When the straw is not wound in the shell 3, the three shift levers 53 are all in a horizontal distribution state; when the straw in the housing 3 is less, the straw can touch the three shift levers 53 in the movement process along with the second conveyor belt 32, so that the three shift levers 53 are limited by the limiting plate 61, the three shift levers 53 are static relative to the rotating shell 54, namely, the three shift levers and the rotating shell 54 are in an integrated state, at the moment, the straw shifts the shift levers 53 to enable the shift levers 53 to drive the rotating shell 54 to rotate, the rotating shell 54 drives the clamping plate 69 which is in contact with the driving plate 68 in the rotating direction to rotate through the driving plate 68, the clamping plate 69 drives the corresponding driving ring 59 to rotate, therefore, the driving ring 59 is connected with the fifth rotating shaft 65 through the volute spiral spring 58, and the fifth rotating shaft 65 is in a static state under the condition that the arc-shaped rack 46 does not slide, so that the corresponding volute spiral; the invention designs two scroll springs 58 with opposite rotation directions, which can ensure that the corresponding scroll springs 58 can exert force no matter which direction the rotating shell 54 swings towards, and cannot influence each other; the straws entering the shell 3 are disordered through the swinging of the deflector rod 53, the bundling process becomes firm, and the bundled straws are firmer and not easy to loosen; the disturbed straw falls to the lower side, and the straw is gradually extruded into bundles along with the increase of the quantity of the straw entering the shell 3.

The specific working process is as follows: when the forming equipment designed by the invention is used, the forming equipment is driven by the front driving equipment to move along the straw placing direction, the second motor 18 is controlled to work, the second motor 18 can drive the second rotating shaft 28 to rotate, the second rotating shaft 28 rotates to drive the chain wheel 23 on the second rotating shaft 28 to rotate, the chain wheel 23 rotates to drive the chain wheel 23 arranged on the first rotating shaft 24 to rotate through the chain 70, the second rotating shaft 28 rotates to drive the second transmission roller 29 to rotate, and the first rotating shaft 24 rotates to drive the first transmission roller 22 to rotate; the second transmission roller 29 rotates to drive the second transmission belt 32 to rotate; the first transmission roller 22 rotates to drive the first transmission belt 20 to rotate; during the movement of the device, the straw on the ground moves towards the inner side of the housing 3 along with the first conveyor belt 20 in the conveying mechanism 4, the straw entering the housing 3 rotates along with the second conveyor belt 32, during the rotation process, the straw can touch the three shift rods 53 which are horizontally arranged, therefore, the three shift rods 53 are limited by the limit plate 61, the three shift rods 53 are static relative to the rotating shell 54, namely, the straw is integrated with the rotating shell 54, at this time, the straw pulls the pulling rod 53 to make the pulling rod 53 drive the rotating shell 54 to rotate, the rotating shell 54 drives the clamping plate 69 which is contacted with the driving plate 68 in the rotating direction to rotate through the driving plate 68, the clamping plate 69 drives the corresponding driving ring 59 to rotate, at this time, the driving ring 59 is connected with the fifth rotating shaft 65 through the spiral spring 58, and the fifth rotating shaft 65 is in a static state under the condition that the arc-shaped rack 46 does not slide, so that the corresponding spiral spring 58 can exert an upward force; at the moment, the straws entering the shell 3 are disordered through the swinging of the deflector rod 53, the bundling process becomes firm, and the bundled straws are firmer and not easy to loosen; the disordered straws fall to the lower side, and the straws are gradually extruded into bundles along with the increase of the number of the straws entering the shell 3; when the straws in the shell 3 are wrapped to a certain degree and then are about to form a bundle, the straws push the push plate 47 to slide along the trapezoidal sliding groove 43, the push plate 47 slides to drive the arc-shaped rack 46 to slide, and the arc-shaped rack 46 slides to drive the gear 44 to rotate; the gear 44 rotates to drive the telescopic sleeve 64 to rotate, the telescopic sleeve 64 rotates to drive the arc plate 52 to rotate through the connecting rod 71, after the arc plate 52 contacts with the corresponding fan-shaped protrusion 51 in the rotating process, the protrusion 51 can extrude the arc plate 52 to move, the arc plate 52 moves to drive the upper end of the telescopic sleeve 64 to slide relative to the other end through the connecting rod 71, one end of the telescopic sleeve 64 moves to drive the limiting plate 61 installed on the limiting plate to move, so that the trigger notch 60 on the limiting plate 61 is matched with the shifting rod 53, the limiting plate 61 is relieved from limiting the shifting rod 53, the shifting rod 53 can be guaranteed to smoothly swing through relieving the limiting of the shifting rod 53, and the influence of a bundle in rotation. When the limit plate 61 is not pushed to move, the limit plate 61 is matched with the straight end 57 on the shifting lever 53 to limit the swinging of the shifting lever 53. The function of the return spring 56 is to tension the telescopic sleeve 64 so that the arc plate 52 is tightly pressed on the square notch 42 on the corresponding third arc plate 41; when the straw bundle is quickly finished, the three horizontally arranged shift levers 53 are influenced by the straw bundle, the disordering effect of the shift levers 53 is weakened due to the fact that the bundle is very large, at the moment, the shift levers 53 are easily damaged by impact in rotation, meanwhile, the rotation of the bundle is influenced by the existence of the shift levers 53, and the new straw attached to the surface of the quickly finished bundle is adversely influenced, the push plate 47 designed by the invention is pushed by the bundle when the bundle is quickly finished, the shift lever 53 is driven by the movement of the push plate 47 to rotate ninety degrees to be parallel to the plane of the elastic arc plate 9, so that the influence on the quickly finished bundle is reduced, and the bundle is protected from being damaged by impact; when swinging, if the shifting lever 53 is inserted into the bundle to be quickly finished and receives large resistance of the bundle to be quickly finished, the shifting lever 53 at the moment releases the limit, the shifting lever 53 can be separated from the bundle to be quickly finished with small resistance, and the shifting lever 53 can be ensured to smoothly swing when the bundle to be quickly finished is about to be finished.

After the straws in the shell 3 are bundled, the first motor 16 is controlled to work, the first motor 16 can drive the fourth rotating shaft 35 to rotate when working, the fourth rotating shaft 35 rotates to drive the swinging shell 17 to swing, the swinging shell 17 swings to drive the third supporting roller 36 installed on the swinging shell 17 to swing, then the second conveying belt 32 wound on the third supporting roller 36 is driven to swing around the fourth rotating shaft 35, the swinging shell 17 and the second conveying belt 32 on the rear side are opened, and the bundled straws are discharged.
