Description

Technical Field

[0001] This invention relates to the field of mulberry branch peeling, and more particularly to a mulberry branch peeling device and peeling method. Background Technology

[0002] Mulberry bark fiber is a natural cellulose fiber extracted from the phloem of pruned waste branches. This fiber has a porous cross-section and natural striations on its longitudinal surface. It possesses superior properties compared to cotton and linen, including better moisture absorption (moisture regain 11.21-15.89%), breathability, wrinkle resistance, and antibacterial properties (antibacterial rate 75.7%). Its tensile strength can reach 5.30 cN / dtex, and its luster is close to that of silk. The resulting fiber can be blended with cotton, silk, and linen to develop functional textiles. As a major sericulture country, China recycles 8 million mu (approximately 533,333 hectares) of mulberry branches annually. The development of this fiber realizes the resource utilization of agricultural and forestry waste.

[0003] Mulberry branches consist of an outer bark and an inner core. Only the outer bark fibers can be used to make textiles. Therefore, during production, the mulberry branches need to be peeled to separate the outer bark from the inner core, thus obtaining the processable mulberry bark. However, currently, the peeling process for mulberry branches is mainly done manually, with each person able to process only 8-10 kilograms of mulberry branches per hour, resulting in low production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a mulberry branch peeling device and peeling method, which greatly improves the separation efficiency of the outer bark and inner core of mulberry branches.

[0005] To achieve the above objectives, the present invention provides a mulberry branch peeling device, including a base, on which at least two cooperating bending rollers are rotatably connected, the bending rollers are driven by a driving device, and the roller surface of the bending rollers is provided with protrusions, the protrusions on different bending rollers being staggered along the conveying path of the mulberry branches.

[0006] As a further improvement of the present invention, the bending roller is provided with at least two protrusions, each protrusion being arranged around the rotation axis of the bending roller.

[0007] As a further improvement of the present invention, the protrusion includes an arc-shaped contact surface for kneading mulberry branches, the arc-shaped contact surface is provided with raised oblique textures, and the oblique textures on the arc-shaped contact surface form an angle with the conveying path of the mulberry branches; the oblique textures of different bending rollers have different orientations.

[0008] As a further improvement of the present invention, at least two cooperating traction rollers are rotatably connected to the base, and the traction rollers are arranged in front of the feed end of the bending roller along the conveying path of the mulberry branches; the roller surface of the traction roller is provided with a strip-shaped groove, and the length direction of the strip-shaped groove is parallel to the length of the traction roller.

[0009] As a further improvement of the present invention, at least two cooperating pressure rollers are rotatably connected to the base, and the pressure rollers are arranged in front of the feed end of the traction roller along the conveying path of the mulberry branches.

[0010] As a further improvement of the present invention, a slapping roller is rotatably connected to the base, and a slapping plate is connected to the roller surface of the slapping roller; the slapping roller is arranged behind the discharge end of the bending roller along the conveying path of the mulberry branches.

[0011] As a further improvement of the present invention, at least two cooperating peel-core separating rollers are rotatably connected to the base, and the peel-core separating rollers are arranged behind the patting rollers along the conveying path of the mulberry branches; the roller surface of the peel-core separating rollers is provided with a spiral peeling plate; the spiral peeling plates of two adjacent peel-core separating rollers have opposite directions of rotation.

[0012] To achieve the above objectives, the present invention also provides a method for peeling mulberry branches, wherein the outer bark of the mulberry branch is rubbed alternately from at least two directions along the length of the mulberry branch and bent, thereby causing the outer bark of the mulberry branch to separate from the inner core.

[0013] As a further improvement of the present invention, the mulberry branch is passed between at least two bending rollers, and the outer bark of the mulberry branch is detached from the inner core rod by having the protrusions on different bending rollers alternately rub and bend the mulberry branch from the outside.

[0014] As a further improvement of the present invention, the protrusion of the bending roller rubs the mulberry branches through the arc-shaped contact surface; the radius of the arc-shaped contact surface is not less than 0.5cm.

[0015] As a further improvement of the present invention, when the mulberry branches are rubbed, the bending roller causes the outer bark of the mulberry branches to detach from the inner core rod conveying direction by means of the oblique texture provided on the arc-shaped contact surface.

[0016] As a further improvement of the present invention, before the mulberry branch passes through the bending roller, the mulberry branch passes between at least two traction rollers, and the friction is increased by the transversely arranged strip grooves on the traction rollers, which drive the mulberry branch forward.

[0017] As a further improvement of the present invention, before the mulberry branch passes through the traction roller, the mulberry branch is allowed to pass between at least two pressure rollers, and the pressure rollers flatten the mulberry branch, causing the connection between the outer bark of the mulberry branch and the inner core rod to crack.

