Description

Technical Field

[0001] This utility model relates to the field of base paper production technology, and in particular to a base paper production adhesive scraping device. Background Technology

[0002] Laminated boards are composite materials made by bonding multiple layers of materials together using a high-temperature, high-pressure process. They are widely used in electronics, construction, aerospace, and other fields. Their core characteristic is that by layering materials with different properties, they achieve comprehensive performance that cannot be achieved by a single material, such as high strength, lightweight, corrosion resistance, or insulation. In the electronics industry, laminated boards mainly refer to the substrate of printed circuit boards (PCBs), which are made by alternately pressing conductive layers (such as copper foil) and insulating layers (such as epoxy resin or polyimide) to support and connect electronic components.

[0003] A search revealed that patent CN221245877U discloses a scraping device for producing laminated board base paper. This device uses an air pump to push gas through an air pipe into a storage hopper. Under air pressure, the glue in the hopper is pushed through a discharge pipe into a sleeve, and then flows out through a first and second glue outlet hole onto the moving laminated board directly below. A solenoid valve controls the airflow, thereby controlling the glue flow and adjusting the glue application thickness. The sleeve, insert, and bidirectional electric actuator allow the extension length of the insert to be adjusted according to the size of the laminated board base paper. However, this device requires frequent adjustment of the insert position to match the glue application of base paper of different widths, making it inconvenient and slow to use. Furthermore, relying solely on a scraper cannot guarantee that the glue is evenly spread, thus requiring further improvement. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4As shown, a scraping device for producing base paper is disclosed, comprising a frame 1, a conveying assembly 2 installed inside the frame 1, and a motor 13 for driving the conveying assembly 2 to rotate installed on the outer wall of the frame 1. A top cover 4 is fixed at the middle of the top of the frame 1, a glue storage box 5 is fixed on one side of the upper surface of the top cover 4, a glue outlet pipe 6 is fixed through and fixed to the top of the top cover 4, a peristaltic pump 7 connecting the glue storage box 5 and the glue outlet pipe 6 is installed on the upper surface of the top cover 4, a through hole is opened in the top wall of the top cover 4, and a guide rod 10 is slidably connected inside the through hole. A scraping assembly 11 is fixed at the bottom end of the guide rod 10, an adjusting assembly 12 for adjusting the lifting and lowering of the scraping assembly 11 is provided through the top wall of the top cover 4, and a controller 14 is installed on the outer wall of the frame 1.

[0024] The conveying assembly 2 includes two shafts 21 rotatably connected to the frame 1. Rollers 22 are fixed on the surface of both shafts 21. A conveyor belt 23 is sleeved on the surface of both rollers 22. The output end of the motor 13 is fixedly connected to one of the shafts 21.

[0025] In this embodiment, after the motor 13 drives the corresponding shaft 21 to rotate, the roller 22 on the surface of the shaft 21 will drive the conveyor belt 23 to rotate. At this time, if there is base paper on the surface of the conveyor belt 23, the base paper can be conveyed.

[0026] A pallet 3 is horizontally fixed inside the frame 1 and inside the conveyor belt 23, with the upper surface of the pallet 3 in contact with the conveyor belt 23.

[0027] The pallet 3 can support the conveyor belt 23.

[0028] The peristaltic pump 7 is equipped with a hose 9 at its drive end. The glue storage box 5 has a glue extraction tube 8 that runs through and is fixed to its side wall. The two ends of the hose 9 are fixedly connected to the glue extraction tube 8 and the glue outlet tube 6, respectively.

[0029] After the air pump and peristaltic pump 7 are activated, the glue inside the glue storage box 5 is drawn out through the glue extraction tube 8. The glue is discharged along the hose 9 and the glue outlet tube 6, and finally drips from the bottom of the glue outlet tube 6 onto the base paper.

[0030] The top wall of the glue storage box 5 is provided with a feeding port 51, and the top of the feeding port 51 is connected to a top cover by a thread.

[0031] By unscrewing the top cover, glue can be added into the glue storage box 5 through the feeding port 51.

[0032] The scraping assembly 11 includes a horizontal plate 111 fixed to the bottom of the guide rod 10. A first scraper 112, a second scraper 113, and a third scraper 114 are fixed on the lower surface of the horizontal plate 111. The first scraper 112, the second scraper 113, and the third scraper 114 are all designed to be inclined. The first scraper 112 is V-shaped. The bottom heights of the first scraper 112, the second scraper 113, and the third scraper 114 decrease sequentially.

[0033] As the base paper on the surface of the conveyor belt 23 moves with the conveyor belt 23, the first V-shaped scraper 112 first pushes the glue to both sides, so that the glue covers the entire base paper. As the base paper continues to move, the second scraper 113 and the third scraper 114 further scrape the glue, so that the glue is evenly covered on the surface of the base paper.

[0034] Adjustment assembly 12 includes a lead screw 121 that penetrates the top wall of top cover 4 and is rotatably connected to top cover 4 via a bearing. The bottom surface of lead screw 121 is rotatably connected to an internal threaded tube 122 via a thread. The bottom end of internal threaded tube 122 is fixedly connected to the upper surface of horizontal plate 111. The surface of guide rod 10 is provided with scale lines.

[0035] In this embodiment, a knob is fixed to the top of the lead screw 121. By rotating the knob, the lead screw 121 is driven to rotate, and the lead screw 121 will drive the internal thread tube 122 to move along the direction of the guide rod 10. Thus, the internal thread tube 122 drives the horizontal plate 111 to rise and fall. The scale line value on the surface of the guide rod 10 corresponds to the bottom height of the third scraper 114. When reading, the value corresponding to the upper surface of the top cover 4 is the bottom height of the third scraper 114.

[0036] In this embodiment, the controller 14 adopts an S7-1200 series (small and medium-sized automation) CPU 1214C (6ES7214-1BG40-0XB0), and controls the operation of the motor 13 and the peristaltic pump 7 through the controller 14.

[0037] Working principle: When in use, place the base paper on the surface of the conveyor belt 23. The conveyor belt 23 drives the base paper to move. The peristaltic pump 7 draws out the glue from the glue storage box 5. The glue is discharged along the hose 9 and the glue outlet pipe 6, and finally drips from the bottom of the glue outlet pipe 6 onto the base paper. As the base paper moves, the first scraper 112, the second scraper 113 and the third scraper 114 gradually push the glue on the surface of the base paper, so that the glue is evenly covered on the surface of the base paper.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
