The limiting component 3 is provided with the protruding part 3a, when the transfer mechanism 4 approaches to enter the transfer area 2a completely, the transfer mechanism 4 touches the protruding part 3a and pushes the limiting component 3 to rotate upwards, so that the waiting area 2b and the transfer area 2a are switched into a communicating state, and the TIP head box 8 on the waiting area 2b can enter the transfer area 2a under the action of a conveying belt.

As shown in fig. 2 and 3, in the present embodiment, the transfer mechanism 4 includes a base 4a, the base 4a is driven to move by a linear module 5, both ends of the base 4a are respectively provided with a left retention plate 4b and a right fixing plate 4c extending forward, and the inner side of the right fixing plate 4c is movably equipped with a clip 4d, specifically, the clip 4d can move in the direction of the line connecting the left retention plate 4b and the right fixing plate 4c, and the area between the clip 4d and the left retention plate 4b is a holding space for holding the TIP head box 8.

After the TIP head on the TIP head cartridge 8 at the loading area 1a is used up, the motor 6a drives the push rod 6b to move forward, so that the discarded TIP head cartridge 8 can be sent to the recycling area 1b.

In the above embodiment of the unloading mechanism 6, since the TIP head cartridge 8 is in the clamped state, the clamping force may hinder the push rod 6b from pushing the TIP head cartridge 8 toward the recovery zone 1b. To this end, the present embodiment also provides a force release mechanism to release the clamping force of the elastic member 4e to the TIP head cartridge 8. The following are provided:

referring to fig. 4 and 5, a longitudinal support plate 1d is fixedly mounted on a horizontal support plate 1c, a limit deflector rod 6d is rotatably mounted on the longitudinal support plate 1d, a tension spring 6e is connected between the limit deflector rod 6d and the longitudinal support plate 1d, the tension spring 6e can pull the limit deflector rod 6d to rotate forwards, a driving part 6c1 protruding rightwards is fixedly arranged on a swing arm 6c, the driving part 6c1 is positioned in front of the limit deflector rod 6d, and in the process of rotating the swing arm 6c backwards, the driving part 6c1 can force the limit deflector rod 6d to rotate backwards against the resistance of the tension spring 6 e.

After the TIP head of the TIP head box 8 is used up, the linear module 5 drives the transfer mechanism 4 to move rightwards until the clamping piece 4d of the transfer mechanism 4 exceeds the right end of the limit deflector rod 6 d. Then, the motor 6a drives the swing arm 6c to rotate forward, the driving part 6c1 releases the pressure on the limit deflector rod 6d, and the limit deflector rod 6d rotates forward under the traction action of the tension spring 6e until the limit deflector rod 6d physically interferes with the clamping piece 4d in the moving direction of the transfer mechanism 4. Then, the linear module 5 drives the transfer mechanism 4 to move leftwards, and in the process, the limit deflector rod 6d can block the clamping piece 4d to move leftwards, so that the distance between the clamping piece 4d and the left retention plate 4b is enlarged, and the clamping force on the TIP head box 8 is released. Finally, the motor 6a drives the swing arm 6c to rotate forward, and the push rod 6b can easily convey the TIP head box 8 to the recycling area 1b.
