Description

Technical Field

[0001] This invention relates to the field of packaging bag processing, and more specifically to a packaging bag processing system and processing method. Background Technology

[0002] Packaging is an integral part of a product, protecting it from biological, chemical, and physical damage during its journey from the factory to the consumer. Common packaging methods include bottling, canning, boxing, and bagging. Packaging bags are widely used due to their low cost, small size, light weight, and portability. However, traditional packaging bag raw materials often develop wrinkles during cutting and transportation, affecting the slitting process. Furthermore, the distance between the slitting blades cannot be adjusted according to the size of the raw material when cutting beverage packaging bags. Therefore, a packaging bag processing system and method need to be designed to solve these problems. Summary of the Invention

[0003] This invention provides a packaging bag processing system and method, the purpose of which is to stretch and iron the packaging bag to prevent wrinkles from forming during the processing.

[0004] The above objectives are achieved through the following technical solutions:

[0005] A method for processing packaging bags, the method comprising the following steps:

[0006] Step 1: Place the rolled-up packaging bag into the packaging bag processing system;

[0007] Step 2: Unfold and flatten the packaging bag;

[0008] Step 3: Dry and heat-press the packaging bags;

[0009] Step 4: Cut the packaging bag;

[0010] Step 5: Press the packaging bag firmly and store it.

[0011] The packaging bag processing system includes a support plate, on which a mounting frame I is fixedly attached; the rolled packaging bag from step one is placed on the mounting frame I.

[0012] The packaging bag processing system also includes a base plate, on which two rotating shafts I are rotatably connected. Each rotating shaft I has a bevel gear I fixed above it and a roller fixed below it. Two mounting plates are fixed to the base plate, and a rotating shaft II is rotatably connected between the two mounting plates. Bevel gears II are fixed to both sides of the rotating shaft II, and each bevel gear II meshes with a corresponding bevel gear I.

[0013] A torsion spring is fixed between the rotating shaft II and the mounting plate.

[0014] An outer shell is fixedly connected to the base plate, and two push rods are fixedly connected to the outer shell. A frame plate is slidably connected to the two push rods. Two springs are fixedly connected between the outer shell and the frame plate, and the two springs are respectively sleeved on the outer side of the corresponding push rod.

[0015] Two supports are fixedly attached to the bottom of the frame plate. Two rollers are rotatably connected to the front and rear sides of the two supports, and a conveyor belt is installed on the two rollers. Mounting brackets II are fixedly attached to both supports and both mounting brackets II are fixedly attached to the support plate. Motor I is fixedly attached to the two supports on the left side. The output shaft of motor I passes through the support and is fixedly attached to the roller on the rear side.

[0016] An air cylinder is fixedly attached to the support plate. A mounting frame is fixedly attached to the right side of the air cylinder. Ventilation plates are fixedly attached to the left and right sides of the mounting frame, respectively. Motor II is fixedly attached to the ventilation plate on the left side. The output shaft of motor II passes through the ventilation plate, and a fan blade assembly is fixedly attached to the output shaft of motor II.

[0017] Air pipe I and air pipe II are fixedly connected to the left side of the air cylinder. Compression pipes are fixedly connected to air pipe I and air pipe II respectively. Air outlet I and air outlet II are fixedly connected to the two compression pipes respectively. Air outlet I is fixedly connected to the frame plate. A mounting bracket III is fixedly connected below air outlet II. The mounting bracket III is fixedly connected to the support plate.

[0018] The air outlet duct I is equipped with multiple heating rods, and an ironing board is fixed between the two mounting brackets II, with the ironing board located below the air outlet duct I.

[0019] A mounting bracket IV is fixedly connected to the support plate. Two pressure cylinders are rotatably connected to the mounting bracket IV. Gears are fixedly connected to the right side of each pressure cylinder, and the two gears are meshed together. A transmission belt is installed between the lower pressure cylinder and the rear roller.

[0020] The beneficial effects of the packaging bag processing system and method of the present invention are as follows:

[0021] Compared to traditional packaging bag processing systems and methods, this invention features two rollers that move together via two pairs of bevel gears. A torsion spring generates elasticity, causing the rollers on both sides to swing outwards. When the packaging bag passes over the rollers, friction causes the rollers to swing inwards and rotate. This rotation pulls the packaging bag to both sides, flattening it out. The rollers' swinging motion also pulls and unfolds the packaging bag, preventing wrinkles from forming during processing.

