Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and in particular to an intelligent polishing device and method for ceramic yarn guide wheels in textile machinery. Background Technology

[0002] In textile machinery, the surface smoothness and contour accuracy of ceramic yarn guide wheels directly affect the smoothness of yarn running and the wear rate. Therefore, regular surface polishing or pre-use polishing is necessary. Polishing ceramic yarn guide wheels removes minor defects and unevenness from their surface, making it smoother, reducing friction and wear during spinning, improving surface quality and precision, thereby extending service life and ensuring smooth spinning.

[0003] Existing yarn guide wheel polishing equipment mostly adopts a single-station fixed operation mode, that is, manual feeding, positioning polishing, and then manual unloading, resulting in low automation and limited production efficiency. In addition, in order to improve efficiency, some equipment adopts a multi-station conveyor structure, but such structures can usually only achieve unidirectional feeding. When returning empty, the equipment is idle, resulting in low overall utilization. Moreover, the movement trajectory of the polishing components is simple, making it difficult to uniformly and fully polish complex contour surfaces such as the arc-shaped yarn guide grooves of the yarn guide wheel. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose an intelligent polishing device and method for ceramic yarn guide wheels in textile machinery.

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

[0006] A smart polishing device for ceramic yarn guide wheels in textile machinery includes a worktable and further includes:

[0007] The feeding mechanism consists of two sets arranged symmetrically on both sides of the workbench, with workpieces to be polished stacked inside.

[0008] A feeding rack is slidably mounted on the workbench for conveying the workpiece at the bottom of the feeding mechanism. The workbench is equipped with a conveying assembly for driving the feeding rack back and forth between the two feeding mechanisms.

[0009] A polishing assembly, mounted on the worktable, is used to polish the workpieces conveyed by the feeder.

[0010] And a receiving seat, which is set on the lower side of the worktable by a support rod, is used to receive the polished workpiece;

[0011] The conveying assembly is linked to a displacement assembly for driving the polishing assembly to move, so that the polishing assembly can fully polish the workpiece being conveyed.

[0012] Preferably, each group of the feeding mechanism includes a plurality of feeding pipes arranged at equal intervals along the width of the workbench, and each feeding pipe is connected to the workbench through a support;

[0013] The bottom of the feed pipe is suspended, and the distance between it and the top wall of the worktable is the height of one workpiece.

[0014] Preferably, the workbench is provided with a sealing assembly for intermittently sealing the bottom opening of the feed pipe. The sealing assembly includes a movable plate connected to the side of the workbench via a first elastic telescopic rod and a sealing plate fixed on the movable plate and corresponding to the feed pipe.

[0015] When the feeding rack conveys the workpiece to the bottom of the feeding pipe under the action of the conveying assembly, the sealing plate seals the bottom of the feeding pipe.

[0016] Preferably, the conveying components are provided in two sets and symmetrically arranged on both sides of the workbench width direction. Each conveying component includes a fixed plate fixed at both ends of the workbench length direction, a first reciprocating screw rotatably connected between the two fixed plates, and a first sleeve threadedly connected to the first reciprocating screw.

[0017] One set of conveying components has a fixed plate equipped with a conveying motor for driving the first reciprocating screw connected to the fixed plate to rotate, and the first reciprocating screw of the other set of conveying components rotates with the first reciprocating screw driven by the conveying motor under the drive of the transmission component.

[0018] Preferably, the feeding frame includes a fixed rod fixed between the first sleeves of the two sets of conveying components and a positioning rod rotatably mounted on the fixed rod and corresponding to the feeding pipes one by one, and a torsion spring is provided between the fixed rod and the positioning rod;

[0019] The workbench is provided with a long slot for the movement of the positioning rod and a wide slot for unloading when the positioning rod rotates relative to the fixed rod.

[0020] Preferably, the fixed rod is provided with a limiting component for restricting the rotation of the positioning rod. The limiting component includes a fixed ring fixed on the fixed rod, a first elastic element sleeved on the fixed rod and connected at one end to the fixed ring, a movable plate connected to the other end of the first elastic element and sliding on the fixed rod, and a limiting rod fixed on the movable plate. The positioning rod is provided with a limiting hole that cooperates with the limiting rod.

