Description
Technical Field
[0001] This utility model relates to the field of bamboo processing technology, and in particular to a bamboo filament separation and discharge device. Background Technology
[0002] Bamboo is abundant in my country and is environmentally friendly, so it is often used to process various bamboo products. During the production and processing of bamboo, the raw material needs to be processed into a velvety state through kneading and tearing to obtain intermediate raw materials such as bamboo fiber and bamboo powder.
[0003] Chinese patent CN201820974012.8 discloses a bamboo fiber splitting device, including a splitting box, cross cutter rollers, a feed inlet, a discharge outlet, a splitting motor, a reducer, a coupling, and a shaft support. A rotating shaft is mounted on the shaft support. Multiple splitting boxes are arranged in a ring array around the axis of the rotating shaft and are connected to the rotating shaft through connecting seats. Two cross cutter rollers are installed inside the splitting box, with one end connected to a cross cutter roller shaft. A transmission gear is mounted on the cross cutter roller shaft, and the rotating gears on the two cross cutter roller shafts mesh with each other. The output shaft of the splitting motor is connected to the cross cutter roller shaft through the reducer and the coupling.
[0004] Existing technologies employ a double-spiral grinding and splitting method, with the split material discharged via extrusion using the screw extruder's own conveying function. For the novel splitting structure that uses a non-spiral grinding method, an additional discharge structure is required to ensure timely output of the split material. Utility Model Content

The filament separation method involves a filament separation mechanism rotating within a filament separation drum to pound and grind the bamboo material inside. A multi-stage discharge mechanism is used to output the material via negative pressure adsorption. This method ensures that only fully filamentized lightweight bamboo material is smoothly discharged, while the remaining bamboo material continues to be filamentized within the drum until full filament separation is achieved. Furthermore, the multi-stage discharge mechanism in this invention combines conveying and screening functions, ensuring that the material is promptly screened and output after meeting the filament separation requirements, guaranteeing both filament separation and discharge efficiency.

[0010] Preferably, the second and third discharge mechanisms are both coaxially mounted on the wire splitting mechanism and rotate synchronously with the wire splitting mechanism.
[0011] Preferably, the first discharge mechanism includes: an induced draft fan; and a conveying pipe, one end of which is connected to the wire splitting drum and the other end of which is connected to the induced draft fan.
[0012] Preferably, a dust collection bag structure is also connected to the output path of the conveying pipe to collect the bamboo material output from the conveying pipe.

[0015] Preferably, the baffle A and the feeding section A are arranged alternately and evenly, and the coarse discharge port is formed between adjacent baffle A and feeding section A.
[0016] Preferably, the third discharge mechanism includes: a baffle B, a plurality of baffles B are spaced apart and arranged in a ring around the outer ring of the rotating shaft of the wire splitting mechanism, the subdivision discharge port is formed between adjacent baffles B, the working area is formed between the baffles B and the wire splitting cylinder, and the discharge area is formed between the baffles B and the rotating shaft.
[0017] Preferably, both the baffle A and the baffle B are configured as elongated strip structures.
[0018] Preferably, the third discharge mechanism further includes a feeding section B, which is circumferentially distributed on the rotating shaft and extends radially along the splitting cylinder. The side of the feeding section B facing the first discharge mechanism is configured as an arc surface with a narrower width, so that a relative positive pressure difference is formed in the splitting cylinder when the third discharge mechanism rotates.
[0019] Preferably, the wire splitting drum is arranged horizontally along its axis, with a feed inlet at its top away from the first discharge mechanism and a slag discharge outlet at its bottom near the first discharge mechanism.

[0021] The beneficial effects of this utility model are as follows:
[0022] (1) This utility model is for a method of splitting bamboo material by using a splitting mechanism to rotate inside a splitting cylinder to beat and grind the bamboo material inside the splitting cylinder. A multi-stage discharge mechanism is set inside the splitting cylinder and on the side of the cylinder. The discharge mechanism outputs the material by negative pressure adsorption.

[0023] (2) This utility model sets up a second discharge mechanism and a third discharge mechanism in the splitting cylinder. The second discharge mechanism divides the cylinder into a coarse splitting space and a fine splitting space, and the third discharge mechanism divides the fine splitting space into a working area and a discharge area.

