DETAILED DESCRIPTION

[0049] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings: like Figure 1 to Figure 32 As shown, the rotary three-die fiber reinforced resin grinding wheel forming machine is used for high-volume manufacturing and forming of grinding wheels. The grinding wheel forming machine comprises a base frame 1, a large turntable 2 which is arranged on the base frame 1 in a circular rotation, and sixteen die hole groups 3 which are arranged on the large turntable 2 in an annular direction. Figure 1 and Figure 2 The base frame 1 is the steel structure foundation of the entire grinding wheel forming machine, and the base frame 1 is a circular frame with a certain height.

[0050] The large turntable 2 is a circular plate body. The large turntable 2 is driven by a reduction motor and driven by a small gear and a large gear ring meshing transmission, thereby driving the large turntable 2 to rotate in a circle. In order to ensure the positioning of the large turntable 2 after each rotation of a certain angle, sixteen positioning blocks are provided in the circumferential direction of the edge of the large turntable 2. At the same time, at least one positioning component 6 is provided on the chassis 1. The positioning component 6 is a positioning bearing driven by a positioning cylinder to be inserted into the positioning block to achieve the positioning of the large turntable 2 after each rotation of a certain angle, thereby preventing the large turntable 2 from deflecting. Here, the driving principle and structure of the large turntable 2, and the positioning principle and structure after rotation can refer to the patent publication number CN210335280U, a mold rotation intermittent displacement mechanism, which will not be repeated here.

[0051] A central column 7 is vertically arranged at the center of the base frame 1. The central column 7 is a cylinder. The central column 7 is fixed and moves upward through the center of the large turntable 2, so that the central column 7 and the large turntable 2 can produce relative rotation. How the central column 7 passes through the large turntable 2 can refer to the grinding wheel forming machine pressure forming mechanism disclosed in patent publication number CN205888926U, which will not be repeated here. After the central column 7 passes through the large turntable 2 upward, it is connected to a mounting ring plate 8, which is horizontally arranged above the large turntable 2, and the mounting ring plate 8 is a semicircular plate body.

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

[0053] The grinding wheel die is prior art. As shown in Fig.32 , the grinding wheel die includes a die ring 4a and a die bottom plate 4b with a mandrel 4c in the center. The die ring 4a is a toroidal body. The die ring 4a is bolted inside the die hole, and the die bottom plate 4b is movably arranged inside the die hole. After the die bottom plate 4b and the mandrel 4c are interference-connected, the cross-section is in the shape of "丄". The die bottom plate 4b can be driven to rotate by an external force, and the die bottom plate 4b can be driven to move up and down by an external force. At the same time, the grinding wheel die also includes a die cover 4d. The die cover 4d can be buckled downward inside the die ring 4a and cooperate with the mandrel 4c. The structure of the grinding wheel die can refer to the die in the dual-cavity 48-station quick-change cutting disc forming machine with the application number 2024202881830, which will not be elaborated here.

[0054] To better support the grinding wheel die, slideways 9 are also arranged on the chassis 1. There are two groups of slideways 9, and the two groups of slideways 9 are arranged in the form of inner and outer concentric circles. The two groups of slideways 9 respectively correspond to the two concentric circle positions where the die holes are located. The slideways 9 are arranged below the die holes. Thus, the slideways 9 can support the die bottom plate 4b to ensure that the die bottom plate 4b does not脱离 the die ring 4a downward.

[0055] As shown in Figure 3 , clockwise around the large turntable 2, sixteen die hole groups 3 sequentially correspond to a jacking station 10, a waxing station 11, a resetting station 12, a first mesh placing station 13, a first mesh measuring station 14, a mesh baking station 15, a mesh pressing station 16, a feeding station 17, a material spreading station 18, a second mesh placing station 19, a second mesh measuring station 20, a marking ring station 21, a first empty station 22, a pressing station 23, a second empty station 24, and a die unloading station 25. The mounting ring plate 8 is arranged clockwise between the resetting station 12 and the second mesh measuring station 20. The slideways 9 do not pass through every die hole. If there is a device at the corresponding station to support the grinding wheel die, there is no need to arrange the slideways 9. Thus, the slideways 9 are disconnected. Here, the slideways 9 are not arranged at the pressing station 23, the die unloading station 25, the jacking station 10, the waxing station 11, the resetting station 12, the mesh pressing station 16, and the material spreading station 18.

