Technical Field

[0001] This utility model relates to the field of environmentally friendly cardboard box production technology, specifically to an automatic coating machine for biodegradable adhesives for environmentally friendly cardboard boxes. Background Technology

[0002] In the production of environmentally friendly cardboard boxes, biodegradable adhesives are used to coat various parts of the box for bonding and assembly. Existing adhesive coating machines typically employ an open glue tank structure. During coating, as the adhesive is consumed, the liquid level in the tank gradually decreases, requiring operators to frequently replenish the adhesive to maintain consistent coating results. This manual adhesive replenishment not only increases labor intensity but also easily leads to uneven coating thickness due to untimely replenishment, affecting the quality of the cardboard box. Utility Model Content

[0003] In view of the problems existing in the above-mentioned automatic coating machine for biodegradable adhesives for environmentally friendly cardboard boxes, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide an automatic coating machine for biodegradable adhesives for environmentally friendly cardboard boxes, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic coating machine for biodegradable adhesives for environmentally friendly cardboard boxes includes an adhesive shell and a coating roller. The coating roller is disposed inside the upper side of the adhesive shell. A first rotating rod is fixedly sleeved in the middle of the coating roller. Both ends of the first rotating rod are rotatably connected to the inner wall of the corresponding adhesive shell. A first motor is fixedly disposed on one outer wall of the adhesive shell. The output end of the first motor is fixedly connected to one end of the first rotating rod. A limiting roller is disposed parallel above the coating roller. Vertical plates are fixedly disposed on the upper surface of the adhesive shell on both sides of the limiting roller. An adjustment mechanism for moving the limiting roller is disposed on the inner side of the two vertical plates. A piston plate is slidably abutted inside the adhesive shell. L-shaped plates are fixedly disposed on both ends of one side of the upper surface of the piston plate. The upper end of the L-shaped plate extends to the top of the adhesive shell. A transmission mechanism for moving the L-shaped plate is disposed on the outer wall of the adhesive shell near the L-shaped plate.

[0007] Preferably, the adjusting mechanism includes a slider and a threaded rod. The side wall of the vertical plate has a strip-shaped opening, and the slider is slidably disposed inside the strip-shaped opening. A second rotating rod is fixedly sleeved in the middle of the limiting roller. The two ends of the second rotating rod are rotatably connected to the corresponding sliders. The threaded rod is vertically rotatably disposed inside the strip-shaped opening, and one side of the slider is threadedly sleeved with the threaded rod.

[0008] Preferably, the transmission mechanism includes an internally threaded tube and a lead screw. A first side plate is fixedly installed on the lower outer wall of the glue shell near the L-shaped plate. The internally threaded tube is rotatably installed on the upper surface of the first side plate. The lead screw is threaded into the inside of the internally threaded tube. The upper end of the lead screw is fixedly connected to the corresponding L-shaped plate. A second motor is fixedly installed on the lower side of the first side plate. The output end of the second motor is fixedly connected to one end of the lead screw.

[0009] Preferably, a second side plate is fixedly provided on the outer wall of the glue shell and on one side of the first side plate.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. In this utility model, the internal threaded tube is driven to rotate by a second motor. The internal threaded tube drives the non-rotating threaded rod to move, which in turn drives the L-shaped plate to move. The L-shaped plate then drives the piston plate to move inside the glue shell, pushing the glue inside the glue shell upward and maintaining a stable glue level. This ensures that the glue-applying roller is in stable contact with the glue, thus guaranteeing the glue-applying quality.

[0014] 2. In this utility model, by rotating the threaded rod, the threaded rod drives the slider to move, which in turn drives the limiting roller to move. This allows for adjustment of the height of the limiting roller, making it convenient to limit the position of cartons at different rear ends. Attached Figure Description

[0022] This utility model discloses an automatic coating machine for biodegradable adhesives for environmentally friendly cardboard boxes.

[0023] Reference Figure 1-3 An automatic coating machine for biodegradable adhesives on environmentally friendly cardboard boxes includes an adhesive shell 1 and a coating roller 2. The coating roller 2 is disposed inside the upper side of the adhesive shell 1. A first rotating rod 3 is fixedly sleeved in the middle of the coating roller 2. Both ends of the first rotating rod 3 are rotatably connected to the inner wall of the corresponding adhesive shell 1. A first motor 6 is fixedly disposed on one outer wall of the adhesive shell 1. The output end of the first motor 6 is fixedly connected to one end of the first rotating rod 3. A limit roller 4 is disposed parallel above the coating roller 2. The upper surface of the adhesive shell 1 and located on both sides of the limit roller 4... Vertical plates 7 are fixedly installed on both sides. An adjustment mechanism for moving the limiting roller 4 is provided on the inner side of the two vertical plates 7. A piston plate 9 is slidably abutted inside the glue shell 1. A sealing ring is fixedly sleeved on the outer wall of the piston plate 9 to improve the sealing between the piston plate 9 and the inner wall of the glue shell 1. L-shaped plates 10 are fixedly installed at both ends on one side of the upper surface of the piston plate 9. The upper end of the L-shaped plate 10 extends to the top of the glue shell 1. A transmission mechanism for moving the L-shaped plate 10 is provided on the outer wall of the glue shell 1 on the side close to the L-shaped plate 10.

