Description

Technical Field

[0001] This utility model relates to the field of plant fiber mattress production technology, and in particular to an online hot pressing device for plant fiber elastic materials. Background Technology

[0002] Plant fiber mattresses refer to mattresses made from plant fiber materials such as palm, oil palm, hemp, bamboo fiber, and coconut shell fiber. Chinese Patent 201510910886.8 discloses a pre-compression molding equipment and method for producing plant fiber mattresses. The equipment includes a pre-compression frame (1), a conveyor roller (2) on the pre-compression frame (1), a conveyor belt (3) connected to the conveyor roller (2), at least two pre-compression rollers above one end of the conveyor belt (3), and the two ends of the pre-compression rollers are connected to the columns (11) on both sides of the pre-compression frame (1). The axis of one of the pre-compression rollers is located in the same vertical plane as the axis of the conveyor roller (3) directly below it. A pre-compression belt (8) is connected to the pre-compression roller. The method involves conveying the semi-finished plant fiber mattress to the pre-compression belt (8) and the conveyor belt (3) via the conveyor belt (3), where it is pre-compressed under the mutual pressure of the pre-compression roller and the conveyor roller (2).

[0003] This technology only pre-compresses the plant fiber elastic material, but it still uses a traditional hot press for hot pressing. During the hot pressing process, there is a lot of lifting and handling, which is labor-intensive and can cause quality problems such as deformation and breakage of the plant fiber elastic material. In addition, the hot pressing process relies on heat conduction to slowly penetrate and shape the material, resulting in low hot pressing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an online hot pressing device for plant fiber elastic materials, thereby improving the efficiency of hot pressing and reducing manual handling.

[0005] The technical solution of this utility model is as follows: an online hot pressing device for plant fiber elastic materials, including a pre-pressing device and an online hot press. The pre-pressing device is equipped with an inclined pre-pressing upper conveyor belt, and the online hot press includes a forming conveyor belt connected to the pre-pressing device. The outside of the online hot press is equipped with a heat insulation layer, and the online hot press is also connected to a heating system.

[0006] The forming conveyor belt includes an upper conveyor belt and a lower conveyor belt, with the lower conveyor belt being connected at the same height as the pre-compression lower conveyor belt of the pre-compression equipment.

[0007] The upper conveyor belt is connected to a lifting mechanism.

[0008] The online hot press is equipped with an external insulation layer.

[0009] The pre-compressed upper conveyor belt is connected to a lifting mechanism.

[0010] The heating system includes heating equipment, which is connected to a fan.

[0011] The beneficial effects of this invention are as follows: The plant fiber elastic sheet of this invention, after pre-compression, can directly enter an online hot press for hot pressing. After hot pressing, it is automatically conveyed to the next process. Under the action of a large air compressor, the hot air of the online hot press is forced to penetrate into the interior of the elastic material, achieving rapid hot pressing and shaping. Compared with the prior art, this invention has the advantages of reducing manual handling, high hot pressing and shaping efficiency, and reducing breakage quality problems. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0013] The present invention will be further described below with reference to the embodiments, but this should not be construed as limiting the present invention.

[0014] Example 1. An online hot pressing device for plant fiber elastic materials includes a pre-pressing device 1 and an online hot press 2. The pre-pressing device 1 is equipped with an inclined pre-pressing upper conveyor belt 5. The online hot press 2 includes a forming conveyor belt connected to the pre-pressing device 1. The outside of the online hot press 2 is provided with a heat insulation layer 8. The online hot press 2 is also connected to a heating system.

[0015] The forming conveyor belt includes an upper conveyor belt 3 and a lower conveyor belt 4, with the lower conveyor belt 4 being connected at the same height to the pre-compression lower conveyor belt 10 of the pre-compression equipment 1. The upper conveyor belt 3 and the lower conveyor belt 4 can adopt existing structures such as rollers, belts, and tracks.

[0016] The upper conveyor belt 3 is connected to the lifting mechanism 6. The lifting mechanism 6 can be implemented using mechanisms such as worm gear mechanism, motor, cylinder and hydraulic cylinder.

