[0065] like Figure 8 and Fig. 9 As shown, the structure of the feeding component 1 is: first, the feeding component 1 includes a conveyor belt 11, and the conveyor belt 11 is used to transport the paper tube 4. At the same time, the conveyor belt 11 has two rollers built in, and the end of one of the rollers is provided with a roller 111, and the roller 111 can be connected to the driving source six 66 through a belt, a chain, etc., so that the roller 111 can rotate under the drive of the driving source six 66, and drive the conveyor belt 11 to rotate.

For example, two limiting plates 12 are symmetrically provided on the top of the conveyor belt 11, and the two limiting plates 12 are located on both sides of the paper tube 4, so as to limit the position of the paper tube 4.

[0067] The limit plate 12 can also be equipped with an adjustment structure to become adjustable to adapt to different paper tubes 4. The adjustment structure can adopt a screw structure, and then the limit plate 12 is threadedly connected to the screw, so that the rotation of the screw drives the movement of the limit plate 12.

[0072] Furthermore, the above two moving structures can exist at the same time, that is, the paper tube 4 is restricted in two directions.

[0083] In summary, the entire working principle is as follows: first, the conveyor belt 11 rotates and drives the paper tube 4 to move under the drive of the driving source six 66. When the paper tube 4 reaches the designated position, that is, below the adsorbent 22, the adsorbent 22 moves down to adsorb the paper tube 4. After adsorption, the adsorbent 22 places the paper tube 4 on the V-shaped plate 32 under the drive of the driving source three 63 and the driving source two 62, and the adsorbent 22 moves to the initial position after the paper tube 4 is placed. At this time, the limiting plate three 33 is located above the paper tube 4 and contacts the paper tube 4 under the drive of the driving source eight 68 and the driving source nine 69, that is, the paper tube 4 is located between the V-shaped plate 32 and the limiting plate three 33.

At this time, the bottom plate 31 will move under the drive of the driving source seven 67 and synchronously drive the movement of the V-shaped plate 32 and the limiting plate three 33, so that the paper tube 4 is sleeved on the paper winding roller 5, and after the paper tube 4 is placed, the V-shaped plate 32 and the limiting plate three 33 are moved to the starting position.

[0084] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model.
