Specific implementation

[0030] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and are not used to limit the scope of the utility model.

[0031] As Figure 1As shown, the safety type bag buckle machine provided by the embodiment is improved and upgraded on the basis of the bag buckle machine disclosed in the document No. CN211483193U "A bag buckle machine", which comprises a rack 1, a workbench 2, a driving motor 3 and a stamping die 4. The driving motor 3 is installed on the rack 1, and the driving end thereof faces upward. The workbench 2 is horizontally arranged and is in transmission connection with the driving end of the driving motor 3. The upper end of the workbench 2 is provided with an upper buckle die 51, a falling buckle die 52 and a pressing buckle die 53. The stamping die 4 is installed on the rack 1 and is located above the workbench 2. The punch 41 of the stamping die 4 faces downward. The driving motor 3 is used to drive the workbench 2 to horizontally swing to align the upper buckle die 51, the falling buckle die 52 and the pressing buckle die 53 with the stamping die 4. The safety type bag buckle machine provided by the embodiment is additionally provided with a controller 6 and two capacitive sensors 7 (the capacitive sensor has one signal port and two sensing electrodes) on this basis. The connection between the workbench 2 and the driving end of the driving motor 3 and the connection between the stamping die 4 and the rack 1 are both insulated connections (that is, the connection portions of the two are provided with insulating members). One of the capacitive sensors 7 is installed on the stamping die 4 (the two sensing electrodes of the capacitive sensor can be welded on the stamping die by means of tin welding, and form two electrically connected points which are spaced apart). The capacitive sensor is used to sense whether the capacitance value of the stamping die 4 changes. The other capacitive sensor 7 is installed on the workbench 2 (the two sensing electrodes of the capacitive sensor can be welded on the workbench by means of tin welding, and form two electrically connected points which are spaced apart). The capacitive sensor is used to sense whether the capacitance value of the workbench 2 changes. The stamping die, the driving motor and the two capacitive sensors 7 are all in electrical connection with the controller 6. By insulating the stamping die and the workbench from the rack respectively, and by setting the controller and the capacitive sensors, and by corresponding one capacitive sensor to the stamping die and the workbench respectively, when a person touches the workbench or the stamping die, the corresponding capacitive sensor will monitor a relatively large change in the capacitance value, and will transmit the signal to the controller at the same time. The controller controls the running state of the bag buckle machine (that is, controls the running state of the driving motor and the stamping die). If a person touches the workbench and / or the stamping die, the controller receives the signal of the corresponding capacitive sensor at this time, and controls the bag buckle machine to stop running (the driving motor stops, and the stamping die stops or retreats to reset), so as to avoid causing harm to the operator.

[0032] In the above technical solution, the controller 6 is installed on the rack 1, and the two capacitive sensors 7 are respectively in electrical connection with the controller 6 through flexible wires 8 (two flexible wires are represented by the two dashed lines), so as to provide a space activity allowance for the workbench and the stamping die. Figure 1 In the above technical solution, the controller 6 is installed on the rack 1, and the two capacitive sensors 7 are respectively in electrical connection with the controller 6 through flexible wires 8 (two flexible wires are represented by the two dashed lines), so as to provide a space activity allowance for the workbench and the stamping die.

[0034] Since the stamping die, the workbench, the upper buckle die 51, the falling buckle die 52 and the pressing buckle die 53 are all metal parts, and the workbench, the upper buckle die 51, the falling buckle die 52 and the pressing buckle die 53 can be regarded as a whole (when a person touches the upper buckle die 51, the falling buckle die 52 and the pressing buckle die 53, it is equivalent to touching the workbench), therefore, the two sensing electrodes corresponding to the capacitive sensor on the stamping die only need to be electrically connected with any two points on the stamping die, and similarly, the two sensing electrodes of the capacitive sensor on the workbench only need to be electrically connected with any two points on the workbench.

[0035] The controller in the embodiment can adopt an arm series single-chip microcomputer.

[0037] The bolt passes through the two connecting holes 222, and at least one nut is threadedly connected at the threaded end of the bolt.

[0038] For details, see Figure 2 and Figure 3As shown, the mounting positions of the upper buckling die, the falling buckling die and the pressing buckling die on the upper end of the workbench in the embodiment are distributed at intervals (specifically, distributed on the same circle, and the circle is coincided with the center of the mounting hole, so that when the workbench rotates, the moving tracks of the upper buckling die, the falling buckling die and the pressing buckling die are coincided, and the punch of the stamping die is just aligned with the tracks, so that when the workbench rotates, the upper buckling die, the falling buckling die and the pressing buckling die can be selectively aligned with the stamping die.
