Description
Technical Field
The invention relates to a blanking die mechanism, in particular to a blanking die mechanism of a high-speed flat plate type bubble cap machine.
Background
The blanking die mechanism of the conventional high-speed flat plate type bubble cap machine is shown in figures 1-1 and 1-2, and comprises an original upper cover plate 1, an original punch bottom plate 2, a steel ball outer guide sleeve 3, a steel ball sleeve 4, a guide post 5, an original punch 6, an original die 7, a punch positioning pin 8, a punch mounting screw 9, a stripper spring 10, a stripper mounting screw 11, a stripper 12, an original lower guide plate 13 and an original blanking die layout 14. The mechanism realizes the function of punching the packed blister layout by the flat plate type blister machine. The blanking die mechanism is arranged in a blanking station of the flat plate type bubble cap machine, the original male die bottom plate 2 and the original male die 6 are arranged on an original upper cover plate 1 of the blanking station which is static, and the original female die 7 is arranged on an original lower guide plate 13 of the blanking station which can move; the guiding function of a guiding pair consisting of the steel ball outer guiding sleeve 3, the steel ball sleeve 4 and the guiding post 5 is adopted; when the bubble cap machine works, the blanking station cam lifting mechanism is driven to operate, so that the original female die 7 arranged on the original lower guide plate 13 does linear lifting movement; the original male die 6 and the original female die 7 are closed, and the function of cutting the plate is completed.
Although the above-mentioned blanking die mechanism can also realize the blanking function of the plate, the blanking die layout of the single-row plate (namely the original blanking die layout 14 in fig. 1-1) is adopted, and the yield of the mechanism can not meet the requirement of the high-speed flat-plate type bubble cap machine under the stable working speed of the high-speed flat-plate type bubble cap machine. For example: the design of the original blanking die layout 14 of fig. 1-1 shows that the blister machine drives the blanking mechanism once, and the number of the blanked layout is 4 plates; when the high speed flat plate blister machine is operated at a steady speed of 60 punches/min, the throughput is 4x60=240 plates/min, which is far from reaching the 400 plates/min requirement of the high speed flat plate blister machine. Therefore, under the condition of ensuring that the blister machine does not overload, the prior art cannot meet the yield requirement of the high-speed flat plate type blister machine, and becomes a technical bottleneck which must be broken through for the development of the high-speed flat plate type blister machine.
As shown in fig. 2, the typesetting mode of the single-row layout is changed into 2 rows based on the structure of a blanking die in the background art. Here, in order to ensure the mechanical strength of the punching die, the distance between the edges of the die cavities of the two rows of dies must not be too small, and a distance of more than 5mm must be ensured (experiments prove that values below this value will cause deformation and damage of the edges of the dies). (it is suggested that the operation mode of the blanking die mechanism is that after the blister machine drives the blanking mechanism to operate once, the traction mechanism of the blister machine pulls the non-punched blister plate into the blanking die, wherein the pulling length L1 is the sum of the plate length L2 and the slitter edge length L3. As in fig. 1-1, the pulling length of the single-row typesetting mode is L1=L2+L3; as in fig. 2, the pulling length of the 2-row typesetting mode is the sum of the 2 plate lengths L2 and the slitter edge lengths L3 and the scrap length L5 between the 2 plate, namely, the pulling length is L4=2xL2+L3+L5), for example: when the bubble cap machine works, the blanking die of fig. 2 simultaneously punches 2 rows, and the single row of punched plates is 4 plates, namely 8 plates/punch; when the high speed flat plate blister machine is operated at a steady speed of 60 punches/min, the throughput is 8x60 = 480 plates/min, which, while meeting the 400 plates/min requirement of the high speed flat plate blister machine, results in more scrap (taking the above data as an example, scrap length L5 takes a minimum of 5mm, resulting in 5x60 = 300mm of scrap per minute). Therefore, under the condition of ensuring the high yield requirement of the high-speed plate type bubble cap machine, the prior art cannot meet the requirement of the high-speed plate type bubble cap machine on the packaging material to furthest reduce the waste, and becomes a technical bottleneck which must be broken through for the development of the high-speed plate type bubble cap machine.
