Description

[Technical Field]

[0001] The present invention relates to the field of mats, and more particularly to multi-layer pressed edge mats. [Background technology]

[0002] The main use of mats is to increase comfort and protect items; they can be placed over equipment and items to provide additional support and comfort; mats made from bamboo strips or grass can be used especially in summer; mats can also be used for outdoor activities; for example, moisture-proof mats used when camping can provide protection from bumps, keep warm, and protect from moisture.

[0003] The existing multi-layer mat production process typically involves first cutting the raw material, and then having workers wrap and bend the edges. These are two separate processes, and it is quite difficult to keep the stitches straight during sewing. In particular, when multiple workers are working at the same time, the skill levels of each worker may vary, making it difficult to maintain consistent product quality. In addition, the fabric used for wrapping the edges must also be specially ordered, which increases the complexity of the production process.

[0004] Therefore, the existing production process for multi-layer mats usually involves first cutting the raw material, and then having workers wrap and bend the edges. These are two independent processes, and it is quite difficult to keep the stitches straight during sewing. In particular, when multiple workers are working at the same time, the skills of the workers may differ. To address this issue, a multi-layer pressed-edge mat can be designed, which integrates a filling medium pad and upper and lower protective layers and uses ultrasonic, high frequency, or hot pressing technology to press the edges, thereby improving protection, durability, and aesthetics while also simplifying the production process. Summary of the Invention [Problem to be solved by the invention]

[0005] The existing multi-layer mat production process typically involves first cutting the raw material, followed by the steps of wrapping and bending the edges. These are two independent processes, and it is quite difficult to keep the stitches straight during sewing. This is particularly true when multiple workers are working at the same time, and the skill levels of each worker may differ. This problem is addressed by the present invention. [Means for solving the problem]

[0006] The technical solution of the present invention is as follows: a multi-layered pressed edge treatment mat, comprising a filling medium pad, a lower protective mechanism, an upper protective medium, and edges that are directly pressed by ultrasonic waves, high frequency waves, or hot pressing, wherein the upper protective mechanism is disposed above the filling medium pad, and the lower protective mechanism is disposed below the filling medium pad, and edges are pressed and connected at the four edges between the lower protective mechanism and the upper protective medium for directly pressing the lower protective mechanism and the upper protective medium by ultrasonic waves, high frequency waves, or hot pressing.

[0007] Preferably, the filling medium pad is the core layer, which is responsible for the product's main functional properties such as cushioning and heat retention. An upper protective medium is placed above the filling medium pad, and a lower protective mechanism is provided below it. The role of this two-layer protective structure is to protect the filling medium in the middle from the influence of the external environment. The four edges between the upper protective medium and the lower protective mechanism are directly crimped and connected using ultrasonic, high frequency, or hot pressing techniques. These techniques use ultrasonic, high frequency, or direct hot pressing to melt or soften the contact surfaces of the materials of each layer, so that they are fused together under pressure to form a strong sealed edge, which is then crimped. A cutter is then used to remove excess material, which can further ensure the neatness and aesthetics of the edges and give the final product a unified finish.

[0008] In a preferred embodiment, the bottom protection mechanism includes a lower cover pad that fits tightly against the bottom of the fill media pad.

[0009] In a preferred embodiment, the upper protective medium includes a top cover pad that fits tightly against the surface of the fill medium pad.

[0010] In a preferred embodiment, the edges of the filling medium pad, the upper cover pad and the lower cover pad are similarly provided with sides that are directly compressed by ultrasonic waves, high frequency waves or hot pressing.

