Description

Technical Field

[0001] This utility model belongs to the technical field of peeling equipment accessories, and more specifically it relates to a roller for a mulberry branch peeling equipment. Background Technology

[0002] Mulberry bark, the outer bark of the mulberry tree, is widely used as a raw material for papermaking and textiles. This is because paper made from mulberry bark fibers through processes such as steaming and bleaching has the advantages of fine texture and long shelf life, combining the softness of cotton with the abrasion resistance of linen.

[0003] Mulberry bark peeling is mainly done manually or semi-mechanized. Semi-mechanized peeling involves using roller pressing equipment to press the mulberry branches, thus separating the bark from the branches. Finally, the bark is peeled off manually from the branches.

[0004] However, when placing mulberry branches into the roller press, due to ergonomic limitations and operational inertia, operators typically stand directly in front of the equipment, continuously feeding only the roller in the middle of the peeling machine. The middle section of the roller, subjected to high-frequency, high-load rolling operations over a long period, experiences accelerated wear of its surface texture, aging of the rubber layer, and even deformation of the metal substrate. Meanwhile, the sides of the roller, rarely involved in the work, remain largely in their initial state. This phenomenon leads to long-term wear of the middle section, necessitating the replacement of the entire roller when its performance deteriorates, increasing equipment replacement costs.

[0005] Therefore, there is an urgent need for a roller press for mulberry branch peeling equipment to solve the above problems. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a roller for a mulberry branch peeling device, which has the advantages of convenient adjustment of the position of the roller sleeve and uniform wear of the roller sleeve.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A roller for peeling bark from mulberry branches includes a roller shaft and a roller sleeve fitted on the roller shaft. The outer surface of the roller sleeve is provided with an annular protrusion extending in the circumferential direction.

[0009] The roller sleeve is mounted on the roller shaft via an axial adjustment mechanism.

[0010] The advantages of this scheme are at least as follows: when severe wear is found in the middle of the roller sleeve, the roller sleeve can be shifted to the left or right by a certain distance through the axial adjustment mechanism. This removes the severely worn middle area from the working area, while the lightly worn and in good condition side areas are moved to the high-load working area. This reduces the possibility of premature failure of the entire roller sleeve due to excessive local wear, and achieves uniform wear along the axial length of the entire roller sleeve, thereby effectively extending the service life of the roller sleeve.

[0011] The present invention is further configured such that: a plurality of dovetail protrusions are provided along the axial direction on the outer circumferential surface of the roller pressing shaft, and limiting plates are symmetrically provided at both ends of the roller pressing shaft; the inner wall of the roller pressing sleeve is provided with a plurality of dovetail grooves that match the dovetail protrusions.

[0012] The advantages of this scheme are at least as follows: the dovetail convex strip and dovetail groove provide a stable mechanical connection, which improves the installation stability and axial guidance of the roller sleeve on the roller shaft, and ensures that the roller sleeve will not undergo radial displacement or shaking during axial adjustment, so as to maintain stability during normal use.

[0013] The present invention is further configured such that: the axial adjustment mechanism includes a servo motor and a lead screw; the servo motor is mounted on one of the limiting plates; the two ends of the lead screw are rotatably mounted on the limiting plates at both ends; and one end of the lead screw is connected to the output end of the servo motor for transmission; and the roller sleeve is threadedly connected to the lead screw.

[0014] The advantages of this scheme are at least as follows: When the position of the roller sleeve needs to be adjusted, the servo motor is activated, and the output shaft of the servo motor drives the lead screw to rotate. Since both ends of the lead screw are rotatably mounted on the limit plate, and the roller sleeve is threadedly connected to the lead screw, the rotation of the lead screw will drive the roller sleeve to move along the axial direction of the lead screw. By controlling the rotation direction of the servo motor, the roller sleeve can be moved back and forth on the roller shaft, thereby adjusting the relative position between the roller sleeve and the roller shaft.

