This structure is used to guide the lifting frame 16 and connect it with the toothed belt 20, thereby ensuring the stable lifting and lowering of the lifting frame 16.
[0034] Installation method and operating principle: First, connect the conveyor frame 1, which is equipped with the bottle-pushing cylinder 9 and the conveyor belt 7, to one side of the support base 2. During the process of installing the upright plate 3 on the upper surface of the support base 2, install the upper guide roller 29 between the two upright plates 3. At the same time, mate the guide blocks 25 at both ends of the lifting frame 16 with the guide grooves 23 of the upright plate 3. At this time, the connecting parts 24 at both ends of the lifting frame 16 also pass through the guide grooves 23. Pass the shaft 21 through the two upright plates 3, and install the upper toothed pulleys 19 at both ends of the shaft 21. Install the two lower toothed pulleys 18 on the outside of the two upright plates 3 respectively through the wheel axle, and connect the upper toothed pulley 19 and the lower toothed pulley 18 on the same side with the toothed belt 20 respectively. At the same time, install the first motor 22 on the outer surface of the motor base, and connect the output shaft of the first motor 22 to one end of the shaft 21 through the coupling. Connect the connecting parts 24 of the lifting frame 16 with the toothed belt 20 through bolts and nuts. Then, install the heating cutter 17 below the lifting frame 16 through the connecting rod. The connecting beam 6 and connecting plate 5 are installed between the two upright plates 3, and the vertical cylinder 11 is installed on the upper surface of the connecting plate 5. The upper pressure plate 13, which is connected to the first baffle 14, is connected to the piston rod of the vertical cylinder 11. Here, the vertical cylinder 11 adopts a double piston structure. The two side cylinders 12 are installed on the outside of the upright plate 3, and the side pressure plate 15 is connected to the piston rod of the side cylinder 12 by bolts to complete the installation. In use, the two rolls of film are supported on the upper film support plate 26 and the lower film support plate 28 respectively by the support shaft. The two rolls of film are turned by the upper guide roller 29 and the lower guide roller 30 respectively, and then meet on the upper surface of the support base 2. At the beginning of processing, the ends of the two rolls of film are stacked. The first motor 22 drives the shaft 21 to rotate, which drives the toothed belt 20 to rotate through the cooperation of the upper toothed pulley 19 and the lower toothed pulley 18. This drives the lifting frame 16 and the heating cutter 17 to press down, so that the two rolls of film are connected. The piston rod of the vertical cylinder 11 drives the upper pressure plate 13 to descend, and the height of the upper pressure plate 13 is higher than the height of the bottled beverage. The bottom of the first baffle 14 is aligned with the middle of the bottled beverage. The bottled beverage moves along the conveyor belt 7 and is diverted by the channel divider 39. The limit cylinder 37 drives the third baffle 38 to rise, and the bottled beverage moves forward along the conveyor belt 7. After passing a predetermined number of bottles, the third baffle 38 descends and blocks the bottles behind. When the bottled beverage passing through the gantry 36 moves to the middle position of the push plate 10 (based on the conveyor belt speed and movement time logic calculation), the second motor 33 stops, the conveyor belt 7 stops rotating, and the bottle pusher cylinder 9 drives the push plate 10 forward, pushing a group of bottled beverages from the conveyor belt 7 to the support seat 2. The two rolls of film are located at the lower and upper ends of the bottled beverages, respectively, and the front bottled beverage is limited by the first baffle 14.At this time, the piston rod of the vertical cylinder 11 drives the upper pressure plate 13 to descend and press the upper pressure plate 13 onto the top of the bottled beverage. The piston rod of the side cylinder 12 drives the side pressure plate 15 to press the bottled beverage on both sides. At this time, through the push plate 10, the upper pressure plate 13 and the two side pressure plates 15, the bottled beverage is arranged in a rectangular array, as shown. Figure 5 As shown. Next, the piston rod of the bottle-pushing cylinder 9 drives the push plate 10 to retract to the end, and the first motor 22 drives the heated cutter 17 to press down (the heated cutter 17 has a built-in heating element at the bottom to heat the cutter, so that it can instantly melt the edge of the heat shrink film and stick it together when cutting, thereby achieving cutting and sealing), wrapping the upper film around the back of the bottled beverage. The heated cutter 17 heats up instantly, causing the two films to melt, stick together and cut, and then the heated cutter 17 rises. The piston rods of the vertical cylinder 11 and the side cylinder 12 are both retracted, and the upper pressure plate 13 and the side pressure plate 15 leave the bottled beverage. At this time, the height of the bottom of the first baffle 14 is higher than the height of the bottled beverage. Then, the second motor 33 restarts, the third baffle 38 rises, and the conveyor belt 7 continues to move the bottled beverages forward. Repeating the above steps, the following bottled beverages, after being wrapped in film, push the preceding group out of the support seat 2. As the first group of wrapped bottled beverages leaves the support seat 2, it moves onto the conveyor belt of the film heating and shrinking machine and leaves the support seat 2. At this time, the piston rod of the vertical cylinder 11 descends and, through the first baffle 14, blocks the following group of bottled beverages again. The above steps are repeated to wrap the bottled beverages. This utility model has a reasonable structure. The piston rod of the vertical cylinder 11 is equipped with an upper pressure plate 13. A first baffle 14 is set on the side of the pressure plate away from the conveyor frame 1. A side cylinder 12 is set on the outside of the upright plate 3. The piston rod of the side cylinder 12 is equipped with a side pressure plate 15. When the bottle pusher cylinder 9 pushes the material, the bottled beverage is positioned on six sides by the cooperation of an upper pressure plate 13, two side pressure plates 15, a pusher plate 10, a first baffle 14 and a support seat 2. This ensures that the bottled beverage is arranged in a rectangular row during the wrapping process, and there will be no uneven bottles during the packaging process. This greatly improves the wrapping effect and the quality of product packaging.
