Description

Technical Field

[0001] The invention relates to the technical field of artificial stones, in particular to a stone hot extrusion transfer production line. Background Art

[0002] Artificial granite is a kind of stone made by crushing the original stone and adding other raw materials. The original stone powder is made into various required shapes through thermal processing. It is often used in the construction and decoration industry. The existing stone production usually uses cutting equipment to cut the whole stone after forming. The process is complicated, and the structure of the existing forming machine is complicated, and the production efficiency is low.

[0003] To this end, the prior art (announcement number: CN213108318U, announcement date: 2021.05.04) discloses a stone hot extrusion molding machine, which puts the raw materials into a storage tank, and the extrusion mechanism extrude the raw materials in the storage tank and squeezes them into the molding cavity, and finally processes and shapes them to achieve rapid production of artificial granite.

[0004] The artificial granite produced in the above scheme is a long stone structure, which needs to be cut according to the actual length requirements, so that it can be suitable for the corner decoration of various walls. This kind of product is generally used for the corner protection of the wall, and at the same time cooperates with the tile covering to achieve the effect of interior decoration. In order to ensure the beauty of the long stone, it is necessary to decorate the surface of the long stone. The existing decoration technology usually adopts manual decals or spraying, which is inefficient and it is difficult to ensure the consistency and quality of the pattern.

[0005] With the development of technology, thermal transfer technology has been introduced into the field of stone processing. However, the existing thermal transfer equipment and stone hot extrusion molding machines are two sets of equipment, which not only take up a large space, but also require the long stone strips to be reheated before thermal transfer to ensure that the long stone strips can be reshaped and have sufficient temperature for thermal transfer. Due to the high power consumption and long time required for reheating, the manufacturing cost of the product is high and the manufacturing efficiency is low.

[0006] In addition, the long stone produced by the above scheme (CN213108318U) is shaped by extrusion into a mold and then heated and cured. Therefore, the heat of the product when it is discharged is very high. The heating and curing temperature is between 150 and 200 degrees Celsius, and the temperature when it is discharged is also above 100 degrees Celsius.

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1-8 As shown, a stone hot extrusion transfer production line of the present invention comprises a frame 1, an upper conveyor line 2 and a lower conveyor line 3 are installed on the frame 1, the upper conveyor line 2 and the lower conveyor line 3 correspond to each other up and down, and a long stone 4 is driven and connected between the upper conveyor line 2 and the lower conveyor line 3; The frame 1 is fixedly provided with a first height adjustment mechanism 5, which drives the upper conveyor line 2 and the lower conveyor line 3 to move closer to or away from each other; The frame 1 is fixedly provided with a second height adjustment mechanism 6, which is driven by a pressing wheel 7, and is arranged on the right side of the upper conveyor line 2 and the lower conveyor line 3. A thermal transfer coil 8 is installed on the frame 1, and the thermal transfer coil 8 is attached to the long stone 4 through the pressing wheel 7 after being pulled out. The principle is: directly install it at the discharge port 25 of the prior art (CN213108318U) for use. Since the long stone 4 has a high temperature when it is just formed and discharged, the long stone 4 is transported between the upper conveyor line 2 and the lower conveyor line 3 for pressure maintenance and transportation. At the same time, the thermal transfer coil 8 is pulled out, and the thermal transfer coil 8 is pressed on the long stone 4 through the pressure wheel 7, so that the long stone 4 is input into the upper conveyor line 2 and the lower conveyor line 3 together. The technical effect is achieved. The conveyor lines 3 all have a certain conveying length, and the long stone strips 4 have a certain residual temperature during the conveying process, so the thermal transfer coil 8 can be directly thermally transferred to the surface of the long stone strips 4 without secondary heating and shaping. In addition, the long stone strips 4 can be straighter after being conveyed by the upper conveyor line 2 and the lower conveyor line 3, ensuring their production quality. Since this solution directly performs pressure maintenance and thermal transfer when the long stone strips 4 are formed and discharged, the pattern can be quickly printed on the surface of the long stone strips 4, with high production efficiency and guaranteed consistency and quality of the transferred pattern.

[0034] Furthermore: two second height adjustment mechanisms 6 are provided, the upper conveyor line 2 and the lower conveyor line 3 are provided between the two second height adjustment mechanisms 6, and the thermal transfer roll 8 is stably transferred onto the surface of the long stone 4 through the pressure wheels 7 of the two height adjustment mechanisms 6.

Since the present solution is to transfer the long stone 4 immediately after it is formed and discharged, there is no need for secondary heating, and the transfer can be achieved only by heat preservation and pressure maintenance, which can effectively reduce the energy consumption of the equipment and improve the production efficiency.

[0036] Furthermore: a waste winding roller 10 is installed on the frame 1, and the waste winding roller 10 is arranged on the left side of the upper conveyor line 2 and the lower conveyor line 3.

[0047] Furthermore, a concave groove 23 corresponding to the upper surface of the long stone 4 is formed in the middle of the pressing wheel 7, which can make the thermal transfer coil 8 fit the surface of the long stone 4 more closely, thereby ensuring the transfer effect.
