Description

Technical Field

[0001] This utility model relates to the technology in the field of grinding wheel production and manufacturing, and in particular to a mesh feeding machine used in grinding wheel production and manufacturing. Background Technology

[0002] A grinding wheel is a bonded abrasive tool made of abrasive and bonding agent, widely used in metal processing, machinery manufacturing, stone cutting, and other fields. It performs grinding, cutting, and polishing operations on workpieces through high-speed rotation. Its core function is to remove the surface layer of the material through the sharp edge of the abrasive to achieve precision machining.

[0003] Currently, grinding wheels are typically composed of an abrasive layer, a transition layer, and a mesh. The transition layer connects the abrasive layer to the support structure at the center of the grinding wheel. It is usually made of metal or glass fiber and provides mechanical strength to prevent centrifugal breakage during high-speed rotation. The mesh mainly serves as a reinforcing structural material in the grinding wheel. The mesh is embedded in the abrasive layer or the transition layer and plays a role in improving the mechanical strength of the grinding wheel, preventing breakage, and improving dynamic balance.

[0004] During the manufacturing of grinding wheels, a forming mold is typically used for pressure molding. Before the grinding wheel is formed, a mesh fabric needs to be placed into the forming mold. However, in existing technologies, the mesh fabric is generally placed into the forming mold one by one manually. This method is labor-intensive, increases labor costs, and is relatively inefficient. Furthermore, it is prone to operator injury due to operational errors, posing a significant safety hazard. Therefore, it is necessary to research a solution to these problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a mesh feeding machine for grinding wheel production, which can effectively solve the problems of high manpower consumption, increased labor costs, low efficiency and easy safety accidents caused by the existing manual feeding of mesh.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mesh fabric feeding machine for grinding wheel manufacturing is installed beside a forming mold and includes a frame, a lifting device, and a pasting and translating device. The frame has a worktable with a positioning shaft extending vertically to center the mesh fabric. The lifting device includes a mesh fabric tray and a first drive mechanism. The mesh fabric tray is movably mounted on the worktable and located around the positioning shaft. The first drive mechanism is mounted on the frame and drives the mesh fabric tray to move up and down. The pasting and translating device includes a sliding frame, a second drive mechanism, a tape release / retraction assembly, and a mesh fabric spring-off assembly. The frame is slidably mounted on the machine frame, sliding back and forth between the worktable and the molding die. Adhesive tape guide blocks are provided on both sides of the bottom of the sliding frame. The second drive mechanism is mounted on the machine frame and drives the sliding frame to move back and forth. There are two adhesive tape release / retraction assemblies, mounted on the sliding frame and located beside the two adhesive tape guide blocks. The mesh opening assembly includes an opening plate and a third drive mechanism. The opening plate is movably mounted up and down at the bottom of the sliding frame and around the adhesive tape guide blocks.

[0009] As a preferred embodiment, there are two sliding frames, which are set separately along the conveying direction of the mesh fabric. The second drive mechanism drives the two sliding frames to move back and forth synchronously in the lateral direction. Each sliding frame is equipped with a tape release and retraction component and a mesh fabric spring-opening component.

[0010] As a preferred embodiment, the workbench surface has a receiving cavity below it, and the bottom of the mesh tray is connected to a top rod. The top rod passes through the workbench surface and extends into the receiving cavity. The first driving mechanism is disposed in the receiving cavity. The first driving mechanism is a cylinder, which drives the mesh tray to move up and down back and forth through the top rod.

[0011] As a preferred embodiment, the frame has a crossbeam that spans between the top of the worktable and the top of the forming mold. The bottom of the crossbeam is provided with a slide rail, and the sliding frame is mounted on the slide rail by a slider and moves back and forth laterally along the slide rail.

[0012] As a preferred embodiment, the second drive mechanism includes two synchronous pulleys, a stepper motor, and a synchronous belt. The two synchronous pulleys are rotatably mounted at the bottom of both ends of the crossbeam. The stepper motor is fixed to one end of the crossbeam and drives one of the synchronous pulleys to rotate. The synchronous belt is connected between the two synchronous pulleys, and the sliding frame is fixedly connected to the synchronous belt.

