Description

Technical Field

[0001] This utility model relates to the field of plant fiber pillow production technology, and in particular to a production device for a fully wrapped plant fiber pillow. Background Technology

[0002] Plant fiber pillows refer to pillows made from plant fiber materials such as palm fiber, oil palm fiber, hemp fiber, bamboo fiber, and coconut fiber. When our company makes mattresses from palm fiber, the process involves steaming, crushing, splitting, separating, polishing, drying, sifting, rope making, and bundling to obtain palm rope. After unraveling the palm rope, curled plant fiber filaments are obtained. These are then processed into plant fiber sheets, sprayed with adhesive, stacked, hot-pressed, and vulcanized to achieve the desired plant fiber mattress. However, there is limited technology available for plant fiber pillows. Chinese patent CN202619121U discloses a plant fiber health pillow, comprising: a plant fiber pillow core composed of randomly arranged plant fibers in a three-dimensional spatial network structure; and a pillowcase, removably wrapped around the outer surface of the plant fiber pillow core. This plant fiber health pillow is elastic, breathable, and effectively dissipates excess heat from the head, maintaining a dry feeling. The manufacturing process of this type of pillow leaves the rough edges intact. Because the plant fiber strands are relatively stiff, even with a pillowcase, the comfort will be affected. Moreover, when making an ergonomic pillow, the plant fibers inside the pillow are not evenly distributed, which affects the support effect. Summary of the Invention

[0003] The purpose of this invention is to provide a production device for a fully enclosed plant fiber pillow. This device is used to produce plant fiber pillows with a smooth surface, uniform internal plant fiber distribution, and better stress distribution.

[0004] The technical solution of this utility model is as follows: A production device for a fully wrapped plant fiber pillow includes a platform, a lower mold on the platform, a heating chamber connected below the lower mold, the heating chamber being connected to a heating pipe, a support above the platform, and an upper mold connected to the support via a telescopic mechanism. The upper mold and the lower mold together form a pillow mold.

[0005] The bracket has a rotating shaft in the middle, a motor is connected below the rotating shaft, a rotating arm is connected above the rotating shaft, and a telescopic mechanism is connected to the outside of the rotating arm.

[0006] Two rotating arms are provided symmetrically about the axis of rotation, and a telescopic mechanism is connected to the outer side of each rotating arm.

[0007] A deep groove ball bearing is provided at the connection between the lower part of the shaft and the platform.

[0008] A tapered roller bearing is provided at the connection between the upper part of the rotating shaft and the rotating arm.

[0009] The heating pipe is connected to the fan and heating equipment via a pipe.

[0010] A valve is installed on the pipe between the heating pipe and the heating equipment.

[0011] The lower mold has through holes evenly distributed inside.

[0012] The beneficial effects of this invention are as follows: This invention uses upper and lower molds to heat-press plant fiber elastic sheets into a pillow with the internal shape of the mold. A wrapping sheet can be laid at the bottom of the lower mold to enclose the plant fiber elastic sheets filled inside the mold, ensuring the pillow surface is covered by a single, complete plant fiber elastic sheet, preventing the plant fibers from being exposed. Compared with existing technologies, this invention has a simpler structure, produces a smoother pillow surface, more uniformly distributed internal plant fibers, and better stress resistance.

[0018] The present invention will be further described below with reference to the embodiments, but this should not be construed as limiting the present invention.

[0019] Example 1. A production device for a fully wrapped plant fiber pillow includes a platform 1, a lower mold 2 on the platform 1, a heating chamber 3 connected below the lower mold 2, the heating chamber 3 being connected to a heating pipe 4, a support 5 above the platform 1, and an upper mold 7 connected to the support 5 via a telescopic mechanism 6. The upper mold 7 and the lower mold 2 together form a pillow mold. The telescopic mechanism 6 can be an existing component such as a cylinder, hydraulic cylinder, or telescopic motor.

[0020] The bracket 5 has a rotating shaft 8 in the middle, a motor 9 connected below the rotating shaft 8, a rotating arm 10 connected above the rotating shaft 8, and a telescopic mechanism 6 connected to the outer side of the rotating arm 10. The rotating shaft 8 and the rotating arm 10 allow the telescopic mechanism 6 and the upper mold 7 to be rotated away from the lower mold 2, facilitating the inspection and replacement of parts.

