Description

Technical Field

[0001] The present invention belongs to the technical field of bamboo processing equipment, and particularly relates to a bamboo outer skin removing machine. Background Art

[0002] Bamboo products refer to products made from bamboo as raw materials for processing, mostly daily necessities, such as bamboo baskets, bamboo sieves, bamboo strainers, rice sieves, bamboo steamers, cooking brushes, bamboo dustpans, bamboo buckets, bamboo rakes, baskets, bamboo shoulder poles, bamboo chopsticks, bamboo brooms, bamboo hats, bamboo plaques, bamboo back baskets, bamboo mats, bamboo beds, bamboo stools, bamboo chairs, bamboo reclining chairs, chopping boards, cooling mats, tea cup pads, curtains, etc. When bamboo is used to make bamboo weaving utensils, such as bamboo steamers, after the bamboo is harvested and while it is still fresh and the bamboo skin is green, it is necessary to remove the bamboo joints and then promptly remove the green skin from the bamboo tube to facilitate weaving and processing.

[0003] The traditional methods for removing the green skin mainly include manual peeling and mechanical peeling. Among them, manual peeling has problems such as low efficiency and uneven peeling thickness, and it is easy to have over-peeling or missed peeling; the existing mechanical peeling is mainly ball milling and polishing type rolling peeling, that is, by rolling, the bamboo is in a rotating state, and at the same time, a relatively large pressure is applied to wear and remove the green skin on the outside of the bamboo. Since it is not along the fiber direction and rolls on the surface of the green skin, it is easy to damage the internal fibers, and at the same time, the bamboo tube is prone to bursting during rolling, especially in most parts of the south where most bamboos are relatively thin and not suitable for rolling.

[0020] The present invention discloses a bamboo peeling machine, which can peel the bamboo along the fiber direction of the bamboo, avoid damage to the internal fibers of the bamboo, and avoid bamboo bursting.

[0021] The technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0022] Referring to Figures 1 to 4 As shown, the present invention discloses a bamboo peeling machine for removing the outer skin of bamboo 11, which includes a machine base 17, a first support base 14, a second support base 2, a first limit block 1, a second limit block 33, a sliding seat 16, a sliding driving mechanism 19, and a pressing frame 6. The first support base 14 and the second support base 2 are spaced apart and arranged on the top of the machine base 17. The first support base 14 and the second support base 2 are used to support both sides of the bottom of the bamboo 11. The first support base 14 and the second support base 2 are in rolling contact with the bamboo 11. The first limit block 1 and the second limit block 33 are spaced apart and arranged on the top of the machine base 17. The first limit block 1 and the second limit block 33 are respectively located at both ends of the bamboo 11. The first limit block 1 and the second limit block 33 are used to limit both ends of the bamboo 11. The pressing frame 6 is arranged above the bamboo 11 so as to be displaceable up and down. When the pressing frame 6 presses down, it abuts against the top of the bamboo 11. A rotation driving mechanism 8 for driving the bamboo 11 to rotate along its circumferential direction is arranged on the pressing frame 6. The sliding seat 16 is slidably arranged along the axial direction of the bamboo 11 at the bottom of the bamboo 11. The sliding driving mechanism 19 is used to drive the sliding of the sliding seat 16. A tool assembly 15 is arranged on the top of the sliding seat 16. When the sliding seat 16 slides towards the bamboo 11, the tool assembly 15 is used to remove the outer skin of the bamboo 11.

[0023] When the bamboo peeling machine removes the green skin of the bamboo 11, the bamboo 11 can be placed between the first limit block 1 and the second limit block 33. The first limit block 1 and the second limit block 33 are used to prevent the axial movement of the bamboo 11. At the same time, the first support base 14 and the second support base 2 are used to support the bamboo 11. The pressing frame 6 is lowered to prevent the bamboo 11 from coming out. The sliding driving mechanism 19 is used to drive the sliding seat 16 to slide along the axial direction of the bamboo 11, so that the tool assembly 15 contacts the outer skin of the bamboo 11, and the green skin of the bamboo 11 is scraped off along the fiber direction of the bamboo 11, avoiding damage to the internal fibers of the bamboo 11. After the peeling is completed, the sliding seat 16 returns. The rotation driving mechanism 8 is used to drive the bamboo 11 to rotate a certain angle along its circumferential direction, and the peeling operation is repeated until the outer skin of the bamboo 11 is completely removed, effectively improving the efficiency of removing the outer skin of the bamboo 11. At the same time, no pressure needs to be applied to the bamboo 11, ensuring the integrity of the internal fibers of the bamboo 11.

[0024] Due to the inconsistent growth of the bamboo 11, there are also differences in the outer diameters of the bamboos 11 in the same batch. In order to avoid the problem of inconsistent peeling thickness caused by the difference in the gap between the tool assembly 15 and the bamboo 11, the inventor has improved the tool assembly 15 as follows:

[0025] The tool assembly 15 includes an elastic member 23, a tool holder 20, and a blade 21. The bottom of the tool holder 20 is connected to the top of the sliding seat 16 through the elastic member 23. One end of the tool holder 20 facing the bamboo 11 is an inclined surface. When the inclined surface abuts against the bamboo 11, the elastic member 23 is compressed by force, and the tool holder 20 descends to the bottom of the bamboo 11. The top surface of the tool holder 20 is a flat surface. A discharge port 22 penetrating through the tool holder 20 is formed at the top of the tool holder 20. The blade 21 is inclinedly arranged at the discharge port 22, and the cutting edge of the blade 21 faces the bamboo 11 and the cutting edge of the blade 21 is higher than the tool holder 20.

[0026] By setting one end of the tool holder 20 facing the bamboo 11 as an inclined surface and elastically connecting the tool holder 20 and the sliding seat 16, the descent of the tool holder 20 can be guided by the inclined surface, so that the height of the tool holder 20 can be adaptively adjusted during peeling, so that when peeling bamboos 11 with different outer diameters, the depth of the blade 21 cutting into the outer skin of the bamboo 11 is consistent, thus ensuring the consistency of the peeling thickness of bamboos 11 with different outer diameters.

[0027] The blade 21 is rotatably arranged on the tool holder 20. A fixing screw for fixing the rotation angle of the blade 21 is arranged on the tool holder 20. The peeling thickness is adjusted by adjusting the angle of the blade 21.

[0028] A strip-shaped hole 13 is provided at a position of the machine base 17 below the bamboo 11. A first slide rail 18 and a second slide rail 9 are provided on the top of the machine base 17.

[0029] When the first positioning screw 25 is screwed into the first positioning hole, the first support base 14 is fixed on the first slide rail 18. When the second positioning screw is screwed into the second positioning hole, the second support base 2 is fixed on the second slide rail 9. By contacting the outer wall of the bamboo 11 with the first roller 26, the second roller 27, the third roller and the fourth roller, the rotation of the bamboo 11 between the first support base 14 and the second support base 2 can be ensured.

[0030] The number of the first support bases 14 and the second support bases 2 is multiple. The multiple first support bases 14 are arranged at intervals on the first slide rail 18, and the multiple second support bases 2 are arranged at intervals on the second slide rail 9 to ensure the balance of the support effect.
