[0004] However, based on the working principle proposed in the above patent, the applicant believes that the material in the above device is pushed by a screw conveyor. Since the discharge port is at a fixed height, the material has a certain impact force when entering the packaging bag, which in turn causes the pressure on the packaging bag fixing mechanism to increase, thereby affecting the product packaging.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] like Figures 1 to 4 As shown, the utility model provides a product bagging machine, including a base 1 and a storage box 2, a collecting hopper 3 is fixedly installed at the bottom of the storage box 2, a discharge pipe 4 is fixedly installed at the middle part of the bottom of the collecting hopper 3, a telescopic beam tube 5 is threadedly connected to the bottom of the discharge pipe 4, a connecting plate 6 is fixedly installed at the bottom of the surface of the telescopic beam tube 5, a cylinder 7 is fixedly installed on one side of the bottom of the collecting hopper 3, a telescopic rod 8 is arranged at the bottom of the cylinder 7, the telescopic rod 8 is threadedly connected to the connecting plate 6, and an electric valve 9 is fixedly installed on one side of the discharge pipe 4.

[0023] Among them, through the structural design of the discharge pipe 4, the telescopic beam pipe 5, the connecting plate 6, the cylinder 7, and the telescopic rod 8, and through the mutual cooperation between the structures, the function of material limiting is realized, thereby reducing the impact force of the material on the packaging bag, thereby reducing the risk of the packaging bag breaking or damaging, and at the same time reducing the pressure on the packaging bag fixing structure, thereby ensuring the service life of the device. The function of automatically controlling the material discharge flow is realized through the electric valve 9, thereby the flow and discharge speed can be accurately adjusted as needed, ensuring the stability and consistency of the discharge process, and thus ensuring the uniformity of product packaging.

[0024] A driving motor 10 is fixedly mounted on one side of the base 1 , and a conveyor belt 11 is movably mounted inside the base 1 . The driving motor 10 and the conveyor belt 11 are connected in gear meshing manner.

[0025] Among them, the function of conveying packaging bags is realized through the structural design of the driving motor 10 and the conveyor belt 11, and through the mutual cooperation between the structures, so that the packaging bags can be automatically conveyed to the filling area, and the filled packaging paper can also be transferred to the filling area, further achieving the purpose of automatic operation of the device.

[0026] A plurality of mounting plates 12 are fixedly mounted on both sides of the surface of the conveyor belt 11 , and a through hole 13 is formed at the top of one side of the mounting plate 12 .

[0027] Among them, the assembly plate 12 is used to facilitate the support of the packaging bag fixing structure, and it can also be connected to the conveyor belt 11, thereby ensuring the stability and accuracy of automatic filling. The through hole 13 is used to facilitate the provision of moving space for the support rod 14, thereby ensuring that the fixing structure is suitable for packaging bags of different sizes, thereby increasing the flexibility of the device.

[0028] A support rod 14 is movably installed inside the through hole 13 , an arc-shaped plate 15 is fixedly installed at one end of the support rod 14 , and an arc-shaped limiting strip 16 is fixedly installed at the bottom of the arc-shaped plate 15 .

[0029] Among them, the function of opening the top of the packaging bag is realized by the arc plate 15, thereby ensuring that the telescopic bundle tube 5 can stably enter the packaging bag to complete the filling. The arc limit strip 16 is used to limit the bag mouth of the packaging bag to prevent the packaging bag from detaching from the arc plate 15 due to interference from material falling during filling.

[0030] A spring 17 is sleeved on the surface of the support rod 14 , and a limit plate 18 is fixedly mounted on the other end of the support rod 14 .

[0031] Among them, the function of fixing the bag opening is achieved by the spring 17 and the limit plate 18, thereby ensuring that the packaging bag remains stable during transportation and filling, avoiding loosening or deformation of the bag opening, and at the same time, the bag opening of the packaging bag can be quickly fixed at the set position, saving operation time and ensuring the efficient operation of the automated production line.

[0032] A control panel 19 is fixedly mounted on one side of the base 1 away from the input end, and a plurality of limit frames 20 are fixedly mounted on both sides of the base 1 .

[0033] The control panel 19 allows the operator to flexibly control the working state of the drive motor 10 to adapt to different working requirements or production processes.

[0034] Observation windows 21 are provided on both sides of the material storage box 2 , and L-plates 22 are threadedly connected to the four corners of the bottom of the collecting hopper 3 , and legs 23 are fixedly installed at the bottom of the L-plates 22 .

[0035] The observation window 21 allows the staff to check the material reserves in real time so as to replenish them in time, thereby ensuring the accuracy of filling.

[0036] The working principle and use process of the utility model are as follows: when using the device, the material is carried by the storage box 2, and the spring 17 is compressed by the limit plate 18. The spring 17 is deformed by the pressure. At this time, the distance between the arc plates 15 on both sides becomes smaller, and the inner wall of the bag mouth of the packaging bag is in contact with the outer wall of the arc plate 15. The limit plate 18 is released, and the spring 17 releases the tension. The support rod 14 is driven to move through the limit plate 18, and the arc plate 15 is driven to move through the support rod 14. The arc plate 15 ensures that the bag mouth of the packaging bag is in an open state, and the arc limit strip 16 provides a downward resistance to the bag mouth of the packaging bag. The drive motor 10 is programmed through the PLC controller, and the single rotation stroke of the drive motor 10 is set. The drive motor 10 is started through the control panel 19, and the drive motor 10 is turned on. The packaging bag is conveyed to the bottom of the storage box 2 through the conveyor belt 11, and the cylinder 7 drives the telescopic beam tube 5 to move into the packaging bag through the telescopic rod 8. The bottom wall of the inner cavity of the packaging bag is pressed by the telescopic beam tube 5 to ensure that the bottom of the packaging bag is in contact with the conveyor belt 11. The discharge pipe 4 is opened by the electric valve 9, and the material falls with its own weight, is limited by the collecting hopper 3, enters the telescopic beam tube 5 through the discharge pipe 4, and is limited by the telescopic beam tube 5 to avoid the splashing of the material and causing shaking of the packaging bag. As the material is filled, the cylinder 7 gradually raises the height of the telescopic beam tube 5 through the telescopic rod 8. When the electric valve 9 is started for a certain period of time, the filling is completed, and the discharge pipe 4 is closed by the electric valve 9. Finally, the filled packaging bag is conveyed to the side away from the input end through the conveyor belt 11.
