[0024] A bottle cap printing machine, such as Figure 1 and Figure 2As shown, it includes a frame 10; a conveyor belt 12 for conveying bottle caps is installed on the top surface of the frame 10, and two rollers 11 are rotatably connected to the top surface of the frame 10. A pressure block is also installed on the top of the frame 10. Specifically, a push cylinder is installed on the top surface of the frame 10, and the pressure block is fixedly connected to the output shaft of the push cylinder. A socket is provided on the side wall of the pressure block, and a thermocouple is inserted into the socket. The pressure block is pushed close to the conveyor belt 12 by the push cylinder, and the printed paper between the two rollers 11 is matched. The pressure block is used to press the printed paper on the bottle cap to form a corresponding print. The wall surface of the frame 10 is rotatably connected to a number of rollers, and the conveyor belt 12 is wound around the surface of the rollers. A motor is also fixedly installed on the wall surface of the frame 10, and the motor is connected to a power supply. The output shaft of the motor is fixedly connected to the roller to drive the conveyor belt 12 to operate and convey the bottle caps. This is an existing well-known technology and will not be described here.

[0025] like Figure 2 、 Figure 3 and Figure 4 As shown, the wall surface of the frame 10 is provided with a guiding structure for guiding the bottle cap, and the guiding structure includes a first guide rod 20, a second guide rod 21 and a third guide rod 22. The first guide rod 20, the second guide rod 21 and the third guide rod 22 are connected to each other and form a Z-shaped bent rod body. Two sets of guiding structures are symmetrically arranged on the top of the frame 10. The two bent rod bodies together form a trumpet-shaped guiding channel with a gradually narrowing opening. The guiding channel is located directly below the pressing block. The first guide rod 20, the second guide rod 21 and the third guide rod 22 are all rectangular rod structures. The first guide rod 20 is rotatably connected to the second guide rod 21, the second guide rod 21 is rotatably connected to the third guide rod 22, the adjusting screw 23 is rotatably connected to the side wall of the third guide rod 22, and the side wall of the third guide rod 22 is installed with a shaft. The adjusting screw 23 is fixedly connected to the inner ring of the bearing, and the guide structure also includes an adjusting screw 23, which is threadedly connected to the frame 10 and rotatably connected to the third guide rod 22. The two third guide rods 22 are both provided with the same adjusting screw 23, and the two adjusting screws 23 can be close to each other to adjust the opening size of the guide channel. In this solution, by setting two sets of guide structures, the two sets of guide structures jointly form a guide channel with a gradually narrowing opening. When the conveyor belt 12 transports the bottle caps toward the bottom of the pressing block, the bottle caps are sorted through the guide channel, and the smaller port of the guide channel is adapted to the diameter of the bottle caps, so that the messy bottle caps laid on the conveyor belt 12 can be sorted and arranged in a row by the guide channel, which is convenient for hot pressing printing of the pressing block and reduces the impact of printing deviation caused by the disordered placement of the bottle caps on the quality.

[0026] like Figure 4 and Figure 5As shown, the guide structure also includes a connecting column 30. The ends of the first guide rod 20 and the second guide rod 21 are fixedly connected to the same connecting column 30. One end of the second guide rod 21 is provided with an axial hole adapted to the connecting column 30. The connecting column 30 at the end of the first guide rod 20 rotates in the axial hole. The other end of the second guide rod 21 is fixedly installed with another connecting column 30. The end of the third guide rod 22 near the second guide rod 21 is provided with the same axial hole. The connecting column 30 at the end of the second guide rod 21 rotates in the axial hole of the third guide rod 22. Specifically, the connecting column 30 forms a cylindrical structure. By connecting the first guide rod 20, the second guide rod 21 and the third guide rod 22, the first guide rod 20 can adjust the angle around the second guide rod 21, and the second guide rod 21 can also rotate and adjust the angle around the third guide rod 22. Therefore, the width of the entrance of the guide channel formed by the first guide rod 20, the second guide rod 21 and the third guide rod 22 can be adjusted within a certain range. By rotating the adjusting screw 23, the first guide rod 20 is pushed close to the other first guide rod 20 to achieve the width adjustment of the guide channel outlet. It has higher adaptability to guiding bottle caps of different diameters and is more conducive to actual production applications.

[0027] like Figure 4 and Figure 5 The cam 32 is provided with a plurality of slots 31 on the top surface of the second guide rod 21 and the third guide rod 22, and the slots 31 are provided with a slot 31 on the top surface of each slot. The slot 31 forms a rectangular notch, and the slot 32 cooperates with the slot 31. The width of the slot 32 is greater than the length of the slot 31, the depth of the slot 31 is less than the thickness of the third guide rod 22, and the height of the slot 32 is greater than the depth of the slot 31. As a supplement to the above scheme, by inserting the slot 31 into the slot 31 of the connecting post 30 and the wall surface of the third guide rod 22, the connecting post 30 is restricted from rotating relative to the third guide rod 22 by the slot 32, thereby achieving the purpose of locking the angle of the second guide rod 21 and the third guide rod 22. On the basis of realizing flexible adjustment of the angle of the first guide rod 20 and the second guide rod 21, locking the angle of the first guide rod 20 and the second guide rod 21 is more convenient, easy to operate, and easy to use.

[0028] The working principle of the present invention is as follows: by setting two sets of guide structures, the two sets of guide structures together form a guide channel with a gradually narrowing opening. When the conveyor belt 12 transports the bottle caps toward the bottom of the pressing block, the bottle caps are sorted through the guide channel. The smaller port of the guide channel is adapted to the diameter of the bottle caps, so that the messy bottle caps laid on the conveyor belt 12 can be sorted and arranged in a row by the guide channel. The first guide rod 20, the second guide rod 21 and the third guide rod 22 are connected by two connecting columns 30. Then, the first guide rod 20 can adjust the angle around the second guide rod 21, and the second guide rod 21 can also adjust the angle around the third guide rod. 22 is rotated to adjust the angle, and thus the width of the entrance of the guide channel formed by the first guide rod 20, the second guide rod 21 and the third guide rod 22 can be adjusted within a certain range. The adjusting screw 23 is rotated to push the first guide rod 20 close to the other first guide rod 20, so as to adjust the width of the guide channel outlet and adapt to bottle caps of different diameters within a certain range. By inserting the slot 31 into the connecting column 30 and the slot 31 on the wall of the third guide rod 22, the connecting column 30 is restricted from rotating relative to the third guide rod 22 by the insert plate 32, thereby achieving the purpose of locking the angle of the second guide rod 21 and the third guide rod 22.