[0017] The online hot press 2 is provided with an insulation layer 8.

[0018] The pre-compression upper conveyor belt 5 is connected to the lifting mechanism 6, which controls the lifting of the pre-compression upper conveyor belt 5 to adjust the height of the pre-compression elastic material.

[0019] The heating system includes a heating device 9, which is connected to a fan 7.

[0020] The working principle involves stacking multiple layers of plant fiber elastic sheets, feeding the stacked plant fiber elastic sheets into a pre-compression device 1, pre-compressing them to a predetermined thickness, and then feeding them into an online hot press 2. The plant fiber elastic sheets are squeezed up and down by a forming conveyor belt and hot-pressed in the high-temperature environment of the online hot press 2 to obtain plant fiber elastic materials shaped to a standard thickness. Then, the materials are sent out of the hot press via a forming conveyor belt.

[0021] The setting time and effect of plant fiber elastic materials are controlled by adjusting the conveyor speed of the forming conveyor belt. Different conveyor speeds, i.e., different hot pressing times, are used for materials of different thicknesses to achieve the desired hot pressing setting effect.

[0022] The shaping thickness of plant fiber elastic materials is controlled by adjusting the height of the forming conveyor belt.

[0023] The pre-compression thickness of the plant fiber elastic material is controlled by adjusting the height of the outlet of the pre-compression device 1. The height of the outlet of the pre-compression device 1 is less than or equal to the height of the compression conveyor belt. The height of the outlet of the pre-compression device 1 can be adjusted by raising and lowering the upper pre-compression conveyor belt 5.

[0024] The forming conveyor belt includes an upper conveyor belt 3 and a lower conveyor belt 4, which can adopt existing structures such as rollers, belts, and tracks. The upper conveyor belt 3 is connected to a lifting mechanism 6, which controls the lifting of the upper conveyor belt 3 to adjust the height of the forming conveyor belt.

[0025] The online hot press 2 adjusts the shaping temperature of the plant fiber elastic material through a heating system. The heating system includes a heating device 9, which is connected to a fan 7. An insulation layer 8 is installed on the outside of the online hot press 2 to reduce energy consumption.

[0026] Example 2. An online hot pressing device for plant fiber elastic materials includes a pre-pressing device 1 and an online hot press 2. The pre-pressing device 1 is equipped with an inclined pre-pressing upper conveyor belt 5. The online hot press 2 includes a forming conveyor belt connected to the pre-pressing device 1. The outside of the online hot press 2 is provided with a heat insulation layer 8. The online hot press 2 is also connected to a heating system.

[0027] The forming conveyor belt includes an upper conveyor belt 3 and a lower conveyor belt 4, with the lower conveyor belt 4 being connected at the same height to the pre-compression lower conveyor belt 10 of the pre-compression equipment 1. The upper conveyor belt 3 and the lower conveyor belt 4 can adopt existing structures such as rollers, belts, and tracks.

[0028] The online hot press 2 is provided with an insulation layer 8.

[0029] The heating system can use hot air from inside the workshop.

[0030] The working principle involves stacking multiple layers of plant fiber elastic sheets. The stacked sheets are then fed into a pre-compression device 1, where they are pre-compressed to a predetermined thickness. Afterward, they are fed into an online hot press 2, where a forming conveyor belt compresses the plant fiber elastic sheets. The hot press 2 utilizes its high-temperature environment to hot-press the material, resulting in a plant fiber elastic material of a standard thickness. This material is then conveyed out of the hot press via the forming conveyor belt. This embodiment is suitable for producing plant fiber elastic materials of a single model and fixed thickness.

[0031] The setting time and effect of plant fiber elastic materials can be controlled by adjusting the conveyor speed of the forming conveyor belt.

[0032] The height of the outlet of the pre-compression equipment 1 is less than or equal to the height of the forming conveyor belt, which facilitates the entry of the end of the plant fiber elastic sheet into the online hot press 2.

[0033] The forming conveyor belt includes an upper conveyor belt 3 and a lower conveyor belt 4, which can adopt existing structures such as rollers, belts, and tracks.
