[0039] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0040] The production equipment of the multi-color waterproof floor mat includes an extruder, an extrusion molding device, a cooling molding device, a water removal and drying device and a glue pressing device which are sequentially arranged along the front and back of the production line.

[0041] like Figure 1 As shown, the extrusion molding device includes a distributed die head connected to the output end of the extruder, a material collecting plate 1 located below the distributed die head, and an extrusion template; the distributed die head is provided with at least two material distribution gaps 2 for distributing materials of different colors. Figure 2 As shown, the material collecting plate 1 is provided with material collecting grooves 3 which are connected with the material distributing gaps 2 in a one-to-one correspondence, and each material collecting groove 3 is independent of each other. A material discharge area 4 is provided on each material collecting groove 3, and a material discharge through hole 5 is provided on the material discharge area 4. The material discharge areas 4 on different material collecting grooves 3 are arranged alternately and non-overlappingly, and the material discharge through holes 5 on different material collecting grooves 3 can be combined into a continuous row; Figure 3 , 4As shown, the extrusion template includes an upper extrusion template 6 and a lower extrusion template 7 arranged up and down, an upper wide hole 8 and an upper narrow hole 9 are alternately arranged on the upper extrusion template 6, and a lower wide hole 10 and a lower narrow hole 11 are alternately arranged on the lower extrusion template 7, the upper wide hole 8 corresponds to the lower wide hole 10 one by one, and the upper narrow hole 9 corresponds to the lower narrow hole 11 one by one. The area of ​​the upper wide hole 8 is 2.5-3.5 times the area of ​​the lower wide hole 10, the area of ​​the upper narrow hole 9 is 1-1.5 times the area of ​​the lower narrow hole 11, and the area of ​​the lower wide hole 10 is 1-1.5 times the area of ​​the lower narrow hole 11. An edge is arranged on one width side of the lower wide hole 10, and the material extruded through the lower wide hole 10 is a corrugated line. The effect of the edge causes the surface of the corrugated line to form edges, thereby increasing the anti-slip effect, and the material extruded through the lower narrow hole is a straight strip line.

[0042] The number of the cloth gaps 2 is the same as the number of extruders, and the number of extruders is the same as the number of material colors. Materials of the same color are extruded into the cloth gaps 2 of the distributed die head through the same extruder.

[0043] In this embodiment, there are two extruders, two material distribution gaps 2 and two material collection troughs 3. In order to allow the material to smoothly enter the material collection trough 3 from the material distribution gap 2, a material guide plate 12 is further provided between the distributed die head and the material collection plate 1, and a material guide channel 13 connecting the material distribution gap 2 and the material collection trough 3 is provided on the material guide plate 12.

[0044] In the embodiment, each material distribution gap 2 is provided with at least one material baffle plate 14 arranged along the length direction of the material distribution gap 2. The material baffle plate 14 can slow down the material flow speed and improve the material distribution effect.

[0045] like Figure 1 , 5 As shown, the distributed die head includes a die head housing 15, a fixed block 16 located inside the die head housing 15, and a deformable block 17 located on both sides of the fixed block 16; a material distribution gap 2 arranged along the long axis direction of the distributed die head is formed between the fixed block 16 and the two deformable blocks 17; there is a material flow space 18 above each material distribution gap 2 and between the die head housing 15, the material flow space 18 is high in the middle and low at both ends, a material feed port 19 is arranged in the middle of the distributed die head, the width of the material distribution gap 2 in the middle is 2mm, and the width of the material distribution gap 2 at both ends is 3mm, the arrangement of the material flow space 18 and the width of the material distribution gap 2 can facilitate uniform material distribution and avoid material discharge through the middle of the material distribution gap 2. The deformable block 17 is deformed by an externally arranged tightening bolt 20 to change the width of the material distribution gap 2 between the deformable block 17 and the fixed block 16 to meet production needs.

[0046] The cooling and forming device is a water tank filled with cooling water. After the material is extruded and formed by the extrusion forming device, it is transported to the cooling water for cooling. The dewatering and drying device includes a rotating striking rod and a hot air drying box. The semi-finished floor mat after cooling and forming is struck and dewatered by the striking rod, and then dried by the hot air drying box. The gluing device includes a glue tank, a rotatable glue coating roller located in the glue tank, and a pressure roller located above the glue coating roller. The semi-finished floor mat passes between the pressure roller and the glue coating roller, and is coated with glue by the glue coating roller. The cooling and forming device, the dewatering and drying device, and the gluing device all adopt existing conventional structures, which will not be described in detail here.

The position of the feeding area 4 on the material collection trough 3 can be adjusted according to different products to meet the color distribution requirements of the products.

[0050] (3) The semi-finished floor mat after extrusion molding is sequentially conveyed to the cooling molding device, the water removal and drying device and the gluing device for cooling molding, water removal and drying and gluing treatment. The conveying speed of the semi-finished floor mat is 2m / min. The semi-finished floor mat after gluing treatment is then dried in an oven, left to cool after drying, and then trimmed to obtain the finished product, and finally the finished product is rolled up.

[0051] The materials in Example 1 are black and green, respectively. Figure 6 As shown, a mat with black and green areas alternately arranged is formed. The width of the black and green areas is 4-6 cm respectively.

[0052] In Example 2, a method for producing a waterproof floor mat using the above-mentioned production equipment comprises the following steps:

[0054] (2) After being melted and extruded, materials of different colors enter corresponding feeding gaps 2 respectively, and then enter corresponding material collection troughs 3 after being fed through feeding gaps 2. Each material collection trough 3 corresponds to a material of one color, and the materials are fed through feeding holes 5 on each material collection trough 3 and extruded through upper extrusion template 6 and lower extrusion template 7 to form the materials. The position of the feeding area 4 on the material collection trough 3 can be adjusted according to different products to meet the color distribution requirements of the products.

[0055] (3) The semi-finished floor mat after extrusion molding is sequentially conveyed to the cooling molding device, the water removal and drying device and the gluing device for cooling molding, water removal and drying and gluing treatment. The conveying speed of the semi-finished floor mat is 2m / min. The semi-finished floor mat after gluing treatment is then dried in an oven, left to cool after drying, and then trimmed to obtain the finished product, and finally the finished product is rolled up.

[0056] The materials in Example 2 are black and yellow respectively. Figure 7 As shown, a ground mat with black and yellow areas alternately arranged is formed. The width of each black and yellow area is 0.5-2cm respectively.

[0057] The waterproof floor mats produced in Example 1 and Example 2 and ordinary waterproof floor mats on the market were simultaneously applied to a public toilet somewhere, and it was found that the service life of the waterproof floor mats in Example 1 and Example 2 was 2-3 years, while the service life of ordinary waterproof floor mats was at most 1 year.