[0056] After the large turntable 2 rotates to a station, it stops and is then positioned by the positioning assembly 6 to prevent the large turntable 2 from deflecting. After the large turntable 2 is positioned, the mechanical device of the corresponding station starts to operate and carry out the production operation process of the current station. In this way, after the large turntable 2 rotates, the grinding wheel mold in each die hole group 3 passes through the above-mentioned sixteen stations in turn, and three grinding wheels can be formed at one time, thereby increasing the manufacturing output of the grinding wheel.

[0057] The grinding wheel mold passes through the lifting station 10: the lifting station 10 is provided with a post-mold removal lifting device 26 connected and fixed to the base frame 1, and the grinding wheel mold is lifted upward by the post-mold removal lifting device 26. Specifically, the post-mold removal lifting device 26 includes a fixed bottom plate 261, a fixed top plate 262, a guide rod 263, a lifting cylinder 264, a lifting plate 265 and a lifting rod group 266, as shown in FIG. Figure 4 The fixed top plate 262 is connected and fixed to the bottom frame 1 , the fixed top plate 262 and the fixed bottom plate 261 are arranged in an upper and lower space, three guide rods 263 are arranged 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 by the three guide rods 263 .

[0058] A lifting plate 265 is slidably connected between the fixed top plate 262 and the fixed bottom plate 261. Three guide rods 263 penetrate the lifting plate 265. The lifting plate 265 is arranged horizontally. Three linear bearings are arranged on the lifting plate 265. The linear bearings are slidably connected with the guide rods 263, so that the lifting plate 265 can slide up and down smoothly. A lifting cylinder 264 is arranged below the fixed bottom plate 261. The lifting cylinder 264 is upwardly connected to the lifting plate 265 to control the up and down movement of the lifting plate 265. Three groups of ejector rod groups 266 are arranged on the lifting plate 265. The three groups of ejector rod groups 266 correspond to the three mold holes in a mold hole group 3 respectively. Each group of ejector rod groups 266 includes three vertically arranged short ejector rods. The short ejector rods pass through the fixed top plate 262 upward and abut against the mold bottom plate 4b.

[0059] As a result, when the grinding wheel mold passes through the lifting station 10, the grinding wheel mold stops on the fixed top plate 262, and the mold bottom plate 4b is supported by the fixed top plate 262. After the mold is unloaded, the lifting device 26 is started: the lifting cylinder 264 drives the lifting plate 265 to move upward, and the short push rods move upward synchronously, and then the mold bottom plate 4b in the grinding wheel mold can be evenly lifted by the three short push rods, so that the mold bottom plate 4b moves upward. Then the lifting cylinder 264 retracts, and the short push rods move downward and withdraw from the grinding wheel mold.

[0060] The lifting station 10 is arranged between the mold unloading station 25 and the waxing station 11 to prevent the grinding wheel from failing to be removed at the mold unloading station 25. The post-mold unloading lifting device 26 at the lifting station 10 can lift the grinding wheel again, so that the grinding wheel can be removed manually, thereby dealing with the situation where the machine fails to remove the grinding wheel. At the same time, the lifting station 10 can lift the mold bottom plate 4b upward to perform manual waxing operations.

[0061] The grinding wheel mold passes through the waxing station 11: The waxing station 11 is provided with a bottom plate waxing device 27 and a waxing lifting device 30 corresponding to each other. The bottom plate waxing device 27 is arranged on the mounting ring plate 8, and the bottom plate waxing device 27 rotates downward to contact the grinding wheel mold. Specifically, the bottom plate waxing device 27 includes a waxing fixing plate 271, a waxing cylinder 272 vertically arranged on the waxing fixing plate 271, a motor mounting plate 273, and three waxing assemblies 274 arranged 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 horizontally up and down, and the waxing assembly 274 moves together, such as Figure 5 shown.

[0062] Each waxing assembly 274 includes a waxing motor 28 and a waxing plate 29 controlled by the waxing motor 28. The waxing plate 29 rotates downward with the mold ring 4a and the mold bottom plate 4b to form a wax layer on the surface of the grinding wheel mold. The waxing lifting device 30 is arranged on the base frame 1. The waxing lifting device 30 lifts the grinding wheel mold upward, specifically lifts the mold bottom plate 4b. The waxing lifting device 30 has the same structure as the lifting device 26 after unloading the mold, and the operating principle is also the same.

