Description

Technical Field

[0001] This invention relates to the field of stalk peeling technology, specifically a process for peeling and extracting stalks from jute stalks. Background Technology

[0002] The working principle of a jute peeling machine is to utilize the differences in physical and mechanical properties of different parts of the jute stalk, apply a certain mechanical action, and cause shear stress between the outer epidermis and the woody part of the straw or the bark, resulting in relative displacement, thereby achieving the purpose of separating the jute bark.

[0003] Existing jute peeling machines mainly fall into two categories: the stalk-crushing type and the whole-stalk type. The stalk-crushing type involves feeding the jute stalks through a feeding hopper via a pair of opposing rotating pressure rollers into the meshing area of ​​a pair of peeling rollers. The stalks are crushed and separated from the jute outer layer, which then falls onto a conveyor belt for output. This type has high peeling efficiency, but the crushed stalks are not suitable for secondary use or storage. The whole-stalk type imitates the manual peeling process and mainly includes a transmission mechanism, a stalk-crushing mechanism, a clamping, traction, and separation mechanism, a swinging body, and a rotating body. Its complex mechanism results in lower efficiency. It cannot achieve both the preservation of the jute outer fiber structure and the integrity of the internal stalks. Summary of the Invention

[0004] In order to overcome the defects in the prior art, the purpose of this invention is to provide a process for peeling and extracting jute stalks, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a process for peeling and removing the outer skin of jute stalks, comprising the following steps: A tracked guide rail slide mounted on a support frame is started by PLC control, and a moving platform mounted on it is controlled to drive the peeling blade head to perform a linear reciprocating motion in the horizontal direction.

[0006] S1. First, insert one end of the jute stalk into the cavity formed by several sets of stalk pieces in the stalk breaking tool, and then unfold the several sets of stalk pieces.

[0007] S2. Each unfolded stalk piece corresponds to a trigger rod in the transmission group that moves forward, causing the lever to rotate, which in turn causes the coil spring to pull the unfolded bark head into the outer bark layer of the jute stalk end.

[0008] S3. Continue to insert the jute stalk and connect it with the expanded sheath, thereby causing the outer skin of the jute stalk to expand open;

[0009] S4. Next, insert the other end of the jute stalk into the stalk end clamp and clamp it, and place the stalk on several fixed brackets;

[0010] S5. Restart the stepper motor to drive the moving platform to bring the peeling blade head close to the broken end of the jute stalk, and put its outer skin over the outside of the peeling blade head, so that the straw part inside passes through the inside of the peeling blade head.

[0011] S6. Continue to start the stepper motor to drive the peeling blade head to move towards the stalk end clamp, thereby peeling off the outer skin of the jute stalk and leaving the straw intact;

[0012] S7. Restart the stepper motor to drive the peeling blade away from the stalk end clamp, and repeat steps S1-S6 to continue peeling and removing stalks from other jute stalks.

[0013] As a further improvement to this technical solution, the tracked guide slide is laid out along the length of the support frame. One end of the tracked guide slide is equipped with a stepper motor for driving the track to circulate. Several fixed brackets are fixedly connected side by side on the support frame in front of the tracked guide slide. The peeling blade is annular with a diameter of 40-42mm. The peeling blade is fixedly connected to the moving platform on the tracked guide slide. The peeling blade passes directly above the several fixed brackets. A stalk end clamp is provided on the support frame near the stepper motor.

[0014] As a further improvement to this technical solution, the support frame is equipped with a stalk-breaking knife. The stalk-breaking knife includes several sets of stalk pieces arranged in a circle, several bark-breaking blades arranged in a circle, an expansion sleeve coaxially arranged with the bark-breaking blades, and a transmission assembly for transmitting the deformation force of the stalk pieces to the bark-breaking blades. The jute stalk is inserted into several sets of stalk pieces to expand it, and the transmission assembly drives the bark-breaking blades to unfold synchronously, thereby inserting them into the outer bark layer of the jute stalk. The several sets of stalk pieces and the several bark-breaking blades are coaxially corresponding and equal in number.

[0015] As a further improvement to this technical solution, the transmission assembly includes a coiled spring sheet sleeved with the rear end of the skin-breaking blade, a lever fixedly connected to the rear end of the coiled spring sheet, and a transmission rod hinged to the lever. The skin-expanding sleeve is cylindrical and has several extension rods arranged in a ring at equal intervals along its axial direction on its outside. The transmission rod is embedded in the extension rod and can slide. The sleeve sheet is an arc-shaped piece that narrows in the middle and its rear end is fixedly connected to the bottom of the front end of the extension rod.

