Description

Technical Field

[0001] This invention relates to the field of wood spool polishing technology, specifically a wood spool polishing device. Background Technology

[0002] In existing technologies, wooden wire reels are commonly used in the wire and cable industry for winding, storing, transporting, and laying wires such as electrical wires and cables, optical cables, enameled wires, and steel ropes. Their structure typically consists of two circular plates at both ends and a connecting post in the middle. During the processing of wooden wire reels, the circular plates at both ends are first cut into blanks using a blanking or cutting device. Because the cut circular plates generally have burrs, flash, and other surface defects on their sides, which not only affect the product's appearance but may also scratch the wound wires during use, the sides of the circular plates need to be polished to remove burrs and ensure a smooth surface. Currently, for grinding and polishing operations on disc plates, specialized grinding devices are usually used. These devices generally have a rotary table or a rotating spindle. By fixing the disc plate in the center of rotation of the grinding device, the disc plate is driven to rotate around its axis. At the same time, grinding tools such as grinding heads or sanding belts arranged around the circumference of the disc plate are used to grind and polish the circumference.

[0003] However, the existing sanding devices have significant shortcomings in practical applications. Since sanding requires precise alignment of the disc plate's rotation axis with the sanding device's rotation center to ensure a uniform grinding gap between the sanding tool and the disc plate's side, high precision is required for the disc plate's clamping and positioning. In practice, a dedicated robotic arm or automatic loading / unloading mechanism is typically needed to pick up and precisely transfer the cut disc plates to the sanding device's rotation center. This clamping and positioning process demands high accuracy in both movement and repeatability of the robotic arm, significantly increasing the cost of the robotic arm and its control system, thus raising the overall manufacturing cost of the sanding equipment. Furthermore, the high-precision clamping and positioning also increases the difficulty of equipment debugging and maintenance, hindering the reduction of production investment barriers for small and medium-sized enterprises. Therefore, there is an urgent need for a wood spool sanding and polishing device with a simple structure, low manufacturing cost, and the ability to meet the requirements for sanding and polishing the sides of disc plates. Summary of the Invention

[0004] This invention provides a wood thread polishing device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wood thread spool polishing device includes a base, and a polishing assembly is provided at the end of the base. The polishing assembly includes a three-jaw clamping disc for clamping a disc plate of wood thread spool, and also includes a material storage mechanism and a feeding mechanism.

[0007] The material storage mechanism includes a first bracket fixedly connected to the base on the side away from the grinding component. The first bracket has parallel and synchronously rotating conveyor belts on both sides. A material storage rod is provided between the two conveyor belts. The conveyor belt drives a disc plate sleeved on the material storage rod to move along the material storage rod toward the grinding component. A material storage V-rod is provided at the end of the material storage rod near the grinding component. The V-shaped protrusion of the material storage V-rod faces the ground.

[0008] The feeding mechanism is located between the storage mechanism and the grinding assembly, and includes a height-adjustable feeding trapezoidal frame. After the feeding trapezoidal frame rises, it transfers the disc plate placed on the storage V-bar to the three-jaw clamping plate.

[0009] As a preferred embodiment of the present invention, the first support is provided with parallel crossbeams on both sides, and the two ends of the crossbeams are rotatably connected to a rotating shaft. The two ends of the rotating shaft are provided with drive rollers. The conveyor belt is sleeved on the outside of the drive rollers located at both ends of the same crossbeam. The first support is provided with a reverse rotation drive device for driving the rotating shaft to rotate on the side away from the center of the base.

[0010] As a preferred embodiment of the present invention, a scraper is provided on the outer side of the conveyor belt, and the distance between two scraper strips is greater than the thickness of one disc plate and less than the thickness of two disc plates.

[0011] As a preferred embodiment of the present invention, a flipping seat is provided at one end of the storage V-rod near the grinding assembly. The flipping seat is rotatably connected to a deflection rod. A torsion spring is provided inside the flipping seat to drive the deflection rod to rotate toward the storage V-rod. When the feeding trapezoidal frame pushes the disc plate placed on the storage V-rod to move toward the three-jaw clamping disc, the deflection rod rotates under the gravity of the disc plate to a state flush with the storage V-rod.

[0012] As a preferred embodiment of the present invention, an auxiliary loading assembly for fitting a disc plate onto the storage rod is provided on the side of the storage rod away from the grinding assembly.

