Description

Technical Field

[0001] This invention relates to the field of grinding wheel manufacturing equipment technology, and more particularly to a rotary three-mode fiber-reinforced resin grinding wheel forming machine. Background Technology

[0002] Existing grinding wheel manufacturing equipment can produce one grinding wheel per station rotation. For example, patent announcement number CN106041770B discloses a fully automatic rotary multi-station grinding wheel forming machine. This machine automates the entire process from feeding, scraping, adjustment, pressing, and finished product ejection, greatly improving equipment reliability and automation. Six molds are evenly arranged on the mold mounting frame, and one grinding wheel can be formed per rotation of the mold mounting frame.

[0003] Meanwhile, CN102699835B discloses a rotary multi-station grinding wheel forming machine. This machine adopts a multi-station operation mode, and around the working turntable, it is sequentially equipped with a mold unloading and blank handling device, a material feeding and stirring device, and a material scraping device. This subdivides the grinding wheel forming process into multiple operating stations, simplifying the unit actions and significantly improving product quality and efficiency. Eight grinding wheel molds are evenly arranged on the working turntable, and one grinding wheel can be produced per rotation of the turntable.

[0004] With the rapid development of grinding wheel forming technology, the industry's requirements for grinding wheel capacity, efficiency, and quality are also increasing. Therefore, equipment that can only produce one grinding wheel at a single rotating station is no longer sufficient to meet industry demands. Based on existing grinding wheel manufacturing equipment, a rotary three-modulus fiber-reinforced resin grinding wheel forming machine was developed to meet these industry needs.

Detailed Implementation

[0049] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings: like Figures 1-32 As shown, the rotary three-die fiber-reinforced resin grinding wheel forming machine is used for high-volume manufacturing of grinding wheels. The grinding wheel forming machine includes a base frame 1, a large turntable 2 circumferentially rotating above the base frame 1, and sixteen die holes 3 arranged circumferentially on the large turntable 2, as shown. Figure 1 and Figure 2 As shown. The base frame 1 is the steel structure foundation of the entire grinding wheel forming machine. The base frame 1 is a circular frame with a certain height.

[0050] The large turntable 2 is a circular plate. It is driven by a geared motor, which uses a pinion gear and a large gear ring for transmission, thus causing the turntable 2 to rotate circumferentially. To ensure the turntable 2 is positioned after each rotation, sixteen positioning blocks are arranged circumferentially around its edge. At least one positioning component 6 is also installed on the base frame 1. The positioning component 6 is driven by a positioning cylinder, which pushes a positioning bearing into the positioning block to achieve positioning of the turntable 2 after each rotation, preventing it from deflecting. The driving principle and structure of the large turntable 2, as well as its positioning principle and structure after rotation, can be found in patent publication CN210335280U, "A Mold Rotation Intermittent Displacement Mechanism," and will not be elaborated upon here.

[0051] A central column 7, cylindrical in shape, is vertically positioned at the center of the base frame 1. The central column 7 remains stationary and passes upwards through the center of the large turntable 2, allowing relative rotation between the central column 7 and the turntable 2. The mechanism by which the central column 7 passes through the turntable 2 can be found in the pressure forming mechanism of the grinding wheel forming machine disclosed in patent publication number CN205888926U, and will not be elaborated here. After passing upwards through the turntable 2, the central column 7 is connected to a mounting ring plate 8, which is horizontally positioned above the turntable 2 and is a semi-circular plate.

[0052] Each die group 3 on the large turntable 2 includes three circular die holes arranged in an equilateral triangle, with two die holes on the same circumference and the remaining die hole on another circumference. A grinding wheel die is bolted into each die hole, and forty-eight grinding wheel dies are mounted on the large turntable 2. The large turntable 2 drives the grinding wheel dies to rotate together.

[0053] Grinding wheel molds are existing technology; grinding wheel molds, such as... Figure 32 As shown, the grinding wheel mold includes a mold ring 4a and a mold base plate 4b with a mandrel 4c at its center. The mold ring 4a is a circular ring and is bolted into a mold hole. The mold base plate 4b is movably arranged within the mold hole. After the mold base plate 4b and the mandrel 4c are interference-fitted, their cross-section is "T"-shaped. The mold base plate 4b can be driven to rotate by external force and can also be moved up and down by external force. The grinding wheel mold also includes a mold cover 4d, which can be snapped downwards into the mold ring 4a and cooperates with the mandrel 4c. The structure of the grinding wheel mold can be referred to the mold in the double-cavity 48-station quick-change cutting disc forming machine of application number 2024202881830, and will not be described in detail here.

[0054] To better support the grinding wheel mold, a slide rail 9 is also provided on the base frame 1. There are two sets of slide rails 9, which are arranged in a concentric circle pattern. The two sets of slide rails 9 correspond to the two concentric circle positions where the mold hole is located. The slide rails 9 are arranged below the mold hole, so that the slide rails 9 can support the mold base plate 4b and ensure that the mold base plate 4b will not detach downward from the mold ring 4a.

