[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a pressing and edging device for the production of paper-faced gypsum boards, including a support frame 1, and a conveyor belt 22 is rotatably arranged on the upper end surface of the support frame 1.

[0025] Specifically, rotating rollers 23 are rotatably arranged on both sides of the upper end surface of the support frame 1, and the conveyor belt 22 is sleeved on the outer sides of the two rotating rollers 23. Both ends of the rotating roller 23 are rotatably installed with support plates 21, and the bottom ends of the support plates 21 are fixedly installed on the upper end surface of the support frame 1. A motor 24 is fixedly installed on one of the support plates 21, and the output shaft of the motor 24 is fixedly connected to the corresponding rotating roller 23.

[0026] L-shaped fixing frames 2 are fixedly installed on both sides of the upper end surface of the support frame 1 corresponding to the conveyor belt 22, and the two L-shaped fixing frames 2 are arranged in a mirror image.

[0027] U-shaped frames 3 are slidably arranged on the L-shaped fixing frames 2.

[0028] Specifically, a plurality of sliding columns 6 are fixedly installed on the upper end surfaces of the U-shaped frames 3, and the sliding columns 6 are all slidably connected to the L-shaped fixing frames 2. Springs 7 are fixedly connected to the U-shaped frames 3 at positions corresponding to the sliding columns 6, and the top ends of the springs 7 are fixedly connected to the L-shaped fixing frames 2.

[0029] A plurality of edge pressing wheels 4 are rotatably mounted inside the U-shaped frame 3. The edge pressing wheels 4 correspond to the conveyor belt 22.

[0030] The interval between the pressing wheel 4 and the conveyor belt 22 is smaller than the thickness of the gypsum board.

[0031] The top ends of the two L-shaped fixing frames 2 are fixedly mounted with a mounting box 20, a rotating shaft is rotatably mounted inside the mounting box 20, and a fan 17 is fixedly mounted at the bottom end of the rotating shaft. A linkage assembly is arranged between the edge pressing wheel 4 and the rotating shaft.

[0032] Further, the linkage assembly includes a rotating shaft 5, a first bevel gear 8, a second bevel gear 9, a transmission shaft 13, a first pulley 14, a belt 15 and a second pulley 16. The rotating shaft 5 is rotatably mounted on one side of the U-shaped frame 3, and the rotating shaft 5 is fixedly connected to one of the edge pressing wheels 4.

[0033] It should be noted that the edge pressing wheel 4 connected to the rotating shaft 5 is located near the entrance of the gypsum board, so that when the gypsum board starts to be edge pressed, the rotating shaft 5 is driven to rotate through the edge pressing wheel 4.

[0034] The other end of the rotating shaft 5 is fixedly connected to the first bevel gear 8. A fixing plate 11 is fixedly connected to the outer side of the U-shaped frame 3, and a second bevel gear 9 is rotatably mounted on the fixing plate 11. The second bevel gear 9 is meshed and connected with the first bevel gear 8. The transmission shaft 13 is fixedly mounted on the L-shaped fixing frame 2. The transmission shaft 13 is engaged with the second bevel gear 9.

[0035] Specifically, a spline groove 12 is fixedly installed at the bottom end of the transmission shaft 13, a spline 10 is rotatably installed on the fixing plate 11, and the second bevel gear 9 is fixedly installed at the bottom end of the spline 10. The spline 10 is plug-fitted with the spline groove 12.

[0036] A first pulley 14 is fixedly connected to the top end of the transmission shaft 13 , a second pulley 16 is fixedly connected to the top end of the rotating shaft, and the first pulley 14 and the second pulley 16 are connected in transmission via a belt 15 .

[0037] A fixed shaft 18 is fixedly installed between the two L-shaped fixing frames 2 in the installation box 20 , and a heating wire 19 is wound around the outer side of the fixed shaft 18 .

[0038] Working principle:

[0039] During use, the heating wire 19 is electrified to heat up, the motor 24 is started, the motor 24 drives the rotating roller 23 to rotate, and then drives the conveyor belt 22 to rotate. The gypsum board is placed on the conveyor belt 22. Since the interval between the edge pressing wheel 4 and the conveyor belt 22 is smaller than the thickness of the gypsum board, when the gypsum board is transported under the edge pressing wheel 4, with the transportation of the conveyor belt 22, the gypsum board will push the edge pressing wheel 4 and the U-shaped frame 3 upward. The U-shaped frame 3 drives the sliding column 6 to slide upward in the L-shaped fixing frame 2 to move the U-shaped frame 3 upward, causing the spring 7 to be compressed. At the same time, the spring 7 will provide a thrust to the edge pressing wheel 4 so that the edge pressing wheel 4 can press the gypsum board tightly, flattening the paper surface at the edge of the gypsum board.

[0040] During the transportation of the gypsum board, due to the frictional force between the gypsum board and the edge pressing wheel 4, the edge pressing wheel 4 will rotate. It should be noted that the edge pressing wheel 4 connected to the rotating shaft 5 is located at a position close to the entrance of the gypsum board, so that when the gypsum board starts to be edge-pressed, the gypsum board drives the rotating shaft 5 to rotate through the edge pressing wheel 4.

[0041] The edge pressing wheel 4 drives the rotating shaft 5 and the first bevel gear 8 to rotate. The first bevel gear 8 drives the engaged second bevel gear 9 to rotate. The second bevel gear 9 drives the transmission shaft 13 to rotate through the spline 10.

[0042] While the U-shaped frame 3 moves upward, the fixing plate 11 drives the spline 10 to slide upward in the spline groove 12, thus not affecting the transmission between the spline 10 and the transmission shaft 13.

[0043] The transmission shaft 13 drives the first pulley 14 to rotate to make the belt 15 and the second pulley 16 rotate. The second pulley 16 drives the rotating shaft to rotate, and then drives the fan 17 to rotate to blow the heat generated by the heating wire 19 towards the gypsum board, thereby accelerating the drying of the gypsum board. After the gypsum board passes through the edge pressing wheel 4, the fan 17 stops rotating. It saves energy and reduces the use cost.

[0044] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
