[0036] like Figure 1-8 As shown, a disinfection and sealing device of the present invention is applied to a filling barrel, comprising a conveyor belt 100 for conveying the filled filling barrel, a disinfection unit and a sealing unit are sequentially arranged along the conveying direction of the conveyor belt 100, the disinfection unit comprises a mounting frame 200 arranged on the conveyor belt 100, a centering fixing component 6 arranged on the mounting frame 200 for positioning the filling barrel, an outer barrel mouth disinfection component 4 and an inner barrel mouth disinfection component 5 respectively used for disinfecting the outer side and the inner side of the barrel mouth of the positioned filling barrel;

[0037] The sealing unit includes a sealing mechanism 201 disposed on the mounting frame 200 for sealing the sterilized filling barrel.

[0038] In a specific implementation, the filling barrels are sequentially conveyed to the disinfection unit on the conveyor belt 100. When the filling barrel placed in the disinfection unit moves to the bottom of the outer barrel mouth disinfection assembly 4, the lifting unit is operated to drive the outer barrel mouth disinfection assembly 4 to move to the filling barrel to disinfect the outside of the barrel mouth, and the inner barrel mouth disinfection assembly 5 is extended into the inner side of the barrel mouth for disinfection, thereby achieving a synchronous disinfection effect. Before the disinfection operation, the barrel body of the filling barrel conveyed on the conveyor belt 100 is centered and fixed by moving the centering and fixing assembly 6, thereby achieving the accuracy of the positioning disinfection of the outer barrel mouth disinfection assembly 4 and the inner barrel mouth disinfection assembly 5. After the disinfection is completed, the conveyor belt 100 is started to convey the disinfected filling barrel into the sealing area, and the sealing mechanism 201 is operated to perform the sealing process. At the same time, the filling barrel on the front side of the mounting frame 200 will continue to move to the disinfection unit to perform targeted disinfection of the barrel mouth according to the above operation.

[0039] It should be noted that a photoelectric sensor group is provided on the front side of the mounting frame 200 close to the conveying direction of the conveyor belt 100, which is used to stop the conveyor belt 100 after detecting that the filling barrel enters the disinfection unit, so that the filling barrel entering the disinfection unit can be disinfected.

[0040] In one embodiment, a lifting unit is provided on the mounting frame 200, and the lifting unit includes an upper support block 1 provided at the top of the mounting frame 200, a first driving screw rod 2 driven by a motor provided on the upper support block 1, and a linear guide rod 3 symmetrically distributed with the first driving screw rod 2 is provided on the upper support block 1. In this design, by starting the motor, driving the first driving screw rod 2 to rotate, and under the guide limit of the linear guide rod 3 installed on the other side of the upper support block 1, the outer barrel mouth disinfection component 4, the inner barrel mouth disinfection component 5 and the centering fixing component 6 connected at the lower end are adjusted for vertical lifting.

[0041] In one embodiment, the outer barrel mouth disinfection assembly 4 includes two side frames 41 respectively adapted to be arranged on the first driving screw 2 and the linear guide rod 3, and an outer ring cover 42 arranged at the lower ends of the two side frames 41 and used to be sleeved on the outside of the barrel mouth of the filling barrel, and the inner cavity of the peripheral surface of the outer ring cover 42 is provided with a spiral conveying channel 43 and an air flow duct 44 connected to the top channel of the spiral conveying channel 43, and the inner peripheral surface of the outer ring cover 42 is evenly provided with a plurality of air outlets 45 for guiding out high-temperature hot air;

[0042] A hot air device for generating high-temperature hot air is provided at the upper end of the airflow duct 44. With such a design, through the spiral conveying channel 43 separated by spiral blades opened in the inner cavity of the outer ring cover 42, when the hot air device is started, the generated high-temperature hot air enters the spiral conveying channel 43 through the airflow duct 44 and under the spiral structure of the spiral conveying channel 43, the high-temperature hot air flow exhibits a rotating characteristic in the outer ring cover 42, providing additional kinetic energy, and is evenly distributed at several air outlets 45 uniformly passing through the inner peripheral surface of the outer ring cover 42 through the turning process, ensuring that the flow rate of the high-temperature hot air in each part of the inner side of the outer ring cover 42 is consistent, and the high-temperature disinfection effect on the outer wall of the barrel mouth is good;

[0043] The first drive screw 2 and the linear guide rod 3 are respectively adapted and installed on the two side frames 41 welded at both ends of the outer ring cover 42, wherein the first drive screw 2 is threadedly adapted and installed with the corresponding side frame 41, and the linear guide rod 3 is slidably connected with the corresponding side frame 41 through the grooves machined by turning.

