Description

Technical Field

[0001] This utility model relates to the technical field of glue-sealing equipment, specifically to a strip honeycomb cardboard glue-sealing machine. Background Technology

[0002] In the field of honeycomb paperboard production, strip honeycomb paperboard, as a new type of environmentally friendly packaging material, is widely used in various industries such as electronics, furniture, fragile goods transport packaging, building decoration, and transportation due to its lightweight, high strength, and recyclability. In its production process, the lamination stage is a key step that determines the bonding quality and finished product performance of the paperboard.

[0003] Traditional strip honeycomb paperboard lamination processes primarily rely on manual pressing or simple mechanical assistance. In manual pressing, workers must apply continuous pressure to the glued area on the outer layer of the paperboard before the glue has fully hardened to prevent detachment. While simple mechanical assistance improves production efficiency to some extent, it still has several shortcomings. For example, some equipment can only perform lamination with a single pressure, unable to flexibly adjust pressure parameters according to the different thicknesses and materials of the strip honeycomb paperboard. This results in excessive pressure on thin paperboard causing damage, and insufficient pressure on thick paperboard affecting the bonding effect. During lamination, glue easily overflows from the edges of the paperboard. Traditional equipment lacks an effective overflow removal mechanism, which not only contaminates the sides of the paperboard, affecting product appearance quality, but may also adhere to the equipment, increasing cleaning and maintenance difficulties, and even causing equipment malfunctions and reducing production continuity. Therefore, this paper proposes a strip honeycomb paperboard lamination machine solution. Utility Model Content

[0024] To provide a clearer explanation and description of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0025] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of each embodiment. Specific details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures. The disclosures of various publications, patents, and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solutions of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0026] Example 1: A drive motor 21 and a reducer 27 are fixed on the top left side of the base plate 1, and the two are connected by a coupling. Two bearing seats 25 are symmetrically installed on the left and right sides of the upper surface of the base plate 1. The bearing seats 25 have round holes and are fitted with matching sealed bearings. Two lower rotating rollers 24 are rotatably connected between the bearing seats 25 through the bearings. The two rollers are kept parallel and the distance between them is slightly greater than the thickness of the rubber scraper 314. A driven gear 22 is fixed to the left end of the lower rotating roller 24. A drive gear 26 is installed on the output shaft of the reducer 27. The drive gear 26 meshes with the rear driven gear 22. A transmission gear 23 is rotatably connected to the middle section of the left bearing seat 25. The transmission gear 23 meshes with the two driven gears 22 respectively. In the upper roller pressing mechanism 3, the bottom of the inverted U-shaped support frame 311 of the side glue overflow removal support 31 is fixed to the upper surface of the bearing seat 25. The electric push rod 312 is vertically installed in the middle of the support frame 311, and its telescopic shaft end is connected to the bearing 313. The bottom of the bearing 313 is fixed to the servo electric cylinder 315, and the rubber scraper 314 is horizontally connected through the telescopic shaft of the servo electric cylinder 315. The upper rotating roller 32 rotates through the space between the two supports 31, located directly above the gap of the lower rotating roller 24, forming a gap with the lower rotating roller 24 for the strip honeycomb paperboard to pass through.

[0027] Example 2: Based on Example 1, a T-shaped groove is opened on the top of the base plate 1, and a matching T-shaped slider is fixed to the bottom of the bearing seat 25. The left and right positions are adjustable by tightening bolts. After adjusting the spacing of the lower roller 24, the driven gear 22 and transmission gear 23 of the appropriate length are reinstalled to ensure gear meshing. The electric push rod 312 of the side glue overflow removal support 31 is replaced with a dual-axis electric push rod, whose dual telescopic shafts are respectively connected to the bearing 313. A detachable rubber scraper 314 is installed at the end of the telescopic shaft of the servo electric cylinder 315. Different width scrapers are used to adapt to different cardboard specifications. Pressure sensors are added to both ends of the upper roller 32. The extension and retraction of the electric push rod 312 is dynamically adjusted by the PLC controller to maintain a constant pressure with the lower roller 24.

[0028] Example 3: Based on Example 2, an electric heating wire is embedded inside the rubber scraper 314, and a temperature of 50-60℃ is maintained by a temperature controller to soften the adhesive. The servo cylinder 315 is replaced with a closed-loop servo cylinder with an encoder, which can programmably control the frequency and amplitude of the lateral reciprocating motion of the scraper 314. Infrared sensors are added to both sides of the inverted U-shaped support frame 311 to monitor the edge position of the cardboard in real time and automatically adjust the lateral position of the scraper 314 in conjunction with the servo cylinder 315. A spiral groove is added to the surface of the lower roller 24, which, together with the rubber coating of the upper roller 32, enhances the adhesive penetration. A collection tank is set below the lower roller 24 and connected to an adhesive recovery device through a negative pressure pipe to realize automatic recovery of overflow adhesive.

[0029] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: After the equipment is started, the drive motor 21 drives the reducer 27 to operate through the coupling. The drive gear 26 on the output shaft of the reducer 27 meshes with the driven gear 22 of the rear lower roller 24, driving the lower roller 24 to rotate. At the same time, the power is transmitted to the driven gear 22 of the front lower roller 24 through the transmission gear 23 in the middle section of the left bearing seat 25, realizing the synchronous and opposite rotation of the two lower rollers 24. The operator feeds the strip honeycomb paperboard to be glued from the left side of the equipment. The paperboard passes through the gap between the upper roller 32 and the lower roller 24. Since the distance between the two lower rollers 24 is greater than the thickness of the paperboard, the paperboard is conveyed forward under the friction of the rotating lower roller 24. At the same time, the upper roller 32 applies pressure to the paperboard through its own weight or pre-pressure, so that the glue is evenly spread and penetrates on the surface of the paperboard. During the lamination process, the telescopic shaft of the electric push rod 312 of the side glue removal support 31 is pre-adjusted to a suitable height according to the thickness of the cardboard, so that the bearing 313 is in the appropriate position. At this time, the telescopic shaft of the servo cylinder 315 is in the retracted state, and the rubber scraper 314 is located outside the gap of the lower roller 24. When the cardboard passes through, the telescopic shaft of the servo cylinder 315 extends horizontally, pushing the rubber scraper 314 to move towards the side wall of the cardboard until the rubber scraper 314 contacts the side walls of the cardboard. As the cardboard continues to move, the rubber scraper 314 scrapes away the glue that overflows from the edge of the cardboard during the lamination process, preventing glue from contaminating the side of the cardboard or other parts of the equipment.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
