Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to an abrasive replacement structure and replacement method for a grinding equipment. Background Technology

[0002] Grinding equipment is a key processing tool used for surface grinding, polishing, and deburring of workpieces or materials. It is commonly used in metal processing, ceramic products, and composite material finishing. Conventional grinding equipment uses a drive motor to rotate the grinding pot or grinding disc, causing relative motion between the abrasive and the workpiece surface. This achieves the effect of removing excess material and improving surface roughness, playing a vital role in enhancing product surface quality.

[0003] Existing technologies, such as the invention with publication number CN117140301B, disclose a rotary grinding device for irregularly shaped workpieces, including a base, a chuck, a clamping mechanism, a transmission mechanism, a moving mechanism, and two grinding mechanisms. The chuck is mounted on the base, the clamping mechanism clamps the workpiece onto the chuck, and the grinding mechanisms grind the workpiece. This invention's rotary grinding device for irregularly shaped workpieces, by setting up a chuck, clamping mechanism, transmission mechanism, and two grinding mechanisms to cooperate with each other, allows two grinding mechanisms to grind the workpiece simultaneously. The two grinding mechanisms rotate at the same speed but in opposite directions, ensuring that the resultant torque on the workpiece during grinding is zero. This avoids over-grinding of some parts of the workpiece while under-grinding others, improving the grinding effect and making the workpiece more evenly ground.

[0004] The following defects were found in the above-mentioned issues: During the continuous operation of the grinding equipment, it is necessary to replace the worn or failed abrasives periodically. However, since the grinding vessel and drive structure of general grinding equipment are mostly fixed and integrated, it is difficult to remove the abrasive container, which makes it inconvenient to quickly clean and refill the abrasive. This leads to cumbersome abrasive replacement operations, long downtime, and serious impact on continuous production efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as inconvenient abrasive replacement, time-consuming disassembly and assembly, and impact on the continuity of operations.

[0006] To achieve the above objectives, the present invention provides an abrasive replacement structure for a grinding device, comprising: a cabinet, a control panel mounted on one side of the cabinet, a drive motor disposed on the inner wall of the cabinet, the control panel being electrically connected to the drive motor, the upper surface of the drive motor being fixedly connected to the top wall surface of the cabinet, a gear being fixedly connected to the output end of the drive motor, a gear ring being rotatably connected to the upper end of the cabinet corresponding to the position of the gear, the tooth surface of the gear meshing with the tooth surface of the gear ring, a grinding pot being fixedly connected to the upper end of the gear ring via a replacement device, the grinding pot being provided with a replacement device, the replacement device comprising a closing cover and an installation assembly, the closing cover being disposed at the upper end of the grinding pot, the installation assembly being disposed on the side of the grinding pot and the gear ring close to each other, the installation assembly comprising a mounting base, the lower end of the mounting base being fixedly connected to the upper end of the gear ring, and a plurality of abutment claws being uniformly fixedly connected to the upper surface of the mounting base.

[0007] The effect achieved by the above components is as follows: the drive motor is started by controlling the control panel, the drive motor drives the gear to rotate, and the gear drives the grinding kettle to rotate through the gear ring and the closed cover, thereby completing the grinding operation of the material and improving the grinding efficiency.

[0008] Preferably, auxiliary plates are fixedly connected to both ends of the arc surface of the grinding pot. The lower surface of the auxiliary plate near the cabinet abuts against the upper end of the abutting claw. A fastening plate is abutted against the upper surface of the auxiliary plate near the cabinet at the position corresponding to the abutting claw. The same screw is threaded into the surfaces of the fastening plate and the abutting claw. A rotating plate is fixedly connected to the upper end of the screw.

[0009] The effect achieved by the above components is as follows: by rotating the rotating plate, the screw is driven to rotate, so that the fastening plate and the abutment claw clamp and fix the auxiliary plate, thereby realizing a quick and stable connection between the grinding pot and the gear ring, which is convenient for disassembly and replacement.

[0010] Preferably, the inner wall of the grinding vessel is provided with an inner tank, and the surface of the inner tank is evenly provided with a plurality of drainage holes, and a discharge pipe is fixedly connected to one side of the grinding vessel.

[0011] The effect achieved by the above components is to filter the grinding debris and failed abrasive materials generated during grinding through the perforations on the surface of the inner tank and guide them to the discharge pipe for centralized discharge, thereby preventing them from accumulating inside the inner tank, keeping the grinding environment clean and ensuring the grinding effect.

