DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0023] Aluminum film is a material made from aluminum foil or plastic film coated with an aluminum layer, widely used in various packaging and protective purposes. The drop-resistant aluminum film lined paper drum usually refers to a paper drum with aluminum film as the inner liner. This design is mainly to enhance the structural strength and durability of the paper drum, preventing damage or deformation due to impact or dropping during use.

[0024] In the above method, the adhesion can firmly fix the aluminum film on the inner wall of the paper drum. However, the aluminum film is pasted as a thin film on the inner wall of the paper drum, which will bring the problem of inconvenience in replacement when the aluminum film is broken. The main reason is that the aluminum film is fixed on the inner wall of the paper drum with strong adhesive. When the aluminum film is broken and needs to be replaced, the residue of the old adhesive will increase the difficulty of cleaning and re-pasting. Thoroughly removing the old adhesive in order to re-paste the new aluminum film is a time-consuming and laborious process. Please refer to Figures 1-4 , provides a drop-resistant aluminum film lined paper drum, including a paper drum 1 and a barrel-shaped aluminum film 2 sleeved inside the paper drum 1. By installing a barrel-shaped aluminum film 2 inside the reinforced paper drum structure, the compression and drop resistance of the paper drum 1 can be effectively improved, and the waterproof ability of the paper drum 1 can also be enhanced.

[0025] Reference Figures 2-3As shown, the top of the paper barrel 1 is provided with a bottom ring 3, the top of the barrel-shaped aluminum film 2 is fixedly connected with a ring-shaped aluminum film 21, the top of the bottom ring 3 is provided with a top ring 5, the ring-shaped aluminum film 21 is clamped between the top ring 5 and the bottom ring 3, the barrel-shaped aluminum film 2 is passed through the inside of the bottom ring 3 until the ring-shaped aluminum film 21 contacts the top of the bottom ring 3, the top ring 5 is covered on the top of the bottom ring 3, and then the ring-shaped aluminum film 21 is clamped between the top ring 5 and the bottom ring 3, so as to realize the preliminary positioning of the barrel-shaped aluminum film 2. The bottom of the top ring 5 is provided with an annular groove 53, the inner top wall of the annular groove 53 is fixedly connected with an annular upper magnet 51, the top of the bottom ring 3 is fixedly connected with an annular lower magnet 31 which is attracted to the annular upper magnet 51, the size of the annular upper magnet 51 and the annular lower magnet 31 is the same, and the inner diameters of the annular upper magnet 51 and the annular lower magnet 31 are both larger than the outer diameter of the ring-shaped aluminum film 21. When the top ring 5 and the bottom ring 3 clamp the ring-shaped aluminum film 21, the annular upper magnet 51 and the annular lower magnet 31 are attracted to each other, which can increase the fit of the ring-shaped aluminum film 21 clamped between the top ring 5 and the bottom ring 3, and then improve the positioning firmness. The bottom of the top ring 5 is fixedly connected with a sealing ring 52, the outer wall of the top end of the paper barrel 1 is fixedly connected with a concave ring 11 matched with the sealing ring 52. When the barrel-shaped aluminum film 2 is placed in the paper barrel 1, the sealing ring 52 is clamped with the inside of the concave ring 11, which can further reduce the gap at the junction of the paper barrel 1 and the bottom ring 3, thereby improving the stability and firmness of the barrel-shaped aluminum film 2 sleeved in the paper barrel 1, and then improving the positioning reliability of the barrel-shaped aluminum film 2 installed in the paper barrel 1.

[0026] Reference Figures 2-4As shown, the aluminum film is pasted on the inner wall of the paper barrel 1 as a thin film, and the replacement will be inconvenient when the aluminum film is broken. The main reason is that the aluminum film is fixed on the inner wall of the paper barrel 1 by using strong adhesive. When the aluminum film is broken and needs to be replaced, the old adhesive residue will increase the difficulty of cleaning and re-pasting. It is a time-consuming and laborious process to completely remove the old adhesive in order to re-paste the new aluminum film. In order to facilitate replacement when the aluminum film is broken, the following settings are made. The bottom of the bottom ring 3 is provided with a mounting assembly 4 for firmly sleeving the barrel-shaped aluminum film 2 inside the paper barrel 1. The mounting assembly 4 includes a connecting plate 41 fixed on the bottom of the bottom ring 3. The side of the connecting plate 41 is provided with a triangular groove 42. The side of the trapezoidal block 45 is fixedly connected with a pull ring 49. The side of the trapezoidal block 45 away from the pull ring 49 is matched with the inside of the triangular groove 42. The top of the paper barrel 1 is provided with a connecting groove 43 matched with the connecting plate 41. The side of the paper barrel 1 is provided with a rectangular groove 44 communicated with the connecting groove 43. The trapezoidal block 45 is slidably sleeved in the rectangular groove 44. The side of the trapezoidal block 45 is coated with a Teflon coating 6 to reduce the friction of the contact surface between the connecting plate 41 and the trapezoidal block 45 when the connecting plate 41 moves downward. Although Teflon itself is relatively soft, its chemical properties and structure make it exhibit excellent wear resistance when it comes into contact with other materials, and it can maintain stable performance under high load and repeated movement conditions, with very low friction coefficient. This can effectively reduce the friction and wear when the connecting plate 41 moves downward and comes into contact with the trapezoidal block 45, thereby prolonging the service life of the connecting plate 41 and the trapezoidal block 45. The inner top wall of the rectangular groove 44 is provided with a sliding groove 47. The sliding groove 47 is slidably connected with a sliding block 46 fixedly connected with the top of the trapezoidal block 45. One side of the sliding block 46 is fixedly connected with an elastic sheet 48 fixedly connected with the inner side wall of the sliding groove 47. When the barrel-shaped aluminum film 2 is broken, pull the pull ring 49 to make the trapezoidal block 45 away from the triangular groove 42 and put into the rectangular groove 44. Lift the bottom ring 3 to move the connecting plate 41 out of the connecting groove 43, and then separate the top ring 5 and the bottom ring 3 to disassemble and replace the old barrel-shaped aluminum film 2. After replacing the new barrel-shaped aluminum film 2, first combine the top ring 5 and the bottom ring 3, then cover the bottom ring 3 on the top of the paper barrel 1 to make the connecting plate 41 inserted into the connecting groove 43. During the process of inserting the connecting plate 41 into the connecting groove 43, the trapezoidal block 45 gradually retracts into the rectangular groove 44 under the downward force of the connecting plate 41. When the connecting plate 41 is completely inserted into the connecting groove 43, the trapezoidal block 45 is reset and clamped with the triangular groove 42 through the elastic sheet 48, realizing the disassembly and replacement of the barrel-shaped aluminum film 2. This makes it easier to disassemble the old barrel-shaped aluminum film 2 and install the new aluminum film 2, which can greatly shorten the replacement time compared with the existing bonding method.

[0027] The above is only a preferred embodiment of the present application and does not limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
