DETAILED DESCRIPTION

[0017] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0018] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0019] Reference Figure 1 - Figure 5 , a stone paper manufacturing device, comprising: A base 1, on the top of which a crushing box 2, a mixing box 43 and a making box 51 are installed; A mixing mechanism 4, which is located inside the mixing box 43 and is used to mix the required materials; A winding mechanism 5, which is located inside the production box 51 and is used to press the mixed material into a film; The flow guide mechanism 7 is located between the crushing box 2 and the base 1 and is used to guide the crushed materials into the mixing box 43. The flow guide mechanism 7 includes a flow guide box 71 installed at the bottom of the crushing box 2, an opening and closing mechanism, and a material pushing mechanism. The opening and closing mechanism is located at the bottom of the crushing box 2 and is used to facilitate the circulation of the crushed materials. The material pushing mechanism is located at the bottom of the flow guide box 71 and is used to push the crushed materials. The opening and closing mechanism includes two opening and closing plates 72 hinged at the bottom of the crushing box 2, one side of the two opening and closing plates 72 is equipped with a rotating shaft, the rotating shaft extends to one side of the crushing box 2 and is equipped with a rotating knob, a closing groove 77 is opened inside the guide box 71, a movable block is inserted inside the closing groove 77, and a closing block 75 is fixed to one side of the movable block; The pushing mechanism includes a fourth motor 73 fixed to one side of the guide box 71 and a receiving slot opened on one side of the guide box 71. A pushing block 74 is installed inside the receiving slot. The pushing block 74 is connected to the output end of the fourth motor 73. Two limiting rods 76 are fixed to one side of the pushing block 74. Both limiting rods 76 are plugged into the guide box 71. The mixing mechanism 4 includes a third motor 41 fixed on the top of a mixing box 43. A mixing chamber corresponding to the guide box 71 is provided inside the mixing box 43. A stirring blade 42 is installed inside the mixing chamber. A transmission shaft is connected to the output end of the third motor 41. The transmission shaft extends to the inside of the mixing chamber and is connected to the stirring blade 42. The winding mechanism 5 includes driving motors fixed on both sides of the making box 51, and rollers 52 are installed at the output ends of the two driving motors. The two rollers 52 cooperate with each other. The making box 51 is connected to one side of the bottom of the mixing box 43, and a shielding plate 53 is installed on one side of the top of the making box 51; The winding mechanism 5 further includes two support plates 55 mounted on the top of the base 1, and winding rollers 54 are mounted on opposite sides of the two support plates 55, and the winding rollers 54 correspond to the two roller shafts 52; First, place the stone to be processed in the crushing box 2 and crush it to make it powdery. Turn the rotary knob to drive the rotating shaft to start rotating. The rotation of the rotating shaft drives the opening and closing plate 72 to rotate. The rotation of the opening and closing plate 72 allows the powdery material to enter the guide box 71. Then, pull the opening and closing block 75 to drive the closing block and the closing groove 77 to separate. The fourth motor 73 drives the push block 74 to move. Through the movement of the push block 74, the powdery material at the bottom of the guide box 71 can be effectively pushed until it is pushed into the mixing box 43. The two limit rods 76 are set to make the push block 74 more stable when moving. By pushing the powdery material, its accumulation inside the guide box 71 can be reduced, thereby increasing the discharge efficiency of the present invention.

[0020] like Figure 2 and Figure 3 As shown, since a movable block is inserted into the closing groove 77 and a closing block 75 is fixed on one side of the movable block, the setting of the closing block can effectively prevent the push block 74 from shrinking and causing the material to flow back from the mixing box to the crushing box.