[0012] Preferably, two lifting components are installed on the upper part of the auxiliary plate away from the cabinet. Each lifting component includes a vertical plate, the lower end of which is fixedly connected to the upper surface of the auxiliary plate. Two slide rails are fixedly connected to the sides of the two vertical plates that are close to each other. A lead screw is rotatably connected to the sides of the two slide rails that are close to each other. A servo motor is fixedly connected to the upper end of the vertical plate. The output end of the servo motor is fixedly connected to the upper end of the lead screw. Hanging ears are fixedly connected to the upper end of the inner tank near the lifting components. Lifting plates are rotatably connected to the inner walls of the hanging ears. The sides of the two lifting plates that are far from each other are slidably connected to the sides of the two vertical plates. The inner wall of one side of the lifting plate is slidably connected to the surface of the slide rail. The lead screw is threaded through one end of the lifting plate.

[0013] The aforementioned components achieve the following effects: A servo motor drives a lead screw to rotate, which in turn causes a lifting plate to slide up and down along the vertical plate and slide rail. The lifting plate, via lugs, raises and lowers the inner tank, thus enabling automatic lifting for material discharge or lowering for resetting, facilitating abrasive replacement. Simultaneously, the servo motor controls the inner tank to reciprocate, shaking out any residual debris from the abrasive.

[0014] Preferably, two lifting platforms are fixedly connected to the upper end of the auxiliary plate away from the cabinet. The surface of the lifting platform abuts against the surface of the closed cover. A fastening assembly is provided at the upper end of the lifting platform. The fastening assembly includes two fixing plates. The lower ends of the two fixing plates are fixedly connected to the upper surface of the lifting platform. An abutment plate is slidably connected to one end of the two fixing plates that are close to each other. The lower end of the abutment plate abuts against the upper surface of the closed cover. An eccentric wheel is provided at the upper end of the abutment plate. One side of the eccentric wheel abuts against the upper surface of the abutment plate. Both ends of the eccentric wheel are rotatably connected to the inner walls of the two fixing plates. A handle is fixedly connected to one side of the eccentric wheel. The handle is curved.

[0015] The effect achieved by the above components is as follows: by turning the handle, the eccentric wheel is driven to rotate, and the eccentric wheel pushes the abutment plate to slide down along the fixed plate and presses the closed cover, thereby realizing the quick locking and sealing of the closed cover and the grinding pot, preventing abrasive leakage.

[0016] Preferably, a ventilation and heat dissipation device is installed on one side of the cabinet. The ventilation and heat dissipation device includes several ventilation slots. The ventilation slots are opened on both sides of the cabinet. A fan is fixedly connected to one side of the cabinet corresponding to the position of the ventilation slot. An exhaust pipe is fixedly connected to the input end of the fan. Two air guide plates are provided at the output end of the fan. The upper ends of the two air guide plates are fixedly connected to the top wall of the cabinet. The cross-section of the air guide plates is "C".

[0017] The effects achieved by the above components are as follows: when the fan is running, the airflow enters the fan through the exhaust pipe and is then blown out by the air guide plate, forming air convection inside the cabinet, which carries away the heat generated by the drive motor and prevents the drive motor from overheating; when the corrugated pipe is disconnected from the discharge pipe, the blown airflow can also act on the outside of the grinding kettle to assist in heat dissipation, realizing the reuse of airflow.

[0018] Preferably, the exhaust pipe has a "J" shaped cross-section, the surface of the exhaust pipe is fixedly connected to the upper surface of the cabinet, one end of the exhaust pipe is fixedly connected to a corrugated pipe, one end of the corrugated pipe is fixedly connected to one end of the discharge pipe, a collection box is provided on the upper end of the cabinet corresponding to the exhaust pipe, a groove is opened on the surface of the exhaust pipe corresponding to the position of the collection box, and a filter screen is fixedly connected to the inner wall of the exhaust pipe corresponding to the position of the groove.

[0019] The effect achieved by the above components is as follows: when the discharge pipe and the exhaust pipe are connected through the corrugated pipe, the fan generates suction force through the exhaust pipe, which draws the grinding debris and dust into the exhaust pipe through the discharge pipe and the corrugated pipe. After being filtered by the filter screen, the dust falls into the collection box for centralized collection, thus preventing the dust from being directly discharged into the air.