[0021] Preferably, auxiliary unloading components are provided on both sides of the workbench. The auxiliary unloading components include a connecting plate connected to the bottom of the workbench via a second elastic telescopic rod and an abutting block fixedly connected to the connecting plate. A force-bearing block is fixedly provided on the movable plate and moves against the abutting block. A force-bearing groove that cooperates with the abutting block is provided on the force-bearing block. A first extrusion inclined surface that cooperates with the inner wall of the force-bearing groove and one end of the abutting block is provided on the force-bearing block.

[0022] The abutment block has a second extrusion slope on the side away from the first extrusion slope.

[0023] Preferably, the auxiliary unloading assembly further includes a U-shaped plate fixed to the bottom of the workbench. A swing plate is rotatably connected to the U-shaped plate via a pin. A torsion spring for driving the swing plate to reset and rotate is provided on the pin. An abutment rod is fixed on the swing plate. A force-bearing rod that cooperates with the abutment rod is provided on the positioning rod, and the force-bearing rod moves against the moving plate.

[0024] Preferably, the polishing assembly includes a horizontal plate fixed between the two feeding mechanisms, a mounting plate slidably connected to the outside of the horizontal plate, and a plurality of electric brush discs disposed on the lower side of the mounting plate. Guide rods are fixed on both sides of the worktable by support plates, and inclined grooves that cooperate with the guide rods are provided on the mounting plate.

[0025] The displacement assembly includes a second reciprocating lead screw rotatably mounted on a fixed plate, a second sleeve threadedly connected to the second reciprocating lead screw, and a connecting plate hinged between the second sleeve and the mounting plate. The second reciprocating lead screw is connected to the first reciprocating lead screw via a transmission component.

[0026] This invention also discloses an intelligent polishing method for ceramic yarn guide wheels in textile machinery. The method involves polishing using the aforementioned intelligent polishing equipment for ceramic yarn guide wheels in textile machinery, and includes the following steps:

[0027] S1: Initial feeding

[0028] The operator places the ceramic guide wheels to be polished into the feed pipes on both sides of the workbench, starts the equipment, and the conveyor motor drives the first reciprocating screw, which moves the feeding frame to the bottom of one side feed pipe. The moving plate on this side is pushed by the force rod, the sealing plate is removed, and the bottom workpiece falls due to gravity and is sleeved on the end of the positioning rod. At this time, the first sleeve is at one end of the first reciprocating screw track groove.

[0029] S2: Conveying

[0030] As the first reciprocating screw continues to rotate, the feeder carries the workpiece to the other side of the worktable. During the movement, the sealing plate resets to prevent the workpiece from falling off the bottom of the feed tube. At this time, the limit rod is inserted into the limit hole, locking the positioning rod to prevent it from swinging under force during polishing.

[0031] S3: Intelligent Polishing

[0032] When the workpiece passes under the polishing assembly, the second sleeve on the second reciprocating screw drives the mounting plate to move through the connecting plate. Due to the cooperation between the inclined groove on the mounting plate and the guide rod, the polishing assembly generates a lateral swing while feeding back and forth, and performs composite trajectory polishing on the surface of the guide wheel and the guide groove.

[0033] S4: Automatic unloading

[0034] After polishing, the feeding rack continues to move to the unloading station. The force block first presses against the first pressing slope of the abutment block on the side, causing the limiting rod to exit the limiting hole. Then the force rod contacts the abutment rod, pushing the positioning rod to flip relative to the fixed rod. The workpiece falls into the receiving seat below through the wide groove.

[0035] S5: Reverse Loop

[0036] The feeding rack continues to move to the other side of the feeding pipe. During this period, the positioning rod is reset under the action of the torsion spring, and then the limit rod is re-inserted into the limit hole. After moving to the other side of the worktable under the feeding pipe, step S1 is repeated to feed the material. As the first reciprocating screw continues to rotate, the feeding rack returns. During the return trip, the feeding, polishing, and unloading processes are also performed to achieve bidirectional continuous production.

[0037] Compared with the prior art, the present invention provides an intelligent polishing device and method for ceramic yarn guide wheels in textile machinery, which has the following beneficial effects:

[0038] 1. In this invention, by symmetrically arranging feeding mechanisms on both sides of the workbench and cooperating with a reciprocating feeding rack, a highly efficient material circulation system is constructed. After the feeding rack completes the loading on one side, it carries the workpiece to move and completes polishing and unloading. Then, without returning empty, it moves directly to the feeding mechanism on the other side for the next loading. The equipment utilizes the characteristics of the reciprocating screw, so that the reciprocating stroke is an effective working stroke, eliminating the idle waiting time of traditional unidirectional feeding equipment, optimizing intermittent single-piece operation into continuous bidirectional assembly line operation, improving the time utilization of the equipment, and increasing production efficiency and production cycle. It is especially suitable for the ceramic guide wheel polishing process that requires large-volume processing.