[0055] like Figure 3 As shown, clockwise around the large turntable 2, the sixteen mold hole groups 3 correspond sequentially to the following stations: lifting station 10, waxing station 11, resetting station 12, screen placement station 13, screen measuring station 14, screen baking station 15, screen pressing station 16, material feeding station 17, material spreading station 18, screen placement station 29, screen measuring station 20, marking station 21, empty station 12, pressing station 23, empty station 24, and mold removal station 25. The mounting ring plate 8 is arranged clockwise between the resetting station 12 and the screen measuring station 20. The slide 9 does not pass through every mold hole. If there is a device at the corresponding station to support the grinding wheel mold, the slide 9 is not needed and thus the slide 9 is disconnected. Here, the slide 9 is not arranged at the pressing station 23, the mold removal station 25, the lifting station 10, the waxing station 11, the resetting station 12, the screen pressing station 16, and the material spreading station 18.

[0056] The large turntable 2 stops after rotating to each station, and is then positioned by the positioning component 6 to prevent it from deviating. After the large turntable 2 is positioned, the mechanical device at the corresponding station begins operation, carrying out the production process for that station. In this way, after the large turntable 2 rotates, the grinding wheel mold in each die group 3 passes through the aforementioned sixteen stations in sequence, thus producing three grinding wheels at once, thereby increasing the production output of grinding wheels.

[0057] The grinding wheel mold passes through the lifting station 10: The lifting station 10 is equipped with a post-unloading lifting device 26 connected and fixed to the base frame 1. This device 26 lifts the grinding wheel mold upwards. Specifically, the post-unloading lifting device 26 includes a fixed base plate 261, a fixed top plate 262, a guide rod 263, a lifting cylinder 264, a lifting plate 265, and a lifting rod assembly 266, as shown below. Figure 4 As shown. The fixed top plate 262 is connected and fixed to the base frame 1. The fixed top plate 262 and the fixed bottom plate 261 are arranged vertically at intervals. Three guide rods 263 are provided between the fixed top plate 262 and the fixed bottom plate 261, and the fixed top plate 262 and the fixed bottom plate 261 are connected and fixed through the three guide rods 263.

[0058] A lifting plate 265 slides vertically between the fixed top plate 262 and the fixed bottom plate 261. Three guide rods 263 pass through the lifting plate 265, which is horizontally arranged. Three linear bearings are installed on the lifting plate 265, and the linear bearings are slidably connected to the guide rods 263, allowing the lifting plate 265 to slide smoothly up and down. A lifting cylinder 264 is installed below the fixed bottom plate 261, and the lifting cylinder 264 is connected upward to the lifting plate 265 to control the up and down movement of the lifting plate 265. Three sets of ejector rods 266 are installed on the lifting plate 265, each set of ejector rods corresponding to the three mold holes in a mold hole group 3. Each set of ejector rods 266 includes three vertically arranged short ejector rods that pass upward through the fixed top plate 262 and abut against the mold bottom plate 4b.

[0059] Therefore, when the grinding wheel mold passes the lifting station 10, the grinding wheel mold stops on the fixed top plate 262, which supports the mold base plate 4b. After demolding, the lifting device 26 is activated: the lifting cylinder 264 moves, driving the lifting plate 265 upward, and the short ejector rods move upward simultaneously. Thus, the three short ejector rods can evenly lift the mold base plate 4b in the grinding wheel mold, causing the mold base plate 4b to move upward. Then the lifting cylinder 264 retracts, and the short ejector rods move downward and retract outside the grinding wheel mold.

[0060] The lifting station 10 is arranged between the mold removal station 25 and the waxing station 11 to prevent the grinding wheel from failing to be removed at the mold removal station 25. In this case, the post-mold removal lifting device 26 at the lifting station 10 can lift the grinding wheel again, allowing manual removal and thus handling the situation where the machine fails to remove the grinding wheel. At the same time, by lifting the mold base plate 4b upward by the lifting station 10, manual waxing can also be performed.

[0061] The grinding wheel mold passes through waxing station 11: Waxing station 11 is equipped with corresponding bottom plate waxing devices 27 and waxing lifting devices 30. The bottom plate waxing device 27 is mounted on the mounting ring plate 8. The bottom plate waxing device 27 rotates downwards to contact the grinding wheel mold. Specifically, the bottom plate waxing device 27 includes a waxing fixing plate 271, a waxing cylinder 272 vertically mounted on the waxing fixing plate 271, a motor mounting plate 273, and three waxing components 274 mounted on the motor mounting plate 273. The piston rod of the waxing cylinder 272 is connected to the motor mounting plate 273, which can drive the motor mounting plate 273 to move up and down horizontally. The waxing components 274 move along with it. Figure 5 As shown.

[0062] Each waxing assembly 274 includes a waxing motor 28 and a waxing disc 29 controlled by the waxing motor 28. The waxing disc 29 rotates downwards and contacts the mold ring 4a and the mold base plate 4b, thereby forming a wax layer on the surface of the grinding wheel mold. The waxing lifting device 30 is mounted on the base frame 1. The waxing lifting device 30 lifts the grinding wheel mold upwards, specifically lifting the mold base plate 4b. The waxing lifting device 30 has the same structure and operating principle as the demolding lifting device 26.

[0063] Therefore, when the grinding wheel mold passes the waxing station 11, the grinding wheel mold stops on the waxing lifting device 30, which supports the mold base plate 4b. The waxing lifting device 30 is activated, lifting the mold base plate 4b upwards again via a short ejector rod. Simultaneously, the base plate waxing device 27 is activated, with the waxing cylinder 272 driving the three waxing components 274 downwards. The waxing motor 28 drives the rotating waxing disc 29 to wax the surface of the mold base plate 4b, facilitating subsequent demolding of the grinding wheel. Then, the waxing lifting device 30 moves downwards, the mold base plate 4b falls, the waxing cylinder 272 rises, and the waxing disc 29 no longer contacts the mold base plate 4b.

