Technical Field

[0001] This invention belongs to the field of grinding wheel manufacturing equipment, specifically relating to a fully automatic rotary sixteen-station three-cavity grinding wheel forming machine. Background Technology

[0002] Currently, most multi-cavity forming machines for large-scale cutting abrasive wheels are push-type models, which suffer from varying degrees of problems such as low positioning accuracy, unstable operation, and high failure rate. To improve production efficiency, two sets of equipment would need to be installed, which would inevitably increase investment costs and require a larger floor space. Summary of the Invention

[0003] This invention provides a fully automatic rotary sixteen-station three-cavity grinding wheel forming machine, which uses a rotary turntable to reduce the floor space and allows for multi-station, multi-cavity operation, thereby improving processing efficiency.

The turntable is sleeved on the middle smooth section via bearings. The turntable gear is connected to the turntable motor and drives the turntable to rotate relative to the vertical central shaft. The upper threaded section passes through the upper crossbeam of the floating pressing device and is locked by a nut. The lower threaded section passes through the lower crossbeam of the floating pressing device and is locked by a nut. Several stations are set on the turntable, and each station is arranged in a ring around the vertical central shaft. Each station... Each station has at least two mold cavities; the turntable has a positioning groove and a position sensing block at each station; a position detection switch is installed at each station; the position detection switch corresponds to the position sensing block, and the position detection switch and the position sensing block work together to detect the real-time position of the turntable. A vertical central shaft is used as the support shaft of the turntable, and the upper and lower ends of the vertical central shaft are threaded sections, which are fixed to the upper and lower crossbeams with nuts.

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

[0040] A fully automatic rotary sixteen-station three-cavity grinding wheel forming machine, such as Figure 1 and 2 As shown, it includes a frame 1 and a rotary table mechanism 2. The frame 1 has two layers, as shown below. Figure 3 As shown, the upper layer serves as the main mounting end face, while the lower layer acts as a counterweight to increase the weight of the frame and make it more stable after placement. The floating pressing device 11, as the main grinding wheel forming equipment, occupies the largest space, so the frame has a mounting slot at the mounting location of the floating pressing device 11.

[0041] like Figure 4-6 As shown, the rotary table mechanism 2 includes a vertical central shaft 21, a turntable 22, a turntable motor 23, a turntable gear 24, and a turntable positioning structure 25. The vertical central shaft serves as the support shaft for the turntable and the floating pressing device. The vertical central shaft 21 includes an upper threaded section 211, a middle smooth section 212, and a lower threaded section 213. The turntable gear 24 is mounted on the lower end face of the turntable 22. The turntable is sleeved on the middle smooth section 212 through a bearing. The turntable gear 24 is connected to the turntable motor 23 and drives the turntable to rotate relative to the vertical central shaft 21. A driving pinion is mounted on the output shaft of the turntable motor, and the driving pinion meshes with the turntable gear. The upper threaded section 211 passes through the upper crossbeam of the floating pressing device 11, and upper nuts are provided above and below the upper crossbeam. The two upper nuts can fix the upper crossbeam on the one hand, and provide space for changing the height of the upper crossbeam on the other hand. The lower threaded section 213 passes through the lower crossbeam of the floating pressing device 11, and lower nuts are provided on both sides of the lower crossbeam. The lower nuts near the turntable can prevent the turntable from sliding down. The turntable is also provided with a turntable hollow shaft. The lower end of the turntable hollow shaft abuts against the lower crossbeam. The lower threaded section 213 passes through the turntable hollow shaft. The turntable hollow shaft mainly lifts the turntable away from the lower crossbeam. The bearing is installed between the turntable hollow shaft and the turntable. The rotation of the driving pinion will drive the turntable gear to rotate. The turntable gear is fixedly connected to the turntable, so the turntable 22 will rotate relative to the vertical central shaft.

[0042] Sixteen stations are set on the turntable 22, and each station has three mold cavities. The stations are arranged in a ring around the vertical central axis 21. In order to facilitate the control of the rotation of the turntable, each station of the turntable 22 is equipped with a positioning groove and a position sensing block. An arrival detection switch is installed at one of the stations. The arrival detection switch corresponds to the position sensing block. The arrival detection switch and the position sensing block work together to detect the real-time position of the turntable.