[0020] Preferably, a replacement assembly is installed at one end of the exhaust pipe and the collection box that are close to each other. The replacement assembly includes a limiting bolt, which is slidably connected to the surface of the exhaust pipe. A limiting plate is fixedly connected to the upper end of the collection box at the position corresponding to the limiting bolt. The lower end of the limiting bolt slides through the middle of the surface of the limiting plate. A spring is sleeved on the arc surface of the limiting bolt, and the two ends of the spring are fixedly connected to one end of the limiting bolt and the surface of the exhaust pipe, respectively.

[0021] The effect achieved by the above components is as follows: by pulling the limit bolt to compress the spring, the limit bolt is disengaged from the limit plate, and the collection box can be removed from the exhaust pipe for cleaning. After being released, the spring drives the limit bolt to automatically reset and lock, thereby realizing the quick disassembly and replacement of the collection box.

[0022] Preferably, a dust-proof sponge is fixedly connected to the inner wall of the exhaust pipe, and the dust-proof sponge is a polyurethane open-cell sponge.

[0023] The effect achieved by the above components is as follows: the airflow entering the exhaust pipe is filtered a second time by the polyurethane open-pore sponge, which effectively adsorbs fine dust particles, thereby further improving the dust removal effect.

[0024] Preferably, a method for changing the abrasive in a grinding device includes the following steps:

[0025] S1. First, start the drive motor via the control panel. The drive motor drives the gear ring to rotate, and the gear ring drives the grinding vessel to rotate via the mounting components and auxiliary plate, mixing and grinding the material and abrasive placed in the inner tank. The fan runs, blowing air through the air guide plate to ventilate and cool the drive motor;

[0026] S2. When grinding is complete, turn the handle to make the eccentric wheel push the abutment plate to release the closed cover, move the closed cover upward, start the servo motor, the servo motor drives the lead screw to reciprocate in both forward and reverse directions, the lead screw drives the lifting plate to slide up and down along the vertical plate and slide rail, the lifting plate drives the inner tank to shake back and forth through the hanging ears, shaking the debris and failed abrasive mixed in the abrasive into the grinding kettle through the leakage hole;

[0027] S3. When cleaning, connect the corrugated pipe to the discharge pipe. The fan generates suction through the exhaust pipe to draw the debris and failed abrasive in the grinding kettle into the exhaust pipe through the discharge pipe and corrugated pipe. After being filtered by the filter screen, it falls into the collection box for centralized collection.

[0028] S4. When it is necessary to change the abrasive, turn the eccentric wheel by turning the handle to raise the abutment plate, loosen the closing cover, and open the closing cover.

[0029] S5. Start the servo motor to drive the lead screw to rotate in the forward direction. The lead screw drives the inner tank to rise through the lifting plate and the hanging lug, lifting the inner tank out of the grinding kettle, pouring out the old abrasive and loading in the new abrasive.

[0030] S6. The servo motor rotates in the reverse direction to lower and reset the inner tank back into the grinding kettle. The closing cover is then put on. The handle is rotated in the reverse direction to push the eccentric wheel to push the abutment plate to press the closing cover tightly, thus completing the seal.

[0031] S7. When cleaning the collection box regularly, pull the limit bolt to compress the spring and disengage it from the limit plate. Remove the collection box and clean the dust inside. After cleaning, push the collection box back and loosen the limit bolt. The spring will drive the limit bolt to automatically insert into the limit plate to complete the locking.

[0032] S8. Turn off the drive motor, servo motor and fan via the control panel to end the grinding operation.

[0033] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0034] In this invention, by setting up a replacement device, the abutment claw on the mounting base and the fastening plate are clamped and fixed by a screw and a rotating plate, realizing the quick assembly and disassembly of the grinding vessel and the gear ring. The servo motor of the lifting assembly drives the lead screw to rotate, and the lead screw drives the lifting plate to slide along the slide rail and the vertical plate. The lifting plate drives the inner tank to automatically lift and remove or reset through the hanging lug. At the same time, the servo motor reciprocates forward and reverse, causing the inner tank to shake, shaking the debris through the leakage hole into the grinding vessel and then discharging it through the discharge pipe. The fastening assembly, by turning the eccentric wheel with the handle, pushes the abutment plate to slide along the fixed plate to press or loosen the closing cover, realizing quick locking and sealing. The above structures work together to complete the abrasive cleaning and replacement without disassembling the entire equipment, greatly shortening downtime and effectively solving the problems of cumbersome abrasive replacement operation, time-consuming disassembly and assembly, and impact on continuous production efficiency of traditional grinding equipment. This significantly improves the convenience of equipment maintenance and the continuity of operation.

