As shown in fig. 1 to 3, the telescopic engaging adjusting assembly 10 includes engaging pins 12 (movably inserted and assembled) installed on both sides of the engaging roller 4 and connected to the positions of the thick suction pipe groove 7 and the thin suction pipe groove 8, the engaging pins 12 are sleeved with engaging springs 13, and engaging cams 11 (which are driven by the concave and convex high and low surfaces of the rotating cam to move the engaging pins to pass through left and right) are installed on the roller frame 5 and at positions corresponding to the positions of the engaging pins. The telescopic straw nesting mechanism 21 is formed by the nesting roller 4, the roller frame 5, the nesting roller rolling control source 6 and the telescopic nesting adjusting component 10. A batch of straw raw materials (namely a plurality of groups of thick straws and thin straws) are placed in the straw raw material conveying assembly 2 (the straw raw materials are horizontally placed), and are conveyed in a vertical two-channel sequence mode and respectively enter corresponding thick straw grooves 7 and thin straw grooves 8 on the sleeve roller 4; then, the sleeve roller rolling control source 6 controls the sleeve roller 4 and the sleeve cam 11 to rotate, so that the sleeve thimble 12 is inserted and retracted along with the rotation of the sleeve cam 11, thereby sleeving the thick suction pipe in the thick suction pipe groove and the thin suction pipe in the thin suction pipe groove together, and then the sleeve roller rotates to enable the sleeved semi-finished suction pipe to fall on the surrounding conveyer belt component 22 of the molded suction pipe conveying mechanism 9 when the semi-finished suction pipe rotates to the lowest point.

As shown in fig. 1, 4 to 7, the straw necking mechanism 14 (positioning type) includes a necking base 15 mounted on the frame, a necking frame 17 is mounted on the necking base 15 (via a guide rail 16), a necking-crimping die 18 and a die-rotating power source 19 (which is a die-rotating motor) are mounted on the necking frame 17 and are interconnected, and the necking frame 17 is connected to a traverse power source 20 (which is a traverse cylinder). A telescopic pipe positioning component 30 is arranged between the necking frames 17 and above the forming suction pipe conveying mechanism 9, and is used for positioning the telescopic pipes (a group of sleeved thick suction pipes and thin suction pipes). Firstly, a necking and hemming die 18 and a die rotating power source 19 which are interconnected on a necking frame 17 are pushed to be in place by a transverse power source 20, and a straw semi-finished product (a sleeved state, namely a telescopic pipe) on a surrounding type conveyor belt component 22 of a forming straw conveying mechanism 9 is conveyed to the position of the necking frame 17 and is positioned by a telescopic pipe positioning component 30; at this time, the orifice of the telescopic tube (including the orifices of the thick suction tube and the thin suction tube) enters the necking and curling die 18, and the die rotating power source 19 drives the necking and curling die to rotate, so that the orifice of the telescopic tube is subjected to necking treatment, and the telescopic tube cannot be separated into two pipe fittings (i.e. the thick suction tube and the thin suction tube are separated) during telescopic operation.

As shown in fig. 1, 8 and 9, the molded straw conveying mechanism 9 (synchronous positioning type) comprises a circular conveying belt assembly 22 mounted on the frame 1, the circular conveying belt assembly 22 is connected with a main conveying power source 24 (mounted on the frame and used as a main conveying motor) through a first chain wheel chain assembly 23 (at the rear part), a lifting frame 25 is mounted on the frame 1 at the side edge of the circular conveying belt assembly 22, a flattening positioning conveying belt assembly 26 (also in a circular shape) is mounted on the lifting frame 25 and above the circular conveying belt assembly 22, a second chain wheel chain assembly 27 is mounted on the flattening positioning conveying belt assembly 26, the second chain wheel chain assembly 27 is connected with a third chain wheel chain assembly 29 mounted on the circular conveying belt assembly, the first chain wheel chain assembly 23 is connected with a first secondary chain wheel 31 (at the front part) through a chain wheel shaft assembly 28 (mounted on the circular conveying belt assembly), the first secondary sprocket 31 is connected to the third secondary sprocket of the third sprocket chain assembly 29. A gap is left between the looped belt assembly 22 and the flattening positioning belt assembly 26. The main conveying power source 24 is used to drive the first chain wheel and chain assembly 23 to make the endless conveying belt assembly 22 perform an endless conveying motion, and then the chain wheel and chain assembly 28 is used to drive the first secondary chain wheel and chain assembly 31 to drive the third chain wheel and chain assembly 29 and the third secondary chain wheel to rotate, and further drive the second chain wheel and chain assembly 27 to make the flattening positioning conveying belt assembly 26 perform an endless conveying motion. Therefore, the motion directions of the circular conveying belt component 22 and the flattening and positioning conveying belt component 26 are opposite, the same main conveying power source 24 is realized, and the formed straws are flattened, positioned and synchronously conveyed, so that the formed straws are favorably subjected to single-side oblique cutting by a straw oblique cutting mechanism to be manufactured into finished straws.