[0039] 2. In this invention, a linkage locking and unlocking mechanism consisting of a limiting rod, a limiting hole, an elastic element, a force-bearing block, and an abutment block is set up. During the feeding and polishing process, the limiting rod is inserted into the limiting hole of the positioning rod under the action of elastic force, and rigidly locked to prevent the positioning rod from swinging. This effectively prevents the workpiece from swinging or falling off during polishing vibration and stress, ensuring the uniformity of polishing and processing accuracy. When the workpiece reaches the designated unloading position, the purely mechanical inclined plane extrusion triggers the force-bearing block and the movable plate to move axially, causing the limiting rod to automatically exit and unlock. Then, the positioning rod flips under the interference of the force-bearing rod and the abutment rod, accurately throwing the workpiece into the receiving seat. The whole process does not require manual or additional power intervention, and the action is precise and reliable, balancing the contradiction between processing stability and unloading convenience.

[0040] 3. In this invention, the conveying component and the displacement component are mechanically linked. When the first reciprocating screw drives the feeding frame to move longitudinally, the second reciprocating screw is driven to rotate synchronously through the transmission mechanism. The second reciprocating screw drives the mounting plate to move through the second sleeve and the connecting plate. The cooperation constraint between the inclined groove on the mounting plate and the fixed guide rod causes the mounting plate to generate a forced lateral swing while moving longitudinally. This composite motion makes the movement path of the electric brush disc relative to the workpiece no longer a simple straight line, but a composite trajectory containing longitudinal and lateral components. It can more effectively "sweep" non-planar areas such as the V-shaped or arc-shaped guide groove of the guide wheel, avoid polishing dead corners, and significantly improve polishing uniformity and surface smoothness.

[0041] 4. In this invention, by linking the sealing component with the feeding rack, it is ensured that only the bottom of one feeding pipe is open at any given time, preventing the workpiece from accidentally falling off at a non-feeding position and achieving orderly single-piece feeding. At the same time, the auxiliary unloading component is designed with a bidirectional adaptive structure. When the feeding rack carries the unpolished workpiece back through, the second pressing slope of the abutment block allows it to be compressed and avoided by the force block, and the abutment rod can also be pushed and rotated by the force rod, thus preventing the unloading action from being triggered and protecting the unprocessed workpiece. This design enables the equipment to automatically and correctly execute all logic such as feeding, conveying, polishing, unloading, and avoidance in both forward and reverse operating directions, realizing intelligent, fully closed-loop, and intervention-free automated operation.

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0055] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, this embodiment proposes an intelligent polishing device for ceramic yarn guide wheels in textile machinery, including a worktable 1, and further including: a feeding mechanism symmetrically arranged on both sides of the worktable 1, with workpieces to be polished stacked inside; a feeding rack 2 slidably disposed on the worktable 1 for conveying the workpiece at the bottom of the feeding mechanism, and a conveying assembly disposed on the worktable 1 for driving the feeding rack 2 back and forth between the two feeding mechanisms; a polishing assembly disposed on the worktable 1 for polishing the workpieces conveyed by the feeding rack 2; and a receiving seat 14 disposed on the lower side of the worktable 1 via a support rod for receiving the polished workpiece; wherein, the conveying assembly is linked to a displacement assembly for driving the polishing assembly to move, so that the polishing assembly can fully polish the workpiece being conveyed.

[0057] Furthermore, each feeding mechanism includes several feeding pipes 3 arranged at equal intervals along the width of the workbench 1, and each feeding pipe 3 is connected to the workbench 1 through a support.

[0058] The bottom of the feed pipe 3 is suspended, and the distance between it and the top wall of the worktable 1 is the height of one workpiece.

