[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0019] Example 1

[0020] See Figures 1 to 3As shown, the adhesive application mechanism involved in this embodiment includes a fixed plate 1 arranged at the rear and a movable plate 2 arranged at the front. The movable plate 2 moves left and right relative to the fixed plate 1. A first linear guide rail 3 extending left and right is fixedly connected to the movable plate 2. A left slider 4 and a right slider 5 are slidably connected to the first linear guide rail 3. A left adhesive application unit 100 is provided on the left slider 4, and a right adhesive application unit 200 is provided on the right slider 5. A composite screw parallel to the first linear guide rail is rotatably connected to the movable plate 2. One end of the composite screw is driven by a first motor 6 that controls its rotation. The first motor 6 is located on the movable plate. The composite screw includes a first screw 7 and a second screw 8 arranged coaxially and with opposite helical directions. A first screw nut 9 is threadedly connected to the first screw 7 and is connected to the left adhesive application unit. A second screw nut 10 is threadedly connected to the second screw 8 and is connected to the right adhesive application unit.

[0021] Furthermore, both the left coating unit 100 and the right coating unit 200 include a coating cylinder 11. The bottom of the coating cylinder 11 is provided with a glue injection nozzle 12 and the top is provided with a cover plate 13. A pusher shaft 14 is rotatably connected to the cover plate 13. One end of the pusher shaft 14 is provided with a pusher propeller blade 15 located inside the coating cylinder, and the other end is drivenly connected to a second motor 16 for controlling rotation. The second motor 16 is located on the cover plate 13. The side of the coating cylinder 11 is provided with a filling port 17, which is arranged close to the cover plate. A filling hopper 18 is connected to the filling port 17.

[0022] Furthermore, a linear reciprocating motion mechanism is provided between the fixed plate 1 and the movable plate 2 to control the movable plate to move left and right relative to the fixed plate. The linear reciprocating motion mechanism includes a turntable 19 rotatably connected to the fixed plate. A third motor (not shown) is drivenly connected to the turntable 19 to control its rotation. The third motor is located on the fixed plate 1. A first pin 20 is eccentrically arranged on the turntable 19 and kept parallel to its axis. A second pin 21 is provided on the movable plate 2 and kept parallel to the axis of the first pin. A connecting rod 22 is provided between the second pin 21 and the first pin 20, with one end hinged to the first pin and the other end hinged to the second pin.

[0023] Furthermore, the fixed plate 1 is provided with a second linear guide rail 23 extending to the left and right, and a second linear slider 24 is slidably connected to the second linear guide rail 23. The movable plate 2 is disposed on the second linear slider 24.

[0024] In this embodiment, by operating the third motor, the turntable 19 rotates. Under the transmission action of the first pin 20, the second pin 21 and the connecting rod 22, the movable plate 2 moves back and forth relative to the fixed plate 1. At the same time, the second motor 16 also operates, driving the pusher shaft 14 and its pusher propeller blade 15 to rotate, pushing the glue contained in the glue coating cylinder 11 downwards, so that it is discharged from the glue injection nozzle 12, thereby performing the glue coating operation.

[0025] The spacing between the left adhesive application unit 100 and the right adhesive application unit 200, which are arranged at two intervals, can be adjusted as follows:

[0026] a. Reduce the distance between the left glue application unit 100 and the right glue application unit 200: Operate the first motor 6 to drive the composite screw to rotate clockwise, the first screw nut 9 on the first screw 7 moves to the right, and the second screw nut 10 on the second screw 8 moves to the left, causing the left glue application unit 100 and the right glue application unit 200 to move in opposite directions.

[0027] b. Increase the distance between the left glue application unit 100 and the right glue application unit 200: Operate the first motor 6 to drive the composite screw to rotate counterclockwise, the first screw nut 9 on the first screw 7 moves to the left and the second screw nut 10 on the second screw 8 moves to the right, causing the left glue application unit 100 and the right glue application unit 200 to move relative to each other.

[0028] The filling port 17 is used to add glue to the inside of the glue applicator 11.

[0029] The second linear guide rail 23, in conjunction with the second linear slider 24, serves as a sliding guide for the movable plate 2 to move left and right relative to the fixed plate 1.

[0030] The adhesive applicator involved in this utility model drives the movable plate to move left and right relative to the fixed plate through a linear reciprocating motion mechanism, so as to continuously change the adhesive application position, increase the adhesive application width, and improve the subsequent bonding effect. It also drives the composite screw to rotate through a motor, which can change the distance between the two screw nuts, thereby adjusting the distance between the two glue nozzles, so as to achieve the effect of applying adhesive to materials with different widths. It has strong adaptability, complete overall functions, and strong practicality.