Detailed Implementation

[0036] A method for processing packaging bags, the method comprising the following steps:

[0037] Step 1: Place the rolled-up packaging bag into the packaging bag processing system;

[0038] Step 2: Unfold and flatten the packaging bag;

[0039] Step 3: Dry and heat-press the packaging bags;

[0040] Step 4: Cut the packaging bag;

[0041] Step 5: Press the packaging bag firmly and store it.

[0042] The packaging bag processing system includes a support plate 501, on which a mounting frame I 502 is fixedly connected; the rolled packaging bag from step one is placed on the mounting frame I 502.

[0043] See Figures 1-6 A schematic diagram of an embodiment of the meshing connection between bevel gear I 103 and bevel gear II 107 according to the present invention is shown. Further,

[0044] The packaging bag processing system also includes a base plate 101, on which two rotating shafts I 102 are rotatably connected. A bevel gear I 103 is fixed above each rotating shaft I 102, and a roller 104 is fixed below each rotating shaft I 102. Two mounting plates 105 are fixed on the base plate 101, and a rotating shaft II 106 is rotatably connected between the two mounting plates 105. Bevel gears II 107 are fixed on both sides of the rotating shaft II 106, and each bevel gear II 107 meshes with the corresponding bevel gear I 103. At the same time, a torsion spring 108 is fixed between the rotating shaft II 106 and the mounting plate 105.

[0045] The base plate 101 provides a mounting position for the rotating shaft I 102 and also supports the mounting plate 105, bevel gear I 103, and bevel gear II 107. When one roller 104 rotates around the rotating shaft I 102, it drives the corresponding bevel gear I 103 to rotate, which in turn drives the corresponding bevel gear II 107 to rotate. A rotating shaft II 106 is fixed between the two bevel gears II 107, causing both bevel gears II 107 to rotate simultaneously. Therefore, the rotation of one roller 104 drives the rotation of the other roller 104, thus enabling the two rollers 104 to rotate. It can always maintain a symmetrical position angle; a torsion spring 108 is fixed between the rotating shaft II 106 and the mounting plate 105, so that the rotating shaft II 106 has a tendency to rotate forward, which can drive and make the rollers 104 on both sides have a tendency to swing outward; when the packaging bag passes the rollers 104 on both sides, under the action of friction, the rollers 104 rotate inward and rotate themselves. Their rotation can pull the packaging bag to both sides and make it spread out flat. At the same time, when the rollers 104 on both sides rotate to return to the initial position, they can also pull the packaging bag and make it spread out.

[0046] See Figures 1-6 A schematic diagram of an embodiment of the engagement connection between push rod 110 and spring 111 according to the present invention is shown. Further,

[0047] A housing 109 is fixedly connected to the base plate 101. Two push rods 110 are fixedly connected to the housing 109. A frame plate 112 is slidably connected to the two push rods 110. Two springs 111 are fixedly connected between the housing 109 and the frame plate 112. The two springs 111 are respectively sleeved on the outside of the corresponding push rods 110.

[0048] The outer casing 109 can protect the inner mounting plate 105, bevel gear I 103 and bevel gear II 107 and other parts; the spring 111 can make the outer casing 109 tend to move away from the frame plate 112, thereby pushing the roller 104 downward, thus ensuring that the roller 104 can press down on the packaging bag; the two push rods 110 can limit the movement trajectory of the outer casing 109 and prevent the outer casing 109 and the two rollers 104 from deviating.

[0049] See Figures 1-6 A schematic diagram of an embodiment of the present invention showing the meshing connection of two rollers 202 and a conveyor belt 205 is shown. Further,

[0050] Two brackets 201 are fixedly attached to the bottom of the frame plate 112. Two rollers 202 are rotatably connected to the front and rear sides of the two brackets 201 respectively. A conveyor belt 205 is installed on the two rollers 202. Mounting brackets II 503 are fixedly attached to both brackets 201. Both mounting brackets II 503 are fixedly attached to the support plate 501. Motor I 203 is fixedly attached to the two brackets 201 on the left side. The output shaft of motor I 203 passes through the bracket 201 and is fixedly attached to the rear roller 202.

