[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 and Figure 3 In one embodiment, a pen tube processing device includes: a fixed ring 2 fixedly connected to the upper end face of an operating table 1, the hollow shaft of the fixed ring 2 being parallel to the surface of the operating table 1; a telescopic cylinder 3 fixedly connected to the upper end face of the operating table 1, the telescopic cylinder 3 being positioned to the right of the fixed ring 2; a connecting block 4 positioned between the telescopic cylinder 3 and the fixed ring 2, the connecting block 4 being fixedly connected to the telescopic rod of the telescopic cylinder 3; a rotating motor 5 fixedly connected to the connecting block 4; and a connecting rod 6 positioned between the connecting block 4 and the fixed ring 2, the rotating shaft of the rotating motor 5 passing through the connecting rod 6. After connecting block 4, it is fixedly connected to one end of connecting rod 6; the air blowing pipe 7 is placed between connecting rod 6 and fixing ring 2, the air blowing pipe 7 is coaxial with the inner ring of fixing ring 2, one end of the air blowing pipe is closed and the other end is connected to the outside, the closed end of the air blowing pipe 7 is connected to the other end of connecting rod 6; several scraper blades 8 are evenly wrapped around the outer surface of air blowing pipe 7 and are engaged with the outer surface of air blowing pipe 7; the air pipe 9 is placed on air blowing pipe 7 and is connected to the inside of air blowing pipe 7; the controller 10 is placed on air blowing pipe 7 and is fixedly connected to the outer surface of air blowing pipe 7.

[0032] like Figure 3 As shown, the closed end of the air blowing pipe 7 is placed in the slot 11, and the air blowing pipe 7 is threadedly connected to the connecting rod 6 through the slot 11.

[0033] like Figure 3 and Figure 5 As shown, there are two retaining rings 12, both of which are wrapped around the outer surface of the air blowing pipe 7. The retaining rings 12 are located on the left side of the air pipe 9 and are fixedly connected to the outer surface of the air blowing pipe 7. The dust removal sleeve 13 is placed between the two retaining rings 12 and is wrapped around the outer surface of the air blowing pipe 7.

[0034] like Figure 1 and Figure 2 As shown, the cross-sectional shape of the scraper blade 8 is L-shaped. The vertical section of the L-shaped scraper blade 8 is perpendicular to the axis of the air blowing pipe 7 and is arc-shaped and fits the outer surface of the air blowing pipe 7. Several retaining strips 14 on the air blowing pipe 7 are arranged in groups of two, with each group of retaining strips 14 corresponding to one scraper blade 8. The retaining strips 14 are fixedly connected to the outer side of the air blowing pipe 7. The horizontal section of the L-shaped scraper blade 8 is placed between two retaining strips 14. The scraper blade 8 is engaged with the air blowing pipe 7 through the two retaining strips 14.

[0035] like Figure 4 As shown, the area of ​​the abutment 18 on the operating table 1 covers the area of ​​the inner ring of the fixing ring 2. The abutment 18 is placed on the left side of the fixing ring 2 and is fixedly connected to the upper end face of the operating table 1.

[0036] like Figure 4 As shown, the through hole 19 on the abutment 18 is coaxial with the inner ring of the fixing ring 2, and the right end of the through hole 19 is chamfered.

[0037] like Figure 4 As shown, the second slot 16 is placed on the right end face of the fixed ring 2 and is coaxial with the inner ring of the fixed ring 2. The limiting ring 15 is placed in the second slot 16. The length of the limiting ring 15 is longer than the depth of the second slot 16, so that it can be taken out from the second slot 16 when the limiting ring 15 is replaced. The outer side of the limiting ring 15 is press-fitted with the inner side of the second slot 16. The limiting ring 15 is engaged with the fixed ring 2 through the second slot 16. The limiting blocks 17 are evenly distributed in the inner ring of the limiting ring 15. The inner diameter of the through hole 19 is smaller than the outer diameter of the pen tube. The diameter that can be placed between several limiting blocks 17 needs to correspond to the outer diameter of the pen tube. The inner side of the limiting block 17 has low hardness to reduce damage to the outer surface of the pen tube.

[0038] In use, first select a suitable size air hose 7 and install it into the slot 11 on the connecting rod 6, so that the air hose 9 is connected to the air blowing device. At the same time, select a limiting ring 15 with a suitable limiting block 17 according to different pen shell diameters and insert it into the slot 16 on the fixing ring 2. Then, pass the blank pen tube through the limiting block 17 and onto the abutment block 18 on the operating table 1, with the opening of the pen tube aligned with the through hole 19. The inside of the pen tube is circular. You can open the telescopic cylinder 3 and rotate the motor 5 to allow the air hose 7 to extend into the pen tube. Inside, the back-and-forth movement and rotation allow the scraper blade 8 to scrape off excess burrs. Then, the controller 10 controls the air pipe 7 to blow away debris inside the pen tube. When the air pipe 7 enters the pen tube, the dust removal sleeve 13 on the air pipe 7 can also absorb fine debris, making the inside of the pen tube cleaner. Since the inside of the pen tube has ridges, only the telescopic cylinder 3 is opened, and a suitable scraper blade 8 is placed on the retaining strip 14 inside the pen tube, allowing the air pipe 7 to move back and forth, thus facilitating the removal of internal structural lines and debris from the pen tube after demolding.
