Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a glass wool board plastic sealing device. Background Art

[0002] Glass wool board is a commonly used building insulation material. Packaging design is a crucial part of glass wool board production. Packaging design needs to consider the characteristics and uses of the product, and select appropriate packaging materials and packaging methods to ensure that the product is not damaged during transportation and storage.

[0003] Glass wool boards are often covered with plastic film during the packaging process, which is mainly to protect the glass wool boards themselves and provide additional functions. First of all, the plastic film can play a role in waterproofing and moisture-proofing. As a thermal insulation material, once the glass wool board is invaded by water or moisture, its thermal insulation performance will be greatly reduced, or even lead to failure. Therefore, covering it with a plastic film can effectively protect it from moisture. Secondly, the plastic film can also play a role in dust and cleaning. The glass wool board may be contaminated by dust, dirt, etc. during use, and covering it with a plastic film can effectively keep its surface clean and ensure that its thermal insulation performance is not affected. In addition, the plastic film can also prevent the glass wool boards from rubbing against each other, causing damage and generating a large amount of debris.

[0004] CN219884237U A rock wool board plastic sealing device, including two groups of conveying mechanisms, a film coating component and a heat shrink film machine, there is a gap between the two groups of conveying mechanisms, the film coating component is arranged in the gap between the two groups of conveying mechanisms, and the heat shrink film machine is arranged at the output end of the conveying mechanism; the film coating component includes a mounting frame, on which two rotating shafts are rotatably arranged, the two rotating shafts are respectively on both sides of the supporting surface of the conveying mechanism, a mounting tube is arranged outside the rotating shaft, a torsion spring is arranged between the rotating shaft and the mounting tube, and a plastic sealing film is wound on the mounting tube. The rock wool board plastic sealing device, under the action of the torsion spring, stores elastic potential energy when pulling the plastic sealing film, and when the rock wool board stops moving, tightens the plastic sealing film to keep the plastic sealing film in a tight state, so as to ensure that the output of the plastic sealing film meets the film coating requirements of the rock wool board.

[0005] The rotating shafts of the above-mentioned plastic sealing equipment are arranged side by side up and down. In actual application, the plastic sealing film may adhere to each other and overlap, and may even accidentally touch the hot pressing mechanism, causing the plastic sealing film to melt and fail to wrap normally.

[0006] Based on this, the technical problem solved in this case is: how to further optimize the plastic sealing quality of glass wool board. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figures 1 to 4 A glass wool board plastic sealing device comprises a support 1, a film cutting mechanism 2 and a conveying mechanism 3. The conveying mechanism 3 is used to convey the glass wool board to pass through the support 1 and the film cutting mechanism 2 in sequence. The support 1 is provided with a first roller 4 and a second roller 5 which are arranged front and back along the feeding direction of the conveying mechanism 3; the first roller 4 is arranged below the conveying mechanism 3, and the second roller 5 is arranged above the conveying mechanism 3; the first roller 4 and the second roller 5 are both used to place a plastic sealing film roll, and the free end of the plastic sealing film of the first roller 4 is connected to the free end of the plastic sealing film of the second roller 5 to form a continuous plastic sealing film; the film cutting mechanism 2 is used to fuse the continuous plastic sealing film.

[0019] The first roller 4 and the second roller 5 of this embodiment are arranged front and back and are respectively located below and above the conveying mechanism 3, and then the free ends of the two are connected to form a continuous plastic film. The continuous plastic film is L-shaped in a natural state. When the glass wool board is pulled, the plastic film can quickly wrap the surface of the glass wool board, thereby improving the plastic sealing quality of the glass wool board and reducing the consumption of the plastic film.

[0020] Specifically, the film cutting mechanism 2 includes a first lifting unit 21 suspended above the conveying mechanism 3, a bottom plate 22 arranged on the bracket 1, and a hot pressing strip 23 arranged on the movable end of the first lifting unit 21; the first lifting unit 21 is used to drive the hot pressing strip 23 to contact the bottom plate 22.