[0013] As a preferred embodiment, the tape unwinding and rewinding assembly includes a tape unwinding wheel and a tape rewinding wheel, which are located above both ends of the tape guide block, respectively.

[0014] As a preferred embodiment, the third drive mechanism is a cylinder.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0016] By using a lifting device to lift the entire set of mesh fabric, and using an adhesive translation device to stick the mesh fabric sheet by sheet and move it directly above the forming mold, and then using a mesh fabric spring-off component to separate the mesh fabric from the adhesive tape and drop it into the forming mold, the automatic feeding of mesh fabric is achieved, replacing the traditional manual feeding method.

[0037] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is disposed on the side of the molding mold 10 and includes a frame 20, a lifting device 30, and a pasting and translation device 40.

[0038] The frame 20 has a worktable 21, on which a positioning shaft 22 is provided for centering the mesh fabric 50. The positioning shaft 22 extends vertically. In this embodiment, the worktable 21 has two positioning shafts 22, which are separately arranged along the conveying direction of the mesh fabric 50. The two positioning shafts 22 respectively center-position two sets of mesh fabrics 50 of different sizes. In addition, the frame 20 has a crossbeam 23, which spans between the top of the worktable 21 and the top of the forming mold 10. The bottom of the crossbeam 23 is provided with a slide rail 24. In addition, the worktable 21 has a receiving cavity 201 below it.

[0039] The lifting device 30 includes a mesh tray 31 and a first drive mechanism 32. The mesh tray 31 is movably mounted on the worktable 21 and located around the positioning shaft 22. The first drive mechanism 32 is mounted on the frame 20 and drives the mesh tray 31 to move up and down. In this embodiment, one lifting device 30 is provided for each positioning shaft 22, i.e., there are two lifting devices 30, which lift two sets of mesh fabrics 50 respectively. Furthermore, a top rod 33 is connected to the bottom of the mesh tray 31. The top rod 33 passes through the worktable 21 and extends into the receiving cavity 201. There are multiple top rods 33. The first drive mechanism 32 is located in the receiving cavity 201. The first drive mechanism 32 is a cylinder, which drives the mesh tray 31 to move up and down through the top rods 33.

[0040] The adhesive applicator 40 includes a sliding frame 41, a second drive mechanism 42, an adhesive tape release and retraction assembly 43, and a mesh fabric spring-off assembly 44. The sliding frame 41 is slidably mounted on the frame 20, and slides back and forth between the worktable 21 and the molding die 10. Adhesive tape guide blocks 411 are provided on both sides of the bottom of the sliding frame 41. The second drive mechanism 42 is mounted on the frame 20 and drives the sliding frame 41 to move back and forth. There are two adhesive tape release and retraction components 43, which are mounted on the sliding frame 41 and located beside the two adhesive tape guide blocks 411. The mesh fabric spring-opening component 44 includes a spring-opening plate 441 and a third drive mechanism 442. The spring-opening plate 441 is movably mounted on the bottom of the sliding frame 41 and located around the adhesive tape guide blocks 411. The third drive mechanism 442 is mounted on the sliding frame 41 and drives the spring-opening plate 441 to move up and down.

[0041] In this embodiment, there are two sliding frames 41. The two sliding frames 41 are set separately along the conveying direction of the mesh fabric 50. Both sliding frames are mounted on the slide rail 24 by sliders 412 and move back and forth laterally along the slide rail 24. Each sliding frame 41 is provided with a tape release and retraction assembly 43 and a mesh fabric spring-opening assembly 44.

