Description

[Detailed Description of the Invention] (Objective of the Invention) The present invention relates to a transmission device for a wire forming machine, which is characterized in that the rotation of a drive shaft is transmitted to each roller shaft via a timing belt.

(Prior art) Power was transmitted in conventional wire forming machines by a gear train consisting of a large number of gears, which produced a lot of noise during operation.
Furthermore, since the sum of the moments of inertia of the individual gears is quite large, the power consumption is large, a large torque is required at startup, and a large-capacity drive motor is required.

In addition, in order to interlock a large number of gears, if the machine is suddenly stopped due to operational trouble and restarted, the overall meshing backlash will increase, causing each roller to rotate incorrectly, causing damage to the sliver. There were various drawbacks such as the appearance of spots.

Furthermore, changing the draft ratio of the sliver in conventional gear train transmissions was done by replacing the transmission gears, which required a lot of time and wasted time when replacing the gears. , there were disadvantages such as getting the body dirty.

(Structure of the invention) The purpose of the invention is to eliminate the above-mentioned drawbacks, and when transmitting the rotation of the drive shaft to the calendar roller shaft and the draft roller shaft, transmission is performed using a timing belt instead of the conventional gear transmission. At the same time, the gist of the invention is to incorporate a continuously variable transmission device in order to change the draft rate of the sliver.

Further, a timing belt 31 is hooked around the belt pulley 27 fitted to the right end of the intermediate shaft 14 and the belt pulley 30 fitted to the input shaft 29 of the continuously variable transmission 28, so that rotation of the intermediate shaft 14 is prevented. It is transmitted to the human power shaft 29 of the gear shift transmission 28.

The input shaft 29 of the continuously variable transmission 28 protrudes outside to become a counter shaft 32, and a belt pulley 33 is fitted to the left end of the counter shaft 32, and a belt pulley 33 is fitted to the input shaft 35 of another continuously variable transmission 340.

The rotation of the human power shaft 29 of the continuously variable transmission N28 is changed in speed within the device 28 and transmitted to the output shaft 38. A timing belt 46 is hooked around the belt pulley 44 fitted to the right end of the lifter roller shaft 43 into which the lifter roller 42 is fitted, and the belt pulley 45 fitted to the output shaft 38.

In a similar configuration, a belt pulley 48 fitted to the output shaft 47 of another continuously variable transmission 34 and a backdraft roller shaft 40' fitted to the right end part of the backdraft roller 39' are fitted. A timing belt 46' is hung between the belt wheel 41' and the belt wheel gap fitted to the right end of the lifter roller shaft 43' fitted with the lifter roller 42', and the rotation of the output shaft 47 is directed to the back draft roller shaft. 40' and lifter roller shaft 43'.

In addition, in the figure, 49 is a top roller, 50 is a trumpet, and 5
Reference numeral 1 indicates a fleece gearing machine that converges strip-shaped fleece to form a rod-shaped sliver.

(Operation of the invention) When the drive motor M is started, the rotation of the drive shaft 4 is transmitted to the bottom calender roller shaft 2 via the belt 5, and the rotation of the bottom calender roller shaft 20 is transmitted to the top calender roller shaft via the timing belt 17. It is transmitted to the calendar roller shaft 7 and the front draft roller shaft 10, and also to the second draft roller shaft 19 via the timing belt 26.

．． This is done by increasing or decreasing the rotation speed of 39'.

(Effects of the invention) The transmission device in the wire forming machine of this invention transmits the rotation of the drive shaft to the calendar roller shaft and the draft roller shaft via the timing belt, so unlike the transmission using a conventional gear train, the transmission device The noise at the time is significantly reduced, and
Since the torque required to start the wire forming machine is significantly reduced, the capacity of the drive motor can be reduced, and each roller rotates reliably without irregular rotation, unlike transmission by a gear train. Therefore, sliver salt will not be generated when starting up the filament machine.

In addition, since the transmission device of the wire forming machine of the present invention incorporates a continuously variable transmission, the draft rate of the sliver can be changed steplessly, and the operation for changing the draft rate can be extremely simplified.