[0044] In one embodiment, the inner barrel mouth disinfection assembly 5 includes a bracket 51 arranged on the top surface of the outer ring cover 42, and a first outer gear ring 52 rotatably arranged at the lower part of the bracket 51, and an ultraviolet lamp 53 for ultraviolet disinfection is arranged at the lower part of one side of the first outer gear ring 52. A first rack 54 is guided on the bracket 51 to drive the first outer gear ring 52 and the ultraviolet lamp 53 installed on one side of the first outer gear ring 52 to move in a circular motion, and a fixed block 55 is arranged at the outer end of the first rack 54, and a screw rod 56 is rotatably arranged on the fixed block 55. In this design, through the bracket 51 welded on the top surface of the outer ring cover 42, and the first outer gear ring 52 rotatably installed in the groove on the lower surface of the bracket 51, when the first rack 54 is subjected to an external force to generate a driving force for lateral translation, the first outer gear ring 52 meshing with the tooth surface of the first rack 54 will perform a circular motion, driving the ultraviolet lamp tube 53 embedded in the groove on one side of the first outer gear ring 52 to rotate during the downward movement, so as to perform ultraviolet sterilization and disinfection operations on the inner side of the barrel mouth, ensuring the sterilization operation without dead angles on the inner side of the barrel mouth;

[0045] A screw rod 56 adapted and installed in a fixed block 55 welded to the lower part of the outer end of the first rack 54 and in a threaded groove machined on the fixed block 55 is rotated.

[0046] In one embodiment, a first transmission unit 7 which is transmission-connected to the screw rod 56 is disposed at a lower section of the first driving screw rod 2;

[0047] The first transmission unit 7 includes a worm 71 arranged at a lower section of the first driving screw 2, and a worm wheel 72 meshingly arranged on the side of the worm 71, a first pulley 73 is coaxially arranged on the worm wheel 72, a first transmission belt 74 is arranged on the first pulley 73, and a second pulley 75 is wound around the other end of the first transmission belt 74, and the second pulley 75 is fixedly mounted corresponding to the screw 56. With this design, a worm 71 is machined on a lower section of the first driving screw 2 and meshed with a worm wheel 72 on the side of the worm 71. When the first driving screw 2 rotates, the worm 71 is driven to rotate, so that the worm wheel 72 meshed on the side of the worm 71 rotates, and then the force is transmitted to the second pulley 75 through the first pulley 73 coaxially mounted on the worm wheel 72 and the first transmission belt 74 wound around the first pulley 73, driving the screw 56 mounted on the center of the end face of the second pulley 75 to rotate, and the fixed block 55 mounted outside the screw 56 and the first rack 54 welded on the fixed block 55 perform linear motion under the guide limit of the bracket 51, driving the ultraviolet lamp 53 installed on one side of the first outer gear ring 52 to move in a circle.

[0048] It should be noted that the high-temperature disinfection and ultraviolet disinfection operations are both performed during the downward movement of the outer barrel mouth disinfection component 4 and the inner barrel mouth disinfection component 5, which improves the efficiency of disinfection and sterilization.

[0049] In one embodiment, the centering and fixing assembly 6 comprises a support plate 61 slidably mounted on the vertical surface of the mounting frame 200, a support ring 62 mounted on the support plate 61, and a fixing unit 63 mounted on the support ring 62 and used to center and fix the filling barrel. With such a design, the support plate 61 slidably mounted on the vertical surface of the mounting frame 200 through the slots, the support ring 62 welded on the end of the support plate 61 away from the disinfection unit, and the fixing unit 63 mounted on the upper surface of the support ring 62 through the slots, can be moved before the disinfection operation, so that the support ring 62 is covered on the outside of the barrel body, and the barrel body of the filling barrel transported on the conveyor belt 100 is fixed in the center under the centering clamping of the fixing unit 63, so as to ensure that during the disinfection process, the outer ring cover 42 that moves downward can be accurately covered on the outside of the barrel mouth.

[0050] In one embodiment, the fixing unit 63 includes a second outer gear ring 631 rotatably arranged on the upper part of the support ring 62, and the second outer gear ring 631 is externally meshed with symmetrically distributed first gears 632 on both sides, and the first gear 632 is coaxially arranged with a second gear 633, and the second gear 633 is meshed with a second rack 634, and the inner end of the second rack 634 is fixed with an arc-shaped clamping block 635. In this design, through the second outer gear ring 631 rotatably installed in the groove on the upper surface of the support ring 62, and the first gear 632 and the second gear 633 coaxially installed on both sides of the second outer gear ring 631 that are meshed and connected externally, when the second outer gear ring 631 is driven by an external force, it will drive the two symmetrically distributed first gears 632 on the outer side of the second outer gear ring 631 to rotate synchronously, so that the second gear 633 coaxially installed on the lower side of the first gear 632 rotates, and then drives the second rack 634 meshing on the side of the second gear 633 and the arc-shaped clamping block 635 integrally formed at the inner end of the second rack 634 to move inward synchronously, and the resulting centering clamping effect can ensure the centering of the filling barrel, which is beneficial to the subsequent positioning and disinfection operations of the outer barrel mouth disinfection component 4 and the inner barrel mouth disinfection component 5.

