Description

Technical Field

[0002] Automatic glue dispensing machine is a professional equipment that replaces manual glue dispensing, and has a wide impact in the industry. Traditional glue dispensing is achieved by manual operation of workers. Glue dispensing technology is more and more common in industrial production, and the requirements are becoming more and more stringent. With the rapid development of automation technology, manual glue dispensing can no longer meet the needs of industry.

[0003] For example, the automatic glue dispensing and sealing equipment for packaging boxes with the authorization announcement number "CN219325985U" transports packaging boxes by clamping, which reduces the displacement of packaging boxes due to the jumping of packaging boxes when feeding into the packaging box track, and speeds up the feeding speed. The adjustable discharging conveyor belt transports packaging boxes by clamping, which reduces the displacement of packaging boxes due to the jumping of packaging boxes when feeding into the discharging conveyor belt, and speeds up the discharging speed. However, the automatic glue dispensing and sealing equipment for packaging boxes requires the operator to manually rotate multiple worms to adjust the distance of the feeding conveyor belt each time the glue dispensing and sealing operation is performed on the packaging box, which consumes a lot of the operator's time, thereby reducing work efficiency. At the same time, the automatic glue dispensing and sealing equipment for packaging boxes uses a U-shaped clamp to seal the packaging box, and the size of the U-shaped clamp cannot be adjusted, resulting in that only boxes of fixed sizes can be sealed, which limits the work.

[0029] Working principle:

[0030] When the packaging box is automatically sealed by dispensing glue.

[0031] Preparation:

[0032] First, place the packaging box that needs glue dispensing in the middle of the second bent plate 11.

[0033] Limiting process:

[0034] First, the power supply of the first motor 902 is turned on. When the output shaft of the first motor 902 rotates forward, the first worm 903 rotates, the first worm 903 rotates, the first worm wheel 904 rotates, the first worm wheel 904 rotates, the gear 905 rotates, and the rack 907 moves rightward. The rack 907 moves rightward and drives the first concave plate 908 to move rightward. (For example, Figure 5 ), when the output shaft of the first motor 902 is reversed, the rack 907 moves to the left, driving the first concave plate 908 to move to the left, and the concave plate 908 moves left and right, driving the second bent plate 11 to move left and right, thereby driving the first conveyor belt 10 to move. When the two first conveyor belts 10 move to a suitable distance, the first motor power supply 902 is turned off to realize automatic limiting of the packaging box. There is no need for the staff to manually adjust the position of the threaded rod, thereby improving work efficiency.

[0035] Adjustment process:

[0036] First, the power supply of the second motor 402 is turned on, and the output shaft of the second motor 402 rotates forward to drive the second worm 403 to rotate, and the rotation of the second worm 403 drives the worm wheel 404 to rotate, and the rotation of the worm wheel 404 drives the first cross bar 408 to rotate, and the rotation of the first cross bar 408 drives the first rotating rod 405 to rotate, and the rotation of the first rotating rod 405 drives the slider 406 to move downward, and the downward movement of the slider 406 drives the second rotating rod 407 to move rightward, and the second rotating rod 407 moves rightward to drive the fixing block 409 to move rightward, and the fixing block 409 moves rightward to drive the second concave plate 410 to move rightward, thereby driving the push rod 412 to move rightward. When the first rotating rod 405 is horizontal, the push rod 412 moves to the right to the maximum distance (such as Figure 4 ), when the push rod 412 moves to the right to the maximum distance, the first rotating rod 405 continues to rotate and the push rod 412 moves to the left. When the first rotating rod 405 rotates 180°, the push rod 412 moves to the left to the maximum distance. The push rod 412 moves left and right to drive the vertical plate 7 to move left and right. When the vertical plate 7 moves to a suitable position, the power supply of the second motor 402 is turned off to adjust the distance between the vertical plates 7. Paper boxes of different sizes can be sealed, avoiding work limitations.

[0037] Glue dispensing and sealing process:

[0038] The movement of the first conveyor belt 10 and the second conveyor belt 2 is controlled by the control system. The box covers on both sides of the packaging box are carried on the first conveyor belt 10, driving the packaging box to move along the paths of the two first conveyor belts 10. When the packaging box reaches the first sensor 13, the first sensor 13, the control system and the second sensor 14 have been disclosed in the authorization announcement number "CN219325985U", and the working principle is the same. The first sensor 13 is electrically connected to the control system to control the glue spray barrel 12 to spray glue. When the first sensor 13 senses that an object has passed, it transmits a signal to the control system to control the glue spray barrels 12 on both sides. Glue is sprayed on the packaging box. When the first sensor 13 does not sense an object, a stop signal is sent to the control system, and the glue barrel 12 stops spraying glue. The first conveyor belt 10 drives the packaging box to the second conveyor belt 2, and the second conveyor belt 2 drives the packaging box to continue to move. When the packaging box reaches the second sensor 14, the second sensor 14 is connected to the control system to control the operation of the first conveyor belt 10 and the second conveyor belt 2. When the second sensor 14 senses something, it transmits a stop signal to the control system to stop the first conveyor belt and the second conveyor belt, and starts the switch of the hydraulic cylinder 6 to control The output end of the hydraulic cylinder 6 extends out to drive the straight plate 5 to move downward, and the downward movement of the straight plate 5 drives the adjusting device 4 to move downward, thereby driving the two vertical plates 7 to move downward. When the vertical plates 7 move downward, the box covers on both sides of the packaging box will fit tightly against the box, and the box will be sealed by glue. The output end of the hydraulic cylinder 6 is controlled to move back to drive the vertical plates 7 to move upward, and the packaging box that has been sealed with glue is taken out. When the second sensor 14 does not sense an object, it transmits the transmission to the control system to allow the first conveyor belt 11 and the second conveyor belt 2 to continue to operate. After the work is completed, the hydraulic cylinder 6 is closed to realize automatic glue sealing of the packaging box.