[0016] As a further improvement to this technical solution, the outer side of the peeling blade head is provided with several forked blade heads that protrude in a ring at equal intervals, and a movable bracket is suspended on the left side of the peeling blade head.

[0017] As a further improvement to this technical solution, the outer rear end of the sleeve plate is provided with a top block in the shape of a triangular block, the front and rear ends of the extension rod are provided with through grooves, the front and rear ends of the transmission rod both extend out of the through grooves, and the top surface of the front end of the transmission rod is provided with a sliding groove. The top of the top block is engaged with the sliding groove and can slide. The middle part of the lever is rotatably connected to a support rod, and the support rod is fixedly connected to the rear end face of the expansion sleeve.

[0018] As a further improvement to this technical solution, the front end face of the expansion sleeve is provided with several insertion holes in an annular shape. The straight section of the coil spring passes through the insertion holes. A pair of coil rollers are engaged with the rear groove of the shaving head. A pin is inserted into the center hole of the pair of coil rollers and is engaged with the side wall of the groove of the shaving head. The coil rollers are bonded to the front end face of the expansion sleeve. The coil spring is tightly sleeved with the pin. A socket is connected to the lower rear end of the expansion sleeve.

[0019] As a further improvement to this technical solution, the stalk end clamp includes a pair of upper and lower hinged clamps, a hanging rod for closing the pair of clamps, and a fixed seat fixedly connected to the lower clamp. A hanging piece is fixedly connected to the front side of the upper clamp, and a lever is fixedly connected to the front side of the lower clamp. The lever is inverted U-shaped and has tension springs hanging on its two sides. The top of the tension spring is connected to the hanging rod.

[0020] As a further improvement to this technical solution, a number of auxiliary pressure clamps are provided on the support frame and correspondingly behind a number of fixed brackets. The auxiliary pressure clamps include a pressure rod that spans above the tracked guide slide, a fixed sleeve frame that is rotatably connected to the rear end of the pressure rod, and a spring pressure plate that is snapped onto the top of the rear end of the pressure rod. The rear end of the spring pressure plate is vertically bent and bonded to the front side of the fixed sleeve frame. A linkage assembly for pushing the pressure rod upward to avoid the peeling blade head is snapped onto the moving platform on the tracked guide slide. The linkage assembly includes a fixed platform and a rotatable roller embedded in the fixed platform. The central axis of the roller is directly opposite the peeling blade head, and the outer diameter of the roller is larger than the width of the peeling blade head.

[0021] As a further improvement to this technical solution, the peeling process of jute stalks includes the following steps:

[0022] S61. During the process of the peeling blade moving toward the stalk end clamp, the jute stalk is pressed against the fixed bracket by several pressure rods so as not to be broken or bent.

[0023] S62. Before the peeling blade head moves to the fixed bracket, the roller first contacts the pressure rod and lifts it up, so that the peeling blade head can pass through this point to peel the jute stalk.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. This jute stalk peeling and stalk removal process uses a combination of specially designed blades, clamps, guide rails, and supports to simulate the manual peeling process. One end of the jute is fixed by the clamps, and the blades move horizontally with the moving platform in the guide rails, ultimately separating the jute outer skin from the straw. This ensures the integrity of the straw inside the jute without damaging the fiber structure of the jute outer skin.

[0026] 2. The jute stalk peeling and stalk extraction process involves using a stalk-breaking cutter. First, one end of the jute stalk is inserted into the cavity formed by several sets of stalk pieces within the cutter. Then, these sets of stalk pieces are unfolded. Each unfolded stalk piece triggers a corresponding transmission rod in the transmission assembly to move forward, causing a lever to rotate. This, in turn, causes a coil spring to pull the unfolded stalk-breaking cutter head into the outer bark layer of the jute stalk end. As the jute stalk continues to be inserted and engages with the expanding sheath, the outer bark of the jute stalk expands, allowing the broken end of the jute stalk to be smoothly inserted into the peeling cutter head for peeling.

[0027] 3. In this jute stalk peeling and stalk removal process, the peeling blade head moves towards the stalk end clamp via an auxiliary pressure clamp. During this process, several pressure rods press the jute stalk against the fixed bracket, preventing it from being broken or bent. Before the peeling blade head reaches the fixed bracket, the rollers first contact the pressure rods and lift it up, allowing the peeling blade head to pass smoothly through this point and peel the jute stalk.

