Description

Technical Field

[0001] This utility model relates to the field of honeycomb paperboard production technology, and in particular to a multi-layer composite honeycomb paperboard forming device. Background Technology

[0002] Honeycomb paperboard, as a lightweight, high-strength, and environmentally friendly material, is widely used in packaging, construction, and other fields. Its forming process typically involves the lamination, gluing, and compression molding of multiple layers of raw paper. Traditional honeycomb paperboard forming equipment uses mechanical transmission to transport, glue, and laminate the raw paper; however, its adaptability to different paperboard specifications remains limited, especially in the handling of thin raw paper and the precise control of glue thickness, which urgently needs optimization.

[0003] In existing technologies, honeycomb paperboard forming devices typically employ a feeding roller assembly and a gluing mechanism. The feeding section uses a motor-driven roller shaft to rotate, utilizing the friction between the feeding roller and the raw paper to pull the paper forward. The gluing section uses a transfer roller to pick up glue from a glue tank and transfer it to an upper glue roller, which then applies the glue to the surface of the raw paper. The glued raw paper is then laminated layer by layer by pressure rollers, cut and stacked, and then the paper core is stretched into a honeycomb structure by a tensioning structure. Finally, the face paper is attached, and the honeycomb paperboard is formed. This mechanical structure relies on constant pressure feeding and fixed-gap gluing, which, while meeting basic production needs, lacks adjustability when handling paper materials of different thicknesses.

[0004] However, existing technologies have the following problems: Traditional honeycomb paperboard forming devices use a fixed feeding force, which causes different specifications of raw material paper, especially thinner raw material paper, to easily break during the conveying process due to excessive force, affecting production efficiency and finished product quality. In addition, the glue transfer amount of the gluing mechanism cannot be precisely adjusted, making it difficult to adapt to the differentiated glue layer thickness requirements of different honeycomb paperboards. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-layer composite honeycomb paperboard forming device, which aims to improve the problem that traditional multi-layer composite honeycomb paperboard cannot control the tension of the raw material paper during feeding, resulting in the thinner raw material paper being prone to breakage during feeding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer composite honeycomb paperboard forming device, comprising a support column, a cross frame fixedly connected to the top of the support column, and a tensioning component provided on the top of the cross frame; The tensioning assembly includes a second bracket, the bottom of which is fixedly connected to the top of the crossbeam. A second motor is fixedly connected to the outer wall of the second bracket, and a first fixing block is fixedly connected to the output end of the second motor. One end of the first fixing block is rotatably connected inside the second bracket, and an adjusting roller is fixedly connected to the outer wall of the first fixing block.

[0007] As a further description of the above technical solution: A winch motor is fixedly connected to one end of the support column, and a feeding roller is fixedly connected to the output end of the winch motor.

[0008] As a further description of the above technical solution: A bracket is fixedly connected to the top of the cross frame, a limiting roller is rotatably connected to the outer wall of the bracket, and a limiting ring is fixedly connected to the outer wall of the limiting roller.

[0009] As a further description of the above technical solution: A bracket three is fixedly connected to the top of the cross frame, and a limit roller two is rotatably connected to the outer wall of the bracket three. A tensioning assembly is provided at the bottom of the cross frame.

[0010] As a further description of the above technical solution: A support plate is provided on one side of the cross frame. A motor is fixedly connected to the outer wall of the support plate. A glue transfer roller is fixedly connected to the output end of the motor. One end of the glue transfer roller is rotatably connected to the inside of the support plate.

[0011] As a further description of the above technical solution: A glue storage tank is fixedly connected to the inner wall of the support plate, a fixing block is fixedly connected to the inner wall of the support plate, a glue storage tank is fixedly connected to one end of the fixing block, a motor is fixedly connected to the outer wall of the support plate, a scraper is fixedly connected to the output end of the motor, one end of the scraper is rotatably connected to the inside of the support plate, and a limit ring is fixedly connected to the outer wall of the scraper.

[0012] As a further description of the above technical solution: The bottom of the glue storage tank 2 is fixedly connected to a glue flow channel, and one end of the glue flow channel is fixedly connected to the inside of the glue storage tank 1.

[0013] As a further description of the above technical solution: A rolling mill is installed on one side of the support plate. A limiting roller group is installed on one side of the rolling mill. A dryer is installed on one side of the limiting roller group. A gluing machine is installed on one side of the dryer. A cross-cutting machine is installed on one side of the gluing machine. A tensioning machine is installed on one side of the cross-cutting machine. A rolling mill is installed on one side of the tensioning machine. A dryer is installed on one side of the rolling mill. A cooler is installed on one side of the dryer. A cross-cutting machine is installed on one side of the cooler.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a second bracket is first fixed at the top of the cross frame. Between the second bracket, a second motor controls the rotation of a first fixing block, which in turn controls the rotation of an adjusting roller fixed on the outside of the first fixing block. Since different thicknesses of raw paper are required to make honeycomb paperboard of different specifications, using a fixed feeding force will cause different internal forces to be received by raw paper of different specifications, especially thinner paper may break. By passing the raw paper through the first fixing block, the tension of the raw paper can be controlled by adjusting the angle of the first fixing block. This solves the problem that traditional honeycomb paperboard forming devices cannot adjust the tension of the raw paper, which leads to the breakage of thinner paper. This improves the practicality of the multi-layer composite honeycomb paperboard forming device.

[0015] 2. In this utility model, when applying glue to the raw paper, the glue transfer roller transfers the glue in the glue storage tank to the surface of the glue coating roller through contact. The glue coating roller then applies the glue to the surface of the raw paper through contact with the raw paper. However, different specifications of honeycomb paperboard require different glue thicknesses when applying glue to the raw paper. A scraper is provided below the glue coating roller, and the distance between the scraper and the glue coating roller is controlled by the motor. The scraped glue is collected by the glue storage tank and flows back to the glue storage tank through the glue flow channel. This achieves control over the thickness of the glue applied to the raw paper, solves the problem that traditional honeycomb paperboard cannot control the thickness of the glue applied, and improves the economy of the multi-layer composite honeycomb paperboard forming device.

[0021] Working principle: The feeding roller 7 is controlled by the hoisting motor 6 to rotate and transport the raw paper to the forming device.

[0023] After applying an appropriate amount of glue, the multi-layered raw paper is laminated together by a roller press 25. Then, it is limited by a set of limiting rollers 26 and enters a dryer 27 for drying. Next, a gluing machine 28 applies glue to the surface of the laminated paper core. Then, a cross-cutting machine 29 slices and presses the paper core together. The tensioning machine 30 opens the paper core and attaches face paper to both sides.
