AI Technical Summary
Existing gypsum board edging equipment is prone to warping and detachment during the edging process, and the cutting action of the edging adhesive can easily scratch the gypsum board, resulting in poor aesthetics and a high defect rate.
An edge-wrapping device was designed. A second edge-wrapping roller bends the tape on both sides, and a third edge-wrapping roller presses the bent tape onto the board surface. The first and second pressure roller assemblies are combined with a differential speed setting to prevent the tape from being directly folded and adhered to the board surface, thus preventing wrinkles and warping. At the same time, the differential speed setting of the first and second pressure roller assemblies prevents the accidental cutting of adjacent boards during the cutting process.
It effectively prevents the tape from lifting and falling off, improves the appearance of gypsum board, reduces the defect rate, and ensures the production quality of gypsum board.

DETAILED DESCRIPTION
[0018] In order to enable persons skilled in the art to better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor should fall within the protection scope of the present application.
[0019] According to the embodiment of the present application, a binding device is provided, please refer to Figures 1 to 8, including: a feeding device 4 for conveying a single sheet of board accumulated on the feeding device 4 to the first edge covering device 2, the feeding device 4 including a chain 41 for providing forward power to the board and a baffle 42 for blocking the forward movement of the board, the extension direction of the baffle 42 being perpendicular to the transmission direction of the chain 41, the baffle 42 including a passing surface 421, and a first height being provided between the passing surface 421 and the chain 41, the first height being greater than or equal to the thickness of the single sheet of board. Through the above arrangement, it is ensured that only one sheet of board passes through the baffle 42 into the board separating device each time, and the smooth progress of the board separating is ensured.
[0020] In some embodiments, the first height h is about 1-1.99 times the thickness of the board, and the first height h can be adjusted according to the specifications of the board.
[0021] In the edge covering equipment of the present embodiment, referring to Figure 3 , the edge covering equipment includes: a first conveying device 1 for conveying the board; and first edge covering devices 2 respectively arranged on both sides of the first conveying device 1, the first edge covering devices 2 including, in sequence along the conveying direction of the board: first edge covering rollers 21 provided with first abutting surfaces 211 abutting against the side surface of the board, the first abutting surfaces 211 being capable of rolling the adhesive tape onto the side edge of the board; second edge covering rollers 22 provided with adhesive tape folding grooves 221 for folding the two sides of the adhesive tape rolled onto the side edge of the board towards the board; and third edge covering rollers 23 provided with edge covering grooves 231 for adhering the two sides of the adhesive tape folded towards the board to the board surface. Through the above arrangement, the first edge covering rollers 21 can roll the adhesive tape onto the side edge of the board, the second edge covering rollers 22 can fold the two sides of the adhesive tape on the side edge of the board towards the board, and the third edge covering rollers 23 can press the folded adhesive tape onto the board surface, avoiding the direct folding and adhering of the adhesive tape to the board surface, which can prevent the adhesive tape from being wrinkled and prevent the problems of the adhesive tape being raised and falling off.
[0022] In the edge covering equipment of the present embodiment, referring to Figure 3 , the first conveying device includes first and second compression roller assemblies 11 and 12 respectively arranged at the inlet and outlet positions of the first edge covering device 2, wherein the first and second compression roller assemblies 11 and 12 are both power rollers capable of driving the board to move forward, and the conveying speed of the second compression roller assembly 12 is greater than that of the first compression roller assembly 11.
[0023] Through the arrangement of the first and second compression roller assemblies 11 and 12, forward power can be provided for the board entering the first edge covering device 2, so that the whole board gradually adheres to the adhesive tape during the forward movement and gradually leaves the first edge covering device 2, thereby completing the edge covering of the whole board.
[0024] Specifically, the edge-binding equipment also includes a pressure roller motor 13, and a first sprocket 14 and a second sprocket 15 are connected to the output shaft of the pressure roller motor. The first sprocket 14 and the second sprocket 15 are connected to the first pressure roller assembly 11 and the second pressure roller assembly 12 respectively via chains.
[0025] Specifically, the diameter of the first pressure roller assembly 11 is smaller than that of the second pressure roller assembly 12, and the distance between the first pressure roller assembly 11 and the second pressure roller assembly 12 is smaller than the width of the board. Therefore, the linear velocity of the pressure roller of the second pressure roller assembly 12 is greater than that of the first pressure roller assembly 11. When the board inside the first pressure roller assembly 11 comes into contact with the second pressure roller assembly 12, since the transmission speed of the second pressure roller assembly 12 is greater than that of the first pressure roller assembly 11, the second pressure roller assembly 12 drives the board to accelerate forward, thereby creating a gap with the board behind it in the transmission direction, avoiding accidental cutting of adjacent boards when cutting the tape, which would affect the aesthetics of the board.
[0026] Specifically, a third sprocket 16 connected to the second conveying device 20 is coaxially mounted on the rotating shaft of the first pressure roller assembly 11. The sprocket drive enables the speed difference between the first pressure roller assembly 11 and the second conveying device 20, so that the conveying speed of the sheet material of the second conveying device 20 is greater than that of the first pressure roller assembly 11. This ensures that there is no gap between adjacent sheets before the sheet material enters the first pressure roller assembly 11, thus avoiding waste of tape during edge wrapping.
[0027] In addition, a device coaxially mounted on the rotating shaft of the second pressure roller assembly 12 is connected to the third conveying device 30. The fourth sprocket 17, through multi-stage transmission, realizes the speed difference between the second pressure roller assembly 12 and the third conveying device 30, so that the plate conveying speed of the third conveying device 30 is greater than that of the second pressure roller assembly 12, thereby enabling the third conveying device 30 to obtain acceleration and have the inertia to reach the first reversing device 6.

[0034] In the edge covering device of the embodiment, referring to Figure 3The first edge covering device 2 comprises a cutter 28 connected with the output shaft of the motor, the cutter 28 is rotatably arranged between the edge roll 26 and the second roll assembly 12, and the cutter 28 is used to cut off the adhesive tape on the plate after the edge covering is completed.
