[0002] The subject matter disclosed in the present invention relates to a device for correcting the vertical edge of a gypsum board. The related technology is disclosed as follows: During the gypsum board forming process, due to the fluctuation of the gypsum slurry discharge and the addition of other auxiliary materials, the vertical edge of the gypsum board formed will be unstable, the edge of the gypsum board will present an acute angle or an obtuse angle, and the vertical edge of the gypsum board cannot be guaranteed. Such unqualified boards cannot be put on the market.

[0003] In the actual production process, the forming of the vertical edge of gypsum board currently relies mainly on the cooperation between the extrusion molding machine and the molding knife, and relies on manual inspection and intervention of the forming vertical edge. If manual inspection is not timely after extrusion molding, a large number of defective products will be produced. Therefore, a gypsum board vertical edge correction device is proposed.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] Currently, the forming of gypsum board vertical edges mainly relies on the cooperation between the extrusion forming machine and the forming knife, and relies on manual inspection and intervention of the forming vertical edges. However, if manual inspection is not timely after the extrusion forming, a large number of defective products will be produced.

[0048] Reference Figure 1-2 A gypsum board vertical edge correction device includes two vertical edge baffles 3, which are symmetrically and movably arranged on both sides of a horizontal conveyor belt 1 and are in contact with the conveying surface of the horizontal conveyor belt 1, and are used to clamp the two vertical edges of the gypsum board 2;

[0049] Two screw slides 4 are symmetrically and fixedly arranged on both sides of the horizontal conveyor belt 1. The actuators of the two screw slides 4 are respectively connected to a vertical edge baffle 3 to drive the vertical edge baffle 3 to move along the conveying surface of the horizontal conveyor belt 1 and perpendicular to the conveying direction of the horizontal conveyor belt 1;

[0050] The clutch 5 is arranged between the two screw slides 4 and connects the screws 402 of the two screw slides 4. When the clutch 5 is operated, it connects or disconnects the transmission connection relationship between the two screw slides 402 so that the two screw slides 4 can work synchronously or separately.

[0051] Reference Figure 3-5The clutch includes a coupling rod 501 and a paddle 502. The paddle 502 is symmetrically arranged at both ends of the coupling rod 501. A slot is provided at one end of the screw rods 402 of each screw slide 4 that is close to each other. The paddle 502 can be inserted into the slot so that the two screw rods 402 can transmit torque through the coupling rod 501.

[0052] Furthermore, the clutch 5 also includes a bearing seat 503, a tubular bracket 504 and a cylindrical slider 505. The bearing seat 503 is connected to the coupling rod 501 so that the coupling rod 501 can rotate around its own axis; the tubular bracket 504 is connected to the frame 6 and the bearing seat 503, and is used to drive the bearing seat 503 to move perpendicular to the conveying surface of the horizontal conveyor belt 1, so that the bearing seat 503 drives the coupling rod 501 to move, thereby allowing the paddle 502 to be embedded in or out of the two slots.

[0053] Furthermore, the tubular bracket 504 is arranged vertically, and the end face of its top is provided with a first limiting groove 506 and a second limiting groove 507 of different depths and perpendicular to each other. The depth of the first limiting groove 506 is less than the depth of the second limiting groove 507. The cylindrical slider 505 can be axially slid and rotatably installed inside the tubular bracket 504. The top is provided with an outwardly extending limiting block 511, and the bottom is fixedly connected to the bearing seat 503. The limiting block 511 can be selectively connected to one of the first limiting groove 506 and the second limiting groove 507, so that the bearing seat 503 is restricted to a high or low position, thereby allowing the paddle 502 to connect or disengage from the two slots.

[0054] Furthermore, an operating rod 508 is fixedly connected to the top of the cylindrical slider 505. By pulling and rotating the cylindrical slider 505, it slides or rotates axially inside the tubular bracket 504, so that the limit block 511 is connected to the first limit groove 506 or the second limit groove 507.

[0055] Furthermore, the bearing seat 503 includes a first bearing 509 and a sleeve 510 , wherein the inner ring of the first bearing 509 is fixedly connected to the coupling rod 501 , and the sleeve 510 is fixedly connected to the outer ring of the first bearing 509 and the bottom of the cylindrical slider 505 .

[0056] The principles of this design are:

[0057] By pulling the operating rod 508, the cylindrical slider 505 is driven to connect the limit block 511 with the first limit groove 506. At this time, the cylindrical slider 505 drives the bearing seat 503 and the coupling rod 501 to rise, and they are no longer in contact with the screw slide 4. At this time, the clutch 5 is in a disengaged state, and the two screw slides 4 work independently.

[0058] By pulling and rotating the operating rod 505, the limit block 511 moves to the lowest point of the second limit groove 507, and the cylindrical slider 505 drives the bearing seat 503 and the coupling rod 501 to fall. The paddles 502 at both ends of the coupling rod 501 are inserted into the slots of the screw rods 402 on both sides. At this time, the clutch 5 is in the engaged state, the two screw rods 402 and the coupling rod 501 are connected into a long rod, and the two screw slides 4 work at the same time.

[0059] Reference Figure 2 The frame 6 includes columns 601 and beams 602. The columns 601 are symmetrically arranged at both ends of the horizontal conveyor belt 1 and are perpendicular to the horizontal conveyor belt 1. Through holes are opened to allow the screw rod 402 to pass through them. The beams 602 symmetrically connect the columns 601 and the tubular bracket 504, and a sliding guide rail 7 is provided in parallel at the bottom thereof.

[0060] The screw slide 4 includes an adjustment handle 401, a screw 402 and a second bearing 403. The adjustment handle 401 is fixedly connected to the end face of the large end of the screw 402. The middle section of the screw 402 is threaded, and the large end passes through the column 601. The second bearing 403 has an inner ring fixedly connected to the large end of the screw 402 and an outer ring fixedly connected to the column 601.

[0061] The screw slide also includes a sliding platform 404 connecting the vertical edge baffle and the crossbeam. A through hole is opened on the upper part of the sliding platform 404, and a thread is provided in the hole to cooperate with the screw 402. The top of the sliding platform 404 and the bottom of the crossbeam 602 are movably connected through a sliding guide rail 7.

[0062] The principle of this design is: when the clutch 5 is in the engaged state, the adjustment handle 401 on either side can be used to make the symmetrically arranged vertical edge sliding platforms 404 move simultaneously in the same or opposite directions to adapt to the production of gypsum boards of different widths. When the clutch 5 is in the disengaged state, the position of the sliding platform 404 on one side can be adjusted individually by adjusting the handle 401.

[0063] Furthermore, a detachable vertical baffle 9 is provided at the bottom of the sliding platform 404 . The vertical baffle includes a vertical baffle 901 and a horizontal baffle 902 . The two baffles are vertically fixed.

The scope of protection 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 spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the embodiments of the present invention.
