Description

Technical Field

[0001] The invention relates to the technical field of packaging bag packaging and conveying, in particular to a conveying mechanism and processing technology for producing medical packaging bags. Background Art

[0002] The conveying equipment for medical packaging bag production is specially designed for medical packaging bags after production. It is used to efficiently and orderly convey the finished medical packaging bags from the end of the production line to the collection area. These devices usually take the form of belts, rollers or chains. Through continuous and smooth conveying actions, they ensure that the medical packaging bags are not damaged during the transportation process and effectively improve production efficiency to meet the needs of rapid collection and sorting after production.

[0003] In the prior art, the functional limitations of the conveying device for the production of medical packaging bags are becoming increasingly prominent, especially when processing paper packaging bags. Due to the material characteristics of paper packaging bags, they are prone to form a fluffy state when stacked, resulting in a significant increase in the overall volume. This volume expansion not only occupies more conveying space, requiring the conveying device to be designed to be longer and wider to accommodate more packaging bags, but also directly increases the energy consumption and wear during the conveying process. In addition, the fluffy paper packaging bags are prone to offset or collapse during the conveying process, requiring more frequent adjustments and maintenance, further increasing the conveying cost. These shortcomings not only affect the production efficiency, but also increase the operating costs of the enterprise. To this end, we propose a conveying mechanism and processing technology for the production of medical packaging bags. Summary of the invention

[0043] Furthermore, the feeding mechanism 1 and the lifting and translation mechanism 2 work together to realize the automatic unloading and conveying of the sealed bag 15 and the paper packaging bag 16 inside it after the compression and packaging are completed, which greatly reduces manual intervention, improves the degree of automation of the production line, and thus speeds up the production speed. The sealing unit 4 on the supporting mechanism 3, in conjunction with the use of the pressing mechanism 9, can evenly and effectively compress the sealed bag 15 filled with paper packaging bags 16 to reduce the volume and facilitate subsequent storage and transportation.

The stable structure of the load-bearing plate 201 and the fixed plate 202 provides a strong supporting force for the entire jacking and translation mechanism 2, ensuring stability and safety under high-load working conditions. Through the extension and retraction of the three electric push rods 3010, the inclination angle of the placement platform 304 can be easily adjusted to meet the placement requirements of sealing bags 15 of different sizes, weights and sizes during unloading. At the same time, the design of the reinforcement bolts 302 makes the connection between the docking plate 301 and the slider 207 more firm and reliable. The lower heating plate 306 can provide the necessary heat for the sealing bag 15 during the compression process, promote the melting and bonding of the sealing material, and improve the sealing effect, while the lower sealing strip 305 further enhances the tightness and reliability of the seal. The lower heating plate 306 has a built-in heating wire. Through the use of the hinge and the electric push rod 3010, the smooth rotation and tilt adjustment of the placement platform 304 is realized, avoiding the potential safety hazards such as sudden falling or tilting during operation.

