Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology, and in particular to an environmentally friendly adhesive coating machine with an adhesive recycling structure. Background Technology

[0002] When it is necessary to adjust the angle of the glue applicator relative to the paper feed tube, disassemble the mounting piece, rotate the rotating plate relative to the wall plate to a suitable angle, and then connect and fix the rotating plate and the wall plate through the mounting piece. In this way, the angle of the glue applicator relative to the paper feed tube can be adjusted, which can make the glue on the paper surface more even and the glue application precision higher.

[0003] A search revealed that Chinese Patent CN208131385U discloses a glue coating machine. During paper transport, a glue coating head contacts the moving paper to apply adhesive from its surface to the paper surface. However, the adhesive coating on the paper surface has poor smoothness and low precision, failing to meet high-precision coating requirements. Therefore, when adjusting the angle of the glue coating head relative to the paper feed tube, the mounting components are disassembled, allowing the rotating plate to rotate relative to the wall plate to a suitable angle. The rotating plate is then connected and fixed to the wall plate using the mounting components. This allows for adjustment of the angle of the glue coating head relative to the paper feed tube, resulting in better adhesive smoothness and higher coating precision on the paper surface.

[0004] Although the above-mentioned glue applicator improves the accuracy of glue application, when the glue is transported to the glue applicator roller using the glue storage tank, excess glue will drip directly from the glue applicator roller. The existing glue applicator is not convenient to recycle the dripping glue, which not only pollutes the working environment but is also not easy to reuse, resulting in a waste of glue resources.

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an environmentally friendly glue applicator with a glue recycling structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an environmentally friendly glue applicator with a glue recycling structure, comprising a mounting frame, a glue receiving frame fixedly connected to the lower surface of the mounting frame, a first variable speed motor fixedly mounted on one side of the mounting frame, a glue applicator roller fixedly connected to the output end of the first variable speed motor, an auxiliary roller rotatably connected inside the mounting frame, a scraper fixedly connected to one side of the mounting frame, a glue storage tank fixedly connected to the top inside the mounting frame, two connecting pipes penetrating the lower surface of the glue storage tank, a solenoid valve penetrating the outside of the connecting pipes, a glue outlet pipe penetrating one end of the two connecting pipes, a plurality of glue outlet heads penetrating the lower surface of the glue outlet pipe, and a recycling component provided on the lower surface of the glue receiving frame.

[0007] As a further description of the above technical solution:

[0008] The recycling assembly includes a conveying pipe that is connected to the lower surface of the glue receiving frame. A conveying pump is installed through the outside of the conveying pipe, and one end of the conveying pipe is connected to the upper surface of the glue storage tank.

[0009] As a further description of the above technical solution:

[0010] A glue inlet pipe is connected through one side of the upper surface of the glue storage tank. A blocking cap is threaded to one end of the glue inlet pipe. A filter plate is installed inside the glue receiving frame. A hydraulic cylinder is fixedly installed on the lower surface of the glue receiving frame. Multiple slots are opened on one side of the filter plate.

[0011] As a further description of the above technical solution:

[0012] A protective frame is fixedly connected to the lower surface of the adhesive receiving frame. Multiple heating blocks are fixedly installed on the lower surface of the adhesive receiving frame. The multiple heating blocks are arranged inside the protective frame. A connecting block is fixedly connected to the output end of the hydraulic cylinder. A connecting rod is fixedly connected to one side of the connecting block. The connecting rod is slidably connected to one side of the adhesive receiving frame.

[0013] As a further description of the above technical solution:

[0014] One end of the connecting rod is fixedly connected to a push plate, and two limiting rods are fixedly connected inside the glue receiving frame. The push plate is slidably connected to the outside of the two limiting rods. A second variable speed motor is fixedly installed on one side of the glue receiving frame, and an agitator is fixedly connected to the output end of the second variable speed motor.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model utilizes a recycling component. The glue-receiving frame easily catches the glue dripping from the glue-applying roller, while the conveying pipe facilitates the return of the glue from the inside of the glue-receiving frame to the inside of the glue storage tank. During this process, the filter plate filters impurities from the dripping glue, and the pusher plate facilitates the movement of the glue stored inside the glue-receiving frame, improving the fluidity of the glue. At the same time, the heating block and stirring frame help heat and stir the glue, further improving its fluidity, facilitating its reuse, and reducing the occurrence of drying.

[0021] 2. This utility model utilizes the disassembly assembly. The stop rods facilitate the installation of the filter plate by blocking the bottom of the filter plate, while the fixing blocks on both sides block the top of the filter plate. At the same time, the E-shaped frame's slots limit the position of the filter plate, making it easy to lock the filter plate's position. This allows the filter plate to be quickly disassembled by simply pulling the E-shaped frame, facilitating timely replacement and cleaning of the filter plate. Attached Figure Description

[0033] As attached Figure 1 As shown, the recycling component includes a conveying pipe 12 for the return conveying of glue. The conveying pipe 12 is connected to the lower surface of the glue receiving frame 2. A conveying pump 13 is installed through the outside of the conveying pipe 12. One end of the conveying pipe 12 is connected to the upper surface of the glue storage tank 7. A glue inlet pipe 14 is connected through one side of the upper surface of the glue storage tank 7 for dispensing glue into the glue storage tank 7.