[0064] The grinding wheel mold passes through reset station 12: this station can cause the mold base plate 4b to return to its initial state. Reset station 12 is equipped with corresponding upper and lower pressure plate devices 31 and reset lower support components 32. Figure 6As shown. The bottom plate device 31 is installed on the mounting ring plate 8. The bottom plate device 31 presses the grinding wheel mold downward. Specifically, the bottom plate device 31 includes a support beam 311 and three bottom-pressing cylinders 312 installed on the support beam 311. The support beam 311 is installed on the mounting ring plate 8. One end of the support beam 311 is connected to the central column 7. Each bottom-pressing cylinder 312 is vertically connected to a pressure plate 313. The bottom-pressing cylinder 312 can drive the pressure plate 313 to move up and down, thereby using the pressure plate 313 to press the mold bottom plate 4b, causing the mold bottom plate 4b to return to the lowest position within the mold ring 4a.

[0065] The reset lower support assembly 32 ensures that the mold base plate 4b is prevented from detaching from the mold ring 4a when the mold base plate 4b is clamped. The reset lower support assembly 32 is mounted on the base frame 1 and abuts against the grinding wheel mold upwards to support the mold base plate 4b. The reset lower support assembly 32 includes a lower pad plate 321, a heating plate 322, and a heat insulation plate 323 arranged sequentially from top to bottom. The lower pad plate 321 is in contact with the mold base plate 4b. The entire reset lower support assembly 32 is connected to the base frame 1 through a lower support seat with a "II" shaped cross-section.

[0066] Therefore, when the grinding wheel mold passes the reset station 12, the grinding wheel mold stops on the reset lower support assembly 32, and the mold base plate 4b is supported by the lower pad 321. The bottom plate pressing device 31 is activated, and the bottom pressing cylinder 312 drives the pressing plate 313 to move down. The three pressing plates 313 press the mold base plates 4b in the three grinding wheel molds, causing the mold base plates 4b that were originally raised to reset downwards, ensuring that the mold base plates 4b are arranged flat at the lowest position of the mold ring 4a. Then the pressing plate 313 moves up and removes the grinding wheel mold without interfering with the operation of the large turntable 2.

[0067] The grinding wheel mold passes through the mesh feeding station 13: This station allows fiberglass mesh to be fed into the grinding wheel mold. The mesh feeding station is equipped with corresponding mesh separation and pickup devices 33 and mesh stack storage platforms 36. The mesh separation and pickup devices 33 pick up the mesh from the mesh stack storage platforms 36 and deliver it into the grinding wheel mold. Figure 7 As shown.

[0068] The wire mesh stack storage platform 36 is mounted on the base frame 1. The wire mesh stack storage platform 36 includes a wire mesh frame 361, a rodless cylinder 362, a wire mesh changing slide plate 363 controlled by the rodless cylinder 362, two sets of stacking assemblies, and a top wire mesh assembly 37. Figure 8 and Figure 9 As shown, the mesh frame 361 has a double-layer frame structure. A rodless cylinder 362 is horizontally mounted on the mesh frame 361. The rodless cylinder 362 is connected to the mesh changing slide plate 363, which can drive the mesh changing slide plate 363 to reciprocate. The mesh changing slide plate 363 is slidably connected to the mesh frame 361 via a slide rail slider, improving the smoothness of the movement of the mesh changing slide plate 363.

[0069] Because there are two sets of stacking components, and one set of stacking components is set on each side of the screen changing slide 363, the screen changing slide 363 can drive the two sets of stacking components to move simultaneously. The two sets of stacking components are used and one is on standby. That is, when one set of stacking components is working with the screen separation and picking device 33, the operator can add screens to the other set of stacking components for use. In this way, fiberglass screens can be added without stopping the machine, so as to achieve continuous operation of the equipment.

[0070] The stacking assembly includes three mesh-passing units 38, each of which includes a centering rod 381, a damping sleeve 382, ​​and a mesh support plate 383. The centering rod 381 is vertically mounted on the mesh-changing slide plate 363. The damping sleeve 382 is coaxially mounted on the upper end of the centering rod 381. The damping sleeve 382 is a conical ring that is thin at both ends and thick in the middle. The maximum diameter of the damping sleeve 382 is larger than the diameter of the centering rod 381, which facilitates the separation of mesh sheets one by one. The damping sleeve 382 has multiple long grooves, which are arranged circumferentially on the damping sleeve 382. The long grooves extend downward from the top surface of the damping sleeve 382 and are close to the bottom surface of the damping sleeve 382.

[0071] A mesh support plate 383 is fitted onto the centering rod 381. The mesh support plate 383 slides down the centering rod 381. Several fiberglass mesh sheets are fitted onto the centering rod 381 and supported by the mesh support plate 383, thus forming a mesh stack. The mesh stack assembly moves upward, and the mesh sheets move upward one by one from the centering rod 381 through the damping sleeve 382. The upward movement of the mesh stack is achieved by the top mesh assembly 37.

[0072] The top mesh assembly 37 is located below the mesh platform 361. The top mesh assembly 37 is arranged below a set of stacking assemblies, and the installation position of the top mesh assembly 37 is fixed. There are three top mesh assemblies 37, and each of the three top mesh assemblies 37 corresponds one-to-one with the three mesh-passing units 38 in the set of stacking assemblies. The top mesh assembly 37 is used to cause the mesh support plate 383 to move upward, thereby lifting the mesh stack.