[0015] The present invention is further configured such that: the roller shaft is also provided with a self-locking positioning component for fixing the roller sleeve after axial adjustment.

[0016] The advantages of this scheme are at least as follows: the self-locking positioning component can firmly fix the roller sleeve on the roller shaft after the roller sleeve is axially adjusted to the correct position, preventing the roller sleeve from changing position due to vibration or other external forces during operation, thus ensuring the stability and reliability of the roller operation.

[0017] The present invention is further configured such that: the inner wall of the roller sleeve is provided with at least three locking grooves along the axial direction, and the self-locking positioning assembly is disposed inside the roller shaft; the self-locking positioning assembly includes:

[0018] The locking head is axially movable inside the roller shaft, and the locking head can extend into the locking groove to achieve engagement.

[0019] A spring acts on the lock head, causing it to tend to move towards the lock groove;

[0020] The knob is located at the end of the roller shaft;

[0021] A steel wire rope, one end of which is wound and fixed on a knob, and the other end of which passes over a guide wheel located inside the roller shaft and is connected to a lock head.

[0022] The advantages of this scheme are at least as follows: When the position of the roller sleeve needs to be adjusted, by rotating the knob, the wire rope is wound around the knob. As the wire rope is pulled by the knob, it changes direction through the guide wheel inside the roller shaft, pulling the locking head axially backward, compressing the spring, and gradually moving the locking head completely out of the locking groove on the inner wall of the roller sleeve. Then, the displacement of the roller sleeve is adjusted by activating the axial adjustment mechanism. During the movement, since the locking head has retracted, it will not get stuck in the locking groove. When the roller sleeve reaches the target position, the knob is released. The knob may slightly rotate back after the tension of the wire rope weakens, and the locking head pops out instantly under the spring thrust, accurately locking into the new locking groove, completing rigid locking, and ensuring that the roller sleeve is firmly fixed on the roller shaft.

[0023] The present invention is further configured such that: a T-shaped guide groove is provided on the dovetail protrusion of the roller pressing shaft along the axial direction; a T-shaped nut is installed in the T-shaped guide groove; a countersunk hole is provided on the roller pressing sleeve, and a screw matching the T-shaped nut is provided in the countersunk hole.

[0024] The advantages of this scheme are at least as follows: the structure of the T-shaped guide groove, T-shaped nut and screw further enhances the connection strength and stability between the roller sleeve and the roller shaft, while providing additional guidance and positioning during axial adjustment, ensuring the smoothness and accuracy of the roller sleeve movement, and facilitating disassembly.

[0025] The present invention is further configured such that: the T-shaped guide groove, T-shaped nut, countersunk hole and screw are provided axially at intervals on the roller shaft and roller sleeve, and are symmetrically arranged at both ends of the roller shaft and roller sleeve.

[0026] The advantages of this scheme are at least as follows: this symmetrical and spaced arrangement ensures that the entire roller sleeve is firmly fixed in the axial and radial directions, avoiding deformation or damage caused by uneven local stress.

[0027] The present invention is further configured such that the knob is provided with an internal hexagonal groove.

[0028] The advantages of this scheme are at least as follows: the internal hexagonal groove on the knob provides operators with a convenient and labor-saving operating method, making it easy to use an internal hexagonal wrench to rotate the knob.

[0029] The present invention is further configured such that the outer surfaces of the roller shaft and the roller sleeve are both treated with a wear-resistant material coating.

[0030] The advantages of this scheme are at least as follows: after being treated with a wear-resistant material coating, the coating can form a hard protective layer on the surface, reducing wear caused by friction, and can effectively resist the scratching and wear of mulberry branches on the surface of the roller during the rolling process, thereby extending the service life of the roller.

[0031] The present invention is further configured such that the wear-resistant material coating is a hard alloy coating with a thickness ranging from 0.1 mm to 1 mm.

[0032] The advantages of this scheme are at least as follows: when the roller is working, the hard alloy coating can effectively resist the friction and impact of the mulberry branches, reducing the wear of surface materials.

