[0042] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0043] Please refer to the following: Figures 1 to 10The present invention provides a bandage roll packaging device. The bandage roll packaging device includes a workbench 1, a heat-sealing and cutting mechanism 2, a one-way tube 3, and a vacuuming mechanism. The workbench 1 has a feeding channel; an upper film conveying mechanism 4 and a lower film conveying mechanism 5 are provided on the workbench 1, the upper and lower films are arranged vertically along the feeding channel and aligned with each other; a bandage roll is placed between the upper and lower films; the heat-sealing and cutting mechanism 2 is disposed on the workbench 1; the heat-sealing and cutting mechanism 2 is used to heat-seal the upper and lower films around the bandage roll, and is used for... The heat-sealed area is cut; the workbench 1 has a discharge port 11 at the position corresponding to the heat-sealing and cutting mechanism 2, and the discharge port 11 is equipped with a sealing plate 12, which is used to open or close the discharge port 11; a one-way tube 3 is set between the upper film and the lower film for heat sealing between the upper film and the lower film; the gas around the bandage roll can be discharged through the one-way tube 3; the vacuuming mechanism includes a sealing shell 6 for covering the upper film, the lower film and the bandage roll, and the sealing shell 6 is connected to an air extraction structure (not shown in the figure) through a pipe. The material of the one-way tube 3 is the same as the material of the upper film and the lower film; the air extraction structure includes a pipe connected to the sealing shell 6 and a vacuum pump, and the vacuum pump is connected to the other end of the pipe; when the vacuum pump is started, the air inside the sealing shell 6 can be extracted.

[0044] This invention provides a bandage roll packaging device. Compared with the prior art, before the upper and lower films are aligned, the lower film has a feeding position, which facilitates placing the bandage roll on the lower film. When the lower film moves to the position aligned with the upper film, the bandage roll is located between the upper and lower films. After the bandage roll moves to the designated position, a one-way tube 3 is placed between the upper and lower films, and the area around the bandage roll is heat-sealed by a heat-sealing and cutting mechanism 2. The heat-sealed area is then cut to form a packaging bag. After cutting, the one-way tube 3 is connected to the packaging bag. The sealing shell 6 moves downward and seals the packaging bag. Then, the air inside the sealing shell 6 is extracted by a vacuum structure, allowing the air inside the packaging bag to be discharged, thereby achieving the purpose of vacuum packaging. Through the above-described configuration of this application, the amount of air inside the packaging bag can be reduced after the bandage roll is packaged.

[0045] It should be noted that an upwardly extending extension frame 13 is fixedly provided on the worktable 1. The upper film conveying mechanism 4 includes a rotating shaft rotatably mounted on the extension frame 13 and a drive motor for driving the rotating shaft to rotate. The rotating shaft on the extension frame 13 is used to engage with the upper film roll. When the drive motor drives the rotating shaft to rotate, the upper film roll can rotate accordingly. The lower film conveying mechanism 5 has the same structure as the upper film conveying mechanism 4, and will not be described in detail here. The difference between the lower film conveying mechanism 5 and the upper film conveying mechanism 4 is the installation position. The lower film conveying mechanism 5 is located on one side of the worktable 1 and is lower than the upper film conveying mechanism 4. A limiting structure (not shown in the figure) for laterally limiting the material roll is provided on the rotating shaft. The above-mentioned limiting structure is prior art and will not be described in detail here. The worktable 1 is equipped with a winding frame (not shown in the figure) at the end of the movement direction of the upper and lower film. A winding shaft is rotatably mounted on the winding frame, and a drive motor for driving the winding shaft to rotate is also mounted on the winding frame. After the upper and lower film waste is cut, it is wound onto the winding shaft to recycle the waste. Through the cooperation of the winding shaft and the rotating shaft, the upper and lower film can be driven to move on the worktable 1.

[0046] In addition, a one-way valve core is installed inside the one-way tube 3. The one-way valve core is existing technology and will not be described in detail here. After installing the one-way valve core inside the one-way tube 3, the one-way tube 3 can have a one-way conduction function. Therefore, after the one-way tube 3 is heat-sealed onto the packaging bag, the air inside the packaging bag can be discharged through the one-way tube 3.

[0047] In some embodiments, such as Figures 1 to 10 As shown, the heat-sealing and cutting mechanism 2 includes a heat-sealing frame 21 disposed within the sealing shell 6, and a first driving mechanism 22 for driving the heat-sealing frame 21 to slide up and down; the bottom of the heat-sealing frame 21 has a clearance groove 211 for avoiding the one-way tube 3; the heat-sealing frame 21 is provided with a heating structure (not shown in the figure) to heat-seal the upper film and the lower film; the first driving mechanism 22 is connected to the sealing shell 6, and the telescopic end of the first driving mechanism 22 is connected to the heat-sealing frame 21. The first driving mechanism 22 includes a cylinder.