[0073] Each top net assembly 37 includes a hanger 371, a lifting slider 372, and long top rods 373. The hanger 371 has a U-shaped cross-section and is fixedly connected to the net frame 361. A top net cylinder 374 is installed below the hanger 371, and the lifting slider 372 is slidably connected above the hanger 371. The lifting slider 372 is connected to the top net cylinder 374 and can drive the lifting slider 372 to move up and down. Three long top rods 373 are arranged circumferentially above the lifting slider 372. The long top rods 373 pass upward through the net changing slide plate 363 and abut against the bottom of the net support plate 383. The long top rods 373 can lift the net support plate 383 up and down.

[0074] The mesh separation and pickup device 33 is mounted on the mounting ring plate 8. The mesh separation and pickup device 33 includes a mesh linear module 331 and a pickup mechanism 332 controlled by the mesh linear module 331. Figure 10 As shown. The wire mesh linear module 331 adopts a synchronous belt module. The wire mesh linear module 331 can drive the picking mechanism 332 to reciprocate horizontally between the stacking assembly and the grinding wheel mold, thereby facilitating the picking of wire mesh and its delivery into the grinding wheel mold.

[0075] The pickup mechanism 332 includes a pickup cylinder 34 and three belt pickup units 35 controlled by the pickup cylinder 34. The pickup cylinder 34 drives the three belt pickup units 35 to move up and down synchronously. The three belt pickup units 35 are mounted on a connecting plate 93, which is connected to the piston rod of the pickup cylinder 34.

[0076] Three tape-type pickup units 35 pick up the wire mesh from three wire mesh-threading units 38 in the same stacking unit. One tape-type pickup unit 35 operates independently and is equipped with its own power source. The other two tape-type pickup units 35 share a side frame 39 and are driven by a single power source. Taking the coordinated operation of the other two tape-type pickup units 35 as an example, its structure is explained as follows: tape-type pickup units 35 are arranged at both ends of the side frame 39, and a drive cylinder 40 is arranged in the middle of the side frame 39. The drive cylinder 40 simultaneously drives the two tape-type pickup units 35 to rotate.

[0077] The tape pickup unit 35 includes an unwinding shaft 401, a rewinding shaft 402, a tape 403, a guide block 404, a wire retraction cylinder 405, and a wire retraction plate 406 controlled by the wire retraction cylinder 405. Figures 11-13 As shown. An unwinding shaft 401 is fixedly mounted on a side frame 39. Unwinding rollers 41 are rotatably connected to both ends of the unwinding shaft 401, passing through the side frame 39. The outer contour of the unwinding rollers 41 is a quadrangular prism with rounded corners. A roll of fiberglass-reinforced adhesive tape 403 is fitted onto the unwinding rollers 41. The tape 403 is interference-fitted with the unwinding rollers 41, allowing them to rotate together. A nut is threaded onto the end of the unwinding shaft 401, and a brake pad 43 is fitted onto the end of the unwinding shaft 401. Tightening the nut compresses the brake pad 43, ensuring tight contact between the brake pad 43 and the unwinding rollers 41, preventing the unwinding rollers 41 from rotating easily.

[0078] The take-up shaft 402 is rotatably connected to the side frame 39 via a bearing seat. Both ends of the take-up shaft 402 are keyed to take-up rollers through the side frame 39. The take-up rollers have a "T" shaped cross section. The end of the take-up shaft 402 is threaded with a locking cap 44. A retaining ring 45 is also fitted at the end of the take-up shaft 402. After tightening the locking cap 44, the retaining ring 45 is pressed tightly against the end of the take-up roller. After the take-up roller and the retaining ring 45 are connected and combined, the cross section is in the shape of an I-beam.

[0079] Rectangular guide blocks 404 are installed on both sides below the side frame 39. The two ends of the guide blocks 404 are bent into semi-circles. The guide blocks 404 are located below the take-up shaft 402 and the unwind shaft 401. The tape 403 is led out, passes around a corresponding guide block 404, and connects to the corresponding take-up roller. There are two such arrangements of tape 403 in one tape pickup unit 35. The tape 403 on the unwind shaft 401 is used for release, and the take-up shaft 402 is used for rewinding the tape 403 after release.

[0080] Note that in the two tape pickup units 35 on the side frame 39, the take-up shafts 402 are close to each other, while the unwinding shafts 401 are far apart. A spur gear 46 is connected to the take-up shaft 402 via a one-way bearing. Simultaneously, a vertically arranged rack 47 is connected to the piston rod of the drive cylinder 40, positioned between the spur gears 46 on the two take-up shafts 402. The rack 47 has teeth machined on both ends, allowing it to mesh with both spur gears 46 simultaneously. When the rack 47 moves downwards, the one-way bearing rotates, while the take-up shaft 402 remains stationary. When the rack 47 moves upwards, the one-way bearing drives the take-up shaft 402 to rotate counterclockwise, thus winding the tape 403 onto the take-up roller. In short, each up-and-down reciprocation of the rack 47 allows the tape 403 on the unwinding roller 41 to release a certain length and the tape 403 on the winding roller to wind up a certain length, thereby achieving the renewal of the tape 403 at the guide block 404 position and ensuring the adhesion to the mesh.