[0013] As a preferred embodiment of the present invention, the auxiliary loading assembly includes a second bracket fixedly connected to the end of the base away from the grinding assembly. A flipping shaft is rotatably connected to the end of the second bracket. A flipping plate is fixedly connected to the end of the flipping shaft near the center of the base. A loading rod is fixedly connected to the end of the flipping plate away from the flipping shaft. When the loading rod rotates to a horizontal state, the axis of the loading rod is collinear with the axis of the storage rod. A connecting screw is slidably connected to the end of the loading rod. A screw hole that mates with the connecting screw is provided at the end of the storage rod near the loading rod.

[0014] As a preferred embodiment of the present invention, a feeding pusher plate is slidably connected to the middle of the feeding rod, and a feeding spring is provided between the feeding pusher plate and the flipping plate to drive the feeding pusher plate to move away from the flipping plate.

[0015] As a preferred embodiment of the present invention, the end of the flipping shaft away from the base is fixedly connected to two vertically arranged limiting plates, and the ends of the limiting plates are slidably connected to limiting rods. The second bracket is provided with limiting holes that cooperate with the limiting rods. When the two limiting rods are respectively inserted into the corresponding limiting holes, the loading rod is in a horizontal state toward the storage rod or in a vertical state toward the side away from the ground.

[0016] As a preferred embodiment of the present invention, the feeding mechanism includes a base plate fixedly connected to the base, guide columns are provided on both sides of the base plate, and the middle of each of the two guide columns is slidably connected to the side of the feeding trapezoidal frame near the base plate. A lifting drive device for driving the feeding trapezoidal frame to move up and down is provided in the middle of the base plate. A positioning wheel that cooperates with the disc plate is rotatably connected to the side of the feeding trapezoidal frame near the grinding component. When the feeding trapezoidal frame rises to the top with the lifting drive device, the positioning wheel is at the same height as the rotation center of the three-jaw clamping disc.

[0017] As a preferred embodiment of the present invention, the grinding assembly includes a third bracket fixedly connected to the base, a main shaft rotatably connected to the middle of the third bracket, and the end of the main shaft near the storage mechanism connected to the three-jaw clamping disk. A grinding wheel for grinding the side of the disc plate fixed on the three-jaw clamping disk is provided on the side of the third bracket, and a rotary drive device for driving the grinding wheel and the three-jaw clamping disk to rotate is provided on the third bracket.

[0018] The present invention has the following advantages:

[0019] 1. By setting up the coordinated operation of the storage mechanism, feeding mechanism and grinding components, the disc plate is pre-positioned using the storage straight rod and storage V rod, and then the disc plate is transferred from the storage V rod to the three-jaw clamping plate by the up-and-down moving feeding trapezoidal frame. This realizes the automatic feeding and positioning of the disc plate, avoiding the shortcomings of the existing technology that requires a special robot for high-precision clamping and positioning, thereby significantly reducing the manufacturing cost and debugging and maintenance difficulty of the equipment.

[0020] 2. Due to the use of a storage structure combining a straight storage rod and a V-shaped storage rod, the straight storage rod enables the storage and axial guidance of multiple disc plates, while the V-shaped storage rod uses its V-shaped groove to automatically center and preposition the disc plates conveyed to the end, so that the disc plates are already in the predetermined position before being lifted by the feeding trapezoidal frame, thereby improving the accuracy and consistency of feeding positioning.

[0021] 3. Because scrapers are installed on the outside of the conveyor belt, and the distance between two scrapers is greater than the thickness of one disc plate but less than the thickness of two disc plates, only the disc plate closest to the grinding component is driven forward by the scraper each time. This achieves automatic separation and conveying of disc plates one by one, avoiding jamming or positioning errors caused by multiple disc plates entering the feeding position at the same time, and improving the reliability of feeding.

[0022] 4. Because a deflector rod with a torsion spring is set at the end of the storage V-rod, the deflector rod deflects upward in its natural state, so that the distance between the end of the deflector rod and the three-jaw clamping plate is greater than the thickness of the disc plate. After the disc plate is released, it will automatically fall from the gap to achieve unloading. When feeding, the deflector rod is pressed down by the disc plate to be flush with the storage V-rod, so that the disc plate can smoothly transition to the three-jaw clamping plate. The deflector rod realizes both feeding transition and unloading clearance functions at the same time. The structure is compact and does not require an additional independent unloading mechanism.

