Description

Technical Field

[0001] This utility model relates to the field of mechanical devices, specifically to a high-speed suction and discharge plate device for an aluminum-plastic machine. Background Technology

[0002] In the production and packaging process of aluminum foil blister packs for pharmaceuticals, a suction and release device on an aluminum-plastic packaging machine is often used for transfer. This device uses a suction cup connected to an air pump to grip and move the aluminum foil blister pack, and switches to air blowing to release it when needed. Existing suction and release devices are typically simple single-tube structures, switching between suction and release modes by directly adjusting the state of the pump connected to the suction cup. The disadvantage of this type of equipment is that the switching frequency is not high enough to meet the demands of high-speed production. Utility Model Content

[0003] Therefore, in order to overcome the problem of insufficient switching frequency of existing suction and discharge plate devices, which easily leads to misalignment, this invention designs a high-speed suction and discharge plate device for plastic injection molding machines. This device uses a high-frequency solenoid valve and a vacuum valve in conjunction to achieve high-speed switching of suction and discharge modes.

[0004] This device consists of a gas source, a high-frequency solenoid valve, a vacuum generator, a suction cup, a first pressure reducing valve, and a second pressure reducing valve. The gas source is connected to the first interface of the high-frequency solenoid valve and the vacuum generator through branch pipelines. The first pressure reducing valve is located on the branch pipeline connecting the gas source and the high-frequency solenoid valve. The second pressure reducing valve is located on the branch pipeline connecting the gas source and the vacuum generator. The vacuum generator is connected to the third interface of the high-frequency solenoid valve through a pipeline. The suction cup is connected to the second interface of the high-frequency solenoid valve through a pipeline.

[0005] The high-frequency solenoid valve can quickly switch the connection modes of each interface when energized. When the first interface is connected to the second interface, the third interface is disconnected, and the system is in air blowing mode. The airflow comes from the air source through the first pressure reducing valve to the suction cup, at which time the aluminum foil tablet is released under the action of the airflow. When the second interface is connected to the third interface, the pipeline is switched, the first interface is disconnected, and the pipeline that generates negative pressure through the vacuum generator is connected to the suction cup. At this time, the aluminum foil tablet is picked up by the suction cup under the action of air pressure.

[0006] The suction cup is a component used to grip aluminum foil blister packs, and it is mounted on the moving mechanism of the aluminum-plastic machine. When the high-frequency solenoid valve is in the position where the second and third interfaces are connected, the suction cup opening is under negative pressure, the blister pack is gripped by the suction cup, and it is transferred as the suction cup moves.

[0007] Furthermore, the first pressure-reducing valve operates during the blowing process to regulate the air pressure intensity; its setting can be adjusted arbitrarily as needed. The second pressure-reducing valve operates during the suction process to regulate the vacuum level; its setting can also be adjusted arbitrarily as needed.

[0008] Beneficial effects: This high-speed suction and discharge plate device for aluminum-plastic machines works in conjunction with a high-frequency solenoid valve and a vacuum valve to achieve high-speed switching of suction and discharge modes. It has the advantages of rapid switching, adjustable air pressure, and simple structure. Attached Figure Description

Detailed Implementation

[0012] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings of the structural schematic diagram of this utility model. The following embodiments are only used to illustrate the technical solutions of this utility model more clearly, and are therefore only examples, and cannot be used to limit the protection scope of this utility model.

[0013] The device provided by the present invention consists of a gas source 1, a high-frequency solenoid valve 2, a vacuum generator 3, a suction cup 4, a first pressure reducing valve 5, and a second pressure reducing valve 6. The gas source 1 is connected to the first interface 201 of the high-frequency solenoid valve 2 and the vacuum generator 3 through branch pipelines. The first pressure reducing valve 5 is installed on the branch pipeline connecting the gas source 1 and the high-frequency solenoid valve 2. The second pressure reducing valve 6 is installed on the branch pipeline connecting the gas source 1 and the vacuum generator 3. The vacuum generator 3 is connected to the third interface 203 of the high-frequency solenoid valve 2 through a pipeline. The suction cup 4 is connected to the second interface 202 of the high-frequency solenoid valve 2 through a pipeline.

[0014] When the device is operating, the states of the first pressure reducing valve 5 and the second pressure reducing valve 6 are preset according to the required air pressure. The high-frequency solenoid valve 2 is energized, switching the connection mode of each interface. When it is necessary to grab the aluminum foil blister pack, the high-frequency solenoid valve 2 switches to the mode of the second interface 202 and the third interface 203, the first interface 201 is disconnected, the vacuum generator 3 works, and negative pressure is generated in the pipeline connecting the vacuum generator 3 and the suction cup 4. At this time, the aluminum foil blister pack is sucked up under the action of air pressure. The moving mechanism of the aluminum-plastic machine drives the suction cup 4 to move and move the blister pack to the target position. Then, the high-frequency solenoid valve 2 switches to the mode of connecting the first interface 201 and the second interface 202, and the third interface 203 is disconnected. At this time, the system pipeline switches to the blowing mode. The airflow from the air source 1 passes through the first pressure reducing valve 5 to the suction cup 4. At this time, the aluminum foil blister pack is released under the action of positive pressure airflow, completing the entire movement process of the blister pack.
