step S1: the raw material pretreatment device pretreats raw materials such as polyethylene resin, an auxiliary agent and the like to form a first intermediate for heating;
step S2: the heater heats the first intermediate body to a semi-liquid state so as to form a second intermediate body for pipeline transportation;
step S3: the second intermediate body is conveyed to the inlet of the extruder at intervals according to a preset period through a pipeline (in other words, the second intermediate body in a semi-liquid state is not continuously conveyed through the pipeline any more, but the second intermediate body is conveyed to the extruder at intervals instead, generally, the preset period corresponds to that the second intermediate body corresponding to the next double-spliced bubble bag is conveyed to the inlet of the extruder after the last double-spliced bubble bag is subjected to pressure forming and conveyed away, but in order to prevent the occurrence of abnormal motion or need of temporary adjustment, a protection mechanism is introduced, which is described in detail below), a first sensor arranged at the inlet of the extruder immediately forms a first induction signal when detecting the second intermediate body (in other words, the second intermediate body is periodically conveyed to the inlet of the extruder, and once the second intermediate body reaches the inlet of the extruder, the first sensor immediately generates the first induction signal, the first sensing signal persists if the second intermediate is always at the inlet of the extruder);
step S4: a second sensor arranged at the outlet of the extruder immediately generates a second sensing signal when detecting the (processed) double-spliced bubble capsules (in other words, the second sensor immediately generates the second sensing signal as long as the double-spliced bubble capsules pass through the second sensor, and the second sensing signal continuously exists if the double-spliced bubble capsules are always at the outlet of the extruder), if and only if the interval duration between the moment of the second sensing signal and the adjacent latest first sensing signal is longer than a preset shortest processing period (the shortest processing period is different from the preset period in step S3, and in general, the shortest processing period should be slightly shorter than the preset period in step S3) (consideration of setting the shortest processing period is that a certain processing period is certainly required for producing the double-spliced bubble capsules, in order to prevent the extruder from causing abnormal factors such as excessively short molding time, further improving the protection mechanism) executes step S5, otherwise executes an alarm process;
step S5: and opening a feeding valve arranged at an inlet of the extruder, introducing a second intermediate (to be processed into the double-spliced bubble bag), prompting a user to input a current distance parameter between two bag bodies of the double-spliced bubble bag in a preset period (the preset period is different from the preset period in the step S3) by means of a touch screen and the like, and executing compression molding by the extruder according to a default distance parameter if the distance parameter is not input in the preset period, or executing compression molding according to the distance parameter input by the user.
It is worth mentioning that, in the embodiment, each double-spliced bubble bag is preceded by a distance parameter input process before being molded by an extruder, so that the double-spliced bubble bag is suitable for a small-batch production process and is convenient for highly individualizing and customizing the distance between two bag bodies of the double-spliced bubble bag.

step T4: a second sensor arranged at the outlet of the extruder immediately generates a second sensing signal when detecting the (processed) double-spliced bubble capsules (in other words, the second sensor immediately generates the second sensing signal as long as the double-spliced bubble capsules pass through the second sensor, and the second sensing signal continuously exists if the double-spliced bubble capsules are always at the outlet of the extruder), if and only if the interval duration between the moment of the second sensing signal and the adjacent latest first sensing signal is longer than a preset shortest processing period (the shortest processing period is different from the preset period in step S3, and in general, the shortest processing period should be slightly shorter than the preset period in step T3) (consideration of setting the shortest processing period is that a certain processing period is certainly required for producing the double-spliced bubble capsules, in order to prevent the extruder from causing abnormal factors such as excessively short molding time, further improvement of the protection mechanism) performs step T5, otherwise performs an alarm procedure;
step T5: the feed valve that sets up at the entrance of extruder is opened, introduces (treating to process for the double pin bubble bag) second midbody, shows the default interval parameter simultaneously (through means such as touch screen) and reminds the user to intervene (change) default interval parameter simultaneously, and the extruder carries out compression molding according to default interval parameter until there is new interval parameter to be input (just can carry out compression molding according to new interval parameter).