[0043] like Figure 7 As shown, the turntable positioning structure 25 includes a turntable positioning bracket 251, a turntable positioning moving part 252, and a turntable positioning block 253. The turntable positioning bracket 251 is fixed on the frame 1, the turntable positioning moving part 252 is installed on the turntable positioning bracket 251, the moving part of the turntable positioning moving part 252 is connected to the turntable positioning block 253, the turntable positioning moving part 252 drives the turntable positioning block 253 to reciprocate along the radial direction of the turntable 22, and the turntable positioning block 253 switches between abutting the positioning groove and moving away from the positioning groove. The turntable positioning bracket 251 is located on the outer edge of the upper platform of the machine frame. The turntable positioning moving part 252 only needs to be able to move linearly, and the turntable positioning block can move back and forth along the radial direction of the turntable. When it abuts against the positioning groove, the turntable is locked, and when it leaves the positioning groove, the turntable is unlocked. In order to simplify the structure, the turntable positioning moving part 252 preferably uses a cylinder. The piston rod of the cylinder is connected to the turntable positioning block. In order to ensure linear movement, a linear slide rail is installed on the turntable positioning bracket 251. The turntable positioning block 253 is installed on the slider of the linear slide rail. In order to avoid hard contact between the turntable positioning block and the positioning groove, the turntable positioning block uses a rotatable bearing. A bearing mounting block is fixed on the slider, and the bearing is installed on the bearing mounting block. The piston rod of the cylinder is connected to the bearing mounting block. The bearing mounting block follows the slider along the slide rail to approach and move away from the positioning groove.

[0044] The aforementioned workstations begin with the bottom pressing workstation 2201, and then proceed clockwise or counterclockwise as follows: bottom mesh placement workstation 2202, mesh baking workstation 2203, mesh pressing workstation 2204, material feeding workstation 2205, first scraping workstation 2206, second scraping workstation 2207, top mesh placement workstation 2208, mesh placement inspection workstation 2209, trademark core ring workstation 2210, first empty workstation 2211, pressing workstation 2212, second empty workstation 2213, mold removal workstation 2214, mold cleaning workstation 2215, and waxing workstation 2216.

[0045] A support plate 15 is installed above the turntable from the bottom pressing station to the trademark core ring station 2210. The support plate 15 is fixed on the bearing seat of the bearing. The support plate 15 provides corresponding installation positions for the bottom pressing plate device 3, the screen feeding device 4, the screen baking device 5, the screen pressing device 6, the volume-fixing feeding device 7, the scraping device 8, the screen feeding detection device 9, and the trademark core ring picking integrated machine 10.

[0046] A bottom-pressing plate device 3 is installed at the bottom-pressing station 2201; the bottom-pressing station is the beginning of the production station, and it resets the previously lifted mold bottom so that material can be put into the mold again, such as... Figure 8 The bottom plate device 3 includes a bottom plate support beam 31, a bottom plate cylinder mounting plate 32, a bottom plate cylinder 33, a bottom plate 34, and a bottom plate guide column; the bottom plate support beam 31 is installed radially on the support plate 15 and extends outward to the turntable and is fixed to the upper table of the frame 1.

[0047] The bottom pressing cylinder mounting plate 32 is fixed on the bottom pressing plate support beam 31 and corresponds to the three mold cavities of the bottom pressing station of the turntable below; a bottom pressing cylinder 33 is installed at the position corresponding to each mold cavity on the bottom pressing cylinder mounting plate 32. The piston rod of the bottom pressing cylinder 33 passes through the bottom pressing cylinder mounting plate 32 and connects to the bottom pressing plate 34, and drives the bottom pressing plate 34 to move closer to and away from the bottom pressing station.

[0048] To ensure the linear movement of the pressure plate, a pressure guide post is installed on both sides of each pressure cylinder 33. The two pressure guide posts are connected together by a guide connecting plate, which is fixed on the piston rod of the pressure cylinder. The pressure guide post can move up and down relative to the pressure cylinder mounting plate 32.

[0049] When the turntable moves to the bottom pressing position, the bottom pressing plate device 3 is activated, the bottom pressing cylinder extends, and the bottom pressing plate is lowered. The bottom pressing plate makes uniform contact with the bottom of the mold, causing the bottom of the mold to move down and reset to provide space for the raw materials.