[0063] As a result, when the grinding wheel mold passes through the waxing station 11, the grinding wheel mold stops on the waxing lifting device 30, and the mold base plate 4b is supported by the waxing lifting device 30. The waxing lifting device 30 is started, and the mold base plate 4b is lifted up again by the short push rod. At the same time, the base plate waxing device 27 is started, and the three waxing components 274 are driven downward by the waxing cylinder 272, and the waxing motor 28 drives the rotating waxing disk 29 to wax the surface of the mold base plate 4b, which is convenient for the subsequent demoulding of the grinding wheel. Then the waxing lifting device 30 moves downward, the mold base plate 4b falls, the waxing cylinder 272 rises, and the waxing disk 29 no longer contacts the mold base plate 4b.

[0064] The grinding wheel mold passes through the reset station 12: This station can cause the mold bottom plate 4b to return to its initial state. The reset station 12 is provided with upper and lower corresponding bottom pressing plate devices 31 and reset lower support components 32, such as Figure 6The bottom pressing plate device 31 is arranged on the mounting ring plate 8, and the bottom pressing plate device 31 presses the grinding wheel mold downward. Specifically, the bottom pressing plate device 31 includes a supporting crossbeam 311 and three bottom pressing cylinders 312 arranged on the supporting crossbeam 311. The supporting crossbeam 311 is arranged on the mounting ring plate 8, and one end of the supporting crossbeam 311 is connected to the central column 7. Each bottom pressing cylinder 312 is vertically connected to a pressure plate 313 downward. The bottom pressing cylinder 312 can drive the pressure plate 313 to move up and down, and then use the pressure plate 313 to press the mold bottom plate 4b, so that the mold bottom plate 4b is restored to the lowest position in the mold ring 4a.

[0065] The reset lower support assembly 32 can ensure that when the mold base plate 4b is pressed, the mold base plate 4b is prevented from slipping out of the mold ring 4a. The reset lower support assembly 32 is arranged on the base frame 1, and the reset lower support assembly 32 abuts against the grinding wheel mold upward to support the mold base plate 4b. The reset lower support assembly 32 includes a lower pad 321, a heating plate 322 and a heat insulation plate 323 stacked in sequence from top to bottom, and the lower pad 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" shape in cross section.

[0066] As a result, when the grinding wheel mold passes through 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 started, and the bottom pressing cylinder 312 drives the pressure plate 313 to move down, and the three pressure plates 313 are used to press the mold base plates 4b in the three grinding wheel molds, so that the mold base plates 4b that were originally lifted up are reset downward, ensuring that the mold base plates 4b are arranged flatly at the lowest position of the mold ring 4a. Then the pressure plate 313 moves up and out of the grinding wheel mold without interfering with the operation of the large turntable 2.

[0067] The grinding wheel mold passes through the net placing station 13: This station can place the glass fiber mesh into the grinding wheel mold. The net placing station is provided with a mesh separation and picking device 33 and a mesh stack storage table 36 corresponding to the upper and lower meshes. The mesh separation and picking device 33 picks up the mesh on the mesh stack storage table 36 and delivers it to the grinding wheel mold. Figure 7 shown.

[0068] The mesh stack storage platform 36 is arranged on the bottom frame 1, and the mesh stack storage platform 36 includes a mesh stand 361, a rodless cylinder 362, a mesh changing slide 363 controlled by the rodless cylinder 362, two groups of stacking components and a top mesh component 37, as shown in FIG. Figure 8 and Fig. 9 The mesh stand 361 is a double-layer plate frame structure, and a rodless cylinder 362 is horizontally arranged on the mesh stand 361. The rodless cylinder 362 is connected to the mesh changing slide 363, and can drive the mesh changing slide 363 to move back and forth. The mesh changing slide 363 is slidably connected to the mesh stand 361 through a slide rail slider, which improves the smooth movement of the mesh changing slide 363.

