In addition, the provision of a cutter increases the complexity of the apparatus. In addition, the gypsum is generally molded and conveyed by a conveying belt, and the conveying belt is flexible and easy to deform, so that the dimensional accuracy of gypsum board molding is difficult to ensure. In addition, also adopt the conveyer belt to drive the gypsum board and remove in the drying furnace during the stoving, because the lower surface of gypsum board is with the conveyer belt contact, moisture is difficult to evaporate, consequently need turn over the gypsum board in the midway of stoving, current turn over mechanism structure is complicated, like prior art such as CN213678704U, implementation cost is high.

The mixing mechanism 1 is used to mix various raw materials to produce gypsum slurry. As shown in FIG. 2, the mixing mechanism 1 comprises a feeding sleeve 12, a mixing drum 11 and a discharging sleeve 13 which are sequentially and coaxially arranged, wherein the mixing drum 11 is obliquely arranged, the lower end of the feeding sleeve 12 extends into the upper end of the mixing drum 11 and is in rotary fit with the mixing drum 11, the inner diameter of the discharging sleeve 13 is larger than that of the mixing drum 11, the lower end of the mixing drum 11 extends into the discharging sleeve 13 and is in rotary fit with the discharging sleeve 13, and the mixing drum 11 is connected with a rotary driving mechanism 16 for driving the mixing drum 11 to rotate; the top of feeding sleeve 12 is provided with feed inlet 14, and the bottom of ejection of compact sleeve 13 is provided with discharge gate 15 and seals the closing mechanism of discharge gate 15, and discharge gate 15 is located the top of feed section 24.
The feeding sleeve 12 and the discharging sleeve 13 are fixedly installed on the frame, the mixing drum 11 is rotatably installed on the frame, and the inclination angle of the mixing drum 11 is 1.5 to 2.5 degrees.

The rolling driving mechanism is used for driving the press roller 211 to roll back and forth, as the press roller 211 does not only rectilinear motion but also rotary motion, racks can be arranged, gears meshed with the racks are arranged at two ends of the press roller 211, a motor is arranged at one end of the press roller 211, the motor drives the press roller 211 to rotate when rotating, the press roller 211 drives the gears to rotate when rotating, and the press roller 211 does rectilinear motion along the length direction of the racks under the action of the racks. However, the driving mode is complex in structure, the rack and pinion mechanism cannot stably position the pressing roller 211 with larger weight, and because the pressing roller 211 is used for compacting the gypsum board in the process of compacting the gypsum board, the compactness of the gypsum board is continuously increased, and the thickness of the gypsum board is reduced, so that the height of the top board 23 is reduced, and in order to ensure that the gravity of the pressing roller 211 is transferred to the gypsum board, the height of the pressing roller 211 is reduced along with the lowering of the top board 23, which cannot be realized by the conventional driving mechanism, so that the pressing roller 211 is difficult to fully compact the gypsum board by utilizing the weight of the pressing roller 211.
In order to solve the defects of the conventional rolling driving mechanism, the rolling driving mechanism comprises a supporting frame 212 arranged at the outer side of a side plate 22, as shown in fig. 5 and 6, a fixed supporting plate 217 is arranged between the two supporting frames 212, the upper surface of the fixed supporting plate 217 is flush with the lower surface of a baffle post 29, a fit clearance is arranged between the end surface of the fixed supporting plate 217 and the end surface of a top plate 23, and a press roller 211 can be supported by the fixed supporting plate 217; the two ends of the press roller 211 are provided with sliding blocks 213, the sliding blocks 213 are in sliding fit with the supporting frame 212, the two end surfaces of the press roller 211 are provided with annular sliding grooves 214, rollers 215 in sliding fit with the sliding grooves 214 are arranged in the sliding grooves 214, and the rollers 215 are connected with a linear driving mechanism 216 for driving the rollers 215 to reciprocate in a linear mode.
The fixed support plate 217 is disposed in front of the extrusion section 25, and the fixed support plate 217 supports the press roller 211 during non-compression molding, so that a slight gap is formed between the end surface of the fixed support plate 217 and the end surface of the top plate 23, and the upper surface of the fixed support plate 217 is flush with the lower surface of the stopper 29 (i.e., the upper surface of the top plate 23), thereby ensuring that the press roller 211 can stably roll from the fixed support plate 217 onto the top plate 23 during compression. The sliding block 213 is in sliding fit with the supporting frame 212, and when the pressing roller 211 moves, the supporting frame 212 plays a role in guiding and positioning, so that the pressing roller 211 can move stably. The roller 215 is located at the upper part of the press roller 211 and is deviated from the center of the press roller 211, when the linear driving mechanism 216 applies a pushing force to the roller 215, the roller 215 transmits the pushing force to the side wall of the chute 214, and the acting force deviates from the center of gravity of the press roller 211, so that the roller 215 can be driven to roll. The linear driving mechanism 216 may be a hydraulic cylinder, one end of which is hinged to the support frame 212, and an inclined telescopic support rod is provided below the hydraulic cylinder, and when the height of the press roller 211 is lowered, the hydraulic cylinder may be deflected downward, and the telescopic support rod is compressed to be shortened.
In the process of pressing gypsum slurry, the thickness of the gypsum slurry is reduced, the height of a top plate 23 is gradually reduced, in order to ensure that a pressing roller 211 descends synchronously along with the descending of the top plate 23, so that the gravity of the pressing roller 211 can be always and effectively transferred to the top plate 23 and the gypsum slurry.
Because the lifting block 223 is in sliding fit with the upright post 224, when the height of the top plate 23 is reduced, the pressing roller 211 descends synchronously with the top plate 23 under the action of gravity, at this time, the lifting block 223 descends synchronously with the pressing roller 211, the lower spring is compressed, and the height of the whole sliding block 213 is kept unchanged, so that the sliding fit with the supporting frame 212 can be kept.