[0049] Please see Figures 1-11 As shown, this invention provides a process for peeling and removing the outer skin of jute stalks. This includes starting a tracked guide slide 110 mounted on a support frame 100 via PLC control, and controlling a moving platform on the slide to drive the peeling blade 200 in a horizontal linear reciprocating motion to peel off the outer skin of the jute stalks. The tracked guide slide is a mechanical device commonly used in industrial automation and material handling applications. It consists of two parts: a tracked guide and a slide. The slide is typically made of high-quality aluminum alloy or steel with high surface finish, ensuring smooth and precise sliding. When used in conjunction with the tracked guide, it enables long-distance, high-precision linear motion. This is existing technology and will not be described in detail here.

[0050] The principle of peeling jute stalks is to utilize the differences in the physical and mechanical properties of different parts of the jute stalk. By applying a certain mechanical force, shear stress is generated between the outer epidermis and the woody parts or bark of the stalk, causing relative tearing and thus separating the jute bark. Specifically, the steps include:

[0051] S1. First, insert one end of the jute stalk into the cavity formed by several sets of stalk pieces 410 in the stalk breaking tool 400, and then unfold the several sets of stalk pieces 410; that is, determine the outer diameter of the jute stalk through the several sets of stalk pieces 410 so as to match jute stalks of different diameters.

[0052] S2. Each unfolded stalk piece 410 triggers each transmission rod 443 in the transmission assembly 440 to move forward, thereby driving the lever 442 to rotate, which in turn drives the coil spring 441 to pull the bark-breaking blade 420 to unfold and insert into the outer bark layer of the jute stalk end; that is, by using several stalk pieces 410 to simultaneously drive several bark-breaking blades 420 to unfold and match and insert into the outer bark layer of the jute stalk, and then rotating the jute stalk can completely break the outer bark at the end;

[0053] S3. Continue to insert the jute stalk and connect it with the expansion sleeve 430, thereby expanding the outer skin of the jute stalk. The outer diameter of the expansion sleeve 430 is the same as the outer diameter of the peeling blade 200, so that the broken end of the jute stalk can be smoothly inserted into the peeling blade 200 for peeling.

[0054] S4. Next, insert the other end of the jute stalk into the stalk end clamp 300 and clamp it, and place the stalk on several fixed brackets 130; so that the long jute stalk is supported and does not droop.

[0055] S5. Then start the stepper motor 120 to drive the moving platform to move the peeling blade 200 close to the broken end of the jute stalk and put its outer skin over the outside of the peeling blade 200, so that the straw part inside passes through the inside of the peeling blade 200; that is, the peeling blade 200 in linear motion breaks the outer skin of the jute stalk and separates it from the straw, so as to obtain the complete outer skin and straw.

[0056] S6. Continue to start the stepper motor 120 to drive the peeling blade 200 to move towards the stalk end clamp 300, thereby peeling off the outer skin of the jute stalk and leaving the straw intact;

[0057] S7. Restart the stepper motor 120 to drive the peeling blade 200 away from the stalk end clamp 300, and repeat steps S1-S6 to continue peeling and removing stalks from other jute stalks.

[0058] Specifically, the tracked guide slide 110 is laid out along the length of the support frame 100. One end of the tracked guide slide 110 is equipped with a stepper motor 120 for driving the track to circulate. Several fixed brackets 130 are fixedly connected side by side on the support frame 100 in front of the tracked guide slide 110. The peeling head 200 is annular with a diameter of 40-42mm, which can meet the peeling of jute of various outer diameters. The peeling head 200 is fixedly connected to the moving platform on the tracked guide slide 110. The peeling head 200 passes directly above the several fixed brackets 130. A stalk end clamp 300 is provided on the support frame 100 near the stepper motor 120 to clamp one end of the jute stalk, so that the peeling head 200 can be used to peel the outer skin of the entire jute stalk smoothly.

[0059] In addition, the support frame 100 is provided with a stalk breaking cutter 400 so that the broken end of the jute stalk can be easily aligned and fitted onto the peeling cutter head 200; the stalk breaking cutter 400 includes a plurality of stalk pieces 410 arranged in a circle, a plurality of peeling cutter heads 420 arranged in a circle, an expansion sleeve 430 coaxially arranged with the plurality of peeling cutter heads 420, and a transmission assembly 440 for transmitting the deformation force of the stalk pieces 410 to the peeling cutter heads 420;

[0060] Several sets of stalk pieces 410 are inserted into the jute stalk to expand it. The transmission group 440 drives several bark-breaking blades 420 to unfold synchronously and then insert them into the outer bark layer of the jute stalk. The several sets of stalk pieces 410 and the several bark-breaking blades 420 are coaxially corresponding and equal in number; that is, you only need to hold the jute stalk and push it into the bark-breaking blades 400 to get the split end of the jute stalk.

