the characteristics of motion of wefting insertion requirement, but the cam profile requirement on machining accuracy is quite high, as exists error just to produce impact; (2) plane six connecting rods send latitude, four link rob latitude mechanisms etc., can conveniently realize " relay " wefting insertion, but its motion of weft-insertion rule design flexibility is not as the conjugate cam weft insertion device; (3) space four-links weft insertion device, its motion of weft-insertion rule design flexibility send latitude, four link rob latitude mechanisms not as plane six connecting rods; The worm drive weft insertion device although the type mechanism is simple in structure, the transmission step is simplified, can not satisfy the stroke of weft insertion device in the wide cut weaving process.
Above-mentioned several Weft insertion mechanism of rapier loom is because output speed is fixing with the input speed ratio, therefore the maximal rate of the motion of sword head is restricted when rapier loom main shaft works.When weaving the cloth of large wide cut, just can not use like this weft insertion device of prior art, otherwise wefting insertion just may not begin to carry out beating-up before finishing.
Summary of the invention
For the defective of prior art, the utility model discloses a kind of sword belt wheel wefting insertion speed increasing mechanism, first based on the dynamics of gear, be a kind of speed increasing mechanism that can effectively promote Weft insertion mechanism of rapier loom output speed and input speed ratio in this area.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of sword belt wheel wefting insertion speed increasing mechanism, (the gear wheel diameter is greater than pinion to comprise gear wheel, pinion, compare the size of the two with this), gear wheel and pinion, wherein pinion is installed on the gear installing rack, the gear installing rack comprises holder and rotating shaft, and rotating shaft is movably connected in holder by bearing; Fixing pinion and sword belt wheel in the rotating shaft.
Based on said structure, when speed increasing mechanism of the present utility model is used for weft insertion device, amplify behind its output speed process gear wheel, the pinion.
Wherein, described sword belt wheel, pinion are positioned at an end of rotating shaft.
In order to realize the further amplification of rotating speed, the gear ratio of described gear wheel and pinion is higher than 1, for example can be 2:1.
Speed increasing mechanism using method of the present utility model is: (1) is fixed on the gear wheel of above-mentioned sword belt wheel wefting insertion speed increasing mechanism on the output shaft of weft insertion device; (2) the gear installing rack is fixed on for the rapier transmission box of placing weft insertion device.
By above-mentioned technological improvement, during use, gear wheel is fixed on the output shaft of weft insertion device, the gear installing rack is fixed on the rapier transmission box, and this rapier transmission box is used for placing weft insertion device.So amplify behind weft insertion device output speed process gear wheel, the pinion, for example the gear ratio of gear wheel and pinion is 2:1, and then the rotating speed from weft insertion device output has been exaggerated twice.The rotating speed of sword belt wheel can be improved thus, and this weft insertion device is gone in the weaving process of cloth of large wide cut.
Description of drawings
Fig. 1 is the structural representation of sword belt wheel wefting insertion speed increasing mechanism of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is sword belt wheel wefting insertion speed increasing mechanism working state schematic representation of the present utility model.
The specific embodiment
In following enforcement, the applicant provides a kind of specific implementation of the present utility model, can how to realize to show speed increasing mechanism of the present utility model, and it is not construed as limiting the utility model.Protection domain of the present utility model is covered by the equivalents of its claim and claim.
With reference to figure 1, speed increasing mechanism of the present utility model comprises gear wheel 2, pinion 1, gear installing rack 8, gear wheel and pinion.Pinion is installed on the gear installing rack, and gear wheel is installed on the gear installing rack equally, is fixed between two shell walls of speed increasing mechanism, and sword belt wheel 7 also is installed on the gear installing rack.
The gear installing rack comprises holder 6 and rotating shaft 5, and rotating shaft 5 is movably connected on the holder 6 by bearing.One end of rotating shaft is fixed with respectively sword belt wheel 7 and pinion 1.
In use, just gear wheel 2 is fixed on the output shaft 3 of weft insertion device, and the gear installing rack is fixed on the rapier transmission box 9, and this rapier transmission box is used for placing the weft insertion device (not shown).
With reference to figure 3, the action principle that has shown the utility model speed increasing mechanism, the output shaft of weft insertion device drives the rotation of gear wheel, because the gear wheel number of gears and/or diameter are higher than pinion, the two engagement causes the unit rotation driving pinion of gear wheel to rotate more distance, and pinion and sword belt wheel all are fixed in the rotating shaft, thereby so that the rotation of pinion passes to the sword belt wheel, it is compared with the output shaft that directly the sword belt wheel is directly installed on weft insertion device, obviously improve the sword belt wheel speed.
Claims (4)
1. a sword belt wheel wefting insertion speed increasing mechanism is characterized in that comprising gear wheel, pinion, gear wheel and pinion, and wherein pinion is installed on the gear installing rack, and the gear installing rack comprises holder and rotating shaft, and rotating shaft is movably connected in holder by bearing; Fixedly pinion and sword belt are taken turns respectively in the rotating shaft.
