Figure 1 and Figure 2As shown, a cigar tobacco leaf weaving machine according to an embodiment of the present invention includes: a frame 1, a cigarette neck clamping device 2, a cigarette neck pressing device 3, a thread roller device 4 and a needle threading device 5. Among them, the frame 1 has a horizontal flat plate 11 for laying tobacco leaves 9 flat. The cigarette neck clamping device 2 includes a cigarette neck lower clamping die 22 directly or indirectly fixed to the frame 1. In this embodiment, the cigarette neck clamping device 2 also includes a fixing member 21, the fixing member 21 is fixed to the frame 1, and the cigarette neck lower clamping die 22 is fixed to the fixing member 21. The length of the fixing member 21 is the same as that of the cigarette neck lower clamping die 22, and the width is greater than the width of the cigarette neck lower clamping die 22. The cigarette neck lower clamping die 22 is in the shape of an elongated strip, and the cigarette neck lower clamping die 22 is provided with a plurality of clamping slots 221 for accommodating the cigarette necks of cigar tobacco leaves, as shown in FIG. Figure 3 As shown, each slot 221 has an upward opening 222 and extends through the width of the lower neck die 22. Multiple slots 221 are evenly spaced along the length of the lower neck die 22. The lower neck die 22 also has a needle hole 223 extending through its length, which passes through all slots 221. The neck-pressing device 3 includes an upper neck press 31, which is positioned vertically opposite the lower neck die 22 and can move up and down above it. The upper neck press 31 cooperates with the lower neck die 22 to define the position of the cigar tobacco leaf 9. A thread guide 4 is located at one end of the neck-pressing device 2 and is wound with a thread 41. The threading device 5 is located at the other end of the cigarette neck device 2, and includes a threading hook 51 and a needle feeding device 52 that can drive the threading hook 51 to move toward or away from the thread guide device 4 in the threading hole 223. The threading hook 51 has a hook groove (not shown in the figure) on the end facing the thread guide device 4 that can hook the thread 41.

[0066] When the cigar leaf braiding machine is used to braid the cigar leaves, the necks of the plurality of cigar leaves 9 are evenly placed in the plurality of clamping grooves 221 of the neck lower clamping mold 22 by manual operation, and one neck is placed in each clamping groove 221. The necks of the plurality of cigar leaves 9 are pressed from top to bottom by the neck upper pressing mold 31, so as to fix the cigar leaves 9. Then the threading hook needle 51 is driven to sequentially pass through the necks of the plurality of cigar leaves 9 along the line 41, one end of the line 41 is wound on the line winding device 4, the other end of the line 41 is fixed in the hook groove of the threading hook needle 51, and then the threading hook needle 51 sequentially exits the necks of the plurality of cigar leaves 9, so that the line 41 sequentially strings the necks of the plurality of cigar leaves 9 into a string. The neck upper pressing mold 31 is removed from above the necks, the line 41 at both ends of the stringed cigar leaves 9 is cut, the necks are taken out of the clamping grooves 221 of the neck upper pressing mold 31, and the stringed cigar leaves 9 are taken away. The cigar leaf braiding machine has the neck lower clamping mold 22 with the uniformly arranged clamping grooves 221, and the cigar leaves 9 can be evenly laid, so that the plurality of cigar leaves 9 are uniformly arranged on the line 41, and the necks are positioned by the cooperation of the neck pressing device 3 and the neck lower clamping mold 22. Meanwhile, the threading hook needle is driven by the needle feeding device 52 to walk along the needle passing hole 223 of the neck lower clamping mold 22 for one round trip, so that the plurality of cigar leaves 9 can be strung, and the efficiency is much higher than that of manual threading of the necks. Meanwhile, the whole threading process only needs manual operation to wind the line 41 in the groove of the threading hook needle 51, so that the labor intensity is reduced.

[0067] In the embodiment, the length of the threading hook needle 51 is greater than the sum of the length of the neck lower clamping mold 22 and the distance from the end of the neck lower clamping mold 22 away from the line winding device 4 to the needle feeding device 52. It can be ensured that all the cigar leaves 9 arranged in the neck lower clamping mold 22 are simultaneously threaded on the needle, and one end of the needle is still left in the needle feeding device 52 to receive the driving of the needle feeding device 52.

[0068] As shown in FIG. 1, Figure 5 The neck lower clamping mold 22 is provided with a positioning groove 224 parallel to the needle passing hole 223, the lower part of the positioning groove 224 is through the upper part of the needle passing hole 223, the neck upper pressing mold 31 is provided with a positioning boss 311 parallel to the positioning groove 224, the positioning boss 311 is disconnected at a position opposite to the clamping groove 221 to form a space for accommodating the neck of the cigar leaf 9, and when the neck upper pressing mold 31 cooperates with the neck lower clamping mold 22, the positioning boss 311 cooperates with the positioning groove 224 to position the threading hook needle 51. The inner wall of the positioning groove 224 and the outer wall of the positioning boss 311 are both inclined relative to the vertical plane perpendicular to the horizontal plane, and the inclination angles are the same, and the inner wall of the positioning groove 224 and the outer wall of the positioning boss 311 form cooperation.