[0061] Specifically, the transmission assembly 440 includes a coiled spring 441 sleeved to the rear end of the shredding blade 420, a lever 442 fixedly connected to the rear end of the coiled spring 441, and a transmission rod 443 hinged to the lever 442. The expansion sleeve 430 is cylindrical and has several extension rods 431 arranged in an annular pattern at equal intervals along its axial direction. The extension rods 431 and the expansion sleeve 430 are integrally formed. The transmission rod 443 is embedded inside the extension rods 431 and can slide, so that the transmission rod 443 is supported and guided. The stalk sleeve 410 is an arc-shaped piece that narrows in the middle and its rear end is fixedly connected to the bottom of the front end of the extension rod 431. Both the stalk sleeve 410 and the shredding blade 420 are made of stainless steel. The structure of the stalk sleeve 410 is elastic and automatically fits jute stalks of different outer diameters.

[0062] Furthermore, the outer side of the peeling blade 200 is provided with several forked blades 201 that protrude in a ring at equal intervals, which are used to peel off the outer skin of the jute stalk to expose the straw part and then remove it smoothly; a movable bracket 210 is suspended on the left side of the peeling blade 200, which is fixedly connected to the movable platform and moves synchronously with the peeling blade 200 to support the jute stalk and prevent it from tilting.

[0063] Specifically, the outer rear end of the sleeve plate 410 is provided with a triangular top block 411, the front and rear ends of the extension rod 431 are provided with through grooves 4311, the front and rear ends of the transmission rod 443 extend out of the through grooves 4311, and the top surface of the extended front end of the transmission rod 443 is provided with a sliding groove 4431. The top of the top block 411 is engaged with the sliding groove 4431 and can slide. The middle part of the lever 442 is rotatably connected to the support rod 4421. The support rod 4421 is fixedly connected to the rear end face of the expansion sleeve 430, so that the lower end of the support rod 4421 has a greater rotation arc than its upper end, thereby allowing the transmission rod 443 to move a small distance to drive the coil spring plate 441 to release a longer length. By changing the rotation point of the support rod 4421 and the lever 442, the angle of the bark-breaking blade 420 is changed so that it can be smoothly inserted into the outer bark layer of the jute stalk.

[0064] When jute stalks are inserted into the cavity formed by several sets of stalk pieces 410, they are squeezed and unfolded, causing the top block 411 to move upward. The top block 411 is squeezed through the inclined surface of the top block 4431, causing the transmission rod 443 to move forward. This causes the upper end of the lever 442 to rotate forward, while its lower end deflects behind the expansion sleeve 430, stretching the coil spring 441. This, in turn, pulls the bark-breaking head 420 to unfold, matching the outer diameter of the jute stalk and inserting it into the outer bark layer.

[0065] It is worth noting that the front end face of the expansion sleeve 430 has several insertion holes 432 in a ring shape, through which the straight section of the coil spring 441 passes. A pair of coil rollers 4411 are engaged in the rear groove of the ripper head 420. A pin is inserted into the center hole of the pair of coil rollers 4411 and is engaged with the side wall of the groove of the ripper head 420. The coil rollers 4411 are bonded to the front end face of the expansion sleeve 430, thereby supporting the ripper head 420 to rotate stably. The coil spring 441 is tightly engaged with the pin, that is, the inner end of the coil spring 441 is bonded to the surface of the pin, so that when the coil spring 441 is stretched, it drives the pin and the ripper head 420 to rotate. When the tension is lost, the coil spring 441 contracts and the ripper head 420 returns to its original position. A socket 450 is connected to the lower rear end of the expansion sleeve 430. The socket 450 is inserted into the support frame 100 for stable use.

[0066] Furthermore, the stalk end clamp 300 includes a pair of vertically hinged clamping plates 310, a hanging rod 320 for closing the pair of clamping plates 310, and a fixing seat 330 fixedly connected to the lower clamping plate 310. One side of the clamping plate 310 is provided with an arc groove for clamping jute stalks. A hanging piece 311 is fixedly connected to the front side of the upper clamping plate 310, and a lever 312 is fixedly connected to the front side of the lower clamping plate 310. The lever 312 is inverted U-shaped and has tension springs 321 hanging on both sides. The top of the tension spring 321 is connected to the hanging rod 320. The lever 312 is made of spring steel. By moving the lever 312 to flip it upwards, the tension spring 321 is retracted, thereby releasing the hanging rod 320 and the hanging piece 311, and thus opening the pair of clamping plates 310.