At the upper end of 403, both ends of the two protective shells 501 are fixedly connected with support plates 502, and two crank shafts 503 are rotatably sleeved inside the two support plates 502 on one side and the two support plates 502 on the other side through bearings, and multiple connecting rods 504 are arranged and rotatably sleeved on the outside of the two crank shafts 503, and two positioning plates 505 are fixedly connected to the side away from each other between the two support plates 502 on one side and the two support plates 502 on the other side, and multiple sealing cylinder sleeves 506 are arranged and fixedly sleeved inside the two positioning plates 505, and first piston heads 507 are slidably sleeved inside the multiple sealing cylinder sleeves 506, and connecting rods 508 are fixedly connected inside the multiple first piston heads 507, and the other ends of the multiple connecting rods 504 are rotatably sleeved on the multiple connecting rods 504. 08 outside, a first three-way pipe 509 is arranged on one side of the plurality of sealed cylinder sleeves 506, one end of the plurality of first three-way pipes 509 passes through the outside of the sealed cylinder sleeve 506 to the inside of the sealed cylinder sleeve 506, the other two ends of the plurality of first three-way pipes 509 are respectively fixedly connected with an intake check valve 5010 and an exhaust check valve 5011, the input ends of the plurality of intake check valves 5010 are respectively fixedly connected with an exhaust pipe 13, the input ends of the plurality of exhaust pipes 13 respectively pass through both sides of the sealing cover 401 to the inside of the sealing cover 401, the output ends of the plurality of exhaust check valves 5011 are respectively fixedly connected with a second three-way pipe 5012, the other two ends of the plurality of second three-way pipes 5012 are respectively fixedly connected with a first solenoid valve 5013 and a second solenoid valve 5014, and the plurality of first solenoid valves 5 013 output ends are fixedly connected with gas pipeline 14, driving mechanism 6 comprises driving motor 601, driving motor 601 is fixedly connected to the upper end of sealing cover 401, output end of driving motor 601 is fixedly connected with main driving sprocket 602, synchronization mechanism 7 comprises second support column 701, second transmission sprocket 703 and third transmission sprocket 704, second support column 701 is rotatably connected to the center of one side of sealing cover 401, second transmission sprocket 703 and third transmission sprocket 704 are respectively fixedly connected to two crankshafts 503 near one end of second support column 701, one side of second support column 701 is fixedly connected with first transmission sprocket 702, and the first transmission sprocket 702 is fixedly connected with the fourth transmission sprocket 705 at the side away from second support column 701,The fourth transmission sprocket 705 is fixedly connected to the auxiliary transmission sprocket 706 at the side away from the first transmission sprocket 702. The first transmission sprocket 702 and the second transmission sprocket 703 are sleeved with a first chain 707 on the outside. The third transmission sprocket 704 and the fourth transmission sprocket 705 are sleeved with a second chain 708 on the outside. The auxiliary transmission sprocket 706 and the main drive sprocket 602 are sleeved with a drive chain 709 on the outside. A protective cover 8 is fixedly connected to one side of the sealing cover 401.

[0049] Furthermore, the sealing cover 401 is tightly fitted with the lower sealing strip 305 on the placement platform 304 through the upper sealing strip 402, which effectively prevents external gas from entering the sealing cover 401 during the compression packaging process. At the same time, the fixed connection between the docking ear piece 404 and the jacking hydraulic rod 204 enables the sealing cover 401 to be automatically raised and lowered, realizing the automation and seamless docking of the sealing process. The downward hydraulic rod 10 cooperates with the upper heating plate 12 and the lower heating plate 306 to work synchronously during the compression process, providing uniform and efficient heating for the sealing portion of the sealing bag 15, promoting the melting and bonding of the sealing material, and ensuring the firmness and reliability of the seal. The temperature and time of the upper heating plate 12 The time can also be adjusted as needed to meet the heating requirements of sealing bags 15 of different materials and specifications. When the sealing cover 401 is lowered to fit with the supporting mechanism 3, the exhaust mechanism 5 starts to work, and the driving motor 601 drives the two crank shafts 503 to rotate through the synchronous mechanism 7, and then drives the first piston head 507 to reciprocate in the sealing cylinder sleeve 506 through the connecting rod 504. When the first piston head 507 moves into the sealing cylinder sleeve 506, the air in the sealing cover 401 is extracted through the air inlet check valve 5010 and the exhaust pipe 13. When the first piston head 507 moves outward, the air is exhausted through the air outlet check valve 5011 and the second three-way pipe 5012. The gas is transported to the pressing mechanism 9 through the first solenoid valve 5013 and the gas pipeline 14, thereby driving the pressing mechanism 9 to operate, thereby further realizing the gas recycling. The operation of the air extraction mechanism 5 effectively reduces the air pressure in the sealing cover 401, providing more favorable environmental conditions for the compression and sealing of the sealing bag 15. At the same time, by controlling the switching states of the first solenoid valve 5013 and the second solenoid valve 5014, the accurate control of the air extraction process can be achieved, ensuring the efficiency and effect of the air extraction. The synchronization mechanism 7 realizes the synchronous rotation of the two crank shafts 503 through the transmission of the first chain 707, the second chain 708 and the driving chain 709. This design not only improves the transmission efficiency, but also ensures the synchronization and consistency of the operation of both sides of the vacuum mechanism 5. The drive motor 601 serves as the power source of the entire vacuum mechanism 5. It transmits power to the synchronization mechanism 7 through the main drive sprocket 602 and the drive chain 709, thereby driving the crank shaft 503 to rotate. This power transmission method is stable and reliable, and can ensure the stability and reliability of the vacuum mechanism 5 under long-term operation. The protective cover 8 provides additional protection for the drive mechanism 6 and the synchronization mechanism 7 to prevent debris from entering the mechanism and affecting its normal operation. At the same time, the protective cover 8 also has a certain sound insulation effect, which reduces the noise pollution generated by the equipment during operation.