[0035] In this invention, a ventilation and heat dissipation device is installed. When the fan is running, it generates suction through the exhaust pipe, which is connected to the discharge pipe via a corrugated pipe. This suction pipe draws debris and dust from the grinding vessel into the exhaust pipe, where it is filtered and collected in a collection box. Fine dust is then adsorbed a second time by a polyurethane perforated sponge, achieving efficient dust removal. To replace components, the collection box can be quickly removed for cleaning by pulling the limit bolt and compressing the spring to disengage it from the limit plate. After release, the spring automatically resets and locks the limit bolt, facilitating maintenance. When the corrugated pipe is disconnected from the discharge pipe, the airflow from the fan is blown out through a C-shaped guide plate, creating air convection inside the cabinet. This provides ventilation and heat dissipation for the drive motor and the outside of the grinding vessel, allowing for airflow reuse. This structure works synergistically in both dust removal and heat dissipation, preventing dust from being directly released into the air and polluting the environment, while also effectively preventing the drive motor from overheating during prolonged operation. This solves the problem of existing equipment lacking integrated dust removal and heat dissipation functions, which leads to poor working environments and reduced equipment lifespan.

[0047] like Figures 1 to 2 As shown, the present invention provides an abrasive replacement structure for a grinding equipment, comprising: a cabinet 1 and a control panel 2. The control panel 2 is installed on one side of the cabinet 1. A drive motor 3 is provided on the inner wall of the cabinet 1. The control panel 2 is electrically connected to the drive motor 3. The upper surface of the drive motor 3 is fixedly connected to the top wall surface of the cabinet 1. A gear 4 is fixedly connected to the output end of the drive motor 3. A gear ring 5 is rotatably connected to the upper end of the cabinet 1 corresponding to the position of the gear 4. The tooth surface of the gear 4 meshes with the tooth surface of the gear ring 5. A grinding pot 6 is fixedly connected to the upper end of the gear ring 5 by means of a replacement device 7. The grinding pot 6 is provided with the replacement device 7. A ventilation and heat dissipation device 8 is installed on one side of the cabinet 1.

[0048] The following section will describe in detail the specific settings and functions of the replacement device 7 and the ventilation and heat dissipation device 8.