[0069] Since there are two sets of stacking components, and one set of stacking components is arranged on each side of the screen changing slide plate 363. The screen changing slide plate 363 can drive the two sets of stacking components to move simultaneously. The two sets of stacking components are used alternately. That is, when one set of stacking components is cooperating with the mesh separating and picking device 33 for operation, workers can replenish the mesh on the other set of stacking components for standby use. Thus, fiberglass meshes can be added in the non-stop state, enabling continuous operation of the equipment.

[0070] The stacking component includes three mesh threading units 38, and each mesh threading unit 38 includes a centering rod 381, a damping sleeve 382, and a mesh supporting plate 383. The centering rod 381 is vertically arranged on the screen changing slide plate 363. A damping sleeve 382 is coaxially arranged at the upper end of the centering rod 381. The damping sleeve 382 is a tapered ring sleeve with thinner ends and a thicker middle. The maximum diameter of the damping sleeve 382 is larger than the diameter of the centering rod 381, which is convenient for separating the meshes one by one. Multiple long slots are provided on the damping sleeve 382, and the multiple long slots are circumferentially arranged on the damping sleeve 382. The long slots extend downward from the top surface of the damping sleeve 382 and approach the bottom surface of the damping sleeve 382.

[0071] A mesh supporting plate 383 is sleeved on the centering rod 381. The mesh supporting plate 383 is slidably connected up and down on the centering rod 381. A number of fiberglass meshes are sleeved on the centering rod 381 and supported by the mesh supporting plate 383, thus forming a mesh stack. When the mesh stack component moves upward, the meshes are gradually moved out of the centering rod 381 upward through the damping sleeve 382. The upward movement of the mesh stack is realized by the top mesh component 37.

[0072] The top mesh component 37 is arranged below the mesh table 361. The top mesh component 37 is arranged below a set of stacking components, and the installation position of the top mesh component 37 is fixed. The number of the top mesh components 37 is three, and the three top mesh components 37 correspond one by one to the three mesh threading units 38 in a set of stacking components. The top mesh component 37 is used to promote the upward movement of the mesh supporting plate 383, thereby lifting the mesh stack.

[0073] Each top mesh component 37 includes a hanging bracket 371, a lifting slider 372, and a long top rod 373. The cross-section of the hanging bracket 371 is in a "U" shape. The hanging bracket 371 is fixedly connected to the mesh table 361. A top mesh cylinder 374 is arranged below the hanging bracket 371. A lifting slider 372 is slidably connected above the hanging bracket 371. The lifting slider 372 is connected to the top mesh cylinder 374 and can drive the lifting slider 372 to move up and down. Three long top rods 373 are circumferentially arranged above the lifting slider 372. The long top rods 373 pass upward through the screen changing slide plate 363 and abut against the lower side of the mesh supporting plate 383. The mesh supporting plate 383 can be lifted up and down by the long top rods 373.

[0074] The mesh separation and picking device 33 is arranged on the mounting ring plate 8, and the mesh separation and picking device 33 comprises a mesh linear module 331 and a picking mechanism 332 controlled by the mesh linear module 331, such as Fig.10 The mesh linear module 331 adopts a synchronous belt module, and the 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 the mesh and delivering it into the grinding wheel mold.

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

[0076] The three adhesive belt picking units 35 pick up the meshes on the three mesh threading units 38 in the same stacking unit. One of the adhesive belt picking units 35 operates independently and is independently equipped with a power source. The other two adhesive belt picking units 35 share a side frame 39 and are driven by a power source to operate. Taking the coordinated operation of the other two adhesive belt picking units 35 as an example, the structure is explained: the adhesive belt picking units 35 are arranged at both ends of the side frame 39, and the driving cylinder 40 is arranged in the middle of the side frame 39. The driving cylinder 40 drives the two adhesive belt picking units 35 to operate at the same time.

[0077] The tape pick-up unit 35 includes an unwinding shaft 401, a rewinding shaft 402, a tape 403, a guide block 404, a de-netting cylinder 405, and a de-netting plate 406 controlled by the de-netting cylinder 405. Figure 11~Figure 13 As shown. The unwinding shaft 401 is fixedly installed on the side frame 39. The two ends of the unwinding shaft 401 pass through the side frame 39 and are rotatably connected to the unwinding roller 41. The outer contour of the unwinding roller 41 is a quadrangular prism with rounded corners. The unwinding roller 41 is sleeved with a rolled tape 403. The tape 403 is made of glass fiber reinforced tape 403. The tape 403 is interference-connected with the unwinding roller 41, and then the tape 403 and the unwinding roller 41 rotate together. A nut is threadedly connected to the end of the unwinding shaft 401. A brake pad 43 is sleeved on the end of the unwinding shaft 401. The tightened nut is used to squeeze the brake pad 43 and make the brake pad 43 in close contact with the unwinding roller 41 to prevent the unwinding roller 41 from rotating easily.

