Wherein, the driven synchronous wheels 49 in the driven synchronous wheel set have the same radius, and the driving wheels 35 corresponding to the driven synchronous wheels 49 have the same radius.

In this embodiment, the servo motor drives the active transmission synchronous wheel to rotate counterclockwise. Due to the way that the double-sided toothed synchronous belt is wound in the driven synchronous wheel set, the two sets of driven synchronous wheels are driven by the double-sided toothed synchronous belt. One of them rotates clockwise, and the other rotates counterclockwise, thereby driving the transmission belt on the correspondingly connected driving wheel to rotate synchronously and reversely.

The setting of the synchronous transmission mechanism realizes the synchronous rotation of the driven synchronous wheel under the drive of the active transmission synchronous wheel through the cooperation of the active transmission synchronous wheel, the driven synchronous wheel and the double-sided tooth synchronous belt. The drive wheels connected and rotated synchronously are output, so as to realize the synchronous reverse rotation of the conveyor belt connected with the corresponding driving wheels to meet the requirements of feeding and discharging, and the synchronization between the driven synchronous wheels is extremely high.

As shown in Figure 15, the heat sealing mechanism includes a silicone strip 54 and a heat sealing strip 55 electrically connected to the heating transformer, and the heat sealing strip 55 is connected to the support guide of the support frame 57 on the moving plate 32 through the fixed mounting seat 56. The rod 58 is fixedly connected, and the silicone strip 54 is slidably connected with the support guide rod 58 of the support frame 57 through a sliding mounting seat 59. An elastic member is arranged between the fixed mounting seat 56 and the sliding mounting seat 59, and the moving On the plate 32, the corresponding part of the silicone strip 54 is provided with a groove, and an airbag connected to the vacuum pump is arranged in the groove. The airbag is pressed against the silica gel strip 54 in the inflated state, and the airbag is exhausted after the heat sealing is completed. , the sliding mounting seat drives the silicone strip to reset under the action of the elastic component.

When the fully automatic vacuum packaging machine is in use, the two conveyor belts are first opened by the manipulator to make it in the feeding state. After the packaging bag enters between the two conveyor belts, it is transported backward under the action of the synchronous reverse rotation of the conveyor belts. After the number of packaging bags reaches the required value, the feeding end of the conveyor belt is closed, and the conveyor belt stops rotating; the driving motor connected to the screw is started, and the moving sliding sleeve matched with the screw thread is driven to move, so as to drive the moving plate to move to the vacuum chamber on the corresponding side And form a closed space with the vacuum chamber respectively, then start the vacuum pump, and pump out the gas in the closed space formed between the vacuum chamber and the moving plate through the pipeline connected with the vacuum chamber. When the set air pressure is reached, the vacuum pump stops working At this time, the heat-sealing strip is heated by the heating transformer, and the vacuum pump injects gas into the airbag to cause the airbag to expand rapidly. The silicone strip is pushed to the corresponding heat-sealing strip under the push action of the airbag in the inflated state, and the food bag is heat-sealed, thus Realize vacuuming and heat sealing of food bags.

While vacuuming and heat-sealing one side, the conveying device on the other side of the moving plate outputs the packaged food bags and inputs the food bags to be sealed. When this side is ready, the other side’s pumping The process of vacuum and heat sealing is also over. At this time, the drive motor drives the screw to reverse, so that the moving plate moves to the vacuum chamber on the other side, and repeats the above steps, so as to realize the alternate operation of two groups of vacuum pumping and heat sealing, which greatly improves the The efficiency of production and processing.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range. the
