[0028] Reference Figure 4 and Figure 5 The inner wall of the watercolor pen holder 6 is provided with two placement slots 14. A partition 20 is fixedly connected to the inner wall of the watercolor pen holder 6. By setting the placement slots 14 and the partition 20 together, it is convenient for users to put watercolor pens into the watercolor pen holder 6. At the same time, it is convenient for users to separate the watercolor pens placed in the watercolor pen holder 6, so as to facilitate users to process more watercolor pens.

[0029] Reference Figure 5 A mounting plate 19 is fixedly connected to one side of the watercolor pen holder 6. There are two mounting plates 19. A second motor 9 is fixedly connected to one side of the mounting plate 19. A gear 16 is fixedly connected to the output end of the second motor 9. A toothed plate 15 is meshed with the surface of the gear 16. By setting the mounting plate 19, the second motor 9, the gear 16 and the toothed plate 15 to work together, the reinforcing plate 18 and the limiting plate 17 can be moved, thereby providing power for the movement of the reinforcing plate 18 and the limiting plate 17.

[0030] Reference Figure 4 and Figure 5 A reinforcing plate 18 is fixedly connected to one side of the toothed plate 15, and a limiting plate 17 is fixedly connected to the bottom of the reinforcing plate 18. There are two limiting plates 17. One side of the limiting plate 17 extends to the inner wall of the watercolor pen holder 6 and is movably connected to the inner wall of the watercolor pen holder 6. By setting the reinforcing plate 18 and the limiting plate 17 to work together, the user can easily limit the watercolor pens placed in the watercolor pen holder 6, so that the user can prevent the watercolor pens in the watercolor pen holder 6 from moving in an emergency.

[0031] Reference Figure 6A slide rail 21 is fixedly connected to one side of the watercolor pen holder 6. A T-shaped slider 23 is slidably connected to the inner wall of the slide rail 21. One side of the T-shaped slider 23 is fixedly connected to one side of the toothed plate 15. By setting the slide rail 21 and the T-shaped slider 23 to work together, the stability of the toothed plate 15 when moving can be increased, and the toothed plate 15 can be prevented from tilting when moving.

[0032] Reference Figure 6 The inner wall of the slide rail 21 is provided with a T-shaped groove 22. The inner cavity of the T-shaped groove 22 contacts the surface of the T-shaped slider 23. By setting the T-shaped groove 22, a trajectory can be provided for the movement of the T-shaped slider 23, and the T-shaped slider 23 can be prevented from getting stuck when moving.

[0033] Reference Figure 4 The inner wall of the fixed plate 8 is rotatably connected to a rotating roller 11 via a bearing. There are two rotating rollers 11, and a conveyor belt 13 is rotatably connected between the surfaces of the two rotating rollers 11. There are two conveyor belts 13, and a number of stops 12 are fixedly connected to the surfaces of both conveyor belts 13. One of the rotating rollers 11 is fixedly connected to the output end of the first motor 10. By setting the first motor 10, the rotating rollers 11 and the conveyor belts 13 in cooperation, the watercolor pens that need to be clamped can be conveyed, thereby increasing the efficiency of the watercolor pens in the production process. By setting the stops 12, the conveyed watercolor pens can be limited, thereby increasing the stability of the watercolor pens in the conveying process.

[0034] Working Principle: To facilitate user handling of watercolor pens during processing and prevent damage and defective products, the air bladder 205 is first inflated using an external inflation device. During inflation, the user connects the outlet of the inflation device to the one-way valve 203, allowing gas to enter the air bladder 205 through the valve, thus changing its volume. After inflating the air bladder 205 to the appropriate amount, the user places the watercolor pens to be processed into the watercolor pen holder 6. Once an appropriate number of pens are placed in the holder, they will be subjected to their own pressure. The watercolor pens fall under their weight and enter the conveyor belt 13. The stop block 12 limits the movement of the pens in the conveyor belt 13. The user then starts the first motor 10 via an external power supply and switch. The output of the first motor 10 rotates, driving one of the rotating rollers 11 to rotate, which in turn drives the conveyor belt 13 to rotate. The rotating conveyor belt 13 then causes the other rotating roller 11 to rotate, conveying the watercolor pens into the conveyor belt 13. Once the watercolor pens are conveyed by the conveyor belt 13 to below the finger cylinder 201, the telescopic end of the electric telescopic rod 5 lowers the finger cylinder 201 to a suitable position. After placement, the output end of the finger cylinder 201 drives the gripper 202 to move, causing the two grippers 202 to move closer together, clamping the watercolor pen between the two airbags 205. The flexible contact clamping of the airbags 205 prevents damage to the watercolor pen and wear on the grippers 202. When gripping the watercolor pen, the grippers 202 drive the reinforcing post 204 and auxiliary claw 206 to move, increasing the contact area with the watercolor pen, thus making the gripping process more stable and secure, preventing it from falling off. After the watercolor pen is clamped between the two airbags 205, the rubber limiting baffle 207 limits the position of the gripped watercolor pen, preventing... The watercolor pens, which are not clamped between the two airbags 205, can move to prevent them from falling out. When the user needs to stop feeding the watercolor pens in the watercolor pen holder 6, the user can start the second motor 9 through an external power supply and switch. When the second motor 9 rotates, it drives the gear 16 to rotate. The rotating gear 16 will drive the toothed plate 15 that meshes with it to move. The moving toothed plate 15 will drive the T-shaped slider 23 to slide in the T-shaped groove 22. When the toothed plate 15 moves, it will drive the reinforcing plate 18 and the limiting plate 17 to move, so that the limiting plate 17 enters the watercolor pen holder 6 and limits the watercolor pens in the watercolor pen holder 6.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