[0078] The winding shaft 402 is rotatably connected to the side frame 39 through a bearing seat, and both ends of the winding shaft 402 are respectively connected to winding rollers through the side frame 39 keys. The cross-section of the winding roller is "T"-shaped, and a locking cap 44 is threadedly connected to the end of the winding shaft 402. A retaining ring 45 is also sleeved on the end of the winding shaft 402. After tightening the locking cap 44, the retaining ring 45 is pressed tightly against the end of the winding roller, and then the winding roller and the retaining ring 45 are connected and combined, and the cross-section is in the shape of an I-shaped wheel.

[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 semicircular shapes. The guide blocks 404 are located below the reel 402 and the unreel 401. The adhesive tape 403 is drawn out, passes around a corresponding guide block 404, and is connected to the corresponding reel. There are two types of adhesive tapes 403 arranged in one adhesive tape pickup unit 35. The adhesive tape 403 on the unreel 401 is used for release, and the reel 402 is used for rewinding and recycling the released adhesive tape 403.

[0080] It should be noted that in the two tape-type pickup units 35 on the side frame 39, the reel shafts 402 are close to each other, and the unreel shafts 401 are far away from each other. In addition, the reel shaft 402 is connected to a spur gear 46 through a one-way bearing, and a vertically arranged rack 47 is connected to the piston rod of the driving cylinder 40. The rack 47 is arranged between the spur gears 46 on the two reel shafts 402. Both end surfaces of the rack 47 are machined with teeth, so that the rack 47 is meshed with the two spur gears 46 at the same time. When the rack 47 moves downward, the one-way bearing rotates itself, and the reel shaft 402 does not rotate; when the rack 47 moves upward, the one-way bearing drives the reel shaft 402 to rotate counterclockwise, and then the tape 403 is reeled onto the reel roller. In short, each time the rack 47 reciprocates up and down, the tape 403 on the unwinding roller 41 can be released to a certain length and the tape 403 on the winding roller can be wound to a certain length, thereby realizing the renewal of the tape 403 at the position of the guide block 404 and ensuring the adhesion to the mesh.

[0081] The glass fiber mesh can be fixed between the two guide blocks 404 by the adhesive force of the two adhesive tapes 403 at the guide block 404, so that the mesh can be picked up. However, when the mesh is put in, a mesh withdrawal cylinder 405 is arranged in the side frame 39, and the mesh withdrawal cylinder 405 is located between the unwinding shaft 401 and the winding shaft 402. The mesh withdrawal cylinder 405 is connected downward with a mesh withdrawal plate 406, which is a circular hollow plate, and the purpose is to make way for the guide block 404 and the damping sleeve 382. The mesh withdrawal plate 406 is surrounded between the two guide blocks 404. The mesh can be separated from the adhesive tape 403 by the downward movement of the mesh withdrawal plate 406, and then moved downward away from the guide block 404.

[0082] As a result, when the grinding wheel mold passes through the mesh placing station, the grinding wheel mold stops on the slideway 9 and the slideway 9 supports the mold bottom plate 4b. The top mesh assembly 37 moves upward to cause the mesh stack to move upward, ensuring that the top layer of the mesh stack is close to the damping sleeve 382; the picking cylinder 34 drives the tape-type picking unit 35 downward to use the tape 403 at the position of the guide block 404 to bond the top layer of the mesh stack, and then the picking cylinder 34 moves upward to drive the mesh to pass through the damping sleeve 382 and then separate from the centering rod 381. The damping sleeve 382 ensures that only one mesh separates from the centering rod 381 each time. The mesh linear module 331 drives the tape-type picking unit 35 to move above the grinding wheel mold, and then the picking cylinder 34 drives the mesh to move downward, and the mesh withdrawal cylinder 405 moves downward to drive the mesh withdrawal plate 406 to move downward, causing the mesh to separate from the guide block 404, thereby delivering the mesh head to the grinding wheel mold.