[0033] In summary, this utility model has at least the following advantages:

[0034] 1. By setting up an axial adjustment mechanism, when severe wear is found in the middle position of the roller sleeve, the roller sleeve can be shifted to the left or right by a certain distance through the axial adjustment mechanism. This removes the severely worn middle area from the working area, while the lightly worn and in good condition side areas are moved to the high-load working area. This reduces the premature scrapping of the entire roller sleeve due to excessive local wear, and achieves uniform wear along the axial length of the entire roller sleeve, thereby effectively extending the service life of the roller sleeve.

[0035] 2. By setting a self-locking positioning component, when the position of the roller sleeve needs to be adjusted, the knob is rotated. As the knob rotates, the wire rope is wound around the knob. During the process of the wire rope being pulled by the knob, the wire rope changes direction through the guide wheel inside the roller shaft, pulling the lock head axially backward, compressing the spring, and gradually moving the lock head completely out of the locking groove on the inner wall of the roller sleeve. Then, the displacement of the roller sleeve is adjusted by activating the axial adjustment mechanism. During the movement, since the lock head has retracted, it will not be stuck in the locking groove. When the roller sleeve moves to the target position, the knob is released. The knob may turn slightly back after the tension of the wire rope weakens. The lock head pops out instantly under the action of the spring thrust, accurately locking into the new locking groove, completing rigid locking, and ensuring that the roller sleeve is firmly fixed on the roller shaft.

[0036] 3. By setting up a T-shaped guide groove, T-shaped nut and screw structure, the connection strength and stability between the roller sleeve and the roller shaft are further enhanced. At the same time, it provides additional guidance and positioning during axial adjustment, ensuring the smoothness and accuracy of the roller sleeve movement, and facilitating disassembly.

Detailed Implementation

[0042] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments of this utility model and the features within them can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] Example 1

[0045] A roller for peeling mulberry branches includes a roller shaft 201 and a roller sleeve 202 sleeved on the roller shaft 201. The outer surface of the roller sleeve 202 is provided with an annular protrusion 203 extending circumferentially. The roller sleeve 202 is mounted on the roller shaft 201 through an axial adjustment mechanism 204. When severe wear is found in the middle position of the roller sleeve 202, the roller sleeve 202 can be shifted to the left or right by a certain distance through the axial adjustment mechanism 204. This removes the severely worn middle area from the working area, while the lightly worn and well-maintained side areas are moved to the high-load working area. This reduces the premature scrapping of the entire roller due to excessive local wear, and achieves uniform wear along the axial length of the roller sleeve 202, thereby effectively extending the service life of the roller sleeve 202.

[0046] The outer circumferential surface of the roller pressing shaft 201 is provided with several dovetail protrusions 205 along the axial direction, and the two ends of the roller pressing shaft 201 are symmetrically provided with limiting plates 206; the inner wall of the roller pressing sleeve 202 is provided with several dovetail grooves 207 that match the dovetail protrusions 205. The cooperation between the dovetail protrusions 205 and the dovetail grooves 207 provides a stable mechanical connection, which improves the installation stability and axial guidance of the roller pressing sleeve 202 on the roller pressing shaft 201, and ensures that the roller pressing sleeve 202 will not undergo radial displacement or shaking during axial adjustment, and ensures that it remains stable during normal use.

[0047] In some embodiments, to better realize the forward and backward movement of the roller sleeve 202 on the roller shaft 201, the axial adjustment mechanism 204 includes a servo motor 2041 and a lead screw 2042. The servo motor 2041 is mounted on one of the limiting plates 206, and the two ends of the lead screw 2042 are rotatably mounted on the limiting plates 206 at both ends. One end of the lead screw 2042 is connected to the output end of the servo motor 2041. The roller sleeve 202 is threadedly connected to the lead screw 2042. In other embodiments, the axial adjustment mechanism 204 can also be an electric push rod or a hydraulic push rod mounted at both ends of the roller shaft 201. The output end of the electric push rod or hydraulic push rod is fixedly connected to the end of the roller sleeve 202. During adjustment, by activating the electric push rod or hydraulic push rod, the roller sleeve 202 is pushed and moved along the axial direction of the roller shaft 201 under the action of the dovetail protrusion 205 and the dovetail groove 207.

