Description

Technical Field

[0001] This utility model relates to the field of paper-plastic composite bag processing technology, and more specifically to a flattening device for paper-plastic composite bag processing. Background Technology

[0002] Paper-plastic composite bags are made of plastic and kraft paper. The plastic layer is usually made of flat woven fabric with polypropylene (PP) or polyethylene (PE) as the base material, while the kraft paper is made of refined composite special kraft paper. It has the characteristics of high strength, good water resistance and beautiful appearance. It is one of the most popular packaging materials and is widely used in plastic raw materials, cement, feed, chemical, fertilizer and other industries. In the production and processing of paper-plastic composite bags, the plastic packaging bags need to be flattened after lamination to facilitate subsequent printing, sewing and edge gluing of plastic packaging bags.

[0003] The existing technology discloses a flattening device for processing high-barrier nanocomposite film bags, which uses a hot air blower to deliver heat to the inside of the air blowing pipe, where it is diverted by several flow dampers and then sprayed out from the air outlet to slightly heat the pressure roller. This allows the pressure roller to effectively improve the flattening effect of the film bag after being heated by the silicone heating sleeve, avoiding the need for multiple repeated operations to achieve the required flatness. However, this utility model also has the following problems: heating only one side will lead to inconsistent flattening effects on both sides, and the thickness of the composite bag will vary depending on the number and thickness of different film layers. Therefore, a fixed pressure roller cannot be adapted to flatten composite bags of different thicknesses, resulting in poor practicality. Therefore, this utility model proposes a flattening device for processing paper-plastic composite bags. Utility Model Content

[0004] The purpose of this utility model is to provide a flattening device for processing paper-plastic composite bags, which can effectively flatten both sides and can be adapted to flatten paper-plastic composite bags of different thicknesses, making it highly practical.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flattening device for processing paper-plastic composite bags includes a base and support legs. The base has a roll section on both sides of its upper end. Between the roll sections, a flattening section, a limiting section, and an adjusting section are arranged sequentially from left to right on the upper end of the base. Each roll section includes a rotatably mounted inner cylinder. The adjusting section includes a liftable adjusting column. The flattening section includes side plates fixed to both sides of the base. A first horizontal plate and a second horizontal plate are fixedly mounted between the side plates from top to bottom. Several downward pressure rollers are rotatably mounted on one side of the first and second horizontal plates. A liftable upper pressure roller is mounted on the upper end of each downward pressure roller. A hot air structure is provided on the other side of both the first and second horizontal plates.

[0007] By adopting the above technical solution, this utility model has the following advantages:

[0008] The design of the upper and lower pressure rollers in this invention can effectively flatten both sides of the paper-plastic composite bag. The movable design of the upper pressure roller allows the distance between the upper and lower pressure rollers to be adjusted according to the thickness of the paper-plastic composite bag, making it highly practical. The hot air structure in this invention can slightly heat the paper-plastic composite bag, effectively improving the subsequent flattening effect.

A cross plate is fixed to the side of the through hole that is far away from the central plate. A heating wire is fixed to the side of the cross plate that is close to the fan blades. The heating wire is arranged in a circular pattern.

[0013] By adopting the above technical solution, this utility model has the following advantages:

[0014] The second motor in this invention drives the fan blades to rotate, thereby blowing the heat generated by the heating wire onto the paper-plastic composite bag to achieve micro-heating of the paper-plastic composite bag.

[0015] Furthermore, the drum section includes a vertical plate fixedly connected to both sides of the base. Both sides of the inner drum are provided with embedded grooves.

[0018] Furthermore, the latching part includes a cylinder structure. A cylinder structure is fixedly provided on one side of the upright plate near the latching part. The output end of the cylinder structure passes through the upright plate and is fixedly connected to one side of the sub-plate. A panel is rotatably connected to the side of the sub-plate away from the cylinder structure via a rotating shaft. The panel is fixedly connected to the corresponding inner block and the latching block. An inner groove is provided on the upright plate corresponding to the position of the sub-plate. The sub-plate matches the inner groove.

[0019] By adopting the above technical solution, this utility model has the following advantages:

[0020] The cylinder structure of this utility model can drive the sub-plate to move, thereby moving the panel closer to the inner cylinder to fix the inner cylinder, or moving it away from the inner cylinder to separate the inner cylinder.

[0021] Furthermore, the limiting part includes two upright plates fixedly connected to both sides of the upper end of the base, and a limiting post is rotatably connected between the two upright plates.

[0022] By adopting the above technical solution, this utility model has the following advantages:

[0023] The limiting post in this invention serves to restrict the movement path of the paper-plastic composite bag.

[0024] Furthermore, the adjustment unit also includes a vertical plate three fixedly connected to both sides of the upper end of the base. Each of the opposite sides of the vertical plate three is provided with a moving groove, and an adjustment block is embedded in each of the moving grooves.

[0040] Working principle: Before use, in the paper-plastic composite bag lamination process, simply use the inner cylinder 5 as the winding cylinder to wind the laminated paper-plastic composite bag onto the inner cylinder 5. Align the inner groove 501 and slot 502 on one side of the inner cylinder 5 with the inner block 6 and slot 601 and insert them for fixation. Then, start the cylinder structure 28 to drive the auxiliary plate 19 to move towards the inner cylinder 5 until the inner block 6 and slot 601 on the other side are inserted into the corresponding inner groove 501 and slot 502 for fixation. Then, pull one end of the paper-plastic composite bag through the upper end of the adjusting column 15 and the lower end of the limiting column 23, and then pass it between the upper pressure roller 3 and the lower pressure roller 4 to finally fix it onto the corresponding inner cylinder 5. Start the motor 7 to drive the threaded column 701 to rotate, thereby driving the upper pressure roller 3 to move down to match the thickness of the paper-plastic composite bag. The position is determined by starting motor 11, motor 14, and heating wire 24. Motor 11 moves the paper-plastic composite bag to achieve flattening and winding. Starting motor 14 drives the fan blade 801 to rotate, which can heat the heating wire 24 to the paper-plastic composite bag, achieving a micro-heating function. This makes the paper-plastic composite bag flatter and more even. Flattening after micro-heating effectively improves the overall flattening effect and prevents wrinkles. Starting motor 9 can drive the adjusting column 15 to move up and down, thereby adjusting the tightness of the paper-plastic composite bag and effectively preventing wrinkles.