[0067] In addition, several auxiliary pressure clamps 500 are provided on the support frame 100 and directly behind several fixed brackets 130 to help limit the jute stalks and keep them from bending or breaking during the peeling process. The auxiliary pressure clamps 500 include a pressure rod 510 that spans above the tracked guide slide 110, a fixed sleeve 520 that is rotatably connected to the rear end of the pressure rod 510, and a spring pressure plate 530 that is snapped onto the top of the rear end of the pressure rod 510. The rear end of the spring pressure plate 530 is vertically bent and bonded to the front side of the fixed sleeve 520. The spring pressure plate 530 is made of spring steel and has a thin plate structure. It uses its elasticity to press the jute stalks with different outer diameters onto the pressure rod 510 to keep them straight and flat.

[0068] A linkage assembly 220 is engaged on the moving platform of the tracked guide slide 110 to prevent the pressure rod 510 from colliding with the peeling head 200. The linkage assembly 220 includes a fixed platform 221 and a rotatable roller 222 embedded in the fixed platform 221. The central axis of the roller 222 is directly opposite the peeling head 200, and the outer diameter of the roller 222 is larger than the width of the peeling head 200, so that the roller 222 contacts the pressure rod 510 first and lifts it up, allowing the peeling head 200 to pass smoothly.

[0069] The process of peeling the bark from jute stalks includes the following steps:

[0070] S61. During the process of peeling blade 200 moving toward stalk end clamp 300, several pressure rods 510 press the jute stalk against the fixed bracket 130 so that it is not broken or bent.

[0071] S62. Before the peeling blade 200 moves to the fixed bracket 130, the roller 222 first contacts the pressure rod 510 and lifts it up, so that the peeling blade 200 can pass through this point to peel the jute stalk.

[0072] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention.

A stalk end clamp (300) is provided on the support frame (100) near the stepper motor (120). The process of peeling and extracting stalks from jute stalks includes the following steps: S1. First, insert one end of the jute stalk into the cavity formed by several sets of stalk pieces (410) in the stalk breaking tool (400), and then unfold the several sets of stalk pieces (410). S2. Each unfolded stalk piece (410) triggers each transmission rod (443) in the transmission group (440) to move forward, thereby driving the lever (442) to rotate, which in turn drives the coil spring (441) to pull the bark-breaking head (420) to unfold and insert into the outer bark layer of the jute stalk end; S3. Continue to insert the jute stalk and connect it with the expansion sleeve (430), thereby expanding the outer skin of the jute stalk; S4. Next, insert the other end of the jute stalk into the stalk end clamp (300) and clamp it, and place the stalk on several fixed brackets (130); S5. Start the stepper motor (120) again to drive the moving platform to move the peeling blade (200) close to the broken end of the jute stalk, and put the outer skin of the jute stalk on the outside of the peeling blade (200) so that the straw part inside the jute stalk passes through the inside of the peeling blade (200); S6. Continue to start the stepper motor (120) to drive the peeling blade (200) to move towards the stalk end clamp (300), thereby peeling off the outer skin of the jute stalk and leaving the straw intact; S7. Restart the stepper motor (120) to drive the peeling blade (200) away from the stalk end clamp (300), and repeat steps S1-S6 to continue peeling and removing stalks from other jute stalks.

A hanging piece (311) is fixedly connected to the front side of the upper clamp (310), and a paddle (312) is fixedly connected to the front side of the lower clamp (310). The paddle (312) is inverted U-shaped and tension springs (321) are attached to both sides of the paddle (312). The top of the tension springs (321) is attached to the hanging rod (320).

5. The jute stalk peeling and stalk extraction process according to claim 4, characterized in that: The steps involved in peeling the outer skin off the jute stalks in S6 are as follows: S61. During the process of the peeling blade (200) moving towards the stalk end clamp (300), the jute stalk is pressed against the fixed bracket (130) by several pressure rods (510) so that it is not broken or bent. S62. Before the peeling blade (200) moves to the fixed bracket (130), the roller (222) first contacts the pressure rod (510) and lifts the pressure rod (510), so that the peeling blade (200) can pass through this point smoothly to peel the jute stalk.