[0023] 5. Due to the auxiliary loading component, the loading rod can be switched between horizontal and vertical states by a flipping shaft. When the loading rod is in the vertical state, workers can easily load disc plates in batches from its top. After the loading rod is flipped to the horizontal state, it connects with the storage rod through the connecting screw to form a continuous rod. With the help of the feeding spring-driven feeding push plate, the disc plates are continuously pushed towards the storage rod, making the batch loading operation simple and quick, reducing the labor intensity and time of manual loading one piece at a time.

[0024] 6. Because the feeding trapezoidal frame is rotatably connected to the side of the grinding component, and the positioning wheel is at the same height as the rotation center of the three-jaw clamping plate when the feeding trapezoidal frame rises to the top, the positioning wheel is always in close contact with the side of the disc plate during the grinding process, providing lateral support and positioning for the rotating disc plate, thereby improving the rotational stability and grinding uniformity of the disc plate during the grinding process.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In one embodiment, see Figure 1 and Figure 2 A wood spool polishing device is disclosed for polishing the sides of the circular spool plate 5. The device includes a horizontally placed rectangular base 1, which is a welded steel structure with sufficient strength and rigidity to support the operation of the entire device. A polishing assembly 2 is bolted to the left end of the base 1, and the polishing assembly 2 is used to polish the sides of the circular spool plate 5. A storage mechanism 3 is provided on the right side of the base 1, which stores the circular spool plates 5 to be polished and transports them one by one to the feeding position. A feeding mechanism 4 is provided between the storage mechanism 3 and the polishing assembly 2, which accurately transfers the circular spool plates 5 transported by the storage mechanism 3 onto the three-jaw clamping plate 35 of the polishing assembly 2.

[0041] In one instance of this embodiment, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 12The material storage mechanism 3 includes a first support 6 vertically fixed to the right side of the upper surface of the base 1 by bolts. The first support 6 is an L-shaped frame structure, welded from a column and a bottom beam. Two horizontally extending crossbeams 7 are fixed to the inner side of the column of the first support 6 by bolts. The two crossbeams 7 are parallel to each other and located on the upper and lower sides of the column, respectively. Each crossbeam 7 has a rotating shaft 8 perpendicular to it rotatably connected to its left and right ends via deep groove ball bearings. A cylindrical drive roller 9 is interference-fitted to the front end of the rotating shaft 8. A ring conveyor belt 10 is sleeved around the two drive rollers 9 located at both ends of the same crossbeam 7. The conveyor belt 10 is made of rubber with an anti-slip texture to improve friction with the side of the disc plate 5.

[0042] A reverse rotation drive device 15 is fixedly connected to the side of the first bracket 6 away from the center of the base 1 (i.e., the rear side) via a motor mount. The reverse rotation drive device 15 can optionally be a servo motor, whose output shaft is connected to the rotating shaft 8 at the left end of the two crossbeams 7 via a gear transmission mechanism and a belt transmission mechanism, respectively. This drives the two rotating shafts 8 to rotate at the same speed but in opposite directions, thereby driving the two conveyor belts 10 to move synchronously in opposite directions. When the two conveyor belts 10 move, their opposite inner surfaces move toward the grinding assembly 2 (i.e., to the left), thereby driving the disc plate 5 clamped between the two conveyor belts 10 to move toward the grinding assembly 2 through friction.

[0043] Multiple rectangular scraper blades 11 are fixedly connected to the outer surfaces of the two conveyor belts 10 at equal intervals by bolts. The scraper blades 11 are made of polyurethane, which has a certain degree of elasticity and wear resistance. At any given time, the distance between two oppositely arranged scraper blades 11 is greater than the thickness of one disc plate 5 but less than the thickness of two disc plates 5. This ensures that only one disc plate 5 can be conveyed to the storage V-bar 13 through the gap between the scraper blades 11 at a time, realizing the separation and conveying of disc plates 5 one by one.

[0044] A horizontally extending storage rod 12 is provided at the center between the two conveyor belts 10, with the left end of the storage rod 12 extending to a position close to the feeding mechanism 4. The diameter of the storage rod 12 is slightly smaller than the diameter of the mounting hole at the center of the disc plate 5, so that the disc plate 5 can be freely fitted onto the storage rod 12 and slide along its axial direction.

