Description

Technical Field

[0001] This utility model relates to the field of adhesive roller technology, and in particular to an adhesive roller device for corrugated paper used in carton production. Background Technology

[0002] In the production process of cardboard boxes, two relatively rotating pressure rollers are used to bond and press the corrugated core paper and face paper together with adhesive. In actual operation, during the pressing process, some adhesive is easily squeezed out between the corrugated core paper and face paper, thus sticking to the surface of the pressure rollers. With long-term use, the adhesive will continuously adhere to the surface of the pressure rollers and then be transferred from the pressure rollers to the surface of the corrugated paper, thereby reducing the forming quality of the corrugated paper. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where adhesive is easily squeezed out between the corrugated core paper and the face paper during the pressing process, thereby reducing the forming quality of the corrugated paper. Therefore, this invention proposes a corrugated paper bonding pressure roller device for carton production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a corrugated paper bonding roller device for carton production, including a U-shaped frame with two rotating shafts rotatably connected through it. Pressure rollers are fixedly connected to the circumference of the rotating shafts. An adhesive cleaning assembly is fixedly connected to the side of the U-shaped frame. The adhesive cleaning assembly includes two U-shaped plates fixedly connected to the U-shaped frame. A reciprocating screw is rotatably connected to the U-shaped plate. A first sprocket and a second sprocket are fixedly connected to the ends of the two reciprocating screws, respectively. A chain belt is provided for transmission between the first sprocket and the second sprocket. A scraper is provided on the reciprocating screw, and the scraper slides in cooperation with the U-shaped plate.

[0006] Preferably, the U-shaped frame has two ear plates symmetrically fixedly connected to its side, each ear plate has a slide rod fixedly connected to it, a scraper is slidably connected between the two slide rods, and a spring is fixedly connected between the scraper and the ear plate.

[0007] Preferably, two adhesive shaving blades are symmetrically fixedly connected to the scraping frame. The adhesive shaving blades are in contact with the pressure roller, and the two adhesive shaving blades are arranged opposite to each other. The scraper abuts against the adhesive shaving blades.

[0008] Preferably, the pressure roller has a cavity, and an electric heating wire is fixedly connected inside the cavity.

[0009] Preferably, a connecting plate is symmetrically and fixedly connected to the bottom surface of the U-shaped plate, and a collecting hopper is fixedly connected to the bottom surface of the connecting plate, with the collecting hopper located below the adhesive shaving blade.

[0010] Preferably, the scraping frame has an opening, and cardboard can be inserted between the two pressure rollers and the opening.

[0011] Preferably, the gap between the two pressure rollers is smaller than the width of the paperboard.

[0012] Preferably, a gear is fixedly connected to the end of the rotating shaft, and the two gears mesh with each other.

[0013] The present invention discloses a corrugated paper bonding roller device for carton production. The advantages are as follows: When the two pressure rollers rotate in opposite directions, the adhesive on the surface of the pressure rollers is scraped off by the adhesive scraper. The drive motor drives the reciprocating screw to rotate, thereby driving the scraper to move continuously back and forth along the surface of the adhesive scraper. This can push out the adhesive accumulated on the adhesive scraper, thus avoiding the disadvantage of adhesive coming into contact with the surface of the corrugated cardboard and causing a reduction in the quality of corrugated paper forming.

[0020] 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.

[0021] Example 1

[0022] Reference Figure 1-4This utility model is a corrugated paper bonding roller device for carton production, including a U-shaped frame 1, two rotating shafts 2 are rotatably connected through the U-shaped frame 1, pressure rollers 3 are fixedly connected to the sides of the rotating shafts 2, an adhesive cleaning assembly is fixedly connected to the side of the U-shaped frame 1, the adhesive cleaning assembly includes two U-shaped plates 6, the U-shaped plates 6 are fixedly connected to the U-shaped frame 1, a reciprocating screw 7 is rotatably connected to the U-shaped plates 6, a first sprocket 9 and a second sprocket 5 are fixedly connected to the ends of the two reciprocating screws 7 respectively, a second sprocket 5 is fixedly connected to the sides of one rotating shaft 2, a chain belt 10 is provided between the first sprocket 9 and the second sprocket 5 for transmission, and a scraper 8 is provided on the reciprocating screw 7, the scraper 8 is slidably engaged with the U-shaped plates 6.