[0059] Specifically, the operator stacks multiple ceramic guide rollers into the feeding mechanisms on both sides of the worktable 1, i.e., inside the feeding pipes 3. The conveying assembly is activated, driving the feeding rack 2 to slide under one side of the feeding pipe 3. The feeding rack 2 picks up the bottom workpiece from under that side of the feeding pipe 3 and then carries the workpiece to the other side of the worktable 1 at a constant speed. As the feeding rack 2 conveys the workpiece under the polishing assembly, the movement of the conveying assembly synchronously drives the displacement assembly to work. The displacement assembly causes the polishing assembly to produce a specific displacement, so that the polishing tool moves above the workpiece along a composite track. The conveyor system performs dynamic and comprehensive polishing on the surface of the moving workpiece. After polishing, the workpiece is moved to the preset unloading point by the feeder 2. Under the action of gravity or a simple guiding mechanism, the workpiece is released from the feeder 2 and falls into the receiving seat 14 below. Then, the conveying component drives the feeder 2 to continue moving until it reaches the feeding pipe 3 of the feeding mechanism on the other side of the worktable 1 to receive the material. Then, the feeder 2 moves in the opposite direction under the action of the conveying component to start the next work cycle. This avoids the invalid time of the empty return of traditional unidirectional conveying equipment and maximizes the space and time utilization of the equipment.

[0060] By constructing a highly efficient closed-loop workflow through a symmetrically arranged feeding mechanism and a reciprocating feeding rack 2, the equipment can automatically complete the entire process from picking up parts, conveying, polishing to unloading. This eliminates the need for frequent manual loading and unloading at individual workstations, greatly reducing auxiliary time and lowering the requirements for physical labor intensity and sustained concentration on operators. It also reduces reliance on skilled polishing workers, which helps reduce labor costs and ensures the stability of the production cycle. It is particularly suitable for polishing large batches of ceramic guide wheels, thereby improving production efficiency.

[0061] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the workbench 1 is further provided with a sealing assembly for intermittently sealing the bottom opening of the feed pipe 3. The sealing assembly includes a movable plate 4 connected to the side of the workbench 1 via a first elastic telescopic rod 401 and a sealing plate 402 fixed on the movable plate 4 and corresponding one-to-one with the feed pipe 3. The first elastic telescopic rod 401 is usually a spring rod or gas spring, which can provide the movable plate 4 with a restoring force in the direction of the feed pipe 3.

[0062] When the feeding rack 2 conveys the workpiece at the bottom of the feeding pipe 3 under the action of the conveying component, the sealing plate 402 seals the bottom of the feeding pipe 3.

[0063] Specifically, when the equipment is not loading materials or the feeding rack 2 has not moved directly under the feeding pipe 3, the first elastic telescopic rod 401 is in its natural state, and all the sealing plates 402 are tightly attached to the lower edge of the bottom opening of the corresponding feeding pipe 3. At this time, the workpieces stacked in the feeding pipe 3 are reliably supported by the bottom sealing plate 402 and cannot fall. When the conveying component drives the feeding rack 2 to move directly under a certain feeding pipe 3 to prepare to receive materials, a specific part of the feeding rack 2 (such as the frame or auxiliary parts) will contact the moving plate 4. As the feeding rack 2 continues to move, it will push the moving plate 4 to overcome the elastic force of the first elastic telescopic rod 401 and move horizontally a short distance along the side of the workbench 1. The moving plate 4 will drive all the sealing plates 402 on it to leave the bottom opening position of the corresponding feeding pipe 3 simultaneously. At this time, the bottom opening of the unsealed feeding pipe 3 opens, and the bottommost single workpiece falls and is stably placed on the receiving position of the feeding rack 2 that has been placed in place. In terms of location; after the feeding is completed, the feeding rack 2 carries the workpiece away from the feeding station. Once the feeding rack 2 is out of contact with the moving plate 4, the elastic force of the first elastic telescopic rod 401 immediately pushes the moving plate 4 back to its initial position, and the sealing plate 402 resets accordingly, resealing the bottom opening of the feeding pipe 3 to prevent the next workpiece from falling at an uninstructed time and to prepare for the next feeding cycle. The entire action is triggered and controlled entirely by the movement of the feeding rack 2 itself, which is a pure mechanical linkage. It eliminates the need for additional sensors, solenoid valves, drivers, and complex control programs, which not only reduces manufacturing costs and maintenance complexity but also significantly improves the long-term operational reliability of the system in industrial environments. Even in the event of an unexpected power outage, emergency stop, or the feeding rack 2 not returning to its accurate position, the sealing plate 402 can firmly hold all workpieces, effectively avoiding potential internal mechanical interference, workpiece accumulation damage, or even personal safety hazards caused by uncontrolled workpiece falling.