[0048] It should be noted that the heating structure on the heat-sealing frame 21 can be an electric heating wire, which is existing technology and will not be described in detail here. When the bandage roll moves to directly below the heat-sealing frame 21, the one-way tube 3 is placed between the upper and lower films and aligned with the clearance groove 211 on the heat-sealing frame 21. The heat-sealing frame 21 slides downward under the driving action of the first driving mechanism 22 and finally heat-seales the upper and lower films. At the same time, the one-way tube 3 is also heat-sealed between the upper and lower films. Then, the heat-sealed position is cut to separate the heat-sealed part, and the one-way tube 3 is located in the heat-sealed part. One end of the one-way tube 3 is connected to the outside, and the other end of the one-way tube 3 is connected to the inside of the packaging bag. When vacuuming, the air inside the packaging bag can be extracted.

[0049] In some embodiments, such as Figures 1 to 10 As shown, the bandage roll packaging equipment also includes a pushing mechanism 7 for pushing the one-way tube 3. The pushing mechanism 7 includes a guide shell 71 and a pushing force member 72. The guide shell 71 is set on the worktable 1. The axial direction of the guide shell 71 is perpendicular to the movement direction of the upper film. The top of the guide shell 71 has an opening for placing the one-way tube 3. The pushing force member 72 is connected to the guide shell 71. The pushing end of the pushing force member 72 passes through the guide shell 71 and is used to push the one-way tube 3 inside the guide shell 71. The pushing end is provided with an elastic member 73 for engaging the inner or outer wall of the one-way tube 3.

[0050] It should be noted that the pushing force component 72 is either a cylinder or an electric push rod; this embodiment uses an electric push rod as an example. After the one-way tube 3 is placed inside the guide shell 71, the elastic component 73 positions the one-way tube 3 relative to the pushing end, and the electric push rod pushes the one-way tube 3 between the upper and lower films. During the heat sealing process of the heat sealing frame 21 on the upper film, lower film, and one-way tube 3, the pushing end of the electric push rod returns to its original position. Due to the pressing action of the heat sealing frame 21, the one-way tube 3 does not move, and the elastic component 73 slides backward relative to the one-way tube 3. Therefore, the elastic component 73 can separate from the one-way tube 3 and eventually move backward to its initial position. With the above-mentioned configuration of this application, on the one hand, it is convenient to transport the one-way tube 3 between the upper and lower films, and on the other hand, the one-way tube 3 can be positioned during the heat sealing process.

[0051] In some embodiments, such as Figures 1 to 10 As shown, the pushing end of the pushing force member 72 is provided with a top plate 721, and the elastic member 73 includes a number of elastic strips spaced apart along the circumference of the top plate 721. One end of each elastic strip is fixed on the top plate 721, and the other end is a free end. Each elastic strip is used to contact the inner circumferential wall of the one-way tube 3, and the free end of each elastic strip is provided with a guide surface for insertion and mating with the one-way tube 3.

[0052] It should be noted that a baffle 14 is slidably provided on the worktable 1. The baffle 14 is driven by a cylinder (not shown in the figure), which is fixed on the worktable 1. After the one-way tube 3 is placed in the guide shell 71, one end of the one-way tube 3 is in contact with the baffle 14. Then, the electric push rod pushes the top plate 721 to slide, so that the top plate 721 contacts the other end of the one-way tube 3 and inserts the elastic strip into the one-way tube 3. At this time, the elastic strip contacts the inner wall of the one-way tube 3 and provides an outward expansion elastic force to the inner wall of the elastic tube. Then, the baffle 14 slides out of the guide shell 71, and the one-way tube 3 slides between the upper film and the lower film under the drive of the electric push rod, and is located directly below the relief groove 211 of the heat sealing frame 21, so that the heat sealing frame 21 can heat seal the one-way tube 3 between the upper film and the lower film.

[0053] For example, since a guide surface is provided on the elastic strip, it is easy for the elastic strip to be inserted into the one-way tube 3; since the elastic strip is elastic, after the elastic strip is inserted into the elastic tube, the elastic strip will undergo elastic deformation, and the elastic strip not only contacts the inner wall surface of the one-way tube 3, but also provides an outward expansion elastic force to the inner wall surface of the one-way tube 3.

[0054] In some embodiments, such as Figures 1 to 10 As shown, a loading rack 8 is provided above the guide shell 71 on the worktable 1. The loading rack 8 is used to stack several unidirectional tubes 3 along the height direction. The bottom of the loading rack 8 is connected to the worktable 1, and the bottom of the loading rack 8 has an opening and closing structure for opening or closing the bottom of the loading rack 8. The opening and closing structure includes an opening and closing plate 81 and a starting cylinder (not shown in the figure). The starting cylinder is fixed to the loading rack 8, or it can be fixed to the worktable 1. The piston rod of the starting cylinder is connected to the opening and closing plate 81 to drive the opening and closing plate 81 to open or close the bottom of the loading rack 8. The loading rack 8 is provided with a sliding groove for sliding cooperation with the opening and closing plate 81.

