Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, specifically to a corrugated cardboard flattening device for corrugated paper processing. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper. It has good elasticity and extensibility and is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. In the production process, corrugated cardboard requires multiple layers to be bonded together. In order to secure the multiple layers of corrugated cardboard together, a corrugated cardboard flattening device is required.

[0003] Utility model patent CN218804378U discloses a corrugated cardboard flattening device for corrugated paper processing. The device includes two side plates, with multiple equally spaced conveyor shafts rotatably connected between them via bearings. A belt is placed between the right ends of the foremost and rearmost conveyor shafts, and each conveyor shaft is connected to the others via belt drive. This device, through the cooperation of a rod, U-shaped frame, spring, and pressure cylinder, achieves the effect of flattening corrugated cardboard of different thicknesses by using the spring's return force to drive the pressure cylinder to compress the cardboard during conveyor shaft transport. The cooperation of a drying shaft and fan blades allows for airflow into the core paper of the corrugated cardboard during the flattening process, accelerating the airflow inside the cardboard and promoting rapid curing of the adhesive.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: Although the device dries the adhesive quickly by blowing air, it only relies on mechanically driven fan blades to blow air, resulting in uneven air distribution and inconsistent adhesive solidification speed. This causes the adhesive to easily flow out from the surface of the cardboard during the flattening process and adhere to the surface of the belt. Consequently, when the cardboard is placed later, it is easy for it to come into contact with the adhesive residue on the surface of the belt, affecting the quality of the cardboard products. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model proposes a corrugated cardboard flattening device for corrugated paper processing to solve the problems mentioned above.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A corrugated cardboard flattening device for corrugated paper processing includes a conveying mechanism, a conveyor belt on the surface of the conveying mechanism, multiple guide grooves on the surface of the conveyor belt, a C-shaped shell on the top of the conveying mechanism, a glue removal mechanism below the guide grooves, multiple flattening mechanisms on the surface of the C-shaped shell, drying mechanisms on both sides of the C-shaped shell, and a controller on one side of the conveying mechanism.

[0008] The adhesive removal mechanism includes an extension plate, a first electric push rod fixed to the bottom of the extension plate, one end of the first electric push rod passing through the extension plate and fixed to a collection shell, a main scraper fixed to the top of the collection shell, the main scraper being slidably connected to the bottom of the conveyor belt, multiple secondary scrapers fixed to the top of the main scraper, the tops of the secondary scrapers being slidably connected to the surface of the guide groove, a cleaning door hinged to the surface of the collection shell, and a first guide rod slidably connected to the surface of the extension plate, the top end of the first guide rod being fixedly connected to the bottom of the collection shell.

[0009] Preferably, the conveying mechanism includes a base, four first support plates and two second support plates are fixed to the top of the base, and mounting plates are fixed to the top of both the first and second support plates. There are two mounting plates, and two conveying shafts are rotatably connected between the mounting plates on both sides. A drive motor is fixed to the surface of one mounting plate, and the output shaft of the drive motor passes through the mounting plate and is fixedly connected to the surface of the conveying shaft. The conveyor belt is sleeved on the surfaces of the two conveying shafts. An extension plate is fixed to the opposite surfaces of the two second support plates. A support partition is fixed between the two mounting plates, and the surface of the support partition is slidably connected to the inner wall of the conveyor belt.

[0010] Preferably, an extension frame is fixed to the surface of the second support plate, and an extension guide shell is fixed between the two extension frames. The extension guide shell has an inclined structure design, and a groove is opened on the surface of the collection shell. The surface of the extension guide shell is slidably connected to the surface of the groove, and the extension guide shell is located below the conveyor belt.

[0011] Preferably, a telescopic cover is fixed to the bottom of the extended guide shell, and the bottom of the telescopic cover is fixedly connected to the bottom of the groove of the collection shell.

[0012] Preferably, the flattening mechanism includes a second electric push rod, which is fixed to the top of the C-shaped shell. One end of the second electric push rod passes through the C-shaped shell and is fixed with a pressure sensor. A combined shell is fixed to the bottom of the pressure sensor, and multiple pressure rollers are rotatably connected to the surface of the combined shell.

[0013] Preferably, four second guide rods are fixed to the top of the combined shell, and the surfaces of the second guide rods slide through the C-shaped shell.

[0014] Preferably, the air drying mechanism includes a mounting frame and an exhaust shell. A fan is fixed to the top of the mounting frame. The exhaust shell is connected to the surface of the C-shaped shell. A diversion pipe is connected to the surface of the fan. The diversion pipe is connected to the exhaust shell. An electric heating wire is fixed to the inner wall of the exhaust shell. The two exhaust shells are arranged opposite to each other.

