Description

Technical Field

[0001] This application relates to the field of coated paper bag processing, and more specifically, to a biodegradable coated paper bag forming machine. Background Technology

[0002] Paper-based composite packaging materials have become an important alternative to traditional plastic packaging due to their biodegradability. Among them, the application of bio-based biodegradable materials, such as polylactic acid (PLA), in the production of coated paper provides the packaging industry with a solution that combines functionality and environmental protection.

[0003] In the production process of coated paper bags, a coating layer (biodegradable resin, such as PLA or PBAT) needs to be laminated onto the surface of the substrate (kraft paper or food-grade paper). However, during the forming process of coated paper bags, static electricity accumulates on the surfaces of the substrate and the coating as the substrate and the coating are conveyed. Static electricity easily attracts dust and other impurities in the air, resulting in black spots and impurities on the surface of the produced coated paper. In addition, airborne particles (diameter > 5μm) are easily attracted by static electricity and form bumps and bubbles in the coating layer, which reduces the waterproofness of the paper bag and lowers the quality of the paper bag. Therefore, this application proposes a biodegradable coated paper bag forming machine. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a biodegradable coated paper bag forming machine, including a processing table. A pressing mechanism is provided on the processing table. Vertical arms are vertically arranged on both sides of one end of the processing table. A base material roller and a coating material roller are horizontally rotatably mounted between a pair of vertical arms. The substrate on the base material roller and the coating on the coating material roller are spread out and pressed together by the pressing mechanism to form coated paper. An ionizer is horizontally fixed between the pair of vertical arms. The ionizer is located between the base material roller and the coating material roller, and blows ion air between the substrate and the coating on the base material roller and the coating material roller.

[0006] Furthermore, the calendering mechanism includes a bottom shell fixed to the upper surface of the processing table and a top shell disposed above the bottom shell. Multiple pairs of calendering rollers are rotatably mounted on opposite sides of the top and bottom shells, and a calendering motor is mounted on the end wall of the bottom shell. The calendering motor drives one of the calendering rollers to rotate.

[0007] Furthermore, a fixing frame is fixed at the position corresponding to the bottom shell on the processing table. The fixing frame is erected above the bottom shell and the top shell. A hydraulic push rod is vertically installed on the top wall of the fixing frame. The telescopic end of the hydraulic push rod passes through the top wall of the fixing frame and is connected to the top shell.

[0008] Furthermore, a guide rod is vertically and movably inserted through the top wall of the fixed frame, and the bottom end of the guide rod is fixedly connected to the top shell.

[0009] Furthermore, two fixing plates are vertically fixed on both sides of the upper surface of the processing table. The fixing plates are located on the side of the stretching mechanism facing the vertical arm. Two guide rollers are horizontally rotatably installed between the pair of fixing plates, and the two guide rollers are distributed vertically.

[0010] Furthermore, a drying chamber is provided on the upper surface of the processing table away from the vertical arm, and an air inlet is provided on the top wall of the drying chamber, with an electric heating wire installed inside the air inlet.

[0011] Furthermore, an air outlet is provided on the side wall of the drying oven, a fan is installed inside the air outlet, and a mesh is provided at the end of both the air outlet and the air inlet facing the outside of the drying oven.

[0012] Furthermore, the processing table has horizontally fixed support arms on both sides facing one end of the vertical arm, and a pair of vertical arms are respectively vertically fixed to the ends of the pair of support arms. The top of the vertical arm is provided with a first slot for the coating material roller to be rotatably embedded, and the side wall of the vertical arm is provided with a second slot for the base material roller to be rotatably embedded. A pair of feeding motors are also mounted on the vertical arm, and the pair of feeding motors are detachably connected to the shafts of the coating material roller and the base material roller respectively.

[0013] The beneficial effects of this application are as follows:

[0014] Through the setting of the calendering mechanism and the drying box, the substrate on the base material roller and the coating on the coating material roller unfold together and pass through a pair of guide rollers, between the bottom shell and the top shell, and through the drying box, and are continuously tractioned to the next process. The feeding motor controls the base material roller and the coating material roller to release the substrate and coating at a uniform speed. During this process, multiple pairs of calendering rollers between the bottom shell and the top shell calender and laminate the substrate and coating to form coated paper. When the coated paper after calendering and lamination passes through the drying box, it can be dried and shaped by the heating wire, which accelerates the curing of the coating layer, eliminates internal stress, and prevents deformation in subsequent processing. The fan is started to exhaust air out of the drying box, which can increase the air circulation speed in the drying box and improve the drying efficiency of the coated paper. It integrates feeding, guiding, calendering and lamination and drying and shaping into one unit. The structure is compact and occupies a small area, which provides convenience for the processing of coated paper.

[0015] By setting up ion air bars, before the substrate on the base material roller and the coating on the coating material roller are rolled and laminated, the ion air bars blow ion air carrying a large number of negative ions between the substrate and the coating. This can neutralize the static charge on the composite surface of the substrate and the coating, and minimize the problems of the substrate and the coating shifting, wrinkling, and dust adsorption during the transportation process, which affect the final quality of the coated paper.