[0081] The fiberglass mesh, positioned at guide block 404, is secured between the two guide blocks 404 by the adhesive force of the two tapes 403, enabling mesh pickup. However, during mesh feeding, a mesh retraction cylinder 405 is arranged within the side frame 39. The retraction cylinder 405 is located between the unwinding shaft 401 and the rewinding shaft 402. A mesh retraction plate 406, a circular perforated plate, is connected downwards to the cylinder. This plate is positioned to accommodate the guide blocks 404 and the damping sleeve 382, ​​and surrounds the two guide blocks 404. The downward movement of the retraction plate 406 causes the mesh to detach from the adhesive tapes 403, moving it downwards away from the guide blocks 404.

[0082] Therefore, when the grinding wheel mold passes the mesh placement station, the grinding wheel mold stops on the slide rail 9, which supports the mold base plate 4b. The top mesh assembly 37 moves upward, causing the mesh stack to move upward, ensuring that the top layer of the mesh stack is close to the damping sleeve 382; the pickup cylinder 34 moves downward, driving the tape pickup unit 35 downward, using the tape 403 at the guide block 404 to adhere the top mesh of the mesh stack, and then the pickup cylinder 34 moves upward, driving the mesh past the damping sleeve 382 and detaching it from the centering rod 381. The damping sleeve 382 ensures that only one mesh detaches from the centering rod 381 at a time. The mesh straightening module 331 drives the tape pickup unit 35 to move above the grinding wheel mold, and then the pickup cylinder 34 drives the mesh downward, and the mesh removal cylinder 405 moves downward, driving the mesh removal plate 406 downward, causing the mesh to detach from the guide block 404, thereby sending the mesh head into the grinding wheel mold.

[0083] The grinding wheel mold passes through measuring station 14: Measuring station 14 is equipped with a measuring device 48, connected and fixed to the mounting ring plate 8, used to detect the presence or absence of a mesh inside the grinding wheel mold. The measuring device 48 includes a measuring frame 481 and three measuring sensors 482 connected to the measuring frame 481, such as... Figure 14 As shown. The mesh measuring sensor 482 is a color mark sensor or a vision camera, which can determine the presence of the mesh. When the grinding wheel mold passes through the mesh measuring station 14, the mold base plate 4b is supported by the slide 9.

[0084] The grinding wheel mold passes through the baking rack station 15: At the baking rack station 15, a baking rack device 49 is arranged and fixed to the mounting ring plate 8. The baking rack device 49 includes a baking rack fixing plate 491, a baking rack cylinder 492, a baking rack lifting plate 493, and baking rack covers 494. The baking rack fixing plate 491 is equipped with the baking rack cylinder 492, which is vertically connected to the baking rack lifting plate 493. Three baking rack covers 494 are arranged circumferentially on the baking rack lifting plate 493. Each baking rack cover 494 contains a heating plate for an electric ceramic kiln. Figure 14 As shown. The baking mesh cover 494 is moved downward by the baking mesh cylinder 492, causing the baking mesh cover 494 to cover the grinding wheel mold. The glass fiber mesh is heated by the heating plate of the electric ceramic furnace. When the grinding wheel mold passes through the baking mesh station 15, the mold base plate 4b is supported by the slide 9.

[0085] The grinding wheel mold passes through the mesh pressing station 16: At the mesh pressing station 16, corresponding upper and lower mesh pressing devices 50 and mesh pressing lower support components 51 are arranged. The mesh pressing device 50 is set on the mounting ring plate 8. The mesh pressing device 50 presses the mesh sheet inside the grinding wheel mold downward. Specifically, the mesh pressing device 50 includes a mesh pressing fixing plate 501, a mesh pressing cylinder 502, and a mesh pressing disc 503. The mounting ring plate 8 protrudes outward to form the mesh pressing fixing plate 501. Three mesh pressing cylinders 502 are set on the mesh pressing fixing plate 501. Each mesh pressing cylinder 502 is vertically and elastically connected to the mesh pressing disc 503. The elastic connection is achieved by a compression spring, so the mesh pressing disc 503 can elastically press the mesh sheet.

[0086] The lower support assembly 51 for pressing the mesh is mounted on the base frame 1. The lower support assembly 51 for pressing the mesh and the lower support assembly 32 for resetting have the same structure. The lower support assembly 51 for pressing the mesh abuts upwards against the grinding wheel mold. Figure 15 As shown, when the grinding wheel mold passes the mesh pressing station 16, the grinding wheel mold stops on the mesh pressing lower support component 51, which supports the mold base plate 4b. The mesh pressing device 50 is activated, and the mesh pressing cylinder 502 drives the mesh pressing disc 503 to move down and press the mesh into the grinding wheel mold.

[0087] The grinding wheel molds pass through feeding station 17: this station adds resin-bonded abrasive wheels into the grinding wheel molds. Feeding station 17 is equipped with a connected raw material vibrating plate 52 and a feeding device 53. The raw material vibrating plate 52 contains the resin-bonded abrasive wheels and is connected downwards to the base frame 1 to ensure its fixed installation. The feeding device 53 is mounted on the mounting ring plate 8, and the abrasive wheel material in the raw material vibrating plate 52 flows evenly into the three grinding wheel molds through the feeding device 53.

[0088] The feeding device 53 includes a mixing tank 531 with an open top, three on / off valves 532 arranged circumferentially at the bottom of the mixing tank 531, three baffle hoppers 533 arranged circumferentially below the mixing tank 531, and a material guiding assembly 534 arranged below the mixing tank 531. Figures 16-20 As shown. The mixing tank 531 is a circular tank. The raw material vibrating plate 52 is connected to the mixing tank 531. A stirring motor 60 is installed above the mixing tank 531. The output shaft of the stirring motor 60 is located at the center of the mixing tank 531. The output shaft of the stirring motor 60 extends downward into the mixing tank 531 and is connected to a material brush 61. There are at least two material brushes 61. The material brushes 61 are arranged radially along the mixing tank 531 and are in contact with the inner wall of the mixing tank 531.