[0042] The second drive mechanism 42 drives the two sliding frames 41 to move back and forth synchronously. Specifically, the second drive mechanism 42 includes two synchronous pulleys 421, a stepper motor 422 and a synchronous belt 423. The two synchronous pulleys 421 are rotatably mounted at the bottom of both ends of the crossbeam 23. The stepper motor 422 is fixed to one end of the crossbeam 23 and drives one of the synchronous pulleys 421 to rotate. The synchronous belt 423 is connected between the two synchronous pulleys 421. Both sliding frames 41 are fixedly connected to the synchronous belt 423. The synchronous belt 423 rotates back and forth, thereby driving the two sliding frames 41 to slide back and forth laterally along the slide rail 24.

[0043] The tape unwinding and rewinding assembly 43 includes a tape unwinding roller 431 and a tape rewinding roller 432. The tape unwinding roller 431 and the tape rewinding roller 432 are respectively located above the two ends of the tape guide block 411. The tape unwinding roller 431 is used to unwind the tape 60, and the tape rewinding roller 432 is used to rewind the tape 60. The tape 60 is wrapped around the bottom surface of the tape guide block 411.

[0044] The spring-loaded plate 441 is a steel plate and a flat plate. The spring-loaded plate 441 has a through hole (not shown in the figure) for the tape guide block 411 to pass through. The third drive mechanism 442 is a cylinder, but it can also be other types of drive mechanisms, without limitation.

[0045] The working principle of this embodiment is described in detail below:

[0046] In use, both the lifting device 30 and the pasting and translation device 40 are connected to an external controller. The external controller controls the lifting device 30 and the pasting and translation device 40 to work together. First, two sets of mesh fabrics 50 of different sizes are placed on the mesh fabric trays 31 of the two lifting devices 30 respectively, and the two positioning shafts 22 center the two sets of mesh fabrics 50. Then, adhesive tape 60 is installed on each adhesive tape release and retraction assembly 43, so that each adhesive tape 60 passes around the bottom surface of each adhesive tape guide block 411, and the pasting surface of each adhesive tape 60 faces down towards the mesh fabric 50.

[0047] Next, the external controller is activated. In its initial state, the two sliding frames 41 are positioned directly above the two mesh trays 31. First, the two lifting devices 30 drive the two sets of mesh fabric 50 upwards, bringing them closer to the bottom of the two sliding frames 41. This allows the topmost mesh fabric 50 of each set to adhere to the corresponding adhesive tape 60. Then, the two lifting devices 30 drive the remaining mesh fabric 50 downwards to reset. Next, the second drive mechanism 42 operates, causing the two sliding frames 41 to move sequentially to directly above the molding die 10. When the sliding frame 41 moves to directly above the molding mold 10, the mesh fabric spring-off component 44 on it presses the corresponding mesh fabric 50 downward, causing the corresponding mesh fabric 50 to separate from the corresponding adhesive tape 60 and fall into the molding mold 10 under the action of gravity. After two mesh fabrics 50 of different specifications fall into the molding mold 10 in sequence, the second drive mechanism 42 works to drive the two sliding frames 41 to move in the opposite direction and reset, so that the two sliding frames 41 move directly above the two mesh fabric trays 31 respectively, and then the above-mentioned action is repeated to perform the next cycle, thereby realizing the continuous automatic feeding of mesh fabric 50. After the adhesive surface of the adhesive tape 60 loses its adhesiveness due to the repeated bonding of mesh fabric 50, the adhesive tape take-up roller 432 rewinds the old adhesive tape 60 and pulls out a new adhesive tape 60 from the adhesive tape unwind roller 431, and then uses the new adhesive tape 60 to bond the mesh fabric 50.

[0048] The key design feature of this invention is that it utilizes a lifting device to lift the entire mesh fabric, and in conjunction with a pasting and translation device to stick each mesh fabric sheet up and move it directly above the forming mold. Then, a mesh fabric spring-off component separates the mesh fabric from the adhesive tape, allowing it to fall into the forming mold. This achieves automatic feeding of the mesh fabric, replacing the traditional manual feeding method. This effectively reduces labor costs and labor consumption, while also greatly improving production efficiency and preventing safety accidents, thus bringing convenience to production operations.

[0049] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