[0023] The operation process of this embodiment is as follows: In the initial state, the corrugated paper is divided into corrugated core paper and face paper. After the adhesive is applied to the core paper, the core paper and face paper are aligned and placed between two pressure rollers 3. The two pressure rollers 3 rotate in opposite directions. After the corrugated paper passes through the gap between the pressure rollers 3, the pressing operation is completed. During the pressing, the adhesive is squeezed out from both sides of the corrugated cardboard 19 due to the pressure, thereby contaminating the surface of the pressure rollers 3.

[0024] A drive motor is fixedly installed on the side of a U-shaped plate 6. The output end of the drive motor is fixedly connected to a reciprocating lead screw 7. The drive motor drives one reciprocating lead screw 7 to rotate, and the second sprocket 5 rotates. The rotation of the second sprocket 5 is transmitted through the chain belt 10, which drives the two reciprocating lead screws 7 to rotate synchronously in the same direction. Due to the sliding fit between the scraper 8 and the U-shaped plate 6, as the reciprocating lead screw 7 rotates, the two scrapers 8 reciprocate along the side of their respective pressure rollers 3. The maximum movement path of the scraper 8 is greater than the length of the pressure roller 3. When the scraper 8 moves on the side of the pressure roller 3, it carries away the adhesive adhering to the surface of the pressure roller 3.

[0025] Example 2

[0026] Since the pressure roller 3 is constantly rotating, it is difficult for the scraper 8 alone to remove all the colloid. Therefore, please refer to [link / reference needed]. Figure 1-2 Based on the first specific embodiment, two ear plates 11 are symmetrically fixedly connected to the side of the U-shaped frame 1. A slide rod 12 is fixedly connected to the ear plate 11. A scraping frame 13 is slidably connected between the two slide rods 12. A spring 15 is fixedly connected between the scraping frame 13 and the ear plate 11. Two adhesive shaving blades 14 are symmetrically fixedly connected to the scraping frame 13. The adhesive shaving blades 14 are in contact with the pressure roller 3. The two adhesive shaving blades 14 are arranged opposite to each other. The scraper 8 abuts against the adhesive shaving blades 14. A through hole is opened in the scraping frame 13. A cardboard 19 can be inserted between the two pressure rollers 3 and the through hole. The gap between the two pressure rollers 3 is smaller than the width of the cardboard 19. A gear 4 is fixedly connected to the end of the rotating shaft 2. The two gears 4 mesh with each other.

[0027] The operation process of this embodiment is as follows: A motor is fixedly connected to the side of the U-shaped frame 1, and the output end of the motor is fixedly connected to a rotating shaft 2. The motor drives the rotating shaft 2 to rotate. Since the two gears 4 mesh with each other, the two pressure rollers 3 rotate in opposite directions to press the cardboard 19 passing through.

[0028] Spring 15 continuously pulls scraper 13 and adhesive shaving blade 14 toward pressure roller 3. Adhesive shaving blade 14 is always kept in contact with pressure roller 3 to prevent wear on the blade and gaps from forming between it and pressure roller 3 after prolonged use. As the two pressure rollers 3 continue to rotate, the adhesive is blocked and located on the surface of adhesive shaving blade 14. Since scraper 8 and adhesive shaving blade 14 are in contact, scraper 8 reciprocates to push the adhesive on adhesive shaving blade 14 out. That is, adhesive shaving blade 14 first completely gathers the adhesive on the surface of pressure roller 3, and then scraper 8 pushes the adhesive on adhesive shaving blade 14 out, which can prevent adhesive residue from reducing the quality of cardboard 19.

[0029] Example 3

[0030] After scraper 8 pushes out the adhesive, the adhesive falls directly down, which can cause pollution to the surrounding environment. Therefore, please refer to [the relevant documentation]. Figure 2-3 Based on the first specific embodiment, a cavity is opened in the pressure roller 3, and an electric heating wire 18 is fixedly connected in the cavity. A connecting plate 16 is symmetrically fixedly connected to the bottom surface of the U-shaped plate 6, and a collecting hopper 17 is fixedly connected to the bottom surface of the connecting plate 16. The collecting hopper 17 is located below the adhesive shaving knife 14.

[0031] The operation process of this embodiment is as follows: after the scraper 8 pushes out the adhesive, the adhesive falls into the collection hopper 17 for collection. During the operation of the device, the electric heating wire 18 continues to heat up to prevent the adhesive from sticking to the pressure roller 3 and solidifying, which would make it difficult for the scraper 8 to scrape it off, thereby further improving the ability to process the adhesive on the surface of the pressure roller 3.

[0032] 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.