[0018] As a further improvement of the present invention, after the mulberry branches pass through the bending roller, the beating plate of the beating roller is used to beat the surface of the mulberry branches, thereby loosening the outer bark and inner core of the mulberry branches.

[0019] As a further improvement of the present invention, after patting the surface of the mulberry branch, the mulberry branch is quickly thrown out, thereby completely separating the outer bark and the inner core of the mulberry branch.

[0020] Beneficial effects Compared with the prior art, the advantages of the mulberry branch peeling device and peeling method of the present invention are as follows: 1. By alternately rubbing and bending mulberry branches from the outside with the protrusions on different bending rollers, the outer bark of the mulberry branches is separated from the inner core rod. This device has a production capacity of 4 tons in 8 hours, which greatly improves production efficiency.

[0021] 2. The raised part of the bending roller rubs the mulberry branch through the arc-shaped contact surface. The bending process is relatively gentle, which minimizes the breakage of the fibers in the outer bark of the mulberry branch and maintains the integrity of the strip mulberry bark fibers, which is beneficial for the subsequent production of textiles.

[0022] 3. The bending roller, through the oblique texture set on the arc-shaped contact surface, causes the outer bark of the mulberry branch to detach from the side that deviates from the conveying direction of the inner core rod, so that the outer bark and the inner core rod are subjected to different forces, thereby improving the separation efficiency.

[0023] 4. The transversely arranged grooves on the traction roller increase the friction between the traction roller and the mulberry branches, preventing slippage and ensuring that the mulberry branches can be conveyed forward quickly.

[0024] 5. After the outer bark of the mulberry branch separates from the inner core rod, they may still stick to each other in some areas. At this time, the surface of the mulberry branch is shaken loose by the beating plate of the beating roller, which makes it easier for the two to be completely separated when they are thrown out later.

[0025] The invention will become clearer from the following description, taken in conjunction with the accompanying drawings, which are used to explain embodiments of the invention. Attached Figure Description

Detailed Implementation

[0028] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0029] Example Specific embodiments of the present invention are as follows: Figures 1 to 6 As shown, a mulberry branch peeling device includes a base 6, on which two cooperating bending rollers 3 are rotatably connected. The bending rollers 3 are linked to a driving device. The roller surface of the bending rollers 3 is provided with protrusions 31. The protrusions 31 on the upper and lower bending rollers 3 are staggered along the conveying path of the mulberry branches 7.

[0030] The bending roller 3 has multiple protrusions 31, and each protrusion 31 is arranged around the rotation axis of the bending roller 3. In this embodiment, each bending roller 3 has 8 protrusions 31.

[0031] The protrusion 31 includes an arc-shaped contact surface 311 for kneading the mulberry branch 7. The arc-shaped contact surface 311 has raised oblique grooves 312, which form an angle with the conveying path of the mulberry branch 7. The oblique grooves 312 of the upper and lower bending rollers 3 have different orientations, which can pull the outer bark of different parts of the mulberry branch 7 in different directions, thereby tearing the bark and making it easier for the bark to detach from the inner core rod. One bending roller 3 has its oblique grooves 312 offset to the left relative to the forward direction of the mulberry branch 7, and the other bending roller 3 has its oblique grooves 312 offset to the right relative to the forward direction of the mulberry branch 7. The radius of the arc-shaped contact surface 311 is not less than 0.5 cm. In this embodiment, the bending roller 3 includes a metal cylinder and multiple steel bars welded to the outside of the cylinder. The arc-shaped contact surface 311 is the cylindrical surface of the steel bars, and the spiral grooves on the cylindrical surface of the steel bars are the oblique grooves 312.

[0032] Two cooperating traction rollers 2 are rotatably connected to the base 6. The traction rollers 2 are positioned in front of the feed end of the bending roller 3 along the conveying path of the mulberry branch 7. The roller surface of the traction roller 2 is provided with six strip-shaped grooves 21. The length direction of the strip-shaped grooves 21 is parallel to the length of the traction roller 2, and each strip-shaped groove 21 is evenly distributed around the axis of the traction roller 2.

[0033] Two mutually cooperating pressure rollers 1 are rotatably connected to the base 6. The pressure rollers 1 are set in front of the feed end of the traction roller 2 along the conveying path of the mulberry branches 7.

[0034] A slapping roller 4 is rotatably connected to the base 6, and multiple slapping plates 41 are connected to the roller surface of the slapping roller 4. The slapping roller 4 is positioned behind the discharge end of the bending roller 3 along the conveying path of the mulberry branches 7. In this embodiment, there are four slapping plates 41 on the slapping roller 4, and the slapping roller 4 is plate-shaped, with each slapping plate 4 perpendicular to the axis of the slapping roller 4.

