Description

Technical Field

[0001] This utility model relates to the field of heat sealing packaging machine technology, and in particular to a rotary high-frequency heat sealing packaging device. Background Technology

[0002] A high-frequency heat sealing machine is a type of equipment used for blister packaging. During operation, it primarily utilizes a high-frequency electromagnetic field to cause intense collisions between molecules within the plastic, generating high temperatures to achieve welding and fusion. Specifically, the high-frequency heat sealing machine uses a high-frequency electric field to cause the molecules within the plastic to oscillate, generating heat. Under the influence of this high-frequency electric field, the dielectric material undergoes molecular polarization and aligns according to the direction of the electric field. Because the high-frequency electric field changes direction at an extremely rapid rate, the dielectric material heats up due to dielectric loss.

[0003] In the existing technology, most high-frequency heat sealing machines are dual-station heat sealing machines, that is, the left and right stations work alternately. Operators need to be arranged for each station. The general process is as follows: different products are put into the mold at both stations, then insulating films are placed on them, and the heat-sealed and cut products and waste materials are manually removed from the mold. The process is cumbersome, with high labor costs and low production efficiency. Utility Model Content

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, a rotary high-frequency heat-sealing packaging device includes a base 100, on which a turntable 400 is mounted.

[0031] like Figure 2 As shown, the turntable lifting drive mechanism 600 includes a lifting cylinder 601 fixed on a cylinder mounting plate 604. The driving end of the lifting cylinder 601 is connected to the center of the lower end face of the lifting plate 602. The lower ends of a lifting column 603 are fixedly connected to the four corners of the upper end face of the lifting plate 602, and the upper ends of the four lifting columns 603 are fixedly connected to the four corners of the lower end face of the reducer fixing plate 503.

A lower limit switch 607 is fixed to the side of the reducer fixed plate 503. When the lower limit switch 607 contacts the upper surface of the fixed plate 606, it can trigger the lifting cylinder 601 to stop working.

[0033] like Figure 1As shown, the front of the turntable 400 is a loading / unloading station, where a loading / unloading mechanism 300 is installed. This mechanism 300 can convey paper cards into the heat-sealing mold 200 at the loading / unloading station. It can also convey heat-sealed products from the heat-sealing mold 200 to their corresponding positions. The rear of the turntable 400 is a heat-sealing station, where a high-frequency heat-sealing mechanism 700 is installed. This mechanism 700 can perform heat-sealing processing on the cardboard and plastic boxes within the heat-sealing mold 200.

[0034] like Figure 3 As shown, the high-frequency heat sealing mechanism 700 includes a high-frequency heat sealing mounting frame 701, on which a machine head lifting cylinder 703 is vertically fixed. The drive end of the machine head lifting cylinder 703 is connected to the high-frequency heat sealing machine head 702.

The upper ends of the four lifting guide rods 705 are respectively connected to four guide sleeves 704 and can slide up and down along the guide sleeves 704. The four guide sleeves 704 are fixed on the high-frequency heat sealing mounting frame 701.

[0035] like Figure 3 and Figure 4 As shown, a high-frequency generating mechanism is provided at the rear of the high-frequency heat sealing mounting frame 701, which can output high-frequency current to the high-frequency heat sealing head 702. The high-frequency generating mechanism includes a high-frequency oscillating barrel 706 disposed within the high-frequency heat sealing mounting frame 701, and an electron tube 707 disposed within the high-frequency oscillating barrel 706.

[0036] like Figure 4 As shown, a current regulating component is installed on one side of the high-frequency oscillation barrel 706, which can adjust the magnitude of the high-frequency current. The high-frequency oscillation barrel 706, the electron tube 707, the current regulating component, and the high-frequency heat sealing head 702 are connected in the same circuit.

One end of the regulating screw 734 is threaded onto the fixed plate 733, and the other end is connected to the center position of the regulating plate 736 via a bearing. When the current regulating component is working, the regulating motor 735 drives the regulating screw 734 to rotate. The rotation of the regulating screw 734 causes the first capacitor plate 731 to move back and forth, thereby changing the distance between the first capacitor plate 731 and the second capacitor plate 732, and ultimately regulating the magnitude of the high-frequency current.

A surrounding plate is connected around the upper insulating plate 709, enclosing the components connected to the lower end face of the upper insulating plate 709 to form a protective enclosure.

[0039] like Figure 5 and Figure 6 As shown, a pad 714 is provided below the heating plate 712. During operation, the pad 714 prevents paper from sticking to the lower end face of the heating plate 712.

The lower end of the third rotating shaft 719 is connected to one end of the third cam 728, and the other end of the third cam 728 is connected to the upper surface of the second clamping block mounting plate 727. The lower end of the second clamping block mounting plate 727 is connected to the upper end of two second pad clamping blocks 729. The lower ends of the two second pad clamping blocks 729 are respectively clamped in the arc-shaped slots on the right side of the pad 714. A quick clamp 730 is provided on the second pad clamping block 729, which can clamp one side of the pad 714.

[0041] When the pad mounting mechanism is working, the micro reduction motor 715 drives four rotating shafts to rotate synchronously through the gear belt assembly.