[0015] Compared with the prior art, the beneficial effects of this utility model of a corrugated cardboard flattening device for corrugated paper processing are:

[0016] First, the adhesive removal mechanism of this device achieves efficient removal and collection of adhesive liquid through the coordinated action of the main scraper and the auxiliary scraper, combined with the diversion channel. Compared with the traditional device that relies on manual cleaning or a single scraper design, this device significantly reduces the residue of adhesive liquid on the conveyor belt surface, avoiding cardboard contamination and equipment jamming caused by adhesive liquid accumulation. The opening of the diversion channel further optimizes the flow path of adhesive liquid, and with the inclined diversion of the extended guide shell, it ensures centralized recycling of adhesive liquid and reduces cleaning and maintenance costs.

[0017] Secondly, the drying mechanism adopts a design of electric heating wire heating and symmetrical air supply with double-sided exhaust shells, which makes the cardboard evenly heated on both sides, greatly improving the curing speed of the adhesive. At the same time, it avoids the cardboard warping problem caused by high temperature on one side. The flattening mechanism achieves precise adjustment of the pressure roller pressure through closed-loop control of the second electric push rod and pressure sensor, which can adapt to the processing needs of cardboard of different thicknesses. It solves the technical defects of uneven pressure and easy overload of traditional spring flattening. The distribution design of multiple pressure rollers further disperses the pressure, ensuring that the bonding strength of each area of ​​the cardboard is consistent, and the yield of finished products is significantly improved.

[0025] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0026] Please refer to the specific embodiment of the corrugated cardboard flattening device for corrugated paper processing. Figure 1 — Figure 6 It includes a conveying mechanism 1, a conveyor belt 2 on the surface of the conveying mechanism 1, multiple guide grooves 3 on the surface of the conveyor belt 2, a C-shaped shell 4 on the top of the conveying mechanism 1, a glue removal mechanism 5 below the guide grooves 3, multiple flattening mechanisms 6 on the surface of the C-shaped shell 4, air drying mechanisms 7 on both sides of the C-shaped shell 4, and a controller 8 on one side of the conveying mechanism 1.

[0027] The adhesive removal mechanism 5 includes an extension plate 501. A first electric push rod 502 is fixed to the bottom of the extension plate 501. One end of the first electric push rod 502 passes through the extension plate 501 and is fixed to a collection shell 503. A main scraper 504 is fixed to the top of the collection shell 503. The main scraper 504 is slidably connected to the bottom of the conveyor belt 2. Multiple secondary scrapers 505 are fixed to the top of the main scraper 504. The top of the secondary scrapers 505 is slidably connected to the surface of the guide trough 3. A cleaning door 506 is hinged to the surface of the collection shell 503. A first guide rod 507 is slidably connected to the surface of the extension plate 501. The top end of the first guide rod 507 is fixedly connected to the bottom of the collection shell 503.

[0028] Through the above technical solution, the conveyor belt 2 on the surface of the conveying mechanism 1 carries the corrugated cardboard. The guide groove 3 on the surface of the conveyor belt 2 is used to guide the overflowing glue to a designated area, avoiding disorderly diffusion of the glue on the surface. The C-shaped shell 4 serves as the main support structure, integrating the flattening mechanism 6 and the drying mechanism 7, so that the flattening and curing functions can be performed simultaneously. The glue removal mechanism 5 drives the collection shell 503 to rise and fall vertically through the first electric push rod 502, so that the main scraper 504 is attached to the bottom of the conveyor belt 2 and the secondary scraper 505 is embedded in the guide groove 3. The scraping action removes the residual glue from the surface of the conveyor belt 2 and the guide groove 3. The cleaned glue is temporarily stored in the collection shell 503 and then passed through the cleaning door. Regular cleaning is performed at 506. The first guide rod 507 ensures the stability of the collection shell 503 during lifting. The controller 8 coordinates the operation of each module. Through the collaborative design of the guide channel 3 and the glue removal mechanism 5, this mechanism achieves efficient collection and automatic cleaning of glue, solving the problems of cardboard contamination and equipment maintenance caused by glue residue in traditional devices. The double-layer glue scraping structure of the main scraper 504 and the auxiliary scraper 505 can cover the surface of the conveyor belt 2 and the inside of the guide channel 3, avoiding dead corner residue. The lifting design of the collection shell 503 allows the main scraper 504 and the auxiliary scraper 505 to stop contacting the surface of the conveyor belt 2 when cleaning is not required, thus improving the service life of the conveyor belt 2.

[0029] The conveying mechanism 1 includes a base 101. Four first support plates 102 and two second support plates 103 are fixed to the top of the base 101. Mounting plates 104 are fixed to the top of both the first support plates 102 and the second support plates 103. There are two mounting plates 104. Two conveying shafts 105 are rotatably connected between the two mounting plates 104. A drive motor 106 is fixed to the surface of one mounting plate 104. The output shaft of the drive motor 106 passes through the mounting plate 104 and is fixedly connected to the surface of the conveying shaft 105. The conveyor belt 2 is sleeved on the surface of the two conveying shafts 105. An extension plate 501 is fixed to the opposite surface of the two second support plates 103. A support partition 107 is fixed between the two mounting plates 104. The surface of the support partition 107 is slidably connected to the inner wall of the conveyor belt 2.

