The whole titre control system works as follows.
1. Measurement and comparison
In the reeling process, after raw silk formed by gathering a plurality of cocoons passes through a silk path system, silk strips 17 pass through a gauge wheel 2 at the front end of a titer sensor between a lower positioning drum wheel 1 and an upper positioning drum wheel 3 to be continuously detected, if the titer of the raw silk is thick, the friction force of the silk strips 17 acting on the groove wall of an annular groove of the gauge wheel is large, and the friction force acts on a fulcrum O of a long lever 402The friction torque is large; otherwise, it is small. The long lever 40 can rotate around the fulcrum O2And the friction force which is measured by the gauge wheel and reflects the titer change of the raw silk is compared with the fine limit friction force of a given value, the fine limit friction force is reflected by the balance moment of the second end of the lever, and the set value of the fine limit friction force can be adjusted by adjusting the gravity of the titer collective adjusting chain 16 arranged at the second end of the lever. When the fineness of the raw silk is smaller than the fineness of the fine limit and the corresponding friction force is smaller than the friction force of the fine limit, the second end of the long lever 40 is rotated to the upper limit 4b from the lower limit 4a on the fiber fixing frame 4, as shown in the position of fig. 2.
2. Exploration sports
The exploration movement is realized by a signal generating mechanism, and is completed by driving the swinging support rod 7 to swing periodically by the exploration cam 10a through the driven rod 8 and then transmitting the swinging support rod to the swinging pry plate 5. The swing lever 7 is pivoted on a fulcrum O7Is arranged on a bracket, one end of the bracket is connected with a swinging pry plate 5 through a pry plate connecting rod 6, and the other end is arranged at a connecting point O8Is connected with the driven rod 8. The other end of the driven rod 8 is connected with a feeding end upper pull rod 9, and a connection point O is arranged when the fineness of the silk threads is normal9And a fulcrum O7And (4) overlapping. Therefore, when the search cam 10a rotates in the direction of the arrow, the follower lever 8 is pushed to bring the swing lever 7 to the pivot point O7Swing up and down with the center, and make the swing crow plate 5 around the fulcrum O by the crow plate connecting rod 65Swing and perform exploration movement. Because the second end of the raw silk fineness long-time lever 40 is positioned at the lower limit position 4a, the swing pry plate 5 is not influenced by the raw silk fineness long-time lever, and the raw silk fineness long-time lever does not block when swinging, as shown in figure 1. At the same time of exploration movement, the integrally-made exploration thread-adding cam 10 pushes the thread-adding fork 11 around the fulcrum O11Swings but does not contact the thread feeding rod 12 and therefore does not drive the thread feeding rod 15 down, as shown in solid lines in fig. 1, and does not signal a thread feeding request.
3. Sending out a signal for requesting cocoon feeding in time
If the fineness of the raw silk detected is smaller than the fineness limit, the friction force of the silk 17 on the working surface is small, and the second end of the long lever 30 is at the position of the upper limit 4b and cannot swing upwards. The swinging pry plate 5 senses the state (namely senses a signal), is blocked and cannot continuously swing upwards, the thread adding cam 10 still continues to rotate and pushes the thread adding fork 11 to swing, but the swinging pry plate 5 is blocked, the driven rod 8 cannot continuously drive the swinging lever 7 to swing, and the driven rod uses O to drive the driven rod to swing8Lifting up as a fulcrum, and driving the feeding end upper pull rod 9 and the feeding end lower pull rod 13 to rise. At the same time, the exploration thread-adding cam 10 pushes the thread-adding fork 11 to move forward and swing, to contact with the thread-adding contact rod 12, and pushes it to make the thread-adding lower rod 13 rotate around the fulcrum O11Swing, so that the feeding rod 15 is driven by the feeding link 14 to rotate around the pivot point O15And the cocoon feeding machine is an execution mechanism, when the cocoon feeding machine descends and enters a thread feeding signal state, a sensing rod 18 on the cocoon feeding machine collides with a thread feeding rod 15 when the cocoon feeding machine arrives, and the cocoon feeding machine throws out a piece of tussah cocoons to feed the cocoons in time, as shown in figure 2.
After the cocoons are added, the silks continue to be drawn, the titer of the raw silk becomes thick, then the second end of the long rod 40 leaves the upper limit 4b and rotates to the lower limit 4a, and the sensing signal disappears. If the fineness of the raw silk is still fine after cocoon addition, the fineness sensor sends out a sensing signal again, the raw silk continuously and circularly moves, and finally the fineness of the raw silk is controlled within a target fineness range.
And the fineness collective adjusting chain 16 is used for collectively adjusting the fineness limit given value of each fineness sensor by changing the effective length of the adjusting chain when the process condition changes.
The above description is only an embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any changes or modifications within the scope of the present invention by those skilled in the art are covered by the present invention.
