Description

Technical Field

[0001] This utility model relates to the field of bamboo fiberboard technology, specifically a hot press for bamboo fiber felt composite boards. Background Technology

[0002] Bamboo fiber, as a natural, biodegradable biomass material with excellent mechanical properties, has shown great application potential in the field of environmentally friendly composite materials. Fiber mats made from bamboo fiber, when combined with resin and subjected to hot pressing, can produce high-strength, lightweight, and environmentally friendly composite boards, which are widely used in construction, home furnishings, and automotive interiors.

[0003] Hot pressing is the core process in manufacturing bamboo fiber felt composite boards, which directly determines the final mechanical properties, density distribution and molding quality of the boards. Currently, the existing technology generally uses ordinary flat plate hot presses. This type of equipment heats and presses the blank containing bamboo fiber felt and resin through an electric heating plate, so that the resin melts and impregnates the fibers, and finally solidifies and forms the board.

[0004] However, existing hot pressing processes and equipment have the following significant drawbacks: Limited functionality and poor adaptability: Traditional hot presses typically only perform a single dry hot pressing process. For certain resin systems requiring steam-assisted heating or blanks demanding higher penetration effects, existing equipment cannot perform steam hot pressing, limiting its process adaptability and further improvement of sheet performance. Steam hot pressing can effectively soften fibers, improve resin flowability and penetration depth, thereby enhancing the interfacial bonding between fibers and resin, and is one of the key processes for improving the quality of high-end composite materials.

[0005] The effectiveness and efficiency of hot pressing need improvement: Relying solely on the hot press plate to conduct heat from the upper and lower surfaces can easily lead to uneven heat conduction, slow core layer heating, and asynchronous resin curing in blanks of a certain thickness. This can result in uneven internal stress in the sheet, or even delamination or deformation. Furthermore, moisture and volatiles in the sheet are difficult to remove quickly after hot pressing, prolonging the curing and cooling time and reducing production efficiency.

[0006] Low efficiency in handling composite panels: The formed composite panels are usually at high temperatures and are large in size. Most existing equipment requires operators to manually pry and move them with tools, which is not only labor-intensive and inefficient, but also poses a risk of burns from high temperatures and can easily damage the edges of the panels during handling.

[0007] Insufficient clamping stability: During the hot pressing process, especially when steam is injected, the billet may undergo slight displacement or deformation due to thermal expansion or steam pressure. If there is no effective clamping and stabilizing mechanism on all four sides, it is very easy to cause quality problems such as uneven edges and uneven thickness of the finished sheet.

[0008] Therefore, there is an urgent need in this field for a new type of hot pressing equipment that integrates conventional hot pressing and steam hot pressing, can significantly improve the hot pressing effect and efficiency, and can achieve automated and efficient plate collection, so as to solve the defects existing in the above-mentioned prior art.

The adjustment slot 41 has a T-shaped cross-section, and a T-shaped slider is slidably installed in each adjustment slot 41. The four clamping slide plates 42 are respectively fixedly connected to the four T-shaped sliders by screws. The two can be disassembled, so that the thickness of the clamping slide plate 42 can be changed according to the thickness of the wood board. It should be noted that the thickness of the clamping slide plate 42 needs to be lower than the thickness of the wood board. The T-shaped slider has a threaded hole in the middle. A screw motor 43 for driving the movement of the corresponding T-shaped slider is fixedly installed on the outside of the plate bearing platform 4.

[0031] In this embodiment, the upper surface of the plate bearing platform 4 is provided with sliding grooves 44 extending toward the plate storage area 7 on both sides. Multiple rollers 45 are evenly rotatably installed in the sliding grooves 44. The two side walls of the sliding grooves 44 are vertically provided with sliding slots 441 at the positions of the rollers 45. Bearings are provided in the sliding slots 441. The rotating shafts at both ends of the rollers 45 are inserted into the corresponding bearings.

[0032] In this embodiment, the hot steam pipe 34 and the air outlet pipe 35 are respectively connected to an external hot steam source and an air pump via flexible hoses.

[0033] In this embodiment, rectangular slots 15 are provided at both ends of the upper part of the bearing box 1. The lifting support mechanism 5 includes two rectangular support plates 55, which are inserted into the rectangular slots 15. A diagonal tie rod 51 is movably hinged to the lower end of the rectangular support plate 55. A device cavity 12 communicating with the two rectangular slots 15 is provided horizontally inside the bearing box 1. Guide rails 53 are fixedly installed at both ends of the top of the device cavity 12. A slide block 54 is slidably installed on the guide rail 53.

The piston rod of the hydraulic rod 52 is fixedly connected to the corresponding slide block 54.

[0034] Furthermore, in this embodiment, two feeding plates are fixedly installed on one side of the board bearing platform 4 near the board storage area 7. The two feeding plates are located on both sides of the corresponding lead screw motor 43. Multiple feeding rollers 46 are rotatably installed on the feeding plates, which can effectively prevent the board from hitting the lead screw motor 43 when it slides.

[0035] The aforementioned electrical equipment and components can be controlled via a remote controller or a switch installed on the carrier housing 1.

[0036] The specific operating steps are as follows: Place the wooden board on the carrier box 1, and drive the clamping slide plate 42 to move by starting the screw motor 43. The four clamping slide plates 42 can stably clamp the four sides of the wooden board. Then, place the bamboo fiber felt on the wooden board and start the press machine 21. The press machine 21 drives the gas pressing plate 31 to move downward. The hot press plate 8 at the bottom can perform preliminary hot pressing on the bamboo fiber felt under the heating action of the heating pipe 84, thereby melting the resin in the felt and hot pressing it onto the surface of the wooden board, thus hot pressing the two into a composite board. After hot pressing, the linear guide 9 is activated, which drives the suspension plate 91 to approach the hot pressing plate 8. When the top rod 921 is inserted into the locking hole 811, the electric push rod 93 is activated. The electric push rod 93 pushes the force plate 101 to squeeze the locking block 102 downward, so that the locking block 102 is inserted into the insertion hole 922. The linear guide 9 is controlled to move the suspension plate 91 outward. At this time, the hot pressing plate 8 can be separated from the gas pressing plate 31, so that the bottom of the gas pressing plate 31 is completely exposed. Then, the press 21 controls the gas pressing plate 31 to move downward. Hot steam is injected into the gas pressing plate 31 through the external hot steam generator. The hot steam is blown to the surface of the bamboo fiber felt through the air hole for auxiliary heat conduction, which further improves the hot pressing effect. After the steam hot pressing has been performed for a certain period of time, the air pump is activated. The air pump can discharge the water vapor on the surface of the bamboo fiber felt through the air outlet pipe 35, so that the composite board can be formed quickly. The gas pressing plate 31 detaches from the surface of the board, and the roller 45 is lifted by the elastic force of the disc spring 442, so that the formed board can be lifted. At this time, the hydraulic rod 52 retracts, which will pull the diagonal rod 51 to put the rectangular support plate 55 into the rectangular slot 15. At this time, the top-overturning cylinder 6 can lift and flip one end of the board bearing platform 4, and the composite board can slide to the board storage area 7.

[0037] 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.