[0035] Two mutually cooperating peel-and-core separating rollers 5 are rotatably connected to the base 6. The peel-and-core separating rollers 5 are positioned behind the patting roller 4 along the conveying path of the mulberry branches 7. Spiral peeling plates 51 are provided on the roller surface of the peel-and-core separating rollers 5. The spiral peeling plates 51 of two adjacent peel-and-core separating rollers 5 rotate in opposite directions.

[0036] This implementation example Figure 2 As shown, there are two pressure rollers 1, two bending rollers 3, and two core-separating rollers 5 arranged vertically; there are four traction rollers 2, arranged in pairs, with two pairs arranged vertically, and two sets of traction rollers 2 arranged one in front of the other; and one patting roller 4 located above the conveying path of the mulberry branch 7. The axis of each roller is horizontally arranged. The pressure rollers 1, traction rollers 2, bending rollers 3, patting rollers 4, and core-separating rollers 5 are arranged sequentially along the conveying direction of the mulberry branch 7. All five are linked to the drive device through a transmission mechanism. The drive device is a motor 8 mounted on the base 6, and the transmission mechanism is a chain and sprocket mechanism. The upper and lower pressure rollers 1 rotate at the same speed but in opposite directions, the upper and lower traction rollers 2 rotate at the same speed but in opposite directions, the upper and lower bending rollers 3 rotate at the same speed but in opposite directions, the upper and lower core-separating rollers 5 rotate at the same speed but in opposite directions, and the patting roller 4 rotates in the same direction as the bending roller 3 located above the mulberry branch 7. Figure 2 As shown.

[0037] The method for peeling the bark from mulberry branches is as follows: 1) Let the mulberry branch 7 pass through the two pressure rollers 1 along its own length direction. The pressure rollers 1 flatten the mulberry branch 7, causing the connection between the outer bark of the mulberry branch 7 and the inner core rod to begin to crack.

[0038] 2) After passing through the pressure roller 1, the mulberry branch 7 continues to pass between the two sets of front and rear, and the two upper and lower traction rollers 2 of each set. The friction is increased by the horizontally arranged strip grooves 21 on the traction roller 2, which drives the mulberry branch 7 forward.

[0039] 3) After passing through the traction roller 2, the mulberry branch 7 passes between the upper and lower bending rollers 3. The protrusions 31 on the two different bending rollers 3 alternately rub and bend the mulberry branch 7 from the outside, causing the outer skin of the mulberry branch 7 to separate from the inner core rod. Specifically, the protrusions 31 of the bending rollers 3 rub the mulberry branch 7 through the arc-shaped contact surface 311. While rubbing the mulberry branch 7, the bending rollers 3, through the oblique grooves 312 on the arc-shaped contact surface 311, cause the outer skin of the mulberry branch 7 to separate towards the side deviating from the conveying direction of the inner core rod. Because the oblique grooves 312 of one bending roller 3 are offset to the left relative to the forward direction of the mulberry branch 7, and the oblique grooves 312 of the other bending roller 3 are offset to the right relative to the forward direction of the mulberry branch 7, the upper and lower outer skins of the mulberry branch 7 can be offset in different directions relative to the inner core rod, accelerating the tearing of the outer skin and the separation of the outer skin from the inner core rod.

[0040] 4) After the mulberry branch 7 passes through the bending roller 3, the beating plate 41 of the beating roller 4 continuously beats the surface of the mulberry branch 7, loosening the outer bark and inner core rod of the mulberry branch 7 and separating the remaining adhesive parts of the two.

[0041] 5) After the surface of the mulberry branch 7 is tapped, the mulberry branch 7 passes between the upper and lower bark-core separating rollers 5. The bark-core separating rollers 5 quickly throw the mulberry branch 7 forward. Since the spiral peeling plates 51 of the upper and lower bark-core separating rollers 5 rotate in opposite directions, the upper and lower sides of the mulberry branch 7 are subjected to two component forces, one from the left and one from the right, thus completely separating the outer bark and the inner core of the mulberry branch 7. After separation, a processable mulberry branch bark is obtained.

[0042] In addition to the above embodiments, taking the bending roller 3 as an example, depending on the length of the bending roller 3 and the cross-sectional dimensions of the mulberry branch 7, when the length of the bending roller 3 is relatively short, three bending rollers 3 can be set up simultaneously to clamp the mulberry branch 7 from the outside, with the included angle between the axes of adjacent bending rollers 3 being 60°. The remaining pressure roller 1, traction roller 2, beating roller 4, and core-splitting roller 5 can also adopt a similar arrangement.

[0043] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