[0034] As attached Figure 2As shown, a hydraulic cylinder 16 is fixedly installed on the lower surface of the adhesive receiving frame 2, and a protective frame 17 is fixedly connected to the lower surface of the adhesive receiving frame 2. A connecting block 19 is fixedly connected to the output end of the hydraulic cylinder 16, which is used to drive the connecting rod 20 to move.

[0035] As attached Figure 7 As shown, the filter plate 15 has multiple holes and slots 32 on one side to facilitate engagement with the E-type frame 29.

[0036] As attached Figure 5 As shown, multiple heating blocks 18 are fixedly installed on the lower surface of the adhesive receiving frame 2 to heat the adhesive. The multiple heating blocks 18 are located inside the protective frame 17 to protect the heating blocks 18.

[0037] As attached Figure 4 As shown, a connecting rod 20 is fixedly connected to one side of the connecting block 19. The connecting rod 20 is slidably connected to one side of the glue receiving frame 2. A push plate 21 is fixedly connected to one end of the connecting rod 20, which is used to push the glue inside the glue receiving frame 2. Two limiting rods 22 are fixedly connected inside the glue receiving frame 2. The push plate 21 is slidably connected to the outside of the two limiting rods 22, which plays a limiting role on the push plate 21.

[0038] As attached Figure 3 As shown, a second variable speed motor 23 is fixedly installed on one side of the glue receiving frame 2. The output end of the second variable speed motor 23 is fixedly connected to a stirring frame 24, which facilitates the stirring of the glue, improves the fluidity of the glue, and improves the uniformity of the glue being heated.

[0039] As attached Figure 4 As shown, the inner wall of the glue receiving frame 2 has a groove 25. The inside of the glue receiving frame 2 is equipped with a disassembly assembly, which includes two blocking rods 26. The two blocking rods 26 are fixedly connected to both sides of the inner wall of the glue receiving frame 2 to limit the lower part of the filter plate 15. Fixing blocks 27 are fixedly connected to both sides of the inner wall of the glue receiving frame 2. The fixing blocks 27 are located above the blocking rods 26 and limit the upper part of the filter plate 15.

[0040] As attached Figure 6 As shown, one of the fixing blocks 27 has multiple mounting slots 28 inside for mounting springs 31 and limiting the movement of E-frames 29. E-frames 29 are slidably connected inside the multiple mounting slots 28. E-frames 29 and multiple holes 32 are engaged with each other. Limiting plates 30 are fixedly connected to the outside of E-frames 29 to limit the movement of E-frames 29. Springs 31 are fixedly connected to one side of limiting plates 30. Springs 31 are fixedly connected to the inner wall of mounting slots 28 to facilitate pushing E-frames 29.

[0041] Working principle: During use, the solenoid valve 9 is opened. The glue inside the glue storage tank 7, under the action of gravity, flows through the connecting pipe 8 to the bottom glue outlet pipe 10, and then is discharged through the glue outlet head 11, dripping onto the glue coating roller 4. When the glue coating roller 4 is driven to rotate by the output end of the first speed motor 3, the glue will be coated on the outside of the glue coating roller 4. When the glue coating roller 4 contacts the scraper 6 on one side, the glue will be scraped, thereby improving the uniformity of the glue on the outside of the glue coating roller 4. Under the drive of external force, the material passes between the auxiliary roller 5 and the glue coating roller 4 and is coated with glue by the glue coating roller 4. Some of the glue will drip down under the action of extrusion pressure. The dripping glue is filtered through the filter plate 15 and enters the filter. Upon reaching the inside of the glue receiving frame 2, when a large amount of glue is stored inside, the controller activates the heating block 18 for preheating. Then, the second variable speed motor 23 is started, causing its output end to drive the stirring frame 24 to rotate inside the groove 25. When the hydraulic cylinder 16 is activated, its output end drives the connecting block 19 to pull the connecting rod 20 to slide on one side of the glue receiving frame 2, which in turn pulls the push plate 21 to push the glue inside the glue receiving frame 2 to the groove 25, so that the glue is heated and stirred at the same time. Then, the delivery pump 13 is started. The input end of the delivery pump 13 is connected through the delivery pipe 12 to deliver the glue to the inside of the glue storage tank 7, thereby completing the reuse of the glue.

[0042] When the filter plate 15 becomes clogged and needs to be disassembled for cleaning, pull the E-frame 29 so that the E-frame 29 drives the limiting plate 30 to press against the spring 31, thereby causing one end of the E-frame 29 to disengage from the multiple slots 32, the filter plate 15 is released from the limit, and then the filter plate 15 is slidably pulled away from the stop rod 26 and the fixing block 27 to complete the disassembly.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
