Description

Technical Field

[0001] The utility model relates to the field of plastic film production and processing, in particular to a packaging film blow molding bubble guiding and stabilizing device. Background Art

[0002] Blow molding machines are commonly used in the production of plastic packaging film. They operate by using an extruder to melt the plastic material into a molten phase at high temperatures. This is then directed to the blow molding machine head, where an air ring blows the molten plastic into a tubular film bubble. Because the film is very soft, the bubble is prone to shaking during the blow molding process, which can even result in product failure. To address this, a bubble stabilization rack is installed above the extrusion port of the film blow molding machine. Traditional bubble stabilization racks are typically fixed and cannot be adjusted vertically. This results in the rack being unable to adjust to the location of the film bubble experiencing the greatest shaking during blow molding. Utility Model Content

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 and 2As shown, this embodiment discloses a packaging film blown film bubble guiding and stabilizing device, including a bubble stabilizing device 1, which is arranged on the front of the lifting seat plate 2, and a frame 3 is provided on the back of the lifting seat plate 2. The frame 3 is provided with two guide rails 4 in the vertical direction on the side close to the lifting seat plate 2, and a slider 5 is provided on the guide rail 4, and the slider 5 is fixed to the back of the lifting seat plate 2.

[0021] The frame 3 is provided with a lifting reduction motor 6 and a first sprocket 7. The housing of the lifting reduction motor 6 is fixed to the frame 3. The first sprocket 7 is connected to the frame 3 via a sprocket seat. The lifting reduction motor 6 and the first sprocket 7 are connected by a first ring-shaped closed chain 8. One link of the first chain 8 is fixed to the lifting seat 2. The lifting reduction motor 6 drives the first chain 8 to operate, thereby driving the lifting seat 2 to move up and down.

[0022] It should be noted that after the film bubble emerges from the bubble stabilization device 1, it needs to be guided by a herringbone plate. The herringbone plate needs to be connected to the ground via a herringbone plate support frame. The frame 3 in this embodiment can be fixed to the herringbone plate support frame. Multiple distance sensors are installed around the film bubble. The distance sensors feed monitoring signals back to the controller, which controls the rotation of the lifting and reducing motor 6.

[0023] like Figure 3 As shown, the bubble stabilizing device 1 includes an upper ring plate 101 and a lower ring plate 102. Both the upper ring plate 101 and the lower ring plate 102 are provided with an L-shaped connecting plate 10, which is connected to the front surface of the lifting base plate 2 via bolts. A plurality of fixing rods 103 are provided between the upper ring plate 101 and the lower ring plate 102. The ends of the fixing rods 103 are respectively fixed to the upper ring plate 101 and the lower ring plate 102. A rotating rod 104 is provided between adjacent fixing rods 103. The ends of the rotating rod 104 are respectively rotatably connected to the upper ring plate 101 and the lower ring plate 102. The rotating rod 104 is provided with a plurality of stabilizing cross bars 105, and the stabilizing cross bars 105 are covered with rolling sleeves 106.

[0024] Stabilizing crossbars 105 between rotating rods 104 form a regular polygon, through which the film bubble passes. Rolling sleeves 106 on stabilizing crossbars 105 rest against the film bubble, and the regular polygon changes size as the rotating rods 104 rotate to accommodate film bubbles of different sizes. In this embodiment, the rotation of each rotating rod 104 is controlled by a rotary drive assembly 9, which is mounted on the upper ring plate 101.

[0025] The rotary drive assembly 9 includes a second sprocket 901 mounted and fixed on the upper end of the rotating rod 104, and each second sprocket 901 is connected together in sequence through a closed second chain 902; a third sprocket 903 is provided above one of the second sprockets 901, and the third sprocket 903 is also mounted and fixed on the rotating rod 104. The third sprocket 903 is connected to the rotary reduction motor 905 through the third chain 904, and the rotary reduction motor 905 is provided on the upper ring plate 101.

[0026] In this embodiment, a fourth sprocket 906 is provided between two adjacent second sprockets 901. The fourth sprocket 906 is rotatably connected to the upper ring plate 101. The fourth sprocket 906 is located on the inner side of the second chain 902 and is engaged with the second chain 902. The fourth sprocket 906 plays a role of guiding and tightening.