[0064] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in a preferred embodiment, based on the above method, the conveying components are further provided in two sets and symmetrically arranged on both sides of the width direction of the workbench 1. Each conveying component includes a fixed plate 5 fixed at both ends of the length direction of the workbench 1, a first reciprocating screw 501 rotatably connected between the two fixed plates 5, and a first sleeve 502 threadedly connected to the first reciprocating screw 501.

[0065] One set of conveying components has a fixed plate 5 equipped with a conveying motor 6 for driving the first reciprocating screw 501 connected to the fixed plate 5 to rotate. The first reciprocating screw 501 of the other set of conveying components rotates with the first reciprocating screw 501 driven by the conveying motor 6 under the drive of the transmission component. The transmission component is such as a coupling, synchronous belt and pulley, gear pair, or sprocket and chain assembly.

[0066] Specifically, when the equipment needs to perform a feeding operation, the conveyor motor 6 starts, driving the first reciprocating screw 501 directly connected to it to start rotating. The rotational power of the conveyor motor 6 is transmitted to the first reciprocating screw 501 on the other side of the worktable 1 through the transmission component, so that it rotates synchronously at the same speed and direction. Since the first reciprocating screws 501 on both sides are reciprocating screws with specific helical grooves, the first sleeve 502 threadedly connected to them will not rotate with the screw, but will move linearly along the axial direction of the first reciprocating screw 501 under the action of the thread pair. When the rotation direction of the screw remains unchanged, the first sleeve 502 will automatically reverse the reciprocating motion after moving to the end of the screw helical groove. By controlling only the start, stop and speed of one conveyor motor 6, the overall reciprocating motion of the feeding rack 2 can be precisely controlled, without the need for a complex multi-axis synchronous control strategy, which reduces the complexity and cost of the electrical control system and improves the reliability of the system.

[0067] like Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, the feeding rack 2 further includes a fixed rod 201 fixed between the first sleeves 502 of the two sets of conveying components and a positioning rod 202 rotatably disposed on the fixed rod 201 and corresponding one-to-one with the feeding pipe 3. A torsion spring is provided between the fixed rod 201 and the positioning rod 202.

[0068] The workbench 1 is provided with a long slot 101 for the movement of the positioning rod 202 and a wide slot 102 for unloading when the positioning rod 202 rotates relative to the fixed rod 201;

[0069] Furthermore, the fixed rod 201 is provided with a limiting component for restricting the rotation of the positioning rod 202. The limiting component includes a fixed ring 7 fixed on the fixed rod 201, a first elastic element 701 sleeved on the fixed rod 201 and connected at one end to the fixed ring 7, a movable plate 702 connected to the other end of the first elastic element 701 and sliding on the fixed rod 201, and a limiting rod 703 fixed on the movable plate 702. The positioning rod 202 is provided with a limiting hole that cooperates with the limiting rod 703.

[0070] Furthermore, auxiliary unloading components are provided on both sides of the workbench 1. The auxiliary unloading components include a connecting plate connected to the bottom of the workbench 1 via a second elastic telescopic rod 8 and an abutting block 801 fixedly connected to the connecting plate. A force-bearing block 9 is fixed on the movable plate 702 and moves against the abutting block 801. A force-bearing groove 901 that cooperates with the abutting block 801 is opened on the force-bearing block 9. A first extrusion inclined surface 8011 that cooperates with the inner wall of the force-bearing groove 901 and one end of the abutting block 801 is opened on both sides.

[0071] A second extrusion slope 8012 is provided on the side of the abutment block 801 away from the first extrusion slope 8011;

[0072] Furthermore, the auxiliary unloading assembly also includes a U-shaped plate 10 fixed to the bottom of the workbench 1. A swing plate 1001 is rotatably connected to the U-shaped plate 10 via a pin. A torsion spring for driving the swing plate 1001 to reset and rotate is provided on the pin. An abutment rod 1002 is fixed on the swing plate 1001. A force-bearing rod 2021 that cooperates with the abutment rod 1002 is provided on the positioning rod 202. The force-bearing rod 2021 moves against the moving plate 4.

