DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Please refer to Figure 1 , 2 , the production process of gypsum board is:

[0027] Two folds are engraved on both sides of the lower face paper 12, and the lower face paper 12 is turned up into a C-shape with the opening upward by the turning structure 13, and at the same time, gypsum slurry is sprayed on the inside of the lower face paper 12 passing through the top of the forming plate 1;

[0028] The upper face paper 11 is guided by the guide roller 14 to be pasted on the flange at the top of the lower face paper 12, and the gypsum slurry is trapped in the rectangular cavity surrounded by the upper face paper 11 and the lower face paper 12, and the gypsum slurry naturally spreads and fills every gap in the cavity;

[0029] The two sides of the lower face paper 12 are squeezed by the edge standing board 2, so that the two sides of the lower face paper 12 become vertical and flat, and the upper face paper 11 is squeezed by the squeezing board 15, so that the upper face paper 11 becomes horizontal and flat;

[0030] Then the upper face paper 11, the lower face paper 12 and the gypsum slurry inside the two are moved to the forming belt 16 for further transmission. After the gypsum slurry solidifies into a wet gypsum board, it is cut and dried to obtain a gypsum board.

[0031] During the production process of gypsum board, affected by many factors such as local temperature, expansion of facing paper after being damp, expansion of gypsum slurry during solidification, movement of gypsum board on forming belt 16, position of chamfering belt on forming belt 16, etc., the angle between the two side walls and the upper and lower walls of the gypsum board is prone to not being 90° after initial setting, i.e., chamfering of the gypsum board.

[0032] In particular, when both sides of the wet gypsum board are pressed up and down by the screed plate 17 and the chamfering belt 18 on the forming belt 16 to form chamfers, the thickness of the side wall of the wet gypsum board is reduced, making it more likely to have technical problems of chamfering and rounding.

[0033] In order to solve the above problem, it is necessary to pre-incline the angle of the vertical edge board 2 when squeezing the two sides of the lower protective paper 12, so that the two side walls of the gypsum board move to the forming belt 16 in a shape other than a 90° right angle, and the two side walls of the gypsum board are transformed into a 90° right angle after being squeezed up and down by the screed plate 17 and the chamfering belt 18.

[0034] The following is a gypsum board vertical edge mechanism with chamfer compensation, please refer to Figure 3 .

[0035] The gypsum board edge-standing mechanism comprises edge-standing boards 2, a turntable 3, and a driver 4 which are arranged in pairs on both sides of a forming board 1;

[0036] The turntable 3 is connected to the frame, and the distance between the two turntables 3 can be adjusted;

[0037] The turntable 3 is rotatably connected to the vertical edge board 2 via a first rotating shaft 31, so that the vertical edge board 2 can rotate around the axis of the first rotating shaft 31, and the axis of the first rotating shaft 31 is parallel to the transmission direction of the gypsum board;

[0038] The driver 4 is fixedly connected to the turntable 3, and the actuator of the driver 4 is drivingly connected to the vertical edge plate 2. The driver 4 is used to drive the vertical edge plate 2 to rotate around the first rotating shaft 31;

[0039] The vertical edge board 2 comprises a working surface 21 facing the other vertical edge board 2 , the working surface 21 is parallel to the conveying direction of the gypsum board and is substantially perpendicular to the molding board 1 , and the bottom edge of the working surface 21 is adjacent to the top wall of the molding board 1 .

[0040] The staff detects the inclination angle of the two side walls of the gypsum board downstream of the production line, that is, after the wet gypsum board passes through multiple screed plates 17. If the detected inclination angle is greater than the standard angle or the allowable angle threshold range, the upper part of the vertical edge board 2 is adjusted inward; if the detected inclination angle is less than the standard angle or the allowable angle threshold range, the upper part of the vertical edge board 2 is adjusted outward.

[0041] Specifically: the vertical edge plate 2 is a three-dimensional rectangular flat plate, one side wall of the vertical edge plate 2 forms a working surface 21, and an angle is formed between the bottom wall 22 of the vertical edge plate 2 and the working surface 21. The angle is an acute angle, and the difference between the angle and 90° is less than the rotation stroke of the working surface 21.

[0042] Since the height of the vertical edge board 2 is relatively low, the installation space of the driver 4 is limited, and the rotation angle of the vertical edge board 2 is relatively small, so it is necessary to arrange the driver 4 that can drive the vertical edge board 2 to rotate with high precision in the limited installation space. The following provides a preferred structure of the driver 4, please refer to Figure 3 , 5 -7.