[0049] like Figures 3 to 5As shown, the replacement device 7 includes a closing cover 71 and an installation component 72. The closing cover 71 is located at the upper end of the grinding vessel 6. The installation component 72 is installed on the side of the grinding vessel 6 and the gear ring 5 close to each other. The installation component 72 includes a mounting base 721. The lower end of the mounting base 721 is fixedly connected to the upper end of the gear ring 5. Several abutment claws 722 are evenly fixedly connected to the upper surface of the mounting base 721. The drive motor 3 is started by controlling the control panel 2. The drive motor 3 drives the gear 4 to rotate. The gear 4 drives the grinding vessel 6 to rotate through the gear ring 5 and the closing cover 71, thereby completing the grinding operation of the material and improving the grinding efficiency. Auxiliary plates 73 are fixedly connected to both ends of the arc surface of the grinding pot 6. The lower surface of the auxiliary plate 73 near the cabinet 1 abuts against the upper end of the abutting claw 722. A fastening plate 725 is abutted against the upper surface of the auxiliary plate 73 near the cabinet 1 at the position corresponding to the abutting claw 722. The same screw 723 is threaded into the surfaces of the fastening plate 725 and the abutting claw 722. A rotating plate 724 is fixedly connected to the upper end of the screw 723. By rotating the rotating plate 724, the screw 723 is rotated, so that the fastening plate 725 and the abutting claw 722 clamp and fix the auxiliary plate 73, thereby realizing a quick and stable connection between the grinding pot 6 and the toothed ring 5, which is convenient for disassembly and replacement. The inner wall of the grinding vessel 6 is provided with an inner tank 74. The surface of the inner tank 74 is evenly provided with several drainage holes 78. A discharge pipe 79 is fixedly connected to one side of the grinding vessel 6. The grinding debris and failed abrasive materials generated are filtered through the drainage holes 78 on the surface of the inner tank 74 and guided to the discharge pipe 79 for centralized discharge, thereby preventing them from accumulating inside the inner tank 74, keeping the grinding environment clean and ensuring the grinding effect. Two lifting components 76 are installed on the upper part of the auxiliary plate 73 away from the cabinet 1. The lifting component 76 includes a vertical plate 761. The lower end of the vertical plate 761 is fixedly connected to the upper surface of the auxiliary plate 73. Two slide rails 762 are fixedly connected to the side of the two vertical plates 761 that are close to each other. A lead screw 763 is rotatably connected to the side of the two slide rails 762 that are close to each other. A servo motor 764 is fixedly connected to the upper end of the vertical plate 761. The output end of the servo motor 764 is fixedly connected to the upper end of the lead screw 763. Hanging ears 765 are fixedly connected to the upper part of the inner tank 74 near the lifting component 76. Lifting plates 766 are rotatably connected to the inner wall of 65. The sides of the two lifting plates 766 that are far apart from each other are slidably connected to one side of the two vertical plates 761. The inner wall of one side of the lifting plate 766 is slidably connected to the surface of the slide rail 762. A lead screw 763 is threaded through one end of the lifting plate 766. The lead screw 763 is driven to rotate by a servo motor 764. The lead screw 763 drives the lifting plate 766 to slide up and down along the vertical plate 761 and the slide rail 762. The lifting plate 766 drives the inner tank 74 to rise and fall through the lug 765, thereby realizing the automatic lifting and unloading or lowering and resetting of the inner tank 74 for easy replacement of abrasive. At the same time, the servo motor 764 controls the inner tank 74 to reciprocate and shake out residual debris in the abrasive.Two lifting platforms 75 are fixedly connected to the upper end of the auxiliary plate 73, which is away from the cabinet 1. The surface of the lifting platform 75 abuts against the surface of the closing cover 71. A fastening assembly 77 is provided at the upper end of the lifting platform 75. The fastening assembly 77 includes two fixing plates 771. The lower ends of the two fixing plates 771 are fixedly connected to the upper surface of the lifting platform 75. An abutment plate 772 is slidably connected to the ends of the two fixing plates 771 that are close to each other. The lower end of the abutment plate 772 abuts against the upper surface of the closing cover 71. The upper end of the abutment plate 772 is provided with... An eccentric wheel 773 is provided, with one side of the eccentric wheel 773 abutting against the upper surface of the abutment plate 772. Both ends of the eccentric wheel 773 are rotatably connected to the inner walls of the two fixed plates 771. A handle 774 is fixedly connected to one side of the eccentric wheel 773. The handle 774 is curved. By rotating the handle 774, the eccentric wheel 773 is driven to rotate. The eccentric wheel 773 pushes the abutment plate 772 to slide downward along the fixed plate 771 and presses the closing cover 71, thereby achieving a quick locking and sealing between the closing cover 71 and the grinding vessel 6 to prevent abrasive leakage.

[0050] like Figures 6 to 8As shown, the ventilation and heat dissipation device 8 includes several ventilation slots 89, which are opened on both sides of the cabinet 1. A fan 81 is fixedly connected to one side of the cabinet 1 at the position corresponding to the ventilation slot 89. An exhaust pipe 83 is fixedly connected to the input end of the fan 81. Two air guide plates 82 are provided at the output end of the fan 81. The upper ends of the two air guide plates 82 are fixedly connected to the top wall of the cabinet 1. The cross-section of the air guide plates 82 is "C" shaped. When the fan 81 is running, the airflow enters the fan 81 through the exhaust pipe 83 and is then blown out by the air guide plates 82, forming air convection inside the cabinet 1, which carries away the heat generated by the drive motor 3 and prevents the drive motor 3 from overheating. When the corrugated pipe 84 is disconnected from the discharge pipe 79, the blown airflow can also act on the outside of the grinding pot 6 to assist in heat dissipation, realizing the reuse of airflow. The exhaust duct 83 has a "J" shaped cross-section. The surface of the exhaust duct 83 is fixedly connected to the upper surface of the cabinet 1. One end of the exhaust duct 83 is fixedly connected to a corrugated pipe 84. One end of the corrugated pipe 84 is fixedly connected to one end of the discharge pipe 79. A collection box 85 is provided on the upper end of the cabinet 1 corresponding to the exhaust duct 83. A groove is opened on the surface of the exhaust duct 83 corresponding to the position of the collection box 85. A filter screen 86 is fixedly connected to the inner wall of the exhaust duct 83 corresponding to the position of the groove. When the discharge pipe 79 is connected to the exhaust duct 83 through the corrugated pipe 84, the fan 81 generates suction force through the exhaust duct 83, which draws the grinding debris and dust into the exhaust duct 83 through the discharge pipe 79 and the corrugated pipe 84. After being filtered by the filter screen 86, the dust falls into the collection box 85 for centralized collection, preventing the dust from being directly discharged into the air. A replacement component 88 is installed at one end of the exhaust pipe 83 and the collection box 85 that are close to each other. The replacement component 88 includes a limit bolt 881, which is slidably connected to the surface of the exhaust pipe 83. A limit plate 882 is fixedly connected to the upper end of the collection box 85 at the position corresponding to the limit bolt 881. The lower end of the limit bolt 881 slides through the middle of the surface of the limit plate 882. A spring 883 is sleeved on the arc surface of the limit bolt 881. The two ends of the spring 883 are fixedly connected to one end of the limit bolt 881 and the surface of the exhaust pipe 83, respectively. By pulling the limit bolt 881 to compress the spring 883, the limit bolt 881 is disengaged from the limit plate 882, and the collection box 85 can be removed from the exhaust pipe 83 for cleaning. After being released, the spring 883 drives the limit bolt 881 to automatically reset and lock, thereby realizing the quick disassembly and replacement of the collection box 85. A dust-proof sponge 87 is fixedly connected to the inner wall of the exhaust duct 83. The dust-proof sponge 87 is a polyurethane open-cell sponge. The airflow entering the exhaust duct 83 is filtered a second time by the polyurethane open-cell sponge 87, which effectively adsorbs fine dust particles, thereby further improving the dust removal effect.