[0073] Specifically, when the feeding rack 2 moves to the left side of the worktable 1 below the feeding pipe 3, its force-bearing rod 2021 pushes open the moving plate 4, and the workpiece falls onto the vertical positioning rod 202. The torsion spring keeps the positioning rod 202 in this position, while the limiting rod 703 is inserted into its limiting hole under the spring force, rigidly locking it onto the fixed rod 201 to ensure stability during conveying and polishing. After locking, the feeding rack 2 carries the workpiece and moves smoothly along the long groove 101 under the action of the conveying assembly, moving from the left side of the worktable 1 to the right side. When the workpiece passes through the polishing station, the positioning rod 202 will not swing because it is rigidly locked, thus ensuring the stability of the polishing operation.

[0074] When the feeder 2 carrying the polished workpiece moves to the unloading station on the right side of the worktable 1, the force groove 901 of the force block 9 moves to align with the abutment block 801. Under the guidance and compression of the first extrusion slope 8011, the abutment block 801 enters the force groove 901 and pushes the force block 9 and the movable plate 702 to slide along the fixed rod 201, thereby compressing the first elastic element 701. This action causes the limiting rod 703 to completely exit from the limiting hole of the positioning rod 202, releasing the rotational lock on the positioning rod 202.

[0075] After unlocking, the feeder 2 continues to move a short distance, and the force rod 2021 on the positioning rod 202 then collides with the fixed abutment rod 1002. Since the abutment rod 1002 is restricted by the U-shaped plate 10 and the torsion spring, it cannot move back much. Its reaction force forces the force rod 2021 to drive the entire positioning rod 202 to rotate around its hinge point against the torsion spring force. The workpiece at the end of the positioning rod 202 tilts accordingly. When its center of gravity deviates from the support point, it slides down from the wide groove 102 under the action of gravity and falls into the receiving seat 14 below.

[0076] After the workpiece is unloaded, the feeding rack 2 continues to move, causing the force rod 2021 to separate from the abutment rod 1002. The positioning rod 202 is reset and flipped under the action of the torsion spring. Then the force block 9 is disengaged from the abutment block 801. The first elastic element 701 pushes the movable plate 702 to reset. The limit rod 703 is reinserted into the limit hole of the positioning rod 202, which has been reset to the vertical state by the torsion spring, to complete the locking and prepare for the next material receiving. Then the conveying assembly drives the feeding rack 2 to move to the bottom of the feeding pipe 3 on the right side of the worktable to receive the material.

[0077] As the conveying assembly continues to operate, the feeding rack 2 moves from the right feeding mechanism of the worktable 1 to the left feeding mechanism. When the feeding rack 2 returns from the right side loaded with unpolished workpieces, its force block 9 will first contact the second pressing slope 8012 of the right abutment block 801. This slope design allows the abutment block 801 to be squeezed and compressed to the second elastic telescopic rod 8 to avoid the force block 9, allowing the force block 9 to pass without triggering unlocking. At the same time, the force rod 2021 on the positioning rod 202 will also push the abutment rod 1002 of the swing plate 1001 to rotate and avoid, thereby ensuring that the unpolished workpieces will not be accidentally unloaded during the return trip.

[0078] Through a series of mechanical linkages of "locking-conveying-triggering-collision flipping-gravity unloading-automatic reset", the system achieves automatic and precise unloading at a designated location without the need for any sensors, solenoid valves, or individual actuators. It is highly reliable and suitable for industrial environments. The system enables all logic functions, such as feeding, conveying, polishing, unloading, and obstacle avoidance, to be executed automatically and correctly in both forward and reverse operating directions, achieving intelligent, fully closed-loop, and intervention-free automated operation.

[0079] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the polishing assembly further includes a horizontal plate 11 fixed between the two feeding mechanisms, a mounting plate 111 slidably connected to the outside of the horizontal plate 11, and a plurality of electric brush discs 112 disposed on the lower side of the mounting plate 111. Guide rods 13 are fixed on both sides of the worktable 1 by support plates, and the mounting plate 111 is provided with inclined grooves 131 that cooperate with the guide rods 13.

[0080] The displacement assembly includes a second reciprocating lead screw 12 rotatably mounted on a fixed plate 5, a second sleeve 121 threadedly connected to the second reciprocating lead screw 12, and a connecting plate 122 hinged between the second sleeve 121 and the mounting plate 111. The second reciprocating lead screw 12 is connected to the first reciprocating lead screw 501 via a transmission component. The transmission component may include a coupling, a synchronous belt and pulley, a gear pair, or a sprocket and chain assembly. It should be noted that, since the environment is for polishing and grinding, folded corrugated tubes or dustproof cloth covers may be provided between the mounting components on both sides of the sleeve and the end of the lead screw for dust prevention.

