Description

Technical Field

[0001] This utility model relates to the field of foam cover plates, and in particular to a foam cover plate that prevents water seepage and moisture. Background Technology

[0002] In the production process of foam board, the raw materials are first heated to high temperature by steam in an intermittent pre-expansion machine to form foam particles. After the foam particles are shaped, they are sent to the curing zone. After a series of curing processes, the foam particles are shaped and then transported by a foam molding machine to the mold for high-temperature heating and shaping to obtain a foam board of a certain shape.

[0003] Foam boards can be used for packaging finished spun yarn products. For example, foam baseboards, foam partitions, and foam covers can be used to package yarn cakes, with the foam cover placed on top of stacked yarn cakes. To achieve proper fit between the foam cover and the paper tubes within the yarn cake, holes can be made in the foam cover. However, these holes allow external moisture and humidity to easily penetrate, causing the paper tubes in contact with it to become damp. Damp paper tubes have reduced structural strength, making the yarn cakes unstable during transportation and prone to collapse, leading to accidents, property damage, and issues such as poor product quality and incomplete yarn removal. Utility Model Content

[0004] The purpose of this invention is to provide a foam cover that prevents water seepage and moisture, improves waterproof and moisture-proof performance, and ensures the packaging stability of silk cakes.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A foam cover plate that prevents water seepage and moisture absorption includes: a foam substrate and positioning grooves arrayed on the bottom surface of the foam substrate. The foam substrate is a square plate or a circular plate. A paper tube is disposed in the filament cake. The positioning groove is a circular groove. The diameter of the positioning groove corresponds to the outer diameter of the paper tube. The positioning groove is a blind groove to prevent water seepage and moisture absorption of the foam substrate in the thickness direction.

[0007] The bottom of the positioning groove is chamfered.

[0008] The foam substrate has a first ventilation channel recessed on its top surface, and both ends of the first ventilation channel extend to the edge of the foam substrate.

[0009] The foam substrate has a second ventilation guide groove that intersects with the first ventilation guide groove on its top surface.

[0010] The top surface of the foam substrate is provided with a waterproof coating.

[0011] The waterproof coating is made of a layer of UV adhesive.

[0012] A cardboard cover is provided on top of the foam substrate.

[0013] The beneficial effects of this utility model are as follows: A foam cover that prevents water seepage and moisture absorption utilizes the positioning groove on the bottom surface of the foam substrate to connect with the paper tube on the yarn cake, thus stabilizing it inside the foam cover. This reduces the shaking of the yarn cake, avoids quality problems caused by fuzz due to the shaking of the yarn cake, and ensures the barrier against moisture, improving waterproof and moisture-proof performance. It also prevents water seepage and wet yarn from occurring during outdoor storage and transportation due to climate changes, ensuring the structural strength and stability of the paper tube, making it safer to use.

[0019] The following is combined with Figures 1 to 5 The technical solution of this utility model will be further illustrated through specific embodiments.

[0020] like Figure 1 The foam cover shown is designed to prevent water seepage and moisture absorption. It is used for packaging the silk cakes 3 and includes: a foam substrate 1 and six positioning grooves 11 arrayed on the bottom surface of the foam substrate 1. The foam substrate 1 can be a square or round plate; in this embodiment, it is a square plate, providing protection for the six silk cakes 3. Each silk cake 3 contains a paper tube 4, such as... Figure 4 As shown, the end of the paper tube 4 protrudes beyond the silk cake 3, facilitating connection with the positioning groove 11.

[0021] like Figure 3 As shown, the positioning groove 11 is a circular groove, and the diameter of the positioning groove 11 corresponds to the outer diameter of the paper tube 4, ensuring a tight fit. In this embodiment, the bottom end of the positioning groove 11 is provided with a chamfer 12 to facilitate the entry of the paper tube 4 into the positioning groove 11 during packaging.

[0022] like Figure 1As shown, the positioning groove 11 is a blind groove to maintain the water seepage and moisture absorption effect of the foam substrate 1 in the thickness direction, ensure the barrier against water vapor, improve waterproof and moisture-proof performance, avoid the influence of water vapor above the foam substrate 1 on the end of the paper tube 4, ensure the structural strength and stability of the paper tube 4, and make the stacking and transportation process safer.

[0023] like Figure 2 As shown, a first ventilation guide groove 13 is recessed on the top surface of the foam substrate 1, and the two ends of the first ventilation guide groove 13 extend to the edge of the foam substrate 1. In this embodiment, a second ventilation guide groove 14 intersects the first ventilation guide groove 13 on the top surface of the foam substrate 1. The first ventilation guide groove 13 and the second ventilation guide groove 14 are used to enhance the ventilation and guide effect of the top surface of the foam substrate 1, avoid water accumulation on the top surface of the foam substrate 1, and accelerate the ventilation and drying of the top surface of the foam substrate 1.

[0024] like Figure 5 As shown, in this embodiment, a waterproof coating 2 is provided on the top surface of the foam substrate 1 to enhance its waterproof performance. The waterproof coating 2 is a layer of UV adhesive. The UV adhesive can not only improve the waterproof effect of the top surface of the foam substrate 1, but also improve the structural stability, reduce cracking problems, and help reduce the thickness of the foam substrate 1, thereby reducing the weight and raw material cost of the foam substrate 1.

[0025] like Figure 4 As shown, a cardboard cover 5 is provided above the foam substrate 1. The cardboard cover 5 provides physical protection for the foam substrate 1, facilitates the use of packing ropes, and prevents the packing ropes from contacting the foam substrate 1. In addition, the ventilation effect of the bottom surface of the cardboard cover 5 is enhanced by the first ventilation channel 13 and the second ventilation channel 14, further improving the moisture-proof performance.

[0026] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