[0045] The left end of the storage rod 12 is connected to a storage V-rod 13 by welding or integral molding. The storage V-rod 13 is V-shaped when viewed from the front, with the V-shaped protrusion facing the ground and the V-shaped groove facing the sky. The right end of the storage V-rod 13 smoothly transitions to the left end of the storage rod 12, and the left end of the storage V-rod 13 extends above the feed trapezoidal frame 27. When the disc plate 5 is conveyed by the conveyor belt 10 to the left end of the storage rod 12, the disc plate 5 automatically slides into the V-shaped groove of the storage V-rod 13, achieving precise positioning and temporary storage of the disc plate 5.

[0046] A tilting seat 31 is fixedly connected to one end (i.e., the left end) of the storage V-rod 13 near the grinding assembly 2. A deflecting rod 32 is rotatably connected to the tilting seat 31 via a pin. The cross-sectional shape of the deflecting rod 32 is the same as that of the storage V-rod 13. A torsion spring is fitted onto the pin, with one end fixed to the tilting seat 31 and the other end fixed to the deflecting rod 32. In its natural state, the torsion spring drives the deflecting rod 32 to deflect upwards at a certain angle (approximately 15°), making the gap between the end of the deflecting rod 32 and the three-jaw clamping disc 35 greater than the thickness of the disc plate 5. When the three-jaw clamping disc 35 releases the disc plate 5, the disc plate 5 can fall through the gap between the three-jaw clamping disc 35 and the deflecting rod 32, achieving the unloading effect. When the feed trapezoidal frame 27 pushes the disc plate 5 to move along the storage V rod 13 toward the grinding component 2, the disc plate 5 pushes the deflection rod 32 to rotate downward under its own gravity (counterclockwise when viewed from the front). The deflection rod 32 rotates to a state where it coincides with the axis of the storage V rod 13. At this time, the distance between the end of the deflection rod 32 and the three-jaw clamping plate 35 is less than the thickness of the disc plate 5, so that the disc plate 5 is smoothly transferred from the storage V rod 13 to the three-jaw clamping plate 35 under the transition guidance of the deflection rod 32.

[0047] In one instance of this embodiment, please refer to Figure 3 , Figure 6 and Figure 7 An auxiliary loading assembly 14 is provided on the side of the storage rod 12 away from the grinding assembly 2 (i.e., the right side). The auxiliary loading assembly 14 is used to facilitate the operator to load multiple disc plates 5 onto the storage rod 12 in batches at once. The auxiliary loading assembly 14 includes a second bracket 16 that is vertically fixed to the rightmost end of the upper surface of the base 1 by bolts. The top of the second bracket 16 is rotatably connected to a front-to-back oriented flip shaft 19 via a bearing seat. A rectangular flip plate 20 facing the front and back is fixedly connected to the end of the flip shaft 19 near the center of the base 1 (i.e., the front end) by a flat key. A horizontally extending loading rod 21 is fixedly connected to the end of the flip plate 20 away from the flip shaft 19 (i.e., the front end) by threads. The diameter of the loading rod 21 is the same as the diameter of the storage rod 12.

[0048] When the loading rod 21 rotates to a horizontal position, its axis is precisely collinear with the axis of the storage rod 12. An axial sliding hole is provided at the end of the loading rod 21 closest to the storage rod 12, and a connecting screw 23 is slidably connected within the sliding hole. A threaded hole 25 with an internal thread that mates with the connecting screw 23 is provided at the end of the storage rod 12 closest to the loading rod 21. When the loading rod 21 is in a horizontal position, the connecting screw 23 is screwed into the threaded hole 25, thus firmly connecting the loading rod 21 and the storage rod 12 together, forming a continuous long rod. This allows the operator to easily slide the disc plate 5 from the end of the loading rod 21 furthest from the storage rod 12 (i.e., the right end) onto the storage rod 12.

[0049] A circular feed pusher plate 24 is slidably connected to the middle of the storage rod 12. The center of the feed pusher plate 24 has a sliding hole that mates with the storage rod 12. A feed spring 22 is provided between the side of the feed pusher plate 24 facing the tilting plate 20 and the corresponding side of the tilting plate 20. The feed spring 22 is sleeved on the outside of the storage rod 12. When the operator puts multiple disc plates 5 onto the loading rod 21, the feed spring 22 is compressed and stores elastic potential energy, which can continuously push the disc plates 5 towards the grinding assembly 2 (i.e., to the left), so that the leftmost disc plate 5 is always in close contact with the scraper 11 on the conveyor belt 10.

