DETAILED DESCRIPTION

[0017] The embodiment of the present application discloses a high-efficiency heat-sealing roller for medical sterilization bags, which limits the packaging bag by rotating the lower heat-sealing roller 20 through two limiting plates 41, so that the offset packaging bag can be moved to the center position, thereby improving the accuracy of heat pressing.

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0019] Please refer to Figure 1 、 Figure 2 and Figure 3 The present embodiment provides a high-efficiency heat-sealing pressure roller for medical sterilization bags, including a lower heat-sealing roller 20 rotatably connected between two support plates 10, wherein a motor 60 is fixedly provided on one side of one support plate 10, and the output shaft of the motor 60 is fixedly connected to the lower heat-sealing roller 20, and a heat-sealing mechanism 30 is provided on the top of the two support plates 10. The heat-sealing mechanism 30 includes an upper heat-sealing roller 31, a connecting seat 32, a fixed seat 33, and a reciprocating assembly 34. The upper heat-sealing roller 31 is arranged on the top of the lower heat-sealing roller 20, the connecting seat 32 is arranged on the outer side of the upper heat-sealing roller 31, the fixed seat 33 is arranged on the top of the two lower heat-sealing rollers 20, and the reciprocating assembly 34 is arranged on the top of the connecting seat 32. The reciprocating assembly 34 includes a reciprocating screw 341, a movable sleeve 342, a driving motor 343, and a telescopic rod 344. The reciprocating screw 341 is rotatably connected to the bottom of the fixed seat 33, the movable sleeve 342 is sleeved and threadedly connected to the outer side of the bottom of the reciprocating screw 341, and the movable sleeve 34 The two extension rods 344 are fixedly connected to the connecting seat 32, and the rotation of the reciprocating screw 341 drives the movable sleeve 342 to move up and down. The extension and contraction of the two extension rods 344 limit the movement of the movable sleeve 342 to prevent the movable sleeve 342 from rotating with the reciprocating screw 341. The upper heat sealing roller 31 at the bottom of the movable sleeve 342 reciprocates up and down and the motor 60 drives the lower heat sealing roller 20 to rotate, so that the pressure produces deformation to complete the heat sealing of the sterilization bag. The cycle of the movable sleeve 342 driven by the reciprocating screw 341 and the speed of the lower heat sealing roller 20 are constant, so that the upper heat sealing roller 31 can heat press the sterilization bag at equal intervals, making the heat sealing process more accurate.

[0020] Please refer to Figures 1-4, a limit assembly 40 is provided at the bottom of the lower heat sealing roller 20, and a slide groove 50 is opened at the bottom of the lower heat sealing roller 20. The limit assembly 40 includes a limit plate 41, a bidirectional screw 42, a movable block 43, and a reduction motor 44. The two limit plates 41 are respectively slidably connected to the two sides of the bottom of the lower heat sealing roller 20, and the two ends of the inner side of the two limit plates 41 are arc surfaces. The bidirectional screw 42 is rotatably connected to the inside of the slide groove 50, and the two movable blocks 43 are sleeved and threadedly connected to the two ends of the outer side of the bidirectional screw 42, and the bottoms of the two movable blocks 43 are respectively fixedly connected to the two limit plates 41, and the reduction motor 44 is fixedly installed inside the lower heat sealing roller 20, and the output shaft of the reduction motor 44 is fixedly connected to the bidirectional screw 42. The two limit plates 41 rotate with the lower heat-sealing roller 20, so that when the two limit plates 41 rotate to the top position, the two limit plates 41 can limit the sterilization bag, and the arc surfaces inside the two limit plates 41 can contact the slightly offset sides of the sterilization bag, so that the sterilization bag can be placed in the center position to prevent the sterilization bag from offsetting and affecting the accuracy of heat sealing. When the two limit plates 41 move to the top, the upper heat-sealing roller 31 does not fall for heat sealing, which prevents the limit plates 41 from colliding with the upper heat-sealing roller 31. The two limit plates 41 are driven to move toward each other by the rotation of the bidirectional lead screw 42, thereby changing the distance between the two limit plates 41, so that the lower heat-sealing roller 20 can adapt to sterilization bags of different widths, thereby improving the applicability of the device.

[0021] This application can explain its functional principles through the following operation methods:

[0022] When in use, the reduction motor 44 inside the lower heat-sealing roller 20 is started, so that the output shaft of the reduction motor 44 drives the bidirectional screw 42 inside the slide 50 to rotate, and the rotation of the bidirectional screw 42 drives the two movable blocks 43 threadedly connected thereto at both ends to move toward each other, thereby changing the distance between the two limit plates 41, so that the two limit plates 41 can adjust the spacing according to sterilization bags of different widths. The winding mechanism places one end of the sterilization bag on the top of the lower heat-sealing roller 20, starts the motor 60 on one side of the support plate 10 and the drive motor 343 inside the fixed seat 33, and the output shaft of the motor 60 drives the lower heat-sealing roller 20 to rotate, so that the sterilization bag moves accordingly, and the output shaft of the drive motor 343 drives the reciprocating screw 341 to rotate, thereby driving the bottom of the reciprocating screw 341 The movable sleeve 342 threadedly connected to it moves up and down, and the two telescopic rods 344 limit the movement of the movable sleeve 342. Before the movable sleeve 342 drives the connecting seat 32 and the upper heat-sealing roller 31 to move downward, the lower heat-sealing roller 20 drives the two limiting plates 41 at the bottom to move to the top position. The arcs on the inner sides of the two limiting plates 41 contact the offset sides of the sterilization bag, thereby limiting the position of the sterilization bag to prevent the sterilization bag from being skewed. When the upper heat-sealing roller 31 moves downward, the two limiting plates 41 move to the bottom of the lower heat-sealing roller 20, and the downward movement of the upper heat-sealing roller 31 cooperates with the rotation of the lower heat-sealing roller 20 to heat-seal the sterilization bag. With the up and down reciprocating movement of the upper heat-sealing roller 31 and the uniform rotation of the lower heat-sealing roller 20, multiple sterilization bags are heat-sealed at equal intervals.

[0023] Obviously, those skilled in the art may make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.

[0024] The above is only a preferred specific implementation method of the embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