[0081] Specifically, the conveyor motor 6 drives the first reciprocating lead screw 501 to rotate. This rotational motion is synchronously transmitted to the second reciprocating lead screw 12 through the transmission components, causing the two to rotate synchronously according to a fixed transmission ratio. The rotational motion of the second reciprocating lead screw 12 is converted into the linear reciprocating motion of the second sleeve 121 along the axis of the second reciprocating lead screw 12 through the lead screw nut pair. The second sleeve 121 transmits the thrust / pull force to the mounting plate 111 through the connecting plate 122. The actual movement of the mounting plate 111 is strictly constrained by the inclined groove 131 and the fixed guide rod 13; when the connecting plate 122 pushes the mounting plate 111, the mounting plate 111 cannot move freely. The inclined groove 131 on it is forced to slide along the fixed guide rod 13, so that the mounting plate 111 is displaced in the direction driven by the connecting plate 122, and at the same time, it must also generate a forced displacement component in the direction perpendicular to the guide rod 13; the single longitudinal drive is automatically synthesized into a composite motion containing longitudinal and transverse components, so that the electric brush disk 112 can perform "sweeping" polishing on the workpiece surface. Its motion trajectory can more effectively cover the annular surface of the guide wheel and any grooves that may exist, avoiding the striped unevenness caused by single straight-line reciprocating polishing, and significantly improving the uniformity and smoothness of the surface treatment.

[0082] This invention also discloses an intelligent polishing method for ceramic yarn guide wheels in textile machinery. The method involves polishing using the aforementioned intelligent polishing equipment for ceramic yarn guide wheels in textile machinery, and includes the following steps:

[0083] S1: Initial feeding

[0084] The operator places the ceramic guide wheels to be polished into the feed pipes 3 on both sides of the workbench 1, starts the equipment, and the conveyor motor 6 drives the first reciprocating screw 501, which moves the feeding frame 2 to the bottom of one side feed pipe 3. The moving plate 4 on this side is pushed by the force rod 2021, and the sealing plate 402 is moved away. The bottom workpiece falls due to gravity and is sleeved on the end of the positioning rod 202. At this time, the first sleeve 502 is at one end of the track groove of the first reciprocating screw 501.

[0085] S2: Conveying

[0086] As the first reciprocating screw 501 continues to rotate, the feeder 2 carries the workpiece to the other side of the worktable 1. During the movement, the sealing plate 402 resets to prevent the workpiece at the bottom of the feed pipe 3 from falling off. At this time, the limiting rod 703 is inserted into the limiting hole, locking the positioning rod 202 to prevent it from swinging under force during polishing.

[0087] S3: Intelligent Polishing

[0088] When the workpiece passes under the polishing assembly, the second sleeve 121 on the second reciprocating screw 12 drives the mounting plate 111 to move through the connecting plate 122. Since the inclined groove 131 on the mounting plate 111 cooperates with the guide rod 13, the polishing assembly generates lateral swing while feeding back and forth, and performs composite trajectory polishing on the surface of the guide wheel and the guide groove.

[0089] S4: Automatic unloading

[0090] After polishing, the feeding rack 2 continues to move to the unloading station. The force block 9 first presses against the first pressing inclined surface 8011 of the abutment block 801 on the side, causing the limiting rod 703 to exit the limiting hole. Then the force rod 2021 contacts the abutment rod 1002, pushing the positioning rod 202 to flip relative to the fixed rod 201. The workpiece falls into the receiving seat 14 below through the wide groove 102.

[0091] S5: Reverse Loop

[0092] The feeding rack 2 continues to move to the other side of the feeding pipe 3. During this period, the positioning rod 202 is reset under the action of the torsion spring. Then the limiting rod 703 is re-inserted into the limiting hole. After moving to the other side of the feeding pipe 3 of the worktable 1, step S1 is repeated to feed the material. As the first reciprocating screw 501 continues to rotate, the feeding rack 2 returns. During the return trip, the feeding, polishing and unloading processes are also performed to achieve bidirectional continuous production.