[0083] The grinding wheel mold passes through the net measuring station 14: the net measuring station 14 is provided with a net measuring device 48 connected and fixed on the mounting ring plate 8 for detecting whether there is a net in the grinding wheel mold. The net measuring device 48 includes a net measuring frame 481 and three net measuring sensors 482 connected to the net measuring frame 481, such as Fig.14 The mesh sensor 482 is a color mark sensor or a visual camera, which can determine whether the mesh exists. When the grinding wheel mold passes through the mesh measuring station 14, the slideway 9 supports the mold bottom plate 4b.

[0084] The grinding wheel mold passes through the grill station 15: The grill station 15 is provided with a grill device 49 connected and fixed to the mounting ring plate 8. The grill device 49 includes a grill fixing plate 491, a grill cylinder 492, a grill lifting plate 493 and a grill cover 494. The grill fixing plate 491 is provided with a grill cylinder 492, the grill cylinder 492 is vertically downwardly connected to the grill lifting plate 493, and three grill covers 494 are circumferentially arranged on the grill lifting plate 493, and each grill cover 494 is provided with an electric ceramic furnace heating plate, such as Fig.14 The grilling net cylinder 492 is used to drive the grilling net cover 494 to move downward, so that the grilling net cover 494 is placed on the grinding wheel mold, and the glass fiber mesh is heated by the electric ceramic furnace heating plate. When the grinding wheel mold passes through the grilling net station 15, the slideway 9 supports the mold bottom plate 4b.

[0085] The grinding wheel mold passes through the mesh pressing station 16: the mesh pressing station 16 is provided with a mesh pressing device 50 and a mesh pressing lower support assembly 51 corresponding to the upper and lower parts. The mesh pressing device 50 is arranged on the mounting ring plate 8, and the mesh pressing device 50 presses the mesh in the grinding wheel mold downwards. Specifically, the mesh pressing device 50 includes a mesh pressing fixing plate 501, a mesh pressing cylinder 502 and a mesh pressing disk 503. The mounting ring plate 8 protrudes outwards to form a mesh pressing fixing plate 501. Three mesh pressing cylinders 502 are arranged on the mesh pressing fixing plate 501. Each mesh pressing cylinder 502 is elastically connected to a mesh pressing disk 503 vertically downwards. The elastic connection is achieved by a compression spring, and then the mesh pressing disk 503 can elastically press the mesh.

[0086] The pressing net lower support assembly 51 is arranged on the base frame 1, and the pressing net lower support assembly 51 has the same structure as the reset lower support assembly 32. The pressing net lower support assembly 51 abuts against the grinding wheel mold upwards, such as Fig.15 As shown. Thus, when the grinding wheel mold passes through the mesh pressing station 16, the grinding wheel mold stops on the mesh pressing lower support assembly 51, and the mold bottom plate 4b is supported by the mesh pressing lower support assembly 51. The mesh pressing device 50 is started, and the mesh pressing cylinder 502 drives the mesh pressing plate 503 to move downward and press the mesh into the grinding wheel mold.

[0087] The grinding wheel mold passes through the feeding station 17: this station adds resin grinding wheel abrasives into the grinding wheel mold. The feeding station 17 is arranged with a connected raw material vibration plate 52 and a feeding device 53. The raw material vibration plate 52 contains resin grinding wheel abrasives. The raw material vibration plate 52 is connected to the bottom frame 1 downward to ensure the fixed installation of the raw material vibration plate 52. The feeding device 53 is arranged on the mounting ring plate 8, and the grinding wheel raw material in the raw material vibration plate 52 flows evenly into the three grinding wheel molds through the feeding device 53.

[0088] The feeding device 53 includes a mixing barrel 531 with an open top, three opening and closing valves 532 circumferentially arranged at the bottom of the mixing barrel 531, three material blocking hoppers 533 circumferentially arranged below the mixing barrel 531, and a material guiding assembly 534 arranged below the mixing barrel 531. Figure 16~Figure 20 The mixing barrel 531 is a circular barrel, the raw material vibration plate 52 is connected to the mixing barrel 531, a mixing motor 60 is arranged above the mixing barrel 531, the output shaft of the mixing motor 60 is located at the center of the mixing barrel 531, the output shaft of the mixing motor 60 extends downward into the mixing barrel 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 barrel 531, and the material brushes 61 are in contact with the inner wall of the mixing barrel 531.