[0050] The bottom mesh placement station 2202 is used to place the bottom reinforcing mesh into the mold cavity after the mold bottom is reset; the bottom mesh placement station 2202 is equipped with a mesh placement device 4; such as Figure 9As shown, the wire feeding device 4 includes a wire feeding mounting base plate 41, a wire feeding transverse movement mechanism 42, a wire storage mechanism 43, a translation mechanism 44, a wax removal paper mechanism 45, and a wire picking mechanism 46. The wire feeding mounting base plate 41 is fixed to the upper table of the frame and extends outward away from the turntable. The wire feeding transverse movement mechanism 42 includes a wire feeding transverse movement base plate 421 and a wire feeding transverse movement force component. The wire feeding transverse movement base plate 421 is mounted above the wire feeding mounting base plate 41 by a support column. The wire feeding transverse movement force component adopts a transverse rotation motor, a transverse drive wheel, and a transverse rotation mechanism. The structure of the overflow belt and the transverse driven wheel is as follows: the transverse rotary motor is fixed on the lower end face of the screen-laying transverse base plate 421, the output shaft of the transverse rotary motor is connected to the transverse driving wheel, the transverse driving wheel and the transverse driven wheel are connected by the transverse belt drive, the screen-laying transverse base plate 421 is provided with transverse clearance holes, the screen storage base plate 431 of the screen storage mechanism 43 is fixedly connected to the transverse belt, and in order to ensure the linearity of the movement of the screen storage base plate, a linear slide rail is provided between the screen storage base plate 431 and the screen-laying transverse base plate 421.

[0051] In order to change the height of the wire mesh supply, the lower end of the wire mesh transverse transfer substrate 421 is connected to the lifting cylinder 47.

[0052] The mesh storage mechanism 43 includes a mesh storage substrate 431, mesh threading rods 432, and mesh support plates 433. A plurality of mesh threading rods 432 are arranged on the mesh storage substrate 431, and a mesh support plate 433 is mounted on each mesh threading rod 432. The mesh is fitted onto the mesh threading rods and supported by the mesh support plates. In this embodiment, two sets are provided, each set having three mesh threading rods. When a set of mesh threading rods is used up, the mesh feeding and traversing mechanism traverses to switch to the spare set for mesh supply.

[0053] The translation mechanism 44 is driven by a rotary motor and synchronous belt. The dewaxing paper mechanism 45 and the wire mesh picking mechanism 46 are spaced apart and both connected to the synchronous belt. The translation mechanism 44 is arranged radially along the turntable and perpendicular to the setting direction of the wire mesh laying and traversing mechanism.

[0054] like Figure 10As shown, the wax removal paper mechanism 45 includes a wax removal paper cylinder mounting plate 451, a wax removal paper cylinder 452, a wax removal paper mounting base plate 453, a wax removal paper suction cup plate 454, and a wax removal suction cup 455. The wax removal paper cylinder mounting plate 451 is connected to the synchronous belt of the translation mechanism 44 and moves back and forth with the synchronous belt. The wax removal paper cylinder 452 is vertically mounted on the lower end of the wax removal paper cylinder mounting plate 451. The piston rod of the wax removal paper cylinder 452 is fixedly connected to the wax removal paper suction cup plate 454. 4. Three wax removal paper mounting positions are provided, and wax removal paper suction cup plate 454 is installed on the corresponding wax removal paper mounting positions. The wax removal paper suction cup plate 454 is provided with several wax removal stations. In this embodiment, wax removal suction cup 455 is installed on each of the three wax removal stations. The translation mechanism moves the wax removal paper mechanism 45 to the mesh storage substrate. The wax removal paper cylinder moves down to bring the wax removal suction cup close to the mesh and adsorb the wax paper on the mesh. After adsorption, the wax removal paper cylinder moves up, and the translation mechanism moves in the opposite direction to remove the wax paper on the mesh.

[0055] like Figure 11 As shown, the mesh picking mechanism 46 includes a mesh picking base plate 461, a mesh picking cylinder 462, and a mesh picking head 463. The mesh picking base plate 461 is fixedly connected to the synchronous belt of the translation mechanism. The mesh picking cylinder 462 is vertically installed at the lower end of the mesh picking base plate 461. The piston rod of the mesh picking cylinder 462 is connected to the mesh picking mounting plate. Three mesh picking heads 463 are installed on the mesh picking mounting plate. The structure and operating principle of the mesh picking head 463 are the same as those of the mesh picking unit of the 22-station large slice automatic forming machine of the dual press in announcement number CN222371369U, and will not be described in detail here.

[0056] The wire mesh pickup mechanism 46 and the dewaxing paper mechanism 45 move simultaneously with the synchronous belt, with the wire mesh pickup mechanism 46 being closer to the turntable. When the synchronous belt moves closer to the turntable, the dewaxing paper mechanism 45 moves towards the wire mesh storage mechanism, and the wire mesh pickup mechanism moves towards the pressing station while picking up the wire mesh. The dewaxing paper mechanism 45 picks up the wax paper on the wire mesh, and the wire mesh pickup mechanism places the picked-up wire mesh into the mold cavity. The synchronous belt then moves in the opposite direction to reset the dewaxing paper mechanism 45 and the wire mesh pickup mechanism 46.