[0024] Reference Figure 1-3 The adjusting mechanism includes a slider 8 and a threaded rod 15. A strip-shaped opening is provided on the side wall of the vertical plate 7. The slider 8 is slidably arranged inside the strip-shaped opening. A second rotating rod 5 is fixedly sleeved in the middle of the limiting roller 4. The two ends of the second rotating rod 5 are respectively rotatably connected to the corresponding slider 8. The threaded rod 15 is vertically rotatably arranged inside the strip-shaped opening. One side of the slider 8 is threadedly sleeved with the threaded rod 15. A sliding rod 18 is arranged parallel to one side of the threaded rod 15. Both ends of the sliding rod 18 are fixedly connected to the corresponding strip-shaped opening. One side of the slider 8 is movably sleeved with the sliding rod 18, so that the slider 8 can slide stably.

[0025] Reference Figure 1-3 The transmission mechanism includes an internally threaded tube 14 and a lead screw 17. A first side plate 13 is fixedly installed on the lower outer wall of the glue shell 1 near the L-shaped plate 10. The internally threaded tube 14 is rotatably installed on the upper surface of the first side plate 13. The lead screw 17 is threaded into the inside of the internally threaded tube 14. The upper end of the lead screw 17 is fixedly connected to the corresponding L-shaped plate 10. A second motor 16 is fixedly installed on the lower side of the first side plate 13. The output end of the second motor 16 is fixedly connected to one end of the lead screw 17. A second side plate 19 is fixedly installed on the outer wall of the glue shell 1 and on one side of the first side plate 13. A fixed tube 11 is fixedly installed on the upper surface of the second side plate 19. A movable rod 12 is movably sleeved inside the fixed tube 11. The upper end of the movable rod 12 is fixedly connected to the corresponding L-shaped plate 10, so that the piston plate 9 can slide stably.

[0026] In this utility model, when in use, the height of the limiting roller 4 is first adjusted according to the thickness of the carton to be coated. The operator rotates the threaded rod 15. Since the slider 8 is threadedly connected to the threaded rod 15 and movably connected to the slide rod 18, when the threaded rod 15 rotates, it drives the slider 8 to move up and down along the strip opening, thereby driving the limiting roller 4 to move up and down to the appropriate position, ensuring that the carton can pass smoothly between the coating roller 2 and the limiting roller 4 and obtain a uniform coating effect.

[0027] Next, the first motor 6 is started, and the first motor 6 drives the first rotating rod 3 to rotate, which in turn drives the glue coating roller 2 to rotate. At this time, the biodegradable adhesive is stored in the glue shell 1, the piston plate 9 is located at the bottom of the glue shell 1, and the adhesive is located above the piston plate 9. As the glue coating process proceeds, the adhesive is continuously coated on the carton, and the adhesive liquid level in the glue shell 1 gradually decreases.

[0028] To maintain a stable adhesive level, the second motor 16 is started. The second motor 16 drives the internal threaded tube 14 to rotate. Since the lead screw 17 is threadedly connected to the internal threaded tube 14 and the upper end of the lead screw 17 is fixedly connected to the piston plate 9 through the L-shaped plate 10, and the movable rod 12 slides in the fixed tube 11 to play a guiding role, when the internal threaded tube 14 rotates, it drives the lead screw 17 to move upward. The lead screw 17 pushes the piston plate 9 to slide upward in the glue shell 1 through the L-shaped plate 10, thereby squeezing the adhesive upward and keeping the adhesive level at the set height, ensuring that the glue roller 2 can always evenly pick up the adhesive.

[0029] Throughout the coating process, the sealing ring on the outer wall of the piston plate 9 ensures that the adhesive will not leak, improving coating efficiency and quality. When adhesive needs to be replenished, the equipment can be paused, adhesive can be added through the feed port on the glue shell 1, and then the coating operation can continue. In this way, the present invention realizes automatic lifting and stable control of the adhesive level, eliminating the need for operators to frequently replenish adhesive, reducing labor intensity, and improving production efficiency and coating quality.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