The structure is ingenious and the practicality is strong.
[0024] (3) This utility model sets up feeding section A and feeding section B on the second and third discharge mechanisms. Feeding section A and feeding section B are provided with arc surfaces with narrow width. According to the principle of fluid mechanics, when the splitting mechanism rotates, the air pressure in the splitting space of the splitting tube is lower than the air pressure in the coarse splitting space, and the air pressure in the discharge area is lower than the air pressure in the working area, thereby forming a relative negative pressure difference. This promotes the output of fully split bamboo material under negative pressure. The mechanical structure assists the first discharge mechanism to discharge material, improves the output efficiency, and saves more energy. Attached Figure Description

[0034] In this embodiment, a splitting mechanism 2 is used to rotate inside a splitting cylinder 1 to beat and grind the bamboo material inside the cylinder 1. A first discharge mechanism 3 is sealed and connected to the side of the splitting cylinder 1. The first discharge mechanism 3 outputs the split material inside the splitting cylinder 1 by negative pressure adsorption. This method can ensure that only the lightweight bamboo material that has been fully split can be output smoothly, while the remaining bamboo material continues to be split inside the cylinder until the full splitting effect is achieved.
[0035] As a preferred option, such as Figure 2 As shown, it also includes: a second discharge mechanism 4, which is located in the middle of the axial direction of the splitting mechanism 2 and divides the inner cavity of the splitting cylinder 1 into a coarse splitting space 101 on the front side and a fine splitting space 102 on the rear side. The bamboo material is coarsely split and finely split in the coarse splitting space 101 and the fine splitting space 102 respectively. The second discharge mechanism 4 is provided with a coarse splitting discharge port 40 so that the bamboo material that has been coarsely split in the coarse splitting space 101 can pass through.
[0036] As a preferred option, such as Figure 2-3As shown, it also includes: a third discharge mechanism 5, which is located within the subdivision space 102 and is a cylindrical structure arranged along the inner ring of the wire splitting drum 1. It divides the subdivision space 102 into an outer annular working area 103 and an inner discharge area 104. The first discharge mechanism 3 is sealed and connected to the discharge area 104. Figure 4 As shown, the third discharge mechanism 5 is provided with a subdivision discharge port 50 for bamboo materials that have been subdivided within the working area 103 to pass through.
[0037] In this embodiment, by setting a second discharge mechanism 4 and a third discharge mechanism 5 inside the splitting cylinder 1, a multi-stage discharge mechanism is formed with the first discharge mechanism 3. The second discharge mechanism 4 divides the cylinder into a coarse splitting space 101 and a fine splitting space 102. The third discharge mechanism divides the fine splitting space into a working area 103 and a discharge area 104. After the bamboo material enters the splitting cylinder 1, it is first coarsely split in the coarse splitting space 101 and then finely split in the fine splitting space 102, thereby realizing the graded splitting of the material with a high degree of precision.
[0038] As a preferred option, such as Figure 5 As shown, the second discharge mechanism 4 includes: a mounting base 41, which is coaxially mounted on the rotating shaft 20 of the wire splitting mechanism 2; and a baffle A42, which is circumferentially spaced on the mounting base 41 and extends radially along the wire splitting cylinder 1, with the coarse discharge port 40 formed between adjacent baffles A42.
[0039] As a preferred option, such as Figure 3 As shown, the third discharge mechanism 5 includes: a baffle B51, a plurality of baffles B51 are spaced apart and arranged in a ring around the outer ring of the rotating shaft 20 of the wire splitting mechanism 2, the subdivided discharge port 50 is formed between adjacent baffles B51, the working area 103 is formed between the baffles B51 and the wire splitting cylinder 1, and the discharge area 104 is formed between the baffles B51 and the rotating shaft 20.
[0040] Correspondingly, baffles A42 and B51 are arranged in an array at intervals on the second discharge mechanism 4 and the third discharge mechanism 5, and coarse discharge port 40 and fine discharge port 50 are respectively provided. The bamboo material that passes the coarse separation is output to the fine discharge space 102 for fine separation through the coarse separation discharge port 40. The large-volume bamboo material that does not pass the fine separation is blocked by baffle A42 and remains in the coarse separation space 101 for coarse separation. The bamboo material that passes the fine separation in the working area 103 is output to the discharge area 104 through the fine separation discharge port 50, and then output and collected from the conveying pipe 32. The large-volume bamboo material that does not pass the fine separation is blocked by baffle B51 and remains in the working area 103 for fine separation. In this way, the graded output of materials is achieved in conjunction with the grading and fiber separation work.