[0050] In the preferred technical solution of this embodiment, please refer to Fig.17, multiple pressing mechanisms 9 all include sealing tubes 901, multiple sealing tubes 901 are slidably sleeved with pressing rods 902 at the lower parts, multiple pressing rods 902 are fixedly connected with second piston heads 903 at the upper ends, multiple second piston heads 903 are respectively slidably sleeved in the multiple sealing tubes 901, multiple sealing tubes 901 are slidably sleeved with lifting and returning springs 904 at the lower parts, multiple lifting and returning springs 904 are respectively sleeved on the outsides of multiple pressing rods 902, multiple lower ends of lifting and returning springs 904 are respectively in contact with the inner bottom walls of multiple sealing tubes 901, multiple upper ends of lifting and returning springs 904 are respectively in contact with the lower ends of multiple second piston heads 903, multiple sealing tubes 901 are opened at the upper parts of one side, multiple gas pipelines 14 output ends are respectively fixedly sleeved in the multiple gas inlet holes 905, and multiple pressing rods 902 are fixedly connected with pressing plates 11 at the lower ends.

[0051] Furthermore, after the sealing cover 401 descends and fits with the supporting mechanism 3, the exhaust mechanism 5 starts to work. As the first piston head 507 reciprocates in the sealing cylinder sleeve 506, the air in the sealing cover 401 is extracted and transported to the sealing tube 901 of the pressing mechanism 9 through the gas pipeline 14. When the gas enters the sealing tube 901, it pushes the second piston head 903 and the pressing rod 902 to move downward, and the pressing plate 11 contacts and compresses the sealing bag 15. At this time, the lifting and returning spring 904 is compressed and stores energy. As the exhaust process proceeds, the air pressure in the sealing cover 401 gradually decreases. , providing more favorable environmental conditions for the compression and sealing of the sealing bag 15. At the same time, by controlling the switching state of the first solenoid valve 5013, the gas flow entering the pressing mechanism 9 can be accurately adjusted, thereby controlling the pressing speed and strength of the pressing rod 902. When the air extraction process is completed or the pressing needs to be stopped, the first solenoid valve 5013 is closed, and the gas in the pressing mechanism 9 is gradually discharged. At this time, the lifting and returning spring 904 releases the stored energy, pushing the pressing rod 902 and the second piston head 903 to quickly return to the initial position, preparing for the next pressing operation, by pumping air. The gas discharged from the mechanism 5 is introduced into the sealed tube 901 of the pressing mechanism 9 after being controlled by the first solenoid valve 5013, thereby realizing the recycling of the gas. This not only reduces the dependence on fresh air from the outside, but also saves energy and reduces the cost of equipment operation. When the pressing mechanism 9 receives the gas from the exhaust mechanism 5, the gas enters the sealed tube 901 through the air inlet 905, pushing the second piston head 903 and the pressing rod 902 to move downward. In this process, the lifting and returning spring 904 is compressed, storing elastic potential energy. When the gas is discharged or the pressure is reduced, the lifting and returning spring 904 releases the energy. The amount is pushed to quickly reset the pressing rod 902, thereby enhancing the power and efficiency of the pressing. By controlling the switching state of the first solenoid valve 5013, the gas flow and pressure entering the pressing mechanism 9 can be accurately adjusted, thereby achieving precise control of the pressing speed and strength of the pressing rod 902. This control method ensures the stability and consistency of the sealing bag 15 during the compression process. The pressing mechanism 9 and the exhaust mechanism 5 are seamlessly connected through the gas pipeline 14, making the entire compression and exhaust process highly automated and integrated, which not only simplifies the operating process, but also improves the overall performance and reliability of the equipment.
