Example 1:
aiming at the leveling method of the automobile interior trim leftover material, the utilization rate of the leftover material and the purity of the recovered material can be improved, and as shown in figure 1, the method is particularly set as follows:
the method adopts the existing hot press as hot pressing equipment, and utilizes the hot press to carry out hot pressing and flattening on the leftover materials, and the hot-pressed leftover materials are preferably in the same specification, and the method comprises the following steps:
step S1, a cushion 2 is laid on the top surface of a base 1 of the hot press, and the cushion 2 is preferably set to be a zero-degree silica gel cushion which is soft in texture and has good deformability. The size of the soft cushion 2 generally needs to be larger than the width of the leftover materials to be hot-pressed, and overlong leftover materials are flattened by adopting a multi-time hot pressing mode;
s2, placing the leftover materials 4 on the soft cushion 2, enabling the PET layer of the leftover materials 4 to face downwards and to be in contact with the soft cushion 2, and enabling the EVA layer of the leftover materials 4 to face upwards to the hot pressing plate 3;
s3, controlling the hot pressing plate 3 to downwards contact the EVA layer of the leftover material 4, then controlling the hot pressing plate 3 to continuously downwards press the PET layer of the leftover material 4 against the soft cushion 2 to improve the flatness of the leftover material 4, and heating the leftover material 4 by the hot pressing plate 3 in the pressing process to soften the EVA layer of the leftover material 4 so that the EVA layer can be leveled;
s4, keeping the hot pressing plate 3 still, and continuously heating the EVA layer of the leftover material 4, wherein the EVA layer of the leftover material 4 is required to be kept not to be melted;
and S5, controlling the hot pressing plate 3 to move upwards and to be separated from the hot-pressed leftover materials 4 after the required hot pressing time is reached.
In the step S3 and the step S4, the heating temperature of the hot pressing plate 3 is generally set to be constant, the temperature value is set to be 110-150 ℃, the total heating time of the EVA layer of the hot pressing plate 3 contacting the leftover material 4 is set to be 85-170S according to the difference of the temperature, and multiple sets of parameters can be obtained. Such as:
the first set of parameters, the heating temperature of the hot press plate 3 was set to 110 ℃ and the total heating time was set to 170s.
The second set of parameters, the heating temperature of the hot press plate 3 was set to 120 ℃ and the total heating time was set to 150s.
The third set of parameters, the heating temperature of the hot press plate 3 was set to 130 ℃ and the total heating time was set to 120s.
The fourth set of parameters, the heating temperature of the hot press plate 3 was set to 140 ℃ and the total heating time was set to 90s.
In the fifth set of parameters, the heating temperature of the hot press plate 3 was set to 150 ℃ and the total heating time was set to 60 seconds.
The fourth set of parameters is preferred because the EVA layer with the leftover material set in the fourth set of parameters is not softened too much even heated to 140 ℃, has short heating time and has high processing efficiency.
And taking down the flattened leftover materials after the five steps, taking the leftover materials needing hot pressing again, and repeating the steps from S2 to S5.
When the method is adopted, the cushion 2 is arranged on the top surface of the base 1 of the common hot press, so that the PET layer of the leftover material 4 is pressed against the cushion 2. Because cushion 2 has certain elasticity and can warp, the position that cushion 2 and leftover bits 4 contacted first can be pressed caving in, the position evagination that does not contact then relatively sunken, so can make cushion 2 better, earlier fully contact with the upper concave part of leftover bits 4, later make 4 unevennesses of leftover bits receive more abundant extrusion and heating everywhere, improve the roughness of leftover bits 4, so that, leftover bits 4 also can obtain better roughness when receiving less extrusion force, can reduce the degree of depth on the EVA layer of impressing on the PET layer, reduce the separation degree of difficulty of leftover bits, improve the purity of separation material. Zero degree silica gel can obtain fine deformation when the pressurized, can fully contact with the PET layer of leftover bits 4, makes leftover bits 4 obtain better roughness.
In order to improve the hot pressing quality of the leftover materials, the pressure of each hot pressing needs to be ensured to be maintained within a certain range, preferably, the aim is achieved by setting the maximum stroke of the hot pressing plate 3, after the step S1 is completed and before the step S2 is carried out, the minimum clearance between the hot pressing plate 3 and the cushion 2 is adjusted, the minimum clearance is the same as the thickness of the leftover materials 4 to be hot pressed, generally between 3 mm and 5mm, and corresponding adjustment is carried out according to the leftover materials with different specifications, for example 4mm. Minimum clearance between hot pressboard 3 and cushion 2 is adjusted according to the thickness of the leftover bits 4 of wanting the hot pressing in advance, makes leftover bits 4 can receive appropriate extrusion pressure degree, does not lead to making the PET layer by the EVA layer of impressing too much when the EVA layer of leftover bits 4 softens to be favorable to the later stage to separate.
Example 2:
the embodiment is further optimized on the basis of the above embodiment, and in order to further better implement the invention, the following method is particularly adopted:
before step S4 in example 1, water is sprayed to the PET layer of the leftover material 4 to cool the PET layer, and the temperature of the sprayed water is lower than the heating temperature of the hot platen 3. The water spray can adopt the shower nozzle to face to the PET layer water spray from side, also can follow 2 spouts on the cushion under the PET layer, for example be provided with a plurality of water courses 5 that link up from top to bottom at cushion 2, water course 5 is connected with the water source, makes the surface of cushion 2 be stained with water or spout water spray or water column through 5 water sprays of water course, drenches the PET layer, realizes the PET layer cooling to leftover bits 4.
When the method is adopted, the water is sprayed to the PET layer of the leftover material 4, so that the connecting belt of the PET layer and the EVA layer can be cooled, one side of the EVA layer connected with the PET layer is not excessively softened, the PET layer can be pressed into the EVA layer less, and later separation is facilitated.
Example 3:
the embodiment is further optimized on the basis of the embodiment, and particularly adopts the following method for better realizing the invention:
can also be less than the leftover bits after the hot pressing through a temperature and colding the cold pressing board to the leftover bits after the hot pressing after step S5 colds pressing, the cold pressing board can be the component of another a set of not heated hot press, and the cold pressing can promote its cooling rate to the leftover bits and improve production efficiency, and the cold pressing board is pressed and also can be prevented its cooling deformation on the leftover bits, if the size of cold pressing board is greater than the size of leftover bits then also can place the leftover bits and stick up the limit when cooling.
In the cold pressing process, the temperature of the cold pressing plate is generally in a room temperature state, and the cold pressing time is 5-15s from the time when the leftover materials are pressed on the silica gel pad. Generally controlling the heating temperature at 140 ℃ and the total heating time at 90s, and controlling the cold pressing time at 10s; the heating temperature is controlled at 110 ℃, the total heating time is controlled at 170s, and the cold pressing time is generally controlled at 5s; when the heating temperature is controlled at 150 ℃ and the total heating time is controlled at 60s, the cold pressing time is generally controlled at 15s.
When the method is adopted, the cold pressing can promote the cooling of the leftover materials, the production efficiency of flattening the leftover materials can be improved, meanwhile, the cold pressing can also prevent the leftover materials from deforming in the cooling process so as to keep the flatness, and meanwhile, the leftover materials are prevented from warping when being cold pressed so that the shape of the leftover materials is unified, and the later-stage large-batch separation is facilitated.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and shall cover the scope of the present invention.