[0050] The end of the flip shaft 19 furthest from the base 1 (i.e., the rear end) extends from the rear side of the second bracket 16 and is fixedly connected to two mutually perpendicular limiting plates 17 by welding. Each limiting plate 17 has a sliding hole at its end, and a cylindrical limiting rod 38 is slidably connected within the sliding hole. The corresponding side of the second bracket 16 has a limiting hole 18 that mates with the limiting rod 38. When the loading rod 21 rotates to a horizontal position, inserting the lower limiting rod 38 into the limiting hole 18 locks the loading rod 21 in a horizontal position; when the loading rod 21 rotates to a vertical position, inserting the lower limiting rod 38 into the limiting hole 18 locks the loading rod 21 in a vertical position, facilitating batch loading operations. Optionally, a return spring is fitted around the limiting rod 38 to prevent it from loosening due to vibration or other reasons after insertion into the limiting hole 18.

[0051] In one instance of this embodiment, please refer to Figures 8-12The feeding mechanism 4 includes a rectangular base plate 26 bolted to the center of the upper surface of the base 1. Two cylindrical guide posts 28 are vertically welded to the front and rear sides of the upper surface of the base plate 26. A linear bearing is fitted in the middle of each guide post 28, and the outer rings of the two linear bearings are fixedly connected to the lower surface of the feeding trapezoidal frame 27. The feeding trapezoidal frame 27 is a trapezoidal frame structure, and its top is a support surface that slopes towards the grinding assembly 2 (i.e., downward to the left), which is used to support the lower edge of the disc plate 5 and push the disc plate 5 to move towards the grinding assembly 2 (i.e., to the left).

[0052] A lifting drive device 29 is bolted to the center of the upper surface of the base plate 26. The lifting drive device 29 can be a cylinder or an electric push rod. A push rod oriented forward and backward is fixedly connected to the top of its piston rod. The front and rear ends of the push rod are respectively fixedly connected to the lower front and rear sides of the feeding trapezoidal frame 27, thus synchronously pushing the feeding trapezoidal frame 27 up and down via the lifting drive device 29. The feeding trapezoidal frame 27 has a right-angled trapezoidal structure. To facilitate the installation of the lifting drive device 29, the lower left part of the feeding trapezoidal frame 27 can be designed as an inwardly recessed structure, providing installation space for the push rod and making the overall structure more compact.

[0053] A cylindrical positioning wheel 30 is rotatably connected to the top of the side (i.e., the left side) of the feeding trapezoidal frame 27 near the grinding assembly 2 via a pin. The positioning wheel 30 is made of rubber and can fit tightly against the side of the disc plate 5. When the feeding trapezoidal frame 27 rises to its highest position with the lifting drive device 29, the rotation center of the positioning wheel 30 is precisely at the same height as the rotation center of the three-jaw gripping disk 35. During the rotation and grinding process of the disc plate 5, the positioning wheel 30 is always pressed tightly against the front and rear sides of the right side of the disc plate 5, providing lateral support for the disc plate 5 and improving the rotational stability of the disc plate 5 during the grinding process.

[0054] In one instance of this embodiment, please refer to Figure 8 and Figure 9 The grinding assembly 2 includes a third bracket 33 vertically fixed to the left end of the upper surface of the base 1 by bolts. A main shaft 34, oriented left-right, is rotatably connected to the middle of the third bracket 33 via two tapered roller bearings. The end of the main shaft 34 near the material storage mechanism 3 (i.e., the right end) extends out of the right side of the third bracket 33 and is fixedly connected to a three-jaw chuck 35 via a flange. The three-jaw chuck 35 is a pneumatic three-jaw chuck used to clamp and fix the center hole of the disc plate 5.

[0055] A grinding wheel 36 is mounted above the third support 33. The grinding wheel 36 can be a flap wheel or a sanding wheel, and its axis is parallel to the axis of the main shaft 34. A rotary drive device 37 is provided on the side of the third support 33 away from the storage mechanism 3 (i.e., the rear side). The rotary drive device 37 includes a main motor and a transmission mechanism. The main motor drives the main shaft 34 and the grinding wheel 36 to rotate through the belt drive mechanism, so that the three-jaw clamping plate 35 and the grinding wheel 36 can rotate synchronously at a predetermined speed. The grinding wheel 36 performs uniform grinding and polishing on the circumferential side of the disc plate 5 that rotates with the three-jaw clamping plate 35.