[0089] Three rectangular discharge ports 62 are provided at the bottom of the mixing tank 531. Each discharge port 62 is equipped with an on / off valve 532, which controls the size of the discharge port 62. The on / off valve 532 includes an adjusting base plate 54, an adjusting baffle 55, and an adjusting screw 56. The adjusting base plate 54 is fixedly connected to the bottom of the mixing tank 531. The adjusting baffle 55 is slidably connected above the adjusting base plate 54 and is inserted into the discharge port 62. The adjusting screw 56 is threaded onto the adjusting base plate 54, and one end of the adjusting screw 56 is rotatably connected to the adjusting baffle 55. By manually operating the adjusting screw 56 to move the adjusting baffle 55, the size of the discharge port 62 can be changed.

[0090] The raw materials in the mixing tank 531 fall downwards into the baffle hopper 533. The baffle hopper 533 corresponds one-to-one with the on / off valve 532. The mixing tank 531 is connected to the baffle hopper 533 downwards through the on / off valve 532. The lower end of the baffle hopper 533 is shaped like a truncated pyramid. A cover plate 63 is rotatably installed inside the baffle hopper 533 to block the on / off valve 532, that is, the cover plate 63 can be used to close the discharge port 62. Specifically, a rotating block 64 is rotatably arranged below the adjusting base plate 54 of each on / off valve 532. One end of the rotating block 64 extends into the baffle hopper 533 and is connected and fixed to the cover plate 63. One side wall of the baffle hopper 533 is open, so as not to affect the rotation of the rotating block 64.

[0091] Here, a tilting cylinder 65 is used to rotate the cover plate 63. Since there are three cover plates 63, one cover plate 63 is controlled by a single tilting cylinder 65, while the other two cover plates 63 are controlled by a single tilting cylinder 65. Specifically, a connecting rod 66 is set between the rotating blocks 64 of the other two cover plates 63. The tilting cylinder 65 is hinged, and its piston rod is connected to the connecting rod 66 through a fisheye bearing. Through the extension and retraction of the tilting cylinder 65, the cover plate 63 can be rotated up and down. Rotating the cover plate 63 upward closes the discharge port 62, and rotating it downward opens the discharge port 62.

[0092] The raw material in the baffle 533 flows into the grinding wheel mold after passing through the guide assembly 534. The guide assembly 534 includes a guide cylinder 57, a guide frame 58 controlled by the guide cylinder 57, and three guide hoppers 59 arranged circumferentially on the guide frame 58. The guide cylinder 57 is installed below the mixing tank 531. The baffle hopper 533 and the guide hoppers 59 correspond one-to-one and are connected vertically. The guide hoppers 59 are conical in shape.

[0093] Therefore, when the grinding wheel mold passes the feeding station 17, it stops on the slide rail 9, which supports the mold base plate 4b. The raw material vibrating plate 52 delivers a certain amount of raw material into the mixing tank 531. The cover plate 63 is closed at first, and the mixing motor 60 drives the material brush 61 to rotate, thereby promoting the uniformity of the raw material in the mixing tank 531. Then the cover plate 63 is opened, and with the rotation of the material brush 61, the raw material is evenly guided into the grinding wheel mold through the discharge port 62, the baffle hopper 533, and the guide hopper 59, realizing the feeding operation.

[0094] The grinding wheel mold passes through the material spreading station 18: The material spreading station 18 is equipped with corresponding servo scraping devices 67 and material spreading turntables 68. The servo scraping devices 67 are set on the mounting ring plate 8 and extend downward into the grinding wheel mold. In conjunction with the rotating grinding wheel mold, the servo scraping devices 67 can evenly scrape the raw material in the mold.

[0095] The servo scraping device 67 includes a servo electric cylinder 671, a scraper seat 672 controlled by the servo electric cylinder 671, and three scrapers 673 arranged circumferentially on the scraper seat 672, such as Figure 21 and Figure 22 As shown. The servo electric cylinder 671 is vertically connected to the mounting ring plate 8. The servo electric cylinder 671 can drive the scraper seat 672 to move up and down. The servo electric cylinder 671 has the advantage of high operating precision. Each scraper 673 is vertically adjustable to the scraper seat 672 to change the height position of the scraper 673. Specifically, the scraper 673 is mounted on the fixed frame 69. The fixed frame 69 is slidably connected to the scraper seat 672 through a linear bearing and guide rod structure. The fixed frame 69 can move up and down. The scraper seat 672 is provided with a star-shaped handle 70, which is threadedly connected to the scraper seat 672 and also threadedly connected to the fixed frame 69.

