Description

Technical Field

[0001] This utility model relates to the field of bamboo processing equipment, and in particular to a bamboo decomposition equipment for preparing bamboo fiber nonwoven fabric raw materials. Background Technology

[0002] Bamboo decomposition is a key step in the manufacture of bamboo fiber nonwoven fabrics. Its main purpose is to break down the intercellular layer and cell walls of bamboo through mechanical or chemical means, thereby increasing the material's permeability and bonding properties. This process is crucial for improving bamboo utilization and the physical and mechanical properties of the reconstituted material. Specifically, the treated bamboo fiber bundles, while maintaining longitudinal strength, can form multi-scale interfaces through bonding, which significantly enhances the flexural strength, tensile strength, and compressive strength of the reconstituted material.

[0003] Although direct crushing and defragmentation technology performs excellently in improving bamboo utilization, there are still some problems to be solved in actual operation. For example, when using crushing equipment to crush bamboo, a method similar to directly crushing bamboo with crushing rollers is used. Therefore, a lot of bamboo shavings remain on the defragmented bamboo fibers during the process. If these residual bamboo shavings are discharged directly, they will negatively affect subsequent processing steps, increasing the difficulty and cost of subsequent processing. Therefore, it is necessary to design a bamboo defragmentation device for the preparation of bamboo fiber nonwoven fabric raw materials to remove these residual bamboo shavings, so as to ensure the quality of bamboo fibers and simplify the subsequent processing procedures.

Detailed Implementation

[0020] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0021] A bamboo decomposition device for preparing bamboo fiber nonwoven fabric raw materials, such as Figures 1-4 As shown, the device includes a support frame 1, a mounting frame 2, and pressing rollers 3. The support frame 1 serves as the assembly carrier for the equipment. The mounting frame 2 is fixedly mounted on the support frame 1. Two sets of pressing rollers 3 are symmetrically mounted on both sides of the mounting frame 2 via electric drive. Each set of pressing rollers 3 has two rollers, symmetrically distributed vertically. The pressing rollers 3 are used to press and loosen bamboo. The device also includes mounting plates 4 fixedly connected to the outer walls of the front and rear sides of the mounting frame 2. A mounting frame 5 is fixedly installed between the mounting plates 4 on both sides of the mounting frame 2. The mounting frame 5 is located between the pressing rollers 3 on both sides. Pulleys 6 are rotatably mounted on each mounting plate 4. A circular drive belt 7 is wound between the two pulleys 6 on both sides. The drive belt 7 slides through the side wall of the mounting frame 2. The mounting frame 5 is slidably supported on the inside of the drive belt 7. A motor 8 is fixedly mounted on one side of the mounting plate 4. The output shaft of machine 8 is connected to the shaft 12 of the corresponding pulley 6. Fixing plates 9 are fixedly mounted on the upper and lower belts of drive belt 7. Fans 10 are fixedly mounted on both sides of the outer wall of mounting frame 2. Fans 10 are connected to the fixing plates 9 at the upper and lower positions through air ducts 11. The air outlets of air ducts 11 face the inner side of mounting frame 5 on the fixing plates 9. Bamboo is placed between two rolling rollers 3 on the same side for rolling and loosening. When the loosened bamboo passes through mounting frame 5, the fixing plates 9 on the upper and lower sides of drive belt 7 are moved back and forth in mounting frame 2 by motor 8. Airflow is blown into air ducts 11 by fans 10. The blown airflow is blown from air ducts 11 on fixing plates 9 to the loosened bamboo, thereby cleaning the residual bamboo chips on the loosened bamboo and avoiding negative impact on subsequent processing steps.

[0022] like Figure 4 As shown, two sets of limiting plates 13 are rotatably connected between the inner walls of the mounting frame 2 via a rotating shaft 12. The limiting plates 13 are located between the two side rolling rollers 3. Each set of limiting plates 13 consists of two symmetrical pieces, one above the other. The limiting plates 13 are distributed on both sides of the air duct 11. A torsion spring 14 is provided between the rotating shaft 12 of the limiting plate 13 and the mounting frame 2. Under the action of the torsion spring 14, the limiting plates 13 in the same set are inclined and press against each other. The inclined openings of the limiting plates 13 in the same set face the bamboo feeding direction. The limiting plates 13 are used to block the bamboo chips blown out of the air duct 11 from splashing to the outside of the mounting frame 2.

[0023] like Figure 4 As shown, clamping wheels 15 are rotatably installed on the ends of the limiting plates 13 that press against each other. The clamping wheels 15 roll in contact with the loosened bamboo, so that the limiting plates 13 can guide the bamboo to be transported normally.

[0024] like Figure 2 As shown, a guide frame 16 is mounted on the inlet / outlet side of the support frame 1. A roller for conveying bamboo is rotatably mounted on the guide frame 16 to improve the efficiency of bamboo conveying.

[0025] like Figure 3 As shown, the inner walls of the mounting frame 2 are symmetrically connected with limiting frames 17 on both sides. The limiting frames 17 are located on the upper and lower sides of the drive belt 7. The limiting frames 17 have grooves. The fixing plate 9 slides in the grooves of the corresponding limiting frames 17. The limiting frames 17 are used to smoothly guide the air duct 11 on the fixing plate 9 and improve the stability of the air duct 11 blowing air to clean bamboo debris.

[0026] like Figure 3 As shown, a central frame 18 is fixedly installed at the bottom inside the mounting frame 2. The central frame 18 is a downward-facing concave bucket-shaped frame. The central frame 18 is used to centrally guide and collect the bamboo shavings that have been cleaned.

[0027] Bamboo is first fed into the feed end of the support frame 1 and guided by the rollers on the guide frame 16 into the space between the first set of symmetrically arranged crushing rollers 3. Driven by the motor 8, the crushing rollers 3 rotate in opposite directions, applying compression and shearing forces to the bamboo, initially loosening its fiber structure. After this initial crushing, the bamboo continues to be conveyed forward into the second set of crushing rollers 3 for secondary crushing, ensuring thorough breaking down into fibrous raw materials suitable for subsequent processing. During transport, the loosened bamboo passes through the area of ​​the mounting frame 5. At this time, the motor 8 drives the pulley 6 to rotate, causing the annular drive belt 7 to circulate within the mounting frame 2. The fixing plates 9, fixed to the upper and lower sides of the belt, move back and forth accordingly. Simultaneously, the fan 10 starts, delivering high-speed airflow to the fixing plates 9 through the air duct 11. The airflow is ejected from the air outlets on the fixing plates 9, directly acting on the bamboo. On the surface of the material, the fine bamboo shavings attached to the fibers are blown away. To prevent the bamboo shavings blown away by the airflow from splashing everywhere, a rotatable limiting plate 13 is set in the mounting frame 2. The limiting plate 13 is kept in an inclined and closed state under the action of the torsion spring 14, and the bamboo material is gently clamped by the clamping wheel 15 at the end. This ensures that the bamboo material passes through smoothly and prevents the bamboo shavings from spreading outward. The bamboo shavings stripped by the airflow settle downward under the guidance of the limiting plate 13 and finally fall into the collection frame 18 for collection, which is convenient for subsequent cleaning. The cleaned bamboo fibers are output from the discharge end of the support frame 1 and enter the next processing step. In the whole process, the rolling roller 3, the airflow cleaning mechanism and the limiting and guiding structure work together to achieve efficient stripping and cleaning of the bamboo material, effectively reduce the impact of residual bamboo shavings on subsequent processes and improve the preparation quality of bamboo fiber nonwoven fabric raw materials.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
