[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0021] Please see Figures 1-5 As shown, the present invention is a split-type dual-station rapid roll-changing calender, including a machine body 1 and a flat frame 11. When the sheet passes through a one-roller device 12 and a two-roller device 13, the lower surface is embossed by the one-roller device 12. Then, the sheet passes through a three-roller device 14 and a two-roller film-coating device 15 to coat its upper surface. After passing through a heat preservation device 16, the upper surface of the sheet is embossed by a four-roller device 17 and a fifth roller 18. Subsequent processes such as slitting and trimming are then performed.

[0022] Furthermore, the flat frame 11 includes a modularly configured first frame 111, a second frame 112, and a third frame 113. A one-roller device 12, a two-roller device 13, a three-roller device 14, and a double-roller coating device 15 are mounted on the first frame 111, the double-roller coating device 15 is mounted on the second frame 112, and a four-roller device 17 and a fifth roller 18 are mounted on the third frame 113. The modules are connected by conventional bolts, which are not shown in the figure.

[0023] Furthermore, there are two fifth rollers 18. The two fifth rollers 18 are engaged with the four-roller device 17 from different radial angles via electric gate openers 2 for texturing. The electric gate opener 2 is a screw-type structure driven by a motor. The screw is the movable end and is rotatably connected to the bearing seat 3 to transmit the axial movement force after the screw rotates, thereby realizing the movement of the fifth rollers 18. The two fifth rollers 18 are engaged with or disengaged from the four-roller device 17 by switching between the two sets of electric gate openers 2.

[0024] Furthermore, the fifth roller 18 is detachably connected to the movable end of the electric gate hoist 2 via the bearing seat 3. The bearing seat 3 includes a lower seat body 31 and an upper seat body 32 hinged to one end of the lower seat body 31 via a rotating connecting plate 33. The other end of the lower seat body 31 is hinged with a live bolt 34 that cooperates with the U-shaped block 321. The live bolt 34 is also provided with a nut 35. In this embodiment, the hinge of the upper seat body 32 and the lower seat body 31 via the rotating connecting plate 33 facilitates the disassembly and assembly of the fifth roller 18. The live bolt 34 is embedded in the U-shaped block 321 and the screw of the nut 35 is used for locking after the fifth roller 18 is connected, ensuring the reliability of the connection between the fifth roller 18 and the bearing seat 3 after the connecting bearing 181 is connected.

[0025] Furthermore, a four-roller device 17 is mounted on the third frame 113 by a motor drive. A transverse support 1131 located on the horizontal left side of the four-roller device 17 and a longitudinal support 1132 located vertically above it are fixed on the third frame 113. Two sets of electric hoists 2 and bearing seats 3 are installed on them respectively. The rotation angle of the upper seat 32 in the transverse support 1131 is 180°. For safety, the rotation angle of the upper seat 32 in the longitudinal support 1132 is 90°.

[0026] Furthermore, two sets of electric gate hoists 2 are respectively installed on the transverse support 1131 and the longitudinal support 1132 to drive the fifth roller 18 to cooperate with the four-roller device 17. During operation, only one fifth roller 18 is in contact with the four-roller device 17. The surface texture of the fifth roller 18 is used to emboss the upper surface of the plate. When switching is required, the electric gate hoist 2 moves the fifth roller 18 cooperating with the four-roller device 17 radially away. Then, the other set of electric gate hoists 2 moves the fifth roller 18 at its upper end to the position cooperating with the four-roller device 17. Then, the fifth roller 18 in the non-working state is replaced through the bearing seat 3.

[0027] Furthermore, a sliding member 4 is provided between the bearing housing 3 and the third frame 113. The sliding member 4 consists of a slide rail and a slide seat. The slide seat is directly fixed to the lower seat 31 in the bearing housing 3. The slide rail is installed on the flat machine frame 11. The sliding member 4 is used to support the fifth roller 18 sliding on the flat machine frame 11.

[0028] Furthermore, a bearing groove 36 is provided between the lower seat 31 and the upper seat 32, and connecting bearings 181 that cooperate with the bearing groove 36 are provided at both ends of the fifth roller 18. The inner ring of the connecting bearing 181 is fixed to the fifth roller 18, and the outer ring is pressed when the lower seat 31 and the upper seat 32 are locked. Then, the fifth roller 18 rotates on the bearing seat 3 under the action of the connecting bearing 181.

[0029] Furthermore, the machine body 1 is also equipped with a heat preservation device 16 located between the three-roller device 14 and the four-roller device 17. The core function of the heat preservation device 16 is to accurately maintain and control the temperature of the board that has been coated on the upper surface but has not yet undergone final embossing. By preventing the temperature of the board from dropping below the process requirements due to heat loss during the process flow, this device ensures that the board, especially the stone-plastic composite material, is always in the best plastic state, thereby ensuring the forming quality and pattern clarity when embossed by the four-roller device 17 and the fifth roller 18.

[0030] Furthermore, the electric gate opener 2 is specifically a screw-driven mechanism, with a motor providing the core power. Its working mechanism involves the motor driving the screw to rotate, which serves as the moving end of the electric gate opener and forms a rotatable connection with the bearing housing 3. This design efficiently converts the rotational motion of the motor into the axial linear motion of the screw, thereby precisely pushing or pulling the connected bearing housing 3 and the fifth roller 18, achieving their pressing or separation from the four-roller device 17. The screw drive method has advantages such as large thrust, precise positioning, and good self-locking performance, ensuring stable and sufficient pressure between the fifth roller 18 and the four-roller device 17 during the embossing process. Simultaneously, it can reliably disengage and accurately position itself when roller changes are required, providing stable and reliable execution power for rapid roller changes.

[0031] Furthermore, to realize the core advantages of the modular design, the connection between the first frame 111, the second frame 112, and the third frame 113 of the flat frame 11 of this calender is achieved using bolted connections. Specifically, corresponding connection holes are pre-set on the mating surfaces of each modular frame, and high-strength bolts and nuts are used to tightly fix each frame into a rigid, integrated structure. This connection method not only ensures the overall rigidity and stability required for the equipment during operation to withstand the enormous pressure generated by the rolling process, but more importantly, it greatly facilitates on-site installation, subsequent maintenance, and long-distance transportation. When relocation or entry into a specific space is required, simply removing the connecting bolts allows the entire machine to be disassembled into multiple easily transportable modules, overcoming the inherent defects of inconvenient transportation in traditional integrated structures and significantly improving the equipment's site adaptability and logistical economy.

[0032] It is understood that the present invention adopts a split modular flat frame design, which allows for quick replacement of parts according to production needs and facilitates disassembly and transportation; at the same time, it is equipped with a fifth roller in both the transverse and longitudinal directions and an electric gate opener, so as to realize roller replacement without stopping the machine during production to improve efficiency, and the detachable bearing seat structure ensures the stability of the roller installation while simplifying maintenance operations.
