The application has a reasonable structure and can move the paper tube forward. By running the second motor to drive the side-rotating drive wheel to rotate, the paper tube can be rolled in its original position, which is convenient for flexible change of the punching position.

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0026] See also Figure 1-6 The utility model provides a technical solution: a punching device for paper tube production, comprising a bottom plate 1, a fixing plate 2 is fixedly connected to the top of the bottom plate 1, a motor 7 is arranged on the top of the fixing plate 2, a drill bit 10 is fixedly connected to the bottom of the output shaft of the motor 7, and a suction mechanism 5 is arranged on the top of the fixing plate 2;

[0027] The suction mechanism 5 includes a protective box 501 , a plurality of air inlet holes 502 and a suction tube 503 . The rear side of the suction tube 503 is fixedly connected to the front side of the protective box 501 , and the air inlet holes 502 are provided inside the protective box 501 .

[0028] In this embodiment: by fixing the external vacuum cleaner to the suction pipe 503, the paper tube to be punched is placed inside the arc groove 14 and adjusted to a suitable position. At this time, the anti-slip strip 12 can stably support and guide the paper tube to prevent the paper tube from tilting and sliding. At this time, the motor 7 is controlled to rotate and move downward to punch holes in the paper tube. At this time, the protective box 501 will cover the open position of the paper tube and the drill bit 10. At this time, the external vacuum cleaner is controlled to work, and the paper tube inside the protective box 501 can be sucked through the suction pipe 503. The debris generated by drilling is sucked away, and the air outside the protective box 501 is pumped into the protective box 501 through the air inlet 502 to take away the temperature of the surface of the drill bit 10 and cool the drill bit 10, thereby avoiding the problem that most existing structures for drilling holes in paper tubes do not have a structure for sucking away debris and dissipating heat for the drill bit 10. As the drill bit 10 continuously drills holes in the paper tube, the temperature will gradually rise. When the drill bit 10 with a higher temperature is used to drill holes in the paper tube, it is easy to cause the paper tube to burn, posing a safety hazard.

[0031] As a technical optimization solution of the utility model, a limiting ring 9 is fixedly sleeved on the surface of the motor 7 , and the top of the inner wall of the protection box 501 contacts the surface of the limiting ring 9 .

[0032] In this embodiment: by contacting the top of the inner wall of the protection box 501 with the surface of the limiting ring 9, the limiting ring 9 can limit the protection box 501 to prevent the protection box 501 from being separated from the motor 7, thereby achieving the effect of limiting the protection box 501.

[0033] As a technical optimization solution of the utility model, an arc groove 14 is opened inside the fixed plate 2, and the inner wall of the arc groove 14 is fixedly connected with an anti-slip strip 12. The number of anti-slip strips 12 is several and evenly distributed on the inner wall of the arc groove 14.

[0034] In this embodiment: the paper tube is supported against slip by the arc-shaped anti-slip strip 12, and the notches on both sides of the protective box 501 assist in limiting the position of the paper tube, so that the paper tube can be stably placed at the bottom of the drill bit 10, achieving the effect of allowing the paper tube to be stably placed at the bottom of the drill bit 10.

[0035] As a technical optimization solution of the present invention, a scale groove 11 is opened on the front side of the top of the fixing plate 2 , and the number of the scale grooves 11 is several and evenly distributed on the top of the fixing plate 2 .

[0037] As a technical optimization solution of the present invention, an indicator block 13 is fixedly connected to the top of the fixed plate 2 , and the indicating position of the indicator block 13 is the axis center of the drill bit 10 .

[0038] In this embodiment: by observing the indicator block 13 and the scale groove 11, since the indicated position of the indicator block 13 is the axis of the drill bit 10, the position of the hole punched in the paper tube can be determined, thereby achieving the effect of facilitating the determination of the hole punching position in the paper tube.

[0039] As a technical optimization solution of the utility model, a fixing frame 3 is fixedly connected to the rear side of the top of the base plate 1, an electric telescopic rod 4 is fixedly connected to the bottom of the fixing frame 3, and the bottom of the telescopic end of the electric telescopic rod 4 is fixedly connected to the top of the motor 7.

[0040] In this embodiment, by controlling the telescopic end of the electric telescopic rod 4 to move downward, the motor 7 and the drill bit 10 can be driven to move downward, thereby achieving the effect of driving the motor 7 to move.

[0041] As a technical optimization solution of the present invention, the four corners of the bottom of the base plate 1 are fixedly connected with supporting legs 6.

Then, the external vacuum cleaner is fixedly connected to the suction pipe 503. Then, the paper tube to be punched is placed inside the arc groove 14. By observing the scale groove 11 and the indicator block 13, the paper tube can be easily moved to the position where the hole needs to be punched and aligned with the drill bit 10. At this time, the anti-slip strip 12 can provide stable support and guidance for the paper tube to prevent the paper tube from tilting and sliding. At this time, the motor 7 is controlled to rotate. The rotation of the motor 7 can drive the drill bit 10 to rotate through the output shaft. At this time, the telescopic end of the electric telescopic rod 4 is controlled to move downward, so that the drill bit 10 can punch holes in the paper tube. At this time, the protective box 501 will cover the open position of the paper tube and the drill bit 10. At this time, the external vacuum cleaner is controlled to work, and the paper tube can be punched through the suction pipe 5 03 The debris generated by punching the paper tube inside the protective box 501 is sucked out, and the air outside the protective box 501 is pumped into the protective box 501 through the air inlet 502 to take away the temperature of the surface of the drill bit 10 and cool the drill bit 10, thereby avoiding the problem that most existing structures for punching holes in paper tubes do not have a structure for sucking out debris and dissipating heat for the drill bit 10. The temperature of the drill bit 10 will gradually rise after it continuously drills holes in the paper tube. When the drill bit 10 with a higher temperature is drilling holes in the paper tube, it is easy to cause the paper tube to burn, posing a safety hazard. The paper tube is provided with an anti-slip support by the arc-shaped anti-slip strip 12, so that the paper tube can remain stable when the drill bit 10 is punching holes in the paper tube, and the arc-shaped notches on both sides of the protective box 501 can also assist in limiting the position of the paper tube to prevent the paper tube from displacement.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
