Abstract

This utility model discloses a corrugated paper gluing assembly, including a conveying device and a mounting frame. The mounting frame is fixedly installed on the top of the conveying device. The mounting frame is U-shaped, and a fixing plate is fixedly installed on one side of the top of the mounting frame. A collection box is fixedly installed on the fixing plate, and a vacuum cleaner is fixedly connected to the collection port of the collection box. A suction pipe is fixedly installed at the suction port of the vacuum cleaner. This utility model can clean the corrugated paper passing through. Before gluing, the vacuum cleaner and suction pipe adsorb paper scraps on the surface of the corrugated paper, making the surface of the corrugated paper cleaner and preventing paper scraps from continuing to adhere to the corrugated paper and mixing with the glue.

Description

Technical Field

[0001] This utility model relates to the field of corrugated paper coating technology, and in particular to a corrugated paper coating component. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper that has been processed by corrugating rollers. Therefore, gluing equipment is required when producing corrugated paper to facilitate bonding.

[0003] Existing gluing equipment does not pre-treat the corrugated paper during the gluing process. If residual paper scraps on the corrugated paper are not cleaned properly, they will mix with the glue. Since the adhesion of paper scraps is weak, the glue mixed with paper scraps will reduce the tack, making the corrugated paper and the facing paper not bond firmly, thus affecting the production quality of the corrugated paper. On the other hand, most existing gluing equipment uses gluing rollers for the gluing operation. The amount of glue applied by the gluing roller is not easy to control, and it is easy to have more glue in one place and less glue in another. Moreover, the gluing roller cannot scrape the glue after application, which can easily lead to uneven gluing.

[0004] In view of the technical problems existing in the prior art, this utility model provides a corrugated paper coating component to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a corrugated paper coating component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A corrugated paper coating assembly includes a conveying device and a mounting frame. The mounting frame is fixedly installed at the top of the conveying device and is U-shaped. A fixing plate is fixedly installed on one side of the top of the mounting frame, and a collection box is fixedly installed on the fixing plate. A vacuum cleaner is fixedly connected to the collection port of the collection box, and a suction pipe is fixedly installed at the suction port of the vacuum cleaner. The opening of the suction pipe is located directly above the conveying device. Two triggering mechanisms are provided on the inner top surface of the mounting frame. Each triggering mechanism includes a mounting base fixedly installed on the inner top surface of the mounting frame. The mounting base is U-shaped, and a first sensing plate is fixedly installed on the inner bottom surface of the mounting base. First springs located on both sides of the first sensing plate are fixedly installed on the inner bottom surface of the mounting base. A common abutment is fixedly installed at one end of each of the two first springs. The abutment is slidably connected to the U-shaped opening of the mounting base. A second sensing plate is fixedly installed at the top of the abutment, and the second sensing plate is located directly below the first sensing plate.

[0008] Preferably, multiple U-shaped seats are fixedly installed on both inner sidewalls of the mounting frame, the multiple U-shaped seats are arranged at equal intervals, and guide rods are fixedly installed between the two inner sidewalls of the multiple U-shaped seats.

[0009] Preferably, a connecting plate is slidably mounted on each of the multiple guide rods, and a second spring is sleeved on each of the multiple guide rods. One end of each of the multiple second springs is fixedly connected to the connecting plate, and the other end of each of the multiple second springs is fixedly connected to the inner top wall of the U-shaped seat.

[0010] Preferably, one end of each of the plurality of connecting plates is rotatably connected to a guide wheel, and the plurality of guide wheels are located above the conveying device.

[0011] Preferably, a glue storage tank is fixedly installed on the top of the mounting frame, and four glue injection nozzles are fixedly installed at equal intervals on the inner bottom surface of the mounting frame. All four glue injection nozzles are connected to the glue storage tank, and the two first sensing plates are electrically connected to the two adjacent glue injection nozzles.

[0012] Preferably, a scraper is rotatably connected between the two inner sidewalls of the mounting frame, and the four glue injection nozzles are all located between the scraper and the suction pipe. A handwheel is rotatably connected to the outer sidewall of the mounting frame, and the handwheel is fixedly connected to the rotating shaft of the scraper.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This utility model has a dust suction pipe, a vacuum cleaner and a collection box set above the conveying device, which can clean the corrugated paper that passes through. Before applying glue, the vacuum cleaner and the dust suction pipe can absorb the paper scraps on the surface of the corrugated paper, making the surface of the corrugated paper cleaner and preventing paper scraps from continuing to adhere to the corrugated paper and mixing with the glue, which facilitates the subsequent glue application and reduces the possibility of the glue not being firmly bonded.

