[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] See also Figures 1 to 4 A carton dispensing machine includes a working frame 1, an inner wall of the working frame 1 is fixedly connected to an electric push rod 2, the telescopic end of the electric push rod 2 is fixedly connected to a movable block 3, and the movable block 3 is moved left and right by the push of the electric push rod 2.

[0023] A slide groove 11 is provided on the inner bottom wall of the work frame 1, and a slider 12 is slidably connected inside the slide groove 11, and the top of the slider 12 is fixedly connected to the movable block 3. Through the slide groove 11 and the slider 12, the running position of the movable block 3 can be fixed to prevent the movable block 3 from flipping and shifting sideways.

[0024] The movable block 3 is internally slidably connected to the movable rod 4, the inner top wall of the movable block 3 is fixedly connected to the second telescopic spring 13, and the bottom of the second telescopic spring 13 is fixedly connected to the movable rod 4. The second telescopic spring 13 provides downward pressure on the movable rod 4, so that the glue gun 5 can better contact with the cardboard.

[0025] A movable groove is provided on the surface of the working frame 1, and the movable rod 4 is slidably connected to the movable groove. The bottom surface of the movable rod 4 is rotatably connected to two rollers 17 through bearings, and the rollers 17 roll on the surface of the working frame 1. Through the rollers 17, the friction between the movable rod 4 and the horizontal groove of the working frame 1 can be reduced, and the friction between the movable rod 4 and the inclined block 9 can be reduced, which can make the movable rod 4 easier.

[0026] The front end of the movable rod 4 is slidably connected to the glue gun 5, which is driven to rise and fall by sliding the movable rod 4 inside the movable block 3. The outer surface of the glue inlet pipe of the glue gun 5 is slidably connected to two clips 15, and the two clips 15 are fixedly connected to the working frame 1 and the movable block 3 respectively. The glue inlet pipe of the glue gun 5 can be fixed by the clips 15 to prevent the glue inlet pipe from getting stuck inside the device when the movable block 3 moves left and right, causing gluing failure.

[0027] The upper surface of the movable rod 4 is rotatably connected to a gear 16 through a fixed plate, and the gear 16 engages with the glue gun 5 through the teeth on the outer surface of the glue gun 5. By rotating the gear 16, the height of the glue gun 5 can be adjusted, so that the device can glue cardboards of different thicknesses.

[0028] The bottom of the glue gun 5 is fixedly connected to a first telescopic spring 6, and the bottom of the first telescopic spring 6 is fixedly connected to a movable plug 7. The movable plug 7 is pushed by the first telescopic spring 6 to close the glue gun 5. The inside of the movable plug 7 is connected to a ball 8 in a rolling manner, and the bottom end of the ball 8 passes through the glue gun 5 and is slidably connected to the glue gun 5.

[0029] The ball 8 rolls on the surface of the cardboard to lift the movable plug 7, so that the glue inside the glue gun 5 is hit on the cardboard. An inclined block 9 is provided inside the working frame 1, and the movable rod 4 can be raised by the inclined block 9. The vertical surface of the inclined block 9 is fixedly connected to the limiter 14.

[0030] The limiter 14 includes a fixed plate, a telescopic spring and a clamping rod. The fixed plate is fixedly connected to the inclined block 9. The upper surface of the fixed plate is fixedly connected to the telescopic spring. The middle of the fixed plate is slidably connected to the clamping rod. The top end of the clamping rod is fixedly connected to the telescopic spring, and the bottom end of the clamping rod is clamped with the clamping groove opened on the upper surface of the guide rail 10.

[0031] The bottom end of the limiter 14 is engaged with the slot provided on the upper surface of the guide rail 10. The limiter 14 can fix the inclined block 9 on the guide rail 10 to prevent the inclined block 9 from sliding. The bottom surface of the inclined block 9 is slidably connected to the guide rail 10, and the bottom surface of the guide rail 10 is fixedly connected to the inner bottom wall of the workbench 1. The inclined block 9 can be fixed through the guide rail 10.

[0032] Working principle: When in use, first adjust the position of the inclined block 9 to control the gluing length, and use the device to transfer the cardboard to be glued to the bottom of the glue gun 5. Use the gear 16 to adjust the glue gun 5 to a suitable height. Use the electric push rod 2 to push the movable block 3. Under the downward push of the second telescopic spring 13, the roller 17 at the bottom of the movable rod 4 moves horizontally along the surface of the working frame 1. Driven by the movable rod 4, the glue gun 5 moves horizontally on the cardboard surface, and the ball 8 rolls on the cardboard surface, pushing the movable plug 7 upward, so that the movable plug 7 and the movable plug 7 are aligned. The inner bottom wall of the glue gun 5 falls off, and the glue flows out along the outlet at the bottom of the glue gun 5. After running to the specified length, the roller 17 on the bottom of the movable rod 4 contacts the inclined surface of the inclined block 9. Under the continuous push of the electric push rod 2, the inclined block 9 pushes the movable rod 4 to run upward. At the same time, the first telescopic spring 6 presses the movable plug 7 downward, so that the bottom surface of the movable plug 7 contacts the inner bottom wall of the glue gun 5. The glue gun 5 is closed, so that the glue cannot flow out, which reduces the probability of residual glue on the edge of the cardboard, reduces the production of defective products, and improves the finished product rate of the paper box.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