[0051] The working principle of the abrasive replacement structure of the grinding equipment provided by this invention is as follows: When using this device for material grinding, preliminary preparation and routine grinding operations are first performed. The operator sets the operating parameters through the control panel 2. The control panel 2 is electrically connected to the drive motor 3. After starting the drive motor 3, the output end of the drive motor 3 drives the gear 4 to rotate. The tooth surface of the gear 4 meshes with the tooth surface of the gear ring 5, thereby transmitting power to the gear ring 5. The upper end of the gear ring 5 is fixedly connected to the grinding vessel 6 by means of a closing cover 71. The grinding vessel 6 rotates smoothly under the drive of the gear ring 5, and the material and abrasive placed in the inner tank 74 of the grinding vessel 6 tumble and mix accordingly, achieving efficient grinding. During this process, the cabinet 1 provides stable support for the overall structure. The auxiliary plate 73 is fixed at both ends of the arc surface of the grinding pot 6. The lower surface of the auxiliary plate 73 near the cabinet 1 abuts against the upper ends of several abutting claws 722 on the mounting base 721 in the mounting assembly 72. At the same time, the fastening plate 725 abuts against the position of the abutting claws 722 on the upper surface of the auxiliary plate 73. By rotating the rotating plate 724, the screw 723 is rotated, so that the fastening plate 725 and the abutting claws 722 clamp and fix the auxiliary plate 73, thereby realizing a quick and stable connection between the grinding pot 6 and the toothed ring 5. This ensures the reliability of rotary grinding and facilitates subsequent disassembly and replacement. Several drainage holes 78 are evenly opened on the surface of the inner tank 74. During the grinding process, the generated debris and failed abrasive are filtered into the interior of the grinding pot 6, preventing debris from accumulating in the inner tank 74, keeping the grinding environment clean, and ensuring the continuous stability of grinding quality.

