Referring to fig. 4 and 5, the control unit includes a fixing sleeve 13 and a fixing shaft 25, and the fixing shaft 25 is horizontally welded to the frame 1. The fixed shaft 25 is provided with a plurality of spiral sections, the spiral grooves 15 are formed in the spiral sections respectively, the number of the spiral sections in the embodiment is four, the four spiral sections are arranged intermittently and uniformly along the axial direction of the fixed shaft 25, the connecting grooves 16 are formed among the spiral sections, and the connecting grooves 16 are communicated with the spiral grooves 15 of the spiral sections. The fixed shaft 25 passes through the fixed sleeve 13 and is in sliding fit with the fixed sleeve 13. The inner wall of the fixed sleeve 13 is welded with a bulge 14, and the bulge 14 can be clamped in the spiral groove 15 and the connecting groove 16 and can slide along the spiral groove 15. The fixing sleeve 13 is positioned in the middle of the placing plate 19 and welded with the placing plate 19.

The specific implementation process is as follows: when using, bond the one end of film on the wind-up roll, then will treat that the cotton of bubble of arranging is placed on placing board 19, then starter motor 4, and motor 4 rotates and drives incomplete gear 7 through pivot 22 and rotate. The incomplete gear 7 intermittently meshes with the first transmission gear 6 and the second transmission gear 23 during rotation. When the incomplete gear 7 is meshed with the second transmission gear 23, the incomplete gear 7 is not meshed with the first transmission gear 6, so that the incomplete gear 7 cannot drive the first transmission gear 6 to rotate, the wind-up roll 2 does not rotate at the moment, and the film is in a static state on the workbench. At this time, the incomplete gear 7 is meshed with the second transmission gear 23, the incomplete gear 7 rotates to drive the second transmission gear 23 to rotate, and the second transmission gear 23 drives the first eccentric gear 8 to rotate through the second rotating shaft 24. Because the first eccentric gear 8 is meshed with the second eccentric gear 10, when the first eccentric gear 8 and the second eccentric gear 10 rotate, the distance between the axle centers of the first eccentric gear 8 and the second eccentric gear 10 changes, that is, the connecting shaft 12 slides back and forth along the sliding sleeve 21 and drives the storage bin 17 to slide back and forth. The arrangement of the spring 9 ensures that the first eccentric gear 8 and the second eccentric gear 10 are always in mesh.

Because the connecting shaft 12 is connected with the storage bin 17, the storage bin 17 is pushed to move horizontally along the fixed shaft 25 when the connecting shaft 12 slides along the sliding sleeve 21. The retaining sleeve 13 will move with the storage bin 17. And in the fixed cover 13 slip in-process, when arch 14 entered into spiral groove 15, arch 14 slides in spiral groove 15 and can drive fixed cover 13 and rotate, and the board 19 of placing with fixed cover 13 fixed connection also can rotate, and export 18 is opened this moment, and the cotton ejection of compact of bubble is followed export 18 and is fallen on the film and is stuck, reaches the effect of paster. When the projection 14 is inserted into the coupling groove 16, the placing plate 19 is again in a horizontal state to block the outlet 18. Thus, when the fixing sleeve 13 moves to a spiral section, one foam can be placed, namely, after the connecting shaft 12 moves transversely once, four foams can be placed.

The motor 4 drives the rotating shaft 22 to continue rotating, at this time, the incomplete gear 7 is not meshed with the second transmission gear 23 and is meshed with the first transmission gear 6, namely, the first transmission gear 6 rotates and drives the first belt pulley to rotate, the first belt pulley drives the second belt pulley to rotate through a belt, and the second belt pulley drives the winding roller 2 to rotate so that the film is wound partially. At this point, a new film moves under the storage bin 17. When the incomplete gear 7 rotates to be meshed with the second transmission gear 23, the process of placing the foam by the placing plate 19 is repeated.

In this implementation, just only adopt a power supply just can drive simultaneously and place board 19 and place the cotton and wind-up roll 2 rolling films of bubble, reached the cotton effect of automatic collection arrangement bubble.

The technical personnel in the field can determine the parameters such as the gear tooth number, the gear ratio and the like of the incomplete gear, the first transmission gear 6 and the second transmission gear 6 according to the actual requirement.
