When pressing a relatively thin packaging bag, due to the unsatisfactory pressing force of the rolling column, air is still likely to enter the packaging bag, resulting in bubbles, etc., increasing the production probability of defective products.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A conveying device for a packaging bag production line, including a transport rack, both inner walls of the transport rack are fixedly connected with a conveyor belt, one outer wall of the transport rack is fixedly connected with an adjustment rack, the top outer wall of the adjustment rack is fixedly connected with a support frame, and a rectifying mechanism is arranged on the support frame.

[0014] The present utility model has the following beneficial effects:

[0015] 1. In the utility model, by setting structures such as sliding plates, rotating rods, and torsion springs, continuous pressure is applied to the rolling column to make the rolling force of packaging bags of different thicknesses ideal, reduce the air bubbles inside, and improve the situation that when the packaging bags are placed on the conveyor belt for transportation, the surface of the packaging bags is simply pressed by the weight of the rolling column itself. When rolling thin packaging bags, air may still easily enter the packaging bags, bubbles may appear, etc., due to the unsatisfactory pressing force of the rolling column, thereby increasing the probability of producing defective products. At the same time, when pressing the packaging bags, the bonded packaging bags are scraped off to prevent the packaging bags from being rolled into the interior of the rolling column to cause mechanical damage and the packaging bags from breaking to affect production efficiency.

[0016] 2. In the utility model, by setting up T-shaped frames, handles, brush plates and other structures, the surface of the packaging bags is wiped and cleaned to a certain extent, thereby improving the problem of dirt remaining on the surface of the packaging bags during transportation, which affects the quality of subsequent production and processing. At the same time, the brush plates can be easily disassembled, cleaned and replaced, thereby improving the problem of dirt remaining on the brushes themselves and aging after long-term use, which makes cleaning and maintenance inconvenient.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a conveying device for a packaging bag production line, including a transport rack 1. The inner walls on both sides of the transport rack 1 are fixedly connected with a transport belt 2. One outer wall of the transport rack 1 is fixedly connected with an adjustment rack 3. By setting the adjustment rack 3 to cooperate with the support frame 4, the adjustment rack 3 drives the support frame 4 to perform a certain fine-tuning lift. The above structure is prior art and will not be described in detail here. The top outer wall of the adjustment rack 3 is fixedly connected with a support frame 4. A rectifying mechanism 6 is arranged on the support frame 4. The rectifying mechanism 6 includes an auxiliary mechanism 7. The rectifying mechanism 6 includes a sliding plate 61. The sliding plate 61 is slidably connected to the inner walls on both sides of the support frame 4. The top outer wall of the sliding plate 61 is fixedly connected with a spring damper 62. By setting the spring damper 62 to continuously generate a thrust on the rolling column 63, the rolling column 63 presses the packaging bag more tightly, reducing the air in the packaging bag. The bottom inner wall of the sliding plate 61 is rotatably connected with a rolling column 63. The inner walls on both sides of the sliding plate 61 are rotatably connected with a rotating rod 64 through bearings. A torsion spring 65 is fixedly connected to the rotating rod 64. An arc-shaped scraper 66 is fixedly connected to the rotating rod 64.

[0025] Referring to Figures 2 - 4 , one end of the spring damper 62 away from the sliding plate 61 is fixedly connected to the top inner wall of the support frame 4. The rolling column 63 is rollingly connected to the top outer wall of the transport belt 2. One end of the torsion spring 65 away from the rotating rod 64 is fixedly connected to the inner wall on one side of the sliding plate 61. By setting the torsion spring 65, the rotating rod 64 rotates to generate a flexible thrust between the arc-shaped scraper 66 and the rolling column 63, which is likely to cause the packaging bag to adhere and wind around the rolling column 63 when being pressed, resulting in damage to the rectifying mechanism 6 and affecting the production efficiency of the packaging bag. The arc-shaped scraper 66 is slidably connected to the side outer wall of the rolling column 63. A wear-resistant pad is fixedly connected to the side outer wall of the arc-shaped scraper 66 close to the rolling column 63. By setting the wear-resistant pad, the wear caused by the long-term sliding of the arc-shaped scraper 66 on the rolling column 63 is reduced. One outer wall of the support frame 4 is fixedly connected with a partition strip 5. The partition strip 5 is slidably connected to the top outer wall of the transport belt 2. By setting the partition strip 5, two packaging bags are separately conveyed while the transport belt 2 moves, so that the rolling column 63 presses and processes the two packaging bags at the same time, improving the working production efficiency to a certain extent.

[0026] Referring to Figures 3 - 4, the auxiliary mechanism 7 includes an installation groove 71 which is opened on the inner bottom wall of the sliding plate 61. The two inner walls of the installation groove 71 are slidably connected with a T-shaped frame 72. One side outer wall of the T-shaped frame 72 away from the sliding plate 61 is fixedly connected with a handle 73. By setting the handle 73, it is convenient for personnel to disassemble and assemble the brush plate 74. One inner wall of the T-shaped frame 72 is clamped with a brush plate 74. By setting the brush plate 74, it can clean the surface dust and dirt of the packaging bag during transportation to a certain extent, reducing the dirt on the packaging bag and affecting the production quality. An indication mark is opened on one side outer wall of the handle 73. By setting the indication mark, it can prompt the operation method. The brush plate 74 is slidably connected to the top outer wall of the conveyor belt 2.

[0027] Working principle: By starting the transport rack 1, the conveyor belt 2 moves. The movement of the conveyor belt 2 drives the packaging bag to be divided into two sides by the partition strip plate 5, and then transports it to the lower part of the rolling column 63 to contact the packaging bag, so that the rolling column 63 moves by squeezing the sliding plate 61 according to the different thicknesses of the packaging bag. Under the action of the spring damper 62, the sliding plate 61 continuously generates a thrust on the rolling column 63, making the packaging bag more forceful during rolling and reducing the air bubbles inside. At the same time, when the pressing force of the rolling column 63 is relatively large, the packaging bag is easily adhered to the rolling column 63. When the packaging bag is adhered, it contacts the arc-shaped scraper 66, so that the adhered packaging bag is scraped off. At the same time, before the packaging bag is rolled, it passes through the brush plate 74, so that the brush plate 74 wipes and cleans the surface of the packaging bag to a certain extent, reducing the dirt for the subsequent production and processing of the packaging bag.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