[0052] The replacement device 7 is the core improvement of this invention. It integrates a closing cover 71, a mounting component 72, a lifting component 76, and a fastening component 77, and is specifically optimized for abrasive replacement needs. After a period of regular grinding, it is necessary to clean up the debris and replace it with new abrasive. At this time, the operator first performs the debris shaking step: the servo motor 764 is started. The servo motor 764 is fixed to the upper end of the vertical plate 761, and its output end is fixedly connected to the upper end of the lead screw 763. The lead screw 763 rotates, driving the lifting plate 766 to slide up and down along the vertical plate 761 and the slide rail 762. The lifting plate 766 is connected to the upper end of the inner tank 74 through the hanging lug 765, thereby driving the inner tank 74 to shake back and forth, accelerating the shaking of debris and expired abrasive mixed in with the abrasive into the inner cavity of the grinding vessel 6 through the leakage hole 78, preparing for subsequent abrasive replacement. The abrasive replacement operation is then performed: First, rotate handle 774, which is bent and fixedly connected to eccentric wheel 773. Both ends of eccentric wheel 773 are rotatably connected to the inner wall of fixed plate 771. Rotating handle 774 causes eccentric wheel 773 to deflect, releasing the clamping force on abutment plate 772. Abutment plate 772 rises along fixed plate 771, releasing closing cover 71, allowing the operator to open closing cover 71. Then, the servo motor 764 is restarted, driving lead screw 763 to rotate forward. Lead screw 763 is connected to lifting plate 766 and hanging... The ear 765 drives the inner can 74 to rise smoothly along the slide rail 762. The lifting platform 75 provides support and guidance on the upper end of the auxiliary plate 73, allowing the inner can 74 to be completely lifted and removed from the grinding pot 6. The old abrasive is poured out and new abrasive is loaded. After loading, the servo motor 764 rotates in the reverse direction, and the inner can 74 descends and resets back into the grinding pot 6. The closing cover 71 is then closed. The handle 774 rotates in the reverse direction, causing the eccentric wheel 773 to push the abutment plate 772 downward and press the closing cover 71, achieving a quick and tight seal to prevent abrasive leakage during subsequent grinding. The entire replacement process, through the precise control of the servo motor 764 and the quick pressing structure of the eccentric wheel 773, significantly shortens downtime and improves work efficiency. At the same time, the reciprocating swaying function of the lifting component 76 can also be used to thoroughly empty residual debris before replacement, ensuring that the old and new abrasives are not mixed and guaranteeing consistent grinding quality.

[0053] The ventilation and heat dissipation device 8 serves the dual functions of dust collection and heat dissipation. It includes a fan 81, an exhaust duct 83, an air guide plate 82, a corrugated pipe 84, a collection box 85, and a replacement component 88. During the debris cleaning stage after grinding, the operator fixes one end of the corrugated pipe 84 to the discharge pipe 79 and the other end to the exhaust duct 83. The exhaust duct 83 has a J-shaped cross-section and its surface is fixedly connected to the upper surface of the cabinet 1. After the blower 81 is started, the input end of the blower 81 generates suction force through the exhaust pipe 83, which draws the debris, failed abrasive, and dust from the grinding pot 6, which are filtered and concentrated at the discharge pipe 79 through the perforation 78. The dust is then drawn into the exhaust pipe 83 through the corrugated pipe 84. The inner wall of the exhaust pipe 83 has a groove corresponding to the position of the collection box 85 and a filter screen 86 is fixed therein. Large particles of debris in the airflow are intercepted by the filter screen 86 and fall into the collection box 85 for collection. The airflow then continues to pass through the dust-proof sponge 87, which is a polyurethane open-pore sponge that can effectively adsorb fine dust particles, achieving secondary fine filtration and preventing dust from being directly discharged into the air, thus ensuring a clean working environment. Cleaning the collection box 85 is extremely convenient. The operator only needs to pull the limit bolt 881, which is slidably connected to the surface of the exhaust pipe 83. Its lower end slides through the limit plate 882 at the upper end of the collection box 85. When pulled, the limit bolt 881 compresses the spring 883 and disengages from the limit plate 882, so the collection box 85 can be removed from the exhaust pipe 83 to clean the internal dust. After cleaning, push the collection box 85 back, release the limit bolt 881, and the spring 883 resets, causing the limit bolt 881 to automatically insert into the limit plate 882 to complete the locking, realizing quick disassembly and replacement. During the polishing process, the connection between the corrugated pipe 84 and the discharge pipe 79 can be disconnected. The fan 81 can still operate at this time. Airflow enters the input end of the fan 81 through the exhaust pipe 83, and is then blown out by two air guide plates 82 at the output end of the fan 81. The air guide plates 82 have a C-shaped cross-section and their upper ends are fixedly connected to the top wall of the cabinet 1. The blown airflow forms air convection inside the cabinet 1, effectively carrying away the heat generated by the drive motor 3 and preventing overheating. Simultaneously, the intake airflow can also act on the outside of the polishing pot 6 to assist in heat dissipation, achieving airflow reuse and energy efficiency. After all operations are completed, the drive motor 3, servo motor 764, and fan 81 are turned off via the control panel 2, ending the polishing operation. This invention integrates efficient polishing, quick replacement, automatic cleaning, and ventilation and heat dissipation, significantly improving the overall performance and ease of operation of the polishing equipment.