[0056] The complete working process of the wood spool polishing device provided in this embodiment is described in detail below.

[0057] Step 1: Preparing the Loading Material

[0058] First, rotate the storage rod 12 to separate the screw hole 25 at the end of the storage rod 12 from the connecting screw 23 at the end of the loading rod 21, and place the storage rod 12 directly on the conveyor belt 10 below. Pull out the lower limiting rod 38, flip the loading rod 21 upward to a vertical position, and then insert the limiting rod 38 into the corresponding limiting hole 18 to lock the loading rod 21 in a vertical position.

[0059] The operator inserts multiple disc plates 5 to be polished into the top of the loading rod 21 one by one. Under the action of gravity, the disc plates 5 slide down the loading rod 21 and are stacked on the feeding push plate 24. The feeding spring 22 is compressed during this process.

[0060] After loading is complete, pull out the upper limiting rod 38 and flip the loading rod 21 downwards (counterclockwise). During the flipping process, press down on the disc plate 5 with your hand to prevent the disc plate 5 from coming loose from the loading rod 21. After the loading rod 21 is rotated to a horizontal position, reinsert the limiting rod 38 into the corresponding limiting hole 18 to lock the angle of the loading rod 21.

[0061] Then, place the right end of the storage rod 12 against the left end of the connecting screw 23, and rotate the storage rod 12 so that the connecting screw 23 is screwed into the screw hole 25. After the connecting screw 23 is tightened, the V-shaped protrusion of the storage V-rod 13 is exactly facing the ground. At this time, release the disc plate 5, and the feeding spring 22 pushes the feeding push plate 24 towards the grinding assembly 2 (i.e., to the left), pushing all the disc plates 5 towards the left end of the storage rod 12, so that the leftmost disc plate 5 is in close contact with the scraper 11 on the conveyor belt 10. At this point, the loading preparation work is completed.

[0062] Step 2: Automatic feeding

[0063] The reverse rotation drive device 15 is activated, driving the two conveyor belts 10 to rotate synchronously in opposite directions. The inner surfaces of the two conveyor belts 10 move towards the grinding assembly 2 (i.e., to the left). The scraper 11 on the conveyor belt 10 moves together with the conveyor belt 10. When the scraper 11 passes the leftmost disc plate 5, the end face of the scraper 11 contacts the right side face of the disc plate 5, causing the disc plate 5 to move along the storage rod 12 towards the grinding assembly 2 (i.e., to the left).

[0064] Because the distance between the two opposing scraper blades 11 is less than the thickness of the two disc plates 5, only one disc plate 5 can be moved forward by the scraper blades 11 at a time, realizing the separation and conveying of the disc plates 5 one by one. When the disc plate 5 is conveyed to the left end of the storage rod 12, the disc plate 5 automatically slides into the V-shaped groove of the storage V rod 13 under the action of gravity. At this time, the deflection rod 32 deflects upward under the action of the torsion spring and under the action of gravity, preventing the disc plate 5 from continuing to slide towards the grinding assembly 2, so that the disc plate 5 stops precisely at the predetermined position of the storage V rod 13.

[0065] Step 3: Automatic feeding

[0066] The presence of a disc plate 5 on the storage V rod 13 is detected by a photoelectric sensor, or triggered by the control system according to a preset working rhythm. The control system automatically starts the lifting drive device 29, which drives the feeding trapezoidal frame 27 to move upward along the guide column 28.

[0067] The top support surface of the feeding trapezoidal frame 27 gradually contacts the lower edge of the disc plate 5, pushing the disc plate 5 to move along the storage V-rod 13 toward the grinding assembly 2 (i.e., to the left). As the feeding trapezoidal frame 27 continues to rise, the edge of the center hole of the disc plate 5 contacts the deflection rod 32. Under its own gravity, the disc plate 5 pushes the deflection rod 32 downward to rotate and avoid the disc plate 5. The disc plate 5 continues to move along the deflection rod 32 and gradually fits onto the jaws of the three-jaw clamping disc 35. At this time, the left side of the feeding trapezoidal frame 27 contacts the right side of the disc plate 5.

[0068] As the feed trapezoidal frame 27 continues to move upward, the side of the positioning wheel 30 abuts against the right side of the disc plate 5, and the center hole of the disc plate 5 is completely fitted onto the jaws of the three-jaw clamping disc 35. At this time, the control system or operator controls the three-jaw clamping disc 35 to clamp the disc plate 5, completing the feeding action.