[0041] The multi-stage discharge mechanism in this embodiment combines conveying and screening functions, enabling materials to be screened and output in a timely manner after reaching the fiber separation requirements, ensuring both fiber separation and discharge effects. The structure is ingenious and highly practical.
[0042] Preferably, both the stop A42 and the stop B51 are configured as elongated strip structures.
[0043] Preferably, the second discharge mechanism 4 and the third discharge mechanism 5 are both coaxially mounted on the wire splitting mechanism 2 and rotate synchronously with the wire splitting mechanism 2; the outer diameter of the second discharge mechanism 4 is adapted to the inner diameter of the wire splitting cylinder 1, the outer diameter of the third discharge mechanism 5 is smaller than the inner diameter of the wire splitting cylinder 1 to leave the working area 103, and the outer diameter of the third discharge mechanism 5 is adapted to the outer diameter of the mounting base 41 to prevent the bamboo material in the coarse splitting space 101 from directly entering the discharge area 104, and one end of the baffle B51 is mounted on the mounting base 41.
[0044] As a preferred option, such as Figure 1 As shown, the first discharge mechanism 3 includes: a blower 31; and a conveying pipe 32, one end of which is connected to the wire splitting cylinder 1, and the other end is connected to the blower 31.
[0045] Preferably, a dust collection bag structure is also connected to the output path of the conveying pipe 32 to collect the bamboo material output from the conveying pipe 32.
[0046] Preferably, the wire splitting spool 1 is arranged horizontally in the axial direction, with a feed inlet 11 at the top away from the first discharge mechanism 3 and a slag discharge outlet 12 at the bottom near the first discharge mechanism 3.
[0047] Preferably, it also includes: a wire splitting drive unit 6, which is located at the other end of the wire splitting drum 1 away from the first discharge mechanism 3 in the axial direction, and drives the wire splitting mechanism 2 to rotate.
[0048] Example 2
[0049] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:
[0050] As a preferred option, such as Figure 5 As shown, the second discharge mechanism 4 further includes a feeding section A43, which is circumferentially distributed on the mounting base 41 and extends radially along the splitting cylinder 1. The side of the feeding section A43 facing the splitting space 102 is set as an arc surface 430 with a narrower width, so that when the second discharge mechanism 4 rotates, a relative positive pressure difference is formed in the splitting cylinder 1.
[0051] Preferably, the baffle A42 and the feeding part A43 are arranged alternately and evenly, and the coarse discharge port 40 is formed between adjacent baffles A42 and feeding parts A43.
[0052] Preferably, the third discharge mechanism 5 further includes a feeding section B52, which is circumferentially distributed on the rotating shaft 20 and extends radially along the splitting cylinder 1. The side of the feeding section B52 facing the first discharge mechanism 3 is provided as a narrower arc surface 430 so that a relative positive pressure difference is formed in the splitting cylinder 1 when the third discharge mechanism 5 rotates.
[0053] In this embodiment, by providing feeding sections A43 and B52 on the second discharge mechanism 4 and the third discharge mechanism 5, and by providing narrowing arc surfaces on the feeding sections A43 and B52, according to the principles of fluid mechanics, when the splitting mechanism 2 rotates, the air pressure in the subdividing space 102 inside the splitting drum 1 is lower than the air pressure in the coarse splitting space 101, thereby forming a relative negative pressure difference between the front and back. The air pressure in the discharge area 104 is lower than the air pressure in the working area 103, thereby forming a relative negative pressure difference between the inside and outside, which promotes the fully graded and split bamboo material to be adsorbed and output. By using a mechanical structure to assist the first discharge mechanism 3 in discharging, the output efficiency is improved and energy saving is increased.
[0054] In a preferred embodiment, four feeding sections A43 and B52 are arranged in a circumferential array.
[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