[0057] When the amount of wire mesh on the wire mesh threading rod 432 is small, the lifting cylinder will lift the wire mesh transverse moving base plate 421 to facilitate the operation of the wax removal paper mechanism 45 and the wire mesh picking mechanism 46.

[0058] After the base mesh is placed, it is heated at the heating station. Heating station 2203 is equipped with a heating device 5. The heating device 5 has three heating mechanisms, and these mechanisms have the same structure and operating principle as the heating device of the automatic large-slice forming machine with a 22-station double press (publication number CN222371369U), which will not be described in detail here. Heating softens the mesh in the mold cavity and then presses it.

[0059] The softened mesh needs to be flattened on the mold base plate at the mesh pressing station 2204. The mesh pressing station is equipped with a mesh pressing device 6. Mesh pressing devices are installed at the three mold cavities of the mesh pressing station. The structure and principle of the mesh pressing device are the same as those of the mesh pressing device of the automatic large slice forming machine with double press 22 stations in announcement number CN222371369U.

[0060] After the bottom reinforcing mesh is flattened, it needs to be fed with material. A certain amount of molding material is automatically fed into the middle of the mold cavity. The feeding station 2205 is equipped with a fixed volume feeding device 7. like Figure 12 As shown, the constant volume feeding device 7 includes a vibrating hopper 71, a rotating feeding hopper 72, and a feeding port 73. The vibrating hopper 71 is mounted outside the frame via a mounting base, and the discharge end of the vibrating hopper 71 is connected to the inlet of the rotating feeding hopper 72. The rotating feeding hopper 72 is equipped with a stirring motor, a stirring shaft, and stirring blades. Stirring blades are mounted on the stirring shaft. The lower end of the rotating feeding hopper 72 is equipped with three feeding ports 73, and each feeding port 73 is equipped with a feeding baffle 74. The feeding baffle 74 is movable. In this embodiment, a screw and nut structure is used to change the position of the feeding baffle in the feeding port, thereby changing the opening degree of the feeding port.

[0061] After feeding, the resin molding material needs to be leveled. In this embodiment, two scraping stations are set up. The molding material is leveled through two scraping processes. Both the first scraping station 2206 and the second scraping station 2207 are equipped with scraping devices 8. Figure 13 As shown; After the molding material is scraped flat twice, a top reinforcing mesh is placed on it. A mesh placement device 4 is set at the top mesh placement station 2208. The mesh placement device 4 has the same structure as the mesh placement device at the bottom mesh placement station.

[0062] After the top net is placed, the net placement and inspection station 2209 performs top net inspection to avoid any omissions. The net placement and inspection station 2209 is equipped with a net placement and inspection device 9.

[0063] After the top screen inspection, the trademark and core ring are placed. Considering the layout factors, two workstations are set up, namely the trademark and core ring workstation 2210 and the first empty workstation 2211. The first empty workstation 2211 does not have a trademark and core ring picking machine 10 installed, but only serves as a workstation buffer. Therefore, the turntable positioning structure 25 is installed at the first empty workstation 2211.

[0064] A trademark core ring pickup and pickup integrated machine 10 is installed at the trademark core ring workstation 2210, such as Figure 14-16 As shown, the trademark core ring picking and picking integrated machine 10 includes a core ring vibratory plate 101, a core ring positioning and conveying mechanism 102, a core ring rotation magnetic attraction transfer mechanism 103, a core ring turntable lifting mechanism 104, a trademark storage lifting mechanism 105, a magnetic attraction moving mechanism 106, and a trademark core ring support plate 107.

[0065] The trademark core ring support plate 107 is installed on the upper platform of the frame 1. The core ring turntable lifting mechanism 104 and the trademark storage lifting mechanism 105 are installed on the trademark core ring support plate 107.

[0066] The core ring vibratory feeder 101 enables the continuous directional arrangement of core rings and transports them to the core ring vibratory feeder outlet, where they fall onto the core ring positioning and conveying mechanism 102.

[0067] The core ring positioning and conveying mechanism 102 includes a conveying bracket 1021, a conveying structure 1022, and a core ring positioning structure 1023. The conveying structure 1022 is installed inside the conveying bracket 1021. The conveying structure uses a belt conveyor. In order to prevent the core rings conveyed by the conveying structure from falling off the side, protective plates are also provided on both sides of the conveyor belt. The protective plates are adjustablely installed on the conveying bracket. By changing the distance between two adjacent protective plates, core rings of different sizes can be accommodated.