[0069] Step 4: Grinding and Polishing

[0070] After the three-jaw chuck 35 clamps the disc plate 5, the rotary drive device 37 is activated, driving the spindle 34 and the grinding wheel 36 to rotate simultaneously. The spindle 34 drives the disc plate 5 to rotate at a constant speed around its axis through the three-jaw chuck 35, while the grinding wheel 36 rotates at a high speed at a predetermined speed, generating relative grinding motion with the circumferential side of the disc plate 5.

[0071] During the grinding process, the positioning wheel 30 is always in close contact with the right side of the disc plate 5, providing lateral support for the rotating disc plate 5 and ensuring that the disc plate 5 remains stable during rotation. The grinding wheel 36 performs uniform grinding and polishing on the entire circumference of the disc plate 5, removing all burrs, flash and surface defects, so that the side reaches the predetermined smoothness requirements.

[0072] The polishing time can be preset according to the material and surface defects of the disc plate 5. When the preset polishing time is reached, the rotary drive device 37 automatically stops running.

[0073] Step 5: Unloading and Recycling

[0074] After grinding, the lifting drive device 29 drives the feeding trapezoidal frame 27 downward to the initial low position, ready for the next feeding. The control system controls the three-jaw clamping plate 35 to release the jaws, and the ground disc plate 5 falls off the three-jaw clamping plate 35 under the action of gravity. At this time, because the deflection rod 32 is kept in an upward deflection state under the action of the torsion spring, the distance between the end of the deflection rod 32 and the three-jaw clamping plate 35 is greater than the thickness of the disc plate 5. The disc plate 5 falls downward through the gap between the three-jaw clamping plate 35 and the deflection rod 32, and slides down to the lower left along the inclined surface above the feeding trapezoidal frame 27. A collection box can be set on the left side of the base 1 so that the fallen disc plate 5 falls into it.

[0075] At this point, the material storage mechanism 3 has transported the next disc plate 5 to be ground to the material storage V rod 13, and the control system automatically repeats steps three to five to achieve continuous automated production.

[0076] Step Six: Material Replenishment Operation

[0077] Once all the disc plates 5 on the loading rod 21 have been transferred to the storage rod 12, stop the entire device. Rotate the storage rod 12 to separate the connecting screw 23 from the screw hole 25. At this time, the storage rod 12 still has unpolished disc plates 5 passing through it. Because the loading rod 21 passes through the center holes of these disc plates 5, it can remain horizontal between the two conveyor belts 10. Repeat the loading preparation operation in step one to replenish the loading rod 21 with disc plates 5, and reconnect the loading rod 21 and the storage rod 12 through the connecting screw 23 to continue the polishing process of the disc plates 5.

[0078] Step 7: Troubleshooting and Routine Maintenance

[0079] Once all the disc plates 5 on the storage rod 12 have been polished, the equipment will automatically issue an audible and visual alarm to prompt the operator to replenish the material.

[0080] During routine maintenance, it is only necessary to periodically check the tension of the conveyor belt 10, the wear of the grinding wheel 36, and the lubrication of each moving part; no complicated debugging and calibration work is required.

[0081] This invention provides a wood thread spool polishing device. Through the coordinated operation of the storage mechanism 3, the feeding mechanism 4, and the polishing component 2, the storage straight rod 12 and the storage V rod 13 are used to pre-position the disc plate 5. Then, the up-and-down moving feeding trapezoidal frame 27 transfers the disc plate 5 from the storage V rod 13 to the three-jaw clamping plate 35, realizing the automatic feeding and positioning of the disc plate 5. This avoids the shortcomings of the prior art that requires a special robot arm for high-precision clamping and positioning, thereby significantly reducing the manufacturing cost and debugging and maintenance difficulty of the equipment. Meanwhile, the spacing of the scraper strips 11 on the conveyor belt 10 enables the automatic separation and conveying of the disc plates 5 piece by piece, preventing multiple pieces from entering at the same time and causing jamming; the deflection rod 32 at the end of the storage V rod 13 is pressed down to a flush state during feeding to achieve a smooth transition under the action of the torsion spring, and automatically deflects upward to make room for falling during unloading. One rod has the functions of both feeding transition and unloading clearance, making the structure more compact; the positioning wheel 30 provides lateral support to the rotating disc plate 5 during the grinding process, further improving the uniformity and stability of grinding.

[0082] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