[0048] In some other embodiments, the axial adjustment mechanism 204 may also include a lead screw, a nut, and a handwheel. The lead screw is mounted on the limiting plate 206, and the nut is connected to the roller sleeve 202. The handwheel is used to manually rotate the lead screw. During operation, rotating the handwheel causes the lead screw to drive the nut to move axially. Since the nut is connected to the roller sleeve 202, the roller sleeve 202 moves axially under the guidance of the dovetail protrusion 205 and the dovetail groove 207, thereby achieving position adjustment.

[0049] To prevent the position of the roller sleeve 202 from changing due to vibration or other external forces during operation, in some embodiments, the roller shaft 201 is also provided with a self-locking assembly 208 for fixing the roller sleeve 202 after axial adjustment. The inner wall of the roller sleeve 202 is provided with at least three locking grooves 209 along the axial direction. The self-locking assembly 208 is located inside the roller shaft 201. The self-locking assembly 208 includes: a locking head 2081, which is axially movable inside the roller shaft 201 and can extend into the locking groove 209 to achieve engagement; a spring 2082, which acts on the locking head 2081 to give it a tendency to move towards the locking groove 209; a knob 2083, which is located at the end of the roller shaft 201; and a wire rope 2085, one end of which is wound and fixed on the knob 2083, and the other end passes around the guide wheel 2086 located inside the roller shaft 201 and is connected to the locking head 2081.

[0050] In a preferred embodiment, the self-locking assembly 208 may further consist of a lock head 2081 and a spring 2082. The lock head 2081 is axially movable inside the roller shaft 201, and the spring 2082 acts on the lock head 2081 to give it a tendency to move towards the locking groove 209. A threaded hole is provided on the roller sleeve 202, and an abutment rod is threaded into the threaded hole. The abutment rod has a cross groove. When releasing the self-locking assembly 208, a Phillips screwdriver is inserted... The rotating abutment rod moves down along the threaded hole in the cross groove, and the other end abuts against the end of the lock head 2081, driving the lock head 2081 to move out of the lock groove 209 and compress the spring 2082 until the lock head 2081 is completely moved out of the lock groove 209. In some embodiments, in order to facilitate the lock head 2081 to spring into the lock groove 209 better, a chamfer or bevel is provided at the end of the lock head 2081, so that the lock head 2081 can enter the lock groove 209 more smoothly.

[0051] It is worth mentioning that the knob 2083 is provided with an internal hexagonal slot 2084, which provides operators with a convenient and labor-saving operating method, making it easy to use an internal hexagonal wrench to rotate the knob 2083.

[0052] In some embodiments, to effectively resist the scratching and wear of mulberry branches on the roller surface during the rolling process, the outer surfaces of the roller shaft 201 and the roller sleeve 202 are treated with a wear-resistant material coating. The wear-resistant material coating is a cemented carbide coating with a thickness ranging from 0.1 mm to 1 mm. The cemented carbide coating can effectively resist the scratching and wear of mulberry branches on the roller surface during the rolling process, reduce the loss of surface material, and thus extend the service life of the roller.

[0053] Example 2

[0054] In some embodiments, to further enhance the connection strength and stability between the roller sleeve 202 and the roller shaft 201, a T-shaped guide groove 210 is provided axially on the dovetail protrusion 205 of the roller shaft 201; a T-shaped nut 211 is installed in the T-shaped guide groove 210; a countersunk hole 212 is provided on the roller sleeve 202, and a screw 213 matching the T-shaped nut 211 is provided in the countersunk hole 212. Through the T-shaped guide groove 210 and the T-shaped nut 211, the radial fixation between the roller sleeve 202 and the roller shaft 201 is further enhanced. With the help of the self-locking positioning component 208, a double fixation is achieved, making the roller sleeve 202 more firmly fixed on the roller shaft 201.

