DETAILED DESCRIPTION

[0026] The following will be combined with the attached embodiment of the present utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] A multi-mode packaging bag opening machine comprises a bottom shell 1, an eccentric wheel 2 is rotatably installed inside the bottom shell 1, a stepper motor 3 is fixedly installed on the outer side of the bottom shell 1, the output shaft of the stepper motor 3 passes through the inside of the bottom shell 1 and is fixedly installed with the eccentric wheel 2, a movable cavity 4 connected with the inner cavity of the bottom shell 1 is opened on the top of the bottom shell 1, a movable support plate 5 is slidably installed inside the movable cavity 4, an adjustment seat 7 is movably installed inside the movable support plate 5, a top block 6 is detachably installed on the top of the adjustment seat 7, a top plate 10 is inserted into the inside of the top block 6, and the top plate 10 is detachably installed on the adjustment seat 7, and a opening assembly is arranged on the top of the bottom shell 1.

[0028] The specific usage process is as follows: first, the entire mouth-opening machine is installed on a matching device, such as a filling device or other required equipment, and the device is also equipped with a corresponding structure for removing the packaging bag. When working, the packaging bag is sent to the top of the mouth-opening machine, and then the tip of the support arm composed of multiple support plates 23 will be inserted into the packaging bag, and then the stepper motor 3 is started, and the stepper motor 3 drives the eccentric wheel 2 to rotate. Since the eccentric wheel 2 is an eccentric wheel structure, the eccentric wheel 2 will push the movable support plate 5 to move up, and then the movable support plate 5 will slide in the movable cavity 4. At the same time, the top block 6 installed on the adjustment seat 7 will also move upward with the movable support plate 5 in the movable cavity 4, and then the top block 6 will enter the base 19 and continue to enter the multiple support plates 23. Since the support arm composed of the multiple support plates 23 is a cone with the tip facing upward, it is small at the top and large at the bottom. Then, under the action of the top block 6, the multiple support plates 23 will be opened outward, and the support plates 23 will move in the movable cavity. When the support plate 23 is moved, the corresponding slider 21 will be driven to slide in the corresponding slide rail 20, which plays a role in guiding the moving direction of the support plate 23 and also plays a role in limiting the movement of the support plate 23, ensuring the stability of the support plate 23 when it moves. At the same time, the slider 21 will also compress the spring 22 when it moves. In this way, after the support plate 23 has finished its opening work, under the action of the spring 22, the slider 21 can be pushed back to its original position, and then the support plate 23 can be pushed back to its original position, thereby realizing the reset work after the support plate 23 works, providing convenience for the user's work and use. In this way, under the action of multiple support plates 23, the packaging bag mouth can be opened, and this working mode can open the packaging into a round mouth. Among them, when the mobile support plate 5 moves, it will also drive the limiting slide bar 17 to slide in the inner cavity of the limiting slide groove 18, so as to further limit and guide the movement of the mobile support plate 5, improve the stability of the mobile support plate 5 and the top block 6 when moving, and provide convenience for the user's work and use. This is the first use mode;

[0029] Usage mode 2: Before work, remove the top block 6 from the adjustment seat 7, and directly pull up the top block 6. At the same time, the mounting block 2 12 will also be moved out of the mounting groove 2 11, so that only the top plate 10 is left on the adjustment seat 7. Similarly, the package is sent to the top of the opening machine, and then the tip of the support arm composed of multiple support plates 23 will be inserted into the packaging bag, and then the stepper motor 3 is started, and the stepper motor 3 drives the eccentric wheel 2 to rotate. Since the eccentric wheel 2 is an eccentric wheel structure, the eccentric wheel 2 will push the moving support plate 5 to move up, and then the moving support plate 5 will slide in the moving cavity 4, and the adjusting seat 7 will also move with it. Then the top plate 10 installed on the adjustment seat 7 will also move accordingly, and then the top plate 10 extends from the surface of the moving cavity 4 and enters into the base 19, thereby opening the corresponding support plates 23 distributed on both sides of the top plate 10. Like the use mode 1, since the support arm composed of multiple support plates 23 is a cone with the tip facing upward, the upper part is small and the lower part is large, and then under the action of the top plate 10, the corresponding two support plates 23 will be opened outward, and the packaging bag will be opened into a long opening. When it is necessary to adjust the direction of the opened opening, the user can adjust it by rotating the direction of the top plate 10. Specifically, when the top plate 10 needs to be adjusted with which two support plates 23 When working in coordination, the user just rotates the top plate 10 to the position of the corresponding two support plates 23, so that the two support plates 23 can work separately, which provides convenience for the user's work and provides the user with more work options. The specific adjustment process is as follows: the user rotates the top plate 10, and the mounting block 9 is inserted into the mounting groove 8 during this process, so the top plate 10 can drive the adjustment seat 7 to rotate. When the adjustment seat 7 rotates, all the positioning pins 14 will also move accordingly. When the positioning pin 14 moves out of the positioning hole 16 at the current position, the positioning pin 14 will be squeezed into the corresponding sliding hole 16 under the action of the inner wall of the movable support plate 5. The positioning pin 14 is in the movable hole 13, and the positioning pin 14 will also compress the spring 15. When the positioning pin 14 moves to the position of the next positioning hole 16, under the action of the spring 15, the positioning pin 14 will pop out of the inner cavity of the sliding hole 13 and be inserted into the corresponding positioning hole 16. In this way, the direction of the top plate 10 can be adjusted, which provides convenience for the user's work. It should be noted that the adjustment work can also be set to be automatic. It only needs to set a motor at the corresponding position on the movable support plate 5, so that the motor is connected to the adjustment seat 7, and the adjustment seat 7 is driven by the motor to rotate, so as to realize the automatic rotation adjustment of the adjustment seat 7, which provides convenience for the user's work.

[0030] Therefore, a structural design with multiple working modes is adopted. Users can choose the appropriate working mode according to actual work needs. The packaging bag can be opened from multiple angles to form a long opening or a round opening.

When the top plate 10 needs to cooperate with which two support plates 23 to work, the user just rotates the top plate 10 to the position of the corresponding two support plates 23, so that the two separate support plates 23 can work, which provides convenience for the user's work and provides the user with more work options. The specific adjustment process is as follows: the user rotates the top plate 10, and during this process, the mounting block 9 is plugged into the mounting slot 8, so The top plate 10 can drive the adjustment seat 7 to rotate. When the adjustment seat 7 rotates, all the positioning pins 14 will also shift accordingly. When the positioning pin 14 moves out of the positioning hole 16 at the current position, the positioning pin 14 will be squeezed into the corresponding sliding hole 13 under the action of the inner wall of the movable support plate 5. At the same time, the positioning pin 14 will also compress the spring 15.