[0089] Three rectangular discharge ports 62 are provided at the bottom of the mixing barrel 531, and an opening and closing valve 532 is arranged at each discharge port 62, and the opening and closing valve 532 can control the size of the discharge port 62. The opening and closing valve 532 includes an adjustment bottom plate 54, an adjustment baffle 55 and an adjustment screw 56. The adjustment bottom plate 54 is fixedly connected to the bottom of the mixing barrel 531, and the adjustment baffle 55 is slidably connected above the adjustment bottom plate 54, and the adjustment baffle 55 is inserted into the discharge port 62. The adjustment screw 56 is threadedly connected to the adjustment bottom plate 54, and one end of the adjustment screw 56 is rotatably connected to the adjustment baffle 55. By manually operating the adjustment screw 56 to move the adjustment baffle 55, the size of the discharge port 62 can be changed.

[0090] The raw materials in the mixing barrel 531 fall downward into the material blocking hopper 533. The material blocking hopper 533 corresponds to the opening and closing valve 532 one by one. The mixing barrel 531 is downwardly connected to the material blocking hopper 533 through the opening and closing valve 532. The lower end of the material blocking hopper 533 is in the shape of a quadrangular pyramid. A cover plate 63 for blocking the opening and closing valve 532 is rotatably arranged in the material blocking hopper 533, that is, the cover plate 63 can be used to close the discharge port 62. Specifically, a rotating block 64 is rotatably arranged under the adjustment bottom plate 54 of each opening and closing valve 532. One end of the rotating block 64 extends into the material blocking hopper 533 and is connected and fixed to the cover plate 63. One side wall of the material blocking hopper 533 is open, which does not affect the rotation of the rotating block 64.

[0091] Here, a flip cylinder 65 is used to realize the rotation of the cover plate 63. Since there are three cover plates 63, one of the cover plates 63 is controlled by a flip cylinder 65 alone, and the other two cover plates 63 are controlled by one flip cylinder 65. Specifically, a connecting rod 66 is arranged between the rotating blocks 64 of the other two cover plates 63. On the basis of hinged installation, the piston rod of the flip cylinder 65 is connected to the connecting rod 66 through a fisheye bearing. Through the telescopic movement of the flip cylinder 65, the cover plate 63 can be driven to rotate up and down. The cover plate 63 rotates upward to close the discharge port 62, and rotates downward to open the discharge port 62.

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

[0093] As a result, when the grinding wheel mold passes through the feeding station 17, the grinding wheel mold stops on the slideway 9 and the mold bottom plate 4b is supported by the slideway 9. The raw material vibration plate 52 conveys a certain amount of raw materials into the mixing barrel 531. The cover plate 63 is first closed, and the material brush 61 is driven to rotate by the stirring motor 60, so as to promote the uniformity of the raw materials in the mixing barrel 531. Then the cover plate 63 is opened, and as the material brush 61 rotates, the raw materials are evenly guided into the grinding wheel mold through the discharge port 62, the material blocking hopper 533 and the material guide hopper 59, so as to realize the feeding operation.

[0094] The grinding wheel mold passes through the material spreading station 18: the material spreading station 18 is provided with a servo scraper 67 and a material spreading turntable 68 corresponding to each other. The servo scraper 67 is arranged on the mounting ring plate 8, and the servo scraper 67 extends downward into the grinding wheel mold, and in cooperation with the rotating grinding wheel mold, the raw material in the mold can be evenly scraped and leveled.

[0095] The servo scraper device 67 includes a servo electric cylinder 671, a scraper seat 672 controlled by the servo electric cylinder 671, and three scrapers 673 circumferentially arranged on the scraper seat 672. Fig.21 and Fig. 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 accuracy. Each scraper 673 is adjustable up and down with the scraper seat 672 to change the height position of the scraper 673. Specifically, the scraper 673 is installed on the fixed frame 69. The fixed frame 69 is slidably connected to the scraper seat 672 through a linear bearing and a guide rod structure. The fixed frame 69 can move up and down. The scraper seat 672 is provided with a star handle 70. The star handle 70 is threadedly connected to the scraper seat 672 and is 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.