[0030] Through the above technical solution, the conveying mechanism 1 is supported by the base 101. The first support plate 102 and the second support plate 103 are used to fix the mounting plate 104 to ensure the stable rotation of the conveying shaft 105. The drive motor 106 drives the conveying shaft 105 to drive the conveyor belt 2 to rotate in a cycle. The support partition 107 fits against the inner wall of the conveyor belt 2 to prevent the conveyor belt 2 from collapsing and deforming under load. The extension plate 501 is fixed to the second support plate 103 to provide a mounting base for the glue removal mechanism 5.

[0031] An extension frame 508 is fixed on the surface of the second support plate 103, and an extension guide shell 510 is fixed between the two extension frames 508. The extension guide shell 510 has an inclined structure design. A groove is opened on the surface of the collection shell 503. The surface of the extension guide shell 510 is slidably connected to the surface of the groove. The extension guide shell 510 is located below the conveyor belt 2.

[0032] Through the above technical solution, the extended guide shell 510 guides the adhesive dripping from the bottom of the conveyor belt 2 to the designated collection area, so that the adhesive can fall into the collection shell 503 in a uniform manner.

[0033] The bottom of the extended guide shell 510 is fixed with a telescopic cover 509, and the bottom of the telescopic cover 509 is fixedly connected to the bottom of the groove of the collection shell 503.

[0034] Through the above technical solution, the telescopic cover 509 covers the connection between the extended guide shell 510 and the collection shell 503, and can rise and fall with the collection shell 503 to prevent glue leakage.

[0035] The flattening mechanism 6 includes a second electric push rod 601, which is fixed to the top of the C-shaped shell 4. One end of the second electric push rod 601 passes through the C-shaped shell 4 and is fixed with a pressure sensor 602. The bottom of the pressure sensor 602 is fixed with a combined shell 603, and multiple pressure rollers 604 are rotatably connected to the surface of the combined shell 603.

[0036] Through the above technical solution, the flattening mechanism 6 drives the pressure sensor 602 and the combined housing 603 to press down through the second electric push rod 601. Multiple pressure rollers 604 evenly contact the surface of the cardboard. The pressure sensor 602 feeds back pressure data to the controller 8 in real time, dynamically adjusting the downward pressure of the pressure rollers 604. The design of multiple pressure rollers 604 disperses the pressure, avoiding local overpressure that could cause cardboard deformation. The closed-loop control of the pressure sensor 602 and the electric push rod achieves precise flattening, adapting to cardboard of different thicknesses, and is more stable than traditional spring flattening.

[0037] Four second guide rods 605 are fixed to the top of the combined shell 603, and the surface of the second guide rods 605 slides through the C-shaped shell 4.

[0038] Through the above technical solution, the second guide rod 605 restricts the combined shell 603 to move only in the vertical direction, ensuring that the pressure roller 604 is in parallel contact with the paperboard surface.

[0039] The air drying mechanism 7 includes a mounting frame 701 and an exhaust shell 703. A fan 702 is fixed on the top of the mounting frame 701. The exhaust shell 703 is connected to the surface of the C-shaped shell 4. A diversion pipe 704 is connected to the surface of the fan 702. The diversion pipe 704 is connected to the exhaust shell 703. An electric heating wire 705 is fixed on the inner wall of the exhaust shell 703. The two exhaust shells 703 are arranged opposite to each other.

[0040] Through the above technical solution, the fan 702 delivers the airflow to the exhaust shell 703 through the diversion pipe 704. The heating wire 705 heats the airflow and blows it evenly onto the surface of the cardboard to accelerate the curing of the adhesive. The heating wire 705 provides controllable hot air, which is more efficient than natural air drying. The symmetrical design of the exhaust shell 703 ensures that the cardboard is heated evenly on both sides, avoiding deformation caused by overheating on one side.

[0041] Its working principle is as follows: Corrugated cardboard is carried by the conveyor belt 2 of the conveying mechanism 1 into the C-shaped shell 4. The second electric push rod 601 of the flattening mechanism 6 drives the pressure roller 604 to press down according to the command of the controller 8. The pressure sensor 602 monitors and adjusts the pressure in real time to ensure that the cardboard is evenly pressed and bonded. During the flattening process, the overflowing glue liquid is collected in the guide groove 3 through the surface of the conveyor belt 2. The first electric push rod 502 of the glue removal mechanism 5 drives the main scraper 504 and the auxiliary scraper 505 to scrape off the residual glue liquid. The glue liquid is introduced into the extended guide shell 510 or falls directly into the collection shell 503. The fan 702 and the heating wire 705 of the drying mechanism 7 generate hot air, which is blown onto the surface of the cardboard through the exhaust shell 703 to accelerate the curing of the glue liquid and complete the flattening operation of the cardboard. The controller 8 coordinates the start and stop and parameter adjustment of the flattening, glue removal and drying modules to realize the full-process automated control.

[0042] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
