[0028] It is worth noting that the inner cavity of the arc groove 200 is installed with several groups of rubber strips 201, and the rubber strips 201 contact the surface of the cylindrical shell without the hot stamping pattern to prevent the hot stamping pattern from directly contacting the inner cavity of the arc groove 200 and causing pattern wear, and the suction fan 202 draws air inward through the through hole 205 to increase the air flow rate between the rubber strips 201 and the arc groove 200, so that the hot stamping pattern on the surface of the cylindrical shell can be cooled faster.

[0030] Working principle:

[0031] First, place the injection-molded cylindrical shell in the inner cavity of the arc groove 200, and start the suction fan 202. The suction force of the suction fan 202 passes through the inner cavity of the suction block 204 and sucks the cylindrical shell through the through hole 205. The cylindrical shell is adsorbed in the inner cavity of the arc groove 200. Then adjust the parameters of the DSP to control the equipment. Then, the DSP controller 100 controls the telescopic end of the first electric push rod 107 to advance to one side, so that the surface of the hot stamping roller 102 contacts the surface of the cylindrical shell. Then, the DSP controller 100 controls the second electric push rod 301 to advance to one side, so that one end of the cylindrical shell abuts against one side of the rotating disk 302. At this time, the DSP controller 100 controls the servo motor 2 303 to rotate, driving the cylindrical shell to rotate, and driving the hot stamping roller 102 to rotate during the rotation. The texture on the surface of the hot stamping roller 102 is transferred to the surface of the cylindrical shell. At this time, the DSP controller 100 controls the servo motor 103 to rotate, performs hot stamping on the next group of cylindrical shells, and rotates the hot stamped cylindrical shells outward. When rotated to the outside, the inner cavity of the through hole 205 rotates out from the inner cavity of the suction block 204, and the suction force generated by the suction fan 202 disappears. The hot stamped cylindrical shell falls from the arc groove 200, and the staff can collect it. When it is necessary to hot stamp another group of printed color lines, texts, and patterns, first control the first electric push rod 107 to reset through the DSP controller 100. At this time, loosen the bolt 405 to retract the pressure block 404 into the inner cavity of the fixed box 401, release the restriction on the clamping block 406, and then rotate the fixing sleeve 400 so that the square hole 402 on the surface of the fixing sleeve 400 and the clamping groove on the surface of the clamping column 403 are in the same horizontal line, and lift the clamping block 406 of the hot stamping roller 102 upward to separate from the surface of the clamping column, and then replace the required hot stamping roller 102.

[0032] It is worth mentioning that the full-servo high-precision hot stamping equipment can be used to hot stamp two thick lines on the surface of the cylindrical level bubble, and then the printed cylindrical level bubble shell can be positioned on the injection mold for secondary injection molding. After CNC processing, the accuracy of the level bubble can be made ≤0.5‰, and the sealing of the level bubble can be achieved through liquid injection and ultrasonic welding to meet the requirements. The lines printed by the full-servo high-precision hot stamping equipment are brighter in color than the original ones, and lines, texts, and patterns of various colors can be printed.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