[0051] The two supports 201 can fix the two rollers 202, so that the two rollers 202 can rotate stably; at the same time, the two rollers 202 can rotate together through the conveyor belt 205; the motor I 203 can drive the rollers 202 to rotate, which in turn causes the conveyor belt 205 to roll forward, thereby driving the packaging bag that is tightly attached to the conveyor belt 205 to roll forward.

[0052] See Figures 7-11 A schematic diagram of an embodiment of the invention in which air pressure is generated by air cylinder 301 is shown. Further,

[0053] An air cylinder 301 is fixedly connected to the support plate 501. An installation frame 302 is fixedly connected to the right side of the air cylinder 301. Ventilation plates 303 are fixedly connected to the left and right sides of the installation frame 302 respectively. A motor II 304 is fixedly connected to the ventilation plate 303 on the left side. The output shaft of the motor II 304 passes through the ventilation plate 303. A fan blade assembly 305 is fixedly connected to the output shaft of the motor II 304.

[0054] The motor II 304 can drive the fan blade assembly 305 to rotate, thereby generating airflow inward and increasing the internal air pressure. The number of fan blade assemblies 305 can be increased to increase the airflow size, thereby increasing the air pressure inside the air cylinder 301. The ventilation plate 303 allows airflow to pass through and provides an installation position for the fan blade assembly 305.

[0055] See Figures 7-11 A schematic diagram of an embodiment of the present invention, showing airflow generated by air outlet I 309 and air outlet II 310, is shown. Further,

[0056] Air pipe I 306 and air pipe II 307 are fixedly connected to the left side of air cylinder 301. Compression pipes 308 are fixedly connected to air pipe I 306 and air pipe II 307 respectively. Air outlet I 309 and air outlet II 310 are fixedly connected to the two compression pipes 308 respectively. Air outlet I 309 is fixedly connected to frame plate 112. Mounting bracket III 504 is fixedly connected below air outlet II 310. Mounting bracket III 504 is fixedly connected to support plate 501.

[0057] The airflow inside the air cylinder 301 enters the air outlet ducts 309 and 310 through the air pipes 306 and 307 and the compression pipe 308, respectively. The narrow openings of the air outlet ducts 309 and 310 allow for further gas compression, thereby increasing the gas flow rate. The compression pipe 308 is equipped with multiple tapered air ducts to increase air pressure. The airflow generated by the air outlets 309 and 310 located on the upper and lower sides respectively causes the packaging bag in the middle to be blown backward while maintaining a horizontal position. At this time, the packaging bag is cut, and the cut packaging bag moves to the lower part of the pressure cylinder 401 under the action of the airflow. The high-speed airflow can wash the packaging bag to prevent debris from falling on the packaging bag and reduce the odor on the packaging bag.

[0058] See Figures 7-11 This diagram illustrates an embodiment of the invention in which the airflow inside the air outlet duct I 309 is heated by a heating rod 311. Further,

[0059] Multiple heating rods 311 are installed inside the air outlet I 309, and an ironing plate 204 is fixed between the two mounting brackets II 503. The ironing plate 204 is located below the air outlet I 309.

[0060] The heating rod 311 can heat the airflow entering the air outlet duct I 309, thereby heating the bottom of the air outlet duct I 309. The airflow heating can prevent the bottom of the air outlet duct I 309 from overheating and thus prevent overheating from damaging the packaging bag. At the same time, the high-temperature dry airflow blown out by the air outlet duct I 309 can dry the packaging bag.

[0061] See Figures 1-13This shows a schematic diagram of an embodiment of the invention in which a packaging bag is squeezed by two pressure cylinders 401. Further,

[0062] A mounting bracket Ⅳ505 is fixedly connected to the support plate 501. Two pressure cylinders 401 are rotatably connected to the mounting bracket Ⅳ505. Gears 402 are fixedly connected to the right side of each of the two pressure cylinders 401, and the two gears 402 are meshed together. A transmission belt 403 is installed between the lower pressure cylinder 401 and the rear roller 202.

[0063] Two gears 402 can drive two pressure cylinders 401 to rotate respectively, and the two gears 402 mesh to achieve rotation in opposite directions, thereby squeezing the packaging bag; the transmission belt 403 can make the roller 202 and the pressure cylinder 401 rotate simultaneously; the mounting bracket Ⅳ505 can provide a mounting position for the two pressure cylinders 401 and play a stabilizing role in the rotation of the two pressure cylinders 401.
