[0028] A nursing bag containing medical supplies is placed on the workbench 1, and the upper opening of the nursing bag is placed between the heat sealing plate 5 and the heat sealer 9. The electric push rod 7 pushes the heat sealing table 8 to move toward the heat sealing plate 5, and the heat sealing table 8 drives the heat sealer 9 to move. The heat sealer 9 contacts and heats the nursing bag. The heat sealer 9 cooperates with the heat sealing plate 5 to melt and pressurize the upper end of the nursing bag, so that the upper opening of the nursing bag is tightly combined together to achieve the heat sealing edge operation of the nursing bag. The slide rail 6 has a guiding and limiting function for the heat sealing table 8, which improves the electric push rod 7 to push the heat sealer 9, to ensure the heat sealing quality of the nursing package; after heat sealing, there will be residues on the surface of the heat sealer 9, and the threaded rod 11 is driven by the driving mechanism to rotate, the threaded rod 11 pushes the slider 12 to move, and the slider 12 drives the scraper 13 to move, and the scraper 13 fits the outer surface of the heat sealer 9 to clean the residues sticking on its surface to avoid the residues affecting the subsequent heat sealing quality. When the heat sealer 9 cooperates with the heat sealing plate 5 to perform the heat sealing edge operation, the scraper 13 is located on one side of the heat sealer 9 and will not hinder the work of the heat sealer 9 (such as the attached Figure 5 shown).

[0029] It is further explained that the driving mechanism includes a slide rail 6 fixedly mounted on one side of the first mounting plate 3, a rack 21 fixedly mounted on one side of the slide rail 6, and a gear 20 meshing on the rack 21, a rotating rod 19 is fixedly connected to the lower end of the gear 20, the rotating rod 19 is rotatably mounted in the heat sealing table 8, a second bevel gear 18 is fixedly mounted on the lower end of the rotating rod 19, a first bevel gear 17 is meshed on one side of the second bevel gear 18, and an end face of the first bevel gear 17 is fixedly connected to one end of the threaded rod 11.

[0030] After the heat sealer 9 heat seals the care package, the electric push rod 7 pulls back the heat sealing table 8 and the heat sealer 9, and the heat sealer 9 drives the gear 20 to move. The gear 20 arranged on the heat sealing table 8 is meshed with the rack 21 fixed on one side of the slide rail 6 to rotate the gear 20, and the gear 20 drives the second bevel gear 18 to rotate through the rotating rod 19, and the second bevel gear 18 drives the first bevel gear 17 to rotate, and the first bevel gear 17 drives the threaded rod 11 to rotate to push the scraper 13 to move to clean the residue on the surface of the heat sealer 9. The driving mechanism realizes that the scraper 13 is automatically moved on the surface of the heat sealer 9 when the heat sealer 9 resets after completing the heat sealing, so as to automatically clean the residue on the surface of the heat sealer 9, avoid stopping to clean the residue on the heat sealer 9, thereby improving the efficiency of the device for heat sealing edge care packages.

[0032] The limiting hole 15 cooperates with the limiting strip 16 to guide and limit the slider 12, thereby preventing the slider 12 from flipping over when the threaded rod 11 rotates, improving the stability of the slider 12 when moving, and thus improving the stability of the slider 12 driving the scraper 13 to move and clean the residue on the surface of the heat sealer 9.

[0033] It is further explained that a collecting trough 14 is fixedly mounted on the lower end of the scraper 13 .

[0034] The collecting tank 14 can collect the residual debris on the heat sealer 9 scraped off by the scraper 13, so as to facilitate the cleaning of the treated residue and improve the practicality of the device.

[0036] The conveyor belt 2 is used to convey the nursing packages to be heat-sealed and after heat-sealing, reducing the labor intensity of the operators and improving the heat-sealing efficiency of the nursing packages; the support rod 22 supports the guide plate 23, and the guide plate 23 limits the nursing packages placed on the conveyor belt 2 to prevent the nursing packages placed on the conveyor belt 2 from shifting or tilting during the conveying process, thereby ensuring the conveying effect of the conveyor belt 2.

[0037] It is further explained that a curved guide plate 24 is fixedly connected to one side of the guide plate 23 , and the curved guide plate 24 is arranged on one side of the first mounting plate 3 .

[0038] The arc-shaped portion of the arc-shaped guide plate 24 guides the upper opening of the transported care package, and cooperates with the guide plate 23 on the opposite side of the arc-shaped guide plate 24 to make the upper opening of the transported care package close and fit together, so as to facilitate the subsequent conveyor belt 2 to be transported between the first mounting plate 3 and the second mounting plate 4. The heat sealer 9 cooperates with the heat sealing plate 5 to heat-seal the upper opening of the care package to improve the heat sealing quality of the care package.

[0039] Specific reference is made to the following operation: place the nursing package on the conveyor belt 2, the conveyor belt 2 drives the nursing package to move, the arc guide plate 24 cooperates with the guide plate 23 to make the upper end opening of the conveyed nursing package close and fit together, after the conveyor belt 2 conveys the nursing package to between the first mounting plate 3 and the second mounting plate 4, the conveyor belt 2 stops for a period of time, at which time the electric push rod 7 pushes the heat sealer 9 to move, the heat sealer 9 cooperates with the heat sealing plate 5 to melt and pressurize the upper end of the nursing package, so that the upper end opening of the nursing package is tightly combined together, and after the heat sealing edge is completed, the electric push rod 7 pulls back the heat sealer 9 The sealing table 8 and the heat sealer 9, the heat sealer 9 drives the gear 20 to move, the gear 20 arranged on the heat sealing table 8 is meshed with the rack 21 fixed on one side of the slide rail 6 to rotate the gear 20, the gear 20 drives the second bevel gear 18 to rotate through the rotating rod 19, the second bevel gear 18 drives the first bevel gear 17 to rotate, the first bevel gear 17 drives the threaded rod 11 to rotate, the threaded rod 11 pushes the slider 12 to move, the slider 12 drives the scraper 13 to move, the scraper 13 fits the outer surface of the heat sealer 9 to clean the sticky residue on its surface.