[0096] The material spreading turntable 68 is used to drive the mold base plate 4b to rotate. The material spreading turntable 68 is mounted on the base frame 1 and drives the grinding wheel mold to rotate. The material spreading turntable 68 includes a material spreading motor 681 and three turntable panels 682 controlled by the material spreading motor 681. Specifically, a gearbox 683 is mounted on the base frame 1. Inside the gearbox 683, there is a large gear and three small gears arranged circumferentially around the large gear and meshing with it. The material spreading motor 681 is mounted at the bottom of the gearbox 683, and the output shaft of the material spreading motor 681 meshes with the large gear. Three large bearing seats 684 are set above the gearbox 683. A turntable panel 682 is rotatably connected to each large bearing seat 684. The turntable panel 682 has a "T" shaped cross section. The lower end of the turntable panel 682 is connected to the corresponding small gear. Driven by the material spreading motor 681 and under the meshing of the large and small gears, the three turntable panels 682 can be rotated synchronously, thereby driving the mold base plate 4b to rotate.

[0097] Therefore, when the grinding wheel mold passes the spreading station 18, the grinding wheel mold stops on the spreading turntable 68, and the mold base plate 4b is supported by the turntable panel 682. The spreading motor 681 starts and drives the mold base plates 4b in the three grinding wheel molds to rotate simultaneously through gear transmission. At the same time, the servo electric cylinder 671 drives the scraper 673 to move down, causing the scraper 673 to extend into the mold ring 4a, and with the cooperation of the rotating mold base plate 4b, the raw material can be evenly scraped flat.

[0098] The grinding wheel mold passes through the mesh feeding station 2 19: the mesh feeding station 2 19 is also equipped with corresponding mesh separation and picking devices 33 and mesh stacking storage devices, and glass fiber mesh is put into the grinding wheel mold again.

[0099] The grinding wheel mold passes through the measuring station 20: The measuring station 20 is also equipped with a measuring device 48 connected to the mounting ring plate 8 for detecting whether there is a mesh inside the grinding wheel mold.

[0100] The grinding wheel mold passes through marking station 21: This station is used to place label paper and core rings into the grinding wheel mold. Marking station 21 is equipped with a core ring vibrating plate 71, a core ring label storage platform 72, and a core ring label pickup device 76. The core ring vibrating plate 71 delivers core rings to the core ring label storage platform 72, and the core ring label pickup device 76 picks up the core rings and labels from the core ring label storage platform 72 and delivers them into the grinding wheel mold. Figure 23 As shown.

[0101] The core ring and label storage table 72 is mounted on the base frame 1, and can store core rings and label papers simultaneously. The core ring and label storage table 72 includes a storage frame 73 and core ring storage mechanism 74 and label storage mechanism 75 respectively disposed on both sides of the storage frame 73. The storage frame 73 is a double-layer plate frame structure.

[0102] The core ring storage mechanism 74 includes a rotating disk 741, a through rod 742, a washer 743, and a core ring lifting assembly 744, such as Figure 24 and Figure 25As shown, a rotating disk 741 is rotatably mounted on the storage platform 73. Specifically, the indexing box 80 is driven by a motor and a chain drive, which in turn drives the rotating disk 741 to rotate. The rotating disk 741 has six through rods 742 arranged circumferentially. Three of the six through rods 742 form a group, for a total of two groups. One group of through rods 742 is in standby mode, allowing for operation without stopping the machine. Each through rod 742 has a pad 743 inserted into it. The core ring is dropped onto the through rod 742 by the core ring vibrating plate 71, and the pad 743 supports the core ring. The storage platform 73 below the three through rods 742 is equipped with a core ring lifting assembly 744. The core ring lifting assembly 744 lifts the pad 743 upward. The operating principle and structure of the core ring lifting assembly 744 are similar to the top net assembly 37 at the net laying station 13. Both use a cylinder to drive the rod to move upward and lift the pad 743. This will not be described in detail here.

[0103] The trademark storage mechanism 75 includes three trademark threading rods 751, trademark trays 752, and trademark lifting components 753. Each trademark threading rod 751 has a trademark tray 752 threaded onto it, and a damping sleeve 382 is also arranged at the upper end of each rod. Several trademark papers are threaded onto the trademark threading rods 751 to form a trademark stack, which is supported by the trademark trays 752. A trademark lifting component 753 is installed on a storage platform 73 below each trademark threading rod 751, which lifts the trademark tray 752 upwards. The operating principle and structure of the trademark lifting component 753 are similar to those of the top net component 37 at the netting station 13, and will not be described in detail here.

[0104] The core ring label pickup device 76 is mounted on the mounting ring plate 8. The core ring label pickup device 76 includes a horizontal linear module 77, a core ring pickup unit 78, and a label pickup unit 79, such as... Figure 26 and Figure 27 As shown. The horizontal linear module 77 adopts a synchronous belt module. The horizontal linear module 77 is equipped with a core ring pickup unit 78 and a trademark pickup unit 79. The horizontal linear module 77 can drive the two pickup units to move horizontally at the same time.

[0105] Both the core ring pickup unit 78 and the label pickup unit 79 include cylinders. The cylinder of the core ring pickup unit 78 is connected to three hollow cylindrical pickup heads 81. Each pickup head 81 has a magnet sliding vertically inside. Under normal conditions, the magnets rely on their own weight to be located at the lower end of the pickup head 81, thus attracting the core ring. When the pickup head 81 places the core ring into the grinding wheel mold, as the pickup head 81 moves downward, the mandrel 4c of the grinding wheel mold inserts upward into the pickup head 81 and pushes up the magnet. Consequently, the magnet moves away from the core ring and no longer attracts it, and the core ring falls onto the mandrel 4c. Simultaneously, each pickup head 81 is equipped with a proximity switch 82 at its lower part to detect whether a core ring has been attracted. The cylinder of the label pickup unit 79 is connected to three hollow pickup cylinders 83. The pickup cylinders 83 are connected to a negative pressure air source via air pipes. Each pickup cylinder 83 has three small suction cups 831 connected to its lower end, which are used to pick up the label paper.

