Example 3
A method of producing a sheet material comprising the steps of:
(1) Feeding, selecting materials according to the requirements of the plates, and in the embodiment, the materials are biological straws. Feeding crushed material from a hopper 3;

(3) And the materials are quickly formed into a molten state in a hot melting device 5 at high temperature and high pressure and directly enter an extrusion die 6 for extrusion molding according to the flowing force. The temperature of the hot melt is generally 100-200 ℃, preferably 140 ℃ in this embodiment, and the pressure is preferably 12MPa, which enables the material to be melted rapidly.

The plate enters the plate channel, and the plate runs on the production line by the rotation traction of the upper layer roller and the lower layer roller.
(7) Cutting to the required sheet size by means of the cutting device 9.
The plate produced by the plate extrusion device is integrally formed with the vertical keels or the grooves, the vertical keels or the grooves penetrate through the whole plate, and the vertical keels or the grooves have certain tensile force on the plate after being installed, so that the problem of long-time bulge of the plate is avoided, and the stability of the plate is improved. Meanwhile, the vertical keels or the grooves on the plates are matched and clamped with the transverse keels, so that the plates are more convenient and quicker to install. When the plate is replaced, the plate is directly taken down at the corresponding position, the plate is not required to be detached from the head for replacement, and the maintenance and the replacement are fast and convenient.
Example 4
A method of producing a sheet material comprising the steps of:
(1) Feeding, and selecting materials according to the requirements of the plates, wherein the materials are plastics in the embodiment. Feeding crushed material from a hopper 3;
(2) The materials in the hopper 3 directly enter the screw conveyor 4 after falling, and enter the hot melting device 5 through the pushing of the screw conveyor 4;
(3) And the materials are quickly formed into a molten state in a hot melting device 5 at high temperature and high pressure and directly enter an extrusion die 6 for extrusion molding according to the flowing force. The temperature of the hot melt is generally 100-200 ℃, preferably 200 ℃ in this embodiment, and the pressure is preferably 14MPa, which enables the material to be melted rapidly.
(4) Extruding and molding by using a plate extruding device, and feeding the materials into an extruding die 6, and uniformly distributing the molten materials in the die for extrusion and molding by extrusion and flowing force. The temperature setting of the extrusion die is mainly used for molding, adjusting the flow rate and the surface brightness, and because the melt enters the die, the melt is converted into a thin-wall melt with a required shape from a cylinder under the guide of a flow dividing cone, and the temperature of the melt of the parison can be uniformly increased to an optimal plasticizing degree area by means of the external heating of a heating device. The die temperature is thus directly related to the external shaping quality of the product, it being noted that when the extruded product is slightly poorly plasticized, it can also be solved by suitably increasing the die temperature.
(5) Cooling, directly feeding the extruded plate into a cooling device 7, and cooling and shaping the plate by circulating cooling water on the cooling device 7.
(6) The shaped plate enters a traction device 8 through a conveying line, the traction device 8 comprises an upper layer roller and a lower layer roller, a plate channel is arranged between the upper layer roller and the lower layer roller, and surfaces with larger friction coefficients are arranged on the surfaces of the upper layer roller and the lower layer roller. The plate enters the plate channel, and the plate runs on the production line by the rotation traction of the upper layer roller and the lower layer roller.
(7) Cutting to the required sheet size by means of the cutting device 9.
The material of the plate material specified in the present embodiment is not limited to biological straw and plastic, but may be silica gel, PVC, PE, PP, biomass, composite material, or the like, as long as the material can be used as the material of the plate material.
While the foregoing has been provided by embodiments of the present invention with particularity, the principles and modes of carrying out the embodiments of the present invention have been described in detail by way of example only, and are not intended to limit the invention to the particular embodiments and modes of carrying out the invention, as will be apparent to those skilled in the art from consideration of this disclosure.