[0011] In a preferred embodiment, the upper cover pad, the lower cover pad and the filling medium pad are set to the same size. [Effects of the Invention]

[0012] The beneficial effects of the present invention are as follows: By providing an upper protective layer above the filling medium pad and a lower protective mechanism below it, comprehensive protection is provided for the filling medium in the middle, protecting it from external environmental influences or damage; by using ultrasonic, high frequency, or hot pressing techniques to tightly and integrally press the upper and lower protective layers and the filling medium pad, the strength and durability of the entire structure is ensured; after undergoing the above-mentioned technical processing, the edges are neater and smoother, which not only improves the aesthetic appearance of the product but also reduces the safety hazards that may be caused by rough edges, such as injury to users; and the crimping and edge processing processes can be completed in one go without the need for additional sewing or gluing steps, which greatly simplifies the production process, improves production efficiency, and helps reduce manufacturing costs.

[0014] The present invention will be further described below with reference to the drawings and examples.

[0015] 1 to 4, the present invention provides the following embodiment: A multi-layered pressed edge treatment mat, comprising a filling medium pad 1, a lower protective mechanism 2, an upper protective mechanism 3, and a side 4 that is directly pressed by ultrasonic waves, high frequency waves, or hot pressing, in which the upper protective mechanism 3 is disposed above the filling medium pad 1, and the lower protective mechanism 2 is disposed below the filling medium pad 1, and the side 4 is pressed and connected to the four edge portions between the lower protective mechanism 2 and the upper protective mechanism 3 for directly pressing the lower protective mechanism 2 and the upper protective mechanism 3 together by ultrasonic waves, high frequency waves, or hot pressing.

[0016] 1 and 2, in this embodiment, the lower protective mechanism 2 includes a lower cover pad 201 that fits tightly to the bottom of the filling medium pad 1. This design effectively enhances the structural stability and durability of the product and better protects the filling medium from damage caused by the external environment. This method of fitting helps to maintain the shape of the product, extend its service life, and facilitates operation and processing during production, thereby improving production efficiency and product quality. The upper protective mechanism 3 includes an upper cover pad 301 that fits tightly to the surface of the filling medium pad 1, improving the overall protective performance of the product and effectively protecting the filling medium from the effects of external factors.

[0017] 2 and 3, in this embodiment, the edges of the filling medium pad 1, the upper cover pad 301, and the lower cover pad 201 are similarly provided with edges 4 that are directly crimped by ultrasonic waves, high frequency waves, or hot pressing. This design ensures close contact between the three layers of material, greatly improving the durability and sealing of the entire product and effectively preventing delamination or edge splitting. The edges treated in this manner are neater and smoother, which not only looks better, but is also safer and eliminates the risk of injury from loose threads or rough edges. The upper cover pad 301, the lower cover pad 201, and the filling medium pad 1 are set to the same size. This design ensures that the materials of each layer are perfectly aligned, avoiding assembly problems caused by dimensional inconsistencies, such as misalignment or uneven edges. The same size design makes the crimping process more uniform and effective, and improves the structural stability of the finished product.

[0018] To carry out the work, first prepare the necessary filling medium pad 1, upper cover pad 301, and lower cover pad 201, ensure that the dimensions of these three layers of material are consistent and suitable for subsequent processing, use an appropriate jig or positioning system to fix the three layers of material together to prevent them from shifting during processing, and select one of the following methods to crimp the edges according to the material properties and production requirements: hot pressing, ultrasonic, or high frequency, which can effectively seal the upper and lower protective media and the filling medium pad 1. Use specially designed equipment to crimp and remove excess edge material with an integrated cutter. This process requires precise control to ensure neat edges and no excess material remains.

[0019] Through the above steps, by crimping and using a cutter to remove excess waste material, the edges of the product are neatly finished, improving the overall appearance quality. Completing the two steps of crimping and cutting at once reduces the time required for each cutting process, helping to improve the efficiency of the entire production line. Precise cutting minimizes material waste due to irregular edges and reduces production costs. Optimizing the edge treatment method further improves the strength and sealing performance of the edge treatment part, making the product more durable. Previous multi-layer mats were all cut and then manually hemmed or folded. This involves two processes, making it very difficult to sew straight. Furthermore, when multiple people are working, the sewing skills vary, making it difficult to control, and the hemming cloth had to be ordered separately. This problem has been solved.