[0051] It should be noted that the second rack 634 is slidably installed in a turning groove on the circumferential surface of the support ring 62.

[0052] In one embodiment, the first driving screw rod 2 is provided with a second transmission unit 8 which is transmission-connected to the second outer gear ring 631;

[0053] The second transmission unit 8 includes a third gear 81 disposed on one side of the support ring 62 and meshing with the second outer gear ring 631, a guide rod 82 disposed on the third gear 81 and used for coaxial rotation, a third pulley 83 is vertically movable on the guide rod 82, a second transmission belt 84 is disposed on the outer periphery of the third pulley 83, and a fourth pulley 85 is wound around the other end of the second transmission belt 84;

[0054] The fourth pulley 85 is sleeved on the first driving screw 2 near the lower end of the worm 71. In this design, by installing the third gear 81 meshing with the second outer gear ring 631 at the position other than the two second gears 633 installed on the support ring 62, and the guide rod 82 sleeved and fixed on the end face of the third gear 81 and the groove surface machined on the outer wall of the guide rod 82 vertically slidingly connecting the third pulley 83, when the fourth pulley 85 wound around the other end of the second transmission belt 84 wound around the third pulley 83 rotates with the first driving screw 2, the generated force will be transmitted to the third gear 81 through the guide rod 82 installed on the third pulley 83, driving the second outer gear ring 631 meshing on the outer side of the third gear 81 to rotate, generating a power rotation effect for the fixing unit 63, achieving a centering clamping effect, and ensuring the fixing effect of the barrel body of the filling barrel.

[0055] It should be noted that, during the initial design, the height of the bottom surface of the support ring 62 and the top surface of the outer ring cover 42 will be preset based on the distance from the barrel mouth to 1 / 5 of the barrel body, to ensure that during the downward movement, the support ring 62 will move the outer ring cover 42 to the filling barrel first, until it moves to the target position on the filling barrel in turn, and the relative displacement of the two arc-shaped clamping blocks 635 included in the fixing unit 63 is equal to the stroke of the outer ring cover 42 from the top of the barrel mouth to the bottom of the through opening.

[0056] It should be noted that the third pulley 83, which is vertically slidably connected to the groove surface machined on the outer wall of the guide rod 82, will not interfere with the transmission effect of the subsequent second transmission unit 8 due to the vertical sliding phase shift of the guide rod 82 and the third pulley 83 during the vertical movement of the centering fixed component 6.

[0057] In one embodiment, the support plate 61 is adapted to be rotatably provided with a second driving screw 9 driven by a motor;

[0058] The second drive screw 9 is used to drive the support plate 61 and the structure installed on the support plate 61 to move vertically and linearly. With this design, by rotating the second drive screw 9 adapted to be installed in the through groove machined on the support plate 61, when the motor installed on the coupling at the upper end of the second drive screw 9 is started, the support plate 61 adapted to be installed on the second drive screw 9 and the structure installed on the support plate 61 will be driven to move linearly under the slotted limit of the vertical surface of the mounting frame 200, and the centering fixing component 6 will be moved to be placed on the barrel body of the filling barrel, and the outer barrel mouth disinfection component 4 and the inner barrel mouth disinfection component 5 will be moved downward in the subsequent operation to perform centering and fixing, so as to facilitate the outer barrel mouth disinfection component 4 and the inner barrel mouth disinfection component 5 to be aligned with the barrel mouth for disinfection.

[0059] In one embodiment, the upper support block 1 is provided with a screw mechanism that drives it to move linearly at the top of the mounting frame 200. With this design, the upper support block 1 and the related structures installed on the upper support block 1 can be horizontally moved at the top of the mounting frame 200 through the screw mechanism installed in the groove machined on the upper support block 1, and the horizontal position can be adjusted within a limited range in the mounting frame 200, which helps to improve the accuracy of in-situ disinfection and is conducive to improving the efficiency of disinfection.

[0060] It should be noted that the upper support block 1 installed on the top of the mounting frame 200 can be adjusted in horizontal position to avoid misalignment between the filling barrel transported on the conveyor belt 100 and the outer barrel mouth disinfection component 4, the inner barrel mouth disinfection component 5, and the centering fixing component 6 installed in the disinfection unit.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
