Description

Technical Field

[0001] This utility model relates to the field of feeding mechanisms, and in particular to a feeding mechanism for a fully automatic corrugated paper gluing machine. Background Technology

[0002] Corrugated cardboard is a flat sheet material. To transform it into a three-dimensional box that can hold and protect items, specific seams or overlaps must be securely connected. Gluing is the main way to achieve this connection. Feeding is the first step in the work of the gluing machine and a key prerequisite for ensuring the quality and efficiency of subsequent gluing. The die-cut cardboard needs to be accurately and stably fed into the working area of ​​the gluing machine.

[0003] A search revealed Chinese Patent Publication No. CN221851301U, which discloses a feeding mechanism for a fully automatic corrugated cardboard gluing machine. By incorporating a paper-supporting mechanism, the feeding mechanism drives the bottom corrugated cardboard through the bottom surface of the paper-stopping knife and is conveyed by the conveyor belt. Meanwhile, one end of the remaining corrugated cardboard rests against the inclined blade surface of the paper-stopping knife. Due to the inclined structure of the paper-stopping knife, the upper corrugated cardboard extends away from the conveyor belt, while the other end of the corrugated cardboard rests on the roller surface of the paper-supporting roller, reducing friction between the upper and lower corrugated cardboard. This process continues until the bottom corrugated cardboard is fully loaded, at which point the upper corrugated cardboard falls onto the surface of the feeding mechanism under its conveying action to complete the subsequent loading.

[0004] In the above technical solution, the paper-supporting mechanism ensures that the corrugated paper falls accurately onto the surface of the feeding mechanism for feeding. However, the feeding mechanism lacks a guiding function, and the lack of lateral constraint on the cardboard can cause it to deviate or tilt, resulting in errors in the feeding position and deviations in the bonding position. At the same time, paper scraps will adhere to the surface of the cardboard after die-cutting, which reduces the effectiveness of subsequent box gluing operations and lowers production quality. Therefore, a fully automatic corrugated paper gluing machine feeding mechanism is proposed to solve the above problems. Utility Model Content

Each set of drive plates 9... Four support plates 10 are provided on the upper part, and are located in pairs on the upper and lower sides of the drive plate 9. The pairs of support plates 10 are connected to the mounting frame 11 through two sets of slide blocks 13. The outer wall of the support plate 10 is provided with the mounting frame 11, which is arranged in a U-shape. The side wall of the mounting frame 11 is provided with a slide groove 12. The inner wall of the slide groove 12 is slidably connected to the slide block 13. The outer wall of the slide block 13 is adapted to the inner wall of the slide groove 12. The inner wall of the slide groove 12 is fixedly connected to the slide rod 14. The outer wall of the slide 14 is slidably connected to the inner wall of the slide block 13. The side wall of the slide block 13 is fixedly connected to the spring 15. The spring 15 is sleeved on the outer wall of the slide rod 14. The two ends of the spring 15 are fixedly connected to the opposite side of the two sets of slide blocks 13. The inner surface of the mounting frame 11 is rotatably connected to the guide roller 16. Several guide rollers 16 are provided. The U-shaped mounting frame 11 facilitates the installation of the guide rollers 16. The two sets of guide rollers 16 on both sides of the top of the feeding roller 6 are used to contact the two sides of the carton and guide it.

[0033] Reference Figures 2-4The outer wall of the guide roller 16 is provided with a cleaning assembly, which includes a through hole 17, a support pipe 18, a valve 19, a connecting pipe 20, a collection box 21, a filter screen 22, and an air pump 23. The through holes 17 are formed on the outer wall of the guide roller 16, and several equally spaced through holes 17 are formed on each group of guide rollers 16. The interior of the guide roller 16 is hollow, and the inner wall of the guide roller 16 is rotatably connected to the support pipe 18. The support pipe 18 is connected to the hollow interior of the guide roller 16 and passes through the mounting frame 11. The outer wall of the support pipe 18 is fixedly connected to the connecting pipe 20, and the support pipe 18 and the connecting pipe 20 are connected. The surface of the support pipe 18 is provided with a valve 19, which controls the flow rate of air entering the support pipe 18 through the through hole 17 and is set as a one-way valve. It can only enter the connecting pipe 20 through the support pipe 18. The inner wall of the connecting pipe 20 is fixedly connected to the collection box 21 through the pipe. The collection box 21 is a sealed box and is sealed through the sealing door. The pipe inside the collection box 21 connected to the connecting pipe 20 is partially retractable, so that the airflow can be kept unobstructed when the drive plate 9 moves. The inner wall of the collection box 21 is fixedly connected to the filter screen 22. The filter screen 22 separates the pipe connected to the connecting pipe 20 from the pipe connected to the air pump 23. When the air pump 23 is started, it forms a negative pressure. The paper scraps that the cardboard box avoids can enter the inside of the collection box 21 through the through hole 17 and be blocked by the filter screen 22. Excess air is discharged through the air pump 23. The outer wall of the collection box 21 is fixedly connected to the air pump 23. The input end of the air pump 23 is also connected to the inside of the collection box 21 through the pipe.