After the pressing is completed, the top plate 23 may be lower than the fixed support plate 217, and in order to ensure that the pressing roller 211 rolls smoothly from the top plate 23 to the fixed support plate 217, an axial anti-slip boss may be disposed on the outer circumferential surface of the pressing roller 211, and the anti-slip boss may be a rectangular boss, a body-shaped boss or a triangular boss.
Since the top plate 23 is to be moved up and down, in order to improve stability of the top plate 23, the upper surface of the top plate 23 is provided with a plurality of vertical guide posts 219, the guide posts 219 penetrate through the stopper posts 29 and are slidably engaged with the stopper posts 29, the upper ends of the guide posts 219 are provided with a retainer ring plate 220, and springs 221 are provided between the retainer ring plate 220 and the stopper posts 29. When the gypsum slurry is not pressed, the top plate 23 is stably positioned on the lower surface of the stopper 29 by the spring 221.
Because the water content in the gypsum slurry is higher, in the compression molding process, partial water in the gypsum slurry is extruded, in order to discharge the water, the water content of the gypsum board is reduced, so that the subsequent drying efficiency is improved, a plurality of water leakage holes are formed in the support platform 21 at the bottom of the extrusion molding section 25, the diameter of the upper end of each water leakage hole is smaller than that of the lower end, and a water receiving groove 218 is formed below each water leakage hole. The squeezed water can flow into the water receiving tank 218 through the water leakage holes, and the water in the water receiving tank 218 can be reused for the preparation of gypsum slurry. Part of the gypsum slurry can enter the water leakage hole, and the water leakage hole is formed into a circular truncated cone-shaped hole with a small upper end and a large lower end, so that the gypsum slurry can be prevented from blocking the water leakage hole, and the water leakage efficiency is ensured.
The conveying mechanism 5 may be a conventional conveying device such as a conveying roller, and a conveying belt is preferably used.
The drying mechanism 3 is used for drying the gypsum board, specifically, as shown in fig. 7, the drying mechanism 3 includes a drying chamber 31, a heating mechanism 32 and a blowing mechanism 33 are disposed in the drying chamber 31, the conveying belt penetrates through the drying chamber 31, and an air outlet of the blowing mechanism 33 faces the conveying belt.
The outer wall of the drying chamber 31 is provided with a heat insulating material to reduce heat loss. The drying chamber 31 is provided at both ends with inlet and outlet openings for gypsum board and conveyor belts. The conveyor belt conveys the pressed gypsum board to the drying chamber 31, the heating mechanism 32 generates heat to make the inside of the drying chamber 31 at a proper high temperature, and the blowing mechanism 33 blows hot air in the drying chamber 31 to the gypsum board to rapidly take away moisture of the gypsum board and promote drying of the gypsum board.
In the drying process, as the ground of the gypsum board is contacted with the conveying belt, the heat transfer speed is low, the water evaporation speed is low, so that the top and four side surfaces of the gypsum board are dried more quickly, the bottom surface is dried slowly, the gypsum board needs to be turned over after being dried for a period of time in order to improve the drying efficiency, and the existing turning-over equipment is complex in structure and high in implementation cost. Therefore, the invention improves a turnover mode with simple structure and convenient control, and particularly:
the conveyor belt in the drying chamber 31 includes a first conveyor belt 34, a second conveyor belt 35 and a third conveyor belt 36, the first conveyor belt 34 includes a first inclined section 341, a second inclined section 342 and a third inclined section 343, the first inclined section 341 is inclined from bottom to top, the second inclined section 342 is inclined from top to bottom, the third inclined section 343 is located below the second inclined section 342 and inclined from top to bottom, the second conveyor belt 35 is horizontally disposed and located below the lower end of the second inclined section 342, the third conveyor belt 36 is horizontally disposed and connected with the second conveyor belt 35, the conveying directions of the first conveyor belt 34 and the third conveyor belt 36 are the same, and the conveying directions of the second conveyor belt 35 are alternately changed.
The gypsum board is moved with the first inclined section 341 and the second inclined section 342, and the top and side surfaces are gradually dried, and the first inclined section 341 drives the gypsum board to move to a higher position so that the gypsum board has a proper height after the gypsum board is subsequently transferred to the second and third conveyor belts 35 and 36. The gypsum board moves along with the second inclined section 342, finally falls onto the second conveying belt 35, the included angle between the second inclined section 342 and the horizontal plane is larger, the gypsum board is ensured to fall on the second conveying belt 35 and is close to a vertical state, the second inclined section 342 can be divided into a plurality of sections, and the included angle between each section and the horizontal plane is gradually increased. Assuming that the conveying direction of the first conveying belt 34 and the third conveying belt 36 is forward, when the gypsum board falls on the second conveying belt 35, the conveying direction of the second conveying belt 35 is backward, at this time, the friction force of the second conveying belt 35 to the lower part of the gypsum board is backward, so that the lower part of the gypsum board is driven to move backward, but the upper part of the gypsum board is blocked by the second inclined section 342 and cannot move backward, so that the second inclined section 342 pushes the gypsum board to turn over onto the second conveying belt 35, after the gypsum board is turned over, the second conveying belt 35 is switched to move forward, the turned gypsum board is conveyed to the third conveying belt 36, the third conveying belt 36 continues to drive the gypsum board to move forward, and after the top surface (original bottom surface) of the turned gypsum board is dried, the gypsum board is conveyed out of the drying chamber 31.
The turnover structure of the invention adopts a transmission belt, and has simple structure and low implementation cost.