[0069] As shown in FIG. 1, Figure 6As shown, the frame 1 is provided with a neck pressing guide rail 123 extending up and down, and the cigarette neck pressing device 3 further includes a neck pressing frame 32 that can move up and down along the neck pressing guide rail 123 and a neck pressing driver 33 that drives the neck pressing frame 32 to move up and down. The cigarette neck upper pressing die 31 is fixed to the neck pressing frame 32. The neck pressing driver 33 can be selected from an electric push rod, a cylinder, or a hydraulic cylinder. In this embodiment, Figure 1 As shown, the frame 1 includes a drive bracket 12, which includes two vertical rods 122 and a crossbar 121 connecting the upper ends of the two vertical rods 122.

The neck pressing driver 33 is a cylinder, the cylinder body is connected to the crossbar 121 of the drive bracket 12, and the piston rod is connected to the neck pressing bracket 32.

[0070] like Figure 7 As shown, the wire puller device 4 includes a flat plate 11-shaped wire seat 42 fixed to the frame 1, a wire fixing rod 43 perpendicular to the wire seat 42 and fixed to the wire seat 42 at one end, a wire puller body 44 sleeved on the outside of the wire fixing rod 43 and rotatable relative to the wire fixing rod 43, a spring 45 sleeved on the outside of the wire fixing rod 43 and located at the upper end of the wire puller body 44, and a pressing plate 46 sleeved on the outside of the wire fixing rod 43, the pressing plate 46 is located between the spring 45 and the wire puller body 44, the other end of the wire fixing rod 43 has a thread, and the wire puller device 4 also includes a nut 47 that cooperates with the thread, and the nut 47 applies downward pressure to the spring 45 so that the spring 45 presses the wire puller body 44 toward the wire seat 42. When the pulley body 44 rotates, the wire 41 on the pulley body 44 can be lowered. By adjusting the matching position of the nut 47 and the wire fixing rod 43, the downward pressure exerted by the spring 45 on the pulley body 44 can be adjusted, thereby adjusting the tightness of the wire release of the pulley device 4. The lower the position of the nut 47, the greater the downward pressure exerted by the spring 45 on the pulley body 44, the greater the friction force exerted by the pulley body 44 on the wire seat 42, and the tighter the wire release of the pulley device 4. The higher the position of the nut 47, the smaller the downward pressure exerted by the spring 45 on the pulley body 44, the smaller the friction force exerted by the wire seat 42 on the pulley body 44, and the looser the wire release of the pulley device 4.

[0071] The wire roller device 4 also includes a wire take-up rod 48. In the present embodiment, the wire take-up rod 48 is horizontally arranged and perpendicular to the lower clamping die 22 of the cigarette neck. The wire take-up rod 48 is horizontally arranged and its position is higher than the lower end of the wire roller body 44. The wire take-up rod 48 is provided with a wire groove 49 for limiting the wire 41. The wire take-up rod 48 can prevent the wire 41 dropped from the wire roller device 4 from hanging on the flat plate 11-shaped wire seat 42 and being difficult to pick up. The wire groove 49 can guide the wire 41.

[0072] The needle feeding device 52 includes at least one needle feeding group 521, 522.Figure 8 and Figure 9 As shown, in this embodiment, the needle feeding device 52 includes a first needle feeding group 521 and a second needle feeding group 522. The first needle feeding group 521 includes a first needle feeding wheel 5211 and a second needle feeding wheel 5213. The first needle feeding wheel 5211 and the second needle feeding wheel 5213 have the same rotation speed and opposite rotation directions. The outer circumferential walls of the first needle feeding wheel 5211 and the second needle feeding wheel 5213 are both provided with needle feeding grooves 5121, 5214 surrounding the outer circumferential wall. The first needle feeding groove 5212 of the first needle feeding wheel 5211 and the second needle feeding groove 5214 of the second needle feeding wheel 5213 are relatively enclosed to form a needle feeding space for accommodating the threading crochet needle 51. When the first needle feeding wheel 5211 and the second needle feeding wheel 5213 rotate, at their relative positions, they respectively generate friction forces in the same direction on the threading crochet needle 51, thereby driving the threading crochet needle 51 to move. When Figure 9 When the first needle feeding wheel 5211 rotates clockwise and the second needle feeding wheel 5213 rotates counterclockwise, the threading hook 51 is applied to the threading hook 51. Figure 9 The force to the left in the middle, that is, provides power for the threading hook 51 to penetrate into the cigarette neck of the tobacco leaf 9. Figure 9 When the first needle feeding wheel 5211 rotates counterclockwise and the second needle feeding wheel 5213 rotates clockwise, the threading hook 51 is applied to the threading hook 51. Figure 9 The force to the right in the middle provides power for the threading hook 51 to withdraw from the cigarette neck and at the same time carry the thread 41 into the cigarette neck.

[0073] like Figure 9 As shown, the first needle feed group 521 also includes a first rotating shaft 5215 and a second rotating shaft 5216. The first needle feed wheel 5211 is mounted on the first rotating shaft 5215 and rotates synchronously with the first rotating shaft 5215. The first rotating shaft 5215 is also mounted with a first gear 5225 that rotates synchronously with the first rotating shaft 5215. The second needle feed wheel 5213 is mounted on the second rotating shaft 5216 and rotates synchronously with the second rotating shaft 5216.
