[0021] Embodiment: A high-speed rotating printer.

[0022] Refer to Figures 1 to 5As shown in the figure, a high-speed rotary printer includes: a frame 1, and a divider 7 installed on the frame 1. The relationship between the input shaft and the output shaft of the divider 7 is that when the input shaft rotates 300°, the output shaft rotates 90°, and when the input rotates another 60°, the output shaft stops. A second spiral bevel gear 4 is installed at the top of the input shaft of the divider 7, and a first spur gear 5 is fixedly installed below the second spiral bevel gear 4. Among them, the input shaft of the divider 7, the second spiral bevel gear 4, and the first spur gear 5 rotate synchronously. The main transmission shaft 2 is horizontally fixed at the top of the frame 1, and the rear end of the main transmission shaft 2 is connected to the output shaft of the drive motor. The main transmission shaft 2 is precisely rotated by the drive motor. A first spiral bevel gear 3 is installed in the middle of the main transmission shaft 2. The first spiral bevel gear 3 meshes with the second spiral bevel gear 4. A second spur gear 6 is installed on one side of the first spur gear 5 and meshes with the first spur gear 5. The diameter ratio of the first spur gear 5 to the second spur gear 6 is 1:2. The synchronous transmission shaft 11 is fixed on the second spur gear 6 and is vertically arranged downward. A first synchronous pulley 8 is fixed on the synchronous transmission shaft 11. The rotating arm 16 is fixed on the output shaft of the divider 7 through the swing arm transmission shaft 17. The rotating arm 16 rotates following the output shaft of the divider 7. Four printing mounting seats 161 are arranged on the rotating arm 16 in a circumferential array. A printing mechanism 13 is correspondingly installed on each printing mounting seat 161. Among them, the information printed by each printing mechanism 13 can be the same or different, and can be set according to actual requirements. A printing mechanism 13 is correspondingly installed on each printing mounting seat. The bearing sleeve 14 is sleeved outside the swing arm transmission shaft 17, and the bearing sleeve 14 can rotate independently relative to the swing arm transmission shaft 17. A second synchronous pulley 10 is installed on the top of the bearing sleeve 14. The first synchronous pulley 8 and the second synchronous pulley 10 are connected by a synchronous belt 9. The end face cam 12 is installed at the bottom of the bearing sleeve 14 through the cam mounting seat 15. The end face cam 12 includes a cam body 121. A curve groove 122 is opened on the side end face of the cam body 121. An inner groove 124 is arranged at the top of the cam body 121. A connecting shaft 123 is arranged at the center of the inner groove 124. The connecting shaft 123 is fixedly connected to the bottom of the bearing sleeve 14.

[0023] Referring to Figure 4As shown, the printing mechanism 13 includes a lower pressing seat 133. The CF bearing 132 is horizontally installed on the lower pressing seat 133. The rear end of the CF bearing 132 is embedded in a curve groove 122 formed on the side end face of the end face cam 12. The pressing rod 131 longitudinally penetrates through the lower pressing seat 133 and the printing mounting seat 161 and extends downward. Two parallel guide rods 134 penetrate through the printing mounting seat 161 and extend downward. The left and right ends of the lower pressing seat 133 are sleeved on the guide rods 134. The rubber head mounting seat 136 is fixedly installed at the bottom of the lower pressing rod 131. The printing rubber head 137 is fixed on the rubber head mounting seat 136. A spring 135 is sleeved on the surface of the pressing rod 131 in the area between the lower pressing seat 133 and the printing mounting seat 161, and a spring 135 is also sleeved on the surface of the pressing rod 131 in the area between the printing mounting seat 161 and the rubber head mounting seat 136. The spring 135 serves to protect the printing rubber head 137. During the actual operation process, the end face cam 12 is driven to rotate by the second synchronous pulley 10. The output shaft of the divider 7 drives the rotating arm 16 to move through the rotating arm transmission shaft 17. The end face cam 12 can rotate flexibly on the outside of the rotating arm 16 through the bearing sleeve 14. During the rotation of the end face cam 12, the CF bearing 132 can be controlled to move in the curve groove 122 through the curve groove 122. At the same time, during the rotation of the rotating arm 16, the CF bearing 132 is also driven to move in the curve groove 122. Through the angle difference formed during the simultaneous rotation of the end face cam 12 and the rotating arm 16, the CF bearing 132 drives the lower pressing seat 133 and the pressing rod 131 to move up and down, thereby driving the printing rubber head 137 to move up and down, realizing the high-speed up and down movement of the printing rubber head 137 and the cyclic printing function.

[0024] This high-speed rotary printer is ingeniously designed and easy to operate. It adopts a component mechanism of a parallel shaft divider driving gears and synchronous pulleys to achieve the high-speed up-and-down movement of the printing mechanism and the function of cyclic printing. During actual operation, the driving motor drives the main transmission shaft 2 to rotate, drives the second spiral bevel gear 4 to rotate through the first spiral bevel gear 3, the second spiral bevel gear 4 drives the input shaft of the divider 7 to rotate. During the rotation of the input shaft of the divider 7, the second spur gear 6 is driven to rotate through the first spur gear 5, and the second spur gear 6 drives the synchronous transmission shaft 11 to rotate. The synchronous transmission shaft 11 drives the first synchronous pulley 8 to rotate. The first synchronous pulley 8 drives the second synchronous pulley 10 to rotate through the synchronous belt 9. The rotation of the second synchronous pulley 10 drives the end face cam 12 to rotate through the bearing sleeve 14. At the same time, during the rotation of the input shaft of the divider 7, through the distribution of the rotating arm example, since the relationship between the input shaft and the output shaft of the divider 7 is that when the input shaft rotates 300°, the output shaft rotates 90°, and when the input rotates another 60°, the output shaft is stationary, and at the same time, the diameter ratio of the first spur gear 5 to the second spur gear 6 is 1:2. Therefore, during the actual transmission process, when the end face cam 12 rotates 180°, the rotating arm 16 just rotates 90°. Exactly, the end face cam 12 rotates 90° more than the rotating arm 16, resulting in a relative movement between the end face cam 12 and the rotating arm 16. 90° is exactly the cycle of a round-trip movement of the printing rubber head 137 in the printing mechanism 13 from bottom to top. Thus, the function of high-speed printing is achieved through the precise cooperation between the end face cam 12 and the rotating arm 16, and the printing efficiency can be as high as 180 per minute.

[0025] The above is the preferred embodiment of the present invention, but the present invention should not be limited to the content disclosed in this embodiment and the drawings. Therefore, all equivalent or modified implementations completed without departing from the spirit disclosed by the present invention fall within the protection scope of the present invention.
