[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 A door frame surface gluing device includes a base 1, two vertical plates 2 are fixedly connected to the upper end of the base 1, two conveying rollers 3 are rotatably connected between the side walls of the two vertical plates 2 through two rotating shafts, and a door frame body 5 is arranged between the two conveying rollers 3.

[0023] One end of the two rotating shafts on the same side passes through one of the side walls of the vertical plates 2 and is fixedly connected to two gears 4 respectively. The two gears 4 are meshed with each other. A second motor 20 is fixedly connected to the side wall of one of the vertical plates 2 through a bracket, and the movable end of the second motor 20 is fixedly connected to one end of one of the rotating shafts.

[0024] The gluing mechanism includes two sliding rods 6 fixedly connected between the two vertical plates 2, and a sliding block 7 is slidably connected between the side walls of the two sliding rods 6. The side wall of one of the vertical plates 2 is fixedly connected with the first plate 8 and the third plate 10, and the side wall of the other vertical plate 2 is connected with the second plate 9 and the fourth plate 11 through a moving mechanism. Two gluing heads 12 are provided on the lower surfaces of the sliding block 7, the first plate 8 and the second plate 9, and the gluing head 12 is connected to an external glue pump through a glue delivery pipe.

[0025] The angle between the two glue coating heads 12 on the slide block 7 and the door frame body 5 is 0°, and the angle between the two glue coating heads 12 on the first plate 8 and the second plate 9 and the door frame body 5 is 90°.

[0026] Further, such as Figure 2 As shown, when applying glue on the door frame body 5, first, the two glue heads 12 on the slider 7 apply two lines of glue on the upper surface of the end of the door frame body 5, and then during the movement of the door frame body 5, the two glue heads 12 on the first plate 8 and the second plate 9 apply four lines of glue on the upper surface of the door frame body 5, and when the door frame body 5 is about to be output, the two glue heads 12 on the slider 7 apply two lines of glue again on the upper surface of the end of the door frame body 5, so that the glue on the door frame body 5 is respectively in two rectangular shapes. This method not only has good uniformity, but also reduces the amount of glue by reducing the adhesion between the door frame and the door panel, avoiding the prior art that the gluing method is mostly manual through a roller brush, which is prone to uneven glue coating and a large amount of glue coating.

[0027] A first motor 13 is fixedly connected to the side wall of one of the vertical plates 2 , a first lead screw 14 is fixedly connected to the movable end of the first motor 13 , and a side wall of the first lead screw 14 is threadedly connected to a side wall of the slider 7 .

[0028] The moving mechanism includes an L-shaped plate 15 fixedly connected to the side wall of one of the vertical plates 2, the side wall of the L-shaped plate 15 is rotatably connected to a second screw 16, the side wall of the second screw 16 is threadedly connected to a moving plate 17, and the side wall of the moving plate 17 is fixedly connected to two moving rods 18, one of the moving rods 18 is fixedly connected to the side wall of the second plate 9, and the other moving rod 18 is fixedly connected to the side wall of the fourth plate 11.

[0029] Furthermore, by rotating the second screw 16, the movable plate 17 can drive the second plate 9 and the fourth plate 11 to move through the two movable rods 18, thereby adjusting the distance between the first plate 8 and the second plate 9, and adjusting the distance between the third plate 10 and the fourth plate 11, thereby delivering glue to the door frame bodies 5 of different widths.

[0030] The second screw 16 is fixedly connected to a handwheel on the side wall away from the vertical plate 2. The side wall of the second screw 16 located between the L-shaped plate 15 and the handwheel is threaded. The threaded side wall is connected to a nut 19, and the side wall of the nut 19 is tightly fitted with the side wall of the L-shaped plate 15.

[0031] When conveying glue to the door frame body 5, firstly, the nut 19 is rotated to separate from the side wall of the L-shaped plate 15, and then the second screw 16 is rotated clockwise or counterclockwise, and then the movable plate 17 can drive the second plate 9 and the fourth plate 11 to move toward the second screw 16 or away from the second screw 16 through the two movable rods 18, and the spacing between the first plate 8 and the second plate 9 is adjusted, and the spacing between the third plate 10 and the fourth plate 11 is adjusted to ensure that the door frame body 5 can be conveyed stably;

[0032] After the positions of the second plate 9 and the fourth plate 11 are adjusted, the rotating nut 19 is tightly fitted with the side wall of the L-shaped plate 15 to inhibit the rotation of the second lead screw 16, thereby ensuring the position stability of the second plate 9 and the fourth plate 11;

[0033] Then, the door frame body 5 is placed between the two conveying rollers 3, and the second motor 20 is started to rotate clockwise, so that the two conveying rollers 3 can convey the door frame body 5;

[0034] During the transportation of the door frame body 5, the external glue will be transported to the glue coating head 12 through the glue delivery pipe and the external glue delivery pump, and its transportation method is the existing technology. Then the first motor 13 is driven to intermittently rotate forward and reverse, so that the first screw 14 drives the slider 7 to slide back and forth, and then the two glue coating heads 12 on the slider 7 apply two layers of glue on the upper surface of the end of the door frame body 5. Then, during the movement of the door frame body 5, the two glue coating heads 12 on the first plate 8 and the second plate 9 apply four layers of glue on the upper surface of the door frame body 5, and when the door frame body 5 is about to be output, the two glue coating heads 12 on the slider 7 apply two layers of glue again on the upper surface of the end of the door frame body 5, so that the glue on the door frame body 5 is respectively in two rectangular shapes. This method not only has good uniformity, but also reduces the amount of glue while reducing the adhesion between the door frame and the door panel, avoiding the prior art that the gluing method is mostly manual through a roller brush, which is prone to uneven glue coating and a large amount of glue coating.