[0034] Reference Figure 1 and Figure 5 An inclined plate 24 is fixedly connected to the outer wall of the mounting frame 11. Both sets of mounting frames 11 are equipped with an inclined plate 24, a sensor 25, and a transparent cover 26. The inclined plate 24 is tilted towards the feed inlet. In order to achieve effective distance measurement and meet the requirements of advance detection, a sensor 25 is fixedly connected to the outer wall of the inclined plate 24. The sensor 25 is a miniature laser distance sensor. The data of the sensor 25 is fed back to the PLC in real time, which drives the electric push rod 8 to adjust the position of the guide roller 16 to form a closed-loop control. A transparent cover 26 is fixedly connected to the outer wall of the inclined plate 24. The transparent cover 26 is sleeved on the outer wall of the sensor 25. The transparent cover 26 protects the sensor 25 and provides dust protection without affecting the normal use of the sensor 25.

[0035] Working principle: Motor 2 starts, and its output power is reduced and increased in torque by reducer 3. The output shaft of reducer 3 drives the connected sprocket 4 to rotate. Sprocket 4 drives chain 5, which in turn drives all meshed sprockets 4 to rotate. All feeding rollers 6 are synchronously driven to rotate via their sprockets 4 and chains 5, conveying the corrugated cartons placed on them forward. Sensor 25 continuously or periodically emits distance measurement signals in the feeding direction through transparent cover 26. When it detects an approaching carton, sensor 25 feeds back the distance signal to the equipment's PLC control system in real time. The PLC then... The preset program and control logic calculate the required position of the guide roller 16. The PLC outputs a control signal to drive the electric push rod 8 to extend and retract. The extension and retraction of the electric push rod 8 causes the drive plate 9, which is fixed to its output end, to move. The drive plate 9, through the support plate 10 connected to it, drives the entire mounting frame 11 to move along a specific trajectory. The support plate 10 causes the slide block 13 to slide along the slide rod 14 in the slide groove 12 of the mounting frame 11. At the same time, the springs 15 connecting the two sets of slide blocks 13 are compressed or stretched. The springs 15 provide cushioning and help maintain the contact pressure between the guide roller 16 and the carton. Finally, the guide roller 16 is installed on the mounting frame. Several guide rollers 16 on the feed roller 6 are adjusted to positions suitable for the current width of the carton. The guide rollers 16 located on both sides of the top of the feed roller 6 will contact and guide the sides of the carton to ensure its straight and stable conveying. At the same time, when the carton passes under the guide rollers 16, the air pump 23 is started, generating negative pressure in the collection box 21. The negative pressure is transmitted to the cavity inside the guide roller 16 through the pipe, connecting pipe 20, and support pipe 18. The negative pressure inside the guide roller 16 causes air to be drawn in through the through holes 17 on its outer wall. Paper scraps on the surface of the carton are drawn into the through holes 17 with the airflow and enter the guide roller 16. The airflow carrying paper scraps passes through the support pipe 18, where the valve 19 ensures unidirectional airflow. The airflow then enters the collection box 21 via the connecting pipe 20. Inside the collection box 21, the filter screen 22 intercepts the paper scraps, which either adhere to the surface of the filter screen 22 or fall to the bottom of the box. The filtered air is then discharged through the air pump 23. The sensor 25 continuously monitors the subsequent cartons. Based on the newly detected carton size signal, the PLC drives the electric push rod 8 again to adjust the position of the guide roller 16. At the same time, the air pump 23 continues to work to clean the surface of the carton, and the feeding roller 6 continuously operates to transport the carton, forming an automated cyclic workflow.