[0021] In this embodiment, the structure of the film cutting mechanism 2 can refer to another patent of our company (Announcement No.: CN206797905U), but the driving mode of the utility model is replaced by the vertical movement of the first lifting unit 21 controlled by PLC. It should be noted that the first lifting unit 21 of this embodiment is a first cylinder, which has a higher degree of automation.

[0022] More specifically, the conveying mechanism 3 includes a first conveyor belt 31 and a second conveyor belt 32 for conveying in the same direction; the first conveyor belt 31 and the second conveyor belt 32 are respectively arranged on both sides of the film cutting mechanism 2 .

[0023] In actual application, the bottom plate 22 of the film cutting mechanism 2 should be placed between the first conveyor belt 31 and the second conveyor belt 32. When the glass wool board completely passes through the second roller 5, the film cutting mechanism 2 can cut and seal the continuous plastic film.

[0024] As a preferred embodiment of this embodiment, it also includes a film pressing mechanism 6 arranged on the bracket 1 and used to make the continuous plastic sealing film close to the upper end surface of the glass wool board. The film cutting mechanism 2 and the film pressing mechanism 6 are arranged front and back along the feeding direction of the conveying mechanism 3.

[0025] As a further preferred embodiment of the present invention, the film pressing mechanism 6 comprises a second lifting unit 61 suspended above the conveying mechanism 3, and a film pressing frame 62 arranged on the movable end of the second lifting unit 61; the film pressing frame 62 comprises a vertical plate 621 for blocking the glass wool board from advancing along the feeding direction of the conveying mechanism 3, and a horizontal plate 622 for making the continuous plastic film close to the upper end surface of the glass wool board. In the present embodiment, the second lifting unit 61 is a second cylinder.

[0026] Under the above-mentioned preference, the film pressing mechanism 6 plays two roles, namely, blocking the glass wool board from moving forward and further making the continuous plastic sealing film close to the upper end surface of the glass wool board. It should be noted that in order to better achieve the above-mentioned effects, the actual working process should be as follows: when the glass wool board has completely passed the second rotating roller 5, the glass wool board is blocked by the vertical plate 621, and the first lifting unit 21 of the film cutting mechanism 2 drives the hot pressing strip 23 to press down, so that the upward-inclined continuous plastic sealing film gradually approaches the glass wool board. In this process, the second lifting unit 61 of the film pressing mechanism 6 drives the horizontal plate 622 to press down, so that the continuous plastic sealing film is close to the upper end surface of the glass wool board, and finally the film cutting mechanism 2 completes the cutting and sealing.

[0027] As a preferred embodiment of the present invention, a heat sealing mechanism 7 is further included, which is arranged on the support 1 and is used to shrink the plastic sealing film. The heat sealing mechanism 7 and the film pressing mechanism 6 are arranged front and back along the feeding direction of the conveying mechanism 3. In the present embodiment, the structure of the heat sealing mechanism 7 is a heat shrink film machine commonly used in the art, so in the present embodiment, no additional description is given.

[0028] As a preferred embodiment of this invention, a first guide rod 101 is further provided on the bracket 1; the first guide rod 101 is arranged below the conveying mechanism 3; the free end of the plastic film on the first roller 4 is connected to the free end of the plastic film on the second roller 5 through the first guide rod 101.

[0029] As a preferred embodiment of the present invention, a second guide rod 102 is further provided on the bracket 1; the second guide rod 102 is arranged above the conveying mechanism 3; the free end of the plastic film on the second roller 5 is connected to the free end of the plastic film of the second roller 5 through the second guide rod 102.

[0030] In practical applications, at least two first guide rods 101 are used in combination, and the same is true for the second guide rods 102 .

[0031] Under the above-mentioned preference, the plastic film on the first roller 4 and the second roller 5 is first stretched by the first guide rod 101 and the second guide rod 102 respectively, which can not only support the plastic film so that it will not fall, but also pre-stretch the plastic film, thereby preventing the plastic film from being deformed due to excessive traction.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