[0021] Two rotating arms 10 are symmetrically arranged around the pivot 8. The outer side of each rotating arm 10 is connected to the telescopic mechanism 6. The symmetrically arranged rotating arms 10 can maintain the balance of the center of gravity and can also be used as spare upper molds 7, or equipped with upper molds 7 of different shapes.

[0022] A deep groove ball bearing 14 is provided at the lower part of the rotating shaft 8 where it connects to the platform 1. A tapered roller bearing 15 is provided at the upper part of the rotating shaft 8 where it connects to the rotating arm 10. The use of upper and lower bearings makes the rotation smoother.

[0023] The heating pipe 4 is connected to the fan 11 and the heating equipment 12 through the pipe, which can provide hot air during the mold pressing process, so that the pillow can be shaped faster and better.

[0024] A valve 13 is installed on the pipe between the heating pipe 4 and the heating device 12, which can control the amount of hot air.

[0025] The lower mold 2 has through holes evenly distributed to facilitate the introduction of hot air.

[0026] The usage process is as follows:

[0027] S1. The plant fiber filaments are made into ropes and unwound to obtain curled plant fiber filaments. After being made into sheets, they are sprayed with adhesive to obtain plant fiber elastic sheets. The plant fiber elastic sheets are cut according to the design dimensions to obtain wrapping sheets, filling sheets and bottom sheets.

[0028] S2, such as Figure 4 As shown, the wrapping sheet is laid out on the lower mold 2 of the platform 1, with the wrapping sheet extending to the outside of the lower mold 2. The telescopic mechanism 6 is activated to press the upper mold 7 down onto the lower mold 2, initially pressing the wrapping sheet into shape. Then the upper mold 7 is retracted, and the filling sheet is manually inserted into the wrapping sheet.

[0029] S3. Fold the portion of the wrapping sheet that remains outside the lower mold 2 into the lower mold 2. Press the upper mold 7 down onto the lower mold 2 again to shape the wrapping sheet and the internal filling sheet. Then retract the upper mold 7 and cover the filling sheet and wrapping sheet with the bottom sheet. Press the upper mold 7 down again to press the wrapping sheet and the bottom sheet together. The pillow is then shaped a second time. The surface is wrapped with a complete plant fiber elastic sheet to prevent the plant fiber strands from being exposed. There are only seams between the wrapping sheet and the bottom sheet.

[0030] When the pillow is designed with a curved shape, the two upper molds 7 connected to the rotating arm 10 have different shapes. One upper mold 7 is a curved mold with the same curved shape as the inner surface of the lower mold 2, and the other upper mold 7 is a flat mold. The initial pressing and forming of the wrapping sheet uses the curved mold, while the primary and secondary shaping uses the flat mold. This allows for the production of ergonomically designed curved pillows, such as... Figure 3 As shown.

[0031] Example 2. A production device for a fully wrapped plant fiber pillow includes a platform 1, a lower mold 2 on the platform 1, a heating chamber 3 connected below the lower mold 2, and a heating pipe 4 connected to the heating chamber 3. A support 5 is provided above the platform 1, and an upper mold 7 is connected to the support 5 via a telescopic mechanism 6. The upper mold 7 and the lower mold 2 together form a pillow mold. In this example, the support 5 is a fixed structure, connecting only one telescopic mechanism 6 and the upper mold 7. The telescopic mechanism 6 can be an existing component such as a cylinder, hydraulic cylinder, or telescopic motor.

[0032] The heating pipe 4 is connected to an existing hot air source through a pipe, which can provide hot air during the mold pressing process, so that the pillow can be shaped faster and better.

[0033] A valve 13 is installed on the pipe between the heating pipe 4 and the heating device 12, which can control the amount of hot air.

[0034] In use, the plant fiber filaments are made into ropes and unraveled to obtain curled plant fiber filaments. After being made into sheets, they are sprayed with adhesive to obtain plant fiber elastic sheets. The plant fiber elastic sheets are cut according to the design dimensions and stacked in the lower mold 2. Hot air is introduced into the lower mold 2, and the telescopic mechanism 6 is activated to press the upper mold 7 down to the lower mold 2. The pillow mold composed of the mold 7 and the lower mold 2 is used to compress and shape the filling sheet to obtain a regular rectangular plant fiber pillow.