[0068] The feeding side of the conveying structure 1022 is located below the discharge side of the core ring vibratory feeder 101. In order to detect the discharge of the core ring from the vibratory feeder, a core ring detection sensor is installed on the conveying support 1021 on the feeding side of the conveying structure 1022. The core ring detection sensor is mounted on a sensor mounting plate, which is horizontally mounted on the conveying support and higher than the discharge side of the vibratory feeder.

[0071] The rotating power component 1031 uses a rotary motor. The output shaft of the rotary motor is connected to a rotating shaft via a coupling. The rotating shaft is mounted on a rotating shaft plate via bearings. The rotating shaft plate is fixed on the rotating magnetic base 1034, providing more favorable rotational support for the swing arm and the rotating drive wheel.

[0072] A swing arm position detection sensor is installed on the rotating magnetic base 1034, which is located away from the core ring picking side. A proximity switch is preferred. The sensor is used to detect the position of the swing arm rotation and represent the origin of the rotation.

[0073] The rotary swing arm structure 1032 includes a swing arm 10321, a rotary driving wheel 10322, a rotary driven wheel 10323, and a magnetic mounting base 10324. One end of the swing arm 10321 is connected to the output shaft of the rotary power component 1031 and rotates with the output shaft of the rotary power component 1031. The rotary driving wheel 10322 is mounted on the output shaft of the rotary power component 1031. The rotary driving wheel 10322 is connected to the rotary driven wheel 10323 in a transmission connection. The rotary driven wheel 10323 is mounted on the free end of the swing arm 10321 and rotates relative to the swing arm 10321. The magnetic mounting base 10324 is fixedly connected to the side end face of the rotary driven wheel 10323. The magnetic structure 1033 is mounted on the magnetic mounting base 10324. The magnetic structure is the same as the magnetic component in the automatic feeding device and method for grinding wheel hole rings in patent announcement number CN 117361068 A, and will not be described again here.

[0074] The core ring rotation magnetic transfer mechanism 103 transfers the core ring of the core ring positioning structure 1023 to the core ring turntable lifting mechanism 104.

[0075] The core ring turntable lifting mechanism 104 includes a core ring turntable 1041, a core ring turntable base plate 1042, a core ring rotary motor, and a core ring lifting cylinder 1043. The core ring turntable base plate 1042 is mounted on the trademark core ring support plate 107. The core ring rotary motor is mounted on the lower end face of the core ring turntable base plate 1042. The output shaft of the core ring rotary motor passes through the core ring turntable base plate 1042 and connects to the core ring turntable 1041. The core ring turntable 1041 is provided with six mandrel rods, which are arranged in a ring around the center of the core ring turntable. The mandrel rods near the core ring positioning structure 1023 are not provided with mandrel rods. A core ring lifting cylinder 1043 is positioned on the core ring turntable base plate 1042 at a distance from the mandrel through rod, using the mandrel through rod as a reference. The piston rod of the core ring lifting cylinder 1043 passes through the core ring turntable base plate 1042 to lift the core ring on the mandrel through rod. In this embodiment, the core ring lifting cylinder is connected to a connecting plate. Guide posts are provided on both sides of the connecting plate. The guide posts pass through the core ring turntable base plate 1042 and can move relative to the core ring turntable base plate 1042. The connecting plate connects the core ring lifting cylinder to the core ring turntable base plate 1042 via a column slider. The distance between the two guide posts is less than the outer diameter of the core ring, which is sufficient to lift the core ring.

[0076] The core ring rotary motor drives the core ring turntable 1041 to rotate, switching to receive the core rings transferred from the magnetic suction structure. When the core rings are full, the turntable rotates to the feeding position, allowing the magnetic suction moving mechanism 106 to pick up the core rings and place them into the mold cavity.

[0077] The trademark storage lifting mechanism 105 is equipped with three trademark storage lifting structures. The trademark storage lifting structures are the same as the trademark lifting unit structure and operating principle of the double-press 22-station large slice automatic forming machine (announcement number CN222371369U), which will not be described in detail here.

[0078] The magnetic moving mechanism 106 is arranged radially along the turntable and transfers the core ring from the core ring turntable lifting mechanism 104 and the trademark from the trademark storage lifting mechanism 105 to the workpiece at the trademark core ring station 2210.