[0015] 2. This utility model, by setting up a handwheel, scraper, glue nozzle, mounting base, stop block, first spring, first sensing plate, second sensing plate, U-shaped base, connecting plate, guide rod, and second spring, realizes real-time glue application to corrugated paper. Glue is only sprayed when the corrugated paper passes through the glue nozzle, ensuring that the glue falls directly onto the corrugated paper each time, avoiding glue falling onto the conveying device. At the same time, the scraper at the rear scrapes the glue evenly, increasing the bonding area and making the glue application more uniform, effectively improving the bonding quality.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A corrugated paper coating assembly includes a conveying device 1 and a mounting frame 7. The conveying device 1 consists of a support, a conveyor belt, conveyor rollers, and a motor, representing mature and commonly used existing technology. The mounting frame 7 is fixedly installed on the top of the conveying device 1. The mounting frame 7 is U-shaped, and a fixing plate 6 is fixedly installed on one side of the top of the mounting frame 7. A collection box 5 is fixedly installed on the fixing plate 6. A vacuum cleaner 4 is fixedly connected to the collection port of the collection box 5, and a suction pipe 3 is fixedly installed at the suction port of the vacuum cleaner 4. The opening of the suction pipe 3 is located directly above the conveying device 1 to facilitate the removal of paper scraps from the corrugated paper, reducing the impact of paper scraps on the adhesion. Two triggering mechanisms are provided on the inner top surface of the mounting frame 7. The triggering mechanisms include components fixedly installed on the mounting frame 7. The mounting base 11 on the inner top surface is U-shaped. A first sensing plate 14 is fixedly mounted on the inner bottom surface of the mounting base 11. A first spring 13 located on both sides of the first sensing plate 14 is fixedly mounted on the inner bottom surface of the mounting base 11. The first spring 13 has a low elastic coefficient, and the corrugated paper can also make the abutment 12 move upward. The same abutment 12 is fixedly mounted on one end of the two first springs 13. The abutment 12 is slidably connected to the U-shaped opening of the mounting base 11. The bottom surface of the abutment 12 is very close to the surface of the conveying device 1, so that the corrugated paper can press against the abutment 12 and make the abutment 12 rise. A second sensing plate 15 is fixedly mounted on the top of the abutment 12. The second sensing plate 15 is located directly below the first sensing plate 14.

[0024] In this utility model, multiple U-shaped seats 16 are fixedly installed on both inner side walls of the mounting frame 7. The multiple U-shaped seats 16 are arranged at equal intervals. Guide rods 18 are fixedly installed between the two inner side walls of the multiple U-shaped seats 16. Connecting plates 17 are slidably installed on the multiple guide rods 18. Second springs 19 are sleeved on the multiple guide rods 18. One end of the multiple second springs 19 is fixedly connected to the connecting plate 17, and the other end of the multiple second springs 19 is fixedly connected to the inner top wall of the U-shaped seat 16. Under the action of the second springs 19, the guide wheels 2 will abut against the corrugated paper on the conveying device 1, which plays a limiting role, prevents the corrugated paper from shifting, and prevents glue from spraying elsewhere. One end of the multiple connecting plates 17 is rotatably connected to the guide wheels 2. The multiple guide wheels 2 are all located above the conveying device 1, and the rotation direction of the guide wheels 2 is the same as the rotation direction of the conveying device 1.

[0025] In this utility model, a glue storage tank 20 is fixedly installed on the top of the mounting frame 7. Four glue injection nozzles 8 are fixedly installed at equal intervals on the inner bottom surface of the mounting frame 7. All four glue injection nozzles 8 are connected to the glue storage tank 20. Two first sensing plates 14 are electrically connected to two adjacent glue injection nozzles 8. When the first sensing plate 14, the second sensing plate 15 and the glue injection nozzles 8 form a circuit, the glue injection nozzles 8 will spray glue, forming a trigger circuit. Glue is sprayed only when passing through corrugated paper. A scraper 10 is rotatably connected between the two inner side walls of the mounting frame 7. All four glue injection nozzles 8 are located between the scraper 10 and the suction pipe 3. A handwheel 9 is rotatably connected to the outer side wall of the mounting frame 7 to facilitate adjustment of the angle of the scraper 10, which can scrape glue on corrugated paper of different thicknesses. The handwheel 9 is fixedly connected to the rotating shaft of the scraper 10.

[0026] The detailed working process of this utility model is as follows:

[0027] The corrugated paper is placed on the conveyor 1, and the guide wheels 2 on both sides press against the edge of the corrugated paper to limit its movement and prevent it from shifting. When the corrugated paper passes the stop block 12, the stop block 12 moves upward, so that the first sensing plate 14 and the second sensing plate 15 come into contact. The glue nozzle 8 is energized and begins to apply glue. When the corrugated paper leaves the stop block 12, the first sensing plate 14 and the second sensing plate 15 disengage, and the glue nozzle 8 stops applying glue. Then it passes through the scraper 10, which smooths the glue. The angle of the scraper 10 can be adjusted by the handwheel 9 to accommodate corrugated paper of different thicknesses.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