[0043] The driver 4 includes: a connecting rod 41, a first slider 42, a first slide 43, a second slider 44, a second slide 45 and a servo electric cylinder 46;

[0044] The first slider 42 is slidably connected to the turntable 3 through the first slide 43. The sliding direction of the first slider 42 is perpendicular to the axis of the first rotating shaft 31. The two ends of the connecting rod 41 are respectively hinged to the vertical edge plate 2 and the first slider 42 through the second rotating shaft 411 and the third rotating shaft 412. The axes of the first rotating shaft 31, the second rotating shaft 411 and the third rotating shaft 412 are parallel.

[0045] The second slider 44 is slidably connected to the turntable 3 via the second slide 45. The sliding direction of the second slider 44 is parallel to the axis of the first rotating shaft 31. The actuator of the servo electric cylinder 46 is fixedly connected to the second slider 44. The servo electric cylinder 46 is used to drive the second slider 44 to slide along the second slide 45.

[0046] The second slider 44 is connected to the first slider 42 via an oblique guide structure 47 , so that when the second slider 44 slides along the second slide 45 , the first slider 42 slides along the first slide 43 , thereby pushing the vertical edge plate 2 to rotate around the first rotation axis 31 through the connecting rod 41 .

[0047] The driver 4 converts the larger stroke of the second slider 44 into the smaller stroke of the first slider 42 through the oblique guide structure 47, so that the narrow space inside the turntable 3 can also accommodate the larger servo cylinder 46. At the same time, the actuator of the servo cylinder 46 needs to move a larger stroke to drive the vertical edge plate 2 to perform a smaller angle change, thereby improving the rotation accuracy of the vertical edge plate 2.

[0048] Specifically, the oblique guide structure 47 includes: an oblique slide rail 471 and an oblique slide groove 472;

[0049] The inclined slide rail 471 is disposed on the second slider 44, and the inclined slide groove 472 is disposed on the first slider 42, and the inclined slide rail 471 and the inclined slide groove 472 are slidably connected;

[0050] The inclined slide rail 471 extends along a first straight line, and the first slide block 42 slides along a second straight line;

[0051] The first straight line, the second straight line and the axis of the third rotating shaft 412 all fall on the same plane, and the axis of the second straight line and the axis of the third rotating shaft 412 all intersect with the first straight line.

[0052] Preferably, the angle between the first straight line and the axis of the third rotating shaft 412 is between 5° and 10°. A smaller angle can increase the stroke of the second sliding block 44 and improve the rotation accuracy of the edge plate 2.

[0053] Preferably, the second slider 44 slides along the third straight line, the first straight line and the third straight line fall on the same plane and intersect each other, and the first straight line, the second straight line and the third straight line all fall on the same plane, so that the force applied to the first slider 42 by the vertical edge plate 2 through the connecting rod 41 can be directly transmitted to the turntable 3, and no torque is generated on the second slider 44 to drive it to flip, so that the driver 4 can operate more stably.

[0054] On the other hand, in order to facilitate the operator to adjust the distance between the two vertical edge boards 2 so that the distance between the two vertical edge boards 2 is equal to the width of the gypsum board, a preferred embodiment is provided below, please refer to Figure 4 .

[0055] A crossbeam 5 is arranged above the forming board 1, and two ends of the crossbeam 5 are respectively arranged on both sides of the forming board 1, and two screw slides 51 are fixedly installed on the crossbeam 5. The third sliders 52 of the two screw slides 51 are respectively fixedly connected to the two turntables 3, and the sliding direction of the third slider 52 is horizontal and perpendicular to the transmission direction of the gypsum board.

[0056] The operator can adjust the positions of the two turntables 3 through the screw slide 51 , thereby changing the distance between the two side panels 2 .

[0057] Both ends of the cross beam 5 are respectively mounted on two columns 53 , and the columns 53 are provided with external threads. At least two nuts 54 are mounted on each column 53 , and the two nuts 54 are respectively against the upper and lower surfaces of the cross beam 5 .

[0058] The operator can change the height of the two ends of the crossbeam 5 by adjusting the height of the nut 54, and then adjust the bottom edge of the working surface 21 of the vertical edge plate 2 to be parallel to the forming plate 1, thereby avoiding scratches between the bottom edge of the working surface 21 of the vertical edge plate 2 and the forming plate 1 when the positions of the two turntables 3 are adjusted by the screw slide 51.

[0059] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