[0055] It should be noted that when the opening and closing plate 81 opens the bottom of the feeding rack 8, the one-way tubes 3 inside the feeding rack 8 fall downwards, and only the bottom one-way tube 3 falls into the guide shell 71; then the opening and closing plate 81 closes the bottom of the feeding rack 8, providing support for the remaining one-way tubes 3 inside the feeding rack 8. Through the above-mentioned settings of this application, it can be ensured that only one one-way tube 3 is pushed at a time.

[0056] In some embodiments, such as Figures 1 to 10 As shown, the worktable 1 is provided with a fine-tuning structure 9 for fine-tuning the position of the guide shell 71. The fine-tuning structure 9 includes a rack 91, a gear 92 and a drive motor 93. The rack 91 is connected to the guide shell 71. The gear 92 meshes with the rack 91. The drive motor 93 is fixed on the worktable 1. The output shaft of the drive motor 93 is connected to the gear 92 to drive the gear 92 to rotate.

[0057] It should be noted that a guide plate 74 is fixedly provided on the outer wall of the guide shell 71, and an L-shaped plate 75 is provided on the worktable 1. The two L-shaped plates 75 cooperate to limit the sliding direction of the guide shell 71. The worktable 1 has a placement slot 15 for placing the drive motor 93 and the gear 92. The drive motor 93 drives the gear 92 to rotate, and the meshing of the gear 92 with the rack 91 allows for fine adjustment of the position of the guide shell 71.

[0058] In some embodiments, such as Figures 1 to 10As shown, the heat-sealing and cutting mechanism 2 also includes a cutting frame 23 and a second driving mechanism 24; the cutting frame 23 is sleeved on the heat-sealing frame 21 and has the freedom to slide along the height direction; the second driving mechanism 24 is connected to the sealing shell 6; the pushing end of the second driving mechanism 24 is connected to the cutting frame 23.

[0059] It should be noted that the second drive mechanism 24 includes a cylinder, which is fixed to the sealing shell 6. By driving the cutting frame 23 to slide downwards via the cylinder, the cutting frame 23 can cut the heat-sealed area to form a packaging bag. The worktable 1 has inclined surfaces 111 around the discharge port 11 to form a cutting clearance groove 211, which facilitates the cutting frame 23 to cut the heat-sealed area.

[0060] In some embodiments, such as Figures 1 to 10 As shown, the vacuuming mechanism also includes a third drive mechanism, which is set on the worktable 1; the lifting end of the third drive mechanism is connected to the sealing shell 6 to drive the sealing shell 6 to rise and fall.

[0061] It should be noted that the third driving mechanism includes a slider 61, a slide rail 62, and a screw 63. The slider 61 is slidably engaged with the slide rail 62, and the screw 63 is rotatably engaged with the slide rail 62. A drive motor 93 is mounted on the slide rail 62, and the output shaft of the drive motor 93 is connected to one end of the screw 63 to drive the screw 63 to rotate. The slider 61 has a threaded hole that is threadedly engaged with the screw 63. During the rotation of the screw 63, the slider 61 can slide up and down. The slider 61 is fixedly connected to the sealing shell 6, so the sealing shell 6 can rise and fall with the slider 61, achieving the purpose of sealing the upper and lower membranes, or separating the sealing shell 6 from the upper and lower membranes.

[0062] In some embodiments, such as Figures 1 to 10 As shown, a support plate 16 is provided on the workbench 1, and the support plate 16 is slidably disposed on the workbench 1. The workbench 1 has a limiting component 17 for limiting the height of the support plate 16. The upper surface of the support plate 16 is used to contact the lower surface of the sealing plate 12 so that the sealing plate 12 closes the discharge port 11. When the support plate 16 is separated from the sealing plate 12, the sealing plate 12 opens the discharge port 11 under the action of gravity. The support plate 16 is driven by a cylinder.

[0063] It should be noted that the sealing plate 12 is hinged to the outlet 11 of the worktable 1 via a hinge shaft, and the support plate 16 is located at the bottom of the worktable 1 at the hinge shaft. When the support plate 16 slides to contact the lower surface of the sealing plate 12, the sealing plate 12 is in a horizontal state and closes the outlet 11. When the support plate 16 separates from the sealing plate 12, the sealing plate 12 rotates downward around the hinge shaft under the action of gravity and opens the outlet 11, allowing the packaging bag to fall from the outlet 11. A collection box (not shown in the figure) is provided below the outlet 11, and the packaging bag falling from the outlet 11 can be collected by the collection box.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
