DETAILED DESCRIPTION

[0021] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, a glue discharging device provided by an embodiment of the utility model includes a base 1, a mounting base 11 is fixedly connected to the base 1, a conveyor belt 2 is arranged on the base 1, limit plates 21 are arranged on both sides of the conveyor belt 2, a correction component 23 is arranged on the limit plate 21, a mounting groove 12 is opened on the mounting base 11, a cylinder 13 is fixedly installed inside the mounting groove 12, a connecting base 4 is arranged on the mounting base 11, the connecting base 4 is slidably connected to the mounting groove 12, the connecting base 4 is fixedly connected to the output end of the cylinder 13, a control box 41 is arranged on the connecting base 4, a cantilever 43 is arranged on the control box 41, a slider 44 is arranged on the cantilever 43, a lifting plate 45 is arranged on the slider 44, and a glue discharging component 5 is arranged on the lifting plate 45.

[0023] It should be noted that the control box 41 is internally provided with electrical equipment for controlling the glue discharging device. When in use, the cardboard is transported to the lower end of the glue discharging assembly 5 through the conveyor belt 2, and then the motor is controlled to drive the screw to rotate, so that the slider 44 slides on the cantilever 43, and the lifting plate 45 is adjusted in height on the slider 44, and then the glue is discharged onto the cardboard through the glue discharging assembly 5.

[0024] Specifically, the correction assembly 23 includes a fixing plate 3, the fixing plate 3 is connected to the limiting plate 21 by screws, a damping shaft 31 is connected to the fixing plate 3 by screws, and a guide plate 32 is arranged on the damping shaft 31;

[0025] Specifically, a guide rod 34 is slidably connected inside the damping shaft 31, and the guide rod 34 is fixedly connected to the guide plate 32. A sliding hole 33 is opened on the damping shaft 31, and a spring 35 is arranged in the sliding hole 33. One end of the spring 35 is fixedly connected to the sliding hole 33, and the other end of the spring 35 is fixedly connected to the guide plate 32.

[0026] Furthermore, correction components 23 are installed on the limit plates 21 on both sides of the conveyor belt 2. When the cardboard is conveyed, the tilted cardboard contacts the guide plate 32 and rotates along the edge of the guide plate 32 to complete the guidance. For the cardboard with a large offset, when it contacts the guide plate 32, it will generate a large pressure on the guide plate 32 due to the large tilt angle, and at the same time compress the spring 35 so that the cardboard still fits the guide plate 32. Due to the elastic force of the spring 35, the guard will slowly move to the center position during the movement to achieve the correction of the guard position.

[0027] Specifically, a glue storage tank 42 is fixedly mounted on the control box 41, a pressure pump 51 is arranged on the lifting plate 45, the glue storage tank 42 and the pressure pump 51 are connected by a pipe fitting, a connector 52 is connected to the pipe fitting on the pressure pump 51, and the connector 52 is fixedly connected to the lifting plate 45;

[0028] Specifically, the glue discharging assembly 5 includes a rubber hose 6 , which is fixedly connected to the lifting plate 45 . A connecting pipe 53 is provided between the rubber hose 6 and the connector 52 , and a one-way valve 54 is provided inside the connecting pipe 53 .

[0029] Specifically, a hollow inner cavity 61 is formed inside the rubber hose 6, a limit ring 62 is arranged inside the inner cavity 61, a telescopic rod 63 is arranged at the upper end of the rubber hose 6, a clamping ring 64 is fixedly connected to the inner cavity 61, a sealing ring 65 is fixedly connected to the lower end of the clamping ring 64, the output end of the telescopic rod 63 passes through the clamping ring 64 and the sealing ring 65, a movable plug 66 is fixedly connected to the output end of the telescopic rod 63, a push rod 67 is arranged at the lower end of the movable plug 66, and a rubber head 68 is fixedly connected to the lower end of the rubber hose 6.

[0030] Furthermore, the hose 6 is a hollow tube with openings at both ends. The upper end of the hose 6 is sealed by a telescopic rod 63, and the lower end is sealed by a rubber head 68. The interior of the hose 6 is prevented from contacting the telescopic rod 63 by a clamping ring 64, a sealing ring 65 and a movable plug 66. The limiting ring 62 inside the hose 6 is correspondingly arranged to the push rod 67, so that when the push rod 67 moves downward, it pushes through the limiting ring 62 and contacts the glue inlet of the rubber head 68, thereby preventing glue sediment from accumulating at the rubber head 68 and forming a blockage.

[0031] Working principle: When in use, first adjust the positions of the glue discharging component 5 and the correction component 23. The fixing plate 3 in the correction component 23 is connected to the damping shaft 31 by screws, and the height can be adjusted so that the guide plate 32 can adapt to the height of the cardboard. The cylinder 13 is started by the control box 41 to adjust the height of the mounting seat 11 so that the glue discharging component 5 can adapt to the height of the cardboard.

[0032] When the cardboard is conveyed to the lower end of the glue outlet assembly 5, the pressure pump 51 extracts glue from the glue storage tank 42, conveys it to the connector 52 through the pipe fitting, and enters the glue hose 6 through the one-way valve 54 in the connecting pipe 53. The telescopic rod 63 is started to push the movable plug 66 to move downward. The movable plug 66 moves downward and drives the push rod 67 to move, so that the glue is evenly squeezed onto the cardboard through the glue head 68.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