[0055] Among them, T-shaped guide grooves 210, T-shaped nuts 211, countersunk holes 212 and screws 213 are arranged axially at intervals on the roller shaft 201 and roller sleeve 202, and are symmetrically arranged at both ends of the roller shaft 201 and roller sleeve 202. This symmetrical and spaced arrangement ensures that the entire roller sleeve 202 is firmly fixed in the axial and radial directions, avoiding deformation or damage caused by uneven local stress.

[0056] In some other embodiments, inclined grooves may be provided on the roller sleeve 202 and the roller shaft 201. Several inclined grooves are provided axially at intervals on the roller shaft 201 and the roller sleeve 202, and are symmetrically arranged at both ends of the roller shaft 201 and the roller sleeve 202. Wedges are inserted into the inclined grooves, and one end of the wedges is installed in the inclined grooves by snap-fitting, which facilitates disassembly and installation.

[0057] The working process and beneficial effects of this utility model are as follows:

[0058] When severe wear is found in the middle position of the roller sleeve 202, before adjusting the roller sleeve 202, first use a wrench to loosen the screw 213 in the countersunk hole 212 until the head of the screw 213 is completely disengaged from the T-nut 211, thus releasing the locking of the screw 213 with the T-nut 211 and the T-slot. When it is necessary to adjust the position of the roller sleeve 202, rotate the knob 2083. As the knob 2083 rotates, the wire rope 2085 will be wound on the knob 2083. During the process of the wire rope 2085 being pulled by the knob 2083, the wire rope 2085 changes direction through the guide wheel 2086 inside the roller shaft 201, pulling the lock head 2081 axially backward, compressing the spring 2082, and causing the lock head 2081 to gradually move completely out of the lock groove 209 on the inner wall of the roller sleeve 202.

[0059] Subsequently, by starting the servo motor 2041, the output shaft of the servo motor 2041 drives the lead screw 2042 to rotate. Since both ends of the lead screw 2042 are rotatably mounted on the limit plate 206, and the roller sleeve 202 is threadedly connected to the lead screw 2042, the rotation of the lead screw 2042 will drive the roller sleeve 202 to move axially along the lead screw 2042. During the movement, since the locking head 2081 has retracted, it will not be stuck in the locking groove 209. When the roller sleeve 202 moves to the target position, the knob 2083 is released. The knob 2083 may rotate slightly after the tension of the wire rope 2085 is reduced. The locking head 2081 pops out instantly under the pushing force of the spring 2082 and accurately gets into the new locking groove 209, completing the rigid locking and ensuring that the roller sleeve 202 is firmly fixed on the roller shaft 201. By controlling the rotation direction of the servo motor 2041, the roller sleeve 202 can move back and forth on the roller shaft 201, thereby adjusting the relative position between the roller sleeve 202 and the roller shaft 201.

[0060] After adjustment, use a wrench to tighten all the screws 213 in the countersunk holes 212 clockwise. During the tightening process, apply an appropriate torque continuously so that the screws 213 gradually generate sufficient preload. When the preload reaches a suitable level, the inner wall of the roller sleeve 202 can achieve full and tight clamping with the dovetail protrusion 205, the lock head 2081 and the lock groove 209, and the T-nut 211 and the T-shaped guide groove 210. Through the above two fixing methods, axial and radial double fixing is achieved, making the roller sleeve 202 more firmly fixed on the roller shaft 201.

[0061] By shifting the roller sleeve 202 a certain distance to the left or right, the originally severely worn central area is moved away from the working area, while the originally less worn and in good condition side areas are moved to the high-load working area. This reduces the premature scrapping of the entire roller sleeve due to excessive local wear, and achieves uniform wear along the axial length of the entire roller sleeve 202, thereby effectively extending the service life of the roller sleeve 202.

[0062] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0063] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