[0021] The third motor 41 drives the transmission shaft to start rotating, and the rotation of the transmission shaft drives the stirring blade 42 to rotate. The rotation of the stirring blade 42 enables the material inside the mixing box 43 to be fully mixed, so as to achieve further processing of the material. Finally, the processed mixed material is transported to the production box 51, and the roller 52 is driven by the driving motor to rotate. Through the rotation of the roller 52, the material can be pressed into a film, thereby forming the initial shape of the stone paper, and then aligned with the winding roller 54. Through the setting of the winding roller 54, the initial shape of the stone paper can be effectively rolled up, which is convenient for its transportation and the next step of processing and production.

[0022] It should be noted that if Figure 2 and Figure 3 A rotatable opening and closing door is obviously installed on one side of the mixing box 43, and the opening and closing door is a hinged door commonly seen on the market. Therefore, the mixing box 43 can be opened through the opening and closing door, so as to realize the transfer of materials to the production box.

[0023] Reference Figure 6 and Figure 7 A disassembly mechanism 6 is provided between the two support plates 55 and the base 1 to facilitate disassembly of the support plates 55. The disassembly mechanism 6 includes a disassembly block 63 fixed to the bottom of the support plate 55. A disassembly slot for inserting the disassembly block 63 is provided on the top of the base 1, and two disassembly rods 64 are inserted inside the base 1. A jack for inserting the disassembly rods 64 is provided inside the disassembly block 63. A control mechanism for controlling the disassembly rods 64 is provided between the two disassembly rods 64 and the base 1; The control mechanism includes a frame 66 fixed on one side of the base 1, two disassembly and assembly rods 64 extend to one side of the base 1 and are jointly installed with a moving plate 65, a linkage rod 61 is fixed to one side of the moving plate 65, the linkage rod 61 extends to one side of the frame 66 and is installed with a control plate, and a spring 62 is connected between the moving plate 65 and the frame 66.

[0024] When it is necessary to disassemble the winding roller 54, the control plate 61 is first pulled to drive the linkage rod 61 to move, and the movement of the linkage rod 61 drives the moving plate 65 to move, and the movement of the moving plate 65 drives the disassembly rod 64 to move, and the disassembly rod 64 is moved to separate it from the disassembly block 63. After the disassembly rod 64 and the disassembly block 63 are separated from each other, the support plate 55 is pulled to drive the disassembly block 63 to move, so that the disassembly block 63 is separated from the disassembly groove, so that the support plate 55 can drive the winding roller 54 to separate, and then the disassembly operation of the winding roller 54 is completed. By disassembling the winding roller 54, it is convenient for the user to maintain and repair it, and the winding roller 54 that has been wound up can be replaced.

[0025] Reference Figure 1 - Figure 4 A crushing mechanism 3 for crushing stones is arranged inside the crushing box 2, and the crushing mechanism 3 includes a first motor 34 and a second motor 35 fixed on one side of the crushing box 2, a reinforcement plate is fixed between the first motor 34 and the second motor 35, and a connecting plate 36 is fixed between the reinforcement plate and the crushing box 2, a first crushing roller group 31 and a second crushing roller group 33 are arranged inside the crushing box 2, and matching belts 37 are installed between the first crushing roller group 31 and the second crushing roller group 33, one side of the first crushing roller group 31 is respectively connected to the output ends of the first motor 34 and the second motor 35, a positioning block 38 for dividing the first crushing roller group 31 and the second crushing roller group 33 is arranged inside the crushing box 2, and a guide plate 32 is installed on the top of the crushing box 2, and the guide plate 32 corresponds to the first crushing roller group 31.

[0026] By setting the first motor 34 and the second motor 35, the two belts 37 can rotate synchronously. By the rotation of the two belts 37, the first crushing roller group 31 and the second crushing roller group 33 can rotate synchronously. By the rotation of the first crushing roller group 31, the stone raw material can be crushed for the first time. Then, by the setting of the second crushing roller group 33, the material after the first crushing can be crushed again. By the mutual cooperation of the first crushing roller group 31 and the second crushing roller group 33, the stone can be efficiently crushed, ensuring that the stone reaches the required particle size in a shorter time, thereby improving the production speed and the overall production efficiency.
