Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: A packaging bag flattening device for printing packaging bags, comprising: The main conveyor belt 1 has a fixed frame 2 fixedly connected to its outer side, and two anti-blocking components 8 are provided on the side wall of the main conveyor belt 1 to prevent material blockage. Both anti-blocking components 8 include a protective shell 81, an anti-blocking motor 82, a rotating block 83, a fixed shell 86, and an extension rod 88; The main conveyor belt 1 has two symmetrically distributed protective shells 81 fixedly connected to its upper end. An anti-blocking motor 82 is fixedly connected to the upper end of the two protective shells 81. A rotating block 83 is fixedly connected to the output shaft of the anti-blocking motor 82. The rotating block 83 is rotatably connected to the protective shell 81. A fixing ring 84 is rotatably connected to the lower end of the rotating block 83. A fixing plate 85 is fixedly connected to the lower end of the fixing ring 84. The fixing plate 85 is fixedly connected to the main conveyor belt 1. Multiple fixing shells 86 are fixedly connected to the side wall of the rotating block 83. Sliding discs 87 are slidably connected inside the multiple fixing shells 86. The sliding discs 87 are fixedly connected to the extension rods 88. The extension rods 88 are slidably connected inside the fixing shells 86. Springs 89 are provided between the rotating block 83 and the multiple sliding discs 87.

[0018] For example, the main conveyor belt 1 is made of high-strength, wear-resistant rubber material, and its surface is specially treated to have a certain degree of friction to ensure that the packaging bags will not easily slip during transportation. The fixing frame 2 provides a stable support structure for the entire device. It is made of high-quality steel and has sufficient strength and rigidity to withstand various forces generated during the operation of the device. The two anti-blocking components 8 work together to effectively prevent material blockage and ensure smooth transportation of the packaging bags. The protective shell 81 is made of metal and has good protective performance, effectively protecting internal components such as the anti-blocking motor 82 from external dust, debris, and impacts. The anti-blocking motor 82 is a high-performance servo motor with advantages such as stable speed, high torque, and fast response. It can precisely control the rotation speed and angle according to actual needs. The rotating block 83 can rotate smoothly and steadily under the drive of the anti-blocking motor 82. The fixing ring 84 and the fixing plate 85 support the rotating block 83. The sliding disk 87 is made of high-strength plastic material, which is lightweight and wear-resistant. The extension rod 88 is used to directly contact the packaging bag to clear the blockage. The spring 89 is made of high-quality spring steel, which has good elasticity and durability. It can provide buffering and restoring force when the extension rod 88 is resisted, ensuring the normal operation of the anti-blocking component 8.

[0019] Two symmetrically distributed sliders 810 are fixedly connected to the side wall of the sliding disk 87, and the sliders 810 are slidably connected to the multiple fixed shells 86 respectively.

[0020] For example, the two sliders 810 are slidably connected to the sliding grooves provided inside the multiple fixed shells 86. The precision of the sliding grooves is strictly processed to ensure that the sliders 810 have low friction and smooth movement when sliding. Through this slider and sliding groove cooperation design, the movement trajectory of the sliding disk 87 is effectively limited, preventing it from deviating or getting stuck during the sliding process, thereby improving the working reliability and stability of the anti-blocking component 8.

[0021] An electric actuator 3 is fixedly connected inside the fixed frame 2. A lifting frame 4 is fixedly connected to the output end of the electric actuator 3. Two guide rods 5 are fixedly connected to the upper end of the lifting frame 4. The two guide rods 5 are slidably connected to the fixed frame 2 respectively. A limit plate 6 is fixedly connected to the upper end of each of the two guide rods 5.

[0022] For example, the electric actuator 3 is a high-performance electric linear actuator, which has the advantages of large thrust, precise stroke, and smooth operation. It can accurately control the extension and retraction length of the output end according to the instructions of the control system. The lifting frame 4 is made of aluminum alloy, which is lightweight and high-strength, and can reduce the overall weight of the device while ensuring structural strength. The guide rod 5 is a high-precision optical shaft with a chrome-plated surface, which has good wear resistance and smoothness. The fixed frame 2 has two symmetrically distributed through holes for the lifting of the guide rod 5. The upper ends of the two guide rods 5 are fixedly connected to the limit plate 6 by welding. The diameter of the limit plate 6 is larger than the inner diameter of the through hole. When the guide rod 5 descends to a certain position, the limit plate 6 will contact the upper end of the through hole, thereby playing a limiting role and ensuring the safe operation of the device.

[0023] The lifting frame 4 is equipped with a downward conveyor belt 7 inside, and a motor for driving the downward conveyor belt 7 to rotate is installed on the side wall of the lifting frame 4.

[0024] For example, the pressing conveyor belt 7 uses a rubber belt of the same material as the main conveyor belt 1 to ensure consistency in friction and elasticity, thereby improving the flattening effect of the packaging bag. The side wall of the lifting frame 4 is equipped with a motor for driving the pressing conveyor belt 7 to rotate. The motor is a speed-regulating motor, which can flexibly adjust the rotation speed of the pressing conveyor belt 7 according to factors such as the material and thickness of the packaging bag to meet the flattening requirements of different packaging bags. The motor transmits power to the drive roller of the pressing conveyor belt 7 through belt drive or gear drive, and the drive roller drives the pressing conveyor belt 7 to rotate smoothly.

[0025] Working principle: The packaging bag is placed on the main conveyor belt 1 and started. The main conveyor belt 1 drives the packaging bag forward. At the same time, the anti-blocking motor 82 starts, driving the rotating block 83 to rotate smoothly and steadily inside the protective shell 81. The multiple fixed shells 86 on the side wall of the rotating block 83 rotate accordingly. When encountering materials that may cause blockage, the extension rod 88 pushes the sliding disc 87 to slide inside the fixed shell 86 under the action of material resistance, compressing the spring 89. The spring 89 generates a buffering force to prevent the extension rod 88 from being damaged due to excessive force. At the same time, when the extension rod 88 rotates, it drives the packaging bag to move downward in the direction of pressing the conveyor belt 7. When the material is cleared, the restoring force of the spring 89 makes the extension rod 88 return to its original position and continue to work normally. The two anti-blocking components 8 work together to ensure the smooth transportation of the packaging bag on the main conveyor belt 1. Depending on the thickness of the packaging bag, the electric push rod 3 pushes the lifting frame 4 to rise or fall. When the lifting frame 4 falls to the appropriate position, the drive motor of the pressure conveyor belt 7 starts, driving the pressure conveyor belt 7 to rotate smoothly. The pressure conveyor belt 7 cooperates with the main conveyor belt 1 to flatten the packaging bag during transportation. If the flattening effect is not good, the rotation speed or height of the pressure conveyor belt 7 is adjusted in time.

[0026] In this application, the main conveyor belt 1, electric push rod 3, pressing conveyor belt 7, and anti-blocking motor 82 are controlled automatically by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