The calendering motor 12 drives one of the calendering rollers 11 to rotate. The substrate on the base material roller 3 and the coating on the coating material roller 4 unfold together and pass through the bottom shell 9 and the top shell 10 and are transported to the next process for continuous traction. During this process, multiple pairs of calendering rollers 11 between the bottom shell 9 and the top shell 10 calender and laminate the substrate and coating to form a coated paper. The calendering motor 12 drives the corresponding calendering roller 11 to rotate, which can assist in the transport of the coated paper.

[0032] In this embodiment, a fixing frame 13 is fixed on the processing table 1 at a position corresponding to the bottom shell 9. The fixing frame 13 is erected above the bottom shell 9 and the top shell 10. A hydraulic push rod 14 is vertically installed on the top wall of the fixing frame 13, and the telescopic end of the hydraulic push rod 14 passes through the top wall of the fixing frame 13 and is connected to the top shell 10. A guide rod 15 is vertically and movably installed on the top wall of the fixing frame 13, and the bottom end of the guide rod 15 is fixedly connected to the top shell 10. By activating the hydraulic push rod 14, the top shell 10 can be raised and lowered, facilitating the initial substrate and coating to pass between the bottom shell 9 and the top shell 10.

[0033] In this embodiment, two fixing plates 16 are vertically fixed on both sides of the upper surface of the processing table 1. The fixing plates 16 are located on the side of the pressing mechanism 7 facing the vertical arm 2. Two guide rollers 6 are horizontally rotatably installed between the pair of fixing plates 16. The two guide rollers 6 are distributed vertically. The substrate and the coating pass through the pair of fixing plates 16. The pair of fixing plates 16 can guide the substrate and the coating. The processing table 1 has horizontally fixed support arms 25 on both sides facing the vertical arm 2. A pair of vertical arms 2 are respectively vertically fixed at the ends of the pair of support arms 25. The top of the vertical arm 2 is provided with a first slot 17 for the coating material roller 4 to be rotatably embedded. The side wall of the vertical arm 2 is provided with a second slot 18 for the base material roller 3 to be rotatably embedded, which facilitates the replacement of the base material roller 3 and the coating material roller 4. A pair of feeding motors 19 are also installed on the vertical arm 2. The pair of feeding motors 19 are detachably connected to the shafts of the coating material roller 4 and the base material roller 3 respectively. The feeding motors 19 are used to control the base material roller 3 and the coating material roller 4 to release the substrate and coating material at a uniform speed.

[0034] In a further embodiment, a drying chamber 8 is provided on the upper surface of the processing table 1 away from the vertical arm 2.

An air outlet 22 is provided on the side wall of the drying chamber 8, and a fan 23 is installed inside the air outlet 22. A mesh 24 is provided at the ends of both the air outlet 22 and the air inlet 20 facing outwards from the drying chamber 8. The coated paper, after being laminated by multiple pairs of calendering rollers 11, is conveyed through the drying chamber 8 and dried and shaped by the heating wire 21. This accelerates the curing of the coated layer, eliminates internal stress, and prevents deformation during subsequent processing. Furthermore, the fan 23 exhausts air outwards from the drying chamber 8, increasing the airflow speed within the drying chamber 8 and improving the drying efficiency of the coated paper.

[0035] In a further embodiment, an ion air bar 5 is horizontally fixed between a pair of vertical arms 2. The ion air bar 5 is located between the base material roller 3 and the coating material roller 4. The ion air bar 5 blows ion air between the substrate and the coating film that are being rolled and laminated on the base material roller 3 and the coating material roller 4. Before the substrate on the base material roller 3 and the coating film on the coating material roller 4 are rolled and laminated, the ion air bar 5 blows ion air with a large number of negative ions between the substrate and the coating film to neutralize the static charge on the composite surface of the substrate and the coating film. This avoids as much as possible the problem of the substrate and the coating film shifting, wrinkling, and dust adsorption during the transportation process due to static electricity, which affects the final quality of the coated paper. The ion air bar 5 is connected to the air compression equipment and the power supply in advance.

[0036] During use, the substrate on the base material roller 3 and the coating on the coating roller 4 are spread out and pass through a pair of guide rollers 6, the bottom shell 9 and the top shell 10, and the drying box 8 and are transported to the next process for continuous traction. The feeding motor 19 controls the base material roller 3 and the coating roller 4 to release the substrate and coating at a uniform speed. During this process, multiple pairs of calendering rollers 11 between the bottom shell 9 and the top shell 10 calender and laminate the substrate and coating to form a coated paper. The calendering motor 12 drives the corresponding calendering roller 11 to rotate, which can assist in the transportation of the coated paper. The heating wire 21 is energized. When the coated paper after calendering and lamination passes through the drying box 8, it can be dried and shaped by the heating wire 21, which accelerates the curing of the coating layer, eliminates internal stress, and prevents deformation in subsequent processing. The fan 23 is started to exhaust air out of the drying box 8, which can increase the air circulation speed in the drying box 8 and improve the drying efficiency of the coated paper. Furthermore, before the substrate on the base material roller 3 and the coating on the coating material roller 4 are rolled and laminated, the ion air bar 5 blows an ion air carrying a large number of negative ions between the substrate and the coating to neutralize the static charge on the composite surface of the substrate and the coating, so as to avoid the problems of the substrate and the coating shifting, wrinkling and dust adsorption affecting the final quality of the coated paper due to static electricity during the transportation process.
