Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached Figures 1-6 drawings in the embodiments of the present invention.

[0027] Please refer to Figures 1-6 , in the embodiment of the present utility model, a kraft paper wrapping device includes a device body 1, a box body 5 filled with absorbent cotton inside, and a cotton block 14 arranged at the opening of the box body 5, a partition plate 20 which divides the device body 1 into a first cavity 21 and a second cavity 22, a winding shaft 2 rotatably connected to the partition plate 20, and the winding shaft 2 in the second cavity 22 is configured to wind a kraft paper roll, a support plate 7 which is fixed in the second cavity 22, a second bevel gear 13 rotatably connected to the support plate 7, a threaded rod 8 passing through and threadedly connected to the second bevel gear 13, the threaded rod 8 is movably arranged on the support plate 7, a rotating shaft 11 rotatably connected to the partition plate 20, a first bevel gear 12 sleeved on the rotating shaft 11 and meshing with the second bevel gear 13, a belt transmission mechanism 6 is connected between the rotating shaft 11 and the winding shaft 2, a pressing plate 17 which is movably arranged in the box body 5, a movable plate 10 movably connected to the box body 5, one end of the movable plate 10 is fixedly connected to the pressing plate 17, and the other end is rotatably connected to the threaded rod 8.

[0028] Specifically, the box body 5 is filled with absorbent cotton adsorbed with water, and the absorbent cotton contacts the cotton block 14 at the opening of the box body 5. When it is necessary to use the kraft paper roll for wrapping, pull the kraft paper roll to move outward along the outlet direction of the device body 1, so that the kraft paper roll drives the winding shaft 2 to rotate. At the same time, under the action of the belt transmission mechanism 6, the rotating shaft 11 is driven to rotate, and the first bevel gear 12 on the rotating shaft 11 rotates accordingly. Since the first bevel gear 12 meshes with the second bevel gear 13, the second bevel gear 13 also starts to rotate. The rotation of the second bevel gear 13 causes the threaded rod 8 threadedly connected to it to move on the support plate 7, so that the threaded rod 8 drives the pressing plate 17 to move in the box body 5 towards the opening of the box body 5 through the movable plate 10. The pressing plate 17 squeezes the absorbent cotton in the box body 5, so that the water in the absorbent cotton in the box body 5 is discharged to the cotton block 14 to ensure the overall humidity of the cotton block 14. The overall automation degree is high, and the humidity of the cotton block 14 in the box body 5 can be maintained when the kraft paper roll is pulled, making the wetting of the kraft paper more uniform and ensuring subsequent use.

[0029] It should be noted that, in this embodiment, the connection between the device body 1 and the box body 5, the use of the device body 1, etc. can all refer to a kraft paper wrapping device with a patent publication number of CN218172807U; secondly, there are two support plates 7, and the two support plates 7 are oppositely arranged in the second cavity 22 of the device body 1. The threaded rod 8 is movably arranged on the two support plates 7, and the movement of the threaded rod 8 is realized by the rotation of the second bevel gear 13. At the same time, the installation method of the belt transmission mechanism 6 is a prior art.

[0030] In the embodiment of the present utility model, as Figure 3 and Figure 4As shown, the diameter of the first bevel gear 12 is smaller than the diameter of the second bevel gear 13. Specifically, the rotation ratio between the winding shaft 2 and the threaded rod 8 is changed. This has the advantage that the speed of movement of the extrusion plate 17 can be adjusted more accurately.

[0031] In the embodiment of the utility model, Figure 3 As shown, a connecting plate 9 is provided between the threaded rod 8 and the movable plate 10, and the threaded rod 8 is rotatably set on the connecting plate 9. The movable plate 10 is a square structure. Specifically, the movable plate 10 is a square structure. This shape can better cooperate with the box body 5 to ensure the stability of the movable plate 10 during movement; the end of the threaded rod 8 away from the connecting plate 9 is fixedly connected with a positioning plate 23, and the positioning plate 23 can prevent the threaded rod 8 from excessive movement and play a limiting role.

[0032] In the embodiment of the utility model, Figure 5 As shown, a first sealing gasket 18 is fixedly connected between the extrusion plate 17 and the inner wall of the box body 5, and a second sealing gasket 19 is fixedly connected at the interface between the movable plate 10 and the box body 5. Specifically, multiple groups of sealing gaskets can prevent water in the box body 5 from leaking out and ensure the sealing of the device.

[0033] In the embodiment of the utility model, Figure 5 and Figure 6 As shown, a plurality of limit members 15 for supporting the cotton block 14 are fixedly connected inside the box body 5, and the plurality of limit members 15 are arranged at intervals at the opening of the box body 5. The limit members 15 are composed of a limit plate 151 fixedly connected to the box body 5 and limit cones 152 relatively arranged on both sides of the limit plate 151, and there are multiple limit cones 152 that are evenly arranged on the limit plate 151. A cotton rope 16 is fixedly connected to the bottom of the cotton block 14, and one end of the cotton rope 16 that is away from the cotton block 14 extends to the bottom of the inner wall of the box body 5. Specifically, the limit member 15 can fix the position of the cotton block 14 to prevent the cotton block 14 from moving during use. At the same time, it can also prevent the absorbent cotton in the box body 5 from being squeezed out of the opening of the box body 5, and avoid the cotton block 14 from loosening due to excessive squeezing force. Secondly, the cotton rope 16 can further ensure that the water in the box body 5 is absorbed by the cotton block 14.

[0034] In the embodiment of the utility model, Figure 1 and Figure 2 As shown, a base 3 is fixedly connected to the bottom of the device body 1, and a cover plate 4 is detachably connected to both sides of the device body 1. Specifically, the base 3 can improve the stability of the device and facilitate placement and use. The setting of the cover plate 4 facilitates the subsequent maintenance of the device body 1 and the replacement of parts. The cover plate 4 is at both ends and respectively forms a first cavity 21 and a second cavity 22 with the device body 1 together with the partition 20.

[0035] Working principle: When it is necessary to use the kraft paper roll for wrapping, pull the kraft paper roll to move outward along the outlet direction of the device body 1, so that the kraft paper roll drives the winding shaft 2 to rotate. At the same time, under the action of the belt transmission mechanism 6, the rotating shaft 11 is driven to rotate, and the first bevel gear 12 on the rotating shaft 11 rotates accordingly. Since the first bevel gear 12 meshes with the second bevel gear 13, the second bevel gear 13 also starts to rotate. The rotation of the second bevel gear 13 causes the threaded rod 8 threadedly connected to it to move on the support plate 7, so that the threaded rod 8 drives the pressing plate 17 through the movable plate 10 to move in the box body 5 towards the opening direction of the box body 5. The pressing plate 17 presses the water-absorbing cotton in the box body 5, so that the moisture in the water-absorbing cotton in the box body 5 is discharged to the cotton block 14 to ensure the overall humidity of the cotton block 14. The overall automation degree is high, and the humidity of the cotton block 14 in the box body 5 can be maintained when the kraft paper roll is pulled, making the wetting of the kraft paper more uniform and ensuring subsequent use.
