Description
Technical Field
[0001] The utility model relates to the technical field of household mat production, in particular to a magic color PVC mat and its production equipment. Background Technique
[0002] Household mats are generally made of PVC foam materials and can be used in scenarios such as floor anti-slip, children's play, yoga, and picnics, and are widely used in household life. Most of the current PVC foam household mats are single-color foaming, and the color appearance is relatively single. If you want to produce multi-color mats, you need to add a printing process, which increases production costs, and the printing process usually brings other problems, such as environmental protection, color fading, and odor. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a magic color PVC mat and its production equipment. The PVC foam material constituting the mat body is formed by random color collision of two or more color slurries, bringing a diverse color effect.
[0004] To achieve the above purpose, the utility model provides the following technical scheme: a magic color PVC mat, including a mesh base and a mat body. The mesh base is a grid-shaped chemical fiber blank fabric, and the mat body is a PVC foam material. The mat body includes an upper mat body and a lower mat body. The upper mat body and the lower mat body are distributed above and below the mesh base. The upper mat body and the lower mat body penetrate through the meshes of the mesh base and are connected to form the entire mat body. The mat body is formed by the interval of two or more PVC foams. The boundary line between the two or more PVC foams is streamlined and is randomly formed.
[0005] Under a production condition, the magic color PVC mat of the utility model is rectangular and is formed by the interval of two PVC foams, namely PVC foam one and PVC foam two. The PVC foam one and the PVC foam two are strip-shaped on the surface of the magic color PVC mat and extend in the direction parallel to one side of the magic color PVC mat, and are arranged at intervals in the direction perpendicular to this side.
[0006] Under the second production condition, the magic color PVC mat of the utility model is rectangular and is formed by the interval of two PVC foams, namely PVC foam one and PVC foam two. The PVC foam one and the PVC foam two are annular or semi-annular, and the PVC foam one and the PVC foam two show a form of surrounding each other in turn on the surface of the magic color PVC mat.
[0007] The PVC foam spacer patterns brought about by the first production condition and the PVC foam spacer patterns brought about by the second production condition may be presented simultaneously on the iridescent PVC mat. That is, on the surface of the iridescent PVC mat, at some positions, the first PVC foam and the second PVC foam are arranged in a long-strip shape at intervals in turn, and at some positions, the first PVC foam and the second PVC foam surround each other in a circular or semi-circular shape in turn.
[0008] When the mat body is formed by three kinds of PVC foams, including the first PVC foam, the second PVC foam, and the third PVC foam, it brings more random change patterns. On the surface of the iridescent PVC mat, at some positions, the first PVC foam and the second PVC foam are arranged in a long-strip shape at intervals in turn, at some positions, the first PVC foam and the second PVC foam surround each other in a circular or semi-circular shape in turn, at some positions, the first PVC foam and the third PVC foam are arranged in a long-strip shape at intervals in turn, at some positions, the first PVC foam and the third PVC foam surround each other in a circular or semi-circular shape in turn, at some positions, the second PVC foam and the second PVC foam are arranged in a long-strip shape at intervals in turn, and at some positions, the second PVC foam and the second PVC foam surround each other in a circular or semi-circular shape in turn.
[0009] Furthermore, anti-slip protrusions are provided on the surfaces of the upper mat body and the lower mat body for anti-slip.
[0010] There are various shapes of the anti-slip protrusions, including gravel-like, velvet-like, etc., and the shape can be designed according to actual needs. The anti-slip protrusions are formed in one step by hot pressing. Only by adjusting the mold can different shapes be formed.
[0011] Furthermore, the iridescent PVC mat is provided with a plurality of folding lines in the horizontal and vertical directions. The folding lines are lines with a thickness lower than that of the mat body and in a trapezoidal shape. The iridescent PVC mat product is pressed with folding lines by a high-frequency device and folded along the folding lines, which is convenient for carrying; the product without pressed folding lines is stored or carried in a rolled-up manner.
[0012] Furthermore, the iridescent PVC mat can also be cut into other shapes, such as circular, to suit the usage scenarios of circular mats.
[0013] The key feature of the present utility model's colorful PVC mat lies in that two or more PVC foams are distributed at intervals, and the dividing line is streamline and random, which is made by a special equipment. The production equipment for manufacturing the colorful PVC mat includes a coating roller, above which there is a slurry tank. The mesh base passes through the middle of the coating roller and the slurry tank. Above the slurry tank, there is a main slurry tank, and the main slurry tank is provided with a discharge port leading to the slurry tank. On both sides above the slurry tank, there is one or more secondary slurry tanks, and the secondary slurry tanks are provided with feeding pipes leading to the slurry tank. The position of the feeding pipes relative to the slurry tank can move parallelly.
[0014] Using the above equipment, place a slurry of one color in the main slurry tank and slurries of other different colors in one or more secondary slurry tanks. During production, the slurry in the main slurry tank and the slurries in the secondary slurry tanks are mixed in the slurry tank and fed to the mesh base. During the process, the feeding pipes of the secondary slurry tanks move parallelly, and the two or more color slurries are mixed during the collision, that is, "color collision", forming an interval distribution of two or more PVC slurries, with a streamline dividing line between them and a random form of the dividing line. Driven by the rotation of the coating roller, the mesh base brings the slurry into the foaming furnace to be formed, obtaining the colorful PVC mat of the present utility model.