[0106] Therefore, when the grinding wheel mold passes the label ring station 21, the grinding wheel mold stops on the slide rail 9, which supports the mold base plate 4b. The core ring label picking device 76 is activated, and two cylinders simultaneously drive the picking head 81 and the picking cylinder 83 downward. The picking head 81 magnetically attracts the core ring, and the picking cylinder 83 uses negative pressure to pick up the label paper. Then the cylinder moves upward. The horizontal linear module 77 drives the picking head 81 and the picking cylinder 83 back to above the grinding wheel mold. The picking cylinder 83 first moves downward to put the label paper into the grinding wheel mold. After the horizontal linear module 77 moves again, the picking head 81 moves downward to put the core ring into the grinding wheel mold.

[0107] No mechanical devices are installed at empty workstations 22 and 24. The grinding wheel mold passes through pressing workstation 23: Pressing workstation 23 is equipped with a press 92, which presses the raw material, wire mesh, core ring, and label paper into a single grinding wheel. Press 92 includes a press frame, a main hydraulic cylinder 85, a floating hydraulic cylinder 86, an upper press head assembly 87 with a press head, and a lower press support assembly 88. The press frame is vertically arranged and fixed to the central column 7. Specifically, the press frame includes an upper crossbeam 841, a lower crossbeam 842, and side columns 843. The upper crossbeam 841 and lower crossbeam 842 are arranged horizontally, with the upper crossbeam 841 positioned above the large turntable 2. The lower crossbeam 842 is embedded in the base frame 1 and contacts the ground. The lower crossbeam 842 and the upper crossbeam 841 are connected and fixed by two side columns 843. Simultaneously, the two ends of the central column 7 are also connected to the upper crossbeam 841 and the lower crossbeam 842, respectively. Figure 28 and Figure 29 As shown.

[0108] A main hydraulic cylinder 85 is mounted on the press frame, and a floating hydraulic cylinder 86 is connected downwards from the main hydraulic cylinder 85. The structure and principle of the floating hydraulic cylinder 86 can be found in the resin grinding wheel molding pressure balancing floating hydraulic cylinder 86 device disclosed in patent publication number CN217293577U, and will not be repeated here. An upper pressure head assembly 87 is mounted on the floating hydraulic cylinder 86. Three upper pressure head assemblies 87 are arranged above the large turntable 2. The floating hydraulic cylinder 86 ensures that the three upper pressure head assemblies 87 have the same pressure, achieving balanced pressing of the three grinding wheels. The pressure head installed on the upper pressure head assembly 87 is the mold cover 4d. The press lower support assembly 88 is arranged on the base frame 1 below the large turntable 2. The structure of the press lower support assembly 88 is the same as that of the reset lower support assembly 32. The press lower support assembly 88 reliably supports the grinding wheel mold, and the main oil cylinder 85 and the floating oil cylinder 86 cooperate to achieve the pressing and forming of the grinding wheel, and can ensure the balanced pressure of the three grinding wheels formed in one step.

[0109] When the grinding wheel passes through the mold removal station 25: The mold removal station 25 is equipped with a mold removal lifting device 89, a grinding wheel unloading device 90, and a belt conveyor 91. The mold removal lifting device 89 is mounted on the base frame 1. The mold removal lifting device 89 lifts the grinding wheel mold upward. The structure and principle of the mold removal lifting device 89 are the same as those of the mold removal lifting device 26. The difference is that the lifting power of the mold removal lifting device 89 is a hydraulic cylinder instead of a pneumatic cylinder.

[0110] The grinding wheel unloading device 90 is connected and fixed to the frame of the press 92. The grinding wheel unloading device 90 picks up the grinding wheel pressed into shape in the grinding wheel mold and delivers it to the belt conveyor 91. The grinding wheel unloading device 90 includes an unloading screw module 901 and an unloading plate 902 controlled by the unloading screw module 901, such as... Figure 30 and 31 As shown. The ejector screw module 901 drives the ejector plate 902 to move horizontally and reciprocally between the grinding wheel mold and the belt conveyor 91. The ejector plate 902 is equipped with three ejector cylinders 903, each of which is connected downward to a suction cup mounting plate 904. The suction cup mounting plate 904 is circumferentially equipped with multiple suction cups. The suction cups rely on negative pressure to firmly adsorb the grinding wheel and bring it out of the grinding wheel mold.

[0111] This invention utilizes a large turntable 2 to continuously rotate the grinding wheel mold. As the grinding wheel mold passes through different workstations, the corresponding mechanical equipment starts operating. After the grinding wheel mold has passed through sixteen workstations, one grinding wheel production process is completed, allowing for the production of three grinding wheels at a time. With the continuous operation of the grinding wheel mold, grinding wheels can be manufactured in large quantities with high capacity.

[0112] This invention is a three-cavity, multi-station rotary automatic grinding wheel forming machine. Each station is equipped with a three-hole mold mounting position and three sets of grinding wheel molds. Driven by a geared motor and in cooperation with the collaborative positioning component 6, the large turntable 2 operates intermittently in an indexing manner. A press 92 is equipped with three pressure heads, simultaneously pressing three grinding wheels. The automated mechanical equipment at each station has a combined structure, which can meet the requirements of the three-cavity design.

[0113] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present invention should be included within the scope of the present invention.
